Description

Longitudinal clamping elastic positioning block structure

The invention relates to a positioning block for providing a fixed workpiece, in particular to an elastic positioning block structure which can quickly fix a plurality of workpieces at the same time for longitudinal machining of the processing machine.

According to the current automatic control processing machine, in order to process quickly and conveniently, all the processing parts will use a jig plate to clamp the workpiece, and then the upper and lower materials are automatically controlled by the processing machine, especially a pair of machining parts. The corners are pressed and clamped to enable the positioning block structure to be processed above the workpiece.

As shown in the seventh figure, it is a conventional positioning block structure for pressing and clamping the corners of the workpiece, comprising: a plurality of positioning blocks 10 and a plurality of locking members 20, and the matching is applied to a workpiece slot having at least one workpiece The workpiece slot 301 of the 301 is adapted to be received by the plurality of workpieces A, and is abutted against the corners of the workpiece slot 301. The bottom surface of the slot of the workpiece slot 301 is provided with a screw hole 302 between the workpieces A. The positioning block 10 is provided with a fixed locking hole 101 at the center thereof, and at least opposite sides are provided with a slanting abutting surface 102 which is tapered from the top to the bottom. The locking member 20 has an extending screw 201 and an end portion of the screw 201 The control terminal 202 is for rotation.

The positioning block 10 is received in the workpiece slot 301 of the fixture tray 30, and is placed between the two adjacent processing members A. After the locking member 20 passes through the fixed locking hole 101 of the setting block 10, the locking member 20 is inserted. The locking hole 302 is locked on the base 30, and the locking member 20 is locked, so that the control end 202 presses the positioning block 10, and the positioning block 10 is driven by the inclined abutting surface 102 to press the workpiece A downward. The upper corner A1 pushes the workpiece A toward the corner of the workpiece slot 301, and the workpiece A is clamped and fixed to the groove side of the workpiece slot 301 by the opposite sides 102 of the positioning block 10 to provide the workpiece. The top of A can be processed.

The positioning block structure includes a plurality of positioning blocks 10 and a plurality of locking members 20, and the locking holes 20 are screwed to the screw holes 302 of the jig plate 30, and the positioning block 10 is pressed down so that the opposite two oblique faces of the positioning block 10 The lower end angle A1 corresponding to the workpiece A is pressed downward to generate the positioning clamping workpiece A. The design has the following disadvantages: 1. Each positioning block 10 can only be used for one upper side of the two workpieces A. The angle is clamped and fixed. Therefore, the plurality of positioning blocks 10 are required to cooperate with the plurality of locking members 20 to fix the plurality of workpieces A in the workpiece slot 301. The fixing process of the rotation locking member 20 is time-consuming and labor-intensive. It is not conducive to processing mass production; Second, each processing part A needs to be fixed by two blocks 10 and two locking pieces 20, so that the locking force of the two locking pieces 20 is different, resulting in processing Piece A cannot achieve stable clamping and fixing, which affects the machining accuracy of the workpiece A.

The inventor has in view of the fact that the conventional positioning block structure has the operation time-consuming and labor-intensive, is not conducive to processing mass production, and is easy to cause the workpiece to be stably clamped and fixed, which affects the lack of processing precision, and is based on the idea of creation and creation. After a variety of discussions on design and trial sample testing, and multiple corrections and improvements, the final design of this creation.

The invention provides a longitudinally-positioned elastic positioning block structure, comprising: a positioning block and a locking component, which are matched and applied to a fixture disk having at least one workpiece groove, wherein the workpiece groove is accommodated by a plurality of workpieces, And abutting against the corners of the workpiece groove, the bottom surface of the groove of the workpiece groove The center of the positioning block is provided with a fixed locking hole, and at least four positioning rods extend from the center, the positioning rods are two in a group, and the two positioning rods are equally set. At the outer periphery of the fixed keyhole, the two positioning rods are provided with two slanting abutting surfaces and a clamping space, and the two positioning rods are a set of positioning rods and the other two are a set of positioning rods. An elastic space is provided, the locking member has an extended screw and a control end at the end of the screw for rotating, and the locking member is screwed through the fixed locking hole of the setting block, and is locked to the base. The screw hole allows the positioning block to be placed in the workpiece slot of the jig plate, and the processing component is located in each clamping space, and the locking piece is locked by the locking end, and the positioning block is pressed down by the control end thereof, and the positioning block is driven to be inclined The upper corner of the corresponding workpiece is pressed against the surface, and the workpiece is clamped and fixed.

The main purpose of the longitudinally-positioned elastic positioning block structure of the present invention is that the positioning block is locked by the screwing of a locking member, that is, the plurality of positioning rods can be simultaneously controlled to press and fix the plurality of processing members, and the quadrilateral is fixed. The processing part, a positioning block and a locking action can fix four workpieces at a time, and has the advantages of saving time and labor.

The secondary purpose of the longitudinally-positioned elastic positioning block structure of the present invention is that a minimum of one positioning block and a locking component can be used to fix a plurality of machining parts, and the utility model has the advantages of low component and simple low cost, and each of the positioning blocks The positioning rod is pressed against the average force, and the workpiece is stably clamped and fixed to ensure the processing precision of the workpiece.
