Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1 to 5, the turnover table with any angle comprises a sliding base 2 and a working table top 4, wherein the sliding base 2 is arranged on a bed body 1 and can move on a bed body guide rail along a V-axis direction. The bottom of the working table top 4 is provided with a supporting seat 3, the center of the supporting seat 3 is provided with a rotating shaft, and the working table top 4 can rotate around the rotating shaft along the B-axis direction. One side of the upper part of the sliding seat 2 is fixed with a rotary support 8, the rotary support 8 is connected with a rotary shaft 9, and the rotary shaft 9 is connected with a support seat 3, so that the support seat 3 can drive the working table 4 to rotate (namely, an A shaft) around the rotary shaft 9, and a certain angle is formed between the working table 4 and the sliding seat 2.

A lead screw support 6 is fixed on one side of the upper portion of the sliding seat 2, which is opposite to the rotating support 8, a lead screw support shaft 7 is connected onto the lead screw support 6, an overturning lead screw 5 is connected onto the lead screw support shaft 7, the other end of the overturning lead screw 5 is connected onto an overturning shaft 14, and the overturning shaft 14 is fixed onto the supporting seat 3. The number of the turnover screw rods 5 is two, each turnover screw rod 5 is connected with one turnover shaft 14, the end part of each turnover shaft 14 is connected with one speed reducer 11, and the two speed reducers 11 are connected with the driving motor 13 through the feeding box 10. The two turnover screws 5 are driven by the driving motor 13 to extend and retract together, so that the supporting seat 3 can be supported or put down.

The overturning platform has V, B, A three axes: wherein the slide carriage 2 drives the supporting seat 3 and the working table top 4 to move along the lathe bed to form a V-axis; the worktable surface 4 rotates around the center of the supporting seat 3 to be a B axis; the supporting seat 3 drives the working table top 4 to rotate around the rotating shaft 9 to form an A shaft. When the workpiece turnover device works, a workpiece is placed on the working table top 4, and when the part is provided with a plurality of holes or surfaces with different angle requirements, the working table top 4 is turned over according to the angle requirements. When the turnover table is turned over, the reduction gearbox 10 and the speed reducer 11 are driven to rotate by the driving motor 13, the turnover lead screw 5 is driven by the 2 speed reducers 11 to rotate together, and the nut of the turnover lead screw 5 is fixed on the lead screw support 6, so that when the turnover lead screw 5 rotates, the turnover lead screw 5 can drive the support seat 3 and the working table top 4 to rotate around the rotating shaft 9, and the turnover table is turned over. Because the overturning motion of the A shaft is completed by driving the overturning lead screw 5 by the driving motor 13, the required alpha angle can be obtained only by controlling the displacement of the overturning lead screw 5 through a CNC (numerical control system), the manufacture of the tool during processing can be reduced, and the auxiliary time for adjusting when the tool is replaced is greatly reduced.
