Description

Technical Field

[0001] This application relates to the field of fixture technology, and in particular to a fixture for grinding and flattening shaft workpieces. Background Technology

[0002] According to installation requirements, one end of the shaft workpiece has grinding grooves 29 on each of its two side walls, making one end of the shaft workpiece flat (see reference for specific structure). Figure 1 In the existing technology, when machining a shaft workpiece, the unmachined shaft workpiece is first fixed between two clamping plates. Then, the two clamping plates are installed on the working platform of the milling machine, so that one side of one end of the shaft workpiece can be cut. However, when it is necessary to cut the other side of one end of the shaft workpiece, the two clamping plates need to be separated and disassembled. Then, the shaft workpiece is rotated so that the other side of one end of the shaft workpiece is on top. Then, the two clamping plates come closer to each other to squeeze and fix the shaft workpiece. Then, the milling machine can cut the other side of one end of the shaft workpiece, which makes the machining efficiency of the shaft workpiece low. Utility Model Content

When machining both sides of one end of a shaft workpiece, first place multiple shaft workpieces in multiple fixed slots of a clamping plate, then place another clamping plate on top of the first clamping plate. Rotate the locking buckle to insert one end of the locking buckle into the slot. Then insert the pins into the locking buckle and the clamping plate in sequence, thereby clamping the shaft workpieces with the two clamping plates. Then the milling machine will work to machine one side of one end of the shaft workpiece. After one side of one end of the shaft workpiece is machined, rotate the two clamping plates 180° so that the other side of one end of the shaft workpiece is on top. Then the milling machine will machine the other side of one end of the shaft workpiece, thereby completing the machining of both sides of one end of the shaft workpiece, which improves the working efficiency of machining shaft workpieces.

[0014] 2. When encountering shaft workpieces of different lengths, start the drive motor. Under the meshing of the gear and rack, the first telescopic rod slides inside the second telescopic rod, causing the first clamping bar and the second clamping bar to move away from or closer to each other, thus adapting to shaft workpieces of different lengths.

[0023] The inner sides of both ends of the first clamping strip 4 are welded and fixed with brackets 13 respectively. The two brackets 13 are rotatably connected to the top of the mounting plate 1. The upper end face of the mounting plate 1 is provided with a rotating groove 14. The two clamping plates 2 can rotate in the rotating groove 14. The upper end face of the mounting plate 1 is rotatably connected with two limiting plates 15. The two limiting plates 15 are located on both sides of the rotating groove 14 respectively. When the two clamping plates 2 are in a horizontal state, the outer ends of the two limiting plates 15 rotate inward, so that the upper side of the limiting plate 15 abuts against the lower side wall of the clamping plate 2.

[0024] Reference Figure 3 and Figure 4The first telescopic rod 8 of the middle telescopic component 7 has a rack 16 integrally provided on its side wall. The second telescopic rod 9 has a connecting groove 17 on its side wall. A rotating seat 18 is installed and fixed on the outside of the second telescopic rod 9.
