Referring to Figures 1-3, a direction-adjustable machining fixture includes a base 1. The bottom of the base 1 is provided with a plurality of buffer pads, which can reduce vibration during machining and improve the processing quality of the workpiece. The base 1 One side of the upper surface is provided with a first support rod 2, the upper end of the first support rod 2 is provided with a spherical groove 3, the spherical groove 3 is provided with a matching ball 4, and the opening diameter of the spherical groove 3 is smaller than the diameter of the ball 4 size, and is larger than the diameter of the second support rod 6, the ball 4 is fixed in the spherical groove 3 to prevent it from falling off when it rotates, the top of the first support rod 2 is provided with a first fastening bolt 5, the surface of the ball 4 is evenly opened There are a plurality of threaded holes, and the first fastening bolt 5 penetrates the first support rod 2 and is threadedly connected with the ball 4, and the side of the ball 4 away from the first support rod 2 is fixedly connected with a second support rod 6, and the second support rod 6 The side wall away from the ball 4 is connected with a clamping device through the fixing rod 7. When the position of the workpiece needs to be adjusted during processing, the first fastening bolt 5 is unscrewed, and the second support rod 6 is rotated around the ball 4. , until the clamping device reaches the processing position, the direction fixing can be completed by threading the first fastening bolt 5 through the first support rod 2 and the threaded hole on the ball 4;

The clamping device includes a disc 9, a groove 11 is provided at the center of the disc 9, a bevel toothed disc 12 is rotatably connected in the groove 11, and a knob 8 is provided on one side wall of the disc 9 close to the fixing rod 7, and The knob 8 penetrates the disc 9 and is fixedly connected to the bevel gear disc 12. The surface of the disc 9 is also provided with four symmetrically arranged sliding grooves 14. 15. One end away from the groove 11 is fixedly connected with a clamping rod 10, the clamping rod 10 is arranged perpendicular to the disc 9, and the side wall of each clamping rod 10 is provided with anti-skid patterns to increase the clamping force and avoid the processing The workpiece falls off, and the moving block 15 is provided with a threaded hole, and the threaded hole is threadedly connected with a sleeve 18 with a threaded outer wall. The connecting rod 17 in the sleeve 18 is evenly provided with a plurality of threaded holes in the circumferential direction, the sleeve 18 is also threadedly connected with a second tightening bolt 20 , and the second tightening bolt 20 penetrates the thread on the sleeve 18 and the connecting rod 17 The end of the connecting rod 17 away from the bearing 19 is fixedly connected with the helical gear 13, and the helical gear 13 is meshed with the bevel gear plate 12. When clamping the workpiece, first place the workpiece between the four clamping rods 10. , the rotating knob 8 bevel gear 12 drives the four helical gears 13 to rotate, each helical gear 13 drives the connecting rod 17 to rotate, and the connecting rod 17 rotates in the sleeve 18, but when the connecting rod 17 and the sleeve 18 pass through When the second fastening bolts 20 are fixed together, the connecting rod 17 drives the sleeve 18 to rotate, and the sleeve 18 pushes the moving block 15 to move through the thread, so that the clamping rod 10 moves to realize the blessing. Control the movement of the clamping rods 10 individually until all the four clamping rods 10 clamp the workpiece. When it is necessary to control the movement of a clamping rod 10, then tighten the second tightening rod corresponding to the position of the clamping rod 10. The bolts 20 make the connecting rod 17 drive the sleeve 18 to rotate, and can drive the clamping rod 10 to displace by means of threaded connection. At the same time, the second tightening bolts 20 corresponding to the other three clamping rods In the loose state, the bevel gear 12 still drives the connecting rod 17 to rotate through the helical gear 13, but the connecting rod 17 is not fixed with the sleeve 18 and will rotate in the sleeve 18, so the sleeve 18 does not rotate, so this solution The four gripping bars 10 in the can be individually adjusted to suit irregularly shaped workpieces.

In the utility model, before machining, the workpiece is placed between the four clamping rods 10, the knob 8 is rotated to make the bevel gear plate 12 drive the four helical gears 13 to rotate, and each helical gear 13 drives the connecting rod 17 to rotate respectively.
