DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example 1: Figure 1-2 As shown, a parts fixing device for mechanical manufacturing processing includes a base 1 and two clamping blocks 2. The two clamping blocks 2 are arranged at the top of the base 1 and are slidably installed with the top of the base 1. The clamping blocks 2 include a fixing block 3, a positioning block 4 and a locking mechanism 5. At least two first channels 6 are opened on opposite sides of the two fixing blocks 3. The positioning block 4 is installed inside the first channel 6. One end of the positioning block 4 is connected to the inner wall of the first channel 6 by a spring 7, and the positioning block 4 moves along the center line of the first channel 6. The locking mechanism 5 is installed on the top of the fixing block 3.

[0025] When using, Figure 3As shown, two clamping blocks 2 are slid, a slide groove 16 is provided at the top of the base 1, and two adjusting screws 17 are symmetrically installed inside the slide groove 16. A mounting block 18 is installed at the bottom of the fixed block 3, and a sleeve 19 is symmetrically installed at the bottom of the mounting block 18. The sleeve 19 is sleeved with the adjusting screw 17, and an adjusting nut 20 is installed on one side of the sleeve 19. The adjusting nut 20 is threadedly connected with the adjusting screw 17 on one side. The adjusting nuts 20 at the bottom ends of the two mounting blocks 18 are staggered and respectively threadedly connected with two different adjusting screws 17. By rotating the two adjusting screws 17, the corresponding clamping blocks 2 can be controlled to move respectively, so that the clamping blocks 2 move to a suitable position, and the two clamping blocks 2 are clamped and fixed with the processing parts, and the operation is simple. When the clamping block 2 contacts the part, the positioning block 4 contacts the surface of the part, and according to the concave and convex conditions of the surface of the part, the positioning block 4 is squeezed to make it move inside the first channel 6, and a covering net is automatically formed according to the outer surface of the part to contact with different positions of the part, increase the contact area, improve the stability of the part fixation, and avoid sliding to affect the processing effect.

[0026] Preferably, Figure 4 As shown, the shape of the positioning block 4 toward the outer end is rectangular or arc-shaped. A suitable positioning block 4 can be selected for fixing work according to the outer surface conditions of the part to be processed, thereby improving the scope of application.

[0027] like Figure 5-6 As shown, the locking mechanism 5 includes a top plate 9 and a locking block 10. The bottom end of the top plate 9 is equipped with a locking block 10 in conjunction with the positioning block 4. The top end of the fixing block 3 is equipped with a second channel 8 in conjunction with the locking block 10, and the second channel 8 is communicated with the first channel 6. The locking block 10 is inserted into the second channel 8, and the bottom end of the locking block 10 is located directly above the corresponding positioning block 4. The locking block 10 is moved inside the second channel 8 to contact the positioning block 4, thereby fixing the position of the positioning block 4. The bottom end of the locking block 10 and the top end of the positioning block 4 are both provided with an anti-skid groove 15. The bottom end of the locking block 10 is meshed and connected with the anti-skid groove 15 at the top end of the positioning block 4 through the anti-skid groove 15, so that The locking block 10 is in more precise contact with the positioning block 4 to avoid movement of the positioning block 4 during operation, which would affect the clamping effect. The top of the fixing block 3 is provided with guide grooves 11 on both sides of the second channel 8, and guide blocks 12 are installed on both sides of the bottom of the top plate 9, and the guide blocks 12 are inserted into the guide grooves 11 and move along the guide grooves 11, so that the locking mechanism 5 can move stably above the fixing block. A fixing screw 14 is installed at the center of the bottom of the top plate 9, and a screw hole 13 is provided at the center of the top of the fixing block 3. The fixing screw 14 is threadedly connected to the screw hole 13. By rotating the fixing screw 14, the locking mechanism 5 can be controlled to rise and fall, and the operation is simple.

[0028] Preferably, one end of the fixed screw 14 and the adjusting screw 17 are sleeved with a rotating wheel 21, so that the user can rotate the fixed screw 14 and the adjusting screw 17 to perform corresponding work.

[0029] Embodiment 2: The difference from the above is that the rotation of the fixed screw 14 and the adjusting screw 17 is electrically controlled. Specifically, the ends of the fixed screw 14 and the adjusting screw 17 are sleeved with pulleys, and the pulleys are rotatably connected to the output shafts of different motors through linkage belts. When the user adjusts the device, the rotation of the motor can be controlled to drive the corresponding pulley to rotate, thereby driving the opposite fixed screw 14 or adjusting screw 17 to rotate, thereby achieving locking, unlocking or adjusting the clamp 2. The operation is simple, and the use is more convenient and reliable.
