[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] Combined with Figure 1-4A mechanical parts processing fixture comprises a support base 1, a V-shaped placement groove 3 is arranged in the middle of the top of the support base 1, limit slide grooves 4 are connected on both sides of the support base 1, and limit sliders 5 are provided in the limit slide grooves 4 for limit sliding connection, and the tops of the limit sliders 5 on both sides are connected with a support frame 6. The support frame 6 can slide horizontally on the support base 1 through the limit slide grooves 4 and the limit sliders 5, so that the position can be adjusted according to the length of the cylinder to be processed, and a trapezoidal groove matching the V-shaped placement groove 3 is arranged on the top and bottom of the support frame 6 7. The top of the support frame 6 is provided with a slot 8 connected to the trapezoidal slot 7. A bolt 9 is threadedly connected to one side of the top of the support frame 6 and passes through the bottom of the slot 8. The bolt 9 is located in the slot 8 and is connected with a pressing circle 10. The connection between the bolt 9 and the pressing circle 10 is the outer part of the pressing circle 10. The top of the pressing circle 10 is connected with a handle 11, and the handle 11 can drive the pressing circle 10 and the bolt 9 to rotate according to the center point of the bolt 9. Because when rotating downward, the end of the pressing circle 10 away from the bolt 9 can press the cylinder.

[0019] The support base 1 has a driving cylinder 14 symmetrically connected to the top on both sides. The driving cylinder 14 extends to the inside of the V-shaped placement groove 3. The exposed position is suitable for most cylindrical parts. If the diameter of the cylindrical part is too small, it will not need to rotate too much during processing. The outer surface of the driving cylinder 14 needs to adopt high friction to prevent the cylindrical part from rotating when it does not need to rotate. One side of the support base 1 is connected to a driving box 15 for driving the driving cylinders 14 on both sides to rotate. The driving box 15 is connected to a driving cylinder on one side. The column 14 is directly connected to a servo motor 17, and the drive box 15 is provided with a transmission cavity 16. The drive cylinders 14 on both sides extend into the transmission cavity 16 and are connected with a transmission sprocket 18. The drive sprockets 18 on both sides are directly connected with a transmission chain 19. The drive box 15 is connected with a controller 20 and a battery 21 that cooperate with the servo motor 17. The controller 20 and the battery 21 can control the start and speed of the servo motor 17, thereby driving the rotation of the drive cylinders 14 on both sides, thereby driving the cylindrical parts to perform stable rotation operations.

[0020] A plurality of circular grooves 12 are provided in the middle of the bottom of the pressing circle 10, and balls 13 are embedded in the circular grooves 12. The balls 13 extend to the outside, and the cylinders can be driven laterally to cooperate with the driving cylinder 14 to rotate.

[0021] The bottom of the support base 1 is connected with a fixed support floor 2, and the limit sliders 5 on both sides are connected with fastening bolts 22. The fixed support base 2 can be installed according to needs, which can increase the contact area and increase the friction force. The position of the limit slider 5 and the support frame 6 can be positioned and stabilized by fastening the bolts 22.

[0022] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
