Abstract
Description
Technical Field
[0001] This utility model relates to the field of screw polishing technology, specifically a precision screw polishing device. Background Technology
[0002] Screw polishing aims to reduce screw surface roughness, minimize machining defects and residual stress, and ensure that the screw surface quality meets design and usage requirements. Existing polishing devices use a high-speed abrasive jet to polish the screw's outer surface. The screw moves and rotates to allow the high-speed abrasive jet to effectively polish the outer surface. However, the screw's movement and rotation are controlled by an electric actuator and a motor, respectively. During maintenance, both the electric actuator and the motor need to be maintained and calibrated, making maintenance difficult and unsuitable for current usage requirements. Utility Model Content

Detailed Implementation
[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0016] like Figure 1-3 As shown, a precision screw polishing device includes a base 1, a fixing rod 2 mounted on the base 1, a straight rack 3 mounted on one side of the base 1, and a placement table 4 located on the base 1 and slidably connected to the fixing rod 2. A side plate 5 is mounted on one side of the placement table 4, a fixing plate 6 is mounted at one end of the side plate 5, a first pad 7 is rotatably connected to one side of the fixing plate 6, a fixing ring 8 is mounted at one end of the placement table 4, a screw 9 is located between the fixing plate 6 and the fixing ring 8, and a sleeve 1 is rotatably connected inside the fixing ring 8. 0. The sleeve 10 is internally threaded with bolts 11. A rotating shaft 12 is provided on the side plate 5. One end of the rotating shaft 12 and the outer surface of the sleeve 10 are provided with meshing bevel gears 13. The other end of the rotating shaft 12 is provided with a spur gear 14, which meshes with the spur rack 3. A mounting bracket 15 is provided on one side of the side plate 5. A motor 16 for driving the rotating shaft 12 to rotate is provided inside the mounting bracket 15. A support frame 17 is provided on one side of the base 1. An abrasive spraying module 18 is provided on the upper end of the support frame 17.
[0017] Before polishing the screw 9, it is necessary to fix the screw 9 first. When fixing the screw 9, first abut one end of the screw 9 against the first pad 7, and then rotate the bolt 11. The motor 16 has a self-locking function, which will restrict the rotation of the spur gear 14, the rotating shaft 12 and the bevel gear 13. Therefore, when the bolt 11 rotates, the sleeve 10 will not rotate with the bolt 11. The bolt 11 can be screwed into the sleeve 10. The front end of the bolt 11 abuts against the screw 9. By tightening the bolt 11, the screw 9 is clamped and fixed between the bolt 11 and the first pad 7, thus completing the placement of the screw 9.
[0018] When polishing the screw 9, the motor 16 is started first. The motor 16 drives the rotating shaft 12 to rotate through its output end, and drives the spur gear 14 and bevel gear 13 on the rotating shaft 12 to rotate. The engagement of the spur gear 14 and the rack 3 allows the placement platform 4 to move along the fixed rod 2 on the base 1. Through the meshing of the two bevel gears 13, the sleeve 10 can be driven to rotate. Since the first pad 7 and the fixed plate 6 are rotatably connected, the sleeve 10 can drive the screw 9 between the bolt 11 and the first pad 7 to rotate when it rotates. Thus, the screw 9 can rotate while moving linearly. The abrasive spraying module 18 is the spraying part of the spray polishing machine. When the motor 16 is started, the abrasive spraying module 18 sprays high-speed abrasive particles onto the outer surface of the screw 9 to achieve the polishing effect. At the same time, the whole device is installed in the working chamber of the spray polishing machine. By controlling the forward and reverse directions of the motor 16, the individual screw 9 can be moved back and forth to achieve a good polishing effect.
[0019] Furthermore, the placement platform 4 is provided with an arc-shaped placement groove 19, which is connected to the placement platform 4 by a vertical rod 20. When installing the screw 9, it is only necessary to place the screw 9 into the placement groove 19. By controlling the screw 11 to screw in, the screw 9 can be clamped and fixed between the first pad 7 and the bolt 11. After the screw 9 is clamped and fixed, the rotation center line of the screw 9 coincides with the arc center of the placement groove 19, and the vertical rod 20 is compressible. When the screw 9 is placed into the placement groove 19, the weight of the screw 9 will not cause the vertical rod 20 to deform and affect the accurate placement of the screw 9. This ensures that when the screw 9 rotates, the placement groove 19 will not affect the rotation of the screw 9. At the same time, the vertical rod 20 can be replaced by a spring.
[0020] Furthermore, the placement groove 19 is made of nylon plastic to reduce friction between the screw 9 and the placement groove 19.
[0021] Furthermore, the end of the bolt 11 is provided with a compressible second pad 21. When clamping and fixing the screw 9, the stability of clamping and fixing the screw 9 is increased by compressing the second pad 21.
[0022] Furthermore, the rack 3 is connected to the base 1 by a bent plate 22. The bent plate 22 can increase the distance between the rack 3 and the side plate 5, thus avoiding friction between the side plate 5 and the rack 3 when the side plate 5 moves along the fixed rod 2.
[0023] When in use, the device can provide power for the movement and rotation of the screw 9 simultaneously through a single motor 16, thereby reducing the number of devices required to provide power. Due to the reduction in the number of power supply devices, maintenance and calibration time can be reduced during downtime maintenance, making maintenance easier and more convenient to use.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
