Description

Technical Field

[0001] This utility model relates to the field of bushing processing technology, specifically a bushing processing positioning device. Background Technology

[0002] A bushing is a mechanical part that is typically used to reduce friction and support rotating shafts. Bushings are usually made of metal or plastic and are widely used in machines and equipment such as automobiles, airplanes, industrial robots, and household appliances.

[0003] For the machining of bushings, the bushing to be machined is usually fixed by a positioning fixture before machining. However, for the machining of graphite bushings, not only is precise positioning and fixing by a positioning fixture required, but also the treatment of graphite powder generated during the machining process must be taken into account to prevent the graphite powder from coming into contact with external devices and causing irreversible damage. Utility Model Content

[0004] The purpose of this invention is to provide a bushing machining positioning device to solve the problem of collecting graphite powder during the machining and positioning of graphite bushings mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bushing processing positioning device, comprising a fixed frame, partitions fixedly connected to the top of the fixed frame around its perimeter, a protective shell fixedly connected to the bottom of the fixed frame, a drive assembly fixedly connected to the inner side of the protective shell, a clamping assembly fixedly connected to the middle of the partitions, a glass window fixedly connected to the front of the partitions, and a dust collection assembly fixedly connected to one side of the fixed frame. The drive assembly drives the clamping assembly to work, the dust collection assembly can adsorb the powder generated during the processing of the graphite bushing, and the protective shell can prevent dust from flying directly away from the device and affecting the outside world.

[0006] Preferably, the drive assembly includes a motor base, a stepper motor is fixedly connected to the top of the motor base, a gearbox is fixedly connected to the output end of the stepper motor, a transmission rod is meshed on the inner side of the gearbox, and the bottom end of the transmission rod is a rack and pinion structure. The stepper motor controls the lifting and lowering of the transmission rod, which can make the lifting and lowering more stable. The gearbox can limit the lifting and lowering of the transmission rod to prevent the transmission rod from moving during operation.

[0007] Preferably, the clamp assembly includes a fixed base, the fixed base has multiple sliding grooves in the middle, and two fixed blocks are slidably connected to the inner side of each of the multiple sliding grooves. One end of each of the two fixed blocks is rotatably connected to a linkage block, and a limiting component is provided at one end between the two linkage blocks that are directly opposite each other.

[0008] Preferably, the limiting component includes a connecting block, one end of which is fixedly connected to a fixing plate, one side of which is fixedly connected to an anti-slip pad, and the other end of which is rotatably connected to one end of a linkage block. The connecting block pushes the fixing plate to move, so that the anti-slip pad is in close contact with the inner wall of the bushing.

[0009] Preferably, the anti-slip pad is made of rubber material, and the plurality of fixing blocks are fixedly connected to the outside of the transmission rod. The bottom end of the transmission rod is threaded. The rubber anti-slip pad increases friction while deforming to fit more closely to the inner wall of the bushing.

[0010] Preferably, the dust collection assembly includes a collection box, with a vacuum cleaner fixedly connected to the bottom of the collection box, a movable plate movably connected to one side of the collection box, a connecting pipe fixedly connected to the top of the collection box, a collection tray fixedly connected to one end of the connecting pipe, and a suction pipe fixedly connected to the other end of the connecting pipe. The collection box has a filtering function that can filter and collect the dust collected by the collection tray and the suction pipe, preventing dust from flying around.

[0011] Preferably, the bottom end of the collection tray is fixedly connected to the surface of the top of the fixing frame, one side of the suction pipe is fixedly connected to the inside of the partition, and one side of the protective shell is spirally connected with multiple nuts. The protective shell is fixedly connected to a maintenance plate through multiple nuts, and the inside of the protective shell can be quickly repaired and replaced through the maintenance plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The stepper motor drives the gearbox to control the lifting and lowering of the transmission rod. The fixed block on the surface of the transmission rod drives the linkage block to rotate, causing the fixed plate to expand outward. The expansion of multiple fixed plates makes the anti-slip pad on one side of the fixed plate tightly fit with the inner side of the bushing, thus fixing the bushing and facilitating the processing of the outer surface of the bushing. At the same time, the anti-slip pad fixedly connected to the surface of the fixed plate can prevent wear on the inner wall surface of the bushing during the fixing process, avoiding changes in dimensional accuracy during processing. The operation of the vacuum cleaner collects the graphite powder generated during the processing of the graphite bushing through the collection tray and the vacuum pipe. The powder is then transferred into the collection box through the connecting pipe. After being filtered by the collection box, the graphite powder is collected in the collection box. The movable plate can remove the graphite powder for reuse, preventing graphite powder from flying into electronic components during processing and causing short circuit damage. At the same time, the reuse of graphite powder saves processing costs. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-5 This utility model provides a bushing processing positioning device, including a fixed frame 1, a partition 2 fixedly connected to the top of the fixed frame 1 around the perimeter, a protective shell 4 fixedly connected to the bottom of the fixed frame 1, a drive assembly fixedly connected to the inner side of the protective shell 4, a clamping assembly fixedly connected to the middle of the partition 2, a glass window 3 fixedly connected to the front of the partition 2, and a dust collection assembly fixedly connected to one side of the fixed frame 1.

[0021] Furthermore, the drive assembly includes a motor base 19, a stepper motor 8 is fixedly connected to the top of the motor base 19, a gearbox 18 is fixedly connected to the output end of the stepper motor 8, a transmission rod 7 is meshed on the inner side of the gearbox 18, and the bottom end of the transmission rod 7 is a rack structure. The stepper motor 8 rotates to drive the gearbox 18 to rotate, causing the transmission rod 7 to rise and fall.

[0022] Furthermore, the clamping assembly includes a fixed base 14, with multiple sliding grooves in the middle of the fixed base 14. Two fixed blocks 15 are slidably connected to the inner side of each of the multiple sliding grooves. A linkage block 16 is rotatably connected to one end of each of the two fixed blocks 15. A limiting component is provided at one end between the two linkage blocks 16 that are directly opposite each other. The fixed blocks 15 slide in the sliding grooves, causing the linkage blocks 16 to rotate, which will push the limiting component.

[0023] Furthermore, the limiting component includes a connecting block, one end of which is fixedly connected to a fixing plate 17, one side of which is fixedly connected to an anti-slip pad 9, and the other end of the connecting block is rotatably connected to one end of a linkage block 16. The connecting block moves to push the fixing plate 17, and the fixing plate 17 pushes the anti-slip pad 9 to move and make it in close contact with the inner wall of the bushing.

[0024] Furthermore, the anti-slip mat 9 is made of rubber material, and multiple fixing blocks 15 are fixedly connected to the outside of the transmission rod 7. The bottom end of the transmission rod 7 is threaded.

[0025] Furthermore, the vacuuming assembly includes a collection box 5, with a vacuum cleaner 6 fixedly connected to the bottom of the collection box 5, a movable plate 13 movably connected to one side of the collection box 5, a connecting pipe 10 fixedly connected to the top of the collection box 5, a collection tray 11 fixedly connected to one end of the connecting pipe 10, and a suction pipe 12 fixedly connected to the other end of the connecting pipe 10. When the vacuum cleaner 6 operates, it drives the dust to enter the collection box 5 for collection through the collection tray 11 and the suction pipe 12.

[0026] Furthermore, the bottom end of the collection tray 11 is fixedly connected to the surface of the top of the mounting bracket 1, one side of the suction pipe 12 is fixedly connected to the inside of the partition 2, and one side of the protective shell 4 is spirally connected with multiple nuts. The protective shell 4 is fixedly connected to the inspection plate 20 by multiple nuts.

[0027] In this embodiment, during the bushing processing operation, the bushing to be processed is first placed on the outside of the anti-slip pad 9. Then, the stepper motor 8 is started. The gearbox 18 has a gear structure installed inside, and its operation drives the gearbox 18 to rotate. Since the gearbox 18 meshes with the rack at the bottom of the transmission rod 7, the operation of the gearbox 18 causes the transmission rod 7 to move downward. During the descent of the transmission rod 7, the fixed block 15 moves downward together. The downward movement of the fixed block 15 drives the linkage block 16 to rotate. When the linkage block 16 rotates, it pushes the connecting block outward. After the connecting block is pushed, it drives the fixing plate 17 to move outward. The movement of the fixing plate 17 synchronously drives the anti-slip pad 9 to extend outward until the anti-slip pad 9 is fully extended. The sliding pad 9 fits tightly against the inner side of the bushing, thus achieving a stable fixation of the bushing. During the bushing processing, the vacuum cleaner 6 is turned on, and the operation of the vacuum cleaner 6 generates suction, which draws the graphite powder generated during the processing from the collection tray 11 into the suction pipe 12. Subsequently, the graphite powder enters the inner side of the collection box 5 through the connecting pipe 10. The collection box 5 is equipped with a filter device, which can filter the incoming graphite powder, so that the graphite powder is intercepted inside the collection box 5. After the bushing processing is completed, simply open the movable plate 13 of the collection box 5 to take out the collected graphite powder for secondary use. Finally, control the stepper motor 8 to rotate in the opposite direction to return all components to their original positions. At this time, the processed bushing can be easily removed.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
