Description

Technical Field

[0001] This utility model relates to the field of honing tube outer wall polishing technology, specifically to an adaptive fixture for honing tube outer wall polishing. Background Technology

[0002] Honed tube outer wall polishing is a key technology in the field of precision machining, and its background is closely related to industrial needs, technological bottlenecks, and development trends. In industrial applications, honed tubes are commonly used in hydraulic systems, aerospace, and high-end equipment manufacturing. The surface quality of their outer walls directly affects the sealing performance, corrosion resistance, and fluid transmission efficiency of the tubes.

[0003] When polishing the outer wall of a honing tube, it is usually necessary to clamp and position both ends of the tube body. In the existing technology, the tube clamping tools usually require manual adjustment by the operator according to the size of the tube, which is complicated and requires the operator to align the center position, and cannot quickly limit the position of the tube. Utility Model Content

[0004] This invention provides an adaptive fixture for polishing the outer wall of a honing tube, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] An embodiment of this utility model provides an adaptive fixture for polishing the outer wall of a honing tube, comprising:

[0007] Base plate;

[0008] The slide rail is fixedly connected to the surface of the base plate to help move the equipment on the surface;

[0009] The auxiliary plate is fixedly connected to the surface of the base plate and is used to help the pipes that need to be polished to be aligned at the center position.

[0010] A clamping device, mounted on the surface of the slide rail, is used to adaptively clamp the auxiliary pipe.

[0011] A collection device, installed on the surface of the slide rail, is used to guide and collect debris generated during the polishing process.

[0012] Furthermore, the clamping device includes a movable frame, which is slidably connected to the surface of the slide rail. A motor is fixedly connected to the surface of the movable frame, and a screw is rotatably connected to the surface of the movable frame. A drive plate is fixedly connected to the output end of the motor, and a connecting plate is rotatably connected to the surface of the drive plate. The connecting plate has a "T"-shaped cross-section and three grooves on its surface. Limiting rods are slidably connected to the surfaces of the three grooves. A support plate is fixedly connected to the surface of the movable frame, and a limiting plate is slidably connected to the arc surface of the support plate. Three guide holes are opened on the surface of the limiting plate, and the limiting rods are slidably connected to the guide holes. A guide plate is fixedly connected to the end of the limiting rods away from the limiting plate. A torsion spring is sleeved on the surface of the connecting plate, and both ends of the torsion spring are fixedly connected to the connecting plate and the drive plate, respectively. A rotating ring is rotatably connected to the surface of the drive plate, and a first screw is threadedly connected to the surface of the rotating ring. A connecting seat is fixedly connected to the surface of the connecting plate, and the first screw is threadedly connected to the connecting seat.

[0013] The above technical solution involves passing the pipe to be polished through the auxiliary plate, then pressing the pipe against the surface of the guide plate, and guiding it into the middle position of the three limiting rods. With the help of the torsion spring, a preliminary limiting effect can be achieved. Then, the connecting seat and the rotating ring are connected together by the first screw to fix it, thus achieving self-adaptive clamping of the pipe.

[0014] Furthermore, the surface of the limiting rod is bonded with an anti-slip sleeve, which is made of rubber.

[0015] Through the above technical solution, the anti-slip sleeve can increase the friction between itself and the pipeline, thereby improving the stability when limiting the pipeline.

[0016] Furthermore, the surface of the movable frame is rotatably connected to four ball bearings, all of which are slidably connected to the surface of the slide rail.

[0017] Using the above technical solution, workers can move the moving frame according to the pipe length. At this time, the ball bearings can slide against the upper surface of the slide rail, thereby reducing the friction between the moving frame and the slide rail and improving the smoothness of the moving frame movement.

[0018] Furthermore, the surface of the auxiliary plate is rotatably connected to an internally threaded sleeve, and the inner wall of the internally threaded sleeve is threadedly connected to a second screw. The second screw is threadedly connected to the auxiliary plate, and the end of the second screw away from the internally threaded sleeve is rotatably connected to a placement platform. The lower surface of the placement platform is fixedly connected to two round rods, and both round rods are slidably connected to the auxiliary plate.

[0019] The above technical solution allows the second screw to rotate by rotating the internal threaded sleeve, thereby adjusting the height of the placement platform. This allows the two ends of the pipe to be raised to a horizontal position, facilitating the motor's drive to rotate the pipe and reducing the burden on the motor.

[0020] Furthermore, the collecting device includes a placement rack, which is fixedly connected to the upper surface of the slide rail. A collecting frame is slidably connected to the inner wall of the placement rack, and an arc plate is fixedly connected to the surface of the placement rack. The surface of the arc plate has a circular hole.

[0021] With the above technical solution, when polishing, the polishing equipment is moved to the base plate and side wall. During the movement of the moving frame, the polishing equipment can polish the outer wall of the pipe. The polishing debris will be guided into the inside of the collection box by the arc plate, preventing dust from scattering on the ground and making it inconvenient to clean.

[0022] Furthermore, the inner wall of the arc plate is slidably connected to two sliding plates, and the surfaces of the two sliding plates are provided with several slots. The surface of the arc plate is fixedly connected to two extension plates, and the surfaces of the two extension plates are fixedly connected to locking rods, which engage with the slots.

[0023] Through the above technical solution, the slide plate, together with the snap-fit ​​rod, can contact the lower end of the polishing position on one side, which improves the collection effect of the polishing debris.

[0024] Furthermore, a pull plate is slidably connected to the surface of the arc plate, and the surface of the pull plate is provided with a pull hole.

[0025] With the above technical solution, when replacing the collection box, the sliding plate can block the round hole to prevent debris from falling to the ground through the round hole.

[0026] The above-described solution of this utility model has at least the following beneficial effects:

[0027] 1. This utility model, by setting a clamping device, can self-adaptively clamp one end of the pipe when it is placed, which facilitates the polishing of the outer wall of the pipe, reduces the need for workers to perform too many operations, increases the convenience of the pipe processing process, and thus improves work efficiency.

[0028] 2. This utility model, by setting up a collection device, can collect as much of the polishing debris as possible during pipe polishing, preventing the debris from scattering on the ground, making it easier for workers to collect and clean up the debris, thereby reducing labor intensity.

[0036] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0037] like Figures 1 to 5 As shown, an embodiment of this utility model provides an adaptive fixture for polishing the outer wall of a honing tube, comprising:

[0038] Base plate 1; slide rail 2, fixedly connected to the surface of base plate 1, used to help the equipment on the surface move; auxiliary plate 3, fixedly connected to the surface of base plate 1, used to help the pipes that need to be polished to be aligned at the center position; clamping device 4, set on the surface of slide rail 2, used to adaptively clamp the auxiliary pipes; collection device 5, set on the surface of slide rail 2, used to guide and collect the debris during the polishing process.

[0039] like Figures 1 to 4 As shown, the clamping device 4 includes a movable frame 401, which is slidably connected to the surface of the slide rail 2. A motor 402 is fixedly connected to the surface of the movable frame 401, and a screw 403 is rotatably connected to the surface of the movable frame 401. A drive disk 405 is fixedly connected to the output end of the motor 402, and a connecting disk 408 is rotatably connected to the surface of the drive disk 405. The cross-section of the connecting disk 408 is "T" shaped, and three sliding grooves 413 are opened on the surface of the connecting disk 408. Limit rods 412 are slidably connected to the surfaces of the three sliding grooves 413.

[0040] A support plate 420 is fixedly connected to the surface of the movable frame 401. A limit plate 411 is slidably connected to the arc surface of the support plate 420. Three guide holes 421 are opened on the surface of the limit plate 411. A limit rod 412 is slidably connected to the guide holes 421. A guide plate 415 is fixedly connected to the end of the limit rod 412 away from the limit plate 411. A torsion spring 410 is sleeved on the surface of the connecting plate 408. The two ends of the torsion spring 410 are fixedly connected to the connecting plate 408 and the driving plate 405 respectively. A rotating ring 406 is rotatably connected to the surface of the driving plate 405. A first screw 407 is threadedly connected to the surface of the rotating ring 406.

[0041] A connecting seat 409 is fixedly connected to the surface of the connecting plate 408. The first screw 407 is threadedly connected to the connecting seat 409. The pipe to be polished passes through the auxiliary plate 3 and then abuts against the surface of the guide plate 415. It is then guided by the guide plate 415 into the middle position of the three limiting rods 412. With the help of the torsion spring 410, a preliminary limiting effect can be achieved. Then, the connecting seat 409 and the rotating ring 406 are connected together by the first screw 407 to fix it. At this time, the self-adaptive clamping of the pipe can be achieved.

[0042] The surface of the limiting rod 412 is bonded with an anti-slip sleeve 414, which is made of rubber. The anti-slip sleeve 414 can increase the friction between the rod and the pipe, thereby improving the stability when limiting the pipe. The surface of the moving frame 401 is rotatably connected with four balls 404. All four balls 404 are slidably connected to the surface of the slide rail 2. Depending on the length of the pipe, the operator will move the moving frame 401. At this time, the balls 404 can slide in contact with the upper surface of the slide rail 2, thereby reducing the friction between the moving frame 401 and the slide rail 2, thereby improving the smoothness of the moving frame 401 when moving.

[0043] An internally threaded sleeve 416 is rotatably connected to the surface of the auxiliary plate 3. A second screw 417 is threadedly connected to the inner wall of the internally threaded sleeve 416. The second screw 417 is threadedly connected to the auxiliary plate 3. A placement platform 419 is rotatably connected to the end of the second screw 417 away from the internally threaded sleeve 416. Two round rods 418 are fixedly connected to the lower surface of the placement platform 419. Both round rods 418 are slidably connected to the auxiliary plate 3. By rotating the internally threaded sleeve 416, the second screw 417 can be driven to rotate, thereby adjusting the height of the placement platform 419. This allows the two ends of the pipe to be raised to a horizontal state in conjunction with the placement platform 419, facilitating the rotation of the pipe by the motor 402 and reducing the burden on the motor 402.

[0044] In this embodiment of the utility model (working principle), when it is necessary to polish the outer wall of the pipe, the movable frame 401 is slid towards the auxiliary plate 3. At this time, the ball bearing 404 contacts the surface of the slide rail 2, increasing the smoothness of movement. Further rotating the screw 403 allows the screw 403 to abut against the surface of the slide rail 2, thus limiting the movable frame 401. Then the pipe passes through the position of the auxiliary plate 3, and the outer wall is placed on the surface of the placement platform 419. At this time, the operator can push the pipe towards the guide plate 415.

[0045] When one end of the pipe contacts the guide plate 415, the guide plate 415 guides the pipe to the middle position of the three limit rods 412. At the same time, the three limit rods 412 slide and adapt on the guide hole 421 and the slide groove 413 according to the size of the pipe. In addition, the torsion spring 410 can simply limit the pipe. Then, the rotating ring 406 is rotated so that the first screw 407 is threadedly connected to the connecting seat 409. At this time, the limit rod 412 is stably limited and will not move. The self-adaptive clamping of one end of the pipe is completed. Then, the operator can rotate the inner threaded sleeve 416 so that the other end of the pipe driven by the placement platform 419 is at the same height as the clamped end, which can reduce the burden on the motor 402 when driving the pipe to rotate.

[0046] like Figures 1 to 2 as well as Figure 5 As shown, the collection device 5 includes a placement frame 51, which is fixedly connected to the upper surface of the slide rail 2. A collection frame 52 is slidably connected to the inner wall of the placement frame 51. An arc plate 53 is fixedly connected to the surface of the placement frame 51. A circular hole 54 is opened on the surface of the arc plate 53. When polishing, the polishing equipment is moved to the base plate 1 and the side wall is driven. During the movement of the moving frame 401, the polishing equipment can polish the outer wall of the pipe. The polishing debris will be guided into the inside of the collection frame 52 through the arc plate 53, preventing dust from falling on the ground and making it inconvenient to clean.

[0047] Two sliding plates 56 are slidably connected to the inner wall of the arc plate 53. Several slots 57 are opened on the surface of the two sliding plates 56. Two extension plates 59 are fixedly connected to the surface of the arc plate 53. A locking rod 58 is fixedly connected to the surface of the two extension plates 59. The locking rod 58 is locked with the slot 57. The sliding plate 56, in conjunction with the locking rod 58, can contact the lower end of the polishing position on one side, which improves the collection effect of polishing debris. A pull plate 55 is slidably connected to the surface of the arc plate 53. The surface of the pull plate 55 is opened with a pull hole. When replacing the collection frame 52, the pull plate 55 can be slidably blocked to prevent debris from falling to the ground from the round hole 54.

[0048] In this embodiment of the invention, during polishing, the sliding plate 56 is slid so that one side of the sliding plate 56 is close to the contact point between the polishing equipment and the pipe. At the same time, the locking rod 58 can be locked inside the locking groove 57 to limit the sliding plate 56, making it difficult for the sliding plate 56 to slide again. At this time, the sliding plate 56 and the arc plate 53 can guide the polishing debris to the round hole 54 and drop it into the collection frame 52 for collection. When replacing the collection frame 52, the worker can push the pull plate 55 to the round hole 54 to seal the round hole 54. After the collection frame 52 is replaced, the pull plate 55 can be pulled out to start collecting debris again, effectively preventing debris from scattering on the ground and reducing the labor intensity of the workers.

[0049] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
