Description

Technical Field

[0001] This utility model relates to the technical field of dust cover processing, and in particular to a deburring device for dust cover processing. Background Technology

[0002] During the processing of dust covers, burrs are often inevitably generated on their edges or surfaces. These burrs not only affect the appearance quality of the dust cover, but may also scratch other parts during assembly. Therefore, a deburring device for processing dust covers is needed.

[0003] A deburring device for processing dust covers, authorized by announcement number CN221496828U, includes a mounting table. An L-shaped support rod is fixedly mounted on one side of the upper surface of the mounting table, and a deburring tool is mounted on the L-shaped support rod. This deburring device for processing dust covers has advantages such as adaptability to dust covers of different sizes, saving manpower, and improving production efficiency. The user controls the rotation of a reciprocating motor, which, in conjunction with a rubber abutment, presses the plastic dust cover, and the deburring tool removes burrs from the edge of the plastic dust cover. When different sizes of plastic dust covers need to be deburred, the height of the deburring tool is adjusted by rotating a rotating button to slide the slide table, and the left and right distance of the deburring tool is adjusted by rotating a threaded screw. Compared with traditional manual deburring, this device can adjust the distance of the deburring tool to adapt to the edges of plastic dust covers of different sizes, greatly improving production efficiency. Moreover, it is simple to operate and has wide adaptability.

[0004] However, in the aforementioned deburring device for processing dust covers, the rubber abutment is connected to the slider via a deep groove ball bearing and is used to press the dust cover. However, due to the rotation of the workpiece, especially thin-walled parts, radial displacement is easily generated due to centrifugal force, causing deburring position deviation.

[0005] To address the aforementioned problems, a deburring device for processing dust covers is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a deburring device for processing dust covers, so as to solve the problem of the existing deburring devices for processing dust covers mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a deburring device for processing dust covers, comprising a processing table, a height adjustment component provided on the top of the processing table, a positioning component provided in the middle of the top of the processing table, a deburring component provided on the top of the height adjustment component, and the deburring component being positioned above the positioning component.

[0008] The deburring assembly includes a top plate mounted on top of the height adjustment assembly. The bottom of the top plate is provided with a movable plate, which moves in a circle around the center of the top plate. A slider is slidably connected to the inner wall of the movable plate. An L-shaped post passes through the inner wall of the slider. A threaded rod passes through the inner wall of the slider and is threadedly connected to the slider. Two sets of guide posts are installed parallel to each other at both ends of the threaded rod, and the guide posts pass through the slider and are slidably connected to the slider.

[0009] Preferably, the deburring assembly further includes a guide groove formed in the bottom wall of the top plate, a guide rod is fixedly installed on one side of the top of the movable plate, and the guide rod is embedded in the inner wall of the guide groove and slidably connected with the guide groove. A limit block is fixedly installed at the bottom of the movable plate, and the limit block is located on one side of the slider and slidably connected with the L-shaped column. A deburring tool is installed at the bottom end of the L-shaped column.

[0010] Preferably, the threaded rod and the guide post are both located on the inner wall of the movable plate, and the L-shaped post is located below the movable plate.

[0011] Preferably, the height adjustment assembly includes mounting bases installed on both sides of the top of the processing table. The bottom wall of the mounting base is provided with a first electric push rod. Both ends of the mounting base are provided with sliding grooves. The inner wall of the mounting base is slidably connected to a top mounting frame, and the bottom of the top mounting frame is connected to the connecting end of the first electric push rod. Both sides of the top mounting frame are provided with two sets of sliding columns, and the sliding columns pass through the sliding grooves and are slidably connected to the sliding grooves.

[0012] Preferably, the top plate is mounted on the bottom of the top mounting bracket.

[0013] Preferably, the positioning assembly includes a bottom positioning seat installed on the top of the processing table, with positioning blocks on both sides of the bottom positioning seat. A rubber block is glued to the side of the positioning block closest to the center of the bottom positioning seat, and a second electric push rod is installed on the side of the positioning block away from the center of the bottom positioning seat. The connecting end of the second electric push rod passes through the bottom positioning seat and connects with the positioning block.

[0014] Preferably, the second electric actuator is mounted on both sides of the bottom positioning seat.

[0015] Preferably, the L-shaped post is positioned above the bottom positioning seat, and the deburring tool is positioned above and to the side of the bottom positioning seat.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The deburring assembly allows manual adjustment of the radial position of the deburring tool via a threaded rod. Combined with a slider, guide post, and other structures, it can be aligned with different inner diameters or burr positions without replacing the entire tool. The drive motor drives the tool to make a circular motion, and the movable plate slides in the guide groove via a guide rod, ensuring that the rotation trajectory is controllable. Compared with workpiece rotation, the active movement of the tool reduces the accumulation of errors caused by workpiece rotation, resulting in good cutting consistency.

[0018] 2. The dust cover is clamped and fixed by the bottom positioning seat, positioning block and rubber block, and remains stationary throughout the process to prevent the workpiece from being displaced or deformed due to the centrifugal force of rotation. It is especially suitable for dust covers made of thin-walled and fragile materials.

[0019] 3. The first electric push rod drives the top mounting bracket to slide up and down along the slide groove through the telescopic action. With the guidance of the sliding column, the vertical height of the deburring assembly can be adjusted to adapt to dust covers of different thicknesses. Attached Figure Description

[0026] 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.

[0027] Example

[0028] like Figure 1 , 3 As shown in Figure 4, the assembly includes a processing table 1, a height adjustment component 2 on the top of the processing table 1, a positioning component 3 in the middle of the top of the processing table 1, a deburring component 4 on the top of the height adjustment component 2, and the deburring component 4 above the positioning component 3. The deburring component 4 includes a top plate 401 mounted on the top of the height adjustment component 2, a movable plate 402 at the bottom of the top plate 401, and the movable plate 402 revolves in a circular motion around the center of the top plate 401. A slider 403 is slidably connected to the inner wall of the movable plate 402, an L-shaped post 404 passes through the inner wall of the slider 403, and a threaded rod 405 passes through the inner wall of the slider 403. 5 is threadedly connected to slider 403. Two sets of guide posts 406 are installed parallel to each other at both ends of the threaded rod 405. The guide posts 406 pass through slider 403 and are slidably connected to slider 403. The deburring assembly 4 also includes a guide groove 407 opened in the bottom wall of top plate 401. A guide rod 408 is fixedly installed on one side of the top of movable plate 402. The guide rod 408 is embedded in the inner wall of guide groove 407 and is slidably connected to guide groove 407. A limit block 409 is fixedly installed at the bottom of movable plate 402. The limit block 409 is located on one side of slider 403 and is slidably connected to L-shaped post 404. A deburring tool 410 is installed at the bottom end of L-shaped post 404.

[0029] It should be noted that in this embodiment, during processing, the threaded rod 405 is manually adjusted according to the inner diameter of the dust cover or the position of the burr (the adjusting end of the threaded rod 405 has a self-locking function, which is existing technology and will not be described). The slider 403 slides along the guide post 406 through the threaded transmission. Simultaneously, the slider 403 drives the L-shaped post 404 to slide inside the limit block 409, thereby adjusting the radial distance of the deburring tool 410 so that it is aligned with the edge to be processed. The top of the top mounting bracket 204 is equipped with a drive motor, and the output shaft of the drive motor passes through the top mounting bracket 204 and is connected to the connecting movable plate 402. After the adjustment is completed, the drive motor is started. The drive motor drives the movable plate 402 to rotate, and the deburring tool 410 moves in a circular motion with the movable plate 402. The movable plate 402 slides in the guide groove 407 of the top plate 401 through the guide rod 408 to ensure a stable rotation trajectory and to continuously cut the edge of the dust cover, thereby performing the deburring work of the dust cover.

[0030] Among them, such as Figure 2As shown, the height adjustment component 2 includes mounting bases 201 installed on both sides of the top of the processing table 1. The bottom wall of the mounting base 201 is provided with a first electric push rod 202. Both ends of the mounting base 201 are provided with sliding grooves 203. The inner wall of the mounting base 201 is slidably connected to a top mounting frame 204, and the bottom of the top mounting frame 204 is connected to the connecting end of the first electric push rod 202. Both sides of the top mounting frame 204 are provided with two sets of sliding columns 205, and the sliding columns 205 pass through the sliding grooves 203 and are slidably connected to the sliding grooves 203. Before processing, according to the thickness of the dust cover, the first electric push rod 202 is controlled to extend or retract, thereby driving the top mounting frame 204 to slide inside the mounting base 201. Simultaneously, the two sets of sliding columns 205 installed on both sides of the top mounting frame 204 slide up and down along the sliding grooves 203, providing guidance and stability for the movement of the top mounting frame 204, and ensuring that the top plate 401 (and deburring component 4) moves vertically to the set height.

[0031] like Figure 5 As shown, the positioning assembly 3 includes a bottom positioning seat 301 installed on the top of the processing table 1. Positioning blocks 302 are provided on both sides of the bottom positioning seat 301. A rubber block 303 is glued to the side of the positioning block 302 near the center of the bottom positioning seat 301. A second electric push rod 304 is installed on the side of the positioning block 302 away from the center of the bottom positioning seat 301, and the connecting end of the second electric push rod 304 passes through the bottom positioning seat 301 and connects with the positioning block 302.

[0032] It should be noted that in this embodiment, the dust cover is first placed in the center of the bottom positioning seat 301, the second electric push rod 304 is extended, and the positioning block 302 is pushed to move towards the center of the bottom positioning seat 301. The rubber block 303 on the inner side of the positioning block 302 contacts the edge of the dust cover, and provides a uniform clamping force by means of elastic deformation to prevent the workpiece from sliding or deforming. At the same time, the second electric push rod 304 maintains a fixed thrust to ensure the stability of the workpiece during the processing.

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual appendix Figure 1-5 First, place the dust cover in the center of the bottom positioning seat 301, then activate the extension of the second electric push rod 304 to push the positioning block 302 towards the center of the bottom positioning seat 301. The rubber block 303 on the inner side of the positioning block 302 contacts the edge of the dust cover, using elastic deformation to provide uniform clamping force to prevent the workpiece from sliding or deforming. At the same time, the second electric push rod 304 maintains a fixed thrust to ensure the stability of the workpiece during processing.

[0035] Before processing, according to the thickness of the dust cover, the first electric push rod 202 is controlled to extend or retract, thereby driving the top mounting bracket 204 to slide inside the mounting base 201. Simultaneously, the two sets of sliding columns 205 installed on both sides of the top mounting bracket 204 slide up and down along the sliding groove 203, providing guidance and stability for the movement of the top mounting bracket 204, and ensuring that the top plate 401 (and deburring assembly 4) moves vertically to the set height.

[0036] During processing, the threaded rod 405 is manually adjusted according to the inner diameter of the dust cover or the position of the burr (the adjusting end of the threaded rod 405 has a self-locking function, which is existing technology and will not be described). The slider 403 slides along the guide post 406 through the threaded transmission. Simultaneously, the slider 403 drives the L-shaped post 404 to slide inside the limit block 409, thereby adjusting the radial distance of the deburring tool 410 so that it is aligned with the edge to be processed. The top of the top mounting bracket 204 is equipped with a drive motor, and the output shaft of the drive motor passes through the top mounting bracket 204 and is connected to the connecting movable plate 402. After the adjustment is completed, the drive motor is started, and the drive motor drives the movable plate 402 to rotate. The deburring tool 410 moves in a circular motion with the movable plate 402. The movable plate 402 slides in the guide groove 407 of the top plate 401 through the guide rod 408 to ensure a stable rotation trajectory and to continuously cut the edge of the dust cover, thereby performing the deburring work on the dust cover.
