Description

Technical Field

[0001] This utility model relates to the field of aluminum tube processing technology, specifically to a surface polishing device for aluminum tube processing. Background Technology

[0002] Aluminum tubes are a type of non-ferrous metal tube, referring to hollow metal tubular materials made from pure aluminum or aluminum alloys through extrusion processing along their entire longitudinal length.

[0003] In the process of aluminum tube processing, the aluminum tube needs to be polished. For example, the surface polishing device for aluminum tube processing disclosed in the announcement number "CN222696846U" places one end of the aluminum tube in the fixed frame on one side of the fixed rod, and then pushes the moving rod so that the fixed frame on one side of the moving rod fits onto the other end of the aluminum tube. The arc-shaped placement groove supports both ends of the aluminum tube. Then, by rotating the screw, the pressure plate moves down to press and fix both ends of the aluminum tube.

[0004] However, in the actual grinding process, the entire outer surface of the aluminum tube needs to be ground. When the aluminum tube needs to be rotated to adjust its position, the restriction on the aluminum tube can only be lifted first, the aluminum tube can be rotated to adjust the angle, and then it can be fixed again, resulting in low overall processing efficiency. To address this, we propose a surface polishing device for aluminum tube processing. Utility Model Content

[0005] The purpose of this invention is to provide a surface polishing device for aluminum tube processing, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a surface polishing device for aluminum tube processing, comprising a worktable and a polishing device disposed on the top of the worktable, wherein the top of the worktable is provided with a fixing device for fixing the aluminum tube, the fixing device being composed of a sleeve rod, a clamp and a fixing seat, and a limit adjustment device being provided on the fixing device;

[0007] The limit adjustment device includes:

[0008] The limiting toothed ring is used to restrict the sleeve rod when the locking rod is engaged with the limiting toothed ring, so that the sleeve rod cannot rotate.

[0009] The push rod is used to pull the locking rod and the limiting toothed ring out of the engaged state via the connecting rod;

[0010] The support spring provides the force to move the push rod to the left when it is not being resisted.

[0011] Preferably, the bottom of the fixed seat is fixed to the top of the workbench, the sleeve passes through the fixed seat and is rotatably connected to the fixed seat, and the clamp is mounted on the sleeve.

[0012] Preferably, the clamp includes a connecting block rotatably mounted on the inner wall of the sleeve rod. A lead screw is fixed to the right side of the connecting block, and a slide rod is provided on the left side of the connecting block. The slide rod passes through the connecting block and is slidably connected to it. A knob is fixed to the left side of the slide rod, and a return spring is fixed to the left side of the connecting block. The end of the return spring away from the connecting block is fixed to a fixed plate. The slide rod passes through the fixed plate and is fixed to it. The lead screw passes through the slider and is threadedly connected to it. A push rod is hinged to the outer surface of the slider. A through groove is provided on the sleeve rod, through which the push rod passes. The push rod is hinged to the inner support plate at the end away from the slider in the through groove. A support rod is hinged to the side of the inner support plate near the push rod. The end of the support rod away from the inner support plate is hinged to the inside of the through groove. When it is necessary to fix the aluminum tube, the aluminum tube is first placed on the surface of the sleeve rod. The operator manually rotates the knob, which drives the slide rod and the connecting block to rotate. The connecting block then drives the lead screw to rotate together. Because the support rod and the push rod are restricted by the through groove, the slider can only move to the right. Then, by pushing the push rod, the inner support plate is lifted and pressed against the inner wall of the aluminum tube, thus fixing the aluminum tube and preventing it from being fixed on the surface, which would affect the grinding.

[0013] Preferably, the limiting toothed ring is fixed to the left side of the fixing seat. A cavity is formed inside the sleeve rod. The top rod passes through the left side of the sleeve rod and is slidably connected to it. The top rod extends into the cavity. A support spring is fixed to the inner wall of the cavity. The end of the support spring away from the cavity is fixed to the top rod. A connecting rod is hinged to the right side of the top rod. The end of the connecting rod away from the top rod is hinged to a locking rod. The locking rod passes through the sleeve rod and is slidably connected to it. By engaging with the limiting toothed ring, the sleeve rod is restricted, ensuring that when the operator normally controls the rotation of the lead screw to support the inner support plate and fix the aluminum tube, the slider and sleeve rod cannot rotate with the lead screw. When the operator pulls the knob, the slider... When moving to the left, the sliding rod moves to the left along with the fixing plate. The fixing plate no longer contacts the top rod, and the top rod can then move to the left under the action of the support spring. The top rod pulls the locking rod to the side closer to the center of the sleeve rod through the connecting rod, so that the locking rod is no longer engaged with the limiting toothed ring, thus releasing the restriction on the sleeve rod. At this time, when the operator turns the knob to control the lead screw to rotate, the friction between the lead screw and the sliding block, and the action of the push rod, will drive the sleeve rod to rotate together, thereby driving the fixed aluminum tube to rotate together. This facilitates the adjustment of the aluminum tube angle, avoiding the conventional situation where the aluminum tube angle can only be adjusted after the fixing of the aluminum tube is released, effectively improving the overall processing efficiency.

[0014] Preferably, the polishing equipment includes a drive motor, which is fixed on the left side of the worktable. The output shaft of the drive motor passes through the worktable and is fixed to a threaded rod. The threaded rod passes through a movable frame and is threadedly connected to the movable frame. The movable frame is slidably mounted on the top of the worktable. A polishing motor is fixed to the top of the movable frame. A polishing wheel is fixed to the output shaft of the polishing motor. By controlling the rotation of the threaded rod through the drive motor, the movable frame can be moved left and right, thus enabling the polishing motor to move the polishing wheel left and right. The polishing motor drives the polishing wheel to rotate, thereby achieving better polishing of the aluminum tube.

[0015] Compared with the prior art, the present invention provides a surface polishing device for aluminum tube processing, which has the following beneficial effects:

[0016] 1. This surface polishing device for aluminum tube processing, through its fixed and limit adjustment devices, allows for easy adjustment of the aluminum tube's rotation. Simply pull the knob and slide bar to the left; the slide bar moves the fixed plate to the left along with it, freeing the fixed plate from contact with the top rod. The top rod then moves to the left under the support spring, releasing the locking rod from engagement with the limit ring and thus releasing the restriction on the sleeve rod. When the operator rotates the knob to control the screw, the sleeve rod rotates, causing the fixed aluminum tube to rotate as well. This facilitates angle adjustment of the aluminum tube, avoiding the conventional method where adjusting the angle requires first releasing the fixing device, effectively improving overall processing efficiency.

[0017] 2. When the aluminum tube needs to be fixed, the aluminum tube is first placed on the surface of the sleeve rod. The operator manually rotates the knob, which drives the slide rod and connecting block to rotate. The connecting block then drives the lead screw to rotate together. The slider can only move to the right because it is restricted by the through groove through the support rod and push rod. Then, by pushing the push rod, the inner support plate is lifted and pressed against the inner wall of the aluminum tube, thus fixing the aluminum tube and preventing it from being fixed on the surface, which would affect the polishing.

Detailed Implementation

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: a surface polishing device for aluminum tube processing, including a workbench 1 and a polishing device 2 set on the top of the workbench 1. The top of the workbench 1 is provided with a fixing device 3 for fixing the aluminum tube. The fixing device 3 is composed of a sleeve rod 31, a clamp 32 and a fixing seat 33. The fixing device 3 is provided with a limit adjustment device 4. The limit adjustment device 4 includes: a limit toothed ring 41, a clamping rod 42, a top rod 43, a connecting rod 44, a support spring 45 and a cavity 46.

[0025] The bottom of the fixed seat 33 is fixed to the top of the workbench 1, the sleeve rod 31 passes through the fixed seat 33 and is rotatably connected to the fixed seat 33, and the clamp 32 is set on the sleeve rod 31.

[0026] The clamp 32 includes a connecting block 321, which is rotatably mounted on the inner wall of the sleeve 31. A lead screw 322 is fixed to the right side of the connecting block 321, and a slide rod 323 is provided on the left side of the connecting block 321. The slide rod 323 passes through the connecting block 321 and is slidably connected to it. A knob 324 is fixed to the left side of the slide rod 323. A return spring 325 is fixed to the left side of the connecting block 321. The end of the return spring 325 away from the connecting block 321 is fixed to a fixing plate 326. The slide rod 323 passes through the fixing plate 326 and is fixed to it. The lead screw 322 passes through the slider 327 and is threadedly connected to it. A push rod 328 is hinged to the outer surface of the slider 327. A through groove 329 is provided on the sleeve 31, and the push rod 328 passes through the through groove 329. The end of rod 328 away from slider 327 is hinged to inner support plate 3210. A support rod 3211 is hinged to the side of inner support plate 3210 near push rod 328. The end of support rod 3211 away from inner support plate 3210 is hinged to the inside of through groove 329. When it is necessary to fix the aluminum tube, the aluminum tube is first placed on the surface of sleeve rod 31. The operator manually rotates knob 324. Knob 324 drives slider 323 and connecting block 321 to rotate. Connecting block 321 can then drive lead screw 322 to rotate together. Because support rod 3211 and push rod 328 are restricted by through groove 329, slider 327 can only move to the right. Then, by pushing push rod 328, inner support plate 3210 is lifted and pressed against the inner wall of aluminum tube, thus fixing aluminum tube and preventing it from being fixed on the surface, which would affect grinding.

[0027] The limiting toothed ring 41 is fixed to the left side of the fixed base 33. A cavity 46 is provided inside the sleeve rod 31. The push rod 43 passes through the left side of the sleeve rod 31 and is slidably connected to it. The push rod 43 extends into the cavity 46. A support spring 45 is fixed to the inner wall of the cavity 46. The end of the support spring 45 away from the cavity 46 is fixed to the push rod 43. A connecting rod 44 is hinged to the right side of the push rod 43. The end of the connecting rod 44 away from the push rod 43 is hinged to a locking rod 42. The locking rod 42 passes through the sleeve rod 31 and is slidably connected to it. The locking rod 42 connects to the limiting toothed ring 41. The locking mechanism restricts the movement of the sleeve rod 31, ensuring that when the operator is controlling the rotation of the lead screw 322 to support the inner support plate 3210 and fix the aluminum tube, the slider 327 and sleeve rod 31 cannot rotate with the lead screw 322. When the operator pulls the knob 324 to move the slide rod 323 to the left, the slide rod 323 moves to the left along with the fixing plate 326. The fixing plate 326 no longer resists the top rod 43, and the top rod 43 can then move to the left under the action of the support spring 45. The top rod 43 pulls the locking rod 42 closer to the sleeve rod via the connecting rod 44. The center of 31 moves to one side, causing the locking rod 42 to no longer engage with the limiting toothed ring 41, thus releasing the restriction on the sleeve rod 31. At this time, when the operator turns the knob 324 to control the lead screw 322 to rotate, the friction between the lead screw 322 and the slider 327, and the abutment of the push rod 328, will drive the sleeve rod 31 to rotate together, thereby driving the fixed aluminum tube to rotate together, which facilitates the adjustment of the angle of the aluminum tube. After the adjustment is completed, simply release the knob 324, and the slide rod 323 and the fixing plate 326 will be released under the action of the return spring 325. Reset to the right, the fixing plate 326 pushes the top rod 43 to move to the right, and the top rod 43 pushes the locking rod 42 to move away from the sleeve rod 31 through the connecting rod 44. The locking rod 42 re-engages with the limiting toothed ring 41. Even if it cannot engage immediately, the locking rod 42 can be engaged with the limiting toothed ring 41 by slightly rotating the sleeve rod 31, thus restricting the sleeve rod 31 and ensuring that the aluminum tube will not rotate during grinding and polishing. This avoids the conventional situation where the aluminum tube can only be adjusted after the fixing of the aluminum tube is released, effectively improving the overall processing efficiency.

[0028] The polishing equipment 2 includes a drive motor 21, which is fixed on the left side of the worktable 1. The output shaft of the drive motor 21 passes through the worktable 1 and is fixed to a threaded rod 22. The threaded rod 22 passes through a movable frame 23 and is threadedly connected to the movable frame 23. The movable frame 23 is slidably mounted on the top of the worktable 1. A polishing motor 24 is fixed on the top of the movable frame 23. A polishing wheel 25 is fixed to the output shaft of the polishing motor 24. By controlling the rotation of the threaded rod 22 through the drive motor 21, the movable frame 23 can be moved left and right, thus enabling the polishing motor 24 to move left and right with the polishing wheel 25. The polishing motor 24 drives the polishing wheel 25 to rotate, thereby achieving better polishing of the aluminum tube.

[0029] In this invention, during use, the aluminum tube to be polished is placed on the surface of the sleeve rod 31. The operator manually rotates the knob 324. At this time, the fixing plate 326 is in contact with the top rod 43, and the locking rod 42 is engaged with the limiting toothed ring 41. As a result, the sleeve rod 31 cannot rotate. The knob 324 drives the sliding rod 323 and the connecting block 321 to rotate. The connecting block 321 then drives the lead screw 322 to rotate together. The support rod 3211 and the push rod 328 are restricted by the through groove 329, and the slider 327 can only move to the right. Then, by pushing the push rod 328, the inner support plate 3210 is lifted and pressed against the inner wall of the aluminum tube, thus fixing the aluminum tube and preventing it from being fixed on the surface, which would affect the polishing.

[0030] By controlling the rotation of the threaded rod 22 by the drive motor 21, the moving frame 23 can be controlled to move left and right, so that the polishing motor 24 can move the polishing wheel 25 left and right. The polishing motor 24 drives the polishing wheel 25 to rotate, so as to achieve better polishing of the aluminum tube.

[0031] When the aluminum tube needs to be rotated and adjusted, the operator pulls knob 324, causing slide bar 323 to move to the left. Slide bar 323, along with fixing plate 326, moves to the left, and fixing plate 326 no longer opposes push rod 43. Push rod 43 can then move to the left under the action of support spring 45. Push rod 43, through connecting rod 44, pulls locking rod 42 to the side closer to the center of sleeve rod 31, so that locking rod 42 is no longer engaged with limiting toothed ring 41, thus releasing the restriction on sleeve rod 31. At this time, when the operator rotates knob 324 to control lead screw 322 to rotate, the friction between lead screw 322 and slider 327, and the action of push rod 328, causes the tube to move to the left. The moving sleeve rod 31 rotates together, thereby driving the fixed aluminum tube to rotate as well, which facilitates the adjustment of the angle of the aluminum tube. After the adjustment is completed, simply release the knob 324, and the sliding rod 323 and the fixing plate 326 will return to the right under the action of the return spring 325. The fixing plate 326 pushes the top rod 43 to move to the right. The top rod 43 pushes the locking rod 42 to move away from the sleeve rod 31 through the connecting rod 44. The locking rod 42 re-engages with the limiting toothed ring 41. Even if it cannot engage immediately, simply rotate the sleeve rod 31 slightly to engage the locking rod 42 with the limiting toothed ring 41, thereby restricting the sleeve rod 31 and ensuring that the aluminum tube will not rotate during grinding and polishing.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
