Description

Technical Field

[0001] This invention relates to the field of cable reel processing equipment technology, and in particular to a small edge grinding and grooving machine for cable reels. Background Technology

[0002] A cable reel is a type of reel designed for winding cables. Its structure generally includes a central roller for winding the cable, and support discs at both ends of the roller to limit and support the cable on the roller. Existing support discs include a central annular metal wheel and an outer metal ring. A fan-shaped wooden board is laid between the metal ring and the metal wheel. During processing, grooves need to be cut into the curved surface of the outer end of the board, and also into the inner end. Furthermore, the curved and straight edges of the board need to be ground to facilitate later installation. In actual processing, when the sum of the length of the board and the radius of the inner metal wheel equals the radius of the metal ring, the three components are matched during installation.

[0003] In existing technologies, grooving machines are generally used for grooving wood boards, while sanders are used for sanding the edges. However, both of these machines are typically used for processing straight-lined boards. When grooving or sanding curved edges is required, manual control of the template rotation angle is necessary. During grooving or sanding, the wood board cannot be positioned correctly. Grooving positions are prone to shifting, and the depth of grooving or sanding depends entirely on the operator's experience. After processing, the diameter of the groove often deviates significantly from the diameter of the metal ring. Furthermore, mismatches can easily occur when installing the sanded wood board's outer curvature and the outer metal ring. Summary of the Invention

[0015] (III) Beneficial Effects

[0016] This invention provides a small edge grinding and grooving machine for cable reels. During processing, the support sleeve can be adjusted and fixed according to the size of the cable reel to be processed, so that the plate to be processed swings in a circle with the radius of the cable reel when rotating for grooving or grinding. As a result, after grooving or grinding, the arc-shaped groove and the arc-shaped edge after grinding are more matched with the metal ring.

[0017] During processing, this device does not require positioning the rotation center of the clamping assembly. The first and second arc-shaped plates limit the processing end of the workpiece, ensuring that the processed arc-shaped groove and surface maintain the set curvature, thus guaranteeing a proper fit with the metal ring. Furthermore, the sliding connection between the support base and the slide groove ensures normal processing of the workpiece while reducing the overall size of the equipment and saving floor space.

[0018] After adjusting the position of the support sleeve and the rotating shaft, this application can process the arc plate on the entire cable reel. The processing process ensures the fit between the processed arc groove, arc surface and metal ring, while also improving the processing speed. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example

[0030] This invention provides a small edge grinding and grooving machine for cable reels, see [link / reference]. Figures 1-7 The system includes a worktable 100, with a slide groove 110 on the upper side of the worktable 100. A support base 200 is slidably disposed within the slide groove 110, and a clamping assembly 300 is rotatably disposed on the support base 200 to clamp the fixed end of the workpiece to be processed. A grooving mechanism 400 and an edge grinding mechanism 500 are spaced apart on the worktable 100, located at opposite ends of the slide groove 110. When the clamping assembly 300 rotates to coincide with the length direction of the slide groove 110, it grooves and grinds the processing end of the workpiece to be processed. Limiting components 600 are provided on both sides of the grooving mechanism 400 and the edge grinding mechanism 500 to limit the processing end of the workpiece to be processed. During processing, the workpiece to be processed is fixed by the clamping assembly 300, and the grooving mechanism 400 and the edge grinding mechanism 500 grooving and grinding the workpiece to be processed. The fixed end of the plate to be processed is the end closest to the center of the cable reel, which is connected to the central metal wheel. The processing end is the end furthest from the center of the cable reel, which is connected to the outer metal ring.

[0031] Specifically, the slide groove 110 has a T-shaped cross-section, and the support base 200 has a T-shaped cross-section. One end of the support base 200 slides within the slide groove 110, and the other end is located on the upper side of the slide groove 110. The end located on the upper side of the slide groove 110 is connected to the clamping assembly 300. A rectangular mounting opening is provided at one end of the slide groove 110, through which the support base 200 is placed within the slide groove 110.

[0032] The clamping assembly 300 includes a rotating arm 310, one end of which is connected to a rotating shaft 320 at the upper end of the support base 200. The rotating arm 310 is located above the worktable 100, and a support sleeve 330 is slidably mounted on the rotating arm 310. The width of the support sleeve 330 is greater than the width of the slide groove 110, and the lower side of the support sleeve 330 abuts against the worktable 100. The support sleeve 330 can support the worktable 100, improving stability during the rotary grooving or edge grinding process. A first locking screw 340 is threaded onto the support sleeve 330, passing through the support sleeve 330 and abutting against the rotating arm 310 inside the support sleeve 330.

[0033] The position of the support sleeve 330 can be locked by the first locking screw 340, thereby adjusting the distance between the support sleeve 330 and the rotating shaft 320. During processing, a suitable metal wheel, metal ring, and curved wooden board located between them are selected according to the diameter of the cable reel; the curved wooden board is the plate to be processed. The distance between the support sleeve 330 and the rotating shaft 320 is adjusted to the radius of the metal wheel. After fixing the plate to be processed, when the plate to be processed is controlled to rotate around the rotating shaft 320 to create a groove, it can be ensured that the groove is centered on the rotating shaft 320. Therefore, after installation, it can be ensured that the groove matches the outer metal ring.

[0034] An L-shaped support plate 350 is fixedly installed on the support sleeve 330. The L-shaped support plate 350 is located at the end of the support sleeve 330 away from the rotation axis 320. The L-shaped support plate 350 includes a vertical arm 351 connected to the support sleeve 330 and a horizontal arm 352 of a parallel rotating arm 310. The L-shaped support plate 350 is located on the upper side of the rotating arm 310. A clamping member 360 is provided at intervals on the horizontal arm 352. The fixed end of the plate to be processed is located between the horizontal arm 352 and the rotating arm 310. The clamping member 360 clamps the plate to be processed.

[0035] Specifically, two sets of clamping members 360 are spaced apart on the horizontal arm 352. Threaded holes 3521 are spaced apart on the horizontal arm 352. Each clamping member 360 includes a clamping screw 361 that passes through the threaded hole 3521. A clamping plate 362 is provided at one end of the clamping screw 361 located below the horizontal arm 352, and a knob 363 is provided at the other end of the clamping screw 361 located above the horizontal arm 352.

[0036] The L-shaped support plate 350 and the upper clamping member 360 are used to clamp and fix the workpiece to be processed. When fixing, the fixed end of the workpiece to be processed abuts against the vertical arm 351. Then, the clamping member 360 clamps the workpiece to be clamped, so that the clamping member 360 and the lower rotating arm 310 fix the workpiece to be clamped.

[0037] The grooving mechanism 400 includes a first drive motor 410 fixed to the lower side of the worktable 100. The output shaft of the first drive motor 410 passes through the worktable 100, and a grooving tool 420 of a predetermined size is detachably mounted on one end of the first drive motor 410. The output shaft of the first drive motor 410 drives the grooving tool 420 to rotate, and the grooving tool 420 grooves the workpiece. A limit ring 430 is rotatably mounted on the upper side of the grooving tool 420. During the grooving process, when the workpiece is rotated past the grooving tool 420, the workpiece is grooved. During the grooving process, the grooving depth is controlled by the limit ring 430 and the size of the grooving tool 420. When different depths of grooving are required on the workpiece, different grooving tools 420 need to be replaced.

[0038] Specifically, the output shaft end of the first drive motor 410 has a guide frame 411 with a cross-section in the shape of a cross. One end of the grooving tool 420 has a positioning hole 421 with a cross-section in the shape of a cross, and the guide frame 411 is fitted into the positioning hole 421. The other end of the grooving tool 420 has an integrally formed support column 422, located at the axis of the output shaft of the first drive motor 410. A limiting ring 430 is rotatably connected to the outside of the support column 422. The support column 422 has a through locking hole 423 along its axial direction, which connects to the positioning hole 421. The diameter of the locking hole 423 is smaller than the diameter of the positioning hole 421. A locking screw 424 is provided in the locking hole 423, passing through the locking hole 423 and threadedly connected to the guide frame 411. When different depths and heights of grooves are required, different grooving tools 420 can be used. A retaining ring 431 is provided on the support column 422. The retaining ring 431 limits the limiting ring 430, so that the limiting ring 430 can rotate and will not detach from the support column 422.

[0039] The limiting component 600 includes a first arc plate 610, the center of which is located at the center of the end of the slide groove 110 away from the grooving mechanism 400; the first arc plate 610 includes a first arc segment 611 and a second arc segment 612, which are located on both sides of the grooving cutter 420 and are on the same arc surface as the surface of the limiting ring 430 near the slide groove 110. By using the first arc segment 611 and the second arc segment 612, the clamping assembly 300 controls the rotation of the workpiece. The first arc segment 611 and the second arc segment 612 limit the processing end of the workpiece. When the workpiece moves towards the grooving tool 420 via the first arc segment 611, the support seat 200 moves gradually along the slide groove 110 towards the side furthest from the grooving tool 420 until the workpiece contacts the grooving tool 420 for grooving. During this process, it ensures a smooth transition between the workpiece and the grooving tool, preventing the grooving depth from being too deep at the front end. After grooving, the end of the workpiece abuts against the second arc segment 612, ensuring a smooth transition when the workpiece separates from the grooving tool 420, and ensuring that the grooving depth at the end is consistent with the middle position.

[0040] The edge grinding mechanism 500 includes a second drive motor 510 fixed to the lower side of the worktable 100. The output shaft of the second drive motor 510 passes through the worktable 100, and a grinding cylinder 520 is detachably connected to one end of the worktable 100. The limiting assembly 600 also includes a second arc-shaped plate 620, the center of which is located at the center of the end of the slide groove 110 away from the edge grinding mechanism 500. The second arc-shaped plate 620 includes a third arc-shaped segment 621 and a fourth arc-shaped segment 622, which are located on both sides of the grinding cylinder 520. The ends of the third arc-shaped segments 621 and 622 that are close to each other are arc-shaped and hug the grinding cylinder 520. The side of the grinding cylinder 520 near the slide groove 110 protrudes from the second arc-shaped plate 620, and the height of the protrusion is the grinding depth of the plate to be processed.

[0041] When grinding the workpiece, the clamping assembly 300 controls the rotation of the workpiece, causing it to rotate to one end of the grinding mechanism 500, where it is ground by the grinding cylinder 520. Before contacting the grinding cylinder 520, the workpiece abuts against the third arc segment 621, then makes stable contact with the grinding cylinder 520. After grinding, it makes stable contact with the fourth arc segment 622, ensuring more uniform grinding of the workpiece. The clamping assembly 300 keeps the workpiece fixed in the same position throughout the process. During rotation, it grooves and grinds the workpiece, ensuring that the center of the groove is concentric with the center of the outer edge of the workpiece after grinding. This results in a better fit when installed with the outer metal ring.

[0042] A first support plate 700 is provided on the upper side of the worktable 100, on the side of the first arc-shaped plate 610 near the slide groove 110. The first support plate 700 is arc-shaped, and the height of the upper surface of the first arc-shaped plate 610 is flush with the height of the upper surface of the rotating arm 310. The first support plate 700 provides support to the processing end of the workpiece during grooving, making the workpiece more stable during the rotation process.

[0043] A vertical first limiting surface 613 is formed on the side of the first arc-shaped plate 610 away from the slide groove 110. An arc-shaped grooving portion 440 is formed on the side of the first arc-shaped plate 610 closest to the slide groove 110. The grooving tool 420 protrudes from the first limiting surface 613 on the side closest to it, forming a straight grooving portion 450. This configuration allows the device to groove both arc-shaped surfaces and straight edges simultaneously.

[0044] A vertical second limiting surface 623 is formed on the side of the second arc-shaped plate 620 away from the slide groove 110. An arc-shaped grinding part 530 is formed on the side of the grinding cylinder 520 opposite to the second arc-shaped plate 620 and closer to the slide groove 110. A flat grinding part 540 protrudes from the second limiting surface 623 on the side closer to the second limiting surface 623. The arc-shaped grinding part 530 can grind arc-shaped surfaces, and the flat grinding part 540 can grind horizontal surfaces.

[0045] This invention provides a small edge grinding and grooving machine for cable reels. When grooving the arc-shaped edge of the plate to be processed, a suitable grinding tool is first selected and installed according to the position to be grooved. The fixed end of the plate to be processed is clamped by the clamping assembly 300. At the same time, the distance between the rotating shaft 320 and the support sleeve 330 is adjusted to the radius of the inner metal wheel of the cable reel. The support sleeve 330 is fixed by the first locking screw 340, so that the support sleeve 330 and the rotating arm 310 are kept in a fixed position. The operator controls the rotating arm 310 and the plate to be processed to rotate. During the rotation, the processing end of the plate to be processed is kept in contact with the first arc-shaped plate 610. During the rotation, the plate to be processed passes through the grinding tool. After grooving, the edge of the plate to be processed abuts the limiting ring 430. At this time, the grooving of the arc-shaped edge is completed.

[0046] When grinding the edge of the workpiece, simply control the workpiece to rotate via the clamping assembly 300, so that it rotates to one side of the grinding mechanism 500 and continues to rotate, so that the end of the workpiece abuts against the second arc plate 620 until it passes through the grinding cylinder 520, at which point the arc edge of the workpiece is ground.

[0047] When it is necessary to grind or groove the straight edge, simply place the plate to be processed on the side of the straight groove section 450 or the side of the flat grinding section 540 for grooving or grinding.

[0048] This invention provides a small edge grinding and grooving machine for cable reels. During processing, the support sleeve 330 can be adjusted and fixed according to the size of the cable reel to be processed, so that the plate to be processed swings in a circle with the radius of the cable reel when rotating for grooving or grinding. As a result, after grooving or grinding, the arc-shaped groove and the arc-shaped edge after grinding are more matched with the metal ring.

[0049] During processing, this device does not require positioning the rotation center of the clamping assembly 300. The first arc-shaped plate 610 and the second arc-shaped plate 620 limit the processing end of the workpiece, ensuring that the processed arc-shaped groove and surface maintain the set curvature, thus guaranteeing a proper fit with the metal ring. Furthermore, the sliding connection between the support base 200 and the slide groove 110 ensures normal processing of the workpiece while reducing the overall size of the equipment and saving floor space.

[0050] After adjusting the position of the support sleeve 330 and the rotating shaft 320, this application can process the arc plate on the entire cable reel. The processing process ensures the fit between the processed arc groove, arc surface and metal ring, while also improving the processing speed.
