Description

Technical Field

[0001] This invention belongs to the field of irregular trimming and polishing technology, and in particular relates to a trimming and polishing device for the production of irregular molded products and its usage method. Background Technology

[0002] Irregularly shaped molded products refer to molded products with non-standard shapes. Molten plastic is injected into the mold cavity under high pressure, and then demolded after cooling. It is suitable for mass production of high-precision, complex parts. In the intelligent production process of irregularly shaped molded products, because the molten material is injected or pressed into the mold cavity under high pressure, and the mold is composed of two or more parts, there are extremely fine gaps between their closed surfaces. Material will squeeze into these gaps, and after cooling, it will form excess film-like or sheet-like residues. Burrs may affect the assembly, sealing performance and smooth movement of parts, causing dimensional deviations and affecting the fit between parts. In intelligent processing, irregularly shaped molded products need to be trimmed and polished.

[0003] In common edge trimming and sanding operations, the sanding equipment is placed close to the circumference of the mold, and its movement along the circumference of the molded product is controlled to perform edge trimming and die-cutting operations. However, in actual use, the circumference of irregularly shaped molded products is uneven, and fixed sanding equipment is prone to creating sanding blind spots. Furthermore, during the circumference sanding process, the molded product or sanding equipment needs to be constantly adjusted, and the adjustment range is prone to deviation, easily leading to repeated sanding or repetitive sanding, affecting the sanding effect. To address these issues, we provide an edge trimming and sanding device for the production of irregularly shaped molded products and its usage method to solve the above-mentioned technical problems. Summary of the Invention

[0012] A hollow guide column is fixedly connected to the upper surface of the adjusting transmission block. An adjusting slide is provided on the periphery of the hollow guide column. The adjusting slide consists of a horizontal slide and a vertical slide. A lifting screw coaxial with the hollow guide column is rotatably connected to the upper surface of the adjusting transmission block.

An extension support plate is fixedly connected to the periphery of the transmission branch. The extension support plate is slidably engaged with the adjusting slide. An adjusting support plate is fixedly connected to the lower surface of the extension support plate.

[0013] The present invention is further configured such that the adjusting support assembly includes a rotatably configured transverse transmission frame and a rotatably configured longitudinal transmission frame, both of which are rotatably configured on the lower surface of the adjusting support plate via ear plates; the adjusting support assembly also includes an adjusting ball, the adjusting ball having a transverse slide rail and a longitudinal slide rail on its peripheral side, a transverse arc-shaped block slidably configured inside the transverse slide rail, the transverse arc-shaped block being fixedly connected to the adjusting support plate via a first column, a longitudinal arc-shaped block slidably configured inside the longitudinal slide rail, a second column being fixedly connected to the peripheral side of the longitudinal arc-shaped block, the second column being slidably engaged with the transverse transmission frame and the longitudinal transmission frame.

[0014] A grinding support table is fixedly connected to one end of the longitudinal transmission frame.

The lower end of the adjustment column is in close contact with the grinding control table. A grinding disc is fixedly connected to the lower surface of the grinding control table.

[0015] A method for trimming and sanding irregularly shaped molded products includes the following steps: S01. The irregularly shaped molded product is placed between the first limiting member and the second limiting member. The second limiting member moves horizontally, and the limiting column contacts the irregularly shaped molded product until the position of the irregularly shaped molded product is limited by the limiting column of the first limiting member and the second limiting member. S02. The lifting screw rotates, and the extension support plate slides along the inside of the adjustment slide, so that the grinding disc is opposite to the second limit piece. The adjustment transmission block slides along the inside of the guide slide, driving the adjustment support assembly to move synchronously until the grinding disc is directly opposite the end of the irregular molded product. S03. Adjust the rotation of the horizontal transmission frame and the vertical transmission frame to control the tilt of the initial position of the grinding disc. Extend the support plate down until the grinding disc is in contact with the peripheral side of the irregular molded product, and the grinding disc rotates to perform grinding. S04. The adjusting transmission block slides forward along the inside of the guide slide, and the grinding disc moves radially along the circumferential side of the irregular molded product to perform fixed-direction grinding. The adjusting transmission block slides backward along the inside of the guide slide, and drives the pawl to drive the transmission ratchet to rotate. Under the restriction of the first limit member and the second limit member, the irregular molded product is rotated at a certain angle. S05. After the grinding disc moves to the initial grinding position, the grinding disc moves forward again to grind the irregularly shaped molded product in another axial direction. This process is repeated until the grinding of the irregularly shaped molded product's peripheral surface is completed.

[0016] The present invention has the following beneficial effects: 1. The present invention sets up a limiting support mechanism to control the second limiting member to move horizontally and gradually approach the first limiting member. When the limiting column contacts the irregular molded product, as the second limiting member moves, the limiting column slides along the inside of the limiting support tube and is compressed until the second limiting member stops moving. The position of the irregular molded product is limited by the first limiting member and the second limiting member, thereby realizing the position limitation of the irregular molded product and maintaining the position stability during grinding.

[0017] 2. This invention, by setting up a grinding adjustment component and an adjustment support component, allows the adjustment transmission block to move forward, driving the grinding disc to move radially along the circumferential side of the irregularly shaped molded product. When the adjustment transmission block moves horizontally in the opposite direction, the transmission support frame rotates under the meshing action of the transmission rack and the transmission outer gear ring, driving the pawl to drive the transmission ratchet to rotate. Under the restriction of the first and second limiting components, the irregularly shaped molded product is rotated at a certain angle. This cycle is repeated to achieve the grinding operation on the circumferential side of the irregularly shaped molded product, maintain the uniformity of the grinding operation, and avoid repeatedly rotating and adjusting the position of the irregularly shaped molded product.

[0018] 3. This invention, by setting up an adjustable support assembly, allows the horizontal transmission frame to rotate through the second column, causing the longitudinal arc-shaped block to slide along the interior of the longitudinal slide. This causes the grinding support table to deflect in the front-to-back direction, and the grinding disc to deflect synchronously. The vertical transmission frame, by rotating through the second column, causes the horizontal arc-shaped block to slide along the interior of the horizontal slide, driving the grinding support table to deflect in the left-to-right direction, and the grinding disc to deflect synchronously. By adjusting the rotation of the horizontal and vertical transmission frames, the tilt state of the grinding disc can be controlled, enabling grinding operations on irregularly shaped molded products at different angles and positions, thus improving the applicability of the equipment.

Detailed Implementation

[0033] 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.

[0034] For a specific implementation example, please refer to Implementation Example 1. Figure 1-12 The present invention relates to a trimming and grinding device for the production of irregularly shaped molded products and its usage method, comprising a fixedly configured limiting support mechanism 1. Specifically, the limiting support mechanism 1 includes a fixedly configured first limiting member 2 and a slidably configured second limiting member 3, which are slidably engaged with each other. A grinding adjustment component 4 is fixedly connected to the upper surface of the limiting support mechanism 1, and an adjustment support component 5 is fixedly connected to the lower surface of the grinding adjustment component 4.

[0035] Furthermore, the limiting support mechanism 1 is used to limit the position of the irregularly shaped molded product, and at the same time rotate and adjust the irregularly shaped molded product to facilitate trimming and grinding at different positions. The grinding and adjusting component 4 is used to control the horizontal position and lifting height of the adjusting support component 5. At the same time, when moving, it can drive the irregularly shaped molded product to rotate and adjust the trimming and grinding position. Adjustable support component 5 is used for trimming and grinding irregularly shaped molded products, and facilitates angle adjustment.

[0036] The operation process of this embodiment is as follows: The irregularly shaped molded product is placed between the first limiting member 2 and the second limiting member 3. The second limiting member 3 is controlled to move horizontally until both the first limiting member 2 and the second limiting member 3 are in close contact with the molded product, thereby limiting the position of the molded product. The grinding adjustment component 4 drives the adjustment support component 5 to move. The adjustment support component 5 moves horizontally to directly above the molded product and then moves downward until the adjustment support component 5 is in contact with the surface of the molded product. The grinding adjustment component 4 drives the adjustment support component 5 to move horizontally in the forward direction to grind the molded product. When the adjustment support component 5 moves horizontally in the reverse direction, the first limiting member 2 and the second limiting member 3 drive the molded product to rotate at a certain angle. The adjustment support component 5 then moves horizontally in the forward direction again to grind. This cycle is repeated to achieve the trimming and grinding of the molded product.

[0037] For a specific embodiment two, please refer to Figure 1-12 Based on the specific embodiment 1, specifically, the limiting support mechanism 1 also includes a limiting support component 6. The limiting support component 6 includes a fixedly installed limiting support platform 601. A limiting adjustment slide 602 is opened on the upper surface of the limiting support platform 601. An adjusting screw 603 is rotatably installed inside the limiting adjustment slide 602. A limiting motor is fixedly installed on one side of the limiting support platform 601. The output shaft of the limiting motor is fixedly connected to the adjusting screw 603.

[0038] Furthermore, both the first limiting member 2 and the second limiting member 3 include a limiting plate. A hollow limiting frame 201 is connected to one side of the limiting plate via a pivot. Several limiting springs 202 and limiting support tubes 203 are fixedly connected to the inner wall of the hollow limiting frame 201. The limiting springs 202 are coaxially arranged inside the corresponding limiting support tubes 203. A limiting horizontal column 204 corresponding to the limiting support tubes 203 is slidably arranged through the surface of the hollow limiting frame 201. The limiting horizontal column 204 and the corresponding limiting support tube 203 are slidably engaged, and the limiting horizontal column 204 and the corresponding limiting spring 202 are fixedly connected.

[0039] Furthermore, the limiting plate of the first limiting member 2 is fixedly connected to the upper surface of the limiting support platform 601, and a guide plate 205 is fixedly connected to one side of the limiting plate of the first limiting member 2 near the hollow limiting frame 201. A transmission bevel gear 206 is rotatably arranged on the other side of the limiting plate of the first limiting member 2, and the transmission bevel gear 206 is fixedly connected to the corresponding rotating shaft. The first limiting member 2 also includes a supporting shaft rotatably arranged on the upper surface of the limiting support platform 601 and a rotatably arranged transmission support frame 207, which is connected via... The support riser is fixedly connected to the upper surface of the limiting support platform 601. The support shaft is coaxial with the support riser. The support shaft slides through the transmission support frame 207. Several drive pawls 208 are rotatably connected to the bottom of the transmission support frame 207. A transmission external gear ring 209 is fixedly connected to the circumferential side of the transmission support frame 207. A transmission ratchet 210 is fixedly connected to the circumferential side of the support shaft. The drive pawls 208 and the transmission ratchet 210 are compatible. A drive bevel gear 211 that meshes with the transmission bevel gear 206 is fixedly connected to one end of the support shaft.

[0040] Furthermore, the limiting plate of the second limiting member 3 is slidably engaged with the limiting adjustment slide 602, and the limiting plate of the second limiting member 3 is threadedly engaged with the adjusting screw 603. A hollow transmission frame 301 is fixedly connected to one side of the limiting plate of the second limiting member 3. The hollow transmission frame 301 is slidably engaged with the guide plate 205, and the hollow transmission frame 301 is opposite to the limiting adjustment slide 602. The hollow transmission frame 301 seals the limiting adjustment slide 602 to prevent debris generated during the grinding process from entering the interior of the limiting adjustment slide 602.

[0041] The operation process of this embodiment is as follows: The irregularly shaped molded product is placed between the first limiting member 2 and the second limiting member 3. The limiting motor is started to drive the adjusting screw 603 to rotate. Under the action of the threaded engagement between the adjusting screw 603 and the limiting plate of the second limiting member 3, the limiting plate of the second limiting member 3 slides inside the limiting adjustment slide 602. As the second limiting member 3 and the irregularly shaped molded product move, the irregularly shaped molded product comes into contact with the limiting crossbar 204. The second limiting member 3 and the irregularly shaped molded product continue to move, squeezing the limiting crossbar 204. The limiting spring 202 is compressed and the limiting crossbar 204 slides inside the corresponding limiting support tube 203 until the second limiting member 3 stops moving. Under the limiting action of the first limiting member 2 and the limiting crossbar 204 of the second limiting member 3, the position of the irregularly shaped molded product is limited.

[0042] For a specific embodiment three, please refer to Figure 1-12Based on specific embodiments one and two, specifically, the grinding adjustment component 4 includes a guide slide 401 fixedly connected to the upper surface of the limiting support platform 601. A transmission screw 402 is rotatably connected inside the guide slide 401. A transmission motor is fixedly installed on one side of the guide slide 401. The output shaft of the transmission motor is fixedly connected to the transmission screw 402. An adjustment transmission block 403 is slidably disposed inside the guide slide 401. The adjustment transmission block 403 is threadedly engaged with the transmission screw 402. A transmission rack 404 is fixedly connected to one side of the adjustment transmission block 403 through a transmission bracket. The transmission rack 404 meshes with the transmission outer gear ring 209.

[0043] Furthermore, a hollow guide column 405 is fixedly connected to the upper surface of the adjusting transmission block 403. An adjusting slide 406 is provided on the circumferential side of the hollow guide column 405. The adjusting slide 406 consists of a horizontal slide and a vertical slide connected together. A lifting screw 407, coaxial with the hollow guide column 405, is rotatably connected to the upper surface of the adjusting transmission block 403. A lifting motor is fixedly installed on the upper surface of the hollow guide column 405. The output shaft of the lifting motor is fixedly connected to the lifting screw 407. An internally sliding transmission branch pipe 408 is provided, and the transmission branch pipe 408 is threadedly engaged with the lifting screw 407. An extension support plate 409 is fixedly connected to the peripheral side of the transmission branch pipe 408, and the extension support plate 409 is slidably engaged with the regulating slide 406. The extension support plate 409 moves along an L-shaped trajectory under the constraint of the regulating slide 406. In the initial state, the extension support plate 409 is located inside the horizontal slide of the regulating slide 406. An adjusting support plate 410 is fixedly connected to the lower surface of the extension support plate 409.

[0044] Furthermore, the adjusting support assembly 5 includes a rotatably configured transverse transmission frame 501 and a rotatably configured longitudinal transmission frame 502. The transverse transmission frame 501 and the longitudinal transmission frame 502 are interleaved. Both the transverse transmission frame 501 and the longitudinal transmission frame 502 are rotatably mounted on the lower surface of the adjusting support plate 410 via ear plates. An adjusting motor is mounted on one side of the ear plate. The output shaft of the adjusting motor is fixedly connected to the corresponding transverse transmission frame 501 and the longitudinal transmission frame 502. The adjusting motor controls the rotation of the transverse transmission frame 501 and the longitudinal transmission frame 502. The adjusting support assembly 5 also includes a regulating ball 503. The body 503 has a transverse slide 504 and a longitudinal slide 505 on its circumferential side. A transverse arc block 506 is slidably disposed inside the transverse slide 504. The transverse arc block 506 is fixedly connected to the adjusting support plate 410 through a first column. A longitudinal arc block 507 is slidably disposed inside the longitudinal slide 505. A second column is fixedly connected to the circumferential side of the longitudinal arc block 507. The second column is slidably engaged with the transverse transmission frame 501 and the longitudinal transmission frame 502. When the transverse transmission frame 501 rotates, the angle in the longitudinal direction is adjusted. When the longitudinal transmission frame 502 rotates, the angle in the transverse direction is adjusted.

[0045] Furthermore, a grinding support table 508 is fixedly connected to one end of the longitudinal transmission frame 502. A transmission gear 509 and a drive gear 510 are rotatably connected to the lower surface of the grinding support table 508. A drive motor is fixedly mounted on the upper surface of the grinding support table 508. The output shaft of the drive motor is fixedly connected to the drive gear 510. The drive gear 510 meshes with the transmission gear 509. A transmission seat is fixedly connected to the lower surface of the transmission gear 509. A spherical linkage joint 511 is rotatably arranged inside the transmission seat. The circumferential side of the spherical linkage joint 511 is connected to the support column. There is a grinding control table 512; several hollow columns 513 are fixedly connected to the lower surface of the grinding support table 508, and control columns 514 are slidably arranged on the hollow columns 513. Longitudinal springs 515 are fixedly connected between the control columns 514 and the corresponding hollow columns 513, and the lower end of the control columns 514 is in close contact with the grinding control table 512. In the initial state, the longitudinal springs 515 are all in a compressed state. A grinding disc 516 is fixedly connected to the lower surface of the grinding control table 512. In the initial state, the grinding disc 516 is deviated from the first limiting member 2 and the second limiting member 3.

[0046] The operation process of this embodiment is as follows: After the position of the irregularly shaped molded product is restricted, the lifting motor is started to drive the lifting screw 407 to rotate. Under the rotation of the lifting screw 407, the transmission branch pipe 408 rotates synchronously, and the extension support plate 409 slides inside the horizontal slide of the adjustment slide 406. Then, under the connection of the extension support plate 409, the grinding disc 516 is driven to rotate synchronously horizontally until the extension support plate 409 moves to the end of the horizontal slide and is opposite to the vertical slide. The grinding disc 516 is opposite to the second limiting member 3. The transmission motor is started to drive the transmission screw 402 to rotate. Under the threaded cooperation of the transmission screw 402 and the adjusting transmission block 403, the adjusting transmission block 403 slides inside the guide slide 401, thereby driving the adjusting support assembly 5 to move synchronously until the grinding disc 516 is directly opposite the end of the irregularly shaped molded product.

[0047] Before polishing, the horizontal transmission frame 501 is rotated, and the second column moves synchronously with the horizontal transmission frame 501. The second column slides inside the vertical transmission frame 502, and the vertical arc block 507 slides inside the vertical slide rail 505, causing the polishing support table 508 to deflect in the front-back direction. The polishing disc 516 deflects synchronously. The vertical transmission frame 502 is rotated, and the second column moves synchronously with the vertical transmission frame 502. The second column slides inside the horizontal transmission frame 501. Since the position of the horizontal arc block 506 is fixed, the control ball 503 rotates, and the horizontal arc block 506 slides inside the horizontal slide rail 504, causing the polishing support table 508 to deflect in the left-right direction. The polishing disc 516 deflects synchronously. By adjusting the rotation of the horizontal transmission frame 501 and the vertical transmission frame 502, the tilt state of the polishing disc 516 is controlled, which facilitates the polishing operation of irregularly shaped molded products at different angles.

[0048] Then, the lifting motor drives the lifting screw 407 to rotate. Due to the restriction of the inner wall of the regulating slide 406 on the extension support plate 409, and the threaded engagement between the lifting screw 407 and the transmission support pipe 408, the extension support plate 409 slides downward along the vertical slide of the regulating slide 406, thereby driving the adjusting support assembly 5 to move downward synchronously until the grinding disc 516 is in contact with the peripheral side of the irregularly shaped molded product. When the grinding disc 516 is in contact with the irregularly shaped molded product, due to the peripheral side of the irregularly shaped molded product... Since the surface is not smooth, after the grinding disc 516 comes into contact with the irregularly shaped molded product, it is obstructed by the irregularly shaped molded product. As the grinding disc 516 continues to move downward, the grinding disc 516 is subjected to the reaction force of the irregularly shaped molded product. The corresponding side adjustment column 514 slides along the inside of the hollow column 513, the longitudinal spring 515 is compressed, and the ball joint 511 rotates, so that the grinding control table 512 and the grinding disc 516 are both in an inclined state until the grinding disc 516 is in close contact with the peripheral side of the irregularly shaped molded product to increase the contact area.

[0049] The drive motor is started, which drives the drive gear 510 to rotate. Under the meshing action of the drive gear 510 and the transmission gear 509, the transmission gear 509 rotates, which in turn drives the transmission seat to rotate synchronously. Under the connection action of the ball joint 511 and the grinding control table 512, the grinding disc 516 rotates to grind the irregularly shaped molded product. The drive motor is started, which drives the transmission screw 402 to rotate. Under the threaded action of the transmission screw 402 and the adjusting transmission block 403, the adjusting transmission block 403 slides forward along the inside of the guide slide 401. Under the connection action of the adjusting support component 5, the grinding disc 516 moves radially along the circumferential side of the irregularly shaped molded product. During the movement, the grinding disc 516 continues to rotate, and as the circumferential side of the irregularly shaped molded product undulates, under the elastic recovery and compression action of the longitudinal spring 515, the grinding disc 516 tilts accordingly, maintaining the contact state between the grinding disc 516 and the irregularly shaped molded product, thus completing the grinding operation of the irregularly shaped molded product in one direction.

[0050] When the transmission screw 402 rotates in the reverse direction, the adjusting transmission block 403 slides in the reverse direction along the inside of the guide slide 401, and the adjusting support assembly 5 moves horizontally in the reverse direction. During this process, under the connection of the transmission bracket, the transmission rack 404 moves synchronously in the reverse direction. Under the meshing action of the transmission rack 404 and the transmission external gear ring 209, the transmission support frame 207 rotates, and the driving pawl 208 moves synchronously with the transmission support frame 207. Under the cooperation of the driving pawl 208 and the transmission ratchet 210, the transmission ratchet 210 rotates, thereby driving the driving bevel gear 211. The drive bevel gear 211 and the transmission bevel gear 206 mesh, causing the transmission bevel gear 206 to rotate. This, in turn, causes the hollow limiting frame 201 of the first limiting member 2 to rotate by a certain angle. Under the limiting action of the first limiting member 2 and the second limiting member 3, the irregularly shaped molded product rotates by a certain angle. When the grinding disc 516 moves to the initial grinding position, the grinding disc 516 moves forward again to grind the irregularly shaped molded product in another axial direction. This cycle continues until the grinding of the peripheral side of the irregularly shaped molded product is completed.
