Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to an automated grinding device suitable for steel wheel weld rings. Background Technology

[0002] During the manufacturing process of steel wheels, the rim and spokes are usually connected by welding. After welding, a ring-shaped weld will be formed at the joint. In order to ensure the appearance quality, coating performance and structural strength of the product, the weld must be ground to remove welding slag and spatter, and to make the weld reinforcement smoothly transition with the arc contour of the steel wheel base material.

[0003] Currently, the grinding operation of steel wheel welds in the industry is gradually transforming from traditional manual grinding to automated grinding. Common automation solutions use industrial robots or multi-axis mobile platforms, with grinding tools such as grinding wheels, belt abrasives or floating grinding heads driven by motors at the end, to grind the welds according to a preset trajectory. Because steel wheels have a specific arc-shaped profile, while conventional automated grinding tools have grinding contact surfaces, such as the contact wheel of the sanding belt, the circumferential surface or end face of the grinding wheel, which are mostly flat or fixed regular curved surfaces, they essentially form "line contact" or local "point contact" when in contact with the workpiece.

[0004] When dealing with curved workpieces, this contact method results in a limited contact area, with the grinding pressure concentrated on the local high points of the weld. This can easily lead to excessive material removal in that area, while the transition areas on both sides of the curved contour may be under-ground. This not only fails to achieve a smooth transition between the weld and the base material, but may also grind multiple small planes or dents on the curved surface, destroying the original streamlined contour of the workpiece.

[0005] In other words, existing technologies have the following technical problems: ordinary grinding equipment often results in poor grinding effects when grinding steel wheel welds due to mismatched arc shapes. Therefore, an automated grinding device suitable for steel wheel weld rings is proposed to address the above problems. Summary of the Invention

[0006] This application provides an automated grinding device for steel wheel weld seams to solve the problem that ordinary grinding equipment in the prior art is prone to poor grinding effect due to arc mismatch when grinding steel wheel weld seams.

[0007] According to one aspect of this application, an automated grinding apparatus suitable for weld seams of steel wheel weld rings is provided, comprising: The machining platform is equipped with a three-axis motion module, which includes an X-axis motion unit, a Y-axis motion unit, and a Z-axis motion unit.

[0009] Furthermore, several magnetic blocks are fixedly installed on the upper surface of the elastic metal plate, and guide rollers are rotatably connected to both ends of the elastic metal plate.

[0010] Furthermore, a conveying drive unit is also provided on the upper surface of the connector; The conveying drive unit of the adjustable arc-shaped grinding assembly includes a support sleeve, a moving rod, a support spring, and a rotating roller; The support sleeve is fixedly installed on the upper surface of the connecting seat.

A rotating roller is rotatably connected to the connecting bracket. The rotating roller is used to press against the inner surface of the grinding belt. A drive motor is also fixedly installed on the side wall of the connecting bracket.

[0011] Furthermore, the polishing belt includes a flexible metal layer and a polishing layer, with the polishing layer fixedly connected to one side of the flexible metal layer.

[0012] Furthermore, the auxiliary cleaning mechanism includes a collection bin, a magnetic roller, and an adsorption belt; The collection chamber is located on the side of the grinding belt; magnetic rollers and non-magnetic rollers are rotatably connected to both sides of the inner cavity of the collection chamber, and an adsorption belt is sleeved between the magnetic rollers and the non-magnetic rollers.

[0013] Furthermore, a cleaning chamber is also provided at the bottom of the collection chamber. A rotatable rotating roller is installed in the inner cavity of the cleaning chamber. A flexible scraper is fixedly connected to the arc-shaped wall of the rotating roller. One end of the flexible scraper is used to contact the surface of the adsorption belt.

[0014] Furthermore, a first linkage wheel is rotatably connected to the side wall of the collection chamber, and the first linkage wheel is coaxially connected to the magnetic suction roller; The first linkage wheel is connected to the second linkage wheel via a linkage belt.

[0016] Furthermore, the first linkage gear is coaxially connected to the non-magnetic roller, and the second linkage gear is coaxially connected to the rotating roller.

[0017] To address the technical problem in the prior art where ordinary planar or line-contact grinding tools are difficult to adapt to the arc-shaped contour of steel wheels, easily leading to uneven grinding, over-grinding, or damage to the workpiece surface, this application designs an automated grinding device. Through a three-axis movement module, an adjustable arc-shaped grinding component can follow the trajectory of the weld seam on the steel wheel surface for grinding.

This helps to improve the consistency and smoothness of weld seam grinding, reduce operational intensity and environmental pollution risks, and achieves the beneficial effects of improving grinding quality and operational efficiency. It is particularly suitable for the batch automated grinding operation of steel wheel weld rings. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] Please see Figure 1 and Figure 2 As shown, an automated grinding device suitable for steel wheel weld rings includes: Processing platform 1, a three-axis moving module is installed on processing platform 1, the three-axis moving module includes X-axis moving unit 2, Y-axis moving unit 3 and Z-axis moving unit 4, which is used to drive the adjustable arc grinding component 6 to be positioned and moved in space; A connecting arm 5 is fixedly connected to the Z-axis moving unit 4. An adjustable arc-shaped grinding component 6 is fixedly connected to one end of the connecting arm 5 for grinding the weld 901 of the steel wheel 9. The adjustable arc-shaped grinding assembly 6 includes a grinding belt 601 and an arc-shaped backing component. The grinding belt 601 is fitted onto the arc-shaped backing component and is used to perform grinding operations by circulating under drive.

[0023] An auxiliary cleaning mechanism 7 is also fixedly connected to the side of the adjustable arc-shaped grinding component 6 to collect and remove debris generated during the grinding process.

[0024] This application utilizes a three-axis movement module to enable the adjustable arc-shaped grinding component 6 to follow the trajectory of the weld seam 901 on the surface of the steel wheel 9 during grinding. Furthermore, the integrated technical solution formed by the adjustable arc-shaped grinding component 6 and the auxiliary cleaning mechanism 7 allows the grinding belt 601 to actively adapt to the arc-shaped contour of the steel wheel 9, achieving surface-contact contour grinding. Simultaneously, it adsorbs and cleans iron filings during the grinding process, enhancing the automation and cleanliness of the grinding operation. This contributes to improving the consistency and smoothness of weld seam grinding, reducing operational intensity and environmental pollution risks, and ultimately improving grinding quality and operational efficiency. It is particularly suitable for the batch automated grinding of weld seams on steel wheel weld rings.

[0025] In one specific embodiment of this application, see [reference]. Figure 2 and Figure 11 As shown, the X-axis moving unit 2 includes an X-axis moving base 201, a moving frame 202, and an X-axis screw 203.

[0026] The machining platform 1 has a sliding groove cavity inside. X-axis moving seats 201 are slidably connected to both sides of the sliding groove cavity of the machining platform 1. A moving frame 202 is fixedly connected between the two X-axis moving seats 201. An X-axis screw 203 is rotatably connected in the inner cavity of the slide groove of the processing platform 1. The X-axis screw 203 passes through the movable frame 202 and is threadedly engaged with the movable frame 202. An X-axis servo motor 204 is fixedly installed on one side of the processing platform 1. The output shaft end of the X-axis servo motor 204 is fixedly connected to one end of the X-axis screw 203 to drive the X-axis screw 203 to rotate.

[0027] With this technical solution, when the X-axis servo motor 204 is started, it can drive the X-axis screw 203 to rotate, and then drive the moving frame 202 and the X-axis moving seat 201 connected thereto to move horizontally along the inner cavity of the slide groove of the processing platform 1 through the threaded engagement, thereby realizing the feed motion of the adjustable arc grinding assembly 6 along the X-axis direction.

[0028] In a preferred embodiment of this application, see [reference] Figure 2 and Figure 11 As shown, the Y-axis moving unit 3 includes a support frame 301, a fixed guide rod 302, and a Y-axis moving seat 303; Two support frames 301 are provided. The support frames 301 are slidably connected to both sides of the upper surface of the processing platform 1. The two support frames 301 are fixedly connected to two X-axis moving seats 201 to form a linkage structure, so that the support frames 301 can move synchronously along the X-axis with the X-axis moving seats 201.

[0029] A fixed guide rod 302 is fixedly connected between the two support frames 301. A Y-axis movable seat 303 is slidably connected to the fixed guide rod 302 to provide guidance and support for the Y-axis movable seat 303.

[0030] A Y-axis screw 304 is rotatably connected between the two support frames 301. The Y-axis screw 304 passes through the Y-axis movable seat 303 and is threadedly engaged with the Y-axis movable seat 303.

[0031] A Y-axis servo motor 305 is fixedly installed on one side of the support frame 301, and the end of the output shaft of the Y-axis servo motor 305 is fixedly connected to one end of the Y-axis screw 304.

[0032] With this technical solution, when the Y-axis servo motor 305 is started, it can drive the Y-axis screw 304 to rotate, thereby driving the Y-axis moving seat 303 to move horizontally along the length direction of the fixed guide rod 302, thus realizing the feed motion of the connecting arm 5 and the adjustable arc-shaped grinding assembly 6 along the Y-axis direction.

[0033] In a preferred embodiment of this application, see [reference] Figure 12 As shown, the Z-axis moving unit 4 includes a Z-axis guide housing 401, a Z-axis moving seat 402, and a Z-axis screw 403. The Z-axis guide housing 401 is fixedly disposed on the side wall of the Y-axis moving seat 303. The Z-axis moving seat 402 is slidably connected in the inner cavity of the Z-axis guide housing 401. The connecting arm 5 is fixedly disposed on the side wall of the Z-axis moving seat 402 and is used to transmit the up and down movement of the Z-axis moving seat 402 to the connecting arm 5. A Z-axis screw 403 is rotatably connected between the upper and lower walls of the inner cavity of the Z-axis guide housing 401. The Z-axis screw 403 passes through the Z-axis moving seat 402 and is threadedly engaged with the Z-axis moving seat 402. A Z-axis servo motor 404 is fixedly connected to the upper end of the Z-axis guide housing 401. The end of the output shaft of the Z-axis servo motor 404 is fixedly connected to one end of the Z-axis screw 403.

[0034] With this technical solution, when the Z-axis servo motor 404 is started, it can drive the Z-axis screw 403 to rotate, thereby driving the Z-axis moving seat 402 to move up and down in the Z-axis guide housing 401, thus realizing the lifting and lowering movement of the connecting arm 5 and the adjustable arc-shaped grinding assembly 6 along the Z-axis direction to adjust the grinding pressure or avoid the workpiece.

[0035] In one specific embodiment of this application, see [reference]. Figure 3 As shown, the arc-shaped backing component of the adjustable arc-shaped grinding assembly 6 includes a connecting seat 602, an electric telescopic rod 603, an elastic metal plate 605, a connecting rod 608, and a support frame 610. The connecting seat 602 is fixedly installed at one end of the connecting arm 5. Both ends of the electric telescopic rod 603 are equipped with first hinges 604. One end of the electric telescopic rod 603 is rotatably connected to the connecting seat 602 through the first hinge 604, and the other end of the electric telescopic rod 603 is rotatably connected to the elastic metal plate 605 through the first hinge 604 to form the driving end.

[0036] There are two connecting rods 608, and each end of the two connecting rods 608 is equipped with a second hinge 609. The upper ends of the two connecting rods 608 are rotatably connected to the bottom surface of the connecting seat 602 through the second hinge 609, and the bottom ends of the connecting rods 608 are rotatably connected to the elastic metal plate 605 through the second hinge 609, forming a symmetrically arranged connecting rod mechanism.

[0037] Through this technical solution, when the electric telescopic rod 603 performs telescopic movement, it can push or pull the middle part of the elastic metal plate 605, thereby causing the elastic metal plate 605 to bend under the constraint and linkage of the connecting rod 608, thus realizing the function of adjusting the curvature of the working surface of the elastic metal plate 605.

[0038] Further, see Figure 3 and Figure 5As shown, several magnetic blocks 606 are fixedly installed on the upper surface of the elastic metal plate 605 to generate a magnetic field to attract the grinding belt 601. Guide rollers 607 are rotatably connected to both ends of the elastic metal plate 605 to support and guide the movement path of the grinding belt 601.

[0039] Furthermore, a support frame 610 is fixedly connected to each of the two connecting rods 608, and a magnetic suction plate 611 is fixedly connected to the support frame 610 to extend the coverage of the magnetic field and contact the corresponding area of ​​the grinding belt 601 to provide auxiliary adsorption force and support the grinding belt 601.

[0040] As a preferred technical solution, please refer to Figure 3 and Figure 5 As shown, a conveying drive unit is also provided on the upper surface of the connecting seat 602 to provide driving force to the grinding belt 601 sleeved on the guide roller 607 and the arc-shaped backing component.

[0041] See Figure 5 and Figure 6 As shown, the conveying drive unit of the adjustable arc-shaped grinding assembly 6 includes a support sleeve 612, a moving rod 613, a support spring 614, and a rotating roller 615.

[0042] The support sleeve 612 is fixedly installed on the upper surface of the connecting seat 602. A movable rod 613 is slidably connected in the inner cavity of the support sleeve 612. A connecting bracket 616 is fixedly connected to the upper end of the movable rod 613. A rotating roller 615 is rotatably connected to the connecting bracket 616. The rotating roller 615 is used to press against the inner surface of the grinding belt 601 to form a friction transmission.

[0043] A drive motor 617 is also fixedly installed on the side wall of the connecting bracket 616. The output shaft end of the drive motor 617 is fixedly connected to one end of the rotating roller 615, forming a power source for driving the grinding belt 601 to circulate.

[0044] With this technical solution, when the drive motor 617 starts, it can drive the rotating roller 615 to rotate, thereby driving the grinding belt 601 to rotate through friction. At the same time, one end of the support spring 614 is fixedly connected to the upper surface of the connecting seat 602, and the other end of the support spring 614 is fixedly connected to the bottom surface of the connecting bracket 616 to apply elastic force to the connecting bracket 616. Through the elastic force of the support spring 614, the rotating roller 615 can always be pressed against the grinding belt 601, thereby providing a stable driving force. At the same time, this floating design allows the rotating roller 615 to adapt to changes in the length of the grinding belt 601 within a certain range, making the transmission more reliable.

[0045] As a further technical solution, see [link / reference]. Figure 4As shown, in order to achieve contour grinding of the weld 901 of the steel wheel 9 and facilitate fixation, the grinding belt 601 includes a flexible metal layer 6011 and a grinding layer 6012. The grinding layer 6012 is fixedly connected to one side of the flexible metal layer 6011. The grinding layer 6012 is used to contact the weld 901 of the steel wheel 9 and perform grinding. By setting a flexible metal layer 6011, it can be attracted by the magnetic field generated by the magnetic block 606 and the magnetic plate 611, and then fixed to the surface of the arc-shaped backing component. With the arc-shaped backing component of the adjustable arc-shaped grinding component 6, the grinding belt 601 adsorbed on its surface can form a corresponding arc by adjusting the arc-shaped backing component, so that the working surface of its grinding layer 6012 can fit with the weld 901 of the steel wheel 9 and the arc-shaped contours on both sides. Thus, under the drive of the drive motor 617, the weld 901 is subjected to contour grinding, so that the ground weld area can smoothly transition with the arc surface of the base material.

[0046] To reduce frictional resistance when the grinding belt 601 moves, one side of the elastic metal plate 605 and the magnetic plate 611 is smoothed or covered with a low-friction material layer for contact and cooperation with the flexible metal layer 6011 of the grinding belt 601, thereby reducing the coefficient of friction during relative movement without affecting the magnetic attraction effect.

[0047] The adjustable arc-shaped grinding component 6 of this application can, on the one hand, change the curvature of the elastic metal plate 605 by adjusting the extension and retraction of the electric telescopic rod 603, so as to match the arc contour of the steel wheel 9 of different specifications, thereby achieving arc-adjustable contour grinding. On the other hand, it also has a magnetic fixing function. When grinding, the magnetic block 606 and the magnetic plate 611 can not only limit the grinding belt 601 and make it fit together to form an arc surface, but also simultaneously adsorb some of the ferromagnetic debris generated during grinding, reducing the debris from flying around.

[0048] In a preferred embodiment of this application, see [reference] Figure 3 and Figure 7 As shown, the auxiliary cleaning mechanism 7 includes a collection bin 702, a magnetic roller 703, and an adsorption belt 705; One end of the mounting bracket 701 is fixedly connected to one side of the collection chamber 702, and the other end of the mounting bracket 701 is fixedly connected to the side wall of the connecting arm 5 to form an integral connection. The collection chamber 702 is located at the side of the grinding belt 601.

[0049] A magnetic roller 703 and a non-magnetic roller 704 are rotatably connected to both sides of the inner cavity of the collection chamber 702, and an adsorption belt 705 is sleeved between the magnetic roller 703 and the non-magnetic roller 704. The magnetic roller 703 is located near the outer surface of the grinding belt 601. When rotating, it acts on the adsorption belt 705 through its magnetic field, causing the section of the adsorption belt 705 near the grinding belt 601 to generate magnetic force, adsorbing the ferromagnetic debris attached to the surface of the grinding belt 601 and causing it to detach from the surface of the grinding belt 601, thereby playing the role of automatically cleaning debris.

[0050] Further, see Figure 10 As shown, the adsorption belt 705 includes a steel belt 7051 and a flexible scraper 7052. Several flexible scrapers 7052 are fixedly arranged on the outer surface of the steel belt 7051 for contacting the outer surface of the grinding belt 601. Thus, when the adsorption belt 705 rotates and moves, on the one hand, the flexible scraper 7052 scrapes against the surface of the grinding belt 601, which can scrape and loosen the stubborn attached debris. At the same time, the magnetic field transmitted by the magnetic roller 703 in conjunction with the steel belt 7051 causes the loosened debris and nearby debris to be adsorbed onto the surface of the adsorption belt 705.

[0051] Furthermore, see Figure 9 As shown, a cleaning chamber 7021 is also provided at the bottom of the collection chamber 702. A rotatable rotating roller 709 is provided in the inner cavity of the cleaning chamber 7021. A flexible scraper 712 is fixedly connected to the arc-shaped wall of the rotating roller 709. One end of the flexible scraper 712 is used to contact the surface of the adsorption belt 705, thereby scraping off the debris adsorbed on its surface.

[0052] Through the above technical solution, when the adsorption belt 705 carries debris to the position of the non-magnetic roller 704, the magnetic field effect weakens or disappears due to the distance from the magnetic roller 703, and the adhesion of the debris decreases, making it easier to remove. At the same time, the flexible scraper 712 set in the cleaning chamber 7021 can scrape the surface of the adsorption belt 705 under the rotation action, further peeling off the debris, so that the debris falls into the bottom of the collection chamber 702 for centralized processing, which plays the role of automatically collecting debris and keeping the adsorption belt 705 clean.

[0053] As a preferred technical solution, please refer to Figure 8 As shown, in order to simplify the drive structure, a first linkage wheel 706 is rotatably connected to the side wall of the collection chamber 702. The first linkage wheel 706 and the magnetic suction roller 703 are coaxially connected to form a synchronous rotation relationship. The first linkage wheel 706 is connected to the second linkage wheel 707 via the linkage belt 708. The second linkage wheel 707 is located on one side of the rotating roller 615 and is coaxially connected to the rotating roller 615, forming a power transmission path from the rotating roller 615 to the first linkage wheel 706. With this technical solution, when the drive motor 617 drives the rotating roller 615 to rotate, the first linkage wheel 706 and the second linkage wheel 707 can be driven to rotate synchronously through the linkage belt 708, thereby driving the magnetic roller 703 to rotate, so that its linear speed matches that of the grinding belt 601, thus achieving synchronous cleaning.

[0054] The side wall of the collection chamber 702 is also rotatably connected to a first linkage gear 710 and a second linkage gear 711. The first linkage gear 710 and the second linkage gear 711 mesh with each other. The first linkage gear 710 is coaxially connected to the non-magnetic roller 704, and the second linkage gear 711 is coaxially connected to the rotating roller 709, forming a gear transmission relationship. Through this technical solution, the rotation of the non-magnetic roller 704 can drive the first linkage gear 710 to rotate, which in turn meshes and drives the second linkage gear 711 to rotate in the opposite direction to the rotating roller 709, thereby realizing the active scraping and cleaning of the adsorption belt 705 by the flexible scraper 712.

[0055] This application, through the combination of adjustable arc-shaped grinding component 6 and auxiliary cleaning mechanism 7, can achieve grinding and debris collection of weld seam 901 of steel wheel 9. On the one hand, the adjustable arc-shaped contour grinding method makes the grinding belt 601 fit more closely with the workpiece arc surface and the grinding pressure distribution more uniform, which helps to obtain a smooth grinding surface and reduces the possibility of over-grinding or under-grinding. On the other hand, the auxiliary cleaning mechanism 7 can simultaneously adsorb and collect most of the ferromagnetic debris during the grinding process, reducing the impact of debris splashing on the working environment and equipment, and also reducing the need for subsequent cleaning work. It is particularly suitable for continuous and clean grinding of weld seam of steel wheel weld ring on automated production lines.

[0056] In one specific embodiment of this application, see [reference]. Figure 1 As shown, it also includes a steel wheel support unit 8 for supporting and driving the steel wheel 9 to rotate.

[0057] There are four steel wheel support units 8, which are symmetrically arranged on the processing platform 1 and located below the adjustable arc-shaped grinding assembly 6.

[0058] Each steel wheel support unit 8 includes a support leg 801, a contact wheel 802, and a power motor 803.

[0059] The support bracket 801 is fixedly mounted on the upper surface of the processing platform 1. The contact wheel 802 is rotatably connected to the top of the support bracket 801 via a bearing, and its wheel surface is used to contact the outer edge of the steel wheel 9 to support the weight of the steel wheel 9.

[0060] The power motor 803 is fixedly mounted on the support bracket 801, and its output shaft is connected to the rotating shaft of the contact wheel 802 to drive the contact wheel 802 to rotate.

[0061] With this technical solution, when it is necessary to perform circumferential grinding on the weld 901 of the steel wheel 9, the steel wheel 9 can be placed on the contact wheels 802 of the four steel wheel support units 8. The power motor 803 is started, which drives the contact wheels 802 to rotate. Then, through friction, the steel wheel 9 is slowly rotated around its central axis. At the same time, the spatial position of the adjustable arc grinding component 6 is adjusted by the three-axis moving module so that it is aligned with the weld 901 area and appropriate pressure is applied. Under the combined action of the rotational motion of the steel wheel 9 and the grinding motion of the adjustable arc grinding component 6, continuous and automated grinding processing of the entire weld 901 of the steel wheel 9 can be achieved.
