Description

Technical Field

[0001] The utility model relates to a three-dimensional flexible combined assembly tool for a vibrating wheel, belonging to the technical field of construction machinery processing. Background Technique

[0002] The roller is a key core component of a road roller product. The production quality and production efficiency of the roller determine the development prospect of an enterprise. Therefore, excellent process equipment is the key to ensuring the welding quality of the roller.

[0003] The existing welding assembly tool for the roller drum of a road roller has no equal-height positioning tool. Workers on-site use scribing on the inner side of the steel ring and welding positioning rib plates. After the drum is hoisted in place, the drum is fixed by spot welding, and then the positioning rib plates are knocked off. Through finite element analysis and verification by on-site workers' experience, after the drum is welded, the welding deformation at the position where the sealing plate contacts the support cylinder is small, while the welding deformation at the outer edge of the sealing plate is relatively serious. The welding dimensions of the roller are completely out of control, resulting in a large machining allowance on one side of boring and facing, and no machining allowance on the other side. Machining is likely to cause the roller to be scrapped and cannot be repaired and reused. With the introduction of new products, the number of roller positioning tools gradually increases, causing on-site chaos and high manufacturing costs.

[0004] At the same time, for the welding of the roller drum of each model, a matching welding assembly tool is made, resulting in multiple different tools stored on the assembly site, chaotic on-site placement, high manufacturing costs, unfavorable on-site management, and further affecting production efficiency. Therefore, there is an urgent need for a welding assembly tool for rollers that can be applied to multiple specifications and models to solve the above problems. Summary of the Invention

[0005] Object of the Invention: Aiming at the deficiencies in the prior art, the utility model provides a three-dimensional flexible combined assembly tool for a vibrating wheel. Through the cooperation of a positioning base and an adjustment support, adjustable support rods and positioning rods are arranged on the adjustment support to realize the height positioning of the drum, provide a stable welding and assembly environment, improve the assembly efficiency and welding quality, and ensure the qualified rate of products.

[0006] Technical Solution: A three-dimensional flexible combined assembly tool for a vibrating wheel includes a positioning base. The positioning base includes an upper mounting plate and a lower bottom plate with the same diameter. The upper mounting plate and the lower bottom plate are fixedly connected by a partition plate.

[0007] It further includes an adjustment support mounted on the upper mounting plate and adjustable horizontally. The adjustment supports are distributed at least three along the same circumferential direction with the center of the positioning base as the center of the circle.

[0008] Any of the adjustment supports includes a sliding seat slidably connected to the upper mounting plate, the sliding seat includes an upper support plate and a lower support plate, the upper support plate and the lower support plate are fixedly connected by side plates arranged on both sides, and there is a support rod near the outer side of the upper support plate and a positioning rod near the inner side, the height of the support rod is less than the height of the positioning rod, and the support rod can be longitudinally adjusted on the upper support plate.

[0009] The utility model provides a positioning base and an adjustable adjustment support. The adjustment support is adjusted horizontally on the upper mounting plate of the positioning base to adapt to the inner diameter size of the roller currently being welded and assembled. The support rod is supported on the bottom of the sealing plate of the roller, and the positioning rod is attached to the inner wall of the roller. The roller to be processed is highly positioned and laterally limited, so that the roller can be stably placed on the assembly tooling, and then the steel ring is put on for welding, which can achieve accurate and stable splicing. Compared with the traditional method of marking and welding the positioning plate for roller positioning, the utility model has high accuracy and convenient operation. At the same time, it can be applicable to the splicing of rollers and steel rings of multiple models, which greatly reduces production costs and improves production quality. In addition, the management of a single device is more convenient and occupies less space in the production area.

[0010] The support rod is configured as a T-shaped rod, the support rod passes through the upper support plate and cooperates with the light hole of the upper support plate, and an adjustment gasket is provided between the upper end of the support rod and the upper support plate.

[0011] The height adjustment of the support rod is determined by adjusting the number and thickness of the adjustment gaskets. The gaskets are low in cost and come in many specifications. In the process of adjusting the height, it is only necessary to subtract the initial height of the tooling from the height of the current welding point between the roller to be processed and the edge of the steel ring to obtain the height that needs to be adjusted, and then precise positioning can be achieved by adding the adjustment gaskets. The light hole coordination makes installation more convenient, and adding adjustment gaskets is faster. There is no extrusion deformation between the adjustment gaskets, and the positioning accuracy is higher.

[0012] The positioning rod comprises a mounting portion and a limiting portion, the outer diameter of the mounting portion is smaller than the outer diameter of the limiting portion, and the mounting portion penetrates the upper support plate and cooperates with the light hole of the upper support plate.

[0013] The mounting portion of the positioning rod cooperates with the light hole of the upper support plate, and the installation is convenient. It fits with the inner wall of the drum to limit the drum laterally, so as to prevent the drum from falling to one side.

[0014] The adjustment supports are distributed at equal angles along the same circumferential direction with the center of the positioning base as the center of the circle.

[0015] The evenly arranged adjustment supports can make the roller evenly stressed and stably supported after positioning is completed, ensuring the smooth progress of the splicing process, further improving the splicing efficiency, improving product quality, and making the overall tooling more beautiful.

[0016] The upper mounting plate is provided with at least three chutes corresponding to the positions of the sliding seats. The straight lines where the chutes are located intersect at the central position of the upper mounting plate. The sliding seats are positioned by a locking device passing through the lower support plate and the chutes.

[0017] Through the cooperation of the locking device and the chutes, the sliding seats can slide and adjust the horizontal position within the range of the chutes. The adjustment method is simple and convenient. When positioning the drum, the positioning rod is fitted to the inner wall of the drum, and then the locking can be achieved by the locking device to realize the support and positioning of the drum.

[0018] The locking device is set as a pneumatic locking pin. The pneumatic locking pin passes through the chutes and the lower support plate. An adjustable ball is arranged at the tail end of the pneumatic locking pin. When locking and limiting, the ball extends out and abuts against the upper side of the lower support plate.

[0019] By using the pneumatic locking pin for locking and limiting, the sliding seats can be locked quickly. Compared with the traditional bolt positioning method, it is faster and more stable, improving the positioning efficiency.

[0020] It further includes a large bottom plate arranged below the lower bottom plate. The diameter of the large bottom plate is larger than that of the lower bottom plate.

[0021] Setting the large bottom plate can increase the stability of the tooling. When placed on the workshop floor for work, the larger contact area can provide a more stable tooling during the welding work of the steel ring and the drum with higher weight. At the same time, as a supporting component for the large steel ring with a larger inner diameter, the large bottom plate provides a flat supporting surface during the splicing work, further improving the welding quality of the large steel ring and the drum and increasing the product yield rate.

[0022] The upper support plate and the lower support plate are respectively provided with two through holes corresponding to the upper and lower positions. The two through holes of the upper support plate are respectively installed with a support rod and a positioning rod, and the two positioning holes of the lower support plate are respectively installed with pneumatic locking pins.

[0023] The sliding seats are set to have the same structure in the up and down directions. During the installation process, there is no need to deliberately distinguish the up and down structures. Any side can provide the corresponding installation basis, simplifying the production process, reducing the production cost, shortening the installation time, improving the installation efficiency of the tooling, and further enhancing the production efficiency.

[0024] Radius equal division scales are arranged on both sides of the chutes.

[0025] It is convenient to quickly adjust and position the support, realizing quick die change.

[0026] Beneficial effects: By providing a positioning base and an adjustable adjustment support, the adjustment support is horizontally adjusted on the upper mounting plate of the positioning base to adapt to the inner diameter size of the drum to be welded and assembled. The support rod supports the bottom of the sealing plate of the drum, and the positioning rod fits against the inner wall of the drum, performing height positioning and lateral limiting on the drum to be processed, enabling the drum to be stably placed on the assembling tooling. Then, a steel ring is put on for welding work, which can achieve accurate and stable splicing. Compared with the traditional method of using a scribed welding positioning plate for drum positioning, it has high accuracy, convenient operation, and can be applied to the splicing work of drums and steel rings of multiple models, greatly reducing production costs, improving production quality, and making single equipment management more convenient, occupying less space in the production area.

[0041] The utility model sets a positioning base 1 and an adjustable adjustment support 2. The adjustment support 2 is adjusted horizontally on the upper mounting plate 11 of the positioning base 1 to adapt to the inner diameter of the roller currently being welded and assembled. The support rod 22 is supported on the bottom of the sealing plate of the roller, and the positioning rod 23 is attached to the inner wall of the roller. The roller to be processed is highly positioned and laterally limited, so that the roller can be stably placed on the assembly tooling, and then the steel ring is put on for welding, which can achieve accurate and stable splicing. Compared with the traditional method of marking and welding the positioning plate for roller positioning, the utility model has high accuracy and convenient operation.

[0043] The height adjustment of the support rod 22 is determined by adjusting the number and thickness of the adjustment gaskets 24. The gaskets are low in cost and have many specifications. In the process of adjusting the height, it is only necessary to subtract the initial height of the tooling from the height of the current welding point between the roller to be processed and the edge of the steel ring to obtain the height that needs to be adjusted, and then accurate positioning can be achieved by adding the adjustment gaskets 24; the light hole coordination makes installation more convenient, and adding adjustment gaskets 24 is faster, and there is no extrusion deformation between the adjustment gaskets 24, and the positioning accuracy is higher.

The outer diameter of the mounting portion 231 is smaller than the outer diameter of the limiting portion 232 . The mounting portion 231 passes through the upper support plate 211 and cooperates with the light hole of the upper support plate 211 .

[0045] The mounting portion 231 of the positioning rod 23 cooperates with the light hole of the upper support plate 211, and is easy to install. It fits with the inner wall of the drum to limit the drum laterally, thereby preventing the drum from falling to one side.

[0046] The adjustment supports 2 are distributed at equal angles along the same circumferential direction with the center of the positioning base 1 as the center of the circle.

[0047] The evenly arranged adjustment supports 2 can make the roller evenly stressed and stably supported after positioning is completed, thereby ensuring the smooth progress of the splicing process, further improving the splicing efficiency, improving product quality, and making the overall tooling more beautiful.

[0048] The upper mounting plate 11 is provided with at least three chutes 14 corresponding to the positions of the sliding seats 21.
