Description

Technical Field

[0001] This utility model relates to the field of grinding roller overlay welding technology, specifically a grinding roller overlay welding fixture. Background Technology

[0002] During use, the working surface of the grinding roller is subjected to severe wear, impact and corrosion for a long time, which can easily lead to failure. Welding can achieve the dual effect of repairing the failed surface and strengthening the performance of the new roller by depositing a wear-resistant and corrosion-resistant alloy layer on the surface.

[0003] During the surfacing process, the grinding roller needs to be clamped and installed using tooling. A common method is to use a three-jaw chuck to clamp one end of the grinding roller and then use an ejector pin to abut against the center hole at the other end of the grinding roller to install and fix the grinding roller and assist in the rotation of the grinding roller during the subsequent surfacing process. The grinding roller itself is relatively heavy, and when the ejector pin abuts against the center hole of the grinding roller, the contact area is limited. This results in a relative rotational deviation between the end of the grinding roller and the ejector pin during the subsequent rotation of the grinding roller, which affects the stability of the surfacing operation.

[0004] Therefore, there is an urgent need for a grinding roller welding fixture to solve the above problems. Utility Model Content

[0017] Please see Figure 1-4 The present invention provides a grinding roller welding fixture, including an operating table 101, a fixed table 102 and a slide table 103 on the operating table 101, a driving component 105 for driving the slide table 103 on the operating table 101, a three-jaw chuck 104 for clamping and fixing one end of the grinding roller on the fixed table 102, a rotating component for rotating the three-jaw chuck 104 on the fixed table 102, and a central hole opened at both ends of the grinding roller. It should be noted here that the three-jaw chuck 104, the drive component 105 and the rotating component are conventional technical components in the technical field of this application, and their working principle and operation method are known technology, so they will not be described in detail here. Also includes: The ejector pin assembly is set on the slide table 103 to assist in squeezing and clamping the other end of the grinding roller, and the grinding roller is clamped under the action of the ejector pin assembly and the three-jaw chuck 104. A support assembly, mounted on the ejector pin assembly, is used to provide abutment support to the ends of the grinding roller during the compression and clamping process; It should be noted here that during the clamping and installation of the grinding roller to be welded, the cooperation between the ejector pin assembly and the support assembly reduces the probability of relative rotational deviation between the ejector rod 202 and the end of the grinding roller when the grinding roller rotates, thus ensuring the stable welding operation of the grinding roller.

[0018] The ejector assembly includes a mounting roller 201 disposed on a slide table 103, and a push rod 202 fixed at the front end of the mounting roller 201 for pressing against the center hole at the end of the grinding roller; It should be noted here that: one end of the grinding roller is clamped and fixed using a three-jaw chuck 104. After clamping, the slide 103 is driven to move toward the other end of the grinding roller by the drive component 105. During the movement, one end of the push rod 202 on the mounting roller 201 abuts against the center hole at the end of the grinding roller. Through the abutting and squeezing action and the clamping action of the three-jaw chuck 104, the clamping and installation of the grinding roller is completed.

[0019] The slide table 103 has a mounting hole, and a bearing is installed inside the mounting hole. The mounting roller 201 is sleeved and installed inside the bearing. It should be noted here that the mounting holes and bearings facilitate the rotational connection of the mounting roller 201.

[0020] The support assembly includes a mounting sleeve 301. The front side of the mounting sleeve 301 is connected to a support ring 302 for supporting the end of the grinding roller via an elastic component. A connecting transmission component for auxiliary connection transmission is provided between the mounting sleeve 301 and the mounting roller 201. The mounting sleeve 301, the mounting roller 201 and the support ring 302 are concentrically arranged. It should be noted here that by using the support components, the probability of relative rotational deviation between the push rod 202 and the end of the grinding roller is reduced, thus ensuring the stable welding operation of the grinding roller.

[0021] Multiple sets of elastic components are provided, and the multiple sets of elastic components are arranged in a ring array between the mounting sleeve 301 and the support ring 302; It should be noted here that the elastic support effect is ensured by setting up multiple sets of elastic components.

[0022] The elastic component includes a sleeve 401 fixed on the mounting sleeve 301, a slide rod 402 slidably connected on the sleeve 401, one end of the slide rod 402 being fixed to the support ring 302, and a spring 403 being sleeved on the outside of the sleeve 401. It should be noted that the sleeve 401 and the slide rod 402 facilitate the extension and retraction guidance between the auxiliary support ring 302 and the mounting sleeve 301, and the spring 403 facilitates the elastic push of the retracted support ring 302.

[0023] The connecting transmission assembly includes multiple sets of sliding grooves 501 opened on the outside of the mounting roller 201. The multiple sets of sliding grooves 501 are arranged in a ring array on the mounting roller 201 and are arranged along the axial direction of the mounting roller 201. Sliding blocks 502 are slidably connected inside the sliding grooves 501 and are fixed inside the mounting sleeve 301. It should be noted here that during the movement of the mounting sleeve 301, the mounting roller 201 and the push rod 202 are driven to rotate through the connection between each set of sliding grooves 501 and sliding blocks 502. Furthermore, the cooperation of multiple sets of sliding grooves 501 and sliding blocks 502 facilitates the fitting of the mounting sleeve 301 onto the outer side of the mounting roller 201. During installation, the mounting sleeve 301 cannot slide further when it reaches the rightmost side of the sliding groove 501 (see...). Figure 3 (state).

[0024] Working principle: During the clamping and installation of the grinding roller to be welded, a three-jaw chuck 104 is used to clamp and fix one end of the grinding roller. After clamping, the drive component 105 drives the slide table 103 to move towards the other end of the grinding roller. During the movement, one end of the push rod 202 on the mounting roller 201 abuts against the center hole at the end of the grinding roller. Through the abutting and pressing action and the clamping action of the three-jaw chuck 104, the clamping and installation of the grinding roller is completed. After clamping and installation, the subsequent rotating component drives the rotation of the three-jaw chuck 104 to rotate the clamped grinding roller. The rotation of the grinding roller facilitates the welding operation at different positions on the grinding roller. During the rotation of the grinding roller, the abutting and pressing action between the push rod 202 and the center hole at one end of the grinding roller drives the push rod 202 and the mounting roller 201 to rotate. During the movement of the push rod 202 toward the center hole at the end of the grinding roller, the support ring 302 first abuts against the end of the grinding roller. As the push rod 202 continues to move, it pushes the support ring 302 toward the mounting sleeve 301 to retract. During this retraction, it pushes each set of sliding rods 402 to slide on each set of sleeves 401, causing the spring 403 to deform and generate elastic force. Through the elastic force of the spring 403, the support ring 302 provides elastic support to one end of the grinding roller. During the subsequent rotation of the grinding roller, the support ring 302... The grinding roller end and the support ring 302 are supported and frictionally interact, causing the support ring 302 to rotate synchronously. During the rotation of the support ring 302, the mounting sleeve 301 is driven to move synchronously through the connection between the sleeve 401 and the slide rod 402. During the movement of the mounting sleeve 301, the mounting roller 201 and the top rod 202 are driven to rotate through the connection between each set of sliding grooves 501 and the sliding block 502, reducing the probability of relative rotational deviation between the top rod 202 and the end of the grinding roller, and ensuring stable welding operation of the grinding roller.
