Description

Technical Field

[0001] This application relates to the field of shaft machining technology, specifically a support structure for an electromagnetic centerless clamp. Background Technology

[0002] Electromagnetic centerless chucks are widely used in the precision grinding of parts such as bearing rings. Their working principle involves using magnetic force to hold the workpiece in place, and positioning and supporting it through two fixed support points and one swinging support point. By adjusting the position of the support points, the machining allowance of the workpiece can be controlled, thereby achieving extremely high machining accuracy.

[0003] However, in existing technologies, the arc-shaped disk is usually directly fixed to the frame on one side of the magnetic chuck. This fixing method makes it impossible to flexibly adjust the position of the arc-shaped disk according to the actual length of the workpiece and processing requirements. When processing long shaft workpieces, the fixed position of the arc-shaped disk greatly limits the adjustment distance of the support plate on it, making it impossible to effectively support different positions of the long shaft workpiece. During processing, long shaft workpieces are prone to shaking or deformation due to the lack of sufficient and suitable support, which leads to a significant reduction in the processing accuracy of long shaft workpieces, making it difficult to meet the accuracy requirements of actual production. Therefore, this application proposes a support structure for an electromagnetic centerless clamp to solve this problem. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the existing defects and provide a support structure for an electromagnetic centerless clamp, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a support structure for an electromagnetic centerless clamp, comprising two arc-shaped disks, wherein the arc-shaped disks are connected to a linear guide rail pair mounted on the side of the frame via a mounting bracket and can slide in a direction perpendicular to the workpiece axis. The arc-shaped disks are connected to a support plate via two slide blocks, and the two slide blocks are at a certain angle. A positioning structure is provided between the two slide blocks of one of the arc-shaped disks to ensure that the installation positions of the slide blocks on the two arc-shaped disks are consistent.

[0006] Furthermore, the positioning structure is an open positioning block, with its two sides corresponding to the slide block, and guide wheels that restrict the position of the open positioning block are installed on its inner side.

[0007] Furthermore, the opening positioning block is fixed in the arc-shaped groove of the arc-shaped disk by bolts and T-shaped blocks.

[0008] Furthermore, the linear guide pair consists of a guide rail and a slider, the guide rail being fixed on the frame, and the slider being fixedly connected to the mounting bracket.

[0009] Furthermore, the slide has a groove for positioning the support plate, and the support plate is fixed to the slide with bolts.

[0010] Furthermore, the support plate has a strip-shaped hole for accommodating bolts, and the length direction of the strip-shaped hole is consistent with the length direction of the support plate.

[0011] Furthermore, the arc-shaped disk is provided with an arc-shaped groove centered at its midpoint. The slide block is slidably connected to the arc-shaped groove via a T-shaped block, and the fastening bolts and the T-shaped block are installed on the arc-shaped disk.

[0012] Furthermore, a carbide support head is installed at the end of the support plate.

[0013] Compared with the prior art, this application connects the arc-shaped disk to the linear guide pair through the mounting bracket, so that the arc-shaped disk can slide in a direction perpendicular to the workpiece axis, effectively expanding the adjustment range of the arc-shaped disk, thereby expanding the support distance of the support plate. Moreover, by setting two arc-shaped disks, long shaft workpieces can be effectively supported, improving the machining accuracy of long shaft workpieces. Furthermore, the positioning structure facilitates the adjustment of the slides on the two arc-shaped disks by the worker, ensuring that the angle of the support plate is consistent.

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0017] Please see Figure 1-3 This application provides a technical solution for a support structure for an electromagnetic centerless clamp: a support structure for an electromagnetic centerless clamp includes an arc-shaped disk 6, and the arc-shaped disk 6 is connected to a support plate 9 through two sliding blocks 8.

[0018] The arc-shaped disk 6 is provided with an arc-shaped groove 7 centered at its midpoint. The slide block 8 is slidably connected to the arc-shaped groove 7 through a T-shaped block, and the fastening bolt and the T-shaped block are installed on the arc-shaped disk 6, and the two slide blocks 8 are at a certain angle.

[0019] Loosen the fastening bolts of the fixed slide block 8 so that the slide block 8 can slide in the arc groove 7 of the arc plate 6, thereby adjusting the angle between the two slide blocks 8, so that the carbide support head on the support plate 9 can support shafts of different sizes.

[0020] The slide 8 has a groove for positioning the support plate 9, and the support plate 9 is fixed to the slide 8 by bolts.

[0021] Furthermore, the support plate 9 has a strip-shaped hole for accommodating bolts, and the length direction of the strip-shaped hole is consistent with the length direction of the support plate 9, so that it has a certain position adjustment margin during installation, which can be matched with the groove on the slide 8 to adjust the length of the support plate 9 extending out of the slide 8.

[0022] Furthermore, a carbide support head is installed at the end of the support plate 9 to directly support the workpiece. It has high hardness and good wear resistance.

[0023] There are two arc-shaped disks 6, and the arc-shaped disks 6 are connected to the linear guide rail pair 5 installed on the side of the frame 1 through the mounting bracket 2, and can slide in a direction parallel to the axis of the workpiece. This direction is parallel to the axis of the workpiece and is used to realize the coarse feed of the support structure in the radial direction.

[0024] The linear guide pair 5 consists of a guide rail 501 and a slider 502. The guide rail 501 is fixed on the frame 1, and the slider 502 is fixedly connected to the mounting bracket 2.

[0025] A positioning structure is provided between the two slides 8 on the right-hand arc-shaped disk 6 to ensure that the installation positions of the slides 8 on the two arc-shaped disks 6 are consistent.

[0026] Furthermore, the positioning structure is an open positioning block 3, with the two sides of the open positioning block 3 corresponding to the slide block 8. A guide wheel 4 is installed on the inner side of the open positioning block 3 to limit the position of the open positioning block 3. Positioning is achieved by the side of the open positioning block 3 contacting the side of the slider 8 of the two arc-shaped disks 6. Then, the bolts fixing the slide block 8 can be tightened.

[0027] Furthermore, the opening positioning block 3 is fixed in the arc-shaped groove 7 of the arc-shaped disk 6 by bolts and T-shaped blocks. The guide wheel 4 and T-shaped blocks can effectively guide the opening positioning block 3 and improve the installation accuracy of the slide blocks 8 on the two arc-shaped disks 6.

[0028] When using this electromagnetic centerless clamp: First, adjust the support plates 9 on the four slides 8 to ensure they extend to the same height, so that the four support plates 9 can contact and support long shaft workpieces. Then, install the slide blocks 8 sequentially on the arc-shaped disk 6, and loosen the T-blocks and bolts. Next, adjust the angles of the two slide blocks 8 on the arc-shaped disk 6 near the electromagnet and fix them. Then, move the two mounting brackets 2 closer to each other along the guide rail 501, adjust the side of the opening positioning block 3 on the right arc-shaped disk 6 so that it can contact the side of the slide block 8 on the left arc-shaped disk 6, and fix the opening positioning block 3. Then, tighten the bolts on the slide block 8 on the right arc-shaped disk 6 to fix it on the arc-shaped disk 6. Then, operate the opening positioning block 3 to fix the other slide block 8 on the right arc-shaped disk 6, ensuring that the positions of the slide blocks 8 on the two arc-shaped disks 6 are consistent.

[0029] First, based on the length of the long shaft workpiece to be processed and the processing requirements, the positions of the two arc-shaped disks 6 on the frame 1 are adjusted by the linear guide pair 5. Since the arc-shaped disks 6 are connected to the slider 502 of the linear guide pair 5 through the mounting bracket 2, the slider 502 can slide along the guide rail 501, thereby driving the arc-shaped disks 6 to slide in a direction parallel to the workpiece axis, realizing the adjustment of the position of the arc-shaped disks 6, so that the two arc-shaped disks 6 can support the long shaft workpiece. Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
