Abstract

This utility model provides a fixture for machining plate-shaped parts, including a worktable and multiple sets of clamping devices arranged symmetrically at intervals around the upper surface of the worktable. Each clamping device includes a base, a side clamping assembly, and a vertical clamping assembly. The base is slidably mounted on the upper surface of the worktable, with one end of the upper surface of the base adjacent to the plate-shaped part for supporting and placing the part. The side clamping assembly is mounted on the base and clamps the sides of the plate-shaped part. The vertical clamping assembly is mounted on the top of the base and applies a downward clamping force to the upper surface of the plate-shaped part. The base and the upper surface of the worktable form a sliding connection that allows the fixture to move closer to or further away from the center of the worktable. This allows the fixture to adjust its installation position on the worktable according to the size of the sheet metal, improving its flexibility and enabling the clamping of parts made of different sheet metals.

Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically to a jig for processing plate-shaped parts. Background Technology

[0002] During machining processes such as drilling and milling, sheet metal parts are prone to vibration, twisting, bouncing, or even displacement due to the cutting force of the drill bit. This can adversely affect the machining accuracy of the sheet metal and the cutting tool. To address this, a fixture is needed to clamp the sheet metal. The function of the fixture is to provide sufficient and stable clamping force to firmly fix the sheet metal parts, resist the cutting force, and prevent the above phenomena from occurring.

[0003] In the relevant prior art, the fixture used for clamping sheet metal parts is a vise. Multiple vise fixtures are installed on the worktable, and the sheet metal parts are clamped and positioned by clamping the outer edges of the sheet metal parts. Although the vise can clamp the sheet metal, its flexibility is poor because the position of the vise on the worktable is fixed, and it cannot clamp and position sheet metal parts of different sizes. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a jig for processing plate-shaped parts, so as to solve the problem of poor flexibility caused by the use of vise jigs in existing plate-shaped parts jigs.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] This application provides a fixture for machining plate-shaped parts, including a worktable and multiple sets of clamping devices disposed on the worktable. The multiple sets of clamping devices are symmetrically spaced around the upper surface of the worktable. Each clamping device includes a base, a side clamping assembly, and a vertical clamping assembly. The base is slidably mounted on the upper surface of the worktable. One end of the upper surface of the base adjacent to the plate-shaped part is used to support and place the plate-shaped part. The side clamping assembly is mounted on the base and is used to clamp the side of the plate-shaped part. The vertical clamping assembly is mounted on the top of the base and is used to apply a downward clamping force to the upper surface of the plate-shaped part.

[0007] Furthermore, the base includes a flat sliding part, a support part extending vertically upward from the sliding part, and a mounting part extending vertically upward from the outer edge of the sliding part and horizontally extending towards the center of the worktable. The upper end of the sliding part is used to support and place a plate-shaped part near the end of the worktable. A receiving space is formed between the bottom of the mounting part and the upper end of the support part to accommodate the side clamping assembly. The vertical clamping assembly is installed on the mounting part at the end near the center of the worktable.

[0008] Furthermore, the side clamping assembly includes a side pressure cylinder and a side pressure block. The side pressure cylinder is fixedly installed on the bottom outer edge of the mounting part. The side pressure cylinder is fixedly connected to the side pressure block through a piston rod. The side pressure block is slidably installed on the upper end surface of the sliding part. The side pressure block is used to clamp the side of the plate-shaped part.

[0009] Furthermore, the vertical pressing assembly includes a pressing cylinder and a pressing block. The pressing cylinder is fixedly installed on the upper surface of the mounting part near the center of the worktable. The pressing block is horizontally disposed below the end of the mounting part near the center of the worktable. The pressing cylinder is fixedly connected to the pressing block through a piston rod. The pressing cylinder is used to drive the pressing block to move up and down.

[0010] Furthermore, a rubber plate is fixedly installed on the lower surface of the pressing block.

[0011] Furthermore, the lower surface of the rubber sheet is provided with anti-slip grooves evenly spaced along its length.

[0012] Furthermore, the bottom end face of the sliding part is provided with a pair of sliding grooves that are closer to or farther away from the center of the worktable. The pair of sliding grooves are arranged symmetrically. The upper end face of the worktable is provided with a slide rail that slides in cooperation with the pair of sliding grooves. The left and right sides of the sliding part are respectively provided with elongated holes parallel to the length direction of the sliding groove. The worktable is provided with a plurality of threaded holes evenly spaced along the length direction of the sliding groove on the left and right sides outside the sliding groove. The sliding part is fixedly installed in the threaded holes by bolts passing through the elongated holes.

[0013] Compared with existing technologies, the beneficial technical effects of this solution are as follows:

[0014] 1. The base of the clamping device and the upper surface of the worktable form a sliding connection that can move closer to or away from the center of the machining table. This allows the clamping device to be adjusted in its installation position on the machining table according to the size of the sheet metal, improving its flexibility and enabling the clamping of parts made of different sheet metals.

[0015] 2. The side clamping assembly and the vertical clamping assembly can adjust their extension and retraction according to the size and thickness of the sheet metal parts. In scenarios where fine adjustments to their respective clamping positions are required, the sheet metal parts can be clamped conveniently and quickly through the large-range adjustment (coarse adjustment) of the clamping device and the fine adjustment (fine adjustment) of the side clamping assembly and the vertical clamping assembly.

Detailed Implementation

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] See Figure 1 and Figure 2 As shown, this embodiment provides a plate-shaped part processing fixture 100, including a worktable 10 and multiple sets of clamping devices 20 disposed on the worktable 10. The multiple sets of clamping devices 20 are symmetrically spaced around the upper end face of the worktable 10 to clamp the outer edges of the plate-shaped part 200 placed on the upper end face of the worktable 10.

[0027] Continue to refer to Figure 1 and Figure 2 As shown, in this embodiment, the clamping device 20 includes a base 21, a side clamping assembly 22, and a vertical clamping assembly 23. The bottom end face of the base 21 is slidably mounted on the upper end face of the worktable 10, and the base 21 can slide relative to the worktable 10 in a direction close to or away from the center of the worktable 10. The upper end face of the base 21 at the end near the center of the worktable 10 is used to support and place the plate-shaped part 200 to be processed, that is, the bottom end of the plate-shaped part 200 is placed on the upper end face of the inner side of the base 21. The side clamping assembly 22 is mounted on the base 21 and is used to clamp the side of the plate-shaped part 200. The vertical clamping assembly 23 is mounted on the top of the base 21 and is used to apply a downward clamping force to the upper end face of the plate-shaped part 200.

[0028] By evenly spaced clamping devices 20 around the worktable 10, and the base 21 of the clamping device 20 forming a sliding connection with the upper surface of the worktable 10 that can move closer to or away from the center of the worktable, the clamping device 20 can flexibly adjust its installation position according to the external dimensions of the clamped plate-shaped part 200 when clamping it. That is, when the external dimensions of the clamped plate-shaped part 200 are large, the clamping device 20 can slide outward along the worktable 10; conversely, when the external dimensions of the clamped plate-shaped part 200 are small, the clamping device 20 slides inward along the worktable 10. This gives the clamping device 20 excellent flexibility, thereby enabling the clamping of different plate parts.

[0029] Reference Figure 2 and Figure 3 As shown, in this embodiment, the base 21 includes a flat sliding part 211, a support part 212 extending vertically upward from the sliding part 211, and a mounting part 213 extending vertically upward from the outer edge of the sliding part 211 and horizontally towards the center of the worktable 10. The bottom end of the sliding part 211 is slidably connected to the upper end surface of the worktable 10. Specifically, a pair of sliding grooves 2112 are provided at the bottom end of the sliding part 211, and a slide rail is provided on the upper end surface of the worktable 10 to slide in cooperation with the pair of sliding grooves 2112. Through the cooperation of the slide rail and the sliding grooves 2112, the sliding part 211 can slide on the worktable 10, and the installation position of the clamping device 20 on the worktable 10 can be adjusted.

[0030] The sliding part 211 has elongated holes 2111 on its left and right sides, with the direction of the elongated holes 2111 parallel to the direction of the slide groove 2112. Multiple threaded holes, evenly spaced along the length of the slide groove, are located on the left and right sides of the worktable 10 on the outer side of the slide groove. The sliding part 211 is fixedly installed in the threaded holes by bolts passing through the elongated holes 2111. When the installation position of the clamping device 20 needs to be adjusted, the sliding part 211 is slid to the corresponding position, and the position of the sliding part 211 can be finely adjusted back and forth through the elongated holes 2111 to achieve the required adjustment position. Then, by tightening the bolts, the sliding part 211 is fixedly installed on the worktable 10.

[0031] Continue to refer to Figure 2 As shown, the upper end of the sliding part 211 is close to the end of the worktable 10 for supporting and placing the plate-shaped part 200. The bottom of the mounting part 213 and the upper end of the support part 212 form a receiving space 214 for accommodating the side clamping assembly 22. The vertical clamping assembly 23 is installed on the mounting part 213 at the end near the center of the worktable 10.

[0032] Specifically, the side clamping assembly 22 includes a side pressure cylinder 221 and a side pressure block 222. The side pressure cylinder 221 is fixedly installed on the bottom outer edge of the mounting part 213. The side pressure cylinder 221 is fixedly connected to the side pressure block 222 through a piston rod. The side pressure block 222 is slidably installed on the upper end face of the sliding part 211. The side pressure block 222 is used to clamp the side of the plate-shaped part 200.

[0033] The vertical clamping assembly 23 includes a pressing cylinder 231 and a pressing block 232. The pressing cylinder 231 is fixedly installed on the upper surface of the mounting part 213 near the center of the worktable 10. The pressing block 232 is horizontally arranged below the end of the mounting part 213 near the center of the worktable 10. The pressing cylinder 231 is fixedly connected to the pressing block 232 through a piston rod. The pressing cylinder 231 is used to drive the pressing block 232 to move up and down.

[0034] The side clamping assembly 22 and the vertical clamping assembly 23 can adjust their extension and retraction according to the size and thickness of the sheet metal parts. In scenarios where fine adjustments to their respective clamping positions are required, the sheet metal parts can be clamped conveniently and quickly through the large-range adjustment (coarse adjustment) of the clamping device 20 and the fine adjustment (fine adjustment) of the side clamping assembly 22 and the vertical clamping assembly 23.

[0035] Reference Figure 2 and Figure 4As shown, to prevent damage during the pressing process on the upper surface of the plate-shaped part 200, a rubber plate 233 is fixedly installed on the lower surface of the lower pressure block 232. The elasticity and cushioning properties of the rubber plate 233 provide protection for the plate-shaped part 200. Furthermore, to prevent the rubber plate 233 from sliding during the pressing process against the upper surface of the plate-shaped part 200, anti-slip grooves 234 are evenly spaced along its length on the bottom surface of the rubber plate 233.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
