Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and more specifically, to a high-precision positioning and clamping device for sheet metal processing. Background Technology

[0002] During the production and processing of the board, multiple sides of the board need to be cut according to different usage requirements. During the cutting process, clamping devices are needed to position the board and the worktable.

[0003] A search revealed an existing patent (publication number: CN221249044U) that discloses a sheet metal cutting clamping device, including a support frame, an operating table rotatably mounted on the outer side of the top end face of the support frame, a clamping auxiliary mechanism mounted on the outer side of the operating table, a spacing adjustment mechanism mounted on the inner side of the connection between the operating table and two electric push rods, an angle control mechanism mounted on the inner side of the connection between the operating table and the support frame, and a transmission rack slidably connected to the front side of the inner end of the support frame. This device enables rapid control and adjustment of the operating table and the sheet metal in different directions and angles, improving the ease of operation when cutting different sides of the sheet metal, ensuring work efficiency during sheet metal cutting, and enhancing the convenience and flexibility of clamping and cutting sheet metal. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing clamping devices are used because the plates need to be cut. If the plate size is too wide, the plate on the cutting side will be suspended in the air, resulting in some areas of the plate losing support. If the plate is not adequately supported, it is easy to bend or deform due to uneven force during cutting. In modern manufacturing environments, production tasks are often diversified and frequently change. Operators often need to perform different processing tasks frequently, which makes it inconvenient to frequently adjust the clamping when changing the clamping.

[0005] Therefore, a high-precision positioning and clamping device for sheet metal processing is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-precision positioning and clamping device for sheet metal processing, so as to solve the problems mentioned in the background art.

A support plate is provided on the left side of the upper end of the worktable. The straight rail slide is respectively provided at the front and rear ends of one side of the support plate. An mounting plate is provided at the upper end of the support plate. An electric push rod is provided at the upper end of the mounting plate. A clamping plate is provided at the output end of the electric push rod. Limit sliders are provided at the front and rear ends of one side of the clamping plate.

[0008] The front and rear ends of the right side of the workbench are provided with threaded columns. The outer surfaces of the two sets of threaded columns are fitted with connecting pipes. A telescopic rod is provided on the right side of the connecting pipe. The support panel is installed at the end of the telescopic rod away from the connecting pipe. A connecting bracket is installed at the lower end of the two sets of support panels.

[0009] Preferably, the two sets of straight rail grooves abut against the two sets of limiting sliders respectively, and the limiting sliders are rectangular in shape.

[0010] Preferably, the output end of the electric push rod is connected to the clamping plate through the mounting plate, and a pad made of rubber is installed on the lower end surface of the clamping plate.

[0011] Preferably, the threaded column and the connecting pipe are connected by a thread, and the two sets of connecting pipes are at the same horizontal level and correspond to each other.

[0012] Preferably, the connecting bracket is U-shaped, and its two ends are respectively connected to the lower end face of the support panel.

[0013] Preferably, support legs are provided at the four corners of the lower end face of the workbench, and the inclination angle of the two sets of support legs is 45 degrees.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] As attached Figures 1 to 4 The high-precision positioning and clamping device for sheet metal processing shown includes a worktable 1, a straight rail slide 3, a clamping plate 6, a telescopic rod 10 and a support panel 11. A support plate 2 is provided on the left side of the upper end of the worktable 1. The straight rail slide 3 is respectively provided at the front and rear ends of one side of the support plate 2. An mounting plate 4 is provided at the upper end of the support plate 2. An electric push rod 5 is provided at the upper end of the mounting plate 4. The output end of the electric push rod 5 is provided with the clamping plate 6. Limit sliders 7 are provided at the front and rear ends of one side of the clamping plate 6.

[0025] A telescopic rod 10 is provided on the right side of the connecting pipe 9, and a support panel 11 is installed at the end of the telescopic rod 10 away from the connecting pipe 9. A connecting bracket 12 is installed at the lower end of the two sets of support panels 11.

[0026] Specifically: When clamping the sheet metal, the electric push rod 5 adjusts the telescopic control of the clamping plate 6 to hold the sheet metal, allowing the clamping plate 6 to be precisely adjusted according to the thickness of the sheet metal during lifting and lowering, ensuring that it can adapt to sheet metal of different thicknesses during clamping. Two sets of limiting sliders 7 on one side abut against the straight rail groove 3 on one side of the support plate 2, thus playing an important guiding role. When the clamping plate 6 is lifted and lowered, the limiting sliders 7 slide in the straight rail groove 3 on one side of the support plate 2. Due to the restriction of the limiting sliders 7 in the straight rail groove 3, the clamping plate 6 can only move precisely along the predetermined path, thereby eliminating any possible lateral deviation and ensuring that the clamping plate 6 can clamp the sheet metal with high precision. Subsequently, the telescopic rod 10 and the support panel 11 are adapted to the actual size of the processed panel, and the telescopic length is adjusted according to the needs, thereby changing the actual support width, thus ensuring that the sheet metal is not subject to deformation risk during processing. The connecting bracket 12 provides a stable connection, preventing the two sets of telescopic rods 10 from rotating on their own, ensuring that they can adjust the telescopic length simultaneously, and bearing the weight of the support panel 11 and the sheet metal.

[0027] Example 2

[0028] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0029] In a preferred embodiment, the two sets of straight rail slides 3 respectively abut against the two sets of limiting sliders 7, and the limiting sliders 7 are rectangular in shape; furthermore, the straight rail slide 3 is designed as a linear track, providing a fixed and smooth sliding path, and the width and depth of the straight rail slide 3 are precisely designed to ensure that the limiting sliders 7 can move freely in it without too much gap, thereby maintaining the stability of the lifting and lowering of the clamping plate 6.

[0030] In a preferred embodiment, the output end of the electric push rod 5 is connected to the clamping plate 6 through the through mounting plate 4. A pad 61 is installed on the lower end surface of the clamping plate 6. The pad 61 is made of rubber. Furthermore, the rubber pad 61 provides a buffering and abutting effect between the clamping plate 6 and the plate, and prevents the plate from shifting during processing through the friction of the rubber material.

[0031] In a preferred embodiment, threaded posts 8 are provided at both the front and rear ends of the right side of the workbench 1. Connecting pipes 9 are sleeved on the outer surfaces of the two sets of threaded posts 8. The threaded posts 8 and the connecting pipes 9 are threadedly connected, and the two sets of connecting pipes 9 are horizontally aligned with each other. Furthermore, the connecting pipes 9 are connected to the threaded posts 8 to install a telescopic rod 10 on one side of the workbench 1. Since the joints between the telescopic rods 10 are rotatable, the connecting pipe 9 will not be unable to rotate due to the connection of the telescopic rods 10 when rotating, so that the rotating connecting pipe 9 can be disassembled from the threaded posts 8.

[0032] In a preferred embodiment, the connecting bracket 12 is U-shaped, and its two ends are respectively connected to the lower end face of the support panel 11; furthermore, the connecting bracket 12 provides an integrated connecting support function to prevent the telescopic rod 10 from shifting from the support panel 11, and to ensure that the two sets of telescopic rods 10 can extend and retract simultaneously.

[0033] In a preferred embodiment, support legs 13 are provided at the four corners of the lower end face of the workbench 1, and the inclination angle of the two sets of support legs 13 is 45 degrees. Furthermore, the support legs 13 provide support for the workbench 1, and the two sets of support legs 13 provide anti-tipping support on one side of the workbench 1 to prevent it from tipping over when the telescopic rod 10 is disassembled and used.

[0034] The working process of this utility model is as follows: First, the plate is placed on the surface of the workbench 1. The extension and retraction of the electric push rod 5 on the mounting plate 4 is adjusted, thereby driving the clamping plate 6 to rise and fall. When the clamping plate 6 rises and falls, the limiting slider 7 slides in the straight rail groove 3 on one side of the support plate 2. This is because the limiting slider 7 abuts in the straight rail groove 3, so that the clamping plate 6 can only move precisely along the predetermined path, thereby eliminating any possible lateral displacement. Then, the pad 61 of the clamping plate 6 contacts the plate for anti-slip clamping. When the size of the plate to be clamped is... When the size is large, the extension length of the two sets of telescopic rods 10 is adjusted to allow the support panel 11 to adapt to different sizes of plates. The two sets of connecting brackets 12 ensure that the telescopic rods 10 extend and retract simultaneously to support the plates on the support panel 11. When the size is insufficient to extend the telescopic rods 10, the connecting pipe 9 is rotated to remove the threaded column 8 from its outer surface for quick disassembly. The support legs 13 provide support for the worktable 1. The two sets of support legs 13 are tilted at 45 degrees to prevent the worktable 1 from tipping over. The above describes the working principle of this high-precision positioning and clamping device for plate processing.
