Description

Technical Field

[0001] This utility model relates to the technical field of sheet metal processing, and specifically provides a sheet metal calibration device. Background Technology

[0002] For the processing of sheet materials, it is usually necessary to calibrate and position the sheet material to prevent it from becoming skewed, and also to ensure that the sheet material is in the preset feeding position. After that, the sheet material is cut, drilled, grooved, milled, and engraved.

[0003] Current calibration devices for sheet materials include a baffle on one side of the sheet material and a pusher on the other side. The pusher is driven by a cylinder or other drive components to move, thereby pushing the sheet material closer to and in contact with the baffle to calibrate the sheet material. However, this method requires a long stroke of the cylinder in the width direction of the sheet material, which occupies a large space and is not conducive to reducing costs. Utility Model Content

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the existing plate calibration device has a long travel distance in the width direction of the plate.

[0005] In a first aspect, the present invention provides a plate calibration device, comprising: a frame; two push plates, respectively located on both sides of the plate along a second direction; and a clamping mechanism, comprising a driving member, a lead screw, a moving member, and a first connecting rod and a second connecting rod.

The first connecting rod and the second connecting rod are provided on both sides of the lead screw along the second direction, and the first connecting rod and the second connecting rod on both sides are symmetrically arranged along the lead screw.

[0006] By adopting the above technical solution, after the lead screw rotates, it can drive the moving part to move along the lead screw, thereby driving the first connecting rod and the second connecting rod to move, changing the straight distance of the first hinge shaft from the lead screw in the second direction, thereby changing the distance between the two push plates in the second direction, thereby clamping the plate located between the two push plates and completing the calibration of the plate position.

[0007] In a specific embodiment of the above-mentioned plate calibration device, the clamping mechanism further includes a support rod, which is arranged along the second direction, slidably connected to the lead screw and symmetrically arranged along the lead screw, and slidably connected to the two first connecting rods or the two second connecting rods respectively.

[0009] In a specific embodiment of the above-mentioned plate calibration device, a first groove is provided on the first connecting rod along the length direction of the first connecting rod, and a second groove is provided on the second connecting rod along the length direction of the second connecting rod. The first hinge shaft passes through the first groove and the second groove and can be fixed in relative position with the first connecting rod and the second connecting rod.

[0010] By adopting the above technical solution, the first hinge shaft can move within the first and second slide grooves to change the hinge point of the first and second connecting rods. When the moving parts move the same distance, the moving distance of the first hinge shaft in the second direction can be changed, thereby adjusting the stroke of the push plate to adapt to different sizes of plates.

[0012] By adopting the above technical solution, using the first fixing bolt to fix the first fixing piece to the first connecting rod and using the second fixing bolt to fix the second fixing piece to the second connecting rod, it is possible to ensure that the position of the first hinge shaft on the first and second connecting rods remains unchanged.

[0013] In a specific embodiment of the above-mentioned plate calibration device, the frame is provided with a guide rail extending in the second direction, and the push plate slides in cooperation with the guide rail.

[0014] By adopting the above technical solution, the movement of the push plate can be guided by the sliding cooperation between the push plate and the guide rail.

[0032] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] To address the issue of excessive travel distance in the width direction of existing sheet metal calibration devices, this invention provides a sheet metal calibration device, such as... Figure 1 As shown, the plate calibration device includes a frame 1, a push plate 2 and a clamping mechanism 3. The plate is placed on the frame 1, the push plate 2 is set on both sides of the plate along the second direction Y, and the clamping mechanism 3 is used to drive the two push plates 2 to move along the second direction Y to calibrate the position of the plate.

[0034] A support wheel assembly 11 is provided on the frame 1. The support wheel assembly 11 includes an axle and multiple rollers. The axle is arranged along the second direction Y and is rotatably connected to the frame 1. The rollers are spaced apart on the axle. The sheet material is placed on the support wheel assembly 11 to reduce the friction force when the sheet material moves along the first direction X.

[0035] A guide rail 12 is provided on the frame 1, extending along the second direction Y, and the push plate 2 slides in cooperation with the guide rail 12. During the process of the clamping mechanism 3 driving the push plate 2 to move along the second direction Y, the guide rail 12 can ensure the stability of the push plate 2 moving along the second direction Y.

[0036] To reduce damage to the material caused by excessive clamping of the push plate 2, a contact plate 21 is provided in at least one embodiment. The contact plate 21 is located inside the push plate 2, i.e., closer to the material. A buffer spring 22 is provided between the contact plate 21 and the push plate 2. The contact plate 21 can also be slidably connected to the guide rail to ensure the stability of movement. During the calibration of the material position, after the contact plate 21 contacts the material, the push plate 2 continues to move, and the spring will be compressed, reducing the possibility of damaging the material.

[0037] In addition, a telescopic component 23 can be provided between the push plate 2 and the clamping mechanism 3. The telescopic component 23 extends and retracts along the second direction Y. One end of the telescopic component 23 is fixedly connected to the push plate 2, and the other end is fixedly connected to the clamping mechanism 3. By adjusting the length of the telescopic component 23, the distance between the plate and the clamping mechanism 3 can be changed, so as to adjust the calibration position of the plate and improve the adaptability of the plate calibration device to plates of different widths.

[0038] like Figure 3 and Figure 4As shown, the clamping mechanism 3 is located below the support wheel assembly 11 and includes a drive member 31, a lead screw 32, a moving member 33, a first connecting rod 34, and a second connecting rod 35. The lead screw 32 extends along the first direction X and is rotatably connected to the frame 1. The moving member 33 is threadedly connected to the lead screw 32. The first end of the first connecting rod 34 is hinged to the moving member 33. The first end of the second connecting rod 35 is hinged to the frame 1, and the second end of the first connecting rod 34 is hinged to the second end of the first connecting rod 35. The first hinge shaft 37 of the first connecting rod 34 and the second connecting rod 35 is connected to the push plate 2. The drive member 31 is fixed to the frame 1 and is used to drive the lead screw 32 to rotate. The first connecting rod 34 and the second connecting rod 35 are provided on both sides of the lead screw 32 along the second direction Y, and the first connecting rod 34 and the second connecting rod 35 on both sides of the lead screw 32 are symmetrically arranged along the lead screw 32. After the lead screw 32 rotates, it drives the moving part 33 to move along the lead screw 32, thereby driving the first connecting rod 34 and the second connecting rod 35 to move. This changes the linear distance of the first hinge shaft 37 from the lead screw 32 in the second direction Y, thereby changing the distance between the two push plates 2 in the second direction Y, clamping the plate material located between the two push plates 2, and completing the calibration of the plate material position. In other words, the clamping mechanism 3 converts the stroke of the moving part 33 in the first direction X into the stroke of the two first hinge shafts 37 in the second direction Y through the first connecting rod 34 and the second connecting rod 35, thereby reducing the stroke of each first hinge shaft 37 in the second direction Y and simplifying the structure.

[0039] For example, the telescopic component 23 is fixedly connected to the first hinge shaft 37.

[0040] For example, the clamping mechanism 3 also includes a support rod 36, which is arranged along the second direction Y, slidably connected to the lead screw 32 and symmetrically arranged along the lead screw 32, and slidably connected to either the two first connecting rods 34 or the two second connecting rods 35. During the rotation of the lead screw 32 to drive the moving member 33 to move along the first direction X, the second connecting rods 35 will tilt, and the support rod 36 will slide relative to the second connecting rods 35, and also relative to the lead screw 32, to support the two second connecting rods 35, ensuring that the two second connecting rods 35 always maintain the same angle, that is, ensuring that the two second connecting rods 35 are always symmetrically arranged along the lead screw 32.

[0041] In some embodiments of this invention, the maximum stroke of the push plate 2 can be changed by adjusting the hinge point of the first connecting rod 34 and the second connecting rod 35. For example, the first connecting rod 34 has a first sliding groove 341 arranged along its length, and the second connecting rod 35 has a second sliding groove 351 arranged along its length. The first hinge shaft 37 passes through the first sliding groove 341 and the second sliding groove 351 and can be fixed in relative position with the first connecting rod 34 and the second connecting rod 35. The first hinge shaft 37 can move within the first sliding groove 341 and the second sliding groove 351 to change the hinge point of the first connecting rod 34 and the second connecting rod 35. When the moving member 33 moves the same distance, the moving distance of the first hinge shaft 37 in the second direction Y can be changed, thereby adjusting the stroke of the push plate 2 to adapt to different sizes of plates. Wherein, when the position of the moving member 33 remains unchanged, the farther the first hinge shaft 37 is from the lead screw 32, the greater the stroke of the clamping mechanism 3 in the second direction Y.

[0042] To facilitate the fixing of the first hinge shaft 37 to the first connecting rod 34 and the second connecting rod 35, in some embodiments of this utility model, a first fixing plate 342 and a second fixing plate 352 are provided. The first hinge shaft 37 passes through the first fixing plate 342 and the second fixing plate 352. The first fixing plate 342 is provided with a first fixing bolt 343 passing through the first sliding groove 341, and the second fixing plate 352 is provided with a second fixing bolt 353 passing through the second sliding groove 351. By fixing the first fixing plate 342 to the first connecting rod 34 with the first fixing bolt 343 and fixing the second fixing plate 352 to the second connecting rod 35 with the second fixing bolt 353, the position of the first hinge shaft 37 on the first connecting rod 34 and the second connecting rod 35 can be kept unchanged.

[0043] In summary, the working principle of this utility model is as follows:

[0044] The plate is placed on the frame 1. The drive unit 31 is started to drive the lead screw 32 to rotate, which drives the moving part 33 to move along the lead screw 32, thereby driving the first connecting rod 34 and the second connecting rod 35 to move. This changes the straight distance of the first hinge shaft 37 from the lead screw 32 in the second direction Y, thereby changing the distance between the two push plates 2 in the second direction Y, and clamping the plate located between the two push plates 2 to complete the calibration of the plate position.

[0045] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
