Description

Technical Field

[0001] This utility model belongs to the field of profile cutting technology, and specifically relates to a sinking clamping mechanism. Background Technology

[0002] Laser cutting technology, as a high-quality, high-precision, and high-efficiency processing method, has been widely used in aerospace, aviation, and automotive manufacturing. Laser tube cutting machines are the primary equipment for cutting tubes, effectively cutting square, round, and irregularly shaped tubes, offering advantages over other equipment in this area. When cutting profiles, to prevent movement and increase stability, most cutting machines have clamping mechanisms at the rear end to hold and limit the profile.

[0003] However, traditional clamping mechanisms are mostly simple support plates and pressure plates. The pressure plate moves downward to cooperate with the support plate below to achieve the clamping and limiting function of the profile. However, sometimes the profiles are different in size and appearance, and the fixed support plate cannot be used when the bottom of the profile needs to be supported upward or downward. At the same time, sometimes the clamping mechanism needs to be moved to clamp the rear end of the profile according to the length of the profile. Therefore, the above structure cannot be used to clamp and limit the profile when placing different types of profiles.

[0004] To solve the above problems, we provide a recessed clamping mechanism that can clamp and limit the profile while allowing it to move up, down, left, and right. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a sinking clamping mechanism.

[0006] The purpose of this utility model is achieved as follows: a recessed clamping mechanism includes a base frame, on which a support frame is provided. A connecting plate is provided on the upper right end of the support frame, and a clamping mechanism is provided on the connecting plate. The clamping mechanism includes an ear plate, and an ear plate is provided inside the connecting plate. A drive rod and a connecting rod are rotatably provided on the ear plate. The connection position between the connecting rod and the ear plate is located directly below the connection position between the drive rod and the ear plate. A bracket is fixedly provided on the right end of the connecting plate. A pressure plate is provided on the right end of the drive rod and the connecting rod. The pressure plate is rotatably connected to the drive rod and the connecting rod. The connection position between the drive rod and the pressure plate is located directly below the connection position between the connecting rod and the pressure plate. The drive rod can rotate around the connection position between the drive rod and the ear plate.

[0007] Furthermore, a cylinder is rotatably installed inside the connecting plate, and the output end of the cylinder is rotatably connected to the left end of the drive rod.

[0008] Furthermore, the bracket has a V-shaped opening facing upwards.

[0009] Furthermore, the support frame is located on the base frame and can move left and right.

[0010] In use, this utility model utilizes a motor to move the support frame left and right along the base frame, cooperating with the clamping mechanism to clamp profiles of different lengths, or to move the profile left and right after clamping it, thus enabling cutting at different positions. A cylinder can move the connecting plate up and down relative to the support frame to adjust the height of the bracket and pressure plate, facilitating the subsequent clamping of profiles at different placement heights.

[0011] The extension and retraction of a cylinder drives a drive rod to rotate, which in turn moves the pressure plate up and down. Since the drive rod and connecting rod are vertically distributed on both the ear plate and the pressure plate, they can move the pressure plate up and down, thus pressing and limiting the profile placed on the bracket downwards. The shape of the pressure block can be selected according to the profile's appearance. For example, for rectangular profiles, a V-shaped lower surface of the pressure block can be chosen to facilitate pressing and fixing the profile, increasing the contact area between the pressure block and the profile. Similarly, for profiles with a flat upper surface placed on the bracket, a flat lower surface of the pressure block can be chosen to facilitate pressing and fixing the profile, increasing the contact area between the pressure block and the profile. The cylinder component in this application can be replaced by other structures with lifting functions, as long as precise lifting control is achieved; no technical limitations are imposed. Furthermore, the lifting control of the cylinder is existing technology and is not subject to technical limitations.

[0012] Beneficial effects: This application can achieve recessed clamping of profiles, that is, regardless of the thickness of the profile, the lower surface of the pressure block can be parallel to the horizontal plane; at the same time, a support frame that can move left and right is provided to cooperate with the clamping mechanism of this application to clamp profiles of different lengths close together, or after clamping the profile, drive the profile to move left and right to achieve cutting functions at different positions; the connecting plate can be driven to move up and down relative to the support frame by the cylinder two to adjust the vertical height of the bracket and the pressure plate, so as to facilitate the subsequent clamping of profiles at different placement heights.

[0022] Example 1, as Figure 1 As shown in Figure 7, the purpose of this utility model is achieved as follows: a recessed clamping mechanism includes a base frame 1, on which a support frame 2 is provided. A connecting plate 3 is provided on the upper right end of the support frame 2. An ear plate 10 is provided inside the connecting plate 3. A drive rod 9 and a connecting rod 12 are rotatably provided on the ear plate 10. The connection position between the connecting rod 12 and the ear plate 10 is located directly below the connection position between the drive rod 9 and the ear plate 10. A bracket 5 is fixedly provided on the right end of the connecting plate 3. A pressure plate 4 is provided on the right end of the drive rod 9 and the connecting rod 12. The pressure plate 4 is rotatably connected to the drive rod 9 and the connecting rod 12. The connection position between the drive rod 9 and the pressure plate 4 is located directly below the connection position between the connecting rod 12 and the pressure plate 4. The drive rod 9 can rotate around the connection position between the drive rod 9 and the ear plate 10.

[0023] A cylinder 8 is rotatably mounted inside the connecting plate 3, and the output end of cylinder 8 is rotatably connected to the left end of the drive rod 9. The bracket 5 has a V-shaped opening facing upwards. The support frame 2 is located on the base frame 1 and can move left and right. A motor is mounted on the support frame 2, and the motor drives the support frame 2 to move left and right along the base frame 1.

[0024] A drive gear is provided at the motor output end, and a rack 7 is provided on the base frame 1. The drive gear and the rack 7 mesh with each other for transmission. The connecting plate 3 can move up and down relative to the support frame 2. A cylinder 13 is provided on the support frame 2. The output end of the cylinder 13 is connected to the connecting plate 3, and the cylinder 13 drives the connecting plate 3 to move up and down.

[0025] A pressure block 11 is provided on the pressure plate 4, and the lower end face of the pressure block 11 protrudes from the lower surface of the pressure plate 4. The lower surface of the pressure block 11 has a planar structure. The lower surface of the pressure block 11 has a V-shaped structure.

[0026] In use, the motor 6 drives the support frame 2 to move left and right along the base frame 1, cooperating with the clamping mechanism of this application to clamp profiles of different lengths, or to move the profiles left and right after clamping them, thereby achieving cutting functions at different positions. The cylinder 13 drives the connecting plate 3 to move up and down relative to the support frame 2, adjusting the vertical height of the bracket 5 and the pressure plate 4 to facilitate subsequent clamping of profiles at different placement heights.

[0027] The extension and retraction of cylinder 8 drives the drive rod 9 to rotate, which in turn moves the pressure plate 4 up and down. Since the drive rod 9 and connecting rod 12 are vertically distributed on the ear plate 10 and on the pressure plate 4, they can move the pressure plate 4 up and down, thus pressing and limiting the profile placed on the bracket 5 with the pressure block 11. The shape of the pressure block 11 can be selected according to the appearance of the profile. For example, for rectangular profiles, the lower surface of the pressure block 11 can be V-shaped to facilitate pressing and fixing the profile and increase the contact area between the pressure block 11 and the profile. Similarly, for profiles with a flat upper surface placed on the bracket 5, the lower surface of the pressure block 11 can also be flat to facilitate pressing and fixing the profile and increase the contact area between the pressure block 11 and the profile. The cylinder component in this application can be replaced by other structures with lifting functions, as long as they can achieve precise lifting control, without any technical limitations; and the lifting control of the cylinder is existing technology and is not subject to any technical limitations.
