Description

Technical Field

[0001] This application relates to the field of clamping mechanisms, and specifically to a pressing structure for stainless steel pipe materials. Background Art

[0002] During the processing of stainless steel pipe materials, traditional methods usually use manual or mechanical pressing structures to fix the pipe materials. However, these traditional methods generally have the problem that the pipe materials cannot be effectively limited in position, resulting in the pipe materials being prone to displacement during the processing, affecting the processing accuracy and efficiency. In addition, manual operation has a high labor intensity and low safety, and it is difficult to meet the requirements of modern industrial production. Utility Model Content

[0009] A first connecting rod, one end of which is hinged to the fixing plate, the other end is hinged to a second connecting rod, and the other end of the second connecting rod is hinged to the connecting plate;

[0010] A third connecting rod, one end of which is coaxially hinged to the first connecting rod and the second connecting rod, the other end is hinged to the telescopic end of a cylinder, the cylinder is fixedly installed on the fixing plate, the cylinder drives the third connecting rod to move, when the third connecting rod moves to the horizontal position, the first connecting rod and the second connecting rod are collinear and both are perpendicular, pushing the connecting plate, so that the two clamping blocks form a clamping of the pipe material.

[0026] To solve the technical problems in the background art, as Figure 1-2 shown, the present application provides a technical solution: a pressing structure for stainless steel pipe materials, characterized as follows:

[0027] It includes a fixed seat (1), a lead screw (3), a lead screw nut (4), a connecting plate (5), a clamping block (6), a first connecting rod (7), a second connecting rod (8), a third connecting rod (9) and a cylinder (10). The fixed seat (1) is composed of two upper and lower fixing plates (2). The fixing plates (2) are horizontally arranged and used to provide stable support for the entire pressing structure. Two lead screws (3) are respectively vertically connected to both ends of the two fixing plates (2) to form an enclosing structure. The function of the lead screw (3) is to transmit the rotational movement of the lead screw nut (4), thereby driving the movement of the connecting plate (5). The lead screw nut (4) is sleeved on the lead screw (3), and the lead screw nut (4) is fixedly connected to the connecting plate (5). The connecting plate (5) is arranged parallel to the fixing plate (2) and moves along with the movement of the lead screw nut (4). In this way, when the lead screw nut (4) is stressed, the connecting plate (5) can move vertically under the drive of the lead screw nut (4). Moreover, compared with an ordinary stainless steel pipe, the lead screw (3) has threads, and in cooperation with the lead screw nut (4), the up and down movement of the connecting plate (5) is more precise and smooth. The clamping block (6) is arranged on the connecting plate (5) and is used to clamp the stainless steel pipe material. The specific structure of the clamping block (6) can be a metal block with a certain hardness and wear resistance, and its surface is provided with protrusions or grooves to increase the friction with the pipe material. One end of the first connecting rod (7) is hinged to the fixing plate (2), and the other end is hinged to the second connecting rod (8). The other end of the second connecting rod (8) is hinged to the connecting plate (5). In this way, when the first connecting rod (7) and the second connecting rod (8) move, the connecting plate (5) can follow the movement, and the first connecting rod (7) and the second connecting rod (8) play a role in transmitting power. One end of the third connecting rod (9) is coaxially hinged to the first connecting rod (7) and the second connecting rod (8), that is, the hinge axis of the first connecting rod (7) and the second connecting rod (8) is the same hinge axis, and the first connecting rod (7), the second connecting rod (8) and the third connecting rod (9) are jointly hinged at a hinge point. The other end of the third connecting rod (9) is hinged to the telescopic end of the cylinder (10). The cylinder (10) is fixedly installed on the fixing plate (2), and can be installed on one side of the fixing plate (2) adjacent to the connecting plate (5), or can be installed on the side of the fixing plate (2) facing away from the connecting plate (5). If it is installed on the side of the fixing plate (2) facing away from the connecting plate (5), the telescopic end of the cylinder (10) passes through the fixing plate (2) and is connected to the third connecting rod (9). The cylinder (10) is used to drive the movement of the third connecting rod (9). When the telescopic end of the cylinder (10) expands and contracts, the third connecting rod (9) moves accordingly, thereby driving the first connecting rod (7) and the second connecting rod (8) to move. When the third connecting rod (9) moves to the horizontal position, the first connecting rod (7) and the second connecting rod (8) are collinear and perpendicular. At this time, the first connecting rod (7) and the second connecting rod (8) push the connecting plate (5), so that the two clamping blocks (6) form a clamp on the stainless steel pipe material. By controlling the action of the cylinder (10), the clamping and loosening of the pipe material by the clamping block (6) can be realized.

[0028] It should be noted that the clamping block (6) as shown in the figure has an arc surface (11), and this arc surface (11) is designed to fit the pipe material. Specifically, the arc surface (11) of the clamping block (6) is arc-shaped, and its radius of curvature matches the diameter of the pipe material to ensure that the clamping block (6) can closely fit the surface of the pipe material, thereby providing a stable clamping effect.

[0029] Furthermore, two clamping blocks 6 form a pair, which are respectively arranged on the fixed plate 2 and the connecting plate 5 and are arranged facing each other. They can be fixed by bolts, welded, or snap-connected to make the clamping blocks 6 closely fit the fixed plate 2 and the connecting plate 5. The positions of the clamping blocks 6 are aligned facing the pipe material to form a clamping of the pipe material. At this time, the gap between the two clamping blocks 6 is the passage of the pipe material. By operating the cylinder 10 to control the movement of the connecting plate 5 relative to the fixed plate 2, the two clamping blocks 6 tightly clamp the pipe material, thereby realizing the fixation of the pipe material.

[0030] It should be noted that the anti-slip rubber pad is arranged on the arc surface (11), and its shape matches the arc surface (11) to ensure that there is no gap between the rubber pad and the arc surface (11). The anti-slip rubber pad (12) is made of high-elastic rubber, which has good anti-slip performance and wear resistance, and can enhance the clamping force on the pipe material.

[0031] Furthermore, the clamping blocks (6) are arranged in pairs and multiple pairs are provided. Multiple pipe materials can be clamped simultaneously, improving production efficiency.

[0032] It should be noted that the core part of the present utility model is the clamping block (6), which has multiple different enclosed inner diameters; for example, there are three specifications of A, B, and C respectively. Specifically as follows: Clamping block A: The enclosed inner diameter is φ10mm, which is suitable for clamping small workpieces. Clamping block B: The enclosed inner diameter is φ20mm, which is suitable for clamping medium-sized workpieces. Clamping block C: The enclosed inner diameter is φ30mm, which is suitable for clamping large workpieces. The function of setting different enclosed inner diameters is to clamp multiple pipe materials of different sizes simultaneously.

[0033] It should be noted that the clamping block (6) is detachable. The clamping block (6) is connected to the fixed plate (2) and the connecting plate (5) by bolts or snap connections, so that the clamping block (6) can be easily disassembled and installed. Users can selectively install the clamping block (6) according to different needs.

[0034] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
