Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a clamping mechanism and a clamping device for semi-trailers. Background Technology

[0002] In the semi-trailer manufacturing industry, especially in the production and assembly of semi-trailer frames, frame flipping is a common and critical process. To enable subsequent operations such as welding, painting, and accessory installation, the heavy and massive frame needs to be stably clamped and precisely flipped.

[0003] Currently, the common practice in the industry is to use clamping devices. However, in existing clamping structures, the clamping end face that contacts the semi-trailer frame is usually a simple planar structure. With the planes in contact, all the clamping force is concentrated on the contact area. During subsequent flipping, this area of ​​the semi-trailer is prone to deformation. Utility Model Content

[0004] The purpose of this utility model is to provide a clamping mechanism and a clamping device for semi-trailers, which solves the technical problem that the clamping mechanism in the prior art is prone to deformation after clamping the semi-trailer frame.

[0005] This application discloses a clamping mechanism, including: Support base; A clamping drive mechanism is mounted on the support base; Multiple clamping blocks are installed on the movable end of the clamping drive mechanism, and the clamping blocks move towards each other or away from each other under the drive of the clamping drive mechanism. The clamping side of the clamping block is an inclined surface.

[0006] This application designs the clamping side of the clamping block as an inclined surface to reduce the contact area and prevent the semi-trailer frame from deforming during the flipping process.

[0007] Based on the above technical solution, the present application can be further improved as follows: Furthermore, the clamping blocks consist of four blocks, divided into a first group and a second group; The first group includes two clamping blocks located on the outer side, and the inner side of each clamping block is an inclined surface; The second group includes two clamping blocks located on the inner side, and the outer side of each clamping block is an inclined surface; There are two clamping drive mechanisms arranged side by side. One of the clamping drive mechanisms drives the first group to move, and the other clamping drive mechanism drives the second group to move. The advantage of this step is that multiple clamping blocks can achieve clamping and positioning on the outside first, and then clamping on the inside, so as to be applicable to frames of different sizes.

[0008] Furthermore, a support plate is installed on the side of the clamping drive mechanism. The advantage of this step is that the support plate can support the semi-trailer frame, thereby facilitating subsequent clamping and flipping.

[0009] Furthermore, the bottom of the clamping block is provided with a clamping groove that cooperates with the support plate. The advantage of this step is that the clamping groove facilitates the back-and-forth movement of the clamping block.

[0010] Furthermore, it also includes a mounting base, which has a groove that mates with the support base. The advantage of this step is that the mounting base facilitates assembly with other components.

[0011] Furthermore, the groove is inverted T-shaped, which facilitates the movement of the support base.

[0012] Furthermore, a push cylinder is installed on the mounting base, and the piston rod end of the push cylinder is connected to the clamping block. The beneficial effect of this step is that the push cylinder provides the motion power for the clamping block.

[0013] This application also discloses a clamping device for a semi-trailer, comprising: support; At least three of the aforementioned clamping mechanisms are mounted on the bracket and are used to clamp the main beams of the semi-trailer frame.

[0014] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages: 1. This application designs the clamping surface of the clamping block to be inclined, so as to avoid deformation of the semi-trailer frame when it is flipped after clamping.

[0015] 2. The clamping blocks in this application consist of four blocks, divided into two groups, which can form a positioning and clamping method, applicable to semi-trailer frames of different sizes.

[0016] 3. This application uses three clamping mechanisms to clamp the main beam of the semi-trailer frame, which can reduce the deformation of the semi-trailer frame during overturning, thereby improving the quality of the semi-trailer frame. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0023] Example: like Figure 1As shown in the illustration, this application discloses a clamping mechanism and a clamping device for semi-trailers, used to clamp a semi-trailer frame and flip it over after clamping. Compared with existing clamping methods, this application uses external clamping and positioning first, followed by internal auxiliary clamping, thus making it suitable for various sizes of products to be processed. Preferably, this application is applied in the field of semi-trailer processing, used to clamp the semi-trailer frame for easy subsequent flipping, welding, and completion of processing.

[0024] The specific structure of this application includes: Support base 1, which is an existing base component, is used to connect with other components. It can be a fixed connection or a detachable connection. The clamping drive mechanism 2 is mounted on the support base 1. The clamping drive mechanism 2 is an existing drive mechanism, which can be a lead screw drive mechanism or other drive mechanisms. Multiple clamping blocks 3 are installed on the movable end of the clamping drive mechanism 2, and the clamping blocks 3 move towards each other or away from each other under the drive of the clamping drive mechanism 2. The clamping side of the clamping block 3 is an inclined surface. This application clamps the main beam of the semi-trailer frame by the inclined surface, which can ensure the stability after clamping and avoid deformation of the corresponding area of ​​the semi-trailer frame.

[0025] In order to improve the stability after clamping, this application designs the clamping block 3. The specific number of the clamping block 3 is four, which are divided into two groups, namely the first group 4 and the second group 5. The first group 4 includes two clamping blocks 3 located on the outer side, and the inner side of each clamping block 3 is an inclined surface; The second group 5 includes two clamping blocks 3 located on the inner side, and the outer side of each clamping block 3 is an inclined surface; the inner side and the outer side here refer to the relative positions of the four clamping blocks 3, wherein the first group 4 is located on both sides of the second group 5 relative to the second group 5, and the clamping blocks 3 of the second group 5 are located between the two clamping blocks 3 of the first group 4. There are two clamping drive mechanisms 2 arranged side by side. One of the clamping drive mechanisms 2 drives the first group 4 to move, and the other clamping drive mechanism 2 drives the second group 5 to move. In this application, one clamping drive mechanism 2 drives a group of clamping blocks 3 to move, so as to complete the action of clamping on the outside first and then clamping on the inside.

[0026] Specifically, the clamping drive mechanism 2 described in this application has a support plate 6 mounted on its side. The support plate 6 is preferably located between the two clamping drive mechanisms 2 to support the workpiece to be processed, and at the same time facilitates the clamping block 3 to perform clamping on it.

[0027] In order to facilitate the stable movement of the clamping block 3 and prevent interference, the bottom of the clamping block 3 in this application is provided with a clamping groove 7 that cooperates with the support plate 6; in this way, the clamping block 3 can also move in a certain direction when moving towards each other.

[0028] To ensure the stability of this application during operation, this application also includes a mounting base 8, on which a groove 9 is provided to cooperate with the support base 1, so that the support base 1 can move along the groove 9 during subsequent assembly.

[0029] To ensure the stability of the support 1 during movement, the groove 9 described in this application is an inverted T-shape.

[0030] A push cylinder 10 is installed on the mounting base 8 described in this application. The piston rod end of the push cylinder 10 is connected to the clamping block 3. The position of the clamping drive mechanism 2 can be adjusted by using the push cylinder 10. Specifically, the movement direction of the piston rod of the push cylinder 10 is perpendicular to the movement direction of the clamping block 3.

[0031] like Figure 2 As shown, this application also discloses a clamping device for semi-trailers, comprising: Bracket 11; At least three of the aforementioned clamping mechanisms 12 are mounted on the bracket 11 and are used to clamp the main beam of the semi-trailer frame to achieve three-section clamping, thereby ensuring uniformity and avoiding deformation during the clamping and flipping process.

[0032] The working process for this application is as follows: The semi-trailer frame is transported to the clamping mechanism by a transport device. Then, one of the clamping drive mechanisms is activated, which drives the clamping blocks on the outside to move towards each other to complete the positioning and push the semi-trailer frame to move, completing the initial clamping. Then, the remaining clamping drive mechanism is activated, which drives the clamping blocks on the inside to move away from each other and clamp them at the main beam of the semi-trailer frame, thereby completing the clamping action and facilitating subsequent processing.
