Taking the main clamp mechanism as an example, the main clamp mechanism includes a first crimping cylinder, a left main clamp and a right main clamp, and the left main clamp and the right main clamp are both provided with a first clamp rod extending upward and a first clamping portion extending downward, the cylinder body of the first crimping cylinder is hinged to the first clamp rod of the left main clamp, and the piston rod end of the first crimping cylinder is hinged to the first clamp rod of the right main clamp, and the first crimping cylinder is suspended at the top position of the left main clamp and the right main clamp, and the support force is mainly provided by the left main clamp and the right main clamp. During actual use of the crimping machine, due to the different weights of the cylinder body and the piston rod of the first crimping cylinder, the left main clamp and the right main clamp carry different loads and rotate at different angles. During actual use, the entire clamping mechanism will shake, resulting in concentricity deviation when the pipe is socketed, affecting the quality of the pipe socketing. Utility Model Content

DETAILED DESCRIPTION
[0020] The present application is further described in conjunction with the following embodiments. It should be noted that the directional terms appearing in the present application, such as "front", "rear", "left", "right", etc., are for the purpose of describing clearly with reference to the accompanying drawings and do not constitute a limitation on the scope of protection.
[0021] A specific implementation of a pipe socket machine with a synchronous centering bracket of the present application is as follows: Figure 1As shown, the socket-spiking machine includes a guide rail 1, and the guide rail 1 is provided with two articulated seats 2, one of which is fixedly mounted on the right end of the guide rail 1, and the other articulated seat 2 is slidably mounted in the guide rail 1. Specifically, a movable groove is provided on the inner side surface of the guide rail 1, and the end of the articulated seat 2 is inserted into the movable groove, so that the articulated seat 2 can slide relative to the guide rail 1. In order to improve the degree of automation, a mounting plate is fixedly mounted on the left end of the guide rail 1, and the mounting plate is provided with two push cylinders 11, and the two push cylinders 11 are arranged at intervals along the width direction of the guide rail 1, and the cylinder body of the push cylinder 11 is fixedly mounted on the mounting plate of the guide rail 1, and the end of the piston rod of the push cylinder 11 is fixedly connected to the slidable articulated seat 2. During the process of socket-spiking, the articulated seat 2 is driven by the push cylinder 11 to slide toward the other articulated seat 2.
[0022] In this embodiment, each articulated seat 2 is provided with an opening and closing oil cylinder 22 and two pairs of clamping jaws 21 hinged on the articulated seat 2. It should be noted that a hinge hole is provided in the middle of each clamping jaw 21, and the junction seat is provided with a rotating shaft extending toward the hinge hole, and each clamping jaw 21 is hinged on the articulated seat 2 through the rotating shaft.
[0023] The number of the clamping jaws 21 can be selectively set according to actual needs. In this embodiment, there are two pairs of the clamping jaws 21, and the two pairs of the clamping jaws 21 are arranged side by side or at intervals along the length direction of the guide rail 1. The function is to increase the contact area between the clamping jaws 21 and the pipe, thereby increasing the friction force and making the socket-jointing process smoother. Even for heavy pipes, the jaws will not fall off, ensuring the stability of the socket-jointing. The piston rod end and the cylinder end of the opening and closing oil cylinder 22 are fixedly connected with a connecting seat 24, and each connecting seat 24 is hinged to the top of the corresponding clamping jaw 21 through a rotating shaft 23. Specifically, the connecting seat 24 is formed with a pair of hinged ears facing outward, each of which is provided with a hinged hole, and the top end of each clamping jaw 21 is also provided with a hinged hole. A rotating shaft 23 passes through the hinged hole of the connecting seat 24 and the hinged hole of the clamping jaw 21 in sequence, so that the cylinder body of the opening and closing cylinder 22 is hinged to one of the clamping jaws 21, and the piston rod of the opening and closing cylinder 22 is hinged to the other clamping jaw 21. In addition, multiple pairs of clamping jaws 21 can be synchronously driven to move by one opening and closing cylinder 22, thereby saving the number of opening and closing cylinders 22 and reducing equipment costs.
[0024] Combination Figure 2 As an improvement, each articulated seat 2 is further provided with a centering bracket 3 fixedly mounted on the articulated seat 2, the centering bracket 3 is provided with a slide groove 31 arranged in the height direction, and a guide member 5 that can slide along the slide groove 31 is provided in the slide groove 31. In order to prevent the guide member 5 from rotating relative to the centering bracket 3, the cross-sectional shape of the slide groove 31 is rectangular. One end of the guide member 5 extends toward the slide groove 31 to form a rectangular portion 51 inserted into the slide groove 31, and the other end of the guide member 5 is hinged with a first connecting rod 41 and a second connecting rod 42.
[0025] In this embodiment, the end of the guide member 5 extends outward to form a first rotating shaft 52 hinged to the first connecting rod 41 and the second connecting rod 42, and the end of the first connecting rod 41 facing the guide member 5 and the end of the second connecting rod 42 facing the guide member 5 are both formed with a first shaft sleeve 43. In an optional solution, the first shaft sleeve 43 is a through hole formed at the end of the first connecting rod 41 or the end of the second connecting rod 42. In other embodiments, the shaft sleeve can also be welded to the end of the connecting rod and punched to allow the first rotating shaft 52 to pass through. In the assembled state, the first rotating shaft 52 is inserted into each first shaft sleeve 43, so that the first connecting rod 41 and the second connecting rod 42 can rotate relative to the guide member 5.
[0026] Optionally, the end of the first connecting rod 41 facing the opening and closing oil cylinder 22 and the end of the second connecting rod 42 facing the opening and closing oil cylinder 22 are both formed with a second sleeve 44. In the assembled state, each rotating shaft 23 is inserted into the corresponding second sleeve 44, so that the first connecting rod 41 and the piston rod of the opening and closing oil cylinder 22 and the second connecting rod 42 and the cylinder body of the opening and closing oil cylinder 22 can be hinged. In other embodiments, a through hole can also be directly opened at the end of the first connecting rod 41 or the end of the second connecting rod 42 to serve as the second sleeve 44.
[0027] In the pipe socket machine with synchronous centering bracket of this embodiment, during the opening and closing rotation of the claws, the two connecting rods act as two force arms to drag the corresponding claws. Since the sliding trajectory of the guide member 5 along the slide groove 31 is constant, the rotation trajectory of the two claws is limited, and the two claws are ensured to move synchronously, which solves the problem of shaking caused by uneven force on each clamping mechanism in the past, ensures the working stability of the socket machine, improves the accuracy and quality of pipe sockets, and thus improves production efficiency. The socket machine has a simple and compact structure, is suitable for crimping or socketing of various pipes, and has the characteristics of high precision and high working efficiency.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application, rather than to limit the scope of protection of the present application. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present application.
