Description

Technical Field

[0001] This utility model relates to steel pipe processing, specifically a special clamp for automatic pipe welding. Background Technology

[0002] Specialized clamps for automatic pipe welding are widely used in industrial production and construction due to their ease of operation by a single person and their stability. However, using these clamps requires careful setup. First, the clamp must be securely fixed to ensure accurate and stable pipe positioning during welding, guaranteeing weld precision and quality. After welding one side, the steel material usually needs to be removed and the clamp adjusted to weld the other side, making the process cumbersome and slowing down efficiency. Furthermore, most clamps use two-sided symmetrical clamping or three-point positioning methods for square and three-circular welding materials, lacking adaptability to various welding materials. Therefore, we propose a specialized clamp for automatic pipe welding. Utility Model Content

[0003] The purpose of this invention is to provide a special clamp for automatic pipe welding, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a special clamp for automatic pipe welding, comprising a base, a clamping mechanism, and a connecting mechanism, characterized in that: one end of the connecting mechanism is fixedly and symmetrically connected to both sides above the base, and the inner wall of the connecting mechanism is connected to the outer wall of the clamping mechanism through a first ball and a second ball;

[0005] The clamping mechanism has a first groove, a snap ring track, and a second groove sequentially formed on one side of its outer wall. The snap ring track is an inwardly concave arc groove, and two snap ring grooves are symmetrically formed within the snap ring track groove.

[0006] Preferably, the other end of the clamping mechanism has four symmetrically distributed grooves with threaded through-connection mechanisms, and the threads in the four grooves engage with the threads on the surfaces of the four clamping bolts.

[0007] Preferably, the connecting mechanism includes a positioning spring, which is disposed inside the ring of the connecting mechanism, with one end protruding from a groove opened in the inner wall of the connecting mechanism. The other end of the positioning spring is fixedly connected to the top of a spring on one side and the bottom of a spring switch on the other side, with the top of the spring switch protruding from a groove opened in the outer wall of the connecting mechanism.

[0008] Preferably, the inner wall of the connecting mechanism has a third groove and a fourth groove, and the third groove and the fourth groove are inner arc grooves. The third groove and the fourth groove are located on both sides of the groove in the inner wall of the positioning spring of the connecting mechanism.

[0009] Preferably, the first ball is disposed within the arc of the first groove and the third groove to form a rolling connection.

[0010] Preferably, the second ball is disposed within the arc of the second and fourth grooves to form a rolling connection.

[0011] Compared with the prior art, this utility model provides a special clamp for automatic pipe welding, which has the following advantages:

[0012] 1. This special fixture for automatic pipe welding is characterized by a clamping mechanism in which a positioning spring limits the clamping mechanism during use, thereby facilitating welding operations. After welding one side, pressing the spring switch releases the positioning spring, allowing rotation via a rolling connection between the clamping mechanism and the first and second ball bearings within the connecting mechanism, thus adjusting the welding position. This design reduces the complexity of removing the welding steel to adjust the fixture for welding the other side, thereby improving overall work efficiency.

[0013] 2. The special fixture for automatic welding pipe is characterized in that four symmetrically distributed grooves with threaded through-connection mechanisms are evenly opened at the other end of the clamping mechanism, and the threads in the four grooves engage with the threads on the surfaces of four clamping bolts, thereby forming a four-point positioning. It is suitable for square and round pipes. The four-point positioning can also better adapt to other irregularly shaped pipes, providing more flexible positioning. At the same time, the four-point positioning can more stably fix the pipe, ensuring the accuracy and stability of welding. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between 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.

[0024] This utility model provides the following technical solution:

[0025] Combination Figures 1 to 6 In this embodiment of the invention, one end of the symmetrically connected connecting mechanism 3 is fixed on both sides of the upper part of the base 1. The inner wall of the connecting mechanism 3 is connected to the outer wall of the clamping mechanism 2 by a first ball bearing 4 and a second ball bearing 5. A first groove 201, a snap ring track 202, and a second groove 204 are sequentially opened on one side of the outer wall of the clamping mechanism 2. The snap ring track 202 is a concave arc groove, and two snap ring grooves 203 are symmetrically opened in the groove of the snap ring track 202. Four symmetrically distributed grooves with threads penetrating the connecting mechanism 3 are evenly opened at the other end of the clamping mechanism 2, and the threads in the four grooves engage with the threads on the surface of four clamping bolts 205. This forms a four-point positioning system, which is suitable for square and round pipes. The four-point positioning system can also better adapt to other irregularly shaped pipes, providing more flexible positioning. At the same time, the four-point positioning system can more stably fix the pipe, thereby improving the overall work efficiency.

[0026] In an embodiment of this utility model, the connecting mechanism 3 includes a positioning spring 301. The positioning spring 301 is disposed inside the annulus of the connecting mechanism 3, with one end protruding from a groove in the inner wall of the connecting mechanism 3. The other end of the positioning spring 301 is fixedly connected to the top of a spring 305 on one side and to the bottom of a spring switch 304 on the other side. The top of the spring switch 304 protrudes from a groove in the outer wall of the connecting mechanism 3. Through the clamping mechanism 2, the positioning spring 301 can limit the clamping mechanism 2 during use, thereby facilitating welding operations. After welding one side, pressing the spring switch 304 releases the positioning spring 301, allowing rotation through the rolling connection formed between the clamping mechanism 2 and the first ball 4 and the second ball 5 within the connecting mechanism 3, thus adjusting the welding position. This design helps ensure the accuracy and stability of the welding operation.

[0027] In an embodiment of this utility model, a third groove 302 and a fourth groove 303 are formed on the inner wall of the connecting mechanism 3, and the third groove 302 and the fourth groove 303 are inner arc grooves. The third groove 302 and the fourth groove 303 are located on both sides of the groove formed on the inner wall of the positioning spring 301 of the connecting mechanism 3. The first ball 4 is set in the arc of the first groove 201 and the third groove 302 to form a rolling connection, and the second ball 5 is set in the arc of the second groove 204 and the fourth groove 303 to form a rolling connection. By adopting a two-roller connection design, the stability of the overall structure can be significantly enhanced, so that it remains intact when subjected to the pressure of heavy steel, effectively avoiding the risk of structural damage.

[0028] Working principle: This embodiment provides a special clamp for automatic pipe welding. In use, the welding material is placed into the clamp through both ends and positioned by rotating multiple clamping bolts 205 at both ends. After welding one side of the welding material, the snap ring switch 304 is pressed, and the positioning snap ring 301 is released from its locking position with the snap ring groove 203, thus rotating the clamping mechanism 2 and causing the welding material to rotate. The positioning snap ring 301 rotates half a turn from the snap ring track 202 to the other snap ring groove 203, where it locks again to perform welding on the other side. After welding is completed, the clamping bolts 205 are released, the welding material is removed, and the welding is completed.
