Description

Technical Field

[0001] This utility model relates to the field of air conditioner parts manufacturing technology, and in particular to an adjustable clamp for welding air conditioner manifolds. Background Technology

[0002] The main function of the air conditioner manifold is to collect and distribute refrigerant, ensuring that the refrigerant flows evenly and efficiently within the system. The manifold ensures that the refrigerant is evenly distributed among the various parts of the heat exchanger, preventing some areas from being too cold or too hot, thereby improving heat exchange efficiency. The manifold is usually equipped with a regulating device, which can adjust the pressure and flow of the refrigerant according to the system requirements to ensure the stable operation of the system.

[0003] Air conditioning manifolds are mainly produced by welding. Multiple thinner branch pipes need to be welded and fixed to the surface of a thicker main pipe. Existing clamping tools fix the main pipe and then clamp the branch pipes at the top of the main pipe. In order to ensure that the bottom of the branch pipe is in effective contact with the surface of the main pipe and thus ensure the welding quality, the clamping height of each branch pipe needs to be adjusted. However, it is difficult to adjust the clamped branch pipes. Synchronous clamping equipment is not able to adjust the height of the clamped branch pipes individually. Utility Model Content

[0005] This utility model is achieved through the following technical solution:

The clamping mechanism is fixedly installed on one side of the top of the mounting frame, and the fixing mechanism is located on the outer side of the bottom of the clamping mechanism and fixed to the mounting frame. The clamping mechanism includes a first cylinder, a clamping seat, a mounting tube, an adjusting rod, a pressure plate, a pressure rod, a positioning pin, a movable clamping plate, a guide block, and a telescopic rod.

[0007] In a preferred embodiment of this utility model, the fixing mechanism includes a support base, a clamping base, a fixing block, a second cylinder, a movable block, and a screw. The support base is fixed to the mounting frame, the clamping base is clamped on the top of the support base, the fixing block is fixedly disposed on the inner side of one end of the clamping base, the second cylinder is fixed to the outer side of one end of the clamping base, the movable block is fixedly disposed on the telescopic end of the second cylinder, and the screw is fixedly disposed on the bottom of the clamping base.

[0008] The fixing mechanism is mainly used to effectively clamp the main pipe, while the adjustable clamping seat is used to ensure that the welding position is at the bottom of the branch pipe to be welded.

[0009] In a preferred embodiment of the present invention, the bottom end of the screw penetrates and extends to the outer side of the bottom of the support base, the bottom of the support base is provided with a waist-shaped hole that mates with the screw, and a locking nut is provided on the surface of the screw at the bottom of the support base;

[0011] In a preferred embodiment of the present invention, the movable clamp has a Y-shaped cross-section, and a pressure post is provided at one end of the movable clamp. The top of the pressure post at the end of the movable clamp is provided with a locking hole that cooperates with the positioning pin.

[0012] The branch pipe is clamped by a movable clamping plate. After clamping, the clamped branch pipe can be moved by applying pressure to the pressure column at the end of the movable clamping plate, thereby adjusting the contact between the bottom of the branch pipe and the surface of the main pipe to facilitate welding.

[0013] In a preferred embodiment of the present invention, the top of the clamping seat is provided with a limiting groove that cooperates with the guide block, and one end of the telescopic rod is connected to the bottom of the limiting groove at the top of the clamping seat.

[0024] like Figures 1-4 An adjustable clamp for welding air conditioning manifolds, as shown, includes a mounting frame 1, a clamping mechanism 2, and a fixing mechanism 3. The clamping mechanism 2 is fixedly mounted on one side of the top of the mounting frame 1. The fixing mechanism 3 is located on the outer side of the bottom of the clamping mechanism 2 and is fixed to the mounting frame 1. The clamping mechanism 2 includes a first cylinder 21, a clamping seat 22, a mounting tube 23, an adjusting rod 24, a pressure plate 25, a pressure rod 26, a positioning pin 27, a movable clamping plate 28, a guide block 29, and a telescopic rod 210. The clamping seat 2... 2 is fixedly installed at the telescopic end of the first cylinder 21, the mounting tube 23 is fixedly installed on the back of the clamping seat 22, the adjusting rod 24 is movably installed inside the mounting tube 23, the pressure plate 25 is movably connected to the adjusting rod 24, the pressure rod 26 is fixedly installed at the bottom of the pressure plate 25, the positioning pin 27 is fixedly connected to the bottom of the pressure rod 26, the movable clamping plate 28 is clamped on the inner side of the clamping seat 22, the guide block 29 is fixedly installed on the outer side of the movable clamping plate 28, and the telescopic end of the telescopic rod 210 is located at the bottom of the guide block 29.

[0025] Specifically, the fixing mechanism 3 includes a support base 31, a clamping base 32, a fixing block 33, a second cylinder 34, a movable block 35, and a screw 36. The support base 31 is fixed to the mounting frame 1. The clamping base 32 is clamped onto the top of the support base 31. The fixing block 33 is fixedly disposed on the inner side of one end of the clamping base 32. The second cylinder 34 is fixed to the outer side of one end of the clamping base 32. The movable block 35 is fixedly disposed on the telescopic end of the second cylinder 34. The screw 36 is fixedly disposed on the bottom of the clamping base 32. The bottom end of the screw 36 passes through and extends to the outer side of the bottom of the support base 31. 1. A waist-shaped hole is provided at the bottom to cooperate with the screw 36. A locking nut is provided on the surface of the screw 36 at the bottom of the support base 31. The movable clamping plate 28 has a Y-shaped cross-section. A pressure column is provided at one end of the movable clamping plate 28. A locking hole is provided at the top of the pressure column at the end of the movable clamping plate 28 to cooperate with the positioning pin 27. A limiting groove is provided at the top of the clamping base 22 to cooperate with the guide block 29. One end of the telescopic rod 210 is connected to the bottom of the limiting groove at the top of the clamping base 22. A thread is provided on the surface of the adjusting rod 24. A threaded hole is provided on the inner side of the mounting tube 23 to cooperate with it.

[0026] In this embodiment, after one end of the main pipe is secured to the outside of the fixed clamping block 33, the second cylinder 34 is driven to extend, thereby pushing the movable clamping block 35 at its telescopic end forward. The main pipe is clamped and fixed by the fixed clamping block 33 and the movable clamping block 35, ensuring that the main pipe is horizontally positioned and its welding area is vertically upward. Subsequently, the branch pipe is clamped. After the branch pipe is clamped in the corresponding position of the movable clamping plate 28, the first cylinder 21 is controlled to retract, driving the clamping seat 22 to move backward, thus achieving the initial clamping of the branch pipe. Since the height of the branch pipe is not uniform after clamping, the position of the branch pipe needs to be adjusted until its bottom is aligned with the main pipe. The welding positions on the pipe surface correspond to each other. At this time, it is necessary to rotate the adjusting rod 24 according to the clamping height of each branch pipe. The adjusting rod 24 is connected to the installation pipe 23 by threads. Rotating the adjusting rod 24 causes the pressure plate 25 connected to its surface to move down, controlling the pressure rod 26 to press down, applying pressure to the pressure column at the end of the movable clamping plate 28, causing the movable clamping plate 28 to move down, thereby driving the branch pipe to move down. The positioning pin 27 at the bottom of the pressure rod 26 is locked in the locking hole at the top of the pressure column to prevent the pressure plate 25 from rotating and to ensure the pressure effect. The guide block 29 effectively guides the movement of the movable clamping plate 28.

[0027] Furthermore, in some cases, due to the change in the diameter of the branch pipe and the main pipe, in order to ensure that the branch pipe is located in the middle of the main pipe, it is necessary to adjust the position of the main pipe. At this time, the locking nut on the surface of the screw 36 can be loosened to adjust the position of the clamping seat 32 back and forth. After the main pipe is adjusted to the appropriate position, the locking nut is tightened to lock the clamping seat 32. After welding is completed, the first cylinder 21 extends, causing the clamping seat 22 to push forward, thereby releasing the clamp from the branch pipe. At this time, the telescopic rod 210 installed at the bottom of the guide block 29 and located inside the clamping seat 22 resets, raising the movable clamping plate 28 to the rated position and resetting it.
