Description

Technical Field

[0001] The utility model belongs to the technical field of expansion connection, and in particular relates to a hydraulic expansion gun with a vibrator and automatic expansion connection equipment. Background Art

[0002] During the hydraulic expansion process, due to the uneven ends of the pipes, it is necessary to first push the pipes to a uniform length before expanding. In other words, the pipe flattening operation is performed first, and then the hydraulic expansion is performed. To improve the efficiency of the pipe flattening operation, a vibrator is installed at the expansion gun. The vibration is transmitted through the expansion gun to the pipe, causing the pipe to vibrate relative to the tube sheet, thus facilitating the pipe flattening operation.

[0003] At present, in order to improve the fault tolerance of automatic tube expansion equipment, a floating device is often set outside the expansion gun. However, the superposition of the floating device and the vibrator makes the head volume too large, increases the axial length of the expansion gun, and then causes motion interference to the end of the robot arm, affecting the automatic expansion. Utility Model Content

[0004] The utility model provides a hydraulic expansion gun with a vibrator and automatic expansion equipment, which are used to solve the problem that the volume of a machine head is too large due to the superposition of a floating device and a vibrator.

[0005] The embodiments of the present invention are achieved through the following technical solutions:

[0006] A hydraulic expansion gun with a vibrator comprises an expansion gun body provided with a vibrator and a floating device, wherein the floating device comprises a first floating assembly and a second floating assembly arranged at intervals, and the vibrator is arranged between the first floating assembly and the second floating assembly.

[0007] This design cleverly utilizes the extra space in the first floating assembly and the second floating assembly to set the vibrator, avoiding the superposition of the floating device and the vibrator causing the head to be too large.

[0008] In some technical solutions of the present invention, the first floating assembly is provided at the front end of the expansion gun body, and the vibrator is provided at the front end of the expansion gun body.

[0009] The vibrator is arranged at the front end of the expansion gun body, which makes the gun head of the expansion gun body vibrate more effectively, thereby improving the vibration effect on the pipe.

[0010] In some technical solutions of the present invention, the first floating assembly includes a first outer ring member mounted on the expansion gun body, and a plurality of first buffer members are provided between the first outer ring member and the expansion gun body. The second floating assembly includes a second outer ring member mounted on the expansion gun body, and a plurality of second buffer members are provided between the second outer ring member and the expansion gun body.

[0011] In this design, the elastic deformation of the first and second buffer members is utilized to absorb the impact stress generated when the expansion gun bodies are skewed and docked.

[0012] In some technical solutions of the present utility model, the first buffer member and the second buffer member are both rubber rods.

[0013] Rubber has high elasticity and damping properties, which can effectively dissipate vibration energy and improve shock absorption effect.

[0014] In some technical solutions of the present invention, the number of the first buffer members is four and they are arranged at equal intervals, and the number of the second buffer members is four and they are arranged at equal intervals.

[0015] This design can more evenly buffer the impact stress generated by the expansion gun body.

[0016] In some technical solutions of the present invention, there are multiple vibrators, and the multiple vibrators are all arranged between the first floating component and the second floating component.

[0017] The number of vibrators can be adjusted as needed to increase the vibration effect.

[0018] In some technical solutions of the present invention, the front end of the expansion gun body is sleeved with an inner ring, the inner ring is arranged between the first floating assembly and the second floating assembly, and the vibrator is connected to the inner ring.

[0019] This design can ensure the connection strength of the vibrator to a certain extent and prevent the vibrator from moving during operation.

[0020] In some technical solutions of the present invention, there are two vibrators, which are arranged on two sides of the expansion gun body opposite to each other.

[0021] The vibrators are arranged symmetrically, which can make the head of the expansion gun body evenly weighted and make full use of the narrow space of the floating component, killing two birds with one stone.

[0022] An automatic expansion device comprises a hydraulic expansion gun with a vibrator.

[0023] Compared with the prior art, the embodiments of the present application have at least the following advantages or beneficial effects:

[0024] The hydraulic expansion gun with a vibrator and the automatic expansion joint equipment of the present application both cleverly utilize the redundant space in the floating device, thereby avoiding the overlapping of the floating device and the vibrator and the excessive size of the machine head.
