Description

Technical Field

[0001] This utility model relates to the field of centering mechanism technology, specifically a centering mechanism for a single-sided power buckle head. Background Technology

[0002] A pipe crimping machine, commonly known as a crimping machine or pipe clamping machine, is a hydraulic device used to crimp hydraulic oil pipe fittings assemblies. It uses a crimping machine mold and a hydraulic system to apply contraction force to the matching metal fittings, firmly crimping the metal fittings onto the matching hydraulic oil pipes and rubber hoses.

[0003] For example, the announcement number is CN216126447U (named "A New Type of Pipe Crimping Machine"), which includes a table. An operating table is fixedly connected to the upper surface of the table. A fixed base is threadedly connected to the upper surface of the table via bolts. The main body of the pipe crimping machine is fixedly connected to the upper surface of the fixed base. A base plate is fixedly connected to the upper surface of the table. Two vertical rods are fixedly connected to the upper surface of the base plate. A support block is provided above the base plate. Two smooth rods are fixedly connected to the lower surface of the support block. The vertical rods are slidably sleeved on the outside of their corresponding smooth rods. A round rod is fixedly connected to the lower surface of the support block. A support plate is fixedly connected between the two vertical rods. A first bevel gear is provided below the support plate. A screw is fixedly connected to the upper surface of the first bevel gear, and the screw penetrates the support plate. The screw is rotatably connected to the support plate via a bearing, and the screw is threadedly connected to the round rod. A first round hole is opened on the left side of the vertical rod on the right side. A crossbar is rotatably connected to the inner wall of the first round hole via a bearing. A second bevel gear is fixedly connected to the left end of the crossbar. The first bevel gear and the second bevel gear mesh with each other. A light is fixedly connected to the upper surface of the table. Through the cooperation between the screw, the first bevel gear, the second bevel gear, the round rod, the support block, and the crossbar, rotating the knob drives the crossbar to rotate. The crossbar drives the second bevel gear to rotate. The second bevel gear drives the first bevel gear to rotate. The first bevel gear drives the screw to rotate. The screw drives the round rod to move upward. The round rod drives the support block to move upward to the appropriate position. This solves the problem of traditional pipe clamping machines lacking a support device and requiring time and effort for handheld operation.

[0004] The aforementioned pipe crimping machine requires additional mechanisms to accommodate the positioning of materials during the crimping process, which makes operation inconvenient. To address this, we provide a centering mechanism for a single-sided power crimping head. Utility Model Content

[0005] The purpose of this utility model is to provide a centering mechanism for a single-sided power crimping head, so as to solve the problem mentioned in the background art that the existing crimping machine requires an additional mechanism to adapt to the positioning of the material during the crimping process, which makes the operation of the crimping machine inconvenient during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a centering mechanism for a single-sided power buckle head, including a support base, a positioning base above the support base, a movable base on one side of the positioning base, and four clamping claws on the inner walls of both the positioning base and the movable base.

[0007] Also includes:

[0008] The linkage block is fixed inside the movable base by screws. The four clamping claws and the linkage block are integrated into a linkage structure. A front frame plate is provided at the front end of the eight clamping claws. The front frame plate is integrated into the positioning base by screws.

[0009] A positioning base plate is welded to the front end face of the positioning base, and a cross-shaped connecting rod is provided on the front end face of the positioning base plate;

[0010] The guide slide rail is welded to the upper end of the support base, and the lower end of the movable base is welded with a bottom connecting slider.

[0011] Preferably, a central pivot is provided at the center of the cross link, and one support plate of the cross link is rotatably connected to the positioning seat plate through the central pivot.

[0012] Preferably, a front cover plate is provided at the front end of the front frame plate and the linkage pressure block. The front cover plate is in contact with the movable base and abuts against the top of one support plate of the cross linkage.

[0013] Preferably, a fastening bolt is provided at the connection position between the front cover plate and the movable base, and the front cover plate is fixedly connected to the movable base by the fastening bolt.

[0014] Preferably, one of the supports at the lower end of the cross-shaped linkage is fixedly connected to the base plate at the front end of the support base by screws.

[0015] Preferably, a central tube opening is provided at the center of the eight clamping claws, and four adjacent clamping claws are located on the same horizontal line.

[0016] Preferably, the movable base is movably connected to the guide rail on the support base via a bottom sliding block.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention uses a cross-linked connecting rod to abut against the front cover plate for limiting the position. The movable base is guided and connected to the guide rail on the support base through the bottom connecting slider, allowing the positioning base and the movable base to make symmetrical offset displacement as a whole, keeping the center position of the central pipe opening unchanged. Therefore, there is no need to use a positioning mechanism to fix the pipe fitting. This overcomes the problem that existing pipe crimping machines require additional mechanisms to adapt to the positioning of the material during the crimping process, which makes the operation of the pipe crimping machine inconvenient.
