Description

Technical Field

[0001] This utility model relates to the field of clamps, specifically to a hydraulic clamp for maintaining an electric motor housing. Background Technology

[0002] After a period of use, motor housings may experience wear, cracking, and breakage of some components. Generally, these problematic motor housings are recycled for maintenance or repair. In existing technology, the motor housing is placed on a clamp consisting of plates or bolts. For example, the motor housing is placed on the clamp, and the plates hold it in place before repair. However, this type of clamp is not very secure. Furthermore, it requires manual operation, such as manually tightening the bolts to hold the motor housing in place. Moreover, due to limitations in the size and structure of the plates, this type of clamp can only hold motor housings of a specific size, limiting its applicability. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hydraulic clamp for motor housing maintenance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic clamp for maintaining a motor housing, comprising: a base and at least three clamping components; the base is provided with a fixing through hole, the fixing through hole penetrating the base; the three clamping components are evenly distributed circumferentially in the fixing through hole; at least a portion of the motor housing is inserted into the fixing through hole, thereby fixing the motor housing to the base; the clamping components are used to fix and clamp the motor housing, the clamping components include a first clamping component, a second clamping component, and a third clamping component; the third clamping component abuts against the motor housing from the bottom region; the first clamping component and the second clamping component fix and clamp the convex edge of the motor housing; the base, the first clamping component, the second clamping component, and the third clamping component cooperate to fix and clamp the motor housing.

[0005] Furthermore, the first clamping assembly includes a first hydraulic cylinder and a first clamping rod. The first hydraulic cylinder has a first telescopic rod. The first clamping rod and the first telescopic rod are fixedly installed together. The first hydraulic cylinder drives the first telescopic rod to rise and fall, and the first telescopic rod drives the first clamping rod to rise and fall.

[0006] Furthermore, the first clamping assembly also includes a pad, which is fixedly installed on the base by means of bolt connection, screw connection, snap-fit, welding, or adhesive bonding, and the first hydraulic cylinder is fixedly installed on the pad by means of bolt connection, screw connection, snap-fit, welding, or adhesive bonding.

[0007] Furthermore, the second clamping assembly includes a second hydraulic cylinder, which has a second telescopic rod. The second hydraulic cylinder drives the second telescopic rod to rise and fall. The second hydraulic cylinder is fixedly installed on the base by means of bolt connection, screw connection, snap-fit, welding, or adhesive.

[0008] Furthermore, the third clamping assembly includes a third hydraulic cylinder and a support plate. The third hydraulic cylinder has a third telescopic rod. The support plate and the third telescopic rod are fixedly installed together. The third hydraulic cylinder drives the third telescopic rod to rise and fall, thereby causing the third telescopic rod to drive the support plate to rise and fall.

[0009] Furthermore, the third hydraulic cylinder is fixedly installed on the base by means of bolt connection, screw connection, snap-fit, welding, or adhesive bonding.

[0010] Furthermore, the clamping assembly also includes a limiting member, and at least three of the limiting members of at least three clamping assemblies form a limiting space, within which the motor housing is placed; the limiting member is fixedly installed on the base by means of bolt connection, screw connection, snap-fit, welding, or adhesive.

[0011] Furthermore, the limiting member includes a connecting segment and a limiting member body, the connecting segment and the limiting member body are fixedly connected together, and at least three of the limiting members of at least three of the clamping components form the limiting space.

[0012] Furthermore, the protruding edge of the motor housing has an upper surface and a lower surface. The first clamping component presses the protruding edge from the upper surface of the protruding edge of the motor housing, and the second clamping component pushes the protruding edge from the lower surface of the protruding edge of the motor housing, thereby fixing and clamping the motor housing in place.

[0013] The beneficial effects of this application are: the hydraulic clamp for motor housing maintenance provided by this application has a simple structure, convenient and quick assembly and disassembly. Compared with the prior art, this application has at least the following three advantages: (1) At least three clamping components clamp the motor housing, each clamping component includes a first clamping component, a second clamping component, and a third clamping component. The first clamping component presses down on the motor housing, and the second and third clamping components push against the motor housing, so that the motor housing can be firmly clamped with a large clamping force; (2) The motor housing only needs to be placed on the base. The first clamping component, the second clamping component, and the third clamping component are all equipped with hydraulic cylinders. The hydraulic cylinders automatically clamp the motor housing, eliminating the need for manual clamping by workers, saving time and effort, and improving work efficiency; (3) Since the extension rod of the hydraulic cylinder in the first clamping component, the second clamping component, and the third clamping component is long enough, it can be applied to motor housings of different heights, with a wide range of applications.
