[0038] Example

[0039] Reference Figure 1-3 In order to solve the problem in the prior art that the electric hydraulic pump may be mechanically damaged when the coupling is disassembled, the utility model proposes an electric hydraulic pump coupling disassembly device, including a long rod 1, a breaking block 2 arranged on the long rod 1, a connecting piece 3 connected to the long rod 1, and a clamping assembly 4 connected to the connecting piece 3.

[0040] Specifically, a top block 11 is provided at one end of the long rod 1, and a thread is provided at one end of the top block 11 at the other end of the long rod 1, that is, the long rod 1 is a cylindrical long bolt-like structure. A through hole is provided at the axis of the breaking block 2, and the diameter of the through hole is smaller than the cross-sectional diameter of the top block 11 to prevent the breaking block 2 from sliding off the long rod 1. After the long rod 1 passes through the through hole, the breaking block 2 can slide on the long rod 1, and the breaking block 2 is adapted to the top block 11, that is, after the breaking block 2 slides on the long rod 1, it collides with the top block 11, which can generate an impact force on the long rod 1 toward the top block 11. Preferably, the breaking block 2 is made of solid material to increase the weight of the breaking block 2, so that there is a greater impact force when the breaking block 2 hits the top block 11. The connecting member 3 is a square block-shaped structure. A first screw hole is provided at the center of the connecting member 3. One end of the long rod 1 provided with a thread is threadedly connected to the first screw hole, thereby fixing the long rod 1 to the connecting member 3. The clamping assembly 4 is provided on the side of the connecting member 3 away from the breaking block 2. The clamping assembly 4 is detachably connected to the connecting member 3 for easy maintenance and replacement. The clamping assembly 4 is provided with a clamping groove 41 away from the connecting member 3. The clamping groove 41 is an arc-shaped groove adapted to the outer surface of the coupling. The clamping groove 41 is sleeved on the outside of the coupling and tightly fits the surface of the coupling, thereby clamping and fixing the coupling.

[0041] In this embodiment, when the coupling needs to be separated from the hydraulic pump, the clamping assembly 4 and the part of the coupling exposed from the hydraulic pump are clamped and fixed, and then the breaking block 2 is pulled. When the breaking block 2 slides on the long rod 1, it hits the top block 11 fixedly connected to the long rod 1, generating an impact force toward the top block 11. This impact force is transmitted from the long rod 1 to the clamping assembly 4 through the connecting piece 3, so that the coupling is subjected to a pulling force in the opposite direction of the hydraulic pump, thereby pulling the coupling out of the hydraulic pump, solving the technical problem of mechanical damage when disassembling the coupling, and improving the technical effect of the overall performance of the electric hydraulic pump product.

[0042] In this embodiment, the clamping assembly 4 includes two clamping members 42. Specifically, the two clamping members 42 are detachably connected to the connector 3, and the two clamping members 42 are symmetrically arranged on the side of the connector 3 away from the breaking block 2 with the center of the connector 3 as the axis. That is, the two clamping members 42 are respectively located on both sides of the connector 3, forming a wrap around the coupling when clamping, thereby improving the clamping stability.

[0043] In this embodiment, two positioning holes 31 are symmetrically provided on the connecting member 3. The two positioning holes 31 are symmetrically arranged on the connecting member 3 with the center of the connecting member 3 as the axis to position the installation position of the clamping assembly 4. The two clamping members 42 are respectively provided with first thread grooves that are compatible with the two positioning holes 31, and a first screw 5 is provided in the thread groove. The tail of the first screw 5 passes through the positioning hole 31 and is then threadedly connected to the first thread groove, thereby connecting the clamping member 42 to the connecting member 3.

[0044] In some preferred embodiments, in order to further improve the stability of clamping the coupling, two second thread grooves are provided on the two clamping parts 42, and the two second thread grooves are symmetrically arranged with the center of the connecting part 3 as the axis. The two second thread grooves corresponding to the two clamping parts 42 are commonly threadedly connected with a second screw 6. The second screw 6 is threadedly connected to the second thread groove to connect the two clamping parts 42 and improve the clamping effect of the coupling.

[0045] In this embodiment, in order to facilitate the description of the clamping member 42, one clamping member 42 is used for illustration, and the clamping member 42 includes a column 421 and an abutment block 422. Specifically, the column 421 is provided on the side of the connecting member 3 away from the breaking block 2, and the column 421 is detachably connected to the connecting member 3. The abutment block 422 is provided on the side of the column 421 close to the center of the connecting member 3, the abutment block 422 and the connecting member 3 are vertically arranged, and the abutment block 422 is fixedly connected to the column 421. Among them, the clamping groove 41 is provided on the side of the abutment block 422 close to the center of the connected member 3, and the clamping groove 41 is located at the center of the abutment block 422, so that the clamping groove 41 can more accurately center and position the coupling.

[0046] Reference Figure 4 As shown, in some preferred embodiments, a limiting protrusion 4221 is further provided on the abutment block 422, and the limiting protrusion 4221 is located on the side of the clamping groove 41 away from the connecting member 3, and the limiting protrusion 4221 is fixedly connected to the abutment block 422, that is, when the abutment block 422 clamps the coupling, the limiting protrusion 4221 is located in the spline of the coupling, and the spline of the coupling is buckled, and the length of the limiting protrusion 4221 is greater than the shaft diameter of the coupling spline, so that the limiting protrusion 4221 can buckle the coupling spline.

[0047] In some preferred embodiments, the column 421 and the clamping block 422 are integrally formed, and the column 421 and the clamping block 422 are spliced ​​together to form a T-shaped structure, which can improve the overall strength of the part.

[0048] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
