Description

Technical Field

[0001] The present application relates to the field of pre-assembly tooling, and in particular, to a pre-assembly tooling for a steering pump joint. Background Art

[0002] The steering pump requires oil during its operation, and the steering pump is usually equipped with channels for oil inlet and oil return. Joints are required at the openings of these two channels. Generally, in actual applications, the steering pump is installed first and then the joints. However, due to problems with the setting of peripheral parts of some models, oil pipes may block the steering pump. The peripheral parts blocking the steering pump will make it difficult to tighten the joints and install them manually, thereby indirectly reducing the convenience of using the steering pump.

[0003] How to invent a tool that is convenient for pre-stabilizing and fixing the steering pump for joint installation has become an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0004] In order to remedy the above deficiencies, the present application provides a pre-assembly tooling for a steering pump connector, aiming to improve the problem that the existing steering pump lacks a tooling for quick assembly of the connector.

[0005] An embodiment of the present application provides a pre-assembled tooling for a steering pump joint, comprising a steering pump assembly and a tooling assembly.

[0006] The steering pump assembly includes a steering pump body, an oil inlet joint and an oil return joint, wherein the oil inlet joint and the oil return joint are respectively installed at the oil inlet and outlet interfaces of the steering pump body, wherein the tooling assembly includes a fixing plate and a mounting member, wherein the fixing plate is fixed to an external bearing platform, wherein the mounting member includes a cylindrical block, a connecting block and a bearing seat, wherein the cylindrical block is fixedly connected to the connecting block, wherein the connecting block is connected with a bolt I, and wherein the connecting block is movably fixed to the fixing plate by means of the bolt I, wherein the bearing seat is connected to the connecting block, wherein a threaded hole I is penetrated through the bearing seat, wherein the bolt II is installed on the bearing seat through the threaded hole I, and wherein the bearing seat is fixedly installed with the steering pump body by means of the cooperation between the bolt II and the threaded hole I.

[0007] In the above implementation process, first use bolt III to penetrate the corresponding U-shaped opening and the pre-opened threaded groove on the external bearing platform and tighten it to fix it, so as to facilitate the fixing of the fixing plate and the external bearing platform, and also facilitate the position fixing of the subsequent mounting parts. Then, use bolt I to penetrate the corresponding through hole on the connecting block and the threaded hole II opened on the fixing plate to fix it, so as to facilitate and quickly fix the connecting block to the fixing plate. The cylindrical block, the connecting block and the bearing seat are integrally formed and cast, and threaded holes I are also opened in pairs on both sides of the bearing seat, and bolts II are installed in the threaded holes I. When installing the oil inlet joint and the oil return joint, use bolt Ⅱ to penetrate the through hole on the steering pump body and the corresponding threaded hole Ⅰ on the bearing seat and tighten it. This makes it convenient to quickly fix the steering pump body. Finally, the oil inlet joint and the oil return joint are respectively fixed and tightened at the oil inlet and outlet interfaces of the steering pump body with the help of tools. This increases the convenience of installation of the oil inlet joint and the oil return joint, and has higher tightness and stability, and reduces the situation in subsequent actual applications where the oil inlet joint and the oil return joint are easily blocked by peripheral parts when assembled after the steering pump body, resulting in poor installation convenience.

[0008] In a specific implementation, the fixing plate is rectangular in shape as a whole, and pairs of U-shaped openings are provided on both ends of the fixing plate. The fixing plate is also provided with bolts III penetrating and connected to the U-shaped openings.

[0009] In the above implementation process, two bolts III can be selected for use. The two bolts III can be respectively passed through two staggered U-shaped openings and the pre-opened threaded grooves on the external load-bearing platform and tightened and fixed, so as to facilitate the subsequent rapid fixation of the steering pump body, and indirectly improve the convenience of installing the oil inlet joint and the oil return joint. When disassembling and replacing the fixing plate, only one of the bolts III needs to be loosened, which is convenient for disassembly.

[0010] In a specific implementation manner, the fixing plate is further provided with a threaded hole II adapted to the bolt I, and the connecting block is provided with a through hole adapted to the bolt I.

[0011] In the above implementation process, when it is necessary to fix the connecting block and the fixing plate, you can choose to use three bolts I to penetrate the corresponding through holes and threaded holes II at one time to tighten and fix them. This makes it convenient to detachably fix the connecting block and the fixing plate, reducing the subsequent overall replacement cost of the tooling.

[0012] In a specific implementation manner, the number of the threaded holes II and the number of the bolts I are both set to three, and the connecting lines between the three threaded holes II and the connecting lines between the three bolts I both form an equilateral right triangle.

[0013] In a specific implementation manner, four through holes are provided, and the connecting lines between the four through holes form a square.

[0014] In the above implementation process, the side length of the square formed by the above-mentioned connecting lines is equal to the right-angled side of the equilateral right triangle, so that the four through holes can be updated to align with the new threaded hole II, so that the bolt I can be fixed with the updated threaded hole II. This arrangement can change the installation position of the subsequent steering pump body according to the needs of the operator, adjust the installation angles of the oil inlet connector and the oil return connector to an angle suitable for the corresponding operator operation, and increase the convenience of the operator in installing the oil inlet connector and the oil return connector on the steering pump body.

[0015] In a specific embodiment, triangular diagonal support blocks are equidistantly connected to the side wall of the cylindrical block, and all the triangular diagonal support blocks are fixedly connected to the bottom of the connecting block.

[0016] In the above implementation process, the two side edges of the triangular diagonal support block are respectively formed integrally with the cylindrical block and the connecting block. The triangular diagonal support block can increase the structural strength of the cylindrical block and the connecting block, thereby indirectly improving the service life of the tooling.

[0017] In a specific implementation scheme, a circular through hole I is provided on the connecting block, and the aperture of the circular through hole I is the same as the aperture of the cylindrical block, a circular through hole II is provided on the bearing seat, the circular through hole II, the circular through hole I and the cylindrical block are coaxially arranged, the aperture of the circular through hole II is larger than the aperture of the circular through hole I, and one end of the steering pump body is clamped in the circular through hole II, the circular through hole I and the cylindrical block.

[0018] In the above implementation process, the circular through hole II and the circular through hole I as well as the cylindrical block are connected and coaxially arranged, so that the protruding end can be deeply plugged in when the steering pump body structure itself is installed, thereby increasing the convenience of installing the steering pump body and the bearing seat.

[0019] In a specific implementation scheme, the bearing seat is arranged in a shuttle shape as a whole, the number of the threaded holes I is set to four, the four threaded holes I are divided into two groups, the two groups of threaded holes I are respectively arranged at both ends of the bearing seat, and the two groups of threaded holes I are arranged parallel to each other.

[0020] In a specific embodiment, the number of the bolts II is set to two, and the two bolts II are respectively connected to the corresponding threaded holes I in an alternating manner.

[0021] In the above implementation process, when installing the steering pump body, two bolts II are used to penetrate the through holes on the steering pump body and the corresponding two staggered threaded holes I on the bearing seat and tighten them, so as to facilitate the steering pump body to be quickly fixed to the bearing seat. When the two threaded holes I are deformed and damaged due to long-term use, the two bolts II can also be used to tighten them with the other two threaded holes I to change the installation angle of the steering pump body, which can increase the service life of the bearing seat and indirectly improve the service life of the tooling.

[0022] In a specific implementation manner, the bearing seat is also provided with a pair of avoidance slots which are adapted to the bolts Ⅰ.

[0023] In the above implementation process, the avoidance slot is arranged in a C shape, and the arrangement of the avoidance slot can avoid the influence of the bearing seat on the installation and fixation of the bolt I. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] In the specific setting, the fixing plate 210 is rectangular as a whole, and U-shaped openings 230 are opened in pairs on both ends of the fixing plate 210. The fixing plate 210 is also provided with bolts III 240 that are connected to the U-shaped openings 230, wherein two bolts III 240 can be selected, and the two bolts III 240 can respectively pass through the two staggered U-shaped openings 230 and the pre-opened threaded grooves on the external bearing platform and be tightened and fixed, so as to facilitate the subsequent rapid fixation of the steering pump body 110, and indirectly improve the convenience of installing the oil inlet joint 120 and the oil return joint 130. When disassembling and replacing the fixing plate 210, only one of the bolts III 240 needs to be loosened, and the disassembly is convenient.

This makes it convenient to detachably fix the connecting block 222 and the fixing plate 210, thereby reducing the subsequent overall replacement cost of the tooling. The number of threaded holes II 250 and bolts I 224 is set to three, and the connecting lines between the three threaded holes II 250 and the connecting lines between the three bolts I 224 form an equilateral right triangle.

[0044] In the specific configuration, triangular diagonal bracing blocks are equidistantly connected to the side wall of the cylindrical block 221, and all triangular diagonal bracing blocks are fixedly connected to the bottom of the connecting block 222.

Among them, the circular through hole II, the circular through hole I and the cylindrical block 221 are connected and coaxially arranged, so that the protruding end of the steering pump body 110 can be deeply plugged in when the structure of the steering pump body 110 itself is installed, thereby increasing the convenience of installing the steering pump body 110 and the bearing seat 223.

[0045] In the specific setting, the bearing seat 223 is arranged in a shuttle shape as a whole, and the number of threaded holes I225 is set to four.

Casting, threaded holes I 225 are also opened in pairs on both sides of the bearing seat 223, and bolts II 226 are installed in the threaded holes I 225. When installing the oil inlet joint 120 and the oil return joint 130, the bolts II 226 are used to penetrate the through holes on the steering pump body 110 and tighten the corresponding threaded holes I 225 on the bearing seat 223, so that the steering pump body 110 can be quickly fixed. Finally, the oil inlet joint 120 and the oil return joint 130 are respectively fixed to the oil inlet and outlet interfaces of the steering pump body 110 with the help of tools, which increases the convenience of installing the oil inlet joint 120 and the oil return joint 130.

[0047] It should be noted that the specific model specifications of the steering pump body 110, the oil inlet connector 120 and the oil return connector 130 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
