Description

Technical Field

[0001] This utility model relates to the field of clamping fixture technology, and in particular to a slant plate base clamping fixture. Background Technology

[0002] In existing technologies, the swashplate base, as a key component in continuously variable transmissions (CVTs), requires stringent precision in its machining. The swashplate base is a non-circular structure, necessitating rough milling, fine boring, and grinding of the inner hole on a three-axis lathe to meet drawing precision requirements. This process involves numerous steps, lengthy milling times, and the fact that only one swashplate base can be machined at a time. Furthermore, different machining processes often require repositioning and alignment, leading to reduced machining accuracy, low production efficiency, and significant time and labor costs.

[0003] Therefore, it is necessary to provide a slant plate base clamping fixture to overcome the defects mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a clamping fixture for a slant plate base.

[0005] According to one aspect of the present invention, a swashplate base clamping fixture is provided for fixing the swashplate base onto a lathe, comprising:

[0006] The clamp body includes a hollow cylindrical side wall and a mounting platform located inside the side wall for fixing the swashplate base;

[0007] The loading and unloading assembly includes a rotating shaft detachably mounted on the side wall, a handle mounted at one end of the rotating shaft, and a loading and unloading plate mounted at the other end of the rotating shaft for installing or removing the swashplate base. The handle is located on the outer side of the side wall, and the loading and unloading plate is located on the inner side of the side wall.

[0008] Preferably, the mounting platform has a clearance groove in the middle, and the clearance groove has a loading and unloading through hole that penetrates the side wall radially along the side wall.

[0009] Preferably, two mounting platforms are symmetrically provided inside the side wall for simultaneously mounting two inclined plate bases.

[0010] Preferably, the mounting platform is divided into a first mounting section and a second mounting section by a clearance groove. The first mounting section has a first threaded hole and a first pin hole, and the second mounting section has a second threaded hole and a second pin hole.

[0011] Preferably, the lines connecting the centers of the first threaded hole, the first pin hole, the second threaded hole, and the second pin hole in sequence form a rectangle, with the first threaded hole and the second threaded hole being diagonally distributed, and the first pin hole and the second pin hole being diagonally distributed.

[0012] Preferably, the center of the loading / unloading through hole is located at the intersection of the line connecting the centers of the first threaded hole and the second threaded hole and the line connecting the centers of the first pin hole and the second pin hole.

[0013] Preferably, the rotating shaft includes a first connecting section and a second connecting section, the diameter of the first connecting section is larger than the diameter of the second connecting section, a stepped surface is formed at the connection between the first connecting section and the second connecting section, the first connecting section is threadedly connected to the loading and unloading through hole, the second connecting section extends into the side wall, and a locking nut is provided on the second connecting section.

[0014] Preferably, a through hole is provided in the middle of the loading and unloading plate along the thickness direction, and the inner wall of the through hole is a smooth curved surface;

[0015] When installing the swashplate base, first insert the locating pin into the first and second pin holes, screw the shaft into the side wall, and then align the locating hole on the swashplate base with the locating pin. At this time, the second connecting section passes through the loading and unloading through hole and the clearance hole on the swashplate base that is coaxial with the loading and unloading through hole. Then, put the loading and unloading plate on the end of the second connecting section and abut against the swashplate base, and lock it in place with the lock nut. The loading and unloading plate is located between the swashplate base and the lock nut. By turning the handle, the first connecting section is rotated and moved outward, thereby driving the loading and unloading plate to apply pressure to the swashplate base, thereby pressing the locating pin into the locating hole until the swashplate base abuts against the mounting platform. Then, screw the fixing bolts into the first and second threaded holes respectively. Finally, remove the loading and unloading assembly.

[0016] Preferably, when disassembling the swashplate base, first unscrew the fixing bolts in the first and second threaded holes, then insert the loading / unloading plate into the clearance groove so that the through hole and the loading / unloading through hole are coaxial. At this time, screw the rotating shaft into the side wall, and the second connecting section passes through the loading / unloading through hole, the through hole and the clearance hole on the swashplate base in sequence. While the step surface is against the loading / unloading plate, continue to rotate the handle to drive the first connecting section to move inward. Then, the step surface applies pressure to the loading / unloading plate. After the loading / unloading plate pushes the swashplate base away from the positioning pin, the loading / unloading assembly is disassembled and removed.

[0017] Compared with the prior art, the inclined plate base clamping fixture provided by this utility model has the following advantages:

[0018] Due to the adoption of the above technical solution, this utility model has the advantages of simple structure, ingenious design and low cost. The swash plate base is positioned and installed on the fixture body through the loading and unloading components, and two swash plate bases can be installed in one fixture body, and the two swash plate bases can be processed in sequence. By clamping the fixture on the lathe, the swash plate base can be processed. One positioning can meet the processing requirements of multiple processes, without the need for repeated positioning and alignment, thereby improving production efficiency, reducing the parts transfer cycle and saving time and labor costs.

For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0037] See Figure 1 , Figure 2 and Figure 3 This embodiment discloses a clamping fixture for fixing the swash plate base 3 and clamping it on a lathe for subsequent processing of the swash plate base 3.

[0038] The swashplate base 3 clamping fixture includes a clamping body 1 and a loading / unloading assembly 2. The clamping body 1 includes a hollow cylindrical side wall 11 and a mounting platform 12 located within the side wall 11 for fixing the swashplate base 3. The mounting platform 12 protrudes inward from the inner surface of the side wall 11, and the surface of the mounting platform 12 is flat. Two symmetrically arranged mounting platforms 12 are provided within the side wall 11 for simultaneously fixing two swashplate bases 3. The inner surface of the side wall 11 between the two mounting platforms 12 is also provided with reinforcing ribs 15.

[0039] See Figure 4 and Figure 5 The mounting platform 12 has a clearance groove 13 in the middle, and a loading / unloading through hole 14 penetrating the side wall 11 is provided radially along the side wall 11 inside the clearance groove 13. The mounting platform 12 is divided into a first mounting part 121 and a second mounting part 122 by the clearance groove 13. The first mounting part 121 has a first threaded hole 1211 and a first pin hole 1212 perpendicular to the mounting plane. The second mounting part 122 has a second threaded hole 1221 and a second pin hole 1222 perpendicular to the mounting plane.

[0040] See Figure 6 The lines connecting the centers of the first threaded hole 1211, the first pin hole 1212, the second threaded hole 1221, and the second pin hole 1222 sequentially form a rectangle. The first threaded hole 1211 and the second threaded hole 1221 are diagonally distributed, as are the first pin hole 1212 and the second pin hole 1222. The center of the loading / unloading through hole 14 is located at the intersection of the line connecting the centers of the first threaded hole 1211 and the second threaded hole 1221 and the line connecting the centers of the first pin hole 1212 and the second pin hole 1222.

[0041] See Figure 7 The disassembly assembly includes a rotating shaft 21 detachably mounted on the side wall 11, a handle 22 located at one end of the rotating shaft 21, and a loading / unloading plate 23 located at the other end of the rotating shaft 21 for installing or removing the swashplate base 3. The handle 22 is located on the outer side of the side wall 11, and the loading / unloading plate 23 is located on the inner side of the side wall 11.

[0042] The rotating shaft 21 includes a first connecting section 211 and a second connecting section 212. The diameter of the first connecting section 211 is larger than the diameter of the second connecting section 212. A stepped surface 213 is formed at the connection between the first connecting section 211 and the second connecting section 212. The first connecting section 211 is threadedly connected to the loading and unloading through hole 14, and the second connecting section 212 extends into the side wall 11.

[0043] The loading and unloading plate 23 has a through hole 231 in the middle along the thickness direction, and the inner wall of the through hole 231 is a smooth curved surface.

[0044] See Figure 10The swashplate base 3 includes an arc-shaped opening 31 arranged front to back, a recessed groove 32 arranged left to right, and an upper contact surface 33 located at the top. The upper contact surface 33 has a through-hole 34, a positioning hole 35 corresponding to the pin hole, and bolt holes 36 corresponding to the first threaded hole 1211 and the second threaded hole 1221. The positioning hole 35 and bolt holes 36 are distributed around the periphery of the clearance hole 34.

[0045] See Figure 1 , Figure 8 and Figure 9 When installing the swashplate base 3, first insert the locating pin into the first pin hole 1212 and the second pin hole 1222, with both the locating pin and the first pin hole 1212 and the second pin hole 1222 being interference fits. Screw the rotating shaft 21 into the side wall 11, aligning the locating hole 35 on the swashplate base 3 with the locating pin for pre-positioning. At this time, the second connecting section 212 passes through the loading / unloading through hole 14 and the clearance hole 34 on the swashplate base 3, which is coaxially arranged with the loading / unloading through hole 14. The loading / unloading plate 23 is sleeved on the end of the second connecting section 212 and placed in the recessed groove 32 to abut against the swashplate base 3, and locked in place by the locking nut 24. The loading / unloading plate 23 is located between the swashplate base 3 and the locking nut 24.

[0046] By rotating the handle, the first connecting section 211 rotates and moves outward, thereby causing the loading and unloading plate 23 to apply pressure to the swashplate base 3, pressing the loading and unloading plate 23 towards the side where the mounting table 12 is located, and thus pressing the positioning pin into the positioning hole 35, until the upper contact surface 33 of the swashplate base 3 abuts against the mounting table 12. Then, the fixing bolts are screwed into the first threaded hole 1211 and the second threaded hole 1221 respectively to lock and fix the swashplate base 3. Finally, the disassembly assembly is removed. Both swashplate bases 3 can be installed on the swashplate base 3 clamping fixture, and then the fixture can be fixed on a lathe for turning of the swashplate base 3, improving production efficiency. At the same time, while meeting positioning and machining accuracy requirements, it reduces the parts transfer cycle and saves time and labor costs.

[0047] See Figure 2 When disassembling the swashplate base 3, first unscrew the fixing bolts in the first threaded hole 1211 and the second threaded hole 1221, then insert the loading / unloading plate 23 into the clearance groove 13, so that the through hole 231 is coaxial with the loading / unloading through hole 14. At this time, screw the rotating shaft 21 into the side wall 11, and the second connecting section 212 passes through the loading / unloading through hole 14, the through hole 231, and the clearance hole 34 in sequence. While the stepped surface 213 is abutting against the loading / unloading plate 23, continue to turn the handle to drive the first connecting section 211 to move inward, and then the stepped surface 213 applies pressure to the loading / unloading plate 23. After the loading / unloading plate 23 pushes the swashplate base 3 away from the positioning pin, remove the disassembly assembly to complete the disassembly work.

[0048] It will be apparent to those skilled in the art that various modifications and variations can be made to the exemplary embodiments of the present invention without departing from the spirit and scope of the present invention. Therefore, it is intended that the present invention cover modifications and variations falling within the scope of the appended claims and their equivalents.
