Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a fixture for machining a balance wheel seat. Background Technology

[0002] The balance wheel seat is a key component in mechanical transmission or support. It is typically machined from cast or forged blanks and features a hollow structure with multiple areas to be machined. However, due to its unique structure, traditional fixtures present the following problems during the machining of balance wheel seats: First, traditional external surface clamping or end-face support methods are insufficient for achieving stable center positioning of the hollow balance wheel seat, easily leading to machining errors. Second, when machining multiple areas, it is usually necessary to disassemble the workpiece and re-clamp or adjust the fixture position, which is not only cumbersome and inefficient but also prone to errors due to repeated positioning, affecting machining consistency and product quality.

[0031] like Figures 1 to 3 As shown, in this embodiment, a jig for machining a balance wheel seat is used to fix a balance wheel seat 500. The balance wheel seat 500 includes a hollow wheel seat body 510, and the wheel seat body 510 is provided with a first machining part 520 and a second machining part 530. The jig includes:

[0032] Base 100;

[0033] The positioning component 200 includes a rotating shaft 210 rotatably mounted on the base 100 and extending in a horizontal direction, a wheel seat body 510 sleeved on the rotating shaft 210, and the rotating shaft 210 can drive the wheel seat body 510 to rotate along its own axis, and switch the first processing part 520 and the second processing part 530 in the processing position.

[0034] The clamping assembly 300 includes a first clamping structure 310 movably mounted on the base 100. The first clamping structure 310 has a first moving position and a second moving position. When the first clamping structure 310 moves to the first moving position, it abuts against the wheel seat body 510 and restricts the wheel seat body 510 from moving axially and rotating circumferentially. When the first clamping structure 310 moves to the second moving position, it separates from the wheel seat body 510 and releases the restriction on the wheel seat body 510. This design, through the cooperation of the rotatable shaft 210 and the first clamping structure 310, achieves accurate positioning and stable clamping of the balance wheel seat 500 on the one hand, and allows the first processing part 520 and the second processing part 530 to switch between processing positions as the wheel seat body 510 rotates. This effectively solves the problem that traditional fixtures are difficult to switch between multiple parts when processing the balance wheel seat 500, and significantly improves processing efficiency and clamping convenience.

[0035] In this embodiment, the jig for machining the balance wheel seat is mainly used to position and clamp the balance wheel seat 500 to meet its stable fixing requirements during milling and drilling processes. Figure 3 As shown, the balance wheel seat 500 includes a cylindrical hollow wheel seat body 510, the outer wall of which is provided with a first processing portion 520 and a second processing portion 530 extending in different directions, respectively used to cooperate with other components or to achieve specific functions. The first processing portion 520 extends axially along the wheel seat body 510 and is typically used for axial positioning or connection assembly; the second processing portion 530 extends radially along the wheel seat body 510 and is typically used for radial support or other structural cooperation.

[0036] like Figures 1 to 3 As shown, in this embodiment, the fixture includes a base 100, a positioning component 200, a clamping component 300, and a limiting structure 400.

[0037] Specifically, the base 100 serves as the fundamental support structure for the entire fixture, providing a stable mounting platform and ensuring the overall stability of the fixture during machining. Furthermore, the base 100 is rectangular and has multiple through-holes for detachable connections with the positioning assembly 200, the clamping assembly 300, and the limiting structure 400. This design not only improves the versatility and adaptability of the base 100 but also facilitates quick fixture replacement and maintenance.

[0038] In this embodiment, the positioning component 200 is used for basic positioning of the balance wheel seat 500 and serves as the core structure for switching the processing position of the balance wheel assembly. The positioning component 200 includes a rotating shaft 210, a positioning plate 220, and a first driving member (not shown in the figure). The rotating shaft 210 extends horizontally and is rotatably mounted on the base 100 via the positioning plate 220, forming a sleeve engagement with the wheel seat body 510 to drive the wheel seat body 510 to rotate around its own axis, thereby realizing the switching between the processing positions of the first processing section 520 and the second processing section 530.

[0039] Furthermore, the rotating shaft 210 is horizontally rotatably inserted into one side of the positioning plate 220 and connected to the output end of the first driving member, so as to realize the automatic rotation of the rotating shaft 210 under the drive of the driving member.

[0040] Furthermore, the rotating shaft 210 includes a first support portion 211 and a second support portion 212, which together form a circular boss structure. The diameter of the first support portion 211 is adapted to the inner diameter of the wheel seat body 510, used for accurate positioning of the wheel seat body 510 and driving its rotation. The diameter of the second support portion 212 is larger than that of the first support portion 211, abutting against the outer wall of the wheel seat body 510, used to cooperate with the first clamping structure 310 to fix both ends of the wheel seat body 510, ensuring the stability of the wheel seat body 510 during processing.

[0041] Preferably, the first support part 211 and the second support part 212 are integrally formed, which is beneficial to improving the structural strength and processing accuracy of the rotating shaft 210, and at the same time facilitates assembly and maintenance.

[0042] Furthermore, the positioning plate 220 has a rectangular plate structure and is vertically and detachably mounted on the base 100 to support the rotating shaft 210 and the first driving component. Preferably, the positioning plate 220 is connected to the mounting hole by fasteners, allowing the entire positioning assembly 200 to be installed or removed independently as a functional sub-module. This design not only facilitates assembly and debugging but also improves the versatility and maintainability of the fixture, and is beneficial for later replacement or adaptation to wheel seat bodies 510 of different specifications.

[0043] Furthermore, the first driving component is detachably mounted on the side of the positioning plate 220 opposite to the rotating shaft 210 via fasteners, and is connected to the second support portion 212 of the rotating shaft 210 to drive the rotating shaft 210 to rotate the wheel seat body 510. Preferably, the first driving component is a rotary motor, a cylinder, or a hydraulic cylinder.

[0044] In this embodiment, the clamping assembly 300 is used to cooperate with the positioning assembly 200 to clamp the balance wheel seat 500, ensuring its stability during processing. The clamping assembly 300 includes a first clamping structure 310, a second clamping structure 320, and a third clamping structure 330, as well as corresponding first mounting plates 340, second mounting plates 350, and third mounting plates 360. Each mounting plate is provided with a second driving member 341, a third driving member 351, and a fourth driving member 361, which are used to drive the corresponding clamping structure to move between a clamping position and a releasing position.

[0045] Furthermore, the first clamping structure 310 is movably mounted on the base 100 via the first mounting plate 340, and has a first moving position and a second moving position. When the first clamping structure 310 moves to the first moving position, it abuts against the end of the wheel seat body 510 away from the second support part 212, and can restrict the wheel seat body 510 from moving axially and rotating circumferentially, thereby achieving reliable fixation of the balance wheel seat 500 and ensuring its stability during processing. When the first clamping structure 310 moves to the second moving position, it separates from the wheel seat body 510 and releases the restriction on the wheel seat body 510, so that the first processing part 520 and the second processing part 530 can switch in the processing position, or realize the quick clamping and unloading operation of the wheel seat body 510.

[0046] Furthermore, the first clamping structure 310 is in the form of a circular boss, a rectangle, or a strip. Preferably, it is a circular boss, the diameter of which matches the diameter of the wheel seat body 510. This design allows the first clamping structure 310 to form a surface contact with the wheel seat body 510, thereby increasing the contact area, improving clamping stability, and avoiding workpiece deformation caused by local stress concentration, ensuring safety and reliability during the clamping process.

[0047] Furthermore, the first mounting plate 340 has a rectangular plate structure, is vertically and detachably mounted on the base 100, and is arranged opposite to the positioning plate 220, for supporting the first clamping structure 310 and the second driving member 341. The first clamping structure 310 is horizontally movably mounted on the first mounting plate 340 and is coaxial with the rotating shaft 210 to ensure that the clamping force is applied along the axial direction of the wheel seat body 510, further improving the symmetry and stability of the clamping. Preferably, the first mounting plate 340 is connected to the mounting hole by fasteners. This design not only facilitates assembly and debugging, but also improves the versatility and maintainability of the fixture.

[0048] Furthermore, the second driving member 341 is disposed on the side of the first mounting plate 340 opposite to the first clamping structure 310 and is connected to the first clamping structure 310, for driving it to move between the first moving position and the second moving position. Preferably, the second driving member 341 is one of a cylinder, a hydraulic cylinder or a motor, which can be flexibly selected according to processing requirements to realize automated control of the clamping action.

[0049] To prevent the centering position of the first processing unit 520 from shifting under external force during the initial clamping stage, a second clamping structure 320 is configured in this embodiment. The second clamping structure 320 is movably mounted on the base 100 via the second mounting plate 350 and has a third moving position and a fourth moving position. When the first processing unit 520 is in the processing position and the second clamping structure 320 moves to the third moving position, the second clamping structure 320 abuts against the second processing unit 530 and restricts the circumferential rotation of the wheel seat body 510, thereby achieving auxiliary positioning and anti-rotation clamping of the wheel seat body 510. When the second clamping structure 320 moves to the fourth moving position, the second clamping structure 320 separates from the second processing unit 530 and releases the restriction on the wheel seat body 510, so as to facilitate the position switching between processing units or the clamping and disassembly of the wheel seat body 510. This design, through the cooperation of the second clamping structure 320 and the second machining part 530, can provide auxiliary positioning and clamping for the wheel seat body 510 in the initial clamping stage, further improving the positioning accuracy and clamping stability of the balance wheel seat 500, and effectively avoiding machining deviations caused by clamping errors or external force disturbances.

[0050] Furthermore, the second clamping structure 320 is in the shape of a round block to improve the fit and clamping stability with the second processing part 530. Preferably, the second clamping structure 320 is detachably sleeved on the output end of the third drive member 351 for easy replacement and maintenance.

[0051] Furthermore, the second mounting plate 350 has a rectangular plate structure, is vertically and detachably mounted on the base 100, and is arranged perpendicularly to the positioning plate 220, for supporting the second clamping structure 320 and the third driving member 351. The second clamping structure 320 is horizontally movably mounted on the second mounting plate 350 and is arranged opposite to the second processing part 530 in the unprocessed position, ensuring that it can accurately abut against the second processing part 530 in the clamped state.

[0052] Furthermore, the third driving member 351 is disposed on the side of the second mounting plate 350 opposite to the second clamping structure 320 and is connected to the second clamping structure 320, for driving it to move between the third moving position and the fourth moving position. Preferably, the third driving member 351 is one of a cylinder, a hydraulic cylinder or a motor, which can be flexibly selected according to processing requirements to realize automated control of the clamping action.

[0053] To prevent the first processing unit 520 from vibrating due to cutting vibration or clamping force imbalance during the processing of the second processing unit 530, a third clamping structure 330 is also provided in this embodiment. The third clamping structure 330 is movably mounted on the base 100 via a third mounting plate 360 ​​and has a fifth moving position and a sixth moving position. When the second processing unit 530 is in the processing position and the third clamping structure 330 moves to the fifth moving position, the third clamping structure 330 abuts against the first processing unit 520 and can restrict the circumferential rotation of the wheel seat body 510. When the third clamping structure 330 moves to the sixth moving position, the third clamping structure 330 separates from the first processing unit 520 and releases the restriction on the wheel seat body 510, which facilitates the switching of subsequent processing units or unloading. This design, through the cooperation of the third clamping structure 330 and the first processing part 520, can work together with the first clamping structure 310 to achieve multi-point limiting of the balance wheel seat 500, further improving its positioning stability and clamping reliability, and effectively preventing processing errors caused by uneven clamping or vibration.

[0054] Furthermore, the third clamping structure 330 is in the shape of a round block to improve the fit and clamping stability with the first processing part 520. Preferably, the third clamping structure 330 is detachably sleeved on the output end of the fourth drive member 361 for easy replacement and maintenance.

[0055] Furthermore, the third mounting plate 360 ​​has a rectangular plate structure, is vertically and detachably mounted on the base 100, and is arranged perpendicularly to the positioning plate 220, for supporting the third clamping structure 330 and the fourth driving member 361. The third clamping structure 330 is horizontally movably mounted on the third mounting plate 360 ​​and is arranged opposite to the first processing part 520 in the unprocessed position, ensuring that it can accurately abut against the first processing part 520 in the clamped state.

[0056] Furthermore, the fourth driving member 361 is disposed on the side of the third mounting plate 360 ​​opposite to the third clamping structure 330 and is connected to the third clamping structure 330, for driving it to move between the fifth moving position and the sixth moving position. Preferably, the fourth driving member 361 is one of a cylinder, a hydraulic cylinder or a motor, which can be flexibly selected according to processing requirements to realize automated control of the clamping action.

[0057] To prevent machining errors caused by over-rotation, a limiting structure 400 is also provided in this embodiment. This limiting structure 400 is cylindrical and vertically and detachably mounted on the base 100 via fasteners, located within the rotation trajectory of the first machining section 520. When the second machining section 530 is in the machining position, the limiting structure 400 abuts against the bottom edge of the first machining section 520, restricting the wheel seat body 510 from continuing to rotate in the original direction, thus achieving rigid limiting of the rotation angle. This design effectively ensures the angle control accuracy of the wheel seat body 510 during rotation, preventing clamping errors and machining defects caused by rotation angle deviations, and improving the reliability and repeatability of the fixture.

[0058] In this embodiment, multiple sets of clamping components 300, positioning components 200, and limiting structures 400 are provided and are arranged equidistantly along the length of the base 100. This design can simultaneously meet the requirements for the synchronous clamping and processing of multiple balance wheel seats 500, significantly improving the production efficiency of the fixture and the utilization rate of the equipment.
