Technical Field

[0001] This utility model relates to the field of axle machining, and in particular to a tooling for ensuring the machining accuracy of axles. Background Technology

[0002] As a key load-bearing and force-transmitting component in the vehicle chassis system, the machining accuracy of the axle directly affects the ride comfort, handling stability, tire wear, and service life of key components such as the main reducer.

[0003] Currently, some manufacturers design and manufacture dedicated fixtures for specific axle models. However, these dedicated fixtures are typically complex in structure, have long design and manufacturing cycles, are expensive, and can only be applied to a single product. Faced with market demands for flexible production of small batches and diverse product varieties, the limitations of these dedicated fixtures are very prominent, leading to difficulties in production line switchover and low equipment utilization. Utility Model Content

[0004] In view of this, the present invention aims to propose a tooling for ensuring the machining accuracy of vehicle axles, so as to solve the problems in the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: This utility model proposes a tooling for ensuring the machining accuracy of axles, including a base plate, a first side plate fixedly disposed on one side of the top surface of the base plate, a second side plate fixedly disposed on the other side of the top surface of the base plate, a mounting shell fixedly disposed on the side wall of the first side plate, an adjusting frame slidably disposed at an upper position at the end of the mounting shell, and a fixing plate fixedly disposed at a lower position at the end of the mounting shell. The adjusting frame is provided with a clamping rod, and the fixing plate is fixedly provided with a bottom rod corresponding to the clamping rod. The clamping rod has an upper inner groove, and the bottom rod has a lower inner groove. The upper inner groove and the lower inner groove are corresponding to each other. The end of the axle is located between the clamping rod and the bottom rod. The mounting shell has a mounting groove, and the mounting groove is provided with a driving component that drives the adjusting frame to slide up and down at the end of the mounting shell. The second side plate is provided with a clamping frame, which can enter the upper inner groove and the lower inner groove to abut against the end of the axle.

[0006] Furthermore, the drive assembly includes a rack whose end is fixedly connected to the bottom of the adjustment frame, the bottom end of the rack being slidably connected to the fixed plate, teeth on both sides of the gear, and a third gear and a fourth gear meshing on both sides of the gear, the third gear and the fourth gear being connected to a power assembly disposed in the mounting housing.

[0007] Furthermore, the power assembly includes a motor fixedly disposed within the mounting housing, a first gear fixedly connected to the output shaft of the motor, and a second gear meshing with the first gear. The second gear is rotatably connected to a connecting shaft, and the other end of the connecting shaft is fixedly connected to the inner sidewall of the mounting housing. The first gear and the third gear are fixedly connected, and the second gear and the fourth gear are fixedly connected.

[0008] Furthermore, a slot is provided on the top of the adjustment frame, and a rotating shaft is rotatably installed in the slot, through which the clamping rod is fixedly connected; A torsion spring is fitted onto the rotating shaft, with one end of the torsion spring fixedly connected to the rotating shaft and the other end fixedly connected to the adjustment frame.

[0009] Furthermore, the clamping frame has a sliding groove, and a limiting component is provided in the sliding groove. The limiting component includes a second screw and an abutment post. The second screw is symmetrically screwed to the upper and lower ends of the clamping frame, and the abutment post is slidably disposed in the sliding groove. The end of the second screw is rotatably connected to the sliding groove. When clamped, the upper and lower abutment posts abut against the top of the clamping rod and the bottom of the bottom rod, respectively.

[0010] Furthermore, the clamping frame is connected to the second side plate via a displacement assembly, which can drive the clamping frame into or out of the upper inner groove and the lower inner groove. The displacement assembly includes a first screw and a handrail. The first screw is screwed to the second side plate, and its end is rotatably connected to the clamping frame. The handrail is fixedly disposed at the other end of the first screw.

[0011] Furthermore, a blocking plate is fixedly provided at the end of the mounting shell away from the first side plate, and the blocking plate is located between the adjusting frame and the fixing plate.

[0012] Furthermore, the bottom rod is inclined on the fixed plate, with its end away from the fixed plate extending upward.

[0013] Compared with the prior art, this utility model has the following advantages: In this invention, the up-and-down sliding of the adjusting frame drives the clamping rod to move, which, together with the bottom rod on the fixing plate, enables precise positioning and clamping of the axle end from both the top and bottom directions. Simultaneously, the clamping frame can enter the upper and lower inner grooves to abut against the axle end, fixing the sidewall of the axle end and reducing the axle's shaking and displacement during processing.

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0020] The following will refer to the appendix. Figures 1 to 5 The present invention will be described in detail with reference to the embodiments.

[0021] Overall, this utility model relates to a tooling for ensuring the machining accuracy of axles, including a base plate 1, a first side plate 101 fixedly disposed on one side of the top surface of the base plate 1, a second side plate 102 fixedly disposed on the other side of the top surface of the base plate 1, a mounting shell 2 fixedly disposed on the side wall of the first side plate 101, an adjusting frame 4 slidably disposed at the upper end of the mounting shell 2, and a fixing plate 5 fixedly disposed at the lower end of the mounting shell 2. The adjusting frame 4 is provided with a clamping rod 404, and the fixing plate 5 is fixedly provided with a clamping rod 404 opposite to the clamping rod 404. The bottom rod 501 and clamping rod 404 are provided with an upper inner groove 405 and a lower inner groove 502, respectively. The upper inner groove 405 and the lower inner groove 502 are corresponding to each other. The end of the axle is located between the clamping rod 404 and the bottom rod 501. The mounting shell 2 is provided with a mounting groove 201. The mounting groove 201 is provided with a drive assembly that drives the adjusting frame 4 to slide up and down at the end of the mounting shell 2. The second side plate 102 is provided with a clamping frame 7, which can enter the upper inner groove 405 and the lower inner groove 502 and abut against the end of the axle.

[0022] In this embodiment, the up-and-down sliding of the adjusting frame 4 drives the clamping rod 404 to move, which, together with the bottom rod 501 on the fixing plate 5, enables precise positioning and clamping of the axle end from both the top and bottom directions. At the same time, the clamping frame 7 can enter the upper inner groove 405 and the lower inner groove 502 to abut against the axle end, fixing the side wall of the axle end and reducing the shaking and displacement of the axle during processing.

[0023] Since the adjusting frame 4 can slide up and down at the end of the mounting shell 2, the distance between the clamping rod 404 and the bottom rod 501 can be adjusted according to the size of different axle specifications through the drive component. This allows the tooling to be adapted to the processing of axles of various sizes, thus broadening the scope of tooling use, reducing the cost for enterprises to design tooling separately for different axle specifications, and improving the utilization rate of production resources.

[0024] In practice, the axle is placed between the base rod 501 and the clamping rod 404. The drive assembly in the mounting slot 201 is activated, and the adjusting frame 4 slides downward at the end of the mounting shell 2. As the adjusting frame 4 slides down, the clamping rod 404 also moves downward, gradually approaching the base rod 501, and the axle end is clamped between the clamping rod 404 and the base rod 501. After the clamping rod 404 and the base rod 501 initially clamp the axle end, the clamping frame 7 on the second side plate 102 moves towards the axle end until it enters the upper inner groove 405 of the clamping rod 404 and the lower inner groove 502 of the base rod 501, and tightly abuts against the axle end, further enhancing the clamping effect of the axle end. After the axle is firmly clamped, the processing equipment can be started to perform the required processing operations on the axle, such as drilling, milling, grinding, etc.

[0025] The aforementioned drive assembly includes a rack 306 whose end is fixedly connected to the bottom of the adjustment frame 4. The bottom end of the rack 306 is slidably connected to the fixed plate 5. Both sides of the gear are provided with teeth. A third gear 304 and a fourth gear 305 are respectively meshed on both sides of the gear. The third gear 304 and the fourth gear 305 are connected to the power assembly disposed in the mounting housing 2.

[0026] In practice, the power assembly inside the mounting housing 2 is activated, and the power assembly starts operating and outputs power, driving the third gear 304 and the fourth gear 305 to rotate. Since the third gear 304 and the fourth gear 305 mesh with the teeth on both sides of the gears respectively, the gears begin to rotate under the drive of the third gear 304 and the fourth gear 305. The rotation of the gears then causes the rack 306, which meshes with them, to move downwards. Because the end of the rack 306 is fixedly connected to the bottom of the adjusting frame 4, the adjusting frame 4 slides downwards at the end of the mounting housing 2 under the drive of the rack 306. As the adjusting frame 4 slides down, the clamping rod 404 also moves downwards, gradually approaching the bottom rod 501, and the end of the axle is clamped between the clamping rod 404 and the bottom rod 501.

[0027] The aforementioned power assembly includes a motor 3 fixedly installed inside the mounting housing 2, a first gear 301 fixedly connected to the output shaft of the motor 3, and a second gear 302 meshing with the first gear 301. The second gear 302 is rotatably connected to a connecting shaft 303, and the other end of the connecting shaft 303 is fixedly connected to the inner side wall of the mounting housing 2. The first gear 301 and the third gear 304 are fixedly connected, and the second gear 302 is fixedly connected to the fourth gear 305.

[0028] In practice, the motor 3 inside the mounting housing 2 is started, and the output shaft of the motor 3 begins to rotate, driving the first gear 301, which is fixedly connected to it, to rotate. Since the first gear 301 meshes with the second gear 302, the second gear 302 begins to rotate under the drive of the first gear 301. Furthermore, because the first gear 301 is fixedly connected to the third gear 304, and the second gear 302 is fixedly connected to the fourth gear 305, the third gear 304 and the fourth gear 305 also rotate along with the rotation of the first gear 301 and the second gear 302, respectively.

[0029] As a preferred structure in this embodiment, in order to facilitate the placement of the axle on the base rod 501, the top of the adjustment frame 4 is provided with a slot 403, and a rotating shaft 401 is rotatably provided in the slot 403. The clamping rod 404 is fixedly connected through the rotating shaft 401. A torsion spring 402 is fitted on the rotating shaft 401. One end of the torsion spring 402 is fixedly connected to the rotating shaft 401, and the other end is fixedly connected to the adjustment frame 4.

[0030] In actual operation, the clamping rod 404 is rotated to be perpendicular to the base rod 501, and the axle is placed on the base plate 1 from above. The clamping rod 404 is released, and the torsion spring 402 drives the clamping rod 404 to return to its original position, pre-clamping the placed axle.

[0031] In addition, when the clamping rod 404 encounters the end of the axle during descent, it can automatically rotate and clamp according to the size and shape of the axle, without requiring the operator to manually make complex angle adjustments to the clamping rod 404.

[0032] Based on the above configuration, the clamping frame 7 has a sliding groove 701, and a limiting component is provided in the sliding groove 701. The limiting component includes a second screw 702 and an abutment post 703. The second screw 702 is symmetrically screwed to the upper and lower ends of the clamping frame 7, and the abutment post 703 is slidably disposed in the sliding groove 701. The end of the second screw 702 is rotatably connected to the sliding groove 701. When clamping, the abutment posts 703 on the upper and lower sides abut against the top of the clamping rod 404 and the bottom of the bottom rod 501, respectively.

[0033] In practice, after moving the clamping frame 7 to the abutment position, rotate the second screws 702 at the upper and lower ends of the clamping frame 7 so that the abutment posts 703 on the upper and lower sides gradually approach the top of the clamping rod 404 and the bottom of the bottom rod 501 respectively. When the abutment posts 703 are in close contact with the top of the clamping rod 404 and the bottom of the bottom rod 501, stop rotating the second screws 702. At this time, the clamping frame 7, the clamping rod 404 and the bottom rod 501 together form a stable clamping structure.

[0034] Furthermore, the clamping frame 7 is connected to the second side plate 102 via a displacement assembly. The displacement assembly can drive the clamping frame 7 into or out of the upper inner groove 405 and the lower inner groove 502. The displacement assembly includes a first screw 6 and a handrail 601. The first screw 6 is screwed to the second side plate 102, and its end is rotatably connected to the clamping frame 7. The handrail 601 is fixedly installed at the other end of the first screw 6.

[0035] It should be noted that the rotating handle 601 drives the first screw 6 to rotate. Since the first screw 6 is screwed to the second side plate 102, and its end is rotatably connected to the clamping frame 7, the rotation of the first screw 6 will cause the clamping frame 7 to move towards the end of the axle.

[0036] It should be further explained that a baffle plate 8 is fixedly provided at the end of the mounting shell 2 away from the first side plate 101. The baffle plate 8 is located between the adjusting frame 4 and the fixed plate 5. The baffle plate 8 plays a protective role for the mounting shell 2. When the axle is placed on the bottom rod 501, it will impact the mounting shell 2, thus protecting its internal drive components.

[0037] Furthermore, the bottom rod 501 is inclined on the fixing plate 5, with its end away from the fixing plate 5 extending upward. This configuration facilitates the placement of the axle, and the inclined bottom rod 501 can better conform to its bottom shape.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
