Description

Technical Field

[0001] This utility model relates to the field of turning technology, and in particular to a turning clamping device for a car axle. Background Technology

[0002] The car axle is a crucial transmission component in a vehicle, and its machining quality directly affects the vehicle's stability and driving safety. Currently, during machining processes such as turning, the car axle requires clamping and fixing at both ends. Because car axles are generally quite heavy, they are prone to vibration during high-speed rotational machining. This vibration inevitably affects the machining quality of the car axle, thus reducing its overall performance. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a turning clamping device for a car axle.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A turning clamping device for a car axle includes a machining table and a chuck and a top cone rotatably disposed on the machining table. A clamping assembly is slidably disposed between the chuck and the top cone. The clamping assembly includes a clamping plate rotatably disposed on both sides of the upper and lower sides and a top plate disposed on one side of the two clamping plates. A first abutment wheel and a second abutment wheel are respectively disposed on the clamping plate and the top plate, which abut against the outer periphery of the car axle in a triangular shape.

[0006] Preferably, the clamping plate is rotatably mounted on the side plate via a rotating shaft, the top plate is slidably mounted on the guide plate of the side plate, one end of the top plate is provided with an inclined cone plate, and the side plate is equipped with an inclined block that slides against the cone plate.

[0007] Preferably, the side plate is provided with a second lead screw and a guide rod that are parallel to each other and pass through the inclined plate. The rotation of the second lead screw drives the inclined plate to slide along the length of the guide rod and press against the cone plate.

[0008] Preferably, the top plate is provided with sliders on both sides, the guide plate is provided with a groove adapted to the slider, and the outer end of the groove is provided with a stop plate that abuts against the slider.

[0009] Preferably, the clamping assembly is fixed to the slide plate, the slide plate is slidably disposed on the processing table, and the processing table is provided with a lead screw that drives the slide plate to slide.

[0010] Preferably, a base is fixed on the processing table, a top rod is slidably provided in the base, the top cone is rotatably mounted on the top rod, and the top cone and the chuck are located on the same central axis.

[0011] Preferably, a hydraulic cylinder is fixed on the base, and the output shaft of the hydraulic cylinder is connected to the push rod.

[0012] The beneficial effects of this utility model are:

[0013] 1. The two ends of the car shaft to be processed are fixed by the chuck and the top cone, and a clamping assembly is set between the chuck and the top cone. By setting the clamping assembly with the clamping plate and the top plate, the outer circumference of the car shaft is fixed by the abutment rollers on the two clamping plates and the abutment rollers on the top plate forming a triangle, thereby clamping and fixing the car shaft at multiple points to improve the stability of the car shaft during the rotary machining process, avoid vibration caused by the rotary turning of the car shaft, and thus improve the machining quality and accuracy of the car shaft. At the same time, by setting the car shaft to be fixed at multiple points, the clamping force required to stabilize the car shaft is reduced, thereby avoiding damage to the surface of the car shaft due to excessive clamping force.

[0014] 2. An inclined plate is provided on the side plate to abut against the top plate. The inclined plate presses against and limits the top plate to ensure the stability and reliability of the top plate when it abuts against and clamps the car axle. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1-5 As shown, a turning clamping device for a car axle includes a machining table 1 and a chuck 11 and a top cone 12 rotatably disposed on the machining table 1. The chuck 11 can be a common three-jaw chuck, and the top cone 12 and the chuck 11 are disposed on the same central axis. The two ends of the car axle to be machined are fixed by the chuck 11 and the top cone 12, and the car axle can be rotated by driving the chuck 11 to rotate.

[0024] A base 122 is fixed on the processing table 1. A top rod 123 is slidably provided inside the base 122. The top cone 12 is rotatably mounted on the top rod 123. The top rod 123 can drive the top cone 12 to move closer to the chuck 11 to press and clamp the two ends of the car axle.

[0025] Specifically, a hydraulic cylinder 121 is fixed on the base 122, and the output shaft of the hydraulic cylinder 121 is connected to the push rod 123 so that the push rod 123 can be driven to slide within the base 122 by the hydraulic cylinder 121.

[0026] A clamping component 2 is slidably disposed between the chuck 11 and the top cone 12. The clamping component 2 can be disposed in the middle between the chuck 11 and the top cone 12. The installation position of the clamping component 2 can also be adjusted on the processing table 1.

[0027] The clamping assembly 2 is fixed on the slide plate 24, which is slidably disposed on the processing table 1. The slide plate 24 can slide between the chuck 11 and the top cone 12. The processing table 1 is provided with a lead screw 25 that drives the slide plate 24 to slide. The lead screw 25 is connected to the output end of the drive motor 26. The drive motor 26 drives the slide plate 24 and the clamping assembly 2 to slide through the lead screw 25.

[0028] The clamping assembly 2 includes clamping plates 21 that are rotatably arranged in opposite directions and a top plate 23 on one side of the two clamping plates 21. The clamping plates 21 are rotatably mounted on the side plate 22 via a rotating shaft 212, and a second hydraulic cylinder 213 is rotatably mounted on the side plate 22. The output end of the second hydraulic cylinder 213 is rotatably connected to the clamping plates 21, so as to drive the clamping plates 21 to rotate through the second hydraulic cylinder 213 and the rotating shaft 212.

[0029] The clamping plate 21 and the top plate 23 are respectively provided with abutment roller 211 and abutment roller 231 that abut against the outer circumference of the car axle in a triangular shape. The abutment roller 211 and the rotating shaft 212 are distributed at both ends of the clamping plate 21. That is, the outer circumference of the car axle is fixed by the two abutment rollers 211 and abutment roller 231 forming a triangular abutment, thereby clamping and fixing the car axle at multiple points, so as to improve the stability of the car axle during the rotary machining process, avoid vibration caused by the rotary turning of the car axle, and thus improve the machining quality and precision of the car axle.

[0030] Meanwhile, by using a multi-point clamping and fixing mechanism for the car axle, compared to the traditional front and rear clamping and fixing method, the clamping force required to stably clamp the car axle is reduced, thereby avoiding damage to the car axle surface due to excessive clamping force, and thus improving the processing effect of the car axle.

[0031] Furthermore, the top plate 23 is slidably disposed on the guide plate 221 of the side plate 22, and an inclined cone plate 233 is provided at one end of the top plate 23. The cone plate 233 and the abutment wheel 231 are distributed at both ends, and an inclined block 3 that slides against the cone plate 233 is installed on the side plate 22.

[0032] Specifically, the side plate 22 is provided with a lead screw 31 and a guide rod 33 that are parallel to each other and pass through the inclined block 3. A drive motor 32 is installed on the side plate 22. The output end of the drive motor 32 is connected to the lead screw 31 to drive the lead screw 31 to rotate. Then, the rotation of the lead screw 31 drives the inclined block 3 to slide along the length direction of the guide rod 33 and press against the cone plate 233. The inclined block 3 presses against the limiting top plate 23 to ensure the stability and reliability of the abutment wheel 231 on the top plate 23 when it abuts against the clamping axle.

[0033] The top plate 23 is provided with sliders 232 on both sides, and the guide plate 221 is provided with a groove 222 that matches the sliders 232. When the inclined block 3 presses the cone plate 233 of the top plate 23, the sliders 232 drive the top plate 23 to slide along the groove 222. The outer end of the groove 222 is provided with a stop plate 223 that abuts against the slider 232. The stop plate 223 abuts against the limiting slider 232 to prevent the top plate 23 from sliding away from the guide plate 221.

[0034] 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.
