Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub processing, in particular to a precision clamping tool for a mold used for wheel hub processing. Background Art

[0002] The car wheel hub bearing is an important component on the automobile chassis, and its manufacturing accuracy is directly related to the overall quality of the automobile. According to the different integration methods with other components of the automobile transmission system, it can be divided into the first, second, third and fourth generation wheel hub bearings. The wheel hub processing process can be uniformly processed by automatic production lines, which shortens the processing time and improves the processing efficiency. The disadvantage is that high-frequency quenching may cause slight deformation of some positioning surfaces during grinding, thereby affecting the accuracy of groove grinding and the position of bolt holes, which is not conducive to the stability of bearing unit operation. In the process of concentrated processing before heat treatment, most of them are rough turning processes. The equipment is a truss automatic line composed of a truss manipulator and two CNC lathes, a loading and unloading warehouse, a flip mechanism and a sampling unit, which can complete the rough and fine turning processes before heat treatment.

[0003] When the wheel hub mold is fixed, rough clamping is used, and the fixing precision and tightness are often not high, which will lead to reduced accuracy during the wheel hub production process. Utility Model Content

[0004] The utility model aims to provide a precision clamping tool for a mold used for hub processing, which has the effect of high-precision clamping and positioning.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a precision clamping tool for a wheel hub processing mold, comprising a bracket, a fixed platform arranged on the bracket, baffles fixedly arranged on adjacent two sides of the fixed platform, the two baffles are perpendicular to each other, and clamping members are respectively arranged on the other two sides of the fixed platform, the clamping members include two clamping plates, a control rod that drives the clamping plates and the baffles to approach each other, a steering block, a driving rod and a driving motor, the output end of the driving motor is connected to a bevel gear set, the driving rod is axially connected to the bevel gear set, the steering block is connected between the driving rod and the control rod, and the clamping plate is fixedly connected to the end of the control rod.

[0006] By adopting the above technical scheme, the utility model can realize the precise clamping and adjustment of the wheel hub mold. In the actual production process, the production of the wheel hub requires a high degree of precision. When the wheel hub mold is fixed, the fixing precision and tightness are often not high, which will lead to reduced accuracy in the production and processing of the wheel hub. Therefore, the utility model adopts precise clamping tooling to perform precise adjustment and clamping procedures on the wheel hub to improve its processing accuracy.

[0007] The utility model is further configured as follows: a driving bin is provided below the fixed platform, the bevel gear set is provided in the driving bin, the bevel gear set includes a driving bevel gear provided at the output end of the driving motor, two vertical bevel gears vertically meshed on the driving bevel gear, and a single bevel gear, and the single bevel gear is located between the two vertical bevel gears.

[0008] The utility model is further configured as follows: the ends of the driving rod are provided with external threads, the ends of the driving rod are threadedly connected to the driving sleeve, the side of the control rod close to the driving rod is provided with external threads, one end of the steering block is threadedly connected to the control rod, and the other end is movably engaged with the driving sleeve, and the driving rod is perpendicular to the control rod.

[0009] The utility model is further configured as follows: the spiral directions of the external threads at the two ends of the driving rod connected to the same single gear are opposite.

[0010] The utility model is further configured as follows: a limit rod is arranged at the end of the driving sleeve relative to the radial direction, a limit hole is arranged below the steering block, and the limit rod is movably clamped in the limit hole.

[0011] The utility model is further configured as follows: a guide rod is arranged on the fixing platform, and the clamping plate is slidably connected to the guide rod.

[0012] By adopting the above technical scheme, the driving motor drives the driving bevel gear to rotate in polarity, and the driving bevel gear drives the two vertical wheels and the single bevel gear to rotate. The single bevel gear does not mesh with the two vertical bevel gears, but only meshes with the driving bevel gear below. In the process of the two vertical bevel gears rotating, the driving rod will be driven to rotate. Since a limiting rod is provided at the end of the driving sleeve, the limiting rod is clamped in the limiting hole of the steering block. Therefore, the driving sleeve is threadedly connected to the driving rod. In the process of the driving rod rotating, the driving sleeve will move axially, thereby driving the rotating block to rotate. The rotating block is threadedly connected to the control rod, and the control rod is fixedly connected to the clamping plate, and a guide rod is provided between the clamping plate and the fixed platform. Therefore, the clamping plate is limited and cannot rotate, so the control rod cannot rotate either. When the rotating block is threadedly connected to the control rod and rotates, the control rod will move, and its movement direction is perpendicular to the driving rod, further driving the clamping plate to clamp and release.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model can realize the synchronous clamping process of multiple clamping plates, and can realize the precise clamping and adjustment of the wheel hub mold. In the actual production process, the production of the wheel hub requires a high degree of precision. When the wheel hub mold is fixed, the precision and tightness of the fixation are often not high, which will lead to reduced accuracy in the production and processing of the wheel hub. Therefore, the utility model adopts a precise clamping tool to perform a precise adjustment clamping process on the wheel hub to improve its processing accuracy.

[0015] 2. The driving motor drives the driving bevel gear to rotate in polarity, and the driving bevel gear drives the two vertical wheels and the single bevel gear to rotate. The single bevel gear does not mesh with the two vertical bevel gears, but only meshes with the driving bevel gear below. In the process of the two vertical bevel gears rotating, the driving rod will be driven to rotate. Since a limit rod is provided at the end of the driving sleeve, the limit rod is clamped in the limit hole of the steering block. Therefore, the driving sleeve is threadedly connected to the driving rod. In the process of rotation of the driving rod, the driving sleeve will move axially, thereby driving the rotating block to rotate. The rotating block is threadedly connected to the control rod, and the control rod is fixedly connected to the clamping plate, and a guide rod is provided between the clamping plate and the fixed platform. Therefore, the clamping plate is limited and cannot rotate, so the control rod cannot rotate either. When the rotating block is threadedly connected to the control rod and rotates, the control rod will move, and its movement direction is perpendicular to the driving rod, further driving the clamping plate to clamp and loosen.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Examples, such as Figure 1 , Figure 2 As shown, a precision clamping tool for a hub processing mold comprises a bracket 1, a fixed platform 2 arranged on the bracket 1, baffles 21 are fixedly arranged on adjacent two sides of the fixed platform 2, the two baffles 21 are perpendicular to each other, and clamping members 3 are respectively arranged on the other two sides of the fixed platform 2, the clamping members 3 comprise two clamping plates 31, a control rod 32 for driving the clamping plates 31 and the baffles 21 to approach each other, a steering block 33, a driving rod 34 and a driving motor 35, the output end of the driving motor 35 is connected to a bevel gear set, the driving rod 34 is axially connected to the bevel gear set, the steering block 33 is connected between the driving rod 34 and the control rod 32, and the clamping plate 31 is fixedly connected to the end of the control rod 32.

[0024] By adopting the above technical scheme, the utility model can realize the precise clamping and adjustment of the wheel hub mold. In the actual production process, the production of the wheel hub requires a high degree of precision. When the wheel hub mold is fixed, the fixing precision and tightness are often not high, which will lead to reduced accuracy in the production and processing of the wheel hub. Therefore, the utility model adopts precise clamping tooling to perform precise adjustment and clamping procedures on the wheel hub to improve its processing accuracy.

[0025] like Figure 2 , Figure 3 As shown, a driving bin 36 is provided below the fixed table 2, and the bevel gear set is provided in the driving bin 36. The bevel gear set includes a driving bevel gear 361 provided at the output end of the driving motor 35, two vertical bevel gears 362 vertically meshed on the driving bevel gear 361, and a single bevel gear 363, and the single bevel gear 363 is located between the two vertical bevel gears 362.

[0026] like Figure 4As shown, the ends of the driving rod 34 are provided with external threads 341, and the ends of the driving rod 34 are threadedly connected with the driving sleeve 342. The side of the control rod 32 close to the driving rod 34 is provided with an external thread 341. One end of the steering block 33 is threadedly connected to the control rod 32, and the other end is movably engaged with the driving sleeve 342. The driving rod 34 is perpendicular to the control rod 32.

[0027] like Figure 4 As shown, the spiral directions of the external threads 341 at both ends of the driving rod 34 connected to the same single gear are opposite.

[0028] like Figure 4 As shown, a limiting rod 3421 is radially arranged at the end of the driving sleeve 342 , a limiting hole 331 is arranged below the steering block 33 , and the limiting rod 3421 is movably engaged in the limiting hole 331 .

[0029] like Figure 4 As shown, a guide rod 22 is provided on the fixing platform 2 , and the clamping plate 31 is slidably connected to the guide rod 22 .

[0030] The driving motor 35 drives the driving bevel gear 361 to rotate polarity, and the driving bevel gear 361 drives the two vertical wheels and the single bevel gear 363 to rotate. The single bevel gear 363 does not mesh with the two vertical bevel gears 362, but only meshes with the driving bevel gear 361 below. During the rotation of the two vertical bevel gears 362, the driving rod 34 is driven to rotate. Since the end of the driving sleeve 342 is provided with a limiting rod 3421, the limiting rod 3421 is clamped in the limiting hole 331 of the steering block 33, the driving sleeve 342 is threadedly connected to the driving rod 34. Then, during the rotation of the driving rod 34, the driving sleeve 342 will move axially, thereby driving the rotating block to rotate. The rotating block is threadedly connected to the control rod 32, and the control rod 32 is fixedly connected to the clamping plate 31, and a guide rod 22 is provided between the clamping plate 31 and the fixed platform 2. Therefore, the clamping plate 31 is restricted from rotating, so the control rod 32 is also unable to rotate. When the rotating block is threadedly connected to the control rod 32 and rotates, the control rod 32 will move, and its movement direction is perpendicular to the driving rod 34, further driving the clamping plate 31 to clamp and loosen.

[0031] The utility model can realize the synchronous clamping process of multiple clamping plates 31, and can realize the precise clamping adjustment of the wheel hub mold. In the actual production process, the production of the wheel hub requires a high degree of precision. When the wheel hub mold is fixed, the fixing precision and tightness are often not high, which will lead to reduced accuracy in the production and processing of the wheel hub. Therefore, the utility model adopts precise clamping tooling to perform a precise adjustment clamping process on the wheel hub to improve its processing accuracy.
