Description

Technical Field

[0001] The utility model belongs to the technical field of gear shaft production, in particular to a punching machine for gear shaft processing. Background Art

[0002] A gear shaft is a mechanical component that supports a rotating part and rotates with it to transmit motion, torque, or bending moment. It is typically a round metal rod, with segments of varying diameters and externally mounted transmission gears. During production, gear shafts often require drilling holes on the outer surface or ends to accommodate various mounting and transmission options. However, due to the inherently hard material and unusual shape of gear shafts, drilling can easily cause slippage and vibration, affecting precision. This has led to the development of specialized drilling machines.

[0003] For example, patent application number CN202022568809.8 discloses a half-gear shaft punching machine, comprising a controller and a frame, the controller being arranged above the distribution box on the side of the frame, an operating platform being fixed on the top of the frame, a mounting plate being provided on the operating platform, a fixture assembly for fixing the half-gear shaft being fixed on the mounting plate, a punching mechanism being provided at one end of the operating platform, a back plate being fixed on one side of the operating platform, the mounting plate being slidably connected to the operating platform and the back plate, a driving mechanism being provided on the back plate for feeding the mounting plate toward the punching mechanism, the punching mechanism and the driving mechanism being electrically connected to the controller, the half-gear shaft comprising a rod having a semicircular cross-section, two positioning platforms having a semicircular structure at both ends of the rod, and a tooth structure being provided in the middle of the rod. The utility model can ensure that the half-gear shaft is well fixed during punching, and the punching feed is stable, the half-gear shaft will not loosen or shift, causing the drill bit to break or the hole to deviate, and is suitable for the technical field of hexagonal mesh processing equipment.

[0004] In the existing technology, the structure that cooperates with the external teeth of the gear shaft makes the half gear shaft loose and slip during drilling, thereby improving the drilling quality. However, there are still many deficiencies in overall use: first, the reinforcement of the gear shaft in the existing technology is mostly rigid fixation, and the vibration generated during drilling cannot be released in time, which easily leads to damage to the tool; second, the existing reinforcement structure cannot adapt to more complex gear shaft processing. When the gear shaft parameters change, it needs to be disassembled and replaced, which has low production efficiency and insufficient practicality. Utility Model Content

The utility model is provided with a pressure block and a hard block as well as an abutting roller and an air jet mesh, so that when the equipment processes the outer cylindrical surface of the gear shaft, it can form an adaptive clamping surface deformation outside the hole position, so that the support and fixing effect is guaranteed while absorbing the vibration generated by drilling, effectively improving the stability of the gear shaft and ensuring the processing quality.

[0008] Preferably, an elastic connecting plate is provided in the pressure block on one side of the guide arc surface, and a plurality of convex strips are provided on the outer circumferential surface of the abutting roller on one side of the elastic connecting plate.

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Example 1:

[0024] refer to Figure 1-7A punching machine for processing a gear shaft includes a base 31 and a driving seat 36. A driving seat 36 is provided on one side of the upper end surface of the base 31, and an abutment disk 39 is rotatably provided on the end surface of the driving seat 36. A second driving frame 33 is slidably provided on one side of the driving seat 36, and a three-jaw chuck 34 is rotatably provided on the end surface of the second driving frame 33. A first driving frame 32 is slidably provided between the second driving frame 33 and the driving seat 36, and a puncher 37 is slidably provided below the first driving frame 32. Two pressure blocks 38 are symmetrically slidably provided on both sides of the puncher 37. The two pressure blocks 38 are hollow inside and have an arc-shaped bottom. Abutment rollers 42 are provided on both sides of the bottom of the pressure block 38, and a hard block 41 is provided between the two abutment rollers 42 at the bottom of the pressure block 38. A support rod 40 is connected between the hard block 41 and the inner end surface of the pressure block 38, and guide arc surfaces 43 are provided on both sides of the pressure block 38.

[0025] Specifically, a driving motor is provided inside the driving seat 36, and the output end of the driving motor is connected to the abutment disk 39. The three-jaw chuck 34 is a prior art and will not be elaborated in detail in this solution. When the outer cylindrical surface of the gear shaft needs to be drilled, the staff can clamp and fix one end of the outer side of the gear shaft through the three-jaw chuck 34, and then push the second driving frame 33 so that the three-jaw chuck 34 can drive the other end of the gear shaft to abut against the end surface of the abutment disk 39, thereby completing the fixing of the gear shaft. The outer end surface of the abutment disk 39 is roughened. When the gear shaft is fixed, the driving motor inside the driving seat 36 can drive the abutment disk 39 to rotate, thereby driving the gear shaft abutting against the outside of the abutment disk 39 to rotate, thereby adjusting the angle and direction of the gear shaft drilling. In this relationship, the three-jaw chuck 34 rotates in coordination with the second driving frame 33 and can be driven to rotate by the gear shaft.

[0026] When the gear shaft is fixed, the first driving frame 32 can be moved to the punching position, and then the puncher 37 in the first driving frame 32 can be moved downward to complete the punching process of the gear shaft. In the process of the puncher 37 punching, the pressure blocks 38 on both sides of the puncher 37 will also move downward synchronously. The pressure blocks 38 are made of elastic rubber material as a whole and have the effect of absorbing vibration. The interior of the pressure block 38 is hollowed out, and the guide arc surfaces 43 on both sides are set in an arc shape, so that when the pressure block 38 is pressed on the outside of the gear shaft, it can bend and deform toward the guide arc surfaces 43 on both sides. The bottom of the pressure block 38 is also curved, so that the pressure block 38 can better fit on the outer circumferential surface of the gear shaft, and the abutting rollers 42 on both sides of the bottom of the pressure block 38 are protruding as a whole and the arc surface of the bottom of the pressure block 38 can form clamping and pressing points on both sides of the outer circumferential surface of the gear shaft, so that when the equipment is drilling, it can form fixed clamping points on both sides of the hole position and can absorb the vibration generated by drilling, thereby improving the overall drilling accuracy.

[0027] The hard block 41 is supported by the support rod 40. Both the hard block 41 and the support rod 40 are made of hard metal material. The bottom of the hard block 41 extends out of the arc surface of the pressure block 38, and the protruding end surface is roughened. When the bottom of the pressure block 38 is pressed on the outer cylindrical surface of the gear shaft, it can provide a hard support point, thereby improving the fixing effect of the gear shaft, avoiding shaking of the gear shaft during drilling, and improving accuracy.

[0028] refer to Figure 5 The outer surface of the guide arc surface 43 is provided with a plurality of deformation teeth 44 .

[0029] Specifically, the arrangement of the deformed tooth patterns 44 enables the guide arc surface 43 to bend smoothly under the action of the multiple deformed tooth patterns 44 when the bottom of the pressing block 38 is under pressure, thereby improving the shock absorption effect.

[0030] refer to Figure 7 A plurality of air-jet meshes 48 are provided on the end surface of the pressing block 38 close to the punch 37 , and an air inlet 47 is provided on the other end surface of the pressing block 38 .

[0031] Specifically, the outside of the air inlet 47 can be connected to a high-pressure gas source. When the pressure block 38 forms a support point outside the gear shaft, the staff can inject high-pressure gas into the pressure block 38, and then spray the gas onto the outside of the punch 37 and the hole position through the multiple jet mesh holes 48 on the end face of one side of the pressure block 38, thereby achieving the purpose of chip removal and improving the drilling quality.

[0032] refer to Figure 1 A first pushing cylinder 49 is provided in the middle of the end surface of the first driving frame 32, and the output end of the first pushing cylinder 49 is interconnected with the puncher 37. Second pushing cylinders 50 are provided on both sides of the first pushing cylinder 49, and the output end of the second pushing cylinder 50 is interconnected with the pressure block 38.

[0033] Specifically, the first push cylinder 49 and the second push cylinder 50 are both existing technologies, and this solution will not elaborate on them in detail. The output end of the first push cylinder 49 can push the puncher 37 to move up and down, thereby completing the drilling process, and the output end of the second push cylinder 50 can push the pressure block 38 to move up and down, thereby completing the reinforcement process of the gear shaft.

[0034] refer to Figure 1 The outer end surface of the three-jaw chuck 34 is provided with a plurality of clamping jaws 35 that slide evenly along the circumferential direction.

[0035] Specifically, the clamping surfaces of the multiple clamping claws 35 are all in a fan-shaped arc shape, which can effectively improve the clamping effect on the gear shaft and ensure the processing quality.

[0036] Furthermore, a first linear drive is provided on both sides of the upper end surface of the base 31, and the output end of the first linear drive is interconnected with the first drive frame 32. A second linear drive is provided between the two first linear drives, and the output end of the second linear drive is interconnected with the second drive frame 33.

[0037] Specifically, the first linear drive and the second linear drive are both existing technologies, and this solution will not elaborate on them in detail. The first linear drive can drive the first drive frame 32 to move back and forth above the gear shaft, and the second linear drive can drive the second drive frame 33 to move, thereby completing the clamping and rotation processing of the gear shaft. Example 2:

[0038] On the basis of or different from the first embodiment, reference is made to Figure 5 An elastic connecting plate 45 is provided in the pressing block 38 on one side of the guide arc surface 43 , and a plurality of convex strips 46 are provided on the outer circumferential surface of the abutting roller 42 on one side of the elastic connecting plate 45 .

[0039] Specifically, the provision of the convex strips 46 improves the surface roughness of the outer portion of the abutment roller 42, thereby effectively preventing the abutment roller 42 from slipping when forming a clamping point on the outer cylindrical surface of the gear shaft. The elastic connecting plate 45 is made of elastic material and is bent at multiple angles as a whole. It is supported and connected between the inner arc surface of the guide arc surface 43 and the bottom of the pressure block 38, and can elastically support the guide arc surface 43 and the bottom of the pressure block 38, thereby improving their deformation strength and thereby improving the reinforcement effect.
