Description

Technical Field

[0001] This utility model belongs to the field of gear shaft manufacturing technology, and in particular relates to a drilling machine for gear shaft processing. Background Technology

[0002] A gear shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. It is generally a metal rod, with different diameters in different sections, and is equipped with gears for transmission. During the production of gear shafts, drilling is often required on the outer surface or end to enable various installation and transmission methods. However, due to the hardness of the gear shaft material and its unique shape, slippage and wobbling can easily occur during drilling, affecting accuracy. Therefore, specialized drilling machines have been developed.

[0003] Patent application CN202022568809.8 discloses a half-gear shaft drilling machine, including a controller and a frame. The controller is located above a distribution box on the side of the frame. An operating platform is fixed on the top of the frame, and a mounting plate is provided on the operating platform. A clamping assembly for fixing the half-gear shaft is fixed on the mounting plate. A drilling mechanism is provided at one end of the operating platform, and a back plate is fixed on one side of the operating platform. The mounting plate is slidably connected to the operating platform and the back plate. A drive mechanism is provided on the back plate for feeding the mounting plate toward the drilling mechanism. The drilling mechanism and the drive mechanism are electrically connected to the controller. The half-gear shaft includes a rod with a semi-circular cross-section. The two ends of the rod have two semi-circular positioning platforms, and the middle of the rod has a toothed structure. This invention can ensure that the half-gear shaft is well fixed during drilling and that the drilling feed is stable. The half-gear shaft will not loosen or shift, which could lead to drill bit breakage or misalignment of the hole. It is applicable to the field of hexagonal mesh processing equipment technology.

[0004] In the existing technology, the structure that interacts with the external teeth of the gear shaft makes the half gear shaft loose and slip during drilling, which improves the drilling quality. However, there are still many shortcomings in its use: the gear shaft is usually long in order to complete the transmission of long distances and multiple stations. Therefore, when drilling is performed on one end, only the other end is fixed, which is prone to large-scale shaking. The existing technology cannot reinforce the long shaft type gear shaft, which makes it impossible to complete the processing of its end smoothly. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a drilling machine for gear shaft processing. By setting up a fixed tube seat, abutment seat, hard block, and elastic ball rod, this utility model enables multiple support points to be formed on the outside of the gear shaft during drilling, while ensuring easy disassembly and assembly of the gear shaft. This ensures that the gear shaft is centered and fixed, and absorbs the vibration generated during drilling, effectively improving the processing accuracy and quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling machine for gear shaft processing, comprising a base and a first support frame. The first support frame is fixedly mounted on one side of the upper end face of the base. A three-jaw chuck is mounted on the first support frame. Multiple jaws are evenly slidably arranged along the circumferential direction on the end face of the three-jaw chuck. A drill is slidably mounted on one side of the three-jaw chuck. Multiple fixed tube seats are evenly arranged along a straight line between the three-jaw chuck and the drill. Clamping cylinders are arranged circumferentially on the annular surface of each fixed tube seat. The output end of each clamping cylinder is connected to an abutment seat. A hard block is mounted below the abutment seat. The hard block and the abutment seat are connected by a spring. An elastic tube is connected between the upper end face of the hard block and the inner end face of the abutment seat. The arrangement of the hard block and the elastic tube can form multi-point support and absorb the vibration generated during drilling, ensuring stability.

[0007] Preferably, each of the grippers is provided with a detachable connecting cylinder on its exterior, and a clamping block is provided on the inner end face of the connecting cylinder. The connection cylinder and clamping block ensure the effective fixation of one end of the gear shaft.

[0008] Preferably, a roughened annular plate is provided on the outer surface of the spring and the bottom end face of the abutment seat. The roughened annular plate increases the contact area with the outside of the gear shaft, thereby improving the clamping and fixing effect.

[0009] Preferably, the bottom outer circular surface of the abutment seat is provided with a plurality of outwardly inclined elastic rods. The provision of elastic rods allows the device to adapt to more fixing requirements.

[0010] Preferably, the outer arc surface of the clamping block is provided with multiple anti-slip grooves. The anti-slip grooves improve the clamping force of the clamping block.

[0011] Preferably, a second support frame is provided on one side of the upper end face of the base, and a push cylinder is provided on the end face of the second support frame, the output end of the push cylinder being connected to the punch.

[0012] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0013] (1) By setting up a fixed tube seat, abutment seat, hard block and elastic ball rod, this utility model can form multiple support points on the outside of the gear shaft when drilling, so that the gear shaft can be fixed in the center and absorb the vibration generated by drilling, which effectively improves the processing accuracy and quality.

[0014] (2) Through the special layout of the fixed tube seat and the clamping cylinder, the long-stroke gear shaft can not only complete the effective processing, but also reduce the interference during disassembly and installation, effectively improving the disassembly and installation efficiency and ensuring the processing efficiency.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Example 1:

[0023] refer to Figure 1-6 A drilling machine for gear shaft processing includes a base 51 and a first support frame 52. The first support frame 52 is fixedly mounted on one side of the upper end face of the base 51. A three-jaw chuck 54 is mounted on the first support frame 52. Multiple jaws 67 are evenly slidably mounted on the end face of the three-jaw chuck 54 in the circumferential direction. A drill 57 is slidably mounted on one side of the three-jaw chuck 54. Multiple fixed tube seats 55 are evenly mounted in the straight line between the three-jaw chuck 54 and the drill 57. Clamping cylinders 56 are arranged circumferentially on the annular surface of each fixed tube seat 55. The output end of the clamping cylinder 56 is connected to an abutment seat 61. A hard block 62 is mounted below the abutment seat 61. The hard block 62 and the abutment seat 61 are connected by a spring 63. An elastic tube 64 is connected between the upper end face of the hard block 62 and the inner end face of the abutment seat 61.

[0024] Specifically, the three-jaw chuck 54 is existing technology and will not be elaborated on in this solution. When the gear shaft needs to be clamped, the operator places one end of the gear shaft between multiple jaws 67, and then the three-jaw chuck 54 cooperates with the jaws 67 to complete the clamping of the gear shaft. The drill 57 drills a hole at the other end of the gear shaft. The drill 57 is existing technology and will not be elaborated on in this solution.

[0025] Three fixed tube seats 55 are arranged in front of the three-jaw chuck 54 and the punch 57. Each of the three fixed tube seats 55 has only one clamping cylinder 56 and a part connected to the output end of the clamping cylinder 56 on its annular surface. The multiple clamping cylinders 56 are distributed along the circumference. The annular surface of each of the three fixed tube seats 55 can be provided with an opening. The direction of the opening is set according to actual needs, as shown in the other two in the figure. One of the figures is a complete ring shape, which is used to represent the basic shape of the fixed tube seat 55. In actual operation, the opening is arranged. The three fixed tube seats 55 are all concentric and coaxial. The setting of the opening allows the gear shaft to be quickly placed between the multiple fixed tube seats 55 to complete the reinforcement treatment and facilitate disassembly and maintenance. The multiple fixed tube seats 55 are set to ensure the fixed stroke and improve the fixing effect. However, only one clamping part of the clamping cylinder 56 is arranged on each fixed tube seat 55. On the one hand, it can avoid unnecessary waste, and on the other hand, it can reduce interference during picking and improve disassembly and assembly efficiency.

[0026] After the gear shaft is placed in multiple fixed tube seats 55, multiple clamping cylinders 56 can push the abutment seat 61 to move towards the outer surface of the gear shaft, thereby pushing the hard block 62 at one end of the abutment seat 61 to move. The hard block 62 is made of hard metal material with a roughened outer end surface. The spring 63 allows the hard block 62 to move up and down, while the elastic tube 64 forms an elastic support on the top of the hard block 62. When the abutment seat 61 pushes the hard block 62 to clamp the outside of the gear shaft, on the one hand, the hard block 62 can be pressed inward to ensure the clamping force, and on the other hand, the spring 63 and the elastic tube 64 can absorb vibration, thereby improving the stability of the gear shaft during drilling and improving the drilling accuracy.

[0027] refer to Figure 5 A rough-surfaced ring plate 66 is provided on the bottom end face of the abutment seat 61 outside the spring 63.

[0028] Specifically, the roughened ring plate 66 increases the contact area between the abutment seat 61 and the outer surface of the gear shaft. At the same time, the roughened ring plate 66 is made of a hard material, which allows the roughened ring plate 66 to provide a rigid clamping surface on the outside of the gear shaft, thereby improving the fixing effect.

[0029] refer to Figure 6Each gripper 67 is provided with a detachable connecting cylinder 59 on its exterior, and a clamping block 60 is provided on the inner end face of the connecting cylinder 59.

[0030] Specifically, the connecting cylinder 59 and the gripper 67 are fixed together by bolt thread holes. The clamping block 60 on the inner end face of the connecting cylinder 59 is arc-shaped and fan-shaped, which can effectively increase the clamping area and improve the clamping tightness of the equipment on the gear shaft.

[0031] refer to Figure 6 Multiple anti-slip grooves 68 are provided on the outer arc surface of the clamping block 60.

[0032] Specifically, the anti-slip groove 68 increases the contact friction of the clamping surface of the clamping block 60, thereby improving the clamping and fixing effect.

[0033] refer to Figure 1 A second support frame 53 is provided on one side of the upper end face of the base 51, and a push cylinder is provided on the end face of the second support frame 53. The output end of the push cylinder is connected to the punch 57.

[0034] Specifically, the output end of the push cylinder can push the drill 57 to move, thereby completing the drilling process on one end face of the gear shaft.

[0035] Example 2:

[0036] Based on or differing from Embodiment 1, refer to Figure 5 Multiple outwardly inclined elastic clubs 65 are provided on the outer circular surface of the bottom of the abutment seat 61.

[0037] Specifically, the outer end face of the elastic ball rod 65 is hemispherical. Since there are multiple gear surfaces on the outside of the gear shaft, the contact seat 61 contacts the gear surface, resulting in poor overall fixing effect. However, the multiple outwardly inclined elastic ball rods 65 can contact as many gear surfaces as possible, forming multiple points of support, which allows the equipment to fix the gear surface part, improving the applicability and practical effect of the equipment.
