Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of gear drilling equipment, and in particular to a drilling tool for gear processing. Background Technology
[0002] In the gear manufacturing process, "drilling" usually refers to machining center holes, positioning holes, weight reduction holes, assembly holes, or through holes on gear blanks or finished gears. These holes are crucial for the subsequent installation, transmission, weight reduction, balance, or connection with other components of the gear.
[0003] The existing publication number CN212094710U, entitled "A Gear Drilling Device," includes a frame and a gear clamping mechanism and a pressing mechanism mounted on the frame. The pressing mechanism includes a fixed block mounted on the frame, a telescopic rotary electric cylinder fixedly connected to the fixed block, and a pressing tap positioned below the telescopic rotary electric cylinder. The pressing tap includes a shank and a cutting edge, the shank and cutting edge being integrally formed, with the cutting edge extending towards the pressing mechanism. The cutting edge includes multiple circumferentially distributed tapered tooth units, extending along the long axis of the pressing tap. Adjacent tapered tooth units have oil grooves extending along the long axis of the pressing tap. Each tapered tooth unit is smoothly formed by a first inclined surface, an arc surface, and a second inclined surface, with multiple evenly distributed ridges on the first inclined surface, arc surface, and second inclined surface. This invention has the following advantages: it avoids the generation of metal shavings splashing, improves the processing quality of gears, and increases work efficiency.
[0004] However, when the aforementioned gears are drilled, a triangular chuck is used to hold the gears. During the holding process, the jaws of the triangular chuck squeeze the formed teeth of the gears. When the drill bit is drilling, the torque generated by the drill bit causes the jaws to squeeze the formed teeth of the gears, resulting in wear on the teeth and deformation damage to the gears. Utility Model Content
[0005] This invention solves the problems in related technologies and proposes a drilling tool for gear processing.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a gear drilling tool, including a support and a drilling component. The support includes a bracket and a clamping component. The clamping component is vertically arranged above the bracket. The clamping component includes a clamping cylinder and a limiting groove block. The clamping cylinder is vertically fixedly assembled on the top surface of the bracket. Multiple assembly grooves are evenly and vertically arranged on the inner wall of the clamping cylinder. The limiting groove block is vertically slidably assembled in the multiple assembly grooves of the clamping cylinder. A V-shaped groove is vertically opened on the inner side of the limiting groove block. An assembly bolt is vertically installed through the top of the limiting groove block. The assembly bolt is threaded into the assembly groove of the clamping cylinder. The drilling component includes a rod frame, a hole plate, and a drilling motor. The rod frame is vertically fixed on one side of the bracket. The hole plate is vertically slidably assembled on the rod frame. The drilling motor is vertically fixed on the hole plate. A drill rod is vertically fixed at the output end of the drilling motor.
[0007] As a preferred embodiment, a rubber pad is provided on the inner wall of the V-shaped groove of the limiting groove block, and the rubber pad is fixed on the inner wall of the V-shaped groove of the limiting groove block.
[0008] As a preferred embodiment, a damping rod is vertically fixed on the top surface of the bracket, and the top end of the damping rod is fixed on the clamp.
[0009] As a preferred embodiment, a support spring is vertically sleeved on the outside of the damping rod, and the two ends of the support spring are fixed to the top surface of the bracket and the clamp.
[0010] As a preferred embodiment, a pusher hydraulic rod is vertically fixed in the middle of the bracket, and a pusher plate is horizontally fixed at the output end of the pusher hydraulic rod.
[0011] As a preferred embodiment, a drilling hydraulic rod is vertically fixed at the top of the rod frame, and the output end of the drilling hydraulic rod is fixed on the top surface of the orifice plate.
[0012] As a preferred embodiment, a return spring is vertically fitted on the rod frame, and the two ends of the return spring are fixed to the orifice plate and the top of the rod frame, respectively.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, a suitable size limiting slot block is selected and inserted into the assembly slot of the clamp according to the size of the gear teeth to be drilled. Then, the limiting slot block is fixed in the clamp using assembly bolts. The gear to be drilled is inserted into the clamp, and the teeth on the gear are inserted into the V-shaped groove of the limiting slot block. The hole plate on the rod frame of the drilling component slides vertically down, driving the drill rod at the output end of the drilling motor to drill the gear. Thus, when drilling, the limiting slot block engages with the gear teeth, avoiding the problem that the torque generated by the drill bit causes the chuck to squeeze the formed teeth of the gear, and the chuck to wear the teeth, causing deformation damage to the gear. This improves the external stability of the gear drilling. Attached Figure Description

[0017] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0018] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

[0021] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
[0022] like Figures 1 to 5 As shown, a gear drilling tool includes a support 1 and a drilling component 2. The support 1 includes a bracket 11 and a clamping component 12. The clamping component 12 is vertically arranged above the bracket 11. The clamping component 12 includes a clamping cylinder 121 and a limiting groove block 123. The clamping cylinder 121 is vertically fixedly assembled on the top surface of the bracket 11, and multiple assembly grooves 122 are evenly and vertically arranged on the inner wall of the clamping cylinder 121. The limiting groove block 123 is vertically and slidably assembled in the multiple assembly grooves 122 of the clamping cylinder 121. The inner side of 23 is vertically provided with a V-shaped groove, and the top of the limiting groove block 123 is vertically connected with an assembly bolt 124, and the assembly bolt 124 is threaded in the assembly groove 122 of the clamp 121. The drilling component 2 includes a rod frame 21, a hole plate 24 and a drilling motor 25. The rod frame 21 is vertically fixed to one side of the bracket 11, and the hole plate 24 is vertically slidably assembled on the rod frame 21. The drilling motor 25 is vertically fixed on the hole plate 24, and the output end of the drilling motor 25 is vertically fixed with a drill rod 26. A rubber pad 125 is provided on the inner wall of the V-shaped groove of the limiting slot 123, and the rubber pad 125 is fixed on the inner wall of the V-shaped groove of the limiting slot 123. In use, the appropriate size of the limiting slot 123 is selected according to the size of the gear teeth to be drilled and inserted into the assembly groove 122 of the clamp 121. Then, the limiting slot 123 is fixed in the clamp 121 by the assembly bolt 124. The gear to be drilled is inserted into the clamp 121, and the teeth on the gear are inserted into the V-shaped groove of the limiting slot 123. The hole plate 24 on the rod frame 21 of the drilling component 2 slides vertically down, driving the drill rod 26 at the output end of the drilling motor 25 to drill the gear. Thus, when drilling, the limiting slot 123 engages with the teeth of the gear, avoiding the problem that the torque generated by the drill bit causes the chuck to squeeze the formed teeth of the gear, and the chuck to wear the teeth, causing deformation damage to the gear. This improves the external stability of the gear drilling.
[0023] In one embodiment, such as Figure 3 As shown, a damping rod 15 is vertically fixed on the top surface of the bracket 11, and the top end of the damping rod 15 is fixed on the clamp 121. A support spring 16 is vertically sleeved on the outside of the damping rod 15, and both ends of the support spring 16 are fixed on the top surface of the bracket 11 and the clamp 121. In use, the damping rod 15 supports the clamp 121. When the clamp 121 clamps the gear, the vibration generated by the gear opening causes the damping rod 15 to extend and the support spring 16 to deform and absorb the vibration. The deformation potential energy of the support spring 16 is canceled by the damping rod 15, ensuring the stability of the clamp 121 support.
[0024] In one embodiment, such as Figure 5As shown, a pusher hydraulic rod 13 is vertically fixed in the middle of the bracket 11, and a pusher plate 14 is horizontally fixed at the output end of the pusher hydraulic rod 13. When the gear is used after the hole is opened, the pusher hydraulic rod 13 is activated to extend and drive the pusher plate 14 to move upward, pushing the gear in the clamp 121 out.
[0025] In one embodiment, such as Figure 5 As shown, a drilling hydraulic rod 22 is vertically fixed at the top of the rod 21, and the output end of the drilling hydraulic rod 22 is fixed on the top surface of the hole plate 24. A return spring 23 is vertically sleeved on the rod 21, and the two ends of the return spring 23 are fixed to the hole plate 24 and the top of the rod 21, respectively. During use, the hole plate 24 on the rod 21 of the drilling component 2 slides down vertically, compressing the return spring 23 to deform, which drives the drill rod 26 at the output end of the drilling motor 25 to open the gear.
[0026] In this embodiment, during use, a suitable size limiting slot 123 is selected and inserted into the assembly slot 122 of the clamping sleeve 121 according to the size of the gear teeth to be drilled. Then, the limiting slot 123 is fixed in the clamping sleeve 121 using the assembly bolt 124. The gear that needs to be drilled is inserted into the clamping sleeve 121, and the teeth on the gear are inserted into the V-shaped slots of the limiting slot 123. The hole plate 24 on the rod frame 21 of the drilling component 2 slides vertically down, driving the drill rod 26 at the output end of the drilling motor 25 to drill the gear. Thus, when drilling, the limiting slot 123 engages with the teeth of the gear. The clamping sleeve 121 is supported by the damping rod 15. The vibration generated by the gear drilling in the clamping sleeve 121 causes the damping rod 15 to extend and the support spring 16 to deform and absorb the vibration. The deformation potential energy of the support spring 16 is canceled by the damping rod 15, ensuring the stability of the clamping sleeve 121 support.
[0027] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
