Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a chamfering machine for efficiently processing various types of gears. Background Technology

[0002] Gear chamfering refers to the process of beveling or deburring the edges of gear teeth (especially the tooth tip and end face) during gear manufacturing, creating small bevels or rounded transitions. While seemingly simple, this process significantly impacts gear performance and lifespan. After cutting or grinding, sharp burrs easily form on the tooth edges. Chamfering eliminates these burrs, preventing injuries to personnel or adjacent parts during assembly or operation, improving operational safety, reducing stress concentration, enhancing gear strength, and improving meshing performance. Furthermore, gear chamfering increases the success rate of heat treatment and facilitates assembly and lubrication.

[0003] In the prior art, there is an invention patent with publication number "CN 106624193 A", publication date of 2017.05.10, and patent name "A horizontal CNC gear chamfering machine with tool magazine and its chamfering method". In this invention, the gear is first fixed by a tooling fixture, and then the chamfering cutter is brought close to the gear to be processed for processing. This requires multiple clamping and adjustment, which is not efficient. Utility Model Content

[0004] In view of the problems existing in the current gear chamfering process, this utility model is proposed.

[0005] Therefore, the problem to be solved by this utility model is the cumbersome clamping operation. This utility model adjusts the position of the gear to be processed so that it cooperates with the gear chamfering tool, making the adjustment of the position of the gear to be processed convenient and improving the processing efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency chamfering machine for processing various types of gears, comprising a base, a processing component, and a mounting component for mounting the workpiece to be processed. The processing component includes a tool holder connected above the base, on which a gear chamfering tool is rotatably connected. The mounting component includes a base plate in front of the tool holder, on which an adjusting seat is slidably connected. A transmission rod is hinged to the adjusting seat, and the end of the transmission rod away from the adjusting seat is hinged to a push-pull rod. An angle-adjustable sleeve is connected above the adjusting seat, and the workpiece to be processed is rotatably connected to the sleeve.

[0007] In this invention, the gear to be processed can mesh with the gear chamfering tool. Before chamfering, the position of the gear to be processed is adjusted. Before adjusting the position, it is assumed that the angle of the gear to be processed has been adjusted to a suitable position. Hold the push-pull rod and push it. The push-pull rod pushes the adjusting seat towards the position of the gear chamfering tool through the transmission rod. When the gear to be processed and the gear chamfering tool mesh, stop pushing the push-pull rod and hold the push-pull rod steady by hand. The gear chamfering tool rotates, and the gear to be processed rotates. After processing is completed, hold the push-pull rod to move the adjusting seat forward, that is, away from the tool holder. The gear chamfering tool stops rotating, and the adjusting seat moves to a suitable position. Release the push-pull rod, remove the chamfered gear, and then put a new gear to be processed on the sleeve. Repeat the above steps until all gears to be processed are chamfered. This invention makes it convenient to adjust the position of the gear to be processed. Simply hold the push-pull rod and push or pull it. After adjusting to the position, hold the push-pull rod steady by hand. It is easy to operate, more practical, and improves processing efficiency. It can be applied to gear chamfering operations.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1

[0026] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a chamfering machine for efficiently processing various types of gears, which can reliably realize the chamfering processing of the gear 400 to be processed.

[0027] A high-efficiency chamfering machine for processing various types of gears includes a base 100, a processing assembly 300, and a mounting assembly 200 for mounting the workpiece to be processed. The processing assembly 300 includes a tool holder 301 connected above the base 100, and a gear chamfering cutter 311 is rotatably connected to the tool holder 301. The mounting assembly 200 includes a base plate 201 in front of the tool holder 301, an adjusting seat 203 slidably connected to the upper side of the base plate 201, a transmission rod 211 hinged to the adjusting seat 203, and one end of the transmission rod 211 away from the adjusting seat 203 hinged to a push-pull rod 202. An angle-adjustable sleeve is connected above the adjusting seat 203, and the workpiece to be processed is rotatably connected to the sleeve.

[0028] The gear 400 to be processed can mesh with the gear chamfering cutter 311. Before chamfering, adjust the position of the gear 400 to be processed. Before adjusting the position, it is assumed that the angle of the gear 400 to be processed has been adjusted to a suitable position. Hold the push-pull rod 202 and push it. The push-pull rod 202 pushes the adjusting seat 203 towards the position of the gear chamfering cutter 311 via the transmission rod 211. When the gear 400 to be processed and the gear chamfering cutter 311 mesh, stop pushing the push-pull rod 202 and hold it steady by hand. The gear chamfering cutter 311 rotates, and the gear chamfering cutter 311 drives the gear 400 to be processed to rotate. The processing is completed. Hold the push-pull rod 202 and push it back. Pull rod 202 moves adjusting seat 203 forward, that is, away from tool holder 301. Gear chamfering cutter 311 stops rotating. Adjusting seat 203 moves to the appropriate position. Release push-pull rod 202, remove the chamfered gear, and then put a new gear 400 to be processed on the sleeve. Repeat the above steps until all gears 400 to be processed are chamfered. This utility model makes it convenient to adjust the position of the gears 400 to be processed. Simply hold push-pull rod 202 and push or pull it. After adjusting it to the correct position, hold push-pull rod 202 steady with your hand. It is easy to operate, more practical, and improves processing efficiency. It can be applied to gear chamfering operations.

[0029] Specifically, the processing assembly 300 also includes a drive motor 302. A motor base 314 is fixedly connected to the rear side of the tool holder 301, and the drive motor 302 is fixedly connected to the motor base 314. The drive motor 302 and the gear chamfering cutter 311 are connected in a transmission connection. An actuating rod 205 is detachably connected to the adjusting seat 203. A linkage switch 308 is fixedly connected to the upper side of the base 100 on one side of the tool holder 301 in the left-right direction. The linkage switch 308 is electrically connected to the drive motor 302, and the actuating rod 205 can abut against the linkage switch 308. An output shaft 316 is connected to the 02, and a drive wheel 315 is connected to the output shaft 316. A driven wheel 307 is rotatably connected to the tool holder 301. The drive wheel 315 is connected to the driven wheel 307 via a transmission belt 305. A first support seat 309 and a second support seat 306 are fixedly connected to the front side of the tool holder 301. A connecting shaft 310 is rotatably connected to the first support seat 309 and the second support seat 306. The gear chamfering cutter 311 is connected to the connecting shaft 310. The driven wheel 307 is connected to the end of the connecting shaft 310 that extends out of the second support seat 306.

[0030] An external controller is provided, and a linkage switch 308 (existing technology) is electrically connected to the controller. The controller is also electrically connected to the drive motor 302. The controller receives signals from the linkage switch 308 and controls the drive motor 302 to operate (its control structure is existing technology and is not the inventive point of this application). When the trigger rod 205 abuts against the linkage switch 308, the linkage switch 308 sends a trigger signal indicating that the trigger rod 205 is in position to the controller. The controller then controls the drive motor 302 to operate, causing the gear chamfering tool 311 to rotate and perform chamfering on the gear 400 to be processed. After processing is completed, the adjusting seat 203 is moved away from the tool holder 301, the trigger rod 205 leaves the linkage switch 308, and the controller controls the drive motor 302 to stop operating. By using the position of the gear 400 to be processed to link the drive motor 302, processing efficiency and reliability are improved.

[0031] Specifically, the adjusting seat 203 is detachably connected to two connecting brackets 206 arranged opposite each other in the left-right direction. Fasteners 210 are rotatably connected to the two connecting brackets 206. A connecting seat 207 is fixedly connected to the fastener 210 on the opposite side of the two connecting brackets 206. A sleeve is fixedly connected to the connecting seat 207. One end of the fastener 210 has an external thread and extends out of one connecting bracket 206. A first clamping nut 312 is threaded to one end of the fastener 210. The first clamping nut 312 is pressed against the outside of one connecting bracket 206.

[0032] The gear 400 to be processed can fit perfectly onto the sleeve and can rotate on the sleeve. Before processing, the angle of the gear 400 to be processed is adjusted to a suitable chamfer angle (the gear 400 to be processed can mesh with the gear chamfering cutter 311). The specific adjustment process is as follows: loosen the first clamping nut 312, rotate the connecting seat 207 to a suitable angle, tighten the first clamping nut 312, and the first clamping nut 312 presses against the outside of a connecting bracket 206 to fix the angle of the fastener 210, that is, fix the angle of the connecting seat 207, thereby realizing the adjustment of the installation angle of the gear 400 to be processed.

[0033] Example 2

[0034] Reference Figure 2 and Figure 3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment and can further facilitate the installation of the connecting bracket 206 and the adjusting seat 203.

[0035] Specifically, the connecting bracket 206 includes a horizontal connecting portion 2062 that fits against the upper side of the adjusting seat 203. A vertical connecting portion 2061 is fixed on the upper side of the horizontal connecting portion 2062. The connecting seat 207 is connected between the two vertical connecting portions 2061. At least two first fixing bolts 208 that are spaced apart in the front-back direction are threaded onto the horizontal connecting portion 2062. In this application, two first fixing bolts 208 that are spaced apart in the front-back direction are threaded onto the horizontal connecting portion 2062. Two sliding openings 2031 that are spaced apart in the left-right direction are opened on the adjusting seat 203. A sliding groove 2033 is opened on the adjusting seat 203 below the sliding opening 2031. The lower end of the first fixing bolt 208 can abut against the step 2032 of the adjusting seat 203 below the sliding opening 2031. A second clamping nut 209 is threaded onto the first fixing bolt 208 above the horizontal connecting portion 2062.

[0036] When the connecting bracket 206 moves to the appropriate position on the adjusting seat 203, the corresponding connecting bracket 206 is pressed down, and the two first fixing bolts 208 are screwed upwards respectively. When the lower end of the first fixing bolt 208 is pressed on the step 2032, the first fixing bolt 208 can no longer be screwed in. The second clamping nut 209 is rotated so that the second clamping nut 209 presses the horizontal connecting part 2062 on the upper side of the adjusting seat 203, thereby fixing the connecting bracket 206 and the adjusting seat 203. The connecting bracket 206 is easy to install.

[0037] Specifically, the end of the trigger rod 205 away from the linkage switch 308 in the left-right direction is threaded with a second fixing bolt 204. The lower end of the second fixing bolt 204 can abut against the step 2032. A third clamping nut is threaded on the second fixing bolt 204 above the adjusting seat 203.

[0038] Install corresponding length trigger rods 205 according to different gear sizes; after the position of trigger rod 205 on the adjusting seat 203 is determined, press the trigger rod 205 by hand to make the second fixing bolt 204 screw upward. When the lower end of the second fixing bolt 204 is pressed against the step 2032, the second fixing bolt 204 cannot be screwed upward further. Rotate the third clamping nut so that the second clamping nut 209 presses the trigger rod 205 against the upper side of the adjusting seat 203, thereby fixing the trigger rod 205 and the adjusting seat 203; when the adjusting seat 203 is moved towards the tool holder 301 by the push-pull rod 202, the trigger rod 205 will press against the linkage switch 308, thereby triggering the drive motor 302 to operate; conversely, when the push-pull rod 202 moves away from the tool holder 301, the trigger rod 205 leaves the linkage switch 308, and the drive motor 302 stops operating.

[0039] Example 3

[0040] Reference Figure 4 and Figure 5 This is the second embodiment of the present invention, which is based on the previous embodiment and can further improve the scope of application.

[0041] Specifically, the height of the tool holder 301 is adjustable. Specifically, a vertically arranged column 303 is fixedly connected to the base 100, the tool holder 301 is slidably connected to the column 303, an adjusting screw 313 is threadedly connected to the upper end of the column 303, the lower end of the adjusting screw 313 is rotatably connected to the tool holder 301, and a convenient rotating handle 304 is fixedly connected to the upper end of the adjusting screw 313.

[0042] When machining gears of different sizes, the height of the tool holder 301 needs to be adjusted. The specific adjustment process is as follows: forcefully rotate the rotary handle 304, which drives the adjusting screw 313 to rotate. The adjusting screw 313 rotates and rises and falls at the same time, which in turn drives the tool holder 301 to rise and fall. When the tool holder 301 is raised or lowered to a suitable height, stop rotating the rotary handle 304. This achieves the height adjustment of the tool holder 301 and improves its applicability.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
