Description

Technical Field

[0001] The utility model belongs to the technical field of gear processing, and in particular relates to a processing device for producing transmission gears. Background Art

[0002] Gears are an efficient and convenient transmission structure, widely used for their many advantages, including stable transmission, compact structure, and high transmission efficiency. During the gear manufacturing process, manufacturers often need to heat treat the gear surface to increase its surface hardness, thereby extending its service life and increasing its wear resistance.

[0003] For example, a processing device for transmission gear production disclosed in patent application number CN202321294100.0 includes a support plate, on which a plurality of limiting mechanisms are provided, wherein the limiting mechanisms include a fixed seat connected to the support plate, and a limiting rod is provided on the fixed seat, and the limiting rod is adapted to the diameter of the inner ring of the gear. The fixed seat of the present application forms a support step for the gear, so that the contact surface between the heat treatment medium and the gear is larger, the gear is heated evenly, and the consistency of the heat treatment of the gears in the same furnace is improved. The limiting rod forms a limit on the inner hole of the gear to prevent the gear from slipping during the heat treatment process, thereby ensuring the quality of the gear heat treatment.

[0004] The existing technology considers the problem of gear fixing during gear processing and heat treatment. The existing technology forms a limiting mechanism by setting a fixing seat, a limiting rod, etc. However, in actual use, there are still certain shortcomings:

[0005] 1. In order to reduce the shielding area of ​​the gear, some existing technologies have fixed assemblies with support plates that cannot be adjusted in size, which makes it impossible to use gears of different sizes in the limit assembly.

This setting increases the shielding area of ​​the gear, which in turn reduces the heat treatment effect of the device.

[0006] 2. During the heat treatment process, the existing technology often only limits and fixes the two end faces of the gear when limiting the gear, but lacks circumferential limitation and corresponding stabilization measures. During the heat treatment process, due to environmental factors such as equipment vibration, the gear is prone to slip, resulting in friction and deformation on the gear surface, increasing the defective rate.

DETAILED DESCRIPTION

[0030] 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.

[0031] Example 1:

[0032] Reference Attachment Figure 1 , Attachment Figure 2 And attached Figure 3 A processing device for transmission gear production includes a base 10, a processing seat 16 is fixedly provided on the upper end surface of the base 10, a sliding top cover 14 is slidably provided above the processing seat 16, a first support plate 11 is also fixedly provided on the upper end surface of the base 10 above the sliding top cover 14, two symmetrical first drive motors 12 are fixedly provided on the upper end surface of the first support plate 11, two first screw rods 13 are connected to the lower end surface of the first support plate 11 below the two first drive motors 12, and the two first screw rods 13 are both transmission-connected to the sliding top cover 14 above the processing seat 16. A processing space for gear heat treatment is provided in the processing seat 16; the processing personnel can drive the two first screw rods 13 to rotate by controlling the two first drive motors 12, and drive the sliding top cover 14 thereon to move up and down to open or close the processing seat 16.

[0033] For further information, see the attached Figure 3 With attached Figure 5 A plurality of induction coils 15 are fixedly provided on the lower end surface of the sliding top cover 14. When the sliding top cover 14 is closed above the processing seat 16, the induction coils 15 can just perform heat treatment processing on the plurality of gears in the processing seat 16.

[0034] For further information, see the attached Figure 3 , Attachment Figure 5 , Attachment Figure 7 And attached Figure 8 Two diagonally arranged second drive motors 17 are fixedly mounted on the lower end surface of the bottom of the processing seat 16. The output end of each second drive motor 17 is connected to a second screw rod 18 installed inside the processing seat 16. A second support plate 20 is also installed on the two second screw rods 18 inside the processing seat 16. The two second drive motors 17 at the bottom of the processing seat 16 can drive the two second screw rods 18 inside the processing seat 16 to rotate, and drive the second support plate 20, which is in transmission with the two second screw rods 18, to move up and down. The two second screw rods 18 are arranged diagonally to enhance the stability of the second support plate 20 when sliding up and down. The second support plate 20 is equipped with a part for fixing gears. Before or after processing, the processing personnel can raise the second support plate 20 to install or remove the gears.

[0035] For further information, see the attached Figure 3 , Attachment Figure 4 , Attachment Figure 6 And attached Figure 10 A plurality of telescopic rods 22 are fixedly provided on the second support plate 20 below the induction coil 15. A sliding support platform 21 is slidingly provided on the upper portion of the telescopic rods 22. A central fixing rod 28 is fixedly provided on the upper end surface of the sliding support platform 21. Two symmetrical first fixing components are respectively provided on the outer circular surface of the central fixing rod 28 in the vertical direction. A thread 29 is provided on the upper part of the central fixing rod 28, and the thread 29 can be mutually transmitted and cooperated with the first fixing component above.

[0036] The first fixing component on the lower side is located above the sliding support platform 21, but there is still a certain space between its lower end surface and the upper end surface of the sliding support platform 21 to prevent the sliding support platform 21 from blocking the lower end surface of the gear during processing; the first fixing component on the upper side is detachable. With the cooperation of the thread 29, the processing personnel can rotate and remove the first fixing component on the upper side, place the gear hole along the center fixing rod 28 on the upper end surface of the first fixing component on the lower side, and then reinstall the first fixing component on the upper side. After fixing, the first fixing component on the upper side should be close to the upper end surface of the gear.

[0037] For further information, see the attached Figure 4 , Attachment Figure 7 And attached Figure 8The first fixing assembly includes a polygonal fixing plate 30. A polygonal rotating plate 31 is mounted on one side of the polygonal fixing plate 30, which is rotatable relative to the polygonal fixing plate 30. A plurality of third sliding slots 35 are fixedly mounted on the polygonal rotating plate 31. A plurality of folding rods 32 are rotatably connected to the polygonal rotating plate 31, and one end of the folding rods 32 slides within the third sliding slots 35. Rotating the polygonal rotating plate 31 rotates the plurality of folding rods 32 connected thereto, achieving an opening and closing effect. This allows the first fixing assembly to accommodate gears of varying sizes. Both the polygonal fixing plate 30 and the polygonal rotating plate 31 are hollowed out, reducing obstruction and improving the heat treatment process for the gears.

[0038] For further information, see the attached Figure 4 , Attachment Figure 8 , Attachment Figure 9 And attached Figure 10 A second fixing assembly is also provided on the outer side of the telescopic rod 22 on the upper end surface of the second support plate 20. The second fixing assembly includes a first slide groove 24 provided on the upper end surface of the second support plate 20 on one side of the sliding support platform 21. The first slide groove 24 is only provided with a single slide. The sliding support platform 21 is also rotatably provided with a first support rod 26 that slides and cooperates with the first slide groove 24.

[0039] Furthermore, the second fixing assembly also includes a second slide groove 25 arranged on the upper end surface of the second support plate 20 on the other side of the sliding support platform 21. The second slide groove 25 is arranged in a ring shape and has multiple slideways arranged in the circumferential direction on the ring surface. A rotating ring 34 is rotatably provided on the lower end surface of the sliding support platform 21, and a second support rod 27 that can slide with the second slide groove 25 is rotatably provided on one side of the rotating ring 34.

[0040] After the upper fixing assembly is pressed down and assembled, it will drive the sliding support platform 21 to move downward together to overcome the spring 23. The downward movement of the sliding support platform 21 will cause the first support rod 26 to slide outward in the first slide groove 24 and change the angle of the first slide groove 24 so that its upper end is stuck between the tooth grooves of the gear.

[0041] Similarly, when the sliding support platform 21 moves downward and rotates the first support rod 26, it also causes the second support rod 27 to slide outward from the slideway, and its upper end rotates and engages in the tooth groove. Taking into account the different tooth thicknesses of gears of different sizes and the fact that the number of teeth can be odd or even, the rotating ring 34 at the lower end of the sliding support platform 21 can drive the second support rod 27 to rotate in the second slide groove 25, adjusting the angle to ensure that the upper end of the second support rod 27 can properly engage between the tooth grooves to limit the circumferential position of the gear. Before the sliding support platform 21 is pressed downward, the second support rod 27 rotates in the second slide groove 25 in cooperation with the rotating ring 34. When the sliding support platform 21 is pressed downward, the second slide groove 25 slides and engages in one of the slideways, and the rotating ring 34 and the second support rod 27 will no longer be able to slide circumferentially.

[0042] Specifically, initially, the processing personnel control multiple first drive motors 12 to start, and multiple first drive motors 12 drive the first screw rod 13 to rotate and drive the sliding top cover 14 on it to move upward to open the processing seat 16. Then the processing personnel control multiple second drive motors 17 to start again, and multiple second drive motors 17 drive the second screw rod 18 connected thereto to rotate and drive the second support plate 20 in the processing seat 16 to drive the parts thereon to move upward; the second support plate 20 moves up to the top of the processing seat 16, and the parts of the fixed gear on the second support plate 20 are higher than the upper end surface of the processing seat 16. The processing personnel can easily install multiple gears on the second support plate 20.

[0043] When installing the gear, with the cooperation of the thread 29, the processing personnel first rotate and remove the first fixing component on the upper side; then, the processing personnel adjust the upper and lower first fixing components respectively according to the size requirements of different gears, and rotate the polygonal rotating plate 31, so that the folding rod 32 rotatably connected between the polygonal fixing plate 30 and the polygonal rotating plate 31 rotates and produces an opening and tightening effect. The specific size and rotation angle of the first fixing component refer to the actual production requirements, and this solution does not impose too many restrictions; after the adjustment is completed, the processing personnel put the gear along the central fixing rod 28 into the upper end face of the lower first fixing component; then, The processing personnel can rotate the second support rod 27 to the corresponding position by rotating the ring 34, and tighten the first fixing component on the upper side to limit and fix the gear axially. When the processing personnel tighten the first fixing component on the upper side, the sliding support platform 21 on the lower side is pressed downward, and the first support rod 26 and the second support rod 27 on both sides slide outward in the first slide groove 24 and the second slide groove 25. The first support rod 26 is fixed by the second slide groove 25 and cannot rotate in the circumferential direction of the gear. The angle between the first support rod 26 and the second support rod 27 changes, and the upper ends of both are stuck in the tooth groove of the gear to limit and fix the gear circumferentially.

[0044] After all the gears are fixed, the processing personnel control multiple second drive motors 17 to drive multiple second screw rods 18 to reverse, and make the second support plate 20 drive multiple parts thereon to move downward together with the gears; then, the processing personnel control multiple first drive motors 12 to drive multiple first screw rods 13 to reverse, so that the sliding top cover 14 with transmission cooperation thereon moves downward to the upper end surface of the processing seat 16 to cover it tightly; in the above-mentioned setting relationship, when the sliding top cover 14 covers the upper end surface of the processing seat 16, the induction coil 15 on the lower end surface of the processing seat 16 will cover the outer periphery of the gear, and then the induction coil 15 can perform heat treatment on the gear. The specific induction coil 15 is existing technology and will not be elaborated in detail in this scheme.

[0045] After the processing is completed, the processing personnel only need to open the sliding top cover 14 and move the second support plate 20 upward to remove the multiple gears that have been processed. The operation steps are similar to those described above and will not be elaborated in detail in this solution.

[0046] Example 2:

[0047] Reference Attachment Figure 4 With attached Figure 6 A tightening handle 33 is also fixed above the first fixing component on the upper side. Considering that the processing personnel need to install and disassemble the tightening handle 33 with the cooperation of the thread 29, the setting of the tightening handle 33 can reduce the difficulty of operation and facilitate installation and disassembly by the processing personnel.

[0048] For further information, see the attached Figure 1 With attached Figure 7 As a further embodiment, in order to improve the degree of automation control of this equipment, a controller 19 is fixedly installed on the outside of the processing seat 16. After the processing personnel set the process and processing time of the gear heat treatment, the controller 19 can automatically issue instructions to control this equipment. The information exchange between the processing personnel and this equipment is also completed through the controller 19, which reduces the difficulty of operation and improves the efficiency of spray processing.
