Description

Technical Field

[0001] This invention relates to the field of universal grinding technology, and more specifically, to a gear chamfering device. Background Technology

[0002] In the intelligent manufacturing equipment industry, the gear chamfering device equipped on the universal grinding machine can precisely control the size, angle and shape of the chamfer, ensuring that the chamfering parameters of each gear are consistent. Precise chamfering can ensure smoother gear meshing and improve the stability and reliability of gear transmission.

[0003] A search of existing published literature reveals that patent publication number CN109676492A discloses a stepped gear grinding device. This technology utilizes an electric spindle mounted on a slant bed CNC lathe with a 30-degree inclined worktable. A grinding wheel dresser for grinding stepped gears is mounted on the electric spindle, effectively achieving grinding of the end face and outer diameter of the stepped gears with high precision, saving grinding wheels, and protecting the electric spindle from damage. However, this patent has the following drawbacks.

[0004] In the intelligent manufacturing equipment industry, gears require chamfering using universal grinding machines. However, because gears have multiple tooth grooves, chamfering requires rotating and switching operations on the interior of each groove individually, while also processing each tooth's edge surface. This traditional method makes it difficult to achieve simultaneous, constant-force grinding and chamfering of multiple tooth grooves during the unloading process. This not only significantly reduces the efficiency of unloading grinding and chamfering and increases the overall processing time, but also severely affects the accuracy of chamfering, easily leading to uneven chamfering and dimensional deviations, making it difficult to meet the dual requirements of high efficiency and high precision in intelligent manufacturing. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides the following technical solution: a gear circulating chamfering device, comprising a grinding machine sleeve, a recessed airbag, and a controller. The recessed airbag is fixedly located on the inner wall of the grinding machine sleeve, and a synchronous constant force grinding chamfering assembly is installed on the inner wall of the recessed airbag. The synchronous constant force grinding chamfering assembly includes multiple push plates fixedly installed on the inner wall of the recessed airbag. A spring bar is fixedly connected to one side of each push plate, and a side pressure plate is fixedly connected to one side of the spring bar. Two chamfering grinding heads are installed on the inclined surface of one side of the side pressure plate. Multiple L-shaped frames are fixedly connected to the upper surface of the grinding machine sleeve. An arc-shaped plate is fixedly connected to one side of the spring bar. The arc-shaped plate is fixedly connected to the side pressure plate. Two inclined columns are fixedly connected to the inner wall of the L-shaped frames. An L-shaped sleeve is slidably connected to the outer wall of each inclined column. The bottom end of the L-shaped sleeve is fixedly connected to the side pressure plate.

[0006] Preferably, each of the two adjacent side pressure plates is slidably connected to the L-shaped frame, and the chamfering grinding head is fixedly connected to the side pressure plate by bolts; the L-shaped sleeve is slidably connected to the L-shaped frame. An air supply pipe is fixedly connected to the top of the recessed airbag; an electric valve is threadedly connected to the top of the air supply pipe, and a guide pipe is threadedly connected to the top of the electric valve; a pressure sensor is fixedly connected to one side of the outer wall of the guide pipe, and a booster fan is fixedly installed at the bottom of the guide pipe; the electric valve and the pressure sensor are both electrically connected to the controller, and the booster fan is electrically connected to the controller.

[0007] In this technology, the concave airbag, when compressed, squeezes multiple push plates, while the spring bar squeezes the arc-shaped plate. The side pressure plate drives the L-shaped sleeve to tilt and push, while simultaneously moving the L-shaped sleeve along the outer wall of the inclined column. The side pressure plate moves tilted on the lower surface of the L-shaped frame, driving two chamfering grinding heads to tilt and move, squeezing at the two corners of the inner wall of the gear tooth groove. Multiple chamfering grinding heads squeeze at the corners of the inner wall of multiple gear tooth grooves. When the pressure value detected by the pressure sensor matches the pressure value set by the controller, the controller will shut off the booster fan and the electric valve. As the gear moves upward to discharge material, the corners of its outer tooth grooves are simultaneously and forcefully squeezed and chamfered by the outer walls of the multiple chamfering grinding heads.

[0008] Preferably, the upper surface of the L-shaped frame is provided with a top surface synchronous grinding chamfering assembly; the top surface synchronous grinding chamfering assembly includes a sliding frame fixedly disposed on the upper surface of the L-shaped frame, a groove is formed on one side of the inner wall of the sliding frame, and a slider is slidably connected to the inner wall of the groove. A connecting strip is fixedly connected to one side of the slider. Spring pieces are provided above and below the connecting strip, and both spring pieces are fixedly connected to the sliding frame. A toothed shank is fixedly connected to one end of the connecting strip, and a guide toothed grinding strip is fixedly connected to the upper surface of the toothed shank. The spring pieces are fixedly connected to the guide toothed grinding strip, and another spring piece is fixedly connected to the toothed shank. The two spring pieces are symmetrically arranged about the connecting strip, and there is a gap between adjacent toothed shanks. Multiple guide toothed grinding strips are arranged in a circular, equidistant distribution. The cross-sectional area of ​​the upper surface of the toothed shank is larger than the cross-sectional area of ​​its bottom end, and the inner wall of the toothed shank is a rough surface.

[0009] In this technology, the corner of the upper surface edge of the gear contacts the inner wall of multiple toothed shanks. Because the cross-sectional area of ​​the upper surface of the toothed shank is larger than that of its lower surface, the toothed shank, under force, drives the guide toothed grinding strip to move backward. Simultaneously, the toothed shank also drives the lower spring sheet to undergo compressive deformation, thereby guiding the connecting strip to slide backward along the inner wall of the groove. Furthermore, the sliding frame can guide the slider backward, thus causing the corner of the upper surface edge of the gear to make inclined contact with multiple toothed shanks, achieving adaptive compression grinding chamfering.

[0010] Preferably, a positioning and feeding grinding assembly is installed at the bottom end of the grinding machine sleeve; the positioning and feeding grinding assembly includes a retractable electric cylinder installed at the bottom end of the grinding machine sleeve, a sleeve block is fixedly connected to the outer wall of the retractable electric cylinder, a controller is fixed to the outer wall of the sleeve block, and a movable electric cylinder is fixedly installed on the outer wall of the sleeve block and on the side adjacent to the controller. A circulating positioning seat is fixedly connected to the output end of the movable electric cylinder, the circulating positioning seat is used for cyclically inserting gears, and a base is fixedly connected to the lower surface of the movable electric cylinder. The output end of the retractable electric cylinder is fixedly connected to the grinding machine sleeve, and the retractable electric cylinder is electrically connected to the controller. The movable electric cylinder is electrically connected to the controller, and a through hole with a circular cross-sectional shape is opened on the inner wall of the circulating positioning seat. The base is used to support the movable electric cylinder, and a gap is provided between the upper surface of the circulating positioning seat and the lower surface of the grinding machine sleeve.

[0011] In application, the output end of the moving electric cylinder supports the circulating positioning seat, precisely positioning the gear shaft and inserting it into the gap inside the circulating positioning seat. Subsequently, the retracting electric cylinder drives the grinding machine sleeve to move downwards, the push plate moves the spring bar downwards synchronously, and the side pressure plate guides the two chamfering grinding heads to move downwards together. The grinding machine sleeve is fixed to the outside of the gear, and the multiple chamfering grinding heads correspond to each tooth groove of the gear, thereby achieving precise synchronous positioning operation.

[0012] The technical effects and advantages of this invention are as follows:

[0013] 1. This invention utilizes a synchronous constant-force grinding chamfering assembly. This assembly forces a recessed airbag to compress multiple push plates, ensuring that each side pressure plate drives two chamfering grinding heads to synchronously and precisely press against the inner corners of the gear tooth grooves. Multiple chamfering grinding heads can synchronously move in a circumferentially distributed, tilting and pressing against the inner corners of the gear tooth grooves according to a specified extrusion force. Simultaneously, a circulating positioning seat moves the gear upwards for material discharge. During discharge, the corners of the gear tooth grooves and the outer walls of the multiple chamfering grinding heads undergo synchronous constant-force grinding and chamfering. This reduces the tediousness and time-consuming nature of traditional tooth-groove-by-tooth operation. By utilizing the discharge time for synchronous constant-force grinding and chamfering of multiple gear tooth grooves, the grinding efficiency of the gear is significantly improved, achieving both high efficiency and high precision.

[0014] 2. This invention utilizes a top-surface synchronous grinding and chamfering assembly. When the corner of the upper surface edge of the gear contacts the inclined inner wall of multiple toothed racks, the special shape of the toothed racks (narrower at the bottom and wider at the top) causes the gear to squeeze and drive the guide grinding rack backward, causing the upper and lower spring pieces to deform under pressure. The L-shaped frame-supported sliding frame provides support for the spring pieces and simultaneously guides the connecting strip to move backward along the sliding groove, achieving inclined contact between the gear and multiple toothed racks for adaptive compression grinding and chamfering. This process can simultaneously and adaptively chamfer the upper surface edges of multiple toothed grooves of the gear, eliminating the need for individual operations, thus improving processing efficiency. Furthermore, the adaptive design ensures the quality of the chamfering until the gear is completely unloaded. The overall process is efficient and precise.

[0015] 3. This invention utilizes a positioning and feeding grinding assembly. The retracting electric cylinder moves the grinding machine sleeve downwards, positioning multiple chamfering grinding heads on various tooth grooves of the gear. Subsequently, the controller activates the moving electric cylinder again, pushing the circulating positioning seat and gear upwards. This achieves synchronous, constant-force grinding and chamfering of the multiple tooth groove corners on the gear's outer wall by the multiple chamfering grinding heads. This process not only efficiently completes the chamfering operation but also simultaneously enables the gear to move upwards for feeding, avoiding the cumbersome step-by-step chamfering and feeding processes of traditional methods. This significantly improves processing efficiency and ensures a smooth grinding production process.

[0016] In summary, firstly, during material discharge, multiple tooth groove corners on the outer wall of the gear are simultaneously subjected to constant-force extrusion grinding and chamfering with the outer walls of multiple chamfering grinding heads; secondly, during material discharge, multiple toothed chucks simultaneously perform synchronous adaptive chamfering on the edges of multiple tooth groove upper surfaces of the gear, achieving multi-point synchronous chamfering and synchronous material discharge operations, thus achieving intelligent synchronous universal grinding processing.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 8 As shown, this is a gear chamfering device. The device is equipped with a synchronous constant-force grinding chamfering assembly, a top-surface synchronous grinding chamfering assembly, and a positioning and discharge grinding assembly. The configuration of these components allows multiple tooth groove corners on the outer wall of the gear to be synchronously and consistently ground and chamfered against the outer walls of multiple chamfering grinding heads 6 during the discharge process. This effectively reduces the tediousness and time-consuming nature of traditional tooth groove-by-tooth operation and fully utilizes the discharge time for synchronous and consistent-force grinding and chamfering of multiple tooth grooves on the gear. Intelligent processing significantly improves the grinding efficiency of the gear while ensuring both high efficiency and high precision in grinding and chamfering. The specific structural settings of each component are as follows.

[0028] In this embodiment, as Figure 1 - Figure 5 As shown, the recessed airbag 2 is fixedly located on the inner wall of the grinding machine sleeve 1, and a synchronous constant force grinding chamfering assembly is installed on the inner wall of the recessed airbag 2; the synchronous constant force grinding chamfering assembly includes multiple push plates 3 fixedly installed on the inner wall of the recessed airbag 2, each push plate 3 is fixedly connected to one side of a spring strip 4, a side pressure plate 5 is fixedly connected to one side of the spring strip 4, and two chamfering grinding heads 6 are installed on one inclined surface of the side pressure plate 5.

[0029] Multiple L-shaped frames 7 are fixedly connected to the upper surface of the grinding machine sleeve 1. An arc-shaped plate 8 is fixedly connected to one side of the spring bar 4. The arc-shaped plate 8 is fixedly connected to the side pressure plate 5. Two inclined columns 10 are fixedly connected to the inner wall of the L-shaped frame 7. An L-shaped sleeve 9 is slidably connected to the outer wall of each inclined column 10. The bottom end of the L-shaped sleeve 9 is fixedly connected to the side pressure plate 5. Two adjacent side pressure plates 5 are slidably connected to the L-shaped frame 7. The chamfering grinding head 6 is fixedly connected to the side pressure plate 5 by bolts. The L-shaped sleeve 9 is slidably connected to the L-shaped frame 7.

[0030] In this embodiment, as Figure 3 - Figure 6 As shown, the top of the recessed airbag 2 is fixedly connected to an air supply pipe 11; the top of the air supply pipe 11 is threadedly connected to an electric valve 12, the top of the electric valve 12 is threadedly connected to a guide pipe 13, a pressure sensor 14 is fixedly connected to one side of the outer wall of the guide pipe 13, and a booster fan 15 is fixedly installed at the bottom of the guide pipe 13; the electric valve 12 and the pressure sensor 14 are both electrically connected to the controller 25, and the booster fan 15 is electrically connected to the controller 25 so that when the pressure value sensed by the pressure sensor 14 is the same as the pressure value set by the controller 25, the booster fan 15 and the electric valve 12 are shut off by the controller 25 to achieve constant pressure supply.

[0031] In this embodiment, as Figure 3 - Figure 7 As shown, the upper surface of the L-shaped frame 7 is provided with a top surface synchronous grinding chamfering assembly. The top surface synchronous grinding chamfering assembly includes a sliding frame 16 fixedly mounted on the upper surface of the L-shaped frame 7. A groove 17 is opened on one side of the inner wall of the sliding frame 16, and a slider 18 is slidably connected to the inner wall of the groove 17. A connecting strip 19 is fixedly connected to one side of the slider 18. There are spring pieces 20 above and below the connecting strip 19. Both spring pieces 20 are fixedly connected to the sliding frame 16. A toothed bar 21 is fixedly connected to one end of the connecting strip 19, and a guide toothed grinding strip 22 is fixedly connected to the upper surface of the toothed bar 21. The spring piece 20 is fixedly connected to the guide toothed grinding strip 22, and the other spring piece 20 is fixedly connected to the toothed bar 21. The two spring pieces 20 are symmetrically arranged about the connecting strip 19. There is a gap between two adjacent toothed bars 21. Multiple guide toothed grinding strips 22 are arranged in a circular and equidistant distribution. The cross-sectional area of ​​the upper surface of the toothed bar 21 is larger than the cross-sectional area of ​​its bottom end, and the inner wall of the toothed bar 21 is a rough surface.

[0032] In this embodiment, as Figure 1 - Figure 8As shown, a positioning and feeding grinding assembly is installed at the bottom of the grinding machine sleeve 1; the positioning and feeding grinding assembly includes a retractable electric cylinder 23 installed at the bottom of the grinding machine sleeve 1, a sleeve block 24 is fixedly connected to the outer wall of the retractable electric cylinder 23, a controller 25 is fixed on the outer wall of the sleeve block 24, and a movable electric cylinder 26 is fixedly installed on the outer wall of the sleeve block 24 and on the side adjacent to the controller 25.

[0033] The output end of the moving electric cylinder 26 is fixedly connected to a circulating positioning seat 27, which is used for cyclically engaging gears. A base 28 is fixedly connected to the lower surface of the moving electric cylinder 26. The output end of the retraction electric cylinder 23 is fixedly connected to the grinding machine sleeve 1, and the retraction electric cylinder 23 is electrically connected to the controller 25. The moving electric cylinder 26 is electrically connected to the controller 25. The inner wall of the circulating positioning seat 27 has a through hole with a circular cross-section. The base 28 is used to support the moving electric cylinder 26, and there is a gap between the upper surface of the circulating positioning seat 27 and the lower surface of the grinding machine sleeve 1.

[0034] The method of using the gear cyclic chamfering device of the present invention is as follows:

[0035] Step 1: During the cyclic positioning and feeding grinding process, the base 28 supports the moving electric cylinder 26, and the output end of the moving electric cylinder 26 supports the cyclic positioning seat 27, precisely positioning the shaft of the gear and inserting it into the gap inside the cyclic positioning seat 27. Subsequently, the moving electric cylinder 26 supports the sleeve block 24, and the controller 25 activates the retraction electric cylinder 23, which drives the grinding machine sleeve 1 to move downward. The grinding machine sleeve 1 then drives multiple push plates 3 to move downward, the push plates 3 push the spring strips 4 to move downward, the spring strips 4 drive the side pressure plates 5 to move downward, and the side pressure plates 5 ultimately drive the two chamfering grinding heads 6 to move downward. In this way, the grinding machine sleeve 1 is located outside the gear, and the multiple chamfering grinding heads 6 are precisely aligned with the multiple tooth grooves of the gear.

[0036] Step 2: During the simultaneous constant-force grinding and chamfering, the booster fan 15 is activated via controller 25, and the solenoid valve 12 is opened simultaneously. This causes the booster fan 15 to pressurize external air into the guide pipe 13, which is then pumped into the air supply pipe 11 via the solenoid valve 12. The air supply pipe 11 then delivers the pressurized air to the recessed airbag 2, causing it to compress multiple push plates 3. The push plates 3 then compress the spring strip 4, which in turn compresses the arc-shaped plate 8. Finally, the arc-shaped plate 8 and the spring strip 4 simultaneously apply pressure to the side pressure plate 5.

[0037] The side pressure plate 5 drives the L-shaped sleeve 9 to tilt and push, causing it to move synchronously along the inner wall of the L-shaped frame 7 and the outer wall of the inclined column 10. During this process, the side pressure plate 5 tilts and moves on the lower surface of the L-shaped frame 7, thereby driving the two chamfering grinding heads 6 to tilt and move, pressing against the two corner positions of the inner wall of the gear tooth groove. In this way, multiple chamfering grinding heads 6 can tilt and move synchronously in a circumferential distribution, pressing against the corner positions of the inner wall of multiple gear tooth grooves respectively.

[0038] When the pressure value detected by the pressure sensor 14 is consistent with the pressure value set by the controller 25, the controller 25 will shut down the booster fan 15 and the electric valve 12 to ensure that the multiple chamfering grinding heads 6 are pressed against the corner positions of the inner walls of the multiple tooth grooves of the gear according to the specified extrusion pressure, thereby realizing the intelligent synchronous constant force extrusion operation of the multiple chamfering grinding heads 6.

[0039] Subsequently, the controller 25 immediately activates the moving electric cylinder 26, pushing the circulating positioning seat 27 upward. The circulating positioning seat 27 drives the gear upward, so that the multiple tooth groove corners on the outer wall of the gear are synchronously and forcefully pressed and ground against the outer walls of the multiple chamfering grinding heads 6, while the gear can also move upward to discharge material.

[0040] Step 3: During the synchronous grinding and chamfering of the top surface, when the corner of the upper surface of the gear contacts the inner wall of multiple toothed shanks 21, since the cross-sectional area of ​​the upper surface of the toothed shank 21 is larger than that of its lower surface, the corner of the upper surface of the gear will continuously compress the inclined inner wall of the multiple toothed shanks 21, thereby causing the toothed shanks 21 to be forced and drive the guide toothed grinding strip 22 to move backward. The backward movement of the guide toothed grinding strip 22 will cause the upper spring 20 to deform under pressure, and at the same time, the toothed shanks 21 will also cause the lower spring 20 to deform under pressure.

[0041] During this process, the L-shaped frame 7 supports the sliding frame 16, which provides support for the two spring pieces 20. The toothed shank 21 presses against the connecting strip 19, causing the connecting strip 19 to slide backward along the inner wall of the groove 17. At the same time, the sliding frame 16 can guide the slider 18 backward, ensuring that the corner of the upper surface edge of the gear is in inclined contact with multiple toothed shanks 21, achieving adaptive extrusion grinding chamfering. In this way, the upper surface edges of multiple tooth grooves of the gear are simultaneously and adaptively chamfered until the gear contacts the upper row of multiple guide toothed grinding strips 22, completing the gear unloading process.

[0042] All contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used. Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
