Description

Technical Field

[0001] The present invention relates to the technical field of universal grinding, and more particularly to a gear circulating chamfering device. Background Art

[0002] In the intelligent manufacturing equipment industry, the gear circulation chamfering device equipped on the universal grinder has the ability to precisely control the size, angle and shape of the chamfer, ensuring that the chamfering parameters of each gear are consistent. Precise chamfering can ensure that the gears are more stable during meshing, thereby improving the stability and reliability of the gear transmission.

[0003] A search of existing public literature revealed patent publication number CN109676492A, which discloses a stepped gear grinding device. This technology utilizes an electric spindle with a 30-degree inclined worktable mounted on a slanted-bed CNC lathe. The spindle is equipped with a grinding wheel dresser for step gear grinding. This device effectively grinds the end faces and outer diameters of stepped gears, achieving 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 universal grinding machines for chamfering. However, because gears have multiple tooth grooves, chamfering requires rotating and switching operations within each tooth groove, and the edge position of the tooth upper surface also needs to be operated on each tooth. This traditional method makes it difficult to achieve synchronous fixed-force grinding and chamfering of multiple gear grooves during the discharge process. This not only significantly reduces the efficiency of discharge grinding and chamfering, increases the time consumption of the entire processing process, but also seriously affects the accuracy of chamfering, making it prone to uneven chamfering and dimensional deviation problems, making it difficult to meet the dual requirements of intelligent manufacturing for high efficiency and high precision. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides the following technical solutions: a gear circulation chamfering device, comprising a grinding machine sleeve, a recessed airbag and a controller, the recessed airbag being fixedly located on the inner wall of the grinding machine sleeve, the inner wall of the recessed airbag being installed with a synchronous fixed force grinding and chamfering assembly; the synchronous fixed force grinding and chamfering assembly comprising a plurality of push plates fixedly installed on the inner wall of the recessed airbag, one side of each of the push plates being fixedly connected with an elastic bar, one side of the elastic bar being fixedly connected with a side pressure plate, and two chamfering grinding heads being installed on an inclined surface of one side of the side pressure plate; a plurality of L-shaped frames being fixedly connected to the upper surface of the grinding machine sleeve, one side of the elastic bar being fixedly connected with an arc plate, the arc plate and the side pressure plate being fixedly connected, the inner wall of the L-shaped frame being fixedly connected with two inclined columns, the outer wall of each of the inclined columns being slidably connected with an L-shaped sleeve strip, and the bottom end of the L-shaped sleeve strip being fixedly connected to the side pressure plate.

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

[0007] During the application of this technology, the concave airbag is compressed to squeeze multiple push plates, and the elastic strip squeezes the arc plate. The side pressure plate drives the L-shaped sleeve to push obliquely, and at the same time, the L-shaped sleeve moves obliquely along the outer wall of the inclined column. The side pressure plate moves obliquely on the lower surface of the L-shaped frame, and drives the two chamfering grinding heads to move obliquely, squeezing the two corners of the inner wall of the gear tooth groove. Multiple chamfering grinding heads are squeezed on the inner wall corners of multiple tooth grooves of the gear respectively. When the pressure value detected by the pressure sensor is consistent with the pressure value set by the controller, the controller will turn off the boost fan and the electric valve. When the gear moves up to discharge the material, the multiple tooth groove corners on its outer wall and the outer walls of the multiple chamfering grinding heads are synchronously extruded, ground and chamfered with fixed force.

[0008] Preferably, the upper surface of the L-shaped frame is provided with a top surface synchronous grinding and chamfering assembly; the top surface synchronous grinding and chamfering assembly includes a sliding frame fixedly arranged on the upper surface of the L-shaped frame, a sliding groove is provided on one side of the inner wall of the sliding frame, and a slider is slidably connected to the inner wall of the sliding groove, a connecting bar is fixedly connected to one side of the slider, and spring plates are provided above and below the connecting bar, and both spring plates are fixedly connected to the sliding frame, one end of the connecting bar is fixedly connected to a tooth bend bar, and the upper surface of the tooth bend bar is fixedly connected to a guide tooth grinding bar, the spring plate is fixedly connected to the guide tooth grinding bar, and the other spring plate is fixedly connected to the tooth bend bar. The two spring plates are symmetrically arranged about the connecting bar, and there is a gap between two adjacent tooth bend bars, and a plurality of guide tooth grinding bars are arranged in a circular ring with equal spacing. The cross-sectional area of the upper surface of the tooth bend bar is larger than the cross-sectional area of its bottom end, and the inner wall of the tooth bend bar is a rough surface.

[0009] During the application of this technology, the corner position of the edge of the upper surface of the gear contacts the inner wall of multiple tooth bends. Since the cross-sectional area of the upper surface of the tooth bend is larger than the cross-sectional area of its lower surface, the tooth bend will drive the guide tooth grinding bar to move backward when it is subjected to force. At the same time, the tooth bend will also drive the spring sheet below to undergo extrusion deformation, thereby guiding the connecting bar to slide backward along the inner wall of the slide groove. In addition, the slide frame can guide the slider backward, so that the corner position of the edge of the upper surface of the gear is in oblique contact with multiple tooth bends, realizing adaptive extrusion grinding chamfering.

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

[0011] In this application, the output end of the moving electric cylinder supports the circular positioning seat, precisely positioning the gear shaft and inserting it into the gap within the circular positioning seat. Subsequently, the retracting electric cylinder drives the grinding sleeve downward, and the push plate drives the spring bar downward synchronously, while the side pressure plate guides the two chamfering grinding heads downward. The grinding sleeve is fixed to the outside of the gear, and the multiple chamfering grinding heads correspond to each gear tooth groove, achieving precise and synchronous positioning.

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

[0013] 1. The present invention uses synchronous fixed force grinding and chamfering components to force the recessed airbag to squeeze multiple push plates, ensuring that each side pressure plate drives the two chamfering grinding heads to synchronously and precisely squeeze the inner wall corners of the gear tooth grooves. Multiple chamfering grinding heads can synchronously move in a circular distribution state, thereby squeezing the inner wall corners of multiple tooth grooves of the gear according to the specified extrusion force. At the same time, the circular positioning seat drives the gear to move up and discharge. During the discharge process, the multiple tooth groove corners on the outer wall of the gear and the outer walls of the multiple chamfering grinding heads are synchronously extruded and chamfered with fixed force, reducing the tediousness and time-consuming operation of the traditional tooth groove one by one, and using the discharge time to perform synchronous fixed force grinding and chamfering on multiple tooth grooves of the gear, which significantly improves the grinding efficiency of the gear and takes into account both high efficiency and high precision.

[0014] 2. The present invention utilizes a top surface synchronous grinding and chamfering assembly. When the corner of the edge of the upper surface of the gear contacts the inclined surface of the inner wall of multiple tooth bends, due to the special shape of the tooth bend, which is narrow at the bottom and wide at the top, the gear is squeezed and drives the guide tooth grinding bar to move backward, causing the upper and lower spring pieces to be squeezed and deformed. The sliding frame supported by the L-shaped frame provides support for the spring piece, and at the same time guides the connecting bar to move backward along the slide groove, so that the gear can be in inclined contact with multiple tooth bends, and adaptively squeeze, grind and chamfer. This process can synchronously perform adaptive chamfering on the edges of the upper surfaces of multiple tooth grooves of the gear without the need to operate one by one, thereby improving processing efficiency, and the adaptive design ensures the quality of chamfering until the gear is discharged. The overall process is efficient and accurate.

[0015] 3. The present invention positions the discharge grinding assembly and activates the retracting electric cylinder to move the grinding sleeve downward, positioning the multiple chamfering grinding heads over the gear's tooth grooves. The controller then activates the moving electric cylinder again, pushing the circular positioning seat and gear upward, achieving synchronized, constant-force extrusion grinding of the multiple tooth groove corners on the gear's outer wall and the chamfering grinding heads. This process not only efficiently completes the chamfering operation but also simultaneously moves the gear upward for discharge, avoiding the cumbersome, step-by-step chamfering and discharge processes of traditional methods. This significantly improves processing efficiency and ensures a smooth grinding process.

[0016] In summary, firstly, during the discharge, multiple tooth groove corner positions on the outer wall of the gear and the outer walls of multiple chamfering grinding heads are synchronously subjected to fixed force extrusion grinding and chamfering; secondly, during the discharge, multiple tooth corner bars are synchronously used to perform synchronous adaptive chamfering on the edge positions of the upper surfaces of multiple tooth grooves of the gear, realizing multi-point synchronous chamfering and synchronous discharge operations, and achieving intelligent synchronous universal grinding processing.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The device is equipped with a synchronous fixed force grinding chamfering component, a top surface synchronous grinding chamfering component, and a positioning discharge grinding component. The configuration of these components enables the multiple tooth groove corner positions on the outer wall of the gear to be synchronously fixed force extrusion grinding and chamfering with the outer walls of multiple chamfering grinding heads 6 during the discharge process. This effectively reduces the tediousness and time-consuming operation of traditional tooth grooves one by one, and makes full use of the discharge time to perform synchronous fixed force grinding and chamfering on multiple tooth grooves of the gear. Intelligent processing significantly improves the grinding efficiency of gears, while taking into account the high efficiency and high precision of grinding and chamfering. The specific structural settings of each component are as follows.

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

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

[0030] In this embodiment, if Figure 3 - Figure 6 As shown, the top of the recessed airbag 2 is fixedly connected to the air supply pipe 11; the top of the air supply pipe 11 is threadedly connected to the electric valve 12, the top of the electric valve 12 is threadedly connected to the guide pipe 13, the outer wall side of the guide pipe 13 is fixedly connected to the pressure sensor 14, and the bottom end of the guide pipe 13 is fixedly installed with a booster fan 15; 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 until 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 closed by the controller 25 to achieve constant pressure supply.

[0031] In this embodiment, if Figure 3 - Figure 7 As shown, the upper surface of the L-shaped frame 7 is provided with a top surface synchronous grinding and chamfering assembly; the top surface synchronous grinding and chamfering assembly includes a slide frame 16 fixedly mounted on the upper surface of the L-shaped frame 7, a slide groove 17 is provided on one side of the inner wall of the slide frame 16, and a slider 18 is slidably connected to the inner wall of the slide groove 17. A connecting bar 19 is fixedly connected to one side of the slider 18, and spring clips 20 are provided above and below the connecting bar 19. The two spring clips 20 are fixedly connected to the slide frame 16, and one end of the connecting bar 19 is fixedly connected to a toothed bend bar 21, and the upper surface of the toothed bend bar 21 is fixedly connected to a guide toothed grinding bar 22. The spring clip 20 is fixedly connected to the guide toothed grinding bar 22, and the other spring clip 20 is fixedly connected to the toothed bend bar 21. The two spring clips 20 are symmetrically arranged about the connecting bar 19, and a gap is provided between adjacent toothed bend bars 21. The plurality of guide toothed grinding bars 22 are arranged equidistantly in a circular pattern. The cross-sectional area of the upper surface of the tooth bend bar 21 is larger than the cross-sectional area of the bottom end thereof, and the inner wall of the tooth bend bar 21 is a rough surface.

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

[0033] The output end of the movable electric cylinder 26 is fixedly connected to a circular positioning base 27, which is used for cyclically inserting gears. A base 28 is fixedly connected to the lower surface of the movable electric cylinder 26. The output end of the retracting electric cylinder 23 is fixedly connected to the grinding machine housing 1. The retracting electric cylinder 23 is electrically connected to the controller 25. The movable electric cylinder 26 and the controller 25 are electrically connected. The inner wall of the circular positioning base 27 has a through hole with a circular cross-section. The base 28 supports the movable electric cylinder 26. A gap is provided between the upper surface of the circular positioning base 27 and the lower surface of the grinding machine housing 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 discharge grinding process, the mobile electric cylinder 26 is supported by the base 28. The output end of the mobile electric cylinder 26 supports the cyclic positioning seat 27, and the shaft of the gear is precisely positioned and inserted into the gap inside the cyclic positioning seat 27. Subsequently, the controller 25 activates the retracting electric cylinder 23 by supporting the sleeve block 24 through the mobile electric cylinder 26, and the retracting electric cylinder 23 drives the grinding machine sleeve 1 to move downward. The grinding machine sleeve 1 then drives the multiple push plates 3 to move downward, and the push plates 3 push the spring bars 4 to move downward. The spring bars 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 by the controller 25, which simultaneously opens the electric valve 12. This booster fan 15 pressurizes external air into the flow guide 13, which is then pumped into the air supply pipe 11 via the electric valve 12. The air supply pipe 11 then delivers the pressurized air to the concave airbag 2, causing it to compress the multiple push plates 3. The push plates 3, in turn, compress the spring bars 4, which in turn compress the curved plates 8. Ultimately, the curved plates 8 and the spring bars 4 simultaneously apply pressure to the side pressure plates 5.

[0037] The side pressure plate 5 drives the L-shaped sleeve 9 to tilt, 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 along the lower surface of the L-shaped frame 7, which in turn drives the two chamfering grinding heads 6 to tilt and press against the two corners of the inner wall of the gear tooth groove. In this way, multiple chamfering grinding heads 6 can move synchronously and in a circular distribution, pressing against the inner corners of multiple gear tooth grooves.

[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 turn off the boost fan 15 and the electric valve 12 to ensure that the multiple chamfering grinding heads 6 are squeezed at the inner wall corners of the multiple tooth grooves of the gear according to the specified extrusion force, thereby realizing 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 to push the circular positioning seat 27 upward. The circular positioning seat 27 drives the gear upward, so that the multiple tooth groove corners of the gear outer wall and the outer wall of the multiple chamfering grinding heads 6 are synchronously extruded and chamfered with a fixed force. At the same time, the gear can also move upward to discharge the material.

[0040] Step 3: During the synchronous grinding and chamfering of the top surface, when the corner of the upper edge of the gear contacts the inner wall of the multiple tooth bends 21, since the cross-sectional area of the upper surface of the tooth bend 21 is larger than the cross-sectional area of its lower surface, the corner of the upper edge of the gear will continuously squeeze the inclined surface of the inner wall of the multiple tooth bends 21, causing the tooth bend 21 to be forced to drive the guide tooth grinding strip 22 backward. The backward movement of the guide tooth grinding strip 22 will cause the upper spring piece 20 to be squeezed and deformed, and at the same time, the tooth bend 21 will also cause the lower spring piece 20 to be squeezed and deformed.

[0041] During this process, the L-shaped frame 7 supports the slide frame 16, which provides support for the two springs 20. The tooth bend bars 21 squeeze the connecting bar 19, guiding it to slide backward along the inner wall of the slide groove 17. Simultaneously, the slide frame 16 guides the slider 18 backward, ensuring that the corners of the upper surface of the gear come into oblique contact with the multiple tooth bend bars 21, achieving adaptive extrusion grinding and chamfering. In this way, the edges of the upper surfaces of the multiple tooth grooves of the gear are synchronously and adaptively chamfered until the gear contacts the upper row of multiple guide tooth grinding bars 22, completing the gear discharge process.

In this technical solution, the electrical control components not mentioned are not shown in the figure because they belong to the existing technology and are not described here.

[0043] The above description is only 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 in the scope of protection of the present invention.
