Description

Technical Field

[0001] This utility model relates to the field of gear grinding technology, and in particular to a high-efficiency grinding device for gear processing. Background Technology

[0002] When gears are manufactured, burrs are formed on their edges, which need to be removed. Therefore, an existing gear burr removal device (publication number CN223277693U) places the gear to be removed on a rotating table, with the inner ring of the gear engaged with a fixed block. A pressure block is lifted, and an adjusting rod is aligned with an adjusting groove. The pressure block is rotated to move it downwards, using a first rubber ring to contact the gear and lower it. The gear is then moved to the corresponding position on the fixed block according to the size of the inner ring and fixed. After fixing, a first motor drives the rotating table to rotate, causing the gear to rotate. The control panel then controls an electric push rod to move a moving block, moving the grinding assembly. A second motor in the grinding assembly drives a lead screw to adjust the position of the grinding head, bringing it into contact with the top surface of the gear for grinding. After the top surface of the gear is ground, the electric push rod drives the moving block to move the grinding assembly, moving the grinding head away from the gear. The second motor drives the lead screw to rotate, positioning the grinding head below the gear. The electric push rod then drives the moving block to bring the grinding head closer to the gear, adjusting its position to contact the bottom surface of the gear for further grinding.

[0003] However, the existing technology's fixing logic is based on the existence of an inner ring for the gear, and positioning is achieved by cooperating with the inner ring through structures such as fixing blocks and chucks. Solid gears do not have an inner ring hole and cannot be matched with existing fixing structures at all, resulting in solid gears being unable to be fixed and thus unable to be polished. In other words, although the existing technology can be adapted to some hollow gears, it still has obvious shortcomings in terms of compatibility, fixing stability, and polishing comprehensiveness of hollow gears due to the limitations of the fixing structure design. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a high-efficiency grinding device for gear processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency grinding device for gear processing, comprising a grinding table, a turntable rotatably connected to the table surface, a cross groove being formed on the upper surface of the turntable, a sleeve being installed at the center of the cross groove, and a clamping rod that swings up and down being hinged in each direction of the groove on the top edge of the outer wall of the sleeve, a mounting frame being fixedly installed on the outer wall of the sleeve, a lifting ring coaxially distributed with the sleeve being sleeved on the mounting frame, and an electric screw that is parallel to the central axis of the sleeve and threaded through the lifting ring from top to bottom being rotatably connected to the mounting frame, and a connecting arm that swings up and down being hinged below each groove of the cross groove on the outer wall of the lifting ring, the swinging end of the connecting arm being hinged to the surface of the clamping rod in the groove of the cross groove directly above.

[0006] Preferably, a coaxially distributed spur gear ring is fixedly installed on the bottom edge of the turntable, and a spur gear driven by a motor and meshing with the spur gear ring is installed on the bottom surface of the grinding table.

[0007] Preferably, a connecting frame is fixedly installed on the bottom surface of the turntable, and an electric telescopic rod that extends upward and is coaxially distributed with the sleeve is fixedly installed on the bottom surface of the connecting frame. The telescopic end of the electric telescopic rod is connected to the top end of the sleeve.

[0008] Preferably, a set of ball bearing seats is embedded in the upper surface of the turntable between two adjacent cross grooves. The outer shell of the ball bearing seat is embedded in the upper surface of the turntable, and the ball bearing portion of the ball bearing seat is used to contact the end face of the gear.

[0009] Preferably, the grinding table surface is connected to vertically arranged linear modules on both the left and right sides of the turntable, and the slider part of the linear module moves vertically, and a horizontally arranged electric push rod is fixedly installed on the side of the slider of the linear module.

[0010] Preferably, the telescopic end of the electric push rod points to the central axis of the turntable, and a grinding tool assembly for grinding the gear surface is fixedly installed on the telescopic end of the electric push rod.

[0011] Preferably, the linear module revolves around the center of the turntable, and arc-shaped bevel racks with the same center as the turntable are fixedly installed on both the left and right sides of the grinding table surface. The linear module surface is equipped with bevel gears that are driven by a motor and mesh with adjacent arc-shaped bevel racks.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the swing end of the clamping rod adopts an L-shaped design. The straight section can be used to abut the inner arc surface of the hollow toothed ring, and the transverse section can be used to hold the outer side of the solid gear. It can adapt to the clamping requirements of two types of workpieces without changing the clamping jaws, reducing tooling change time and improving processing efficiency. The lifting ring is driven to rise and fall by the electric screw, which drives the connecting arm to push the clamping rod to swing. The distribution diameter of the swing end of the clamping rod can be flexibly adjusted to adapt to gears or toothed rings of the same type but different specifications, thus improving the applicability of the device.

[0013] 2. In this utility model, when the grinder revolves around the center of the gear, the contact angle between the grinder and the gear tooth surface changes dynamically with the revolution. In conjunction with the rotation of the turntable, it can completely cover every tooth of the gear tooth surface. Except for the area temporarily blocked by the clamping rod, there is no need to adjust the initial position of the grinder multiple times, reducing process redundancy. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] like Figures 1-4As shown, a high-efficiency grinding device for gear processing includes a grinding table 1. A turntable 8 is rotatably connected to the table surface of the grinding table 1. Gears are placed flat on the turntable 8 and coaxially distributed. A coaxially distributed spur gear ring 13 is fixedly installed on the bottom edge of the turntable 8. A spur gear 12, driven by a motor and meshing with the spur gear ring 13, is installed on the bottom surface of the grinding table 1. In actual use, by driving the spur gear 12 to rotate through the motor embedded in the bottom of the grinding table 1, the spur gear ring 13 drives the turntable 8 to rotate. That is, when the gear is fixed on the surface of the turntable 8, the rotation of the turntable 8 drives the clamped gear to rotate synchronously, thereby adjusting the grinding area of ​​the gear. A cross groove 10 is opened on the upper surface of the turntable 8. A sleeve 17 is installed at the center of the cross groove 10. A swinging clamping rod 11 is hinged to the top edge of the outer wall of the sleeve 17 in each direction of the groove of the cross groove 10. A mounting bracket is fixedly installed on the outer wall of the sleeve 17. 19. A lifting ring 16, coaxially distributed with the sleeve, is fitted on the mounting frame 19. An electric screw 2, parallel to the central axis of the sleeve and threaded through the lifting ring 16 from top to bottom, is rotatably connected to the mounting frame 19. A connecting arm 18, which swings up and down, is hinged to the outer wall of the lifting ring 16 below each slot of the cross groove 10. The swinging end of the connecting arm 18 is hinged to the surface of the clamping rod 11 in the slot of the cross groove 10 directly above. In actual use, a motor is installed on the mounting frame 19 to drive the electric screw 2 to rotate. Because the lifting ring 16, threadedly connected to the electric screw 2, is fitted on the mounting frame 19, the rotation of the electric screw 2 only causes the lifting ring 16 to rise and fall along the surface of the mounting frame 19. When the lifting ring 16 rises, the clamping rod 11 swings upward under the pushing action of the connecting arms 18. During the upward swing, the diameter of the swinging ends of the clamping rods 11 can be adjusted. Figure 4 As shown, the swing end of the clamping rod 11 is L-shaped. Therefore, when the gear is hollow, that is, when it is a gear ring, the swing end of the clamping rod 11 abuts against the inner arc surface of the gear ring. When the object being processed is a solid gear, the L-shaped part of the swing end of the clamping rod 11 clamps the outer side of the gear.

[0019] A connecting frame 14 is fixedly installed on the bottom surface of the turntable 8. An electric telescopic rod 15 that extends upward and is coaxially distributed with the sleeve is fixedly installed on the bottom surface of the connecting frame 14. The telescopic end of the electric telescopic rod 15 is connected to the top position inside the sleeve. When the clamping rod 11 swings upward, in order to prevent the horizontal part of the clamping rod 11 from exceeding the groove of the cross groove 10 and causing the inner arc surface or outer side of the size placed on the turntable 8 to not be able to contact the swinging end of the clamping rod 11, the sleeve is lowered by retracting the electric telescopic rod 15. This allows the clamping rod 11 to be lowered as a whole until only the swinging end of the clamping rod 11 is located on the upper surface of the turntable 8.

[0020] A set of ball bearing seats 9 is embedded in the upper surface of the turntable 8 between two adjacent cross grooves 10. The outer shell of the ball bearing seat 9 is embedded in the upper surface of the turntable 8. The ball bearing part of the ball bearing seat 9 is used to contact the end face of the gear. The ball bearing seat 9 facilitates the release of the clamping rod 11 after the surface treatment of the gear and the contact part with the clamping rod 11 are polished. The operator rotates the gear by the cooperation of the ball bearings and uses the clamping rod 11 to clamp the area of ​​the gear surface that has been polished, so that the area that was previously in contact with the clamping rod 11 is exposed, which is convenient for secondary polishing of the area.

[0021] The grinding table 1 has vertically arranged linear modules 4 inserted on both sides of the turntable 8. The slider part of the linear module 4 moves vertically, and a horizontally arranged electric push rod 5 is fixedly installed on the side of the slider of the linear module 4. The extension end of the electric push rod 5 points to the central axis of the turntable 8, and a grinding device assembly 6 for grinding the gear surface is fixedly installed on the extension end of the electric push rod 5. The linear module 4 revolves around the center of the turntable 8. Arc-shaped bevel racks 3 with the same center as the turntable 8 are fixedly installed on both sides of the grinding table 1. The surface of the linear module 4 is equipped with cones that are driven by a motor and mesh with the adjacent arc-shaped bevel racks 3. In actual use, gear 7 is driven to rotate by a motor installed on the linear module 4. The meshing connection between the bevel gear 7 and the arc-shaped bevel rack 3 enables the gear to roll on the arc-shaped bevel rack 3 while revolving around the center of the turntable 8. This, in turn, enables the linear module 4 to revolve around the center of the turntable 8. During the revolution, the electric push rod 5 installed on the linear module 4, in conjunction with the rotation of the turntable 8, can contact the gear tooth surface, except for the area in contact with the clamping rod 11. Furthermore, by extending the electric push rod 5, the grinder can approach the gear tooth surface. By coordinating with the linear module 4 to drive the electric push rod 5 to rise and fall, the grinding of the gear tooth surface can be completed.

[0022] The method of using this utility model is as follows: Place the gear or gear ring to be processed flat on the turntable 8, ensuring that it is coaxially distributed with the turntable 8; the ball bearing portion of the ball bearing seat 9 on the turntable 8 contacts the end face of the gear or gear ring to reduce subsequent rotational resistance; start the motor on the mounting bracket 19 to drive the electric lead screw 2 to rotate and raise the lifting ring 16, and push the clamping rod 11 in the cross groove 10 to swing upward through the connecting arm 18, adjusting the distribution diameter of the swinging end of the clamping rod 11; if it is a hollow gear ring: the swinging end of the clamping rod 11 abuts against the inner arc surface of the gear ring, and the internal support is fixed by the synchronous abutment of the multi-directional clamping rod 11; if it is a solid gear: the L-shaped structure of the swinging end of the clamping rod 11 fastens the outer side of the gear, and the external clamping is fixed by the synchronous clamping of the multi-directional clamping rod 11.

[0023] Based on the tooth surface height of the gear or gear ring, activate the linear modules 4 on both sides of the turntable 8, driving the slider to raise and lower the electric push rod 5 and the grinder assembly 6 to the initial height adapted to the tooth surface; then activate the electric push rod 5 to bring the grinder assembly 6 closer to the tooth surface. Activate the motor on the linear module 4 to drive the bevel gear 7 to rotate. Utilize the meshing of the bevel gear 7 with the arc-shaped bevel rack 3 to make the linear module 4 revolve around the center of the turntable 8, thereby driving the grinder assembly 6 to revolve synchronously.

[0024] During the revolution, the electric push rod 5 makes real-time fine adjustments according to the tooth surface spacing to ensure that the grinder maintains stable contact pressure with the tooth surface; The linear module 4 synchronously drives the electric push rod 5 to rise and fall, covering the entire tooth surface height range of the gear or gear ring; The turntable 8 rotates continuously, cooperating with the grinder's revolution to achieve full coverage grinding of the tooth surface except for the contact area of ​​the clamping rod 11.

[0025] Grinding of the contact area of ​​clamping rod 11: After the non-clamping area is ground, control the electric lead screw 2 to rotate in the opposite direction, so that the lifting ring 16 descends and the clamping rod 11 releases the gear or toothed ring; the operator uses the rolling of the balls in the ball seat 9 to manually rotate the gear or toothed ring to expose the area that was originally in contact with the clamping rod 11; restart the clamping step to fix the gear or toothed ring, repeat the grinding process, and complete the grinding of the entire tooth surface.

[0026] The wiring diagrams of the motor, linear module 4, electric push rod 5, electric telescopic rod 15, and grinder assembly 6 in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the motor, linear module 4, electric push rod 5, electric telescopic rod 15, and grinder assembly 6 will not be explained in detail.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
