Description

Technical Field

[0001] This utility model relates to the field of chamfering device technology, specifically a chamfering device for the end face of a flywheel. Background Technology

[0002] Currently, chamfers are typically made at the ends of parts to remove burrs generated during machining and to facilitate assembly. However, existing flywheel chamfering devices generally suffer from problems such as difficulty in positioning and clamping, and inconsistent chamfer sizes and angles, resulting in low efficiency and a low finished product qualification rate during processing.

[0003] A previously published patent (publication number CN209792773U) discloses a flywheel chamfering device. This device causes a sleeve to overfit against a central expansion shaft, expanding the sleeve to fit tightly into the center hole of the flywheel and against the end face of the main shaft flange, thus fixing the flywheel and limiting its axial and radial movement. Simultaneously, the main shaft flange and the flywheel rotate, and a cutting action is performed via a machining component. This invention features a simpler and more compact mechanism, saving space. Furthermore, centering with a central hole ensures consistent flywheel tooth runout, resulting in high uniformity in chamfer size for machined parts. The machining component simultaneously processes the chamfers on both sides of the tooth ends, allowing for individual adjustment of the chamfer dimensions and significantly improving efficiency.

[0004] However, there are some problems with the existing chamfering devices: 1. The spacing of the current chamfering shafts is a fixed size, while the diameter of different flywheel discs is different, so only chamfering grinding rods of different sizes can be replaced, which brings inconvenience to the processing; 2. When replacing the grinding rod, the existing chamfering device disassembles the grinding rod by engaging and disassembling bolts, and then reassembles the bolts to fix it. The disassembly and assembly process is time-consuming and labor-intensive, affecting the efficiency of use. Utility Model Content

[0005] The purpose of this invention is to provide a flywheel disc processing end face chamfering device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including an equipment box, an adjustment assembly disposed at the center and upper and lower sides of the equipment box, an electric rotating shaft disposed at the front end of the adjustment assembly, and a grinding assembly disposed at the front end of the electric rotating shaft;

[0007] The adjustable distance component includes a central slot formed in the center of the equipment box, a first bevel gear is provided on the inner wall of the right end of the central slot, the right end of the first bevel gear is connected to the output end of the motor, and second bevel gears that cooperate with the first bevel gear are provided on the inner walls of the upper and lower sides of the central slot.

[0008] The grinding assembly includes a slot on the front surface of the electric rotating shaft, in which a plate is detachably inserted. The inner walls on the left and right sides of the plate have inner grooves, and an inner plate is movably fitted inside the inner grooves.

[0009] As a further embodiment of this utility model: the adjustable distance component also includes sliding grooves formed on the upper and lower outer sides of the central groove, a screw is installed in the sliding groove, and a sliding plate is fitted on the outer wall of the screw.

[0010] As a further improvement of this utility model: the side wall of the slide groove is provided with a limiting groove, and the side wall of the slide plate is provided with a limiting plate that cooperates with the limiting groove.

[0011] As a further embodiment of this utility model: a first slot is provided on the side wall of the inner groove near the electric rotating shaft, a retaining plate is provided on the side of the inner plate near the first slot, and a retaining groove is provided on the side wall of the slot to cooperate with the retaining plate.

[0012] As a further embodiment of this utility model: a second slot is provided on the side wall of the inner groove away from the electric rotating shaft, and a pressure plate is provided on the side wall of the inner plate near the second slot to cooperate with it. A hydraulic rod is installed on the side wall of the pressure plate near the center of the electric rotating shaft, and a spring is fitted on the outer wall of the hydraulic rod.

[0013] As a further improvement of this utility model, a grinding rod is fitted onto the outer surface of the front end of the insert plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the grinding rod needs to be replaced, the pressure plates on both sides are pressed against each other, causing them to move into the second slot. This compresses the hydraulic rod and spring, generating potential energy. The inner plate then moves the clamping plate into the first slot, causing the clamping plate to disengage from the slot. Pulling the insert plate forward disengages it from the slot, thus completing the individual disassembly of the grinding rod. To replace the grinding rod, the insert plate installed at its rear end is inserted into the slot. The pressure on the pressure plate is released, and the spring releases its potential energy, pushing the pressure plate outward. The inner plate then moves the clamping plate towards the slot and inserts it, thus fixing the insert plate and completing the replacement and fixing of the grinding rod.

[0016] When the spacing of the grinding components needs to be adjusted, the present invention controls the motor to rotate the first bevel gear connected to it, which meshes and drives the upper and lower second bevel gears to rotate simultaneously, driving the screw connected to them to rotate. Under the limitation of the limiting plate embedded in the limiting groove, the meshing drives the sliding plate to move stably towards or away from each other in the sliding groove, so as to efficiently adjust the distance between the upper and lower grinding rods. This makes it convenient to adjust the spacing of the grinding components for the end face chamfering of flywheels of different diameters as needed, thus improving the versatility of the chamfering device.

[0022] To facilitate the solution of the problem, this utility model provides a flywheel disc end face chamfering device. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example 1

[0023] like Figures 1 to 4As shown, this embodiment provides a flywheel disc end face chamfering device, including a device housing 1, a distance adjustment assembly disposed at the center and upper and lower sides of the device housing 1, an electric rotating shaft 3 disposed at the front end of the distance adjustment assembly, and a grinding assembly disposed at the front end of the electric rotating shaft 3. The distance adjustment assembly includes a central groove 201 formed in the center of the device housing 1. A first bevel gear 202 is disposed on the inner wall of the right end of the central groove 201. The right end of the first bevel gear 202 is connected to the output end of a motor 203. Second bevel gears 204 that cooperate with the first bevel gear 202 are disposed on the inner walls of the upper and lower sides of the central groove 201. When the screw 206 rotates, under the limitation of the limiting plate 209 embedded in the limiting groove 208, it meshes and drives the sliding plate 207 to slide in the sliding groove 205. The stable movement of the inner and outer grinding rods 412 allows for efficient adjustment of the distance between them. This facilitates the adjustment of the grinding assembly spacing by chamfering the end faces of flywheels of different diameters as needed. The grinding assembly includes a slot 401 on the front surface of the electric rotating shaft 3. A plate 402 is detachably inserted into the slot 401. Inner grooves 403 are formed on the inner walls of the left and right sides of the plate 402. An inner plate 404 is movably embedded inside the inner grooves 403. The pressure of the pressure plate 409 causes the spring 411 to release potential energy and push the pressure plate 409 outward. The inner plate 404 drives the clamping plate 406 to move towards the clamping groove 407 and insert it, thus fixing the plate 402 and completing the replacement and fixing of the grinding rod 412. Example 2

[0024] In addition to all the technical features in Embodiment 1, this embodiment also includes: the distance adjustment component further includes sliding grooves 205 formed on the upper and lower outer sides of the central groove 201, a screw 206 is installed in the sliding groove 205, and a sliding plate 207 is fitted on the outer wall of the screw 206. The sliding plate 207 moves stably towards or away from each other in the sliding groove 205, so as to efficiently adjust the distance between the upper and lower grinding rods 412.

[0025] Furthermore, the side wall of the slide groove 205 is provided with a limiting groove 208, and the side wall of the slide plate 207 is provided with a limiting plate 209 that cooperates with the limiting groove 208. Under the limiting position of the limiting plate 209 embedded in the limiting groove 208, the sliding plate 207 is engaged and driven to move stably towards or away from each other in the slide groove 205, and the spacing is stably adjusted.

[0026] Furthermore, the inner groove 403 has a first slot 405 on one side wall near the electric rotating shaft 3, and a retaining plate 406 is provided on one end of the inner plate 404 near the first slot 405. The slot 401 has a retaining groove 407 on its side wall that cooperates with the retaining plate 406. The retaining plate 406 moves toward the retaining groove 407 and is inserted to fix the insert plate 402.

[0027] Furthermore, a second slot 408 is provided on the side wall of the inner groove 403 away from the electric rotating shaft 3. A pressure plate 409 is provided on the side wall of the inner plate 404 near the second slot 408. A hydraulic rod 410 is installed on the side wall of the pressure plate 409 near the center of the electric rotating shaft 3. A spring 411 is fitted on the outer wall of the hydraulic rod 410. The spring 411 releases potential energy to push the pressure plate 409 outward. The inner plate 404 drives the clamping plate 406 to move towards the clamping slot 407 and insert it, thereby completing the fixing of the insert plate 402 and thus completing the replacement and fixing of the grinding rod 412.

[0028] Furthermore, a grinding rod 412 is fitted onto the outer surface of the front end of the insert plate 402, and the grinding rod 412 can be easily disassembled and replaced by disassembling and assembling the insert plate 402.

[0029] Working principle: When the grinding rod 412 needs to be replaced, press the pressure plates 409 on both sides towards each other to move them into the second slot 408. This compresses the hydraulic rod 410 and spring 411, generating potential energy. This energy, through the inner plate 404, drives the clamping plate 406 towards the first slot 405, causing the clamping plate 406 to disengage from the slot 407. Pull the insert plate 402 forward to disengage it from the slot 401, thus completing the individual disassembly of the grinding rod 412. To replace the required grinding rod 412, insert the insert plate 402 at its rear end into the slot 401. Release the pressure on the pressure plate 409. The spring 411 releases its potential energy, pushing the pressure plate 409 outward. This, through the inner plate 404, drives the clamping plate 406 towards the slot 407. By moving and inserting, the insert plate 402 can be fixed, thereby completing the replacement and fixing of the grinding rod 412. When it is necessary to adjust the spacing of the grinding components, the control motor 203 is turned to drive the first bevel gear 202 connected to it to rotate, which in turn drives the upper and lower second bevel gears 204 to rotate simultaneously, driving the screw 206 connected to it to rotate. Under the limitation of the limiting plate 209 embedded in the limiting groove 208, the meshing drives the sliding plate 207 to move stably towards or away from each other in the sliding groove 205, which can efficiently adjust the distance between the upper and lower grinding rods 412. This makes it convenient to adjust the spacing of the grinding components for the end face chamfering of flywheels of different diameters as needed, improving the versatility of the chamfering device.
