Description

Technical Field

[0001] This utility model relates to the field of gear processing equipment technology, and in particular to an automatic deburring device for micro-sized gears. Background Technology

[0002] A gear is a mechanical component that transmits motion and power through continuous meshing of gears on its rim. Gears have been used in transmission for a long time. In the late 19th century, with the emergence of the generating gear cutting method and specialized machine tools and cutting tools using this principle, the smoothness of gear operation became increasingly important as production developed.

[0003] The existing technology, CN2021216767377, is a deburring equipment for shaft meshing machines. The existing deburring equipment for gears is only suitable for processing large and large-sized gears. However, it cannot be used for some micro and small gears. Because the meshing teeth of small gears are relatively small, the existing deburring equipment cannot be used after processing.

[0004] Therefore, it is necessary to design a micro-sized automatic deburring device for gears to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic deburring device for micro-sized gears to overcome the aforementioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A miniature automatic deburring device for gears includes a frame, a mounting plate on the frame, and a slide rail on the mounting plate. The device further includes a coarse deburring mechanism, a fine deburring mechanism, and a gear fixing device between the coarse and fine deburring mechanisms, each mounted on the slide rail via a slider. The fine and coarse deburring mechanisms are respectively located on opposite sides of the slide rail. The coarse deburring mechanism includes a coarse deburring drive base plate, a drive unit for moving the coarse deburring drive base plate along the slide rail, and a gear fixing device mounted on the coarse deburring drive base plate. The base plate includes a mounting plate, a ball screw assembly on the mounting plate, an adjusting plate driven to move up and down by the ball screw, a drive cylinder mounted on the adjusting plate, a mounting base driven to move up and down by the drive cylinder, a coarse fixing seat mounted to the mounting base via a shaft, a floating mechanism mounted on the coarse fixing seat, and a deburring block mounted on the floating mechanism. The gear fixing device includes a rotating motor fixed to the bottom of the mounting plate, a clamping cylinder driven to rotate by the rotating motor, a clamping block driven to clamp or loosen by the clamping cylinder, and a tooling placed at the center of the clamping cylinder.

[0008] Preferably, the floating mechanism includes a rotating shaft rotatably mounted in the coarse fixed seat, a floating block fixed on the rotating shaft, and springs respectively disposed at both ends of the floating block; one end of the spring at both ends of the floating block is fixed on the floating block, and the other end is fixed on the coarse fixed seat.

[0009] Preferably, the fine deburring mechanism includes a fine mounting base plate, a drive unit that drives the fine mounting base plate to move along the slide rail, a fine mounting upright plate mounted on the fine mounting base plate, a fine ball screw assembly disposed on the fine mounting upright plate, a fine drive plate that moves up and down driven by the fine ball screw assembly, a fine drive cylinder mounted on the fine drive plate, a fine mounting block that moves up and down driven by the fine drive cylinder, a fine mounting base that is connected and fixed to the fine mounting block by a connecting rod, a motor mounted on the fine mounting base by a motor mounting bracket, and a deburring wheel driven by the motor.

[0010] The beneficial effects of this utility model are: by setting a coarse deburring mechanism and a fine deburring mechanism to be used together, small gears can be deburred. At the same time, by setting a floating mechanism, the floating mechanism can be used in conjunction with the deburring block, and can also be used with gears of different angles to deburr. The angle can be offset by the springs at both ends, so it is suitable for deburring gears with gears of different angles, which greatly improves efficiency. Attached Figure Description

[0015] Reference Figures 1 to 3 A miniature automatic deburring device for gears includes a machine frame 1, a mounting plate 2 set on the machine frame, a slide rail 3 set on the mounting plate, a coarse deburring mechanism 4 and a fine deburring mechanism 5 respectively set on the slide rail by a slider, and a gear fixing device 6 between the coarse deburring mechanism and the fine deburring mechanism.

[0016] The fine deburring mechanism and the coarse deburring mechanism are respectively disposed on both sides of the slide rail. The coarse deburring mechanism 4 includes a coarse deburring drive base plate 41, a drive unit 42 that drives the coarse deburring drive base plate to move along the slide rail, a mounting plate 43 mounted on the coarse deburring drive base plate, a ball screw assembly 44 disposed on the mounting plate, an adjusting plate 45 that moves up and down driven by the ball screw, a drive cylinder 46 mounted on the adjusting plate, a mounting seat 47 that moves up and down driven by the drive cylinder, a coarse fixing seat 49 mounted to the mounting seat via a shaft 48, and a mounting base 49 mounted on the slide rail. The floating mechanism 411 on the coarse fixed seat and the deburring block 412 installed on the floating mechanism; the entire coarse deburring drive base plate 41 is driven by the drive unit to move along the slide rail, approaching or moving away from the gear fixing device 6. If deburring is required, it is moved close to the gear fixing device 6. The height of the entire drive cylinder 46 and the height of the deburring block 412 are adjusted manually by adjusting the ball screw assembly 44. After adjusting to the appropriate position corresponding to the gear model, the deburring block 412 is moved up and down by the drive cylinder 46 to deburr the gear teeth.

[0017] The floating mechanism 411 includes a rotating shaft 4111 rotatably mounted in the coarse fixed seat, a floating block 4112 fixed on the rotating shaft, and springs 4113 respectively disposed at both ends of the floating block 4112;

[0018] One end of the spring 4113 at both ends of the floating block 4112 is fixed to the floating block, and the other end is fixed to the coarse fixed seat. The rotating shaft 4111 rotates around the center. The floating block 4112 is fixed on the rotating shaft 4111, so the floating block can rotate synchronously. In order to limit the rotation angle at both ends of the floating block, the spring is used to limit the rotation angle of the floating block. The deburring block 412 is installed on the floating block by a rotating motor. Therefore, the deburring block 412 can rotate around the axis of the rotating shaft 4111. Since the meshing angle of the gear teeth is different, some gear teeth are set at an angle. Each tooth needs to be deburred. The rotating motor drives the deburring block 412 to rotate, and then drives it to move up and down through the drive cylinder. The deburring block 412 is inserted into the meshing teeth of the gear to deburr the teeth. The synchronous gear fixing device drives the gear to rotate and deburrs the teeth of the gear one by one. If the meshing angle is set at an angle, the deburring block will float and tilt in coordination with the floating mechanism after it is inserted into the meshing teeth, so as to adapt to different gears for deburring.

[0019] The fine deburring mechanism 5 includes a fine mounting base plate 51, a drive unit that drives the fine mounting base plate to move along the slide rail, a fine mounting upright plate 52 mounted on the fine mounting base plate 51, a fine ball screw assembly 53 disposed on the fine mounting upright plate 52, a fine drive plate 54 that moves up and down driven by the fine ball screw assembly, a fine drive cylinder 55 mounted on the fine drive plate, a fine mounting block 56 that moves up and down driven by the fine drive cylinder, a fine mounting base 57 that is connected and fixed to the fine mounting block by a connecting rod, and a motor 58 mounted on the fine mounting base by a motor mounting bracket. And the deburring wheel 59 driven by the motor; the drive unit drives the precision mounting base plate 51 to move closer to or away from the gear fixing device 6, thereby driving the entire structure. After the coarse deburring mechanism has finished processing, the deburring wheel 59 is driven to move closer to the gear fixed on the gear fixing device 6. The height position of the deburring wheel 59 is adjusted up and down by manually adjusting the precision ball screw assembly 53 to a suitable position for gear processing. Then, the precision drive cylinder drives the deburring wheel 59 to move up and down to perform deburring and polishing treatment on the outer periphery, meshing teeth and local internal gaps of the gear.

[0020] The gear fixing device 6 includes a rotating motor 61 fixed to the bottom of the mounting plate, a clamping cylinder 62 driven to rotate by the rotating motor, a clamping block 63 driven to clamp or loosen by the clamping cylinder, and a tooling 64 placed at the center of the clamping cylinder.

[0021] The gear to be processed is placed on the tooling 64, and the clamping block 63 is driven by the clamping cylinder to clamp it, thereby fixing the gear. Specifically, the clamping block is placed inside the gear shaft and fixed by internal support, so as not to affect the deburring of the gear's external meshing teeth.

[0022] In this embodiment, the gear to be processed is placed on the fixture, and the clamping block 63 is driven by the clamping cylinder to clamp it, thereby fixing the gear. First, the height of the entire drive cylinder 46 and the height of the deburring block 412 are adjusted manually by the ball screw assembly 44 to the appropriate position for the corresponding gear model. Then, the height of the deburring wheel 59 is adjusted manually by the fine ball screw assembly 53 to the appropriate position for gear processing. The drive unit drives the entire coarse deburring drive base plate 41 to move along the slide rail and approach the gear fixing device 6, i.e., the gear to be processed. The deburring block 412 is placed above the fixture. The rotating motor drives the deburring block 412 to rotate, and then the drive cylinder drives it to move up and down. The deburring block 412 engages with the gear teeth to deburr the teeth. Simultaneously, the gear fixing device drives the gear to rotate. The deburring mechanism deburrs each tooth of the gear. If the tooth angle is inclined, the deburring block will float and tilt after being inserted into the tooth, thus adapting to different gears for deburring. The synchronous rotating motor 61 rotates, rotating a certain angle each time. After stopping, the deburring block is driven to move up and down to deburr the corresponding tooth. This process is repeated until the deburring of the gear teeth is completed. Then, the mechanism is reset and driven by the drive unit to move the precision mounting base plate 51 close to the gear fixing device 6, thus driving the entire structure. After the coarse deburring mechanism has finished, the deburring wheel 59 is driven to move close to the gear fixed on the gear fixing device 6. The motor 58 drives the deburring wheel 59 to rotate, and then the precision drive cylinder drives the deburring wheel 59 to move up and down to deburr and polish the outer periphery, teeth, and local internal gaps of the gear.

[0023] The advantages of this invention are that by combining a coarse deburring mechanism and a fine deburring mechanism, small gears can be deburred. At the same time, by setting a floating mechanism, which works in conjunction with the deburring block and with gears of different angles, deburring can also be performed. The floating mechanism can shift its angle with the springs at both ends, thus being suitable for deburring gears with gears of different angles, which greatly improves efficiency.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
