Description

Technical Field

[0001] This utility model relates to the field of gear manufacturing technology, specifically a burr removal device for automotive gear manufacturing. Background Technology

[0002] Automotive gears are key components in the automotive power transmission system, playing a crucial role. A gear is a disc-shaped mechanical element with teeth, typically involute teeth, that transmits torque through friction between the tooth surfaces, thus transmitting power. In automobiles, gears are widely used in transmissions, differential gearboxes, transfer cases, power steering systems, engine timing systems, turbocharger and supercharger systems, fuel injection systems, water pumps, variable valve timing systems, and starter motors. They help to smoothly change the speed and torque between the engine and wheels, achieving efficient power transmission, while also improving the vehicle's handling performance and fuel economy.

[0003] Typically, automotive gears are machined using specialized gear grinding machines. However, during the grinding process, tiny burrs often form on both sides of the gear teeth. If these burrs are not removed, they will affect the normal operation and lifespan of the gear. Therefore, workers usually use handheld grinders to meticulously remove these burrs. During the grinding process, the gear workpiece is first placed in a special fixture to ensure it remains stable during grinding. Once one side of the gear is ground, the worker releases the fixture and adjusts the gear's position to perform the same grinding on the other side. This process needs to be repeated until all the burrs on both sides of the gear are completely removed. Although this method effectively removes burrs, it is relatively slow. Utility Model Content

[0004] The purpose of this invention is to provide a burr removal device for automotive gear production, so as to solve the problem of slow burr removal speed in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a burr removal device for automotive gear production, comprising a worktable, on which an equipment housing is fixedly installed, a movable slide groove is provided on the equipment housing, and a grinding mechanism is provided at the movable slide groove. The grinding mechanism includes an adjusting screw rotatably installed inside the equipment housing, a screw nut is provided on the adjusting screw, a lifting beam is fixedly installed on the screw nut, a retainer is fixedly installed on the lifting beam, telescopic rods are slidably installed on both sides of the retainer, springs are sleeved on the telescopic rods, a grinding wheel is fixedly installed at the end of the springs, and a positioning mechanism is installed on the equipment housing.

[0006] Preferably, a helical gear disk is fixedly installed at the upper end of the adjusting screw, a helical gear is rotatably installed on one side of the helical gear disk, an adjusting shaft is fixedly installed on the helical gear, and a knob is fixedly installed at the end of the adjusting shaft.

[0007] Preferably, the retainer has a movable hole, and the telescopic rod is slidably mounted on the retainer through the movable hole.

[0008] Preferably, the lifting beam extends out of the equipment housing through a movable slide groove, the helical gear is rotatably mounted on one side of the helical gear disk through an adjusting shaft, and the helical gear disk meshes with the helical gear, and the grinding wheel is movably mounted in the retainer through a telescopic rod.

[0009] Preferably, the positioning mechanism includes a drive motor fixedly mounted on the side wall of the equipment housing and a drive shaft rotatably mounted on the equipment housing. A reduction gear and a limit seat are fixedly mounted on the drive shaft, and a limit nut is rotatably mounted on the drive shaft. A drive gear is fixedly mounted at the output end of the drive motor, and a gear workpiece is connected to the drive shaft.

[0010] Preferably, the device housing is provided with a bearing, and the drive shaft is rotatably mounted on the device housing via the bearing.

[0011] Preferably, the drive gear is rotatably mounted below the reduction gear via a drive motor, and the drive gear meshes with the reduction gear. The gear workpiece is restricted to one side of the limit seat by a limit nut.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, after the drive motor is started, it drives the gear to rotate. Subsequently, the rotation of the drive gear will cause the reduction gear to rotate, which in turn drives the drive shaft to rotate. The rotation of the drive shaft will then cause the gear workpiece to rotate. During the rotation of the gear workpiece, the spring provides forward power to the telescopic rod, enabling the grinding wheel to contact the two side edges of the gear workpiece, thereby achieving rapid grinding of the burrs on both sides of the gear workpiece.

[0014] 2. In this application, the adjustment shaft can be rotated by turning a knob. The rotation of the adjustment shaft drives the rotation of the helical gear, which in turn causes the helical gear disc to rotate. The rotation of the helical gear disc drives the rotation of the adjustment screw, which in turn causes the screw nut to move vertically. The vertical movement of the screw nut causes the lifting beam to move up and down, which in turn causes the grinding wheel in the cage to move up and down accordingly. This series of actions allows the grinding wheel to be positioned on the edge of gear workpieces of different diameters, thus facilitating precise grinding of workpieces of various sizes.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a burr removal device for automotive gear production, including a workbench 4, an equipment housing 2 fixedly installed on the workbench 4, a movable slide groove 3 opened on the equipment housing 2, a grinding mechanism 6 provided at the movable slide groove 3, and a positioning mechanism 5 installed on the equipment housing 2. Through the cooperation of the grinding mechanism 6 and the positioning mechanism 5, the burrs on both sides of the gear workpiece 1 can be quickly ground.

[0022] like Figure 2 and Figure 3As shown, the positioning mechanism 5 includes a drive motor 501 fixedly installed on the side wall of the equipment housing 2 and a drive shaft 503 rotatably installed on the equipment housing 2. A reduction gear 502 and a limit seat 504 are fixedly installed on the drive shaft 503. A limit nut 505 is rotatably installed on the drive shaft 503. A drive gear 506 is fixedly installed at the output end of the drive motor 501. A gear workpiece 1 is connected to the drive shaft 503. A bearing is provided on the equipment housing 2. The drive shaft 503 is rotatably installed on the equipment housing 2 through the bearing.

[0023] Specifically, when the drive motor 501 is started, it begins to rotate and drives the connected drive gear 506. As the drive gear 506 rotates, it further drives the reduction gear 502 to rotate. During its rotation, the reduction gear 502 transmits power to the drive shaft 503, causing it to rotate as well. The rotation of the drive shaft 503 directly affects the gear workpiece 1, causing it to rotate as well. During the rotation of the gear workpiece 1, the spring 606 provides forward power to the telescopic rod 605. Under the action of the spring 606, the telescopic rod 605 moves forward, allowing the grinding wheel 607 to closely contact the two edges of the gear workpiece 1. In this way, the grinding wheel 607 can efficiently and quickly grind the burrs on both sides of the gear workpiece 1, ensuring smooth edges and achieving the required machining accuracy.

[0024] like Figure 2 and Figure 4 As shown, the grinding mechanism 6 includes an adjusting screw 601 rotatably mounted inside the equipment housing 2, a screw nut 602 on the adjusting screw 601, a lifting beam 603 fixedly mounted on the screw nut 602, a retainer 604 fixedly mounted on the lifting beam 603, telescopic rods 605 slidably mounted on both sides of the retainer 604, a spring 606 sleeved on the telescopic rod 605, a grinding wheel 607 fixedly mounted at the end of the spring 606, a movable hole on the retainer 604, the telescopic rod 605 slidably mounted on the retainer 604 through the movable hole, the lifting beam 603 extending out of the equipment housing 2 through the movable groove 3, a helical gear 609 rotatably mounted on one side of the helical gear disk 608 through the adjusting shaft 610, and the helical gear disk 608 meshing with the helical gear 609, and the grinding wheel 607 movably mounted inside the retainer 604 through the telescopic rod 605.

[0025] Specifically, the rotation of knob 611 is transmitted to adjusting shaft 610, causing it to rotate. The rotation of adjusting shaft 610 is then transmitted to helical gear 609, causing it to rotate as well. The rotation of helical gear 609 is then transmitted to helical gear disc 608, causing it to rotate. The rotation of helical gear disc 608 drives adjusting screw 601 to rotate. The rotation of adjusting screw 601 causes screw nut 602 to move vertically. The vertical movement of screw nut 602 directly affects the lifting action of lifting beam 603. The lifting action of lifting beam 603 further affects the lifting action of grinding wheel 607 within cage 604. Ultimately, the lifting action of grinding wheel 607 allows it to precisely engage at the edge of gear workpieces 1 of different diameters, facilitating precise grinding operations on workpieces of various diameters.

[0026] Working principle: First, connect the gear workpiece 1 to the drive shaft 503. After connecting the gear workpiece 1 to the drive shaft 503, tighten the limit nut 505 to fix the gear workpiece 1 at the limit seat 504. Then, rotate the knob 611. Rotating the knob 611 will drive the adjusting shaft 610 to rotate. The rotation of the adjusting shaft 610 will drive the helical gear 609 to rotate. The rotation of the helical gear 609 will drive the helical gear disc 608 to rotate. The rotation of the helical gear disc 608 will drive the adjusting screw 601 to rotate. The rotation of the adjusting screw 601 will drive the screw nut 602 to move up and down. When the screw nut 602 moves up and down, it will drive the lifting beam 603 to rise and fall. When the lifting beam 603 rises and falls, it will... The grinding wheel 607 inside the retainer 604 is raised and lowered, allowing the grinding wheel 607 to be engaged at the edge of gear workpieces 1 of different diameters. After the grinding wheel 607 is engaged at the edge of the gear workpiece 1, the drive motor 501 can be started. After the drive motor 501 is started, it will drive the drive gear 506 to rotate. After the drive gear 506 rotates, it will drive the reduction gear 502 to rotate. After the reduction gear 502 rotates, it will drive the drive shaft 503 to rotate. After the drive shaft 503 rotates, it will drive the gear workpiece 1 to rotate. During the rotation of the gear workpiece 1, the spring 606 will provide forward power to the telescopic rod 605, causing the grinding wheel 607 to contact the edges of both sides of the gear workpiece 1, thereby quickly grinding the burrs on both sides of the gear workpiece 1.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
