Description
Technical Field
[0001] The utility model belongs to the technical field of gear grinding machines and relates to a compact gear grinding machine with high stability. Background Art
[0002] Gear grinding machine is a gear processing machine tool that uses grinding wheel as a grinding tool to process cylindrical gears or certain gears (helical gears, bevel gears, etc.) and tool tooth surfaces. It is mainly used to eliminate deformation after heat treatment and improve gear accuracy. During the processing of gears, a series of processing processes such as rough turning, fine turning, shaving, hobbing, chamfering, grinding, chamfering, cleaning, etc. are required. Gear grinding machine is mainly used to eliminate deformation after heat treatment and improve gear accuracy, so that the accuracy of the teeth after grinding is higher.
[0003] Existing gear grinding machines are generally large machines, which are equipped with a clamping structure and a grinding structure that can be adjusted at multiple angles and moved in multiple directions. In addition, they are also equipped with a variety of sensors to ensure the accuracy of the gears after grinding. Therefore, the gear grinding machine is large in size and high in cost.
[0004] Based on this, we designed a compact gear grinding machine with high stability. Utility Model Content
[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose a compact gear grinding machine with high stability. The technical problem to be solved by the device is: how to simplify the structure of the gear grinding machine, reduce the size of the equipment and reduce the cost of the equipment.
[0006] The purpose of the utility model can be achieved through the following technical solutions:
[0007] A compact gear grinding machine with high stability comprises a workbench, wherein a central column for placing a gear is rotatably arranged on the workbench, and a through hole is opened on the top of the workbench, a U-shaped plate is fixed in the through hole, and a screw motor is installed on the inner side of the U-shaped plate, the screw motor is vertically arranged, a mounting plate is fixed to the side end of the screw motor, a grinding disc is rotatably arranged on the mounting plate, and a driving motor for driving the grinding disc to rotate is installed on the other side of the mounting plate, a rotating mechanism for driving the gear to rotate is provided on the workbench, a vertical plate is fixed to the workbench, and a square rod is slidably arranged on the vertical plate, a rack is fixed to one end of the square rod, and a spring is sleeved on the square rod, and the two ends of the spring are respectively against the rack and the vertical plate.
[0008] The rotating mechanism includes a portal frame fixed to the side end of the workbench, a sliding sleeve is slidably arranged on the portal frame, a vertical rod is fixed to the side end of the screw motor, a round rod is fixed to the vertical rod, a connecting rod is rotatably connected to the end of the round rod, the other end of the connecting rod is hinged to the side end of the sliding sleeve, a moving plate is fixed below the sliding sleeve, an inclined metal sheet is fixed on the moving plate, and a pulling component for pulling the rack is provided on the moving plate.
[0009] When the gear is moved to the middle position, the gear will be ground, and the sliding sleeve is at the position farthest from the gear motor. After grinding a tooth gap, the gear motor moves up or down, and the sliding sleeve will move in the direction close to the gear motor. At this time, the moving plate will drive the inclined metal sheet to move, and the moving plate will pull the rack outward through the pulling assembly, and the inclined metal sheet gear will rotate a tooth pitch, and then the rack will reset under the action of the spring and mesh with the gear again to fix the gear. When the gear motor moves from both ends to the middle, the sliding sleeve moves in the direction away from the gear motor. At this time, the rack will prevent the gear from rotating, and the inclined metal sheet will bend and deform when passing the gear and pass over the gear, and will not drive the gear to rotate. This can be repeated to drive the gear to rotate after grinding, and the next tooth gap can be ground, thereby realizing automatic grinding.
[0010] The movable plate is provided with a sliding hole, an adjusting rod is slidably arranged in the sliding hole, an inclined metal sheet is fixed to the end of the adjusting rod, a hand-tightening bolt is threadedly connected to the side end of the movable plate, and the end of the hand-tightening bolt abuts against the adjusting rod.
[0011] With the above structure, the operator can change the distance between the inclined metal sheet and the gear by adjusting the position of the rod and fix it by hand-tightening the bolt. Changing the distance between the inclined metal sheet and the gear can change the angle of rotation of the gear at a single time of the inclined metal sheet. After debugging, it can be ensured that the gear is only driven to rotate a distance of one tooth each time, thereby realizing the sequential grinding of the tooth gaps.
[0012] The pulling assembly includes a fixed rod fixed on the workbench, a pulling rod is rotatably arranged on the upper end of the fixed rod, a long slot is opened at one end of the pulling rod, a protrusion is fixed on the square rod, and the protrusion is slidably arranged inside the long slot, an iron block is fixed at the other end of the pulling rod, and a magnetic block is fixed at the side end of the movable plate.
[0013] With the above structure, when the movable plate moves toward the direction close to the screw motor, the magnetic block will absorb the iron block, so that the pulling rod will rotate along the fixed rod, and the square rod will be pulled by the protrusion to make the rack move away from the gear, thereby achieving the unlocking effect. After unlocking, the rack cannot move further after being pulled to a certain position. At this time, the magnetic block will separate from the iron block, and under the action of the spring, the rack will mesh with the gear again, thereby ensuring the stability of the gear during grinding.
[0014] A collection box is arranged below the through hole, a placement hanging plate is fixed below the workbench, and the collection box is placed on the placement hanging plate.
[0015] With the above structure, during grinding, the driving motor drives the grinding disc to grind the gear, and the powder and debris generated during grinding will fall into the collection box for subsequent processing.
[0016] Compared with the existing technology, this compact gear grinding machine with high stability has the following advantages:
[0017] 1. The gear can be ground through the screw motor, center column, grinding disc, rotating mechanism and rack, and the gear can be ground automatically one circle at a time. The structure is simple, the space occupied is small, the cost is low, and the gear is fixed by the rack during grinding, so the grinding stability is high.
[0018] 2. Through the rotating mechanism, the gear can be rotated in the gap of grinding, which can realize automatic production. There is no need for manual adjustment by the operator, which makes the production more efficient. In addition, the distance between the inclined metal sheet and the gear can be adjusted, which is convenient for the operator to debug the device.
[0019] 3. By pulling the machine assembly, the rack can clamp the gear again under the action of the spring after the gear rotates a certain angle, which can improve the stability during grinding, and the structure is simple and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

After grinding a tooth gap, the screw motor 5 moves upward or downward, and the sliding sleeve 902 moves toward the direction close to the screw motor 5. At this time, the moving plate 906 drives the inclined metal sheet 907 to move, and the moving plate 906 pulls the rack 12 outward through the pulling assembly. The inclined metal sheet 907 gear rotates a tooth pitch, and then the rack 12 is reset under the action of the spring 13 and meshes with the gear again to fix the gear. When the screw motor 5 moves from both ends to the middle, the sliding sleeve 902 moves away from the screw motor 5. At this time, the rack 12 prevents the gear from rotating.

Changing the distance between the inclined metal sheet 907 and the gear can change the angle of rotation of the inclined metal sheet 907 in a single shift of the gear. After debugging, it can be ensured that the gear is only driven to rotate a distance of one tooth each time, thereby realizing the sequential grinding of the tooth gap.
[0031] The pulling assembly includes a fixed rod 911 fixed on the workbench 1, and a pulling rod 912 is rotatably provided on the upper end of the fixed rod 911, and a long slot 913 is opened at one end of the pulling rod 912, a protrusion 914 is fixed on the square rod 11, and the protrusion 914 is slidably set inside the long slot 913, an iron block 915 is fixed to the other end of the pulling rod 912, and a magnetic block 916 is fixed to the side end of the movable plate 906; when the movable plate 906 moves in the direction close to the screw motor 5, the magnetic block 916 will absorb the iron block 915, so that the pulling rod 912 rotates along the fixed rod 911, and the square rod 11 is pulled by the protrusion 914, so that the rack 12 is away from the gear, thereby achieving an unlocking effect, and after unlocking, the rack 12 cannot continue to move after being pulled to a certain position, and at this time the magnetic block 916 will separate from the iron block 915, and under the action of the spring 13, the rack 12 will mesh with the gear again to ensure the stability of the gear during grinding.

[0033] In this embodiment, the above-mentioned fixing methods are the most commonly used fixing connection methods in this field, such as welding, bolt connection, etc.; the above-mentioned electrical components, such as the drive motor 8 and the screw motor 5, etc., are all existing technology products and can be directly purchased and used in the market, and the specific principles will not be repeated.
[0034] The working principle of this utility model:
[0035] When in use, the gear sleeve to be polished is set on the central column 2, and the polishing disc 7 is driven to rotate by the driving motor 8. During the up and down movement of the screw motor 5, the sliding sleeve 902 is driven to reciprocate along the upper end of the door frame 901 through the connecting rod 905. When the screw motor 5 moves to the middle position, the gear is ground, and at this time, the sliding sleeve 902 is located at the position farthest from the screw motor 5. After polishing a tooth gap, the screw motor 5 moves up or down, which will move the sliding sleeve 902 in the direction close to the screw motor 5. At this time, the moving plate 906 will drive the inclined metal sheet 907 to move, and the moving plate 906 pulls the rack 12 outward through the pulling rod 912. The inclined metal sheet 907 drives the gear to rotate a tooth pitch, and the rack 12 cannot move further after being pulled to a certain position. At this time, the magnetic block 916 will separate from the iron block 915, and the spring Under the action of 13, the rack 12 will mesh with the gear again to ensure the stability of the gear during grinding. When the screw motor 5 moves from both ends to the middle, the sliding sleeve 902 moves away from the screw motor 5. At this time, the rack 12 will prevent the gear from rotating. When the inclined metal sheet 907 passes through the gear, it will bend and deform and pass over the gear, and will not drive the gear to rotate. Repeating this process can drive the gear to rotate after grinding and grind the next tooth gap to achieve automatic grinding. In addition, the operator can change the distance between the inclined metal sheet 907 and the gear by adjusting the position of the rod 909 and fix it by hand-tightening the bolt 910. Changing the distance between the inclined metal sheet 907 and the gear can change the angle of rotation of the inclined metal sheet 907 at a single time. After debugging, it can be ensured that the gear is only driven to rotate a distance of one tooth each time, thereby ensuring the grinding accuracy.
[0036] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
