Description

Technical Field

[0001] The utility model relates to the technical field of pinion gear assembly, in particular to a pinion gear assembly device. Background Art

[0002] Pinion is a common mechanical transmission component, usually used to transmit torque and rotational motion. It consists of a set of gear teeth that can mesh with other gears or shafts to achieve rotational transmission. It is usually used in various mechanical equipment, such as automobile gearboxes, industrial machinery, power tools, etc., to transmit power and adjust the speed. They can be used in conjunction with other transmission devices such as large gears, chains, belts, etc. to achieve different transmission requirements. Due to their smaller size compared to large gears, they are often used in mechanical devices with more stringent space requirements. And because pinions are often used for high-speed transmission, they usually need to be precision-machined to ensure the accuracy and balance of the gears.

[0003] At present, the assembly processing of pinion gears usually requires a special assembly fixture or assembly tool to assist in the assembly. If the pinion gear needs to be assembled in a centering manner with other components (such as shafts), it may be necessary to design a centering positioning device to ensure that the axes of the pinion gear and other components are aligned. However, since most of the existing assembly equipment is fixed, it can only be applied to pinions of a specific type or size, and may not be able to adapt to pinions of different specifications, resulting in a high manufacturing cost of the device, which is not suitable for small-batch production.

A limiting component is provided on the upper surface of the workbench 1, and a centering component is slidably connected to the middle of the workbench 1, and a clamping component is provided on the outer wall of the centering component.

[0023] Reference Figure 1The centering assembly includes a U-shaped frame 8, the outer wall of the U-shaped frame 8 is slidably connected to the middle of the workbench 1, so that after applying a downward pressure force to the U-shaped frame 8, the U-shaped frame 8 will move down in the middle of the workbench 1, one end of the U-shaped frame 8 is fixedly connected to a mounting plate 9, the outer wall of the mounting plate 9 is fixedly connected to a spring 2 10, and the other end of the spring 2 10 is fixedly connected to the lower surface of the workbench 1. When the U-shaped frame 8 moves down, the mounting plate 9 will drive the spring 2 10 to stretch, and then the spring 2 10 will generate a rebound reaction force, thereby facilitating the subsequent resetting of the U-shaped frame 8, and the middle of the workbench 1 A centering groove 13 is provided to ensure that the U-shaped frame 8 is in a centered position when it moves downward, so as to ensure the accuracy of the pinion assembly. A moving cylinder 11 is slidably connected to the lower surface of the workbench 1, and a spring three 12 is fixedly connected to the inner wall of the moving cylinder 11. The other side of the spring three 12 is fixedly connected to the lower surface of the workbench 1. When pushed by the U-shaped frame 8, the moving cylinder 11 will drive the spring three 12 to stretch, so that the spring three 12 also generates a rebound reaction force, which is convenient for coordinating with the spring two 10 to help the U-shaped frame 8 to automatically reset after the downward pressure applied to the frame disappears.

[0024] The outer wall of the U-shaped frame 8 and the interior of the centering groove 13 are on the same horizontal line.

[0025] Reference Figure 3 The clamping assembly includes a bidirectional screw rod 15, the middle part of which is rotatably connected to the upper part of the U-shaped frame 8, and the left and right sides of the bidirectional screw rod 15 are threadedly connected with moving rods 17. The outer wall of the U-shaped frame 8 is provided with a limiting groove 19, and the outer walls of the two moving rods 17 are slidably connected to the inner wall of the limiting groove 19. The bottoms of the two moving rods 17 are fixedly connected with an arc plate 18. After the bidirectional screw rod 15 is rotated, the moving rods 17 on both sides can be controlled to move relative to or oppositely, so as to be flexibly adjusted according to the size of the parts to be assembled, and the limiting groove 19 can limit the moving direction of the moving rod 17 to keep it moving in a straight line, thereby ensuring that the parts to be assembled are aligned with the center of the pinion, thereby achieving precise alignment of the assembly components, thereby ensuring the accuracy of the equipment, and thus improving the assembly quality and performance of the pinion.

[0026] A handle 16 is fixedly connected to the outer wall of the bidirectional screw rod 15 , and the handle 16 is convenient for controlling the rotation of the bidirectional screw rod 15 .

The outer wall of the arc-shaped limiting rod 7 is slidably connected to the inner wall of the limiting groove 14. After the arc-shaped limiting rod 7 is rotated, the arc-shaped limiting rod 7 can be moved in and out of the inner wall of the limiting groove 14, so that the U-shaped rod will not move at will when installing the components to be assembled.

[0028] Reference Figure 2 A cavity 20 is formed on the upper surface of the workbench 1 .

[0029] Working principle: when assembling the pinion gears, first place the pinion gears to be assembled on opposite sides of the multiple contact plates 6, and then, driven by the diameter size of the pinion gears, the distance between the multiple contact plates 6 is expanded, and then the moving frame 5 is driven to move inside the mounting groove 2, and the movable plate 4 squeezes the spring 1 3, and then the spring 1 3 is compressed to generate a rebound reaction force, which is applied to the multiple contact plates 6, and then the multiple contact plates 6 are controlled to squeeze the pinion gears, so that the pinion gears are fixed on the top of the workbench 1, and then the parts to be assembled are placed on opposite sides of the two arc plates 18, and then the bidirectional screw rod 15 is rotated by controlling the handle 16, and driven by the rotation of the bidirectional screw rod 15, the moving rods 17 on both sides move relative to or oppositely along the inside of the limit groove 2 19, and at this time, with the movement of the moving rods 17 on both sides, the arc plates 18 on both sides clamp and fix the pinion gears, and then By rotating the arc limit rod 7, the arc limit rod 7 is moved out from the inside of the limit groove 14, and the fixation of the U-shaped frame 8 is released. Subsequently, the U-shaped frame 8 is pressed downward, so that the U-shaped frame 8 drives the components to be assembled to move downward and contact the gear, and the U-shaped frame 8 drives the mounting plate 9 to move downward, thereby stretching the spring 2 10, so that the spring 2 10 produces a rebound reaction force, and the U-shaped frame 8 enters the inside of the centering groove 13, thereby applying downward pressure to the moving cylinder 11, and then the moving cylinder 11 drives the spring 3 12 to stretch, so that the spring 3 12 produces a rebound reaction force. At this time, after the driven components and the pinion are assembled, the downward pressure applied to the U-shaped frame 8 is cancelled, so that under the rebound reaction force of the spring 2 10 and the spring 3 12, the U-shaped frame 8 is driven to reset, and then the arc limit rod 7 can be rotated to make the arc limit rod 7 enter the inside of the limit groove 14, and the height of the U-shaped frame 8 is fixed again, so as to continue to assemble the next component.
