Description

Technical Field

[0001] This utility model relates to the field of gear block pressing technology, and more specifically, to a push-type gear block pressing auxiliary device. Background Technology

[0002] The gear shift block is a component in a transmission used to switch between different gears. In a manual transmission, the gear shift block is usually connected to the gear shift lever. The driver operates it to change the gear meshing state within the transmission, thereby enabling functions such as vehicle acceleration, deceleration, and reversing. Gear shift block press-fitting refers to the process of mechanically engaging and fixing the gear shift block with the lever.

[0003] A search revealed that Chinese Patent CN210476814U discloses a gear shift block pressing tool. This utility model uses the gear shift block pressing tool to mechanically press the gear shift block. The only manual operations required are placing the handle and gear shift block into the corresponding fixture and turning on the switch. This eliminates the need for long-term and laborious operation by workers, thus greatly saving manpower and improving the pressing efficiency and stability of the gear shift block, while also increasing the yield rate of assembled parts.

[0004] When the above-mentioned press-fitting auxiliary tool is used, the function of the spring clamping mechanism is to fix the gear block when the swing arm rotates, so as to prevent the gear block from falling out of the gear block clamp. However, during long-term use, the spring will experience mechanical fatigue, which will affect the fixing effect of the gear block and result in poor performance. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a push-type gear block pressing auxiliary device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a push-type gear block pressing auxiliary device, including a mounting frame, a first connecting frame, and a second connecting frame. The first connecting frame is fixedly installed at the bottom of the mounting frame, and the second connecting frame is located at the top of the first connecting frame. Both the first and second connecting frames are provided with pressing components. Each pressing component includes a stepper motor, a forward and reverse lead screw, a limiting rod, and two pressing plates. The two stepper motors are respectively fixedly installed on one side of the first and second connecting frames, and the output shaft ends of the two stepper motors are respectively fixedly connected to the two forward and reverse lead screws. The other ends of the two forward and reverse lead screws are movably connected to the first and second connecting frames through bearings. The two limiting rods are respectively fixedly connected to the first and second connecting frames, and one end of each of the two forward and reverse lead screws and the two limiting rods passes through four pressing plates.

[0007] Furthermore, two gaskets are provided on the opposite side of the first connecting frame and the second connecting frame, and the four gaskets are respectively fixedly installed on the four extrusion plates.

[0008] It can be seen that the above technical solution aims to improve the stability between the extrusion plate and the stop block.

[0009] Furthermore, a hydraulic cylinder is fixedly connected to the top of the second connecting frame, and the top of the hydraulic cylinder is fixedly connected to the mounting bracket.

[0010] Furthermore, two side plates are fixedly connected to both sides of the second connecting frame, and two sliding rods are movably arranged on each of the two side plates, with all four sliding rods fixedly installed inside the mounting bracket.

[0011] As can be seen, in the above technical solution, the two side plates and four sliding rods work together to limit the deflection of the second connecting frame.

[0012] Furthermore, a lubrication assembly is provided on the second connecting frame. The lubrication assembly includes an oil reservoir, an oil pipe, a nozzle, a valve, and a piston. The oil reservoir is fixedly installed on the top of the second connecting frame.

[0013] Furthermore, the two ends of the oil pipe are fixedly connected to the oil storage tank and the nozzle, respectively, the valve is fixedly installed on the oil pipe, and the bottom end of the piston extends into the interior of the oil storage tank.

[0014] Furthermore, a sealing baffle is movably connected to the front side of the mounting bracket via a snap fastener.

[0015] As can be seen, in the above technical solution, the sealing baffle is opened and the residual lubricating oil in the mounting bracket is cleaned.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model uses a stepper motor to drive the forward and reverse lead screws to rotate. The forward and reverse lead screws can drive two extrusion plates and two washers to move in opposite directions. The two extrusion plates and two washers press and fix the gear block. Similarly, the handle is placed at the bottom of the second connecting frame, and another extrusion component fixes the handle to the second connecting frame. The telescopic rod on the hydraulic cylinder extends and drives the second connecting frame to move downward, thereby driving the handle to move downward, so that the handle and the gear block press against each other. The operation is simple, it is convenient to clamp the handle and the gear block, and the effect is good.

[0018] 2. This utility model allows lubricating oil in the oil tank to enter the nozzle through the oil pipe after the valve is opened. The nozzle sprays lubricating oil downwards, which lubricates the connection between the handle and the gear block, reducing direct friction between the parts and facilitating the pressing of the handle and the gear block together. The piston is rotated and moved away from the oil tank, and then new lubricating oil is added to the oil tank. The structure is simple and easy to use. Attached Figure Description
