Description

Technical Field

[0001] This utility model relates to the field of cylindrical pin locking technology, specifically a locking device based on cylindrical pin machining. Background Technology

[0002] Cylindrical pins are a commonly used positioning element in mechanical design. They are characterized by simple structure, easy manufacturing, and reliable use. They can be used not only for overall positioning but also for separate positioning and positional positioning. There are various types of cylindrical pins, such as ordinary cylindrical pins, internal threaded cylindrical pins, and threaded cylindrical pins.

[0003] Chinese patent CN218476455U discloses a positioning device for machining cylindrical mechanical parts. It includes a mounting plate and a positioning block. The positioning block has a limiting cavity containing the part body. Several extrusion chambers are symmetrically arranged on the outer side of the limiting cavity. A T-shaped rod and an arc-shaped locking block are symmetrically slidably inserted around the center of the positioning block. A spring is fitted on the outer side of the horizontal part of the T-shaped rod, positioned between one side of the arc-shaped locking block and one side of the inner wall of the extrusion chamber. In this invention, an extrusion chamber is provided within the limiting cavity of the positioning block. An arc-shaped locking block is located within the extrusion chamber via the T-shaped rod. Under the spring's rebound, the arc-shaped locking block clamps and positions the outer side of the part body. Furthermore, a suction cup in the groove below the limiting cavity better adsorbs and limits the bottom surface of the part body, thus better adapting to cylindrical mechanical parts of different diameters and greatly improving work efficiency.

[0004] However, it still has the following drawbacks: the device uses the elastic force of a spring and the suction force of a suction cup to clamp and position the cylindrical rod, but during processing, because the workpiece is not locked, it may shake violently, affecting the final product quality. Therefore, we propose a locking device based on cylindrical pin machining to solve this problem. Summary of the Invention

[0005] The purpose of this invention is to provide a locking device based on the machining of cylindrical pins, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a locking device for machining cylindrical pins, comprising a mounting shell, wherein a locking device is provided on the inner side of the mounting shell, and the locking device includes a clamping part;

[0007] The clamping part includes a clamping block, a sliding rod, a screw, a motor, a gear, a gear ring, a bevel gear ring, and a sleeve. The outer surface of the clamping block is fixedly connected to the outer surface of the sliding rod, and the outer surface of the clamping block is fixedly connected to the outer surface of the screw. The outer surfaces of the sliding rod and the sleeve slide through the inner wall of the mounting housing and extend to the outer side of the mounting housing. The gear is fixedly sleeved on the outer surface of the motor output shaft, and the gear ring is fixedly sleeved on the outer surface of the bevel gear ring. The bevel gear ring is rotatably sleeved on the outer surface of the mounting housing through a bearing.

[0008] A feeding section is provided at the rear of the mounting shell;

[0009] The feeding section includes a housing, a hydraulic rod, and a push plate. The outer surface of the rear end of the hydraulic rod is fixedly inserted through the inner wall of the housing and extends to the rear of the mounting housing. The front of the hydraulic rod output rod is fixedly connected to the back of the push plate.

[0010] A further improvement is that the clamping part also includes a connecting plate, a bracket, a bevel gear, and a positioning ring. The outer surface of the screw penetrates the inside of the sleeve and extends to the outside of the mounting shell. The outer surface of the screw is threadedly connected to the inner wall of the sleeve. The outer surfaces of the slide rod and the screw are both fixedly connected to the outer surface of the connecting plate. By setting up the sleeve, screw, slide rod, connecting plate, and clamping block, the screw can be driven to move by rotating the sleeve, so that the clamping block clamps and positions the cylindrical pin.

[0011] A further improvement is that a limiting groove is formed on the inner wall of the mounting shell, the outer surface of the positioning ring is slidably connected to the inner wall of the limiting groove, and the inner wall of the positioning ring is fixedly connected to the outer surface of the sleeve. By setting the positioning ring, it is convenient to limit the movement of the sleeve.

[0012] A further improvement is that the bevel gear is fixedly sleeved on the outer surface of the sleeve, and the outer surface of the bevel gear meshes with the outer surface of the bevel gear ring. By setting the bevel gear and the bevel gear ring, rotating the bevel gear ring facilitates the simultaneous rotation of four bevel gears, so that the four clamping blocks clamp the cylindrical pins at the same time, reducing the positioning error of multiple cylindrical pins.

[0013] A further improvement is that the outer surface of the gear meshes with the outer surface of the gear ring, the bottom surface of the motor is fixedly connected to the top surface of the bracket, and the outer surface of the bracket is fixedly connected to the outer surface of the mounting shell. By setting up the bracket, motor, gear, and gear ring, the motor is started, and the gear and gear ring facilitate the rotation of the bevel gear ring.

[0014] A further improvement is that a through hole is provided on the back of the mounting shell, the front of the shell is fixedly connected to the back of the mounting shell, and the outer surface of the push plate is slidably connected to the inner wall of the shell. By setting up the shell, the hydraulic rod and the push plate, the extension of the hydraulic rod is controlled, which facilitates the push plate to push the cylindrical pin for feeding.

[0015] A further improvement is that the feeding part also includes a magnetic block, and the front of the push plate has a groove. The outer surface of the magnetic block is fixedly connected to the inner wall of the push plate. The magnetic block attracts the cylindrical pin, making it easy to adjust the position of the cylindrical pin back and forth.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This locking device for processing cylindrical pins, by setting up clamping blocks, sliding rods, screws, connecting plates, motors, brackets, gears, gear rings, bevel gear rings, bevel gears, sleeves, and positioning rings, drives the screw to move by rotating the sleeve, so that the clamping blocks clamp the cylindrical pins and position them. The motor is started, and the gears, gear rings, bevel gear rings, and bevel gears drive the four clamping blocks to clamp the cylindrical pins simultaneously, which greatly reduces the installation error of multiple cylindrical pins and facilitates operations such as chamfering and drilling of the cylindrical pins; by setting up a housing, hydraulic rods, and push plates, the cylindrical pins are placed inside the housing, and the extension of the hydraulic rods can be controlled to control the feeding of the cylindrical pins; by setting up magnetic blocks, the attraction force of the magnetic blocks on the cylindrical pins makes it easy to adjust the position of the cylindrical pins backward.
