Description

Technical Field

[0001] The utility model relates to the technical field of gear processing positioning, in particular to a gear processing positioning device. Background Technique

[0002] A gear refers to a mechanical element with teeth on the rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. Existing gear processing devices cannot adjust and position and fix the gear blank in a timely manner according to its size, and can only fix it through washers, bolts, etc. The disassembly is cumbersome, consuming a large amount of processing time and having the disadvantage of low processing efficiency. For example, the gear processing positioning device described in the utility model with the publication number CN214392670U includes a hollow structure placement table. A snap base is fixedly installed on the outer wall of one side of the placement table. A first rotating shaft is rotatably installed at the upper end of the snap base, and a first snap is rotatably connected to the first rotating shaft. This utility model can adjust and position and fix the gear blank in a timely manner according to its size, and the disassembly of the workpiece is simple and convenient. However, when working with a manual transmission rod, it slides and horizontally moves on the first support column, causing the first pressing column to move to fix the gear. Since the second pressing column is fixed, after fixing different gears, the center of the gear is not concentric with the processing shaft. Subsequently, a new reference needs to be set through calibration, so that calibration is required every time after clamping before processing, affecting the processing efficiency. Therefore, it is necessary to develop a gear processing positioning device for the above-mentioned defects. Content of the Utility Model

[0003] The purpose of the utility model is to provide a gear processing positioning device, which controls the chucks to move relatively or towards each other simultaneously through a sliding component, so that the center of the clamped gear is consistent with the center of the processing shaft, reducing the gear calibration time, optimizing the processing process, and improving the production efficiency.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A gear processing positioning device of the utility model includes a placement table. Four sliding grooves are evenly arranged on the placement table. Two of the sliding grooves are in the horizontal direction and two are in the vertical direction. A chuck is slidably installed in each sliding groove. A sliding component is arranged at the lower end of each chuck, and a driving component is installed at the lower end of the sliding component. The driving component controls the movement of the four chucks at the upper end to position the inner hole of the gear. Pressing components are installed at the upper ends of the two chucks in the horizontal direction. The pressing components press on the upper end surface of the gear body, so that the gear body is pressed against the placement table.

[0006] Preferably, the sliding assembly includes a rotating disk, a connecting rod, a slider, and a rotating shaft. The rotating shaft is fixedly installed at the center of the placement table. The rotating disk is rotatably connected to the rotating shaft. The rotating disk has a square structure. The four corners of the rotating disk are rotatably connected to the connecting rod through a pin shaft. The end of the connecting rod away from the rotating disk is hinged to the lower end surface of the slider. The slider is guidingly installed at the lower end of the sliding groove. The chuck is fixedly installed on the upper end surface of the slider. The upper end surface of the slider is flush with the lower end surface of the placement table.

[0007] Preferably, the driving assembly includes an electric telescopic rod. The electric telescopic rod is installed at the lower end of the chuck in the horizontal direction. The lower end of the slider at the fixed end of the electric telescopic rod is fixedly connected to a bracket. A through hole is provided at the bottom end of the bracket. A connecting rod passes through the through hole. The two ends of the connecting rod are fixedly connected to the front end of the output end of the electric telescopic rod. The electric telescopic rod is fixedly installed at the lower end of the placement table through a support block.

[0008] Preferably, the pressing assembly includes a first cylinder, a fixed seat, a second cylinder, and a pressing head. The first cylinder is fixedly installed on the upper end surface of the chuck. The upper end surface of the first cylinder is fixedly connected to the fixed seat. The first cylinder drives the fixed seat to rotate 180°. The end of the fixed seat protruding from the first cylinder is fixedly connected to the second cylinder. The extending end of the second cylinder is fixedly connected to the pressing head. The second cylinder drives the pressing head to move up and down.

[0021] In a specific embodiment, as Figures 1 to 4As shown in the figure, a gear processing positioning device includes a placement table 1, and four feet are provided on the lower end surface of the placement table 1 for support. Two horizontal chutes 101 are provided on the placement table 1 in the horizontal direction, and two vertical chutes 101 are provided in the vertical direction. The horizontal chutes 101 and the vertical chutes 101 are not connected in the middle, and the two side chutes 101 are symmetrically arranged at the center of the placement table 1, which is convenient for the lower end rotating shaft 304 to be fixed at the center position of the placement table 1. A chuck 2 is provided in each chute 101, and the chuck 2 slides in the chute 101.

[0022] In a specific embodiment, as Figures 1 to 4 shown, a sliding assembly 3 is provided at the lower end of each chuck 2. The sliding assembly 3 includes a rotating disk 301, a connecting rod 302, a slider 303 and a rotating shaft 304. The rotating disk 301 is installed at the center position of the placement table 1 through the rotating shaft 304. The rotating disk 301 and the rotating shaft 304 are rotatably connected. The rotating shaft 304 is fixedly installed on the placement table 1. The rotating disk 301 is of a square structure. Four corners of the rotating disk 301 are respectively rotatably connected with connecting rods 302 through pins. The other ends of the connecting rods 302 are respectively hinged on the lower end surface of the slider 303. Driven by the connecting rod 302, the slider 303 moves linearly along the chute 101. The chuck 2 passes through the chute 101 and is fixedly installed on the upper end surface of the slider 303, so that the chuck 2 moves linearly in the chute 101 along with the slider 303.

[0023] In a specific embodiment, as Figures 1 to 4 shown, the sliding assembly 3 controls the movement of the four upper chucks 2 to position the inner hole of the gear through the driving assembly 4. The driving assembly 4 includes an electric telescopic rod 402. The electric telescopic rod 402 is installed at the lower end of the chuck 2 in the horizontal direction. A bracket 401 is fixedly connected to the lower end of the slider 303 at the fixed end of the electric telescopic rod. A through hole is provided at the bottom end of the bracket 401, and a connecting rod 403 passes through the through hole. There are two electric telescopic rods 402. The front ends of the output ends of the electric telescopic rods 402 are respectively installed at both ends of the connecting rod 403. The rear ends of the electric telescopic rods 402 are fixedly installed at the lower end of the placement table 1 through a support block 404.

[0024] In a specific embodiment, as Figures 1 to 4As shown in the figure, a pressing assembly 5 is installed at the upper ends of two chucks 2 in the horizontal direction, and the pressing assembly 5 presses the inner hole of the gear against the placing table 1. The pressing assembly 5 includes a first air cylinder 501, a fixed seat 502, a second air cylinder 503 and a pressing head 504. The first air cylinder 501 is fixedly installed on the upper end surface of the chuck 2, and the upper end surface of the first air cylinder 501 is fixedly connected with the fixed seat 502. The first air cylinder 501 drives the fixed seat 502 to rotate 180°. The first air cylinder 501 is a rotary air cylinder, which uses compressed air to drive the output shaft to make a reciprocating rotary motion within a certain angle range, and adjusts the swing angle through an adjusting bolt to achieve the required rotation angle. One end of the fixed seat 502 protruding from the first air cylinder 501 is fixedly connected with the second air cylinder 503, and the extending end of the second air cylinder 503 is fixedly connected with the pressing head 504. The second air cylinder 503 drives the pressing head 504 to move up and down.

[0025] The operation process of the gear processing positioning device of the present utility model: When installing the gear body, start the rotation of the first air cylinder 501, which will drive the fixed seat 502 to rotate, rotate the fixed seat 502 by 180°, so that the pressing head 504 turns to the inner side, avoiding interference with the pressing head 504 when installing the inner hole of the gear body on the chuck 2. Start the electric telescopic rod 402, and the output end of the electric telescopic rod 402 retracts, so that the rotating disc 301 drives the connecting rod 302 to rotate inwards, and the four chucks 2 retract to the minimum. After the gear body is placed on the placing table 1, start the electric telescopic rod 402, and the output end of the electric telescopic rod 402 extends, so that the rotating disc 301 drives the connecting rod 302 to rotate outwards, and the four chucks 2 move outwards along the sliding groove 101. Until the outer side surface of the chuck 2 fits against the inner wall of the inner hole of the gear body, the electric telescopic rod 402 stops working. Start the first air cylinder 501, and the first air cylinder 501 drives the fixed seat 502 to rotate 180°, so that the pressing head 504 installed at the front end of the fixed seat 502 faces the outside. Start the second air cylinder 503, and the second air cylinder 503 drives the pressing head 504 to move downwards, so that the pressing head 504 tightly presses the upper end surface of the gear body to prevent the gear body from rotating. When the electric telescopic rod 402 controls the movement of the chuck 2, while magnifying or reducing, the space formed by the four chucks 2 remains concentric with a processing shaft. During processing, only calibration according to the outer diameter size is required, and then processing can be carried out, which is convenient to operate.
