A machining fixture for cutting the shape of a diaphragm

Abstract

This utility model discloses a processing fixture for cutting the shape of a diaphragm, including a plate and a worktable. The plate is located above the worktable, and the surface of the plate is provided with multiple cutting positions. A support is provided on one side of the worktable, and limiting grooves are provided at both ends of the worktable. A first pressure roller and a second pressure roller are provided above the worktable, and a first conveying roller and a second conveying roller are respectively provided below the first pressure roller and the second pressure roller. This utility model restricts the position of the plate by pressing it with the pressure roller and the conveying roller. Then, the two pressure rollers and the two limiting plates form a processing space, and the plate is laser-cut inside the processing space. This allows the laser emitter to move only inside the processing space, reducing the movement distance required for the laser emitter to reset after completing the cutting of the entire plate, reducing the preparation time required before laser cutting, and improving the efficiency of diaphragm processing.

Description

Technical Field

[0001] This utility model relates to the field of diaphragm cutting, and in particular to a processing tool for cutting the shape of a diaphragm. Background Technology

[0002] The core component of a high-power wind turbine coupling is a specially treated diaphragm assembly. These diaphragms alternately connect the bushing and the intermediate tube and are fixed with high-strength bolts, thereby ensuring strong correction capability and high power density.

[0003] The diaphragm processing procedure involves first laser cutting the sheet material, then heat treatment to eliminate overall stress, and finally shot blasting to remove burrs. Existing laser cutting methods involve fixing the sheet material on a worktable and then using a drive system to move the laser emitter along the X, Y, and Z axes for cutting. However, the sheet material is relatively long along the Y axis. After cutting the entire sheet, the laser emitter is located at the tail end of the sheet and needs to be reset before cutting again. This results in the laser emitter wasting a significant amount of time moving, leading to low efficiency in laser cutting diaphragm shapes. Therefore, a new machining fixture for diaphragm shape cutting is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a processing fixture for cutting the shape of a diaphragm, so as to solve the problem of low efficiency when laser cutting the shape of a diaphragm as mentioned in the background art. The technical solution of this utility model provides a solution that is significantly different from the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A processing fixture for cutting the shape of a diaphragm includes a plate and a worktable. The plate is located above the worktable, and its surface has multiple cutting positions. A support is provided on one side of the worktable, and multiple rotatable rollers are arranged inside the support. Limiting grooves are provided at both ends of the worktable. A first pressure roller and a second pressure roller are arranged above the worktable. A first conveying roller and a second conveying roller are respectively arranged below the first pressure roller and the second pressure roller. Positioning seats are provided at both ends of the first pressure roller and the second pressure roller. An adjustable limiting mechanism for limiting the position of the plate is provided inside the limiting groove. A first driving mechanism for driving the first pressure roller and the second pressure roller to move is provided above the positioning seat. A second driving mechanism for driving the first conveying roller and the second conveying roller to rotate simultaneously is provided on one side of the worktable.

[0007] Preferably, the adjustable limiting mechanism includes a limiting plate and a pad, and a threaded post passing through the limiting plate and the pad is provided inside the limiting groove. The limiting plate has an L-shaped structure, and the limiting plate and the pad are fixed to the threaded post by a nut.

[0008] Preferably, the first driving mechanism is an electric telescopic rod, which is mounted on the positioning seat. Both ends of the first and second pressure rollers are provided with sliders, which slide inside the positioning seat. The piston rod inside the electric telescopic rod is connected to the sliders.

[0009] Preferably, the second drive mechanism is a motor, and one end of the first conveyor roller and the second conveyor roller are respectively provided with a drive wheel and a driven wheel. The drive wheel is connected to the motor shaft, and the drive wheel and the driven wheel are connected by a belt.

[0010] Preferably, there are several partitions between the first and second conveyor rollers, with protrusions at the upper end of the partitions. The partitions are connected to the worktable via fixed plates, and a conveyor belt is provided below the partitions. After the sheet is cut, the film passes through the space between the two partitions and falls onto the conveyor belt.

[0011] Preferably, the surfaces of the first pressure roller, the second pressure roller, the first conveying roller, and the second conveying roller are all provided with anti-slip rubber. The first pressure roller and the second pressure roller are in contact with the upper surface of the plate, and the first conveying roller and the second conveying roller are in contact with the lower surface of the plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses an electric telescopic rod to lower the first and second pressure rollers, causing the first pressure roller, the first conveyor roller, the second pressure roller, and the second conveyor roller to clamp the sheet metal. At this time, the first pressure roller, the second pressure roller, and the two limiting plates form a processing space, which can be used to laser cut the sheet metal inside the processing space. Afterward, the first and second conveyor rollers rotate to transport the unprocessed part of the sheet metal into the processing space for laser cutting. This allows the laser emitter to move only inside the processing space, reducing the distance the laser emitter needs to move to reset after completing the entire sheet metal cutting, reducing the preparation time required before laser cutting, and improving the efficiency of film processing.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4In this utility model, a processing fixture for cutting the shape of a diaphragm includes a plate 1 and a worktable 2. The plate 1 is located above the worktable 2. The surface of the plate 1 is provided with multiple cutting positions 101. A support 202 is provided on one side of the worktable 2. Multiple rotatable rollers 2021 are provided inside the support 202. Limiting grooves 204 are provided at both ends of the worktable 2. A first pressure roller 5 and a second pressure roller 501 are provided above the worktable 2. A first conveying roller 6 and a second conveying roller 602 are respectively provided below the first pressure roller 5 and the second pressure roller 501. Positioning seats 201 are provided at both ends of the first pressure roller 5 and the second pressure roller 501. A limiting plate 4 and a pad 401 are provided inside the limiting groove 204. An electric telescopic rod 203 is provided on the top of the positioning seat 201. A motor 3 is provided on one side of the worktable 2.

[0023] Example 1: Please refer to Figure 1-4 In this embodiment of the present invention, a processing fixture for cutting the shape of a diaphragm is provided. A limiting plate 4 and a pad 401 pass sequentially through a threaded post 2041. The limiting plate 4 has an L-shaped structure. The limiting plate 4 and the pad 401 are fixed to the threaded post 2041 by a nut. The nut restricts the limiting plate 4 from moving...

[0024] The position of the threaded post 2041 allows the sides of the two limiting plates 4 to fit against the two ends of the plate 1, thereby limiting the position of the plate 1. By changing the position of the limiting plates 4 on the threaded post 2041 with nuts, the distance between the two limiting plates 4 can be adjusted to accommodate plates of different widths.

[0025] The electric telescopic rod 203 is mounted on the positioning seat 201. Both ends of the first pressure roller 5 and the second pressure roller 501 are provided with sliders. The sliders slide inside the positioning seat 201. The piston rod inside the electric telescopic rod 203 is connected to the sliders. One end of the first conveyor roller 6 and the second conveyor roller 602 is respectively provided with a driving wheel 601 and a driven wheel 603. The driving wheel 601 is connected to the shaft of the motor 3. The driving wheel 601 and the driven wheel 603 are connected by a belt.

[0026] The surfaces of the first pressure roller 5, the second pressure roller 501, the first conveyor roller 6, and the second conveyor roller 602 are all provided with anti-slip rubber. The first conveyor roller 6 and the second conveyor roller 602 are in contact with the bottom of the plate 1. When the four electric telescopic rods 203 drive the first pressure roller 5 and the second pressure roller 501 to move downward, so that the first pressure roller 5, the first conveyor roller 6, the second pressure roller 501, and the second conveyor roller 602 clamp the plate 1, the first pressure roller 5, the second pressure roller 501, and the two limiting plates 4 form a processing space. The laser emitter processes the cut position 101 of the plate 1 inside the processing space. Then, the motor 3 drives the first conveyor roller 6 and the second conveyor roller 602 to rotate, and transports the unprocessed part of the plate 1 into the processing space for laser cutting. This allows the laser emitter to move only inside the processing space, reducing the moving distance required for the laser emitter to reset after completing the cutting of the entire plate 1, reducing the preparation time required before laser cutting, and improving the efficiency of film processing.

[0027] Several partitions 7 are located between the first conveyor roller 6 and the second conveyor roller 602. The upper end of the partition 7 is provided with a protrusion 701. The partition 7 is connected to the worktable 2 through a fixing plate 702. A conveyor belt is provided below the partition 7. When the cutting position 101 on the plate 1 is cut, the processed film falls through the space between the two partitions 7 onto the conveyor belt.

[0028] The working principle of this utility model is as follows: the plate 1 is clamped by the first pressure roller 5, the first conveying roller 6, the second pressure roller 501, and the second conveying roller 602, which restricts the position of the plate 1 in the front-back direction. The position of the plate 1 in the left-right direction is restricted by the two limiting plates 4. The first pressure roller 5, the second pressure roller 501, and the two limiting plates 4 form a processing space. The laser emitter processes the cutting position 101 of the plate 1 inside the processing space. Then, the motor 3 transports the unprocessed part of the plate 1 into the processing space for laser cutting. This allows the laser emitter to move only inside the processing space, reducing the distance the laser emitter needs to move to reset after completing the cutting of the entire plate 1, reducing the preparation time required before laser cutting, and improving the efficiency of film processing.
