Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing, and in particular to tooling fixtures for sheet metal processing. Background Technology

[0002] Sheet metal work is a comprehensive cold-working process for thin metal sheets, including shearing, punching / cutting / combined cutting, bending, welding, riveting, splicing, and forming (such as car bodies). Its most significant characteristic is that the thickness of the same part is consistent. Products processed through sheet metal work are called sheet metal parts. The term "sheet metal part" generally varies across different industries and is often used in assembly contexts.

[0003] When processing sheet metal parts, since the shape of the sheet metal parts is not fixed, the common method of fixing them is to use tooling fixtures for limiting their position. Generally, tooling blocks are installed on a horizontal plate, and the tooling blocks are arranged in a certain shape to limit the sheet metal parts. The processing equipment processes the sheet metal parts from above. Although this edge-fixing method can limit the sheet metal parts to a certain extent, in actual operation, although the sheet metal parts can be fixed in the horizontal direction, when the processing equipment moves the sheet metal parts, such as when pressing rivets, drilling, or punching, the sheet metal parts tend to move upwards with the processing equipment, which can easily cause shaking and displacement, affecting the processing quality of sheet metal. Therefore, a tooling fixture for sheet metal parts processing is proposed to address the above problems. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a tooling fixture for sheet metal processing. By activating the fixing mechanism, the first suction cup and the second suction cup are installed inside the second fixing clamp and close to the sheet metal part. At this time, the first suction cup and the second suction cup can adsorb the sheet metal part, so that the sheet metal part is kept fixed and will not shake or shift.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a tooling fixture for sheet metal processing, including a base plate; The upper surface of the base plate is equipped with a first fixing clamp, a pad, and a second fixing clamp; Sheet metal parts can be placed on top of the pad; The second fixing plate has a fixing mechanism installed inside; The fixing mechanism includes a mounting frame, inside which a supply solenoid valve is installed. One end of the supply solenoid valve is connected to a positive pressure air pipe, and the other end of the positive pressure air pipe is connected to an external air pump device. The outside of the supply solenoid valve is connected to a first negative pressure air pipe, and the other end of the first negative pressure air pipe is connected to a first suction cup, which is installed inside the second fixed clamping plate. A vacuum generator is installed on the outside of the first negative pressure air pipe; The outer side of the first negative pressure air pipe is fixedly connected to the mounting frame.

[0006] Furthermore, a second negative pressure air pipe is connected to the outside of the first negative pressure air pipe, and a second suction cup is connected to the other end of the second negative pressure air pipe. The second suction cup is installed inside the second fixed clamp.

[0007] Furthermore, the air intake ends of both the first and second suction cups face the sheet metal part.

[0008] When processing sheet metal parts, since the shape of sheet metal parts is not fixed, the common method of fixing them is to use tooling fixtures for limiting. Generally, tooling blocks are installed on a horizontal plate, and the tooling blocks are arranged in a certain shape to limit the sheet metal parts. The processing equipment processes the sheet metal parts from above. Although this edge-fixing method can limit the sheet metal parts to a certain extent, in actual operation, the sheet metal parts can be fixed in the horizontal direction, but when the processing equipment moves the sheet metal parts, the sheet metal parts may move upward with the processing equipment. Vertically, they are prone to shaking, which affects the processing of sheet metal parts. When using the technical solution of this application, the operator places the sheet metal part inside the first fixed clamping plate and the second fixed clamping plate. By activating the fixing mechanism, the first suction cup and the second suction cup are installed inside the second fixed clamping plate and close to the sheet metal part. At this time, the first suction cup and the second suction cup can adsorb the sheet metal part. When the processing equipment moves up and removes the sheet metal part, it will not cause the sheet metal part to separate from the first fixed clamping plate and the second fixed clamping plate, thereby achieving vertical fixation of the sheet metal part. This effectively fixes the sheet metal part and ensures that there will be no shaking during the processing of the sheet metal part.

[0009] Furthermore, there are multiple first and second fixing plates, both of which are vertically arranged, and both the first and second fixing plates are fixed to the top of the base plate by screws.

[0010] Furthermore, both the first and second fixing plates are curved on the side of the sheet metal part facing upwards.

[0011] The first and second fixing plates have curved surfaces facing the sheet metal parts, which facilitates the smooth placement of the sheet metal parts inside the first and second fixing plates and serves as a guide.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When the sheet metal part is placed inside the first fixed clamping plate and the second fixed clamping plate, the first suction cup and the second suction cup are installed inside the second fixed clamping plate and close to the sheet metal part by activating the fixing mechanism. At this time, the first suction cup and the second suction cup can adsorb the sheet metal part. When the processing equipment moves up and removes the sheet metal part, it will not cause the sheet metal part to separate from the first fixed clamping plate and the second fixed clamping plate, thereby locking the vertical direction of the sheet metal part and preventing the sheet metal part from shaking or shifting, thus effectively ensuring the processing quality of the sheet metal part. 2. An arc surface is provided on the surface of the first fixed clamping plate and the second fixed clamping plate facing the sheet metal part. This facilitates the smooth placement of the sheet metal part inside the first fixed clamping plate and the second fixed clamping plate, and serves as a guide. Attached Figure Description

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

A supply solenoid valve 602 is installed inside the mounting frame 601. One end of the supply solenoid valve 602 is connected to a positive pressure air pipe 603, and the other end of the positive pressure air pipe 603 is connected to an air pump device. The outside of the supply solenoid valve 602 is connected to a first negative pressure air pipe 604, and the other end of the first negative pressure air pipe 604 is connected to a first suction cup 606. The first suction cup 606 is installed inside the second fixed clamping plate 5. A vacuum generator 605 is installed on the outside of the first negative pressure air pipe 604; The outer side of the first negative pressure air pipe 604 is fixedly connected to the mounting frame 601.

[0017] The outer side of the first negative pressure air pipe 604 is connected to the second negative pressure air pipe 607, and the other end of the second negative pressure air pipe 607 is connected to the second suction cup 608, which is installed inside the second fixed clamping plate 5.

[0018] The air intake ends of the first suction cup 606 and the second suction cup 608 both face the sheet metal part 3.

[0019] When processing sheet metal parts, since the shape of sheet metal parts is not fixed, the common method of fixing them is to use tooling fixtures for limiting. Generally, tooling blocks are installed on a horizontal plate, and the tooling blocks are arranged in a certain shape to limit the sheet metal parts. The processing equipment processes the sheet metal parts from above. Although this edge-limiting fixing method can limit the sheet metal parts to a certain extent, in actual operation, the sheet metal parts can be fixed in the horizontal direction, but when the processing equipment moves the sheet metal parts, the sheet metal parts may move upward with the processing equipment. In the vertical direction, they are prone to shaking and displacement, which will affect the processing quality of the sheet metal parts. When using the technical solution of this application, the operator places the sheet metal part 3 inside the first fixed clamping plate 2 and the second fixed clamping plate 5. By activating the fixing mechanism 6, the first suction cup 606 and the second suction cup 608 are installed inside the second fixed clamping plate 5 and close to the sheet metal part 3. The air pump device (not shown in the figure) is activated. When the airflow passes through the vacuum generator 605, the first suction cup 606 and the second suction cup 608 can adsorb the sheet metal part 3. When the processing equipment moves up and removes the sheet metal part 3, it will not cause the sheet metal part 3 to separate from the first fixed clamping plate 2 and the second fixed clamping plate 5, thereby achieving vertical fixation of the sheet metal part 3 and effectively ensuring the processing quality of the sheet metal part 3. The supply solenoid valve 602 is controlled by an external controller. The vacuum generator 605 and the air pump are both existing products in this field. Their internal principles and connection circuits are also existing technologies, so they will not be described in detail here. After the sheet metal part 3 is processed, the supply solenoid valve 602 is closed, which ensures that the sheet metal part 3 can be removed smoothly.

[0020] Multiple first fixing plates 2 and two fixing plates 5 are arranged vertically, and both the first fixing plates 2 and the second fixing plates 5 are fixed to the top of the base plate 1 by screws.

[0021] Both the first fixing plate 2 and the second fixing plate 5 are curved on the side facing the sheet metal part 3.

[0022] An arc surface is provided on the surface of the first fixed clamping plate 2 and the second fixed clamping plate 5 facing the sheet metal part 3, which facilitates the smooth placement of the sheet metal part 3 inside the first fixed clamping plate 2 and the second fixed clamping plate 5, and serves as a guide. Both the first fixing plate 2 and the second fixing plate 5 can be installed according to the actual shape of the sheet metal part 3, thus expanding the scope of application.

[0023] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
