Description

Technical Field

[0001] The utility model relates to the technical field of fixture positioning, in particular to a pneumatic punch fixture for processing vacuum parts. Background Art

[0002] Vacuum components refer to various mechanical, electronic, optical, and thermal components used in a vacuum environment. Vacuum technology is widely used in scientific research, semiconductor manufacturing, vacuum packaging, optical coatings, and other fields. The manufacture and use of vacuum components require strict technical requirements and quality control.

[0003] However, in the prior art, when punching vacuum parts, in order to ensure the accuracy of the processing position, it is necessary to use a clamp to position the vacuum parts during processing. When clamping vacuum parts with uneven outer surfaces, the contact area between the clamp and the vacuum parts is small, which not only leads to unstable clamping effect, but also causes uneven force on the surface of the clamped vacuum parts, which can easily cause the surface of the vacuum parts to deform and affect the normal use of the vacuum parts. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that when a vacuum part is punched, in order to ensure the accuracy of the processing position, it is necessary to use a clamp to position the vacuum part during processing. When clamping a vacuum part with an uneven outer surface, the contact area between the clamp and the vacuum part is small, which not only leads to unstable clamping effect, but also causes uneven force on the surface of the clamped vacuum part, easily causing the surface of the vacuum part to deform, affecting the normal use of the vacuum part. A pneumatic punch clamp for vacuum part processing is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a pneumatic punching machine fixture for vacuum parts processing, comprising a lifting seat and a base, the inner side wall of the base is slidably connected to two fixture seats, the adjacent side walls of the two fixture seats are fixedly connected with elastic pads, and the vacuum part is placed between the two fixture seats for positioning processing, a processing punching groove is opened at the center position of the top surface of the lifting seat, and the punching machine processes the vacuum part through the processing punching groove, the bottom end of the lifting seat is fixedly connected to a triangular block, and the top surface of the fixture seat is opened with a triangular groove adapted to the shape of the triangular block.

[0006] Preferably, a slot is provided on the inner bottom wall of the lifting seat.

[0007] Preferably, the bottom end of the clamp seat is fixedly connected to a rail, and the rail is slidably connected to the elastic pad.

[0008] Preferably, a sealing plate is provided above the top end of the elastic pad, and the sealing plate is connected to the clamp seat by screws.

[0009] Preferably, the four corner positions of the lifting seat are all slidably connected to limiting columns, and the limiting columns are fixedly connected to the base.

[0010] Preferably, the outer side wall of the clamp seat is fixedly connected with a positioning shaft, and the positioning shaft is slidably connected to the outer side wall of the base.

[0011] Preferably, a spring is provided on the outer side wall of the positioning shaft, one end of the positioning shaft is fixedly connected to a baffle, one end of the spring is fixedly connected to the baffle, and the other end of the spring is fixedly connected to the outer side wall of the base.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] 1. In the utility model, two relatively movable clamp seats are arranged under the head of the pneumatic punch press, and elastic pads with a certain toughness and deformation ability are installed on the facing surfaces of the clamp seats. The vacuum part is placed between the two clamp seats. Pneumatic punch processing requires clamping and positioning of the vacuum part. The two clamp seats that squeeze each other are used to clamp and position the vacuum part in the middle. The elastic pad fits perfectly on the outer surface of the vacuum part, increasing the contact area with the vacuum part, avoiding the high-pressure deformation problem caused by single-point extrusion, and improving the clamping stability by increasing the clamping area, thereby meeting the high-precision processing requirements of the vacuum part.

[0014] 2. In the utility model, a triangular block is arranged under the lifting seat, and a triangular groove with a shape matching that of the clamp seat is opened on the top surface of the lifting seat. When the pneumatic punch press is working, its head contacts the lifting seat and drives the lifting seat to move downward along the limit column until the triangular block under the lifting seat docks with the triangular groove on the clamp seat. The lifting seat continues to move downward, and the triangular block drives the clamp seat to move toward the middle, providing driving force for the work of the clamp and reducing the cost of using the motor.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Figure 1-5 As shown, the utility model provides a pneumatic punching machine fixture for vacuum parts processing, including a lifting seat 1 and a base 6, the inner side wall of the base 6 is slidably connected to two clamp seats 7, the adjacent side walls of the two clamp seats 7 are fixedly connected with elastic pads 12, and the vacuum part is placed between the two clamp seats 7 for positioning processing, a processing punching groove 5 is opened at the center position of the top surface of the lifting seat 1, and the punching machine processes the vacuum part through the processing punching groove 5, the bottom end of the lifting seat 1 is fixedly connected to a triangular block 8, and the top surface of the clamp seat 7 is opened with a triangular groove 9 adapted to the shape of the triangular block 8.

[0024] The following is a detailed description of the specific settings and functions of this embodiment. This device is installed under the head of the pneumatic punch and placed above the carrier plate of the pneumatic punch. The pneumatic punch uses a cylinder as a driving part and uses the head to realize different processing methods such as single punching, continuous punching, and multi-directional punching on the processed parts. When punching, the two clamp seats 7 are moved toward each other to clamp and position the vacuum part. In order to avoid deformation caused by the mechanical clamp squeezing the vacuum part, an elastic pad 12 is installed on the clamping side of the two clamp seats 7. The elastic pad 12 is made of a flexible material with a certain toughness. When clamping with the vacuum part, the elastic pad 12 can fit perfectly. The uneven outer surface of the vacuum part is combined with the uneven outer surface of the vacuum part, thereby increasing the contact area with the vacuum part, avoiding the high-pressure deformation problem caused by single-point extrusion, and meeting the high-precision processing requirements of the vacuum part. When the pneumatic punching machine is working, its head contacts the lifting seat 1 and drives the lifting seat 1 to move downward along the limit column 2 until the triangular block 8 under the lifting seat 1 is docked with the triangular groove 9 on the fixture seat 7. The lifting seat 1 continues to move downward, which will allow the triangular block 8 to drive the fixture seat 7 to move toward the middle until the head is about to contact the surface of the vacuum part. The two fixture seats 7 position the vacuum part in the middle. Finally, the punching machine head passes through the processing punching slot 5 for processing.

[0025] Example 2: Figure 3 and Figure 5 As shown, a card slot 14 is provided on the inner bottom wall of the lifting seat 1, and a card rail 11 is fixedly connected to the bottom end of the clamp seat 7, and the card rail 11 is slidably connected to the elastic pad 12. A sealing plate 13 is provided above the top of the elastic pad 12, and the sealing plate 13 is connected to the clamp seat 7 by screws. The four corner positions of the lifting seat 1 are slidably connected to the limiting columns 2, and the limiting columns 2 are fixedly connected to the base 6. The outer wall of the clamp seat 7 is fixedly connected to the positioning shaft 10, and the positioning shaft 10 is slidably connected to the outer wall of the base 6. A spring 4 is provided on the outer wall of the positioning shaft 10, and one end of the positioning shaft 10 is fixedly connected to the baffle 3, one end of the spring 4 is fixedly connected to the baffle 3, and the other end of the spring 4 is fixedly connected to the outer wall of the base 6.

[0026] The effect achieved by the entire embodiment is that, after the vacuum part is completed, the pneumatic punch returns, so that the machine head is away from the surface of the lifting seat 1, so that the lifting seat 1 is no longer subjected to the pressure from above, and when the clamp seats 7 on both sides move toward the middle, the positioning shaft 10 is driven to move toward the inside of the base 6, so that the distance between the sealing plate 13 and the outer wall of the base 6 is shortened, so that the spring 4 is compressed. After the punch returns, the pressure of the spring 4 drives the sealing plate 13 to move outward, so that the sealing plate 13 drives the clamp seats 7 to move outward through the positioning shaft 10, so that the clamp seats 7 at both ends are gradually reset. When the clamp seats 7 move outward, the triangular groove 9 will move the inner The partially engaged triangular block 8 is pushed upward, so that the triangular block 8 drives the lifting seat 1 to move upward, and the lifting seat 1 is gradually reset for secondary punching processing. In order to enhance the reset effect of the lifting seat 1, a compression spring can be provided at the bottom end of the limit column 2. When the machine head leaves the lifting seat 1, the compression spring can be used to reset the lifting seat 1 alone without the help of the movement of the clamp seat 7. By providing a rail 11 under the clamp seat 7 and providing a slot 14 inside the base 6, the cooperation effect of the rail 11 and the slot 14 is utilized to guide the movement of the clamp seat 7, thereby ensuring the stability of the clamp.

[0027] The usage and working principle of this device: When the pneumatic punch press is working, the head of the pneumatic punch press contacts the lifting seat 1 and drives the lifting seat 1 to move downward along the limit column 2 until the triangular block 8 below the lifting seat 1 is docked with the triangular groove 9 on the clamp seat 7;

[0028] Then, the lifting seat 1 continues to move downward, the triangular block 8 drives the clamp seat 7 to move toward the middle, and drives the positioning shaft 10 to move toward the inside of the base 6, so that the distance between the sealing plate 13 and the outer wall of the base 6 is shortened, causing the spring 4 to be compressed. The two clamp seats 7 position the vacuum part in the middle, and the punch head passes through the processing punching slot 5 for processing.

[0029] After the processing is completed, the pneumatic punch head is away from the surface of the lifting seat 1, and the pressure of the spring 4 drives the closing plate 13 to move outward, so that the closing plate 13 drives the clamp seat 7 to move outward through the positioning shaft 10, allowing the clamp seats 7 at both ends to gradually reset. When the clamp seat 7 moves outward, the triangular groove 9 moves the internally engaged triangular block 8 upward, so that the triangular block 8 drives the lifting seat 1 to move upward and reset for secondary processing.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields.
