Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically to a pneumatic suction cup for processing thin-walled parts. Background Technology

[0002] Currently, for sealing components such as sealing housings, which are widely used in the hydraulic field, their high precision requirements and structural shape make them unsuitable for clamping with traditional fixtures. Furthermore, these components are thin-walled and require high surface quality, so traditional fixtures cannot meet their clamping needs. Finding machining datums for thin-walled components is also difficult. This inevitably leads to time and effort wasted in the mass production of these components, seriously affecting the production schedule of enterprises.

[0003] During the machining process, the cutting force between the tool and the part, the impact force of the coolant, and the adsorption force of the suction cup may interact, causing the part to shift position and thus affecting the accuracy of machining the part. To address these issues, the following solutions are proposed. Utility Model Content

[0004] The purpose of this invention is to provide a pneumatic suction cup for machining thin-walled parts, so as to solve at least one of the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic suction cup for processing thin-walled parts, including a base, and the base also includes a suction cup mechanism and a fixing mechanism;

[0006] A support column is fixedly connected to the top of the base, and a fixing block is fixedly connected to the top of the support column. A suction cup is fixedly connected to the side of the fixing block away from the support column. A through groove is opened on the top of the fixing block, and the through groove communicates with the support column.

[0007] Preferably, an electric telescopic rod is fixedly connected to the top of the base, and a circular suction plate is fixedly connected to the end of the electric telescopic rod away from the base. The outer wall of the circular suction plate is slidably connected to the inner wall of the support column.

[0008] Preferably, the bottom of the suction cup is fixedly connected to two support rods, and the ends of the two support rods away from the suction cup are respectively fixedly connected to a tray, and the top of the two trays are respectively provided with several sliding grooves.

[0009] Preferably, a slide rod is slidably connected to the inner wall of the slide groove, a clamping plate is fixedly connected to the top of the slide rod, and a strip plate is fixedly connected to the end of the slide rod away from the clamping plate.

[0010] Preferably, an annular block is fixedly connected to the outer wall of the support rod, a pulley is rotatably connected to the outer wall of the annular block, and a pull rope is fixedly connected to the outer wall of the strip plate, the pull rope passing around the pulley and slidingly connected to the pulley.

[0011] Preferably, a rectangular groove is provided on the outer wall of the support column, a connecting rod is fixedly connected to the bottom of the circular suction plate, the end of the connecting rod away from the circular suction plate extends to the outside of the rectangular groove and is slidably connected to the rectangular groove, a pull plate is fixedly connected to the extended end of the connecting rod, and the end of the pull plate away from the connecting rod is fixedly connected to the pull rope.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this utility model:

[0014] As the electric telescopic rod moves the circular suction plate downwards, the circular suction plate moves the connecting rod and the pull plate downwards. When the pull plate moves downwards, it pulls the strip plate inwards via the pull rope. After the strip plate moves, it moves the sliding rod and the clamping plate towards the part. With the simultaneous pulling of multiple pull ropes, the two clamping plates are forced to move closer to each other. After the two clamping plates move closer to each other, they can clamp and fix the part. Based on the suction cup adsorption of the part, the clamping plates can move towards the part to further clamp and fix the part from the side, realizing a multi-directional fixation method. Compared with simple suction cup adsorption, this design can better resist external forces from different directions, making the part more stable during processing. It ensures that the part can still maintain a stable state when subjected to large cutting forces or impact forces during processing, further ensuring processing accuracy.

[0015] When using this suction cup, place the part to be processed on top of the suction cup. At this time, a sealed space is formed between the part and the suction cup. Then, activate the electric telescopic rod. The electric telescopic rod drives the circular suction plate to move downward. After the circular suction plate moves downward, a negative pressure is generated between the part and the suction cup, thereby generating a strong suction force to firmly hold the part. This ensures that the part will not be displaced or shaken due to external forces or other factors during the processing, thus guaranteeing the accuracy and quality of the processing.

[0016] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] This utility model provides, for example Figure 1-4 The pneumatic suction cup shown is used for processing thin-walled parts. It includes a base 101, a suction cup mechanism 1 and a fixing mechanism 2. A support column 102 is fixedly connected to the top of the base 101. A fixing block 103 is fixedly connected to the top of the support column 102. A suction cup 104 is fixedly connected to the side of the fixing block 103 away from the support column 102. A through groove 105 is opened on the top of the fixing block 103 and communicates with the support column 102. An electric telescopic rod 106 is fixedly connected to the top of the base 101. A circular suction plate 107 is fixedly connected to the end of the electric telescopic rod 106 away from the base 101. The outer wall of the circular suction plate 107 is slidably connected to the inner wall of the support column 102.

[0025] When the device is needed, the part to be processed is first placed on top of the suction cup 104. At this time, a sealed space is formed between the part and the suction cup 104. Then, the electric telescopic rod 106 is activated. The electric telescopic rod 106 drives the circular suction plate 107 to move downward. After the circular suction plate 107 moves downward, a negative pressure is generated between the part and the suction cup 104, thereby generating a strong suction force to firmly hold the part in place. This ensures that the part will not be displaced or shaken due to external forces or other factors during the processing, thus guaranteeing the accuracy and quality of the processing.

[0026] Two support rods 201 are fixedly connected to the bottom of the suction cup 104. A support plate 202 is fixedly connected to the end of each support rod 201 away from the suction cup 104. Several sliding grooves 203 are formed on the top of each support plate 202. A sliding rod 204 is slidably connected to the inner wall of each groove 203. A clamping plate 205 is fixedly connected to the top of each sliding rod 204. A strip plate 206 is fixedly connected to the end of each sliding rod 204 away from the clamping plate 205. An annular block 207 is fixedly connected to the outer wall of the support rod 201. A rotating part is connected to the outer wall of the annular block 207. A pull rope 209 is fixedly connected to the outer wall of the pulley 208 and the strip plate 206. The pull rope 209 passes around the pulley 208 and is slidably connected to the pulley 208. A rectangular groove 210 is opened on the outer wall of the support column 102. A connecting rod 211 is fixedly connected to the bottom of the circular suction plate 107. The end of the connecting rod 211 away from the circular suction plate 107 extends to the outside of the rectangular groove 210 and is slidably connected to the rectangular groove 210. A pull plate 212 is fixedly connected to the extended end of the connecting rod 211. The end of the pull plate 212 away from the connecting rod 211 is fixedly connected to the pull rope 209.

[0027] As the electric telescopic rod 106 moves the circular suction plate 107 downward, the circular suction plate 107 moves the connecting rod 211 and the pull plate 212 downward. When the pull plate 212 moves downward, it pulls the strip plate 206 inward through the pull rope 209. After the strip plate 206 moves, it moves the sliding rod 204 and the clamping plate 205 towards the part. Under the simultaneous pull of multiple pull ropes 209, the two clamping plates 205 are forced to move closer to each other. After the two clamping plates 205 move closer to each other, they can clamp and fix the part. Based on the suction cup 104 adsorbing the part, the clamping plate 205 can move towards the part to further clamp and fix the part from the side, realizing a multi-directional fixing method. Compared with the simple suction cup 104 adsorption, this design can better resist external forces from different directions, making the part more stable during processing. It ensures that the part can still maintain a stable state when subjected to large cutting forces or impact forces during processing, further ensuring processing accuracy.

[0028] The working principle of the pneumatic suction cup for processing thin-walled parts provided by this utility model is as follows: When the suction cup needs to be used, the part to be processed is first placed on the top of the suction cup 104. At this time, a sealed space is formed between the part and the suction cup 104. Then, the electric telescopic rod 106 is activated. The electric telescopic rod 106 drives the circular suction plate 107 to move downward. After the circular suction plate 107 moves downward, a negative pressure is generated between the part and the suction cup 104, thereby generating a strong suction force to firmly hold the part.

[0029] As the electric telescopic rod 106 moves the circular suction plate 107 downward, the circular suction plate 107 moves the connecting rod 211 and the pull plate 212 downward. When the pull plate 212 moves downward, it pulls the strip plate 206 inward through the pull rope 209. After the strip plate 206 moves, it drives the sliding rod 204 and the clamping plate 205 to move towards the part. Under the simultaneous pull of multiple pull ropes 209, the two clamping plates 205 are forced to move closer to each other. After the two clamping plates 205 move closer to each other, they can clamp and fix the part.

After the strip plate 206 moves, it moves the sliding rod 204 and the clamping plate 205 towards the part. Under the simultaneous pull of multiple pull ropes 209, the two clamping plates 205 are forced to move closer to each other.
