Description

Technical Field

[0001] This utility model relates to the field of suction cup tooling technology, and in particular to a suction cup clamping and positioning tooling. Background Technology

[0002] Clamping and positioning fixtures are used to accurately position and firmly clamp workpieces, ensuring that the workpieces maintain a stable position and posture during processing. By using clamping and positioning fixtures, processing accuracy can be effectively improved, product quality consistency can be guaranteed, production efficiency can be increased, and production costs can be reduced.

[0003] The suction cup clamping and positioning fixture uses the suction force generated by the suction cup to clamp and position the workpiece. It is especially suitable for some workpieces with relatively flat and smooth surfaces. The suction cup clamping and positioning fixture can achieve quick clamping, reduce clamping time, and because it adopts a non-contact and soft contact clamping method, it can avoid scratches and damage to the workpiece surface.

[0004] Current suction cup clamping and positioning fixtures use manual lead screws and rack and pinion structures for adjustment, which are cumbersome to operate, time-consuming to adjust, and have poor positioning accuracy, failing to meet the requirements of high-precision machining. Existing technology introduces electric servo adjustment systems, combined with ball screws and linear guides, to achieve automated and high-precision adjustment. Operators only need to input workpiece size parameters on the control panel to quickly complete the fixture adjustment. However, when dealing with irregularly shaped workpieces, uneven negative pressure distribution can prevent clamping, thus affecting work efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a suction cup clamping and positioning fixture, which aims to improve the problem in the prior art that when dealing with irregularly shaped workpieces, the uneven distribution of negative pressure makes clamping impossible, thus affecting work efficiency.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, an external air extraction device performs air extraction. The bottoms of multiple air extraction slots are all connected to the spiral groove. After the air in the spiral groove is extracted, a negative pressure environment is formed between the suction cup and the object being adsorbed. The suction cup is tightly adsorbed onto the surface of the object being adsorbed. The design of the spiral groove being connected to multiple air extraction slots and ventilation slots can make the negative pressure more evenly distributed on the contact surface between the suction cup and workpieces of different shapes, enhancing the adsorption effect, thereby realizing the clamping and positioning of workpieces of different shapes.

[0031] 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.

[0032] Reference Figure 3 , Figure 4 and Figure 5 An embodiment of this utility model provides a suction cup clamping and positioning fixture, including a positioning plate 1. A suction cup groove 11 is provided on the front top of the positioning plate 1. A spiral groove 3 is provided on the bottom of the inner wall of the suction cup groove 11. A ventilation groove 4 is provided on the inner wall of the spiral groove 3. A ventilation port 5 is fixedly connected to the front side of the ventilation groove 4. A suction pipe 6 is fixedly connected to the other end of the ventilation port 5. A second suction pipe 7 is provided at the other end of the first suction pipe 6. An air valve 8 is fixedly connected to the middle of the second suction pipe 7. A suction cup 9 is fixedly connected to the inner wall of the suction cup groove 11. A plurality of suction grooves 10 are provided on the top of the suction cup 9. The bottom of the plurality of suction grooves 10 is connected to the spiral groove 3. A moving mechanism 2 is provided at the bottom of the positioning plate 1. The moving mechanism 2 is used to move the suction cup clamping and positioning fixture.

[0033] Specifically, when using the suction cup clamping and positioning fixture, first open the air valve 8. The external air extraction device extracts air from the spiral groove 3 through the second suction pipe 7 and the first suction pipe 6, and through the air vent 5 and the air vent 4. Since the bottoms of the multiple suction vents 10 are all connected to the spiral groove 3, after the air in the spiral groove 3 is extracted, a negative pressure environment is formed between the suction cup 9 and the object being adsorbed. Under the action of atmospheric pressure, the suction cup 9 is tightly adsorbed onto the surface of the object being adsorbed. The connection design between the spiral groove 3 and the multiple suction vents 10 and the air vent 4 can make the negative pressure more evenly distributed on the contact surface between the suction cup 9 and the workpieces of different shapes, enhancing the adsorption effect, thereby realizing the clamping and positioning of workpieces of different shapes.

[0034] Reference Figure 1 and Figure 2The moving mechanism 2 includes a worktable 201, which is located at the bottom of the positioning disk 1. The top and front sides of the worktable 201 are fixedly connected to connecting plates 208. Two support columns 203 are fixedly connected to the four corners of the bottom of the positioning disk 1. The bottom of the multiple support columns 203 is rotatably connected to a rotating wheel 202. The multiple rotating wheels 202 are rotatably connected to the corresponding connecting plates 208. One side of the multiple rotating wheels 202 is fixedly connected to a corresponding rotating shaft 204. A passive bevel gear 205 is fixedly connected to the outer wall of the right rotating shaft 204. A motor 206 is fixedly connected to the bottom of the positioning disk 1. An active bevel gear 207 is fixedly connected to the output end of the motor 206. The active bevel gear 207 and the passive bevel gear 205 are meshed together.

[0035] Specifically, when the suction cup clamping and positioning fixture needs to be operated, the motor 206 is started. The output shaft of the motor 206 drives the active bevel gear 207 to rotate. Since the active bevel gear 207 is meshed with the passive bevel gear 205, the passive bevel gear 205 will rotate accordingly. The passive bevel gear 205 is fixed on the rotating shaft 204, which in turn drives the rotating shaft 204 to rotate. The rotating shaft 204 is fixedly connected to the rotating wheel 202. The rotating wheel 202 starts to rotate, which in turn drives the positioning disk 1 to move, so that the positioning fixture can move flexibly on the worktable 201. The operator can easily adjust the position of the fixture according to the actual processing operation requirements, without the need for manual handling of the positioning disk 1, saving manpower and improving the convenience of operation, further improving the overall work efficiency.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The other end of the suction pipe 6 is fixedly connected to a filter 12. The front side of the filter 12 is fixedly connected to one end of the suction pipe 7 to filter out impurities and dust in the gas. The top of the two connecting plates 208 is provided with a limit groove 13. Multiple rotating wheels 202 are connected to rotate inside the corresponding limit groove 13. The limit groove 13 restricts the movement range of the rotating wheels 202. The top of the suction cup 9 is fixedly connected to a protective sleeve 14. The protective sleeve 14 is made of sponge material and plays a buffering role when clamping objects. The top of the suction cup 9 is fixedly connected to a sealing ring 15. The bottom of the sealing ring 15 is fixedly connected to the top of the positioning plate 1. The top of the positioning plate 1 is fixedly connected to multiple positioning protrusions 16. The multiple positioning protrusions 16 are all made of stainless steel. The top left side of the worktable 201 is fixedly connected to a controller 17. The controller 17 is electrically connected to the air valve 8 and the motor 206 respectively to realize automated operation and improve the accuracy and convenience of operation.

[0037] Specifically, the filter 12 installed between suction pipe 6 and suction pipe 7 can effectively filter impurities and dust in the extracted gas, preventing these impurities from entering the extraction system, ensuring gas purity, and extending the service life of the air valve 8 and the extraction equipment. The limiting groove 13 restricts the movement range of the rotating wheel 202, preventing the positioning plate 1 from detaching from the worktable 201 during movement, ensuring the safety of equipment operation. The sponge protective sleeve 14 on the top of suction cup 9 can act as a buffer when clamping objects, preventing suction cup 9 from directly contacting the object surface and causing scratches and wear damage. The sealing rings 15 around the top of suction cup 9 enhance the sealing between suction cup 9 and the object being adsorbed, improving the adsorption effect. The controller 17 is electrically connected to the air valve 8 and the motor 206 respectively. The operator can centrally control the adsorption and movement functions of the tooling through the controller 17 to achieve automated operation and improve the accuracy and convenience of operation.

[0038] Working principle: When using the suction cup clamping and positioning fixture, first open the air valve 8. The external air extraction device extracts air from the spiral groove 3 through the second suction pipe 7 and the first suction pipe 6, and through the air port 5 and the air groove 4. Since the bottoms of the multiple suction grooves 10 are all connected to the spiral groove 3, after the air in the spiral groove 3 is extracted, a negative pressure environment is formed between the suction cup 9 and the object being adsorbed. Under the action of atmospheric pressure, the suction cup 9 is tightly adsorbed onto the surface of the object being adsorbed. The connection design between the spiral groove 3 and the multiple suction grooves 10 and the air groove 4 can make the negative pressure more evenly distributed on the contact surface between the suction cup 9 and the workpieces of different shapes, enhancing the adsorption effect, thereby realizing the clamping and positioning of workpieces of different shapes.

[0039] Furthermore, when the suction cup clamping and positioning fixture needs to be operated, the motor 206 is started. The output shaft of the motor 206 drives the active bevel gear 207 to rotate. Since the active bevel gear 207 is meshed with the passive bevel gear 205, the passive bevel gear 205 will rotate accordingly. The passive bevel gear 205 is fixed on the rotating shaft 204, which in turn drives the rotating shaft 204 to rotate. The rotating shaft 204 is fixedly connected to the rotating wheel 202, which starts to rotate, thereby driving the positioning disk 1 to move. This allows the positioning fixture to move flexibly on the worktable 201. The operator can easily adjust the position of the fixture according to the actual processing requirements without manually moving the positioning disk 1, saving manpower and improving the convenience of operation, further enhancing the overall work efficiency.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
