Description

TECHNICAL FIELD

[0001] The utility model relates to the field of sheet metal processing especially a general fixture for sheet metal part machining. BACKGROUND

[0002] In the field of sheet metal part machining, the use of fixtures is crucial to ensure machining precision and efficiency. With the rapid development of modern industry, the types of sheet metal parts are increasingly diverse, with significant differences in shape and size, including various irregular shapes and sheet metals of different thicknesses.

[0003] Currently, the existing sheet metal part fixtures on the market have many limitations. On the one hand, fixtures for specific shapes of sheet metal parts have very poor versatility. For example, a fixture for fixing square sheet metal parts cannot effectively fix circular or triangular sheet metal parts of other shapes. This results in the need for a large number of different types of special fixtures in production environments that process multiple types of sheet metal parts, increasing production costs and the complexity of fixture storage and management.

[0004] On the other hand, existing fixtures have limited adjustment range for sheet metal parts of different sizes. Many fixtures can only fix sheet metal parts within a small size range. When the size of the sheet metal part exceeds this range, it cannot be fixed or is not fixed securely, affecting the processing quality. For example, in automobile manufacturing, the sizes of body sheet metal parts vary widely, from small parts to large body side panels, and traditional fixtures cannot meet the demand for such extensive size variations. SUMMARY

[0005] To improve the versatility of sheet metal fixtures, the utility model provides a general fixture for sheet metal part machining.

[0011] Optionally, the clamping mechanism further comprises an elastic member, which is arranged at the bottom end of the clamping plate.

[0012] By adopting the above technical scheme, when the workpiece is clamped, the top end of the workpiece is first in abutment with the elastic member, which reduces the possibility of impact caused by direct contact between the clamping plate and the workpiece, and protects the workpiece.

[0013] Optionally, the clamping mechanism further comprises a pressing plate, one end of which is fixedly connected with the elastic member.

[0014] By adopting the above technical scheme, the pressing plate first contacts the workpiece, which increases the contact area and further reduces the damage to the workpiece while improving the clamping stability of the workpiece.

[0015] Optionally, the clamping mechanism further comprises a pressure sensor, which is arranged at the bottom end of the pressing plate.

[0016] By adopting the above technical scheme, the pressure sensor detects the clamping force between the clamping seat and the clamping plate in real time, and if the clamping pressure is not within the normal range, the worker is reminded to correct the clamping position.

[0017] Optionally, the clamping mechanism is provided with two groups on the adjusting rod; the clamping mechanism further comprises a connecting assembly, the connecting assembly comprising a rotating disc and a connecting rod, the rotating disc being rotationally arranged on the adjusting rod between the two groups of clamping mechanisms, one end of the connecting rod being hingedly connected with the rotating disc, the other end of the connecting rod being hingedly connected with the bottom end of the slide, and two connecting rods are arranged on one rotating disc.

[0018] By adopting the above technical scheme, when the telescopic cylinder drives the clamping plates to rotate, the telescopic cylinder drives two clamping plates to rotate simultaneously through the connecting assembly, multi-point clamping of the workpiece is realized, and different sizes and shapes of workpieces can be clamped, so that the clamping range and flexibility of the device are improved.

[0019] Optionally, the clamping mechanism further comprises a buffer layer, and the buffer layer is arranged at the top end of the clamping seat.

[0020] By adopting the above technical scheme, the buffer layer can play a buffering role to reduce the damage of the workpiece when the workpiece is placed.

[0022] By adopting the above technical scheme, the range of multi-point clamping is further expanded, and the universality of clamping of the device is further improved.

[0023] Optionally, a controller is arranged on the rack, and the controller is electrically connected with the telescopic cylinder and the pressure sensor.
