Description

Technical Field

[0001] This utility model relates to the field of flexible clamping technology, and in particular to a flexible clamping assembly. Background Technology

[0002] Currently, in the field of material clamping, flexible grippers are a type of clamp used to hold materials. These grippers are made of flexible materials and utilize air pressure to drive the fingers of the flexible grippers to bend, achieving flexible clamping. The conventional method for fixing flexible grippers is to mount the gripper on a mounting base, which is then fixed to a support. For example, patent announcement number CN208854651U discloses a flexible fabric gripping device, which fixes several grippers to a mounting base, which is then fixed to a support. This results in a relatively large mounting bracket portion for the flexible gripper, requiring a significant amount of space at the top. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a flexible clamping assembly that facilitates the series installation of flexible grippers, simplifies the structure as much as possible, and reduces the space occupied above.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a flexible clamping assembly, including a connector and a plurality of flexible grippers. The connector is a rectangular profile connector, which includes an axially penetrating air passage. The air passage is located near one side of the profile connector. At least one of the other three sides of the profile connector is provided with a tapered connecting groove. The profile connector is provided with a plurality of mounting holes communicating with the air passage. An air passage connector is threaded into the mounting hole. An air passage master connector is threaded into one end of the air passage, and a plug is threaded into the other end of the air passage. A flexible clamp is connected to the end of the air passage connector. The air passage connector and the mounting hole, and the air passage connector and the flexible clamp are sealed by a sealing ring.

[0005] As a preferred embodiment, the connecting grooves are provided on the other three sides of the profile connector.

[0006] As a preferred embodiment, the profile connector is provided with screw connection holes near the four corners.

[0007] As a preferred embodiment, the profile connector is also provided with axially extending weight-reducing hollow holes.

[0008] As a preferred embodiment, the weight-reducing hollow hole is located in the middle of the profile connector, and the weight-reducing hollow hole includes a connecting groove that matches the shape of the three sides and the air passage.

[0009] As a preferred embodiment, the end of the profile connector is further fixed with an end cap that seals the plug.

[0010] As a preferred embodiment, the end cap includes an end cap body, which is further provided with at least one insertion protrusion for inserting into the screw connection hole and at least one connection hole corresponding to the screw connection hole, and a connection screw is threadedly installed between the connection hole and the screw connection hole.

[0011] As a preferred embodiment, a receiving recess is provided on the side of the end cap body near the profile connector, and the receiving recess corresponds to the position of the plug to accommodate the plug.

[0012] After adopting the above technical solution, the effect of this utility model is as follows: The flexible clamp assembly includes a connector and several flexible grippers. The connector is a rectangular profile connector, which includes an axially penetrating air passage. The air passage is located near one side of the profile connector. At least one of the other three sides of the profile connector is provided with a tapered connecting groove. The profile connector has several mounting holes communicating with the air passage. Air connectors are threaded into the mounting holes. An air master connector is threaded into one end of the air passage, and a plug is threaded into the other end of the air passage. The air connector... The end is connected to a flexible gripper. The air passage connector and the mounting hole, as well as the air passage connector and the flexible gripper, are sealed by sealing rings. Therefore, this flexible clamping assembly directly uses the profile connector to fix the flexible gripper. The air passage of the profile is used as the main drive air passage, and then the air passage connector drives the clamping action of the flexible gripper. Therefore, this flexible clamping assembly only uses the profile connector to install the flexible gripper. There is more space above the flexible gripper, making it more convenient to use. At the same time, the profile connector is provided with a connecting groove. It is only necessary to embed a sliding nut in the connecting groove and then fix the profile connector to the end of the robot arm with bolts.

[0013] Furthermore, since the connecting grooves are provided on the other three sides of the profile connector, different connecting grooves can be selected for connection according to the actual installation method, making it more practical.

[0014] Furthermore, the profile connector is also provided with axially extending weight-reducing perforated holes. These perforated holes are located in the middle of the profile connector and include fitting sections that adapt to the shapes of the connecting grooves on the three sides and the air passage. Therefore, these perforated holes can better adapt to other connecting grooves, allowing for a larger perforated area and a lower profile weight.

[0015] Furthermore, since the end of the profile connector is also fixed with an end cap that seals the plug, the end cap can effectively protect the plug and prevent the plug from colliding with other parts.

[0016] Furthermore, since the end cap includes an end cap body, and the end cap body is also provided with at least one insertion protrusion for inserting into the screw connection hole and at least one connection hole corresponding to the screw connection hole, and a connection screw is threaded between the connection hole and the screw connection hole, the end cap can be inserted and positioned by the insertion protrusion, and then the connection screw can be screwed into the connection hole for locking and fixing.

[0017] Furthermore, since a receiving recess is provided on the side of the end cap body near the profile connector, the receiving recess corresponds to the position of the plug and accommodates the plug. The receiving recess can be used to conveniently accommodate the plug, so the thickness of the end cap can be reduced. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described in detail below through specific embodiments.

[0026] like Figure 1-5As shown, a flexible clamping assembly includes a connector and several flexible grippers. The connector is a rectangular profile connector 1, which includes an axially penetrating air passage 2. The air passage 2 is located near one side of the profile connector 1. At least one of the other three sides of the profile connector 1 is also provided with a tapered connecting groove 3. The profile connector 1 is provided with several mounting holes 4 communicating with the air passage 2. An air passage connector 5 is threaded into the mounting holes 4. An air passage master connector 6 is threaded into one end of the air passage 2, and a plug 7 is threaded into the other end of the air passage 2. A flexible clamp 8 is connected to the end of the air passage connector 5. The air passage connector 5 and the mounting holes 4, and the air passage connector 5 and the flexible clamp 8 are sealed by sealing rings.

[0027] In this embodiment, the connecting grooves 3 are provided on the other three sides of the profile connector 1. Screw connection holes 9 are provided near the four corners of the profile connector 1. The profile connector 1 also has axially extending weight-reducing perforated holes 10. The weight-reducing perforated holes 10 are located in the middle of the profile connector 1, and include fitting sections 101 that are adapted to the shapes of the connecting grooves 3 on the three sides and the air passage 2.

[0028] In this embodiment, the end of the profile connector 1 is further fixed with an end cap 11 that seals the plug 7. The end cap 11 includes an end cap body 111, which is provided with at least one insertion protrusion 112 for inserting into the screw connection hole 9 and at least one connection hole 113 corresponding to the screw connection hole 9. A connecting screw is threaded between the connection hole 113 and the screw connection hole 9. A receiving recess 114 is provided on the side of the end cap body 111 near the profile connector 1, and the receiving recess 114 corresponds to the position of the plug 7 to accommodate the plug 7.

[0029] The flexible clamp assembly of this application directly utilizes the profile connector 1 to fix the flexible gripper.

The flexible clamp assembly of this application only uses the space of the profile connector 1 to install the flexible gripper, without the need for additional space, which simplifies the original support structure. The space above the flexible gripper is more abundant and easier to use. At the same time, the other three sides of the profile connector 1 are provided with connecting grooves 3, and also with adapter sections 101 of weight-reducing hollow holes 10, which can better fit the connecting grooves 3. Different connecting grooves 3 on the profile connector 1 can be selected for connection according to the actual installation method. It is only necessary to embed a sliding nut in the connecting groove 3, and then fix the profile connector 1 to the end of the robot with bolts.
