Description

Technical Field

[0001] The utility model relates to the technical field of flexible jigs, and particularly relates to a multi-functional flexible jig mounting base. Background Art

[0002] A flexible jig uses elastic materials to grasp soft and fragile objects without damaging the objects themselves. The main types of flexible jigs are flexible jigs composed of flexible fingers or flexible jigs composed of flexible jaws. For example, a published document with the publication number CN219748045U discloses a flexible jaw, and a published document with the publication number CN207027538U discloses a flexible manipulator composed of flexible fingers. At present, due to the different installation methods of these two types of flexible jigs, different mounting bases are required to be fixedly installed on the robotic arm. Therefore, the types of mounting bases are relatively many, the installation is relatively complex, and the mold opening cost is relatively high. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a multi-functional flexible jig mounting base, which can be suitable for the fixed installation between a variety of flexible jigs and the robotic arm.

[0004] To solve the above technical problem, the technical solution of the utility model is: a multi-functional flexible jig mounting base, including a seat body. A gas path distribution chamber is arranged on the seat body. A total air inlet / outlet, a side air inlet / outlet and a central air inlet / outlet are arranged on the seat body. The side air inlet / outlet is located on the side of the central air inlet / outlet. The total air inlet / outlet, the side air inlet / outlet and the central air inlet / outlet are all communicated with the gas path distribution chamber. The side air inlet / outlet is used to be communicated with the air path of the flexible finger. The central air inlet / outlet is used to be communicated with the air path of the flexible jaw. A fixing structure for facilitating fixation on the robotic arm mounting shaft is arranged at the upper end of the seat body. A jaw connecting structure for facilitating connection with the flexible jaw or a finger connecting structure for facilitating connection with the flexible finger mounting plate is arranged on the seat body.

[0005] As a preferred solution, the fixing structure includes a hoop fixed at the upper end of the seat body. A tightening hole for facilitating the insertion of the robotic arm mounting shaft is arranged on the hoop. A locking bolt for locking the robotic arm mounting shaft is arranged on the hoop.

[0006] As a preferred solution, the jaw connecting structure includes a connecting threaded hole communicated with the central air inlet / outlet. A jaw air path connecting head is threadedly connected to the connecting threaded hole. The jaw air path connecting head is connected with the flexible jaw and communicates the inner cavity of the flexible jaw and the air path of the central air inlet / outlet.

[0007] As a preferred solution, the connecting threaded hole is concentrically arranged with the central air inlet / outlet.

[0008] As a preferred solution, the finger connection structure further includes at least two finger connection screw holes provided on the base body. Finger connection bolts are installed in the finger connection screw holes, and the base body is connected to the flexible finger mounting plate through the finger connection bolts.

[0009] As a preferred solution, the finger connection screw holes penetrate the base body vertically.

[0010] As a preferred solution, a positioning sunk groove for positioning and mating with the robotic arm mounting shaft is further provided at the upper end of the base body.

[0011] As a preferred solution, the hoop is detachably fixed to the upper end of the base body, and the number of the positioning sunk grooves is multiple and they are concentrically arranged.

[0012] After adopting the above technical solutions, the effects of the present utility model are as follows: Since a multifunctional flexible fixture mounting base includes a base body, an air path distribution chamber is provided on the base body, a total air inlet / outlet, side air inlet / outlets and a central air inlet / outlet are provided on the base body, the side air inlet / outlets are located on the sides of the central air inlet / outlet, the total air inlet / outlet, the side air inlet / outlets and the central air inlet / outlet are all communicated with the air path distribution chamber, the side air inlet / outlets are used for communicating with the flexible finger air path, the central air inlet / outlet is used for communicating with the flexible jaw air path, a fixing structure for facilitating fixation on the robotic arm mounting shaft is provided at the upper end of the base body, a jaw connection structure for facilitating connection with the flexible jaw or a finger connection structure for facilitating connection with the flexible finger mounting plate is provided on the base body. Therefore, when using the flexible finger as a fixture, only the central air inlet / outlet needs to be directly blocked, the flexible finger mounting plate is directly fixed on the base body through the finger connection structure, and the air path of the flexible finger is docked and communicated with the side air inlet / outlets, and the upper end of the base body is fixed on the robotic arm mounting shaft through the fixing structure, so as to finally complete the fixed installation of the flexible finger fixture; when using the flexible jaw as a fixture, at this time the side air inlet / outlets are blocked, the top of the flexible jaw is fixed on the base body through the jaw connection structure, the central air inlet / outlet is communicated with the flexible jaw, and the total air inlet / outlet is communicated with the total driving air path component. From the above structure, it can be seen that this mounting base can complete the fixed installation of two types of flexible fixtures, namely flexible jaws and flexible fingers, with stronger adaptability, saving the mold opening cost and reducing the cost.

[0013] Also, since the fixing structure includes a hoop fixed to the upper end of the base body, a tightening hole for facilitating the insertion of the robotic arm mounting shaft is provided on the hoop, and a locking bolt for locking the robotic arm mounting shaft is provided on the hoop. Therefore, the hoop can be tightened on the robotic arm mounting shaft through the locking bolt on the hoop, and then the entire mounting base is fixed on the robotic arm, and the fixing is simple.

[0014] Also, since the jaw connection structure includes a connection threaded hole communicating with the central air inlet / outlet, a jaw air path connector is threadedly connected to the connection threaded hole. The jaw air path connector is connected to the flexible jaw and connects the inner cavity of the flexible jaw and the air path of the central air inlet / outlet. Therefore, by directly threadedly connecting the jaw air path connector to the connection threaded hole, the flexible jaw can be directly fixed to the seat body, not only completing the connection but also completing the connection of the air path, and the fixation is simple and convenient.

[0015] Also, since a positioning sunk groove for positioning and mating with the robotic arm mounting shaft is provided at the upper end of the seat body, this positioning sunk groove can perform positioning and mating with the robotic arm mounting shaft to ensure that the installation accuracy between the entire mounting seat and the robotic arm mounting shaft meets the requirements.

[0016] Also, since the hoop is detachably fixed to the upper end of the seat body, and the number of the positioning sunk grooves is multiple and they are concentrically arranged, in this way, it can meet the positioning and mating of different robotic arm mounting shafts. And since the hoop is detachably fixed to the upper end of the seat body, therefore, by replacing hoops of different sizes, the clamping and fixing of robotic arm mounting shafts of different sizes can be satisfied.
