SUMMERY OF THE UTILITY MODEL

The utility model discloses the technical problem that will solve is: the existing mechanical gripper module is single, and multiple structures are needed for realizing multiple functions.

In order to solve the technical problem, the utility model discloses a technical scheme be: the pressing mechanism comprises a base, a first claw, a second claw and a pressing mechanism, wherein the first claw, the second claw and the pressing mechanism are detachably connected to the base.

Furthermore, the base comprises a Y-shaped fixed seat and a quick-change device, and the quick-change device is connected with the Y-shaped fixed seat.

Furthermore, the quick-change device is connected to a mechanical arm, and the mechanical arm drives the quick-change device to move, so as to drive the Y-shaped fixing seat to move.

Furthermore, three support arms of the Y-shaped fixing seat are respectively connected with the first paw, the second paw and the pressing mechanism.

Furthermore, the first paw, the second paw and the pressing mechanism are arranged at an included angle of 120 degrees.

Furthermore, the first paw and the second paw are respectively connected to a paw driving mechanism, and the paw driving mechanism is used for driving the first paw and the second paw to open and close.

Further, the paw driving mechanism is an air cylinder.

The beneficial effects of the utility model reside in that: a plurality of functions can be realized through the independent mechanism of an electrode quick change hand claw, and a mechanism is provided with three independent modules which are connected with a Y-shaped fixed seat to realize different functions respectively.

The same reference numbers in all figures indicate similar or corresponding features or functions.

In the figure: 1-a first paw, 2-a second small paw, 3-a Y-shaped fixed seat, 4-a quick-change device and 5-a pressing mechanism.

Detailed Description

In order to explain technical contents, structural features, and objects and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

Example 1

Referring to fig. 1, a base, a first gripper 1, a second gripper 2 and a pressing mechanism 5 detachably connected to the base. The three mechanisms realize the effect that different modules are arranged on one mechanism to realize different functions. The base comprises a Y-shaped fixing seat 3 and a quick-change device 4, as shown in the figure, the quick-change device 4 is connected to the Y-shaped fixing seat, and the round device at the top of the Y-shaped fixing seat 3 is the quick-change device 4. The Y-shaped fixed seat 3 comprises three support arms which are arranged at a certain angle, and the three support arms are respectively connected with the first claw 1, the second claw 2 and the pressing mechanism 5. In this embodiment, the first gripper 1, the second gripper 2 and the pressing mechanism 5 are arranged at an included angle of 120 degrees, so that each module can more independently complete a corresponding function. The first paw 1 and the second paw 2 drive the first paw 1 and the second paw 2 to open and close through paw driving mechanisms, the paw driving mechanisms are cylinders, the first paw 1 is used for clamping electrode blanks, and the second paw 2 is used for clamping electrode bases. The pressing mechanism 5 is connected with the Y-shaped fixed seat 3, and the pressing mechanism 5 is used for pressing the blank and centering the blank twice. The pressing mechanism 5 has two cylinders, one is used for the cylinder that compresses tightly, and the other is used for the cylinder that centers on. The tail end of the pressing cylinder is connected with a rolling ball, and the blank is pressed through point contact; the cylinder placed in the middle adopts revolving cylinder, through end-to-end connection rack and pinion, cylinder end-to-end connection's gear, the rack is installed respectively in both sides, realizes opening and closing of great stroke through just reversing, because both sides rack and same gear cooperation, so the stroke that the rack removed is unanimous, can reach the effect placed in the middle.

The quick-change device 4 is connected with a mechanical arm, the electrode gripper is connected with the quick-change device 4 in the working process, the mechanical arm drives the quick-change device 4 to rotate, and then the Y-shaped fixing seat 3 connected with the quick-change device 4 is driven to rotate, so that the first gripper 1, the second gripper 2 and the pressing mechanism 5 are conveyed to different stations. The gripper driving mechanism drives the gripper to open and close, the first gripper 1 clamps the blank, the second gripper 2 clamps the electrode base, the mechanical arm rotates to drive the quick-change device 4 and the Y-shaped fixing seat 3 to rotate, the electrode base is placed at a specified clamping position, the blank is placed in an electrode base groove, and the pressing mechanism 5 moves to the station and then compresses the blank and performs secondary centering positioning of the blank on the electrode base.

From the above description, the beneficial effects of the present invention are: a plurality of functions can be realized through an independent mechanism of an electrode quick-change paw, three independent modules are arranged on one mechanism and are connected with a Y-shaped fixed seat, different functions are realized respectively, and each module can also independently realize corresponding functions.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
