Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:

as shown in the figure, the pen head clamp is used for the operation of a workstation of a pen head on a painting brush automatic production line.

The mechanical part of the pen consists of a mounting seat 1, a finger cylinder 2 and a pen point clamping mechanism. The finger cylinder 1 is fixedly installed on the installation seat 2 through screws, and the installation seat 2 is installed on a moving device of an automatic machine, so that conversion between stations is realized. The pen point clamping mechanism is arranged on a pair of clamping jaws 3 of the finger cylinder, the clamping mechanism in the technical scheme comprises a pair of connecting claws 4 and a pair of clamping blocks 5, the connecting claws 4 are fixedly arranged on the outer sides of the clamping jaws 3 respectively through screws, and the clamping jaws 3 are driven to complete opening and closing actions. The connecting claw 4 extends outwards along the length direction of the finger cylinder, so that a sufficient grabbing space is provided. The pair of clamping blocks 5 are respectively arranged on the opposite inner walls of the extending sections of the pair of connecting claws 4, the opposite side surfaces of the pair of clamping blocks 5 are respectively provided with a half-hole clamping groove 6 which vertically penetrates through, and the half-hole clamping groove 6 is vertical to the moving direction of the clamping jaw 3; when the clamping jaws of the finger cylinder 1 are closed, the pair of clamping blocks 3 move oppositely and are in contact fit, and the two half-hole clamping grooves 6 form a cylindrical clamping cavity 7 matched with the outer contour surface of the pen point to clamp the pen point. In order to avoid damage to the pen head, the clamping block 5 is made of rubber or acrylic. A spring 8 is arranged between the pair of connecting claws 4, the spring 8 is arranged along the opening and closing direction of the clamping jaw, and the opened clamping block can be conveniently reset quickly to clamp the pen point. Because the connecting claw 4 and the clamping block 5 have certain weight, in order to avoid damaging the clamping jaw 3 of the finger cylinder 1, a linear track 9 can be arranged at the end part of the finger cylinder 1 along the opening and closing direction of the clamping jaw 3, the end part of the connecting claw 4 is fixed with a sliding block 10 on the track 9, and the pressure of the clamping jaw 3 in the vertical direction is reduced.

The pneumatic control part comprises a telescopic cylinder 11, an air nozzle 12 and an air nozzle butt joint seat 13. The telescopic cylinder 11 is vertically suspended right above the finger cylinder 1 and is fixed on the mounting seat 2 or a workbench of a work station by a bracket 14. The telescopic cylinder 11 is preferably a pneumatic telescopic cylinder. The telescopic rod of the telescopic cylinder 11 is arranged downwards, and the air tap 12 is arranged at the end part of the telescopic rod of the telescopic cylinder. The air tap 12 is a tapered cavity, the side wall of the air tap 12 is connected with high-pressure air through a pipeline, the bottom of the air tap 12 is a conical head 15, and the head of the conical head 15 is provided with an opening for air outlet. The air tap butt joint seat 13 is installed on the top surface of the finger cylinder 1, a vertical through channel communicated with an air inlet of the finger cylinder is arranged in the air tap butt joint seat 13, a lower opening of the channel is communicated with the air inlet of the finger cylinder 1, and an upper opening of the channel is a conical opening 16 matched with a conical head of the air tap. In order to avoid air leakage, the air nozzle docking seat 13 may be made of rubber or acrylic. A channel communicated with the finger cylinder after air return is further processed in the air nozzle butt joint seat 13, and the tail end of the channel is connected with an air return pipe.
