Abstract
The invention relates to a clamp, in particular to a latch of a PCB plate clamp which is provided with an upper locking block and a lower locking block; the upper locking block is elastically and movably connected with an upper pressure pad on the PCB plate clamp; the lower locking block is fixedly connected with a lower pressure pad on the PCB plate clamp; an air cylinder is fixed on the lower pressure pad; when the upper locking block and the lower locking block are engaged and locked, a top rod of the air cylinder is sustained with the lower locking block when the top rod of the air cylinder extends out; the catering surface of the upper locking block and the lower locking block is an incline; the incline angle Alpha of the incline is 30 degrees; the latch of the PCB plate clamp of the invention has simple structure, can conveniently realize the opening and closing of the PCB plate clamp and improves the working efficiency; simultaneously, the clamp of the invention is stable and reliable when the PCB plate clamp is in locking state , thus ensuring the welding quality of the PCB plate.
Description
Technical field
The present invention relates to a kind of anchor clamps, especially a kind of pcb board anchor clamps snap close.
Background technology
Pcb board needs to be gripped in welding process, to keep static relatively, guarantees welding quality.The fixed form of pcb board is had multiple, or adopt manual fixing mode, inefficiency is unfavorable for large-scale pipeline production, or adopts mechanical type to fix, but the structure relative complex, has increased manufacturing cost is set.
Summary of the invention
In order to realize that pcb board is carried out fixing quickly and easily, the invention provides a kind of pcb board anchor clamps snap close.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pcb board anchor clamps snap close, have last lock dog and following lock dog, top board elasticity on last lock dog and the pcb board anchor clamps flexibly connects, following lock dog is fixedlyed connected with the lower platen on the pcb board anchor clamps, on lower platen, be set with cylinder, when last lock dog and following lock dog snap-lock, when stretching out, the push rod of cylinder offsets with following lock dog.
Particularly: go up lock dog and top board elasticity movable connection method and adopt top board to be provided with spring hinge, the mode that last lock dog is fixedlyed connected with spring hinge.
For the ease of the interlock of last lock dog with following lock dog, further: the face that caters to of going up lock dog and following lock dog is the inclined plane, and the inclined angle alpha on inclined plane is 30 °.
Pcb board anchor clamps buckle structure of the present invention is simple, can realize easily the open and close of pcb board anchor clamps have been improved operating efficiency, and is reliable and stable at pcb board anchor clamps lock-out state simultaneously, guarantees the welding quality of pcb board.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Among the figure: 1. go up 2. times lock dogs of lock dog, 3. top boards, 4. lower platens, 5. cylinders, 6. spring hinges
The specific embodiment
A kind of pcb board anchor clamps snap close as shown in Figure 1, have last lock dog 1 and following lock dog 2, top board 3 on the pcb board anchor clamps is provided with spring hinge 6, last lock dog 1 is fixedlyed connected with spring hinge 6, lock dog 1 flexibly connects with top board 3 elasticity in the realization, and following lock dog 2 is fixedlyed connected with the lower platen 4 on the pcb board anchor clamps; On lower platen 4, be set with cylinder 5, at last lock dog 1 during with following lock dog 2 snap-lock, when the push rod of cylinder 5 stretches out and last lock dog 1 offset.Last lock dog 1 is the inclined plane with the face that caters to of following lock dog 2, and the inclined angle alpha on described inclined plane is 30 °.
During use, after setting pcb board on the lower platen 4 of PCB anchor clamps, close down top board 1, when top board 1 closes down certain position, last lock dog 1 contacts with the face that caters to of following lock dog 2, because to cater to face be the inclined plane, and the landing of taking advantage of a situation of last lock dog 1, under the effect of spring hinge 6, last lock dog 1 and following lock dog 2 final interlocks.When the pcb board welding finishes, when needing to open top board 3 taking-up pcb boards, only need to start cylinder 5, the push rod of cylinder 5 stretches out, and overcomes 6 pairs of spring hinges and goes up the elastic force that lock dogs 1 apply, and lock dog 1 makes it to break away from and the interlock of following lock dog 2 in promotions, just can upwards start top board 3 this moment, takes out pcb board.
