Abstract
The invention discloses a ratchet wheel brake mechanism for a punch press. The ratchet wheel brake mechanism comprises a crankshaft, a ratchet wheel and a ratchet wheel manipulator; a ratchet wheel inner sleeve movably matched with the ratchet wheel is mounted on the crankshaft; the ratchet wheel manipulator is composed of a pawl shaft, a spring, a pawl and an electromagnet; a positioning convex rod is arranged on the ratchet wheel; the positioning convex rod is connected with a poking claw integrally; the poking claw is connected with a proximity switch and an operating lever; the operating lever is connected with an on-off device. The ratchet wheel brake mechanism for the punch press is used for realizing emergency braking of a slider in any position in case of emergency in the punching process of the punch press; as a result, the safety and reliability of practice are guaranteed, and the injury accidents in the production practice can be effectively avoided.
Description
Technical field
The invention belongs to the technical field of fixture, particularly relate to a kind of ratchet gear brake mechanism for punch press.
Background technology
Brake apparatus is for realizing the action stopping or lowering speed.Often use lathe during colleges and universities' model specialty practising method, traditional machine operation gets up danger coefficient comparatively greatly, can only protect the safety of the both hands of operator before punching press starts, and can not carry out brake hard for slide block movement during punching press.This is breakneck for the student just contacting operating punch machine, therefore needs one for the brake apparatus of punch press, guarantees the safe and reliable of practice, effectively avoid the generation of disability accident in production practice.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of ratchet gear brake mechanism for punch press is provided, the safe and reliable of practice can be guaranteed, effectively avoid the generation of disability accident in production practice.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of ratchet gear brake mechanism for punch press, comprise bent axle, ratchet and ratchet executor, described bent axle is installed on the ratchet inner sleeve coordinated with ratchet activity, described ratchet executor is made up of pawl axis, spring, ratchet and electromagnet, described ratchet is provided with positioning convex rod, described positioning convex rod is connected with pusher dog and is connected integral with it, and described pusher dog is connected with proximity switch and control stick, and described control stick is connected with arrangement of clutch.
Further, the below of described pusher dog is connected with spring.
Arrestment mechanism of the present invention is that energising departs from, the friction brakes of spring to break braking.The performance of power-off brake type electromagnetic brake is: state that brake shoe and brake wheel are at ordinary times " embracing ", when motor obtains electric starting, the coil in parallel with it also simultaneously electric, attract armature, make it and iron core adhesive, and lever moves by the elastic force overcoming spring, forces releasing of brake, Braking Action None; When power source, coil also simultaneously dead electricity, armature is released, and is that brake shoe tightly embraces brake wheel under spring force, realizes braking rapidly.
The invention has the beneficial effects as follows:
The present invention realizes slide block brake hard at an arbitrary position when punch press is in an emergency in punching course, ensure that the safe and reliable of practice, effectively prevent the generation of disability accident in production practice.
Accompanying drawing explanation
Accompanying drawing described herein is used to provide a further understanding of the present invention, and form a application's part, schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of embodiment of the present invention;
Number in the figure illustrates: 1-bent axle, 2-ratchet inner sleeve, 3-ratchet, 31-nose bar, 4-ratchet executor, 41-pawl axis, 42-spring, 43-ratchet, 44-electromagnet, 5-pusher dog, 6-proximity switch, 7-control stick, 8-arrangement of clutch.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
As shown in Figure 1, a kind of ratchet gear brake mechanism for punch press, comprise bent axle 1, ratchet 3 and ratchet executor 4, described bent axle 1 is installed on the ratchet inner sleeve 2 coordinated with ratchet 3 activity, described ratchet executor 4 is made up of pawl axis 41, spring 42, ratchet 43 and electromagnet 44, and described ratchet 3 is provided with positioning convex rod 31, and described positioning convex rod 31 is connected with pusher dog 5 and is connected integral with it, described pusher dog 5 is connected with proximity switch 6 and control stick 7, and described control stick 7 is connected with arrangement of clutch 8.
Further, the below of described pusher dog 5 is connected with spring.
The operation principle of the present embodiment is as follows:
During work, electromagnet 44 obtains electric, and ratchet 43 is opened, and ratchet 3 rotates, and the pusher dog 5 of arrangement of clutch 8 drives nose bar 31 to move, and nose bar 31 drives ratchet 3 to rotate together simultaneously; When needs brake hard; press scram button; electromagnet 44 dead electricity; ratchet 43 is left behind by spring 42; ratchet 3 is made by ratchet 43 and stops operating; the pusher dog 5 that the simultaneously unexpected stopping of ratchet 3 makes nose bar 31 contact also can stop motion thereupon, and arrangement of clutch 8 is disconnected immediately, realizes safeguard protection.
When the electromagnet in arrangement of clutch 8 obtains electric, control stick 7 rotates, and pusher dog 5 is rotated counterclockwise under the action of the spring, and clutch apparatus 8 is connected; Because pusher dog 5 leaves action bars 7, proximity switch 6 is connected and is made the electromagnet 44 of ratchet 43 and the electromagnet of clutch apparatus 8 keep electric; Blocked by control stick 7 after pusher dog 5 rotates a circle, arrangement of clutch 8 disconnects, and proximity switch 6 disconnects, the electromagnet 44 of ratchet 43 and the electromagnet dead electricity of clutch apparatus 8; Protector sense staff at dangerous position or press scram button because of danger time, punch press can realize brake hard.
