Abstract
The utility model provides a main shaft brake, which comprises a stop pin, an arresting pin, a stop pin sleeve, a spring, a locating sleeve and a stop pin boss; the stop pin is composed of a pin head, a main body and a handle, a cavity body is arranged in the stop pin sleeve, the stop pin can move fore and after in the pin sleeve, one end of the pressed spring in the cavity body of the stop pin sleeve is mutually connected or adhibited with the jamb wall of the stop pin sleeve, the other end of the spring is connected or adhibited with a limiting circular bead arranged on the main body of the stop pin, the stop pin sleeve is connected with the locating sleeve correspondingly, and both the stop pin sleeve and the locating sleeve are fixed on the stop pin boss. The utility model has the advantages that the cost is low, the damping effect is good, and the operation is convenient. The operating density to optical manufacturing equipment is simplified, and the working efficiency is enhanced.
Description
Affiliated technical field
The utility model relates to a kind of brake apparatus of optics manufacture field, a kind of specifically spindle brake.
Background technology
At existing optics manufacture field, polisher lapper is a kind of optics process equipment relatively more commonly used, but in its use, polisher lapper is not that direct output shaft with reductor links to each other with the mill main shaft sometimes, but pass motion to the main shaft of mill by transmission systems such as belt wheels, what mill and main shaft adopted when changing mill if desired is to be threaded, and just need brake the mill main shaft this moment, just mill can be screwed off then.Traditional mode of braking is comparatively simple, but operation inconvenience promptly becomes four directions or six sides with end mill under the main shaft earlier, in the time will changing mill, just needs two people to cooperate, and a personal spanner or clamp class instrument block main shaft, and another person is responsible for screwing off mill.This traditional braking method not only operates inconvenience but also operating efficiency is low, and if adopt special electric locking infrastructure cost higher relatively, so need a kind of simple spindle braking system.
Summary of the invention
1, goal of the invention: in order to solve existing principal shaft braking method, device operation inconvenience, the more high deficiency of cost, the utility model provides a kind of spindle brake, and this spindle brake is not only simple in structure, operation easily, and also cost is lower, and operating efficiency is higher.
2, technical scheme: a kind of spindle brake described in the utility model is characterized in that: it comprises banking pin, spacer pin, brake pin bushing, spring, positioning sleeve and braking key seat; Banking pin is made up of for three sections pin head, body and handle, brake pin bushing is enclosed within on the banking pin body that is fixed with spacer pin, be provided with cavity in the brake pin bushing, compressed spring is arranged between the sidewall and the spacing shoulder on the banking pin body of brake pin bushing in cavity, promptly rely on the sidewall of elastic spring one end and brake pin bushing to connect or to be coherent, the other end connects or is coherent with the spacing shoulder that is arranged on the banking pin body, the corresponding connection of brake pin bushing with positioning sleeve, and be fixed on jointly on the braking key seat.
Under non-on-position, in order to prevent banking pin on the brake owing to the effect of spring force is moved, spacer pin is stuck in the groove of brake pin bushing.
Operation principle of the present utility model is: because main shaft belt wheel with holes is direct rigid the connection with axle, thereby other driving pulley drives the axle rotation by the belt wheel that belt drives on the main shaft during rotation, when needing braking, insert pairing pin-and-hole on the main shaft belt wheel by banking pin, make the stop motion of main shaft belt wheel, transfer principle by power also stops operating main shaft then, i.e. restriction and hole or the groove class device motion of relatively-stationary directly firmization of axle on axle conveniently screw off mill.
3, beneficial effect: the utility model low production cost, good braking effect, easy to operate.Simplified manipulation strength, improved operating efficiency the optics process equipment.
Description of drawings
Fig. 1 is the non-on-position structural representation of the utility model.
Fig. 2 is the utility model on-position structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, comprise the belt wheel 7 and the main shaft 8 of banking pin 1, spacer pin 2, brake pin bushing 3, spring 4, positioning sleeve 5, braking key seat 6, band brake pin-and-hole.Banking pin 1 is made up of for three sections pin head, body and handle, brake pin bushing 3 is enclosed within on the body of the banking pin 1 that is fixed with spacer pin 2, be provided with cavity in the brake pin bushing 3, compressed spring 4 is arranged between the sidewall and the spacing shoulder on the banking pin body of brake pin bushing 3 in cavity, promptly rely on the sidewall of elastic spring 4 one ends and brake pin bushing 3 to connect or to be coherent, the other end connects or is coherent with the spacing shoulder that is arranged on banking pin 1 body, brake pin bushing 3 and positioning sleeve 5 corresponding linkings, and by screw be fixed on jointly the braking key seat 6 on.Circumferentially process corresponding dowel hole according to the accuracy of location and the size of belt wheel 7 diameters at belt wheel, when making braking key seat 6 during with principal shaft braking earlier, fix by needs with the polisher lapper frame, stopping motor then rotates, main shaft is transferred to desired location, the dowel hole that soon makes progress in belt wheel week is corresponding with the banking pin pin head on the spindle brake, outwards extract the banking pin 1 of brake then, be about to be stuck in that spacer pin 2 shifts out in the groove of brake pin bushing 3, the elastic force that relies on spring according to actual conditions with banking pin 1 revolve turn 90 degrees insert with belt wheel 7 corresponding dowel holes in, promptly realize principal shaft braking, can carry out other associative operations thereupon, as unload lower millstone, change new mill.When main shaft needs operate as normal, when promptly braking need to be removed, can outwards extract banking pin, half-twist then allows spacer pin 2 on the banking pin 1 be stuck in the groove of brake pin bushing 3 to prevent that banking pin 1 from moving under the effect of spring 4 elastic force.Open motor, make the main shaft can normal rotation, thereby carry out operations such as part processing.
It should be noted that spring 4 all is in compressive state when brake is realized braking or the work of non-on-position.
