Abstract
The pin pulling out device of a kind of dry friction clutch of the utility model is a kind of device of pulling pin for clutch brake pin in dry friction clutch.Comprise pull pin body and stud, described stud has upper stud and lower stud, and upper stud and lower stud are respectively by being threaded into body two ends of pulling pin; Pull pin between body and pin and be threaded connection; The upper stud at body two ends of pulling pin rotates until contacted with bed piece or flywheel wheel body by stud bar with lower stud, continue to rotate two ends stud, stud original place is rotated, the effect that body of pulling pin runs due to spiral is moved outward, thus pin outwards movement, until pin entirety is extracted beyond pin-and-hole, thus realize pulling pin.
Description
Technical field
The pin pulling out device of a kind of dry friction clutch of the utility model is a kind of device of pulling pin for clutch brake pin in dry friction clutch.
Background technique
Dry friction clutch is the core component of forging machine tool, the work of lathe is by the stroke moved up and down of Clutch Control lathe slide block and the required station of work, the working principle of clutch is exactly utilize the main body of friction plate and the clutch that central layer is riveted and cylinder to carry out combining and produce the action that frictional force completes clutch and braking, thus controls the stroke of forging machine tool slide block.Therefore friction plate is the easily damaged parts in clutch, needs often to change, and simultaneously because the main working performance of clutch utilizes pneumatic mode to promote cylinder body in clutch to move, therefore seal ring also easily weares and teares, and needs regularly to carry out maintain and replace.In maintain and replace process, need the clutch brake pin be connected with clutch brake central layer in clutch to extract from lathe and flywheel, the mode of usual employing is extracted by pin by failure mode, this will increase maintenance cost, extract pin due to failure mode easily causes machine tool accuracy to decline seriously simultaneously, affect the braking clutch performance of clutch, thus affect the usability of lathe.
Model utility content
The purpose of this utility model is the pin pulling out device providing a kind of dry friction clutch for above-mentioned deficiency, it is the device of pulling pin from bed piece and flywheel for the clutch brake pin in dry friction clutch, guarantee that dry type clutch break does not damage clutch brake pin in maintenance, ensure that lathe work precision performance is unaffected.
A kind of pin pulling out device of dry friction clutch takes following technological scheme to realize:
The pin pulling out device of dry friction clutch comprises pull pin body and a stud, and described stud has upper stud and lower stud, and upper stud and lower stud are respectively by being threaded into body two ends of pulling pin; Pull pin between body and pin and be threaded connection; The upper stud at body two ends of pulling pin rotates until contacted with bed piece or flywheel wheel body by stud bar with lower stud, at this moment continue to rotate two ends stud, now stud can only rotate in original place, and the effect that body of pulling pin runs due to spiral is moved outward, thus pin outwards movement, until pin entirety is extracted beyond pin-and-hole, thus the effect that realization is pulled pin.
The pin pulling out device of a kind of dry friction clutch of the utility model, reasonable in design, structure is simple, does not destroy any component, ensures the precision of pin-and-hole and reusing of pin, does not affect the usability of lathe; Can ensure institute extract reusing and pin-and-hole precision of pin, reduce keep in repair user cost, guarantee the usability of lathe.
Accompanying drawing explanation
Below with reference to accompanying drawing, the utility model is described in further detail:
Fig. 1 is that the pin pulling out device of the utility model dry friction clutch uses schematic diagram.
In figure: 1, machine tool body or flywheel body, 2, pin, 3-1, upper stud, 3-2, lower stud, 4, body of pulling pin.
Embodiment
With reference to accompanying drawing 1, a kind of pin pulling out device of dry friction clutch comprises pull pin body 4 and stud 3, and described stud has upper stud 3-1 and lower stud 3-2, upper stud 3-1 and lower stud 3-2 and pulls pin in the tapped hole at body 4 two ends respectively by being threaded into; Pull pin between body 4 and pin 2 and be threaded connection; The upper stud 3-1 at body 4 two ends of pulling pin rotates until contacted with bed piece or flywheel wheel body by stud bar with lower stud 3-2, at this moment continue to rotate two ends stud, now stud can only rotate in original place, and the effect that body 4 of pulling pin runs due to spiral is moved outward, thus pin 2 outwards movement, until pin 2 entirety is extracted beyond pin-and-hole, thus the effect that realization is pulled pin.
Claims (1)
1. a pin pulling out device for dry friction clutch, is characterized in that: comprise pull pin body and stud, and described stud has upper stud and lower stud, and upper stud and lower stud are respectively by being threaded into body two ends of pulling pin; Pull pin between body and pin and be threaded connection; The upper stud at body two ends of pulling pin rotates until contacted with bed piece or flywheel wheel body by stud bar with lower stud, continue to rotate two ends stud, stud original place is rotated, the effect that body of pulling pin runs due to spiral is moved outward, thus pin outwards movement, until pin entirety is extracted beyond pin-and-hole, thus realize pulling pin.
