Parallel connection transmission clutch mechanism
Technical field
The utility model relates to a kind of parallelly connected transmission clutch mechanism.
Background technique
On the whole piece production line of assembling machine, sting the paper wheel assembly by several and form.Sting paper wheel and be installed in and sting on the paper wheel shaft, sting on the paper wheel shaft and through key axle sleeve is installed, through sprocket wheel is installed, sprocket wheel is fixedly connected through drive pin with axle sleeve on the axle sleeve.Sprocket wheel drives drive pin, rotates thereby drive axle sleeve, and axle sleeve drives the paper wheel shaft work of stinging through key.But in practical application, on the assembling machine production line, not that each is stung paper wheel and all needs work.Therefore need a kind of clutch mechanism, when stinging the paper wheel and do not need work, make the disengaging of sprocket wheel and axle sleeve.
The model utility content
The technical problem that the utility model will solve provides a kind of simple in structure, parallelly connected transmission clutch mechanism of cutting down the consumption of energy, reducing equipment attrition.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of parallelly connected transmission clutch mechanism comprises axle sleeve, sprocket wheel, drive pin, wherein also comprises swivel nut, La Gai; Swivel nut is fixed on the sprocket wheel, has radial hole with swivel nut relative position place on the axle sleeve, and the roof anchorage of drive pin is drawn lid; The bottom of drive pin is stretched in the radial hole on swivel nut and the axle sleeve, and the top of swivel nut has first groove along left and right direction, and has second groove along fore-and-aft direction; The height of second groove and the height sum of the radial hole on the axle sleeve are less than or equal to the height of first groove; Draw the bottom of lid to have projection, when projection was positioned at first groove, the lower end of drive pin was stretched in the radial hole on the axle sleeve; When projection was positioned at second groove, the lower end of drive pin proposed the radial hole on the axle sleeve.
The utility model parallel connection transmission clutch mechanism is provided with spring between wherein said drive pin and the swivel nut top.
The utility model parallel connection transmission clutch mechanism is simple in structure, when stinging the paper wheel and do not need work, will draw lid upwards to carry; The projection of La Gai bottom proposes first groove; To draw lid to revolve and turn 90 degrees, projection is placed in second groove, this moment, drive pin broke away from the radial hole of axle sleeve; Sprocket wheel dallies on axle sleeve, and it is motionless with suction paper assembly to sting the paper wheel assembly.Through such improvement, fallen at the end energy consumption and reduced wear and tear in machines again.
Be described further below in conjunction with the parallelly connected transmission clutch mechanism of accompanying drawing the utility model.

Embodiment
Shown in Fig. 1-5; The utility model parallel connection transmission clutch mechanism comprises axle sleeve 2, sprocket wheel 6, swivel nut 4, drive pin 3, draws and cover 5; Axle sleeve 2 is installed in through key 7 and stings on the paper wheel shaft 1, stings paper wheel shaft 1 and passes through Bearing Installation on frame 8, is used for driving and stings 9 rotations of paper wheel.Sprocket wheel 6 is installed on the axle sleeve 2; Fixing swivel nut 4 on the sprocket wheel 6; Have radial hole 21 with swivel nut 4 relative position places on the axle sleeve 2, the top of drive pin 3 is drawn through screw and is covered 5, and the bottom of drive pin 3 is stretched in the radial hole 21 on swivel nut 4 and the axle sleeve 2; Be provided with spring 10 between drive pin 3 and swivel nut 4 tops; The top of swivel nut 4 has first groove 41 along left and right direction, and has along the height sum of the height of second groove, 42, the second grooves 42 of fore-and-aft direction and the radial hole 21 on the axle sleeve 2 height less than first groove 41.Draw and cover 5 bottom and have projection 51, when projection 51 was positioned at first groove 41, the lower end of drive pin 3 was stretched in the radial hole 21 on the axle sleeve 2, and when projection 51 was positioned at second groove 42, the lower end of drive pin 3 broke away from the radial hole 21 on the axle sleeve 2.
When stinging paper wheel 9 and not needing work; To draw and cover 5 and upwards carry, and draw the projection 51 that covers 5 bottoms to propose first groove 41, will draw and cover 5 and revolve and turn 90 degrees; Projection 51 is placed in second groove 42; Drive pin 3 breaks away from the radial hole 21 of axle sleeves 2 at this moment, and sprocket wheel 6 dallies on axle sleeve 2, and it is motionless with suction paper assembly to sting the paper wheel assembly.Through such improvement, fallen at the end energy consumption and reduced wear and tear in machines again.When needs are stung 9 work of paper wheel, projection 51 is proposed second groove 42, will draw and cover 5 and revolve and turn 90 degrees, projection 51 is placed in first groove 41, in the radial hole 21 under the effect of spring 40 on the drive pin 3 insertion axle sleeves 2.Sprocket wheel 6 drive drive pins 3 rotate thereby drive axle sleeve 2, and axle sleeve 2 drives and sting paper wheel shaft 1, stings 9 rotations of paper wheel through key 7.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technological scheme of the utility model all should fall in the definite protection domain of the utility model claims.
