Description

A kind of turning cylinder axle head hold-down mechanism

Technical field

The utility model relates to turning cylinder axle head hold-down mechanism technical field.

Background technology

In the assembling of common mechanical parts, the compression of axle head cover component, the frame mode adopting shaft end ring and bolt thereof to screw compression more.This axle head compressing structure is most widely used in the component of machine of reduced size, but it is large to be used in size, particularly be used in the component of machine of outside axial force and impact shock load working condition, under the double action of the complicated alternate stress that its hold-down bolt is formed in large scale large rotating inertia, impact shock and axial force and pretightning force, just be easy to just fracture, there is the substantial equipment potential safety hazard that great end parts come off or fly out.

Summary of the invention

The purpose of this utility model is to solve prior art Problems existing, provides a kind of safe and reliable macro-axis axle head hold-down mechanism.

The purpose of this utility model is achieved by the following technical solution.

A kind of turning cylinder axle head hold-down mechanism, the outer end that the turning cylinder of part is housed in end sleeve is circumferentially processed with the draw-in groove of band axle head bayonet socket, the bottom surface counterbore concordant with draw-in groove internal face is processed with in the endoporus outer face of part, the clamp of band endoporus latch is set with in draw-in groove, the gland-type pressing plate of cover rim band tenon tooth is stamped, by the axial end tight joint of hold-down bolt by pressing plate and turning cylinder at clamp external pressure; The endoporus latch of bayonet type clamp is compressed into draw-in groove by axle head bayonet socket and is rotated an axle head bayonet socket position, blocked by axle head latch, the face that contacts with each other of clamp endoporus latch and axle head latch is inclined-plane, pressing plate bottom surface is pressed on counterbore bottom surface and draw-in groove internal face, and the tenon tooth of pressing plate inserts in the bayonet socket between clamp endoporus latch.

The utility model is processed with handling and knocks and help hole in clamp outer face.

The axle head hold-down mechanism of the utility model structure, clamp loads the draw-in groove of axle head, and rotate a bayonet socket position, the inclined-plane slippage utilizing axle head latch and clamp latch to contact, realizes the object of axial compression axle head part, compresses without the need to bolt and shaft end ring.Gland-type pressing plate with tenon tooth and hold-down bolt thereof serve the effect preventing clamp convolution from deviating from.Namely achieving the complicated alternate stress that large scale large rotating inertia, impact shock and axial force comprehensively formed thus transfers to clamp to carry but not hold-down bolt carrying, can stop or reduce the substantial equipment potential safety hazard that the end parts that cause due to hold-down bolt fracture come off or fly out.The utility model structure is relatively simple, mounting or dismounting are convenient, be easy to processing, low cost of manufacture.

Content of the present utility model is set forth further below in conjunction with Figure of description.

Detailed description of the invention

As shown in Fig. 1 ~ Fig. 8, the utility model is equipped with part 3 (as gear, belt wheel etc.) in the end sleeve of turning cylinder 1, and turning cylinder is connected by linking bond 2 with part.The draw-in groove 1b of band axle head bayonet socket 1a is circumferentially processed with in the outer end of turning cylinder 1, the bottom surface counterbore 3a concordant with draw-in groove internal face is processed with in the endoporus outer face of part, the clamp 4 of band endoporus latch 4a is set with in draw-in groove, the gland-type pressing plate 5 of cover rim band tenon tooth 5a is stamped, by the axial end tight joint of hold-down bolt 6 by pressing plate and turning cylinder at clamp external pressure.The endoporus latch of described bayonet type clamp 4 is compressed into draw-in groove by axle head bayonet socket 1a and rotates an axle head bayonet socket position, blocked by axle head latch 1c, the face that contacts with each other 4b, 1d of clamp endoporus latch 4a and axle head latch 1c are inclined-plane, its gradient is generally 1:12, pressing plate bottom surface is pressed on counterbore bottom surface and draw-in groove internal face, and the tenon tooth 5a of pressing plate inserts in the bayonet socket between clamp endoporus latch 4a.Be processed with handling to knock help hole 4c in clamp 4 outer face, during for clamp being clamped precession draw-in groove or rotate backward aid insertion point when unloading.

As shown in Figure 2 and Figure 3, draw-in groove is gone out at axle head car, and the outer end mill of draw-in groove is become uniform circumference male and female latch and bayonet socket, the inner face of each latch mills out the circumference gradient of 1:12 in the same way, this gradient assemble time and clamp endoporus latch outer face gradient fit, when clamp rotates a latch position, namely produce the axial displacement compressing axle head part.

As shown in Figure 5, Figure 6, the accessory processing of clamp endoporus is become uniform circumference male and female endoporus bayonet socket and endoporus latch, each endoporus latch mills out the circumference gradient of 1:12 in the same way, this gradient assemble time and axle head latch gradient fit, when clamp rotates a latch position, namely produce the axial displacement compressing axle head part.

As shown in Figure 7, Figure 8, gland-type platen cover is become uniform circumference male and female tenon tooth and tooth mouth along accessory processing, to insert groove when assembling, circle round to stop clamp.

During installation, turning cylinder 1 is installed and is anchored on equipment support or body, linking bond 2 and suit end part 3 is loaded in the keyway of turning cylinder end, by bayonet socket, the latch male orientation to mother, clamp 4 is overlapped in the draw-in groove of loading axle head, rotate a latch position, as a same reason the tenon tooth of pressing plate 5 is inserted in axle head bayonet socket subsequently and also compressed with bolt 6.
