Abstract
The utility model discloses an anti-rotation locking mechanism, which comprises a locking pin, wherein one end of the locking pin is a threaded section, and a locking groove is arranged on the circumference at the other end of the locking pin; a to-be-locked shaft is clamped and embedded in the locking groove, and the circumferential surface of the to-be-locked shaft is propped against the concave surface of the locking groove; and a nut for fastening the locking pin is sleeved on the threaded section of the locking pin. The circumferential surface of the to-be-locked shaft is matched with the locking groove of the locking pin, when the locking pin is fastened, the surface of the shaft is closely joined with that of the locking groove, and therefore the shaft is fastened and prevented from rotating. The anti-rotation locking mechanism is particularly suitable for locking parts such as a shaft and preventing the parts from rotating, and has the advantages that the locking reliability is high, the shaft surface is prevented from being damaged, the stepless regulation of the shaft can be realized, and the structure is simple, and the mechanism is simple and convenient to operate.
Description
Technical field
The utility model relates to a kind of anti-rotation locking mechanism, especially a kind of anti-rotation locking mechanism that is used for the lock shaft type component.
Background technique
In engineering machinery, axle is a kind of rotary component commonly used.Axle sometimes needs it to rotate usually as the part of low speed underloading controlling mechanism, reaches the purpose of adjusting; Sometimes need it not rotate, need axle is fixed on a certain position or a plurality of position.In prior art, a structure that is used for the locking of a spool class anti-rotation has two kinds of flange plate type locking mechanism and lock screw formula locking mechanisms usually.
The flange plate type locking mechanism has the characteristics of reliable lock.As shown in Figure 4, axle 4 is fixedlyed connected with flange plate 5, and several holes or locking groove 51 are arranged on the flange plate 5, by locking key 6 is snapped in locking groove 51, axle 4 is locked the processing technology difference of hole or locking groove 51 and cost height; During adjusting, can only can not realize step-less adjustment by locking key 6 being snapped in the relative position that different locking groove 51 carries out axle 4.Owing to be provided with flange plate 5,, cause equipment volume to increase in addition so the radially volume of axle 4 is bigger.
Lock screw formula locking mechanism as shown in Figure 5 has the radially little characteristics of volume.But the head of lock screw 7 is point relatively, need during locking lock screw 7 heads are pressed on the side face of axle 4, often form pit, axle 4 surfaces that also may scratch during overload, reliable lock is poor, and axis body intensity, surface quality and assembling are all had adverse effect.
The model utility content
The utility model is the deficiency that exists in the above-mentioned prior art for avoiding, and a kind of anti-rotation locking mechanism is provided, with the step-less adjustment that improves reliable lock, avoids damaging the axle surface and realize axle.
The utility model be the technical solution problem by the following technical solutions.
Anti-rotation locking mechanism, its structural feature be, comprises spring bolt, and an end of spring bolt is a thread section, in the periphery of the spring bolt the other end locking groove is set; Be locked an inlay card in the locking groove, and an outer peripheral surface that is locked offsets with the concave surface of locking groove; On the thread section of spring bolt, be arranged with the nut that is used for fastening spring bolt.
The structural feature of anti-rotation locking mechanism of the present utility model also is:
Also be arranged with the packing ring that is used with nut on the described spring bolt.
Described packing ring is a plain washer.
Described packing ring is a spring washer.
Compared with the prior art, the utility model beneficial effect is embodied in:
Anti-rotation locking mechanism of the present utility model is provided with spring bolt, by the locking groove on the spring bolt will be locked the axle tightly fixing, prevent to be locked the axle rotate.The mode that surface surperficial by axle and the locking groove fits tightly is with shaft locking, and the cooperation between axle and the spring bolt is that face cooperates, and the cooperation area is big, and the reliable lock height can not damage the axle surface.By nut that spring bolt is fastening, unclamp the promptly rotatable axle that is locked of nut, simple in structure, simple to operation, can realize the step-less adjustment of axle.Anti-rotation locking mechanism of the present utility model has the reliable lock height, can not damage axle surface, the step-less adjustment that can realize axle, advantage simple in structure and simple to operation.
The utility model is particularly useful for the lock shaft type component, is used for shaft locking is prevented that axle from rotating.

Label in accompanying drawing 1～accompanying drawing 5: 1 nut, 2 spring bolts, 21 thread sections, 22 locking grooves, 3 packing rings, 4,5 flange plate, 51 locking grooves, 6 locking keys, 7 lock screws.
Below pass through embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings.
Embodiment
Referring to Fig. 1～Fig. 3, the anti-rotation locking mechanism comprises spring bolt 2, and an end of spring bolt 2 is a thread section 21, in the periphery of spring bolt 2 the other ends locking groove 22 is set; Be locked axle 4 inlay cards in locking groove 22, and axle 4 outer peripheral surfaces that are locked offset with the concave surface of locking groove 22; On the thread section 21 of spring bolt 2, be arranged with the nut 1 that is used for fastening spring bolt 2.Also be arranged with the packing ring 3 that is used with nut 1 on the described spring bolt 2.Described packing ring 3 is plain washer or spring washer.
The flute profile of locking groove 22 can be held the axle 4 that is locked just, and groove bottom is an arc, for be locked axle 4 with after 2 two cylindrical bodys of spring bolt pass through mutually with the shape after the two superposed part is downcut on the spring bolt 2.In the present embodiment, the axis of the axle 4 that is locked and the axis of spring bolt 2 are vertical mutually.
Anti-rotation locking mechanism of the present utility model is provided with spring bolt, by the locking groove on the spring bolt will be locked the axle tightly fixing, prevent to be locked the axle rotate.The mode that surface surperficial by axle and the locking groove fits tightly is with shaft locking, and the cooperation between axle and the spring bolt is that face cooperates, and the cooperation area is big, and the reliable lock height can not damage the axle surface.By nut that spring bolt is fastening, unclamp the promptly rotatable axle that is locked of nut, simple in structure, simple to operation.Anti-rotation locking mechanism of the present utility model has the reliable lock height, can not damage surperficial, the simple in structure and simple to operation advantage of axle.
The utility model is particularly useful for the lock shaft type component, is used for shaft locking is prevented that axle from rotating.
