Abstract
The invention discloses a clamping piece for detecting the radial run-out of the side face of a pulley groove of a shock absorber. The clamping piece comprises a mandrel and a locking swivel nut. The mandrel comprises a mandrel body. Three elastic jaws are circumferentially arranged in the middle position of the mandrel body at intervals. The outer walls of the elastic jaws are conic. The middle positions of the inner sides of the elastic jaws are connected with the side wall of the mandrel body through a supporting body. Gaps are formed between the inner sides of the elastic jaws located on the two sides of the supporting body and the side wall of the mandrel body. The elastic jaws can swing around the supporting body, so that the radial distances between the outer walls of the three elastic jaws and the center of the mandrel body are changed. The locking swivel nut is in threaded connection with the front end of the mandrel body. When the mandrel body is sleeved with a pulley of the shock absorber, the pulley of the shock absorber can be driven by the locking swivel nut to be tensioned on the outer walls of the three elastic jaws. The clamping piece can be used for clamping the shock absorber with an inner hole large in taper and with a stepped hole, detection is convenient, and accuracy is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
As shown in Figures 1 and 2, according to a kind of holder detecting the side circular runout of shock absorber pulley groove of the specific embodiment of the invention, comprise mandrel 1 and locking swivel nut 2.Wherein mandrel 1 comprises mandrel body 12, at circumference interval, the centre position of mandrel body 12, three elastic claws 11 are set, the outer wall of elastic claw 11 is taper, in the present embodiment, the centre position of the inner side of elastic claw 11 is connected (see Fig. 3) by supporter 111 with the sidewall of mandrel body 12, the sidewall of the inner side and mandrel body 12 that are in the elastic claw 11 of supporter 111 both sides has gap, and elastic claw 11 can swing around supporter 111 and then the outer wall of three elastic claws 11 be changed to the radial distance at the center of mandrel body 12.In addition, locking swivel nut 2 is threaded with the leading section of mandrel body 12, and when shock absorber belt pulley 3 (see Fig. 9) is enclosed within mandrel body 12, locking swivel nut 2 can drive shock absorber belt pulley 3 tensioner on the outer wall of three elastic claws 11.
In technique scheme, by arranging three elastic claws 11 with self-centering and Auto-matching taper hole surface along its circumferential interval on the sidewall of mandrel body 12, as a kind of specific embodiment, it is 1:10 that the male cone (strobilus masculinus) theory of three elastic claws 11 manufactures tapering.Then, configure a locking swivel nut 2 and axial pressing force is provided, and then the end face promoting tested shock absorber belt pulley 3 makes elastic claw 11 produce the taper hole being out of shape and adapting to the distribution of various error, the tested shock absorber belt pulley 3 of radial tensioner, solves endoporus and is steep-taper and a tensioner difficult problem with shoulder hole and the unserviceable shock absorber belt pulley 3 of end face simultaneously.In this programme, by designing three elastic claws 11 of automatic swing, can guarantee that this mandrel 1 energy accurate simulation goes out the benchmark taper hole axis of shock absorber belt pulley 3.Meanwhile, three elastic claws 11 are connected with mandrel body 12 one, and only rely on the fulcrum (supporter 111) at middle part to produce during work and swing, have the function of self adaptation taper hole taper error, systematic error is little, and precision is high.
As a kind of preferred embodiment, the centre position of the outer wall of elastic claw 11 concaves, also namely the tensioner face of the outer wall of elastic claw 11 comprises two parts, be respectively leading section and rearward end, make elastic claw 11 easily produce the taper hole being out of shape and adapting to the distribution of various error, facilitate the tested shock absorber belt pulley 3 of radial tensioner.
As a kind of preferred embodiment, three elastic claws 11 are machining on the sidewall of mandrel body 12.See Fig. 4 to Fig. 7, the diameter of the mid portion of mandrel body 12 is greater than two ends (in the present embodiment, the tail end of mandrel body 12 also has circular base plate 13), the fore-end of mandrel body 12 installs locking swivel nut 2, and the two ends of mandrel body 12 are provided with installing hole, mandrel body 12 can be arranged on deflection instrument by the installing hole at two ends.Specifically adding man-hour, the mid portion of mandrel body 12 offers three road grooves along its circumferential interval, the outer wall of the entity between adjacent slot is processed into taper, and the middle indent of outer wall, then the entity between adjacent slot is cut from inward at both ends, be cut to middle reserved part and form supporter 111.Finally carry out deburring, the process of turning blue of chamfering, surface forms three elastic claws 11.
As a kind of preferred embodiment, the front end of locking swivel nut 2 has flange shape boss, and this flange shape boss is used for being connected to the end face of shock absorber belt pulley 3.
Finally; as shown in Figure 9; at the two ends output protection type centre bore of mandrel 1, general deflection instrument (top 51 of deflection instrument shown in Fig. 9) and dial gauge 4 can be coordinated just to the detection of shock absorber pulley groove side circular runout project, and measurement is safer, convenient.
Below for the shock absorber product of certain model, illustrate the using method of this holder and the detection method of shock absorber pulley groove side circular runout, concrete steps are as follows:
1) be placed in the mandrel of elastic claw and locking swivel nut and tested shock absorber on platform, and with clean cotton by each working surface and each bore area wiped clean.
2) first with hand, the locking swivel nut on mandrel is back-outed outward, then mandrel is inserted shock absorber endoporus, and with locking swivel nut by shock absorber tensioner.
3) by be placed in together with tested shock absorber and mandrel and locking swivel nut general deflection instrument top on, the probe of dial gauge is abutted shock absorber pulley groove side, tested shock absorber rotates a circle, the reading change of dial gauge and the circular runout of shock absorber pulley groove side.
4) measure end, unscrew locking swivel nut with instrument, and mandrel is taken out from shock absorber endoporus.
5) with clean cotton by each for mandrel working surface wiped clean, oil and deposit and preserve.
To sum up, the holder of the detection shock absorber pulley groove side circular runout of the present embodiment, according to the testing requirement of shock absorber pulley groove side circular runout project to be measured, benchmark taper hole axis is simulated by designing a flexible mandrel of grabbing of band, and provide the taper hole that can adapt to the distribution of various error during axial force at locking swivel nut, ensure energy tensioner shock absorber belt pulley in the benchmark taper hole tapering margin of tolerance, this holder coordinates general deflection instrument, can be steep-taper to endoporus and there is shoulder hole and end face unserviceable shock absorber pulley groove side circular runout project implementation detection, detection efficiency is high, expense is low, easy to operate.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
