Description of drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and the specific embodiments the present invention is described in further details;
As shown in Figure 1, a kind of axle housing self-centering appliance special for detecting, comprise and have two telescopic cavities, 11 central blocks 1, be provided with the positioning pressuring plate 4 that is connected with the end face for the treatment of gaging hole 23 on the axle housing in the both sides of central block 1, be provided with in the both sides of central block 1 can be along the center of central block 1 to the flexible push rod 5 of two inwalls 21 for the treatment of gaging hole 2, be provided with a guiding external member 6 that allows two push rods 5 to pass at positioning pressuring plate 4.
The stop means of restriction two push rods 5 transverse shiftings is set respectively between central block 1 and two push rods 5, stop means is set to be socketed in respectively the adjusting sleeve 7 on two push rods 5, adjusting sleeve 7 is threaded with the telescopic cavity 11 of central block 1, is provided with at central block 1 and drives the driving mechanism 8 that two push rods 5 stretch.Driving mechanism 8 by be symmetrically set in telescopic cavity 11 in the central block 1, can drive at the coil tension spring 9 of telescopic cavity 11 interior settings and when moving down two push rods 5 simultaneously outwardly directed control lever 10 form, coil tension spring 9 is set on two push rods 5, the abutting end 51 of two push rods 5 passes through coil tension spring 9 Elastic Contact in central block 1, control lever 10 comprises operating side 12 and drive end 13, drive end 13 respectively with central block 1 in two abutting ends, 51 Elastic Contact, coil tension spring 9 is located at respectively between two abutting ends 51 and the adjusting sleeve 7.For ease of operation, control lever 10 is threaded connection with central block 1.Be provided with the detection piece 14 that detects the center, hole behind push rod 5 location at central block 1, detection piece 14 is for laterally being located at the stock with two test sides at 12 tops, operating side on the control lever 10.
For guaranteeing that the distance that two push rods 5 stretch out equates, two abutting ends 51 of push rod 5 all are set to spherical structure, the drive end 13 of control lever 10 is set to the cone-shaped body that contacts with the spherical surface of two spherical structures respectively, and the top of this cone-shaped body is located on the axis of two push rods 5.
Cubing both sides positioning pressuring plate 4 is leaned against the end face 3 in hole, and the drive end 13 of control lever 10 puts in the central block 1, and rotating operation bar 10 drive end 13 is screwed in the central blocks 1, and it is protruding to promote two push rods 5, pushes against two inwalls 21 for the treatment of gaging hole 2.Suitably rotate cubing this moment, can utilize the periphery of tension bolt 1 to measure.Back-out tension bolt 1 after measurement is finished, both sides push rod 5 is retracted under the effect of coil tension spring 9.Wherein, both sides guiding external member 6 and central block 1 guarantee the right alignment of two ends push rod 5, and adjusting sleeve 7 is the pre compressed magnitude of control coil tension spring 9.
Because higher, the structural symmetry of machining precision of each part of cubing, the protruding distance of both sides push rod equate that all the time even the center pit aperture changes, but the center of cubing is constant all the time.Therefore, this cubing can be common to the detection of a series of center pits that the aperture is more or less the same.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
