Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments the utility model 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 that restriction two push rods 5 laterally move is set respectively between central block 1 and two push rods 5, stop means is set to be socketed in respectively the adjustment cover 7 on two push rods 5, adjust cover 7 and be threaded with the telescopic cavity 11 of central block 1, be provided with at central block 1 and drive the driving mechanism 8 that two push rods 5 stretch.Driving mechanism 8 is formed by being symmetrically set in telescopic cavity 11, the coil tension spring 9 that arranges in the central block 1 and can driving two push rods outwardly directed control lever 10 of 5 while when moving down telescopic cavity 11 in, 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 two abutting ends 51 respectively and is overlapped between 7 with adjusting.For ease of operation, control lever 10 and central block 1 are by being threaded.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 tensioner bolt 1 to measure.After finishing, measurement screws out tensioner bolt 1, both sides push rod 5 withdrawals 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, adjust cover 7 and are 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 to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
