Specific embodiment
With reference to the accompanying drawing and specific embodiment is further elaborated the technical solution of the utility model.
A kind of taper hole measurer, including mounting rack 1, the dial gauge 2 being detachably arranged on the mounting rack 1 and thimble 3, ginseng As shown in FIGS. 1 and 2.The mounting rack 1 includes horizontal bottom beam 11, is symmetrically arranged with left vertical bar on the both ends of the horizontal bottom beam 11 12 with right vertical bar 13, shown in Figure 1, the dial gauge 2 and thimble 3 are separately mounted to left vertical bar 12 on right vertical bar 13, this hundred Divide the axial line of table 2 and the coaxial arrangement of thimble 3 and the two horizontally extending.The test lead of the dial gauge 2 and the top of thimble 3 3, needle are pressed in taper hole 4 to be measured, in opposite direction on the hole inner wall of position to be measured, which goes back on right vertical bar 13 It is connected separately with left cross bar 14 and right cross bar 15, shown in Figure 1, the left cross bar 14 is with right cross bar 15 along the perpendicular of horizontal bottom beam 11 Straight center line symmetrical setting, the left cross bar 14 extend outwardly in opposite direction with right cross bar 15, for by mounting rack 1 be supported on to It surveys on the aperture end face of taper hole 4.In this example, by setting mounting rack 1 and coaxially and in opposite direction it is pressed on taper hole to be measured 4, the dial gauge 2 on the hole inner wall at position to be measured and thimble 3 to realize the measurement to taper hole aperture, and pass through two energy The measurer of different location is enough measured, it can be achieved that measurement to taper hole taper.In this example, the horizontal bottom beam 11, left vertical bar 12, the right side are perpendicular Bar 13, left cross bar 14, right cross bar 15 are integrally formed.By the way that integrally formed mounting rack 1 is arranged, the rigidity of mounting rack 1 is increased.
The first mounting hole 16 for installing dial gauge 2 is offered on the left vertical bar 12, shown in Figure 2, first peace The axial line for filling hole 16 is horizontally disposed, is additionally provided on the mounting rack 1 for dial gauge 2 to be locked on left vertical bar 12 First locking member 5, it is shown in Figure 1.Here, which is the bolt clip 5 on horizontal bottom beam 11, the bolt Folder 5 includes chuck body, and the clamping part for clamping the dial gauge 2 is offered in the chuck body, which is in half-open knot Structure, the clamping part and 16 coaxial inner conductor of the first mounting hole are arranged.Here, which further includes clamping screw 51, referring to Fig. 1, Shown in 2, the bolt hole for installing the clamping screw 51 is offered in the chuck body, when the test lead of dial gauge 2 is along itself Axially across be pressed on after the clamping part on the bolt clip 5, the first mounting hole 16 on the left vertical bar 12 taper hole 4 to be measured, to When on the hole inner wall that location is set, the clamping part is locked by clamping screw 51, so that dial gauge 2 is locked at left vertical bar 12 On.
The second mounting hole 17 for installing thimble 3 is offered on the right vertical bar 13, shown in Figure 2, second installation The axial line in hole 17 is horizontally disposed, which further includes the second locking for locking thimble 3 with right 13 phase of vertical bar Part 6, ginseng as shown in FIGS. 1 and 2.Here, which is locking nut 6, when the thimble head of thimble 3 is along self-axis line side To when wearing on the hole inner wall by being pressed on taper hole 4 to be measured after the second mounting hole 17, which is locked by locking nut 6 On the right vertical bar 13.
In this example, the axial line of the dial gauge 2 away from the distance of the aperture end face of taper hole 4 to be measured with it is to be measured in taper hole 4 to be measured The depth of position is consistent.Specifically, dial gauge 2 and thimble is arranged according to the position to be measured in the taper hole to be measured 4 specifically detected 3 installation site, and the measurer used is that detection is completed inside taper hole, the precision of detection is improved, entire to measure The structure of tool is simple, easy to operate, and accuracy is high.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention. All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it It is interior.
