Abstract
The invention relates to the technical field of workpiece detecting devices, in particular to a novel vernier caliper which comprises a main caliper and a sub vernier caliper capable of sliding on the main caliper. The main caliper and the sub vernier caliper are provided with two pairs of movable measuring jaws which are inner measuring jaws and outer measuring jaws. The novel vernier caliper is characterized in that each inner measuring jaw comprises a horizontal rod and a vertical rod connected with the horizontal rod, the horizontal rod and the vertical rod of each inner measuring jaw are connected in an inverse-L shape, spherical measuring blocks are arranged on measuring faces of the inner measuring jaws, and the width of a dovetail groove can be quickly measured.
Description
Technical field
The present invention relates to Workpiece detecting device technical field, particularly relate to Novel vernier caliper.
Background technology
Dovetail groove is used in mechanical relative motion usually, and kinematic accuracy is high, stable. the normal and trapezoidal rails of dovetail groove with the use of, be lead and supporting role. often use on the planker of lathe; But after dovetail groove processes, due to the restriction of structure, common cubing, as vernier caliper, is difficult to stretch into the width measuring dovetail groove.
Summary of the invention
The object of this invention is to provide a kind of Novel vernier caliper that can detect dovetail groove width fast.
Technical scheme of the present invention is as follows:
Novel vernier caliper, comprises main scale, and the secondary chi of the vernier that can slide on main scale; Described main scale and the secondary chi of vernier are provided with two secondary movable measuring jaws, and two secondary movable measuring jaws are respectively internal measure-hand and external pelivimetry pawl; Described internal measure-hand comprises cross bar, and the montant be connected with cross bar, and described internal measure-hand cross bar is connected in inverted "L" shaped with montant; The measuring surface of described internal measure-hand is equipped with spherical survey block.
Described internal measure-hand montant comprises the upper montant with the first screw and the lower montant with the first stud, and is connected with increment bar between upper montant and lower montant; Described increment masthead end is provided with second stud that can insert in the first screw, described increment bar bottom be provided with the first stud with the use of the second screw.Because the montant central authorities at internal measure-hand have set up increment bar, when dovetail groove is darker, after montant can being disassembled, then increment bar is mounted in montant, in increasing, surveys the length of both sides.
The invention has the beneficial effects as follows: comprise cross bar by internal measure-hand, and the montant be connected with cross bar, described internal measure-hand cross bar is connected in inverted "L" shaped with montant; The measuring surface of described internal measure-hand is equipped with spherical survey block; Vernier caliper can be made to measure the internal diameter of dovetail groove fast.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Wherein: Fig. 1 is the structural representation of measurement dovetail groove required for the present invention;
Fig. 2 is the first embodiment structural representation of the present invention;
Fig. 3 is the second embodiment structural representation of the present invention;
In accompanying drawing, 1 is main scale, and 2 is the secondary chi of vernier, and 3 is internal measure-hand, and 4 is external pelivimetry pawl, and 5 is cross bar, 6 is montant, and 7 is spherical survey block, and 8 is the first threaded hole, and 9 is upper montant, and 10 is the first stud, 11 is lower montant, and 12 is increment bar, and 13 is the second stud, and 14 is the second screw, and 15 is dovetail groove.
Embodiment
The first embodiment of the present invention, as Figure 1-Figure 2, Novel vernier caliper, comprises main scale 1, and the secondary chi 2 of the vernier that can slide on main scale 1; Described main scale 1 and the secondary chi 2 of vernier are provided with two secondary movable measuring jaws, and two secondary movable measuring jaws are respectively internal measure-hand 3 and external pelivimetry pawl 4; Described internal measure-hand comprises cross bar 5, and the montant 6 be connected with cross bar 5, and described internal measure-hand cross bar 4 is connected in inverted "L" shaped with montant 6; The measuring surface of described two internal measure-hand is equipped with spherical survey block 7.
During measurement, now two internal measure-hand are put into dovetail groove 15, by the spherical survey block of internal measure-hand on main scale and dovetail groove one side contacts; Stir the internal measure-hand on the secondary chi of vernier again, make the internal measure-hand on the secondary chi of vernier slide into the opposite side of dovetail groove and be in contact with it; Finally read the reading of vernier caliper.
Preferably, adopt between described spherical survey block 7 and the cross bar 5 of internal measure-hand and be threaded.
It is low that the degree of depth due to dovetail groove has height to have, and when when darker dovetail groove, the degree of depth of internal measure-hand is limited; For the problems referred to above, the second embodiment of the present invention, shown in Figure 2, described internal measure-hand montant 6 comprises with the upper montant 9 of the first screw 8 and the lower montant 11 with the first stud 10, and is connected with increment bar 12 between upper montant and lower montant; Described increment masthead end is provided with second stud 13 that can insert in the first screw, described increment bar bottom be provided with the first stud with the use of the second screw 14; Described first screw size is identical with the second screw.Because the montant central authorities at internal measure-hand have set up increment bar, when dovetail groove is darker, after montant can being disassembled, then increment bar is mounted in montant, in increasing, surveys the length of both sides.
Preferably, the connection between described increment bar and upper and lower montant can adopt clamping, and what the connection between described upper montant to lower montant was corresponding also should adopt clamping.
