Abstract
The utility model discloses a measuring tool for measuring diameters at the bottoms of an even number of screw spiral grooves. The measuring tool comprises a support pillar, an upper regulating lever and a lower regulating lever, wherein one end of the upper regulating lever and the lower regulating lever is respectively sleeved on the support pillar in a sliding manner and can be locked in a position through a locking part, a dial indicator and a movable measuring bar connected with a pointer of the dial indicator are arranged at the other end of the upper regulating lever, a fixed measuring bar is arranged at the other end of the lower regulating lever, the central lines of the movable measuring bar and the fixed measuring bar are coincided, and spherical contacts are respectively fixed at the lower end of the movable measuring bar and the upper end of the fixed measuring bar. The spherical contacts for the movable measuring bar and the fixed measuring bar are arranged in the position to be tested for the screw, thereby solving the problem of excessively large contact area between the measuring tool and the screw during the measurement, and enhancing the measuring accuracy; and meanwhile, the measured reading can be intuitively displayed through the dial indicator, and the structure is simple and practical.
Description
Technical field
The utility model relates to field of measuring technique, especially a kind of measurer that is used to measure even number head screw rod external spiral groove groover rot diameter.
Background technology
When making or check even number head screw rod, method to the common employing of measurement of its external spiral groove groover rot diameter is to use milscale and vernier caliper, in the actual measurement process, the contact area of these measurers and screw rod is bigger, be difficult for measuring the accurate size of workpiece, also need during reading measurer is taken off the data that just can read measurement from screw rod, directly perceived inadequately, and be easy to generate error.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of measurer of measuring even number head screw spiral trough groover rot diameter is provided, when reduce measuring with the contact area of the screw rod of being surveyed, raising measuring accuracy, and can intuitively show measurement result.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of measurer of measuring even number head screw spiral trough groover rot diameter, comprise pillar, raise pole and lower dolly bar, an end separately that raises pole and lower dolly bar is set in slidably on the pillar and also can be locked in a certain position by locking piece, the movable measuring staff that the other end of rise pole is provided with dial gauge and is connected with the pointer of dial gauge, the other end of lower dolly bar is provided with fixedly measuring staff, movable measuring staff and fixedly the center line of measuring staff coincide, the lower end of movable measuring staff and fixedly the upper end of measuring staff be fixed with spherical contact respectively.
For adapting to the measurement requirement of different size screw rod, described measurer also comprise be used to measure before the check and correction lining bar of spacing between the spherical contact on spherical contact and the fixing measuring staff on the adjusting activity measuring staff, and proofread the screw diameter of the height of lining bar less than measured place.
The beneficial effects of the utility model are: the utility model with movable measuring staff and fixedly the spherical contact of measuring staff place the place to be measured of screw rod, the contact area of measurer and screw rod when having reduced measurement, improved measuring accuracy, simultaneously, movable measuring staff can move freely, can show corresponding reading intuitively by dial gauge, thereby also just can find the smallest point of the screw rod of surveying easily.

Embodiment.
In conjunction with the accompanying drawings the utility model is further described now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of measurer of measuring even number head screw spiral trough groover rot diameter as shown in Figure 1, comprise pillar 1, raise pole 2 and lower dolly bar 3, an end separately that raises pole 2 and lower dolly bar 3 is set on the pillar 1 slidably, and after adjusting to the right place, be fixed on the position by locking piece 4, the movable measuring staff 6 that the other end of rise pole 2 is provided with dial gauge 5 and is connected with the pointer of dial gauge 5, the other end of lower dolly bar 3 is provided with fixedly measuring staff 7, movable measuring staff 6 coincides with the fixing center line of measuring staff 7, the lower end of movable measuring staff 6 and fixedly the upper end of measuring staff 7 be fixed with spherical contact 8 respectively.
As shown in Figure 2, for adapting to the measurement requirement of different size screw rod, this measurer also comprise be used to measure before spherical contact 8 and the fixing check and correction lining bar 9 of spacing between the spherical contact 8 on the measuring staff 7 on the adjusting activity measuring staff 6, and the height of check and correction lining bar 9 is slightly less than the screw diameter at measured place, check and correction lining bar 9 can be designed to seriation by the difference of screw diameter.
During measurement, specification size according to the survey screw rod, choose suitable check and correction lining bar 9, lower dolly bar 3 is fixed on the pillar 1, adjust to raise pole 2 positions, make check and correction lining bar 9 both ends of the surface respectively with movable measuring staff 6 on spherical contact 8 and fixedly the spherical contact 8 on the measuring staff 7 contact, will raise pole 2 and be fixed on the pillar 1, can measure, the height of check and correction lining bar 9 adds that dial gauge 5 data presented are the measured value at the measured place of screw rod.
With above-mentioned foundation embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from the utility model technological thought.Technical scope of the present utility model is not limited to the content on the instructions, must determine its technical scope according to the claim scope.
