Abstract
The utility model relates to a shoulder slot width measuring instrument which comprises a measuring instrument seat, a table setting piece and a reference table. The shoulder slot width measuring instrument is characterized in that a clamping sleeve, a compression spring and a shaft pin-connected lever are arranged on the measuring instrument seat; one end of the lever is provided with a ball contact, and the other end is provided with a flat contact; a measuring rod of the reference table is arranged in the clamping sleeve; and a measuring head is pressed on the flat contact of the lever and is fixed on the measuring instrument seat through a screw. The shoulder slot width measuring instrument provided by the utility model makes use of the lever principle, and has the advantages of simple and compact structure, small volume, low manufacturing cost and convenient operation. When the shoulder slot width of a part with narrow space is measured, a dial gauge or a micrometer gauge can be selected according to the precision requirement, and the practicability is strong. The minimum measurement slot width can reach 5 millimeters. The repeatability is good, and the measurement accuracy is high.
Description
Technical field
The utility model relates to a kind of groove width and measures measurer, is specifically related to a kind of shoulder groove width and measures measurer.
Background technology
In mechanical industry, have the measurement of the shoulder groove width of narrow space part, the one, adopt vernier caliper measurement, measurer is cheap, but measuring accuracy is low, and precision has only 0.02mm, and because vernier caliper foot-measuring size is big, not the groove width in the energy measurement small space; The 2nd, tool microscope, measuring accuracy is high, but price is high, equally also has the big defective of foot-measuring size, designs foot-measuring again, needs to demarcate again, and the high time of expense is long, also can influence measuring accuracy.
Summary of the invention
The purpose of the utility model is exactly to overcome the deficiency that above-mentioned general measurer exists, and provides a kind of easy to manufacture, uses the shoulder groove width easy to operate, that measuring accuracy is high to measure measurer.
The shoulder groove width of the utility model is measured measurer, comprises measurer seat, his-and-hers watches spare, divides kilsyth basalt, it is characterized in that: the lever that described measurer seat is provided with chuck, stage clip and is connected by pivot pin; One end of lever is provided with the ball contact, and the other end is provided with flat contact; Divide the sounding rod of kilsyth basalt to place chuck, measuring head is pressed on the flat contact of lever, is fixed tightly on the measurer seat with screw.
For the better above-mentioned purpose that realizes, described minute kilsyth basalt can be that dial gauge also can be a clock gauge.
The shoulder groove width of the utility model is measured measurer, utilizes lever principle, and is simple and compact for structure, advantages of small volume, and manufacturing expense is low, uses easy to operate; Measure the shoulder groove width of narrow space part, can select dial gauge or clock gauge for use according to accuracy requirement, practical, minimum measurement groove width can reach 5 millimeters, good reproducibility, measuring accuracy height.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, measurer seat, 2, chuck, 3, flat contact, 4, stage clip, 5, straight pin, 6, lever, 7, pivot pin, 8, the ball contact, 9, his-and-hers watches spare, 11, divide kilsyth basalt.
Embodiment
The shoulder groove width of the utility model is measured measurer, comprises measurer seat 1, his-and-hers watches spare 9, divides kilsyth basalt 11.Measurer seat 1 is provided with chuck 2, stage clip 4 and the lever that is connected by pivot pin 76; One end of lever 6 is provided with ball contact 8, and the other end is provided with flat contact 3; Divide the sounding rod of kilsyth basalt 11 to place chuck 2, measuring head is pressed on the flat contact 3 of lever 6, is fixed tightly on the measurer seat 1 with screw.
During use, earlier measurer is placed on the his-and-hers watches spare 9, ball contact 8 is pushed in the groove of his-and-hers watches spare 9, the dial plate that divides kilsyth basalt 11 is to zero; Take off his-and-hers watches spare 9, measurer is placed on the circular bead surface of tested part, ball contact 8 is pushed in the groove of tested part, stage clip 4 promotes lever 6 makes ball contact 8 closely contact with the dial gauge measuring head with measurement face, flat contact 3; Indication numerical value is exactly the actual value of tested part groove width on the branch kilsyth basalt 11, and precision can reach 0.01mm.To divide kilsyth basalt 11 to change the clock gauge precision into and can reach 0.001mm.
Claims (2)
1. a shoulder groove width is measured measurer, comprises measurer seat (1), his-and-hers watches spare (9), divides kilsyth basalt (11), it is characterized in that: the lever (6) that described measurer seat (1) is provided with chuck (2), stage clip (4) and is connected by pivot pin (7); One end of described lever (6) is provided with ball contact (8), and the other end is provided with flat contact (3); Described minute kilsyth basalt (11) measuring staff place chuck (2), measuring head is pressed on the flat contact (3) of lever (6), is fixed tightly on the measurer seat (1) with screw.
