Abstract

The utility model relates to a combined multipurpose square caliper used for measurement. The utility model is composed of a square caliper (1), an inner caliper (5) and an outer caliper (4). The combined multipurpose square caliper is convenient to disassemble and assemble, and the measured data of the internal and the external dimensions can be read out directly on the vernier caliper. Particularly, the caliper can measure the wall thickness of the workpieces with irregular shape under the condition that the workpieces are not demaged.

Description

Combined multipurpose square calliper
The utility model is a kind of survey instrument, relates to general measurer vernier caliper and inside and outside clamp.
At present in machining is produced, the length and width of testing product, external diameter, internal diameter equidimension vernier caliper commonly used and inside and outside clamp, but this three only can do the detection of simple or regular shape product, inside dimension to the big young container in chamber, curve surface container and irregularly shaped product is then powerless, let alone has directly measured wall thickness.Detect also and must have the inconvenience part when therefore using with inside and outside clamp by means of another root ruler ability sense data.
The utility model is improved at the at present general vernier caliper and the function and the weak point of inside and outside clamp, designs a kind of combined multipurpose measurer simple in structure, easy to use.
This combined multipurpose vernier caliper is made up of vernier caliper (1) and external callipers (4), internal calliper (5).One locating slot (3), a 2-3 screw (2) are arranged on the measuring claw of vernier caliper, internal calliper (5) and external callipers (4) upper end coincide with the measuring claw root shape of vernier caliper (1), and is being processed with the screw of locating slot (6), (7) and equal number with the corresponding position of measuring claw.When needing to survey the outer workpiece size external callipers (4) is installed on the measuring claw of vernier caliper, then internal calliper (5) is installed on the measuring claw of vernier caliper when needing to survey the workpiece inside dimension.After shedding clamp, the original function of vernier caliper (1) is constant.
The utlity model has very high practical value, measurer manufacturer need not to do too big adjustment and can produce, and user's use, easy accessibility, data can directly be read on vernier caliper, also can reduce error simultaneously, improves measuring accuracy.Particularly can solve a difficult problem of under the situation of defective work piece not, measuring irregularly shaped workpiece.
Accompanying drawing 1 of the present utility model is an assembly drawing, among the figure: 1-vernier caliper, 2-screw, 4-external callipers, 5-internal calliper, 6-locating slot.
Accompanying drawing 2 is an A portion enlarged drawing, among the figure: 1-vernier caliper, 2-screw, 3-locating slot, 4-external callipers, 6-locating slot.
Accompanying drawing 3 is that figure cuts open in external callipers part drawing and office, among the figure: 2-screw, 4-external callipers, 6-locating slot.
Accompanying drawing 4 is the internal calliper part drawing, among the figure: 2-screw, 5-internal calliper, 7-locating slot.
Embodiment: the utility model mills out the locating slot (3) that a degree of depth is at least 1mm on every measuring claw of vernier caliper (1), so that clamp can accurately locate, and processes two screws thereon, and the clamp upper end matches with measuring claw root shape.On every clamp upper end and the corresponding position of measuring claw, stamp out locating slot (6), (7) (this location groove width must closely cooperate with the locating slot on the measuring claw, and flute length can be free tolerance).When surveying the outer workpiece size, locating slot (6) bossing on the external callipers (4) is inlayed in the locating slot (3) on vernier caliper (1) measuring claw into, and both are tightened up with screw.The data that external callipers (4) is measured can directly be read from vernier caliper.When surveying the workpiece inside dimension, the internal calliper installation method is identical with the external callipers installation method, and the data of measuring are that the reading on the vernier caliper adds 20mm(again because of two wide 20mm of being of foot-measuring itself).After shedding clamp, the vernier caliper original function is constant.

Claims (1)

  1. A kind of combined multipurpose vernier caliper that is used to measure, form by vernier caliper (1) and external callipers (4), internal calliper (5), it is characterized in that on the measuring claw of vernier caliper a locating slot (3) being arranged, 2-3 screw (2), internal calliper (5) and external callipers (4) upper end coincide with the measuring claw root shape of vernier caliper (1), and is being processed with the screw of locating slot (6), (7) and equal number with the corresponding position of measuring claw.
