Abstract

The utility model provides a modular slide caliper, it is including being carved with the main scale 1 of millimeter scale, the cover be carved with the vernier 6 of mantissa below the millimeter on the main scale 1, be in the main scale 1 inslot with vernier 6 synchronous gliding degree of depth chi 5, install at vernier 6 upside and downside locking screw 4, become two holistic hook-shaped with main scale 1 and vernier 6 and go up measuring feet 2, 3 and two hook-shaped measuring feet 7, 8 down. The two hook-shaped lower measuring feet 7 and 8 can measure the wall thickness of any part of the bottle-shaped drum-shaped object and the width of the middle layer of a rolled object such as a strip steel coil, and the two hook-shaped upper measuring feet 2 and 3 can measure the inner diameter of any part of the bottle-shaped drum-shaped object. Is a novel combined vernier caliper integrating the characteristics of an inner caliper and an outer caliper.

Description

The combined cursor slide calliper rule

The utility model relates to a kind of combined cursor slide calliper rule.

Now there is certain limitation in the vernier caliper that generally uses when the Measuring Object size, as doleiform, cydariform object bottleneck and two is little, the middle part is big often, can't measure internal diameter, the wall thickness at its middle part; The rolling article are often not concordant as the limit portion of band coil of strip, measure the then necessary uncoiling of middle layer width of steel band of band coil of strip; Or the like.When running into above-mentioned situation, people can expect utilizing inside and outside card to measure very naturally, promptly block the size of testee with inside and outside card, be fetched into again and measure its size on the gage, can be maintained fixed on the basis of invariable but the possibility of so measuring is based upon inside and outside being stuck in the taking-up process.When card is surveyed its internal diameter in running into above-mentioned doleiform or drum body and function because bottleneck or two area of beds are less than the middle part size, in be stuck in and can't keep card directly constant in the taking-up process; In like manner, when measuring the middle layer width of steel band of band coil of strip with wild card,, thereby also can't measure keeping under the constant prerequisite in card footpath wild card taken out because whole winding steel forms the circle of a closure.

The purpose of this utility model is to provide a kind of inside and outside card characteristics that combine itself, the combined cursor slide calliper rule that can effectively measure as the middle layer width of band coil of strip internal diameter, wall thickness and the rolling article of doleiform, cydariform object.

The purpose of the utility model combined cursor slide calliper rule be achieved in that with two of the vernier caliper of prior art go up survey the pin lengthening, outside hook-type is made in the end, makes it to become card shape in; Inside hook-type is made in survey pin lengthening, end under two, makes it to become a wild card shape; Then move equidistantly to vernier one side according to the spacing size that two following interior clasp joints of surveying pin touch latter two foot lever the zero point of main scale high scale.

The utility model combined cursor slide calliper rule compared with prior art have following characteristics:

1. to survey pin be interior card shape because two of the combined cursor slide calliper rule go up, and when measuring doleiform, cydariform object internal diameter, can directly read measured value after snapping in, thereby solve the problem that existing vernier caliper can't be measured doleiform, cydariform object internal diameter;

Since two of the combined cursor slide calliper rule to survey pin down be the wild card shape, when measuring the rolling article, also can block and directly read measured value, thereby realize measurement rolling article middle layer width as the middle layer width of band coil of strip; Survey the measurement that pin also can be finished doleiform, any position of cydariform object wall thickness down for two simultaneously.

Below in conjunction with accompanying drawing the utility model combined cursor slide calliper rule are done detailed description.

Fig. 1 is the front view of the utility model combined cursor slide calliper rule, also is specification digest accompanying drawing of the present utility model.

1 is main scale among Fig. 1, and 2 is to survey pin on the hook-type that is fixed on the main scale, and 3 is to survey pin on the hook-type that is fixed on the vernier, and 4 is lock-screw, and 5 is pit gauge, and 6 is vernier, and 7 for being fixed on survey pin under the hook-type on the vernier, and 8 is to survey pin under the hook-type that is fixed on the main scale.Be carved with a millimeter scale on the main scale 1, the vernier 6 that is carved with the following mantissa of millimeter is enclosed within on the main scale 1, the pit gauge 5 that slides synchronously with vernier 6 is contained in the groove of main scale 1, on the vernier 6, following both sides are equipped with a lock-screw 4 respectively, the hook-type that is fixed on surveying pin 2 on the hook-type on the main scale and being fixed on main scale is surveyed 1 one-tenth integral body of pin 8 and main scale down, being fixed on the hook-type on the vernier hook-type on surveying pin 3 and being fixed on vernier, to survey pin 7 down whole with 6 one-tenths of verniers, and down survey spacing size that the interior clasp joint of pin 7 and the hook-type that be fixed on main scale under survey pin 8 touch latter two foot lever and to vernier 6 one sides move equidistantly according to being fixed on hook-type on the vernier zero point of main scale 1 high scale.

Claims

1. combined cursor slide calliper rule, by main scale (1), be fixed on and survey pin (2) on the hook-type on the main scale, be fixed on and survey pin (3) on the hook-type on the vernier, lock-screw (4), pit gauge (5), vernier (6), be fixed on the hook-type of surveying pin (7) under the hook-type on the vernier and being fixed on the main scale and survey pin (8) composition down, it is characterized in that being carved with a millimeter scale on the main scale (1), the vernier (6) that is carved with the following mantissa of millimeter is enclosed within on the main scale (1), the pit gauge (5) that slides synchronously with vernier (6) is contained in the groove of main scale (1), on the vernier (6), following both sides are equipped with a lock-screw (4) respectively, the following pin (8) of surveying of hook-type that is fixed on surveying pin (2) on the hook-type on the main scale and being fixed on main scale becomes whole with main scale (1), be fixed on hook-type on surveying pin (3) on the hook-type on the vernier and being fixed on vernier and survey down pin (7) and becomes whole with vernier (6), move equidistantly to vernier (6) one sides according to being fixed on the spacing size that interior clasp joint that hook-type on the vernier surveys pin (7) down and be fixed on survey pin (8) under the hook-type on the main scale touches latter two foot lever the zero point of main scale (1) high scale.
