Abstract

The utility model discloses a measure percentage table calliper of hole groove footpath, its structure is: the fixed jaw (3) and the movable jaw (4) are respectively connected with the gauge body (1), wherein the fixed jaw (3) is connected with a long hole of the gauge body (1), a spring (2) is also connected between the gauge body (1) and the movable jaw (4), and the gauge body (1) is also provided with a handle (8); the measuring body (1) is connected with a dial indicator (7) through a meter frame (6). Wherein, two handles (8) are arranged on the gauge body (1), one handle is arranged at the joint of the gauge stand (6) and the gauge body (1), and the other handle is arranged at the boss (13) of the gauge body (1). The utility model discloses can measure the diameter of inner hole groove accurately to the reading is convenient, directly perceived, and measurable quantity scope is big. The size of the diameter of the inner hole groove can be accurately measured after the percent ruler is contrasted and corrected through adjustment between the fixed clamping jaw and the movable clamping jaw.

Description

The dial gauge clamp in hole slot footpath in measuring

Technical field

The utility model relates to a kind of survey instrument, particularly relates to the instrument of hole slot in a kind of the measurement.

Background technology

For those narrow and dark inside grooves on the workpiece, in most of the cases, its end, directly can not directly be detected with common calliper.The general transformation of the way vernier caliper that adopts detects in producing at present; If footpath, end dimensional accuracy is low, detects with transformation of the way vernier caliper and can control crudy; If footpath, end dimensional accuracy height, though can detect with transformation of the way vernier caliper, the accuracy of detection of vernier caliper is lower, and measuring error is bigger.

Summary of the invention

The technical problems to be solved in the utility model is: the dial gauge clamp in hole slot footpath in a kind of the measurement are provided, and lower to overcome the accuracy of detection that prior art exists, the deficiency that measuring error is bigger.

The utility model is to constitute like this: stationary jaw, movable jaw are connected with measuring, and wherein stationary jaw is connected with the slotted hole of measuring, also connect spring between measuring and movable jaw, also have handle on measuring; Measuring is connected with dial gauge by dial framework.

Movable jaw is connected with measuring by rivet, and movable jaw is flexible swinging on measuring.

Principle of work is as follows:

Adopt relative method to measure, soon the external diameter Centigrade scale is adjusted by workpiece size and is fixing, clamp make two claws under the effect of spring (be stationary jaw, movable jaw) contacts and adjusts dial gauge with external diameter Centigrade scale measurement face and dial framework makes it to contact with movable jaw, find out minor increment (promptly table clockwise rotates terminal point) with stationary jaw for a spot wobble clamp then, the dial gauge pointer is adjusted to zero-bit, the little pin sensing reading 1 of dial gauge is about dial gauge control stroke 1mm simultaneously), pinch two handles on the clamp with right hand thumb and middle finger during measuring workpieces, and with forefinger promotion activity clamp to dwindle the distance between claw, clamp are sent in the slotted eye, unclamping forefinger makes claw directly contact with bottom land, two claws are ajusted with the side of groove, and be that fulcrum swings up and down and finds out full-size with the stationary jaw, be that indicator rotates counterclockwise terminal point, its difference that points to reading and zero-bit is physical size and the difference that requires size, contact distance is equal with it to the movable jaw distance because of oscillation centre, should notice also at this moment whether little pin points to reading 1.

Notice in the use that stationary jaw must be fastening firm, can not become flexible that movable jaw can center on fulcrum (being the rivet place) and rotate flexibly, interference can not be arranged, but at the rivet place too big gap can not be arranged, otherwise influence measuring stability.Simultaneously, proofread and correct through the external diameter Centigrade scale of corresponding measurement range commonly used.

This measurer applicability is big, but general gaging hole footpath scope is 12-100mm; Also can design, and measuring accuracy is higher, be suitable for very much on-the-spot use of operator and reviewer and detect usefulness, and comparatively robust is durable according to the range of size of product.

Embodiment

Embodiment of the present utility model: as shown in Figure 1 and Figure 2, stationary jaw 3, movable jaw 4 are connected with measuring 1, wherein stationary jaw 3 is connected with the slotted hole of measuring 1, also connects spring 2 between the boss 13 of measuring 1 and movable jaw 4, also has handle 8 on measuring 1; Measuring 1 is connected with dial gauge 7 by dial framework 6.

Wherein, stationary jaw 3 can pass through bolt 9, nut 12 is connected with measuring 1.

For easy to use, two handles 8 are housed on measuring 1, one of them handle is installed in the junction of dial framework 6 and measuring 1, and another handle is installed in boss 13 places of measuring 1.

Movable jaw 4 is connected with measuring 1 by rivet 5, makes movable jaw flexible swinging on measuring.

Dial framework 6 is connected with dial gauge 7 by screwing 10, is connected with measuring 1 by following screw 11.

For durable, the claw tip 14 of stationary jaw 3, movable jaw 4 is created spherical, its radius is R1, promptly radius is 1mm.
