Abstract

The utility model discloses a vernier scribing compass which is composed of a main scale, an auxiliary scale, a tight-regulating screw, a pulley wheel and a scriber mechanism. The scriber mechanism is composed of a scriber, a slide block, a tightness-adjustable screw and a retreat stop screw. The utility model which has the advantages of simple structure and convenient operation can serve as the vernier and also the scribing compass for the hole.

Description

Vernier divider caliper for hole

The utility model belongs to a kind of measurement scoring tool.

At present the normal hole of adopting of some factories is that bipod is plan with planing, and this shortcoming of planing is to look for the garden heart in the hole, and common way is to use wood or lead obstruction post hole, garden, and the control board dipstick metering goes out radius and draws the garden then.

The purpose of this utility model provides a kind of simple in structure, and is easy to operate, and the hole of dual-purpose vernier caliper is with planing.

The utility model is achieved like this is in the main scale left end bottom of existing vernier caliper

Respectively bore a blind hole on the two side, a type left side and on the right two side of secondary chi right-hand member bottom ┌ type, the degree of depth of blind hole is greater than the radius of place kick, diameter less than place kick, blind hole and place kick are movingly, load onto place kick, cutter blind hole edge makes the blind hole mouth produce burr so that place kick does not come off, and loads onto scriber mechanism promptly with the afterbody of secondary chi on main scale: scriber, slide block, slack adjuster, stopping screw.

Operating process of the present utility model is as follows: two longitudinal register balls of vernier caliper are stuck on the inside surface in hole, garden, and two located lateral balls are close on the end face in hole, garden, adjust scriber according to the garden of drawing different radii and can draw the garden.

The utility model has the advantages that: simple in structure, easy to operate, vernier calipers can be worked as and the hole can be worked as again with the use of planing.

Below in conjunction with embodiment the utility model is further described:

Fig. 1 is a structural representation of the present utility model.

Referring to Fig. 1, the 1--place kick, the 2--main scale, the secondary chi of 3--, 4--tightens screw, the 5--scriber; The 6--stopping screw; The 7--slide block; The 8--slack adjuster.

Referring to Fig. 1, on the two side 9 of the main scale 2 left end bottom ┐ types of existing vernier caliper and secondary chi 3 right-hand member bottoms

Two side 10 on respectively bore a blind hole, the degree of depth of blind hole is greater than the radius of place kick 1, diameter less than place kick 1, the degree of depth of four blind holes will be within the dimensional accuracy scope of regulation, blind hole and place kick 1 are movingly, load onto place kick 1, cutter blind hole edge, make the blind hole mouth produce burr, on main scale 2, load onto scriber mechanism with the afterbody of secondary chi 3 so that place kick does not come off; That is: scriber 5, slide block 7, slack adjuster 8, stopping screw 6, scriber mechanism adjusts along with drawing a different radii garden.

The hole is as follows with the vernier scale operating process of planing: two longitudinal register balls 1 are stuck on the inside surface in hole, garden, and two located lateral balls 1 are close on the end face in hole, garden, adjust scriber 5 according to the garden of drawing different radii, can draw the garden.

Claims

1, plan with vernier scale in a kind of hole, by main scale, secondary chi, tightens screw, pulley composition, and it is characterized in that: a is equipped with scriber mechanism on main scale; B respectively is equipped with two place kick at the right side wall of the left end bottom of main scale 7 type left side walls and secondary chi right-hand member bottom ┌ type.

2, plan with vernier scale in a kind of hole according to claim 1, it is characterized in that: scriber mechanism is made up of scriber, slide block, slack adjuster, stopping screw.
