Abstract
The utility model discloses a multifunctional caliper, which comprises a main caliper and a vernier scale, wherein, two clamp feet are formed at the lower parts on one sides of the main caliper and the vernier scale respectively; an auxiliary clamp foot is installed at the lower part of each clamp foot respectively; the two auxiliary clamp feet are positioned in a plane surface perpendicular to the clamp feet and are arranged symmetrically; contour lines of orthographic projections of the two auxiliary clamp feet are two intersecting circles; and a contact surface of the two auxiliary clamp feet is positioned on a common quadrature of the two circles. The multifunctional caliper can measure the sizes of operating internal grooves and external grooves, can be used as a common caliper after the auxiliary clamp feet are dismounted, widens the application range of the common caliper, and is convenient to use.
Description
Technical field
The utility model relates to a kind of survey instrument, particularly relates to a kind of multifuctional calliper.
Background technology
Existing slide calliper rule comprise main scale and vernier scale, generally are used for the internal diameter or the external diameter of measuring workpieces.And under many circumstances, also need measure the inside groove or the water jacket of workpiece.Existing slide calliper rule can not satisfy this measurement demand.
Summary of the invention
The technical matters that the utility model will solve provides a kind of inside groove and the slide calliper rule of water jacket size that can measuring workpieces.
For this reason, the technical scheme of the utility model is following:
A kind of multifuctional calliper; Comprise main scale and vernier scale; The bottom of said main scale and vernier scale one side respectively is formed with a card base, in the bottom of each said card base an auxiliary card base is installed respectively, and said two auxiliary card bases are positioned at the plane vertical with said card base and are symmetrical set; The outline line of two auxiliary card base orthogonal projection is two crossing circles, and the surface of contact of two auxiliary card bases is positioned on the public string of two circles.
When two auxiliary card bases contacted, 0 scale mark of delegation overlapped with 0 scale mark of delegation above the said vernier scale above the said main scale.
The multifuctional calliper of the utility model, inside groove and water jacket size that can surveying work, during the measuring workpieces inside groove, its round auxiliary card base and inside groove are to contact, so can measure the size of workpiece inside groove easily; In addition, card base is that line contacts with work in it, so relatively be fit to measure the narrow workpiece of some water jackets.After laying down auxiliary card base, also can be used as common slide calliper rule and use.
Description of drawings
Fig. 1 is the structural representation of the multifuctional calliper of the utility model;
Fig. 2 is that the A of multifuctional calliper among Fig. 1 is to view.
Embodiment
Be elaborated below in conjunction with the structure of accompanying drawing to the multifuctional calliper of the utility model.
As shown in Figure 1, the multifuctional calliper of the utility model comprises main scale 1 and vernier scale 2.The bottom of main scale 1 and vernier scale 2 one sides respectively is formed with a card base 3, and an auxiliary card base 5 respectively is installed in the bottom of each card base 3.Two auxiliary card bases 5 are positioned at the plane vertical with card base 3 and are symmetrical set, and as shown in Figure 2, the outline line of two auxiliary card base orthogonal projection is two crossing circles, and the surface of contact of two auxiliary card bases is positioned on the public string of two circles.
Referring to Fig. 1, when two auxiliary card bases contacted, 0 scale mark of delegation overlapped with 0 scale mark of delegation above the vernier scale 2 above the main scale 10.
For the ease of dismounting, the center of each auxiliary card base 5 respectively is vertically installed with a mounting rod 4, and mounting rod 4 is fixedly connected with card base 3 through the screw thread jackscrew.
Method of application in the face of this multifuctional calliper describes down.
During use, two auxiliary card bases are fixedly connected with card base 3 through the screw thread jackscrew, can begin to measure inside groove or water jacket size.When measuring water jacket, the interior card base of auxiliary card base is contacted with the outer rooved face of workpiece, can be according to the direct reading of the scale of delegation above the slide calliper rule; When measuring inside groove, two auxiliary card bases are inserted in the inside groove to be measured, the outer card base (being cylindrical) of auxiliary card base is contacted with the interior rooved face of workpiece, behind the scale reading according to delegation above the slide calliper rule, deduct the size of two auxiliary card bases, can obtain the inside groove size.
Claims (2)
1. multifuctional calliper; Comprise main scale and vernier scale; The bottom of said main scale and vernier scale one side respectively is formed with a card base, it is characterized in that: in the bottom of each said card base an auxiliary card base is installed respectively, said two auxiliary card bases are positioned at the plane vertical with said card base and are symmetrical set; The outline line of two auxiliary card base orthogonal projection is two crossing circles, and the surface of contact of two auxiliary card bases is positioned on the public string of two circles.
2. multifuctional calliper according to claim 1 is characterized in that: when two auxiliary card bases contacted, 0 scale mark of delegation overlapped with 0 scale mark of delegation above the said vernier scale above the said main scale.
