Abstract
The utility model relates to a caliper which comprises a caliper main body, a passing end and a stopping end, wherein the passing end and the stopping end respectively belong to two parts of a clamping groove which is arranged in the caliper. The left side and the right side of a bayonet of the passing end are respectively provided with a hard metal sheet which is connected with the caliper main body in an integrative way. The utility model has the advantages that the left side and the right side of the bayonet of the caliper main body are respectively provided with one hard metal sheet, so that the wear-resisting property of the bayonet material of the caliper is enhanced; the caliper can not easily be damaged because of the wear-resisting property of the bayonet of the caliper, so that the detection accuracy of processing the work piece is enhanced.
Description
[technical field]
The utility model relates to a kind of calliper, especially relates to a kind of cylindrical calliper that detects workpiece accuracy.
[background technology]
Calliper is a kind of testing tool of being used widely, it is the testing tool that is used for detecting the precision and the size of workpiece, existing calliper comprises the calliper body, two parts of the draw-in groove of establishing in the calliper body, end and not-go-end were arranged respectively, cross the bayonet socket and the integrated design of calliper body of end, general 20 Cr-Mn-Tis (20CrMnTi) material that adopts make through osmotic treated, but the hardness of this material is not high, anti-wear performance is poor, be easy to generate wearing and tearing, and the bayonet socket of calliper is place the most easy to wear, therefore, worn out bayonet socket accuracy of detection will descend, and has influenced the batch detection precision of workpiece.
Chinese patent application 02293849 discloses a kind of calliper.The vernier that can slide along main scale that it comprises the main scale that has quiet measuring jaw and has the momentum pawl, quiet measuring jaw and momentum pawl can relative foldings, and described quiet measuring jaw and momentum pawl are curved, and quiet measuring jaw and momentum pawl symmetry, and involutory slit is spindle.
The shortcoming of this patent is the special-purpose calliper of a kind of partes corporis humani of measurement position size, does not fit into to detect processing zero position.
[utility model content]
In order to overcome existing calliper because the bayonet socket material hardness is not high, and anti-wear performance is poor, is easy to generate wearing and tearing, has influenced the shortcoming of workpiece accuracy of detection, the utility model provides a kind of calliper.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of calliper, comprise the calliper body, cross end and not-go-end, cross two parts that end and not-go-end are respectively the draw-in grooves established in the calliper body, each side be provided with a hard metal tip what described mistake was held bayonet socket, the integrated connection between hard metal tip and the calliper body.
Described hard metal tip is connected with the integrated welding manner that is connected between the calliper body.
The beneficial effects of the utility model are: each side be provided with one at bayonet socket and use hard metal tip, improved the anti-wear performance of calliper bayonet socket, because the calliper bayonet socket is wear-resisting, be difficult for being damaged, therefore improved the accuracy of detection of workpiece.
[description of drawings]
Fig. 1 is the structural representation of the utility model calliper.
[embodiment]
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 1, Figure 1 shows that the structural representation of the utility model calliper, a kind of calliper that is used to detect workpiece precision size, central part offers a draw-in groove in calliper body (1), Ka Bi in a side of draw-in groove, draw-in groove is provided with a little circular arc by calliper body (1) apart from outer peripheral 3/2 place, this little arc radius is 0.8mm, little circular arc was end (2) by calliper body (1) outer edge part, little circular arc is not-go-end (3) by the lining part, be respectively equipped with a hard metal tip (4) in the described left and right sides of crossing end (2), hard metal tip (4) is welded on the bayonet socket position of calliper body (1), the integrated connection between hard metal tip (4) and the calliper body (1).Owing to each side be provided with a usefulness hard metal tip (4) at calliper body (1) bayonet socket, thereby improved the anti-wear performance of calliper bayonet socket, because the calliper bayonet socket is wear-resisting, be difficult for being damaged, therefore improved the accuracy of detection of workpiece.
Claims (2)
1, a kind of calliper, comprise the calliper body, cross end and not-go-end, cross two parts that end and not-go-end are respectively the draw-in grooves established in the calliper body, it is characterized in that: each side be provided with one and use hard metal tip at the described bayonet socket of holding of crossing, the integrated connection between hard metal tip and the calliper body.
2, calliper according to claim 1 is characterized in that: described hard metal tip is connected with the integrated welding manner that is connected between the calliper body.
