The purpose of this utility model is completed by following technical solution, a kind of for vernier caliper measurement deep trouth
Measuring head, it includes that a pair of cylindric measuring head and annular knurl brass screw, the cylindric measuring head are separately mounted to vernier caliper
Card base on, be maintained at the bulb center of two cylindric measuring heads on same straight line, and after adjusting use annular knurl copper
Screw locking.
As preferred: the cylindric measuring head includes the rod-shaped measure-ball of front end and the fixation cylinder of rear end,
One is provided on the fixed cylinder to set for fixing the lateral mounting hole of vernier caliper card base, and in the end face of fixed cylinder
It is equipped with the screw hole of axial connection lateral mounting hole, the annular knurl brass screw for locking vernier caliper card base is screwed in screw hole.
As preferred: the vernier caliper is the single side measuring jaw vernier caliper of 0-200,0-300 or 0-500;Described
Lateral mounting hole is the square hole for being made into the conical surface on one side, and the size of the square hole and card base fit clearance are 0.02mm, square hole
Symmetry is controlled in 0.02mm.
The utility model is the repacking carried out on the basis of existing technology, is able to solve that narrow space, groove width be small, trough
Deep some parts measurement problems, are expanded by the function to common calliper, with most economical manufacturing cost, are utilized
The general sexual clorminance of vernier caliper, repacking, which becomes one kind, can measure inner groove and outer groove, and measurement accuracy and vernier caliper are protected
It holds consistent it is ensured that measurement accuracy is consistent with vernier caliper;If replacing different types of measuring head, can be installed to other
On the vernier caliper of specification, the ability of measurement part groove depth is greatly expanded;With make it is simple, easy to install and use, be easy to push away
Extensively, it is very suitable to the features such as mechanical processing industry uses.

Specific embodiment
The utility model is described in detail below in conjunction with attached drawing: shown in Fig. 4, a kind of use described in the utility model
In the measuring head of vernier caliper measurement deep trouth, it includes a pair of cylindric measuring head 2 and annular knurl brass screw 1, the cylindric survey
Amount head 2 is separately mounted on the card base of vernier caliper 3, so that the bulb center of two cylindric measuring heads 2 is maintained at same straight
On line, and locked after adjusting with annular knurl brass screw 1.
As shown in the figure, the cylindric measuring head 2 includes the rod-shaped measure-ball 5 of front end and the fixation cylinder of rear end
6, one is provided on the fixed cylinder 6 for fixing the lateral mounting hole 7 of 3 card base of vernier caliper, and in fixed cylinder 6
End face is provided with the screw hole 8 of axial connection lateral mounting hole 7, and the rolling for locking 3 card base of vernier caliper is screwed in screw hole 8
Flower brass screw 1.
Vernier caliper 3 described in the utility model is the single side measuring jaw vernier caliper of 0-200,0-300 or 0-500;It is described
Lateral mounting hole 7 be the square hole for being made into the conical surface on one side, and the size of the square hole and card base fit clearance are 0.02mm, square hole
Symmetry control in 0.02mm.
Embodiment: shown in Fig. 4, a kind of measuring head for vernier caliper measurement deep trouth, it includes one columned interchangeable
Measuring head 2, annular knurl brass screw 1.Every secondary needs 2 every kind, pairing use.
Shown in Fig. 4, the measuring head can select 0-300mm single side measuring jaw vernier caliper, the card base of the vernier caliper 2
It is long, therefore the measurement range after repacking is bigger, is suitble to the various inside and outside deep annular grooves of measurement.The measuring head is detachable knot
