Abstract
A kind of cement overhauls handle neck length measuring device, main measuring claw includes fixed block and positioning column, fixed block is mutually fixed with blade, positioning column is fixed on fixed block, positioning column is vertical with blade, the central axes of positioning column correspond to the zero graduation position of main scale, and the central axes of positioning column are fallen in from the track that measuring claw is slided with vernier scale in axial plane.The axle center of positioning column corresponds to the zero graduation of main scale, and the positioning hole shape that the shape of positioning column overhauls handle with cement is adapted, positioning column need to be only inserted into the location hole that cement overhauls handle when measuring and using, the button resisted from measuring claw, in location hole side wall under the limit guidance of positioning column, it can guarantee that the central axes of positioning column are overhauled at a distance from handle neck length with from the distance between measuring claw as cement to be measured.
Description
Technical field
The utility model relates to the technical field of orthopedic instrument production, specifically a kind of cement overhauls handle neck length measurement dress
It sets.
Background technique
Vernier caliper is generally used to the detection measurement of product in production process, common vernier caliper includes blade, trip
Scale, main scale, the first measuring claw and the second measuring claw, wherein main scale is mutually fixed with blade, shows scale on main scale, vernier scale with
Blade matches to merge to be slided along blade, and the first measuring claw includes the first main measuring claw being arranged in pairs and first from measuring claw, the
Two measuring claws include that the second main measuring claw being arranged in pairs and second are divided from measuring claw, the first main measuring claw and the second main measuring claw
It is not fixedly installed on the two sides of blade, first is fixedly installed on the two sides of vernier scale from measuring claw and second from measuring claw respectively,
The internal diameter of product is measured by the first measurement end that the first measuring claw is formed under normal circumstances, and formed by the second measuring claw
The outer diameter of second measurement end measurement product.
When overhauling handle to cement and detecting, neck length is crucial testing data, and is exactly corresponding to neck length data
Mud overhauls the vertical range of location hole on handle to button top, and in the prior art vernier caliper can not center to location hole and
Button top is accurately positioned, and measurement movement is also just unable to complete.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of cement to overhaul handle neck length measuring device.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique:
The cement of the utility model overhauls handle neck length measuring device, including blade, vernier scale, main scale and measuring claw, wherein
Main scale is mutually fixed with blade, and scale is shown on main scale, and vernier scale merges with blade matching to be slided along blade, and measuring claw includes pairs of
The main measuring claw that is arranged and from measuring claw, main measuring claw is fixed with blade, and is fixed from measuring claw with vernier scale, main measuring claw packet
Fixed block and positioning column are included, fixed block is mutually fixed with blade, and positioning column is fixed on fixed block, and positioning column is vertical with blade, fixed
The central axes of position column correspond to the zero graduation position of main scale, and the central axes of positioning column fall in and slide with vernier scale from measuring claw
In track in axial plane.
The utility model can also use following technical measures:
The positioning column is cylinder, and it is consistent that the shape of positioning column and cement overhaul the positioning hole shape on handle, is positioned
The lower end of column is button-head.
Setting measurement numeric display unit on the vernier scale.
The utility model has the advantages and positive effects of:
The cement of the utility model is overhauled in handle neck length measuring device, and main measuring claw is the positioning column vertical with blade, fixed
The axle center of position column corresponds to the zero graduation of main scale, and the positioning hole shape that the shape of positioning column overhauls handle with cement is adapted,
Positioning column need to be only inserted into cement when using and overhauled in the location hole of handle by measurement, and the button resisted from measuring claw is positioning
Hole side wall is under the limit guidance of positioning column, it can guarantees that the central axes of positioning column are as wanted with from the distance between measuring claw
The cement of measurement overhauls the distance of handle neck length.
Detailed description of the invention
Fig. 1 is that the cement of the utility model overhauls the schematic diagram of handle neck length measuring device；
Fig. 2 be the cement of the utility model overhaul in handle neck length measuring device measurement when schematic diagram.
Specific embodiment
The technical solution of the utility model is described in detail below by way of the drawings and specific embodiments.
As depicted in figs. 1 and 2, the cement of the utility model overhauls handle neck length measuring device, including blade 1, vernier scale 2,
Main scale 3 and measuring claw, wherein main scale is mutually fixed with blade, shows that scale, vernier scale merge with blade matching along blade on main scale
Sliding, measuring claw include the main measuring claw being arranged in pairs and from measuring claw, and main measuring claw is fixed with blade, and from measuring claw with swim
Scale is fixed, and main measuring claw includes fixed block 4 and positioning column, and fixed block is mutually fixed with blade, and positioning column 5 is fixed on fixed block
On, positioning column is vertical with blade, and the central axes of positioning column correspond to the zero graduation position of main scale, and the central axes of positioning column are fallen in
From in the track that measuring claw 6 is slided with vernier scale in axial plane.
Positioning column is cylinder, and it is consistent that the shape of positioning column and cement overhaul 9 shape of location hole on handle 8, positioning column
Lower end is button-head, and when positioning column is inserted into location hole, the side outer wall of positioning column and the inner wall of location hole fit.
The cement of the utility model is overhauled in handle neck length measuring device, and main measuring claw is the positioning column 5 vertical with blade, fixed
The axle center of position column corresponds to the zero graduation of main scale, and the positioning hole shape that the shape of positioning column overhauls handle with cement is adapted,
Positioning column need to be only inserted into cement when using and overhauled in the location hole 9 of handle 8 by measurement, the button 10 resisted from measuring claw,
Location hole side wall is under the limit of positioning column guidance, it can guarantee the central axes of positioning column with from the distance between measuring claw i.e.
The distance of handle neck length is overhauled for the cement to be measured.
Setting measurement numeric display unit 7 on vernier scale, can be by measurement data directly aobvious by numeric display unit
It is shown in display screen, which belongs to the prior art in vernier caliper technology.
