Description
Technical field
The application is related to a kind of parts measurement technology, and specifically a kind of pitch measurement method of spiral shell component of rod category and measurement are pressed from both sides
Tool.
Background technology
Ordinary circumstance, for the long bolt class part of similar Fig. 1, in order to reach surface abrasion resistance, core is tough, accurate biography
Dynamic, and need heat treatment multiple through normalizing, carburizing, quenching, tempering etc., and because spiro rod length is longer, required precision is higher,
Screw thread process difficulty is also larger, therefore in machining and heat treatment process, often due to Stress Release, change in organization etc. because
Element, produces screw rod deformation and extends, shortens or bend, be so accomplished by a convenient, fast, accurately pitch measurement method,
To ensure compliance with drawing requirement, and currently without such survey tool, need with measuring machine or measure by lathe, time-consuming
Arduously, have a strong impact on the delivery progress of part.
Content of the invention
It is an object of the invention to provide a kind of pitch measurement method of spiral shell component of rod category and measured material.
A kind of pitch measurement method of spiral shell component of rod category it is characterised in that: 1) have a measured material, this measured material
Clamp body is a flat base mating with Screw Parts length, has longitudinal chute on flat base, is additionally provided with two
Support block containing V-shaped bracket, the V-shaped bracket of two support blocks line parallel with chute, be provided with one in the side of chute
Stationary positioned seat and multiple fixed inspection seat, described stationary positioned seat is located at one end of clamp body, is provided with scalable thereon
Alignment pin, the front end of this alignment pin is circular arc type probe, can put in screw flight groove, described fixed inspection seat is one
Individual standard t type seat, fixed inspection seat is fixed at stationary positioned seat a number of standard pitch length dimension position, also
There is a slip positioning seat, this slip positioning seat is embedded in the chute of flat base by slide block, slip positioning seat is installed
There is telescopic alignment pin, the front end of this alignment pin is equally circular arc type probe, and slip positioning seat is also hinged with a detection
Plate；2) tested screw rod is placed on the V-shaped bracket of measured material support block, the circular arc type probe on stationary positioned seat is put in spiral shell
In the groove of bar screw thread；3) by slip positioning seat along chute movement to certain fixed inspection seat at, by the circular arc on slip positioning seat
Type probe puts in the groove of screw flight, detection plate is gone to the side of fixed inspection seat；4) measurement detection plate and fixing inspection
Test the gap between seat, judge the pitch error of tested screw rod according to this.
Advantages of the present invention: measured material can production scene realize convenient, fast, accurately measure pitch length chi
Very little error, had both saved screw rod and had had enough to meet the need back and forth because needing measurement, caused human and material resources, the waste of financial resources, when having saved again
Between it is ensured that manufacturing schedule, also repeatedly measure because convenient, fast, it is to avoid to final on business poor accumulative overproof, cause need not
That wants scraps.
Accompanying drawing is described in further detail to the application with reference to embodiments:
Brief description
Fig. 1 is that tested Screw Parts are illustrated
Fig. 2 is that the pitch measurement method of screw rod is illustrated
In figure numbering explanation: 1 clamp body, 2 support blocks, 3 alignment pins, 4 stationary positioned seats, 5 fixed inspection seats, 6 detection plates,
7 slip positioning seats, 8 chutes, 9 screw rods
Specific embodiment
Referring to accompanying drawing, the pitch measurement method of spiral shell component of rod category as shown in the figure.
There is a measured material first, the clamp body 1 of this measured material is a plane mated with screw rod 9 part length
Pedestal, has longitudinal chute 8 on flat base, is additionally provided with the V-shaped of two 2, two support blocks of support block containing V-shaped bracket
The line of bracket is parallel with chute 8, is provided with a stationary positioned seat 4 and multiple fixed inspection seat 5 in the side of chute 8, described
Stationary positioned seat 4 be located at clamp body 1 one end, telescopic alignment pin 3 is installed thereon, the front end of this alignment pin 3 is round
Camber is popped one's head in, and can put in the thread groove of screw rod 9, described fixed inspection seat 5 is a standard t type seat, fixed inspection seat
It is fixed at a number of standard pitch length dimension position of stationary positioned seat 4, (such as: away from stationary positioned seat 4 every ten
Individual standard pitch fixes a fixed inspection seat 5.) also having a slip positioning seat 7, this slip positioning seat 7 is inlayed by slide block
In the chute 8 of flat base, slip positioning seat 7 is equally provided with telescopic alignment pin 3, the front end of this alignment pin 3 is same
Sample is circular arc type probe, and slip positioning seat 7 is also hinged with a detection plate 6.
During detection screw rod, tested screw rod 9 is placed on the V-shaped bracket of measured material support block 2, by stationary positioned seat 4
The circular arc type probe of alignment pin 3 put in the groove of screw flight, thus the initial measurement position of standing screw pitch；Again will
Slip positioning seat 7 moves to a fixed inspection seat 5 along chute 8, and the circular arc type of the alignment pin 3 on slip positioning seat 7 is visited
Head puts in the groove of screw flight, detection plate 6 is gone to the side of fixed inspection seat；Finally use micrometer or kind of calliper inspection
Gap between drafting board 6 and fixed inspection seat 5, judges the pitch error of tested screw rod, the gap size of this measurement and mark according to this
The accurate error amount that can draw pitch dimension and drawing apart from size comparison.
The present invention does not need manufacturer's standard screw rod for contrasting it is not required that special material to manufacture, and less needs high-precision
Accurate go to portray size scale line, it instead of graduation mark with inspection seat, and overcoming frock cannot precise marking size scale line
Difficulty, also overcome the length cumulative error of graduation mark it is achieved that simple, easily and efficiently high accurately measure long bolt
Pitch dimension purpose.
The present invention is popped one's head in determine the accurate location of pitch using the circular arc type supporting with screw thread, overcomes screw rod due to heat
Oxide skin is produced it is impossible to the difficult point of accurate fixed pitch position is it is ensured that the accurate measurement of screw rod after process.
The frock material of the present invention can select to be unlikely to deform as needed, wear-resisting steel material.
The size of the present invention voluntarily can select according to the length of screw rod and pitch dimension, and guarantees that frock being capable of long term support
Act part to be supported, durable in use, it is unlikely to deform abrasion etc..
Connection between each part of the present invention, can select the mode that bolt connection, welding and bearing slide as needed.
