Abstract
The utility model provides a pitch measurement anchor clamps of screw rod class part, the anchor clamps body of these measurement anchor clamps is plane bases that match with screw rod part length, there is fore -and -aft spout on the base of plane, it contains the supporting shoe that the V type held in the palm the groove still to be equipped with two, be equipped with a fixed position seat and a plurality of fixed inspection seat in one side of spout, to be surveyed the screw rod arranges in on the V type support groove of measuring the anchor clamps supporting shoe, measure the clearance between slide orientation seat pick -up plate and the fixed inspection seat, judge the pitch error of being surveyed the screw rod according to this.
Description
Technical field
The application relates to a kind of parts measurement technology, specifically a kind of pitch measurement fixture of spiral shell component of rod category.
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 transmission, and need through normalizing, carburizing, quenching, the multiple heat process such as tempering, and due to spiro rod length longer, required precision is higher, screw thread process difficulty is also larger, therefore in machining and heat treatment process, often due to Stress Release, the factors such as change in organization, produce screw rod distortion and extend, shorten or bend, so just need a convenience, fast, pitch measurement method accurately, to ensure to meet drawing requirement, and there is no such survey tool at present, need to measure with measuring machine or by lathe, waste time and energy, have a strong impact on the delivery progress of part.
Summary of the invention
The object of the present invention is to provide a kind of pitch measurement fixture of spiral shell component of rod category.
A kind of pitch measurement fixture of spiral shell component of rod category, it is characterized in that the clamp body of this measured material is a flat base mated with Screw Parts length, flat base has longitudinal chute, also be provided with two back-up blocks containing V-type bracket, the line of the V-type bracket of two back-up blocks is parallel with chute, a stationary positioned seat and multiple fixed inspection seat is provided with in the side of chute, described stationary positioned seat is positioned at one end of clamp body, it is provided with telescopic 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 a T-shaped seat of standard, fixed inspection seat is fixed on the standard pitch length dimension position apart from stationary positioned seat some, also has a slip positioning seat, this slip positioning seat is embedded in the chute of flat base by slide block, slip positioning seat is provided with telescopic alignment pin, the front end of this alignment pin is circular arc type probe equally, slip positioning seat is also hinged with a check-out console.
During use, tested screw rod is placed on the V-type bracket of measured material back-up block, the circular arc type probe on stationary positioned seat is put in the groove of screw flight; Slip positioning seat is moved to certain fixed inspection seat place along chute, the circular arc type probe on slip positioning seat is put in the groove of screw flight, check-out console is gone to the side of fixed inspection seat; Measure the gap between check-out console and fixed inspection seat, judge the pitch error of tested screw rod according to this.
The advantage of the application: measured material can realize in production scene convenient, fast, measure pitch length scale error accurately, both saved screw rod to have enough to meet the need back and forth because needs measure, the human and material resources caused, the waste of financial resources, in turn save the time, ensure that manufacturing schedule, also because of convenient, fast and repetitive measurement, avoid finally because tolerance adds up overproof, cause unnecessary scrapping.
Below in conjunction with embodiment accompanying drawing, the application is described in further detail:
Accompanying drawing explanation
Fig. 1 is tested Screw Parts signal
Fig. 2 is the pitch measurement method signal of screw rod
Number description: 1 clamp body, 2 back-up blocks, 3 alignment pins, 4 stationary positioned seats, 5 fixed inspection seats, 6 check-out consoles, 7 slip positioning seats, 8 chutes, 9 screw rods
Detailed description of the invention
See accompanying drawing, the measured material of spiral shell component of rod category pitch, the clamp body 1 of this measured material is a flat base mated with screw rod 9 part length, flat base has longitudinal chute 8, also be provided with two back-up blocks 2 containing V-type bracket, the line of the V-type bracket of two back-up blocks is parallel with chute 8, a stationary positioned seat 4 and multiple fixed inspection seat 5 is provided with in the side of chute 8, described stationary positioned seat 4 is positioned at one end of clamp body 1, it is provided with telescopic alignment pin 3, the front end of this alignment pin 2 is circular arc type probes, can put in the thread groove of screw rod 9, described fixed inspection seat 5 is the T-shaped seats of standard, fixed inspection seat is fixed on the standard pitch length dimension position apart from stationary positioned seat 4 some, (as: fix a fixed inspection seat 5 apart from stationary positioned positioning seat 4 every ten standard pitches.) also have a slip positioning seat 7, this slip positioning seat 7 is embedded in the chute 8 of flat base by slide block, slip positioning seat 7 is provided with equally telescopic alignment pin 3, the front end of this alignment pin 3 is circular arc type probe equally, slip positioning seat 7 is also hinged with a check-out console 6.
When measuring screw rod, tested screw rod 9 is placed on the V-type bracket of measured material back-up block 2, the circular arc type of the alignment pin 3 on stationary positioned seat 4 probe is put in the groove of screw flight, thus the initial measuring position of standing screw pitch; Again slip positioning seat 7 is moved to fixed inspection seat 5 place along chute 8, the circular arc type of the alignment pin 3 on slip positioning seat 7 probe is put in the groove of screw flight, check-out console 6 is gone to the side of fixed inspection seat; Finally with micrometer or the gap between kind of calliper check-out console 6 and fixed inspection seat 5, judge the pitch error of tested screw rod according to this, the gap size of this measurement and gauged distance size comparison can draw the error amount of pitch dimension and drawing.
The application does not need manufacturer's standard screw rod to be used for contrasting, do not need special material to manufacture yet, height is not more needed to go accurately to portray size scale line, it instead of graduation mark with inspection seat, overcoming frock cannot the difficulty of precise marking size scale line, also overcome the length accumulated error of graduation mark, achieve simply, the high object measuring the pitch dimension of long bolt accurately easily and efficiently.
The application utilizes and pops one's head in the supporting circular arc type of screw thread the accurate location determining pitch, overcomes screw rod owing to producing oxide skin after heat treatment, cannot the difficult point of accurate fixed pitch position, ensure that the accurate measurement of screw rod.
The frock material of the application can select not yielding, wear-resisting steel material as required.
The size of the application can be selected voluntarily according to the length of screw rod and pitch dimension, and guarantees that frock can play the parts that will support by long term support, durable in use, not easily formation abrasion etc.
Connection between each parts of the application, can select the mode that bolt connection, welding and bearing slide as required.
