Abstract
The utility model discloses a coarse pitch thread profile gauge rule, including leading to rule and no -go gage, lead to rule and no -go gage all including examining a seat, tooth form board and clamp plate, the tooth form board is fixed on examining a seat through the clamp plate, lead to rule and no -go gage to examine a seat the same with the clamp plate, two tooth form distances between plates of expert's rule are according to the biggest confirmation of size of screw thread product, two tooth form distances between plates of no -go gage are according to the minimum confirmation of size of screw thread product. Compared with the prior art, the utility model has the advantages that: can carry out the judgement of according with nature of product with adopting the general accuracy of thread of examining the relatively more difficult coarse pitch product that detects of utensil to adopt the quick test of this device to come out. And detection efficiency is high, is fit for big measuring in batches. It is accurate to detect, and manual operation error influence is little.
Description
Technical field
The utility model relates to a kind of accuracy of thread pick-up unit of steep-pitch thread product, especially relates to a kind of accuracy of thread pick-up unit being widely used in the steep-pitch thread product of rail fastener.
Background technology
The detection of steep-pitch thread product accuracy of thread is more difficult, adopt universal check tool (such as vernier caliper, universal protractor) to measure, because detection reference is not easily control, two parts position, screw thread left and right is uncontrollable, detection difficult, and detection efficiency is low.Because steep-pitch thread product is large quantities of for products such as rail fasteners, batch is larger, need the quantity of detection also larger, adopt universal check tool cannot meet the needs of production in enormous quantities, and it is large to adopt universal check tool operation to control difficulty, testing result subjective factor is comparatively large on assay impact, high to reviewer's operation requirements.
Utility model content
The utility model overcomes shortcoming of the prior art, provides a kind of steep-pitch thread profile board.
The technical solution of the utility model is: a kind of steep-pitch thread profile board, comprises drift and no-go gage, and drift and no-go gage include cubing seat, tooth form plate and pressing plate, and described tooth form plate is fixed on cubing seat by pressing plate; Described drift is identical with pressing plate with the cubing seat of no-go gage, and two pieces of tooth form distances between plates of drift are determined according to the full-size of screw product, and two pieces of tooth form distances between plates of no-go gage are determined according to the minimum dimension of screw product.
Compared with prior art, the utility model has the advantages that: the accuracy of thread of the coarse pitch product adopting the more difficult detection of universal check tool can be adopted the quick test of this device out, carry out product conformity judgement.And detection efficiency is high, be applicable to mass detection.Detect accurately, manual operation error effect is little.
Accompanying drawing explanation
The utility model illustrates by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the structural representation of drift;
Fig. 2 is the structural representation of no-go gage;
Fig. 3 is the schematic diagram of product by drift;
Fig. 4 is that product is not by the schematic diagram of no-go gage.
Embodiment
A kind of steep-pitch thread profile board, as shown in Figures 1 to 4, comprise: drift and no-go gage two parts, every part includes cubing seat 1, tooth form plate 2 and pressing plate 3, and drift is identical with pressing plate 3 with the cubing seat 1 of no-go gage, the tooth form size of tooth form plate 2 is different with length, wherein: the tooth form of drift is complete product tooth form, and length is not less than 5 complete pitch, and no-go gage tooth form is slightly shallow, be about product 2/3 tooth high, length is 2 complete pitch.Two pieces of tooth form distances between plates of drift are determined according to product screw thread full-size, and two pieces of tooth form distances between plates of no-go gage are determined according to product screw thread minimum dimension.
Described cubing seat 1 is the matrix of testing tool, is fixed on cubing seat 1 by left and right tooth form plate 2, and adjusts required size according to product accuracy of thread by pressing plate 3.Drift and no-go gage need to determine that the tooth form angle of tooth form plate, the degree of depth (tooth is high) and crest are wide.The angle of drift tooth form screw die type is consistent with product with Ya Gao size, the wide crest for product of crest is wide add pitch cumulative errors and preset clearance (for the interference avoided because lead angle and tooth form plate thickness produce and reserve) sum; The tooth form screw die type angle of no-go gage is wide with crest consistent with the tooth form plate of drift, tooth height be product tooth high 2/3.
Principle of work of the present utility model is: design in advance processes the thread profile gauge matched with steep-pitch thread, drift meets screw thread maximum material size, no-go gage meets screw thread least material size, is limited by the relative position of left and right tooth form plate to the large footpath of coarse pitch product threaded portion, central diameter, pitch, form of thread, left and right tooth form.
When the accuracy of thread size of steep-pitch thread product is detected:
1) drift using method:
Form of thread drift is kept flat on the table, in the product tooth form groove formed by the two tooth form plates shown in Fig. 3, test product being put into drift, if product threaded portion can pass through drift, then rotating product, is then qualified when other any direction all can pass through drift.Notice that thread tooth direction is consistent with drift in use.
2) no-go gage using method:
Form of thread no-go gage is kept flat on the table, in the product tooth form groove formed by the two tooth form plates shown in Fig. 4, test product being put into no-go gage, if product threaded portion can pass through no-go gage, then rotate product, at other any direction all not by being then qualified during no-go gage.Notice that thread tooth direction is consistent with no-go gage in use.
3) as fruit product threaded portion can pass through screw thread drift completely, and not by screw thread no-go gage, then product accuracy of thread size qualification, otherwise be defective.
Claims (3)
1. a steep-pitch thread profile board, is characterized in that: comprise drift and no-go gage, and drift and no-go gage include cubing seat, tooth form plate and pressing plate, and described tooth form plate is fixed on cubing seat by pressing plate; Described drift is identical with pressing plate with the cubing seat of no-go gage, and two pieces of tooth form distances between plates of drift are determined according to the full-size of screw product, and two pieces of tooth form distances between plates of no-go gage are determined according to the minimum dimension of screw product.
2. steep-pitch thread profile board according to claim 1, is characterized in that: the tooth form angle of described drift tooth form plate is identical with screw product with Ya Gao size, wide wide pitch cumulative errors and the preset clearance sum of adding of crest for screw product of crest; The tooth form angle of described no-go gage tooth form plate is wide identical with drift tooth form plate with crest, tooth height be screw product tooth high 2/3.
3. steep-pitch thread profile board according to claim 1, is characterized in that: the length of described drift tooth form plate is more than or equal to 5 complete pitch; The length of described no-go gage tooth form plate is 2 complete pitch.
