Description
Technical field
The utility model is related to a kind of accuracy of thread comprehensive detection measurers of sawtooth pattern king-bolt screw product, especially relate to
And a kind of accuracy of thread comprehensive detection measurer for the B30 series of products being widely used in railway switch fastener.
Background technology
Now with the development of China railways, B30 series bolts (structure is as shown in Figure 1) are widely used.B30 series spiral shells
Line belongs to sawtooth tooth form, and screw pitch is bigger, and the pitch diameter of thread and screw pitch are also without corresponding special gauge；Usual screw pitch uses
Calliper, and the pitch diameter of thread then uses universal tool-measuring microscope to measure.When using general gage measuring, checks difficult and examine
It is very low to test efficiency, especially checks that not only measuring speed is slow but also human error is not easy to control for general gage measuring when screw pitch,
Some pole upper limits and the size of pole lower limit is caused to there is dispute and erroneous judgement when judging qualified and underproof.
Invention content
The shortcomings that the utility model is overcome in the prior art provides a kind of sawtooth pattern king-bolt accuracy of thread synthesis inspection
Tool, according to the bound of the screw pitch of bolt and the pitch diameter of thread, processes the drift and no-go gage of corresponding size, product size is quantified
Characteristic be converted into qualitative characteristic, the efficiency of inspection is not only increased during production testing, and avoid because measure
Erroneous judgement caused by error and human error and dispute, as long as can meet can lead to can stop accuracy of thread as long as be qualified；As long as logical only have
One unqualified then disqualified upon inspection.
The technical solution of the utility model is：A kind of sawtooth pattern king-bolt accuracy of thread comprehensive check tool, including drift and only
Rule, the drift and no-go gage include cubing seat and two pieces of castellated plates being arranged in the upper and lower card slot of cubing seat, the drift
Two pieces of castellated plates are processed into according to the screw pitch of bolt product and the maximum limit of size of the pitch diameter of thread, and two pieces of castellated plates are constituted
Effective thread be 5 button, tooth form angle and Ya Gao sizes are consistent with bolt product；Two pieces of castellated plates of the no-go gage are according to bolt
The screw pitch of product and the minimum limit of size of the pitch diameter of thread are processed into, and the effective thread that two pieces of castellated plates are constituted is 3.5 buttons,
Tooth form angle is consistent with bolt product, a height of bolt product tooth of tooth it is high 2/3.
Compared with prior art, the utility model has the advantages that：
The utility model is not only simple in structure conducive to operation and reduces the human error of product measurement, sawtooth pattern king-bolt
The accuracy of thread comprehensive detection measurer of screw product utilizes the screw pitch of product screw thread and the tolerance of the pitch diameter of thread and product screw thread
Tooth form designs processing, and control product is qualified in its margin of tolerance (can lead to can stop) when measurement, the screw thread product is smart
The quantitative performance of degree is converted into qualitative characteristics.The utility model effectively raises the inspection speed of product, also avoids because surveying
Measure erroneous judgement caused by error and human error and dispute.
Description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is the structural schematic diagram of B30 series bolt products；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the fundamental diagram of the utility model.
Specific implementation mode
A kind of sawtooth pattern king-bolt accuracy of thread comprehensive check tool, as shown in Fig. 2, including：Cubing seat 1, castellated plates 2, pressing plate 3
With bolt 4 etc., wherein：
After a kind of wear-resisting raw material heat treatment, two sides is polished into end face, according in the screw pitch of bolt, product screw thread
The maximum limit of size of diameter is processed into two plate castellated plates of drift, and the effective thread that two pieces of castellated plates are constituted is 5 buttons, thread form angle
Degree and the high size of tooth are consistent with product；It is processed into no-go gage according to the minimum limit of size of the screw pitch of bolt and the product pitch diameter of thread
Two plate castellated plates, and the effective thread that two pieces of castellated plates are constituted is 3.5 buttons, tooth form angle is consistent with product, and tooth height is about product
Tooth it is high 2/3.
In order to easy to assembly, the installation position of flute profile board slot in the horizontal direction above the cubing seat 1 of drift and no-go gage
Moved to right 0.5P (P is screw pitch) compared to following flute profile board slot, after loading onto between two blocks of flute profile plates after difference 0.5P just and bolt
The screw thread of itself matches.
Structure connects：1. the castellated plates 2 to match with screw thread that design processes first are placed on the card slot of cubing seat 1 (i.e.
Flute profile board slot) in, the screw pitch of flute profile plate is the screw pitch of product, and the angle of flute profile plate flute profile is processed according to the tooth form angle of product
(30 ° and 45 °, as shown in Figure 2)；2. pressing plate 3 is placed on above castellated plates 2, then castellated plates 2 and pressing plate 3 are linked with bolt 4
(increase a spring washer between each bolt 4 and pressing plate 3) on cubing seat.3. accurate adjustment is whole under universal tool-measuring microscope
Screw pitch in drift and no-go gage makes the screw pitch of drift and no-go gage match with product, and the central diameter size of drift is product screw thread
The maximum of central diameter, the central diameter size of no-go gage are the minimum of the product pitch diameter of thread.4. screwing up with a wrench bolt 4 after adjusting i.e.
It can.
Operation principle (as shown in Figure 3)：Accuracy of thread comprehensive detection measurer is put, accuracy of thread is carried out on the table
It checks.1. product is rotated after the threaded portion of bolt is put into drift tooth form, if the threaded portion of bolt is in other arbitrary sides
It is on the contrary to the screw pitch qualification and the pitch diameter of thread for when can pass through drift, then illustrating bolt not above the value of reaching the standard grade of the pitch diameter of thread
It is then unqualified.2. product is rotated after the threaded portion of bolt is put into no-go gage tooth form, if the threaded portion of bolt is at other
Meaning direction cannot then illustrate offline value of the pitch diameter of thread not above the pitch diameter of thread by no-go gage, on the contrary then unqualified.3. simultaneously
Meet 1., it is 2. qualified when product accuracy of thread just calculate qualification, have a unqualified then product accuracy of thread unqualified.
