Abstract
The utility model belongs to the field of testing tools and particularly relates to a deep hole testing tool used for testing the depth size tolerance of a part. The deep hole testing tool comprises a dial indicator, a cotter copper pin, an indicator fixing sleeve, a measuring sleeve, a return spring, a measuring core shaft, a plain end set screw, a measuring positioning pin and a measuring criteria sleeve. The deep hole testing tool is characterized in that the cotter copper pin is fixed outside the dial indicator; the plain end set screw is arranged in the indicator fixing sleeve; the measuring core shaft is embedded in the measuring positioning pin in a tight fit manner; and the return spring is arranged between the indicator fixing sleeve and the measuring core shaft. The deep hole testing tool has the benefits of high precision and abrasion resistance, can detect the depth size tolerance of a deep hole with a small diameter conveniently, accurately, quickly and visually, and solves the problem that measurement cannot be carried out with a conventional measuring tool such as a vernier caliper.
Description
Technical field
The utility model belongs to the tool field of testing, and is used to check part depth dimensions tolerance specifically.
Background technology
At present machined components often contains deep hole, and the deep hole diameter is little, the degree of depth is long, and dimension precision requirement is high, and there are problems such as bad operation, measurement data tolerance are big in the use routine when testing measurement hole depth dimensional accuracy such as tool such as vernier caliper.Therefore need design transverse axis assembly deep hole to test tool.
The utility model content
The utility model is intended to overcome the prior art defective, provides a kind of deep hole to test tool.
Deep hole is tested tool; Constitute by clock gauge, opening copper pin, table fixed cover, measuring unit, back-moving spring, measurement mandrel, flush end holding screw, measurement and positioning pin and measuring basis cover; It is characterized in that: described clock gauge and its external stability have the opening copper sheathing; Described table fixed cover is built-in with the flush end holding screw, and described opening copper pin is with the table fixed cover outward, and the table fixed cover is connected with the top of measuring unit; Described measurement mandrel locks to cooperate with measurement and positioning to be inlayed, and described back-moving spring is arranged at the table fixed cover and measures between the mandrel.
The beneficial effect of the utility model is: precision is high, wear-resisting; Can detect the depth dimensions tolerance of Small-deep Hole part convenient, accurately, quickly and intuitively, solve the problem of using conventional measurer such as vernier caliper to measure.
Description of drawings
Fig. 1 is the utility model structural representation cut-open view: wherein, and 1, clock gauge, 2, the opening copper sheathing, 3, the table fixed cover, 4, measuring unit, 5, back-moving spring, 6, measure mandrel, 7, the flush end holding screw, 8, the measurement and positioning pin, 9, the measuring basis cover.
Embodiment
Referring to accompanying drawing 1; Deep hole is tested tool; Be made up of clock gauge 1, opening copper pin 2, table fixed cover 3, measuring unit 4, back-moving spring 5, measurement mandrel 6, flush end holding screw 7, measurement and positioning pin 8 and measuring basis cover 9, it is characterized in that: described clock gauge 1 has opening copper sheathing 2 with its external stability, and described table fixed cover 3 is built-in with flush end holding screw 7; The described opening copper pin 2 outer table fixed covers 3 that are with; Described table fixed cover 3 is connected with the top of measuring unit 4, and described measurement mandrel 6 is inlayed with measurement and positioning pin 8 wringing fits, and described back-moving spring 5 is arranged at table fixed cover 3 and measures between the mandrel 6.
Described flush end holding screw 7 passes through fixedly clock gauge 1 of opening copper sheathing 2.
It is consistent with the given size of part to be measured that described measuring basis overlaps 9 height dimensions.
Described measurement and positioning pin 8, measure mandrel 6, measuring unit 4 and measuring basis cover 9, the material of use is alloy tool steel Cr12.
During application; At first will measure mandrel 6 and aim in the endoporus that pendulum inserts the measuring basis cover 9 that is placed on the flat board, secondly measuring unit 4 and measuring basis cover 9 will be compacted to no gap, take out after once more clock gauge 1 being adjusted to zero-bit; Back-moving spring 5 will be measured mandrel 6 and reset this moment; To measure mandrel 6 at last and pack into to compress in the hole in piece part to be measured and read reading shown in the clock gauge 1, the difference of this reading and clock gauge zero-bit both had been institute's gaging hole depth tolerances, took out deep hole and tested tool.
