Abstract
A measuring device of cavity type parts and a measuring method thereof relate to a measuring device of cavity type parts, in particular to measuring device which measures actual numerical values of a distance between a bottom plane of a cavity and a hole on an outer lateral surface of the cavity. The measuring device of cavity type parts comprises a positioning block, a transition plate, a dialgauge, a pin boss, guide columns and a conical pin, the upper end surface of the positioning block is connected with the pin boss through the transition plate, the positioning block is connected with the transition plate via bolts, the upper end surface of the pin boss is equipped with the dialgauge, the lower end of the pin boss is connected with the two guide columns which are arranged in parallel, and the lower end surface of the pin boss is equipped with the conical pin. The invention realizes the purpose of field control tracking and convenient and simple measurement.
Description
Technical field:
The present invention relates to a kind of measurement mechanism, especially measure the measurement mechanism of actual numerical value between the position in the hole on cavity baseplane and the lateral surface for cavity type parts.
Background technology:
The part that belongs to cavity, casing class formation form in machinery, telecommunication industry is a lot, the post hole or the taper hole that have machine work or die casting to form on the sidewall around this type of part.Baseplane in these holes and the cavity is owing to the needs of assembling have status requirement.Can not directly measure yet there is sidewall to intercept around the cavity, three-dimensional coordinates measurement can only be arranged with measurers such as slide calliper rule.But this measurement spended time is many and cost is high, can't satisfy the needs that produced on-site is measured fast.
As shown in Figure 1, between inner chamber plane A and the areole B, need control its position dimension, but because the existence of sidewall can't use general measurer directly to measure owing to assemble.And the hole on this kind die casting sidewall forms by inserting because insert and mold between the gap exist or not in place, this size often changes and causes overproofly, therefore must field control follow the tracks of.
Summary of the invention:
The object of the invention provides a kind of position that can measure fast for hole on cavity type parts intracavity bottom plane and the lateral wall, has realized the field control tracking, measures the measurement mechanism and the measuring method thereof of convenient and simple cavity type parts.
The present invention adopts following technical scheme for achieving the above object:
A kind of measurement mechanism of cavity type parts comprises locating piece, rebound, dial gauge, key seat, guide pillar, taper pin, and the upper surface of locating piece is connected with key seat by rebound, and bolt is connected between locating piece and the rebound; The upper surface of key seat is provided with dial gauge, and the key seat lower end connects two guide pillars that be arranged in parallel, and the lower surface of key seat is provided with taper pin.
Interference fit is connected between guide pillar of the present invention and the rebound.
Gap sliding connection between key seat of the present invention and the guide pillar.
Utilize the measuring method of the measurement mechanism of cavity type parts, locating piece is placed in the cavity of part to be measured, and fitted in the lower plane of locating piece and the baseplane of cavity, simultaneously upper and lower, left and right are moved key seat and taper pin are inserted in the taper hole of part sidewall to be measured, and this moment, the reading of dial gauge was exactly taper hole on the part sidewall to be measured and the deviation between the part to be measured plane.
The present invention adopts technique scheme, compared with prior art has following advantage:
1, the present invention is in fact by increasing the locating piece of known altitude, with the baseplane of the part cavity to be measured distance of translation that makes progress, so just got around the obstacle (sidewall of cavity) of centre, thereby realized the purpose of quick measurement, measures simple and convenient simultaneously.
2, the present invention is simple in structure, can measure at any time in the part assembling process, has realized on-the-spot control tracking, improves the qualification rate of product.
3, interference fit is connected between rebound of the present invention and guide pillar, the key seat, and is easy to adjust, uses simply, increased the reliability of reading in the use.

Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:
As Fig. 2, shown in Figure 3, a kind of measurement mechanism of cavity type parts comprises locating piece 1, rebound 2, dial gauge 3, key seat 4, guide pillar 5, taper pin 6, and the upper surface of locating piece 1 is connected with key seat 4 by rebound 2, and bolt is connected between locating piece 1 and the rebound 2; The upper surface of key seat 4 is provided with dial gauge 3, and key seat 4 lower ends connect two guide pillars that be arranged in parallel 5, and the lower surface of key seat 4 is provided with taper pin 6.
As Fig. 2, shown in Figure 3, interference fit is connected between guide pillar 5 and the rebound 2.
As Fig. 2, shown in Figure 3, gap sliding connection between key seat 4 and the guide pillar 5.
Utilize the measuring method of the measurement mechanism of cavity type parts of the present invention, locating piece 1 is placed in the cavity of part to be measured, and fitted in the lower plane of locating piece 1 and the baseplane of cavity, simultaneously upper and lower, left and right are moved key seat 4 taper pin 6 are inserted in the taper hole of part sidewall to be measured, and this moment, the reading of dial gauge 3 was exactly taper hole on the part sidewall to be measured and the deviation between the part to be measured plane.
As shown in Figure 1 and Figure 4, the lower plane of locating piece 1 when measuring with workpiece lumen baseplane (reference plane) applying mutually, locating piece 1 has must be highly, height is known definite value, distance that its effect has made progress translation with reference plane exactly, guide reference plane into the outside by rebound again and extend, so just walked around the obstacle (sidewall of cavity) of centre, the distance on taper hole and plane is revealed by the dial gauge that is installed on the rebound.The pin that inserts taper hole can move up and down adjusting together with key seat owing to the existence of two guide pillars 5, so that insert taper hole after aligning same position with taper hole, this moment, the position of taper pin was the position of taper hole, and the deviation of itself and standard value is pointer on the dial gauge and 0 's deviation reading.This has just reached the purpose of measuring.
