Abstract
The utility model relates to an utensil is examined in groove special use of piston jump ring, including the main scale, the main scale activity is provided with vice chi, vice chi upper end is provided with the pilot pin, the lower extreme is provided with and removes the wheel, main scale left side lower extreme is provided with left external diameter and surveys the foot, left side external diameter is surveyed the foot left side and is provided with rather than vertically left side internal diameter survey foot, vice chi lower extreme mirror image respectively is provided with and surveys the right internal diameter survey foot that right external diameter that the foot corresponds was surveyed the foot, was corresponded with left internal diameter survey foot with left external diameter. The utility model discloses simple structure, convenient operation, application scope is wide, and it is high that the numerical precision is detected in the jump ring groove, effectively the quality of control piston ring product.
Description
Technical field
This utility model relates to non-standard equipment cubing, is specifically related to a kind of piston circlip groove appliance special for detecting.
Background technology
In the production of piston, diameter to two jump-ring slots, groove width and two separation have strict demand, in production application, diameter is measured the slide gauge using survey foot with holes, measurement to groove width is all to use groove width feeler gauge, separation is measured and uses special calliper, although this metering system can guarantee that precision, but there is the problem that measurer kind is many, particularly groove width and the measurement of spacing, use feeler gauge and calliper, belong to and compare measurement, while being difficult to accurate reading, also need to make special gauge for different product specifications, not only increase cost but also increase the managerial workload of measurer.Detect project for piston circlip groove, design a set of comprehensive slide gauge, it is achieved it is necessary for directly measuring.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple in construction, easy to operate, measured value accurate piston circlip groove appliance special for detecting.
For solving above-mentioned technical problem, this piston circlip groove appliance special for detecting, including main scale, described main scale is movably set with secondary chi, chi upper end is provided with pilot pin to described pair, lower end is provided with movable pulley, described main scale lower-left end is provided with left outside footpath and surveys foot, and described left outside footpath is surveyed and is provided with perpendicular left inside footpath survey foot on the left of foot；Described secondary chi lower end mirror image respectively is provided with the rightinternal diameter surveying right external diameter survey foot corresponding to foot with left outside footpath corresponding with left inside footpath survey foot and surveys foot.First left and right internal diameter survey foot is vertically arranged in footpath Kong Chu when this utility model measures jump-ring slot diameter, and adjusted by movable pulley and to survey foot to left and right internal diameter and contact the both sides inner diameter wall of jump-ring slot respectively, surveyed reading adds left and right internal diameter survey foot gauge i.e. aperture actual size.When measuring jump ring separation, utilize left and right external diameter to survey foot and measure and can carry out separation reading to direct convenience.When measuring groove width, owing to two jump-ring slots are to use same tool sharpening, groove width is consistent；During measurement, first surveying foot with left and right external diameter and measure the inner side spacing of two grooves, reading is L1, then secondary chi is promoted to measure the distance outside two grooves, reading is L2, after L2 is deducted L1 plus left and right external diameter survey foot thickness be two well widths and, then be the width of single cavity divided by institute's value after 2.
Further, the thickness sum that described left outside footpath survey foot and right external diameter survey foot is set to 2mm；Described left inside footpath is surveyed the thickness sum of foot and rightinternal diameter survey foot and is set to 6mm.Through enterprise, a large amount of production practices prove, it is convenient for measuring the reading of numerical value, and applied widely.
This utility model simple in construction, easy to operate, applied widely, jump-ring slot detection numerical precision is high, can effectively control the quality of piston ring product.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model static condition；
Fig. 2 is detection object of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described:
As shown in Figure 1 and Figure 2, a kind of piston circlip groove appliance special for detecting, including main scale 1, described main scale 1 is movably set with secondary chi 2, chi 2 upper end is provided with pilot pin 3 to described pair, lower end is provided with movable pulley 4, described main scale 1 lower-left end is provided with left outside footpath and surveys foot 6, and described left outside footpath is surveyed and is provided with perpendicular left inside footpath survey foot 5 on the left of foot 6；Described secondary chi 2 lower end mirror image respectively is provided with the rightinternal diameter surveying right external diameter survey foot 6 ' corresponding to foot 6 with left outside footpath corresponding with left inside footpath survey foot 5 and surveys foot 5 '.
Described left outside footpath is surveyed the thickness sum of foot 6 and right external diameter survey foot 6 ' and is set to 2mm；Described left inside footpath is surveyed the thickness sum of foot 5 and rightinternal diameter survey foot 5 ' and is set to 6mm.
Randomly draw processing back piston 7 to be checked；
1, during measurement jump-ring slot internal diameter, using left inside footpath to survey foot 5 and rightinternal diameter is surveyed foot 5 ' and measured, the reading surveyed adds that size 6mm of two internal diameters survey feet is the actual size in aperture.
When 2, measuring jump ring separation, directly utilize left outside footpath survey foot 6, right external diameter is surveyed foot 6 ' and is measured two separation, can carry out separation reading to direct convenience.
When 3, measuring groove width, owing to two grooves are to use same tool sharpening, groove width is consistent.During measurement, first survey foot 6 ' measure spacing inside two jump-ring slots with left outside footpath survey foot 6, right external diameter, reading is L1, then secondary chi 2 is promoted to measure the outer lateral extent of two jump-ring slots, reading is L2, after L2 is deducted L1 plus two external diameters survey foot thickness 2mm be two jump-ring slot width and, be the width of single cavity, i.e. groove width B=(L2-L1+2 divided by institute's value after 2)/2.
This utility model simple in construction, easy and simple to handle, readings is accurate, quickly can judge piston ring product quality, improve work efficiency in production.
