Description
Technical field
The utility model belongs to checkout equipment Instrument technology field, particularly a kind of measurement mechanism of part wall thickness.
background technology
At present, device for part wall thickness measuring is many, as vernier caliper, height gauge and supersonic thickness meter etc., these instruments precision when measuring common parts generally can reach 0.01mm left and right, but in the industries such as casting, due to the complex structure of some foundry goods and cured film part and mostly be irregularly shaped, in it is carried out to wall thickness measuring process, error is larger, the support plate wall thickness of wax-pattern product as large-scale in certain and cast product is because of the singularity of its integral piece structure, wax-pattern product is to adopt its compacting tool set die cavity to confirm that whether wall thickness value is qualified, foundry goods is after measuring with supersonic thickness meter, by reviewer, estimated the general one-tenth-value thickness 1/10 of its wall thickness, confirm that whether it is qualified, this metering system error is larger, generally exceed ± 0.1mm.
utility model content
The problem existing for solving prior art, the utility model provides a kind of part Wall Thickness Testing Device, improved the measuring accuracy of the thickness of complicated irregular die cavity part, and measuring process is simple, and applied range.
The technical solution of the utility model is as described below:
A kind of part Wall Thickness Testing Device, by base, main scale, formed, main scale is arranged on base, it is characterized in that being provided with on described main scale lower secondary chi and on secondary chi, upper secondary chi is arranged on lower secondary chi top, lower secondary chi is provided with support bar A, the other end of support bar A is provided with straight shape gauge head, and upper secondary chi is provided with support bar B, and support bar B is provided with reading device, connection activity gauge head on reading device, straight shape gauge head is spatially corresponding with X-axis and Y direction with movable gauge head.
Advantage of the present utility model and beneficial effect are:
Use this device, the touched place thickness of the irregular foundry goods of complexity and cured film part is measured accurately, degree of accuracy can reach 0.01 ㎜, and easy to operate, this device also can be applicable to the complexity beyond casting industry, the measurement of irregular part thickness, and measuring accuracy is high, and simple to operate.

embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but the scope that should at this point not be interpreted as theme described in the utility model only limits to following embodiment, do not departing from the above-mentioned technological thought situation of the utility model, all various modifications, replacement and changes of making according to ordinary skill knowledge and customary means, include in scope of the present utility model.
As shown in Figure 1, a kind of part Wall Thickness Testing Device, by base 1, main scale 2, formed, main scale 2 is arranged on base 1, it is characterized in that being provided with on described main scale 2 lower secondary chi 3 and on secondary chi 4, upper secondary chi 4 is arranged on lower secondary chi 3 tops, lower secondary chi 3 is provided with support bar A302, the other end of support bar A302 is provided with straight shape gauge head 301, upper secondary chi 4 is provided with support bar B401, support bar B401 is provided with reading device 402, connection activity gauge head 403 on reading device 402, and straight shape gauge head 301 is spatially corresponding with X-axis and Y direction with movable gauge head 403.
Further, in the present embodiment, described reading device 402 is percentage tabular form wall thickness device, between movable measuring staff 403 and percentage tabular form wall thickness device for lever is connected,
Further, in the present embodiment, between described support bar A302 and lower secondary chi 3, and between support bar B401 and upper secondary chi 4 for being flexibly connected, for regulating the length of support bar A302, support bar B401, so as to adapt to different part needs.
The utility model measuring process is:
1. use first by straight shape gauge head 301 contact part inwalls;
2. movable gauge head is adjusted to straight shape gauge head 301 equal-height positions, promotion activity gauge head 403 contact part outer walls, determine now measured wall thickness value by the reading of reading device.
Its degree of accuracy of the testing result of this device can reach 0.01 ㎜, than present supersonic thickness meter accuracy class used, has improved 10 times.
