The depth measuring tool which is suitably used in factories for measuring depths of product conical bores in batches is convenient and rapid.

Description

A kind of depth measurement tools
Technical field
The utility model relates to a kind of survey instrument, especially a kind of depth measurement tools.
Background technology
At present, known cylindrical hole or conical bore depth measurement tools are pit gauges, particularly in the process of conical bore, the tapering of conical bore and the degree of depth are the important indicators whether conical bore is qualified, so in the process of conical bore, must measure the degree of depth of conical bore conical surface diverse location, to guarantee crudy, and on circular conical surface, do not have pit gauge to measure needed measuring basis plane, therefore Measurement accuracy cannot be carried out with pit gauge in conical bore or cylindrical radial hole, after measuring, need pit gauge to take out and observe from hole, both measure out of true and be also not suitable for the depth survey of typical products in mass production in factory, expend a large amount of Measuring Time, cause the waste of manpower.
Utility model content
The purpose of this utility model is existing defect in order to solve in prior art conventional depth chi and to measure, convenient and swift when a kind of measurement taper hole degree of depth is provided, save time, and the depth measurement tools that precision is high.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of depth measurement tools, comprise tabular form depth calibrator and tool body, inner side at this tool body is provided with gear train, and one end of tool body is provided with depth survey mechanism, and the two ends of described gear train are connected with depth survey mechanism with described tabular form depth calibrator respectively;
As improvement of the present utility model, described gear train comprises chuck, spring and spring base, and chuck is fixedly installed on the inner side of described tool body, and the two ends of described spring contact with spring base with described chuck respectively;
Described depth survey mechanism comprises sounding rod, axial location block and guide pin bushing radially, described axial location block and radially guide pin bushing are sleeved on the outside of described tool body, and one end of described sounding rod extend in described tool body and is fixedly connected with described spring base.
Above-mentioned a kind of depth measurement tools, described tabular form depth calibrator comprise instrument and with the instrument bar of this Instrument connection, one end of this instrument bar extend in described tool body and is connected with the spring of described gear train.
Above-mentioned a kind of depth measurement tools, the end face of the free termination of described sounding rod is plane.
Above-mentioned a kind of depth measurement tools, the end face of the free termination of described sounding rod and the end face of described radially guide pin bushing are parallel to each other.
Above-mentioned a kind of depth measurement tools, the spring of described gear train is in the raw time, and the pointer of described instrument makes zero.
The beneficial effects of the utility model are: this depth measurement tools is provided with independently instrument, gear train and depth survey mechanism, and meter reading is accurate, and precision is high, are applicable to the depth survey of typical products in mass production conical bore in factory, convenient and swift.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
Embodiment
For making architectural feature of the present utility model and the effect reached have further to understand and be familiar with in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
As shown in Figure 1, a kind of depth measurement tools, comprise tabular form depth calibrator 1 and tool body 2, in the inner side of this tool body 2, be provided with gear train 3, one end of tool body 2 is provided with depth survey mechanism 4, and the two ends of gear train 3 are connected with depth survey mechanism 4 with tabular form depth calibrator 1 respectively;
As improvement of the present utility model, gear train 3 comprises chuck 31, spring 32 and spring base 33, and chuck 31 is fixedly installed on the inner side of tool body 2, and the two ends of spring 32 contact with spring base 33 with chuck 31 respectively;
Depth survey mechanism 4 comprises sounding rod 41, axial location block 42 and guide pin bushing 43 radially, and axial location block 42 and radially guide pin bushing 43 are sleeved on the outside of tool body 2, and one end of sounding rod 41 extend in tool body 2 and is fixedly connected with spring base 33.
Tabular form depth calibrator 1 comprises instrument 11 and the instrument bar 12 being connected with this instrument 11, and one end of this instrument bar 12 extend in tool body 2 and is connected with the spring 32 of gear train.
When the depth survey of taper hole, directly sounding rod 41 is extend in taper hole and contacted with the conical surface of taper hole, when the degree of depth of conical bore conical surface diverse location is measured, the width of sounding rod end face 44 need be consistent with the aperture of this circular conical surface position, by tool body 2 is exerted pressure, spring 32 is in compressive state, and sounding rod 41 retreats, when the end face 45 of guide pin bushing 43 radially and the end contact of taper hole, the shown scale value of instrument 11 is the degree of depth of conical bore conical surface assigned address;
In the utility model, the fineness of sounding rod 41 is relevant with the pore size of conical bore to be measured, therefore no matter be that thick sounding rod or thin sounding rod all drops in protection domain of the present utility model.
As the utility model, further improve, the end face 44 of sounding rod 41 free terminations is plane, and the end face 44 of sounding rod 41 free terminations and the radially end face 45 of guide pin bushing 43 are parallel to each other, to improve its measuring accuracy.
The spring 32 of gear train 3 is in the raw time, and the pointer of instrument 11 makes zero, and reduces the error producing while measuring.
This depth measurement tools is provided with independently instrument, gear train and depth survey mechanism, and meter reading is accurate, and precision is high, is applicable to the depth survey of typical products in mass production conical bore in factory, convenient and swift.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and instructions, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
