Description
Technical field
The present invention relates to a kind of hole two residences, are especially adapted for use in the hole measurer of backing plate spring.
Background technique
DT series of fasteners is one of common fastener system in domestic urban rail transit construction, and iron chair is the important of the fastener
Components.Support rail face is provided on iron chair to place rail, spring insertion hole to install spring.Spring is inserted into hole to holding
The height value of rail level, it is the significant dimensions of iron chair production testing that can be related to spring, which reach its ideal operation state,.At present
The size is measured usually using height gauge, but since spring insertion hole is deeper cylinder, with works such as height gauges
It is larger to have measurement error.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of hole measurers suitable for backing plate spring, overcome the prior art
In disadvantage, make to measure spring and be inserted into hole and become more accurate and conveniently to the distance in support rail face.
The present invention is achieved through the following technical solutions.
A kind of hole measurer suitable for backing plate spring, including measuring head, graduated scale, two recovery springs, sleeves, pedestal,
Above-mentioned sleeve is fixed on above-mentioned pedestal vertically, and above-mentioned graduated scale is vertically arranged and assigns into above-mentioned sleeve and can be in above-mentioned sleeve
It inside slides up and down, two above-mentioned recovery springs are vertically arranged, and top is separately fixed at above-mentioned graduated scale two sides of the bottom, bottom point
It is not fixed on the bottom of above-mentioned sleeve, for above-mentioned measuring head for cylindrical laterally setting and perpendicular to above-mentioned graduated scale, one end is solid
It is scheduled on the top of above-mentioned graduated scale.
Further, there are two above-mentioned recovery spring settings, the two sides of above-mentioned sleeve are symmetricly set on.
Further, above-mentioned measuring head is connected through a screw thread the top for being fixed on above-mentioned graduated scale.
Beneficial effects of the present invention:
The shortcomings that overcoming in the prior art makes measurement spring insertion hole become more accurate and square to the distance in support rail face
Just, with cylindrical gage measuring spring insertion hole to the distance in support rail face, measurement error is smaller, measurement it is more efficient, mention
The high quality of production and efficiency of DT series backing plate.

Specific embodiment
The present invention will be further described in detail below based on the drawings and embodiments.
- Fig. 5 referring to Fig.1, the present invention, suitable for the hole measurer of backing plate spring, including measuring head 1, graduated scale 2, recovery bullet
Spring 3, sleeve 4, pedestal 5, above-mentioned sleeve 4 are fixed on above-mentioned pedestal 5 vertically, and above-mentioned graduated scale 2 is vertically arranged and assigns
It states sleeve 4 and can be slided up and down in above-mentioned sleeve 4, two above-mentioned recovery springs 3 are vertically arranged, and top is separately fixed at
2 two sides of the bottom of graduated scale are stated, bottom is separately fixed at the bottom of above-mentioned sleeve 4, and above-mentioned measuring head 1 is cylindrical is laterally arranged simultaneously
Perpendicular to above-mentioned graduated scale 2, one end of which is fixed on the tops of above-mentioned graduated scale 2.
Further, there are two the above-mentioned settings of recovery spring 3, the two sides of above-mentioned sleeve are symmetricly set on.
Further, above-mentioned measuring head 1 is connected through a screw thread the top for being fixed on above-mentioned graduated scale 2.
When using the measurer, first backing plate spring 6 and the measurer are all placed in a plane, measuring head 1 is pushed and is inserted into
Spring is inserted into 7 the inside of hole, and measuring head of coming up 1 makes it be adjacent to the upper surface in spring insertion hole, reads the scale on scale 2,
The thickness for subtracting backing plate spring 6 is height of the spring insertion hole to support rail face.
The present invention the shortcomings that overcoming in the prior art, makes to measure spring insertion hole suitable for the hole measurer of backing plate spring
Distance to support rail face becomes more accurate and conveniently, with cylindrical gage measuring spring be inserted into hole to support rail face distance,
Measurement error is smaller, measurement it is more efficient, improve the quality of production and efficiency of DT series backing plate.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow be familiar with this field technology
Personage can understand the content of present invention and be implemented, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the scope of protection of the present invention.
