Description

Detection tool for inner hole of valve block

Technical Field

The utility model relates to a technical field of utensil is examined to the valve block, more specifically says, it relates to a detection instrument for valve block hole.

Background

The valve block is used for an electro-hydraulic servo control system, and the failure of the valve block mainly shows that the fit clearance between the hole and the rod is overlarge. In the prior art, the hole is detected by adopting a precise device and instrument, and the manufacturing cost is extremely high.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a detection instrument for valve block hole that rational in infrastructure is simple, and the practicality is strong, detects with low costs.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a detection instrument for valve block hole, includes the support and can dismantle the measurement member of connection with the support, the support include the handle and with the fixed elastic structure of the arbitrary one end of handle, the elastic structure is including having open-ended U type fixture block and being used for adjusting the elasticity bolt of U type fixture block open size, U type fixture block has elasticity, elasticity bolt and U type fixture block threaded connection, the one end that the elasticity bolt is close to the handle outside is equipped with the knob, offer the movable hole that is used for measuring the member and runs through on the U type fixture block, the tip of measuring the member have with the measurement disc of valve block hole adaptation.

Through adopting above-mentioned technical scheme, measure the diameter that the measuring disc on the member is the pole with the valve block, surveyor will measure the member through handheld handle and insert the downthehole that will detect, observe the clearance between measuring disc and the downthehole wall. And (4) carrying out contrast detection by replacing customized measuring rod pieces corresponding to the sizes of different holes. The U-shaped clamping block is adjusted in opening size through the elastic bolts, and then the measuring rod piece is disassembled and assembled.

The utility model discloses further set up to: the handle is characterized in that an elastic U-shaped connecting block is arranged at the connecting end of the handle and the elastic structure, a positioning through hole is formed in the U-shaped connecting block, a guide pillar capable of being inserted into the positioning hole is arranged at the end of the handle, and the elastic bolt penetrates through the U-shaped connecting block and the U-shaped clamping block and is in threaded connection with the U-shaped connecting block and the U-shaped clamping block.

Through adopting above-mentioned technical scheme, to the different hole circumstances, set up rotatable angle with the handle for convenient measurement, realize through the guide pillar on U type connecting block and the handle, also through same elasticity bolt to handle control elasticity.

Detailed Description

The first embodiment of the present invention is further explained with reference to fig. 1 to 2.

The embodiment has the specific structure that: including the support and can dismantle measurement member 2 of being connected with the support, the support includes handle 1 and the fixed elastic structure of 1 arbitrary one end of handle, and the elastic structure is including having open-ended U type fixture block 3 and being used for adjusting the elasticity bolt 4 of 3 opening sizes of U type fixture block, and U type fixture block 3 has elasticity, and

elasticity bolt

4 and 3 threaded connection of U type fixture block, the one end that elasticity bolt 4 is close to the 1 outside of handle is equipped with knob 41, offer on U type fixture block 3 and be used for measuring movable hole 301 that member 2 runs through, the tip of measuring member 2 has the measurement disc 21 with valve block hole adaptation. The U-shaped fixture block 3 is further provided with a through hole 302 for improving the elasticity of the U-shaped fixture block.

The measuring disc 21 on the measuring rod 2 is the diameter of the rod of the valve block, and a measurer inserts the measuring rod 2 into the hole to be detected by holding the handle 1 with hand, and observes the gap between the measuring disc 21 and the inner wall of the hole. The comparison detection is carried out by replacing the customized measuring rod 2 corresponding to the sizes of different holes. The size of the opening of the U-shaped clamping block 3 is adjusted through the elastic bolt 4, and then the measuring rod piece 2 is disassembled and assembled.

Be equipped with on the link of handle 1 and elastic structure and have elastic U type connecting block 5, have positioning hole on the U type connecting block 5, the end of handle 1 is equipped with the guide pillar 11 that can insert the locating hole, elasticity bolt 4 runs through U type connecting block 5 and U type fixture block 3 and with both threaded connection.

Aiming at different hole conditions, the handle 1 is provided with a rotatable angle for convenient measurement, the U-shaped connecting block 5 and the guide pillar on the handle 1 are used, and the tightness of the handle 1 is controlled by the same elastic bolt 4.

Example two, as shown in fig. 3: in order to meet the detection of the depth of the hole, the measuring rod 6 can be arranged in a telescopic shape, and the structure can be as follows: the measuring device comprises a measuring rod 6, a cylinder 5 penetrates through the measuring rod along the length direction of the cylinder 5, a measuring disc 61 is arranged at the end part of the measuring rod 6, one end of the measuring rod 6 extends out of the cylinder 5, a push disc 62 is arranged at the end of the measuring rod 6, a scale mark 6a is arranged on the measuring rod 6, a reference part 51 is arranged at the end part of the cylinder 5, and the reference part can be a disc. When measuring the depth, push the benchmark portion outside the hole, push away the pushing disc 62 through the finger and push measuring rod 6 into the hole until measuring disc 61 and hole bottom conflict, obtain deep distance through observing the scale mark.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
