High-precision inner conical surface taper rapid detection tool
Technical Field
The invention relates to a high-precision rapid detection tool for taper of an inner conical surface.
Background
The pipeline system is connected with each other by adopting a connection scheme of a filler neck and a ball head, and the detection modes of the filler neck on the taper size of the inner conical surface are two: one is to make a special angle gauge, carry out light transmission detection and judge whether the product is qualified or not according to the light transmission; the other is detection using a three coordinate measuring machine. These two measurement methods mainly have the following problems:
1. the detection precision is low: the special gauge is used for measuring whether the product is qualified or not according to the transmittance, and when the taper precision is high, the transmittance difference of the gauge is not obvious, so that the product cannot be judged to be qualified or not by human eyes.
2. The detection efficiency is low: using a three-coordinate measuring machine to carry out detection, and if the measurement is unqualified, adjusting parameters and then sending to be detected until the measurement is qualified; the subsequent production and processing are still required to be inspected when a certain quantity is reached due to the influence of the abrasion of the cutter; in the frequent inspection process, operators and equipment are in a stop waiting state, which greatly wastes manpower and equipment resources, and particularly, if unqualified products are found in the spot check process, the production is stopped and the check is carried out or all parts in the spot check section are inspected, which seriously affects the production efficiency.
Disclosure of Invention

The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a conical surface tapering short-term test frock in high accuracy, includes percentage table, spring, detection arm, support and support bolt, wherein: the support comprises a support body, and a detection arm mounting cushion block and a dial indicator mounting block which are arranged on the support body, wherein the support body is L-shaped, the detection arm mounting cushion block and the dial indicator mounting block are respectively arranged at the lower part and the upper part of the same side of the support body, bolt holes are formed in the detection arm mounting cushion block, and through holes are formed in the dial indicator mounting block and used for mounting a dial indicator; the detection arm comprises a detection rod and a push rod which are equal in length and 90 degrees from each other, a probe is arranged at the free end of the detection rod, and the free end of the push rod is a probe contact end and is used for being in contact with a probe of the dial indicator; the support bolt is sleeved with a spring and penetrates through a bolt hole in the detection arm mounting cushion block to fix the detection arm on the support.
Compared with the prior art, the invention has the following positive effects:
1) the operability is strong: the tool is simple to operate, data display is visual, and no skill requirement is imposed on an operator.
2) The production efficiency is improved: according to the detection scheme, whether the product is qualified or not is judged by a metering detection center in the existing detection scheme, and the product machine and an operator perform detection and judgment by themselves, so that intermediate links of inspection waiting are reduced, the production rhythm is continuously carried out, and the production efficiency is greatly improved.
3) The quality stability is high: in the aspect of quality control, due to the fact that the easy operability of the scheme is improved, the spot check of the existing scheme can be changed into the mode that an operator detects parts before each part is taken off, unqualified products can be found in time, and the way of leakage detection and discharge of the unqualified products is avoided.

Detailed Description
The invention relates to a tool for rapidly detecting high-precision conical taper, which mainly comprises components of a dial indicator 1, a spring 2, a detection arm 3, a support 4 and a support bolt 5, wherein the components comprise:
the structure of the detection arm 3 is shown in fig. 2, and includes: detection pole 31, push rod 32, bolt hole 33, probe 34 and gauge head contact end 35, wherein: the length of the detection rod 31 is equal to that of the push rod 32, the detection rod 31 and the push rod 32 are 90 degrees, the detection rod 31 is an oblong rod, a probe 34 is arranged at the free end of the detection rod 31, and the diameter of the probe 34 is larger than that of the detection rod; the section of the push rod 32 is square, the free end of the push rod 32 is a measuring head contact end 35 which is used for being in contact with a measuring head of a dial indicator, and in order to keep the contact between the free end of the push rod and the measuring head more stable, the contact surface between the measuring head contact end 35 and the measuring head is designed to be an arc-shaped groove. The support bolt 5 passes through the bolt hole 33 to fix the detection arm 3 on the support 4. When the detection arm 3 works, the axis of the support bolt 5 is used as a rotation center line, and the detection arm rotates downwards under the action of the spring 2.
The structure of the support 4 is shown in fig. 3 and comprises: support body 41, spacing post 42, detection arm installation cushion 43 and percentage table installation piece 44, wherein: the support body 41 is L-shaped, the detection arm mounting cushion block 43 and the dial indicator mounting block 44 are respectively mounted on the lower portion and the upper portion of the same side of the support body 41, the bolt hole is formed in the detection arm mounting cushion block 43, the limiting column 42 is arranged on the upper left of the bolt hole, and the dial indicator mounting block 44 is provided with a through hole for mounting a dial indicator. The support 4 is the main part that detects the frock, and each spare part that detects the frock all installs on the support.
The structure of the support bolt 5 is shown in fig. 4, and comprises a thread section 21 at the foremost end, a detection arm mounting cushion block passing section 22, a spring supporting section 23 and a nut 24, and the main function is to cooperate with the spring 2, fix the detection arm 3 on the support 4 and ensure that the detection rod 31 rotates by taking the axis of the support bolt 5 as a rotation center line.
Installing the support 4 of the detection tool 53 on the tool rest 54 in the same way as installing the cutter body of the cutter, wherein the height requirement of the support is that the central line of a bolt is parallel to the central line of the chuck 51, as shown in fig. 5; the detection arm 3 is arranged on the support 4 through a support bolt 5 and a spring 2, and the support bolt 5 is adjusted to enable the detection arm 3 to rotate freely; the dial indicator 1 is mounted on the support 4 with its gauge head in contact with the gauge head contact end 35 of the detection arm 3. When the support 4 moves linearly in the Z-axis direction (i.e., the horizontal moving direction shown in fig. 5), the detecting arm makes the detecting arm probe 34 always keep engaging with the detected surface of the part 52 (as shown in fig. 6) under the action of the spring. And in the rotation process of the detection arm, calculating according to a formula to obtain a taper tolerance value, and observing whether the reading fluctuation generated by the dial indicator is within a calculated result range, wherein the reading is qualified within the range, and the reading is unqualified if the reading fluctuation exceeds the range.
Example calculation formula: as shown in fig. 7, the part taper is 24 °, taper length is 20mm, orifice diameter D is 15mm, orifice major diameter D is calculated to be 23.5mm, taper radius difference (as the tooling detects a radius value) = (D-D) ÷ 2= (23.5-15) ÷ 2=4.25 mm;
the 24-degree taper tolerance is +/-5', the upper deviation is 24.09 degrees, the lower deviation is 23.91 degrees, the deviation of the upper deviation value and the lower deviation value in the range of 20mm in length is +/-0.03 mm, the radius value is +/-0.015 mm, and the difference value is the difference value between the upper deviation value and the lower deviation value; the dial indicator in the state of fig. 6 (a) reads 0, and when the Z-axis moves straight to the state of fig. 6 (b), the difference range shown by the dial indicator is between 4.25 ± 0.015 (i.e. 4.235-4.265), which is passed.
