Description

A Multi-step Dimensions Measuring Tool for One Time Measurement

technical field

The invention belongs to detection technology, and relates to a device for quickly measuring the dimensions of multiple steps of machined parts.

Background technique

In mechanical processing, it is often necessary to detect the multi-step size of parts. Usually, the height ruler is used to measure multiple times, and the data is read on the engraved line each time. This measurement method has large visual errors, poor detection accuracy, and low detection efficiency. It is not suitable for the fast and economical requirements of batch production.

Contents of the invention

The purpose of the present invention is to design and manufacture a measuring fixture for three-step dimensions in machined parts, so as to improve the measurement accuracy and improve the measurement efficiency.

The technical solution of the present invention is: a multi-step dimension one-time measurement inspection tool, which is characterized in that it includes a base 1, a guide post 2, a spring 3, a guide sleeve 4, a rib plate 5, a frame 6, a dial indicator 7, Fastening screw 8, limit rod 9, screw 10, pile code 11; Base 1 is a cuboid, and guide post 2 is installed in the middle of its rear part, and guide post 2 is locked with screw 10, and guide post 2 is axially aligned with the base. The horizontal plane of the seat 1 is vertical, and the guide post 2 is sequentially set with a spring 3, a guide sleeve 4, and a pile code 11 from top to bottom; There are three upper and lower through holes in the front of the frame 6, and the three dial gauges 7 are respectively fixed in these three holes on the frame 6 and locked by fastening screws 8; the measuring head of the dial gauge 7 is always Align the surface to be measured of the detected part 12; the limit rod 9 is threaded into the corresponding hole under the frame 6 through its head.

The guide sleeve 4 is precisely slidingly matched with the guide post 2 , and the axial concave R of the guide sleeve 4 is matched with the convex R on the guide post 2 .

The axis lines of the three upper and lower through holes at the front of the frame 6 are perpendicular to the horizontal plane of the base 1 .

The pile code 11 is sleeved on the guide post 2 , and its lower end surface is in contact with the upper end surface of the guide sleeve 4 .

The advantages of the present invention are:

Provides a multi-step size one-time measurement inspection tool, which can effectively improve the measurement accuracy, improve the measurement efficiency, and meet the online, fast and economical requirements of batch production.

detailed description

The present invention will be described in further detail below.

Please refer to Figure 1, Figure 2, Figure 3, and Figure 4 at the same time.

The detection tooling of the present invention includes a base 1, a guide post 2, a spring 3, a guide sleeve 4, a rib 5, a frame 6, a dial indicator 7, a fastening screw 8, a limit rod 9, a screw 10, and a pile code 11.

When the present invention is in use, first three dial indicators 7 are fastened in three through holes of the frame 6 with screws 8, and the stop bar 9 is screwed into the threaded hole of the frame 6, and the dial indicator is set on the basis of the standard block gauge. The sub-meter 7 is pre-compressed half a circle and adjusted to zero position. At this time, the limit rod 9 is also in contact with a step surface of the size to be measured, and the size of the standard block gauge is consistent with the nominal size between the three surfaces to be measured.

The spring 3 of the present invention is set on the guide post 2 and under the lower end surface of the guide sleeve 4, the guide sleeve 4 is connected with the frame 6 through the rib plate 5 and fixed as one, and the measured part 12 is placed on the horizontal plane of the base 1 The front part, the bottom of the frame 6, three step surfaces to be measured are under the probes of the three dial gauges 7.

When the present invention is used for detection, the pile code 11 is set on the guide column 2, and under the gravity of the pile code, the guide sleeve 4 moves down and the compression spring 3 shrinks. The stylus of the block dial indicator 7 changes from the lower limit state to rising, and the pointer indicates the actual deviation value of the dimension between the 12 steps of the measured part. Pick up the pile code 11 and separate it from the guide post 2. Under the elastic force of the spring 3, the guide sleeve 4 moves up, synchronously drives the rib plate 5 and the frame 6 to rise, and the measuring head of the dial gauge 7 is separated from the step surface to be tested. An action of detecting the dimensions between the three steps is completed.
