Description

Technical Field

[0001] This utility model relates to the field of workpiece length measurement, and in particular to a device for measuring the length of long bar workpieces. Background Technology

[0002] Workpiece length measurement refers to the process of accurately measuring the length of various workpieces during machining. Accurate length measurement plays a crucial role in ensuring workpiece quality, meeting design requirements, and ensuring assembly precision.

[0003] Currently, the length measurement of long bar workpieces is mostly done using a relative measurement method. This involves using a standard length device for calibration, measuring the data at both ends with displacement sensors, then measuring the workpiece, calculating the difference between the two sensor measurements, and adding the length of the standard length device to obtain the workpiece length. However, this measurement method is cumbersome and makes it difficult to quickly measure the length of long bar workpieces, thus reducing the measurement speed. Therefore, we propose a long bar workpiece length measuring device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a length measuring device for long bar workpieces to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A length measuring device for long bar workpieces includes a marble base, a marble V-shaped seat fixedly installed on the front of the marble base, a positioning seat fixedly installed on the upper surface of the marble V-shaped seat, a displacement sensor fixedly installed on the right side of the positioning seat, a motion shaft fixedly installed on the front of the marble base, a stop block slidably connected to the upper surface of the marble V-shaped seat, and a computer located on the right side of the marble base.

[0007] In a further embodiment, the bottom end of the stop extends above the motion shaft, and the bottom surface of the stop is slidably connected to the upper surface of the motion shaft.

[0008] In a further embodiment, a protective cover is fixedly installed on the right side of the marble base, and the right side of the computer is fixedly installed to the inner wall of the marble base.

[0009] In a further embodiment, a grating ruler is fixedly installed on the front side of the marble base, and the grating ruler is located above the motion axis.

[0010] In a further embodiment, a V-shaped groove is provided on the front of the marble V-shaped seat, and the displacement sensor is located inside the V-shaped groove, with its center coinciding with the symmetry plane of the V-shaped groove.

[0011] In a further embodiment, the interior of the marble V-shaped seat is provided with a long bar workpiece, which is located to the right of the displacement sensor.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This invention uses a displacement sensor at one end and a stop at the other end. The stop is mounted above the motion shaft and works in conjunction with the position sensor to ensure that the motion shaft covers its entire length. When the stop and the displacement sensor are in contact, the measured value is zero. When a long workpiece is placed in, the stop can push the long workpiece to make it contact the displacement sensor, thus obtaining the length value. This achieves the effect of quickly measuring the length of long workpieces and improves the measurement speed. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this utility model, a long bar workpiece length measuring device includes a marble base 1, a marble V-shaped seat 3 fixedly installed on the front of the marble base 1, a positioning seat 8 fixedly installed on the upper surface of the marble V-shaped seat 3, a displacement sensor 7 fixedly installed on the right side of the positioning seat 8, a motion shaft 2 fixedly installed on the front of the marble base 1, a stop block 11 slidably connected to the upper surface of the marble V-shaped seat 3, and a computer 5 provided on the right side of the marble base 1. By placing the long bar workpiece 9 inside the marble V-shaped seat 3 during measurement, the long bar workpiece 9 can be effectively restricted during measurement. In addition, the good straightness of the marble V-shaped seat 3 can reduce the measurement error.

[0023] In a further embodiment, the bottom end of the stop 11 extends above the motion shaft 2, and the bottom surface of the stop 11 is slidably connected to the upper surface of the motion shaft 2. A protective cover 4 is fixedly installed on the right side of the marble base 1, and the right side of the computer 5 is fixedly installed to the inner wall of the marble base 1. A grating ruler 10 is fixedly installed on the front of the marble base 1. The grating ruler 10 is located above the motion shaft 2. The protective cover 4 serves to protect the computer 5. The computer 5 can display the measured length value. The grating ruler 10 on the motion shaft 2 is used to provide feedback on the coordinate position of the stop 11.

[0024] In a further embodiment, a V-groove 6 is provided on the front of the marble V-shaped seat 3, and the displacement sensor 7 is located inside the V-groove 6, with its center coinciding with the symmetrical plane of the V-groove 6. A long rod workpiece 9 is provided inside the marble V-shaped seat 3, and the long rod workpiece 9 is located to the right of the displacement sensor 7. By setting the V-groove 6, the long rod workpiece 9 can be placed more stably, which is convenient for measuring its length.

[0025] The working principle of this utility model is as follows: First, the marble base 1 is used as the foundation of all components, providing a relative plane for the installation of the marble V-shaped seat 3, which enables the marble V-shaped seat 3 to maintain straightness. The long bar workpiece 9 is placed inside the marble V-shaped seat 3 during measurement. When the long bar workpiece 9 is slowly pushed by the stop 11 on the motion shaft 2, the system monitors the reading of the displacement sensor 7 in real time. The reading remains unchanged when the long bar workpiece 9 does not contact the displacement sensor 7 or the stop 11. During the leftward movement of the stop 11, it will inevitably contact the right end of the long bar workpiece 9 first, and then push the long bar workpiece 9 to the left, which will then contact the displacement sensor 7, and then compress the displacement sensor 7, causing the reading of the displacement sensor 7 to change. The system reads the readings of the grating ruler 10 and the displacement sensor 7. A stop 11 is installed on the right side of the motion shaft 2 to push the long rod workpiece 9. The grating ruler 10 is set on the motion shaft 2 to provide feedback on the coordinate position of the stop 11. The length of the motion shaft 2 covers the entire length. First, the stop 11 is moved to the displacement sensor 7. When the stop 11 and the displacement sensor 7 are in contact, the measured value is zero. Then, the long rod workpiece 9 is placed in, and the stop 11 is used to push the long rod workpiece 9 until the long rod workpiece 9 contacts the displacement sensor 7, and the length value can be obtained.
