Description

A tool steel strip dimension measuring device Technical Field

[0001] This utility model belongs to the technical field of tool steel testing equipment, and in particular relates to a tool steel strip size measuring device. Background Technology

[0002] Tool steel strip is a strip of steel made from tool steel. It features high hardness, high wear resistance, and sufficient toughness. In terms of composition, it contains a high proportion of carbon and alloying elements such as chromium, molybdenum, and tungsten. The addition of these elements gives the steel strip its excellent properties. Tool steel strip has a wide range of applications. In the field of machinery manufacturing, it can be used to make cutting tools, measuring tools, molds, etc. In automobile manufacturing, it is used for the production of some precision parts, which have high requirements for surface quality and dimensional accuracy. The dimensional measurement of tool steel strip is crucial, and its dimensions mainly cover width, thickness, and length.

[0003] Currently, the length of tool steel strips is usually measured using an encoder combined with the number of rotations of a roller. However, due to the difference in width between different sizes of tool steel strips, the strip is prone to misalignment when using a conveyor to transport the strip for length detection. Once the strip is misaligned, the rotation of the roller may deviate from the actual distance the strip moves, thus affecting the accuracy of the length measurement and causing errors in the measurement results. This makes it difficult to accurately control the length of the strip.

[0004] To address these issues, we provide a tool steel strip dimension measuring device. Summary of the Invention

[0005] The purpose of this invention is to provide a tool steel strip size measuring device. By cooperating with the correction component and the drive component, it solves the problem in the prior art that the steel strip is prone to deviation during the measurement of steel strip length, resulting in deviation in the detection data.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please refer to Figures 1-5. This utility model is a tool steel strip size measuring device, including a detection table 1. An encoder 2 is installed on the top of the detection table 1. The encoder 2 works by outputting pulse signals. When the detection roller 3 driven by the steel strip rotates, it drives the shaft of the encoder 2 to rotate, generating pulse signals. By counting these pulse signals and combining them with the resolution of the encoder 2 (the number of pulses generated per rotation) and the circumference of the roller, the distance the steel strip moves can be calculated, and thus the length of the steel strip can be calculated. The detection roller 3 is installed at one end of the encoder 2. A correction assembly is provided on one side of the detection table 1. The correction assembly includes a support frame 4 set on one side of the detection table 1, and six conveyor rollers 5 movably connected inside the support frame 4. Driven by the machine 14, the conveyor belt 6 can be rotated to transport the steel belt. The conveyor belt 6 is sleeved on the surface of the conveyor roller 5, the adjusting plate 7 is sleeved on the surface of the conveyor belt 6, and the auxiliary wheel 8 is set on one side of the adjusting plate 7. There are ten auxiliary wheels 8, which are evenly divided into two groups and installed on one side of the two groups of adjusting plates 7. The auxiliary wheels 8 are arranged horizontally. When the auxiliary wheels 8 push the steel belt to move, they can push the deviated steel belt back to its original position and maintain horizontal transport. The bottom of the support frame 4 is provided with a drive assembly, which includes a drive motor 9 installed on one side of the support frame 4 and a screw 10 installed at the output end of the drive motor 9. The screw 10 has a reverse thread design on its surface, which can drive the two sets of moving sleeves 11 to move relative to each other and in opposite directions at the same time. The moving sleeves 11 are threadedly connected to the surface of the screw 10.

[0028] Example 2

[0029] Please refer to Figures 1-5. Based on Embodiment 1, the top of the movable sleeve 11 is fixedly connected to the adjusting plate 7. The threads on both sides of the surface of the screw 10 are opposite. The surface of the auxiliary wheel 8 is movably connected to the movable seat 12. One side of the movable seat 12 is fixedly connected to the adjusting plate 7. The surface of the detection roller 3 is fitted with a vertical plate 13. The bottom of the vertical plate 13 is fixedly connected to the detection table 1. A servo motor 14 is installed on the other side of the support frame 4. The output end of the servo motor 14 is fixedly connected to the conveyor roller 5. A support block 15 is fixedly connected to the top of the conveyor belt 6. A detection roller 16 is slidably connected inside the support block 15. A push plate 17 is slidably connected to the top of the detection roller 16. A light emitter 18 is fixedly connected to the top of the push plate 17. A light receiver is installed inside the support block 15. 19. A reset spring 20 is fixedly connected to the top of the push plate 17. The light emitter 18 emits light, and the light receiver 19 receives the passing light and converts the light signal into an electrical signal. By analyzing and processing the electrical signal, the distance between the light emitter 18 and the light receiver 19 can be obtained. When the steel strip pushes the detection roller 16 upward during the conveying process, the thickness of the steel strip can be obtained using the distance data between the light emitter 18 and the light receiver 19. At the same time, the thickness of the steel strip at different positions can be detected, and the data can be corrected in time to avoid the influence of different steel strip thicknesses on the length detection data. This reduces the instability and slippage of the roller due to different steel strip thicknesses and prevents deviations in the pulse signal counting generated by the encoder 2.

[0030] The working principle of this utility model is as follows: When it is necessary to detect the length of the steel strip, the operator can start the drive motor 9. The drive motor 9, together with the conveyor roller 5, drives the conveyor belt 6 to rotate. The conveyor belt 6 conveys the steel strip. When the steel strip enters between the two sets of detection rollers 3, the friction force can be used to drive the detection rollers 3 to rotate. The detection rollers 3 drive the shaft of the encoder 2 to rotate, generating pulse signals. By counting these pulse signals, the length of the steel strip can be calculated.

[0031] While the steel belt is being conveyed, the drive motor 9 is started. The drive motor 9 drives the screw 10 to rotate. The screw 10 drives the two sets of moving sleeves 11 to move relative to each other. The moving sleeves 11, together with the adjusting plate 7, drive the auxiliary wheel 8 to move. When the auxiliary wheel 8 moves, it pushes the steel belt to move. When the two sets of auxiliary wheels 8 move relative to each other, they can push the steel belt to the center, preventing the steel belt from deviating during the conveying process and improving the accuracy of the data received by the encoder 2.

[0032] During the steel strip conveying process, the detection roller 16 can be pushed to move upward. When the detection roller 16 moves, it pushes the push plate 17 and the light emitter 18 to move. At this time, the distance between the light emitter 18 and the light receiver 19 changes. The thickness of the steel strip can be obtained by using the distance data between the light emitter 18 and the light receiver 19. At the same time, the thickness of the steel strip at different positions can be detected, and the data can be corrected in time to avoid the influence of different steel strip thicknesses on the length detection data.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
