Description

Technical Field

[0001] The utility model relates to the technical field of dimension detection devices, and particularly relates to a bar dimension detection device. Background Art

[0002] Bars generally refer to simple cross-section profiles, which are straight products of metal plastic processing with a relatively large ratio of length to cross-section perimeter and no obvious convex or concave parts on the cross-section. They are also called bars or ordinary cross-section profiles, including square, round, flat, and hexagonal profiles. Before leaving the factory, it is necessary to detect whether the dimensions of the bars meet the standards, and a detection device is required to detect the bars. The existing bar dimension detection devices are mainly based on the photoelectric measurement method. During the measurement process, the probe emits parallel light, and the light is captured by the receiving unit after being reflected by the surface of the bar. By calculating the offset of the light or the change in the received light intensity, the dimensions such as the diameter and ovality of the bar can be accurately measured. However, after the bar is measured, it needs to be collected. Since the speed of bar dimension detection is relatively fast, the manual collection speed is difficult to match, which may lead to blockage of the production line and low efficiency.

[0003] In view of the above problems, the utility model proposes a bar dimension detection device. Summary of the Invention

The inner wall of the collection box is provided with a buffer filter screen, the buffer filter screen is inclined, the lowest end of the inclined surface of the buffer filter screen is provided with a bar storage box, and a debris storage box is arranged directly below the buffer filter screen.

[0013] For a bar size detection device proposed by the present utility model, after the measurement is completed, the conveying frame continuously conveys the bars to the guide plate, and the guide plate is used to guide the bars into the collection box, so that they fall on the buffer filter screen.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 5 , to solve the problem that after the bar is measured, it needs to be collected. Since the speed of bar size detection is relatively fast and the manual collection speed is difficult to match, it may cause the production line to be blocked and the efficiency to be low. The following preferred technical solutions are provided:

[0022] A bar size detection device includes a mounting bracket 1, and a conveying bracket 2 and an optoelectronic measurement main body 3 arranged at the upper end of the mounting bracket 1. One end of the conveying bracket 2 is provided with a guide plate 4. The guide plate 4 is inclined, and the lowest end of the inclined surface of the guide plate 4 is fixedly connected with a collection box 5. The inner wall of the collection box 5 is provided with a buffer filter screen 6. The buffer filter screen 6 is inclined. The lowest end of the inclined surface of the buffer filter screen 6 is provided with a bar storage box 7. The directly lower end of the buffer filter screen 6 is provided with a debris collection box 8. The buffer filter screen 6 is a component made of beryllium bronze material, which is elastic and deformable.

[0023] One side of the buffer filter screen 6 is provided with a rotating shaft assembly 9. The lower end of the buffer filter screen 6 is provided with a fixed filter screen 10. The inner wall of the collection box 5 is provided with an installation groove 11. The inner wall of the installation groove 11 is fixedly connected with an elastic rod 12. One end of the elastic rod 12 far away from the installation groove 11 is fixedly connected with the buffer filter screen 6.

[0024] The rotating shaft assembly 9 includes an inner shaft main body 91 fixedly connected to one end of the fixed filter screen 10, and an outer shaft main body 92 rotatably connected to one end of the fixed filter screen 10. The outer shaft main body 92 is rotatably connected to the outer wall of the inner shaft main body 91. A return torsion spring 93 is sleeved on the outer wall of the inner shaft main body 91. One end of the return torsion spring 93 is fixedly connected with a middle connection block 94. One end of the middle connection block 94 far away from the return torsion spring 93 is fixedly connected with the buffer filter screen 6. The buffer filter screen 6 is fixedly connected to the inner wall of the outer shaft main body 92.

[0025] Specifically, when measuring the size of a bar, the bar is placed on the conveying rack 2, and the conveying rack 2 is used to convey the bar to the photoelectric measurement main body 3. The photoelectric measurement main body 3 emits parallel light, and the light is captured by the receiving unit after being reflected by the surface of the bar. By calculating the offset of the light or the change in the received light intensity, the size of the bar is measured. After the measurement is completed, the conveying rack 2 continuously conveys the bar to the guiding plate 4, and the guiding plate 4 is used to guide the bar into the collection box 5, so that it falls on the buffer filter screen 6. Due to the elasticity of the beryllium bronze material, the bar will bounce slightly, causing the debris on the bar to fall into the debris collection box 8, and the bar rolls onto the bar storage box 7 through the buffer filter screen 6, which is convenient for collection and solves the problem that after measuring the bar, collection is required. Since the speed of bar size detection is relatively fast, it is difficult for manual collection speed to match, which may lead to production line blockage and low efficiency.

[0026] When the bar falls on the buffer filter screen 6, it will press down the buffer filter screen 6 by its own gravity, driving the buffer filter screen 6 to press down the elastic rod 12, and the outer shaft main body 92 will also rotate at an angle, thus compressing the reset torsion spring 93. Through the reaction force of the reset torsion spring 93 and the elastic rod 12, the buffer filter screen 6 will vibrate at a high frequency, thereby improving the efficiency of collecting debris.

[0027] In summary: The photoelectric measurement main body 3 emits parallel light, and the light is captured by the receiving unit after being reflected by the surface of the bar. By calculating the offset of the light or the change in the received light intensity, the size of the bar is measured. After the measurement is completed, the conveying rack 2 continuously conveys the bar to the guiding plate 4, and the guiding plate 4 is used to guide the bar into the collection box 5, so that it falls on the buffer filter screen 6. It will press down the buffer filter screen 6 by its own gravity, driving the buffer filter screen 6 to press down the elastic rod 12, and the outer shaft main body 92 will also rotate at an angle, thus compressing the reset torsion spring 93. Through the reaction force of the reset torsion spring 93 and the elastic rod 12, the buffer filter screen 6 will vibrate at a high frequency, causing the debris on the bar to fall into the debris collection box 8, and the bar rolls onto the bar storage box 7 through the buffer filter screen 6, which is convenient for collection.
