Technical Field

[0001] This utility model relates to the field of shaft height measuring machine technology, specifically a protection mechanism for a shaft height measuring main unit. Background Technology

[0002] In industries such as machining, automotive manufacturing, and aerospace, where strict dimensional tolerances are required for shaft components, ensuring the height accuracy of these components is crucial. Due to differences in processes and materials, even shafts produced in the same batch may exhibit dimensional errors. If these errors exceed the allowable range, the shaft may not assemble correctly with other components, affecting the performance and reliability of the final product. Therefore, measuring equipment must be used to inspect the actual height of shaft components to ensure they meet design standards and technical specifications.

[0003] Currently available shaft height measuring devices are mainly composed of precision mechanics, optical systems, and electrical components, providing high measurement accuracy. However, these devices generally lack effective protection mechanisms, leaving the main unit (including the display screen) and sensors directly exposed to the external environment when not in use. This makes the precision electronic components susceptible to dust, moisture, and other environmental factors, potentially causing measurement errors, accelerating equipment aging, reducing lifespan, and increasing maintenance costs. To address these issues, this invention proposes a protection mechanism for the shaft height measuring main unit. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Embodiment: please refer to Figures 1 to 4 According to the embodiment of the utility model, a protection mechanism of shaft height measuring host computer is provided, the protection mechanism includes base 1, end plate 3, reel 4 and protective film 5, wherein the rear side of base 1 is provided with installation cavity 2, and installation cavity 2 forms an opening on the surface of base 1;End plate 3 is semicircular, and two end plates 3 are arranged at the two ends of the upper surface of base 1, and a detection space is formed between the two end plates 3 and base 1, and a detection mechanism containing electronic components for detecting the height of shaft parts 18 is arranged in the detection space;Reel 4 is rotatably arranged in installation cavity 2;The first end of protective film 5 is fixed with reel 4, and the second end of protective film 5 extends out of the opening of installation cavity 2.

[0024] The shaft height measuring host with the above protection mechanism can effectively measure the shaft height of the shaft part 18 through the detection mechanism. When the shaft height measuring host is not in use, the protection mechanism can package the detection mechanism containing electronic components of the shaft height measuring host in the detection space for protection, so as to prevent the electronic components of the detection mechanism from being affected by external dust, humidity and other environmental factors, thereby causing measurement errors, accelerated aging of the equipment and other problems. The specific operation of the protection mechanism is as follows: after the protective film 5 is pulled out from the mounting cavity 2 to cover the opening of the detection space, the second end of the protective film 5 is fixed on the front side of the base 1 by buckling or bonding. In this way, the detection mechanism is packaged in the detection space for protection. When the detection mechanism needs to be used later, the fixation of the second end of the protective film 5 is released, and then the spool 4 is rotated to re-enter the protective film 5 into the mounting cavity 2. At this time, the opening of the detection space is opened, so that the detection mechanism in the detection space can be used to measure the shaft height of the shaft part 18.

[0025] In the example embodiment, the second end of the protective film 5 is fixedly connected with the iron fixing plate 6, and the front side of the base 1 is embeddedly and fixedly provided with the magnetic strip 7. Through the adsorption of the fixing plate 6 and the magnetic strip 7, the second end of the protective film 5 can be conveniently fixed on the front side of the base 1.

[0026] In the example embodiment, the protection mechanism further includes the sealing ring 8 arranged along the edge of the detection space. Through the arrangement of the sealing ring 8, the sealing property of the joint position between the protective film 5 and the base 1 and the end plate 3 can be improved, the airtightness of the detection space can be improved, and the entry of external dust and water vapor into the detection space can be better prevented.

[0027] In the example embodiment, one end of the spool 4 extends to the outside of the base 1 and is coaxially fixedly provided with the knob 9, and the diameter of the knob 9 is greater than the diameter of the spool 4. Through the arrangement of the knob, the force arm when driving the spool 4 to rotate is increased, so that driving the spool 4 becomes more labor-saving.

[0028] In the example embodiment, the detection mechanism comprises a slide rail 10, a support block 11, a first support base 12, a laser ranging sensor 13, a second support base 14 and a reflector 15. The slide rail 10 is fixedly arranged on the upper surface of the base 1. The two support blocks 11 are slidably connected to the slide rail 10 and used to support the shaft part 18. The first support base 12 is located on the right side of the support block 11 and fixedly connected to the base 1. The laser ranging sensor 13 is fixedly arranged on the first support base 12. The second support base 14 is located on the left side of the support block 11 and slidably connected to the slide rail 10. The reflector 15 is fixedly arranged on the second support base 14. The detection mechanism is used to detect the height of the shaft part 18. During the detection, the distance between the two support blocks 11 is adjusted according to the approximate length of the shaft part 18. Then, the shaft part 18 is placed on the two support blocks 11. Next, one end of the shaft part 18 is abutted against the first support base 12. The second support base 14 is pushed to slide along the slide rail 10 so that the second support base 14 abuts against the other end of the shaft part 18. At this time, the distance between the laser ranging sensor 13 and the reflector 15 is the shaft height of the shaft part 18. In order to facilitate the fixation of shaft parts 18 with different diameters, V-shaped limiting grooves are arranged on the top of the support blocks 11.

[0029] In order to facilitate the display of the measurement result of the laser ranging sensor 13, the detection mechanism further comprises a display panel 16 in the example embodiment. The display panel 16 is fixedly installed on the base 1 and electrically connected to the laser ranging sensor 13. When the laser ranging sensor 13 measures the shaft height of the shaft part 18, the measurement result is transmitted to the display panel 16. The user can obtain the shaft height data of the shaft part 18 through the display panel 16.

[0030] In the example embodiment, the detection mechanism further comprises an audible and visual alarm 17 which is fixedly installed on the top of the display panel 16. The audible and visual alarm 17 is electrically connected to the laser ranging sensor 13 through a plc controller. The upper limit value and the lower limit value of the plc controller are preset. When the shaft height of the shaft part 18 measured by the laser ranging sensor 13 exceeds the upper limit value or is lower than the lower limit value, the plc controller controls the audible and visual alarm 17 to issue an alarm, so as to facilitate the user to pick out the shaft part 18 which does not meet the standard.

[0031] Working principle: when measuring the shaft height of the shaft part 18, first manually adjust the distance between the two support blocks 11 according to the approximate length of the part, then place the shaft part 18 on the support blocks 11 stably and ensure that one end is in close contact with the first support seat 12. Then push the second support seat 14 to move along the slide rail 10 until it is in close contact with the other end of the shaft part 18, at this time the laser ranging sensor 13 determines the shaft height of the shaft part 18 by measuring the distance to the reflecting plate 15, and transmits the result to the display panel 16 in real time for the user to read. If the measured shaft height exceeds the preset upper limit or lower limit value, the PLC controller will automatically activate the sound and light alarm 17 to prompt the user to pay attention and pick out unqualified parts. When the shaft height measuring host is not used, the opening of the detection space can be covered by unfolding the protective film 5, and the fixed plate 6 and the magnetic strip 7 are used to form a sealed environment by being fixed on the front side of the base 1 through the adsorption effect, preventing dust and moisture from entering, and protecting the electronic components of the shaft height measuring host; when ready to use, remove the protective film 5 fixation, rotate the reel 4 to collect it into the installation cavity 2 to open the detection space, and then start a new measurement task.

[0032] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, the scope of the present application is defined by the appended claims and their equivalents.
