Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, and more specifically, to a measuring instrument for the tilt angle of an inclined hole. Background Technology

[0002] With the development of society, many parts have complex structures. For example, inclined holes need to be set on the surface of the lens barrel for assembly or other purposes. However, some holes have high requirements and need to have specific inclination angles. Conventional measuring tools cannot meet the inspection requirements, and special inspection devices are needed to inspect their angles.

[0003] In existing technologies, the oblique holes in the microscope tube need to be measured to verify whether they meet the standards. Currently, this is generally done by measuring the diameter and height of the microscope tube with an electronic digital dial indicator, and then calculating the length of the oblique hole using the Pythagorean theorem. However, existing electronic digital dial indicators are usually bolted on. When measuring oblique holes in microscope tubes of different widths, the electronic digital dial indicator needs to be constantly adjusted in height to facilitate the measurement. As mentioned above, the electronic digital dial indicator needs to be constantly disassembled and installed by the operator using bolts, which can easily lead to insecure installation and ultimately inaccurate measurements. Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a measuring instrument for the tilt angle of inclined holes.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tilt angle measuring instrument for inclined holes, including a support platform, an inclined column, and an electronic digital display dial indicator. The surface of the support platform is provided with two sets of first and second sliding grooves, and the second sliding groove is located between the two sets of first sliding grooves. The electronic digital display dial indicator is slidably mounted on the first and second sliding grooves. The outer ring surface of the electronic digital display dial indicator is provided with multiple sets of raised blocks. The bottom of the electronic digital display dial indicator is slidably connected to a measuring column, and the measuring column sliding at the bottom of the electronic digital display dial indicator faces the inclined column.

[0006] By adopting the above technical solution, the electronic digital micrometer is slidably set with the first and second slides to facilitate the vertical adjustment of the electronic digital micrometer. The position of the electronic digital micrometer can be changed according to the size of the microscope tube, eliminating the need for bolt installation and disassembly, reducing the loosening phenomenon during the installation of the electronic digital micrometer, and thus improving the accuracy of subsequent measurements by the electronic digital micrometer.

[0007] The present invention is further configured such that: the inclined column is fixedly connected to one side of the support platform, the side of the support platform is provided with a graduated scale, the inner side of the first slide groove is provided with multiple sets of snap-fit ​​holes, and the electronic digital display dial indicator is detachably connected in the first slide groove.

[0008] By adopting the above technical solution, the setting of the graduated scale is for measuring the value of the microscope tube and also to provide the staff with the value to further determine the length of the microscope tube.

[0009] The present invention is further configured such that: a fixing block is fixedly connected to both sides of the back of the electronic digital display dial indicator; a sliding block is slidably connected to both sides of one of the fixing blocks; a spring is fixedly connected inside the fixing block; a fixing plate is fixedly connected to the side of the spring; the end of the fixing plate away from the spring is fixedly connected to the sliding block; multiple sets of snap-fit ​​holes are opened on both sides of the sliding block and the first slide groove to adapt to each other; two sets of sliding blocks and fixing plates are arranged in the fixing block; the ends of the two sets of sliding blocks are T-shaped.

[0010] By adopting the above technical solution, the sliding block and spring are used so that the electronic digital dial indicator can be engaged with the locking holes at different positions when adjusting the vertical distance, which facilitates the fixing of the electronic digital dial indicator.

[0011] The present invention is further configured such that: a tension spring is fixedly connected to the middle of the back of the electronic digital micrometer, and a sliding plate is fixedly connected to the end of the tension spring away from the electronic digital micrometer; the sliding plate is slidably connected in the second slide groove; the tension spring fixedly connected to the middle of the electronic digital micrometer is arranged in three sets; the three sets of tension springs are evenly distributed and fixed on the surface of the sliding plate; and the sliding plate and the second slide groove are snap-fitted together.

[0012] By adopting the above technical solution, the sliding plate and tension spring not only enable the electronic digital display dial indicator to be adjusted up and down, but also allow the electronic digital display dial indicator to remain on the track of the first and second slides without completely detaching from the support platform during the adjustment process. This makes it easier to fix the adjusted electronic digital display dial indicator in the first and second slides.

[0013] In summary, this utility model has the following beneficial effects: by setting up the first slide groove, the second slide groove, the fixing block, the sliding block, the sliding plate, and the tension spring, the operator can pull the electronic digital display dial indicator to disengage the fixing block and the sliding block from the first slide groove and the snap-fit ​​hole, and adjust the electronic digital display dial indicator up and down. This makes it easy to change the distance of the electronic digital display dial indicator according to the size of the microscope tube, and eliminates the need for the operator to disassemble and install it with bolts, thereby improving the strength of the installation and the accuracy of subsequent measurements.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Please refer to the embodiments of this utility model. Figures 1 to 4 The inclined hole tilt angle measuring instrument includes a support platform 1, an inclined column 2, and an electronic digital display dial indicator 7. The support platform 1 has two sets of first sliding grooves 4 and second sliding grooves 5 on its surface. The second sliding groove 5 is located between the two sets of first sliding grooves 4. The electronic digital display dial indicator 7 is slidably mounted on the first sliding grooves 4 and second sliding grooves 5. The measuring column 9 at the bottom of the electronic digital display dial indicator 7 slides towards the inclined column 2. In this embodiment, the cooperation of the electronic digital display dial indicator 7, the measuring column 9, and the inclined column 2 enables the measurement of the inclined hole of the microscope tube. When the inclined hole of the microscope tube is inserted into the inclined column... At time 2, the outer ring surface of the microscope tube will slide against the measuring column 9 in the electronic digital micrometer 7. During the sliding process, the specific value will be displayed on the screen of the electronic digital micrometer 7. For example, if the measured length of the oblique hole of the microscope tube is 13cm and the width of the microscope tube is 5cm, according to the Pythagorean theorem formula a² + b² = c² (where a represents the width of the microscope tube, b represents the length of the microscope tube, and c represents the length of the oblique hole of the microscope tube), the length of the microscope tube in this embodiment is 12cm. If this standard is a qualified size, the measurement of the microscope tube is complete.

[0021] The following structure facilitates the measurement of the microscope tube; please refer to it. Figures 1 to 3The inclined column 2 is fixedly connected to one side of the support platform 1. The side of the support platform 1 is provided with a scale 3. Multiple sets of snap-fit ​​holes 6 are opened on the inner side of the first slide groove 4. The electronic digital display dial indicator 7 is detachably connected in the first slide groove 4. Multiple sets of raised blocks 8 are provided on the outer ring surface of the electronic digital display dial indicator 7. The bottom of the electronic digital display dial indicator 7 is slidably connected with a measuring column 9. In this embodiment, the scale 3 and raised blocks 8 are provided for the purpose of allowing the operator to further determine the length of the lens tube through the scale 3. On the other hand, the raised blocks 8 will increase the friction between the operator and the operator when the operator holds the electronic digital display dial indicator 7.

[0022] The following details the structure of the connection between the electronic digital dial indicator 7 and the first slide 4. Please refer to the following: Figures 1 to 4 The electronic digital micrometer 7 has fixed blocks 10 on both sides of its back. Sliding blocks 11 are slidably connected to both sides of one of the fixed blocks 10. A spring 102 is fixedly connected inside the fixed block 10. A fixing plate 101 is fixedly connected to the side of the spring 102. The end of the fixing plate 101 away from the spring 102 is fixedly connected to the sliding block 11. The sliding block 11 and the first slide groove 4 have multiple sets of snap-fit ​​holes 6 on both sides to match each other. Two sets of sliding blocks 11 and fixing plates 101 are set in the fixed block 10. The ends of the two sets of sliding blocks 11 are T-shaped.

[0023] The following details the structure of the connection between the electronic digital dial indicator 7 and the second slide 5. Please refer to the following: Figures 1 to 4 A tension spring 13 is fixedly connected to the middle of the back of the electronic digital micrometer 7. A sliding plate 12 is fixedly connected to the end of the tension spring 13 away from the electronic digital micrometer 7. The sliding plate 12 is slidably connected in the second slide groove 5. The tension spring 13 fixedly connected to the middle of the electronic digital micrometer 7 is arranged in three sets. The three sets of tension springs 13 are evenly distributed and fixed on the surface of the sliding plate 12. The sliding plate 12 and the second slide groove 5 are snap-fitted. In this embodiment, a straight groove is opened on the inner side of the second slide groove 5. This is for the sliding plate 12 to slide in the straight groove opened in the second slide groove 5. This is to prevent the electronic digital micrometer 7 from falling out of the second slide groove 5, but it can still complete the up and down adjustment of the electronic digital micrometer 7.

[0024] Working principle: First, the operator holds the electronic digital dial indicator 7 and pulls it outward, causing the fixing block 10 and sliding block 11 fixed on the back of the electronic digital dial indicator 7 to be pulled out and disengaged into the first slide groove 4 and the snap-fit ​​hole 6, respectively. During the pulling of the electronic digital dial indicator 7, the tension spring 13 is simultaneously stretched. Then, as the operator adjusts the position of the electronic digital dial indicator 7 up and down, the electronic digital dial indicator 7 causes the tension spring 13 and the sliding plate 12 to slide in the second slide groove 5. The disengaged fixing block 10 and sliding block 11 also move up and down with the electronic digital dial indicator 7. After the operator confirms the up and down adjustment... After the adjusted distance meets the measurement standard, the staff needs to press the electronic digital micrometer 7 so that the fixing block 10 and sliding block 11 fixed on the back of the electronic digital micrometer 7 are pressed into the first slide groove 4 and the snap-fit ​​hole 6 respectively. During the pressing process, the sliding block 11 will be restricted by the first slide groove 4 and retract into the fixing block 10, and compress the spring 102. When the sliding block 11 is no longer restricted by the first slide groove 4, the spring 102 will automatically reset and expose the sliding block 11 and snap it into the snap-fit ​​hole 6, thereby fixing the electronic digital micrometer 7 after the up and down adjustment, without the need for the staff to repeatedly disassemble and install it by using bolts.

[0025] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
