Description

Technical Field

[0001] This utility model relates to the field of crystal rod cross-section measurement technology, specifically to a device for measuring the depth of a crystal rod cross-section. Background Technology

[0002] Monocrystalline silicon rods are a core material in the semiconductor, photovoltaic, and optoelectronic industries, playing a crucial role in many key areas of modern technology. However, it is not easy to pull monocrystalline silicon rods into complete rods during the production process, and wire breakage often occurs. In such cases, it is necessary to use a rod cross-sectional depth measuring device to measure the cross-sectional depth and rod diameter, thereby adjusting the pulling process.

[0003] In existing technologies, vernier calipers are mostly used for measurement. Vernier calipers can quickly measure the diameter of crystal rods, improving measurement efficiency, and also have strong wear resistance and are easy to read. Furthermore, they can be used to measure crystal rods at high temperatures, facilitating diameter adjustments.

[0004] However, existing vernier calipers are inconvenient for solo operation when measuring cross-sectional depth. Since the diameter of drawn crystal rods is generally over 200mm, measuring the depth requires a ruler placed at the cross-section. The vernier caliper is then held against the ruler while simultaneously measuring the distance from the bottom of the cross-section to the ruler to stabilize the caliper's position and angle and improve the accuracy of the measurement data. This requires multiple people working together, making the operation very inconvenient. Furthermore, because the depth varies at different locations on the cross-section, the vernier caliper needs to be moved to find the deepest point, further increasing the complexity of the operation. Moreover, the positions of the vernier caliper and ruler are prone to shifting during movement, leading to inaccurate measurement data. Utility Model Content

[0005] The purpose of this invention is to provide a device for measuring the cross-sectional depth of a crystal rod, which can quickly measure the cross-sectional depth of the crystal rod, and is simple to operate and has high measurement accuracy.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A device for measuring the depth of a crystal rod cross section is provided, including a vernier caliper. The vernier caliper includes a main scale, a ruler, and a depth measuring component. The depth measuring component includes a fixing block that is horizontally slidably mounted on the caliper body. One end of the fixing block has a groove, and the ruler is slidably connected to the groove. The ruler and the main scale are perpendicular to each other.

[0008] Furthermore, the number of fixing blocks is one pair and symmetrically arranged at both ends of the ruler. The depth measuring component also includes a pair of first screws, which pass through the top of the fixing blocks and are threadedly connected to them. The bottom of the first screws abuts against the top of the main ruler.

[0009] Furthermore, the depth measurement component also includes a pair of sliders. The sliders are T-shaped and fixedly connected to one side of the fixed block. A groove is provided on one side of the main scale, and the inner wall of the groove is slidably connected to the outer periphery of the sliders.

[0010] Furthermore, the vernier caliper also includes a vernier scale and a second screw. The inner wall of the vernier scale is slidably connected to the outer periphery of the main scale, and the second screw passes through the top wall of the vernier scale and is threadedly connected to it. The bottom of the second screw abuts against the top of the main scale.

[0011] Furthermore, measuring claws are fixedly connected to the bottom of one end of the main scale and the bottom of one end of the auxiliary scale, and the depth measuring component is located between the two measuring claws.

[0012] Furthermore, the vernier caliper also includes a limit block, which is fixedly connected to the other end of the main scale by bolts, and the other end of the vernier scale abuts against the limit block.

[0013] The beneficial effects of this utility model are as follows: By incorporating a vernier caliper, a fixed block, and a ruler, this utility model simplifies the measurement process when measuring the diameter and cross-sectional depth of a crystal rod. The operator uses one hand to operate the vernier caliper and the other hand to move the fixed block, extending the ruler to the deepest point of the cross-section. The ruler is then pushed to slide within the groove until it reaches the bottom of the cross-section, thus completing the measurement. Furthermore, it ensures that the ruler is perpendicular to the main scale, allowing for stable movement of the ruler to the deepest point of the cross-section and improving measurement accuracy. The ruler and fixed block are detachably connected; mounting the ruler on the fixed block allows for measurement of the cross-sectional depth, while removing the ruler avoids obstructing the vernier caliper's measuring stroke and does not affect its regular use.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent.

[0024] Reference Figures 1 to 4 The device for measuring the depth of a crystal rod cross section shown includes a vernier caliper 1, which includes a main scale 10, a ruler 15, and a depth measuring component 2. The depth measuring component 2 includes a fixing block 20, which is horizontally slidably mounted on the caliper body. One end of the fixing block 20 has a groove 200, and the ruler 15 is slidably connected to the groove 200. The ruler 15 is perpendicular to the main scale 10.

[0025] When measuring the diameter and depth of the crystal rod cross-section, the ruler 15 is first inserted into the slot 200. Then, the operator uses one hand to operate the vernier caliper 1, fixing the two measuring jaws 13 of the vernier caliper 1 to both ends of the crystal rod cross-section. With the other hand, the operator moves the fixing block 20 to move the ruler 15 to the deepest point of the cross-section. The ruler 15 is then pushed to slide within the slot 200 until it touches the bottom of the cross-section. Finally, the scale value on the ruler 15, aligned with the boundary of the main scale 10, is read, completing the measurement. This simplifies the measurement process and reduces the difficulty. Furthermore, the fixing block 20 ensures that the ruler 15 is perpendicular to the main scale 10. Rotating the main scale 10 and moving the fixing block 20 allows the ruler 15 to be stably moved to the deepest point of the cross-section, improving measurement accuracy.

[0026] The ruler 15 is detachably connected to the fixing block 20. The ruler 15 can be installed on the fixing block 20 to measure the cross-sectional depth. The ruler 15 can be removed to move the two fixing blocks 20 to the end of the main scale 10 near the measuring jaw 13 and fit together, so as to avoid occupying the measuring stroke of the vernier caliper 1 and not affect the normal use of the vernier caliper 1.

[0027] like Figure 4 As shown, there is a pair of fixing blocks 20 symmetrically arranged at both ends of the ruler 15. The depth measuring component 2 also includes a pair of first screws 21. The first screws 21 pass through the top of the fixing blocks 20 and are threadedly connected to them. The bottom of the first screws 21 abuts against the top of the main ruler 10.

[0028] By using two symmetrically arranged fixing blocks 20, first slide the two fixing blocks 20 to be spaced apart, and then insert the two ends of the ruler 15 into the two slots 200 respectively, the installation of the ruler 15 can be completed quickly, realizing a detachable connection. During operation, pushing the two fixing blocks 20 at the same time can move the ruler 15 horizontally. Then, rotating the first screw 21, through the threaded transmission between it and the fixing block 20, makes the first screw 21 abut against the top of the main ruler 10. Through friction, the fixing blocks 20 and the ruler 15 can be fixed in a suitable position.

[0029] like Figure 3 and Figure 4 As shown, the depth measuring component 2 also includes a pair of sliders 22. The sliders 22 are T-shaped and fixedly connected to one side of the fixed block 20. A groove 100 is provided on one side of the main scale 10. The inner wall of the groove 100 is slidably connected to the outer side of the sliders 22.

[0030] The slider 22 is limited by the inner wall of the slide groove 100, so that it slides horizontally along the slide groove 100, thereby realizing the horizontally slidable installation of the fixing block 20 on the main scale 10.

[0031] like Figures 1 to 4 As shown, the vernier caliper 1 also includes a secondary scale 11 and a second screw 12. The inner wall of the secondary scale 11 is slidably connected to the outer periphery of the main scale 10. The second screw 12 passes through the top wall of the secondary scale 11 and is threadedly connected to it. The bottom of the second screw 12 abuts against the top of the main scale 10.

[0032] Measuring claws 13 are fixedly connected to the bottom of one end of the main scale 10 and the bottom of one end of the auxiliary scale 11, and the depth measuring component 2 is located between the two measuring claws 13.

[0033] The vernier caliper 1 also includes a limiting block 14, which is fixedly connected to the other end of the main scale 10 by bolts, and the other end of the auxiliary scale 11 abuts against the limiting block 14.

[0034] The measuring jaws 13 on the main scale 10 are pressed against one end of the cross-section, and the main scale 10 is pressed against both ends of the top of the cross-section. Then, the auxiliary scale 11 is pushed to slide along the main scale 10, so that the measuring jaws 13 on the auxiliary scale 11 press against the other end of the cross-section. Then, the second screw 12 is rotated, and through the threaded transmission between it and the replica, the bottom of the second screw 12 is made to abut against the top of the main scale 10, and the auxiliary scale 11 is fixed by friction. Then, the scale of the vernier caliper 1 is read to complete the measurement of the crystal rod diameter. The depth measuring component 2 is located between the two measuring jaws 13. The other end of the main scale 10 is pressed against the auxiliary scale 11 by the limiting block 14, which can prevent the auxiliary scale 11 and the fixing block 20 from excessive displacement and slippage.

[0035] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
