Description

Technical Field

[0001] The present disclosure generally relates to the technical field of quartz tube measurement, and in particular to a length calibration device for measuring special-shaped quartz tubes. Background Art

[0002] The current application of quartz tubes in the field of lamps has demonstrated their excellent light transmittance, high temperature resistance, chemical stability and electrical insulation. These characteristics enable quartz tube lamps to provide efficient, stable and reliable light sources in various applications.

[0003] During the manufacturing process of quartz lamps, it is necessary to mark the diameter change point of the quartz tube according to the design length. By measuring the length of the marked point, other structural parameters of the subsequent quartz lamp tube are planned. Currently, the length of the diameter change point of the quartz tube is mostly measured by directly measuring the distance between the two marks using measuring tools such as a box ruler.

[0004] Although the above-mentioned length-taking method is simple to operate, the box ruler and the diameter-changing part of the quartz tube cannot be directly fitted together, which greatly increases the measurement error. If the measurement error is too large, it will directly lead to product scrapping. Therefore, we provide a length calibration device for measuring special-shaped quartz tubes to solve the above problem. Utility Model Content

[0012] The first support beam, the second support beam and the sliding guide rail are respectively used for supporting the measuring member, the fixing assembly and the calibration part.

[0013] According to the technical scheme provided in the application, the fixing part comprises two support rollers arranged on the second support beam along the second direction;

[0014] The axes of the two support rollers are parallel in the first direction, and the two support rollers in each fixing part form a fixing point of the quartz tube.

[0015] According to the technical scheme provided in the application, the calibration part comprises:

[0016] A sliding block, which is in sliding connection with the sliding guide rail;

[0017] A calibration plate, which is arranged on the top of the sliding block, has a calibration section extending to the outside of the sliding block along the second direction, and has a lower edge of the calibration section closely combined with the upper surface of the measuring member;

[0018] A calibration block, which is arranged on the calibration plate and located on the outer side of the calibration section close to the quartz tube, extends along the second direction towards the quartz tube, and the second direction is perpendicular to the first direction.

This device can accurately assist technicians in calibrating the length of the quartz tube at the varying diameter, thereby improving the accuracy of subsequent lengthening operations on the quartz tube.

DETAILED DESCRIPTION

[0029] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only portions relevant to the invention are shown in the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] Example 1

[0032] In order to make the technical solutions of the embodiments of the present application clearer and easier to understand, the application background of the embodiments of the present application is introduced below.

[0033] The current application of quartz tubes in the field of lamps has demonstrated their excellent light transmittance, high temperature resistance, chemical stability and electrical insulation. These characteristics enable quartz tube lamps to provide efficient, stable and reliable light sources in various applications.

[0034] During the manufacturing process of quartz lamps, it is necessary to mark the diameter change of the quartz tube so as to measure the exact length of the diameter change. This is because the size and shape of the quartz tube need to be precisely controlled. Measuring the length of the quartz tube at the diameter change can help manufacturers better control the position where the lamp tube transitions from one diameter to another, ensuring that the geometric shape of the lamp tube meets the design requirements. Currently, most measuring tools such as a box ruler are used to directly measure the distance between the marks on the quartz tube, which is used as the measurement data for the length of the diameter change.

[0035] Although the method of using a box ruler to mark the length is simple to operate, the box ruler cannot directly fit the diameter change part of the quartz tube, which greatly increases the measurement error. If the error is too large, it will directly lead to the scrapping of the product. For this reason, we provide a length calibration device for measuring special-shaped quartz tubes.

[0036] In view of this, please refer to Figure 3 The structure side view of a device for measuring the length of a special-shaped quartz tube provided by this embodiment includes:

[0037] The frame 1 has a top portion forming a mounting surface;

[0038] A fixing assembly is provided on the mounting surface; the fixing assembly includes at least two fixing portions 21 spaced apart along a first direction, the fixing portions 21 being used to support the quartz tube 3; the first direction is parallel to the length direction of the frame 1;

[0039] The calibration assembly is arranged on the mounting surface and adjacent to the fixing assembly; the calibration assembly comprises a measuring member 41 arranged along a first direction and two calibration parts 42 which are slidable along the measuring member 41.

[0040] The two calibration parts 42 are used to move along the measuring member 41 according to preset variable-diameter measuring positions, so as to calibrate the length of the variable-diameter part of the quartz tube 3 by the positions of the two calibration parts 42 on the measuring member 41.

[0041] In the embodiment, the frame body 1 is used to form the mounting space of the fixing assembly and the calibration assembly, and also provides favorable conditions for the overall movement of the length calibration device.

[0042] The fixing assembly is arranged on the top surface of the frame body 1 and comprises two fixing parts 21 which are arranged along a first direction and are spaced apart; the two fixing parts 21 can provide stable support for the quartz tube 3; the first direction is parallel to the length direction of the frame body 1, and the spacing distance of the two fixing parts 21 also needs to be set according to the length of the quartz tube to be processed.

[0043] The calibration assembly is also arranged on the top surface of the frame body 1 and is adjacent to the fixing assembly, so as to accurately calibrate the length of the quartz tube 3. The measuring member 41 in the calibration assembly provides sliding reference for the two slidable calibration parts 42; since the calibration parts 42 are mainly used to mark the length of the quartz tube, the calibration parts 42 can slide along the measuring member 41; since the length range to be measured is confirmed in advance by the technician, and the technician generally draws a line at the corresponding position (for example, the positions of the two drawn lines are the preset variable-diameter measuring positions, which are also the target positions to which the two calibration parts 42 need to move), the two calibration parts 42 can move according to the preset variable-diameter measuring positions which have been marked; finally, the length data to be measured in advance can be obtained by reading the position information of the two calibration parts 42 displayed on the measuring member 41, so as to complete the length calibration of the variable-diameter part of the quartz tube 3.

[0044] It should be noted that the number of the fixing parts 21 and the calibration parts 42 can be set according to actual conditions, and is not specifically limited.

[0045] In a preferred embodiment, referring to Figure 2 and Figure 3 , the frame body 1 comprises a first support beam 11 located at the top thereof, and a second support beam 12 and a sliding guide rail 13 located at both sides of the first support beam 11 respectively, and all of them extend along a first direction;

[0046] The first support beam 11, the second support beam 12 and the sliding guide rail 13 are respectively used to support the measuring member 41, the fixing assembly and the calibration parts 42.

[0047] A measuring piece 41 is provided on the first support beam 11. The measuring piece 41 can be a ruler or other types of measuring pieces, and there is no special limitation on the specific ones. The second support beam 12 and the sliding guide rail 13 are respectively located on both sides of the first support beam 11. The second support beam 12 is used to support the fixed part 21, and the sliding guide rail 13 is used to support the calibration part 42 with sliding requirements, so that the calibration part 42 can slide along the sliding guide rail 13.

[0048] In a preferred embodiment, see Figure 3 , the fixing portion 21 includes: two supporting rollers 22 arranged along the second direction and arranged on the second supporting beam 12;

[0049] The axes of the two supporting rollers 22 are parallel in the first direction, and the two supporting rollers 22 in each fixing portion 21 form a fixing point of the quartz tube 3 .

[0050] Each fixing portion 21 includes two supporting rollers 22 arranged along the second direction. A fixed point can be formed between the two supporting rollers 22 for the quartz tube 3. The two fixing portions 21 just form a stable support for the quartz tube 3. Specifically, the axes of the two supporting rollers 22 are parallel in the first direction, which is equivalent to the outer circumferential surfaces of the two supporting rollers 22 being arranged adjacent to each other. For details, see Figure 1 and Figure 3 The arrangement position in the middle provides stable support for the quartz tube 3.

[0051] It should be explained that in order to increase the friction between the support roller 22 and the quartz tube 3, fix the posture of the quartz tube 3, and also protect the quartz tube 3, in a preferred embodiment, the support roller 22 is further provided with a buffer body 23 around its circumference, and the buffer body 23 is made of elastic material, specifically rubber material.

[0052] In a preferred embodiment, see Figure 2 and Figure 3 , the calibration unit 42 includes:

[0053] A sliding block 43 is slidably connected to the sliding guide rail 13;

[0054] The calibration plate 44 is disposed on top of the sliding block 43. The calibration plate 44 has a calibration section extending along the second direction to the outside of the sliding block 43. The lower edge of the calibration section is in close contact with the upper surface of the measuring member 41.

[0055] The calibration block 45 is provided on the calibration plate 44 and is located at the outer side of the calibration section close to the quartz tube 3 ; the calibration block 45 extends along the second direction toward the quartz tube 3 ; the second direction is perpendicular to the first direction.

[0056] The sliding block 43 is slidably set on the sliding guide rail 13, and a calibration plate 44 is set on the top of it. In order to make the calibration plates 44 in the two calibration parts 42 closer to each other, for a small range of preset required lengths, the two calibration plates 44 can be respectively set at the sides of the two sliding blocks 43 close to each other.

[0057] In addition to being close to the quartz tube 3, the calibration portion 42 also needs to be in close contact with the measuring piece 41 to form a precise moving reference. Therefore, the calibration plate 44 has a calibration section extending along the second direction to the outside of the sliding block 43, and the lower edge of the calibration section needs to be in close contact with the upper surface of the measuring piece 41.

[0058] A calibration block 45 is provided on the calibration section of the calibration part 42. The calibration block 45 needs to be close to the quartz tube 3, specifically extending toward the quartz tube 3 along the second direction, where the second direction is a direction perpendicular to the length of the quartz tube 3. This design allows the calibration part 42 to move accurately with reference to the drawn line of the quartz tube 3, to assist technicians in quickly moving the sliding block 43.

[0059] In a preferred embodiment, see Figure 3 In order to prevent hard objects from damaging the quartz tube, the calibration block 45 here is made of elastic material, such as nylon. In order to improve the accuracy of calibration, the side of the calibration block 45 close to the quartz tube 3 is a pointed structure, which can further align with the drawn line of the quartz tube 3 to improve the accuracy of subsequent measurement data. It should be noted that the pointed structure should be close to a direct triangle, and the contact data between the edge of the calibration block where the right angle side is located and the measuring piece 41 will be more accurate as the reading value.

[0060] In addition, to avoid motion interference, the calibration block 45 needs to be set higher than the support roller 22 to ensure the normal movement of the sliding block 43. Therefore, the calibration block 45 needs to be located above the support roller 22 and also needs to be close to but not in contact with the quartz tube 3 on it.

[0061] In a preferred embodiment, see Figure 1 A plurality of rollers 14 are provided at the bottom of the frame 1 , and the rollers 14 are used to drive the frame 1 to move.

[0062] In order to facilitate the overall movement of the length calibration device, a plurality of rollers 14 are provided at the bottom of the frame 1. When the device is needed, the entire length calibration device can be pushed by the rollers 14, which greatly improves the mobility of the device.

[0063] Based on the above description, this application proposes a length calibration device for measuring special-shaped quartz tubes, and its specific working principle is as follows:

[0064] First, a technician makes a measurement mark in advance at the diameter change point of the quartz tube, or can directly move the slider 43 to the target position later based on experience, which is not particularly limited here.

[0065] Secondly, the quartz tube 3 is placed between the two support rollers 22 in each fixed portion 21. The sliding block 43 is then moved along the sliding guide rail 13, and the position of the calibration block 45 relative to the quartz tube 3 is observed. When the tip of the calibration block 45 reaches the mark or the set position, the movement of the two sliding blocks 43 is stopped. Finally, by reading the reading of the calibration plate 44 on the measuring piece 41 at this time, the readings of the two calibration plates 44 on the measuring piece 41 can be used as the diameter change length measurement data of the quartz tube 3. This length calibration device is not only simple in structure and easy for technicians to move and operate, but also takes into account the accuracy and convenience of measurement, and effectively solves the current problem of inaccurate length measurement at the diameter change of quartz tubes.

[0066] The above description is merely a preferred embodiment of the present application and an illustration of the technical principles employed. Those skilled in the art should understand that the scope of the invention herein is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but also encompasses other technical solutions formed by any combination of the above-mentioned technical features or their equivalents without departing from the inventive concept. For example, a technical solution formed by replacing the above-mentioned features with (but not limited to) technical features with similar functions disclosed in this application.
