[0002] One-button flash tester is an efficient and convenient measuring device, mainly used for fast and accurate measurement of objects of various sizes and shapes in industrial production and quality control. Existing one-button flash testers are all vertical structures. To measure the size of flat parts, you only need to place the parts on the measuring platform; but when measuring shaft parts, if the parts are symmetrical, they can be placed flat, but they may roll, which will affect the measurement of the flash tester; if the parts cannot be placed flat, the workpiece needs to be clamped to the center of the part, but this method will cause the image of the clamped part to be affected by the workpiece and cannot be measured. For such parts, customers generally need to use a horizontal flash tester, but the horizontal flash tester also has limitations; the horizontal flash tester is generally only for shaft parts, and the product placement angle requirements for flat parts are extremely high; if the product placement direction is not parallel to the flash tester's optical path direction, the measured image will be inconsistent with the actual object, resulting in inaccurate measured data. Developing a portable vertical and horizontal dual-purpose flash tester that can quickly, simply and stably measure all parts to meet user needs has become a technical problem that needs to be urgently solved by technical personnel in this field.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0026] In a specific implementation, the first direction, the second direction and the third direction are orthogonal to each other; the first direction is the X direction, the second direction is the Y direction, and the third direction is the Z direction.

[0027] like Figure 1 As shown, the utility model discloses a vertical and horizontal dual-purpose flash measuring instrument, comprising a mounting seat 1, a bearing member 2, a measuring mechanism 4 and a bracket 3; the bearing member 2 for bearing the workpiece to be measured is arranged on the upper surface of the mounting seat 1; the measuring mechanism 4 and the bearing member 2 for measuring the size of the workpiece are arranged opposite to each other; the bearing member 2 and the measuring mechanism 4 are simultaneously arranged on the same side of the bracket 3, and the bracket 3 is used to fix and support the bearing member 2 and the measuring mechanism 4.

[0028] Preferably, the bearing member 2 is moved along the third direction by the lifting knob 5. When the workpiece is not within the measuring range of the measuring mechanism 4, the position of the workpiece can be changed by moving the bearing member 2 so that the workpiece is within the measuring range of the measuring mechanism 4, so that the workpiece to be measured reaches the optimal distance for measurement.

[0029] The bearing member 2 includes a vertical stage 21 and a horizontal stage 22; the vertical stage 21 is arranged on the upper surface of the mounting seat 1, the upper surface of the mounting seat 1 is parallel to the plane composed of the first direction and the second direction, the plane where the horizontal stage 22 is located is parallel to the plane composed of the second direction and the third direction, and the horizontal stage 22 is arranged on the side of the vertical stage 21 close to the bracket 3 to ensure that the horizontal stage 22 has no influence on the measurement of the vertical stage 21 during the measurement process.

[0030] like Figure 1 When the flash tester is used vertically, the vertical stage 21 is used to place the workpiece. After the workpiece is stably placed, the measuring mechanism 4 can measure the size of the workpiece to be measured and quickly obtain the required results.

[0031] Preferably, the vertical stage 21 is designed to be integrated with the telecentric light source. The telecentric light source is emitted from the inside of the vertical stage 21, that is, it serves as the backlight source of the workpiece. The measuring mechanism 4 can measure the dimensional data such as the through holes and outer contours of the object. For blind holes or dimensions on the surface of the object to be measured, it is necessary to cooperate with the coaxial light source of the measuring mechanism 4 to illuminate the upper surface of the product, so that the measuring mechanism 4 can complete the measurement of the dimensional data. The integrated design reduces the number of components, simplifies the assembly process, and reduces the cost of assembly and debugging. During the design process, the illumination angle and intensity of the telecentric light source are adjusted to ensure measurement accuracy. According to the design requirements, after the assembly of the vertical stage 21 and the telecentric light source is completed, use measuring tools for debugging and calibration to ensure that the measurement accuracy meets the requirements.

[0032] like Figure 2-3When the flash tester is used horizontally, the horizontal stage 22 is used to place the workpiece. After the workpiece is stably placed, the measuring mechanism 4 can measure the size of the workpiece to be measured and quickly obtain the required results. For example, for special-shaped parts, such as bolts with threads, the bolts can be stably placed on the horizontal stage 22, and the measuring mechanism 4 can measure the size of the threads.

[0033] Preferably, the middle position of the horizontal stage 22 is connected to the mounting seat 1 by bolts, and the horizontal stage 22 is stably fixed on the mounting seat 1; at the same time, the junction of the horizontal stage 22 and the mounting seat 1 is positioned by multiple groups of symmetrically arranged high-precision stage pins 61, and the positioning holes on the horizontal stage 22 are installed in coordination with the stage pins 61 on the mounting seat 1 to ensure the accuracy of the installation position of the horizontal stage 22.

[0034] Before manufacturing, the bracket 3 is modeled and simulated by finite element analysis software, such as Soildworks; according to the analysis results, the hollowing and strengthening areas of the bracket 3 are determined to optimize the structural performance of the bracket 3, ensure the strength of the bracket 3 while reducing the weight, and improve the stability and portability of the flash tester. According to the analysis results, a processing drawing is prepared to indicate the specific positions and sizes of the bracket 3 that can be hollowed out and need to be strengthened, which is used as a reference for later processing.

[0035] Preferably, the support 3 reduces the volume and height by 10%, thereby improving portability.

[0036] Further preferably, the bracket 3 is processed by high-strength materials, such as aluminum alloy, steel, etc., to improve the strength and stability of the bracket 3, and ensure that the flash tester is not affected in both vertical and horizontal use states.

[0037] Further preferably, the bracket 3 is cut, drilled and welded using high-precision equipment to ensure the accuracy and quality of the bracket 3; high-precision equipment such as: horizontal CNC machining center, slow-wire cutting machine, surface grinder, to ensure that the accuracy of the manufactured parts can meet the requirements.

[0038] Further preferably, after the bracket 3 is assembled, a measuring tool is used to detect its deformation to ensure that the deformation is less than 0.04 mm; the measuring tool is such as a lever micrometer or a high-precision measuring tool to ensure the accuracy of the measurement result. After the deformation is detected, a strength and stability test is performed to ensure that the bracket 3 meets the use requirements.

[0039] Preferably, the bracket 3 is provided with bolt positions, and for bolts that do not require adjustment or require only one adjustment, thread glue is applied to the contact surfaces of the bolts and nuts, and the bolts are tightened to ensure the stability of the bolt connection.

[0040] like Figure 3The bracket 3 includes a lens fixing plate 31, a vertical plate 32 and a stabilizing plate 33; the vertical plate 32 is located on a plane formed by the second direction and the third direction, and the bottom of the vertical plate 32 is fixedly connected to the mounting seat 1; the stabilizing plate 33 is located on a plane formed by the first direction and the third direction, and the stabilizing plate 33 is symmetrically arranged on the side of the vertical plate 32 away from the mounting seat 1. Two parallel stabilizing plates 33 are symmetrically and vertically fixed at the left and right ends of the vertical plate 32. The stabilizing plate 33 is bolted to the vertical plate 32 to ensure the stability of the flash tester when used in a vertical or horizontal position.

[0041] Preferably, the vertical plate 32 and the stabilizing plate 33 have the same height.

[0042] The plane where the lens fixing plate 31 is located is parallel to the plane where the stabilizing plate 33 is located. The lens fixing plate 31 is symmetrically and vertically fixed to the upper part of the vertical plate 32 close to the mounting seat 1. The two parallel lens fixing plates 31 support and fix the measuring mechanism 4. The lens fixing plate 31 is bolted to the vertical plate 32 to ensure the stability of the lens fixing plate 31.

[0043] Preferably, the height of the lens fixing plate 31 is smaller than the height of the vertical plate 32 .

[0044] Further preferably, a plurality of groups of high-precision bracket pins 62 are used for positioning between the lens fixing plate 31 and the vertical plate 32, and the installation positions of the bracket pins 62 are evenly arranged along the junction between the lens fixing plate 31 and the vertical plate 32, and the positioning holes on the lens fixing plate 31 are installed in coordination with the bracket pins 62 on the vertical plate 32, thereby ensuring the accuracy of the installation position of the lens fixing plate 31.

[0045] Further preferably, the lens fixing plate 31 is connected to the measuring mechanism 4 via bolts.

[0046] like Figure 3-4 The measuring mechanism 4 mainly includes a double telecentric lens assembly 41 and a lifting frame 42. The double telecentric lens assembly 41 is mounted in the middle of the lens fixing plate 31 and connected by bolts. The double telecentric lens assembly 41 is opposite to the vertical stage 21, ensuring that the coaxial light source in the double telecentric lens assembly 41 is vertically irradiated to the surface of the vertical stage 21. The lifting frame 42 is arranged at the lower part of the side of the vertical plate 32 away from the mounting seat 1. The lifting frame 42 controls the lifting and lowering of the telecentric light source, so that the measurement of the workpiece is clearer and more accurate.

[0047] The dual telecentric lens assembly 41 includes a dual telecentric lens 411, a first connecting body 412 and a first flange 413; the lower end of the first connecting body 412 is fixedly connected to the upper end of the dual telecentric lens 411, and a first flange 413 is fixedly provided at the connection, and the first flange 413 is fixedly connected to the lens fixing plate 31 through the fixing flange 43.

[0048] The first connector 412 extends to the other side of the vertical plate 32 through the groove at the upper end of the vertical plate 32 for mounting a camera; the bi-telecentric lens 411 is opposite to the vertical stage 21. To ensure the verticality of the light source, the staff needs to adjust the bi-telecentric lens assembly 41 during the assembly process to ensure that the position of the adjusted bi-telecentric lens assembly 41 is accurate and stable.

[0049] The edge of the fixed flange 43 extends and is mounted on the upper end of the lens fixing plate 31, and the two are connected by bolts; the first flange 413 is placed above the fixed flange 43, and the two are connected by bolts, and double-stacked self-locking gaskets 8 are used to reinforce the nut and the first flange to ensure that the bolts will not loosen under vibration or impact.

[0050] A precision gasket 7 is added between the first flange 413 and the fixed flange 43, which is used to adjust the angle of the double telecentric lens assembly 41, ensure the parallelism of the double telecentric lens assembly 41 and the telecentric light source, and realize the parallelism of the light receiving path of the double telecentric lens assembly 41 and the light emitting path of the telecentric light source, thereby ensuring the accuracy and stability of the measurement.

[0051] Preferably, the anti-loosening nut can replace the double-stacked self-locking gasket 8 to fix the structure.

[0052] Preferably, the specifications of the precision gasket 7 are 0.01 mm, 0.02 mm, 0.05 mm and 0.1 mm. The precision gasket 7 of appropriate thickness is selected according to actual conditions.

[0053] Further preferably, the material of the precision gasket 7 is a precision stainless steel gasket, which ensures that the dual telecentric lens assembly 41 maintains stability after adjustment, avoids the instability of the dual telecentric lens assembly 41 when used in two different modes, vertical or horizontal, and ensures the accuracy of the measurement results.

[0054] like Figure 4 The lifting frame 42 is fixed to the vertical plate 32 by bolts to ensure the stability of the lifting frame 42; at the same time, the four corners of the lifting frame 42 are positioned by high-precision lifting frame pins 63, and the positioning holes on the lifting frame 42 are installed in coordination with the lifting frame pins 63 on the vertical plate 32 to ensure the accuracy of the installation position of the lifting frame 42.

[0055] The production process of the vertical and horizontal dual-purpose flash tester is as follows:

[0056] S1. Use finite element analysis software to model and simulate the internal bracket. According to the simulation results, determine the hollowing and strengthening areas of the bracket to optimize the structural performance and ensure the strength of the bracket 3 while reducing the weight.

[0057] S2. According to the results of finite element analysis, make processing drawings to indicate the specific positions and sizes of hollowing and strengthening. Select high-strength materials such as aluminum alloy or steel for processing and manufacturing. During the processing, use high-precision equipment such as horizontal CNC machining centers, slow-wire cutting machines, surface grinders, etc. to perform cutting, drilling and other operations to ensure the accuracy and quality of bracket 3.

[0058] After S3 and bracket 3 are manufactured, assemble the brackets by bolts. Use a micrometer to check the deformation of the bracket to ensure that it is less than 0.04 mm. Perform strength and stability tests to ensure that the frame meets the design requirements.

[0059] S4, then fix and assemble the mounting seat 1, the bearing member 2, the measuring mechanism 4 and the bracket 3.

[0060] S5. Adjust and reinforce the assembled flash tester. Use high-precision pins to position the horizontal stage 22, lens fixing plate 31, and lifting frame 42. The installation position of the pins should be accurately matched and tightened to ensure positioning accuracy.

[0061] For the positions of the telecentric light source and lens that need to be adjusted, use 0.01mm, 0.02mm, 0.05mm or 0.1mm precision stainless steel gaskets to fine-tune the angle to achieve parallelism between the light-receiving optical path of the double telecentric lens assembly 41 and the light-emitting optical path of the telecentric light source, thereby ensuring the accuracy and stability of the measurement and ensuring that the adjusted position is accurate and stable.

[0062] For bolted connections on the flash tester that do not require adjustment or only require one adjustment, apply thread glue to the contact surface of the bolt and nut, and then tighten. For locations that require multiple adjustments such as telecentric light sources and lenses, use double-stacked self-locking washers 8 or anti-loosening nuts to secure them to ensure that the bolts will not loosen under vibration or impact.

[0063] S6. Strict quality control measures are implemented throughout the manufacturing and assembly process to ensure that each step of the operation meets the design requirements. The flash tester that meets the requirements is given a casing to ensure the beauty of the device.

[0064] S7. Carry out comprehensive inspection and testing of finished products with a height of 700mm, including appearance inspection, performance testing and safety assessment, to ensure that the products meet the predetermined quality standards. Before the equipment leaves the factory, a 24-hour vibration test is carried out. During the test, the vibration environment that the equipment may encounter during transportation is simulated, and the tightening of bolts and other components is observed.

[0065] S8. Make necessary adjustments and improvements to the equipment based on the test results to ensure that the equipment can maintain stable performance after long-term transportation.
