Description

Technical Field

[0001] The present invention belongs to the technical field of integrated stoves, and in particular relates to a cutting height measuring device for an integrated stove glass tabletop and a measuring method thereof. Background Art

[0002] Integrated stove is a kitchen appliance that integrates multiple functions such as range hood, gas stove, disinfection cabinet, storage cabinet, etc. It is also called environmentally friendly stove or integrated environmentally friendly stove in the industry. It has the advantages of saving space, good fume extraction effect, energy saving, low consumption and environmental protection. The general integrated stove has an oil absorption rate of 95%. The higher the oil fume absorption rate, the better the quality. Some brands of integrated stoves have an oil fume absorption rate of 99.95%. The glass countertop is one of the components of the integrated stove. It can not only maintain the beauty of the integrated stove, but also facilitate the cleaning of the integrated stove operation countertop. In the production and processing of the glass countertop, cutting is one of the necessary processing steps for the glass countertop. In the cutting process, the actual cutting height of the glass countertop needs to be measured. In the prior art, manual actual measurement is generally used, and the human error rate is large, resulting in an increase in defective and scrap rates, increasing processing costs, and manual measurement, There are certain operational safety hazards. Summary of the invention

[0003] The purpose of the present invention is to provide a cutting height measuring device and a measuring method for an integrated stove glass tabletop in view of the deficiencies in the prior art. The overall structural design is reasonable. The workbench is driven to rotate 180° by a rotating member and cooperates with a cutting device to achieve a mode change between the two operations of measurement and cutting. The cutting height of the glass tabletop on the workbench is measured by a measuring component to ensure the measurement accuracy, thereby improving the subsequent cutting accuracy, reducing the defective rate and the scrap rate, and saving production costs. At the same time, the measuring component can also further verify the height of the glass tabletop after cutting. In the measuring method, the actual height of the glass tabletop to be cut is first measured, so that the required cutting height of the glass tabletop can be obtained, and then the cutting height data is fed back to the cutting device through a control system. The cutting device then cuts the glass tabletop according to the cutting margin. After the cutting is completed, the cut glass tabletop is measured again, so as to detect and verify the cutting quality. Once the cutting is deviated, the cutting device is calibrated and repaired in time to ensure the accuracy of the re-cutting and reduce the defective and scrap rates.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A cutting height measuring device for an integrated stove glass tabletop, characterized in that it includes a placing table, a workbench is placed on the top surface of the placing table, a rotating member is arranged at the center of the placing table, the rotating member is connected to the workbench, a measuring component is arranged above the placing table, the measuring component is located on one side of the rotating member, and the measuring component is fixedly connected to the placing table through a supporting frame.

[0006] Furthermore, the rotating part includes a rotating sleeve and a driving motor. The rotating sleeve is located at the center of the top surface of the placing table, the driving motor is located inside the placing table, the motor shaft of the driving motor is connected to the connecting rod at the bottom of the rotating sleeve, and a positioning plate is provided on the rotating sleeve. The positioning plate is fixed to the workbench with screws. The rotation of the driving motor drives the rotation of the rotating sleeve, and the rotating sleeve drives the synchronous rotation of the workbench through the positioning plate, thereby realizing the change of the working mode of the glass table top. When the workbench rotates to the bottom of the measuring component, the glass table top is in the stage of height measurement, and when the workbench rotates out of the measuring component, it cooperates with the cutting equipment to perform cutting operations on the glass table top. The design is ingenious and reasonable.

[0007] Furthermore, the measuring component includes a main measuring component, a mounting plate and an auxiliary measuring component. The main measuring component includes a main hydraulic cylinder and a main contact rod. The main hydraulic cylinder is fixed on a supporting frame. The end of a piston rod of the main hydraulic cylinder is fixedly connected to the mounting plate. A positioning ring is provided on an upper outer wall of the main contact rod. The positioning ring is screwed to a top surface of one end of the mounting plate, and the lower end of the main contact rod extends to the bottom of the mounting plate through a clamping hole at one end of the mounting plate. The main hydraulic cylinder drives the mounting plate to move up and down through the extension and contraction of the piston rod, and the mounting plate drives the main contact rod to move up and down, thereby actually measuring the height of the glass table top on the workbench. The measuring operation is automated, easy to use, the height measurement rate is fast, and the error rate existing in manual measurement is reduced.

[0008] Furthermore, a guide rod is threadedly connected on the top surface of the main contact rod, and the guide rod is clamped in the guide groove of the guide sleeve. A fixed frame is provided on the top of the guide sleeve, and the fixed frame is fixedly connected to the support frame. The connection between the guide rod and the main contact rod is realized by a threaded connection, thereby ensuring the firmness of the connection between the guide rod and the main contact rod. When the piston rod of the main hydraulic cylinder is extended and retracted up and down, the main contact rod is driven to rise and fall through the mounting plate, and when the main contact rod is lifted and lowered, the guide rod connected to the top thereof slides up and down in the guide groove of the guide sleeve, thereby effectively ensuring the verticality of the up and down movement of the main contact rod and improving the measurement accuracy.

[0009] Furthermore, the auxiliary measuring component is located at the other end of the mounting plate, and the auxiliary measuring component includes an auxiliary hydraulic cylinder and an auxiliary contact rod. The auxiliary hydraulic cylinder is located above the mounting plate, and the auxiliary hydraulic cylinder is fixed on the top surface of the mounting plate. The piston rod end of the auxiliary hydraulic cylinder is threadedly connected to the auxiliary contact rod, and the auxiliary contact rod is clamped in the clamping hole at the other end of the mounting plate. The lower end of the auxiliary contact rod extends through the through hole to the bottom of the mounting plate. Through the auxiliary cooperation of the auxiliary measuring component, the cutting height measurement range of the measuring component can be expanded. When the glass table top is cut, when the main contact rod has not touched the top surface of the glass table top when the main hydraulic cylinder is extended to the maximum displacement, the auxiliary hydraulic cylinder starts to drive the auxiliary contact rod to descend, and the height of the glass table top is measured by the auxiliary contact rod to ensure the smooth progress of the height measurement operation.

[0010] Furthermore, a sliding seat is fixedly connected to the auxiliary hydraulic cylinder, the sliding seat is clamped on the guide plate, a slider is arranged on the sliding seat, a sliding groove is arranged on the guide plate, the slider matches the sliding groove, the slider is clamped in the sliding groove and slides up and down along the sliding groove, the guide plate is welded and fixed to the support frame, and through further design of the sliding seat and cooperation with the guide sleeve, the verticality of the up and down movement of the mounting plate can be further guaranteed. When the main hydraulic cylinder drives the mounting plate to move up and down, the auxiliary hydraulic cylinder fixed with the mounting plate moves synchronously, and at the same time drives the sliding seat to slide up and down along the sliding groove on the guide plate through the slider. Due to the further restrictions of the slider and the sliding groove, the verticality of the auxiliary hydraulic cylinder's own structure and the verticality of the up and down movement of the mounting plate can be effectively guaranteed.

[0011] Furthermore, a positioning hole is provided on the top surface of the rotating sleeve, a positioning column is clamped in the positioning hole, an adjusting rod is provided on the top of the positioning column, the top of the adjusting rod is movably clamped in the limiting through-hole of the support frame, and the top threaded sleeve of the adjusting rod is connected with the limiting nut. The structural design is compact and reasonable, the positioning column is clamped in the positioning hole, and at the same time, the positioning column applies a certain downward pressure to the rotating sleeve, effectively limiting the horizontal and vertical displacements of the rotating sleeve, so that the rotating sleeve can only rotate axially, ensuring the structural stability of the rotation of the rotating sleeve, thereby facilitating the adjustment of the position of the workbench, and the top of the positioning column is clamped with the support frame through the adjusting rod, and then limited and pressed by the limiting nut to ensure the clamping performance of the positioning column in the positioning hole, and also facilitate the actual installation, positioning and disassembly of the rotating sleeve.

[0012] Furthermore, both the main hydraulic cylinder and the auxiliary hydraulic cylinder are hydraulic cylinders with built-in displacement sensors. Using hydraulic cylinders with built-in displacement sensors for both the main hydraulic cylinder and the auxiliary hydraulic cylinder can facilitate timely acquisition of actual measurement data and ensure the accuracy of the measurement data.

[0013] The measuring method using the above-mentioned cutting height measuring device for the glass table of an integrated stove is characterized by comprising the following steps:

[0014] 1) Measurement of initial position parameters:

[0015] (1) First, a 10 cm high horizontal test plate is placed on the workbench. The main hydraulic cylinder is started, and the piston rod of the main hydraulic cylinder is extended to drive the mounting plate to move downward until the bottom end surface of the main contact rod touches the top surface of the horizontal test plate. The moving length X of the piston rod of the main hydraulic cylinder is obtained by the built-in displacement sensor in the main hydraulic cylinder. X plus the actual height of the horizontal test plate is used to obtain the value X1, which is the distance between the bottom end surface of the main contact rod and the top surface of the workbench in the initial state. First, a horizontal test plate of known height is used to measure the distance between the bottom end surface of the auxiliary release rod and the top surface of the workbench in the initial state, so as to facilitate the subsequent measurement and calculation of the height of the glass table top.

[0016] (2) Then the auxiliary hydraulic cylinder is started, and the piston rod of the auxiliary hydraulic cylinder is extended to drive the auxiliary contact rod to move downward until the bottom end surface of the auxiliary contact rod touches the top surface of the horizontal test plate. The moving length of the piston rod of the auxiliary hydraulic cylinder is obtained by the built-in displacement sensor in the auxiliary hydraulic cylinder as X2, where X2 is the height difference between the bottom end surface of the auxiliary contact rod and the bottom end surface of the main contact rod in the initial state; at the same time, the height difference between the auxiliary contact rod and the main contact rod is measured, so as to facilitate the calculation of the height of the glass table when the auxiliary contact rod is measured;

[0017] (3) Reset the auxiliary hydraulic cylinder and the main hydraulic cylinder to their initial positions, and then remove the horizontal test plate;

[0018] 2) Measurement of cutting height of glass table to be cut:

[0019] (1) The glass table to be cut is placed on the workbench, and then the main hydraulic cylinder is started. The piston rod of the main hydraulic cylinder is extended to drive the mounting plate to move downward until the bottom end surface of the main contact rod touches the top surface of the glass table to be cut on the workbench. The moving length of the piston rod of the main hydraulic cylinder is obtained as X3 through the built-in displacement sensor in the main hydraulic cylinder, and the difference ΔX between X1 and X3 is calculated. The difference ΔX is the actual height of the glass table to be cut. Since X1 is the distance between the main contact rod and the top surface of the workbench in the initial state, and X3 is the height of the main contact rod from the top surface of the glass table placed on the workbench, it is obvious that there is a height difference of the glass table between the two values. Therefore, after obtaining the value of X3, the actual measured height of the glass table placed on the workbench can be clearly obtained by calculating the difference between X1 and X3.

[0020] (2) The actual height ΔX of the glass table to be cut measured in step (1) is calculated to be different from the actual design height X0 of the glass table to be cut, so as to obtain the required cutting height ΔX1 of the glass table to be cut, and the cutting height is fed back to the cutting device; the actual cutting allowance can be obtained by calculating the difference between the actual measured height of the glass table and the required height X0 of the glass table after cutting, and the control system can transmit the data to the cutting device, so as to facilitate the subsequent cutting operation of the glass table by the cutting device, ensure that the cutting amount is the cutting allowance, and improve the cutting accuracy;

[0021] 3) Cutting process of the glass table to be cut:

[0022] The driving motor rotates, driving the workbench to rotate 180°, so that the glass table to be cut is moved out from under the measuring component and positioned on the top surface of the other side of the placement table, and then the glass table to be cut on the workbench is cut with the cooperation of the cutting equipment;

[0023] 4) Detection of cutting height of glass table:

[0024] (1) After the cutting is completed, the driving motor rotates, driving the workbench to rotate 180°, so that the cut glass table is rotated to the bottom of the measuring component; the operation is reasonable, which facilitates the measuring component to detect and calibrate the height of the cut glass table;

[0025] (2) Then the main hydraulic cylinder is started, and the piston rod of the main hydraulic cylinder is extended to drive the mounting plate to move downward until the bottom end surface of the main contact rod touches the top surface of the glass table. The moving length of the piston rod of the main hydraulic cylinder is obtained as X4 through the built-in displacement sensor in the main hydraulic cylinder, and the difference ΔX2 between X1 and X4 is calculated, so that the actual height of the glass table after cutting is obtained as ΔX2; X1 is the distance between the main contact rod and the top surface of the working table in the initial state, and X4 is the height of the main contact rod from the top surface of the glass table after cutting. It is obvious that there is a height difference of the glass table after cutting between the two values, so after obtaining the value of X4, the actual height of the glass table after cutting can be clearly obtained by calculating the difference between X1 and X4;

[0026] (3) When the piston rod of the main hydraulic cylinder in the above step (2) is extended to the maximum value, the moving length of the piston rod of the main hydraulic cylinder is obtained by the built-in displacement sensor in the main hydraulic cylinder as X5, and when the bottom end surface of the main contact rod has not yet touched the top surface of the glass table, the auxiliary hydraulic cylinder is started, and the auxiliary hydraulic cylinder drives the auxiliary contact rod to move downward until the bottom end surface of the auxiliary contact rod touches the top surface of the glass table, and the moving length of the piston rod of the auxiliary hydraulic cylinder is obtained by the built-in displacement sensor in the auxiliary hydraulic cylinder as X6, and the sum of X5 and X6 minus the sum of X2 and X1 is calculated, and the difference between the two sums is ΔX3, thereby obtaining the actual height of the glass table as ΔX3; when the height of the glass table after cutting is low, the piston rod of the main hydraulic cylinder is extended to the maximum displacement when the main contact rod has not yet touched the top surface of the glass table When it can touch the top surface of the cut glass table, the auxiliary hydraulic cylinder is used to extend the auxiliary measurement to ensure the smooth progress of the inspection and verification. Since there is a height difference X2 between the main contact rod and the auxiliary contact rod in the initial state, the auxiliary contact rod moves a distance X6 minus X2 before the auxiliary contact rod exceeds the main contact rod. The excess movement length is added to the initial movement length X5 of the main contact rod. Only when the piston rod of the main hydraulic cylinder is long enough in the virtual state, the main contact rod can reach the final movement length after moving the excess movement length obtained by subtracting X6 from X2 and the movement length X5. The final movement length is subtracted from the distance X1 between the main contact rod and the top surface of the work table in the initial state, and the actual height of the cut glass table is obtained.

[0027] (4) Compare the actual height ΔX2 or ΔX3 of the glass table after cutting calculated in step (2) or step (3) with the designed height X0, and calculate the difference between ΔX2 or ΔX3 and X0. When the difference is within an error range of ± 0.5 mm, the actual cutting meets the requirements. When the difference exceeds the error range, a cutting error occurs in the cutting device, and the cutting device is adjusted and calibrated in time. By measuring the actual height of the glass table after cutting, the cutting accuracy is timely checked. When the cutting error is greater than the error range, the cutting device is adjusted and calibrated in time to ensure the accuracy of the next cutting, reduce the defective rate and scrap rate, and improve the final cutting accuracy of the product.

[0028] The present invention has the following beneficial effects due to the adoption of the above technical solution:

[0029] The overall structural design of the present invention is ingenious and reasonable. The rotating part drives the workbench to rotate 180 degrees, and cooperates with the cutting equipment to realize the mode conversion of the two operations of measurement and cutting. When the glass table top is rotated out from under the measuring component, the cutting equipment is used to cut the glass table top. When the glass table top is located directly under the measuring component, it is divided into two situations: one is to measure the actual height of the glass table top on the workbench through the measuring component, so as to calculate the required cutting height through the measured actual height, and then feed back the cutting height to the cutting equipment to ensure the subsequent cutting equipment to accurately cut the glass table top, reduce the defective rate and scrap rate, and save production costs; the other is to measure the height of the glass table top after cutting again through the measuring component, so as to verify the actual height of the glass table top after cutting, detect whether the cutting of the glass table top is qualified, select qualified products and unqualified products, and when unqualified products appear, it means that the cutting equipment has a cutting error, and the cutting equipment is adjusted and calibrated in time to ensure the accuracy of the next cutting.

[0030] The entire measurement process of the present invention is automated, and no manual operation is required, thereby reducing the measurement error rate and improving the measurement accuracy. In conjunction with the operating system, the measured data can be obtained in a timely manner, and the final required measurement parameter values ​​can be obtained through simple computer calculations. In the present invention, actual measurements are performed before cutting each glass table to determine the actual cutting allowance of each glass table, thereby customizing the cutting allowance for each glass table to ensure the actual cutting accuracy. In addition, each glass table is cut and tested, and a height test must be performed again after cutting to ensure that the cutting height meets the actual requirements. Once a cutting error occurs, the cutting equipment is adjusted and calibrated in a timely manner to improve the subsequent cutting quality and cutting accuracy, reduce the defective rate and scrap rate, and save costs and resources.

[0031] In the measuring method of the present invention, a horizontal test plate of known height is first used to measure the parameters in the initial state, and then the measuring component measures the cutting height of the glass table to be cut, and the measured displacement length and the parameters in the initial state are simply calculated to obtain the actual height of the glass table, and then the actual height of the glass table is compared with the height of the glass table required by the design, and the difference between the two is the required cutting height of the final glass table, and the cutting device performs customized cutting operations on the glass table according to the actual cutting margin to ensure the cutting quality, and after the cutting is completed, the measuring component measures the height of the cut glass table again, and firstly the measured displacement length and the parameters in the initial state are simply calculated to obtain the actual height of the glass table after cutting, and then the actual height is compared with the height of the glass table required by the design to determine whether the difference between the two is within the error range, thereby detecting and verifying the cutting quality of the glass table, detecting qualified products and unqualified products, and once a cutting error occurs, timely calibrating and repairing the cutting equipment to ensure the accuracy of the next cutting and reduce the defective and scrap rates.

DETAILED DESCRIPTION

[0044] like Figures 1 to 8 As shown, a cutting height measuring device for an integrated stove glass tabletop of the present invention comprises a placing table 1, and the placing table 1 supports and ensures the placing stability of the entire device. At the same time, the placing table 1 divides the top surface into two parts through a rotating sleeve 6, one side is a measuring station, and the other side cooperates with the cutting equipment and is a cutting station. A workbench 2 is placed on the top surface of the placing table 1, and a rotating part 3 is arranged at the center of the placing table 1, and the rotating part 3 is connected to the workbench 2. A measuring component 4 is arranged above the placing table 1, and the measuring component 4 is located on one side of the rotating part 3. The measuring component 4 is fixedly connected to the placing table 1 through a supporting frame 5.

[0045] The rotating member 3 includes a rotating sleeve 6 and a driving motor 7. The rotating sleeve 6 is located at the center of the top surface of the placement table 1. The driving motor 7 is located inside the placement table 1. The motor shaft 8 of the driving motor 7 is connected to the connecting rod 9 at the bottom of the rotating sleeve 6. A positioning plate 10 is provided on the rotating sleeve 6. The positioning plate 10 is fixed to the workbench 2 with screws. The rotation of the driving motor 7 drives the rotation of the rotating sleeve 6, and the rotating sleeve 6 drives the synchronous rotation of the workbench 2 through the positioning plate 10 to realize the change of the working mode of the glass table. When the workbench 2 rotates to the bottom of the measuring component 4, the glass table 32 is in the stage of height measurement. When the workbench 2 rotates out of the measuring component 4, it cooperates with the cutting equipment to cut the glass table 32. The design is ingenious and reasonable.

[0046] The measuring assembly 4 includes a main measuring assembly, a mounting plate 11 and an auxiliary measuring assembly 12. The main measuring assembly includes a main hydraulic cylinder 13 and a main contact rod 14. The main hydraulic cylinder 13 is fixed on the support frame 5. The piston rod end of the main hydraulic cylinder 13 is fixedly connected to the mounting plate 11. A positioning ring 16 is provided on the upper outer wall of the main contact rod 14. The positioning ring 16 is screwed to the top surface of one end of the mounting plate 11, and the lower end of the main contact rod 14 extends to the bottom of the mounting plate 11 through the clamping hole 15 at one end of the mounting plate 11. The main hydraulic cylinder 13 drives the mounting plate 11 to move up and down through the expansion and contraction of the piston rod, and the mounting plate 11 drives the main contact rod 14 to move up and down, thereby actually measuring the height of the glass table top 32 on the workbench 2. The measuring operation is automated, easy to use, fast in height measurement rate, high in measurement accuracy, and reduces the error rate existing in manual measurement.

[0047] A guide rod 17 is threadedly connected to the top surface of the main contact rod 14, and the guide rod 17 is clamped in the guide groove 26 of the guide sleeve 18. A fixing frame 19 is provided at the top of the guide sleeve 18, and the fixing frame 19 is fixedly connected to the support frame 5. The connection between the guide rod 17 and the main contact rod 14 is realized by a threaded connection, thereby ensuring the firmness of the connection between the guide rod 17 and the main contact rod 14. When the piston rod of the main hydraulic cylinder 13 is extended and retracted up and down, the main contact rod 14 is driven to rise and fall through the mounting plate 11. When the main contact rod 14 is lifted and lowered, the guide rod 17 connected to its top slides up and down in the guide groove 26 of the guide sleeve 18, thereby effectively ensuring the verticality of the up and down movement of the main contact rod 14 and improving the measurement accuracy.

[0048] The auxiliary measuring assembly 12 is located at the other end of the mounting plate 11. The auxiliary measuring assembly 12 includes an auxiliary hydraulic cylinder 20 and an auxiliary contact rod 21. The auxiliary hydraulic cylinder 20 is located above the mounting plate 11. The auxiliary hydraulic cylinder 20 is fixed on the top surface of the mounting plate 11. The piston rod end of the auxiliary hydraulic cylinder 20 is threadedly connected with the auxiliary contact rod 21. The auxiliary contact rod 21 is clamped in the clamping hole 15 at the other end of the mounting plate 11. The lower end of the auxiliary contact rod 21 extends through the through hole to the bottom of the mounting plate 11. Through the auxiliary cooperation of the auxiliary measuring assembly 12, the cutting height measurement range of the measuring assembly 4 can be expanded. When the glass table top 32 is cut, the main contact rod 14 has not touched the top surface of the glass table top 32 when the main hydraulic cylinder 13 is extended to the maximum displacement. The auxiliary hydraulic cylinder 20 starts to drive the auxiliary contact rod 21 to descend, and the height of the glass table top 32 is measured by the auxiliary contact rod 21 to ensure the smooth progress of the height measurement operation.

[0049] A sliding seat 22 is fixedly connected to the auxiliary hydraulic cylinder 20, and the sliding seat 22 is clamped on the guide plate 23. A slider 24 is arranged on the sliding seat 22, and a slide groove 25 is arranged on the guide plate 23. The slider 24 matches the slide groove 25, and the slider 24 is clamped in the slide groove 25 and slides up and down along the slide groove 25. The guide plate 23 is welded and fixed to the support frame 5. Through the further design of the sliding seat 22 and the cooperation with the guide sleeve 18, the verticality of the up and down movement of the mounting plate 11 can be further guaranteed. When the main hydraulic cylinder 13 drives the mounting plate 11 to move up and down, the auxiliary hydraulic cylinder 20 fixed with the mounting plate 11 moves synchronously, and at the same time drives the sliding seat 22 to slide up and down along the slide groove 25 on the guide plate 23 through the slider 24. Due to the further restrictions of the slider 24 and the slide groove 25, the verticality of the auxiliary hydraulic cylinder 20's own structure and the verticality of the up and down movement of the mounting plate 11 can be effectively guaranteed.

[0050] A positioning hole 27 is provided on the top surface of the rotating sleeve 6, and a positioning column 28 is clamped in the positioning hole 27. An adjusting rod 29 is provided on the top of the positioning column 28. The top of the adjusting rod 29 is movably clamped in the limiting through hole 30 of the support frame 5, and the top threaded sleeve of the adjusting rod 29 is connected with a limiting nut 31. The structural design is compact and reasonable. The positioning column 28 is clamped in the positioning hole 27. At the same time, the positioning column 28 gives a certain downward pressure to the rotating sleeve 6, which effectively limits the horizontal and vertical displacements of the rotating sleeve 6, so that the rotating sleeve 6 can only rotate axially, ensuring the structural stability of the rotation of the rotating sleeve 6, thereby facilitating the adjustment of the position of the workbench 2, and the top of the positioning column 28 is clamped with the support frame 5 through the adjusting rod 29, and then limited and pressed by the limiting nut 31 to ensure the clamping performance of the positioning column 28 in the positioning hole 27, which is also convenient for the actual installation, positioning and disassembly of the rotating sleeve 6.

[0051] Both the main hydraulic cylinder 13 and the auxiliary hydraulic cylinder 20 are hydraulic cylinders with built-in displacement sensors. Using both the main hydraulic cylinder 13 and the auxiliary hydraulic cylinder 20 as hydraulic cylinders with built-in displacement sensors can facilitate timely acquisition of actual measurement data and ensure the accuracy of the measurement data.

[0052] like Fig. 9 and Fig.10 As shown, a measuring method of a cutting height measuring device for an integrated stove glass table top 32 of the present invention comprises the following steps:

[0053] 1) Measurement of initial position parameters:

[0054] (1) First, a 10 cm high horizontal test plate is placed on the workbench 2. The main hydraulic cylinder 13 is started, and the piston rod of the main hydraulic cylinder 13 is extended to drive the mounting plate 11 to move downward until the bottom end surface of the main contact rod 14 touches the top surface of the horizontal test plate. The moving length X of the piston rod of the main hydraulic cylinder 13 is obtained by the built-in displacement sensor in the main hydraulic cylinder 13. X plus the actual height of the horizontal test plate is used to obtain a value X1, which is the distance between the bottom end surface of the main contact rod 14 and the top surface of the workbench 2 in the initial state. First, a horizontal test plate of known height is used to measure the distance between the bottom end surface of the auxiliary release rod and the top surface of the workbench 2 in the initial state, so as to facilitate the subsequent measurement and calculation of the height of the glass table 32.

[0055] (2) Then the auxiliary hydraulic cylinder 20 is started, and the piston rod of the auxiliary hydraulic cylinder 20 is extended to drive the auxiliary contact rod 21 to move downward until the bottom end surface of the auxiliary contact rod 21 touches the top surface of the horizontal test plate. The moving length of the piston rod of the auxiliary hydraulic cylinder is obtained by the built-in displacement sensor in the auxiliary hydraulic cylinder 20 as X2, where X2 is the height difference between the bottom end surface of the auxiliary contact rod 21 and the bottom end surface of the main contact rod 14 in the initial state; at the same time, the height difference between the auxiliary contact rod 21 and the main contact rod 14 is measured, so as to facilitate the calculation of the height of the glass table 32 when the auxiliary contact rod 21 is measured;

[0056] (3) Reset the auxiliary hydraulic cylinder 20 and the main hydraulic cylinder 13 to their initial positions, and then remove the horizontal test plate;

[0057] 2) Measurement of cutting height of the glass table 32 to be cut:

[0058] (1) The glass table 32 to be cut is placed on the workbench 2, and then the main hydraulic cylinder 13 is started. The piston rod of the main hydraulic cylinder 13 is extended to drive the mounting plate 11 to move downward until the bottom end surface of the main contact rod 14 touches the top surface of the glass table 32 to be cut on the workbench 2. The moving length of the piston rod of the main hydraulic cylinder 13 is obtained as X3 through the built-in displacement sensor in the main hydraulic cylinder 13, and the difference ΔX between X1 and X3 is calculated. The difference ΔX is the actual height of the glass table 32 to be cut. Since X1 is the distance between the main contact rod 14 and the top surface of the workbench 2 in the initial state, and X3 is the height of the main contact rod 14 from the top surface of the glass table 32 placed on the workbench 2, it is obvious that there is a height difference of the glass table 32 between the two values. Therefore, after obtaining the value of X3, the actual measured height of the glass table 32 placed on the workbench 2 can be clearly obtained by calculating the difference between X1 and X3.

[0059] (2) The actual height ΔX of the glass table 32 to be cut measured in step (1) is calculated to be different from the actual design height X0 of the glass table 32 to be cut, so as to obtain the required cutting height ΔX1 of the glass table 32 to be cut, and the cutting height is fed back to the cutting device; the actual cutting allowance can be obtained by calculating the difference between the actual measured height of the glass table 32 and the required height X0 of the glass table 32 after cutting, and the control system can transmit the data to the cutting device, so as to facilitate the subsequent cutting operation of the glass table 32 by the cutting device, ensure that the cutting amount is the cutting allowance, and improve the cutting accuracy;

[0060] 3) Cutting process of the glass table 32 to be cut:

[0061] The driving motor 7 rotates, driving the workbench 2 to rotate 180°, so that the glass table 32 to be cut is moved out from under the measuring component 4 and positioned on the top surface of the other side of the placing table 1, and then the glass table 32 to be cut on the workbench 2 is cut by the cooperation of the cutting equipment;

[0062] 4) Detection of cutting height of glass table top 32:

[0063] (1) After the cutting is completed, the driving motor 7 rotates, driving the workbench 2 to rotate 180°, thereby rotating the cut glass table 32 to the bottom of the measuring component 4; the operation is reasonable, which facilitates the measuring component 4 to detect and calibrate the height of the cut glass table 32;

[0064] (2) Then the main hydraulic cylinder 13 is started, and the piston rod of the main hydraulic cylinder 13 is extended to drive the mounting plate 11 to move downward until the bottom end surface of the main contact rod 14 touches the top surface of the glass table 32. The moving length of the piston rod of the main hydraulic cylinder 13 is obtained as X4 through the built-in displacement sensor in the main hydraulic cylinder 13, and the difference ΔX2 between X1 and X4 is calculated, so that the actual height of the glass table 32 after cutting is obtained as ΔX2; X1 is the distance between the main contact rod 14 and the top surface of the workbench 2 in the initial state, and X4 is the height of the main contact rod 14 from the top surface of the glass table 32 after cutting. It is obvious that there is a height difference of the glass table 32 after cutting between the two values, so after obtaining the value of X4, the actual height of the glass table 32 after cutting can be clearly obtained by calculating the difference between X1 and X4;

[0065] (3) When the piston rod of the main hydraulic cylinder 13 in the above step (2) is extended to the maximum value, the moving length of the piston rod of the main hydraulic cylinder 13 is obtained by the built-in displacement sensor in the main hydraulic cylinder 13 as X5, and when the bottom end surface of the main contact rod 14 has not yet touched the top surface of the glass table 32, the auxiliary hydraulic cylinder 20 is started, and the auxiliary hydraulic cylinder 20 drives the auxiliary contact rod 21 to move downward until the bottom end surface of the auxiliary contact rod 21 touches the top surface of the glass table 32. The moving length of the piston rod of the auxiliary hydraulic cylinder 20 is obtained by the built-in displacement sensor in the auxiliary hydraulic cylinder 20 as X6, and the sum of X5 and X6 minus the sum of X2 and X1 is calculated. The difference between the two sums is ΔX3, thereby obtaining the actual height of the glass table 32 as ΔX3; when the glass table 32 When the height after cutting is low, when the piston rod of the main hydraulic cylinder 13 is extended to the maximum displacement, the main contact rod 14 is still unable to touch the top surface of the glass table 32 after cutting, the auxiliary hydraulic cylinder 20 is used to perform auxiliary measurement to ensure the smooth progress of the inspection and verification. Since there is a height difference X2 between the main contact rod 14 and the auxiliary contact rod 21 in the initial state, the distance X6 moved by the auxiliary contact rod 21 is only the moving length of the auxiliary contact rod 21 beyond the main contact rod 14 after deducting X2. The excess moving length is added to the initial moving length X5 of the main contact rod 14. Only when the piston rod of the main hydraulic cylinder 13 is long enough in the virtual state, the main contact rod 14 can reach the final moving length after moving the sum of the excess moving length obtained by subtracting X2 from X6 and the moving length X5. The final moving length is subtracted from the distance X1 between the main contact rod 14 and the top surface of the workbench 2 in the initial state, and the actual height of the glass table 32 after cutting is obtained.

[0066] (4) Compare the actual height ΔX2 or ΔX3 of the glass table top 32 after cutting calculated in step (2) or step (3) with the designed height X0, and calculate the difference between ΔX2 or ΔX3 and X0. When the difference is within the error range of ±0.5 mm, the actual cutting meets the requirements. When the difference exceeds the error range, a cutting error occurs in the cutting device, and the cutting device is adjusted and calibrated in time. By measuring the actual height of the glass table top 32 after cutting, the cutting accuracy is timely checked. When the cutting error is greater than the error range, the cutting device is adjusted and calibrated in time to ensure the accuracy of the next cutting, reduce the defective rate and scrap rate, and improve the final cutting accuracy of the product.

[0067] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to achieve basically the same technical effects are all included in the protection scope of the present invention.
