[0002] A numerical control punching machine, fully known as a Computer Numerical Control Punching Machine, is an automated metal sheet processing equipment controlled by digital programs. It combines a precise mechanical system with an advanced electronic control system and can achieve precise punching and forming processing of complex shapes.

[0003] In the prior art, during the stamping process of sheet metal by a numerical control punching machine, the thickness of the sheet metal material has different effects on the processing accuracy, processing cost, equipment selection, performance of the processed product, and processing technological process. When detecting the thickness of a sheet metal part, the conventional method is to repeatedly measure by manually using measuring devices such as calipers to ensure accurate data and the development of subsequent processes. However, the conventional measuring devices have relatively simple structures and functions, and are easily interfered by external factors during measurement, resulting in the need for manual multiple measurements, which makes the detection work efficiency relatively poor. Content of the Utility Model

[0004] The purpose of the utility model is to provide a thickness detection device for an automatic loading machine of a numerical control punching machine to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A thickness detection device for an automatic loading machine of a numerical control punching machine, including: a bottom plate, a support table is arranged on the upper side of the bottom plate, a pressing plate is arranged on one side of the support table, and the pressing plate is slidably sleeved on a ruler column.

[0006] An upper screw rod is arranged on one side of the ruler column, an upper screw sleeve is sleeved on the upper screw rod, a width measuring plate is fixedly connected to the lower side of the upper screw sleeve, and a ruler frame is arranged on the upper side of the upper screw sleeve.

[0007] A lower screw rod is arranged on one side of the ruler frame, a lower screw sleeve is sleeved on the lower screw rod, and the upper surface of the lower screw sleeve is fixedly connected to the pulling end of a tape measure.

[0008] Preferably, the bottom plate and the support table are fixedly connected by welding through a connecting rod, two ruler columns are provided and are symmetrically arranged about the central plane of the support table, and a tension spring is installed on one side of the ruler column.

[0009] Preferably, one end of the tension spring is fixedly connected to the pressing plate, the other end of the tension spring is fixedly connected to a connecting block, both sides of the connecting block are slidably sleeved on short sliding rods, and both ends of the short sliding rods are fixedly connected to a first fixing seat.

[0010] Preferably, a second fixing seat is installed opposite to the first fixing seat. There are two first fixing seats and two second fixing seats, which are symmetrically arranged with respect to the central plane of the support table. The lower screw rod is rotatably sleeved on the first fixing seat and the second fixing seat on one side, and the fixing rod is fixedly sleeved on the first fixing seat and the second fixing seat on the other side.

[0011] Preferably, a limit sleeve is slidably sleeved on the fixing rod. The limit sleeve is fixedly connected to the lower screw sleeve through a U-shaped frame. The bottom of the U-shaped frame is slidably connected to the limit frame. The lower surface of the limit frame is fixedly connected to the bottom plate. The tape measure is fixedly connected to the upper surface of one of the first fixing seats.

[0012] Preferably, a fixing block is arranged on the upper side of the fixing rod. Both ends of the upper screw rod are rotatably sleeved in the fixing block. The upper surface of the fixing block is fixedly connected to the ruler frame, and the lower surface of the fixing block is fixedly connected to the output end of the electric cylinder.

[0013] Preferably, the lower surface of the electric cylinder is fixedly connected to the bottom plate. A limit rod is fixedly connected between the two fixing blocks. The upper screw sleeve is sleeved on the limit rod and is slidably connected to the limit rod.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. Under the pulling force of the tension spring, the pressing plate closely adheres to the upper surface of the sheet metal part. Thus, through the corresponding scales on the pressing plate and the ruler column, the thickness of the sheet metal part can be detected. Through the pulling of the tension spring, sheet metal parts with different thicknesses can be detected. At the same time, under the limitation of the short sliding rod, the connecting block is pulled to slide on it, so that the position of the pressing plate and the ruler column can be adjusted, and thus the thickness of different positions of the sheet metal part can be detected, improving the detection accuracy.

[0016] 2. By rotating the lower screw rod, the lower screw sleeve slowly drives the zero position of the pulling end of the tape measure to align with the edge of the sheet metal part first, and then continues to rotate the lower screw rod, so that the lower screw sleeve continues to drive the pulling end of the tape measure to move until the pulling end of the tape measure aligns with the other edge of the sheet metal part. Thus, by observing the scale on the tape measure, the length of the sheet metal part can be measured, and it is also convenient to detect the lengths of sheet metal parts with different lengths.

[0017] 3. By rotating the handwheel at one end of the upper screw rod, the upper screw rod is driven to rotate. There are two sections of threads on the upper screw rod with opposite helix directions. Under the limiting action of the limiting rod, the two upper screw sleeves on the upper screw rod can move towards each other, driving the width measuring plate to move, so that the width measuring plate clamps and fixes the sheet metal part. After the width measuring plate fixes the sheet metal part, the width of the sheet metal part can be detected by the ruler frame fixedly connected to the upper surface of the fixing block. At the same time, through the telescopic movement of the output end of the electric cylinder, the position between the width measuring plate and the sheet metal part can be conveniently adjusted, so as to better fix the sheet metal part, prevent the movement of the sheet metal part during the measurement process, improve the detection accuracy, make the data of the sheet metal part more complete, and the structure is simple and easy to operate, effectively improving the work efficiency of detection.

[0025] In order to clearly and completely describe the purpose and technical solution of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0026] Embodiment 1: Please refer to Figures 1-4, the present utility model provides a technical solution: a thickness detection device for an automatic loading machine of a numerical control punching machine, comprising: a bottom plate 1, a support table 2 is arranged on the upper side of the bottom plate 1, a pressing plate 3 is arranged on one side of the support table 2, the pressing plate 3 is slidably sleeved on a scale column 4, an upper screw rod 5 is arranged on one side of the scale column 4, an upper nut sleeve 6 is sleeved on the upper screw rod 5, a width measuring plate 7 is fixedly connected to the lower side of the upper nut sleeve 6, a scale frame 8 is arranged on the upper side of the upper nut sleeve 6, a lower screw rod 9 is arranged on one side of the scale frame 8, a lower nut sleeve 10 is sleeved on the lower screw rod 9, and the upper surface of the lower nut sleeve 10 is fixedly connected to the pulling end of a tape measure 11.

[0027] The whole device is stably supported by the bottom plate 1. The support table 2 is convenient for placing sheet metal parts. By the extension of the output end of the electric cylinder 23, the height of the scale frame 8 is adjusted. After adjusting to a suitable position, the pressing plate 3 is pulled upward to adjust the height of the pressing plate 3, so as to facilitate the placement of sheet metal parts on the support table 2. Then the pressing plate 3 is released to make the pressing plate 3 press on the upper surface of the sheet metal part, so that the thickness is detected through the scale on the pressing plate 3 and the scale column 4. Then, by the contraction of the output end of the electric cylinder 23, the width measuring plate 7 is brought close to the sheet metal part. Under the rotation of the upper screw rod 5, the upper nut sleeve 6 drives the width measuring plate 7 to clamp and fix both sides of the sheet metal part, so that the width of the sheet metal part can be detected through the scale frame 8. Finally, when the lower screw rod 9 rotates, the lower nut sleeve 10 moves on it, so that the lower nut sleeve 10 drives the pulling end of the tape measure 11 to be pulled out, and then the length of the sheet metal part is detected, making the data of the sheet metal part more complete, and the structure is simple and easy to operate, effectively improving the work efficiency of detection.

[0028] Embodiment 2: On the basis of Embodiment 1, the bottom plate 1 and the support platform 2 are fixedly welded by a connecting rod 12. There are two scale columns 4 which are symmetrically arranged with respect to the central plane of the support platform 2. A tension spring 13 is installed on one side of the scale column 4. One end of the connecting rod 12 is fixedly welded to the upper surface of the bottom plate 1, and the other end of the connecting rod 12 is fixedly welded to the lower surface of the support platform 2. One end of the tension spring 13 is fixedly connected to the pressing plate 3, and the other end of the tension spring 13 is fixedly connected to the connecting block 14. Both sides of the connecting block 14 are slidably sleeved on the short slide rod 15. Both ends of the short slide rod 15 are fixedly connected to the first fixing seat 16. The tension spring 13 is fixedly connected between the pressing plate 3 and the connecting block 14. The short slide rod 15 limits the connecting block 14. A second fixing seat 17 is installed opposite to the first fixing seat 16. There are two first fixing seats 16 and two second fixing seats 17, which are symmetrically arranged with respect to the central plane of the support platform 2. The lower screw rod 9 is rotatably sleeved on the first fixing seat 16 and the second fixing seat 17 on one side. The fixing rod 18 is fixedly sleeved on the first fixing seat 16 and the second fixing seat 17 on the other side. A limiting sleeve 19 is slidably sleeved on the fixing rod 18. The limiting sleeve 19 and the lower screw sleeve 10 are fixedly connected by a U-shaped frame 20. The bottom of the U-shaped frame 20 is slidably connected to the limiting frame 21. The lower surface of the limiting frame 21 is fixedly connected to the bottom plate 1. The tape measure 11 is fixedly connected to the upper surface of one of the first fixing seats 16. The fixing rod 18 limits the limiting sleeve 19, so that the limiting sleeve 19 limits the lower screw sleeve 10 through the connection of the U-shaped frame 20. The limiting frame 21 limits the U-shaped frame 20 when it slides.

[0029] When the sheet metal part is placed on the support platform 2 and fixed by the width measuring plate 7, at this time, the pressing plate 3 is tightly attached to the upper surface of the sheet metal part under the pulling force of the tension spring 13. Thus, through the corresponding scales on the pressing plate 3 and the scale column 4, the thickness of the sheet metal part can be detected. Through the pulling of the tension spring 13, sheet metal parts of different thicknesses can be detected. At the same time, under the limitation of the short slide rod 15, the connecting block 14 is pulled to slide on it, so that the positions of the pressing plate 3 and the scale column 4 can be adjusted, and thus the thickness of different positions of the sheet metal part can be detected, improving the detection accuracy. Then, by rotating the lower screw rod 9, since the lower screw sleeve 10 is threadedly connected to the lower screw rod 9, the lower screw sleeve 10 can be driven to move. The lower screw sleeve 10 is fixedly connected to the limiting sleeve 19 through the U-shaped frame 20. Thus, the limiting sleeve 19 is limited by the fixing rod 18, and the U-shaped frame 20 is limited by the limiting frame 21, and indirectly the lower screw sleeve 10 is limited, thereby improving the stability of the movement of the lower screw sleeve 10 and improving the measurement accuracy. The lower screw sleeve 10 slowly drives the zero position of the pulling end of the tape measure 11 to align with the edge of the sheet metal part first, and then continue to rotate the lower screw rod 9, so that the lower screw sleeve 10 continues to drive the pulling end of the tape measure 11 to move until the pulling end of the tape measure 11 aligns with the other edge of the sheet metal part. Thus, by observing the scale on the tape measure 11, the length of the sheet metal part can be measured, and it is also convenient to detect the lengths of sheet metal parts of different lengths.

[0030] Embodiment 3: On the basis of Embodiment 2, a fixing block 22 is arranged on the upper side of the fixing rod 18. Both ends of the upper screw rod 5 are rotatably sleeved in the fixing block 22. The upper surface of the fixing block 22 is fixedly connected to the ruler frame 8, and the lower surface of the fixing block 22 is fixedly connected to the output end of the electric cylinder 23. The fixing block 22 limits the upper screw rod 5, facilitating its rotation. The fixing block 22 is fixedly connected between the ruler frame 8 and the output end of the electric cylinder 23. The lower surface of the electric cylinder 23 is fixedly connected to the bottom plate 1. A limiting rod 24 is fixedly connected between the two fixing blocks 22. The upper nut sleeve 6 is sleeved on the limiting rod 24 and is slidably connected to the limiting rod 24. The bottom plate 1 is fixedly connected to the electric cylinder 23, ensuring the stability of the electric cylinder 23 during operation. The limiting rod 24 fixedly connected between the fixing blocks 22 limits the upper nut sleeve 6, facilitating the upper nut sleeve 6 to drive the width measuring plate 7 to move.

[0031] When the sheet metal part to be detected is placed on the support table 2, by rotating the handwheel at one end of the upper screw rod 5, the upper screw rod 5 is driven to rotate. Two sections of threads with opposite helix directions are provided on the upper screw rod 5. Thus, under the limiting action of the limiting rod 24, the two upper nut sleeves 6 of the upper screw rod 5 can move towards each other, driving the width measuring plate 7 to move and clamping and fixing the sheet metal part with the width measuring plate 7. After the width measuring plate 7 fixes the sheet metal part, the width of the sheet metal part can be detected through the ruler frame 8 fixedly connected to the upper surface of the fixing block 22. At the same time, through the telescopic movement of the output end of the electric cylinder 23, the position between the width measuring plate 7 and the sheet metal part can be adjusted, thereby better fixing the sheet metal part and preventing the movement of the sheet metal part during the measurement process, improving the detection accuracy.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
