Description

Technical Field

[0001] The invention belongs to the technical field of steel plate thickness detection, in particular to a cold-rolled steel plate thickness gauge. Background Art

[0002] Cold-rolled steel plates are made from hot-rolled coils and rolled at room temperature. During the production process, the thickness of cold-rolled steel plates needs to be measured. By measuring the thickness of cold-rolled steel plates, it can be determined whether the thickness of the cold-rolled steel plates meets the standards.

[0003] Patent announcement number CN218994244U discloses a steel plate thickness detection device, belonging to the field of steel plate thickness detection technology. It includes a table body and three measuring columns. The table body is composed of a top plate, several supporting legs, and a bottom plate. The three measuring columns are fixedly mounted on one end of the top surface of the top plate. The measuring columns are provided with mounting slots on the side facing the center of the top plate. A first screw is rotatably mounted in the mounting slot. The first screw is threaded with a measuring rod that slides and fits in the mounting slot. A second screw is rotatably connected to both sides of the end of the top surface of the bottom plate away from the measuring column. The second screw is threaded with a lifting plate. The lifting plate has several through holes. The bottom surface of the lifting plate is fixedly connected to a U-shaped plate downwardly. The U-shaped plate is fixedly mounted with a rolling assembly. The three first screws pass through the top plate and are downwardly connected to the first transmission assembly. By providing the second screw and lifting plate, the patent realizes the automatic lifting of the steel plate, eliminating the need for manual transportation to the measurement position.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] The steel plate is placed in a fixed measuring area for measurement, and after the measurement is completed, the steel plate can be pushed to slide to the ground. Although this method can save manpower to carry the measured steel plate down, usually, multiple steel plates are measured in sequence, and the measured steel plates are divided into qualified thickness and unqualified thickness. If all the measured steel plates slide to the same position, the qualified thickness and unqualified thickness steel plates will be mixed together, which may cause the unqualified steel plates to be put into subsequent processing and production, thereby affecting the quality of the steel plates. In addition, the fallen steel plates are relatively messy, which is not conducive to unified transfer to subsequent processes. When workers manually classify the qualified thickness and unqualified thickness steel plates, and organize the fallen steel plates, the labor intensity of the workers will increase.

[0006] To this end, the present invention provides a cold-rolled steel plate thickness gauge. Summary of the Invention

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The cold-rolled steel plate thickness gauge described in the present invention places the cold-rolled steel plate to be measured on a conveyor belt, with the ultrasonic probe above the cold-rolled steel plate. Then, a motor (7) drives a threaded rod (4) to rotate, so that a lifting plate drives the ultrasonic probe to contact the cold-rolled steel plate. The ultrasonic probe transmits ultrasonic pulses that propagate inside the cold-rolled steel plate to be measured. When the ultrasonic pulses encounter the bottom surface of the cold-rolled steel plate, they are reflected. The reflected waves are received and their propagation time is calculated to obtain the thickness of the steel plate. This eliminates the need for manual measurement by holding the ultrasonic probe in contact with the cold-rolled steel plate, and is more convenient.

[0023] 2. The cold-rolled steel plate thickness gauge of the present invention utilizes an adjustable bearing mechanism and a limit adjustment mechanism to place steel plates with qualified thickness on the bearing plate, while steel plates with unqualified thickness fall into a collection box, thereby realizing the separation of steel plates with qualified thickness and steel plates with unqualified thickness, avoiding the situation where steel plates with unqualified thickness are put into subsequent processing and production together, ensuring the processing quality of the steel plates, and eliminating the need for workers to manually separate steel plates with qualified thickness and steel plates with unqualified thickness, saving manpower. Moreover, each time a steel plate is placed on the bearing plate, the dial plate can be used to push the flat steel plate to make it stand up, thereby allowing multiple steel plates with qualified thickness to be placed in an upright state, thereby reducing the horizontal placement space of the bearing plate occupied by each steel plate, and increasing the number of steel plates that can be placed on the bearing plate. Moreover, when it is necessary to collect the steel plates on the bearing plate, the stabilizing plate can be driven to move and approach the steel plate, and the steel plate can be clamped by the stabilizing plates on both sides. The collecting container is placed under the steel plate and contacts the bottom of the steel plate. Even if the steel plate is separated from the load-bearing plate at this time, the steel plate will remain neat under the action of the two stabilizing plates and will not deviate or tip over. Then the stabilizing plate will move away from the steel plate, so that multiple steel plates can be neatly placed in the collecting container in an upright state, avoiding the situation where the transportation efficiency is affected by the disorder of the steel plates. Moreover, when the steel plate is clamped by the two stabilizing plates, the pushing block is made to contact the steel plate on either the leftmost or rightmost side, and then the pushing block is driven to move horizontally, and the upright steel plate can be pushed by the pushing block. After the multiple steel plates are subjected to external force, they will uniformly tip over in one direction. At the same time, the two sides of the steel plates are limited by the stabilizing plates. Therefore, the multiple steel plates will be arranged in an inclined state in the collecting container. Although the steel plates tip over, the adjacent steel plates are in contact, and the tipping angle and direction are uniform. This method can ensure the neatness of the steel plates, and will not cause the tilting directions of multiple upright steel plates to be inconsistent due to the external force on the collection container, resulting in messy steel plates. This further ensures the neatness of the steel plates and is conducive to transportation. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the adjusting rod 11 is fixedly connected to the motor 4 33, and the output end of the motor 4 33 is fixedly connected to one end of the threaded rod 5 32. One side of the slider 35 is fixedly connected to the motor 5 34, and the output end of the motor 5 34 is fixedly connected to one end of the dial plate 36.

[0050] Two sliding rods 6 38 are fixedly connected to one side of the supporting plate 16, and the sliding rod 6 38 is slidably connected to the connecting plate 37. Two sliding rods 7 42 are slidably connected to one side of the connecting plate 37. One end of the sliding rod 7 42 is fixedly connected to the stabilizing plate 17, and the stabilizing plate 17 can pass through the groove on one side of the supporting plate 16. A spring 39 is sleeved on one side of the sliding rod 7 42, and one end of the spring 39 is fixedly connected to the connecting plate 37, and the other end is fixedly connected to the stabilizing plate 17. An electric push rod 3 41 is fixedly connected to one side of the supporting plate 16, and the piston end of the electric push rod 3 41 is fixedly connected to one side of the connecting plate 37.

[0051] Specifically, in the existing steel plate thickness detection device, when in use, the steel plate is placed in a fixed measurement area for measurement, and after the measurement is completed, the steel plate can be pushed to slide to the ground. Although this method can remove the steel plate after measurement without manpower, usually, multiple steel plates are measured in sequence, and the measured steel plates are classified into qualified thickness and unqualified thickness. If all the measured steel plates slide to the same position, the qualified thickness and unqualified thickness steel plates will be mixed together, so that the unqualified steel plates may be put into subsequent processing and production, thereby affecting the quality of the steel plates. In addition, the fallen steel plates are relatively messy, which is not conducive to uniform transfer to subsequent processes. When workers manually classify the qualified thickness and unqualified thickness steel plates, and sort out the fallen steel plates, the labor intensity of the workers is increased.

[0052] Therefore, in order to solve the above problem, this embodiment is used for multiple steel plates of the same specification in the same batch. Thickness measurement of steel plates of the same specification in the same batch is a common situation in steel plate production and processing. After the thickness of a steel plate is measured, the thickness data of the steel plate will be displayed on the display screen of the thickness measuring device 4. The conveyor belt 3 drives the steel plate to move, and the motor 30 drives the two-way threaded rod 29 to rotate, so that the two clamping plates 28 approach each other, and the clamping plates 28 clamp the steel plate. If the thickness of the steel plate is unqualified, the motor 8 45 drives the threaded rod 3 24 to rotate, so that the slide plate 5 moves in the direction away from the carrying plate 16. Then, the worker can place a collection box for collecting steel plates with unqualified thickness at the end of the conveyor belt 3. When the steel plate is aligned with the opening of the collection box, the clamping plate 28 loosens the steel plate, and the conveyor belt 3 continues to operate, so that the steel plate with unqualified thickness can fall into the collection box for collection.

[0053] If the steel plate is of qualified thickness, the clamping plate 28 drives the steel plate to approach the carrying plate 16, and according to the width of the steel plate, the motor 9 46 can be used to drive the bidirectional threaded rod 19 to rotate, so that the two carrying plates 16 are close to each other, and the inner angle of the carrying plate 16 is aligned with the edge of the steel plate. At this time, the steel plate can be moved between the two carrying plates 16 along with the conveyor belt 3, and because the carrying plate 16 is in an inclined state, the steel plate will slide down to the end of the carrying plate 16 under the action of gravity, and then repeat the above operation. The steel plate with qualified thickness will be arranged in sequence and placed between the two carrying plates 16, thereby realizing the separation of steel plates with qualified thickness and steel plates with unqualified thickness, avoiding the situation that steel plates with unqualified thickness are put into subsequent processing and production together, ensuring the processing quality of the steel plates, and eliminating the need for workers to manually separate the steel plates with qualified thickness and steel plates with unqualified thickness, saving manpower.

[0054] The second step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate. At the same time, the third step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate. At the same time, the third step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate. At the same time, the third step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate. At the same time, the third step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate. At the same time, the third step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate. At the same time, the third step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate.

[0055] When a sufficient number of steel plates are collected on the carrying plate 16 and the steel plates on the carrying plate 16 need to be collected, the motor 12 can be used to drive the threaded rod 9 to rotate so that the adjusting rod 11 is moved away from under the carrying plate 16. At this time, the worker can place the collection container or the transport trolley under the carrying plate 16 and drive the slide plate 8 to rotate by the extension and contraction of the hydraulic cylinder 10 to make the carrying plate 16 horizontal. Then, the motor 946 is used to drive the two-way threaded rod 19 to rotate so that the two carrying plates 16 are separated from each other, so that multiple steel plates can fall into the collection container uniformly and be transported to the next process with the collection container. However, since the bottom of the steel plate is supported by the carrying plate 16, when the carrying plate 16 is away from the steel plate, the steel plate may deviate or fall due to friction, thereby causing When the steel plates are in the collection container, they are relatively messy, which affects the subsequent transportation efficiency. Therefore, in order to avoid this situation, when the two carrying plates 16 move away from each other, the electric push rod three 41 will also drive the connecting plate 37 to move, and the connecting plate 37 will slide on the sliding rod six 38. The connecting plate 37 will drive the sliding rod seven 42 and the stabilizing plate 17 to move and approach the steel plates. The steel plates can be clamped by the stabilizing plates 17 on both sides, and the collection container is placed under the steel plates and contacts with the bottom of the steel plates. Even if the steel plates are separated from the carrying plates 16 at this time, the steel plates will remain neat under the action of the two stabilizing plates 17 and will not deviate or tip over. Then the stabilizing plate 17 will move away from the steel plates again, so that multiple steel plates can be neatly placed in the collection container in an upright state, avoiding the situation where the transportation efficiency is affected by the mess of the steel plates.

[0056] Moreover, although a plurality of steel plates can be neatly placed in a collection container in an upright state, if the collection container is subjected to external force during transportation, the upright steel plates are still easy to fall over, and the falling direction may not be uniform, which will still cause the steel plates to be messy and affect the transportation efficiency. Therefore, in order to avoid this situation, after the steel plates are clamped by the two stabilizing plates 17, the motor 2 18 is used to drive the threaded rod 2 15 to rotate, so that the threaded plate 20 moves horizontally, and the electric push rod 1 21 drives the push block 23 to descend, so that the push block 23 contacts the steel plate on either the leftmost or rightmost side, and then drives the push block 23 to move horizontally, so that the push block 23 can be used to The upright steel plates are pushed, and since the stabilizing plate 17 elastically clamps the steel plates, multiple steel plates will tilt in one direction after being subjected to external force. While tilting, the two sides of the steel plates are limited by the stabilizing plate 17. Therefore, multiple steel plates will be arranged in an inclined state in the collection container. Although the steel plates tilt, the adjacent steel plates are in contact, and the tilting angle and direction are uniform. This method can ensure the neatness of the steel plates, and will not cause the tilting directions of multiple upright steel plates to be inconsistent due to the external force on the collection container, resulting in messy steel plates. This further ensures the neatness of the steel plates and is conducive to transportation.

[0057] Working principle: The cold-rolled steel plate to be measured for thickness is placed on the conveyor belt 3, and the ultrasonic probe 43 is above the cold-rolled steel plate. Then, the motor 44 is used to drive the threaded rod 27 to rotate, so that the lifting plate 40 drives the ultrasonic probe 43 to contact the cold-rolled steel plate. The ultrasonic probe 43 transmits ultrasonic pulses that propagate inside the cold-rolled steel plate to be measured. When it encounters the bottom surface of the cold-rolled steel plate, it is reflected. The reflected wave is received and its propagation time is calculated to obtain the thickness of the steel plate. The above-mentioned thickness measuring device 4 and measurement method are prior art and will not be described in detail. The process of manually holding the ultrasonic probe 43 in contact with the cold-rolled steel plate for measurement is eliminated, which is more convenient. After the thickness of a steel plate is measured, the thickness data of the steel plate will be displayed on the display screen of the thickness measuring device 4. The conveyor belt 3 drives the steel plate to move, and the motor 30 drives the bidirectional threaded rod 29 to rotate, so that the two clamps 28 approach each other, and the clamps 28 clamp the steel plate. If the thickness of the steel plate is unqualified, the motor 8 45 drives the threaded rod 3 24 to rotate, so that the slide plate 5 moves away from the bearing plate 16, and then the worker can place a tool for measuring the thickness of the steel plate at the end of the conveyor belt 3. The collection box for collecting steel plates with unqualified thickness. When the steel plate is aligned with the collection box opening, the clamping plate 28 loosens the steel plate, and the conveyor belt 3 continues to operate, so that the steel plate with unqualified thickness can fall into the collection box for collection; if the thickness of the steel plate is qualified, the clamping plate 28 drives the steel plate close to the carrying plate 16, and according to the width of the steel plate, the motor 9 46 can be used to drive the bidirectional threaded rod 19 to rotate, so that the two carrying plates 16 are close to each other, and the inner angle of the carrying plate 16 is aligned with the edge of the steel plate. At this time, the steel plate can move between the two carrying plates 16 along the conveyor belt 3. , and because the carrying plate 16 is in an inclined state, the steel plate will slide down to the end of the carrying plate 16 under the action of gravity, and then repeat the above operation, and the steel plates with qualified thickness will be arranged in sequence and placed between the two carrying plates 16, thereby realizing the separation of steel plates with qualified thickness and steel plates with unqualified thickness, avoiding the situation where steel plates with unqualified thickness are put into subsequent processing and production together with steel plates with qualified thickness, ensuring the processing quality of the steel plates, and also eliminating the process of workers manually separating steel plates with qualified thickness and steel plates with unqualified thickness, saving manpower;The second step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate. At the same time, the third step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate. At the same time, the third step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate. At the same time, the third step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate. At the same time, the third step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate. At the same time, the third step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate. At the same time, the third step is to rotate the slider 35 so that the slider 35 can move on the adjusting rod 11 and align the slider 36 with the steel plate.

[0058] When a sufficient number of steel plates are collected on the carrying plate 16 and the steel plates on the carrying plate 16 need to be collected, the motor 12 can be used to drive the threaded rod 9 to rotate, so that the adjusting rod 11 is moved away from under the carrying plate 16. At this time, the worker can place the collection container or the transport trolley under the carrying plate 16, and drive the chute plate 8 to rotate by the extension and contraction of the hydraulic cylinder 10, so that the carrying plate 16 is horizontal. Then, the motor 946 is used to drive the two-way threaded rod 19 to rotate, so that the two carrying plates 16 are separated from each other, so that multiple steel plates can fall into the collection container uniformly and be transported to the next process with the collection container. However, since the bottom of the steel plate is supported by the carrying plate 16, the carrying plate 1 When the two carrying plates 16 are away from each other, the steel plates may deviate or fall over due to friction, which may cause the steel plates to be messy in the collection container and affect the subsequent transportation efficiency. Therefore, in order to avoid this situation, when the two carrying plates 16 are away from each other, the electric push rod 31 will also drive the connecting plate 37 to move, and the connecting plate 37 will slide on the sliding rod 6 38. The connecting plate 37 will drive the sliding rod 7 42 and the stabilizing plate 17 to move and approach the steel plate, so that the steel plate can be clamped by the stabilizing plates 17 on both sides, and the collection container is placed under the steel plate and contacts with the bottom of the steel plate. Even if the steel plate is separated from the carrying plate 16 at this time, the steel plate will remain neat under the action of the two stabilizing plates 17 and will not deviate or fall over. After the stabilizing plate 17 is further away from the steel plate, multiple steel plates can be neatly placed in the collection container in an upright state, avoiding the situation where the steel plates are messy and affect the transportation efficiency; and although multiple steel plates can be neatly placed in the collection container in an upright state, if the collection container is subjected to external force during transportation, the upright steel plates are still easy to fall over, and the falling direction may not be uniform, which will still cause the steel plates to be messy and affect the transportation efficiency. Therefore, in order to avoid this situation, when the steel plate is clamped by the two stabilizing plates 17, the motor 2 18 is used to drive the threaded rod 2 15 to rotate, so that the threaded plate 20 moves horizontally, and the electric push rod 1 21 drives the push block 23 to descend, so that the push block 23 is aligned with either the leftmost or rightmost side. The steel plates on the side are in contact, and then the push block 23 is driven to move horizontally, and the push block 23 can be used to push the erected steel plates, and because the stabilizing plate 17 elastically clamps the steel plates, multiple steel plates will be uniformly tilted in one direction after being subjected to external force. At the same time, the two sides of the steel plates are limited by the stabilizing plate 17, so multiple steel plates will be arranged in an inclined state in the collection container. Although the steel plates tilt, the adjacent steel plates are in contact, and the tilting angle and direction are uniform. This method can ensure the neatness of the steel plates, and will not cause the tilting directions of multiple erected steel plates to be inconsistent due to the external force on the collection container, resulting in a messy steel plate situation, further ensuring the neatness of the steel plates and facilitating transportation.
