Description

Technical Field

[0001] This utility model relates to the field of cold-rolled strip steel production technology, and more specifically, to a cold-rolled strip steel thickness detection device. Background Technology

[0002] Cold-rolled strip steel is made from hot-rolled strip steel, which is pickled to remove oxide scale and then cold-rolled continuously. The finished product is a hard-rolled coil. Due to work hardening caused by continuous cold deformation, the strength and hardness of the hard-rolled coil increase, while its toughness and plasticity decrease, thus deteriorating its stamping performance. It is often used for parts with simple deformation. Thickness control of cold-rolled strip steel is a key technology in the field of plate rolling. Thickness is an important control indicator in the production of cold-rolled strip steel. To ensure the production quality of cold-rolled strip steel, it is necessary to detect the thickness of cold-rolled strip steel on the production line to reject unqualified cold-rolled strip steel with excessive thickness fluctuations. During use, existing cold-rolled strip steel thickness detection devices, due to their own structural limitations, can mostly only perform single-point thickness detection, resulting in a relatively limited detection area and affecting the detection effect of cold-rolled strip steel thickness. Based on this, this utility model designs a cold-rolled strip steel thickness detection device to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a cold-rolled strip thickness detection device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A device for detecting the thickness of cold-rolled strip steel includes a detection platform, a first laser thickness gauge, a second laser thickness gauge, and a transmission block. The first and second laser thickness gauges are arranged in a staggered manner on both sides. An electric push rod is fixedly installed on the detection platform, and the transmission block is fixedly installed on the telescopic end of the electric push rod. Guide roller assemblies are provided at both ends of the detection platform. A carrier is fixedly installed at the bottom of both the first and second laser thickness gauges. The carrier is rotatably connected to the detection platform via a vertical shaft. A sector gear is fixedly sleeved on the outside of the vertical shaft. A front gear seat is fixedly installed on one front end of the transmission block, and a rear gear seat is fixedly installed on the other rear end of the transmission block. The two sector gears mesh with the front gear seat and the rear gear seat, respectively.

[0006] As a preferred embodiment of the present invention, the guide roller assembly includes a guide frame and a supporting guide roller. The guide frame is fixedly installed on the testing platform, and the supporting guide roller is rotatably connected to the top side of the guide frame via a rotating shaft.

[0007] As a preferred embodiment of this utility model, the testing platform is fixedly mounted with a guide rod via a side block, and a limiting groove is formed on the end face of the transmission block, the limiting groove being slidably sleeved on the outside of the guide rod.

[0008] In a preferred embodiment of this utility model, there are two guide rods, which are symmetrically distributed.

[0009] As a preferred embodiment of this utility model, a controller is fixedly installed on the testing platform, and an indicator light is fixedly installed on the top of the controller. The output terminals of the first laser thickness gauge and the second laser thickness gauge are electrically connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the input terminal of the indicator light.

[0010] As a preferred embodiment of this utility model, a display screen is fixedly mounted on the controller, and the output terminal of the controller is electrically connected to the input terminal of the display screen.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model involves passing the cold-rolled strip steel of the production line through a first laser thickness gauge and a second laser thickness gauge. The support guide rollers provide good guidance and support for the cold-rolled strip steel. The electric push rod repeatedly extends and retracts to drive the transmission block to move back and forth. Two sector gears mesh with the front and rear gear seats respectively, thereby driving the first and second laser thickness gauges to rotate and reciprocate along both sides of the cold-rolled strip steel in an arc. This facilitates multi-point thickness detection of the cold-rolled strip steel, effectively expanding the detection area and ensuring the thickness detection effect of the cold-rolled strip steel.

[0013] 2. This utility model, by setting a limiting groove and a guide rod, with the limiting groove slidably sleeved on the outside of the guide rod and the two guide rods symmetrically distributed, utilizes the cooperation between the guide rod and the limiting groove to help ensure the stability of the transmission block when moving back and forth.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 4 As shown, this utility model provides a cold-rolled strip thickness detection device, including a detection table 1, a first laser thickness gauge 2, a second laser thickness gauge 3, and a transmission block 5. The first laser thickness gauge 2 and the second laser thickness gauge 3 are arranged in a staggered manner on both sides. An electric push rod 4 is fixedly installed on the detection table 1, and the transmission block 5 is fixedly installed on the telescopic end of the electric push rod 4. Guide roller assemblies 7 are provided at both ends of the detection table 1. A carrier 6 is fixedly installed at the bottom end of both the first laser thickness gauge 2 and the second laser thickness gauge 3. The carrier 6 is connected by a vertical shaft 601. Rotatably connected to the testing table 1, the external sleeve of the vertical shaft 601 is fitted with a sector gear 602. A front gear seat 501 is fixedly installed on one front end of the transmission block 5, and a rear gear seat 502 is fixedly installed on the other rear end of the transmission block 5. The transmission block 5 is driven to move back and forth by the repeated extension and retraction of the electric push rod 4. The two sector gears 602 mesh with the front gear seat 501 and the rear gear seat 502 respectively, thereby driving the first laser thickness gauge 2 and the second laser thickness gauge 3 to rotate and reciprocate along the two sides of the cold-rolled strip steel 9 in an arc.

[0021] Among them, such as Figure 2 As shown, the guide roller assembly 7 includes a guide frame 701 and a support guide roller 702. The guide frame 701 is fixedly installed on the inspection table 1, and the support guide roller 702 is rotatably connected to the top side of the guide frame 701 through a rotating shaft 703. The support guide roller 702 can provide good guidance and support for the cold-rolled strip steel 9.

[0022] Among them, such as Figure 3 and Figure 4As shown, the test platform 1 is fixedly installed with a guide rod 102 via a side block 101. A limiting groove 503 is provided on the end face of the transmission block 5. The limiting groove 503 is slidably sleeved on the outside of the guide rod 102. There are two guide rods 102, which are symmetrically distributed. The cooperation between the guide rods 102 and the limiting groove 503 helps to ensure the stability of the transmission block 5 when it moves back and forth.

[0023] Among them, such as Figure 3 As shown, a controller 8 is fixedly installed on the testing table 1. An indicator light 801 is fixedly installed on the top of the controller 8. The output terminals of the first laser thickness gauge 2 and the second laser thickness gauge 3 are electrically connected to the input terminal of the controller 8, and the output terminal of the controller 8 is electrically connected to the input terminal of the indicator light 801. The first laser thickness gauge 2 and the second laser thickness gauge 3 can transmit the detected thickness information to the controller 8. If the detected thickness information exceeds the preset value range, the controller 8 will control the indicator light 801 to light up to issue an abnormal thickness warning signal for the cold-rolled strip steel 9.

[0024] Among them, such as Figure 3 As shown, a display screen 802 is fixedly installed on the controller 8. The output terminal of the controller 8 is electrically connected to the input terminal of the display screen 802. The detected thickness information can be displayed and processed using the display screen 802.

[0025] The working principle of this utility model:

[0026] During the use of this cold-rolled strip thickness detection device, the cold-rolled strip 9 from the production line passes through the first laser thickness gauge 2 and the second laser thickness gauge 3. The support guide roller 702 provides good guidance and support for the cold-rolled strip 9. The electric push rod 4 repeatedly extends and retracts to drive the transmission block 5 to move back and forth. The two sector gears 602 mesh with the front gear seat 501 and the rear gear seat 502 respectively, thereby driving the first laser thickness gauge 2 and the second laser thickness gauge 3 to rotate and reciprocate along the two sides of the cold-rolled strip 9 in an arc. This facilitates multi-point thickness detection of the cold-rolled strip 9, effectively expanding the detection area. If the detected thickness information exceeds the preset value range, the controller 8 controls the indicator light 801 to light up to issue an abnormal thickness warning signal for the cold-rolled strip 9. The detected thickness information can be viewed intuitively through the display screen 802.
