Description

Technical Field

[0001] This utility model relates to the field of plate rolling machine technology, and in particular to a plate bending detection device for an upper roller universal plate rolling machine. Background Technology

[0002] The upper roller universal plate rolling machine is a common metal sheet processing equipment, mainly used for rolling and bending metal sheets. In order to ensure the quality of the sheet during processing, especially during bending and forming, the bending condition of the sheet must be monitored and adjusted in real time. Traditional bending detection mainly relies on manual measurement and inspection, or on simple sensors to detect the surface deformation of the sheet, which has certain limitations. It cannot provide accurate bending data or detailed bending shape, and it is also difficult to ensure uniform quality control of different batches or different materials of sheet. It is difficult to monitor the degree of bending of the sheet in real time and accurately, and it cannot meet the high precision requirements of complex processes.

[0003] A protective device for an upper roller universal plate rolling machine, disclosed in announcement number CN111774451A, includes a protective structure mounted on a tilting cylinder and fixed to a tilting plate, and a limiting mechanism mounted on a base and located below the plate rolling mechanism. This protective device, through a self-cleaning component, removes accumulated dust or solidified lubricating oil from the surface of the horizontal shaft, preventing increased resistance between the shaft head and the horizontal shaft. Through a safety component, when the shaft head is jammed against the horizontal shaft and the piston rod of the tilting cylinder reaches a certain threshold force, the piston rod disengages from the shaft head, preventing bending. Through the limiting mechanism, the distance between the two guiding components can be adjusted according to the size of the plate during feeding or processing, increasing the range of processable plate sizes. It can also be retracted after processing without affecting the removal of the finished plate.

[0004] However, the protection device of this universal plate rolling machine has the following disadvantages: traditional bending detection mainly relies on manual measurement and inspection, or on simple sensors to detect the surface deformation of the plate, which has certain limitations. It cannot provide accurate bending data and detailed bending morphology. For different detection needs, it is necessary to manually disassemble, reposition and install, and adjust the sensor position, which is cumbersome and time-consuming. Utility Model Content

It cannot provide accurate bending data and detailed bending morphology. For different detection needs, it is necessary to manually disassemble, reposition and install, and adjust the sensor position, which is cumbersome and time-consuming.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a plate bending detection device for an upper roller universal plate rolling machine, comprising a plate rolling machine body, a control box fixedly connected to one side of the plate rolling machine body, a cover plate fixedly connected to the top of the control box, a drive assembly fixedly connected to the top of the cover plate, multiple sets of laser sensors fixedly connected to the middle of the drive assembly, and a fixing pin assembly inserted into one end of each laser sensor; the drive assembly includes a support plate fixedly connected to the top of the cover plate, a bidirectional threaded rod rotatably connected to the middle of the support plate, and two sets of mounting plates threadedly connected to the surface of the bidirectional threaded rod; the fixing pin assembly includes a sleeve inserted into one end of the laser sensor, a push rod slidably connected to the inner wall of the sleeve, and two sets of limiting rods rotatably connected to the surface of the push rod.

[0009] As a further embodiment of this utility model, two sets of sliding rods are fixedly connected to one side of the support plate, and a frame is fixedly connected to the other end of the sliding rods. By setting the sliding rods, the two sets of sliding rods can simultaneously ensure the stability and linear accuracy of the movement of the mounting plate, and prevent the laser sensor from shifting or shaking.

[0010] As a further embodiment of this utility model, one end of the bidirectional threaded rod is fixedly connected to a motor, and a protective shell is fitted onto the surface of the motor. The protective shell serves to protect the motor from external environmental factors, ensure the stable operation of the motor, and improve the reliability and durability of the system.

[0011] As a further embodiment of this utility model, the surface of the sleeve rod is provided with two sets of limiting grooves, and the surface of the sleeve rod is threaded with a nut. By setting the nut, the rotation of the nut can strengthen the tightness of the sleeve rod, and at the same time increase the thrust of the limiting rod, so as to fix the laser sensor to the mounting plate.

[0012] As a further embodiment of this utility model, a handle is fixedly connected to one end of the sleeve rod, and a pressing head is fixedly connected to one end of the push rod. A limit ring is fixedly connected to one side of the pressing head.

[0016] (III) Beneficial Effects

[0017] This utility model provides a plate bending detection device for an upper roller universal plate rolling machine, which has the following beneficial effects:

[0018] 1. The plate bending detection device of this universal plate rolling machine, through the setting of the drive component, when the laser sensor can adapt to the detection of plates of different sizes and specifications, starts the motor, driving the bidirectional threaded rod to achieve precise linear motion adjustment. The surface of the bidirectional threaded rod is machined with two sections of threads facing opposite directions, and two sets of mounting plates are respectively connected to these two sections of threads. Through the rotation of the threads on the surface of the bidirectional threaded rod, the two sets of mounting plates are driven to move in opposite directions in a straight line along the axial direction of the bidirectional threaded rod, realizing the forward and backward movement of the mounting plates, precisely controlling the position of the mounting plates, ensuring the linear accuracy of the movement of the mounting plates, and thus realizing the adjustment of the detection position of the laser sensor. At the same time, two sets of sliding rods ensure the smoothness and linear accuracy of the movement of the mounting plates, avoiding the laser sensor's offset or shaking. This enables the laser sensor to adapt to the detection of plates of different sizes and specifications, covering a larger detection area, ensuring the monitoring of the bending degree of the plate, obtaining more accurate bending data and detailed bending morphology, avoiding errors caused by manual operation, and improving work efficiency.

[0019] 2. The plate bending detection device of this universal plate rolling machine, through the setting of the fixing pin assembly, when it is necessary to improve the installation and disassembly efficiency of the laser sensor, fixes the laser sensor to the bottom of the mounting plate through the fixing pin assembly. First, the sleeve is inserted into the mounting hole on one side of the laser sensor and the inner wall of the mounting hole on the surface of the mounting plate in sequence. Pressing the push rod slides along the inner wall of the sleeve, thereby squeezing the spring and pulling the limit rod through the mounting hole on one side of the laser sensor and the mounting hole on the surface of the mounting plate. Releasing the push rod, the spring rebounds and resets, driving the limit rod out, while squeezing the outer wall of the mounting hole on the other side of the laser sensor. Then, the nut is rotated to strengthen the tightness of the sleeve and increase the thrust of the limit rod, so that the laser sensor is fixedly installed on the mounting plate. This effectively improves the installation and disassembly efficiency of the laser sensor, reduces labor time and maintenance costs, improves the stability and convenience of the laser sensor, and increases the efficiency of plate bending detection accuracy.

[0028] Two sets of sliding rods 7 are fixedly connected to one side of the support plate 401, and a frame 8 is fixedly connected to the other end of the sliding rods 7. The sliding rods 7 are set up to ensure the stability and linear accuracy of the movement of the mounting plate 403, and to prevent the laser sensor 5 from shifting or shaking.

The protective shell 10 protects the motor 9 from external environmental factors, ensures the stable operation of the motor 9, and improves the reliability and durability of the system.

[0030] The surface of the sleeve rod 601 is provided with two sets of limiting grooves, and the surface of the sleeve rod 601 is threaded with a nut 11. By setting the nut 11, the sleeve rod 601 is tightened by rotating the nut 11, and the thrust of the limiting rod 603 is increased, so that the laser sensor 5 is fixedly installed with the mounting plate 403.

[0031] One end of the sleeve rod 601 is fixedly connected to a handle 12, and one end of the push rod 602 is fixedly connected to a pressing head 13. A limit ring 14 is fixedly connected to one side of the pressing head 13.

[0035] In this invention, the working steps of the device are as follows:

[0036] First step: When the laser sensor 5 can adapt to the detection of plates of different sizes and specifications, start the motor 9 to drive the bidirectional threaded rod 402 to achieve precise linear motion adjustment. The surface of the bidirectional threaded rod 402 is machined with two sections of threads with opposite directions, and the two sets of mounting plates 403 are respectively connected to these two sections of threads. The rotation of the threads on the surface of the bidirectional threaded rod 402 is achieved through the rotation of the threads.

At the same time, the two sets of sliding rods 7 ensure the smoothness and linear accuracy of the movement of the mounting plates 403, preventing the laser sensor 5 from shifting or shaking.

[0038] Third step: When it is necessary to improve the installation and disassembly efficiency of laser sensor 5, the laser sensor 5 is fixedly connected to the bottom of mounting plate 403 by fixing pin assembly 6. First, insert sleeve rod 601 into the mounting hole on one side of laser sensor 5 and the inner wall of the mounting hole on the surface of mounting plate 403 in sequence. Press push rod 602 to slide along the inner wall of sleeve rod 601, thereby squeezing spring 16 and pulling limit rod 603 through the mounting hole on one side of laser sensor 5 and the mounting hole on the surface of mounting plate 403. Release push rod 602, spring 16 rebounds and resets, driving limit rod 603 out, while squeezing the outer wall of mounting hole on the other side of laser sensor 5. Then rotate nut 11 to strengthen the tightness of sleeve rod 601 and increase the thrust of limit rod 603, so that laser sensor 5 is fixedly installed with mounting plate 403.
