Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, and in particular to a clamping device for metal sheets. Background Technology

[0002] With the development of society, the demand for metal is increasing. Metal sheets are used to make the products needed, and cutting is required during the processing. In the cutting process of metal sheets, clamps are an indispensable device. Clamps are used to fix the sheet on the top of the worktable, so that it is convenient to cut it with the cutting device, ensuring that the sheet does not shift during the cutting process and improving the stability of the cutting.

[0003] The existing Chinese patent publication number CN217860149U discloses a two-sided stabilizing clamping device for cutting metal sheets. According to its description, the device mainly clamps the metal sheet by unfolding hinge rods on both sides to drive the pressure plate. The clamping components of this structure are relatively large. After clamping the metal sheet, the large protruding structure can easily affect the operator's subsequent cutting operation, thereby reducing the user experience of the device.

[0004] Therefore, it is necessary to provide a new clamping device for metal sheets to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a clamping device for metal sheets.

[0006] The metal sheet clamping device provided by this utility model includes: a frame, wherein clamping components are movably connected on both sides of the frame body;

[0007] The clamping assembly includes a sliding frame that is slidably inserted into the frame body. A clamping frame that is slidably connected is inserted into the inner top of the sliding frame. A pressure sensor is provided in the inner top of the sliding frame, and the position of the pressure sensor is opposite to the position of the clamping frame.

[0008] Preferably, the frame body has several sliding grooves inside, and the inner wall of the sliding groove abuts against and is slidably connected to the outer wall of the support rod in the sliding frame.

[0009] Preferably, the sliding frame has a through groove inside, and the opposite surfaces of the two sides of the sliding frame are provided with a linkage plate that is movably connected, and the side wall of the linkage plate is provided with a rod.

[0010] Preferably, the outer wall of the insertion rod abuts against and slides against the inner wall of the through groove, and a threaded limiting cap is fitted on the outer wall of the insertion rod, and the end of the limiting cap abuts against and slides against the outer wall of the support rod in the sliding frame.

[0011] Preferably, the bottom of the linkage plate is provided with a transition plate, the outer wall of the transition plate abuts against and slides with the inner wall of the corresponding slide groove, the bottom of the transition plate is provided with a cylinder, and the bottom end of the cylinder is fixedly connected to the sliding frame.

[0012] Preferably, a rotating rod is rotatably connected to the inner top of the frame, one end of the rotating rod is provided with a drive motor, and the drive motor is connected to the inner top of the frame.

[0013] Preferably, both sides of the outer wall of the rotating rod are threaded to the inner wall of the adapter plate through a threaded structure, and the thread directions of the threaded structures on both sides are opposite.

[0014] Compared with related technologies, the metal sheet clamping device provided by this utility model has the following advantages:

[0015] 1. The clamping component of this utility model is vertically installed inside the frame body. Its structure is compact. In the later use, it can reduce the outward convex area of ​​the clamping structure, thereby reducing the impact of the protruding clamping parts on the cutting operation of the workers during use. Therefore, it can improve the flexibility of the device to a certain extent.

[0016] 2. By incorporating a pressure sensor into the clamping assembly, the controller at the terminal can accurately control the clamping force of the metal plate during the clamping process by monitoring the pressure sensor readings, thereby reducing the impact caused by insufficient or excessive clamping force.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 4 The present invention provides a clamping device for metal plates, which includes a frame 1.

[0025] In the embodiments of this utility model, please refer to Figures 1 to 4 The frame 1 has two movable clamping components 2 on both sides inside; the clamping components 2 include a sliding frame 21, which is slidably inserted into the frame 1. A clamping frame 22 is slidably connected to the top of the sliding frame 21. A pressure sensor 212 is provided on the top of the sliding frame 21, and the position of the pressure sensor 212 is opposite to the position of the clamping frame 22.

[0026] It should be noted that: since the clamping component 2 in this device is vertically installed inside the frame 1, its structure is compact. In later use, the outward protrusion area of ​​the clamping structure can be reduced, thereby reducing the impact of the protruding clamping components on the cutting operation of the workers. Therefore, it can improve the flexibility of the device to a certain extent. In the process of clamping the metal plate, the terminal controller (the controller can be an existing PLC controller, microcontroller controller, etc.) can accurately control the clamping force on the metal plate by monitoring the value of the pressure sensor 212, thereby reducing the impact caused by insufficient or excessive clamping force.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 4 The frame 1 has several sliding grooves 11 inside, and the inner wall of the sliding groove 11 abuts against and slides with the outer wall of the support rod in the sliding frame 21. The sliding frame 21 has a through groove 211 inside. The opposing surfaces of the two sliding frames 21 are provided with a movable linkage plate 3, and the side wall of the linkage plate 3 is provided with a rod 33. The outer wall of the rod 33 abuts against and slides with the inner wall of the through groove 211. The outer wall of the rod 33 is fitted with a threaded limit cap 34, and the end of the limit cap 34 abuts against and slides with the outer wall of the support rod in the sliding frame 21. The bottom of the linkage plate 3 is provided with a transition plate 31. The outer wall of the transition plate 31 abuts against and slides with the inner wall of the corresponding sliding groove 11. The bottom of the transition plate 31 is provided with a cylinder 32, and the bottom end of the cylinder 32 is fixedly connected to the sliding frame 21.

[0028] It should be noted that by sliding the sliding frame 21 and the slide groove 11, the sliding frame 21 can be flexibly controlled to move inside the frame 1 during later use, thereby adjusting the position of the internal clamping frame 22. Since the linkage plate 3 is movably mounted on the sliding frame 21, when the cylinder 32 is working, it can drive the sliding frame 21 to move downward inside the frame 1. Since the linkage plate 3 is movably mounted on the sliding frame 21 through the insert rod 33, the obstruction to the movement of the sliding frame 21 can be reduced. Therefore, the internal clamping frame 22 can be moved downward by driving the sliding frame 21 to clamp the metal plate.

[0029] In the embodiments of this utility model, please refer to Figures 1 to 4 The inner top of the frame 1 is equipped with a rotating rod 4 that is rotatably connected. One end of the rotating rod 4 is equipped with a drive motor 41, and the drive motor 41 is connected to the inner top of the frame 1. Both sides of the outer wall of the rotating rod 4 are threaded to the inner wall of the adapter plate 31 through a threaded structure, and the thread directions of the threaded structures on both sides are opposite.

[0030] It should be noted that by using a threaded structure with opposite thread directions on both sides of the outer wall of the rotating rod 4 to connect with the adapter plate 31, when the drive motor 41 drives the rotating rod 4 to rotate, the adapter plates 31 on both sides can move relative to each other or in opposite directions. The movement of the adapter plates 31 can drive the linkage plate 3 to move synchronously, thereby achieving the initial positioning of the metal plate placed on the frame 1. Therefore, it is convenient for the clamping assembly 2 to clamp and fix the metal plate later.

[0031] The working principle of the metal sheet clamping device provided by this utility model is as follows;

[0032] During the use of this device, the operator can first place the metal sheet to be processed on the frame 1, and then control the drive motor 41 to drive the rotating rod 4 to rotate. The rotating rod 4 will drive the adapter plate 31 to move relative to each other through the thread structure with opposite threads on both sides of the outer wall. During the movement, the adapter plate 31 will drive the sliding frame 21 and its components to move synchronously through the linkage plate 3 until the outer wall of the linkage plate 3 abuts against the side wall of the metal sheet, thus completing the initial positioning of the metal sheet.

[0033] Next, the controllable cylinder 32 can extend. The extended cylinder 32 will drive the sliding frame 21 to slide downward inside the frame 1. During this process, when the bottom of the clamping frame 22 in the sliding frame 21 abuts against the top of the metal plate, the abutting force will cause the clamping frame 22 to slide upward until the top of the clamping frame 22 abuts against the pressure sensor 212, which will continuously clamp the metal plate. At the same time, the operator can monitor the value of the pressure sensor 212 through the terminal controller to control the clamping force on the metal plate. Therefore, the unnecessary impact caused by the clamping force of the clamping frame 22 on the metal plate being too small or too large during use can be reduced.

[0034] Since the clamping component 2 is movably installed inside the frame 1, its overall structure is relatively compact. Therefore, the impact of the protruding clamping parts on the cutting operator's operation after clamping the metal plate can be reduced, thereby improving the user experience of this device.

[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0036] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
