Description

Technical Field

[0001] The utility model belongs to the technical field of CMT welding, and specifically relates to a CMT tooling fixture for reinforcing beams. Background Art

[0002] The CMT tooling for reinforcing beams is not a single tool, but an integrated and automated manufacturing system. It combines a welding robot centered on CMT (Cold Metal Transfer) technology with dedicated fixtures, positioners, control systems and the like, to form an efficient workstation specially used for welding reinforcing plates (rib plates, stiffeners) on various types of steel beams (such as H-beams, I-beams, box beams), so as to solve the inherent problems of large deformation, unstable quality, low efficiency and other difficulties in traditional beam reinforcement welding.

[0003] However, the existing CMT tooling fixtures still have the following defects in the use process, for example: 1. There are errors in the process of assembling and clamping the workpiece, which affects the welding quality; 2. A set of tooling is usually designed for processing beams with specific cross-sections and lengths. When the product model changes, especially when the cross-sectional dimension of the beam or the layout of the reinforcing plate changes greatly, the fixture may need to be replaced or adjusted, which is high in cost and will affect the production efficiency. Therefore, it is urgent to design a CMT tooling fixture for reinforcing beams to solve the above problems. Contents of the Utility Model

[0004] The purpose of the utility model is to provide a CMT tooling fixture for reinforcing beams, so as to solve the problems existing in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A CMT tooling fixture for reinforcing beams, comprising: a base, wherein the base comprises a bottom plate, support legs fixed at four corners of the bottom of the bottom plate, and lifting rings fixed at four corners of the top of the bottom plate, and the bottom plate is provided with a plurality of reserved openings; a positioning mechanism, wherein the positioning mechanism comprises limit plates fixedly connected to two adjacent sides of the top of the bottom plate and side push plates movably arranged on the other two adjacent sides of the top of the bottom plate, one side of each side push plate is provided with a positioning cylinder, one side of the top of the bottom plate is fixedly connected with a quick-change pressure plate, and two sides of the top of the bottom plate are provided with corresponding laser sensors; a clamping mechanism, wherein the clamping mechanism comprises a plurality of clamping cylinders, the plurality of clamping cylinders are arranged on the top of the bottom plate in a shape of the Chinese character "ri" and are fixedly connected with the bottom plate through angle seats, the top of each clamping cylinder is provided with an adapter block, the adapter block is movably connected with a pressure arm through a rotating shaft, the clamping cylinder is movably connected with one end of the pressure arm, the other end of the pressure arm is fixed with a clamping block, and a proximity sensor is fixed on the clamping block.

[0006] Furthermore, connecting blocks are fixed around the base plate by bolts, and the connecting blocks are provided with positioning holes for positioning and connection with external equipment.

[0007] Furthermore, an electrical box and a solenoid valve box are fixedly connected to the bottom of the base plate. Both the electrical box and the solenoid valve box adopt a modular design. The electrical box is equipped with a power module, a control module for receiving external commands, and a signal processing module for controlling the action of the clamping cylinder and the positioning cylinder. The solenoid valve box is equipped with multiple solenoid valves for controlling the air intake and exhaust of the cylinder.

[0008] Furthermore, a limiting block is provided at the bottom of one end of the pressure arm, and a handle is fixed at the top of the other end, with a ball head fixed at the top of the handle.

[0009] Furthermore, the solenoid valve box, positioning cylinder, laser sensor, clamping cylinder, and proximity sensor are all electrically connected to the electrical box.

[0010] Furthermore, the quick-change pressure plate is provided with a slot structure for quickly changing pressure plates of different specifications, and the bottom of the quick-change pressure plate is securely connected to the base plate by bolts.

[0011] Furthermore, the lower surface of the clamping block is provided with anti-slip texture to increase the friction when in contact with the reinforcing beam.

[0012] Furthermore, the support legs are designed to be height-adjustable, with each support leg equipped with an adjusting screw and a locking nut.

[0013] The technical effects and advantages of the present utility model are as follows: the CMT tooling fixture for reinforcing beams features advanced design, compact structure and convenient use. Through the mutual cooperation of the limit plate and the side push plate in the positioning mechanism, the reinforcing beam can be accurately positioned. The laser sensor can monitor the position information of the reinforcing beam in real time to ensure the positioning accuracy, effectively avoiding the problem that the welding quality is affected by errors during the assembly and clamping process of the workpiece, and greatly improving the welding quality. At the same time, the slot structure on the quick-change pressure plate makes it fast and convenient to replace pressure plates of different specifications. When the product model is changed, and the section size of the beam or the layout of the reinforcing plate is changed, there is no need to replace the entire fixture, and only the appropriate pressure plate needs to be replaced, which reduces the cost and does not affect the production efficiency. The clamping cylinders arranged in a shape of the Chinese character "Ri" in the clamping mechanism can provide stable and uniform clamping force for the reinforcing beam, ensuring that the reinforcing beam will not move during the welding process. Moreover, the anti-slip texture on the lower surface of the clamping block further increases the friction force when contacting with the reinforcing beam, further ensuring the clamping stability. In addition, the height-adjustable design of the support legs enables the fixture to adapt to working scenarios of different heights, enhancing its versatility and practicability. The modular design of the electrical box and the solenoid valve box facilitates the maintenance and management of the equipment, and each module has a clear division of labor, ensuring the efficient operation of the entire fixture.

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.

[0017] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] This utility model provides, for example Figure 1-4 The CMT tooling fixture shown includes: The base 100 includes a base plate 101, support legs 102 fixed at the four corners of the bottom of the base plate 101, and lifting rings 103 fixed at the four corners of the top of the base plate 101. The base plate 101 is provided with several reserved openings 104. The entire fixture can be easily lifted and installed through the lifting rings 103. The reserved openings 104 provide installation space for components or wiring that may be added later. The positioning mechanism 200 comprises limit plates 201 fixedly connected to two adjacent sides of the top of the base plate 101 and side push plates 202 movably arranged on the other two adjacent sides of the top of the base plate 101. A positioning cylinder 203 is provided on one side of the side push plate 202, a quick-change pressure plate 204 is fixedly connected to one side of the top of the base plate 101, and corresponding laser sensors 205 are arranged on both sides of the top of the base plate 101. In actual operation, the positioning cylinder 203 pushes the side push plate 202 to move, and cooperates with the limit plates 201 to accurately position the reinforcing beam at a designated position. The laser sensors 205 monitor the position information of the reinforcing beam in real time and feed the data back to the control module in the electrical box 106 to ensure positioning accuracy; The clamping mechanism 300 comprises a plurality of clamping cylinders 301. The plurality of clamping cylinders 301 are arranged on the top of the base plate 101 in a shape of the Chinese character "ri", and are fixedly connected to the base plate 101 through angle seats 302. An adapter block 303 is provided at the top of the clamping cylinder 301, a pressure arm 304 is movably connected to the adapter block 303 through a rotating shaft, the clamping cylinder 301 is movably connected to one end of the pressure arm 304, a clamping block 305 is fixed at the other end of the pressure arm 304, and a proximity sensor 306 is fixed on the clamping block 305. When the positioning of the reinforcing beam is completed, the clamping cylinder 301 is activated to push the pressure arm 304 to rotate around the rotating shaft, so that the clamping block 305 moves downward and presses the reinforcing beam. The proximity sensor 306 monitors the distance between the clamping block 305 and the reinforcing beam in real time to ensure that the clamping force is moderate, which will neither cause the reinforcing beam to move during the welding process due to too small clamping force, nor damage the reinforcing beam due to too large clamping force.

[0020] For example, refer to Figures 1-3 as shown, connecting blocks 105 are fixed around the base plate 101 by bolts, and the connecting blocks 105 are provided with positioning holes for positioning and connecting with external equipment.

[0021] In this technical solution, through the positioning holes, the fixture can be conveniently positioned and connected with external equipment (such as welding robots, positioners, etc.) to form a complete welding workstation.

[0022] For example, refer to Figure 3 as shown, an electrical box 106 and a solenoid valve box 107 are fixedly connected to the bottom of the base plate 101. Both the electrical box 106 and the solenoid valve box 107 adopt a modular design. The electrical box 106 is internally provided with a power module, a control module for receiving external instructions, and a signal processing module for controlling the actions of the clamping cylinders 301 and the positioning cylinders 203. A plurality of solenoid valves for controlling the inlet and outlet of air to the cylinders are installed in the solenoid valve box 107.

[0023] In this technical solution, the modular design makes the maintenance and management of the electrical box 106 and the solenoid valve box 107 more convenient. When a module fails, it can be quickly replaced, reducing downtime and improving production efficiency.

[0024] For example, see Figure 1 and Figure 4 As shown, a limiting block 307 is provided at the bottom of one end of the pressure arm 304, and a handle 308 is fixed at the top of the other end, with a ball head 309 fixed at the top of the handle 308.

[0025] In this technical solution, the limiting block 307 is used to limit the rotation range of the pressure arm 304 and prevent the clamping block 305 from pressing down too much and damaging the reinforcing beam. The design of the handle 308 and the ball head 309 makes it convenient for the operator to manually adjust the position of the pressure arm 304 when needed.

[0026] For example, the solenoid valve box 107, the positioning cylinder 203, the laser sensor 205, the clamping cylinder 301, and the proximity sensor 306 are all electrically connected to the electrical box 106.

[0027] In this technical solution, through electrical connection, the various components can work together under the unified command of the control module of the electrical box 106 to achieve automated operation.

[0028] For example, see Figures 1-2 As shown, the quick-change pressure plate 204 is provided with a slot structure for quickly changing pressure plates of different specifications, and the bottom of the quick-change pressure plate 204 is securely connected to the base plate 101 by bolts.

[0029] In this technical solution, when the product model changes, or the cross-sectional dimensions of the beam or the layout of the reinforcing plate changes, it is not necessary to replace the entire fixture. Only the appropriate pressure plate needs to be replaced according to the new specifications, which greatly reduces costs and does not affect production efficiency.

[0030] For example, see Figure 4 As shown, the lower surface of the clamping block 305 is provided with anti-slip texture to increase the friction when in contact with the reinforcing beam.

[0031] In this technical solution, the anti-slip texture can effectively prevent the reinforcing beam from moving due to vibration during the welding process, further ensuring the welding quality.

[0032] For example, see Figures 1-3 As shown, the support leg 102 adopts an adjustable height design, and each support leg 102 is equipped with an adjusting screw and a locking nut.

[0033] In this technical solution, the height of the fixture can be adjusted according to different working scenarios by adjusting the screw and locking nut, thus enhancing its versatility and practicality.

[0034] Working principle: When using this CMT tooling fixture for reinforcing beams, the entire fixture is first lifted to a suitable working position using the lifting ring 103. It is then positioned and connected to external equipment (such as a welding robot or positioner) using the positioning holes on the connecting block 105, forming a complete welding workstation. Next, according to the specifications of the reinforcing beam, a suitable pressure plate is selected and installed in the slot structure of the quick-change pressure plate 204, ensuring that the contact surface between the pressure plate and the reinforcing beam is flat and stable. Then, the reinforcing beam is placed on the base plate 101, and the positioning cylinder 203 is activated. The positioning cylinder 203 pushes the side push plate 202 to move, engaging with the limit plate 201. In conjunction with the control module in the electrical box 106, the reinforcing beam is precisely positioned at the designated location. At this time, the laser sensor 205 monitors the position of the reinforcing beam in real time and feeds the data back to the control module, ensuring accurate positioning. After positioning, the clamping cylinder 301 is activated, pushing the pressure arm 304 to rotate around the pivot, causing the clamping block 305 to move downwards and press against the reinforcing beam. The proximity sensor 306 monitors the distance between the clamping block 305 and the reinforcing beam in real time and feeds the data back to the control module, ensuring appropriate clamping force. During welding, the anti-slip texture effectively prevents the reinforcing beam from moving due to vibration, ensuring welding quality. Simultaneously, the various modules in the electrical box 106 and the solenoid valve box 107 work together to ensure the efficient operation of the entire fixture. When the product model changes, or the beam's cross-sectional dimensions or the reinforcing plate layout changes, only the appropriate pressure plate needs to be replaced according to the new specifications; the entire fixture does not need to be replaced, significantly reducing costs and not affecting production efficiency. In addition, by adjusting the adjusting screw and locking nut on the support leg 102, the height of the clamp can be adjusted according to different working scenarios, enhancing its versatility and practicality.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
