Description

Technical Field

[0001] This utility model relates to the field of welding fixture technology, specifically a stainless steel transmission belt electric permanent magnet welding fixture with a cooling structure. Background Technology

[0002] Stainless steel drive belts, made primarily of stainless steel, possess high strength, corrosion resistance, and high-temperature resistance (capable of withstanding environments from -200℃ to 600℃ for extended periods). Their smooth, flat surface ensures stable transmission and strong load-bearing capacity. Widely used in food processing (e.g., baking, sterilization lines), chemical production (transfer of corrosive materials), and metallurgical industries (transportation of high-temperature billets), they are less prone to wear and aging than traditional rubber or canvas drive belts. They also adapt to complex environments such as humidity and oil contamination, and are easy to clean and maintain, making them a crucial component in industrial automation transmission systems that combines durability and adaptability.

[0003] In the production and processing of stainless steel transmission belts, welding of the stainless steel belts is required. During welding, the workpieces to be welded need to be positioned to prevent displacement. Existing technology uses electro-permanent magnets to clamp and fix the workpieces. However, in practical use, it is inconvenient to adjust the position of the electro-permanent magnets, and it is not convenient for positioning and welding stainless steel belts of different sizes, thus having certain limitations. Therefore, improvements are needed. Utility Model Content

A support seat is rotatably sleeved on the outer side of the positive and negative screws, and the support seat is fixedly connected to the worktable. This adjustment mechanism facilitates the adjustment of the slide block's horizontal position.

[0007] Preferably, a rotating seat is rotatably sleeved on the outer side of the positive and negative screws, and the rotating seat is fixedly connected to the worktable. By designing the rotating seat, the positive and negative screws can be rotatably supported.

[0008] Preferably, both ends of the guide rod are fixedly connected to fixing blocks, and the fixing blocks are fixedly connected to the worktable. By designing the fixing blocks, the guide rod can be supported.

[0009] Preferably, the locking mechanism includes a slot, with a slot formed inside the screw. A retaining ball is movably fitted inside the slot and is movably connected to a support base. A slider is movably fitted outside the retaining ball and is slidably connected to the support base. A fixing rod is slidably fitted inside the slider and is fixedly connected to the support base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model utilizes the design of an electro-permanent magnet. When a forward current passes through, the magnetic suction block moves downward under the influence of magnetic force, thus pressing and fixing the stainless steel strip. When a reverse current passes through, the magnetic suction block is released, thus releasing the restriction on the stainless steel strip and achieving the purpose of fixing the workpiece. At the same time, the position of the magnetic suction blocks at both ends can be flexibly adjusted by rotating the forward and reverse screws, which can be used to position workpieces of different sizes. Furthermore, in conjunction with the function of the heat-conducting plate, the heat-conducting plate can assist in heat dissipation and cooling of the workpiece when in contact with it.

[0014] 2. This utility model, through the design of the insertion and engagement of the ball and the slot, can limit and lock the forward and reverse screws in a stationary state, which can prevent the random rotation of the forward and reverse screws from affecting the stability of the connecting rod and the slide. It can also improve the stability of the position of the magnetic pressure block after adjustment, and avoid the impact of insufficient stability on the pressing and positioning effect. Furthermore, under the contact action between the friction block and the forward and reverse screws, it can provide resistance to the rotation of the forward and reverse screws, which can further improve the limiting effect of the forward and reverse screws.

By designing the fixing blocks 86, the guide rods 85 can be supported. A support seat 87 is rotatably sleeved on the outside of the positive and negative screw 81. The support seat 87 is fixedly connected to the worktable 1. By designing the adjustment mechanism 8, the horizontal position of the slide block 3 can be easily adjusted.

[0024] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5The locking mechanism 9 includes a slot 91. A slot 91 is formed inside the positive and negative screw 81. A ball 92 is movably fitted inside the slot 91. There are multiple slots 91, evenly distributed inside the positive and negative screw 81. By designing multiple slots 91, the ball 92 can roll into different positions within the slots 91. The ball 92 is movably connected to the support base 87. A slider 93 is movably fitted outside the ball 92. The slider 93 is slidably connected to the support base 87. A fixing rod 94 is slidably fitted inside the slider 93. The fixed rod 94 is fixedly connected to the support base 87. A spring 95 is provided on the outside of the fixed rod 94.

By designing the spring 95, the force of the spring 95 can be applied to the slider 93. A friction block 96 is fixedly connected to the lower end of the slider 93. The friction block 96 is slidably connected to the support base 87. The friction block 96 is in contact with the outer surface of the positive and negative screws 81. By designing the locking mechanism 9, the stationary positive and negative screws 81 can be limited and locked.

[0025] The specific implementation process of this utility model is as follows: When in use, the workpiece is first placed on the heat-conducting plate 10, and then a positive current is passed through the electro-permanent magnet 4. The magnetic suction block 6 moves downward under the influence of magnetic force. The magnetic suction block 6 will drive the slide rod 5 to slide down along the slide seat 3, so as to press and fix the stainless steel strip. Then the welding work can be carried out. During welding, in conjunction with the function of the heat-conducting plate 10, the heat-conducting plate 10 can contact the workpiece to assist in heat dissipation and cooling of the workpiece.

[0026] When the position of the magnetic pressure block 6 needs to be adjusted, the motor 7 is started. The output end of the motor 7 drives the positive and negative screws 81 to rotate, causing the connecting rod 83 to make threaded movement. The connecting rods 83 at both ends will move in opposite directions. The connecting rods 83 drive the fixing ring 84 to slide along the guide rod 85. The connecting rods 83 will drive the slide block 3 to move horizontally, so that the position of the magnetic pressure block 6 can be flexibly adjusted and can be used for positioning workpieces of different sizes.

[0027] During the rotation of the forward and reverse screws 81, the forward and reverse screws 81 will rotate relative to the retaining ball 92. The arc surface of the retaining groove 91 inside the forward and reverse screws 81 will squeeze and push the retaining ball 92, causing the retaining ball 92 to roll upward. The retaining ball 92 will drive the slider 93 to slide along the fixed rod 94 and squeeze the spring 95. At the same time, the slider 93 will drive the friction block 96 to move upward. After the forward and reverse screws 81 have finished rotating, the elasticity of the spring 95 will give the slider 93 a downward push, which can push the retaining ball 92 into the retaining groove 91 in another position. At the same time, the friction block 96 contacts the positive and negative screws 81, which can limit and lock the positive and negative screws 81 in a stationary state. This can prevent the random rotation of the positive and negative screws 81 from affecting the stability of the connecting rod 83 and the slide block 3. It can also improve the stability of the position of the magnetic suction block 6 after adjustment, and avoid the impact of insufficient stability on the pressing and positioning effect. Furthermore, under the contact action between the friction block 96 and the positive and negative screws 81, it can provide resistance to the rotation of the positive and negative screws 81, which can further improve the limiting effect of the positive and negative screws 81.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
