Description

Technical Field

[0001] The present invention relates to the technical field of hand pliers type cold welders, and particularly to a hand pliers type cold welder with a limiting mechanism. Background Art

[0002] In the fields of modern industrial manufacturing and maintenance, cold welding technology has attracted much attention because it can achieve material connection at relatively low temperatures, especially suitable for welding heat-sensitive materials or precision components. However, there are many problems in the actual use of existing hand pliers type cold welders. Traditional equipment usually controls the opening and closing of the welding components through simple handle operations, lacking effective linkage mechanisms and limiting devices, resulting in difficult precise control of the opening and closing distance of the welding components, insufficient welding precision, and prone to situations of insecure welding or over-welding.

[0003] At the same time, operators need to frequently and forcefully squeeze the handle, which is easy to cause fatigue during long-term operation, reducing work efficiency and increasing the risk of operation errors. In addition, existing equipment does not limit the movement range of the handle, and it is easy to damage the welding components due to excessive squeezing or opening, even affecting the service life and welding precision of the welding components.

[0004] In view of the above problems, there is an urgent need for innovative design based on the original hand pliers type cold welder. Summary of the Invention

[0005] The technical solution of the present invention provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single, so as to solve the problems raised in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: A hand pliers type cold welder with a limiting mechanism, including a base, on one side of the base is installed a cold welding component for welding, and on the other side of the base at both ends are respectively provided with a groove, and in each groove is rotatably connected a rotating shaft for linking the cold welding component, on the outer wall of each rotating shaft is connected a handle rod for holding, and at the end of each rotating shaft and on the base is provided a triggering structure, and on the side of the base is connected an adjustment and limiting structure for linking the triggering structure.

[0007] Preferably, the triggering structure includes a box body, a piston rod, a full gear, and a delivery pipe. The box body is installed on the base, and on both sides inside the box body are respectively provided a piston rod, and the end of each piston rod respectively penetrates through both sides of the box body and is connected with a full gear. On the upper end of each rotating shaft is connected a full gear. In the middle area of the box body is communicated with a delivery pipe, and the end of the delivery pipe is connected to the adjustment and limiting structure.

[0008] Preferably, the piston rod is arranged in a "T" shape, and a tooth block for meshing with the full gear is arranged at the outer end area of the box body of the piston rod.

[0009] Preferably, the adjusting and limiting structure includes a mounting frame, a cylinder barrel, a sliding cylinder, a threaded rod, a rotating shaft member, a sliding block, and a sliding groove. The mounting frame is connected to the side of the base, and two cylinder barrels are rotatably connected to the mounting frame through brackets. A sliding cylinder is slidably connected in each cylinder barrel. A threaded rod is threadedly connected in each sliding cylinder. The end of each threaded rod passes through the corresponding sliding cylinder and is rotatably connected to a rotating shaft member. The end of each rotating shaft member is rotatably connected to a sliding block. Each sliding block is connected to a sliding groove, and the sliding groove is formed in two handle rods.

[0010] Preferably, the mounting frame is arranged in an "L" shape, and the mounting frame is connected to the area between the two handle rods on the side of the base.

[0011] Preferably, the sliding groove penetrates through the upper and lower end faces of the handle rod, and the sliding groove and the sliding block are in a snap-fit sliding connection.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: For the hand-held pliers type cold welding machine with a limiting mechanism, through the pinching and opening actions of the handle rods, the rotating shaft and the full gear are driven to rotate, and then the piston rod is driven to move in the box body, realizing the precise control of the cold welding component, ensuring the stable clamping and precise welding of the workpiece during the welding process, thereby improving the welding quality and efficiency. At the same time, the sliding cylinder in the cylinder barrel drives the sliding block to move in the sliding groove through the threaded rod and the rotating shaft member. On the one hand, it assists the pinching and opening operations of the handle rods, reducing the labor intensity of the operator; on the other hand, it limits the degree of mutual approach and opening when pinching the handle rods, preventing damage to the welding component or poor welding effect caused by excessive operation, and improving the reliability and safety of the equipment; In addition, the equipment of the present invention also has an adjustable limiting degree. By pre-rotating the threaded rod, the distance between the sliding block and the cylinder barrel can be adjusted, and then the rotational limiting degree of the handle rod can be changed, which can be flexibly adjusted according to different welding requirements and workpiece sizes, enhancing the versatility and adaptability of the equipment, and enabling it to meet the needs of various welding scenarios; The hydraulic oil or air is transmitted between the box body and the cylinder barrel by using a delivery pipe, realizing an efficient transmission effect. It can not only quickly respond to the operation actions but also provide a stable power output, ensuring the continuity and stability of the welding process. BRIEF DESCRIPTION OF THE DRAWINGS

And a rotating shaft 4 for linking the cold welding component 2 is rotatably connected in each groove 3. A handle rod 5 for holding is connected to the outer wall of each rotating shaft 4. And a trigger structure 6 is provided at the end of each rotating shaft 4 and the base 1. An adjustment and limit structure 7 for linking the trigger structure 6 is connected to the side of the base 1.

[0017] The trigger structure 6 includes a box body 601, a piston rod 602, a full gear 603, and a conveying pipe 604. A box body 601 is installed on the base 1. And two piston rods 602 are respectively provided on both sides inside the box body 601. And a full gear 603 is respectively connected to the end of each piston rod 602 through both sides of the box body 601. A full gear 603 is connected to the upper end of each rotating shaft 4. A conveying pipe 604 is communicated with the middle area of the box body 601. And the end of the conveying pipe 604 is connected to the adjustment and limit structure 7.

[0018] The piston rod 602 is set in a "T" shape, and a tooth block for meshing with the full gear 603 is provided at the outer end area of the piston rod 602 located outside the box body 601.

[0019] The adjustment and limit structure 7 includes a mounting frame 701, a cylinder barrel 702, a sliding cylinder 703, a threaded rod 704, a rotating shaft member 705, a sliding block 706, and a sliding groove 707. The mounting frame 701 is connected to the side of the base 1, and two cylinder barrels 702 are rotatably connected to the mounting frame 701 through brackets. A sliding cylinder 703 is slidably connected to each cylinder barrel 702. A threaded rod 704 is threadedly connected to each sliding cylinder 703. The end of each threaded rod 704 passes through the corresponding sliding cylinder 703 and is rotatably connected to a rotating shaft member 705. The end of each rotating shaft member 705 is rotatably connected to a sliding block 706. Each sliding block 706 is connected to a sliding groove 707, and the sliding groove 707 is formed in the two handle rods 5.

[0020] The mounting frame 701 is set in an "L" shape, and the mounting frame 701 is connected to the area between the two handle rods 5 on the side of the base 1.

[0021] The sliding groove 707 penetrates the upper and lower end faces of the handle rod 5, and the sliding groove 707 and the sliding block 706 are in a snap-fit sliding connection.

[0022] Working principle: According to the usage requirements, place the corresponding mold into the cold welding component 2 for fixing and then it can be used for welding. During the welding process, by continuously squeezing and opening the handle rods 5 multiple times, when driving the linked cold welding component 2 to weld the workpiece between the molds, squeezing the handle rod 5 drives the rotating shaft 4 and the full gear 603 thereon to rotate. Since the two handle rods 5 move closer to each other, the two rotating shafts 4 and the full gears 603 rotate in opposite directions, so that the two full gears 603 drive the engaged piston rod 602 to move outward from the box body 601. During this process, the hydraulic oil or air in the cylinder barrel 702 is pumped into the box body 601 through the delivery pipe 604; This causes the sliding cylinders 703 in the two cylinder barrels 702 to move inward. Through the threaded rod 704 and the rotating shaft member 705 connected to the sliding cylinder 703, the sliding block 706 is driven to move in the corresponding sliding groove 707. During this process, on the one hand, it can play a certain role in assisting the operation of squeezing the handle rod 5, and on the other hand, it can limit the degree of approaching each other when squeezing the handle rod 5; When the two handle rods 5 are opened, on the contrary, the two spur gears 603 drive the two meshing connecting piston rods 602 to move out of the box body 601, and push the hydraulic oil or air in the box body 601 into the cylinder barrel 702 through the conveying pipe 604. In this process, the sliding cylinder 703 moves out of the cylinder barrel 702, and through the threaded rod 704 and the rotating shaft member 705, the sliding block 706 is pushed to move in the sliding groove 707, achieving the effects of assisting in opening and limiting the opening degree. According to the usage requirements, the threaded rod 704 can be pre-rotated so that the threaded rod 704 moves outwards from the sliding cylinder 703 by the required distance, thereby changing the length between the sliding block 706 and the corresponding cylinder barrel 702, and further achieving the adjustment of the rotation limit of the handle rod 5. This is the working principle of the pliers-type cold welder with a limiting mechanism.

[0023] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
