Abstract
Description
Technical Field
[0001] This utility model relates to the field of silver soldering fixture technology, specifically an adjustable height hard pipe silver soldering fixture. Background Technology
[0002] Silver soldering is a welding method that uses silver solder as the welding material. Silver solder possesses characteristics such as a low melting point, good wettability, high strength, excellent electrical conductivity, and corrosion resistance. During the welding process, the silver solder is melted using welding equipment, allowing it to join with the metal workpiece. Due to its superior performance, silver soldering is widely used in industrial manufacturing fields such as engineering machinery, mining machinery, and aerospace. Silver soldering fixtures are used to fix the workpiece in place, ensuring welding accuracy and preventing movement or deformation during the welding process.
[0003] Currently, precise positioning is crucial in silver soldering, directly affecting the strength and reliability of the welded joint. Traditional tooling often suffers from limited positioning methods and adjustment ranges, making it difficult to meet the complex and ever-changing requirements of silver soldering. Products exceeding the tooling height cannot guarantee welding quality and precision, necessitating the fabrication of more tooling to match the silver soldering height for each product. This not only increases labor costs but also wastes manpower and reduces production efficiency. Therefore, we propose an adjustable-height rigid pipe silver soldering tooling fixture. Utility Model Content
[0004] The main objective of this invention is to provide an adjustable-height hard pipe silver soldering fixture that can solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention proposes an adjustable-height hard pipe silver soldering fixture, comprising a base plate, a side positioning plate fixedly connected to the outer wall of the base plate, a hand-cranked slide fixedly connected to the outer wall of the side positioning plate, and a rotating assembly provided on the hand-cranked slide, the rotating assembly comprising:
[0006] A lifting plate is fixedly connected to the movable end of the hand-cranked slide, and a rotating disk is rotatably connected to the top of the lifting plate;
[0007] A synchronizing gear is provided below the rotating disk, and a clamping assembly is fixedly connected to the top of the rotating disk;
[0008] A rotating rod is rotatably connected to the bottom of the lifting plate, and a drive gear is fixedly connected to the outer wall of the rotating rod.
[0009] Preferably, the rotating disk passes through the lifting plate, and a synchronous gear is fixedly connected to the outer wall of the rotating disk, the synchronous gear meshing with the driving gear.
[0010] Preferably, the lifting plate has a stepped through groove, and the outer wall of the rotating disk is rotatably connected to the inner wall of the stepped through groove.
[0011] Preferably, the base plate is provided with a clearance hole, and the rotating rod can slide into the clearance hole, so that the bottom can avoid the rotating rod.
[0012] Preferably, the base plate has a positioning slot, and the outer wall of the side positioning plate is fixedly connected to the inner wall of the positioning slot.
[0013] Preferably, a positioning seat is fixedly connected to the top of the base plate, and the top of the positioning seat is provided with an insertion hole, and a positioning pin is inserted into the inner wall of the insertion hole.
[0014] This utility model provides an adjustable-height silver soldering fixture for rigid pipes. It has the following advantages:
[0015] (1) This height-adjustable rigid pipe silver soldering fixture features a hand-cranked slide table, allowing for convenient adjustment of the lifting plate's height, which in turn drives the rigid pipe to rise and fall synchronously. This design effectively solves the problem of traditional fixtures being unable to adapt to welding products of different heights. It eliminates the need to create multiple fixtures for different heights, significantly reducing labor and manpower costs and improving production efficiency. In actual welding, operators only need to crank the hand-cranked slide table to quickly adjust the rigid pipe to the appropriate welding height, avoiding the time wasted by frequent fixture changes and ensuring production efficiency.
[0016] (2) The height-adjustable hard pipe silver soldering fixture uses a rotating bar to drive the drive gear to rotate. Through meshing with the synchronous gear, the rotating disk drives the clamping assembly to rotate, thereby achieving synchronous rotation of the clamped hard pipe. After welding the hard pipe to the joint, there is no need to loosen and re-fix the hard pipe. Simply rotating the rotating bar allows the hard pipe to drive the joint to rotate, moving the unwelded area to an operable position on the welding equipment. This simplifies the welding process, significantly improves welding efficiency, and effectively enhances the smoothness of the overall welding operation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0025] Please see Figures 1-4 This utility model proposes an adjustable height hard pipe silver soldering fixture, including a base plate 1, a side positioning plate 2 fixedly connected to the outer wall of the base plate 1, a hand-cranked slide 3 fixedly connected to the outer wall of the side positioning plate 2, a rotating assembly 4 provided on the hand-cranked slide 3, the rotating assembly 4 including a lifting plate 41, the movable end of the hand-cranked slide 3 fixedly connected to the lifting plate 41, the top of the lifting plate 41 rotatably connected to a rotating disk 42, a synchronous gear 43 provided below the rotating disk 42, and a clamping assembly 44 fixedly connected to the top of the rotating disk 42.
[0026] In this utility model, the clamping assembly 44 includes a clamping seat, a threaded rod, a guide rod, a clamping plate, and an adjusting block. The clamping seat has a C-shaped design. One end of the threaded rod is fixedly connected to the adjusting block, and the other end of the threaded rod is rotatably connected to the clamping plate. The threaded rod is threadedly connected to the inner wall of the clamping seat. The outer wall of the clamping plate is fixedly connected to the guide rod, and the outer wall of the guide rod is slidably connected to the inner wall of the clamping seat. Two sets of guide rods are provided on one set of clamping plates. One set consists of one threaded rod, two guide rods, one clamping plate, and one adjusting block. Two sets are provided on one clamping seat and are symmetrically designed. One set of clamping plates has a V-shaped groove, while the other set of clamping plates does not. By rotating the adjusting block, in conjunction with the threaded rod and the guide rod, the clamping plates can be moved. The rigid pipe product is clamped by the plane of one set of clamping plates and the V-shaped groove of the other set of clamping plates. This clamping assembly 44 can clamp rigid pipes of different diameters, improving the practicality of the device.
[0027] Furthermore, a rotating rod 45 is rotatably connected to the bottom of the lifting plate 41, and a drive gear 46 is fixedly connected to the outer wall of the rotating rod 45. The rotating disk 42 passes through the lifting plate 41, and a synchronous gear 43 is fixedly connected to the outer wall of the rotating disk 42. The synchronous gear 43 meshes with the drive gear 46. By rotating the rotating rod 45, the drive gear 46 can be driven to rotate. In conjunction with the meshing of the synchronous gear 43 and the drive gear 46, the synchronous gear 43 rotates, driving the rotating disk 42 to rotate. When the rigid tube is clamped, the clamping assembly 44 can be rotated by rotating the rotating disk 42, so that the clamped rigid tube rotates synchronously.
[0028] Furthermore, the lifting plate 41 has a stepped through groove 5, the outer wall of the rotating disk 42 is rotatably connected to the inner wall of the stepped through groove 5, the bottom plate 1 has a clearance hole 6, the rotating rod 45 can slide into the clearance hole 6, the clearance hole 6 allows the bottom to clear the rotating rod 45, the bottom plate 1 has a positioning slot 7, the outer wall of the side positioning plate 2 is fixedly connected to the inner wall of the positioning slot 7, the top of the bottom plate 1 is fixedly connected to a positioning seat 8, the top of the positioning seat 8 has an insertion hole 9, the inner wall of the insertion hole 9 is inserted with a positioning pin 10, the positioning pin 10 is modularly designed, the positioning pin 10 has various sizes, which is convenient to complete the connection with different connectors.
[0029] In use, by cranking the hand-cranked slide 3, the movable end on the hand-cranked slide 3 is raised and lowered, which in turn drives the lifting plate 41 to raise and lower. By passing the rigid tube through the rotating disk 42 and then rotating the adjusting block, the rigid tube is fixed on the clamping assembly 44. At this time, the raising and lowering of the lifting plate 41 will drive the rigid tube to rise and fall synchronously.
[0030] By adjusting the movable end of the hand-cranked slide table 3 to a suitable height, and then clamping the rigid pipe with the clamping assembly 44, the joint to be welded is placed on the positioning pin 10, and the rigid pipe is clamped to the position where the joint needs to be welded, so that the welding equipment can perform welding work.
[0031] After the rigid pipe and the connector have been partially welded and cooled down (i.e., the rigid pipe can move the connector synchronously), in order to perform welding work on the area behind, it is necessary to reposition the rigid pipe and the connector. If the rigid pipe is loosened, rotated, and then fixed, the process will be too complicated and affect work efficiency.
[0032] By rotating the rotating rod 45, in conjunction with the drive gear 46 and the synchronous gear 43, the rotating disk 42 is driven to rotate, which in turn drives the clamping assembly 44 to rotate, causing the clamped rigid tube to rotate synchronously. At this time, the rigid tube can drive the joint to rotate on the positioning pin 10, allowing other parts to move to the area of the welding equipment, facilitating subsequent complete welding work, quickly completing the repositioning work, and greatly improving work efficiency.
[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
