Description

Technical Field

[0001] This utility model relates to the field of bimetal saw blade welding technology, and in particular to a bimetal saw blade welding clamping fixture. Background Technology

[0002] Bimetal band saw blades mainly refer to metal cutting band saw blades with high-speed steel or other high-performance steel for the tooth tip and low-alloy spring steel for the saw band. These blades have a wide range of applications and can be used with any type of band saw. They are suitable for continuous sawing of almost all types of metals. However, bimetal band saw blades are finished as rings with fixed clamping positions, which is the clamping method used when welding the ends. When welding the two metal strips together, the fixed clamping position requires frequent loosening and tightening to continuously weld the strip of metal. This leads to frequent machine shutdowns and low efficiency.

[0003] To address the aforementioned issues, existing patent (CN117020521A) discloses a clamping fixture for welding bimetallic saw blades. This fixture opens and closes via a telescopic cylinder, and rollers are mounted in the center of the clamping plate via an elastic pressure frame. It provides two clamping states: when the metal strip needs to be fixed, the clamping plate contacts the metal strip surface for compression and fixation; when rolling clamping is required, the rollers, in conjunction with the elastic pressure frame, clamp the metal strip in a rolling manner. A sufficiently elastic spring prevents slippage between the metal strip and the rollers, allowing the metal strip to be rotated and pushed for movable clamping, thus facilitating continuous welding.

[0004] However, the aforementioned existing technologies have poor stability when fixing and welding metal saw blades, resulting in poor welding results. Utility Model Content

[0005] The purpose of this utility model is to provide a bimetallic saw blade welding clamping fixture, which aims to solve the technical problem in the prior art that the stability is poor when fixing and welding metal saw blades, resulting in poor welding effect.

[0006] To achieve the above objectives, this utility model employs a bimetallic saw blade welding clamping fixture, comprising a base, a base plate, and a clamping assembly. The base is fixedly connected to the base plate and is located below the base plate. The clamping assembly includes a positioning block, a telescopic rod, a spring, a clamping block, a clamping component, and a moving component. The positioning block is fixedly connected to the base plate and located above the base plate. The telescopic rod is located above the base plate. The clamping block is detachably connected to the telescopic rod and located at one end of the telescopic rod. The spring is detachably connected to the clamping block and wraps around the telescopic rod. The clamping component is located above the base plate, and the moving component is located above the base plate.

[0007] The clamping component includes a fixed shell, a fixed cover, a clamping plate, and a driving unit. The clamping plate is detachably connected to the telescopic rod and is located on the side of the telescopic rod away from the clamping block. The fixed shell is slidably connected to the clamping plate and is located above the clamping plate. The fixed cover is detachably connected to the fixed shell and is located above the fixed shell. The driving unit is disposed inside the fixed shell.

[0008] The drive unit includes a gear, a rack, and a moving block. The moving block is detachably connected to the clamping plate and is located inside the fixed shell. The rack is detachably connected to the moving block and is located inside the fixed shell, and the rack is slidably connected to the fixed shell. The gear meshes with the rack and is located inside the fixed shell.

[0009] The movable component includes a limiting rod, a top plate, a mounting plate, a threaded rod, and a moving unit. The limiting rod is fixedly connected to the bottom plate and located above the bottom plate. The top plate is fixedly connected to the limiting rod and located above the limiting rod. The mounting plate is fixedly connected to the top plate and located below the top plate. The threaded rod is rotatably connected to the mounting plate and located inside the mounting plate, with the threads at both ends of the threaded rod having opposite directions. The moving unit is located below the top plate.

[0010] The moving unit includes a first connecting block, a swing arm, and a second connecting block. The first connecting block is threadedly connected to the threaded rod and wraps around the threaded rod. One end of the swing arm is rotatably connected to the first connecting block and is located inside the first connecting block. The second connecting block is rotatably connected to the swing arm and is located at the end of the swing arm away from the first connecting block. The second connecting block is detachably connected to the fixed cover.

[0011] This utility model discloses a bimetallic saw blade welding clamping fixture. One metal saw blade is fixed inside the positioning block. Simultaneously, the clamping motor is started, driving the gear to rotate. The rotation of the gear can drive the rack and the clamping plate to move, thereby driving the clamping block to move. With the cooperation of the telescopic rod and the spring, the clamping block clamps and fixes the other metal saw blade. Since the gear and rack in the clamping component and the threaded rod and the first connecting block in the moving component are all self-locking, the stability during the welding process is higher, and the welding quality is increased.

With the cooperation of the telescopic rod 104 and the spring 105, the clamping block 106 clamps and fixes another metal saw blade. Since the gear 110 and the rack 111 in the clamping component and the threaded rod 116 and the first connecting block 117 in the moving component can all be self-locking, the stability during the welding process is higher, and the welding quality is increased.

[0023] Furthermore, the clamping component includes a fixed housing 107, a fixed cover 108, a clamping plate 109, and a driving unit.

The moving unit is located below the top plate 114.

[0028] In this embodiment, starting the mobile motor 121 to drive the threaded rod 116 to rotate can drive the fixed shell 107 to move up and down through the moving unit, thereby driving the saw blade fixed by the clamping block 106 to move up and down and adjust its height.

[0029] Furthermore, the moving unit includes a first connecting block 117, a swing rod 118, and a second connecting block 119. The first connecting block 117 is threadedly connected to the threaded rod 116 and wraps around the threaded rod 116. One end of the swing rod 118 is rotatably connected to the first connecting block 117 and is located inside the first connecting block 117.
