This results in high purchase costs and large space requirements for users, as well as frequent product turnover between different workstations and poor maintenance convenience. Furthermore, existing equipment is generally large, often occupying several square meters. For customers who specialize in welding small saw blades, these machines are bulky, difficult to transport, and require a large area. Moreover, their large size corresponds to high costs, making them uneconomical for small saw blade welding operations and resulting in poor adaptability. Utility Model Content

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-5 This utility model provides a band saw blade welding machine, including a machine body, a saw blade clamping and welding device 2, a grinding wheel device 3, and a manual cutting device 4. The grinding wheel device 3 and the manual cutting device 4 are respectively installed on the outer surface of the machine body, and their operating directions are consistent with the operating direction of the saw blade clamping and welding device 2. The saw blade clamping and welding device 2 includes a clamping assembly, a transformer, and an electrode assembly 23. A front plate 11 is provided on one side of the machine body, the clamping assembly is installed on the front plate 11, and the transformer is fixed inside the machine body. The electrode assembly 23 is electrically connected to the transformer (not shown in the figure). The electrode head of the electrode assembly 23 is directly contacted and tightly fitted to the clamping assembly. The clamping assembly includes a fixed plate 211 fixedly mounted on the front plate 11 and a movable plate 212 slidably mounted on the front plate 11. The fixed plate 211 and the movable plate 212 are respectively provided with U-shaped clamps 213 with opposite openings. The lower side of the U-shaped clamp 213 is tightly attached to the electrode head of the electrode assembly 23, and the upper side of the U-shaped clamp 213 is provided with a deformation trigger switch 214.

[0027] When clamping the saw blade, the deformation trigger switch 214 drives the upper side of the U-shaped clamp 213 to deform and expand the opening to facilitate the insertion of the saw blade. After the saw blade is placed stably, the deformation trigger switch 214 returns to its original position, thus automatically completing the clamping action of the saw blade. By using the U-shaped clamp 213 in conjunction with the deformation trigger switch 214, the opening and closing of the U-shaped clamp 213 can be flexibly controlled by deformation, easily achieving automatic clamping of the saw blade. The operation is simple and quick, reducing the difficulty and labor intensity of manual operation and improving work efficiency. This utility model integrates the saw blade clamping and welding, grinding wheel grinding and manual cutting devices into the machine body. The use direction of each device is consistent, covering the welding, grinding and cutting processes in one stop. There is no need for multiple machines to be moved around, which greatly reduces the purchase cost, saves workshop space, avoids the time-consuming turnover of materials at multiple workstations, and allows for centralized handling during maintenance. It is efficient and convenient, and the overall design is well adapted for small saw blades.

[0028] In this utility model, the U-shaped clamp 213 has an upper abutment portion 2131 and a lower abutment portion 2132 on its two sides at the opening. The upper abutment portion 2131 and the lower abutment portion 2132 are symmetrical and protrude along the direction close to the axis of symmetry. When the U-shaped clamp 213 clamps the band saw blade, it achieves clamping and fixing by the upper abutment portion 2131 and the lower abutment portion 2132 abutting against the upper and lower sides of the band saw blade respectively. Therefore, to achieve clamping or loosening of the band saw blade, the distance between the upper abutment portion 2131 and the lower abutment portion 2132 can be adjusted accordingly. This can be achieved by motor drive or manual triggering. However, in order to adapt to the overall miniaturization of the equipment, it is necessary to avoid using a motor to occupy more production space. Therefore, in this embodiment of the utility model, the distance between the upper abutment portion 2131 and the lower abutment portion 2132 is implemented by the triggering of the deformation trigger switch 214. The specific structural implementation will be explained below.

[0029] like Figure 2 As shown, the deformation trigger switch 214 in this embodiment of the present invention includes an eccentric transmission ring 2141 located on the upper side of the U-shaped clamp 213 and near the upper abutment part 2131, and an eccentric rotating shaft 2142 assembled in the eccentric transmission ring 2141. One end of the eccentric rotating shaft 2142 is axially connected to the movable plate 212 or the fixed plate 211, and the other end extends outward and is fixed with a knob handle 2143. When the knob handle 2143 is rotated, the eccentric rotating shaft 2142 rotates eccentrically around the shaft connection point, driving the eccentric transmission ring 2141 to transmit efficiently, converting the circumferential motion into the deformation action of the upper side of the U-shaped clamp 213, thereby controlling the opening and closing of the U-shaped clamp 213. The operation is labor-saving and flexible, making it easy to quickly insert or clamp the saw blade and improve work efficiency.

[0030] Furthermore, to facilitate the operator's rotation of the knob handle 2143 to control the opening and closing of the U-shaped clamp 213, the fixed end of the knob handle 2143 is fixedly mounted on the eccentric rotating shaft 2142, and the free end of the knob handle 2143 extends away from the opening of the U-shaped clamp 213. When the operator needs to clamp the band saw blade, they use the hand closest to the opening of the corresponding U-shaped clamp 213 to hold the band saw blade and insert it into the opening of the U-shaped clamp 213, while the other hand, which is relatively far away, is used to operate the knob handle 2143 to adjust the size of the opening of the U-shaped clamp 213. By setting the extension direction of the knob handle 2143 to be away from the opening of the U-shaped clamp 213, it can effectively adapt to the direction of force applied by the corresponding operator's hand, thus saving more effort and making it more convenient to use.

[0031] In this embodiment of the utility model, a linear bearing seat 2111 is fixed on the fixed plate 211, and a slider 2121 is provided on the movable plate 212. A transverse transmission component (not shown in the figure) connecting the slider 2121 is provided on the linear bearing seat 2111. By driving the slider 2121 to slide laterally, the movable plate 212 is moved laterally. When the band saw blades to be welded are clamped and fixed on both the fixed plate 211 and the movable plate 212, the relative distance and state between the two band saw blades can be driven by the movement of the movable plate 212. By setting the linear bearing seat 2111, a stable and precise guiding track is provided for the movement of the slider 2121, which greatly reduces the shaking and deviation that may occur when the movable plate 212 moves laterally.

[0032] like Figure 1 As shown, the grinding wheel device 3 in this embodiment includes a grinding wheel fixing frame 31, a grinding wheel drive motor (not shown in the figure), and a grinding wheel body 33. The grinding wheel fixing frame 31 is fixedly installed on the upper end of the machine body housing. The grinding wheel drive motor is installed inside the grinding wheel fixing frame 31. The output end of the grinding wheel drive motor extends out of the outer surface of the grinding wheel fixing frame 31 and connects to the grinding wheel body 33. The upper end of the grinding wheel fixing frame 31 is provided with a handle 34. By firmly installing the grinding wheel fixing frame 31 on the upper end of the machine body housing, the vertical space is fully utilized, making the overall layout of the machine compact and reasonable, avoiding occupying too much plane area, and facilitating operation by the operator in a natural standing posture, conforming to ergonomics and reducing labor intensity. This product has a simple and compact structure and a light overall weight. By adding a handle 34 to the upper end of the fixing frame, the equipment can be easily moved with the help of the handle 34, adapting to the movement and transportation of miniaturized equipment. It can be moved and adapted to use in a variety of application environments, making it highly practical.

[0033] Furthermore, the outer surface of the grinding wheel fixing frame 31 is provided with a protective cover 311 surrounding the outside of the grinding wheel body 33, which blocks the debris particles that may be splashed out by the high-speed rotating grinding wheel body 33 during operation, reducing the risk of accidental injury to the operator's eyes, face and other parts of the body.

[0034] In addition, the lower end of the grinding wheel fixing frame 31 in this embodiment of the present invention is provided with a baffle 312. The baffle 312 is located directly below the grinding wheel body 33. When the grinding wheel body 33 performs grinding operations on the welded band saw blade, it can intercept falling metal chips, abrasive particles and other waste materials, effectively preventing them from scattering to the ground around the equipment or falling into the welding process and affecting the welding quality. In addition, with the protective cover 311, it is convenient to collect and recycle the grinding debris.

[0035] In this embodiment of the utility model, the front plate 11 is provided with a control panel 12. The control panel 12 is provided with a welding tempering control switch 121 and a butt welding pressure control switch 122 that are electrically connected to the transformer. The butt welding pressure control switch 122 is electrically connected to the transverse transmission component, so that the output voltage intensity of the transformer and the butt welding pressure intensity of the welding rod can be adjusted according to actual needs.

[0036] Before using the equipment, prepare by cutting the ends of the saw blade to be joined at a 90° angle using the manual cutting device 4. Then, perform the welding operation: clamp the two ends to be joined onto the two U-shaped clamps 213. Select the appropriate setting for the welding tempering control switch 121 and the joining pressure control switch 122 according to the size of the saw blade. Then, heat the weld joint until it turns from red to white and stop heating. You can use compressed air to cool it quickly to achieve a quenching effect. Next, perform the tempering operation: when the weld joint temperature drops to about 200 degrees Celsius, turn on the welding tempering control switch 121 for 2-5 seconds. When the weld joint temperature reaches 700 degrees Celsius, disconnect the power and use compressed air to cool it quickly. Finally, remove the welded saw blade and grind the welded joint smooth using the grinding wheel device 3 to complete the welding work.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application shall fall within the scope of the technical solution of this application.
