Description

Technical Field

[0001] This invention relates to the field of saw tooth welding device technology, specifically a saw tooth welding device with a saw blade. Background Technology

[0002] Metal saw blades are a commonly used cutting tool that can be used with various types of band saws; Metal saw blades are equipped with evenly distributed saw teeth, which can cut objects. A welding device is needed when installing the saw teeth. In the prior art, Chinese invention patent CN115673638B discloses a saw blade saw tooth welding device, including a main body. A box is located in the middle of the bottom of the main body. Evenly distributed fans are fixedly connected to the left side wall of the box. The fans are all located to the left of a filter screen. A dust collection chamber is located to the right of the filter screen. A suction pipe is located on the right side of the top of the box. The end of the suction pipe away from the box passes through a fixing block and is fixedly connected to a dust collection hood. A welding mechanism is located at the rear side of the top center of the workbench. In this invention, a box is located inside the main body of the device, and fans are located inside the box. Activating the fans creates negative pressure inside the box, allowing the dust generated during welding to be collected through the suction pipe and dust collection hood. The sucked-in dust falls into the dust collection chamber under the obstruction of the filter screen and gravity, making it convenient for users. In the above technology, a box is set inside the main body of the device, and a fan is set inside the box. The fan creates negative pressure inside the box, so that the dust generated during welding can be collected through the dust suction pipe and dust suction hood during use. Due to the lubrication effect, the surface of the transmission screw is coated with lubricating oil. The lubricating oil has an adsorption effect, and some dust and debris will adhere to the surface of the transmission screw. During the sliding of the slider, dust and debris can easily enter the inside of the slider, resulting in a shortened machine life. Summary of the Invention

[0007] Furthermore, the fixing frame is provided with a clamping frame, and a second guide block is installed at the lower end of the clamping frame corresponding to the position of the first guide groove. The second guide block is screwed onto the first guide groove. The clamping frame moves above the fixed frame through the cooperation of the first guide groove and the second guide block.

[0008] Furthermore, the clamping plate is disposed above the clamping frame; At least one set of second guide grooves are provided on the upper end face of the clamping frame. A second drive shaft is rotatably arranged inside the second guide groove. A second motor is installed on the side wall of the clamping frame at the end position corresponding to the second drive shaft.

[0010] Furthermore, a cleaning sleeve is installed on both the first guide block and the second guide block at positions corresponding to the second drive shaft and the first guide groove. The cleaning sleeve is fitted over the outside of the first guide groove and the second guide block, and a first storage groove is provided at one end of the cleaning sleeve. A cleaning ring is inserted into the inside of the first storage groove.

[0011] Furthermore, multiple sets of circumferentially distributed first return springs are provided between the end of the cleaning ring and the inner wall of the first storage groove, and the cleaning ring is elastically connected to the cleaning sleeve through the first return springs; The cleaning ring is provided with bristles at positions corresponding to the first guide groove and the second drive shaft.

[0012] Furthermore, the cleaning sleeve has an oil storage cavity inside, and the inner wall of the oil storage cavity has a second through hole penetrating the inner wall of the cleaning sleeve. A baffle is provided inside the oil storage cavity at the position corresponding to the second through hole. A connecting groove is provided between the oil storage chamber and the first receiving groove. A connecting plate is provided inside the connecting groove. The two ends of the connecting plate are respectively connected to the end of the cleaning ring and the end of the cover plate. An oil outlet hole is provided on the connecting plate near the cover plate.

[0013] Furthermore, a second storage groove is provided on the inner wall of the cleaning sleeve at the position corresponding to the second through hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The present invention clamps the band saw blade with a clamping plate, which facilitates welding with a welding gun. During the welding process, the cooperation of the first drive shaft and the second guide block drives the band saw blade to move. At the same time, it drives the cleaning ring on the cleaning sleeve to move along the first guide groove, and the surface of the first guide groove is cleaned by the bristles on the cleaning ring. If debris adheres to the first guide groove, it will affect the cleaning of the cleaning ring. At this time, the cleaning ring is held back by the debris. The cleaning ring pushes the connecting plate to move through the connecting plate. The connecting plate compresses the internal space of the oil storage chamber. As the internal space of the oil storage chamber shrinks, the lubricating oil in the oil storage chamber is injected into the area above the second through hole through the oil outlet on the connecting plate. When the baffle plate contacts the extrusion plate, the extrusion plate pulls the sealing plate to move through the pull rope, so that the first through hole and the second through hole coincide. At this time, the lubricating oil on the second through hole drips out. As the cleaning sleeve moves, it begins to lubricate the first guide groove. Attached Figure Description
