Description

Technical Field

[0001] The utility model relates to the technical field of saw blade processing, in particular to an edge gear turning device used for circular saw blade processing. Background Art

[0002] Tooth welding is an important process in the processing of circular saw blades. During this process, the circular saw blade needs to rotate stably, and the teeth are welded in sequence using a tooth welding machine. The center of the circular saw blade is fixed on the tooth flange of the center tooth rotating equipment. The tooth flange keeps the circular saw blade rotating stably, but the welding process will generate welding heat, which will be transferred to the tooth flange, causing heat to accumulate in the center of the circular saw blade, and then deformation will occur. This deformation will cause the accuracy of the welded teeth to drop sharply. In addition, when the diameter of the circular saw blade is large, in order to ensure the stability of the circular saw blade and thus ensure the accuracy of the welded teeth, the accuracy requirements of the center tooth rotating equipment will increase significantly, which will inevitably result in a substantial increase in costs. Based on this situation, how to avoid the reduction of the welding tooth accuracy of the circular saw blade due to the accumulation of welding heat and the lack of its own accuracy in the center tooth rotating equipment as much as possible is becoming an issue that relevant technical personnel urgently need to solve.

[0006] Furthermore, a secondary slide groove is symmetrically arranged through the front part of the base, and the secondary slide groove runs in the left and right directions. The left sliding seat and the right sliding seat are respectively slidably connected to the corresponding secondary slide grooves.

[0007] Furthermore, an inner cavity is provided inside the base, a rear mounting plate is fixedly provided at the middle position of the rear part of the base, a cylinder is fixedly provided at the rear part of the rear mounting plate, an output end of the cylinder horizontally penetrates the rear mounting plate forward, a connecting seat is fixedly provided at the output end of the cylinder, a column is fixedly provided at the front part of the connecting seat, a left air claw is provided at a position inside the inner cavity corresponding to the left mounting plate, a right air claw is provided at a position inside the inner cavity corresponding to the right mounting plate, the rear ends of the left and right air claws are rotatably connected to the column, the front end of the left air claw is movably connected to the left sliding seat, and the front end of the right air claw is movably connected to the right sliding seat.

[0008] Furthermore, a main slide groove is provided through the middle position of the base, the main slide groove runs in the front-back direction, and the column is slidably connected to the main slide groove.

[0009] Furthermore, an oil seal is fixedly provided at the front of the driving wheel and the driven wheel, the diameter of the oil seal is larger than the diameter of the driving wheel and the driven wheel, and a cover plate is fixedly provided at the front of the oil seal.

[0010] The beneficial effects of the edge gear turning device for circular saw blade processing of the utility model are:

[0011] 1. This equipment is used in conjunction with a horizontal hanging rod. The hanging rod passes through the center of the circular saw blade and is hung in the middle between the driving wheel and the driven wheel. The staff only needs to start the cylinder and move its output end forward to clamp the edge of the circular saw blade through the oil seal. The servo motor only needs to be started to make the circular saw blade rotate stably through the cooperation of the driving wheel and the driven wheel. The clamping and driving are both located at the edge of the circular saw blade and the position moves continuously, which effectively avoids the situation where the center position of the circular saw blade is deformed due to the accumulation of welding heat and the welding tooth accuracy is reduced, effectively ensuring the welding tooth accuracy of the circular saw blade;

[0012] 2. The oil seal is always at the edge of the circular saw blade. Even if the diameter of the circular saw blade is large, it will not shake irregularly during the welding process. The stability can always be guaranteed, which effectively avoids the situation where the welding precision of the circular saw blade is reduced due to the insufficient precision of the center gear rotating equipment, and further ensures the welding precision of the circular saw blade;

[0013] 3. The diameter of the oil seal is larger than that of the driving wheel and the driven wheel, which effectively ensures direct contact between the oil seal and the circular saw blade, rather than direct contact between the driving wheel and the driven wheel and the circular saw blade. Due to the material, the hardness of the oil seal is much smaller than the hardness of the metal material commonly used for the driving wheel and the driven wheel, thereby effectively avoiding scratches on the circular saw blade during the operation of the equipment.

[0029] The working principle of the edge gear turning device for circular saw blade processing of the utility model is as follows: the matching horizontal hanging rod is passed through the center position of the circular saw blade, so that the circular saw blade is vertically suspended at the middle position between the driving wheel 6 and the driven wheel 5, the cylinder 2 is started, and the output end of the cylinder 2 pushes the connecting seat 20 to move forward horizontally, the sliding connection between the column and the main slide 12 keeps the forward movement of the column stable, the column drives the left air claw 21 and the right air claw 19 to rotate synchronously, the left air claw 21 and the right air claw 19 respectively drive the left sliding seat 22 and the right sliding seat 18 to approach each other at the same time, the left sliding seat 22 and the right sliding seat 18 are slidably connected to the auxiliary slide 13, the left slider 10 and the right slider 11 are slidably connected to the slide rail 14, so that the left mounting plate 9 and the right mounting plate 1 5 are close to each other while maintaining sufficient stability until the oil seals 24 at the front of the driving wheel 6 and the driven wheel 5 clamp the edge of the circular saw blade, and the servo motor 1 is started. After the output shaft of the servo motor 1 is decelerated by the reducer 7, the driving wheel 6 rotates at a suitable speed. Since the oil seal 24 has clamped the circular saw blade, the driving wheel 6 and the driven wheel 5 cooperate to make the circular saw blade rotate stably. The rotation process is intermittent rotation. Between two rotations, the gear welding machine performs gear welding. This equipment will not cause the center position of the circular saw blade to deform and reduce the welding tooth accuracy due to the accumulation of welding heat like the center gear rotating equipment. In addition, the oil seal 24 clamps the circular saw blade at the edge of the circular saw blade, which will not cause irregular shaking of the circular saw blade, so that the welding tooth accuracy can be always guaranteed.
