Description

Technical Field

[0001] The utility model relates to the technical field of saw blade welding machines, in particular to a saw blade guiding mechanism used for saw blade welding machines. Background Art

[0002] Current saw blades usually include a saw blade body and an alloy portion for processing a toothed portion, and the alloy portion and the saw blade body are fixed by welding, so a saw blade welding machine is required.

[0003] The existing welding machine needs to use a guide mechanism when welding saw blades. For example, patent number CN205764497U discloses a base plate, a first guide roller rotatably set on the base plate, a second guide roller rotatably set above the first guide roller, a third guide roller rotatably set on the base plate, and a fourth guide roller.

[0004] In the above scheme, the saw blade is guided and welded by a guide roller. However, in actual use, it is found that due to the different widths of different saw blades, the conventional guide roller is longer and the roller wall is smoother, and the saw blade will be offset during the guiding movement, thereby reducing the welding accuracy of the saw blade. Therefore, a saw blade guide mechanism for a saw blade welding machine is proposed. Utility Model Content

[0005] The utility model aims to solve the problems raised by the background technology and proposes a saw blade guiding mechanism for a saw blade welding machine.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A saw blade guide mechanism for a saw blade welding machine comprises a base plate and two guide rollers, wherein two side plates are symmetrically fixedly arranged on the surface of the base plate, the two guide rollers are symmetrically arranged between the two side plates, guide plates are arranged on both sides of the tops of the two guide rollers, sliding rods are fixedly arranged on the opposite sides of the guide plates on both sides, and the sliding rods are slidably connected to the side plates, movable plates are arranged on both sides of the two side plates, the two movable plates are fixedly connected to one end of the sliding rod, a bidirectional screw is rotatably arranged between the two side plates, and the two movable plates are threadedly connected to both ends of the bidirectional screw.

[0008] Preferably, a manual turntable is fixedly provided in the middle of the rod wall of the bidirectional screw.

[0009] Preferably, anti-fall-off blocks are fixedly provided at both ends of the bidirectional screw.

[0010] Preferably, a plurality of evenly distributed mounting grooves are provided on the side surface of the guide plate, and auxiliary rollers are rotatably provided inside the mounting grooves.

[0011] Preferably, the guide roller and the auxiliary roller are both rubber rollers.

[0012] Preferably, a threaded hole is provided on the top of the side surface of the movable plate, and the rod wall of the bidirectional screw is threadedly connected to the movable plate through the threaded hole.

[0013] Compared with the prior art, the utility model provides a saw blade guide mechanism for a saw blade welding machine, which has the following beneficial effects:

[0014] 1. The saw blade guiding mechanism for the saw blade welding machine is provided with guide plates. Since the guide plates on both sides are arranged above the guide rollers on both sides, when the saw blade is guided and moved on the roller walls of the two guide rollers, the guide plates on both sides play a limiting role, which can reduce the degree of deviation of the saw blade on the guide roller, thereby realizing the role of precise guiding of the saw blade and improving the welding accuracy.

[0015] 2. The saw blade guiding mechanism for the saw blade welding machine is equipped with a sliding rod, a movable plate and a bidirectional screw. When it is necessary to adjust the spacing between the guide plates on both sides, the manual turntable is turned to rotate the bidirectional screw. During the rotation, the bidirectional screw can drive the two movable plates to move closer or farther away from each other, so that the two sliding rods drive the guide plates on both sides to move closer or farther away from each other, thereby accurately guiding saw blades of different widths and improving versatility.

[0016] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model is provided with a guide plate above the guide roller, which can limit the side position of the saw blade during the guiding movement, thereby realizing the function of precise guiding of the saw blade and improving the welding accuracy. At the same time, the spacing between the guide plates on both sides can be adjusted, thereby improving the versatility of the welding machine. BRIEF DESCRIPTION OF THE DRAWINGS
