Description

A grinding wheel saw blade auxiliary tooling Technical Field

[0001] This utility model relates to the field of grinding wheel saw blade processing technology, specifically to an auxiliary tooling for grinding wheel saw blades. Background Technology

[0002] Grinding saw blades, widely used in metal processing and stone cutting, typically consist of a disc base and circumferentially distributed carbide cutting tips. The welding quality between the cutting tips and the base directly affects the saw blade's cutting performance and service life. During the welding process, precisely fixing the grinding saw blade and ensuring the relative positional accuracy of the cutting tips and the base has always been a key focus for those skilled in the art.

[0003] However, most existing tooling uses a multi-bolt fastening method, which takes 3-5 minutes to clamp each time and requires high skill from the operator.

[0004] The purpose of this invention is to provide an auxiliary tooling for grinding wheel saw blades, which can overcome the shortcomings of the prior art, achieve high-precision positioning and quick clamping of grinding wheel saw blades, and has good structural rigidity and versatility. Summary of the Invention

[0005] To address the aforementioned problems, this utility model discloses an auxiliary tooling for grinding wheel saw blades.

[0006] To achieve the above objectives, this application discloses an auxiliary tooling for a grinding wheel saw blade, including a pressure body and a base. The pressure body is aligned with the central recess of the grinding wheel saw blade. The base has a placement hole for alignment with the center of the grinding wheel. During the welding operation of the blade head to the base, the grinding wheel saw blade is pressed onto the base by the pressure body to fix the grinding wheel saw blade.

[0007] A rotating cylinder is rotatably mounted on the base. A support rod is mounted on the top of the rotating cylinder. A pressure plate is slidably mounted on the support rod along its vertical direction. A tension spring is connected between the bottom end of the pressure plate and the support rod. The side of the pressure plate is used to press against the saw blade of the grinding wheel to be processed.

[0008] The side of the rotating drum is provided with a worm gear transmission mechanism, which drives the rotating drum to rotate the pressure plate to the corresponding pressing position.

[0009] A positioning post is provided in the middle of the bottom of the pressure body, which is used to align and cooperate with the center hole on the base located below the grinding wheel saw blade.

[0010] The positioning post includes a cylindrical section and a frustum section, wherein the outer diameter of the frustum section gradually decreases from top to bottom. The cylindrical section is used to align with the central hole on the base located below the grinding wheel saw blade, and the frustum section is used to align with the central hole of the grinding wheel saw blade.

[0011] This application utilizes the precise alignment and fit between the pressure body and the central recess of the grinding wheel saw blade, and between the base mounting hole and the center of the grinding wheel. During the blade welding process, this ensures the grinding wheel saw blade is firmly pressed and fixed, effectively preventing displacement and shaking of the saw blade during welding. This improves the stability and reliability of the welding operation, ensures the welding precision between the blade head and the base, and ultimately guarantees the overall quality and performance of the grinding wheel saw blade. The operation is simple and quick, enabling rapid positioning and fixing of the grinding wheel saw blade, improving welding efficiency, and reducing manual adjustment time and labor intensity.

[0015] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0016] Example 1: As shown in Figures 1-2, an auxiliary tooling for a grinding wheel saw blade includes a pressure body 1 and a base 2. The pressure body 1 is aligned with the central recess of the grinding wheel saw blade 3. The base 2 has a placement hole 21 for alignment with the center of the grinding wheel. During the welding operation of the blade head to the base, the grinding wheel saw blade 3 is pressed onto the base 2 by the pressure body 1 to fix the grinding wheel saw blade.

[0017] In this embodiment, the auxiliary tooling consists of a pressure body 1 and a base 2. The pressure body 1 fits into the central recess of the grinding wheel saw blade 3, and the placement hole 21 on the base 2 is aligned with the center of the grinding wheel. During welding, the pressure body 1 presses the disc base of the grinding wheel saw blade 3 firmly onto the base 2, and then the saw teeth to be welded are placed one by one on the disc base to ensure that the disc base of the grinding wheel saw blade remains stable during the welding process, avoids welding position deviation due to shaking, and ensures welding quality.

[0018] A rotating cylinder 4 is rotatably mounted on the base 2. A support rod 41 is mounted on the top of the rotating cylinder 4. A pressure plate 5 is slidably mounted on the support rod 41 along its vertical direction. A tension spring 6 is connected between the bottom end of the pressure plate 5 and the support rod 41. The side of the pressure plate 5 is used to press against the saw blade 3 of the grinding wheel to be processed.

[0019] The rotating drum 4 mounted on the base 2 is rotatable, and the support rod 41 at the top of the rotating drum 4 is vertically set. The pressure plate 5 can slide up and down along the support rod 41, and a tension spring 6 connects the pressure plate 5 and the support rod 41. When it is necessary to fix the grinding wheel saw blade 3, the side of the pressure plate 5 is pressed tightly against the saw teeth to be welded on the grinding wheel saw blade 3 under the tension of the tension spring 6, providing additional downward pressure to the saw teeth of the grinding wheel saw blade and further enhancing the fixing effect.

[0020] A worm gear transmission mechanism 7 is provided on the side of the rotating drum 4. This mechanism drives the rotating drum 4 to rotate the pressure plate 5 to the corresponding pressing position. By operating the worm gear transmission mechanism 7, the rotating drum 4 can be precisely driven to rotate, thereby causing the pressure plate 5 to rotate to the appropriate pressing position. The worm gear transmission has the characteristics of a large transmission ratio and strong self-locking, making the position adjustment of the pressure plate 5 precise and stable. The position of the pressure plate 5 can be flexibly adjusted according to different specifications and shapes of grinding wheel saw blades.

[0021] Example 2: As shown in Figure 3, a positioning post 11 is provided in the middle of the bottom of the pressure body 1. The positioning post 11 is used to align and cooperate with the center hole 22 on the base 2 located below the grinding wheel saw blade 3. By cooperating with the center hole 22 on the base 2, the positioning post 11 ensures that the pressure body 1 and the base 2 are aligned in the vertical direction, preventing uneven pressure caused by the offset of the pressure body 1.

[0022] The positioning post 11 includes a cylindrical section 111 and a frustum section 112. The outer diameter of the frustum section 112 gradually decreases from top to bottom. The cylindrical section 111 is used to align with the center hole 22 on the base 2 located below the grinding wheel saw blade 3, and the frustum section 112 is used to align with the center hole 23 of the grinding wheel saw blade 3. The frustum section 112 forms a conical structure that is larger at the top and smaller at the bottom, and has a self-centering function. When the pressure body 1 falls, even if there is an initial position deviation, the frustum section 112 can guide the center hole 23 of the grinding wheel saw blade 3 to automatically align through the inclined surface.

[0023] During operation, when the pressure body 1 falls, the cylindrical section 111 first inserts into the center hole 22 of the base to determine the approximate position of the pressure body 1. The outer cylindrical surface of the cylindrical section 111 provides axial guidance for the subsequent insertion of the frustum section 112. After the conical surface of the frustum section 112 contacts the center hole 23 of the grinding wheel saw blade 3, the radial deviation is automatically corrected by the inclined plane component force.

[0024] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
