Description

Technical Field

[0001] This utility model relates to the field of blade grinding technology, and in particular to a multi-angle blade grinding fixture. Background Technology

[0002] like Figure 4 As shown, a blade to be sharpened is generally rectangular in shape, with a bevel 30 formed at one end. This bevel 30 creates a wedge-shaped structure on one side of the blade. The length direction of the bevel 30 is inclined to the length direction of the blade. Multiple arc grooves 31 are formed on the outer end of the other side of the blade, and an inner groove 32 is formed on the other side, communicating with the arc grooves 31. In processing a surface with two angles, the bevel 30 of the blade is usually sharpened one by one. However, this method is inefficient and also suffers from difficulty in controlling the sharpening effect. Utility Model Content

[0003] This utility model provides a multi-angle blade grinding fixture to overcome the shortcomings of the prior art, improve the grinding efficiency of blades, and control the grinding accuracy, thus having strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A multi-angle cutting tool grinding fixture includes a disc with multiple placement holes arranged in a circumferential array on the disc. These placement holes are inclined, with an angle between their depth direction and the axial direction of the disc, and both holes face the same direction. A placement plate is placed within each placement hole, and a groove is formed on the placement plate. The bottom of the groove is inclined, and an angle is formed between the length direction of the groove bottom and the length direction of the placement plate. The inclination of the placement holes facilitates grinding the beveled surfaces of the cutting tools by the grinding disc. The placement plate supports the inner end of the cutting tool, and the inclined surface at the bottom of the groove allows the placed cutting tool to be in an inclined position, facilitating grinding at another inclined angle. This method allows for simultaneous grinding of multiple cutting tool bevels, and the strict constraint on the cutting tools during grinding improves grinding accuracy.

[0006] Furthermore, the length direction of the placement hole is set along the radial direction of the disk to facilitate the placement of the blade and improve the utilization rate of the disk space.

[0007] Furthermore, the bottom of the groove is provided with clearance grooves at both ends to ensure that the placement plate will not crack during placement and to avoid the edge of the blade.

[0008] Furthermore, the clearance groove has a circular structure to prevent the placement plate from cracking at the corner of the groove.

[0009] Furthermore, one side of the placement hole is shaped and notched to facilitate the discharge of grinding debris and avoid secondary grinding of the blade.

[0010] Furthermore, the notch has a semi-circular structure, and a semi-circular wedge-shaped rod can be inserted into the semi-circular structure to fix the blade and the placement plate.

[0011] Furthermore, the angle formed between the depth direction of the placement hole and the axis of the disk is less than a degree.

[0012] Furthermore, the angle between the length direction of the groove bottom and the length direction of the placement plate is an acute angle.

[0013] Furthermore, a central hole is coaxially provided on the disk to facilitate the discharge of grinding debris.

[0014] Furthermore, the disk has multiple mounting holes arranged in a circular array to facilitate the installation of the disk.

[0015] The advantages of the above technical solution are:

[0016] This invention can perform grinding of multiple blades simultaneously while ensuring grinding precision, making it highly practical. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0019] Figure 2 A three-dimensional structural diagram of the disk is shown.

[0021] Figure 4 A three-dimensional structural diagram of the blade is shown. Detailed Implementation

[0022] like Figures 1-4As shown, a multi-angle cutting tool grinding fixture includes a disc 1. A central hole 10 is coaxially formed on the disc 1. Multiple mounting holes 11 are arranged in a circular array on the disc 1. Multiple placement holes 12 are arranged in a circumferential array on the disc 1. The placement holes 12 are inclined, and there is an angle between the depth direction of the placement holes 12 and the axial direction of the disc 1. The placement holes 12 face the same direction, and their length direction is arranged radially along the disc 1. A notch 13 is formed on one side of each placement hole 12. The notch 13 has a semi-circular structure. Specifically, the angle formed between the depth direction of the placement hole 12 and the axial direction of the disc 1 is less than 45 degrees.

[0023] A placement plate 2 is provided inside the placement hole 12. A groove 20 is formed on the placement plate 2. The bottom of the groove 20 is inclined, and there is an angle between the length direction of the bottom of the groove 20 and the length direction of the placement plate 2. The angle between the length direction of the bottom of the groove 20 and the length direction of the placement plate 2 is an acute angle. A clearance groove 22 is formed at both ends of the bottom of the groove 20. The clearance groove 22 has a circular structure.

[0024] In this embodiment, during operation, the operator places each blade 3 into the groove 20 of the placement plate 2, with the side to be ground facing upwards. Next, the operator places the placement plate 2 and the blade 3 into the placement hole 12, with the side carrying the arc groove 31 facing downwards. Then, a wedge-shaped pin is inserted through one side of the notch 13 to fix the blade 3 and the placement plate 2. After fixing, the disc 1 is installed on the grinding device, with the side of the disc 1 exposed above the grinding wheel. The automatic control system on the grinding table controls the feed of the grinding wheel and completes the grinding operation on the inclined surface 30 of the blade 3.

[0025] When fixing the placement plate 2 and the blade 3, the size of the placement hole 12 can be machined to match the size of the placement plate 2 and the blade 3, so as to fix the blade and the placement plate 2. In addition, the size of the inner end of the placement hole 12 needs to be smaller than the size of the placement plate 2 to prevent the placement plate 2 from moving.

[0026] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
