Description

Technical Field

[0001] This utility model belongs to the technical field of tool chamfering devices, and in particular relates to a chamfering device for precision tool machining. Background Technology

[0002] Cutting tools are tools used for cutting and machining in mechanical manufacturing. Most cutting tools are machine-made, but some are hand-made. Since cutting tools used in mechanical manufacturing are mainly used for cutting metal materials, cutting tools for cutting wood are called woodworking tools. There is also a special type of cutting tool used for geological exploration, well drilling, and mining, which is called mining tools.

[0003] Some small cutting tool heads require chamfering of a few millimeters to enhance tool strength. Typical chamfering devices can only produce a fixed chamfer angle and width, and cannot fine-tune these angles and widths as needed. This is because the height of the chamfering disc and the angle of the tool grinding table are fixed, making fine-tuning relatively difficult. Utility Model Content

[0004] The purpose of this utility model is to provide a chamfering device for precision tool processing. The chamfering angle of the tool grinding table can be adjusted by finely adjusting the tilt angle on the grinding table frame, and the grinding thickness can be adjusted by finely adjusting the height of the adjustable square column. This solves the problems of existing chamfering devices where the height position of the grinding disc and the tilt angle of the tool grinding table are fixed, making fine adjustment difficult.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a chamfering device for precision cutting tool processing, comprising an operating table, a tool grinding table, a grinding table frame, a grinding assembly, and a distance adjustment assembly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-6This utility model relates to a chamfering device for precision cutting tool processing, comprising an operating table 1, a tool grinding table 2, a grinding table frame 3, a grinding assembly, and a distance adjustment assembly. The operating table 1 has a flat ramp and an inclined ramp. The tool grinding table 2 is mounted on the grinding table frame 3, and the bottom end of the grinding table frame 3 is fixed to the flat ramp. The inclined ramp has a square hole. The distance adjustment assembly includes a distance adjustment square post 4, a distance adjustment bolt rod 9, and a rotating assembly. The bottom of the distance adjustment square post 4 is inserted into the square hole. The distance adjustment bolt rod... A spiral is inserted from the bottom center of the adjustable column 4. A rotating shaft 91 is connected to the adjustable bolt rod 9. A bearing is fitted on the rotating shaft 91 and embedded in the operating table 1. The adjustable assembly is used to adjust the rotation of the rotating shaft 91. The grinding assembly includes a grinding disc 8 and a grinding motor 81. The grinding disc 8 is fitted on the rotating shaft of the grinding motor 81. The grinding motor 81 is embedded in the top of the adjustable column 4. The tool grinding table 2 is located at the upper edge of the grinding disc 8.

[0024] Before grinding the tool, the chamfering degree to be ground is adjusted. The tool grinding table 2 on the grinding table 3 can be finely tilted to adjust the chamfering angle. The width of the chamfer to be ground is the grinding thickness. The rotating shaft 91 is adjusted by adjusting the distance component. The rotating distance bolt 9 can slightly push the distance adjustment column 4 up and down (adjustment of no more than 3mm in height). The grinding thickness is adjusted by changing the distance between the grinding disc and the tool grinding table 2.

[0025] The grinding disc has a circular groove. When water drips into the circular groove, it is not instantly flung out, but slides along the inner wall of the circular groove to the surface of the grinding disc.

[0026] The tool grinding table 2 is provided with an inclined platform 21. A grinding groove 22 is left between the inclined platform 21 and the bottom of the front side wall of the tool grinding table 2. The two side walls of the tool grinding table 2 are symmetrically provided with mounting shafts 23 near the rear end. The two side walls of the tool grinding table 2 are symmetrically provided with angle adjustment rods 24 near the front end.

[0027] The cutting tool is manually pushed into the grinding groove 22, so that the grinding edge protrudes from the grinding groove 22 and contacts the grinding disc 8, thus achieving grinding. Because the tilting table 21 is tilted (e.g., ...), Figure 3 and 4 The edge will be slightly exposed by a few millimeters, and the distance between the tool grinding table 2 and the grinding disc is also small. This achieves the grinding of the edge to form a chamfer.

[0028] The grinding table 3 includes a U-shaped frame and a fixing plate connected to both ends of the U-shaped frame. The U-shaped frame has pivot holes 31 on both side walls near the fixing plate. The U-shaped frame has two symmetrical arc-shaped slots 32 on both side walls near the middle plate. Two bolt plates 33 with corresponding upper and lower dimensions are provided on the outer side wall of the U-shaped frame of each arc-shaped slot 32. Bolts 30 are screwed on the bolt plates 33. The two mounting shafts 23 are respectively installed in the two shaft holes 31, and the two angle adjustment rods 24 are respectively inserted into the two arc-shaped strip holes 32. The ends of the angle adjustment rods 24 are provided with pointers 241, and the rotation angle can be read by setting a scale on the outer wall of the U-shaped frame.

[0029] The tool grinding table 2 can rotate up and down along the pivot hole 31. The angle adjustment rod 24 moves up and down in an arc shape within the two arc-shaped slots 32. In order to limit the position, two bolts 30 at the same position of the arc-shaped slots 32 are rotated to clamp the position of the angle adjustment rod 24, so as to fix the position after the angle is adjusted.

[0030] The top of the adjustable column 4 is provided with a U-shaped opening 41, and a motor slot 42 is provided at the center of the top of the adjustable column 4. The slot of the motor slot 42 is surrounded by a rim 43. A drip pipe insert plate 44 is provided on the rear side of the top of the adjustable column 4, and a drip pipe 5 is inserted into the drip pipe insert plate 44.

[0031] The U-shaped opening 41 allows the splashed water to flow smoothly downwards, while the surrounding edge 43 prevents small amounts of water from overflowing into the motor slot 42. The grinding motor is waterproof, but water inflow should still be minimized. The drip pipe 5 is positioned precisely on the surface of the grinding disc to drip or allow a small flow of water to flow down, facilitating rapid heat dissipation during grinding.

[0032] The adjustable distance assembly includes a large conical gear disk 6, a small conical gear disk 71, and a knob 7. The large conical gear disk 6 is sleeved on the end of the rotating shaft 91, and the knob 7 is installed on the small conical gear disk 71. The large conical gear disk 6 meshes with the small conical gear disk 71.

[0033] The large conical gear 6 rotates only once when the small conical gear 6 rotates multiple times, so that the rotation accuracy of the large conical gear 6 can be manually adjusted. A scale can be provided on the side wall of the adjustment column 4 so that the size of the protruding scale can be seen to identify the extension height.

[0034] The diameter of the large conical gear disk 6 is 5-8 times that of the small conical gear disk 71. One rotation of the large conical gear disk 6 achieves a displacement of 1-2mm in the pitch adjustment column 4, thus enabling precise control of the pitch adjustment.
