Description

Technical Field

[0001] The utility model relates to the technical field of tool processing, in particular to a milling cutter edge shaping and grinding device. Background Art

[0002] As an indispensable tool in industrial processing, the ingenuity of the design and use of milling cutters directly affects the processing efficiency and product quality; a milling cutter with excellent performance can not only improve work efficiency, but also improve the surface quality of the workpiece and reduce the need for subsequent processing. During the processing of milling cutters, the step of blade grinding is a complex and delicate process. Various problems may occur during the grinding process, which will affect the performance and service life of the milling cutter.

[0003] When a milling cutter is ground using a grinding device, metal chips generated by grinding are easy to splash and then hit the cutting edge and end face of the milling cutter at other positions. The impact force of the metal chips can easily cause scratches on the cutting edge and end face of the milling cutter, resulting in low appearance accuracy of the milling cutter. At the same time, the splashed metal chips are easy to fly into the environment, resulting in a harsh processing environment and inconvenient for recycling the metal chips. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a milling cutter edge shaping grinding device to solve the problem that metal debris generated by grinding is easy to splash and easily cause scratches when impacting the milling cutter edge and end face.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a milling cutter edge shaping grinding device, including a rotating grinding disc and a milling cutter clamping unit, and also including:

[0006] A protective suction hood vertically wraps the grinding disc near the milling cutter, and the protective suction hood is provided with a processing hole for the milling cutter to penetrate and contact the grinding disc;

[0007] A suction pump is connected to the protective suction hood.

[0008] The technical principle of the utility model is as follows: when grinding the milling cutter, the milling cutter clamping unit clamps the milling cutter, and the grinding part of the milling cutter passes through the processing hole of the protective suction hood and is opposite to the grinding disk, and the rotating grinding disk grinds the milling cutter; at the same time, the suction pump is started, and the negative pressure generated by the suction pump can quickly suck the metal debris splashed in the protective suction hood, reducing the probability of the metal debris splashing and rebounding multiple times in the protective suction hood, and can reduce the probability of the cutting edge and end face of the milling cutter being scratched; it is also convenient to recycle and collect the metal debris at the suction pump.

[0009] Furthermore, a plurality of suction holes are arranged in the protective suction cover on one side close to the processing hole, a suction cavity connected with the suction pump is arranged in the protective suction cover on one side close to the processing hole, and the suction cavity is connected with the suction holes.

[0010] Through the above arrangement, the negative pressure of the suction pump can be transmitted to the suction chamber and the suction hole, and most of the splashing metal debris formed by the milling cutter during the grinding process can enter the suction hole and the suction chamber, further directly reducing the amount of metal debris rebounding on the inner wall of the protective suction hood.

[0011] Furthermore, a suction pipe is connected between the suction pump and the protective suction hood, and a filtering and collecting pipe portion is provided at the middle of the suction pipe.

[0012] Through the above arrangement, the filtering and collecting pipe part on the suction pipe can filter and collect metal debris in the suction process, so that the metal debris can be quickly filtered and recovered, making the recycling and reuse of the metal debris more convenient, and at the same time preventing a large amount of metal debris from entering the suction pump.

[0013] Further, the suction tube comprises:

[0014] A first connecting pipe portion, the upper end of which is fixedly connected to the middle portion of the lowermost side of the protective suction hood and communicates with the suction chamber and the middle portion of the lowermost side of the protective suction hood, and the lower end of which is detachably connected to the filter collection pipe portion;

[0015] The second connecting pipe part has one end connected to the suction pump and the other end detachably connected to an end of the filtering and collecting pipe part away from the first connecting pipe part.

[0016] Through the above arrangement, the first connecting pipe portion and the second connecting pipe portion can cooperate with the filtering and collecting pipe portion to realize the recovery of metal debris; at the same time, the first connecting pipe portion can be accurately connected with the protective suction hood and the suction chamber to facilitate the transmission of negative pressure.

[0017] Further, the filter collection tube comprises:

[0018] A pipe body, one end of which is threadedly connected to the first connecting pipe portion, and the other end of which is threadedly connected to the second connecting pipe portion;

[0019] A first filter screen is coaxially fixedly mounted on the pipe body near the first connecting pipe portion;

[0020] The second filter screen blocks the metal debris. The second filter screen is coaxially fixedly installed on the pipe body close to the second connecting pipe part. The mesh number of the first filter screen is smaller than the mesh number of the second filter screen.

[0021] Through the above arrangement, the tube body can cooperate with the first filter screen and the second filter screen, so that metal debris can pass through the first filter screen and remain between the first filter screen and the second filter screen, which is convenient for collecting metal debris.

[0022] Furthermore, the tube body is coaxially and vertically arranged between the first connecting tube portion and the second connecting tube portion.

[0023] Through the above arrangement, the pipe body can be more accurately and stably connected with the first connecting pipe part and the second connecting pipe part.

[0024] Furthermore, the circumferential edge of the second filter screen extends toward the inner wall of the tube body close to one end of the first filter screen, and the edge of the second filter screen is fixedly connected to the edge of the tube body and the first filter screen.

[0025] Through the above arrangement, the first filter screen and the second filter screen can be more stably installed in the tube body, so that the filtering and collecting effect can be more easily and stably exerted. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] This embodiment is basically Figure 1 , Figure 2 and Figure 3As shown, an embodiment of the utility model proposes a milling cutter edge forming grinding device, comprising a rotating grinding disc 10, a milling cutter clamping unit, a protective suction hood 20, a suction pump 30 and a suction pipe located between the suction pump 30 and the protective suction hood 20, a filtering and collecting pipe portion is provided at the middle of the suction pipe; the protective suction hood 20 is annular, and the protective suction hood 20 vertically wraps the side of the grinding disc 10 close to the milling cutter, a flange 201 is provided on the inner ring of the protective suction hood 20, and a processing hole 21 is provided on the protective suction hood 20 for the milling cutter to penetrate and contact the grinding disc 10.

[0032] like Figure 1-3 As shown, a plurality of suction holes 202 are provided on one side of the protective suction hood 20 close to the processing hole 21 , a suction chamber 203 connected to the suction pump 30 is provided on one side of the protective suction hood 20 close to the processing hole 21 , and the suction chamber 203 is connected to the suction holes 202 .

[0033] like Figure 1 and Figure 3 As shown, the suction pipe includes a first connecting pipe portion 301 and an "L"-shaped second connecting pipe portion 302, and the filtering collection pipe includes a pipe body 303, a first filter screen 304 and a second filter screen 305 for blocking metal debris; the upper end of the first connecting pipe portion 301 is fixedly connected to the middle part of the lowermost side of the protective suction hood 20 and is connected to the suction chamber 203 and the middle part of the lowermost side of the protective suction hood 20; one end of the second connecting pipe portion 302 is connected to the suction pump 30; the pipe body 303 is vertically arranged, and the pipe body 303 is coaxially vertically arranged between the first connecting pipe portion 301 and the second connecting pipe portion 302; the upper end of the pipe body 303 is threadedly connected to the lower end of the first connecting pipe portion 301, and the lower end of the pipe body 303 is threadedly connected to the upper end of the second connecting pipe portion 302.

[0034] At the same time, if Figure 3 As shown, the first filter screen 304 is coaxially fixedly installed on the tube body 303 near the first connecting tube portion 301; the second filter screen 305 is coaxially fixedly installed on the tube body 303 near the second connecting tube portion 302, and the mesh number of the first filter screen 304 is smaller than the mesh number of the second filter screen 305; the circumferential edge of the second filter screen 305 extends toward the inner wall of the tube body 303 near one end of the first filter screen 304, and the edge of the second filter screen 305 is fixedly bonded to the edges of the tube body 303 and the first filter screen 304.

[0035] When a milling cutter blade shaping grinding device in this embodiment is in use, the milling cutter clamping unit clamps the milling cutter, and the grinding part of the milling cutter passes through the processing hole 21 of the protective suction hood 20 and is opposite to the grinding disk 10. At this time, the motor that drives the grinding disk 10 to rotate and the suction pump 30 are turned on, and the rotating grinding disk 10 grinds the milling cutter.

[0036] During the grinding process, the negative pressure generated by the suction pump 30 is transmitted to the protective suction hood 20 through the second connecting pipe part 302, the pipe body 303 and the first connecting pipe part 301 in turn. At this time, the naturally splashed metal debris will be blocked by the protective suction hood 20 and the flange 201 on the inner wall of the protective suction hood 20, and then fall to the bottom of the protective suction hood 20. This part of the metal debris automatically enters the first connecting pipe part 301; at the same time, a part of the negative pressure is transmitted to the suction hole 202 through the suction chamber 203, so that most of the splashed metal debris generated by the milling cutter during the grinding process can enter the suction hole 202 and the suction chamber 203. 03, the rebound amount of metal debris on the inner wall of the protective suction hood 20 is directly reduced, and the probability of the milling cutter's blade and end surface being scratched is reduced; this part of the metal debris also enters the first connecting pipe part 301 through the suction chamber 203, and the metal debris entering the first connecting pipe part 301 is continuously subjected to the negative pressure, and then enters the tube body 303.

[0037] When a large amount of metal debris is collected between the first filter screen 304 and the second filter screen 305 of the tube body 303, the tube body 303 between the first connecting pipe part 301 and the second connecting pipe part 302 is removed by screwing, and the metal debris in the first filter screen 304 and the second filter screen 305 are taken out in batches, and then the tube body 303 is screwed back and installed between the first connecting pipe part 301 and the second connecting pipe part 302, so that the metal debris can be continuously filtered and recovered, making the recycling and reuse of the metal debris more convenient and simple.
