Description
Technical Field
[0001] The utility model relates to the technical field of milling cutters, in particular to a reticulated plane milling cutter. Background Art
[0002] Many shell parts are two-half butt joint structures. In order to prevent oil, water or air leakage from the joint surface, the joint surface is generally sealed with sealants, gaskets and other structures. For example, the gearbox housing and rear axle housing of agricultural machinery. When processing the joint surface of the two halves of the shell, it is cut into a plane by a milling cutter and meets the surface roughness requirements. However, when combined, the joint surfaces of the two halves of the shell are squeezed against each other by the torque of the bolts, so that most of the sealant is squeezed out. If too much sealant is squeezed out, it is easy to have a partial lack of sealant on the joint surface, causing leakage.
[0003] In response to this, shells with mesh surfaces have appeared on the market. When combined, the mesh can store some sealant, thereby preventing the local lack of sealant on the joint surface and improving the sealing. However, when processing this type of joint surface, it is necessary to first use an ordinary milling cutter to cut the required roughness, and then use a mesh milling cutter to cut the mesh shape; or install the roughing cutter and the mesh cutter together on the milling cutter disc, and cut the mesh surface while roughing, and then use the finishing cutter disc to process the required roughness. Two processings are required to process the mesh surface and ensure the surface roughness, which is a large workload, low efficiency, and high processing cost. Utility Model Content
[0004] The technical problem to be solved by the utility model is: how to realize one-time processing of the reticulated surface and ensure the surface roughness at the same time.
[0005] The technical solution of the utility model to solve the above technical problems is as follows:
[0006] The utility model provides a reticulated surface milling cutter, comprising a milling cutter disc, wherein one end of the milling cutter disc is provided with a plurality of blades distributed along the circumference, and the blade edges of the blades all protrude from the end face of the milling cutter disc; the plurality of blades comprise a wiping blade, a reticulated blade and a plurality of common blades; the blade edge of the wiping blade protrudes from the blade edge of the common blade, and the blade edge of the reticulated blade protrudes from the blade edge of the wiping blade; the cutting diameter of the wiping blade is not greater than the cutting diameter of the common blade, and the cutting diameter of the reticulated blade is smaller than the cutting diameter of the wiping blade.
[0007] The beneficial effects of the utility model are:
[0008] By adopting the utility model, a common blade, a finishing blade and a textured blade are arranged on the milling cutter disc at the same time, and the cutting diameters thereof are controlled to decrease in sequence, so that the common blade first cuts off the processing allowance, followed by finishing with the finishing blade, and finally the textured blade processes the mesh marks, and the finishing blade finishes and cleans the textured burrs; thus, one-time processing of the textured surface is realized, processing efficiency is improved, and the surface roughness of the processed surface is guaranteed.

When the ordinary blade works at the maximum feed rate of its own cutting capacity, the wiper blade can still fully smooth the milling surface left by the ordinary blade to ensure the surface roughness.
[0012] Furthermore, the blade length of the wiping blade along the radial direction of the milling cutter disc is more than twice the blade length of the ordinary blade along the radial direction of the milling cutter disc.

The wiper blade can fully smooth the milling surface left by the ordinary blade to ensure surface roughness.
[0014] Furthermore, the cutting diameter of the wiping blade is equal to the cutting diameter of the common blade; and the plurality of blades are evenly distributed around the axis of the milling cutter disc.
[0015] Multiple blades are evenly distributed, so that the feed amount of each blade along the feed direction is consistent, avoiding a sharp increase in the impact force on an ordinary blade adjacent to the wiper blade, and the surface roughness is stable; at the same time, when the wiper blade turns to the rear side of the cutting direction, it can still polish and clean the cutting surface left by the ordinary blade, thereby improving the surface processing quality.
[0016] Furthermore, the cutting diameters of the wiping blade and the ordinary blade are both 125 mm, and the cutting diameter of the anilox blade is 116 mm; the blade length of the wiping blade along the radial direction of the milling cutter disc is 8 mm, and the blade length of the ordinary blade along the radial direction of the milling cutter disc is 3.6 mm.
[0017] The processing range of the polishing blade can completely cover the milling plane left by the ordinary blade and the textured surface left by the textured blade, ensuring the surface roughness after processing, and there will be no local polishing defects, and the processing quality is good.
[0018] Furthermore, the blade edge of the wiper blade protrudes 0.02 mm more than the blade edge of a common blade.
[0019] It is convenient to smooth the milling surface left by ordinary blades and improve the surface roughness.
[0020] Furthermore, the blade edge of the anilox blade protrudes 0.02 mm to 0.03 mm more than the blade edge of the wiper blade.
[0021] It is convenient to leave a reticulate pattern on the cutting surface to prevent the reticulated surface from being eliminated by the polishing blade.
[0022] Furthermore, it also includes a reticulated knife seat, which is fixedly connected to the milling cutter disc by installing screws, and the reticulated blade is fixedly connected to the reticulated knife seat by blade screws.
[0023] The anilox blade can be disassembled along with the anilox blade holder, making it easy to replace anilox blades of different specifications, thereby processing aniloxes of different sizes.
[0024] Furthermore, a fine-tuning screw is provided at the upper end of the anilox cutter seat, and the upper end of the fine-tuning screw abuts against the milling cutter disc.
[0025] The height of the edge of the anilox blade protruding more than the edge of the polishing blade can be adjusted by turning the knob fine-tuning screw, and the preferred adjustment range is 0.02mm to 0.03mm, so that the depth of the processed anilox can be adjusted, with good flexibility.
[0026] Furthermore, it also includes a milling cutter handle, which is located at the middle of one end of the milling cutter disc away from the blade, and the milling cutter disc is fixed to the milling cutter handle by connecting bolts passing through the milling cutter disc.
[0027] It can be connected to the cutter holder on the milling machine through the milling cutter handle, which is easy to install. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0039] This utility model refers to Figure 1-5 .
[0040] The utility model provides a reticulated surface milling cutter, comprising a milling cutter disc 1, wherein one end of the milling cutter disc 1 is provided with a plurality of blades distributed along the circumference, wherein the blade edges all protrude from the end surface of the milling cutter disc 1; the plurality of blades comprises a wiper blade X, a reticulated blade W and a plurality of common blades P; the blade edge of the wiper blade X protrudes from the blade edge of the common blade P, and the blade edge of the reticulated blade W protrudes from the blade edge of the wiper blade X; the cutting diameter Φ of the wiper blade X is not greater than the cutting diameter Φ of the common blade P, and the cutting diameter Φ of the reticulated blade W is smaller than the cutting diameter Φ of the wiper blade X.
[0041] principle:
[0042] The blade protrusion is the axial protrusion pointing to the milling cutter disc 1. The cutting diameter Φ refers to the outer diameter of the circular contour that the blade of the blade rotates when the milling cutter disc 1 rotates (that is, the diameter of the circular contour that the blade rotates along the radial outer corner of the milling cutter disc 1), which is the maximum cutting distance of the blade; therefore, the cutting diameter Φ defines the positional relationship of the blade edge (along the radial outer side of the milling cutter disc 1). The ordinary blade P, also known as the roughing blade, is mainly used to cut off most of the machining allowance.
[0043] When the milling cutter rotates, the cutting diameter Φ of the ordinary blade P is the largest. The plurality of ordinary blades P first contact the cutting surface along the feed direction, remove most of the machining allowance, and preliminarily improve the surface roughness; then, the wiping blade X performs cutting, and the blade edge of the wiping blade X slightly protrudes from the blade edge of the ordinary blade P, and the milling plane left by the ordinary blade P is flattened to the required surface roughness; finally, the anilox blade W performs cutting, leaving a mesh mark (such as Figure 6-7The anilox blade W will generate burrs during the cutting process. The cutting diameter Φ of the anilox blade W is smaller than the cutting diameter Φ of the wiper blade X, that is, the cutting area of the anilox blade W falls within the processing range of the wiper blade X. When the wiper blade X turns to the rear side of the cutting direction, the burrs generated by the anilox blade W are wiped and cleaned.
[0044] In summary, the utility model adopts the method of simultaneously arranging the common blade P, the finishing blade X and the anilox blade W on the milling cutter disc 1, and controlling the cutting diameters Φ thereof to decrease in sequence, so that the common blade P first cuts off the machining allowance, followed by the finishing blade X for finishing, and finally the anilox blade W for machining the mesh marks, and the finishing blade X for finishing and cleaning the anilox burrs; thus, the one-time machining of the anilox surface is realized, the machining efficiency is improved, and the surface roughness of the machined surface is guaranteed.
[0045] Further, such as Figure 3-4 As shown, the blade length of the wiper blade X along the radial direction of the milling cutter disc 1 is greater than the blade length of the common blade P along the radial direction of the milling cutter disc 1 .
[0046] Note: The blade length corresponds to the width of the circular contour that the blade of the blade rotates when the milling cutter rotates; the blade of the anilox blade W is rounded or pointed, and the contour it rotates is circular, so there is no blade length.
[0047] It is convenient to ensure that the cutting range of the wiper blade X can cover the cutting range of the ordinary blade P. When the ordinary blade P works at the maximum feed rate of its own cutting capacity, the wiper blade X can still fully flatten the milling surface left by the ordinary blade P, ensuring the surface roughness.
[0048] Furthermore, the blade length of the wiper blade X along the radial direction of the milling cutter disc 1 is more than twice the blade length of the common blade P along the radial direction of the milling cutter disc 1 .
[0049] When the cutting diameter Φ of the wiper blade X is close to the cutting diameter Φ of the ordinary blade P, it can ensure that the processing area of the ordinary blade P falls within the processing range of the wiper blade X. The wiper blade X can fully flatten the milling surface left by the ordinary blade P to ensure the surface roughness.
[0050] Furthermore, the cutting diameter Φ of the wiper blade X is equal to the cutting diameter Φ of the common blade P; the plurality of blades are evenly distributed around the axis of the milling cutter disc 1 in a circumferential manner.
[0051] The multiple blades are evenly distributed, so that the feed amount of each blade along the feed direction is consistent, avoiding a sharp increase in the impact force on the ordinary blade P adjacent to the wiper blade X, and the surface roughness is stable; at the same time, when the wiper blade X turns to the rear side of the cutting direction, it can still wipe and clean the cutting surface left by the ordinary blade P, thereby improving the surface processing quality.
[0052] Further, such as Figure 3-5 As shown, the cutting diameter Φ of the wiper blade X and the cutting diameter Φ of the ordinary blade P are both 125 mm, and the cutting diameter Φ of the anilox blade W is 116 mm; the blade length of the wiper blade X along the radial direction of the milling cutter disc 1 is 8 mm, and the blade length of the ordinary blade P along the radial direction of the milling cutter disc 1 is 3.6 mm.
[0053] The processing range of the polishing blade X can completely cover the milling plane left by the ordinary blade P and the textured surface left by the textured blade W, ensuring the surface roughness after processing without the situation of local polishing defects, and the processing quality is good.
[0054] Furthermore, the blade edge of the wiper blade X protrudes 0.02 mm more than the blade edge of the common blade P.
[0055] It is convenient to flatten the milling surface left by the ordinary blade P and improve the surface roughness.
[0056] Furthermore, the blade edge of the anilox blade W protrudes more than the blade edge of the wiper blade X by 0.02 mm to 0.03 mm.
[0057] It is convenient to leave a reticulate pattern on the cutting plane to prevent the reticulated surface from being eliminated by the polishing blade X.
[0058] Further, such as Figure 5 As shown: it also includes a reticulated knife seat 2, which is fixedly connected to the milling cutter disc 1 through mounting screws 3, and the reticulated blade W is fixedly connected to the reticulated knife seat 2 through blade screws 4.
[0059] The anilox blade W can be disassembled along with the anilox blade holder 2, so that the anilox blades W of different specifications can be replaced to process anilox patterns of different sizes.
[0060] Furthermore, a fine-tuning screw 5 is provided at the upper end of the anilox cutter seat 2 , and the upper end of the fine-tuning screw 5 abuts against the milling cutter disc 1 .
[0061] The knob fine-tuning screw 5 can be used to adjust the height of the blade of the anilox blade W protruding from the blade of the polishing blade X. The preferred adjustment range is 0.02 mm to 0.03 mm, so that the depth of the processed anilox can be adjusted, which has good flexibility.
[0062] Further, such as Figure 1 As shown: it also includes a milling cutter handle 6, which is located in the middle of one end of the milling cutter disc 1 away from the blade, and the milling cutter disc 1 is fixed to the milling cutter handle 6 by connecting bolts 7 passing through the milling cutter disc 1.
[0063] The milling cutter handle 6 can be connected to the cutter seat on the milling machine, which is convenient for installation.
