Description

Technical Field

[0001] The invention relates to the field of mechanical manufacturing, and in particular to a processing method for a part with multiple slopes and no vertical surface as a reference surface. Background Art

[0002] In the process of machining mechanical parts, especially in the process of manufacturing mold parts, some parts with multiple inclined surfaces and no vertical surface as a reference are often difficult to machine. They need to be clamped and machined in a five-axis machining center. During this period, the five-axis machining center cannot be turned over or the reference cannot be changed. However, sometimes due to limited space, the five-axis machining center cannot meet the machining requirements. At this time, a special fixture needs to be made, which is costly. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a method for machining multi-bevel parts by using a three-axis machining center to replace a five-axis machining center and reduce manufacturing costs.

[0004] The technical solution of the present invention is

[0005] A method for machining a multi-bevel part using a three-axis machining center, comprising:

[0006] First, use the three-axis machining center to process the multi-slope side of the part, select the process block and stick it on the multi-slope surface of the part, and use milling to change the outline of the part and the process block on this side into a shape that can be aligned by the three-axis machining center; then turn the bonded part and the process block over, and use the three-axis machining center to process the other side of the part; finally, remove the bonded process block to obtain the processed part.

[0007] Specifically include:

[0008] Step 1: Processing mesh grooves on the surface of the aluminum process block;

[0009] Step 2: Clamp the unprocessed cuboid of the part onto the three-axis machining center, and process all the inclined surfaces that can be processed by this clamping;

[0010] Step 3: Fill the groove of the process block with glue, stick it firmly on the milled slope, and wait;

[0011] Step 4: After the glue has dried, mill the process block to change the contour of the part on this side combined with the process block into a shape that can be aligned by the three-axis machining center;

[0012] Step 5: Fix the reverse side of the part and perform additional processing on the unprocessed surface;

[0013] Step 6: Remove the bonded process blocks to obtain the processed parts.

[0014] The process block is made of aluminum, and the material selected is 6061.

[0015] Step 6: Remove the bonded process block by knocking it off or heating it.

[0016] In step 1, the mesh groove is an equilateral triangle, the side length of the mesh groove is 2 mm, and the groove spacing is 8 mm.

[0017] Step 4 The three-axis machining center can align in the following forms:

[0018] The process block and the processed parts as a whole form two base surfaces which are perpendicular to each other and respectively perpendicular to the ground.

[0022] The method for machining multi-bevel parts using a three-axis machining center provided by the invention has the main advantage of using a three-axis machining center to replace a five-axis machining center for machining, thereby reducing machining costs.

[0023] By testing aluminum process blocks (6061) and comparing other material process blocks (steel, copper), the following points are found:

[0024] Aluminum has a lower density, which reduces the labor intensity of workers during operation.

[0025] 6061 has good machinability, which can improve machining efficiency and reduce machining costs.

[0026] 6061 material has good corrosion resistance and can be stored for a long time.

[0027] Through comparative tests, it was found that the bonding is most reliable when the wire groove width is an equilateral triangle of 2mm. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present invention discloses a method for machining multi-bevel parts using a three-axis machining center. The basic idea is to stick a process block on the surface of the multi-bevel part that is not conducive to alignment, so that its outer contour is restored to a rectangle or other shape that is easy to align, and then remove the process block after the machining is completed. Specifically, it includes:

[0033] First, use the three-axis machining center to process the multi-slope side of the part, select the process block and stick it on the multi-slope surface of the part, and use milling to change the outline of the part and the process block on this side into a shape that can be aligned by the three-axis machining center; then turn the bonded part and the process block over, and use the three-axis machining center to process the other side of the part; finally, remove the bonded process block to obtain the processed part.

[0038] Step 3: Clamp the unprocessed cuboid of the part onto the three-axis machining center, and process all the inclined surfaces that can be processed by this clamping;

[0039] Step 4: Fill the groove of the process block with glue, stand firmly on the milled slope, and wait;

[0041] Step 6. Fix the parts with glue on the back or use a vise to clamp the parts, but do not touch the process block (to prevent the process block from being clamped off), and perform additional processing on the unprocessed surface.
