[0002] The stainless steel oil suction well, with dimensions of 1000*700*200, requires beveling, with a 20° bevel required on all sides and at the rounded corners. While beveling straight edges is simple and easy with a planer, beveling a circular area is more challenging. The best method is to use a CNC machining center, but some workshops lack these facilities. To achieve the bevel at the rounded corners, manual grinding is required, resulting in a long production cycle and low precision. Summary of the Invention

[0003] The object of the present invention is to provide a method for processing a groove of a workpiece with a rounded corner, so as to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solution: a method for processing a groove of a workpiece with a rounded corner, comprising the following steps:

[0005] S1. Process the groove on the straight edge of the workpiece on the planer;

[0006] S2, removing the workpiece processed in step S1, and then using a ruler to check the straight edge bevel on the workpiece;

[0007] S3. Set up a machining platform on the rotating surface of the floor-type boring and milling machine;

[0008] S4. Set positioning templates on both sides of the processing platform;

[0009] S5, manufacturing an arc template and installing the arc template on the processing platform;

[0010] S6. Place the workpiece on the processing platform;

[0011] S7, using the positioning die to press the workpiece;

[0012] S8, processing grooves on the rounded corners of the workpiece;

[0013] S9, remove the workpiece processed in step S8, and then use a ruler to check the fillet groove on the workpiece 1;

[0014] S10. Repeat steps S6-S9 three times to perform groove processing on the four fillets on the workpiece.

[0015] Furthermore, in step S2 and step S9, when the workpiece is removed, a high-pressure blower is required to clean the workpiece.

[0016] Furthermore, in step S3, when setting up the processing platform, the rotation center of the processing platform is aligned with the rotation center of the rotating surface of the machine tool.

[0017] Furthermore, in step S3, the processing platform is composed of two base platforms, and the two base platforms are perpendicular to each other, and the two base platforms are parallel to two adjacent straight edges on the workpiece.

[0018] Furthermore, in step S4, when setting the positioning template, it is necessary to first locate the position of the pressure plate in the template to ensure that the pressure plate can press on the straight edge of the workpiece.

[0019] Furthermore, in step S5, the arc mold includes an inner circular ring and an outer circular arc plate, the radius of the inner circular ring is consistent with the radius of the fillet on the workpiece, the inner side surface of the outer circular arc plate is fitted with the outer side surface of the inner circular ring, and the inner circular ring and the outer circular arc plate are both provided with adjustment grooves, the inner circular ring and the outer circular arc plate are connected by bolts, and the bolts connecting the inner circular ring and the outer circular arc plate pass through the adjustment grooves.

[0020] Furthermore, in step S5, when installing the arc template, the center of the arc template needs to be aligned with the rotation center of the processing platform.

[0021] Furthermore, in step S6, before placing the workpiece on the processing platform, the outer arc plate needs to be pulled upward so that the top of the outer arc plate is higher than the inner circular ring.

[0022] Furthermore, in step S7, when the positioning template is used to press the workpiece, it is necessary to allow the pressing plate in the positioning template to press on the straight edge of the workpiece as much as possible.

[0023] Furthermore, in step S8, before the rounded corners are processed on the workpiece, the outer arc plate needs to be pulled downward so that the outer arc plate is lower than the inner ring.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. By using a planer to process the straight edge bevel of the workpiece and a floor-type boring and milling machine to process the rounded corner bevel of the workpiece, the goal of not using a CNC machining center and reducing the processing time is achieved. By manufacturing a corresponding arc template based on the size and shape of the workpiece rounded corner, it can ensure that the workpiece rounded corner is supported when the floor-type boring and milling machine is performing the bevel processing;

[0026] 2. Use the inner circular ring in the arc mold to support the rounded corners of the workpiece, and use the outer arc plate in the arc mold to position the workpiece when placing it. Use an outer arc plate that can be adjusted up and down so that when processing the rounded corners and grooves, the outer arc plate can be moved down and staggered with the processing tool to avoid the outer arc plate interfering with the processing tool.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0033] See also Figures 1-4 The present invention provides a technical solution: a method for processing a groove of a workpiece with a rounded corner, characterized in that it includes the following steps:

[0034] S1. Processing a groove on the straight edge of workpiece 1 on a planer. Conventional straight edge groove processing can be processed using a planer, which is fast and accurate.

[0035] S2. Remove the workpiece 1 processed in step S1, and then use a ruler to check the straight edge bevel on the workpiece 1 to ensure that the straight edge bevel is a 20° bevel;

[0036] S3. Set up a machining platform on the rotating surface of the floor-type boring and milling machine. When setting up the machining platform, align the rotation center of the machining platform with the rotation center of the rotating surface of the machine tool to ensure that the machining platform can be driven to rotate coaxially when the rotating surface of the floor-type boring and milling machine rotates. The machining platform is composed of two base platforms 2, and the two base platforms 2 are perpendicular to each other. The two base platforms 2 are parallel to two adjacent straight edges on the workpiece 1. The base platforms 2 are set to support the workpiece 1. At the same time, the two perpendicular base platforms 2 can support the two adjacent straight edges of the rounded corners.

[0037] S4. Set up positioning templates on both sides of the processing platform. When setting up the positioning template, you need to first locate the position of the pressure plate in the template to ensure that the pressure plate can press on the straight edge of the workpiece 1. Because the straight edge of the workpiece 1 is narrow, especially after the groove processing, the space that can be pressed by the pressure plate is narrow;

[0038] S5, manufacture the arc backing 3, install the arc backing 3 on the processing platform, the arc backing 3 includes an inner circular ring 301 and an outer circular arc plate 302, the radius of the inner circular ring 301 is consistent with the radius of the fillet on the workpiece 1, the inner side surface of the outer circular arc plate 302 is in contact with the outer side surface of the inner circular ring 301, the inner circular ring 301 and the outer circular arc plate 302 are both provided with an adjustment groove 303, the inner circular ring 301 and the outer circular arc plate 302 are connected by bolts, and the inner circular ring 301 and the outer circular arc plate 302 are connected. The bolt passes through the adjusting groove 303, and the inner ring 301 is provided to support the rounded corner of the workpiece 1 to prevent the rounded corner from being deformed by force during groove processing. The outer arc plate 302 is provided to position the rounded corner of the workpiece 1 to ensure that the workpiece 1 is placed in place. The adjusting groove 303 is provided to adjust the upper and lower positions of the outer arc plate 302; when installing the arc backing 3, it is necessary to align the center of the arc backing 3 with the rotation center of the machining platform so that the arc backing 3 and the machining platform rotate coaxially when the machining platform rotates;

[0039] S6. Place the workpiece 1 on the processing platform. Before placing the workpiece 1 on the processing platform, it is necessary to pull the outer arc plate 302 upward so that the top of the outer arc plate 302 is higher than the inner ring 301. At this time, the outer arc plate 302 is used to position the fillet on the workpiece 1 to ensure that the workpiece 1 is placed in place;

[0040] S7. Use the positioning template to press the workpiece 1. When using the positioning template to press the workpiece 1, it is necessary to allow the pressure plate in the positioning template to press as much as possible on the straight edge of the workpiece 1 to ensure the fixation stability of the workpiece 1;

[0041] S8. Before processing the bevel at the rounded corner of the workpiece 1, it is necessary to pull the outer arc plate 302 downward so that the outer arc plate 302 is lower than the inner ring 301 to prevent the higher outer arc plate 302 from interfering with the processing of the machining tool;

[0042] S9, removing the workpiece 1 processed in step S8, and then using a ruler to check the fillet groove on the workpiece 1 to ensure that the fillet groove on the workpiece 1 is a 20° groove;

[0043] S10. Repeat steps S6-S9 three times to perform groove processing on the four fillets on the workpiece 1.

[0044] Working principle: When in use, select the corresponding base platform 2 and manufacture the corresponding arc paving die 3 according to the size of the workpiece 1 itself (1000MM*700MM*200MM, fillet diameter R150MM), where the radius of the inner ring 301 in the arc paving die 3 is consistent with the fillet radius of the workpiece 1, install the base platform 2 and the arc paving die 3 on the rotating surface of the floor boring and milling machine, where the positions and spacing of the two base platforms 2 match the workpiece 1, and the two base platforms 2 form a processing platform, and then select the corresponding positioning paving die, and perform straight-edge groove processing on the workpiece 1 on the planer, and inspect it after processing. After the inspection is completed, place the workpiece 1 on the processing platform, and when placing the workpiece 1, pull the outer arc plate 302 upward so that the top of the outer arc plate 302 is higher than the inner ring 301. At this time, the outer arc plate 302 It is used to place and position the fillet on the workpiece 1, ensure that the workpiece 1 is placed in place, and then use the pressure plate in the positioning mold to press and fix the straight edge of the workpiece 1, adjust the outer arc plate 302 downward so that the outer arc plate 302 is lower than the inner ring 301, and drive the processing platform to rotate through the rotating surface of the floor boring and milling machine, thereby driving the workpiece 1 to rotate. At this time, the axis of rotation of the workpiece 1 is the central axis of the fillet on the workpiece 1, ensuring that the processing tool can process around the circumference of the workpiece 1 to process the groove. With this processing method, the fillet on the workpiece 1 can be grooved without using a CNC machining center and manual grinding. Compared with processing using a CNC machining center, this processing method saves equipment costs, and compared with manual grinding, this processing method saves more than half of the construction period.
