Description

Technical Field

[0001] The present invention relates to a structural device that can prevent iron chips from a workpiece from entering a zero-point positioning system. In particular, the invention relates to a device that can, after the zero-point positioning system is positioned and coupled to a processing platform, completely prevent iron chips generated during the processing of a workpiece fixed to the zero-point positioning system from entering the interior of the zero-point positioning system. Furthermore, when the zero-point positioning system needs to be re-positioned for the next part processing, the zero-point positioning system will not produce any slight tilt, but can increase the horizontality of the workpiece coupled to the zero-point positioning system, thereby increasing the yield rate of part processing. This invention is indeed a unique and economically beneficial invention. Background Art

[0002] According to the general zero point positioning system structure (please refer to Figure 1 and Figure 2 As shown), it is composed of a movable fixed plate 2 and a positioning base 3, wherein the movable fixed plate 2 is square in shape, with a connecting block 202 on one side, and four protruding positioning shafts 201 on the bottom platform of the movable fixed plate 2.

[0003] The positioning base 3 is square in shape and has four fixed discs 302 on its upper platform surface. At the center of each fixed disc 302, there is a positioning hole 301. There are multiple balls (not shown in the figure) in the positioning hole 301, and the positioning hole 301 can be used for the positioning shaft 201 of the movable fixed disc 2 to be embedded and fixed.

[0004] When processing, the workpiece 5 that has been fixed is first assembled and fixed on the mobile fixed plate 2. At this time, the mobile fixed plate 2 is placed in another iron cabinet (not shown) next to the processing machine (not shown in the figure). Therefore, when the workpiece 5 is to be processed, the robot arm (not shown in the figure) of the processing machine (not shown in the figure) will automatically turn and automatically enter the iron cabinet (not shown) where the mobile fixed plate 2 with the workpiece 5 is placed. At this time, the robot arm (not shown in the figure) will engage with the connecting block 202 of the mobile fixed plate 2. The entire movable fixed plate 2 with the workpiece 5 fixed thereon is lifted up and moved to the top of the positioning base 3. The robot arm (not shown in the figure) will automatically descend to combine the movable fixed plate 2 and the positioning base 3 together. At this time, the positioning axis 201 of the movable fixed plate 2 will be combined with the positioning hole 301 in the fixed disc 302 on the positioning base 3 and inserted together. In this way, the zero-point positioning system 1 is combined and the workpiece 5 is fixed on the processing platform (not shown in the figure) in the processing machine (not shown). Figure 2 shown.

[0005] Please refer to Figure 2and Figure 3 As shown, at this time, when the tool 4 starts to automatically perform the processing program of the processed part 5, the iron chips 6 generated during the processing will automatically run onto the positioning base 3 of the zero point positioning system 1, that is, automatically enter the accommodating space 12 when the movable fixed plate 2 and the positioning base 3 are combined.

[0006] Please refer to Figure 4 and Figure 5 As shown, when the above-mentioned processing procedure needs to be repeated after processing, the iron filings 6 may remain on the positioning base 3, the fixed disc 302, or the positioning hole 301 on the fixed disc 302. Therefore, when the processing procedure is performed for the second or more time, the movable fixed disc 2 in the zero-point positioning system 1 structure needs to be combined with the positioning base 3 again. The iron filings 6 will be spread over the accommodating space 12, the fixed disc 302, or the positioning hole 301 on the fixed disc 302, and the movable fixed disc 2 will be slightly tilted when combined with the positioning base 3. This makes it impossible for the processed part 5 on the zero-point positioning system 1 to reach horizontal flatness, thereby causing processing errors in the processed part 5, resulting in a defective rate, and increasing processing costs and processing time. At this time, if an additional employee is required to use an air gun to blow away the iron filings 6, it is not only inconsistent with automatic processing, but also increases processing costs. Therefore, how to prevent this problem without sending additional employees to the processing site, achieve truly automated processing, increase the yield of processed parts, and reduce processing costs are the directions that the industry is eager to improve and design.

[0007] In view of this, the inventors of this case, drawing on their many years of experience in research and development in related fields, conducted in-depth research on the aforementioned deficiencies and actively sought solutions based on the aforementioned needs. After a long period of diligent research and multiple tests, they finally completed the present invention, which solves the common shortcomings and enhances its unprecedented progress and practicality. Summary of the Invention

[0008] Therefore, the main purpose of the present invention is to provide a "structural device that can block iron chips from the workpiece from entering the zero-point positioning system", mainly adding a group of frame structures between the zero-point positioning system, and through the structural features of the frame structure such as being able to embed two rubber rings and having multiple springs, and the size of the positioning frame in the frame structure is larger than the size of the positioning base in the zero-point positioning system, so that when the movable fixed disk and the positioning base of the zero-point positioning system are combined and positioned and fixed, a frame structure is combined between the two, so that the structural device that completely blocks and seals the iron chips generated by the processed parts from entering the zero-point positioning system can be achieved, and the zero-point positioning system can be increased without any slight tilt state, even if the processed parts fixed on the movable fixed disk on the zero-point positioning system reach horizontal flatness, so that the processed parts will not have processing errors, the yield rate of parts processing can be increased, and the processing cost can be reduced and truly automated processing can be achieved.

[0038] In order to provide a more detailed and clear understanding of the purpose, efficacy and structural features of the present invention, the following preferred embodiments are given and described with reference to the accompanying drawings.

[0039] First see Figure 5 and Figure 6 As shown, the present invention is a structural device that can prevent iron chips from entering the zero-point positioning system. It mainly includes a movable fixed plate 2, a frame structure 11 and a positioning base 3. The frame structure 11 is composed of a positioning frame 7, two rubber rings 8, and eight springs 10. The zero-point positioning system 1 is composed of the movable fixed plate 2 and the positioning base 3 (please refer to Figure 1 The movable fixed plate 2 is in a square shape, with a connecting block 202 on one side, and four protruding positioning shafts 201 on the bottom platform of the movable fixed plate 2.

[0040] The positioning base 3 is square in shape and has four fixed discs 302 on its upper platform surface. At the center of each fixed disc 302, there is a positioning hole 301. There are multiple balls (not shown in the figure) in the positioning hole 301, and the positioning hole 301 can be used for the positioning shaft 201 of the movable fixed disc 2 to be embedded and fixed.

[0041] The positioning frame 7 in the frame structure 11 is in a square shape, and its cross section is in a ┐ shape (such as Figure 9 As shown in the figure, two parallel square grooves (702, 703) are provided on the upper surface of the positioning frame 7, and four frame portions on the inner plane portion of the positioning frame 7 corresponding to the two parallel square grooves (702, 703) each have two circular slots 701, and the frame size of the positioning frame 7 is larger than the frame size of the positioning base 3 and is in a tight fit state, so that the positioning frame 7 can be embedded and fixed on the positioning base 3 without falling off.

[0042] The two rubber rings (8, 9) in the frame structure 11 are square in shape and have a circular cross section. The rubber rings (8, 9) can be embedded in two parallel square grooves (702, 703) of the positioning frame 7, wherein the rubber ring 8 is embedded in the square groove 703 and the rubber ring 9 is embedded in the square groove 702.

[0043] The eight springs 10 in the frame structure 11 can be embedded in the circular slots 701 of the positioning frame 7. When the positioning frame 7 and the positioning base 3 are combined, the springs 10 will not contact the surface of the positioning base 3 due to the length of the springs 10 before compression, but will be in a floating state.

[0044] When assembling (see Figure 6 、 Figure 7 and Figure 8 As shown), first complete the assembly of the frame structure 11, that is, first embed the two rubber rings (8, 9) in the square grooves (702, 703) of the positioning frame 7, and then embed the eight springs in the circular grooves 701 on the four sides of the positioning frame 7, so that the assembly of the frame structure 11 is completed (please refer to Figure 8 Then, the assembled frame structure 11 is embedded in the positioning base 3 in the zero-point positioning system structure. Since the frame size of the positioning frame 7 is larger than that of the positioning base 3 and is in a tight fit, and due to the length of the spring 10 before compression, when the positioning frame 7 and the positioning base 3 are embedded and combined, the end surface of the circular slot 701 of the positioning frame 7 will not contact the surface of the positioning base 3 due to the spring 10, but will be in a floating state (please refer to Figure 8Therefore, when the movable fixed plate 2 and the positioning base 3 in the zero-point positioning system are embedded and fixed together, in addition to forming a frame structure 11 between the movable fixed plate and the positioning base in the zero-point positioning system structure, the eight springs also provide a buffer and allow the movable fixed plate 2 to smoothly move downward during the embedded and fixed downward movement by the robot arm (not shown) without causing damage to the movable fixed plate 2 or the positioning base 3. In addition, the frame structure 11 can completely seal the accommodating space 12 between the movable fixed plate 2 and the positioning base 3, preventing any foreign matter from entering. This completes the assembly of the present invention.

[0045] When processing (please refer to Figure 6 、 Figure 8 and Figure 9 As shown in the figure, the workpiece 5 that has been fixed is first assembled and fixed on the mobile fixed plate 2. At this time, the mobile fixed plate 2 is placed in another iron cabinet (not shown in the figure) next to the processing machine (not shown in the figure). Therefore, when the workpiece 5 is to be processed, the robot arm (not shown in the figure) of the processing machine (not shown in the figure) will automatically turn and automatically enter the iron cabinet (not shown in the figure) where the mobile fixed plate 2 with the workpiece 5 is placed. At this time, the robot arm (not shown in the figure) will be combined with the connecting block 202 of the mobile fixed plate 2 to pick up the entire iron cabinet where the workpiece 5 is fixed. The movable fixed plate 2 of the component 5 is moved to the upper part of the positioning base 3, and the mechanical arm (not shown) is automatically lowered to cause the movable fixed plate 2 and the positioning base 3 to be combined together. At this time, since a frame structure 11 is embedded in the positioning base 3, when the positioning shaft 201 of the movable fixed plate 2 and the positioning hole 301 in the fixed disc 302 on the positioning base 3 are combined and inserted together, the positioning combination of the zero point positioning system 1 is completed, and the frame structure 11 of the present invention is fixed between the movable fixed plate 2 and the positioning base 3 (please refer to the embodiment of the present invention). Figure 7 As shown), the processed part 5 is also fixed on the processing platform (not shown) in the processing machine (not shown).

[0046] At this time, when the tool 4 starts to automatically perform the processing procedure of the workpiece 5, the iron chips 6 generated during the processing will be completely blocked and sealed by the frame structure 11 to prevent the iron chips 6 from automatically running into the accommodating space 12 in the positioning base 3 of the zero point positioning system 1, or onto the fixed disk 302, or into the positioning hole 301 on the fixed disk 302.

[0047] Therefore, when the above-mentioned processing procedure is repeated after the processing is completed, no piece of iron filings 6 will remain on the positioning base 3, or the fixed disk 302, or the positioning hole 301 on the fixed disk 302 due to the frame structure 11 of the present invention. Therefore, when the processing procedure is repeated for the second time or more, when the movable fixed disk 2 in the zero-point positioning system 1 structure is combined with the positioning base 3 again, the iron filings 6 will not be completely distributed in the accommodating space 12, or on the fixed disk 302, or on the positioning hole 301 on the fixed disk 302. 01, it is completely blocked by the frame structure 11 of the present invention, so that when the movable fixed plate 2 and the positioning base 3 are combined, the movable fixed plate 2 will not be slightly tilted at all, so that the processed parts 5 on the zero-point positioning system 1 will not be slightly tilted, and the horizontal flatness can be fully achieved, thereby preventing the processed parts 5 from being processed incorrectly and generating a defective rate. In addition to reducing processing costs and processing time, there is no need to add an employee to use an air gun to spray away the iron chips 6 as is usually required, and it is fully in line with automatic processing.

[0048] In summary, the structural device of the present invention, which can prevent iron chips from the workpiece from entering the zero-point positioning system, is the result of the careful design of the inventors of this case. It is not only practical and convenient, but also quick and easy to assemble and use, and has automatic blocking and sealing to prevent foreign matter, and is fully automated, and has the characteristics of increasing yield and reducing processing costs.

[0049] However, the above description only describes the preferred embodiments of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent structural changes made by applying the description and claims of the present invention are also included in the scope of the present invention and are hereby stated.
