Description

Technical Field

[0001] This utility model relates to tooling used in the bearing drilling process, specifically to a tooling that expands the processing range of drilling equipment, and belongs to the field of mechanical processing. Background Technology

[0002] Bearings are widely used in various fields. Bearing products range in diameter from 0.5 meters to 12 meters, with a wide size range and many specifications. Machining plants often need to purchase drilling equipment of different sizes to meet production needs. When a product is ordered in bulk, some equipment will be operating at full capacity while others will be shut down.

[0003] Drilling equipment has a fixed processing range when it leaves the factory, and existing tooling can only be adapted to this fixed processing range; when the product diameter exceeds the processing range, the equipment can only be stopped; thus reducing tooling utilization and reducing product production efficiency. Utility Model Content

[0004] Given the limitations of existing drilling equipment in bearing drilling, the purpose of this invention is to provide a tooling that expands the processing range of drilling equipment. This tooling can increase the processing range of drilling equipment and meet the drilling needs of bearings with similar dimensions but exceeding the equipment's travel range. It avoids the technical defect of the original design where the equipment can only be stopped when the product diameter exceeds the processing range. This improves tooling utilization, reduces tooling costs, increases equipment utilization, and improves production efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a tooling for expanding the processing range of a drilling equipment, comprising: a fixed base and a sliding cover mechanism slidably disposed on the upper end of the fixed base, the upper surface of the sliding cover mechanism bearing the workpiece to be drilled; a drilling equipment is disposed in the space above the tooling, the tooling being fixedly connected to the drilling machine by fasteners through connecting holes disposed on both sides of the fixed base; the cooperation between the sliding cover mechanism and the fixed base constitutes a telescopic sliding worktable for drilling processing;

[0006] Furthermore, the sliding cover mechanism includes: an upper cover, a sub-component unit, and bolts connecting the upper cover and the sub-component unit; the upper cover is an integral structure with a central planar design and vertically downward extending flanges at both ends, and its cross-section is a "semi-frame" structure; the upper cover spans the upper part of the fixed base, so that the central planar position falls on the upper surface of the fixed base, while the extending flanges of the upper cover extend downward from both sides of the upper part of the fixed base; a sub-component unit is provided under the extending flange at each end of the upper cover;

[0007] Furthermore, the fixed base has an I-shaped cross-section with a smaller top and a larger bottom. The upper and lower parts on both sides of the fixed base are respectively formed with an upper extension platform and a lower extension platform. A transition surface is formed between the upper extension platform and the lower extension platform. Several bolt holes are evenly arranged at equal intervals on the lower extension platform and are fixedly connected to the drilling machine by bolts. The two upper extension platforms are used to form a mating reference with the upper cover and sub-component unit.

[0008] Furthermore, the reference surfaces of the upper extension platform that mate with the upper cover and the sub-component unit are the upper surface of the extension platform, the outer side of the extension platform, and the lower bottom surface of the extension platform, respectively; the lower bottom surface of part of the middle plane of the upper cover and the inner surface of the upper cover extension flange mate with the upper surface of the extension platform and the outer side of the extension platform; the upper surface and inner side of part of the sub-component unit mate with the lower bottom surface of the upper extension platform and the upper position of the transition surface.

[0009] Furthermore, the length of the upper cover is less than the length of the fixed base;

[0010] Furthermore, the sub-component units corresponding to the extended flanges at each end of the top cover are composite structures and the sub-component units at both ends have the same structure.

[0011] Furthermore, the sub-component unit corresponding to the extended flange at each end of the top cover includes: a first short sub-component and a second long sub-component. There are two first short sub-components, which are located at both ends of the second long sub-component respectively. The two first short sub-components are respectively attached to both ends of the second long sub-component and fixed by their respective bolts, thereby realizing the assembly of the entire sub-component unit.

[0012] Furthermore, the first short sub-part and the second long sub-part have the same width and thickness; specifically, their width is 60mm and their thickness is 25mm.

[0013] Furthermore, the first short sub-component is provided with a straight threaded hole with an M20 diameter; the second long sub-component is provided with four T-shaped threaded holes evenly distributed; the two extended flanges of the top cover are provided with through holes that match the straight threaded holes on the first short sub-component and threaded blind holes that match the T-shaped threaded holes on the second long sub-component, thereby realizing the corresponding connection between the top cover and the entire sub-component unit.

[0014] In the above structure, the top cover and the sub-components at both ends of the top cover are fixed together by bolts to form a complete independent component. Through the reference cooperation between this independent component and the fixed base, the independent component can slide relative to the fixed base, thereby changing the size of the entire worktable and expanding the processing range of the drilling equipment.

[0015] The beneficial effects of the tooling of this utility model are as follows:

[0016] This tooling adopts a modular design, enabling sliding adjustment of the tooling to adjust the processing range of the drilling equipment. It can meet the drilling needs of bearings with similar dimensions but exceeding the equipment's stroke. The modular structure of this tooling improves its support strength, facilitates disassembly, and enhances processing accuracy. This solution improves tooling utilization, reduces tooling costs, increases equipment utilization, and improves production efficiency. Attached Figure Description

[0031] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0032] like Figure 1-13 The tooling shown expands the processing range of a drilling machine, comprising: a fixed base 1 and a sliding cover mechanism slidably disposed on the upper end of the fixed base 1, the upper surface of which carries the workpiece to be drilled; a drilling machine is disposed in the space above the tooling, the tooling being fixedly connected to the drilling machine by fasteners through connecting holes on both sides of the fixed base 1; the sliding cover mechanism and the fixed base 1 cooperate to form a telescopic sliding worktable for drilling processing; the size of the sliding worktable is adjusted by sliding the sliding cover mechanism relative to the fixed base 1, thereby adjusting the processing range of the drilling machine;

[0033] Based on the above scheme, when the diameter of the bearing product (the workpiece to be drilled) exceeds the processing range of the drilling equipment, the sliding cover mechanism is slid out relative to the fixed base 1 to increase the overall length of the worktable, thereby expanding the processing range of the drilling equipment.

[0034] Furthermore, the sliding cover mechanism includes: an upper cover 2, a sub-component unit, and bolts 3 connecting the upper cover 2 and the sub-component unit; the upper cover 2 is an integral structure with a central plane 2.1 and vertically downward extending flanges 2.2 at both ends, and its cross-section is a "semi-frame" structure; the upper cover 2 spans the upper part of the fixed base 1, so that the central plane 2.1 is located on the upper surface of the fixed base 1, and the extending flanges 2.2 of the upper cover 2 extend downward from both sides of the upper part of the fixed base 1; a set of sub-component units is provided under each extending flange 2.2 of the upper cover 2;

[0035] Based on the above scheme, the upper cover 2, the sub-component unit corresponding to the extended flanges 2.2 at both ends of the upper cover 2, and the fixed base 1 together form a combined structure with a reference fit, thereby realizing sliding while improving the tooling support strength and facilitating disassembly.

[0036] Furthermore, the fixed base 1 has an "I"-shaped cross-section that is smaller at the top and larger at the bottom. The upper and lower parts on both sides of the fixed base 1 are respectively formed with an upper extension platform 1.1 and a lower extension platform 1.2. A transition surface 1.3 is formed between the upper extension platform 1.1 and the lower extension platform 1.2. Several bolt holes 4 are evenly arranged at equal intervals on the lower extension platform 1.2, and it is fixedly connected to the drilling machine by bolts 3. The two upper extension platforms are used to form a mating reference with the upper cover 2 and the sub-component unit.

[0037] Furthermore, the upper extension platform 1.1 mates with the upper cover 2 and the sub-component unit on the upper surface 1.1.1, the outer side 1.1.2, and the lower surface 1.1.3 of the extension platform, respectively. Part of the lower surface of the middle plane 2.1 of the upper cover 2 and the inner surface 2.2.1 of the upper cover extension edge mate with the upper surface 1.1.1 and the outer side 1.1.2 of the extension platform. Part of the upper surface and inner side of the sub-component unit mate with the lower surface 1.1.3 and the upper part of the transition surface 1.3 of the upper extension platform. The sliding cover mechanism is connected to the fixed base 1 by the mate between the upper extension platform 1.1 of the fixed base 1, the upper cover 2, and the sub-component unit on various reference surfaces and by fastening with bolts.

[0038] Furthermore, the length of the upper cover 2 is less than the length of the fixed base 1. In this embodiment, the length of the upper cover 2 is set to 800mm, and the length of the fixed base 1 is 3000mm.

[0039] Furthermore, the sub-component unit corresponding to the extended flange 2.2 at each end of the upper cover 2 is a combined structure and the sub-component unit structures at both ends are the same;

[0040] Furthermore, the sub-component unit corresponding to the extended flange 2.2 at each end of the top cover 2 includes: a first short sub-component 5 and a second long sub-component 6. There are two first short sub-components 5, which are located at both ends of the second long sub-component 6 respectively. The two first short sub-components 5 are respectively attached to both ends of the second long sub-component 6 and fixed by their respective bolts, thereby realizing the assembly of the entire sub-component unit.

[0041] Furthermore, the first short sub-part 5 and the second long sub-part 6 have the same width and thickness. In this embodiment, their width is 60mm and their thickness is 25mm; the length of the first short sub-part 5 is 70mm and the length of the second long sub-part 6 is 640mm.

[0042] Furthermore, the first short sub-component 5 is provided with a threaded straight hole 5.1 with an M20 diameter; the second long sub-component 6 is provided with four T-shaped threaded holes 6.1 evenly distributed; the two extended flanges 2.2 of the upper cover 2 are provided with through holes 2.3 that match the threaded straight holes 5.1 on the first short sub-component 5 and threaded blind holes 2.4 that match the T-shaped threaded holes 6.1 on the second long sub-component 6, thereby realizing the corresponding connection between the upper cover 2 and the entire sub-component unit.

[0043] In the above structure, the upper cover 2 and the sub-components at both ends of the upper cover 2 are fixed together by bolts to form a complete independent component. Through the reference cooperation between this independent component and the fixed base 1, the independent component can slide relative to the fixed base 1, thereby changing the size of the entire worktable and expanding the processing range of the drilling equipment.

[0044] When this tooling is used in specific situations, such as Figure 11 , 12 As shown, the workpiece 7 is placed on the upper surface of the upper cover 2. At this time, the sliding cover mechanism is in its original, unextended state, and the position of the workpiece does not meet the processing range of the drilling equipment. Therefore, the sliding cover mechanism is slid relative to the fixed base 1, causing the upper cover 2 to extend outward relative to the fixed base 1. This changes the position of the workpiece 7 on the upper cover 2. At this time, the upper cover 2 forms a portion of outward extension area relative to the fixed base 1, as shown in the figure. Figure 13 As shown, this allows the drilling equipment to perform drilling operations on workpiece 7.

[0045] It should be noted that the length of the extension area of ​​the top cover 2 relative to the fixed base 1 is one-quarter to one-third of the total length of the top cover 2, to ensure the stability of the drilling after the top cover 2 extends out of the fixed base 1.

[0046] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0050] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
