Description

Technical Field

[0001] This utility model belongs to the field of ring component processing tooling technology, specifically a ring component processing tooling. Background Technology

[0002] High-speed bearings come in many series, and bearing covers and thrust covers are all ring-shaped components. However, the dimensions (inner diameter, outer diameter, thickness, etc.) of ring-shaped components in different series are often different. This results in a large number of tooling fixtures required when precision machining these ring-shaped components. Each specification needs to be designed, which takes up a lot of warehouse space and leads to frequent tooling changes. Tooling changeover is slow, the time spent off the machine is long, it is easy to become stagnant, it is inconvenient for workers to use, and the production efficiency is low. Utility Model Content

[0003] In view of the above-mentioned problems existing in the prior art, the purpose of this utility model is to provide a tooling for processing ring-shaped parts. The same tooling is applicable to the fixing of multiple different ring-shaped parts. It is simple and convenient to use, facilitates the subsequent processing of ring-shaped parts, greatly reduces the number of toolings, reduces the space occupied by tooling in the warehouse, saves costs, reduces changeover time, reduces labor intensity, and improves production efficiency. It is especially suitable for small-batch production of ring-shaped parts such as bearing covers and thrust covers.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A machining fixture for annular components includes a machine base, I-shaped sliders, and slider fixing components. The machine base serves as the base of the fixture and has multiple radial grooves arranged radially around the central axis of the machine base. Multiple I-shaped sliders slide on the multiple grooves and can be fixed to the machine base by the slider fixing components. The annular workpiece to be machined can be supported and fixed on the multiple I-shaped sliders.

[0006] As a further improvement to the above technical solution:

[0007] The slide is a groove formed by the indentation of the upper end face of the machine base. The cross-section of the slide is an inverted T-shape, and the opening at one end of the slide is located on the circumferential side of the machine base.

[0008] The I-shaped slider is provided with at least one slider fixing hole. The slider fixing component passes through the slider fixing hole and is pressed against the machine base to fix the I-shaped slider.

[0009] The slider fixing hole connects to the bottom surface of the slide groove. The slider fixing component is a moving steel ball, and the length of the slider fixing component is shorter than the length of the slider fixing hole.

[0010] The tooling also includes a workpiece fixing component. The I-shaped slider has at least one workpiece fixing hole. The workpiece fixing component passes through the workpiece and is inserted into the workpiece fixing hole to fix the workpiece on the I-shaped slider.

[0011] When each I-shaped slider has at least two workpiece fixing holes, the length and / or diameter of each workpiece fixing hole is different.

[0012] The tooling also includes limiting bolts for limiting the I-shaped slider. The number of limiting bolts is the same as the number of slides. The limiting bolts are inserted into the machine base from the circumferential side of the machine base. The bolt shank of the limiting bolt is inserted into the machine base, but the bolt head is not inserted into the machine base. The bolt head of the limiting bolt is provided with a notch. Each limiting bolt corresponds to each slide. When the limiting bolt is rotated, the limiting bolt can be rotated until the bolt head blocks the I-shaped slider on the corresponding slide from slipping off or does not block the I-shaped slider on the corresponding slide from slipping off.

[0013] The tooling also includes a splicing surface support block that assists in supporting the workpiece.

[0014] The beneficial effects of this utility model are: the same tooling is applicable to the fixing of a variety of different ring parts, it is simple and convenient to use, facilitates the subsequent processing of ring parts, greatly reduces the number of tooling, reduces the space occupied by tooling in the warehouse, saves costs, reduces changeover time, reduces labor intensity, and improves production efficiency. It is especially suitable for small-batch production of ring parts such as bearing covers and thrust covers. Attached Figure Description

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0021] A tooling for machining ring-shaped components, such as Figures 1-4 As shown, it includes a base 1, an I-shaped slider 2, a workpiece fixing part 3, a limit bolt 4, a slider fixing part 5, and a splicing surface support block 6.

[0022] The base 1 serves as the base for the tooling. The base 1 has a cylindrical outline; in other words, the base 1 is obtained by slotting a groove in the cylinder. Preferably, the base 1 is relatively thin, meaning that the diameter of the base 1 is greater than its height.

[0023] The base 1 is provided with multiple sliding grooves 7, each groove being a recess formed inward from the upper end face of the base 1, and the grooves 7 are radially recessed. The multiple sliding grooves 7 are arranged radially and evenly around the central axis of the base 1, meaning the length direction of the sliding groove 7 is radial to the base 1, and the cross-section of the sliding groove 7 is an inverted T-shape. Preferably, there is also a recessed central groove in the middle of the upper end face of the base 1. The sliding groove 7 penetrates the circumferential side of the base 1, meaning one inlet and outlet of the sliding groove 7 are located on the circumferential side of the base 1 to facilitate the installation and removal of the I-shaped slider 2.

[0024] Multiple I-shaped sliders 2 are provided, and the multiple I-shaped sliders 2 are respectively slidably mounted on multiple sliding grooves 7, that is, the multiple I-shaped sliders 2 are arranged in a ring array.

[0025] The I-shaped slider 2 is provided with two slider fixing holes 8 and at least one workpiece fixing hole 9.

[0026] The slider fixing component 5 fixes the I-shaped slider 2 to the machine base 1 through the slider fixing hole 8. Specifically, the slider fixing hole 8 is a through hole penetrating the height direction of the I-shaped slider 2, and the height direction of the I-shaped slider 2 is parallel to the central axis of the machine base 1. Two slider fixing holes 8 are arranged in parallel and spaced apart. In this embodiment, the slider fixing component 5 is a moving steel ball, and the slider fixing hole 8 connects to the bottom surface of the slide groove 7. The slider fixing hole 8 is provided with an internal thread. When the moving steel ball is screwed into the slider fixing hole 8, the end of the moving steel ball contacts and presses against the bottom surface of the slide groove 7, thus fixing the I-shaped slider 2 to the machine base 1. The moving steel ball is also known as the moving steel ball positioning screw. Its end is provided with a rotatable steel ball. Therefore, when the moving steel ball is not pressed against the bottom surface of the slide groove 7, the I-shaped slider 2 can slide on the slide groove 7. The steel ball at the end of the moving steel ball rolls adaptively and does not affect the movement of the I-shaped slider 2. Preferably, the length of the moving steel ball is less than the height of the slider fixing hole 8, so that the moving steel ball falls entirely into the slider fixing hole 8 without exceeding the slider fixing hole 8. This does not interfere with other operations and components. When screwing in the moving steel ball, tools such as screwdrivers can be used.

[0027] The workpiece fixing hole 9 is used to fix the workpiece 10 (bearing cover, thrust cover, etc.) to be processed on the machine base 1. Specifically, the workpiece fixing hole 9 is a blind hole, and the length direction of the workpiece fixing hole 9 is parallel to the length direction of the slider fixing hole 8. When there are two or more workpiece fixing holes 9 on a I-shaped slider 2, the workpiece fixing holes 9 are arranged in parallel intervals, and the arrangement direction of each workpiece fixing hole 9 is parallel to the length direction of the corresponding groove 7 of the I-shaped slider 2. The workpiece fixing member 3 is passed through the workpiece 10 and inserted into the workpiece fixing hole 9 to fix the workpiece 10 on the I-shaped slider 2. In this embodiment, the workpiece fixing member 3 is a countersunk screw. The multiple workpiece fixing holes 9 on each I-shaped slider 2 are located on multiple concentrically arranged circumferences, and all workpiece fixing holes 9 on all I-shaped sliders 2 can be located on multiple concentrically arranged circumferences at the same time.

[0028] Preferably, the dimensions of each workpiece fixing hole 9 can be designed such that the length and / or diameter of the workpiece fixing hole 9 gradually increases in the direction away from the central axis to accommodate countersunk screws of different sizes and workpieces 10 of different diameters.

[0029] Preferably, the upper surface of the I-shaped slider 2 is a plane parallel to the bottom surface of the machine base 1, and the upper surfaces of all I-shaped sliders 2 are located in the same plane, so as to ensure the levelness of the workpiece 10 supported and fixed on the upper surface of the I-shaped slider 2.

[0030] In this embodiment, the workpiece fixing hole 9 on each I-shaped slider 2 is located between two slider fixing holes 8.

[0031] In this embodiment, three workpiece fixing holes 9 are provided.

[0032] The number of limiting bolts 4 is the same as the number of slide grooves 7. The limiting bolts 4 are inserted into the machine base 1 from the circumferential side of the machine base 1, with the screw of the limiting bolt 4 inserted into the machine base 1 but the bolt head not inserted. Each limiting bolt 4 corresponds to a slide groove 7, with the screw of each limiting bolt 4 located below its corresponding slide groove 7, and the bolt head of the limiting bolt 4 extending beyond and above the bottom surface of the slide groove 7. This achieves the limiting of the I-shaped slider 2, preventing it from sliding out of the slide groove 7. The bolt head of the limiting bolt 4 has a notch. When the limiting bolt 4 is rotated, it can be rotated until the notch of the bolt head of the limiting bolt 4 faces upward. At this time, the bolt head of the limiting bolt 4 does not extend beyond the bottom surface of the slide groove 7, and the I-shaped slider 2 can be removed from the slide groove 7, facilitating the disassembly of the I-shaped slider 2.

[0033] At least two splicing surface support blocks 6 are provided. These blocks supplement and assist in supporting workpieces 10 with larger diameters and in supporting the splicing surfaces of the workpieces 10. The splicing surface support blocks 6 are located between two adjacent I-shaped sliders 2 on the machine base 1. They can be fixedly connected to the machine base 1 and the workpiece 10 using screws, bolts, or other fasteners. The splicing surface support blocks 6 can also be used flexibly as independent or movable components, and their use can be selected or omitted depending on specific needs.

[0034] Based on the above structure, the working principle and process of this utility model are as follows: The annular workpiece 10 (bearing cover, thrust cover, etc.) consists of two symmetrical fan rings. The two fan rings are placed on the tooling and supported on the upper end face of the I-shaped slider 2. The corresponding workpiece fixing hole 9 is selected according to the diameter of the workpiece 10. The countersunk screw is passed through the workpiece 10 and inserted into the selected workpiece fixing hole 9. During this process, the I-shaped slider 2 is moved adaptively. After the workpiece 10 is fixedly connected to all the I-shaped sliders 2, the workpiece 10 and the machine base 1 share a common central axis. Then, the moving steel ball is tightened with a screwdriver or other tools, so that the end of the moving steel ball is pressed against the slide groove 7, fixing the I-shaped slider 2 on the machine base 1 so that it cannot move. At this time, the workpiece 10 is fixed on the tooling, and the plane where the workpiece 10 is located is parallel to the bottom surface of the machine base 1, so that the inner circle, outer circle, end face, and other parts of the workpiece 10 can be precision machined. As for the moving steel balls, one or two can be tightened as needed and in specific circumstances. For example, if the slider fixing hole 8 near the central axis is blocked by the supported workpiece 10, only the moving steel balls away from the central axis can be tightened. As can be seen from the above, the annular diameter formed by all I-shaped sliders 2 can be reduced or increased to accommodate workpieces 10 with different diameters. When the diameter of the workpiece 10 is large, resulting in a large gap between adjacent I-shaped sliders 2, the splicing surface support block 6 can be selected to support the splicing point of the two fan rings of the workpiece 10.

[0035] Finally, it is necessary to state that the above embodiments are only used to further illustrate the technical solution of this utility model in detail, and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made by those skilled in the art based on the above content of this utility model shall fall within the scope of protection of this utility model.
