Technical Field

[0001] This application relates to the field of tooling fixtures, and more specifically, to a tooling fixture. Background Technology

[0002] Tooling fixtures are specialized tools used for positioning, clamping, and supporting cylindrical parts during manufacturing, machining, or assembly. Taking tooling fixtures for machining cylindrical parts as an example, such fixtures are commonly found in pressure vessels, pipelines, boilers, ships, and machinery. Therefore, the design of these tooling fixtures needs to be customized according to the dimensions of the cylindrical parts.

[0003] In related technologies, to improve the versatility of tooling fixtures, tooling fixtures generally include a support structure and a limiting structure.

The limiting structure has a limiting surface, and the limiting surface and the two support surfaces together form a limiting space for the limiting cylinder.

[0004] However, the aforementioned tooling fixture has a limited range of cylinder sizes to which it can be adapted because the distance between the two limiting surfaces is not adjustable, which affects the versatility of the tooling fixture. Utility Model Content

The first adjustment hole is disposed at the first end of the limiting portion and extends toward the second end, and the second adjustment hole is disposed at the second end of the limiting portion and extends toward the first end.

[0014] The connecting part includes a first connecting part and a second connecting part. One end of the first connecting part is connected to the first support body, and the other end is connected to the limiting part through a first adjustment hole. One end of the second connecting part is connected to the second support body, and the other end is connected to the limiting part through a second adjustment hole.

[0015] According to one embodiment of this application, the first adjustment hole is a first elongated strip hole extending along a first direction;

[0016] And / or, the second adjustment hole position is a second elongated strip hole extending along the first direction.

[0018] And / or, the second adjustment hole includes a plurality of second sub-adjustment holes, which are spaced apart along a first direction.

[0019] According to one embodiment of this application, the first connecting part includes a first threaded sleeve and a first threaded rod. The first threaded sleeve is connected to the first support body, and the first threaded rod is disposed on the first threaded sleeve and passes through the first adjusting hole. The position adjusting structure further includes a first fastener, which is used to fix the limiting part to the first threaded rod.

[0020] According to one embodiment of this application, the tooling fixture further includes a first sliding structure extending along a first direction, wherein the first support and the second support are adjustablely positioned via the first sliding structure.

[0021] According to one embodiment of this application, the first sliding structure includes a slide rail and a slider, the slide rail extends along a first direction, the slider is slidably connected to the slide rail, and the slider is fixedly connected to the first support body;

[0046] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this application will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0047] The features, structures, or characteristics described below can be combined in any suitable manner in one or more embodiments. Numerous specific details are provided in the following description to give a full understanding of embodiments of this application. However, those skilled in the art will recognize that the technical solutions of this application can be practiced without one or more of the specific details described, or other methods, components, materials, etc., can be employed. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring various aspects of this application.

[0048] Currently, with the increasing precision and complexity of mechanical products, the frequency and variety of parts replacement are also increasing. Traditional machining methods, typically employing a "one part, one fixture" approach or using combination fixtures, are no longer sufficient to meet the demands of modern CNC machining for high efficiency, high precision, and high adaptability. The traditional "one part, one fixture" method is not only costly to manufacture, but also consumes significant machine tool time during fixture changes, involving tedious adjustments and high labor intensity. Combination fixtures, on the other hand, suffer from poor positioning accuracy, requiring workpiece alignment and repeated coordinate system settings each time a part is clamped, severely impacting machining efficiency and increasing the probability of errors. Furthermore, unused fixtures occupy a large amount of space, and the accumulation of old and scrapped fixtures not only affects the cleanliness of the work environment but may also pose safety hazards.

[0049] Therefore, the purpose of this invention is to provide a tooling fixture suitable for CNC machining of cylindrical parts. This fixture can adapt to the clamping requirements of cylindrical parts of different diameters and lengths, achieving "one clamp for multiple uses" and meeting the clamping requirements of most cylindrical parts. Through the application of this invention, rapid adjustment, simple operation, high positioning accuracy, unified reference, and short machine-time adjustment can be achieved. It has good versatility and practicality, significantly improving machining efficiency and the convenience of fixture management.

[0050] The specific embodiments of the tooling fixture are described below with reference to the accompanying drawings. For ease of explanation, the arrangement direction of the first support surface and the second support surface is defined as the first direction; the limiting direction of the limiting structure is defined as the second direction; and the third direction is defined as a direction that is perpendicular to both the first direction and the second direction.

[0051] like Figure 1 As shown, the tooling fixture 10 in this embodiment includes a support structure 100 and a limiting structure 200.

[0052] The support structure 100 includes a first support surface 116 and a second support surface 121, the positions of which are adjustable along a first direction D1. The first support surface 116 and the second support surface 121 are used to support the cylindrical structure, providing a stable support foundation for the cylindrical body.

[0053] The limiting structure 200 includes a connecting portion and a limiting portion 230. The limiting portion 230 extends along a first direction D1. The connecting portion connects the support structure 100 and the limiting portion 230. The limiting portion 230 is adjustablely positioned on the connecting portion along a second direction D2. The first support surface 116, the second support surface 121, and the limiting portion 230 form a limiting space. A position adjustment structure 240 is also provided between the connecting portion and the limiting portion 230. The position adjustment structure 240 is used to adjust the connection point between the connecting portion and the limiting portion 230 along the first direction D1.

[0054] In this embodiment, the positions of the first support surface 116 and the second support surface 121 along the first direction D1 are adjustable. When clamping a small-sized cylinder, the first support surface 116 and the second support surface 121 can be brought closer to each other along the first direction. When the size of the clamped cylinder increases, the first support surface 116 and the second support surface 121 can be moved further apart along the first direction D1 until a stable support is formed for the cylinder. The limiting structure 200 includes a connecting part and a limiting part 230. The connecting part is used to connect the support structure 100 and the limiting part 230, and the limiting part 230 is used to limit the cylinder mechanism in the second direction D2. After the cylinder is placed between the first support surface 116 and the second support surface 121, the limiting part 230 can be adjusted along the second direction D2 so that the limiting part 230 is clamped on the top of the cylinder. In this way, the limiting space is formed by the first support surface 116, the second support surface 121 and the clamping part, and the cylinder is stably clamped in the limiting space, which effectively reduces the risk of the cylinder shaking during subsequent processing.

[0055] In addition, a position adjustment structure 240 is provided between the limiting part 230 and the connecting part. The position adjustment structure 240 allows the installation position of the limiting part 230 to be adjusted accordingly as the support structure 100 changes. When the first support surface 116 and the second support surface 121 are adjusted in the same direction to accommodate cylinders of different diameters, the limiting part 230 can also adjust its position synchronously through the position adjustment structure 240 to maintain the optimal limiting contact relationship with the cylinder.

[0056] Therefore, the tooling fixture 10 of this embodiment can adapt to more cylindrical structures of different sizes, shapes and center heights, thereby improving the versatility of the tooling fixture 10.

[0057] Of course, in other embodiments, one of the first support surface 116 and the second support surface 121 can be fixedly set, while the other of the first support surface 116 and the second support surface 121 can be set in an adjustable position. This setting method can also realize the position between the first support surface 116 and the second support surface 121 is adjustable, so that the first support surface 116 and the second support surface 121 can support cylinders of more sizes.

[0058] Furthermore, such as Figure 1 and Figure 2 As shown, the first support surface 116 and the second support surface 121 can be inclined surfaces. For example, the first support surface 116 gradually inclines toward the second support surface 121 in a direction from near the limiting portion 230 to away from the limiting portion 230. Correspondingly, the second support surface 121 then gradually inclines toward the first support surface 116 in a direction from near the limiting portion 230 to away from the limiting portion 230.

[0059] like Figure 1As shown, in some embodiments, the support structure 100 includes a first support body 110 and a second support body 120. A first support surface 116 is disposed on the first support body 110, and a second support surface 121 is disposed on the second support body 120. Both the first support body 110 and the second support body 120 are adjustable along the first direction D1, thereby improving the adjustment flexibility of the tooling fixture 10.

[0060] Of course, in other embodiments, only one of the first support 110 and the second support 120 may be configured to be adjustable along the first direction D1. This configuration is beneficial to reducing the processing cost of the tooling fixture 10.

[0061] The specific structures of the first and second supports are described below with reference to the accompanying drawings.

[0062] like Figure 2 As shown, the first support body 110 includes a first support base plate 111, a first support column 112, a first support rib 113, and a second support rib 114. The first support base plate 111 supports the first support column, the first support rib 113, and the second support rib 114. A first positioning hole 115 is provided on the first support base plate 111, which is used to position the first support body 110 when its position is adjusted. The first support rib 113 and the second support rib 114 are respectively disposed on both sides of the first support column 112 along a first direction D1. The first support rib 113 connects one side wall of the first support column 112 to the top wall of the first support base plate 111, and the second support rib 114 connects the other side wall of the first support column 112 to the top wall of the first support base plate 111.

[0063] It should be emphasized that the cross-sectional area of ​​the first support column 112 is larger than that of the first support rib 113 and the second support rib 114. The first support rib 113 is located on the side of the first support column 112 closer to the second support body 120. The top surface of the first support rib 113 and the top surface of the first support column 112 together form the first support surface 116, thereby ensuring the support area of ​​the first support surface 116. The second support rib 114 is located on the side of the first support column 112 away from the second support body 120. The second support rib 114 is used to connect with the first connecting part 210 of the limiting structure 200, so that the first connecting part 210 can move synchronously with the first support body 110, thereby realizing the synchronous adjustment of the first support body 110 and the first connecting part 210.

[0064] The structure of the second support 120 is similar to that of the first support 110, the only difference being that the inclination direction of the second support surface 121 of the second support 120 is opposite to that of the first support surface 116. The structure of the second support 120 will not be described in detail here.

[0065] The specific embodiments of the position adjustment structure are described below with reference to the accompanying drawings.

[0066] Specifically, in some embodiments, such as Figure 1 and Figure 3 As shown, the limiting part 230 includes a first end and a second end disposed opposite to each other along the first direction D1. The position adjustment structure 240 includes a first adjustment hole 241 and a second adjustment hole 242. The first adjustment hole 241 is disposed at the first end of the limiting part 230 and extends toward the second end, and the second adjustment hole 242 is disposed at the second end of the limiting part 230 and extends toward the first end. The connecting part includes a first connecting part 210 and a second connecting part 220. One end of the first connecting part 210 is connected to the first support body 110, and the other end is connected to the limiting part 230 through the first adjustment hole 241. One end of the second connecting part 220 is connected to the second support body 120, and the other end is connected to the limiting part 230 through the second adjustment hole 242.

[0067] like Figure 1 and Figure 3 As shown, when adjusting the positions of the first support 110 and the second support 120 to clamp a larger cylinder, the limiting part 230 can be first removed from the first connecting part 210 and the second connecting part 220. Then, the first support 110 and the second support 120 are moved away from each other. At this time, the first support 110 and the second support 120 will move synchronously with the first connecting part 210 and the second connecting part 220 until the distance between the first support 110 and the second support 120 meets the support requirements for the cylinder. The cylinder is then placed between the first support surface 116 and the second support surface 121. The end of the first support 110 is then inserted into the first adjustment hole 241 on the limiting part 230, and the second support 120 is inserted into the second adjustment hole 242. The limiting part 230 is then locked with the first fastener, so that the limiting part 230 clamps the cylinder, thereby stably clamping the cylinder on the tooling fixture 10.

[0068] like Figure 3 As shown, in the first embodiment, the first adjustment hole 241 includes a plurality of first sub-adjustment holes 2411, which are spaced apart along the first direction D1. The second adjustment hole 242 includes a plurality of second sub-adjustment holes 2421, which are spaced apart along the first direction D1. This arrangement creates multiple selectable adjustment positions, allowing the first connecting part 210 or the second connecting part 220 to be inserted into different holes to adjust the positions of the first support 110 and the second support 120.

[0069] It is understandable that the adjustment precision of the first support 110 and the second support 120 depends on the spacing between each sub-adjustment hole; the smaller the spacing, the finer the adjustment. The adjustment range of the first support 110 and the second support 120 is determined by the number and distribution range of the sub-adjustment holes; the more numerous and wider the distribution, the larger the adjustment range.

[0070] It should be noted that, as Figure 3 As shown, multiple first sub-adjustment holes 2411 are spaced apart along the first direction D1 at the first end of the limiting part 230, and multiple second sub-adjustment holes 2421 are similarly spaced apart along the first direction D1 at the second end of the limiting part 230. The middle region of the limiting part 230 does not have either the first sub-adjustment holes 2411 or the second sub-adjustment holes 2421. This arrangement helps to ensure the structural strength of the limiting part 230 and effectively reduces the probability of deformation of the limiting part 230.

[0071] In this embodiment, the limiting part 230 is a limiting plate. In other embodiments, the limiting part may also be a limiting rib or other structure.

[0072] In addition, this embodiment shows the limiting part 230 in a straight state. In some embodiments, the limiting part 230 may also be an arc-shaped structure to increase the contact area between the limiting part 230 and the cylinder, thereby achieving a better limiting effect.

[0073] In the second embodiment (not shown in the figure), the first adjustment hole is a first elongated strip hole extending along the first direction D1. The first elongated strip hole is a continuously extending structure, and during adjustment, the first connecting part can slide within the first elongated strip hole, thereby realizing continuous position adjustment of the first connecting part.

[0074] Correspondingly, the second adjustment hole extends along the first direction D1, and the second connecting part can be continuously adjusted within the second elongated hole.

[0075] In a third embodiment (not shown in the figure), the first adjusting hole may be configured as an adjusting elongated hole, and the second adjusting hole may be configured as including a plurality of second sub-adjusting holes.

[0076] Furthermore, such as Figure 3 As shown, in some embodiments, the first connecting part 210 includes a first threaded sleeve 211 and a first threaded rod 212. The first threaded sleeve 211 is connected to the first support body 110. The first threaded rod 212 is disposed on the first threaded sleeve 211 and passes through the first adjusting hole 241. The position adjusting structure 240 also includes a first fastener, which is used to fix the limiting part 230 to the first threaded rod 212.

[0077] The first threaded sleeve 211 can be fixedly connected to the first support body 110. The first threaded rod 212 and the first threaded sleeve 211 are connected by threads. This threaded connection makes the two tightly connected, and the first threaded rod 212 is difficult to move in the second direction D2, thereby ensuring the clamping effect of the limiting part 230 on the cylinder.

[0078] Alternatively, the first fastener can be a nut, and the limiting part 230 can be connected to the first threaded rod 212 via the first fastener. For example, the first threaded rod 212 can be an M24 threaded rod (a metric coarse-pitch threaded rod with a diameter of 24 mm). The threaded hole in the first threaded sleeve 211 is set according to the specifications of the first threaded rod 212. Accordingly, the diameter of the first sub-adjusting hole 2411 can be 24 mm.

[0079] like Figure 3 As shown, the structure of the second connecting part 220 is the same as that of the first connecting part 210, and will not be described again in this embodiment.

[0080] like Figure 1 and Figure 4 As shown, the tooling fixture 10 also includes a first sliding structure 300 extending along the first direction D1, and the first support 110 and the second support 120 are adjustablely positioned via the first sliding structure 300.

[0081] Specifically, such as Figure 4 As shown, the first sliding structure 300 includes a slide rail 310 and a slider 320. The slide rail 310 extends along a first direction D1, and the slider 320 is slidably connected to the slide rail 310 and fixedly connected to the first support body 110. The slide rail 310 also has a third adjustment hole 330 extending along the first direction D1, and the first support body 110 has a first positioning hole 115. The tooling fixture 10 also includes a second fastener passing through the first positioning hole 115 and the third adjustment hole 330. Correspondingly, the second support body 120 has a second positioning hole 122, and the tooling fixture 10 also includes a third fastener passing through the second positioning hole 122 and the third adjustment hole 330.

[0082] It should be noted that the third adjustment hole 330 includes a plurality of third sub-adjustment holes 331 arranged at intervals in the first direction D1. The distance between two adjacent third sub-adjustment holes 331 is equal to the distance between two adjacent first sub-adjustment holes 2411 and the distance between two adjacent second sub-adjustment holes 2421, so as to realize the synchronous adjustment of the support structure 100 and the limiting structure 200.

[0083] For example, the second and third fasteners can be screws, and the diameter of the third sub-adjustment hole 331 is the same as the diameter of the first sub-adjustment hole 2411.

[0084] like Figure 1 and Figure 5 As shown, in some embodiments, the tooling fixture 10 further includes a base 500 and a second sliding structure 400. The second sliding structure 400 is disposed between the base 500 and the first sliding structure 300, and extends along a third direction. Specifically, the second sliding structure 400 includes a groove 410 and a sliding protrusion 420. The groove 410 is disposed on the base 500, and the sliding protrusion 420 is disposed on the bottom of the first sliding structure 300. The second sliding structure 400 enables the first sliding structure 300 to move along a third direction. The movement of the first sliding structure 300 along a third direction can drive the first support 110, the second support 120, and the limiting structure to move upward along a third direction, thereby enabling the clamping position of the tooling fixture 10 to move in the axial direction of the cylinder, improving the clamping flexibility of the tooling fixture 10.

[0085] Of course, in other embodiments, the groove 410 may also be provided on the first sliding structure 300, and the sliding protrusion 420 may be provided on the base 500 along a third direction.

[0086] It should also be noted that, such as Figure 6 As shown, the base 500 is also provided with a fourth adjustment hole 510. The fourth adjustment hole 510 includes a plurality of fourth sub-adjustment holes 511 spaced apart along a third direction. The tooling fixture 10 also includes a fourth fastener. The fourth fastener can be inserted into the third sub-adjustment hole 331 and the fourth sub-adjustment hole 511 of the first sliding structure 300 to fix the first sliding structure 300 to the base 500.

[0087] Furthermore, such as Figure 1 and Figure 3 As shown, in some embodiments, the support structure 100, the limiting structure 200, and the first sliding structure 300 form a clamping assembly, and the tooling fixture 10 includes multiple clamping assemblies spaced apart along a third direction. The multiple clamping assemblies enable multi-point clamping of the cylinder, thereby improving the stability of the cylinder clamping. Furthermore, when the cylinder has a variable diameter structure, the multiple clamping assemblies can be adjusted to achieve tight clamping of different diameter sections of the cylinder, further enhancing the versatility of the tooling fixture 10.

[0088] For example, such as Figure 5 As shown, the tooling fixture 10 may include a first clamping assembly 11, a second clamping assembly 12, a third clamping assembly 13, and a fourth clamping assembly 14. When the diameter of the cylinder gradually increases in the direction from the first clamping assembly 11 to the fourth clamping assembly 14, the limiting space of each clamping assembly can be adjusted respectively, thereby achieving tight clamping of the cylinder.
