Description

Technical Field

[0001] This utility model relates to the field of disc-type workpiece processing technology, and more specifically, to a multi-purpose clamping fixture. Background Technology

[0002] In the manufacturing of aero-engines and other similar fields, bladed disks are among the most important components, and their size, shape, and precision requirements vary depending on the engine model.

[0003] In related technologies, tooling for impeller-type workpieces mainly adopts a traditional integral tooling structure. This type of tooling is usually made of a single material through integral casting or machining. Its design concept focuses on meeting the basic positioning and support functions of the impeller to ensure the accuracy of the relative position of the impeller during processing or assembly. However, the fixed structure of integral tooling cannot be quickly adjusted to fit the diverse specifications of impellers and the processing requirements of different models of impellers. Utility Model Content

[0004] The problem this utility model aims to solve is that the fixed structure of the integral tooling in the related technology cannot meet the processing requirements of diverse specifications and different models of impellers.

[0005] To address the aforementioned problems, this utility model provides a multi-purpose clamping fixture for clamping impeller-shaped workpieces. The multi-purpose clamping fixture includes a support module, a positioning module, and a clamping module. The support module includes a first support plate for supporting the impeller-shaped workpiece. The first support plate has multiple circumferentially spaced grooves, each groove arranged radially along the first support plate. The positioning module is located in one of the grooves and configured to slide along the groove, partially exposing the first support plate and used to position the impeller-shaped workpiece. The clamping module includes a first clamping module and / or a second clamping module. The first clamping module is located in the groove and configured to slide along the groove, used to radially clamp the impeller-shaped workpiece. The second clamping module is located at the center of the first support plate and configured to move along the thickness direction of the impeller-shaped workpiece, used to vertically clamp the impeller-shaped workpiece.

[0006] Optionally, the first clamping module includes two clamping units arranged radially opposite to each other along the first support plate. Each clamping unit includes a second flange stud, a baffle, a clamping member, and a sliding column. The sliding column is slidably connected to the slide groove, and the clamping member is slidably sleeved on the sliding column. The second flange stud is disposed in the slide groove and threadedly connected to the clamping member. The baffle is sleeved on the second flange stud and elastically connected to the clamping member. The baffle is used to abut against the surface of the first support plate. In the two clamping units, the clamping member of one clamping unit is used to clamp the impeller-like workpiece radially inward, and / or the clamping member of the other clamping unit is used to clamp the impeller-like workpiece radially outward.

[0007] Optionally, the clamping member includes a mounting part and a clamping part that are fixedly connected. The mounting part is threadedly connected to the second flange stud and slidably connected to the sliding stud. The clamping part is used to press the bladed disk-like workpiece against the surface of the first support disk. The clamping parts of the two clamping units are arranged opposite to each other.

[0008] Optionally, the second flange stud extends vertically through the slide groove, with one end of the second flange stud protruding from the bottom surface of the first support plate and the other end protruding from the surface of the first support plate and threadedly connected to the mounting part. A spring is sleeved around the second flange stud, and the spring is located between the baffle and the mounting part. The first support plate is located between one end of the second flange stud and the baffle.

[0009] Optionally, one end of the sliding column is provided with a sliding guide, which is slidably connected to the sliding groove, and the other end of the sliding column is provided with a limiting part, which is used to slide and limit the clamping member.

[0010] Optionally, the positioning module includes a first flange stud and a guide positioning component. The first flange stud extends vertically through the slide groove. One end of the first flange stud protrudes from the bottom surface of the first support plate, and the other end protrudes from the surface of the first support plate and is connected to the guide positioning component. The guide positioning component is slidably connected to the slide groove and is used to position the impeller-shaped workpiece.

[0011] Optionally, the guide positioning component is cylindrical, with a positioning contact surface at the top for positioning the impeller-like workpiece, and a notch on the side for sliding cooperation with the slide groove.

[0012] Optionally, the clamping module and the positioning module are arranged at intervals, and they are respectively located in different slides.

[0013] Optionally, the second clamping module includes a clamping disc and a support rod. One end of the support rod is threaded to the center of the first support disc, and the clamping disc is fixed to the other end of the support rod. The support rod and the first support disc are concentrically arranged.

[0014] Optionally, the support module further includes a second support plate, which is arranged parallel to and spaced apart from the first support plate, and the first support plate and the second support plate are connected by a column.

[0015] The beneficial effects of this multi-purpose clamping fixture are as follows: The first support plate directly supports the impeller-shaped workpiece. Combined with the positioning module that can slide radially along the slide groove, it enables positioning of impeller-shaped workpieces of different models and specifications before clamping. Then, based on the actual shape and requirements of the impeller-shaped workpiece, at least one of the first and second clamping modules is used to clamp the workpiece. When the first clamping module is in operation, it can be radially moved to a suitable position along the slide groove for impeller-shaped workpieces of different specifications, thereby achieving radial clamping of the impeller-shaped workpiece. For example, it can press the inner or outer ring of the impeller-shaped workpiece against the first support plate. The first clamping module can clamp the center of different types and thicknesses of impeller-type workpieces by moving along the thickness direction of the workpiece. For example, it can clamp the center of the impeller-type workpiece vertically and press it against the surface of the first support plate. That is, for different types and specifications of impeller-type workpieces, the first clamping module and the second clamping module can work together with the first support plate, or they can work together with the first support plate alone. In the radial direction, the first clamping module can move with the slide to achieve a large range of unidirectional or bidirectional clamping. In the vertical direction, the second clamping module can achieve blind clamping and blind positioning. Attached Figure Description

[0030] Reference Figure 1 , Figure 2 and Figure 3 As shown in the figure, this utility model embodiment proposes a multi-purpose clamping fixture for clamping impeller-type workpieces 6. The multi-purpose clamping fixture includes a support module 1, a positioning module 4, and a clamping module. The support module 1 includes a first support plate 11 for supporting the impeller-type workpiece 6. The first support plate 11 has a plurality of sliding grooves 2 spaced circumferentially, and each sliding groove 2 is arranged radially along the first support plate 11. The positioning module 4 is disposed in the sliding groove 2 and configured to slide along the sliding groove 2. Module 4 exposes the first support plate 11 and is used to position the impeller-shaped workpiece 6. The clamping module includes a first clamping module 5 and / or a second clamping module 3. The first clamping module 5 is disposed in the slide groove 2 and configured to slide along the slide groove 2. The first clamping module 5 is used to radially clamp the impeller-shaped workpiece 6. The second clamping module 3 is disposed at the center of the first support plate 11 and is configured to move along the thickness direction of the impeller-shaped workpiece 6. The second clamping module 3 is used to vertically clamp the impeller-shaped workpiece 6.

[0031] Specifically, when processing impeller-type workpieces 6, the processing requirements for different models and specifications of impeller-type workpieces 6 are not entirely the same. Therefore, the corresponding tooling needs to be compatible with the diverse impeller-type workpieces 6. Before processing, the first support plate 11 is generally suspended and fixed for easy operation. The impeller-type workpiece 6 is first placed on the first support plate 11, which can directly support the impeller-type workpiece 6, such as supporting its bottom end surface, so that the impeller-type workpiece 6 is placed concentrically with the first support plate 11 as much as possible. Then, the positioning module 4 is moved radially along the slide groove 2, so that the positioning module 4 can contact the impeller-type workpiece 6 through its protruding part, such as cooperating with the positioning hole in the bottom end surface of the impeller-type workpiece 6, or multiple positioning modules 4 can initially surround the impeller-type workpiece 6 in the center to prevent displacement, thereby achieving positioning before clamping. Then, according to the actual shape and actual requirements of the impeller-type workpiece 6, at least one of the first clamping module 5 and the second clamping module 3 is used to clamp the impeller-type workpiece 6. Among them, when the first clamping module 5 is in action, it is used to clamp different impeller-type workpieces 6. The bladed disk workpiece 6 can be moved radially along the slide groove 2 to a suitable position, thereby achieving radial clamping of the bladed disk workpiece 6. Since the bladed disk workpiece 6 is a bladed disk part with an overall ring structure, it has an inner ring and an outer ring. The first clamping module 5 can clamp the bladed disk workpiece 6 radially, for example, pressing the inner ring or outer ring position of the bladed disk workpiece 6 against the surface of the first support plate 11. The second clamping module 3 can move along the thickness direction of the bladed disk workpiece 6, thereby clamping the center part of bladed disk workpieces 6 of different models and specifications and thicknesses. For example, it can act vertically on the center position of the bladed disk workpiece 6, pressing the bladed disk workpiece 6 against the surface of the first support plate 11. Therefore, for bladed disk workpieces 6 of different models and specifications, the first clamping module 5 and the second clamping module 3 can work simultaneously with the first support plate 11 to achieve stable clamping, or they can work independently with the first support plate 11 to achieve stable clamping of the bladed disk workpiece 6.

[0032] In this embodiment, the first support plate 11 can directly support the impeller-shaped workpiece 6. Combined with the positioning module 4, which can slide radially along the slide groove 2, positioning of impeller-shaped workpieces 6 of different models and specifications before clamping can be achieved. Then, based on the actual shape and requirements of the impeller-shaped workpiece 6, at least one of the first clamping module 5 and the second clamping module 3 is used to clamp the impeller-shaped workpiece 6. When the first clamping module 5 is in operation, it can be radially moved to a suitable position along the slide groove 2 for impeller-shaped workpieces 6 of different specifications, thereby achieving radial clamping of the impeller-shaped workpiece 6. For example, by pressing the inner or outer ring position of the impeller-shaped workpiece 6 against the surface of the first support plate 11. The second clamping module 3, being able to move along the thickness direction of the impeller-type workpiece 6, can clamp the center of impeller-type workpieces 6 of different models and specifications and thicknesses. For example, it can act vertically on the center of the impeller-type workpiece 6, pressing the impeller-type workpiece 6 against the surface of the first support plate 11. That is, for impeller-type workpieces 6 of different models and specifications, the first clamping module 5 and the second clamping module 3 can work simultaneously with the first support plate 11, or they can work independently with the first support plate 11. In the radial direction, the first clamping module 5 can move with the slide groove 2 to achieve a large range of unidirectional or bidirectional clamping. In the vertical direction, the second clamping module 3 can achieve blind clamping and blind positioning.

[0033] The impeller-type workpiece 6 in this utility model generally includes integral impeller-type parts, disc shaft-type parts, tire mold-type parts, disc drum-type parts, casing-type parts, and short shaft-type (shaft diameter) parts. The multi-purpose clamping fixture of this utility model can achieve seamless switching for impeller-type workpieces 6 of different models and specifications, greatly reducing the idle time of equipment caused by tooling adjustments, improving the overall equipment utilization rate of the production line, and reducing the production preparation cycle.

[0034] like Figure 4 and Figure 5 As shown, in an optional embodiment of this utility model, the first clamping module 5 includes two clamping units arranged radially opposite to each other along the first support plate 11. Each clamping unit includes a second flange stud 51, a baffle 52, a clamping member 54, and a sliding column 56. The sliding column 56 is slidably connected to the sliding groove 2. The clamping member 54 is slidably sleeved on the sliding column 56. The second flange stud 51 is disposed in the sliding groove 2 and threadedly connected to the clamping member 54. The baffle 52 is sleeved on the second flange stud 51 and elastically connected to the clamping member 54. The baffle 52 is used to abut against the surface of the first support plate 11. In the two clamping units, the clamping member 54 of one clamping unit is used to clamp the impeller-like workpiece 6 radially inward, and / or the clamping member 54 of the other clamping unit is used to clamp the impeller-like workpiece 6 radially outward.

[0035] Specifically, the first clamping module 5 includes two clamping units: an inner clamping unit (closer to the center of the first support plate 11) and an outer clamping unit (farther from the center of the first support plate 11). After the impeller-shaped workpiece 6 is positioned, the inner clamping unit (the other clamping unit) slides inward to a suitable position, thereby clamping the inner ring of the impeller-shaped workpiece 6. In conjunction with the supporting effect of the first support plate 11, by tightening the second flange stud 51, the clamping member 54 slides relative to the sliding post 56, changing the distance between the baffle 52 and the surface of the first support plate 11. The distance between the clamping member 54 and the surface of the first support plate 11 also changes accordingly, pressing the inner ring portion of the impeller-shaped workpiece 6 against the first support plate 11. Figure 9 As shown; the working principle of the outer clamping unit (one of the clamping units) is the same as that of the inner clamping unit, which can clamp the bladed disk workpiece 6 radially inward. It should be noted that the two clamping units can work simultaneously to achieve stable clamping, or they can work alone, or at least work in conjunction with the second clamping module 3 to achieve stable clamping of the bladed disk workpiece 6.

[0036] like Figure 5 As shown, in an optional embodiment of the present invention, the clamping member 54 includes a mounting part 541 and a clamping part 542 that are fixedly connected. The mounting part 541 is threadedly connected to the second flange stud 51 and slidably connected to the sliding stud 56. The clamping part 542 is used to press the bladed disk-like workpiece 6 against the surface of the first support disk 11. The clamping parts 542 of the two clamping units are arranged opposite to each other.

[0037] Specifically, the mounting part 541 connects with the second flange stud 51 and the sliding stud 56, and the clamping part 542 interacts with the impeller-like workpiece 6, such as... Figure 9 In the middle, the inner clamping unit presses the inner ring position of the bladed disk workpiece 6 against the surface of the first support plate 11 (at this time, the outer clamping unit, that is, the clamping unit farther from the center, does not work, and the inner clamping unit can be used in conjunction with the second clamping module 3). The clamping parts 542 of the two clamping units are arranged opposite to each other, that is, the clamping surfaces of the clamping parts 542 are both set relative to the bladed disk workpiece 6 and always act on the bladed disk workpiece 6. In some cases, such as in order to simultaneously achieve clamping of the inner ring position and the outer ring position of the bladed disk workpiece 6, the two clamping units can work at the same time to achieve stable clamping.

[0038] Of course, in other cases, when faced with a suitable shape of the bladed disk workpiece 6, the outer clamping unit and the second clamping module 3 can be used together. In the actual processing, different clamping units and the second clamping module 3 can be selected according to the actual situation.

[0039] like Figure 1 , Figure 3 and Figure 4 As shown, in an optional embodiment of this utility model, the second flange stud 51 vertically penetrates the slide groove 2, one end of the second flange stud 51 protrudes from the bottom surface of the first support plate 11, and the other end protrudes from the surface of the first support plate 11 and is threadedly connected to the mounting part 541. A spring 53 is sleeved around the second flange stud 51, and the spring 53 is located between the baffle 52 and the mounting part 541. The first support plate 11 is located between one end of the second flange stud 51 and the baffle 52.

[0040] Specifically, the slide 2 is a through groove, and the second flange stud 51 extends from the bottom to the top of the first support plate 11. Since the baffle 52 abuts against the surface of the first support plate 11, and a spring 53 is sleeved around the second flange stud 51, the relative distance between the baffle 52 and the mounting part 541 can be changed by screwing one end (bottom end) of 81. This changes the clamping distance between the clamping part 542 and the surface of the first support plate 11, thereby enabling elastic clamping or release of the impeller-type workpiece 6. In another case, by maintaining the distance between the clamping part 542 of the clamping member 54 and the surface of the first support plate 11, and by having the clamping part 542 of the clamping unit body approach the end face of the impeller-type workpiece 6, maintaining contact with the inner ring position and / or outer ring position of the impeller-type workpiece 6, multiple second clamping modules 3 can tightly hold the position of the positioning module 4 in place, thereby achieving clamping. In this case, generally two clamping units are used in conjunction, or one clamping unit is used in conjunction with the second clamping module 3 to achieve a stable clamping effect.

[0041] It is understandable that when each clamping unit operates independently, or when not all three (two clamping units and the second clamping module 3) operate simultaneously, the preload of the corresponding spring 53 can be set differently, meaning that the second flange stud 51 can be screwed to different depths.

[0042] like Figure 4 As shown, in an optional embodiment of the present invention, one end of the sliding column 56 is provided with a sliding guide 55, which is slidably connected to the sliding groove 2, and the other end of the sliding column 56 is provided with a limiting part, which is used to slide and limit the clamping member 54.

[0043] Specifically, the side of the sliding guide 55 is provided with a notch along the direction of the slide groove 2. The sliding guide 55 slides with the slide groove 2 through the notch, so that the entire positioning module 4 can slide along the slide groove 2 under the action of external force. The other end of the slide column 56 is provided with a limiting part, which is used to prevent the clamping part 54 from sliding out. Thus, when the second flange stud 51 is tightened, the clamping part 54 can slide relative to the slide column 56, so that the impeller-type workpiece 6 can be firmly clamped and the relative rotation of the clamping part 54 can be avoided.

[0044] like Figure 6 As shown, in an optional embodiment of this utility model, the positioning module 4 includes a first flange stud 41 and a guide positioning member 42. The first flange stud 41 extends vertically through the slide groove 2. One end of the first flange stud 41 protrudes from the bottom surface of the first support plate 11, and the other end protrudes from the surface of the first support plate 11 and is connected to the guide positioning member 42. The guide positioning member 42 is slidably connected to the slide groove 2 and is used to position the impeller-shaped workpiece 6.

[0045] Specifically, the first flange stud 41 extends from the bottom of the first support plate 11 to the top of the first support plate 11. By operating from one end (bottom end) of the first flange stud 41, the positioning module 4 can be moved, thereby positioning the impeller-like workpiece 6 through the guide positioning member 42. Specifically, during positioning, multiple positioning modules 4 are moved to appropriate positions along the slide groove 2, thereby causing the guide positioning member 42 to abut against the outer position of the inner ring of the impeller-like workpiece 6, or to achieve positioning by cooperating with the positioning part (such as the positioning hole) on the impeller-like workpiece 6. Multiple positioning modules 4 can be set to cooperate to achieve positioning.

[0046] like Figure 1 , Figure 6 As shown, in an optional embodiment of the present invention, the guide positioning member 42 is cylindrical, the top of the guide positioning member 42 is provided with a positioning contact surface for positioning the impeller-like workpiece 6, and the side of the guide positioning member 42 is provided with a notch that slides with the slide groove 2.

[0047] Specifically, the guide positioning component 42 has a positioning contact surface on its top, that is, the top or side of the cylindrical guide positioning component 42 has a positioning contact surface. By moving the positioning module 4, the positioning contact surface can be made to contact the outer side of the inner ring of the impeller-like workpiece 6, thereby realizing the clamping and positioning of the impeller-like workpiece 6. In another case, the impeller-like workpiece 6 is generally provided with a corresponding positioning hole. The guide positioning component 42 is adapted to the positioning hole, so that the impeller-like workpiece 6 is positioned in the center position, keeping it concentric with the first support plate 11, and then facilitating clamping. The side of the guide positioning component 42 has a notch along the direction of the slide groove 2. The guide positioning component 42 slides with the slide groove 2 through the notch, so that the entire positioning module 4 can slide along the slide groove 2 under the action of external force. Figure 9 In this process, multiple positioning modules 4 cooperate to abut against the outer side of the inner ring of the impeller-shaped workpiece 6, thereby achieving positioning.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, in an optional embodiment of this utility model, the clamping module and the positioning module 4 are arranged at intervals and are respectively located in different slide grooves 2.

[0049] Specifically, by placing the clamping modules in different slides 2, the distribution of the points of application for the impeller-shaped workpiece 6 can be ensured to be relatively uniform, thereby facilitating uniform force distribution and ensuring clamping stability. Figure 2 As can be seen, a positioning module 4 is set every two second clamping modules 3.

[0050] like Figure 7 and Figure 8 As shown, in an optional embodiment of the present invention, the second clamping module 3 includes a clamping disc 31 and a support rod 32. One end of the support rod 32 is threadedly connected to the center of the first support disc 11, and the clamping disc 31 is fixed to the other end of the support rod 32. The support rod 32 and the first support disc 11 are concentrically arranged.

[0051] Specifically, one end of the support rod 32 is the head of a stud, and the other end extends to the position of the first support plate 11. The first support plate 11 is provided with a threaded sleeve that engages with the threaded part of the support rod 32. By screwing the head at one end, the clamping plate 31 can be pressed down, thereby achieving clamping and fixing of the impeller-type workpiece 6, which is easily fixed by pressing down on the end face. When it is necessary to release the clamp, the operation can be reversed. For example, in Figure 9 In this system, the end face clamping and inner ring position clamping of the bladed disk type workpiece 6 can be achieved.

[0052] like Figure 1 and Figure 8As shown, in an optional embodiment of the present invention, the support module 1 further includes a second support plate 13, which is arranged parallel to and spaced apart from the first support plate 11. The first support plate 11 and the second support plate 13 are connected by a column 12.

[0053] Specifically, by setting up the second support plate 13 and the column 12, the first support plate 11 and the second support plate 13 are connected by the column 12. While ensuring rigidity, the positioning height is increased and the operating space is expanded. The first flange stud 41 and the second flange stud 51 can be screwed between the first support plate 11 and the column 12, thereby facilitating positioning and clamping.

[0054] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features of the present invention.

[0055] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
