Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular to a tooling for machining the internal cavity of irregularly shaped components. Background Technology

[0002] like Figure 1 The diagram shows a structural schematic of a non-standard component 1. The workpiece includes a frame 11, with two top lugs 111 on the top and two bottom lugs 112 on the bottom side. Both the top lugs 111 and the bottom lugs 112 have lug holes. A curved beam 12 is provided on one side of the frame 11, and a window 113 is provided in the middle of the frame 1. Ribs are provided on the side walls of the frame on both sides of the window 113. When machining the inner cavity of the non-standard component 1, the tool needs to enter the inner cavity through the window 113 in the middle of the frame 11. Traditional fixtures cannot guarantee the stable clamping of the non-standard component. During the inner cavity machining process, the workpiece is prone to vibration, which affects the machining accuracy.

[0003] Therefore, a technical solution is needed to address the problem that irregularly shaped components are prone to vibration when the cutting tool enters through the window of the component for internal machining, making it difficult to guarantee machining accuracy. Utility Model Content

[0004] The purpose of this invention is to overcome the technical problem in the prior art that when the cutting tool enters the inner cavity of an irregularly shaped component through the window for machining, the irregularly shaped component is prone to vibration, making it difficult to guarantee machining accuracy. This invention provides a tooling for machining the inner cavity of an irregularly shaped component.

[0005] This utility model provides a tooling for machining the inner cavity of irregularly shaped components, including a base. The base is provided with a first limiting mechanism and a second limiting mechanism. A plurality of clamping mechanisms are provided between the first limiting mechanism and the second limiting mechanism, and the plurality of clamping mechanisms are respectively disposed on both sides of the base.

[0006] First limiting mechanism: includes two oppositely arranged first fixed seats, each first fixed seat is detachably provided with a first limiting shaft, and the two first limiting shafts are respectively used to connect the two top lugs of the irregular component;

[0007] Second limiting mechanism: includes a second fixed seat, on which a second limiting shaft is detachably provided, the second limiting shaft being used to connect the two bottom lugs of the irregularly shaped component;

[0008] The clamping mechanism includes a column, a clamping bolt, and a pressure plate. The pressure plate has a connecting hole, and the top of the column has a mounting screw hole. The clamping bolt passes through the connecting hole and connects to the mounting screw hole to clamp the pressure plate onto the stiffening plate on the side of the irregular component.

[0009] This utility model discloses a tooling for machining the inner cavity of an irregularly shaped component. In use, the top lug of the irregularly shaped component is placed near the first limiting mechanism. Two first limiting shafts pass through the two top lugs to limit the top of the irregularly shaped component. The two bottom lugs of the irregularly shaped component are located at the first limiting mechanism at the other end of the base. The bottom of the irregularly shaped component is limited by the first limiting shafts passing through the two bottom lugs. Then, several clamping mechanisms located on both sides of the base are used to clamp the ribs on the side of the irregularly shaped component, thereby achieving stable clamping of the irregularly shaped component without affecting the tool's entry from the window of the irregularly shaped component, thus improving the quality of machining the inner cavity of the irregularly shaped component.

[0010] Preferably, the top of the column is provided with a horizontal extension block, and the horizontal extension block is provided with a vertical support bolt, which can extend into the bottom surface of the pressure plate through the horizontal extension plate.

[0011] The clamping bolts clamp the reinforcing plate from the top, and the vertical support bolts clamp the reinforcing plate from the bottom, which enhances the stability of the clamping process and further reduces vibration during the processing of irregularly shaped components.

[0012] Preferably, the vertical support bolt is fitted with an anti-loosening nut, which is used to abut against the bottom surface of the transverse extension plate.

[0013] By adding anti-loosening nuts to the vertical support bolts, the vibration resistance of the vertical support bolts is improved, and the loosening of the vertical support bolts is prevented.

[0014] Preferably, the side of the column is provided with a transverse support bolt, which can pass through the column and abut against the side of the irregular component.

[0015] When the width of an irregularly shaped component is large, the clamping bolts tighten the upper stiffening plate of the component. However, the area between the upper stiffening plate and the base lacks support. By installing transverse support bolts in the middle of the column, which abut against the side of the irregularly shaped component, the overall stability of the component is enhanced.

[0016] Preferably, the bottom of the column is provided with a connecting seat, which is connected to the base by connecting bolts.

[0017] The clamping mechanism and the base are detachably connected. Before placing irregularly shaped components on the base, the clamping mechanism can be removed to avoid affecting the installation of the irregularly shaped components. During the processing of irregularly shaped components, the clamping mechanism that interferes with the tool can be removed and then installed after the processing of this part is completed, making the application of the clamping mechanism more flexible.

[0018] Preferably, one end of the base is provided with a boss, and the first limiting mechanism is disposed on the boss.

[0019] After the irregular component is placed on the base, there is a height difference between the axis of the top ear piece and the axis of the bottom ear piece. By installing the first limiting mechanism through the boss, the design height of the first fixed seat can be reduced and the structural stability of the tooling can be improved.

[0020] Preferably, a plurality of support components are provided between the boss and the second limiting mechanism, and the support components are used to abut against the irregularly shaped component.

[0021] Due to the height difference between the top and bottom ear pieces, a suspended area is formed between the frame and the base after the top and bottom ear pieces are fixed. By setting a support component on the top surface of the base to support the suspended part of the frame, the clamping stability of the irregular component is enhanced and the vibration during the processing of the irregular component is reduced.

[0022] Preferably, the support assembly includes a support rod and a support block. The top surface of the support block is provided with a fitting surface that matches the local shape of the irregular component. The bottom surface of the support block is provided with a mounting hole that matches the support rod. The support rod is provided with a threaded section, and a push nut is fitted on the threaded section. The push nut is used to push the support block to move along the height direction of the support rod.

[0023] On the one hand, before the irregular component is installed on the base, the support block can be lowered by pushing the nut, which can avoid interference and collision between the irregular component and the support block to a certain extent, making it easier to install the irregular component on the base. On the other hand, after the irregular component is installed on the base, if there is a deviation in the size of the irregular component or tooling, the support block can still be adjusted upward by pushing the nut and abut against the irregular component, ensuring stable support for the suspended part of the irregular component.

[0024] Preferably, the base has a support beam at the bottom, the support beam has a groove adapted to the shape of the curved beam, and the base has an avoidance groove at the top corresponding to the position of the support beam.

[0025] When the frame of the irregular component is located on the base, the curved beam on one side is suspended on one side of the base. By adding a support beam on one side of the base to place the curved beam, the curved beam is protected, and the potential damage and deformation during processing are reduced.

[0026] Preferably, the support beam is provided with a plurality of limiting components, which are arranged along the length of the support beam. Each limiting component includes two limiting seats, which are respectively disposed on both sides of the groove. A pressure block is connected to the limiting seat by a limiting bolt.

[0027] The bending beam of the irregular component is pressed tightly onto the support beam by the clamping block, which reduces the vibration during the processing of the bending beam.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] This utility model provides a machining fixture for the inner cavity of irregularly shaped components. By setting a first limiting mechanism and a second limiting mechanism on the base to fix the top and bottom lugs of the irregularly shaped component respectively, and then pressing the ribs on both sides of the irregularly shaped component by a number of pressing mechanisms on both sides of the base, the fixture can achieve stable clamping of the irregularly shaped component without affecting the tool entering from the window of the irregularly shaped component for inner cavity machining, reducing workpiece vibration during machining, and improving the machining quality of the irregularly shaped component.

[0045] Example 1

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, a tooling for machining the inner cavity of an irregularly shaped component includes a base 2. A first limiting mechanism 3 and a second limiting mechanism 4 are provided on the base 2. A plurality of clamping mechanisms 5 are provided between the first limiting mechanism 3 and the second limiting mechanism 4, and the plurality of clamping mechanisms 5 are respectively disposed on both sides of the base 2.

[0047] The first limiting mechanism 3 includes two opposing first fixed seats 31. The first fixed seats 31 are detachably provided with first limiting shafts 32. The two first limiting shafts 32 are respectively used to connect the two top lugs 111 of the irregular component 1. One of the first limiting shafts 32 is detachably provided with a flange at its end. The flange presses the top lugs 111 of the irregular component 1 against the side of the first fixed seat 31.

[0048] The second limiting mechanism 4 includes a second fixed base 41, on which a second limiting shaft 42 is detachably provided. The second limiting shaft 42 is used to connect the two bottom lugs 112 of the irregular component 1.

[0049] The clamping mechanism 5 includes a column 51, a clamping bolt 52, and a pressure plate 53. The pressure plate 53 is provided with a connecting hole, which is a waist-shaped hole. The top of the column 51 is provided with a mounting screw hole. The clamping bolt 52 passes through the connecting hole and connects to the mounting screw hole, thereby clamping the pressure plate 53 onto the stiffening plate on the side of the irregular component 1.

[0050] In use, the top lug 111 of the irregular component 1 is placed near the first limiting mechanism 3. The two first limiting shafts 32 pass through the two top lugs 111 respectively to limit the top of the irregular component 1. The two bottom lugs 112 of the irregular component 1 are located at the first limiting mechanism 3 at the other end of the base 2. The bottom of the irregular component 1 is limited by the first limiting shafts 32 passing through the two bottom lugs 112. Then, the side ribs of the irregular component 1 are pressed by several clamping mechanisms 5 located on both sides of the base 2, thereby achieving stable clamping of the irregular component 1. At the same time, it does not affect the tool from entering through the window 113 of the irregular component 1, thus improving the quality of machining of the inner cavity of the irregular component 1.

[0051] In one or more embodiments, a boss 21 and several support components 6 may be provided on one side of the base 2.

[0052] Boss 21: The first limiting mechanism 3 is set on the boss 21. After the irregular component 1 is placed on the base 2, there is a height difference between the axis of the top ear piece 111 and the axis of the bottom ear piece 112. By installing the first limiting mechanism 3 through the boss 21, the design height of the first fixed seat 31 can be reduced and the structural stability of the tooling can be improved.

[0053] Support component 6: Located between the boss 21 and the second support component 6, it supports the suspended portion between the irregular component 1 and the base 2, enhancing the clamping stability of the irregular component 1 and reducing vibration during the processing of the irregular component 1. The support component 6 includes a support rod 61 and a support block 62. The top surface of the support block 62 has a mating surface adapted to the local shape of the irregular component 1, and the bottom surface of the support block 62 has a mounting hole adapted to the support rod 61. The support rod 61 has a threaded section, and a push nut 63 is fitted on the threaded section. 3 is used to push the support block 62 to move along the height direction of the support rod 61. Before the irregular component 1 is installed on the base 2, the support block 62 can be lowered by pushing the nut 63, which can avoid interference and collision between the irregular component 1 and the support block 62 to a certain extent, and facilitate the installation of the irregular component 1 on the base 2. After the irregular component 1 is installed on the base 2, if there is a deviation in the size of the irregular component 1 or the tooling, the support block 62 can still be adjusted upward by pushing the nut 63 and abut against the irregular component 1 to ensure stable support of the suspended part of the irregular component 1.

[0054] In one or more embodiments, the column 51 may also be provided with a vertical support bolt 54, a horizontal support bolt 55, and a connecting seat 56.

[0055] Vertical support bolt 54: The top of the column 51 is provided with a horizontal extension block, and the horizontal extension block is provided with a vertical support bolt 54. The vertical support bolt 54 can extend into the bottom surface of the pressure plate 53 through the horizontal extension plate. The vertical support bolt 54 presses the stiffening plate from the bottom of the stiffening plate, which enhances the stability of the pressing process and further reduces the vibration during the processing of the irregular component 1. The vertical support bolt 54 is fitted with an anti-loosening nut, which is pressed against the bottom surface of the horizontal extension block to improve the vibration resistance of the vertical support bolt 54 and prevent the vertical support bolt 54 from loosening.

[0056] Horizontal support bolt 55: Located in the middle of column 51, the horizontal support bolt 55 can pass through column 51 and abut against the side of irregular component 1. When the width of irregular component 1 is large, the clamping bolt 52 clamps the upper stiffening plate of irregular component 1. However, the part between the upper stiffening plate and the base 2 lacks support. By setting the horizontal support bolt 55 in the middle of column 51 and abutting against the side of irregular component 1, the overall stability of irregular component 1 is strengthened.

[0057] Connecting seat 56: Located at the bottom of column 51, connecting seat 56 is connected to base 2 by connecting bolt 57, realizing the detachable connection between clamping mechanism 5 and base 2. Before placing irregular component 1 on base 2, clamping mechanism 5 can be removed to avoid affecting the installation of irregular component 1. During the processing of irregular component 1, clamping mechanism 5 that interferes with the tool can be removed and installed after the processing of this part is completed, making the application of clamping mechanism 5 more flexible.

[0058] Example 2

[0059] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, in this embodiment, the difference from embodiment 1 is that the base 2 is provided with a support beam 7 at the bottom, the support beam 7 is provided with a groove adapted to the shape of the curved beam 12, and the top of the base 2 is provided with an avoidance groove 22 corresponding to the position of the support beam 7.

[0060] In this embodiment, when the frame 11 of the irregular component 1 is located on the base 2, the curved beam 12 on one side of the base 2 is suspended on one side of the base 2. By adding a support beam 7 on one side of the base 2 to place the curved beam 12, the curved beam 12 is protected, and the potential damage to the curved beam 12 and the deformation generated during the processing are reduced.

[0061] In one or more embodiments, a plurality of limiting components 8 may be provided on the support beam 7, and the plurality of limiting components 8 are arranged along the length of the support beam 7.

[0062] Limiting component 8: includes two limiting seats 81, which are respectively disposed on both sides of the groove. The limiting seats 81 are connected to pressure blocks 82 by limiting bolts 83. The pressure blocks 82 press the curved beam 12 of the irregular component 1 onto the support beam 7 to reduce the vibration of the curved beam 12 during processing.

[0063] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
