Description

Technical Field

[0001] The invention belongs to the technical field of machining tooling, and in particular relates to a clamping tooling and a clamping method for casing parts. Background Art

[0002] In the aerospace industry, the machining of thin-walled casing-like workpieces is extremely challenging, especially when the material is difficult to machine, such as high-temperature alloys or titanium alloys. There are often two main difficulties: first, vibration is likely to occur during machining; second, the release of stress after the tooling is removed can easily lead to structural deformation. In order to solve these problems, auxiliary support tooling is usually required.

[0003] In the prior art, wax filling is often used to provide internal support for thin-walled structures such as casings to control vibration and deformation. However, this method is only applicable to machining of some parts to be machined, and structural deformation often occurs during wax removal after machining.

[0004] Therefore, there is an urgent need to propose a clamping tool and a clamping method specifically for the parts to be processed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to at least solve how to reduce the vibration of the parts to be processed during the processing and the deformation after the tooling is removed. This purpose is achieved by the following technical solutions: The first aspect of the present invention provides a clamping tool for receiver parts, comprising: Base; A plurality of fixing components, each of which is connected to the base, and the fixing components are used to fix the bottom of the part to be processed and the base; A locking assembly, the locking assembly is used to be connected to the top of the part to be processed, the locking assembly comprises a plurality of first wire-passing members, and the plurality of first wire-passing members are arranged at intervals along the circumference of the part to be processed; A plurality of pulling assemblies, wherein the plurality of pulling assemblies are arranged on the base at intervals around the installation position of the part to be processed, and the pulling assemblies include a second wire-passing member; An adjusting component, the adjusting component is arranged on the base, the adjusting component comprises a third wire-passing member, and the third wire-passing member can move relative to the base; A traction rope passes through the first wire passing piece, the second wire passing piece and the third wire passing piece, and ends of the traction rope are connected to form a closed loop.

[0006] The above-mentioned receiver-type parts clamping tool fixes the bottom and base of the part to be processed by a fixing component. By connecting the locking component to the top of the part to be processed, the first wire-passing piece is set at an appropriate position of the part to be processed according to the shape characteristics of the part to be processed, and accordingly, a pulling component is set at an appropriate position on the bottom plate, so that the traction rope passes through multiple first wire-passing pieces and multiple second wire-passing pieces in a predetermined manner, so that the radial forces of the part to be processed offset each other, and the direction of the resultant force is vertically downward. Since the radial forces of the part to be processed offset each other, the clamping and removal of the receiver-type parts clamping tool will not affect the stress characteristics of the part to be processed, thereby avoiding the deformation of the part to be processed due to the clamping of the tool, and since the part to be processed is subjected to vertical downward pressure, the vibration amplitude can be reduced. According to the natural mode of the part to be processed, the position of the third wire-passing piece in the moving adjustment component is changed to change the tension on the traction rope, so that the traction rope provides a suitable pressure for the part to be processed. At the same time, the vibration generated during the processing of the part to be processed is attracted to the traction rope, thereby reducing the modal frequency of the part to be processed. By reducing the modal frequency of the parts to be processed, the main excitation frequency range in the processing process can be avoided, thereby greatly reducing the amplitude of the parts to be processed, achieving the effect of controlling the vibration of the parts to be processed. In addition, each component in the clamping tooling for the casing parts adopts a modular design, which is easy to assemble and disassemble, and can quickly change different traction rope passage modes according to the needs of use.

[0024] The above-mentioned receiver-type parts clamping tool fixes the bottom of the part to be processed 10 and the base 100 through the fixing component 200.

By reducing the modal frequency of the part 10 to be processed, the main excitation frequency range during the processing can be avoided, thereby greatly reducing the amplitude of the part 10 to be processed, and achieving the effect of controlling the vibration of the part 10 to be processed. In addition, each component in the clamping tooling of the casing parts adopts a modular design, which is simple to assemble and disassemble, and can quickly change different traction rope 600 travel modes according to the needs of use.

The locking handle 573 is fixedly sleeved on the locking bolt 572, and the bottom of the locking bolt 572 passes through the adjustment portion and is connected to the locking nut 574. When it is necessary to fix the position of the adjustment base 540, the locking handle 573 is rotated to lock the locking bolt 572 and the locking nut 574, and at the same time, the adjustment gap is reduced, and the clamping block 571 clamps the transmission rod 530, thereby preventing the screw from rotating.

[0036] Further, the adjustment assembly 500 also includes an adjustment platform 550, which is fixedly connected to the adjustment base 540, and the third wire-passing member 510 is connected to the adjustment platform 550. Optionally, the adjustment platform 550 is provided with a plurality of sockets for inserting the third wire-passing member 510, and the sockets in appropriate positions can be selected according to the use requirements. Optionally, the adjustment platform 550 is fixedly connected to the adjustment base 540 by bolts. Optionally, the third wire-passing member 510 includes a slip ring and a connecting screw.

[0037] Fig.10The figure schematically shows a top view of a receiver-type parts clamping tool in a use state according to an embodiment of the present invention. Fig.11 The top view of the clamping tool for the receiver parts according to the embodiment of the present invention in another use state is schematically shown. Further, the traction rope 600 includes a first section 610 and a second section 620. The first section 610 is passed through the first wire-passing member 320 and the second wire-passing member 410, and the second section 620 is passed through the third wire-passing member 510. The first end of the first section 610 and the first end of the second section 620 are connected through a first dynamometer 601, and the second end of the first section 610 and the second end of the second section 620 are connected through a second dynamometer 602. The first dynamometer 601 and the second dynamometer 602 are used to measure the tension on the traction rope 600. See Fig.10 and Fig.11 The traction rope 600 includes a first section 610 and a second section 620. The first section 610 is passed through the first wire-passing member 320 and the second wire-passing member 410, and the second section 620 is passed through the third wire-passing member 510. The first end of the first section 610 and the first end of the second section 620 are connected through a first dynamometer 601, and the second end of the first section 610 and the second end of the second section 620 are connected through a second dynamometer 602. The first dynamometer 601 and the second dynamometer 602 are used to measure the tension of the traction rope 600. It can be understood that the first section 610, the first dynamometer 601, the second section 620 and the second dynamometer 602 are connected end to end to form a closed loop, so that the tension of the traction rope 600 can be adjusted by adjusting the position of the third wire-passing member 510, and the force balance of each part of the traction rope 600 can be adjusted by moving the positions of the first wire-passing member 320, the second wire-passing member 410 or other components. Optionally, in order to avoid interference between the first dynamometer 601 and the second dynamometer 602, a pulling assembly 400 is added on both sides of the adjustment assembly 500 to pull a distance between the first dynamometer 601 and the second dynamometer 602. Preferably, the traction rope 600 is a steel wire rope, which can withstand a large tensile force and has a small friction force. The first wire member 320, the second wire member 410 and the third wire member 510 are all made of a material with a small friction coefficient, such as steel, so that the friction between the traction rope 600 and the slip ring can be ignored.

[0038] according to Fig.10 and Fig.11It can be seen that the angle of the traction rope 600 can be changed by changing the distance between the geometric center of the pulling assembly 400 and the bottom plate 430. It can be understood that the way the traction rope 600 passes through is related to the number and position of the wire-passing pieces. In this embodiment, there are 8 first wire-passing pieces 320, and each first wire-passing piece 320 is provided with a second wire-passing piece 410 on both sides, and the second wire-passing pieces 410 on both sides are symmetrically arranged, and the traction rope 600 in the circumferential direction of the part 10 to be processed is centrally symmetrically distributed about the center of the part 10 to be processed, so that the radial forces of the part 10 to be processed offset each other, and the direction of the resultant force is vertically downward. In this case, the part 10 to be processed will not undergo structural deformation, and at the same time, the resultant force can effectively reduce the vibration amplitude during the production process, and the vibration can be attracted to the traction rope 600. The magnitude of the resultant force can be adjusted by the third wire-passing member 510. Specifically, when the length of the traction rope 600 remains unchanged, the tension on the traction rope 600 can be reduced by moving the third wire-passing member 510 toward the part to be processed 10, thereby reducing the pressure on the part to be processed 10. By moving the third wire-passing member away from the part to be processed 10, the tension on the traction rope 600 can be increased, thereby increasing the pressure on the casing parts.

[0039] The technical solution also provides a method for clamping receiver parts. The method is based on the receiver parts clamping tool in the above technical solution. The receiver parts clamping tool includes a first dynamometer 601 and a second dynamometer 602. The traction rope 600 includes a first section 610 and a second section 620. The receiver parts clamping method includes the following steps: S100, placing the part 10 to be processed on the base 100, fixing the part 10 to be processed and the base 100 with the fixing assembly 200, connecting the locking assembly 300 to the part 10 to be processed, passing the first section 610 through the first wire-passing member 320 and the second wire-passing member 410, passing the second section 620 through the third wire-passing member 510, connecting the first end of the first section 610 and the first end of the second section 620 with the first dynamometer 601, and connecting the second end of the first section 610 and the second end of the second section 620 with the second dynamometer 602; S200, adjusting the tension of the traction rope 600 by moving the third wire-passing member 510, so that the readings of the first dynamometer 601 and the second dynamometer 602 are both within a preset range; S300, adjusting the locking assembly 300, the pulling assembly 400 and the pulling rope 600; S400 , repeat S200 and S300 until the readings of the first dynamometer 601 and the second dynamometer 602 are the same and within a preset range.

[0040] In order to achieve a better effect of controlling vibration and deformation, a suitable type of traction rope 600 is selected through simulation calculation, and the preset range should be calculated according to the modal frequency of the part 10 to be processed and the characteristics of the traction rope 600 and other parameters. It can be understood that a traction rope 600 with a larger diameter can bear a larger load, but the hardness and internal stress are also greater, which leads to greater friction between the traction rope 600 and the wire passing part. Therefore, a traction rope 600 of appropriate thickness needs to be selected. Usually, the required diameter range of the traction rope 600 can be obtained through simulation calculation, and a more accurate diameter determination needs to be carried out in experiments or actual operations. In the selection of the model and preset range of the traction rope 600, the natural mode of the traction rope 600 should be close to the part 10 to be processed, forming a resonance effect, so that the vibration in the processing process is guided to the traction rope 600. Optionally, a broadband vibration absorber can be placed on the traction rope 600 to greatly eliminate these vibrations. The selection method of the traction rope 600 and the calculation method of the preset range are mature existing technologies in this field, and no further explanation is given here.

[0041] It can be understood that in an ideal state (the friction between the traction rope 600 and the line-passing member is zero), the readings on the first dynamometer 601 and the second dynamometer 602 are always the same, but in actual situations, due to the friction between the traction rope 600 and the line-passing member, the readings on the first dynamometer 601 and the second dynamometer 602 are prone to deviation. Therefore, after S200, S300 needs to be performed, that is, the readings of the first dynamometer 601 and the second dynamometer 602 are made the same by adjusting the locking assembly 300, the pulling assembly 400 and the traction rope 600. S200 and S300 are repeated until the readings of the first dynamometer 601 and the second dynamometer 602 are the same and within a preset range.

[0042] Exemplarily, in S300, the adjustment method includes: adjusting the locking belt 310 so that the locking belt 310 clamps the part to be processed 10 to ensure that the second wire-passing piece 410 is fixed on a certain circular contour of the part to be processed 10; adjusting the second wire-passing piece 410 so that the traction rope 600 is centrally symmetrically distributed about the center of the part to be processed 10 under the pulling of the third wire-passing piece 510; adjusting the model of the traction rope 600, such as replacing the traction rope 600 with a different diameter.

[0043] After S400 , the part 10 to be processed is processed, and S200 to S400 are repeated to keep the readings of the first dynamometer 601 and the second dynamometer 602 the same and within a preset range until the test is completed.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
