Description

Technical Field

[0001] This invention relates to the field of assembly and processing technology, and in particular to a processing device for impact deformation. Background Technology

[0002] Applying impact force to deform the workpiece is a common assembly and locking method in aerospace products. This method controls reliable locking between workpieces by causing plastic deformation of the machined holes in the components, and is often used for limiting steel balls in elastic unlocking mechanisms and locking the outer ring of bearings in confined spaces.

[0003] These types of workpieces have high mechanical properties, compact structural dimensions, and small operating space. After assembly, they require flexible operation and flexible and reliable unlocking and locking. When processing these workpieces, it is necessary to apply impact force evenly to avoid uneven force application that could damage the workpiece structure. At the same time, it is necessary to control the force transmission path so that the impact force can be effectively transmitted to the workpiece, causing the workpiece's machining holes to produce the required plastic deformation.

[0004] Currently, such workpieces are usually processed manually by technicians using impact tools. It is difficult to maintain uniform force during the processing, and the force transmission path is also difficult to control. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide an impact deformation processing device to solve the problem of difficulty in controlling the uniformity of impact force and the force transmission path during the application of impact force in the prior art.

[0006] The objective of this invention is mainly achieved through the following technical solutions:

The hand crank is connected to the drive component, and a driving force is provided to the drive component by rotating the hand crank. The drive component is connected to the force transmission component, and the force transmission component is connected to the hammer body. The drive component transmits the driving force to the hammer body through the force transmission component, thereby causing the hammer body to move up and down along the inner wall of the outer casing.

[0022] Furthermore, the force transmission unit also includes a force transmission column, which includes a hammer head, a limiting rod, and a positioning head. The positioning head is used to limit the deformation of the machined hole.

[0023] Furthermore, the positioning component includes a guide post, which comprises a column body, an inlet section, and a guide head, the guide head being used to adjust the position of the element.

The washer is fixed to the inner wall of the outer casing.

[0032] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0033] (1) The impact deformation processing device provided by the present invention, during the process of applying impact force, since the weight of the hammer body is a fixed value, when the limiting pin slides upward along the slide groove to the top of the slide groove, the deformation of the first spring caused by the extrusion of the outer shell is fixed. Therefore, during the process of applying impact force, the impact force generated by the hammer body hitting the force transmission column downward each time is a fixed value, which realizes the uniform application of impact force and prevents the impact force from suddenly being too large or too small, thus damaging the structure of the component.

[0034] (2) The impact deformation processing device provided by the present invention has a fixed weight of the hammer body during the process of applying impact force. When the hammer body moves to the highest point, the stretch of the second spring is a fixed value. Therefore, during the process of applying impact force, the impact force generated by the hammer body hitting the force transmission column downward each time is a fixed value, which realizes the uniform application of impact force and prevents the impact force from suddenly being too large or too small, thus damaging the structure of the component.

[0035] (3) The impact deformation processing device provided by the present invention transmits the impact force to the processing hole through the force transmission column and controls the deformation of the processing hole through the positioning head. In the process of applying the impact force to deform the processing hole, the force transmission path and deformation are controlled, preventing the force transmission path from deviating and causing the processing hole to fail to achieve the required deformation.

[0036] (4) The impact deformation processing device provided by the present invention drives the movement of the hammer body by shaking the hand crank handle, so that the hammer body repeatedly strikes the force transmission column to provide impact force. It is simple to operate and easy to control, providing convenience for technicians in actual operation.

[0037] (5) The impact deformation processing device provided by the present invention can correct the position of the component in the placement groove by setting guide columns, which makes it easier for technicians to adjust the position of the component in actual operation and make the force transmission path more accurate.

[0038] (6) The impact deformation processing device provided by the present invention keeps the hammer body in a fixed position during the installation process by setting a limiting groove, so as to prevent the hammer body from moving up and down and interfering with the installation of the force application unit.

[0039] (7) The impact deformation processing device provided by the present invention can measure the displacement of the positioning head by setting a vernier and a scale when the processing state of the processing hole cannot be seen, thereby intuitively reflecting the impact of the positioning head on the processing hole, and making it easy for the operator to estimate the deformation of the processing hole caused by the impact force based on the displacement of the positioning head.

Detailed Implementation

[0058] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and are used together with the invention to illustrate the principles of the invention.

[0059] Example 1

[0060] This embodiment provides a processing device for impact deformation, such as... Figure 3 As shown, this is used to machine the machining hole 51 on component 5 into the shape of the deformed hole 52. For example... Figures 1-2 As shown, the impact deformation processing device provided in this embodiment includes a base 1, a clamping assembly 2, a positioning assembly 3, and a force application unit 4. The base 1 is connected to the clamping assembly 2 through the positioning assembly 3. The positioning assembly 3 is used to connect the base 1 and the clamping assembly 2, as well as the force application unit 4 and the clamping assembly 2. The positioning assembly 3 can also guide the position of the element 5. The clamping assembly 2 is used to clamp the element 5 to be processed. The force application unit 4 is used to apply the impact force required to deform the processing hole 51 and limit the deformation of the processing hole 51, thus processing the processing hole 51 into the shape of the deformable hole 52.

[0061] like Figure 4As shown, the base 1 is provided with a placement groove 11, a first side slot 12, a limiting hole 13, and a fixing hole 14. The placement groove 11 is used to place the component 5 to be processed, such as... Figure 5 As shown, the machining hole 51 faces the clamping assembly 2, and the space in the placement groove 11 is adapted to the size of the component 5 to be machined.

[0062] like Figure 2 As shown, the positioning assembly 3 includes a wing bolt 31, a guide 32, and a limiting rod 34. The first side slot 12 is provided on both sides of the base 1 and is connected to the wing bolt 31. There are multiple limiting holes 13, and the guide 32 is provided on the limiting holes 13. The guide 32 is used to guide the installation of the clamping assembly 2. The fixing hole 14 is perpendicular to the first side slot 12 and is used to connect the limiting rod 34. The limiting rod 34 is connected to the wing bolt 31 and is used to limit the wing bolt 31 in the first side slot 12. The limiting rod 34 connects the first side slot 12 and the wing bolt 31.

[0063] like Figure 6 As shown, the clamping assembly 2 includes a clamping block 21, a clamping member 22, and a through groove 23. The clamping member 22 is connected to the clamping block 21 and cooperates with the placement groove 11 to restrict the position of the component 5 to be processed. The clamping block 21 is provided with a positioning hole 211, a threaded hole 212, and a second side slot 213. The guide member 32 cooperates with the positioning hole 211 to guide the clamping assembly 2 to connect with the base 1 along the guide member 32. The threaded hole 212 is used to connect the force application unit 4. The second side slot 213 is connected to the first side slot 12. The through groove 23 is on the clamping block 21 and passes through the clamping block 21 and the clamping member 22. When the clamping assembly 2 is connected with the base 1, the through groove 23 communicates with the placement groove 11. The geometric center of the through groove 23 is collinear with the geometric center of the placement groove 11. The positioning assembly 3 and the force application unit 4 can guide and position the component 5 to be processed and apply impact force through the through groove 23.

[0064] The wing bolt 31 is placed in the first side slot 12 and the second side slot 213, such as Figure 7 As shown, the wing bolt 31 includes a threaded rotating component 311, a retaining ring 312, and a nut rod 313. The nut rod 313 includes a threaded section 3131, a smooth section 3132, and a fixed section 3133. The threaded section 3131 is threadedly connected to the threaded rotating component 311. The retaining ring 312 is disposed between the threaded section 3131 and the smooth section 3132. The fixed section 3133 is a spherical structure with a through-hole in the middle. The limiting rod 34 is inserted into the cavity of the fixed section 3133 from the fixing hole 14 to fix the fixed section 3133 in the first side slot 12.

[0065] like Figure 8As shown, the wing bolt 31 can rotate around the limiting rod 34. When the clamping assembly 2 is not connected to the base 1, the wing bolt 31 can rotate from the first side slot 12 to both sides of the first side slot 12; when the clamping assembly 2 is connected to the base 1 along the guide member 32, the wing bolt 31 can rotate into the first side slot 12 and the second side slot 213, so that the fixing ring 312 is located on the top of the clamping block 21, as shown. Figure 2 As shown, tightening the threaded rotating component 311 and the fastening ring 312 presses the top of the clamping block 21 together, thereby fixing the connection between the clamping assembly 2 and the base 1.

[0066] like Figure 2 As shown, the positioning assembly 3 also includes a guide post 33 and a positioning screw 35. The guide post 33 is used to adjust the position of the element 5 in the placement slot 11 before connecting the force application unit 4. The positioning screw 35 is used to connect the force application unit 4 to the clamping assembly 2.

[0067] like Figure 9 As shown, the guide post 33 includes a post body 331, an inlet section 332, and a guide head 333. The post body 331 is connected to the inlet section 332, and the inlet section 332 is connected to the guide head 333. The guide post 33 can be inserted into the through groove 23, and the inlet section 332 can move within the through groove 23. The diameter of the guide head 333 matches the diameter of the machining hole 51, so that the guide head 333 is just inserted into the machining hole 51, thereby adjusting the position of the component 5 to be machined.

[0068] like Figure 10 As shown, the force-applying unit 4 includes a force-transmitting column 49, which includes a hammer head 491, a limiting rod 492, and a positioning head 493. The hammer head 491 is connected to the limiting rod 492, and the limiting rod 492 is connected to the positioning head 493. Figure 11 As shown, the limiting rod 492 is fixed to the through groove 23, so that the force transmission column 49 can only move up and down along the through groove 23, as... Figure 3 As shown, the positioning head 493 contacts the machining hole 51. The shape of the positioning head 493 matches the diameter of the deformed hole 52 after machining the machining hole 51. The force transmission column 49 is used to transmit the impact force to the component 5 and cause the machining hole 51 to deform in accordance with the positioning head 493, thereby machining the machining hole 51 into the deformed hole 52.

[0069] like Figures 12-13As shown, the force-applying unit 4 also includes a force-applying component 41, a housing 42, and a fixing component 43. The force-applying component 41 includes a rod 411, a push rod 412, a first spring 413, and a hammer body 414. The rod 411 passes through the top of the housing 42. The push rod 412 is connected to the rod 411. The rod 411 is connected to the hammer body 414. The first spring 413 is connected to the hammer body 414. A limiting pin 4141 is provided on the hammer body 414. There are multiple limiting pins 4141. A sliding groove 421 is provided on the housing 42. The sliding groove 421 cooperates with the limiting pins 4141, so that the limiting pins 4141 are in the sliding groove. The slide 421 slides within the groove 421, and a limiting groove 4211 is provided on the slide 421. When the limiting pin 4141 is placed in the limiting groove 4211, the position of the hammer body 414 can be fixed by the cooperation between the limiting pin 4141 and the limiting groove 4211, so as to prevent the hammer body 414 from interfering with the connection between the force application unit 4 and the clamping assembly 2. The fixing member 43 is provided on both sides of the bottom of the housing 42. The fixing member 43 is provided with a connecting hole 431, which cooperates with the threaded hole 212. The connecting hole 431 and the threaded hole 212 are connected by the positioning screw 35, so that the force application unit 4 is connected to the clamping assembly 2.

[0070] When an impact force needs to be applied to component 5, the position of component 5 in the placement groove 11 is adjusted by the guide post 33, the guide post 33 is pulled out, the force transmission post 49 is inserted into the through groove 23, the positioning head 493 contacts the machining hole 51, the force application unit 4 is connected to the clamping assembly 2 by the positioning screw 35, the limit pin 4141 is moved out of the limit groove 4211 by the push rod 412, and the push rod 412 is pulled upward to make the limit pin 4141 slide upward along the slide groove 421. At the very top of 421, the upper part of the first spring 413 is in a compressed state due to the restriction of the top of the outer shell 42, and stops applying force to the push rod 412. Under the action of gravity and the elastic force of the first spring 413, the hammer body 414 strikes the force transmission column 49 downward, so that the force transmission column 49 applies an impact force 0020 to the machining hole 51 through the positioning head 493. The hammer body 414 strikes the force transmission column 49 repeatedly in the above manner, thereby machining the machining hole 51 into the shape of the deformable hole 52.

[0071] Understandably, since the weight of the hammer body 414 is a fixed value, when the limiting pin 4141 slides upward along the slide groove 421 to the top of the slide groove 421, the deformation of the first spring 413 caused by the compression of the outer shell 42 is fixed. Therefore, during the application of impact force, the impact force generated by the hammer body 414 striking the force transmission column 49 downward each time is a fixed value, which realizes the uniform application of impact force and prevents the impact force from suddenly being too large or too small, thus damaging the structure of the component 5. The impact force is transmitted to the machining hole 51 through the force transmission column 49, and the deformation of the machining hole 51 is limited by the positioning head 493, thus realizing the control of the force transmission path and the amount of deformation.

[0072] Example 2

[0073] Another specific embodiment of the present invention, such as Figures 14-15 As shown, the difference from Embodiment 1 is that the force-applying unit 4 consists of a housing 42, a fixing member 43, a force transmission component 44, a spring component 45, a drive component 46, a hammer body 47, a hand crank 48, and a force transmission column 49. The hand crank 48 is connected to the drive component 46, and the drive force is provided to the drive component 46 by rotating the hand crank 48. The drive component 46 is connected to the force transmission component 44, and the force transmission component 44 is connected to the hammer body 47. The drive component 46 transmits the driving force to the hammer body 47 through the force transmission component 44, thereby causing the hammer body 47 to move up and down along the inner wall of the housing 42. The housing 42 does not have a sliding groove 421, but has a moving groove 422. The force transmission column 49 also includes a connecting rod 494, which is connected to the hammer head 491. The connecting rod 494 cooperates with the moving groove 422, allowing the force transmission column 49 to move up and down along the moving groove 422.

[0074] like Figure 15 As shown, the drive assembly 46 includes a fixed wheel 461, a connecting shaft 462, and a crank 463. The connecting shaft 462 passes through the housing 42 and is connected to the hand crank 48. The fixed wheel 461 and the crank 463 are mounted on the connecting shaft 462. The fixed wheel 461 is connected and fixed to the inner wall of the housing 42. When the hand crank 48 is turned, the connecting shaft 462 is rotated, thereby causing the crank 463 to rotate with the connecting shaft 462.

[0075] The force transmission assembly 44 includes a driven rod 441, a connecting member 442, and a force transmission rod 443. One end of the driven rod 441 is connected to the crank 463, and the other end is hinged to the connecting member 442. The connecting member 442 is connected to the force transmission rod 443. The spring assembly 45 includes a disc 451, a second spring 452, and a washer 453. The force transmission rod 443 is connected to the disc 451 and then to the hammer body 47. The disc 451 is in close contact with the inner wall of the outer shell 42. The disc 451 is connected to the second spring 452. The other end of the second spring 452 is connected to the washer 453. The washer 453 is fixed to the inner wall of the outer shell 42.

[0076] The hand crank 48 drives the crank 463 to rotate via the connecting shaft 462. The rotation of the crank 463 then drives the force transmission rod 443 and the hammer 47 to move up and down along the inner wall of the outer casing 42 via the driven rod 441. When the hand crank 48 drives the hammer 47 to move upward, the disc 451 moves upward with the force transmission rod 443, causing the second spring 452 to be stretched. When the hammer 47 moves to the highest point, the stretch of the second spring 452 is the maximum. Then, under its own weight and the elastic force of the second spring 452, the hammer 47 strikes the force transmission column 49 downward. The force transmission column 49 transmits the impact force of the hammer 47 to the component 5, providing the impact force required for the deformation of the machining hole 51. By repeatedly cranking the hand crank 48 to drive the hammer 47 to strike the force transmission column 49, the machining hole 51 is machined into the shape of the deformable hole 52.

[0077] When an impact force is applied to component 5, after adjusting the position of component 5 as described above, connect the force application unit 4 to the clamping assembly 2, so that the positioning head 493 of the force transmission column 49 contacts the machining hole 51. Connect the connecting hole 431 and the threaded hole 212 through the positioning screw 35, thereby connecting the force application unit 4 to the clamping assembly 2. At this time, the connecting rod 494 is located at the top of the moving groove 422. The hammer 47 strikes the force transmission column 49 as described above. As the force transmission column 49 is struck and presses downward into the machining hole 51, the connecting rod 491 moves downward along the moving groove 422. The force transmission column 49 transmits the impact force of the hammer 47 to component 5. The impact and compression of the positioning head 493 causes the machining hole 51 to deform in conjunction with the positioning head 493.

[0078] Preferably, a vernier and a scale are provided on the moving groove 422. The displacement of the connecting rod 494 along the moving groove during the hammering process can be measured by the vernier and the scale, thereby predicting the deformation of the machined hole 51.

[0079] It is understood that the impact deformation processing device provided in this embodiment provides impact force by controlling the lifting and lowering of the hammer 47 through the hand crank 48. The operation is simple, providing convenience for technicians in actual operation and easy control. The weight of the hammer 47 is a fixed value. When the hammer 47 moves to the highest point, the extension of the second spring 452 is a fixed value. Therefore, during the application of impact force, the impact force generated by the hammer 47 hitting the force transmission column 49 downward each time is a fixed value, realizing the uniform application of impact force and preventing the impact force from suddenly being too large or too small, thus damaging the structure of component 5. The impact force is transmitted to the processing hole 51 through the force transmission column 49, and the deformation of the processing hole 51 is controlled by the positioning head 493. During the process of applying impact force to deform the processing hole 51, the force transmission path and deformation are controlled. When the processing state of the processing hole 51 cannot be seen, the impact of the positioning head 493 on the processing hole 51 can be intuitively reflected by setting a vernier and a scale, thereby predicting the deformation of the processing hole 51 caused by the impact force.

[0080] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
