Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a cabin machining clamping device. Background Technology

[0002] The aircraft hull is a key component of an aircraft, playing a vital role in protecting the aircraft's internal structure and enabling the aircraft's designed functions.

[0003] The basic structural form of the cabin workpiece is "end frame + skin + end frame". The main body is a skin structure, and the two ends are end frames. The inner and outer circles of the end frames are regular circles. Mounting holes are arranged on the end face of the end frame. In addition, several windows are usually opened on the skin of this type of cabin.

[0004] In the prior art, due to the different shapes of the cabin skin structure and the relatively thin wall thickness, the cabin skin is easily deformed and indented when using existing fixtures for clamping, making it difficult to clamp the cabin workpiece during machining. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide a cabin machining clamping device to solve the problems of poor workpiece alignment and clamping quality in the prior art.

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

[0007] This invention discloses a cabin machining clamping device for aligning and clamping cabin workpieces. It includes a chassis assembly, a pressure plate, a tensioning assembly, and a clamping assembly. The cabin workpiece is disposed between the chassis assembly and the pressure plate.

[0013] Furthermore, the pressure bar is configured as a telescopic rod structure.

[0014] Furthermore, the positioning pin is configured as a stepped pin that is interference-fitted with the chassis.

[0015] Furthermore, a baffle is provided on the chassis to fix the position of the cabin workpiece.

[0016] Furthermore, the press is provided with an arc-shaped protrusion for fixing the position of the small-diameter end frame of the cabin workpiece.

[0017] Furthermore, the chassis assembly also includes an arc-shaped positioning block and a baffle adjusting component.

A first arc groove is provided on the first gear plate, and the baffle is connected to the first gear plate through the first arc groove.

[0018] Furthermore, a first connecting block and a first moving head are provided on the baffle. The baffle is connected to the first moving head through the first connecting block. The first moving head is located in the first arc groove. When the first drive gear drives the first gear disk to rotate, the first moving head moves along the first arc groove with the rotation of the first drive gear.

[0019] Furthermore, the pressure plate is also provided with a convex adjustment component for adjusting the arc-shaped convex. The convex adjustment component includes a second gear and a second drive gear. Both the second gear and the second drive gear are connected to the pressure plate through bearing seats. The second gear is provided with a second arc groove. The arc-shaped convex is provided with a second connecting block and a second moving head. The arc-shaped convex is connected to the second moving head through the second connecting block. The second moving head is located in the second arc groove and can move along the second arc groove as the second drive gear rotates.

[0020] Furthermore, it also includes a clamping prompting unit, which includes a prompting element, a measuring ball, a connecting plate, a support plate, a compression spring, and a housing. The connecting plate, the support plate, and the compression spring are all housed inside the housing, which is mounted on the chassis. The support plate is connected to the housing, and the middle part of the connecting plate is hinged to the support plate. One end of the connecting plate is connected to the prompting element, and the other end is connected to the measuring ball. The end of the connecting plate connected to the measuring ball is connected to the chassis via the compression spring.

[0021] Furthermore, a ball hole is provided on the chassis, and the ball hole is positioned to match the position of the measuring ball. The measuring ball protrudes from the ball hole under the action of a compression spring. A column hole is provided at the baffle of the chassis, and the position of the column hole is matched with the indicator, so that the indicator can protrude from the column hole.

[0022] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0023] (1) The cabin machining clamping device provided by the present invention can position and clamp cabin workpieces by setting a chassis assembly, a pressure plate, a tensioning assembly, and a clamping assembly. The cabin workpiece is quickly positioned by the arc-shaped protrusion on the pressure plate and the arc-shaped positioning block and positioning pin on the chassis. The tensioning assembly makes the pressure plate and the chassis cooperate to secure the position of the cabin workpiece. The clamping assembly fixes the position of the window on the cabin workpiece, thereby realizing the clamping of the cabin workpiece. The cabin machining clamping device can also process the inner cavity of the cabin workpiece by using the arc-shaped positioning block and the clamping assembly. The small-diameter end frame of the cabin workpiece is fitted onto the arc-shaped positioning block, and the arc-shaped positioning block is pressed against the inner wall of the small-diameter end frame. The clamping assembly is adjusted to fix the position of the window by the clamping plate, thereby connecting the small-diameter end frame of the cabin workpiece to the chassis assembly, which facilitates the processing of the inner cavity of the cabin workpiece. The aforementioned cabin machining clamping device is convenient to use for machining cabin workpieces, has a simple structure, is easy to operate, and can avoid damage to the skin, thus improving the safety and stability of clamping cabin workpieces.

[0024] (2) The cabin machining clamping device provided by the present invention, by setting a baffle adjustment component on the chassis assembly and a protrusion adjustment component on the pressure plate, can adjust the position of the baffle and the arc-shaped protrusion according to the diameter of the end frame of the cabin workpiece, so that the cabin machining clamping device can clamp and position cabin workpieces with different end frame diameters. A first arc groove is set on the first gear plate, and the baffle is connected to the first gear plate through the first arc groove. The rotation of the first gear plate can cause the baffle to shrink outward or expand inward, so that the baffle is in close contact with the inner wall of the large-diameter end frame of the cabin workpiece; the second moving head is set in the second arc groove. The second moving head can move along the second arc groove with the rotation of the second drive gear, and the arc-shaped protrusion is displaced through the second connecting block, so that the ring formed by the arc-shaped protrusion increases or decreases, so that the arc-shaped protrusion is in close contact with the inner wall of the small-diameter end frame of different cabin workpieces, so that the cabin machining clamping device can adjust different cabin workpieces. The clutch connects the first and second shafts. When the tilt of the workpiece remains constant, the positions of the baffle and the arc-shaped protrusion can be adjusted synchronously via the handle, thereby accelerating the fixing and alignment of the workpiece and achieving rapid positioning. When fixing workpieces with different tilt angles, controlling the clutch allows for individual adjustment of the baffle and the arc-shaped protrusion to align and fix the workpiece. The operation is simple, highly adaptable to workpieces, and enables rapid alignment and fixing, saving operation time and improving processing efficiency.

[0025] (3) The cabin machining clamping device provided by the present invention is further provided with a clamping reminder unit to prevent the tensioning assembly and pressure plate from excessively squeezing the cabin workpiece, causing the skin to be deformed by pressure, and to display the clamping status of the cabin workpiece. When clamping the cabin workpiece, the pressure plate is pressed and fixed to the position of the cabin workpiece by tightening the set nut. The large-diameter end frame of the cabin workpiece squeezes the measuring ball, causing the measuring ball to move into the ball hole, squeezing the compression spring, and raising the other end of the connecting plate, so that the reminder protrudes from the column hole, reminding the technician to prevent excessive clamping from causing skin deformation. When testing the clamping status of the cabin workpiece, the cabin workpiece is tilted at a certain angle. If the cabin workpiece is not fixed securely, a gap appears between the large-diameter end frame of the cabin workpiece and the chassis during the tilting process. The measuring ball at the gap protrudes from the ball hole under the action of the compression spring, causing the end of the connecting plate connected to the reminder to descend, so that the indicator enters the column hole, reminding the technician to readjust the set nut. By setting a clamping reminder unit, technicians can be prompted to avoid over-tightening the set nut, preventing excessive pressure on the pressure plate that could cause skin deformation. Simultaneously, the clamping reminder unit can display the clamping status of the workpiece, facilitating its inspection and allowing for timely adjustment of the clamping degree. This improves the safety and stability of the workpiece machining clamping device, enhances the efficiency of workpiece clamping status inspection, and facilitates monitoring of the clamping status.

[0026] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention.

Detailed Implementation

[0040] 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.

The clamping assembly 4 is disposed on the chassis assembly 1 and is used to fix the connection between the cabin workpiece 5 and the chassis assembly 1.

[0043] The tensioning assembly 3 includes a set rod 31 and a set nut 32. The set rod 31 is connected to the chassis assembly 1. The pressure plate 2 is provided with a set hole. The set nut 32 passes through the set hole and is threadedly connected to the set rod 31, thereby pressing the pressure plate 2 to press the cabin workpiece 5, improving the stability of the cabin processing clamping device in fixing the cabin workpiece 5.

[0044] The chassis assembly 1 includes a chassis 11 and a locating pin 12. The locating pin 12 is disposed on the chassis 11 and is used for machining reference positioning.

[0045] Preferably, the positioning pin 12 is configured as a stepped pin that is interference-fitted with the chassis 11.

[0046] Furthermore, such as Figures 2-3As shown, the clamping assembly 4 includes a clamping plate 41, a clamping rod 42, and a clamping nut 43. One end of the clamping rod 42 is connected to the chassis 11, and the other end is connected to the clamping plate 41 via the clamping nut 43. The position of the clamping plate 41 matches the position of the window 51 of the cabin workpiece 5, as shown. Figure 1 and Figure 3 As shown, the window 51 is fixed by the clamping plate 41, thereby fixing the connection between the cabin workpiece 5 and the chassis 11.

[0047] Preferred, such as Figure 3 As shown, a movable groove 411 is provided on the pressing plate 41, and a pressure rod 42 is provided in the movable groove 411. The movable groove 411 can move along the pressure rod 42, and the movement of the pressing plate 41 is fixed by tightening the pressing nut 43, so that the pressing plate 41 can be adjusted according to the position of the window 51.

[0048] Preferably, the pressure rod 42 is configured as a telescopic rod structure, so that the height of the pressure rod 42 can be adjusted according to the position of the window 51, and the pressure rod 42 can be retracted when processing the inner cavity of the cabin workpiece 5 to avoid interfering with the processing.

[0049] Furthermore, a baffle 111 is provided on the chassis 11, and the large-diameter end frame of the cabin workpiece 5 can be closely attached to the inner wall of the baffle 111, thereby positioning the cabin workpiece 5.

[0050] Furthermore, such as Figure 4 As shown, an arc-shaped protrusion 21 is provided on the pressure plate 2. The arc-shaped protrusion 21 is in close contact with the inner wall of the small diameter end frame of the cabin workpiece 5, thereby positioning the cabin workpiece 5.

[0051] Furthermore, such as Figure 2 As shown, the chassis assembly 1 also includes an arc-shaped positioning block 13, which is disposed on the chassis 11. The arc-shaped positioning block 13 is used to position the small-diameter end frame of the cabin workpiece 5. The arc-shaped positioning block 13 is in close contact with the inner wall of the small-diameter end frame of the cabin workpiece 5. The tensioning assembly 3 and the pressing assembly 4 are disposed on the arc-shaped positioning block 13.

[0052] When it is necessary to process the inner cavity of the cabin workpiece 5, the small diameter end frame of the cabin workpiece 5 is placed on the arc-shaped positioning block 13, and the arc-shaped positioning block 13 is tightly attached to the inner wall of the small diameter end frame. The clamping assembly 4 is adjusted so that the clamping plate 41 fixes the position of the window 51, thereby connecting the small diameter end frame of the cabin workpiece 5 with the chassis assembly 1, which facilitates the processing of the inner cavity of the cabin workpiece 5.

[0053] Example 2

[0054] This embodiment provides a cabin machining clamping device, such as... Figures 5-6As shown, the difference from Embodiment 1 is that the chassis assembly 1 also includes a baffle adjustment component 14 for adjusting the baffle 111; the pressure plate 2 is also provided with a protrusion adjustment component 22 for adjusting the arc-shaped protrusion 21, so that the cabin processing clamping device can clamp and position cabin workpieces 5 with different end frame diameters.

[0055] like Figure 5 As shown, multiple baffles 111 are provided, and the multiple baffles 111 can form a ring structure. The baffle adjusting component 14 is provided in the arc-shaped positioning block 13. The baffle adjusting component 14 includes a first gear disk 141 and a first drive gear 142. The first gear disk 141 and the first drive gear 142 are both connected to the arc-shaped positioning block 13 through bearing seats. The first drive gear 142 meshes with the first gear disk 141. The first gear disk 141 can rotate with the rotation of the first drive gear 142. A first arc groove 1411 is provided on the first gear disk 141. The baffle 111 is connected to the first gear disk 141 through the first arc groove 1411. The rotation of the first gear disk 141 can cause the baffle 111 to contract outward or expand inward, so that the baffle 111 is tightly attached to the inner wall of the large-diameter end frame of the cabin workpiece 5.

[0056] A first connecting block 1111 and a first moving head 1112 are provided on the baffle 111. The baffle 111 is connected to the first moving head 1112 through the first connecting block 1111. The first moving head 1112 is located in the first arc groove 1411. When the first drive gear 142 drives the first gear disk 141 to rotate, the first moving head 1112 moves along the first arc groove 1411 with the rotation of the first drive gear 142. The first connecting block 1111 causes the baffle 111 to be displaced, so that the ring formed by the baffle 111 increases or decreases, thereby enabling the baffle 111 to fit tightly against the inner wall of the large-diameter end frame of the different cabin workpieces 5.

[0057] Preferably, a slider is provided on the baffle 111 and a slide rail is provided on the chassis 11, so that the baffle 111 and the chassis 11 are connected by the slider and the slide rail, so that the baffle 111 can move along the slide rail, thereby increasing the stability of the movement of the baffle 111.

[0058] like Figure 6As shown, the pressure plate 2 is provided with multiple arc-shaped protrusions 21, which can form a ring structure. The arc-shaped protrusions 21 are connected to the protrusion adjusting member 22. The protrusion adjusting member 22 includes a second gear 221 and a second drive gear 222. Both the second gear 221 and the second drive gear 222 are connected to the pressure plate 2 through bearing seats. The second gear 221 is provided with a second arc groove 2211, and the arc-shaped protrusion 21 is provided with a second connecting block 211 and a second moving head 212. The arc-shaped protrusion 21 is connected to the second moving head 212 through the second connecting block 211. The second moving head 212 is located in the second arc groove 2211. The second moving head 212 can move along the second arc groove 2211 with the rotation of the second drive gear 222. The second moving head 212 can cause the arc-shaped protrusion 21 to be displaced through the second connecting block 211, so that the ring formed by the arc-shaped protrusion 21 can be enlarged or reduced, thereby enabling the arc-shaped protrusion 21 to be in close contact with the inner wall of the small diameter end frame of the different cabin workpieces 5.

[0059] Preferably, a slider is provided on the arc-shaped protrusion 21 and a slide rail is provided on the pressure plate 2, so that the arc-shaped protrusion 21 and the pressure plate 2 are connected by the slider and the slide rail, so that the arc-shaped protrusion 21 can move along the slide rail, thereby increasing the stability of the movement of the arc-shaped protrusion 21.

[0060] Furthermore, the convex adjustment component 22 also includes a second shaft 223, which is connected to a second drive gear 222, and the second drive gear 222 can drive the second shaft 223 to rotate. A handle is provided on the second shaft 223, and the second shaft 223 passes through the pressure plate 2 and is connected to the handle.

[0061] Furthermore, the baffle adjusting component 14 also includes a first shaft 143, which is connected to a first drive gear 142. Rotating the first shaft 143 can drive the first drive gear 142 to rotate. Figure 7 As shown, an adjustment groove 112 is provided on the chassis 11, and a rotating wheel is provided in the adjustment groove 112. The rotating wheel is connected to the first shaft 143 and is used to rotate the first drive gear 142.

[0062] It is worth noting that the height of the rotating wheel is less than the bottom surface of the chassis 11 to avoid affecting the flatness of the chassis 11.

[0063] Preferably, the first shaft 143 and the second shaft 223 are connected by a clutch. Turning the handle can drive the second shaft 223 to rotate together with the first shaft 143, thereby synchronously adjusting the positions of the baffle 111 and the arc-shaped protrusion 21. When the inclination of the cabin workpiece 5 remains unchanged, synchronously adjusting the positions of the baffle 111 and the arc-shaped protrusion 21 by the handle can speed up the alignment of the cabin workpiece 5 and achieve rapid positioning. When fixing cabin workpieces 5 with different inclinations, controlling the clutch prevents the first shaft 143 from rotating with the second shaft 223, thereby adjusting the positions of the baffle 111 and the arc-shaped protrusion 21 respectively, and aligning and fixing the cabin workpiece 5.

[0064] Preferably, the clutch control switch is located on the handle, which facilitates the control of the clutch status.

[0065] Preferred, such as Figure 8 As shown, the chassis assembly 1 also includes a washer 15, which is connected to the chassis 11. The washer 15 is arranged around the arc-shaped positioning block 13. When the arc-shaped positioning block 13 is used to position the small-diameter end frame of the cabin workpiece 5, the cabin workpiece 5 can be placed on the washer 15 for positioning, thereby enabling the inner cavity of the cabin workpiece 5 to be processed.

[0066] Example 3

[0067] This embodiment provides a cabin machining clamping device, such as... Figure 9 As shown, the difference from Embodiment 1 or Embodiment 2 is that it also includes a clamping indication unit 6, which is used to prevent the tensioning assembly 3 and the pressure plate 2 from excessively squeezing the cabin workpiece 5, causing the skin to be deformed by pressure, and to indicate the clamping status of the cabin workpiece 5.

[0068] like Figures 9-10 As shown, the clamping prompting unit 6 includes a prompting element 61, a measuring ball 62, a connecting plate 63, a support plate 64, a compression spring 65, and a housing 66. The connecting plate 63, the support plate 64, and the compression spring 65 are disposed inside the housing 66, which is disposed on the chassis 11 and is coplanar with the chassis 11. The support plate 64 is connected to the housing 66. The middle part of the connecting plate 63 is hinged to the support plate 64. One end of the connecting plate 63 is connected to the indicator 61, and the other end is connected to the measuring ball 62. The end of the connecting plate 63 connected to the measuring ball 62 is connected to the housing 66 through a compression spring 65. A ball hole is provided on the housing 66, and the ball hole is matched with the position of the measuring ball 62. The measuring ball 62 protrudes from the ball hole under the action of the compression spring 65. When the cabin workpiece 5 contacts the chassis 11, it can squeeze the measuring ball 62 to compress the compression spring 65. A column hole is also provided on the housing 66, and the position of the column hole is matched with the indicator 61, so that the indicator 61 can protrude from the column hole.

[0069] Preferably, the clamping indicator units 6 are configured as multiple units and distributed along the circumference of the chassis 11, thereby increasing the accuracy of the clamping indicator units 6 in indicating the clamping status of the workpiece 5 in the cabin.

[0070] Preferably, a sliding groove is provided on the chassis 11, and the housing 66 is disposed in the sliding groove. The housing 66 can move along the sliding groove, so that the position of the clamping indicator unit 6 can be adjusted according to the position of the baffle 111.

[0071] When clamping the cabin workpiece 5, tightening the set nut 32 causes the pressure plate 2 to press and fix the position of the cabin workpiece 5. The large-diameter end frame of the cabin workpiece 5 presses the measuring ball 62, causing the measuring ball 62 to move into the ball hole, compressing the compression spring 65, and raising the other end of the connecting plate 63, thereby causing the indicator 61 to protrude from the column hole, reminding the technicians to prevent excessive tightening from causing skin deformation.

[0072] When testing the clamping state of the test chamber workpiece, the test chamber workpiece 5 is tilted at a certain angle. If the fixation of the test chamber workpiece 5 is not stable, a gap will appear between the large-diameter end frame of the test chamber workpiece 5 and the chassis 11 during the tilting process. The measuring ball 62 at the gap will bulge out of the ball hole under the action of the compression spring 65, causing the end of the connecting plate 63 connected to the indicator 61 to descend, so that the indicator 61 enters the column hole, reminding the technician that the set nut 32 needs to be readjusted.

[0073] By setting the clamping reminder unit 6, technicians can be prompted to avoid over-tightening the set nut 32 when adjusting it, thus preventing the pressure plate 2 from being over-pressurized and causing skin deformation. At the same time, the clamping reminder unit 6 can also display the clamping status of the cabin workpiece 5, which is convenient for checking the clamping status of the cabin workpiece 5, thereby adjusting the clamping degree of the cabin workpiece 5 in a timely manner, improving the safety and stability of the cabin processing clamping device, facilitating the detection of the clamping status of the cabin workpiece, and improving the efficiency of checking the clamping status of the cabin workpiece.

[0074] 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.

When clamping the workpiece, the pressure plate presses and fixes the position of the workpiece. The large-diameter end frame of the workpiece squeezes the measuring ball, causing the measuring ball to move into the ball hole, compressing the compression spring and raising the other end of the connecting plate, thus causing the indicator to protrude from the column hole. When testing the clamping state of the workpiece, the workpiece is tilted at a certain angle. If the workpiece is not securely fixed, a gap will appear between the large-diameter end frame of the workpiece and the chassis during the tilting process. The measuring ball at the gap will protrude from the ball hole under the action of the compression spring, causing the end of the connecting plate connected to the indicator to descend, allowing the indicator to enter the column hole.
