The second pressure detection part 150 is arranged on the drilling simulation device 140, and the pressure value applied by the drilling simulation device 140 to the partition is detected by the second pressure detection part 150.

The position of the drilling simulation device 140 relative to the workpiece 200 is adjusted by the adjusting part 160. After the adjusting part 160 adjusts the drilling simulation device 140 to abut against the partition, the adjusting part 160 adjusts the drilling simulation device 140 to press against the partition to apply a simulated drilling force to the workpiece 200, so that the simulated drilling force applied by the drilling simulation device 140 to the workpiece 200 reaches a preset drilling force value by obtaining the simulated drilling force value detected by the second pressure detection part 150, to complete the simulation of clamping and drilling of the workpiece 200. The actual clamping deformation amount and the actual drilling deformation amount of the workpiece 200 are detected by the deformation amount detection part, so that the relationship between the clamping force and the clamping deformation amount and the relationship between the drilling force and the drilling deformation amount are obtained, to lay a foundation for controlling the deformation of the thin-walled part with a partition.

[0068] It can be understood that the support part 110 is provided with a base 111, a support column 112 and a flange plate 113. Among them, the support column 112 is arranged on the top of the base 111, and the support column 112 can be provided with a plurality of support columns 112 arranged in a ring array, and each support column 112 can be fixedly connected to the base by screws. The flange plate 113 is arranged on the support column 112, and specifically, the top of each support column 112 is provided with a protrusion, and a plurality of protrusions are arranged in a ring array. The bottom of the flange plate 113 is provided with a ring groove, and the protrusion is inserted into the ring groove. The clamping part 120 is supported by the flange plate 113.

[0069] Exemplarily, the support column 112 is provided with four support columns 112 arranged in a ring array, and the included angle between adjacent support columns 112 is 90°.

[0070] In some examples, as shown in Figure 1 and Figure 2 The clamping part 120 includes a chuck 121 arranged at one end of the flange plate 113 away from the support column 112, and a jaw 122 arranged on the chuck 121, the jaw 122 is used to press on the inner diameter of the clamping end of the workpiece 200 to tighten the workpiece 200, and the adjusting part 160 is used to adjust the position of the jaw 122 relative to the workpiece 200. The first pressure detection part 130 is arranged on the outside of the clamping side of the jaw 122, and the outer contour of the first pressure detection part 130 and the inner contour of the clamping end of the workpiece 200 are fitted.

[0071] It can be understood that the clamping part 120 can be provided with a chuck 121 and a jaw 122. Among them, the chuck 121 is arranged at one end of the flange plate 113 away from the support column 112, the jaw 122 is arranged on the chuck 121, the adjusting part 160 can adjust the radial movement of the jaw 122 along the chuck 121, so as to adjust the position of the jaw 122 relative to the workpiece 200. When the adjusting part 160 adjusts the outer side of the jaw 122 to press on the inner diameter of the clamping end of the workpiece 200, the workpiece 200 is tightened and fixed by the jaw 122. And the first pressure detection part 130 is arranged at one end of the jaw 122 towards the workpiece 200, the jaw 122 drives the first pressure detection part 130 to press on the inner diameter of the clamping end of the workpiece 200, so as to detect the actual clamping force value by the first pressure detection part 130, and the clamping part 120 completes the clamping of the workpiece 200 when the actual clamping force value reaches the preset clamping force value. In order to ensure the clamping effect and the detection effect of the first pressure detection part 130, the outer contour of the first pressure detection part 130 and the inner contour of the clamping end of the workpiece 200 are fitted.

[0072] In some examples, as shown in Figure 1 and Figure 2As shown, the adjusting part 160 comprises a driving member 161, a first adjusting member 162 connected to the chuck 121 for adjusting the opening size of the clamping jaw 122, a second adjusting member 163 arranged in a placement space formed by the base 111, the support column 112 and the flange plate 113 for adjusting the movement of the drilling simulation device 140 towards or away from the partition plate, and a switching member 164 for switching the first adjusting member 162 to be connected to the driving member 161 or switching the second adjusting member 163 to be connected to the driving member 161.

[0073] It can be understood that the adjusting part 160 can be provided with the driving member 161, the first adjusting member 162, the second adjusting member 163 and the switching member 164. The first adjusting member 162 is connected to the chuck 121 to adjust the opening size of the clamping jaw 122 through the first adjusting member 162. The second adjusting member 163 is arranged in the placement space formed by the base 111, the support column 112 and the flange plate 113 to adjust the movement of the drilling simulation device 140 towards or away from the partition plate through the second adjusting member 163. The switching member 164 switches the first adjusting member 162 to be connected to the driving member 161 or switches the second adjusting member 163 to be connected to the driving member 161. In this way, when the clamping operation of the workpiece 200 is performed, the switching member 164 switches the first adjusting member 162 to be connected to the driving member 161, and the driving member 161 drives the first adjusting member 162 to move the clamping jaw 122, so that the actual clamping force applied to the workpiece 200 by the clamping part 120 reaches the preset clamping force. When the drilling simulation operation is performed, the switching member 164 switches the second adjusting member 163 to be connected to the driving member 161, and the driving member 161 drives the second adjusting member 163 to move the drilling simulation device 140 towards the partition plate, so that the drilling simulation device 140 presses the partition plate until the simulation drilling force value applied to the workpiece 200 by the drilling simulation device 140 reaches the preset drilling force value. In this way, the simulation clamping and drilling of the workpiece 200 are completed, and the clamping deformation and the drilling deformation of the workpiece 200 are detected by the deformation detection part, so that the relationship between the clamping force and the clamping deformation and the relationship between the drilling force and the drilling deformation are obtained, which lays a foundation for controlling the deformation of the thin-walled part of the partitioned rotary body. The switching member 164 is arranged to avoid the mutual interference of the first adjusting member 162 and the second adjusting member 163 during adjustment, which affects the adjustment effect and improves the reliability.

[0074] In some examples, as Figure 1 and Figure 2As shown, the first adjusting member 162 comprises: a shaft shoulder screw, a first bevel gear arranged along the radial direction of the chuck 121, the shaft shoulder screw being connected to the first bevel gear; a second bevel gear arranged along the axial direction of the chuck 121, the second bevel gear being engaged with the first bevel gear towards one end of the flange plate 113, and the second bevel gear being provided with a flat thread away from one end of the flange plate 113, the bottom end of the claw 122 being provided with a rack, the rack being engaged with the flat thread; wherein, when the shaft shoulder screw is connected to the driving member 161 by the switching member 164, the driving member 161 drives the shaft shoulder screw to rotate, and the shaft shoulder screw drives the first bevel gear to rotate.

[0075] It can be understood that the first adjusting member 162 is provided with a shaft shoulder screw, a first bevel gear and a second bevel gear. The first bevel gear is arranged along the radial direction of the chuck 121, and the chuck 121 is provided with a clamping groove in the radial direction, the shaft shoulder screw is inserted into the clamping groove and connected to the first bevel gear, and the shaft shoulder screw can rotate synchronously with the first bevel gear.

In this way, when the workpiece 200 needs to be clamped, the switching member 164 is switched to connect the shaft shoulder screw to the driving member 161, the driving member 161 drives the shaft shoulder screw to rotate, the shaft shoulder screw drives the first bevel gear to rotate synchronously, thereby driving the second bevel gear to rotate along the axial direction of the chuck 121, the flat thread of the second bevel gear rotates, thereby driving the rack to move towards the inner diameter direction of the clamping end of the workpiece 200, so as to press the inner diameter of the clamping end of the workpiece 200 with the claw 122, and clamp the workpiece 200. When the workpiece 200 needs to be disassembled, the shaft shoulder screw can be driven to rotate in the opposite direction by the driving member 161.

[0076] It can be understood that the chuck 121 and the flange plate 113 can be fixedly connected by bolts.

[0077] In some examples, as Figure 1 and Figure 2As shown, the second adjusting member 163 includes a housing 1631 arranged in the placement space, a worm 1632 arranged in the housing 1631, and a driving end of the worm 1632 extending out of the housing 1631 and located outside the support column 112 for being connected to the driving member 161, a worm nut 1633 arranged in the housing 1631, an outer circle of the worm nut 1633 being a worm mechanism, the worm mechanism being engaged with the worm 1632, and a central through hole of the worm nut 1633 being an internal thread mechanism, and a rod body 1634, a screw structure being arranged at a bottom end of the rod body 1634, the screw structure being engaged with the internal thread mechanism, the rod body 1634 being arranged through the support part 110 and the clamping part 120, and a top end of the rod body 1634 being threadedly connected with the drilling simulation device 140.

[0078] It can be understood that the second adjusting member 163 is provided with the housing 1631, the worm 1632, the worm nut 1633 and the rod body 1634. The housing 1631 is arranged in the placement space, the worm 1632 is arranged in the housing 1631, and a driving end of the worm 1632 extends out of the housing 1631 and is located outside the support column 112, the driving end of the worm 1632 being connected to the driving member 161. The worm nut 1633 is arranged in the housing 1631, an outer circle of the worm nut 1633 being a worm mechanism, the worm mechanism being engaged with the worm 1632, a central through hole of the worm nut 1633 being an internal thread mechanism, and a central axis of the worm nut 1633 coinciding with an axis of the chuck 121. A screw structure is arranged at a bottom end of the rod body 1634, the screw structure being engaged with the internal thread mechanism, the rod body 1634 being arranged through the support part 110 and the clamping part 120, and a top end of the rod body 1634 being threadedly connected with the drilling simulation device 140. In this way, when the simulation drilling is performed, the switching member 164 is switched to the worm 1632 being connected to the driving member 161, the driving member 161 drives the worm 1632 to rotate, the worm 1632 drives the worm nut 1633 to rotate, thereby driving the screw to move linearly, so that the rod body 1634 drives the drilling simulation device 140 to move towards the workpiece 200, the drilling simulation device 140 presses the drilling position, until the simulation drilling force applied to the partition plate reaches the preset drilling force value. When it is needed to stop the simulation drilling, the driving member 161 drives the worm 1632 to rotate reversely.

[0079] Exemplarily, a through hole is arranged at a central position of the base 111, the screw structure of the rod body 1634 can be inserted into the through hole, and bearings 1635 are arranged at two ends of the worm nut 1633.

[0080] In some examples, as Figure 1 and Figure 2As shown, the center axis of the rod body 1634, the center axis of the worm nut 1633 and the center axis of the workpiece 200 coincide when the workpiece 200 is clamped in place.

[0081] It can be understood that the center axis of the rod body 1634, the center axis of the worm nut 1633 and the center axis of the workpiece 200 coincide to improve stability and balance the force.

[0082] In some examples, as shown, Figure 1 As shown, the switching member 164 includes a first gear 1641 sleeved on the output shaft of the driving member 161, the first gear 1641 being used to rotate synchronously with the output shaft; a second gear 1642 sleeved on the shaft shoulder screw, the second gear 1642 being engaged with the first gear 1641; a third gear 1643 sleeved on the part of the worm 1632 extending from the support column 112, the third gear 1643 being engaged with the first gear 1641; a first electromagnetic clutch 1644 arranged between the shaft shoulder screw and the second gear 1642, the first electromagnetic clutch 1644 being connected when energized, the shaft shoulder screw and the second gear 1642 rotating synchronously; the first electromagnetic clutch 1644 being separated when de-energized, the shaft shoulder screw and the second gear 1642 being clearance fitted; a second electromagnetic clutch 1645 arranged between the worm 1632 and the third gear 1643, the second electromagnetic clutch 1645 being connected when energized, the worm 1632 and the third gear 1643 rotating synchronously; the second electromagnetic clutch 1645 being separated when de-energized, the worm 1632 and the third gear 1643 being clearance fitted.

[0083] It can be understood that the switching piece 164 is provided with a first gear 1641, a second gear 1642, a third gear 1643, a first electromagnetic clutch 1644 and a second electromagnetic clutch 1645. Among them, the first gear 1641 is sleeved on the output shaft of the driving piece 161, and the output shaft of the driving piece 161 can drive the first gear 1641 to rotate synchronously. The second gear 1642 is sleeved on the shaft shoulder screw, and the second gear 1642 is in clearance fit with the shaft shoulder screw. The third gear 1643 is sleeved on the driving end of the worm 1632, and the third gear 1643 and the worm 1632 are in clearance fit. The first electromagnetic clutch 1644 is arranged between the shaft shoulder screw and the second gear 1642. When the first electromagnetic clutch 1644 is in the connected state, the shaft shoulder screw and the second gear 1642 rotate synchronously; when the first electromagnetic clutch 1644 is in the disconnected state, the shaft shoulder screw and the second gear 1642 are in clearance fit. The second electromagnetic clutch 1645 is arranged between the worm 1632 and the third gear 1643, and when the second electromagnetic clutch 1645 is in the connected state, the worm 1632 and the third gear 1643 rotate synchronously; when the second electromagnetic clutch 1645 is in the disconnected state, the worm 1632 and the third gear 1643 are in clearance fit. In this way, when the simulation clamping operation is performed, the first electromagnetic clutch 1644 is controlled to be connected, and the second electromagnetic clutch 1645 is controlled to be disconnected, so that the driving piece 161 drives the shaft shoulder screw to rotate, so as to adjust the distance between the clamping jaw 122 and the workpiece 200 and the clamping force applied to the workpiece 200; when the simulation drilling operation is performed, the second electromagnetic clutch 1645 is controlled to be connected, and the first electromagnetic clutch 1644 is controlled to be disconnected, so that the driving piece 161 drives the worm 1632 to rotate, so as to adjust the distance between the drilling simulation device 140 and the workpiece 200 and the simulation cutting force applied to the workpiece 200. In this way, the first adjusting piece 162 and the second adjusting piece 163 are avoided from interfering with each other when adjusting, the adjusting effect is affected, and the reliability is improved.

[0084] Exemplarily, as shown in Figure 2 , the first electromagnetic clutch 1644 and the second electromagnetic clutch 1645 can each be selected as an electromagnetic spline 1646. The spline groove of the electromagnetic spline 1646 is N level, the electromagnetic spline 1646 is S when electrified, that is, the spline is attracted to the spline groove, the spline is stretched out and in clearance fit with the spline groove; the electromagnetic spline 1646 is N when de-energized, the spline groove is repelled by the spline, and the spline is retracted.

[0085] In some examples, as Figures 1 to 3 Figure 3 Figure 4As shown, the drilling simulation device 140 includes a cover 141, a top end of the rod body 1634 is threadedly connected with the cover 141, a sleeve 142 abuts against one end of the cover 141 towards the claw 122, a tapered threaded hole is formed in a middle portion of the sleeve 142, a tip of the tapered threaded hole is away from the cover 141, a tapered gear ring 143 is screwed in the tapered threaded hole, the second pressure detection portion 150 is arranged at one end of the tapered gear ring 143 towards the claw 122, a fourth gear 144 is sleeved on the sleeve 142, the fourth gear 144 is provided with a mounting hole in an axial direction of the rod body 1634, a motor 145 is arranged in the mounting hole, a probe 146 is threadedly connected with the tapered gear ring 143, and in a case that the motor 145 drives the fourth gear 144 to rotate, the fourth gear 144 drives the sleeve 142 to rotate, the tapered gear ring 143 moves in the axial direction of the rod body 1634 to drive the second pressure detection portion 150 to move in the axial direction of the rod body 1634 and drive the probe 146 to move in a radial direction of the rod body 1634.

The cover 141 is connected with the top end of the rod body 1634 to drive the cover 141 to move towards the baffle of the workpiece 200 by the rod body 1634 to apply a simulated drilling force to the baffle. The sleeve 142 is arranged below the cover 141 and abuts against the cover 141 to rotate relative to the cover 141. The middle portion of the sleeve 142 is provided with the tapered threaded hole, and the tip of the tapered threaded hole is away from the cover 141. The tapered gear ring 143 is screwed in the tapered threaded hole, and the direction of the tapered gear ring 143 is consistent with the direction of the tapered threaded hole. The second pressure detection portion 150 is arranged at one end of the tapered gear ring 143 towards the claw 122. The fourth gear 144 is sleeved on the sleeve 142, and the fourth gear 144 and the sleeve 142 rotate synchronously.

In this way, in the process of simulating drilling, the motor 145 can be started, the output shaft of the motor 145 drives the fourth gear 144 to rotate synchronously, the fourth gear 144 drives the sleeve 142 to rotate synchronously, thereby driving the tapered gear ring 143 to move towards the baffle, and in the process that the tapered gear ring 143 extends, the probe 146 is opened to contact the stepped hole wall of the baffle. In a case that the probe 146 presses against the stepped hole wall, the motor 145 stops moving to ensure that the drilling simulation device 140 is stable, reduce the movement, improve the stability, and make the drilling simulation device 140 applicable to stepped holes of various sizes to improve the applicability.

[0087] It can be understood that the probe 146 can be an open ring, or composed of multiple circular arc segments, to ensure the degree of opening and contraction. Exemplarily, the outer diameter size of the stepped hole suitable for the drilling simulation device 140 is 10mm to 20mm.

[0088] In some examples, the baffle-equipped rotary thin-walled part clamping and drilling deformation simulation detection system further comprises a controller, and the driving member 161, the first electromagnetic clutch 1644, the second electromagnetic clutch 1645, the first pressure detection portion 130 and the second pressure detection portion 150 are electrically connected to the controller; wherein, in the case of performing a simulation clamping operation, the controller controls the driving member 161 to start, controls the first electromagnetic clutch 1645 to be powered, the second gear 1642 drives the shaft shoulder screw to rotate, the shaft shoulder screw drives the clamping portion 120 to tighten the workpiece 200, and in the case that the clamping force value detected by the first pressure detection portion 130 reaches a preset clamping force value, the first electromagnetic clutch 1644 is controlled to be powered off; in the case of performing a simulation drilling operation, the controller controls the driving member 161 to start, controls the second electromagnetic clutch 1644 to be powered, the third gear 1643 drives the worm 1632 to rotate, the worm 1632 drives the worm nut 1633 to rotate, so that the rod body 1634 drives the drilling simulation device 140 to move towards the direction of approaching the baffle, to press the baffle, and in the case that the simulation drilling force value detected by the second pressure detection portion 150 reaches a preset drilling force value, the second electromagnetic clutch 1645 is controlled to be powered off.

[0089] It can be understood that the belt partition rotary body thin-walled part clamping and drilling deformation simulation detection system is also provided with a controller. The driving member 161, the first electromagnetic clutch 1644, the second electromagnetic clutch 1645, the first pressure detection part 130 and the second pressure detection part 150 are all electrically connected to the controller. In this way, in the case of simulation clamping operation, the controller controls the driving member 161 to start, controls the first electromagnetic clutch 1645 to be powered, the second gear 1642 drives the shaft shoulder screw to rotate, the shaft shoulder screw drives the clamping part 120 to tighten the workpiece 200, and in the case that the clamping force value detected by the first pressure detection part 130 reaches the preset clamping force value, the first electromagnetic clutch 1644 is controlled to be powered off; in the case of simulation drilling operation, the controller controls the driving member 161 to start, controls the second electromagnetic clutch 1644 to be powered, the third gear 1643 drives the worm 1632 to rotate, the worm 1632 rotates through the driving worm nut 1633 to drive the rod body 1634 to move the drilling simulation device 140 towards the partition, to press the partition, and in the case that the simulation drilling force value detected by the second pressure detection part 150 reaches the preset drilling force value, the second electromagnetic clutch 1645 is controlled to be powered off.

Further, the relationship between the obtained clamping force and the clamping deformation, and the relationship between the drilling force and the drilling deformation are accurate, to lay an accurate foundation for controlling the deformation of the belt partition rotary body thin-walled part.
