[0065] It can be understood that the clamping and drilling deformation simulation detection system of the thin-walled rotating body with partition provided in the embodiment of the present disclosure is provided with a support part 110, a clamping part 120, a first pressure detection part 130, a drilling simulation device 140, a second pressure detection part 150, an adjustment part 160 and a deformation detection part. Among them, the clamping part 120 is supported by the support part 110, and the workpiece 200 is clamped by the clamping part 120, and the workpiece 200 is a thin-walled rotating body with partition. The first pressure detection part 130 is arranged on the clamping part 120, and the clamping force applied to the workpiece 200 by the clamping part 120 is detected by the first pressure detection part 130. The drilling simulation device 140 applies pressure to the partition of the workpiece 200 according to the preset drilling force value to simulate drilling. The second pressure detection part 150 is arranged on the drilling simulation device 140, and the pressure value applied to the partition by the drilling simulation device 140 is detected by the second pressure detection part 150. The position of the clamping part 120 relative to the workpiece 200 is adjusted by the adjusting part 160. After the adjusting part 160 adjusts the clamping part 120 to abut against the workpiece 200, the adjusting part 160 adjusts the clamping part 120 to press against the workpiece 200 to apply a clamping force to the workpiece 200, thereby obtaining the clamping force value detected by the first pressure detecting part 130 to determine that the clamping force applied by the clamping part 120 to the workpiece 200 reaches a preset clamping force value; 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 The drilling simulation device 140 is adjusted to press the partition to apply a simulated drilling force to the workpiece 200, so as to determine 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 unit 150, so as to complete the clamping and drilling simulation of the workpiece 200. By detecting the actual clamping deformation and the actual drilling deformation of the workpiece 200 through the deformation detection unit, the relationship between the clamping force and the clamping deformation, as well as the relationship between the drilling force and the drilling deformation can be obtained, thereby laying a foundation for controlling the deformation of the thin-walled rotating body with a partition.

[0066] Exemplarily, the deformation detection unit may use a three-coordinate measuring machine.

[0067] In some examples, such as Figure 1 and Figure 2 As shown, the support portion 110 includes: a base 111 ; a support column 112 disposed on the base 111 ; a flange 113 covered on the support column 112 , and the clamping portion 120 is disposed on the flange 113 .

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

[0069] Exemplarily, four support columns 112 are provided, and the four support columns 112 are arranged in a circular array, and the angles between adjacent support columns 112 are all 90°.

[0070] In some examples, such as Figure 1 and Figure 2 As shown, the clamping portion 120 includes: a chuck 121, which is arranged at the end of the flange 113 away from the support column 112; a claw 122, which is arranged on the chuck 121, and the claw 122 is used to press on the inner diameter of the clamping end of the workpiece 200 to tighten and fix the workpiece 200, and the adjusting portion 160 is used to adjust the position of the claw 122 relative to the workpiece 200; wherein the first pressure detecting portion 130 is arranged on the outer side of the clamping side of the claw 122, and the outer contour of the first pressure detecting portion 130 is in contact with the inner contour of the clamping end of the workpiece 200.

[0071] It is understandable that the clamping part 120 may be provided with a chuck 121 and a claw 122. The chuck 121 is provided at one end of the flange 113 away from the support column 112, and the claw 122 is provided on the chuck 121. The adjusting part 160 can adjust the claw 122 to move along the radial direction of the chuck 121, thereby adjusting the position of the claw 122 relative to the workpiece 200. When the adjusting part 160 adjusts the outer side of the claw 122 to press against the inner diameter of the clamping end of the workpiece 200, the workpiece 200 is tightened and fixed by the claw 122. And the first pressure detection part 130 is provided at one end of the claw 122 facing the workpiece 200, and the claw 122 drives the first pressure detection part 130 to press against the inner diameter of the clamping end of the workpiece 200, so as to detect the actual clamping force value through the first pressure detection part. When the actual clamping force value reaches the preset clamping force value, the clamping part 120 completes the clamping of the workpiece 200. 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 is fitted with the inner contour of the clamping end of the workpiece 200 .

[0072] In some examples, such as Figure 1 and Figure 2As shown, the adjustment part 160 includes: a driving member 161; a first adjustment member 162, connected to the chuck 121, for adjusting the expansion size of the claw 122; a second adjustment member 163, the base 111, the support column 112 and the flange 113 are surrounded to form a placement space, and the second adjustment member 163 is arranged in the placement space, for adjusting the drilling simulation device 140 to move towards or away from the partition; a switching member 164, for switching the first adjustment member 162 to be connected to the driving member 161, or switching the second adjustment member 163 to be connected to the driving member 161.

[0073] It is understandable that the adjustment part 160 may be provided with a driving member 161, a first adjusting member 162, a second adjusting member 163 and a switching member 164. Among them, the first adjusting member 162 is connected to the chuck 121, so that the expansion size of the claw 122 can be adjusted by 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 113, and the drilling simulation device 140 is adjusted to move toward or away from the partition by the second adjusting member 163. The first adjusting member 162 is switched to be connected to the driving member 161 or the second adjusting member 163 is switched to be connected to the driving member 161 by the switching member 164. With such a configuration, when performing a clamping operation on the workpiece 200, the switching member 164 is switched to the first adjusting member 162 connected to the driving member 161, and the driving member 161 drives the first adjusting member 162 to drive the claw 122 to move, so that the actual clamping force applied by the clamping portion 120 to the workpiece 200 reaches the preset clamping force. When simulating drilling operations, the switching member 164 is switched to the second adjusting member 163 connected to the driving member 161, and the driving member 161 drives the second adjusting member 163 to drive the drilling simulation device 140 to move in a direction close to the partition, so that the drilling simulation device 140 presses against the partition until the simulated drilling force value applied by the drilling simulation device 140 to the workpiece 200 reaches the preset drilling force value. In this way, the simulated clamping and drilling of the workpiece 200 are completed. The clamping deformation and drilling deformation of the workpiece 200 are detected by the deformation detection unit, and the relationship between the clamping force and the clamping deformation, as well as the relationship between the drilling force and the drilling deformation, can be obtained to lay a foundation for controlling the deformation of the thin-walled part of the rotating body with a partition. By setting the switching member 164, the first adjustment member 162 and the second adjustment member 163 are prevented from interfering with each other during adjustment, affecting the adjustment effect, and improving reliability.

[0074] In some examples, such as Figure 1 and Figure 2As shown, the first adjusting member 162 includes: a shoulder screw, a first bevel gear is arranged along the radial direction of the chuck 121, and the shoulder screw is connected to the first bevel gear; a second bevel gear is arranged along the axial direction of the chuck 121, and the end of the second bevel gear facing the flange 113 is meshed with the first bevel gear, and the end of the second bevel gear away from the flange 113 is provided with a plane thread, and the bottom end of the claw 122 is provided with a rack, and the rack is meshed with the plane thread; wherein, when the shoulder screw is switched to be connected to the driving member 161 through the switching member 164, the driving member 161 drives the shoulder screw to rotate, and the shoulder screw drives the first bevel gear to rotate.

[0075] It is understandable that the first adjusting member 162 is provided with a shoulder screw, a first bevel gear and a second bevel gear. Among them, the first bevel gear is provided radially of the chuck 121, and the chuck 121 is provided with a clamping groove radially, the shoulder screw is inserted in the clamping groove and connected to the first bevel gear, and the shoulder screw can rotate synchronously with the first bevel gear. The second bevel gear is arranged along the axial direction of the chuck 121, and the central axis of the second bevel gear coincides with the central axis of the chuck 121, the end of the second bevel gear facing the flange 113 is meshed with the first bevel gear, and the end of the second bevel gear facing away from the flange 113 is a plane thread, and the bottom end of the claw 122 is provided with a rack, and the rack is meshed with the plane thread. With such arrangement, when the workpiece 200 needs to be clamped, the switching member 164 switches to the shoulder screw connected to the driving member 161, the driving member 161 drives the shoulder screw to rotate, the shoulder screw drives the first bevel gear to rotate synchronously, thereby driving the second bevel gear to rotate along the axis direction of the chuck 121, the plane thread of the second bevel gear rotates, thereby driving the rack to move toward the inner diameter direction of the clamping end close to the workpiece 200, so that the claw 122 presses the inner diameter of the clamping end of the workpiece 200, and tightens and clamps the workpiece 200. When the workpiece 200 needs to be disassembled, the driving member 161 drives the shoulder screw to rotate in the opposite direction.

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

[0078] It can be understood that the second adjusting member 163 is provided with a housing 1631, a worm 1632, a worm wheel nut 1633 and a rod body 1634. The housing 1631 is arranged in the placement space, the worm 1632 is arranged in the housing 1631, and the driving end of the worm 1632 extends out of the housing 1631 and is located outside the support column 112, and the driving end of the worm 1632 is connected to the driving member 161. The worm wheel nut 1633 is arranged in the housing 1631, and the outer circle of the worm wheel nut 1633 is a worm gear mechanism, the worm gear mechanism is engaged with the worm 1632, the central through hole of the worm wheel nut 1633 is an internal thread mechanism, and the central axis of the worm wheel nut 1633 coincides with the axis of the chuck 121. The bottom end of the rod body 1634 is provided with a lead screw structure, which is engaged with the internal thread mechanism, and the rod body 1634 is inserted through the support portion 110 and the clamping portion 120, and the top end of the rod body 1634 is threadedly connected to the drilling simulation device 140.

When it is necessary to stop the simulated drilling, the driving member 161 drives the worm 1632 to rotate in the opposite direction.

[0079] Exemplarily, a through hole is opened at the center of the base 111 , and the lead screw structure of the rod body 1634 can be inserted into the through hole, and bearings 1635 are provided at both ends of the worm nut 1633 .

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

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

[0082] In some examples, such as Figures 1 to 3 As shown, the switching member 164 includes: a first gear 1641, which is sleeved on the output shaft of the driving member 161, and the first gear 1641 is used to rotate synchronously with the output shaft; a second gear 1642, which is sleeved on the shoulder screw, and the second gear 1642 is meshed with the first gear 1641; a third gear 1643, which is sleeved on the portion of the worm 1632 extending from the support column 112, and the third gear 1643 is meshed with the first gear 1641; a first electromagnetic clutch 1644, which is arranged between the shoulder screw and the second gear 1642. When the first electromagnetic clutch 1644 is energized, the first electromagnetic clutch 1644 is connected, and the first electromagnetic clutch 1644 is connected. The shoulder screw and the second gear 1642 rotate synchronously; when the first electromagnetic clutch 1644 is powered off, the first electromagnetic clutch 1644 is separated, and the shoulder screw and the second gear 1642 are clearance-matched; the second electromagnetic clutch 1645 is arranged between the worm 1632 and the third gear 1643, and when the second electromagnetic clutch 1645 is powered on, the second electromagnetic clutch 1645 is connected, and the worm 1632 and the third gear 1643 rotate synchronously; when the second electromagnetic clutch 1645 is powered off, the second electromagnetic clutch 1645 is separated, and the worm 1632 and the third gear 1643 are clearance-matched.

[0083] It can be understood that the switching member 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 member 161, and the output shaft of the driving member 161 can drive the first gear 1641 to rotate synchronously. The second gear 1642 is sleeved on the shoulder screw, and the second gear 1642 and the shoulder screw are clearance-matched. The third gear 1643 is sleeved on the driving end of the worm 1632, and the third gear 1643 and the worm 1632 are clearance-matched. The first electromagnetic clutch 1644 is arranged between the shoulder screw and the second gear 1642. When the first electromagnetic clutch 1644 is in a connected state, the shoulder screw and the second gear 1642 rotate synchronously; when the first electromagnetic clutch 1644 is in a disconnected state, the shoulder screw and the second gear 1642 are clearance-matched. The second electromagnetic clutch 1645 is arranged between the worm 1632 and the third gear 1643. When the second electromagnetic clutch 1645 is in a connected state, the worm 1632 and the third gear 1643 rotate synchronously; when the second electromagnetic clutch 1645 is in a disconnected state, the worm 1632 and the third gear 1643 are clearance-matched. With such arrangement, when performing a simulated clamping operation, the first electromagnetic clutch 1644 is controlled to be connected and the second electromagnetic clutch 1645 is disconnected, so that the driving member 161 drives the shoulder screw to rotate to adjust the distance between the claw 122 and the workpiece 200 and the clamping force applied to the workpiece 200; when performing a simulated drilling operation, the second electromagnetic clutch 1645 is controlled to be connected and the first electromagnetic clutch 1644 is disconnected, so that the driving member 161 drives the worm 1632 to rotate to adjust the distance between the drilling simulation device 140 and the workpiece 200 and the simulated cutting force applied to the workpiece 200. In this way, the first adjusting member 162 and the second adjusting member 163 are prevented from interfering with each other during adjustment, affecting the adjustment effect, and improving reliability.

[0084] For example, Figure 3 As shown, the first electromagnetic clutch 1644 and the second electromagnetic clutch 1645 can both use electromagnetic spline 1646. The keyway of electromagnetic spline 1646 is N-level. When electromagnetic spline 1646 is energized, the magnetism is S, that is, the spline and the keyway are attracted to each other, the spline extends out and fits with the keyway clearance; when electromagnetic spline 1646 is de-energized, the magnetism is N, the keyway and the spline repel each other, and the spline retracts.

[0085] In some examples, such as Figure 4As shown, the drilling simulation device 140 comprises: a cover body 141, the top end of the rod body 1634 is threadedly connected to the cover body 141; a sleeve 142, abutting against one end of the cover body 141 facing the claw 122, a tapered threaded hole is provided in the middle of the sleeve 142, and the tip of the tapered threaded hole is away from the cover body 141; a tapered gear ring 143, screwed on the tapered threaded hole, and the second pressure detection part 150 is arranged at one end of the tapered gear ring 143 facing the claw 122; a fourth gear 144, sleeved on the sleeve 142, and the fourth gear 144 is arranged along the upper A mounting hole is provided in the axial direction of the rod body 1634; a motor 145, and an output shaft of the motor 145 is arranged in the mounting hole; a probe 146 is threadedly connected to the conical gear ring 143; wherein, when the motor 145 drives the fourth gear 144 to rotate, the fourth gear 144 drives the sleeve 142 to rotate, and the conical gear ring 143 moves along the axial direction of the rod body 1634, so as to drive the second pressure detection part 150 to move along the axial direction of the rod body 1634, and drive the probe 146 to move radially along the rod body 1634.

[0086] It is understandable that the drilling simulation device 140 is provided with a cover body 141, a sleeve 142, a conical gear ring 143, a fourth gear 144, a motor 145 and a probe 146. Among them, the cover body 141 is connected to the top of the rod body 1634, so that the cover body 141 is driven by the rod body 1634 to move toward the partition close to the workpiece 200, so as to apply a simulated drilling force to the partition. The sleeve 142 is arranged below the cover body 141, abuts against the cover body 141, and can rotate relative to the cover body 141. A conical threaded hole is opened in the middle of the sleeve 142, and the tip of the conical threaded hole is away from the cover body 141. The conical gear ring 143 is screwed into the conical threaded hole, and the direction of the conical gear ring 143 is consistent with the direction of the conical threaded hole. The second pressure detection part 150 is arranged at one end of the conical gear ring 143 facing the claw 122. The fourth gear 144 is sleeved on the sleeve 142, and the fourth gear 144 and the sleeve 142 rotate synchronously. The fourth gear 144 is provided with a mounting hole along the axial direction of the rod body 1634, the output shaft of the motor 145 is arranged in the mounting hole, and the probe 146 is threadedly connected to the conical gear ring 143. In this way, during 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, and the fourth gear 144 drives the sleeve 142 to rotate synchronously, thereby driving the conical gear ring 143 to move toward the partition. During the extension of the conical gear ring 143, the probe 146 will be driven to open until it contacts the stepped hole wall of the partition. When the probe 146 presses against the stepped hole wall, the motor 145 stops moving, so as to ensure the stable position of the drilling simulation device 140, reduce the movement, improve the stability, and make the drilling simulation device 140 applicable to stepped holes of various sizes, thereby improving the applicability.

[0087] It is understandable that the probe 146 may be an open ring, or may be composed of a plurality of arc segments, so as to ensure the degree of opening and contraction. For example, the outer diameter of the stepped hole applicable to the drilling simulation device 140 is 10 mm to 20 mm.

[0088] In some examples, the thin-walled part clamping and drilling deformation simulation detection system of the rotating body with a partition further includes: a controller, the driving member 161, the first electromagnetic clutch 1644, the second electromagnetic clutch 1645, the first pressure detection unit 130 and the second pressure detection unit 150 are all electrically connected to the controller; wherein, in the case of a simulated clamping operation, the controller controls the driving member 161 to start, controls the first electromagnetic clutch 1645 to be energized, the second gear 1642 drives the shoulder screw to rotate, the shoulder screw drives the clamping unit 120 to tighten the workpiece 200, and the clamping detected by the first pressure detection unit 130 When the force value reaches the preset clamping force value, the first electromagnetic clutch 1644 is controlled to be powered off; when performing simulated drilling operations, the controller controls the driving member 161 to start, controls the second electromagnetic clutch 1644 to be powered on, and the third gear 1643 drives the worm 1632 to rotate. The worm 1632 drives the worm wheel nut 1633 to rotate, so that the rod body 1634 drives the drilling simulation device 140 to move toward the direction close to the partition to press the partition. When the simulated drilling force value detected by the second pressure detection unit 150 reaches the preset drilling force value, the second electromagnetic clutch 1645 is controlled to be powered off.

[0089] It is understandable that the thin-walled component clamping and drilling deformation simulation detection system of the rotating body with partition is also provided with a controller. The driving member 161, the first electromagnetic clutch 1644, the second electromagnetic clutch 1645, the first pressure detection unit 130 and the second pressure detection unit 150 are all electrically connected to the controller. With such arrangement, when performing a simulated clamping operation, the controller controls the driving member 161 to start, controls the first electromagnetic clutch 1645 to be energized, and the second gear 1642 drives the shoulder screw to rotate, and the shoulder screw drives the clamping part 120 to tighten the workpiece 200. When the clamping force value detected by the first pressure detection part 130 reaches a preset clamping force value, the first electromagnetic clutch 1644 is controlled to be de-energized; when performing a simulated drilling operation, the controller controls the driving member 161 to start, controls the second electromagnetic clutch 1644 to be energized, and the third gear 1643 drives the worm 1632 to rotate, and the worm 1632 rotates by driving the worm wheel nut 1633, so that the rod body 1634 drives the drilling simulation device 140 to move toward the direction close to the partition to press the partition. When the simulated drilling force value detected by the second pressure detection part 150 reaches a preset drilling force value, the second electromagnetic clutch 1645 is controlled to be de-energized. This improves the degree of automation, ensures that the simulated clamping force and simulated drilling force data are more accurate, improves reliability, and ensures that the clamping deformation and drilling deformation data detected by the subsequent deformation detection unit are accurate. This ensures that the relationship between the clamping force and the clamping deformation, as well as the relationship between the drilling force and the drilling deformation, are accurate, laying an accurate foundation for controlling the deformation of the thin-walled parts of the rotating body with partitions.
