DETAILED DESCRIPTION

[0043] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0046] In some related technologies, large components are processed using large machine tools. However, the number of large machine tools and the processing resources they can provide are limited, and the manufacturing cost of the equipment is high, which cannot meet the growing demand for multi-variety and small-batch processing of large components.

[0047] Based on this, the present application proposes a component processing system capable of large-scale movement and local fine processing, so as to achieve local high-quality cutting processing of large components.

[0048] The component processing system 100 according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0049] 1-15 , a component processing system 100 according to an embodiment of the present application may include: a positioning mechanism 10 , a processing mechanism 20 and an auxiliary tooling 30 .

[0050] Specifically, the positioning mechanism 10 includes a positioning base 11, a first transverse moving member 12, a longitudinal moving member 13, and a second transverse moving member 14. The first transverse moving member 12 is movably mounted on the positioning base 11 along a first transverse direction, the longitudinal moving member 13 is movably mounted on the first transverse moving member 12 along a longitudinal direction, and the second transverse moving member 14 is movably mounted on the longitudinal moving member 13 along a second transverse direction. The first transverse direction, the second transverse direction, and the longitudinal direction intersect in pairs, such as being perpendicular to each other. For example, in the example shown in Figure 1, the first transverse direction is the left-right direction, the second transverse direction is the front-back direction, and the longitudinal direction is the up-down direction.

[0051] It is worth noting that in the description of this application, the horizontal direction includes but is not limited to the horizontal direction, such as a direction that has a certain angle (such as a 30° angle) with the horizontal direction. Similarly, the longitudinal direction includes but is not limited to the vertical direction, and can also be a direction that has a certain angle with the vertical direction.

[0052] The first transverse moving member 12 , the longitudinal moving member 13 and the second transverse moving member 14 move respectively along three directions intersecting each other, so that the second transverse moving member 14 of the positioning mechanism 10 can achieve a wide range of movement and preliminary positioning.

[0053] The machining mechanism 20 includes a machining base 21, a spindle assembly 22, and a pressure member 23. The machining base 21 is mounted on the second transverse moving member 14. The spindle assembly 22 is movably connected to the machining base 21 and is used to machine the component 40, such as drilling, cutting, and other machining operations. The pressure member 23 is movably connected to the machining base 21 and is used to contact and cooperate with the component 40. The spindle assembly 22 and the pressure member 23 can move independently.

[0054] For example, in some embodiments, the spindle assembly 22 includes a spindle 221 and a spindle motor 222. The spindle motor 222 drives the spindle 221 to rotate. The spindle 221 can be a tool, a drill bit, or the like, or the spindle 221 can be used to mount a tool, a drill bit, or the like. The relative motion between the spindle assembly 22 and the machining base 21 includes at least one of rotation and translation. For example, the spindle 221 rotates relative to the machining base 21 under the drive of the spindle motor 222, and the spindle assembly 22 moves axially as a whole to achieve axial feed, etc.

[0055] Furthermore, the movement of the spindle assembly 22 and the movement of the pressure member 23 toward the component 40 do not affect each other, allowing the pressure member 23 to cooperate with the component 40 when the spindle assembly 22 is not feeding, or to cooperate with the component 40 before the spindle assembly 22 is feeding. For example, the pressure member 23 can contact the component 40 when the spindle assembly 22 is not feeding to facilitate distance detection between the pressure member 23 and the component 40; for another example, the pressure member 23 can press the component 40 before the spindle assembly 22 feeds, so that during the feeding operation of the main assembly 40, the pressure member 23 and the component 40 cooperate to reduce deformation of the component 40 surface caused by local low stiffness.

[0056] The auxiliary fixture 30 is located on one side of the positioning mechanism 10 along the second transverse direction and is used to secure the component 40. Unlike large machine tools in related art, the component 40 and the processing mechanism 20 are respectively mounted on the auxiliary fixture 30 and the positioning mechanism 10. This facilitates greater flexibility and variability in the relative positions of the component 40 and the processing mechanism 20, thereby meeting the processing requirements of components 40 of various sizes, such as large components 40. The overall size of the component processing system 100 is not easily restricted by the size of the component 40, thereby facilitating a reduction in the volume and cost of the component processing system 100.

[0057] In some specific embodiments, as shown in Figures 1 and 6, the first transverse moving member 12 in the positioning mechanism 10 is movably mounted on the positioning base 11 along the first transverse direction, the longitudinal moving member 13 is movably arranged in the installation space of the first transverse moving member 12 along the longitudinal direction, and the second transverse moving member 14 is movably arranged above the longitudinal moving member 13 along the second transverse direction, thereby enabling the positioning mechanism 10 to achieve a wide range of movement in the first transverse, longitudinal, and second transverse directions. At the same time, the second transverse moving member 14 in the positioning mechanism 10 is connected to the processing base 211 in the processing mechanism 20, enabling the processing mechanism 20 to achieve a wide range of movement in the first transverse, longitudinal, and second transverse directions together with the positioning mechanism 10, which is beneficial for the processing mechanism 20 to initially locate the points to be processed on the component 40.

[0058] In addition, as shown in Figures 1, 7-8 and 11-13, the pressure member 23 in the processing mechanism 20 is movably connected to the processing base 211, and can both extend to contact the mechanism 20 to be processed and retract to restore to its initial state; the spindle assembly 22 is movably connected to the processing base 211, and can both extend to perform processing operations such as drilling on the point to be processed of the component 40, and retract to restore to its initial state, waiting for the next processing or the processing of the next point to be processed.

[0059] According to the component processing system 100 of the embodiment of the present application, the first transverse moving member 12, the longitudinal moving member 13 and the second transverse moving member 14 cooperate to enable the processing mechanism 20 to achieve a large range of movement in the first transverse, longitudinal and second transverse directions, thereby meeting the processing requirements of components 40 of more sizes, and through the independent movement of the pressure member 23 and the spindle assembly 22, a richer working mode can be achieved, which is conducive to achieving local high-quality processing operations.

[0060] In some embodiments of the present application, as shown in Figures 7-8 and 11-13, the processing mechanism 20 further includes a first driving member 213 and a second driving member 215. The first driving member 213 is mounted on the processing base 21 and includes a first telescopic portion 214. The outer circumference of the pressure member 23 is provided with a first connecting portion 231, and the first telescopic portion 214 is connected to the first connecting portion 231 to drive the pressure member 23 to move axially. The second driving member 215 is mounted on the processing base 21 and includes a second telescopic portion 216. The outer circumference of the spindle assembly 22 is provided with a second connecting portion 223. The second telescopic portion 216 is connected to the second connecting portion 223 to drive the spindle assembly 22 to move axially.

[0061] According to some specific embodiments of the present application, as shown in Figures 7-8 and 11-13, the first driving member 213 can be a cylinder or an electric push rod, and the second driving member 215 can be an electric push rod. The electric push rod has motion accuracy along the axis direction and can meet the drilling accuracy requirements. The first driving member 213 and the second driving member 215 can be the same or different.

[0062] When the first driving member 213 is in operation, the first telescopic portion 214 extends outward, pushing the first connecting portion 231 on the outer circumference of the pressure member 23, causing the pressure member 23 to move toward the component 40 and contact the surface of the component 40. For example, during processing of the component 40, the pressure member 40 can be pressed to limit the position to reduce the possibility of deformation of the component 40 surface due to low local rigidity; or the contact with the component 40 can realize functions such as position detection and distance detection. Of course, when the first telescopic portion 214 contracts, it can drive the pressure member 23 to move in the opposite direction to separate from the component 40, so that it can be extended again to perform the next operation.

[0063] When the second driving member 215 is working, the second telescopic portion 216 extends outward, and by pushing the second connecting portion 223 on the outer peripheral surface of the spindle assembly 22, the spindle assembly 22 moves axially, thereby causing the spindle assembly 22 to extend outward to achieve the feeding operation. For example, in some specific embodiments, as shown in Figures 11 to 13, the spindle assembly 22 includes a spindle motor 222 and a spindle 221. The second driving member 215 drives the spindle motor 222 and the spindle 221 to move toward the component 40 to achieve feeding. At the same time, the spindle motor 222 can drive the spindle 221 to rotate. The two cooperate to achieve processing operations such as drilling of the component 40. Of course, when the second driving member 215 contracts, it can drive the spindle assembly 22 to move in the opposite direction to separate from the component 40, so that it can be extended again to achieve the next processing.

[0064] Therefore, the first driving member 213 provides driving force for the movement of the pressure member 23, and the second driving member 215 provides driving force for the movement of the spindle assembly 22, so that the pressure member 23 and the spindle assembly 22 can move independently to respectively realize the processing operations on the component 40, and can cooperate to realize the processing operations on the component 40, which is conducive to making the processing operations more diversified.

[0065] In some embodiments of the present application, as shown in Figures 11-13, the second connecting portion 223 is disposed at an end of the first driving member 213 proximal to the member 40 (e.g., the front end as shown in Figure 11), the pressure member 23 is located on a side of the second connecting portion 223 facing the member 40 (e.g., the front side as shown in Figure 11), and the main shaft 221 of the main shaft assembly 22 is disposed through the pressure member 23. That is, when the first driving member 213 drives the pressure member 23 to extend, the main shaft assembly 22 can remain stationary as shown in Figure 12, or can extend outward under the drive of the second driving member 215 as shown in Figure 13, i.e., the movement of the pressure member 23 is not affected by the main shaft assembly 22. Similarly, when the main shaft 221 of the main shaft assembly 22 moves, for example, when it rotates under the drive of the spindle motor 222, the pressure member 23 can remain stationary or can extend outward under the drive of the first driving member 213 as shown in Figure 12, i.e., the movement of the main shaft 221 and the pressure member 23 are independent of each other, and the movement of the main shaft 221 is not affected by the pressure member 23.

[0066] In some embodiments of the present application, as shown in Figures 7 to 10, the processing base 21 includes a first base 211, a second base 212 and five branches. The first base 211 is connected to the second transverse moving member 14, so that the processing base 21 can move over a large range in the second transverse direction with the second transverse moving member 14 to perform preliminary positioning. Each branch is connected to the first base 211 by a first hinge 241 at which two axes intersect, one of which (herein, the first branch 24) is connected to the second base 212 by a second hinge 242, and the other four branches (respectively designated as the second branch 25, the third branch 26, the fourth branch 27 and the fifth branch 28) are connected to the second base 212 by a third hinge 251 at which two axes intersect. The branch chain includes a branch chain driving member 243 and a branch chain screw rod 244. The branch chain driving member 243 is connected to the first hinge 241, and the branch chain screw rod 244 is connected to the second hinge 242. The branch chain driving member 243 and the branch chain screw rod 244 are threadedly matched, and the branch chain driving member 243 is used to drive the branch chain screw rod 244 to axially extend and retract.

[0067] In some embodiments of the present disclosure, the first branch chain 24 is connected to the first base 211 and the second base 212 via a first hinge 241 and a second hinge 242, respectively. The second branch chain 25, the third branch chain 26, the fourth branch chain 27, and the fifth branch chain 28 have the same structure and are connected to the first base 211 and the second base 212 via a second hinge 242 and a third hinge 251, respectively. The five branches cooperate with the first base 211 and the second base 212 to form a closed loop structure. The first branch chain 24, the second branch chain 25, the third branch chain 26, the fourth branch chain 27, and the fifth branch chain 28 are driven by the branch chain driving member 243 to perform coordinated telescopic movement, thereby enabling the second base 212 to achieve five degrees of freedom of motion, specifically three translational degrees of freedom and two rotational degrees of freedom, namely translation along the first transverse direction, the longitudinal direction, and the second transverse direction, and rotation about the first transverse direction and the second transverse direction.

[0068] In addition, the spindle assembly 22, the first drive member 213 and the second drive member 215 are all arranged on the second base 212, so that the second base 212 can achieve five degrees of freedom of movement, thereby driving the spindle assembly 22 to achieve five degrees of freedom of movement, and realizing precise positioning and adjustment of the spindle assembly 22 to meet the complex processing requirements such as the large size of large components 40, variable angles of free-form surfaces, and stacking characteristics, effectively improving the operation complexity and processing accuracy.

[0069] In some embodiments of the present application, as shown in Figures 7 and 8, in the axial direction of the main shaft assembly 22, the five first hinges 241 are of equal height, the second hinge 242 and two of the third hinges 251 are of equal height and are all connected to the lower portion of the second base 212, and the other two third hinges 251 are of equal height and are both connected to the upper portion of the second base 212. Here, a higher height means that the distance between the hinge and the component 40 in the axial direction of the main shaft assembly 22 is greater, and a lower height means that the distance between the hinge and the component 40 in the axial direction of the main shaft assembly 22 is smaller. The difference in height of each revolute pair allows each branch chain to achieve telescopic movement in different directions in three-dimensional space, and is more conducive to the control of the position and posture of the main shaft assembly 22 by each branch chain.

[0070] In some embodiments of the present application, as shown in Figures 7 and 8, in the circumferential direction of the main shaft assembly 22, the second hinge 242 with a lower height and the two third hinges 251 (for example, the third hinge 251 corresponding to the second branch 25 and the fifth branch 28 shown in Figure 8) are evenly spaced, and the two third hinges 251 with a higher height (for example, the third hinge 251 corresponding to the third branch 26 and the fourth branch 27 shown in Figure 8) are respectively located between the second hinge 242 and the third hinge 251 with a higher height. This arrangement reduces the number of branches required for the posture adjustment of the main shaft assembly 22, and the forces exerted by each branch on the second base 212 are more uniform and orderly, facilitating precise control of the five degrees of freedom, and thus precise control of the position and posture of the main shaft assembly 22. At the same time, the installation of the branches is also more convenient.

[0071] In some embodiments of the present disclosure, the first branch chain 24 includes: a branch chain screw 244, a branch chain drive 243, a first hinge 241, and a second hinge 242. The branch chain screw 244 is threadedly connected to the branch chain drive 243, and the branch chain drive 243 can be a hollow motor that drives the branch chain screw 244 to extend and retract. The first hinge 241 is a U-joint, or universal joint, consisting of a revolute pair with two mutually perpendicular axes. The first hinge 241 includes an inner ring 245, an intermediate ring 246, and a fixed ring 247. The fixed ring 247 is connected to the first base 211, and the intermediate ring 246 and the fixed ring 247 can rotate relative to each other about the tangent direction of the main shaft assembly 22. The inner ring 245 is connected to the branch chain drive 243, and the inner ring 245 and the intermediate ring 246 can rotate relative to each other about the radial direction of the main shaft assembly 22. The second hinge 242 is connected to the second base 212 via a revolute pair with a rotation axis parallel to the tangent of the main shaft assembly 22. The first hinge 241 of the second, third, fourth and fifth branches has the same structure as the first hinge 241 of the first branch. The structure of the third hinge 251 has one more degree of freedom of radial rotation around the main shaft assembly 2 than the second hinge 242. The above branches have the advantages of light weight, high rigidity and high flexibility.

[0072] In some embodiments of the present application, as shown in Figures 1-2 and 6, the positioning base 11 is provided with a first slide rail 111 extending along the first transverse direction, and the first slide rail 111 is provided with stoppers 113 at both ends along the first transverse direction. A first slider 112 is provided at the bottom of the first transverse moving member 12, and the first slider 112 is slidable along the first slide rail 111 between the two stoppers 113. The first transverse moving member 12 can achieve a large range of movement in the first transverse direction to perform preliminary positioning of the processing mechanism 20 by sliding the first slider 112 at the bottom along the first slide rail 111 on the positioning base 11 along the first transverse direction. At the same time, the stoppers 113 at both ends of the first slide rail 111 can limit the moving stroke of the first transverse moving member 12 to prevent the first transverse moving member 12 from falling.

[0073] In some specific embodiments, as shown in Figures 1-2 and 6, the positioning base 11 further includes shims 114 and weight-reducing holes 115. As shown in Figure 2, the shims 114 are arranged around the bottom of the positioning base 11 to reduce vibration generated by the component processing system 100 during processing. The weight-reducing holes 115 are arranged around the four sides of the positioning base 11 to reduce the weight of the positioning base 11 and reduce costs.

[0074] In some embodiments of the present application, as shown in Figures 1, 3 and 6, the first transverse moving member 12 is provided with an installation space 121 extending in the longitudinal direction, and the installation space 121 penetrates the first transverse moving member 12 along the second transverse direction. The first transverse moving member 12 is provided with a second slide rail 122 along at least one side of the second transverse direction, and the second slide rail 122 extends in the longitudinal direction. The longitudinal moving member 13 is arranged in the installation space 121 and is slidably engaged with the second slide rail 122 through the second slider 123. The first transverse moving member 12 is provided with a first motor 124 and a first lead screw 125, the first lead screw 125 extends in the longitudinal direction and is threadedly engaged with the longitudinal moving member 13. The first motor 124 is connected to the first lead screw 125 and is used to drive the first lead screw 125 to rotate. The first lead screw 125 rotates to drive the longitudinal moving member 13 to move in the longitudinal direction, thereby realizing a large-scale movement of the positioning mechanism 10 in the longitudinal direction to perform preliminary positioning of the processing mechanism 20.

[0075] In some specific embodiments, as shown in Figures 4 and 6, the first transverse moving member 12 is provided with second slide rails 122 on both sides along the second transverse direction, and the longitudinal moving member 13 is provided with second sliders 123 on both sides along the second transverse direction, so that the longitudinal moving member 13 can be movably arranged in the installation space 121 of the first transverse moving member 12. The longitudinal moving member 13 is provided with first nuts 134 on both sides along the first transverse direction. The first nut 134 is threadedly engaged with the first lead screw 125 on the first transverse moving member 12. When the first motor 124 drives the first lead screw 125 to rotate, the first nut 134 drives the longitudinal moving member 13 to move along the axial direction of the first lead screw 125. At the same time, the longitudinal moving member 13 is guided by the second sliders 123 and the second slide rails 122, so that the longitudinal moving member 13 can achieve stable longitudinal movement within the installation space 121.

[0076] In some embodiments of the present application, as shown in Figures 1 and 4 to 6, the longitudinal moving member 13 and the second transverse moving member 14 are slidably engaged with the third slide rail 141 via a third slider 131, and the third slide rail 141 extends along the second transverse direction. One of the third slider 131 and the third slide rail 141 is arranged on the longitudinal moving member 13 and the other is arranged on the second transverse moving member 14. The longitudinal moving member 13 is provided with a second motor 132 and a second lead screw 133, the second lead screw 133 extends along the second transverse direction and is threadedly engaged with the second transverse moving member 14 via a second nut 135, the second motor 132 is connected to the second lead screw 133 and is used to drive the second lead screw 133 to rotate, and the second lead screw 133 rotates to drive the second transverse moving member 14 to move along the second transverse direction.

[0077] For example, as shown in Figures 4-6, the longitudinal moving member 13 is provided with a fixed third slider 131, and the second transverse moving member 14 is provided with a third slide rail 141. The third slider 131 has a groove extending along the second transverse direction. The third slide rail 141 is an elongated protrusion extending along the second direction. The elongated protrusion is embedded in the groove and can slide along the groove, so that the second transverse moving member 14 is movably arranged on the longitudinal moving member 13. At the same time, the longitudinal moving member 13 is provided with a second nut 135. The second nut 135 is threadedly connected to the second lead screw 133 on the longitudinal moving member 13 and fixedly connected to the second transverse moving member 14. When the second motor 132 on the longitudinal moving member 13 drives the second lead screw 133 to rotate, the second nut 135 on the second lead screw 133 can move along the axial direction of the second lead screw 133. At this time, the second transverse moving member 14 is guided by the third slide rail 141 and the third slider 131, so that the second transverse moving member 14 can be stably moved along the second transverse direction on the longitudinal moving member 13.

[0078] In some embodiments of the present application, as shown in Figures 1 and 14, the auxiliary tooling 30 is arranged independently from the positioning mechanism 10, wherein the auxiliary tooling 30 is used to fix the component 40 to be processed. The independent arrangement makes the installation of the component 40 more convenient, avoids the situation where the component 40 cannot be installed due to limited installation space, gets rid of the limitation of the working space of traditional processing machine tools, and can meet the fixing and processing needs of larger-sized components 40.

[0079] In some embodiments of the present application, as shown in Figures 1, 7-8, and 11-13, the pressure member 23 is provided with a plurality of distance detection members 232. The plurality of distance detection members 232 are spaced apart along the circumference of the pressure member 23 and are used to detect the distance between the pressure member 23 and the component 40. The spindle assembly 22 is adapted to adjust the axis angle based on the detection results of the plurality of distance detection members 232. For example, the distance detection member 232 may be a laser rangefinder or the like.

[0080] Specifically, multiple distance detection parts 232 work together to detect the distance from the component 40 in three-dimensional space, so as to judge the actual normal direction of the point to be processed based on the detection results, and then control the spindle assembly 22 through five branches to make precise adjustments in five degrees of freedom, so that the axial direction of the spindle 221 is consistent with the actual normal direction of the point to be processed.

[0081] Thus, the component processing system 100 can meet the processing requirements of components 40 with complex structural features such as free-form surfaces, and facilitate local high-quality processing requirements. For example, during drilling, the coaxiality between the drilling axis and the normal line of the processing point can be improved.

[0082] In addition, in an embodiment where the pressure member 23 and the spindle assembly 22 can move independently, the pressure member 23 can move alone to drive the distance detection member 232 to move toward the component 40. The pressure member 23 contacts the surface of the component 40. At this time, the distance detection member 232 performs distance detection, which can improve the detection accuracy, and the detection process is not affected by the spindle assembly 22.

[0083] In some embodiments of the present application, as shown in Figures 7-8 and 11-13, there are three or more distance detection members 232. The surface of the pressure member 23 facing the component 40 includes a tapered surface, and the distance detection members 232 are disposed on the tapered surface. The tapered surface prevents the structure of the pressure member 23 from interfering with the distance detection process, thereby improving the accuracy of distance detection and increasing the coaxiality of the arrangement of the multiple distance detection members 232 with the axis of the spindle assembly 22.

[0084] In some specific embodiments, the component processing system 100 uses four distance detection components 232 for detection, wherein three distance detection components 232 can realize the detection of positions in three-dimensional space and calculate the normal direction of the point to be processed accordingly, while the fourth distance detection component 232 can realize the verification and calibration of the calculation results. Overall, the distance detection time of the component processing system 100 and the accuracy of the normal detection of the point to be processed can be shortened, thereby improving work efficiency.

[0085] According to an embodiment of the present application, the control method of the component processing system 100, as shown in FIG15 , includes the following steps:

[0086] S1: Install the component 40 onto the auxiliary tooling 30 .

[0087] S2 : Controlling the three-degree-of-freedom motion of the positioning mechanism 10 to position the spindle assembly 22 of the machining mechanism 20 opposite to the component 40 .

[0088] For example, as shown in Figures 1 and 6, the three degrees of freedom of the positioning mechanism 10 are respectively provided by the first transverse moving member 12, the longitudinal moving member 13 and the second transverse moving member 14. In some embodiments of the present disclosure, as shown in Figure 1, in the positioning mechanism 10, the first transverse moving member 12 is movable along the first transverse direction on the positioning base 11 through the guidance of the first slider 112 and the first slide rail 111, the longitudinal moving member 13 is driven by the first motor 124 to move along the longitudinal direction through the guidance of the second slider 123 and the second slide rail 122, and the second transverse moving member 14 is driven by the second motor 132 to move along the second transverse direction through the guidance of the third slider 131 and the third slide rail 141, thereby realizing three-degree-of-freedom movement, positioning the spindle assembly 22 of the processing mechanism 20 opposite to the component 40, that is, moving it to the vicinity of the point to be processed of the component 40, to achieve preliminary positioning.

[0089] S3: Control the spindle assembly 22 to move relative to the machining base 21 so that the spindle 221 of the spindle assembly 22 is opposite to the point to be machined of the component 40 .

[0090] In some embodiments of the present application, as shown in Figures 7-8, five branches can rotatably realize the connection between the first base 211 and the second base 212, and the branch chain screw 244 is driven to rotate by the branch chain driving member 243 to realize the axial extension and contraction of the branch chain, thereby realizing the five-degree-of-freedom movement adjustment of the main shaft assembly 22, so that the axial direction of the main shaft 221 of the main shaft assembly 22 is consistent with the actual normal direction of the point to be processed of the component 40, and the end of the main shaft 221 is opposite to the point to be processed, so that the main shaft 221 can accurately act on the point to be processed when feeding.

[0091] S4: Control the pressure member 23 to extend to press the surface of the component 40 .

[0092] In some embodiments of the present application, as shown in Figure 12, the first driving member 213 of the processing mechanism 20 drives the first telescopic part 214 to extend, and the first telescopic part 214 is connected to the first connecting part 231 to push the first connecting part 231 to move outward, and the first connecting part 231 is connected to the pressure member 23 to drive the pressure member 23 to extend, thereby pressing the surface of the component 40 to limit and support the component 40 to prevent the component 40 from moving or deforming during the processing process.

[0093] S5: Control the spindle assembly 22 to feed in the axial direction to achieve processing operations on the component 40.

[0094] In some embodiments of the present application, as shown in Figure 13, the second driving member 215 of the processing mechanism 20 drives the second telescopic part 216 to extend, and the second telescopic part 216 is connected to the second connecting part 223 to push the second connecting part 223 to move outward, and the second connecting part 223 is connected to the spindle assembly 22 so that the spindle assembly 22 is fed axially. At the same time, the spindle motor 222 drives the spindle 221 to rotate, thereby realizing the processing operation of the spindle 221 on the component 40.

[0095] According to the control method of the component processing system 100 of the embodiment of the present application, the processing mechanism 20 can achieve a large range of movement in the first lateral, longitudinal and second lateral directions to meet the processing requirements of components 40 of more sizes, and through the independent movement of the pressure member 23 and the spindle assembly 22, a richer working mode can be achieved, which is conducive to achieving local high-quality processing operations.

[0096] According to some embodiments of the present application, as shown in FIG15 , before step S4, the control method of the component processing system 100 further includes the following steps:

[0097] S6 : Control the pressure member 23 to extend and contact the surface of the component 40 .

[0098] In some embodiments of the present application, as shown in FIG. 12 , the first driving member 213 drives the pressure member 23 to extend through the first telescopic portion 214 and the first connecting portion 231 , so that the pressure member 23 can contact the surface of the component 40 .

[0099] S7: Detect the normal direction of the point to be processed.

[0100] In some embodiments of the present application, as shown in FIG12 , three or more distance detecting members 232 are arranged on the conical portion of the pressure member 23 facing the surface of the component 40. Specifically, the number of distance detecting members 232 can be four. When the first driving member 213 controls the pressure member 23 to extend and contact the surface of the component 40, the distance detecting members 232 on the pressure member 23 begin to detect the distance to the point to be processed on the surface of the component 40. Three of the distance detecting members 232 determine the normal direction of the point to be processed, and the fourth distance detecting member 232 verifies and calibrates the detected normal direction to improve the accuracy of the normal direction detection.

[0101] S8: Control the pressure member 23 to contract, and control the spindle assembly 22 to move relative to the processing base 21, so that the axis direction of the spindle assembly 22 coincides with the normal direction of the point to be processed, and the spindle 221 is opposite to the point to be processed.

[0102] In some embodiments of the present application, as shown in Figures 11-12, after the normal direction of the point to be processed is detected, the pressure member 23 is controlled to retract by the first driving member 213, and then the five branches are used to control the movement of the spindle assembly 22 relative to the processing base 21 to achieve precise adjustment of five degrees of freedom, so that the axial direction of the spindle 221 of the spindle assembly 22 coincides with the actual normal direction of the point to be processed of the component 40, and the spindle 221 is opposite to the point to be processed, so as to avoid the spindle assembly 22 finding the wrong point to be processed when feeding axially to perform the processing operation on the component 40.

[0103] The component processing system 100 and the control method thereof according to a specific embodiment of the present application are described in detail below with reference to the accompanying drawings. It is worth noting that the following description is merely illustrative and should not be construed as limiting the application.

[0104] As shown in FIG. 1 to FIG. 14 , a component processing system 100 according to a specific embodiment of the present application includes a positioning mechanism 10 , a processing mechanism 20 and an auxiliary tooling 30 .

[0105] The positioning mechanism 10 includes a positioning base 11, a first transverse moving member 12, a longitudinal moving member 13, and a second transverse moving member 14. The positioning base 11 supports the first transverse moving member 12, the longitudinal moving member 13, the second transverse moving member 14, and the processing mechanism 20. As shown in Figures 1-2 and 6, a plurality of shims 114 are evenly arranged on the bottom of the positioning base 11 to reduce vibration generated during processing operations of the component processing system 100, thereby making the component processing system 100 more stable. Furthermore, a plurality of weight-reducing holes 115 are evenly arranged around the positioning base 11 to reduce the weight of the positioning base 11 and improve operational stability. Furthermore, a first slide rail 111, a first slider 112, and a stopper 113 are disposed above the positioning base 11. The first slide rail 111 is slidably connected to the first slider 112, and the first slider 112 is fixedly connected to the first transverse moving member 12, allowing the first transverse moving member 12 to slide along the first slide rail 111 in the first transverse direction, thereby providing the positioning mechanism 10 with a degree of freedom along the first transverse direction and enabling a wide range of movement and preliminary positioning of the positioning mechanism 10 along the first transverse direction. Stoppers 113 are also disposed at both ends of the first slide rail 111 to control the movable range of the first transverse moving member 12 and effectively prevent it from sliding off the positioning base 11.

[0106] The first transverse moving member 12 is movably arranged on the positioning base 11 through the first slider 112. As shown in Figures 1, 3-4 and 6, the first transverse moving member 12 includes an installation space 121, a second slide rail 122, a first motor 124, a first screw 125 and a motor bracket 126. The installation space 121 is arranged longitudinally in the first transverse moving member 12 and passes through the first transverse moving member 12 along the second transverse direction for arranging the longitudinal moving member 13 and the second transverse moving member 14.

[0107] A first motor 124 and a motor bracket 126 are disposed at the longitudinal upper end of the first transverse moving member 12. The motor bracket 126 pulls the first motor 124, thereby reducing the operating vibration of the first motor 124 and enhancing the operating stability of the first motor 124. A first lead screw 125 disposed longitudinally on the longitudinal moving member 13 is connected to the first motor 124 at its upper end and is driven to rotate by the first motor 124. The first lead screw 125 is threadedly engaged with a first nut 134 located on the longitudinal moving member 13, thereby enabling the first nut 134 to move longitudinally.

[0108] In addition, second rails 122 are arranged on both sides of the first transverse moving member 12 along the second transverse direction. The second rails 122 are slidably connected to the second slider 123, and the second slider 123 is fixedly connected to the longitudinal moving member 13, so that the longitudinal moving member 13 can slide longitudinally on the second rails 122. To enhance the stability of longitudinal sliding, the first transverse moving member 12 is provided with two second rails 122 spaced apart along the first transverse direction. Therefore, the first motor 124 drives the first lead screw 125 to rotate, enabling the longitudinal moving member 13 to slide longitudinally on the first lead screw 125 along with the first nut 134. At the same time, the second slider 123 and the second rails 122 guide its longitudinal sliding, thus providing the positioning mechanism 10 with a degree of freedom in the longitudinal direction and enabling the positioning mechanism 10 to move over a large range and perform preliminary positioning in the longitudinal direction.

[0109] As shown in Figures 1 and 4 to 6, the longitudinal moving member 13 includes a third slider 131, a second motor 132, a second lead screw 133, a first nut 134, and a second nut 135. The first nut 134 is threadedly connected to the first lead screw 125 arranged on the first transverse moving member 12, thereby enabling the longitudinal moving member 13 to move longitudinally on the first transverse moving member 12. The second motor 132 drives the second lead screw 133 arranged on the longitudinal moving member 13 along the second transverse direction to rotate, and the second lead screw 133 is threadedly connected to the second nut 135. The second nut 135 is fixedly connected to the second transverse moving member 14, so that the second transverse moving member 14 moves along the second transverse direction with the second nut 135.

[0110] Furthermore, the third slider 131 is fixed to the longitudinal moving member 13 and is movably connected to a third slide rail 141 disposed on the second transverse moving member 14, thereby enabling the second transverse moving member 14 to move along the second transverse direction on the longitudinal moving member 13. Therefore, the second motor 132 drives the second lead screw 133 to rotate, enabling the second transverse moving member 14 to slide along the second lead screw 133 along the second transverse direction along with the second nut 135. Simultaneously, the third slide rail 141 and the third slider 131 cooperate to guide the sliding movement in the second transverse direction, thereby providing the positioning mechanism 10 with a degree of freedom along the second transverse direction and enabling a wide range of movement and preliminary positioning of the positioning mechanism 10 along the second transverse direction.

[0111] As shown in Figures 1, 4-6, and 7-8, the second transverse moving member 14 includes a third slide rail 141 and a base connection portion 142. The third slide rail 141 is movably connected to the third slider 131 disposed on the longitudinal moving member 13, enabling the second transverse moving member 14 to move along the second transverse direction on the longitudinal moving member 13. The base connection portion 142 is located at the front end of the second transverse moving member 14 and is used to connect the second transverse moving member 14 to the first base 211. The processing mechanism 20 is connected to the positioning mechanism 10 via the first base 211, enabling the processing mechanism 20 to achieve a wide range of movement and preliminary positioning in the first transverse direction, the longitudinal direction, and the second transverse direction.

[0112] The machining mechanism 20 includes a machining base 21, a spindle assembly 22, and a pressure member 23. The machining base 21 comprises a first base 211, a second base 212, and five branches. As shown in Figures 1 and 7-10, the first base 211 is connected to the base connection portion 142 of the second transverse moving member 14, connecting the machining mechanism 20 to the positioning mechanism 10. This allows the machining mechanism 20 to move over a wide range and achieve preliminary positioning in the first transverse, longitudinal, and second transverse directions along with the positioning mechanism 10.

[0113] The first base 211 is also connected to the first hinges 241 of the five branches. These five first hinges 241 are evenly spaced and equidistant around the circumference of the main shaft assembly 22. The second base 212 is connected to the second hinge 242 of the first branch 24 and the third hinges 251 of the remaining four branches. The second hinge 242 and two third hinges 251 are evenly spaced and equidistant around the circumference of the main shaft assembly 22, located at the bottom of the second base 212. The other two third hinges 251 are located between the second revolving secondary hinge 242 and the two third hinges 251 located at the bottom of the second base 212, and are equidistant above the second base 212. In addition, each of the five branches includes a branch drive 243 and a branch screw 244. The branch drive 243 and the branch screw 244 are threadedly connected to drive the branch screw 244 to axially extend and retract, thereby realizing five degrees of freedom posture adjustment, so that the axial direction of the main shaft 221 is consistent with the actual normal direction of the point to be processed.

[0114] In addition, the processing base 21 also includes a first driving member 213, a second driving member 215, a fourth slide rail 217 and a fourth slider 218. The first driving member 213 drives the first telescopic portion 214 to extend or retract. The first telescopic portion 214 is connected to the first connecting portion 231 arranged on the pressure member 23, so as to drive the pressure member 23 to extend or retract through the first connecting portion 231, thereby enabling the pressure member 23 to contact, press or separate with the component 40. The second driving member 215 drives the second telescopic portion 216 to extend or retract. The second telescopic portion 216 is connected to the second connecting portion 223 arranged on the spindle assembly 22, so as to drive the spindle assembly 22 to extend or retract through the second connecting portion 223, thereby enabling the spindle assembly 22 to perform processing operations on the processing point. Specifically, the first driving member 213 is a cylinder, and the second driving member 215 is an electric push rod. The fourth slider 218 is fixedly connected to the main shaft assembly 22 , so that the main shaft assembly 22 can move along the fourth slide rail 217 through the fourth slider 218 , thereby guiding the telescopic movement of the main shaft assembly 22 .

[0115] As shown in Figures 1, 7-8 and 11-13, the spindle assembly 22 includes a spindle 221, a spindle motor 222 and a second connecting portion 223. The movement of the spindle 221 includes rotation and movement. Specifically, the spindle 221 is located in the middle of the hollow spindle motor 222 and is passed through the pressure member 23. The spindle 221 is close to the axial end of the component 40 for processing operations. Therefore, the spindle 221 can be a tool, a drill bit, etc., or a tool, a drill bit, etc. can be installed at the end close to the component 40 to perform processing operations on the points to be processed on the component 40. The spindle motor 222 drives the spindle 221 to rotate. At the same time, the second connecting portion 223, driven by the second driving member 215, feeds the spindle assembly 22 as a whole. The spindle motor 222 drives the spindle 221 to rotate, cooperating to realize the processing operations such as drilling holes on the points to be processed by the spindle 221.

[0116] As shown in Figures 1, 7-8 and 11-13, the pressure member 23 is provided with a first connecting portion 231 and a distance detecting member 232. The first connecting portion 231 is driven by the first driving member 213 to drive the pressure member 23 to extend or retract, thereby achieving contact or compression between the pressure member 23 and the surface of the component 40, reducing the component 40 during the drilling process.

[0117] The possibility of deformation due to local low stiffness. Four distance detection members 232 are evenly spaced and arranged on the conical portion of the surface of the pressure member 23 facing the component 40, and are used to detect the distance to the point to be processed on the surface of the component 40. Three of them detect the normal direction of the point to be processed, and the fourth distance detection member 232 is used for verification and calibration, which is conducive to improving the accuracy of normal detection, achieving high-quality drilling, and improving the processing efficiency of the component processing system 100. It is worth noting that the spindle assembly 22 and the pressure member 23 can move independently, that is, the three processes of feeding the spindle 221, extending the pressure member 23 and measuring the distance of the rod 244 do not affect each other, thereby ensuring the positioning accuracy of the processing mechanism 20.

[0118] The auxiliary tooling 30 is arranged on one side of the positioning mechanism 10 along the second horizontal direction, as shown in Figures 1 and 14. The auxiliary tooling 30 is used to fix the component 40, and the auxiliary tooling 30 and the positioning mechanism 10 are arranged independently, which can get rid of the limitations of traditional machine tools on the working space and make the installation and processing of the component 40 more convenient.

[0119] As shown in FIG. 15 to FIG. 17 , the control method of the component processing system 100 includes the following steps:

[0120] S1: Installing the component 40 to be processed onto the independently arranged auxiliary tooling 30;

[0121] S2: Control the positioning mechanism 10 to move along the first transverse direction, the longitudinal direction, and the second transverse direction to position the spindle assembly 22 connected thereto to be opposite to the workpiece 40 to be processed;
