Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled machine tools, and in particular to a spindle assembly detection device for numerically controlled machine tools. Background Art

[0002] With the rapid development of industries such as automobiles, national defense, aviation, and aerospace, as well as the application of new materials such as aluminum alloys, the requirements for high-speed CNC machine tool processing are getting higher and higher. At present, CNC machine tools are suitable for processing parts with special-shaped structures, complex structures, large sizes, high precision requirements, and parts that need frequent modifications; the requirements for precision of CNC machine tools are no longer limited to static geometric precision. The motion accuracy of machine tools and the monitoring and compensation of vibrations are gaining more and more attention. In principle, the structure of modern precision CNC machine tools and traditional machine tools has not changed much. The main difference is the improvement of guide rail processing and installation technology and the improvement of spindle system processing and installation accuracy.

[0003] The patent document with patent number CN113618370A discloses a spindle assembly detection device for a CNC machine tool, including a support base, a through hole is opened in the center of the support base, and a spindle clamping mechanism is arranged in the central through hole of the support base, and a spindle detection mechanism is arranged on the upper end surface of the support base; the spindle detection mechanism includes a support plate, and the support plate is vertically fixed above the support base. The overall length of the support base arranged in the present invention can be adjusted according to the use space. At the same time, the device is provided with a spindle clamping mechanism, and the first spindle clamping plate and the second spindle clamping plate in the spindle clamping mechanism can be adjusted, so that spindles of different widths can be restricted. At the same time, the support base of the device can be connected together by connecting threaded rods, so that multiple devices can be connected together, which is convenient for detecting spindles of different lengths and increases the scope of application of the device.

[0004] However, in the actual assembly inspection process, the inventors found that the existing inspection requires assembly inspection between the slide rails on both sides and the main shaft. The existing assembly inspection process usually relies on manual inspection, which requires a high level of adjustment from the operator. The operator's training cycle is long and the cost is high. Manual operation reduces the speed of adjusting the slide rails and the main shaft, affecting the assembly inspection efficiency. At the same time, the inspection accuracy varies due to different operating methods. This human factor often leads to fluctuations in assembly accuracy, which may in turn cause errors in the assembly accuracy of the guide rails and the main shaft, affecting the overall performance of the machine tool.

[0032] The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings.

[0033] Embodiment 1 like Figure 1-Figure 3 As shown, a spindle assembly detection device for a CNC machine tool comprises: Disassemble the housing 1 disposed on the machine tool 7, the storage mechanism 2 disposed on the housing 1 and used to store the position information of the first guide rail 71 on the machine tool 7, the first support mechanism 3 disposed on the housing 1 and used to support the second guide rail 72 on the machine tool 7, the second support mechanism 4 disposed on the housing 1 and used to support the spindle mounting seat 74 on the machine tool 7, disassemble the detection mechanism 5 disposed on the slider 73 of the first guide rail 71 and the second guide rail 72 and used to detect the position information of the storage mechanism 2 and the second support mechanism 4, and the adjustment mechanism 6 disposed in the housing 1 and used to adjust the positions of the storage mechanism 2, the first support mechanism 3 and the second support mechanism 4; The adjusting mechanism 6 includes a mobile frame 61 movably arranged in the outer shell 1, a connecting component 62 arranged on the mobile frame 61 and used to connect the storage mechanism 2, the first supporting mechanism 3 and the second supporting mechanism 4 as the mobile frame 61 moves, and an adjusting component 63 arranged on the mobile frame 61 and cooperating with the connecting component 62 to adjust the storage mechanism 2, the first supporting mechanism 3 and the second supporting mechanism 4.

[0034] In this embodiment, a detection mechanism 5 is provided to cooperate with an adjustment mechanism 6 to automatically detect and adjust the position information between the storage mechanism 2, the second guide rail 72 on the first support mechanism 3, and the spindle mounting seat 74 on the second support mechanism 4 and the first guide rail 71 to quickly match, thereby avoiding errors in manual operation; at the same time, the adjustment component 63 cooperates with the connecting component 62 to connect with the storage mechanism 2, the first support mechanism 3 and the second support mechanism 4 in sequence during the movement of the mobile frame 61 for adjustment. The structure is compact, so that the space occupied by the adjustment mechanism 6 is reduced to adapt to the machine tool 7 which has limited space.

[0035] In detail, when in use, firstly, the first guide rail 71 is installed on the machine tool 7 as an assembly reference and the detection mechanism 5 is installed on the first guide rail 71, the connecting component 62 moves with the moving frame 61 and is connected to the storage mechanism 2, and the adjusting component 63 is able to adjust the position information of the storage mechanism 2 until the detection mechanism 5 detects that the position information between the storage mechanism 2 and the first guide rail 71 matches; then the first supporting mechanism 3 supports the second guide rail 72 and the detection mechanism 5 is installed on the second guide rail 72, the connecting component 62 moves with the moving frame 61 and is connected to the first supporting mechanism 3, and the adjusting component 63 is able to adjust the second supporting mechanism 4 until the detection mechanism 5 detects that the position information of the second guide rail 72 matches that of the storage mechanism 2, and then the second guide rail 72 is assembled on the machine tool 7; finally, the second supporting mechanism 4 supports the spindle mounting seat 74, the connecting component 62 moves with the movable frame 61 and is connected to the second supporting mechanism 4, and the adjusting component 63 is able to adjust the position of the second supporting mechanism 4 until the detection mechanism 5 detects that the position information of the spindle mounting seat 74 matches that of the second guide rail 72, and then the spindle mounting seat 74 is assembled on the machine tool 7; the entire detection and assembly process has a high degree of automation, reduces costs, is efficient, and avoids errors caused by human interference.

[0036] It should be noted that the number of spindle assembly detection devices used for CNC machine tools is two, and the spindle assembly detection devices of the two CNC machine tools are respectively arranged at the two ends of the machine tool 7, so as to respectively perform adjustment detection on the two ends of the second guide rail 72 and respectively perform adjustment detection on the two spindle mounting seats 74 at the two ends of the fixed spindle; in addition, the outer shell 1 is plugged into or connected to the machine tool 7 by bolts to realize the detachable connection between the two.

[0037] Further, if Figure 3-Figure 4 As shown, the connecting assembly 62 includes a spur gear 621 rotatably disposed on the moving frame 61 and a bevel gear bar 622 disposed on the side of the spur gear 621 .

[0038] In this embodiment, by providing a spur gear 621 and a helical gear bar 622 , the movable frame 61 is meshedly connected with the storage mechanism 2 , the first supporting mechanism 3 and the second supporting mechanism 4 during the movement process.

[0039] It should be noted that bevel gear bars 622 are provided on both sides of the spur gear 621, and the bevel gears on both sides are respectively used to connect and drive the storage mechanism 2 and the second support mechanism 4, so that sufficient space can be provided on both sides of the spur gear 621 for installing the storage mechanism 2 and the second support mechanism 4, so that the space is reasonably utilized, reducing the difficulty of installation of the structure and the possibility of interference.

[0040] Further, if Figure 1-Figure 3 as well as Figure 6 As shown, the storage mechanism 2 includes a square bar 21 for storing position information of the first guide rail 71, a support seat 22 that is movably disposed on the outer shell 1 and rotatably disposed and is used to support one end of the square bar 21, a first rack 23 that is movably disposed on the outer shell 1 and is engaged with the spur gear 621 and is used to force the support seat 22 to move, a first locking assembly 24 that is disposed in the outer shell 1 and is used to limit the upward and downward movement of the support seat 22, and a rotating assembly 25 that is disposed in the outer shell 1 and is engaged with the bevel gear bar 622 and is used to force the support seat 22 to rotate.

[0041] In this embodiment, the first rack 23 and the rotating assembly 25 are arranged to mesh with the spur gear 621 and the bevel gear 622 respectively, so as to adjust the position of the support seat 22 so that the upper surface and the side surface of the square bar 21 are parallel to the upper surface and the side surface of the first guide rail 71 respectively. The surface of the square bar 21 is flat and convenient for measurement to store the position information of the first guide rail 71. At the same time, the first locking assembly 24 is used to prevent the support seat 22 from moving after the first rack 23 is separated from the spur gear 621, so the adjustment effect is good.

[0042] In detail, during adjustment, the moving frame 61 is first moved until the spur gear 621 is engaged with the first rack 23; then the first rack 23 pushes the support seat 22 to move upward to lift one end of the square bar 21 until the square bar 21 is parallel to the upper surface of the first guide rail 71, and the first locking assembly 24 limits the up and down movement of the support seat 22; then the moving frame 61 is moved to separate the spur gear 621 from the first rack 23, and the spur gear 621 is rotated to reset to the position of the rotating assembly 25, so that the bevel gear bar 622 is engaged with the rotating assembly 25; finally, the rotating assembly 25 forces the support seat 22 to rotate and drives the square bar 21 to swing left and right, until the square bar 21 is parallel to the side of the first slide rail 52, and the square bar 21 is able to store the position information of the first guide rail 71.

[0043] It should be noted that when storing the information of the first guide rail 71, one end of the square bar 21 is positioned and supported by the support seat 22 at one end of the machine tool 7, and the other end of the square bar 21 is supported on the support seat 22 through the sliding of the other end of the machine tool 7, so that the square bar 21 can swing during the adjustment process. At the same time, the square bar 21 can be solid steel with a large enough weight and a large enough friction force to prevent a small external force from easily forcing the swing. In addition, the storage mechanism 2 also includes a reset spring 26 arranged on the outer shell 1 and used to force the first rack 23 to move downward, so as to facilitate the quick and accurate reset of the first rack 23, so that the first rack 23 can be quickly and accurately connected to the spur gear 621 when it is used next time.

[0044] Further, if Figure 6 as well as Figure 8-Figure 9 As shown, the first locking assembly 24 includes a support plate 241 rotatably disposed below the support seat 22 and movably disposed up and down on the outer shell 1, a first locking plate 242 movably disposed up and down below the support plate 241 and used to limit the downward movement of the support plate 241, and a first elastic member 243 disposed in the outer shell 1 and used to force the support plate 241 to fit against the locking plate.

[0045] In this embodiment, the first locking plate 242 is provided to limit the support seat 22 from moving downward with the support plate 241, and the first elastic member 243 is used to force the support plate 241 to fit together with the first locking plate 242, so that the support plate 241 is accurately limited in position, and at the same time, the support seat 22 is forced to reset with the support plate 241, which is convenient for the next use.

[0046] In detail, when in use, the first rack 23 pushes the support plate 241 to move upward, the first elastic member 243 is deformed and provides a force for the support plate 241 to move downward, and then, under the force provided by the first elastic member 243 for the support plate 241 to move downward, the first locking plate 242 is prevented from moving upward and easily pushing the support plate 241 to move upward, and the first locking plate 242 is able to fit against the lower surface of the support plate 241 to complete the limit locking, and when the first locking plate 242 moves downward, the first elastic member 243 resumes its deformation, forcing the support seat 22 to move downward and reset with the support plate 241.

[0047] It should be noted that the support plate 241 is located in the middle of the support seat 22, and the first rack 23 is used to push the middle of the support plate 241, so as to improve the smoothness of the movement of the device, facilitate adjustment, and improve the accuracy of adjustment.

[0048] Further, if Figure 6-Figure 8 As shown, the rotating assembly 25 includes a first transmission gear 251 disposed on the support base 22, a second transmission gear 252 rotatably disposed on the housing 1 and meshed with the first transmission gear 251, and a first bevel gear 253 disposed on the second transmission gear 252 and meshed with the bevel gear bar 622 and used to force the second transmission gear 252 to rotate.

[0049] In this embodiment, by setting the first bevel gear 253 to engage with the bevel gear bar 622, the second transmission gear 252 and the first transmission gear 251 can be driven to rotate, thereby driving the support base 22 to rotate; in addition, the transmission of the first transmission gear 251 and the second transmission gear 252 allows the first transmission gear 251 to be installed at the center position of the support base 22, thereby improving the smoothness of the rotation of the device, and the adjustment angle is easy to control, thereby improving the accuracy of the adjustment.

[0050] Further, if Figure 1-Figure 3 as well as Figure 6 As shown, the first support mechanism 3 includes a mounting frame 31 arranged on the first rack 23, a support frame 32 slidably arranged on the mounting frame 31 along the left and right directions and extending to the outside of the housing 1, a support rod 33 rotatably arranged on the support frame 32 and used to be inserted into the connecting hole 721 on one end of the second guide rail 72, a second rack 34 arranged on the support frame 32 and engaged with the spur gear 621 and used to force the support frame 32 to move, and a second locking assembly 35 arranged on the mounting frame 31 and used to limit the left and right movement of the support frame 32.

[0051] In this embodiment, the mounting frame 31 is provided so that the first rack 23 and the second rack 34 can adjust the up and down and left and right positions of the support frame 32, so that the upper surface and the side surface of the second guide rail 72 are respectively parallel to the upper surface and the side surface of the first guide rail 71, and the second locking assembly 35 is used to prevent the support frame 32 from moving left and right after the second rack 34 is separated from the spur gear 621, thereby achieving a good adjustment effect.

[0052] In detail, during adjustment, the movable frame 61 is first moved until the spur gear 621 is meshed with the second rack 34; then the support frame 32 moves left and right with the second rack 34 to adjust the position of the side of the second guide rail 72 until the second guide rail 72 is parallel to the side of the square bar 21, and the second locking assembly 35 limits the left and right movement of the support frame 32; then the movable frame 61 is moved to separate the spur gear 621 from the second rack 34 and then the spur gear 621 is meshed with the first rack 23; finally, the support frame 32 moves up and down with the first rack 23 through the mounting frame 31 to adjust the position of the upper surface of the second guide rail 72 until the second guide rail 72 is parallel to the upper surface of the square bar 21, and then the second guide rail 72 is installed on the machine tool 7.

[0053] It should be noted that during the process of adjusting the position, the support rod 33 at one end of the machine tool 7 is rotatably connected to the support frame 32, and the support rod 33 at the other end of the machine tool 7 is fixed to the support frame 32. The two ends of the second guide rail 72 are rotatably connected to the two support rods 33 through two connecting holes 721, so that the support rod 33 can swing during adjustment.

[0054] Further, if Figure 8 as well as Figure 10-11 As shown, the second locking assembly 35 includes a second locking plate 351 movably disposed on the mounting frame 31 and used to limit the support frame 32 from moving into the housing 1 , and a second elastic member 352 disposed on the mounting frame 31 and used to force the support frame 32 to move into the housing 1 .

[0055] In this embodiment, the second locking plate 351 is provided to limit the movement of the support frame 32 in the housing 1, and the first elastic member 243 is used to force the support frame 32 to fit the second locking plate 351, so that the support frame 32 is accurately limited in position and the support frame 32 is forced to reset for the next use.

[0056] It should be noted that the first elastic member 243, the second elastic member 352 and the return spring 26 are coil springs, leaf springs, etc., and both the first elastic member 243 and the second elastic member 352 and the return spring 26 are conventional techniques and will not be described in detail herein.

[0057] Further, if Figure 2-Figure 3 as well as Fig.12As shown, the second supporting mechanism 4 includes a rotating frame 41 rotatably arranged on the housing 1 along the left-right direction, a second bevel gear 42 arranged on the rotating frame 41 and meshed with the bevel gear bar 622 and used to drive the rotating frame 41 to rotate, a support column 43 rotatably arranged on the rotating frame 41 along the up-down direction and inserted into the shaft hole 741 on the spindle mounting seat 74, a third bevel gear 44 arranged on the support column 43 and meshed with the bevel gear bar 622 and used to drive the support column 43 to rotate, a limit assembly 45 arranged on the rotating frame 41 and used to limit the rotation of the support column 43, and a shaft 46 inserted into the shaft hole 741 and used to simulate the spindle.

[0058] In this embodiment, by setting the third bevel gear 44 and the second bevel gear 42 to mesh with the bevel gear bar 622 in sequence, the left and right and up and down positions of the support column 43 are adjusted in sequence, and then the position of the main shaft mounting seat 74 is adjusted, so that the position of the shaft rod 46 matches the position of the second guide rail 72, and at the same time, the limit assembly 45 is used to prevent the support column 43 from rotating after the third bevel gear 44 is separated from the spur gear 621 and the bevel gear bar 622. The adjustment effect is good, the surface of the shaft rod 46 is flat and easy to measure, and the two shaft rods 46 inserted in the two main shaft mounting seats 74 can be adjusted separately.

[0059] In detail, during adjustment, first rotate the spur gear 621 to align the bevel gear bar 622 with the third bevel gear 44, and then move the movable frame 61 to make the bevel gear bar 622 mesh with the third bevel gear 44; then the third bevel gear 44 is able to drive the support column 43 to rotate left and right until the axis of the shaft rod 46 is parallel to the side of the second guide rail 72, and the limit assembly 45 limits the rotation of the support column 43; then move the movable frame 61 to separate the bevel gear bar 622 from the third bevel gear 44, and rotate the spur gear 621 to align the bevel gear bar 622 with the second bevel gear 42, and then move the movable frame 61 to make the bevel gear bar 622 mesh with the second bevel gear 42; finally, the second bevel gear 42 is able to drive the support column 43 to rotate up and down with the rotating frame 41 until the axis of the shaft rod 46 is parallel to the upper surface of the second guide rail 72. Similarly, after measuring that the axes of the two shaft rods 46 are colinear and parallel to the sliding direction of the slider 73, the spindle mounting seat 74 can be assembled on the machine tool 7 for assembling the spindle.

[0060] It should be noted that the rotating frame 41 automatically rotates downward to achieve reset under the action of gravity of the support column 43, the spindle mounting seat 74 and the shaft 46, so that the third bevel gear 44 and the second bevel gear 42 can be engaged with the bevel gear bar 622; in addition, please do not limit the specific structure of the limit assembly 45 itself, and a certain limit can be achieved by a high-precision damper, or by an extrusion piece cooperating with the rotating frame 41 to clamp the support column 43 for limit. Both methods are existing technologies and will not be described in detail here.

[0061] Further, if Figure 4-Figure 5 As shown, the adjustment assembly 63 includes a plurality of gear sets 631 rotatably disposed on the moving frame 61 and meshing with each other in sequence, and a driving gear 634 disposed on the moving frame 61 and used to drive the gear set 634 to rotate, and the first two gear sets 631 are respectively meshed with the spur gear 621 and the driving gear 634; The gear set 631 includes a first gear 632 rotatably disposed on the moving frame 61 and a second gear 633 disposed on one side of the first gear 632 and having a smaller diameter than the first gear 632 set, and the first gear 632 of the previous gear set 631 is meshed with the second gear 633 of the subsequent gear set 631 .

[0062] In this embodiment, a plurality of gear sets 631 are rotationally connected by setting a first gear 632 of different diameters to mesh with the second gear 633, so that the rotation angles of the first two gear sets 631 differ by a certain multiple, and then when the last gear set 631 is driven by the driving gear 634 to rotate a certain angle, the first gear set 631 is able to drive the spur gear 621 to rotate a very small angle, and by changing the diameter ratio of the first gear 632 and the second gear 633 and the number of gear sets 631, the rotation angle of the spur gear 621 can be 1 / 1000 of the rotation angle of the driving gear 634, or even smaller, thereby achieving high-precision adjustment and avoiding large errors.

[0063] It should be noted that the driving gear 634 is driven by a stepper motor to achieve small and precise adjustment; in addition, the gear set 631 meshing with the spur gear 621 is also driven by a stepper motor, which is convenient for quickly driving the spur gear 621 to rotate, thereby quickly adjusting the position of the bevel gear bar 622, further improving the detection efficiency.

[0064] Further, if Figure 1-Figure 2 as well as Fig.13 As shown, the detection mechanism 5 includes a base 51 inserted into the mounting groove 731 on the slider 73, a first slide rail 52 arranged on the base 51 along a direction perpendicular to the sliding direction of the slider 73, a second slide rail 53 slidably arranged on the first slide rail 52, a support arm 54 slidably arranged on the second slide rail 53 along the up and down directions and capable of flexion and extension, and a measuring gauge 55 arranged on the support arm 54.

[0065] In this embodiment, the measuring gauge 55 is arranged to cooperate with the flexion and extension of the support arm 54 to measure the positional relationship among the first slide rail 52, the square bar 21 and the second slide rail 53 during the sliding process of the slider 73. At the same time, with the assistance of the first slide rail 52 and the second slide rail 53, the measuring gauge 55 moves up and down or left and right with the support arm 54, and then the positional relationship between the shaft 46 and the second slide rail 53 is measured.

[0066] In detail, when measuring the surface of the square bar 21, the support arm 54 is adjusted so that the measuring gauge 55 abuts against the upper surface or side surface of the square bar 21, and then the sliding slider 73 is used to measure whether the upper surface and lower surface between the square bar 21 and the first slide rail 52 and the second slide rail 53 are parallel.

[0067] When measuring the shaft rod 46, adjust the support arm 54 so that the measuring gauge 55 is located on the side of the shaft rod 46, and slide the support arm 54 up and down to measure the highest point on the side of one end of the shaft rod 46; then move the slider 73 to the other end of the shaft rod 46, and slide the support arm 54 up and down to measure the highest point on the side of the other end of the shaft rod 46. The two points are connected in a straight line to determine whether the axis of the shaft rod 46 is parallel to the side of the second guide rail 72; then adjust the support arm 54 so that the measuring gauge 55 is located above the shaft rod 46, and slide the support arm 54 left and right to measure the highest point above one end of the shaft rod 46; finally, move the slider 73 to the other end of the shaft rod 46, and slide the support arm 54 left and right to measure the highest point above the other end of the shaft rod 46. The two points are connected in a straight line to determine whether the axis of the shaft rod 46 is parallel to the upper surface of the second guide rail 72, and then measure whether the axis of the shaft rod 46 is parallel to the sliding direction of the slider 73.

[0068] It should be noted that the measuring gauge 55 may be a micrometer, and the support arm 54 that can be flexed and extended is similar to the support frame 32 of the surgical lamp. Therefore, the measuring gauge 55 and the support arm 54 themselves and the installation method are all existing technologies and will not be described in detail here.
