Description

Technical Field

[0001] The invention relates to the technical field of precision machining, in particular to a multi-axis polishing machine. Background Art

[0002] High-precision optical components are essential components for many major projects in the aerospace and military defense fields. They have high performance requirements and huge demand, so it is very important to develop precision batch processing equipment and technology. Optical components have extremely high requirements for surface quality and surface shape accuracy during the polishing process. At present, airbag polishing machines can be used for polishing to improve processing efficiency and reduce costs.

[0003] However, conventional polishing machines, such as a non-spherical optical element polishing device and polishing method disclosed in Chinese patent CN102922389B, have the following shortcomings: 1. Due to the limitation of structure layout, the polishing coverage of the airbag head of the traditional polishing machine is only hemispherical; 2. There will be errors in the assembly adjustment and spatial analysis of traditional polishing machines, which will affect the processing accuracy; 3. The airbag tool structure of the traditional polishing machine consists of two rotating axes (tool A axis and tool B axis), in which the airbag head is connected to the end of the tool B axis, and the tool B axis is connected to the end of the tool A axis. When processing high-steep workpieces, due to the long distance between the polishing head and the tool A axis, vibration will occur, which will have a greater impact on the polishing accuracy.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] like Figures 1 to 6 As shown, a multi-axis polishing machine of this embodiment includes a machine tool 1, an X-axis driving mechanism 2, a W-axis driving mechanism 3, a C-axis rotating mechanism 4, a C1-axis rotating mechanism 5 and an airbag tool 6.

[0021] The machine tool 1 comprises a bed 11 , a column 12 and a crossbeam 13 . The column 12 is vertically arranged on the bed 11 , and the crossbeam 13 is horizontally arranged on the top of the column 12 .

[0022] The X-axis driving mechanism 2 is disposed on the bed 11 , and the C-axis rotating mechanism 4 is connected to the X-axis driving mechanism 2 and is controlled by the X-axis driving mechanism 2 to reciprocate along the X-axis direction.

[0023] The C-axis rotating mechanism 4 includes a C-axis turntable 41 , and the C-axis turntable 41 is used to place the workpiece 10 and drive the workpiece 10 to rotate around the Z axis.

[0024] The C1-axis rotation mechanism 5 includes a C1-axis rotation arm 51 and a C1-axis driving device 52. The upper side of the C1-axis rotation arm 51 is provided with a C1 rotation shaft 55 rotatably connected to the crossbeam 13, and the lower side of the C1-axis rotation arm 51 is provided with a C1 lower shaft 54 ​​rotatably connected to the bed 11; and the C1-axis rotation arm 51 is driven by the C1-axis driving device 52 to rotate around the C-axis turntable 41 and the Z-axis.

[0025] The W-axis driving mechanism 3 is disposed in the middle of the C1-axis rotating arm 51 , and the airbag tool 6 is disposed between the W-axis driving mechanism 3 and the C-axis turntable 41 and is controlled by the W-axis driving mechanism 3 to reciprocate along the Z-axis direction.

[0026] The airbag tool 6 includes an airbag tool rotating arm 61, an airbag tool rotating motor 62, a spindle motor 63 and an airbag head 64. One end of the airbag tool rotating arm 61 is provided with an airbag tool rotating shaft 65 which is rotatably connected to the W-axis driving mechanism 3, and the airbag tool rotating shaft 65 is transmission-connected to the airbag tool rotating motor 62. A spindle motor 63 is provided at the other end of the airbag tool rotating arm 61, and the spindle motor 63 is used to drive the airbag head 64 to rotate.

[0027] Thus, the multi-axis polishing machine of this embodiment has a C-axis turntable 41, a C1 axis 55, an airbag tool axis 65 and a spindle motor 63. When working, the multi-rotating axes are linked, and the X-axis drive mechanism 2 and the W-axis drive mechanism 3 are coordinated. Figure 7 , the processing range of the airbag head 64 can cover the entire spherical surface, which is more advantageous for processing workpieces 10 with a length-to-diameter ratio greater than 1, such as conformal head covers.

[0028] Furthermore, the extended lines of the axes of the spindle motor 63, the airbag tool shaft 65 and the C1 shaft 55 of the multi-axis polishing machine of this embodiment can be perpendicular to each other, so that the extended lines of the three axes can intersect at one point to form a virtual point, which is convenient for assembly and adjustment, and is also more convenient for spatial analysis during processing, and has higher polishing accuracy.

[0029] At the same time, the C1-axis rotating arm 51 can rotate around the C-axis turntable 41, and the upper and lower sides are respectively connected to the machine tool 1 through the C1 rotating shaft 55 and the C1 lower shaft 54, which can improve the stability of the multi-axis polishing machine and thereby improve the processing accuracy. Specifically, the top of the C1-axis rotating arm 51 rotates around the Z-axis and the C-axis turntable 41 through the C1 rotating shaft 55, and the bottom is supported by the C1 lower shaft 54 ​​installed on the bed 11, and the airbag tool 6 is located in the middle of the C1-axis rotating arm 51. In this way, compared with the prior art, the distance from the airbag head 64 to the airbag tool rotating shaft 65 can be greatly shortened, so that the rigidity of the airbag tool rotating arm 61 is improved, and the processing is more stable.

[0030] In this embodiment, the lower side of the C1-axis rotating arm 51 is also slidably connected to the C1-axis rotating arm support rail 53 provided on the bed 11; the C1-axis rotating arm support rail 53 is arc-shaped and can be at least half an arc, so that the C1-axis rotating arm 51 can rotate at least 180° around the C-axis turntable 41. This further improves the support performance, improves the stability of the rotation of the C1-axis rotating arm 51, and improves the machining accuracy.

[0031] In this embodiment, the C axis and the C1 axis are rotation axes rotating around the Z axis, and the W axis is an additional axis parallel to the Z axis.

[0032] The multi-axis polishing machine may further include a control system (not shown), which is electrically connected to the X-axis drive mechanism 2, the W-axis drive mechanism 3, the C-axis rotation mechanism 4, the C1-axis rotation mechanism 5 and the airbag tool 6. It is used to uniformly control the operation of each mechanism to achieve efficient and fast processing. The control system and control method can refer to the existing technology.

[0033] like Figure 1 and Figure 3 As shown, in this embodiment, two columns 12 can be erected on the bed 11 with the X-axis drive mechanism 2 spaced apart; the two ends of the crossbeam 13 are respectively connected to the tops of the two columns 12 to form a gantry structure, so as to improve the overall structural stability of the machine tool 1.

[0034] The crossbeam 13 may have a protruding mounting portion 131 in the middle, and the C1 axis driving device 52 is installed below the mounting portion 131. The C1 axis driving device 52 is a motor such as a harmonic reduction motor, and the lower motor shaft of the motor is the C1 rotating shaft 55, so that the C1 rotating shaft 55 can be driven to rotate through the C1 axis driving device 52.

[0035] like Figure 1 The upper and lower ends of the C1-axis rotating arm 51 may be respectively provided with transverse connecting arms 511 , so that the C1-axis rotating arm 51 is roughly “C”-shaped, so as to rotate around the C-axis turntable 41 and remain coaxial with the C-axis turntable 41 .

[0036] Specifically, the end of the upper transverse connecting arm 511 is connected to the C1 rotating shaft 55 to be rotatably connected to the crossbeam 13, and the end of the lower transverse connecting arm 511 is rotatably connected to the C1 lower shaft 54 ​​set on the bed 11; the C1 lower shaft 54 ​​can be installed in the bearing seat 15 set below the C-axis rotating mechanism 4.

[0037] like Figure 1 and Figure 2 In this embodiment, a saddle 14 may be provided on the bed 11, and the X-axis drive mechanism 2 is arranged on the saddle 14. The X-axis drive mechanism 2 includes an X-axis guide rail 21, an X-axis slide plate 22, an X-axis drive motor 23 and an X-axis screw rod 24.

[0038] There can be two X-axis guide rails 21, which are arranged at intervals on the slide saddle 14; the X-axis slide plate 22 is slidably connected between the two X-axis guide rails 21 and is connected to the X-axis screw rod 24, the X-axis drive motor 23 is located behind the bed 11 and is connected to the X-axis screw rod 24; the C-axis turntable 41 is arranged on the X-axis slide plate 22.

[0039] The X-axis drive motor 23 can drive the X-axis screw rod 24 to rotate, thereby driving the X-axis slide plate 22 and the C-axis turntable 41 to reciprocate along the X-axis direction, so that the C-axis turntable 41 can maintain coaxiality with the C1-axis drive device 52 .

[0040] like Figure 1 and Figure 3 As shown, the W-axis driving mechanism 3 of the present embodiment includes a W-axis guide rail 31, a W-axis slide plate 32, a W-axis driving motor 33 and a W-axis screw rod 34; the W-axis guide rail 31 is arranged on the vertical part of the C1-axis rotating arm 51, and the W-axis slide plate 32 is slidably connected to the W-axis guide rail 31 and is connected to the W-axis screw rod 34, and the W-axis driving motor 33 is transmission-connected to the W-axis screw rod 34; the airbag tool rotating shaft 65 of the airbag tool 6 and the C1-axis driving device 52 are arranged on the W-axis slide plate 32.

[0041] Specifically, the C1-axis rotating arm 51 is arranged to rotate around the C-axis turntable 41; and the W-axis guide rails 31 may have two, which are respectively arranged on both sides of the circumference of the C1-axis rotating arm 51; the W-axis slide plate 32 is located radially inside the C1-axis rotating arm 51 and has two sliding parts 321 respectively slidingly connected to the two W-axis guide rails 31, and the sliding parts 321 are provided with hydraulic clamps 322 for sliding positioning with the W-axis guide rails 31. Therefore, by using the two sliding parts 321 of the W-axis slide plate 32 to hold the W-axis guide rail 31 tightly, the stability of the reciprocating sliding of the airbag tool 6 and the W-axis slide plate 32 along the Z axis can be improved to ensure the processing accuracy.

[0042] Furthermore, the middle portion of the C1-axis rotating arm 51 may have a through slot 512 that penetrates radially and extends up and down, and the airbag tool rotating motor 62 may be installed on the W-axis slide plate 32 and be in driving connection with the airbag tool rotating shaft 65; in this embodiment, the airbag tool rotating shaft 65 is the motor shaft of the airbag tool rotating motor 62. The airbag tool rotating motor 62 may also be a harmonic reduction motor or the like.

[0043] The through slot 512 can make way for the airbag tool rotating motor 62, so that the W-axis slide plate 32 can move up and down along the Z-axis with the airbag tool rotating motor 62.

[0044] The W-axis drive motor 33 and the W-axis screw 34 can be arranged on the radially outer side of the C1-axis rotating arm 51 away from the W-axis slide 32, and the W-axis drive motor 33 can be arranged above the C1-axis rotating arm 51. The W-axis drive motor 33 drives the W-axis screw 34 to rotate, and the rotation of the W-axis screw 34 drives the W-axis slide 32 to move up and down along the Z-axis.

[0045] The X-axis driving mechanism 2 and the W-axis driving mechanism 3 in this embodiment adopt a ball screw linear transmission mechanism. Of course, other linear module structures such as a linear motor type linear module can also be adopted.

[0046] To sum up, the multi-axis polishing machine of the present invention, by setting an X-axis drive mechanism 2 and a W-axis drive mechanism 3 on the machine tool 1, utilizing the stable rotation of the C1-axis rotating arm 51, and coordinating the multi-rotating axes of the C-axis turntable 41, the C1 rotating shaft 55, the airbag tool rotating shaft 65 and the spindle motor 63, can achieve large-scale, high-precision spherical or aspherical processing and polishing of the workpiece 10 under the control of the control system, and has better production efficiency and processing advantages.
