Description

Technical Field

[0001] The present application relates to the field of grinding technology, and in particular to a grinding machine headstock and a grinding machine equipped with the grinding machine headstock. Background Art

[0002] When processing crystal materials, the crystal rod needs to be cut into multiple cylindrical blocks, and then the blocks are ground to form the wafers required for subsequent production. When grinding the blocks, the crystal orientation needs to be measured, and then the crystal grinding is performed based on the results of the crystal orientation measurement. Crystal grinding includes grinding from the end face of the crystal and grinding from the circumference of the crystal.

[0003] In the related art, crystal orientation determination (orientation for short), end face grinding and circumferential surface grinding are all performed separately, and each operation requires the crystal to be repositioned and fixed, etc. This results in complicated crystal processing procedures, which is prone to cumulative errors, not only low precision, but also low overall processing efficiency. Utility Model Content

[0004] Based on this, it is necessary to provide a grinding machine headstock that can not only meet the angle adjustment during the orientation process, but also can be used for end face grinding and circumferential surface grinding. It can meet the orientation and grinding operations without replacing different equipment, thereby improving the processing accuracy and efficiency.

[0005] A grinding machine headstock comprises an integrated seat, a clamping jaw assembly and a supporting assembly; the clamping jaw assembly is connected to the integrated seat and has a first axis, the clamping jaw assembly comprises a plurality of clamping arms arranged at intervals around the first axis, each of the clamping arms jointly defines a clamping space; the supporting assembly is connected to the integrated seat, the supporting assembly comprises a supporting plate and at least two adjusting structures connected to the supporting plate, the supporting plate can be accommodated in the clamping space, at least two of the adjusting structures are arranged at intervals around the first axis; wherein each of the adjusting structures has an actuating shaft that reciprocates along the first axis, and each of the adjusting structures is connected to the supporting plate via its corresponding actuating shaft for driving the supporting plate to swing.

[0006] It can be understood that the support plate mainly plays the role of supporting the crystal, which is equivalent to the fixed reference of the crystal. Since the actuating shafts in each adjustment structure can move independently, the support plate is caused to swing to adjust the position of the support plate. In this way, it is equivalent to changing the fixed reference plane of the crystal, thereby satisfying the angle adjustment during the orientation process, which is suitable for crystal orientation. At the same time, the setting of the clamping jaw assembly can be clamped on the circumferential surface of the crystal. At this time, the support plate can be used as a clamping limiter for the crystal relative to the clamping jaw assembly, which not only improves the fixing stability, but also ensures that the end of the crystal away from the support plate can protrude from the clamping jaw assembly for end face grinding. Moreover, the setting of the support plate can also cooperate with the tailstock of the grinder to clamp the crystal from the first axis to achieve circumferential surface grinding. In this way, there is no need to set different adjustment structures specifically for different orientations, which simplifies the structure of the grinder; and the grinder headstock can be fixed not only from the crystal thickness direction, but also from the crystal circumferential surface, to achieve end face grinding and circumferential surface grinding, without the need to replace different grinders, reducing the cumulative error when replacing the grinder, thereby improving the processing accuracy and processing efficiency.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0027] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first feature is directly in contact with the second feature, or the first feature and the second feature are indirectly in contact through an intermediate medium.

[0028] Unless otherwise defined, all technical and scientific terms used in the specification of this application have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in the specification of this application includes any and all combinations of one or more related listed items.

[0029] See also Figures 1 to 4Another embodiment of the present application provides a grinding machine headstock, including an integrated seat 50 and a clamping assembly 10 and a support assembly 20 connected to the integrated seat 50. The clamping assembly 10 has a first axis. The clamping assembly 10 includes a plurality of clamping arms 11 arranged at intervals around the first axis, and each clamping arm 11 jointly defines a clamping space. The support assembly 20 includes a support plate 21 and at least two adjustment structures 22 connected to the support plate 21, the support plate 21 is accommodated in the clamping space, and the at least two adjustment structures 22 are arranged at intervals around the first axis. Each adjustment structure 22 has an actuating shaft 221 that reciprocates along the first axis, and each adjustment structure 22 is connected to the support plate 21 through its corresponding actuating shaft 221, for driving the support plate 21 to swing.

[0030] It should be noted that the first axis direction is the X-axis direction, which can be referred to as the first axial direction or the X-axis direction. The thickness direction of the crystal is the same as the first axial direction.

[0031] Specifically, the integrated seat 50 is set to meet the support and integrated assembly of the support assembly 20 and the clamping jaw assembly 10. The support plate 21 mainly plays the role of supporting the crystal, which is equivalent to the fixed reference of the crystal. Since the actuating shaft 221 in each adjustment structure 22 can move independently, the support plate 21 is prompted to swing to adjust the pitch angle of the support plate 21. In this way, it is equivalent to changing the fixed reference plane of the crystal, thereby meeting the angle adjustment during the orientation process, which is suitable for crystal orientation. At the same time, the support plate 21 can also cooperate with the tailstock of the grinder to clamp the crystal from the first axis to achieve circumferential surface grinding. Moreover, the clamping arms 11 of the clamping jaw assembly 10 can be clamped on the circumferential surface of the crystal. Since the support plate 21 can be accommodated in the clamping space, the support plate 21 can be used as a clamping limiter for the crystal relative to the clamping jaw assembly 10, which not only improves the fixing stability, but also ensures that the end of the crystal away from the support plate 21 can protrude from the clamping jaw assembly 10 for end face grinding.

[0032] Such a setting has a simple structure and is easy to operate. There is no need to set up different adjustment structures specifically for orientation, which simplifies the structure of the grinding machine. Moreover, the grinding machine headstock provided in this embodiment can also be used to fix the crystal during grinding. It can not only be fixed in the direction of the crystal thickness, but also in the circumferential surface of the crystal, which satisfies both end face grinding and circumferential surface grinding. There is no need to replace different grinders, which reduces the cumulative error when replacing the grinder, thereby improving the processing accuracy and processing efficiency.

[0033] In another optional embodiment, the support plate 21 is provided with a plurality of adsorption holes arranged at intervals to fix the crystal by adsorption. Compared with the use of wax to fix the crystal in the related art, the grinding machine headstock provided in this embodiment is free from the wax sticking and dewaxing links, which greatly shortens the processing time; and such a setting can further improve the fixing effect of the crystal. When the support plate 21 cooperates with the pressure head on the tailstock of the grinder to fix the crystal, the adsorption effect of the support plate 21 on the crystal can reduce the radial movement of the crystal during crystal grinding and improve stability. When the clamping arms 11 in the jaw assembly 10 are clamped on the circumferential surface of the crystal, the adsorption effect of the support plate 21 can reduce the risk of the crystal falling when the jaw assembly 10 is loosened.

[0034] Please continue reading Figures 1 to 4 In an optional embodiment, the support assembly 20 can reciprocate along the first axial direction relative to the clamping jaw assembly 10. In this way, the support plate 21 can be moved out of the clamping space, or moved into the clamping space. When the support plate 21 is accommodated in the clamping space, it can cooperate with the clamping jaw assembly 10 to support one end face of the crystal along the first axial direction, so that the other end face of the crystal protrudes from the clamping jaw assembly 10, which can be suitable for end face grinding. When the support plate 21 moves along the first axial direction toward the side close to the tailstock of the grinder to move out of the clamping space, the support plate 21 can cooperate with the tailstock of the grinder to fix the two ends of the crystal, which is suitable for circumferential surface rolling.

[0035] Please continue reading Figures 1 to 4 Exemplarily, the grinding machine headstock further includes a rotary drive assembly 30 and a linear drive assembly 40, both of which are connected to the integrated seat 50. The rotary drive assembly 30 includes an assembly shell 31 and a power shaft 32, the assembly shell 31 has an assembly cavity 3101, the power shaft 32 is installed in the assembly cavity 3101, the assembly shell 31 is connected to the jaw assembly 10, the power shaft 32 is connected to the support assembly 20, and the power shaft 32 is also connected to the linear drive assembly 40. In actual use, the power shaft 32 can drive the assembly shell 31 to rotate around the first axis to drive the jaw assembly 10 and the support assembly 20 to rotate synchronously; and the power shaft 32 can drive the support assembly 20 to move along the first axial direction under the action of the linear drive assembly 40.

[0036] It can be understood that, by utilizing the setting of the rotary drive assembly 30, the rotation of the support assembly 20 and the jaw assembly 10 during use can be satisfied, thereby driving the crystal to rotate synchronously, which not only satisfies the angle adjustment of the crystal relative to other structures, but also can be used to improve efficiency during grinding. Specifically, the power shaft 32 is connected to the support assembly 20 to drive the support assembly 20 to rotate; and the assembly shell 31 is connected to the jaw assembly 10 to drive the jaw assembly 10 to rotate under the action of the power shaft 32. At the same time, the power shaft 32 also has movement along the first axial direction relative to the assembly shell 31 to satisfy the movement of the support assembly 20 relative to the jaw assembly 10 along the first axial direction. Such a setting is equivalent to the separate setting of the jaw assembly 10 and the support assembly 20 to avoid interference between the two and affect the linear movement of the support assembly 20.

[0037] The rotation of the power shaft 32 may be driven by a motor.

[0038] Furthermore, the linear drive assembly 40 can be a structure that can realize linear drive, such as a cylinder, an oil cylinder, an electric push rod, etc. For example, the linear drive assembly 40 is an oil cylinder, including a first cylinder body 41 and a first piston rod 42 slidably connected to the first cylinder body 41, and the first piston rod 42 is connected to the power shaft 32.

[0039] The end of the power shaft 32 away from the support assembly 20 along the first axial direction may be connected to the seat body, and a bearing may be installed between the seat body and the power shaft 32. At the same time, the side of the seat body away from the power shaft 32 may be connected to the first piston rod 42 by a spherical or hemispherical floating head. The power shaft 32 rotates around the first axis relative to the seat body, the seat body does not rotate, and the first piston rod 42 drives the power shaft 32 to move along the first axial direction through the seat body.

[0040] In an optional embodiment, one of the power shaft 32 and the assembly housing 31 is provided with a guide groove, and the other is provided with a guide protrusion, and the guide protrusion is plugged into the guide groove. The guide protrusion can move along the first axial direction in the guide groove, and is used to guide the power shaft 32 to move along the first axial direction, that is, it plays a guiding role in the linear motion of the power shaft 32; and the side wall of the guide protrusion along the circumference of the power shaft 32 can abut against the groove wall of the guide groove along the circumference of the power shaft 32, so that when the power shaft 32 rotates, the assembly housing 31 is driven to rotate synchronously, and the relative rotation between the power shaft 32 and the assembly housing 31 is limited, thereby improving stability. Among them, the side wall of the guide protrusion along the circumference of the power shaft 32 and the groove wall of the guide groove along the circumference of the power shaft 32 can be gap-fitted, so as to reduce the wear of the guide protrusion relative to the groove wall when the guide protrusion moves along the first axial direction.

[0041] Since the power shaft 32 needs to move along the first axial direction relative to the assembly housing 31, the power shaft 32 and the assembly housing 31 need to be separately provided to ensure their independent movement; and the power shaft 32 also needs to drive the assembly housing 31 to rotate around the first axis, so a structure for transmitting the rotation effect needs to be provided between the power shaft 32 and the assembly housing 31. Therefore, the plug-in cooperation of the guide protrusion and the guide groove not only satisfies the torque transmission of the power shaft 32 to the assembly housing 31, but also ensures that the linear movement of the power shaft 32 will not be interfered by the assembly housing 31, and also plays a guiding role.

[0042] In some specific embodiments, the guide protrusion is provided on the power shaft 32 and protrudes outward in the radial direction of the power shaft 32. The guide groove is provided on the inner side wall of the assembly housing 31 and is recessed outward in the radial direction of the power shaft 32 from the inner side wall. Alternatively, the guide protrusion may be provided on the assembly housing 31 and protrudes inward in the radial direction of the power shaft 32, and the guide groove may be provided on the outer side wall of the power shaft 32 and is recessed inward in the radial direction of the power shaft 32 from the outer side wall.

[0043] like Figure 3 and Figure 5 As shown, further, since the support plate 21 is connected to the power shaft 32, the power shaft 32 can be set as a hollow shaft, so that the air pipe used for adsorption of the support plate 21 can be installed in the hollow.

[0044] See also Figures 3 to 6 Furthermore, the rotation drive assembly 30 further includes a connecting shaft 33, which is connected between the power shaft 32 and the support plate 21. By setting the connecting shaft 33, the installation length of the support plate 21 relative to the power shaft 32 is increased, so as to reserve more sufficient space for installing each adjustment structure 22, thereby improving the stability and convenience of adjusting the pitch angle of the support plate 21.

[0045] Please continue reading Figures 3 to 6 Exemplarily, the support assembly 20 further includes a support seat 23, the support plate 21 is movably connected to the support seat 23, and the side of the support seat 23 away from the support plate 21 along the first axial direction is connected to the power shaft 32. It is worth noting that when the rotary drive assembly 30 includes a connecting shaft 33, the side of the support seat 23 away from the support plate 21 is connected to an end of the connecting shaft 33 away from the power shaft 32. The support plate 21 can rotate relative to the support seat 23 under the action of each adjustment structure 22 to change the posture of the support plate 21 relative to the support seat 23.

[0046] The posture mentioned here refers to the posture of the support plate 21 relative to the support seat 23. For example, the support plate 21 can be parallel to the support seat 23; or, the support plate 21 can be inclined relative to the support seat 23, for example, from top to bottom, the distance between the support plate 21 and the support seat 23 gradually increases; or, from top to bottom, the distance between the support plate 21 and the support seat 23 gradually decreases; or, Figure 1 In the Y-axis direction, the distance between the support plate 21 and the support seat 23 gradually increases or decreases from the front to the back. This is just an example, and the specific posture change is also related to the installation position and number of each adjustment structure 22.

[0047] In some specific embodiments, two adjustment structures 22 are provided and are arranged 180 degrees apart. For example, the two adjustment structures 22 are arranged opposite to each other and spaced apart in the vertical direction (i.e., the Z-axis direction). When the actuating shaft 221 of one of the adjustment structures 22 moves toward the support plate 21, the actuating shaft 221 of the other adjustment structure 22 can move toward the power shaft 32 to adjust the pitch angle of the support plate 21.

[0048] See also Figure 4 and Figure 6 In an optional embodiment, one of the support seat 23 and the support plate 21 is configured with a spherical groove 201, and the other is configured with a spherical protrusion 202, the spherical protrusion 202 is accommodated in the spherical groove 201, and the spherical protrusion 202 can rotate in the spherical groove 201. In other words, the spherical groove 201 and the spherical protrusion 202 are used to improve the movement flexibility of the support plate 21 relative to the support seat 23; and the surface contact method is used to ensure the connection reliability of the two. Among them, the support seat 23 is configured with a spherical groove 201, and the side of the support plate 21 facing the power shaft 32 is convexly provided with a spherical protrusion 202, and the side wall of the support plate 21 away from the power shaft 32 is used to support the crystal. Alternatively, a spherical protrusion 202 is provided on the side of the support seat 23 facing away from the power shaft 32, and an assembly protrusion is provided on the side of the support plate 21 facing the power shaft 32, and the assembly protrusion is recessed with a rear spherical groove 201 along the thickness direction of the support plate 21 to meet the movable connection between the support plate 21 and the support seat 23.

[0049] Exemplarily, the spherical protrusion 202 is clamped in the spherical groove 201. At this time, the spherical protrusion 202 and the spherical groove 201 can be a whole sphere (referred to as a whole sphere), or can be between a whole sphere and a hemisphere.

[0050] Please continue reading Figures 3 to 6Alternatively, the support assembly 20 further includes an elastic connection structure 24, which passes through the support plate 21 and is connected to the support seat 23. That is to say, by using the setting of the elastic connection structure 24, the connection reliability of the support plate 21 relative to the support seat 23 can be further improved to prevent the support plate 21 from being separated; and, such a setting allows sufficient degrees of freedom between the support plate 21 and the support seat 23, which is more conducive to the relative movement of the support plate 21 to the support seat 23. In actual use, the spherical protrusion 202 and the spherical groove 201 can also be hemispherical, which is convenient for manufacturing while satisfying the degree of freedom; and, compared with a structure larger than a hemispherical shape, it can save materials.

[0051] See also Figure 3 and Figure 4 Optionally, the elastic connection structure 24 includes a connecting column 241, an elastic member 242 and a limit baffle 243. One end of the connecting column 241 along the first axial direction passes through the support plate 21 and is threadedly connected to the support seat 23, and the other end of the connecting column 241 is hinged to the limit baffle 243. The elastic member 242 is connected between the limit baffle 243 and the support plate 21, and is used to apply a restoring force to the support plate 21. The setting of the connecting column 241 mainly plays a role in fixing the support plate 21 and the support seat 23 to prevent the support plate 21 from being separated from the support seat 23. The setting of the elastic member 242 is used to ensure that the support plate 21 can return to its initial state after the activity. The elastic member 242 is sleeved on the connecting column 241. The elastic member 242 adopts a spring. The limit baffle 243 is clamped on the support plate 21 to cooperate with the connecting column 241 and the elastic member 242 to ensure that the elastic member 242 can act on the support plate 21.

[0052] When the spherical protrusion 202 is disposed on the support plate 21, the spherical protrusion 202 is configured with a through hole for the connection column 241 to pass through, and the aperture of the through hole is larger than the diameter of the connection column 241, so that the support plate 21 can move under the action of the adjustment structure 22. The inner diameter of the elastic member 242 is larger than the aperture of the through hole to ensure that there is a contact area between the elastic member 242 and the spherical protrusion 202, so as to apply a force to the support plate 21.

[0053] In actual use, a side of the support plate 21 away from the support seat 23 is concavely provided with a receiving groove 2101 along the first axial direction toward the side of the power shaft 32, and an end of the connecting column 241 away from the support seat 23 and the limiting baffle 243 are both accommodated in the receiving groove 2101. Since the side of the support plate 21 away from the support seat 23 is used to support the crystal, it is necessary to ensure the flatness of this side. Therefore, the connecting column 241 and the limiting baffle 243 need to be accommodated in the receiving groove 2101 to ensure that they will not protrude relative to the support plate 21, thereby reducing interference with the crystal. Among them, the connecting column 241 and the limiting baffle 243 are hinged, and the limiting baffle 243 is clamped at a position close to the notch of the receiving groove 2101.

[0054] See also Figure 5 and Figure 6 Alternatively, the limit baffle 243 is fixedly connected to the connecting column 241, or they can be integrally formed.

[0055] See also Figures 3 to 6 In some embodiments, the support assembly 20 further includes an assembly seat 25 having a receiving cavity 2501, and each adjustment structure 22 is received in the receiving cavity 2501. The assembly seat 25 is sleeved on the connecting shaft 33, and each adjustment structure 22 is connected to the assembly seat 25 and / or the connecting shaft 33.

[0056] In actual use, each adjustment structure 22 can be a cylinder, a hydraulic cylinder or an electric push rod. The structure of each adjustment structure 22 can be the same or different, as long as it can meet the linear drive to achieve the pitch angle adjustment of the support plate 21. In some specific embodiments, each adjustment structure 22 uses a hydraulic cylinder, including a second cylinder body and a second piston rod slidably connected to the second cylinder body, and each second piston rod serves as an actuating rod of the respective adjustment structure 22 to be connected to the support plate 21.

[0057] like Figure 1 As shown, illustratively, the clamping jaw assembly 10 also includes a clamping jaw seat 12, and the clamping jaw seat 12 is connected to the assembly shell 31. Each clamping arm 11 can be rotatably connected to the clamping jaw seat 12 to achieve clamping and loosening. The number of clamping arms 11 is two, and they are set at an interval of 180 degrees; it can also be three, and they are set at an interval of 120 degrees; it can even be 4, and they are set at an interval of 90 degrees. The number of clamping arms 11 should not be too many, which will not only waste resources and make assembly inconvenient, but also may cause crystal wear due to the larger clamping range with the crystal; it should not be too few, which will affect the clamping stability.

[0058] like Figure 1 , Figure 2 , Figure 3 and Figure 5In the optional embodiment shown, the grinding machine headstock also includes a turntable 60 having a second axis, and the integrated seat 50 is installed on the turntable 60, and the integrated seat 50 can rotate around the second axis under the action of the turntable 60. The clamping jaw assembly 10, the rotary drive assembly 30 and the linear drive assembly 40 are all installed on the integrated seat 50. Among them, the second axis is set at an angle with the first axis. The direction of the second axis is the Z axis direction. It can be understood that the angle adjustment of the clamping jaw assembly 10 and the support assembly 20 can be achieved by setting the turntable 60 to correspond to the structures corresponding to different operation procedures. For example, when end face grinding is required, the turntable 60 can be used to rotate the grinding machine headstock to the support plate 21 and the grinding wheel of the end face grinding; when rolling grinding (i.e., circumferential surface grinding) is required, the turntable 60 can be used to rotate the grinding machine headstock to the support plate 21 and the pressure head of the grinding machine tailstock; when orientation is required, it can be rotated to the station where the crystal orientation instrument is located. Such a setting can realize position switching between multiple workstations without the need to change different grinders multiple times, thereby improving grinding efficiency.

[0059] The turntable 60 includes a turntable and a rotating shaft rotatably connected to the turntable, and is driven by a motor. The integrated seat 50 is connected to the rotating shaft to realize the rotation drive of the integrated seat 50. Alternatively, a turntable is installed on the rotating shaft, the turntable is connected to the integrated seat 50, and the rotating shaft drives the integrated seat 50 to rotate around the second axis through the turntable. The integrated seat 50 is configured with a barrel cavity 501, and the rotation drive assembly 30 is installed in the barrel cavity 501, and partially extends out of the barrel cavity 501 to connect the support plate 21 and the clamping jaw assembly 10.

[0060] An embodiment of the present application provides a grinding machine, including a machine table and a grinding mechanism, a grinder headstock and a grinder tailstock arranged on the machine table. The grinder headstock and the grinder tailstock are arranged opposite to each other and spaced apart along a first axial direction, and the grinder tailstock has a pressure head, and the pressure head can move relative to a support plate of the grinder headstock along the first axial direction to get closer to or farther away from it. In actual use, the grinder headstock and the grinder tailstock cooperate to clamp the crystal in the thickness direction for grinding the circumferential surface of the crystal; and the grinder headstock itself can also fix the crystal for grinding the end face of the crystal. The support plate can also fix the crystal by adsorption for crystal orientation.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
