For example, in one embodiment, as shown in fig. 4, two pressing pads, i.e., an upper pressing pad 216 and a lower pressing pad 217, are respectively disposed on the upper and lower bottom surfaces of the micro-removal action body 212, the micro-removal action base 213 simultaneously passes through central through holes of the micro-removal action body 212 and the two pressing pads, the upper pressing pad 216 is axially limited by a shoulder of the micro-removal action base 213 and cannot move upward, and the two pressing pads are screwed and pressed by the pressing nut 218 on the lower portion to fixedly connect the micro-removal action base 213 and the micro-removal action body 212.

In one embodiment, the spindle module 210 may also directly adopt the corresponding components and parts described in the conventional micro-removing device in the prior art, such as CN201620171998.6, CN201720277716.5, CN201621137181.3, etc., to form the corresponding spindle module 210.

In another embodiment, the spindle module 210 uses the corresponding components of the micro-removing devices such as CN201810703729.3, CN201810704421.0, and CN201810704422.5 to form the corresponding spindle module 210. At this time, it is preferable that the micro removing device is further provided with a corresponding water supply system, hereinafter, a water supply unit 810.

In one embodiment, the spindle unit 200 includes only one spindle module 210.

In another embodiment, the spindle unit 200 includes two or more spindle modules 210, such as two, three, four, five, six, seven, eight, nine, or even ten, twelve, etc. In combination with practical application requirements and cost requirements, the spindle unit 200 comprises four, five, six, eight, ten or twelve spindle modules 210.

The workpiece clamping unit 600 is mainly used for clamping and fixing a slightly removed workpiece. In practice, the fitting clamp 121 described in CN2013101125349 and the clamp system described in CN201710898080 can be referred to a plurality of prior arts.

For a rotary cylindrical or conical workpiece, as shown in fig. 5, if the wall thickness is thin, the workpiece clamping unit 600 in the prior art often causes deformation of the workpiece when clamping the workpiece, or the workpiece is not firmly clamped and is easily loosened, so that the micro-removal effect is greatly affected. For effectively solving the problem, the utility model adopts a novel copying clamping technology.

In one embodiment, as shown in fig. 6, the workpiece clamping unit 600 includes a workpiece clamping module 610. The workpiece clamping module 610 mainly includes a clamping main member 611, a clamping sub-member 612, and a clamping power unit 613.

The clamping main member 611 can be sleeved in the workpiece cavity shown in fig. 5, and the shape of the clamping main member 611 is the same as or similar to the workpiece cavity, but the size of the clamping main member 611 is slightly smaller than the workpiece cavity so as to be convenient for taking out while fitting the workpiece cavity to the maximum extent, or the fitting area of the outer surface of the clamping main member 611 and the workpiece cavity exceeds more than 10% of the area of the workpiece cavity, and can also exceed 20%, 30%, 50%, 80% or even more than 90%. Preferably, the external dimension of the clamping main member 611 is 60% to 99.999% of the corresponding dimension of the workpiece inner cavity, more preferably 90% to 99.999% of the corresponding dimension of the workpiece inner cavity, more preferably 95% to 99.999% of the corresponding dimension of the workpiece inner cavity, and even more preferably 98% to 99.9% of the corresponding dimension of the workpiece inner cavity, so as to maximize the attaching effect and facilitate the taking out.

In one embodiment, as shown in fig. 7, the clamping main member 611 is provided with a plurality of open grooves 611-1, and the open grooves 611-1 are recessed downward from the upper bottom surface 611-2 of the main member in the radial direction of the clamping main member 611, but are not recessed to the lower bottom surface 611-3 of the main member, but are spaced from the lower bottom surface 611-3 of the main member by a certain distance M.

The clamping main member 611 is provided with at least two open grooves 611-1.

When the clamping main member 611 is provided with N open grooves 611-1, the N open grooves 611-1 divide the clamping main member 611 into N elastic blocks 611-4. When the clamping main member 611 is sleeved in the inner cavity of the workpiece, each elastic block 611-4 can be pushed outwards by the clamping auxiliary member 612 to press the workpiece, and when the pushing outwards action of the clamping auxiliary member 612 is removed, each elastic block 611-4 can automatically rebound to the normal shape by means of the elastic force of the elastic block 611-4 to be separated from the workpiece. The automatic rebounding mechanism is simple and reliable in structure, and the cost and the space of the rebounding mechanism can be saved.

In another embodiment, the resilient block 611-4 may be returned to the normal configuration by pulling inward on the clamping sub-assembly 612.

In one embodiment of the automatic compensation function, when the contact force between the workpiece and the micro-removal effector 212 is too large or too small, the small Y-axis module 410 maintains the contact force between the workpiece and the micro-removal effector 212 at the contact force required for the optimal micro-removal through the automatic compensation function of the electronic control unit 700, which can be specifically implemented with reference to the prior art such as CN201711159979.7, or can also adopt a new contact force automatic compensation technology. In the contact force automatic compensation technique, each driving motor 211 of each spindle module 210 uses a torque motor, so that when the contact force is different, the current value output by each torque motor driver can be directly used to represent the contact force, and the current value and the contact force are close to a linear relationship and can be processed according to the linear relationship. In one embodiment, the small Y-axis module 410 drives the workpiece away from the micro-removal effector 212 a distance D when the actual contact force generated by the small Y-axis module 410 driving the workpiece closer to the micro-removal effector 212 exceeds the contact force required for optimal micro-removal, and the small Y-axis module 410 drives the workpiece closer to the micro-removal effector 212 a distance D when the actual contact force is less than the contact force required for optimal micro-removal. The contact force required by the optimal micro-removal and a certain distance D far away from or close to the optimal micro-removal are determined according to a test or trial processing mode to form a data table. In this data table, it is not specified that the distance D at the time of the distance is negative and the distance D at the time of the approach is positive. When the actual contact force (or the current value output by each torque motor driver) falls within the range interval corresponding to one contact force (or current value) in the data table, the electronic control unit 700 controls the small Y-axis module 410 to drive the workpiece to move away from or close to the micro-removal effector 212 by a corresponding distance according to the distance D in the data table. To reduce the number of tests required for the data sheet, in one embodiment, the contact force (or current value) is processed in a linear relationship to the distance D, i.e., the actual contact force F0 is recorded at the time of optimal micro-ablation, and then the actual contact force F1 is measured near the distance D1 (when D1 is positive), and the distance DX for the different contact forces FX is equal to ((FX-F0) × D1/(F1-F0)). If the actual contact force F1 is measured away from distance D1 (in this case D1 is negative), the distance DX for the different contact forces FX is equal to ((FX-F0) × D1/(F1-F0)).

In one embodiment, the ecu 700 records, stores and recalls data tables required for implementing the compensation function, or stores, calculates and recalls data and corresponding calculation formulas of the actual contact force F0, the distance D1, the actual contact force F1 and the like required for implementing the compensation function through the numerical control system 710. The numerical control system 710 is a CNC multi-axis linkage numerical control system, and controls the small Y-axis module 410 to drive the workpiece to move away from or approach the micro-removal effector 212 by a corresponding distance according to a numerical interpolation principle. In the specific implementation, the product specification of the existing numerical control system 710 may be referred to and directly implemented by combining with the actual numerical control system 710 product, or may be implemented by combining with a CNC numerical control machining center or a numerical control milling machine with a similar compensation function in the prior art (only relevant calculation formulas and corresponding numerical parameters are adjusted), and corresponding codes or program segments are added and called or executed according to the operation specification of the numerical control system 710.

In another embodiment of the automatic compensation function, when the distance between the workpiece and the micro-removing effector 212 is too large or too small, the small Y-axis module 410 maintains the distance between the workpiece and the micro-removing effector 212 at the distance required for the optimal micro-removal through the automatic compensation function of the electronic control unit 700, and the specific embodiment may refer to a plurality of existing products or existing technologies such as a numerically controlled milling machine or a numerically controlled machining center with the automatic compensation function, wherein when measuring the distance between the workpiece and the micro-removing effector 212, the distance may be directly measured by using various laser displacement sensors, or may indirectly measure the distance between a characteristic position of the workpiece and the rotating shaft of the micro-removing effector 212.

In one embodiment, as shown in fig. 12, in order to improve the working efficiency and achieve precise and high-quality micro-removal of two or more workpieces by one micro-removal device, two or more small Y-axis modules 410 are fixedly connected to the X-axis table 123 (in this case, the X-axis unit 120 is fixed to the Y-axis table 133), each C-axis module 510 and the workpiece holding module 610 are fixedly connected to form one C-axis workpiece holding module as shown in fig. 9, and one C-axis workpiece holding module is fixedly connected to the small Y-axis table 413 of each small Y-axis module 410. Preferably, the number of small Y-axis modules 410 is three, four, five, six, seven, eight, nine, ten, twelve, twenty. Preferably, the number of small Y-axis modules 410 is four, five, six, eight, or ten, with a better balance of efficiency, cost, and user purchase.

In another embodiment, two or more small Y-axis modules 410 are fixedly attached directly to the Y-axis table 133.

In one embodiment, the number of spindle modules 210 is less than the number of small Y-axis modules 410, and when the workpiece position is adjusted by fine position control of the X-axis unit 120, the X-axis stage 123 of the X-axis unit 120 is moved after a batch of workpieces has been micro-removed to bring the non-micro-removed workpieces closer to the nearest spindle module 210 to complete micro-removal.

In one embodiment, the number of spindle modules 210 is greater than the number of small Y-axis modules 410, and the workpiece positions are adjusted by fine position control of the X-axis unit 120 such that all the workpieces that are not micro-machined are aligned and close to their nearest spindle modules 210 while micro-machining is performed at once, even though the spindle modules 210 are not involved in micro-machining.

In one embodiment, each small Y-axis module 410 corresponds to a spindle module 210, the number of the spindle modules 210 is the same as that of the small Y-axis modules 410, and each spindle module 210 is aligned with each corresponding small Y-axis module 410, so that each workpiece can be precisely aligned with the micro-removal effector 212 on the corresponding spindle module 210 without moving the X-axis table 123, and micro-removal of each workpiece can be completed at one time. At this time, if the automatic compensation function is adopted, the automatic compensation function is directed to the workpiece in which the absolute value of the difference of the actual contact force with respect to the optimal micro-removal time is the largest, or the workpiece in which the absolute value of the difference of the actual pitch with respect to the optimal micro-removal time is the largest.

In one embodiment, the same driving motor is used by each spindle module 210 of the spindle unit 200 to provide rotational power for the rotation of the micro removing element 212, and reference may be made to CN201620168396.5 and other prior arts.

In one embodiment, as shown in fig. 3, 4 and 13(c), each spindle module 210 of the spindle unit 200 is independently driven by a respective driving motor 211, that is, the number of driving motors 211 is the same as that of the spindle modules 210, and the driving motor 211 of each spindle module 210 is independent from the driving motors 211 of the other spindle modules 210. At this time, if the automatic compensation function is adopted, the driving motor 211 of each spindle module 210 is respectively matched with the corresponding small Y-axis module 410 to form local independent automatic compensation, so that the automatic compensation is individually performed for each workpiece according to the specific situation of each workpiece, each workpiece obtains the best micro-removal and the corresponding micro-removal quality, the qualification rate and the qualification rate of the micro-removal of the workpiece are greatly improved, moreover, when one small Y-axis module 410 or one spindle module 210 fails, other workpieces are not affected, the reliability of the simultaneous micro-removal of multiple workpieces is maximized, the rotation speed fluctuation of each independent spindle module 210 in the simultaneous compensation process of multiple workpieces does not affect the micro-removal of other spindle modules 210 and workpieces, the failure or the speed fluctuation of each independent small Y-axis module 410 in the simultaneous compensation process of multiple workpieces does not affect the micro-removal of other small Y-axis modules 410 and workpieces, in particular, when the number of workpieces is reduced, the spindle module 210 and the small Y-axis module 410 can be shut down or stopped without the workpieces, and the system power consumption and load can be flexibly reduced. Although the cost of the entire micro removing device is increased due to the cost increase of the driving motor 211 of the main shaft module 210 and the small Y-axis module 410, the cost of purchasing these parts in batches is reduced, and the multiple parts are simultaneously micro-removed and are respectively independently compensated automatically, so that the micro-removing efficiency, quality, flexibility, reliability and the like are greatly improved.

Meanwhile, in the micro-removing process, the numerical control system 710 controls the corresponding liquid supply PLC program to continuously supply liquid so that the spraying device 814 sprays liquid to the micro-removed part of the workpiece, thereby improving the micro-removing efficiency and quality and reducing the scattering of micro-debris. In order to prevent the liquid mixed with the micro-debris from flowing randomly and collect and treat the generated waste water and waste liquid, the bed body 110 is provided with a corresponding water tank according to a liquid flowing path or an expected path, so that the waste liquid is convenient to collect, recycle and even reuse, and the waste liquid is prevented from being discharged randomly.
