It is understood that in other embodiments, the processing tool 100 may be used to process other workpieces, and is not limited thereto.
The machining apparatus 100 includes a main frame 20, a machining head 40, and a power unit 60. The processing head 40 and the power device 60 are both arranged on the main frame 20, the processing head 40 can be used for processing a milling cutter for the grooves of the aluminum template, the power device 60 is in transmission connection with the processing head 40, and the power device 60 is used for driving the processing head 40 to reciprocate in a first direction, so that the groove milling operation of the aluminum template is completed. Wherein the first direction is the direction of gravity. It will be appreciated that the processing apparatus 100 may also include other means to drive the processing head 40 in a horizontal or other direction.
With reference to fig. 1 and fig. 2, the power device 60 includes a power unit 61, a first control unit, a speed regulation unit 63, a second control unit, and a connection assembly 65. The power unit 61 drives the speed regulating unit 63 to synchronously operate under the control of the first control unit so as to drive the machining head 40 to reciprocate in the first direction, and the second control unit is used for accurately controlling the operation state of the speed regulating unit 63, so that the stable operation of the power unit 61 is realized. In this way, the power unit 61 and the speed regulating unit 63 work in cooperation to drive the machining head 40 to ascend and descend smoothly and accurately in the first direction.
The power unit 61 includes a first cylinder 612 and a first piston assembly 614. A first cylinder 612 is mounted to the main frame 20, the first cylinder 612 having a power chamber extending in a first direction. First piston assembly 614 includes first piston rod and locates the first piston of first piston rod one end, and the external diameter of first piston matches with the internal diameter of power chamber. The end, provided with the first piston, of the first piston assembly 614 is inserted into the power cavity, the first piston divides the power cavity into a first sub power cavity 6121 and a second sub power cavity 6123, the first sub power cavity 6121 is located below the second sub power cavity 6123, and the end, far away from the first piston, of the first piston assembly 614 extends out of the power cavity to be connected with the connecting assembly 65.
The first control unit is connected to the first cylinder 612 for delivering compressed gas to the power chamber to drive the first piston assembly 614 to reciprocally extend and retract in a first direction. Specifically, the first control unit includes an air source structure (not shown), a first air pipeline 621 and a second air pipeline 623, and a first connection hole communicating with the first sub-power chamber 6121 and a second connection hole communicating with the second sub-power chamber 6123 are respectively formed at two ends of the first cylinder 612 in the first direction. One end of the first gas transmission pipeline 621 is inserted into the gas source structure, the other end of the first gas transmission pipeline 621 is inserted into the first connection hole to communicate with the first sub-power cavity 6121, one end of the second gas transmission pipeline 623 is inserted into the gas source structure, and the other end of the second gas transmission pipeline 623 is inserted into the second connection hole to communicate with the second sub-power cavity 6123.
Thus, two ends of the first gas transmission pipeline 621 are respectively connected to the gas source structure and the first sub-power cavity 6121, and two ends of the second gas transmission pipeline 623 are respectively connected to the gas source structure and the second sub-power cavity 6123. When the air supply structure inputs compressed air into the first sub-power chamber 6121 through the first air delivery pipe 621, the first piston assembly 614 moves upward under the push of the compressed air, and the air in the second sub-power chamber 6123 flows out through the second air delivery pipe 621. When the gas source structure inputs compressed gas into the second sub-power chamber 6123 through the second gas transmission pipeline 623, the first piston assembly 614 moves downward under the pushing of the compressed gas, and the gas in the first sub-power chamber 6121 flows out through the first gas transmission pipeline 621.
Since the expansion and contraction speed of the first piston assembly 614 is difficult to be stabilized due to the compressibility of the gas, the power device 60 further includes a governor unit 63, and the governor unit 63 is used for stabilizing the expansion and contraction speed of the first piston assembly 614.
Specifically, the governor unit 63 includes a second cylinder 632 and a second piston assembly 634. The second cylinder 632 is mounted to the main frame 20 on one side of the first cylinder 612 in the horizontal direction, and the second cylinder 632 has a speed adjusting chamber extending in the first direction. The second piston assembly 634 includes a second piston rod and a second piston disposed at one end of the second piston rod, and the outer diameter of the second piston is matched with the inner diameter of the speed regulation cavity. The end of the second piston assembly 634 provided with the second piston is inserted into the speed regulation cavity, the second piston divides the speed regulation cavity into a first sub speed regulation cavity 6321 and a second sub speed regulation cavity 6323, the first sub speed regulation cavity 6321 is located below the second sub speed regulation cavity 6323, and the end of the second piston assembly 634 far away from the second piston extends out of the speed regulation cavity to be connected with the connection assembly 65.
The second control unit is connected to the second cylinder 632 for supplying hydraulic oil to the speed regulation chamber to control the moving speed of the second piston assembly 634 in the second direction. Specifically, the second control unit includes an oil storage container 641, a first oil pipeline 643 and a second oil pipeline 645, and two ends of the second cylinder 632 in the first direction are respectively provided with a third connection hole communicating with the first sub speed regulation cavity 6321 and a fourth connection hole communicating with the second sub speed regulation cavity 6323. One end of the first oil pipeline 643 is inserted into the oil storage container 641, the other end of the first oil pipeline 643 is inserted into the third connecting hole to communicate with the first sub speed regulation cavity 6321, one end of the second oil pipeline 645 is inserted into the oil storage container 641, and the other end of the second oil pipeline 645 is inserted into the fourth connecting hole to communicate with the second sub speed regulation cavity 6323.
Thus, the oil reservoir 641 and the first sub speed control chamber 6321 are connected to both ends of the first oil passage 643, and the oil reservoir 641 and the second sub speed control chamber 6323 are connected to both ends of the second oil passage 645. When the hydraulic oil in the oil reservoir 641 flows into the first sub speed regulation chamber 6321 through the first oil passage 643, the second piston assembly 634 moves upward by the urging of the hydraulic oil, and the hydraulic oil in the second sub speed regulation chamber 6323 flows into the oil reservoir 641 through the second oil passage 645. When the hydraulic oil in the oil reservoir 641 flows into the second sub speed regulation chamber 6323 through the second oil delivery pipe 645, the second piston assembly 634 moves downward by the urging of the hydraulic oil, and the hydraulic oil in the first sub speed regulation chamber 6321 flows into the oil reservoir 641 through the first oil delivery pipe 643.
In addition, since the total volume of the governor cavity varies with the extension and contraction of the second piston assembly 634, when the governor cavity is filled with hydraulic oil, the volume of the hydraulic oil in the oil reservoir 641 is one third of the total volume of the oil reservoir 641, so as to accommodate the difference between the volumes of the first governor cavity 6321 and the second governor cavity 6323, and support the stable operation of the power device 60.
Further, the second control unit further includes a speed regulating assembly 647, the speed regulating assembly 647 is installed on the first oil pipeline 643 and/or the second oil pipeline 645, and the speed regulating assembly 647 is used for controlling the flow rate of the hydraulic oil input into and/or output from the speed regulating cavity. Specifically, in some embodiments, the speed adjustment assembly 647 includes a speed adjustment valve 6472 and a one-way valve 6474 connected in parallel with the speed adjustment valve 6472, the speed adjustment valve 6472 is used to adjust the flow rate of the hydraulic oil flowing therethrough, and the one-way valve 6474 allows the hydraulic oil in the oil reservoir 641 to flow into the second cylinder 632 in one direction. Thus, the governor valve 6472 works in conjunction with the check valve 6474 to regulate the rate at which hydraulic oil flows into and/or out of the governor cavity.
Thus, by utilizing the incompressibility of the fluid, the second control unit controls the flow rate of the hydraulic oil flowing into and out of the speed regulation chamber, so that the second piston assembly 634 is stably extended and contracted, and the whole power device 60 is stably operated.
As shown in fig. 1, the connecting assembly 65 includes a first connecting portion 652 and a second connecting portion 654 connected to each other, the first connecting portion 652 connecting an end of the first piston assembly 614 extending out of the power chamber with an end of the second piston assembly 634 extending out of the speed chamber, and the second connecting portion 654 being connected to the processing head 40.
Thus, the first piston assembly 614 drives the second piston assembly 634 to synchronously extend and retract in the first direction through the connecting assembly 65, and the first piston assembly 614 and the second piston assembly 634 are connected with the processing head through the connecting assembly 65, so as to drive the processing head to lift in the first direction together. It will be appreciated that the specific configuration of the linkage assembly 65 is not limited and may be provided in different shapes as desired.
In the power device 60, the first control unit controls the first piston assembly 614 of the power unit 61 to extend and contract in the first direction, so as to drive the second piston assembly 634 to extend and contract in the first direction. And the second control unit may control the extension and contraction speed of the second piston assembly 634 in the first direction by controlling the flow rate of the hydraulic oil, and in turn, the extension and contraction speed of the first piston assembly 614 in the first direction. The first piston assembly 614 and the second piston assembly 634 move synchronously in the first direction, thereby driving the machining head 40 to operate stably.
The power device 60 and the processing equipment 100 combine the characteristics of simple operation and convenient maintenance of the power unit 61 driven by compressed air and the characteristics of good operation stability of the speed regulating unit 63 driven by hydraulic oil, meet the requirements of the processing equipment 100, improve the processing precision of the aluminum template, simplify the structure of the power device 60 and reduce the manufacturing cost of the aluminum template.
Fig. 3 shows a flowchart of a control method of the power plant of an embodiment of the invention. As shown in fig. 3, the control method of the power plant 60 includes the following steps:
s110: the first piston assembly 614 is controlled to extend and retract in a first direction relative to the first cylinder 612, and the first piston assembly 614 passes through the connecting assembly 65 and drives the second piston assembly 634 to extend and retract in the first direction relative to the second cylinder 632.
Specifically, first, the governor cylinder is filled with hydraulic oil, and the volume of hydraulic oil in the oil reservoir 641 is secured to be one third of the total volume of the oil reservoir 641.
Then, the first control unit inputs compressed gas into the first cylinder 612 to control the first piston assembly 614 to extend and contract along the first direction relative to the first cylinder 612, and the first piston assembly 614 drives the second piston assembly 634 to extend and contract along the first direction relative to the second cylinder 632 through the connecting assembly 65.

S120: hydraulic oil is delivered to the second cylinder 632 to control the extension and contraction speed of the second piston assembly 634 in the first direction.
Specifically, the second control unit delivers hydraulic oil to the speed regulation chamber of the second cylinder block 632 and controls the flow rate of hydraulic oil flowing into and out of the speed regulation chamber, thereby precisely controlling the extension and contraction speed of the second piston assembly 634 in the first direction, and the second piston assembly 634 in turn controls the extension and contraction speed of the first piston assembly 614 in the first direction. The first piston assembly 614 and the second piston assembly 634 move synchronously in the first direction, thereby driving the machining head 40 to operate stably. s
In the control method of the power device 60, the first control unit and the second control unit work cooperatively, and the power unit 61 and the speed regulating unit 64 are controlled to work cooperatively, so that the machining head 40 is accurately and stably driven to reciprocate.
