[0055] Furthermore, the first clamping assembly 3, the second clamping assembly 4, and the support frame 2 are all located inside the oil collection tank 1. The sliding drive mechanism 5 and the rotary drive mechanism 6 are located inside or outside the oil collection tank 1. The first clamping assembly 3, the second clamping assembly 4, and the support frame 2 are arranged in the same straight line direction. The first clamping seat 31 and the second clamping seat 41 can move towards or away from the support frame 2, so that the first clamping rod 32 and the second clamping rod 42 clamp the two ends of the workpiece placed on the support frame 2. The rotary drive mechanism 6 can drive the first clamping rod 32 or the second clamping rod 42 to rotate, and drive the workpiece to rotate, so that the residual oil attached to the workpiece can be thrown out, thereby cleaning the residual oil attached to the surface of the workpiece.

[0056] In addition, the oil collection tank 1 can limit the splashing of residual oil to the outside of the oil collection tank 1, and can collect the splashed residual oil inside the oil collection tank 1, so as to achieve the recycling of residual oil, reduce the processing cost of workpieces, and improve the on-site working environment.

When the oil throwing operation is performed, the switch door 12 can be closed, so that the inside of the oil collecting tank 1 is relatively sealed, and the splashing of the residual oil thrown out of the oil collecting tank 1 is avoided.

[0065] In some embodiments of the present application, as shown in Figure 3 The sliding drive mechanism 5 is a clamping cylinder 51, the rotating drive mechanism 6 is a pneumatic motor 61, and the switch door 12 and the inlet and outlet 11 are provided with a door locking cylinder 13 for locking the switch door 12;

[0066] Further, the control system 7 is provided, and the control system 7 comprises a gas source assembly 71, a main control valve 72, a sub-control valve 73 and a first reversing valve 74. The output end of the gas source assembly 71 is connected with the input end of the main control valve 72 and the input end of the first reversing valve 74 respectively. The output end of the main control valve 72 is connected with the input end of the sub-control valve 73, the clamping cylinder 51 and the reversing end of the first reversing valve 74 respectively.

An emergency stop switch is arranged between the air source assembly 71 and the main control valve 72, which is used to cut off the air path between the air source assembly 71 and the main control valve 72.

[0071] In the main control system, when the switch door 12 is opened, the first output end of the first switching valve 74 is opened, the second output end of the first switching valve 74 is closed, so that the air source assembly 71 can pass through the first output end of the first switching valve 74 to the first input port of the door locking cylinder 13 to drive the door locking cylinder 13 to remain unlocked. When the switch door 12 is closed, the switch door 12 triggers the main control valve 72 to open, and the air source assembly 71 passes through the main control valve 72 to the switching end of the first switching valve 74, so that the first switching valve 74 is switched, at this time the first output end of the first switching valve 74 is closed, the second output end of the first switching valve 74 is opened, and the air source assembly 71 passes through the second output end of the first switching valve 74 to the second input port of the door locking cylinder 13, so that the door locking cylinder 13 is locked, and the switch door 12 cannot remain closed and cannot be opened.

[0080] Further, the output end of the first delay valve 751 is connected with the reversing end of the second reversing valve 752, when the master valve 72 is opened, the air path between the air source assembly 71 and the pneumatic motor 61 is connected, at this time the pneumatic motor 61 is actuated, when the pneumatic motor 61 runs to the first preset time, the first delay valve 751 is opened, so that the air source assembly 71 can ventilate to the reversing end of the second reversing valve 752 through the first delay valve 751, at this time the second reversing valve 752 is reversed, so that the air path between the sub-control valve 73 and the pneumatic motor 61 is switched, and the pneumatic motor 61 can stop actuating. Wherein, by setting the first delay valve 751, the pneumatic motor 61 can stop actuating after the first preset time, without manually controlling the sub-control valve 73 to open or close, the work efficiency is improved.

At this time, the door locking cylinder 13 is unlocked, and the door 12 can be opened. Since the pneumatic motor 61 will continue to drive the workpiece to rotate under the action of inertia after stopping ventilation, in order to avoid the door 12 being opened artificially during the inertia stage, the second delay valve 761 is provided to make the pneumatic motor 61 stop ventilation after the first preset time, and to make the pneumatic motor 61 stop completely after the second preset time, so as to trigger the door locking cylinder 13 to unlock, thereby improving the safety of the operation.

[0087] Optionally, the input end of the second delay valve 761 is connected to the output end of the master valve 72, and the output end of the second delay valve 761 is connected to the reversing end of the third reversing valve 762. The second preset time is greater than the first preset time, so that the pneumatic motor 61 stops completely after the difference between the second preset time and the first preset time after the pneumatic motor 61 stops ventilation, and then triggers the door locking cylinder 13 to unlock.

[0088] In some embodiments of the present application, as shown in Figure 3 The control system 7 further includes a fourth reversing valve 77. The output end of the master valve 72 is connected to the input end of the fourth reversing valve 77. The first output end of the third reversing valve 762 is connected to the first reversing end of the fourth reversing valve 77, and the second output end of the third reversing valve 762 is connected to the second reversing end of the fourth reversing valve 77. The first output end of the fourth reversing valve 77 is connected to the first input port of the clamping cylinder 51, and the second output end of the fourth reversing valve 77 is connected to the second input port of the clamping cylinder 51.

[0089] When the second delay valve 761 is closed, the first output end of the fourth reversing valve 77 is opened, the second output end of the fourth reversing valve 77 is closed, the gas path between the input end of the fourth reversing valve 77, the first output end of the fourth reversing valve 77 and the first input port of the clamping cylinder 51 is communicated, and the clamping cylinder 51 keeps the clamping state;

[0090] When the second delay valve 761 is opened, the first output end of the fourth reversing valve 77 is closed, the second output end of the fourth reversing valve 77 is opened, the gas path between the input end of the fourth reversing valve 77, the second output end of the fourth reversing valve 77 and the second input port of the clamping cylinder 51 is communicated, and the clamping cylinder 51 keeps the loosening state.

[0091] Further, the clamping cylinder 51 is provided with two groups, and the two groups of clamping cylinders 51 are connected with the fourth reversing valve 77, so that the two groups of clamping cylinders 51 can act synchronously. When the first input port of the clamping cylinder 51 is ventilated, the clamping cylinder 51 keeps the clamping state, that is, the two groups of clamping cylinders 51 respectively drive the first clamping seat 31 and the second clamping seat 41 to move towards each other, so that the first clamping rod 32 and the second clamping rod 42 clamp the two ends of the workpiece. When the second input port of the clamping cylinder 51 is ventilated, the clamping cylinder 51 keeps the loosening state, that is, the two groups of clamping cylinders 51 respectively drive the first clamping seat 31 and the second clamping seat 41 to move away from each other, so that the first clamping rod 32 and the second clamping rod 42 are separated from the two ends of the workpiece. At this time, the workpiece can be taken out.

[0092] Further, the first output end of the third reversing valve 762 is connected with the first reversing end of the fourth reversing valve 77. Therefore, when the second delay valve 761 is closed, the first reversing end of the fourth reversing valve 77 is ventilated. At this time, the first output end of the fourth reversing valve 77 is opened, the second output end of the fourth reversing valve 77 is closed, so that the gas source assembly 71 can ventilate the first input port of the clamping cylinder 51 through the first output end of the fourth reversing valve 77, so that the clamping cylinder 51 keeps clamping. When the second delay valve 761 is opened, the reversing end of the third reversing valve 762 is ventilated, the first output end of the third reversing valve 762 is closed, and the second output end of the third reversing valve 762 is opened, so that the second reversing end of the fourth reversing valve 77 is ventilated, the fourth reversing valve 77 is reversed, the first output end of the fourth reversing valve 77 is closed, and the second output end of the fourth reversing valve 77 is opened, so that the gas source assembly 71 ventilates the second input port of the clamping cylinder 51 through the second output end of the fourth reversing valve 77, so that the clamping cylinder 51 keeps loosening.

[0093] Since the second delay valve 761 is provided, the clamping cylinder 51 can be loosened after the gas motor 61 completely stops, so that the workpiece is prevented from being separated from the support frame 2 due to the loosening of the clamping cylinder 51 under the action of inertia, and the operation safety is improved.

[0094] In some embodiments of the present application, as shown in Figure 2 The first clamping seat 31 is fixedly connected to the first sliding plate 15, the second clamping seat 41 is fixedly connected to the second sliding plate 16, the rotary driving mechanism 6 is fixed to the first sliding plate 15 and is in transmission with the first clamping rod 32, and the two sliding driving mechanisms 5 are respectively connected to the first sliding plate 15 and the second sliding plate 16.

[0095] In some embodiments of the present application, as shown in Figure 4 The bottom of the oil collecting tank 1 is provided with an oil discharging and recycling port 14.

[0096] The oil discharging and recycling port 14 can be connected to an external recycling mechanism to filter and treat the collected residual oil.

[0097] The above is only the principle and preferred embodiment of the present application. It should be noted that, for those skilled in the art, on the basis of the principle of the present application, several other variations can also be made, which should also be considered as the protection scope of the present application.
