[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1 , Figure 2 As shown, a flip positioning clamping structure of a horizontal five-axis flip plate machining center includes: a base 1, a base plate 2 and a workbench 3; the base plate 2 is hinged on the base 1, and a flip device 4 is provided between the base plate 2 and the base 1, and a workbench positioning device 6 and a workbench clamping device 7 are provided on the base plate 2; columns 5 are provided on both sides of the base 1, and a base plate clamping device 8 is provided on the columns 5;

When the flipping device 4 drives the substrate 2 to flip from a horizontal position to a vertical position, the substrate clamping device 8 clamps the substrate 2 on the column 5.

[0041] The invention discloses a flip positioning clamping structure and method for a horizontal five-axis flip plate machining center. The accuracy of the workbench positioning is ensured by a workbench positioning device. During the clamping and flipping process, the workbench flipping and the fixation of the machining position are achieved by flipping the substrate and clamping the substrate. In the positioning, clamping and flipping process, the error is eliminated by the detection device to avoid the accumulation of errors and improve the machining accuracy. In addition, the exchange mode of a machining center for multiple workbenches is realized, which improves the overall production efficiency.

[0042] like Figure 3 , Figure 4 As shown, the workbench positioning device 6 includes a positioning cylinder 61 and a positioning piston rod 62 . The positioning cylinder 61 is arranged in the base plate 2 . A positioning hole 63 is arranged on the lower surface of the workbench 3 . The positioning piston rod 62 can extend into the positioning hole 63 .

[0043] like Figure 7 As shown, in this embodiment, two workbench positioning devices 6 are provided to ensure accurate positioning of the workbench.

[0044] In this embodiment, there are two workbench clamping devices 7, and the workbench clamping devices 7 include a clamping plate 71, a driving cylinder 72 and a first pad 73. The piston end of the driving cylinder 72 is fixedly connected to the clamping plate 71. The lower surface of the workbench 3 is provided with a mounting groove 74, and the clamping plate 71 is arranged in the mounting groove 74. Mounting plates 75 are provided on both sides of the mounting groove 74, and the mounting plates 75 are arranged between the clamping plate 71 and the first pad 73.

[0045] like Figure 3 The workbench 3 is shown in the non-clamped state, the mounting plate 75 and the first pad 73 are in a non-fitted state, the first driving rod 72 is started, the clamping plate 71 is pulled downward, the clamping plate 71 moves downward, the mounting plate 75 is pressed on the first pad 73, and the workbench 3 is clamped. Figure 4 shown.

[0046] like Figure 5 , Figure 6 As shown, the column 5 includes a first column 51 and a second column 52, and a hollow portion 53 is provided between the first column 51 and the second column 52. The substrate clamping device 8 is arranged in the hollow portion 53 and fixed to the first column 51. The substrate clamping device 8 includes a cylinder body 81, a piston rod 82 and a clamping arm 83. When the substrate 2 is in a vertical state, the piston rod 82 is perpendicular to the substrate 2. The first column 51 is provided with a second pad 84, and the second pad 84 is provided on one side of the cylinder body 81. The substrate 2 can be clamped between the second pad 84 and the clamping arm 83.

[0047] One side of the base plate 2 is hinged to the base 1, and the other side is equipped with a flip device 4. In this embodiment, the flip device 4 uses two hydraulic cylinders, and one end of the hydraulic cylinder body close to the piston rod outlet is hinged to the base 1, and the end of the piston rod is hinged to the other side of the base plate 2. The first column 51 is arranged on one side of the base 1 where the base plate 2 is hinged, and the second column 52 is arranged on both sides of the base 1. The first column 51 is a columnar structure, and the second column 52 is a plate-like structure. A crossbeam is arranged on the top of the two columns 5. The base 1, the columns 5 and the crossbeam cooperate to make the overall structure more stable, which is conducive to high-precision processing.

[0048] The substrate clamping device 8 is arranged in the hollow part 53 to avoid motion interference with the workbench 3 and the substrate 2. The substrate clamping device 8 controls the extension and retraction of the piston rod 82 through hydraulic oil, and rotates 90° during the extension and retraction process, that is, when the clamping arm 83 moves toward the cylinder body 81, it rotates 90° from the vertical direction to the horizontal position, so that the end of the clamping arm 83 can clamp the flipped substrate. The first column 51 is provided with a second pad 84. After the substrate 2 is flipped up, it is clamped between the clamping arm 83 and the second pad 84. The substrate airtightness detection port 115 is provided at the position corresponding to the substrate 2 and the second pad 84, which is used to detect whether the substrate is clamped on the column.

[0049] like Figure 3 , Figure 4 As shown, this embodiment also includes a positioning detection device 9;

[0050] The positioning detection device 9 includes a positioning seat 91 installed on the substrate 2, a first detection switch 92 and a second detection switch 93 installed on the positioning seat 91, and the workbench positioning device 6 includes a positioning piston rod 62, the upper end of the positioning piston rod 62 can be extended into the workbench 3, and the lower end of the positioning piston rod 62 can be extended from the lower surface of the substrate 2, and the lower end of the positioning piston rod 62 is provided with a positioning detection block 64. When the upper end of the positioning piston rod 62 extends into the workbench 3, the positioning detection block 64 corresponds to the first detection switch 92, and when the lower end of the positioning piston rod 62 retracts into the substrate 2, the positioning detection block 64 corresponds to the second detection switch 93.

[0051] like Figure 3 As shown, the workbench 3 is on the substrate 2, the positioning piston rod 62 moves upward, the upper end of the positioning piston rod 62 enters the positioning hole 63, and at the same time, the lower end of the positioning piston rod 62 moves upward, so that the positioning detection block 64 moves from the position of the second detection switch 93 to the position of the first detection switch 92. When the second detection switch 93 detects the positioning detection block 64, the workbench 3 is in a non-positioning state, and when the first detection switch 92 detects the positioning detection block 64, the workbench 3 is in a positioned state.

[0052] The present embodiment also includes a workbench clamping detection device 10, which includes a third detection switch 101 arranged on the upper surface of the substrate 2, and a detection surface 102 is arranged on the lower surface of the workbench 3. The distance between the detection surface 102 and the third detection switch 101 in the horizontal direction is smaller than the distance between the mounting plate 75 and the third detection switch 101 in the horizontal direction. When the mounting plate 75 is pressed against the first pad 73, the detection surface 102 corresponds to the position of the third detection switch 101.

[0053] The third detection switch 101 is installed on the substrate 2 through the switch mounting seat. When the workbench 3 is in a non-clamped state, the third detection switch 101 cannot detect the detection surface 102. Under the action of the clamping plate 71, the workbench 3 moves downward and is clamped on the substrate 2. The detection surface 102 moves with the workbench to the corresponding position of the third detection switch 101, and the third detection switch 101 detects that the workbench 3 is clamped. Fig. 9 As shown, the workbench clamping detection device 10 also includes a workbench air tightness detection device, which includes a workbench air tightness detection port 103 provided on the substrate 2 for detecting the clamping state of the workbench 3. The flipping action can be performed only when the third detection switch 101 and the workbench air tightness detection device both feed back clamping signals.

[0054] This embodiment also includes a substrate clamping detection device 11; the substrate clamping detection device 11 includes a mounting frame 111, a fourth detection switch 112 and a fifth detection switch 113, and a clamping detection block 114 is provided on the side of the clamping arm 83 away from the piston rod 82. When the piston rod 82 retracts and drives the clamping arm 83 to clamp the substrate 2, the position of the clamping detection block 114 corresponds to the fourth detection switch 112; when the piston rod 82 extends and drives the clamping arm 83 to release the substrate 2, the position of the clamping detection block 114 corresponds to the fifth detection switch 113.

[0055] The clamping arm 83 moves axially along the piston rod 82, driving the disc-shaped clamping detection block 114 to move simultaneously. When the clamping arm 83 clamps the substrate 2, the clamping detection block 114 moves to the fourth detection switch 112. When the clamping arm 83 releases the substrate 2, the clamping detection block 114 moves to the fifth detection switch 113. Figure 8 As shown, in order to further ensure the reliability of substrate clamping, the substrate clamping detection device 11 also includes a substrate air-tightness detection device, and the substrate air-tightness detection device includes a substrate air-tightness detection port 115 arranged on the upper surface of the substrate 2, and the substrate air-tightness detection port 115 corresponds to the position of the second pad 84. When the sixth detection switch 121 and the substrate air-tightness detection simultaneously feedback the clamping state, the workpiece on the workbench is in a state to be processed.

[0056] like Figure 7 , Figure 8 As shown, this embodiment further includes a flip-up detection device 12 and a fall-back detection device 13;

[0057] The flip-up detection device 12 comprises a sixth detection switch 121. When the substrate 2 is flipped up to a vertical position, the sixth detection switch 121 corresponds to the side surface of the substrate 2.

[0058] In this embodiment, the sixth detection switch 121 is disposed on the cylinder body 81. After the substrate 2 is flipped to a vertical state, the side of the substrate 2 moves to a position detectable by the sixth detection switch 121. After the sixth detection switch 121 detects the substrate 2, it is determined that the substrate has been flipped into place, and a signal is sent to perform a substrate clamping action.

[0059] The falling-back-to-position detection device 13 comprises a seventh detection switch 131, which is arranged on the column 5. When the substrate 2 falls back to the horizontal position, the seventh detection switch 131 corresponds to the side surface of the substrate 2;

[0060] After the seventh detection switch 131 detects the substrate 2, it determines that the substrate has fallen back into place, and sends a signal to release the workbench.

[0061] This embodiment also discloses a flipping, positioning and clamping method for a horizontal five-axis flap machining center, comprising the following steps:

[0062] S1, adjusting the position of the workbench on the substrate, and the workbench positioning device positions the workbench; after the workbench positioning device completes the positioning, the positioning detection device detects that the positioning is completed;

[0063] S2, the workbench clamping device clamps the workbench onto the substrate, and the workbench clamping detection device detects that the clamping is completed;

[0064] S3, the flipping device drives the substrate to flip from the horizontal position to the vertical position; the flipping detection device detects that the substrate is flipped to the set position;

[0065] S4, the substrate clamping device clamps the substrate on the column, and the substrate clamping detection device detects that the clamping is completed;

[0066] S5, enter the processing state;

[0067] S6. After the processing is completed, the substrate clamping device releases the substrate, the flipping device drives the substrate to flip from the vertical position to the horizontal position, and the falling-back detection device detects that the substrate has fallen back to the set position.

[0068] Specifically, the workpiece to be processed is fixed on the workbench. After the workbench moves to the specified position on the base plate, the positioning cylinder drives the positioning piston rod to extend toward the workbench, and the upper end of the positioning piston rod moves into the positioning hole to complete the positioning of the workbench.

[0069] The positioning detection block moves upward along with the positioning piston rod, the first detection switch detects the positioning detection block, the positioning is completed, and a positioning completion signal is issued;

[0070] The first driving oil cylinder drives the clamping plate to move downward, and the clamping plate presses the mounting plate onto the first pad. The third detection switch detects the detection surface and sends a signal. The air tightness between the mounting plate and the base plate is detected through the air tightness detection port of the workbench. Through the air tightness detection, the clamping state of the workbench is further determined.

[0071] The third detection switch and the workbench air tightness detection device both send signals to confirm that the workbench is clamped on the substrate, and then the flipping device drives the substrate to flip to a vertical position;

[0072] The sixth detection switch detects that the flap has been flipped to the set vertical position and sends a flip-in-place signal;

[0073] The cylinder of the substrate clamping device drives the piston rod to rotate and retract, and the piston rod drives the clamping arm to turn toward the substrate and press the substrate onto the second pad of the first column;

[0074] The fourth detection switch detects the clamping detection block, sends a signal, detects the air tightness between the substrate and the column through the substrate air tightness detection port, and further determines the clamping state of the substrate through the air tightness detection;

[0075] The fourth detection switch and the substrate air tightness detection device both send signals to confirm that the substrate is clamped, and the workpiece on the workbench enters the state of waiting for processing. Fig.10 As shown, the substrate is flipped up and clamped.

[0076] After the workpiece is processed, the substrate clamping device releases the substrate, and the fifth detection switch detects the clamping detection block, determines that the substrate is in a non-clamping state, and sends a signal;

[0077] The flipping device is activated to flip the substrate from a vertical state to a horizontal state;

[0078] After the seventh detection switch of the return-to-position detection device detects the substrate, it is determined that the substrate has returned to the position and a signal is sent;

[0079] The workbench clamping device releases the workbench, the positioning piston rod in the workbench positioning device moves downward, the positioning detection block moves to the first detection switch position, the first detection switch position detects the positioning detection block, and determines that the workbench is in a non-clamped state;

[0080] Move the worktable out of the base plate to clamp the next workpiece.

[0081] In the process of positioning, clamping and flipping, the detection device of this embodiment detects whether each action is in place. Only after the action is in place will the next action be carried out, thereby avoiding the accumulation of errors, improving the processing accuracy, and realizing the exchange method of a machining center for multiple workbenches, thereby improving the overall production efficiency.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
