[0041] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0042] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0043] Example 1

[0044] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides a processing machine tool, including:

[0045] The clamp assembly 10, such as Figure 3 As shown, a plurality of clamps 12 for clamping a workpiece 11 are arranged along a first direction;

[0046] Two sets of processing components are respectively located on two sides of the fixture component 10 along the first direction;

[0047] At least two groups of machining spindles 21 are arranged along the second direction on the machining assembly, and the feeding direction of the tool in the machining spindle 21 is the third direction; the machining spindles 21 of the two groups of machining assemblies 20 are arranged facing each other; the arrangement direction of the spindles in each group of the machining spindles 21 is parallel to the first direction;

[0048] The first direction, the second direction and the third direction are perpendicular to each other.

[0049] like Figure 2 As shown, the first direction is Figure 2 The first direction is the X direction, the second direction is the Z direction, and the third direction is the Y direction;

[0050] Among them, in this embodiment, the number of fixtures 12 in the fixture assembly is 6, which can be used to clamp 6 workpieces 11. The machinable workpiece 11 is, for example, a refrigerator compressor crankshaft, which requires different tools such as milling cutters, drills, and turning tools during processing; the milling cutter, drill bit, and turning tool can be installed separately on multiple processing spindles arranged in the second direction; after completing the processing of the milling cutter, by moving the position of the processing spindles arranged in the second direction so that the current processing tool is aligned with the workpiece, the processing of the next step can be immediately started without replacing the clamped workpiece again.

[0051] Among them, the fixture 11 in this embodiment is a displacement fixture, specifically,

[0052] The clamp assembly 10 comprises:

[0053] A clamp seat 13, used for fixing the clamp 12;

[0054] Two connecting plates 14 are respectively fixed at two ends of the clamp seat 13 along the first direction;

[0055] The flipping driving mechanism 15 is used to drive the connecting plate to rotate so as to flip the clamp seat 13 ; the rotation axis of the connecting plate 14 is parallel to the first direction.

[0056] Specifically, the connecting plate 14 is an L-shaped plate, and the two ends of the fixture seat 13 are supported by two L-shaped plates arranged opposite to each other and fixed with bolts; the flip driving mechanism 15 is a flip servo motor, and the main shaft of the flip servo motor is fixedly connected to the center of any one of the connecting plates 14, and the connecting plate 14 is driven to rotate around its central axis parallel to the first direction, thereby driving the fixture seat 13 to rotate. The other connecting plate 14 is rotatably mounted on the machine tool along the first direction.

[0057] For example, if both ends of a workpiece need to be processed with a drill and a milling cutter, the two ends of the workpiece can be flipped by simply turning the fixture seat without changing the processing tools, which greatly improves convenience.

[0058] Preferably, in this embodiment, a mechanical claw 22 is installed in the processing spindle for clamping and turning the workpiece. Only one row of processing spindles for installing the mechanical claw 22 is required, and the other processing spindles are still used to install the processing tools 23;

[0059] The fixture seat 13 is provided with a plurality of workpiece clamping positions arranged along a first direction; Figure 3 and Figure 4 As shown, each of the workpiece clamping positions is provided with:

[0060] Features:

[0061] A placement slot for placing workpieces;

[0062] The pressing member 13 - 1 , whose pressing force is provided by the oil cylinder 132 , is used to press the workpiece 11 into the groove; the oil cylinder 13 - 2 is fixed on the fixture seat 13 .

[0063] In this embodiment, if Figure 4As shown, the oil cylinder 13-2 is a customized dual-circuit oil cylinder having two pistons 13-3 extending in parallel in the same direction, and the pressing pieces 13-1 on the two adjacent clamping positions are respectively fixed on the two piston rods 13-3; the oil circuit 13-4 for supplying oil to the oil cylinder 13-2 is arranged in the clamp seat 13, and the pressing force of the pressing piece 13-1 is adjusted by adjusting the oil supply amount, thereby achieving clamping or loosening of the workpiece 11.

[0064] In other embodiments, Figure 5 As shown, the cylinder 13-2 can also be an ordinary single-way cylinder, the end of its piston rod 13-3 is connected to a connecting piece 13-5, and the pressing pieces 13-1 on two adjacent clamping positions are located at both ends of the connecting piece 13-5. The device is provided with an oil circuit distributor to supply oil to each cylinder; the pressing force of the pressing piece 13-1 is adjusted by adjusting the amount of oil supply, thereby clamping or loosening the workpiece 11, and the support piece 13-6 used to fix the cylinder 13-2 on the fixture seat 13 is arranged through the connecting piece 13-5.

[0065] In this embodiment, before the control module of the machine tool starts the movement of the machine tool spindle equipped with the mechanical claw 22 to flip the workpiece, the pressure of the oil cylinder 13-2 of the pressing member 13-1 is reduced to zero. That is, when processing the workpiece, the control module refuels the oil circuit of the oil cylinder so that its pressure reaches the maximum value to clamp the workpiece; when the workpiece needs to be flipped by the mechanical claw 22, the control module unloads the oil circuit of the oil cylinder so that the clamping pressure of the pressing member 13-1 on the workpiece is reduced to 0, thereby causing the workpiece 11 to rotate under the rotation drive of the mechanical claw.

[0066] In this embodiment, the clamp assembly can slide along the first direction to align the processing position of the workpiece with the tool in the processing spindle; the processing assembly can slide along the third direction to adjust the distance between the processing tool and the workpiece to suit the processing of workpieces of different lengths; the processing assembly can slide along the second direction to replace different processing spindles. Since different tools are installed on different rows of processing spindles, the replacement of different processing tools is realized at this time, and different processing processes can be realized without changing the workpiece.

[0069] The base 30 is provided with a Y-axis slide rail 36 parallel to the third direction, and the slide 32 can be slidably mounted on the base 30 along the third direction. The base 30 is provided with a second drive mechanism 37 for driving the slide 32 to slide. The second drive mechanism 37 is a servo motor. The second drive mechanism 37 is coaxially connected with a lead screw arranged parallel to the third direction. The lead screw is threadedly connected to the slide 32. The second drive mechanism 37 drives the lead screw to rotate, driving the slide 32 to slide along the third direction, thereby adjusting the distance between the machining spindle and the fixture assembly, that is, adjusting the distance between the tool and the workpiece, so as to be suitable for machining workpieces of different lengths, and machining different parts of the workpiece in the third direction. In this embodiment, the slides 32 of the two fixture assemblies share a slide rail.
