Referring to fig. 1, according to an aspect of the embodiment of the present invention, there is provided a cutting machine 100, including: the cutting machine includes a base 110, a jig assembly 120 disposed on the base 110, a lifting device 130 slidably disposed along a mounting surface of the base 110, and a cutting assembly 140 coupled to the lifting device 130, the lifting device 130 being used to move the cutting assembly 140 toward or away from the base 110.

The base 110 may be provided as a frame structure formed by welding or screwing a plurality of profiles, and a plurality of reinforcing ribs may be provided in the frame structure in order to increase the strength of the entire base 110. Further, a plurality of guide rails 111 are provided on the base 110 in parallel with each other.

The cutting machine 100 further includes a moving frame 150, the moving frame 150 is provided with a slider 151 matched with the guide rail 111, and the moving frame 150 can move along the X-axis of the guide rail 111 through the slider 151, in order to make the moving frame 150 move more smoothly, as shown in fig. 1, at least four guide rails 111 can be provided on the base 110, wherein two guide rails 111 are located on the top surface of the base 110, and the other two guide rails 111 are located on two opposite or opposite side surfaces of the base 110.

The lifting device 130 is movably disposed on the movable frame 150, and specifically, a lead screw (not shown) is disposed on the movable frame 150, and a nut is rotatably connected to the lifting device 130, and the lead screw is driven by an external force to rotate so as to drive the lifting device 130 to move along the movable frame 150, that is, along the Y-axis of the base 110.

The structural form of the lifting device 130 in the embodiment of the present invention is not particularly limited, and for example, the lifting device may be configured as a lifting cylinder, and may also be configured as a motor to drive a gear rack structure to achieve a lifting function.

When the cutting machine 100 according to the embodiment of the present invention is used, a workpiece to be processed is first placed on the fixture assembly 120 and clamped, and then the cutting machine 100 is started, so that the lifting device 130 drives the cutting assembly 140 to move to a processing position, and the cutting assembly is started to process the workpiece to be processed.

According to the cutting machine 100 provided by the embodiment of the invention, the fixture assembly 120 is arranged on the base 110, so that when a workpiece to be machined is machined, the workpiece to be machined can be clamped on the base 110 through the fixture assembly 120; the cutting assembly 140 is arranged on the lifting device 130 by slidably arranging the lifting device 130 on the base 110, so that the cutting assembly 140 can be driven to move by the movement of the lifting device 130 on the base 110 during the machining process or when the machining position needs to be changed; the cutting assembly 140 is driven to ascend and descend by the ascending and descending device 130, so that the position of the cutting assembly 140 can be lifted by the ascending and descending device 130 in the moving process, and unnecessary cutting processing for the workpiece to be processed is avoided due to the fact that the position of the cutting assembly 140 is highly moved in the processing position. Since the cutting assembly 140 moves along the base 110 in the machining direction while machining the workpiece to be machined during machining, machining accuracy is high.

Alternatively, referring to fig. 1, the cutting assembly 140 includes a fixing portion 141 connected to the lifting device 130, a rotating portion 142 rotatably disposed on the fixing portion 141, and a cutting tool 143 disposed on the rotating portion 142, wherein a rotation axis of the rotating portion 142 is perpendicular to the mounting surface of the base 110.

First, the lifting device 130 can lift the fixing portion 141, and further lift the rotating portion 142 disposed on the fixing portion 141 and the cutting tool 143 connected to the rotating portion 142.

Second, since the cutting tool 143 is generally machined during rapid rotation of the rotary motor, the cutting tool 143 is generally rotatably provided on the rotating portion 142, and the rotation is rotation of the cutting tool 143.

With the above-described structure, the machining direction of the cutting tool 143 can be changed, and after the member to be machined is clamped to the base 110, the operation of cutting the member to be machined can be performed along the X-axis, the Y-axis, and any one direction between the X-axis and the Y-axis of the member to be machined. For example, when the workpiece to be processed is a curved arc-shaped profile, and it is necessary to cut a tear at both ends of the curved arc-shaped profile, the cutting tool 143 may be used to perform a cutting tear at one end of the curved arc-shaped profile, and then the cutting tool 143 is moved to the other end of the curved arc-shaped profile, and the cutting tool 143 is rotated to the direction in which the tear is to be cut at the other end to perform a cutting tear operation.

Optionally, referring to fig. 2, a rotation driving device 144 is fixedly connected to the fixing portion 141, and the rotation driving device 144 is in transmission connection with the rotating portion 142 to drive the rotating portion 142 to rotate.

The rotary drive 144 may be provided as a motor. On the basis, a motor shaft can be used to connect with the rotating part 142, and the rotating part 142 is directly driven by the motor to rotate; since the output torque of the motor is small and the rotation speed is high, referring to fig. 3, a gear set 145 may be disposed between the motor and the rotating portion 142, and the power of the motor may be transmitted to the rotating portion 142 through the gear set 145, so that the rotating portion 142 may obtain a large torque and a small rotation speed.

Optionally, referring to fig. 1, the cutting assembly 140 includes a plurality of cutting assemblies 140, and the plurality of cutting assemblies 140 are commonly connected to the lifting device 130.

Thus, the cutting machine 100 of the embodiment has higher working efficiency, and can process a plurality of positions of a workpiece to be processed at the same time; furthermore, by providing the cutting tool 143 as a different tool, different machining methods can be performed on the workpiece to be machined at the same time.

Optionally, referring to FIG. 2, cutting assembly 140 further includes an angled drill chuck 147 drivingly connected to cutting tool 143.

It should be noted that the cutting tool 143 may be configured as a saw blade, specifically, the saw blade is connected to the rotating portion 142, and the rotating motor drives the saw blade to rotate to perform operations such as cutting, segmenting or tearing on the workpiece; the cutting tool 143 may also be configured as a milling cutter, which is mounted by an angled drill chuck 147 and driven by a rotary motor via the angled drill chuck 147 to perform hole machining on the inner side of the arc-shaped workpiece to be machined. Thus, the cutting machine 100 of the present embodiment can perform different processing methods.

Optionally, referring to fig. 4 and 5, the cutting machine 100 according to the embodiment of the present invention further includes a locking device 148 connected to the fixing portion 141, wherein the locking device 148 is used for locking the rotation angle of the rotating portion 142.

It should be noted that the locking device 148 is mainly used for locking the rotation angle of the rotating portion 142 during the process of machining the workpiece to be machined by the cutting tool 143. Since the cutting tool 143 receives the reaction force from the workpiece to be machined in the process of machining the workpiece to be machined by the cutting machine 100 of this embodiment, the cutting tool 143 is also subjected to the reaction force from the workpiece to be machined, and thus by providing the locking device 148, the cutting tool 143 is more stable in the process of machining the workpiece to be machined, and the situation that the machining precision is affected and even the rotary driving device 144 is damaged due to the rotation around the rotating portion 142 caused by the reaction force is reduced.

Optionally, referring to fig. 5, the locking device 148 includes a linear driving device 241 disposed on the fixing portion 141 and a locking member 242 connected to the linear driving device 241, and the rotating portion 142 is provided with a plurality of grooves 149 matched with the locking member 242, so that the locking member 242 can move under the driving of the linear driving device 241 and can be locked into the grooves 149.

In particular, the linear driving device 241 may be configured to drive a cylinder or a hydraulic cylinder. The retaining member 242 may be configured as a cylindrical pin, and in order to make it easier for the retaining member 242 to extend into and engage the groove 149, the diameter of the end of the retaining member 242 facing the groove 149 may be smaller than the diameter of the end facing away from the groove 149, and correspondingly, the shape and size of the groove 149 may be matched to the retaining member 242. To further reduce the rotation of the cutting tool 143 when subjected to a reaction force, the locking member 242 and the recess 149 may be provided as an interference fit.

Optionally, referring to fig. 6, the clamping apparatus assembly 120 includes a first clamping apparatus 121 and a second clamping apparatus 123 respectively disposed on the base 110, the first clamping apparatus 121 includes a first clamping surface 122, the second clamping apparatus 123 includes a second clamping surface 124, and an included angle is formed between the first clamping surface 122 and the second clamping surface 124.

Specifically, the first clamp 121 includes a fixed plate 125 fixedly connected to the base 110 and a movable plate 126 slidably connected to the base 110, which are oppositely disposed, and the movable plate 126 may be driven by a clamp cylinder 127, so long as the movable plate 126 can be moved to the movable plate 126 and the fixed plate 125 by an external force to clamp the workpiece to be processed, and the second clamp 123 may be configured in the same structure as the first clamp 121.

Thus, for the nonlinear workpiece to be machined, the workpiece to be machined can be better clamped on the base 110 through the first clamp 121 and the second clamp 123, and the situations that the machining precision is influenced and the cutting tool 143 is more seriously abraded due to large deformation generated when the workpiece to be machined is subjected to the cutting force of the cutting tool 143 because the clamping position of the workpiece to be machined on the base 110 is less are reduced.

Optionally, referring to fig. 6, the clamping apparatus assembly 120 further includes a third clamping apparatus 128 disposed on the base 110 and located between the first clamping apparatus 121 and the second clamping apparatus 123, where the third clamping apparatus 128 includes a third clamping surface 129, and the third clamping surface 129 is an arc surface.

In this way, for the workpiece to be machined in the curved shape, the workpiece can be clamped on the base 110 by the first clamp 121, the third clamp 128 and the second clamp 123 together, so that the machining precision of the cutting machine 100 of the embodiment is higher.

Alternatively, referring to fig. 6, each fixture assembly 120 includes a plurality of first fixtures 121, the plurality of first fixtures 121 are slidably arranged along the mounting surface, each fixture assembly 120 includes a plurality of second fixtures 123, and the plurality of second fixtures 123 are slidably arranged along the mounting surface.

Therefore, when the fixture assembly 120 is used for clamping the workpiece to be processed, the position of the fixture assembly 120 can be correspondingly adjusted according to the length of the workpiece to be processed, so that the clamping of the workpiece to be processed is more stable.

Alternatively, referring to fig. 1, the chucking assembly 120 includes a plurality of chucking assemblies 120, and the plurality of chucking assemblies 120 are disposed on the base 110 in the same arrangement direction.

Therefore, a plurality of workpieces to be machined can be clamped on the base 110, and when the workpieces to be machined are clamped on one clamping device assembly 120, the workpieces to be machined clamped on the other clamping device assemblies 120 can be disassembled and assembled.

Specifically, when the linear type workpiece to be machined is machined by using the cutting machine 100 of the present embodiment, the machining dimension can be calculated by abutting one end of the linear type workpiece to be machined on the positioning portion 112 and clamping the linear type workpiece to be machined by the jig assembly 120, with the positioning portion 112 as an origin, so that the positioning of the linear type workpiece to be machined on the base 110 is more accurate.
