[0031] The present disclosure will be described below with reference to the drawings, in which several embodiments of the present disclosure are shown. However, it should be understood that the present disclosure can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present disclosure more complete and fully explain the protection scope of the present disclosure to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.

[0032] It should be understood that the terms used in the specification are only for describing specific embodiments and are not intended to limit the present disclosure. All terms used in the specification (including technical terms and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0033] The singular forms “a,” “the,” and “said” used in the specification include the plural forms unless clearly specified otherwise. The terms “comprising,” “including,” and “having” used in the specification mean the presence of the claimed features, but do not preclude the presence of one or more other features. The term “and / or” used in the specification includes any and all combinations of one or more of the associated listed items. The terms “between X and Y” and “between approximately X and Y” used in the specification should be interpreted to include X and Y. The term “between approximately X and Y” used in this specification means “between approximately X and approximately Y,” and the term “from approximately X to Y” used in this specification means “from approximately X to approximately Y.”

[0034] In the specification, when it is stated that an element is “on,” “attached” to, “connected” to, “coupled” to, or “in contact” with another element, etc., the element can be directly on, attached to, connected to, coupled to, or in contact with the other element, or there can be an intermediate element. In contrast, when it is stated that an element is “directly” on, “directly attached” to, “directly connected” to, “directly coupled” to, or “directly in contact” with another element, there will be no intermediate element. In the specification, a feature being arranged “adjacent” to another feature can mean that the feature has a portion overlapping with the adjacent feature or a portion located above or below the adjacent feature.

It should be understood that the spatial relationship terms include different orientations of the device during use or operation in addition to the orientations shown in the drawings. For example, when the device in the drawing is inverted, a feature originally described as “below” other features can then be described as “above” the other features. The device can also be oriented in other ways (rotated 90 degrees or in other orientations), and the relative spatial relationships will be interpreted accordingly at this time.

[0036] As Figures 1-4 shown, the present disclosure provides a sawing machine. More specifically, a vertical sawing machine. The sawing machine includes a saw blade and is capable of performing cutting by means of the saw blade. Specifically, the saw blade performs cutting by moving rapidly in the up-and-down direction in the figure.

[0037] The sawing machine includes a sawing machine main body 101, and the sawing machine main body 101 is in the shape of a cube with a hollow middle part. The middle part is an operating part for clamping and cutting workpieces, and the table 105, clamping mechanism, and moving mechanism to be described later are all arranged at the middle part.

[0038] The sawing machine may further include a driving mechanism (not shown) configured to drive the saw blade to move up and down at high speed, and a control device (not shown) for controlling the operation of the driving mechanism (such as starting, stopping, pausing, accelerating, or decelerating). The driving mechanism and the control device may be provided in the upper part and the lower part of the sawing machine. The control device may include one or more of a host computer with a human-machine interface (HMI), a lower computer with a programmable logic controller (PLC controller), a D / A conversion module, an inverter, a main motor, a power sensor, a rotary encoder, and a reduction gear. In this embodiment, the driving mechanism includes four driving wheels, and the four driving wheels are fixed to the upper part of the sawing machine through a suspension. The four driving wheels are oppositely arranged along the length direction (i.e., the second direction) of the sawing machine, and the saw blade is clamped therein, and the saw blade is driven to move up and down by the rotation of the four driving wheels. It should be understood that the driving wheels may also be arranged inside the upper part and the lower part of the sawing machine.

[0039] The sawing machine further includes a table 105. The table 105 is arranged at a generally middle position in the height direction of the sawing machine. The table 105 is provided with a slit penetrating in the height direction along the width direction (i.e., the first direction) of the sawing machine, and the size of the slit is set such that the saw blade can pass through it. In this embodiment, the slit is arranged at a generally middle part of the table 105 along the length direction. The saw blade extends through the slit and performs cutting by moving up and down.

[0040] In this embodiment, the table 105 is configured to be movable relative to the sawing machine main body 101 in the width direction through a first moving mechanism. Thus, the workpiece to be cut fixed to the table 105 can move relative to the saw blade in the width direction, so that the workpiece can be completely cut. The first moving mechanism is configured as a slider and slideway structure that cooperate with each other. It should be understood that the first moving mechanism may also adopt other forms, such as screw movement, as long as it can make the table 105 move relative to the sawing machine main body 101. The same applies to the second moving mechanism described later.

[0041] Refer to Figure 4, in this embodiment, the first moving mechanism includes a first table slider 110 disposed on the table surface and a main body slideway 107 disposed on the sawing machine main body. The first table slider 110 is disposed on the lower surface of the table surface 105. The table slider 110 extends in the width direction. The first table sliders 110 can be arranged in pairs in the length direction, so that the movement of the table surface is smoother. The main body slideway 107 can be disposed on the surface of the sawing machine main body facing the lower surface of the table surface. The main body slideway 107 is configured to slidably engage with the first table slider 110 so that the first table slider 110 can move along the main body slideway. In this embodiment, the main body slideway 107 is disposed on the connecting plate 108, and the connecting plate 108 can be configured to be detachably fixed to the sawing machine main body. Further, a slideway can be directly disposed on the connecting plate, or the slideway is disposed on a plurality of scattered blocks fixed to the connecting plate.

[0042] It should be understood that the positions of the slideway and the slider can be interchanged, that is, the first moving mechanism includes a slideway disposed on the table surface and a slider disposed on the sawing machine main body.

[0043] The sawing machine further includes a fixture 102. The fixture 102 is configured to clamp the workpiece to be cut. The fixture is disposed on the table surface 105 and can move relative to the table surface along a second direction through a second moving mechanism. As Figure 1 shown, the fixture 102 adopts a universal fixture.

[0044] As Figure 1 shown, the second moving mechanism includes a second table slideway disposed on the table surface and a fixture slider disposed on the fixture. In this embodiment, the second table slideway is disposed on the fixture connecting plate 104. It should be understood that the second table slideway can be directly disposed on the upper surface of the table surface. The second table slideways are oppositely disposed in the width direction. The second table slideway extends in the length direction. The fixture slider is disposed on the lower surface of the fixture 102. The fixture slider is configured to slidably engage with the second table slideway so that the fixture 104 can move along the second table slideway. In this embodiment, the fixture connecting plate 104 can be configured to be detachably fixed to the table surface 105.

[0045] It should be understood that the positions of the slideway and the slider can be interchanged, that is, the second moving mechanism includes a slider disposed on the table surface and a slideway disposed on the fixture.

[0046] Through the second moving mechanism, the position adjustment of the workpiece clamped by the fixture 102 in the length direction can be realized, so that the part to be cut can be adjusted.

[0047] In this embodiment, both the first moving mechanism and the second moving mechanism adopt a structure in which a slideway and a slider cooperate, and by respectively arranging slideways relative to the fixture and relative to the sawing machine main body on the upper and lower surfaces of the table 105, the size of the entire moving mechanism in the height direction is very small or very compact. In other words, by respectively arranging slideways and sliders on the upper and lower surfaces of the table 105, and thus constructing the distance between the main slideway and the fixture slider cooperating therewith in the height direction to be very small, the main slideway and the fixture slider are only spaced apart by the thickness of the table (optionally also including, for example, a fixture connecting plate, etc.) in the height direction.

[0048] The sawing machine further includes handrails 103, and the handrails 103 are arranged in pairs on the upper surface of the table near one end of the table 105 along the length direction. Through the handrails, the operator can push the table 105 and the workpiece clamped on the table 105 to move at a relatively long distance from the saw blade, improving the safety of operation. It should be understood that an automatic moving mechanism, such as a cylinder or the like, can also be provided, and the automatic movement of the table 105 is controlled by a control device.

[0049] As Figures 1-3 shown, the sawing machine further includes limit members 106. The limit members 106 are fixedly arranged on the lower surface of the table 105 and are arranged oppositely along the width direction. In this embodiment, the limit members 106 are also arranged oppositely along the length direction, that is, four limit members are arranged. The limit members 106 are configured to prevent the table 105 from moving too far back and forth along the width direction. In this embodiment, this is achieved through the cooperation of the limit members 106 and the connecting plate 108. Specifically, the connecting plate 108 is arranged between the opposite limit members 106 along the width direction and coincides with the limit members 106 in the height direction. Therefore, when the table 105 moves too far back and forth along the width direction, it will abut against the connecting plate 108. The sawing machine further includes a buffer member 109, and the buffer member 109 is fixed to the limit member 108 and is located between the fixed limit member 108 and the connecting plate along the width direction. The buffer member 109 can be a rubber pad, so that the impact with the connecting plate 108 can be buffered.

[0050] As Figure 4 shown, by arranging the limit mechanism as above, the size of the operation part of the entire sawing machine is very small. More specifically, the size in the height direction is very small. The manual operation part or the visible operation part of the entire sawing machine is shrunk into the limited distance between the upper and lower surfaces of the table 105, and various components are arranged around the upper and lower surfaces of the table 105, realizing the size compression in the height direction. In addition, by using the connecting plate 108 not only as the first moving mechanism but also as the limit mechanism, the number of components is also reduced.

[0051] Therefore, the present utility model provides a sawing machine, which is not only simple and effective in structure, safe in operation, but also relatively small in overall size, especially the size in the height direction is effectively compressed.

[0052] Although some specific embodiments of the present disclosure have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present disclosure. The various embodiments of this utility model can be combined arbitrarily without departing from the spirit and scope of the present disclosure. Those skilled in the art should also understand that various modifications can be made to the embodiments without departing from the scope and spirit of the present disclosure. The scope of the present disclosure is defined by the appended claims.
