Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing, in particular to a sawing tool. Background Art

[0002] Sawing refers to the process of processing workpieces with serrated tools (such as saw blades, circular saw blades, saw bands) or thin grinding wheels. Sawing specifically includes operations such as splitting, cutting, and sawing grooves on the workpiece. It is widely used in the equipment manufacturing industry, the automotive industry, and the construction industry. The three most commonly used sawing methods in the prior art are as follows: Method 1, workers hold serrated tools in their hands to saw the placed workpiece; Method 2, manually hold the workpiece and bring the workpiece close to the power-driven sawing tool to saw the workpiece; Method 3, two workers work together, one worker fixes the workpiece, and the other worker uses a manual sawing tool to saw the workpiece. However, since the manual participation in sawing is inefficient, time-consuming and labor-intensive, and the serrated tools are sharp, the sawing process is extremely dangerous.

[0003] In order to solve the above technical problems, a Chinese utility model patent with patent number ZL202020127012.1 (authorization announcement number CN211682396U) discloses a plastic product pressing and sawing device, which includes a supporting mechanism, a control mechanism, a pressing mechanism and a sawing mechanism. The device presses the plastic product on the pad through the pressing mechanism, and then the plastic product on the pad is sawed by rotating the sawing mechanism. Therefore, the device does not require manual participation in the sawing process, reduces the risk, and improves production efficiency.

[0004] However, the above device is not suitable for Figure 1 In the case shown, the workpiece 1 to be sawed in this case includes a first body 11 and a second body 12 formed by extending outward along the edge of the first body 11, and the junction 13 between the second body 12 and the first body 11 is the position to be sawed; Figure 1 As shown in the figure, the first body 11 is a box body with a receiving space and an open top, and the second body 12 is formed outward along the top edge of the box body; since the sawing mechanism in the above device is arranged on one side of the clamping mechanism, and the saw blade of the sawing mechanism is always kept in a vertically arranged state, if the above device is directly used, it is not easy to saw the non-vertical position to be sawed, such as Figure 1The position to be sawed is horizontal, so the above device is not suitable for sawing the workpiece to be sawed in this situation; in addition, since the first body 11 and the second body 12 will be separated after the sawing of the above workpiece 1 to be sawed, and the method of pressing the workpiece to be sawed by a push rod in the above device can only press one of the bodies, and the other body will easily shift after sawing, so it is difficult to maintain the stability of sawing. Therefore, it is necessary to further improve the existing technology. Utility Model Content

Preferably, the first clamping mechanism also includes a first frame for installing a first clamping head, and the first frame is provided with a first driving source for driving the first clamping head to clamp or loosen the first body. When the first clamping head clamps the first body of the workpiece to be sawed, the first clamping head abuts against the upper wall surface of the first body of the workpiece to be sawed.

[0015] In order to enable the first clamping head to clamp a position at a farther distance, preferably, the first clamping head includes at least one sub-clamping head bent and extended toward the first main body, the sub-clamping heads are connected in sequence, and the sub-clamping head located at the head of the first clamping head is gradually bent from top to bottom.

[0016] There are many kinds of structures of the second clamping mechanism. Preferably, the second clamping mechanism further comprises a second frame for mounting a second clamping head, and the second frame is provided with a second driving source for driving the second clamping head to clamp or release the second body.

[0017] In order to prevent the workpiece from deforming when being pressed, the second frame is also provided with a support block located below the second pressing head. The support block and the second pressing head jointly limit an installation space for installing the second body of the workpiece to be sawed. The support block abuts against the lower wall surface of the second body of the workpiece to be sawed. When the second pressing head presses the second body of the workpiece to be sawed, the second pressing head abuts against the upper wall surface of the second body of the workpiece to be sawed.

[0018] In order to ensure that the installation of the workpiece to be sawed is more stable and to prevent displacement during the sawing process, the clamping mechanism also includes a third clamping mechanism for clamping the first main body outer peripheral wall of the workpiece to be sawed when the workpiece to be sawed is installed. The third clamping mechanism includes a plurality of third clamping heads, each of which is arranged on the periphery of the workpiece to be sawed and encloses a positioning area that can be adapted to the outer peripheral wall of the workpiece to be sawed.

[0019] There are many kinds of structures of the third clamping mechanism. Preferably, the third clamping mechanism further includes a third frame for mounting a third clamping head, and the third frame is provided with a third driving source for driving the third clamping head to clamp or release the second body.

[0020] In order to make the clamping range of the third clamping head wider, the third clamping head is in the shape of an elongated strip, and a plurality of bosses are arranged on the third clamping head at intervals along its length direction. Each boss simultaneously clamps or loosens the outer wall of the second body under the action of the third driving source.

[0021] In order to avoid the influence of dust during the sawing process and to cool down the sawing tool to prevent the sawing temperature from being too high, the front end of the robot's mechanical arm is also provided with a blowing device arranged near the sawing tool, which can blow away the dust generated by the sawing tool during the sawing process and / or cool down the heat generated by the sawing tool during the sawing process.

[0022] Preferably, the sawing tool comprises a saw blade which is arranged on a driving motor and drivingly connected to a power output shaft of the driving motor.

[0023] Compared with the prior art, the advantages of the utility model are: on the one hand, the first body of the workpiece to be sawed is clamped by the first clamping mechanism, and the second body of the workpiece to be sawed is clamped by the second clamping mechanism, so that the stability of the first body and the second body during the sawing process is always guaranteed, and the sawing instability problem caused by the displacement of one of the bodies after sawing can be effectively prevented; on the other hand, the robot's mechanical arm moves according to the connection position of the first body and the second body, thereby improving the sawing efficiency and enhancing safety.
