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 machining a workpiece using sawing tools such as serrated cutters or thin grinding wheels. Traditional sawing work mostly involves manually supporting the workpiece and then using sawing tools to perform corresponding cutting operations on the workpiece. However, the manual sawing work method is inefficient, time-consuming and labor-intensive, and the sawing tools are relatively sharp, which makes the manual sawing process extremely dangerous. Therefore, sawing tools are commonly used to solve the above technical problems.

[0003] Existing sawing tools, such as the Chinese utility model "A circular saw cutting device for automobile stamping parts" with patent number ZL202322264258.X (authorization announcement number CN220717948U), include a base, a saw blade, a supporting device and a driving device. The supporting device includes a workbench arranged on the base, and a plurality of groups of electric cylinders and a plurality of groups of clamps are provided on the base. The plurality of groups of clamps are respectively installed on the plurality of groups of electric cylinders. When the stamping parts are placed on the workbench, the plurality of groups of clamps are pushed to move by the plurality of groups of electric cylinders so that the plurality of groups of clamps clamp the stamping parts and fix them. The saw blade is then driven to rotate horizontally by the driving device, thereby adjusting the rotation angle of the saw blade, and then facilitating the saw blade to cut the stamping parts at different angles.

[0004] Although the above-mentioned sawing tool can cut the workpiece at different angles, it is not suitable for workpieces with a long length and a special sawing position, such as Figure 1 The workpiece shown, the workpiece to be sawed 1' comprises a main body 11' in the shape of a long strip, a first piece to be cut 12' extending outward along the horizontal length direction of the main body 11', and a second piece to be cut 13' arranged in the center of the main body 11'. The thickness of the main body 11' is relatively thin, and the connection between the main body 11' and the first piece to be cut 12' and the connection between the main body 11' and the second piece to be cut 13' are both positions to be sawed. If the workpiece to be sawed 1' is installed in the above-mentioned sawing tool, the multiple groups of clamps can only clamp the two opposite sides of the workpiece to be sawed 1', that is, the workpiece to be sawed 1' can only be positioned from one direction, so that the workpiece to be sawed 1' will still be loose in the other directions, and the workpiece to be sawed 1' cannot be stably fixed on the workbench, and the sawing tool cannot be aligned with the position to be sawed. In addition, since the main body 11' of the workpiece 1' to be sawed is relatively long and thin, the sawing tool may cause a certain deformation of the periphery or the central periphery of the main body 11' when cutting the first workpiece 12' or the second workpiece 13' to be cut, thereby affecting the sawing effect of the sawing tool, resulting in poor quality of the workpiece after sawing. For this reason, further improvements are made to the sawing tool. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a sawing tool capable of more stably processing a workpiece to be processed in view of the above-mentioned existing technical status, and is particularly suitable for workpieces with a long length and special requirements for the sawing position.

[0007] It is characterized in that: the working platform is provided with

[0008] A first support portion is used to support the main body so that the main body maintains a preset distance relative to the working platform; a stopper is provided on the first support portion, and the stopper can abut against the outer peripheral wall of the main body, thereby limiting the horizontal movement of the main body;

[0009] A clamping mechanism, having at least two, arranged at intervals along the periphery of the workpiece to be sawed, used to clamp the main body placed on the first support portion to limit the main body from moving vertically, wherein a part of the clamping mechanism cooperates with the first support portion to position the main body and form a processing area adapted to the shape of the second workpiece to be sawed, and the remaining part of the clamping mechanism is arranged at intervals along the horizontal length direction of the main body and divides the first workpiece to be sawed into a plurality of sawing areas;

[0010] The sawing mechanism is used to saw the compressed workpiece to be sawed. The sawing mechanism includes a robot and a sawing tool arranged at the front end of the robot's mechanical arm. The robot's mechanical arm performs corresponding actions according to the first workpiece to be cut in the sawing area and the second workpiece to be cut in the processing area to control the sawing direction of the sawing tool.

The first piece to be cut is formed by extending along the horizontal length direction of the main body. Therefore, the length of the first piece to be cut is relatively long. During the process of processing the workpiece to be sawed, the first piece to be cut is easy to cause the main body to deform. The present application uses a plurality of second support parts supporting the first piece to be cut, so that the first piece to be cut can be placed on the work platform more stably, thereby avoiding deformation of the main body caused by cutting the first piece to be cut.

The clamping head of the clamping mechanism is rotatably mounted on the frame, and the clamping head is manually rotated to rotate relative to the frame, thereby clamping or loosening the main body.

[0017] Compared with the prior art, the advantages of the utility model are:

[0018] 1. The sawing tool supports the main body of the workpiece to be sawed by the first supporting part, and the stopper on the first supporting part presses against the outer peripheral wall of the main body, thereby limiting the horizontal movement of the main body; and the cooperation between the first supporting part and a part of the clamping mechanism can not only clamp the main body, but also form a processing area for the sawing mechanism to process the second workpiece to be cut, so that when the sawing mechanism saws the second workpiece to be cut, the main body positioned by the first supporting part and the clamping mechanism will not be deformed, and thus the sawing tool meets the needs of workpieces with special requirements for the sawing position;
