[0002] In the modern processing field, sawing machines have become an indispensable part. Sawing, as the starting point of precision cutting, has become an important component in the parts processing process. Sawing can save materials, reduce the amount of secondary processing and improve production efficiency.

[0003] After searching, the utility model with Chinese patent announcement number CN213034812U discloses a positioning fixture structure for a sawing machine, including a workbench, an electric saw and a U-shaped clamp. A slide groove is opened in the middle position of the workbench, and a slider is slidably placed in the slide groove. One end of the workbench is located on both sides of the slide groove and three rectangular grooves A and three rectangular grooves B are equidistantly opened, wherein light columns A and light columns B are installed in the rectangular grooves A and the rectangular grooves B on both sides of the three rectangular grooves A and B.

[0004] The above device achieves the purpose of clamping by squeezing the two ends of the workpiece with two clamping plates. However, when clamping a relatively soft workpiece, excessive clamping force will cause the material to deform, and even cause the material to break away from the clamp due to force during cutting.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 2 and Figure 3 As shown, in this embodiment, a clamp for a sawing machine includes a bed body 1 and a mounting frame 2, characterized in that: a clamping assembly 4 is installed in the mounting frame 2, the clamping assembly 4 includes the same bidirectional screw rod 401 that is rotatably connected to the inner walls on both sides of the mounting frame 2, both ends of the bidirectional screw rod 401 are threadedly connected to a mounting block 403, the two mounting blocks 403 are slidably inserted with the same limit rod 402, the two ends of the limit rod 402 are respectively fixedly connected to the inner walls on both sides of the mounting frame 2, the top outer walls of the two mounting blocks 403 are fixedly connected to a sliding frame 404, the bottoms of the two sliding frames 404 are slidably connected to a splint 405, and the bottom positions of the two splints 405 are provided with a plurality of through holes with equal distances, and the outer wall on one side of the mounting frame 2 is rotatably connected to a handle 406, and the handle 406 is coaxially fixed with the bidirectional screw rod 401.

[0024] By rotating the handle 406 on one side of the mounting frame 2, the handle 406 drives a bidirectional screw 401 to rotate, and the two mounting blocks 403 will be restricted by the limit rod 402 and driven by the bidirectional screw 401, and the two mounting blocks 403 will be translated closer to each other, and then the position of the sliding frame 404 and the clamping plate 405 therein will also change accordingly, and the workpiece will be fixed by the two clamping plates 405. If fixed in this way, when the workpiece is cut, the saw blade will directly pass through the hole of the clamping plate 405 to achieve the cutting purpose.

[0025] like Figure 2 and Figure 4 As shown, an extension frame 407 is fixedly connected to the outer wall of one side of one clamp plate 405, a bolt 408 is threadedly connected in the extension frame 407, one end of the bolt 408 is rotatably connected to a contact block 409, the contact block 409 can be connected to the sliding frame 404, and the other end of the bolt 408 is fixedly connected to a rotating rod 410.

[0026] If it is necessary to cut other positions after cutting once, it is only necessary to drive the bolt 408 to rotate through the rotating rod 410, and the bolt 408 will move outward along the extension frame 407. The contact block 409 at one end of the bolt 408 will no longer contact the sliding frame 404. At this time, the position of the clamping plate 405 is no longer restricted and the position can be adjusted at will. After the movement is completed, the rotating rod 410 is rotated in the opposite direction to make the contact block 409 contact the sliding frame 404 again, so as to avoid the workpiece from being offset during processing.

[0027] like Figure 1 and Figure 2 As shown, a plurality of multi-stage telescopic rods 3 are fixedly connected between the two clamping plates 405. When one clamping plate 405 moves, the multi-stage telescopic rods 3 can drive the other clamping plate 405 to move synchronously without affecting the clamping work.

[0029] A motor 503 is fixedly mounted on the outer wall of one side of the bed body 1 , and the output end of the motor 503 is coaxially fixed with the screw rod 502 .

[0030] Start the motor 503 at one end of the bed 1, and the motor 503 drives the screw 502 to rotate. The mounting frame 2 will slowly move under the restriction of the limit groove 501 and the drive of the screw 502, and the workpiece will also be driven to be cut. The staff does not need to get close to the high-speed saw blade, making the device safer.

[0031] like Figure 4 As shown, a rubber anti-skid pad is provided on the outer wall of one end of the contact block 409 close to the sliding frame 404. When the contact block 409 contacts the sliding frame 404, the static friction between the two will be greatly increased, further enhancing the fixing effect.

[0032] The utility model provides a clamp for a sawing machine, and the specific working principle is as follows:

[0033] When the device is working, the workpiece is placed between the two clamping plates 405, and then the handle 406 on one side of the mounting frame 2 is rotated, and the handle 406 drives a bidirectional screw rod 401 to rotate. The two mounting blocks 403 will be translated close to each other under the restriction of the limit rod 402 and the drive of the bidirectional screw rod 401, and then the position of the sliding frame 404 and the clamping plates 405 therein will also change accordingly, and the workpiece will be fixed by the two clamping plates 405. If fixed in this way, when the workpiece is cut, the saw blade will directly pass through the hole of the clamping plate 405 to achieve the cutting purpose. If it is necessary to cut other positions after cutting once, it is only necessary to drive the bolt 408 to rotate by the rotating rod 410, and the screw The bolt 408 will move outward along the extension frame 407, and the contact block 409 at one end of the bolt 408 will no longer contact the sliding frame 404. At this time, the position of the clamping plate 405 is no longer restricted and the position can be adjusted at will. After the movement is completed, the rotating rod 410 is rotated in the opposite direction to make the contact block 409 contact the sliding frame 404 again, so as to avoid the workpiece from being offset during processing. Finally, the motor 503 at one end of the bed 1 is started, and the motor 503 drives the screw 502 to rotate. The mounting frame 2 will slowly move under the restriction of the limit groove 501 and the drive of the screw 502, and the workpiece will also be driven to be cut. The staff does not need to get close to the high-speed saw blade, making the device safer.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
