Description

Technical Field

[0001] The utility model relates to the technical field of cutters, in particular to a cutter with an auxiliary positioning function. Background Art

[0002] A cutter is an essential tool for cutting various papers, photos, art cardboard, hot and cold mounted paper. It is usually made of steel, stainless steel and carbon steel. The blade is specially treated, making it sharp and durable. The cut products are neat and hairless.

[0003] However, the following problems may occur when the cutter is cutting: 1. There is no auxiliary positioning function during cutting, and the cutting quality of the workpiece cannot be guaranteed; 2. The workpiece needs to be taken out manually after cutting, which may cause the risk of hitting the cutter, and manual removal will also affect production efficiency. In view of the above problems, a cutter with auxiliary positioning function is proposed. Utility Model Content

[0004] The main purpose of the utility model is to provide a cutting knife with auxiliary positioning function, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A cutter with auxiliary positioning function includes a table top, characterized in that: a rectangular groove is opened in the middle of the upper end of the table top, a clamping device is installed on the left part of the upper end of the rectangular groove, support frames are fixedly installed at the front and rear of the upper end of the table top, a hydraulic cylinder fixing plate is fixedly installed on the upper end of the support frame, a hydraulic cylinder is fixedly installed in the middle of the upper end of the hydraulic cylinder fixing plate, a cutting device is fixedly installed at the output end of the hydraulic cylinder, and a pushing device is installed in the middle of the lower end of the table top.

[0007] Preferably, the cutting device comprises a cutting knife mounting frame, a cutting knife is fixedly mounted in the middle of the lower end of the cutting knife mounting frame, a spring column mounting plate is fixedly mounted at the lower left end of the cutting knife mounting frame, a spring column is fixedly mounted at the lower end of the spring column mounting plate, a pressure plate is fixedly mounted at the lower end of the spring column, and the upper end of the cutting knife mounting frame is fixedly connected to the output end of the hydraulic cylinder. By fixing the spring column on the upper end of the pressure plate, the spring in the spring column is compressed during cutting, generating a downward elastic force on the pressure plate, thereby being able to press the workpiece tightly and ensure the stability of the workpiece during cutting.

[0008] Preferably, the clamping device comprises a mounting frame, and the left inner wall and the right inner wall of the mounting frame are fixedly mounted with electric telescopic rods, and the output end of the electric telescopic rod is fixedly mounted with a clamping plate. When the mounting frame pushes the workpiece to a suitable cutting position, the electric telescopic rod pushes the clamping plate to move, clamps the workpiece, and ensures the stability of the workpiece during cutting.

[0009] Preferably, the pushing device comprises a left mounting plate and a right mounting plate, a servo motor is fixedly mounted on the right end of the right mounting plate, a screw is fixedly connected to the output end of the servo motor, the screw passes through the left mounting plate and the right mounting plate, the left mounting plate and the right mounting plate are rotatably connected to the screw, the screw is threadedly connected to a connecting block, the connecting block is movably inserted in the rectangular groove, the upper end of the connecting block is fixedly connected to the mounting frame, and the left mounting plate and the right mounting plate are fixedly mounted on the lower left and lower right parts of the table board respectively. By starting the servo motor to drive the screw to rotate, the screw is threadedly matched with the connecting block, and the connecting block drives the clamping device to move along the rectangular groove, thereby pushing the workpiece to a suitable cutting position.

[0010] Preferably, the shape and size of the connecting block are adapted to the rectangular groove, and the connecting block and the rectangular groove are slidably matched.

[0011] Preferably, the vertical distance between the upper end of the pressing plate and the table top is smaller than the vertical distance between the lower end of the cutting knife and the table top.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The cutting device is driven by a hydraulic cylinder. When cutting the workpiece, the height of the pressing plate is lower than that of the cutter. As the cutting device is pressed down, the pressing plate contacts the workpiece surface earlier than the cutter. Under the action of the spring column, the pressing plate has already pressed the workpiece before the cutter cuts the workpiece. Therefore, when the cutter cuts, the pressing plate is pressed to better ensure the cutting quality of the workpiece.

[0014] 2. By setting a servo motor, a screw and a connecting block in the pushing device, turning on the servo motor to drive the screw to rotate, so that the screw and the connecting block thread cooperate, so that the connecting block drives the clamping device to move along the rectangular groove, thereby pushing the workpiece to a suitable cutting position. Before cutting, the clamping plate is pushed by the electric telescopic rod in the clamping device to clamp and position the workpiece to ensure the stability of the workpiece during cutting.

[0015] 3. After the cutting is completed, the servo motor in the pushing device is started to allow the clamping device to push out the cut workpiece, making it easier for workers to take out the cut workpiece, which not only improves work efficiency but also does not put workers at risk of touching the knife.

[0025] The cutting device 4 includes a cutter mounting frame 40, a cutter 44 is fixedly mounted at the middle of the lower end of the cutter mounting frame 40, a spring column mounting plate 41 is fixedly mounted at the lower left end of the cutter mounting frame 40, a spring column 42 is fixedly mounted at the lower end of the spring column mounting plate 41, a pressing plate 43 is fixedly mounted at the lower end of the spring column 42, and the upper end of the cutter mounting frame 40 is fixedly connected to the output end of the hydraulic cylinder 8. By fixing the spring column 42 at the upper end of the pressing plate 43, the spring in the spring column 42 is compressed as the cutter 44 descends, generating a downward elastic force on the pressing plate 43, thereby being able to press the workpiece tightly to ensure the stability of the workpiece during cutting.

[0026] The clamping device 2 includes a mounting frame 20, and an electric telescopic rod 21 is fixedly mounted on the left inner wall and the right inner wall of the mounting frame 20, and a clamping plate 22 is fixedly mounted on the output end of the electric telescopic rod 21.

First, the servo motor 54 is turned on to drive the screw rod 52 to rotate, so that the screw rod 52 is threadedly matched with the connecting block 51, so that the connecting block 51 drives the clamping device 2 to move along the rectangular groove 3, thereby pushing the workpiece to a suitable cutting position. Before cutting, the clamping plate 22 is pushed by the electric telescopic rod 21 in the clamping device 2 to clamp and position the workpiece. When cutting the workpiece, since the height of the pressing plate 43 is lower than the height of the cutting knife 44, the pressing plate 43 contacts the surface of the workpiece earlier than the cutting knife 44 during cutting. Under the action of the spring column 42, the pressing plate 43 will press the workpiece to ensure the stability of the workpiece during cutting. After the cutting is completed, the servo motor 54 in the pushing device 5 is started to allow the clamping device 2 to push out the cut workpiece, which is convenient for workers to take out the cut workpiece, which not only improves work efficiency but also does not put workers at risk of touching the knife.
