Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool processing and relates to an automatic clamping device, in particular to an automatic clamping device for feeding workpieces of sawing machine tools. Background Art

[0002] Mechanical equipment is widely used. With the rapid development of society, a wide range of tools and equipment are needed in infrastructure construction, industrial production, and the production of daily necessities. In particular, various machine tools are used for processing. When a portion of a workpiece needs to be cut off, the traditional solution is to use a saw blade with a fixed spindle. The blade only rotates, cutting one side before turning over to cut the other. When using a sawing machine, a worker must first secure the workpiece on the operating table. Once the workpiece is securely fixed, the machine can then be started to process the workpiece.

[0003] A search revealed a workpiece fixing device and a casting riser sawing machine using the same, as disclosed in Chinese patent documents [Application Number: 202220037091.6; Publication Number: CN 217316181 U]. The device comprises a support base, a fixed base, and a fixed cylinder. The fixed cylinders are symmetrically arranged on the fixed base, and the fixed base is also provided with a workpiece limiting column. The ends of the fixed cylinder piston rods are each provided with a workpiece fixing block. The fixed base is slidably connected to the support base. The support base is provided with a fixed base drive mechanism, including a frame, a sawing machine, a feed mechanism, and a displacement mechanism. The support base is provided on the frame, a bracket is provided on one side of the support base, the displacement mechanism is provided on the bracket, the feed mechanism is provided at the output end of the displacement mechanism, and the sawing machine is provided above the support base at the output end of the feed mechanism. The fixed cylinder is provided in conjunction with the workpiece limiting column to fix the workpiece on the fixed base, facilitating subsequent sawing of the workpiece and preventing movement of the workpiece during sawing.

[0004] Although this patent sets a fixed cylinder to cooperate with the workpiece limiting column to fix the workpiece on the fixed base, which facilitates the subsequent sawing of the workpiece and avoids the movement of the workpiece during the sawing process, this patent cannot set the feed line and auxiliary line on the workpiece when fixing the workpiece, resulting in an increase in the workload of the personnel when sawing the workpiece, affecting the sawing effect and accuracy.

[0031] The material can be passed through the clamping mouth 2, and the clamping component can be used to fix the material, which is convenient for subsequent sawing of the material and improves the overall work efficiency. The driving component can then control the driving wheel 3 to rotate, and the driving wheel 3 can further drive the regulating wheel 4 to rotate through the cutting belt 5. In this way, the continuously operating cutting belt 5 can rub the surface of the material and grind out traces of auxiliary sawing marks, which is convenient for subsequent sawing work.

[0032] The limiting assembly includes a mounting frame 6 fixed on the frame body 1 , a limiting screw 7 rotatably connected to the mounting frame 6 , and one end of the limiting screw 7 presses against the rotating shaft of the regulating wheel 4 .

[0033] With the above structure, the limit screw 7 can be rotated to adjust the pressure between one end of the limit screw 7 and the rotating shaft of the regulating wheel 4, thereby achieving control of the speed of the regulating wheel 4 and improving the uniformity of the force during friction cutting.

[0034] The drive assembly includes a drive frame 8 fixed on the frame 1, a worm gear 9 rotatably connected inside the drive frame 8, a worm 10 rotatably connected inside the drive frame 8, the worm 10 is engaged with the worm gear 9, and a drive motor 11 is fixed inside the frame 1, the output shaft of the drive motor 11 is coaxially fixedly connected to the worm 10 through a coupling 18, and the worm gear 9 is coaxially fixedly connected to the drive wheel 3.

[0035] With the above structure, the worm 10 can be driven to rotate by the driving motor 11, and the worm 10 can further drive the worm wheel 9 to rotate by meshing with the worm wheel 9. When the worm wheel 9 rotates, it will drive the entire driving wheel 3 to rotate, thereby realizing the function of automatic cutting.

[0036] A pair of adjustment frames 12 are rotatably connected to the frame body 1, and a pair of servo motors are fixed inside the frame body 1.

Personnel can identify the sawing length and angle through the marks, so as to improve the sawing accuracy. When the cutting is completed, the material can be loosened and then conveyed to the subsequent sawing equipment through the conveying roller 15. At this time, the material is clamped to assist in completing the sawing work.

[0043] In summary, by passing the material through the clamping mouth 2, the material is fixed by the clamping component, which facilitates the subsequent sawing of the material and improves the overall work efficiency. The driving component controls the driving wheel 3 to rotate, and the driving wheel 3 further drives the regulating wheel 4 to rotate through the cutting belt 5.
