DETAILED DESCRIPTION

[0025] In order to better understand the purpose, structure and function of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings.

[0026] like Figure 1-Figure 3 As shown, the raw material positioning fixture of the cutting machine of the utility model includes a base 1, a support arm 6, a cutting assembly and a positioning assembly. The support arm 6 is fixedly installed on the right side of the top surface of the base 1, the cutting assembly is slidably installed on the left side of the support arm 6, and the positioning assembly is rotatably installed on the top of the base 1.

[0027] The cutting assembly includes a sliding arm 7 , a rotating shaft 9 is fixedly mounted on the left side of the sliding arm 7 , a cutting saw blade 10 is rotatably mounted on the outer surface of the rotating shaft 9 , and a protective shell 8 is fixedly mounted on the outer surface of the rotating shaft 9 .

[0028] In this embodiment, a transmission pulley located in the inner cavity of the support arm 6 is fixedly installed on the right side of the sliding arm 7. The upper and lower transmission pulleys are used to slide the cutting assembly up and down to achieve cutting at different depths. The outer surface of the cutting saw blade 10 is connected to a wire located on the inner side of the protective shell 8. The wire is set in the inner cavity of the sliding arm 7. Due to the different electrical properties of the human body and wood, a weak current is applied to the cutting saw blade 10. When the hand touches the cutting saw blade, the relatively large capacitor inside the human body will change the electrical signal, triggering the gunpowder explosion to bounce off the cutting saw blade 10 in a very short moment.

[0029] The positioning assembly comprises a turntable 2 , a clamping plate 3 is fixedly mounted on the top surface of the turntable 2 , and two positioning plates 4 and four clamping plates 5 are slidably mounted on the top surface of the clamping plate 3 .

[0030] In this embodiment, the inner cavity of the splint 3 is provided with four equidistant first cutting grooves 31 for accommodating the cutting saw blade 10 for deep cutting. The outer surfaces of the four first cutting grooves 31 are slidably installed with a locking plate 5 for fixing the raw materials on all sides. A working plate 34 is fixedly installed on the surface of the splint 3. The working plate is coated with an anti-corrosion coating to facilitate cutting of raw materials of different materials without damaging the splint 3. Slide rails 32 are provided on the left and right sides of the top of the working plate 34. Two electric pulleys 41 are provided on the bottom surfaces of the two positioning plates 4. The two electric pulleys 41 are slidably installed on the outer surface of the slide rails 32 for sliding the two positioning plates 4 relative to each other to play a role of positioning and clamping. An adhesive sheet 33 is fixedly installed at the connecting part of the two slide rails 32.

[0031] In this embodiment, the opposing surfaces of the two positioning plates 4 are provided with anti-slip interlayers, the adhesive sheet 33 is sticky and is used to slightly fix the raw materials and facilitate removal. The positioning plate 5 is chamfered and is divided into four equal parts at the top corners of the splint 3 for easy fixation.

[0032] The left side of the support arm 6 is slidably connected to the sliding arm 7. The turntable 2 is rotatably installed on the top of the base 1. Cutting at different angles is achieved by rotation. The inner cavity of the turntable 2 is provided with a second cutting groove 21 for accommodating an overly deep cutting saw blade 10. A buffer pad 22 is provided on the bottom surface of the turntable 2 to protect the base 1. A rotating groove 11 corresponding to the turntable 2 is provided on the top of the base 1 to facilitate rotation and prevent damage.

[0033] In this embodiment, the working principle in the above embodiment is:

[0034] The raw material is placed on the upper surface of the adhesive sheet 33, and the two positioning plates 4 are clamped by electrically controlled relative sliding, and the four clamping plates 5 are relatively slid to fit tightly against the raw material to fix it. The sliding arm 7 is then slid downward on the support arm 6 to perform cutting. When the cutting angle needs to be adjusted, the sliding arm 7 is slightly lifted to move the cutting saw blade 10 away from the raw material. The turntable 2 is electrically controlled to rotate the clamping plate 3, and then the cutting saw blade 10 is lowered for cutting.

[0035] The beneficial effects of the above embodiment are:

[0036] By electrically controlling the relative sliding of the two positioning plates 4 and then electrically sliding the four positioning plates 5, the positioning fixture is used to stably fix the raw material on the surface of the adhesive sheet 33, and the angle of the raw material can be adjusted by rotating the turntable 2 to perform cutting operations at different angles.

[0037] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make several modifications and improvements without departing from the principle of the present invention, and these modifications and improvements should also be considered to belong to the protection scope of the present invention.
