Saw blades can be divided into bimetallic saw blades, carbide sand saw blades, high-speed steel saw blades, carbon steel saw blades, etc., which can be used to cut pipes, solid objects, wood, plastics and other materials.

[0003] At present, in the saw blade production process, it is necessary to drill holes in the saw blade separately for installing the saw blade handle, so drilling equipment is needed. The existing drilling equipment uses a motor to drive the drill bit to rotate for drilling operations, and the saw blade is placed on a stable support platform, and the saw blade is fixed on the workbench by a clamping device. The operator aligns the drill bit with the target position and drills the saw blade through the rotating drill bit.

[0004] In actual use of the prior art, the operator needs to align the saw blade with the drill bit by visual observation. Since it is often difficult to achieve completely accurate alignment through manual operation, even experienced operators may have slight errors, which may lead to deviations in the drilling position and affect the accuracy and quality of the drilling. Therefore, a saw blade production drilling device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] Example 1

[0026] Reference Figure 1 and Figure 2 , which is the first embodiment of the utility model, and provides a saw blade production drilling device, including a base 1 and a pillar 101, the pillar 101 is fixedly connected to the upper surface of the base 1, a top plate 102 is fixedly connected to the upper surface of the pillar 101, a placement plate 103 is connected to the upper surface of the base 1, a pressing mechanism 2 is arranged on the lower surface of the top plate 102, and a drilling mechanism 3 is arranged on the lower surface of the pressing mechanism 2;

[0027] The pressing mechanism 2 includes an electric push rod 201 fixedly connected to the lower surface of the top plate 102, a circular plate 202 fixedly connected to the lower surface of the electric push rod 201, a connecting rod 203 fixedly connected to the outer surface of the circular plate 202, a sliding rod 204 inserted into the inner cavity of the connecting rod 203, and a lower pressing plate 205 fixedly connected to the lower end of the sliding rod 204;

[0028] Specifically, a spring 206 is sleeved on the outer surface of the sliding rod 204 , and two ends of the spring 206 are fixedly connected to the connecting rod 203 and the lower pressing plate 205 respectively. Holes 207 are opened in the inner cavities of the placement plate 103 and the lower pressing plate 205 .

[0029] Further, the electric push rod 201 is started to drive the circular plate 202 to move downward. At this time, when the two connecting rods 203 move downward, the sliding rod 204 and the spring 206 cooperate to drive the lower pressure plate 205 to move downward to squeeze the saw blade and fix it on the placement plate 103. When the connecting rod 203 moves downward, it will continue to squeeze the spring 206 to generate a downward squeezing force to drive the lower pressure plate 205 to squeeze the saw blade firmly on the placement plate 103 to avoid displacement of the saw blade during drilling.

[0030] Example 2

[0031] Reference Figure 2 , Figure 3 and Figure 4 , which is the second embodiment of the utility model, this embodiment is based on the previous embodiment, and a drilling mechanism 3 is provided on the lower surface of the pressing mechanism 2;

[0032] The drilling mechanism 3 includes a drilling motor 301 fixedly connected to the lower surface of the circular plate 202, a mounting sleeve 302 fixedly connected to the output shaft end of the drilling motor 301, a hollow drill bit 303 movably connected to the inner cavity of the mounting sleeve 302, a protective sleeve 307 movably connected to the lower surface of the mounting sleeve 302, and a small laser pen 308 fixedly connected to the middle of the lower surface of the protective sleeve 307;

[0033] Specifically, the mounting sleeve 302 is fixedly connected to the hollow drill bit 303 through a screw rod 304 and a nut 305 , and a connecting pipe 306 is fixedly connected to the lower surface of the mounting sleeve 302 , and threads are provided on the outer surface of the connecting pipe 306 and the inner cavity of the protective sleeve 307 , and the connecting pipe 306 is threadedly connected to the protective sleeve 307 .

[0034] Further, the base 1 is placed at a designated location, and then the saw blade of the instrument to be punched is placed on the placement plate 103, and the position to be punched is aligned with the hole 207. At this time, the small laser pen 308 is started to emit laser to hit the saw blade to form a light spot. The position of the laser spot on the saw blade is used to determine whether the drilling position required by the saw blade is aligned with the hollow drill bit 303. At the same time, the position of the laser spot can be used to assist the operator to quickly and accurately find the placement position of the saw blade drilling point, thereby avoiding the operator's difficulty in aligning the saw blade with the drill bit through naked eye observation, resulting in slight errors, which makes it easy for the drilling position to deviate, thereby improving the accuracy of the drill bit and saving manual observation and adjustment. And the time cost spent on confirming the alignment, when the saw blade is positioned correctly, the protective sleeve 307 is rotated and removed from the connecting tube 306, and when the circular plate 202 moves downward, the drilling motor 301 is started to drive the hollow drill bit 303 to rotate and drill the saw blade. Due to the design of the hollow drill bit 303, the cutting area is subjected to less contact pressure, thereby reducing the cutting force and extrusion force on the workpiece, thereby producing a smoother and higher-quality hole surface. After the drilling is completed, the drilling motor 301 is turned off and the electric push rod 201 is started to drive the lower pressure plate 205 to move upward, so that the operator can take out the saw blade after the drilling is completed. The hollow drill bit 303 can be removed by rotating the screw 304 and the nut 305, thereby improving the practicability of the device.

[0035] Working principle: During the use of the device, the base 1 is placed at the designated location, and then the saw blade of the instrument to be punched is placed on the placement plate 103, and the position to be punched is aligned with the hole 207. At this time, the small laser pen 308 is started to emit a laser to hit the saw blade to form a light spot. The position of the laser spot on the saw blade is used to determine whether the drilling position required by the saw blade is aligned with the hollow drill bit 303. At the same time, the position of the laser spot can be used to assist the operator to quickly and accurately find the placement position of the saw blade drilling point, so as to avoid the operator's difficulty in achieving completely accurate alignment when aligning the saw blade with the drill bit through naked eye observation, resulting in slight errors and easy deviations in the drilling position, thereby improving the accuracy of the drill bit and saving the time cost of manual observation, adjustment and confirmation of alignment. When the saw blade position is located, the protective cover 307 is removed from the connecting tube 306 by rotating it, and the electric push rod 201 is started to drive the circular plate 202 to move downward. When the two connecting rods 203 move downward, the sliding rod 204 and the spring 206 cooperate to drive the lower pressure plate 205 to move downward to squeeze the saw blade and fix it on the placement plate 103. When the connecting rod 203 moves downward, it will continue to squeeze the spring 206 to generate a downward squeezing force to drive the lower pressure plate 205 to squeeze the saw blade firmly on the placement plate 103 to avoid displacement of the saw blade during drilling. When the circular plate 202 moves downward, the drilling motor 301 is started to drive the hollow drill bit 303 to rotate and drill the saw blade. Due to the design of the hollow drill bit 303, the cutting area is subjected to less contact pressure, thereby reducing the cutting force and squeezing force on the workpiece, thereby producing a smoother and higher-quality hole surface. After the drilling is completed, the drilling motor 301 is turned off and the electric push rod 201 is started to drive the lower pressure plate 205 to move upward, so that the operator can take out the saw blade after the drilling is completed. The hollow drill bit 303 can be removed by rotating the screw 304 and the nut 305, thereby improving the practicality of the device.
