Diamond saw blade convenient to replace

Abstract

The utility model discloses a diamond saw blade convenient to replace. The saw blade has the beneficial effects that the quick mounting assembly is mounted on one side of the center hole of the saw blade body, so that when the saw blade body is inserted into a specified mounting position on a mounting shaft of driving equipment, the rotating sleeve can be rotated through the shifting rod, and the conical surface block is pressed into the countersunk head groove through the conical surface cavity in the rotating process of the rotating sleeve; in the same way, when the saw blade body is disassembled, only the shifting rod needs to be directly shifted to unscrew the rotating sleeve, and the pressing rod can be separated from the surface of the driving equipment mounting shaft under the action of the spring, so that the saw blade body can be quickly assembled on the driving equipment mounting shaft. Due to the fact that the saw blade body is directly disassembled and assembled in a manual screwing mode in the disassembling and assembling mode, the tedious operation of taking and using an external tool is omitted, and the replacement efficiency of the saw blade body is higher.

[0020] (III) Beneficial effects

[0021] The utility model has the following beneficial effects compared with the prior art:

[0022] In order to solve the problem that the current diamond saw blade is mainly composed of an integrated saw blade body with a center hole, the diamond saw blade of this structure is mainly installed by passing the center hole of the saw blade body through the installation shaft on the drive device, and locking and fixing it by screwing a nut on the installation shaft of the drive device. Although the diamond saw blade can be installed and disassembled in the above installation method, it is necessary to use an external screwing tool to rotate the fixing nut during the process of installing and disassembling the diamond saw blade. Since it takes a certain amount of time to use the screwing tool, it is inconvenient to install and disassemble the diamond saw blade, and it is not convenient to replace the diamond saw blade conveniently. The utility model installs a quick-install component on one side of the center hole of the saw blade body, so that When the saw blade body is inserted in the specified installation position on the driving device mounting shaft, the lever can be used to rotate the rotating sleeve, so that the conical block can be pressed into the countersunk groove through the conical cavity during the rotation of the rotating sleeve, so as to realize the pressing of the pressure rod to the surface of the driving device mounting shaft, thereby realizing the rapid installation of the saw blade body on the driving device mounting shaft. Similarly, when disassembling the saw blade body, it is only necessary to directly push the lever to loosen the rotating sleeve, so that the pressure rod can be separated from the surface of the driving device mounting shaft under the action of the spring, thereby realizing the convenient disassembly of the saw blade body. Since the saw blade body is directly disassembled and assembled by hand in the above-mentioned disassembly and assembly method, the tedious operation of taking external tools is omitted, thereby making the replacement efficiency of the saw blade body higher.

[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0029] As Figures 1-3 shown, a diamond saw blade that is convenient to replace in this embodiment includes a saw blade body 1. A central hole 3 is provided in the middle of the saw blade body 1. A quick-installation component 2 is installed on one side wall of the saw blade body 1 around the central hole 3. The quick-installation component 2 includes a mounting sleeve 201 welded to the saw blade body 1, four countersunk grooves 209 formed in a ring shape on the outer wall of the mounting sleeve 201, a pressure rod 205 installed in each countersunk groove 209, a tapered surface block 207 installed at the exposed end of the pressure rod 205, a spring 208 installed between the tapered surface block 207 and the countersunk groove 209, a threaded portion 206 formed on the outer wall of the mounting sleeve 201, a rotating sleeve 203 installed in cooperation with the threaded portion 206, a lever 204 installed in a ring shape on the outer wall of the rotating sleeve 203, and a tapered surface cavity 202 opened in the rotating sleeve 203 and cooperating with the tapered surface block 207. The spring 208 is mainly used to realize the automatic reset of the pressure rod 205 after the external force is removed, so as to ensure that the pressure rod 205 can retract into the countersunk groove 209 when the saw blade body 1 is disassembled. When the rotating sleeve 203 rotates along the surface of the mounting sleeve 201, the pressure rod 205 will move downward under the action of the tapered surface cavity 202 and the tapered surface block 207. After the pressure rod 205 moves downward, it will apply pressure to the installation shaft of the driving device, so as to realize the fixation of the saw blade body 1 on the installation shaft of the driving device.

[0030] As Figures 1-3 shown, in this embodiment, the mounting sleeve 201 is welded to the saw blade body 1, and the center of the aperture of the mounting sleeve 201 is the same as the aperture of the central hole 3, which can ensure that the saw blade body 1 can be conveniently inserted onto the installation shaft of the driving device during installation. The pressure rod 205 penetrates through the countersunk groove 209 and is slidably connected to the countersunk groove 209. The countersunk groove 209 penetrates through the side wall of the mounting sleeve 201. The pressure rod 205 is the main component for connecting the saw blade body 1 and the installation shaft of the driving device. The pressure rod 205 penetrates through the spring 208. One end of the spring 208 is welded to the countersunk groove 209, and the other end of the spring 208 is welded to the tapered surface block 207.

[0031] As Figures 1-3 shown, in this embodiment, the side of the tapered surface block 207 facing away from the pressure rod 205 is a tapered surface structure, and the taper of the tapered surface block 207 matches the taper of the tapered surface cavity 202. The rotating sleeve 203 is screwed to the threaded portion 206, and the rotating sleeve 203 is welded to the lever 204. With the help of the lever 204, the convenient rotation adjustment of the rotating sleeve 203 can be realized without using external screwing tools. The outer side of the saw blade body 1 is also provided with heat dissipation grooves, which can ensure the efficient heat dissipation of the saw blade body 1 during rotation cutting.

[0032] The specific implementation process of this embodiment is as follows: when in use, first insert the saw blade body 1 into the corresponding position on the drive device mounting shaft, and then only need to use the lever 204 to rotate the rotating sleeve 203, so that during the rotation of the rotating sleeve 203, the pressure rod 205 can be moved downward under the action of the conical cavity 202 and the conical block 207. After the pressure rod 205 moves downward, it will exert pressure on the drive device mounting shaft, thereby achieving the fixation of the saw blade body 1 on the drive device mounting shaft. When the saw blade body 1 needs to be disassembled, only need to directly push the lever 204 to loosen the rotating sleeve 203, so that the pressure rod 205 can be separated from the surface of the drive device mounting shaft under the action of the spring 208, thereby realizing the convenient disassembly of the saw blade body 1. Since the saw blade body 1 is directly disassembled and assembled by hand in the above-mentioned disassembly and assembly method, the tedious operation of taking external tools is omitted, thereby making the replacement efficiency of the saw blade body 1 higher.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
