The upper surface of the milling cutter disc body is connected to a connecting disc, a cutter rod is inserted into the mounting hole, and the disassembly assembly includes a sliding member and a fixed rod, the sliding member is slidably arranged in the connecting disc, and one end of the sliding member is connected to the fixed rod, a socket corresponding to the fixed rod is provided on the surface of the cutter rod, a spring is provided in the connecting disc, and one end of the spring is connected to the sliding member. The utility model uses the cooperation of the pull block and the sliding member to pull the fixed rod out of the socket of the cutter rod, which is convenient for removing the cutter rod from the connecting disc, inserting the replaced cutter rod into the mounting hole, and using the cooperation of the spring and the sliding member to insert the fixed rod into the socket, which is beneficial to the stability of the cutter rod on the connecting disc and convenient for installing the cutter rod on the connecting disc.

[0004] With the above arrangement, the milling cutter disc described in the prior art is provided with a cutter bar and a fixing rod, so that when installing the cutter bar, the fixing rod is pulled out. When the cutter bar is inserted into the cavity, the fixing rod is inserted into the cutter bar by a spring, thereby limiting the cutter bar and facilitating installation of the cutter bar on the connecting disc. However, the milling cutter disc of the prior art solution has the following defects during operation:

[0005] When installing the milling cutter disc body described in the prior art, the milling cutter blade needs to be fixed on the milling cutter disc body by bolts. Since there are many milling cutter blades that need to be fixed, each needs to be fixed by bolts, which makes the operation very troublesome and requires tools to disassemble and assemble them, which is inconvenient for the installation and disassembly of the milling cutter blade. Utility Model Content

[0006] The utility model aims to provide a milling cutter disc which is convenient for disassembling and assembling a milling cutter, and is mainly used to solve the technical problem in the prior art that it is inconvenient to install and disassemble the milling cutter blade.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] A milling cutter disc that is easy to disassemble and assemble a milling cutter, comprises a milling cutter disc body and a milling cutter blade. A plurality of slots are provided on one side of the milling cutter disc body, and an insert block matching the slots is fixedly connected to one side of the milling cutter blade. A limiting hole is provided on one side of the insert block, and the insert block is plugged into the slot. A through slot is provided on the inner wall of one side of the slot, and a fixed slot is provided on the inner wall of the other side of the slot. A through hole is provided on the bottom surface of the through slot, and the through hole passes through the milling cutter disc body. The through slot corresponds to the fixed slot and the through hole, and a pull rod is slidably connected to the inner wall of the through slot. One end of the pull rod is fixedly connected to the limiting rod inside the through slot, and a first spring is provided on the outer wall of the pull rod, one end of the first spring is fixedly connected to the bottom surface of the through slot, and the other end of the first spring is fixedly connected to one end of the limiting rod. The limiting rod is slidably connected to the through slot, and the limiting rod is plugged into the limiting hole and the fixing slot, and a rebound structure is installed on the bottom surface of the slot.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When the milling cutter blade needs to be installed, first align the insert block and guide block on the milling cutter blade with the slot and guide groove respectively, and then insert it. After the insert block enters the slot, it will first resist the slide. At this time, you need to continue to push the milling cutter blade so that the slide compresses the second spring. At this time, the limit rod will slide on the upper surface of the slide and the insert block. When the limit rod slides to the top of the limit hole, the limit rod is pushed into the inside of the limit hole under the action of the first spring force, and resists the fixed groove to complete the installation. When disassembly is required, pull the pull rod upward so that the pull rod drives the limit rod to compress the first spring and disengage the limit rod from the limit hole. At this time, the slide will push the milling cutter blade and the insert block outward a short distance under the action of the second spring force, and then release the pull rod. The limit rod resists the slide to complete the disassembly.

[0011] 2.Beneficial effects:

[0012] The prior art provides a cutter bar and a fixing rod, so that when installing the cutter bar, the fixing rod is pulled out, and when the cutter bar is inserted into the cavity, the fixing rod is inserted into the cutter bar by a spring, so as to limit the cutter bar and facilitate the installation of the cutter bar on the connecting disk. However, when installing the existing milling cutter disc body, the milling cutter blade needs to be fixed to the milling cutter disc body by bolts. Since there are many milling cutter blades that need to be fixed, each of which needs to be fixed by bolts, the operation is very troublesome, and tools are also needed to be used to disassemble it. The present invention provides an insert block and a limit rod, so that when installing, the insert block is inserted into the interior of the slot, and then the limit rod is inserted into the interior of the limit hole by the elastic force of the first spring to limit the insert block. When disassembly is required, the pull rod is pulled, so that the slide plate moves the insert block and the milling cutter blade outward a short distance under the action of the elastic force of the second spring, so that the limit rod and the slider are against each other, and the insert block and the milling cutter blade can be disassembled. The disassembly and assembly are very convenient, which effectively solves the technical problem of the inconvenient disassembly and assembly of the milling cutter blade.

[0013] Preferably, the rebound structure includes a second spring, one end of which is fixedly connected to the bottom surface of the slot, and the other end of the second spring is fixedly connected to a slide, which is slidably connected to the inner wall of the slot and abuts against the insert. By providing the rebound structure, when removing the milling cutter blade, the elastic force of the second spring pushes the slide to move the milling cutter blade and the insert a short distance, so that the slide blocks the limit rod, facilitating its removal. The slide can also block the limit rod, facilitating replacement of the milling cutter blade.

[0014] Preferably, the outer wall of the pull rod is provided with a curved plate, the upper surface of which is provided with a movable groove corresponding to the pull rod. A knob is fixedly connected to one end of the pull rod located on the curved plate, and the knob is movable within the movable groove, allowing the pull rod and the curved plate to slide relative to each other. By providing the curved plate and the knob, the milling cutter blade can be disassembled in multiple or individual ways. Pulling the curved pull block to lift the curved plate allows for multiple disassembly, while pulling the knob allows for individual disassembly, making disassembly more diverse and very convenient.

[0015] Preferably, the milling cutter disc body is symmetrically provided with guide grooves on one side of the slot, and the milling cutter blade is symmetrically provided with guide strips corresponding to the guide grooves on one side of the insert block, and the guide strips are plugged into the guide grooves. The guide grooves and guide strips can fix the direction of the milling cutter blade and make the milling cutter blade more firmly fixed to prevent it from falling.

[0016] Preferably, the inner wall of the curved plate is fixed with a curved pull block, the inner wall of the curved pull block is provided with a pull groove, and the inner wall of the pull groove is fixed with an anti-slip pad. By arranging the curved pull block, the curved plate can be pulled up, making it convenient to disassemble multiple milling cutter blades.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-5As shown, a milling cutter disc that is easy to disassemble and assemble a milling cutter includes a milling cutter disc body 1 and a milling cutter blade 2, characterized in that a plurality of slots 3 are opened on one side of the milling cutter disc body 1, and a guide groove 16 is symmetrically opened on one side of the milling cutter disc body 1 located at the slot 3, and a guide strip 17 corresponding to the guide slot 16 is symmetrically opened on one side of the insert block 4, and the guide strip 17 is plugged into the guide slot 16, and an insert block 4 matching the slot 3 is fixedly connected to one side of the insert block 4, and a limiting hole 7 is opened on one side of the insert block 4, and the insert block 4 is plugged into the slot 3, a through groove 20 is opened on the inner wall of one side of the slot 3, and a fixed groove 5 is opened on the inner wall of the other side of the slot 3, and a through hole 6 is opened on the bottom surface of the through groove 20, and the through hole 6 passes through the milling cutter disc body 1, and the through groove 20 corresponds to the fixed groove 5 and the through hole 6, and the inner wall of the through hole 6 is slidably connected with a pull rod 8, and the pull rod 8 is fixedly connected to the limiting rod 9 at one end inside the through groove 20 The outer wall of the pull rod 8 is provided with a first spring 10, one end of the first spring 10 is fixed to the bottom surface of the through slot 20, and the other end of the first spring 10 is fixed to one end of the limit rod 9, the limit rod 9 is slidably connected with the through slot 20, and the limit rod 9 is plugged into the limit hole 7 and the fixing slot 5, and a rebound structure is installed on the bottom surface of the slot 3. The rebound structure includes a second spring 11, one end of the second spring 11 is fixed to the bottom surface of the slot 3, and the other end of the second spring 11 is fixedly connected to a slide plate 12. The slide plate 12 is located at the inner wall of the slot 3 and is slidably connected, and the slide plate 12 is against the insert block 4. By setting the rebound structure, when the milling cutter blade 2 is disassembled, the elastic force of the second spring 11 pushes the slide plate 12 to move the milling cutter blade 2 and the insert block 4 a short distance, so that the slide plate 12 blocks the limit rod 9, which is convenient for taking it out, and can also block the limit rod 9, which is convenient for replacing the milling cutter blade 2.

[0027] As shown in the figure, the outer wall of the pull rod 8 is sleeved with an arc-shaped plate 13, and the upper surface of the arc-shaped plate 13 is provided with a movable groove 14 corresponding to the pull rod 8. The pull rod 8 is located at one end of the arc-shaped plate 13 and is fixed with a knob 15, and the knob 15 is located inside the movable groove 14 and moves. The pull rod 8 and the arc-shaped plate 13 slide relative to each other, and the inner wall of the arc-shaped plate 13 is fixed with an arc-shaped pull block 18, and the inner wall of the arc-shaped pull block 18 is provided with a pull groove 19, and the inner wall of the pull groove 19 is fixed with an anti-slip pad. By setting the arc-shaped pull block 18, the arc-shaped plate 13 can be pulled up, which is convenient for disassembly of multiple milling cutter blades 2. By setting the arc-shaped plate 13 and the knob 15, the milling cutter blade 2 can be disassembled multiple times and individually. Pull the arc-shaped pull block 18 to pull up the arc-shaped plate 13 for multiple disassembly, and pull the knob 15 for individual disassembly. The disassembly is more diverse and very convenient.

[0028] From the above, it can be seen that the specific implementation of the present utility model is as follows:

[0029] When the milling cutter blade 2 needs to be installed, first align the plug block 4 and the guide bar 17 on the milling cutter blade 2 with the slot 3 and the guide groove 16, and then insert it. First, the plug block 4 will be against the slide plate 12. At this time, it is necessary to continue to push the milling cutter blade 2 so that the slide plate 12 squeezes the second spring 11. At this time, the limit rod 9 will slide on the upper surface of the slide plate 12 and the plug block 4. When the limit rod 9 slides to the top of the limit hole 7, the limit rod 9 will be inserted into the inside of the limit hole 7 under the action of the elastic force of the first spring 10, and will be against the fixing groove 5 to complete the installation. When the milling cutter blade 2 needs to be disassembled, it is first necessary to determine whether to perform multiple disassemblies or single disassembly. When multiple disassemblies are required, the pull groove 19 on the arc pull block 18 needs to be pulled so that the arc plate 1 3 moves up. When a single disassembly is required, the knob 15 needs to be pulled. Both methods will drive the pull rod 8 to move upward, so that the pull rod 8 drives the limit rod 9 to move upward and starts to squeeze the first spring 10. At this time, the limit rod 9 will break away from the fixing groove 5 and the limit hole 7 and enter the inside of the through groove 20. At this time, the slide plate 12 will push the milling cutter blade 2 and the insert block 4 outward for a short distance under the action of the elastic force of the second spring 11. At this time, the slide plate 12 will block the through groove 20, and then release the knob 15 or the arc-shaped pull block 18. The limit rod 9 will be against the slide plate 12 under the action of the first spring 10, and then the milling cutter blade 2 can be taken out to complete the disassembly. The state of the slide plate 12 and the limit rod 9 when the disassembly is completed is the state of the slide plate 12 and the limit rod 9 before the milling cutter blade 2 is installed.

[0030] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
