Description

Technical Field

[0001] This utility model relates to the technical field of saw changing equipment for sawing machines, and in particular to a saw changing mechanism for sawing machines. Background Technology

[0002] A band saw is a machine tool that uses a saw blade, band saw, or saw strip as a cutting tool to cut materials such as metal and wood. The main types include band saws, circular saws, and bow saws, and they are widely used in industrial processing.

[0003] Currently, sawing machines are mainly used for cutting metal materials. During long-term use, the saw blades on these machines experience wear and aging, resulting in dull blades and affecting the cutting of metal materials. Therefore, the saw blades need to be replaced after a period of use. During the installation process, the operator needs to hold the saw blade and apply counter-clockwise force, then use a wrench to turn the bolts clockwise to fix the outer flange to the sawing machine, thus securing the saw blade. This operation, requiring the operator to hold the saw blade, is prone to hand injuries. Therefore, we propose a saw blade changing mechanism for sawing machines. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a saw-changing mechanism for a sawing machine. By connecting the saw blade to a support plate, the saw blade and the support plate rotate synchronously, thereby limiting the position of the support plate and preventing the operator from directly contacting the saw blade.

[0005] To solve the above-mentioned technical problems, this utility model provides a solution to address the issue of operators being easily injured when directly contacting the saw blade.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A saw changing mechanism for a sawing machine includes a support plate, a movable column mounted on the axis of the support plate, a hexagonal block fixedly connected to the end of the movable column, multiple sets of connecting pipes mounted on the support plate, suction cups provided at the ends of the connecting pipes, a connecting plate fixedly connected to the support plate, a handle fixedly connected to the connecting plate, and an air venting device installed at the end of the connecting pipe for releasing the internal air pressure of the connecting pipe, thereby disengaging the suction cups from the saw disc.

[0008] Preferably, the venting component includes a sleeve fitted onto the outer side of the movable column. An operating block fitted onto the outer side of the movable column is fixedly connected to one end of the sleeve, and a connecting ring fitted onto the outer side of the movable column is fixedly connected to the other end of the sleeve. Multiple sets of connecting plates are fixedly connected to the connecting ring, and connecting columns are fixedly connected to the connecting plates. A sealing plug is fixedly connected to the end of each connecting column. Multiple sets of sealing plugs are respectively installed at the end positions of the connecting tube. An elastic element connected to the connecting tube is installed on the sealing plug to facilitate the release of air pressure inside the connecting tube, thereby allowing the suction cup to communicate with the air and preventing negative pressure from being generated inside the suction cup, thus facilitating the separation of the suction cup from the saw disc.

[0009] Preferably, the elastic element includes a fixing plate fixed inside the connecting tube, the fixing plate having several sets of through holes, and a sliding post slidably connected to the fixing plate, the sliding post being fixedly connected to the sealing plug, and a tension spring being fixedly connected between the sealing plug and the fixing plate. Through the design of the elastic element, the automatic reset of the sealing plug is facilitated.

[0010] Preferably, a movable rod is movably connected to the end of the movable column. The design of the movable rod facilitates the rotation of the movable column through its action.

[0011] Preferably, both the end of the movable rod and the end of the handle are provided with anti-slip balls. The anti-slip balls at the end of the handle facilitate gripping and prevent the hand from slipping off the handle. The anti-slip balls at the end of the movable rod facilitate gripping the movable rod and prevent the movable rod from slipping off the hand, thereby facilitating the rotation of the movable column through the action of the movable rod.

[0012] Preferably, a limiting ring is fixedly connected to the movable column near the hexagonal block to limit the movable column and prevent it from detaching from the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a connecting pipe and a suction cup on a support plate. The suction cup adheres to the saw blade, aligning the rotation direction of the saw blade with that of the support plate. By applying a counter-clockwise force to the support plate using the hand grip, a counter-clockwise force can be applied to the saw blade. This avoids direct contact between the operator's hands and the saw blade, reducing the risk of hand injury and solving the problem of hand injuries that can easily occur during saw blade installation in existing technologies.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. Example

[0022] Please see Figures 1-4 A saw changing mechanism for a sawing machine includes a support plate 1, a movable column 2 mounted on the axis of the support plate 1, a hexagonal block 3 fixedly connected to the end of the movable column 2, multiple sets of connecting pipes 4 mounted on the support plate 1, suction cups 5 provided at the ends of the connecting pipes 4, and a connecting piece 6 fixedly connected to the support plate 1, a handle 7 fixedly connected to the connecting piece 6, and an air vent 8 installed at the end of the connecting pipes 4. The air vent 8 is used to release the air pressure inside the connecting pipes 4, so that the suction cups 5 are disengaged from the saw disc.

[0023] In the embodiments of this utility model, please refer to Figure 2 and Figure 3The venting component 8 shown in the figure includes a sleeve 9 fitted onto the outer side of the movable column 2. An operating block 10 fitted onto the outer side of the movable column 2 is fixedly connected to one end of the sleeve 9, and a connecting ring 11 fitted onto the outer side of the movable column 2 is fixedly connected to the other end of the sleeve 9. Multiple sets of connecting plates 12 are fixedly connected to the connecting ring 11, and a connecting column 13 is fixedly connected to the connecting plate 12. A sealing plug 14 is fixedly connected to the end of the connecting column 13. Multiple sets of sealing plugs 14 are respectively installed at the end of the connecting pipe 4. An elastic element 15 connected to the connecting pipe 4 is installed on the sealing plug 14 to facilitate the release of air pressure inside the connecting pipe 4, thereby allowing the suction cup 5 to communicate with the air, so that negative pressure cannot be generated inside the suction cup 5, thus facilitating the separation of the suction cup 5 from the saw disc.

[0024] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The elastic element 15 shown in the figure includes a fixing plate 16 fixed inside the connecting tube 4. The fixing plate 16 has several sets of through holes 17 and a sliding post 18 is slidably connected to the fixing plate 16. The sliding post 18 is fixedly connected to the sealing plug 14, and a tension spring 19 is fixedly connected between the sealing plug 14 and the fixing plate 16. Through the design of the elastic element 15, the sealing plug 14 can be automatically reset.

[0025] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 As shown in the figure, the end of the movable column 2 is movably connected to a movable rod 20. The design of the movable rod 20 makes it easy to drive the movable column 2 to rotate.

[0026] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 As shown in the figure, both the end of the movable rod 20 and the end of the handle 7 are provided with anti-slip balls 21. The anti-slip balls 21 at the end of the handle 7 make it easier to grip the handle 7 and prevent the hand from slipping off the handle 7. The anti-slip balls 21 at the end of the movable rod 20 make it easier to grip the movable rod 20 and prevent the movable rod 20 from slipping off the hand, thereby making it easier to drive the movable column 2 to rotate through the action of the movable rod 20.

[0027] In the embodiments of this utility model, please refer to Figure 2 In the diagram, a limiting ring 22 is fixedly connected to the movable column 2 near the hexagonal block 3 to limit the movable column 2 and prevent it from detaching from the support plate 1.

[0028] During the implementation process, when installing the saw blade, the saw blade is installed on the sawing machine, and then the outer flange is aligned with the sawing machine. At this time, the saw blade is located between the sawing machine and the outer flange. Then, the bolts are inserted into the axial position of the outer flange, and the outer flange is fixed by tightening the bolts, thereby fixing the saw blade between the outer flange and the sawing machine.

[0029] When tightening the bolt, the hexagonal block 3 is aligned with the bolt, and then the suction cup 5 is attached to the saw blade. During the tightening process, the handle 7 is held and a counterclockwise force is applied to the support plate 1, so that the saw blade is subjected to a counterclockwise force. At the same time, the movable rod 20 causes the movable column 2 to rotate clockwise. The rotation of the movable column 2 drives the hexagonal block 3 to rotate, which in turn drives the bolt to rotate, thereby tightening the bolt to fix the outer flange.

[0030] Furthermore, after the fixing is completed, pull the operating block 10 to make the sleeve 9 move the connecting ring 11. The movement of the connecting ring 11 causes the connecting plate 12 to move the connecting column 13, which in turn causes the sealing plug 14 to move. At this time, the end of the connecting tube 4 is connected to the air, that is, the suction cup 5 is connected to the air. At this time, the suction cup 5 cannot generate negative pressure inside, so the suction cup 5 is separated from the saw blade. Then the device can be removed to complete the installation of the saw blade.

[0031] During the movement of the sealing plug 14, the tension spring 19 is stretched, which releases the operating block 10. The tension spring 19 then causes the sealing plug 14 to reset and seal the end of the connecting pipe 4. During this process, the sliding column 18 limits the movement of the sealing plug 14, ensuring it can only move linearly.

[0032] It should be noted that during the bolt tightening process, the movable rod 20 can be moved until one of the anti-slip balls 21 contacts the movable column 2. At this time, the lever arm of the movable rod 20 increases, which makes it easier to drive the movable column 2 to rotate and tighten the bolt.
