Description

Technical Field

[0001] This utility model relates to the technical field of saw blade processing equipment, specifically to a saw blade rapid polishing machine. Background Technology

[0002] During saw blade manufacturing, the raw material needs heat treatment to improve its hardness and wear resistance. Common heat treatment methods include quenching and tempering, which densify the internal structure of the saw blade, improving cutting ability and service life. Heat-treated saw blades typically have some roughness and unevenness on the surface. To improve cutting smoothness and accuracy, polishing is necessary. Polishing makes the saw blade surface smooth and flat, reducing frictional wear during cutting.

[0003] In the prior art disclosed in CN222002989U, a saw blade surface abrasive belt grinder is described. After the saw blade body surface is polished, when the saw blade body is unloaded, the electric push rod two is controlled to rotate the connecting rod on the upright, so that the abrasive belt grinding component moves away from the saw blade body. At this time, the saw blade body placed on the pallet can be lifted by the lifting component, so that there is a gap between the saw blade body and the pallet, which facilitates the handling of the saw blade body, improves the unloading efficiency, and thus improves the work efficiency. However, the above-mentioned prior art grinder still has the following defects in the saw blade polishing process:

[0004] When polishing saw blades, the polishing process involves first grinding and polishing one side of the saw blade. After grinding and polishing one side of the saw blade, the saw blade is unloaded and the other side is loaded again so that the other side of the saw blade is on top of it and then ground and polished. The overall polishing process is quite cumbersome and reduces the efficiency of polishing saw blades.

[0005] Therefore, this application proposes a high-speed saw blade polishing machine. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a high-speed saw blade polishing machine, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0014] There are two connecting rods, which are symmetrically hinged to the top of the column on both sides via hinge axes. The free ends of the connecting rods are equipped with a sanding belt grinding assembly for grinding the surface of the saw blade body. The column is equipped with a drive mechanism that acts on the two hinge axes, which is used to make the two hinge axes rotate in opposite directions or stop rotating on the column, so that the two sets of sanding belt grinding assemblies contact the two sides of the saw blade body respectively.

[0015] Furthermore: the adjustment mechanism includes a bidirectional threaded rod that is horizontally rotatably mounted on the grinding chamber, the bidirectional threaded rod being threadedly connected to both support plates, and an electric motor for driving the bidirectional threaded rod to rotate is fixedly mounted on the grinding chamber.

The multiple rotating rollers are externally connected to the sanding belt body, and a motor is fixedly mounted on the mounting shell to drive one of the rotating rollers to rotate.

[0018] Furthermore: the drive mechanism includes two gears that are coaxially fixed to the two hinge shafts respectively, the two gears meshing, and an electric motor for driving one of the hinge shafts to rotate is fixedly installed on the column.

[0019] Furthermore: stabilizing components acting on the saw blade body are installed on the sides of the two vertical plates that are close to each other. The stabilizing components include stabilizing plates, mounting columns, and ball bearings. Horizontal stabilizing plates are fixedly installed on the vertical plates, both above and below the rotating shaft. Mounting columns are symmetrically fixedly installed on the side of the stabilizing plates away from the vertical plates. Ball bearings are ball-connected to the ends of the mounting columns. When the saw blade body is positioned by the positioning mechanism, the ball bearings contact the surface of the saw blade body.

[0020] Furthermore: a liquid storage tank with an open top is installed on the base and below the through hole. The liquid storage tank is used to store polishing liquid.

[0035] Example 1

[0036] To address the technical problems in the background section, a high-speed saw blade polishing machine is provided as follows:

[0037] Combination Figures 1-6 As shown, the present invention provides a saw blade rapid polishing machine, comprising:

[0038] Base 1;

[0039] Support frame 2 is fixedly installed on the top of base 1, and a through hole 21 is provided in the middle of support frame 2;

[0040] The grinding chamber 3 is fixedly installed on the top of the support frame 2. Support plates 31 are symmetrically slidably installed in the grinding chamber 3 in the horizontal direction. Specifically, a horizontal sliding rod is fixedly installed in the grinding chamber 3. Both support plates 31 are slidably sleeved on the sliding rod along the axis of the sliding rod. A vertical plate 32 is fixedly installed on the top of the support plate 31. A rotating shaft 33 is rotatably installed on the vertical plate 32. A positioning mechanism 4 for positioning the saw blade body 8 is installed on the two rotating shafts 33. When the saw blade body 8 is positioned by the positioning mechanism 4, the saw blade body 8 is vertical. A motor 34 for driving the rotating shaft 33 to rotate is fixedly installed on one of the vertical plates 32.

[0041] Adjustment mechanism 5 is installed on the grinding chamber 3 and is located where the two support plates 31 are connected. Adjustment mechanism 5 is used to make the two support plates 31 slide in opposite directions or stop sliding in the grinding chamber 3.

[0042] The slide rail 22 is fixedly installed on the top of the support frame 2 and located on one side of the grinding chamber 3. A column 23 is slidably installed on the top of the slide rail 22 along the direction of the grinding chamber 3. The column 23 is perpendicular to the axis of the sliding rod along the sliding direction of the slide rail 22. An electric cylinder 24 is fixedly installed on the slide rail 22 and is fixedly connected to the column 23.

[0043] There are two connecting rods 6. The two connecting rods 6 are symmetrically hinged to the top positions on both sides of the column 23 via hinge shafts 61. The free ends of the connecting rods 6 are equipped with a sanding belt grinding assembly 62 for grinding the surface of the saw blade body 8. The column 23 is equipped with a drive mechanism 7 that acts on the two hinge shafts 61. It is used to make the two hinge shafts 61 rotate in opposite directions or stop rotating on the column 23 so that the two sets of sanding belt grinding assemblies 62 contact the two sides of the saw blade body 8 respectively.

[0044] When polishing the saw blade body 8, the saw blade body 8 is loaded, causing it to move vertically between the two upright plates 32. The adjusting mechanism 5 causes the two support plates 31 to slide in opposite directions and approach each other within the grinding chamber 3. The positioning mechanism 4 positions the saw blade body 8. At this time, the driving mechanism 7 causes the two hinge shafts 61 to rotate in opposite directions on the column 23, causing the two sets of belt abrasive components 62 to contact both sides of the saw blade body 8. The belt abrasive components 62 are then controlled to polish the surface of the saw blade body 8. Finally, the electric... The cylinder 24 causes the column 23 to slide back and forth on the slide rail 22, while controlling the motor 34 to make the rotating shaft 33 rotate on the upright plate 32. This, in turn, drives the saw blade body 8 to rotate through the positioning mechanism 4. This allows the two sets of sanding belt grinding components 62 to simultaneously grind and polish both sides of the saw blade body 8. This achieves the effect of grinding and polishing both sides of the saw blade body 8 simultaneously with a single loading, eliminating the need for unloading and changing the saw blade body 8. This improves the portability, speed, and efficiency of polishing the saw blade body 8.

[0045] Example 2

[0046] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0047] In this embodiment, the adjustment mechanism 5 includes a bidirectional threaded rod 51 that is horizontally rotatably mounted on the grinding chamber 3. The bidirectional threaded rod 51 is threadedly connected to both support plates 31. A motor 52 for driving the bidirectional threaded rod 51 to rotate is fixedly mounted on the grinding chamber 3. In use, the motor 52 is turned on, and the motor 52 drives the bidirectional threaded rod 51 to rotate on the grinding chamber 3, thereby allowing the two support plates 31 to slide in opposite directions within the grinding chamber 3, moving closer or further apart, which is convenient for control.

[0048] In this embodiment, the positioning mechanism 4 includes positioning discs 41 symmetrically fixedly installed on one side of two rotating shafts 33, close to each other. One positioning disc 41 has symmetrically fixed positioning posts 411, and the other positioning disc 41 has symmetrically opened positioning holes 412. The two positioning posts 411 can be inserted into the two positioning holes 412 respectively. When the positioning posts 411 are inserted into the positioning holes 412, the outer sidewall of the positioning post 411 fits against the inner sidewall of the positioning hole 412. Specifically, the saw blade body 8 has three pre-set locking holes, and two mutually distant locking holes can be respectively fitted into two... When positioning the saw blade body 8, the saw blade body 8 is located between the two positioning discs 41 on opposite sides, and the two locking holes on the saw blade body 8 that are far apart from each other can be respectively fitted onto the outside of the two positioning discs 411. At this time, the control motor 52 makes the two support plates 31 move closer to each other, so that the two positioning discs 411 pass through the locking holes reserved on the saw blade body 8 and are respectively inserted into the two positioning holes 412, so that the two positioning discs 41 both abut against the saw blade body 8, thereby achieving the positioning effect of the saw blade body 8.

[0049] In this embodiment, the belt abrasive assembly 62 includes a mounting shell 621 fixedly installed at the end of the connecting rod 6. Multiple vertically oriented rotating rollers 622 are rotatably mounted on the mounting shell 621. One of the rotating rollers 622 is rotatably mounted at the end of the mounting shell 621 away from the connecting rod 6, and its outer periphery extends to the outside of the mounting shell 621. A belt abrasive body 623 is externally connected to the multiple rotating rollers 622. A motor 624 for driving one of the rotating rollers 622 to rotate is fixedly mounted on the mounting shell 621. During use, the motor... The drive mechanism 7 causes the two hinge shafts 61 to rotate in opposite directions on the column 23, bringing the free ends of the two connecting rods 6 closer together. This allows the rotating roller 622 located at the end of the mounting shell 621 away from the connecting rod 6 to approach the saw blade body 8, making the sanding belt body 623 fit against the saw blade body 8. The motor 624 controlling the two sets of sanding belt grinding components 62 is turned on, driving the rotating roller 622 fixed to the output shaft of the motor 624 to rotate. At this time, the other rotating rollers 622 rotate synchronously, and the sanding belt body 623 rotates around the multiple rotating rollers 622, thus achieving the grinding effect on the surface of the saw blade body 8.

[0050] Example 3

[0051] like Figures 1-6 As shown, based on the above embodiments, this embodiment further provides the following:

[0052] In this embodiment, the drive mechanism 7 includes two gears 71 that are coaxially fixed to the two hinge shafts 61 respectively. The two gears 71 mesh with each other. A second motor 72 for driving one of the hinge shafts 61 to rotate is fixedly installed on the column 23. In use, the second motor 72 is turned on, and the output shaft of the second motor 72 rotates, driving the hinge shaft 61 fixed to it to rotate. When the hinge shaft 61 rotates, it drives the gear 71 fixed to it to rotate, so that the other hinge shaft 61 can be driven to rotate in the opposite direction through the other gear 71.

[0053] In this embodiment, stabilizing components 9 acting on the saw blade body 8 are installed on the sides of the two upright plates 32 that are close to each other. The stabilizing components 9 include stabilizing plates 91, mounting columns 92, and ball bearings 93. Horizontal stabilizing plates 91 are fixedly installed on the upright plates 32 above and below the rotating shaft 33. Mounting columns 92 are symmetrically fixedly installed on the side of the stabilizing plates 91 away from the upright plates 32. The ends of the mounting columns 92 are ball-connected to the ball bearings 93. When the saw blade body 8 is positioned by the positioning mechanism 4, the ball bearings 93 contact the surface of the saw blade body 8. By setting the stabilizing components 9, when the saw blade body 8 is polished, the ball bearings 93 contact the saw blade body 8, thereby achieving the effect of limiting the eccentric part of the saw blade body 8 by the four ball bearings 93 on the two sets of stabilizing components 9, improving the stability of the saw blade body 8 during polishing. Furthermore, when the saw blade body 8 rotates around the rotating shaft 33, the multiple ball bearings 93 roll on the surface of the saw blade body 8 without affecting the rotation of the saw blade body 8 around the rotating shaft 33.

[0054] In this embodiment, a liquid storage tank 11 with an open top is installed on the base 1 below the through hole 21. The liquid storage tank 11 is used to store polishing liquid. A spray pipe 625 is fixedly installed on the mounting shell 621. Specifically, when the abrasive belt body 623 is in contact with the saw blade body 8, the liquid outlet of the spray pipe 625 points to the contact point between the abrasive belt body 623 and the saw blade body 8. A liquid passage pipe 626 connected to the spray pipe 625 is fixedly installed on the connecting rod 6. A pipe connected to the inner bottom wall of the liquid storage tank 11 is fixedly installed on the base 1. The liquid pump 12 has its outlet end connected to the liquid pipe 626 via a connecting hose 121. By setting up a storage tank 11, a liquid pump 12, and a spray pipe 625, when polishing the saw blade body 8, the polishing liquid is poured into the storage tank 11 for storage. The liquid pump 12 is controlled to work, and the polishing liquid in the storage tank 11 is drawn out and transported to the liquid pipe 626 through the connecting hose 121. Then, it is sprayed out through the spray pipe 625 to the contact point between the sanding belt body 623 and the saw blade body 8, which is beneficial for grinding and polishing the saw blade body 8.

[0055] In this embodiment, the grinding chamber 3 has a drain hole 35 at its bottom that communicates with the through hole 21. The inner wall of the storage tank 11 has a slot 111 that communicates with its open end. The bottom end of the slot 111 extends to the middle of the inner wall of the storage tank 11. A filter plate 112 for sealing the open end of the storage tank 11 is inserted into the slot 111. Specifically, the filter plate 112 has a side with the largest surface area. When the filter plate 112 is inserted into the slot 111, the side with the largest surface area of ​​the filter plate 112 seals the open end of the storage tank 11. The side with the largest surface area of ​​the filter plate 112 has several openings, each with a [missing information - likely a number of openings]. The filter holes in the vertical direction and through the filter plate 112, through the drain hole 35 and the filter plate 112, the polishing liquid is sprayed out through the spray pipe 625 to the place where the sanding belt body 623 and the saw blade body 8 are in contact. The polishing liquid waste liquid after grinding and polishing will flow along the saw blade body 8 and fall to the bottom wall of the grinding chamber 3, and then flow down through the drain hole 35 into the storage tank 11. When the polishing liquid waste liquid flows back into the storage tank 11, it comes into contact with the filter plate 112. The filter plate 112 filters the polishing liquid waste liquid before it flows back into the storage tank 11, so that it can be extracted by the liquid pump 12 for reuse, which is conducive to the recycling of polishing liquid.
