Description

Technical Field

[0001] The utility model belongs to the technical field of saw blade processing equipment and relates to a saw blade polishing device. Background Art

[0002] To improve the surface quality of steel saw blades or enhance the aesthetics of saw blades, saw blades need to be polished before leaving the factory, and both sides of the saw blades need to be polished. Therefore, enterprises need to set up dedicated polishing equipment.

[0003] The patent with the application publication number CN111843046A discloses an integrated automatic production line for diamond saw blade polishing, painting, and drying. It includes a loading tray, a moving mechanism, a frame, a polishing device, a blanking manipulator, and a blanking tray. The moving mechanism on the frame is provided with a loading manipulator, a flipping manipulator, and a transfer manipulator. The moving mechanism where the loading manipulator, flipping manipulator, and transfer manipulator are located has three stations. The loading manipulator moves from the loading station to the first polishing station, the flipping manipulator moves from the first polishing station to the second station, and the transfer manipulator moves from the second polishing station to the blanking station synchronously with the moving mechanism.

[0004] The above production line can achieve double-sided polishing of saw blades, but there are still deficiencies: the flipping of the saw blade is realized by the flipping manipulator rotating after clamping the saw blade. Since the saw blade is relatively thin, clamping the edge of the saw blade by a conventional manipulator easily causes excessive force on the local contact position and damages the cutting head. Summary of the Invention

[0005] Aiming at the above problems existing in the prior art, the utility model provides a saw blade polishing device. The technical problem to be solved by the utility model is that the existing saw blade polishing device is prone to damage the saw teeth.

[0006] The purpose of the utility model can be achieved by the following technical solutions:

[0007] A saw blade polishing device includes a workbench. A horizontally arranged truss is fixedly provided on the workbench. A plurality of suction cups are slidably connected to the truss at uniform intervals and can move synchronously along the length direction of the truss. The suction cups are arranged downward. A front polishing device and a back polishing device are arranged on the workbench at intervals along the length direction of the truss. It is characterized in that a flipping bracket is arranged on the workbench between the front polishing device and the back polishing device. A lifting seat that can move up and down is connected to the flipping bracket. A rotating seat is rotatably connected to the lifting seat. The rotation axis of the rotating seat is horizontally arranged and perpendicular to the truss. Two clamping arms that horizontally extend towards the side where the truss is located and can reciprocate towards each other are connected to the rotating seat. The opposite sides of the two clamping arms are both concave arc-shaped. The front polishing device, the back polishing device, and the clamping arms are respectively opposite to different suction cups.

[0008] The truss on the workbench can stably guide the synchronous movement of multiple suction cups. The multiple suction cups can suck the saw blades at different workstations and transfer them synchronously when moving. The structures of the front polishing device and the back polishing device are the same as those of existing polishing equipment and can realize the polishing process of the saw blades. By setting a flipping bracket on the workbench between the front polishing device and the back polishing device, connecting a lifting seat to the flipping bracket, connecting a rotating seat to the lifting seat and setting a clamping arm that can reciprocate in opposite directions on the rotating seat, the concave arc shape is formed on the opposite side of the two clamping arms. At the same time, the front polishing device, the back polishing device and the clamping arms are respectively opposite to different suction cups. In this way, the suction cup can drive the saw blade that has completed front polishing to be translated to the two clamping arms. The two clamping arms can keep open and be driven by the lifting seat to rise to the position of the saw blade, and then clamp the edge of the saw blade from both horizontal sides. After that, the suction cup retracts and the rotating seat drives it to rotate 180 degrees to achieve flipping. Finally, the clamping arms open and are sucked by another suction cup and transferred to the back polishing station. During this process, the side of the two clamping arms in contact with the edge of the saw blade is in a concave arc shape and can be adapted to the outer diameter arc of the saw blade, thereby increasing the clamping contact area, avoiding excessive local stress on the cutting heads at the edge of the saw blade and being damaged. At the same time, the mechanisms for transferring the saw blade on the truss are all suction cups, which are convenient for unified setting and the suction cups can better reduce the contact damage of the cutting heads at the edge of the saw blade, effectively ensuring the processing quality of the saw blade.

[0009] In the above saw blade polishing equipment, the opposite sides of the two clamping arms are both provided with strip-shaped positioning grooves arranged along the length direction of the clamping arms. In this way, when the two clamping arms clamp the saw blade, the edge of the saw blade can be embedded in the positioning grooves, making the position of the saw blade more stable. At the same time, it is beneficial to maintain the clamping effect of the saw blade under the condition of reducing the clamping force of the clamping arms, thereby avoiding excessive stress on the cutting heads at the edge of the saw blade and further ensuring the processing quality of the saw blade.

[0010] In the above saw blade polishing equipment, the open edges of the positioning grooves are processed with chamfer transitions. In this way, when the two clamping arms clamp the saw blade, even if there is a certain position error, the edge of the saw blade can smoothly embed into the positioning grooves along the chamfered surface of the open edge of the positioning grooves, avoiding the cutting heads being damaged due to excessive stress when the edge of the saw blade does not directly embed into the positioning grooves during the clamping process.

[0011] In the above-mentioned saw blade polishing equipment, the suction cup can move up and down relative to the truss. Two storage turntables are rotatably connected to the workbench. The rotation axis of the storage turntable is vertically arranged. At least two positioning columns are vertically arranged on the storage turntable and are evenly spaced along the circumferential direction of the storage turntable. The two storage turntables are respectively arranged at both ends of the truss and are close to the edge of the workbench. The suction cup at the end of the truss is vertically aligned with one of the positioning columns. This is conducive to stacking and sleeving multiple saw blades on the positioning columns on the storage turntable to achieve centralized loading and unloading, improve the efficiency and convenience of loading and handling, and at the same time improve the space utilization rate. The suction cup can ensure the stable transfer of the saw blade by lifting to grab and place the saw blade.

[0012] In the above-mentioned saw blade polishing equipment, the suction cup is an electromagnet component. The electromagnet component can conveniently control the magnitude of the adsorption force, and is more stable and reliable than vacuum adsorption, avoiding damage to the saw blade due to vibration and falling.

[0013] In the above-mentioned saw blade polishing equipment, a front surface fine polishing device, a back surface fine polishing device and two laser cleaning devices are also provided on the workbench. The front surface polishing device, one of the laser cleaning devices, the front surface fine polishing device, the flipping bracket, the back surface polishing device, the other laser cleaning device, and the back surface fine polishing device are arranged in sequence along the length direction of the truss and are respectively opposite to different suction cups. The front surface fine polishing device, the back surface fine polishing device and the laser cleaning device are all existing equipment. In this way, after the saw blade is polished by the front surface polishing device, it can be first subjected to non-contact surface cleaning by the laser cleaning device to remove surface oil stains and impurities, and then subjected to higher-precision polishing processing by the front surface fine polishing device. The same is true for the back surface polishing, which is conducive to improving the polishing quality of the saw blade.

[0014] Compared with the prior art, the advantages of the present utility model are as follows:

[0015] In the present saw blade polishing equipment, the sides of the two clamping arms in contact with the edge of the saw blade are both concave arc-shaped and can be adapted to the outer diameter arc of the saw blade, thereby increasing the clamping contact area, avoiding excessive local stress on the cutting head at the edge of the saw blade and being damaged. At the same time, the mechanisms for transferring the saw blade on the truss are all suction cups, which are convenient for unified setting and the suction cup can better reduce the contact damage to the cutting head at the edge of the saw blade during the transfer process.

A rotating seat 13 is rotatably connected to the lifting seat 12. The rotating seat 13 is driven by a motor. The rotation axis of the rotating seat 13 is horizontally arranged and perpendicular to the truss 2. Two clamping arms 14 that horizontally extend toward the side where the truss 2 is located and can reciprocate in opposite directions are connected to the rotating seat 13. The two clamping arms 14 are driven by an existing cylinder arranged on the rotating seat 13. The opposite sides of the two clamping arms 14 are both concave arc-shaped.

Specifically, both of the opposite sides of the two clamping arms 14 have strip-shaped positioning grooves 141 arranged along the length direction of the clamping arms 14, and the open edges of the positioning grooves 141 are chamfered.

[0024] As Figure 1As shown in the figure, the suction cup 3 can be driven by a cylinder to move up and down relative to the truss 2. There are also two storage turntables 6 rotatably connected to the workbench 1.

At least two positioning columns 61 are vertically arranged on the storage turntable 6 and are evenly spaced along the circumferential direction of the storage turntable 6. The two storage turntables 6 are respectively used for loading and unloading. The two storage turntables 6 are respectively arranged at both ends of the truss 2 and close to the edge of the workbench 1. The suction cup 3 at the end of the truss 2 is vertically aligned with a positioning column 61.
