After processing, the equipment needs to be stopped for a long time so that the user can replace the cutting tool, which is time-consuming, labor-intensive, and affects the processing efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a repositionable cutting tool grinding device, including a support;

[0008] The top of the bracket is movably connected to a transmission rod via a bearing. Extension plates are fixedly connected to all four sides of the transmission rod.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1 to 6 As shown, the present invention provides an indexable blade sharpening device, including a support 1;

[0034] The top of the bracket 1 is movably connected to the transmission rod 2 via a bearing. Extension plates 3 are fixedly connected around the transmission rod 2. Insert rods 4 are fixedly connected to both sides of the surface of the extension plates 3. The blade workpiece 5 is sleeved on the surface of the insert rods 4. The transmission rod 2 can rotate the blade workpiece 5 by using the extension plates 3. A grinding component is provided at the bottom inside the bracket 1. The grinding component can grind the blade workpiece 5 below.

[0035] refer to Figure 3 The grinding assembly includes a crossbeam 6 fixedly connected to the inside of the bracket 1. An electric telescopic rod 7 is fixedly connected to the top of the crossbeam 6. A bearing plate 8 is fixedly connected to the output end of the electric telescopic rod 7. A polishing pulley 9 is fixedly installed on the surface of the bearing plate 8. The outer surface of the polishing pulley 9 is in contact with the surface of the blade workpiece 5.

[0036] As a technical optimization of this utility model, the bearing plate 8 and polishing pulley 9 are driven to move vertically by the electric telescopic rod 7. The controllable pressure ensures the uniformity of the blade surface grinding. At the same time, the polishing pulley 9 directly contacts the blade, eliminating the need for a complex transmission mechanism and reducing the failure rate and maintenance costs.

[0037] refer to Figure 3 A support plate 10 is provided on the top of the crossbeam 6. The side of the support plate 10 away from the crossbeam 6 extends to the back of the blade workpiece 5 below. The support plate 10 can support the blade workpiece 5 which is squeezed by the polishing pulley 9.

[0038] As a technical optimization of this utility model, the support plate 10 abuts against the back of the blade to resist the deformation caused by polishing pressure and ensure processing accuracy. Moreover, the support plate 10 automatically switches positions with the grinding station to adapt to the needs of multi-station rotating structures.

[0039] refer to Figure 3 Guide rods 11 are fixedly connected to both sides of the top of the crossbeam 6, and the support plate 10 is sleeved on the surface of the guide rods 11 and slidably connected to the guide rods 11.

[0040] As a technical optimization of this utility model, the guide rod 11 constrains the movement path of the support plate 10 to avoid skewing and ensure that the supporting force acts perpendicularly on the blade.

[0041] refer to Figure 3 Both sides of the bearing plate 8 are movably connected to the crank 12 by pins. The side of the crank 12 away from the bearing plate 8 extends to the outside of the support plate 10 and is movably connected to the support plate 10 by pins.

[0042] As a technical optimization of this utility model, the bearing plate 8 and the support plate 10 are hinged by the crank 12, so that the two move forward and backward synchronously with the electric telescopic rod 7, thereby improving the support response efficiency.

[0043] refer to Figure 5 The outer end of the transmission rod 2 passes through the bracket 1 and extends to the outside of the bracket 1. An intermittent rotating component is provided at the outer end of the transmission rod 2.

[0044] As a technical optimization of this utility model, the end of the external transmission rod 2 of the intermittent rotating component is spatially separated from the processing area, thus avoiding interference from grinding debris.

[0045] refer to Figure 5 The intermittent rotating component includes a ratchet 13 fixedly connected to the outside of the transmission rod 2. A pawl assembly 14 is provided on the rear side of the bottom of the ratchet 13. The pawl assembly 14 is connected to the support plate 8 through a linkage structure. During the forward and backward movement of the support plate 8, the linkage structure can be used to carry the pawl assembly 14 to squeeze the ratchet 13.

[0046] As a technical optimization of this utility model, the pawl is directly driven to push the ratchet 13 by the reciprocating motion of the bearing plate 8, which transforms the grinding action into the indexing power of the workstation without the need for an additional motor.

[0047] refer to Figure 5 The linkage structure includes a fixed plate 15 fixedly connected to the surface of the bearing plate 8. Both sides of the fixed plate 15 are fixedly connected to upright plates 16. The side of the upright plate 16 away from the fixed plate 15 extends to the outside of the pawl assembly 14 and is connected to the pawl assembly 14.

[0048] As a technical optimization of this utility model, a sturdy frame is formed by the fixed plate 15 and the upright plate 16, which efficiently transmits the power of the bearing plate 8 to the pawl and reduces energy loss.

[0049] The working principle and usage process of this utility model are as follows: The operator places the blade workpiece 5 to be sharpened onto the insertion rods 4 on both sides of multiple extension plates 3. Since multiple extension plates 3 are distributed around the circumference of the transmission rod 2, blade workpieces 5 can be loaded at multiple workstations at once. After the equipment is started, the sharpening assembly located at the bottom inner side of the support 1 begins to work. The electric telescopic rod 7 drives the bearing plate 8 and its polishing pulley 9 to move backward, so that the outer surface of the polishing pulley 9 presses against and contacts the surface of the blade workpiece 5 currently located directly behind it. The support plate 10 moves synchronously to the back of the blade workpiece 5 under the pushing guidance of the crank 12, providing support force to ensure the sharpening process is completed. To ensure the stability of the process, the polishing pulley 9 starts to rotate and re-grinds the blade at the first station. After the blade at the first station is re-grinded, the electric telescopic rod 7 controls the bearing plate 8 and the polishing pulley 9 to retract. During this process, the movement of the bearing plate 8 drives the upright plates 16 on both sides through the fixed plate 15 connected to its surface. The upright plates 16 drive the pawl assembly 14 connected to them. The pawl assembly 14 pushes the ratchet 13 fixed at the end of the transmission rod 2 to rotate by one tooth angle, so that the blade workpiece 5 loaded on the next station moves to the re-grinding position. Then the above re-grinding operation is repeated, which can realize the rotational processing operation of the blades at all stations.

[0050] In summary, this indexable blade sharpening equipment, by setting multiple extension plates 3 and plug-in rods 4 distributed circumferentially on the transmission rod 2, can simultaneously load multiple blade workpieces 5, breaking through the limitations of single-station processing. At the same time, the transmission rod 2 drives the blade to rotate and switch stations, so that the equipment does not need to stop to change materials during processing, significantly improving efficiency.
