Description

Technical Field

[0001] The invention relates to the technical field of tool edge grinding, and in particular to a cemented carbide tool edge grinding device. Background Art

[0002] Carbide tools are cutting tools made of a combination of multiple metals. They have high hardness and good wear resistance. According to different usage scenarios, they can be divided into milling cutters and circular cutters. Circular cutters need to use carbide tool edge grinding equipment to grind the cutting edge of circular cutters during production and after a long period of use.

[0003] The Chinese utility model with authorization announcement number CN218927170U discloses a circular tool sharpener, including a large circular tool chassis and a hand crank handle B, a shutter is installed on the outer wall of the large circular tool chassis, a protective frame is installed above the large circular tool chassis, and a fixed support plate is provided on the upper surface of the large circular tool chassis.

[0004] In the above-mentioned prior art, the screw can be driven to rotate by rotating the hand crank B, thereby driving the motor base to move on the surface of the fixed seat, thereby effectively solving the problems and shortcomings of the existing device. However, in the process of grinding the edge of the circular tool, the cutting edge of the circular tool is generally ground from a certain angle by a grinding wheel such as a grinding wheel, which may cause the material at the cutting edge to be squeezed to the bottom of the cutting edge to form burrs, and these burrs may cause the cutting effect of the circular tool to decrease during subsequent use, thereby affecting normal use.

[0031] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0033] Then, driving device 2 drives the notched disk and the discharge part to rotate, and the fitting wheel descends with the movement of the notched part of the notched disk, thereby driving piston rod 2 to descend in the inner cavity of piston cylinder 2, thereby squeezing the air in the inner cavity of piston cylinder 2 into the inner cavity of piston cylinder 1 along the connecting pipe and the one-way air inlet valve, causing piston rod 1 in the inner cavity of piston cylinder 1 to descend a short distance, which resets spring assembly 1, and spring assembly 1 no longer provides elastic force to deburring assembly 1.

[0065] Embodiment 2, as Figure 1-Figure 6 As shown, a cemented carbide tool edge grinding device proposed by the present invention, compared with the first embodiment, the locking mechanism in this embodiment includes a discharge portion 24, a support member 25, a spring third 26, a pull ring 27, a locking rod 28, a fixing ring 29, a spring assembly second 30, a movable plate 31, a rotating plate 32 and a locking portion;

[0066] The discharge part 24 is connected to the notched disk 23, and a groove is provided in the discharge part 24, into which the locking part is inserted; the support member 25 is installed on the outer side of the piston cylinder 9; the spring three 26 is sleeved on the outer periphery of the locking plug rod 28, and the two ends of the spring three 26 are respectively connected to the support member 25 and the pull ring 27; the pull ring 27 is connected to the locking plug rod 28; the locking plug rod 28 passes through the support member 25 and is connected to the locking part; the locking plug rod 28 is installed with a fixing ring 29, and the fixing ring 29 is installed with three spring assemblies two 30, and the three spring assemblies two 30 are all sleeved on the outer periphery of the locking plug rod 28; the spring assembly two 30 is connected to the movable plate 31, the movable plate 31 is rotatably connected to the rotating plate 32, and the movable plate 31 and the rotating plate 32 both slide on the locking plug rod 28;

[0067] Pull the pull ring 27 to make the locking part leave the groove and place the circular cutter close to the discharge part 24. Then release the pull ring 27. The elastic force of spring three 26 drives the locking part to pass through the center hole of the circular cutter and return to the groove to lock and fix the circular cutter. The rotating plate 32 is tightly fitted with the circular cutter under the elastic force of spring component two 30.

[0068] Embodiment three, as Figure 1-Figure 5As shown, a cemented carbide tool edge grinding device proposed by the present invention, compared with the second embodiment, the spray mechanism in this embodiment includes a telescopic tube 1 33, a telescopic tube 2 34, a spray pipe 35, a telescopic rod 1 36, a telescopic rod 2 37, an L-shaped rod 38 and a conveying device 40;

[0069] The L-shaped rod 38 is installed on the lifting part 12, and the L-shaped rod 38 is connected to the telescopic rod 2 37, and the telescopic rod 2 37 is connected to the spray pipe 35, and the spray pipe 35 can move horizontally along the axis direction of the telescopic rod 2 37; the spray pipe 35 is connected to the telescopic rod 1 36, and the two ends of the telescopic rod 1 36 are respectively connected to the movable plate 31 and the spray pipe 35, and the spray pipe 35 can move vertically along the axis direction of the telescopic rod 1 36; the spray pipe 35 is connected to the telescopic pipe 2 34, and the telescopic pipe 2 34 is connected to the telescopic pipe 1 33. The telescopic pipe 1 33 is installed with a conveying device 40, and the conveying device 40 is a water pump. Before use, the conveying pipeline of the external coolant is connected to the input end of the conveying device 40;

[0070] The rotating plate 32 drives the spray pipe 35 to move horizontally through the telescopic rod 1 36, and the spring component 11 drives the spray pipe 35 to move up and down through the telescopic rod 2 37, so that the spray pipe 35 is always close to the grinding edge of the circular tool.

[0071] In summary, in the present invention, the pull ring 27 is pulled to drive the locking portion at one end of the locking rod 28 to leave the groove of the discharge portion 24, and then the circular tool is placed between the rotating plate 32 and the discharge portion 24 from top to bottom. At this time, the bottom of the circular tool will contact the deburring component 13, and the side of the circular tool will contact the deburring component 2 14. The bottom of the circular tool will contact the deburring component 13. As the circular tool descends, the lifting part 12 is forced to descend. At this time, the spring component 11 contracts first, and after the spring component 11 is fully contracted, it drives the piston rod 18 to move inside the piston cylinder 19. The cavity descends, and as the piston rod 8 descends in the inner cavity of the piston cylinder 9, the external air will enter the piston cylinder 17 through the ventilation pipe 18, and then enter the part of the inner cavity of the piston cylinder 9 located above the piston rod 8 through the piston cylinder 17, the connecting pipe 15 and the one-way air intake valve 16. Since the one-way air intake valve 16 cannot discharge the air in the inner cavity of the piston cylinder 9, the position of the piston rod 8 is temporarily fixed after the inner cavity of the piston cylinder 9 descends, and at this time, the deburring component 13 is subjected to the elastic force of the spring component 11 and is squeezed toward the bottom of the circular tool.

[0072] As the height of the lifting part 12 changes, the lifting part 12 drives the L-shaped rod 38 to descend, and the L-shaped rod 38 drives the height of the spray pipe 35 to change through the telescopic rod 2 37 .

[0073] Next, align the center hole of the circular cutter with the groove of the discharge part 24, then loosen the pull ring 27, and drive the locking part at one end of the locking rod 28 through the center hole of the circular cutter and insert it into the groove of the discharge part 24 through the elastic force of the spring three 26. At the same time, the movable plate 31 is driven by the elastic force of the spring component two 30 to drive the rotating plate 32 to fit tightly with the circular cutter.

[0074] When fixing circular cutters of different thicknesses, the position of the movable plate 31 when fixing the circular cutter is changed compared to the position in the initial state, and the movable plate 31 drives the lateral position of the spray pipe 35 to change through the telescopic rod 36, thereby realizing the combination of the lifting part 12 and the movable plate 31, so that the spray pipe 35 is always close to the grinding edge of the circular cutters of different sizes and thicknesses, so that there is no need to manually adjust the spray pipe 35 to align with the grinding edge, and because only the grinding edge of the circular cutter can be sprayed and cooled more accurately, the amount of coolant used is reduced, which has good economy.

[0075] After the circular tool is fixed, the angle of the rotating seat 5 is adjusted as needed, thereby adjusting the angle of the circular tool, and then the position of the driving device 1 3 is adjusted by moving the base 2, and then the driving device 1 3 is started to drive the grinding wheel 4 to rotate to grind the circular tool, and at the same time, the driving device 2 7 is started to drive the circular tool to rotate.

[0076] When the driving device 27 is started, the notched disk 23 and the discharge part 24 will be driven to rotate. Since the movable plate 31 and the rotating plate 32 are rotatably connected, and the rotating plate 32 is subject to the elasticity of the spring assembly 230, the movable plate 31 fits tightly with the circular cutter, so that when the driving device 27 drives the discharge part 24 to rotate, it can also drive the circular cutter to rotate.

[0077] When the notch disk 23 rotates, the notch is driven to rotate, and the fitting wheel 22 descends along the notch of the notch disk 23 with the piston rod 21 as the axis, thereby driving the piston rod 21 to descend in the inner cavity of the piston cylinder 17 over the ventilation pipe 18, and the air in the inner cavity of the piston cylinder 17 is squeezed into the inner cavity of the piston cylinder 19 along the connecting pipe 15 and the one-way air intake valve 16. At this time, the part of the inner cavity of the piston cylinder 17 below the piston rod 21 is in a negative pressure state, which makes it impossible to reset automatically.

[0078] The air entering the inner cavity of the piston cylinder 9 causes the piston rod 8 to drop a certain distance, and at this time the spring assembly 11 is reset, and the deburring assembly 13 is not subjected to the elastic force of the spring assembly 11, so that it naturally fits the bottom of the circular tool. Then the deburring assembly 13 and the deburring assembly 2 14 are started to rotate, and the deburring assembly 2 14 removes the burrs on the side of the circular tool, and the deburring assembly 13 removes the burrs on the bottom of the circular tool;

[0079] Thereby, the deburring component 13 and the deburring component 2 14 can be changed in position according to circular cutters of different sizes, which is quick and convenient. The deburring component 13 can be fitted to the bottom of the circular cutter to effectively remove burrs while avoiding the deburring component 13 from being squeezed against the bottom of the circular cutter, resulting in the bottom of the circular cutter being subjected to more force and not being sharp enough.

[0080] After the edge grinding is completed, the notched disk 23 is reset, the circular tool is removed, and the control valve 39 is started to make the upper part of the inner cavity of the piston cylinder 9 connected with the outside. At this time, the elasticity of the spring 10 drives the piston rod 8, the spring assembly 11 and the lifting part 12 to reset, and then the control valve 19 is started to allow the external air to enter the inner cavity of the piston cylinder 17, thereby relieving the negative pressure state of the inner cavity of the piston cylinder 17, and then the elasticity of the spring 20 drives the piston rod 21 to move upward and reset.

[0081] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
