Description

Technical Field

[0001] The present invention relates to the technical field of fixture devices, and in particular to a fixture device and a method for drilling bit processing. Background Art

[0002] The drill bit is a common tool in CNC machining. It can drill holes on the surface of the workpiece through the tool marks on the surface while being driven by the motor to rotate at high speed. It has a wide range of uses and can be used on drilling machines, lathes, milling machines, electric drills and other machine tools. It is currently a common type of machining tool.

[0003] During the production process of the drill bit, the steel used is generally hard, so it will be milled or rolled and then quenched, tempered and heat treated before being ground. Therefore, during the drill bit manufacturing process, the fixture used must also meet strong stability and energy absorption effects to ensure the normal processing of the drill bit.

[0004] The current fixture for clamping drill bits cannot meet the requirements of fully automatic feeding during actual use. The fixture can only provide the effect of clamping the blank steel. Therefore, after processing the front end drill bit, the fixture needs to be manually loosened, and then the blank is pushed forward by the feeding component. As a result, more equipment is required as a whole, resulting in high cost. The automation and integration of the fixture are low, which affects the actual processing efficiency.

[0005] Therefore, how to provide a clamp device and method for drill bit processing is a problem that those skilled in the art urgently need to solve. Summary of the invention

[0010] The transmission tooth is fixed at one end of the turbine rod, and the transmission tooth is located directly above the clutch tooth. The clamping seat moves through the clamping mechanism to drive the clutch tooth to engage with the transmission tooth, and the rotation of the transmission tooth drives the driving wheel to rotate.

[0011] Furthermore, the separation transmission mechanism includes a toothed disc and clutch teeth, the toothed disc is fixed to the output shaft of the actuator motor through a gear below, the actuator motor is fixed to the base, and the toothed disc is rotatably mounted in the base through a limit seat.

[0012] Furthermore, two groups of oppositely distributed engaging blocks are fixedly connected to a surface of one side of the clamping seat close to the clutch teeth, the outer clamping convex ring and the engaging blocks are located in the same vertical plane direction, and the engaging blocks are butt-engaged with the surface of the outer clamping convex ring.

[0013] Furthermore, the transmission teeth and the inner meshing convex ring are located at the same horizontal height, the clutch teeth can mesh with the inner meshing convex ring and the transmission teeth at the same time, and the vertical positions of the transmission teeth and the outer clamping convex ring are staggered with each other.

[0014] Furthermore, the pushing mechanism includes a turbine rod and a vortex gear, the turbine rod and the vortex gear are engaged for transmission, the turbine rod is movably mounted in the rotating sleeve mold through a side plate, and the left and right sides of the vortex gear are respectively fixedly connected with side teeth through a connecting rod.

[0015] Furthermore, the rotating sleeve mold is provided with a side plate near the side teeth, and the side plate is provided with driving teeth on the left and right sides near the side teeth, respectively. The driving teeth are meshed with the side teeth, and the driving wheel is fixed on the opposite sides of the two groups of driving teeth through a connecting shaft.

[0016] Furthermore, the clamping mechanism includes an active motor and a telescopic frame, the output end of the active motor is fixedly connected to a double-ended threaded rod, the left and right sides of the double-ended threaded rod are respectively threadedly connected to transmission blocks, and the threaded connection directions of the two sets of transmission blocks and the double-ended threaded rod are opposite.

[0017] Furthermore, the telescopic frame is a four-sided movable frame, and two sides of the telescopic frame are movably connected to two groups of transmission blocks through shaft pins.

[0018] Furthermore, the upper and lower sides of the telescopic frame are movably connected to the support pins through the shaft holes, the support pins are fixed to the side faces of the clamping seat, and the surface of the clamping seat is slidably connected to the rotating sleeve mold through the sliding rod.

[0019] A method for using a fixture for drilling processing comprises the following steps:

[0020] S1. First, the active motor drives the double-end threaded rod to rotate. Due to the different threaded connection directions of the two sets of transmission blocks, the two sets of transmission blocks are limited by the rotating sleeve die and approach each other on the surface of the double-end threaded rod, pushing the telescopic frame to deform. The telescopic frame pushes the two sets of clamping seats away from each other inside the rotating sleeve die to provide a space for the blank to pass through. Then, the blank is passed through between the two sets of driving wheels, providing a basic stabilization effect under the resistance of the driving wheels. At the same time, the clamping seat can drive the clutch teeth to engage with the transmission teeth and the internal convex ring.

[0021] S2, at this time, the motor is driven, and the gear plate is directly engaged with the gear plate to rotate. One side of the gear plate drives the clutch gear to rotate through the inner meshing convex ring. Under the transmission effect, the transmission teeth are driven by the clutch gear to rotate, thereby realizing the rotation of the turbine rod. The lower part of the turbine rod is engaged with the volute gear, so that the volute gear can drive the side teeth on both sides to rotate through the connecting rod, and the side teeth are engaged with the two sets of driving teeth, so that the driving teeth can directly drive the two driving wheels to rotate in the same direction, pushing the blank to move to one side;

[0022] S3, after the blank is moved to the specified position, the active motor drives in reverse to drive the two groups of clamping seats to approach each other until the surface of the clamping seats clamps the blank. As the two groups of clamping seats approach each other, the clutch teeth and the transmission teeth and the inner convex ring can be driven to disengage, and at the same time, the meshing block on one side of the clamping seat can be engaged with the outer convex ring on one side of the gear disc, and then the blank can be normally cut and washed;

[0023] S4. After cleaning, start the execution motor again to rotate the gear disc. Since the outer clamping convex ring and the meshing clamping block are locked with each other, the rotation effect of the gear disc will directly drive the two sets of clamping seats to rotate, and the rotating sleeve die will also rotate above the base, thereby changing the rotation angle of the blank and providing a wider cleaning space.

[0024] The beneficial effects of the present invention are:

[0025] The present invention provides a pushing mechanism, which can drive the pushing wheel to rotate on the upper and lower sides of the blank, and push the blank to one side, so as to achieve the feeding effect. The driving mechanism is driven to operate under the setting of the transmission teeth, and the transmission teeth are connected with the inner meshing convex ring through the clutch teeth, so that the transmission purpose with the execution motor can be directly achieved, and the automatic feeding effect of the equipment is met.

[0026] The clamping mechanism of the present invention can drive the two groups of clamping seats to move closer to or farther from each other under the drive of the active motor, so as to clamp or release the blank, and meet the clamping purpose under normal conditions. After the two groups of clamping seats move towards each other to clamp the blank, the meshing block can also be engaged with the outer clamping convex ring. At this time, the rotation effect of the toothed disc can directly drive the clamping seat to rotate, thereby driving the blank to rotate at an angle as a whole, thereby increasing the actual processing range and enhancing the processing flexibility.

[0027] The clutch teeth and the meshing block provided in the present invention can respectively drive the clutch teeth to engage with the internal meshing cam and the transmission teeth when the clamping mechanism drives the clamping seat to move. At this time, the clamping seat releases the clamping of the blank, and the pushing mechanism can drive the pushing wheel to rotate. Conversely, the clutch teeth, the vortex teeth and the internal meshing cam are released. At this time, the meshing block engages with the external meshing cam. The rotation effect of the toothed disc drives the rotation of the blank, so that the transmission of the toothed disc is controlled by the clamping mechanism, which meets different driving effects. The degree of automation is high, the equipment is relatively integrated, and the production efficiency can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0040] refer to Figure 1-8 , including a rotating sleeve die 2 movably mounted on the top of the base 1 through a shaft sleeve, two groups of clamping seats 3 are slidably arranged in the rotating sleeve die 2, and clamping mechanisms 9 are respectively arranged on both sides of the rotating sleeve die 2 near the clamping seats 3. The clamping mechanisms 9 drive the two groups of clamping seats 3 to move towards each other to clamp the blank 4. The end of the base 1 near the rotating sleeve die 2 is rotated by the execution motor 5 and is provided with a separation transmission mechanism 6;

[0041] Two sets of driving wheels 8 are movably mounted on the upper and lower sides of the rotating sleeve die 2 through a driving mechanism 7, and the driving wheels 8 are located on the inner side of the clamping seat 3, and the blank 4 is located on the opposite side of the two sets of driving wheels 8. The driving wheels 8 rotate to drive the blank 4 to move to one side;

[0042] The clutch tooth 65 is arranged on the side of the clamping seat 3 close to the toothed disc 61 through the coupling shaft. The inner and outer rings of the toothed disc 61 are respectively fixed with an inner meshing convex ring 62 and an outer clamping convex ring 63. The clamping seat 3 is moved by the clamping mechanism 9 to drive the clutch tooth 65 to mesh with the inner meshing convex ring 62.

[0043] Transmission tooth 75 is fixed at one end of turbine rod 71 . Transmission tooth 75 is located directly above clutch tooth 65 . Clamping seat 3 moves through clamping mechanism 9 to drive clutch tooth 65 to mesh with transmission tooth 75 . Transmission tooth 75 rotates to drive driving wheel 8 to rotate.

[0044] In this embodiment, the clamping mechanism 9 is arranged in the rotating sleeve mold 2. When the clamping mechanism 9 is started, it can drive the two groups of clamping seats 3 inside the rotating sleeve mold 2 to move toward each other, thereby clamping the blank 4 on the upper and lower sides, so as to facilitate the cutting and washing of the front end of the blank 4. A clutch tooth 65 is arranged on one side of the clamping seat 3 through a coupling. When the two groups of clamping seats 3 are away from each other, the clutch tooth 65 can be synchronously driven to move in height. At this time, the clutch tooth 65 will mesh with the inner meshing convex ring 62 and the transmission tooth 75. At this time, the clamping seat 3 does not clamp the blank 4, and the push wheel 8 performs preliminary contact clamping on the blank 4. When the toothed disc 61 is driven to rotate by the execution motor 5, the transmission effect will directly drive the push wheel 8 to rotate through the transmission tooth 75, thereby pushing the blank 4 to move to one side and realizing feeding.

[0045] When the clamping seat 3 clamps the blank 4, the clutch tooth 65 will be separated from the transmission tooth 75 and the internal cam 62. At this time, the rotation of the toothed disc 61 will not drive the driving wheel 8 to rotate, but will drive the clamping seat 3 and the rotating sleeve mold 2 to rotate as a whole, flipping the blank 4, thereby changing the processing position of the blank 4 and improving flexibility.

[0046] refer to Figure 3 , Figure 5 and Figure 6 The separation transmission mechanism 6 includes a toothed disc 61 and a clutch tooth 65. The toothed disc 61 is fixed to the output shaft of the actuator motor 5 through a gear. The actuator motor 5 is fixed to the base 1. The toothed disc 61 is rotatably mounted in the base 1 through a limit seat.

[0047] In this embodiment, the toothed disc 61 is movably mounted on one side of the base 1 close to the rotating sleeve mold 2. After being driven by the motor 5, the toothed disc 61 can rotate through gear meshing, thereby achieving the purpose of transmission.

[0048] Reference Image Figure 3 , Figure 5 and Figure 6 The clamping seat 3 is also fixedly connected to a side surface near the clutch tooth 65 with two groups of oppositely distributed meshing blocks 64. The outer clamping convex ring 63 and the meshing block 64 are located in the same vertical plane direction, and the meshing block 64 is butted and engaged with the surface of the outer clamping convex ring 63. The transmission teeth 75 and the inner meshing convex ring 62 are located at the same horizontal height. The clutch teeth 65 can mesh with the inner meshing convex ring 62 and the transmission teeth 75 at the same time. The vertical positions of the transmission teeth 75 and the outer clamping convex ring 63 are staggered.

[0049] In this embodiment, the meshing block 64 is fixed on one side of the clamping seat 3, and the outer clamping convex ring 63 is fixed on one side of the toothed disc 61, and the meshing block 64 and the outer clamping convex ring 63 are located in the same vertical plane direction, so that when the clamping seat 3 moves downward, it will not only drive the clutch teeth 65 and the transmission teeth 75 and the inner meshing convex ring 62 to separate, but also realize the bite and docking between the meshing block 64 and the outer clamping convex ring 63. At this time, the rotation of the toothed disc 61 will directly drive the clamping seat 3 to rotate, and then drive the blank 4 to rotate;

[0050] The vertical positions of the transmission tooth 75 and the outer retaining convex ring 63 are staggered, indicating that the clutch tooth 65 and the outer retaining convex ring 63 are not in the same vertical plane. In this way, the clutch tooth 65 will not contact the outer retaining convex ring 63 during the movement of the clamping seat 3.

[0051] refer to Figure 3 and Figure 4 The pushing mechanism 7 includes a turbine rod 71 and a volute 72. The turbine rod 71 and the volute 72 are meshed for transmission. The turbine rod 71 is movably mounted in the rotating sleeve mold 2 through a side plate. The left and right sides of the volute 72 are respectively fixedly connected with side teeth 73 through connecting rods. The rotating sleeve mold 2 is provided with a side plate near the side teeth 73, and the side plate is provided with driving teeth 74 near the left and right sides of the side teeth 73. The driving teeth 74 mesh with the side teeth 73. The pushing wheel 8 is fixedly arranged on the opposite sides of the two groups of driving teeth 74 through a connecting shaft.

[0052] In this embodiment, when the transmission tooth 75 is driven to rotate, the rotation effect will directly drive the vortex tooth 72 below to rotate through the turbine rod 71. At this time, the vortex tooth 72 will drive the side teeth 73 on both sides to rotate, and the two groups of driving teeth 74 are respectively engaged with the left and right sides of the side teeth 73. In this way, the two groups of driving teeth 74 rotate, directly driving the driving wheel 8 to rotate, pushing the blank 4 to move to one side, and realizing the feeding operation.

[0053] refer to Figure 2 and Figure 4 The clamping mechanism 9 includes an active motor 91 and a telescopic frame 94. The output end of the active motor 91 is fixedly connected with a double-ended threaded rod 92. The left and right sides of the double-ended threaded rod 92 are respectively threadedly connected with transmission blocks 93, and the threaded connection directions of the two groups of transmission blocks 93 are opposite to those of the double-ended threaded rod 92. The telescopic frame 94 is a four-sided movable frame. The two sides of the telescopic frame 94 are respectively movably connected with the two groups of transmission blocks 93 through shaft pins. The upper and lower sides of the telescopic frame 94 are movably connected with support pins 95 through shaft holes. The support pins 95 are fixed on the side of the clamping seat 3. The surface of the clamping seat 3 is slidably connected with the rotating sleeve mold 2 through a slide rod.

[0054] In this embodiment, the active motor 91 can directly drive the double-ended threaded rod 92 to rotate after being driven. The transmission blocks 93 threadedly connected on both sides of the double-ended threaded rod 92 have different thread transmission directions, so that after the double-ended threaded rod 92 rotates, the two groups of transmission blocks 93 will move in opposite directions, and the two sides of the telescopic frame 94 are movably connected to the transmission blocks 93 through axle pins. Driven by the transmission blocks 93, the telescopic frame 94 will deform, and its upper and lower sides will directly push the two groups of clamping seats 3 through the support pins 95, so that the two groups of clamping seats 3 move away from each other and change the position of the clamping seats 3. Conversely, the two groups of clamping seats 3 approach each other, and the blank 4 is clamped on the upper and lower sides. The clamping seat 3 slides with the rotating sleeve mold 2 through the sliding rod to realize the limit operation and stabilize the up and down movement effect of the clamping seat 3.

[0055] A method for using a fixture for drilling processing comprises the following steps:

[0056] S1. First, the active motor 91 drives the double-end threaded rod 92 to rotate. Due to the different threaded connection directions of the two sets of transmission blocks 93, the two sets of transmission blocks 93 are limited by the rotating sleeve 2 and approach each other on the surface of the double-end threaded rod 92, pushing the telescopic frame 94 to deform. The telescopic frame 94 pushes the two sets of clamping seats 3 away from each other inside the rotating sleeve 2 to provide a space for the blank 4 to pass through. Then, the blank 4 is passed through between the two sets of driving wheels 8, providing a basic stabilizing effect under the resistance of the driving wheels 8. At the same time, the clamping seat 3 can drive the clutch teeth 65 to engage with the driving teeth 75 and the inner meshing convex ring 62.

[0057] S2, at this time, the motor 5 is driven to rotate by directly meshing the toothed disc 61 through the gears, and one side of the toothed disc 61 drives the clutch tooth 65 to rotate through the inner meshing convex ring 62. Under the transmission effect, the transmission tooth 75 is driven to rotate by the clutch tooth 65, thereby realizing the rotation of the turbine rod 71. The lower part of the turbine rod 71 is meshed with the vortex tooth 72, so that the vortex tooth 72 can drive the side teeth 73 on both sides to rotate through the connecting rod, and the side teeth 73 are meshed with the two sets of driving teeth 74, so that the driving teeth 74 can directly drive the two driving wheels 8 to rotate in the same direction, pushing the blank 4 to move to one side;

[0058] S3, after the blank 4 moves to the specified position, the active motor 91 drives the two groups of clamping seats 3 to approach each other, until the surface of the clamping seats 3 clamps the blank 4. Since the two groups of clamping seats 3 are close to each other, the clutch teeth 65 and the transmission teeth 75 and the inner convex ring 62 can be disengaged, and the meshing block 64 on one side of the clamping seat 3 can be engaged with the outer convex ring 63 on one side of the toothed disc 61, and then the blank 4 can be normally cut and washed;

[0059] S4. After cleaning, start the execution motor 5 again to rotate the toothed disc 61. Since the outer clamping convex ring 63 and the meshing clamping block 64 are locked with each other, the rotation effect of the toothed disc 61 will directly drive the two sets of clamping seats 3 to rotate, and the rotating sleeve mold 2 will also rotate above the base 1, thereby changing the rotation angle of the blank 4 and providing a wider cleaning space.

[0060] Working principle: First, insert the blank 4 between the two opposing groups of pushing wheels 8, then the active motor 91 in the clamping mechanism 9 drives the double-ended threaded rod 92 to rotate, and the transmission blocks 93 on both sides of the double-ended threaded rod 92 approach each other, pushing the telescopic frame 94 to deform, and the upper and lower positions of the telescopic frame 94 are connected to the two groups of clamping seats 3 through support pins 95. At this time, the clamping seats 3 will move toward each other inside the rotating sleeve mold 2, driving the clutch teeth 65 and the transmission teeth 75 on one side and the internal meshing convex ring 62 in the separation transmission mechanism 6. Meshing, at this time, the execution motor 5 at the bottom of the base 1 is started, and the gear plate 61 is rotated through the gear meshing. The inner meshing convex ring 62 will drive the transmission tooth 75 to rotate through the clutch tooth 65. The transmission tooth 75 is fixed to one end of the turbine rod 71, so that the turbine rod 71 will drive the vortex tooth 72 to rotate on the side plate frame set in the rotating sleeve die 2. Since the side teeth 73 are respectively fixed on both sides of the vortex tooth 72, the two groups of driving teeth 74 are respectively meshed on both sides of the side teeth 73, so that the driving teeth 74 directly drive the driving wheel 8 to rotate, so as to realize the pushing and squeezing of the blank 4 for feeding operation;

[0061] After the feeding end has reached a distance, the active motor 91 drives the clamping seats 3 to approach each other again. At this time, the clutch tooth 65 will disengage from the internal meshing convex ring 62 and the transmission tooth 75, and the rotation of the toothed disc 61 can no longer drive the push wheel 8 to move until the two groups of clamping seats 3 clamp the blank 4. At this time, the meshing block 64 on one side of the clamping seat 3 will engage with the external clamping convex ring 63. The rotation effect of the toothed disc 61 at this time will directly drive the two groups of clamping seats 3 to rotate, and the clamping seat 3 is arranged in the rotating sleeve mold 2, so that the rotating sleeve mold 2 is subjected to force when rotating above the base 1, changing the angular position of the blank 4, thereby improving the flexibility of processing the blank 4.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.

8. A fixture device for drill bit processing according to claim 7, characterized in that: The telescopic frame (94) is a four-sided movable frame, and two sides of the telescopic frame (94) are movably connected to two groups of transmission blocks (93) through shaft pins.

9. A fixture device for drill bit processing according to claim 8, characterized in that: The upper and lower sides of the telescopic frame (94) are movably connected to the support pin (95) through the shaft hole, and the support pin (95) is fixed to the side of the clamping seat (3). The surface of the clamping seat (3) is slidably connected to the rotating sleeve mold (2) through a sliding rod.

10. A method for using a fixture for drilling, characterized in that: The following steps are involved: S1. First, the active motor (91) drives the double-ended threaded rod (92) to rotate. Due to the different threaded connection directions of the two groups of transmission blocks (93), the two groups of transmission blocks (93) are restricted by the rotating sleeve (2) and approach each other on the surface of the double-ended threaded rod (92), pushing the telescopic frame (94) to deform. The telescopic frame (94) pushes the two groups of clamping seats (3) away from each other inside the rotating sleeve (2), providing a space for the blank (4) to pass through. Subsequently, the blank (4) is passed through between the two groups of driving wheels (8), providing a basic stabilizing effect under the resistance of the driving wheels (8). At the same time, the clamping seat (3) can drive the clutch teeth (65) to engage with the driving teeth (75) and the inner meshing convex ring (62); S2, at this time, the motor (5) is driven to rotate by directly meshing the toothed disc (61) through the gears, and one side of the toothed disc (61) drives the clutch tooth (65) to rotate through the internal meshing convex ring (62). Under the transmission effect, the transmission tooth (75) is driven to rotate by the clutch tooth (65), thereby realizing the rotation of the turbine rod (71). The lower part of the turbine rod (71) is meshed with the vortex tooth (72), so that the vortex tooth (72) can drive the side teeth (73) on both sides to rotate through the connecting rod, and the side teeth (73) are meshed with the two sets of driving teeth (74), so that the driving teeth (74) can directly drive the two driving wheels (8) to rotate in the same direction, pushing the blank (4) to move to one side; S3, after the blank (4) moves to the specified position, the active motor (91) drives the two groups of clamping seats (3) to approach each other, until the surface of the clamping seats (3) clamps the blank (4). As the two groups of clamping seats (3) approach each other, the clutch teeth (65) and the transmission teeth (75) and the inner meshing convex ring (62) can be driven to disengage, and at the same time, the meshing block (64) on one side of the clamping seat (3) can be engaged with the outer meshing convex ring (63) on one side of the toothed disc (61), and then the blank (4) can be normally cut and cleaned; S4. After the cleaning, the execution motor (5) is started again to rotate the toothed disc (61). Since the outer clamping convex ring (63) and the meshing clamping block (64) are locked with each other, the rotation effect of the toothed disc (61) will directly drive the two sets of clamping seats (3) to rotate, and the rotating sleeve die (2) will also rotate above the base (1), thereby changing the rotation angle of the blank (4) and providing a wider cleaning space.
