Description

Technical Field

[0001] The invention relates to the field of piston processing, and more specifically to a drilling mud pump piston processing device. Background Art

[0002] The piston mud pump is a common type of mud pump. Its working principle is to change the volume through the reciprocating motion of the piston in the cavity, thereby realizing the suction and discharge of liquid. The piston is a key component of the mud pump. In the processing and production of the piston, turning is an important link in the piston production process. This process is mainly completed using high-precision machine tools.

[0003] Since some cutting tools generate continuous spiral chips when cutting the workpiece during the turning process of the outer surface of the piston on the lathe, the chips generated by the cutting may be entangled with the tool or the outside of the workpiece. In the prior art, some lathe cutting tools are provided with chip breaker grooves to solve the chip problem. Although the chip breaking function can be realized, the chip breaker grooves will wear out over a long period of use, resulting in blunting of the tool edge, reduced cutting force, irregular formation and breaking of chips, and the effect of the cutting grooves will be greatly reduced. After the tool is excessively worn, the chips may not be separated and broken smoothly. At the same time, the prior art (Chinese invention patent with announcement number CN109079169B) discloses a high-pressure chip breaking device for a lathe for processing a wheel rim. The chips generated by the blade when turning are decomposed into smaller chips under the high-pressure spraying action of the high-pressure coolant. The blade will not produce the phenomenon of chip entanglement when in working state, and the chip breaking is realized by liquid cutting.

[0004] Although the liquid chip breaking method can achieve a certain chip breaking effect, the chips may become fragments or curl when the coolant impacts the chips, and it cannot guarantee that all chips can be effectively broken. In some cases (such as hard and long chips), the coolant may only bend them but not completely break them, causing the chips to still hang on the tool, resulting in tool wear or affecting the processing quality.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The present solution is provided with a chip breaking unit, which achieves chip breaking by pulling the chips entering the cover body to move them, thereby preventing the chips from adhering to the tool or workpiece for a long time, reducing tool wear and improving processing efficiency. The physical chip breaking method can more directly control the shape of the chips, and the chip breaking process is achieved through a simple mechanical mechanism, making the chip breaking cost lower.

When inclined lift block 1 and inclined lift block 2 are separated, the blade roller can be vertically lowered under the action of the reset part. The vertical movement can help the blade on the blade roller to act on the chips more directly during the cutting process, making them easier to break or disperse, thereby improving the cutting efficiency.

[0038] See also Figures 1 to 12 A drilling mud pump piston processing device includes a lathe 1, a tool feed part 2 connected to the lathe 1, and a tool fixture 3 installed on one side of the tool feed part 2.

[0039] A chip breaking unit 4 is connected to one side of the tool fixture 3, and the chip breaking unit 4 includes a fixed plate 41 fixedly connected to one side of the tool fixture 3, a cover body 42 fixedly connected to one side of the fixed plate 41, a chip storage chamber 421 opened inside the cover body 42 and a plurality of slide grooves 422 connected to the chip storage chamber 421, a horizontal moving unit 43 connected to one side of the cover body 42, a lifting control unit 44 connected to one side of the moving end of the horizontal moving unit 43, a plurality of insertion parts 46 fixedly connected to one side of the moving end of the lifting control unit 44, and a cutting and chip breaking part 5 connected to the inside of the chip storage chamber 421, and the plurality of insertion parts 46 all penetrate the moving end of the horizontal moving unit 43 and then respectively pass through the plurality of slide grooves 422 and extend into the chip storage chamber 421;

[0040] The cutting and chip breaking part 5 includes a plurality of rotating rods 57 rotatably connected to the chip storage chamber 421 , a plurality of blade rollers 56 respectively sleeved on the outside of the plurality of rotating rods 57 , and a driving assembly connected to the inside of the cover body 42 and used for driving the plurality of rotating rods 57 to rotate.

[0041] The horizontal moving unit 43 includes a screw rod 432 whose two ends are rotatably connected to the cover body 42 and the fixed plate 41 respectively, a guide rod 433 whose two ends are fixed to the cover body 42 and the fixed plate 41 respectively, a motor 431 fixed to one side of the fixed plate 41, a slide seat 434 slidably connected to one side of the cover body 42 and screwed to the outside of the screw rod 432, and the slide seat 434 is also movably sleeved on the outside of the guide rod 433, and the output shaft of the motor 431 passes through the fixed plate 41 and is fixed to one end of the screw rod 432.

[0042] The lifting control unit 44 includes a bracket 441 fixedly connected to one side of the slide 434, a screw rod 443 with two ends rotatably connected to the inner wall of the bracket 441 and one side of the slide 434 respectively, a lifting seat 45 slidably connected to the inner wall of the bracket 441 and screwed to the outside of the screw rod 443, a motor 442 fixedly connected to one side of the bracket 441, and the output shaft of the motor 442 passes through the bracket 441 and is fixedly connected to one end of the screw rod 443, the insertion part 46 is fixedly connected to the lower end of the lifting seat 45, and the other end of the insertion part 46 passes through the slide 434 and passes through the slide groove 422 to extend into the chip storage cavity 421.

[0043] By adopting the above technical solution, after the tool is clamped by the tool fixture 3, the fixing plate 41 is fixed to one side of the tool fixture 3 by bolts, and the cover body 42 is located at the upper end of the tool. The tool feed part 2 is controlled to drive the tool fixture 3 and the tool to move, so that the tool contacts the outer surface of the blank clamped on the lathe 1, and the outer surface of the piston blank is turned by the tool. The lathe 1 drives the fixture to rotate and drives the piston blank to rotate toward the direction of the tool. The chips are discharged outward from the upper end of the tool and enter the chip storage chamber 421 in the cover body 42. When the chips enter the chip storage chamber 42 1, the motor 2 442 works to drive the screw 2 443 to rotate, driving the lifting seat 45 to move in the direction of the slide 434, the lifting seat 45 descends and drives the insertion part 46 to descend, one end of the insertion part 46 passes through the slide 434 and the slide groove 422 and is inserted into the chips in the chip storage chamber 421, and then the motor 1 431 works to drive the screw 1 432 to rotate, the screw 1 432 rotates and drives the slide 434 to move, the slide 434 moves and drives the insertion part 46 to translate in the slide groove 422 toward the fixed plate 41, and the insertion part 46 drives the inside of the chip storage chamber 421 The chips move toward the chip storage chamber 421, so that the chips are disconnected from the workpiece to complete the chip breaking action, avoiding the chips from adhering to the tool or the workpiece for a long time, reducing tool wear and improving processing efficiency. The physical chip breaking method can more directly control the shape of the chips, and the chip breaking process is achieved through a simple mechanical mechanism, making the chip breaking cost lower. When the insert part 46 drives the chips to move inside the chip storage chamber 421, the disconnected chips will contact the blades on the blade roller 56 (the blade roller 56 is a column movably mounted on the outside of the rotating rod 57, and the outside of the column is The surface of the insert part 46 is fixed with multiple serrated blades), and the driving assembly drives the rotating rod 57 and the blade roller 56 to rotate, and cuts the chips moving in the chip storage chamber 421 to ensure that the chips are not excessively accumulated, and to prevent the chips from being knotted or entangled outside the insert part 46, so as to avoid affecting the next chip breaking action of the insert part 46. After the blade roller 56 cuts the chips, the motor 2 442 drives the lifting seat 45 to rise, so that the insert part 46 is pulled out of the chip storage chamber 421, and the motor 1 431 drives the slide 434 and the insert part 46 to translate and reset to wait for the next chip breaking action.

[0044] like Figure 4-Figure 6 As shown, a tooth key 1 423 is provided on the inner wall of the slide groove 422, and the insertion portion 46 includes a fixed rod 461 fixedly connected to the lower end of the lifting seat 45, a slot 463 provided at the other end of the fixed rod 461, a lever 462 whose one end is rotatably connected to the slot through a torsion spring, a tooth key 2 464 provided on the outer surface of one end of the lever 462, and a transmission component connected to the inside of the fixed rod 461 and respectively in transmission contact with the tooth key 1 423 and the tooth key 2 464 for driving the lever 462 to rotate.

[0045] The transmission assembly includes a gear 465 rotatably connected to both sides of a fixed rod 461 and meshing with a tooth key 423, a rod body 101 rotatably connected to the inside of the fixed rod 461 and connecting the two gears 465, two synchronous wheels 466 fixed to the outside of the rod body 101, a gear 467 rotatably connected to the inside of the fixed rod 461 and meshing with a tooth key 464, two synchronous wheels 468 fixed to both sides of the gear 467, and two synchronous belts 469 respectively connecting the two synchronous wheels 466 and the two synchronous wheels 468.

[0046] By adopting the above technical solution, when the slide 434 translates at the upper end of the cover body 42 and drives the insertion part 46 to translate, the gear 1 465 on both sides of the fixed rod 461 can contact the tooth key 1 423, and the tooth key 1 423 drives the gear 1 465 to rotate clockwise, and the gear 1 465 rotates clockwise to drive the synchronous wheel 1 466 to rotate clockwise, and the synchronous wheel 1 466 drives the synchronous wheel 2 468 to rotate clockwise through the synchronous belt 1 469, and the synchronous wheel 2 468 rotates clockwise and drives the lever 462 to rotate counterclockwise through the tooth key 2 464, and the lever 462 can rotate toward the direction of the fixed plate 41. At this time, the free end of the lever 462 can pick up the chips, so that the chips can be more smoothly combined with the blade roller 5 6 The upper blade contacts or moves up to the specified position. When the chips move up, the contact position and angle between the chips and the blade on the blade roller 56 can be changed, thereby improving the cutting efficiency of the blade on the chips, so that the blade can better cut most of the chips effectively, and at the same time can effectively avoid blockage. It should be noted here that when the gear 465 is separated from the tooth key 423, the lever 462 will rotate counterclockwise and return to a vertical state under the action of the torsion spring. When the lever 462 returns to a vertical state, the motor 442 drives the lifting seat 45 to rise, so that the insertion part 46 is pulled out of the chip storage chamber 421, and the motor 431 drives the slide 434 and the insertion part 46 to move horizontally and reset to wait for the next chip breaking action.

[0047] like Figure 7-10 As shown, the driving assembly includes a plurality of gear groups rotatably connected to the inside of the cover body 42 and consisting of two gear threes 55 as a group, a sprocket two 54 fixedly connected to one side of one of the gear threes 55 in the single gear group, a sprocket one 52 rotatably connected to the outside of one side of the cover body 42, a chain belt 53 drivingly connecting the sprocket one 52 with the plurality of sprocket twos 54, a motor three 51 fixedly connected to the outer surface of one side of the cover body 42 and with the output shaft fixedly connected to one side of the sprocket one 52, two adjacent rotating rods 57 form a group, one end of the plurality of rotating rods 57 are respectively fixedly connected to the other side of the plurality of gear threes 55, and the two gear threes 55 in the single gear group are meshed with each other.

[0048] The blade roller 56 is movably sleeved on the outside of the rotating rod 57, and a plurality of inclined top blocks 58 and a brush 59 are fixedly connected to the lower end of the blade roller 56. The inner wall of the chip storage chamber 421 is fixedly connected to a plurality of inclined top blocks 424 for pushing the inclined top block 58 to move vertically. A reset part 6 is also sleeved on the outside of the rotating rod 57.

[0049] The reset part 6 includes two sleeves 61 sleeved on the outside of the rotating rod 57, a plurality of balls 62 rotatably connected to one side of the two sleeves 61, and a spring 63 connecting the two sleeves 61 and sleeved on the outside of the rotating rod 57. The balls 62 of the two sleeves 61 are in contact with the blade roller 56 and the inner wall of the chip storage chamber 421 respectively.

[0050] By adopting the above technical solution, when the motor 3 51 works to drive the sprocket 1 52 to rotate, the sprocket 1 52 drives the other three sprocket 2 54 to rotate through the chain belt 53. When the sprocket 2 54 rotates, it can drive one of the gears 3 55 and the rotating rod 57 in the single gear group to rotate. The rotation of the gear 3 55 drives another gear 3 55 in the same gear group to rotate, so that the two adjacent rotating rods 57 and the blade rollers 56 outside the rotating rod 57 can respectively rotate clockwise and counterclockwise. The effect of this is that the two adjacent blade rollers 56 can not only cut off the chips, but also can move the rotating lever 462 The chips that are wrapped or sleeved on the outside are removed from the lever 462, so that the chips outside the lever 462 are quickly detached from the outside of the lever 462 and cut off. While the blade roller 56 rotates, the inclined top block 1 58 contacts the inclined top block 2 424. The inclined top block 2 424 can vertically lift the inclined top block 1 58 and the blade roller 56. When the inclined top block 1 58 and the inclined top block 2 424 are separated, the blade roller 56 can be vertically lowered under the action of the spring 63. The vertical movement can help the blades on the blade roller 56 to act on the chips more directly during the cutting process, making them easier to break or disperse, thereby improving the cutting efficiency.

[0051] like Figure 7 , Fig.11 and Fig.12 As shown, a plurality of nozzles 7 are rotatably connected to the inner wall of the cover body 42, and a pipe joint 8 is connected to the outer surface of one side of the cover body 42. An air supply pipeline 81 connecting the pipe joint 8 and the plurality of nozzles 7 is connected inside the cover body 42, and an adjustment component 10 for driving the nozzles 7 to rotate is also connected inside the cover body 42.

[0052] The adjusting assembly 10 includes a rod body 101 rotatably connected to the inside of the cover body 42, a plurality of synchronous wheels 3 102 fixedly connected to the outside of the rod body 101, a plurality of synchronous wheels 4 104 respectively fixedly connected to one side of the plurality of nozzles 7, and a plurality of synchronous belts 2 103 respectively connecting the plurality of synchronous wheels 3 102 with the plurality of synchronous wheels 4 104. A motor 4 9 is fixedly connected to the outer surface of one side of the cover body 42, and the output shaft of the motor 4 9 penetrates into the cover body 42 and is fixedly connected to one end of the rod body 101. Openings are also provided on both sides of the cover body 42, and a door panel 47 is clamped on the inner wall of the opening.

[0053] By adopting the above technical scheme, the pipe joint 8 is connected to the air pipe, and the gas in the air pipe enters the air pipe 81 from the pipe joint 8, and enters the nozzle 7 from the air pipe 81 and is discharged from the nozzle 7 to blow on the blade on the blade roller 56, thereby reducing the temperature of the blade and the temperature of the chips, avoiding the situation where the temperature of the chips and the blade is too high, causing thermal damage to the blade and affecting the service life of the blade. The motor 4 9 can drive the rod body 101 to rotate, and the rotation of the rod body 101 drives the synchronous wheel 3 102 to rotate. The rotation of the synchronous wheel 3 102 drives the synchronous wheel 4 104 and the nozzle 7 to rotate through the synchronous belt 2 103, and the angle of the nozzle 7 is adjusted so that the gas discharged from the nozzle 7 can be blown on different blades on the blade roller 56. Blowing air to the blade can effectively blow away the chips from the cutting area and the tool, prevent the chips from accumulating on the contact surface between the tool and the workpiece, and avoid tool blockage, chip re-entry into the processing area and reduced cutting efficiency caused by chip accumulation.

[0054] Method of use: remove the two door panels 47 from both sides of the cover body 42, connect the suction ends of the negative pressure suction device to the openings on both sides of the cover body 42 respectively, connect the pipe joint 8 to the air pipe, and the chips are discharged from the upper end of the tool to the outside and enter the chip storage chamber 421 in the cover body 42. The lathe 1 drives the workpiece to rotate, and the tool feed part 2 drives the tool fixture 3 and the cutting tool supported by the tool fixture 3 to move toward the front of the outer surface of the workpiece. The cutting tool contacts the outer surface of the workpiece to cut the outer surface of the workpiece. The initial contact stage between the cutting tool and the outer surface of the workpiece is the initial cutting stage (as the chip cutting time increases, the initial contact stage increases). The initial cutting stage becomes the later cutting stage. In the later cutting stage, the chips will become longer and longer, and the shape of the chips will change. Usually, they will be affected by their own gravity and other forces and gradually move downward or backward. This application mainly uses the chip breaking unit to continuously collect and cut the chips generated in the initial cutting stage, and is not aimed at collecting and processing the chips generated in the later cutting stage. When cutting just starts, the cutting force is mainly concentrated in the cutting area where the tool contacts the workpiece. Due to the action of the cutting force, the chips tend to form above the cutting area and move upward along the direction of the cutting force. This part of the force will push The moving chips move upward along the direction of the tool (i.e., the direction of movement of the tool), and the chips move upward and enter the chip storage chamber 421. When the chips enter the chip storage chamber 421, the lifting control unit 44 drives the insertion part 46 to descend, and one end of the insertion part 46 passes through the slide seat 434 and the slide groove 422 and is inserted into the chips in the chip storage chamber 421. Then the horizontal moving unit 43 drives the slide seat 434 to move, and the movement of the slide seat 434 drives the insertion part 46 to move horizontally in the slide groove 422 toward the fixed plate 41, and the insertion part 46 drives the chips inside the chip storage chamber 421 to move toward the inside of the chip storage chamber 421, thereby disconnecting the chips from the workpiece. After completing the chip breaking action, when the insertion part 46 drives the chips to move inside the chip storage chamber 421, the broken chips will contact the blades on the blade roller 56, and the driving assembly drives the rotating rod 57 and the blade roller 56 to rotate, so as to cut the chips moving in the chip storage chamber 421. The gas in the air pipe enters the gas pipeline 81 from the pipe joint 8, and enters the nozzle 7 from the gas pipeline 81 and is discharged from the nozzle 7 to blow on the blades on the blade roller 56, thereby reducing the temperature of the blades and the temperature of the chips, and also blowing the chips away from the cutting area and the tool. The cut chips can be sucked out by the negative pressure suction equipment and processed centrally.
