Description

Technical Field

[0001] This application belongs to the technical field of drilling machines, and particularly relates to a special drilling machine for drilling inclined holes in a distribution sleeve and its control method. Background Art

[0002] Engines often work continuously for a long time. Therefore, it is necessary to ensure their working reliability and improve the power performance and economy of the engines. Since the working pressure of the fuel pump is high, it is a component that is prone to failure during the working process of the engine. At the same time, the fuel pump is also one of the key components affecting the overall working performance of the engine.

[0003] The existing Chinese patent with the publication number CN208858488U discloses a fuel pump head. A distribution sleeve is sleeved inside a distribution housing, and a distribution rotor is sleeved inside the distribution sleeve. Fuel enters the first oil inlet hole and the second oil inlet hole from the oil inlet, and the fuel entering the second oil inlet hole converges with the fuel filtered through the filter hole in the converging hole and then is input into the advance device connection hole for supplying oil to the advance device; part of the fuel entering the first oil inlet hole is input into the annular oil distribution groove through the first oil delivery inclined hole, and then is input into the central oil delivery hole through the second oil delivery hole and the third oil delivery hole. As described above, the distribution sleeve disclosed by the fuel pump head needs to be processed with oil delivery inclined holes.

[0004] The existing Chinese patents with the publication numbers CN110052874B and CN211053117U both disclose a drilling fixture. Although the above-mentioned drilling fixtures can all achieve the process of drilling inclined holes, the positioning methods used are not applicable to this distribution sleeve. The arc surface connected to one end of the oil delivery inclined hole is different from the outer wall surface of the distribution sleeve, and positioning needs to be carried out before drilling the oil delivery inclined hole. Summary of the Invention

[0005] The purpose of this application is to provide a special drilling machine for drilling inclined holes in a distribution sleeve and its control method to solve the above-mentioned existing technical problems, which can position the arc surface of the drilling surface of the distribution rotor workpiece and improve the drilling accuracy.

[0006] This application provides a special drilling machine for drilling inclined holes in a distribution sleeve, including:

[0007] A drilling machine body, on which a workbench is installed;

[0008] A clamping device, installed on the workbench, and the clamping device is provided with a base;

[0009] A limiting device, installed on the base;

[0010] A detection device, used to detect the arc surface of the workpiece to be drilled;

[0011] Among them, the clamping device includes an inclined seat, a clamping seat, a cylinder, and a motor. The clamping seat, the cylinder, and the motor are all installed on the inclined seat. The limiting device includes a limiting seat and a limiting sleeve. The limiting sleeve is installed on the limiting seat. The detection device is installed on the limiting seat.

[0012] After the workpiece is clamped by the clamping device, it is detected and positioned by the detection device. After positioning, the drill bit on the drill body drills the workpiece. The limiting device improves the stability of the drill bit during the machining of the drill body to ensure the drilling accuracy. When the workpiece is drilled, the base is placed on the workbench of the drill body. The inclined seat is installed on the base by bolts and nuts. The inclination angle of the inclined seat corresponds to the inclined hole on the workpiece. The clamping seat is installed on the inclined seat. The clamping seat adopts a collet chuck. The cylinder is used to control the clamping seat to clamp the workpiece. The motor can control the rotation of the clamping seat to adjust the clamped workpiece. The limiting seat is installed on the base by bolts and other fasteners. The limiting sleeve is installed on the limiting seat. The limiting sleeve is used to limit the drill bit of the drill body. When the detection device detects, the motor controls the rotation of the workpiece until the detection device detects a preset value and then stops.

[0013] Furthermore, the detection device includes:

[0014] A detection seat, installed on the limiting seat;

[0015] Detection balls, placed on the detection seat;

[0016] A cage, used to movably install the detection balls on the detection seat;

[0017] A first spring, with one side abutted against the cage;

[0018] A pressure sensor, installed on the detection seat and abutted against the other side of the first spring;

[0019] Among them, the cage is provided with a cover body. The cover body is threadedly connected to the cage and is adapted to the detection balls.

[0020] The detection seat is installed on the limiting seat. By installing the detection balls in the cage, the cage makes the installation structure of the detection balls stable through the cover body. The first spring is installed between the cage and the pressure sensor. When the detection device performs detection work, the detection balls are abutted against the outer wall surface of the workpiece. When the detection balls move to the arc surface to be machined, the cage moves, causing the detection value of the pressure sensor to change. By rotating the workpiece to the preset value of the pressure sensor, the positioning of the workpiece is achieved.

[0021] Furthermore, the limiting device further includes:

[0022] A cleaning brush, movably installed on the limiting seat;

[0023] The cleaning knife is installed on the limit seat, and the cleaning knife is used to clean the cleaning brush;

[0024] The first moving mechanism is used to control the movement of the cleaning brush and the detection device;

[0025] The second moving mechanism is used to control the movement of the limit sleeve;

[0026] The oil delivery system is installed on the limit seat and is connected to the limit sleeve;

[0027] Wherein, the limit sleeve is provided with an oil delivery hole.

[0028] After the workpiece is clamped on the clamping device, the surface of the workpiece is cleaned by the cleaning brush. By controlling the workpiece to rotate one circle, the debris on the surface of the workpiece is removed, ensuring the detection accuracy of the detection device for the workpiece. The cleaning knife is installed on the limit seat. The movement of the cleaning brush is controlled by the first moving mechanism. When the cleaning brush moves past the cleaning knife, the debris on the cleaning brush is cleaned, ensuring the cleaning effect of the cleaning brush on the surface of the workpiece. The movement of the cleaning brush and the detection device is controlled by the first moving mechanism. After the workpiece is clamped, the cleaning brush moves to contact the workpiece. By rotating the workpiece, the surface around the drilled hole of the workpiece is cleaned for one week, facilitating the subsequent detection by the detection device. After the cleaning brush finishes cleaning, the cleaning brush is reset by the first moving mechanism. During the movement, the cleaning of the cleaning brush is completed by the cleaning knife. While the first moving mechanism controls the reset of the cleaning brush, it also controls the detection device to extend, facilitating the subsequent detection and positioning of the workpiece. After the detection is completed, the detection device is further contracted by the first moving mechanism. Then, the second moving mechanism controls the limit sleeve to move towards the workpiece direction, further improving the stable effect of the limit sleeve on the drill bit by shortening the distance between the limit sleeve and the workpiece. The lubricating oil is transported through the oil delivery system. The lubricating oil is used for drilling, cleaning, and detection positioning. The oil delivery system transports the lubricating oil to the oil delivery hole, and the lubricating oil is evenly brushed on the surface around the drilled hole by the cleaning brush, facilitating the reduction of friction during subsequent detection and positioning.

[0029] Further, the first moving mechanism includes:

[0030] There are 2 moving parts, which are movably installed on the limit seat;

[0031] The connecting piece is connected to the moving part;

[0032] The connecting rod is connected to the connecting piece;

[0033] The pushing seat is movably connected to the connecting rod;

[0034] The first rack is installed on the limit seat;

[0035] The second rack is installed on the limit seat;

[0036] A gear is installed on the limit seat and placed between the first rack and the second rack, and the gear is engaged with both the first rack and the second rack;

[0037] A clutch mechanism is placed between the push seat and the first rack. The clutch mechanism is provided with a second spring, and the second spring acts on the first rack;

[0038] A sliding seat is placed on the limit seat, and the sliding seat is connected to the moving part away from the detection device;

[0039] A third spring acts on the sliding seat;

[0040] Wherein, the cleaning brush is connected to the moving part, the detection device is movably connected to the second rack, and the limit seat is provided with an arc-shaped chute corresponding to the sliding seat. The axis of the arc-shaped chute coincides with the hinge axis between the moving part without the sliding seat installed and the limit seat.

[0041] The moving part is installed between the limit seat and the cleaning brush. The two moving parts are parallel to each other. The connecting piece is hinged to the two moving parts. The push seat is driven to move by a cylinder, a hydraulic cylinder, etc. When the push seat moves, the connecting piece moves the moving part to control the movement of the cleaning brush. When the push seat moves to abut against the first rack, the push seat and the first rack are locked through the clutch mechanism. At this time, the push seat simultaneously pushes the sliding seat to move and controls the sliding seat to move downward along the arc-shaped chute, so that the cleaning brush is tilted, facilitating the lubricating oil dripping from the limit sleeve to be placed on the bristles of the cleaning brush, improving the brushing effect of the bristles on the lubricating oil. At the same time, the contact position between the tilted cleaning brush and the workpiece is convenient for some debris to fall off. When the push seat is reset, the sliding seat is reset by the third spring. At this time, when the cleaning brush is reset, it can ensure stable cooperation with the limit seat. When the push seat is reset, the push seat pulls the first rack to move. Through the transmission between the first rack, the gear, and the second rack, the detection device is controlled to extend, facilitating detection and positioning through the detection device. When the detection device completes the detection, the push seat and the first rack are separated through the clutch mechanism, and the first rack is reset by the second spring to retract the detection device, facilitating subsequent drilling processing.

[0042] Further, the second rack includes:

[0043] A push block is installed on the second rack;

[0044] A rotating block is installed on the detection device;

[0045] A top block is provided with a fourth spring and corresponds to the rotating block;

[0046] Wherein, the push block is provided with a push groove corresponding to the rotating block.

[0047] The pushing block is fixedly connected to the second rack, so as to realize the simultaneous movement of the pushing block with the second rack. When the pushing block moves and the rotating block is lifted by the top block and the fourth spring, the rotating block is pushed to rotate through the pushing groove. When the pushing block moves the rotating block towards the top block, the rotating block rotates to contract the detection device.

[0048] Furthermore, the clutch mechanism includes:

[0049] A clutch hook, installed on the pushing seat;

[0050] Electromagnets, respectively placed on the clutch hook and the pushing seat and corresponding to each other;

[0051] A fifth spring, acting on the clutch hook;

[0052] A clutch groove, placed on the first rack and corresponding to the clutch hook.

[0053] After the clutch hook and the clutch groove are engaged, the pushing seat and the first rack are locked by the action of the fifth spring on the clutch hook. When it is necessary to separate the pushing seat and the first rack, the clutch hook is controlled by the electromagnet to rotate, so as to realize the separation of the clutch hook and the clutch groove.

[0054] Furthermore, the second moving mechanism includes:

[0055] A movable plate, installed on the outer wall surface of the limiting sleeve;

[0056] A first cavity, placed on the limiting seat;

[0057] A first piston rod, installed on the movable plate and corresponding to the first cavity;

[0058] A second piston rod, placed in the first cavity;

[0059] A sixth spring, placed between the second piston rod and the first cavity;

[0060] A locking groove, placed on the second piston rod;

[0061] A locking hook, hinged on the limiting seat and corresponding to the locking groove, and the locking hook is provided with a seventh spring;

[0062] Wherein, a pressing part is arranged at the end of the locking hook, and an abutting part corresponding to the pressing part is arranged on the first rack.

[0063] The second moving mechanism is used to control the movement of the limit sleeve. The first cavity is filled with gas or liquid. When the second piston rod is pushed by the pushing seat, the second piston rod moves into the first cavity. The movement of the second piston is controlled by the air pressure in the first cavity. The second piston, the movable plate, and the limit sleeve move away from the workpiece. The pushing seat pushes the second piston rod and then locks the second piston rod through the cooperation of the locking hook and the locking groove. When the pushing seat is separated from the first rack through the clutch mechanism, the first rack is reset by the second spring, so that the abutting portion on the first rack contacts the pressing portion, thereby releasing the locked state between the locking hook and the locking groove. The seventh spring acts on the locking hook to reset the locking hook.

[0064] Furthermore, the oil delivery system includes:

[0065] An oil delivery channel, which is arranged in the limit seat;

[0066] An oil delivery groove, which is arranged on the outer wall surface of the limit sleeve and is connected between the oil delivery channel and the oil delivery hole.

[0067] The oil delivery channel is connected to lubricating oil. The movement of the limit sleeve ensures that the oil delivery groove corresponds to the oil delivery channel. The oil delivery groove is connected to the oil delivery hole, so that the inner wall surface of the limit sleeve keeps the lubricating oil flowing out and falls on the workpiece or the drill bit.

[0068] This application also provides a control method for a special machine for drilling inclined holes in a distribution sleeve. The specific steps include:

[0069] S1, clamping the workpiece to the clamping device;

[0070] S2, controlling the movement of the pushing seat, moving the cleaning brush to the workpiece, and driving the workpiece to rotate through the motor to clean the surface of the workpiece;

[0071] S3, controlling the pushing seat to move back to its original position, resetting the cleaning brush, pulling the first rack to move through the clutch mechanism, transmitting to the second rack to make the second rack move and extend the detection device, and driving the workpiece to rotate through the motor to position and drill the arc surface;

[0072] S4, after positioning, resetting the first rack through the clutch mechanism, and at the same time controlling the limit sleeve to move downward;

[0073] S5, drilling the workpiece through the drilling machine body.

[0074] After clamping the workpiece to the clamping device, first clean the debris on the surface of the workpiece around the drilling hole to ensure the detection accuracy of the detection device. At the same time, lubricating oil drops on the workpiece and the cleaning brush bristles. When the workpiece rotates one circle, lubricating oil is evenly applied to the workpiece to improve the lubrication performance between the detection device and the workpiece. After the detection device completes the detection and positioning of the workpiece, control the limit sleeve to move towards the workpiece, and drill the workpiece through the drilling machine body.

[0075] The beneficial effects of the present application are as follows:

[0076] 1. After the workpiece is clamped by the clamping device, it is detected and positioned by the detection device. After positioning, the drill bit on the drill body drills the workpiece, and the limiting device improves the stability of the drill bit during the processing of the drill body, ensuring the drilling accuracy.

[0077] 2. The detection ball abuts against the outer wall surface of the workpiece. When the detection ball moves to the arc surface to be processed, the cage moves, causing the detection value of the pressure sensor to change. After the workpiece is rotated to the preset value of the pressure sensor, the positioning of the workpiece is achieved.

[0078] 3. The surface of the workpiece is cleaned by the cleaning brush. By controlling the workpiece to rotate one circle, the debris on the surface of the workpiece is removed, ensuring the detection accuracy of the detection device for the workpiece. When the cleaning brush moves past the cleaning knife, the debris on the cleaning brush is cleaned, ensuring the cleaning effect of the cleaning brush on the surface of the workpiece.

[0079] 4. The movement of the cleaning brush is controlled by the first moving mechanism. The cleaning brush and the detection device are controlled to move by the first moving mechanism. Then, the limiting sleeve is controlled to move towards the workpiece by the second moving mechanism. By shortening the distance between the limiting sleeve and the workpiece, the stabilizing effect of the limiting sleeve on the drill bit is further improved. Lubricating oil is transported through the oil delivery system, and the lubricating oil is used for drilling, cleaning, and detection and positioning. BRIEF DESCRIPTION OF THE DRAWINGS

The detection device 400 is installed on the limiting seat 310.

[0102] After the workpiece is clamped by the clamping device 200, it is detected and positioned by the detection device 400. After positioning, the drill bit on the drill press body 100 drills the workpiece.

When the detection device 400 performs detection work, the detection balls 420 are in contact with the outer wall surface of the workpiece. When the detection balls 420 move to the arc surface to be processed, the cage 430 moves, causing the detection value of the pressure sensor 450 to change. After rotating the workpiece to the preset value of the pressure sensor 450, the positioning of the workpiece is achieved.

[0112] Embodiment 3:

[0113] As Figure 2 、 Figure 4 、 Figure 7 shown, the embodiment of the present application provides a special machine for drilling inclined holes in a distribution sleeve. In addition to including the above technical features, further, the limiting device 300 further includes:

The lubricating oil is transported through the oil delivery system 700. The lubricating oil is used for drilling, cleaning, and detection positioning. The oil delivery system 700 transports the lubricating oil to the oil delivery hole 710. The cleaning brush 330 evenly brushes the lubricating oil on the surface around the drilled hole, facilitating the reduction of friction during subsequent detection and positioning.

[0131] The sliding seat 590 is positioned on the limit seat 310. The sliding seat 590 is connected to the moving part 510 away from the detection device 400.

[0132] The third spring 591 acts on the sliding seat 590.

[0134] The moving part 510 is installed between the limit seat 310 and the cleaning brush 330. The two moving parts 510 are parallel to each other. The connecting part 520 is hinged to the two moving parts 510. The push seat 540 is driven to move through the air cylinder 240, hydraulic cylinder, etc. When the push seat 540 moves, the connecting part 520 moves the cleaning brush 330 to achieve control of its movement. When the push seat 540 moves to abut against the first rack 550, the push seat 540 and the first rack 550 are locked through the clutch mechanism 580. At this time, the push seat 540 simultaneously pushes the sliding seat 590 to move downward along the arc-shaped chute 592, so that the cleaning brush 330 is tilted, facilitating the lubricating oil dripping from the limit sleeve 320 to be placed on the bristles of the cleaning brush 330, improving the brushing effect of the bristles on the lubricating oil. At the same time, the contact position between the tilted cleaning brush 330 and the workpiece is convenient for some debris to fall off. When the push seat 540 resets, the sliding seat 590 resets through the third spring 591. At this time, when the cleaning brush 330 resets, it can ensure stable cooperation with the limit seat 310. When the push seat 540 resets, the push seat 540 pulls the first rack 550 to move. Through the transmission between the first rack 550, the gear 570, and the second rack 560, the detection device 400 is controlled to extend, facilitating detection and positioning through the detection device 400. When the detection device 400 completes the detection, the push seat 540 and the first rack 550 are separated through the clutch mechanism 580, and the first rack 550 is reset through the second spring 585 to retract the detection device 400, facilitating subsequent drilling processing.

[0135] Further, the second rack 560 includes:

[0136] The pushing block 561 is installed on the second rack 560;

[0137] The rotating block 562 is installed on the detecting device 400;

[0138] The top block 563 is provided with a fourth spring 564 and corresponds to the rotating block 562;

[0139] Wherein, the pushing block 561 is provided with a pushing groove 565 corresponding to the rotating block 562.

[0140] The pushing block 561 is fixedly connected to the second rack 560, so as to realize that the pushing block 561 moves simultaneously with the second rack 560. When the pushing block 561 moves to make the rotating block 562 be jacked up by the top block 563 and the fourth spring 564, the rotating block 562 is pushed to rotate through the pushing groove 565. When the pushing block 561 moves to move the rotating block 562 towards the top block 563, the rotating block 562 rotates to contract the detecting device 400.

[0141] Furthermore, the clutch mechanism 580 includes:

[0142] The clutch hook 581 is installed on the pushing seat 540;

[0143] The electromagnet 582 is respectively placed on the clutch hook 581 and the pushing seat 540 and corresponds to each other;

[0144] The fifth spring 583 acts on the clutch hook 581;

[0145] The clutch groove 584 is placed on the first rack 550 and corresponds to the clutch hook 581.

[0146] After the clutch hook 581 and the clutch groove 584 are matched, the pushing seat 540 and the first rack 550 are locked by the action of the fifth spring 583 on the clutch hook 581. When it is necessary to separate the pushing seat 540 and the first rack 550, the electromagnetic body 582 is controlled to drive the clutch hook 581 to rotate, so as to realize the separation of the clutch hook 581 and the clutch groove 584.

[0147] Embodiment 5:

[0148] As Figure 5 、 Figure 7 、 Figure 11 shown, the embodiment of the present application provides a special machine for drilling inclined holes in a distribution sleeve. In addition to including the above technical features, furthermore, the second moving mechanism 600 includes:

[0149] The movable plate 610 is installed on the outer wall surface of the limiting sleeve 320;

[0150] The first cavity 620 is placed on the limiting seat 310;

[0151] The first piston rod 630 is installed on the movable plate 610 and corresponds to the first cavity 620;

[0152] The second piston rod 640 is placed in the first cavity 620;

[0153] The sixth spring 650 is placed between the second piston rod 640 and the first cavity 620;

[0154] The locking groove 641 is placed on the second piston rod 640;

[0155] The locking hook 660 is hinged on the limit seat 310 and corresponds to the locking groove 641. The locking hook 660 is provided with a seventh spring 670;

[0156] Wherein, an end portion of the locking hook 660 is provided with a pressing portion 661, and the first rack 550 is provided with an abutting portion 551 corresponding to the pressing portion 661.

[0157] The second moving mechanism 600 is used to control the movement of the limit sleeve 320. The first cavity 620 is filled with gas or liquid. When the second piston rod 640 is pushed by the pushing seat 540, the second piston rod 640 moves into the first cavity 620. The movement of the second piston is controlled by the air pressure in the first cavity 620. The second piston, the movable plate 610, and the limit sleeve 320 move away from the workpiece. The pushing seat 540 pushes the second piston rod 640 and then locks the second piston rod 640 through the cooperation of the locking hook 660 and the locking groove 641. When the pushing seat 540 and the first rack 550 are separated by the clutch mechanism 580, the first rack 550 is reset by the second spring 585, so that the abutting portion 551 on the first rack 550 contacts the pressing portion 661, thereby releasing the locking state between the locking hook 660 and the locking groove 641, and the seventh spring 670 acts on the locking hook 660 to reset the locking hook 660.

[0158] Further, the oil delivery system 700 includes:

[0159] The oil delivery channel 730 is placed in the limit seat 310;

[0160] The oil delivery groove 720 is placed on the outer wall surface of the limit sleeve 320 and is connected between the oil delivery channel 730 and the oil delivery hole 710.

[0161] The oil delivery channel 730 is connected to lubricating oil. The movement of the limit sleeve 320 ensures that the oil delivery groove 720 corresponds to the oil delivery channel 730. The oil delivery groove 720 is connected to the oil delivery hole 710, so that the inner wall surface of the limit sleeve 320 maintains the outflow of lubricating oil and falls on the workpiece or the drill bit.

[0162] Embodiment 6:

[0163] The present application also provides a control method for a special machine for drilling inclined holes in a distribution sleeve, and the specific steps include:

[0167] S4, after positioning, resetting the first rack 550 through the clutch mechanism 580, and at the same time controlling the limiting sleeve 320 to move downward;

[0168] S5, performing drilling on the workpiece through the drilling machine body 100.

[0169] After clamping the workpiece onto the clamping device 200, first clean the debris on the surface of the workpiece around the drilling hole to ensure the detection accuracy of the detecting device 400. At the same time, lubricating oil is dripped onto the workpiece and the bristles of the cleaning brush 330. When the workpiece rotates one circle, lubricating oil is evenly applied to the workpiece to improve the lubrication performance between the detecting device 400 and the workpiece. After the detecting device 400 completes the detection and positioning of the workpiece, control the limiting sleeve 320 to move towards the workpiece, and perform drilling on the workpiece through the drilling machine body 100.
