Description

Technical Field

[0001] This invention relates to the field of cylinder head machining technology, and in particular to a cylinder head guide seat press-fitting machine. Background Technology

[0002] Motorcycle engine cylinder heads contain two guides: an intake guide and an exhaust guide. Seat rings are installed on the inner wall of the cylinder head at positions corresponding to these guides to improve their sealing. During production, the cylinder head is first formed using a mold, and then the guides and seat rings are installed after machining. Currently, the installation of guides and seat rings is primarily done manually. The seat ring is placed on a support post, the guide is fitted onto a press-fit head, and the cylinder head is aligned with the seat ring. Workers must control the cylinder head's position to prevent tilting and press down the press-fit head to force the guide into the cylinder head. Simultaneously, the seat ring is compressed and secured within the cylinder head. This installation method is difficult, labor-intensive, inefficient, and produces inconsistent quality. Furthermore, the installation process can damage the cylinder head, affecting product quality.

[0003] To address the aforementioned problems, this invention proposes a cylinder head guide seat press-fitting machine. Summary of the Invention

[0044] Example:

[0045] Reference Figures 1-14 As shown, a cylinder head guide seat ring pressing machine includes a frame 1, a workbench 2 in the middle of the frame 1, an mounting platform 3 at the top, a feeding mechanism 7 and a positioning mechanism 6 on the workbench 2, a transfer mechanism 8 and a pressing mechanism 9 on the mounting platform 3, and a guide tube cylinder 5 and a seat ring cylinder 4 on the frame 1.

[0046] The feeding mechanism 7 transports the guide tube and seat ring from the guide tube cylinder 5 and the seat ring cylinder 4 to the transfer mechanism 8;

[0047] The transfer mechanism 8 transports the conduit and seat ring to the pressing mechanism 9;

[0048] Positioning mechanism 6 clamps and fixes the cylinder head in the press-fit position;

[0049] Pressing mechanism 9 presses the guide tube and seat ring into the cylinder head respectively;

[0050] It also includes an electrical control device 10 and a control switch 11. The electrical control device 10 is electrically connected to the feeding mechanism 7, the positioning mechanism 6, the transfer mechanism 8 and the pressing mechanism 9 respectively through the control switch 11.

[0051] The cylinder head to be processed is clamped in the positioning mechanism 6. The guide tube is moved to the transfer mechanism 8 through the feeding mechanism 7. The transfer mechanism 8 then moves the guide tube to the pressing mechanism 9. The seat ring is moved to the rotating mechanism through the feeding mechanism 7. The transfer mechanism 8 then moves the seat ring to the pressing mechanism 9. The pressing mechanism 9 presses the guide tube and seat ring into the cylinder head, thus completing the installation of the guide tube and seat ring inside the cylinder head.

[0052] The positioning mechanism 6 includes a support plate 601 and a positioning plate 602. The top surface of the positioning plate 602 is provided with multiple positioning blocks 612 corresponding to the shape of the cylinder head, and the bottom surface is provided with two triangular adjusting plates 603 symmetrically. The bottom edge of the adjusting plate 603 is connected to the positioning plate 602. The support plate 601 is provided with a connecting block that is rotatably connected to the middle of the adjusting plate 603 near the adjusting plate 603. The support plate 601 is also hinged with an adjusting cylinder 604. The output end of the adjusting cylinder 604 is provided with an "L"-shaped hinge 605. One side wall of the hinge 605 is hinged to the adjusting cylinder 604, and the other side wall is connected to the positioning plate 602. Both the positioning plate 602 and the support plate 601 are provided with clearance holes 613.

[0053] The positioning block 612 is set on the positioning plate 602 to match the cylinder head spindle. The cylinder head is held on the positioning plate 602 by multiple positioning blocks 612. A triangular adjusting plate 603 is set on the bottom surface of the positioning plate 602. The middle part of the adjusting plate 603 is hinged to the connecting block on the support plate 601. When the adjusting plate 603 is rotated, its two sides can abut against the support plate 601 respectively, thereby adjusting the deflection angle of the positioning plate 602, thereby adjusting the angle of the cylinder head on the positioning plate 602. This ensures that the position of the guide tube and seat ring installed inside the cylinder head is in a vertical state, which facilitates the press-fitting assembly to press the guide tube and seat ring into the mounting hole on the cylinder head.

[0054] By adjusting the extension and retraction of the output shaft of cylinder 604, one end of hinge 605 is pulled, causing hinge 605 to rotate. One end of hinge 605 is fixed on positioning plate 602, which in turn drives positioning plate 602 to rotate. Cylinder head is held on positioning plate 602, thereby adjusting the deflection of cylinder head to select one of the two mounting holes on cylinder head to be in a vertical state for installation of guide tube and seat ring.

[0055] The clearance hole 613 on the positioning plate 602 facilitates the installation position of the seat ring against the cylinder head during press-fitting.

[0056] The feeding mechanism 7 includes a seat ring feeding assembly and a guide tube feeding assembly. The seat ring feeding assembly includes a seat ring cylinder 4 and a seat ring elevator 701 mounted on the seat ring cylinder 4. The output end of the seat ring elevator 701 is provided with a seat ring conveyor belt 703. The output end of the seat ring conveyor belt 703 is provided with a seat ring placement platform 70506. The side of the seat ring placement platform 70506 is provided with a seat ring reversing assembly 705. The conveyor belt is located on one side of the seat ring reversing assembly 705. The other side of the seat ring reversing assembly 705 is provided with a temporary locking post 70507. The top of the temporary locking post 70507 is provided with a positioning groove for positioning the seat ring. The guide tube feeding assembly includes a guide tube cylinder 5 and a guide tube elevator 702 mounted on the guide tube cylinder 5. The output end of the guide tube elevator 702 is provided with a guide tube conveyor belt 704. The output end of the guide tube conveyor belt 704 is provided with a guide tube positioning seat. The guide tube positioning seat is located on the other side of the guide tube conveyor belt 704, which is symmetrical to the guide tube conveyor belt 704, and the guide tube reversing assembly 706 is provided.

[0057] The seat ring with installation is placed in the seat ring cylinder 4. The seat ring is conveyed to the seat ring conveyor belt 703 by the seat ring elevator 701. The seat ring is moved to the seat ring placement platform 70506 by the seat ring conveyor belt 703. Then, the seat ring is placed in the positioning groove of the temporary clamping post 70507 according to the pressing requirements by the seat ring reversing assembly 705, so that the transfer mechanism 8 can clamp and convey the seat ring to the pressing mechanism 9. The guide tube is placed in the guide tube cylinder 5. The guide tube is conveyed to the guide tube conveyor belt 704 by the guide tube elevator 702. The guide tube positioning seat of the guide tube conveyor belt 704 facilitates the guide tube reversing operation by the guide tube reversing assembly 706.

[0058] The seat ring reversing assembly 705 includes two parallel connecting plates 70501, a rotating shaft 70503 rotatably disposed between the connecting plates 70501, a first reversing motor 70502 connected to one end of the rotating shaft 70503, a third gripper cylinder 70504 fixedly disposed on the rotating shaft 70503, and a second seat ring gripper 70505 disposed at the output end of the third gripper cylinder 70504.

[0059] The conduit reversing assembly 706 includes a fourth gripper cylinder 70607, which is located at the output end of the conduit conveyor belt 704 and fixed on the worktable 2. A second conduit gripper 81170608 is mounted on its output shaft. A support block 70609 is located on the side of the fourth gripper cylinder 70607 connected to the second conduit gripper 81170608, in the middle of the fourth gripper. The fourth gripper cylinder 70607 faces away from the conduit conveyor belt 704. A plug-in cylinder 70601 is provided on one side of 04. The output shaft of the plug-in cylinder 70601 is connected to a fixing block 70602 fixed on the worktable 2. A second reversing motor 70603 is provided on the plug-in cylinder 70601. A reversing rod 70604 is provided on the output shaft of the second reversing motor 70603. A connecting post 70605 is provided on the reversing rod 70604. One end of the connecting post 70605 is fixed on the reversing rod 70604, and the other end is provided with a plug-in rod 70606 that matches the inner diameter of the guide tube.

[0060] The third gripper cylinder 70504 drives the second seat ring gripper 70505 to work, which can clamp the seat ring and facilitate its movement. The first reversing motor 70502 drives the rotating shaft 70503 to rotate, and the third gripper cylinder 70504 is fixed on the rotating shaft 70503. When the rotating shaft 70503 rotates, the third gripper cylinder 70504 rotates together. However, when the second seat ring gripper 70505 clamps the seat ring, the rotating shaft 70503 rotates, which can flip the seat ring and move it from the seat ring placement platform 70506 to the positioning groove at the top of the temporary clamping post 70507. Since the seat ring lifting machine 701 lifts the seat ring, the installation direction of the seat ring is reversed. The seat ring reversing component 705 completes the reversal of the seat ring, which facilitates the transfer mechanism 8 to move the seat ring to the installation position. At the same time, the orientation of the seat ring meets the installation direction.

[0061] After the conduit is conveyed to the support block 70609 by the conveyor belt, it is clamped and fixed by the fourth gripper cylinder 70607. Then, the output shaft of the insertion cylinder 70601 extends, and at this time, the second reversing motor 70603 drives the reversing rod 70604 to rotate. The insertion rod 70606 on the reversing rod 70604 is in a horizontal state. As the output shaft of the insertion cylinder 70601 extends, the insertion rod 70606 moves towards the conduit and finally inserts the insertion rod 70606 into the conduit. Then, the fourth gripper cylinder 70607 releases the conduit, and the second reversing motor 70603 rotates, so that the insertion rod 70606 is in a vertical state. This makes the conduit sleeved on the insertion rod 70606 vertical, which is convenient for the transfer mechanism 8 to clamp the conduit for transfer.

[0062] The transfer mechanism 8 includes a first mounting plate 801, an X-axis moving assembly 802 on the first mounting plate 801, a second mounting plate 803 on the X-axis moving assembly 802, a Y-axis moving assembly 804 on the second mounting plate 803, a third mounting plate 805 on the Y-axis moving assembly 804, and a seat ring rotating assembly and a guide tube rotating assembly on the third mounting plate 805. The seat ring transfer assembly includes a first lifting cylinder 806609 and a second lifting cylinder 807609. The output end of the first lifting cylinder 806609 is provided with a first gripper cylinder 808, and the output end of the first gripper cylinder 808 is provided with a first seat ring gripper 809. The output end of the second lifting cylinder 807609 is provided with a second gripper cylinder 810, and the output end of the second gripper cylinder 810 is provided with a guide tube gripper 811.

[0063] The position of the third mounting plate 805 is adjusted by the X-axis moving assembly 802 and the Y-axis moving assembly 804, so that the position of the first seat ring clamping jaw 809 on the third mounting plate 805 corresponds to the position of the seat ring on the temporary clamping post 70507. At the same time, the first lifting cylinder 806609 drives the first clamping jaw cylinder 808 and the first seat ring clamping jaw 809 to move downwards. The first clamping jaw cylinder 808 drives the first seat ring clamping jaw 809 to clamp the seat ring. Then, the X-axis moving assembly 802 and the Y-axis moving assembly 804 align the position of the seat ring on the first seat ring clamping jaw 809 with the position of the pressing mechanism 9. Then, the first lifting cylinder 806609 places the seat ring on the pressing mechanism 9. The first clamping jaw cylinder 808 controls the first seat ring clamping jaw 809 to release the seat ring, and the seat ring stays on the pressing mechanism 9. The X-axis moving assembly 802 and the Y-axis moving assembly 804 are adjusted... The position of the third mounting plate 805 is such that the position of the guide clamp 811 on the third mounting plate 805 corresponds to the position of the guide on the insertion rod 70606. The second lifting cylinder 807609 moves the guide clamp 811 downward to the position of the guide. Then, the second clamp cylinder 810 drives the guide clamp 811 to retract, clamping the guide. Then, the second lifting cylinder 807609 drives the guide clamp 811 to rise, thereby removing the guide from the insertion rod 70606. Then, the position of the third mounting plate 805 is adjusted by the X-axis moving component 802 and the Y-axis moving component 804 so that the position of the guide corresponds to the position of the pressing mechanism 9. Then, the second lifting cylinder 807609 drives the guide to rise, so that the guide is fitted onto the pressing component. Then, the second clamp cylinder 810 controls the guide clamp 811 to release the guide, so that the guide stays on the pressing mechanism 9.

[0064] The pressing mechanism 9 includes an upper pressing assembly and a lower positioning assembly. The upper pressing assembly includes a pressing cylinder 901, which is fixed on the upper surface of the mounting platform 3. The output shaft of the pressing cylinder 901 is connected to a pressing head 902 that matches the inner diameter of the guide tube. The lower positioning assembly includes a positioning post 903. The diameter of the top end of the positioning post 903 is the same as the inner diameter of the mounting hole of the cylinder head to be processed, and the side wall of the top end of the positioning post 903 has an annular groove 90301 for locking the seat ring.

[0065] The annular groove 90301 at the top of the positioning post 903 is used to hold the seat ring, which facilitates the positioning of the seat ring. The first seat ring gripper 809 of the transfer mechanism 8 moves the seat ring from the temporary gripper 70507 to the positioning post 903, while the guide tube gripper 811 puts the guide tube onto the press head 902.

[0066] The cylinder head is positioned on the positioning plate 602. After the positioning pin 903 passes through the clearance hole 613 on the positioning plate 602, its end can penetrate into the mounting hole on the cylinder head, thereby causing the seat ring to abut against the mounting position inside the cylinder head.

[0067] It also includes a screening mechanism, which includes multiple industrial cameras and multiple screening cylinders. The industrial cameras are located on the lower surface of the mounting platform 3, and the multiple industrial cameras are respectively located above the seat ring conveyor belt 703 and the guide conveyor belt 704. The screening cylinders are located on the worktable 2, and the multiple screening cylinders are respectively located on one side of the seat ring conveyor belt 703 and the guide conveyor belt 704. The industrial cameras and screening cylinders are arranged sequentially along the conveying direction.

[0068] Multiple industrial cameras are used to detect whether the seat ring on the seat ring conveyor belt 703 is in the correct orientation and whether the two ends of the guide tube on the guide tube conveyor belt 704 are correctly positioned. If they are not, the seat ring is pushed off the seat ring conveyor belt 703 and falls into the seat ring material cylinder 4 by a screening cylinder, or the guide tube is pushed off the guide tube conveyor belt 704 and falls into the guide tube material cylinder 5 to ensure that the seat ring or guide tube is installed correctly.

[0069] The worktable 2 has two pressing positions, and corresponding machining holes are opened at the corresponding positions. A position adjustment mechanism is provided on the lower surface of the worktable 2 at the position corresponding to the machining hole. The position adjustment mechanism includes a fourth mounting plate 606, a positioning post 903 is provided on the upper surface of the fourth mounting plate 606, the fourth mounting plate 606 is fixed on the worktable 2 by a connecting rod, a slide rail 607 is provided on the fourth mounting plate 606, a support plate 601 is slidably mounted on the slide rail 607, a servo motor is also provided on the fourth mounting plate 606, the output shaft of the servo motor is connected to a lead screw, a slider 608 is threadedly connected to the lead screw, and the slider 608 is connected to the support plate 601; there are two sets of pressing mechanism 9, rotating mechanism and feeding mechanism 7, which correspond to the two pressing positions of the position adjustment mechanism respectively.

[0070] The servo motor drives the lead screw to rotate, which in turn causes the slider 608 to move along the lead screw. The support plate 601 is connected to the slider 608, which in turn causes the support plate 601 to move. This allows the support plate 601 to move between two pressing positions along the slide rail 607. The movement of the support plate 601 in turn causes the positioning plate 602 on the support plate 601 to move, thereby causing the cylinder head to move between the two pressing positions.

[0071] It also includes a lifting mechanism, which includes a lifting cylinder 609. The lifting cylinder 609 is fixedly mounted on the slider 608, and the output shaft of the lifting cylinder 609 is fixedly connected to the support plate 601. The lower surface of the support plate 601 is also provided with a guide rod 610 that penetrates the first mounting plate 801, and a spring 611 is sleeved on the guide rod 610. The spring 611 is located between the support plate 601 and the fourth mounting plate 606.

[0072] Since the fourth mounting plate 606 is fixed to the lower surface of the worktable 2 by the connecting rod, and one end of the lifting cylinder 609 is on the slider 608, and the slider 608 is set on the slide rail 607, the horizontal height of this end of the lifting cylinder 609 is fixed. The lifting cylinder 609 can drive the support plate 601 to move up and down, so that when the support plate 601 moves between the two pressing positions, when it reaches the position of the positioning post 903, it can raise the horizontal height of the cylinder head, so that the positioning post 903 can pass through the clearance hole 613 on the positioning plate 602 and the support plate 601 and abut against the pressing position inside the cylinder head, thereby ensuring that the seat ring locked at the top of the positioning post 903 can abut against the pressing position inside the cylinder head, ensuring normal processing, and avoiding the positioning post 903 interfering with the movement of the support plate 601 along the slide rail 607.

[0073] It also includes a safety light curtain 12 and a warning light 13. The safety light curtain 12 is located on one side of the workbench 2 where the positioning mechanism 6 is located, and the warning light 13 is located on the top of the frame 1. Both the safety light curtain 12 and the warning light 13 are electrically connected to the electronic control device 10.

[0074] The safety light curtain 12 can detect whether an object is passing through. The safety light curtain 12 is set on one side of the workbench 2 where the positioning mechanism 6 is located. The worker needs to clamp the cylinder head at this position, so this side is the worker's operating position. When the press machine is working, the safety light curtain 12 can detect in real time. If an object passes through the safety light curtain 12, it can be fed back to the control device in time. The control device can stop the equipment to prevent accidents and improve the safety of the workers. The warning light 13 can remind the workers near the equipment that the equipment is running and to pay attention to safety.

[0075] In use, the worker places the cylinder head onto the positioning plate 602 using the positioning block 612. The seat ring is then conveyed from the seat ring cylinder 4 to the seat ring conveyor belt 703 via the seat ring elevator 701. An industrial camera detects whether the front and back of the seat ring on the seat ring conveyor belt 703 meet the installation requirements. If they do, the seat ring is conveyed by the seat ring conveyor belt 703 to the seat ring placement table 70506. If they do not meet the installation requirements, a screening cylinder pushes the seat ring back into the seat ring cylinder 4. The first reversing cylinder drives the cylinder to rotate, and simultaneously, the third gripper cylinder 70504 on the rotating shaft 70503 drives the second seat ring gripper 70505 to clamp the seat ring on the seat ring placement table 70506. The first reversing cylinder then reverses the rotation. The rotation causes the seat ring to be engaged in the positioning groove at the top of the temporary clamping post 70507. The X-axis moving assembly 802 and the Y-axis moving assembly 804 then align the first seat ring gripper 809 with the seat ring. The first lifting cylinder 806609 moves the first seat ring gripper 809 to the position of the seat ring. The first gripper cylinder 808 then drives the first seat ring gripper 809 to clamp the seat ring. The X-axis moving assembly 802 and the Y-axis moving assembly 804 then align the position of the seat ring with the position of the positioning post 903, placing the seat ring in the annular groove 90301 at the top of the positioning post 903. The guide tube is then lifted from the guide tube cylinder 5 by the guide tube elevator 702. The guide tube is conveyed to the guide tube conveyor belt 704. An industrial camera detects whether the placement direction of both ends of the guide tube on the conveyor belt 704 meets the installation requirements. If it does not meet the requirements, a screening cylinder pushes the guide tube back into the guide tube cylinder 5. If it meets the requirements, the guide tube is conveyed to the guide tube positioning seat. The second reversing motor 70603 keeps the insertion rod 70606 horizontal. The fourth gripper cylinder 70607 drives the second guide tube gripper 81170608 to clamp the guide tube. Then, the insertion cylinder 70601 is activated, causing the insertion rod 70606 to insert into the guide tube. The second guide tube gripper 81170608 releases the guide tube, and the second reversing motor 70603 drives the insertion rod 70606... Rotating 06 causes the insertion rod 70606 to be in a vertical position, thereby making the conduit vertical. Then, the X-axis moving component 802 and the Y-axis moving component 804 align the position of the conduit gripper 811 with the position of the conduit on the insertion rod 70606. The second lifting cylinder 807609 moves the conduit gripper 811 to the position of the conduit. The second gripper cylinder 810 drives the conduit gripper 811 to clamp the conduit. Then, the X-axis moving component 802 and the Y-axis moving component 804 work together to align the position of the conduit with the position of the pressing head 902. The second lifting cylinder 807609 raises the conduit, thereby placing the conduit onto the pressing head 902.Then, the servo motor drives the lead screw to rotate, causing the slider 608 to move to the left, which in turn moves the support plate 601 to the left pressing position. At the same time, the lifting cylinder 609 drives the support plate 601 to move upward, so that the position of the positioning post 903 corresponds to the position of the clearance hole 613. Then, the lifting cylinder 609 drives the support plate 601 to descend, so that the top of the positioning post 903 abuts against the installation position inside the cylinder head. The X-axis moving component 802 and the Y-axis moving component 804 make the position of the pressing head 902 correspond to the installation position of the guide tube on the cylinder head. Then, the pressing cylinder 901 drives the pressing head 902 to press down, pressing the guide tube into the installation hole inside the cylinder head. At the same time, the cylinder head is pressed downward. The movement allows the seat ring to be pressed into the installation position inside the cylinder head, completing the installation of the seat ring and guide tube at one installation hole inside the cylinder head. Then, the lifting cylinder 609 drives the support plate 601 to rise, causing the support plate 601 to move away from the positioning post 903 at the left installation position. Then, the adjusting cylinder 604 drives the hinge 605 to rotate, which in turn drives the adjusting plate 603 to rotate on the connecting block, so that the other installation hole on the cylinder head is in a vertical state. At the same time, the seat ring is placed on the top of the positioning post 903 on the right side, and the guide tube is fitted onto the pressing head 902. Then, the servo motor drives the adjusting plate 603 to move to the positioning post 903 on the right side of the pressing position, and the pressing cylinder performs the pressing, completing the installation of the guide tube and seat ring at the air inlet and air outlet pipes on the cylinder head.

[0076] In practical use, the X-axis moving assembly 802 and the Y-axis moving assembly 804 adopt a high-precision ball screw servo moving platform for the X and Y axes to ensure that the pressing head 902, the positioning column 903 and the mounting holes on the cylinder head can be accurately aligned on the same axis.

[0077] A position sensor is installed on the lower surface of the mounting platform 3. The position sensor is on the same plane as the axis of the positioning column 903 and the axis of the mounting hole on the cylinder head. The position sensor senses whether the pressing head 902 has moved above the positioning column 903, which further improves the accuracy of the fit between the pressing head 902 and the positioning column 903 and further improves the product quality.

[0078] The control switch 11 is located on the side of the frame 1 where the worker operates, and is on the same side as the safety light curtain 12. The safety light curtain 12 can detect whether the worker accidentally passes through the safety light curtain 12 and enters the pressing area of ​​the pressing machine when operating the control switch 11, thereby improving the safety of the worker.

[0079] Throughout the installation process, workers only need to clamp the cylinder head onto the positioning plate 602, which greatly reduces the workload and labor intensity of workers and improves the pressing efficiency. The guide tube and seat ring are both completed through pressing, ensuring the quality of the product.
