Description

Technical Field

[0001] This invention relates to the field of diesel engine cylinder head processing technology, specifically to a processing device for medium- and high-speed marine diesel engine cylinder heads. Background Technology

[0002] The diesel engine is the heart of a ship, and the cylinder head is an important component of the diesel engine. Its performance can range from reducing the mechanical efficiency of the diesel engine to causing piston seizure, bearing seizure, or even destroying the entire diesel engine, resulting in irreparable damage.

[0003] In existing diesel engine cylinder head production lines, valve springs typically need to be installed, currently using two methods: fully automated equipment and manual installation. However, fully automated equipment often has limitations, either due to overly specialized instrumentation or high manufacturing and maintenance costs. Manual installation, on the other hand, generally uses spring assembly tools. These tools consist of a lever with a pressure block in the middle for pressing the valve spring. The pressure block has a circular hole for the spring's central axis to pass through. One end of the lever is fixed to the cylinder head, while the other end is held down with considerable force for valve spring installation. Because there are many springs, the lever needs frequent disassembly and reassembly during installation, resulting in low efficiency and high labor intensity. Furthermore, the direct contact between the spring and the valve guide hole during installation can easily damage the valve guide hole in the diesel engine cylinder head, failing to meet the needs of manual workers.

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Example 1 Please refer to Figures 1-16 As shown, a medium-to-high-speed marine diesel engine cylinder head processing device includes a base plate 1. A multi-functional robotic arm 101 is provided on the rear top side of the base plate 1. The multi-functional robotic arm 101 is used to transfer the cylinder head body A-1, valve stem A-2, chassis A-3, auxiliary spring A-4, main spring A-5, top plate A-6 and clamp A-7 on an external conveyor. A clamping and flipping mechanism 2 is installed in the middle of the top of the base plate 1. A first mounting mechanism 4 and a second mounting mechanism 5 are respectively provided on the rear and front sides of the clamping and flipping mechanism 2. An abutment mechanism 3 and a third mounting mechanism 6 are also installed on the clamping and flipping mechanism 2. The clamping and flipping mechanism 2, the abutment mechanism 3, the first mounting mechanism 4, the second mounting mechanism 5 and the third mounting mechanism 6 work together to automatically complete the installation of valve stem A-2, auxiliary spring A-4 and main spring A-5 on the cylinder head body A-1. Two sets of annular grooves are opened on the top of the chassis A-3, and a sealing rubber gasket is provided on the bottom of the chassis A-3.

[0020] Example 2 Please refer to Figure 2 and Figure 3 As shown, the clamping and flipping mechanism 2 includes two sets of support seats 201 welded to the top of the substrate 1. A first electric push rod 204 is rotatably connected inside the support seat 201. The output end of the first electric push rod 204 is fixedly connected to the frame 206. A first drive motor 202 is installed on the outside of the support seat 201. A first drive gear 203 is fixedly connected to the output end of the first drive motor 202. A first driven gear 205 that meshes with the first drive gear 203 is provided on the outer surface of the first electric push rod 204.

[0021] Please refer to Figure 3 As shown, the clamping and flipping mechanism 2 also includes a threaded rod 207 and a fixed rod 208. The threaded rod 207 is rotatably connected inside the frame 206, and the fixed rod 208 is fixedly connected inside the frame 206. Two sets of first clamping members 210 are slidably connected to the outer surface of the fixed rod 208. The threads at both ends of the threaded rod 207 have opposite directions of rotation, and the two sets of first clamping members 210 are respectively threaded to both ends of the outer surface of the threaded rod 207. A servo motor 209 for driving the threaded rod 207 to rotate is installed on the outside of the frame 206.

[0022] Those skilled in the art will understand that by controlling the extension or retraction of the output ends of the first electric push rods 204 on both sides, the frames 206 on both sides are brought closer or farther apart, thereby adapting the distance between the frames 206 on both sides to the length of the cylinder head body A-1; the output end of the servo motor 209 drives the threaded rod 207 to rotate, causing the two sets of first clamping members 210 to move closer or farther apart. When the two sets of first clamping members 210 are close together, they clamp the end of the cylinder head body A-1; when the two sets of first clamping members 210 are far apart, they clamp the end of the cylinder head body A-1. The cylinder head body A-1 is now released from clamping; and the output ends of the first drive motors 202 on both sides synchronously drive the first drive gears 203 on both sides to rotate, causing the first driven gears 205 and the first electric push rods 204 on both sides to rotate as a whole, thereby enabling the cylinder head body A-1, which is in a clamping state, to be flipped. Since the frame 206 in this invention has a certain weight, the frame 206 cannot always remain in a vertical state. The device is designed with the first drive motors 202 installed on both sides, which improves the rationality of the device design.

[0023] Example 3 Please refer to Figure 4 and Figure 5 As shown, the abutment mechanism 3 includes a first fixed frame 301, which is fixedly installed at the bottom of one of the frames 206. A first lead screw 302 is rotatably connected inside the first fixed frame 301. A movable block 305 is threadedly connected to the outer surface of the first lead screw 302. The movable block 305 is slidably connected to a first guide rod 303. The first guide rod 303 is welded inside the first fixed frame 301. A first stepper motor 304 is provided on the outer side of the first fixed frame 301. The output end of the first stepper motor 304 extends into the first fixed frame 301 and is fixedly connected to the outer end of the first lead screw 302. A second electric push rod 306 is provided on the outer side of the movable block 305. A first mounting block 307 is fixedly installed at the output end of the second electric push rod 306. A third electric push rod 308 is provided at the bottom of the first mounting block 307. An abutment block 309 is fixedly connected to the output end of the third electric push rod 308.

[0024] Those skilled in the art will understand that by driving the first lead screw 302 to rotate through the output end of the first stepper motor 304, the movable block 305 moves back and forth along the outer wall of the first guide rod 303, thereby driving the abutment block 309 to move back and forth. Furthermore, by controlling the extension or retraction of the output end of the second electric push rod 306, the first mounting block 307 moves left and right in the horizontal direction, thereby driving the abutment block 309 to move left and right. Since the guide hole positions for mounting valve stems A-2 are different for cylinder head bodies A-1 of different sizes, this setting allows the abutment block 309 to move freely to the corresponding position of the guide hole in both the horizontal and vertical directions. Moreover, by controlling the extension or retraction of the output end of the third electric push rod 308, the abutment block 309 moves up and down.

[0025] Example 4 Please refer to Figure 6 and Figure 7 As shown, the first mounting mechanism 4 includes a platform 401 disposed on the rear side of the top of the substrate 1. A second drive motor 402 is fixedly mounted on the bottom of the platform 401. A second mounting block 403 is disposed on the top of the substrate 1. The bottom middle of the second mounting block 403 is fixedly connected to the output end of the second drive motor 402. A double-headed electric cylinder 404 is disposed on the outer side of the second mounting block 403. A second clamping member 405 is fixedly mounted on both output ends of the double-headed electric cylinder 404.

[0026] Please refer to Figure 8 and Figure 9 As shown, the first mounting mechanism 4 also includes a second fixed frame 406 welded to the front side of the top of the platform 401. A second lead screw 407 is rotatably connected inside the second fixed frame 406. A second guide rod 408 is also fixedly installed inside the second fixed frame 406. A movable frame 410 is slidably connected to the outer wall of the second guide rod 408. The movable frame 410 is threaded to the outer wall of the second lead screw 407. A second stepper motor 409 that drives the second lead screw 407 to rotate is installed on the outside of the second fixed frame 406. A third lead screw 411 is rotatably connected inside the movable frame 410. The outer wall of the third lead screw 411 is threaded with a lifting block 414, which is slidably connected to the third guide rod 412. The third guide rod 412 is fixedly installed inside the movable frame 410. The top of the movable frame 410 is provided with a third stepper motor 413 that drives the third lead screw 411 to rotate. The outer side of the lifting block 414 is fixedly connected to the mounting frame 416 through a fourth electric push rod 415. A welding head 417 is rotatably connected inside the mounting frame 416, and a third drive motor 418 that drives the welding head 417 to rotate is provided on the outer wall of the mounting frame 416.

[0027] Those skilled in the art will understand that by controlling the synchronous extension or retraction of the two output ends of the double-headed electric cylinder 404, the two sets of second clamping members 405 are moved away from or closer to each other. When the two sets of second clamping members 405 are close to each other, the chassis A-3 is clamped on the top of the second mounting block 403. Conversely, when they are far apart, the clamping of the chassis A-3 is released. The output of the second stepper motor 409 drives the second lead screw 407 to rotate, causing the movable frame 410 to reciprocate left and right along the outer wall of the second guide rod 408, thus driving the welding head 417 to reciprocate horizontally. The output of the third stepper motor 413 drives the third lead screw 411 to rotate, causing the lifting block 414 to reciprocate up and down along the outer wall of the third guide rod 412, thus driving the welding head 417 to reciprocate up and down. By controlling the extension or retraction of the output of the fourth electric push rod 415, the welding head 417 is driven to reciprocate back and forth. In summary, the welding head 417 can reciprocate in three directions (horizontal, vertical, and horizontal) to reach the appropriate position for welding. The angle of the welding head 417 can be adjusted by the rotation of the output of the third drive motor 418, allowing the welding head 417 to accurately weld the welding point.

[0028] Example 5 Please refer to Figure 10 As shown, the second mounting mechanism 5 includes an L-shaped plate 505 and a pressing member 507. A third fixing frame 501 is fixedly connected to the front top of the base plate 1. A fourth lead screw 502 is rotatably connected inside the third fixing frame 501. The vertical plate of the L-shaped plate 505 is threadedly connected to the outer wall of the fourth lead screw 502. A fourth guide rod 503 is fixedly installed inside the third fixing frame 501. The vertical plate of the L-shaped plate 505 is slidably connected to the fourth guide rod 503. A fourth stepper motor 504 is installed on the outside of the third fixing frame 501. The outer end of the fourth lead screw 502 is fixedly connected to the output end of the fourth stepper motor 504. A fifth electric push rod 506 is fixedly connected to the top of the horizontal plate of the L-shaped plate 505. The top of the pressing member 507 is fixedly installed at the output end of the fifth electric push rod 506.

[0029] Those skilled in the art will understand that by driving the fourth lead screw 502 to rotate through the output end of the fourth stepper motor 504, the L-shaped plate 505 moves back and forth along the outer wall of the fourth guide rod 503, thereby driving the pressing component 507 to move back and forth; and by controlling the extension or retraction of the output end of the fifth electric push rod 506, the pressing component 507 is driven to move downward or upward.

[0030] Example 6 Please refer to Figure 11 and Figure 12As shown, the third mounting mechanism 6 includes a fourth fixed frame 601 fixedly mounted on the top of one of the support bases 201. A fifth lead screw 602 is rotatably connected inside the fourth fixed frame 601. A movable part 605 is threaded onto the fifth lead screw 602. The movable part 605 is slidably connected to a fifth guide rod 603. The fifth guide rod 603 is fixedly mounted inside the fourth fixed frame 601. The outer end of the fifth lead screw 602 is fixedly connected to the output end of a fifth stepper motor 604. The fifth stepper motor 604 is located on the outside of the fourth fixed frame 601. A sixth electric push rod 606 is mounted on the outside of the movable part 605. The output end of the sixth electric push rod 606 is fixedly connected to a third mounting block 607. A seventh electric push rod 608 is provided on the top of the third mounting block 607. The output end of the seventh electric push rod 608 penetrates the top wall of the third mounting block 607 and is fixedly mounted with a limit ring 609.

[0031] Please refer to Figure 13 As shown, a fourth drive motor 610 is provided at the bottom of the outer side plate of the limiting ring 609. A rotating rod 611 is fixedly installed at the output end of the fourth drive motor 610. The end of the rotating rod 611 away from the output end of the fourth drive motor 610 is welded to the top plate 612. An eighth electric push rod 613 is provided at the top of the top plate 612. A pressure block 614 is provided below the top plate 612. The top of the pressure block 614 is fixedly connected to the output end of the eighth electric push rod 613.

[0032] Please refer to Figure 12 and Figure 14 As shown, a second driven gear 617 is rotatably connected to the top of the limiting ring 609. A fifth drive motor 615 is also provided inside the outer plate of the limiting ring 609. A second drive gear 616 is installed at the output end of the fifth drive motor 615. The second drive gear 616 meshes with the second driven gear 617. A ninth electric push rod 618 is fixedly connected to the top of the second driven gear 617. A connector 619 is fixedly installed at the output end of the ninth electric push rod 618. A limiting member 620 is fixedly installed at the bottom of the connector 619.

[0033] Those skilled in the art will understand that by driving the fifth lead screw 602 to rotate through the output end of the fifth stepper motor 604, the movable part 605 moves back and forth along the outer wall of the fifth guide rod 603, thereby driving the limit ring 609 to move back and forth. Furthermore, by controlling the extension or retraction of the output end of the sixth electric push rod 606, the third mounting block 607 moves to the left or right, thereby driving the limit ring 609 to move horizontally back and forth. Moreover, by controlling the extension or retraction of the output end of the eighth electric push rod 613, the limit ring 609 is driven to move up and down. The output of the fourth drive motor 610 drives the rotating rod 611 to rotate, causing the top plate 612 to rotate around the center of the rotating rod 611, so that the pressure block 614 can rotate to be directly above the limiting ring 609. At this time, the center of the pressure block 614 and the center of the limiting ring 609 are on the same vertical line. Furthermore, by controlling the extension or retraction of the output of the eighth electric push rod 613, the pressure block 614 can be driven to move downward or upward. The output of the fifth drive motor 615 drives the second drive gear 616 to rotate, causing the second driven gear 617 to rotate around the outer wall of the limiting ring 609. This causes the ninth electric push rod 618 to rotate around the center of the second driven gear 617, which in turn causes the connecting piece 619 and the limiting piece 620 to rotate as a whole. By controlling the extension or retraction of the output of the ninth electric push rod 618, the connecting piece 619 and the limiting piece 620 can be moved upward or downward as a whole.

[0034] To clearly describe the working principle of this invention, we will use... Figure 1 This is an explanation from a directional perspective, referring to the "front, back, left, and right" perspectives mentioned below, as follows: S1. The cylinder head body A-1 on the external conveyor is transferred to the clamping and flipping mechanism 2 by the multi-functional robotic arm 101. The top of the cylinder head body A-1 is facing upward. By controlling the extension or retraction of the output ends of the first electric push rods 204 on both sides, the distance between the two side frames 206 is adapted to the length of the cylinder head body A-1. The left and right ends of the cylinder head body A-1 are between the two sets of first clamping members 210 on both sides. The output ends of the two servo motors 209 on both sides rotate synchronously, so that the two sets of first clamping members 210 connected to the same set of threaded rods 207 move closer to each other, thereby clamping and fixing the cylinder head body A-1. The output ends of the first drive motors 202 on both sides rotate synchronously, causing the cylinder head body A-1 in the clamping state to flip, so that the bottom of the cylinder head body A-1 is facing upward. At this time, the first fixing frame 301 also rotates to face upward. S2. The multi-functional robotic arm 101 transfers the valve stem A-2 from the external conveyor and inserts it upside down into the guide hole opened in the cylinder head body A-1. Then, with the cooperation of the output end of the first stepper motor 304 and the output end of the second electric push rod 306, the abutment block 309 moves freely in both horizontal and vertical directions to a position above the insertion position of the valve stem A-2. The output end of the third electric push rod 308 is controlled to extend, so that the abutment block 309 presses the bottom of the valve stem A-2. Then, the output ends of the first drive motors 202 on both sides are driven to rotate again, so that the cylinder head body A-1 flips again, with the bottom of the cylinder head body A-1 facing upwards. The valve stem A-2 will not fall off because its bottom is pressed by the abutment block 309. S3. The multi-functional robotic arm 101 transfers the chassis A-3 from the external conveyor and places it on top of the second mounting block 403. By controlling the synchronous retraction of the two output ends of the double-headed electric cylinder 404, the two sets of second clamping parts 405 are brought closer together to fix the chassis A-3. The multi-functional robotic arm 101 then transfers the auxiliary spring A-4 from the external conveyor and inserts its bottom into the annular groove on the inner side of the chassis A-3. The multi-functional robotic arm 101 continues to clamp the auxiliary spring A-4 and maintain its insertion posture to prevent the auxiliary spring A-4 from tilting. Then, through the coordinated use of the output ends of the second stepper motor 409, the third stepper motor 413, the fourth electric push rod 415, and the third drive motor 418, the... The welding head 417 accurately reaches the welding contact position and, in conjunction with the angle change, welds the bottom of the secondary spring A-4 to the chassis A-3. The annular groove is used to allow the welding head 417 to better locate the welding contact position between the secondary spring A-4 and the chassis A-3. The multi-functional robotic arm 101 then clamps and transports the main spring A-5 from the external conveyor to directly above the chassis A-3. The output of the second drive motor 402 drives the second mounting block 403 to rotate. This is done so that when the bottom of the main spring A-5 is subsequently inserted into another set of annular grooves in the chassis A-3, the bottom end point of the main spring A-5 and the bottom end point of the secondary spring A-4 are similarly located on the same radial direction of the chassis A-3 (e.g., ...). Figure 7 As shown), the bottom end point of the main spring A-5 and the bottom end point of the auxiliary spring A-4 are both located on the top front side of the chassis A-3. This is also to facilitate the welding head 417 to pass through the threads of the main spring A-5 and find the welding contact position better, so as to repeat the welding operation to achieve the connection between the main spring A-5 and the chassis A-3. S4. Using the multi-functional robotic arm 101, the welded auxiliary spring A-4, main spring A-5, and chassis A-3 are transported as a whole to the top of the guide hole in the cylinder head body A-1, and inserted downwards. The valve stem A-2 passes through the chassis A-3, auxiliary spring A-4, and main spring A-5. The sealing rubber gasket at the bottom of the chassis A-3 contacts the guide hole, preventing damage to the valve due to hard contact with the guide hole. Then, the multi-functional robotic arm 101 transports the external conveyor... The top plate A-6 is transferred to the top of the valve stem A-2 and pressed down to fit over the valve stem A-2. At this time, the auxiliary spring A-4 and the main spring A-5 remain in a contracted state. The multi-functional robotic arm 101 continues to clamp the top plate A-6. Then, with the cooperation of the output end of the fourth stepper motor 504 and the output end of the fifth electric push rod 506, the pressing part 507 presses onto the top plate A-6. The multi-functional robotic arm 101 releases the clamp, and the top plate A-6 remains in a horizontal state. S5. With the combined use of the output ends of the fifth stepper motor 604, the sixth electric push rod 606, and the eighth electric push rod 613, the limiting ring 609 moves accurately to the top plate A-6 and is positioned within the U-shaped groove of the pressure piece 507. Through the combined use of the output ends of the fifth drive motor 615 and the ninth electric push rod 618, the limiting piece 620 is positioned at the center of the limiting ring 609, with the bottom of the limiting piece 620 contacting the top of the valve stem A-2. The multi-functional robotic arm 101 clamps the clamping piece A-7 on the external conveyor and inserts it into the gap between the limiting piece 620 and the limiting ring 609. At this time, the outer wall of the limiting piece 620 is in contact with the inner semi-circular wall of the clamping piece A-7, and the inner wall of the limiting ring 609 is in contact with the outer semi-circular wall of the clamping piece A-7. The advantage of this arrangement is that card A-7 will not shift position during subsequent installation. However, the multi-functional robotic arm 101 is still holding card A-7 and not fully inserting it into the gap between the limiting member 620 and the limiting ring 609. Due to the interference of the crossbar of the connecting member 619, card A-7 is a semi-circular shape, which will affect the insertion of the next set of card A-7. Therefore, the output end of the fifth drive motor 615 drives the second drive gear 616 to rotate, so that the crossbar of the connecting member 619 is above the inserted card A-7. Then, the multi-functional robotic arm 101 fully inserts card A-7 into the gap. The multi-functional robotic arm 101 then transfers another set of card A-7 and inserts it into the other half of the gap, thus completing the insertion of two sets of card A-7. S6. Next, the limiting component 620 and the limiting ring 609 are reset as a whole. The output end of the fourth drive motor 610 drives the rotating rod 611 to rotate, causing the top plate 612 to rotate around the center of the rotating rod 611. This allows the pressure block 614 to rotate directly above the limiting ring 609. At this time, the center of the pressure block 614 and the center of the limiting ring 609 are on the same vertical line. The output end of the eighth electric push rod 613 extends, and the pressure block 614 moves downward and presses the two sets of clamps A-7. At the same time, the pressure component 507 also presses the top plate A-6 downward, thereby achieving the goal of holding the two sets of clamps A-7 tightly in the groove opened in the valve stem A-2. The outer wall of the clamp A-7 abuts against the inner wall of the top plate A-6, thus completing the automated installation of the valves on the cylinder head body A-1.
