Description

Technical Field

[0001] This invention relates to the field of engine cylinder block loading technology, specifically a cylinder block loading tray and method compatible with multiple engine models. Background Technology

[0002] As a machine that can convert other forms of energy into mechanical energy, the engine body is the skeleton of the engine and the mounting base for the various mechanisms and systems of the engine. The engine body is mainly composed of parts such as cylinder block, cylinder liner, cylinder head and cylinder head gasket.

[0003] In automated production lines, automated conveying equipment is often used in conjunction with loading pallets, and mechanical grippers are used to remove and unload parts such as cylinder blocks and cylinder heads.

[0004] The cylinder block feeding tray mainly uses positioning columns and positioning pins for support and limitation, adapting to the positions of different cylinder block bottom bosses and reinforcing ribs to prevent the cylinder block from shaking during transportation and ensure feeding stability. However, in actual applications, because automated production lines produce cylinder blocks of different models, using a feeding tray with fixed positioning columns and positioning pins to support the cylinder block feeding results in long changeover times and high investment costs when multiple cylinder block production tasks are carried out on a single feeding and conveying line.

[0005] A fully automated engine block assembly line (patent document with publication number CN106938391A) is a fully automated production line consisting of a material rack, a manual feeding device, a pressing and marking device, a main shaft bolt feeding device, an automatic tightening device, a rework device, a lower cylinder block feeding device, an upper cylinder block feeding device, a discharge device, a robot arm for transporting the lower cylinder block from the lower cylinder block to the automatic tightening device, a second robot arm for transporting the workpiece from the manual feeding device to the pressing and marking device, and a third robot arm that work together to form a fully automated production line, which to some extent reflects the above-mentioned problems.

[0006] Therefore, how to provide a cylinder block loading tray and method compatible with multiple machine models is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] To overcome existing shortcomings, this application provides a cylinder block loading tray compatible with multiple machine models. A geared motor drives the drive gear to rotate, and a first rack meshing with it controls two push-pull strips to move closer or further apart. This, in turn, uses a driven gear meshing with a second rack to drive the assembly base column and assembly prism to rotate in opposite directions. This causes the first machine model component, which was originally at the top of the tray frame, to switch to a state where it is stored inside the tray frame, while the second machine model component, which was originally stored inside the tray frame, switches to a state where it is located at the top of the tray frame. This allows for simultaneous compatibility with the positioning of cylinder blocks from multiple machine models, significantly reducing the number of dedicated trays and shortening the tray changeover time.

[0008] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0009] A cylinder block loading pallet compatible with multiple machine models includes a pallet seat frame, a first machine model component, and a second machine model component, wherein the first machine model component is disposed on the top of the pallet seat frame;

[0010] The second model's components are housed inside the tray seat frame;

[0011] The pallet frame has an assembly prism and an assembly base column on its two sides. The assembly prism and the assembly base column are arranged along the long side of the pallet frame, and a switching structure is provided between their bottoms.

[0012] Both ends of the assembly prism and the assembly base column are machined with shafts, and two tile seats are opened at the top of both ends of the pallet seat frame. A pallet top plate is provided at the top of the pallet seat frame.

[0013] The four shafts are respectively connected inside the four bearing seats. The switching structure controls the assembly prism and assembly base column to rotate in opposite directions on the inside of the tray seat frame, thereby switching the first model component to be stored inside the tray seat frame, so that the second model component is located on the top of the tray seat frame.

[0014] In one possible implementation, the assembly prism includes a long prism rod and a short prism rod arranged coaxially, and the assembly base column includes a long cylindrical rod and a short cylindrical rod arranged coaxially.

A second rack is machined on the top surface of the push-pull bar, and a first rack is machined on the side of the push-pull bar. Driven gears are sleeved on the outside of the two connecting pins. The bottoms of the two driven gears are respectively engaged with the second racks on the two push-pull bars, and both sides of the drive gear are simultaneously engaged with the first racks on the two push-pull bars.

[0016] In one possible implementation, the push-pull bar has an F-shaped cross-section, and the top of the support base plate is machined with two limiting grooves parallel to the long side; the bottom of the push-pull bar is slidably connected to the inside of the limiting grooves, the bottom surface of the first rack is in contact with the top surface of the support base plate, and the two ends of the support base plate are respectively assembled to the inner walls of both sides of the tray seat frame.

[0017] In one possible implementation, the pallet top plate has a first movable slot and a third movable slot respectively opened inside both ends, a second movable slot is opened inside the center of the pallet top plate, and movable corner slots are opened inside the four corners of the pallet top plate; the two movable corner slots at one end of the pallet top plate are connected to the interior of the third movable slot, and the two movable corner slots at the other end of the pallet top plate are connected to the interior of the first movable slot.

[0018] In one possible implementation, the first model component includes two first positioning base posts and two second positioning base posts. The two second positioning base posts are respectively assembled into the interior of the opposite sides of the cylindrical short rod and the cylindrical long rod, and are both perpendicular to the axis of the mounting base post. The two second positioning base posts are arranged in the same direction. The two first positioning base posts are respectively assembled into the interior of the opposite sides of the prism long rod and the prism short rod, and are both perpendicular to the axis of the mounting prism. The two first positioning base posts are arranged in the same direction.

[0019] In one possible implementation, the second model component and the first model component are perpendicular to each other. The second model component includes two first limiting posts and two fourth limiting posts. An abutment plate is provided between each of the two first limiting posts and the two fourth limiting posts. A second limiting post and a third limiting post are provided on opposite sides of the two first limiting posts. The two first limiting posts are respectively assembled into the interior of the long prism rod and the short prism rod. The two fourth limiting posts are respectively assembled into the interior of the long cylindrical rod and the short cylindrical rod. The second limiting post and the third limiting post are respectively assembled into the interior of the opposite sides of the long prism rod and the short prism rod. The two abutment plates are respectively assembled into the interior of the long prism rod and the long cylindrical rod. The abutment plates on the two fourth limiting posts and the long cylindrical rod are arranged in the same direction. The abutment plates on the second limiting post, the third limiting post, the long prism rod, and the two first limiting posts are arranged in the same direction.

[0020] In one possible implementation, two storage corner slots are provided on the inner walls of both sides of the tray frame, the two abutting uprights and the two fourth limiting posts are located inside the two first limiting posts, the third limiting post and the second limiting post are located outside the two first limiting posts, and the two abutting uprights and the adjacent first and fourth limiting posts are staggered.

[0021] The two storage corner slots are located at both ends of the tray frame, the two first positioning bases and the two second positioning bases are movably connected to the inside of the four movable corner slots, the two first positioning bases and the two second positioning bases are respectively stored inside the four storage corner slots, the two abutment uprights are movably connected to the inside of the second movable slot, the third limiting post, the fourth limiting post and the first limiting post located at one end of the tray frame are movably connected to the inside of the first movable slot, and the second limiting post, the fourth limiting post and the first limiting post located at the other end of the tray frame are movably connected to the inside of the third movable slot.

[0022] In one possible implementation, first uprights are welded to the bottom of each of the four corners of the pallet top plate. A second upright is integrally formed at the bottom of each of the first uprights. A spring is sleeved onto the outside of each second upright, and a nut is threaded onto the bottom of each second upright. First cylindrical grooves are formed at the top of each of the four corners of the pallet frame, and second cylindrical grooves are formed at the bottom of each of the four corners of the pallet frame. The interiors of the four first cylindrical grooves and the four second cylindrical grooves are interconnected. The springs are supported between the bottom surface of the first uprights and the inner wall of the bottom of the first cylindrical grooves. The first uprights are slidably connected inside the first cylindrical grooves, and the second uprights are slidably connected inside the pallet frame. The nuts are movably connected inside the second cylindrical grooves.

[0023] A cylinder block feeding method compatible with multiple engine models includes the following steps:

[0024] Step 1: Determine the required positioning components based on the engine cylinder block it needs to support;

[0025] Step 2: With the bottom of the push-pull bar guided by the limiting groove, the drive gear is driven to rotate by the reduction motor. The first rack meshing with it controls the two push-pull bars to move closer or further apart. The driven gear meshing with the second rack drives the assembly base column and the assembly prism to rotate in opposite directions. The components of the first and second model components are perpendicular to each other, so that the first model component, which was originally at the top of the tray frame, is switched to a state where it is stored inside the tray frame, and the second model component, which was originally stored inside the tray frame, is switched to a state where it is located at the top of the tray frame.

[0026] Step 3: The robotic arm picks up the engine cylinder block and places it on the top of the pallet frame from top to bottom. The slots, bosses, and reinforcing ribs on the cylinder block are first guided by the first or second model assembly, and then pressure is applied to the top surface of the pallet top plate, which compresses the spring between the first column and the bottom inner wall of the first cylindrical groove. With the help of the first column sliding inside the first cylindrical groove and the second column sliding inside the pallet frame, the pallet top plate is guided to move vertically downward until the bottom surface of the pallet top plate is in contact with the top surface of the pallet frame, maintaining the position of the cylinder block by the first or second model assembly.

[0027] Step 4: The cylinder block is transported on the production line by the docking conveyor line and the robot.

[0028] The beneficial effects of this application are as follows:

[0029] Firstly, in this solution, the drive gear is driven to rotate by a geared motor, and the first rack meshing with it controls the two push-pull bars to move closer or further apart. This, in turn, uses the driven gear meshing with the second rack to drive the assembly base column and the assembly prism to rotate in opposite directions. This causes the first model component, which was originally on top of the pallet seat frame, to switch to a state where it is stored inside the pallet seat frame, while the second model component, which was originally stored inside the pallet seat frame, switches to a state where it is on top of the pallet seat frame. This solution can simultaneously accommodate the positioning of cylinder bodies of multiple models, significantly reducing the number of dedicated pallets and shortening the pallet changeover time.

[0030] Secondly, in this solution, by setting springs between the four corners of the pallet top plate and the pallet seat frame, when the engine cylinder block is placed on the top of the pallet seat frame from top to bottom, it is first guided by the first or second model component, and then pressure is applied to the top surface of the pallet top plate, so that the spring between the first column and the bottom inner wall of the first cylindrical groove is compressed. With the help of the first column sliding inside the first cylindrical groove and the second column sliding inside the pallet seat frame, when the bottom surface of the pallet top plate is in contact with the top surface of the pallet seat frame, the first or second model component positions the cylinder block, which can restrict its movement in the horizontal plane. During this process, it will not affect the rotation of the assembly prism inside the pallet seat frame, and ensure the length of the first or second model component when it extends from inside the pallet top plate to the top.

[0048] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0049] Example 1:

[0050] This embodiment describes the specific structure of a cylinder block loading tray compatible with multiple machine models, as detailed in the following reference. Figures 1 to 7 As shown, it includes a pallet frame 4, a first model component 1 disposed on the top of the pallet frame 4, and a second model component 9 housed inside the pallet frame 4. The pallet frame 4 has an assembly prism 8 and an assembly base column 2 respectively disposed on both sides inside. The assembly prism 8 includes a long prism rod 801 and a short prism rod 802 arranged coaxially. The assembly base column 2 includes a long cylindrical rod 201 and a short cylindrical rod 202 arranged coaxially. The long prism rod 801 and the long cylindrical rod 201 are both machined with a connecting pin 203 at the end away from the shaft 10.

[0051] The assembly prism 8 and the assembly base column 2 are arranged along the long side of the tray frame 4, and a switching structure 14 is provided between their bottoms. The switching structure 14 includes a support base plate 1401. A reduction motor 1403 is assembled and connected to the bottom of the support base plate 1401. One end of the shaft of the reduction motor 1403 passes through the support base plate 1401 and is assembled and connected to a drive gear 1404. Push-pull strips 1402 are provided on both sides of the drive gear 1404. A second rack 1407 is machined on the top surface of the push-pull strip 1402, and a first rack 1406 is machined on the side of the push-pull strip 1402.

[0052] The first model component 1 includes two first positioning base posts 101 and two second positioning base posts 102. The two second positioning base posts 102 are respectively assembled into the interior of the opposite parts of the cylindrical short rod 202 and the cylindrical long rod 201, and are both perpendicular to the axis of the mounting base post 2. The two first positioning base posts 101 are respectively assembled into the interior of the opposite parts of the prism long rod 801 and the prism short rod 802, and are both perpendicular to the axis of the mounting prism 8.

[0053] The second model component 9 is perpendicular to the first model component 1. The second model component 9 includes two first limiting posts 901 and two fourth limiting posts 905. An abutting plate 903 is provided between the two first limiting posts 901 and the two fourth limiting posts 905. A second limiting post 902 and a third limiting post 904 are provided on the opposite sides of the two first limiting posts 901. The two first limiting posts 901 are respectively installed inside the prism long rod 801 and the prism short rod 802. The two fourth limiting posts 905 are respectively installed inside the cylindrical long rod 201 and the cylindrical short rod 202. The second limiting posts 902 and the third limiting posts 904 are respectively installed inside the opposite sides of the prism long rod 801 and the prism short rod 802. The two abutting plates 903 are respectively installed inside the prism long rod 801 and the cylindrical long rod 201.

[0054] Both ends of the assembly prism 8 and the assembly base column 2 are machined with shafts 10, and two tile seats 13 are opened on the top of both ends of the pallet seat frame 4. The top of the pallet seat frame 4 is provided with a pallet top plate 3.

[0055] The connecting pin 203 on the cylindrical long rod 201 is pinned to the inside of the cylindrical short rod 202, and the connecting pin 203 on the prism long rod 801 is pinned to the inside of the prism short rod 802. Driven gears 1405 are sleeved on the outside of the two connecting pins 203, and the bottom of the two driven gears 1405 are respectively engaged with the second racks 1407 on the two push-pull bars 1402. The two sides of the driving gear 1404 are simultaneously engaged with the first racks 1406 on the two push-pull bars 1402. During the process of the reduction motor 1403 driving the driving gear 1404 to rotate, the first racks 1406 engaged with it control the two push-pull bars 1402 to move closer or further away from each other, thereby using the driven gears 1405 engaged with the second racks 1407 to drive the assembly base column 2 and the assembly prism 8 to rotate simultaneously.

[0056] When the switching structure 14 controls the assembly prism 8 and the assembly base column 2 to rotate in opposite directions inside the tray frame 4, the four shafts 10 are respectively connected to the inside of the four tile seats 13, so that the first model component 1, which was originally at the top of the tray frame 4, is switched to the state of being stored inside the tray frame 4, while the second model component 9, which was originally stored inside the tray frame 4, is switched to the state of being at the top of the tray frame 4.

[0057] Meanwhile, the two ends of the support base plate 1401 are respectively assembled to the inner walls of the two sides of the tray frame 4. By setting push-pull strips 1402 with an F-shaped cross section, and processing two limiting grooves 15 parallel to the long side on the top of the support base plate 1401, when the two push-pull strips 1402 are controlled to move closer or further away from each other, the driven gear 1405 meshing with the second rack 1407 drives the assembly base column 2 and the assembly prism 8 to rotate simultaneously, the bottom of the push-pull strip 1402 is slidably connected to the inside of the limiting groove 15, and the bottom surface of the first rack 1406 is in contact with the top surface of the support base plate 1401, which is conducive to guiding the push-pull strip 1402 to move along a fixed trajectory (while the stability of the rotation of the assembly prism 8 and the assembly base column 2 in the fixed plane, based on the weight of the assembly prism 8 and the assembly base column 2 themselves and their low-frequency rotation state, will not cause rotational wobbling due to the shaft 10 being inside the bearing seat 13 and the top of the bearing seat 13 being unobstructed).

[0058] It is worth noting that a bearing seat 13 with a top opening size smaller than the diameter can be used, or the bearing seat 13 can be set to a completely closed state (i.e., a hole). With the help of a shaft 10 that can be pinned to the inside of one end of the mounting base 2 or the mounting prism 8, the mounting base 2 and the mounting prism 8 can be rotated stably to switch the first model component 1 or the second model component 9 involved in the cylinder block positioning to work.

[0059] Secondly, when the first model component 1 is in the top position of the tray frame 4, the two first positioning base columns 101 and the two second positioning base columns 102 are all arranged in the same direction and vertically upward, which can support the engine cylinder block to be positioned on the top of the tray top plate 3.

[0060] When the second model component 9 is in the top position of the tray frame 4, the two fourth limiting posts 905 and the abutting plate 903 on the cylindrical long rod 201, the second limiting post 902, the third limiting post 904, the abutting plate 903 on the prism long rod 801 and the two first limiting posts 901 are arranged in the same direction and are vertically upward, which can support the engine cylinder block to be positioned on the top of the tray top plate 3;

[0061] In some examples, the inner sides of the pallet top plate 3 are respectively provided with a first movable slot 5 and a third movable slot 7, the inner side of the center of the pallet top plate 3 is provided with a second movable slot 6, the inner sides of the four corners of the pallet top plate 3 are provided with movable corner slots 11, and the inner walls of both sides of the pallet seat frame 4 are provided with two storage corner slots 12, which are located at the two ends of the pallet seat frame 4 respectively.

[0062] Specifically, by connecting the two movable corner slots 11 at one end of the pallet top plate 3 to the interior of the third movable slot 7, and connecting the two movable corner slots 11 at the other end of the pallet top plate 3 to the interior of the first movable slot 5, when switching the first model component 1 or the second model component 9 to the top of the pallet seat frame 4, the two first positioning bases 101 and the two second positioning bases 102 can be movably connected to the interior of the four movable corner slots 11, and the two first positioning bases 101 and the two second positioning bases 102 can be stored in the interior of the four storage corner slots 12 or withdrawn from the interior of the four storage corner slots 12.

[0063] Meanwhile, the two abutting uprights 903 are movably connected to the inside of the second movable slot 6. The third limiting post 904, the fourth limiting post 905 and the first limiting post 901 located at one end of the pallet frame 4 are movably connected to the inside of the first movable slot 5. The second limiting post 902, the fourth limiting post 905 and the first limiting post 901 located at the other end of the pallet frame 4 are movably connected to the inside of the third movable slot 7. This facilitates the laying of the pallet top plate 3 to the top of the pallet frame 4 to form a platform, supporting the engine cylinder block to be placed on the top of the pallet frame 4.

[0064] Secondly, to prevent interference between the components mounted on the mounting base 2 and mounting prism 8 when the second-model component 9 is stored inside the tray frame 4, and to ensure that the corresponding components do not affect the positioning of the subsequent engine cylinder block, such as... Figure 2 and Figure 4 As shown,

[0065] Two abutment plates 903 and two fourth limiting posts 905 are located inside the two first limiting posts 901, and the third limiting post 904 and the second limiting post 902 are located outside the two first limiting posts 901. The two abutment plates 903 and the adjacent first limiting posts 901 and fourth limiting posts 905 are all staggered. By staggering the two abutment plates 903 and the adjacent first limiting posts 901 and fourth limiting posts 905, the components assembled by the assembly base post 2 and the assembly prism 8 can be neatly stored inside the tray frame 4 while retaining the basic functions of the abutment plates 903, the first limiting posts 901 and the fourth limiting posts 905.

[0066] In this embodiment, the geared motor 1403 drives the drive gear 1404 to rotate, and the first rack 1406 meshing with it controls the two push-pull bars 1402 to move closer or further apart (the bottom of the push-pull bar 1402 slides inside the limiting groove 15). Thus, the driven gear 1405 meshing with the second rack 1407 drives the assembly base column 2 and the assembly prism 8 to rotate in opposite directions, so that the first model component 1, which was originally in the top position of the tray frame 4, is switched to the position of being stored inside the tray frame 4, while the second model component 9, which was originally stored inside the tray frame 4, is switched to the position of being in the top position of the tray frame 4.

[0067] During this process, the two first positioning base posts 101 and the two second positioning base posts 102 move inside the four movable corner slots 11 until they are stored inside the four storage corner slots 12. Meanwhile, the two abutting uprights 903 move inside the second movable slot 6. The third limiting post 904, the fourth limiting post 905 and the first limiting post 901 located at one end of the tray frame 4 move inside the first movable slot 5. The second limiting post 902, the fourth limiting post 905 and the first limiting post 901 located at the other end of the tray frame 4 move inside the third movable slot 7.

[0068] Example 2:

[0069] Based on Example 1, this example describes the specific structure between the pallet top plate 3 and the pallet seat frame 4, such as... Figure 2 , Figure 4 and Figure 8 As shown, the bottom of each of the four corners of the pallet top plate 3 is welded with a first column 16, the bottom of the first column 16 is integrally formed with a second column 18, the outside of the second column 18 is sleeved with a spring 21, and the bottom of the second column 18 is threaded with a nut 20.

[0070] The top of each of the four corners of the tray frame 4 is provided with a first columnar groove 17, and the bottom of each of the four corners of the tray frame 4 is provided with a second columnar groove 19.

[0071] The interiors of the four first cylindrical grooves 17 and the four second cylindrical grooves 19 are all connected. The spring 21 is supported between the bottom surface of the first column 16 and the bottom inner wall of the first cylindrical groove 17, so that the pallet top plate 3 is naturally separated from the pallet seat frame 4. This provides support for the rotation of the assembly prism 8, which has a larger diameter, and prevents the pallet top plate 3 from being fixed to the top of the pallet seat frame 4, which would affect the rotation of the assembly prism 8 and related components. It also shortens the length of the corresponding component when it extends from the inside of the pallet top plate 3 to the top.

[0072] Secondly, the first column 16 is slidably connected to the inside of the first columnar groove 17, the second column 18 is slidably connected to the inside of the pallet seat frame 4, and the nut 20 is movably connected to the inside of the second columnar groove 19. When the mechanical gripper picks up the engine cylinder block and places it on the top of the pallet seat frame 4 from top to bottom, the slots, bosses, and reinforcing ribs on the cylinder block are first guided by the first model assembly 1 or the second model assembly 9. When the cylinder block applies pressure to the top surface of the pallet top plate 3, and the spring 21 between the first column 16 and the bottom inner wall of the first columnar groove 17 is compressed, the first model assembly 1 or the second model assembly 9 positions the cylinder block and restricts its movement in the horizontal plane, making it easier for the pallet to carry and transfer the cylinder block.

[0073] In this embodiment, springs 21 are installed between the four corners of the pallet top plate 3 and the pallet seat frame 4, and are fitted onto the outside of the second column 18 at the bottom of the first column 16. When the engine cylinder block is placed on top of the pallet seat frame 4 from top to bottom, the slots, bosses, and reinforcing ribs on the cylinder block are first guided by the first model assembly 1 or the second model assembly 9, and then pressure is applied to the top surface of the pallet top plate 3, so that the springs 21 between the first column 16 and the bottom inner wall of the first cylindrical groove 17 are compressed. With the help of the first column 16 sliding inside the first cylindrical groove 17 and the second column 18 sliding inside the pallet seat frame 4, when the bottom surface of the pallet top plate 3 is in contact with the top surface of the pallet seat frame 4, the first model assembly 1 or the second model assembly 9 positions the cylinder block and restricts its movement in the horizontal plane. During this process, the rotation of the mounting prism 8 inside the pallet seat frame 4 will not be affected, and the length of the first model assembly 1 or the second model assembly 9 when it extends from inside the pallet top plate 3 to the top is guaranteed.

[0074] Specifically, when using this device to perform operations:

[0075] First, determine the required positioning components (first model component 1 or second model component 9) based on the engine cylinder block to be supported.

[0076] Then, with the bottom of the push-pull bar 1402 guided by the limiting groove 15, the drive gear 1404 is driven to rotate by the reduction motor 1403. The first rack 1406 meshing with it controls the two push-pull bars 1402 to move closer or further apart. Thus, the driven gear 1405 meshing with the second rack 1407 drives the assembly base 2 and the assembly prism 8 to rotate in opposite directions. The components of the first model assembly 1 and the second model assembly 9 are perpendicular to each other, so that the first model assembly 1, which was originally at the top of the tray frame 4, is switched to a state where it is stored inside the tray frame 4, and the second model assembly 9, which was originally stored inside the tray frame 4, is switched to a state where it is located at the top of the tray frame 4.

[0077] During this process, the two first positioning base posts 101 and the two second positioning base posts 102 move inside the four movable corner slots 11 until they are stored inside the four storage corner slots 12, while the two abutting uprights 903 move inside the second movable slot 6. The third limiting post 904, the fourth limiting post 905 and the first limiting post 901 located at one end of the tray frame 4 move inside the first movable slot 5, while the second limiting post 902, the fourth limiting post 905 and the first limiting post 901 located at the other end of the tray frame 4 move inside the third movable slot 7.

[0078] Next, the robotic arm picks up the engine cylinder block and places it on top of the tray frame 4 from top to bottom. The slots, bosses, and reinforcing ribs on the cylinder block are first guided by the first model component 1 or the second model component 9, and then pressure is applied to the top surface of the tray top plate 3, so that the spring 21 between the first column 16 and the bottom inner wall of the first cylindrical groove 17 is compressed. With the help of the first column 16 sliding inside the first cylindrical groove 17 and the second column 18 sliding inside the tray frame 4, the tray top plate 3 is guided to move vertically downward until the bottom surface of the tray top plate 3 is in contact with the top surface of the tray frame 4, maintaining the position of the cylinder block by the first model component 1 or the second model component 9.

[0079] Finally, the cylinder blocks are transported on the production line by a docking conveyor line and a robotic arm.

[0080] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
