In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0034] The present utility model discloses a cylinder liner O-ring assembly device. Refer to Figures 1 - 3As shown, the cylinder liner O-ring assembly equipment includes an O-ring storage device 100, an O-ring grasping device 200, a cylinder liner grasping device 300 and a detection device. The O-ring storage device 100 includes a rotary driving member 110, a storage support 120 and a plurality of storage columns 130. The storage support 120 is fitted with the rotary shaft of the rotary driving member 110. The plurality of storage columns 130 are arranged at intervals on the storage support 120 and are arranged around the rotary shaft of the rotary driving member 110. Each storage column 130 is provided with a plurality of O-rings. The O-ring grasping device 200 includes a transverse movement module 220 and an O-ring grasping module 210. The transverse movement module 220 is in driving cooperation with the O-ring grasping module 210, and the transverse movement module 220 is used to drive the O-ring grasping module 210 to move to take out the O-ring on the storage column 130. The cylinder liner grasping device 300 includes a robot and a cylinder liner grasping module 310. The cylinder liner grasping module 310 is detachably installed at the end of the robot. The cylinder liner grasping module 310 is used to grasp the cylinder liner, and the robot is used to drive the cylinder liner grasping module 310 to move to insert the cylinder liner into the O-ring. The detection device is arranged in parallel with the cylinder liner grasping device 300, and the cylinder liner grasping device 300 can transport the cylinder liner sleeved with the O-ring to the detection area of the detection device to realize the photographing detection of the cylinder liner sleeved with the O-ring. First of all, it should be noted that the control mechanism can be a centralized or distributed controller. For example, the controller can be a single separate single-chip microcomputer, or can be composed of multiple distributed single-chip microcomputers. A control program can run in the single-chip microcomputer. The control mechanism is electrically connected to the O-ring storage device 100, the O-ring grasping device 200, the cylinder liner grasping device 300 and the detection device to realize intelligent control. The specific type and control logic of the control mechanism are prior art, and the control mechanism will not be described in detail here.

[0035] It can be understood that during the actual working process, first, the end of the robot moves to the position corresponding to the cylinder liner grasping module 310 and cooperates with the appropriate cylinder liner grasping module 310 according to the size of the cylinder liner. Then, the rotation driving member 110 drives the storage column 130 with a specified size to rotate to a position parallel to the transverse movement direction of the transverse movement module 220. The transverse movement module 220 drives the O-ring grasping module 210 to the end of the storage column 130 to grasp a specified size O-ring, and the transverse movement module 220 drives the O-ring grasping module 210 to the assembly position. Then, the robot drives the cylinder liner grasping module 310 to grasp the cylinder liner with a specified size, and drives the cylinder liner through the O-ring. The O-ring grasping module 210 releases the O-ring to complete the assembly of the cylinder liner and the O-ring. Then, the robot drives the cylinder liner grasping module 310 to move the cylinder liner sleeved with the O-ring to the detection area of the detection device for photographing and detecting the cylinder liner sleeved with the O-ring. If the assembly is unqualified, the control mechanism sends a signal to prompt the operator. If the assembly is qualified, the control mechanism sends a signal to let the robot drive the cylinder liner grasping module 310 to place it into the cylinder block pressing device 500 for pressing. Thus, during the entire O-ring assembly process, there is no need for the operator to manually install, realizing the automatic installation of the O-ring onto the cylinder liner, improving the assembly efficiency of the O-ring, and because the detection device can perform photographing and detection, the anti-error function and data traceability function can be better realized during the assembly process.

[0036] It should be added that during the actual working process, the cylinder liner can be transported to the specified position by the cylinder liner transportation line and then grasped by the cylinder liner grasping device 300, or it can be transported by the manipulator from the previous station to the position corresponding to the cylinder liner grasping device 300. It can also be specifically provided with a cylinder liner storage device for storing the cylinder liner. During the actual working process, the cylinder liner grasping device 300 can grasp the cylinder liner on the cylinder liner storage device.

[0037] Optionally, a plurality of storage grooves 131 are provided on the storage column 130 at intervals along its axial direction, and the storage grooves 131 are used for storing O-rings. It can be understood that each O-ring installed in a storage groove 131 can prevent the O-ring from moving axially along the storage column 130 when the rotation driving member 110 drives the storage support 120 to rotate and drive the storage column 130 to rotate, thereby ensuring the stability of the O-ring on the storage column 130 and ensuring that the assembly process can proceed stably.

[0038] Further optionally, in order to facilitate the replenishment of O-rings on the storage column 130, the storage column 130 is formed as a pneumatic expansion shaft, that is, the storage column 130 has a contracted state and an expanded state. In the contracted state, the inner diameter of the O-ring is larger than the outer diameter of the storage column 130, and in the expanded state, the inner diameter of the O-ring is smaller than the outer diameter of the storage column 130 so that the O-ring is stretched. In the actual working process, when it is necessary to replenish O-rings on the storage column 130, the storage column 130 switches to the contracted state, and the operator can quickly replenish the O-rings. After replenishment, the storage column 130 switches to the expanded state to stretch the O-rings, and the O-ring grabbing device 200 takes out the stretched O-rings to ensure that the O-rings can be stably mounted on the outer wall of the cylinder sleeve. It should be supplemented here that the structure of the pneumatic expansion shaft is a prior art and does not need to be elaborated here.

[0039] refer to Figure 1 and Figure 2 As shown, the O-ring storage device 100 also includes a base 140 and a transmission shaft 150. The base 140 is used to support the rotating drive member 110. Both ends of the transmission shaft 150 are rotatably arranged on the base 140 and cooperate with the rotating shaft of the rotating drive member 110. There are multiple storage brackets 120, and the multiple storage brackets 120 are arranged on the transmission shaft 150 at intervals; there are multiple O-ring grabbing devices 200, and the multiple O-ring grabbing devices 200 are arranged in a one-to-one correspondence with the multiple storage brackets 120. It can be understood that the multiple storage brackets 120 can enable the O-ring storage device 100 to store more different types of O-rings, thereby realizing the assembly of O-rings of different sizes, and improving the compatibility and application range of the cylinder liner O-ring assembly equipment of this embodiment.

[0040] refer to Figure 4As shown, the O-ring grasping module 210 includes a first grasping bracket 211, a plurality of first grasping components 212, and a first detection component 213. The first grasping bracket 211 has a mating hole 2111 for passing through the cylinder liner and the storage column 130, and the first grasping bracket 211 is connected to the transverse movement module 220. A plurality of first grasping components 212 are arranged on the first grasping bracket 211 and are arranged around the mating hole 2111. The plurality of first grasping components 212 are used for clamping the O-ring. The first detection component 213 is installed on the first grasping bracket 211 and is used for detecting whether the O-ring is expanded. It can be understood that during the actual working process, the transverse movement module 220 drives the first grasping bracket 211 to move to the detection position, and the first detection component 213 detects whether the O-ring on the storage column 130 is expanded, so as to avoid the phenomenon that the O-ring is grasped without being expanded, resulting in assembly failure or assembly defects. When the first detection component 213 detects that the O-ring is expanded, the transverse movement module 220 continues to drive the first grasping bracket 211 to move it to the position corresponding to the O-ring. After the plurality of first grasping components 212 clamp the O-ring, the transverse movement module 220 drives the first grasping bracket 211 to transport it to the assembly position. By grasping the O-ring with the plurality of first grasping components 212, on the one hand, it can ensure that the O-ring grasping module 210 can remove the O-ring from the storage column 130, and on the other hand, it can make the O-ring deform uniformly, avoiding assembly failure or assembly defects caused by non-uniform deformation of the O-ring.

[0041] Optionally, referring to Figure 4 As shown, the first grasping bracket 211 is composed of a first plate, a second plate, a third plate, and a fourth plate. The mating hole 2111 is arranged on the first plate. The second plate and the third plate are respectively connected to the top and bottom of the first plate through connecting bolts. The fourth plate is connected to the first plate, the second plate, and the third plate and cooperates with the transverse movement module 220. The first grasping bracket 211 formed by splicing the first plate, the second plate, the third plate, and the fourth plate simplifies the structure of the first grasping bracket 211, facilitates the assembly of the first grasping bracket 211, and reduces the manufacturing cost of the first grasping bracket 211. Of course, in an alternative embodiment of the present invention, the first grasping bracket 211 can also be a frame structure welded by a plurality of plate-like structures or other frame structures, which is not limited to the above definition.

[0042] Optionally, referring to Figure 4As shown, each first grasping component 212 includes a grasping base 2121, a fixed jaw 2122, a movable jaw 2123 and a jaw driving member 2124. The grasping base 2121 is installed on the first grasping bracket 211, the fixed jaw 2122 is installed on the grasping base 2121, and the jaw driving member 2124 is installed on the grasping base 2121 and is connected to the movable jaw 2123 to drive the movable jaw 2123 to move in a direction approaching or away from the fixed jaw 2122. It can be understood that during the actual working process, when the cross-moving module 220 drives the first grasping bracket 211 to move to a specified position, the fixed jaw 2122 abuts against the inner wall of the O-ring. At this time, the jaw driving member 2124 drives the movable jaw 2123 to abut against the outer wall of the O-ring, and the clamping of the O-ring can be completed. This clamping method can not only conveniently clamp the O-ring but also ensure the stability of the O-ring. Of course, it should be supplemented here that in other embodiments of the present invention, the first grasping component 212 can also be formed into other structures such as a finger cylinder or an electric gripper, etc., which are not limited to the foregoing.

[0043] Reference Figure 5 As shown, the cylinder liner grasping module 310 includes a second grasping bracket 311, a second grasping component 312 and a plurality of limiting rods 313. The second grasping bracket 311 is cooperated with the end of the robot through a quick-change disk. The second grasping component 312 is installed on the second grasping bracket 311 and is used to extend into the inner hole of the cylinder liner to grasp the cylinder liner. The plurality of limiting rods 313 are arranged at intervals on the second grasping bracket 311 and are located outside the second grasping component 312. The plurality of limiting rods 313 can abut against the inner hole wall of the cylinder liner. It can be understood that since the second grasping bracket 311 is cooperated with the end of the robot through a quick-change disk, in the actual working process, the robot can quickly replace the appropriate cylinder liner grasping module 310 according to the signal given by the control mechanism, so that the cylinder liner O-ring assembly equipment of this embodiment can be compatible with cylinder liners of different sizes and improve the applicable range. And during the actual working process, the robot drives the second grasping bracket 311 to a specified position. The plurality of limiting rods 313 can abut against the inner hole wall of the cylinder liner, and the second grasping component 312 can extend into the inner hole of the cylinder liner and can abut against the inner side wall of the cylinder liner. The cylinder liner can be conveniently taken out from the specified position through the common support of the second grasping component 312 and the limiting rods 313. At the same time, since the second grasping component 312 of this embodiment grasps the cylinder liner by cooperating with the inner hole of the cylinder liner and does not contact the outer peripheral wall of the cylinder liner, there will be no interference when driving the cylinder liner through the O-ring and no adverse effect on the assembly of the O-ring.

[0044] Optionally, the second grasping component 312 includes a grasping cylinder 3121, a grasping driving member 3123, and a second detection component. The grasping cylinder 3121 has a plurality of movable blocks 3122. The grasping cylinder 3121 can drive the plurality of movable blocks 3122 to move radially along the grasping cylinder 3121 so that the movable blocks 3122 abut against the inner hole wall of the cylinder liner. The grasping driving member 3123 is installed on the second grasping bracket 311 and is used to drive the grasping cylinder 3121 to move axially along the limiting rod 313. The second detection component is installed on the second grasping bracket 311 and is used for detecting the in-place of the cylinder liner. It can be understood that during the actual working process, the grasping driving member 3123 drives the grasping cylinder 3121 to extend into the inner hole of the cylinder liner, and then the grasping cylinder 3121 acts to drive the plurality of movable blocks 3122 to move and abut against the inner hole wall of the cylinder liner. The grasping driving member 3123 drives the grasping cylinder 3121 to retract and makes the limiting rod 313 abut against the inner hole wall of the cylinder liner. When the second detection component detects the cylinder liner, it means that the cylinder liner has been taken out, and the robot can drive the cylinder liner grasping module 310 to move to the assembly position. It should be noted that the second detection component can select structures such as proximity switches and infrared detectors according to actual needs, and the specific type and control logic of the second detection component are not specifically limited here.

[0045] Further optionally, a buffer pad 3124 is provided on the movable block 3122. This can avoid the direct contact between the movable block 3122 and the inner hole wall of the cylinder liner, thereby avoiding the phenomenon that the inner hole wall of the cylinder liner is scratched.

[0046] Optionally, the second grasping bracket 311 includes two support plates and a support column connected between the two support plates. The grasping driving member 3123 is installed between the two support plates. Thus, the grasping driving member 3123 can be hidden to avoid being bumped.

[0047] Optionally, the cross-movement module 220 includes a cross-movement bracket, a cross-movement lead screw, a cross-movement driving member, and a cross-movement nut. The two ends of the cross-movement lead screw are rotatably connected to the cross-movement bracket. The cross-movement driving member is installed on the cross-movement bracket and is connected to the cross-movement lead screw. The cross-movement nut is threadedly connected to the cross-movement lead screw and cooperates with the O-ring grasping module 210. It can be understood that using the lead screw-nut pair composed of the cross-movement lead screw and the cross-movement nut as the driving component of the O-ring grasping module 210 can, on the one hand, enable the O-ring grasping module 210 to move smoothly during actual work, and on the other hand, enable precise control of the O-ring grasping module 210, thereby ensuring the smooth assembly of the O-ring.

[0048] Reference Figure 1As shown in the figure, the cylinder liner O-ring assembly equipment further includes a defective product temporary storage table 400, which is arranged at an interval from the detection device and is used to receive the cylinder liner sleeved with an O-ring that fails to pass the detection of the detection device. It can be understood that during the actual working process, the robot drives the cylinder liner grasping module 310 to move the cylinder liner sleeved with an O-ring to the detection area of the detection device for photographing and detecting the cylinder liner sleeved with an O-ring; if the assembly is unqualified, the robot drives the cylinder liner grasping module 310 to place it on the defective product temporary storage table 400, and the control mechanism sends a signal to remind the operator to perform detection and correction. Thus, it is possible to prevent unqualified products from flowing to the next process and improve the yield of engine cylinder block assembly.

[0049] The working process of the cylinder liner O-ring assembly equipment in this embodiment is as follows:

[0050] The first step: The end of the robot moves to the position corresponding to the cylinder liner grasping module 310 and cooperates with the appropriate cylinder liner grasping module 310 according to the size of the cylinder liner.

[0051] The second step: The rotation driving member 110 drives the storage column 130 installed with a specified size to rotate to a position parallel to the transverse movement direction of the transverse movement module 220.

[0052] The third step: The transverse movement module 220 drives the O-ring grasping module 210 to move to the detection position, and the first detection component 213 detects whether the O-ring on the storage column 130 is expanded.

[0053] The fourth step: The transverse movement module 220 drives the O-ring grasping module 210 to the end of the storage column 130 to grasp a specified size O-ring.

[0054] The fifth step: The transverse movement module 220 drives the O-ring grasping module 210 to the assembly position.

[0055] The sixth step: The robot drives the cylinder liner grasping module 310 to grasp the specified size cylinder liner and drives the cylinder liner to pass through the O-ring.

[0056] The seventh step: The O-ring grasping module 210 releases the O-ring to complete the assembly of the cylinder liner and the O-ring.

[0057] The eighth step: The robot drives the cylinder liner grasping module 310 to move the cylinder liner sleeved with an O-ring to the detection area of the detection device for photographing and detecting the cylinder liner sleeved with an O-ring.

[0058] If the assembly is unqualified, the robot drives the cylinder liner grasping module 310 to place it on the defective product temporary storage table 400, and the control mechanism sends a signal to remind the operator to perform detection and correction.

[0059] If the assembly is qualified, the control mechanism sends a signal, and then the robot drives the cylinder liner grasping module 310 to place it into the cylinder block pressing device 500 for pressing.
