Detailed implementation manners

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] As Figures 1 - 3 shown, the present invention discloses a full-automatic press-fitting machine for engine cylinder head seat rings, including a first feeding mechanism 1, a second feeding mechanism 2, and a press-fitting mechanism 3. The first feeding mechanism 1 is used to convey a press-fitting part 4 to the press-fitting mechanism 3, the second feeding mechanism 2 is used to convey a press-in part 5 to the press-fitting mechanism 3, and the press-fitting mechanism 3 is used to press-fit the press-in part 5 into the press-fitting part 4. The second feeding mechanism 2 is respectively provided with a receiving position 211, a press-fitting position 212, and a rotating assembly 24. The rotating assembly 24 is used to push the press-in part 5 located in the receiving position 211 along an arc into the press-fitting position 212. The press-fitting head 31 in the press-fitting mechanism 3, the press-fitting part 4, and the press-fitting position 212 are arranged vertically corresponding to each other. Among them, a gate assembly 25 is rotatably connected to the press-fitting position 212. The gate assembly 25 abuts against the bottom of the press-in part 5 to support the press-in part 5. The gate assembly 25 rotates and avoids interference as the press-fitting head 31 moves downward, so that the press-fitting head 31 can drive the press-in part 5 to pass through the press-fitting position 212 and press-fit into the press-fitting part 4.

[0038] In this embodiment, the press-fitting part 4 is an engine cylinder head, and the press-in part 5 is a seat ring. The seat ring needs to be press-fitted into the engine cylinder head through the press-fitting mechanism 3. Since the seat ring is of an annular structure, both the receiving position 211 and the press-fitting position 212 are circular structures adapted to the press-in part 5. And since the press-fitting machine of the present invention is a vertical press-fitting machine, the press-fitting position 212 is provided with upper and lower through holes. When the press-in part 5 falls into the press-fitting position 212, it will not directly fall under the action of the gate assembly 25. When the press-fitting head 31 moves downward, the press-fitting head 31 has a downward thrust on the gate assembly 25. Under the action of this thrust, the gate assembly 25 rotates downward to avoid interference, so that the press-fitting head 31 can drive the press-in part 5 to pass through the press-fitting position 212 and press-fit into the press-fitting part 4. When the press-fitting is completed, the press-fitting head 31 moves upward, and the gate assembly 25 will automatically reset without external force. Thus, the full automation of the press-fitting is realized, and there is no need for manual feeding, resulting in higher production efficiency and safety.

[0039] Preferably, the press-fitting mechanism 3 also includes a stamping drive component 32, which is used to drive the press-fitting head 31 to move up and down. A magnetic suction component 311 is also provided in the press-fitting head 31. As the press-fitting head 31 moves downward, the press-fitting component 5 will be adsorbed on the press-fitting head 31 under the suction force of the magnetic suction component 311, preventing the press-fitting component 5 from falling directly from the press-fitting position 212 after the gate assembly 25 evades, causing damage to the material.

[0040] Furthermore, if Figures 4 - 5 As shown, the second feeding mechanism 2 includes a fixed plate 21, the material receiving position 211, the press-fitting position 212 and the rotating assembly 24 are all arranged on the fixed plate 21, the rotating assembly 24 includes a rotating plate 241 and a rotating driving member 242, one end of the rotating plate 241 is provided with a rotating groove 2412 adapted to the press-fitting member 5, and the other end is provided with a rotating center 2411, the output shaft of the rotating driving member 242 passes through the fixed plate 21 and is connected to the rotating center 2411, and the rotating plate 241 takes the rotating center 2411 as the center of the circle at the material receiving position 211 and the pressing position 212 on the fixed plate 21 The press-fitting position 212 rotates and moves, and when the rotating groove 2412 coincides with the material receiving position 211, the press-fitting piece 5 falls into the material receiving position 211 and automatically falls into the rotating groove 2412. As the rotating plate 241 rotates, the press-fitting piece 5 rotates along an arc in the rotating groove 2412. When the rotating groove 2412 coincides with the press-fitting position 212, the press-fitting piece 5 automatically falls from the rotating groove 2412 into the press-fitting position 212, so as to realize the automatic switching of the press-fitting piece 5 from the material receiving position 211 to the press-fitting position 212. The structure is simple and the operability is stronger.

[0041] Preferably, in order to reduce the resistance of the press-in member 5 during the rotation and movement, a slideway 26 arranged along an arc is further provided between the fixed plate 21 and the rotating plate 241. The slideway 26 is made of a material with a smooth surface and good wear resistance. The arrangement of the slideway 26 can reduce the friction of the press-in member 5 during the movement, avoid wear and scratches of the press-in member 5 caused by friction, and thus make the rotation accuracy of the rotating plate 241 higher. The slideway 26 is also provided with a discharge port 261 corresponding to the press-fitting position 212, so that the press-in member 5 can pass through the slideway 26 from the rotating groove 2412 and fall into the press-fitting position 212 through the discharge port 261.

[0042] Further, two limit blocks 27 are also provided on the fixed plate 21. One of the limit blocks 27 is arranged between the rotation center 2411 and the material receiving position 211, and the other limit block 27 is arranged between the rotation center 2411 and the press-fitting position 212. The two limit blocks 27 are respectively used to abut against both sides of the rotating plate 241. When the rotating plate 241 rotates and moves from the material receiving position 211 towards the press-fitting position 212 and the rotating groove 2412 coincides with the press-fitting position 212, the limit block 27 between the rotation center 2411 and the press-fitting position 212 abuts against the side of the rotating plate 241, so that the rotating plate 241 cannot move further, so as to realize the precise docking of the rotating groove 2412 and the press-fitting position 212; when the rotating plate 241 rotates and moves from the press-fitting position 212 towards the material receiving position 211 and the rotating groove 2412 coincides with the material receiving position 211, the limit block 27 between the rotation center 2411 and the material receiving position 211 abuts against the other side of the rotating plate 241, so that the rotating plate 241 cannot move further, so as to realize the precise docking of the rotating groove 2412 and the material receiving position 211.

[0043] Furthermore, as Figures 5 - 7 shown, there are two gate assemblies 25, which are symmetrically arranged at the bottom of the press-fitting position 212, and include a support plate 251 and a fixed block 252 that are screwed together. An installation groove 213 is provided on the fixed plate 21. The fixed block 252 is installed in the installation groove 213 and is rotatably connected to the fixed plate 21. A counterweight portion 253 extends obliquely on the side of the fixed block 252 facing away from the support plate 251. The counterweight portion 253 is screwed and fixed to the fixed block 252, and the counterweight portion 253 forms an angle a with the bottom of the fixed plate 21. When the press-fitting member 5 falls into the press-fitting position 212, it is elastically supported by the support plate 251, that is, the bottom of the press-fitting member 5 abuts against the upper end surface of the support plate 251, and the sum of the weights of the press-fitting member 5 and the support plate 251 is less than the weight of the counterweight portion 253, so that the counterweight portion 253 always keeps the support plate 251 pressed against the bottom surface of the fixed plate 21, thereby realizing the supporting effect on the press-fitting member 5; when the press-fitting head 31 pushes the support plate 251 downward, the counterweight portion 253 will approach the fixed plate 21, that is, the angle a will gradually become smaller until the press-fitting member 5 can smoothly pass through the press-fitting position 212; when the press-fitting head 31 resets upward, under the action of the counterweight portion 253, the angle a will gradually become larger until the support plate 251 is limited and abuts against the bottom of the fixed plate 21.

[0044] Preferably, in some embodiments, two gate assemblies 25 are provided and symmetrically arranged at the bottom of the press-fitting position 212. The gate assemblies 25 include a support plate 251 and a fixing block 252 that are screwed together. An installation groove 213 is provided on the fixing plate 21. The fixing block 252 is installed in the installation groove 213. An elastic member (not shown in the drawings) is provided between the support plate 251 and the fixing plate 21 or the fixing block 252. Under the action of the elastic member, the support plate 251 and the fixing plate 21 are kept in a state of abutting against each other without external force, so that the support plate 251 can support the press-fitting member 5 when the press-fitting member 5 falls into the press-fitting position 212. As the press-fitting head 31 moves downward and pushes the support plate 251, the elastic member is in a compressed state. The support plate 251 can rotate downward under the action of the compression of the elastic member to avoid the press-fitting member 5; when the press-fitting head 31 resets upward, the elastic member automatically resets and extends, and elastically presses the support plate 251 to keep it in a state of abutting against the bottom of the fixing plate 21 to achieve the support effect; since the use of an elastic member, such as a spring, will cause problems such as wear and rust during long-term use, resulting in a short service life and insufficient elastic force, which will affect both the press-fitting effect and efficiency. Therefore, the reset scheme using the counterweight portion 253 does not have the defect of the service life of the reset scheme using a spring and is a better scheme.

[0045] Further, as Figure 8 shown, the second feeding mechanism 2 further includes a vibrating tray 22 and a detection assembly 23. A detection position 2321 corresponding to the discharge end of the vibrating tray 22 is provided on the detection assembly 23. The output end of the detection assembly 23 corresponds to the receiving position 211. The vibrating tray 22 is arranged on the side of the press-fitting mechanism 3 and is used to carry the press-fitting member 5 and vibrate and discharge it. The detection assembly 23 is arranged on one side of the vibrating tray 22 where the material is discharged. The detection position 2321 corresponds to the discharge end of the vibrating tray 22 to facilitate timely and rapid detection and improve the feeding efficiency; the detection assembly 23 includes an upper slide plate 231, a lower slide plate 232, a lateral driving member 233 and a detection module 234. The detection module 234 is located above the detection position 2321. The lateral driving member 233 is connected to the upper slide plate 231 and drives the upper slide plate 231 to move on the lower slide plate 232. The detection module 234 includes a connecting rod and a light source and an industrial camera sequentially arranged on the connecting rod from bottom to top. The detection module 234 is used to detect whether there are defects, flaws, etc. in the press-fitting member 5;

[0046] Specifically, as Figures 9 - 10As shown, the detection position 2321 is arranged on the lower slide plate 232, and a "U"-shaped groove 2311 corresponding to the detection position 2321 and opening towards the discharging end of the vibrating tray 22 is arranged on the upper slide plate 231. When the pressing member 5 vibrates out of the vibrating tray 22, it will fall on the detection position 2321 and be limited and fixed by the "U"-shaped groove 2311, so that the pressing member 5 can move along with the movement of the upper slide plate 231; to prevent the pressing member 5 from sliding out from the opening side of the "U"-shaped groove 2311 when moving on the lower slide plate 232, a limiting plate 2324 extending upward is arranged on the side of the lower slide plate 232 corresponding to the opening of the "U"-shaped groove 2311, so that the "U"-shaped groove 2311 of the upper slide plate 231 forms a closed space with the limiting plate 2324 during the movement process to fix the pressing member 5 in the "U"-shaped groove 2311 and improve the conveying efficiency.

[0047] Further, a blanking hole 2322 corresponding to the "U"-shaped groove 2311 is arranged at one end of the lower slide plate 232, and a waste hole 2323 is arranged at the other end. A waste box 2325 is also arranged below the waste hole 2323. The blanking hole 2322, the "U"-shaped groove 2311 and the waste hole 2323 are arranged in a vertically staggered manner. When the pressing member 5 enters the detection position 2321, the detection module 234 performs detection. When it is determined that the pressing member 5 is a qualified product, the lateral driving member 233 will drive the upper slide plate 231 to move towards the receiving position 211. When the "U"-shaped groove 2311 coincides with the receiving position 211, the pressing member 5 in the "U"-shaped groove 2311 will fall into the receiving position 211; when the detection module 234 detects that the pressing member 5 is an unqualified product, the lateral driving member 233 will drive the upper slide plate 231 to move towards the waste hole 2323. When the "U"-shaped groove 2311 coincides with the waste hole 2323, the pressing member 5 in the "U"-shaped groove 2311 will pass through the waste hole 2323 and fall into the waste box 2325, thereby realizing the screening effect of the pressing member 5.

[0048] Even further, as Figures 11 - 12As shown in the figure, the first feeding mechanism 1 includes a robotic arm 11 and a clamping assembly 12 rotatably connected to the robotic arm 11. The robotic arm 11 can move omnidirectionally, facilitating the unobstructed conveyance of the press-fitting part 4 to the press-fitting mechanism 3. The clamping assembly 12 includes a connecting plate 121 and two identically structured clamping arms 122. The two clamping arms 122 are respectively arranged at both ends of the connecting plate 121 and on the same side of the connecting plate 121. On the other side of the connecting plate 121 facing the robotic arm 11, there are also two third driving members 13 corresponding to the two clamping arms 122 respectively. The two third driving members 13 are used to control the opening and closing of the two clamping arms 122. Among them, the output ends of the two third driving members 13 both face the two ends of the connecting plate 121 and are respectively connected and fixed to the corresponding clamping arms 122. When it is necessary to clamp the press-fitting part 4, the output shafts of the two third driving members 13 extend outwards, so that the two clamping arms 122 move away from each other and are in an open state. By moving the robotic arm 11 and rotating the clamping assembly 12, after the press-fitting part 4 is placed between the two clamping arms 122, the output shafts of the two third driving members 13 contract inwards, so that the two clamping arms 122 respectively clamp and fix the two ends of the press-fitting part 4, and then the robotic arm 11 is driven to move, thus achieving the effect of automatically feeding the press-fitting part 4. The third driving member 13 can be a cylinder, a motor, a lead screw or other parts capable of realizing the telescopic function.

[0049] Preferably, the press-fitting part 4 is provided with a groove 41, and on the opposite sides of the two clamping arms 122, there are protrusions 1221 adapted to the groove 41. When clamping, the protrusions 1221 are inserted into the groove 41 to form a limit for the press-fitting part 4, making the clamping force of the two clamping arms 122 firmer. Furthermore, it is ensured that during the conveyance process, the risk of the press-fitting part 4 falling due to unstable clamping is reduced. At the same time, the conveyance efficiency of the press-fitting part 4 can also be higher, thereby improving the overall production efficiency.

[0050] Furthermore, as Figure 1 、 Figure 13As shown, the press-fitting mechanism 3 further includes a frame 34 and a press-fitting table 33 disposed on the frame 34 corresponding to the press-fitting head 31 up and down. After the press-fitting part 4 is transferred, it is placed on the press-fitting table 33. Since there are multiple press-fitting stations 42 on the press-fitting part 4, during the press-fitting process, it is necessary to continuously adjust the position of the press-fitting part 4 so that each station 42 corresponds to the press-fitting position 212 and the press-fitting head 31. Therefore, a first moving component 331 moving along the X-axis direction and a second moving component 332 moving along the Y-axis direction are respectively provided at the bottom of the press-fitting table 33. A moving plate 36 is provided between the first moving component 331 and the second moving component 332. The second moving component 332 is fixedly provided on the upper end surface of the moving plate 36. Among them, the first moving component 331 includes a first slide rail 3311, a first slider 3312, and a first driving member 3313. The first slider 3312 is fixedly connected to the lower end surface of the moving plate 36. The first driving member 3314 is used to drive the first slider 3312 to slide on the first slide rail 3311 to drive the moving plate 36 to move in the X-axis direction, so as to achieve the effect of the second moving component 332 and the press-fitting part 4 located on the second moving component 332 moving in the X-axis direction; the second moving component 332 includes a second slide rail 3321, a second slider 3322, and a second driving member 3323 fixedly connected to the moving plate 36. The second slider 3322 is fixedly connected to the lower end surface of the press-fitting table 33. The second driving member 3324 is used to drive the second slider 3322 to slide on the second slide rail 3321 to drive the press-fitting table 33 to move in the Y-axis direction, so as to achieve the effect of the press-fitting part 4 moving in the X-axis and Y-axis directions so that each station 42 corresponds to the press-fitting position 212 and press-fitting is performed, eliminating the need for manual alignment adjustment, saving time and effort, greatly improving the press-fitting efficiency, and realizing the full automation of press-fitting.

[0051] Preferably, protective covers 35 are provided above both the first moving component 331 and the second moving component 332. The protective covers 35 can be folded or stretched as they move, which can prevent dust or debris from falling on the first moving component 331 and the second moving component 332, resulting in jamming or malfunction of the movement of the press-fitting part 4, thereby affecting the accuracy of press-fitting.

[0052] The working principle of the present invention is described in detail as follows:

[0053] During use, the press-fitting part 4 is clamped by the clamping assembly 12 and transferred to the press-fitting table 33 under the drive of the robotic arm 11. Under the adjustment of the first moving assembly 331 and the second moving assembly 332, the press-fitting station 42 on the press-fitting part 4 can be aligned with the press-fitting position 212 and wait for press-fitting. At the same time, after the press-in part 5 vibrates and discharges from the vibrating tray 22, it will fall on the detection position 2321 and be detected by the detection module 234. The qualified products will be driven by the lateral driving part 233 to move the upper slide plate 231 to the material receiving position 211, and the unqualified ones will be moved to the waste hole 2323. The press-in part 5 falling in the material receiving position 211 will simultaneously fall into the rotating groove 2412 of the rotating plate 241. Under the action of the rotation driving part 242, the rotating plate 241 drives the press-in part 5 to move along the arc of the slideway 26. When the rotating groove 2412 coincides with the press-fitting position 212, the press-in part 5 will automatically fall on the press-fitting position 212 and be supported by the gate assembly 25. Then, under the drive of the stamping driving part 32, the press-fitting head 31 moves downward. As the press-fitting head 31 moves, the press-in part 5 will automatically adsorb on the press-fitting head 31, and the gate assembly 25 will rotate downward under the top push of the press-fitting head 31 to make way, so that the press-fitting head 31 can drive the press-in part 5 through the press-fitting position 212 and perform press-fitting with the press-fitting part 4 located below the press-fitting position 212. After each press-fitting station 42 is press-fitted, the press-fitting part 4 will be automatically adjusted again to align another press-fitting station 42 with the press-fitting position 212 and continue the press-fitting, thereby realizing the full-automatic press-fitting of the machine.
