Technical Field

[0001] This invention belongs to the field of automobile manufacturing technology, specifically relating to a fully automatic press-fitting machine for engine cylinder head seat rings. Background Technology

[0002] In the automotive manufacturing industry, the engine is a core component of a car, and its quality directly affects the overall performance of the car. The engine cylinder head is one of the key components of the engine. To ensure the quality of the engine cylinder head, it is necessary to ensure the pressing quality of the engine cylinder head and the cylinder head seat. If the cylinder head is not pressed in place or there are gaps on the mating surface, it may lead to problems such as valve detachment and excessive oil consumption.

[0003] In the current technology, the pressing of engine cylinder heads and bearing rings still requires some manual operation. However, the engine cylinder head has a complex structure and many holes that need to be pressed. Repeated manual operation is difficult and can easily lead to fatigue, resulting in installation errors or inaccurate alignment. This makes it difficult to guarantee the pressing quality and results in extremely low production efficiency. Summary of the Invention

[0004] (1) Technical problems to be solved This invention discloses a fully automatic press-fitting machine for engine cylinder head bearings, which aims to solve the problems of low production efficiency and poor accuracy caused by the need for manual feeding or adjustment of the press-fitting position.

[0005] (2) Technical solution This invention discloses a fully automatic press-fitting machine for engine cylinder head seat rings, comprising a first feeding mechanism, a second feeding mechanism, and a pressing mechanism. The first feeding mechanism is used to feed a pressing component to the pressing mechanism, the second feeding mechanism is used to feed a pressing-in component to the pressing mechanism, and the pressing mechanism is used to press the pressing-in component into the pressing component. The second feeding mechanism is respectively provided with a receiving position, a pressing position, and a rotating assembly. The rotating assembly is used to push the pressing-in component located in the receiving position along an arc into the pressing position. The pressing head, the pressing component, and the pressing position in the pressing mechanism are arranged vertically in a corresponding manner. A gate assembly is rotatably connected to the pressing position. The gate assembly is placed against the bottom of the pressing member. The gate assembly rotates and moves away as the pressing head moves down, so that the pressing head can drive the pressing member through the pressing position and press it into the pressing member.

[0006] Furthermore, the second feeding mechanism includes a fixed plate, and the receiving position, pressing position and the rotating assembly are all disposed on the fixed plate. The rotating assembly includes a rotating plate and a rotating drive. One end of the rotating plate is provided with a rotation center, and the output shaft of the rotating drive passes through the fixed plate and is connected to the rotation center. The other end is provided with a rotating groove adapted to the pressing part. The rotating groove is used to transport the pressing part from the receiving position to the pressing position.

[0007] Furthermore, a slide rail is provided between the fixed plate and the rotating plate along an arc, with the two ends of the slide rail corresponding to the receiving position and the pressing position, respectively, and the slide rail is provided with a discharge port corresponding to the pressing position.

[0008] Furthermore, the fixed plate is provided with two limiting blocks, one of which is located between the rotation center and the receiving position, and the other is located between the rotation center and the pressing position. The two limiting blocks are respectively used to abut against the two sides of the rotating plate.

[0009] Furthermore, the gate assembly has two symmetrically arranged at the bottom of the pressing position, including a support plate and a fixing block that are screwed together. The fixing block is rotatably connected to the fixing plate. The side of the fixing block away from the support plate is provided with a counterweight. The counterweight forms an angle α with the bottom of the fixing plate.

[0010] Furthermore, the second feeding mechanism also includes a vibrating feeder and a detection component. The detection component has a detection position corresponding to the discharge end of the vibrating feeder, and the output end of the detection component corresponds to the receiving position.

[0011] Furthermore, the detection component includes an upper slide plate, a lower slide plate, a lateral drive component, and a detection module. The detection module is located above the detection position, and the lateral drive component is connected to the upper slide plate and drives the upper slide plate to move on the lower slide plate. The detection position is located on the sliding plate, and the upper sliding plate is provided with a "U"-shaped groove corresponding to the detection position. One end of the lower sliding plate is provided with a feeding hole, and the other end is provided with a waste hole. The feeding hole, the "U"-shaped groove, and the waste hole are arranged alternately.

[0012] Furthermore, the first feeding mechanism includes a robotic arm and a clamping assembly rotatably connected to the robotic arm. The clamping assembly includes a connecting plate and two clamping arms with the same structure. The two clamping arms are respectively disposed at both ends of the connecting plate and located on the same side of the connecting plate. The other side of the connecting plate is also provided with a third driving member corresponding to the two clamping arms respectively. The third driving member is used to control the opening and closing of the two clamping arms.

[0013] Furthermore, the press-fit component is provided with a groove, and the two clamping arms are provided with a protrusion on the opposite side that matches the groove.

[0014] Furthermore, the pressing mechanism also includes a pressing platform corresponding to the pressing head. The bottom of the pressing platform is provided with a first moving component and a second moving component arranged along the X-axis and Y-axis directions, respectively. The pressing component is provided with multiple pressing stations. The first moving component and the second moving component are used to drive the pressing component to move so that the station corresponds to the pressing position.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: A first and second feeding mechanism are set up to automate the feeding of pressing parts and pressing components, eliminating the need for manual operation and greatly improving feeding efficiency. At the same time, a rotating component is set up to rotate and transport the pressing components to the pressing position, and a gate component is set below the pressing position so that the pressing components falling into the pressing position can be elastically supported by the gate component and will not fall immediately. As the pressing head moves downward, the pressing components are attracted to the pressing head, while the gate component moves downward to avoid it, so that the pressing head can carry the pressing components through the pressing position and press them with the pressing components located below the pressing position, realizing automated pressing production and higher production efficiency. In addition, a first moving component and a second moving component are provided at the bottom of the pressing component to drive the pressing component to move in different directions, so as to realize the automatic corresponding adjustment of different pressing stations and pressing positions on the pressing component, and make the pressing more accurate.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1-3 As shown, this invention discloses a fully automatic press-fitting machine for engine cylinder head seat rings, including a first feeding mechanism 1, a second feeding mechanism 2, and a pressing mechanism 3. The first feeding mechanism 1 is used to feed a pressing component 4 to the pressing mechanism 3, and the second feeding mechanism 2 is used to feed a pressing component 5 to the pressing mechanism 3. The pressing mechanism 3 is used to press the pressing component 5 into the pressing component 4. The second feeding mechanism 2 is respectively provided with a receiving position 211, a pressing position 212, and a rotating assembly 24. The rotating assembly 24 is used to press the component 5 located at the receiving position 211 into the pressing component 4. The press-in component 5 is pushed into the press-fit position 212 along the arc. The press-fit head 31, the press-fit component 4, and the press-fit position 212 in the press-fit mechanism 3 are arranged vertically and vertically respectively. A gate assembly 25 is rotatably connected to the press-fit position 212. The gate assembly 25 is placed against the bottom of the press-in component 5 to support the press-in component 5. The gate assembly 25 rotates and moves away as the press-fit head 31 moves down, so that the press-fit head 31 can drive the press-in component 5 through the press-fit position 212 and press it into the press-fit component 4.

[0032] In this embodiment, the press-fit component 4 is an engine cylinder head, and the press-fit component 5 is a seat ring. The seat ring needs to be press-fitted into the engine cylinder head by the press-fit mechanism 3. Since the seat ring has an annular structure, both the receiving position 211 and the press-fit position 212 are circular structures adapted to the press-fit component 5. Furthermore, the press-fit machine of this invention is a vertical press-fit machine, so the press-fit position 212 is vertically continuous. When the press-fit component 5 falls into the press-fit position 212, it will not fall directly under the action of the gate assembly 25. When the pressing head 31 moves downward, it exerts a downward pushing force on the gate assembly 25. Under this pushing force, the gate assembly 25 rotates downward to avoid a misalignment, allowing the pressing head 31 to drive the pressing member 5 through the pressing position 212 and press it into the pressing member 4. After pressing is completed, the pressing head 31 moves upward, and the gate assembly 25 automatically resets without external force. Thus, the pressing is fully automated, eliminating the need for manual feeding and improving production efficiency and safety.

[0033] Preferably, the pressing mechanism 3 further includes a stamping drive 32, which is used to drive the pressing head 31 to move up and down. The pressing head 31 is also provided with a magnetic suction member 311. As the pressing head 31 moves downward, the pressing member 5 will be attracted to the pressing head 31 by the magnetic suction member 311, preventing the pressing member 5 from falling directly from the pressing position 212 after the gate assembly 25 avoids it, thus preventing damage to the material.

[0034] Furthermore, such as Figure 4-5 As shown, the second feeding mechanism 2 includes a fixed plate 21. The receiving position 211, the pressing position 212, and the rotating assembly 24 are all disposed on the fixed plate 21. The rotating assembly 24 includes a rotating plate 241 and a rotating drive 242. One end of the rotating plate 241 is provided with a rotating groove 2412 adapted to the pressing member 5, and the other end is provided with a rotating center 2411. The output shaft of the rotating drive 242 passes through the fixed plate 21 and is connected to the rotating center 2411. The receiving position 211 and the pressing position 212 on the fixed plate 21 are arranged around the rotating center 2411. The pressing positions 212 rotate and move between each other. When the rotating groove 2412 coincides with the receiving position 211, the pressing part 5 falls into the receiving position 211 and automatically falls into the rotating groove 2412. As the rotating plate 241 rotates, the pressing part 5 rotates along an arc in the rotating groove 2412. When the rotating groove 2412 coincides with the pressing position 212, the pressing part 5 automatically falls from the rotating groove 2412 into the pressing position 212, so as to realize the automatic switching of the pressing part 5 from the receiving position 211 to the pressing position 212. The structure is simple and the operability is stronger.

[0035] Preferably, to reduce the resistance of the press-in member 5 during rotational movement, a slide 26 arranged along an arc is provided between the fixed plate 21 and the rotating plate 241. The slide 26 is made of a smooth material with good wear resistance. The slide 26 reduces friction during the movement of the press-in member 5, preventing wear and scratches caused by friction, thereby improving the rotational accuracy of the rotating plate 241. The slide 26 is also provided with a discharge port 261 corresponding to the pressing position 212, allowing the press-in member 5 to pass through the discharge port 261 from the rotating groove 2412, pass through the slide 26, and fall into the pressing position 212.

[0036] Furthermore, the fixed plate 21 is also provided with two limiting blocks 27, one of which is located between the rotation center 2411 and the receiving position 211, and the other is located between the rotation center 2411 and the pressing position 212. The two limiting blocks 27 are respectively used to abut against the two sides of the rotating plate 241. When the rotating plate 241 rotates and moves from the receiving position 211 to the pressing position 212 and the rotating groove 2412 coincides with the pressing position 212, the limiting block 27 located between the rotation center 2411 and the pressing position 212... The limiting block 27 abuts against the side of the rotating plate 241, preventing the rotating plate 241 from moving further, thereby achieving precise docking between the rotating groove 2412 and the pressing position 212; when the rotating plate 241 rotates from the pressing position 212 towards the receiving position 211 and the rotating groove 2412 coincides with the receiving position 211, the limiting block 27 located between the rotation center 2411 and the receiving position 211 abuts against the other side of the rotating plate 241, preventing the rotating plate 241 from moving further, thereby achieving precise docking between the rotating groove 2412 and the receiving position 211.

[0037] Furthermore, such as Figure 5-7 As shown, the gate assembly 25 has two symmetrically arranged at the bottom of the pressing position 212, including a support plate 251 and a fixing block 252 screwed together. The fixing plate 21 has a mounting groove 213, and the fixing block 252 is installed in the mounting groove 213 and rotatably connected to the fixing plate 21. The fixing block 252 has a counterweight 253 extending obliquely on the side away from the support plate 251. The counterweight 253 is screwed to the fixing block 252, and the counterweight 253 forms an angle α with the bottom of the fixing plate 21. When the pressing part 5 falls into the pressing position 212, it is elastically supported by the support plate 251, that is, the bottom of the pressing part 5 is flush with the support plate 251. The upper surface of the support plate 251 abuts against the support plate 251, and the sum of the weights of the press-in member 5 and the support plate 251 is less than the weight of the counterweight 253, so that the counterweight 253 always keeps the support plate 251 pressed against the bottom surface of the fixed plate 21, thereby achieving the supporting function of the press-in member 5; when the pressing head 31 pushes the support plate 251 downward, the counterweight 253 will move closer to the fixed plate 21, that is, the included angle α will gradually decrease until the press-in member 5 can pass smoothly through the pressing position 212; when the pressing head 31 returns to its original position upward, under the action of the counterweight 253, the included angle α will gradually increase until the support plate 251 and the bottom of the fixed plate 21 are limited and abut against each other.

[0038] Preferably, in some embodiments, the gate assembly 25 has two symmetrically arranged at the bottom of the pressing position 212, including a support plate 251 and a fixing block 252 screwed together. The fixing plate 21 has a mounting groove 213, and the fixing block 252 is installed in the mounting groove 213. An elastic element (not shown in the figure) is provided between the support plate 251 and the fixing plate 21 or the fixing block 252. Under the action of the elastic element, the support plate 251 and the fixing plate 21 remain in abutting state without external force, so that when the pressing member 5 falls into the pressing position 212, the support plate 251 can support it. As the pressing head 31 moves down and The support plate 251 is pushed up, causing the elastic element to be in a compressed state. Under the compression of the elastic element, the support plate 251 can rotate downward to avoid the pressing part 5. When the pressing head 31 returns to its original position, the elastic element automatically returns to its original position and extends, pressing the support plate 251 so that it is in contact with the bottom of the fixed plate 21 to achieve a supporting effect. Since elastic elements, such as springs, are prone to wear and rust during long-term use, resulting in a short service life and insufficient elasticity, the pressing effect and efficiency will be affected. Therefore, the reset scheme using the counterweight part 253 does not have the service life defect of the reset scheme using springs, and is a better solution.

[0039] Furthermore, such as Figure 8 As shown, the second feeding mechanism 2 further includes a vibrating feeder 22 and a detection component 23. The detection component 23 has a detection position 2321 corresponding to the discharge end of the vibrating feeder 22. The output end of the detection component 23 corresponds to the receiving position 211. The vibrating feeder 22 is located on the side of the pressing mechanism 3, used to carry the pressed-in part 5 and vibrate it out. The detection component 23 is located on the discharge side of the vibrating feeder 22, and the detection position 2321 corresponds to the discharge end of the vibrating feeder 22, so as to perform timely and rapid detection and improve efficiency. The efficiency of material feeding; the detection component 23 includes an upper slide plate 231, a lower slide plate 232, a lateral drive component 233, and a detection module 234. The detection module 234 is located above the detection position 2321. The lateral drive component 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 arranged sequentially from bottom to top on the connecting rod. The detection module 234 is used to detect whether the press-in part 5 has defects, flaws, or other problems. Specifically, such as Figure 9-10As shown, the detection position 2321 is located on the lower slide plate 232, and the upper slide plate 231 is provided with a "U"-shaped groove 2311 corresponding to the detection position 2321 and with its opening facing the discharge end of the vibrating material tray 22. When the pressing member 5 vibrates and moves out of the vibrating material 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 with the movement of the upper slide plate 231; to avoid When the press-in component 5 moves on the lower slide plate 232, it slides out from the opening side of the "U"-shaped groove 2311. The lower slide plate 232 is provided with an upwardly extending limiting plate 2324 on the side 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, so as to fix the press-in component 5 in the "U"-shaped groove 2311 and improve the conveying efficiency.

[0040] Furthermore, one end of the lower sliding plate 232 is provided with a feeding hole 2322 corresponding to the "U"-shaped groove 2311, and the other end is provided with a waste hole 2323. A waste bin 2325 is also provided below the waste hole 2323. The feeding hole 2322, the "U"-shaped groove 2311, and the waste hole 2323 are arranged alternately. When the press-in part 5 enters the detection position 2321, the detection module 234 performs detection. When the press-in part 5 is determined to be a qualified product, the lateral drive component 233 will drive the upper sliding plate 231 to move towards the receiving position 211. When the U-shaped groove 2311 coincides with the receiving position 211, the press-in part 5 in the U-shaped groove 2311 falls into the receiving position 211. When the detection module 234 detects that the press-in part 5 is a defective product, the transverse drive 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 press-in part 5 in the U-shaped groove 2311 will pass through the waste hole 2323 and fall into the waste box 2325, thereby achieving the screening effect of the press-in part 5.

[0041] Furthermore, such as Figure 11-12As shown, 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 in all directions, facilitating the unobstructed transport of the pressing component 4 to the pressing mechanism 3. The clamping assembly 12 includes a connecting plate 121 and two identical clamping arms 122. The two clamping arms 122 are respectively disposed at both ends of the connecting plate 121 and located 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, each corresponding to one of the two clamping arms 122. The two third driving members 13 are used to control the opening and closing of the two clamping arms 122. In this configuration, the output ends of both third driving components 13 face both 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 pressing component 4, the output axes of the two third driving components 13 push outward, thereby moving the two clamping arms 122 away from each other and placing them in an open state. By moving the robotic arm 11 and rotating the clamping assembly 12, the pressing component 4 is placed between the two clamping arms 122. Then, the output axes of the two third driving components 13 retract inward, causing the two clamping arms 122 to clamp and fix the two ends of the pressing component 4 respectively. Then, the robotic arm 11 is driven to move, thereby achieving the effect of automatically feeding the pressing component 4. The third driving component 13 can be other parts capable of telescopic function, such as cylinders, motors, and lead screws.

[0042] Preferably, the pressing component 4 is provided with a groove 41, and the two clamping arms 122 are provided with a protrusion 1221 on the opposite side of the groove 41. When clamping, the protrusion 1221 is inserted into the groove 41 to limit the pressing component 4, making the clamping force of the two clamping arms 122 more secure. This ensures that the risk of the pressing component 4 falling off due to unstable clamping is reduced during the conveying process. At the same time, it can also make the conveying efficiency of the pressing component 4 higher, thereby improving the overall production efficiency.

[0043] Furthermore, such as Figure 1 , Figure 13As shown, the pressing mechanism 3 also includes a frame 34 and a pressing table 33 placed on the frame 34 and corresponding vertically to the pressing head 31. After the pressing part 4 is transferred, it is placed on the pressing table 33. Since the pressing part 4 has multiple pressing stations 42, the position of the pressing part 4 needs to be constantly adjusted during the pressing process so that each station 42 corresponds to the pressing position 212 and the pressing head 31. Therefore, the bottom of the pressing table 33 is respectively provided with a first moving component 331 that moves along the X-axis and a second moving component 332 that moves along the Y-axis. 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 mounted on the upper surface of the moving plate 36. The first moving component 331 includes a first slide rail 3311, a first slider 3312 and a first driving component 3313. The first slider 3312 is fixedly connected to the lower surface of the moving plate 36. 313 is used to drive the first slider 3312 to slide on the first slide rail 3311, so as to drive the moving plate 36 to move in the X-axis direction, thereby realizing the effect of the second moving component 332 and the pressing component 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 fixedly connected to the moving plate 36, a second slider 3322 and a second driving component 3323. The second slider 3322 is fixedly connected to the lower end face of the pressing table 33. The second driving component 3323 is used to drive the second slider 3322 to slide on the second slide rail 3321, so as to drive the pressing table 33 to move in the Y-axis direction, thereby realizing the effect of the pressing component 4 moving in the X-axis and Y-axis directions so that each station 42 corresponds to the pressing position 212 and performs pressing, without the need for manual adjustment and alignment, saving more time and effort, greatly improving pressing efficiency, and realizing full automation of pressing.

[0044] Preferably, a protective cover 35 is provided above both the first moving component 331 and the second moving component 332. The protective cover 35 can be folded or stretched as it moves, which can prevent dust or debris from falling on the first moving component 331 and the second moving component 332, causing the movement of the pressing component 4 to be stuck or malfunction, thereby affecting the accuracy of pressing.

[0045] The working principle of this invention is explained in detail below: In use, the pressing component 4 is clamped by the clamping assembly 12 and moved to the pressing 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 pressing station 42 on the pressing component 4 can be aligned with the pressing station 212 and wait for pressing. At the same time, the pressing component 5, after being vibrated and discharged from the vibrating material tray 22, will fall onto the detection station 2321 and be detected by the detection module 234. Qualified products are driven by the transverse drive component 233 to move the sliding plate 231 to the receiving station 211, while unqualified products are moved to the waste hole 2323. The pressing component 5 that falls into the receiving station 211 will simultaneously fall into the rotating groove 2412 of the rotating plate 241. Under the action of the rotating drive component 242, the rotating plate 241 carries the pressing component 5 into the rotating groove 2412 of the rotating plate 241. The insert 5 moves along the arc of the slide 26. When the rotating groove 2412 coincides with the pressing position 212, the insert 5 will automatically fall onto the pressing position 212 and be supported by the gate assembly 25. Then, driven by the stamping drive 32, the pressing head 31 moves downward. As the pressing head 31 moves, the insert 5 will automatically adhere to the pressing head 31, while the gate assembly 25 will rotate downward under the push of the pressing head 31 to avoid it, so that the pressing head 31 can carry the insert 5 through the pressing position 212 and press it with the pressing part 4 located below the pressing position 212. After each pressing station 42 is completed, the pressing part 4 will automatically adjust again so that another pressing station 42 corresponds to the pressing position 212 and continues to press, thereby realizing the fully automated pressing of the machine.
