Description

Technical Field

[0001] The present invention belongs to the field of engine cylinder heads, and particularly relates to a press-fitting device with automatic feeding. Background Art

[0002] With the rapid development of the automotive industry and the continuous increase in people's demand for automobiles, automobile manufacturers need to continuously improve production efficiency to meet market demand. Since the current production of automobiles involves different production workshops manufacturing different components, and then assembly workers assembling the manufactured components together to form a complete automobile production line, to ensure the production efficiency of automobiles, the production efficiency of each component must be guaranteed. Among them, as the heart component of an automobile, the production of the engine is an important link in automobile production. Since current automobile engines are all equipped with cylinder heads, pipes for intake and exhaust are press-fitted on the top surface of the cylinder head, and seat rings are press-fitted at an angle on the inner surface of the engine cylinder head corresponding to the positions of the intake pipe and the exhaust pipe. However, in the prior art, most of the seat ring press-fitting is carried out manually. Although it can complete the press-fitting of the seat ring, its press-fitting efficiency and press-fitting accuracy are both low, and it is also easy to damage the seat ring. Summary of the Invention

A feeding part and an installation frame are arranged on one side of the base. The top of the installation frame extends towards the assembly table and is equipped with a stamping driving part. The output end of the stamping driving part extends downward and is connected with a stamping head. The stamping head is provided with an adsorption part for adsorbing the seat ring. A clamping mechanism is arranged on one side of the installation frame. A screening mechanism is arranged between the clamping mechanism and the feeding part. The clamping mechanism includes a first slide plate, a first sliding piece and a rotation driving part. A docking position is arranged on one side of the first slide plate, and a press-fitting hole is arranged on the other side. The docking position is docked with the screening mechanism. The press-fitting hole is located directly below the stamping head. An elastic gate is arranged at the bottom of the press-fitting hole for elastically supporting the seat ring in the press-fitting hole. A material receiving hole is arranged at one end of the first sliding piece, and a rotation center is arranged at the other end. The rotation center is rotatably connected to the middle part between the docking position and the press-fitting hole of the first slide plate. The output shaft of the rotation driving part is connected with the rotation center.

[0007] Preferably, the elastic gate includes a rotating seat and a support member symmetrically arranged on both sides of the bottom of the press-fitting hole. The two support members cooperate to support the seat ring. One side of the support member is rotatably connected to the rotating seat. The distance between the widest parts of the two support members is less than the diameter of the press-fitting hole. The support member extends with a reset member on the side away from the press-fitting hole.

[0008] Preferably, the two reset members extend obliquely in opposite directions and form an angle α with the bottom surface of the first slide plate. The reset member is in limit fit with the bottom surface of the first slide plate.

[0009] Preferably, a counterweight portion is provided at one end of the reset member away from the support member.

[0010] Preferably, an arc-shaped slideway is provided on the first slide plate. The surface of the slideway is a smooth surface. The docking position is arranged at one end of the slideway close to the screening mechanism. The press-fitting hole penetrates upwardly at the other end of the slideway. The rotation center of the first sliding piece coincides with the center of the slideway.

[0011] Preferably, two limiting rods are provided on the top surface of the first slide plate. One of the limiting rods is arranged between the rotation center and the docking position, and the other limiting rod is arranged between the rotation center and the press-fitting hole. The two limiting rods are respectively used to abut against both sides of the first sliding piece.

[0012] Preferably, the first sliding piece extends from the rotation center in a direction away from the material receiving hole and is provided with a balance block. The length from the rotation center to the material receiving hole is greater than the length from the rotation center to the balance block.

[0013] Preferably, the screening mechanism includes a detection module, a second slide plate, a second sliding piece and a horizontal driving member. The second slide plate is provided with a discharge hole at a position above the docking position and is used to dock with the docking position. A material receiving position for docking with the feeding part is provided in the middle of the second slide plate. A waste hole is provided at one end of the second slide plate away from the discharge hole. The bottom of the waste hole is connected to a waste box. The detection module is arranged above the material receiving position. A material receiving groove opening towards the feeding part is provided on one side of the second sliding piece.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] During use, the seat ring enters the screening mechanism through the feeding part. At the same time, the rotating driving part drives one end of the first sliding piece provided with the material receiving hole to swing to the docking position of the first sliding plate. After being screened by the screening mechanism, the seat ring falls into the material receiving hole of the first sliding piece, and then the rotating driving part drives the first sliding piece to move the seat ring into the pressing hole. At this time, the seat ring is elastically supported by the elastic gate in the pressing hole, preventing the seat ring from directly falling when entering the pressing hole. After the assembly table drives the assembly position of the cylinder head to move directly below the pressing hole, the stamping driving part drives the stamping head to move downward. During this process, the adsorption part of the stamping head adsorbs and fixes the seat ring, and pushes open the elastic gate as the stamping head descends. The stamping head drives the seat ring to descend and press-fits the seat ring onto the installation position of the cylinder head, realizing automatic screening and installation of the seat ring, with relatively high production efficiency.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0033] As Figures 1 to 12 shown, the present invention provides a press - fitting device for automatic feeding, which is used to install the seat ring 10 on the mounting position 30 of the cylinder head 20, including a base 1 and an assembly table 2 arranged on the top of the base 1. A feeding part 11 and a mounting frame 12 are arranged on one side of the base 1. The top of the mounting frame 12 extends towards the assembly table 2 and is provided with a stamping driving part 13. The output end of the stamping driving part 13 extends downward and is connected with a stamping head 131. The stamping head 131 is provided with an adsorption part for adsorbing the seat ring 10. A material clamping mechanism 3 is arranged on one side of the mounting frame 12. A screening mechanism 4 is arranged between the material clamping mechanism 3 and the feeding part 11. The material clamping mechanism 3 includes a first slide plate 31, a first sliding piece 32 and a rotation driving part 33. A docking position 311 is arranged on one side of the first slide plate 31, and a press - fitting hole 312 is arranged on the other side. The docking position 311 is docked with the screening mechanism 4. The press - fitting hole 312 is located directly below the stamping head 131. An elastic gate 34 is arranged at the bottom of the press - fitting hole 312 for elastically supporting the seat ring 10 in the press - fitting hole 312. One end of the first sliding piece 32 is provided with a material receiving hole 321, and the other end is provided with a rotation center 322. The rotation center 322 is rotatably connected to the middle part between the docking position 311 and the press - fitting hole 312 of the first slide plate 31. The output shaft of the rotation driving part 33 is connected with the rotation center 322.

[0034] Furthermore, asFigures 5 to 8 , the elastic gate 34 includes a rotating seat 341 and a support member 342 symmetrically arranged on both sides of the bottom of the press-fitting hole 312. The two support members 342 cooperate to support the seat ring 10. One side of the support member 342 is rotatably connected to the rotating seat 341. The distance between the two widest parts of the two support members 342 is smaller than the diameter of the press-fitting hole 312. The support member 342 extends a reset member 343 on the side away from the press-fitting hole 312. The two reset members 343 extend obliquely in opposite directions and form an angle α with the bottom surface of the first slide plate 31. The reset member 343 is in limit cooperation with the bottom surface of the first slide plate 31. The reset member 343 is provided with a counterweight portion 344 at the end away from the support member 342. Specifically, after the seat ring 10 enters the material receiving hole 321, the first slide piece 32 is rotated by the rotation driving member 33 to swing the material receiving hole 321 to the press-fitting hole 312 along the rotation center 322 and drop into the press-fitting hole 312, so that the bottom of the seat ring 10 is supported by the elastic gate 34, that is, the bottom of the seat ring 10 is supported by the support member 342 and stays in the press-fitting hole 312. At this time, the sum of the weight of the seat ring 10 and the weight of the support member 342 is less than the weight of the counterweight portion 344, so that the counterweight portion 344 always presses the support member 342 against the bottom surface of the first slide plate 31, thereby realizing the supporting effect on the seat ring 10; Figure 8 In the process of changing from 8A to 8B in, when the stamping driving member 13 drives the stamping head 131 to move towards the press-fitting hole 312, after the stamping head 131 adsorbs the seat ring 10, the stamping head 131 continues to descend to push the support member 342 to both sides, thereby driving the reset member 343 to swing along the rotating seat 341 towards the direction close to the bottom surface of the first slide plate 31, and the angle α gradually decreases during this process; Figure 8During the process of changing from 8B to 8A, after the press-fitting is completed, the punch 131 is driven by the punching driving member 13 to move upward, gradually passing through the press-fitting hole 312 and rising. During this process, the reset member 343 swings along the rotating seat 341 away from the bottom surface of the first slide plate 31 due to the weight of the counterweight portion 344, and the included angle α gradually expands during this process until the top surface of the support member 342 abuts against the bottom surface of the first slide plate 31 and stops, achieving the reset effect; in some other embodiments, the reset member 343 includes a main body and a spring, wherein the main body forms an included angle α with the bottom surface of the first slide plate 31, one end of the spring is connected to the surface of the main body close to the first slide plate 31, and the other end of the spring is connected to the first slide plate 31. When in use, the punch 131 pushes the support member 342 to rotate and swing along the rotating seat 341, so that the main body swings along the rotating seat 341 towards the direction close to the first slide plate 31 and compresses the spring. When resetting, the spring stretches to push the main body to swing along the rotating seat 341 away from the bottom surface of the first slide plate 31 until the support member 342 abuts against the bottom surface of the first slide plate 31 and stops; however, compared with some solutions using the counterweight portion 344 to achieve reset, the solution using a spring requires setting an installation position 30 for the spring on the bottom surface of the first slide plate 31, and also requires leaving a space for accommodating the spring. Moreover, the elasticity of the spring is easily weakened after long-term and multiple operations, resulting in the support member 342 being unable to closely fit the bottom surface of the first slide plate 31, and the seat ring 10 is prone to angular inclination after entering the press-fitting hole 312, affecting the adsorption effect of the punch 131 on the seat ring 10 and thus affecting the installation effect; the reset solution using the counterweight portion 344 does not have the defect of the service life of the reset solution using a spring and is a better solution.

[0035] Furthermore, as Figures 3 to 4 , an arc-shaped slideway 313 is provided on the first slide plate 31, the docking position 311 is arranged at one end of the slideway 313 close to the screening mechanism 4, the press-fitting hole 312 penetrates upwardly through the other end of the slideway 313, and the rotation center 322 of the first sliding piece 32 coincides with the center of the slideway 313. Specifically, when the seat ring 10 enters the material receiving hole 321 through the screening mechanism 4, the first sliding piece 32 is driven by the rotation driving member 33 to rotate along the rotation center 322, so that the material receiving hole 321 slides in the slideway 313. The surface of the slideway 313 can be set as a smooth surface. When the seat ring 10 falls into the material receiving hole 321 and slides on the slideway 313, the friction between the seat ring 10 and the slideway 313 is reduced.

[0036] Furthermore, as Figures 3 to 4, two limiting rods 314 are provided on the top surface of the first slide plate 31. The two limiting rods 314 are respectively arranged on both sides of the rotation center 322 of the first sliding piece 32, and the two limiting rods 314 are respectively used for abutting against both sides of the first sliding piece 32. The first sliding piece 32 extends from the rotation center 322 in a direction away from the material receiving hole 321 and is provided with a balance block 323. The length from the rotation center 322 to the material receiving hole 321 is greater than the length from the rotation center 322 to the balance block 323. Specifically, when the rotation driving member 33 drives the first sliding piece 32 to rotate along the rotation center 322 and moves the material receiving hole 321 along the slideway 313 to the docking position 311, the limiting rod 314 between the rotation center 322 and the docking position 311 abuts against one side of the first sliding piece 32 to stop the swinging of the first sliding piece 32, so that the first sliding piece 32 drives the material receiving hole 321 to accurately reach the docking position 311, realizing an accurate docking effect. After the seat ring 10 enters the material receiving hole 321, the rotation driving member 33 drives the first sliding piece 32 to rotate along the rotation center 322, and moves the material receiving hole 321 along the slideway 313 to above the press-fitting hole 312. The limiting rod 314 between the rotation center 322 and the press-fitting hole 312 abuts against the other side of the first sliding piece 32 to stop the swinging of the first sliding piece 32, so that the first sliding piece 32 drives the material receiving hole 321 to accurately dock with the press-fitting hole 312, and the seat ring 10 in the material receiving hole 321 accurately falls into the press-fitting hole 312. At the same time, during the process of the rotation driving member 33 driving the first sliding piece 32 to rotate and swing along the rotation center 322, due to the longer lever arm from the rotation center 322 to the material receiving hole 321, a greater centrifugal force will act on the material receiving hole 321 at the end of the first sliding piece 32 during the rotation process, and the influence of the centrifugal force will be amplified after the seat ring 10 falls into the material receiving hole 321, resulting in deformation and dislocation of the first sliding piece 32. Eventually, the seat ring 10 passing through the screening mechanism 4 cannot enter the material receiving hole 321 and the seat ring 10 in the material receiving hole 321 cannot enter the press-fitting hole 312, leading to equipment failure. By setting the balance block 323, the centrifugal force generated at the material receiving hole 321 at the end of the first sliding piece 32 during the rotation process can be balanced, avoiding the deformation and dislocation of the first sliding piece 32 and achieving a more accurate moving effect.

[0037] Further, as Figures 9 to 10, the screening mechanism 4 includes a detection module 41, a second slide plate 42, a second sliding piece 43 and a horizontal driving member 44. The second slide plate 42 is provided with a discharge hole 421 at a position above the docking position 311 and is used to dock with the docking position 311. A material receiving position 422 for docking with the feeding part 11 is provided in the middle of the second slide plate 42. A waste hole 423 is provided at one end of the second slide plate 42 away from the discharge hole 421. A waste box 424 is connected to the bottom of the waste hole 423. The detection module 41 is arranged above the material receiving position 422. A material receiving groove 431 opening towards the feeding part 11 is provided on one side of the second sliding piece 43. The horizontal driving member 44 is used to drive the second sliding piece 43 to slide on the top surface of the second slide plate 42. The detection module 41 is arranged above the material receiving position 422. The detection module 41 includes a connecting rod 411 and a supplementary light lamp 412 and a CCD camera 413 sequentially arranged on the connecting rod 411 from bottom to top. A limiting plate 441 is provided on one side of the second slide plate 42 close to the feeding part 11. The limiting plate 441 opens towards the feeding part 11 at the corresponding position of the material receiving position 422. Specifically, the horizontal driving member 44 drives the second sliding piece 43 to slide on the second slide plate 42, so that the material receiving groove 431 on the second sliding piece 43 reaches the material receiving position 422 of the second slide plate 42, and the material receiving groove 431 is docked with the feeding part 11. The seat ring 10 enters the screening mechanism 4 through the feeding part 11. The feeding part 11 can be a vibrating disk. The vibrating disk vibrates to make the seat ring 10 enter the material receiving groove 431. After being detected by the CCD camera 413, when the seat ring 10 is detected as NG, the horizontal driving member 44 drives the second sliding piece 43 to slide towards the waste hole 423. Finally, the material receiving groove 431 is docked with the waste hole 423 to make the NG seat ring 10 fall into the waste box 424. The second sliding piece 43 moves towards the material receiving position 422 again, so that the material receiving groove 431 reaches the material receiving position 422 to receive materials. When the seat ring 10 enters the material receiving groove 431 and the seat ring 10 is detected as a qualified seat ring 10, the horizontal driving member 44 drives the second sliding piece 43 to move towards the discharge hole 421. During this process, the first sliding piece 32 is driven by the rotation driving member 33 to rotate and swing, so that the material receiving hole 321 reaches the docking position 311 and the material receiving hole 321 is directly below the discharge hole 421. When the second sliding piece 43 drives the material receiving groove 431 to be directly above the discharge hole 421 and stops, the seat ring 10 passes through the discharge hole 421 and enters the material receiving hole 321 to achieve the screening effect. On this basis, by providing a limiting plate 441 on one side of the second slide plate 42 close to the feeding part 11 except for the material receiving position 422, the seat ring 10 can enter the material receiving groove 431 through the notch of the material receiving position 422. During the sliding process of the second sliding piece 43, a sealed frame is formed between the material receiving groove 431 and the limiting plate 441 to prevent the seat ring 10 from falling onto the assembly table 2 during the sliding process and achieve a good transportation effect.

[0038] The innovation of the present invention lies in:

[0039] During use, the seat ring 10 enters the screening mechanism 4 through the feeding part 11. At the same time, the rotating drive member 33 drives one end of the first sliding piece 32 provided with the material receiving hole 321 to swing to the docking position 311 of the first sliding plate 31. After being screened by the screening mechanism 4, the seat ring 10 drops into the material receiving hole 321 of the first sliding piece 32. Then, the rotating drive member 33 drives the first sliding piece 32 to move the seat ring 10 into the press-fitting hole 312. At this time, the seat ring 10 is elastically supported by the elastic gate 34 in the press-fitting hole 312, preventing the seat ring 10 from directly dropping when entering the press-fitting hole 312. After the assembly table 2 drives the assembly position of the cylinder head 20 to move to directly below the press-fitting hole 312, the stamping drive member 13 drives the stamping head 131 to move downward. During this process, the adsorption part of the stamping head 131 adsorbs and fixes the seat ring 10, and pushes open the elastic gate 34 as the stamping head 131 descends. The stamping head 131 drives the seat ring 10 to descend and press-fits the seat ring 10 onto the installation position 30 of the cylinder head 20, realizing automatic screening and installation of the seat ring 10, with relatively high production efficiency.
