Description

Technical Field

[0001] The present invention relates to the relevant fields of automobile parts production and processing, in particular to an assembly device for a processed engine camshaft cover. Background Art

[0002] The engine camshaft cover is a crucial component on a car engine. It primarily consists of a main cover and a sealing ring, the latter primarily made of an elastic material. The main structure can be found in the Chinese invention patent publication CN214330715U, which discloses a camshaft cover for an automobile engine. The camshaft cover comprises a cover and fixing holes, with fixing holes located at the four corners of the cover's upper end. A sealing ring, fitted with a silicone ring and a raised semicircular shape, is sleeved onto the outer wall of the fixing ring.

[0003] Although the main structure of the engine camshaft cover is disclosed in the prior art, how to automatically and efficiently assemble the main cover body of the camshaft cover with the sealing ring after processing is not disclosed in the prior art. Summary of the Invention

[0004] In order to meet the above-mentioned demand for assembling the engine camshaft cover, the present invention proposes an assembly device for the engine camshaft cover after processing.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0006] An assembly device for a processed engine camshaft cover comprises an assembly table, mounted with a left-hand seat and a cover feeder; a transverse hanger, a sealing ring feeder assembly, and a blocking plate mounted on the left-hand seat; and a lifting control assembly mounted on the transverse hanger, connected to a movable plate, on which an auxiliary support assembly is mounted. The cover feeder supplies the main cover, the sealing ring feeder assembly supplies the sealing ring, and the blocking plate limits the position of the uppermost main cover. The lifting control facilitates subsequent assembly work. The auxiliary support assembly expands the diameter of the sealing ring to facilitate installation.

[0007] As a further improvement to the present invention, the cover feeder comprises a lower base fixedly mounted on the assembly table, a spring mounted on the lower base, an upper push plate connected to the spring, and four guide posts slidably connected to the upper push plate; each guide post is fixedly mounted on the lower base. The four guide posts can be inserted through the four circular holes in the main cover, allowing the main cover to be vertically stacked on the upper push plate and fed upward under the action of elastic force. The distance between the upper end of the guide post and the blocking plate is the thickness of a single main cover.

[0008] As a further improvement of the present invention, the sealing ring supply assembly is composed of a conveyor belt and a limit frame both mounted on the left seat; the front and rear ends of the conveyor belt are both against the limit frame. The conveyor belt and the limit frame can realize stable conveyance and supply of the sealing ring from left to right.

[0009] As a further improvement to the present invention, the upper portion of the limit frame is U-shaped, with a limiter located on the right side of the limit frame. The distance between the limiter and the right end of the conveyor belt is equal to the outer diameter of a single sealing ring, and the distance between the front and rear ends of the limit frame is also equal to the outer diameter of a single sealing ring. This structure ensures that the sealing ring falls stably after being transported to the right and separated from the conveyor belt.

[0010] As a further improvement of the present invention, the lifting control assembly is composed of a hydraulic cylinder and a vertical guide rod both mounted on the transverse suspension bracket; the hydraulic cylinder is connected to the movable plate, and the vertical guide rod is slidably connected to the movable plate. That is, the movable plate can be raised and lowered by the hydraulic cylinder.

[0011] As a further improvement of the present invention, the auxiliary support assembly includes a hollow shaft fixedly mounted on the lower end of the movable plate, a large gear mounted on the hollow shaft via a bearing, a small gear meshing with the large gear, and a motor connected to the small gear; the motor is fixedly mounted on the movable plate. Under the action of the gear transmission, the large gear can be driven to rotate.

[0012] As a further improvement of the present invention, the large gear is provided with four inclined slots distributed along a circular axis. The auxiliary support assembly further includes four auxiliary support rods and circular shafts connected to the auxiliary support rods in a one-to-one manner. The circular shafts are slidably engaged with the corresponding inclined slots. This is a conventional design for a sliding structure, with the auxiliary support rods used to expand the inner diameter of the sealing ring.

[0013] As a further improvement of the present invention, each auxiliary support rod is provided with two transverse clamping portions, the spacing between the two transverse clamping portions being no less than the thickness of the sealing ring, that is, when the auxiliary support rod is in contact with the inner side of the sealing ring, the transverse clamping portions can enable the sealing ring to rise and fall together with the auxiliary support rod.

[0014] As a further improvement to the present invention, the lower end of the movable plate is provided with four radial linear grooves distributed along an annular direction; the upper end of each circular shaft is slidably mounted within a corresponding radial linear groove. The function of this sliding structure is to enable all circular shafts and the auxiliary support rods to move radially when the large gear rotates.

[0015] The beneficial effects of the present invention are:

[0016] 1. The present invention performs directional conveying on the main cover body and the sealing ring to complete automatic supply.

[0017] 2. The present invention can limit the position of the sealing ring, automatically expand its inner diameter, and automatically put the sealing ring onto the outside of the fixed ring to achieve automatic assembly.

[0018] 3. The entire assembly process has a high degree of automation and relatively high assembly efficiency, which is suitable for the implementation of large-scale assembly work. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be explained more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention, not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0031] like Figure 3 As shown, an assembly device for a processed engine camshaft cover is provided with an assembly table 1, on which are mounted a left-hand seat 2 and a cover body feeder; a transverse hanger 7, a sealing ring feeder assembly, and a blocking plate 8; a lifting control assembly is mounted on the transverse hanger 7, which is connected to a movable plate 11, on which an auxiliary support assembly is mounted. The cover body feeder is used to feed the main cover body, the sealing ring feeder assembly is used to feed the sealing ring, and the blocking plate 8 is used to limit the position of the uppermost main cover body. The lifting control is used to facilitate control of subsequent assembly work. The auxiliary support assembly is used to expand the diameter of the sealing ring to facilitate installation.

[0032] like Figure 3 and Figure 4 As shown, the cover feeder consists of a lower base 3 fixedly mounted on the assembly table 1, a spring 4 mounted on the lower base 3, an upper push plate 5 connected to the spring 4, and four guide posts 6 slidably connected to the upper push plate 5; the guide posts 6 are all fixedly mounted on the lower base 3. The four guide posts 6 can be inserted through the four circular holes in the main cover, allowing the main cover to be vertically stacked on the upper push plate 5 and fed upward under the action of the elastic force. The distance between the upper end of the guide post 6 and the blocking plate 8 is the thickness of a single main cover.

[0033] like Figure 5 As shown, the sealing ring supply assembly is composed of a conveyor belt 9 and a limit frame 10, both of which are installed on the left seat 2. The front and rear ends of the conveyor belt 9 are against the limit frame 10. The conveyor belt 9 and the limit frame 10 can realize stable conveyance and supply of the sealing ring from left to right.

[0034] like Figure 5 As shown, the upper portion of the limiting frame 10 is U-shaped, with a limiting portion 10a provided on the right side of the limiting frame 10. The distance between the limiting portion 10a and the right end of the conveyor belt 9 is equal to the outer diameter of a single sealing ring. The distance between the front and rear sides of the limiting frame 10 is also equal to the outer diameter of a single sealing ring. In other words, this structure ensures that the sealing ring falls stably after being transported to the right and separated from the conveyor belt 9.

[0035] like Figure 6 As shown, the lifting control assembly is composed of a hydraulic cylinder 12 and a vertical guide rod 13, both of which are mounted on the horizontal hanger 7; the hydraulic cylinder 12 is connected to the movable plate 11, and the vertical guide rod 13 is slidably connected to the movable plate 11. That is, the movable plate 11 can be raised and lowered by the hydraulic cylinder 12.

[0036] like Figure 6As shown, the auxiliary support assembly includes a hollow shaft 14 fixedly mounted on the lower end of the movable plate 11, a large gear 15 mounted on the hollow shaft 14 through a bearing, a small gear 16 meshing with the large gear 15, and a motor 17 connected to the small gear 16; the motor 17 is fixedly mounted on the movable plate 11. Under the action of the gear transmission, the large gear 15 can be driven to rotate.

[0037] like Figure 6 and Figure 7 As shown, the large gear 15 has four inclined slots 15a distributed along a circular axis. The auxiliary support assembly also includes four auxiliary support rods 18 and circular shafts 19 connected to each of the auxiliary support rods 18. The circular shafts 19 slide in contact with the corresponding inclined slots 15a. This is a conventional design for a sliding structure, with the auxiliary support rods 18 used to expand the inner diameter of the sealing ring.

[0038] like Figure 7 As shown, each auxiliary support rod 18 is provided with two transverse clamping portions 18a. The distance between the two transverse clamping portions 18a is not less than the thickness of the sealing ring. That is, when the auxiliary support rod 18 is in contact with the inner side of the sealing ring, the transverse clamping portions 18a can enable the sealing ring to rise and fall together with the auxiliary support rod 18.

[0039] like Figure 8 As shown, the lower end of the movable plate 11 has four radial linear grooves 11a distributed along an annular direction; the upper end of each circular shaft 19 slides within a corresponding radial linear groove 11a. This sliding structure allows all circular shafts 19 and the auxiliary support rods 18 to move radially when the large gear 15 rotates.

[0040] Before use, the Figure 1 The main covers shown are stacked one by one on the upper push plate 5 by means of the cooperation between the circular holes and the guide pillars 6 , so that the uppermost main cover abuts against the blocking plate 8 .

[0041] When used, the artificial Figure 2 The sealing ring shown is placed on the conveyor belt 9 so that the sealing ring is smoothly conveyed to the right by the conveyor belt 9 and automatically falls onto the fixing ring carried by the main cover after leaving the conveyor belt 9.

[0042] After hydraulic cylinder 12 pushes movable plate 11 downward to a certain height, motor 17 rotates, driving large gear 15 counterclockwise and moving all circular shafts 19 radially outward. This forces auxiliary support rods 18 to contact the inner wall of the sealing ring, thereby expanding the inner sealing ring. Hydraulic cylinder 12 then pushes downward further, causing the lowermost transverse clamping portion 18a to abut the bottom end of the fixed groove and the sealing ring to descend until it abuts the fixed ring. The sealing ring now fits around the outside of the fixed ring, completing assembly. At this point, all auxiliary support rods 18 are controlled to first move radially inward, then upward and reset. The uppermost assembled camshaft cover can then be removed from the right side.

[0043] In the above implementation process, in order to prevent the sealing ring from being unable to be stably mounted on the fixed ring after being separated from the conveyor belt 9 and falling, and thus being tilted, as another improvement of the present invention, Figure 9 As shown, a U-shaped extension portion 10b is provided at the lower right end of the limiting frame 10, which cooperates with the right end of the conveyor belt 9 to limit the falling sealing ring and prevent it from tilting.

[0044] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and description merely illustrate the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
