Description

Technical Field

[0001] The present application relates to the technical field of engine cylinder head assembly, and in particular to an engine cylinder head assembly device used in automobile engine manufacturing. Background Art

[0002] The automobile engine is an important power component in the automobile, which mainly provides driving power for the operation of the automobile. A piston that can move back and forth is installed inside the engine. The reciprocating movement of the piston can control the rotation of the crankshaft, output mechanical energy, further control the rotation of the corresponding connected wheel set and transmit power to the main shaft of the tire, which can further drive the movement of the automobile.

[0003] The interior of an automobile engine mainly includes a crankshaft, an engine block, and an automobile cylinder head, which are key components. The engine cylinder head mainly serves to seal the interior of the engine. During the installation of the automobile engine, the worker needs to first fix the engine on the outside of the mounting base, and then use a fixing fixture to clamp and fix the cylinder head. After moving the cylinder head to the outside of the engine, the cylinder head can be positioned and installed through a positioning assembly. At this time, the worker places a gasket on the outside of the cylinder head, and then places multiple sets of fixing screws into the fixing holes in sequence. The fixing screws can be pre-tightened using a tightening device. When fixing the cylinder head, the worker performs continuous operation processing, and multiple sets of fixing screws will be moved and placed at the same time during use. Since there is no structure for monitoring and warning the placement of fixing screws, workers are prone to forget to place a screw due to negligence or inattention during continuous operations, and are also prone to placing the screw in the wrong position. For this reason, we propose an engine cylinder head assembly device for automobile engine manufacturing. Summary of the invention

At this time, the rotation of the control rod 8 can drive the fixing screw 16 to rotate, and the fixing screw 16 can be pre-tightened. A baffle that limits the control rod 8 from removing the fixing tube 7 is provided inside the fixing tube 7, which can prevent the control rod 8 from being out of contact with the inside of the fixing tube 7.

[0035] See also Figure 3 , Figure 4A connecting component 9 is installed inside the fixing cylinder 7, a contact 10 is installed outside the connecting component 9, a mounting plate 11 is installed outside the supporting plate 5, a contact 2 12 is installed outside the mounting plate 11, and the contact 1 10 and the contact 2 12 can be controlled to be electrically connected through the connecting component 9.

A controller 13 is installed outside the supporting plate 5, and an indicator light is arranged inside the controller 13. When the contact 10 and the contact 2 12 are connected, the indicator light on the controller 13 can light up, which is for monitoring when the fixing screw 16 is fixed.

[0036] See also Figure 4 , Figure 5 , Figure 6 The connecting assembly 9 includes a tooth plate 1 901 and a tooth plate 2 902. The outer surfaces of the tooth plates 1 901 and the tooth plates 2 902 are slidably connected to the interior of the fixed tube 7. A plurality of connecting balls 903 are installed inside the tooth plate 1 901. The outer surfaces of the connecting balls 903 are in contact with the outer surface of the control rod 8. A plurality of connecting gears 904 are installed inside the fixed tube 7. The teeth of the connecting gears 904 are meshed with the teeth of the tooth plates 1 901 and the tooth plates 2 902. When the clamp plate 6 is fixed with the fixing screws 16, the control rod 8 will move up. At this time, the horizontal plate above the control rod 8 will push the tooth plate 1 901 to move through the connecting balls 903. Under the connection and rotation of the connecting gear 904, the tooth plate 1 901 and the tooth plate 2 902 will move in the opposite direction. When the tooth plate 1 901 moves up, the tooth plate 2 902 will move down. The connecting balls 903 can assist the rotation of the control rod 8, thereby ensuring the stability of the control rod 8 during rotation.

[0037] The outer surfaces of tooth plate 1 901 and tooth plate 2 902 are fixedly installed with movable plates 905, and the interior of the fixed cylinder 7 is slidably connected with a connecting rod 906. The outer surface of the connecting rod 906 is slidably connected to the interior of the movable plate 905. The base of contact 10 is fixedly installed on the outside of a group of movable plates 905. The contacts of contact 10 and contact 2 12 are electrically connected to each other. The outside of the connecting rod 906 is covered with a spring 2 907, one end of the spring 2 907 is fixedly installed on the inner wall of the fixed cylinder 7, and the other end of the spring 2 907 is fixedly installed on the outer surface of the movable plate 905. The spring 2 907 can be used to control the relative reset of tooth plate 1 901 and tooth plate 2 902. When the fixing screw 16 is clamped and fixed, the spring 2 907 is compressed. When the fixing screw 16 is released, the spring 2 907 rebounds to push the tooth plate 1 901 to reset.

[0038] See also Figure 6The outer surface of the fixing cylinder 7 is fixedly installed with a mounting cylinder 19, and a pre-tightening device 20 is installed inside the mounting cylinder 19. A rotating frame 21 is fixedly installed on the output end of the pre-tightening device 20, and the rotating frame 21 can be controlled to rotate through the pre-tightening device 20. The interior of the pre-tightening device 20 is mainly composed of a rotating motor and an output shaft, wherein one end of the output shaft is connected to the outer surface of the rotating frame 21, and a rotating rod 22 is fixedly installed on the outer surface of the control rod 8. The cross-section of the rotating rod 22 is a hexagonal structure, and the outer surface of the rotating rod 22 is slidably connected to the interior of the rotating frame 21. When the fixing screw 16 is clamped and fixed by the clamping plate 6, the rotating rod 22 can be pushed to move. At this time, the rotating rod 22 will enter the interior of the rotating frame 21. When the rotating frame 21 rotates, the rotating rod 22 can be controlled to rotate, and the fixing screw 16 can be rotated and pre-tightened. When the fixing screw 16 is pre-tightened, it will slowly move down. At this time, the rotating rod 22 will gradually be disconnected from the rotating frame 21 to prevent the pre-tightening force from being too large, which is convenient for subsequent staff to move and inspect.

[0039] See also Figure 8 , a mounting frame 23 is fixedly installed on the outer surface of the fixing frame 1, and the position of the mounting frame 23 corresponds to the position of the mounting base 31 and the engine and is arranged up and down. A limit plate 24 is fixedly installed on the outer surface of the mounting frame 23, and a connecting frame 25 is slidably connected to the outer surface of the limit plate 24. Under the limit control of the limit plate 24, the connecting frame 25 can move up and down outside the mounting frame 23. A lifting device 26 is installed on the outside of the mounting frame 23. The output end of the internal fixing rope of the lifting device 26 is fixedly installed on the outer surface of the connecting frame 25. A connecting groove 27 is provided inside the connecting frame 25. The outer surface of the support plate 5 is slidably connected to the inside of the connecting groove 27. When the support plate 5 clamps the fixing screw 16, it is disengaged from the inside of the connecting groove 27. At this time, the support plate 5 can move up and down alone. The connecting frame 25 can be fixed in one position under the action of the lifting device 26. After the fixing screw 16 is fixed, the support plate 5 and the connecting groove 27 can be combined into a whole after being connected. Under the control of the lifting device 14 and the lifting device 26, the two can move synchronously.

[0040] A connecting rope 28 is fixedly installed on the lower surface of the connecting frame 25, and a pad 29 is fixedly installed on the other end of the connecting rope 28. The outer surface of the limit plate 24 is slidably connected to the inside of the pad 29. Under the action of the connecting rope 28, the pad 29 can move with the connecting frame 25. When the support plate 5 is connected to the connecting frame 25, it will move downward. At this time, the pad 29 will first be connected to the cylinder head of the engine, and then the connecting frame 25 and the support plate 5 will move again and contact with the pad 29. At this time, the fixing screw 16 can enter the hole inside the pad 29 and enter the fixing hole of the cylinder head. After the pre-tightening is completed, the connecting frame 25 and the support plate 5 are reset up and down. Under the action of the connecting rope 28, the pad 29 will also be out of contact with the cylinder head, and the staff does not need to manually remove the pad 29 after the pre-tightening is completed.

[0041] The implementation principle of the engine cylinder head assembly device used in automobile engine manufacturing in the embodiment of the present application is as follows: when in use, the driving motor 204 controls the threaded rod 202 to rotate, so as to move the support plate 5 to the position of the fixing screw 16, and then the support plate 5 can be controlled to move under the action of the lifting device 4;

[0042] When the support plate 5 moves, the clamping plate 6 will contact one end of the fixing screw 16, and the clamping plate 6 will move elastically under the elastic push of the spring 18. At this time, the fixing screw 16 can be clamped in the middle position of the two groups of clamping plates 6, and the fixing screw 16 can be clamped and taken. When the fixing screw 16 is fixed in the position of the clamping plate 6, it will push the tooth plate 1 901 to move. At this time, the tooth plate 1 901 drives the tooth plate 2 902 to move by meshing with the connecting gear 904. The tooth plate 2 902 controls the electrical connection between the contact 1 10 and the contact 2 12. The indicator light on the controller 13 can detect the number of fixed fixing screws 16. When the number of fixing screws 16 is insufficient, an alarm sound will be issued to the outside.

[0043] After the fixing screws 16 are clamped and fixed, the rotating rod 22 will enter the interior of the rotating frame 21. At this time, the support plate 5 is controlled to move to the interior of the connecting groove 27. The support plate 5 and the connecting frame 25 can move synchronously. The support plate 5 and the connecting frame 25 can be controlled to move downward through the cooperation of the lifter 1 4 and the lifter 2 26. Under the action of the connecting rope 28, the pad 29 will move downward to the upper end of the cylinder head and contact the cylinder head. Then, after the support plate 5 and the connecting frame 25 move again, the support plate 5 can contact the pad 29.

[0044] The rotating frame 21 can be controlled to rotate by the pre-tightening device 20, and the rotating rod 22 and the control rod 8 can be further driven to rotate, so that the fixing screw 16 can be rotated and pre-tightened. When the fixing screw 16 is pre-tightened, it will gradually move downward and break away from the clamping plate 6, and the fixing screw 16 can be pre-tightened at this time;

[0045] After the pre-tightening is completed, the support plate 5 and the connecting frame 25 are reset by controlling the puller 1 4 and the puller 2 26. Under the action of the connecting rope 28, the pad 29 can be driven to be out of contact with the cylinder head, and the staff does not need to manually pick it up again.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
