Detailed implementation mode

[0027] The core of the present utility model is to provide a tightening device for the spark plug bushing of the cylinder head to reduce the labor intensity of workers when tightening the spark plug bushing of the cylinder head.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and implementation modes.

[0029] Please refer to Figure 1 and Figure 2 .

[0030] In a specific implementation mode, the tightening device for the spark plug bushing of the cylinder head provided by the specific embodiment of the present utility model includes a conveyor device 1, a positioning device 5, a compression device 2 and a tightening machine 3. The conveyor device 1 is used to convey the spark plug bushing of the cylinder head. The conveyor device 1 can be chain drive or belt drive. In order to facilitate the support of the spark plug bushing of the cylinder head, a support member is provided below the position on the conveyor device 1 that supports the spark plug bushing of the cylinder head, and the conveyor device 1 and the support member can be slidably connected.

[0031] The positioning device 5 is used to limit the spark plug bushing of the cylinder head to a preset position on the conveyor device 1. Specifically, the positioning device 5 can be a clamping block. The two clamping blocks are respectively located on the left and right sides of the moving direction of the conveyor device 1 and can move horizontally. The spark plug bushing of the cylinder head is clamped by the clamping blocks approaching each other. When moving away from each other, the spark plug bushing of the cylinder head is arranged separately from the clamping blocks. The movement of the clamping blocks can be realized by structures such as cylinders or telescopic cylinders.

[0032] The compression device 2 is located above the conveyor device 1, and the compression device 2 is used to compress the spark plug bushing of the cylinder head. In one implementation mode, the compression device 2 can be driven by a linear motor to lift and compress the spark plug bushing of the cylinder head.

[0033] In another implementation mode, the compression device 2 includes a lifting module 21 and a pressing-down module 22 installed at the bottom end of the telescopic device of the lifting module 21. The tightening machine 3 is installed on the pressing-down module 22. Specifically, the lifting module 21 can be a telescopic cylinder or a telescopic rod.

[0034] The tightening machine 3 is an electric control device. The tightening machine 3 is located above the conveying device 1. The tightening machine 3 is used to tighten the spark plug bushing of the cylinder head so that the spark plug bushing of the cylinder head is within a preset torque range. That is, the tightening machine 3 stops tightening after reaching the standard torque. The lifting of the tightening machine 3 can be achieved by a linear motor, a telescopic cylinder or a telescopic cylinder, etc. After the tightening work is completed, the tightening machine 3 rises away from the spark plug bushing of the cylinder head. When it is necessary to tighten the spark plug bushing of the cylinder head, the tightening machine 3 descends to cooperate with the spark plug bushing of the cylinder head. The tightening machine 3 completes the automatic tightening action of the spark plug bushing of the cylinder head through a relay combination circuit.

[0035] When it is necessary to tighten the spark plug bushing of the cylinder head, first, the conveying device 1 drives the spark plug bushing of the cylinder head to move forward. When the spark plug bushing of the cylinder head moves to a preset position, the conveying device 1 stops working. Then, the spark plug bushing of the cylinder head is limited to the preset position by the fixing device 5. Then, the spark plug bushing of the cylinder head is pressed by the pressing device 2. The tightening machine 3 tightens the spark plug bushing of the cylinder head within a preset torque range. After the tightening work of the tightening machine 3 is completed, the tightening machine 3, the pressing device 2 and the positioning device 5 return to their original positions, and the conveying device 1 continues to work to output the tightened spark plug bushing of the cylinder head.

[0036] From the above description, it can be seen that in the spark plug bushing tightening device provided in the specific embodiment of the present application, the spark plug bushing of the cylinder head is conveyed to a preset position by the conveying device 1, the spark plug bushing of the cylinder head is limited by the positioning device 5, the spark plug bushing of the cylinder head is pressed by the pressing device 2, and the spark plug bushing of the cylinder head is tightened by the tightening machine 3. And since the tightening machine 3 is an electric control device, there is no need for staff to manually tighten the spark plug bushing of the cylinder head. Therefore, the spark plug bushing tightening device provided in the present application effectively reduces the labor intensity of the staff in tightening the spark plug bushing of the cylinder head.

[0037] In a specific embodiment, the tightening machine 3 is installed at the bottom end of the pressing device 2 so that when the pressing device 2 presses the spark plug bushing of the cylinder head, the bottom end of the tightening machine 3 presses the spark plug bushing of the cylinder head. At this time, the lifting of the pressing device 2 drives the lifting of the tightening machine 3, and the pressing device 2 cooperates with the spark plug bushing of the cylinder head through the tightening machine 3 to realize the pressing of the spark plug bushing of the cylinder head. That is, the overall synchronous lifting of the tightening machine 3 and the pressing device 2 is realized through a set of lifting equipment.

[0038] In order to facilitate the positioning of the spark plug bushing of the cylinder head, preferably, the spark plug bushing tightening device of the cylinder head is provided with a shielding device 4 and a side clamping device 6. The shielding device 4 is provided with a shielding surface that abuts against one side of the spark plug bushing of the cylinder head. The side clamping device includes a telescopic cylinder and a baffle plate installed at the telescopic end of the telescopic cylinder. Specifically, the telescopic cylinder can be a cylinder or a hydraulic cylinder, etc.

[0039] During specific installation, preferably, the side clamping device 6 is installed above the conveying device 1. Specifically, the housing of the side clamping device 6 is locked above the housing of the conveying device 1 through fasteners.

[0040] When the telescopic cylinder extends, the baffle abuts against the other side of the cylinder head spark plug bushing, and the baffle and the shielding surface clamp the left and right sides of the cylinder head spark plug bushing. Specifically, when the telescopic cylinder retracts, the baffle is separated from the cylinder head spark plug bushing, and the cylinder head spark plug bushing continues to move forward.

[0041] To facilitate clamping of the cylinder head spark plug bushing, preferably, the mating surfaces of the shielding surface and the baffle with the cylinder head spark plug bushing are located on the contour adaptation and limiting surface of the cylinder head spark plug bushing.

[0042] In a specific embodiment, the conveying device 1 is a roller conveyor 1. A gap may be provided between two adjacent rollers in the roller conveyor 1.

[0043] In another embodiment, the sheet material driving device is located above the conveying device 1, and the sheet material driving device drives the baffle to move up and down. Specifically, when the sheet material driving device drives the baffle to descend a preset distance, the baffle can just block the passage of the cylinder head spark plug bushing, and at this time, the baffle is in the closed position. When the sheet material driving device drives the baffle to ascend a preset distance, the distance between the bottom end of the baffle and the conveying device 1 is greater than the thickness of the cylinder head spark plug bushing, and the cylinder head spark plug bushing can pass through the bottom end of the baffle, and at this time, the baffle is in the open position.

[0044] In a specific embodiment, the cylinder head spark plug bushing tightening device further includes a signal sensing module and a control module. The signal sensing module, the positioning device 5, the conveying device 1, the pressing device 2, the tightening machine 3, and the side clamping device 6 are all signal-connected to the control module. The signal sensing module is located at a preset position of the conveying device 1. When the control module receives the signal change transmitted by the signal sensing module when the cylinder head spark plug bushing moves to the signal sensing module, it controls the telescopic cylinder to extend, and the baffle abuts against the other side of the cylinder head spark plug bushing. The positioning device 5 positions the cylinder head spark plug bushing at the preset position of the conveying device 1, the pressing device 2 presses the cylinder head spark plug bushing, and the tightening machine 3 tightens the cylinder head spark plug bushing. Specifically, the signal sensing module can be a photosensitive module. When the cylinder head spark plug bushing moves to the preset position, the photosensitive module is blocked by the cylinder head spark plug bushing, and the control module senses the signal change of the signal sensing module.

[0045] In one embodiment, two positioning devices 5 are used to respectively limit the left and right sides of the cylinder head spark plug bushing.

[0046] As Figure 1As shown, in another embodiment, two positioning devices 5 are used to limit the front and rear sides of the spark plug bushing of the cylinder head respectively. The two positioning devices 5 are the positioning device 5a and the positioning device 5b respectively. At this time, the two positioning devices 5 clamp the front and rear positions of the spark plug bushing of the cylinder head.

[0047] Specifically, the positioning device 5 includes a clamping arm 52 and a lifting device 51 that drives the clamping arm 52 to lift and lower. When the clamping arm 52 descends, it just clamps the side wall of the spark plug bushing of the cylinder head, thereby limiting the spark plug bushing of the cylinder head.

[0048] In order to reduce the lifting equipment, the positioning device 5 is installed at the bottom end of the lifting end of the pressing device 2, and the pressing device 2 drives the positioning device 5 to lift and lower.

[0049] In a specific working mode, when the control module senses the signal change of the signal sensing module, it simultaneously controls the conveying device 1 to stop working. Then it controls the positioning device 5 to limit and clamp the front and rear sides of the spark plug bushing of the cylinder head. The telescopic cylinder extends, and the shielding surface and the baffle clamp the left and right sides of the spark plug bushing of the cylinder head. Then it controls the pressing device 2 to descend and press the spark plug bushing of the cylinder head. The control module controls the tightening device to perform the tightening work. When the tightening machine 3 reaches the standard torque, it stops tightening. Among them, when the control module receives the signal that the tightening machine 3 reaches the standard torque, it controls the positioning device 5, the pressing device 2, the tightening machine 3 and the telescopic cylinder to retract and reset. Specifically, the tightening machine 3 and the pressing device 2 rise, the positioning device 5 moves away from the spark plug bushing of the cylinder head, and then it controls the conveying device 1 to continue working, and outputs the tightened spark plug bushing of the cylinder head into the next working station. Specifically, the control module uses electrical signals to transmit information.

[0050] Preferably, there are two positioning devices 5, and the positioning device 5 is used to limit the opposite sides of the spark plug bushing of the cylinder head. Of course, at least three positioning devices 5 can also be provided, and the positioning devices 5 are evenly distributed along the outer circumference of the cylinder head.

[0051] The tightening device for the spark plug bushing of the cylinder head provided by the present application saves manpower and time, improves work efficiency, and reduces the production beat. At the same time, the torque and moment of the spark plug bushing of the cylinder head are also controlled, improving the error tolerance and consistency.

[0052] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is the difference from other embodiments. The same or similar parts among the embodiments can be referred to each other.

[0053] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model.
