Description

Technical Field

[0001] The present invention relates to the technical field of airtight detection, and particularly to a quality detection tooling for an automobile engine end cover after die casting. Background Art

[0002] The engine end cover is also called the engine cylinder head. The engine cylinder head, cylinder liner and piston together form the combustion chamber of the diesel engine. It is one of the components that bear high temperature and high pressure working conditions. There are hole chambers formed on the engine cylinder head for the engine cylinder block to communicate with the outside for oil and gas. The bolt pre-tightening force borne by the top surface of the cylinder head is much greater than the combustion pressure. The bottom surface of the cylinder head bears the high-pressure gas pressure and thermal load generated by fuel combustion. If there is air leakage or other small problems in the engine cylinder head, it is easy to cause the possibility of engine cylinder head explosion and detonation. Therefore, it is necessary to perform airtightness detection on the engine cylinder head.

[0003] In the prior art, there is an engine cylinder head airtightness detection device with the publication number CN219064799U. By using a pneumatic valve group in cooperation with a high-pressure air pump, it can inflate and detect the engine cylinder head, and display data through a numerical control panel, which can improve the detection efficiency; by using a micro air pump in cooperation with clamping plates, it can clamp engine cylinder heads of different sizes, and the design of the protective pad can prevent damage to the engine cylinder head during the clamping process; by using a chute in cooperation with a slider and a detection rack, it can quickly assemble the engine cylinder head to be detected, improving the detection efficiency. The overall design of this engine cylinder head airtightness detection device is novel and the structure is simple, which is worthy of wide promotion and use.

[0004] Although the above device can improve the detection efficiency, there are still some defects in the actual detection process. Since the detection tooling of this detection device lacks an automatic loading and unloading function, when performing airtightness detection on the automobile engine end cover, the detection personnel need to use their hands, a robotic arm or a traveling crane to move the engine end cover on the production line to the detection tooling for detection. If manual handling is used, it will be time-consuming and laborious. If a robotic arm is used, the production cost will be greatly increased. If a traveling crane is used for handling, the worker needs to hang the hook on the engine end cover for hoisting, which will greatly reduce the detection efficiency of the device.

DETAILED DESCRIPTION

[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figures 1-9The tooling for quality inspection of automobile engine end cover after die casting shown in the figure comprises an inspection platform 1 and a top frame 2 fixedly connected to the inspection platform 1. The top frame 2 is provided with an inspection mechanism 3 for inspecting the air tightness of the end cover. The inspection mechanism 3 mainly cooperates with the pressure parameter control inspection device through a telescopic structure. The pressure inspection module performs pressure treatment on the engine end cover via the inspection interface and obtains pressure change timing information. The air tightness performance information is obtained according to the pressure change timing information and the temperature change inspection module is activated. The temperature change parameters are used to perform temperature change treatment on the cylinder body. The interactive temperature change inspection module obtains a temperature change image set for temperature change analysis, obtains the coordinates of the leakage point, and realizes the air tightness inspection of the engine end cover.

[0031] A conveyor frame 4 is provided at the front side of the test bench 1, and a conveyor mechanism 5 for conveying the engine end cover is provided on the conveyor frame 4. The conveyor mechanism 5 is mainly composed of a motor, a conveyor roller and a conveyor belt, and a limit block for limiting the position of the engine end cover is provided on the conveyor belt to ensure the position of the engine. At the same time, the conveyor mechanism 5 is intermittently transmitted through a program to ensure that the engine end cover is accurately moved to the front of the test bench 1. A top groove 6 is opened through the top of the test bench 1. A pair of loading platforms 7 are fixedly connected between the top of the test bench 1 and the top of the conveyor frame 4, and the loading platform 7 is arranged on both sides of the top groove 6, and a blocking mechanism for blocking the bottom end of the end cover is arranged in the top groove 6, and a loading frame 8 is slidably connected to the bottom end of the loading platform 7, and a loading plate 9 is slidably connected to the inner side of the loading frame 8, and four plug blocks 10 for inserting into the side holes of the end cover are arranged on the side close to the loading plate 9, and a slide groove 11 is opened on the side away from the loading plate 9, and a T-block 12 is slidably connected to the inner side of the slide groove 11, and a driving mechanism for driving the T-block 12 to move is arranged on the loading platform 7, and an adjusting mechanism for adjusting the position of the T-block 12 is arranged at the bottom end of the loading platform 7;

[0032] The driving mechanism includes a driving motor 13, and a pair of driving motors 13 are provided. A pair of top plates 14 are fixedly connected to the top of the loading platform 7, and a threaded rod 15 is rotatably connected between the top plates 14. The driving motors 13 are fixedly connected to the rear side of the loading platform 7, and the output end of the driving motor 13 passes through the top plate 14 and is fixedly connected to the side wall of the threaded rod 15. An L-shaped block 16 is slidably connected to the side away from the top of the loading platform 7, and the threaded rod 15 penetrates and is threadedly connected to the inner wall of the L-shaped block 16. The side wall of the L-shaped block 16 and the side plates 17 located on the front and rear sides of the T-shaped block 12 are fixedly connected. Through the setting of the side plates 17, not only can the T-shaped block 12 be pushed to slide forward and backward, but also the left and right movement of the T-shaped block 12 will not be hindered;

[0033] The adjusting mechanism includes adjusting rods 18. There are a pair of adjusting rods 18, and both adjusting rods 18 penetrate and are slidably connected to the top end of the T-shaped block 12. A top spring 36 is fixedly connected between the bottom end of the T-shaped block 12 and the outer wall of the adjusting rod 18. A straight groove 19 is opened at the bottom end of the feeding table 7. An inclined groove 20 is opened at the front side of the straight groove 19. A transverse groove 21 is opened at the front side of the straight groove 19. A U-shaped groove 22 is opened at the bottom end of the feeding table 7, and one end of the U-shaped groove 22 communicates with the front end of the inclined groove 20. The other side of the U-shaped groove 22 is connected to the side end of the transverse groove 21. An indented groove 23 is opened at a position beside the inclined groove 20 inside the U-shaped groove 22. The connection between the groove 23 and the U-shaped groove 22 is inclined, so that there is a step between the groove 23 and the inclined groove 20, which can limit the sliding position of the adjusting rod 18 and ensure that the adjusting rod 18 can move from the groove 23 into the U-shaped groove 22. The top end of the adjusting rod 18 is inserted into the inside of the straight groove 19, and the top end of the adjusting rod 18 is set as a smooth arc surface, which is convenient for the adjusting rod 18 to slide out of the groove 23 more smoothly;

[0034] A moving groove 34 is opened at the inner top end of the feeding frame 8. A moving plate 35 is fixedly connected to the top end of the feeding plate 9 corresponding to the inside of the moving groove 34. A plurality of feeding springs 24 are fixedly connected between the side wall of the moving plate 35 and the inside of the moving groove 34. Through the settings of the moving plate 35, the moving groove 34 and the feeding springs 24, it is convenient to pull the feeding plate 9 to reset. A plurality of reset springs 25 are fixedly connected between the inside of the sliding groove 11 and the side wall of the T-shaped block 12. Through the reset springs 25, it is convenient to push the T-shaped block 12 to reset and ensure that after the detection is completed, the feeding frame 8 can be driven to move immediately;

[0035] When performing quality inspection on the engine end cover, the die-cast engine end cover is conveyed to the front of the inspection table 1 through the conveying mechanism 5 on the conveying frame 4 (at this time, the feeding frame 8 is located on the inspection table 1, and the adjusting rod 18 slides inside the straight groove 19, which will not affect the normal conveying of the engine end cover on the conveyor belt). Subsequently, the control drive motor 13 is started to drive the threaded rod 15 to rotate, and then drive the L-shaped block 16 connected by threads to slide on the feeding table 7. At the same time, the T-shaped block 12 is driven to move through the side plate 17. Since there is no restriction on the front side of the feeding frame 8 at this time, when the T-shaped block 12 moves, the feeding plate 9 and the feeding frame 8 will be pushed to slide by the elastic force of the reset spring 25, and at the same time, the adjusting rod 18 will be driven to slide inside the straight groove 19. Then, when the feeding plate 9 moves to the conveying frame 4 and is located on both sides of the engine end cover, the feeding frame 8 is restricted at this time and cannot move forward continuously (the sliding position of the feeding frame 8 can be restricted by the groove opened at the bottom end of the feeding table 7, which is a mature technology in the prior art and will not be described in detail here);

[0036] Furthermore, under the continuous push of the side plate 17, the T-shaped block 12 will continue to move. At this time, the adjusting rod 18 slides out of the inner side of the straight groove 19 and slides into the inclined groove 20. At the same time, with the continuous movement of the T-shaped block 12, the return spring 25 will be gradually compressed. Subsequently, under the action of the inclined groove 20, the adjusting rod 18 will be gradually squeezed and drive the T-shaped block 12 and the feeding plate 9 to slide inside the feeding frame 8. At the same time, the insertion block 10 will be driven to insert into the side hole of the engine end cover. During this process, the moving plate 35 will be driven to slide in the moving groove 34, and at the same time, the feeding spring 24 will be gradually compressed, and the T-shaped block 12 will slide between the side plates 17. Subsequently, the adjusting rod 18 slides out of the inclined groove 20 and slides into the U-shaped groove 22 and is located below the groove 23. Then, under the elastic force of the upper spring 36, the top end of the adjusting rod 18 is pushed into the groove 23. Due to the limitation of the step between the groove 23 and the inclined groove 20, the adjusting rod 18 cannot slide into the inclined groove 20. Subsequently, the driving motor 13 can be controlled to reverse and drive the L-shaped block 16 to move backward. At the same time, the T-shaped block 12 is driven to move backward by the side plate 17. At this time, the compression of the return spring 25 will be gradually released. At the same time, the adjusting rod 18 is driven to slide out of the inclined surface of the groove 23 and slide into the U-shaped groove 22, and at the same time, the adjusting rod 18 is squeezed downward and the upper spring 36 is stretched. Subsequently, when the T-shaped block 12 is reset, it can drive the feeding frame 8 and the feeding plate 9 to move under the thrust of the side plate 17, and at the same time, drive the engine end cover to move (it should be noted here that the heights of the conveying rack 4 and the inspection table 1 can be lower than the height of the conveyor belt on the conveying mechanism 5 to avoid abrasion of the engine end cover during the loading and unloading process. And when the engine end cover is removed from the conveyor belt, the conveyor belt is made of rubber material and will not damage the engine end cover);

[0037] Subsequently, the loading frame 8 and the insertion block 10 transfer the engine end cover below the detection mechanism 3. At the same time, the adjusting rod 18 moves to the rear end of the U-shaped groove 22. Then, under the elastic force of the loading spring 24, the loading plate 9, the T-shaped block 12 and the adjusting rod 18 are pushed to slide, driving the adjusting rod 18 to slide in the transverse end of the U-shaped groove 22, and driving the insertion block 10 to move to both sides (it will not move out of the engine side hole and will not hinder the normal detection of the device). Subsequently, the driving motor 13 can be controlled to stop running. Then, the detection mechanism 3 and the plugging mechanism are controlled to operate to perform airtight detection on the engine end cover. After the detection is completed, the driving motor 13 can be controlled to rotate forward. Driven by the side plate 17, the T-shaped block 12 is driven to move forward, and at the same time, the adjusting rod 18 is driven to slide in the other longitudinal end of the U-shaped groove 22. Then, the engine end cover is transferred to the conveyor belt. At this time, the adjusting rod 18 moves to the front end of the U-shaped groove 22, thus releasing the limit on the adjusting rod 18. Then, under the elastic force of the loading spring 24, the T-shaped block 12 is pushed to reset, driving the adjusting rod 18 to enter the straight groove 19 through the transverse groove 21, and at the same time driving the insertion block 10 to move out of the side hole of the engine end cover. Finally, the driving motor 13 can be controlled to reverse to remove the loading frame 8, and then the conveying mechanism 5 is controlled to start to convey the next engine end cover over.

[0038] To improve the applicable range of the device, adjusting grooves 29 are provided on the sides of the loading plate 9 close to each other. Four adjusting plates 30 are slidably arranged inside the adjusting grooves 29. Screw rods 31 are fixedly connected to the side walls of the four adjusting plates 30. Thread grooves 32 adapted to the screw rods 31 are provided on the side walls of the four insertion blocks 10, and the insertion blocks 10 are made of rubber material.

[0039] The side walls of the adjusting plates 30 are all threadedly connected with bolts 33, and the side walls of the bolts 33 are in contact with the inside of the adjusting grooves 29.

[0040] When the insertion block 10 needs to be replaced according to different models of engines, the insertion block 10 can be rotated and unscrewed from the screw rod 31, and then the replacement insertion block 10 can be screwed onto the screw rod 31 through the thread groove 32. When the distance between the insertion blocks 10 needs to be adjusted, a tool is used to rotate the bolt 33 to release the restriction on the adjusting plate 30, and then the adjusting plate 30 can be pushed to slide inside the adjusting groove 29. After the adjustment is completed, the bolt 33 is tightened in the reverse direction with a workpiece.

[0041] To improve the automation efficiency of the device, the plugging mechanism includes an electric telescopic cylinder 26. A pair of electric telescopic cylinders 26 are provided, and the electric telescopic cylinders 26 are fixedly connected inside the detection table 1. A plugging block 27 for plugging the bottom end of the end cover is fixedly connected between the output ends of the electric telescopic cylinders 26. A travel switch 28 is fixedly connected to the top end of one of the loading platforms 7, and the travel switch 28 is electrically connected to the electric telescopic cylinder 26, the detection mechanism 3 and the driving mechanism through a controller.

[0042] When the driving motor 13 operates for the automatic loading and unloading of the engine end cover, when the engine end cover is moved below the detection mechanism 3, the L-shaped block 16 will touch the travel switch 28. Subsequently, the travel switch 28 transmits a signal to the controller. The controller controls the driving mechanism to stop operating and controls the detection mechanism 3 and the electric telescopic cylinder 26 to operate. Subsequently, the telescopic component on the detection mechanism 3 pushes the detection module above the engine end cover. At the same time, the electric telescopic cylinder 26 drives the plugging block 27 to move upward to plug the bottom end of the engine end cover, so as to automatically perform airtight detection on the engine end cover, further improving the automation efficiency of the device.

[0043] The above shows and describes the basic principles, main features and advantages of the present invention.

[0044] Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the principles described in the specification are only the principles of the present invention.
