Description

Technical Field

[0001] The invention relates to the technical field of cylinder liner detection, in particular to an automobile cylinder liner detection device. Background Art

[0002] Automobile cylinder liner is the abbreviation of engine cylinder liner, which is embedded in the cylinder barrel of the cylinder body and forms a combustion chamber together with the piston and cylinder head. Cylinder liners are divided into two categories: dry cylinder liners and wet cylinder liners. Automobile cylinder liner testing equipment is a series of equipment specially used to test the quality, performance and size of automobile cylinder liners. These equipment play an important role in the fields of automobile maintenance, manufacturing and testing, ensuring that the quality of cylinder liners meets the standards, thereby ensuring the normal operation of the engine. When the cylinder liner is produced, the inner roundness of the cylinder liner needs to be tested.

[0003] For example, a vehicle cylinder liner detection device with publication number CN117109512A includes a support seat, a detection platform is rotatably installed on the top of the support seat, a plurality of clamping mechanisms for clamping and fixing the cylinder liner are installed on the detection platform, a detection component is used to detect the inner roundness of the cylinder liner, the detection component includes a detection probe, and a conveying mechanism is used to drive the plurality of clamping mechanisms to rotate around the center of the detection platform, and whenever any one of the clamping mechanisms is located directly below the detection component, the plurality of clamping mechanisms stop rotating around the center of the detection platform; the vehicle cylinder liner detection device, through the clamping mechanism and the cylinder liner being located directly below the detection component, automatically conveys the cylinder liner to the bottom of the detection component, and automatically performs detection, which helps to improve the cylinder liner detection efficiency, and automatically extends the detection component into the cylinder liner located at the bottom thereof through the second drive component, effectively reducing the driving source while improving the detection efficiency and making the detection more accurate.

[0004] Based on the search of the above patents and in combination with the devices in the prior art, it is found that when the existing cylinder liner detection devices detect the cylinder liner, most of them manually place the cylinder liner at the bottom of the detection component, and then extend the detection component into the cylinder liner for detection. Workers need to wait for the detection to be completed when taking and placing the cylinder liner. Each detection of a cylinder liner requires a long period of stagnation, resulting in low detection efficiency. In addition, since the cylinder liner arms of some models are thinner, if the clamping force is not strictly controlled, the cylinder liner will be deformed. In order to solve the problems existing in the prior art, the present application proposes an automobile cylinder liner detection device. Summary of the invention

When the undetected cylinder liner reaches the position of the laser rangefinder, the electric telescopic rod drives the support arm and the laser rangefinder to extend into the interior of the cylinder liner, and then the rotating mechanism drives the laser rangefinder to rotate to detect the inner diameter of the cylinder liner, so that the equipment can detect the inner diameter of the cylinder liner while the staff is taking and placing the cylinder liner, thereby reducing the waiting time of the staff and helping to improve the efficiency of detection.

When the undetected cylinder sleeve 4 reaches the position of the laser rangefinder 7, the electric telescopic rod 6 drives the support arm 8 and the laser rangefinder 7 to extend into the inside of the cylinder sleeve 4, and then drives the laser rangefinder 7 to rotate through the rotating mechanism to detect the inner diameter of the cylinder sleeve 4, so that the staff can detect the inner diameter of the cylinder sleeve 4 while taking and placing the cylinder sleeve 4, thereby reducing the waiting time of the staff and improving the efficiency of the detection.

[0046] Example 2

[0047] The automobile cylinder liner detection device provided in Example 1 is further optimized. Specifically, Figure 1-7 As shown,

[0048] A PLC controller 3 is fixed to one side of the first shell 1. The model of the PLC controller 3 is HS7-46MRT. A weight detector 52 is fixed inside the PLC controller 3. The measuring end of the top of the weight detector 52 is fixed to the suspension seat 10.

[0049] The use process of the automobile cylinder liner detection device provided by the present invention is as follows:

[0050] Technical principle: each time the second housing 9 moves to the position of the micro-trigger 51, the micro-trigger 51 is triggered by contact with the micro-trigger 51, and the micro-trigger 51 sends a stop signal to the PLC controller 3, and the rotation of the first synchronous motor 13 is controlled by the PLC controller 3, and the second housing 9 can stay for a long time. When the staff places the cylinder sleeve 4 on the suspended placement seat 10, the weight detector 52 detects that there is a heavy object and sends a start signal to the PLC controller 3, and the third synchronous motor 32 is controlled by the PLC controller 3 to start. The third synchronous motor 32 drives the driving rod 50 to rotate when rotating, and the driving rod 50 drives the threaded rod 47 to rotate through the transmission groove 49 and the transmission block 48 when rotating. The threaded rod 47 drives the second piston 54 to move when rotating. When the second piston 54 moves, the gas between the second piston 54 and the first piston 44 drives the first piston 44 to move. When the first piston 44 moves, it drives the push-pull block 38 to move through the fourth connecting arm 42 and the connecting block 43, and the push-pull block 38 moves to drive the straight gear The outer gear 34 rotates, and the spur-tooth outer gear 34 drives the driving ring 33 to rotate.

When the bearing 22 is stuck in the driving groove 16, the shaft The bearing 22 will drive the rotating wheel 15 to rotate. When the bearing 22 is disengaged from the driving groove 16, the outer side of the driving wheel 17 will be stuck in the inner part of the retaining groove 31 and slidably connected with the retaining groove 31, which will limit the rotation of the rotating wheel 15, thereby driving the rotating wheel 15 to rotate intermittently. When the rotating wheel 15 rotates, it will drive the first shaft sleeve 14 to rotate, and then drive the cylinder sleeve 4 to rotate intermittently, so that the staff can detect the inner diameter of the cylinder sleeve 4 while taking and placing the cylinder sleeve 4, thereby reducing the waiting time of the staff and helping to improve the efficiency of detection.
