[0002] Currently, the competition in the automotive industry is becoming increasingly fierce, and the performance of automobiles is crucial. The engine cylinder head determines the power and fuel consumption of the automobile. Therefore, the design of the engine cylinder head is becoming more and more perfect, and the structure is becoming more and more complex. As a result, more and more positions need to be paid attention to during the production of the cylinder head, such as the core breakage of the water channel, the core breakage of the oil cavity foot, the height of the combustion chamber, etc., all of which require great attention.

[0003] Currently, relying solely on the naked eye of workers, the accuracy cannot be 100% accurate. The height of the combustion chamber needs to be fully inspected by a coordinate measuring machine, which not only consumes time and effort but also has a high cost. If these problems are not identified and flow to the client or are directly installed on the engine, it will cause greater losses.

[0004] Therefore, we propose to design a multi-functional gauge for an automobile engine cylinder head. Content of the Utility Model

[0024] In order to make the purpose, technical solution and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please refer to Figures 1-5 , the present utility model provides a multi-functional fixture for an automobile engine cylinder head, including a fixture mounting block 1 and a fixture bottom plate 2, and a dial indicator 3 is arranged on the top of the fixture mounting block 1.

[0026] In this embodiment, four dial indicators 3 are provided, and the four dial indicators 3 are evenly distributed at both ends of the top of the fixture mounting block 1, which is convenient for detecting the cylinder head combustion chamber.

[0027] A detection screw 4 penetrates through the top of the fixture mounting block 1. On the middle part of the side of the bottom of the fixture mounting block 1 far away from the dial indicator 3, a fixture X-direction calibration block 8 is arranged. On both sides of the fixture X-direction calibration block 8, fixture Y-direction calibration blocks 9 are arranged, and a fixture Z-direction calibration block 10 is arranged at the bottom of the fixture mounting block 1.

[0028] Among them, three fixture Z-direction calibration blocks 10 are provided. The connection lines between the centers of the three fixture Z-direction calibration blocks 10 are arranged in a triangular shape, which is convenient for longitudinally calibrating the fixture mounting block 1. A calibration base 11 corresponding to the fixture Z-direction calibration block 10 is provided at the top of the fixture bottom plate 2, which is convenient for cooperating with the fixture mounting block 1 to calibrate the fixture mounting block 1 to adapt to subsequent assembly on the cylinder head.

[0029] Two guide posts 5 are fixedly connected to the diagonal corners at the top of the fixture bottom plate 2. Guide holes 501 corresponding to the two guide posts 5 are formed at the diagonal corners of the fixture mounting block 1. The guide posts 5 penetrate through the guide holes 501 and are slidably connected thereto, which is convenient for assembling and positioning between the fixture mounting block 1 and the fixture bottom plate 2 and calibrating the fixture.

[0030] Support columns 6 are fixedly connected to the four corners at the bottom of the fixture bottom plate 2. Two dial indicator calibration blocks 7 are provided at the top of the fixture bottom plate 2. Handles 12 are fixedly connected to both ends of the fixture mounting block 1 and the fixture bottom plate 2.

[0031] During use, first calibrate the dial indicator 3 on the fixture mounting block 1 on the dial indicator calibration block 7. After calibration, the zero position on the dial indicator 3 is equivalent to the theoretical value of the height of the cylinder head combustion chamber.

[0032] Then place the fixture mounting block 1 on the rough reference of the cylinder head for positioning. Then, the number on the dial indicator 3 can be used to check whether the height of the mold combustion chamber is within the tolerance range.

[0033] Subsequently, insert the corresponding blue detection screw 4 into the water channel feet and oil cavity feet that often have problems to detect whether the oil cavity and water channel are blocked. During specific use, according to needs, the positions to be detected can also be designed, and the number of detection screws 4 can be increased.

[0034] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be combined with each other in any way.
