Embodiment 1

[0020] see Figure 1-4 , the present invention provides a protective structure for detecting the sealing effect of an automobile engine cylinder head, comprising a protective cover 1, the two sides of the top of the protective cover 1 are fixedly provided with chute seats 2, and the outer sides of the inner sides of the two chute seats 2 are fixed There is a forward and reverse rotation motor 4, the output shafts of the two forward and reverse rotation motors 4 are fixedly connected with a screw rod 5, and a slider 16 is threadedly sleeved in the middle of the two screw rods 5, and the two sliders 16 are respectively slidably arranged in the phase. Inside the corresponding chute seat 2 , the top ends of the two sliders 16 are fixedly provided with L-shaped anti-fall off splints 9 , the inner sides of the two L-shaped anti-fall off splints 9 are fixedly provided with anti-skid pads 7 , and the two anti-skid pads 7 There are several anti-skid grooves 8 on the inner side of the p...

Embodiment 2

[0028] The protective layer assembly 6 includes a thermal insulation and anti-scalding protection layer 61, the thermal insulation and anti-scalding protection layer 61 is fixedly arranged on the inner wall of the protective cover 1, and the inner wall of the thermal insulation and anti-scalding protection layer 61 is fixedly provided with an anti-corrosion protection layer 62. The inner wall of the layer 62 is fixedly provided with a waterproof protective layer 63;

[0029] Specifically, as figure 1 , image 3 , Figure 4 As shown, the provided protective cover 1 is convenient to avoid to a greater extent the potential safety hazard caused by the high-pressure gas when air leakage occurs during the detection process to the staff. Hot protection, the anti-corrosion protective layer 62 is convenient to improve the corrosion resistance of the protective cover 1, and the waterproof protective layer 63 is convenient to improve the waterproof performance of the protective cover 1...

Abstract

The invention discloses a protection structure for detecting the sealing effect of an automobile engine cylinder cover, and relates to the technical field of automobile engine detection, the protection structure comprises a protection cover, the two sides of the top end of the protection cover are fixedly provided with sliding groove seats, and the outer sides of the inner sides of the two sliding groove seats are fixedly provided with positive and negative rotation motors; the device has the beneficial effects that the output shafts of the two forward and reverse rotation motors are controlled to rotate, and the output shafts of the two forward and reverse rotation motors rotate to drive the two screws to rotate; the two screws rotate to drive the two sliding blocks to be in sliding fit with the two sliding groove bases through threaded fit with the two sliding blocks, and the two sliding blocks are in sliding fit with the two sliding groove bases to conduct transverse displacement to drive the two L-shaped anti-disengaging clamping plates to conduct transverse displacement. And the two L-shaped anti-falling clamping plates move transversely to drive the two anti-skid pads to clamp and fix the detection end of the cylinder pressure gauge, so that better anti-falling protection is provided.

Description

technical field [0001] The invention relates to a protective structure, in particular to a protective structure for detecting the sealing effect of a cylinder head of an automobile engine, belonging to the technical field of automobile engine detection. Background technique [0002] The engine cylinder head is used to close the cylinder and form the combustion chamber. The cylinder head belongs to the valve mechanism in the internal combustion engine. It is mainly used to close the upper part of the cylinder to form the combustion chamber and serve as the support for the camshaft and rocker shaft as well as the intake and exhaust pipes. , Mainly suck the air into the cylinder, the spark plug ignites the combustible mixed gas, drives the piston to do work, and the exhaust gas is discharged from the exhaust pipe. The engine cylinder head is mainly divided into a side valve type engine cylinder head and an overhead valve type engine cylinder head. The cylinder head of the side ...
