[0002] The engine cylinder head is used to seal the cylinder and form a combustion chamber. The side-valve engine cylinder head is cast with a water jacket, water inlet hole, water outlet hole, spark plug hole, bolt hole, combustion chamber, etc. The cylinder head belongs to the valve mechanism in the internal combustion engine, which is mainly used to seal the upper part of the cylinder and form a combustion chamber. It also serves as a support for the camshaft, rocker arm shaft and intake and exhaust pipes. It mainly sucks air into the cylinder, and the spark plug ignites the combustible mixed gas, drives the piston to work, and the exhaust gas is discharged from the exhaust pipe.

[0003] As the name implies, a clamp is a tool used to fix the engine cylinder head on a workbench. When the engine cylinder head is being repaired, a clamp is needed. Traditional clamps are mostly fixed with bolts and a workbench, and then the fixing mechanism on the clamp is inserted into the hole of the engine cylinder head for squeezing and fixing, thereby achieving the purpose of fixing the engine cylinder head on the workbench.

[0004] The problem with this fixing method is that when the holes of the engine cylinder head that is being repaired continuously are not in the same position, it is necessary to constantly remove the bolts on the clamp to adjust the position of the clamp to adapt to the position of the engine cylinder head hole for fixing. This operation method is inefficient and time-consuming and labor-intensive.

[0005] With respect to the existing related technologies, it is believed that the following defects exist:; Therefore, an engine cylinder head fixing clamp is proposed to address the above problems. Utility Model Content

[0006] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, the utility model provides an engine cylinder head fixing fixture.

[0007] The technical solution adopted by the utility model to solve its technical problems is: an engine cylinder head fixing fixture described in the utility model comprises a workbench, an engine cylinder head body is arranged on the top of the workbench, four sliding grooves are opened on the top of the workbench and are symmetrically arranged in groups of two, a sliding block is slidably connected inside the sliding groove, one side of the sliding block is slidably connected to an "L"-shaped positioning block, a plurality of positioning grooves are opened on the top surface of the workbench, a telescopic block is slidably connected to the top of the sliding block, a limiting hole is opened on one side of the telescopic block, a limiting rod is slidably connected to the limiting rod, the top of the telescopic block is slidably connected to a pressure plate, and a rubber gasket is fixedly installed on the bottom of the pressure plate.

[0008] Furthermore, an elastic membrane is fixedly installed inside the positioning groove, and the positioning block is made of rubber material and the short arm end is wider than the positioning groove.

[0009] Furthermore, a plurality of arc grooves are provided on both sides of the pressure plate, a placement groove is provided on one side of the telescopic block, a rotating ball is embedded inside the placement groove, the surface of the rotating ball is made of magnetic material, and the surface of the arc groove is also made of magnetic material.

[0010] Furthermore, a spring is fixedly installed inside the placement groove, a push plate is fixedly installed at one end of the spring, and the push plate is in contact with the rotating ball.

[0011] Furthermore, two symmetrically arranged elastic balls are fixedly installed on the inner wall of the arc groove, shrinkage holes are opened on the surface of the elastic balls, and a connecting tube connected to the inside of the elastic balls is fixedly installed inside the pressure plate, and the other end of the connecting tube is connected to another arc groove.

[0012] Furthermore, a multi-stage telescopic plate is fixedly installed inside the sliding groove, and the multi-stage telescopic plate is composed of a plurality of hollow plates connected in a sliding manner.

[0013] The utility model is beneficial in that:

[0014] 1. The utility model places the engine cylinder head body to be processed or repaired on the workbench, and then slides the sliding block in the sliding groove. When the sliding block moves, it will move with the multi-stage telescopic plate, thereby achieving the function of closing the sliding groove and reducing the impurities falling into the sliding groove to affect the normal sliding of the sliding block. After the sliding block is moved to a suitable position and aligned with the hole on the engine cylinder head body, the positioning block is inserted into the positioning groove to drive the sliding block to be fixed. At this time, the telescopic block and the top pressure plate are moved, so that the pressure plate with the rubber gasket is inserted into the hole of the engine cylinder head body for pressing. At this time, the limiting rod is inserted into the limiting hole for fixing, and then the telescopic block and the pressure plate are fixed. The pressure plate and the gasket are used to assist in fixing the engine cylinder head body. The rubber gasket can protect the hole of the engine cylinder head body and prevent the hole of the engine cylinder head body from being scratched by hard materials. At the same time, the rubber gasket is deformed to make up for the distance between the two limiting holes, ensuring that the limiting rod can be inserted into the limiting hole for fixing. The structure designed above can replace the function of the bolt fixing fixture, and can also be quickly adjusted when encountering holes in the engine cylinder head body at different positions, without the need for tedious disassembly of bolts to cause inefficiency.

[0015] 2. When the pressure plate of the utility model is slid, the arc groove on the side of the pressure plate will lift up the rotating ball, causing the rotating ball to shrink into the placement groove, thereby facilitating the movement of the pressure plate; as the pressure plate moves, the spring in the placement groove pushes the push plate and the rotating ball to move in the direction of the arc groove again, causing the rotating ball to be stuck in the arc groove just below and fixed by magnetism; when the rotating ball enters the arc groove, it will squeeze the elastic ball inside, causing the gas in the elastic ball to quickly fill the connecting pipe and spray out; the sprayed gas is used to blow and clean the arc grooves on both sides, thereby facilitating the next arc groove and the rotating ball to cooperate to achieve rapid adsorption and fixation, thereby reducing the shaking of the pressure plate and giving it better pressing stability.

[0024] See also Figure 1-5 As shown, an engine cylinder head fixing fixture comprises a workbench 1, an engine cylinder head body 2 is arranged on the top of the workbench 1, four sliding grooves 3 are opened on the top of the workbench 1 and are symmetrically arranged in groups of two, a sliding block 4 is slidably connected inside the sliding groove 3, and an "L"-shaped positioning block 5 is slidably connected to one side of the sliding block 4, a plurality of positioning grooves 6 are opened on the top surface of the workbench 1, a telescopic block 7 is slidably connected to the top of the sliding block 4, a limiting hole 8 is opened on one side of the telescopic block 7, a limiting rod 9 is slidably connected to one side of the sliding block 4, a pressing plate 10 is slidably connected to the top of the telescopic block 7, and a rubber gasket 11 is fixedly installed on the bottom of the pressing plate 10.

[0025] Specifically, an elastic membrane 12 is fixedly installed inside the positioning groove 6, the positioning block 5 is made of rubber and the short arm end is wider than the positioning groove 6, and a multi-stage telescopic plate 20 is fixedly installed inside the sliding groove 3. The multi-stage telescopic plate 20 is composed of several hollow plates slidably connected.

[0026] During operation, the engine cylinder head body 2 to be processed or repaired is placed on the workbench 1, and the sliding block 4 in the sliding groove 3 is slid. The sliding block 4 will move with the multi-stage telescopic plate 20 when moving, thereby achieving the function of closing the sliding groove 3 and reducing impurities falling into the sliding groove 3 to affect the normal sliding of the sliding block 4. After the sliding block 4 is moved to a suitable position and aligned with the hole on the engine cylinder head body 2, the positioning block 5 is inserted into the positioning groove 6 to drive the sliding block 4 to be fixed. At this time, the telescopic block 7 and the top pressure plate 10 are moved, so that the pressure plate 10 with the rubber gasket 11 is inserted into the hole of the engine cylinder head body 2 for pressing. At this time, the limiting rod 9 is inserted into the limiting hole 8 for fixing, and then the telescopic block 7 and the pressure plate 10 are fixed. The pressure plate 10 and the gasket 11 are used to assist in fixing the engine cylinder head body 2. The rubber gasket 11 can protect the hole of the engine cylinder head body 2 and prevent the hole of the engine cylinder head body 2 from being scratched by hard materials. At the same time, the rubber gasket 11 is deformed to make up for the distance between the two limiting holes 8, ensuring that the limiting rod 9 can be inserted into the limiting hole 8 for fixing. The structure designed above can replace the role of the bolt fixing fixture, and can also be quickly adjusted when encountering holes in the engine cylinder head body 2 at different positions, without the need for cumbersome disassembly of bolts to cause inefficiency.

[0027] A plurality of arc grooves 15 are provided on both sides of the pressing plate 10, and a placement groove 13 is provided on one side of the telescopic block 7. A rotating ball 14 is embedded in the placement groove 13. The surface of the rotating ball 14 is made of magnetic material, and the surface of the arc groove 15 is also made of magnetic material.

[0028] Specifically, a spring 16 is fixedly installed inside the placement groove 13, a push plate 17 is fixedly installed at one end of the spring 16, the push plate 17 is in contact with the rotating ball 14, two symmetrically arranged elastic balls 18 are fixedly installed on the inner wall of the arc groove 15, and shrinkage holes are opened on the surface of the elastic balls 18, a connecting pipe 19 connected to the inside of the elastic balls 18 is fixedly installed inside the pressure plate 10, and the other end of the connecting pipe 19 is connected to another arc groove 15.

[0029] During operation, when the pressing plate 10 is slid, the arc groove 15 on the side of the pressing plate 10 will lift up the rotating ball 14, causing the rotating ball 14 to shrink into the placement groove 13, thereby facilitating the movement of the pressing plate 10. As the pressing plate 10 moves, the spring 16 in the placement groove 13 pushes the push plate 17 and the rotating ball 14 to move toward the arc groove 15 again, so that the rotating ball 14 is stuck in the arc groove 15 directly below and is fixed by magnetic attraction. When the rotating ball 14 enters the arc groove 15, it will squeeze the elastic ball 18 inside, so that the gas in the elastic ball 18 is quickly filled into the connecting pipe 19 and ejected. The ejected gas is used to blow and clean the arc grooves 15 on both sides, so that the next arc groove 15 and the rotating ball 14 can be quickly adsorbed and fixed when they cooperate, thereby reducing the shaking of the pressing plate 10 and making it have better pressing stability.

[0030] The working principle is to place the engine cylinder head body 2 to be processed or repaired on the workbench 1, and then slide the sliding block 4 in the sliding groove 3. The sliding block 4 will move with the multi-stage telescopic plate 20 when moving, thereby achieving the function of closing the sliding groove 3 and reducing impurities falling into the sliding groove 3 to affect the normal sliding of the sliding block 4. After the sliding block 4 is moved to a suitable position and aligned with the hole on the engine cylinder head body 2, the positioning block 5 is inserted into the positioning groove 6 to drive the sliding block 4 to be fixed. At this time, the telescopic block 7 and the top pressure plate 10 are moved, so that the pressure plate 10 with the rubber gasket 11 is inserted into the hole of the engine cylinder head body 2 for pressing. At this time, the limiting rod 9 is inserted into the limiting hole 8 for fixing, and then the telescopic block 7 and the pressure plate 10 are fixed. The pressure plate 10 and the gasket 11 are used to assist in fixing the engine cylinder head body 2. The rubber gasket 11 can protect the hole of the engine cylinder head body 2 and prevent the hole of the engine cylinder head body 2 from being scratched by hard materials. At the same time, the rubber gasket 11 is deformed to make up for the distance between the two limiting holes 8, ensuring that the limiting rod 9 can be inserted into the limiting hole 8 for fixing. The structure designed above can replace the role of the bolt fixing fixture, and can also be quickly adjusted when encountering holes in the engine cylinder head body 2 at different positions, without the need for cumbersome disassembly of bolts to cause inefficiency.

[0031] When the pressing plate 10 is slid, the arc groove 15 on the side of the pressing plate 10 will lift up the rotating ball 14, causing the rotating ball 14 to shrink into the placement groove 13, thereby facilitating the movement of the pressing plate 10. As the pressing plate 10 moves, the spring 16 in the placement groove 13 pushes the push plate 17 and the rotating ball 14 to move toward the arc groove 15 again, so that the rotating ball 14 is stuck in the arc groove 15 directly below and is fixed by magnetic attraction. When the rotating ball 14 enters the arc groove 15, it will squeeze the elastic ball 18 inside, so that the gas in the elastic ball 18 is quickly filled into the connecting pipe 19 and ejected. The ejected gas is used to blow and clean the arc grooves 15 on both sides, so that the next arc groove 15 and the rotating ball 14 can be quickly adsorbed and fixed when they cooperate, thereby reducing the shaking of the pressing plate 10 and making it have better pressing stability.
