Between cylinder cap one and cylinder cap two, the gripping block both ends are adjacent to cylinder cap one and cylinder cap two respectively, are arranged on the hold-down bolt
Spring.
As a kind of preferred embodiment of the utility model, the spring is arranged between screw hole and gripping block.
As a kind of preferred embodiment of the utility model, the height of the cylinder cap one is equal to the height of cylinder cap two.
As a kind of preferred embodiment of the utility model, described nestled bolt one end is welded with nuts, the spiral shell
Bolt cap is arranged on the outside of gripping block.
As a kind of preferred embodiment of the utility model, the positioning pin one is cylindrical shape.
As a kind of preferred embodiment of the utility model, the positioning pin two is rectangular shape.
The utility model has the beneficial effects that a kind of large-scale cylinder cap fixture of the utility model, including bottom plate, gripping block, pressure
Tight bolt, positioning pin one, positioning pin two, cylinder cap one, cylinder cap two, spring, nuts.
1. the fixture can be simultaneously to two large-scale engines by a gripping block when using large-scale cylinder cap fixture
Cylinder cap is positioned and is clamped, and processing efficiency can be effectively promoted；
2. the large size cylinder cap fixture is clamped two cylinder caps using compact heap after having good positioning, uses and compress spiral shell
The mode of bolt assembly and spring cooperation, therefore can ensure that compact heap can have enough pressing forces to act on two cylinder caps；
3. the large size cylinder cap fixture is novel in design, structurally reasonable, it is able to ascend chuck strength, also can be improved processing effect
Rate.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
The utility model provides a kind of technical solution referring to FIG. 1 to FIG. 4: a kind of large size cylinder cap fixture, including bottom plate 1,
Gripping block 2 and hold-down bolt 3 are separately installed with cylinder cap 1 and cylinder cap by positioning pin 1 and positioning pin 25 on the bottom plate 1
27, screw hole is provided on the bottom plate 1, the screw hole is arranged between positioning pin 1 and positioning pin 25, the gripping block 2
On be provided with through-hole, described 3 one end of hold-down bolt passes through through-hole and is meshed with screw hole by screw thread, and the hold-down bolt 3 is arranged
Between cylinder cap 1 and cylinder cap 27,2 both ends of gripping block are adjacent to cylinder cap 1 and cylinder cap 27, the hold-down bolt 3 respectively
On be arranged with spring 8.
As a kind of preferred embodiment of the utility model, the spring 8 is arranged between screw hole and gripping block 2.
As a kind of preferred embodiment of the utility model, the height of the cylinder cap 1 is equal to the height of cylinder cap 27.
As a kind of preferred embodiment of the utility model, described 3 one end of hold-down bolt is welded with nuts 9, described
The setting of nuts 9 is in 2 outside of gripping block.
As a kind of preferred embodiment of the utility model, the positioning pin 1 is cylindrical shape.
