Description

Technical Field

[0001] The utility model relates to the technical field of fuel injection pump body processing, and specifically relates to a drilling equipment for the connecting holes of a fuel injection pump body. Background Art

[0002] The fuel injection pump is the most important component in the fuel supply system of a diesel engine. Its function is to change the fuel from low pressure to high pressure. The fuel injection pump raises the oil pressure in the high-pressure oil circuit to more than 100 kPa, and injects diesel into the cylinder regularly and quantitatively according to the engine power, and mixes with air for combustion.

[0003] At present, when the existing fuel injection pumps are processed and produced, operations such as drilling and reaming need to be carried out on a drilling machine. Since the surface of the fuel injection pump is irregular in shape, it is easy to cause the clamping surface of the fixture to the fuel injection pump to be insufficient, resulting in problems such as loosening and slipping of the fuel injection pump during processing.

[0004] The reason for this problem is that when the existing fuel injection pumps are processed and produced, operations such as drilling and reaming need to be carried out on a drilling machine. Since the fixtures used to clamp the fuel injection pump on the drilling machine are mostly flat-jawed pliers, and the surface of the fuel injection pump is irregular in various shapes. When the fixture clamps the fuel injection pump, the fixture will clamp against the protruding part of the fuel injection pump surface, resulting in fewer clamping points on the fuel injection pump and insufficient clamping, which is likely to cause the reaming force during processing and lead to the situation of loosening and slipping of the fuel injection pump. In view of the deficiencies of the existing technology, we propose a drilling equipment for the connecting holes of a fuel injection pump body to solve the above problems. Content of the Utility Model

[0005] In view of the deficiencies of the existing technology, the utility model provides a drilling equipment for the connecting holes of a fuel injection pump body, which solves the problem that when the existing fuel injection pumps are processed and produced, operations such as drilling and reaming need to be carried out on a drilling machine. Since the surface of the fuel injection pump is irregular in shape, it is easy to cause the clamping surface of the fixture to the fuel injection pump to be insufficient, resulting in problems such as loosening and slipping of the fuel injection pump during processing.

[0006] To achieve the above purposes, the utility model is realized through the following technical solutions: A drilling equipment for the connecting holes of a fuel injection pump body includes a fixture arranged on the drilling equipment. A clamping assembly is provided on the side wall of the fixture. The clamping assembly includes a side plate, a right-angle plate, an electric telescopic rod and a sponge pad.

[0007] The side plate is movably inserted into the side wall of the fixture. The right-angle plate is slidably connected inside the side plate. The electric telescopic rod is fixedly connected between the side plate and the right-angle plate. The sponge pads are respectively fixedly connected to the side wall of the side plate and the bottom of the right-angle plate.

[0008] Preferably, a convex member is fixedly connected to the side wall of the side plate, a chute is formed in the side wall of the fixture, and the convex member is slidably connected to the inside of the chute.

[0009] Preferably, a clamping groove is formed in the side wall of the convex member, a clamping rod is slidably connected to the side wall of the side plate, the clamping rod is movably inserted into the clamping groove, and the clamping rod is used to limit the convex member.

[0010] Preferably, a screw rod is threadedly connected to the top of the fixture, a trapezoidal plate is connected to the bottom of the screw rod for working, and the trapezoidal plate is slidably connected to the inside of the fixture.

[0011] Preferably, the clamping rod is slidably connected to both sides of the trapezoidal plate, and the trapezoidal plate is used to move the clamping rod.

[0012] Preferably, a groove is formed in the top of the side plate, and the right-angled plate is slidably connected to the inside of the groove.

[0013] Preferably, both ends of the electric telescopic rod are respectively fixedly connected to the inside of the groove and the bottom of the right-angled plate.
