Description

Technical Field

[0001] The utility model relates to the technical field of fuel injection pump body processing, in particular to a milling head for fuel injection pump body processing. Background Art

[0002] The fuel injection pump, also known as the high-pressure fuel pump, is an extremely important component in the engine fuel system. It provides the fuel system with appropriate fuel pressure and fuel source to enable it to operate efficiently. The function of the fuel injection pump is to spray diesel into the cylinder in a timely, quantitative, constant pressure and flexible manner according to the different working conditions of the diesel engine, so that it mixes with air and burns.

[0003] At present, when the injection pump body is milled, the synchronous spraying of cutting fluid is easy to wash down the lubricating fluid between the milling cutter and the milling machine, causing waste and causing the milling cutter to rotate unsmoothly;

[0004] The reason for this problem is that when the fuel injection pump body is produced, it will be milled by the milling cutter on the milling machine. In order to reduce the friction and wear between the milling cutter and the milling machine during rotation, the current milling cutter will be lubricated at the connection between the two. During the milling process, the milling cutter will simultaneously spray cutting fluid between the milling cutter and the fuel injection pump body to reduce the temperature of the two during milling. At this time, part of the cutting fluid will splash at the connection between the milling cutter and the milling machine, which is easy to wash down the lubricating fluid and cause waste, and cause the milling cutter to rotate unsmoothly. In view of the shortcomings of the existing technology, we propose a milling head for fuel injection pump body processing to solve the above problems. Utility Model Content

[0023] By providing a milling head for machining a fuel injection pump body in the embodiments of the present application, the problem that when milling the fuel injection pump body currently, the synchronous spraying of cutting fluid easily flushes down the lubricating fluid between the milling cutter and the milling machine, causing waste and resulting in unsmooth rotation of the milling cutter, is solved.

[0024] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0025] The embodiments of the present utility model disclose a milling head for machining a fuel injection pump body.

[0026] According to the attached Figures 1-5 As shown, a milling head for machining a fuel injection pump body includes a power milling head 1, and a protection component 2 is arranged on the side wall of the power milling head 1. The protection component 2 includes a cylinder 201, a support rod 202, a movable rod 203, a flexible waterproof cloth 204 and an inner ring part 205;

[0027] For the specific functions and operations of the power milling head 1, reference can be made to a right-angle milling head of model MT1-250.

[0028] The cylinder 201 is threadedly connected to the side wall of the power milling head 1. The outer peripheral wall of the milling cutter sleeved by the cylinder 201, the support rod 202 is rotatably connected to the inner wall of the cylinder 201. The flexible waterproof cloth 204 is fixedly connected to both sides of the support rod 202. The movable rod 203 is rotatably connected between the inner ring member 205 and the support rod 202. The inner ring member 205 is slidably connected to the inner wall of the cylinder 201. By providing the protection component 2 at the connection between the power milling head 1 and the milling cutter, the flexible waterproof cloth 204 can shield and protect the connection part, avoiding the situation that during the milling process, the continuously sprayed cutting fluid is likely to wash down the lubricating fluid between the two, resulting in the milling cutter getting stuck.

[0029] The end of the flexible waterproof cloth 204 is fixedly connected to the inner wall of the cylinder 201, and the flexible waterproof cloth 204 can shield the sprayed cutting fluid.

[0030] Both sides of the cylinder 201 are provided with chutes 2011. Both sides of the inner ring member 205 are fixedly connected with connecting members 2051. The connecting members 2051 are slidably connected inside the chutes 2011. By moving the inner ring member 205 outwards, the movable rod 203 can be driven to move. At this time, the movable rod 203 can push the support rod 202 to rotate and drive the flexible waterproof cloth 204 to be folded up, making the flexible waterproof cloth 204 close to the outer peripheral wall of the milling cutter. Secondly, by performing the above operations in reverse, the flexible waterproof cloth 204 can be spread out, facilitating its application to milling cutters of different diameters.

[0031] The protection component 2 further includes an outer ring member 206 and a clamping rod 207. The outer ring member 206 is slidably connected to the outer peripheral wall of the cylinder 201. The clamping rod 207 is slidably connected inside the connecting member 2051, and the clamping rod 207 penetrates through the upper and lower ends of the connecting member 2051.

[0032] Multiple groups of clamping grooves 2012 are provided at both the upper and lower ends of the chute 2011, and the clamping rod 207 is inserted into the clamping grooves 2012.

[0033] The outer ring member 206 is fixedly connected to the end of the connecting member 2051. A round block 208 penetrates through the side wall of the outer ring member 206. The end of the round block 208 is fixedly connected with a trapezoidal plate 2081. The trapezoidal plate 2081 is slidably connected inside the connecting member 2051. The clamping rod 207 is slidably connected to both sides of the trapezoidal plate 2081. By pressing the round block 208, the trapezoidal plate 2081 can be driven to move towards the inner ring member 205, and the two clamping rods 207 can be driven to slide and contract inside the connecting member 2051. At this time, the inner ring member 205 can be moved through the outer ring member 206.

The two ends of the spring 2082 are fixedly connected to the side wall of the circular block 208 and the inside of the outer ring member 206 respectively. After releasing the circular block 208, the pulling force of the spring 2082 can reset the circular block 208 and the trapezoidal plate 2081 to the right. At the same time, the trapezoidal plate 2081 will squeeze the two sets of clamping rods 207 to the upper and lower sides. At this time, the clamping rods 207 will be inserted into the clamping grooves 2012 of the sliding grooves 2011 in sequence to fix the outer ring member 206 and the outer ring member 206.

[0035] When the utility model is in use, first install the milling cutter on the power milling head 1, then rotatably connect the cylinder 201 to the side wall of the power milling head 1. Secondly, press the circular block 208 to move the trapezoidal plate 2081 towards the inner ring member 205, and drive the two sets of clamping rods 207 to slide and contract inside the connecting member 2051. At this time, the outer ring member 206 and the inner ring member 205 can be moved outwards. The inner ring member 205 can drive the movable rod 203 to move. At the same time, the movable rod 203 can push the support rod 202 to rotate and drive the flexible waterproof cloth 204 to be folded into a horn shape, so that the flexible waterproof cloth 204 is close to the outer peripheral wall of the milling cutter. Then release the circular block 208. The pulling force of the spring 2082 can reset the trapezoidal plate 2081 and the clamping rods 207. At this time, the clamping rods 207 will be inserted into the clamping grooves 2012 of the sliding grooves 2011 in sequence to fix the outer ring member 206 and the outer ring member 206. Finally, drive the milling cutter through the power milling head 1 to mill the fuel injection pump body, and that's it.
