Description

Technical Field

[0001] This utility model relates to the technical field of deep hole grinding equipment, and in particular to processing equipment for deep hole grinding of marine diesel engine parts. Background Technology

[0002] Marine diesel engines are one of the core pieces of equipment on ships, mainly responsible for the ship's main power and power generation tasks. Before assembly, the pipelines used in the intake, oil intake and exhaust systems of diesel engines need to be processed and polished using deep hole grinding equipment.

[0003] When using deep hole grinding equipment to polish the inside of diesel engine pipes, a clamping device is needed to hold the pipes. Then, the rotating rod and grinding head of the grinding equipment are inserted into the pipes for grinding. Because the grinding rod is quite long, the angle of the grinding rod may deviate when the grinding head is rotated by the grinding rod, causing the grinding rod and grinding head to shake when rotating, which affects the grinding effect. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the angle of the grinding rod may deviate when the grinding head is rotated by the long grinding rod, which causes the grinding rod and grinding head to shake when rotating, thus affecting the grinding effect. Therefore, this invention provides a processing equipment for deep hole grinding of marine diesel engine parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a deep-hole grinding processing equipment for marine diesel engine parts, comprising a housing and a shaft, wherein a motor for driving the shaft to rotate is installed inside the housing, the output end of the motor is fixedly connected to one end of the shaft, one end of the shaft rotates on one end of the inner wall of the housing, a grinding head for grinding the inside of the parts is fixedly connected to one end of the shaft, a power cord is provided at one end of the housing, and a positioning device for supporting and positioning the rotating shaft is provided on one side of the housing.

[0006] The effect achieved by the above components is as follows: when using deep hole grinding equipment to grind the inside of the diesel engine pipeline, the pipeline is fixed in position by clamping equipment, and then one end of the grinding head is inserted into the pipeline. The motor inside the operating housing drives the shaft to rotate, and the grinding head at one end of the shaft grinds the inner wall of the pipeline.

[0007] Preferably, the positioning device includes two grooved rods, one end of each grooved rod is fixedly connected to one side of the housing, and sliding rods are slidably connected to the inner walls of the two grooved rods respectively. A rectangular frame is fixedly connected to the end of each sliding rod away from the grooved rod, and several rectangular rods are fixedly connected to the inner walls of the four corners of the rectangular frame. Rollers are rotatably connected to the side of the two rectangular rods that are close to each other.

[0008] The effect achieved by the above components is as follows: When grinding the inside of the diesel engine pipeline using a deep hole grinding device with rollers, the pipeline is fixed in position by a clamping device. Then, one end of the grinding head is inserted into the pipeline, and two sliding rods are pushed to slide on the inner wall of the groove rod towards the grinding head, so that the outer surface of the shaft contacts the outer surface of each roller on the inner wall of the rectangular frame. Then, the power cord at one end of the engine housing is connected to the power supply, and the motor inside the engine housing drives the shaft to rotate. The grinding head at one end of the shaft grinds the inner wall of the pipeline. When the shaft rotates, it will rotate on the outer surface of each roller on the inner wall of the rectangular frame. The angle between the shaft and the engine housing is limited by the rollers and the rectangular frame. During the grinding process, the overall movement of the engine housing and shaft is controlled to adjust the position of the grinding head inside the pipeline. At the same time, the two sliding rods are pushed or pulled to control the movement of the rectangular frame and adjust the position of the rectangular frame in real time according to the length of the shaft inside the pipeline.

[0009] Preferably, one end of the groove rod is fixedly connected to a support rod, and the end of the support rod away from the groove rod is fixedly connected to one side of the machine housing, with the support rod and the groove rod forming a certain angle.

[0010] The effect achieved by the above components is that the support rod can support the bottom of the groove rod, thereby improving the structural stability of the connection between the groove rod and the housing.

[0011] Preferably, one side of the sliding rod is provided with an auxiliary component that can further restrict the position of the sliding rod inside the groove rod. The auxiliary component includes an elastic metal rod, which is an L-shaped bent rod. A rubber sheet is fixedly connected to the bent part of the outer surface of the elastic metal rod, and the rubber sheet at the bent part of the outer surface of the elastic metal rod is in contact with one side of the outer surface of the groove rod.

[0012] The effect achieved by the above components is as follows: when controlling the movement of the sliding rod, one end of the elastic metal rod can be pinched and the elastic metal rod can be bent outward to make the rubber sheet on the outer surface of the elastic metal rod move away from the outer surface of the groove rod, making it easier to pull the sliding rod to move. After releasing the elastic metal rod, the elastic metal rod returns to its original shape and the rubber sheet at the bend will press against the outer surface of the groove rod, further restricting the relative position between the sliding rod and the groove rod, and improving the stability when using the positioning device.

[0013] Preferably, one end of the elastic metal rod is fixedly connected to a groove block, and a groove is formed on one side of the groove block.

[0014] The effect achieved by the above components is that pinching the groove on the outer surface of the slot block makes it easier to pull the elastic metal rod and control its deflection.

[0015] Preferably, a storage device is provided on one side of the housing. The storage device includes a groove cylinder, a round rod is slidably connected to the inner wall of the groove cylinder, a positioning rod is fixedly connected to one end of the round rod, a spring is provided at one end of the round rod, and the two ends of the spring are fixedly connected to one end of the round rod and one end of the inner wall of the groove cylinder, respectively. A top block is fixedly connected to one side of the groove cylinder.

[0016] The effect achieved by the above-mentioned components is as follows: when the deep hole grinding equipment is not used, the round rod can be pulled outward to control the round rod to slide outward on the inner wall of the groove and lengthen the spring. Then, the power cord can be wound around the outer surface of the positioning rod. After that, the positioning rod is released and the spring returns to its original shape, pulling the positioning rod towards the top block to lock the wound power cord between the positioning rod and the top block, thus storing and fixing the power cord and improving the convenience when using the deep hole grinding equipment.

[0017] Preferably, an auxiliary rod is fixedly connected to one side of the top block, and the auxiliary rod is a rubber rod made of rubber.

[0018] The effect achieved by the above components is that by setting the rubber auxiliary rod, the power cord is less likely to slip when it is stuck between the positioning rod and the top block, and the surface of the power cord is less likely to be worn.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] In this invention, by setting a positioning device, when using a deep hole grinding device to grind the inside of the diesel engine pipeline, the sliding rod is pushed to slide on the inner wall of the groove rod to adjust the horizontal position of the sliding rod and the rectangular frame, so that the outer surface of the shaft rod contacts the outer surface of each roller on the inner wall of the rectangular frame. When the shaft rod rotates, it will rotate on the outer surface of each roller. The angle between the shaft rod and the engine housing is limited by the rollers and the rectangular frame, so as to avoid the angle of the shaft rod from deviating as much as possible.

[0027] Example 1, as Figure 1-2 As shown, a deep-hole grinding processing device for marine diesel engine parts includes a housing 1 and a shaft 5. The housing 1 houses a motor for driving the shaft 5 to rotate. The output end of the motor is fixedly connected to one end of the shaft 5. One end of the shaft 5 rotates on the inner wall of the housing 1. A grinding head 6 for grinding the inside of the parts is fixedly connected to one end of the shaft 5. A power cord 4 is installed at one end of the housing 1. A positioning device 2 for supporting and positioning the rotating shaft 5 is installed on one side of the housing 1. When using the deep-hole grinding device to grind the inside of the diesel engine's pipeline, the pipeline is fixed in position using a clamping device. Then, one end of the grinding head 6 is inserted into the pipeline. The motor inside the housing 1 drives the shaft 5 to rotate, and the grinding head 6 at one end of the shaft 5 grinds the inner wall of the pipeline.

[0028] Reference Figure 2-4As shown in this embodiment: the positioning device 2 includes two grooved rods 21. One end of each grooved rod 21 is fixedly connected to one side of the housing 1. Sliding rods 22 are slidably connected to the inner walls of the two grooved rods 21 respectively. A rectangular frame 23 is fixedly connected to the end of each sliding rod 22 away from the grooved rod 21. Several rectangular rods 24 are fixedly connected to the inner walls of the four corners of the rectangular frame 23. Rollers 25 are rotatably connected to the side of the two rectangular rods 24 that are close to each other. By setting the rollers 25, when using a deep hole grinding device to grind the inside of the diesel engine's pipeline, the pipeline is fixed in position by a clamping device. Then, one end of the grinding head 6 is inserted into the pipeline, and the two sliding rods 22 are pushed to slide on the inner wall of the grooved rod 21 toward the grinding head 6, so that the outer surface of the shaft 5 contacts the outer surface of each roller 25 on the inner wall of the rectangular frame 23. Then, the power cord 4 at one end of the housing 1 is connected to the power supply, and the motor inside the housing 1 drives the shaft 5 to rotate. The grinding head at one end of the shaft 5 rotates through the power cord 22. 6. Grinding the inner wall of the pipeline. When the shaft 5 rotates, it will rotate on the outer surface of each roller 25 on the inner wall of the rectangular frame 23. The angle between the shaft 5 and the housing 1 is limited by the rollers 25 and the rectangular frame 23. During the grinding process, the housing 1 and the shaft 5 are moved as a whole to adjust the position of the grinding head 6 inside the pipeline. At the same time, the two sliding rods 22 are pushed or pulled to control the movement of the rectangular frame 23. The position of the rectangular frame 23 is adjusted in real time according to the length of the shaft 5 inside the pipeline. By setting the positioning device 2, when grinding the inside of the diesel engine pipeline with the deep hole grinding equipment, the sliding rod 22 is pushed to slide on the inner wall of the groove rod 21 to adjust the horizontal position of the sliding rod 22 and the rectangular frame 23, so that the outer surface of the shaft 5 contacts the outer surface of each roller 25 on the inner wall of the rectangular frame 23. When the shaft 5 rotates, it will rotate on the outer surface of each roller 25. The angle between the shaft 5 and the housing 1 is limited by the rollers 25 and the rectangular frame 23 to avoid the angle of the shaft 5 from deviating as much as possible.

[0029] Reference Figure 2-4 As shown in this embodiment: one end of the groove rod 21 is fixedly connected to a support rod 26, and the end of the support rod 26 away from the groove rod 21 is fixedly connected to one side of the housing 1. The support rod 26 and the groove rod 21 form a certain angle. By setting the support rod 26, the lower part of the groove rod 21 can be supported, thereby improving the structural stability of the connection between the groove rod 21 and the housing 1.

[0030] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5As shown in this embodiment: an auxiliary component 27 is provided on one side of the sliding rod 22 to further restrict the position of the sliding rod 22 inside the groove rod 21. The auxiliary component 27 includes an elastic metal rod 271, which is an L-shaped bent rod. A rubber sheet 272 is fixedly connected to the bent part of the outer surface of the elastic metal rod 271. The rubber sheet 272 at the bent part of the outer surface of the elastic metal rod 271 contacts one side of the outer surface of the groove rod 21. When controlling the movement of the sliding rod 22, one end of the elastic metal rod 271 can be pinched and the elastic metal rod 271 can be bent outward to make the outer surface of the elastic metal rod 271... The rubber sheet 272 is away from the outer surface of the groove rod 21, which makes it easier to pull the sliding rod 22 to move. After the elastic metal rod 271 is released, the elastic metal rod 271 returns to its original shape and presses the rubber sheet 272 at the bent part against the outer surface of the groove rod 21, which further restricts the relative position between the sliding rod 22 and the groove rod 21 and improves the stability when using the positioning device 2. One end of the elastic metal rod 271 is fixedly connected to the groove block 273. A groove is opened on one side of the groove block 273. Pinching the groove on the outer surface of the groove block 273 makes it easier to pull the elastic metal rod 271 and control the deflection of the elastic metal rod 271.

[0031] Reference Figure 2 , Figure 4 and Figure 5 As shown in this embodiment: a storage device 3 is provided on one side of the housing 1. The storage device 3 includes a groove 31. A round rod 32 is slidably connected to the inner wall of the groove 31. A positioning rod 34 is fixedly connected to one end of the round rod 32. A spring 33 is provided at one end of the round rod 32. The two ends of the spring 33 are fixedly connected to one end of the round rod 32 and one end of the inner wall of the groove 31, respectively. A top block 35 is fixedly connected to one side of the groove 31. When the deep hole grinding equipment is not used, the round rod 32 can be pulled outward to control the round rod 32 to slide outward on the inner wall of the groove 31 and stretch the spring 33. Then the power cord 4 is wound around the groove 31. The power cord 4 is wrapped around the outer surface of the positioning rod 34, and then the positioning rod 34 is released. The spring 33 restores the original shape and pulls the positioning rod 34 towards the top block 35, thus securing the wrapped power cord 4 between the positioning rod 34 and the top block 35. This improves the convenience of using deep hole grinding equipment. An auxiliary rod 36 is fixedly connected to one side of the top block 35. The auxiliary rod 36 is made of rubber. By setting the rubber auxiliary rod 36, the power cord 4 is less likely to slip when it is secured between the positioning rod 34 and the top block 35, and it is less likely to cause wear on the surface of the power cord 4.

[0032] Working principle: When using a deep hole grinding device to grind the inside of a diesel engine pipeline, the pipeline is fixed in position using a clamping device. Then, one end of the grinding head 6 is inserted into the pipeline. Two sliding rods 22 are pushed, causing them to slide along the inner wall of the groove rod 21 towards the grinding head 6, making the outer surface of the shaft 5 contact the outer surfaces of the rollers 25 on the inner wall of the rectangular frame 23. The power cord 4 at one end of the housing 1 is then connected to a power source, and the motor inside the housing 1 drives the shaft 5 to rotate. The grinding head 6 at one end of the shaft 5 grinds the inner wall of the pipeline. As the shaft 5 rotates, it rotates on the outer surfaces of the rollers 25 on the inner wall of the rectangular frame 23. The rollers 25 and the rectangular frame 23 limit the angle between the shaft 5 and the housing 1. During the grinding process, the overall movement of the housing 1 and the shaft 5 is controlled to adjust the position of the grinding head 6 inside the pipeline. Simultaneously, one end of the elastic metal rod 271 is pinched and pulled outwards. The elastic metal rod 271 moves the rubber sheet 272 on its outer surface away from the outer surface of the groove rod 21, facilitating the movement of the sliding rod 22 and controlling the movement of the rectangular frame 23. The position of the rectangular frame 23 is adjusted in real time according to the length of the shaft 5 inside the pipeline. After the elastic metal rod 271 is released, it returns to its original shape and presses the rubber sheet 272 at the bend against the outer surface of the groove rod 21, further restricting the relative position between the sliding rod 22 and the groove rod 21. When the deep hole grinding equipment is not used, the round rod 32 can be pulled outward to control the round rod 32 to slide outward on the inner wall of the groove cylinder 31 and lengthen the spring 33. Then, the power cord 4 is wrapped around the outer surface of the positioning rod 34. After that, the positioning rod 34 is released and the spring 33 returns to its original shape, pulling the positioning rod 34 towards the top block 35 to lock the wrapped power cord 4 between the positioning rod 34 and the top block 35, thus storing and fixing the power cord 4.
