Description

Technical Field

[0001] This utility model relates to the field of plunger sleeve processing technology, and in particular to a plunger sleeve drilling and reaming processing device. Background Technology

[0002] Drilling and reaming of plunger sleeves is a machining process used to manufacture high-precision plunger sleeve inner bores, primarily applied to critical components such as hydraulic pumps and fuel injection systems. As a precision-fitting part, the dimensional accuracy, roundness, and surface roughness of the plunger sleeve's inner bore directly affect sealing performance and motion characteristics; therefore, drilling and reaming processes are essential to ensure quality. A high-precision reamer is used to finish the pre-drilled hole, removing trace amounts of material and correcting hole shape errors to ultimately achieve IT6-IT7 tolerance requirements. A suitable cutting fluid must be selected during reaming to reduce thermal deformation and improve surface finish.

[0003] Current plunger sleeve reaming devices generate metal shavings during actual use. As the reaming drill bit rotates, these shavings and cutting fluid splash everywhere. The existing plunger sleeve lacks a structure to block the cutting fluid and shavings, resulting in a dirty surface of the device and making subsequent cleaning inconvenient. Therefore, in order to address the above-mentioned shortcomings, this utility model proposes a plunger sleeve drilling and reaming device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and to propose a plunger sleeve drilling and reaming device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plunger sleeve drilling and reaming device, comprising a base plate, a vertical plate fixed on one side of the upper surface of the base plate, and a three-jaw chuck fixedly installed on the surface of the vertical plate; an L-shaped plate fixed on the other side of the upper surface of the base plate; a linear motor horizontally fixed on the top of the L-shaped plate; a drive motor fixed on the lower surface of the moving end of the linear motor; a spindle fixed on the output end of the drive motor; a drill bit fixed on the other end of the spindle; a splash guard slidably sleeved on the outside of the spindle; a nozzle fixed inside the top of the splash guard; a fluid reservoir for storing cutting fluid provided on the upper surface of the base plate and below the splash guard; a pump body connecting the fluid reservoir and the nozzle installed on the upper surface of the base plate; and a filter assembly installed on the top of the fluid reservoir.

[0006] Furthermore, the drill bit is located inside the splash guard, which has an open design on the side near the three-jaw chuck. A through hole is provided in the middle of the splash guard near the drive motor, through which the spindle passes and is slidably connected. A strip-shaped opening is provided on the bottom wall of the splash guard.

[0007] Furthermore, a side plate is fixed to the outer wall of the drive motor near the splash guard, and a spring is fixedly connected between the side plate and the splash guard.

[0008] Furthermore, the pump body inlet is connected to the liquid storage box via a pipe, and a flexible hose is fixedly connected between the pump body outlet and the nozzle.

[0009] Furthermore, the filter assembly includes a U-shaped plate sleeved on the top surface of the liquid storage box, a support frame fixed to the inner side wall of the U-shaped plate, and a filter screen fixed inside the support frame, with the lower surface of the support frame in contact with the top of the liquid storage box.

[0010] Furthermore, handles are fixed on both sides of the outer wall of the spiral plate.

[0011] The beneficial effects of this utility model are:

[0012] 1. In use, this utility model is a plunger sleeve drilling and reaming processing device, which includes a base plate, a three-jaw chuck, an L-shaped plate, a linear motor, a drive motor, a drill bit, a splash guard, a liquid storage box, a pump body, and a nozzle. After the plunger sleeve is fixed by the three-jaw chuck, the linear motor drives the drive motor to move, thereby processing the plunger sleeve by rotating the drill bit. During processing, the pump body draws out the cutting fluid from the liquid storage box and sprays it onto the surface of the plunger sleeve through the nozzle. The debris and cutting fluid generated during processing are always blocked by the splash guard to avoid splashing debris and cutting fluid and to ensure the cleanliness of the device surface.

[0013] 2. When in use, this utility model is a plunger sleeve drilling and reaming device, which is equipped with a splash guard, a liquid storage box and a filter assembly. The debris and cutting fluid blocked by the splash guard will fall from the bottom strip-shaped opening of the splash guard into the liquid storage box. The cutting fluid can be reused by the filtration of the filter assembly, and the debris can be collected in a concentrated manner. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] As shown in Figures 1-3, a plunger sleeve drilling and reaming device is disclosed, comprising a base plate 1, a vertical plate 2 fixed on one side of the upper surface of the base plate 1, and a three-jaw chuck 3 fixedly mounted on the surface of the vertical plate 2; an L-shaped plate 4 fixed on the other side of the upper surface of the base plate 1; a linear motor 5 horizontally fixed on the top of the L-shaped plate 4; a drive motor 6 fixed on the lower surface of the moving end of the linear motor 5; a spindle 7 fixed on the output end of the drive motor 6; a drill bit 8 fixed on the other end of the spindle 7; a splash guard 9 slidably sleeved on the outside of the spindle 7; a nozzle 10 fixed inside the top of the splash guard 9; a fluid reservoir 11 for storing cutting fluid provided on the upper surface of the base plate 1 and below the splash guard 9; a pump body 12 connecting the fluid reservoir 11 and the nozzle 10 mounted on the upper surface of the base plate 1; and a filter assembly 14 mounted on the top of the fluid reservoir 11.

[0022] The drill bit 8 is located inside the splash guard 9. The splash guard 9 has an open design on the side near the three-jaw chuck 3. A through hole is opened in the middle of the end of the splash guard 9 near the drive motor 6. The spindle 7 passes through the through hole and is slidably connected to the through hole. A strip-shaped opening 91 is opened on the bottom wall of the splash guard 9.

[0023] The drive motor 6 rotates the drill bit 8, and the chips generated during the machining of the plunger sleeve are blocked by the splash guard 9 on the outside. Furthermore, the cutting fluid sprayed from the nozzle 10 is also blocked by the splash guard 9, preventing chips and...

[0024] The cutting fluid splashes everywhere, and the blocked debris and cutting fluid slide down the inner wall of the splash guard 9, then exit from the bottom strip 91, and finally fall into the filter assembly 14.

[0025] A side plate 61 is fixed to the outer side wall of the drive motor 6 near the splash guard 9, and a spring 92 is fixedly connected between the side plate 61 and the splash guard 9.

[0026] When the linear motor 5 drives the drive motor 6 to move laterally and the drill bit 8 processes the plunger sleeve, the splash guard 9 will move along with it. When the splash guard 9 contacts the three-jaw chuck 3, since the splash guard 9 is slidably connected to the spindle 7, the splash guard 9 will not affect the continued movement of the drive motor 6, the spindle 7 and the drill bit 8. As the drill bit 8 continues to move, the spring 92 will be compressed. When the drive motor 6 moves away from the three-jaw chuck 3, the spring 92 will return to its original position, pushing the splash guard 9 to always be located outside the drill bit 8.

[0027] The pump body 12 inlet is connected to the liquid storage box 11 through a pipe, and the pump body 12 outlet is fixedly connected to the nozzle 10 by a hose 13.

[0028] The pump body 12 can extract the cutting fluid from the reservoir 11, then input it into the nozzle 10 through the hose 13, and finally spray it out from the nozzle 10.

[0029] The filter assembly 14 includes a U-shaped plate 141 sleeved on the top surface of the liquid storage box 11. A support frame 142 is fixed to the inner side wall of the U-shaped plate 141, and a filter screen 143 is fixed inside the support frame 142. The lower surface of the support frame 142 is in contact with the top of the liquid storage box 11.

[0030] The U-shaped plate 141 is directly slidably fitted onto the top of the liquid reservoir 11, making its installation and removal simple and convenient. Cutting fluid and debris discharged from the bottom of the splash guard 9 fall into the U-shaped plate 141 and are filtered by the filter screen 143. The filtered cutting fluid then returns to the liquid reservoir 11. After each use, the U-shaped plate 141 is removed from the top of the liquid reservoir 11, and the debris on the surface of the filter screen 143 is cleaned.

[0031] Handles 144 are fixed on both sides of the outer wall of the U-shaped plate 141.

[0032] The handle 144 makes it easy to lift the spiral plate 141.

[0033] Working principle: First, the plunger sleeve is fixed by the three-jaw chuck 3. Then, the drive motor 6 is started to drive the drill bit 8 to rotate. Next, the linear motor 5 drives the drive motor 6 to move towards the plunger sleeve. The drill bit 8 is used to process the plunger sleeve. During this process, the splash guard 9 will first contact the three-jaw chuck 3, so that the splash guard 9...

[0034] The cutting fluid is always fitted onto the surfaces of the plunger sleeve, drill bit 8, and three-jaw chuck 3. During machining, the pump body 12 is activated to extract the cutting fluid from the reservoir 11. The nozzle 10 is used to spray lubricant onto the drill bit 8. The machining debris and sprayed cutting fluid slide down the inner wall of the splash guard 9 and finally fall into the filter assembly 14 through the strip 91. The cutting fluid filtered through the filter screen 143 returns to the reservoir 11 for reuse.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
