Description

Technical Field

[0001] This utility model relates to the field of drilling technology for cam bearing washers, and specifically to a drilling machine for machining cam bearing washers. Background Technology

[0002] Cam bearing washers are key components in mechanical equipment such as engines. They typically need to withstand large loads and friction. Cam bearing washers usually have holes for installation and fixation, and these holes need to be precisely drilled using a drilling machine.

[0003] In the existing processing of cam bearing washers, the high-speed rotation of the drilling machine causes the drill bit temperature to rise. Under high temperature, the drill bit is prone to deformation, which accelerates wear. For example, the metal washer drilling processing device disclosed in CN220050105U uses a drill spindle to drill metal washers. However, the high-speed rotating drill spindle generates a lot of heat during the drilling process. If there is no effective cooling mechanism, the drill spindle will not only soften due to high temperature and deform, but the hardness and sharpness of the drill bit will also decrease under high temperature, resulting in increased surface roughness of the drilled hole and even possible hole diameter deviation. Because the drill bit is prone to deformation and wear, it needs to be replaced frequently, thereby reducing production efficiency.

[0004] Therefore, it is necessary to invent a drilling machine for machining cam bearing washers to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a drilling machine for machining cam bearing washers, so as to solve the problem of cooling high-temperature drill bits that do not have a cooling function in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drilling machine for processing cam bearing washers, comprising a machine body and a nozzle. Vertical plates are provided on both sides of the upper part of the machine body, and a crossbeam is mounted on the vertical plates. A movable seat is provided on the front wall of the crossbeam, and a motor mounting plate is provided on the front wall of the movable seat. A servo motor is mounted on the front wall of the motor mounting plate, and a drill bit is connected to the output end of the servo motor. A worktable and a fixed plate are provided below the drill bit. A through groove is opened on the worktable and extends to the bottom of the fixed plate. A collection groove is provided directly below the through groove. A water tank is provided on the rear side of the machine body, and a water pump is provided above the water tank. The inlet end of the water pump is connected to the outlet end of the water tank, and a water injection pipe is connected to the outlet end of the water pump. A portion of the water injection pipe is provided with a corrugated pipe, and a nozzle is provided at the output end of the water injection pipe.

[0007] Preferably, an X-axis transmission assembly is provided between the crossbeam and the movable seat, and the crossbeam and the movable seat transmit driving force through the X-axis transmission assembly in order to realize the horizontal movement of the drill bit.

[0008] Preferably, a Y-axis transmission assembly is provided between the movable base and the motor mounting plate, and the movable base and the motor mounting plate transmit driving force through the Y-axis transmission assembly to realize the vertical movement of the drill bit.

[0009] Preferably, the fixing plate is located directly below the worktable and is mounted on the machine body by four screws, providing a stable support surface for fixing and supporting the worktable.

[0010] Preferably, clamping plates are provided on the left and right sides above the worktable, and an electric push rod is provided on one side of the clamping plate. The output end of the electric push rod is connected to the side wall of the clamping plate to realize the clamping operation of the workpiece.

[0011] Preferably, the collection trough is located inside the machine body and has a funnel-shaped structure design to facilitate the collection of waste materials and cooling water generated during the processing.

[0012] Preferably, a transparent observation window is provided on one side wall of the water tank, which allows the operator to observe the water level in the tank at any time and to replenish the water in a timely manner.

[0013] Preferably, two nozzles are provided, located on the left and right sides of the drill bit, to achieve spray cooling of the drill bit.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model forms a complete cooling system by setting a water tank on the rear side of the machine body and connecting it with a water pump and water injection pipe, along with a corrugated pipe and nozzles. In particular, the two nozzles are located on the left and right sides of the drill bit. This layout ensures that the cooling water can be sprayed evenly and fully onto the drill bit. The coolant can effectively reduce the heat generated by the drill bit during high-speed rotation and drilling, reduce thermal wear, and thus extend the service life of the drill bit.

[0016] 2. This utility model, through the through groove opened on the workbench and the funnel-shaped collection trough located inside the machine body, together constitutes an efficient waste and cooling water collection system. The debris generated during drilling and the sprayed cooling water fall directly into the collection trough through the through groove, avoiding pollution and water accumulation in the work area, maintaining the cleanliness of the work environment, and enabling the waste and cooling water to be collected in a concentrated manner, which facilitates subsequent cleaning and treatment work and reduces the labor intensity of operators.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-6 The drilling machine shown includes a machine body 1 and a nozzle 19. Vertical plates 2 are arranged on both sides of the upper part of the machine body 1. A crossbeam 3 is mounted on the vertical plates 2. A movable seat 4 is arranged on the front wall of the crossbeam 3. A motor mounting plate is arranged on the front wall of the movable seat 4, and a servo motor 6 is mounted on the front wall of the motor mounting plate. A drill bit 8 is connected to the output end of the servo motor 6. A worktable 10 and a fixed plate 9 are arranged below the drill bit 8. A through groove 11 is opened on the worktable 10 and extends to the bottom of the fixed plate 9. A collection groove 14 is arranged directly below the through groove 11. A water tank 15 is arranged on the rear side of the machine body 1. A water pump 16 is arranged above the water tank 15. The inlet end of the water pump 16 is connected to the outlet end of the water tank 15. A water injection pipe 17 is connected to the outlet end of the water pump 16. A nozzle 19 is arranged at the output end of the water injection pipe 17.

[0027] An X-axis transmission assembly 5 is provided between the crossbeam 3 and the movable seat 4, and the crossbeam 3 and the movable seat 4 transmit driving force through the X-axis transmission assembly 5. A Y-axis transmission assembly 7 is provided between the movable seat 4 and the motor mounting plate, and the movable seat 4 and the motor mounting plate transmit driving force through the Y-axis transmission assembly 7.

[0028] The X-axis transmission assembly 5 is responsible for transmitting driving force in the horizontal X-axis direction, enabling the moving seat 4 to move smoothly along the crossbeam 3. This design ensures the precise positioning and movement of the drill bit 8 in the horizontal direction. The Y-axis transmission assembly 7 is responsible for transmitting driving force in the vertical Y-axis direction, enabling the motor mounting plate and its servo motor 6 and drill bit 8 to move up and down. This design allows the drill bit 8 to precisely control the drilling depth.

[0029] The fixing plate 9 is located directly below the workbench 10. The fixing plate 9 is installed on the machine body 1 by four screws. Clamping plates 13 are provided on the left and right sides above the workbench 10. An electric push rod 12 is provided on one side of the clamping plate 13. The output end of the electric push rod 12 is connected to the side wall of the clamping plate 13.

[0030] The fixed plate 9 and the worktable 10 together form a support platform for processing the workpiece, and the clamping plate 13 driven by the bioelectric push rod 12 can firmly clamp the workpiece to prevent it from moving or deforming during processing, thus ensuring the safety and stability of processing.

[0031] The collection tank 14 is located inside the body 1. The collection tank 14 has a funnel-shaped structure design. A transparent observation window is provided on one side wall of the water tank 15. A corrugated pipe 18 is provided on a part of the water injection pipe 17. There are two nozzles 19, which are located on the left and right sides of the drill bit 8.

[0032] The funnel-shaped collection tank 14 allows waste materials and cooling water generated during processing to flow smoothly into the collection tank 14, facilitating subsequent cleaning and treatment. The transparent observation window design allows operators to directly observe the water level in the water tank 15 without opening the water tank cover. When the water level is too low, the operator can add water in time to ensure the normal operation of the cooling system. The corrugated pipe 18 is flexible, which increases the flexibility and adaptability of the water injection pipe 17 and does not obstruct the movement of the nozzle 19. Thus, the water injection pipe 17 is responsible for injecting cooling water into the nozzle 19, and the nozzle 19 sprays cooling water onto the drill bit 8, effectively reducing the temperature of the drill bit 8, thereby extending the service life of the drill bit 8 and improving processing efficiency.

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual appendix Figure 1-2When using this utility model, first fill the water tank 15 with cooling water, then place the cam bearing washer to be processed on the worktable 10, ensuring that the workpiece is between the two clamping plates 13. Start the electric push rod 12, so that its output end pushes the clamping plate 13 to move inward until the clamping plate 13 firmly clamps the workpiece, ensuring that the workpiece will not move or deform during processing. Then, through the adjustment of the X-axis transmission assembly 5 and the Y-axis transmission assembly 7, the position of the moving seat 4 and the motor mounting plate is precisely controlled, thereby determining the drilling position of the drill bit 8. After confirming that the position of the drill bit 8 is correct, start the servo motor 6, so that it drives the drill bit 8 to start rotating and perform drilling operation on the workpiece.

[0035] Refer to the instruction manual appendix Figure 3-6 When using this utility model, the water pump 16 is started simultaneously, so that cooling water flows into the nozzle 19 through the water injection pipe 17 and the corrugated pipe 18, and sprays cooling water onto the working drill bit 8. The waste material and cooling water generated during the drilling process will flow into the collection tank 14 located inside the machine body 1 through the through groove 11 on the workbench 10. Before starting the equipment, a movable waste box can be placed at the bottom of the collection tank 14 to receive the waste material and cooling water, so as to facilitate subsequent dumping. When the drill bit 8 reaches the predetermined drilling depth, the servo motor 6 stops rotating, and the drill bit 8 rises back to the initial position. At this time, the operator drives the clamping plate 13 away from the workpiece through the electric push rod 12, so that the clamping plate 13 releases the workpiece, and then the processed cam bearing washer can be taken out.
