Description

Technical Field

[0001] The utility model belongs to the technical field of crankshaft processing, and particularly relates to a punching device for a crankshaft. Background Technique

[0002] The crankshaft is an important component on the engine. The rotation of the crankshaft is the power source of the engine and also the power source of the entire mechanical system. The crankshaft is widely used in the automotive industry. During the processing of the crankshaft, it is necessary to punch holes in the crankshaft.

[0003] Chinese Patent Publication No. CN212599075U discloses a two-way punching device for a crankshaft, including a device body and a first hydraulic telescopic rod. A first motor is arranged on the left side of the device body, and the first motor is connected to a first rotating shaft. The first rotating shaft penetrates the left side wall of the device body and is connected to a lead screw, and the lead screw is rotatably connected to the inner side of the device body. At the same time, a punching mechanism frame is penetrated through the lead screw. The first hydraulic telescopic rod is arranged on the device body. The lower end of the sliding table is connected to a slide rail, and a second hydraulic telescopic rod is arranged on the upper end surface of the sliding table. The inner side wall of the support table is rotatably connected to a hydraulic clamp. The second rotating shaft penetrates the right inner side wall of the support table and is connected to a second motor, and the second motor is arranged on the right side of the support table. For this two-way punching device for a crankshaft, under the action of the first motor, the lead screw is driven to rotate by the first rotating shaft, so that the two punching mechanism frames move to both sides respectively to punch holes in the crankshaft, improving the processing efficiency of the crankshaft.

[0004] In view of the above related technologies, the inventor found that at least the following problems exist in this technology: By setting a first through-port groove and a second through-port groove, the waste chips generated during punching automatically fall into the collection box. However, during the high-speed rotation of the drill bit, the waste chips on the surface of the crankshaft will splash randomly in all directions. Therefore, it is difficult to ensure that all waste chips enter the collection box through the first through-port groove and the second through-port groove. Some waste chips will splash and remain on the surface of the device body, requiring manual cleaning later, which is not convenient for personnel to recycle and collect. Moreover, during the long-term high-speed rotation and use of the drill bit, the surface temperature gradually increases, thereby reducing the service life of the drill bit. Therefore, we provide a punching device for a crankshaft to improve the effect of waste chip recovery, avoid waste chips from splashing and remaining on the surface of the device body randomly, and at the same time, ensure the service life of the drill bit.

A water pump is fixedly installed outside the water storage tank, and the water pump is connected to a branch pipe through a water guide pipe, and the branch pipe is fixed on the surface of the baffle. Connecting hoses are fixedly connected to both ends of the branch pipe, and the end of the connecting hose is fixedly connected to the water sprayer. A hydraulic clamp is arranged inside the baffle.

[0007] As a preferred embodiment, a chute is provided on one side of the workbench, the movable frame is slidably arranged inside the chute, and a handle is fixedly connected to one side of the movable frame.

[0008] As a preferred embodiment, a perspective window is fixedly connected inside the movable plate.

[0009] As a preferred embodiment, a guide rail is fixedly installed at the upper end of the workbench, a movable seat is slidably arranged inside the guide rail, and the support frame is fixed on the upper surface of the movable seat. A bidirectional lead screw is rotatably arranged inside the fixed groove, and the movable seat is threadedly connected to both ends of the bidirectional lead screw.

[0010] As a preferred embodiment, a lead screw is rotatably arranged inside the guide rail, and the movable seat is threadedly connected to the lead screw.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] 1. When the utility model is in use, the crankshaft is fixed in the baffle by a hydraulic clamp. Then, by moving the moving plate on the sliding rail, an opening in the baffle is blocked. The cylinder pushes the machine box downward, and the drill rotates to perform the opening operation on the crankshaft. During the opening process, the water pump extracts the water source from the water storage tank, guides it through the water pipe to the branch pipe, and then through the connecting hose to the sprinkler for spraying. The opening of the sprinkler faces the drill. When the drill is drilling the crankshaft, the sprinkler sprays water flow onto the surface of the drill and the crankshaft, thereby cooling the drill. At the same time, the water flow takes away the waste chips and flows towards the moving frame. The waste chips can be filtered through the filter screen in the moving frame. Some waste chips splash onto the surface of the baffle along with the water flow. At this time, another water pump diverts the water source through the water pipe to the fixed seat, and sprays it onto the surface of the baffle through the nozzle at the lower end of the fixed seat, so that the waste chips attached to the surface of the baffle can be washed towards the moving frame, thus avoiding the waste chips remaining on the surface of the baffle, making all the waste chips flow onto the surface of the filter screen, and the water flow passes through the filter screen and returns to the water storage tank for secondary use. In this way, the recovery effect of the waste chips can be ensured, and the waste chips can be prevented from remaining on the workbench or the surface of the baffle. At the same time, the sprinkler sprays water flow to cool the drill, which can ensure the service life of the drill.

[0014] 2. When the processing of the crankshaft is completed and the waste chips need to be cleaned and recycled, the staff can pull out the moving frame from the sliding groove through the handle on one side of the moving frame, which is convenient for the staff to recycle the waste chips later and is also convenient for disassembling and assembling the moving frame.

[0027] In this embodiment, a fixed seat 8 is fixedly connected to the inner surface of the baffle 6, and a nozzle 801 is fixedly arranged at the lower end of the fixed seat 8. The fixed seats 8 are connected through a connecting pipe 9. Two water pumps 11 are fixedly installed on the outer side of the water storage tank 10.

[0028] Working principle and usage process of the utility model: When in use, the crankshaft to be drilled is fixed in the baffle 6 through the hydraulic clamp 7. Then, the moving plate 5 is pulled to close the opening on one side of the baffle 6. When drilling, the motor 28 drives the lead screw 25 to rotate, causing the movable seat 26 to move within the guide rail 24, thereby driving the support frame 27 and the fixed frame 15 to move, adjusting the longitudinal position of the drill bit 21. Moreover, in cooperation with the rotation of the bidirectional lead screw 17 within the fixed frame 15, the moving seats 18 threadedly connected to both sides of the bidirectional lead screw 17 move along the fixed groove 16.

The water sprayer 23 sprays water onto the surfaces of the drill bit 21 and the crankshaft, which can cool the drill bit 21. And the waste chips generated during drilling flow with the water to the moving frame 3. The waste chips contained in the water flow are filtered by the filter screen 301. Part of the water flow and waste chips are splashed onto the surface of the baffle 6 under the influence of the rotation of the drill bit 21. At this time, the other water pump 11 guides the water flow through the water pipe 12 to the fixed seat 8, and sprays it onto the surface of the baffle 6 through the nozzle 801 at the lower end of the fixed seat 8, thus flushing the waste chips on the surface of the baffle 6. The waste chips flow with the water to the moving frame 3, thereby improving the recovery effect of the waste chips and avoiding the residue of waste chips that need to be manually cleaned later;

[0030] When recovering the waste chips, the staff can pull out the moving frame 3 from the sliding groove 2 through the handle on one side of the moving frame 3, which is convenient for the staff to recover the waste chips later and is also convenient for disassembling and assembling the moving frame 3.
