Description

Technical Field

[0001] The invention belongs to the technical field of hole punching, and in particular relates to a hole punching device for producing a main reducer housing. Background Art

[0002] The main reducer is the main component that reduces the speed and increases the torque in the transmission system. It is composed of an upper and lower housing and multiple gears of different sizes. To ensure the service life of the reducer, its housing is usually cast from a metal housing. Therefore, during the production and assembly process, it is necessary to punch holes in the reducer housing, install the gear parts between the two housings, and then tighten them with bolts. When processing the cast shell, the irregularly shaped reducer shell needs to be fixed vertically first, and the grinding fluid is sprayed on the opening area, and then the drill is driven by a motor to open the hole. The drill will generate metal debris in the process of reciprocating drilling and retracting, and its shape is filamentous or blocky. When these debris are mixed with grinding fluid waste, they will adhere to the outer surface of the track and the inside of the pipeline, making them difficult to clean. Therefore, a hole processing device for the production of main reducer shells that can handle debris is needed. Summary of the invention

When the metal debris is cleaned by vibration, the nozzles on the two symmetrical oblique rods can move to different positions on the oblique rods. When the sliding block is closer to the vertical plate, the height of the nozzle is higher, and the flushing effect of the grinding fluid on the debris is better. When the sliding block moves closer to the table top, the nozzle is closer to the position of the first track, and the surface of the first track can be flushed.

[0014] 3. The present invention is equipped with a material feeding and discharging assembly. The movable frame moves to the right on the second track.

The clamping of the rotating clamping block on the metal shell is released, and the movable frame moves to the left on the second track to complete the discharging, thereby realizing that one mechanical mechanism can complete the material feeding and discharging.

[0019] Working principle: When using the present invention, firstly, the feeding and discharging assembly 6 is driven, the movable frame 62 moves to the right on the second track 61, and the square rod 63 drives the telescopic rod 64 and the clamping hand 65 to pass through the elliptical hole 33. After the metal casting shell to be punched is clamped by the clamping hand 65, the telescopic rod 64 shortens its stroke, and the movable frame 62 moves to the right on the second track 61, and the casting shell is moved to the clamping assembly 3; At this time, a part of the shell will pass through the elliptical hole 33 and be clamped in the elliptical hole 33. At this time, the rotating clamp block 34 is rotated back to its original position to clamp the outer edge of the metal shell that needs to be punched. At this time, the spray assembly 4 is pre-started, and the sliding block 43 moves obliquely on the inclined rod 41, so that the spray head 44 can be aimed at the metal shell to spray the grinding liquid on it; Then start the punching assembly 5, the second motor 55 rotates to drive the drill bit 56 to rotate, the moving block 52 moves to the right on the screw rod 51, and the drill bit 56 makes a hole in the metal shell. The height of the hydraulic rod 53 can be adjusted to adjust the longitudinal position of the drilling hole. The second motor 55 moves in the first track 54 to adjust the lateral position during drilling. The moving block 52 moves on the screw rod 51 to control the drill bit 56 to drill and withdraw the hole. When the drill bit 56 reciprocates in drilling and withdraws, filamentary or block-shaped metal debris will be generated. These debris will be mixed with the waste grinding liquid and fall into the vibrating transport component 2 area under the factor of gravity. At this time, the first motor 23 is started, and the rotation of the first motor 23 drives the eccentric wheel 25 on the outer edge of the rotating shaft 24 to rotate. The multiple eccentric wheels 25 will generate vibration force when rotating. The first crawler 27 elastically connected to the table 12 through the metal spring 21 and the spring 28 will generate a longitudinal vibration force while rotating and transporting obliquely downward.

When cleaning metal debris by vibration, the nozzles 44 on the two symmetrical inclined rods 41 can move to different positions on the inclined rods 41. When the sliding block 43 is closer to the vertical plate 32, the nozzle 44 is at a higher height, and the grinding fluid has a better flushing effect on the debris. When the sliding block 43 moves closer to the table 12, the nozzle 44 is closer to the first crawler 27, and the surface of the first crawler 27 can be flushed. After the processing is completed, the telescopic rod 64 increases the stroke, the clamping hand 65 clamps the metal shell, the rotating clamping block 34 releases the clamping of the metal shell, and the movable frame 62 moves to the left on the second track 61 to complete the material discharge, and the work process ends here.
