Description

Technical Field

[0001] The invention relates to the field of a hole punching machine for machining a bearing seat, and in particular to a hole punching machine for machining a bearing seat. Background Art

[0002] The working principle of a hole punching machine for bearing seat processing usually involves multiple key components and steps. First, the drill bit is driven to rotate by a motor or hydraulic device; second, the feed speed and depth of the drill bit are controlled by the feed mechanism; finally, the drill bit is cooled and lubricated by the cooling and lubrication system to ensure the stability and accuracy of the drilling process. With the rapid development of the manufacturing industry, the processing accuracy and efficiency of mechanical parts such as bearing seats are increasingly required. Traditional drilling methods can no longer meet the needs of modern industry. Therefore, a hole punching machine for bearing seat processing came into being.

[0003] In the prior art, a large amount of heat is generated during the machining process due to the high-speed friction and cutting action between the drill bit and the workpiece. If the heat is not dissipated in time, the temperature of the drill bit and the workpiece will rise, which will cause thermal deformation and dimensional error, affecting the machining accuracy. Therefore, a hole punching machine for bearing seat machining is proposed. Summary of the invention

[0004] The present invention aims to solve the technical problem that in the prior art, a large amount of heat is generated during the processing due to the high-speed friction and cutting action between the drill bit and the workpiece.

When the moving plate 302 moves downward and drives the two second screw rods 405 to move downward, the two second screw rods 405 move downward and drive the first bevel gear 503 to rotate forward and the two telescopic rods 406 to move downward in turn; When the two second screw rods 405 move downward and drive the first bevel gear 503 to rotate forward, the first bevel gear 503 rotates forward and drives the second bevel gear 506 to rotate forward, the second bevel gear 506 rotates forward and drives the rotating rod 505 to rotate forward, the rotating rod 505 rotates forward and drives the cooling fan 507 to rotate forward, the cooling fan 507 rotates forward so that the outside air passes through the cooling box 504, the cooling pipe 508, and the cooling bin 509 in sequence, and finally sprays to the drill bit 307 from the plurality of cooling heads 510, so as to cool the drill bit 307.

If the heat is not dissipated in time, the temperature of the drill bit 307 and the workpiece will increase, thereby causing thermal deformation and dimensional errors, affecting the machining accuracy.

Then, the staff turns on the two second cylinders 309 through the controller 6.

Then the staff turns on the first cylinder 301 through the controller 6, the first cylinder 301 extends to drive the movable plate 302 to move downward, the movable plate 302 moves downward to drive the first motor 303 to move downward, the first motor 303 moves downward to drive the first screw 304 to move downward, the first screw 304 moves downward to drive the slider 305 to move downward, the slider 305 moves downward to drive the second motor 306 to move downward, the second motor 306 moves downward to drive the drill bit 307 to move downward until the drill bit 307 contacts the surface of the bearing seat, at this time, the staff turns on the second motor 306 through the controller 6, the second motor 306 rotates to drive the drill bit 307 to rotate, thereby performing a hole drilling operation on the bearing seat; When the drilling operation is completed, the staff turns off the second motor 306 through the controller 6 and turns on the two second cylinders 309 at the same time. The two second cylinders 309 contract and drive the two clamping plates 310 to move away from each other, so that the two clamping plates 310 can be moved away from each other, which is convenient for the subsequent unloading operation of the bearing seat. Then the staff turns on the first cylinder 301 through the controller 6, and the first cylinder 301 contracts upward to drive the moving plate 302 to move upward, and the moving plate 302 moves upward to drive the first motor 303 and the two second screws 405 to move upward in turn; When the moving plate 302 moves upward and drives the first motor 303 to move upward, the first motor 303 moves upward and drives the first screw 304 to move upward, the first screw 304 moves upward and drives the slider 305 to move upward, the slider 305 moves upward and drives the second motor 306 to move upward, the second motor 306 moves upward and drives the cooling chamber 509 and the drill bit 307 to move upward in sequence; When the second motor 306 moves upward, it drives the drill bit 307 to move upward until the drill bit 307 is away from the bearing seat, which is convenient for subsequent material cutting operations; When the second motor 306 moves upward and drives the cooling chamber 509 to move upward, the cooling chamber 509 moves upward and drives the cooling heads 510 to move upward, so as to ensure that the cooling heads 510 are always aligned with the drill bit 307; When the moving plate 302 moves upward and drives the two second screw rods 405 to move upward, the two second screw rods 405 move upward and drive the first bevel gear 503 to rotate in the opposite direction and the two telescopic rods 406 to move upward in turn; When the two second screw rods 405 move upward and drive the first bevel gear 503 to rotate in the opposite direction, the first bevel gear 503 rotates in the opposite direction and drives the second bevel gear 506 to rotate in the opposite direction, and the second bevel gear 506 rotates in the opposite direction and drives the rotating rod 505 to rotate in the opposite direction, and the rotating rod 505 rotates in the opposite direction and drives the cooling fan 507 to rotate in the opposite direction, and the cooling fan 507 rotates in the opposite direction so that the waste gas generated during the hole opening operation in the hole opening box 7 passes through a plurality of cooling heads 510, cooling bins 509, cooling pipes 508, and cooling boxes 504 in sequence, and finally returns to the outside through the vent. If these waste gases are retained in the hole opening box 7, they will pollute the working environment and affect the health of the operators; When the two second screw rods 405 move upward and drive the two telescopic rods 406 to move upward, the two telescopic rods 406 move upward and drive the two slides 401 away from the discharge port respectively.

At this time, the bearing seat above the discharge port falls into the discharge box 407 under the action of gravity, thereby automatically completing the discharge work and avoiding the tedious operation and heavy physical labor during manual discharge. This not only reduces the labor burden of workers, but also reduces the risk of physical injury caused by long-term repetitive labor.
