Description

Technical Field

[0001] The present invention relates to relevant technical fields, and in particular to a numerically controlled lathe for automatically machining cylindrical rollers for bearings. Background Art

[0002] Cylindrical roller is a type of bearing. Its internal structure adopts parallel arrangement of rollers. Spacers or isolation blocks are installed between the rollers to prevent the rollers from tilting or rubbing against each other, effectively preventing the increase of rotational torque. It is one of the most common bearings. During the processing of this type of bearing, it is usually necessary to use a lathe to grind the cylindrical rollers to ensure the overall smoothness of the cylindrical rollers.

[0003] In the current CNC machine tools, when automatically processing bearing cylindrical rollers, workers usually manually place the cylindrical rollers on a triangular chuck, clamp the cylindrical rollers with the triangular chuck, and then manually start the lathe grinding mechanism to complete the processing of the cylindrical rollers. After the processing is completed, the workers need to manually take out the cylindrical rollers and then put new cylindrical rollers back in. This loading and unloading method not only leads to low processing efficiency of the cylindrical rollers, but also requires workers to manually approach the lathe grinding components, which not only has a large safety hazard, but also the high temperature of the processed cylindrical rollers can easily burn the workers. In addition, the dust generated during the processing of the cylindrical rollers will float in the workshop and increase the dust content in the workshop environment, which will be inhaled into the body by the workers while they are working, thereby directly affecting the health of the workers. There is room for improvement. Summary of the Invention

The cleaning frame 711 is an upper opening structure, and a feeding hole is provided on the left side of the cleaning frame 711. The surface of the circular frame 706 is connected with a feeding pipe 712 and a discharging pipe 713. The feeding pipe 712 is away from one side of the circular frame 706.

After the triangular chuck 305 drives the cylindrical roller to move below the grinding disk 206, the grinding disk 206 moves down and contacts the surface of the cylindrical roller. At this time, the servo motor 702 is started, and the servo motor 702 drives the forward and reverse screw rods 703 to rotate, and drives the two moving blocks 704 to approach each other through the forward and reverse threads on the surface. The two moving blocks 704 can drive the two The rectangular clamping frames 705 are close to each other until the two rectangular clamping frames 705 contact each other. At this time, the two rectangular clamping frames 705 completely wrap the triangular chuck 305 and the grinding disc 206. After the grinding disc 206 is started to grind the cylindrical roller, the drive motor 707 is started synchronously. The drive motor 707 can drive the blade 709 to rotate through the circular shaft 708. The blade 709 generates centrifugal force in the circular frame 706, and the dust generated during the grinding process is transported to the cleaning frame 711 through the feed pipe 712 and the discharge pipe 713, so that the dust generated during the grinding process will not float in the workshop, thereby reducing the dust content in the workshop, having a better protection effect on the staff, and eliminating the need for manual cleaning by the staff.

[0024] Working principle: First, place the cylindrical roller of the bearing to be processed in the material frame body 501 on the left. When the cylindrical roller needs to be processed, the fourth motor 602 drives the feed plate 604 to rotate through the rotating shaft 603, so that the feed plate 604 drives the arc frame 612 to rotate to the inside of the left material frame body 501. At this time, the third motor 502 drives the pulley 504 to rotate through the transmission shaft 503, thereby driving the cylindrical roller on the feeding belt 505 to move to the right until the surface of the cylindrical roller contacts the rubber contact pad 613 on the inner wall of the arc frame 612. At this time, the vacuum pump 608 starts, and the air in the arc frame 612 is sucked through the suction pipe 609. The air is extracted, and the cylindrical roller is adsorbed on the inner wall of the arc frame 612 by negative pressure adsorption. After being fixed, the fourth motor 602 drives the feed plate 604 to rotate 180 degrees through the rotating shaft 603. At this time, the arc frame 612 can drive the cylindrical roller to rotate onto the triangular chuck 305. After the triangular chuck 305 is started, it can clamp the cylindrical roller from the inside, and the feed plate 604 returns to the position of the material frame body 501. At this time, the second motor 302 drives the movable frame 304 to move backward through the screw rod 303, thereby driving the triangular chuck 305 to move to the position below the grinding disc 206, and the first motor 202 drives the transmission frame 204 through the threaded rod 203 The movable frame 304 returns to its original position after the grinding is completed, and the feeding plate 604 on the right drives the arc frame 612 to rotate to the left until it contacts the surface of the cylindrical roller on the triangular chuck 305. At the same time, after the arc frame 612 adsorbs the surface of the cylindrical roller, the triangular chuck 305 is released, and the feeding plate 604 on the right turns 180 degrees and drives the processed cylindrical roller to move to the inside of the right material frame body 501, thereby eliminating the need for manual loading and unloading operations by staff, greatly improving the processing efficiency of the cylindrical roller and increasing safety. In addition, during the grinding process, the servo motor 702 starts to drive the forward and reverse screws 703 to rotate, and drives the two rectangular clamping frames 705 through the two moving blocks 704 to wrap the triangular chuck 305 and the grinding disk 206. At the same time, the driving motor 707 drives the blade 709 to rotate through the circular shaft 708, forming a centrifugal force in the circular frame 706, thereby forming an adsorption force in the right rectangular clamping frame 705 through the feed pipe 712, and transporting the debris and dust to the cleaning frame 711 through the discharge pipe 713, so that the dust generated during the grinding process will not float in the workshop, thereby reducing the dust content in the workshop and improving the protection effect on the staff.
