Description

Technical Field

[0001] The utility model relates to the technical field of centerless grinder piston rod processing, in particular to a centerless grinder piston rod transmission mechanism. Background Art

[0002] When machining piston rods on a centerless grinder, they are first fed to the grinding area via a loading mechanism. After grinding, they are then transported by a conveyor mechanism to the unloading mechanism for unloading. Because some of the polished piston rods may not meet the required polishing finish and require a second round of grinding, the conventional conveyor mechanism sends all polished piston rods to the unloading mechanism, making it impossible to distinguish those requiring a second round of grinding. This results in poor quality control of the finished piston rods. Alternatively, the unloading mechanism screens the piston rods requiring a second round of grinding, which can be very hot after grinding, and this manual screening process can result in burns.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figure 1-5 The piston rod transmission mechanism of a centerless grinder shown in FIG. includes a transmission trough 1, which is fixedly connected to a support body 2 via support columns 22. A conveyor belt 3 is connected to the transmission trough 1. The piston rod is limited by the transmission trough 1 and transmitted via the conveyor belt 3. A first L-shaped mounting plate 4 is fixedly connected to the transmission trough 1. An infrared detection device 5 is fixedly connected to the horizontal plate of the first L-shaped mounting plate 4. The infrared detection device 5 is connected to a display screen and uploads a detection image to the display screen. The display screen is then manually observed to determine whether the piston rod has been polished to a qualified standard. A window 6 is provided on the conveying trough 1, and a baffle 7 is slidably connected to the window 6. The baffle 7 is fixedly connected in the mounting groove 8, and the mounting groove 8 is fixedly connected to the first electric telescopic rod 9 or the limit rod 10. The limit rod 10 is slidably connected in the limit groove 11. The first electric telescopic rod 9 and the limit groove 11 are fixedly connected to the supporting body 2. The above structure enables the baffle 7 to move stably in the vertical direction; a second L-shaped mounting plate 12 is fixedly connected to the supporting body 2 through a support column 22, a second electric telescopic rod 13 is fixedly connected to the second L-shaped mounting plate 12, and a push plate 14 is fixedly connected to the second electric telescopic rod 13; a rod collecting groove 15 is also fixedly connected to the supporting body 2, and one end of the rod collecting groove 15 is slidably connected to the baffle 7.

[0018] The two ends of the conveying trough 1 are rotatably connected with a rotating shaft, one of which is sleeved with a transmission roller, and the other is sleeved with a driving roller 16, and the transmission roller and the driving roller 16 are sleeved with a conveyor belt 3, and one end of the rotating shaft sleeved with the driving roller 16 is fixedly connected to the output shaft of the servo motor 17, and the servo motor 17 is fixedly connected to the motor mounting plate 18, and the motor mounting plate 18 is fixedly connected to the support body 2 through the support column 22.

[0019] The push plate 14 is L-shaped. A second electric telescopic rod 13 is fixedly connected to the vertical plate of the second L-shaped mounting plate 12.
