Description

Technical Field

[0001] The utility model relates to the technical field of feeders, in particular to an automatic feeder for a centerless grinder. Background Art

[0002] The automatic feeder for centerless grinder is an automatic feeding device designed for centerless grinder. It can realize automatic loading, feeding and discharging of workpieces, greatly improving production efficiency and processing accuracy. This equipment is an indispensable part of modern manufacturing, especially in areas that require high-precision and high-efficiency processing, such as automotive parts, precision machinery parts, etc. It automatically feeds raw materials into the grinder for processing, thereby improving production efficiency and reducing labor costs. It can also automatically complete the clamping and feeding of workpieces, reducing the time of manual operation, and can also accurately control the positioning of workpieces. Positioning and feeding avoids the errors that may be caused by manual operation, ensures processing quality, reduces the labor intensity of workers, reduces the difficulty of workers' operation, and improves production safety. The traditional automatic feeder for centerless grinders used for shaft sleeve processing adopts a wheeled conveying channel to roll the ring workpiece on the conveying channel to the feeding place of the centerless grinder by its own weight. During the rolling process, the shaft sleeve workpiece is prone to side rotation or sideways, which makes it impossible for the centerless grinder to keep the axis of the workpiece parallel to the axis of the grinding wheel when feeding, affecting the processing effect. For this reason, we propose an automatic feeder for centerless grinders. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic feeder for a centerless grinder, comprising a base, a machine box fixedly installed at the rear of the base, a feed box fixedly installed at the rear of the base, a guide shaft provided under the feed box, a conveying shaft fixedly connected to the end of the guide shaft, the conveying shaft being connected to the centerless grinder, and a feeding device also provided on the base.

[0005] There is a circular groove at the bottom of the feed box, the diameter of the circular groove is slightly larger than the diameter of the workpiece, and the inner wall of the feed box is four inclined surfaces facing the circular groove.

[0006] The diameter of the conveying shaft is equal to the diameter of the workpiece.

[0007] Among them, the feeding device includes a fixed block, a sliding groove is opened on the fixed block, a slider is slidably installed in the sliding groove, a first limiting block is fixedly installed on the outer end of the fixed block, a second limiting block is fixedly installed on the inner end of the fixed block, a sliding shaft is fixedly installed between the first limiting block and the second limiting block, the slider can slide freely on the sliding shaft, a push block is fixedly installed on the inner end of the slider, the upper part of the slider is rotatably connected to a connecting rod, the other end of the connecting rod is rotatably connected to a rotating arm, a turbine is rotatably installed on the chassis, the rotating arm is fixedly connected to the turbine, a worm is rotatably installed in the chassis, a motor is fixedly installed at the bottom of the chassis, and the motor and the worm are connected by a belt.

[0008] The first limiting block is provided with a first circular hole, and the diameter of the circular hole is the same as that of the sliding shaft.

[0009] The push block is in the shape of a combination of a disc and a cylinder, and a groove is provided on the upper part of the push block, through which the guide shaft can pass.

[0010] The second limiting block is provided with a second circular hole, and the diameter of the second circular hole is the same as the diameter of the cylinder on the pushing block.

[0011] The utility model has at least the following beneficial effects:

[0012] The utility model prevents the shaft sleeve workpiece from rotating or falling sideways during transportation through the feeding device, so that the axis of the workpiece and the axis of the grinding wheel can be kept parallel when the centerless grinder is feeding, and at the same time the feeding efficiency and stability are improved, and the time of manual adjustment is saved.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0024] Example 1

[0025] See also Figures 1 to 8 The utility model provides a technical solution: an automatic feeder for a centerless grinder, comprising a base 1, a chassis 2 fixedly mounted at the rear of the base 1, a feed box 3 also fixedly mounted at the rear of the base 1, a circular groove 30 being opened at the bottom of the feed box 3, the diameter of the circular groove 30 being slightly larger than the diameter of the workpiece, the inner wall of the feed box 3 being four inclined surfaces facing the circular groove 30, a guide shaft 4 being provided below the feed box 3, a conveying shaft 5 being fixedly connected at the end of the guide shaft 4, the diameter of the conveying shaft 5 being equal to the diameter of the workpiece, the conveying shaft 5 being connected to the centerless grinder, and a feeding device 6 being also provided on the base 1.

[0026] The feeding device 6 includes a fixed block 60, a slide groove 61 is opened on the fixed block 60, a slider 62 is slidably installed in the slide groove 61, a first limiting block 63 is fixedly installed on the outer end of the fixed block 60, a first circular hole 630 is opened on the first limiting block 63, a second limiting block 64 is fixedly installed on the inner end of the fixed block 60, a second circular hole 640 is opened on the second limiting block 64, a sliding shaft 65 is fixedly installed between the first limiting block 63 and the second limiting block 64, the diameter of the sliding shaft 65 is equal to the circular hole, the slider 62 can slide freely on the sliding shaft 65, and the slider 62 is fixed on the inner end. A push block 66 is fixedly installed, and the push block 66 is a combination of a disc and a cylinder. The diameter of the cylinder is the same as the diameter of the second circular hole 640. A groove 660 is opened on the upper part of the push block 66, and the groove 660 can be passed by the guide shaft 4. The upper part of the slider 62 is rotatably connected to a connecting rod 67, and the other end of the connecting rod 67 is rotatably connected to a rotating arm 68. A turbine 69 is rotatably installed on the chassis 2, and the rotating arm 68 is fixedly connected to the turbine 69. A worm 610 is rotatably installed in the chassis 2, and a motor 611 is fixedly installed at the bottom of the chassis 2. The motor 611 and the worm 610 are connected by a belt 612.

[0027] When the feeder is working, the workpiece can be poured into the material box 3, and the workpiece will slide from the circular groove 30 to the guide shaft 4.
