Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of transportation equipment, specifically relates to a centerless grinding machine feeding device. BACKGROUND

[0002] The centerless grinding machine is a kind of equipment widely used in the field of machining, and is used for the high-precision and high-efficiency grinding of the outer circle of rotary workpieces such as cylindrical and conical bodies.In the automatic production process of the centerless grinding machine, the automatic feeding of the workpiece is a crucial link.At present, the common automatic feeding mode is to use a vibrating disc feeding device, which makes the disc produce high-frequency micro-vibration through electromagnetic vibration, and uses the vibration effect to arrange the workpieces in disorder in the disc along a preset spiral track in order, and finally the workpieces are conveyed to the grinding mechanism through the track outlet.However, for small cylindrical workpieces with smooth surface and light weight, the feeding flow rate of the vibrating disc feeding device is unstable, and it is difficult to realize stable and uniform single conveying.Meanwhile, this unstable feeding mode can cause the feeding inlet of the grinding mechanism to be blocked by a large number of workpieces, which not only seriously interferes with the stable and continuous processing rhythm of the centerless grinding machine, but also causes shutdown due to the mutual collision and jamming of the workpieces at the feeding inlet, and manual intervention is required for cleaning, thereby reducing the automation degree and production efficiency of the whole machine.

[0003] Chinese patent CN105523366A discloses a spherical roller automatic feeding device, which comprises a vibrating disc mechanism and a conveying mechanism, and further comprises a distributing mechanism and a pushing mechanism; in the distributing mechanism, an industrial camera is used to detect and identify the end face direction of the spherical roller, a stepping motor drives a distributing fan blade to distribute the spherical rollers with different directions into different slides, a distributing spiral slide and a distributing straight slide are used to convey the spherical rollers to corresponding channels of a belt conveyor, and the belt conveyor is divided into two conveying channels by a baffle corresponding to two roller grinding machines; in the pushing mechanism, a telescopic mechanism is installed in front of the feeding inlet of the grinding machine, and is used to push the spherical rollers into the feeding inlet of the grinding machine.The patent can automatically identify the end face of the roller and sequentially convey the roller to the roller grinding machine, and can meet the processing of spherical rollers of different specifications, but the core feeding component of the patent is still a vibrating disc, and for small cylindrical workpieces with smooth surface, the inherent pulse feeding characteristics of the vibrating disc can cause unstable flow of the workpieces and easy piling out, thereby making it difficult to realize stable and continuous single conveying, and there is a high risk of jamming.

[0022] The present invention will now be described and illustrated in detail with reference to the embodiments.

[0023] Example 1

[0024] like Figs. 1-3 As shown, the centerless grinding machine feeding device includes a rotary feeding mechanism disposed on one side of the centerless cylindrical grinding machine 1. The rotary feeding mechanism includes a rotatable feeding bin 2, which is generally arranged in the shape of an inverted hollow frustum. Several sets of columnar workpieces are disposed inside the feeding bin 2. A spirally extending edge track 3 is fixedly disposed on the inner side wall of the feeding bin 2. The edge track 3 is arranged around the central axis of the feeding bin 2 and forms a spiral upward channel from the bottom to the top of the feeding bin 2. A guide baffle 4 is disposed on the feeding bin 2 in conjunction with the edge track 3. A conveying track 5 is disposed on the centerless cylindrical grinding machine 1 in conjunction with the edge track 3. A connecting guide plate 6 is disposed on the conveying track 5 in conjunction with the edge track 3.

[0025] One end of the connecting guide plate 6 is fixedly connected to the conveying track 5, and the other end of the connecting guide plate 6 is slidably connected to the edge track 3.

[0026] A vertical central rotating shaft is fixedly installed on the feeding bin 2, and the central rotating shaft is located on the central axis of the feeding bin 2.

[0027] A speed-regulating motor is installed at the bottom of the feeding bin 2, and the speed-regulating motor is connected to the central rotating shaft of the feeding bin 2 through gear transmission.

[0028] The bottom of the conveying track 5 is provided with several sets of support frames 7, and the conveying track 5 is installed on the centerless cylindrical grinding machine 1 through several sets of support frames 7.

[0029] The top of the conveying track 5 is provided with a conveying pipe 8, which is in the form of a hollow circular pipe as a whole.

[0030] The cylindrical workpiece is in the form of a cylinder as a whole.

[0031] The width of the cross section of the edge track 3 is greater than the diameter of the cylindrical workpiece, and the width of the cross section of the edge track 3 is less than the length of the cylindrical workpiece.

[0032] The edge track 3 is provided with a limiting baffle 9 away from the feeding bin 2.

[0033] The limiting baffle 9 is in sliding connection with the edge track 3.

[0034] Working principle and process:

[0035] When working, the cylindrical workpieces to be processed are placed in the feeding bin 2 in batches. Start the device, and the speed regulating motor at the bottom of the feeding bin 2 drives the center shaft through the gear, and drives the entire feeding bin 2 to rotate uniformly around the center axis. Under the action of the rotation of the feeding bin 2, the cylindrical workpieces in the feeding bin 2 enter the edge track 3 fixed to the inner wall of the feeding bin 2. Since the width of the cross section of the edge track 3 is greater than the diameter of the cylindrical workpiece and the width of the cross section of the edge track 3 is less than the length of the cylindrical workpiece, the cylindrical workpiece is automatically constrained to be in a posture with the length direction parallel to the extension direction of the edge track 3, and automatic directional arrangement is realized.

At the end of the edge track 3, the cylindrical workpiece first passes through the guide baffle 4, and the cylindrical workpiece that successfully passes through the guide baffle 4 realizes smooth transition from the rotating feeding bin 2 to the fixed conveying track 5 through the connecting guide plate 6, greatly reducing the risk of jamming; the cylindrical workpiece that does not successfully pass through the guide baffle 4 is blocked by the guide baffle 4 and falls back into the feeding bin 2.

[0037] Finally, the cylindrical workpiece is continuously and stably conveyed to the grinding mechanism of the centerless cylindrical grinding machine 1 through the conveying pipe 8, meeting the feeding demand of the centerless cylindrical grinding machine 1 for efficient and automated production.
