Description

Technical Field

[0001] The utility model relates to the production technical field of roller processing equipment, and more specifically, the utility model relates to an automatic loading and conveying line for a centerless grinding machine of bearing rollers. Background Art

[0002] During the roller processing, a centerless grinding machine is needed to process the roller raceway surface. When grinding with a centerless grinding machine, the rollers need to move forward tightly in sequence in a spiral manner. When there are gaps between the rollers, the grinding quality will be unqualified.

[0003] Currently, it is generally conveyed through a V-shaped chain plate line, and manual intervention is used to align and assist in pushing the rollers into the grinding machine. Manual operation will increase the labor intensity of employees and cause product unqualified phenomena due to human factors, affecting the processing quality of the rollers. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an automatic loading and conveying line for a centerless grinding machine of bearing rollers.

[0005] To achieve the above object, the utility model provides an automatic loading and conveying line for a centerless grinding machine of bearing rollers, and its structure includes a frame. The innovation lies in that: from left to right, the frame is successively provided with a first V-shaped conveyor belt and a second V-shaped conveyor belt. The first V-shaped conveyor belt and the second V-shaped conveyor belt are arranged in left-right alignment. The transmission speed of the first V-shaped conveyor belt is greater than that of the second V-shaped conveyor belt. A material guiding plate is arranged between the first V-shaped conveyor belt and the second V-shaped conveyor belt.

[0006] Further, a first passive roller path is provided at the transmission starting end of the first V-shaped conveyor belt, a first active roller path is provided at the transmission ending end of the first V-shaped conveyor belt, a second active roller path is provided at the transmission starting end of the second V-shaped conveyor belt, and a second passive roller path is provided at the transmission ending end of the second V-shaped conveyor belt.

[0013] Figure 2 Enlarged view of part A of the present utility model. Detailed Embodiment

[0014] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0015] As From Figure 1 to Figure 2 A specific embodiment of the present utility model has a structure including a frame 12. The frame 12 is sequentially provided with a first V-shaped conveyor belt 1 and a second V-shaped conveyor belt 11 from left to right. The first V-shaped conveyor belt 1 and the second V-shaped conveyor belt 11 are arranged in left-right alignment. The transmission speed of the first V-shaped conveyor belt 1 is greater than that of the second V-shaped conveyor belt 11. A material guiding plate 2 is provided between the first V-shaped conveyor belt 1 and the second V-shaped conveyor belt 11.

[0016] The present utility model is applied to the feeding of rollers on a centerless grinder, and the process is as follows: The rollers to be processed are fed from the first V-shaped conveyor belt 1. Under the transmission of the first V-shaped conveyor belt 1, the rollers are transmitted to the transmission end of the first V-shaped conveyor belt 1. Since the first V-shaped conveyor belt 1 is inclined downward, under the action of its own gravity, the rollers enter the second V-shaped conveyor belt 11 through the material guiding plate 2. The second V-shaped conveyor belt 11 conveys the rollers to the centerless grinder for feeding. During the entire feeding process, since the transmission speed of the first V-shaped conveyor belt 1 is greater than that of the second V-shaped conveyor belt 11, this speed difference can ensure that the rollers can closely follow one by one when entering the second V-shaped conveyor belt 11 and then enter the centerless grinder, thus ensuring the processing quality of the rollers.

[0017] In the present utility model, as a preferred solution, a first passive roller path 3 is provided at the transmission starting end of the first V-shaped conveyor belt 1, a first active roller path 31 is provided at the transmission ending end of the first V-shaped conveyor belt 1, a second active roller path 32 is provided at the transmission starting end of the second V-shaped conveyor belt 11, a second passive roller path 33 is provided at the transmission ending end of the second V-shaped conveyor belt 11, and the first active roller path 31 and the second active roller path 32 are arranged in parallel with each other;

[0018] One end of the first active roller path 31 is provided with a rotating motor 4, the other end of the first active roller path 31 is provided with a driving wheel 41, the end of the second active roller path 32 is provided with a driven wheel 42, the diameter of the driving wheel 41 is smaller than that of the driven wheel 42, and a belt 43 is connected between the driving wheel 41 and the driven wheel 42.

[0019] In the present utility model, the transmissions of the first V-shaped conveyor belt 1 and the second V-shaped conveyor belt 11 are both powered by the rotating motor 4. When the rotating motor 4 is turned on, it drives the first active roller path 31 to rotate, and the first passive roller path 3 rotates, thereby driving the first V-shaped conveyor belt 1 to rotate. At the same time, through the action of the belt 43, the rotation of the driving wheel 41 drives the driven wheel 42 to rotate synchronously, thereby driving the second active roller path 32 to rotate, and the second passive roller path 33 rotates synchronously, realizing the rotation of the second V-shaped conveyor belt 11. Since the diameter of the driving wheel 41 is smaller than that of the driven wheel 42, the rotation speed of the driving wheel 41 is greater than that of the driven wheel 42, and thus the transmission speed of the first V-shaped conveyor belt 1 is greater than that of the second V-shaped conveyor belt 11.

[0020] In the present utility model, as a preferred solution, a fixing plate 5 is provided on the side surface of the above-mentioned frame 12. The fixing plate 5 is located between the driven wheel 42 and the driving wheel 41, and a rotatable pressing wheel 51 is provided on the top of the fixing plate 5, and the pressing wheel 51 is attached to the belt 43.

[0021] In the present utility model, the pressing wheel 51 is attached to the belt 43, which can tighten the belt 43, thereby ensuring the stability of the connection between the driving wheel 41 and the driven wheel 42.

[0022] In the present utility model, as a preferred solution, a V-shaped guiding surface 21 is formed at the central position of the above-mentioned guiding plate 2, and the two ends of the V-shaped guiding surface 21 are respectively aligned with the first V-shaped conveyor belt 1 and the second V-shaped conveyor belt 11.

[0023] In the present utility model, as a preferred solution, a V-shaped opening 22 is provided at the bottom of the front section of the V-shaped guiding surface 21. The V-shaped opening 22 is attached above the transmission ending end of the first V-shaped conveyor belt 1, and a strip-shaped groove 23 is provided at the bottom of the rear end of the V-shaped opening. The strip-shaped groove 23 extends and is attached above the transmission starting end of the second V-shaped conveyor belt 11.

[0024] In the present utility model, when the roller reaches the transmission end of the first V-shaped transmission belt 1, it can quickly roll into the interior of the V-shaped guiding surface 21 through the V-shaped opening 22, and then enter the transmission start end of the second V-shaped transmission belt 11 along the extension direction of the strip-shaped groove 23.
