Description

Technical Field

[0001] The utility model belongs to the technical field of roller processing, and in particular relates to a roller pump. Background Art

[0002] The roller is the element that bears the load when the bearing is running. It is the weakest part in the roller bearing. Its manufacturing quality has a great influence on the working performance of the bearing (such as rotation accuracy, vibration, noise and flexibility, etc.) and is the main factor affecting the service life of the bearing.

[0003] During the production of tapered rollers, the scattered products from the previous process need to be sorted and arranged in an orderly manner before entering the processing machine. Due to the heavy weight of the rollers, the rollers are generally sorted by a low-level sorting machine through rolling rods, but the discharge height of the sorting machine is much lower than the height of the machine, so a device is needed to lift the rollers from the sorting machine to the machine entrance in an orderly manner.

[0004] In the existing technology, there are two ways to connect the material handling machine and the machine tool:

[0005] (1) Raise the low-level material sorting machine frame and align the outlet height with the machine tool inlet. This method is inconvenient when the hopper needs to add rollers. Manually, it is impossible to see the number of rollers in the material sorting machine hopper and add them in time.

[0006] (2) The existing roller pump is used to connect the material handling machine and the machine tool. However, the existing roller pump usually uses a metal pressure wheel, which will damage the roller surface, so it can only be used in the blank process. Utility Model Content

[0049] Reference Figures 1 to 4 The embodiment of the utility model provides a roller pump, which includes a mounting base plate 1, a driving mechanism 2, a frame 3, a material unloading tooling pipe 4, an upper pressing wheel 51, a lower pressing wheel 61, an upper connecting shaft 52 and a lower connecting shaft 62.

[0050] The driving mechanism 2 is arranged on the mounting base plate 1 .

[0051] The frame 3 is arranged on the mounting base plate 1 .

[0052] The unloading tool pipe 4 is a tubular structure with openings at both ends. The unloading tool pipe 4 is arranged on the frame 3. The middle upper and lower sides of the unloading tool pipe 4 have avoidance openings 41 that connect the inside and the outside. One end of the unloading tool pipe 4 is opened to connect the discharge pipe of the material handling machine, and the other end of the unloading tool pipe 4 is opened to connect the discharge pipe to the feed port of the machine tool. The inside of the unloading tool pipe 4 is for the roller 9 to pass through. Preferably, the unloading tool pipe 4 is made of polyurethane material.

[0053] The upper pressing wheel 51 and the lower pressing wheel 61 are relatively located at the upper and lower sides of the middle of the blanking tool pipe 4. The upper pressing wheel 51 extends into the blanking tool pipe 4 through the upper avoidance opening 41, and the lower pressing wheel 61 extends into the blanking tool pipe 4 through the lower avoidance opening 41. The upper pressing wheel 51 and the lower pressing wheel 61 are made of polyurethane material. The flexible polyurethane material will not scratch the roller 9. Compared with the old roller pump, the problem of the pressing wheel damaging the product is solved.

[0054] The upper connecting shaft 52 is connected to the upper pressing wheel 51 and is arranged on the frame 3 through an upper bearing.
