Straight teeth and helical cylindrical gears can be cut on the hobbing machine, and worm wheels, sprocket wheels, etc. can also be processed. For example, a hobbing machine disclosed in publication number CN110170707A. Currently, most hobbing machines are basically numerically controlled.

[0003] During the processing of the current hobbing machine, the workpiece needs to be moved to a specified position for processing through a pallet, such as the X-axis pallet in the above patent. However, in the prior art and the above patent, there is no improvement on how to automatically lubricate the pallet during operation. The existing operation method is to directly add lubricant manually, which is rather inconvenient. Therefore, there are great limitations in actual use and there is room for improvement. Content of the Utility Model

[0004] The purpose of the utility model is to provide a feed inlet pallet structure of a hobbing machine to solve the problem that the pallet cannot be automatically lubricated proposed in the above background technique.

The oil outlet part partially penetrates the plate body and is in rolling connection with the slide rail; the oil storage part is arranged on the top of the oil outlet part, and the lubricating oil stored in the oil storage part is discharged by gravity and received by the oil outlet part, and then the lubrication between the plate body and the slide rail is realized through the oil outlet part, achieving the purpose of automatic lubrication.

[0006] Preferably, symmetric side grooves are opened on both sides of the top of the plate body, and a plurality of through holes are opened through the bottom of the side grooves. The oil outlet part includes a ball rotatably arranged in the side grooves and partially protruding outside the bottom of the plate body. The ball is in rolling fit with the slide rail. When the ball rotates, a small amount of lubricating oil adhered to the surface will lubricate the slide rail. At the same time, the lubricating oil consumed by this kind of lubrication is less, which can achieve long-term lubrication. At the same time, the rolling connection can reduce the friction between the plate body and the slide rail during movement.

[0007] Preferably, a filter screen is further installed inside the side groove. The filter screen is placed directly above the ball and is in rolling fit with the ball, so as to limit the ball and at the same time transmit the lubricating oil to the ball. The filter screen can be fixed by bolts or spot welding; the oil storage part is arranged on the filter screen.

[0008] Preferably, the oil storage part is a sponge pad, and the top surface of the sponge pad is lower than or flush with the horizontal plane of the opening of the side groove, so as to avoid protrusion and cause the phenomenon of lubricating oil overflow.

[0009] Preferably, the two side regions at the bottom of the plate body are in sliding fit with the top surface of the slide rail, and the vertical projection of the side groove is located at the two side regions at the bottom of the plate body, so as to ensure the lubrication of the slide rail.

[0010] Preferably, scrapers are installed at both ends of the plate body, only one end is shown in the figure, the scraper is directly above the slide rail, and the bottom end of the scraper is in contact with the surface of the slide rail, so as to scrape off the dust and other chips on the surface of the slide rail.

[0011] Preferably, long strip holes are formed on the surface of the scraper, and bolts screwed into the plate body penetrate through the long strip holes, so as to realize the installation of the scraper; an installation sleeve is also welded at one end of the plate body.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, through the self-lubricating component involved, automatic lubrication can be realized during the movement of the pallet, and the uniformity and comprehensiveness of lubrication can be ensured. There is no need for manual operation, and only the lubricating oil needs to be added regularly, which is very convenient to operate and perfects the deficiencies existing in the use of the existing structure.
