Abstract

The present invention relates to a feed tray which comprises an outer casing body and a circular tray-shaped inner core, wherein the outer casing body is coaxially arranged, is mutually and integrally fixed and is a hollow tray body formed by splicing two semi-circular ring casing bodies; the periphery of the outer casing is distributed with a plurality of U-shaped grooves; the circumference of the inner core is exposed on the root parts of the U-shaped grooves on the periphery of the outer casing. The present invention is provided with positioning base points on the circumference of the inner core and the two inner side walls of each of the U-shaped grooves, and thus, the U-shaped grooves with the required precision can be processed only by the ordinary cutting machine, and the concentricity of the circumference of the inner core can be ensured only by the need of the ordinary processing. Therefore, on the premise that the processing quality is ensured, the processing cost of the feed tray is greatly reduced, and the processing is easy and rapid. In addition, when the positioning points on the circumference of the inner core are worn, screws can be detached, the inner core is rotated at an angle relatively to the outer casing, and the circumference of the inner core, which is not worn, is exposed on the roots of the U-shaped grooves of the outer casing. Thus, the service life of the feed tray can be extended, and the production cost is further reduced.

Description

Feed table

Technical field

The present invention relates to a kind of feed table that in industrial manufacturing process, is used for carrying cylindric material.

Background technology

Cylindric material is carried out in the bulb ground finish of end, need come convey materials with the disc feed table, generally the periphery at feed table is equipped with a plurality of grooves, the bottom of each groove has the chamfered groove that is 90 ° of angles again, as shown in Figure 7 and Figure 8, adding man-hour, with the incircle of groove and the point of contact b of its bottom two square edges, c is as the location benchmark, so, in order to guarantee crudy, must be within 0.008mm with the incenter of each groove and the distance of center circle error control between the feed table center, in order to reach so high accuracy of manufacture, existing feed table adopts the import free of losses usually, the wire cutting machine of being careful carries out retrofit, and could reach above-mentioned requirements reluctantly after 35 hours～40 hours consuming time, obviously, though such processing result has guaranteed the precision of each groove, but it is very expensive that the manufacturing cost that makes feed table simultaneously becomes, so that affected indirectly tooling cost, limited the further development of bulb mill special machine.In addition, in the course of processing, because each groove datum is easier to be worn, in case and this phenomenon appears in one of them recess-based on schedule, then hesitate to discard, and the condemnation factor of using that can increase bulb so the feed table of said structure is shorter service life, thereby has further influenced tooling cost.

Summary of the invention

Technical matters to be solved by this invention is the present situation at prior art, and the feed table of a kind of easy to process, low cost of manufacture and long service life is provided.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: this feed table comprises coaxial setting and interfixes unitary housing and the discoid inner core that is positioned at it, described shell is the hollow disk body that is put together by two semicircular ring housings, described shell circumferential distribution has a plurality of U type grooves, described inner core periphery is exposed to the U type root of notch on the described shell periphery, and the madial wall of the U type groove on described inner core periphery and the described shell periphery should guarantee corresponding right alignment.

Described U type groove is to be distributed on the described shell periphery to good.

Described inner core and described shell can adopt screw to run through fastening forming behind both end face.It is coaxial fixing also can to adopt welding or other fixed form to carry out.

Spacer portion between the adjacent grooves of described shell is good with solid, locatees mutually with the periphery of inner core with convenient, makes shell and inner core coaxial.

Also can be distributed with a plurality of lightening holes on the described inner core, so that loading and unloading.

Compared with prior art, on the periphery and the madial wall of U type groove of the present invention by setting base being arranged on inner core, periphery with inner core is orientated the master as, make the distance of center circle error between interior incenter of U type groove and the feed table center be controlled within the 0.008mm easily, because the concentricity of inner core periphery is easily guaranteed by common job operation, the required also available ordinary lines cutting machine of precision of the U type groove of shell processes, therefore, under the prerequisite that guarantees crudy, reduced the tooling cost of feed table widely, and easy to process, quick; In addition, when the locating point of inner core periphery is worn, can unload screw, inner core is rotated an angle with respect to shell, make the inner core periphery that was not worn expose shell U type root of notch and again fix screw get final product, so just can prolong the service life of feed table, further reduce productive costs.

The specific embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

Extremely shown in Figure 6 as Fig. 1, this feed table comprises the shell 1 of coaxial setting and is positioned at its discoid inner core 2, described shell 1 is the hollow disk body that is put together by two hemi-

toroidal shell body

1a, 1b, be distributed with the identical U type groove 11 of a plurality of shapes equably at shell 1 periphery, described inner core 2 peripheries are exposed to U type groove 11 roots on shell 1 periphery, and it is after running through both end face mounting holes 12 respectively by six screws 3 between inner core 2 and the shell 1, coaxial fastening and be integral.The madial wall that should guarantee the U type groove 11 on inner core 2 peripheries and shell 1 periphery simultaneously has corresponding right alignment.

When making two hemi-

toroidal shell body

1a, 1b, with single-piece shell of turning processing, on circumference, process required U type groove 11 with common line cutting more earlier, by shown in Figure 6, sever into two then; And processing is during inner core 2, and behind surface hardening, correct grinding axis hole 21 is joined axle with axis hole 21 location to its periphery more earlier, and mill inner core periphery and end face can reach required precision.

During assembling, two hemi-

toroidal shell body

1a, 1b tightly are enclosed within on described inner core 2 peripheries, use six screws 3 that the two is fastening again, at this moment, cylindric material is carried out bulb, and to add the setting base in man-hour be the C1 point place (as shown in Figure 4) of the madial wall of inner core periphery B1 point place and U type groove, as long as guarantee the right alignment of the two, can satisfy the inscribed circle O1 of each groove 11 and the distance of center circle R between the inner core center O and guarantee within desired error limit.

In order to alleviate the weight of inner core 2, in the present embodiment, on described inner core 2, also be evenly equipped with a plurality of lightening holes 22 with one heart, so that loading and unloading.Simultaneously, the spacer portion 13 between the adjacent grooves 11 of described shell is a solid, locatees mutually with the periphery of inner core 2 with convenient, makes shell and inner core 2 coaxial.
