Abstract
The utility model provides a cushion cutting apparatus, which comprises a rail, a knife rest and a centering rod which are respectively threading the rail, a blade fixed under the knife rest through blade fastening screws, and two fastening screws for fixing the position of the rail and the centering rod, wherein a cup-shaped underpan is further arranged under the centering rod, a bearing is mounted in the cup-shaped underpan, and three thimbles are respectively arranged on the three directions of 0 DEG, 120 DEG, 240 DEG of the lower head face of the underpan. The cushion cutting apparatus of the utility model can fix the centering thimble tightly, thereby promoting the cutting efficiency and precision, and greatly promoting the cutting quality.
Description
Technical field
The utility model relates to a kind of pad apparatus of cutting, relate in particular to a kind of make that the centering thimble fixedly secures cut the pad apparatus.
Technical background
Pad belongs to consumable accessory in valve parts, in valve was repaired, pad was also taked spot repair and homemade method except the employing standby redundancy is directly changed.Can the making of pad and repairing quality " run, drip, leak " with the static seal point that is directly connected to valve.Therefore, to the making of pad, must strictly carry out the relevant technologies standard.Existing market has many pad devices of cutting, most of shape as shown in Figure 1, comprise a cross bar 2 ', pass a knife rest 5 ' and certain core bar 4 ' of this cross bar 2 ' respectively, one is fixed in blade 6 ' under the knife rest 8 ' and two holding screws 1 ' that are used for fixing cross bar 2 ' and centering bar 4 ' position by blade holding screw 7 ', centering thimble 3 ' is installed on the centering bar, during the cutting pad, need hardwood plate of pad on workbench, adjust blade 6 ' to the distance between the centering thimble 3 ' by the shim size requirement, fixedly thimble 3 ' is determined center of circle horizontal direction rotating horizontal pole 2 ' then, can finish cutting on request, but in the cutting process of routine, because pad is thicker, be generally 0.5 to 1.5mm, therefore need bigger power to rotate several circles and just can finish cutting, in the cutting process, because the tangential force that centering thimble 3 ' is justified, thereby eccentric easily, the pad that causes shearing is not the circle of a standard, does not reach required precision.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and a kind of pad apparatus of cutting is provided, and the utility model can make the centering thimble fixedly secure, and has improved cutting system efficiency and precision, has improved the quality of cutting greatly.
The technical scheme that realizes above-mentioned purpose is: a kind of pad apparatus of cutting, comprise a cross bar, pass a knife rest of this cross bar and certain core bar, one respectively and be fixed in blade knife rest under and two by the blade holding screw and be used for fixing cross bar and the holding screws of the bar position of feeling relieved, wherein, also be provided with the cup-shaped chassis of a buried bearing under the described centering bar, the lower surface on this chassis is respectively arranged with a thimble on 0 °, 120 °, 240 ° three directions.
The above-mentioned pad apparatus of cutting, wherein, described centering bar and brearing bore are interference fit.
The above-mentioned pad apparatus of cutting, wherein, described bearing top circle surface is an interference fit with the chassis endoporus.
The above-mentioned pad apparatus of cutting wherein, also comprises the bearing cap of a band centre bore, and it can pass on the end face of openend that the centering bar is installed in the chassis.
The beneficial effects of the utility model are: a kind of pad apparatus of cutting of the present utility model is provided with three thimbles, the tangential force that thimble is not justified, can not produce eccentric phenomena, and firmly less, control easily, the pad precision of cutting is higher, has improved the quality of cutting.
Description of drawings
Fig. 1 is a kind of structural representation of cutting the pad apparatus of prior art;
Fig. 2 is a kind of structural representation of cutting the pad apparatus of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 2, show a kind of pad apparatus of cutting of the present utility model, it comprises a cross bar 2, pass a knife rest 8 and certain core bar 3 of this cross bar 2 respectively, one is fixed in blade 9 under the knife rest 8 and two holding screws 1 that are used for fixing cross bar 2 and centering bar 3 positions by blade holding screw 10, this centering bar also is provided with the cup-shaped chassis 6 of a buried bearing 4 for 3 times, the lower surface on this chassis 6 is at 0 °, 120 °, be respectively arranged with a thimble 5 on 240 ° of three directions, in the cutting process, rotate together by centering bar 3 and bearing 4, the tangential force that thimble is not justified, can not produce eccentric phenomena, and the less easy control of exerting oneself, the pad precision of cutting is higher, centering bar 3 is an interference fit with bearing 4 endoporus, bearing 4 outer round surface and chassis 6 endoporus are interference fit, can not produce relative slip like this in the bearing rotation process.This device also comprises the bearing cap 7 of a band centre bore, and it can pass centering bar 3 and be installed on the end face of openend on chassis 6.
During operation, it is vertical with pad (not shown) surface originally to cut the pad apparatus.By regulating the holding screw 1 on centering bar 3 and the knife rest 8, make knife rest 8 and the centering bar 3 can move left and right, the scale (not shown) of adjusting on the cross bar 2 makes it equal pad internal diameter (or external diameter), fasten the holding screw 1 of core bar 3 and knife rest 8 then, the cross bar 2 that horizontally rotates knife rest 8 ends makes blade by predetermined track cutting pad.
Above embodiment is only for the usefulness of explanation the utility model, but not to the restriction of the utility model protection domain.Relevant those skilled in the art; under the situation that does not break away from spirit and scope of the present utility model; can also make various conversion or modification, and the technical scheme that all are equal to should belong to also within the category of the utility model protection, is limited by appended claim.
Claims (4)
1. cut the pad apparatus for one kind, comprise a cross bar, pass a knife rest of this cross bar and certain core bar, one respectively and be fixed in blade knife rest under and two by the blade holding screw and be used for fixing cross bar and the holding screws of the bar position of feeling relieved, it is characterized in that: also be provided with the cup-shaped chassis of a buried bearing under the described centering bar, the lower surface on this chassis is respectively arranged with a thimble on 0 °, 120 °, 240 ° three directions.
