Description
Technical field
The invention belongs to metal pipe working machine technical field, be specifically related to a kind of installation bearing seat of swing mechanism of cold-rolling pipe mill and the cooperating structure of transmission case.
Background technique
Cold pilger mill widely uses in tubing processing industry, and in Chinese patent literature no matter the weary technological scheme being seen in about cold pilger mill, the slightly continuous feeder of a kind of two cold mill pipe as disclosed in utility model patent notice of authorization CN201223884Y to exemplify, the achievement part of this scheme has solved the technical problem that the double-roller cold pilger mill that first has can not continuous operation, because, double-roller cold pilger mill in prior art is after having sent to, because feeding trolley can only withstand pipe rear end, the necessary rollback of feeding trolley is to home position (reset), be housed to next root pipe, the pipe that penetrates plug enters feeding trolley, after feeding trolley clamping pipe, start to send to, so there is one section of feeding trolley rollback and charging, the auxiliary setup times such as clamping, cause this cold pilger mill can not continuous operation, therefore this patent scheme can be increased work efficiency undoubtedly.And for example: the revolution feed mechanism of a kind of cold pilger mill that CN2788915Y recommends has the alleged technique effect of Instructions Page 2 14th～19 row of this patent.For another example: the cold pilger mill that CN2621094Y introduces send swirl gear to, this scheme is arranged between the head and feeding lathe bed of cold pilger mill sending swirl gear to, jack shaft system and the 2-level reducer of having cancelled the cold pilger mill in prior art, significantly reduce the floor space of cold pilger mill.
Except the above-mentioned technological scheme exemplifying, also just like CN2385817Y (feed mechanism of cold pilger mill), CN2386900Y (tube-rolling machine send to swirl gear), CN2656036Y (cold pilger mill is sent swirl gear to), CN201067762Y (electrical control is sent to and rotating novel tube-rolling machine), CN201470679U (steel pipe rotary feeding mechanism of tube-rolling machine), CN201543661U (a kind of revolution feed mechanism of double-roller cold pilger mill) and CN201592194U (hydraulic revolving feed device of cold pilger mill), etc.
Above mentionedly send the abbreviation that swirl gear is feed mechanism and swirl gear to, Zhe Liangge mechanism is the key mechanism of complete cold pilger mill, with regard to swirl gear, its responsibility of taking on is to make plug revolution, and it is mainly made up of transmission case and the chuck (also claiming claw disk) of being furnished with claw.In prior art, comprise disclosed patent scheme above, in the time that swirl gear is put to on-the-spot use, conventionally transmission case is directly installed on installation bearing seat, that is to say, take transmission case by installation bearing seat and be installed on the scene that uses.Because installation bearing seat is only fixed with it for transmission case, and do not there is the effect that the position of transmission case is adjusted, therefore, in the time transmission case will being adjusted, can only realize by the adjustment to installation bearing seat, thereby bring inconvenience to adjustment, and because installation bearing seat is not only heavy but also fix with using on-the-spot terrace or title basis, so, in the time adjusting, not only drop into manpower many, and, once move installation bearing seat position, there will be the problem not corresponding with the basis of previous preparation.
In view of this, be necessary that installation bearing seat to the swing mechanism of cold-rolling pipe mill in prior art and the cooperating structure of transmission case are improved, the applicant has carried out good try for this reason, finds a way to resolve the problem, and technological scheme described below produces raw under this background.
Summary of the invention
Task of the present invention be to provide a kind of contribute to make transmission case convenient adjustment and using on installation bearing seat ensure installation bearing seat be held in the position that initial and basis fix and can reduce input manpower while adjustment, improve regulate the speed and ensure the installation bearing seat of swing mechanism of cold-rolling pipe mill and the cooperating structure of transmission case of adjusting effect.
Task of the present invention completes like this, a kind of installation bearing seat of swing mechanism of cold-rolling pipe mill and the cooperating structure of transmission case, comprise a mounting support seat body and be arranged at the transmission case body on mounting support seat body, mounting support seat body comprises end fastening flange, before, after, left, right wallboard, before, after, left, right wallboard encloses square shape each other, and fix with end fastening flange, be characterised in that: also include one first casing adjusting seat and one second casing adjusting seat, the one end on first one end of casing adjusting seat and the upper edge of left wallboard is fixed, the one end on the upper edge of the other end and right wallboard is fixed, and with the side contacts of front panel towards rear wall plate, the other end on second one end of casing adjusting seat and the upper edge of left wallboard is fixed, and the other end on the upper edge of the other end and right wallboard is fixed, and with the side contacts of rear wall plate towards front panel, the length direction of the first casing adjusting seat and towards on a side offer one first casing adjustment tank, in the first casing adjustment tank, be equipped with movably at least one pair of first adjustment screw, the length direction of the second casing adjusting seat and towards on a side offer one second casing adjustment tank, in the second casing adjustment tank, be equipped with movably at least one pair of second adjustment screw, there is at least one first adjustment screw base in the upper of described left wallboard along extending to form, on the first adjustment screw base, be provided with the 3rd and adjust screw, there is at least one second adjustment screw base in the upper of described right wallboard along extending to form, on the second adjustment screw base, be provided with the 4th and adjust screw, described transmission case body each extension on the outer wall of a side of described front panel and on the outer wall of a side of described rear wall plate is fixed with at least one pair of transmission case fixed base, on each transmission case fixed base, offer transmission case and adjust screw hole, described first adjusts screw and described second adjusts screw and inserts that transmission case is adjusted screw hole and transmission case fixed base is fixed, and the 3rd described adjustment screw contacts with the left side wall of transmission case body, and the 4th described adjustment screw contacts with the right side wall of transmission case body.
In a specific embodiment of the present invention, the shape of cross section of the first described casing adjustment tank and the second described casing adjustment tank is T shape, the shape of bottom and the shape of the first casing adjustment tank of the first described adjustment screw are suitable, and the shape of bottom and the shape of the second casing adjustment tank of the second described adjustment screw are suitable.
Technological scheme provided by the invention is owing to having set up first, the second casing fixed base, first, on the second casing fixed base, offer respectively first, the second casing adjustment tank, done the adjustment of left and right directions by the second adjustment screw guarantee transmission case body in the adjustment screw of first in the first casing adjustment tank and the second casing adjustment tank, and after adjustment by the 3rd, the 4th adjustment screw is spacing, therefore can realize convenient adjustment of transmission case body on mounting support seat body, because saving without moving mounting support seat body the manpower that participates in adjustment, improve and regulate the speed and ensure adjustment effect.
