For overcome existing side bearing manufacturing procedure loaded down with trivial details, need multiple bearing to be installed, deficiency that production efficiency is low, the invention provides a kind of side bearing processing technology and frock used, adopt this technique and frock processing side bearing, operation is simple, mount is convenient, and can improve one times of output.
Technical scheme of the present invention is: a kind of side bearing processing technology, is characterized in that comprising the following steps:
(1), adopt circular disc milling machine processing work bottom surface;
(2), adopt double column milling machine processing work left side and right side;
(3), several are fixed on machining center by frock by the finished workpiece of above-mentioned steps (two), then carry out following operation successively,
1., type bottom surface in milling;
2., milling the right groove;
3., the left inside side of milling, right inside side, then by workpiece pressure-air cooling;
4., in finish-milling before, interior after, and guarantee that both sides wall thickness is even;
5., the left facade of finish-milling, right facade.
A kind of above-mentioned side bearing processing technology frock used, comprise base plate, on described base plate, along continuous straight runs has two row's screwed holes, in screwed hole, by double end clamping bolt, be connected with clamping kit, described plate upper surface bottom is fixed with the baffle plate of horizontal direction, is fixed with several perpendicular to the side block piece of baffle plate on the base plate on baffle plate top.
Described clamping kit comprises riser and flat board, riser and dull and stereotyped vertical welding, and described dull and stereotyped bottom is inverted U-shaped, and dull and stereotyped middle part has the strip hole of vertical direction.
The present invention has following beneficial effect: owing to taking such scheme, after by three base surface processing, adopt Cutter Body Processing with Machining Center side bearing, only need one-time positioning to be installed, just can realize multiple working procedure, operation is simplified greatly, improved working (machining) efficiency, known by long-time application, in same time, can improve one times of output, also avoid frequently changing frock and lathe and increase product size tolerance, improved crudy simultaneously.The tool structure of visiting process using is simple, can process a plurality of workpiece simultaneously, and location is simple, easy to operate.

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
By shown in Fig. 1 to Fig. 4, a kind of side bearing processing technology, comprises the following steps:
(1), adopt circular disc milling machine processing work bottom surface A, assurance workpiece overall height h, and the slide measure that is 0-150mm by specification check;
(2), adopt double column milling machine processing work left side B and right side C, guarantee workpiece overall length L1 and the long L2 of right openings, and with the slide measure that specification is 0-150mm and 0-300mm, check respectively;
(3), according to the groove position needs of frock, several are fixed on machining center by frock by the finished workpiece of above-mentioned steps (two), workpiece is placed on base plate 3, and by side block piece 6 and baffle plate 7 location, then by double end clamping bolt 4, workpiece is fixed, precedence is carried out following operation again
1., type bottom surface D in milling, high h2 in guaranteeing, and the slide measure that is 0-150mm with specification is checked;
2., working groove I, guarantee groove width L3, the right side height h3 to the long L4 of groove center and bottom land to inner type bottom surface D, and the slide measure that is 0-150mm by specification is checked;
3., the left inside side J of milling, right inside side K, length L 5 between the height h5 of the assurance high h4 of size inboard wall groove and Zhi Lixing bottom surface, inboard wall groove bottom surface, two medial surfaces, and guarantee that between two medial surfaces, length L 5 is 1.5mm with respect to Central Symmetry degree, then by workpiece with pressure-air cooling to normal temperature, its objective is and prevent that the high temperature that processing produces from making workpiece produce distortion, prevent that form and position tolerance is overproof, high temperature cannot guarantee that the accurately machined size of subsequent processing is accurate;
4., F, interior G below above in finish-milling, and guarantee both sides wall thickness evenly and be not less than 6mm, guarantee workpiece inner width L6, and the slide measure that is 0-150mm with specification is checked;
