Abstract
The utility model relates to an external circular grinding bearing block, which comprises a base. A semicircular arc-shaped bearing block is arranged above the base, a semicircular arc-shaped gland is arranged above the semicircular arc-shaped bearing block, the semicircular arc-shaped bearing block and the semicircular arc-shaped gland form a circular bearing block, one end of the gland is arranged on the base through a fixing shaft, and the other end of the gland is connected with the base through a bolt. When the utility model is used, the two ends of the shaft to be processed are sleeved in the bearing block, the bearing sleeve is added, and the screw length of the bolt is adjusted and then set, so that the positions of the processed shaft and the processing device can be maintained stable, thereby improving the product processing accuracy. The utility model has the advantages of simple structure, convenient operation, stable clamping and free adjustment.
Description
[technical field]
The utility model belongs to the machining equipment technical field, relates to a kind of axle of processing and position between the processing apparatus of making and keeps peripheral milling bearing block stable, that can improve the machining accuracy of product.
[background technology]
Grinding machine is a kind of machining equipment, two ends above existing Grinder bench are separately installed with the center thimble, when processing work, the two ends of workpiece are respectively by center thimble fixed clamp, and the position by adjustment center thimble is to adjust the position of workpiece, make the suitable distance of maintenance between processing work and the processing apparatus, reach the purpose of reasonable processing; But above-mentioned this method by center thimble fixed clamp processing work exists following shortcoming: the one, when taking place to become flexible between the center at two ends thimble and the processing work, because top power is loosened, processing work is subjected to displacement, seriously influences machining accuracy; Be exactly the effect that has power between processing work and the processing apparatus in addition, under the effect of this power, processing work be subjected to displacement, thereby influenced the stability of processing, reduced the machining accuracy of workpiece; Because the hardness of processing work is not enough, makes and take place between center thimble and the processing work to become flexible in addition, also can influence the stability of processing, the machining accuracy of workpiece is reduced.
[utility model content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provide a kind of have simple in structure, easy to operate, clamping firm and regulate freely advantage, can improve the stability of processing and the peripheral milling bearing block of processing precision of products.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of peripheral milling bearing block, base is arranged, above base, be provided with a semicircular arc bearing block, the gland of a semicircular arc is housed above this semicircular arc bearing block, the gland of semicircular arc bearing block and semicircular arc constitutes a circular hole bearing block, one end of gland is installed on the base by fixed axis, and the other end of gland is connected with base by bolt.
Below described base, be provided with draw-in groove.
Side at described base is equipped with set bolt, and the screw rod of this set bolt passes the interior bolt hole of base to the bolt slot of base below, and the two ends of screw rod are bolted with nut respectively.
The beneficial effects of the utility model are: the two ends of the axle that will process are sleeved in the circular hole bearing block, and by installing the spiro rod length of bearing holder (housing, cover) and adjustment set bolt additional, make the axle and the position between the processing apparatus of processing keep stable, improved the machining accuracy of product, it is firm and regulate freely advantage to have simple in structure, easy to operate a, clamping.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-base, 2-gland, 3-semicircular arc bearing block, 4-set bolt, 5-draw-in groove, 6-bolt slot, 7-screw rod, 8-bearing holder (housing, cover), 9-fixed axis, 10-bolt.
[specific embodiment]
Below in conjunction with drawings and Examples the utility model is further specified:
Referring to Fig. 1, a kind of peripheral milling bearing block, base 1 is arranged, above base 1, be provided with a semicircular arc bearing block 3, the gland 2 of a semicircular arc is housed above this semicircular arc bearing block 3, semicircular arc bearing block 3 constitutes a circular hole bearing block with the gland 2 of semicircular arc, and an end of gland 2 is installed on the base 1 by fixed axis 9, and the other end of gland 2 is connected with base 1 by bolt 10; When real work, the utility model uses in pairs, earlier the utility model is placed on the workbench of cylindrical grinder, the two ends of processing work such as axle are respectively charged in the circular hole bearing block, if the diameter of axle less than circular hole bearing block internal diameter, then installs bearing holder (housing, cover) 8 additional in the outside of axle, the size of the axle that has installed bearing holder (housing, cover) 8 additional and the size of bearing block are adapted, and then gland 2 closed tightly, gland 2 usefulness bolts 10 are fastened on the base 1; Below base 1, be provided with draw-in groove 5, during work, make the edge of table of the utility model and cylindrical grinder workbench match fixing by the draw-in groove on the base 15; Side at base 1 is equipped with set bolt 4, the bolt hole that the screw rod 7 of this set bolt 4 passes in the base 1 extends in the bolt slot 6 of base 1 below, the two ends of screw rod 7 are bolted with nut respectively, by regulate this set bolt 4 screw rod 7 installation sites of length adjustment the utility model on workbench, reach the purpose of adjusting the workpiece position.Adopt the utility model, improved the stability of workpiece, improved the precision of product.
