Three, summary of the invention:
Technical problem to be solved in the utility model is: propose a kind of simple in structurely, with low cost, reliable and stable, improve the slender axles processing bracket of machining accuracy.
The technical solution of the utility model is:
A kind of slender axles processing bracket, comprise base, be installed in the stop sleeve on the base, and be sleeved on the adjusting rod that is slidingly matched with stop sleeve in the supporting sleeve, the adjusting rod top is provided with bearing holder (housing, cover), fixing in the bearing holder (housing, cover) has bearing, and stop sleeve top is provided with at least one screw, and clamping bolt tightens up adjusting rod by screw.
Wherein, the screw edge on the stop sleeve is provided with the reinforcement boss.
Wherein, adjusting rod is a tubular structure, and is fixing with the bearing holder (housing, cover) welding.
Wherein, bearing holder (housing, cover) is a sleeve structure, and inwall is provided with step, and step side cooperates with the bearing outside side.
Wherein, the bearing inner sleeve interior diameter is greater than the processing major diameter.
The beneficial effects of the utility model are:
1, simple in structure.The utility model mainly comprises base, supporting follower three parts that height adjustment mechanism that adjusting rod, stop sleeve constitute and bearing holder (housing, cover), bearing constitute, the fixing stability that improves whole device of each several part welding, other is mechanical connection and fixes, the parts that relate to are few, and relation is simple.
2, with low cost.Because simple in structure, each parts all can adopt standard component processing to obtain except that bearing holder (housing, cover), each parts annexation is simple, low processing cost.
3, reliable and stable.Supporting structure of the present utility model, base and stop sleeve, adjusting rod and bearing holder (housing, cover) adopt welding fixing, improve the integral rigidity of device, bearing holder (housing, cover) is provided with interior step, guarantees bearing assembly precision and stability, adopt bearing suit mode holding workpieces, the assurance workpiece can not deviate from, and improves the reliability of device, avoids safety problem to take place.
4, improve machining accuracy.Adopt the supporting servo-actuated critical piece of bearing as carriage, the suit workpiece can weaken the vibration of workpiece effectively, and bearing inner sleeve rotates with axle spare, has reduced the friction of workpiece and carriage, and the rotating speed of retainer shaft part improves machining accuracy.
Four, description of drawings:
Fig. 1 faces structural representation for the utility model slender axles processing bracket;
Fig. 2 is the utility model slender axles processing bracket side-looking structural representation.
Five, the specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Referring to Fig. 1-Fig. 2, among the figure, the 1-base, the 2-stop sleeve, the 3-adjusting rod, the 4-bearing holder (housing, cover), the 5-bearing, the 6-screw, the 7-clamping bolt, 8-strengthens boss, step in the 9-bearing holder (housing, cover).
The utility model provides a kind of slender axles processing bracket, comprise base 1, be installed in the stop sleeve 2 on the base, and be sleeved on the adjusting rods 3 that are slidingly matched with supporting sleeve 2 in the stop sleeve 2, adjusting rod 3 tops are provided with bearing holder (housing, cover) 4, fixing in the bearing holder (housing, cover) 4 has bearing 5, stop sleeve top to be provided with at least one screw 6, and clamping bolt 7 tightens up adjusting rod 3 by screw 6.
Screw 6 edges on the stop sleeve 2 are provided with strengthens boss 8.
Adjusting rod 3 is a tubular structure, and is fixing with bearing holder (housing, cover) 4 welding.
