Description
technical field
The utility model relates to machine tool field, is specifically related to a kind of voussoir detent mechanism.
Background technology
Main straight pin and the two kinds of modes of taper bolt of adopting in current domestic docking lathe bed location.
Due to 1, the interference of straight pin utilization trace is fixed in pin-and-hole, through after mounting or dismounting repeatedly, the tightness of connection and precision reduce; 2, taper bolt is more convenient than straight pin in mounting or dismounting, but need join and bore and align reaming at erecting yard, and because processing environment is poor, the circular cone pin-and-hole precision of align reaming is low.
Cylinder pin hole is to process in advance; Straight pin is to do fine positioning in theory, but in practical application, often can be subject to the impact of the accuracy of manufacture, does not have positioning action.Straight pin utilizes small shrink to be fixed in articulation hole simultaneously, for guaranteeing positioning precision, should not often dismantle.
General accurate location adopts and manufactures circular cone pin-and-hole; Self-locking performance is good, positioning precision is high, easy for installation, repeatedly install and remove the impact of positioning precision less, but be generally to join again and make taper pin-hole after lathe bed assembles, due to site environment reason, can only join and ream with swing arm brill or power drill, the tapering of taper pin-hole differs surely and to guarantee like this, and in actual production, taper pin-hole and taper pin contact area should reach more than 80% just qualified, so cause positioning precision unstable.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provide a kind of simple in structure, a kind of voussoir detent mechanism reasonable in design, easy to use, it adopts one group of skewback, by adjusting the position that puts in, stretches out of skewback, makes to dock lathe bed and is accurately located; Location employing face contact, contact good rigidly, positioning precision is high, and bearing capacity is large, and repeatedly dismounting does not affect positioning precision, convenient and reliable.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of voussoir detent mechanism described in the utility model, comprise location keyseat, support voussoir, locate voussoir, cushion block, described location keyseat is fastened in lathe bed groove by location keyseat set bolt, and with supporting voussoir jam-pack, side outside described location voussoir and the two sides of lathe bed locating slot fit tightly, voussoir is supported in medial surface outside the voussoir of location extruding laminating, described cushion block is contained on the voussoir of location, and push down by briquetting, described briquetting is being located on keyseat by briquetting bolt-connection.
Further, described lathe bed is divided into forward and backward lathe bed, and by front and back lathe bed, connecting bolt is connected into an integral body by front and back lathe bed.
Further, described lathe bed groove totally 3 places.
Further, on described location voussoir, be provided with inclined-plane.
Further, the inclined-plane on described location voussoir can match with supporting voussoir inclined-plane, thereby to the closely fixing effect of extruding of location keyseat.
Adopt after said structure, the utility model beneficial effect is: its lathe bed of the utility model docking voussoir detent mechanism has adopted the face contact of voussoir, has strengthened the contact rigidity of locating surface, strengthens bending resistance, anti-twisting property; Can repeatedly dismantle, easy to operate, location is reliable; Improve the positioning precision of lathe docking lathe bed; Increase work efficiency and reduce the assembling and setting time.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the part-structure schematic diagram of lathe bed;
Description of reference numerals:
1, front lathe bed; 2, rear lathe bed; 3, front and back lathe bed is to connecting bolt 4, support voussoir; 5, briquetting bolt; 6, location keyseat 1; 7, location voussoir; 8, cushion block; 9, pressing plate; 10, cushion block housing screw and nut; 11, location keyseat set bolt; 12, line slideway; 13, line slideway relative motion face (everywhere).
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, 2, a kind of voussoir detent mechanism described in the utility model, comprise location keyseat 6, support voussoir 4, locate voussoir 7, cushion block 8, described location keyseat 6 is fastened in lathe bed groove by location keyseat set bolt 11, and with supporting voussoir 4 jam-packs, side outside described location voussoir 7 and the two sides of lathe bed locating slot fit tightly, voussoir 4 is supported in medial surface outside the voussoir 7 of location extruding laminating, described cushion block 8 is contained on the voussoir 7 of location, and push down by briquetting, described briquetting is connected on the keyseat 6 of location by briquetting bolt 5.
Described lathe bed is divided into front 1, rear lathe bed 2, and by front and back lathe bed, connecting bolt 3 is connected into an integral body by front 1 rear lathe bed 2.
Described lathe bed groove is totally 3 places.
On described location voussoir 7, be provided with inclined-plane.
Inclined-plane on described location voussoir 7 can match with supporting voussoir 4 inclined-planes, thereby to the closely fixing effect of extruding of location keyseat 6.
In use, the present invention is mainly docked location to large stroke lathe bed to the utility model.Front 1, rear lathe bed 2 processes locating slot before assembling, first keyseat 1 use location keyseat set bolt 11 in location is fastened on to (totally three groups) in rear lathe bed 2 grooves, and with support voussoir 4 jam-packs; Front 1, rear lathe bed 2 are hung at and are adjusted on Zhi Tie.First with slide block, test rod, the amesdial of two side line rails on front 1, rear lathe bed 2, line slideway relative motion face 13 is proofreaied and correct, guarantee two guide pass that amesdial shows at the numerical value of both direction all within the scope of 0.01mm; Then before and after tightening, lathe bed is to connecting bolt 3; Then filling in location voussoir 7 fits tightly the two sides of locating voussoir 7 and front lathe bed locating slot by locating the adjustment on the inclined-plane of voussoir 7; Be loaded on cushion block 8; Finally briquetting 4 use briquetting bolts 5 are connected in to location keyseat 6, regulate cushion block 8 housing screws by cushion block 8 and locate voussoir 7 and support voussoir 4 jails, top, and with nut, its cushion block 8 housing screws being locked.This kind location technology is easy to adjust, location is reliable.
