Description
Technical field
The utility model belongs to mechanical engineering technical field, relates to a kind of column tensioning adjusting device, is applicable to solve column tensioning, anti-rotation that is similar to the extension shaft for rolling mill carriage and the problem of highly regulating, and realizes accurate height/length location.
Background technology
In the metallurgy rolling industry, because the wearing and tearing of rolling mill roll are very serious, need often to change roll and repair apparatus etc., and the general all direct extension shaft for rolling mill with several tons of weights of roll is associated in, so the time just need special equipment accept extension shaft for rolling mill, and extension shaft for rolling mill accurately located, with the installation that makes things convenient for roll with shift out.The existing carriage of accepting extension shaft for rolling mill usually has pillar construction, its conventional mounting pattern as shown in Figure 1, column is fixed on/following fixed frame on, on/following fixed frame is connected with other associated part again, the most of moving component that connects in the shaft tray all is installed on the column, column its axially and the power of radially bearing and moment bigger, the problem that this structure exists is: 1) because column uses hold-down screw to be connected with fixed frame up and down respectively, therefore the length of column to required precision very accurate, otherwise column meeting play up and down when being subjected to axial force; 2) because last/lower bearing bracket is fixed at the other end, under the effect that hold-down screw is tightened, frame can be subjected to the moment of flexure effect in various degree, influences the stability of total; 3) column also can rotate when being subjected to radially moment, and column attachment screw up and down will bear shearing force, and will be very unfavorable to the security of screw.
In order to address the above problem, the accuracy of manufacture requirement of column and cooperation parts thereof is very high usually, makes manufacturing cost just increase in the tradition.And after in a single day this connected mode designed, column was exposed at the outer length of fixed frame with regard to relative fixed, and the locus of installing on column and moving up and down for other parts is also just fixed accordingly, if will increase this space, just must take carriage apart, increase pad, operation is loaded down with trivial details.
Summary of the invention
The purpose of this utility model is to provide a kind of can carry out column Height Adjustment, tensioning, prevent the column tumbler, can realize the accurate height/length of extension shaft for rolling mill location, and the accuracy of manufacture that reduces column and cooperation parts thereof, cost is low, and is simple in structure, safe and reliable, easy to maintenance.
The utility model adopts such technical scheme to realize, column tensioning adjusting device comprises, following fixed frame and being installed in, column in the following fixed frame installing hole, be placed on the adjustment pad and the hold-down screw of column termination, it is characterized in that: between column termination and fixed frame, slide plate is installed successively, on, following wedged plate, adjust pad, slide plate is fixed in the slide plate installing hole of fixed frame, last wedged plate is connected with the adjustment screw that passes the fixed frame sidewall, following wedged plate is connected the surface of last wedged plate and slide plate with the adjustment pad with column by hold-down screw, the wedge surface of following wedged plate is slidingly matched.
In the said apparatus, slide plate, following wedged plate, last wedged plate, adjustment pad, adjustment screw etc. can be installed in of column, also can install simultaneously at column two.
Described fixed frame inside is provided with the column installing hole, is used for column the location is installed.
Fixed frame one side that slide plate is installed, also be provided with the slide plate installing hole behind its frame internal upright installing hole, the degree of depth of slide plate installing hole is less than slide plate thickness, and slide plate is installed its surface, back and is exceeded the inside, column installing hole hole.
For tensioning and the highly adjusting that realizes column, be provided with between column and the fixed frame, following wedged plate, adjust pad. on described, the lozenges of following wedged plate is slidingly matched, the angle of two wedged plate lozenges is identical, 15 °～30 ° of angle preferable range. go up wedged plate by passing the adjustment screw of frame side wall, be fixed on the fixed frame on axially at column. after connecing shaft tray and installing, owing to reasons such as foozles, on, lozenges between the following wedge be do not have close-fitting, column becomes flexible on it is axial, promoting to go up wedged plate by rotation adjustment screw moves along lozenges, in the change/following wedged plate binding site each other, realize closely cooperating between the wedged plate, reach the purpose that tensioning and column height are regulated.
In last wedged plate moving process, produce friction with fixed support, between last wedged plate and fixed support, be provided with slide plate, the size of slide plate should guarantee that wedge can contact with sled surface and can slide mutually, slide plate is screwed in the slide plate installing hole of fixed support inside, can change easily.
Be provided with the adjustment pad between following wedged plate and the column, when column that needs change is exposed at/length outside the following fixed frame, when having surpassed the maximal regulated scope of wedged plate, only needing just can increase this space by changing the thickness of adjusting pad easily, need not take carriage apart, make simple, convenient.
Since wedged plate up and down by slide plate with adjust pad and live surely, and the mating reaction of lozenges, wedged plate can not rotate mutually, makes the column can't be along its axial rotation, so also realized the anti-rotation effect.
The utility model is by being provided with the rotation that the wedge-like engagement face has prevented column, and by regulate the position of wedged plate with the adjustment bolt, column is realized tensioning and highly regulated, and eliminates foozle, reduces processing request, thereby reduces manufacturing cost; Establishing the adjustment pad between wedged plate and the column down simultaneously, can adjust column easily and be exposed at the outer length of fixed frame.This apparatus structure is simple, cost is low, safe and reliable, easy to maintenance.
