Abstract
The utility model discloses a mill housing, comprising a frame provided with a window, and a lead screw down locating device installed at the upper part of the frame; the locating device comprises a screwdown nut base fixedly connected with the frame at the top of the window, and a screwdown nut installed in the inner chamber of the screwdown nut base and matched with the screwdown lead screw; a fixed connecting piece is installed between the screwdown nut base and the screwdown nut; and reinforcement plates are installed at both sides of the lead screw upwards along with the screwdown nut base. The mill housing has the following advantages that the screwdown nut base fixedly connected with the frame at the top of the window is fixedly connected integrally by welding, the screwdown nut is installed in the inner chamber of the nut base, and the reinforcement plates are installed at both sides of the lead screw above the screwdown nut base, thereby having the advantages such as integrality of casting frame and high strength and high rigidity of general cutting frame; and the mill housing is convenient to process, thereby shortening processing period and decreasing processing cost.
Description
Technical field
The utility model relates to milling train, especially relates to a kind of nut screw mandrel that uses and vertically depresses the used mill housing of mode.
Background technology
The frame tradition of mill housing is a cast structure, if screw box and frame integrally casting come out, not only is easy to generate casting flaw, cause intensity not high, and the production cycle is long, and processing capacity is big, and outward appearance is comparatively coarse.If screw box is made separately, because the external diameter of nut is bigger, directly be embedded in the globality that the frame upper beam has destroyed frame, slackened intensity, the rigidity of frame greatly.Traditional like this nut screw mandrel is depressed mode and can't be used safely.
The utility model content
The purpose of this utility model is to provide a kind of good integrity and intensity height, mill housing that rigidity is high.
For achieving the above object, the utility model can be taked following technical proposals:
Mill housing described in the utility model, the screw mandrel that comprises the frame that offers window and be arranged on described upper rack presses down positioner, described positioner is the screw box seat that is connected on the frame of window top, with be arranged in the described screw box seat inner chamber with depress the screw box that screw mandrel is complementary, between described screw box seat and screw box, be provided with fixed connecting piece; The screw mandrel both sides that make progress along described screw box seat are provided with stiffener.
Described fixed connecting piece is the pressing plate that is arranged on screw box seat and screw box junction.
Between described screw mandrel and stiffener, be provided with fairlead.
Advantage of the present utility model is the screw box seat (it being fixed with one by welding manner) that is connected on the frame of window top, screw box is arranged in the nut seat inner chamber, the screw mandrel both sides that make progress at the screw box seat are provided with stiffener, the globality and the advantages such as the high strength of common cutting frame, high rigidity of casting frame had so both been taken into account, be convenient to processing again, shorten the process-cycle, reduced processing cost.
Pressing plate in screw box seat and the setting of screw box junction has played the connection positioning action, is convenient to again simultaneously install.
Be provided with fairlead between screw mandrel and the stiffener, made things convenient for the welding location between stiffener and the screw box seat.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be Figure 1A-A to the sectional structure schematic diagram.
Fig. 3 be Figure 1B-B to the sectional structure schematic diagram.
The specific embodiment
As Figure 1-3, mill housing described in the utility model, the screw box seat 5 that comprises the frame 4 that offers window and be arranged on the welding of described frame 4 window tops, with be arranged in described screw box seat 5 inner chambers with depress the screw box 6 that screw mandrel 1 is complementary, the junction between described screw box seat 5 and screw box 6 is provided with and connects pressing plate 7; Frame 4 both sides that make progress along described screw box seat 5 are welded with stiffener 2,3.
Claims (2)
1. mill housing, comprise frame (4) that offers window and the screw mandrel (1) that is arranged on described frame (4) top, it is characterized in that: described positioner is for being connected in the screw box seat (5) on the window top frame (2), with be arranged in described screw box seat (5) inner chamber with depress the screw box (6) that screw mandrel (4) is complementary, between described screw box seat (5) and screw box (6), connect by pressing plate (7); Screw mandrel (4) both sides that make progress along described screw box seat (5) are provided with stiffener (6).
2. mill housing according to claim 1 is characterized in that: described fixed connecting piece is for being arranged on screw box seat (3) and frame (4) welding.
