Abstract
The utility model relates to a C-shaped centre frame of a horizontal lathe. The utility model comprises a centre frame upper body, a centre frame lower body, sliding bodies arranged in sliding grooves of the upper body and the lower body, a shaft and a roller. The utility model is characterized in that the centre frame upper body and the centre frame lower body are connected through a key groove; a pair of kinematic pairs which converts rotary motion to linear translation is arranged between the centre frame upper body and the centre frame lower body which are locked together through a stopping positioning pin. The kinematic pairs can be a gear rack arranged at the center frame upper body and a gear shaft arranged at the center frame lower body and engaged with the gear rack and can also be a screw rod arranged at the center frame upper body and a nut seat arranged at the center frame lower body and screwed with the screw rod; the gear shaft or the nut seat is rotated so as to realize the slippage of the center frame upper body. The C-shaped centre frame changes the tilting motion of the traditional centre frame upper body to sliding motion so as to conveniently realize the opening and the closing of the centre frame when workpieces are loaded and unloaded on high-duty and large-scale horizontal lathes, the labor intensity is reduced and the production efficiency is improved.
Description
Technical field the utility model belongs to the bracing or strutting arrangement of field of machining workpiece, relates in particular to a kind of Horizontal LaCommutating C-shaped Center Rest.
The centre frame great majority of using on the existing horizontal lathe of background technology are closed types, and the upper body of centre frame connects by bearing pin with lower body one side, the fastening lower body on it of opposite side usefulness bolt, nut; Or the upper body of centre frame and lower body locate by alignment pin, and both sides are with the fastening lower body on it of bolt, nut.When workpiece loading and unloading, opening of centre frame upper body is to open by upset or lifting upper body, and it is more extensive that this structure is used on horizontal lathe.Along with fast development of modern industry, all trades and professions are more and more to demand heavy, the large-size horizontal lathe, but original centre frame of this lathe configuration, when workpiece loading and unloading, labour intensity is big, and production efficiency is low, obviously can not satisfy the new market demand.
The shortcoming that the summary of the invention the purpose of this utility model is to overcome existing centre frame when using on heavy, large-size horizontal lathe, a kind of loading and unloading that can realize workpiece easily are provided, alleviate labor strength, the Horizontal LaCommutating C-shaped Center Rest of enhancing productivity.
For achieving the above object, the technical scheme that the utility model is taked is: this Horizontal LaCommutating C-shaped Center Rest comprises centre frame upper body and lower body, is located at gliding mass, axle and roller in each sliding tray of lower body, it is characterized in that being connected by the keyway mode between centre frame upper body and the lower body, be provided with a pair of will rotatablely moving therebetween and be converted into the kinematic pair that straight line moves, the centre frame upper and lower body is locked together in together by the stop shop bolt.
Above-mentioned kinematic pair is mounted in the tooth bar of centre frame upper body and the gear shaft that is installed in lower body and is meshed with tooth bar, by the turning gear wheel shaft, realizes the slippage of centre frame upper body.
Above-mentioned kinematic pair is mounted in the screw rod of centre frame upper body and the nut seat that is installed in lower body and screws with screw rod, by the rotating nut seat, realizes the slippage of centre frame upper body.
Above-mentioned centre frame upper body and lower body are respectively equipped with stop dog, with the slippage stroke of restriction centre frame upper body.
The above-mentioned Horizontal LaCommutating C-shaped Center Rest that the utility model provides, the flip-flop movement of traditional centre frame upper body is improved to sliding motion, thereby realized centre frame opening during workpiece loading and unloading on heavy, large-size horizontal lathe easily with closed, alleviate working strength of workers, improved production efficiency.
Description of drawings Fig. 1 is a C shape centre frame structural representation;
Fig. 2 is the right view of Fig. 1.
Among the figure: 1-centre frame upper body; 2-stop shop bolt; 3-centre frame lower body; The 4-stop dog; The 5-roller; The 6-tooth bar; The 7-gear shaft; 8-base gear axle; The 9-gliding mass; The 10-axle; The 11-pressing plate.
The specific embodiment as shown in Figure 1 and Figure 2, this C shape centre frame comprises centre frame upper body 1 and lower body 3, is located at gliding mass 9, axle 10 and roller 5 in lower body 1,3 each sliding tray, be connected by the keyway mode between centre frame upper body 1 and the lower body 3, be installed in the tooth bar 6 of centre frame upper body 1 and be installed in the gear shaft that is meshed with it 7 of lower body 3, lower body 1,3 is locked together in together by the stop shop bolt on the centre frame.
This C shape centre frame can be along the machine tool guideway follow rest by rotating base gear shaft 8, and fastening bolt, nut make pressing plate 11 compress the machine tool guideway lower plane, thus back rest.Its slipping is: dialled stop shop bolt 2, centre frame upper body 1 and lower body 3 can be relatively moved, then by rotary teeth wheel shaft 7 pinion racks 6, moved along dovetail guide thereby drive centre frame upper body 1, so easily workpiece loading and unloading.After workpiece installed, turning cylinder 10 drove gliding mass 9 and moves in lower body 1,3 each sliding tray on centre frame, made three rollers 5 respectively by the outer surface of tangible processing work, so that processing work.
The slippage of the relative lower body in upper body of above-mentioned C shape centre frame is to lean on the mode of gear shaft pinion rack to realize, under same mentality of designing, can also adopt screw rod to be installed in the upper body of centre frame, nut seat is installed in the lower body of centre frame, by screwing of screw rod and nut seat, to rotatablely move is converted into rectilinear motion, can realize the slippage of the relative lower body in centre frame upper body equally, thus workpiece loading and unloading easily.
