Abstract
The utility model discloses a tight mechanism in pull rod top, including the reinforcement pole, the lower extreme of reinforcement pole is provided with down the nut, and the upper end has set gradually interior nut and outer nut outside by interior, and the lower extreme that is pushing up the interior nut is provided with the piston, is pushing up outer nut lower extreme and is hugging closely the piston and be provided with the oil pressure jar, is provided with the oil blanket at the seam crossing of piston and oil pressure jar, is hugging closely the oil pressure jar at the piston lower extreme and is provided with solid fixed ring. Connect fixed lathe easy dismounting through this product, if produce the clearance in time between each part moreover and consolidate the connection.
Description
Technical field
The utility model relates to a kind of machine tool mechanical art, especially relates to a kind of pull rod pressing mechanism that applies to lathe.
Background technology
The bindiny mechanism of traditional machine tool comprises: reinforcing bar and the nut that is installed in the reinforcing bar two ends constitute; Earlier each parts of lathe are serially connected by reinforcing bar during installation, utilize the two ends nut of reinforcing bar that lathe is locked then, but in making, the process that rotary nut is locked each parts must allow reinforcing bar produce thermal expansion, and then make reinforcing bar produce the elastic stretching distortion, treat that each parts of reinforcing bar cooling contraction back lathe could be connected and fixed closely.Though this connected mode can firmly also exist following what time not enough:
1, difficulty is installed;
Need to change if 2 machine tool components damage, can only carry out the destructiveness dismounting by external force, therefore dismounting is extremely inconvenient;
If 3 lathes because of the external force effect produces vibration or thermal deformation, make and produce gap or relative displacement between the lathe each several part, also can't closely link to each other each several part once more by nut or other way again.
Summary of the invention
At the problems referred to above, the utility model provides a kind of and has made each parts easy disassembly of lathe, connects close and firm and can in time reinforce the pull rod pressing mechanism that connects between each parts.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
A kind of pull rod pressing mechanism, comprise reinforcing bar, the lower end of reinforcing bar is provided with down nut, the upper end is provided with interior nut, exterior nut cap has been threaded on the interior nut, the oil hydraulic cylinder that piston is installed and cooperates on the reinforcing bar of interior nut below with piston, an end roof pressure of piston is in the lower surface of interior nut, and the end face of oil hydraulic cylinder contacts with the lower surface of exterior nut cap.
Further, be provided with oil sealing, be close to oil hydraulic cylinder in the piston lower end and be provided with retainer ring at the seam crossing of piston and oil hydraulic cylinder.
The beneficial effects of the utility model are: the utility model is serially connected each parts of lathe by reinforcing bar, nut under the installation of the lower end of reinforcing bar, the upper end closely is connected and fixed each parts of lathe by cooperatively interacting of parts such as interior nut, exterior nut cap, piston, oil hydraulic cylinders; This pull rod pressing mechanism not only can make each parts of lathe closely connect, and dismounting is also very convenient, and if produce the gap between each parts and also can in time reinforce the connection.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is the vertical view of the utility model embodiment;
Fig. 2 is the cutaway view along A-A among Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of pull rod pressing mechanism that the utility model is introduced, comprise reinforcing bar 1, the lower end of reinforcing bar 1 is provided with down nut 2, nut 3 in the upper end is provided with, the exterior nut cap 4 that has been threaded on the interior nut, the oil hydraulic cylinder 6 that piston 5 is installed on the reinforcing bar of interior nut 3 belows and cooperates with piston 5, one end roof pressure of piston 5 is in the lower surface of interior nut 3, and the end face of oil hydraulic cylinder 5 contacts with the lower surface of exterior nut cap 4.
Seam crossing at described piston 5 and oil hydraulic cylinder 6 is provided with oil sealing 7, prevents that the oil that injects is penetrated into the outside, is close to oil hydraulic cylinder 6 in piston 5 lower ends and is provided with retainer ring 8.
The working method of the pull rod pressing mechanism of the utility model embodiment is described in detail as follows:
At first each parts (base of lathe, fuselage, important actor, footstock etc.) be sleeved on the reinforcing bar 1, by nut 3 in screwing, exterior nut cap 4 reaches down, and nut 2 tentatively is fixed together each parts of lathe, then toward oil hydraulic cylinder 6 interior oilings, along with the increase of injecting oil mass forces reinforcing bar 1 to produce elastic deformation under the effect of internal stress, thereby make the small gap of generation between exterior nut cap 4 and the oil hydraulic cylinder 6, and then by rotation exterior nut cap 4 elimination this gap, the oil in the oil hydraulic cylinder 6 is bled off afterwards, each parts that so just can make lathe are being fixed together of close and firm more again.The lathe easy accessibility that is connected and fixed by this pull rod pressing mechanism, and if produce between each parts the gap can by above-mentioned in the oil hydraulic cylinder 6 mode of oilings in time reinforce the connection.
More than be that preferable enforcement of the present utility model is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
