Abstract
The utility model discloses a supporting structure of a high-speed precision press, and belongs to the technical field of presses, aiming at solving the problem of the press in the prior art that the dynamic precision is poor, the bearing capability is less and the operation speed is low. The supporting structure comprises a supporting shaft and a supporting sleeve which is sleeved outside the supporting shaft, wherein counter bores are arranged in the inner walls at two ends of the supporting sleeve; rolling support bearings are sleeved between the counter bores and the peripheral wall of the bearing shaft; two end surfaces of the bearing sleeve are provided with bearing press covers through fastening bolts; a hydrostatic support bearing is arranged between the supporting shaft and the supporting sleeve, and is arranged between the inner-ring end surfaces of the two rolling support bearings; and an oil inlet channel is arranged on the supporting sleeve in the radial direction, and the oil inlet channel passes through the hydrostatic support bearing and is communicated with a gap between the supporting shaft and the hydrostatic support bearing. The supporting structure of the high-speed precision press has the advantages of high dynamic precision, high operation speed and strong bearing capability.
Description
Technical field
The utility model relates to a kind of supporting structure of forcing press, and particularly a kind of supporting structure of high-speed fine press belongs to the press technologies field.
Background technology
A kind of forcing press is arranged in the prior art; Its supporting structure comprises the splicing sleeve that bolster is outer with being sleeved on bolster; Splicing sleeve two ends inwall offers counterbore; Be set with the rolling bearing bearing between counterbore and the bolster outer circle wall, through trip bolt bearing gland be installed also on two end faces of splicing sleeve.In order to guarantee the bolster favorable rigidity, the affluence amount in the high-speed blanking press design is generally big than ordinary press, and this just makes the bolster diameter dimension more many greatly than the size of ordinary press.If only adopt the rolling bearing structure, though rotating speed is easy to improve, bearing capacity is lower, and dynamic accuracy is relatively poor; If only adopt sliding support structure, will inevitably strengthen the frictional resistance that produces in the process of running up, the insufficient lubrication between bolster and the splicing sleeve; Forcing press is when running up; The bolster load that frequently withstands shocks, the anti-fatigue ability of material and seizure resistance, compliance, embedding are hidden property and will inevitably be descended, though the supporting construction of rolling has relatively improved bearing capacity; But dynamic accuracy does not improve yet, and the precision retention time is not long.
The utility model content
The purpose of the utility model is to overcome deficiency of the prior art, and the supporting structure of the high-speed fine press that a kind of dynamic accuracy is high, the speed of service is fast, bearing capacity is strong is provided.
The purpose of the utility model is achieved in that the supporting structure of high-speed fine press; Comprise the splicing sleeve that bolster is outer with being sleeved on bolster; Said splicing sleeve two ends inwall offers counterbore, is set with the rolling bearing bearing between counterbore and the bolster outer circle wall; Through trip bolt bearing gland is installed also on two end faces of said splicing sleeve, also is provided with the hydrostatic support bearing between said bolster and the splicing sleeve, said hydrostatic support bearing is arranged between the interior ring end face of two rolling bearing bearings; Radially offer oil inlet passage on the said splicing sleeve, said oil inlet passage run through the hydrostatic support bearing and connect bolster and the hydrostatic support bearing between the gap.
Keep certain clearance between hydrostatic support bearing and the bolster, when lathe dry run and idle stroke, contact hardly between hydrostatic support bearing and the bolster, avoid taking place sliding friction.Oil inlet passage can external static pressure fuel tank, and lubricating oil injects the gap between bolster and the hydrostatic support bearing and forms oil film through oil inlet passage, and the coefficient of friction between reduction bolster and the hydrostatic support bearing reduces wear, and effectively prolongs the precision retention time.In punching course, the rolling bearing bearing load that at first withstands shocks, small strain takes place after, with hydrostatic support bearing bearing load, have higher capacity, and can adapt to running up of forcing press.The utility model is applied to can effectively improve on the forcing press reliability, running precision, speed and the service life of machine tool running, and its compact conformation is convenient to marketing and is used.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Wherein, 1 bolster; 2 splicing sleeves; 3 counterbores; 4 rolling bearing bearings; 5 trip bolts; 6 bearing glands; 7 hydrostatic support bearings; 8 oil inlet passages.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
As shown in Figure 1; Be the structural representation of the utility model, the supporting structure of high-speed fine press comprises bolster 1 and the splicing sleeve 2 that is sleeved on outside the bolster 1; Splicing sleeve 2 two ends inwalls offer counterbore 3, are set with rolling bearing bearing 4 between counterbore 3 and bolster 1 outer circle wall; Through trip bolt 5 bearing gland 6 is installed also on two end faces of splicing sleeve 2, also is provided with hydrostatic support bearing 7 between bolster 1 and the splicing sleeve 2, hydrostatic support bearing 7 is arranged between the interior ring end face of two rolling bearing bearings 4; Radially offer oil inlet passage 8 on the splicing sleeve 2, oil inlet passage 8 run through hydrostatic support bearing 7 and connect bolster 1 and hydrostatic support bearing 7 between the gap.
The utility model is not limited to the foregoing description; On the basis of the disclosed technical scheme of the utility model; Those skilled in the art is according to disclosed technology contents; Do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the protection domain of the utility model.
