Abstract
The utility model relates to a press fitting device for interference assembling, which comprises a press machine, a microcomputer control device, a pressure sensor, a position sensor and a connecting snap ring, wherein the pressure sensor inputs detected pressure signals into the microcomputer control device, the position sensor detects the displacement of a main shaft through the connecting snap ring, and inputs detected displacement signals into the microcomputer control device, the microcomputer control device compares received pressure values and received displacement values with a preset theoretical changing curve between displacement and pressure, and when a received pressure value is greater than a preset pressure value, a system sends out an alarm, and the press machine stops press fitting. According to the press fitting device, in the process of pressing a sleeve-type component, the component is determined to be off-centered or not when being pressed by comparing pressure of the component, when a pressure value is greater than a theoretical value, the component stops being pressed, and the pressed position of the sleeve-type component is realigned, so that a situation that the sleeve-type component is perpendicular to a shaft-type component in the process of pressing is ensured, and therefore, the sleeve-type component is not damaged, and the contact stress of the component after being pressed is uniform.
Description
Technical field
The utility model relates to a kind of interference assembling press-loading apparatus.
Background technology
When the current cover parts for interference fit and axial workpiece cold-pressing assembly, the general forcing press that adopts press-fits, during assembling, the pressure of forcing press acts on technique pressing plate by main shaft, and the effect by pressing plate is pressed into cover parts the corresponding position of axial workpiece of fixed placement.This press mode, when determining maximum pressure, often according to the elastic modelling quantity of material, maximum interference amount, bearing inner race diameter and axle external diameter, and length of fit calculates, and the maximum pressure of selecting often press-fits.In assembling process, as to run into axial workpiece be that little value, cover parts are during for large value, while being minimum interference amount, in process cover parts being pressed into maximum pressure, can deposit and press inclined to one side phenomenon, as do not found in time, light cause being pressed into that the contact stress of rear cover parts and axial workpiece is inhomogeneous, out of plumb, when serious, even cause cover parts directly to be damaged by pressure.
Utility model content
In order to overcome above defect, the interference assembling press-loading apparatus that provides a kind of pressure to monitor is provided the purpose of this utility model.
The technical solution of the utility model is, a kind of interference assembling press-loading apparatus, it comprises forcing press, axial workpiece, cover parts, also comprise computer control device, pressure sensor, position sensor, Joining clasp, described pressure sensor is located at the main shaft bottom of forcing press, pressure sensor inputs to computer control device by the pressure signal detecting, Joining clasp is contained on main shaft, position sensor detects the displacement of main shaft by Joining clasp, and the displacement signal detecting is inputed to computer control device, computer control device pre-enters cover parts with respect to the displacement of axial workpiece and the theoretical change curve between pressure, computer control device is compared the theoretical change curve between the force value receiving and shift value and the displacement setting in advance and pressure, when surpassing the force value setting in advance, system alarm, forcing press stops press-fiting.
Described cover parts is to be vertically pressed in axial workpiece.
Technique effect of the present utility model is: due to cover parts is inputed to computer control device inside in advance in advance with respect to displacement and the theoretical change curve between pressure of axial workpiece, at cover parts, be pressed in process, by its pressure relatively, whether eccentricly judge while being pressed into, when force value is greater than theoretical value, stop being pressed into, again the position that centering cover parts is pressed into, thereby, guaranteed that in process of press in, cover parts is vertical with axial workpiece, thereby can not damage cover parts, and it is even to be pressed into rear contact stress.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
With reference to accompanying drawing, a kind of interference assembling press-loading apparatus, it comprises principal axis of pressing machine 1, axial workpiece 7, cover parts 6, technique pressing plate 5, fixed head 8, computer control device 9, pressure sensor 4, position sensor 3, Joining clasp 2 for axle.Described pressure sensor 4 is located at principal axis of pressing machine 1 bottom, and pressure sensor 4 inputs to computer control device 9 by the pressure signal detecting.Described technique pressing plate 5 is placed in cover parts 6 tops.Joining clasp 2 is contained on principal axis of pressing machine 1, position sensor 3 is by the stroke of Joining clasp 2 detected pressures owner axles 1, and the displacement signal detecting is inputed to computer control device 9, computer control device 9 pre-enters displacement by going out according to finite element analysis computation and the theoretical change curve between pressure, then the force value receiving and shift value and this theory change curve are compared, when surpassing the force value setting in advance, system alarm, forcing press stops press-fiting.
By axle, use fixed head 8 fixed vertical to be placed on forcing press axial workpiece 7, utilize chamfering and the gravity self-centering of cover parts 6 to aim at axial workpiece 7, technique pressing plate 5 is placed on cover parts 6 upper ends, and manual adjustments Joining clasp 2 contacts with position sensor 3.The input in contact detection loop in computer control device 9, output line are connected on respectively to pressure sensor 4 lower ends and axial workpiece 7 surfaces.While press-fiting, crawl regulates principal axis of pressing machine 1, and pressure sensor 4 lower ends are contacted with technique pressing plate 5.The moment of contact, detect loop and judge that rapidly this position is as program coordinate zero position, and the starting point signal pressurizeing as forcing press, in press-fiting process, the automatic Real-time Collection of computer control device 9, preserve pressure sensor 4 and the position sensor 3 moment instantaneous value of each position, then the force value receiving and shift value and this theory change curve are compared, when surpassing the force value setting in advance, system alarm, forcing press stops press-fiting, and centering press-fits position again.
Due to cover parts 6 is inputed to computer control device 9 inside in advance in advance with respect to displacement and the theoretical change curve between pressure of axial workpiece 7, at cover parts 6, be pressed in process, by its pressure relatively, whether eccentricly judge while being pressed into, when force value is greater than theoretical value, stop being pressed into the position that centering cover parts 6 is pressed into again, thereby, guaranteed that in process of press in, cover parts 6 is vertical with axial workpiece 7, thereby can not damage cover parts 6, and it is even to be pressed into rear contact stress.
Be more than a kind of embodiment of the present utility model, a preferred demonstration example.The scope that the utility model application is asked for protection has more than and is limited to described embodiment.All and technical scheme the present embodiment equivalence all belongs to protection domain of the present utility model.
