Description
Technical Field
The invention relates to a mould, in particular to a mould for installing a stop ring, which is suitable for the assembling and sleeving process of a cylindrical roller bearing and belongs to the technical field of process assembly.
Background
In the past, when installing a stop ring (spring ring) of a cylindrical roller bearing, the company only needs to install the stop ring (spring ring) manually without any clamping fixture, put the stop ring (spring ring) on the bearing, push against one end of an opening of the stop ring, use a wooden hammer to knock the stop ring, and pound the stop ring into the bearing. The method has the advantages of high labor intensity, large field knocking sound, frequent hand-hitting phenomenon, low efficiency, easy waste generation, incapability of meeting the development and field requirements of companies, and urgent need of designing a hand-mounted pressing stop ring (spring ring) mounting mould.
Disclosure of Invention
In view of the defects of the prior art, the invention researches the existing installation process and the stop ring, and invents a clamping fixture for installing the stop ring, which meets the requirement of manual operation.
In order to achieve the purpose, the invention adopts the technical scheme that: the clamping fixture for mounting the stop ring comprises an upper die and a lower die, wherein the upper die is provided with a spring fixing hole along the circumferential direction, the circumferential direction of the upper surface of the lower die corresponding to the position of the spring fixing hole of the upper die is also provided with a spring fixing hole, the upper die is connected with the lower die through a spring, and a workpiece is sleeved in the lower die;
furthermore, the positions of the spring fixing holes on the upper die and the lower die are mutually corresponding, the number of the spring fixing holes is set to be 3, and the included angle of the central extension line between every two adjacent spring fixing holes in the upper die or the lower die is 120 degrees;
the purpose of installing springs in the upper die and the lower die is to enable the pressed upper die to rebound to an original position to prepare for next processing;
the upper die comprises an upper plate part and a pressing part, the pressing part is annularly arranged on the lower surface of the upper plate part, and a limiting bulge is arranged at any circumferential edge of the pressing part; the bottom of the pressing part with the limiting bulge is provided with a pressing angle, and the bottom ends of the pressing parts except the position with the limiting bulge are plane end surfaces;
the lower die comprises an upper inner wall which is a vertical section, a lower inner wall which is a closed conical section, a gap is arranged between the vertical section and the conical section on one side of the lower die, the gap height is 4mm, and a stop ring is arranged at the gap; a limiting groove matched with the shape of the limiting bulge in the upper die is arranged on the inner wall of the lower die on one side of the direction of the gap, the pressing part with the limiting bulge in the upper die is inserted into the limiting groove, and the pressing parts at other positions except the position with the limiting bulge are inserted into the inner wall of the lower die;
the diameter of the outer wall of the pressing part provided with the pressing angle in the upper die is the same as the inner diameter of the installed bearing workpiece, so that the pressing angle is completely inserted into the inner hole of the bearing workpiece; the outer wall of the pressing part at the bottom end of the middle plane of the upper die is smaller than the inner wall of the mounted bearing workpiece, so that the stop ring is completely pressed into the inner hole of the bearing;
the working principle of the invention is as follows: the stop ring is reduced in inner hole diameter through the inclined plane taper structure by designing the tire membrane, and meanwhile, the brake ring is pressed into the inner hole of the bearing after the inner hole diameter is reduced through the design of one end pressing angle and the other end plane of the pressing part, so that the brake ring is smoothly installed in place.
When in use, the bearing is firstly arranged at the bearing mounting position of the lower die to be assembled, and the stop ring is sleeved from the upper part of the lower die and is placed at the gap position; connecting the upper die to the lower die through a spring, aligning a pressing part of the upper die in the lower die, and then pressing the upper die, wherein in the process, a limiting bulge of the upper die is matched with a limiting groove of the lower die, when a pressing angle of the pressing part reaches the upper end of the stop ring, the pressing angle presses the stop ring to enable two ends of an opening of the stop ring to be staggered in spatial position, so that the diameter of the stop ring is changed, and at the moment, the inner diameter of the stop ring is reduced and the stop ring descends through the inner wall of the conical surface section of the lower die; continuously pressing the upper die, and when the stop ring is pressed to pass through the bottom of the conical surface section and reach the inner hole of the bearing, the stop ring is bounced into the inner hole of the bearing, so that the stop ring is installed; after the upper die is installed, the pressed upper die is rebounded to the original position through the action of a spring to prepare for next processing.
The invention has the beneficial effects that: the traditional manual installation is changed, and a wooden hammer is used for knocking the stop ring to smash the metal stop ring into the bearing; the requirement of manual operation is met, and the installation rejection rate is zero; the clamping fixture is light and convenient to move, and all the defects of knocking and hammering the stop ring can be eliminated; the bearing assembling machine has the advantages of being convenient to operate, low in labor intensity, capable of guaranteeing good appearance quality of bearing assembling, effectively reducing production cost and improving production efficiency by more than 2 times.
