The technological scheme that the utility model realizes the employing of its object is as follows.
A kind of bearing positioning device, comprises threaded stem, nut, pushing tow bearing, support, gasket ring and positioning rod that equal concentric is arranged; Described threaded stem is each passed through nut, pushing tow bearing, support, gasket ring and positioning rod; Described support and gasket ring are set up in bearing both sides and conflict bearing respectively; Described nut is threaded with threaded stem, and nut side conflict pushing tow bearing; Described support comprises cylinder and plectane; Described cylinder is the cylindrical body of hollow; Described plectane is circular flat board, and plectane is fixedly connected with cylinder at circumference place; Described pushing tow bearing is embedded at the center of plectane; Described gasket ring is the rigid annulus of hollow; Described positioning rod is threaded with threaded stem, and positioning rod side contacts mutually with gasket ring.
Described cylinder offers observation groove; Described observation groove is strip, and is distributed in cylinder.
The cross section of positioning rod is positive six shapes.
The internal diameter of gasket ring is greater than the external diameter of threaded stem, and the external diameter of gasket ring is less than the external diameter of bearing.
The external diameter of threaded stem is less than the internal diameter of bearing; The internal diameter of cylinder is greater than the external diameter of bearing.
This positioning device structure is reliable, simple operation, adjusts the position of bearing on parts by rotating screw cap.Because the screw thread on screw rod is comparatively thin, the displacement of energy accurate adjustment bearing, thus improve the positioning precision of bearing.And the stressed pressure of bearing is reduced by arranging gasket ring, avoid bearing damage, ensure that the working environment of bearing, extend the working life of bearing.

Fig. 2 is sectional view of the present utility model;
In figure: 100-parts, 200-bearing, 201-axis hole, 310-threaded stem, 320-nut, 330-pushing tow bearing, 340-support, 341-cylinder, 341a-observe groove, 342-plectane, 350-gasket ring, 360-positioning rod.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, bearing 200 is installed on parts 100, and bearing 200 center is provided with axis hole 201.
A kind of bearing positioning device, comprises threaded stem 310, nut 320, pushing tow bearing 330, support 340, gasket ring 350 and positioning rod 360 that equal concentric is arranged.
Described threaded stem 310 is each passed through nut 320, pushing tow bearing 330, support 340, gasket ring 350 and positioning rod 360.Support 340 and gasket ring 350 are set up in bearing 200 both sides and conflict bearing 200 respectively.
Described nut 320 is threaded with threaded stem 310, and nut 320 side conflict pushing tow bearing 330.Rotating screw cap 320, thus drive threaded stem 310 axial action.
Described support 340 comprises cylinder 341 and plectane 342; Described cylinder 341 is the cylindrical body of hollow, and the internal diameter of cylinder 341 is greater than the external diameter of bearing 200.Described plectane 342 is circular flat board, and plectane 342 is fixedly connected with cylinder 341 at circumference place; Described pushing tow bearing 330 is embedded at the center of plectane 342.During due to work, support 340 is fixed, and nut 320 needs to rotate, and is therefore arranged between nut 320 and support 340 by pushing tow bearing 330, play reduce nut 320 when rotating support 340 to its resistance.
Described gasket ring 350 is the rigid annulus of hollow; The internal diameter of gasket ring 350 is greater than the external diameter of threaded stem 310, and the external diameter of gasket ring 350 is less than the external diameter of bearing 200.During work, gasket ring 350 is subject to the axial force of positioning rod 360, thus promotion bearing 200 moves axially to specified position.The setting of gasket ring 350, increased lifting surface area, reduces the pressure of positioning rod 360 pairs of bearings 200, and when avoiding locating, this device is to the damage of bearing 200.
Described positioning rod 360 is threaded with threaded stem 310, and positioning rod 360 side contacts mutually with gasket ring 350.The cross section of positioning rod 360 is positive six shapes, convenient wrench rotating position bar 360.The axial length of positioning rod 360 is at least the twice of threaded stem 310 diameter, thus less between cog is stressed.
Described cylinder 341 offers and observes groove 341a; Described observation groove 341a is strip, and is distributed in cylinder 341.Observe the setting of groove 341a, convenient when using this positioning device, observe the position of bearing 200 on parts 100.
The external diameter of threaded stem 310 is less than the internal diameter of bearing 200.Threaded stem 310 is all separated with gap with support 340, bearing 200, gasket ring 350, avoids threaded stem 310 to touch mutually with support 340, bearing 200, gasket ring 350.
During work, first bearing 200 is tentatively installed on parts 100.Then threaded stem 310 is passed bearing 200.Threaded stem 310 side wears nut 320, pushing tow bearing 330 and support 340, and opposite side wears gasket ring 350 and positioning rod 360.Then with tool into rotation nuts 320 such as spanners, threaded stem 310 drives positioning rod 360 axial action, and gasket ring 350 pushes bearing 200, makes bearing 200 move to specified position on parts 100, locates complete.
The utility model is illustrated according to embodiment, and under the prerequisite not departing from present principles, this device can also make some distortion and improvement.It should be pointed out that and all drop on the technological scheme that all employings are equal to replacement or the mode such as equivalent transformation and obtain in protection domain of the present utility model.
