Abstract
The utility model discloses a special locating clamping fixture for processing a wind power bearing retainer. The main structure of the special locating clamping fixture for processing wind power bearing retainer comprises a circular reference plane. A clamping fixture frame is vertically arranged on the reference plane; round holes corresponding to a retainer are arranged in the clamping fixture frame; and the number of the holes is completely consistent with the number of the holes in the retainer; a plurality of screwed holes are uniformly and symmetrically arranged in the reference plane; the lower part of a prolonged stud is screwed into the screwed holes in the reference plane; a pressure pad at the upper part of the prolonged stud is pressed on the upper end surface of the retainer; the lower part of the other end of the pressure pad is supported by cylinder sizing blocks with equal height; and a hexnut is screwed on the top part of the prolonged stud to fix the pressure pad. The special locating clamping fixture is convenient to clamp and locate the retainer and can better guarantee the stability and safety during the processing.
Description
Technical field
The utility model relates to wind-power electricity generation machine bearing manufacture field, refers more particularly to the mechanical processing and positioning mold of wind power bearing retainer.
Background technology
Along with the continuous quickening of China's capital construction step, quickened construction to the wind-power electricity generation aspect.In order better to develop and develop the wind-powered electricity generation product, country has provided a lot of favourable policies, and purpose is to encourage enterprise to draw close to the wind-powered electricity generation industry, produces the environmental protection and energy saving product, revitalizes and when developing national industry, further develops novel industry.Country encourages the dynamics of new energy development constantly to strengthen, and causes various energy products to emerge in an endless stream.Wherein, rolling bearing is to be used for the important drive disk assembly of wind power plant, and it is according to the real-world operation situation of equipment and the service life of equipment, in conjunction with the rotation life-span of itself, confirms the size of its size and specification.Generally speaking, bearing diameter all 2-4 rice or more than.Bearing is made up of four parts, and basic structure is: outer ring, inner ring, retainer, rolling element.Wherein, inner ring and outer ring are the assembling matching part, and connect both retainers just, and it is after in each hole, putting into corresponding rolling element, reaches the purpose of Internal and external cycle rotation through freely rotating of rolling element.For example the planform of a kind of retainer commonly used is as shown in Figure 1, and external diameter basic size is φ 2413mm, highly is 81mm.Work in-process is considered from the angle of positioning and clamping, as if direct clamping on the platen face, because the wall thickness of retainer approaches (8mm), if each clamping position unbalance stress can produce serious stress deformation.Therefore, before machined, must earlier use the dial gauge centering, check the cylindrical situation of beating, judge whether and to process.So, need repeatedly centering, reduced production efficiency, and be not suitable for quantizing to produce.
Summary of the invention
For solving in the present above-mentioned retainer process, each clamping position unbalance stress, and problem such as centering efficient is lower, the utility model designs a kind of wind power bearing retainer and processes special-purpose positioning clamping fixture.Use the retainer after this mold is accomplished processing, its precision size and form and position tolerance can both satisfy drawing requirement, make the clamping centering become simply, and the stability of system keeps good in the process.
The concrete technical scheme of the utility model is achieved in that
Primary structure comprises circular datum plane, the mold frame vertically is set on datum plane; Have on the mold frame and the corresponding circular hole of retainer; And the quantity of the quantity in hole and retainer mesopore is in full accord, and several screwed holes symmetrically are set on datum plane; Add man-hour, put on numerical control borer special-purpose positioning clamping fixture main body side, and retainer is placed on the datum plane of special-purpose positioning clamping fixture main body, and the interior circle of retainer matches with the mold frame cylindrical of special-purpose positioning clamping fixture main body, cooperates to be matched in clearance; Lengthening stud bottom is screwed in the screwed hole on the datum plane, and the pressing plate on lengthening stud top is pressed in the retainer upper surface, and pressing plate other end bottom such as uses to support at high cylinder parallels, the lengthening stud top hex nut fixation clip of screwing on.
The utility model can make retainer integral body be in level and vertical optimum position through the auxiliary elements such as lengthening stud on the adjustment positioning clamping fixture, is convenient to centering, convenient processing, and also this utility model is installed, dismounting is also very convenient.
The beneficial effect of the utility model is: this mold makes things convenient for clamping, the location of retainer, and can better guarantee stability and security in the process.

Among the figure: 1. pressing plate, 2. hex nut, 3. lengthening stud, 4. retainer, 5. special-purpose positioning clamping fixture main body 6. waits high cylinder parallels.
The specific embodiment
Just with combining accompanying drawing and embodiment to specify the utility model.
The primary structure of the utility model comprises circular datum plane, the mold frame vertically is set on datum plane; Have on the mold frame and the corresponding circular hole of retainer; And the quantity of the quantity in hole and retainer mesopore is in full accord, and several screwed holes symmetrically are set on datum plane; Add man-hour, special-purpose positioning clamping fixture main body 5 sides put on numerical control borer, and retainer 4 is placed on the datum plane of special-purpose positioning clamping fixture main body 5, and the interior circle of retainer 4 matches with the mold frame cylindrical of special-purpose positioning clamping fixture main body 5, cooperates to be matched in clearance; Lengthening stud 3 bottoms are screwed in the screwed hole on the datum plane; The pressing plate 1 on lengthening stud 3 tops is pressed in retainer 4 upper surfaces; Pressing plate 1 other end bottom such as uses to support at high cylinder parallels 6, lengthening stud 3 tops hex nut 2 fixation clips 1 of screwing on.
The numerical control borer model of present embodiment is TK6513, and the quantity of screwed hole is 12, and the Kong Shiyong dial gauge that adds the retainer in man-hour is pressed the big cylindrical centering of retainer 4; Guarantee the tolerance that circle is beated and allowed, programming, tool setting; Coordinate points is set, bores reaming, thick, right boring hole.Its method is suitable for, and process is stable, and operating personnel can reach the stage of skilled operation.
The utility model is not limited to the foregoing description, and any equivalent concepts in the technical scope that the utility model discloses perhaps changes, and all classifies the protection domain of the utility model as.
