Abstract
The utility model discloses a special fixture for processing thicknesses of thrust bearing bushes of a fan, which is characterized in that an iron plate is fixedly provided with a screw; a trim strip is arranged on the iron plate by the screw and a nut; a cushion block is pressed on the lower side of one end of the trim strip; and the thrust bearing bushes are pressed on the lower side of the other end of the trim strip. According to the fixture, one-step clamping and simultaneous processing of one set of thrust bearing bushes (6 to 10 blocks of thrust bearing bushes) can be implemented; moreover, the thickness deviation is controlled in the range of plus and minus 0.01mm; working efficiency can be greatly improved; and processing time is shortened.
Description
Technical field
The utility model relates to the machining servicing unit, particularly a kind of blower fan thrust bearing shoe thickness Special Fixture for Machining.
Background technology
Usually can run into the wearing and tearing of blower fan thrust bearing shoe when maintenance of fan, this moment, the blower fan thrust bearing shoe need be changed.In order to guarantee the assemblage gap between thrust bearing shoe and thrust disc, before installing, new blower fan thrust bearing shoe to carry out thickness processing.The blower fan thrust bearing shoe spare part of producer generally leaves thickness allowance.One secondary thrust bearing shoe has 6～10, and 0.05mm～0.15mm is removed in every thickness reconditioning, and thickness deviation requires in positive and negative 0.01mm scope.Because the thrust bearing shoe working face has one deck babbit, working face is placed with carries out the back side add man-hour on grinding machine, electromagnetic force is inhaled incessantly, usually processes on CNC milling machine.In the milling machine process, the processing of one one, processing, Measuring Time is long, and particularly in order to guarantee precision, the thickness measure time is consuming time a lot.
The utility model content
Technical problem to be solved in the utility model is, by making a Special clamp for grinder, realizes thrust bearing shoe batch machining on grinding machine, satisfies the thickness requirement on machining accuracy of thrust bearing shoe, shortens process time simultaneously, increases work efficiency.
The utility model is realized above-mentioned purpose by the following technical solutions, and a kind of blower fan thrust bearing shoe thickness Special Fixture for Machining is characterized in that, iron plate is fixed with screw rod, press strip is installed on iron plate by screw rod and nut, is pressed with cushion block below press strip one end, is pressed with thrust bearing shoe below the other end.
The utility model has the advantages that, this fixture can realize that a secondary thrust bearing shoe (6～10) once clamps, and processing, and thickness deviation simultaneously all is controlled in positive and negative 0.01mm scope, can greatly increase work efficiency, and shortens process time.
Description of drawings
Fig. 1 is perspective view of the present utility model.
In figure: 1-grinding machine platform, 2-thrust bearing shoe, 3-press strip, 4-nut, 5-screw rod, 6-cushion block, 7-iron plate.
The specific embodiment
Now in conjunction with the accompanying drawings and embodiments, the utility model is described in further detail, referring to Fig. 1, a kind of blower fan thrust bearing shoe thickness Special Fixture for Machining, it is characterized in that, iron plate 7 is fixed with screw rod 5, and press strip 3 is installed on iron plate 7 by screw rod 5 and nut 4, be pressed with cushion block 6 below press strip 3 one ends, be pressed with thrust bearing shoe 2 below the other end.
Embodiment:Be adsorbed on grinding machine platform 1 with a large rectangle iron plate 7, be welded with screw rod 5 on rectangle iron plate 7, and thrust bearing shoe 2 working faces are placed with on grinding machine platform 1, the back side up, pass screw rod 5 with press strip 3, the two ends of press strip 3 are pressed in respectively on thrust bearing shoe 2 sector bottoms and cushion block 6, with nut 4 lockings.Such one 6～10 of secondary thrust bearing shoe 2(one pairs, Fig. 1 only illustrates 2, all the other are identical) just can process disposable completing simultaneously on grinding machine.Because grinding machine self precision is high, be easy to control every thrust bearing shoe 2 thickness machining accuracies and be controlled in positive and negative 0.01mm scope, avoid every to measure comparison, increase work efficiency.
