Description
Technical field
The present invention relates to a kind of tire production equipment.Specifically, be the drum watt telescoping mechanism that is used for producing on the bench of motorcycle and cycle casing.
Background technology
At present, the drum watt telescoping mechanism that is used for producing motorcycle and cycle casing all is a traditional mechanism.This traditional mechanism comprises a main shaft, two fixed disks and some strip tiles and assembly drum watt.Two fixed disks all are fixed on the main shaft, and spacing is arranged between them, and the length of this spacing and strip tile is suitable.The excircle of two fixed disks is to being evenly equipped with radial hole, and all there is guide post each inboard, strip tile two ends.Said guide post is along the radial arrangement of strip tile, and their end is fixed on the medial surface at strip tile two ends, and the other end stretches on two fixed disks in the corresponding a pair of radial hole, and the two is and is slidingly matched.Between two fixed disks cylinder is arranged, the cylinder body of this cylinder is taper, and all there is centre bore at its two ends, and it is sealing shape, slip shape by this two centre bore and is enclosed within on the main shaft.Axial pore is arranged on the main shaft, and this axial pore is connected with inner chamber of cylinder block.Piston is arranged in the cylinder body, and piston is fixed on the interior main shaft of cylinder body.The same position of each strip tile inboard all has inner convex platform, and these inner convex platforms all have an inclined-plane, is between this inclined-plane and taper cylinder body to be slidingly matched.Also be connected with extension spring between the medial surface of strip tile.During work,, cylinder is slided along main shaft, thereby under the ramp effect of cylinder lateral surface and strip tile inboard, the strip tile radially outwards be upheld or contraction by the pressure of gas in the control cylinder.Because guide post one end stretches on two fixed disks in the corresponding a pair of radial hole, and the two is and is slidingly matched, and directly contacts between guide post and radial hole, and contact area is big, makes frictional resistance bigger.And frictional resistance one is big, and guide post and radial hole are just easy to wear.In case guide post and radial hole wearing and tearing will make the fit clearance of the two increase, even can't use.Therefore, adopt said structure, need often to change guide post or fixed disk, not only maintenance load is big, and can improve production cost.
Summary of the invention
The problem to be solved in the present invention provides a kind of drum tile telescoping mechanism of tyre building machine.Use this drum tile telescoping mechanism of tyre building machine, can reduce maintenance load, reduce production costs.
For addressing the above problem, take following technical scheme:
Drum tile telescoping mechanism of tyre building machine of the present invention comprises a main shaft, two fixed disks and some strip tiles and assembly drum watt.Two fixed disks all are fixed on the main shaft, and spacing is arranged between them, and this spacing is corresponding with the centre-to-centre spacing of strip tile.The excircle of fixed disk is to being evenly equipped with radial hole, and all there is guide post each inboard, strip tile two ends.Said guide post is along the radial arrangement of strip tile, and their end is fixed on the medial surface at strip tile two ends, and the other end stretches on two fixed disks in the corresponding radial hole and the two is and is slidingly matched.Between two fixed disks cylinder is arranged, the cylinder body of this cylinder is taper, and all there is centre bore at its two ends, and it is sealing shape, slip shape by this two centre bore and is enclosed within on the main shaft.Axial pore is arranged on the main shaft, and this axial pore is connected with inner chamber of cylinder block; Piston is arranged in the cylinder body, and piston is fixed on the interior main shaft of cylinder body.The same position of each strip tile inboard all has inner convex platform, and these inner convex platforms all have an inclined-plane, is between this inclined-plane and taper cylinder body to be slidingly matched.Also be connected with extension spring between the lateral surface of strip tile.Be characterized in the radial hole on the fixed disk ball bushing being arranged, guide post is slidingly matched by being between this linear ball bearing and radial hole.
Take such scheme, have the following advantages:
Owing to be provided with ball bushing in the radial hole of the present invention on its fixed disk, guide post directly and this ball bushing be and be slidingly matched.Guide post only contacts with steel ball on the ball bushing, and does not contact with radial hole, has not only avoided the generation of radial hole abrasion condition, and the friction area of guide post is less, not easy to wear yet.Therefore, adopt structure of the present invention, do not need often to change guide post or fixed disk, not only reduced maintenance load, and can reduce production costs.
