Abstract
Provided is a connecting device of a bulb lead screw and a worm gear. A lower ball bowl is installed at the bottom of a turbine box, a worm is installed at the position of the upper middle portion of the turbine box, a turbine is installed in a cavity of the turbine box, the turbine is correctly meshed with the worm, a locating pin is installed in a bulb blind hole of the bulb lead screw, simultaneously a joint ball is installed on the locating pin protruding out of a ball, the joint ball right faces to a notch on the turbine, the ball of the bulb lead screw penetrates through a middle hole of the turbine to be installed on a ball bowl portion of the lower ball bowl, an upper ball bowl penetrates through the upper portion of the bulb lead screw to be installed on the turbine box, a pressing and covering board is installed on the turbine box, simultaneously the pressing and covering board is fixed through a bolt, and finally a connecting rod is installed on the bulb lead screw.
Description
Technical field
The present invention relates to a kind of jockey, the jockey of particularly a kind of ball screw and worm gear.Belong to the press technologies field.
Background technology
At present, in some medium-and-large-sized, high-grade forcing press products, the shut height of slide block is regulated the method that all adopts motor-driven adjusting; Promptly adopt by motor-operated scroll bar, scroll bar drives turbine, and turbine drives ball screw and in the internal thread of connecting rod, rotates; Come the shut height of adjusting slider with this, wherein in above-mentioned mechanism connects, on bulb, bore one with the perpendicular hole of ball screw axis; And in the hole installing and locating pin; Edge at the turbine endoporus has breach, and the outstanding position of alignment pin is stuck in the breach, limits the purpose of rotating each other between ball screw and the turbine with this.
Above-mentioned described alignment pin is a cylindrical configuration, still, because forcing press is when work; Ball screw is ceaselessly swung, and alignment pin is not only stuck easily in breach, causes and regulates difficulty; Simultaneously, the corner angle of alignment pin are also gnawed with it the part material on the turbine of contact easily, and form broken nitre and fall between ball screw and the ball bowl; Thereby cause the wearing and tearing between the moving component, reduce the service life of part.
Summary of the invention
The objective of the invention is to: the jockey of a kind of ball screw and worm gear is provided, overcomes in the jockey of above-mentioned ball screw and turbine, alignment pin is stuck easily in breach, the defective of the adjusting difficulty that is caused thus; Simultaneously, also be in order to overcome in the existing mechanism, the corner angle of alignment pin are gnawed the material on the turbine of contact with it easily, and the broken nitre that causes therefrom falls between bulb and the ball bowl, cause the defective of the heel and toe wear between the moving component.
For realizing above-mentioned purpose, the technical scheme that the present invention adopted is achieved in that the jockey of a kind of ball screw and worm gear, and it is the bottom that following ball bowl is installed to the turbine casing; Scroll bar is installed to the last medium position of turbine casing, in the cavity of turbine casing, turbine is installed, turbine and scroll bar correct engagement; Alignment pin is installed in the bulb blind hole of ball screw, on the alignment pin in protrusion bulb, installs the joint spheroid simultaneously, the joint spheroid is aligned the breach on the turbine; The ball bowl portion that is installed in down the ball bowl is passed in the ball screw bulb from the interstitial hole of turbine, last ball bowl is passed from the top of ball screw, and be installed in the turbine casing above; Cover clamp is installed in above the turbine casing; Be fixed with bolt simultaneously, last, with connecting rod be installed to ball screw above.
Beneficial effect: because spheroid has the universal free degree in breach, so, be not easy stuck; Simultaneously can not cause the phenomenon that bites to the piece surface that it contacted yet; Thereby also just avoid metal fragment to have prolonged mechanical service life to the heel and toe wear phenomenon that moving component caused, it is stuck easily to have overcome alignment pin; Cause defective and the alignment pin corner angle of regulating difficulty to gnaw easily, the broken nitre of part falls into the defective of wearing and tearing each other between ball screw and the ball bowl.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further.
Accompanying drawing 1 is a schematic diagram of the present invention.
Accompanying drawing 2 is A-A partial sections of accompanying drawing 1.
Shown in the figure: 1, ball screw; 2, turbine; 3, alignment pin; 4, joint spheroid; 5, scroll bar; 6, following ball bowl; 7, connecting rod; 8, go up the ball bowl; 9, turbine casing; 10, cover clamp; 11, bolt.
The specific embodiment
Following ball bowl 6 is installed to the bottom of turbine casing 9, scroll bar 5 is installed to the last medium position of turbine casing 9, installation turbine 2 in the cavity of turbine casing 9; Turbine 2 and scroll bar 5 correct engagement are installed to alignment pin 3 in the bulb blind hole of ball screw 1, on the alignment pin 3 in protrusion bulb, install joint spheroid 4 simultaneously; Joint spheroid 4 is aligned the breach on the turbine 2; The ball bowl portion that is installed in down ball bowl 6 is passed in ball screw 1 bulb from the interstitial hole of turbine 2, last ball bowl 8 is passed from the top of ball screw 1, and be installed in turbine casing 9 above; Cover clamp 10 is installed in above the turbine casing 9; Be fixed with bolt 11 simultaneously, last, with connecting rod 7 be installed to ball screw 1 above.
