Abstract

The invention discloses a rotation screw rod synchronous movement device, which comprises a left base and a right base, wherein the left base is fixedly provided with a servo motor and a screw rod mounting seat; the screw rod mounting seat is provided with a left screw rod in a hinged way; the left base is also fixedly provided with a linear guide rail which is matched with a left sliding block carrier of the left screw rod; the servo motor is fixedly connected with the left screw rod through a coupler; the right base is fixedly provided with a support; the support is provided with a right screw rod in a hinged way; the right base is also fixedly provided with a linear guide rail which is matched with a right sliding block carrier of the right screw rod; and the left screw rod is fixedly connected with the right screw rod through a connecting rod. The synchronous movement device in which the servo motor is used for driving a rotation screw rod can be synchronously moved in the positioning and clamping process and has high positioning accuracy after being moved.

Description

The rotating threaded shaft synchronous shifter
Technical field:
The present invention relates to be used for the pressing machine technology field of electronic product loam cake, lower cover pressing, relate to a kind of synchronous shifter that is used for the pressing machine in particular.
Background technology:
Electronic product (mobile phone, MP4 etc.) is in installation process, and lids such as its upper and lower cover need be put in the carrier of pressing machine, just can carry out pressing after positioning, clamping, and just need use synchronous location, clamping device this time; Existing synchronous location, clamping device generally are to adopt a plurality of cylinders side for upper and lower covers on all directions to carry out clamping and positioning, but the resistance that cylinder is subjected in running, many-sided influences such as pressure of air feed, be difficult to accomplish real same moved further, successively not with having contacted of upper and lower covers, and pressure is also different, so positioning accuracy is very poor, and adopts a plurality of cylinders location to clamp, the volume of whole device is very big, is unfavorable for installing.
Summary of the invention:
The purpose of this invention is to provide is at the deficiencies in the prior art part, and a kind of synchronous shifter that utilizes servomotor driven rotary leading screw is provided, and it can accomplish same moved further in the process that the location clamps, and moves back positioning accuracy height.
Technology solution of the present invention is as follows:
The rotating threaded shaft synchronous shifter, comprise left and right sides base, be fixed with servomotor and leading screw mount pad on the described left base, hinged on the described screw mandrel mount pad left leading screw is installed, also be fixed with the line slideway that the left slider carrier with left leading screw matches on the described left base, described servomotor is connected and fixed by shaft coupling and described left leading screw; Be fixed with a bearing on the described right base, hinged on this bearing right leading screw be installed; On right base, also be fixed with the line slideway that the right slide block carrier with right leading screw matches; Described left and right sides leading screw is fixedly connected by connecting rod.
Described synchronous shifter, described connecting rod is made of left and right sides link and intermediate bar, and described left and right sides link is fixedlyed connected with left and right sides leading screw respectively, and the diameter of described intermediate bar is less than the diameter of described left and right sides link.
Beneficial effect of the present invention is:
1, synchronous shifter of the present invention, utilize the direction of rotation difference of two left and right sides wire rod threads, thereby reach under the situation that a servo motor drives, slide block carrier on the two rhizoid bars is simultaneously along opposite direction translation, when servo motor just changes, carrier on the screw mandrel is drawn close to the center position translation simultaneously, when servo motor reverses, carrier on the screw mandrel simultaneously to the both sides translation separately, moving so just can realize being synchronized with the movement of two slide block carriers, one starting stops in the time of moving, stop together in the time of work, deviation can not occur, when workpiece is clamped, in the time of the location, two slide block carriers touch workpiece simultaneously, simultaneously workpiece are applied power, have guaranteed the accurate of workpiece location.
2, adopt servo motor as the power source that drives, locating accuracy is higher like this, and structure is simpler, easier operation and control.Because it is very accurate that servo motor drives the precision of leading screw, the position of controlling the slide unit carrier with the rotation of servo motor is just more accurate, easier control.
Description of drawings:
The present invention is described further below in conjunction with accompanying drawing:
Fig. 1 is the structural representation after two cover apparatus of the present invention are arranged vertically;
Fig. 2 is the plane after two cover apparatus of the present invention are arranged vertically.
The specific embodiment:
The following stated only is preferred embodiment of the present invention.
Embodiment sees accompanying drawing 1,2; Be the schematic diagram that two covers device of the present invention is combined into, it utilizes two these devices of cover, has well realized clamping, location to four faces of product, and certainly, apparatus of the present invention also can be used separately, realizes the location clamping for two faces of product.Rotating threaded shaft synchronous shifter of the present invention, comprise left and right sides base 9,10, left and right sides base is to be used for and the fixing usefulness of the lathe of pressing machine, be fixed with servomotor 1 and leading screw mount pad 12 on the described left base, hinged on the described screw mandrel mount pad 12 left leading screw 3 is installed, also be fixed with the line slideway 11 that the left slider carrier 2 with left leading screw 3 matches on the described left base 9, left slider carrier 2 is fixed on the guide rail slide block of line slideway, and described left slider carrier can move around on this line slideway; Described servomotor 1 is connected and fixed by shaft coupling 14 and described left leading screw 3; The impact that shaft coupling produces in the time of can the efficient buffer transmission and trembling, guarantee transmission smoothly, steadily, be fixed with a bearing 6 on the described right base 10, hinged on this bearing right leading screw 5 is installed; On right base 10, also be fixed with the line slideway 4 that the right slide block carrier 7 with right leading screw 5 matches; Right slide block carrier 7 is fixed on the guide rail slide block of line slideway,, described left and right sides leading screw is fixedly connected by connecting rod 13.Described connecting rod 13 is made of left and right sides link 13a, 13b and intermediate bar 13c, described left and right sides link is fixedlyed connected with left and right sides leading screw respectively, the diameter of described intermediate bar is less than the diameter of described left and right sides link, like this when two devices are used in combination, because intermediate bar intersects, so the littler layout that helps device of its diameter.
