Background technology:
When will carry out the pressing action for the electronic product machining part, need a kind of assembly that presses down, utilize motor-driven, pressure head component moves down, and determines to move down accurately distance by photoelectric sensor, by the guiding of guide rod, makes pressure head arrival standard operation position.Move by pressing like this, can increase work efficiency.
The utility model content:
The purpose of this utility model is to provide a kind of assembly that presses down, and is mainly used in miniature parts and adds the assembly that presses down process man-hour, and its motion is flexible, efficient is high, and the pressing position is accurate, and crudy is improved.
Technology solution of the present utility model is as follows:
A kind of assembly that presses down, it comprises motor, top board, bearing installing plate, reinforcement, inductor mounting blocks, photoelectric sensor, ball-screw, shaft coupling, screw mandrel bearing, column, base plate and pressure head component, described motor is installed on above top board; Described bearing installing plate is installed on below motor, and is reinforced by reinforcement; Described inductor mounting blocks is installed on the rear side of reinforcement; Described photoelectric sensor vertically is arranged on the inductor mounting blocks; Described ball-screw is installed on below motor by shaft coupling, and is installed on the bearing installing plate by the screw mandrel bearing; Described pressure head component is installed on the top board lower end by ball-screw; Described column has four, and the upper end is individually fixed in the below at four angles of top board, and the lower end is fixed on base plate;
Described pressure head component comprises sensing chip, pressure head component connecting plate, connecting rod, pressure head installing plate, guide rod, bearing, shaft bearing plate, contour screw and pressure head, and described sensing chip is installed on the pressure head component connecting plate; Described pressure head component connecting plate is connected and connects by guide rod with the pressure head installing plate by connecting rod; Described guide rod upper end is installed on top board, and the lower end is installed on shaft bearing plate, and guide rod by bearing on shaft bearing plate; Described pressure head is installed on the bottom of pressure head installing plate by contour screw.
In technique scheme, the guide rod in described pressure head component has four, and the both sides between connecting rod and pressure head installing plate respectively have two.
The beneficial effects of the utility model are:
The utility model is under the driving of motor, pressure head component moves down, and when pressure head component moves down, shaft bearing plate and connecting rod play the guiding role, assurance moves down the path and is not offset, and determines to move down accurately distance in folding process and by photoelectric sensor, and the guiding by guide rod, pressure head is remained on same plane, and pressure head arrive the standard operation position.The utility model is mainly used in miniature parts and adds the assembly that presses down process man-hour, and its motion is flexible, efficient is high, and the pressing position is accurate, and crudy is improved.
