Description

A kind of positioner

Technical field

This utility model relates to a kind of positioner, belongs to welding displacement equipment technical field.

Background technology

Raising along with the development of solder technology and automatization level; At welding technology field, traditional manual welding mode is progressively replaced by the mode of automatic welding. Existing automatic welding relies primarily on positioner and after Workpiece clamping, workpiece will be driven to rotate. Adjust the position while welding of workpiece with this, and then facilitate welding gun to complete the welding job of workpiece. Existing positioner, due to the restriction of reasons in structure, can only drive workpiece counterclockwise or to turn clockwise, adjust the position of workpiece circumferencial direction, the weld seam of circumferencial direction is welded. But for the weld seam of other angles of workpiece, the attitude that can only manually adjust welding gun goes to meet the welding requirements of workpiece. Work efficiency is low, and weldquality cannot ensure, it is impossible to meet the needs that enterprise produces. The problem that additionally existing positioner also has structure complexity, operating difficulties. It is therefore desirable to research and develop a simple in construction, easy to use; Multi-angle can adjust the location of workpiece, to solve the welding displacement device of inefficiency, poor welding quality and structure challenge that existing positioner exists, to meet the needs that enterprise produces.

Summary of the invention

The purpose of this utility model is in that: provide a kind of simple in construction, easy to use; Multi-angle can adjust the location of workpiece, to solve the positioner of inefficiency, poor welding quality and structure challenge that existing positioner exists.

The technical solution of the utility model is:

A kind of positioner, it is made up of base, rotating shaft, drive motor, adjustment worm gear, adjustment worm screw, rotating disk, assembling ring flat-plate, jaw and jaw driving dish; It is characterized in that: base is fixed with drive motor by rotating shaft; The outfan of drive motor is fixed with rotating disk; Rotating disk is fixed with assembling ring flat-plate; On assembling ring flat-plate by the rail groove that arranges radially movable multiple jaw is installed; Between jaw and rotating disk, activity is provided with jaw driving dish; The rotating shaft of jaw driving dish side is fixed with adjustment worm gear; Adjust and the base below worm gear is provided with adjustment worm screw; Adjust worm screw to be connected with adjustment worm gear engagement.

Described jaw is cross section is the elongate body of " 7 " font, and the lower surface interval shape of jaw is provided with multiple driving tooth.

Described jaw driving dish is torus; On the periphery of jaw driving dish, symmetry shape is provided with turning handle; The upper surface of jaw driving dish from inside to outside successively interval shape be provided with multiple annular driver slot; Described annular driver slot is corresponding with the driving tooth of jaw.

Described termination, adjustment worm screw one end is fixed with rotation handwheel.

The utility model has the advantage of:

This positioner, can adjust worm screw by rotation during use and drive adjustment worm gear to rotate around the axis; Adjusting worm gear will drive drive motor, rotating disk, assembling ring flat-plate and workpiece to rotate to suitable angle by rotating shaft in rotation process, and then facilitates the welding of workpiece special angle weld seam. Solve existing positioner when workpiece special angle weld seam welds, it is necessary to the problem manually adjusting inefficiency that posture of welding torch causes and poor welding quality. This positioner, simple in construction, easy to use; Multi-angle can adjust the location of workpiece, solve inefficiency, poor welding quality and baroque problem that existing positioner exists, be particularly suitable for the needs that enterprise uses.

Detailed description of the invention

This positioner, is made up of base 1, rotating shaft 2, drive motor 3, adjustment worm gear 4, adjustment worm screw 5, rotating disk 6, assembling ring flat-plate 7, jaw 8 and jaw driving dish 9: be fixed with drive motor 3 by rotating shaft 2 on base 1; The outfan of drive motor 3 is fixed with rotating disk 6; Rotating disk 6 for cross section in the disc of " convex " font; The upper surface of rotating disk 6 is fixed with assembling ring flat-plate 7; Assembling ring flat-plate 7 is provided with multiple jaw 8 by rail groove 10 activity that arranges radially. Jaw 8 is the elongate body that cross section is " 7 " font, when the long end face of jaw 8 and absorption surface, it is possible to increase the contact surface of jaw 8 and workpiece, thus strengthening clamping force. The lower surface interval shape of jaw 8 is provided with multiple driving tooth 11.

Between jaw 8 and rotating disk 6, activity is provided with jaw driving dish 9; Jaw driving dish 9 is torus; On the periphery of jaw driving dish 9, symmetry shape is provided with turning handle 12; The upper surface of jaw driving dish 9 from inside to outside successively interval shape be provided with multiple annular driver slot 13; Annular driver slot 13 is corresponding with the driving tooth 11 of jaw 8. When jaw driving dish 9 rotates forward, jaw driving dish 9 can pass through annular driver slot 13 and drive tooth 11 to promote jaw 8 to move to the center of rotating disk 6 along rail groove 10. When jaw driving dish 9 reverses, jaw driving dish 9 will promote jaw 8 to move along rail groove 10 to the outer ring of rotating disk 6.

The rotating shaft 2 of jaw driving dish 9 side is fixed with adjustment worm gear 4; Adjust and the base 1 below worm gear 4 is provided with adjustment worm screw 5; Adjust worm screw 5 to be connected with adjustment worm gear 4 engagement. The termination, one end adjusting worm screw 5 is fixed with rotation handwheel 14.

When this positioner uses, first need to be placed on by workpiece on rotating disk 6; Subsequently by turning handle 12 manual rotation's jaw driving dish 9;Jaw 8 will be driven to move along rail groove 10 to the center of rotating disk 6 when jaw driving dish 9 rotates forward; During when jaw 8 and absorption surface and by Workpiece clamping, stop operating jaw driving dish 9. (referring to accompanying drawing 1～4).

Above procedure can adjust worm screw 5 by rotation handwheel 14 manual rotation after completing; When adjusting worm screw 5 forward or reverse, adjustment worm gear 4 can be driven around the shaft 2 clockwise or counterclockwise. Adjust worm gear 4 and will pass through the angle that rotating shaft 2 drives drive motor 3, rotating disk 6, assembling ring flat-plate 7 and workpiece rotation extremely suitable in rotation process. When workpiece is in suitable angle, stop operating adjustment worm screw 5. Finally starting drive motor 3, drive motor 3 will pass through rotating disk 6, assemble ring flat-plate 7, jaw 8 drives workpiece to rotate together. Workpiece is in rotation process, and welding gun will complete the welding job of workpiece weld seam. After welding job completes, pivoted jaw driving dish 9 makes it reverse, and now jaw 8 will move along rail groove 10 to the outer ring of rotating disk 6, after jaw 8 leaves workpiece; Stop operating jaw driving dish 9. Now take off workpiece, just can enter next cycle of operation.

This positioner, simple in construction, easy to use; Multi-angle can adjust the location of workpiece, solve existing positioner when welding workpiece special angle weld seam, it is necessary to the problem manually adjusting inefficiency that posture of welding torch causes and poor welding quality, be particularly suitable for the needs that enterprise uses.
