Description

A kind of welding rotation positioner

Technical field

The utility model belongs to welding processing technical field, and in particular to a kind of welding rotation positioner.

Background technique

Welding, also referred to as welding, Rong connects, and is a kind of jointing metal in a manner of heating, high temperature or high pressure or other heat The purpose of engagement, positioner are reached in the manufacturing process and technology of plastic material such as plastics, welding by following three approach It is special welding ancillary equipment, for dragging workpiece to be welded, it is made to wait for that welding line moves to ideal position and carries out welding operation Equipment, the welding suitable for turning round work conjugates, to obtain ideal Working position and speed of welding.

Currently, positioner is many kinds of, but generally existing the problem of structure is complicated, volume is excessive, higher cost, If angle fixation always can bring many inconvenience to operator when welding, use bracket by metalwork in the prior art It after fixation, is driven by motor gear and drives bracket rotation, but the speed and angle that rotate are inaccurate, rotation is also not flat enough Surely, stability is poor in rotary course, and cannot stop and start in any position again.

Utility model content

For the above problem above, the utility model provides that a kind of operation is convenient, and practical welding rotates positioner.

A kind of welding that in order to solve the above technical problems, the technical scheme adopted by the utility model is: rotates positioner, packet The turntable and workbench for including pedestal, being set on pedestal, the chassis interior are equipped with motor, and the turntable inside center is set Rack gear, the gear ring are fitted with a plurality of planetary gears and a sun gear, the output shaft of the motor and the sun Gear is fixedly connected, and the workbench is fixedly arranged on the turntable, and the workbench is equipped with a plurality of clamp systems, each The clamp system includes hold-down support, pressing member and pusher cylinder, and the hold-down support is welded on told workbench, institute Pressing member to be stated to be articulated on the hold-down support, the telescopic end of the pusher cylinder is flexibly connected with the pushing generator terminal portion, and Pusher cylinder is fixed on the hold-down support side.

Further, the motor is AC servo motor.

Further, the pedestal is made of high-strength steel sheet.

Further, the planetary gear quantity is three.

Compared with prior art, the utility model has the beneficial effects that due under on each clamp system of workbench Casting die is articulated on hold-down support, and the telescopic end of pusher cylinder is flexibly connected with pressing member rear end, passes through pusher cylinder Elongation realizes that pressing member front end pushes and by workpiece automatic clamping on clamp system, and without manually locking one by one, efficiency is more It is high；Set AC servo motor connects and drives the rotation of sun gear transmission planetary gear that gear ring is driven to turn again in the pedestal having again It moves to realize turntable and worktable rotary, drives planetary gear to reach slowing effect to be able to achieve by sun gear The rotation of workbench is more steady, positions more accurate.

Detailed description of the invention

Fig. 2 is the utility model schematic perspective view；

Fig. 3 is the schematic diagram of internal structure of the utility model turntable.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment, based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

According to Fig. 1-3, the utility model provides a kind of technical solution: a kind of welding rotation positioner, including pedestal 1, the turntable 2 and workbench 3 being set on pedestal, the pedestal 1 are made of high-strength steel sheet, are set inside the pedestal 1 There is AC servo motor 11,2 inside center of turntable is equipped with gear ring 21, and there are three planetary gears 22 for the adaptation of gear ring 21 With a sun gear 23, the output shaft of the AC servo motor 11 is fixedly connected with the sun gear 23, the work Platform 3 is fixedly arranged on the turntable 2, and the workbench 3 is equipped with a plurality of clamp systems 4, and each clamp system 4 is Including hold-down support 42, pressing member 41 and pusher cylinder 43, the hold-down support 42 is welded on told workbench 3, under described Casting die 41 is articulated on the hold-down support 42, and the telescopic end of the pusher cylinder 43 and the lower 41 end activity of press connect It connects, and pusher cylinder 43 is fixed on 42 side of hold-down support.

In use, the pressing member 41 on each clamp system 4 for passing through workbench 3 is articulated on hold-down support 42, then lead to It crosses cylinder 43 and pushes 41 end of pressing member, realize that 41 front end of pressing member pushes and secure the workpiece against on clamp system 4, to realize Automatically working is more efficient, drives 23 transmission planetary gear of sun gear finally by the AC servo motor 11 on pedestal 1 22 rotations drive gear ring 21 dynamic to realize that 2 workbench 3 of turntable rotates, because driving planet tooth 22 to take turns by sun gear 23 again Reach slowing effect to be able to achieve more stably rotation, more accurately position.

While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art, It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
