Abstract
The utility model provides a welding manipulator which comprises a base, a stand column arranged on the base, a lifting base, a drive motor arranged at the top of the stand column, a screw rod, a screw rod nut base, a screw rod nut, a limiting block and a safety nut. One end of the screw rod is connected with the drive motor; the other end of the screw rod is fixed to the stand column. The screw rod nut base is fixed to the lifting base. The screw rod nut is fixed to the screw rod nut base. The screw rod and the screw rod nut are in matched transmission to enable the lifting base to lift perpendicularly along the stand column. The limiting block is fixed to the stand column and arranged below the screw rod nut. The screw rod penetrates through the limiting block. The safety nut is fixed to the screw rod and arranged below the screw rod nut. The welding manipulator is simple in structure and low in cost; due to the arrangement of the limiting block and the safety nut which are matched mutually, the falling lifting base can be protected; meanwhile, the using and maintenance cost is low, and only the screw rod nut needs to be replaced.
Description
Technical field
The utility model belongs to welding auxiliary equipment field, particularly a kind of manipulator.
Background technology
Manipulator is widely used in the manufacture of the cylindrical tubes such as pipeline, pressure vessel, boiler.Manipulator generally includes the parts such as base, column, elevating bracket, transmission device, fall-preventing protection device, and the transmission equipment comprises chain drive and two kinds of modes of screw rod transmission.The chain easy fracture of the manipulator of chain drive, cause elevating bracket to fall, and causes device damage, even affects production safety; Although the manipulator of screw rod transmission is slightly long service life, yet, after feed screw nut's wearing and tearing, the accident that still can cause elevating bracket to fall.Therefore, all fall-preventing protection device must be installed on manipulator.The manipulator of existing screw rod transmission adopts jam nut and limit switch jointly as fall-preventing protection device usually, in order to monitor the wear extent of feed screw nut.Yet, for the small operation machine, installing the structure relative complex that limit switch causes its fall-preventing protection device additional, cost is relatively higher.
The utility model content
The utility model purpose: the purpose of this utility model is to provide a kind of manipulator simple in structure, with low cost.
Technical scheme: a kind of manipulator that the utility model provides comprises base, is located at column, the elevating bracket on base, the drive motors of being located at the column top, screw mandrel, feed screw nut's seat, feed screw nut, limited block, jam nut; Described screw mandrel one end is connected with drive motors, and the other end is fixed on column; Described feed screw nut's seat is fixed on elevating bracket, and described feed screw nut is fixed on feed screw nut's seat; Described screw mandrel and feed screw nut coordinate transmission, make the elevating bracket can be along the column vertical lift; Described limited block is fixed on column and is located at the feed screw nut below; Described jam nut is fixed on screw mandrel and is located at the feed screw nut below; Described screw mandrel is through limited block and jam nut.
As preferably, described jam nut is located at 10-15mm place, feed screw nut below.
Preferred as another kind, described feed screw nut and jam nut are oppositely arranged.
Beneficial effect: the manipulator that the utility model provides is simple in structure, with low cost, the limited block of working in coordination by setting and jam nut, thus can protect the elevating bracket of tenesmus; Simultaneously, the use and maintenance cost is low, only needs to change the feed screw nut and gets final product.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model manipulator.
The local enlarged side view that Fig. 2 is the utility model manipulator.
Fig. 3 is the local enlarged front view of the utility model manipulator.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model manipulator is further illustrated.
Manipulator, be shown in Fig. 1 to Fig. 3, comprises base 1, is located at column 2, the elevating bracket 3 on base 1, the drive motors 4 of being located at column 2 tops, screw mandrel 5, feed screw nut's seat 6, feed screw nut 7, limited block 8, jam nut 9; Screw mandrel 5 one ends are connected with drive motors 4, and the other end is fixed on column 2; Feed screw nut's seat 6 is fixed on elevating bracket 3, and feed screw nut 7 is fixed on feed screw nut's seat 6; Screw mandrel 5 and feed screw nut 7 coordinates transmissions, makes the elevating bracket 3 can be along column 2 vertical lifts; Limited block 8 is fixed on column 2 and is located at feed screw nut 7 belows, and screw mandrel 5 is through limited block 8; Jam nut 9 is fixed on screw mandrel 5 and is located at feed screw nut 7 10-15mm places, below; Described feed screw nut and jam nut are oppositely arranged.
When this manipulator uses, drive motors 4 coordinates transmissions by screw mandrel 5 and feed screw nut 7, makes the elevating bracket 3 can be along column 2 vertical lifts; Jam nut 9 is along with feed screw nut's synchronization lifting; After feed screw nut 7 wearing and tearing cause elevating bracket 3 to fall, elevating bracket 3 drives feed screw nuts 7, jam nut 9 drops jointly, and jam nut 9 drops down onto on limited block 8 limited 8 to be stopped, thereby has avoided the tenesmus of elevating bracket 3.
