Description

Friction welding machine device for screw-thread steel bar connector and related building materials

Technical Field

The utility model relates to the field of welding equipment, in particular to a friction welding machine device for a screw-thread steel bar connector and related building materials.

Background

The patent document of Chinese patent application No. CN201920709249.8, named "a friction welding machine capable of realizing no circular ring" discloses a technical scheme of a related friction welding machine. The technical scheme comprises the following technical characteristics: the clamping mechanism comprises a clamping mechanism support body, a first movable clamping block, a second movable clamping block, a screw pair, a coupler B, a clamping motor, a clamping welding piece A and a rotating welding piece B.

In order to enable the first movable clamping block and the second movable clamping block to accurately clamp the clamping weldment A, V-shaped clamping notches (see figure 5 of the specification drawing) which are oppositely arranged are respectively formed on the first movable clamping block and the second movable clamping block. Because the first movable clamping block and the second movable clamping block both adopt an integrated clamping block structure, the size of the V-shaped clamping notch is fixed and cannot be changed randomly according to the needs, so that the clamping range of the V-shaped clamping notch is limited and the welding parts with bigger and smaller sizes cannot be clamped. When a welding piece with a bigger or smaller clamping size is required to be clamped, the whole first movable clamping block and the second movable clamping block have to be replaced, and the first movable clamping block and the second movable clamping block with proper V-shaped clamping gaps are replaced, so that the requirement of accurate clamping can be met. Because the volumes of the first movable clamping block and the second movable clamping block are relatively large, the first movable clamping block and the second movable clamping block are inconvenient to assemble, disassemble and transfer, and therefore the convenience and the efficiency of replacement operation are low. And the first movable clamping block and the second movable clamping block of the large part occupy larger space, so that larger storage space is needed to store the unused first movable clamping block and second movable clamping block, and inconvenience is brought to enterprises in accessory management.

In the friction welding process, a large friction force is generated between the clamping weldment A and the rotating weldment B, so that a large clamping force is required to be generated on the clamping weldment A by the first movable clamping block and the second movable clamping block. The mouth wall of the V-shaped clamping notch is extremely easy to wear and deform in the use process, so that the accuracy of clamping and positioning of the clamping weldment A can be affected. Because the V-shaped clamping notch can not be independently adjusted, the purpose of accurately clamping the weldment A can be met only by replacing the first movable clamping block and the second movable clamping block, and therefore the use and maintenance cost of a user is quite high.

Therefore, there is a great need to design a friction welding device that solves the above-mentioned technical problems.

After the clamping block 3 is reduced, the clamping block 3 is detachably arranged on the reinforcing block 2, so that the clamping range can be conveniently adjusted by replacing the clamping block 3, and a large-size component is not required to be disassembled and transferred, thereby improving the convenience and efficiency of the clamping range adjusting operation. Accordingly, only the small-sized clip pieces 3 are replaced when the clamping range is adjusted, so that the enterprise only needs a small space to store the clip pieces 3 to be used, which contributes to the improvement of the convenience of the enterprise in accessory management. When the area of the clamping tool on the friction welding machine device is worn and deformed, only the clamping block 3 is replaced, and other components are not required to be replaced, so that the use and maintenance cost of a user can be greatly reduced.

The friction welder assembly also includes a rotating clamp mechanism (not shown, here a conventional rotating clamp mechanism is used) disposed laterally adjacent the clamping gap 10 and configured to reciprocate away from the clamping gap 10 (here a drive mechanism on the numerically controlled machine is used to drive the spindle to move to reciprocate). When the friction welding machine device is used for welding a screw-thread steel bar connector (the connector is a screw joint or a screw-thread cylinder, the screw joint and the screw-thread cylinder are respectively fixed on two screw-thread steel bars to be connected together, and then the screw joint and the screw-thread cylinder are screwed together, so that the two screw-thread steel bars can be connected together); as shown in fig. 5, the screw bar 100 is first clamped by the clamping gap 10 and the connector is clamped by the rotating clip mechanism; then the rotary clamping mechanism is started to drive the connector to rotate and enable the connector to move towards the screw reinforcement, when the connector contacts the screw reinforcement, a large amount of heat is generated due to friction, so that contact positions of the connector and the screw reinforcement are melted and fused together, and finally the connector can be stably positioned on the screw reinforcement after cooling, and therefore the purpose of friction welding can be achieved.

In order to realize the automatic transfer connector, the following two schemes can be adopted: first, a robot manipulator is provided beside the rotating card holder mechanism to complete automatic connector loading and unloading operations by the robot manipulator. Second, add: vibration dish, letter sorting mechanism, removal feed mechanism, the connector is outwards carried through the vibration dish one by one, letter sorting mechanism sets up on the output of vibration dish to through the connector that letter sorting mechanism letter sorting direction is makeed mistakes, remove feed mechanism and be used for connecing the connector of normal output on the vibration dish, and transfer the connector to rotatory clamping mechanism. Thus, the purpose of automatically transferring the connector can be satisfied.

For automatic transfer of the rebar, an upper transfer mechanism may be provided beside the clamping gap 10 to transfer the rebar into the clamping gap 10 and to disengage the rebar from the clamping gap 10 by the transfer mechanism.
