Centering positioning device

Technical Field

The utility model belongs to the technical field of retooling location, concretely relates to centering positioner.

Background

With the continuous development of scientific technology and the increasing product market demand, the production and transportation efficiency of enterprises play an important role in balancing the market supply and demand relationship, and the transport vehicle gradually becomes an important carrying tool in the enterprises at present. Because the production workshop often equipment butt joint website is more, and the space is limited for equipment operating space is limited, traditional transfer car needs the cooperation of driving and fork truck to hoist the mould and put on the transport vechicle. The transfer mode of the traveling crane and the forklift not only needs a large amount of special professionals to operate, but also has high labor cost, great safety risk and lower efficiency. The transport vehicle which is only used as a transfer carrier in a workshop cannot meet the requirements of workshop production. The novel transfer trolley needs to have the functions of multi-docking station high-precision repeated positioning, carrying, transportation and the like.

Most AGV transfer trolleys in the market are small in load and large in size, adopt a computer control system, are complex in structure, mostly adopt inlet components and self-designed components, and are high in price; the purpose of accurate positioning is achieved by identifying a specific signal carrier through a vision sensor, when the load is large and the speed is high, the butt joint position is prone to deviation due to inertia of AGV driving and braking deceleration delay, and repeated accurate positioning is difficult to achieve.

For most enterprises in transition upgrades, the cost of the AGV is high and is not suitable for the existing production mode. Compared with a full-automatic navigation running AGV trolley, the manual remote control trackless transfer trolley with all functions of lifting, multi-point accurate positioning, carrying, transporting and the like is more suitable for the current production mode of a workshop. Due to manual operation, the multipoint repeated accurate positioning is quickly realized, and the production efficiency is improved.

SUMMERY OF THE UTILITY MODEL

For solving the problem of the repeated high accuracy location of transport vechicle single-point under the manually operation state, the utility model aims at providing an easy operation, repeated location many times has the device of forcing the centering function.

In order to realize the technical purpose, the utility model discloses a technical scheme as follows:

the centering and positioning device comprises a butt joint end and a fixed end, wherein the butt joint end is installed on a transport vehicle, the fixed end is installed at the position of a butt joint point, the butt joint end comprises a mounting support and a fixed hook, the mounting support is connected with a pin shaft, the pin shaft is connected with a guide wheel, the fixed hook is provided with an arc groove, the butt joint end comprises a V-shaped block and a ground support, and the ground support is provided with a lock shaft.

Further, the guide wheel is cylindrical, the edges of two ends of the guide wheel are respectively provided with an inclined plane of 45 degrees, and the inclined plane of the opening of the V-shaped block is set to be 90 degrees.

Further limit, two 60-degree chamfers are arranged at two ends of the arc groove.

Further limit, be connected with oil-free bush between leading wheel and the round pin axle.

The utility model has the advantages that:

the utility model adopts the V-shaped block and the ground support to limit, the guide wheel and the fixed hook of the butt joint end are arranged on the transport vehicle, and the V-shaped block and the ground support of the fixed end are fixed after being matched with the guide wheel and the fixed hook; the reasonable over-positioning is utilized to improve the butt joint stability of the transport vehicle; the walking and rotation freedom degree of the transport vehicle in the Y direction and the rotation in the X direction are limited through the V-shaped block, the walking and rotation freedom degree of the transport vehicle in the Z direction is limited through the ground support, and the walking freedom degree of the transport vehicle in the X direction is limited through the V-shaped block and the ground support.

Detailed Description

In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.

As shown in fig. 1 and 2, the utility model discloses a centering positioner, including installing butt joint end on transport vechicle a and installing the stiff end in butt joint website b department, the butt joint end includes installing support 3 and fixed couple 6, and installing support 3 is connected with round pin axle 2, and round pin axle 2 is connected with leading wheel 4, and fixed couple 6 is equipped with circular arc groove 61, and the butt joint end includes V type piece 7 and ground support 8, and ground support 8 is equipped with lock axle 81.

Wherein the guide wheel 4 is cylindrical, the edges of two ends of the guide wheel are respectively provided with an inclined plane of 45 degrees, and the inclined plane of the opening of the V-shaped block 7 is set to be 90 degrees. The two inclined surfaces play a role in guiding and forced centering in the butt joint process.

Further, two 60-degree chamfers are arranged at two ends of the arc groove 61. The chamfer can be used for butt joint guiding.

Wherein, be connected with oilless bush 1 between leading wheel 4 and round pin axle 2. Can reduce the friction force between the guide wheel 4 and the pin shaft 2 in the movement process

Wherein, the whole guide wheel 4 is treated by ion nitriding to increase the surface hardness and the wear resistance.

As shown in fig. 3, a mounting bracket 3 and a fixed hook 6 are mounted on a transport vehicle a, a V-shaped block 7 and a ground support 8 are mounted on a docking station b, the transport vehicle a is driven to the docking station through manual and manual remote control for first docking, and the reference of a centering and positioning device needs to be manually adjusted by an installer for the first docking; after the centering and positioning device is installed, manually operating the transport vehicle a to the docking station b, wherein the transport vehicle a is in a rising state at the moment, finely adjusting the state of the transport vehicle a under the guiding action of the two V-shaped blocks 7, when the guide wheels 4 are observed to be in complete contact with the V-shaped blocks 7, the transport vehicle a is forced to center, the transport vehicle a is operated to descend at the moment, when the fixed hook 6 completely falls on the lock shaft 81 on the ground support 8, the centering and positioning operation of the transport vehicle a is completed, and the centering and positioning accuracy can reach within 0.5 mm; when the butt joint needs to be removed, the transport vehicle a can be operated to walk only by lifting the transport vehicle a and separating the fixed hook 6 from the lock shaft 81 on the ground support 8. The whole butt joint process only needs to observe and adjust the position relation between the guide wheel 4 and the V-shaped block 7, the operation is simple and convenient, the time of the whole centering and positioning process does not exceed 2 minutes, only one operator is needed, the working efficiency is greatly improved, and the personnel cost is greatly reduced.
