Description

Technical Field

[0001] The utility model relates to a clamping assembly of a transport vehicle connector. Background Art

[0002] A transport truck is a tool used for quick point-to-point transportation on a flat surface. It is small and flexible, suitable for almost any occasion, and therefore plays a very important role in the company's logistics system. It is also relatively simple to operate. The transport truck connector is a supporting component installed on the transport truck body to connect the push rod and the chassis.

[0003] The processing of connectors requires multiple steps, the most important of which are turning, drilling, grinding, etc. In order to effectively limit the connector to prevent it from shifting during processing, the connector must be fixed in a matching fixture before processing to complete the positioning.

[0004] Although the existing clamps for fixing the connecting heads are also automatically operated by cylinders, they are relatively complex in structure and large in size, because each pressure block is driven by an independent rotary lifting cylinder. In order to effectively fix the connecting head, at least three pressure blocks are generally used, so at least three rotary lifting cylinders are required; and, due to the limitation of the action mode of the rotary lifting cylinder, the rotary lifting cylinder can only be fixed on the periphery of the connecting head and higher than the connecting head, which not only takes up a large space, but also interferes with the processing equipment, making the processing more inconvenient; in addition, the existing clamps for fixing the connecting head lack a flipping function, so they cannot be used in multi-tool combination processing equipment. The connecting head can only be removed and re-fixed after flipping, which makes the operation more cumbersome, and thus leads to low processing efficiency, which needs further improvement.

The left and right sides of the lifting block 4 are movably inserted into the slots 51 on the two square lifting columns 5 on the same side, so that the lifting block 4 and the lower end of the square lifting column 5 have the function of relative horizontal sliding.

[0041] Working principle:

[0042] At the same time, the telescopic end of the traction cylinder 2 in each clamping unit is driven to extend outward, and then the two square lifting columns 5 are driven to move upward along the corresponding oblique hole 32 with the help of the lifting block 4. During this process, the distance between the upper ends of any two square lifting columns 5 gradually increases; then the bottom of the connector to be processed is placed in the positioning cavity 31 of the positioning block 3, and the two positioning columns 7 are respectively inserted into the structural holes at the bottom of the connector, and at the same time, each limiting column 8 is embedded in the corresponding groove on the outer wall of the bottom of the connector; then the telescopic end of the traction cylinder 2 in each clamping unit is driven to retract inward to drive the upper ends of each square lifting column 5 to move downward and approach each other in the same way, until the limiting notches 61 on each pressing block 6 are pressed against the corresponding side edges of the top of the connector, thus completing the positioning and fixation of the connector, and then the processing equipment above the connector can be controlled to process the top of the connector.

[0043] If it is necessary to use the processing equipment located below the connector, first simultaneously drive the telescopic ends of the stop cylinders 11 in the two stop units to retract inward to drive the two stop pins 12 to move backward, so that the front ends of the two stop pins 12 leave the two stop holes 131 in the turntable 13, and then the rotating end of the rotating cylinder 9 can be driven to rotate 180 degrees, and then with the help of the turntable 13 and the support block 14, the bottom block 1, the positioning block 3 and the clamping unit are driven to rotate the same angle, so that the connector rotates 180 degrees; finally, the telescopic ends of the stop cylinders 11 in the two stop units are driven outward to drive the two stop pins 12 to move forward, so that the front ends of the two stop pins 12 are respectively inserted into the two stop holes 131 to prevent the connector from rotating and shifting during processing, and then the processing equipment located below the connector can be controlled to process the top of the connector.

[0044] After the processing is completed, the telescopic end of the traction cylinder 2 in each clamping unit is driven to extend outward, and then the four pressing blocks 6 are driven away from the connecting head in the same way. After that, the connecting head will fall downward by its own gravity to realize automatic discharge.

[0045] The utility model only needs two traction cylinders 2 to drive four pressing blocks 6 to work at the same time, and the two traction cylinders 2 are placed below the connecting head, so it simplifies the structure and reduces the volume, and can effectively avoid interference with the processing equipment to facilitate processing; in addition, it also has a flipping function, which can automatically change position to adapt to the processing equipment without removing the connecting head, thereby simplifying the operation and improving the processing efficiency.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
