Description

Technical Field

[0001] The utility model relates to a positioning device for processing a support seat of a transport vehicle. Background Art

[0002] The truck plays a very important role in the logistics system of an enterprise. It is one of the simplest, most effective and most common loading and unloading and handling tools because it can load, unload, stack and transport palletized goods over short distances. The body structure of the truck is the core basic component, connecting key components such as wheels, counterweights and masts. The support seat is a combination of components installed at the bottom of the body to support the power system.

[0003] The processing of the support seat requires multiple steps, including welding, drilling, tapping and turning. In order to effectively fix the support seat for easy processing, the support seat must be fixed in a matching fixture before processing to complete the positioning.

Although this reduces the difficulty of positioning, it is not conducive to subsequent processing and transfer, so the processing is relatively inconvenient; in addition, most of the existing clamps for fixing the support seat rely on manual operation to complete the positioning of the support seat, so the operation steps are relatively cumbersome, time-consuming and labor-intensive, resulting in low processing efficiency, which needs further improvement.

[0042] Working principle:

[0043] The support seat is snapped backward between the two clamping plates 7, and the rear side of the support seat is attached to the first base 44, the second base 49, the third base block 415, and the cushion block 414 for preliminary fixation. Then, the structure on the left side of the support seat is snapped between the two fork feet 4171 on the end plate 417 to prevent vertical displacement. At the same time, the ends of the second positioning pin 45 and the third positioning pin 410 are inserted into the structure holes on the support seat. The telescopic end of the clamping cylinder 43 in the clamping unit 4 is driven to extend outward, thereby driving the front ends of the first swing arm 41 and the second swing arm 47 to swing backward toward the support seat until the second pressing block 46, the third pressing block 48, the fifth pressing block 413, and the sixth pressing block 412 are all pressed against the front side of the support seat. At this time, the ends of the second positioning pin 45 and the third positioning pin 410 are respectively inserted into the first U-shaped groove 461 and the second U-shaped groove 481.

[0044] When the sensing end of the third position sensor 416 detects that the distance between the support base and its sensing end reaches a certain value, it will drive the telescopic end of the first traction cylinder 33 in the positioning unit 3 to extend outwards, so as to drive both positioning modules to swing backwards towards the support base by means of the first rotary frame 32 until the first pressing block 36 in each positioning module presses tightly against the front side of the support base, and then the end of each first positioning pin 37 is inserted into the structural hole located on the front side of the support base; at the same time, it also drives the first side frame 38, the second side frame 310 and the baffle 312 to swing backwards until the first pressing head 39 and the second pressing head 311 both press tightly against the front side of the support base, and the baffle 312 fits against the right side of the support base.

[0045] When the sensing end of the first position sensor 313 detects that the distance between the support base and its sensing end reaches a certain value, it will drive the telescopic end of the second traction cylinder 52 in the pressing unit 5 to extend outwards, so as to drive both fourth pressing blocks 55 to swing backwards towards the support base by means of the second rotary frame 53 and the pressing beam 54 until both fourth pressing blocks 55 press tightly against the front side of the support base.

[0046] When the sensing end of the second position sensor 58 detects that the distance between the support base and its sensing end reaches a certain value, it indicates that all the fixing steps of the support base have been completed, and then the support base can be processed using welding or other processing equipment.

[0047] After the processing is completed, drive the telescopic ends of the clamping cylinder 43, the first traction cylinder 33 and the second traction cylinder 52 to contract inwards so that the second pressing block 46, the third pressing block 48, the fifth pressing block 413, the sixth pressing block 412, the first pressing head 39, the second pressing head 311, both first pressing blocks 36 and both fourth pressing blocks 55 all swing forward to reset and leave the support base, and then the support base can be taken off.

[0048] The utility model realizes the longitudinal fixing of the support base to facilitate subsequent processing and transfer, thereby facilitating the processing; in addition, it also realizes the automatic positioning of the support base, without manual operation, thereby simplifying the operation steps to achieve the effect of saving time and effort and improving the processing efficiency.

[0049] 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 foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
