Problems solved by technology
There is a lack of new technology in the production process of connecting rods, many production and processing procedures, high cost, and it is difficult to guarantee the quality. The traditional technology uses the expansion and breaking equipment to laser cut the connecting rod and then separate the rod cover. The bolt tightening equipment connects the rod cover with bolts, and finally presses the copper sleeve into the small head hole manually with a pressing machine
There are many processing procedures, which need to occupy three sets of equipment, corresponding supporting tooling, tools and workshop space, and three operators are required, and the press-fitting equipment needs to be manually pressed, which has a low degree of automation, affects production efficiency, and restricts production rhythm. Bolt tightening equipment It is an important equipment in the production process of connecting rods, but the efficiency of existing bolt tightening equipment is low and cannot be applied to automatic production

Embodiment Construction
[0012] Such as figure 1 and figure 2 As shown, a bolt tightening device for connecting rod assembly includes a workbench for placing the connecting rod and a tightening installation plate 1 above the workbench, and the tightening installation plate 1 is provided with a large head positioning block and a small end positioning block 2. The tightening installation plate 1 is also provided with a tightening guide sleeve 4 that cooperates with the bolt tightening gun 3, and the tightening installation plate 1 is connected with a lifting drive device.
[0013] The big end positioning block includes an inner limit block 5 inside the big end hole and an outer limit block 6 outside the big end hole. Simultaneous positioning from the inside and outside of the big head hole is more accurate and reliable.
[0014] The big head positioning block also includes two tight blocks 7 that tighten the inner wall of the big end hole from the inside of the big end hole to the outside. Ensure th...

The invention relates to a bolt tightening device for connecting rod assembly. The bolt tightening device comprises a workbench for placing a connecting rod and a tightening and mounting plate arranged on the workbench; the tightening and mounting plate is provided with a large head positioning plate, a small head positioning plate and a tightening guide sleeve matched with a bolt tightening gun and is connected with a lifting drive device; the lifting drive device drives the tightening and mounting plate to move downward so as to enable the large head positioning plate and the small head positioning plate to position the connecting rod; and the bolt tightening gun tightens and mounts a bolt through the tightening guide sleeve, so that the automation degree is high, and the assembly efficiency can be effectively improved.
Description
technical field [0001] The invention relates to a connecting rod assembly equipment, in particular to a bolt tightening device. Background technique [0002] The connecting rod is an important part of the engine and an important safety part of the engine. There is a lack of new technology in the production process of connecting rods, many production and processing procedures, high cost, and it is difficult to guarantee the quality. The traditional technology uses the expansion and breaking equipment to laser cut the connecting rod and then separate the rod cover. The bolt tightening equipment connects the rod cover with bolts, and finally the copper sleeve is manually pressed into the small head hole with a pressing machine. There are many processing procedures, which need to occupy three sets of equipment, corresponding supporting tooling, tools and workshop space, and three operators are required, and the press-fitting equipment needs to be manually pressed, which has a l...
