Description

Technical Field

[0001] The invention relates to a stud bolt installation device, in particular to a stud bolt installation device for a pressure plate end of a vehicle air-conditioning pipe. Background Art

[0002] During the installation of vehicle air conditioners, some air conditioning pipes need to be assembled. In order to assemble these pipes together, during the production of air conditioning pipes, a pressure plate is first installed at the end of the pipe, and then a stud is installed on the pressure plate. During subsequent installation, the pressure plates at the ends of the two pipes are fixed together by the stud, thereby completing the assembly of the pipes. In the process of installing the stud on the pressure plate, the existing installation method is: the worker holds the stud in his hand and twists it on the pressure plate for a few turns to pre-install the stud on the pressure plate so that it does not fall off, and then tightens the stud with a screwdriver and installs it on the pressure plate. This installation method has the following disadvantages: 1. The operation is relatively cumbersome. During the installation process, it is necessary to repeatedly take out the stud bolts from the placement position and twist them to pre-install them on the pressure plate. Due to the large number of stud bolts that need to be installed, the workload of the workers is large; 2. The manual twisting of the stud bolts is prone to cause the stud bolts to be skewed or not vertical after pre-installation, affecting the subsequent installation of the stud bolts or causing poor installation quality of the stud bolts; 3. This operation of manually pre-installing the stud bolts on the pressure plate and then tightening the stud bolts with a pneumatic screwdriver has a low degree of automation, is time-consuming, and has low work efficiency.

[0044] Working process: Before work, first connect the vibrating plate feed track with the feed hole on the top plate of the utility model. The vibrating plate is an existing device. Then connect the air blowing pipe with the air blowing device, and the air blowing device sends air into the air blowing pipe. At the beginning of work, pour a large number of studs into the vibrating plate, and arrange the messy studs neatly through vibration. The neatly arranged studs are discharged from the vibrating plate feed track and enter the circular feed groove of the push block in sequence. When the worker presses the feed switch on the slider, the push cylinder works, pushing the push block further under the top plate, so that the circular feed groove on the bolt push block is connected to the air inlet hole on the top plate and the air outlet hole on the support plate at the same time. At this time, the push rod pushes the controller switch to make the air blowing pipe send air into the circular feed groove, and the studs are sent into the bolt arc channel of the bolt guide seat through the bolt discharge pipe, and then slide into the bottom of the straight channel connected to the bolt arc channel (the inner diameter of the straight channel is slightly larger than the outer diameter of the stud bolt at the largest point, and the wind force is not The stud bolts can be blown out of the straight channel). At this time, the worker places the pressure plate end on the air conditioning pipe where the stud bolts need to be installed on the pressure plate limit block. The pressure plate is located in the pressure plate positioning groove, and the air conditioning pipe is supported on the air conditioning pipe support groove plate. Then the worker presses the pneumatic screwdriver switch to start the pneumatic screwdriver, and at the same time moves the pneumatic screwdriver in the direction of the pressure plate limit block, so that the rotating head clamps the stud bolts. Under the guidance of the guide rod, the pneumatic screwdriver drives the rotating head to rotate and tighten the stud bolts on the pressure plate to complete the installation of the stud bolts. After the installation is completed, the slider is manually slid away from the pressure plate limit block to reset, and finally the worker removes the air conditioning pipe with the stud bolts installed. The function of the reset spring is to control the length of the rotating head extending into the bolt guide seat in a natural state, so that the rotating head does not block the connection between the straight channel and the bolt arc channel, so that the stud bolt can smoothly enter the bottom of the straight channel of the bolt guide seat after pressing the feeding switch.

[0045] Then the worker presses the feed switch to feed in the next stud bolt and repeats the installation work for the next stud bolt.
