Detailed ways

As an important production tooling, the process board of the external machine plays the role of a mobile supporting work platform on the air conditioner assembly line. All the assembly and testing procedures of the split external machine are completed on it. Generally, the service life of the process board is required to be at least 3 or 4 years, some 7 or 8 years, working under complex load and vibration conditions for a long time, the bearings of its core parts gradually wear out, causing the process board to rotate and freeze, and the operation is not smooth, gradually making the process board damaged and unusable, and even Occurs that affect the normal operation of the line body. Composite bearings, deep groove ball bearings and thrust bearings are used in the same kind of double-layer process boards in the past. The non-integrated bearings have a general bearing capacity and are difficult to bear complex loads. They are damaged due to long-term use wear and tear.

In order to improve the bearing capacity of the craft board, cope with various complex loads and harsh environments, and improve the use experience and service life of the craft board, a double-layer craft board using a slewing bearing is designed and invented in this paper. By using this standard slewing bearing, the assembly can be simplified, the bearing capacity can be increased, and it can cope with complex loads under various complex working conditions, and at the same time, it can increase the service life, improve reliability, and improve the quality of the craft board.

As shown in Figure 3, the inside of the slewing bearing is a ball contact, and the whole can bear axial and radial loads at the same time, and can also bear the overturning moment. The process board using the standard slewing bearing can bear various complex loads and protect the upper and lower layers well. board to protect the stability of the overall structure.

As shown in Figure 4 and Figure 5, the slewing bearing has a high bearing capacity and will not be damaged. It is fixed in the middle of the upper and lower layers by bolts. The process board as a whole will be well protected, which improves the service life and reliability.

As shown in Figure 6, the slewing bearing is fastened to the lower plate by 6 M12X40 hexagon socket bolts and washers, and fastened to the upper plate by 6 M12X35 hexagon socket bolts and washers.

The structure of the double-layer process board designed and invented in this paper is shown in Figure 1, Figure 2, and Figure 7. The double-layer process board is mainly divided into three parts, 1. The upper layer plate assembly, 2. The swivel bearing, 3. The lower layer plate assembly. Bearings are connected together for rotation. The lower board assembly includes 31 bakelite boards; 32 induction strips, which cooperate with the wire body; 33 support wheel assemblies, which are composed of two deep groove ball bearings. Self-adaptive adjustment during collision, without offset and jamming; 35 metal retaining strips to protect the process board from breaking when impacted by bakelite; 36 positioning components, built-in compression springs and positioning pins, which are realized by cooperating with the upper plate component limit seat The automatic limit control of the process board rotation 90°; 37 knob seats, used in conjunction with the knob plunger of the upper board assembly, to achieve reliable and accurate positioning of the upper and lower boards, which can meet the positioning requirements of the craft board entering the hoist or other positions; 38RFID , can realize data informatization reading. The upper board assembly includes the main structure 11 bakelite board; 12 guide rails (angle guide rails and round guide rails). During the rotation of the upper board, the support wheels run tangentially with the guide rails, which have the advantages of reducing friction and wear and improving the strength of the board; 13 limit When the V-shaped groove of the position seat and the limit seat is turned over the positioning pin of the positioning component, the contraction spring is deformed to realize automatic positioning; about 14 trays are used to place the chassis of the split external machine, and the feet are placed in the top groove of the tray to prevent shaking. It is suitable for External unit below 3P; 15 knob plungers, rotating the L-shaped handle can control the positioning rod to move forward and backward, and cooperate with the knob seat hole to realize positioning; 16 Angle valves can place angles and other items; 17 Card holders, used to place quality control information card etc.

The principle of the mechanism of the double-layer process board designed and invented in this paper is as follows: when the process board is placed on the assembly line, the process board is driven in the direction of the arrow through the transmission of the double-speed chain, and guide wheels are installed at the four corners. When the line body is hit or the two boards collide, The guide wheel rotates along the track of the board. During the traveling process, when different positions have operation needs, employees can manually rotate the upper plate clockwise or counterclockwise. The slewing bearing, the support wheel and the guide rail together constitute the rotating mechanism of the craft plate. The slewing bearing bears most of the axial and radial Load and rotate. The supporting wheels and guide rails are distributed on the outer ring away from the bearing, so that the whole board is evenly loaded and easy to rotate. Whenever it rotates through 90°, the automatic positioning mechanism composed of limit blocks and positioning components will limit the upper board. Rotate and increase the rotational torque to force it to pass. The positioning component used in this paper can adjust the screw feed to adjust the spring force. Since the automatic positioning mechanism cannot guarantee complete fixation, the double-layer process board designed and invented in this paper uses a positioning device composed of a knob plunger and a knob seat, which can effectively achieve fixation. Rotate the L-shaped handle 180° and then turn it back 180° to control the positioning rod Move up and down, and cooperate with the hole of the knob seat to realize fixing and loosening, and it can be retracted freely.

The double-layer process board designed and invented in this paper can be applied not only to the split external unit, but also to the split internal unit, window machine and dehumidifier. The working principle is the same, and it can be realized by simply modifying the installation position or shape of the tray.
