As shown in fig. 1-2, the pure tower condenser tube core assembling device comprises a tube core semi-finished product 100, a sleeve mounting mechanism 200 and a baffle plate mounting mechanism 300, wherein the sleeve mounting mechanism 200 and the baffle plate mounting mechanism 300 are arranged on two sides of the tube core semi-finished product 100;
after the sleeve mounting mechanism 200 sequentially sleeves a group of sleeves on the limiting rod 110 on the tube core semi-finished product 100, the baffle plate mounting mechanism 300 sleeves baffles at the upper end of the sleeve, and two adjacent groups of baffle plates are sequentially transmitted to the limiting rod 110 in a staggered manner;
the sleeve mounting mechanism 200 comprises a plurality of groups of first bearing assemblies 1 which are arranged at equal intervals along the sleeve transmission direction and a first release assembly 2 which is synchronously transmitted with the first bearing assemblies 1 through a speed reducing mechanism 400;
the baffle plate mounting mechanism 300 is provided with a second bearing assembly 3 and a second release assembly 4 which is synchronously driven with the second bearing assembly 3 through a speed reducing mechanism 400;
the baffle plate is matched with the switching piece 31 of the second bearing assembly 3 to adjust the position under the clamping of the second clamping piece 34 of the second bearing assembly 3, so that the baffle plate can be accurately assembled on the tube core semi-finished product 100.
In this embodiment, by arranging the sleeve mounting mechanism 200 and matching with the baffle mounting mechanism 300, when the sleeve mounting mechanism 200 finishes mounting a group of sleeves, the baffle mounting mechanism 300 can clamp and sequentially mount baffles on the upper end of the sleeve in a staggered manner from the baffle conveying mechanism 600, and the effect of circulating work is achieved.
The first bearing component 1 cooperates with the first release component 2 to ensure that the first bearing component 1 can clamp the sleeve and drive the sleeve to move to a proper position on the limiting rod 110, and then the sleeve is loosened, and at the moment, the sleeve can vertically fall on the upper end of the bottom plate or the baffle plate of the tube core semi-finished product 100.
The second bearing component 3 is matched with the second releasing component 4, so that the second bearing component 3 can clamp the baffle plate and drive the baffle plate to move onto the limiting rod 110, a limiting hole on the baffle plate, which is started at a position corresponding to the limiting rod 110, can pass through the limiting rod 110, and the second releasing component 4 can enable the second bearing component 3 to loosen the baffle plate and enable the baffle plate to fall on the upper end of the sleeve; the second clamping piece 34 is matched with the switching piece 31, so that the second bearing assembly 3 can clamp the baffle plate conveniently and simultaneously drive the baffle plate to rotate 90 degrees, and the limit hole can be aligned with the limit rod 110.
Further, as shown in fig. 1-5, after three adjacent first clamping members 12 clamp a sleeve, the semi-finished die 100 will rotate 90 ° under the driving of the driving device, and after the fourth first clamping member 12 clamps a sleeve (for convenience of understanding, the first clamping member 12 is denoted as a first clamping member 12a, and the remaining three first clamping members 12 are denoted as first clamping members 12 b), the semi-finished die 100 will rotate 90 ° in the opposite direction under the driving of the driving device, and the first clamping member 12 is provided with a pressure sensor 126 at a position corresponding to the sleeve, and the pressure sensor 126 is electrically connected with the driving device.
In this embodiment, the number of the limit bars 110 on the semi-finished die 100 is four, so the number of the first bearing assemblies 1 on the sleeve mounting mechanism 200 is also four, when one of the first clamping members 12 clamps a sleeve, the first clamping member 12 located at the rear end of the sleeve in the transmission direction is far away from the limit bar 110, and the first clamping member 12 not adjacent to the first clamping member 12 has not started the sleeve mounting operation, therefore, it is required to ensure that the distance of travel of the first bearing assembly 1 in the vertical direction is greater than the length of the limit bar 110, during which the pressure sensor 126 is pressed and generates a signal to control the driving device to rotate 90 °, and the semi-finished die 100 is not interfered by the first bearing assembly 1 or the second bearing assembly 3 in the rotating process.
After the first three sleeves of the group of four sleeves have completed assembly work (i.e. the three first clamping members 12b complete clamping and discharging work), the fourth sleeve is at the right upper end of one of the limiting rods 110 (the first clamping members 12a clamp the sleeve to be subjected to installation work), meanwhile, the baffle plate is at the right upper end of the other three limiting rods 110, and along with the continued work of the sleeve installation mechanism 200 and the baffle plate installation mechanism 300, the fourth sleeve and the baffle plate simultaneously fall on the limiting rods and complete installation work, so that the installation work of the group of four and one baffle plate is completed, and in order to enable the plurality of baffle plates from bottom to top to be sequentially staggered, after the fourth sleeve completes installation work, the next first clamping member 12 completes clamping work, the semi-finished die 100 can be rotated 90 degrees along the reverse direction under the driving of the driving device, and in order to achieve the purpose, the first clamping member 12a is reversely connected with control lines in the pressure sensors 126 on the other three first clamping members 12 b.
