[0026] Refer to Figure 1 and Figure 2 A kind of automatic press-fitting equipment for the new energy mounting sleeve according to a preferred embodiment of the present utility model includes an equipment bed body 1.

A hydraulic cylinder 5 is slidably connected to the surface of the driving mechanism 4. Two rows of hydraulic floating support cylinders 22 are also symmetrically arranged on the surface of the working platform 2. A guide positioning block 21 and a positioning pin 24 are respectively arranged between each row of hydraulic floating support cylinders 22. A pair of compression corner cylinders 23 are arranged at both ends of each row of the hydraulic floating support cylinders 22. The lower box body 3 to be processed is supported and fixed by the guide positioning block 21, the hydraulic floating support cylinder 22, the compression corner cylinder 23 and the positioning pin 24.

[0027] The driving mechanism 4 includes linear guide rails 47 arranged along two long edges of the surface of the working platform 2. There are two mutually parallel linear guide rails 47 on each long edge of the working platform 2. A transmission lead screw 45 is also arranged parallel between the two linear guide rails 47. One end of the transmission lead screw 45 is rotatably arranged on the lead screw mounting block 46, and the other end is in transmission connection with the servo motor 44;

[0028] A displacement driving block 41 is in threaded transmission connection with the surface of the transmission lead screw 45. The top of the displacement driving block 41 is fixedly connected with a hydraulic cylinder mounting plate 43. The two bottom surfaces on both sides of the hydraulic cylinder mounting plate 43 are slidably sleeved on the surface of the linear guide rail 47 through displacement sliders 42. Through the limiting and guiding action of the linear guide rail 47, the hydraulic cylinder mounting plate 43 can only move back and forth along the direction of the linear guide rail 47 under the driving action of the displacement driving block 41;

[0029] A hydraulic cylinder 5 is fixedly arranged on the top surface of the hydraulic cylinder mounting plate 43. The bottom output end of the hydraulic cylinder 5 is connected with a hydraulic rod 51 in a cylindrical structure for press-fitting and mounting the sleeve 31;

[0030] The cross-sectional shape of the bottom surface of the hydraulic rod 51 is matched with the shape of the top surface of the mounting sleeve 31 to facilitate the stability during press-fitting.

[0031] There are 4 guiding and positioning blocks 21 in total, which are used for guiding and limiting during the installation of the to-be-processed lower box body 3 to improve the installation speed;

[0032] There are two rows of the hydraulic floating support cylinders 22, with 4 in each row, which are used to provide precise and stable support and adjustment force during the installation of the to-be-processed lower box body 3, so that the stressed object can be stably supported and fixed;

[0033] There are 4 pressing corner cylinders 23 in total, which are used to improve the stability during the installation of the to-be-processed lower box body 3;

[0034] There are two positioning pins 24, which are used for locking and limiting stability during the installation of the to-be-processed lower box body 3.

[0035] The working principle of the present utility model is as follows:

[0036] During the actual use of the new energy mounting sleeve automatic press-fitting equipment of the present utility model, first place the to-be-processed lower box body 3 on the working platform 2, position the to-be-processed lower box body 3 on the positioning pin 24 with the help of the guiding positioning block 21, and the lower bottom surface of the lower box body abuts against the upper surface of the equipment working platform 2; start the pressing corner cylinder 23 to rotate and press the to-be-processed lower box body 3, and then start the hydraulic floating support cylinder 22 to make the ejector rod of the hydraulic floating support cylinder 22 float up and close to the lower surface of the mounting hole profile. Pre-assemble the mounting sleeve 31 coated with glue on the glue applicator into the mounting sleeve installation hole of the lower box body. Start the equipment. According to the previously set press-fitting points, the equipment drives the servo motor 44 to drive the transmission lead screw 45 to rotate through the signal sent by the main control PLC. The transmission lead screw 45 drives the displacement drive block 41 to slide forward. The displacement drive block 41 is firmly connected to the hydraulic cylinder mounting plate 43. The hydraulic cylinder 5 and the hydraulic cylinder mounting plate 43 are firmly connected. In this way, the servo motor 44 drives the hydraulic cylinder 5 to reach the first press-fitting point according to the set program through relevant connecting devices. After reaching the press-fitting point, the diffuse reflection external photoelectric switch first confirms whether there is a mounting sleeve 31. If the diffuse reflection photoelectric switch cannot sense the mounting sleeve 31, the equipment will alarm and stop working; if the diffuse reflection photoelectric switch can sense the mounting sleeve 31 at the known working position, the PLC sends a signal for the hydraulic cylinder 5 to press down, and the oil cylinder acts to press down the mounting sleeve 31. The pressing force is set according to different sleeve outer diameters and interference amounts. After the oil cylinder presses tightly in place, it automatically retracts to complete a cycle of press-fitting actions, and performs the next action under the drive of the program until all sleeves are press-fitted. The program ends, and the hydraulic cylinder unit assembly returns to the starting point. Turn off the switches of the hydraulic floating support cylinder 22 and the pressing corner cylinder 23, and remove the lower box body. The whole process ends, and the next lower box body can be installed to carry out the next round of press-fitting operations.
