Specific embodiments
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0019] Please refer to Figures 1-8, the present utility model provides a technical solution: a bracket crimping device, including a machine table 1, on which a transfer mechanism 2 and a crimping mechanism 3 are installed. The crimping mechanism 3 is located above the end of the transfer mechanism 2. The transfer mechanism 2 includes a base 21 in the shape of a rectangular box. A linear guide rail 24 and a rodless cylinder 25 along the length direction are respectively installed in the base 21. A slider is slidably connected to the linear guide rail 24, and a transfer plate 22 is installed on the slider. The rodless cylinder 25 is used to drive the transfer plate 22 to move. A bellows dust cover 23 is connected between the tail end of the transfer plate 22 and the inner wall of the base 21. A buffer 26 extending into the inner cavity is installed at the front end of the base 21. The buffer 26 is used to buffer the impact of the transfer plate 22. Two symmetric positioning pins 28, a rotary clamping cylinder 29 and four load-bearing columns 27 are installed on the transfer plate 22 to form a positioning fixture. The bottom shell 51 and the bracket 41 to be crimped are sequentially placed on the positioning fixture, and the rotary clamping cylinder 29 is used to press and position them between the two.
[0020] The crimping mechanism 3 includes four guide columns 34. The lower ends of the guide columns 34 are fixedly installed on the machine table 1 through a support 35. An installation plate 32 is fixedly installed between the tops of the four guide columns 34. A servo press 31 is fixedly installed in the middle on the upper side of the installation plate 32. A pressure plate 33 is slidably connected to the guide columns 34. The output end of the servo press 31 is connected to the pressure plate 33 through a floating joint. Four pressure rods 36 are fixedly installed on the lower side of the pressure plate 33. A guide shaft 37 is fixedly installed at the lower end of the pressure rod 36. The pressure plate 33, the pressure rods 36 and the guide shaft 37 constitute a crimping die. The servo press 31 drives the pressing down and lifting actions of the crimping die. The guide columns 34 play a role in guiding and stabilizing the up and down movement of the crimping die.
[0021] Working principle: During crimping, first, a primary positioning is performed through the guide shaft 37 and the pin hole a42. When continuing to press down, a secondary positioning is performed through the guide shaft 37 and the pin hole b52. After the positioning is completed, the pins 43 on the bracket 41 are aligned with the jacks 53 on the bottom shell 51. The pressure rods 36 apply a downward pressure to the pins 43 and press the pins 43 into the jacks 53 to complete the crimping process. The positioning is accurate during the crimping process, which is beneficial to improving production efficiency and crimping quality.
