Embodiment 1

[0032] Embodiment one is basically as figure 1 As shown, the hemming head assembly with pressure detection includes a cylindrical support 1. The support 1 has a through hole along its axial direction. The upper end of the support 1 is fixedly connected with the upper end cover 2 by screws. The lower end of the seat The lower end cover 3 is fixedly connected by screws, the lower end cover 3 is provided with a vertical via hole, and the main shaft 4 is vertically slidably connected in the seat, and the lower end of the main shaft 4 passes through the via hole of the lower end cover 3 and is connected with a piping for hemming The upper end of the head 5 and the main shaft 4 is fixedly connected with a long screw 6 through a threaded fit, the long screw 6 is covered with a spring 7, the top of the spring 7 is welded with an upper baffle 8, and the lower end of the spring 7 is welded with a lower baffle 9, A gasket is provided between the bottom surface of the head of the long scr...

Embodiment 2

[0040] The difference between embodiment two and embodiment one is: as image 3 As shown, the controller 18 is connected on the pressure display. In the present embodiment, the controller 18 adopts a model of STM32 single-chip microcomputer, and the signal input end of the controller 18 is electrically connected with the signal input end of the pressure display. At the same time, the output of the controller 18 The terminal is electrically connected to the alarm device 19. By setting the reasonable range value of the rolling force on the controller 18, the controller 18 can calculate and analyze the pressure signal value output by the pressure display. When the pressure is within the range, the controller 18 controls the alarm 19 to energize and alarm, thereby alerting the hemming operator.

Abstract

The invention relates to the technical field of automobile hemming, in particular to a hemming head assembly with pressure detection, which includes a seat body provided hollow inside, an upper end cover detachably connected to the upper end of the seat body, a lower end cover detachably connected to the lower end of the seat body, and a lower end cover detachably connected to the lower end of the seat body. There is a through hole on the cover, and a main shaft is arranged in the seat, and one end of the main shaft passes through the through hole and is connected with a hemming head, and a first pressure sensor is provided between the other end of the main shaft and the upper end cover. It is connected with a pressure display, and a tension detection unit is installed on the main shaft. In the present invention, the first pressure sensor is used to detect the pressure on the hemming head, and the tension detection unit is used to detect the tension on the hemming head, which solves the problem that the hemming head assembly cannot detect the tension on the hemming head in the prior art.

Description

technical field [0001] The invention relates to the technical field of automobile hemming, in particular to a hemming head assembly with pressure detection. Background technique [0002] At present, when performing hemming operations on doors, hoods, fenders, and sunroof top covers in the car body, the hemming head is generally used to apply hemming pressure to the pre-hemming part, and the hemming pressure of the hemming head makes the pre-hemming part Deformation occurs to form a wrapping structure. During the rolling process of the hemming head, the hemming pressure of the hemming head and the stability of the hemming pressure play a decisive role in the hemming quality, so the pressure value of the roller is detected in real time, and the hemming of the hemming head is adjusted according to the detected hemming pressure Pressure, so as to effectively control the quality of piping. [0003] In order to achieve the above solution, the utility model patent with the public...
