Description

Technical Field

[0001] The utility model relates to the technical field of riveting equipment, in particular to riveting equipment for a piston rod limiting ring seat. Background Art

[0002] The function of the limit ring is to limit the position of the piston rod and ultimately adjust the stroke of the shock absorber. Because the strength of the limit ring directly affects the safety of the vehicle, the pull-off strength of the limit ring is a very important characteristic in the manufacture of the shock absorber. The installation of the piston rod limit ring is generally done by riveting. First, the piston rod is grooved, and then the limit ring is squeezed into the groove of the piston rod by a press. In previous production, each riveting operation required moving the tooling into position, and after the riveting was completed, the piston rod needed to be removed. This cycle was repeated, resulting in low production efficiency, high labor intensity for workers, and a lack of detection function. It can only be manually inspected after processing, which is prone to product quality problems. In response to the above defects, this application is proposed. Utility Model Content

[0016] The following description is only used to disclose the utility model so that those skilled in the art can implement the utility model. The embodiments described below are only for example, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not deviate from the spirit and scope of the utility model.

[0017] [Example 1]

[0018] Piston rod limit ring seat riveting equipment, such as Figure 1 , including a clamping assembly, a riveting assembly 5, a positioning platform 6 and a height detection assembly 4. The clamping assembly includes a clamping arm 2 and a clamping drive mechanism. The clamping drive mechanism can use a drive device such as a cylinder, a motor, a hydraulic cylinder, etc. In this embodiment, two cylinders are used to connect with two clamping arms 2 respectively, and a position sensor is provided. When the clamping arm 2 reaches the clamping position, the position sensor sends a command to the translation drive mechanism. The clamping arm 2 has a cylindrical clamping portion 3, and the cylindrical clamping portion 3 is used to clamp the piston rod.

[0019] The positioning platform 6 is arranged on the upper side of the cylindrical clamping part 3, and the positioning platform 6 is connected to the translation drive mechanism. When the clamping arm 2 reaches the clamping position and clamps the piston rod 7, the translation drive mechanism drives the positioning platform 6 to withdraw backwards. Figure 3As shown, the translation drive mechanism can use a servo motor (cooperating with a screw rod or a connecting rod assembly), a cylinder, an electric slide, etc. The positioning platform 6 has an open circular hole portion 62 for the piston rod to be inserted into. Specifically, the positioning platform 6 includes two positioning pieces 61, and the two positioning pieces 61 are connected by an elastic member. The thickness of the positioning piece 61 is equivalent to the width of the groove processed on the piston rod 7. In order to facilitate the installation of the piston rod, as shown in FIG. Figure 1 As shown, the opening of the circular opening portion 62 is in the shape of a bell mouth.

[0020] The height detection component 4 is used to detect the height of the upper end surface of the piston rod and determine whether the parameters of the piston rod meet the requirements. The height detection component 4 can adopt image recognition detection, laser distance meter, ultrasonic altimeter, height measuring instrument, etc. In this embodiment, a height measuring instrument with a retractable and movable pressure rod is adopted. When detecting the height, the pressure rod is extended toward the direction of the piston rod under the action of the telescopic mechanism and descends under the action of the lifting mechanism until the pressure rod is against the end surface of the piston rod to realize the height detection.

[0021] Preferably, the piston rod limit ring seat riveting device further comprises a workbench 1, on which the clamping assembly, the positioning platform 6 and the height detection assembly 4 are all arranged, and the workbench 1 can be mounted on the riveting device by bolts.

[0022] Working steps: Figure 2 , it is necessary to first groove the piston rod 7, then install it on the positioning table 6 of the equipment, fix the piston rod through the groove on the piston rod, and then install the limiting ring seat into the piston rod, such as Figure 3 , the clamping assembly clamps the piston rod, the positioning table 6 retreats, the riveting assembly 5 descends, and the riveting head rivets the limit ring seat to the groove on the piston rod. After the riveting action is completed, the riveting head will return to the initial height. The height detection assembly 4 detects the height from the limit ring seat to the end face of the piston rod, and compares it with the standard data set before production to detect whether the produced parts are qualified. If it exceeds the set tolerance, the equipment will alarm, and the operator can accurately judge whether the parts produced in this process are qualified.

[0023] Embodiment 2, based on embodiment 1, the cylindrical clamping portion 3 and the clamping arm 2 are detachably connected. The spacing between the positioning pieces 61 can be adjusted, so as to adapt to different types of piston rods.

[0024] Optionally, a grating sensor is provided on the workbench 1. When it is detected that a person is in a set position, the riveting press is not started to ensure the safety of the person.
