Embodiment 1

[0024] Such as figure 1 As shown, the riveting mechanism of the pulley retaining ring includes a pressure roller shaft 1, a mounting seat 3 and a pressure roller 4, the upper surface and the lower surface of the mounting seat 3 are planes parallel to each other, and the pressure roller shaft 1 is fixed to the side of the mounting seat 3 The pressure roller 4 is disc-shaped, and the pressure roller 4 is fixedly connected to the pressure roller shaft 1 .

[0025] The set mounting seat 3 is used to be installed on the tool holder of the existing bedroom lathe, the retaining ring is pre-pressed in the riveting ring on the side of the pulley, and then the pulley is clamped on the chuck of the lathe, and then the tool holder is adjusted position, so that the plane of the retaining ring is tangent to the side of the pressure roller 4, and then start the lathe, the pulley rotates with the chuck, and then brake the turning tool holder, so that the turning tool holder moves toward the c...

Embodiment 2

[0027] This embodiment is further improved on the basis of embodiment 1, as figure 1 As shown, the mounting seat 3 is in the shape of a cuboid, and the side surfaces of the pressure roller 4 and the connecting surface between the pressure wheel shaft 1 and the mounting seat 3 are parallel to each other.

[0028] The purpose of this setting is that when the connecting surface of the pressure roller shaft 1 and the mounting seat 3 is parallel to the adjacent side of the turning tool holder, the turning tool holder is turned so that the side of the turning tool holder is parallel to the center line of the chuck, and the pressure roller 4 is relatively The pulley is vertical, which is beneficial to adjust the position of the present invention relative to the pulley.

[0029] It also includes a connecting nut 2. The pressure roller shaft 1 is a stepped shaft with an external thread at one end. The center of the pressure roller 4 is provided with a through hole. The mounting seat 3 ...

Abstract

The invention discloses a belt wheel check ring riveting mechanism. The belt wheel check ring riveting mechanism comprises a pressing wheel shaft (1), an installation base (3) and a pressing wheel (4). The upper surface of the installation base (3) and the lower surface of the installation base (3) are planes which are parallel to each other. The pressing wheel shaft (1) is fixedly connected with the side face of the installation base (3). The pressing wheel (4) is in a disc shape, and the pressing wheel (4) is fixedly connected to the pressing wheel shaft (1). The belt wheel check ring riveting mechanism is simple in structure and convenient to manufacture. A belt wheel or a check ring is prevented from being damaged when the belt wheel and the check ring are riveted, all contact points between the check ring and the belt wheel are subjected to even force, and the rotary extrusion effect is guaranteed.

Description

technical field [0001] The invention relates to the field of mechanical processing riveting equipment, in particular to a riveting mechanism for a pulley retaining ring. Background technique [0002] In the synchronous belt transmission, in order to prevent the phenomenon of deviation caused by the non-parallel axis of the pulley, it is usually necessary to set a retaining ring on one side (or both sides) of the pulley. [0003] In the prior art, the retaining ring can be fastened and connected to the side of the pulley by screws. At this time, it is necessary to make corresponding via holes and threaded holes on the retaining ring and the pulley and assemble them. The process is complicated and the cost is high; When it is not suitable to use fasteners such as screws to connect due to the limitation of the wheel structure size and other factors, riveting, spot welding and other methods can also be used to connect the pulley and retaining ring. However, the thermal stress ge...
