Abstract
The invention discloses a locking structure of a code disc of a motor encoder and a rotating shaft of a motor, comprising a code disc and a rotating shaft penetrating through a central punching hole of the code disc. The central punching hole on the code disc is also circularly provided with a plurality of axially extending claws which are clamped by a clamping device, i.e. a coil spring sleeved on the outer ring surfaces of the claws, the code disc is sleeved in the rotating shaft when the code disc is clamped, and then, the coil spring is sleeved on the outer ring surfaces of the claws. Because of certain elasticity, the coil spring in clamping has interference effect, stable locking, simple structure and convenience for assembly.
Description
Technical field
The present invention relates to the locking mechanism of a kind of motor encoder code-disc and machine shaft.
Technical background
Usually adopt over-surplus fit structure between the encoder code-disc of existing motor and machine shaft or draw-in groove 01 is set on motor as shown in Figure 1, establish the interface arrangment of fixture block 02 on the code-disc.Adopt over-surplus fit structure assembling inconvenience, of long duration loosening easily, and adopt draw-in groove fixture block structure because error is also loosening easily, thus all have certain weak point.
Summary of the invention
Technical problem to be solved by this invention just provides the locking mechanism of a kind of motor encoder code-disc and machine shaft, and locking is stable, and is effective, is difficult for loosening, simple in structure, easy to assembly between code-disc and rotating shaft.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: the locking mechanism of a kind of motor encoder code-disc and machine shaft, comprise code-disc and be installed on rotating shaft in the code-disc central hole, it is characterized in that: the central hole place also is equipped with several axially extended claws on the described code-disc, and described some claws are tightened by gripping mechanism.
Preferably, described gripping mechanism is one to be sleeved on the coil spring on the claw outer ring surface.
Preferably, described claw is 3 that uniform ring is established.
The present invention's central hole place ring on code-disc is established several axially extended claws, and described some claws are by the coil spring chucking that is sleeved on the claw outer ring surface.Only code-disc need be packed into rotating shaft when clamping code-disc, and then coil spring is locked gets final product at the claw outer ring surface, because coil spring has certain elasticity, have the interference effect during chucking, locking is stable, and is simple in structure, easy to assembly.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the fit structure schematic diagram of the locking mechanism of motor encoder code-disc of the present invention and machine shaft;
Fig. 2 is Fig. 1 vertical view.
Embodiment
As depicted in figs. 1 and 2, locking mechanism for motor encoder code-disc of the present invention and machine shaft, comprise code-disc 1 and be installed on rotating shaft 2 in the code-disc central hole, the central hole place also is equipped with several axially extended claws 3 on the described code-disc, described some claws are tightened by gripping mechanism, described gripping mechanism is one to be sleeved on the coil spring 4 on the claw outer ring surface, and claw described in the present embodiment is 3 that uniform ring is established.
Claims (3)
1. the locking mechanism of motor encoder code-disc and machine shaft, comprise code-disc and be installed on rotating shaft in the code-disc central hole, it is characterized in that: the central hole place also is equipped with several axially extended claws on the described code-disc, and described some claws are tightened by gripping mechanism.
2. the locking mechanism of motor encoder code-disc according to claim 1 and machine shaft is characterized in that: described gripping mechanism is one to be sleeved on the coil spring on the claw outer ring surface.
