Description

Technical Field

[0001] The present invention relates to the technical field of precision machining equipment, in particular to a high-precision positioning, fixing and adjustable disc inserting device for a grinding disc. Background Art

[0002] The grinding process is a crucial step in the production and processing of optical fiber cables. Unpolished optical fiber cable ends may have defects such as burrs and unevenness. These defects can cause signal scattering and reflection during transmission, thereby reducing signal transmission quality. In actual production, the optical fiber cable end is inserted into a grinding disc, which is then placed on a grinding machine for grinding.

[0003] At present, the Chinese utility model patent with the announcement number CN220839630 discloses an automatic insertion device for optical fiber connectors, which can realize the automatic insertion of optical fiber connectors through the coordinated work of a lifting arm, a sliding block, a rotating cylinder and pneumatic fingers. However, this patent only involves the insertion function of the optical fiber cable head, and does not solve the problem of accurate positioning and fixation of the grinding disc. In actual applications, inaccurate positioning or loose fixation of the grinding disc may cause the insertion to fail. In addition, the insertion mechanism of this patent relies only on the lifting arm and pneumatic fingers to complete the insertion of the cable head. In actual operation, if there is a deviation between the optical fiber cable head and the core of the grinding disc hole, it may cause the insertion to fail or even damage the optical fiber cable head.

[0030] The working process of a high-precision positioning, fixing and adjustable disc insertion device for a grinding disc is described below with reference to the accompanying drawings.

[0031] like Figure 2 、 3 As shown, the translation mechanism (3) for moving the grinding disc drives the grinding disc grabbing mechanism (4) to move to the grinding disc placement station (11). The first pneumatic finger (406) is ventilated to keep the grinding disc clamping jaw (408) in a clamped state, and the grinding disc (13) is clamped from the grinding disc placement station (11) and moved to the back of the grinding disc positioning plate (5). The first slide cylinder (403) is ventilated to drive the grinding disc clamping jaw (408) to move forward, so that the positioning pin (6) fixed on the grinding disc positioning plate (5) contacts the grinding disc pin hole (13). At this time, the grinding disc clamping jaw (408) is released.

[0032] like Figure 4 As shown: when the pin hole on the grinding disc (13) enters the positioning pin, the grinding disc will tilt due to the deviation generated during the grasping. At this time, the grinding disc clamping jaws (408) are ventilated and loosened, and the two rotating downward pressure cylinders (7) are ventilated to press the grinding disc (13) downward and fix it.

[0033] like Figure 5 As shown: after the positioning and fixing of the grinding disc are completed by the positioning pin (6) and the rotating downward pressure cylinder (7), the translation mechanism (9) of the cable head insertion device drives the cable head insertion device (10) to move to the cable head placement station (12), and the second pneumatic finger (1008) is ventilated to keep the cable head clamping claw (1009) in a clamped state to clamp the cable head from the cable head placement station (12) and move it to the core position of the grinding disc (13). At this time, the second slide cylinder (1004) is ventilated and extended forward and remains in an extended state, so that the cable head contacts the grinding disc (13). Then the second pneumatic finger (1008) is de-energized and released, and the limit block (1010) is used to ensure that the second pneumatic finger (1008) is not loosened to the extent that the cable head will fall off. At the same time, the third slide cylinder (1006) is ventilated and extended forward, as shown in FIG. Figure 7 As shown, the end protrusion of the cable head clamping jaw (1009) is used to push the cable head forward. At this time, since the cable head is in a free state, if there is a deviation between the cable head and the grinding disc (13), it can be adjusted to ensure the concentricity of the cable head and the hole core of the grinding disc (13) to complete accurate insertion.

[0034] The above description of the present invention and its embodiments is not intended to limit the present invention. For those skilled in the art, any design, modification, replacement, etc. made within the spirit and principles of the present invention shall fall within the scope of protection of the present invention.
