The chuck can be in a closed state all the time in the rotating process of the safety chuck transmission shaft, daily maintenance of equipment is reduced, the working efficiency is improved, and the operation safety performance of the equipment is improved.

Description

Technical Field

[0001] The invention relates to the field of chuck tools, in particular to a safety chuck closer. Background Art

[0002] As we all know, a safety chuck is an object that can withstand high torque and provides fast, safe, accurate and easy connection and disconnection for frequent transmission actions. One type of safety chuck is equipped with a reversible chuck. During use, the chuck is not flexible to flip, cannot be flipped open and closed, and flips open automatically, causing the crimping shaft to fall off, which reduces work efficiency and creates unsafe operation factors. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a safety chuck closer, which reduces the daily maintenance of the equipment and improves the operational safety performance of the equipment.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a safety chuck closer is provided with a fan-shaped seat, characterized in that an annular groove is provided in the middle of the fan surface of the fan-shaped seat, the annular groove is concentric with the fan-shaped seat, there are left ear seats on the groove edges on both sides of the left end of the annular groove, there are right ear seats on the groove edges on both sides of the right end of the annular groove, there are middle ear seats on the groove edges on both sides of the middle part of the annular groove, a middle plug bolt passes through the hole on the ear piece of the middle ear seat to fix the middle bearing in the middle of the two ear pieces, a left plug bolt passes through the hole on the ear piece of the left ear seat to fix the left bearing in the middle of the two ear pieces, and a right plug bolt passes through the hole on the ear piece of the right ear seat to fix the right bearing in the middle of the two ear pieces.

[0005] The beneficial effect of the present invention is that the chuck can be kept in a closed state during the rotation of the safety chuck transmission shaft, thereby reducing the daily maintenance of the equipment, improving the work efficiency, and improving the operational safety performance of the equipment.

DETAILED DESCRIPTION

[0011] In the figure, the present invention is provided with a fan-shaped seat 1, and an annular groove 17 is processed in the middle of the fan surface of the fan-shaped seat 1, and the annular groove 17 is concentric with the fan-shaped seat 1, and a left ear seat 3 is arranged on the groove edges on both sides of the left end of the annular groove 17, and a right ear seat 2 is arranged on the groove edges on both sides of the right end of the annular groove 17. There are middle ear seats 4 on the groove edges on both sides of the middle part of the annular groove 17, and a middle plug bolt 5 passes through the hole on the ear piece of the middle ear seat 4 to fix the middle bearing 9 in the middle of the two ear pieces, and the left plug bolt 6 passes through the hole on the ear piece of the left ear seat 3 to fix the left bearing 10 in the middle of the two ear pieces, and the right plug bolt 7 passes through the hole on the ear piece of the right ear seat 2 to fix the right bearing 8 in the middle of the two ear pieces. The first mounting hole 11 and the second mounting hole 12 are respectively processed on the left and right sides of the arc inner edge of the inner side of the fan surface of the fan-shaped seat 1, and the third mounting hole 13 and the fourth mounting hole 14 are processed from top to bottom on the left side of the fan-shaped seat 1, and the fifth mounting hole 15 and the sixth mounting hole 16 are processed from bottom to top on the right side of the fan-shaped seat 1.

[0012] When in use, the safety chuck closer is installed at the lower part of the safety chuck, between the safety chuck chuck and the safety chuck bearing seat. When the transmission shaft of the safety chuck rotates, the right bearing 8 or the left bearing 10 of the safety chuck closer will lift the chuck in the open state, so that it is closed in place and locks the curling shaft. The middle bearing 9 of the safety chuck closer can keep the chuck in the closed state during the rotation of the safety chuck transmission shaft.

Claims

1. A safety chuck closer having a fan-shaped seat, characterized in that: There is an annular groove in the middle of the fan surface of the fan-shaped seat, which is concentric with the fan-shaped seat. There are left ear seats on the groove edges on both sides of the left end of the annular groove, right ear seats on the groove edges on both sides of the right end of the annular groove, and middle ear seats on the groove edges on both sides of the middle of the annular groove. The middle plug bolt passes through the hole on the ear piece of the middle ear seat to fix the middle bearing between the two ear pieces, the left plug bolt passes through the hole on the ear piece of the left ear seat to fix the left bearing between the two ear pieces, and the right plug bolt passes through the hole on the ear piece of the right ear seat to fix the right bearing between the two ear pieces.
