After the use, as long as the fingers leave the wrench, the square head retracts into the half shell under the action of the compression spring, so that the wrench is automatically separated from the chuck. The device is simple to operate and reasonable in design, the wrench is forced to be separated from the chuck by utilizing the operating characteristics, the safety of a machine tool and personnel is ensured, and the risk factors are eliminated.
Description
Technical Field
The utility model belongs to the technical field of mechanical design and manufacturing process, a lathe chuck withdraws from spanner automatically is related to.
Background
The chuck is used as a special tool for a lathe, is used for clamping bar materials, and is very commonly used in machine manufacturing. Common mechanical chucks are divided into three-jaw chucks and four-jaw chucks, and the three-jaw chucks are widely applied due to the self-centering function.
Special fixed wrenches must be used for the chuck operation. The existing fixed wrench has the advantages of simple structure and convenient use, and is used as an essential accessory of a machine tool together with a chuck.
However, in the process of operating the lathe, especially for beginners, the wrench is often left in the fastening hole of the three-jaw chuck, and when the lathe is opened, the wrench and the three-jaw chuck rotate simultaneously and are thrown out, so that equipment damage and personnel injury are caused.
Therefore, in order to solve the defects, the automatic withdrawal wrench for the lathe chuck is specially designed, and the three-jaw chuck can be automatically separated after the wrench is used.
Disclosure of Invention
The utility model adopts the technical scheme as follows:
an automatic withdrawal wrench for a lathe chuck comprises two half shells 1, two handles 2, four bolts 3, a square head 4, a spring 5 and an X-shaped telescopic rod system 6; the handle 2 is fixedly connected to the upper half part of the half shell 1 and is connected with the half shell 1 in an L shape, the two half shells 1 are connected through four bolts 3 to form a barrel-shaped cavity structure with a square hole at the bottom, a square head 4 is arranged in the cavity, and a spring 5 is sleeved at the lower end of the square head 4 in an empty mode; the upper end of the square head 4 is fixedly connected with one end of an X-shaped telescopic rod system 6, and the other end of the X-shaped telescopic rod system 6 protrudes out of the semi-shell 1.
The outline of the square head 4 is a big cylindrical structure 4-1, a small cylindrical structure 4-2 and a cuboid structure 4-3 from top to bottom; the large cylindrical structure 4-1 of the square head 4 can freely slide in the round hole cavity of the half shell 1, the outer contour of the small cylindrical structure 4-2 of the square head 4 is wrapped by the spring 5, and the cuboid structure 4-3 of the square head 4 can freely slide in the round hole cavity of the half shell 1.
The X-shaped telescopic rod system 6 comprises a small pin 6-2, a large pin 6-3, a long pin 6-4 and a plurality of short rods 6-1; the middle part of the short rod 6-1 is hinged through a large pin 6-3 to form an X shape, two ends of the short rod 6-1 are hinged through a small pin 6-2, and the X-shaped telescopic rod system 6 is hinged on the inner side of the half shell 1 through a long pin 6-4.
The utility model has the advantages that: the utility model provides an automatic spanner that withdraws from of lathe chuck, finger must exert force in X type telescopic link system before using makes the square head stretch out half casing square and can act on the chuck screw, as long as the finger leaves X type telescopic link system, the square head can not continue to insert in the half casing and drop automatically, makes the spanner break away from the chuck, avoided practice student's maloperation to open the main shaft rotation and make the spanner throw away and cause the personage loss, ensured teacher's student and equipment safety, also got rid of potential unsafe factor.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, an automatic withdrawal wrench for a lathe chuck comprises two half shells 1, two handles 2, four bolts 3, a square head 4, a spring 5 and an X-shaped telescopic rod system 6; the handle 2 is fixedly connected to the upper half part of the half shell 1 and is connected with the half shell 1 in an L shape, the two half shells 1 are connected through four bolts 3 to form a barrel-shaped cavity structure with a square hole at the bottom, a square head 4 is arranged in the cavity, and a spring 5 is sleeved at the lower end of the square head 4 in an empty mode; the upper end of the square head 4 is connected with one end of an X-shaped telescopic rod system 6 and fixedly connected, and the other end of the X-shaped telescopic rod system 6 protrudes out of the semi-shell 1.
The outline of the square head 4 is in a structure from top to bottom, namely a large cylinder 4-1 structure, a small cylinder 4-2 structure and a cuboid 4-3 structure; the large cylindrical structure 4-1 of the square head 4 can freely slide in the round hole cavity of the half shell 1, the outer contour of the small cylindrical structure 4-2 of the square head 4 is wrapped by the spring 5, and the cuboid structure 4-3 of the square head 4 can freely slide in the round hole cavity of the half shell 1.
The X-shaped telescopic rod system 6 comprises a small pin 6-2, a large pin 6-3, a long pin 6-4 and a plurality of short rods 6-1; the middle part of the short rod 6-1 is hinged through a large pin 6-3 to form an X shape, two ends of the short rod 6-1 are hinged through a small pin 6-2, and the X-shaped telescopic rod system 6 is hinged on the inner side of the half shell 1 through a long pin 6-4.
The utility model discloses a working process: use this lathe chuck during automatic withdrawal from spanner, the handle is gripped to the operator's both hands, with two quarter butts of thumb and forefinger hard extrusion X type telescopic link system head of one of them hand, X type telescopic link system promotes the square head downwards when making the quarter butt draw close in opposite directions, the square head slides down and compression spring along half shell cavity, make the square head expose half shell, the square head can insert chuck screw position this moment, both hands begin the twist grip, it is rotatory to drive half shell and square head, finally realize that the chuck screw is not hard up or fastening.
