Description
Technical Field
The utility model relates to the technical field of hardware tools, in particular to a high-precision drill chuck for a large-scale drilling machine.
Background
The drill chuck is one of the main accessories in the electric tool industry and the machine tool industry, and is widely applied to electric hand drills and drilling machines. The three main parameters of the drill chuck are precision, clamping force and clamping range, wherein the precision is used for controlling the jumping amount of a clamping handle tool so as to ensure the precision of a machined hole; the clamping force is used for ensuring that the clamped handle tool does not slip and preventing the handle tool from working due to slipping; the grip range is used to control the minimum and maximum diameters of the collet gripping tool to meet the operating requirements.
The drill chuck is structurally divided into two categories, namely a wrench type and a hand-tightening type. The wrench type drill chuck needs to be screwed by a wrench wheel and is mainly used in the machine tool industry, such as bench drills and electric hand drills. The hand-held drill chuck is mainly used on an electric hand drill. The spanner drill chuck is screwed up by the spanner wheel which is a bevel gear with an elongated force arm, so that the function of increasing torque and conveying people can be achieved in the screwing process, and the clamping force of the chuck is large. The spanner chuck has the advantages of simple structure, easy processing of parts, low price, reliable performance and the like, so the spanner chuck has wide application.
In the prior art, the drill chuck and the connecting rod for the large-scale drilling machine are mutually separated, and when the drill chuck and the connecting rod are used, the drill chuck and the connecting rod are assembled and combined, so that the drill chuck is not durable, the precision is low, and the diameter of the connecting rod is very small, so that the connecting rod is connected with drilling machine equipment through a reducing sleeve, and materials are wasted. In addition, the spanner hole on the drill chuck is unreasonable in design, and the drill bit is inconvenient to mount and dismount.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a high-precision drill chuck for a large drilling machine, which solves the technical problems.
In order to solve the problems, the technical scheme adopted by the utility model is as follows:
a high-precision drill chuck for a large-scale drilling machine comprises a drill chuck main body, wherein the lower end of the drill chuck main body is a conical chuck, a drill clamping jaw for clamping a drill bit is assembled in a central hole of the drill chuck main body, and the drill clamping jaw can penetrate out of the conical chuck downwards; the drill chuck comprises a drill chuck body, wherein a shifting ring is assembled outside the upper end of the drill chuck body, and a wrench hole is formed in the shifting ring; the method is characterized in that: the drill chuck comprises a drill chuck body, a drill chuck body and a rocker arm, wherein the top end of the drill chuck body is connected with the rocker arm; the diameter from the bottom up of rocking arm steadilys decrease, and is provided with the connector that is used for connecting drilling machine equipment on the top of rocking arm.
Preferably, 5-6 wrench holes are uniformly formed in the shifting ring.
Preferably, the surface of the drill clamping jaw is electroplated with a titanium alloy coating.
Has the advantages that: compared with the prior art, the utility model has the advantages that: 1. the rocker arm and the drill chuck main body are of an integrated structure, so that the precision is higher, the rocker arm can be connected with large drilling machine equipment without other connecting devices, the service life can be prolonged, materials can be saved, and the efficiency is improved; 2. the number of the wrench holes is increased, so that the locking capability of the drill chuck is enhanced, and the drill bit is easier to disassemble when separating machinery; 3. the surface of the drill clamping jaw is electroplated with the titanium alloy coating, so that the hardness is higher, the appearance is more attractive, and the service life is longer.

Detailed Description
The utility model is further described with reference to the following figures and detailed description.
Example 1:
referring to fig. 1, the high-precision drill chuck for a large-scale drilling machine according to the present embodiment includes a drill chuck body 3, a conical chuck 2 is disposed at a lower end of the drill chuck body 3, a drill clamping jaw 1 for clamping a drill is assembled in a center hole of the drill chuck body 3, and the drill clamping jaw 1 can penetrate out of the conical chuck 2. The surface of the drill clamping jaw 1 is electroplated with a titanium alloy coating, so that the hardness is higher, the appearance is more attractive, and the service life is longer.
The drill chuck is characterized in that a shifting ring 4 is assembled outside the upper end of the drill chuck main body 3, 5-6 wrench holes 5 are uniformly formed in the shifting ring 4, the number of the wrench holes 5 is increased, the locking capacity of the drill chuck is enhanced, and a drill bit is easy to detach when a machine is separated. The top end of the drill chuck main body 3 is connected with a rocker arm 6, and the drill chuck main body 3 and the rocker arm 6 are connected into an integral structure; the diameter from the bottom up of rocking arm 6 steadilys decrease, and is provided with the connector 7 that is used for connecting drilling machine equipment on the top of rocking arm 6.
