Abstract
The utility model provides a multifunctional drill chuck, which comprises a drill body and a chuck jaw, wherein a fixed seat is arranged at the front end of the drill body. The fixed seat is provided with an opening through which the chuck jaw can pass, and is also provided with a quick changing joint connected and matched with the fixed seat, wherein the quick changing joint is provided with a magnet attracted and matched with the fixed seat. When performing the processing process such as hole drilling and other operation means, the drill chuck provided by the utility model enables the quick changing joint to be assembled or disassembled with the drill chuck with easy structure and rapid and easy operation by the attracting force of the magnet under the premise that the drill chuck doesn't need to be assembled or disassembled. Therefore, the drill chuck can be matched with and connected with other tools to perform multifunctional operation, increasing the work efficiency of electric tools.
Description
Technical field
The utility model relates to a kind of drill chuck, relates in particular to a kind of for example drill chuck on drilling machine or the electric drill of machining equipment and electric tool that is installed in.
Background technology
In the prior art, drill chuck is widely used on the electric tool, mainly bears the connection drill bit and carries out boring work.It comprises drill body, rotary sleeve and nut, and drill body is provided with the jaw hole of inclination, adopt between nut and the jaw to be threaded, thus directly nut rotation or drive the nut rotation by the operation rotary sleeve and drive jaw and in inclined hole, pass in and out with the clamping or the drilling tool that gets loose.Present drill chuck can only be used to connect drill bit, and can not be used in connecting other instrument.When carrying out one when comprising the boring and the process of other operational means, need on electric drill, carry out dismounting operation repeatedly, unusual trouble, and reduced the operating efficiency of electric tool.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of multi-functional drill chuck that overcomes above-mentioned defective.For this reason, the utility model is by the following technical solutions: it comprises drill body, jaw, and the drill body front end is provided with holder, and holder has the opening that passes for jaw, it also is provided with the hydraulic quick coupler that is connected with holder, and described hydraulic quick coupler is provided with the magnet that cooperates with holder attraction.
The hydraulic quick coupler of the utility model indication be meant can with the quick connection structure connecting of drill chuck, this syndeton has the connector that matches with common tool, these common tools can be bottle openers, interior six sides that cooperate with bolt head, outer six sides or the like.
Owing to adopt above technical scheme, drill chuck provided by the utility model is when comprising the process of boring and other operational means, carry out under the prerequisite of dismounting drill chuck not being carried out dismounting, suction by magnet, with simpler structure, quicker shirtsleeve operation, make hydraulic quick coupler and drill chuck dismounting to make drill chuck to be connected with other instruments, carry out multiple feature operation, improve the operating efficiency of electric tool.
Description of drawings
Fig. 1 partly cuts open schematic diagram for a kind of embodiment's of the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
With reference to accompanying drawing.The utility model comprises drill body 101, jaw 102, the drill body front end is provided with holder 103, holder has the opening 104 that passes for jaw, and it also is provided with the hydraulic quick coupler 1 that is connected with holder, and described hydraulic quick coupler is provided with the magnet 2 that cooperates with holder attraction.
With reference to Fig. 1, magnet 2 is for being located at the magnet ring of hydraulic quick coupler rear end inwall, and certainly, magnet 2 also can be to be block, is evenly distributed in the inwall of hydraulic quick coupler, so that connect more firm.In addition, magnet also can be arranged on other positions of hydraulic quick coupler inwall, but the most reasonable to be arranged on the rear end as shown in Figure 1.
The torsion that hydraulic quick coupler is accepted can be from holder, and like this, hydraulic quick coupler is provided with the configuration or the member of the transmission torsion that cooperates with holder, and holder is provided with configuration or the member that matches.In addition, the torsion that hydraulic quick coupler is accepted can such as shell, drill body or the like, like this, be provided with the configuration or the member that transmit torsion from other parts of drill chuck between them.
Present embodiment adopts is that hydraulic quick coupler cooperates with holder and accepts torsion.Rear end face 3 at hydraulic quick coupler is provided with the ring cap 4 that transmits torsion, and ring cap is provided with inside protruding key 5, and holder is provided with the axial notch 105 that matches.The structure of this transmission torsion, relatively simple for structure, can reduce the manufacturing cost of entire product.Certainly, the structure of transmitting torsion also can be molded directly within on the main body of hydraulic quick coupler, such as adopt modes such as limit, keyway, tooth to transmit torsion with holder.
Ring cap is provided with hole 6 in Fig. 1, and the rear end face of hydraulic quick coupler is provided with the protruding key 7 of patchhole.Like this, can reinforce being connected of ring cap and hydraulic quick coupler.
Excircle at hydraulic quick coupler also can be provided with flexible boot 23.
Claims (5)
1, a kind of novel multifunctional drill chuck, comprise drill body, jaw, it is characterized in that the drill body front end is provided with holder, holder has the opening that passes for jaw, it also is provided with the hydraulic quick coupler that is connected with holder, and described hydraulic quick coupler is provided with the magnet that cooperates with holder attraction.
2, a kind of novel multifunctional drill chuck as claimed in claim 1 is characterized in that hydraulic quick coupler is provided with the configuration or the member of the transmission torsion that cooperates with holder, and holder is provided with configuration or the member that matches.
