Description

TECHNICAL FIELD

[0001] The application relates to the technical field of nut tapping, and in particular to a nut drilling device. BACKGROUND

[0002] The nut drilling device is used for tapping nuts. The nut drilling device comprises a feeding machine, a rotating chuck and a tapping tool. The feeding machine transports nuts to be tapped into a clamping groove of the rotating chuck. The rotating chuck rotates to move the nuts to be tapped in the clamping groove to below the tapping tool. The rotating chuck is rotated to start the tapping tool to tap the nuts to be tapped below the tapping tool. After tapping is completed, the rotating chuck is rotated, and the tapped nuts fall off the rotating chuck.

[0003] In order to avoid that the nuts to be tapped rotate in the clamping groove during tapping, the shape of the clamping groove on the rotating chuck is matched with the shape of the nuts. Therefore, the clamping groove on the rotating chuck can only be applied to a few nuts with similar sizes. Meanwhile, the clamping groove and the rotating chuck are integrated in the prior art. Therefore, one rotating chuck can only be applied to a few nuts with similar sizes. If a manufacturer needs to process nuts with multiple sizes, the manufacturer needs to prepare multiple rotating chucks, thereby increasing the production cost of the manufacturer. SUMMARY

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] The nut drilling equipment provided by the embodiments of the present application can solve the problem of high nut tapping production cost in the related art.

[0031] Please refer to Figures 1 to 6 A nut drilling equipment, comprising:

[0032] The rotating chuck 1 is cylindrical.

[0033] A plurality of limiting structures 2 are circumferentially arranged on the rotating chuck 1 along the edge of the rotating chuck 1, such as the twelve limiting structures 2 shown in the figure. Figure 1 The limiting structure 2 comprises:

[0034] A mounting port 21 is arranged along the edge of the rotating chuck 1, and the mounting port 21 is a square port opened from the side of the rotating chuck 1 to the center direction of the rotating chuck 1.

[0035] A fixing port 22 is arranged in the mounting port 21, and the number of the fixing port 22 is two, and the fixing port 22 is located on both sides of the side wall of the mounting port 21.

[0036] A mounting block 23 can be inserted into the mounting port 21, and the mounting block 23 has a clamping space for fixing the nut, and the mounting block 23 extends to the direction of the fixing port 22 and forms a boss.

[0037] When the mounting block 23 is inserted into the mounting port 21, the boss of the mounting block 23 is located in the fixing port 22.

[0038] The mounting hole 21 is opened towards the center of the rotary chuck 1, the fixing hole 22 is opened along the height direction of the rotary chuck 1, and the fixing hole 22 does not penetrate the rotary chuck 1, avoiding the mounting block 23 from falling out of the rotary chuck 1 along the height direction of the rotary chuck 1;

[0039] The fixing hole 22 is opened along the height direction of the rotary chuck 1, that is, the mounting block 23 is inserted into the mounting hole 21 along the height direction of the rotary chuck 1 during installation, and the fixing hole 22 is opened along the height direction of the rotary chuck 1 because the rotary chuck 1 rotates around the center during processing, so as to avoid the rotary chuck 1 from rotating and causing the mounting block 23 to fall out of the mounting hole 21.

[0040] The limiting structure 2 further comprises a socket 24 and a plug 25.

[0041] The plug 25 is slidingly connected in the rotary chuck 1, the socket 24 is arranged on the mounting block 23, and the plug 25 can be inserted into the socket 24.

[0042] A plurality of through holes are further arranged on the rotary chuck 1, the number of the through holes is the same as that of the limiting structures 2, and the plug 25 can be inserted into the socket 24 through the through hole.

[0043] Further comprising a connecting ring 3.

[0044] The plug 25 extends towards the center of the rotary chuck 1 and extends out of the rotary chuck 1, and forms a protrusion. Figure 1 As shown, the protrusions of the plurality of plugs 25 are connected with the connecting ring 3.

[0045] The limiting structure 2 further comprises a guide rod 26.

[0046] The guide rod 26 penetrates the mounting block 23, and the guide rod 26 extends along the edge of the rotary chuck 1, so that the mounting block moves along the edge of the rotary chuck 1, and the plurality of mounting blocks are inserted into the socket 24 by rotating the connecting ring 3.

[0047] The limiting structure 2 further comprises a spring 27, and two ends of the spring 27 are respectively connected with the rotary chuck 1 and the plug 25.

[0048] The working principle of the present application is as follows:

[0049] Before installing the installation block 23, the spring 27 is elongated to push the plug out of the through hole, so the connecting ring 3 needs to be rotated to drive all the plugs 25 to retract into the through hole, at this time the spring 27 is compressed, and then the installation of the installation block 23 is carried out, first align the protrusion of the installation block 23 with the fixed port 22 and the whole installation block 23 with the installation port 21, then insert the installation block 23 along the height direction of the rotary chuck 1, and then insert the installation block 23 one by one, when the installation block 23 is located in the installation port 21, loosen the connecting ring 3, the spring 27 is elongated to push the plug out of the through hole and insert into the socket 24, all are fixed, and the installation of the installation block 23 on the rotary chuck 1 is completed;

[0050] When it is necessary to replace the installation block 23 on the rotary chuck 1, first rotate the connecting ring 3, compress the spring 27, and then the plug 25 is separated from the socket 24, then pull out the installation port 21 along the height direction of the rotary chuck 1, and then the installation block 23 is pulled out of the installation port 21, and then the installation block 23 on the rotary chuck 1 is disassembled, and finally the installation block 23 suitable for the current nut is installed on the rotary chuck 1 according to the above installation method;

[0051] In order to cope with different specifications of nuts, the manufacturer needs to prepare multiple sets of installation blocks 23 (twelve identical installation blocks 23 are a set), therefore the installation block 23 of the present application has a relatively simple design structure, the manufacturing cost of the installation block 23 is low, and the production cost of the manufacturer is also correspondingly low, and the present application does not need to prepare multiple rotary chucks 1, which also reduces the production cost of the manufacturer.

[0052] In the description of the present application, it should be noted that the terms "upper", "lower" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application. Unless otherwise specified and limited, the terms "installation", "connection", "connection" should be understood broadly, for example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the connection between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
