Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to a flange-connected embedded chuck. Background Art

[0002] The flange and chuck are mostly used together on machine tools. The flange is installed on the lathe spindle, and then the chuck is installed on the flange. The rotation of the flange drives the chuck to rotate, so that the workpiece installed on the chuck can be processed.

[0003] At present, the installation method of flange and chuck is mostly to fix the chuck on the flange by bolts. However, in actual application, in order to ensure that the chuck is stably installed on the flange, at least four screws are used, and the staff uses a wrench to tighten the screws to achieve the installation positioning of the chuck.

[0004] Although the above installation method can realize the installation of the chuck on the flange, during actual installation, the outer surface of the chuck is smooth and it is easy to slide inside the flange, resulting in the threaded holes on the chuck not corresponding to the threaded holes on the flange. The position of the chuck needs to be adjusted continuously. This installation method wastes time and reduces work efficiency. Therefore, we propose a flange-connected embedded chuck to solve the above problem. Utility Model Content

[0008] The following is a further optimization of the above technical solution by the utility model:

[0009] The positioning assembly comprises a positioning plate fixedly mounted on the outer side wall of the flange body, and a positioning bolt is threadedly connected to the positioning plate.

[0010] Further optimization: a plurality of positioning screw holes are evenly arranged on the pull rod along its length direction, and the positioning bolts are adapted to the positioning screw holes.

[0011] Further optimization: a circular plate is fixedly connected to one end of the mounting groove away from the chuck, and the inner side of the circular plate is in contact with the end of the chuck, and a through hole is opened through the center of the circular plate.

[0012] Further optimization: a plurality of mounting screw holes are evenly arranged on the flange body along its circumference.

[0013] Further optimization: the chuck is provided with a plurality of connecting screw holes, and the connecting screw holes and the corresponding mounting screw holes are connected together by connecting bolts.

DETAILED DESCRIPTION

[0022] Reference Figure 1-4 As shown, a flange-connected embedded chuck comprises a flange body 1, a mounting groove 2 is provided through the center of the flange body 1, and the mounting groove 2 is matched with the mounting end of the chuck 3, and an annular groove 4 is provided on the outer wall of the mounting end of the chuck 3, at least two grooves 5 are evenly provided on one side wall of the flange body 1 along its circumference, and the grooves 5 are communicated with the mounting groove 2, and a limiting plate 6 is rotatably connected in the grooves 5, and a limiting hook 7 is integrally connected to the top of the limiting plate 6, and the limiting hook 7 is matched with the annular groove 4, a spring 8 is fixedly connected on one side wall of the limiting plate 6 away from the limiting hook 7, and the other end of the spring 8 is fixedly connected to the inner wall of the groove 5, a pull rod 9 is sleeved inside the spring 8, one end of the pull rod 9 is hinged to the limiting plate 6, and the other end of the pull rod 9 extends through the flange body 1 to its outside, and a plurality of positioning components 10 for positioning the pull rod 9 are provided on the outer wall of the flange body 1, and the positioning components 10 correspond one to one with the pull rod 9.

[0023] With this design, first, the limit plate 6 rotates under the elastic force of the spring 8, thereby driving the limit hook 7 to insert into the annular groove 4, thereby limiting the chuck 3, making it convenient to quickly install the chuck 3 on the flange body 1, avoiding random rotation, saving installation time, and improving work efficiency; at the same time, the chuck 3 is more stable after installation and is not easy to shake or fall off.

[0024] In addition, the coordination of the positioning assembly 10 and the pull rod 9 not only further enhances the firmness of the fixing of the limiting hook 7 to the chuck 3 and increases the stability of the chuck 3 , but also facilitates the disassembly and installation of the chuck 3 .

[0025] The positioning assembly 10 includes a positioning plate 101 fixedly mounted on the outer side wall of the flange body, and a positioning bolt 102 is threadedly connected to the positioning plate 101 .

[0026] The pull rod 9 is evenly provided with a plurality of positioning screw holes 103 along its length direction, and the positioning bolts 102 are matched with the positioning screw holes 103 .

[0027] When the pull rod 9 needs to be limited in position, the positioning bolt 102 is screwed into the corresponding positioning screw hole 103 to limit the position of the pull rod 9.

[0028] When it is necessary to release the position limit of the tie rod 9 , the positioning bolt 102 is screwed out of the corresponding positioning screw hole 103 to release the position limit of the tie rod 9 .

[0029] With this design, when the pull rod 9 needs to be limited, the pull rod 9 can be limited quickly and accurately by screwing the positioning bolt 102 into the corresponding positioning screw hole 103. This can ensure that the pull rod 9 remains stable in a specific position and avoids loosening or movement, thereby ensuring the stability of the limitation.

[0030] When it is necessary to release the limit on the pull rod 9, it is only necessary to screw the positioning bolt 102 out of the positioning screw hole 103 to easily release the limit, thereby improving work efficiency.

[0031] A circular plate 11 is fixedly connected to one end of the mounting groove 2 away from the chuck 3 , and the inner side of the circular plate 11 contacts the end of the chuck 3 , and a through hole is formed in the center of the circular plate 11 .

[0032] With this design, the circular plate 11 can provide additional support and stability to the chuck 3, further ensure the stability of the position of the chuck 3 in the mounting groove 2, further reduce the shaking and displacement of the chuck 3 during use, and improve the firmness of the connection between the flange body 1 and the chuck 3; in addition, a through hole is opened in the center of the circular plate 11, which can allow other parts or tools to pass through, facilitating related operations or connections.

[0033] A plurality of mounting screw holes 12 are evenly formed on a side wall of the flange body 1 close to the chuck 3 and along the circumference thereof.

[0034] With such a design, a plurality of mounting screw holes 12 are evenly opened along the circumference of the flange body 1, which not only makes the connection between the flange body 1 and the chuck 3 more secure, but also the plurality of mounting screw holes 12 provide more installation options, and a suitable position can be selected for connection according to specific needs, which helps to adapt to different installation environments and conditions and improves the flexibility of installation. At the same time, the evenly opened mounting screw holes 12 can make the chuck 3 easier to adjust and position during the installation process.

[0035] The chuck 3 is provided with a plurality of connecting screw holes 13 , and the connecting screw holes 13 are connected to the corresponding mounting screw holes 12 via connecting bolts 14 .

[0036] A plurality of fixing screw holes 15 are evenly formed on a side wall of the flange body 1 away from the chuck 3 and along the circumference thereof.

[0037] With this design, a plurality of fixing screw holes 15 are evenly opened along the circumference of the flange body 1, which not only ensures that the flange body 1 is firmly connected to other external devices and effectively prevents loosening or falling off during use, but also the evenly distributed screw holes can make the force more uniform and reduce the risk of stress concentration. At the same time, the plurality of fixing screw holes 15 provide more connection options, making installation and maintenance more flexible.

[0038] In specific use, the flange body 1 is first fixedly installed on the processing equipment, and then the mounting end of the chuck 3 is inserted into the mounting groove 2 of the flange body 1. When the mounting end of the chuck 3 is fully inserted, the chuck 3 is first moved to align the connecting screw hole 13 and the corresponding mounting screw hole 12, and then the positioning bolt 102 is screwed out from the positioning screw hole 103. In this way, the restriction on the movement of the pull rod 9 is released, and the limit plate 6 rotates under the elastic force of the spring 8, so that the limit hook 7 is inserted into the annular groove 4, thereby realizing the fixation and limitation of the chuck 3.

[0039] Then, screw the positioning bolt 102 into the corresponding positioning screw hole 103, so that the limiting hook 7 can firmly limit the chuck 3 in the annular groove 4, and then screw the connecting bolt 14 into the corresponding connecting screw hole 13 and the installation screw hole 12 to quickly and firmly connect the chuck 3 to the flange body 1.

[0040] After a period of use, when the chuck 3 needs to be replaced, first screw the positioning bolt 102 out of the corresponding positioning screw hole 103, then pull the pull rod 9, the pull rod 9 drives the limit plate 6 to rotate, the rotation of the limit plate 6 drives the limit hook 7 to rotate and rotate out of the annular mounting groove 2 and enter the corresponding groove 5. At this time, screw the positioning bolt 102 into the corresponding positioning screw hole 103 to limit the pull rod 9, thereby limiting the limit plate 6 and the limit hook 7.

[0041] Then, the mounting end of the chuck 3 is taken out from the mounting groove 2 so as to replace the chuck 3 with a new one.

[0042] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
