Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a sleeve tapping device. Background Art

[0002] Tapping is to use a certain torque to screw the tap into the bottom hole to be drilled to produce internal threads. At present, with the widespread application of CNC machine tools, improving production and manufacturing capabilities has become a common goal pursued by the mechanical processing industry. CNC lathe thread manufacturing is becoming more and more widely used, but it is difficult to control during the tapping process. Reducing the cutting speed and reducing the feed rate will reduce the thrust of the tap, and the accuracy of the thread produced will be greatly reduced. The feed speed is too fast, resulting in excessive torque, which increases the clamping requirements for the workpiece. Once the force is offset, the defective rate of the workpiece will increase. Utility Model Content

[0003] In summary, in order to overcome the deficiencies of the prior art, the utility model provides a sleeve tapping device.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sleeve tapping device, comprising a machine platform, a rotating disc for driving a workpiece to move and a control mechanism for controlling the rotation of the rotating disc are arranged on the machine platform, a loading station, a tapping station, a through gauge station and a unloading station are arranged on the machine platform, a positioning mechanism is arranged below the tapping station, a tapping mechanism is arranged above the tapping station, a plurality of material placement holes are evenly distributed on the outer circumference of the rotating disc, the positioning mechanism comprises a mounting seat arranged below each material placement hole, the mounting seat comprises a positioning inner cavity and a shock absorbing member arranged in affixed with the positioning inner cavity, the shock absorbing member is detachably connected to the mounting seat, a mounting frame is arranged on one side of the tapping station, the positioning inner cavity is arranged corresponding to an opening on one side of the mounting frame, the positioning mechanism also comprises a driving assembly and a positioning assembly arranged on the mounting frame, the positioning assembly comprises a positioning block and an elastic resistance member arranged at the front end of the driving assembly, a mounting hole adapted to the elastic resistance member is arranged at the front end of the positioning hole, and the elastic resistance member is detachably connected to the mounting hole.

[0005] By adopting the above technical scheme, the use of shock-absorbing parts and elastic resistance parts for clamping has a buffering effect compared to fixed clamping, and is not easily subject to force vibration that causes poor tapping, so that the sleeve workpiece is always in a coaxial state with the tapping mechanism in the tapping state, and the defective rate is low. At the same time, the shock-absorbing parts and elastic resistance parts can be detachably connected, which is convenient for maintenance and replacement. At the same time, they can be replaced according to different sleeve specifications, and have a wider applicability.

[0006] The utility model is further configured that: the front end of the elastic abutment member is provided with an arc-shaped concave surface adapted to the workpiece.

[0007] By adopting the above technical solution, the arc-shaped concave surface fits the sleeve more closely.

[0008] The utility model is further configured as follows: the lower end of the mounting seat is opened, an annular receiving platform is provided below the rotating disc, a chip removal groove is provided at a position of the annular receiving platform corresponding to the positioning inner cavity, and the width of the chip removal groove is smaller than the outer diameter of the workpiece and larger than the inner diameter of the workpiece.

[0009] By adopting the above technical solution, the workpiece rotates with the rotating disc, and the lower end of the workpiece moves along the annular receiving table. When it moves to the position of the chip groove, the tapping mechanism taps the inner wall of the sleeve, and the generated debris falls into the chip groove from the opening at the lower end of the mounting seat, which is convenient for centralized cleaning and keeps the machine clean.

[0010] The utility model is further configured as follows: the chip groove is annularly arranged from below the tapping station to below the through gauge station, and one end of the chip groove corresponding to the tapping station is higher than one end corresponding to the through gauge station, and one end of the chip groove corresponding to the through gauge station is open.

[0011] By adopting the above technical solution and setting it inclined, it is convenient for cleaning.

[0012] The utility model is further configured as follows: the outer diameter of the annular receiving platform is consistent with the rotating disc, a dust cover is arranged outside the annular receiving platform, and an opening matched with the positioning block is arranged on one side of the dust cover corresponding to the positioning component.

[0013] By adopting the above technical solution, the dust cover can ensure that the debris and dust fall into the chip groove in the tapping state, and avoid flying out of the dust cover.
