Description

Technical Field

[0001] The utility model relates to the technical field of tapping machines, in particular to a tapping machine for precision parts processing. Background Art

[0002] A tapping machine is a general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. It is also called a drilling machine, a punching machine, a hole-drilling machine, a through-hole machine, etc. It achieves the desired effect by drilling holes in precision parts. When tapping, the tapping machine needs to fix the parts and then rotate the tapper to tap the parts.

[0003] For example, the application number is 201921087522.4, a tapping machine for precision parts processing, which is provided with a fixing unit, and the oil is pumped from the oil tank to the hydraulic cylinder by a hydraulic pump, so that the telescopic rod is extended from the hydraulic cylinder, so that the upper fixing block and the lower fixing block cooperate with each other to fix the parts, ensuring that the parts will not loosen and will not affect the subsequent processing;

[0004] It has the following problems:

[0005] If the upper fixing block and the lower fixing block fit the outer wall of the part when the part is clamped, the part will be stably clamped by the upper fixing block and the lower fixing block. If the shape of the part is irregular, the clamping of the part by the upper fixing block and the lower fixing block may cause the protrusions on the outer wall of the part to be squeezed and damaged. This will limit the range of parts applicable to the device to those with specified shapes and smooth surfaces, thereby reducing the range of parts applicable to the device. If the clamped part is cylindrical and the diameter of the cylindrical part is small, the upper fixing block and the lower fixing block will clamp the part at a single point. In this way, the part is clamped at two points by the upper fixing block and the lower fixing block. The part clamped at two points is easily squeezed out from the upper fixing block and the lower fixing block due to uneven force, thereby making the part not stably clamped.

[0006] Therefore, those skilled in the art provide a tapping machine for precision parts processing to solve the problems raised in the above background technology. Utility Model Content

[0010] As a further solution of the utility model, the precision parts clamping assembly includes a turntable rotatably connected to the tapping box and a servo motor fixedly arranged in the workbench, the output end of the servo motor passes through the workbench and docks with the turntable in the tapping box, a slide groove is opened on the turntable, and the slide grooves are sequentially provided with Dorgons, and sliders are slidably connected in the slide grooves, and a clamping block is fixedly arranged on the slider.
