[0015] The present invention will be described in detail below with reference to the accompanying drawings.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] See Figures 1 to 4The utility model provides a thread processing device for a locking nut, which includes a base 1 and a pick-and-place assembly 6. A turntable 2 driven by a motor is provided above the base 1. Positioning blocks 3 are evenly distributed along the circumference of its axis on the upper end of the turntable 2. The positioning blocks 3 are provided with hexagonal positioning grooves. The positioning grooves can limit the rotation of the locking nut for thread processing. The turntable 2 and the positioning grooves are provided with through-holes. A stop column 4 and a tapping machine 7 are provided on the front and rear sides of the machine base 1 respectively. The front end of the stop column 4 is longitudinally provided with a concave slide 5, which can be connected to the vibrating disk so that the locking nut can be continuously transported and push the locking nut on the rear side to the stop column. The pick-and-place assembly 6 is used to grab the locking nut on the stop column 4 to the front positioning groove. A pushing cylinder 8 for ejecting the locking nut in the positioning groove is provided upward on the right side of the machine base 1. The piston rod of the pushing cylinder passes through the through-hole and ejects the locking nut in the right positioning groove. The locking nut is transported to the stop column and remains stationary. The pick-and-place assembly grabs the locking nut on the stop column to the front positioning groove. The turntable rotates to rotate the workstation. The tapping machine threads the locking nut in the rear positioning groove. The turntable rotates to rotate the workstation. The piston rod of the ejecting cylinder passes through the through hole and ejects the locking nut in the right positioning groove.

[0018] The top of the retaining column 4 is provided with a limiting groove communicated with the slideway 5. The locking nut is transported from the slideway to the limiting groove and does not move so that the assembly can be picked up and grasped.

[0019] See Figure 1 The pick-and-place assembly 6 includes a stabilizing frame 6.1 mounted on the top of the machine base 1. A longitudinal displacement cylinder 6.2 is longitudinally mounted on the top of the stabilizing frame 6.1. The piston rod end of the longitudinal displacement cylinder 6.2 is connected to a lifting cylinder 6.3. The piston rod end of the lifting cylinder 6.3 is connected to a clamping cylinder 6.4 located above the stop column 4. The rearmost locking nut is transported to a fixed position in the limit slot. The lifting cylinder drives the clamping cylinder down, which then grabs the locking nut in the limit slot. After the lifting cylinder rises, the longitudinal displacement cylinder drives the lifting cylinder and clamping cylinder backward, forcing the locking nut down into the positioning slot. The clamping cylinder then releases the locking nut. After the lifting cylinder rises and resets, the longitudinal displacement cylinder moves forward and resets.

[0020] A pipe 9 is provided at the upper end of the machine base 1 and is located on the right side of the right positioning block 3. The pipe 9 is composed of a horizontal section on the left side connected to an inclined section on the right side.
