[0018] See also Figure 1 and Figure 2 A floating outer ring thread rolling device, characterized in that it includes a first drive mechanism 19 and a second drive mechanism 20, wherein the second drive mechanism 20 is arranged at the upper end of the first drive mechanism 19; wherein the first drive mechanism 19 is used to fix the workpiece 13, and the second drive mechanism 20 adjusts the position of the first drive mechanism 19, thereby achieving more convenient installation and debugging.
[0019] The first driving mechanism 19 includes a transverse sliding plate 3, an electric cylinder 1, an active wedge 10, a swing arm 12 and an outer shell 4. One end of the electric cylinder 1 is installed at a position close to the edge of the upper end surface of the transverse sliding plate 3, and the installation direction is consistent with the length direction of the sliding plate. A connecting piece is installed at the telescopic end of the electric cylinder 1. One end of the connecting piece is connected to the telescopic end of the electric cylinder 1, and the other end passes through the outer shell 4 to form a sliding connection with the active wedge 10. The part connected to the active wedge 10 is an H-shaped structure, and a T-slot and a connecting piece are provided at the end of the active wedge 10. The active wedge 10 can be slid out of the T-slot when disassembled. There are two swing arms 12, both of which are arc-shaped structures, which are symmetrically hinged on both sides of the active wedge 10. The swing arm 12 is hinged to the upper end surface of the transverse sliding plate 3. The two ends of the swing arm 12 are respectively equipped with a thread rolling wheel 14 and a driving wheel 11. The hinge position is biased to the middle position to facilitate the swing of the thread rolling wheels 14 and the driving wheel 11 at both ends to achieve a tightening or relaxing state. The active wedge 10 is a trapezoidal structure, in which the driving wheel 11 of the swing arm 12 and the active wedge are The inclined surfaces on both sides of the block 10 form a sliding connection. When the electric cylinder 1 pushes the active wedge block 10 to move away from the electric cylinder 1 through the connecting piece, the driving wheel 11 rolls along the inclined surfaces on both sides of the active wedge block 10 through the lever principle, and the corresponding thread rolling wheels 14 are tightened inward respectively, squeezing and deforming the workpiece 13, and finally squeezing a circle of uniform tooth-shaped grooves on the surface of the workpiece 13. Otherwise, they are separated. A limit block is installed at the end of the active wedge block 10 away from the electric cylinder 1 and is located between the two swing arms 12, centered in the limit block. A limit roller 15 is installed and forms a rolling connection with the limit block. The workpiece 13 is installed on the limit roller 15 and the thread rolling wheel 14 for quality inspection. The limit wheel and the thread rolling wheel 14 are driven by the electric cylinder 1 to tighten the workpiece 13, otherwise it is loosened. The outer shell 4 is a special-shaped structure, which half surrounds the swing arm 12. A clamping spring 16 is installed between the side close to the swing arm 12 and the swing arm 12, so as to realize the elastic connection between the swing arm 12 and the outer shell 4, and at the same time, the clamping of the workpiece 13 is more stable, and the opening and closing action is smoother.
[0020] The second driving mechanism 20 includes a base plate 21, a first slide rail 9, a screw transmission mechanism 6, a second motor 5 and a longitudinal sliding plate 2. The first slide rail 9 is in two pieces and is parallelly and symmetrically mounted on the thread rolling machine. In cooperation with the thread rolling machine, the base plate 21 is slidably connected with the first slide rail 9 via a slider, so that the base plate 21 can move on the slide rail, thereby adjusting the thread rolling length. The screw transmission structure is centrally installed between the first slide rails 9 to provide power for the movement of the base plate 21. The power input end of the screw transmission structure is installed with a motor 5, so that the output shaft of the motor 5 rotates and drives the base plate 21 to move along the first slide rail 9 through the screw transmission. The longitudinal sliding plate 2 is installed at the upper end of the base plate 21. The upper end of the base plate 21 is installed with a longitudinal linear bearing 7, so that the base plate 21 and the longitudinal sliding plate 2 are combined into a sliding connection. The base plate 2 1 is equipped with a longitudinal floating cylinder 18 at the front end, and the telescopic end of the longitudinal floating cylinder 18 is fixed to one end of the longitudinal sliding plate 2, so that the longitudinal floating cylinder 18 drives the longitudinal sliding plate 2 to move along the front and rear direction of the bottom plate 21, which is perpendicular to the sliding direction of the bottom plate 21. The transverse sliding plate 3 is installed at the upper end of the longitudinal sliding plate 2, and the upper end surface of the longitudinal sliding plate 2 is equipped with a transverse linear bearing 8. The transverse sliding plate 3 is slidably connected with the longitudinal sliding plate 2 via the transverse sliding bearing, and the sliding direction is perpendicular to the sliding direction of the longitudinal sliding plate 2. The end of the longitudinal sliding plate 2 close to the electric cylinder 1 is equipped with a transverse floating cylinder 17, and the telescopic end of the transverse floating cylinder 17 is fixed to the transverse sliding plate 3, so that the transverse floating cylinder 17 drives the transverse moving plate to slide left and right along the transverse longitudinal moving plate.
[0021] Since the transverse sliding plate 3 is slidably connected to the longitudinal sliding plate 2 , the precision of thread rolling positioning of the workpiece 13 can be achieved by driving the transverse floating cylinder 17 and the longitudinal floating cylinder 18 as well as the screw transmission mechanism 6 .

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the terms "first", "second", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance.
[0023] See also Figure 1The working principle of the utility model is as follows: first, the motor 5 is driven, and the output shaft of the motor 5 rotates to drive the bottom plate 21 to move to the specified position through the screw transmission, and then the longitudinal floating cylinder 18 and the lateral moving cylinder are driven to accurately position the lateral sliding plate 3, and the workpiece 13 is placed between the thread rolling wheel 14 and the driving wheel 11, and the electric cylinder 1 is started. The output of the electric cylinder 1 drags the active wedge block 10 away from the electric cylinder 1 through the connecting piece. At the same time, as the active wedge block 10 moves, the driving wheels 11 on the swing arms 12 on both sides thereof roll along the active wedge block 10, and at the same time, the thread rolling wheel 14 at the other end of the swing arm 12 squeezes the workpiece 13 inward until a circle of uniform toothed grooves is squeezed out on the workpiece 13, thereby completing the thread rolling. The device is not only easy to install and has high thread rolling accuracy, but also brings greater convenience to installation, debugging and subsequent maintenance, solves the troubles of the staff, and increases production efficiency.
