The rollers have a single-start thread and gears at both ends. They both contact the screw thread to produce sliding motion and mesh with the internal gear ring of the nut to achieve pure rolling. This makes the machining of the rollers relatively complex.
[0003] In the prior art, when machining rollers, the workpiece to be machined is first pressed with threads using a cold rolling forming device, and then the gears at both ends of the roller are turned using a machine tool to complete the machining of the roller.

[0035] The implementation principle of the thread forming grinding wheel composite gear grinding machine in this application embodiment is as follows: During operation, under the action of the sixth driving member 7, the workpiece to be processed is fixed between the center 21 and the rotating top shaft. First, the surface of the workpiece to be processed is processed using the thread grinding wheel 20. The first driving member 25, the second driving member 9, the third driving member 23, the fourth driving member 8, and the fifth driving member 14 cooperate to process the thread. After the thread processing is completed, the third driving member 23 drives the rotating seat 11 to rotate, so that the gear grinding wheel 18 can be aligned with the workpiece to be processed. Then, the first driving member 25, the second driving member 9, the third driving member 23, the fourth driving member 8, and the fifth driving member 14 cooperate to process the gear, thereby realizing the processing of threads and teeth on the stud. By adopting this processing method, through one-time clamping and fixing, the threads and teeth can be processed simultaneously, which can make the threads and teeth more accurately connected, greatly reducing the complexity of processing the roller, making the processing of gears and threads more accurate, reducing the processing difficulty of gears, and ensuring the normal use of the roller.
[0036] Example 2; Reference Figure 5The difference between this embodiment and Embodiment 1 is that a coolant pipe 38 is installed at the axis of the rotating seat 11, and a first cooling groove 27 communicating with the coolant pipe 38 is spirally opened on the inner wall of the mounting hole 19. Multiple divergent spray holes 29 for injecting grinding fluid are spaced apart on the circumference of the threaded drive member 4, and the divergent spray holes 29 are communicating with the first cooling groove 27. A second cooling groove 35 communicating with the coolant pipe 38 is opened on the side wall of the mounting groove 17, and multiple converging spray holes 36 for injecting grinding fluid are spaced apart on the circumference of the gear drive member 3, and the converging spray holes 36 are communicating with the second cooling groove 35. A control component for controlling the switching of the converging spray holes 36 and the divergent spray holes 29 is installed on the fixed seat.
[0037] The threaded drive component 4 has a threaded connection to a first adjusting ring 32 at its end. A diverging spray hole 29 is formed through the first adjusting ring 32, and the diverging spray hole 29 is inclined away from the threaded drive component 4 in a direction away from the fixed seat. The outer wall of the threaded drive component 4 has a first connecting ring groove 28 that communicates with the first cooling groove 27, and the first adjusting ring 32 is inserted into the first connecting ring groove 28. The gear drive component 3 has a threaded connection to a second adjusting ring 33 at its end. A converging spray hole 36 is formed through the second adjusting ring 33, and the converging spray hole 36 is inclined away from the fixed seat and closer to the gear drive component 3. The outer wall of the gear drive component 3 has a second connecting ring groove 34 that communicates with the second cooling groove 35, and the second adjusting ring 33 is inserted into the second connecting ring groove 34.
[0038] The control assembly includes multiple control drive components 30 mounted on a fixed base. Each control drive component 30 is a cylinder, and a cylinder rod is telescopically connected to each control drive component 30. The control drive components 30 are divided into two groups and mounted on the thread drive component 4 and the gear drive component 3. Both the thread drive component 4 and the gear drive component 3 are fitted with a closing ring 31. The closing ring 31 is used to close the converging spray hole 36 and the diverging spray hole 29. The end of the cylinder rod is fixedly connected to the closing ring 31. The control drive component 30 is used to control the sliding of the closing ring 31. When the thread drive component 4 is in use, the closing ring 31 opens the diverging spray outlet, thereby cooling the grinding wheel 20 and the stud. Conversely, it cools the grinding wheel 18 and the stud. This design can better improve the convenience of using grinding fluid.
[0039] The outer walls of the first adjusting ring 32 and the second adjusting ring 33 are integrally formed with multiple limiting blocks 40. The adjusting ring is polygonal, and the inner wall of the closed ring 31 is provided with a limiting groove 39 that is inserted and matched with the limiting block, thereby limiting the rotation of the adjusting ring and improving the stability of the adjusting ring.
[0040] A support base 42 is fixed on the base 1, and a telescopic slider 41 is slidably connected to the support base 42. The telescopic slider 41 is arranged opposite to the thread grinding wheel 20. The telescopic slider 41 slides radially along the stud. A telescopic cylinder 43 for driving the telescopic slider 41 to slide is installed on the support base 42. Two rotating wheels 45 are rotatably connected to the support base 42. The two rotating wheels 45 are staggered, and their axis direction is consistent with the stud direction. An abutment groove 44 for pressing the stud is formed between the two rotating wheels 45.
[0041] The implementation principle of Example 2 is as follows: The first cooling tank 27 and the second cooling tank 35 can reduce the temperature of the thread drive and gear drive components 3, and also provide flow space for the grinding fluid, making the grinding of the stud smoother and improving the convenience of grinding fluid flow. By adjusting the first adjusting ring 32 and the second adjusting ring 33, the position of the converging spray hole 36 and the diverging spray hole 29 can be controlled, so that the sprayed grinding fluid can be accurately sprayed to the grinding position, better reducing the temperature of the stud and improving the convenience of using the device.
[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
