[0038] Furthermore, the lifting assembly 203 includes two vertical plates 203a arranged on the rotating platform 201, two convex plates 203b arranged on the vertical plates 203a, a vertical rod 203c and a threaded rod 203d arranged between the two convex plates 203b, and a lifting plate 203e arranged on one side of the vertical plate 203a and connected to the vertical rod 203c and the threaded rod 203d, a threaded handle 203f is arranged on the threaded rod 203d, and a vertical movable groove 203g is opened on the vertical plate 203a; wherein the two vertical plates 203a are respectively fixedly connected to the two sides of the rotating platform 201, and the top and bottom of the opposite sides of the two vertical plates 203a are fixedly connected with the convex plates 203b, and the vertical rods 203c and the threaded rods 203d are fixedly connected. There are three 203c in total, one is set at the front and back between the two left convex plates 203b, and one is set at the rear between the two right convex plates 203b. The threaded rod 203d is set at the front of the right vertical rod 203c, and the bottom end of the threaded rod 203d is rotatably connected to the right bottom convex plate 203b through a bearing, and the top of the threaded rod 203d passes through the right top convex plate 203b and is fixedly connected to the threaded handle 203f; by rotating the threaded handle 203f, the threaded rod 203d can be driven to rotate, thereby adjusting the overall height of the lifting plate 203e and the flip assembly 204, so as to facilitate the connection of the drive assembly 205 and fix the gear workpiece.

[0039] Furthermore, the flip assembly 204 includes two central shafts 204a arranged on the flip frame 202a and connected to the lifting plate 203e, a directional handle 204b arranged on the central shaft 204a, a spring pin rod 204c arranged on the directional handle 204b, and two directional holes 204d arranged on the lifting plate 203e and matched with the spring pin rod 204c; wherein the two central shafts 204a are respectively fixedly connected to the two sides of the outer surface of the flip frame 202a, and the central shaft 204a is slidably connected to the inside of the vertical movable groove 203g. Since the flip frame 202a and the central shaft 204a need to move to a certain extent when the flip assembly 204 is lifted and lowered by the lifting assembly 203, The vertical movable groove 203g is provided with space for the central axis 204a to move up and down, and the length of the vertical movable groove 203g is limited. When the central axis 204a is at the highest point inside the vertical movable groove 203g, the bidirectional clamping assembly 202 is in a state of being separated from the driving assembly 205 as a whole, and the rotating flip assembly 204 will not be restricted by the driving assembly 205 at this time; on the contrary, when the central axis 204a is at the lowest point inside the vertical movable groove 203g, the connecting shaft 202d on the bidirectional clamping assembly 202 is connected to the driving assembly 205, so that when the driving assembly 205 is started, the bidirectional clamping assembly 202 can fix the gear workpiece; The central axis 204a and the lifting plate 203e are connected by a bearing, so that the flip plate and the central axis 204a can not only be lifted and lowered with the lifting plate 203e, but also have the function of rotation; the central axis 204a and the directional handle 204b are fixedly connected, the spring pin 204c and the directional hole 204d are slidably connected, and two positioning holes are respectively opened on the front and rear sides of one side of the lifting plate 203e to fix it after the bidirectional clamping assembly 202 is flipped 180 degrees.

[0040] Furthermore, the driving assembly 205 includes a storage hole 205a provided on the rotating platform 201, a driving motor 205b provided inside the storage hole 205a, and a rotating shaft 205c provided on the driving motor 205b, a spline shaft 205d is provided on the rotating shaft 205c, and a spline groove 205e matching with the spline shaft 205d is provided on the connecting shaft 202d; wherein the storage hole 205a is opened in the middle of the top of the rotating platform 201, and the driving motor 205 b is fixedly connected to the bottom of the inner cavity of the storage hole 205a, the driving motor 205b is fixedly connected to the rotating shaft 205c, the spline shaft 205d is fixedly connected to the top of the rotating shaft 205c, and the spline groove 205e is arranged at the opposite end of the two connecting shafts 202d. When the connecting shaft 202d and the rotating shaft 205c are connected together through the spline shaft 205d and the spline groove 205e, the driving component 205 can drive the two-way clamping component to adjust, so as to fix the gear workpiece.

[0041] When in use, since the gear 206c-3 is generally processed by drilling first, and then when the gear 206c-3 surface needs to be drilled, the outer side of the gear workpiece needs to be fixed, and the threaded rod 203d is driven to rotate by turning the threaded handle 203f, so that the lifting plate 203e, the central axis 204a, and the flip frame 202a move downward until the connecting shaft 202d is sleeved on the rotating shaft 205c, and then the driving motor 205b is started to drive the annular turntable 202c to rotate, and then the three L-shaped plates 202c-3 are driven to slide in the limiting sliding holes 202c-4 and approach each other until the three L-shaped plates 202c-3 are completely close to the outer wall of the gear workpiece, and the gear workpiece can be fixed. After the gear workpiece is fixed, the drill bit 102 is started to perform drilling on the fixed gear workpiece; When the drilling of the gear workpiece is completed and the tooth cutting process is required, the driving motor 205b is controlled to rotate in the opposite direction, so that the three L-shaped plates 202c-3 are separated from each other by a certain distance, and then the drilled gear workpiece is removed, and the threaded handle 203f is rotated in the opposite direction to drive the threaded rod 203d to rotate in the opposite direction, so that the lifting plate 203e, the central axis 204a, the flip frame 202a and other structures move upward until the central axis 204a moves to the highest point of the vertical movable groove 203g. At this time, the connecting shaft 202d is in a state of being completely separated from the rotating shaft 205c, and the height of the arc-shaped inner clamping plate 202c-8 is also slightly higher than the height of the rotating shaft 205c, thereby providing a flipping space for the flip frame 202a as a whole, and the spring pin rod 204c is pulled to separate it from the directional hole 204d at the current position, and the directional handle 204b, the central axis 204a, the flip frame 202a and other structures are moved upward. After 202a rotates 180 degrees, release the spring pin rod 204c to insert it into the corresponding directional hole 204d. When the flip frame 202a flips 180 degrees, the height of the flip frame 202a can be adjusted downward using the threaded rod 203d according to the above steps of clamping the gear workpiece, until the connecting shaft 202d is sleeved on the rotating shaft 205c, and then start the drive motor 205b to make the three movable rods 202c-7 and the arc-shaped inner clamping plates 202c-8 move away from each other until the three arc-shaped inner clamping plates 202c-8 are completely attached to the inner wall of the hole drilled in the gear workpiece, thereby completing the step of fixing the gear workpiece, and then use the mobile platform 104 to adjust the bidirectional flip clamping unit 200 to a suitable position, and control the bidirectional flip clamping unit 200 to rotate at a uniform speed as a whole, so that it can cooperate with the gear milling cutter 103 to cut the teeth.

[0042] The rest of the structure is the same as that of Example 1.

[0043] Example 3, reference Figure 9~Figure 11, which is the third embodiment of the present invention, and is different from the previous embodiment in that it includes: the touch-and-lock assembly 206 includes two inwardly buckled arc-shaped rotating grooves 206a arranged on the arc-shaped outer clamping plate 202c-5, and two outwardly buckled arc-shaped rotating grooves 206b arranged on the arc-shaped inner clamping plate 202c-8, and the inner parts of the arc-shaped outer clamping plate 202c-5 and the arc-shaped inner clamping plate 202c-8 are each provided with two axial grooves 206c, and the arc-shaped outer clamping plate 202c-5 and the arc-shaped inner clamping plate 202 The interior of c-8 is respectively provided with a fan-shaped area groove 206d connected with the axial groove 206c, the inward arc-shaped rotating groove 206a, and the outward arc-shaped rotating groove 206b, and two transverse movable grooves 206e connected with the axial groove 206c are provided on the arc-shaped outer splint 202c-5 and the arc-shaped inner splint 202c-8, and the interior of the arc-shaped outer splint 202c-5 and the arc-shaped inner splint 202c-8 are provided with a connecting groove 206f connected with the two transverse movable grooves 206e.

[0044] Furthermore, the touch-pressure locking assembly 206 also includes an axial rod 206c-1 arranged inside the axial groove 206c, two connecting brackets 206c-2 arranged on the axial rod 206c-1, a gear 206c-3 arranged on the axial rod 206c-1 and located between the two connecting brackets 206c-2, and a tooth plate 206c-4 arranged in the transverse movable groove 206e and meshing with the gear 206c-3, a movable plate 206c-5 connected to the tooth plate 206c-4 is arranged inside the connecting groove 206f, and a return spring 206c-6 connected to the inner wall of the connecting groove 206f is arranged on the movable plate 206c-5; wherein , the shaft rod 206c-1 is rotatably connected to the inside of the shaft groove 206c through a bearing, the gear 206c-3 is sleeved and fixedly connected to the middle part of the outer surface of the shaft rod 206c-1, and the two connecting brackets 206c-2 are sleeved and fixedly connected to the front and rear sides of the outer surface of the shaft rod 206c-1, and the transverse movable groove 206e and the tooth plate 206c-4 are slidably connected, and the top and bottom of the movable plate 206c-5 are respectively fixedly connected to the opposite sides of the two tooth plates 206c-4, and the movable plate 206c-5 and the connecting groove 206f are slidably connected. Two return springs 206c-6 are fixedly connected to the movable plate 206c-5; When the gear workpiece is fixed by using the arc-shaped outer clamping plate 202c-5 or the arc-shaped inner clamping plate 202c-8, the gear workpiece will come into contact with the tooth plate 206c-4 and squeeze it, so that the tooth plate 206c-4 and the movable plate 206c-5 will move in the transverse movable groove 206e and the connecting groove 206f, and at the same time drive the gear 206c-3 to rotate, so that the inner arc-shaped locking piece 206a-1 or the outer arc-shaped locking piece 206b-1 is firmly locked at the upper and lower parts of the gear workpiece. After the current processing step of the gear workpiece is completed, the gear workpiece needs to be taken out, and then when the arc-shaped outer clamping plate 202c-5 or the arc-shaped inner clamping plate 202c-8 is not fixed to the gear workpiece, the tooth plate 206c-4 will be free from the restriction and will no longer be squeezed by the gear workpiece, so that the tooth plate 206c-4 and the movable plate 206c-5 will automatically reset under the influence of the elastic force of the reset spring 206c-6, and at the same time, it will drive the gear 206c-3 to rotate and reset, so as to continue to fix the next gear workpiece that needs to be processed.

[0045] Furthermore, an inner arc-shaped locking piece 206a-1 connected to the connecting bracket 206c-2 is provided inside the inner arc-shaped rotating groove 206a, and an outer arc-shaped locking piece 206b-1 connected to the connecting bracket 206c-2 is provided inside the outer arc-shaped rotating groove 206b; wherein, the inner arc-shaped locking piece 206a-1 and the inner arc-shaped groove are slidably connected, and the outer arc-shaped locking piece 206b-1 and the outer arc-shaped groove are slidably connected, and the inner arc-shaped locking piece 206a-1 and the outer arc-shaped locking piece 206b-1 can be used to fix the gear workpiece by using the arc-shaped outer clamping plate 202c-5 and the arc-shaped inner clamping plate 202c-8, and the upper and lower parts of the gear workpiece can be additionally locked, thereby enhancing the firmness of the gear workpiece.

[0046] When in use, when the arc-shaped outer clamping plate 202c-5 is tightly fixed on the outer wall of the gear workpiece, when the arc-shaped outer clamping plate 202c-5 contacts the workpiece, the workpiece will relatively touch and squeeze the two tooth plates 206c-4 on the arc-shaped outer clamping plate 202c-5 to move, which will then drive the gear 206c-3, the shaft rod 206c-1, the connecting bracket 206c-2 and the inner buckled arc-shaped locking piece 206a-1 to rotate, so that the inner buckled arc-shaped locking piece 206a-1 is firmly locked at the upper and lower parts of the gear workpiece, and the gear workpiece is fixed together with the arc-shaped outer clamping plate 202c-5, thereby achieving a double fixing effect with stronger firmness; Similarly, when the arc-shaped inner clamping plate 202c-8 is used to fix tightly on the inner wall of the gear workpiece, when the arc-shaped inner clamping plate 202c-8 contacts the gear workpiece, the gear workpiece will also squeeze the two tooth plates 206c-4 on the arc-shaped inner clamping plate 202c-8, driving the gear 206c-3, the axis rod 206c-1, the connecting bracket 206c-2 and the external arc-shaped locking piece 206b-1 to rotate, so that the upper and lower external arc-shaped locking pieces 206b-1 are firmly fixed on the upper and lower parts of the gear workpiece. By fixing the side and upper and lower positions of the gear workpiece, the firmness and stability of the gear workpiece during processing are further improved.

[0047] The rest of the structure is the same as that of Example 2.
