For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0025] See also Figures 1 to 6 As shown, the utility model is a device for processing and fixing a spherical blank 8, comprising a base, to which two connecting plates 13 are connected, and the connecting plates 13 are connected to a processing body, and the processing body can complete the fixation of the spherical blank.

[0026] The processing body includes a support frame, which is set in a "U" shape. The support frame includes two horizontal arms 1 and a vertical plate 2. The vertical plate 2 has a certain thickness. The two horizontal arms 1 extend horizontally. A positioning assembly is arranged between the two horizontal arms 1.

[0028] The inner end of the bolt rod 7 is also connected to a movable shell, which specifically includes an upper movable shell 19 and a lower movable shell 20. The upper movable shell 19 and the lower movable shell 20 are both set to be arc-shaped, and the arc center of the movable shell coincides with the circle center of the outer fixing ring 18. There is no interference between the upper movable shell 19 and the lower movable shell 20, and the two can move along the length direction of the bolt rod 7. By adjusting the relative position of the bolt rod 7, the upper movable shell 19 and the lower movable shell 20 can perform two kinds of movements of holding and separating, thereby completing the clamping and loosening of the spherical blank 8.

[0029] The bolt rod 7 is movably connected to the upper movable shell 19 and the lower movable shell 20. When the relative position of the bolt rod 7 changes, the upper movable shell 19 and the lower movable shell 20 may rotate in space, so that the upper movable shell 19 and the lower movable shell 20 are no longer in the same plane; for this reason, four through holes are provided on the outer fixed ring, and limit rods 21 are provided on the upper movable shell 19 and the lower movable shell 20, and the limit rods 21 pass through the corresponding through holes, so that the upper movable shell 19 and the lower movable shell 20 are in the same plane; wherein, there are two limit rods 21 provided on the upper movable shell 19 and the lower movable shell 20, and the two limit rods 21 are parallel to the bolt rod 7, and the two limit rods 21 are symmetrically arranged with the bolt rod 7 as the central axis. When the relative position of the bolt rod 7 is adjusted, the limit rod 21 moves accordingly in the vertical direction, and the upper movable shell 19 and the lower movable shell 20 will not rotate, thereby not affecting the installation and disassembly of the spherical blank 8;

[0030] In order to increase the stability of holding the spherical blank 8 and avoid wear on the surface of the spherical blank 8 during the holding process, a plurality of fixing claws 22 are arranged on the inner wall of the movable shell, and the fixing claws 22 are evenly distributed along the center of the outer fixing ring 18; at the same time, the position where the inner fixing claws 22 contact the spherical blank 8 is a spherical curved surface, and an anti-skid pad 23 is arranged in the spherical curved surface, and the anti-skid pad 23 has a certain thickness, which can increase the holding stability;

[0031] Since different spherical blanks 8 may have different processing amounts, in order to meet the different processing amounts of the spherical blanks 8, a transmission assembly is provided to adjust the distance between the first positioning assembly 3 and the vertical plate 2, thereby indirectly controlling the relative position of the first positioning assembly 3 and the second positioning assembly 4;

[0032] Wherein, the transmission assembly includes a transmission shaft 14, the transmission shaft 14 passes through the vertical plate 2, and the two are connected by threads, that is, a horizontally penetrating threaded hole is set on the vertical plate 2, the transmission shaft 14 is screwed into the threaded hole, and the outer end and inner end of the transmission shaft 14 are respectively provided with a handle 15 and a transition platform 16, the transition platform 16 is movably connected with the inner end of the transmission shaft 14, and a vertical plate 17 is fixed on the first positioning assembly 3, and the extension line of the transmission shaft 14 passes through the center of the circle of the outer fixing ring 18. When the transmission shaft 14 rotates, it drives the transition platform 16 to move horizontally. When the transition platform 16 moves toward the first positioning assembly 3 until it contacts the vertical plate 17, as the transmission shaft 14 is continuously screwed, the first positioning assembly 3 can be moved toward the second positioning assembly 4. At this time, the first positioning assembly 3 and the second positioning assembly 4 cooperate to clamp and position the spherical blank 8, thereby meeting the assembly of different spherical blanks 8;

[0033] In addition, in order to facilitate the control of the horizontal feed amount of the spherical blank during processing, a feeding device is also provided below it; the feeding device is located on the base, and the feeding device is connected to the processing body, so that the horizontal feed amount of the spherical blank 8 is controlled by the feeding device, and the relative position of the above device in the horizontal direction of the work can be adjusted conveniently;

[0035] A lead screw 27 is used to control the movement of the mobile platform 11 in the straight groove. Specifically, a left cavity and a right cavity are provided on the base, and the straight groove is located between the left cavity and the right cavity.

The measuring seat 9 is connected to a measuring strip 10, and the measuring strip 10 is plugged into the measuring seat 9 and the measuring strip 10 is in a vertical state;

[0037] In this embodiment, the connecting plate 13 plays a role of supporting the processing body. In order to prevent the connecting plate 13 from hindering the movement of the first positioning component 3, a middle gap is provided on the two connecting plates 13. The middle gap extends downward from the upper end of the connecting plate 13.

The relative position between the first positioning assembly 3 and the second positioning assembly 4 is selected according to the diameter of the spherical blank 8 to be assembled and the required processing amount. After the relative position adjustment is completed, the spherical blank 8 is installed. After the relative position of the spherical blank 8 is adjusted, , first fix the nut 6 between the first positioning component 3 and the two cross arms 1, and then fix the nut 6 between the second positioning component 4 and the two cross arms 1, so as to complete the fixation of the ball 8; then, the drive motor 25 can be started, and the horizontal feed of the processing body can be controlled by the screw 27 and the moving platform 11; this device can conveniently and quickly install the spherical blank 8 in the positioning component, and can adapt to spherical blanks 8 of different diameters; after the spherical blank 8 is processed, if it is necessary to detect the processed surface of the spherical blank 8, the marking and adjustment plate can be installed on the measuring and displacement seat 9, and the sliding measuring and displacement seat 9 allows the marking strip 10 to detect the processed surface.
