DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1 to 4As shown, the embodiment of the utility model provides a spherical workpiece drilling tool, which is used to clamp the spherical workpiece 100 to be drilled, so as to fix the position of the spherical workpiece 100 during the drilling process.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 The spherical workpiece drilling tool comprises a base 1, a positioning platform 2 is provided on the base 1, and the positioning platform 2 has a positioning groove 21 for accommodating the spherical workpiece 100, and two movable seats 3 are also provided on the base 1, and the two movable seats 3 are movably arranged on the base 1 and the moving directions of the two movable seats 3 are on the same straight line, and the two movable seats 3 are respectively located on the opposite sides of the positioning platform 2, and clamping members 31 are respectively provided on the movable seats 3 and the clamping members 31 are rotatably connected with the movable seats 3, and the rotating axis of the clamping member 31 is parallel to the moving direction of the movable seat 3, and the clamping member 31 is close to the positioning platform 2. One side is provided with a clamping block 32, and the base 1 is also provided with a driving component 4, and the driving component 4 is respectively connected to the two movable seats 3 in transmission, and the driving component 4 is used to drive the two movable seats 3 to approach or move away from the positioning platform 2 at the same time, and when the two movable seats 3 are driven by the driving component 4 to approach the positioning platform 2, the two clamping members 31 move close to the spherical workpiece 100 placed in the positioning groove 21 as the movable seats 3 move, and the spherical workpiece 100 is clamped by the two clamping blocks 32 abutting against the opposite sides of the spherical workpiece 100, so that the spherical workpiece 100 can be fixed on the spherical workpiece drilling tool.

[0023] Specifically, the operation steps of drilling a spherical workpiece 100 using the spherical workpiece drilling tool provided in this embodiment are as follows: first, the spherical workpiece drilling tool is installed on a drilling device such as a drilling machine, and then the spherical workpiece 100 to be processed is placed in the positioning groove 21. After the spherical workpiece 100 is placed, the driving component 4 is started to drive the two movable seats 3 to approach the positioning table 2 at the same time until the two clamping blocks 32 are respectively abutted against the two sides of the spherical workpiece 100, so that the position of the spherical workpiece 100 on the spherical workpiece drilling tool can be fixed. At this time, the drilling device can be operated to drill the spherical workpiece 100. Drilling is performed; when it is necessary to process holes at other positions on the spherical workpiece 100, the clamping member 31 is rotated to make the spherical workpiece 100 rotate in the positioning groove 21 driven by the clamping member 31, so as to adjust the position of the spherical workpiece 100. After the adjustment is in place, the drilling equipment can be operated to perform drilling processing; when the spherical workpiece 100 needs to be removed after the processing is completed, the driving assembly 4 is started to drive the two movable seats 3 away from the positioning table 2, so that the clamping block 32 is disengaged from the spherical workpiece 100, the spherical workpiece 100 can be released and the spherical workpiece 100 can be removed from the positioning groove 21. When using the spherical workpiece drilling tool provided in this embodiment to process multiple holes on a sphere, there is no need to repeatedly clamp the spherical workpiece 100, which saves the time consumed by repeated clamping operations and effectively improves the drilling efficiency of the spherical workpiece 100, and the clamping operation is simple and convenient to use.

[0024] like Figure 1 and Figure 2 As shown, the base 1 is provided with a receiving groove 11 for receiving part of the positioning platform 2, and a mounting hole is provided in the receiving groove 11, and a through hole aligned with the mounting hole is provided on the positioning platform 2. By providing the receiving groove 11 on the base 1 to receive the positioning platform 2, it is convenient to position the positioning platform 2, and after the positioning platform 2 is placed in the receiving groove 11, the through hole is aligned with the mounting hole. At this time, the positioning platform 2 can be fixed on the base 1 by passing a connecting member such as a bolt through the through hole and aligning it with the mounting hole, so as to facilitate the assembly of the spherical workpiece drilling tool.

[0025] In detail, the base 1 is further provided with two guide grooves 12, which are respectively located at opposite sides of the receiving groove 11 and are respectively connected to the receiving groove 11, and the length direction of the guide groove 12 is consistent with the moving direction of the movable seat 3, and the movable seat 3 is respectively movably arranged in the guide groove 12. The guide groove 12 is used to limit the moving direction of the movable seat 3 on the base 1, to prevent the movable seat 3 from deviating from the preset direction when moving on the base 1, causing the clamping block 32 to be misaligned with the spherical workpiece 100 placed in the positioning groove 21, to ensure that the movable seat 3 is driven by the driving assembly 4 to approach the positioning table 2 so that the two clamping blocks 32 are stably abutted against the spherical workpiece 100 and clamp the spherical workpiece 100, which is conducive to improving the reliability of the spherical workpiece drilling tooling.

[0026] like Figure 2 and Figure 4 As shown, the clamping blocks 32 are respectively provided with V-shaped grooves 33, and the V-shaped grooves 33 are located on a side of the clamping blocks 32 close to the positioning table 2. Providing the V-shaped grooves 33 on the clamping blocks 32 can increase the force points of the spherical workpiece 100 when the clamping blocks 32 contact the spherical workpiece 100, so that the position of the spherical workpiece 100 between the two clamping blocks 32 remains stable, preventing the spherical workpiece 100 from detaching during the drilling process.

[0027] Please combine Figure 2 and Figure 3 The clamping member 31 has a limit plate 34 at one end away from the positioning platform 2, and a plurality of limit grooves 35 are arranged on the limit plate 34 around the rotation axis of the clamping member 31. The movable seat 3 is also provided with a rotatable rotating rod 5, and a limit block 51 is provided on the rotating rod 5. The limit block 51 extends into one of the limit grooves 35 and abuts against the limit plate 34. The position of the clamping member 31 on the movable seat 3 can be locked by the cooperation between the limit block 51 and the limit groove 35 to limit the rotation of the clamping member 31, thereby preventing the clamping member 31 from swinging during the drilling process and affecting the operation of the drilling equipment. When the spherical workpiece 100 needs to be rotated, the clamping member 31 can be released by rotating the rotating rod 5 to make the limit block 51 exit the limit groove 35. After the clamping member 31 is rotated to adjust the spherical workpiece 100 into place, the rotating rod 5 can be rotated to make the limit block 51 enter the corresponding limit groove 35 to lock the position of the clamping member 31 again. The operation is simple and convenient.

[0028] Specifically, the movable seat 3 is further provided with a support frame 52, the support frame 52 is located on the side of the clamping member 31 away from the positioning platform 2, and the support frame 52 is provided with a through hole that matches the rotating rod 5. The support frame 52 on the movable seat 3 is used for mounting the rotating rod 5, and the rotating rod 5 cooperates with the through hole on the support frame 52 to realize the rotation connection between the rotating rod 5 and the support frame 52, ensuring that the rotating rod 5 can smoothly rotate on the movable seat 3 and lock or unlock the position of the clamping member 31.

[0029] like Figure 2 As shown, a toggle piece 53 is provided at one end of the rotating rod 5, and the end of the rotating rod 5 provided with the toggle piece 53 extends in a direction away from the supporting frame 52. By toggling the toggle piece 53 provided at the end of the rotating rod 5, the rotating rod 5 can be conveniently operated to rotate, so as to adjust the position of the limit block 51 so that the limit block 51 extends into the positioning groove 21 or exits the positioning groove 21.

[0030] In detail, the limit plate 34 is provided with a mounting rod 36, the axial direction of the mounting rod 36 coincides with the rotation axis of the clamping member 31, and the mounting rod 36 is provided with a first adjustment hand wheel 37. After the rotation rod 5 is rotated to make the limit block 51 withdraw from the positioning groove 21 to release the lock on the clamping member 31, the clamping member 31 can be rotated by operating the first adjustment hand wheel 37, and the friction between the spherical workpiece 100 and the two clamping blocks 32 can make the two clamping members 31 rotate synchronously, ensuring that the position of the spherical workpiece 100 between the two clamping members 31 remains stable when the spherical workpiece 100 is rotated.

[0031] Please refer to Figure 2 and Figure 4 The driving assembly 4 includes an adjusting screw 41 rotatably arranged on the base 1, and two threaded portions 42 with opposite rotation directions are arranged on the adjusting screw 41 at intervals. The two movable seats 3 are respectively provided with threaded holes 38 corresponding to the two threaded portions 42. When the adjusting screw 41 rotates, the two movable seats 3 can be driven to move along the axial direction of the adjusting screw 41 through the cooperation between the threaded portions 42 and the threaded holes 38. The rotation directions of the two threaded portions 42 on the adjusting screw 41 are opposite, so that the moving directions of the movable seats 3 respectively matched with the two threaded portions 42 are opposite, so that the two movable seats 3 can be driven by the driving assembly 4 to approach or move away from the positioning platform 2 at the same time, which is convenient for operation.

[0032] In this embodiment, the driving assembly 4 further includes a second adjusting hand wheel 43, and the second adjusting hand wheel 43 is sleeved on one end of the adjusting screw 41. The adjusting screw 41 can be rotated by rotating the second adjusting hand wheel 43 to adjust the position of the movable seat 3, and the rotating direction of the adjusting screw 41 can be changed by controlling the rotating direction of the second adjusting hand wheel 43, thereby adjusting the moving direction of the movable seat 3 on the base 1, so as to clamp or release the spherical workpiece 100, and facilitate the use of the spherical workpiece drilling tool.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
