[0031] An open processing box 2 is arranged on the surface of the drilling machine body 1, and a fixed block 3 which can be rotated by gears is arranged inside the processing box 2. A combination of a driving gear 41 and a plurality of adjusting gears 45 is arranged inside the processing box 2.

It is relatively simpler to adjust the parameters and is more convenient for drilling holes for valves with different hole numbers.

[0032] Embodiment 2

[0033] The main difference from the first embodiment is:

[0034] A radial drilling machine for valve processing, wherein the fixing assembly 5 includes a fixing column 51 that slides with the surface of the fixing block 3, a fixing rod 52 that slides inside the fixing column 51, a groove and a spring are used to limit the sliding distance and sliding trajectory between the fixing column 51 and the fixing rod 52, a fixing groove 53 is provided on the surface of the fixing block 3, a fixing spring 54 is fixed between the fixing column 51 and the fixing groove 53, the surface of the fixing column 51 is slidably connected with the inner surface of the fixing groove 53, the synchronization assembly 6 includes a synchronization wheel 61 fixed on the surfaces of the driving rod 42 and the transfer rod 43, a synchronization belt 62 is connected between the synchronization wheels 61, the limiting assembly 7 includes a limiting block 71 that slides with the surface of the processing box 2, the sliding trajectory between the limiting block 71 and the processing box 2 is limited by a groove provided on the surface of the processing box 2 and a spring fixed between the groove and the limiting block 71, the surface of the adjusting block 44 is provided with a limiting groove 72, the surface of the limiting block 71 has a cylindrical protrusion, and the cylindrical protrusion can be inserted into the limiting groove 7 2, the locking assembly 8 includes a locking column 81 that slides with the inside of the transfer rod 43, a locking spring 82 is fixedly connected between the locking column 81 and the transfer rod 43, an arc groove 83 is provided at the bottom of the adjusting gear 45, and a deeper cylindrical groove is present in the middle of the arc groove 83. There is a protrusion that can contact each other between the locking column 81 and the cylindrical groove. When the locking column 81 rotates, the cylindrical groove and the adjusting gear 45 can be driven to rotate by the protrusion. A sliding locking column 81 and an arc groove 83 that can contact the surface of the locking column 81 are provided between the transfer rod 43 and the adjusting gear 45. The sliding of the locking column 81 in the arc groove 83 can make it possible to change the position of the adjusting gear 45 without any obstruction. At the same time, when the locking column 81 moves to a certain position of the arc groove 83, the adjusting gear 45 can be driven to rotate by the protrusion on the surface and the friction generated, thereby prompting the driving gear 41 to rotate, so that the motor can drive and control the rotation angle of the driving gear 41.

[0035] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0036] During operation, first adjust the position of the adjusting gear 45 meshing with the driving gear 41 according to the angle between the positions where holes need to be punched on the valve surface. When adjusting, first slide the limit block 71 upward to cause the surface of the limit block 71 to bulge out from the inner surface of the limit groove 72 on the surface of the adjusting block 44, and then pull the adjusting block 44 to cause the adjusting gear 45 on the surface of the adjusting block 44 to change its position. After the position of the selected adjusting gear 45 is determined, place the valve between the fixed column 51 and the fixed rod 52 on the surface of the fixed block 3. The position of the valve on the surface of the fixed block 3 is limited by the fixed spring 54. Then the drilling machine can be started to drill holes. When changing the position for drilling holes, the control motor causes the driving rod 42 to rotate a certain number of circles. The rotation of the driving rod 42 will drive the transfer rod 43 to rotate through the synchronization component 6. The transfer rod 43 can drive the adjusting gear 45 to rotate through the locking component 8, thereby causing the driving gear 41 to rotate. The fixed block 3 can continue to drill holes after rotating a certain angle under the action of the driving gear 41.
