Detailed ways

A kind of tire mold drilling machine as shown in Figure 1, it is provided with a frame 1, and this frame 1 comprises a base 11 and two columns 12 that are fixedly installed on the base 11, the top of two columns 12 A crossbeam 12 is provided, and one end of the crossbeam 2 is rotatably arranged on the top end of one of the columns 12 through a rotating shaft. Block 7 is locked on another column 12. When the crossbeam 2 needs to be rotated, just remove the locking block 7 and rotate along the axis of rotation, as shown in Figure 2. With the rotation, in the actual operation process, when the beam 2 is turned, the parts connected thereto (such as the cutter head 3 and the lifting drive mechanism 4) are all rotated, so that when a tire mold is processed, the beam 2 can be rotated 3. The tire mold located on the lower side can be easily removed from the workbench 6.

The frame 1 is connected with a processing head 3, and a workbench 6 is arranged below the processing head 3. The workbench 6 is rotatably arranged on the upper surface of the base 11, so that when processing tire molds, as long as the rotation workbench 6, The staff can easily process the entire tire mold without moving. The workbench 6 is also provided with a claw 61 for clamping the tire mold on the workbench 6. Usually, the claw 61 can extend the diameter of the workbench 6. Telescoping to be able to hold tire molds of different diameters. The processing head 3 is also provided with a lifting drive mechanism 4 that drives the processing head 3 to perform lifting movements. The coarse adjustment mechanism 42 and the fine adjustment mechanism 43 , and the lifting drive mechanism 4 are also provided with a bracket 41 , and the bracket 41 is fixed on the beam 2 .

The coarse adjustment mechanism 42 is composed of a rack 421 fixedly arranged on the bracket 41 and extending along the vertical direction, and a driving gear 422 rotatably arranged on the processing head 3 and meshed with the rack 421 . When the driving gear 422 is rotated, the processing head 3 can rise or fall to meet the height requirement of processing tires. The fine-tuning mechanism 43 is made up of the screw rod 431 that is rotatably arranged on the support 41 and the split nut 432 that cooperates with the screw rod 431. The split nut 432 is provided with an elastic push rod 433, and the elastic push rod 433 is far away from the clutch. One end of the nut 432 is provided with an eccentric wheel 434, and the eccentric wheel 434 is opposed to one end of the elastic push rod 433, and the elastic push rod 433 can push the split nut 432 against the screw rod 431, so that the screw rod 431 rotates It can drive the split nut 432 to go up and down.

In order to enable the processing head 3 to tilt left and right, an inclination adjustment device 5 is also arranged on it. The inclination adjustment device 5 is rotatably arranged on the bracket 41 by the fan gear 51 fixed on the processing head 3 and is connected with the fan. The adjusting gear 52 meshed with the gear 51 constitutes, and the adjusting gear 52 is rotated like this, so that the sector gear 51 will drive the processing head 3 to tilt left and right, thereby satisfying the processing needs.

The processing head 3 includes a drill bit 31 and a drill bit holder 35, wherein the drill bit 31 is arranged on the drill bit holder 35, and is generally driven by a motor to rotate. A guide rail 411 extending horizontally is disposed on the bracket 41 . The drill seat 35 is slidably disposed on the bracket 41 along the guide rail 411 . A feed rack 32 extending horizontally is fixed on the bit seat 35, and a rotatable feed gear 33 is engaged with the feed rack 32. When the feed gear 33 is rotated, the feed gear 33 promotes the feed rack 32 moves forward, so that the drill bit holder 35 slides horizontally along the guide rail 411, thereby reaching the feed requirement of the drill bit 31. In order to make the drill bit return to its original position after feeding a hole, a spring 34 is arranged between the drill bit holder 35 and the feed gear 33 .
