[0026] This embodiment is described by taking the workpiece as a pattern block as an example. Of course, the workpiece may also be other workpieces that need to be processed with a back normal hole.

[0027] In this embodiment, the base assembly 10 serves as the basic part of the whole equipment and plays the role of bearing other components. The base assembly 10 includes a base 11, a central axis 12, a rotating arm 13 and a workbench 14, wherein the base 11 serves as the base of the whole equipment and can be installed and fixed on the platform as needed, and the central axis 12 is connected to the base 11 and extends upward. The rotating arm 13 is arranged on the central axis 12, and the rotating arm 13 is rotatable relative to the central axis 12. The base 31 is connected to the rotating arm 13. In this way, when adjusting the back normal hole facing the drilling and tapping assembly 50, the circumferential position of the height adjustment assembly 30, the lateral adjustment assembly 40, and the drilling and tapping assembly 50 relative to the pattern block can be changed by rotating the rotating arm 13, so that the height adjustment assembly 30, the lateral adjustment assembly 40, and the drilling and tapping assembly 50 can be rotatably arranged relative to the base 11, and the back normal hole to be processed can be adjusted. Preferably, a slewing support 15 is arranged between the rotating arm 13 and the central axis 12, and the slewing support 15 ensures the smoothness of the rotation between the rotating arm 13 and the central axis 12. The workbench 14 is formed with a certain area for supporting and placing workpieces such as pattern blocks, and the workbench 14 is installed and supported on the central shaft 12 by bolts and other components. Of course, the base assembly 10 is not limited to the above-mentioned arrangement, and it can also adopt other arrangements as needed.

[0028] In this embodiment, since the tread block has a certain size, the rotating arm 13 of this embodiment extends radially along the central axis 12. The end of the rotating arm 13 close to the central axis 12 is in a sleeve shape and is sleeved on the outside of the central axis 12. One or more swivel supports 15 are arranged between the inner wall of the sleeve and the outer wall of the central axis 12. The end of the rotating arm 13 away from the central axis 12 is connected to the base 31 of the height adjustment assembly 30. In this way, a certain distance is left between the drilling and tapping assembly 50 and the center line of the central axis 12, providing space for the installation of the tread block, so that it can adapt to tread blocks of different specifications and models, thereby improving adaptability.

[0029] The base assembly 10 of this embodiment further includes a tool bench 16, which is in a disc shape and is sleeved outside the central axis 12. Tools can be placed on the tool bench 16 as needed. In order to facilitate personnel to take tools, the tool bench 16 is arranged on the central axis 12 between the base 11 and the rotating arm 13 in the height direction.

[0030] In this embodiment, the support assembly 20 includes a tooling plate 21, a plurality of equal-height pads 22 and a pressing plate 23. The tooling plate 21 is of a size comparable to that of the workbench 14, and is used to install the pattern block. That is, the tooling plate 21 is supported on the workbench 14, and the pattern block is directly installed on the tooling plate 21 through the pressing plate 23. Specifically, the pattern block is placed on the tooling plate 21, and the pressing plate 23 is pressed on the edge of the pattern block. Through holes are provided on the pressing plate 23 and the tooling plate 21, and bolts are passed through the through holes. Tightening the nuts on the bolts can make the pressing plate 23 press the pattern block, thereby installing and fixing the pattern block on the tooling plate 21. Multiple pressing plates 23 can be provided as needed, and multiple positions of the pattern block are pressed to ensure the reliability of fixation. A plurality of equal-height pads 22 are provided between the workbench 14 and the tooling plate 21. The flatness of the tooling plate 21 can be adjusted by adjusting the equal-height pads 22, so that the installation parameters such as the flatness of the pattern block meet the processing requirements. Of course, the above-mentioned installation and fixing method can also be adopted in other ways.

[0031] In this embodiment, an upwardly protruding positioning shaft 141 is provided at the center of the workbench 14. Correspondingly, a positioning hole is provided at the center of the tooling plate 21. When the tooling plate 21 is placed on the workbench 14, the positioning hole docks at the positioning shaft 141, thereby positioning the tooling plate 21 to ensure accurate installation.

[0032] Preferably, when adjusting the equal height pad 22 to adjust the flatness, the flatness tolerance of the tooling plate 21 is less than or equal to 0.05 mm, so that the flatness tolerance of the workpiece mounted on the tooling plate 21 is less than or equal to 0.05 mm.

[0033] In this embodiment, the height adjustment assembly 30 further includes a pulley 35 rotatably disposed on the base 31. In this embodiment, two pulleys 35 are disposed, one is located above the counterweight 32, and the other is located above the slider 33. The rope 34 is wound around and supported on the two pulleys 35. In this way, when the counterweight 32 moves up and down, the slider 33 can be smoothly driven up and down through the two pulleys 35, making the whole process smooth and reliable. Of course, the number and position of the pulleys 35 can be adjusted as needed.

[0034] In this embodiment, the lateral adjustment assembly 40 is manually controlled, and of course, it can also be controlled by a motor. The lateral adjustment assembly 40 includes a slide 41, a slide 42 and a hand wheel 43. The slide 41 is connected to the slider 33 and moves up and down synchronously with the slider 33. The slide 41 is opened in the horizontal direction, more specifically, in the normal direction of the pattern block. The slide 42 is arranged on the slide 41 in a lateral movable manner. The drilling and tapping assembly 50 is connected to the slide 42, so that when the slide 42 slides along the slide 41, it can drive the drilling and tapping assembly 50 to approach or move away from the pattern block, so as to realize the processing of the back normal hole and the switching of the position. The hand wheel 43 is rotatably arranged on the slide 42. The slide 41 and the hand wheel 43 are both provided with meshing teeth, and the meshing teeth on the two mesh with each other. In this way, when the operator rotates the hand wheel 43, the rotation of the hand wheel 43 can drive the slide 42 to move laterally along the slide 41 through the tooth meshing, so as to realize the movement of the drilling and tapping assembly 50. The height adjustment component 30 and the lateral adjustment component 40 cooperate to adjust the height and lateral position of the drilling and tapping component 50, so that the drilling and tapping component 50 can be aligned with the back normal hole to be processed and switch positions between the back normal holes, thereby realizing the processing of a whole circle of back normal holes of the pattern block, and both are simple to operate and easy to use.

[0035] In this embodiment, the drilling and tapping assembly 50 includes a drilling and tapping main machine 51, a quick-change chuck 52 and a tap 53. The drilling and tapping main machine 51 is arranged on the slide 42 of the lateral adjustment assembly 40, and moves laterally driven by the slide 42. The quick-change chuck 52 is connected to the drilling and tapping main machine 51 by driving. The tap 53 is connected to the quick-change chuck 52, and rotates to process the back normal hole driven by the quick-change chuck 52. The drilling and tapping main machine 51 is a component that provides power, driving the tap 53 to rotate, so as to realize the drilling of the back normal hole; the quick-change chuck 52 is used to install and clamp the tap 53, and different taps 53 can be replaced for different back normal holes, and the quick-change chuck 52 can realize the rapid replacement of the tap 53, thereby improving the processing efficiency. The tap 53 rotates under the drive of the drilling and tapping main machine 51 to drill the back normal hole.

[0036] The use process of the tire mold back normal hole processing equipment of this embodiment is as follows:

[0037] When in use, fix the base 11 on the ground, use anchor bolts to fix the base 11 firmly, select the tooling plate 21 with appropriate specifications according to the actual size of the mold, fasten the pattern block on the tooling plate 21 through the pressure plate 23, and further place the connected whole on the workbench 14, and place the equal-height pad 22 between the workbench 14 and the tooling plate 21, so that the flatness of the pattern block is within the process requirements. At this time, manually adjust the height of the slider 33 through the counterweight 32, so that the height of the tap 53 on the drilling and tapping main machine 51 reaches the theoretical processing position, and start the processing of the first back normal hole to be processed on the pattern block by turning the hand wheel 43 and starting the drilling and tapping main machine 51. After completion, rotate the rotating arm 13 through the slewing support 15, and then adjust the position of the slide 42 and the drilling and tapping assembly 50 by driving the hand wheel 43 to process other back normal holes to be processed in sequence until it is finally completed.
