Description

Technical Field

[0001] The invention relates to the technical field of cutter head production, and in particular to a split cutter head production process. Background Art

[0002] The fast drilling split cutter head (referred to as split cutter head) is a tool designed to improve drilling efficiency and reliability. An inclined wedge eccentric clamping mechanism is usually designed between the cutter head and the tool bar. The inclined wedge part realizes axial anti-slip, and the eccentric clamping part realizes interference fit and cutter head positioning to ensure the stability and reliability of the cutter head during high-speed drilling.

[0003] The production process of the split cutter head involves a post-processing process, which involves post-processing such as sandblasting and chip groove polishing of the cutter head. The purpose of sandblasting the cutter head is to passivate the cutting edge and remove irregular burrs. When sandblasting, a sandblasting machine is used for blasting. During the sandblasting process, a plurality of cutter heads are first installed in a circular array on the rotating mechanism of the rotating disk. When two adjacent cutter heads on the rotating disk rotate to a position close to the sandblasting device, the liftable sandblasting device sandblasts the rotatable cutter head. However, the installation and removal of the cutter head during the sandblasting process is as follows: before the start of sandblasting, the cutter heads are installed one by one on the rotating mechanism of the rotating disk in coordination with the rotation of the rotating disk. After the sandblasting is completed, the cutter heads are removed one by one in coordination with the rotation of the rotating disk. At this time, the installation and removal of the cutter head causes the sandblasting machine to need a longer interval between the two sandblasting operations, thereby affecting the sandblasting efficiency. Summary of the invention

When the air inlet 561 of the air inlet pipe 56 is connected with the first outlet 611, the air inlet pipe 56 covers the second outlet 612, and the linkage assembly 8 drives the valve handle to rotate so that the three-way valve 58 is connected with the filter recovery box 7; when the air inlet 561 of the air inlet pipe 56 is connected with the second outlet 612, the air inlet pipe 56 covers the first outlet 611, and the linkage assembly 8 drives the valve handle to rotate so that the three-way valve 58 is connected with the connecting pipe 55.

[0034] like Figures 4 to 6 As shown, the linkage assembly 8 includes a rack 81 disposed at the bottom of the collecting hopper 6, and a gear 82 disposed on the valve handle of the three-way valve 58 and having a center line that coincides with the rotation axis of the valve handle, and the rack 81 and the gear 82 are meshed. When the three-way valve 58 moves along with the blower 54, the rack 81 and the gear 82 control the rotation of the valve handle. At the same time, when the air inlet 561 of the air inlet pipe 56 moves back and forth within the range between the first outlet 611 and the second outlet 612, the rack 81 and the gear 82 are meshed, and the two are separated when the range is exceeded.

[0035] like Figures 4 to 6As shown, a movable lifting mechanism 9 is arranged between the bottom of the filter recovery box 7 and the body 1, and the movable lifting mechanism 9 includes a movable seat 91, a plurality of universal wheels 92 arranged at the bottom of the movable seat 91, a lifting plate 93 which is lifted and arranged on the movable seat 91 and embedded in the bottom of the filter recovery box 7, and a guide component 94 which is arranged on the body 1 and first causes the lifting plate 93 to move upward and then maintain horizontal movement during the movement of the filter recovery box 7 in the direction close to the body 1; within the moving range of the blower 54 connecting the first outlet 611 and the second outlet 612, the filter recovery box 7 remains in a horizontal state; a receiving pipe 59 which is arranged obliquely downward toward the front side of the body 1 is arranged on the joint of the three-way valve 58 connecting the filter recovery box 7, and the inclination angle of the receiving pipe 59 is the same as the angle of the oblique upward movement of the lifting plate 93, and an air inlet plug-in pipe 71 which is plugged into the receiving pipe 59 during the oblique upward movement is arranged on the top of the filter recovery box 7. When the blower 54 moves toward the front side of the body 1, the air inlet 561 of the air inlet pipe 56 is connected with the second outlet 612 and the first outlet 611 in sequence. When the blower 54 moves forward to the extreme state, the air inlet 561 of the air inlet pipe 56 passes through the first outlet 611, and the receiving pipe 59 is aligned with the air inlet plug-in pipe 71 which moves obliquely upward.

[0036] like Figure 4 and Figure 5 As shown, the guide assembly 94 includes two brackets 941, inclined guide rails 942 symmetrically arranged on the two brackets 941, and linear guide rails 943 symmetrically arranged on the two brackets 941 and respectively connected to the inclined guide rails 942. The bottom of the lifting plate 93 is used to abut against the inclined guide rails 942 and the linear guide rails 943. At the same time, a plurality of square tubes 931 arranged to be lifted and lowered on the moving seat 91 are arranged at the bottom of the lifting plate 93, and a handle 95 is arranged on the front side of the moving seat 91.

[0037] Implementation effect: part of the turntable device 2 is located inside the hood 4 and part of it is located outside the hood 4. After the sandblasting device 3 sandblasts the cutter head that is to be close to the workstation, the rotation of the turntable device 2 cooperates with the lifting and lowering of the sealing door 41, and the cutter head after sandblasting moves to the part outside the hood 4 as the turntable device 2 rotates. At this time, during the sandblasting process of the cutter head located inside the hood 4, it is convenient to remove the cutter head that has been sandblasted outside the hood 4 and install the unprocessed cutter head, thereby improving the efficiency of sandblasting. At the same time, during the sandblasting process, part of the abrasive will fall on the upper surface of the turntable device 2. By arranging a blower mechanism 5 at the front bottom of the sealing door 41, the abrasive attached to the upper surface of the turntable device 2 located outside the hood 4 is blown off, and collected by the collecting hopper 6, thereby preventing the abrasive from falling on the ground during the rotation of the turntable device 2.

[0038] When the sealing door 41 moves downward to the limit state, the pressing block 46 is first pressed against the rubber pad 45 for sealing, and then the rubber sealing strip 47 is pressed against the rotating disk 21 of the turntable device 2 for sealing. The sealing sleeve 44 on the groove 43 can seal the edge of the rotating disk 21 of the turntable device 2, thereby ensuring the sealing of the equipment during operation.

[0039] By setting up the blower 54, the connecting pipe 55, the air supply pipe 51 and the plurality of blowing nozzles 52, the abrasive on the part of the rotating disk 21 of the turntable device 2 outside the closed door can be blown down into the collecting hopper 6, and at the same time, the air in the collecting hopper 6 can be extracted during the operation of the blower 54, so that the air flows into the collecting hopper 6 from the collecting hopper 6 and the cavity around the plate of the turntable device 2, so that some fine abrasives will be carried into the collecting hopper 6 by the air flow during the blowing down process and filtered by the filter cartridge 53, so as to avoid the situation that the fine abrasives are blown out. Because the sealing door 41 involves lifting movement, the hose 552 included in the connecting pipe 551 can prevent interference with the lifting movement of the sealing door 41, and the setting of the hanging ring 553 can prevent the hose 552 from sagging.

[0040] By setting the sliding plate 62 and the driving cylinder 63, the blower 54 can be driven to move left and right; when the air inlet 561 of the air inlet pipe 56 is connected to the first outlet 611, the air inlet pipe 56 covers the second outlet 612, and the linkage component 8 drives the valve handle to rotate so that the three-way valve 58 is connected to the filter recovery box 7, so that the abrasive in the collecting hopper 6 is transported to the filter recovery box 7; when the air inlet 561 of the air inlet pipe 56 is connected to the second outlet 612, the air inlet pipe 56 covers the first outlet 611, and the linkage component 8 drives the valve handle to rotate so that the three-way valve 58 is connected to the connecting pipe 55, and the blower 54 realizes the function of supplying air to the connecting pipe 55. By setting the linkage component 8, the connection between the three-way valve 58 and the connecting pipe 55 and the three-way valve 58 and the filter recovery box 7 can be automatically switched, which is convenient for the blower 54 to switch between the two functions of blowing and recovering abrasive.

[0041] The filter recovery box 7 is mainly used for recovering abrasives. At this time, the abrasives in the filter recovery box 7 need to be recycled. At this time, when the blower 54 moves forward to the limit state, the air inlet plug-in tube 71 of the filter recovery box 7 is plugged into the receiving tube 59 during the tilted upward movement of the lifting plate 93, so that the filter recovery box 7 and the three-way valve 58 are connected, and within the moving range of the blower 54 connecting the first outlet 611 and the second outlet 612, the filter recovery box 7 remains in a horizontal state, thereby ensuring that the filter recovery box 7 and the three-way valve 58 are always in a connected state. When the abrasives in the filter recovery box 7 need to be recovered, the blower 54 moves forward to the limit state, and the movable lifting mechanism 9 continues to move forward, so that the air inlet plug-in tube 71 and the receiving tube 59 of the filter recovery box 7 are separated, thereby achieving the purpose of conveniently recovering the abrasives after disassembly and movement. The guide assembly 94 includes a bracket 941, an inclined guide rail 942 and a linear guide rail 943, so that the lifting plate 93 is first tilted upward and then kept horizontally moving during the movement of the lifting plate 93 along the inclined guide rail 942 and the linear guide rail 943.
