Description

[0002] Anchor connector is a device used to connect anchors with other structural parts. It is usually used in civil engineering, mining, tunnel construction and underground engineering. Both ends of the existing anchor connectors need to be tapped with internal threads using processing equipment to connect the anchors with other structures.

The hollow disk 65 then drives the tool changing ring 63 to rotate around the tool holder disk 62 through the branch pipe 610 and the hollow sleeve 611 to switch the tap bit 7. In this way, after each connector body 4 is processed, it is switched in sequence to ensure that each tap bit 7 has enough time to cool and recover.

[0055] Specifically, in the process of the feed assembly 2 driving the two symmetrical tap heads 7 to perform internal thread processing on the two ends of the connector body 4, the gear four 85 on the tap head 7 moves to engage with the gear three 84, and then the driving motor four 83 drives the driving shaft 82 to drive the gear three 84 to rotate, driving the tap head 7 to rotate and feed toward the connector body 4, and at the same time completes the processing of the internal threads at both ends of the connector body 4.

[0060] For further example 2, please refer to Figure 3 to Figure 4 As shown:

[0061] The loading assembly 3 includes a support frame 31, which is fixedly installed in the middle of the base 1. A vertical hydraulic telescopic rod 32 is arranged on the top of the support frame 31, and an upper pressure plate 33 is fixedly installed on the telescopic end of the hydraulic telescopic rod 32. A rotating frame 34 is vertically fixed on the support frame 31. The end of the rotating frame 34 away from the support frame 31 is rotatably connected to a switching roller 35. A plurality of bearing plates 36 are evenly distributed on the outer surface of the switching roller 35. Side clamping rings 37 are symmetrically and slidably inserted at both ends of the bearing plates 36 in the length direction. A spring 38 is arranged between the side clamping ring 37 and the bearing plates 36. A gear ring 39 is fixedly sleeved on one side of the switching roller 35. A driving motor 2 310 is arranged on the rotating frame 34. A gear 311 is fixedly connected to the output end of the driving motor 310, and the gear ring 39 is meshed with the gear 311.

[0062] Specifically, the side clamping ring 37 can be used to center and clamp the connector body 4 through the spring 1 38, and then the upper pressure plate 33 can be driven down by the hydraulic telescopic rod 32 to clamp and position the connector body 4 to be processed to prevent the connector body 4 from rotating. After the processing is completed, the gear 1 311 is driven to rotate by the driving motor 2 310, and the meshing gear ring 1 39 can be engaged to drive the switching roller 35 to rotate, so that the connector body 4 to be processed is rotated to the bottom of the upper pressure plate 33, the processed connector body 4 is turned out, and the unprocessed connector body 4 is disassembled and replaced. In combination with the feed assembly 2, the tool changing assembly 6, the tap head 7 and the rotating drive assembly 8, high-frequency continuous processing can be achieved.

[0064] For further example 3, please refer to Figures 6 to 8 As shown:

[0065] It also includes a liquid supply component 9 for inputting cooling lubricating liquid into the connector body 4, and the liquid supply component 9 includes a liquid supply pump 91, and the liquid supply pump 91 is fixedly installed on the top of the bracket 2 64, and the input end of the liquid supply pump 91 is connected to the cooling lubricating liquid storage container through a connecting pipe 1 92, and the output end of the liquid supply pump 91 is rotatably connected to the hollow disk 65.

[0067] Specifically, when the tap bit 7 and the connector body 4 are in contact and processing begins, the liquid supply pump 91 pumps the cooling lubricating liquid in the container into the hollow disk 65 through the connecting pipe 92, and opens the switch valve 93 corresponding to the tap bit 7 in use, so that the cooling lubricating liquid passes through the branch pipe 610 and the hollow sleeve 611 in sequence, and is rotated and sprayed from the end of the liquid supply pipe 94 toward the inner wall of the connector body 4, so as to cool and lubricate the contact surface between the connector body 4 and the tap bit 7, and cool and lubricate from the inside of the connector body 4, so as to make full use of the cooling lubricating liquid and reduce waste.

[0068] In the process of opening the switch valve 93, the switch valve 93 corresponding to the tap head 7 that has just been processed can be kept open for a period of time, so that the lubricating coolant can still flow through the tap head 7 that has just been processed, so as to keep the tap head 7 cooled and the cooling recovery efficiency of the tap head 7 accelerated, thereby enabling the tap head 7 to switch processing at a higher frequency.

[0069] For further example 4, please refer to Figures 8 to 10 As shown:

The chip removal pump 103 is fixedly connected to the top cover 104, and a screen 106 is provided in the screening cylinder 105.

[0071] Specifically, during the cooling and lubrication process, the waste chips mixed with the cooling and lubricating liquid generated in the connector body 4 can be pumped out through the chip removal pipeline 101 and the connecting pipe 102 by the chip removal pump 103, and then screened and filtered out by the screen 106, so that the cooling and lubricating liquid can be recycled.

[0072] Furthermore, the chip removal pump 103 can be driven forward and reversely during the above process, driving the cooling lubricating fluid in the chip removal pipe 101 and the connecting pipe 102 to flow forward and reversely, impacting between the connector body 4 and the tap head 7, so as to crush the cut waste chips and pump them out, while also playing a role in preventing blockage.

[0076] When in use, the side clamp ring 37 can be used to center and clamp the connector body 4 through the spring 38, and then the upper pressure plate 33 is driven down by the hydraulic telescopic rod 32 to clamp and position the connector body 4 to be processed. Then, the double-threaded rod 21 is driven to rotate by the driving motor 22, and the two moving blocks 23 are driven to move toward each other in the base 1. Then, the gear four 85 on the tap head 7 moves to mesh with the gear three 84, and the driving shaft 82 is driven by the driving motor four 83 to drive the gear three 84 to rotate, thereby completing the processing of the internal threads at both ends of the connector body 4.

[0077] After one processing is completed, the gear one 311 is driven to rotate by driving motor two 310, and the meshing gear ring one 39 can drive the switching roller 35 to rotate, so that the connector body 4 to be processed is rotated to the bottom of the upper pressure plate 33, the processed connector body 4 is turned out, and the unprocessed connector body 4 is disassembled and replaced. At the same time, the gear two 68 is driven to rotate by driving motor three 67, and the hollow disk 65 drives the tool changing ring 63 to rotate around the tool holder disk 62 through the branch pipe 610 and the hollow sleeve 611 to switch the tap head 7 for the next processing.
