Description

Technical Field

[0001] This application relates to the technical field of tapping equipment, and in particular to a fully automatic drilling and tapping equipment for the production of expansion blocks. Background Technology

[0002] Air shafts are core components of winding and unwinding equipment for films, paper, and fabrics, and are widely used in industries such as packaging, printing, and plastics processing. As a key expansion and stress-bearing component of the air shaft, the processing precision and structural strength of the expansion block directly determine the expansion and contraction stability, load-bearing capacity, and service life of the air shaft.

[0003] In related technologies, the forming process of expansion blocks requires two core precision machining processes: drilling and tapping. Drilling creates assembly holes, and tapping creates matching threads to meet the needs of subsequent assembly, fixing, and positioning. In the industry, drilling and tapping of expansion blocks generally employs a separate, independent processing equipment mode, with the drilling and tapping equipment located at separate, independent workstations without a linked processing structure.

[0004] Regarding the aforementioned technologies, in batch processing, after a workpiece is processed by a single machine, multiple auxiliary processes such as station turnover, secondary loading, positioning and clamping, and unloading and transfer need to be completed manually or by transfer equipment. The overall processing flow is cumbersome and the process connections are poor. At the same time, multiple loading and unloading, and repeated positioning and clamping not only significantly increase the intensity of manual labor and the downtime of equipment, greatly reducing the overall processing efficiency, but also easily cause positioning deviations, resulting in processing defects such as misalignment of drilling and tapping, inconsistent thread accuracy, etc., causing inconsistent processing accuracy of batch workpieces and a high scrap rate. Summary of the Invention

[0005] To address the above issues, this application provides a fully automated drilling and tapping device for the production of expansion blocks.

[0006] This application provides a fully automatic drilling and tapping device for the production of expansion blocks, which adopts the following technical solution: A fully automatic drilling and tapping device for producing expansion blocks includes a frame. A rotating platform and a central worktable are coaxially mounted on the frame. The central worktable is located in the middle of the rotating platform, and the rotating platform can rotate relative to the central worktable. The frame has loading stations, drilling stations, tapping stations, and unloading stations evenly arranged sequentially along the circumference of the rotating platform. Each station is equipped with a corresponding loading mechanism, drilling mechanism, tapping mechanism, and unloading mechanism. The rotating platform has several mounting stations for placing expansion blocks to be processed evenly spaced along its circumference. The frame is equipped with a drive device and a transmission assembly. The drive device drives the rotating platform to rotate intermittently through the transmission assembly.

[0007] By adopting the above technical solution, the rotating platform rotates intermittently under the action of the drive device, which drives the expansion blocks on the installation station to flow sequentially to the feeding, drilling, tapping and unloading stations, realizing multi-station synchronous continuous operation, replacing manual operation, and greatly improving the processing efficiency and automation level of expansion block drilling and tapping. At the same time, the circumferential layout structure is compact, with high space utilization, and the processing of each station does not interfere with each other, ensuring processing stability.

[0008] Preferably, the feeding mechanism includes a vibratory feeder, a feeding channel, a first cylinder, a first pneumatic module, and a second pneumatic module. A support is fixedly connected to the frame, and the feeding channel is fixedly mounted on the support. The feeding port of the feeding channel communicates with the discharge port of the vibratory feeder, and the feeding port of the feeding channel is set corresponding to the feeding station. A guide channel perpendicularly communicating with the feeding channel is fixedly connected to the support. The first cylinder is fixed to the support, and a push plate is fixedly connected to the piston rod of the first cylinder, and the push plate is slidably mounted. Inside the material guiding channel, the push plate has a slot for engaging the expansion block on one side facing the material guiding channel; a first column is fixed to the end of the material guiding channel away from the first cylinder, the first pneumatic module is horizontally fixed to the first column, the cylinder body of the second pneumatic module is vertically fixed to the slider of the first pneumatic module, and a suction pipe for adsorbing the expansion block is fixed to the bottom end of the slider of the second pneumatic module. The suction pipe is connected to a negative pressure air source, and the first pneumatic module is used to drive the second pneumatic module to move horizontally to the installation position.

[0009] By adopting the above technical solution, the vibratory feeder automatically sorts and feeds the blocks. The expansion blocks enter the guide channel through the feeding channel. The first cylinder drives the push plate to push the expansion blocks to the designated position. The second pneumatic module drives the suction pipe to move down and absorb the expansion blocks. Then, the first pneumatic module moves the expansion blocks horizontally to the top of the installation station to complete the feeding. The entire process of feeding, picking up and unloading is automated without manual intervention. The feeding is accurate and efficient, and it is suitable for batch production needs.

[0010] Preferably, a positioning block is fixedly assembled inside the material guide channel at one end near the first pneumatic module.

[0011] By adopting the above technical solution, the positioning block accurately limits the expansion block pushed to the material picking position, avoids the expansion block from deviating, ensures that the suction pipe can accurately pick up the expansion block, improves the feeding positioning accuracy, and ensures the accuracy of subsequent processing positions.

[0012] Preferably, a clamping mechanism is provided on the central worktable at the positions corresponding to the drilling station and the tapping station. The clamping mechanism is used to clamp the expansion block placed on the installation station.

[0013] By adopting the above technical solution, during drilling and tapping operations, the clamping mechanism firmly presses the expansion block into the installation position to prevent displacement or shaking of the expansion block during processing, ensuring the positional accuracy and processing quality of drilling and tapping, and avoiding defective products.

[0014] Preferably, the clamping mechanism includes a mounting frame, on which a clamping cylinder is vertically fixedly connected. A pressure block is rotatably connected to the end of the piston rod of the clamping cylinder, and the middle part of the pressure block is hinged to the side wall of the mounting frame.

[0015] By adopting the above technical solution, the piston rod of the pressing cylinder extends and retracts, driving the pressing block to rotate around the hinge point, thereby realizing the pressing and releasing of the expansion block. The lever-type pressing structure has stable force, uniform pressing force, and fast operation response.

[0016] Preferably, the pressure block has a strip groove on the side facing the installation station, and the groove opening is directly opposite the machining hole of the expansion block.

[0017] By adopting the above technical solution, the strip groove avoids the drilling and tapping positions of the expansion block, prevents the pressure block from blocking the processing area, and does not affect the clamping effect. This ensures that the drilling and tapping mechanisms can smoothly process the designated positions of the expansion block and prevents the pressure block from interfering with the processing action.

[0018] Preferably, the central workbench is provided with several flushing mechanisms, which are respectively arranged between the drilling station, the tapping station, and the loading and unloading stations, for flushing out the bulging blocks during the processing and the empty installation stations.

[0019] By adopting the above technical solution, the iron filings generated during drilling and tapping can be promptly flushed and cleaned by the flushing mechanism, preventing iron filings from adhering to the surface of the expansion block or accumulating at the installation station, ensuring the cleanliness of the expansion block's machining surface, and preventing iron filings from affecting the subsequent machining accuracy and normal equipment operation.

[0020] Preferably, each of the flushing mechanisms includes a flushing nozzle, a water pump, and a water outlet pipe. The water outlet of each flushing nozzle faces the installation position. An annular water tank is provided on the frame, located directly below the rotating platform. A drain outlet is provided on the bottom of the annular water tank, and a sealing plug is provided at the drain outlet. An open receiving groove is fixedly connected to the upper end of the side wall of the annular water tank. The rotating platform is rotatably disposed in the receiving groove. A water outlet is provided at the bottom of the receiving groove. A water inlet is provided on the side wall of the annular water tank. The water pump is fixed to the outside of the frame, and the water outlet of the water pump is connected to the water outlet pipe. All flushing nozzles are connected to the pipe wall of the water outlet pipe.

[0021] By adopting the above technical solution, the water pump provides flushing power, the flushing nozzle continuously sprays water to flush, and the sewage and iron filings flow into the annular water tank through the outlet of the receiving tank for unified collection and discharge, avoiding the sewage and iron filings from scattering and polluting the equipment and working environment. The sealing plug facilitates regular cleaning of debris in the water tank, making maintenance convenient.

[0022] Preferably, the bottom of the rotating platform is provided with a brush that contacts the bottom of the receiving groove.

[0023] By adopting the above technical solution, when the rotating platform rotates, the brush simultaneously cleans the bottom of the receiving tank, sweeping the iron filings and debris remaining at the bottom of the tank to the water outlet. This, combined with the flushing mechanism, further improves the cleaning effect and prevents the accumulation of debris from affecting the smooth rotation of the rotating platform.

[0024] Preferably, the unloading mechanism includes a third pneumatic module and a fourth pneumatic module. A second column is vertically fixed to the frame. The third pneumatic module is horizontally fixed to the upper end of the second column. The cylinder of the fourth pneumatic module is vertically fixed to the slider of the third pneumatic module. A pneumatic gripper is provided at the lower end of the slider of the fourth pneumatic module. A discharge channel is inclinedly fixed to the second column. The discharge port of the discharge channel is located at the unloading station. A receiving frame is provided at the lower end of the discharge channel.

[0025] By adopting the above technical solution, the processed expansion block is transferred to the unloading station. The fourth pneumatic module drives the pneumatic gripper to move down and clamp the expansion block. The third pneumatic module drives it to move horizontally above the discharge channel. The pneumatic gripper releases, and the expansion block slides down through the discharge channel into the receiving frame, realizing automated unloading and finished product collection with smooth connection, completing the fully automated processing.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By using a rotating platform and a multi-station synchronous operation structure, the entire process of feeding, drilling, tapping and unloading of the expansion block is automated and continuous, which greatly improves processing efficiency and reduces labor costs. At the same time, the circumferential layout structure is compact and has high processing accuracy and consistency. 2. By setting up a clamping mechanism, the positioning of the expansion block is ensured to be stable during drilling and tapping, thereby improving machining accuracy; 3. With the addition of a flushing mechanism, iron filings generated during drilling and tapping can be promptly flushed away, preventing them from adhering to the surface of the expansion block or accumulating at the installation station. This ensures the cleanliness of the expansion block's machining surface and prevents iron filings from affecting subsequent machining accuracy and the normal operation of the equipment.
