Description
Technical Field
[0001] The utility model relates to the technical field of drilling and tapping spindles, in particular to a ring spray structure of a drilling and tapping spindle. Background Art
[0002] A drilling and tapping spindle is a spindle used on CNC machine tools to rotate drilling and tapping tools to machine workpieces. Existing drilling and tapping spindles with ring spray systems require the ring spray inlet to be connected to multiple pipes or a separate ring spray plate. This design results in significant interference between parts, and the nozzle angle cannot be adjusted, making it unsuitable for water spray applications on machine tools. Summary of the Invention
[0003] The problem to be solved by the utility model is to provide a ring spray structure for a drilling and tapping spindle, which avoids interference between parts and can adjust the angle of the nozzle to achieve a better water spraying effect.
[0004] To solve the above technical problems, a ring-spray structure of a drilling and tapping spindle provided by the utility model is required, which includes a ring-spray sleeve and a core shaft arranged in the ring-spray sleeve. The ring-spray sleeve includes a sleeve portion and a flange portion connected to one end of the sleeve portion. One end of the core shaft is sleeved with a ring-spray front cover fixedly connected to the bottom of the flange portion. An annular water storage tank is provided on the outer periphery of the ring-spray front cover. An outer ring that closes the annular water storage tank is sleeved on the ring-spray front cover. A water inlet connected to the annular water storage tank is provided on the flange portion. The bottom of the ring-spray front cover is provided with nozzle mounting holes connected to the annular water storage tank in an annular array, and a universal nozzle is installed on the nozzle mounting hole.
[0005] Preferably, annular accommodating grooves are provided on both sides of the outer periphery of the ring spray front cover, and a sealing ring is sleeved on the annular accommodating groove to abut against the inner wall of the outer ring.
[0006] Preferably, an annular limiting platform is provided on the outer peripheral edge of the bottom of the ring spray front cover, and the outer ring is clamped between the top of the annular limiting platform and the bottom of the flange part.
[0007] The beneficial effects of the present invention are as follows: the present invention provides a ring spray structure for a drilling and tapping spindle, a water pipe is connected to the water inlet, and the universal nozzles are distributed in a ring array at the bottom of the ring spray front cover, and water is supplied to the ring water storage tank through the water pipe. When the tool installed on the spindle processes the workpiece, a ring-shaped water spray effect can be formed at the processing position of the workpiece. The spray direction of each universal nozzle can be adjusted according to the processing requirements to form different water spray angles and water spray ranges. Only a water pipe needs to be connected to the flange part to avoid interference between parts and there is no need to make a separate ring spray plate. The structure of the spindle is simplified, and disassembly and maintenance are more convenient, which is worthy of popularization and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model provides an annular spray structure for a drilling and tapping spindle, comprising an annular spray sleeve 1 and a core shaft 2 arranged in the annular spray sleeve 1. The annular spray sleeve 1 comprises a sleeve portion 10 and a flange portion 11 connected to one end of the sleeve portion 10. One end of the core shaft 2 is sleeved with an annular spray front cover 3 fixedly connected to the bottom of the flange portion 11. An annular water storage tank 30 is provided on the outer periphery of the annular spray front cover 3. An outer ring 4 that closes the annular water storage tank 30 is sleeved on the annular spray front cover 3. A water inlet 110 connected to the annular water storage tank 30 is provided on the flange portion 11. Nozzle mounting holes 111 connected to the annular water storage tank 30 are distributed in an annular array on the bottom of the annular spray front cover 3. A universal nozzle 5 is mounted on the nozzle mounting hole 111.
