Description

Technical Field

[0001] This utility model relates to the technical field of tool-changing structures, specifically a belt-driven spindle tool-changing structure. Background Technology

[0002] The existing belt-driven spindle tool-changing structure has a pull rod installed in the center hole of the spindle. A connecting nut, a tool-changing bracket, and a tool-changing seat are installed on the outer end of the pull rod protruding from the spindle. The tool-changing bracket and tool-changing seat ensure reliable installation of the pull rod. A guide nut is fitted inside the pull rod corresponding to the inside of the spindle. During actual assembly, a central water outlet structure needs to be installed inside the pull rod. Current assembly methods require installing a spray nozzle adapter at the rear end of the pull rod, drilling holes on the outer periphery of the pull rod, and then connecting the water outlet end of the spray nozzle adapter. This necessitates ensuring reliable installation alignment during assembly, making the existing belt-driven spindle tool-changing structure complex and leading to complicated assembly. Therefore, a relatively simple spindle tool-changing structure is urgently needed. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a belt-driven spindle tool-changing structure, which is simple and quick to assemble, reduces assembly time, and improves equipment assembly efficiency.

[0004] A belt-driven spindle tool changing structure, characterized in that it comprises: mandrel; The pull rod includes a spindle through end, a guide ring, and a cutter holder, which are integral structures. Butterfly-shaped shrapnel; And the sensor wheel; The spindle has a central hole at its center. The spindle end of the pull rod passes through the central hole and is fitted with a butterfly-shaped spring. The rear end of the pull rod has a radially protruding guide ring corresponding to the rear end position of the central hole. The outer ring surface of the guide ring is covered with at least one sealing ring. The sealing ring is arranged close to the inner wall of the central hole of the spindle. The guide ring is used to keep the concentricity of the pull rod consistent. The induction wheel is fixedly mounted on the rear ring surface of the spindle. The rear end of the pull rod also has a protruding cutter seat. The radial center of the pull rod has an axially penetrating central water outlet hole.

[0005] Its further features are: The mounting ring of the induction wheel is fitted around the outer periphery of the self-lubricating bushing, and the fastener passes through the ring of the induction wheel and is fixed to the rear end ring surface of the spindle. The front part of the cutting tool holder includes a guide protrusion ring and a limiting part. The outer diameter of the guide protrusion ring is slightly smaller than the inner diameter of the central hole, and the outer diameter of the limiting part is larger than the inner diameter of the central hole. The guide protrusion ring is used to move the cutting tool working rod relative to the spindle, and the limiting part is used to limit the forward movement of the rod. The rear center of the cutter holder has an internally threaded hole, which is used to connect to an external rotary joint. The rotary joint is used to introduce high-pressure water into the internally threaded hole. The internally threaded hole is connected to the central water outlet hole, thereby achieving the water outlet function. The mandrel through end is fitted with a gasket corresponding to the front end of the guide ring, the gasket is used to isolate the butterfly gasket and the guide ring so that the two do not wear.

[0006] By adopting the solution of this utility model, the original guide nut is designed to be integrated into the guide ring of the pull rod, and the original connecting nut, cutter bracket and cutter seat that needed to be assembled separately are designed to be integrated into the pull rod seat body at the rear end of the pull rod. The central water outlet mechanism is designed as a central water outlet hole, which makes the assembly of the entire spindle cutter structure simple and quick, reduces the assembly time and improves the assembly efficiency of the equipment.

[0007] Figure 1 This is a cross-sectional view of the present invention; The names corresponding to the serial numbers in the diagram are as follows: Mandrel 10, center hole 11, pull rod 20, mandrel through end 21, guide ring 22, cutter seat 23, guide protrusion ring 231, limiting part 232, internal concave threaded hole 24, center water outlet hole 25, butterfly spring 30, induction wheel 40, fastener 50, gasket 60, sealing ring 70, self-lubricating bushing 80. Detailed Implementation

[0008] A belt-driven spindle tool changing structure, see Figure 1 It includes a spindle 10, a pull rod 20, a butterfly spring 30, and a sensing wheel 40; The pull rod 20 includes a spindle through end 21, a guide ring portion 22, and a cutter holder 23; The spindle 10 has a central hole 11. The spindle end 21 of the pull rod 20 passes through the central hole 11 and is fitted with a butterfly-shaped spring 30. The rear end of the pull rod 20 is provided with a radially protruding guide ring 22 corresponding to the rear end position of the central hole 11. Two sealing rings 70 are arranged at intervals on the outer ring surface of the guide ring 22. The sealing rings 70 are arranged in close contact with the inner wall of the central hole 11 of the spindle 10. The guide ring 22 is used to keep the concentricity of the pull rod 20 and the spindle 10 consistent. The rear end ring surface of the spindle 10 is fixedly mounted with a sensing wheel 40. The rear end of the pull rod 20 is also provided with a protruding cutter seat 23. The radial center of the pull rod 20 is provided with an axially penetrating central water outlet 25.

[0009] In practice, the mounting ring of the sensing wheel 40 is fitted around the outer periphery of the self-lubricating bushing 80, and the fastener 50 is fixed to the rear end ring surface of the spindle 10 after passing through the ring of the sensing wheel 40. The front part of the cutter holder 23 includes a guide protrusion ring 231 and a limiting part 232. The outer diameter of the guide protrusion ring 231 is slightly smaller than the inner diameter of the central hole 11, and the outer diameter of the limiting part 232 is larger than the inner diameter of the central hole 11. The guide protrusion ring 231 is used to move the cutter working pull rod 20 relative to the spindle 10, and the limiting part 232 is used to limit the forward movement of the pull rod 20. The rear center of the cutter holder 23 is provided with an internally threaded hole 24. The internally threaded hole 24 is used to connect to an external rotary joint (not shown in the figure, which is an existing mature structure). The rotary joint is used to introduce high-pressure water flow into the internally threaded hole 26. The internally threaded hole 24 is connected to the central water outlet hole 25, thereby achieving the water outlet function. A washer 60 is fixedly fitted at the front end of the spindle through end 21 corresponding to the front end of the guide ring 22. The washer 60 isolates the butterfly washer 30 and the guide ring 22 so that the two do not wear.

[0010] The original guide nut was designed to be integrated into the guide ring of the pull rod. The connecting nut, cutter bracket and cutter holder that originally needed to be assembled separately were designed to be integrated into the pull rod seat at the rear end of the pull rod. The central water outlet mechanism was designed as a central water outlet hole. This makes the assembly of the entire spindle cutter structure simple and quick, reduces assembly time and improves the assembly efficiency of the equipment.
