Description

Technical Field

[0001] The utility model relates to the technical field of automotive air-conditioning pulley processing, in particular to a grooving device for processing automotive air-conditioning pulleys. Background Technique

[0002] Grooving of automotive air-conditioning pulleys refers to the grooves processed on the air-conditioning compressor drive pulleys in the automotive air-conditioning system for accommodating and guiding the operation of the drive belt. The design and condition of these grooves are crucial for the effective transmission between the belt and the pulley.

[0003] However, when the existing automotive air-conditioning pulleys are processed and grooved, the waste chips generated in the grooving area and the discharged cutting fluid are mixed with each other, and are affected by the components rotating at high speed in the grooving area, resulting in the waste materials splashing out, which affects the operation of the operator on the CNC lathe and seriously pollutes the grooving production and processing area.

[0004] Therefore, a grooving device for processing automotive air-conditioning pulleys has now been developed, which can cover the grooving area of the pulley to prevent the chips and cutting fluid from splashing randomly during processing. Content of the Utility Model

The tool is slidably connected to the upper side of the front part of the CNC lathe, the cutting fluid spray pipe is connected to the upper left part of the CNC lathe, and the splash-proof mechanism is arranged on the upper side of the middle part of the CNC lathe.

[0007] In one embodiment, a control system is arranged on the upper side of the right front part of the CNC lathe.

[0008] In one embodiment, the splash-proof mechanism includes a support block, a protective cover, a sliding rod and an adjusting screw.

Rotating the adjusting screw controls the left and right movement of the protective cover by means of the thread. When the protective cover moves to the left, it covers the grooving area of the pulley to prevent chips from splashing.

[0009] In one embodiment, a knob is arranged on the right side of the adjusting screw.

[0010] In one embodiment, a discharging mechanism is further included. The discharging mechanism includes a connecting block, a scraping strip and a reciprocating lead screw, and a motor. The left side of the rear part of the protective cover is connected with the connecting block. The reciprocating lead screw is rotatably connected to the connecting block. The scraping strip is threadedly connected to the left part of the reciprocating lead screw. The scraping strip is slidably connected to the inner side of the protective cover.
