Abstract
Description
Technical Field
[0001] The utility model relates to a simple grinding device for a lathe. Background Art
[0002] The screw is one of the core components of the extrusion equipment. Its main function is to convert solid plastic particles or powders into stable and uniform plastic melts through the steps of conveying, compaction, compression melting, homogenization and metering, and output them to the die head and auxiliary equipment to produce products that meet the requirements. The surface processing of the screw is generally completed on a lathe. After cutting and forming, in order to improve its surface quality and appearance, as well as to enhance its function and durability, it is also necessary to grind to remove surface burrs. The existing grinding process mostly uses independent grinding equipment or manual grinding. Manual grinding has low precision, and special grinding equipment is not only costly, but also various rotation parameters and displacement parameters need to be recalculated and set according to the spiral angle of the screw fin during the grinding process, which is cumbersome to operate.

[0017] like Figure 1-3 As shown, the simple grinding device for a lathe described in the utility model includes a tool holder 2, the tool holder 2 is arranged on a carriage 1 in the lathe, and a grinding mechanism 3 is installed on the front side of the tool holder 2;
[0018] The grinding mechanism 3 includes a driving wheel 33, a driven wheel 37, and a sanding belt 34 wound between the driving wheel 33 and the driven wheel 37. The driving wheel 33 and the driven wheel 37 are mounted on the front side of the mounting positioning plate 32 through a bracket 321. The grinding surface of the sanding belt 34 faces the front side. One end of the driving wheel 33 is connected to the motor 35, and the motor 35 is mounted on the outside of the bracket 321. The rear side of the mounting positioning plate 32 is rotatably connected to the L-shaped support 31 and locked by an adjusting bolt 36. The rear end of the L-shaped support 31 is connected to the tool holder 2. The L-shaped support 31 includes a bottom plate 311 and a vertical plate 312. The bottom plate 311 is inserted into the slot 21 of the tool holder 2 and is locked in position by a locking bolt 22. The mounting positioning plate 32 is arranged on the front side of the vertical plate 312, and an integrated positioning rod 313 is provided in the middle of the front side of the vertical plate 312 (see Figure 4 ), the positioning rod 313 is inserted into the positioning hole 323 in the middle of the positioning plate 32, and waist grooves 322 are processed on both sides of the positioning hole 323 and the positioning plate 32 (see Figure 6 ), the adjusting bolt 36 is installed in the waist groove 322, and the adjusting bolt 36 is screwed into the threaded hole 315 on the vertical plate 312 after passing through the waist groove 322. A groove 314 is processed on the side of the bottom plate 311 facing the tool holder 2. The groove 314 separates the end of the bottom plate 311 to form two symmetrical plug-in parts 316 (see Figure 5 ), the plug-in portion 316 is inserted into the slots 21 on both sides of the tool holder 2.
[0019] The device utilizes existing lathe equipment and adds a grinding mechanism to the tool holder.
