AI Technical Summary
When cutting with existing diamond wire cutting machines, the surface of the spool is easily contaminated with cutting powder that mixes with water to form a mud shell, making it difficult to pull the spool out of the base.
The design employs a combination of hydraulic cylinders, disc springs, and bolts. The hydraulic cylinders lift the movable seat, increasing the space in the cylindrical groove to allow the spool to pass smoothly, while the disc springs assist in resetting. Combined with intercepting bars and striking rods, it prevents mud from contaminating the base surface.
This allows for flexible passage of the spool and cleaning of the base, preventing mud from contaminating the screw holes on the base and improving the ease of operation and cutting accuracy.

Abstract
Description
Technical Field
[0001] This utility model relates to a base for a diamond cutting machine, and more particularly to a roller spindle base for a diamond cutting machine used in the field of diamond cutting. Background Technology
[0002] A diamond wire cutting machine is a high-efficiency and precise cutting tool. Its working principle involves a high-speed rotating and reciprocating wire spool driving a diamond wire in a reciprocating motion. The diamond wire is tensioned by two tensioning rollers (spring or pneumatic), and two guide rollers are added to ensure cutting accuracy and surface shape. The machine automatically feeds the worktable towards the diamond wire control console, or controls the diamond wire control console to feed towards the worktable, causing grinding between the diamond wire and the workpiece to create a cut.
[0003] Chinese utility model patent CN216732461U discloses a vibration-resistant diamond wire cutting machine tool, including a base, a cutting motor mounted on the base, a main winding shaft facing forward on the cutting motor, a middle winding shaft mounted on the base on the same side as the main winding shaft, a tensioning slider that slides left and right inside the base, a positioning hole on the side of the base where the middle winding shaft is mounted, a limit block installed in the positioning hole, one end of the limit block engaging with the tensioning slider through the positioning hole, a connecting plate connected to the tensioning slider, and a lower winding shaft mounted on the connecting plate on the same side as the middle winding shaft. This utility model's vibration-resistant diamond wire cutting machine tool reduces vibration, improves cutting accuracy, and avoids diamond wire breakage.
[0004] Existing diamond wire cutting machines inevitably pick up powder generated during cutting. This powder mixes with the cooling water used during cutting, causing a sludge crust to form on the spool surface, making it difficult to pull out the spool. Utility Model Content
[0005] In view of the above-mentioned prior art, the technical problem to be solved by this utility model is how to improve the base of the wire cutting machine so that the spool can pass flexibly through the base.
[0006] To solve the above problems, this utility model provides a roller spindle base for a diamond cutting machine, including a base base with two symmetrically arranged inner cavities inside. The bottom wall of the inner cavity is fixed with a bracket by bolts. A hydraulic cylinder is installed on the top of the bracket. The power end of the hydraulic cylinder passes through the top of the base base. A movable seat is arranged on the top of the base base. The movable seat and the base base are respectively provided with cylindrical grooves of the same radius. A bolt is installed through the interior of the movable seat. The bolt includes a threaded part and a smooth part located above the threaded part. The smooth part passes through the interior of the movable seat. The threaded part is threadedly connected to the base base. A disc spring is installed on the top of the movable seat and sleeved on the outside of the smooth part. The power end of the hydraulic cylinder is connected to the bottom surface of the movable seat. The two output ends of the hydraulic cylinder are located in the middle of the four bolts.
[0007] In the roller spindle base of the diamond cutting machine, the movable seat can be lifted autonomously by the hydraulic cylinder, disc spring, bolts and movable seat. This increases the space of the cylindrical groove, allowing the spool to pass through more smoothly. The movable seat is also assisted in autonomously resetting under the action of the disc spring.
[0008] As a further improvement of this application, the length of the smooth part is greater than the thickness of the movable seat, and the top of the disc spring is in close contact with the bottom of the nut of the bolt.
[0009] As a further improvement of this application, the two inner cavities are arranged symmetrically about the cylindrical groove, and the two inner cavities are located on both sides of the cylindrical groove.
[0010] As a further improvement of this application, a rubber pad is installed at the bottom of the disc spring, and the bottom of the rubber pad is fixedly connected to the bottom surface of the movable seat. The rubber pad has a through hole with a diameter larger than that of the smooth part.
[0011] As another improvement of this application, the top of the base has two symmetrically arranged insertion slots, and the bottom of the movable seat is equipped with an intercepting bar that matches the insertion slots, and the height of the intercepting bar is greater than the displacement value of the hydraulic cylinder power end when it is working.
[0012] As a further improvement to this application, two symmetrically arranged striking units are installed at the top of the movable seat. Each striking unit includes a drive motor fixedly installed on the top surface of the movable seat, and the drive motor is signal-connected to a hydraulic cylinder. The output end of the drive motor is connected to a long rod, and the surface of the long rod is connected to a plurality of striking rods arranged along the axial direction, and the cross-section of the striking rods is L-shaped.
[0013] In summary, through the cooperation of hydraulic cylinders, disc springs, bolts, and movable seats, the movable seats can be raised autonomously by the lifting of the hydraulic cylinders, thereby increasing the space of the cylindrical groove and allowing the spool to pass through more smoothly. Under the action of the disc springs, the movable seats can be autonomously reset. In addition, with the help of intercepting bars and striking rods, the crust-like mud on the surface of the spool can be broken down by striking, achieving dual assistance and preventing dirt on the surface of the spool from contaminating the screw holes on the surface of the base through the gap between the base and the movable seats when the movable seats move upward.

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.
[0024] First implementation method:
[0025] Figures 1-3A roller spindle base for a diamond cutting machine is shown, comprising a base 1, with two symmetrically arranged inner cavities 2 inside the base 1. The bottom wall of the inner cavity 2 is fixed with a bracket by bolts, and a hydraulic cylinder 10 is installed on the top of the bracket. The power end of the hydraulic cylinder 10 passes through the top of the base 1. A movable seat 5 is arranged on the top of the base 1, and cylindrical grooves of the same radius are respectively provided inside the movable seat 5 and the base 1. Bolts 4 are installed through the movable seat 5, and bolts 4 include a threaded part 42 and a smooth part 41 located above the threaded part 42. The smooth part 41 passes through the interior of the movable seat 5, and the threaded part 42 is threadedly connected to the base 1. A disc spring 3 is installed on the top of the movable seat 5 and sleeved on the outside of the smooth part 41. The power end of the hydraulic cylinder 10 is connected to the bottom surface of the movable seat 5, and the two output ends of the hydraulic cylinder 10 are located in the middle of the four bolts 4.
[0026] The length of the smooth part 41 is greater than the thickness of the movable seat 5, and the top of the disc spring 3 is in contact with the bottom of the nut of the bolt part 4.
[0027] The two inner cavities 2 are arranged symmetrically about the cylindrical groove, and the two inner cavities 2 are located on both sides of the cylindrical groove.
[0028] A rubber pad is installed at the bottom of the disc spring 3, and the bottom of the rubber pad is fixedly connected to the bottom surface of the movable seat 5. The rubber pad has a through hole with a diameter larger than that of the smooth part 41.
[0029] Specifically, during operation, the spool enters and exits through the cylindrical groove. If the spool has difficulty passing smoothly through the cylindrical groove due to slurry (a mixture of diamond powder and cooling water that dries and forms a shell structure on the spool surface after a period of time) produced during diamond cutting, the hydraulic cylinder 10 is activated to move the power end upward, thereby causing the movable seat 5 to move upward (e.g., ...). Figure 4 As shown in the figure, the space in the cylindrical groove is increased at this time, which can help the spool pass through smoothly.
[0030] During the process of increasing the space of the cylindrical groove, since the threaded part 42 is threadedly connected to the base 1, the bolt part 4 is equivalent to being fixedly connected to the base 1. When the movable seat 5 moves along the surface of the smooth part 41, it will squeeze the disc spring 3, causing the disc spring 3 to be compressed. Then, when the power end of the hydraulic cylinder 10 retracts and resets, under the action of the disc spring 3, the movable seat 5 re-fits to the surface of the base 1.
[0031] In the above process, the length of the smooth part 41 is greater than the thickness of the movable seat 5, so that the smooth part 41 exposed on the surface of the movable seat 5 has space for the disc spring 3 to be sleeved.
[0032] In addition, the installation of the rubber pad ensures that the disc spring 3 makes flexible contact during compression, rather than rigid contact caused by direct contact between the disc spring 3 and the movable seat 5. This avoids wear caused by rigid compression of the disc spring 3 and ensures the service life of the disc spring 3.
[0033] Second implementation method:
[0034] Figures 5-6 The base 1 has two symmetrically arranged insertion slots 9 on its top. The bottom of the movable seat 5 is equipped with an intercepting bar 8 that matches the insertion slots 9, and the height of the intercepting bar 8 is greater than the displacement value of the hydraulic cylinder 10 when the power end is working.
[0035] Two symmetrically arranged striking units are installed at the top of the movable seat 5. The striking unit includes a drive motor 6 fixedly installed on the top surface of the movable seat 5, and the drive motor 6 is connected to the hydraulic cylinder 10. The output end of the drive motor 6 is connected to a long rod, and the surface of the long rod is connected to multiple striking rods 7 arranged along the axial direction, and the cross section of the striking rods 7 is L-shaped.
[0036] Unlike the first embodiment, this embodiment mainly targets the mud and other structures on the surface of the spool, and prevents dirt on the spool surface from entering the screw hole area on the surface of the base 1 through the gap when the movable seat 5 moves upward.
[0037] Specifically, when the movable seat 5 moves upward, the intercepting strip 8 moves upward simultaneously. Since the height of the intercepting strip 8 is greater than the effective displacement of the movable seat 5, the intercepting strip 8 can still seal the gap formed between the movable seat 5 and the base 1 when the movable seat 5 moves upward, thereby preventing dirt on the surface of the spool from contaminating the screw holes on the surface of the base 1 through the gap generated when the movable seat 5 moves upward.
[0038] When hydraulic cylinder 10 is started (that is, when the spool surface is too thick due to the slurry buildup, preventing it from passing smoothly through the cylindrical groove), drive motor 6 is started, driving the striking rod 7 to repeatedly rotate in small forward and reverse directions. This knocks and breaks down the shell on the surface of the spool entering and exiting the cylindrical groove, thus helping the spool to pass smoothly through the groove (e.g., ...). Figure 7 (As shown).
[0039] In summary, this application utilizes the hydraulic cylinder 10, disc spring 3, bolt 4, and movable seat 5 to achieve autonomous lifting of the movable seat 5 by lifting the hydraulic cylinder 10. This increases the space of the cylindrical groove, allowing the spool to pass through more smoothly. Under the action of the disc spring 3, the movable seat 5 is assisted in autonomous resetting. In addition, the intercepting bar 8 and the striking rod 7 are used to break up the crust-like mud on the surface of the spool, achieving dual assistance and preventing dirt on the surface of the spool from contaminating the screw holes on the surface of the base 1 through the gap between the base 1 and the movable seat 5 when the movable seat 5 moves upward.
[0040] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
