There are many types of precision parts, and various specifications of precision castings are used in machine tool equipment. Therefore, there is a particular need for a wear-resistant precision casting for machine tools.

[0003] However, existing precision castings for machine tools have certain drawbacks in use. Because precision castings do not have a certain level of protection, the friction generated between the contact surfaces during long-term use will cause a certain degree of wear and affect the service life. Utility Model Content

[0004] The purpose of this utility model is to provide a wear-resistant precision casting for machine tools, in order to solve the problem mentioned in the background art that the existing precision castings for machine tools have certain drawbacks in use. Because precision castings do not have certain protection, the friction generated between the contact surfaces during long-term use will cause a certain degree of wear, affecting the service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant precision casting for machine tools, comprising a mounting base plate, a lower retaining shaft connected to the surface of the mounting base plate, a limit retaining ring connected to the surface of the mounting base plate, a connecting rotating rod connected to the surface of the lower retaining shaft, a wear-resistant mechanism provided on one side of the surface of the connecting rotating rod, a mounting mechanism provided on one side of the surface of the connecting rotating rod, an upper retaining shaft connected to one side of the surface of the connecting rotating rod, a lower half-cylinder connected to one side of the surface of the connecting rotating rod, an upper half-cylinder connected to one side of the surface of the connecting rotating rod, a movable plate connected to one side of the surface of the lower half-cylinder, and a limit groove formed on one side of the surface of the movable plate;

[0007] Preferably, the connecting rod is fitted inside the slot, the rubber pad is sleeved on the surface of the connecting rod, and the ceramic coating is aluminum oxide.

[0008] Preferably, one side of the surface of the roller is fitted inside the slot, and one side of the surface of the roller is in contact with the inner wall of the lower clamping shaft.

[0009] Preferably, the rollers are arranged in six groups, and the rollers are distributed in a ring with equal spacing, and the nano-coating is silicon dioxide.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a wear-resistant precision casting for machine tools, including a mounting base plate 1, a lower retaining shaft 2 connected to the surface of the mounting base plate 1, a limit retaining ring 3 connected to the surface of the mounting base plate 1, a connecting rotating rod 4 connected to the surface of the lower retaining shaft 2, a wear-resistant mechanism 5 provided on one side of the surface of the connecting rotating rod 4, a mounting mechanism 6 provided on one side of the surface of the connecting rotating rod 4, an upper retaining shaft 7 connected to one side of the surface of the connecting rotating rod 4, a lower half-cylinder 8 connected to one side of the surface of the connecting rotating rod 4, an upper half-cylinder 9 connected to one side of the surface of the connecting rotating rod 4, a movable plate 10 connected to one side of the surface of the lower half-cylinder 8, and a limit groove 11 formed on one side of the surface of the movable plate 10;

[0022] The wear-resistant mechanism 5 includes a ceramic coating 501, a nano coating 502, a groove 503, a connecting rod 504, a rubber pad 505, a locking groove 506, and a roller 507. The surface of the mounting base plate 1 is coated with a ceramic coating 501, the surface of the lower locking shaft 2 is coated with a nano coating 502, a groove 503 is formed on one side of the surface of the connecting rod 4, a connecting rod 504 is fitted onto one side of the surface of the connecting rod 4, a rubber pad 505 is fitted onto one side of the surface of the connecting rod 4, a locking groove 506 is formed on the surface of the lower half-cylinder 8, and one end of the connecting rod 504 is connected to the roller 507. During use, the ceramic coating 501 on the surface of the mounting base plate 1 effectively reduces the friction generated when the movable plate 10 contacts it, resulting in good overall wear resistance and ensuring smooth movement of the movable plate 10 on its surface. When the user operates the movable plate 10, the surface of the connecting rod 504... The roller 507 can roll flexibly within the locking groove 506 on the surface of the lower half-cylinder 8. This rolling process greatly reduces the wear between the lower half-cylinder 8 and the upper half-cylinder 9 and the connecting rod 4, extending the service life of related components. If the user applies too much force when moving the movable plate 10, the rubber pad 505 on the inside of the locking groove 506 will be compressed by the connecting rod 504 on the surface of the roller 507. In this way, rigid contact between the roller 507 and the lower half-cylinder 8 and the upper half-cylinder 9 is cleverly avoided, preventing damage to the components due to excessive impact. At the same time, during the rotation of the connecting rod 4, the nano-coating 502 between the lower locking shaft 2 and the upper locking shaft 7 has a high degree of smoothness, which significantly reduces the friction between the connecting rod 4 and the lower locking shaft 2 and the upper locking shaft 7, further helping the entire wear-resistant mechanism 5 to function and effectively extending the service life of the precision casting.

[0023] Furthermore, the connecting rod 504 is fitted inside the slot 503, and the rubber pad 505 is sleeved on the surface of the connecting rod 504. The ceramic coating 501 is aluminum oxide. With the setting of the rubber pad 505, when the user moves the movable plate 10 too violently during use, it will be compressed by the connecting rod 504 on the surface of the roller 507, thereby avoiding rigid contact between the roller 507 and the lower half-cylinder 8 and the upper half-cylinder 9, playing a buffering and protective role, and preventing damage to related components due to excessive rigid collision.

[0024] Furthermore, one side of the surface of the roller 507 is fitted inside the slot 506, and one side of the surface of the roller 507 is in contact with the inner wall of the lower clamping shaft 2. With the setting of the roller 507, when the movable plate 10 moves during use, the roller 507 can roll in the slot 506, thereby reducing the wear between the lower half-cylinder 8 and the upper half-cylinder 9 and the connecting rotating rod 4. By replacing possible sliding friction or rigid collision with rolling friction, the relevant components are effectively protected and their service life is extended.

[0025] Furthermore, six sets of rollers 507 are provided, and the rollers 507 are distributed in a ring with equal spacing. The nano-coating 502 is made of silicon dioxide. With the setting of the nano-coating 502, the nano-coating 502, which is made of silicon dioxide, has high smoothness during use. With its high smoothness, it can significantly reduce the friction between the connecting rod 4 and the lower clamping shaft 2 and the upper clamping shaft 7, and reduce the wear caused by friction between the parts.

[0026] Furthermore, the mounting mechanism 6 includes a first threaded groove 601, a fixing bolt 602, a first through hole 603, a first bolt 604, a second threaded groove 605, a second through hole 606, a second bolt 607, and an internal threaded block 608. The lower retaining shaft 2 has a first threaded groove 601 on one side of its surface, and a fixing bolt 602 is connected to one end of the connecting rod 4. The upper retaining shaft 7 has a first through hole 603 on one side of its surface, and a first bolt 604 is threaded through one side of the upper retaining shaft 7. The lower half-cylinder 8 has a second threaded groove 605 on one side of its surface, and a second through hole 606 is threaded through one side of the upper half-cylinder 9. A second bolt 607 is threaded through one side of the upper half-cylinder 9. One end of the fixing bolt 602 is threadedly connected to an internal threaded block 608. The mounting mechanism 6 is constructed by connecting the first threaded groove 601, the fixing bolt 602, the first through hole 603, the first bolt 604, the second threaded groove 605, the second through hole 606, the second bolt 607, and the internal threaded block 608. When using the threaded block 608, during the assembly of the precision casting, firstly, the movable plate 10 is placed on the surface of the mounting base plate 1. Then, the lower half-cylinder 8 on one side of the movable plate 10 is horizontally aligned with the lower retaining shaft 2 on the surface of the mounting base plate 1. Subsequently, the connecting rod 4 is embedded into the surface of the lower retaining shaft 2 and the lower half-cylinder 8. The upper retaining shaft 7 and the upper half-cylinder 9 are placed horizontally on the other side of the connecting rod 4, and the first through hole 603 and the second through hole 606 on their surfaces are horizontally aligned with the first thread groove 601 and the second thread groove 605, respectively. Then, the first bolt 604 is used to thread through the first through hole 603 and connect to the first thread groove 601. At the same time, the second bolt 607 is used to thread through the second through hole 606 and connect to the second thread groove 605. At this time, the internal threaded block 608 is used to connect around the thread on the surface of the fixing bolt 602, thereby installing the movable plate 10 onto the surface of the mounting base plate 1 and completing the assembly of the precision casting.

[0027] Furthermore, one end of the first bolt 604 is threadedly connected to the first threaded groove 601, and the size of the first bolt 604 matches that of the first through hole 603. With the setting of the first bolt 604, in use, after the first end of the first bolt 604 passes through the first through hole 603 of the upper clamping shaft 7 and is threadedly connected to the first threaded groove 601 of the lower clamping shaft 2, the lower clamping shaft 2 and the upper clamping shaft 7 can be firmly fixed together.

[0028] Furthermore, one end of the second bolt 607 is threadedly connected to the second threaded groove 605, and the size of the second bolt 607 matches that of the second through hole 606. With the setting of the second bolt 607, in use, after the second bolt 607 passes through the second through hole 606 of the upper half cylinder 9 and is threadedly connected to the second threaded groove 605 of the lower half cylinder 8, the upper half cylinder 9 and the lower half cylinder 8 can be firmly fixed together.

[0029] Working principle: First, when assembling the precision casting, the movable plate 10 is placed on the surface of the mounting base plate 1. Then, the lower half-cylinder 8 on one side of the movable plate 10 is horizontally aligned with the lower retaining shaft 2 on the surface of the mounting base plate 1. Subsequently, the connecting rod 4 is embedded into the surface of the lower retaining shaft 2 and the lower half-cylinder 8. The upper retaining shaft 7 and the upper half-cylinder 9 are then horizontally placed on the other side of the connecting rod 4, and the first through hole 603 and the second through hole 606 on their surfaces are horizontally aligned with the first thread groove 601 and the second thread groove 605, respectively. Then, the first bolt 604 is used to penetrate through. The first through hole 603 is threadedly connected to the first threaded groove 601. Simultaneously, a second bolt 607 is threaded through the second through hole 606 and into the second threaded groove 605. Then, an internal threaded block 608 is used to connect around the threads on the surface of the fixing bolt 602, thereby installing the movable plate 10 onto the surface of the mounting base plate 1, completing the assembly of the precision casting. After assembly, the user needs to install the precision casting onto the machine tool to be used via the mounting base plate 1 at its bottom end, and through the movable plate 10, the limiting retaining ring 3, and the limiting groove 11. The rollers 507 on the surface of the connecting rod 504 can roll flexibly within the locking groove 506 on the surface of the lower half-cylinder 8 when the user operates the movable plate 10 after the entire precision casting is installed. This rolling process greatly reduces the wear between the lower half-cylinder 8 and the upper half-cylinder 9 and the connecting rotating rod 4, and extends the service life of the relevant components. If the user applies too much force when moving the movable plate 10, the rubber pad 505 on the inner side of the locking groove 506 will be pressed against the surface of the roller 507. The connecting rod 504 is compressed under pressure, which cleverly avoids rigid contact between the roller 507 and the lower half-cylinder 8 and the upper half-cylinder 9, preventing damage to the components due to excessive impact. At the same time, during the rotation of the connecting rod 4, the nano-coating 502 between the lower clamping shaft 2 and the upper clamping shaft 7 has a high degree of smoothness, which significantly reduces the friction between the connecting rod 4 and the lower clamping shaft 2 and the upper clamping shaft 7, further helping the entire wear-resistant mechanism 5 to function and effectively extending the service life of the precision casting.
