Description

Technical Field

[0001] This application relates to the technical field of water drilling rigs, and in particular to a water drilling rig roller seat. Background Technology

[0002] In the industrial sector, grinding and polishing machines are highly efficient and precise surface treatment equipment, widely used in various industrial sectors such as metals, electronics, optics, and ceramics. Through precise grinding and polishing processes, they improve the surface finish and precision of workpieces, making them a key tool for enhancing product quality and production efficiency.

[0003] Within the existing technological framework, Chinese patent CN105234777A discloses an advanced diamond grinding and polishing machine design. This machine features a sophisticated structure, including a robust base, a flexible sliding guide rail, a precise roller seat, and a highly efficient roller. The roller's precise positioning on the roller seat ensures both axial and radial stability while allowing for free circumferential rotation, providing a solid foundation for the precision machining of water drills. Simultaneously, the parallel guide rails on both sides of the sliding guide rail, in conjunction with internal sliding guide blocks, further enhance the flexibility and accuracy of the machining process.

[0004] However, in practical applications, diamond grinding and polishing machines face a significant technical challenge: as the machine operates continuously, the roller surface gradually heats up due to frequent friction and cutting operations. This not only affects processing quality but also shortens the service life of the rollers and even the entire machine. To address this issue, the traditional approach is to install cooling water pipes fixed above the roller base to spray cooling water and reduce the roller temperature. However, this method is particularly cumbersome in space-constrained factory environments. The installation and maintenance of cooling pipes become difficult, limiting the flexible layout and efficient operation of the production line, indicating room for improvement. Utility Model Content

[0005] The purpose of this application is to provide a water drill roller seat to solve the problem of the difficulty in installing cooling pipes in limited space in the above-mentioned related technologies.

[0006] The technical solution for a water drill roller seat provided in this application is as follows: A water drill roller base includes a base with an installation cavity for inserting a roller. Rotary grooves, communicating with the installation cavity, are formed on opposite sides of the upper side of the base, into which the rotating shafts at both ends of the roller are inserted. A locking element for limiting the rotation of the roller shaft is fixed above the rotating grooves. A cooling pipe is provided on the upper side of the base facing the installation cavity, and a water injection pipe is fixed on the outer periphery of the cooling pipe. Several water spray nozzles are provided on the side of the cooling pipe facing the installation cavity. Several drain holes for discharging cooling water are provided on the bottom side of the base at the installation cavity.

[0007] By adopting the above technical solution, when the water drill roller base is used, the roller and cooling pipe are pre-installed on the base, and the external water pipe is connected to the water injection pipe. When the water drill is running, the external water source is injected into the cooling pipe through the water injection pipe, and then sprayed from the spray nozzle onto the outer circumference of the roller. The water then flows into the installation cavity and is discharged from the drain hole. Since the cooling pipe is pre-installed and fixed, only the external pipe needs to be connected to the water injection pipe, which improves the corresponding space utilization and reduces the difficulty of subsequent pipe connection.

[0008] Optionally, the base is provided with a support member for supporting and limiting the cooling pipe. The support member includes support blocks symmetrically fixed on the base. Positioning blocks are fixed at both ends of the cooling pipe. Insertion limiting grooves are opened on the sides of the two support blocks that are close to each other.

[0009] By adopting the above technical solution, during the installation of the cooling pipe, the positioning blocks at both ends of the cooling pipe are inserted into the limiting grooves on the support block, thereby realizing the installation of the cooling pipe and facilitating subsequent maintenance and replacement of the cooling pipe.

[0010] Optionally, the positioning block has a circular cross-section and can rotate around its own axis within the limiting groove. An elastic snap-fit ​​element is provided on the outer periphery of the positioning block, and a plurality of positioning grooves for inserting the elastic snap-fit ​​element are evenly provided on the inner wall of the limiting groove.

[0011] By adopting the above technical solution, the positioning block can rotate and adjust within the limiting groove around its own axis, thereby adjusting the angle of the water spray nozzle toward the roller; when the positioning block rotates and moves by an angle, the elastic snap-fit ​​can be snapped into the corresponding positioning groove, thereby limiting and locking the cooling pipe after the rotation adjustment is completed, reducing the possibility of the cooling pipe being loose under natural conditions.

[0012] Optionally, an elastic washer is fitted on the outer periphery of the positioning block.

[0013] By adopting the above technical solution, after the cooling pipe is installed, the elastic washer is compressed, and its two opposite sides abut against the sides of the support block and the cooling pipe, thereby improving the installation stability of the cooling pipe.

[0014] Optionally, an extension is fixedly provided on the side of the support block, and the extension is fixedly connected to the locking member.

[0015] By adopting the above technical solution, due to the setting of the extension, after the locking member is installed on the base, the extension is then fixed on the locking member, thereby realizing the installation and fixation of the support block.

[0016] Optionally, the locking element includes a locking plate fixed above the rotating groove, and the locking plate has a locking notch on its side facing the rotating groove.

[0017] By adopting the above technical solution, a locking plate is used to control the rotation of the roller end shaft, and the locking notch and the rotation groove are matched to limit the rotation of the roller end shaft.

[0018] Optionally, the side of the extension facing the base abuts against the side of the locking plate away from the base. The side of the locking plate is provided with a locking screw, which passes through the coaxial through hole on the extension and the locking plate and is screwed into the screw hole on the base.

[0019] By adopting the above technical solution, the locking screw passes through the coaxial through hole in the extension and the locking plate and is screwed into the screw hole on the base, thereby enabling the simultaneous installation and fixing of the support block and the locking plate.

[0020] Optionally, an elastic protective sleeve is fixedly fitted on the outer periphery of the water injection pipe, and the outer periphery of the elastic protective sleeve is provided with anti-slip texture.

[0021] By adopting the above technical solution, when it is necessary to rotate and adjust the cooling pipe, the elastic protective sleeve on the outer circumference of the water injection pipe can be gripped tightly, and the elastic protective sleeve can also be gripped when installing the cooling pipe.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. When the water drilling rig is running, the external water source is injected into the cooling pipe through the water injection pipe, and then sprayed from the water nozzle onto the outer circumference of the roller. The water then flows into the installation cavity and is discharged from the drain hole. Since the cooling pipe is pre-installed and fixed, only the external pipe needs to be connected to the water injection pipe, which improves the corresponding space utilization and reduces the difficulty of subsequent pipe connection.

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.

[0027] Example: Reference Figure 1 and Figure 2 A water drill roller seat includes a base 1, wherein the base 1 has an installation cavity 11 for inserting the roller, and the upper side of the base 1 has two opposite sides with rotating grooves 12 for inserting the rotating shafts at both ends of the roller and communicating with the installation cavity 11, and a locking member 2 for limiting the rotation of the roller shaft is fixed above the rotating grooves 12. A cooling pipe 3 is provided on the upper side of the base 1 facing the mounting cavity 11. A water injection pipe 31 is welded and fixed on the outer periphery of the cooling pipe 3. Several water spray nozzles are provided on the side of the cooling pipe 3 facing the mounting cavity 11. Several drain holes 111 for cooling water to be discharged are opened on the bottom side of the base 1 at the mounting cavity 11. An external water source is injected into the cooling pipe 3 through the water injection pipe 31, and then sprayed from the water spray nozzles onto the outer periphery of the roller. The water then flows into the mounting cavity 11 and is discharged from the drain holes 111.

[0028] Reference Figure 2 and Figure 3 The base 1 is provided with a support member 4 for supporting and limiting the cooling pipe 3. The support member 4 includes a support block 41 symmetrically fixed on the base 1.

The two support blocks 41 are provided with insertion limiting grooves 411 on their sides that are close to each other. The positioning blocks 32 can rotate and adjust within the limiting grooves 411 around their own axis, thereby adjusting the angle of the water spray nozzle toward the roller.

[0029] Reference Figure 3 and Figure 4The positioning insert 32 is provided with an elastic snap-fit ​​5 on its outer periphery. The elastic snap-fit ​​5 includes a compression spring 51 and an arc-shaped protrusion 52. The positioning insert 32 is provided with a placement groove 321 for the compression spring 51 and the arc-shaped protrusion 52 to be placed. The compression spring 51 squeezes the arc-shaped protrusion 52, so that a part of the arc-shaped protrusion 52 protrudes from the opening of the placement groove 321. The protruding part of the arc-shaped protrusion 52 is an arc surface, and the arc length corresponding to the arc surface is a minor arc. At the same time, a number of positioning grooves 412 for the elastic snap-fit ​​5 to be inserted are evenly provided on the inner wall of the limiting groove 411. When the positioning block 32 rotates and moves, the protruding part of the arc-shaped protrusion 52 is pressed into the corresponding positioning groove 412 by the compression of the compression spring 51, thereby realizing the limiting and locking of the cooling pipe 3 after the rotation adjustment is completed, reducing the possibility of the cooling pipe 3 being loose under natural conditions.

[0030] Reference Figure 3 An elastic washer 33 is fitted on the outer periphery of the positioning insert 32; after the cooling pipe 3 is installed, the elastic washer 33 is compressed, and its two opposite sides abut against the sides of the support block 41 and the cooling pipe 3 respectively.

The side of the locking plate 21 is provided with a locking screw 22. The locking screw 22 passes through the coaxial through hole on the extension 42 and the locking plate 21 and is screwed into the screw hole on the base 1, thereby simultaneously realizing the installation and fixation of the support block 41 and the locking plate 21.

[0032] Reference Figure 6 An elastic protective sleeve 6 is fixedly fitted on the outer periphery of the water injection pipe 31, and the outer periphery of the elastic protective sleeve 6 is provided with anti-slip texture; when it is necessary to rotate and adjust the cooling pipe 3, the elastic protective sleeve 6 on the outer periphery of the water injection pipe 31 can be gripped tightly, and the elastic protective sleeve 6 can also be gripped when installing the cooling pipe 3.

[0033] The implementation principle of this application embodiment is as follows: When the water drill roller seat is used, the roller and cooling pipe 3 are installed on the base 1 in advance, and the external water pipe is connected to the water injection pipe 31. When the water drill is running, the external water source is injected into the cooling pipe 3 through the water injection pipe 31, and then sprayed from the water nozzle onto the outer circumferential surface of the roller. Then the water flows into the mounting cavity 11 and is discharged from the drain hole 111.
