Description

Technical Field

[0001] This invention relates to the field of grinding machine slide rail technology, and in particular to a double V-type slide rail system for grinding machines. Background Technology

[0002] Machine tool motion guides come in various structures, including V-flat, double V, dovetail, and rolling guide structures, each with its own advantages and disadvantages. Among them, the guiding mechanism composed of two sets of paired V-shaped guides is widely used in high-precision feed systems of CNC machine tools and other scenarios requiring guidance and positioning due to its unique contact stability and force distribution. The double V structure is either integrally cast with the moving parts or separately assembled and fixed, with dimensional and positional accuracy entirely guaranteed by machining. The installation of separately assembled V-shaped guides on mechanical equipment generally involves combining the positioning surface of the guide body with the mounting surface on the mechanical equipment, and then fixing it to the mechanical equipment with bolts through the threaded holes on the guide body.

[0003] Currently, in the V-shaped guide rail structure of all mechanical equipment, the position between the two V-shaped guide rails is completely fixed. The fit between the positioning surface and the V-shaped groove of the guide rail requires high shape tolerance control, which places particularly high demands on the precision of the processing equipment. This results in high processing difficulty, high processing cost, and difficulty in guaranteeing quality and accuracy. Summary of the Invention

[0004] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a double V-type slide rail system for grinding machines to solve the existing problems.

[0006] To achieve the above objectives, the technical solution of the present invention is: a double V-shaped slide rail system for a grinding machine, comprising a machining bed, V-shaped grooves provided on both sides of the top of the machining bed, a worktable mounted on the top of the machining bed, the worktable being connected by V-shaped guide rails matching the V-shaped grooves, wherein one side of the V-shaped guide rail is fixedly installed to the worktable, and an adjustment component is installed between the other side of the V-shaped guide rail and the worktable; a connecting frame is provided in the middle of the machining bed, the connecting frame being slidably connected to the machining bed, the top of the connecting frame being connected to the worktable, and the connecting frame driving the worktable to slide on the V-shaped grooves via a first threaded rod.

[0007] In some embodiments, the adjustment assembly includes a connecting plate, with first threaded holes at both ends of the top of the connecting plate, and mounting holes at positions corresponding to the first threaded holes of the V-shaped guide rail. A rotating shaft is mounted in the mounting hole, and a second threaded rod is mounted on each rotating shaft. A slot is mounted on the top of the second threaded rod.

[0008] In some embodiments, an adjusting plate is installed on the connecting plate, the adjusting plate has multiple adjusting grooves, and limiting grooves are provided on both sides of the adjusting grooves. A pushing block is installed in each adjusting groove, the top of the pushing block is inclined, a third threaded rod is installed on the pushing block, one end of the third threaded rod passes through the adjusting groove, and the third threaded rod is threadedly connected to the adjusting groove. An adjusting block is also installed in the adjusting groove, the bottom of the adjusting block has a matching inclined surface at a position opposite to the pushing block, and a limiting rod is provided at a position opposite to the limiting groove of the adjusting block.

[0009] In some embodiments, a limiting plate is installed on the third threaded rod at a position outside the adjusting groove, the surface of the limiting plate is provided with a rotating groove, and a positioning plate is installed between the limiting plate and the adjusting plate.

[0010] In some embodiments, the adjusting plate and the second threaded rod are provided with matching connecting grooves at their relative positions, the second threaded rod is inserted into the connecting grooves, and the adjusting plate and the connecting plate are fixedly connected by bolts.

[0011] In some embodiments, the connecting plate is provided with a plurality of first marking grooves along the edge of the first threaded hole, and the top of the second threaded rod is provided with a second marking groove.

[0012] In some embodiments, a rotating component is installed between the connecting frame and the worktable. The rotating component includes a rotating platform, which is mounted on the connecting frame. A rotating groove is provided on the top of the rotating platform, and the rotating groove is rotatably connected to the worktable. The two sides of the top of the rotating platform are inclined downwards.

[0013] In some embodiments, the top of both ends of the adjustment plate is provided with connecting rods, which are inserted into the corresponding holes of the workbench and fixedly connected with nuts.

[0014] In some embodiments, the bottom of the V-shaped guide rail is equipped with multiple sliding arc-shaped protrusions.

[0015] In some embodiments, the positioning plate is provided with a positioning groove that matches the limiting plate.

[0016] By adopting the above technical solution, the beneficial effects of the present invention are: This invention involves mounting the worktable in a V-shaped groove via a V-shaped guide rail. Then, a first threaded rod drives a motor to move the worktable back and forth on a machining bed for processing. After installation, one side of the worktable can be finely adjusted and raised using an adjustment component. Because the V-shaped groove is inclined, the movable end will automatically align with the V-shaped surface. If there are gaps at the top and bottom, the movable end will move laterally under gravity or a slight external force while fitting against the upper and lower contact surfaces of the V-shaped groove, which is equivalent to completing the vertical accuracy calibration. This eliminates the need to machine a corresponding V-shaped guide rail for fine tolerance machining.

[0017] The adjustment component can be adjusted according to installation requirements using the second threaded rod. Specifically, the second threaded rod is rotated, causing the connecting plate to move up and down. This lifts one side of the worktable, allowing the V-shaped guide rail to fit more closely to the V-shaped groove for precise positioning and lateral movement. After adjustment, the worktable is locked with bolts to complete the up-and-down adjustment of the movable end, ensuring a closer fit between the V-shaped guide rail and the V-shaped groove on the fixed side. This eliminates the need for re-machining the guide rail and groove for a more precise fit.

[0018] By installing an adjustment plate on the connecting plate, and then setting multiple adjustment slots on the adjustment plate, a push block and an adjustment block are set in the adjustment slots. The push block is moved by rotating the third threaded rod, so that the inclined surface of the push block and the inclined surface of the adjustment block cooperate to push the adjustment block to move upward. At the same time, the limit rod can effectively limit the up and down movement of the adjustment block, and then let the adjustment block push its worktable upward. At the same time, the adjustment blocks at various positions can be adjusted according to the actual situation to make the V-shaped guide rail fit better.

[0019] The connecting groove is designed so that when the adjusting plate and the connecting plate are connected, the protruding second threaded rod can be inserted into the connecting groove, allowing the connecting plate and the adjusting plate to fit together and then be fixed in place by the connecting plate. At the same time, during operation, the second threaded rod will not rotate and cause the connecting plate to move. Therefore, it is not necessary to disassemble the adjusting plate and the worktable for a large adjustment. Then, by matching the first and second marking grooves, the rotation angle and the distance of movement of the connecting plate can be determined. This allows for more precise adjustment. After that, the worktable can be installed, and fine adjustments can be made at various positions by using the adjusting plate to make the guide rail and slide groove fit better.

[0020] The workbench can be moved upwards by adjusting the adjustment plate and the connecting plate. In order to ensure that the workbench can be moved by the connecting frame, the V-shaped guide rails on both sides can be positioned and precisely fitted by setting a rotating table on the connecting frame and the inclined surfaces on both sides of the rotating table.

[0033] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0034] Reference Figure 1-2 This invention provides a double V-shaped slide rail system for a grinding machine, including a machining bed 1. V-shaped grooves 11 are provided on both sides of the top of the machining bed 1. A worktable 2 is mounted on the top of the machining bed 1. The worktable 2 is connected to a V-shaped guide rail 3 that matches the V-shaped grooves 11. One side of the V-shaped guide rail 3 is fixedly installed to the worktable 2, and an adjustment component 4 is installed between the other side of the V-shaped guide rail 3 and the worktable 2. A connecting frame 12 is provided in the middle of the machining bed 1, and the connecting frame 12 is slidably connected to the machining bed 1. The top of the connecting frame 12 is connected to the worktable 2. The connecting frame 12 drives the worktable 2 to slide on the V-shaped grooves 11 via a first threaded rod 13.

[0035] Specifically, the worktable 2 is installed in the V-shaped groove 11 via the V-shaped guide rail 3. Then, the first threaded rod 13 drives the worktable 2 to move back and forth on the machining bed 1 via a motor for processing. After installation, one side of the worktable 2 can be finely adjusted and raised by the adjustment component 4. Because the V-shaped groove 11 is inclined, the movable end will automatically align with the V-shaped surface. If there is a gap between the top and bottom, the movable end will move laterally under gravity or slight external force while fitting the upper and lower contact surfaces of the V-shaped groove, which is equivalent to completing the accuracy calibration in the upper and lower directions. In this way, it is not necessary to process the corresponding V-shaped guide rail 3 for fine tolerance processing.

[0036] Reference Figure 1-4 According to some embodiments of the present invention, optionally, the adjusting component 4 includes a connecting plate 46, both ends of the top of the connecting plate 46 are provided with first threaded holes 42, the V-shaped guide rail 3 is provided with mounting holes 43 corresponding to the first threaded holes 42, the mounting holes 43 are provided with rotating shafts 44, and each rotating shaft 44 is provided with a second threaded rod 45, the top of the second threaded rod 45 is provided with a slot 451.

[0037] Adjustment component 4 can be adjusted according to installation requirements by inserting a tool into slot 451 to adjust the second threaded rod 45. Specifically, the second threaded rod 45 is rotated to move the connecting plate 46 up and down, thereby lifting one side of the worktable 2 so that the V-shaped guide rail 3 fits more closely to the V-shaped slide groove 11 for better positioning and lateral movement. After adjustment, the worktable 2 is locked with bolts to complete the up and down adjustment of the movable end, so that the V-shaped guide rail 3 and V-shaped slide groove 11 on the fixed side fit more closely together, without the need for re-processing the guide rail and slide groove for a more precise fit.

[0038] Reference Figure 4 According to some embodiments of the present invention, optionally, an adjusting plate 41 is installed on the connecting plate 46, the adjusting plate 41 is provided with a plurality of adjusting grooves 411, and limiting grooves 412 are provided on both sides of the adjusting grooves 411. A pushing block 413 is installed in each adjusting groove 411. The top of the pushing block 413 is inclined. A third threaded rod 414 is installed on the pushing block 413. One end of the third threaded rod 414 passes through the adjusting groove 411 and is threadedly connected to the adjusting groove 411. An adjusting block 415 is also installed in the adjusting groove 411. The bottom of the adjusting block 415 is provided with a matching inclined surface relative to the pushing block 413. A limiting rod 416 is provided relative to the limiting groove 412 of the adjusting block 415.

[0039] By installing an adjustment plate 41 on the connecting plate 46, and then setting multiple adjustment slots 411 on the adjustment plate 41, a push block 413 and an adjustment block 415 are set in the adjustment slots 411. By rotating the third threaded rod 414, the push block 413 is moved, so that the inclined surface of the push block 413 and the inclined surface of the adjustment block 415 cooperate to push the adjustment block 415 upward. At the same time, the limit rod 416 can effectively limit the up and down movement of the adjustment block 415, and then let the adjustment block 415 push its worktable 2 upward. At the same time, the adjustment blocks 415 at each position can be adjusted according to the actual situation to make the V-shaped guide rail 3 fit better.

[0040] Reference Figure 1-5 According to some embodiments of the present invention, optionally, a limiting plate 417 is installed on the third threaded rod 414 at a position outside the adjusting groove 411. The limiting plate 417 has a rotating groove 418 on its surface. A positioning plate 419 is installed between the limiting plate 417 and the adjusting plate 41. The positioning plate 419 has a positioning groove 4191 that matches the limiting plate 417.

[0041] Because the third threaded rod 414 will move out of the adjusting plate 41 during rotation, the distance moved can be used to use the matching positioning plate 419 to lock the gap between the limiting plate 417 and the adjusting plate 41, so as to avoid the push plate from moving during operation. At the same time, the positioning groove 4191 can be set on the positioning plate 419 to better limit the limiting plate 417.

[0042] Reference Figure 4 According to some embodiments of the present invention, optionally, the adjusting plate 41 and the second threaded rod 45 are provided with matching connecting grooves 47 at opposite positions, the second threaded rod 45 is inserted into the connecting grooves 47, and the adjusting plate 41 and the connecting plate 46 are fixedly connected by bolts. The connecting plate 46 is provided with a plurality of first marking grooves 461 along the edge of the first threaded hole 42, and the top of the second threaded rod 45 is provided with a second marking groove 462.

[0043] The connection groove 47 is designed so that when the adjusting plate 41 and the connecting plate 46 are connected, the protruding second threaded rod 45 can be inserted into the connection groove 47, allowing the connecting plate 46 and the adjusting plate 41 to fit together and be further fixed by the connecting plate 46. At the same time, during the operation, the second threaded rod 45 will not rotate and cause the connecting plate 46 to move. Therefore, it is not necessary to disassemble the adjusting plate 41 and the worktable 2 for a large adjustment. Then, by matching the first marking groove 461 and the second marking groove 462, the rotation angle and the distance of movement of the connecting plate 46 can be determined. This allows for more precise adjustment. After that, the worktable 2 can be installed, and fine adjustments can be made at various positions by cooperating with the adjusting plate 41 to make the guide rail and the slide groove fit together better.

[0044] Reference Figure 1-2 According to some embodiments of the present invention, optionally, a rotating component 5 is installed between the connecting frame 12 and the worktable 2. The rotating component 5 includes a rotating platform 51, which is mounted on the connecting frame 12. A rotating groove 52 is provided on the top of the rotating platform 51, and the rotating groove 52 is rotatably connected to the worktable 2. The top two sides of the rotating platform 51 are inclined downwards. By adjusting the adjusting plate 41 and the connecting plate 46, one side of the worktable 2 can be moved upwards. In order to ensure that the worktable 2 can be moved by the connecting frame 12, the rotating platform 51 on the connecting frame 12 and the inclined surfaces on both sides of the rotating platform 51 can be used to adjust and move left and right, so that the V-shaped guide rails 3 on both sides can be positioned well and accurately fit at the angle.

[0045] Reference Figure 1-2According to some embodiments of the present invention, optionally, the top of both ends of the adjusting plate 41 is provided with connecting rods 48, which are inserted into the corresponding holes of the workbench 2 and fixedly connected with nuts. This facilitates the tightening and loosening of the nuts, allowing for quick installation and separation of the workbench 2 and the adjusting plate 41, while also enabling good adjustment of the tightness during the adjustment process.

[0046] Reference Figure 2-3 According to some embodiments of the present invention, optionally, a plurality of sliding arc-shaped protrusions 31 are installed on the bottom of each V-shaped guide rail 3. Providing a plurality of sliding arc-shaped protrusions 31 on the bottom of the V-shaped guide rail 3 can reduce friction and allow the V-shaped guide rail 3 to slide better when in better contact.
