Description

Technical Field

[0001] This utility model relates to the field of machine tool accessories technology, specifically to an adjustment device for a machine tool linear guideway. Background Technology

[0002] Linear guides, also known as linear guides, are devices that support, fix, and guide moving devices or equipment and reduce their friction. Machine tools are machines that manufacture machinery and equipment, and linear guides are important components that affect whether the feed of output parts can proceed smoothly.

[0003] A search revealed a utility model patent with Chinese patent publication number CN209925428U, which discloses an adaptive linear slide rail, including a linear slide rail base, on which a linear slide rail is disposed. The linear slide rail is disposed on both sides of the linear slide rail base, and a plurality of sliders are disposed on the linear slide rail base. The plurality of sliders are connected by a slider connecting plate. The sliders include at least one fixed slider and at least one floating slider. The floating slider includes a sliding base block that slides on the linear slide rail.

[0004] As mentioned above, linear guides are typically connected to the base using bolts. Therefore, if the guides are not parallel after installation, the output components will not be able to move smoothly. In this case, it is necessary to re-drill holes, which is inconvenient and has room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide an adjustment device for linear guideways of machine tools to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustment device for a linear guideway of a machine tool, comprising a mounting frame, a guideway body placed inside the mounting frame, and an adjustment component installed between the mounting frame and the guideway body. The adjustment component has a mounting hole opened on the inner wall of the bottom of the mounting frame. An extension shaft is provided at one end of the outer wall of the bottom of the guideway body, and the extension shaft is rotatably connected to the inside of the mounting hole via a bearing. A limiting groove is opened on one side of the inner wall of the mounting frame, a movable seat is slidably inserted into the limiting groove, an adjustment rod is hinged inside the movable seat, and a hinge seat is provided on one side of the outer wall of the guideway body, with one end of the adjustment rod hinged inside the hinge seat.

[0007] As a further preferred embodiment of this technical solution, two mounting blocks are fixedly connected to the inner wall of one side of the mounting frame, and the two mounting blocks are rotatably connected to the same lead screw through a bearing, and the movable seat is threaded onto the outside of the lead screw.

[0008] As a further preferred embodiment of this technical solution, a worm gear is coaxially fixed at one end of the lead screw, and a horizontally arranged worm is rotatably connected inside the mounting block via a bearing, the worm meshing with the worm gear.

[0009] Even when two or more adjacent slide rails are not parallel, there is no need to drill holes in the external mounting base, making it more convenient to use and improving the installation efficiency of the device. If more than one is not parallel, it can be rotated by the knob drive. Through engagement, it can be driven to rotate slowly, ensuring that the adjustment process is precise enough. It drives the rotation within the two internal parts. Because the sliding plug connected to it cannot rotate in the middle, it can be driven to translate along the middle when rotated. One end is restricted to flipping. When the other end is driven to move, the tilt angle will also change. Since one end is connected to the middle part by rotating the shaft, the tilt angle will also change when the other end is displaced. It stops when multiple slide rails are parallel, and then it can be used.

[0010] As a further preferred embodiment of this technical solution, a sealing assembly is installed on the outside of the mounting frame. The sealing assembly includes a bidirectional lead screw rotatably connected to the inside of the mounting frame via bearings. The bidirectional lead screw is horizontally positioned. Two symmetrical sealing plates are placed on the top of the mounting frame. The two sealing plates are threaded onto the threads at both ends of the bidirectional lead screw, and the connecting parts of the two sealing plates are in contact with the inner wall of the mounting frame. A motor is fixedly installed on one outer wall of the mounting frame, and the output end of the motor is coaxially fixed with one end of the bidirectional lead screw.

[0011] When the outer one is activated, its output end drives the inner one to rotate, while the one that is in contact with the inner wall cannot rotate. This causes the two to move closer to each other, and then the two will block the internal space, thus preventing the internal components from being attached to external impurities, and they can also be quickly opened when maintenance is needed.

[0012] As a further preferred embodiment of this technical solution, an extension piece is provided on the outer wall of the two sealing plates that are close to each other, and both extension pieces are made of sponge material.

[0013] As a further preferred embodiment of this technical solution, one end of the bottom outer wall of the mounting frame is provided with an arc-shaped limiting groove 2, and the center of the limiting groove 2 coincides with the center of the mounting hole. The other end of the bottom outer wall of the slide rail body is fixedly connected to a limiting block 2, and the mounting hole is slidably connected to the limiting groove 2.

[0014] As a further preferred embodiment of this technical solution, one or more connection holes are provided on both sides of the bottom outer wall of the mounting frame.

[0015] This utility model provides an adjustment device for linear guideways in machine tools, which has the following advantages:

[0016] (1) By setting an adjustment component, this utility model can make it more convenient to use without secondary drilling of the external mounting base when two or more adjacent slide rails are not parallel, which is conducive to improving the installation efficiency of the device. If one or more are not parallel, the knob can be driven to rotate. The engagement can drive the rotation slowly, which can ensure that the adjustment process is accurate enough. The two slide rails rotate in the middle. Since the sliding plug connected to it cannot rotate in the middle, the rotation can drive the translation along the middle. One end is restricted to flipping. When the other end is driven to move, the tilt angle will also change. Since one end is connected to the middle through the rotating shaft, the tilt angle will also change when the other end is displaced. The tilt angle will change until the multiple slide rails are parallel and then stop.

[0017] (2) By setting up a closed component, the outer part is activated, and its output end is driven to rotate inside. The part that is attached to the inner wall cannot rotate, which can drive the two to move closer to each other. Then the two will block the internal space, thereby preventing the internal components from being attached by external impurities, and can be quickly opened when maintenance is needed.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] This utility model provides a technical solution: such as Figure 2 and Figure 3 As shown in this embodiment, an adjustment device for a machine tool linear guideway includes a mounting frame 1, a guideway body 2 placed inside the mounting frame 1, and an adjustment component 4 installed between the mounting frame 1 and the guideway body 2. The adjustment component 4 has a mounting hole 401 opened on the bottom inner wall of the mounting frame 1. An extension shaft is provided at one end of the bottom outer wall of the guideway body 2, and the extension shaft is rotatably connected to the inside of the mounting hole 401 through a bearing. A limiting groove 402 is opened on one side inner wall of the mounting frame 1. A movable seat 403 is slidably inserted into the limiting groove 402. An adjustment rod 404 is hinged inside the movable seat 403. A hinge seat is provided on one side outer wall of the guideway body 2, and one end of the adjustment rod 404 is hinged inside the hinge seat.

[0026] Two mounting blocks 405 are fixedly connected to the inner wall of one side of the mounting frame 1. The two mounting blocks 405 are rotatably connected by the same lead screw 406 through a bearing. The movable seat 403 is threaded onto the outside of the lead screw 406.

[0027] like Figure 3 and Figure 4 As shown, a worm gear 407 is coaxially fixed at one end of a lead screw 406. A horizontally arranged worm 408 is rotatably connected inside the mounting block 405 via a bearing. The worm 408 meshes with the worm gear 407. If one or more of them are not in a parallel state, the knob drives 408 to rotate. 408 can drive 407 to rotate slowly through meshing, which can ensure that the adjustment process is accurate enough.

[0028] 407 drives 406 to rotate inside the two 405s. Since 403, which is connected to it, is slidably inserted into 402 and cannot rotate, when 406 rotates, it can drive 403 to translate along 402. One end of 404 is restricted by 2 and can only rotate. When its other end is driven to move, the tilt angle of 404 will also change. Since one end of 2 is connected to 401 through a rotating shaft, when 404 drives the other end of 2 to move, the tilt of 2 will also change. It stops when the multiple 2s are parallel, and thus it can be used.

[0029] like Figure 1 and Figure 5 As shown, a sealing component 5 is installed on the outside of the mounting frame 1. The sealing component 5 includes a bidirectional lead screw 502 that is rotatably connected to the inside of the mounting frame 1 via bearings. The bidirectional lead screw 502 is horizontally arranged. Two symmetrical sealing plates 501 are placed on the top of the mounting frame 1. The two sealing plates 501 are threaded onto the threads at both ends of the bidirectional lead screw 502, and the connecting parts of the two sealing plates 501 are in contact with the inner wall of the mounting frame 1. A motor 503 is fixedly installed on one side of the outer wall of the mounting frame 1. The output end of the motor 503 is coaxially fixed with one end of the bidirectional lead screw 502.

[0030] like Figure 1 As shown, each of the two sealing plates 501 has an extension piece 504 on the outer wall of the side that is close to each other. Both extension pieces 504 are made of sponge material, which can deform to ensure that the sealing plate 501 can adapt to the state after adjusting the slide rail body 2 without creating gaps.

[0031] When 503 on the outside of 1 is activated, its output drives 502 to rotate inside 1. 501, which is attached to the inner wall of 1, cannot rotate. 502 can then drive the two 501 to move closer to each other. Subsequently, the two 501 block the internal space of 1, thereby preventing the internal components from being attached by external impurities, and can also be quickly opened when maintenance is required.

[0032] like Figure 2 and Figure 3 As shown, a limiting groove 409 with an arc shape is provided at one end of the bottom outer wall of the mounting frame 1, and the center of the limiting groove 409 coincides with the center of the mounting hole 401, so that the swing of the slide rail body 2 is not hindered by the limiting groove 409. The other end of the bottom outer wall of the slide rail body 2 is fixedly connected to the limiting block 410. The mounting hole 401 is slidably connected to the limiting groove 409. With the cooperation of the limiting block 410, the slide rail body 2 connected to it will not move upward during use, which helps to improve the stability of the slide rail body 2.

[0033] like Figure 2 and Figure 3 As shown, one or more connection holes 3 are opened on both sides of the bottom outer wall of the mounting frame 1.

[0034] This utility model provides an adjustment device for linear guideways in machine tools, the specific working principle of which is as follows:

[0035] When the device is working, the bolt is passed through 3 and connected to the external workbench. At this time, the position of 1 will be fixed. If more than one 2 is not in a parallel state, the knob drives 408 to rotate. 408, through engagement, can drive 407 to rotate slowly, which can ensure that the adjustment process is precise enough. 407 drives 406 to rotate inside the two 405. Because 403, which is connected to it, is slidably inserted in 402 and cannot rotate, the rotation of 406 can drive 403 to translate along 402. One end of 404 is restricted by 2 and can only rotate. When its other end is driven to rotate... When moved, the tilt angle of 404 will also change. Since one end of 2 is connected to 401 via a rotating shaft, if 404 drives the other end of 2 to move, the tilt of 2 will also change until the multiple 2s are parallel and stop. Thus, it can be used. Start 503 on the outside of 1. Its output end drives 502 to rotate inside 1. 501, which is attached to the inner wall of 1, cannot rotate. 502 can then drive the two 501s to move closer to each other. Then the two 501s will block the internal space of 1, thereby preventing the internal components from being attached by external impurities, and can be quickly opened when maintenance is needed.
