Description

Technical Field

[0001] The invention relates to the technical field of vertical machining centers, in particular to a vertical machining center with a guide rail wear prevention structure. Background Art

[0002] A vertical machining center refers to a machining center in which the spindle axis is set perpendicular to the worktable. It is mainly suitable for machining complex parts such as plates, discs, molds and small shells. A vertical machining center can complete processes such as milling, boring, drilling, tapping and cutting threads. A vertical machining center has at least three axes and two linkages, and generally can achieve three axes and three linkages. Some can perform five-axis and six-axis control. The column height of a vertical machining center is limited, and the processing range of box-type workpieces is limited.

[0003] Publication No. CN 217255011 U discloses a vertical machining center with an anti-deviating structure. The top of the transport plate is movably connected with a moving block. The middle end of the moving block is provided with an anti-deviating area. The workpiece is placed on the top of the displacement limiting tube. The weight of the workpiece itself causes the displacement limiting tube to press the compression spring A downward, so that the displacement limiting tube presses the shifting plate downward. Since the connection between one side of the shifting plate and one side of the shifting rod is connected by a limiting disc, the shifting plate presses the compression spring B downward so that the top of the shifting rod clamps the workpiece to prevent the workpiece from being positionally shifted when being engraved. During clamping, the sponge layer and the hard rubber layer are deformed to prevent the clamping part of the workpiece from being worn, and the anti-wear layer is provided to prevent the protective block from being worn. After engraving, the workpiece is moved out from the top of the displacement limiting tube. At this time, the compression spring B pushes the shifting plate upward, so that the shifting rod moves to its original position, which is convenient for next use. However, the following problems still exist in the actual use of this patent:

[0004] Although the vertical machining center with an anti-deviation structure can prevent the workpiece from being shifted when being engraved, during the machining process of the vertical machining center, the movement of the movable plate is achieved only through the threaded connection between the threaded hole block and the threaded shaft, resulting in insufficient supporting force for the movable plate, thereby affecting the stability of the movement of the movable plate. The prior art uses a slide rail for movement, but since a sliding connection is used for movement, and a certain amount of dust and particles adhere to the surface of the slide rail, the slide rail is damaged, which is not conducive to improving the service life of the slide rail.

[0005] A vertical machining center with a guide rail wear prevention structure is proposed to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a vertical machining center with a guide rail wear prevention structure to solve the problem that although the vertical machining center with an anti-deviation structure proposed in the above background technology can avoid the position deviation of the workpiece when it is engraved, during the processing of the vertical machining center, the movement of the movable plate is achieved only through the characteristics of the threaded connection between the threaded hole block and the threaded shaft, resulting in insufficient supporting force of the movable plate, thereby affecting the stability of the movement of the movable plate. In the prior art, the movement is carried out by means of slide rails, but since the movement is carried out by means of a sliding connection, and a certain amount of dust and particles will adhere to the surface of the slide rails, the slide rails will be damaged, which is not conducive to improving the service life of the slide rails.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the vertical machining center with a guide rail wear prevention structure can reduce the wear of the machine tool rails and improve the smoothness of the sliding of the machine tool guide rails by replacing the sliding friction between the moving roller and the first extra-wide guide rail, the second extra-wide guide rail and the third extra-wide guide rail with rolling friction, and improve the smoothness of the sliding of the machine tool guide rails. The adjusting threaded rod is driven to rotate by turning the adjusting knob, so that the adjusting threaded sleeve drives the adjusting bracket and the cleaning brush to move up and down, so that the cleaning brush can always contact the surface of the first extra-wide guide rail, the second extra-wide guide rail and the third extra-wide guide rail, thereby cleaning the dust on the surface of the first extra-wide guide rail, the second extra-wide guide rail and the third extra-wide guide rail. The specific contents are as follows:

[0022] 1. By setting the guide rail anti-wear mechanism, not only can the transverse motor be used to drive the transverse threaded rod to rotate, so that the transverse threaded sleeve drives the longitudinal bracket to move horizontally, the longitudinal motor can be used to drive the longitudinal threaded rod to rotate, so that the longitudinal threaded sleeve drives the processing table to move longitudinally, and the lifting motor can be used to drive the lifting threaded rod to rotate, so that the lifting threaded sleeve drives the second lifting bracket to move up and down. By adjusting the height of the processing equipment, the transverse and longitudinal positions of the workpiece to be processed can be adjusted at the same time, so that the workpiece can be moved in all directions, and the position adjustment of the processing center can be realized through the first ultra-wide guide rail, the second ultra-wide guide rail and the third ultra-wide guide rail. The adjustment of the workpiece is improved to facilitate the processing of the workpiece. The position of the workpiece is adjusted by the moving roller inside the roller bracket. The rolling friction between the moving roller and the first extra-wide guide rail, the second extra-wide guide rail and the third extra-wide guide rail replaces the sliding friction, which can reduce the wear of the machine tool rail and improve the smoothness of the sliding of the machine tool rail. At the same time, the service life of the first extra-wide guide rail, the second extra-wide guide rail and the third extra-wide guide rail can be increased. When blocking friction occurs between the moving roller and the first extra-wide guide rail, the second extra-wide guide rail and the third extra-wide guide rail, the moving roller will be driven to vibrate. When the movable roller vibrates, the first supporting spring and the telescopic sleeve will be compressed, so that the sponge connecting rod and the sealing plug inside the telescopic sleeve will move upward. When the sealing plug is separated from the oil leakage hole at the bottom of the oil storage tank, the lubricating oil inside the oil storage tank will flow into the oil absorption sponge along the oil leakage hole and be absorbed. Through the characteristic of the sliding connection between the oil absorption sponge and the movable roller, the lubricating oil can be evenly applied to the surface of the movable roller, and the lubricating oil can reduce the friction between the movable roller and the first extra-wide guide rail, the second extra-wide guide rail and the third extra-wide guide rail, thereby reducing the risk of guide rail wear, and further improving the first extra-wide guide rail, the second extra-wide guide rail and the third extra-wide guide rail. The service life of the second extra-wide guide rail and the third extra-wide guide rail is extended. When the workpiece placed on the top of the processing table is heavy, the first rotating connecting rod and the bevel gear transmission assembly are driven to rotate by rotating the rotating knob, so that the bevel gear transmission assembly drives the supporting threaded rod to rotate, and at the same time, the supporting threaded sleeve drives the first supporting rotating rod to move up and down. By utilizing the elastic force of the second supporting spring at the end of the supporting sliding rod, the second supporting rotating rod and the connecting support can support the roller bracket, thereby preventing the roller bracket from being compressed too much, resulting in a large separation of the sealing plug and the oil leakage hole, causing a large amount of lubricating oil to flow out, resulting in a waste of lubricating oil;

[0023] 2. By setting up the cleaning mechanism, not only can the cleaning bracket be used to shield the roller groove to prevent dust or particles from entering the roller groove, thereby affecting the adjustment smoothness of the machining center, but also dust and particles can be prevented from adhering to the lubricating oil, thereby affecting the rotation smoothness of the moving roller. By turning the adjusting knob to drive the adjusting threaded rod to rotate, the adjusting threaded sleeve drives the adjusting bracket and the cleaning brush to move up and down, so that the cleaning brush can always be in contact with the surface of the first extra-wide guide rail, the second extra-wide guide rail and the third extra-wide guide rail, thereby cleaning the dust on the surface of the first extra-wide guide rail, the second extra-wide guide rail and the third extra-wide guide rail, further reducing the wear caused by the machining center, and prolonging the service life of the first extra-wide guide rail, the second extra-wide guide rail and the third extra-wide guide rail.

The workpiece position is adjusted by the moving roller 134 inside the roller bracket 133. The rolling friction between the moving roller 134 and the first extra-wide guide rail 104, the second extra-wide guide rail 110 and the third extra-wide guide rail 118 replaces the sliding friction, which can reduce the wear of the machine tool track and improve the smoothness of the sliding of the machine tool guide rail. At the same time, the service life of the first extra-wide guide rail 104, the second extra-wide guide rail 110 and the third extra-wide guide rail 118 can be improved.

[0043] Secondly, when blocking friction occurs between the moving roller 134 and the first extra-wide guide rail 104, the second extra-wide guide rail 110 and the third extra-wide guide rail 118, the moving roller 134 will be driven to vibrate. When the moving roller 134 vibrates, the first supporting spring 132 and the telescopic sleeve 131 are compressed, so that the sponge connecting rod 136 and the sealing plug 137 inside the telescopic sleeve 131 move upward. When the sealing plug 137 is separated from the oil leakage hole 130 at the bottom of the oil storage tank 128, the lubricating oil inside the oil storage tank 128 will flow into the oil absorbing sponge 135 along the oil leakage hole 130 and be absorbed. Through the characteristic of the sliding connection between the oil absorbing sponge 135 and the moving roller 134, the lubricating oil can be evenly applied to the surface of the moving roller 134, and the lubricating oil can reduce the friction between the moving roller 134 and the first extra-wide guide rail 104, the second extra-wide guide rail 110 and the third extra-wide guide rail 1 18, thereby reducing the risk of guide rail wear and further improving the service life of the first extra-wide guide rail 104, the second extra-wide guide rail 110 and the third extra-wide guide rail 118. When the workpiece placed on the top of the processing table 115 is heavy, the first rotating connecting rod 139 and the bevel gear transmission assembly 140 are driven to rotate by rotating the rotating knob 138, so that the bevel gear transmission assembly 140 drives the supporting threaded rod 141 to rotate, and at the same time, the supporting threaded sleeve 142 drives the first supporting rotating rod 143 to move up and down, and utilizes the elastic force of the second supporting spring 145 at the end of the supporting sliding rod 144 to achieve the second supporting rotating rod 147 and the connecting support 148 to support the roller bracket 133, so as to avoid the roller bracket 133 from being compressed too much, resulting in a large separation of the sealing plug 137 and the oil leakage hole 130, causing a large amount of lubricating oil to flow out, resulting in a waste of lubricating oil.

[0044] Finally, the cleaning bracket 201 is used to block the roller groove 127 to prevent dust or particles from entering the roller groove 127, thereby affecting the adjustment smoothness of the machining center, and at the same time preventing dust and particles from adhering to the lubricating oil, thereby affecting the rotation smoothness of the moving roller 134. The adjusting threaded rod 204 is driven to rotate by rotating the adjusting knob 203, so that the adjusting threaded sleeve 205 drives the adjusting bracket 206 and the cleaning brush 207 to move up and down, so that the cleaning brush 207 can always be in contact with the surface of the first extra-wide guide rail 104, the second extra-wide guide rail 110 and the third extra-wide guide rail 118, thereby cleaning the dust on the surface of the first extra-wide guide rail 104, the second extra-wide guide rail 110 and the third extra-wide guide rail 118, further reducing the degree of wear caused by the machining center, and prolonging the service life of the first extra-wide guide rail 104, the second extra-wide guide rail 110 and the third extra-wide guide rail 118.
