Method used

Based on above-mentioned disadvantages, as shown in Figure 1-4, the top of guide rail base 2 of the present invention is locked and fixed with guide rail pressure plate 4 by some hexagon socket head screws 3 densely distributed in rows, and the inner hexagon on guide rail base 2 There are two rows of screws 3, and the denser row is close to one side of the static pressure slider 6. Compared with the traditional locking arrangement of thick screws and wide spacing screws, the locking structure of the present invention adopts small The screws have a unique narrow spacing and arrangement, so that the guide rail pressure plate 4 can meet the firm and stable requirements after installation, and at the same time, it can evenly distribute the locking force from the hexagon socket hea...

Abstract

The invention discloses an anti-deforming guide rail mounting structure of an ultra-precision aspheric surface forming grinding machine, and belongs to the technical field of anti-deforming guide railmounting structures. The anti-deforming guide rail mounting structure comprises a workbench base, and guide rail bases are arranged on the front side and the rear side of the top of the workbench base. A guide rail pressing plate is locked and fixed to the top of the guide rail base through a plurality of rows of socket head cap screws closely arranged in an array, and a workbench is arranged atthe top of the guide rail pressing plate. The workbench and the guide rail pressing plate achieve transverse sliding by arranging a static pressure sliding block, threaded holes matched with the socket head cap screws are formed in the top of the guide rail base, and anti-distortion counter bores are formed in upper end openings of the threaded holes. According to the anti-deforming guide rail mounting structure of the ultra-precision aspheric surface forming grinding machine, the key causing factor causing protruding deformation of the top face of the guide rail pressing plate can be eliminated, and then the function of preventing stress deformation is achieved.

Example Embodiment

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the invention in conjunction with the accompanying drawings in the embodiments of the invention. Obviously, the described embodiments are only a part of the embodiments of the invention, rather than all of them. Based on the embodiments of the invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the invention.

[0023] See Figure 1-4 , The invention provides a technical solution: an ultra-precision aspherical surface forming grinder anti-deformation guide rail installation structure, including a workbench base 1, the top and rear sides of the workbench base 1 are provided with a guide rail base 2, the guide rail The top of the base 2 is locked and fixed with a guide rail pressing plate 4 by a number of densely packed rows of hexagonal socket screws 3, the top of the guide rail pressing plate 4 is provided with a worktable 5, and a static state is provided between the worktable 5 and the guide rail pressing plate 4 The pressing slider 6 realizes lateral sliding, the top of the guide rail base 2 is provided with a threaded hole 7 that matches with the hexagon socket screw 3, and the upper port of the threaded hole 7 is provided with an anti-distortion counterbore 8.

[0024] Further, the hexagon socket screws 3 on the guide rail base 2 are provided in two rows, and the distance between the two rows is 30mm. One row of the hexagon socket screws 3 is 30mm apart, and the other row of the hexagon socket screws 3 The spacing is 60mm.

[0025] Further, a row of the hexagon socket screws 3 with a pitch of 30 mm is close to one side of the static pressure slider 6.

[0026] Further, the size specification of the hexagon socket screw 3 is M8.

[0027] Further, the aperture of the anti-distortion counterbore 8 is 9mm and the depth is 9mm.

[0028] A specific application of this embodiment is:

[0029] The invention discloses an anti-deformation guide rail installation structure of an ultra-precision aspherical forming grinder;

[0030] The traditional guide rail installation structure uses large-size screws, the screw spacing is relatively large, the force is relatively uneven, and it is easy to cause deformation of the guide rail surface; Figure 5 As shown, the top port (X) of the traditional threaded hole is chamfered or not processed, and the thread on the top is pulled by the screw during installation and easily protrudes from the mounting surface, resulting in uneven mounting surface and easily deforming the guide rail.

[0031] Based on the above drawbacks, such as Figure 1-4 As shown, the top of the guide rail base 2 of the present invention is locked and fixed with a guide rail pressing plate 4 by a number of rows of densely arranged hexagon socket screws 3, and the guide rail base 2 is provided with two rows of hexagon socket screws 3, a denser row Close to one side of the static pressure slider 6, compared to the traditional thick screw and wide-spacing screw locking arrangement, the locking structure of the present invention adopts small screws and a unique narrow spacing and arrangement method, so that After the guide rail presser 4 is installed, it can not only meet the requirements of firmness and stability, but also spread the locking force from the hexagon socket screw 3 on the top of the guide rail base 2 to a larger stress area, reducing the circumference of each threaded hole 7 on the top of the guide rail base 2 Part of the force is applied to prevent the force from being deformed;

[0032] As a specific embodiment, the hexagon socket screws 3 on the guide rail base 2 are provided in two rows, and the spacing between the two rows is 30mm. One row of the hexagon socket screws 3 has a spacing of 30mm, and the other row of the hexagon socket screws 3 is 30mm apart. The spacing of the screws 3 is 60 mm.

[0033] Further, the upper port of the threaded hole 7 of the present invention is provided with an anti-distortion counterbore 8 structure. When the hexagon socket screw 3 is screwed with the threaded hole 7, the diameter of the anti-distortion counterbore 8 is larger than the outer diameter of the hexagon socket screw 3. The upper port of the threaded hole 7 is a non-contact area, which can completely avoid stress, so it can eliminate the key cause of the convex deformation of the top surface of the guide rail pressure plate 4, and further prevent the force from being deformed;

[0034] As a specific embodiment, the size specification of the aforementioned hexagon socket screw 3 is M8, the aperture of the anti-distortion counterbore 8 is 9mm, and the depth is 9mm.

[0035] The installation structure is not limited to the size exemplified in this embodiment. In actual application, it can be adjusted accordingly according to the size of the equipment table.

[0036] In the description of the invention, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "other end", "upper", "one side", "top" , "内", "front", "center", "both ends", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, rather than indicating It may also imply that the pointed device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the invention.

[0037] In the present invention, the terms "installation", "setting", "connection", "fixing", "spinning" and other terms should be understood in a broad sense, unless otherwise clearly specified and limited. For example, they can be fixed connection or It can be detachably connected or integrated; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal communication of two components or the interaction relationship between two components, Unless specifically defined otherwise, those of ordinary skill in the art can understand the specific meanings of the above-mentioned terms in the invention according to specific circumstances.
