Technical Field
[0001] This utility model relates to the field of machining technology, specifically to a column for a machining center. Background Technology
[0002] Optical-mechanical (OMO) is a preliminary product of CNC machine tools. It consists of the main body and basic components such as the machine tool bed, saddle, worktable, column, guide rail, and headstock, forming the machine tool host, or the machine tool "skeleton". However, it does not yet include hydraulic transmission components, pneumatic components, electric motors and electrical components, as well as CNC systems and other components.
[0003] However, existing machining centers have various machining mechanisms installed on them. Among them, the drilling and cutting mechanisms are prone to vibration during operation. If the vibration cannot be effectively eliminated, it may cause deviations in machining accuracy. Therefore, it does not meet the current requirements. To address this, we propose a column for machining centers. Utility Model Content

[0009] Preferably, the plug-in plate is provided in two pieces, and a connecting plate is fixedly installed between the two plug-in plates. Each plug-in plate has a number of balls at one end. The plug-in plate and the connecting plate are inserted into the plug-in hole and fixed by bolts. The plug-in plate is located outside the fixed plate, and the balls are in rolling connection with the outer end of the fixed plate.
[0010] Preferably, the shock-absorbing component includes two sets of buffer plates, each set of buffer plates has two plates, and several springs and dampers are evenly fixed between the two buffer plates, with one buffer plate located in the mounting groove.
[0011] Preferably, another buffer plate is located at the lower end of the limiting groove, and a push plate is slidably inserted into the limiting groove, with the lower end of the push plate abutting against the upper end of the buffer plate.

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Please see Figures 1-4 This utility model provides a technical solution: a column for a machining center, comprising: a column body 3, a base 2 fixedly installed at the lower end of the column body 3, a shock absorber 1 provided at the lower end of the base 2, a sliding groove 4 and an installation groove 5 respectively provided on the left and right sides of the upper end of the shock absorber 1, the installation groove 5 being located inside the sliding groove 4, a fixing plate 13 fixedly installed at the rear end of the shock absorber 1, an insertion groove 7 provided on the front side of the upper end of the shock absorber 1, a through hole 8 corresponding to the insertion groove 7 provided at the front end of the base 2, an insertion hole 11 provided at the rear end of the base 2, a groove 12 provided on one side of the lower end of the base 2, the lower end of the insertion hole 11 communicating with the upper end of the groove 12, and a limiting groove 9 provided on both the left and right sides of the lower end of the base 2, the limiting groove 9 being located directly above the installation groove 5, and the limiting groove 9 being inverted convex in shape;
[0022] Limiting plates 10 are fixedly installed on both the left and right sides of the lower end of the base 2. The size of the limiting plates 10 is smaller than the size of the sliding groove 4. The base 2 can slide into the upper end of the shock absorber 1 from one side. At the same time, the limiting plates 10 are inserted into the sliding groove 4. The fixing plate 13 is located in the groove 12, which initially fixes the base 2 and the column body 3 to the upper end of the shock absorber 1. There are two plug-in plates 20, and a connecting plate 19 is fixedly installed between the two plug-in plates 20. Each plug-in plate 20 has several balls 21 at one end. The plug-in plates 20 and the connecting plate 19 are inserted into the plug-in holes 11 and fixed with bolts. At the same time, the lower end of the plug-in plate 20 is located in the groove 12 and is located outside the fixing plate 13. The balls 21 and the outer end of the fixing plate 13 are connected by rolling. When the base 2 and the column body 3 vibrate at the upper end of the shock absorber 1, the balls 21 roll outside the fixing plate 13 to guide and limit the base 2.
[0023] Rubber plates 6 are fixedly installed on both the left and right sides of the upper end of the shock absorber 1. The rubber plates 6 are located between the sliding groove 4 and the mounting groove 5. When the base 2 is installed on the upper end of the shock absorber 1, the lower end of the base 2 is located on the upper end of the rubber plate 6. The rubber plate 6 is made of hard rubber and can effectively absorb the vibration force received by the base 2 without changing its shape.
[0024] A shock-absorbing component is provided between the mounting groove 5 and the base 2. The shock-absorbing component includes two sets of buffer plates 16. Each set of buffer plates 16 has two plates. Several springs 14 and dampers 15 are evenly fixed between the two buffer plates 16. One of the buffer plates 16 is located in the mounting groove 5. The mounting groove 5 limits the buffer plate 16, springs 14 and dampers 15.
[0025] Another buffer plate 16 is located at the lower end of the limiting groove 9. The push plate 17 is convex and slides into the limiting groove 9. The upper end of the push plate 17 slides into the limiting groove 9. The lower end of the push plate 17 is inserted into the upper end of the buffer plate 16 through the compression spring 14 and the damper 15 and is fixed by bolts. The spring 14 and the damper 15 can absorb the vibration force on the base 2 and the column body 3.
[0026] The guide plate 18 is slidably inserted into the perforation 8. The lower end of the guide plate 18 is inserted into the insertion slot 7 and fixed by bolts. The guide plate 18 limits the base 2, allowing the base 2 to move in the vertical direction, thereby increasing the stability of the connection between the base 2 and the shock absorber 1.
[0027] In actual use, first insert the buffer plate 16 into the mounting groove 5, slide the base 2 from one side of the shock absorber 1 into the upper end of the shock absorber 1, and at the same time insert the limiting plate 10 into the sliding groove 4. The fixing plate 13 is located in the groove 12. Insert the plug plate 20 and the connecting plate 19 into the plug hole 11 and fix them with bolts. The lower end of the plug plate 20 is located outside the fixing plate 13. The ball bearing 21 is connected to the outer end of the fixing plate 13. When the base 2 and the column body 3 vibrate at the upper end of the shock absorber 1, the ball bearing 21 rolls outside the fixing plate 13. Then, insert the lower end of the guide plate 18 through the through hole 8 into the plug groove 7 and fix it with bolts. The spring 14 and the damper 15 can absorb the vibration force on the base 2 and the column body 3.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
