Abstract
Description
Technical Field
[0001] This utility model relates to the field of vertical machine tool technology, specifically to a base structure for a vertical machine tool. Background Technology
[0002] In the field of machining, vertical machine tools are widely used in precision parts milling, drilling, tapping, and other machining processes due to their compact structure, small footprint, and high rigidity. The base, as the core supporting component of a vertical machine tool, directly affects the machine's overall stability, vibration resistance, and machining accuracy.
[0003] Chinese utility model patent CN216442020U discloses a vertical machine tool base structure with direct spindle gear drive. This base structure enhances transmission torque by employing a direct spindle gear drive structure, where multiple gear mechanisms drive the machining surface. Simultaneously, an inclined surface between the circular groove and the base bottom facilitates the outflow of cutting fluid. However, while multi-stage gear transmission increases torque, it also leads to increased energy loss and reduced transmission efficiency, potentially causing significant noise and wear, especially at high speeds. Furthermore, while the inclined surface does facilitate cutting fluid outflow, it does not address the issue of cutting fluid contamination.
[0004] Therefore, we propose a base structure for a vertical machine tool to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this utility model is to provide a base structure for a vertical machine tool to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A base structure for a vertical machine tool includes a base, a mounting seat on one side of the base, a circular fixing groove in the middle of the base, a drive component passing through the middle of the fixing groove, a processing table on the top surface of the base, an input end of the drive component being disposed in the mounting seat, and an output end of the drive component being connected to the bottom surface of the processing table.
[0008] The processing table has a flow guide channel on the base, and two collection cylinders are set on the bottom wall of the base below the flow guide channel.
[0009] According to the above technical solution, the processing table is arranged in a frustum shape, and several inclined downward guide grooves are provided on the top surface of the processing table. The guide grooves are distributed along the circumferential direction, and the guide groove is located on one side below the end of the guide groove.
[0010] According to the above technical solution, two mounting rings are fixedly installed on the bottom wall of the base, and the top end of the collecting cylinder is fixed in the mounting ring by a threaded connection. Two guide holes are opened in the guide groove, and the guide holes on the same side are concentrically set with the mounting ring.
[0011] According to the above technical solution, a number of reinforcing members are uniformly fixed along the circumferential sidewall of the fixing groove, and the reinforcing members are triangular steel structures.
[0012] According to the above technical solution, the drive assembly includes a worm, a worm wheel, a first gear, a second gear, and a transmission disk. The worm meshes with the worm wheel for transmission. The worm is mounted on the outer wall of the mounting base and is arranged along its width direction. The first gear is coaxially connected to the worm wheel and is rotatably disposed inside the mounting base. The transmission disk is rotatably disposed in a fixed groove. The processing table and the transmission disk are synchronously rotated through a shaft connection.
[0013] According to the above technical solution, the second gear is located below the bottom wall of the base and is also connected to the transmission disk by a shaft for synchronous rotation. A connecting frame is also fixedly installed between the side walls of the base. The second gear is also rotatably mounted on the connecting frame by a shaft. A toothed belt is also provided between the first gear and the second gear.
[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0015] 1. By setting up a drive component, a worm gear and gear belt are used to replace the effect of multi-stage gear meshing transmission, which reduces energy consumption, noise and wear.
[0016] 2. By setting an inclined guide channel II on the machining table and opening a guide channel I on the base, the cutting fluid can carry impurities and debris along with it when it flows down, and can automatically flow from the guide hole into the collection cylinder for collection, effectively solving the problem of cutting fluid contamination.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-5 The present invention provides the following technical solution:
[0025] A base structure for a vertical machine tool includes a base 2. A mounting seat 1 is fixedly installed on one side of the base 2 by bolts. The mounting seat 1 is used to install and fix the column. A circular fixing groove is opened in the middle of the base 2. A drive assembly 4 is arranged through the middle of the fixing groove. Several reinforcing members 21 are evenly fixed along the circumferential sidewall of the fixing groove. The reinforcing members 21 are triangular steel structures. A processing table 3 is arranged on the top surface of the base 2. The input end of the drive assembly 4 is arranged in the mounting seat 1, and the output end of the drive assembly 4 is connected to the bottom surface of the processing table 3.
[0026] Drive assembly 4 includes a worm 41, a worm wheel 42, a first gear 43, a second gear 44, and a transmission disc 46. The worm 41 meshes with the worm wheel 42 for transmission. Two bearing seats are fixedly mounted on one side of the outer wall of the mounting base 1 by screws. The worm 41 is rotatably mounted between the side walls of the two bearing seats via a shaft connection. A rotary motor is fixedly mounted on one of the bearing seats, and the rotary motor drives the worm 41. The first gear 43 is coaxially connected to the worm wheel 42, and both are rotatably mounted inside the mounting base 1 (i.e., a cavity is opened inside the mounting base 1, allowing the worm wheel to pass through). Both wheel 42 and gear 43 are located in the cavity, with gear 43 located above worm gear 42. The transmission disk 46 is rotatably mounted in the fixed groove. The processing table 3 and the transmission disk 46 are connected by a shaft and rotate synchronously. Gear 44 is located below the bottom wall of the base 2 and is also connected by a shaft to the transmission disk 46 and rotate synchronously. A connecting frame 25 is also fixedly mounted between the side walls of the base 2. Gear 44 is also rotatably mounted on the connecting frame 25 via a shaft. A toothed belt 45 is also provided between gear 43 and gear 44.
[0027] It should be further explained that by starting the rotary motor, it drives the worm 41 to rotate. With the output of the worm 41, the worm wheel 42 synchronously drives the gear 43 to rotate. Under the action of the toothed belt 45, the gear 44 rotates synchronously with the gear 43, and then drives the worktable to rotate and adjust together through the transmission plate 46.
[0028] The processing table 3 has a flow guide groove 22 on the base 2. Below the flow guide groove 22, two collection cylinders 24 are set on the bottom wall of the base 2. The processing table 3 is set in a frustum-shaped structure. Several downward inclined flow guide grooves 31 are set on the top surface of the processing table 3. The flow guide grooves 31 are distributed along the circumference. The flow guide groove 22 is located on one side below the end of the flow guide groove 31. Two mounting rings 23 are fixedly installed on the bottom wall of the base 2. The top of the collection cylinder 24 is fixed in the mounting ring 23 by a threaded connection. Two flow guide holes 221 are opened in the flow guide groove 22. The flow guide holes 221 on the same side are concentrically set with the mounting rings 23.
[0029] It should be further explained that when the cutting fluid flows down, it first flows down along the second guide groove 31 on the machining table 3, and then flows down into the collection cylinder 24 installed on the bottom wall of the base 2 through the guide hole 221 of the first guide groove 22. After machining is completed, the collection cylinder 24 can be unscrewed from the mounting ring 23 to remove the cutting fluid.
[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
