Description

Technical Field

[0001] The invention relates to the field of round parts finishing equipment, and in particular to a vertical turning-grinding composite machine tool. Background Art

[0003] At present, when a machine tool is used to process a circular part, the surface of the circular part needs to be finely processed by turning first and then grinding to obtain a circular part that meets the use accuracy. However, when designing existing machine tools, the turning machine tool and the grinding machine tool are designed separately, which results in the need to first clamp the circular part on the turning machine tool for fine turning, and then remove it from the turning machine tool and clamp it again on the grinding machine tool for fine grinding. Since the circular part is clamped repeatedly, it is difficult to ensure the processing accuracy of the circular part due to repeated clamping. Secondly, in order to achieve stable limited clamping of circular parts, existing machine tools usually use magnetic suction cup clamps to magnetically clamp and fix circular parts. During processing, the magnetic suction cup clamp is driven to rotate by the rotating worktable to drive the circular parts to make a turnover motion. However, when driving the rotary worktable, the existing machine tools usually use gear transmission. This causes radial runout of the rotary worktable due to the meshing gap between teeth during operation, which directly further reduces the processing accuracy of the circular parts. Moreover, as the service life increases, the gear meshing wear increases, and the processing accuracy of the circular parts will be further reduced. Summary of the invention

Specifically, the vertical turning assembly 4 includes a vertical lathe frame 404, a worm gear 402, a fixed seat 405 and a ram mechanism 406. The front part of the vertical lathe mounting support plate 2 is combined with a vertical lathe frame 404, and the front part of the vertical lathe frame 404 is combined with a worm gear 402 with an axis arranged along the longitudinal direction, and the front rotation connection of the worm gear 402 A fixed seat 405 is connected, and an adjustment worm 401 meshing with the outer top of the worm wheel 402 is installed horizontally on the top of the fixed seat 405, so as to drive the fixed seat 405 to swing and adjust the turning angle by manually rotating the adjustment worm 401 and the worm wheel 402.

[0031] By adopting the above structure, specifically in the process of performing integrated turning and grinding finishing on the part body 9, since the horizontal high-precision linear rail mechanism 13 at the front part of the beam body 3 is installed with a vertical lathe mounting pallet 2 and a vertical mill mounting pallet 1 that can slide linearly independently, and the front parts of the vertical lathe mounting pallet 2 and the vertical mill mounting pallet 1 are respectively combined and installed with a vertical turning assembly 4 and a vertical grinding assembly 7, the part body 9 clamped on the static pressure rotary worktable 11 can be first fine-turned and then fine-ground by the vertical turning assembly 4 and the vertical grinding assembly 7, and an operation mode of completing fine turning and fine grinding of the part body 9 by clamping it once is realized, and there is no need to repeatedly clamp the part body 9, which is beneficial to improving the processing of the part body 9. Precision control, specifically when processing the part body 9, a turning tool that meets the processing requirements is selected and installed on the vertical turning tool holder 407 of the vertical turning assembly 4, so that the vertical grinding assembly 7 is moved laterally away from the part body 9 and the vertical turning assembly 4 by the vertical grinding mounting bracket 1 along the horizontal high-precision linear rail mechanism 13 linear movement, and then the vertical turning assembly 4 is controlled to move laterally close to the part body 9 by the vertical lathe mounting bracket 2 along the horizontal high-precision linear rail mechanism 13 linear movement, and the part body 9 is fine-turned by the vertical turning assembly 4. After the fine-turning is completed, the vertical turning assembly 4 is moved laterally away from the part body 9 and the vertical grinding assembly 7 by the vertical lathe mounting bracket 2 along the horizontal high-precision linear rail mechanism 13 linear movement, and then through The vertical mill mounting support plate 1 controls the vertical grinding assembly 7 to move horizontally close to the part body 9 in a linear manner along the lateral high-precision linear rail mechanism 13, and uses the vertical grinding assembly 7 to perform fine grinding on the part body 9, thereby realizing the integrated collaborative processing of fine turning and fine grinding of the part body 9, that is, first fine turning and then fine grinding. Since the part body 9 only needs to be clamped once, the two processes of fine turning and fine grinding can be completed sequentially, thereby realizing the coordinated fine turning and fine grinding of the part body 9, and at the same time, the adverse effect on the processing accuracy due to repeated clamping is eliminated. Specifically, when the part body 9 is clamped and fixed, a magnetic suction cup clamp 10 is installed on the top combination of the static pressure rotating worktable 11, so that the part body 9 can be quickly fixed by the magnetic suction cup clamp 10. The fast magnetic fixation makes the clamping and fixing of the part body 9 stable and easy to implement. At the same time, since the worktable spindle 1101 at the bottom of the hydrostatic rotary table 11 is connected to the driven pulley 1501 of the synchronous belt drive assembly 15, the method of driving the hydrostatic rotary table 11 to rotate through the synchronous belt drive assembly 15 replaces the gear transmission to drive the hydrostatic rotary table 11 to rotate, thereby avoiding the radial runout of the hydrostatic rotary table 11 during the rotation process, eliminating the adverse effect of the radial runout of the hydrostatic rotary table 11 on the processing accuracy, which is conducive to further improving the processing accuracy control of the part body 9. In addition, since the top surface of the base 6 is combined with the dresser assembly 8 near the side of the vertical grinding assembly 7,In this way, the arc dresser 801 and the diamond pen dresser 802 of the dresser assembly 8 can directly perform arc dressing and end face dressing on the grinding wheel body 708, respectively. The arc dressing and end face dressing of the grinding wheel body 708 are simple and easy to implement, and the centralized integration of the dressing operation of the grinding wheel body 708 is realized, meeting the processing and use needs of the grinding wheel body 708.

[0032] It should be confirmed that in the design and production of the above-mentioned vertical turning and grinding composite machine tool, a high-precision machine tool manufacturing mother machine should be used for processing to achieve precision processing of the machine tool mounting surface, bed, and guide rail mounting surface to ensure that the installation requirements of the high-precision machine tool are met. At the same time, manual scraping, high-precision instrument calibration, and repeated coloring and scraping can be used to achieve precision processing of certain difficult-to-machine areas to ensure that the above-mentioned vertical turning and grinding composite machine tool can perform integrated turning and grinding of the part body 9 to the expected design accuracy after production and assembly.

[0033] At the same time, the above-mentioned vertical turning and grinding composite machine tool is also equipped with a lubricating oil pressure station, which is responsible for the lubrication of the linear rails, screws and rotary worktables involved. The lubricating oil pressure station is equipped with an oil cooler to prevent the accuracy from being unstable due to excessive oil temperature. It is also equipped with a coolant supply system to provide coolant during the fine turning and fine grinding process. The cooling water tank of the coolant supply system is equipped with a filter device to filter the debris generated during the cutting and grinding process of parts. The coolant supply system is also equipped with a water cooler to control the coolant temperature and ensure the temperature of the processed parts.

Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
