Description

Technical Field

[0001] The utility model relates to the technical field of vertical machining centers, and more specifically, to a multi-station clamping tooling for a vertical machining center. Background Art

[0002] A vertical machining center refers to a machining center with a spindle axis perpendicular to the workbench, which is mainly applicable to machining complex parts such as plates, discs, molds, and small shell parts. The vertical machining center can complete processes such as milling, boring, drilling, tapping, and cutting threads. The vertical machining center has at least three-axis two-linkage, generally can achieve three-axis three-linkage, and some can perform five-axis and six-axis control. When machining workpieces, in order to improve the machining efficiency, multi-station toolings have emerged, which can machine multiple parts at one time.

[0003] After retrieval, the utility model patent with the publication number of CN221495154U discloses a multi-station vertical machining center, which solves the problem that the clamping stations of the current multi-station vertical machining center are not convenient to move according to the machining requirements, affecting the machining efficiency of the machining center. It includes a machining center body, and both sides of the bottom end inside the machining center body are connected with moving plates. A clamping groove is opened at one end of the moving plate. In this patent, the rotating shaft drives the gear to rotate, so that the toothed plate drives the support plate to move upward along a straight line. The support rod drives the pull rod to move to one side under the pull of the support plate, and then the fixing plate moves outside the clamping groove. The fixing plate is fixedly connected to the moving plate again. The fixing seat is pushed to one side to change the position of the clamping seat, which is convenient for the clamping seat to move according to the volume of the part, facilitating the clamping of different parts, avoiding the inconvenience of fixing parts between multiple stations, and improving the work efficiency.

[0004] However, the above patent still has the following deficiencies: Although multi-station machining can be carried out on multiple clamping seats, a certain amount of time will be wasted during the loading and unloading process, affecting the machining efficiency; in addition, when machining the workpiece on the clamping seat, it will be subjected to a certain cutting force, and the stability of only fixing the fixing seat by inserting two fixing plates into the clamping groove is poor. For this reason, we propose a multi-station clamping tooling for a vertical machining center. Summary of the Utility Model

[0026] Embodiment:

[0027] Please refer to Figures 1-5 , a multi-station clamping tooling for a vertical machining center, including a machining center body 1. A machining chamber 2 is arranged at the front of the machining center body 1. A support base 3 is fixedly connected to the front surface of the machining center body 1.

A plurality of jacks 13 are opened on the side surface of the L-shaped sliding frame 10.

[0028] Specifically, please refer to Figure 1, Figure 4 and Figure 5 The fixing mechanism 11 includes a convex slide seat 21 sleeved inside two L-shaped slide frames 10. The top surface of the convex slide seat 21 is connected to the bottom surface of the clamping seat 12. A pushing groove 15 is formed in the bottom surface of the convex slide seat 21. Two ends of the pushing groove 15 are respectively provided with sliding grooves 19. Two groups of springs 16 are respectively fixedly connected to both sides of the inner cavity of the pushing groove 15. The end parts of the two groups of springs 16 are respectively fixedly connected with a moving plate 17. A latch 18 is respectively fixedly connected to the side surfaces of the two moving plates 17. The end part of the latch 18 extends to the outside of the convex slide seat 21 and is movably sleeved in the inner cavity of the jack 13. The two ends of the moving plate 17 are respectively fixedly connected with a pulling column 20. The end part of the pulling column 20 penetrates through the sliding groove 19 and extends to the outside of the convex slide seat 21.

[0029] In this embodiment, the moving plate 17 is pulled by the pulling column 20 so as to drive the latch 18 to move.

[0030] Specifically, please refer to Figure 1 and Figure 2 Two support frames 14 are fixedly connected to the front part of the machining center body 1. The top surface of the support frame 14 is in contact with the bottom surface of the rotating table 9. The bottom surface of the rotating table 9 is in contact with the bottom surface of the inner cavity of the machining chamber 2.

[0031] In this embodiment, the rotating table 9 is supported by the support frame 14 to ensure the stability of the rotation of the rotating table 9.

[0032] Specifically, please refer to Figure 1 Two outer box doors 22 are respectively slidably connected to both sides of the front part of the machining center body 1. A handle 23 is fixedly installed on the outer side of the outer box door 22. The bottom surface of the outer box door 22 is flush with the top surface of the rotating table 9.

[0033] In this embodiment, the inner cavity of the machining chamber 2 is blocked by the outer box door 22, and the outer box door 22 is driven to move by holding the handle 23 with the hand.

[0034] Specifically, please refer to Figure 1 , Figure 4 and Figure 5 The side surface of the convex slide seat 21 is in contact with the inner side surface of the L-shaped slide frame 10.

[0035] In this embodiment, the stability of the convex slide seat 21 inserted into the inner sides of the two L-shaped slide frames 10 is ensured.

[0036] Specifically, please refer to Figure 4 and Figure 5 The outer diameter of the latch 18 is equal to the inner diameter of the jack 13.

[0037] In this embodiment, the stability of the insertion pin 18 inserted into the inner cavity of the jack 13 is ensured, thereby ensuring the stability of the convex slide seat 21 fixed inside the two L-shaped slide frames 10.

[0038] Working principle: During use, the controller built in the machining center body 1 is used to control the brake motor 7 to start regularly. The brake motor 7 drives the first gear 8 to rotate intermittently. The meshing transmission between the first gear 8 and the second gear 6 drives the drive shaft 5 and the turntable 9 to rotate intermittently by 180 degrees, so that the clamping seats 12 on the two L-shaped slide frames 10 intermittently move into the processing chamber 2 for processing. At the same time, blanking and reloading are performed on the clamping seats 12 moved to the outside of the machining center body 1. When processing the workpiece in the inner cavity of the processing chamber 2, the sliding outer box door 22 is slid to protect the outside of the processing chamber 2.

[0039] In addition, when it is necessary to adjust the distance between the two clamping seats 12, the operating column 20 is pulled to drive the moving plate 17 to move. The moving plate 17 drives the insertion pin 18 to disengage from the inner cavity of the jack 13 to release the fixation between the convex slide seat 21 and the L-shaped slide frame 10, so that the convex slide seat 21 and the clamping seat 12 can slide on the two L-shaped slide frames 10, thereby adjusting the distance between the two clamping seats 12. After adjustment, the elastic force of the spring 16 drives the insertion pin 18 to re-insert into other jacks 13 to fix the L-shaped slide frame 10 and the convex slide seat 21 again.

[0040] In addition, different numbers of convex slide seats 21 can be inserted into the two L-shaped slide frames 10 according to actual conditions, so as to install different numbers of clamping seats 12 on the two L-shaped slide frames 10, so that multiple workpieces can be clamped and processed at one time. That's all.

[0041] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improvement concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
