This improves workpiece changing efficiency, eliminates the need for workers to enter the machining center to operate fixtures, enhances safety and reduces labor, and increases the automation level of the equipment.

[0003] Regarding the aforementioned technologies, the inventors believe that they suffer from the following drawbacks: Existing automatic material changing devices are complex in structure, expensive, and have stringent requirements for the working environment, making them difficult to promote and apply in ordinary processing workshops. Furthermore, some material changing devices lack versatility, only adapting to materials of specific specifications and failing to meet diverse production needs. Moreover, existing material changing devices lack precision in material positioning and clamping during the changing process, easily leading to displacement during processing and increased processing errors. Therefore, we propose an automatic material changing device for vertical machining centers to solve the aforementioned problems. Utility Model Content

[0014] Beneficial effects

[0015] This utility model provides an automatic material changing device for a vertical machining center. Compared with the prior art, it has the following advantages:

[0016] This vertical machining center uses an automatic material changing device to achieve the material changing function through simple and mutually cooperating components such as guide rail mechanism, displacement mechanism, and sliding mechanism.

[0025] 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.

[0026] Please see Figures 1-6This utility model provides a technical solution: an automatic material changing device for a vertical machining center, including a guide rail mechanism 1, a displacement mechanism 2 installed inside the guide rail mechanism 1, a guide frame assembly 2011 fixedly connected to the front end face of the displacement mechanism 2, and a sliding mechanism 3 fixedly connected inside the guide frame assembly 2011.

[0027] A servo motor B301 is mounted on the bottom end face of the sliding mechanism 3. A circular base plate assembly 3011 is mounted on the top output shaft of the servo motor B301. Two guide rail assemblies 3012 are fixedly connected in a linear array on the top surface of the base plate assembly 3011. Two clamping push rods 3013 are fixedly connected in opposite directions on the inner sides of the two guide rail assemblies 3012.

[0028] The inner sides of the two clamping push rods 3013 are fixedly connected to the moving components 3014, the front and rear sides of the moving components 3014 are fixedly connected to the guide block components 3015, and the outer side of the moving components 3014 is fixedly connected to the clamping components 3016 for clamping the workpiece.

[0029] The displacement mechanism 2 is installed through the guide rail mechanism 1. The displacement mechanism 2 is connected to the guide frame assembly 2011. The guide frame assembly 2011 fixes the sliding mechanism 3. The sliding mechanism 3, together with the servo motor B301, the base plate assembly 3011, the guide rail assembly 3012, the clamping push rod 3013, the moving assembly 3014 and the clamping assembly 3016, realizes the gripping, repositioning and placement of the workpiece, and completes the core action of automatic material changing.

[0030] See Figures 1-5 The outer side of the guide rail mechanism 1 is fixedly connected to two mounting plates 101 facing each other, and the mounting plates 101 have mounting holes 1011 inside.

[0031] By setting an mounting plate 101 and opening mounting holes 1011 on the outside of the guide rail mechanism 1, it is easy to install the entire automatic material changing device on the vertical machining center, providing a mounting foundation for the device and ensuring its stable operation.

[0032] See Figures 2-4 The guide rail mechanism 1 has a transverse groove inside, and a partition assembly 1012 is fixedly connected inside the transverse groove. A servo motor A1013 is installed on the left side of the partition assembly 1012.

[0033] The guide rail mechanism 1 is equipped with a partition assembly 1012 and a servo motor A1013. The partition assembly 1012 can separate and support the internal structure, and the servo motor A1013 provides the power source for the movement of the displacement mechanism 2.

[0034] See Figures 5-6The right output shaft of the servo motor A1013 is equipped with a transmission screw 1014 via a coupling, and the displacement mechanism 2 has a screw hole inside that matches the transmission screw 1014.

[0035] By using the servo motor A1013 to engage with the screw hole of the displacement mechanism 2 through the transmission screw 1014, the rotational motion of the servo motor A1013 is converted into the linear motion of the displacement mechanism 2, thereby achieving precise lateral displacement of the displacement mechanism 2 within the guide rail mechanism 1.

[0036] See Figures 1-2 The displacement mechanism 2 has two protruding slider assemblies 201 fixedly connected to each other on both the front and rear sides.

[0037] The sliding of the slider assemblies 201 on the front and rear sides of the displacement mechanism 2 within the transverse groove of the guide rail mechanism 1 enhances the stability and guidance of the displacement mechanism 2 during movement, ensuring that the displacement mechanism 2 moves smoothly along the predetermined trajectory.

[0038] See Figures 3-6 A longitudinally arranged drive push rod 2012 is fixedly connected to the inner side of the guide frame assembly 2011;

[0039] The sliding mechanism 3 is powered by the drive push rod 2012 inside the guide frame assembly 2011 to move vertically within the guide frame assembly 2011, so as to meet the needs of gripping and placing materials of different heights.

[0040] See Figures 1-2 The rear end face of the drive push rod 2012 is connected to the front end face of the sliding mechanism 3 and is used to drive the sliding mechanism 3 to move.

[0041] By connecting the rear end of the drive push rod 2012 to the front end of the sliding mechanism 3, the displacement of the sliding mechanism 3 is precisely driven, thereby achieving precise adjustment of the sliding mechanism 3 in the longitudinal direction and ensuring the height accuracy of material gripping and placement.

[0042] During operation, firstly, the guide rail mechanism 1 is installed in a suitable position on the vertical machining center through the mounting holes 1011 on the mounting plate 101 to complete the basic fixation of the equipment. At this time, the partition assembly 1012, servo motor A1013 and transmission screw 1014 inside the guide rail mechanism 1 are also installed. The displacement mechanism 2 is installed in the guide rail mechanism 1 through the screw holes inside that match the transmission screw 1014. The slider assemblies 201 on the front and rear sides of the displacement mechanism 2 are in the transverse groove of the guide rail mechanism 1 to provide guidance and stable support for the movement of the displacement mechanism 2.

[0043] When a material change operation is required, the servo motor A1013 is started, and its output shaft drives the transmission screw 1014 to rotate. Since the internal screw hole of the displacement mechanism 2 is engaged with the transmission screw 1014, the displacement mechanism 2 moves laterally along the transverse groove of the guide rail mechanism 1 under the rotation of the transmission screw 1014. During the displacement process, the slider assembly 201 slides in the transverse groove of the guide rail mechanism 1 to ensure that the displacement mechanism 2 moves smoothly, thereby driving the guide frame assembly 2011 fixedly connected at the front end to move to the designated position.

[0044] After the guide frame assembly 2011 moves into place, the drive push rod 2012 is activated. The rear end face of the drive push rod 2012 is connected to the front end face of the sliding mechanism 3. Under the action of the drive push rod 2012, the sliding mechanism 3 makes longitudinal displacement within the guide frame assembly 2011 and adjusts to a suitable height position to meet the gripping needs of materials of different heights.

[0045] After the sliding mechanism 3 is adjusted to the correct position, the servo motor B301 is started. Its top output shaft drives the base plate assembly 3011 to rotate, and the guide rail assembly 3012 at the top of the base plate assembly 3011 rotates accordingly. The clamping push rod 3013 inside the guide rail assembly 3012 also rotates together. When it rotates to the appropriate angle, the clamping push rod 3013 extends and pushes the moving assembly 3014 to move inward along the guide rail assembly 3012. The guide block assemblies 3015 on the front and rear sides of the moving assembly 3014 slide inside the guide rail assembly 3012 to ensure the smooth movement of the moving assembly 3014. The clamping assembly 3016 on the outside of the moving assembly 3014 gradually approaches and clamps the material during the movement. After clamping the material, the servo motor B301 reverses, driving the base plate assembly 3011 and the gripped material to rotate, changing the material to the area above the machining center's working area. Subsequently, the displacement mechanism 2 and the sliding mechanism 3 act again to accurately place the material at the machining position of the machining center, completing the material changing operation.

[0046] In summary, this device, by providing a guide rail mechanism 1, can achieve lateral displacement guidance for the displacement mechanism 2.

[0047] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
