Description

Technical Field

[0001] The utility model relates to the technical field of lathe transfer, in particular to a transfer device for a floor-standing lathe. Background Art

[0002] The floor-standing lathe is also called a face lathe, end lathe, big head lathe or pit lathe. It is suitable for disc-shaped, annular workpieces or thin-walled cylindrical workpieces with large diameter, short length and light weight. Structural features: no bed, tailstock, no lead screw. The floor-standing lathe is also called a big head lathe. The floor-standing lathe is mainly used for turning heavy machinery parts with larger diameter, such as tire molds, large diameter flange tube plates, turbine accessories, heads, etc. It is widely used in the processing and manufacturing of petrochemical, heavy machinery, automobile manufacturing, mining, railway equipment and aviation components.

[0003] When a floor-standing lathe is transferred within the same workshop, a forklift is generally used to transfer the lathe. However, the load-bearing area of ​​some existing transfer devices is relatively fixed and generally small, and cannot be adjusted according to the size of the floor-standing lathe. The applicability is low and cannot better meet the transfer needs of the lathe. In addition, some existing floor-standing lathes have different shapes and volumes, and the weight of different positions of the same lathe is also different. Correspondingly, the gravity borne by different positions of the transfer device is also different. When the center is offset, the moving wheel on one side is subjected to greater force, which will make the overall movement of the device inconvenient. When the existing transfer device is moving, it is impossible to adjust the position of the support point according to the gravity it is subjected to, which is inconvenient to transfer the lathe and the use effect is poor.

When carrying a larger floor-standing lathe, the moving plate 4 on one side is pulled outward, and the gear 61 is rotated through the meshing transmission of the first rack plate 62 and the gear 61. At the same time, the meshing transmission of the gear 61 and the second rack plate 63 drives the moving plate 4 on the other side to move in the opposite direction. After moving, the moving plate 4 is positioned by the positioning rod 7, so as to increase the bearing area of ​​the device, which is convenient for transferring floor-standing lathes of different volumes. It has high applicability and is simple and easy to operate.

[0023] The guide mechanism 14 includes guide grooves 141 provided on both sides of the bottom of the fixing plate 2. The cross-sectional shape of the guide groove 141 is T-shaped. Guide blocks 142 are fixedly connected to both sides of the top of the mounting plate 13. The cross-sectional shape of the guide block 142 is consistent with that of the guide groove 141. The position of the guide block 142 corresponds to that of the guide groove 141. The guide block 142 is slidably connected to the inner wall of the guide groove 141.

[0024] Working principle: first, before loading the floor-standing lathe, flip the positioning rod 7 to disengage it from the positioning groove 8 and the through groove 9, then move the movable plate 4 on one side outward, and simultaneously engage the first rack plate 62 and the second rack plate 63 with the gear 61 for transmission, so that the movable plates 4 on both sides move in opposite directions at the same time, thereby expanding the load-bearing range of the device. After adjusting to the appropriate position, flip the positioning rod 7 in the opposite direction, so that the two ends extending from the positioning rod 7 are embedded in the positioning groove 8 and the through groove 9 corresponding to its position to position the movable plates 4 on both sides, and avoid the position of the movable plates 4 from changing. Then place the floor-standing lathe on top of the device. If one side of the lathe is heavier, the linear guide rail 12 can be used to control the mounting plate 13 to move toward the side with heavier weight, and at the same time, it can be guided by the guide mechanism 14 to increase the load-bearing capacity on the side with heavier weight, and then the control head 1 can be pulled to transfer.
