[0002] During the processing of bar materials on a numerical control machine tool, the bar materials need to be fixed in a chuck on a base slide table and clamped by a hydraulic chuck. For this feeding process, the existing conventional method may lift the bar materials through multiple personnel or auxiliary equipment to make them in a horizontal state, and then fix the bar materials in the chucks at both ends by moving. If the bar materials are not in a horizontal position, some jaws in the chuck fixed at one end will be damaged due to unbalanced force.

[0016] To describe in detail the technical solutions disclosed by the present utility model, the following further introduction is made in conjunction with the attached drawings of the specification.

[0017] Combined with Figures 1-3 As shown, the present utility model provides a loading auxiliary device for a numerically controlled machine tool, which is used for the auxiliary fixation of a bar stock in the chuck of a clamping seat. The device is arranged on the slide table of the machine tool base and is located between two spindle clamping seats. The two spindle clamping seats are used to clamp both ends of the bar stock for subsequent cutting and other processing operations.

[0018] The device described in the present utility model includes a base 1. A sliding groove can be provided at the bottom of the base 1 to achieve adaptive movement on the machine tool according to the length of the bar stock. The device also includes two parts respectively located at both ends of the bar stock. The base 1 is fixedly connected with a mounting base 2. It can be combined with Figure 3In the structure shown, the mounting base 2 is fixed by bolts, and the bolts are located in the U-shaped notch on the mounting base 2. The mounting base 2 and the driving mechanism 7 are integrated into a module for easy assembly. The driving mechanism 7 can be selected from a cylinder, an electric cylinder or a hydraulic cylinder. In this embodiment, a cylinder is taken as an example. The cylinder is located in the middle of the mounting base 2, and the mounting base 2 can wrap around the cylinder. The side wall of the cylinder can be fixed to the mounting base 2 by screws. The telescopic rod of the cylinder 2 is set upward and connected to the bottom of the guide wheel bracket 4 to control the up and down movement of the guide wheel bracket 4. The guide wheel bracket 4 is installed with a guide wheel 5 through a bearing 6. The guide wheel 5 has a structure as shown in the figure, including two opposite conical surfaces for supporting the bar material. The groove on the guide wheel 5 is used to cater to different bar material thicknesses, and different guide wheels 5 can be set for bars of different thicknesses. It is pointed out here that the guide wheel 5 and the guide wheel bracket 4 are combined into a module, and it is more convenient to replace them as a whole. The important thing is that the guide wheel bracket 4 does not need to be fastened with fixing bolts. The telescopic rod connected to the bottom only needs a support block to prevent it from falling. The guide wheel bracket 4 can be directly removed upward to complete the replacement.

[0019] It is further pointed out that in order to improve the lifting stability of the guide wheel bracket 4, through holes are provided on the two mounting columns 201 of the mounting seat 2 for the installation of the guide column 3, and the installation structure can be inserted and pulled out. Furthermore, grease can be provided for lubrication. The guide column 3 is fixed to the guide wheel bracket 4 by threaded connection, and can be pulled upward together with the guide wheel bracket 4. The guide column 3 is located on two opposite sides, and there are limit columns 8 and limit blocks 9 on both sides. The limit columns 8 are opposite to the fixed ends of the guide columns 3, and are fixed at the bottom and fixed on the base 1. The limit blocks 9 are used to fix and prevent the guide wheel bracket 4 from falling when it rises to the required height on the drive of the cylinder. The limit blocks 9 can also play the role of lower limit to prevent the cylinder from being constantly stressed. The limit blocks 9 support the guide wheel bracket 4 from the bottom and do not hinder the guide wheel bracket 4 from being pulled out upward to complete the replacement.

[0020] For the mounting base 2, the driving mechanism 7 fixed in the middle can adjust the height of the cylinder through the pad 202, and the driving mechanism 7 is further fixed with bolts. The utility model maximizes flexibility through multiple movable connection structures and components to meet the requirements of different bar thicknesses and support heights, and has good stability. For example, the bearing can be set as a damping bearing to avoid random and easy shaking.
