Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a saddle for a numerical control machine tool. Background Art

[0002] The saddle is a tool used to fix the material being processed on the machine tool. As a part of the machine tool, the saddle plays an important role when the machine tool is working. It fixes the material being processed and ensures that the processing position is not changed, making it convenient for people to process the material.

[0003] However, in the prior art, the surface of the existing saddle for CNC machine tools only has a processing table. Coolant is required for cooling during the processing, and the generated debris is discharged into the saddle. The debris is easy to adhere to the driving screw and may jam the driving parts, affecting the processing accuracy. If the debris and coolant are accumulated in the saddle for a long time, it is easy to affect the performance stability of the machine tool. Manual cleaning is often required, which is troublesome. In addition, the mixture of debris and coolant needs to be separated twice and cannot be discharged directly, which is time-consuming and labor-intensive. Utility Model Content

The sliding block is restricted by the limit block and slides on the inner wall of the shell until the clamping block at the top fixes the workpiece to prevent the workpiece from moving during subsequent fixation.

[0020] The outer wall of the sliding block 601 is slidably connected to the inner wall of the housing 1, the inner wall of the sliding block 601 is threadedly connected to the outer wall of the bidirectional screw 4, and the outer wall of the rubber block 605 is slidably connected to the outer wall of the bidirectional screw 4. During the movement of the sliding block 601, the rubber block 605 fixedly connected to the swivel 604 slides in the outer wall groove of the bidirectional screw 4 through the rotation of the swivel 604 connected to the outer wall, thereby cleaning the debris attached to the bidirectional screw 4.

[0021] The outer wall of the limit block 603 is slidably connected to the inner wall of the housing 1. The end of the limit block 603 away from the sliding block 601 penetrates the housing 1 and extends to the outside of the housing 1. The outer wall of the housing 1 is fixedly connected with a measuring ruler 8, and the top of the housing 1 is provided with a mounting hole 7. Through the threaded connection between the inner wall of the sliding block 601 and the outer wall of the bidirectional screw 4, the sliding block 601 slides on the inner wall of the housing 1 under the restriction of the fixedly connected limit block 603 until the clamping block 602 fixedly connected at the top fixes the workpiece to prevent the workpiece from moving during subsequent fixing. At this time, the bolt is installed into the mounting hole 7 to fix the workpiece.

[0022] The cleaning mechanism 9 includes a cleaning groove 904, a blocking block 905 is fixedly connected to the inner wall of the cleaning groove 904, a filter plate 901 is fixedly connected to the inner wall of the blocking block 905, oblique blocks 902 are symmetrically fixedly connected to both ends of the filter plate 901, and an external pipe 903 is arranged at the bottom end of the filter plate 901.

[0024] Working principle:

[0025] When in use, the mounting rail 2 at the bottom end of the housing 1 is mounted on the machine tool operating table, and the driving screw is installed into the screw groove 3, so that when the screw is driven to rotate, the housing 1 moves on the machine tool operating table through the mounting rail 2. At this time, the workpiece is placed on the top of the housing 1. Through the fixing mechanism 6, when the servo motor 5 drives the bidirectional screw 4 to rotate, the sliding block 601 is threadedly connected with the bidirectional screw 4, so that the sliding block 601 slides on the inner wall of the housing 1 under the restriction of the limit block 603 until the clamping block 602 at the top fixes the workpiece to prevent the workpiece from moving during subsequent fixing. At this time, the bolt is installed into the mounting hole 7 to fix the workpiece. Through the sliding of the limit block 603, the length data of the workpiece is observed through the measuring ruler 8. In the movement process of the sliding block 601, through the rotation of the swivel 604, the rubber block 605 on the swivel 604 slides in the groove of the bidirectional screw 4, so as to clean the debris attached to the bidirectional screw 4.

[0026] During the processing, the coolant and debris generated by the processing fall onto the filter plate 901 through the cleaning mechanism 9. The coolant passes through the filter plate 901 and falls onto the inclined block 902 below. Through the inclined setting of the inclined block 902, it finally flows into the middle of the two inclined blocks 902 and is discharged through the external pipe 903, which can be recycled. The generated debris is blocked by the filter plate 901. When the sliding block 601 moves, the curved surface design of the sliding block 601 pushes the debris to the two ends of the sliding block 601 and enters the cleaning groove 904. Through the inclined design of the blocking block 905, the coolant will not flow out of the cleaning groove 904. As the debris accumulates on the blocking block 905, it is finally discharged from the shell 1 through the cleaning groove 904.
