Description

Technical Field

[0001] The utility model belongs to the technical field of lathes, and in particular relates to a slide box. Background Art

[0002] The slide box of a general CNC lathe or ordinary lathe is composed of a large slide, a middle slide and a small slide. The travel of the large slide and the middle slide are perpendicular to each other. The large slide controls the tool to feed along the X-axis direction, and the middle slide controls the tool to feed along the Y-axis direction.

[0003] However, in some special application scenarios, such as boring an inner groove in the inner hole of a workpiece, the tool used for boring the inner groove is a floating tool head. The floating tool head includes a tool rod in an outer sleeve and an internal push rod. The extension and retraction of the floating tool head requires pushing and pulling the push rod inside the tool along the X-axis direction. However, of the existing slide box, only the large slide can realize X-axis movement, and the large slide drives the entire tool to move along the X-axis direction. The middle slide cannot drive the push rod to move along the X-axis direction. Therefore, a new slide box is needed that can drive the tool rod and push rod of the tool to move along the X-axis direction respectively. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a slide box for solving the technical problem that the slide box in the prior art cannot respectively drive the tool rod and the push rod of the tool to move along the X-axis.

[0005] The utility model solves the above technical problems with the following technical solutions: a slide box, the slide box is arranged on a frame, the slide box is connected to the frame through a slide rail, and comprises:

[0006] The slide box is provided with a first chamber, a second chamber and a third chamber in sequence, and the slide box is also provided with a first drive assembly and a second drive assembly;

[0007] The first drive assembly is disposed in the slide box, and the first drive assembly passes through the first chamber, the second chamber, and the third chamber;

[0008] The second driving assembly is arranged at the bottom of the slide box and is connected to the frame.

[0009] The utility model comprises a first driving assembly and a second driving assembly. The first driving assembly passes through a slide box and can be connected with a tool, thereby achieving the purpose of controlling the tool to move forward and backward, while the second driving assembly controls the slide box to move forward and backward.

[0010] Further: the first driving component includes:

[0018] A ball screw, wherein the screw of the ball screw is arranged between the slide rails, one end of the screw is connected to the output shaft of the second drive motor, and the ball nut of the ball screw is arranged at the bottom of the slide box.

[0019] The beneficial effect of adopting this step is that the second drive motor drives the lead screw to rotate, the lead screw converts its own rotational motion into the linear motion of the ball nut, and the ball nut drives the slide box to move axially along the lead screw.

[0025] The second transmission shaft is also provided with an air inlet hole in the radial direction, and the air inlet hole penetrates the blind hole.

[0026] The beneficial effect of adopting this step is that the second transmission shaft uses the air inlet hole and the blind hole as an integral air injection hole, and utilizes the positional relationship between the second transmission shaft and the tool to inject compressed gas into the tool from the air injection hole.

[0027] The beneficial effects of the utility model are:
