Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a material chip separation mechanism for numerically controlled lathes. Background Art

[0002] CNC lathe is one of the most widely used CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disk parts, inner and outer conical surfaces of arbitrary taper angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads. It can also perform grooving, drilling, reaming, reaming and boring, etc. It can automatically process the parts according to the pre-compiled processing program. Compared with ordinary machine tools operated by hand, it has the advantages of high precision and high efficiency. However, due to the high processing efficiency, the operator generally does not intervene during the processing, which causes the finished parts to be mixed with the turning debris, and then they are manually separated, which affects production efficiency and increases labor costs. In addition, the edges of the turning debris are often sharp and can easily cause injuries. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 3 As shown, the utility model provides a chip separation mechanism for a CNC lathe, including a fixed seat 1, which is installed on a workbench below the spindle clamp of the lathe, a material receiving box 2 is fixed on the fixed seat 1, a rebound baffle 3 is rotatably connected to the top of the material receiving box 2, a feeding chute 4 is opened at the bottom of the material receiving box 2, and a finished product collection box 5 is installed at the outlet of the feeding chute 4.

[0022] refer to Figure 1 and Figure 2 The baffle panel 301 is installed on the inner top of the material receiving box 2, and the connecting piece at one end of the baffle panel 301 is sleeved on the rotating shaft 302. The rotating shaft 302 is rotatably connected to the top of the inner wall of the material receiving box 2. A rebound spring 303 is sleeved on the rotating shaft 302. The two pins of the rebound spring 303 are respectively attached to the bottom of the baffle panel 301 and the inner wall of one side of the material receiving box 2 connected to the rotating shaft 302. The rotating shaft 302 is installed on the top of the side wall of the material receiving box 2 which is consistent with the feeding direction of the lathe.

[0023] By installing a baffle panel 301 on the top of the material receiving box 2 and a rebound spring 303 under the baffle panel 301, when the finished material is processed on the lathe, the debris generated is relatively light, and the force generated by the fall does not meet the minimum requirement for the baffle panel 301 to sink, and the debris will not fall into the material receiving box 2. After the finished parts are processed, the finished parts fall on the baffle panel 301, and the force generated by the heavier fall of the finished parts meets the rotation requirement of the baffle panel 301. The baffle panel 301 opens, and the finished parts fall into the material receiving box 2, thereby realizing automatic separation of material chips.

[0024] refer to Figure 1A plurality of fans 6 are installed on the top of the outer side of the receiving box 2 . The fans 6 are fixed to the outer side of the side wall of the receiving box 2 connected to the rotating shaft 302 . The air outlets of the fans 6 are perpendicular to the rotating shaft 302 .

[0025] By installing the fan 6 with the air outlet perpendicular to the rotating shaft 302, the fan 6 will blow away the debris that falls on the surface of the baffle panel 301 during the processing of the finished material, keeping the surface of the baffle panel 301 clean, so that there is no debris on the baffle panel 301 when the finished product falls, and further separate the material chips.

[0026] refer to Figure 1 , Figure 2 and Figure 3 The outer surface of the material receiving box 2 and the upper surface of the rebound baffle 3 are coated with an anti-static adsorption coating 202.

[0027] By applying an anti-static adsorption coating 202 on the outer surface of the material receiving box 2 and the upper surface of the rebound baffle 3, the fine debris generated during the turning process of the finished parts will not be adsorbed on the outer surface of the material receiving box 2 and the rebound baffle 3 due to static electricity, and can be easily blown away by the fan 6, thereby reducing the probability of debris being mixed in the finished parts and further separating the chips.

[0028] How to use

[0029] The working principle and use process of the utility model are as follows: when the lathe is turning shaft parts, turning produces debris of different sizes, which falls on the material collection box 2. Due to its light weight, the baffle panel 301 cannot be opened and is then blown off the material collection box 2 by the fan 6. After the turning is completed, the finished parts fall on the material collection box 2, meeting the requirement of the baffle panel 301 rotating. The baffle panel 301 rotates downward around the rotating shaft 302. Since the installation direction of the rotating shaft 302 is consistent with the feeding direction of the lathe, the finished parts can roll downward along the baffle panel 301 and fall into the material collection box 2, and then roll down along the feeding slide 4 at the bottom of the material collection box 2 into the finished product collection box 5. When the finished materials fall into the material collection box 2, the baffle panel 301 is reset under the rebound force of the rebound spring 303, so that the stepped baffle 304 is closed under the limit plate 7, and this process is repeated to complete the separation of the finished materials and the debris.
