[0020] See also Figure 1-3 The utility model provides an embodiment: a bar cutting device for milling cutter processing, comprising a cutting groove 1 and a movable seat 2 horizontally movably arranged inside the cutting groove 1 by a first linear drive mechanism 3. The cutting groove 1 is specifically a rectangular structure with an open top. The first linear drive mechanism 3 includes a screw rod, a guide rod and a motor that drives the screw rod to rotate in parallel on both sides of the width direction of the cutting groove 1. One side of the movable seat 2 is threadedly connected to the screw rod, and the other side is slidably connected to the guide rod. The movable seat 2 is driven by the first linear drive mechanism 3 to slide horizontally inside the cutting groove 1. A first clamping mechanism 4 and a third clamping mechanism 9 are respectively provided on both sides of the driving direction of the first linear drive mechanism 3 inside the cutting groove 1, which are used to clamp and fix the two ends of the length of the bar to be cut. A bracket 201 is fixed to the top of the movable seat 2, and a feeding hole 202 is provided on the bracket 201 to accommodate the horizontal passage of the bar. A second clamping mechanism 5 and a cutting machine 6 are respectively provided on both sides of the bracket 201 along the moving direction of the first linear drive mechanism 3. The cutting machine 6 specifically includes a blade and a motor for driving the blade to rotate. A second linear drive mechanism 7 for adjusting the height of the cutting machine 6 is provided on the bracket 201. When working, the movable seat 2 is driven to move horizontally by the first linear drive mechanism 3, and then the cutting machine 6 is driven to move horizontally. The second linear drive mechanism 7 drives the cutting machine 6 to move downward, so that the bar can be cut into the required length as needed. In this embodiment, the second linear drive mechanism 7 is an electric push rod or a cylinder, etc., which is vertically installed at the top of the bracket 201, and its output end is fixedly connected to the cutting machine 6.

[0021] In this embodiment, the second clamping mechanism 5 includes a first clamping member 501 and a second clamping member 502 that are opposite to each other in the upper and lower directions, and a linear driving member 503 for adjusting the distance between the two. The linear driving member 503 can be specifically an electric push rod or a cylinder, etc., which is vertically installed at the bottom end of the bracket 201, and its output end is fixedly connected to the top end of the second clamping member 502. The second clamping member 502 is driven up and down by the extension and contraction of the linear driving member 503, and can clamp and fix rods of different sizes. When the rod needs to be cut into multiple sections, the second clamping mechanism 5 can cooperate with the first clamping mechanism 4 or the third clamping mechanism 9 to clamp and fix the rod, thereby improving the cutting accuracy.

[0022] In this embodiment, the opposite side of the first clamping member 501 and the second clamping member 502 is an arc-shaped surface, and rollers are provided on the inner side wall of the arc-shaped surface, which can reduce friction when the bar slides back and forth between the first clamping member 501 and the second clamping member 502.

[0023] In this embodiment, the first clamping mechanism 4, the third clamping mechanism 9 and the second clamping mechanism 5 have the same structure, and all include upper and lower clamping parts and an electric push rod, a cylinder or a manually adjusted threaded rod for adjusting the distance between the two, which can clamp and fix the two ends of the bar.

[0024] In this embodiment, a plurality of filter holes 101 are provided through the bottom end of the cutting groove 1, and a chip collecting groove 8 is provided below the cutting groove 1 so that metal debris generated by cutting can enter the chip collecting groove 8 through the filter holes 101. A chute adapted to the chip collecting groove 8 is provided at the bottom end of the cutting groove 1, so that the chip collecting groove 8 can be pulled out to process the collected metal debris. Furthermore, the bottom end of the movable seat 2 is tightly fitted with the bottom end of the interior of the cutting groove 1. When the movable seat 2 slides horizontally within the cutting groove 1, it can push the metal debris to slide inside, making it easier to enter the chip collecting groove 8 through the filter holes 101. Furthermore, a cleaning brush can also be provided at the bottom end of the movable seat 2 for better cleaning effect.

[0025] Working principle: When in use, the two ends of the bar are clamped and fixed by the first clamping mechanism 4 and the third clamping mechanism 9, and the movable seat 2 is driven to move back and forth along the length direction of the bar by the first linear drive mechanism 3. The second linear drive mechanism 7 drives the cutting machine 6 to move downward to cut the bar into the required length. When multiple cuttings are required, the movable seat 2 is driven horizontally by the first linear drive mechanism 3 until a free end of the bar away from the first clamping mechanism 4 or the third clamping mechanism 9 passes through the feed hole 202 and is clamped and fixed by the second clamping mechanism 5. This can provide support during cutting and improve cutting accuracy. The cut bar falls directly into the inside of the cutting groove 1, and metal debris enters the inside of the chip collecting groove 8 through the filter hole 101 for easy collection and processing.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
