[0030] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0031] Please refer to Figure 1-Figure 4 The utility model discloses a processing and positioning fixture for a milling machine column, comprising:

[0032] A mounting frame 100, wherein the mounting frame 100 is provided with a slide rail 110 along its length direction;

[0033] A plurality of positioning assemblies 200, each of which comprises two support units 210 slidably disposed on the slide rail 110, and a clamping block 220 disposed between the two support units 210 and slidable along the slide rail 110, wherein the support unit 210 comprises a support block 212 abutting against the bottom surface of the milling machine column 300, and the clamping block 220 can move in a height direction and abut against the top surface of the milling machine column 300.

[0034] In the present application, multiple positioning assemblies 200 are slidably arranged on the mounting frame 100, so that each positioning assembly 200 can slide along the slide rail 110 to adjust the distance between the multiple positioning assemblies 200, and thus can clamp the columns 300 of different lengths. At the same time, by sliding the positioning assembly 200, the positioning assembly 200 can clamp the middle of the cut portion to prevent the column 300 from being separated from the positioning assembly 200 under its own gravity after the column 300 is cut.

[0035] Specifically, one or more positioning components 200 are slid to determine the distance between the multiple positioning components 200 to accommodate columns 300 of different lengths, and then the column 300 is placed on the support block 212, and the clamping block 220 is pressed downward against the upper surface of the column 300 to clamp the column 300.

[0036] It should be mentioned that the present application sets a clamping block 220 between the two support blocks 212. The same clamping block 220 can clamp two adjacent columns 300 to achieve batch clamping and improve the clamping efficiency.

[0037] Furthermore, the support unit 210 further includes:

[0038] A mounting block 211 slidably disposed on the slide rail 110;

[0039] A fixed clamp block 214 and a sliding clamp block 213, wherein the fixed clamp block 214 is fixedly connected to the mounting block 211, and the sliding clamp block 213 is arranged on the mounting block 211 and can move in a direction toward or away from the fixed clamp block 214 to clamp or release the two sides of the milling machine column 300; the support block 212 is fixedly arranged on the mounting block 211 and is located between the fixed clamp block 214 and the sliding clamp block 213.

[0040] A slidable mounting block 211 is arranged on a slide rail 110, and a fixed clamp block 214 and a sliding clamp block 213 are arranged on the mounting block 211. The sliding clamp block 213 moves toward the fixed clamp block 214, so that the fixed clamp block 214 and the sliding clamp block 213 can respectively clamp the two sides of the column 300, thereby realizing the lateral positioning of the column 300.

[0041] Furthermore, each of the mounting blocks 211 is provided with two fixed clamping blocks 214 and two sliding clamping blocks 213 , and a positioning protrusion 215 is provided at the end of the fixed clamping block 214 , and the positioning protrusion 215 can abut against the end of the milling machine column 300 .

[0042] Two fixed clamping blocks 214 and two sliding clamping blocks 213 are simultaneously arranged on the same mounting block 211 , so that each mounting block 211 can clamp at least two columns 300 , and the two columns 300 are pressed by a pressing block 220 .

[0043] A positioning protrusion 215 is provided at the end of the fixing clamp block 214 so that the positioning protrusion abuts against the end of the column 300 , so as to realize the end positioning of the column 300 .

[0044] Furthermore, two first driving cylinders 216 are provided on the mounting block 211 to respectively drive the two sliding clamping blocks 213 to slide.

[0045] Furthermore, both ends of the pressing block 220 are bent downward to form a pressing portion 221 , and the two pressing portions 221 can abut against the top surfaces of two adjacent milling machine columns 300 at the same time.

[0046] Furthermore, a slider 234 is provided between two adjacent support units 210, and the slider 234 can slide along the slide rail 110. A second driving cylinder 230 that can be extended and retracted along the height direction is provided on the slider 234. The second driving cylinder 230 includes a cylinder body 231 and a telescopic rod 232, and the telescopic rod 232 is detachably connected to the clamping block 220.

[0047] Specifically, the expansion and contraction of the telescopic rod 232 drives the pressing block 220 to move downward or upward to achieve compression or release of the column 300. At the same time, since the second driving cylinder 230 is disposed on the slider 234, the second driving cylinder 230 can also slide along the slide rail 110 to the center position of two adjacent columns 300, thereby making the distance between the pressing block 220 and the two adjacent columns 300 equal, and the force of the pressing block 220 on the two columns 300 is more uniform.

[0048] Furthermore, the side wall of the pressing block 220 is recessed inward to form a groove;

[0049] A pulling column 233 is fixedly connected to one end of the telescopic rod 232 away from the cylinder body 231. The telescopic rod 232 can be extended into the groove and rotate and slide relative to the clamping block 220. The telescopic rod 232 moves in the height direction to make the pulling column 233 abut against the top surface of the clamping block 220.

[0050] Specifically, before installing the column 300, the clamping block 220 is not installed on the telescopic rod 232, or is rotated to a position parallel to the column 300 to make room for installing the column 300 and avoid positional interference between the column 300 and the clamping block 220; after installing the column 300, the clamping block 220 is installed, or the clamping block 220 is rotated to an angle perpendicular to the column 300 so that the two ends of the clamping block 220 are respectively above the two columns 300, and the telescopic rod 232 is driven by the second driving cylinder 230 to pull the clamping block 220 downward to clamp the two columns 300 at the same time.

[0051] Furthermore, two positioning assemblies 200 are disposed on the slide rail 110 , and each positioning assembly 200 is located at two ends of the milling machine column 300 .

[0052] Specifically, a positioning assembly 200 is respectively provided at both ends of the column 300, so that the two support units 210 in the same positioning assembly 200 clamp the ends of the column 300 at the same time, which is suitable for the situation where the column 300 needs to be cut, so as to enhance its clamping force on the column 300, and it is not easy to separate from the positioning assembly 200 after cutting.

[0053] Furthermore, two positioning assemblies 200 are disposed on the slide rail 110 , and four supporting units 210 are evenly arranged along the length direction of the milling machine column 300 .

[0054] The four support units 210 are arranged equidistantly along the length direction of the column 300, which is suitable for surface processing and other situations where cutting is not required. It can make the force at various positions on the column 300 more uniform and avoid bending of the column 300 due to excessive force during processing.

[0055] Furthermore, a plurality of slide rails 110 are provided along the width direction of the mounting frame 100 , and a plurality of the positioning assemblies 200 are disposed on each of the slide rails 110 .

[0056] A plurality of slide rails 110 are provided, and a plurality of positioning assemblies 200 are provided on each slide rail 110 , so as to realize batch clamping and batch processing of the columns 300 .
