Description

Technical Field

[0001] The utility model relates to the technical field related to processing positioning, in particular to a processing positioning device of a gantry CNC milling machine. Background Art

[0002] A milling machine is a processing equipment used for plane cutting or grooving of workpieces. When the milling machine processes the workpiece, in order to ensure the placement stability of the workpiece during processing, a processing positioning device is used to fix the workpiece. There is currently a processing positioning device for a gantry CNC milling machine (application number: 202121151451.7). When the operator starts the telescopic rod, the telescopic rod uses the action of the movable frame to stably push the clamping plate to move, thereby realizing the clamping function of the material. By setting up motor No. 1, motor No. 1 can effectively use the action of the coupling to drive the rotating seat to rotate, thereby facilitating the operator to process the back side of the material.

[0003] The above-mentioned existence, although utilizing the rotation of rotating seat can turn over the workpiece, and switch its upper and lower end surfaces for processing, but the placement height of rotating seat is fixed, if the size of workpiece rotates, the circular track formed is larger than the distance between rotating seat and rotating plate, and it is not convenient to turn over the workpiece and rotate it for reverse processing.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1, reference Figures 1 to 5 A processing positioning device for a gantry CNC milling machine includes a placing table 1, on which a plurality of slide bars 2 are fixedly connected, and the plurality of slide bars 2 are respectively connected with two sets of blocks 3 for sliding movement, and the blocks 3 can be lifted and slid at the positions corresponding to the two sets of slide bars 2, and the two sets of blocks 3 are connected with push rods 4 for rotation through bearings, and the push rods 4 can rotate at the positions corresponding to the blocks 3, and the output ends of the two sets of push rods 4 are both provided with clamping plates 5, and the push rods 4 can drive the corresponding clamping plates 5 to rotate synchronously, and can also move the clamping plates 5 is moved horizontally, and when the workpiece is placed between the two groups of clamping plates 5, the two groups of clamping plates 5 can clamp and fix the workpiece. The two groups of push rods 4 are fixed with rod bodies 6. When the push rods 4 rotate, they can drive the rod bodies 6 and the rollers 7 to move synchronously. When the rod bodies 6 drive the rollers 7 to contact the placement table 1, the block 3, the push rods 4 and the clamping plates 5 are raised upward. The two groups of rod bodies 6 are connected to the rollers 7 through the connecting shaft. The two groups of rollers 7 fit the placement table 1, and the placement table 1 is connected by the connecting shaft. When the block 3 is lifted up, the spacing between the two corresponding groove wheels 9 is enlarged, and the transmission of the two groups of groove wheels 9 can still be guaranteed. When the two groups of push rods 4 rotate synchronously, they will drive the rod body 6 and the roller 7 to move on the placement table 1. At this time, the two groups of blocks 3 will move the rod body 6 upward. Later, when the rod body 6 moves to the other end for placement, the block 3 will fit on the placement table 1 again, and then cooperate with the push rod 4 to rotate at the block 3. When the two groups of clamps 5 drive the workpiece to turn over, as the rotation angle of the workpiece changes, the distance between the block 3 and the placement table 1 will gradually expand, which can ensure the circular trajectory of the workpiece when it rotates, and the placement table 1 will not hinder it, so it is convenient to turn the workpiece over and rotate it for reverse processing.

[0024] In this embodiment, first baffles 11 are fixedly connected at both corners of the placement table 1, and the first baffles 11 are used to intercept the debris generated by the workpiece from contacting the elastic band 10. A dual-axis motor 13 is installed on the placement table 1, and the model of the dual-axis motor 13 is selected according to actual work requirements. The two sets of output ends of the dual-axis motor 13 are respectively connected to the two sets of round rods 8. The dual-axis motor 13 cooperates with the transmission of the two sets of round rods 8, multiple sets of groove wheels 9 and two sets of elastic bands 10 to rotate the two sets of push rods 4 synchronously. A base 14 is fixedly connected to the four corners of the placement table 1, and a second baffle 12 is fixedly connected to the placement table 1. The second baffle 12 is used to intercept the debris generated by the workpiece from contacting the dual-axis motor 13. Rubber pads 15 are fixedly connected to the two sets of clamps 5. There are no obstacles at the end of the multiple sets of groove wheels 9 away from the placement table 1, so that the elastic band 10 at the groove wheel 9 moves toward the end away from the placement table 1 and can be removed for replacement.

[0025] The working principle of this embodiment is as follows: when in use, the workpiece is placed on the placement table 1 and between the two groups of clamping plates 5. After placement, the two groups of push rods 4 are connected to the external power supply and the driving device, and the two groups of push rods 4 can drive the two groups of clamping plates 5 to clamp and fix the workpiece. At this time, the external gantry CNC milling machine can perform milling processing on the workpiece. When the reverse side of the workpiece needs to be milled, the dual-axis motor 13 is connected to the external power supply and the driving device, and the dual-axis motor 13 can cooperate with the transmission of multiple groups of groove wheels 9 and two groups of elastic belts 10 to drive the two groups of push rods 4 to drive the clamping plates 5 and The rod body 6 rotates synchronously. At this time, when the rod body 6 and the corresponding roller 7 move on the placement table 1, the block 3 can be moved upward on the outer wall of the corresponding slide rod 2, and then the push rod 4 can drive the clamping plate 5 and the workpiece to rotate while moving upward. At this time, when the workpiece rotates, the problem of the circular trajectory of the workpiece being restricted by the placement table 1 can be avoided. At the same time, when the rod body 6 drives the roller 7 to move to the other end for placement, the block 3 is placed back on the placement table 1, and the workpiece is also turned over. The external gantry CNC milling machine can mill the reverse side of the workpiece.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
