Description

Technical Field

[0001] The utility model relates to the technical field of milling machining alignment, in particular to a milling auxiliary alignment device. Background Art

[0002] When milling a material, the workpiece needs to be placed on a specific workbench to be fixed and clamped before processing. Before processing, the milling cutter needs to be used to align the workpiece surface, that is, the milling cutter contacts the workpiece surface and determines the position and angle of the workpiece by cutting or scratching. This method can achieve accurate tool alignment to a certain extent.

[0003] However, the milling cutter will leave scratches on the workpiece surface during the tool setting process. These scratches will affect the surface quality of the workpiece and may even affect the machining accuracy of the workpiece, making it impossible to meet the surface requirements of the workpiece itself.

The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] See also Figures 1 to 3 , is a milling auxiliary alignment device of an embodiment of the utility model, comprising a carrier plate 10, a visual component 20 installed on one side of the carrier plate 10, and a height measuring component 30 installed on the other side of the carrier plate 10. The carrier plate 10 is used to connect a transmission tool such as a manipulator to drive the entire milling auxiliary alignment device to move to the position of the workpiece for auxiliary alignment.

[0027] The visual component 20 includes a bracket 21 installed on one side of the carrier plate 10 , a plurality of cameras 22 installed on one side of the bracket 21 , and a coaxial light source 23 coaxially installed at one end of each camera 22 .

[0028] The height measuring assembly 30 includes a fixed plate 31 installed on the side of the carrier plate 10 away from the bracket 21, a moving plate 32 slidably connected to the fixed plate 31, two first height measuring sensors 33 fixedly installed on one side of the top of the moving plate 32, two second height measuring sensors 34 detachably installed on the other side of the top of the moving plate 32, and a linear module 35 installed on one side of the fixed plate 31; the linear module 35 is used to drive the moving plate 32 to move along the length direction of the fixed plate 31. In this embodiment, the axis centerline direction of the first height measuring sensor 33 is consistent with the axis centerline direction of the second height measuring sensor 34, and the probe of the first height measuring sensor 33 is kept flush with the probe of the second height measuring sensor 34.

[0029] like Figure 3As shown, depressions 321 are evenly spaced on the top surface of the movable plate 32, and a plurality of assembly holes 322 are arrayed on the movable plate 32 corresponding to the inside of each depression 321. A transfer plate 341 is connected to one side of each second height measuring sensor 34, and a slot 342 is provided along the length direction of the transfer plate 341; wherein the transfer plate 341 is used to be embedded in the inside of the depression 321, and the slot 342 is used to correspond to the assembly hole 322. The second height measuring sensor 34 can be detachably connected to the movable plate 32 by passing a bolt through the slot 342 and matching with the inside of the assembly hole 322.

[0030] In actual use, the camera 22 is first used to approach the workpiece. The camera 22 captures a certain feature on the surface of the workpiece (the center or corner of the workpiece, etc.) as a marking position. The system uses the marking position as the reference origin to establish an XY coordinate system on the surface of the workpiece, and then moves the camera 22 to the processing position to obtain the two-dimensional coordinates of the processing position. Next, the first height sensor 33 and the second height sensor 34 are used to contact the surface of the workpiece to measure the height change between the processing position and the marking position, and determine the height in the Z-axis direction. At this time, the three-dimensional coordinates of the processing position can be obtained. The three-dimensional coordinates of the processing position are uploaded to the system, and the milling cutter can be guided to the processing position for processing. Compared with the traditional tool setting method, the utility model uses the camera 22 in combination with the first height sensor 33 and the second height sensor 34 to obtain the three-dimensional coordinates of the processing position, which can assist in obtaining the precise cutting position of the milling cutter, eliminate the contact between the milling cutter and the surface of the workpiece, avoid scratches, and effectively ensure the processing accuracy and surface requirements of the workpiece.

[0031] It can be understood that the distance between the first height sensor 33 and the second height sensor 34 can be flexibly adjusted according to the surface conditions of different workpieces, and the distance between the two second height sensors 34 can also be flexibly adjusted, which greatly improves the overall flexibility and versatility.

[0032] Specifically, two opposite sides of the movable plate 32 are slidably connected to the fixed plate 31 via guide rail pairs 36 .

[0033] In this embodiment, the moving direction of the moving plate 32 is consistent with the axis direction of the first height measuring sensor 33 , and the axis direction of the first height measuring sensor 33 is consistent with the axis direction of the camera 22 .

[0034] The above-mentioned milling auxiliary alignment device has a simple structure and is easy to use. It uses the camera 22 to capture the displacement of the marking position and the processing position, and cooperates with the first height measuring sensor 33 and the second height measuring sensor 34 to measure the height change between the processing position and the marking position. It can assist in obtaining the precise cutting position of the milling cutter, eliminate the surface contact between the milling cutter and the workpiece, avoid scratches, and effectively ensure the processing accuracy and surface requirements of the workpiece.

[0035] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
