DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be an intermediate component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be an intermediate component.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] refer to Figure 1 In one embodiment of the present application, a dual-hole step difference measurement device is disclosed. A platform 5 serves as a carrier, and a first measurement station 2, a second measurement station 3, and a movable mechanism 4 are disposed on the platform 5. The first measurement station 2 and the second measurement station 3 are respectively used to place and position a workpiece. A probe 1 is connected to the movable mechanism 4, which drives the probe 1 to move above the first measurement station 2 and the second measurement station 3 to measure the step difference of the workpiece located on the first measurement station 2 and the second measurement station 3.

[0026] To ensure the accuracy of the probe measurement, the movable mechanism 4 needs to maintain a constant relative height to the first measuring station 2 and the second measuring station 3 when the probe 1 is moved. At the same time, the first measuring station 2 and the second measuring station 3 are kept in a horizontal state to facilitate detection.

[0027] refer to Figure 2A horizontal base 51 is provided on the machine platform 5, and the first measuring station 2 and the second measuring station 3 are arranged on the horizontal base 51 so that the workpiece on the horizontal base 51 can be kept horizontal.

[0028] The movable mechanism 4 drives the probe 1 to move above the horizontal base 51 and parallel to the horizontal base 51 .

[0029] In some embodiments, the movable mechanism 4 can be moved by two sets of linear modules cooperating with each other. Figure 3 As shown in the figure, the movable mechanism 4 includes an X-axis moving module 41 and a Y-axis moving module 42. The X-axis moving module 41 is arranged on the machine table 5, and the Y-axis moving module 42 is arranged on the X-axis moving module 41 and moves with the X-axis moving module 41. A robotic arm 43 is connected to the Y-axis moving module 42, and the robotic arm 43 is used to connect to the probe 1 and move with the Y-axis moving module 42.

[0030] The first measuring station 2 has the same structure as the second measuring station 3. Take the first measuring station 2 as an example, refer to Figure 2 In some embodiments, the first measuring station 2 includes a first clamping assembly formed by a positioning block 21 and a cylinder 22. The cylinder 22 has a tendency to move toward the positioning block 21, and is used to cooperate with the positioning block 21 to tighten the workpiece and push the workpiece to fit with the positioning block 21 to complete the positioning.

[0031] Furthermore, the first measuring station 2 also includes a second clamping assembly. The second clamping assembly has the same structure as the first clamping assembly and also includes a positioning block for positioning the workpiece and a cylinder for pushing the workpiece toward the positioning block.

[0032] Furthermore, the clamping direction of the second clamping assembly on the workpiece is perpendicular to the clamping direction of the first clamping assembly on the workpiece, and the workpiece is pushed along the surface of the horizontal base 51 from two perpendicular directions to be positioned and fixed.

[0033] In some embodiments, reference Figure 4 A first scanning device 52 and a second scanning device 53 are provided on the horizontal base 51. The first scanning device 52 is provided corresponding to the first measuring station 2, and the second scanning device 53 is provided corresponding to the second measuring station 3. The first scanning device 52 and the second scanning device 53 are used to detect whether the workpiece has been pushed into place and reached the positioning position.

[0034] Further, such as Figure 4 As shown, in order to avoid the first scanning device 52 so that it can scan the workpiece smoothly, the first clamping assembly is provided with an avoidance opening 211 on the positioning block 21 for avoiding the first scanning device 52 .

[0035] Furthermore, in the above embodiment, the first measuring station 2 and the second measuring station 3 can be used to measure both the front and back sides of the same workpiece by flipping the workpiece.

[0036] To facilitate the adjustment of the probe 1 and prevent the probe 1 from interfering with the workpiece in the horizontal direction during movement, a clamping member 44 is provided on the robotic arm 43. The clamping member 44 is used to connect the probe 1. The relative height between the probe 1 and the horizontal base 51 can be manually adjusted by adjusting the tightness of the clamping member 44.

[0037] One end of the robotic arm 43 is connected to the Y-axis moving module 42 , and the clamping component 44 is located at an end away from the Y-axis moving module 42 .

[0038] The technical features of the above-described embodiments may be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as no contradiction exists between these combinations of technical features, they should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be deemed that the drawing also discloses examples of combinations of the various embodiments involved.

[0039] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person skilled in the art may make various modifications and improvements without departing from the spirit of the present application, and such modifications and improvements are all within the scope of protection of the present application.
