Detailed Implementation

[0025] Example 1, please refer to Figures 1 to 4 This is a schematic diagram of a step difference circumferential measurement device provided by this utility model. The step difference circumferential measurement device includes a machine base 10; an installation platform 20 disposed on the machine base 10; a product positioning frame 21 disposed on the installation platform 20; a horizontal drive component 30; and a measurement component 40 disposed on the horizontal drive component 30. It is conceivable that this step difference circumferential measurement device also includes other functional components and specific structures, such as electrical connection components, control components, installation structures, etc., which are all technologies known to those skilled in the art, and therefore will not be described in detail here.

[0026] The machine base 10 serves as an installation carrier, facilitating the assembly and installation of various components and the setting of height.

[0027] In this embodiment, the installation platform 20 is a rectangular plate. Height adjustment blocks 11 are provided at the bottom of the four corners of the installation platform 20 and are connected by a threaded structure. The height adjustment blocks 11 are connecting plate structures of different heights. By padding the bottom of the installation platform 20, the upper part of the installation platform 20 is flat, avoiding the influence of the ground environment.

[0028] In this embodiment, a product positioning frame 21 is provided at the upper end of the installation platform 20. When the product has a flat structure, a multi-end clamping method can be used. When the product positioning frame 21 has an irregular structure, a contour positioning method can be used.

[0029] In this embodiment, the horizontal drive assembly 30 includes a transverse guide rail 31 arranged along the width direction of the mounting platform 20, a transverse slider 32 slidably arranged on the transverse guide rail 31, and a transverse drive module 33 connected to the transverse slider 32. The transverse drive module 33 is a motor. There are two transverse guide rails 31, one of which is integrated with the transverse drive module 33. The transverse drive module 33 drives the transverse slider 32 to move along the transverse guide rail 31 to achieve the purpose of quickly approaching the product positioning frame 21.

[0030] A longitudinal guide rail 34 is provided on the transverse slider 32 along the length of the mounting platform 20. A longitudinal slider 35 is slidably arranged on the longitudinal guide rail 34. The longitudinal slider 35 is connected to a longitudinal drive module 36, which is a motor. There is one longitudinal guide rail 34, which is integrated with the longitudinal drive module 36. The longitudinal drive module 36 drives the longitudinal slider 35 to move along the longitudinal guide rail 34, thereby adjusting the initial position of the measuring component 40 corresponding to the product positioning frame 21.

[0031] In this embodiment, drag chains 37 connecting the horizontal slider 32 and the vertical slider 35 are respectively provided on the horizontal guide rail 31 and the vertical guide rail 34. The drag chains 37 ensure the accuracy and stability of the movement of the horizontal slider 32 and the vertical slider 35. Two spaced stroke sensors 38 are also provided on the horizontal guide rail 31 and the vertical guide rail 34. A corresponding photosensitive block 39 is provided for the movement of the horizontal slider 32 and the vertical slider 35. The stroke sensor 38 is a photoelectric sensor. The movement range of the horizontal slider 32 and the vertical slider 35 is limited by the cooperation of the photosensitive block 39.

[0032] In this embodiment, the measuring component 40 includes a mounting block 41 disposed on a longitudinal slider 35 along the length of the mounting platform 20. The end of the mounting block 41 is connected to a vertically disposed vertical plate 411 by means of thread fixing, which serves as a reference plate for vertical adjustment. Both the upper and lower ends of the vertical plate 411 protrude from the mounting block 41. An angle iron 413 is provided between the upper end of the vertical plate 411 and the mounting block 41 for reinforcement and to increase the vertical effect.

[0033] In this embodiment, an adjusting block 42 protruding towards the product positioning frame 21 and suspended in mid-air is vertically slidably connected to the end of the mounting block 41 away from the longitudinal slider 35. The adjusting block 42 is fitted onto the vertical plate 411, increasing the reliability of vertical adjustment. Two vertically arranged strip holes 412 are provided on the vertical plate 411. Adjusting holes 421 communicating with the strip holes 412 are spaced apart on the adjusting plate. An adjusting hole 421 of suitable height is selected, and adjusting bolts 422 are connected for use. The adjusting bolts 422 abut against the edge of the strip hole 412, pass through the strip hole 412, and are threaded into the adjusting hole 421. Tightening the adjusting bolts 422 stabilizes the relative position of the adjusting block 42 and the vertical plate 411, or the two spaced adjusting bolts 422 are clamped and fixed to the mounting block 41. The detachable structure of the vertical plate 411 and the adjusting block 42 facilitates the adjustment and replacement of the measuring component 40. At the same time, the overall center of gravity is centered, which improves displacement stability and prevents the step probe 46 at the end from shaking during displacement.

[0034] In this embodiment, a horizontally protruding measuring platform 43 is detachably connected to the adjusting block 42. The detachable connection is achieved through a threaded fastening method. An angle iron 413 is provided between the upper end of the adjusting block 42 and the measuring platform 43 for reinforcement and to enhance the vertical effect. A hollow rotating platform 44 is provided on the measuring platform 43. The hollow rotating platform 44 is an existing transmission mechanism. A drive motor 45 is connected to the hollow rotating platform 44, and the drive motor 45 is connected to the shaft inside the hollow rotating platform 44 for transmission. A step difference probe 46 is connected to the output end of the hollow rotating platform 44. Specifically, a U-shaped protective frame 48 is provided at the bottom of the hollow rotating platform 44, and the step difference probe 46 is embedded in the U-shaped protective frame 48. The U-shaped protective frame 48 provides external protection for the step difference probe 46, and the bottom opening does not affect the measurement of the step difference probe 46. It is conceivable that the step difference probe 46 is first moved to the initial position point of the product positioning frame 21 by the horizontal drive component 30, and then the hollow rotating platform 44 is driven by the drive motor 45 to drive the step difference probe 46 to complete the step difference measurement of the arc trajectory, thereby improving the reliability of the measurement data and the universality of measurement for different products.

[0035] In this embodiment, a damper 47 is provided on the adjusting block 42 at the same height as the step probe 46. The damper 47 is adjusted up and down synchronously with the adjusting block 42 to limit the maximum rotation angle of the hollow rotating platform 44 and prevent the step probe 46 from colliding and shaking.

[0036] Ideally, the lower ends of the adjusting block 42 are provided with extensions 423 protruding from the edges of the vertical plate 411. The damper 47 is provided on the extensions 423. The structure of the extensions 423 is used to prevent the damper 47 from interfering when the vertical plate 411 and the adjusting block 42 are relatively displaced.

[0037] The measuring platform 43 is equipped with a rotation sensor 431, and the rotation transmission device is a U-shaped photoelectric sensor. The U-shaped protective frame 48 is equipped with a photosensitive film 481 that rotates through the rotation sensor 431. When the photosensitive film 481 passes through the U-shaped photoelectric sensor, it provides a signal for the measurement timing of the step difference probe 46 or the braking timing of the hollow rotating platform 44.

[0038] A barcode scanner 50 is provided on one side of the adjustment block 42. The barcode scanner 50 scans the QR code of the corresponding product before measurement and leaves information to facilitate product traceability on the production line.

[0039] It should be noted that the sensors, motors, barcode scanners 50, and other components mentioned in this embodiment are all commercially available parts, and their specific structures will not be described in detail.

[0040] Example 2: This utility model also provides a measurement system having the step difference circumferential measurement device as described above. Except for the step difference circumferential measurement device, the other components are all prior art or commercially available parts, and the specific structure is not described in detail.
