Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a jig for a grating scanner. Background Technique

[0002] With the rapid development of technology, grating scanners play an increasingly important role in many fields, such as industrial design, medical treatment, art, reverse engineering, and virtual reality. Through the grating principle and optical sensors, grating scanners have achieved high-precision and high-efficiency image scanning and digitization, greatly promoting the technological progress of these fields.

[0003] Most of the widely used grating scanner jigs in the current market are designed for objects with standard or regular shapes, such as cubes, cylinders, etc. Although these jigs can meet the clamping requirements within a certain range, they often seem powerless when faced with objects with complex shapes and variable sizes.

[0004] In view of the above and existing related technologies, the inventor believes that the following defects often exist: Traditional jigs usually have only a limited number of clamping points, and the positions of these clamping points are fixed and cannot be flexibly adjusted according to the shape of the scanning object; Most jigs are made of rigid materials and lack the necessary flexibility and adaptability, making it difficult to closely fit the surface of irregularly shaped objects, resulting in problems such as loose clamping, sliding, or scratching, and unable to adapt to the tight clamping of objects with different shapes and sizes.

[0005] Therefore, we propose a jig for a grating scanner. Summary of the Utility Model

[0006] In view of the problem that the above existing clamping points have fixed positions and cannot be flexibly adjusted according to the shape of the scanning object; Most jigs are made of rigid materials and lack the necessary flexibility and adaptability, making it difficult to closely fit the surface of irregularly shaped objects, resulting in problems such as loose clamping, sliding, or scratching, and unable to adapt to the tight clamping of objects with different shapes and sizes. The present utility model is proposed.

[0007] Therefore, the purpose of the present utility model is to provide a jig for a grating scanner, and its purpose lies in: a jig that is suitable for a grating scanner and can flexibly adapt to different shaped objects.

[0008] To solve the above technical problems, the present utility model provides the following technical solution: A jig for a grating scanner includes a rotating base, and a loading plate installed on the driving end of the rotating base. Both sides of the top of the loading plate are provided with translation components. The moving ends of the two translation components are both fixed with clamping frames. Installation cavities are opened on the opposite surfaces of the two clamping frames, and multiple rows of clamping components are fixedly installed inside the installation cavities;

[0009] The clamping assembly includes a fixed disk fixed inside the installation cavity and a clamping column that is limited and slides inside the installation cavity. A spring is fixed between the opposite surfaces of the clamping column and the fixed disk, and a rubber sheet is bonded to the end of the clamping column away from the fixed disk.

[0010] As a preferred solution of the fixture for a grating scanner described in the present invention, wherein: limiting grooves are provided at both ends of the outer wall of the clamping column and the fixed disk, and limiting guide bars are slidably installed between the movable ends of the limiting grooves on the clamping column and the fixed disk, and the limiting guide bars are fixed inside the installation cavity.

[0011] As a preferred solution of the fixture for a grating scanner described in the present invention, wherein: a first spring fixing column is welded to the end of the clamping column close to the fixed disk, and a second spring fixing column is welded to the end of the fixed disk close to the clamping column, and the fixed disk is fixed between the first spring fixing column and the second spring fixing column.

[0012] As a preferred solution of the fixture for a grating scanner described in the present invention, wherein: a first magnet is fixed to the end of the first spring fixing column away from the clamping column, a second magnet is fixed to the end of the second spring fixing column away from the fixed disk, and the opposite surfaces of the first magnet and the second magnet are in a magnetically repulsive state.

[0013] As a preferred solution of the fixture for a grating scanner described in the present invention, wherein: equipment cavities are provided on both sides of the top of the material loading plate, and the translation assembly includes a linear motor fixed inside the equipment cavity, and the movable end of the linear motor is fixedly connected to the bottom of the clamping frame.

[0014] As a preferred solution of the fixture for a grating scanner described in the present invention, wherein: the translation assembly further includes two guide rails fixed to the top of the material loading plate, and sliders that slide on the guide rails are installed at both ends of the bottom of the clamping frame.

[0017] The beneficial effects of the present invention:

[0018] 1. In the present utility model, under the elastic action of the spring, the clamping column is pushed back towards the object, thereby clamping the object between the two side clamping columns. At the same time, the distance between magnet one and magnet two is relatively shortened, and the shortening of the distance will cause the repulsive force between magnet one and magnet two to become stronger. Since magnet two is in a fixed state, a thrust towards the object is applied to the clamping column, which is beneficial to improving the tightness of the contact between the clamping column and the object, and further improving the clamping effect on the object. Moreover, due to the setting of the rubber sheet, when the clamping column clamps the object, the rubber sheet will be deformed by force and fit more closely to the surface of the object, making the clamping more secure.

[0019] 2. In the present utility model, two groups of clamping components distributed in a rectangular shape are arranged on both sides of the object, and the size of each clamping component is small and is installed separately. When clamping the object, the clamping component only plays a role in clamping the object when it comes into contact with the surface of the object. There are many clamping points and they are fixed, and it can be self-adapted according to the surface formation of the object to be clamped, and can fit the surface of an irregularly shaped object, and is suitable for firmly clamping objects of different shapes and sizes.

[0020] 3. After clamping the object in the present utility model, the driving motor drives the loading plate to rotate, which can drive the object clamped on the top of the loading plate to rotate, thereby realizing the 360-degree rotation of the object. This is more conducive to the scanner to perform a full-range and non-blind-angle scan of the object. At the same time, the gravity of the object will be evenly distributed to the bottom plate through the universal ball and the support leg, preventing the force from concentrating on the driving end of the driving motor, playing a protective role for the driving motor, extending the service life of the fixture, and also improving the smoothness of use. Moreover, the support leg rolls on the top of the bottom plate, with a small friction coefficient, and the loading plate rotates more smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific implementation manners of the present utility model will be described in detail below with reference to the accompanying drawings of the specification.

[0029] Embodiment 1

[0030] Referring to Figures 1-4 , which is the first embodiment of the present utility model, a fixture for a grating scanner is provided. Such a fixture for a grating scanner includes a rotary base 1 and a loading plate 2 mounted on the driving end of the rotary base 1. Translation components 3 are mounted on both sides of the top of the loading plate 2. Clamping frames 4 are fixed to the movable ends of the two translation components 3. Installation cavities 41 are formed on the opposite surfaces of the two clamping frames 4, and multiple rows of clamping components 5 are fixedly installed inside the installation cavities 41;

[0031] The clamping component 5 includes a fixed disk 58 fixed inside the installation cavity 41 and a clamping column 51 slidably limited inside the installation cavity 41. A spring 56 is fixed between the opposite surfaces of the clamping column 51 and the fixed disk 58. Under the elastic action of the spring 56, the clamping column 51 is pushed back towards the object, thereby clamping the object between the two clamping columns 51 on both sides. A rubber sheet 52 is bonded to the end of the clamping column 51 away from the fixed disk 58. The rubber sheet 52 is provided to deform under force when the clamping column 51 clamps the object, making it more conform to the surface of the object and clamping more firmly.

[0032] Two groups of clamping components 5 distributed in a rectangular shape are provided on both sides of the object. Each clamping component 5 has a small size and is installed separately. When clamping the object, the clamping component 5 only plays a role in clamping the object when it contacts the surface of the object. There are many and fixed clamping points, which can be self-adapted according to the surface formation of the object to be clamped, and can conform to the surface of an irregularly shaped object, so as to firmly clamp objects of different shapes and sizes.

[0033] Limit grooves 53 are provided at both ends of the outer wall of the clamping column 51 and the fixed disk 58. A limit guide bar is slidably installed between the movable ends of the limit grooves 53 on the clamping column 51 and the fixed disk 58, and the limit guide bar is fixed inside the installation cavity 41. The length of the limit guide bar is greater than five centimeters of the width of the installation cavity 41. In the initial state, the limit guide bar completely passes through the limit groove 53 on the fixed disk 58, and the other end enters the limit groove 53 on the clamping column 51 by five centimeters. The limit guide bar is used to support and limit the clamping column 51, enabling it to linearly translate and slide.

[0034] A first spring fixing column 54 is welded to one end of the clamping column 51 close to the fixed disk 58, and a second spring fixing column 59 is welded to one end of the fixed disk 58 close to the clamping column 51. The fixed disk 58 is fixed between the first spring fixing column 54 and the second spring fixing column 59.

[0035] A first magnet 55 is fixed to the end of the first spring fixing column 54 away from the clamping column 51, and a second magnet 57 is fixed to the end of the second spring fixing column 59 away from the fixed disk 58. The opposite faces of the first magnet 55 and the second magnet 57 are in a magnetically repulsive state. When the distance between the clamping column 51 and the fixed disk 58 is shortened, the distance between the first magnet 55 and the second magnet 57 is relatively shortened. The shortening of the distance will cause the repulsive force between the first magnet 55 and the second magnet 57 to become stronger. Since the second magnet 57 is in a fixed state, a thrust towards the object is applied to the clamping column 51, which helps to improve the tightness of the contact between the clamping column 51 and the object, thereby improving the clamping effect on the object.

[0036] Device cavities 21 are provided on both sides of the top of the material loading plate 2. The translation assembly 3 includes a linear motor 31 fixed inside the device cavity 21, and the movable end of the linear motor 31 is fixedly connected to the bottom of the clamping frame 4.

[0037] The translation assembly 3 further includes two guide rails 32 fixed to the top of the material loading plate 2. Sliders 33 that slide on the guide rails 32 are installed at both ends of the bottom of the clamping frame 4.

[0038] During use, the bottom of the object to be scanned is placed between the opposite faces of the two clamping frames 4. The two linear motors 31 on both sides are simultaneously driven to drive the clamping frame 4 to move towards the middle, clamping the object between the two clamping assemblies 5 on both sides. The fixing process of the object by the two clamping assemblies 5 is as follows:

[0039] When the clamping column 51 contacts the object, the object applies a thrust towards the fixed disk 58 to the clamping column 51, causing the clamping column 51 to compress the spring 56 to shorten the distance between the clamping column 51 and the fixed disk 58. Under the elastic action of the spring 56, the clamping column 51 is pushed back towards the object, thereby clamping the object between the two clamping columns 51 on both sides.

[0040] Embodiment 2

[0041] Refer to Figures 1-4 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that:

[0042] The rotating base 1 includes a bottom plate 11. At the center of the end face of the bottom plate 11 close to the loading plate 2, a driving motor 12 is fixed, and the driving end of the driving motor 12 is fixedly connected to the bottom of the loading plate 2. The driving motor 12 drives the loading plate 2 to rotate, so as to drive the object clamped on the top of the loading plate 2 to rotate, thereby realizing the 360-degree rotation of the object, which is more conducive to the scanner to perform a full-range and non-blind-angle scan of the object.

[0043] A circle of universal balls 14 is fixed at the bottom of the loading plate 2 with the driving motor 12 as the center. One end of the universal ball 14 close to the bottom plate 11 is provided with a leg 13 that rolls on the bottom plate 11. The object is clamped on the top of the loading plate 2, and the gravity of the object will be evenly distributed on the bottom plate 11 through the universal ball 14 and the leg 13, preventing the force from concentrating on the driving end of the driving motor 12, playing a protective role for the driving motor 12, extending the service life of the fixture, and also improving the smoothness of use. Moreover, the leg 13 rolls on the top of the bottom plate 11, with a low coefficient of friction, and the loading plate 2 rotates more smoothly.

[0044] During the use process, after clamping the object, the driving motor 12 drives the loading plate 2 to rotate, so as to drive the object clamped on the top of the loading plate 2 to rotate, thereby realizing the 360-degree rotation of the object.

[0045] The remaining structures are the same as those in Embodiment 1.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not restrictive. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
