[0035] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0036] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0038] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0039] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0040] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0041] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0042] Figure 1 This is a structural schematic diagram of the centering positioning clamping device in use according to one embodiment of the present disclosure. Figure 2 This is a schematic diagram of the centering positioning clamping device according to one embodiment of the present disclosure. Figure 3 This is a structural schematic diagram of a partial structure of a centering positioning clamping device according to one embodiment of the present disclosure.Figure 4 yes Figure 3 Side view.

[0043] like Figures 1 to 4 As shown, the centering positioning and clamping device of this disclosure can center and clamp an object during use. Specifically, the centering positioning and clamping device of this disclosure may include components such as a base plate 100, an upper base plate 200, a positioning block 300, and a driving device 400.

[0044] The base plate 100 of this disclosure is generally square in shape. However, those skilled in the art will recognize that the base plate 100 may vary depending on the shape of the object to be positioned and clamped.

[0045] The upper seat plate 200 and the base plate 100 are spaced apart by a predetermined distance. In one embodiment, the upper seat plate 200 and the base plate 100 have similar shapes, but the area of ​​the upper seat plate 200 is smaller than that of the base plate 100. Specifically, the upper seat plate 200 of this disclosure has a smaller length direction dimension than the base plate 100 in the length direction, and a smaller width direction dimension than the base plate 100 in the width direction.

[0046] In one specific embodiment, the upper seat plate 200 is connected to the base plate 100 by support columns. For example, there can be four support columns, which are respectively located at the four corners of the upper seat plate 200. In this case, the lower end of the support column is fixed to the base plate 100, and the upper end of the support column is fixed to the upper seat plate 200.

[0047] like Figure 2 As shown, the upper seat plate 200 of this disclosure has a notch at the position relative to the positioning block 300. When the positioning block 300 moves in a direction close to the upper seat plate 200, at least a portion of the positioning block 300 can move into the notch. Thus, the positioning block 300 can center and clamp objects smaller than the upper seat plate 200.

[0048] like Figure 3 As shown, at least three tracks 500 are provided on the base plate 100, and these three tracks 500 are located on different radii of the same circle. That is to say, the extensions of these at least three tracks 500 intersect at a point, which is the center of the circle.

[0049] In one specific embodiment, there are four tracks 500, two of which are located on a first straight line and the other two are located on a second straight line, and the first and second straight lines are perpendicular to each other.

[0050] Positioning blocks 300 are slidably disposed on the base plate 100. Specifically, positioning blocks 300 are slidably disposed on the track 500, thereby allowing the positioning blocks 300 to change position relative to the base plate 100. This allows the positioning blocks 300 to approach or move away from the upper seat plate 200, i.e., to approach or move away from objects placed on the upper seat plate 200. Furthermore, at least a portion of the positioning blocks 300 is located above the upper seat plate 200; thus, when the positioning blocks 300 approach the object, they can achieve centered positioning and clamping of the object; when the positioning blocks 300 move away from the object, they can release the object.

[0051] In this disclosure, the number of positioning blocks 300 is the same as the number of tracks 500. Specifically, the positioning blocks 300 in this disclosure can also be set to four.

[0052] In some embodiments, the positioning block 300 includes a rubber-coated positioning plate 310, at least a portion of the upper end of which is located above the upper seat plate 200. Thus, the rubber-coated positioning plate 310 can contact the object and position and clamp the object; and the positioning block 300 will not cause damage to the object during the positioning and clamping process.

[0053] like Figure 3 and Figure 4 As shown, the drive device 400 is used to drive the positioning block 300 to move; the drive device 400 can drive the positioning block 300 to move synchronously so that the positioning block 300 can be centered and clamp the object on the upper plate 200.

[0054] In one specific embodiment, the drive device 400 is a rotary cylinder. The rotary cylinder can be fixed to the base plate 100, and the output shaft of the rotary cylinder passes through the base plate 100 and is located above the base plate 100.

[0055] The drive device 400 disclosed herein is used to drive the drive plate 600 to rotate; specifically, the drive plate 600 can be fixed to the output shaft of the drive device 400, at which time the drive plate 600 can be set approximately horizontally and rotate along the vertical axis. Moreover, when the drive plate 600 rotates, the drive positioning block 300 slides along the track 500.

[0056] In a preferred embodiment, the rotation axis of the drive plate 600 passes through the center of the aforementioned circle, so that the centering positioning clamping device of this disclosure will not produce eccentric movement, and the movement process of the centering positioning clamping device is more stable.

[0057] The positioning block 300 also includes a guide member 320, which can be a cam follower; the drive plate 600 is provided with a guide groove 610, and when the drive plate 600 rotates, the guide member 320 can slide in the guide groove 610, so that the positioning block 300 is located at different positions on the track 500.

[0058] The guide groove 610 of this disclosure is configured such that when the drive plate 600 rotates in a first direction, the positioning blocks 300 move closer to each other; and when the drive plate 600 rotates in a second direction, the positioning blocks 300 move further apart. Figure 3 The directions shown can be either counterclockwise or clockwise.

[0059] In other words, by setting guide grooves 610 of different shapes, the positioning block 300 can move at different speeds, thereby enabling the centering positioning clamping device to meet the positioning needs of different objects.

[0060] In one specific embodiment, four guide grooves 610 are provided, and correspondingly, each guide groove 610 corresponds to one positioning block 300. Moreover, the four guide grooves 610 of this disclosure have the same structure, so that when the drive plate 600 rotates, the four positioning blocks 300 of this disclosure have the same direction of movement and speed of movement.

[0061] See again Figure 3 In this disclosure, the guide groove 610 is arc-shaped, and along the first direction, one end of the guide groove 610 is closer to the rotation axis of the drive plate 600 than the other end of the guide groove 610.

[0062] The centering positioning clamping device disclosed herein solves the problem that some products cannot be positioned near the edge due to friction and the positioning reference being in the center. It uses a mechanical structure instead of a traditional gripper cylinder, resulting in a more stable structure and smaller installation space. Driven by a single power source, the control logic is simple, operation is convenient, the structure is compact, stability is good, and the cost-effectiveness is high. Furthermore, the overall structure of the centering positioning clamping device disclosed herein has fewer parts, making maintenance easy.

[0063] In addition, the centering positioning clamping device disclosed herein utilizes the lever principle and cam structure, making the structural layout more scientific and reasonable; the structure can adjust the tilt angle and clamping size, and is compatible with a variety of products; all components in contact with the product are coated with rubber / foam to prevent product damage; and all standard parts used are common, low-cost standard parts; therefore, the centering positioning clamping device disclosed herein has low manufacturing cost and is easy to promote.
