Description

Technical Field

[0001] This utility model relates to the field of industrial cameras, and in particular to an industrial camera clamping mechanism. Background Technology

[0002] An industrial camera clamping mechanism is a device used to fix an industrial camera. Its main function is to ensure the stability and accuracy of the camera during operation, thereby improving inspection efficiency and product quality.

[0003] Industrial cameras in the present technology are often fixed by traditional clamps, which adopt a fixed jaw design. The opening and closing range of the jaws is preset by the mechanical structure and cannot be automatically adjusted according to the workpiece size. In addition, the contact surface shape between the jaws and the workpiece is fixed, which can only be adapted to industrial cameras with a single shape and contour. Different sizes of industrial cameras cannot be quickly replaced, resulting in poor applicability. Utility Model Content

[0004] The present invention aims to solve the problem that in the prior art, industrial cameras are fixed by traditional clamps, which use a fixed gripper design. The opening and closing range of the gripper is preset by the mechanical structure and cannot be automatically adjusted according to the size of the workpiece, resulting in poor applicability.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: An industrial camera clamping mechanism includes a support body for supporting an industrial camera; an adjusting body disposed on the support body for adaptive clamping of industrial cameras of different sizes; the adjusting body includes at least three adjusting rods arranged radially and capable of synchronous radial extension and retraction; and a synchronous drive assembly tractively connected to the at least three adjusting rods, the synchronous drive assembly being used to receive a single power input and convert the power into an action that causes the at least three adjusting rods to synchronously generate radial displacement.

[0006] Furthermore, the synchronous drive assembly includes a circular plate rotatable about a central axis; a plurality of arc-shaped limiting frames fixed on the circular plate and corresponding in number to the adjusting rods, with one end of each adjusting rod housed in a corresponding arc-shaped limiting frame, the contour of the arc-shaped limiting frame being used to drive the adjusting rods to generate radial displacement when the circular plate rotates.

[0007] Furthermore, the synchronous drive assembly also includes a rotating rod fixedly connected to the circular plate shaft, and a drive source for driving the rotating rod to rotate.

[0008] Furthermore, the driving source is a servo motor or a stepper motor, which is mounted on the support and is connected to the rotating rod via a transmission.

[0009] Furthermore, the support body has adjustment holes corresponding to the adjustment rods, and the adjustment rods pass through the adjustment holes; at least one sliding groove is provided on the inner wall of each adjustment hole, and a slider that slides in cooperation with the sliding groove is fixed on the rod body of the adjustment rod in the adjustment hole.

[0010] Furthermore, the support body includes a support plate, and the adjustment hole is formed on the support plate; the support body also includes a base plate spaced apart from the support plate, and a partition plate for connecting the support plate and the base plate.

[0011] Furthermore, the circular plate is rotatably mounted on one side of the support plate via a bearing, and the drive source is mounted on the base plate.

[0012] Furthermore, a clamping housing is detachably mounted at the end of each of the adjusting rods away from the synchronous drive assembly.

[0013] Furthermore, the side of the clamping shell facing the clamping center is an arc-shaped concave surface, and the inner surface of the clamping shell is provided with anti-slip textures, such as roller textures or mesh textures, to increase friction.

[0014] Furthermore, the inner surface of the clamping shell is covered with an elastic buffer layer, the material of which is rubber, polyurethane, or silicone.

[0015] Compared with the prior art, the beneficial effects of this utility model include: This invention enables the device to be adapted to industrial cameras of different specifications by setting an adjustment body. A small servo motor drives the rotating rod to rotate, which causes the circular plate to move multiple arc-shaped limiting frames. The multiple limiting frames limit multiple adjusting rods. The slider and the slide groove enable multiple adjusting rods to move synchronously, thus adapting to different industrial cameras and greatly improving the applicability of the mechanism.

[0018] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0019] Example 1: Please see Figures 1 to 4 This embodiment discloses an industrial camera clamping mechanism, which is mainly used for fast, accurate and stable clamping of cylindrical or polygonal industrial cameras of different outer diameters on automated production lines or experimental platforms.

[0020] like Figure 1 As shown, this mechanism mainly includes a support body 1 that serves as the overall frame and an adjustment body 2 that realizes the core clamping function.

[0021] The support body 1 provides an installation reference and structural support for the various components of the adjusting body 2, and forms a protective shell. In this embodiment, the support body 1 consists of a support plate 11, a base plate 13, and at least one partition plate 12. The support plate 11 serves as the main functional mounting plate, and its material is preferably 7075 aluminum alloy that has undergone anodizing treatment to ensure strength, precision, and corrosion resistance. Multiple (four in this embodiment, evenly distributed at 90°) adjusting holes 21 for guiding and supporting the adjusting rod 24 are machined on the support plate 11 by CNC machining. The base plate 13 is arranged parallel to the support plate 11 and is used to install the power device. The partition plate 12 is vertically connected between the support plate 11 and the base plate 13, enhancing the structural rigidity of the entire support body 1 and providing dustproof and impact-proof protection for the internal transmission mechanism.

[0022] The adjusting body 2 includes a synchronous drive assembly. This assembly includes a small servo motor (as a drive source) mounted on the base plate 13, a rotating rod 25, a circular plate 22, and four arc-shaped limiting frames 23 fixed on the circular plate 22. The output shaft of the small servo motor (e.g., a compact servo motor from Inovance or Delta) is connected to the lower end of the rotating rod 25 via a coupling. The rotating rod 25 is vertically arranged along the central axis of the support body 1, and its upper end passes through a through hole in the center of the support plate 11 and is rotatably connected to the support plate 11 via a deep groove ball bearing to ensure smooth rotation and small radial runout.

[0023] The circular plate 22 is secured to the section of the rotating rod 25 located above the support plate 11 by a key or screw, and rotates synchronously with the rotating rod 25. On the upper surface of the circular plate 22, four arc-shaped limiting frames 23 are welded or screwed in a 90° evenly distributed manner. The inner contour of each limiting frame 23 is not a simple circular arc, but a designed cam curve (e.g., an Archimedean spiral or a constant acceleration / deceleration curve). This curve is designed so that when the circular plate 22 rotates by an angle, the radial distance from the contact point between the limiting frame 23 and the adjusting rod 24 to the central axis will undergo a predetermined linear or non-linear change.

[0024] All four adjusting rods 24 are straight rods, made of chrome-plated 45# steel or stainless steel to ensure wear resistance and straightness. Each adjusting rod 24 passes through an adjusting hole 21 on the support plate 11. A roller or slider is located at the rear end (near the center) of each adjusting rod 24, which is housed and always rests against the inner wall of a corresponding arc-shaped limiting frame 23. To ensure the linear motion accuracy of the adjusting rods 24 and prevent them from wobbling or rotating during movement, a guide mechanism is designed. Figure 2 , Figure 3 As shown, two parallel grooves 26 are machined on the upper and lower inner walls of each adjusting hole 21 by wire cutting or milling. Correspondingly, two sliders 27 are precision-machined and fixed on the upper and lower sides of each adjusting rod 24. The sliders 27 can be made of self-lubricating POM (polyoxymethylene) or PTFE (polytetrafluoroethylene), and their cross-sectional shape precisely matches the grooves 26 to form a sliding guide pair. This design ensures that the adjusting rod 24 can only perform high-precision radial linear reciprocating motion under the constraint of the grooves 26.

[0025] A clamping housing 28 is detachably attached to the front end (farthest from the center) of each adjusting rod 24 via threads. Figure 4As shown, the clamping shell 28 is the component that directly contacts the industrial camera. Its main body shape is not a hexagonal prism as shown in the attached figure. In this preferred embodiment, its inner side facing the clamping center is designed as a concave arc surface. The radius of curvature of this arc surface can be optimized according to the outer diameter range of common industrial cameras to achieve better enveloping contact. The inner surface of the clamping shell 28 is not directly made of metal; instead, a 1-2 mm thick elastic buffer layer (not shown in the figure) is bonded or integrally injection molded. The material is EPDM (ethylene propylene diene monomer) rubber, which has good elasticity and aging resistance. Furthermore, fine roller textures (i.e., anti-slip textures) are pressed onto the surface of this rubber buffer layer to greatly increase the static friction coefficient between it and the camera housing.

[0026] Work process and principles: S1: Place the industrial camera to be clamped roughly at the center of the clamping space formed by the four clamping shells 28.

[0027] S2: An external controller (such as a PLC or microcontroller) sends a clamping command (e.g., a target position or a forward rotation pulse) to the servo motor. The servo motor drives the rotating rod 25 and the circular plate 22 fixed thereon to rotate clockwise (or counterclockwise).

[0028] S3: As the circular plate 22 rotates, the four arc-shaped limiting frames 23 also rotate synchronously. The cam curves on their inner sides push the rear ends of the adjusting rods 24 they contact, forcing all the adjusting rods 24 to move radially towards the center synchronously and smoothly under the guidance of the slider 27 and the slide groove 26.

[0029] S4: The adjusting rod 24 drives the front clamping shell 28 to retract inward until the rubber buffer layer on the inner surface of the clamping shell 28 contacts the outer shell of the industrial camera. A torque limit can be set for the servo motor; when the clamping force reaches a preset value (i.e., the motor output torque reaches a threshold), the motor stops rotating, thus achieving reliable clamping of the camera. Because it is a synchronous mechanism, all four clamping shells 28 contact simultaneously and apply a uniform clamping force, automatically centering the camera.

[0030] S5: When the camera needs to be replaced, the controller sends a reverse rotation command to the servo motor. The circular plate 22 rotates in the reverse direction, and the contour guide adjustment rod 24 of the arc-shaped limit frame 23 moves outward radially in sync, thereby releasing the camera and completing the release action.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
