Description

Technical Field

[0001] This utility model relates to the field of laboratory gripper technology, specifically to a laboratory gripper suitable for testing the magnetic anomaly of materials. Background Technology

[0002] In the process of conducting magnetic anomaly testing on materials in the laboratory, it is often necessary to use grippers to grasp and move containers such as test tubes containing materials in order to achieve material transfer, positioning and other testing steps.

[0003] Existing grippers typically have flat or simple curved gripping surfaces, resulting in a small contact area with cylindrical materials such as test tubes. During gripping and movement, friction is provided only through this small contact area, making it easy for materials to slip, shift, or even fall. This not only affects the continuity and accuracy of testing but also poses potential safety hazards due to material falling.

[0004] Meanwhile, existing laboratory grippers mostly employ rigid clamping structures, lacking effective cushioning components. When gripping materials such as test tubes, the grippers are in hard contact with the material, making it difficult to precisely control the clamping force. This can easily cause crushing damage to the test tubes due to excessive clamping, especially for thin-walled test tubes or containers containing fragile materials. Such hard compression may directly lead to test tube breakage, affecting the testing process and causing material loss.

[0005] To address the aforementioned problems, this invention provides a laboratory gripper suitable for testing the magnetic anomaly of materials. Utility Model Content

[0006] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a laboratory gripper suitable for testing the magnetic anomaly of materials. By incorporating an elastic pad, the elasticity of the pad itself can buffer the clamping force during the gripping process, preventing hard compression damage to materials such as test tubes. Furthermore, after deformation, the elastic pad can better conform to the outer wall of the test tube, increasing the contact area with the test tube, enhancing the gripping friction, and preventing slippage, displacement, or even falling.

[0007] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: This utility model provides a laboratory gripper suitable for testing the magnetic anomaly of materials, comprising: A substrate, which is connected to an external driving device through mounting holes provided thereon; The drive unit is mounted on the base plate and is driven by an external air pump; Two grippers are located on both sides of the drive unit and are controlled by the drive unit to slide towards or away from each other simultaneously. A buffer assembly is provided on one side of the two grippers facing each other.

[0008] Preferably, the driving unit includes: A parallel gripper cylinder is mounted on a base plate by bolts, and connecting plates are mounted on the output rods at both ends of the parallel gripper cylinder. The connecting plates are connected to the grippers by bolts.

[0009] Preferably, a V-shaped groove is provided on one side of the two grippers facing each other, and the buffer assembly is installed on the groove wall of the V-shaped groove.

[0010] Preferably, the buffer component includes: Four elastic pads are installed on the walls of the corresponding V-shaped grooves, and when the test tube is clamped, the four elastic pads simultaneously press against the side wall of the test tube.

[0011] Preferably, the elastic pad is an arc shape that bulges towards the middle of the two grippers.

[0012] Preferably, the two sides of the V-shaped groove are provided with mounting grooves, and the two ends of the elastic pad are fixedly connected to the two sides of the mounting groove opening.

[0013] Preferably, multiple support parts are installed between the elastic pad and the bottom sidewall of the corresponding mounting groove to improve the support force of the elastic pad.

[0014] Preferably, the support portion includes: A support rod is fixedly connected to the side of the elastic pad near the bottom wall of the mounting groove. A limiting groove is provided on the bottom side wall of the mounting groove, and the support rod is inserted into the corresponding limiting groove.

[0015] Preferably, an elastic element is installed between one end of the support rod located inside the limiting groove and the bottom sidewall of the limiting groove. This elastic element has a clamping force that presses the support rod against the elastic pad.

[0016] Preferably, the elastic element includes a plurality of arched spring pieces, which are distributed circumferentially along the support rod, with the arched tops of the spring pieces facing the axial direction of the support rod. One end of the arched foot is fixedly connected to the support rod, and the other end of the arched foot abuts against the bottom sidewall of the limiting groove.

[0017] The beneficial effects of this utility model are as follows: This invention utilizes the V-shaped groove and elastic pads to buffer the clamping force during the clamping process, preventing hard compression damage to the test tube. Simultaneously, the four arc-shaped elastic pads press firmly against the sidewall of the test tube during clamping, increasing the contact area. Furthermore, the arc-shaped structure of the elastic pads, after deformation, better conforms to the outer wall of the test tube, enhancing the clamping friction and effectively preventing the test tube from slipping or falling during gripping and movement.

[0018] This invention, through the design of a support rod and a spring sheet, enables the support rod to enhance the axial support force of the elastic pad on the test tube during clamping, while the spring sheet increases the support force of the elastic pad on the test tube wall, thereby further improving clamping stability.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This invention provides a laboratory gripper suitable for testing the magnetic anomaly of materials, such as... Figures 1 to 6 As shown. Example 1: A laboratory gripper suitable for testing the magnetic anomaly of materials includes a base plate 1 with multiple mounting holes. Bolts passing through these holes allow for rigid connection to an external drive device (such as a robotic arm), ensuring overall positional stability during material transfer. A drive unit, employing a parallel gripper cylinder 3, is mounted on the base plate 1. The cylinder body is secured to the base plate 1 with multiple bolts. Connecting plates 4 are mounted on the output rod ends of the parallel gripper cylinder 3. One end of each connecting plate 4 is bolted to the output rod of the parallel gripper cylinder 3, and the other end is bolted to a gripper 2.

[0029] When an external air pump inputs compressed air into the parallel gripper cylinder 3 through an air pipe, the piston inside the cylinder drives the output rod to perform linear reciprocating motion, which in turn drives the two grippers 2 to slide synchronously in opposite directions or in opposite directions through the connecting plate 4. When they slide in opposite directions, they clamp the test tube; when they slide in opposite directions, they release the test tube.

[0030] The two grippers 2 have a V-shaped groove 6 on one side facing each other, which can fit the outer circumference of most cylindrical test tubes, increasing the contact area with the test tube and thus improving the stability of the gripping.

[0031] Example 2: Based on Embodiment 1, to avoid hard compression damage to the test tube during clamping, a buffer assembly is provided on the wall of the V-shaped groove 6. During clamping, the buffer assembly acts as a buffer to protect the test tube. The buffer assembly includes four elastic pads 5, which are respectively installed on the two side walls of the two V-shaped grooves 6. The main body of the elastic pad 5 is an arc shape protruding towards the center of the gripper 2. Mounting grooves 7 are formed on the two side walls of the V-shaped groove 6 at corresponding positions of the elastic pads 5. The two ends of the elastic pads 5 are fixed to the groove walls at the openings of the mounting grooves 7. With a fixed connection, the arc-shaped design of the elastic pad 5 allows the middle part of the elastic pad 5 to be suspended above the mounting groove 7. When the clamp 2 holds the test tube, the outer wall of the test tube first contacts the arc surface of the elastic pad 5. As the clamp 2 continues to approach, the elastic pad 5 is squeezed and deformed into the mounting groove 7, thereby gradually increasing the contact area between the elastic pad 5 and the outer wall of the test tube. The four elastic pads 5 apply force simultaneously from four points on the outer periphery of the test tube, which not only avoids the test tube breakage caused by rigid contact, but also prevents the test tube from slipping through the high friction of the silicone material, achieving the dual effect of buffering and clamping stability.

[0032] Example 3: Based on Embodiment 2, in order to enhance the support capacity of the buffer assembly and improve the stability of clamping, this embodiment adds multiple support parts between the elastic pad 5 and the bottom sidewall of the mounting groove 7. Each support part includes a support rod 8, one end of which is fixedly connected to the side of the elastic pad 5 near the bottom sidewall of the mounting groove 7, and the other end is inserted into a limiting groove 9 provided on the bottom sidewall of the mounting groove 7. The support rod 8 can slide axially along the limiting groove 9. An elastic element is installed at the end of the support rod 8 located within the limiting groove 9. This elastic element has a force that presses the support rod 8 against the elastic pad 5. Multiple arched spring pieces 10 are evenly distributed circumferentially. One arched foot of each spring piece 10 is fixedly connected to the end of the support rod 8, and the other arched foot naturally presses against the bottom sidewall of the limiting groove 9, with the arch apex facing the axial direction of the support rod 8.

[0033] When the elastic pad 5 deforms into the mounting groove 7 under the pressure of the test tube, it drives the support rod 8 to move into the limiting groove 9. At this time, the spring piece 10 undergoes elastic deformation under the pressure of the support rod 8 and the bottom of the limiting groove 9, and the dome contracts in the axial direction, generating an outward elastic force to push the support rod 8, giving the elastic pad 5 additional support. At the same time, the limiting groove 9 restricts the radial displacement of the support rod 8, ensuring that the elastic force of the spring piece 10 is transmitted axially to the elastic pad 5. This, combined with the elastic deformation of the elastic pad 5 itself, not only ensures the buffer protection of the test tube but also improves the anti-deformation ability during clamping, further enhancing the stability of the test tube clamping.

[0034] Since this utility model is a gripper used for detecting magnetic anomalies, in order to prevent more magnetic anomalies from being generated, the connecting plate 4, gripper 2, elastic pad 5, support rod 8 and spring piece 10 are all made of engineering plastics.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
