Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a friction-based quick-locking clamp. Background Technology

[0002] Existing friction testing machines often use clamps for clamping when testing small-sized tubes or guide wires. Traditional clamps typically have the following drawbacks: 1. After the product is clamped, it is difficult to keep the product's center axis in the exact center of the fixture, resulting in the product's center of gravity being inconsistent with the fixture's center of gravity; 2. For longer or heavier products, tilting is likely to occur during clamping, resulting in unstable clamping; 3. The center of gravity of the fixture itself is not at the geometric center, which creates a lever arm on the axis of the tension sensor, causing the tension value of the sensor to deviate from the actual tension. 4. The clamping and unclamping operations are time-consuming, affecting testing efficiency.

[0003] Therefore, a new type of clamp is needed that can quickly clamp the product and ensure that the product's center of gravity is coaxial with the sensor, avoiding tilting. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-locking clamp for a friction machine, which solves the problems of inaccurate centering, unstable center of gravity, and inconvenient operation of traditional clamps.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A friction-based quick-locking clamp, comprising: Connecting rod, the connecting rod being used to connect the tension sensor; A base fixed to the connecting rod; A screw, which is rotatably mounted in the base via a screw mounting bracket, and the two ends of the screw are respectively provided with left-hand threads and right-hand threads; The left and right sliders are respectively screwed onto the left-hand and right-hand threads of the screw, and are distributed opposite each other along the axial direction; The left and right locking nuts are installed at both ends of the screw and are used to quickly control the opening and closing of the clamp.

[0006] Preferably, silicone sheets are provided on the inner sides of the left and right sliders respectively.

[0007] Preferably, the connecting rod is coaxially arranged with the tension sensor, and the center of gravity of the product, the center of gravity of the fixture, and the center of gravity of the sensor are located in the same plane.

[0008] Preferably, the silicone sheet is divided into two groups of four sheets to form a clamping surface for holding the product.

[0009] Preferably, the silicone sheet is arranged in two groups, one above the other, to prevent long or top-heavy products from tilting during clamping.

[0010] Preferably, the silicone sheet is made of wear-resistant and pressure-resistant silicone material to increase friction and prevent damage to the product surface.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. Enabled rapid clamping and release of products; 2. This ensures that the center position of the product coincides with the center axis of the fixture, eliminating measurement errors caused by eccentricity; 3. The use of multiple silicone sheets improves the stable support for long products, resulting in a more secure clamping effect; 4. Compact structure, easy operation, suitable for tube or guide wire products. Attached Figure Description

[0016] 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.

[0017] Please see Figures 1 to 4 A friction-based machine quick-locking clamp includes a connecting rod 1, a base 2, a screw 3, a left slider 4, a right slider 5, a left locking nut 6, a right locking nut 7, and a silicone sheet 8.

[0018] The connecting rod 1 is fixedly connected to the tension sensor via threads, and the base 2 is sleeved on and fixed to the connecting rod 1. The screw 3 is rotatably installed in the base 2 via a screw mounting bracket. The left end of the screw 3 has left-hand threads, and the right end has right-hand threads. The left slider 4 and the right slider 5 are screwed to the left-hand threads and right-hand threads of the screw 3, respectively.

[0019] At both ends of the screw 3, a left locking nut 6 and a right locking nut 7 are respectively installed. Rotating either locking nut will quickly push the sliders 4 and 5 to move synchronously, thereby clamping or releasing the product.

[0020] On the inner surfaces of the left slider 4 and the right slider 5, which are opposite each other, there are silicone sheets 8. The silicone sheets are divided into two groups of four sheets, symmetrically distributed vertically, for clamping tubes or guide wires. Due to the bidirectional threaded structure, the left and right sliders retract symmetrically at the same time, ensuring that the product is always located at the exact center of the clamp axis.

[0021] When using, place the product between the two sets of silicone sheets and rotate the left locking nut 6 or the right locking nut 7 to quickly clamp it; after the test is completed, rotate the nut in the opposite direction to quickly release the product.

[0022] This clamp is suitable for small-diameter tubes or guide wires of different lengths and weight distributions, ensuring clamping stability and measurement accuracy.

[0023] The specific structural dimensions and materials can be appropriately adjusted according to different application environments without affecting the core technical solution of this utility model.

[0024] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
