[0002] Currently, clamping mechanisms are increasingly used in product production. Conventional clamping mechanisms offer limited grip on cylindrical products, especially heavy ones, which can easily come loose. Therefore, a clamping mechanism has been designed to address this issue.
[0003] It should be noted that the above technical background is merely for the purpose of providing a clear and complete description of the technical solutions of the present invention and to facilitate understanding by those skilled in the art. It should not be assumed that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present invention. Utility Model Content
[0004] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a clamping mechanism.
[0005] In order to achieve the above purpose and other related purposes, the technical solution provided by the present invention is: a clamping mechanism, including an inner mounting seat, on which a first rocker arm and a second rocker arm are rotatably arranged, the lower end of the first rocker arm is provided with a first clamping jaw, and the lower end of the second rocker arm is provided with a second clamping jaw, and the first clamping jaw and the second clamping jaw are arranged symmetrically; it also includes an outer mounting seat, which is movably sleeved on the inner mounting seat, and the outer mounting seat is provided with a first bearing and a second bearing that are symmetrically arranged on the outer mounting seat; the first bearing is located on the outside of the first rocker arm, and the second bearing is located on the outside of the second rocker arm.
[0006] A first hook is provided at the upper end of the first swing arm, and a second hook is provided at the upper end of the second swing arm. In the open state, the first hook hooks the first bearing, and the second hook hooks the second bearing. In the clamping state, the first bearing presses the first swing arm, and the second bearing presses the second swing arm. In this embodiment, when the outer mounting seat is located above the inner mounting seat, the first and second swing arms are in an open position in an "eight" shape. When the outer mounting seat moves downward, the first and second bearings roll downward, and the first bearing compresses the first swing arm to move the first clamping jaw inward, while the second bearing compresses the second swing arm to move the second clamping jaw inward, until the first and second clamping jaws clamp the product, preventing it from falling out.
[0007] Furthermore, the distance between the contact surface between the first swing link and the first bearing, and the contact surface between the second swing link and the second bearing, gradually widens from top to bottom. In this embodiment, both contact surfaces are inclined. When the outer mounting seat moves downward, the first bearing compresses the first swing link, causing the first clamping jaw to move inward, and the second bearing compresses the second swing link, causing the second clamping jaw to move inward. The first and second clamping jaws press together to clamp the product. The inclined surface design increases the clamping force of the first and second clamping jaws, ensuring a secure clamping position.
[0008] Furthermore, the first bearing is arranged inside the outer mounting seat via a first connecting shaft, and the second bearing is arranged inside the outer mounting seat via a second connecting shaft. In this solution, the mounting is stable and the bearings are easy to rotate.
[0009] Furthermore, the first swing arm is rotatably mounted on the inner mounting seat via a first rotating shaft, and the second swing arm is rotatably mounted on the inner mounting seat via a second rotating shaft. In this solution, the rotational connection between the swing arm and the inner mounting seat is ensured, and the rotation is more flexible.
[0010] Furthermore, the first clamping jaw and the first swing arm are detachably arranged, and the second clamping jaw and the second swing arm are detachably arranged. In this solution, the clamping jaws are easily replaced, and the scope of use of the clamping mechanism is expanded.
[0011] Furthermore, a push rod that can move up and down is provided inside the inner mounting seat. In this solution, the setting of the push rod is convenient for pressing the product, keeping the product stable, and facilitating the first clamping jaw and the second clamping jaw to clamp the product.
[0012] Furthermore, the push rod is connected to the telescopic end of a first linear cylinder and is moved up and down by the first linear cylinder; the outer mounting base is connected to the telescopic end of a second linear cylinder and is moved up and down by the second linear cylinder. In this solution, the vertical movement is achieved by the linear cylinders, which is fast and efficient.
[0013] Furthermore, the second linear cylinders are provided with two and are respectively located on both sides of the inner mounting seat. In this solution, two linear cylinders are provided to drive the up and down movement of the outer mounting seat, and the movement is more efficient and stable.
[0014] Furthermore, the mounting end of the first linear cylinder, the mounting end of the second linear cylinder and the inner fixing seat are all fixed on a fixing seat. In this solution, the stability of the overall structure is guaranteed.
[0015] Due to the application of the above technical solution, the present invention has the following beneficial effects compared with the prior art:
[0016] The clamping mechanism designed in this utility model can move downward through the outer mounting seat to achieve the clamping of the product by the first clamping jaw and the second clamping jaw. The clamping force gradually increases until the product is clamped. Even if the product is heavy, there is no risk of loosening. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Example:
[0028] See attached Figure 1 and attached Figure 3 As shown, this embodiment provides a clamping mechanism, comprising an inner mounting base 1, on which a first swing link 2 and a second swing link 3 are rotatably mounted, with a first clamping jaw 4 disposed at the lower end of the first swing link 2 and a second clamping jaw 5 disposed at the lower end of the second swing link 3, the first clamping jaw 4 and the second clamping jaw 5 being symmetrically arranged. The mechanism also comprises an outer mounting base 6, which is mounted on the inner mounting base 1 in an up-and-down manner and is provided with a first bearing 7 and a second bearing 8 disposed symmetrically thereon. The first bearing 7 is located outside the first swing link 2, and the second bearing 8 is located outside the second swing link 3. A first hook 9 is disposed at the upper end of the first swing link 2, and a second hook 10 is disposed at the upper end of the second swing link 3. In the open state, the first hook 9 hooks onto the first bearing 7, and the second hook 10 hooks onto the second bearing 8. In the clamping state, the first bearing 7 presses against the first swing link 2, and the second bearing 8 presses against the second swing link 3.
[0029] Principle: When the outer mounting seat 6 is located at a higher position than the inner mounting seat 1, the first rocker arm 2 and the second rocker arm 3 are in an eight-shaped open state. When the outer mounting seat 6 moves downward, the first bearing 7 and the second bearing 8 roll downward. The first bearing 7 squeezes the first rocker arm 2 to move the first clamping jaw 4 inward, and the second bearing 8 squeezes the second rocker arm 3 to move the second clamping jaw 5 inward until the first clamping jaw 4 and the second clamping jaw 5 clamp the product.
[0030] See attached Figure 2 and attached Figure 4 As shown, the distance between the contact surface between the first swing link 2 and the first bearing 7, and the contact surface between the second swing link 3 and the second bearing 8, gradually widens from top to bottom. In this embodiment, both contact surfaces are inclined. When the outer mounting base 6 moves downward, the first bearing 7 compresses the first swing link 2, causing the first clamping jaw 4 to move inward, and the second bearing 8 compresses the second swing link 3, causing the second clamping jaw 5 to move inward. The first and second clamping jaws 4 and 5 are pressed together to clamp the product. The inclined surface design increases the clamping force of the first and second clamping jaws 4 and 5, ensuring a tight clamping force.
[0031] See attached Figure 2 and attached Figure 4 As shown, the first bearing 7 is arranged inside the outer mounting seat 6 through the first connecting shaft 11, and the second bearing 8 is arranged inside the outer mounting seat 6 through the second connecting shaft 12. In this embodiment, the installation is stable and the bearings are easy to rotate.
[0032] See attached Figure 2 and attached Figure 4 As shown, the first swing arm 2 is rotatably mounted on the inner mounting seat 1 via the first rotating shaft 13, and the second swing arm 3 is rotatably mounted on the inner mounting seat 1 via the second rotating shaft 14. In this embodiment, the rotational connection between the swing arm and the inner mounting seat 1 is ensured, and the rotation is more flexible.
[0033] See attached Figure 3 and attached Figure 4 As shown, the first clamping jaw 4 is detachably arranged with the first swing rod 2, and the second clamping jaw 5 is detachably arranged with the second swing rod 3. In this embodiment, the clamping jaws are easily replaced, and the scope of use of the clamping mechanism is expanded.
[0034] See attached Figure 2 and attached Figure 4As shown, the interior of the inner mounting seat 1 is provided with a push rod 15 that can move up and down. The setting of the push rod 15 is convenient for pressing down the product, keeping the product stable, and facilitating the first clamping jaw 4 and the second clamping jaw 5 to clamp the product. The push rod 15 is connected to the telescopic end of the first linear cylinder 16, and is realized by the first linear cylinder 16 to achieve up and down movement; the outer mounting seat 6 is connected to the telescopic end of the second linear cylinder 17, and is realized by the second linear cylinder 17 to achieve up and down movement. The linear cylinder is used to achieve fast movement and high efficiency. There are two second linear cylinders 17, which are located on both sides of the inner mounting seat 1. Two linear cylinders are provided to drive the up and down movement of the outer mounting seat 6, and the movement is more efficient and stable.
[0035] See attached Figure 1 and attached Figure 3 As shown, the mounting end of the first linear cylinder 16, the mounting end of the second linear cylinder 17 and the inner fixing seat 18 are all fixed on a fixing seat 18. In this embodiment, the stability of the overall structure is guaranteed.
[0036] The clamping mechanism designed in this utility model can move downward through the outer mounting seat to achieve the clamping of the product by the first clamping jaw and the second clamping jaw. The clamping force gradually increases until the product is clamped. Even if the product is heavy, there is no risk of loosening.
