[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0025] Depend on Figures 1 to 3As shown, this utility model embodiment provides a positioning clamp mechanism with variable angle, including a base 1 and a first clamp seat 2. A rotating seat 3 is provided on the base 1. The first clamp is rotatably connected to the rotating seat 3 via a fixed shaft 4. A rotating component is coaxially fixed to the first clamp. The shaft 4 and the rotating seat 3 are connected by a bearing. The rotating component is fixed on the shaft 4. A driving assembly is provided on the base 1. The driving assembly is used to drive the rotating component to rotate, so that the first clamp seat 2 can drive the product mounted on the first clamp seat 2 to rotate relative to the base 1, thereby adjusting the product angle. The rotating component is a rotating gear 5. The driving assembly includes a rack and pinion slider 6, which meshes with the rotating gear 5. The base 1 is provided with a groove 22 suitable for sliding connection of the rack and pinion slider 6. Alternatively, it can be guided by a combination of guide rails and sliders, which will not be elaborated further here. When the rack and pinion slider 6 moves along the slide groove 22, the rotating gear 5 is driven to rotate by the meshing of the rack and pinion slider 6, thereby driving the first clamping seat 2 to rotate, so that the first clamping seat 2 and the product installed on the first clamping seat 2 rotate together relative to the base 1, adjusting the required angle to meet the various angles required by the product during processing.
[0026] Preferably, the drive assembly further includes a drive rod 7. A sliding hole 8 is provided on the base 1, and the drive rod 7 is slidably connected to the sliding hole 8. One end of the drive rod 7 abuts against the rack and pinion slider 6, and the other end passes through the sliding hole 8 and is provided with a rod head 9. By connecting an external drive mechanism (not shown in the figure) at the rod head 9, the drive rod 7 is controlled to move axially along the sliding hole 8, thereby pushing the rack and pinion slider 6 to move and drive the rotating gear 5 to rotate, adjusting the angle of the first clamp seat 2. Alternatively, the drive rod 7 and the sliding hole 8 can be reciprocated by a threaded connection, which will not be elaborated here.
[0027] Furthermore, in this embodiment, a first spring 10 is provided on the side of the rack slider 6 away from the drive rod 7. One end of the first spring 10 abuts against the rack slider 6, and the other end abuts against the inner wall of the groove. When the output end of the drive mechanism gradually moves away from the rod head 9, the first spring 10 can gradually push the rack slider 6 to reset, thereby resetting the first clamp seat 2. This embodiment is mainly used when the drive mechanism is not fixedly connected to the rod head 9, and is mainly used to push the drive rod 7. Of course, it can also be used as an auxiliary reset method in other fixed connection methods, which will not be elaborated here. Among them, the rack slider 6 at both ends of the first spring 10 and the inner wall of the groove can be provided with grooves to assist in limiting the first spring 10, or with pins, which will not be elaborated here.
[0028] In a preferred embodiment, a second spring 11 is provided between the rod head 9 and the base 1, and the second spring 11 is sleeved on the drive rod 7. By providing the second spring 11, the drive rod 7 can be assisted in moving away from the rack and pinion slider 6 and resetting.
[0029] The first clamping seat 2 includes a fixing part 12 and an adjusting part 13. The adjusting part 13 is configured to move closer to or further away from the fixing part 12, so that the first clamping seat 2 can clamp or release the product. In this embodiment, the fixing part 12 is a half-side clamping seat fixedly mounted on the shaft 4, with a second first clamping block 21 at its upper end; the adjusting part 13 is the other half-side clamping seat connected to the fixing seat by two rotating rods 15, with two second clamping blocks 14 at its upper end. The two half-side clamping seats form a complete set of clamping seats. By rotating the rotating rods 15, the half-side clamping seats of the adjusting part 13 can be moved closer to or further away from the fixing part 12. Clamping can also be achieved by connecting rods and springs, which will not be elaborated here. There are two complete sets of clamping seats, which are jointly mounted on the shaft 4, so that two products can be clamped.
[0030] Preferably, the clamping end of the first clamping block 21 is arc-shaped, which can easily adapt to products with curved surfaces and provide better clamping. The second clamping block 14 can be configured with a flat clamping end, so that one side of the clamping end of the first clamping seat 2 is suitable for clamping products with flat surfaces, and the other side is suitable for clamping products with curved surfaces, which can realize a point-to-surface cooperation method and increase the variety of products that can be clamped.
[0031] Preferably, the rotating base 3 is provided with a first limiting part 16 and a second limiting part 17. The first limiting part 16 is horizontally arranged, and the second limiting part 17 is vertically arranged. The first clamping base 2 can rotate 0-90° relative to the rotating base 3. In the initial state, the first clamping base 2 is placed on the first limiting part 16 in a horizontal state, and the installed product is at 0°. When the first clamping base 2 rotates to abut against the second limiting part 17, the installed product is at 90° relative to the initial rotation state. By limiting the rotation, the first clamping base 2 can be prevented from not exceeding 90°, and the clamping opening of the first clamping base 2 can be prevented from tilting downward, causing the product to fall out and be damaged.
[0032] In a preferred embodiment, a second clamping seat 18 is also provided on the base 1. The second clamping seat 18 is used to clamp the wire harness. The second clamping seat 18 is disposed in the limiting groove 19 on the base 1, and can be moved away from or close to the first clamping seat 2. A third spring 20 is provided on the first side of the second clamping seat 18 close to the first clamping seat 2, so that it tends to move away from the first clamping seat 2. The second clamping seat 18 is used to clamp the wire harness when the product has a wire harness, so as to position the wire harness. By first moving close to the first clamping seat 2 during clamping, and then moving away from it by the third spring 20, the wire harness can be kept in a tensile state, which facilitates the processing of the product. Further details are omitted here.
[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
