Elbow clamps are commonly used clamping mechanisms in automotive parts assembly, offering advantages such as simple structure and ease of use. However, conventional elbow clamps can only clamp along a fixed trajectory using either oscillating or linear motion, failing to meet the requirements for clamping irregularly shaped workpieces along specific trajectories. Therefore, how to accurately and efficiently assemble irregularly shaped workpieces has become an urgent problem to be solved in enterprise production processes. Utility Model Content

Detailed Implementation
[0023] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0024] Example
[0025] like Figure 1 and Figure 2 As shown, the present invention provides a combined pressing device capable of moving according to a set trajectory, comprising a sliding component 10, a pressing arm mechanism 20, a locking mechanism 30, and a trajectory setting mechanism 40, wherein the pressing arm mechanism 20 and the trajectory setting mechanism 40 are mounted on the sliding component 10, and the locking mechanism 30 is mounted on the trajectory setting mechanism 40.
[0026] like Figure 3As shown, the sliding assembly 10 includes a fixed base plate 11, on which a first-layer linear guide rail 12 is fixedly mounted. Slider limiters 18 are installed at both ends of the first-layer linear guide rail 12 to prevent the sliders from sliding out. A first-layer sliding plate 13 is movably mounted on the first-layer linear guide rail 12. The lower part of the first-layer sliding plate 13 is fixedly connected to the slider on the first-layer linear guide rail 12, allowing the first-layer sliding plate 13 to slide on the first-layer linear guide rail 12. A second-layer linear guide rail 14 is mounted on the first-layer sliding plate 13. The second-layer linear guide rail 14 is perpendicular to the direction of the first-layer linear guide rail 12, and slider limiters 18 are also installed at both ends of the second-layer linear guide rail 14 to prevent the sliders from sliding out. A second-layer sliding plate 15 is movably mounted on the second-layer linear guide rail 14. The lower part of the second-layer sliding plate 15 is fixedly connected to the slider on the second-layer linear guide rail 14, allowing the second-layer sliding plate 15 to slide on the second-layer linear guide rail 14. The second sliding plate 15 is equipped with a sliding handle 16 and a locking pin block 17. The sliding handle 16 is used to drive the second sliding plate 15 to move arbitrarily in the plane along the two guide rail directions. The locking pin block 17 is used to cooperate with the locking mechanism 30 to complete the pressing and locking. The second sliding plate 15 also has reserved holes for installing the pressure arm mechanism 20.
[0027] like Figure 4 As shown, the pressure arm mechanism 20 includes a fixed base 21. One end of the fixed base 21 has mounting holes corresponding to the holes on the second sliding plate 15, allowing the fixed base 21 and the second sliding plate 15 to be fixedly connected by bolts or screws. A linear bearing 24 is mounted on the side of the fixed base 21 facing the workpiece to be pressed, and a pressure head 22 is mounted on the other side. The pressure head 22 passes through the fixed base 21 and is fitted with the linear bearing 24. A pressure arm spring 23 is fitted onto the pressure head 22, with both ends of the spring contacting the fixed base 21 and the pressure head 22 respectively, allowing the pressure head 22 to slide within the linear bearing 24.
[0028] like Figure 6 As shown, the trajectory setting mechanism 40 includes a mounting bracket 41, which is fixedly mounted on a fixed base plate 11. A sliding trajectory plate 42 is mounted on the mounting bracket 41. The sliding trajectory plate 42 is located above the sliding assembly 10 and the pressure arm mechanism 20. The sliding trajectory plate 42 has grooves machined on it, corresponding to the set trajectory that the workpiece needs to move when pressed, and the sliding handle 16 passes through the grooves. The sliding trajectory plate 42 also has mounting holes for mounting a locking mechanism.
[0029] like Figure 5As shown, the locking mechanism 30 includes a fixed sleeve 31, which is installed on the mounting hole of the sliding track plate 42. The fixed sleeve 31 is positioned opposite the locking pin block 17. A sliding groove is machined vertically on the fixed sleeve 31, and a locking groove is formed at the bottom of the sliding groove. The opening direction of the locking groove forms an angle greater than or equal to 90° with the sliding groove, which facilitates the self-locking function. A sliding shaft 32 is installed inside the fixed sleeve 31, and a locking handle 34 is installed on the sliding shaft 32. The locking handle 34 can slide along the sliding groove and form a self-locking in the locking groove. A locking spring 33 is fitted on the sliding shaft 32, and the two ends of the locking spring 33 contact the top of the sliding shaft 32 and the sliding track plate 42 respectively, so that the sliding shaft 32 can move upward automatically when unlocked. When the sliding shaft 32 moves downward, it can pass through the sliding track plate 42 and insert into the locking pin block 17 to complete the locking of the sliding assembly 10.
[0030] The working process of the combined pressing device of this utility model, which can move according to a set trajectory, is as follows: the sliding handle 16 of the movable sliding component 10 can move within the set trajectory of the sliding trajectory plate 42 in the trajectory setting mechanism 40; when the sliding handle 16 moves to the locking position within the trajectory, the pressing head 22 in the pressing arm mechanism 20 presses the product; after pressing, the pressing head 22 pushes the pressing spring 23, so that the pressing head 22 can slide within the linear bearing 24, giving the pressing head 22 a certain size tolerance function; after the pressing arm mechanism 20 presses the product, by pushing the locking handle 34 in the locking mechanism 30 to the locking groove position of the fixed sleeve 31, the sliding shaft 32 is inserted into the locking pin block 17 hole in the sliding component 10 to complete the pressing and locking.
[0031] When different trajectory requirements need to be met for the pressing action, simply change the trajectory of the slide groove on the sliding trajectory plate 42 inside the trajectory setting mechanism 40.
[0032] This utility model discloses a combined pressing device capable of moving along a set trajectory. The sliding component enables the sliding plate to move in any direction within a plane; the pressing mechanism, fixed on the sliding component, enables product pressing; the locking mechanism enables positioning and locking after the sliding plate is in place; and the trajectory design mechanism enables the sliding mechanism to press the product according to the designed trajectory.
[0033] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
