Description

Technical Field

[0001] This utility model belongs to the field of clamping equipment, and specifically relates to a multi-degree-of-freedom rapid positioning tooling fixture. Background Technology

[0002] Positioning fixtures are specialized process equipment used in industrial production to fix the position of workpieces and ensure their stability during machining, assembly, and inspection processes. Currently, positioning fixtures suffer from limited adaptability in practical applications. Their positioning references are often based on fixed designs specific to the workpiece structure, resulting in a narrow compatibility range for irregularly shaped or multi-specification workpieces and difficulty in flexibly matching the spatial position requirements of different processes. To adapt to multi-variety production, the conventional approach is to customize special fixtures for different workpieces or to repeatedly calibrate and adjust them manually. However, special fixtures not only increase design and manufacturing costs but also occupy a large amount of inventory space. Furthermore, frequent fixture changes lead to prolonged machine tool downtime, significantly reducing equipment utilization. Therefore, a new structure is needed to solve the aforementioned technical problems. Utility Model Content

[0005] In a preferred embodiment, multiple support legs are evenly installed on the left and right edges of the lower surface of the table body. A magnet is installed at the bottom inside the fixing hole on the upper surface of the table body. The diameter of the fixing hole matches the diameter of the fixing rod, and the length of the fixing hole matches the length of the fixing rod. In use, multiple workpieces are simultaneously clamped and fixed by multiple sets of fixtures to achieve batch processing, assembly, or inspection, which greatly shortens the overall processing cycle of a single batch of workpieces. At the same time, with the installation components, the fixture components can be adjusted with multiple degrees of freedom to flexibly adapt to the multi-process processing requirements of workpieces of the same specifications, further improving the versatility of tooling fixtures and the adaptability of automated production lines.

[0019] 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.

[0020] Please see Figures 1 to 3As the first embodiment of this utility model: a multi-degree-of-freedom rapid positioning tooling fixture, including: an installation component and a clamping component. The upper surface of the installation component is uniformly equipped with multiple sets of clamping components for clamping and fixing. The multiple sets of clamping components have the same structure. The installation component includes a table 100. The upper surface of the table 100 is uniformly provided with multiple fixing holes 101 for magnetic fixing. The clamping component includes clamp one and clamp two. Clamp one and clamp two are respectively installed on the left side surface and the right side surface of the installation plate 200.

[0021] Multiple support legs 110 are evenly installed on the left and right edges of the lower surface of the table body 100. A magnet is installed at the bottom inside the fixing hole 101 on the upper surface of the table body 100. The diameter of the fixing hole 101 matches the diameter of the fixing rod 201, and the length of the fixing hole 101 matches the length of the fixing rod 201.

[0022] A fixing rod 201 is welded to the center of the lower surface of the mounting plate 200. A magnet 2 is installed at the end of the fixing rod 201 away from the mounting plate 200. The magnet 2 has the same structure as the magnet 1. The magnet 1 and the magnet 2 are magnetically connected. The lower surface of the mounting plate 200 abuts against the upper surface of the table body 100 (initially there is a gap between the clamping plate and the mounting plate 200, and it abuts against the workpiece when clamping).

[0023] In use, the user places the workpiece to be clamped on the upper surface of the table 100. After the workpiece is placed, the user can remove multiple sets of clamping assemblies. After removing the clamping assemblies, the user can align the fixing rod 201 on the lower surface of the clamping assembly with the fixing hole 101 on the upper surface of the table 100. At this time, the workpiece on the upper surface of the table 100 will block the fixing hole 101, but the outer edge of the workpiece will protrude from the fixing hole 101 (only applicable to workpieces smaller than the table 100 with protruding fixing holes at the edges). Then, the fixing rod 201 on the lower surface of the clamping assembly will be inserted into the fixing hole 101, so that the magnet one inside the fixing hole 101 is magnetically connected to the magnet two at the lower end of the fixing rod 201 (the specific details of magnet one and magnet two are as follows). Users can choose permanent magnets to avoid demagnetization caused by repeated insertion and removal. The size of the magnetic attraction can be selected by the user based on the materials of magnet one and magnet two (details not elaborated here). The clamping assembly is then magnetically attached to the upper surface of the table 100. At this time, the clamping assembly is set around the workpiece at different angles, and the workpiece is clamped and fixed by the clamping assembly. During use, multiple sets of clamps are used to simultaneously clamp and fix multiple workpieces, realizing batch processing, assembly or inspection, which greatly shortens the overall processing cycle of a single batch of workpieces. At the same time, with the installation components, the clamping assembly can be adjusted with multiple degrees of freedom to flexibly adapt to the multi-process processing requirements of workpieces of the same specifications, further improving the versatility of tooling fixtures and the adaptability of automated production lines.

[0024] Please see Figures 1 to 3 As a second embodiment of this utility model: based on the description in the above embodiments, the mounting plate 200 is further fixed to the upper surface of the table body 100 by magnetic snap-fit ​​of the fixing rod 201. The clamp includes a slider 220, a fixing block 240 and a rotating rod 260. A slide rail 210 is installed at the center of the left side surface of the mounting plate 200. The slider 220 is slidably installed on the left side surface of the slide rail 210. A clamping block 230 is installed on the upper side surface of the slider 220. The upper side surface of the clamping block 230 is provided with anti-slip ridges 231.

[0025] A fixing block 240 is mounted on the top of the slider 220 via a mounting plate 200. The structure of the fixing block 240 matches the structure of the slider 220. A clamping block 230 with the same structure as the upper surface of the slider 220 is mounted on the lower surface of the fixing block 240. A rotating rod 260 is movably and through the center of the upper surface of the fixing block 240.

[0026] A rocker arm 270 is installed at the upper end of the rotating rod 260, and the lower end of the rotating rod 260 moves through the slider 220. The contact surface between the rotating rod 260 and the slider 220 is provided with threads. The slider 220 moves along the slide rail 210 through the rotating rod 260. The second clamp includes a connecting plate 280 and a clamping rod 290.

[0027] An L-shaped connecting plate 280 is integrally formed on the upper edge of the right side surface of the mounting plate 200. A clamping rod 290 is threaded through the right side surface of the connecting plate 280. A clamping plate and a knob are respectively installed on the left and right ends of the clamping rod 290. The inner surface of the clamping plate abuts against the right side surface of the mounting plate 200.

[0028] In use, after the fixture assembly is installed through the operation of the first embodiment (it is not limited to placing the workpiece first and then installing the fixture assembly; the fixture assembly can also be installed first, and then the workpiece can be clamped inside the fixture assembly), the user can select fixture one and fixture two according to actual needs. When using fixture one, the workpiece is between the two clamping blocks 230 (the thickness of the workpiece being clamped must be less than the movement path of the slider 220; otherwise, this device is not suitable for this workpiece; the same applies to fixture two). At this time, the user can rotate the rotating rod 260 through the crank handle 270, causing the rotating rod 260 to drive the slider 220 to move along the slide rail 210, thereby causing the two clamping blocks 230 to move towards each other, thus clamping and fixing the workpiece between the two clamping blocks 230. Thus, the workpiece is clamped by fixture one. When clamping the workpiece with fixture two, the user can place the workpiece on the inner surface of the connecting plate 280. After the workpiece is on the inner surface of the connecting plate 280, the user can rotate the clamping rod 290, causing the clamping rod 290 to... The workpiece is clamped on the inner surface of the connecting plate 280, thus achieving the effect of clamping the workpiece through the second clamp. Regardless of whether the workpiece is clamped by the first or the second clamp, the user can clamp the workpiece at different angles on the upper surface of the table 100 during installation. After the workpiece is clamped and fixed by multiple clamp components, the workpiece will not shake due to the mutual restraint and fixation of multiple clamp components, thus achieving a stable clamping effect for the workpiece, which is convenient for the user. During use, the clamp components can achieve synchronous or independent clamping on both sides. It can simultaneously fix two workpieces of the same specification. Relying on the multi-degree-of-freedom function (the clamp components rotate around the Z-axis of the fixing hole 101 through the fixing rod 201, thus forming a multi-degree-of-freedom clamping effect through multiple clamp components), the posture of the workpieces on both sides can be adjusted synchronously to improve batch processing efficiency. It can also be used for special workpieces such as single long strips and symmetrical structures. Stable clamping points can be formed by the double-sided clamps to avoid workpiece deformation or positioning displacement caused by single-sided clamping, ensuring clamping stability and positioning accuracy.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
