[0002] When performing machining operations such as drilling on the surface of a workpiece, tooling fixtures are usually used to position it first. However, for some irregularly shaped workpieces, fixed-position clamping and positioning modules are not flexible enough, have poor versatility, and are prone to inaccurate positioning, which affects the accuracy of machining operations. Utility Model Content

[0003] The purpose of this invention is to provide a universal fixture plate with a reasonable structure and reliable use and a quick-change positioning module, which solves the problem of poor universality of existing tooling fixtures for workpieces of different shapes. It can quickly change the positioning point according to the shape of the workpiece, making it flexible to use and accurate in positioning, thereby ensuring the precision of machining operations.

The lower part of the tube base is a square tube section inserted into the rectangular through slot; the support plate is in contact with the upper surface of the fixture plate body; the width of the limiting rod is less than the width of the rectangular through slot, and the length of the limiting rod is greater than the width of the rectangular through slot; the lower end of the positioning element points towards the upper surface of the fixture plate body.

[0005] The aforementioned universal fixture plate with quick-change positioning module has a positioning component that is a double-ended screw. The suspended plate has an arc-shaped elongated hole corresponding to the double-ended screw. The double-ended screw passes through the arc-shaped elongated hole and has an upper nut and a lower nut for clamping the suspended plate. A pressure plate is fixed to the lower end of the double-ended screw.

[0006] The aforementioned universal clamp plate with quick-change positioning module includes a spring assembly consisting of a spring fitted on the outside of the tube seat and a washer located on the upper end of the spring, with the upper surface of the washer in contact with the connecting plate.

[0007] In the aforementioned universal fixture plate with a quick-change positioning module, the suspended plate and the connecting plate are arranged concentrically, and an intermediate rod connects their centers.

[0012] The present invention will be described in detail with reference to the accompanying drawings.

[0013] like Figures 1-4 As shown, the universal fixture plate with quick-change positioning module includes a fixture plate body 7 and a quick-change positioning module. The number of quick-change positioning modules is multiple, selected according to positioning requirements.

[0014] In this embodiment, the fixture plate body 7 is provided with a plurality of rectangular through slots 12 that are parallel to each other. The rectangular through slots 12 extend from the left edge to the right edge of the fixture plate body 7, and each rectangular through slot 12 is evenly distributed from front to back on the fixture plate body 7.

[0015] The quick-change positioning module includes a tube base 16, a column 15 penetrating the central cavity of the tube base 16, a connecting plate 3 located at the upper end of the column 15, a support plate 5 located on the outer wall of the tube base 16, a spring assembly 4 sandwiched between the support plate 5 and the connecting plate 3, a limiting rod 6 located at the lower end of the column 15 and perpendicular to it, a suspended plate 1 located above the connecting plate 3, and a positioning element located at the edge of the suspended plate 1, the lower end of which points to the upper surface of the clamp plate body 7.

[0016] In this embodiment, the positioning component is a double-ended screw 8. The suspended disk 1 has an arc-shaped elongated hole 13 corresponding to the double-ended screw 8. The double-ended screw 8 passes through the arc-shaped elongated hole 13 and has an upper nut 9 and a lower nut 10 clamping the suspended disk 1. A pressure plate 11 is fixed to the lower end of the double-ended screw 8. The spring assembly 4 consists of a spring fitted on the outside of the tube seat 16 and a washer 14 located on the upper end of the spring. The upper surface of the washer 14 is in contact with the connecting disk 3. The suspended disk 1 and the connecting disk 3 are arranged concentrically, and an intermediate rod 2 connects their centers.

[0017] The lower part of the tube seat 16 is a square tube segment inserted into the rectangular through groove 12. The upper end of the square tube segment is connected to the support plate 5, and the support plate 5 is in contact with the upper surface of the clamp plate body 7. The lower end of the central cavity of the tube seat 16 is provided with an enlarged diameter port, and the lower end of the column 15 is provided with an axial limiting section that cooperates with the enlarged diameter port. The limiting rod 6 is located below the clamp plate body 7, and its width is smaller than the width of the rectangular through groove 12, while its length is greater than the width of the rectangular through groove 12.

[0018] Working principle: 1. When using, first place the workpiece to be processed on the fixture plate body 7, and then evenly arrange multiple quick-change positioning modules along its edge.

[0019] 2. The limiting rod 6 at the lower end of the quick positioning module is first parallel to the rectangular through groove 12, and then the square tube section is inserted into the rectangular through groove 12.

[0020] 3. When the external force presses down on the suspended plate 1, the connecting plate 3 pushes the spring assembly 4 downward, overcoming the supporting force of the spring assembly 4, so that the limiting rod 6 reaches below the fixture plate body 7. At the same time, the suspended plate 1 is rotated, which drives the limiting rod 6 to rotate 90 degrees synchronously and then releases the force, so that the limiting rod 6 is stuck below the fixture plate body 7, realizing the connection and positioning of the module and the fixture plate body 7. At this time, the spring assembly 4 is in a compressed state and will not shake due to external force during operation.

[0021] 4. Adjust the position of the positioning component on the suspended plate 1 so that the pressure plate 11 is directly opposite the edge of the workpiece. Adjust the longitudinal position of the positioning component so that the pressure plate 11 presses onto the workpiece, and then lock and fix it.

[0022] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
