Description

Technical Field

[0001] This utility model relates to the field of mechanical tool technology, specifically to a tooling fixture rotation device. Background Technology

[0002] Existing tooling fixture rotation devices require manual adjustment of the fixture, which is time-consuming and labor-intensive. They need to be assembled at different angles and rotated after clamping, making the operation complex. Manual operation is prone to errors, such as unclear rotation direction or insufficient clamping force. Therefore, a new tooling fixture rotation device has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0003] This utility model provides a tooling fixture rotation device for rotating a workpiece after clamping it, comprising:

[0004] Support plate;

[0005] A rotating assembly is installed at the bottom end of the support plate, and the rotating assembly drives the support plate to rotate;

[0006] An electromagnetic chuck, located at the top of the support plate, is used to provide electromagnetic attraction.

[0007] Several clamping assemblies are located at the top of the electromagnetic chuck and are used to clamp the workpiece. The clamping assemblies are connected to the electromagnetic chuck.

[0008] Optionally, the electromagnetic chuck has a cross-shaped structure, and an iron core and coil are provided inside the electromagnetic chuck. When energized, the electromagnetic chuck attracts the clamping assembly to form a fixed structure.

[0009] Optionally, the electromagnetic chuck has grooves on its cross-shaped structure, and the grooves are adapted to the clamping assembly.

[0010] Optionally, four clamping assemblies are provided, respectively arranged in the four directions of the cross-shaped structure of the electromagnetic chuck. Each clamping assembly includes a support, a slider, and a flexible pin. The slider is located at the bottom of the support, and the flexible pin is located on the support.

[0011] Optionally, the support is configured as an L-shape, with the four supports sliding toward the intersection of the cross-shaped structure of the electromagnetic chuck, and clamping the workpiece after sliding to an adaptive position on the slide groove.

[0012] Optionally, the elastic pins are provided in a plurality of them, densely arranged at the intersection of the cross-shaped structure of the support facing the electromagnetic chuck.

[0013] Optionally, the elastic pin has a back plate, an elastic part, and a support part. The back plate has several support holes at positions that are compatible with the elastic part. The elastic part is installed inside the support holes. One end of the elastic part is connected to the bottom end of the support hole, and the other end is connected to the support part. One end of the support part is connected to the elastic part, and the other end is used to contact the workpiece.

[0014] The beneficial effects of this application are as follows:

[0015] 1. This utility model provides a synergistic adjustment structure for a cross-shaped electromagnetic chuck and a sliding clamping assembly. By designing the electromagnetic chuck as a cross-shaped structure with a sliding groove on its surface, and combining it with an L-shaped support with a slider at the bottom, the clamping assembly achieves four-way position adjustment. This structure breaks through the limitations of traditional fixed clamps, allowing the clamping assembly to slide freely along the cross-shaped sliding groove before being energized and fixed, thus precisely matching the clamping requirements of workpieces of different sizes. Compared to traditional separate clamps, this design integrates the electromagnetic chuck and mechanical sliding into one unit, retaining the convenience of electromagnetic quick locking while giving the clamp self-adjusting capability, making it suitable for flexible production lines with multiple varieties and small batches.

[0016] 2. This utility model provides a multi-level buffer clamping system for elastic pins, employing a three-level elastic pin structure consisting of a back plate, an elastic part, and a support part. Dynamic pressure compensation is achieved through the compression deformation of the elastic element within the support hole. The densely arranged elastic pin group forms a distributed flexible contact surface, which is a significant improvement over the single-point pressure mode of traditional rigid clamps.

[0021] 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.

[0022] like Figure 1 As shown, the support plate 1 is made of high-strength aluminum alloy, and its bottom is connected to the drive end of the rotating component 2 through a flange. The rotating component 2 has a built-in servo motor and reducer, which can achieve precise indexing rotation from 0 to 360°.

[0023] The electromagnetic chuck 3 is fixed to the upper surface of the support plate 1 by bolts. Each arm of its cross-shaped structure is machined with a T-shaped groove 5, and a linear bearing is embedded in the groove to reduce the coefficient of friction.

[0024] Please refer to the following: Figure 2-3 As shown, four clamping assemblies 4 are symmetrically arranged at the four ends of the electromagnetic chuck 3. A slider 7 is welded to the bottom of the L-shaped support 6 of each clamping assembly 4. The flange of the slider 7 matches the cross-section of the slide groove 5, allowing linear movement along the slide groove 5.

[0025] The support 6 has a back plate 9 installed on its vertical sidewall. The back plate 9 has a matrix of support holes 12, and each hole is fitted with an elastic pin 8.

[0026] The elastic pin 8 has a back plate 9, an elastic part 10, and a support part 11. The back plate 9 has several support holes 12 at positions that are compatible with the elastic part 10. The elastic part 10 is installed inside the support holes 12. One end of the elastic part 10 is connected to the bottom end of the support hole 12, and the other end is connected to the support part 11. One end of the support part 11 is connected to the elastic part 10, and the other end is used to contact the workpiece.

[0027] The elastic part 10 is a stainless steel helical spring, one end of which is welded to the bottom of the support hole 12, and the other end is connected to the hemispherical support part 11. The surface of the support part 11 is sandblasted and covered with a polyurethane anti-slip layer.

[0028] During operation, first disconnect the power to release the magnetic force of the electromagnetic chuck 3, then slide the clamping assembly 4 along the slide groove 5 to a position that matches the workpiece size. Figure 1As shown. After the workpiece is placed in the positioning area surrounded by the four clamping components 4, the electromagnetic chuck 3 is energized to generate a strong magnetic attraction, causing the slider 7 and the groove 5 to form a magnetic attraction and lock. At this time, the support part 11 of the elastic pin 8 is pressed tightly against the surface of the workpiece under the action of the spring, forming a multi-contact flexible clamping. After the rotating component 2 is started, the support plate 1 drives the entire workpiece to rotate to the processing angle.

[0029] For thin-walled, easily deformable workpieces, the suction force can be adjusted by reducing the input current of the electromagnetic chuck 3 to avoid over-clamping and deformation of the workpiece. This device is particularly suitable for multi-process machining scenarios of workpieces such as electronic component housings and irregularly shaped stamped parts.

[0030] The above description is merely a few embodiments of this application and is not intended to limit this application in any way. Although this application discloses preferred embodiments as described above, it is not intended to limit this application. Any changes or modifications made by those skilled in the art without departing from the scope of the technical solution of this application using the disclosed technical content are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
