Description

Technical Field

[0001] This utility model relates to the field of positioning fixture technology, and in particular to a high-precision stamping feeding positioning fixture. Background Technology

[0002] According to Chinese Patent No. CN222094545U, this utility model is a positioning device for a stamping machine worktable, including a support assembly. The support assembly includes a work platform, a rotating disk rotatably connected to the surface of the work platform, a positioning seat fixedly connected to the surface of the rotating disk, and two double-threaded screws rotatably connected to the surface of the positioning seat. Moving blocks are threadedly connected to the surfaces of the double-threaded screws, and clamping plates are fixedly connected to the surfaces of the moving blocks. A drive mechanism for driving the double-threaded screws is installed on the surface of the positioning seat. The drive mechanism drives the two double-threaded screws to rotate, which in turn drives multiple moving blocks to move, thereby moving two clamping plates inward to clamp and fix molds of different sizes. The rotating disk is rotated by the rotating mechanism, thereby adjusting the angle of the mold. Subsequently, the extended end of the electric telescopic rod drives the stamping template to stamp. Positioning different molds takes less time, improving work efficiency.

[0003] The aforementioned prior art and related documents have the following technical problems:

[0004] Traditional feeding and positioning fixtures often suffer from problems such as inaccurate positioning, uneven clamping force, and inconvenient operation. These issues can easily lead to the displacement and deformation of stamping materials during processing, thereby reducing the product qualification rate and increasing production costs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-precision stamping feeding and positioning fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-precision stamping feeding and positioning fixture, comprising a platform, positioning blocks on both sides of the platform, positioning bolts on the top of the positioning blocks, an adjusting screw at the bottom of the platform, a clamping cylinder on one side of the adjusting screw, a moving block on the top of the adjusting screw, a telescopic rod on the front of the moving block, a clamping plate on the front of the telescopic rod, and a pressure sensor on one side of the clamping plate.

[0007] Preferably, the top of the platform is provided with a precision scale marker, and the bottom of the precision scale marker is welded to the top of the platform.

[0008] Preferably, the front of the pressure sensor is provided with a rubber pad layer, and the rubber pad layer is bonded to the pressure sensor.

[0009] Preferably, the platform has a positioning plate at its center, and the positioning plate is fitted into the center of the platform.

[0010] Preferably, the top of the positioning plate is provided with a positioning pin, and the top of the positioning pin is rounded, and the positioning pin is arranged in a circumferential array.

[0011] Preferably, the bottom of the positioning plate is provided with a rotary cylinder, and the rotary cylinder is threadedly connected to the positioning plate.

[0012] Preferably, the bottom of the rotary cylinder is provided with a limiting frame, and the limiting frame and the rotary cylinder are fitted together, and the limiting frame and the platform are welded together.

[0013] Beneficial effects

[0014] In this invention, a rubber pad is provided on one side of the telescopic rod, with a pressure sensor located in the middle of the rubber pad. The rubber material has good elasticity and wear resistance, protecting the surface of the stamping material during clamping. This allows for the detection of the clamping force, and the signal is fed back to the control system for precise clamping force control. The elasticity of the rubber pad buffers the pressure of the clamping plate on the stamping material. During clamping, when the clamping plate approaches the stamping material, the rubber pad first contacts the material surface. Because rubber can deform to a certain extent, it can conform to the slight unevenness of the material surface, avoiding scratches, indentations, and other damage caused by hard contact between the clamping plate and the material surface. By detecting the clamping force through the pressure sensor and feeding it back to the control system, the magnitude of the clamping force can be precisely adjusted. This ensures that the clamping force remains within a stable range that meets the process requirements each time the stamping material is clamped.

[0015] In this invention, a positioning plate is embedded in the center of the platform, and a positioning pin is provided on the top of the positioning plate to achieve initial positioning of the stamping material. A rotary cylinder is provided at the bottom of the positioning plate, which can drive the positioning plate to rotate for precise positioning. By driving the positioning plate to rotate, the angle and direction of the stamping material can be precisely adjusted. In the processing of some complex-shaped or specially angled stamped parts, this method can ensure that the material is positioned at the optimal angle. For some automotive parts with asymmetrical shapes or that need to be stamped at specific angles, such as irregular brackets, the rotary positioning plate can accurately adjust the material to the appropriate processing angle, effectively improving stamping accuracy.

[0016] In this invention, a precise scale marker is installed on the top of the platform, providing an intuitive positional reference for positioning operations. Operators can accurately adjust the position of the stamping material according to the scale, ensuring its placement on the platform is accurate to millimeters or even smaller units. Thus, when manufacturing precision electronic component stampings, where material positioning requires micron-level precision, the scale marker helps operators control the material's placement error within an extremely small range.

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-4A high-precision stamping feeding and positioning fixture includes a platform 1, with positioning blocks 11 on both sides of the platform 1, positioning pins 12 on the top of the positioning blocks 11, a precision scale marker 8 on the top of the platform 1, the bottom of the precision scale marker 8 being welded to the top of the platform 1, a positioning plate 9 at the center of the platform 1 being fitted into the center of the platform 1, a positioning pin 10 on the top of the positioning plate 9 with rounded corners, the positioning pins 10 being arranged in a circumferential array, and a rotary cylinder 13 at the bottom of the positioning plate 9. The positioning plate 9 is connected by threads. The bottom of the rotary cylinder 13 is provided with a limit frame 14, and the limit frame 14 and the rotary cylinder 13 are fitted together. The limit frame 14 and the platform 1 are welded together. The bottom of the platform 1 is provided with an adjusting screw 3. A clamping cylinder 2 is provided on one side of the adjusting screw 3. A moving block 4 is provided on the top of the adjusting screw 3. A telescopic rod 5 is provided on the front of the moving block 4. A clamping plate 15 is provided on the front of the telescopic rod 5. A rubber pad 7 is provided on the front of the pressure sensor 6, and the rubber pad 7 and the pressure sensor 6 are fitted together. A pressure sensor 6 is provided on one side of the clamping plate 15.

[0027] A rubber pad 7 is provided on one side of the telescopic rod 5, and a pressure sensor 6 is located in the middle of the rubber pad 7. The rubber material has good elasticity and wear resistance, which protects the surface of the stamping material during the clamping process. This allows the clamping force to be detected and the signal to be fed back to the control system for precise control of the clamping force. The elasticity of the rubber pad 7 can buffer the pressure of the clamping plate 15 on the stamping material. During the clamping process, when the clamping plate 15 approaches the stamping material, the rubber pad 7 is the first to contact the material surface. Because rubber can deform to a certain extent, it can conform to the slight unevenness of the material surface, avoiding scratches, indentations, and other damage caused by hard contact between the clamping plate 1515 and the material surface. The clamping force is detected by the pressure sensor 6 and fed back to the control system, allowing for precise adjustment of the clamping force. This ensures that the clamping force remains within a stable range that meets process requirements each time the stamping material is clamped. A positioning plate 9 is embedded in the center of the platform 1, with a positioning pin 10 on its top for initial positioning of the stamping material. A rotary cylinder 13 is located at the bottom of the positioning plate 9, allowing for precise positioning by rotating the positioning plate 9. The rotation of the positioning plate 9 by the rotary cylinder 13 enables precise adjustment of the angle and direction of the stamping material. In the processing of stamped parts with complex shapes or special angle requirements, this method ensures that the material is positioned at the optimal angle. For automotive parts with asymmetrical shapes or requiring stamping at specific angles, such as irregularly shaped brackets, the rotary positioning plate 9 can precisely adjust the material to the appropriate processing angle, effectively improving stamping accuracy. A precision scale marker 8 is installed on the top of the platform 1, providing an intuitive positional reference for the positioning operation. Operators can accurately adjust the position of the stamping material according to the scale, ensuring its placement on the platform 1 is accurate to millimeters or even smaller units. Thus, when manufacturing precision electronic component stampings, where material positioning requires micron-level precision, the scale marker helps operators control the material's placement error within an extremely small range.

[0028] First, the stamping material is placed on the positioning plate 9 and initially positioned using the positioning pin 10. Then, the clamping cylinder 2 is activated, and the clamping plate 15 clamps the stamping material under the push of the adjusting screw 3. The pressure sensor 6 monitors the clamping force in real time and feeds the signal back to the control system. When the clamping force reaches the set value, the clamping cylinder 2 stops operating. If it is necessary to adjust the position of the stamping material, the adjusting screw 3 can be rotated, and the movement distance of the positioning plate 9 on the platform 1 can be precisely controlled according to the precision scale marker 8, thereby achieving high-precision feeding and positioning. Specific Implementation Example 2:

[0030] Reference Figure 1-4A retractable gripper is added to the top of the positioning plate 9. The retractable gripper can automatically adjust according to the size of the stamping material. Whether the material is large or small, the gripper can extend and retract to fit tightly against the edge of the material, achieving precise positioning. High-precision screw drive or electric push rod is used to drive the gripper to extend and retract, which can control the positioning accuracy within a very small range.

[0031] In summary:

[0032] A rubber pad 7 is provided on one side of the telescopic rod 5, and a pressure sensor 6 is located in the middle of the rubber pad 7. The rubber material has good elasticity and wear resistance, which protects the surface of the stamping material during clamping. This allows the clamping force to be detected and the signal to be fed back to the control system for precise control of the clamping force. The elasticity of the rubber pad 7 can buffer the pressure of the clamping plate 15 on the stamping material. During the clamping process, when the clamping plate 15 approaches the stamping material, the rubber pad 7 first contacts the material surface. Because rubber can deform to a certain extent, it can conform to the slight unevenness of the material surface, avoiding scratches, indentations and other damage caused by hard contact between the clamping plate 15 and the material surface. The pressure sensor 6 detects the clamping force and feeds it back to the control system, which can accurately adjust the clamping force. This ensures that the clamping force is kept within a stable range that meets the process requirements each time the stamping material is clamped.

[0033] A positioning plate 9 is embedded in the center of platform 1, with a positioning pin 10 on top of the positioning plate 9, achieving initial positioning of the stamping material. A rotary cylinder 13 is located at the bottom of the positioning plate 9, which can drive the positioning plate 9 to rotate for precise positioning. The rotation of the positioning plate 9 by the rotary cylinder 13 allows for precise adjustment of the angle and direction of the stamping material. In the processing of stamped parts with complex shapes or special angle requirements, this method ensures that the material is positioned at the optimal angle. For automotive parts with asymmetrical shapes or requiring stamping at specific angles, such as irregularly shaped brackets, the rotary positioning plate 9 can precisely adjust the material to the appropriate processing angle, effectively improving stamping accuracy.

[0034] A precision scale marker 8 is installed on the top of platform 1, providing an intuitive positional reference for positioning operations. Operators can accurately adjust the position of the stamping material according to the scale, ensuring its placement on platform 1 is accurate to millimeters or even smaller units. This is particularly useful when manufacturing precision electronic component stampings, where material positioning requires micron-level precision; the scale marker helps operators control the material's placement error within an extremely small range.
