Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to an elastic clamping centering device for turning metal blanks. Background Technology

[0002] In the metalworking industry, turning is a key process for achieving precise forming of metal blanks. Precise centering of the metal blank is an indispensable step before turning, and its centering accuracy directly affects the dimensional accuracy, form and position tolerances, and surface quality of the subsequently machined parts. "An elastically clamping metal blank turning centerer," a centering device specifically designed for metal blank turning, was developed to meet the demands of efficient and precise centering. Through innovative structural design, it aims to improve the positioning stability and reliability of the metal blank during turning, providing a solid foundation for high-quality turning.

[0003] In existing technologies, equipment used for centering metal blanks during turning often employs rigid clamping and positioning structures. For example, some common centering equipment uses pneumatically or hydraulically driven rigid clamps. The clamps are driven by a power source to clamp and position the metal blank. The technical principle is mainly based on the forced displacement of the clamps to fix the blank, and the rigid constraint of the mechanical structure ensures that the blank does not shift during the machining process.

[0004] However, due to the inevitable dimensional deviations, irregular shapes, or uneven surfaces that occur in the early production processes such as casting and forging of metal blanks, existing centering equipment with rigid clamping structures cannot adaptively adjust according to the actual condition of the blank. During the clamping process, the centering center is prone to offset from the actual geometric center of the blank due to the deviation of the blank itself, which in turn affects the accuracy of subsequent turning operations. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an elastic clamping centering device for turning metal blanks, which aims to improve the problem that traditional equipment is unable to cope with the deviation of metal blanks, resulting in centering offset.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an elastic clamping centering device for turning metal blanks, comprising a base, a chassis above the base, an elastic centering component above the chassis, and a height adjustment component on the inner wall of the base;

[0007] The elastic centering assembly includes a clamping rod, the outer wall of which is disposed above the chassis. A turntable is rotatably connected to the inner wall of the chassis. A steering rod is fixedly connected to the upper surface of the chassis. A sliding rod is fixedly connected to the upper surface of the turntable. A rotation groove is formed in the inner wall of the chassis. The outer wall of the steering rod is rotatably connected to the inner wall of the clamping rod. A first hole groove is formed in the inner wall of the clamping rod. An elastic claw head is fixedly connected to the outer wall of the clamping rod. A fixing block is fixedly connected to the upper surface of the chassis. A nut is fitted to the outer wall of the fixing block. A screw is threadedly connected to the inner wall of the nut. A limit block is rotatably connected to the outer wall of the screw. A second hole groove is formed in the inner wall of the limit block. A clamping piece is rotatably connected to the outer wall of the limit block.

[0008] Furthermore, the height adjustment component includes a trapezoidal block, the outer wall of which is slidably connected to the inner wall of the base, a connecting rod fixedly connected to the inner wall of the trapezoidal block, a sliding groove one, a hole groove three, a hole groove four, a sliding groove two, a support rod fixedly connected to the lower surface of the chassis, and a locking plate slidably connected to the inner wall of the base.

[0009] Furthermore, the outer wall of the turntable is rotatably connected to the inside of the rotating groove, which provides rotational guidance for the turntable while also limiting its movement.

[0010] Furthermore, the steering rod is rotatably connected inside the slot, the slide rod is slidably connected to the inner wall of the clamping rod, and the elastic claw head is made of silicone.

[0011] Furthermore, the inner wall of the clamping piece is fixedly connected to the outer wall of the turntable, and the outer wall of the screw is threadedly connected to the inner wall of the second slot.

[0012] Furthermore, the outer wall of the screw is slidably connected to the inner wall of the fixing block, and the fixing block is used to fix the position of the screw.

[0013] Furthermore, the outer wall of the trapezoidal block is slidably connected to the inner wall of the second slide groove, the outer wall of the support rod is slidably connected to the inner wall of the fourth slot, and the outer wall of the connecting rod is slidably connected to the inner wall of the first slide groove.

[0014] Furthermore, the outer wall of the card plate is slidably connected to the inner wall of the slot three, and the card plate is used to lock the position of the trapezoidal block.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by rotating the screw outward, the limiting block moves away from the fixed block, driving the turntable to rotate, causing the clamping rod to rotate in the slot, increasing the clamping diameter, placing the metal blank in the center of the chassis, and then reversing the above steps to firmly clamp the metal blank with the elastic claw. The elastic claw undergoes uniform deformation, determining the geometric center of the metal blank. This solves the problem that traditional equipment cannot handle deviations in the metal blank, which leads to centering offset, and achieves a more accurate positioning of the geometric center of the part.

[0017] 2. In this utility model, by pushing the connecting rod, the trapezoidal block slides in the second groove, and the pressing support rod slides upward in the fourth hole, driving the chassis to move upward. After adjusting to a suitable height, the clamping plate is inserted into the third hole that is close to the connecting rod to lock the height of the chassis. This eliminates the need to constantly hold the workpiece to correct its position, reducing operational inconvenience and improving operational efficiency. Attached Figure Description

The inner wall of the nut 12 is threadedly connected to a screw rod 11. The fixing block 10 is used to fix one end of the screw rod 11 and provide support for the screw rod 11. The outer wall of the screw rod 11 is rotatably connected to a limit block 13. The inner wall of the limit block 13 is provided with a hole and groove 14. The outer wall of the limit block 13 is rotatably connected to a clamping piece 15.

[0028] Reference Figures 1-5The height adjustment component includes a trapezoidal block 21. The outer wall of the trapezoidal block 21 is slidably connected to the inner wall of the base 1. A connecting rod 22 is fixedly connected to the inner wall of the trapezoidal block 21, which facilitates the application of external force to drive the trapezoidal block 21 to slide on the inner wall of the base 1. The inner wall of the base 1 has a first groove 16, a third groove 17, a fourth groove 18, and a second groove 23. A support rod 19 is fixedly connected to the lower surface of the chassis 2. The trapezoidal block 21 cooperates with the support rod 19 through its own inclined surface, and can lift or lower the support rod 19 during sliding, thereby realizing the height adjustment of the chassis 2 and the components above it. A locking plate 20 is slidably connected to the inner wall of the base 1. The locking plate 20 can be inserted into the corresponding third groove 17 to position the trapezoidal block 21 and prevent the trapezoidal block 21 from shifting after height adjustment. To ensure the height stability after adjustment, the outer wall of turntable 4 is rotatably connected to the inside of rotating groove 9. Rotating groove 9 is used to provide rotation guidance for turntable 4 while limiting its position. Steering rod 3 is rotatably connected to the inside of slot 1 7. Sliding rod 5 is slidably connected to the inner wall of clamping rod 6. Elastic claw head 8 is made of silicone material.

The outer wall of connecting rod 22 is slidably connected to the inner wall of slide groove 1 16. The outer wall of clamping plate 20 is slidably connected to the inner wall of slot 3 17. Clamping plate 20 is used to lock the position of trapezoidal block 21.

[0029] Working principle: When an elastic clamping centering device for turning metal blanks is needed, the screw 11 is rotated outward, causing the limiting block 13 to move away from the fixed block 10, which drives the turntable 4 to rotate. The sliding rod 5 rotates accordingly, causing it to slide away from the steering rod 3, which drives the clamping rod 6 to rotate in the slot 7, increasing the clamping diameter. The metal blank is placed in the center of the base plate 2. The above steps are reversed, and the clamping rod 6 rotates, decreasing the clamping diameter. The elastic claw 8 clamps the metal blank tightly, and the elastic claw 8 undergoes uniform deformation to determine the geometric center of the metal blank.

[0030] Furthermore, when it is necessary to adjust the height of the processed parts, push the connecting rod 22 to drive the trapezoidal block 21 to slide in the second slide groove 23. The inclined surface of the trapezoidal block 21 presses against the inclined surface of the support rod 19, causing the support rod 19 to slide upward in the fourth hole groove 18, driving the chassis 2 to move upward. After adjusting to the appropriate height, insert the clamping plate 20 into the third hole groove 17 that is close to the connecting rod 22 to lock the height of the chassis 2.
