Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically a novel adjustable tooling and fixture. Background Technology

[0002] In fields such as machining, hardware manufacturing, automotive parts production, and precision instrument assembly, tooling fixtures serve as core auxiliary equipment for achieving precise workpiece positioning and stable clamping.

[0003] Existing fixtures often employ a single, fixed clamping structure. For example, rigid planar clamping blocks are designed only for flat workpieces, or curved slots are only suitable for cylindrical parts. This design means that a single fixture can only meet the clamping needs of a specific type of workpiece. When dealing with cylindrical workpieces, planar clamping blocks are prone to slippage, failing to achieve circumferential positioning. When dealing with polished precision parts or brittle plastic parts, the rigid clamping surface lacks a buffer structure, easily causing scratches and indentations on the workpiece surface. When dealing with hard workpieces such as high-strength alloys, conventional clamping surfaces have insufficient gripping force, and the workpiece is prone to loosening during machining due to cutting forces.

[0004] To cope with different workpieces, companies need to purchase multiple sets of special fixtures, which not only significantly increases equipment procurement costs and storage space, but also requires frequent disassembly and replacement of fixtures when switching workpieces, extending production preparation time and severely restricting production efficiency.

[0005] To address this, a novel adjustable tooling fixture is proposed. Summary of the Invention

[0006] The purpose of this utility model is to provide a novel adjustable tooling fixture to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a novel adjustable tooling fixture, comprising a base, wherein a movable frame is movably connected to one side of the upper surface of the base, and a fixed frame is fixedly connected to the other side; both the movable frame and the fixed frame are provided with clamping blocks inside, and the four sides of the clamping block are respectively a flat part, a groove part, a rubber part and a toothed part.

[0008] Both sides of the movable frame and the fixed frame are provided with placement slots, and the clamping block is equipped with limit rods at both ends, with the limit rods located inside the placement slots.

[0009] Preferably, a vertical plate is fixedly connected to one side of the upper surface of the base, and a threaded rod is threadedly connected to the vertical plate, the end of which is rotatably connected to one side of the movable frame.

[0010] Preferably, both sides of the movable frame and the fixed frame are rotatably connected to baffles that limit the position of the limiting rod.

[0011] Preferably, threaded holes are provided on both sides of the movable frame and the fixed frame, and a through hole is provided at one end of the baffle. A bolt is installed between the through hole and the threaded hole.

[0012] Preferably, the grooved portion has a triangular groove, the rubber portion has a rubber pad adhered to it, and the toothed portion has uniformly formed tooth grooves.

[0013] Preferably, the clamping block is a cuboid, and the clamping block is adapted to the internal space of the movable frame and the fixed frame.

[0014] Compared with existing technologies, the advantages of this utility model are: the four-sided functional clamping block can be adapted to various workpieces such as flat parts and cylindrical parts; one set of fixtures can replace multiple sets of special fixtures, significantly reducing equipment procurement and storage costs. The movable frame can be easily adjusted via threaded rods to adapt to workpieces of different sizes; the clamping blocks can be quickly switched and fixed with the help of limit rods and baffles, effectively shortening production preparation time and improving production efficiency.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figure 1-5This utility model provides a technical solution: a novel adjustable tooling fixture, including a base 1, a movable frame 2 movably connected to one side of the upper surface of the base 1, the movable frame 2 being able to move on the base 1 to adapt to the clamping requirements of workpieces of different sizes. A fixed frame 3 is fixedly connected to the other side of the upper surface of the base 1, the fixed frame 3 and the movable frame 2 cooperating with each other to achieve the clamping of the workpiece.

[0023] Both the movable frame 2 and the fixed frame 3 are equipped with clamping blocks 5 inside. The clamping blocks 5 directly contact the workpiece and clamp it. The four sides of the clamping blocks 5 are a flat part 51, a groove part 52, a rubber part 53 and a toothed part 54, which can be adapted to workpieces of different shapes and materials, improving the versatility of the fixture and the clamping effect.

[0024] Both sides of the movable frame 2 and the fixed frame 3 are provided with placement slots 8. Limiting rods 9 are installed at both ends of the clamping block 5. The limiting rods 9 are located inside the placement slots 8. The placement slots 8 provide placement space for the limiting rods 9. The limiting rods 9 cooperate with the placement slots 8 to limit the position of the clamping block 5 in the movable frame 2 and the fixed frame 3, prevent the clamping block 5 from shifting during the clamping process, and ensure the stability and accuracy of the clamping.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown: A vertical plate 10 is fixedly connected to one side of the upper surface of the base 1. A threaded rod 6 is threadedly connected to the vertical plate 10. The threaded rod 6 engages with the vertical plate 10 through threads, and its axial movement is achieved by rotating the threaded rod 6. The end of the threaded rod 6 is rotatably connected to one side of the movable frame 2. When the threaded rod 6 moves axially, it can push or pull the movable frame 2 on the base 1, thereby adjusting the distance between the movable frame 2 and the fixed frame 3 to meet the clamping requirements of workpieces of different sizes. The operation is convenient and the adjustment accuracy is high.

[0026] like Figure 2 and Figure 3 As shown: Both sides of the movable frame 2 and the fixed frame 3 are rotatably connected to baffles 4 that limit the position of the limiting rod 9. Both sides of the movable frame 2 and the fixed frame 3 are provided with threaded holes 7. One end of the baffle 4 is provided with a through hole 41. A bolt is installed between the through hole 41 and the threaded hole 7. The baffle 4 can rotate around its connection point with the movable frame 2 and the fixed frame 3. After the clamping block 5 is placed inside the movable frame 2 and the fixed frame 3, the baffle 4 is rotated to align the through hole 41 with the threaded hole 7. Then, the position of the baffle 4 is fixed by bolts, thereby completing the fixing of the position of the clamping block 5.

[0027] like Figure 4 and Figure 5As shown: The groove portion 52 has a triangular groove, which clamps and secures cylindrical workpieces, preventing slippage during processing. The rubber portion 53 has a rubber pad adhered to it. This rubber pad has good elasticity and friction, protecting the workpiece surface from damage caused by excessive clamping force. It also increases friction with the workpiece, improving clamping effectiveness, making it particularly suitable for workpieces with fragile or smooth surfaces. The toothed portion 54 has evenly spaced tooth grooves, which enhance the clamping force with the workpiece. This is suitable for clamping hard materials requiring greater clamping force, ensuring the workpiece does not loosen during processing.

[0028] like Figure 4 and Figure 5 As shown, the clamping block 5 is a cuboid. This cuboid structure gives it a regular shape, facilitating installation, adjustment, and replacement within the movable frame 2 and the fixed frame 3. The clamping block 5 is adapted to the internal space of the movable frame 2 and the fixed frame 3, meaning it can fit tightly against them, preventing gaps that could cause it to wobble. This ensures the stability and reliability of the clamping block 5 when clamping the workpiece, and also ensures that the clamping force is evenly transmitted to the workpiece.

[0029] Working principle: First, select the corresponding working surface of clamping block 5 according to the shape and material of the workpiece to be processed. When processing regular planar workpieces, select the planar part 51. When processing cylindrical workpieces, select the grooved part 52 with triangular grooves. When processing workpieces with fragile or smooth surfaces, select the rubber part 53 with adhesive rubber pads. When processing hard workpieces that require strong clamping force, select the toothed part 54 with toothed grooves.

[0030] Then, the clamping block 5 is placed inside the movable frame 2 and the fixed frame 3, ensuring that the limiting rods 9 at both ends of the clamping block 5 are accurately embedded in the placement grooves 8. Through the cooperation between the limiting rods 9 and the placement grooves 8, the offset of the clamping block 5 inside the frame is limited. Rotate the baffle 4 so that the through hole 41 at one end of the baffle 4 is aligned with the threaded hole 7 on the frame. Then, insert bolts into the mating part of the through hole 41 and the threaded hole 7 and tighten them. The baffle 4 limits the limiting rods 9, thereby stably fixing the clamping block 5 inside the movable frame 2 and the fixed frame 3, preventing the clamping block 5 from loosening during processing.

[0031] Place the workpiece to be processed on the base 1, between the movable frame 2 and the fixed frame 3. Then rotate the threaded rod 6 on the vertical plate 10 fixedly connected to one side of the upper surface of the base 1. Since the end of the threaded rod 6 is rotatably connected to one side of the movable frame 2, the threaded rod 6 will move axially when it rotates, thereby pushing the movable frame 2 to slide along the base 1 towards the fixed frame 3, until the clamping blocks 5 inside the movable frame 2 and the fixed frame 3 are in close contact with the surface of the workpiece, realizing the stable clamping of the workpiece. At this time, the workpiece processing operation can be carried out.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
