Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to an adaptive clamping fixture for hardware and plastic products. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection; it is also called a clamp. Broadly speaking, any device used to quickly, conveniently, and safely install a workpiece in any step of the manufacturing process can be called a fixture. Fixtures are often used to clamp metal and plastic products during processing to facilitate machining and ensure accurate positioning. For example, patent (CN209615277U) describes a wear-resistant self-adaptive fixture for metal and plastic products. By manually rotating a wheel in the forward or reverse direction, a moving seat that engages with a positioning screw thread slides forward or backward along a push rail to accommodate metal and plastic products of different lengths. However, this requires frequent manual rotation of the wheel to adapt to different product lengths, resulting in a relatively complex operation. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adaptive clamp for hardware and plastic products.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design an adaptive clamp for hardware and plastic products, including a worktable. A pair of slide rods are vertically arranged on the upper surface of the worktable. The top of the pair of slide rods is fixedly connected to a fixed seat. The fixed seat is conical. A first plastic part is sleeved on the top of the fixed seat. A rotating claw is rotatably connected to the outer wall of the fixed seat. The bottom of the first plastic part abuts against the rotating claw. A second slide rod is slidably arranged in the inner cavity of the first slide rod. A suction cup is connected to the top of the second slide rod. An abutment block is connected to the bottom of the second slide rod. A first spring is sleeved on the outer wall of the second slide rod. The first spring is clamped between the first slide rod and the abutment block.

[0006] Preferably, a groove is formed on the upper surface of the workbench, and the first slide rod is slidably disposed in the groove.

[0007] Preferably, the outer walls of each pair of first slide rods are connected to connecting rods, and a second spring is connected between the pair of connecting rods.

[0008] Preferably, the bottom of the rotating claw is provided with a rotating shaft, the rotating shaft is rotatably connected to the fixed base, and the top of the rotating claw is bonded with an overlapping block, the overlapping block abutting against the inner wall of the first plastic part.

[0009] Preferably, the outer wall of the fixing seat is uniformly provided with slots, and a second plastic part is snapped between a pair of fixing seats, with the end of the second plastic part snapped into the slot.

[0010] Preferably, the fixing base is conical, and the plurality of rotating claws are circumferentially distributed at the bottom of the fixing base.

[0011] The self-adaptive clamp for hardware and plastic products proposed in this utility model has the following advantages: by setting a fixed base, rotating jaws and suction cups, the plastic part can be sleeved on the fixed base. Pressing the abutment block causes it to move upward, and when the abutment block moves upward, it drives the suction cup to move upward. At this time, the suction cup is attached to the bottom of the plastic part, and the plastic part moves down and abuts against the rotating jaws. At this time, the rotating jaws are pressed and rotate, so that the overlapping block abuts against the inner wall of the plastic part, thereby achieving the clamping and fixing of the plastic part. The whole clamping process is simple and easy to operate, and can adapt to the clamping and fixing of plastics of different diameters. Attached Figure Description
