[0002] Special-shaped parts usually refer to workpieces with unconventional shapes or complex geometric features. They are materials or products that cannot be fixed using traditional fixtures. Therefore, a specially designed fixture is required to fix and position special-shaped parts for processing, assembly or inspection.

[0003] The special-shaped workpiece clamping fixture is customized and adjusted according to the specific shape and size of the special-shaped workpiece to ensure that the special-shaped workpiece can be completely fixed and positioned. However, when clamping the special-shaped workpiece, the existing fixture is often difficult to stably fix in the fixture due to its irregular shape, and it is difficult to control the clamping force, which may cause the special-shaped workpiece to be damaged or fall off. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special-shaped parts clamping fixture, comprising: a supporting cross plate, a lower tooth clamping block is fixedly connected to the middle part of the upper part of the supporting cross plate, a vertical rod is fixedly connected to one end of the upper part of the lower tooth clamping block, a spring is fixedly connected to the other end of the upper part of the lower tooth clamping block, one end of the spring is fixedly connected to an upper tooth clamping block, the other end of the upper part of the supporting cross plate is fixedly connected to a supporting frame, a fixing ring is fixedly connected to the middle part of the upper part of the supporting frame, a cylinder is fixedly connected to the inner side of the fixing ring, an inverted U-shaped pressure plate is fixedly connected to the movable end of the cylinder, a pressure block is fixedly connected to the lower end of the inverted U-shaped pressure plate, a stopper is fixedly connected to one end of the top of the vertical rod, and a handle rod is fixedly connected to the middle end of the upper tooth clamping block.

[0006] As a further solution of the utility model: one end of the side wall of the support frame is fixedly connected to an internal threaded tube, the internal thread of the internal threaded tube is threadedly connected to a threaded push rod, one end of the threaded push rod is fixedly connected to a handle, and the other end of the threaded push rod is fixedly connected to a push block.

[0007] As a further solution of the utility model: one upper end of the supporting horizontal plate 1 is fixedly connected to a supporting vertical plate, one upper end of the supporting vertical plate is fixedly connected to a supporting horizontal plate 2, and the other end of the cylinder is fixedly connected to the supporting horizontal plate 2.

[0008] As a further solution of the utility model: a limiting top groove is provided at the other end above the upper tooth clamping block, and the limiting top groove is adapted to the pressing block.

[0009] As a further solution of the utility model: a hemispherical groove is provided at the top end of the inner part of the inverted U-shaped pressure plate, and the hemispherical groove is adapted to the handle rod.

[0010] As a further solution of the utility model: the vertical rod passes through the upper tooth clamping block and is slidably connected with the upper tooth clamping block, and the spring is arranged outside the vertical rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The upper tooth clamp block is pulled up by the hand-held handle rod, and the workpiece is placed on the lower tooth clamp block. Through the action of the spring, the upper tooth clamp block rebounds downward along the vertical rod to clamp the special-shaped workpiece. In this way, the upper tooth clamp block and the lower tooth clamp block can clamp special-shaped parts of different sizes, and the workpiece can be fixed by the compression force of the spring, and damage to the workpiece caused by excessive clamping force can be avoided. Subsequently, the inverted U-shaped pressing plate is driven down by the cylinder to make the pressing block move downward and just get stuck in the limit top groove. At the same time, the top end of the handle rod is just inserted into the hemispherical groove, ensuring that the workpiece is firmly clamped, and it can be avoided that the workpiece is damaged during the processing. The elasticity of the spring may cause the clamped workpiece to loosen or fall off, resulting in the inability to process normally. The fixture has a stable structure and can adapt to special-shaped parts of different sizes. It provides sufficient clamping force through the cylinder to ensure that the special-shaped parts remain stable during processing or transportation; by holding the handle and turning the threaded push rod, the push block can be driven to push in the direction of the lower tooth clamp block, which can not only fine-tune the position of the special-shaped part, but also further consolidate the stability after being clamped; through the setting of the support horizontal plate 1, the support vertical plate and the support horizontal plate 2, the entire fixture can be placed upright or lying down to meet the needs of different directions or angles.
