Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a cast iron processing clamp with a pressure detection function. Background Art

[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a clamp. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. Cast iron parts are objects cast with molten iron. The fixture can clamp the cast iron parts, stabilizing the cast iron parts while facilitating other processing of the cast iron parts.

[0003] The defects of a cast iron processing fixture with a pressure detection function in the prior art are: Patent document CN219504614U discloses that "the utility model belongs to the field of fixtures, and specifically provides a cast iron processing fixture with a pressure detection function. During installation, the gap can be used for snap-on installation, so that the cast iron processing fixture with a pressure detection function is not easy to loosen, and can be firmly placed on the workbench for clamping operations. The pressure between the cast iron part to be processed and the first limit block is sensed by the pressure sensing part, and the telescopic motor is controlled, so that the clamping plate clamps the cast iron part to be processed. The cast iron processing fixture with a pressure detection function can be adapted to cast iron parts to be processed of different sizes, and fast clamping can be achieved. At the same time, no manual operation is required for multiple clamping. The load-bearing block can effectively bear the weight of the clamping part and the cast iron part to be processed. The support block can further support the clamping part, thereby improving the load-bearing capacity of the cast iron processing fixture with a pressure detection function."

[0004] However, although the above device can clamp and weigh the cast iron parts when in use, it is unable to fix the small cast iron parts due to the limitations of the clamping plate and the telescopic device when in use. In addition, the cast iron parts sometimes have different shapes, and fixing them on one side alone is likely to cause the cast iron parts to slide upward during squeezing and fixation, making them unable to be fixed. At the same time, cast iron parts are generally heavy in size. When encountering large and heavy cast iron parts, the base of the device is easily damaged. Therefore, the device still has certain shortcomings and needs further improvement. Utility Model Content
