High-precision detection device for numerical control equipment

The utility model discloses a high-precision detection device for numerical control equipment, which comprises a base, a transverse sliding groove is formed in the base, two first fixing structures are horizontally connected in the transverse sliding groove in a sliding manner, and a driving assembly for driving the two first fixing structures to be close to each other or far away from each other is mounted in the transverse sliding groove. Two vertical sliding grooves which are located in the front side and the rear side of the transverse sliding groove and communicate with the transverse sliding groove are formed in the base. The device is reasonable in structural design, a to-be-detected workpiece is stably fixed through the left side, the right side, the front side and the rear side, the shaking or displacement phenomenon of the to-be-detected workpiece in the detection process is avoided, the position of the to-be-detected workpiece is measured and positioned in cooperation with scale marks on the base,
