A disposable pneumatic turbine pair lock nose comprises a nose housing with a connecting handle at the rear end, wherein an air intake passage and an exhaust passage are formed in the connecting handle; the nose housing comprises an upper housing and a lower housing; the upper housing and the lower housing are connected, and a pneumatic turbine chamber is formed in the middle of the connecting part; a raised part is arranged at each of the front ends of the upper housing and the lower housing; a first fixing hole and a first fixing pillar are formed in the raised parts of the front ends of theupper housing and the lower housing respectively; the front ends of the upper housing and the lower housing are fixed by the first fixing hole and the first fixed pillar. The raised parts are arranged, so that the weight is increased and the stability of the nose is improved. The nose is simple in structure and convenient to produce, the air intake passage and the exhaust passage can be formed flexibly, the production is convenient, the drilling is avoided, the production cost is greatly reduced, the production rate of products is improved, the product vibration is greatly reduced and the operating stability is improved.
Description
technical field [0001] The invention relates to a disposable pneumatic turbine lock head. Background technique [0002] At present, the pneumatic turbine heads on the market all adopt the nose shell, and the upper end cover of the nose shell is provided with a loam cake structure. In the production process of the machine head shell, it is necessary to set up air intake channels, water vapor channels, and exhaust channels. The production process is complex and troublesome, and it cannot be supported by simple die-casting or injection molding. In the current production process, the air intake channel can only be set simply, and the corner for strengthening the air pressure cannot be set. In addition, during the working process of the machine head, due to the small weight of the running block and the uniform thickness of the wall surface of the machine head, it is easy to generate vibration.
