Description
Technical Field
The utility model relates to a sand blasting machine especially relates to a special sandblast nozzle of turbine shell runner.
Background
A quality that is used for turbo charger's turbine shell to clear up the oxide layer of its inside and outside surface after the casting, because the position of turbine shell runner is darker, current general sandblast nozzle can't go deep into the turbine shell runner in with the oxide layer clean up, is difficult to guarantee the turbine shell increases the defective rate of turbine shell.
SUMMERY OF THE UTILITY MODEL
The applicant carries out research and improvement aiming at the problems and provides the special sand blasting nozzle for the turbine shell runner, which has the advantages of simple and compact structure, low manufacturing cost, convenience in operation, capability of extending into the turbine shell runner to clean the surface oxide layer, improvement on the product qualification rate and guarantee on the product quality, and is used for cleaning the surface oxide layer of the turbine shell runner.
In order to solve the technical problem, the utility model discloses a following technical scheme:
a special sand blasting nozzle for a turbine shell flow passage comprises a connecting sleeve, a nozzle body and a lengthened spray pipe, wherein the connecting sleeve is cylindrical, one end of the connecting sleeve is connected with a leather hose of a sand blasting machine, and the other end of the connecting sleeve is provided with an internal thread; a conical hole is formed in the nozzle body, a discharge hole is formed at the small end of the conical hole, a feed inlet is formed at the large end of the conical hole, a connecting section is arranged at the feed inlet end of the nozzle body and provided with external threads, and the nozzle body is connected with the internal threads of the connecting sleeve through the connecting section; a counter bore is formed in the discharge port end of the nozzle body, and internal threads are formed in the counter bore; the nozzle comprises a nozzle body, a lengthened spray pipe and a discharge hole, wherein the lengthened spray pipe is a long and thin circular pipe, the inner side end of the lengthened spray pipe is in threaded connection with a counter bore of the nozzle body, and the diameter of an inner bore of the lengthened spray pipe is the same as the inner diameter of the discharge hole of the nozzle body.
Further:
the length-diameter ratio of the length of the lengthened spray pipe to the inner diameter of the inner hole is more than 30.
The technical effects of the utility model lie in:
the utility model discloses a special sandblast nozzle of turbine shell runner, simple structure is compact, low in manufacturing cost for the clearance of turbine shell runner surface oxide layer, convenient operation can stretch into turbine shell runner clearance surface oxide layer, improves the product percent of pass, ensures product quality.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic diagram of the three-dimensional structure of the present invention.
Detailed Description
The following describes the embodiments of the present invention in further detail with reference to the attached drawings.
As shown in fig. 1 and 2, the utility model discloses a nipple 1, nozzle body 2 and extension spray tube 3, nipple 1 are cylindricly, and the leather hose 4 of sand blasting machine is connected to the one end of nipple 1, and the other end is equipped with the internal thread. Be equipped with conical bore 21 in the nozzle body 2, the tip of conical bore 21 forms discharge gate 23, and the major ingredient of conical bore 21 forms the feed inlet, and the feed inlet end of nozzle body 2 is equipped with linkage segment 22, and linkage segment 22 is equipped with the external screw thread, and nozzle body 2 passes through the internal thread that linkage segment 22 connects nipple 1. The discharge gate end of nozzle body 2 is equipped with the counter bore, and the counter bore is equipped with the internal thread, and extension spray tube 3 is long and thin pipe, and the medial extremity threaded connection nozzle body's of extension spray tube 3 counter bore, and the bore diameter of extension spray tube 3 is the same with the internal diameter of nozzle body's 2 discharge gate, can avoid causing spray pressure's change because of the internal diameter change like this, ensures the effect of sand blasting treatment. The length of the elongated lance 3 can be determined according to actual needs, and in the embodiment, the length-diameter ratio of the elongated lance 3 to the inner diameter of the inner bore is greater than 30.
When in actual use, the lengthened spray pipe 3 is connected with the nozzle body 2 and is assembled with a leather hose of sand blasting equipment through the connecting sleeve 1, and then a machine is started to perform local sand blasting on a workpiece. Because the lengthened spray pipe 3 of the spray head is thinner and longer, the lengthened spray pipe can extend into a deeper position of the turbine shell flow passage to carry out local sand blasting treatment, thereby ensuring the sand blasting quality of the whole turbine shell flow passage, improving the product percent of pass, reducing the rejection rate of blanks, ensuring the product quality and reducing the production cost.
