AI Technical Summary
The prior art cannot quickly and accurately detect whether the three eccentric arcs on the turbine shell have been processed, resulting in a high risk of missing processing. It takes a long time to use a three-axis coordinate measuring machine to detect, which increases the detection cost and reduces production efficiency.
An anti-stupid detection device for eccentric arc of the turbine shell is designed, including an anti-error positioning core, a proximity sensor and an anti-error pin shaft. By cooperating with the central hole of the finished turbine shell, the proximity sensor and the anti-pin shaft are used to achieve rapid detection of three eccentric arcs.
The rapid detection of three eccentric arcs of the turbine shell is achieved, which improves the detection speed and accuracy, reduces the detection cost, and avoids the problem of missing processing.

Abstract
Description
Technical Field
[0001] The utility model relates to a turbine shell detection device, and specifically discloses a fool-proof detection device for an eccentric circular arc of a turbine shell. Background Art
[0002] The turbine housing has three eccentric arcs processed on the edge of the center hole. Since the three eccentric arcs and the center hole cannot be processed in one sequence and the processing amount of the three eccentric arcs is very small, the maximum eccentricity between the axis of the three eccentric arcs and the axis of the T hole is only 0.05mm, which makes it difficult to find out with the naked eye whether the three eccentric arcs have been processed, and it is very easy to miss the processing of the three eccentric arcs.
[0003] Currently, there is no special inspection tool for inspecting the three eccentric arcs on the turbine shell, and it is impossible to timely inspect whether the three eccentric arcs on the turbine shell have been processed. If the three eccentric arcs on the turbine shell are not processed, the operator cannot quickly and accurately find the problematic workpiece.
[0004] If the three eccentric arcs on each turbine housing are inspected using a CMM (i.e., a three-axis coordinate measuring machine), the inspection will take a long time and be slow, which will increase the inspection cost and reduce production efficiency. Summary of the invention
[0005] The utility model aims to overcome the shortcomings of the prior art and provide a fool-proof detection device for an eccentric arc of a turbine shell with fast detection speed, high accuracy and low detection cost.
[0006] According to the technical solution provided by the utility model, the anti-mistake detection device for the eccentric arc of the turbine shell includes an anti-mistake positioning core, a proximity sensor and an anti-mistake pin shaft; the anti-mistake positioning core cooperates with the center hole of the finished turbine shell, and a proximity sensor mounting hole and an anti-mistake pin shaft mounting hole are opened in the anti-mistake positioning core, the anti-mistake pin shaft mounting hole is located directly above the proximity sensor mounting hole, the upper end of the proximity sensor mounting hole is an open end, and the lower section of the proximity sensor mounting hole is a blind end, a proximity sensor is installed in the proximity sensor mounting hole, the anti-mistake pin shaft can be raised and lowered relative to the proximity sensor, and part of the side shape of the anti-mistake pin shaft is consistent with the side shape of the center hole at the three eccentric arcs on the finished turbine shell, and the side shape of the anti-mistake pin shaft is consistent with the side shape of the anti-mistake pin shaft mounting hole.
[0007] Preferably, an anti-slip cover is fixed to the upper end of the anti-misalignment pin shaft.
[0008] After the utility model is used, the detection speed of the three eccentric arcs on the turbine shell can be accelerated, the detection accuracy is high and the detection cost is low. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1It is the front view of the utility model.
[0010] Figure 2 yes Figure 1 AA section view. DETAILED DESCRIPTION
[0011] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0012] A foolproof detection device for an eccentric arc of a turbine housing, such as Figure 1 and Figure 2 As shown, it includes an anti-error positioning core 1, a proximity sensor 2 and an anti-error pin 3; the anti-error positioning core 1 cooperates with the center hole of the finished turbine shell, and a proximity sensor mounting hole 1.1 and an anti-error pin mounting hole 1.2 are opened in the anti-error positioning core 1, the anti-error pin mounting hole 1.2 is located directly above the proximity sensor mounting hole 1.1, the upper end of the proximity sensor mounting hole 1.1 is an open end, and the lower section of the proximity sensor mounting hole 1.1 is a blind end, and a proximity sensor 2 is installed in the proximity sensor mounting hole 1.1, and the anti-error pin 3 can be raised and lowered relative to the proximity sensor 2, and part of the side shape of the anti-error pin 3 is consistent with the side shape of the center hole at the three eccentric arcs on the finished turbine shell, and the side shape of the anti-error pin 3 is consistent with the side shape of the anti-error pin mounting hole 1.2.
[0013] An anti-slip cover 4 is fixed to the upper end of the anti-misalignment pin shaft 3 .
[0014] When the utility model is in use, the anti-mistake positioning core 1 is first fixed on the upper surface of the base plate so that the axis of the anti-mistake positioning core 1 is perpendicular to the upper surface of the base plate, and the open end of the proximity sensor mounting hole 1.1 is vertically facing upward, and then the proximity sensor 2 is installed in the proximity sensor mounting hole 1.1, and then the turbine shell 5 to be detected is installed on the anti-mistake positioning core 1 through its center hole, and then the anti-mistake pin shaft 3 is clamped by a mechanical arm or a worker's hand and moved toward the anti-mistake pin shaft mounting hole 1.2. If the anti-mistake pin shaft 3 can be normally inserted into the anti-mistake pin shaft mounting hole 1.2, the proximity sensor 2 generates an electrical signal, indicating that the three eccentric arcs on the turbine shell 5 to be detected have been processed; if the anti-mistake pin shaft 3 cannot be inserted into the anti-mistake pin shaft mounting hole 1.2, the proximity sensor 2 cannot generate an electrical signal, which indicates that the three eccentric arcs on the turbine shell 5 to be detected have not been processed and need to be reworked.
[0015] The anti-slip cover 4 fixed on the upper end of the anti-error pin shaft 3 can prevent the anti-error pin shaft 3 from slipping when the robot arm or the worker clamps the anti-error pin shaft 3 with their hands, so that the robot arm or the worker can clamp the anti-slip cover 4 with their hands to drive the anti-error pin shaft 3 to move toward the anti-error pin shaft mounting hole 1.2 for detection.
[0016] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
