DETAILED DESCRIPTION

[0023] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or reference letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0024] Currently, volutes on the market serve as the outer shells of equipment such as blowers, water pumps, and booster pumps. Most volutes are made of metal and are typically cast. A commercially available volute design comprises a housing 1, an air inlet 101, and an exhaust port 102. The housing 1 includes a flow passage connecting the air inlet 101 and the exhaust port 102. A mounting ring 103 is formed on the air inlet 101, and a flange 104 is formed on the housing 1. The flange 104 has four positioning holes 105, and one end surface of the flange 104 serves as a reference surface 106.

[0025] During the molding process, in order to ensure the size of the volute casing, it is often necessary to inspect multiple positions such as the volute casing's positioning holes. The inspectors measure them manually one by one. Due to the irregular shape of the volute casing and the lack of a positioning reference during measurement, the measurement speed is slow and easily leads to inaccurate measurement results.

[0026] In order to solve the above technical problems, the technical solution of this application provides a vortex casing position detection device. The technical solution is as follows:

[0027] The following is based on Figures 3 to 6 This application is described in further detail.

[0028] like Figure 3 As shown, the present application provides a vortex casing position detection device, including a bottom plate 2, the bottom plate 2 is horizontally arranged, and four supporting feet 201 are evenly distributed on the lower surface of the bottom plate 2. A supporting mechanism 3, an end positioning mechanism 4, and a detection mechanism 5 are also provided on the bottom plate 2.

[0029] like Figure 4 As shown, the support mechanism 3 includes a fixed seat 301 and a positioning member 302. The fixed seat 301 is connected to the upper surface of the base plate 2. The fixed seat 301 is used to support the volute, and the upper surface of the fixed seat 301 abuts the air inlet 101. The bottom of the fixed seat 301 is coaxially connected to a guide sleeve 303, which passes through the base plate 2.

[0030] like Figure 4 As shown, a positioning member 302 is slidably inserted into the fixing seat 301. The upper surface of the positioning member 302 is grooved and has an inclined first positioning surface 6, which is configured to abut the outer wall of the mounting ring 103. A guide rod 304 is coaxially connected to the bottom of the positioning member 302. The guide rod 304 passes through and slidably engages with the guide sleeve 303. The bottom end of the guide rod 304 extends out of the guide sleeve 303 and is threadedly connected to a horizontally arranged limit plate 305. The outer diameter of the limit plate 305 is larger than that of the guide sleeve 303.

[0031] like Figure 4As shown, the lower surface of the base plate 2 is connected to a driving cylinder 7, the piston end of which is vertically disposed and penetrates the base plate 2. A pull plate 701 is connected to the piston end of the driving cylinder 7. The pull plate 701 is horizontally disposed and positioned below the stop plate 305. A position sensor 306 is mounted on the fixing base 301. The position sensor 306 is configured to sense the position of the positioning member 302 and is electrically connected to the driving cylinder 7.

[0032] like Figure 4 As shown, a receiving groove 8 is formed on the inner bottom wall of the top groove of the fixing seat 301. The guide rod 304 passes through the receiving groove 8. An elastic component 9 is disposed within the receiving groove 8. The elastic component 9 comprises an elastic column 901 and a spring 902. The top end of the elastic column 901 abuts against the bottom of the positioning member 302, while the bottom end is inserted into the fixing seat 301. The spring 902 is sleeved on the elastic column 901 and squeezed between the bottom of the receiving groove 8 and the positioning member 302. In this embodiment, multiple elastic components 9 are provided around the guide rod 304.

[0033] Since the volute is heavy, when the volute is in hard contact with the fixed seat 301, the volute and the fixed seat 301 collide with each other and easily cause wear. While damaging the volute, the fixed seat 301 is also partially worn, thereby affecting the accuracy of the detection. Therefore, during the detection process, the volute is first placed on the positioning member 302, the elastic component 9 elastically deforms to cushion the placement of the volute, and then the piston end of the cylinder 7 is driven to move. The positioning member 302 carries the volute to move downward, and the position sensor 306 senses the position of the volute in real time. When the air inlet 101 of the volute abuts the fixed seat 301, the piston end of the driving cylinder 7 stops moving.

[0034] like Figure 5 As shown, the end positioning mechanism 4 includes a mounting base 401 and a pressing pin 402. The pressing pin 402 penetrates the mounting base 401 and is threadedly engaged with the mounting base 401. An end plate 403 is formed at the end of the pressing pin 402. Two guide pins 404 are fixedly connected to the end plate 403, and the guide pins 404 are provided with scales. The pressing pin 402 is located between the two guide pins 404. The guide pins 404 penetrate the mounting base 401 and are slidably engaged with the mounting base 401.

[0035] like Figure 5 As shown, during detection, the end plate 403 is inserted into the exhaust port 102, and an annular positioning groove 10 is opened on the peripheral wall of the end plate 403. The positioning groove 10 and the port of the exhaust port 102 are relatively arranged. The width of the positioning groove 10 is set according to actual conditions, and the inner wall of the positioning groove 10 is painted with color to mark it. While positioning, the position of the exhaust port 102 is simultaneously detected.

[0036] like Figure 3As shown, the detection mechanism 5 includes a measuring base 501, a detection pin 502, and a side wedge 503. The measuring base 501 is connected to the upper surface of the base plate 2. A fixing block 504 is fixedly connected to the measuring base 501. The side wedge 503 is plugged into and engaged with the fixing block 504 via a clamping bar 505. To ensure the stability of the side wedge 503, the clamping bar 505 is configured as a T-bar.

[0037] like Figure 3 As shown, the side wedge plate 503 is provided with a side positioning surface abutting the reference surface 106, and the side positioning surface is provided with a pressure membrane abutting the reference surface 106. When the volute rotates until the reference surface 106 abuts the pressure membrane, if the inspector continues to apply rotational force, when the pressure membrane tests that the pressure exceeds the threshold, the external industrial control equipment will alarm, further improving the stability of the volute position and avoiding excessive pressure on the rigid contact with the side wedge plate 503 due to excessive rotation of the volute.

[0038] like Figure 3 As shown, a detection pin 502 is slidably inserted into the measuring base 501, and the probe on the detection pin 502 is inserted into the corresponding positioning hole 105. In this embodiment, two detection pins 502 are provided. The base plate 2 is also provided with a clamping portion. When the reference surface 106 abuts the pressure membrane and the probe on the detection pin 502 is inserted into the corresponding positioning hole 105, the clamping portion presses against the flange portion 104.

[0039] like Figure 3 and Figure 6 As shown, the pressing portion includes a support base 12 and a telescopic rod 13. A rotating sleeve 14 is mounted on the telescopic rod 13. The rotating sleeve 14 is connected to a pressing head 16 via an adapter plate 15. The pressing head 16 can be rotated by rotating the sleeve 14, and the telescopic rod 13 is extended and retracted, so that the pressing head 16 presses against the flange portion 104, and the pressing point is located near the positioning hole 105.

[0040] like Figure 3 As shown, to enhance the compression effect on the volute, a mounting bracket 17 is connected to the base plate 2, to which an auxiliary compression member 18 is connected. In this embodiment, the auxiliary compression member 18 is a vertical quick clamp. To further expand the scope of application and detect the position of the volute, a fixing bracket 19 is connected to the base plate 2, and a number of gauges 20 are inserted into the fixing bracket 19.

[0041] The implementation principle of this application is as follows: During the inspection process, the volute is first placed on the positioning member 302. The elastic component 9 elastically deforms to cushion the placement of the volute. Then, the piston end of the cylinder 7 is driven to move. The positioning member 302 carries the volute downward. The sensor senses the position of the volute in real time. When the volute's air inlet 101 and the fixed seat 301 abut, the piston end of the driving cylinder 7 stops moving. The inspector rotates the volute until the reference surface 106 and the pressure membrane abut and ensures that the external equipment does not alarm. Then, the sliding inspection pin 502 is inserted into the positioning hole 105, and the inspector rotates the rotating sleeve 14. At the same time, the telescopic rod 13 is extended and retracted, so that the pressure head 16 is pressed against the flange portion 104. Next, the pressure pin 402 is rotated, and the pressure pin 402 links the end plate 403 so that the end plate 403 is inserted into the exhaust port 102. At the same time, the positioning groove 10 and the end of the exhaust port 102 are opposite, positioning the volute while testing whether the position of the exhaust port 102 is qualified. In summary, the volute can be quickly clamped and positioned, and a positioning basis is provided, which facilitates the measurement of the position of the volute and improves the accuracy of the measurement. In addition, the volute is elastically cushioned when placed, which reduces the possible damage to the volute during the measurement process.
