Description

Technical Field

[0001] This utility model belongs to the field of four-way detection technology, and specifically relates to a square four-way detection device. Background Technology

[0002] Square four-way connectors are key connecting components in piping systems used to achieve fluid diversion and merging, and are widely used in water conservancy, chemical industry, construction and other fields. Their structure typically includes one main channel and three branch channels (or four symmetrical channels). Parameters such as the perpendicularity of the channel axis, symmetry, and wall thickness uniformity directly affect the sealing performance and service life of the piping system; therefore, strict testing is required during the manufacturing process.

[0003] Currently, the inspection of square four-way connectors mostly relies on manual operation or simple inspection equipment, which has the following technical problems: low inspection efficiency: traditional inspection often uses a single set of inspection tools (such as dial indicators and calipers) to measure the parameters of each of the four channels one by one. A single inspection requires changing the inspection position multiple times, and the operation process is cumbersome. Especially in mass production scenarios, the inspection efficiency is difficult to meet production needs. Utility Model Content

[0004] This utility model addresses the problems of existing technologies by providing a square four-way detection device, the specific technical solution of which is as follows: A square four-way detection device includes: The testing table has a workpiece placement area at the center and a testing area surrounding the workpiece placement area on its end face. An annular channel is opened in the testing area, and a rotating ring is rotatably arranged inside the annular channel. It also includes four sets of detection components, all of which are mounted on a rotating ring and evenly distributed around the circumference. The rotating ring is driven by an external force to make the four sets of detection components rotate synchronously around the workpiece.

[0005] As a further technical solution of this utility model, the detection component includes a support column, a support plane, and a detection element, wherein the detection element is installed on the support plane and the output direction is towards the workpiece placement area, and the support column is connected to the bottom of the support plane to give the detection element a certain height.

[0006] As a further technical solution of this utility model, the outer peripheral wall of the rotating ring is provided with toothed grooves; A fixing component is provided on the detection area. The fixing component includes a chamber, a rod, and a spring. The chamber is opened in the detection area of ​​the detection table. The head of the rod passes through the chamber and is inserted into the rotating ring to engage with the tooth groove. The tail of the rod extends outside the detection table.

[0007] As a further technical solution of this utility model, the spring is pre-compressed and connected between the chamber and the insertion rod to drive the insertion rod to press against the tooth groove.

[0008] As a further technical solution of this utility model, the head of the insertion rod has a tooth tip that matches the tooth groove, and the tooth tip is normally inserted into the tooth groove to restrict the rotation of the detection area. As a further technical solution of this utility model, the insertion rod is externally connected to an extension plate. When the insertion rod is pulled, the extension plate is placed in the cavity and compresses the spring to further compress it.

[0009] The beneficial effects of this utility model are as follows: (1) Combining synchronous detection with efficiency improvement; Traditional square four-way inspection methods typically employ a single set of inspection components to inspect each of the four channels individually, resulting in a cumbersome and time-consuming inspection process. This solution, however, utilizes four sets of circumferentially distributed inspection components to simultaneously inspect all four channels of the workpiece, significantly shortening the inspection cycle, greatly improving inspection efficiency, and overcoming the limitations of traditional "one-by-one inspection."

[0010] (2) Flexible design for adaptive angle adjustment; When placing square four-way workpieces, it is difficult to ensure that the angles are completely consistent. Traditional detection devices require repeated manual adjustments to the position of the workpiece or detection components, which is complex and prone to errors. This solution uses a rotatable ring structure, allowing the four detection components to rotate synchronously around the workpiece, actively adapting to different placement angles of the workpiece. This eliminates the need to reposition the workpiece, simplifies the operation process, and improves adaptability to diverse workpiece placements.

[0011] (3) A synergistic mechanism of stable locking and convenient adjustment; Traditional detection devices often employ rigid locking mechanisms, which are either difficult to adjust or lack stability after adjustment, affecting detection accuracy. This solution's fixing component uses a pre-compressed spring to drive a rod that engages with the rotating ring's toothed groove. Under normal conditions, this locks the rotating ring stably (ensuring steady-state operation during detection). Pulling the rod releases the lock (facilitating adjustment of the detection component's position). Furthermore, the matching of the tooth tip and groove, along with the extension plate's limitation on the spring, balances locking reliability with ease of adjustment, resolving the technical contradiction of "difficulty in balancing stability and flexibility."

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0015] Figure 1 A schematic diagram of the overall structure of the square four-way detection device is shown; Figure 2 A schematic diagram of the detection component 200 is shown; Figure 3 A structural schematic diagram of the fixing component 300 is shown.

[0016] Figure 1 The square four-way inspection device includes an inspection platform 100 and four sets of inspection components 200. The end face of the inspection platform 100 has a workpiece placement area 110 at its center and an inspection area 120 surrounding the workpiece placement area 110. The four sets of inspection components 200 are all disposed on the inspection area 120 and evenly distributed circumferentially. In actual use, the workpiece is placed in the workpiece placement area 110 on the inspection platform 100, and the four inspection components 200 can simultaneously inspect the four channels of the workpiece, significantly improving inspection efficiency. An annular channel 121 is provided at the measurement area 120. A rotating ring 122 is rotatably arranged inside the annular channel 121. Four sets of detection components 200 are all installed on the rotating ring 122. The rotating ring 122 can be driven by an external force to drive the four sets of detection components 200 to rotate synchronously around the workpiece. After the workpiece is placed on the workpiece placement area 110, the position of its channel and the position of the detection components 200 often do not correspond. At this time, driving the rotating ring 122 to rotate can drive the detection components 200 to rotate synchronously to actively detect the channel position, thereby adapting to the diversity of workpiece placement angles.

[0017] Figure 2In this process, the detection component 200 includes a support column 210, a support plane 220, and a detection element 230. The detection element 230 is mounted on the support plane 220 with its output direction facing the workpiece placement area 110. The support column 210 is connected to the bottom of the support plane 220 to give the detection element 230 a certain height. The detection is achieved by using the support column 210 and the support plane 220 to make the height of the detection element 230 correspond to the height of the channel. It should be noted that the detection element 230 is not specifically limited and can be selected according to the actual situation. For example, the detection element 230 is a probe that contacts the workpiece surface to collect three-dimensional coordinate points and calculate the perpendicularity of the axis. Another example is that the detection element 230 is a camera-type vision inspection system that extracts the outline of the four-way through edge detection and calculates the symmetry. Yet another example is that the detection element 230 is a laser scanner that performs non-contact scanning to generate point cloud data and detect the wall thickness uniformity of the cast four-way.

[0018] Figure 1 Combination Figure 3 The outer peripheral wall of the rotating ring 122 is provided with toothed grooves 123. The fixing assembly 300 includes a chamber 310, a rod 320, and a spring 330. The chamber 310 is located in the detection area 120 of the detection table 100. The head of the rod 320 passes through the chamber 310 and is inserted into the rotating ring 122 to engage with the toothed grooves 123. The tail of the rod 320 extends outside the detection table 100. Controlling the tail of the rod 320 can drive the head of the rod 320 to insert into or disengage from the rotating ring 122, thereby changing the state of the head of the rod 320 and the toothed grooves 123. When the head of the rod 320 presses against the toothed grooves 123, it can restrict the overall rotation of the detection area 120 to ensure a steady state during the detection process. When the head of the rod 320 disengages from the rotating ring 122, the restriction of the toothed grooves 123 is released, allowing rotation, which is beneficial for adjusting the position of the detection assembly 200. The spring 330 is pre-compressed. Between the chamber 310 and the insertion rod 320, the insertion rod 320 is driven to press against the tooth groove 123; that is, under normal conditions, the insertion rod 320 is driven by the spring 330 and engages with the tooth groove 123 to restrict the rotation of the detection area 120, and the restriction is only released when the insertion rod 320 is pulled by an external force; the head of the insertion rod 320 has a tooth tip 321 that matches the tooth groove 123, and the tooth tip 321 is inserted into the tooth groove 123 under normal conditions to restrict the rotation of the detection area 120; the engagement of the tooth tip 321 with the tooth groove 123 further enhances the locking effect; an extension plate 322 is connected to the outside of the insertion rod 320, and when the insertion rod 320 is pulled, the extension plate 322 is placed in the chamber 310 and squeezes the spring 330 to further compress it; the engagement of the extension plate 322 with the spring 330 restricts the movement range of the insertion rod 320 and prevents the insertion rod 320 from completely detaching from the detection stage 100. The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
