Description

Technical Field

[0001] This utility model relates to a dimension detection device, and more particularly to a dimension detection device for processing PE water supply pipes. Background Technology

[0002] In the production and processing of PE water supply pipes, the outer diameter, inner diameter, wall thickness, and length of the pipes are the core dimensional parameters that directly determine whether the product quality is up to standard. According to industry standards and production specifications, each finished pipe must undergo these parameter tests before it can proceed to subsequent warehousing, transportation, and installation. This testing process is a crucial preliminary step to ensure the safe and stable operation of PE water supply pipes in municipal water supply, building water supply and drainage, and other scenarios. However, the current industry standard for dimensional testing of PE water supply pipes generally adopts a "multi-tool independent measurement" mode, which involves using an outside micrometer to measure the outer diameter, an inside diameter gauge to measure the inner diameter, a wall thickness gauge to measure the wall thickness, and a measuring tape to measure the length. Workers need to frequently switch tools between different measurement processes, which not only lengthens the testing cycle for a single pipe but also increases the complexity of the operation process, making it difficult to adapt to the high efficiency requirements of modern assembly line production. During the frequent changes of measuring tools, workers need to adjust the placement of the PE water supply pipes multiple times, which can easily lead to inconsistent measurement benchmarks for different parameters due to pipe positioning deviations, resulting in significant measurement errors and affecting the accuracy of product quality assessment.

[0003] Therefore, it is necessary to design a dimensional inspection device for PE water supply pipe processing to solve the above-mentioned technical problems. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the technical problem to be solved is to provide a dimensional inspection device for processing PE water supply pipes.

[0005] A dimensional inspection device for processing PE water supply pipes includes a cross, a first scale, guide rods, a sliding rod, an outer diameter inspection component, an inner diameter inspection component, and a length inspection component. The first scale is horizontally arranged on the front sidewall of the cross. Square holes are opened on each cross bar of the cross, and guide rods are installed inside each of these square holes. A sliding rod is slidably arranged at the center of the cross. An outer diameter inspection component for measuring the outer diameter of the PE water supply pipe is installed between the front ends of the four guide rods and the sliding rods. An inner diameter inspection component for measuring the inner diameter of the PE water supply pipe is installed between the rear ends of the four guide rods and the sliding rods. A length inspection component for detecting the length of the PE water supply pipe is installed on the outer diameter inspection component.

[0006] As a preferred technical solution of this utility model, the outer diameter detection component includes an outer clamping tooth, a mounting sleeve, a first mounting seat, and a first buffer component. The four guide rods are slidably provided with outer clamping teeth at positions away from the axis of the sliding rod. The front end of each outer clamping tooth is rotatably provided with a mounting sleeve. The front end of the sliding rod is circumferentially spaced with four first mounting seats. The first buffer component is provided between the first mounting seat and the adjacent mounting sleeve.

[0007] As a preferred technical solution of this utility model, the inner diameter detection component includes an inner clamping tooth, a fixed plate, a second mounting seat, a third mounting seat, and a second buffer component. The four guide rods are slidably provided with inner clamping teeth near the axis of the sliding rod. A fixed plate is provided at the rear end of the sliding rod. Four second mounting seats are circumferentially spaced on the side wall of the fixed plate. The upper part of the inner side wall of the four inner clamping teeth is provided with a third mounting seat. A second buffer component is provided between the third mounting seat and the adjacent second mounting seat.

[0008] As a preferred technical solution of this utility model, the length detection component includes a measuring tape and a second scale. The outer side wall of the outer clamping teeth is provided with a mounting groove, the measuring tape is placed in the mounting groove of the outer clamping teeth, and the second scale is provided on the outer side wall of the outer clamping teeth.

[0009] As a preferred embodiment of this utility model, both the first buffer assembly and the second buffer assembly are composed of a movable column, a sleeve, and a first elastic element. The first mounting base of the first buffer assembly is rotatably provided with a sleeve, and the mounting sleeve is provided with a movable column. The movable column and the sleeve are slidably engaged, and the first elastic element is provided between the movable column and the sleeve. The second mounting base of the second buffer assembly is rotatably provided with a sleeve, and the third mounting base is rotatably provided with a movable column. The movable column and the sleeve are slidably engaged, and the first elastic element is provided between the movable column and the sleeve.

[0010] As a preferred technical solution of this utility model, it also includes a second elastic element, which is provided between the front end of the sliding rod and the front side wall of the cross.

[0011] This utility model has the following advantages:

[0012] 1. This device integrates outer diameter detection components, inner diameter detection components, and length detection components. Operators only need to insert the inner clamping teeth into the inside of the pipe and place the outer clamping teeth on the outside, then pull the sliding rod to simultaneously complete the detection of the outer diameter, inner diameter, and wall thickness. To measure the length, simply pull the measuring tape on the outer clamping teeth. This eliminates the need to switch tools and repeatedly adjust the pipe position, significantly shortening the inspection cycle for a single pipe and meeting the high efficiency requirements of modern production lines.

[0013] 2. When the sliding rod is pulled, the four outer locking teeth of this device adhere to the outer surface of the pipe, ensuring that the central axis of the sliding rod coincides with the central axis of the pipe. The inner locking teeth, under the action of the second buffer assembly, adhere to the inner ring sidewall of the pipe. Furthermore, the first and second buffer assemblies can buffer the pulling force through elastic elements, ensuring a tight fit between the inner and outer locking teeth and the pipe. Operators can accurately calculate relevant dimensions using the first scale, avoiding errors caused by inconsistent benchmarks, improving the accuracy of product quality assessment, and providing a more reliable guarantee for the safe and stable operation of PE water supply pipes in various scenarios.

Detailed Implementation

[0020] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0021] Example: Figures 1-5As shown, a dimensional inspection device for processing PE water supply pipes includes a crossbar 1, a first scale 2, guide rods 4, sliding rods 5, an outer diameter inspection component 6, an inner diameter inspection component 7, and a length inspection component 9. The first scale 2 is horizontally arranged on the front side wall of the crossbar 1. Square holes 3 are opened on each crossbar of the crossbar 1, and guide rods 4 are installed inside each square hole 3. A sliding rod 5 is slidably arranged at the center of the crossbar 1. A device for measuring the outer diameter of the PE water supply pipe is positioned between the front ends of the four guide rods 4 and the sliding rods 5. The outer diameter detection component 6 includes outer retaining teeth 61, mounting sleeves 62, first mounting seats 63, and first buffer components 64. The four guide rods 4 are slidably equipped with outer retaining teeth 61 at positions away from the axis of the sliding rod 5. The front ends of the outer retaining teeth 61 are rotatably equipped with mounting sleeves 62. Four first mounting seats 63 are circumferentially spaced at the front end of the sliding rod 5. The first buffer components 64 are positioned between the first mounting seats 63 and adjacent mounting sleeves 62. A buffer is provided between the four guide rods 4 and the rear ends of the sliding rod 5. An inner diameter detection assembly 7 for measuring the inner diameter of PE water supply pipes includes inner clamping teeth 71, a fixed plate 72, a second mounting base 73, a third mounting base 74, and a second buffer assembly 75. Inner clamping teeth 71 are slidably arranged on the four guide rods 4 near the axis of the sliding rod 5. A fixed plate 72 is located at the rear end of the sliding rod 5. Four second mounting bases 73 are circumferentially spaced on the side wall of the fixed plate 72. A third mounting base 74 is located on the upper inner side wall of each of the four inner clamping teeth 71. The third mounting base 74 is connected to the adjacent... A second buffer assembly 75 is provided between the second mounting bases 73. The outer diameter detection assembly 6 is provided with a length detection assembly 9 capable of detecting the length of the PE water supply pipe. The length detection assembly 9 includes a measuring tape 92 and a second scale 93. The outer side wall of the outer clamping teeth 61 is provided with a mounting groove 91. The measuring tape 92 is provided in the mounting groove 91 of the outer clamping teeth 61. The outer side wall of the outer clamping teeth 61 is provided with a second scale 93. It also includes a second elastic element 8. The second elastic element 8 is provided between the front end of the sliding rod 5 and the front side wall of the cross 1.

[0022] like Figure 3 As shown, both the first buffer assembly 64 and the second buffer assembly 75 consist of a movable post 10, a sleeve 11, and a first elastic element 12. The first mounting base 63 of the first buffer assembly 64 is rotatably fitted with the sleeve 11, and the mounting sleeve 62 is fitted with the movable post 10. The movable post 10 and the sleeve 11 are slidably engaged, and the first elastic element 12 is disposed between the movable post 10 and the sleeve 11. Similarly, the second mounting base 73 of the second buffer assembly 75 is rotatably fitted with the sleeve 11, and the third mounting base 74 is rotatably fitted with the movable post 10. The movable post 10 and the sleeve 11 are slidably engaged, and the first elastic element 12 is disposed between the movable post 10 and the sleeve 11.

[0023] When measurement is required, the operator inserts the inner locking tooth 71 of the device into the inside of the PE water supply pipe, with the outer locking tooth 61 located on the outside of the PE water supply pipe. Then, the sliding rod 5 is pulled forward, stretching the second elastic element 8. The sliding rod 5 drives the sleeve 11 of the first buffer assembly 64 to move forward. The moving column 10 drives the mounting sleeve 62 and the outer locking tooth 61 to move along the guide rod 4 towards the center of the cross 1. The outer locking tooth 61 then fits against the outer surface of the PE water supply pipe. Because the four outer locking teeth 61 are in contact, the central axis of the sliding rod 5 is kept aligned with the central axis of the PE water supply pipe. The forward movement of the sliding rod 5 pushes the inner locking tooth 71 away from the center of the cross 1 through the second buffer assembly 75. The inner locking teeth 71 are attached to the inner wall of the PE water supply pipe. During the pulling process, the moving column 10 and the sleeve 11 will slide relative to each other because the pulling force is difficult to control. The first elastic element 12 will deform accordingly, and finally the outer locking teeth 61 can be kept tightly attached to the side wall of the PE water supply pipe. The operator can quickly calculate the inner diameter of the PE water supply pipe, the outer diameter of the PE water supply pipe, and the wall thickness of the PE water supply pipe through the first scale 2. After the test is completed, the sliding rod 5 is released, and the second elastic element 8 drives the sliding rod 5 to reset. Then the outer diameter detection component 6 and the inner diameter detection component 7 also quickly reset, so that the device can be separated from the PE water supply pipe. The device has a simple structure and is easy to operate.

[0024] When measuring the inner diameter, outer diameter, and wall thickness of a PE water supply pipe, if it is also necessary to measure the length of the PE water supply pipe, simply pull the toothed belt of the measuring tape 92 until the hook on the toothed belt catches the edge of the other end of the PE water supply pipe. The length value can then be read directly. Then, read the distance from the second scale 93 to the initial end of the PE water supply pipe. Adding these two measurements together will determine the length of the PE water supply pipe.

[0025] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
