Description
Technical Field
[0001] The present application relates to the technical field of tooling and fixtures, and in particular to a tooling and fixture and a sample making machine for making non-metallic pipe inspection specimens. Background Art
[0002] Non-metallic pipes include various common plastic pipes (including rigid polyvinyl chloride pipes for water supply, ABS engineering plastic pipes, PP-R engineering plastic pipes, etc.), composite pipes (aluminum-plastic composite pipes, steel-plastic composite pipes, etc.), concrete pipes, rubber pipes, fiberglass pipes, etc. As an important non-metallic pipe, thermoplastic pipes have the advantage of corrosion resistance and are widely used in municipal water supply and gas pipelines. They are important pipes to replace steel pipes and iron pipes. They are also widely used in the field of oil and water medium transportation pipelines in oil fields as a matrix or lining. Among all kinds of thermoplastic pipes, polyethylene (PE) pipes are the most widely used. When non-metallic pipes are in use, the pipes will be affected by many factors such as temperature in the environment, mechanical loads, physical and chemical effects of the medium, etc. Therefore, the performance of the pipes is crucial to whether the pipes can be used for a long time.
[0003] In order to meet the use requirements, it is often necessary to test the various properties of non-metallic pipes. For pressure pipes, the most important performance parameter is mechanical performance. When conducting mechanical property testing, it is necessary to obtain dumbbell-shaped test specimens that meet the test requirements from the cut non-metallic pipe, and then conduct a tensile test. In the prior art, when making specimens required for mechanical property testing, it is usually necessary to first roughly process a section of the pipe cut into multiple blocks by manual cutting to obtain a primary specimen larger than the specimen size, and then finely process the obtained block primary specimens on processing equipment (such as an engraving machine) in turn to remove excess parts to obtain a specimen shape and size that meets the requirements of the tensile test. Especially when multiple specimens are to be obtained for a section of pipe, this method of obtaining test specimens has the problem of low processing efficiency.
[0004] An engraving machine is a mechanical device used for fine engraving or cutting on various materials. It usually uses computer numerical control (CNC) technology and can accurately perform three-dimensional engraving, relief, line engraving or plane cutting on the surface of the workpiece according to a pre-set design pattern or program. Its working principle is to achieve the desired engraving effect by using a tool or laser and other devices to perform precise movement and cutting on the surface of the workpiece under program control. When making test specimens required for the mechanical property test of non-metallic pipes, many companies will use engraving machines for fine processing to produce test specimens that meet the test requirements. However, when in use, the fixture of the engraving machine can usually only meet the clamping of relatively regular round or square workpieces. Therefore, there are certain shape restrictions on the block primary specimens obtained by rough processing on the pipe, and when using the engraving machine for fine processing of the specimen, it is necessary to frequently replace the block primary specimens to make multiple specimens, which leads to low processing efficiency.

[0021] Compared with the prior art, this application has the following beneficial effects:
[0022] 1. The jig for preparing non-metallic pipe test specimens provided by the present application can be used as a special jig for use on an engraving machine when preparing specimens required for mechanical property testing of non-metallic pipes. When in use, the entire jig of the present application can be installed on the work surface of the engraving machine through a fixed bracket. By arranging a pipe fixture on the fixed bracket, the non-metallic pipe intercepted from the sample source can be clamped and installed relatively stably by the pipe fixture, so as to cooperate with the engraving machine to efficiently realize the processing of the required specimens; since the present application is no longer limited to the way that the traditional engraving machine fixture can only clamp relatively regular round or square workpieces, it can directly clamp the non-metallic pipe, thus eliminating the process of rough processing into block-shaped primary specimens by manual cutting in the prior art, and the non-metallic pipe can be clamped once, and a plurality of test specimens can be processed on the non-metallic pipe in cooperation with the engraving machine, thereby improving the processing efficiency;

[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.
[0041] The present application provides a fixture for preparing non-metallic pipe test specimens, which can be used as a special fixture on an engraving machine when preparing specimens required for non-metallic pipe mechanical property testing. Figure 1-Figure 5 The fixture for making the non-metallic pipe sample includes a fixing bracket 100 with a front-to-back height difference and a pipe fixture 200 connected to the fixing bracket 100 .
[0042] Among them, Figure 1 and Figure 2 As shown, the fixed bracket 100 is a frame structure with a low front and a high rear. The pipe fixture 200 is arranged on the fixed bracket 100 in a manner of tilting forward and downward and can clamp the non-metallic pipe 300 required for processing the sample. The pipe fixture 200 consists of a first pipe fixture clamp 201 and a second pipe fixture clamp 202. The first pipe fixture clamp 201 and the second pipe fixture clamp 202 are arranged on the fixed bracket 100 with a left and right interval. The first pipe fixture clamp 201 is fixedly connected to one of the left and right sides of the fixed bracket 100, and the second pipe fixture clamp 202 is movably connected to the fixed bracket 100 and can move left and right relative to the first pipe fixture clamp 201.
[0043] The jig for making non-metallic tube samples provided in the embodiment of the present application can be installed on the work surface of the engraving machine through the fixed bracket 100 when the whole jig provided in the embodiment of the present application is used. By setting the pipe fixture 200 on the fixed bracket 100, the non-metallic tube 300 intercepted from the sample source can be clamped more stably by the pipe fixture 200, so as to cooperate with the engraving machine to efficiently realize the processing of the required sample. Since the present application is no longer limited to the way that the traditional engraving machine fixture can only clamp relatively regular round or square workpieces, the non-metallic tube 300 can be directly clamped by the set pipe fixture 200, thus eliminating the process of rough processing into block-shaped primary samples by manual cutting in the prior art, and the non-metallic tube 300 can be clamped once, and multiple test samples can be processed on the non-metallic tube 300 in cooperation with the engraving machine, avoiding the situation in the prior art that the engraving machine needs to frequently replace the block-shaped primary samples, thereby improving the processing efficiency.
[0044] The pipe clamp 200 in the embodiment of the present application is composed of a first pipe clamp 201 and a second pipe clamp 202. The non-metallic pipe 300 intercepted from the sample source is clamped by the first pipe clamp 201 and the second pipe clamp 202. Since the second pipe clamp 202 is movably connected to the fixed bracket and can move left and right relative to the first pipe clamp 201, the distance between the first pipe clamp 201 and the second pipe clamp 202 can be changed by moving the second pipe clamp 202, so that the non-metallic pipes 300 of different lengths within a certain length range can be clamped and installed, thereby facilitating sample processing.
[0045] The non-metallic tube 300 intercepted from the sample source is directly clamped by using the tooling fixture of the embodiment of the present application. When the sample is processed in conjunction with an engraving machine, the advantages of the computer numerical control (CNC) technology used in the prior art engraving machine can be fully utilized to directly process it into the required shape, avoiding the prior art method of first rough processing into a block and then fine processing. Therefore, the sample of the required shape can be directly fine-processed on the non-metallic tube 300, avoiding material waste.
[0046] The embodiment of the present application adopts a fixed bracket 100 with a frame structure that is low in front and high in the back, and the pipe fixture 200 is arranged on the fixed bracket 100 in a manner of being inclined forward and downward, thereby facilitating workers' operation when installing and disassembling the non-metallic pipe 300. In addition, the fixed bracket 100 with a frame structure not only saves manufacturing materials, but also facilitates the collection of waste chips generated when processing and testing samples, as well as the cleaning of the generated waste chips.
[0047] As an optional solution of the embodiment of the present application, Figure 1-Figure 3As shown, the fixed bracket 100 includes a support frame 101, a first connecting plate 102, a second connecting plate 103, an upper slide bar 104 and a lower slide bar 105; the fixed bracket 100 can install the first pipe clamp 201 and the second pipe clamp 202 in a forward and downward tilted manner. The first pipe clamp 201 and the second pipe clamp 202 are installed on the fixed bracket 100 in a forward and downward tilted manner. This method is not only convenient and beneficial for workers to install and disassemble the non-metallic pipe 300, but more importantly, when installed in the working position area of the engraving machine, it can cooperate with the engraving machine to expose the surface of the non-metallic pipe 300 to a greater extent, so as to facilitate the processing of the required test samples, and when the non-metallic pipe 300 is fixed once without adjusting the state of the non-metallic pipe, more test samples can be produced.
[0048] In this embodiment, the first connecting plate 102 and the second connecting plate 103 are symmetrically arranged on the left and right sides of the support frame 101. The first connecting plate 102 and the second connecting plate 103 are both vertically arranged and connected to the support frame 101. In actual applications, the first connecting plate 102 and the second connecting plate 103 can be made of steel plates, and the support frame 101 can be made of square tubes. The first connecting plate 102, the second connecting plate 103 and the support frame 101 can be welded into one.
[0049] The front end height of the first connecting plate 102 and the second connecting plate 103 is smaller than the rear end height. The first connecting plate 102 is provided with a first arc-shaped notch 1021 between the front and rear ends. The second connecting plate 103 is provided with a second arc-shaped notch 1031 corresponding to the first arc-shaped notch 1021 between the front and rear ends. The setting of the first arc-shaped notch 1021 and the second arc-shaped notch 1031 not only makes the overall shape of the fixing bracket 100 beautiful, but also can serve as a support for the temporary placement of the non-metallic pipe 300.
[0050] An upper slide bar 104 is fixedly connected between the high rear ends of the first connecting plate 102 and the second connecting plate 103, and a lower slide bar 105 is fixedly connected between the low front ends of the first connecting plate 102 and the second connecting plate 103, so that there is a height difference between the upper slide bar 104 and the lower slide bar 105, and the first pipe clamp 201 and the second pipe clamp 202 are commonly connected on the upper slide bar 104 and the lower slide bar 105, the first pipe clamp 201 is arranged on the inner side of the first connecting plate 102 and is fixedly connected to the first connecting plate 102, and the second pipe clamp 202 is located between the first pipe clamp 201 and the second connecting plate 103 and can move left and right between the two. The first pipe clamp 201 and the second pipe clamp 202 are both connected to the upper slide bar 104 and the lower slide bar 105 with a height difference, so that the first pipe clamp 201 and the second pipe clamp 202 are tilted forward and downward. Optionally, the upper sliding bar 104 and the lower sliding bar 105 are connected and installed with the first connecting plate 102 and the second connecting plate 103 in such a manner that the included angle between the vertical connecting line therebetween and the horizontal plane is 15°-35°.
[0051] In some embodiments of the present application, the first pipe clamp 201 and the second pipe clamp 202 are both openable clamps, and the first pipe clamp 201 and the second pipe clamp 202 can be opened to place and remove the non-metallic pipe 300.
[0052] The first pipe clamp 201 includes a first lower clamp 2011 and a first upper clamp 2012 located above the first lower clamp 2011 and detachably connected to the first lower clamp 2011; the two ends of the first lower clamp 2011 are respectively connected to the upper slide bar 104 and the lower slide bar 105, and the first connecting plate 102 is fixedly connected to the first lower clamp 2011. In this embodiment, the first upper clamp 2012 is detachably connected to the first lower clamp 2011, so that when cleaning the waste, the first upper clamp 2012 can be removed from the first lower clamp 2011, so that it is convenient to clean out the mixed waste. In addition, the first upper clamp 2012 is detachably connected to the first lower clamp 2011, so that it is convenient to place or remove the non-metallic pipe 300 after removing the first upper clamp 2012.
[0053] The second pipe clamp 202 includes a second lower clamp 2021 and a second upper clamp 2022 located above the second lower clamp 2021 and detachably connected to the second lower clamp 2021; the two ends of the second lower clamp 2021 are respectively connected to the upper slide bar 104 and the lower slide bar 105 and can move left and right. Similarly, in this embodiment, the second upper clamp 2022 is detachably connected to the second lower clamp 2021, so that when cleaning the waste, the second upper clamp 2022 can be removed from the second lower clamp 2021, so that it is convenient to clean out the mixed waste. Moreover, the second upper clamp 2022 is detachably connected to the second lower clamp 2021, so that it is convenient to place or remove the non-metallic pipe 300 after removing the second upper clamp 2022.
[0054] In some embodiments of the present application, the first lower clamping plate 2011 and the second lower clamping plate 2021 are arc-shaped clamping plates of the same size, the first upper clamping plate 2012 and the second upper clamping plate 2022 are arc-shaped clamping plates of the same size, and the first lower clamping plate 2011 is provided with a pin 600 at both ends above the position where the upper slide bar 104 and the lower slide bar 105 are connected, and the first lower clamping plate 2011 is connected to the first upper clamping plate 2012 upwardly through the pin 600. The first lower clamping plate 2011 is connected to the first upper clamping plate 2012 by the first bolt 20111, and is fixedly connected to the first upper clamping plate 2012 by the first fastening nut 20112. The second lower clamping plate 2021 is also provided with a pin 600 at both ends above the position where the upper slide bar 104 and the lower slide bar 105 are connected. The shaft 600 is connected with a second bolt 20211 that passes through the second upper clamping plate 2022 upward, and the second bolt 20211 is provided with a second fastening nut 20212. The second lower clamping plate 2021 passes through the second upper clamping plate 2022 upward through the second bolt 20211 and is fixedly connected to the second upper clamping plate 2022 through the second fastening nut 20212; when the first pipe clamping member 201 and the second pipe clamping member 202 clamp the non-metallic pipe 300, there are intervals between the two ends of the first lower clamping plate 2011 and the two ends of the first upper clamping plate 2012, respectively, and there are intervals between the two ends of the second lower clamping plate 2021 and the two ends of the second upper clamping plate 2022, respectively. Due to the existence of the interval, the clamping degree when clamping and fixing the non-metallic pipe can be appropriately adjusted. The existence of such a interval enables the clamped and fixed non-metallic pipe to be better clamped when the first fastening nut 20112 and the second fastening nut 20212 are screwed.
[0055] When in use, the first fastening nut 20112 on the first bolt 20111 and the second fastening nut 20212 on the second bolt 20211 can be loosened first, and then the non-metallic tube 300 to be processed and sampled can be placed in the first pipe clamp 201 and the second pipe clamp 202, and the position of the non-metallic tube 300 can be adjusted and the second pipe clamp 202 can be moved left and right to adjust the position. After adjustment, the first fastening nut 20112 and the second fastening nut 20212 can be tightened to stably clamp the two ends of the non-metallic tube 300 in the first pipe clamp 201 and the second pipe clamp 202. When it is necessary to remove the non-metallic tube 300 from which samples have been taken, the first fastening nut 20112 and the second fastening nut 20212 can be loosened again, so that the non-metallic tube 300 is no longer clamped by the first pipe clamp 201 and the second pipe clamp 202, so that the non-metallic tube 300 from which samples have been taken can be easily removed from the pipe clamp 200.
[0056] In some embodiments of the present application, both ends of the first lower clamp plate 2011 and both ends of the first upper clamp plate 2012 are respectively provided with extension grooves for allowing the first bolt 20111 to rotate outward, and the first bolt 20111 can rotate outward with the connected pin shaft 600 as the center and cause the first bolt 20111 to be separated from the first upper clamp plate 2012; both ends of the second lower clamp plate 2021 and both ends of the second upper clamp plate 2022 are respectively provided with extension grooves for allowing the second bolt 20211 to rotate outward, and the second bolt 20211 can rotate outward with the connected pin shaft 600 as the center and cause the second bolt 20211 to be separated from the second upper clamp plate 2022. In the present application, the extension groove is provided so that when the first fastening nut 20112 and the second fastening nut 20212 are loosened, the first bolt 20111 and the second bolt 20211 can be rotated toward one side of the extension groove, thereby enabling the first bolt 20111 to completely disengage from the first upper clamping plate 2012 and the second bolt 20211 to completely disengage from the second upper clamping plate 2022. In this way, the first upper clamping plate 2012 and the second upper clamping plate 2022 are no longer subject to locking constraints, thereby facilitating the removal of the first upper clamping plate 2012 and the second upper clamping plate 2022.
[0057] In some embodiments of the present application, a fixing member 1022 is provided on the first connecting plate 102, and the first connecting plate 102 is fixedly connected to the first pipe clamping member 201 through the fixing member 1022. In this embodiment, the first connecting plate 102 is connected to the first lower clamping plate 2011 through the fixing member 1022. Optionally, the fixing member 1022 is a positioning pin, and the first connecting plate 102 is connected to the first lower clamping plate 2011 by the positioning pin, so that the first lower clamping plate 2011 is further fixed while passing through the upper slide bar 104 and the lower slide bar 105.
