Description

Technical Field

[0001] This invention relates to the field of plastic pipe testing equipment technology, and specifically to a tooling for quality testing of plastic drain pipes. Background Technology

[0002] In production and daily life, plastic pipes are favored by the plastic pipe engineering industry due to their light weight, low water flow resistance, and green safety. Plastic drainage pipes are widely used in the plastic pipe manufacturing industry. After the plastic pipes are produced, they need to be subjected to bending and compressive strength tests in order to predict the denting and deformation caused by hard objects pressing into the batch of plastic pipes.

[0003] Chinese utility model patent CN214472440U, entitled "A Tooling for Testing the Bending Strength of Plastic Pipes," describes a device that, during bending operations, involves the worker first placing the plastic pipe onto a mounting sleeve along a first guide slope. Then, a force-applying rod is inserted along a second guide slope into the end of the plastic pipe axially away from the mounting sleeve. Next, the worker holds a rubber handle and pulls it downwards, causing the plastic pipe to bend axially towards the end of the handle, resulting in plastic deformation until it breaks. This completes the bending strength test of the plastic pipe, effectively improving the convenience of bending strength testing and saving manpower.

[0004] The above-mentioned device has some shortcomings. It is not convenient to perform pressure resistance and bending tests at the same time. The test process is simple and affects the test efficiency. Therefore, a quality inspection tool for plastic drain pipes that can solve the above problems is proposed. Summary of the Invention

Gear 414, and an arc-shaped through hole 41 is provided at the position corresponding to the first bevel gear 413 on the testing table 1. A sliding column 415 is slidably installed in the arc-shaped through hole 41. The sliding column 415 slides in the arc-shaped through hole 41 to facilitate bending operations. The mounting frame 416 is fixedly installed on the sliding column 415. The drain pipe is installed on the mounting frame 416. The end of the sliding column 415 away from the mounting frame 416 is fixedly installed on the first bevel gear 413. A motor 42 is fixedly installed on the testing table 1. A fixing unit and an elastic component 6 are provided on the mounting frame 416.

[0032] The pressure unit includes a pressing plate 48. Two stabilizing plates 46 and a toothed plate 47 are slidably mounted on the mounting frame 2.

The pressing plate 48 is used to press the plastic drain pipe on the gasket 10 for pressure resistance testing. A pressure sensor 49 is fixedly mounted on the side of the pressing plate 48 away from the toothed plate 47. The pressure sensor 49 is a device or apparatus that can sense pressure signals and convert the pressure signals into usable output electrical signals according to a certain rule. When the pressure sensor 49 detects pressure, it transmits the signal to the pressure display instrument 45. A drive rod 412 is rotatably mounted on the mounting frame 2. A drive gear 410 is fixedly mounted on the drive rod 412. The drive rod 412 drives the drive gear 410 to rotate. The drive gear 410 drives the toothed plate 47 to slide on the mounting frame 2. The pressure display instrument 45 is fixedly mounted on the side of the mounting frame 2 away from the test table 1. A linkage unit is provided between the bending unit and the pressure unit.

[0033] The linkage unit includes a belt 43, a first bevel gear 413 and a second bevel gear 414 meshing with each other to facilitate the sliding of the slide column 415 within the arc-shaped through hole 41 for bending testing.

The second bevel gear 414 rotates, simultaneously engaging the first bevel gear 413 and causing it to rotate. The first bevel gear 413 then drives the sliding column 415 to slide within the arc-shaped through hole 41, which in turn drives the mounting frame 416 to rotate, facilitating bending inspection. Simultaneously, the belt 43 drives another pulley 44 to rotate, which in turn drives the drive rod 412 to rotate. The drive rod 412 then drives the drive gear 410 to rotate, engaging the gears and driving the gears... Plate 47 slides downward on mounting bracket 2, while toothed plate 47 drives stabilizing plate 46 to slide downward on mounting bracket 2. Simultaneously, stabilizing plate 46 drives extrusion plate 48 and pressure sensor 49 to extrude plastic drain pipe. Pressure sensor 49 is electrically connected to pressure display instrument 45, which facilitates simultaneous detection of compressive strength and bending strength. This facilitates the detection of compressive strength of plastic drain pipe under bending conditions, facilitates quality inspection of plastic drain pipe, and allows for multi-dimensional quality assessment of plastic drain pipe, thereby improving the detection capability of the device.

[0034] The fixing unit includes a screw 419, a cover plate 417 rotatably mounted on the mounting frame 416, a fixing block 411 fixedly mounted on the side of the mounting frame 416 away from the cover plate 417, the screw 419 threaded through and mounted on the fixing block 411, and a fixing plate 418 rotatably mounted on the end of the screw 419 away from the testing table 1. After covering the cover plate 417, the fixing plate 418 is rotated to tighten the screw 419, which facilitates the limiting and fixing of the drain pipe within the mounting frame 416. This minimizes the possibility of the drain pipe falling off the mounting frame 416 when the device is bent too much, thus improving the safety and stability of the device.

[0035] The elastic component 6 includes a second spring 62, which is fixedly installed on the inner bottom wall of the mounting frame 416. The second spring 62 elastically drives the arc-shaped plate 61 to clamp the drain pipe inside the mounting frame 416, facilitating flexible clamping of different types of plastic drain pipes. The arc-shaped plate 61 is fixedly installed at one end of the second spring 62 near the cover plate 417. Slide grooves 63 are provided on the inner walls of both sides of the mounting frame 416. A slider 65 is slidably installed in the slide groove 63. The slider 65 slides in the slide groove 63, limiting the movement direction of the arc-shaped plate 61. A guide rod 64 is slidably installed through the slider 65. The two ends of the guide rod 64 are fixedly installed on the inner wall of the slide groove 63. The guide rod 64 guides and stabilizes the position of the slider 65 in the slide groove 63, which helps to improve the device's performance. The elastic clamping capability helps improve the safety and stability of the device. When using the device, first place the plastic drain pipe on the testing platform 1, and simultaneously place the plastic drain pipe on the arc plate 61 inside the mounting frame 416. Then rotate the cover plate 417 to squeeze the plastic drain pipe, and at the same time, the arc plate 61 squeezes the second spring 62, putting the second spring 62 in a compressed state. Simultaneously, the arc plate 61 drives the slider 65 to slide in the slide groove 63, and the slider 65 slides on the guide rod 64. Then rotate the fixing plate 418 to move onto the cover plate 417. Finally, tighten the screw 419, causing the screw 419 to rotate on the fixing plate 418 and drive the fixing plate 418 to squeeze the cover plate 417, which facilitates the installation and limiting of the plastic drain pipe and helps improve the safety and stability of the device.

[0036] The clamping assembly 7 includes a clamping plate 73. An installation groove 71 is provided on the testing table 1. Electric telescopic rods 72 are fixedly installed on the inner walls of both ends of the installation groove 71. The clamping plate 73 is fixedly installed at corresponding positions of the two electric telescopic rods 72. The electric telescopic rods 72 drive the clamping plate 73 to squeeze the drain pipe on the testing table 1. An anti-slip pad 74 is fixedly installed on the end of the clamping plate 73 away from the electric telescopic rods 72. The anti-slip pad 74 increases the friction between the clamping plate 73 and the drain pipe. When using the device, first activate the electric telescopic rods 72, causing them to slide the clamping plate 73 within the installation groove 71. Simultaneously, the clamping plate 73 drives the anti-slip pad 74 to squeeze the plastic drain pipe, facilitating the positioning and fixing of the plastic drain pipe, facilitating bending testing, improving the stability of the device, and enhancing the safety of the testing process.

[0037] A gasket 10 is fixedly installed on the testing table 1 at the position corresponding to the extrusion plate 48. The gasket 10 serves to place the drain pipe.

The calibration plate 8 facilitates the insertion of the protective cover 3 into the limiting groove 9. The protective cover 3 is slidably installed in the limiting groove 9, which serves to limit and stabilize the protective cover 3. A limiting component 5 is provided on the testing table 1.

[0038] The limiting assembly 5 includes a limiting plate 54. A sliding plate 51 is slidably mounted on the detection table 1, and the sliding plate 51 serves to limit and stabilize the limiting plate 54. A baffle 53 is fixedly mounted on the end of the sliding plate 51 near the first bevel gear 413, and the baffle 53 serves to limit and stabilize the first spring 52. The first spring 52 is fixedly mounted on the side of the baffle 53 near the sliding plate 51. The limiting plate 54 is fixedly mounted on the end of the sliding plate 51 away from the baffle 53, and the other end of the limiting plate 54 slides through the limiting groove 9. A limiting hole 56 is opened on the protective cover 3 at the position corresponding to the limiting plate 54. A pull rod 55 is fixedly mounted on the side of the limiting plate 54 away from the sliding plate 51. The end of the first spring 52 away from the baffle 53 is fixedly mounted on the inner wall of the detection table 1, and the first spring 52 is nested in place. On the outer surface of the slide plate 51, the first spring 52 acts as a spring to elastically reset the limiting plate 54. When using the device, first pull the lever 55 to pull the limiting plate 54 out of the limiting groove 9. At the same time, the limiting plate 54 causes the slide plate 51 to slide on the testing table 1. Simultaneously, the slide plate 51 causes the baffle 53 to squeeze the first spring 52, so that the first spring 52 is in a compressed state. Then, the protective cover 3 is placed on the testing table 1, and the protective cover 3 is inserted into the limiting groove 9 under the action of the calibration plate 8. Then, the lever 55 is released, and the limiting plate 54 is inserted into the limiting hole 56 on the protective cover 3 under the elastic action of the first spring 52. This facilitates the installation of the protective cover 3, makes installation and disassembly convenient, and improves the limiting stability of the protective cover 3.

[0039] The working principle of this invention is as follows: When using the device, first place the plastic drain pipe on the pad 10 on the testing platform 1, and simultaneously place the plastic drain pipe on the arc-shaped plate 61 inside the mounting frame 416. Then rotate the cover plate 417 to squeeze the plastic drain pipe, and simultaneously squeeze the second spring 62 on the arc-shaped plate 61, so that the second spring 62 is in a compressed state. At the same time, the arc-shaped plate 61 drives the slider 65 to slide in the slide groove 63, and simultaneously the slider 65 slides on the guide rod 64. Then rotate the fixing plate 418 to move onto the cover plate 417. Finally, tighten the screw 419 to make the screw 41... 9 rotates on the fixed plate 418, causing the fixed plate 418 to press against the cover plate 417. Then, the electric telescopic rod 72 is activated, causing the electric telescopic rod 72 to drive the clamping plate 73 to slide within the mounting groove 71. At the same time, the clamping plate 73 drives the anti-slip pad 74 to press against the plastic drain pipe. Then, the motor 42 is activated, causing the output end of the motor 42 to drive one of the pulleys 44 to rotate. At the same time, the pulley 44 drives the second bevel gear 414 to rotate. Simultaneously, the second bevel gear 414 meshes with and drives the first bevel gear 413 to rotate. Simultaneously, the first bevel gear 413 drives the sliding column 415 to rotate in an arc. The sliding pin 415 slides within the through hole 41, simultaneously causing the mounting frame 416 to rotate, facilitating bending detection. Simultaneously, the belt 43 drives another pulley 44 to rotate, which in turn drives the drive rod 412 to rotate. The drive rod 412 then drives the drive gear 410 to rotate, causing the drive gear 410 to mesh and slide the toothed plate 47 downwards on the mounting bracket 2. The toothed plate 47 also drives the stabilizing plate 46 to slide downwards on the mounting bracket 2. Simultaneously, the stabilizing plate 46 drives the extrusion plate 48 and pressure sensor 49 to extrude the plastic drain pipe. The pressure sensor 49 is electrically connected... With a pressure display 45, pull the lever 55 to pull the limiting plate 54 out of the limiting groove 9. At the same time, the limiting plate 54 drives the slide plate 51 to slide on the testing table 1. Simultaneously, the slide plate 51 drives the baffle 53 to squeeze the first spring 52, so that the first spring 52 is in a compressed state. Then, take the protective cover 3 and place it on the testing table 1. Under the action of the calibration plate 8, the protective cover 3 is inserted into the limiting groove 9. Then, release the lever 55. At the same time, under the elastic action of the first spring 52, the limiting plate 54 is inserted into the limiting hole 56 on the protective cover 3 to facilitate the limiting installation of the protective cover 3.
