[0002] After the forming process, stainless steel pipes also need to go through surface treatment, straightening and other processing processes. The straightening process is to eliminate the horizontal surface deviation generated during the forming process of the stainless steel pipe so that the levelness of the stainless steel pipes leaving the factory meets the production standards. For this reason, before leaving the factory, the levelness of the outer wall of the stainless steel pipe needs to be tested for horizontal surface to ensure the quality of the stainless steel pipe when leaving the factory. In the existing technology, the horizontal surface detection of stainless steel pipes is generally performed manually using detection tools such as spirit levels, and there are also problems with low efficiency and errors during manual operation that affect the accuracy of the detection.

DETAILED DESCRIPTION

[0021] The following is a combination of the appended examples of the present invention Figure 1-4 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] As shown in the figure, a horizontal straight surface detection device for a stainless steel pipe includes a base 1, on which a detection mechanism 2 and a first support frame 3 and a second support frame 4 located on both sides of the detection mechanism 2 are provided. The detection mechanism 2 includes a moving frame 21 and a detection component 22. The moving frame 21 slides on the base 1 and is transmission-connected to a first motor 13 provided on the base 1. The detection component 22 includes a telescopic rod 221, a wheel frame 222, a limit plate 223, a test thimble 224, a pressure sensor 225 and a spring 226. The telescopic rod 221 is slidably provided on the moving frame 21 so that the inner end of the telescopic rod 221 faces the moving frame. 21 center, the mobile frame 21 is formed with a support plate 211 located on one side of the sliding path of the telescopic rod 221, the limit plate 223 is fixedly connected to the outer end of the telescopic rod 221 and is slidably set on the support plate 211, the wheel frame 222 is fixedly connected to the inner end of the telescopic rod 221 and the wheel frame 222 is rotatably connected to the abutment wheel 227, the spring 226 is sleeved on the telescopic rod 221 and located between the wheel frame 222 and the mobile frame 21, the test ejector 224 is fixedly connected to the limit plate 223 and is parallel to the telescopic rod 221, and the pressure sensor 225 is arranged on the support plate 211 opposite to the test ejector 224.

[0023] Specifically, the movable frame 21 is slidably arranged on the base 1: the base 1 is provided with two first linear guide rails 11 located below the movable frame 21, the movable frame 21 is fixedly connected to the sliding seat of the first linear guide rail 11, and the base 1 is rotatably provided with a first transmission screw 12 that is screwed to the movable frame 21, and the first transmission screw 12 is connected to the output shaft of the first motor 13.

[0024] Specifically, the limit plate 223 is slidably arranged on the support plate 211: the support plate 211 is U-shaped and a second linear slide rail 213 is provided on each of the two vertical parts of the support plate 211, and the limit plate 223 is fixedly connected to the sliding seat of the second linear slide rail 213.

[0025] Through the above structure, when the stainless steel pipe is horizontally tested, the stainless steel pipe is moved from the center of the movable frame 21 so that the two ends of the stainless steel pipe are placed on the first support frame 3 and the second support frame 4 respectively. The wheel frame 222 drives the telescopic rod 221 to slide toward the movable frame 21 under the push of the spring 226, so that the abutting wheel 227 abuts against the outer wall of the stainless steel pipe. At this time, there is a certain distance between the end of the test pin 224 and the pressure sensor 225. The distance is within the horizontal error within the allowable range of the stainless steel pipe. When the telescopic rod 221 slides, the limit plate 223 The telescopic rod 221 slides on the second linear guide rail 213 to ensure the stability and accuracy of the telescopic rod 221 when sliding, and the limit plate 223 limits the sliding of the telescopic rod 221 on the moving frame 21 to prevent the telescopic rod 221 from escaping from the moving frame 21 under the action of the spring 226. Then, the first motor 13 drives the first transmission screw 12 to rotate, and the first transmission screw 12 drives the moving frame 21 to slide on the first linear guide rail through the screw connection with the moving frame 21, that is, the moving frame 21 moves along the length direction of the stainless steel pipe. During the process, the abutment wheel 227 is always against the outer wall of the stainless steel pipe under the action of the spring 226. When the levelness of the outer wall of the stainless steel pipe fluctuates, the abutment wheel 227 will be driven to move in the sliding direction of the telescopic rod 221. The abutment wheel 227 drives the test ejector 224 to move in the sliding direction of the lifting and retracting rod through the transmission of the wheel frame 222, the telescopic rod 221 and the limit plate 223, and the horizontal deviation of the outer wall of the stainless steel pipe is converted into the displacement of the test ejector 224. When the horizontal deviation of the outer wall of the stainless steel pipe exceeds the allowable range, the test ejector 224 is Driven by the abutment wheel 227, the abutment wheel 227 contacts the pressure sensor 225 and triggers the pressure sensor 225. The pressure sensor 225 can transmit the data to the control center to obtain the test result of whether the horizontality of the outer wall of the stainless steel pipe meets the standard, thereby realizing the horizontal surface detection of the stainless steel pipe. It can be seen that this stainless steel pipe horizontal surface detection device can conveniently and accurately detect the horizontal surface of the stainless steel pipe, eliminating the trouble of manual detection, effectively improving the detection efficiency, and eliminating the errors during manual operation, thereby ensuring the accuracy of the horizontal surface detection.

[0026] In addition, the base 1 is provided with two guide rods 14 located above the moving frame 21 and parallel to the first linear guide rail 11. The moving frame 21 is fixedly connected with two guide blocks 212 respectively passed through the two guide rods 14. The guide blocks 212 slide on the guide rods 14 while the moving frame 21 slides on the first linear slide rail. The cooperation between the guide blocks 212 and the guide rods 14 enhances the stability and accuracy of the moving frame 21 during movement, thereby ensuring the stability and accuracy of the horizontal surface detection of the stainless steel pipe.

[0027] In addition, another set of sliding seats provided on the second linear slide 213 is fixedly connected to a mounting plate 228, and the pressure sensor 225 is provided on the mounting plate 228. The mounting plate 228 is rotatably connected to an adjusting screw 229 screwed on the horizontal portion of the support plate 211. By rotating the adjusting screw 229 to move it in the sliding direction of the telescopic rod 221, the mounting plate 228 is driven to move in the sliding direction of the telescopic rod 221, so that when the abutting wheel 227 abuts against the outer wall of the stainless steel pipe, the distance between the test pin 224 and the pressure sensor 225 is achieved, and the allowable deviation range of the horizontality of the outer wall of the stainless steel pipe is adjusted, thereby adjusting the test accuracy to meet different test requirements.

[0028] In addition, a sealing plate 214 is fixedly connected to each of the two openings of the support plate 211. After the sealing plate 214 closes the opening of the support plate 211, the test ejector pin 224 and the pressure sensor 225 are placed in a relatively closed space, thereby reducing the interference of the external environment on the cooperation between the test ejector pin 224 and the pressure sensor 225, thereby ensuring the accuracy of the test results.

[0029] In addition, an adjustment slot 215 is provided on one of the sealing plates 214, and an indicating pointer 2281 passing through the adjusting slot 215 is fixedly connected to the mounting plate 228. The indicating pointer 2281 points to the scale on one side of the adjusting slot 215, and serves as an indicator when the position of the mounting plate 228 and the pressure sensor 225 is adjusted by rotating the adjusting screw 229, thereby facilitating the operation of adjusting the allowable deviation value of the test.

[0030] In addition, a number of detection components 22 are arranged in a circular array along the center of the movable frame 21, which can simultaneously detect the horizontality of the outer wall of the stainless steel pipe in multiple directions, thereby improving the accuracy of the test. Of course, by adjusting the position of the pressure sensor 225 by adjusting the screw 229, so that the distance between it and the test pin 224 is far greater than the test allowable deviation value, the group of detection components 22 will not participate in the detection, so that the direction of horizontal straight surface detection of the stainless steel pipe can be freely selected according to needs.

[0031] Furthermore, the first support frame 3 can be slidably arranged on the base 1 along the sliding path of the movable frame 21 and is transmission-connected to the second motor 17 arranged on the base 1, and the first support frame 3 is provided with a first material rack 31 having a V-shaped groove, and the second support frame 4 is fixedly arranged on the base 1 and the second base 1 is provided with a second material rack 41 having a V-shaped groove.

[0032] Specifically, the first support frame 3 is slidably arranged on the base 1: the base 1 is provided with two third linear slide rails 15 located below the first support frame 3, the first support frame 3 is fixedly connected to the sliding seat of the third linear slide rail 15, and the base 1 is rotatably provided with a second transmission screw 16 screwed to the first support frame 3, and the second transmission screw 16 is connected to the output shaft of the second motor 17.

[0033] Through the above structure, the second motor 17 drives the second transmission screw 16 to rotate, and the second transmission screw 16 drives the first support frame 3 to slide on the third linear slide rail 15 through the screw connection with the first support frame 3, thereby adjusting the distance between the first support frame 3 and the second support frame 4, and adapting to the horizontal straight surface detection of stainless steel pipes of different lengths. By moving the first support frame 3, the operation of passing the stainless steel pipe through the moving frame 21 can be facilitated. After the stainless steel pipe passes through the moving frame 21, the two ends of the stainless steel pipe are respectively placed in the V-grooves of the first material rack 31 and the second material rack 41. Through the movement of the first support frame 3, the side walls of the V-grooves of the first material rack 31 and the second material rack 41 are tightly pressed against the end surface of the stainless steel pipe to clamp and fix the stainless steel pipe, thereby ensuring the stability of the stainless steel pipe during the detection process, thereby ensuring the accuracy of the detection results.

[0034] Furthermore, the first material rack 31 and the second material rack 41 are respectively slidably arranged on the first support frame 3 and the second support frame 4 through the fifth linear slide rail 42 and the fifth linear slide rail 42, and the first support frame 3 and the second support frame 4 are respectively rotatably provided with a third transmission screw 33 and a fourth transmission screw 43 screwed to the first material rack 31 and the second material rack 41. The third transmission screw 33 and the fourth transmission screw 43 are respectively connected to the output shafts of the third motor 34 and the fourth motor 44 respectively provided on the first support frame 3 and the second support frame 4.

[0035] Through the above structure, the third motor 34 and the fourth motor 44 can respectively drive the first material rack 31 and the second material rack 41 to slide longitudinally on the fourth linear slide 32 and the fifth linear slide 42 by driving the third transmission screw 33 and the fourth transmission screw 43 respectively. Therefore, when stainless steel pipes of different diameters are placed in the V-grooves of the first material rack 31 and the second material rack 41, the axial position of the stainless steel pipe is adjusted by the longitudinal movement of the first material rack 31 and the second material rack 41 so that it is on the same horizontal plane as the center of the movable frame 21, thereby adapting to the level value detection of stainless steel pipes of different diameters.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
