Description

Technical Field

[0001] This invention relates to the field of compressive strength testing technology, and in particular to a gauge baffle compressive strength testing fixture. Background Technology

[0002] Track gauge baffles are key components in railway track systems, mainly used to adjust track gauge and fix the position of rails. Their structural strength and compressive strength directly affect the stability of the track and the safety of train operation. Therefore, during the manufacturing process of track gauge baffles made of new materials, strict compressive strength testing must be conducted to verify whether their mechanical properties meet the design standards.

[0003] In the existing gauge baffle compression testing process, special tooling is usually required to fix the gauge baffle on the testing equipment, and then pressure is applied by a loading device to complete the test. However, the tooling currently used for gauge baffle testing focuses on the design of the clamping structure and lacks a real-time monitoring and early warning mechanism for the displacement state of the gauge baffle during the testing process. Workers often need to visually observe or review the data later to find displacement problems, making it difficult to take timely adjustment measures during the testing process. This results in reduced testing efficiency, decreased data reliability, and other defects. Summary of the Invention

[0004] This invention relates to a gauge baffle compressive strength testing fixture, which solves the problem that current gauge baffle testing fixtures lack a real-time monitoring and early warning mechanism for the gauge baffle displacement during the testing process.

The displacement monitoring auxiliary moving groove has two sliding sliders with an isosceles trapezoidal block structure. The left end face of each sliding slider has a second threaded locking through hole that penetrates its rear end face. A first locking bolt is installed in the threaded through hole. A connecting plate is fixedly installed on the side of the left end face of each sliding slider. A rubber adhesive block is fixedly bonded to the top face of the connecting plate. The bottom face of the rubber adhesive block is in contact with the bottom face of the inner end of the clamping groove. A thin film pressure sensor is embedded in the middle area inside the rubber adhesive block.

[0006] Furthermore, a buzzer is installed on the top surface of the clamping block, and the buzzer is electrically connected to the control box; a thin-film pressure sensor is electrically connected to the control box; when the rubber bonding block is deformed by pressure, the thin-film pressure sensor senses the pressure, and the thin-film pressure sensor sends a feedback signal to the control box, which then controls the buzzer to start.

[0007] Furthermore, the top surface of the clamping block is provided with a first threaded locking through hole that communicates with the clamping groove. A first locking stud is installed in the threaded locking through hole, and a cap is fixedly installed on the top surface of the first locking stud. A clamping pressure plate is provided in the clamping groove, and the right end face of the clamping pressure plate is in contact with the right side face of the inner end of the clamping groove. A bottom block with a circular block structure is fixedly installed on the bottom end face of the first locking stud. The bottom block is rotatably connected to the top surface of the clamping pressure plate through a bearing.

[0008] Furthermore, a guide stud is fixedly installed at the middle part of the left side of the inner end of the clamping auxiliary moving groove, and the length of the guide stud is consistent with the length of the clamping auxiliary moving groove; a mating insertion hole penetrating through the right end of the left end of the position adjusting base is opened at the middle part of the left end, and the mating insertion hole is slidably inserted into the guide stud; a nut is threaded on the guide stud.

[0009] Furthermore, a guide rod is fixedly installed on the front and rear sides of the left side of the inner end of the clamping auxiliary moving groove, and the length of the guide rod is consistent with the length of the clamping auxiliary moving groove; a guide insertion hole penetrating the right end face is opened on the front and rear sides of the left end of the position adjusting base, and the two guide insertion holes are respectively slidably inserted into the two guide rods.

[0010] Furthermore, the rear end face of the base is provided with a downward auxiliary moving groove in the shape of an isosceles trapezoidal groove, which penetrates the left and right end faces of the base; a longitudinal plate is provided on the rear side of the base, and a limiting block in the shape of an isosceles trapezoidal block is fixedly installed on the front end face of the longitudinal plate, which slides into the downward auxiliary moving groove; a third threaded locking through hole penetrating the rear end face of the longitudinal plate is provided in the middle part of the front end face of the limiting block, and a second locking stud is installed in the internal thread of the third threaded locking through hole.

[0011] Furthermore, a top plate is fixedly installed on the side of the front end face of the longitudinal plate, and a set of electric push rods electrically connected to the control box are fixedly installed on the top surface of the top plate. The push rod end of the electric push rod passes through the bottom end face of the top plate, and a pressure plate is fixedly installed at the bottom end of the electric push rod. A pressure sensor is embedded in the bottom end face of the pressure plate.

[0012] This invention provides a gauge baffle compression resistance testing fixture, which has the following beneficial effects: This invention, through a sliding engagement structure between a clamping auxiliary moving groove and a position adjusting base, allows for flexible adjustment of the spacing between two symmetrical clamping blocks according to the gauge baffle specifications. Combined with a locking nut, it enables rapid lateral positioning and fixation of the gauge baffle. Simultaneously, the linkage structure between the first locking stud and the clamping pressure plate facilitates convenient vertical clamping and fixation of the gauge baffle. Furthermore, the sliding engagement between the downward-pressing auxiliary moving groove and the limiting insert allows the longitudinal plate and the pressure plate below the top plate to move laterally along the gauge baffle, precisely aligning with the area to be inspected. Based on this structure, this invention can adapt to the clamping requirements of gauge baffles of different specifications, achieving flexible adjustment and rapid fixation of the inspection position. This effectively improves the convenience, adaptability, and stability of the inspection operation, providing efficient and reliable structural support for gauge baffle compressive strength testing.

[0013] This invention uses a movable slider to move a rubber bonding block to adhere to the front and rear sides of a gauge baffle. The slider position is fixed by a first locking bolt. During pressure testing, if the gauge baffle shifts forward or backward, it will squeeze the rubber bonding block and trigger an internal thin-film pressure sensor. The sensor transmits a signal to the control box and triggers a buzzer alarm. This allows for real-time monitoring of displacement and timely alerts to staff to stop and adjust the machine, effectively avoiding deviations in test data caused by displacement and ensuring the accuracy of test results.

A pressure sensor is embedded in the bottom end face of the pressure plate 303.

[0020] The working principle of this embodiment: The clamping auxiliary moving groove 101 provided on the base 1 allows the position adjustment base 4 to slide. By moving the position adjustment base 4, the distance between the two symmetrical clamping blocks 2 can be changed. Based on this, the position of the base 4 can be adjusted by moving along the clamping auxiliary moving groove 101 according to the different specifications and dimensions of the gauge baffle. During the movement, the position adjustment base 4 can only move left and right by sliding insertion and cooperation between the guide hole 401 and the guide rod 102, so as to prevent it from disengaging from the top opening end of the clamping auxiliary moving groove 101. When clamping and fixing the gauge baffle, place both ends of it into the clamping grooves 201 of the two clamping blocks 2 respectively. At this time, move the position adjustment base 4 along the clamping auxiliary moving groove 101 until the left and right ends of the gauge baffle are in contact with the clamping grooves 201 of the two clamping blocks 2 respectively. Then, rotate the locking nut 104 along the guide stud 103 so that the nut 104 is tightly attached to the right end face of the position adjustment base 4. While realizing the position limit of the position adjustment base 4, the two clamping blocks 2 jointly realize the left and right direction limit and fixation of the gauge baffle. Then, by rotating the cap 206, the first locking stud 205 is moved downward. The bearing 2011 converts the rotational motion of the first locking stud 205 into linear motion, pushing the clamping plate 202 downward to press the gauge baffle, thus completing the vertical positioning and fixing. Based on the position adjustment base 4, the longitudinal plate 301 can be moved left and right along the lower auxiliary moving groove 105 by sliding and inserting with the limit plug 304, so that the pressure plate 303 under the top plate 3 is aligned with the area of ​​the gauge baffle that needs to be tested for pressure resistance. When the position adjustment is correct, the second locking stud 305 is locked along the third threaded locking through hole 306 by a tool, thereby fixing the position of the longitudinal plate 301. Before testing, the sliding slider 207 is slidably inserted into the displacement monitoring auxiliary moving groove 204 to move the position of the sliding slider 207 along the displacement monitoring auxiliary moving groove 204 so that the two rubber bonding blocks 209 are tightly attached to the front and rear sides of the gauge baffle. Then, the first locking bolt 208 is locked by rotating the first threaded locking through hole 2010 with a tool to limit and fix the position of the sliding slider 207. At this time, the diaphragm pressure sensor 2015 is not under pressure. When the electric push rod 302 pushes the pressure plate 303 to apply pressure to the gauge baffle for pressure resistance testing, if the gauge baffle is displaced, such as sliding back and forth, its side will squeeze the corresponding rubber bonding block 209. After the rubber bonding block 209 is deformed by pressure, the internal thin-film pressure sensor 2015 senses the pressure and immediately transmits the signal to the control box. After receiving the signal, the control box triggers the buzzer 203 to alarm, indicating that the gauge baffle has been displaced during the pressure resistance process. This realizes real-time monitoring and early warning of displacement, which can remind the staff to stop the machine in time to re-clamp and fix the gauge baffle, ensuring the accuracy of the pressure resistance test data.
