Description

Technical Field

[0001] This utility model relates to the field of refractory brick testing technology, specifically a clamping fixture for testing the hardness of refractory bricks. Background Technology

[0002] Hardness testing of refractory bricks is a crucial step in assessing their quality, durability, and applicability, directly impacting their service life and safety in high-temperature industrial equipment. The main methods for testing the hardness of refractory bricks include indentation hardness testing, rebound hardness testing, and scratch hardness testing. The appropriate method can be selected based on the type of brick, testing accuracy, and equipment conditions. Among these, the clamping fixture for refractory brick hardness testing is a core auxiliary device in the hardness testing process.

[0003] For example, Chinese patent CN219715119U, entitled "A Hardness Testing Device for Refractory Brick Production," includes a shell, a support platform, and a groove. The support platform is installed on the inner wall of the shell, and the top of the support platform has a groove. A first sleeve is installed through the outer wall of the groove, and a first support rod is installed through the inner wall of the first sleeve. A fixing plate is installed at one end of the first support rod, and the outer wall of the first support rod has a through opening. The top of the support platform has a first opening, and a locking rod is installed through the inner wall of the first opening, with one end of the locking rod passing through the through opening. The top of the support platform has a second opening, and a pull rod is installed through the inner wall of the second opening, with one end of the pull rod connected to the outer wall of the first support rod. A first spring is installed on the outer wall of the pull rod.

[0004] While the existing technologies can achieve brick hardness testing, in practical use, the clamping mechanism is not flexible enough. It is usually fixed on the testing table, which means that the clamping mechanism can only be adjusted to fix bricks of different widths, thus reducing the adaptability of the clamping mechanism to bricks of different lengths. Furthermore, the cleaning of debris generated during testing is not convenient. A certain amount of debris is usually generated during the testing process, which requires tools to collect and process the debris after each brick is tested, thus reducing the efficiency of brick testing. Therefore, it does not meet the current needs. In response, we propose a clamping fixture for testing the hardness of refractory bricks. Utility Model Content

[0005] The purpose of this invention is to provide a clamping fixture for testing the hardness of refractory bricks, so as to solve the problems mentioned in the background art, such as the lack of flexibility in adjusting the clamping mechanism and the inconvenience in cleaning up the debris generated during testing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping fixture for testing the hardness of refractory bricks, comprising an operating table, with support rods fixedly installed at the four corners of the lower end of the operating table, and a testing table fixedly installed at the upper end of the operating table. The front and rear ends of both sides of the testing table are provided with sliding grooves, which are open structures. A lead screw is installed inside the sliding groove, with both sides of the lead screw rotatably connected to the inner wall of the sliding groove. A connecting seat is sleeved on the outside of the lead screw, and the connecting seat slides and limits the movement of the sliding groove, extending to the outside of the sliding groove. A movable frame is fixedly installed at the upper end of the connecting seat. A first hydraulic telescopic device is fixedly installed at the front and rear ends of the movable frame, with the telescopic end of the first hydraulic telescopic device extending to the inside of the movable frame. A first clamping plate is fixedly installed on one side of the telescopic end of the first hydraulic telescopic device.

[0007] Preferably, servo motors are fixedly installed at the front and rear ends of both sides of the outer side of the testing platform. The output shaft of the servo motor extends into the interior of the slide groove and is fixedly connected to the lead screw. Three anti-slip protrusions are fixedly installed on both sides of the upper end of the testing platform, and the anti-slip protrusions are evenly distributed.

[0008] Preferably, a collection cavity is provided at the center of the detection station, the upper end of the collection cavity is open, and a collection box is provided inside the collection cavity, the upper end of the collection box is open, and the collection box and the collection cavity are slidably engaged.

[0009] Preferably, the collection box is provided with a cover plate at the upper end inside the collection cavity. The cover plate has a mesh structure inside, and the upper end of the cover plate is flush with the upper end of the detection platform.

[0010] Preferably, a second hydraulic telescopic device is fixedly installed at the center of the upper end of the mobile frame, the telescopic end of the second hydraulic telescopic device extends to the lower part of the mobile frame, and a second clamping plate is fixedly installed at the lower end of the telescopic end of the second hydraulic telescopic device.

[0011] Preferably, rubber pads are fixedly provided at the lower end of the second clamping plate and on the side of the first clamping plate near the center of the testing table.

[0012] Preferably, the operating platform is fixedly equipped with a detection mechanism at the upper end of the rear end of the detection platform, and a control panel is fixedly equipped at the front end of the external side of the detection platform. The control panel is electrically connected to the servo motor, the first hydraulic telescopic device, the second hydraulic telescopic device and the detection mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model can clamp and fix bricks of different lengths by means of a lead screw and a first clamping plate. Before brick testing, the bricks are placed on the testing table. The position of the moving frame is adjusted according to the length of the bricks. At this time, the servo motor is turned on by the control panel, so that the output shaft of the servo motor drives the lead screw to rotate. The lead screw drives the connecting seat to move inside the slide groove. At the same time, the moving frame fixedly connected to the connecting seat moves together until the moving frame is moved to the appropriate position. At this time, the first hydraulic telescopic device is turned on by the control panel. The first clamping plate is moved by the extension of the telescopic end of the first hydraulic telescopic device until the first clamping plate clamps and fixes the front and rear ends of the bricks, thereby improving the adaptability of the clamping mechanism to bricks of different lengths.

[0014] (2) This utility model can collect the debris generated during brick testing through the collection chamber and collection box. When brick testing is performed, the brick will generate a certain amount of debris under the action of the testing mechanism. After the brick testing is completed, the operator uses tools to clean the debris, so that the debris enters the collection box through the cover plate. Then, the brick to be tested is placed on the testing table and subsequent operations are performed until the entire brick testing is completed. At this time, the operator opens the cover plate and takes the collection box out of the collection chamber, and then the debris in the collection box is centrally processed, thereby improving the brick testing efficiency.

[0015] (3) This utility model can clamp bricks at multiple points through the second hydraulic telescopic device and the second clamping plate. Before the brick is tested, the moving frame has been adjusted to a suitable position. At this time, the operator turns on the second hydraulic telescopic device through the control panel, so that the telescopic end of the second hydraulic telescopic device extends. The extension of the telescopic end of the second hydraulic telescopic device drives the second clamping plate to move downward until the second clamping plate is moved to a suitable position. At this time, the vertical plate on one side of the second clamping plate contacts the side wall of the brick, and the lower end of the horizontal plate of the second clamping plate contacts the upper end of the brick, so as to prevent the brick from moving vertically during the test, thereby further improving the firmness of the brick clamping.
