Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of pressure detection devices, and in particular relates to a pressure detection device for spring production and processing. Background Technology
[0002] A pressure testing device for spring production and processing is a specialized piece of equipment used in the spring manufacturing process. It can detect the pressure that a spring withstands under different conditions. By acquiring pressure data through corresponding sensors, measurement systems, and other components, it can determine whether the spring's performance meets production standards and ensure spring quality.
[0003] In existing pressure testing devices for spring production and processing, a single-end pressure testing method is usually adopted. This results in uneven force on the spring during the testing process, with the part near the pressure end bearing greater pressure and the part farther away bearing relatively less pressure. It is difficult to ensure the balance of force on the spring during the testing process, which can easily lead to deviations in the test results and affect the accuracy of the evaluation of spring performance and quality. This needs to be improved. Therefore, a pressure testing device for spring production and processing is proposed. Utility Model Content

Compared with the traditional single-end pressure detection method, this ensures the balance of force during the spring detection process and improves the accuracy of pressure detection.

[0008] As a further description of the above solution: the detection tube is snapped onto the bracket, and the insertion rod is threaded onto the vertical plate, which facilitates the replacement of the detection tube and the pressure detection block according to the size of the detection spring, thereby improving the applicability of the device.
[0009] Preferably, a symmetrical limiting rod is fixedly installed on the base, and the movable blocks are all slidably disposed on the limiting rod, and the size of the movable blocks is adapted to the size of the limiting rod.
[0010] As a further description of the above solution: setting a limit rod can improve the stability of the horizontal movement of the moving block, thereby ensuring the stability of the spring detection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution:
[0024] A pressure testing device for spring production and processing includes a base 1, a bracket 2 fixedly mounted on the base 1, a testing tube 3 disposed on the top of the bracket 2, symmetrical movable blocks 4 slidably mounted on the base 1, two sets of movable blocks 4 respectively disposed on both sides of the bracket 2, an mounting block 5 fixedly mounted in the middle of the base 1, a cylinder 6 fixedly mounted on one side of the movable block 4 near the mounting block 5, the output shaft end of the cylinder 6 fixedly mounted to the side of the mounting block 5, a movable strip 7 rotatably mounted on the mounting block 5, movable columns 8 rotatably mounted at both ends of the movable strip 7, the ends of the two sets of movable columns 8 respectively rotatably mounted in the middle of the movable block 4, a vertical plate 9 fixedly mounted on the top of each movable block 4, an insertion rod 10 disposed on the side of the vertical plate 9 near the testing tube 3, a pressure testing block 11 fixedly mounted at the end of each insertion rod 10, the size of the testing block being adapted to the inner diameter of the testing tube 3.
[0025] In the pressure testing device for spring production and processing, the base 1 is used to support the entire device;
[0026] During spring pressure testing, the spring is placed inside the testing tube 3, and the cylinder 6 is activated. The cylinder 6 is installed on one side of the mounting block 5 in the middle of the base 1, and its output shaft end is fixedly installed to the side of the mounting block 5. After the cylinder 6 is activated, since the two sets of movable blocks 4 are symmetrically slidably arranged on the base 1, and the side of one movable block 4 close to the mounting block 5 is connected to the output shaft of the cylinder 6, the movable block 4 on that side begins to slide on the base 1 under the pushing action of the cylinder 6. At the same time, the movable strip 7 rotatably arranged on the mounting block 5 is rotatably connected to the movable column 8 at both ends, and the ends of these movable columns 8 are respectively rotatably arranged in the middle of the movable block 4, so that when one side of the movable block 4 moves, the other side of the movable block 4 moves synchronously towards each other through the linkage of the movable strip 7 and the movable column 8.
[0027] As the two movable blocks 4 move toward each other, the pressure detection block 11 at the end of the insertion rod 10 fixed on the top vertical plate 9 of the movable block 4 near the detection tube 3 also gradually moves toward the detection tube 3. Finally, the two sets of pressure detection blocks 11 with sizes adapted to the inner diameter of the detection tube 3 are steadily inserted into the detection tube 3 from both ends of the spring, accurately applying pressure to both ends of the spring at the same time for detection.
[0028] This pressure testing device for spring production and processing can simultaneously apply pressure to both ends of the spring for testing. Compared with the traditional single-end pressure testing method, it ensures the balance of force during the spring testing process and improves the accuracy of pressure testing.
[0029] The detection tube 3 is snapped onto the bracket 2, and the insertion rod 10 is threaded onto the vertical plate 9;
[0030] The detection tube 3 is snapped onto the bracket 2, and the insertion rod 10 is threaded onto the vertical plate 9, which facilitates the replacement of the detection tube 3 and the pressure detection block 11 according to the size of the detection spring, thereby improving the applicability of the device.
[0031] A symmetrical limiting rod 12 is fixedly installed on the base 1. The movable blocks 4 are all slidably arranged on the limiting rod 12, and the size of the movable blocks 4 is adapted to the size of the limiting rod 12.
[0032] Setting a limit rod 12 can improve the stability of the horizontal movement of the movable block 4, thereby ensuring the stability of the spring detection.
[0033] A level is installed on base 1;
[0034] Setting up a level allows for easy adjustment of the entire device to a horizontal position during testing, further improving the stability of the spring test.
[0035] A controller is provided on the base 1, and the controller is electrically connected to the cylinder 6 and the pressure detection block 11 respectively;
[0036] Setting up a controller enables automatic control of the detection process.
[0037] Working principle:
[0038] In the pressure testing device for spring production and processing, the base 1 is used to support the entire device;
[0039] During spring pressure testing, the spring is placed inside the testing tube 3, and the cylinder 6 is activated. The cylinder 6 is installed on one side of the mounting block 5 in the middle of the base 1, and its output shaft end is fixedly installed to the side of the mounting block 5. After the cylinder 6 is activated, since the two sets of movable blocks 4 are symmetrically slidably arranged on the base 1, and the side of one movable block 4 close to the mounting block 5 is connected to the output shaft of the cylinder 6, the movable block 4 on that side begins to slide on the base 1 under the pushing action of the cylinder 6. At the same time, the movable strip 7 rotatably arranged on the mounting block 5 is rotatably connected to the movable column 8 at both ends, and the ends of these movable columns 8 are respectively rotatably arranged in the middle of the movable block 4, so that when one side of the movable block 4 moves, the other side of the movable block 4 moves synchronously towards each other through the linkage of the movable strip 7 and the movable column 8.
[0040] As the two movable blocks 4 move toward each other, the pressure detection block 11 at the end of the insertion rod 10 fixed on the top vertical plate 9 of the movable block 4 near the detection tube 3 also gradually moves toward the detection tube 3. Finally, the two sets of pressure detection blocks 11 with sizes adapted to the inner diameter of the detection tube 3 are steadily inserted into the detection tube 3 from both ends of the spring, accurately applying pressure to both ends of the spring at the same time for detection.
[0041] This pressure testing device for spring production and processing can simultaneously apply pressure to both ends of the spring for testing. Compared with the traditional single-end pressure testing method, it ensures the balance of force during the spring testing process and improves the accuracy of pressure testing.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
