However, when testing the spring, it is still necessary to remove the spring installation and testing device in order to install the spring. However, the spring installation and testing device is usually installed and fixed with fixing bolts, which not only reduces the installation efficiency of the spring, but also reduces the testing efficiency of the spring.

[0005] A device for testing the stiffness of hot-rolled heavy-duty suspension springs is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a device for testing the stiffness of hot-rolled heavy-duty suspension springs, in order to solve the problem mentioned in the background art. Currently, by setting a clamping pad, the transmission mechanism can be started and the clamping pad can be driven by a fixed device to assist in clamping the coil spring. However, when testing the spring, it is still necessary to remove the spring installation and testing device to install the spring. However, the spring installation and testing device is generally installed and fixed with fixing bolts, which not only reduces the installation efficiency of the spring, but also reduces the testing efficiency of the spring.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a device for detecting the stiffness of hot-rolled heavy-duty suspension springs, comprising a base and a support column, wherein the bottom surface of the base is fixedly connected to the support column around its perimeter.

[0008] The top surface of the base is symmetrically equipped with support plates. A drive motor is fixedly installed on the side surface of the support plate near the top. A reciprocating screw is fixedly connected to the output end of the drive motor through the side surface of the support plate. The reciprocating screw is rotatably connected to the support plate. A stabilizing block is fixedly connected to the side surface of the support plate near the bottom. A spring-mounted detection device is attached to one side of the top surface of the stabilizing block.

[0009] Also includes:

[0010] The spring mounting detection device has mounting components symmetrically arranged on both sides inside.

[0011] The mounting components include a sleeve that is connected through the spring mounting detection device;

[0012] The sleeve has a sliding connection to a pressing block.

[0013] Preferably, a slide rod is fixedly connected to the middle of the bottom surface of the pressing block, a compression spring is sleeved on the surface of the slide rod, the top surface of the compression spring is fixedly connected to the pressing block, and the bottom surface of the compression spring is fixedly connected to the sleeve.

[0014] Preferably, the slide bar has symmetrical inclined grooves on both sides near the bottom.

[0015] Preferably, the sleeve has symmetrical grooves on both sides near the bottom, and a compression ball is movably connected inside the groove.

[0016] Preferably, the reciprocating lead screw is threaded with a threaded sleeve on its surface, and connecting plates are symmetrically installed on both sides of the bottom surface of the threaded sleeve.

[0017] Preferably, the stabilizing block has a connecting groove inside, a fixing block is fixedly installed inside the connecting groove, and a locking block is fixedly installed on the top surface of the fixing block.

[0018] Preferably, a spring connecting device is fixedly installed on the side surface of the connecting plate near the bottom.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This device for testing the stiffness of hot-rolled heavy-duty suspension springs, by setting up installation components, makes the installation and testing of the spring installation and testing device more convenient, thereby improving the installation efficiency and testing efficiency of the springs. The specific details are as follows:

[0020] 1. By setting up the installation assembly, after the spring is installed on the spring installation detection device, pressing the pressing block on the installation assembly causes the pressing block to lower the sliding rod. Simultaneously, the lowering of the pressing block compresses the spring, causing it to deform. As the sliding rod descends, the inclined groove on the sliding rod also descends. After the sliding rod descends to a certain position, the inclined groove and the compression ball are on the same horizontal plane. Since the groove is inclined, when the compression ball and the inclined groove are on the same horizontal plane, the compression ball can slide onto the inclined groove, thus preventing any protrusions on the bottom sides of the sleeve. Simultaneously, placing the spring installation detection device on the stabilizing block causes the bottom of the sleeve to engage with the inside of the locking block. Then, by loosening the pressing block, it rises under the action of the compression spring. The rise of the pressing block drives the slide rod to rise. At the same time, the two sides of the inclined groove are also inclined, which allows the inclined groove to squeeze the extrusion ball when the slide rod rises. This causes the extrusion ball to return to the inside of the groove, so that one side of the extrusion ball passes through the groove, allowing the extrusion ball to fit against the inner wall of the locking block. At the same time, the size of the locking groove inside the locking block is larger than that of the sleeve, but smaller than the part of the extrusion ball that extends out. This allows the bottom of the sleeve to lock into the inside of the locking block, so that the spring installation detection device can be installed on the stabilizing block, which facilitates the subsequent detection of the spring and improves the spring installation efficiency and spring detection efficiency.

[0021] 2. By setting up a drive motor, reciprocating lead screw, threaded sleeve, connecting plate, and spring connecting device, after installing the spring installation and detection device on the stabilizing block, by connecting one end of the spring to the spring connecting device, the drive motor is started through the control terminal, so that the drive motor can drive the reciprocating lead screw to rotate. The rotation of the reciprocating lead screw can drive the threaded sleeve to move. At the same time, a limit rod is connected through the bottom side surface of the threaded sleeve. The limit rod is fixedly connected to the support plate. Through the cooperation between the limit rod and the support plate, the threaded sleeve can move on the reciprocating lead screw. When the threaded sleeve drives the connecting plate and spring connecting device to move to the left, the spring can be stretched. When the threaded sleeve moves to the right, the spring can be compressed. Thus, the spring can be stretched and compressed on the same device, thereby improving the practicality and flexibility of the device. Attached Figure Description

[0028] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a device for testing the stiffness of hot-rolled heavy-duty suspension springs, including a base 1 and a support column 2. The bottom surface of the base 1 is fixedly connected to the support column 2 around its perimeter. A support plate 3 is symmetrically installed on the top surface of the base 1. A drive motor 4 is fixedly installed on the side surface of the support plate 3 near the top. A reciprocating screw 5 is fixedly connected to the output end of the drive motor 4 through the side surface of the support plate 3. The reciprocating screw 5 is rotatably connected to the support plate 3. A stabilizing block 8 is fixedly connected to the side surface of the support plate 3 near the bottom. A spring installation detection device 9 is attached to the top surface of the stabilizing block 8. The device also includes: symmetrically arranged installation components 10 on both sides inside the spring installation detection device 9; wherein, the installation component 10 includes a sleeve 1001 that is connected through the spring installation detection device 9; wherein, a pressing block 1002 is slidably connected inside the sleeve 1001, such as... Figure 1-5As shown, by setting the installation component 10, the installation of the spring installation detection device 9 is made more convenient, thereby improving the installation efficiency and detection efficiency of the spring. At the same time, the spring installation detection device 9 is existing technology and its working principle is the same as existing technology. The spring can be installed through the spring installation detection device 9, which facilitates subsequent detection. The spring installation detection device 9 is equipped with a display screen to record the values ​​generated during spring detection. The model of the spring installation detection device 9 is SGTH-10. The reciprocating screw 5 can rotate forward or backward according to the actual situation, and different lengths of the reciprocating screw 5 can also be selected according to the situation.

[0030] A slide rod 1003 is fixedly connected to the middle of the bottom surface of the pressing block 1002. A compression spring 1004 is sleeved on the surface of the slide rod 1003. The top surface of the compression spring 1004 is fixedly connected to the pressing block 1002, and the bottom surface of the compression spring 1004 is fixedly connected to the sleeve 1001. Sloping grooves 1005 are symmetrically formed on both sides of the slide rod 1003 near the bottom. Grooves 1006 are symmetrically formed on both sides of the sleeve 1001 near the bottom. A compression ball 1007 is movably connected inside the groove 1006. Figure 3 , 4As shown, by pressing the pressing block 1002 on the mounting assembly 10, the pressing block 1002 can drive the slide rod 1003 to descend. Simultaneously, the descent of the pressing block 1002 can also compress the compression spring 1004, causing it to deform. At the same time, as the slide rod 1003 descends, the inclined groove 1005 on the slide rod 1003 also descends. After the slide rod 1003 descends to a certain position, the inclined groove 1005 and the compression ball 1007 are on the same horizontal plane. Since the groove 1006 is inclined, when the compression ball 1007 and the inclined groove 1005 are on the same horizontal plane, the compression ball 1007 can slide onto the inclined groove 1005, thus preventing any protrusions on the bottom sides of the sleeve 1001. Simultaneously, the spring mounting detection device 9 is placed on the stabilizing block 8, so that the bottom of the sleeve 1001 is engaged with the inside of the locking block 13. Then, by loosening the pressing block 1002... 002, causing the pressing block 1002 to rise under the action of the compression spring 1004. The rise of the pressing block 1002 can drive the slide rod 1003 to rise. At the same time, the two sides of the inclined groove 1005 are also inclined, so when the slide rod 1003 rises, the inclined groove 1005 can squeeze the extrusion ball 1007, so that the extrusion ball 1007 returns to the inside of the groove 1006. Thus, one side of the extrusion ball 1007 passes through the groove 1006, so that the extrusion ball 1007 can fit against the inner wall of the locking block 13. At the same time, the size of the locking groove inside the locking block 13 is larger than that of the sleeve 1001, but smaller than the part of the extrusion ball 1007 that extends out. This allows the bottom of the sleeve 1001 to be locked inside the locking block 13, so that the spring installation detection device 9 can be installed on the stabilizing block 8, thereby facilitating the subsequent detection of the spring and improving the spring installation efficiency and spring detection efficiency.

[0031] A threaded sleeve 6 is threaded onto the surface of the reciprocating lead screw 5. Connecting plates 7 are symmetrically installed on both sides of the bottom surface of the threaded sleeve 6. A connecting groove 11 is formed inside the stabilizing block 8. A fixing block 12 is fixedly installed inside the connecting groove 11. A locking block 13 is fixedly installed on the top surface of the fixing block 12. A spring connecting device 14 is fixedly installed on the side surface of the connecting plate 7 near the bottom. Figure 1 , 2As shown in Figure 5, after the spring installation detection device 9 is installed on the stabilizing block 8, one end of the spring is connected to the spring connecting device 14. The drive motor 4 is then started via the control terminal, causing the drive motor 4 to rotate the reciprocating screw 5. The rotation of the reciprocating screw 5 causes the threaded sleeve 6 to move. A limit rod is connected through the bottom side surface of the threaded sleeve 6. The limit rod is fixedly connected to the support plate 3. Through the cooperation between the limit rod and the support plate 3, the threaded sleeve 6 can move on the reciprocating screw 5. When the threaded sleeve 6 moves the connecting plate 7 and the spring connecting device 14 to the left, the spring can be stretched. When the threaded sleeve 6 moves to the right, the spring can be compressed. This allows for both stretching and compression tests on the spring on the same device, improving the practicality and flexibility of the device. The spring connecting device 14 is existing technology and operates on the same principle as existing technology, allowing the spring to be fixedly connected to the spring connecting device 14, thus ensuring that the spring can be stretched and compressed. The spring connecting device 14 is a JSA safety type.

[0032] Working principle: Before using this device for testing the stiffness of hot-rolled heavy-duty suspension springs, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, firstly, by setting the mounting assembly 10, after the spring is installed on the spring mounting detection device 9, pressing the pressing block 1002 on the mounting assembly 10 causes the pressing block 1002 to drive the slide rod 1003 to descend. Simultaneously, the descent of the pressing block 1002 also compresses the compression spring 1004, causing the compression spring 1004 to deform. At the same time, as the slide rod 1003 descends, the inclined groove 1005 on the slide rod 1003 also descends. After 003 descends to a certain position, the inclined groove 1005 and the extrusion ball 1007 are on the same horizontal plane. Simultaneously, the groove 1006 is inclined, allowing the extrusion ball 1007 to slide onto the inclined groove 1005 when they are on the same horizontal plane. This prevents any protrusions on the bottom sides of the sleeve 1001. At the same time, the spring installation detection device 9 is placed on the stabilizing block 8, ensuring that the bottom of the sleeve 1001 is in contact with the engaging block 13. After the internal engagement, by loosening the pressing block 1002, it rises under the action of the compression spring 1004. This rise of the pressing block 1002 drives the slide rod 1003 to rise. Simultaneously, the sides of the inclined groove 1005 are also inclined, allowing the inclined groove 1005 to compress the extrusion ball 1007 as the slide rod 1003 rises. This causes the extrusion ball 1007 to return to the interior of the groove 1006, allowing one side of the extrusion ball 1007 to pass through. The groove 1006 allows the extrusion ball 1007 to fit against the inner wall of the locking block 13. At the same time, the size of the locking groove inside the locking block 13 is larger than that of the sleeve 1001, but smaller than the part of the extrusion ball 1007 that extends out. This allows the bottom of the sleeve 1001 to be locked inside the locking block 13, so that the spring installation detection device 9 can be installed on the stabilizing block 8, which facilitates the subsequent detection of the spring and improves the installation efficiency and detection efficiency of the spring.

[0033] Secondly, by setting up a drive motor 4, a reciprocating screw 5, a threaded sleeve 6, a connecting plate 7, and a spring connecting device 14, after installing the spring installation detection device 9 on the stabilizing block 8, by connecting one end of the spring to the spring connecting device 14, the drive motor 4 is started through the control terminal, so that the drive motor 4 can drive the reciprocating screw 5 to rotate. The rotation of the reciprocating screw 5 can drive the threaded sleeve 6 to move. At the same time, a limit rod is connected through the surface of the threaded sleeve 6 near the bottom. The limit rod is fixedly connected to the support plate 3. Through the cooperation between the limit rod and the support plate 3, the threaded sleeve 6 can move on the reciprocating screw 5. When the threaded sleeve 6 drives the connecting plate 7 and the spring connecting device 14 to move to the left, the spring can be stretched. When the threaded sleeve 6 moves to the right, the spring can be compressed. Thus, the spring can be stretched and compressed on the same device, thereby improving the practicality and flexibility of the device.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
