Description

Technical Field

[0001] The invention relates to the technical field of spring detection, in particular to a spring pressure detection device. Background Art

[0002] The shock-absorbing spring is an important component of the suspension system of new energy vehicles. It is usually made of high-strength metal materials, such as spring steel. Its main function is to absorb and buffer the vibration and impact caused by uneven road conditions during vehicle driving. After the spring is produced, it is necessary to test the spring mechanical parts through a pressure testing machine to measure the force value change, deformation, elastic coefficient and other parameters of the spring under different degrees of tension and compression. When testing the spring, the spring is placed on a platform, and then the pressure mechanism above moves downward, and the spring is pressed to test it. During the spring placement process, the spring needs to be placed in the center of the test platform. If the spring is not placed properly, If the spring is not stable and centered enough, the spring will deviate during the pressing process and then pop out. The popping out of the spring may cause harm to the operator, such as hitting body parts, causing abrasions, bruises or even more serious injuries. The popped out spring may collide with other parts of the test equipment, causing damage to the equipment and increasing maintenance costs. In the spring testing process, the springs are mostly placed manually. Manual operation cannot ensure that the spring is accurately and stably placed in the center of the testing platform every time, and placement position deviation is prone to occur. Manual placement of the spring requires a certain amount of time to adjust the position, which increases the time of the entire testing process and reduces the testing efficiency.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1

[0031] Reference Figure 2-Figure 4 and Figure 8 , is the first embodiment of the present invention, which provides a spring pressure detection device, which includes a positioning assembly 200, including a fixed sleeve 201a, a support plate 201b, a clamping plate 201c, a turntable 201d, a connecting plate 201e and a guide shaft 201f, the support plate 201b is located above the fixed sleeve 201a, the clamping plate 201c is arranged on the top of the support plate 201b, the turntable 201d is located below the support plate 201b, the connecting plate 201e is fixed to the bottom of the clamping plate 201c, the guide shaft 201f is fixed to the bottom of the connecting plate 201e, a slide groove 201b-1 is provided on the support plate 201b, the connecting plate 201e is movably connected with the slide groove 201b-1, a guide groove 201d-1 is provided on the turntable 201d, and the guide shaft 201f slides in the guide groove 201d-1.

[0032] The guide groove 201d-1 is arc-shaped. When testing the spring, the spring is placed on the top of the support plate 201b. At this time, the support plate 201b will move downward and cause the turntable 201d to rotate. The cooperation between the guide groove 201d-1 and the guide shaft 201f drives the connecting plate 201e to move, so that the connecting plate 201e drives the clamping plate 201c to move, and the clamping plate 201c pushes the spring to move, so that the spring moves to the top of the support plate 201b. In this way, the spring can be placed in the center to avoid deviation in the placement position of the spring, and the clamping plate 201c can be used to squeeze the outer side of the bottom of the spring to clamp and position the spring, thereby avoiding the spring from deflecting during the pressing process, which will cause the spring of the new energy vehicle suspension system to pop out.

[0033] The trigger assembly 300 is arranged on the positioning assembly 200, and includes a positioning sleeve 301a, a movable column 301b, a first spring 301c, an electromagnet 301d, a force rod 301e, a positioning block 301f, a positioning column 301g, an electrode sheet 301h and a fixed shaft 301i. The positioning sleeve 301a is fixed in the fixed sleeve 201a, the movable column 301b is fixed to the bottom of the support plate 201b, the two ends of the first spring 301c are respectively fixed to the movable column 301b and the inner bottom wall of the fixed sleeve 201a, and the number of electromagnets 301d is two, and the two electromagnets 301d are respectively fixed to the bottom of the movable column 301b and the fixed sleeve 201 a is fixed on the inner bottom wall, the force-bearing rod 301e is located above the support plate 201b, the support plate 201b is provided with a groove 201b-2, the positioning block 301f is fixed in the groove 201b-2, the positioning column 301g is fixed to the bottom of the force-bearing rod 301e and is movably connected with the positioning block 301f, there are two electrode sheets 301h, the two electrode sheets 301h are respectively fixed to the bottom of the positioning block 301f and sleeved on the outside of the positioning column 301g, the fixed shaft 301i is fixed in the turntable 201d, the positioning sleeve 301a is provided with a spiral groove 301a-1, and the fixed shaft 301i slides in the spiral groove 301a-1.

[0034] When the two electromagnets 301d are energized, a repulsive force is generated, which pushes the upper electromagnet 301d upward. When the two electrode sheets 301h are in contact, the electromagnet 301d is energized. When the two electrode sheets 301h are separated, the electromagnet 301d is de-energized.

[0035] When the spring of the new energy vehicle suspension system is placed on the top of the support plate 201b, the force-bearing rod 301e will be pressed downward, so that the positioning column 301g can be driven to move downward through the force-bearing rod 301e, and the positioning column 301g can drive the electrode sheet 301h below to separate from the electrode sheet 301h above. At this time, the electromagnet 301d is powered off, and a downward pulling force is applied to the movable column 301b through the first spring 301c, so that the support plate 201b can be driven to move downward through the movable column 301b. When the support plate 201b moves downward, it will also drive the turntable 201d to move downward, so that the turntable 201d can be driven to rotate through the cooperation of the fixed shaft 301i and the spiral groove 301a-1.

[0036] Example 2

[0037] Reference Figure 1-Figure 8 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0038] Specifically, it also includes a locking assembly 400, which is arranged on the clamping plate 201c, including a plug plate 401a, a connecting block 401b, a connecting column 401c, a second spring 401d, a limiting column 401e, a rotating rod 401f, a stopper 401g and a supporting block 401h, the plug plate 401a is plugged into the clamping plate 201c, the connecting block 401b is fixed to the bottom of the plug plate 401a, one end of the connecting column 401c is fixed to the clamping plate 201c, and the other end is connected to the movable part of the connecting block 401b. Dynamic connection, the two ends of the second spring 401d are respectively fixed to the connecting block 401b and the clamping plate 201c, a limiting hole 401c-1 is provided on the connecting column 401c, the limiting column 401e is inserted into the limiting hole 401c-1, the rotating rod 401f is located below the connecting column 401c, the stopper 401g is fixed to the bottom end of the limiting column 401e, the supporting block 401h is fixed to one side of the clamping plate 201c, and the center of the rotating rod 401f is rotatably connected to the supporting block 401h through a rotating shaft.

[0039] The number of locking assemblies 400 corresponds to the clamping plate 201c. When the limiting column 401e is engaged with the limiting hole 401c-1, the connection block 401b and the plug plate 401a can be locked through the cooperation of the two, so that the plug plate 401a cannot move toward the spring under test, thereby preventing the plug plate 401a from being inserted into the gap of the spring during the test, thereby affecting the detection accuracy of the spring.

[0040] The rotating rod 401f is movably connected to the clamping plate 201c, and one side extends to the inner side of the clamping plate 201c. The end of the rotating rod 401f close to the detected spring is in a long strip shape and contacts the bottom circle of the detected spring.

[0041] When the tested spring is deflected due to external force during the test and is about to pop out, the deflected spring will contact the end of the rotating rod 401f and push the rotating rod 401f to move downward, so that the other end of the rotating rod 401f drives the limiting column 401e to move downward, so that the limiting column 401e is in the limiting hole 401c-1, and the rotating rod 401f is located below the connecting column 401c, and the stopper 401g is separated, thereby releasing the restriction on the connecting block 401b, and the connecting block 401b and the plug plate 401a are pulled by the second spring 401d to move, so that the plug plate 401a is inserted into the inside of the tested spring, so that the tested spring can be locked and cannot pop out, thereby avoiding injury to the operator.

[0042] Specifically, a support sleeve 202a is movably connected to the outside of the turntable 201d, a stabilizing block 202b is fixed to one side of the support sleeve 202a, a stabilizing frame 202c is fixed to the bottom of the support plate 201b, the stabilizing block 202b is movably connected to the inside of the stabilizing frame 202c, a third spring 202d is fixed to the top of the stabilizing block 202b, and the top of the third spring 202d is fixed to the inner wall of the stabilizing frame 202c.

[0043] There are two stabilizing blocks 202b and two stabilizing frames 202c, which are respectively located on both sides of the support sleeve 202a. The two are used to connect the support sleeve 202a with the support plate 201b, so that when the support plate 201b moves downward, it can drive the support sleeve 202a to move downward, so that the support sleeve 202a can drive the turntable 201d to move downward, and when the clamping plate 201c contacts the detected spring, causing the turntable 201d to be unable to rotate, if the support plate 201b continues to move downward, it can squeeze the third spring 202d, and thus will not limit the downward movement of the support plate 201b, thereby being able to clamp springs of different sizes in the center.

[0044] Specifically, the electrode sheet 301h fits tightly against the outer side of the positioning column 301g, a connecting rod 302a is fixed to one side of the electrode sheet 301h, a stabilizing column 302b is fixed to the bottom of the support plate 201b, and the stabilizing column 302b is movably connected to the inner side of the connecting rod 302a.

[0045] The electrode sheet 301h can be moved upward on the outside of the positioning column 301g by external force. When the positioning column 301g moves downward, it can drive the electrode sheet 301h on its outside to move downward and separate the two electrode sheets 301h. If it is necessary to take away the detected spring, just push the connecting rod 302a upward, and drive the electrode sheet 301h on the outside of the positioning column 301g to move upward through the connecting rod 302a, so that the two electrode sheets 301h can be brought into contact, and the electromagnet 301d can be energized, and the movable column 301b can be pushed upward by the cooperation of the two, so that the splint 201c can be separated from the detected spring, and then the detected new energy vehicle suspension system spring can be taken away.

[0046] Specifically, a support column 203a is fixed in the slide groove 201b-1, and the support column 203a is movably connected to the connecting plate 201e. A fourth spring 203b is fixed on one side of the connecting plate 201e, and one end of the fourth spring 203b is fixed to the inner wall of the slide groove 201b-1.

[0047] The support column 203a is used to position the connecting plate 201e to prevent it from being offset during movement. The fourth spring 203b is used to apply a thrust to the connecting plate 201e so that it can be reset after the restriction is released, thereby driving the clamping plate 201c to separate from the detected spring.

[0048] Specifically, a fifth spring 303 is fixed to the bottom of the force-bearing rod 301e, and the bottom end of the fifth spring 303 is fixed to the movable column 301b.

[0049] When the spring on the top of the support plate 201b is removed, the fifth spring 303 can push the force-bearing rod 301e to return to its original position.

[0050] Example 3

[0051] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0052] Specifically, a protrusion 201c-1 is fixed to one side of the bottom of the clamping plate 201c. The clamping plates 201c are arc-shaped, and there are four of them, which are evenly distributed in a ring shape on the top of the supporting plate 201b.

[0053] The protrusion 201c-1 is arc-shaped. By squeezing the bottom of the spring to be detected by the protrusion 201c-1, it is possible to prevent the clamping plate 201c from having too much contact area with the spring to be detected, thereby affecting the accuracy of spring detection.

[0054] Specifically, a push block 301g-1 is fixed to the bottom of the positioning column 301g, and the top of the push block 301g-1 is in contact with the electrode sheet 301h.

[0055] When the positioning post 301g moves upward, it drives the push block 301g-1 to press the electrode sheet 301h, so that the two electrode sheets 301h can contact each other.

[0056] Specifically, a through slot 401f-1 is provided on the rotating rod 401f, the limiting column 401e is slidably connected to the through slot 401f-1, and the bottom of the rotating rod 401f is in contact with the stopper 401g.

[0057] When one end of the rotating rod 401f moves downward, it presses the stopper 401g downward, thereby driving the limiting column 401e to move downward through the stopper 401g.

[0058] Specifically, it also includes a detection component 100, which is connected to the positioning component 200, including a base 101, a fixed frame 102, a movable frame 103 and a detection mechanism 104, the fixed sleeve 201a is fixed to the top of the base 101, the fixed frame 102 is arranged on the top of the base 101, the movable frame 103 is located in the fixed frame 102, and the detection mechanism 104 is arranged at the bottom of the fixed frame 102.

[0059] The movable frame 103 can move up and down in the fixed frame 102, and the detection mechanism 104 can be driven to move up and down through the movable frame 103. The detection mechanism 104 can test the mechanical parts, so that the spring can be tested through the detection mechanism 104. This is the existing technology and will not be elaborated in this scheme. Those skilled in the art can clearly understand the working principle.

[0060] In summary, the spring pressure detection device of the present invention has the following advantages:

[0061] 1. It can automatically center the spring, thereby ensuring that the spring is placed in the center and stably on the testing platform;

[0062] 2. During the spring testing process of the new energy vehicle suspension system, a clamping force can be applied to the spring to prevent the spring from deflecting;

[0063] 3. It can center clamp springs of different sizes;

[0064] 4. If the spring is deflected and tilted due to external force, causing the spring to pop out, the spring can be completely locked so that the spring cannot pop out;

[0065] 5. The locking assembly 400 is in a retracted state under normal conditions, and thus will not interfere with the accuracy of spring detection.

[0066] During use, when testing the spring of the new energy vehicle suspension system, the tested spring will be placed on the top of the support plate 201b, and the spring will press the force-bearing rod 301e downward, so that the positioning column 301g can be driven to move downward through the force-bearing rod 301e, and the positioning column 301g drives the electrode sheet 301h below to separate from the electrode sheet 301h above. At this time, the electromagnet 301d is powered off, and a downward pulling force is applied to the movable column 301b through the first spring 301c, so that the support plate 201b can be driven to move downward through the movable column 301b. When the support plate 201b moves downward, it will also drive the turntable 201d to move downward, so that the turntable 201d can be driven to rotate through the cooperation of the fixed shaft 301i and the spiral groove 301a-1.

[0067] When the turntable 201d rotates, the connecting plate 201e is driven to move through the cooperation of the guide groove 201d-1 and the guide shaft 201f, so that the connecting plate 201e drives the clamping plate 201c to move, and the clamping plate 201c pushes the spring to move, so that the spring moves to the top of the support plate 201b, so that the spring can be placed in the center to avoid the deviation of the spring placement position, and the clamping plate 201c is used to squeeze the outer side of the bottom of the spring to clamp and position the spring, thereby avoiding the spring from being offset during the pressing process, which causes the spring to pop out.

[0068] When the tested spring is deflected due to external force during the test and is about to pop out, the deflected spring will contact the end of the rotating rod 401f and push the rotating rod 401f to move downward, so that the other end of the rotating rod 401f drives the limiting column 401e to move downward, so that the limiting column 401e is in the limiting hole 401c-1, and the rotating rod 401f is located below the connecting column 401c, and the stopper 401g is separated, thereby releasing the restriction on the connecting block 401b, and the connecting block 401b and the plug plate 401a are pulled by the second spring 401d to move, so that the plug plate 401a is inserted into the inside of the tested spring, so that the tested spring can be locked and cannot pop out, thereby avoiding injury to the operator.

[0069] After the spring detection is completed and the detection mechanism 104 is separated from the top of the spring, the connecting rod 302a is pushed to move upward, and the electrode sheet 301h on the outside of the positioning column 301g is driven to move upward through the connecting rod 302a, so that the two electrode sheets 301h can be brought into contact, and the electromagnet 301d is energized, and the two cooperate to push the movable column 301b to move upward, and the support plate 201b is reset, and the turntable 201d will rotate in the opposite direction, so that the clamping plate 201c can be separated from the spring after detection, and the spring after detection can be removed.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
