Description

Technical Field

[0001] The invention belongs to the technical field of vibration testing, and in particular relates to a batch vibration testing device for spring buckles. Background Art

[0002] The main body of the spring buckle is composed of two circular features of different sizes. Since the spring buckle is composed of multiple independent parts such as the spring and the hinge shaft, the main failures during its use often occur in the elastic opening and closing part that needs to rotate back and forth. Therefore, for the spring buckles that have been produced, it is often necessary to sample and conduct aging tests to determine their durability and qualification.

[0003] Most of the current vibration testing devices conduct vibration and opening and closing tests of the elastic opening and closing part as two independent test items. The vibration test mainly fixes the spring buckle bodies one by one on the vibration base through a clamp, and then judges the looseness of the connection part of the spring buckle through the high-frequency vibration of the base. The opening and closing test of the elastic opening and closing part is to perform aging test directly by reciprocating the elastic opening and closing part.

[0004] The above test deviates greatly from the actual scenario, because the spring buckle is generally connected to a flexible rope or steel wire, so the impact often occurs at the same time as the elastic opening and closing part rotates and opens. Therefore, testing the vibration impact and the opening and closing of the elastic opening and closing part together can not only simplify the test steps, shorten the test time, and reduce the test cost, but also because the test is more in line with the actual usage scenario, the test results can better reflect the product life. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention proposes a batch vibration testing device for a spring buckle that controls the reciprocating opening and closing of the elastic opening and closing part by reciprocating impact; in order to simplify the structure, the present invention simultaneously drives the workpiece direction adjustment and vibration test of the workpiece direction adjustment mechanism through a reciprocating vibration component, but in the process of workpiece direction adjustment, the blocking bracket needs to slide back and forth with the L-shaped slide, otherwise a collision will occur between the spring buckle body and the blocking bracket, affecting the direction adjustment of the spring buckle body; and in the vibration test process, the blocking bracket cannot slide back and forth with the L-shaped slide, otherwise no collision will occur between the spring buckle body and the blocking bracket, and the test cannot be performed; in order to overcome this technical contradiction, the present invention creatively proposes a workpiece direction adjustment mechanism and a self-locking blocking mechanism. Through an opening and closing support component that can change its own width, on the one hand, the spring buckle body can automatically adjust its direction according to the different center of gravity positions, and on the other hand, it can automatically control the linkage of the blocking bracket through its own expansion and contraction.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a batch vibration testing device for spring buckles, including a workpiece direction adjustment mechanism, an equidistant clamping mechanism, a self-locking blocking mechanism and a base plate mechanism, the workpiece direction adjustment mechanism is arranged on the base plate mechanism, the equidistant clamping mechanism is arranged on the workpiece direction adjustment mechanism, the self-locking blocking mechanism is arranged on the base plate mechanism, and the self-locking blocking mechanism and the equidistant clamping mechanism are alternately distributed.

[0010] When the opening and closing support component is popped open, it is too wide to enter the small circle of the spring buckle body. At this time, through the design of the center of gravity position of the spring buckle body, all the spring buckle bodies can be adjusted to the state with the large circle facing up and the small circle facing down during the vibration process. After the opening and closing support component tightens itself and enters the small circle, on the one hand, it can fix the position of the small ring, and on the other hand, it can unlock the self-locking blocking mechanism through the clamping component when it tightens itself.

[0014] By the sequential rise of the equidistant clamping mechanism, on the one hand, the spring buckle body can be clamped and fixed from the bottom, so that the spring buckle body remains tight during the subsequent vibration test; on the other hand, the long slope part and the short slope part can be cooperated to separate the spring buckle body at a uniform interval, so that each group of spring buckle bodies will not collide with each other during the vibration test.

[0015] Preferably, the fixing seat lifting assembly includes a locking fixing seat, an anti-rotation plug plate and a fixing seat reset spring. A bottom guide rod is provided at the bottom of the locking fixing seat. The locking fixing seat is slidably arranged on the L-shaped slide seat through the bottom guide rod. A long slope portion and a short slope portion are also provided on the locking fixing seat. The width of the short slope portion is smaller than the thickness of the spring buckle body. The anti-rotation plug plate is engaged between the long slope portion and the short slope portion. The anti-rotation plug plate is limited to avoid deflection of the spring buckle body during the test. The fixing seat reset spring is arranged between the locking fixing seat and the L-shaped slide seat.

[0016] As a further preferred embodiment of the present invention, the fixed seat driving assembly includes a ramp slide and a driving push rod, the ramp slide is fixed to the bottom of the lock fixed seat, the driving push rod is engaged and slidably arranged on the side of the L-shaped slide, and the driving push rod is provided with a ramp block matching the ramp slide, and the ramp block is engaged and slidably arranged on the L-shaped slide.

[0017] As a further preferred embodiment of the present invention, the fixed seat limit assembly includes a limit block sliding bracket, a slope limit block body, a limit block return spring and a release handle. The limit block sliding bracket is fixedly connected to the L-shaped slide seat. The slope limit block body is provided with a limit block guide rod. The slope limit block body is slidably arranged on the limit block sliding bracket through the limit block guide rod. The limit block return spring is arranged between the slope limit block body and the limit block sliding bracket. The release handle is fixedly connected to the end of the limit block sliding bracket.

[0018] The position of the lock fixing seat can be limited by the fixing seat limit assembly, so that the lock fixing seat can remain in the current position after being pushed to the top, thereby continuously clamping and fixing the spring buckle body. After the test is completed, the lock fixing seat limit can be contacted in batches by releasing the handle, so that each group of lock fixing seats can be reset under the elastic force of the fixing seat reset spring.

[0019] Furthermore, the self-locking blocking mechanism includes a fixed side panel and a self-locking blocking assembly, the fixed side panel is provided with a side panel slide groove and a spring mounting plate, the self-locking blocking assembly includes a blocking bracket, a blocking spring and a cantilever extension rod, the blocking bracket is snap-fitted and slidably arranged in the side panel slide groove, the blocking spring is arranged between the spring mounting plate and the blocking bracket, the cantilever extension rod is fixed to the two ends of the blocking bracket, and a clamping plate is provided at the end of the cantilever extension rod, and the clamping plate is located between the first clamp and the second clamp.

[0020] Furthermore, the base plate mechanism includes a main base plate and a reciprocating vibration component, the fixed side plate is fixed to the main base plate, a sliding guide rail is provided on the main base plate, a main slide is slidably provided on the sliding guide rail, and the L-shaped slide seat is provided on the main slide.

[0023] The beneficial effects achieved by the present invention using the above structure are as follows:

[0024] (1) Through the automatic opening and closing of the workpiece direction adjustment mechanism, the locking and unlocking of the self-locking blocking mechanism can be controlled, thereby overcoming the technical contradiction that the self-locking blocking mechanism needs to follow the movement during the direction adjustment process (to avoid the collision between the blocking bracket and the spring buckle body) and the self-locking blocking mechanism needs relative movement during the vibration test (to ensure the collision between the blocking bracket and the spring buckle body).

[0025] (2) When the opening and closing support assembly is opened, its width is large and it cannot enter the small circle of the spring buckle body. At this time, through the design of the center of gravity position of the spring buckle body, all the spring buckle bodies can be adjusted to the state where the large circle faces upward and the small circle faces downward during the vibration process. After the opening and closing support assembly tightens itself and enters the small circle, on the one hand, it can fix the position of the small circle, and on the other hand, it can unlock the self-locking blocking mechanism through the clamping assembly when it tightens itself.

[0026] (3) Through the sequential rise of the equidistant clamping mechanism, on the one hand, the spring buckle body can be clamped and fixed from the bottom, so that the spring buckle body remains tight during the subsequent vibration test; on the other hand, the spring buckle body can be separated at a uniform interval through the cooperation of the long slope portion and the short slope portion, so that each group of spring buckle bodies will not collide with each other during the vibration test.

[0027] (4) The position of the lock fastener can be limited by the fixed seat limit assembly, so that the lock fastener can be kept in the current position after being pushed to the top, thereby continuously clamping and fixing the spring buckle body. After the test is completed, the limit of the lock fastener can be contacted in batches by releasing the handle, so that each group of lock fasteners can be reset under the elastic force of the fixed seat reset spring.

[0028] (5) The L-shaped slide can be made to slide back and forth by the reciprocating vibration component as a driving module.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] In the description of the present invention, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0045] like Figures 1 to 11 As shown, the present invention proposes a batch vibration testing device for spring buckles, including a workpiece direction adjustment mechanism 1, an equidistant clamping mechanism 2, a self-locking blocking mechanism 3 and a base plate mechanism 4. The workpiece direction adjustment mechanism 1 is arranged on the base plate mechanism 4, the equidistant clamping mechanism 2 is arranged on the workpiece direction adjustment mechanism 1, and the self-locking blocking mechanism 3 is arranged on the base plate mechanism 4.

[0046] The base plate mechanism 4 includes a main base plate 43 and a reciprocating vibration component 44. The fixed side plate 35 is fixed to the main base plate 43. A sliding guide rail 45 is provided on the main base plate 43. A main slide 49 is slidably provided on the sliding guide rail 45. The L-shaped slide seat 5 is provided on the main slide 49.

[0047] The reciprocating vibration assembly 44 includes a vibration motor 46, a reciprocating turntable 47 and a reciprocating connecting rod 48.

[0048] Through the reciprocating vibration component 44, the L-shaped slide 5 can slide back and forth. Under the driving action of the reciprocating vibration component 44, when the bottom of the spring buckle body 7 is not fixed, the direction of the spring buckle body 7 can be automatically adjusted through the reciprocating sliding of the L-shaped slide 5, so that the small ring part of the spring buckle body 7 faces downward; and after the bottom of the spring buckle body 7 is fixed, the reciprocating sliding of the L-shaped slide 5 can cause relative sliding between the blocking bracket 39 and the L-shaped slide 5, so that the elastic opening and closing part 13 is continuously impacted and opened and closed by the blocking bracket 39, thereby realizing a vibration test of the spring buckle body 7.

[0049] The self-locking blocking mechanism 3 includes a fixed side plate 35 and a self-locking blocking assembly 36. The fixed side plate 35 is provided with a side plate slide groove 37 and a spring mounting plate 38. The self-locking blocking assembly 36 includes a blocking bracket 39, a blocking spring 40 and a cantilevered extension rod 41. The blocking bracket 39 is engaged and slidably arranged in the side plate slide groove 37. The blocking spring 40 is arranged between the spring mounting plate 38 and the blocking bracket 39. The cantilevered extension rod 41 is fixedly connected to the two ends of the blocking bracket 39. The end of the cantilevered extension rod 41 is provided with a clamping plate 42. The clamping plate 42 is located between the clamping plate 14 and the clamping plate 2 15.

[0050] The workpiece direction adjustment mechanism 1 includes an L-shaped slide 5, an opening and closing support assembly 6, a spring buckle body 7 and a clamping assembly 8. The L-shaped slide 5 is arranged on the base plate mechanism 4, the opening and closing support assembly 6 is arranged on the L-shaped slide 5, the spring buckle body 7 array is arranged on the opening and closing support assembly 6, and the clamping assembly 8 is arranged on both sides of the L-shaped slide 5.

[0051] Through the automatic opening and closing of the workpiece direction adjustment mechanism 1, the locking and unlocking of the self-locking blocking mechanism 3 can be controlled, thereby overcoming the technical contradiction that the self-locking blocking mechanism 3 needs to follow the movement during the direction adjustment process (to avoid collision between the blocking bracket 39 and the spring buckle body 7) and the self-locking blocking mechanism 3 needs relative movement during the vibration test (to ensure collision between the blocking bracket 39 and the spring buckle body 7).

[0052] The opening and closing support assembly 6 includes a side sliding groove 9, an intermediate fixed plate 10, an arc-shaped sliding plate 11 and a stretching spring 12. The side sliding groove 9 is fixed to the inner side of the L-shaped slide 5, and the intermediate fixed plate 10 is fixed to the middle position of the side sliding groove 9. Guide round rods 16 are arranged on both sides of the intermediate fixed plate 10, and guide round sleeves 17 corresponding to the guide round rods 16 are arranged on the arc-shaped sliding plate 11. The guide round sleeves 17 are engaged and slidably arranged on the guide round rods 16. The stretching spring 12 is sleeved on the outside of the guide round rods 16 and the guide round sleeves 17, and the stretching spring 12 is arranged between the intermediate fixed plate 10 and the arc-shaped sliding plate 11.

[0053] When the opening and closing support component 6 is opened, its width is large and it cannot enter the small circle of the spring buckle body 7. At this time, through the design of the center of gravity position of the spring buckle body 7, all the spring buckle bodies 7 can be adjusted to the state with the large circle facing up and the small circle facing down during the vibration process. After the opening and closing support component 6 tightens itself and enters the small circle, on the one hand, it can fix the position of the small circle, and on the other hand, it can also unlock the self-locking blocking mechanism 3 through the clamping component 8 when it tightens itself.

[0054] An elastic opening and closing portion 13 is provided on the spring buckle body 7, and the spring buckle body 7 is arranged on the opening and closing support component 6. The clamping component 8 includes a clamping plate 14 and a clamping plate 2 15. The clamping plate 14 and the clamping plate 2 15 are engaged and slidably arranged in the L-shaped slide 5 and the side sliding groove 9. The clamping plate 14 and the clamping plate 2 15 are respectively fixed to the ends of the two arc-shaped sliding plates 11.

[0055] The first clamping plate 14 and the second clamping plate 15 can achieve the clamping, fixing and releasing and unlocking of the clamping plate 42 in the process of following the movement of the arc-shaped sliding plate 11 .

[0056] The equidistant clamping mechanism 2 includes a fixed seat lifting assembly 18, a fixed seat driving assembly 19 and a fixed seat limiting assembly 20. The fixed seat lifting assembly 18 is slidably arranged on the L-shaped slide 5, the fixed seat driving assembly 19 is arranged on the fixed seat lifting assembly 18, and the fixed seat limiting assembly 20 is arranged on the L-shaped slide 5.

[0057] By the sequential rise of the equidistant clamping mechanism 2, on the one hand, the spring buckle body 7 can be clamped and fixed from the bottom, so that the spring buckle body 7 remains tight during the subsequent vibration test. On the other hand, the long slope portion 30 and the short slope portion 31 can be used to separate the spring buckle body 7 at a uniform interval, so that each group of spring buckle bodies 7 will not collide with each other during the vibration test.

[0058] The fixed seat lifting assembly 18 includes a lock fixed seat 21, an anti-rotation plug plate 22 and a fixed seat reset spring 23. A bottom guide rod 32 is provided at the bottom of the lock fixed seat 21. The lock fixed seat 21 is slidably arranged on the L-shaped slide 5 through the bottom guide rod 32. A long slope portion 30 and a short slope portion 31 are also provided on the lock fixed seat 21. The width of the short slope portion 31 is less than the thickness of the spring buckle body 7. The anti-rotation plug plate 22 is engaged between the long slope portion 30 and the short slope portion 31. The anti-rotation plug plate 22 is limited to avoid deflection of the spring buckle body 7 during the test. The fixed seat reset spring 23 is arranged between the lock fixed seat 21 and the L-shaped slide 5.

[0059] The fixed seat driving assembly 19 includes a ramp slide 24 and a driving push rod 25. The ramp slide 24 is fixed to the bottom of the lock fixed seat 21. The driving push rod 25 is engaged and slidably arranged on the side of the L-shaped slide 5. The driving push rod 25 is provided with a ramp block 33 that matches the ramp slide 24. The ramp block 33 is engaged and slidably arranged on the L-shaped slide 5.

[0060] The fixed seat limit assembly 20 includes a limit block sliding bracket 26, a slope limit block body 27, a limit block return spring 28 and a release handle 29. The limit block sliding bracket 26 is fixed to the L-shaped slide 5. The slope limit block body 27 is provided with a limit block guide rod 34. The slope limit block body 27 is engaged and slidably arranged on the limit block sliding bracket 26 through the limit block guide rod 34. The limit block return spring 28 is arranged between the slope limit block body 27 and the limit block sliding bracket 26. The release handle 29 is fixed to the end of the limit block sliding bracket 26.

[0061] The position of the lock fixing seat 21 can be limited by the fixing seat limit assembly 20, so that the lock fixing seat 21 can remain in the current position after being pushed to the top, thereby continuously clamping and fixing the spring buckle body 7. After the test is completed, the limit of the lock fixing seat 21 can be contacted in batches by releasing the handle 29, so that each group of lock fixing seats 21 can be reset under the elastic force of the fixing seat reset spring 23.

[0062] like Figure 12 As shown, the spring buckle body 7 is composed of a large circular portion and a small circular portion spliced together, wherein the elastic opening and closing portion 13 is located on the large circular portion. When the spring buckle body 7 is just installed on the retractable support assembly 6, the small circular portion of the spring buckle body 7 may face upward or downward. Since the retractable support assembly 6 in the expanded state cannot enter the small circular portion, the two dotted circles a and b in the figure represent the positions of the retractable support assembly 6 in the above two states of the spring buckle body 7;

[0063] Since the distances between the centers of the two dotted circles a and b and the center of gravity of the spring buckle body 7 are different, specifically, a is farther away from the center of gravity of the spring buckle body 7, the state of the spring buckle body 7 is more stable when the small circular ring part faces downward. Therefore, when the L-shaped slide 5 swings back and forth, all the spring buckle bodies 7 can automatically adjust to the direction where the small circular ring part faces downward.

[0064] During specific use, the user first needs to put a specific number of spring buckle bodies 7 on the retractable support assembly 6 in batches through an external loading device or a jig when the retractable support assembly 6 is in the open state (since the elastic opening and closing portion 13 can be rotated and opened, it can be directly buckled on). At this time, since the external loading device does not distinguish the direction of the spring buckle body 7, the small ring part of the spring buckle body 7 just put on the retractable support assembly 6 may face upward or downward;

[0065] When the spring buckle body 7 is just installed on the retractable support assembly 6, the small circular portion of the spring buckle body 7 may face upward or downward. Since the retractable support assembly 6 in the expanded state cannot enter the small circular portion, Figure 12 The two dotted circles a and b represent the positions of the openable and closable support assembly 6 in the two states of the spring buckle body 7;

[0066] Then the vibration motor 46 is started, and the reciprocating turntable 47 can slide back and forth with the L-shaped slide 5 through the reciprocating connecting rod 48 during the continuous rotation; since the stability of the spring buckle body 7 in different directions is different, when the rotation speed of the vibration motor 46 is adjusted to a suitable speed, it can be ensured that when the small circular ring part of the spring buckle body 7 is facing upward, the swing of the spring buckle body 7 can rotate in its own direction, and when the small circular ring part of the spring buckle body 7 is facing downward, the swing of the spring buckle body 7 cannot rotate the spring buckle body 7. After a period of vibration, all the spring buckle bodies 7 can be adjusted to the direction with the small circular ring part facing downward.

[0067] In the above process, since the clamping plate 42 is clamped by the clamping plate 14 and the clamping plate 2 15, the sliding of the L-shaped slide 5 will also slide the blocking bracket 39, thereby avoiding collision between the blocking bracket 39 and the spring buckle body 7.

[0068] After the vibration motor 46 is turned off, the driving push rod 25 is pushed toward the inside of the L-shaped slide 5. Through the cooperation of the ramp block 33 and the ramp slide 24, each group of lock fixing seats 21 can be raised in sequence. When the lock fixing seats 21 rise, the small circular ring portion at the bottom of the spring buckle body 7 will enter the lock fixing seat 21, and the rising lock fixing seat 21 will also push the spring buckle body 7 to rise as a whole. As the spring buckle body 7 rises, the arc-shaped sliding plate 11 will overcome the elastic force of the support spring 12 and gradually approach the middle fixed plate 10; during this process, the clamping plate 14 and the clamping plate 2 15 are respectively away from the clamping plate 42;

[0069] On the other hand, since the retractable support assembly 6 is arranged in a slightly inclined manner as a whole, after vibration, all the spring hook bodies 7 will be accumulated at the end where the slope block 33 is located. The width of the short slope portion 31 is smaller than the thickness of the spring hook body 7. Therefore, when each lock fixing seat 21 rises, only one spring hook body 7 will be stuck in the gap between the long slope portion 30 and the short slope portion 31.

[0070] At the same time, when the lock fixing seat 21 rises to the top, the lock fixing seat 21 will be blocked by the sliding of the slope limit block body 27, so that the lock fixing seat 21 is kept at the top limit position;

[0071] When the ramp block 33 is pushed to the other end, all the spring buckle bodies 7 are fixed, and all the lock buckle fixing seats 21 are kept at the top limit position.

[0072] Then, the vibration motor 46 is started again, and the L-shaped slide 5 vibrates again. At this time, since the first clamping plate 14 and the second clamping plate 15 are both away from the clamping plate 42, the L-shaped slide 5 will not slide with the blocking bracket 39 during its reciprocating sliding. Therefore, the clamped spring buckle body 7 will collide with the blocking bracket 39. During the vibration test, on the one hand, the reciprocating motion of the L-shaped slide 5 tests the entire spring buckle body 7, and on the other hand, the collision between the blocking bracket 39 and the elastic opening and closing part 13 and the rotation of the elastic opening and closing part 13 test the hinge part and the spring part of the elastic opening and closing part 13.

[0073] During this process, although the blocking bracket 39 will overcome the elastic force of the blocking spring 40 and there will be a small avoidance, since the spring elastic force of the hinge part of the elastic opening and closing part 13 is relatively small, it is still sufficient to test the spring buckle body 7 and the elastic opening and closing part 13.

[0074] After the test is completed, all the slope limit block bodies 27 are pulled outward synchronously by releasing the handle 29. At this time, all the lock fixing seats 21 will be reset under the elastic force of the fixing seat reset spring 23, and the clamping fixation of the lock fixing seat 21 will be released. Then, the spring buckle body 7 can be removed and its damage degree and damage rate can be counted.
