Description

Technical Field

[0001] The present invention relates to the technical field of spring detection, and specifically to a finished spring tensile elasticity detection device for spring processing. Background Art

[0002] A spring is a mechanical part that utilizes elasticity. A part made of elastic material deforms under the action of an external force and returns to its original state after the external force is removed. Springs come in a complex variety. Classified by shape, there are mainly helical springs, scroll springs, leaf springs, special-shaped springs, etc. After the springs are produced, it is necessary to detect the relevant properties of the springs, such as compressive performance, tensile performance, etc., to ensure product quality and product safety.

[0003] When the existing detection equipment conducts tensile tests on springs, it usually adopts single tests. Due to the lack of comparison data, the tests are cumbersome and inaccurate. At the same time, when detecting the tensile strength of springs, when a spring with unqualified quality is broken, due to the elastic potential energy accumulated during the spring stretching being released instantaneously, the broken springs are likely to fly everywhere, and the flying springs will pose a greater safety hazard.

[0004] In view of this, we propose a finished spring tensile elasticity detection device for spring processing. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer toFigures 1 - 5 As shown in the figure, an embodiment of the present invention is: a finished spring tensile elasticity detection device for spring processing, including

[0031] a base 1, with a stretching mechanism 12 arranged on the surface and a transmission structure arranged at the bottom;

[0032] There are six groups of stretching mechanisms 12, and each group of stretching mechanisms 12 is also provided with a turntable 134 mechanism 13 for stretching and extruding the springs to be detected.

[0033] The transmission structure is used to drive the stretching mechanism 12 to complete the stretching detection work of the device.

[0034] The turntable 134 mechanism 13 is used to select a suitable sleeve 129 according to the size of the spring to be stretched and detected, to prevent the broken springs from flying everywhere.

[0035] Support legs 2 are arranged at the bottom of the base 1. Six chutes 3 are opened on the surface of the base 1. A first rack 4 and a second rack 5 are respectively arranged on the chutes 3. A first column 6 and a second column 7 are also arranged on both sides between two chutes 3. The stretching mechanism 12 is arranged on the first rack 4, the second rack 5, the first column 6 and the second column 7. The number of the first rack 4 and the second rack 5 is three respectively, and a group of stretching mechanisms 12 are arranged at one end of each rack.

[0036] During the operation of this embodiment, through the meshing of the gear 11 with the first rack 4 and the second rack 5, the first rack 4 and the second rack 5 are driven to move on the chute 3. The gear 11 can drive the first rack 4 and the second rack 5 to move simultaneously. Since the first rack 4 and the second rack 5 are arranged on the left and right sides, the first rack 4 and the second rack 5 will move in opposite directions, so as to realize the stretching detection of the spring. At the same time, multiple groups of stretching mechanisms are set to avoid the problems of cumbersome testing and low accuracy caused by the lack of comparison data in single testing.

[0037] On the basis of the above embodiment, in another embodiment of the present invention, the stretching mechanism 12 includes a support column 126 arranged on the first rack 4. An operation board 127 is fixedly connected to the support column 126. A second hook 128 is arranged on the front of the operation board 127. A sleeve 129 is arranged on the back of the operation board 127. The stretching mechanism 12 also includes a fixing plate 121 arranged on the first column 6. A groove is opened on the fixing plate 121. A second motor 125 is arranged on the side of the first column 6. The output end of the second motor 125 penetrates the first column 6. A screw rod 122 is arranged in the groove. The screw rod 122 is connected to the output shaft of the second motor 125. A sliding plate 123 is slidably connected to the screw rod 122. A first hook 124 is arranged on the sliding plate 123.

[0038] When this embodiment is in operation, according to the size of the spring, the second motor 125 is started to drive the screw 122 to rotate, so that the sliding plate 123 moves on the screw 122. The position of the first hook 124 can be adjusted according to the size of the spring to be detected, enabling this device to adapt to springs of different sizes and facilitating the detection of the elastic force of the spring. When detecting, the spring is hung on the first hook 124 and the second hook 128. When the first rack 4 and the second rack 5 move in opposite directions, the second hook 128 is driven to move, thus realizing the tensile detection of the spring. At the same time, the sleeve 129 provided on the back of the operation plate 127 can also perform extrusion detection on the spring. When the first rack 4 and the second rack 5 move in opposite directions, the distance between the operation plates 127 on the first rack 4 and the second rack 5 also gets closer and closer. At this time, the spring can be placed in the sleeve 129. When the first rack 4 and the second rack 5 continue to move, the sleeve 129 squeezes the spring, and the extrusion detection of the spring can be completed.

[0039] Based on the above embodiment, in another embodiment of the present invention, the turntable 134 mechanism 13 includes a support plate 131. The support plate 131 is provided at the bottom of the fixed plate 121. One end of the support plate 131 is provided with a third motor 132. The output end of the third motor 132 passes through the support plate 131 and is connected to a second rotating shaft 133. The end of the second rotating shaft 133 is provided with a turntable 134. Five sleeves 135 are provided on the turntable 134.

[0040] When this embodiment is in operation, the third motor 132 drives the second rotating shaft 133 to move, causing the turntable 134 to rotate. Multiple sleeves 135 are provided on the turntable 134. When performing tensile detection, according to the size of the spring, the third motor 132 is started to rotate the turntable 134, and the sleeve 135 of the corresponding size is rotated between the two hooks for stretching inside the sleeve 135. This not only avoids the problem that the elastic potential energy accumulated during the stretching process of the spring is released instantaneously, easily causing the broken spring to fly everywhere, but also avoids the problem of the spring deforming during stretching.

[0041] Based on the above embodiment, in another embodiment of the present invention, the transmission structure includes a first motor 9. The first motor 9 is installed on the side of the support leg 2. The output end of the first motor 9 is connected to three first rotating shafts 8 through a belt 10. The first rotating shafts 8 are provided on the base 1 and penetrate through the base 1 at both ends. Gears 11 are provided at the upper ends of the first rotating shafts 8. The gears 11 are engaged with the first rack 4 and the second rack 5.

[0042] When this embodiment is in operation, the first motor 9 is started, and the three first rotating shafts are driven through the belt 10, causing the gears 11 at the tops of the first rotating shafts 8 to rotate. The gears 11 are engaged with the first rack 4 and the second rack 5, driving the first rack 4 and the second rack 5 to move in opposite directions, providing power for the detection of the spring.
