Description

Technical Field

[0001] This utility model relates to the field of elastic components, specifically to an elasticity testing mechanism. Background Technology

[0002] In today's society, many industrial products iterate rapidly. While the previous generation of products is still active in the market, the next generation is being developed and produced simultaneously. In the production of new and old products, the new generation of products may only have some minor differences from the old products, such as the addition of some holes. If the new and old products can share a set of products, it will undoubtedly save huge costs.

[0003] In the current production process, if new and old products share the same fixture, different products need to be distinguished to prevent workers from picking up the wrong products and producing incorrect products. However, the small hole structure on some products is too small, causing the sensor to be unable to recognize it, thus resulting in low production efficiency.

[0004] Therefore, it is necessary to invent a flexible testing mechanism to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an elastic detection mechanism to solve the problem mentioned in the background art: in the current production process, if new and old products share the same fixture, different products need to be distinguished to prevent workers from picking up the wrong products and producing incorrect products. However, the small hole structure on some products is too small, causing the sensor to be unable to identify it, thus resulting in low production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an elastic detection mechanism, including a sensor bracket, wherein the sensor bracket has an internal cavity, and a sensor is fixedly inserted inside the internal cavity; the sensor bracket has a through hole, and a long rod is movably inserted inside the through hole; a sensing probe is fitted inside the long rod; a base is fixedly installed at the lower end of the long rod; a compression spring is movably fitted on the outer ring of the long rod, and a washer is fixedly installed at the end of the compression spring; the washer is movably fitted on the outer ring of the long rod, and a blocking nut is threaded onto the outer ring of the long rod; the long rod is limitedly connected to the through hole through a pre-set fastening component inside the sensor bracket.

[0007] Preferably, the long rod is composed of a rod body one and a rod body two connected together, and the outer ring of the rod body one is threaded with a blocking nut, and the lower end of the rod body two is fixedly installed with a base plate, wherein the outer ring diameter of the base plate is larger than the outer ring diameter of the rod body two, and the rod body two and the through hole are connected to the through hole by a fastening assembly to achieve a limited sliding connection.

[0008] Preferably, the fastening assembly includes a horizontal groove inside the sensor bracket, and a horizontal bar is elastically connected inside the horizontal groove through an elastic connector. The ball end of the horizontal bar matches the snap-fit ​​groove inside the rod body. Under the elastic force of the elastic connector, the horizontal bar is pressed against the snap-fit ​​groove, so that after the blocking nut is turned off from the long rod, the long rod will not slide with the through hole and thus fall off the through hole inside the sensor bracket.

[0009] Preferably, the inner wall of the locking groove is smooth, and the edge of the locking groove is arc-shaped. This way, when the long rod is pressed down, the synchronous pressing of the locking groove will hold the ball end, causing the ball end to move into the transverse groove, thus not affecting the descent of the long rod.

[0010] Preferably, the fastening assembly further includes a protrusion fixedly installed at the end of the crossbar, and the protrusion is slidably connected to the strip groove, and the strip groove is connected to the horizontal groove to ensure the stability of the crossbar in elastic movement inside the horizontal groove.

[0011] Preferably, the protrusion is square, and the outer wall of the protrusion is attached to the inner wall of the strip groove to achieve a sliding connection.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. In this utility model, the sensing probe and sensor bracket are fixed in position by being fitted inside the long rod. When the sensing probe is blocked and moves downward, the compression spring is compressed by the downward force. The long rod with the sensing probe fitted inside moves down synchronously and contacts the sensor, so that the sensor receives a signal. This can identify the differences of some small holes between different products and solve the problem that the sensor cannot identify holes that are too small. 2. After the blocking nut is turned to separate from the long rod, the compression spring pops out and, under the elastic force of the elastic connector, pushes the crossbar against the locking groove, preventing the long rod from sliding with the through hole and falling off the through hole inside the sensor bracket. This ensures that the long rod and the sensing probe installed inside the long rod will not separate from the sensor bracket. Attached Figure Description

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0017] This utility model provides, for example Figure 1-4 The elastic detection mechanism shown includes a sensor bracket 1, an inner cavity 2 inside the sensor bracket 1, a sensor 3 fixedly inserted inside the inner cavity 2, a through hole 11 inside the sensor bracket 1, a long rod 5 movably inserted inside the through hole 11, a sensing probe 4 fitted inside the long rod 5, a base 6 fixedly installed at the lower end of the long rod 5, a compression spring 7 movably fitted on the outer ring of the long rod 5, a washer 8 fixedly installed at the end of the compression spring 7, the washer 8 movably fitted on the outer ring of the long rod 5, and a blocking nut 9 threaded on the outer ring of the long rod 5. The long rod 5 is limitedly connected to the through hole 11 by a fastening component 10 preset inside the sensor bracket 1.

[0018] The compression spring 7 and the washers 8 fixedly connected to both ends of the compression spring 7 are fitted onto the outer ring of the long rod 5. The blocking nut 9 is twisted and locked to the long rod 5, which fixes the position of the sensing probe 4 and the sensor bracket 1 that are fitted inside the long rod 5. When the sensing probe 4 is blocked and moves downward, the compression spring 7 is compressed by the downward force. The long rod 5 with the sensing probe 4 fitted inside moves down synchronously and contacts the sensor 3, causing the sensor 3 to receive a signal. This can identify the differences of some small holes between different products and solve the problem that the sensor 3 cannot identify holes that are too small.

[0019] The long rod 5 is composed of rod body 1 501 and rod body 2 502 connected together. The outer ring of rod body 1 501 is threaded with a blocking nut 9, and the lower end of rod body 2 502 is fixedly installed with a base plate 6. The outer ring diameter of the base plate 6 is larger than the outer ring diameter of rod body 2 502. Rod body 2 502 and through hole 11 are limited and slidably connected by fastening assembly 10.

[0020] The fastening assembly 10 includes a transverse groove 101 disposed inside the sensor bracket 1, and a crossbar 102 is elastically connected inside the transverse groove 101 via an elastic connector 104. The ball end 103 disposed at the end of the crossbar 102 matches the snap-fit ​​groove 107 disposed inside the rod body 502. Under the elastic force of the elastic connector 104, the crossbar 102 is pressed against the snap-fit ​​groove 107. The inner wall of the snap-fit ​​groove 107 is smooth, and the edge of the snap-fit ​​groove 107 is arc-shaped.

[0021] When the long rod 5 is pressed down (the elastic force of the elastic connector 104 is less than the elastic force of the compression spring 7), the synchronous pressing down of the locking groove 107 presses against the ball end 103, causing the ball end 103 to move into the transverse groove 101, thus not affecting the descent of the long rod 5. When the external force disappears, the compression spring 7 resets and drives the long rod 5 to reset and move upward, making it convenient for the ball end 103 to reconnect with the locking groove 107 (in the initial state, the ball end 103 and the locking groove 107 are in a matched connection state).

[0022] The fastening assembly 10 also includes a protrusion 105 fixedly installed at the end of the crossbar 102, and the protrusion 105 is slidably connected to the strip groove 106, and the strip groove 106 is connected to the transverse groove 101 to ensure that the crossbar 102 can move elastically and stably inside the transverse groove 101. The protrusion 105 is square, and the outer wall of the protrusion 105 is attached to the inner wall of the strip groove 106 to achieve a slidable connection.

[0023] This ensures that after the blocking nut 9 is turned to separate from the long rod 5, the compression spring 7 pops out and, under the elastic force of the elastic connector 104, presses against the crossbar 102 to match the locking groove 107. This prevents the long rod 5 from sliding downwards with the through hole 11 due to gravity, thus preventing the long rod 5 from falling off the through hole 11 inside the sensor bracket 1 and avoiding damage to the sensing probe 4 from falling.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
