Description

Technical Field

[0001] This utility model relates to the technical field of spring detection devices, specifically an automatic spring detection device. Background Technology

[0002] As a fundamental component widely used in the mechanical field, the quality of springs directly affects the stability and safety of equipment. Traditional spring testing mainly relies on manual measurement or simple mechanical devices, which suffers from low efficiency, poor accuracy, and high labor intensity. Existing testing equipment often can only measure a single parameter (such as length or pressure), and the spring positioning is inaccurate, easily leading to deviations in test results. Therefore, there is an urgent need for an automated device that integrates positioning and testing functions to improve testing efficiency and accuracy while reducing labor costs.

[0021] like Figures 1-7 As shown, an automatic spring detection device includes a detection seat 1, a pressing part is arranged on the upper side of the detection seat 1, a plurality of limiting push blocks 2 are arranged inside the detection seat 1, and a detection cavity is formed between the plurality of push blocks. The detection cavity is used to accommodate the spring to be detected, and a detection component and a bottom ejection component are arranged at the bottom of the detection cavity. The top of the detection seat 1 is provided with a support arm 3, the middle of the support arm 3 is provided with an upper pop-out component, the upper end of the support arm 3 is bent and positioned above the detection cavity, the pressing part includes a telescopic pressure rod 4, the telescopic pressure rod 4 is connected to the support arm 3, and the extended end of the telescopic pressure rod 4 is connected to several pressure blocks 5.

[0022] The support arm 3 can be fixed to the upper part of the detection seat 1 by bolts or welding. The upper end of the support arm 3 is bent to form a horizontal fixed section, and the extended end of the telescopic pressure rod 4 is connected to the fixed section. The telescopic pressure rod 4 is an electric telescopic rod, model TD-100.

[0023] The limiting push block 2 is vertically positioned, with its bottom not exceeding the compression height of the spring under test, and its top exceeding the top of the spring under test. Multiple limiting push blocks 2 are arranged in an array, centered on the spring under test, with the limiting push blocks 2 adjacent to the spring under test but not in contact with it.

[0024] like Figure 4 As shown, the detection assembly includes a support base 6, the upper surface of which is used to support the spring to be tested, and a pressure sensor is configured on the support base 6.

[0025] The pressure sensor can be a piezoresistive pressure sensor, a resistance strain gauge pressure sensor, a capacitive pressure sensor, or a piezoelectric pressure sensor. Other detection materials, such as a silicon diaphragm, are set on the upper surface of the support base 6 so that they can make uniform and stable contact with the spring to be tested.

[0026] like Figure 6 As shown, the bottom pop-out assembly includes two connecting seats 7 and a pop-out rod 8 connected between the two connecting seats 7. The support base 6 has a receiving groove 9 in the middle, which is used to receive the pop-out rod 8. The end of the pop-out rod 8 is bent downward to form a connecting section, and the lower end of the connecting section is slidably connected to the connecting seat 7. The connecting seat 7 is arranged vertically, and a first electromagnet 10 is arranged at the bottom of the connecting seat 7. A first limiting end piece 11 is arranged at the lower end of the connecting section, and a first tension spring 12 is connected between the first limiting end piece 11 and the first electromagnet 10.

[0027] The first limiting end piece 11 is made of magnet. When the first electromagnet 10 is energized, it can magnetically attract the first limiting end piece 11, causing the ejector rod 8 to retract downwards without affecting the detection of the spring under test. After the detection is completed, the first electromagnet 10 is energized in reverse. The first electromagnet 10 and the first limiting end piece 11 have the same magnetic poles. The magnetic poles push the ejector rod 8 upwards, causing the ejector rod 8 to quickly spring upwards, thus ejecting the spring under test upwards.

[0028] like Figure 4 As shown, the upper pop-out assembly includes an auxiliary telescopic rod 19 and a pusher plate 13. The auxiliary telescopic rod 19 is connected to the support arm 3, and the pusher plate 13 is connected to the extended end of the auxiliary telescopic rod 19. The pusher plate 13 is located on the upper side of the opening of the detection cavity.

[0029] The axis of the auxiliary telescopic rod 19 is set perpendicular to the length direction of the support arm 3. When the auxiliary telescopic rod 19 is retracted, the push plate 13 is in contact with the support arm 3, which does not affect the movement of the auxiliary pressure rod and the pressure block 5.

[0030] like Figure 4 As shown, the inner wall of the detection seat 1 is recessed to form several receiving spaces, which are used to accommodate the limiting push block 2. The several limiting push blocks 2 are arranged in a circumferential array. The top of the limiting push block 2 is inclined towards the lower part of the axis of the detection seat 1 to form a guide slope. The detection seat 1 is equipped with a limiting push rod 14 on the outside. The extended end of the limiting push rod 14 is connected to the limiting push block 2.

[0031] The limiting push block 2 can move radially along the detection seat 1. When the limiting push block 2 moves, the diameter of the detection cavity changes, which can accommodate different springs to be detected.

[0032] like Figure 4 As shown, an auxiliary guide plate 15 is provided on the top of the limiting push block 2, and a vibration motor 16 is arranged on the upper part of the limiting push block 2. The vibration motor is connected to the auxiliary guide plate 15.

[0033] The vibration motor 16 is used to make the limit push block 2 vibrate slightly to prevent the spring to be tested from getting stuck on the upper end of the limit push block 2 when feeding.

[0034] like Figure 4 As shown, a guide rod 17 is connected to the back of the push plate 13, and a second limiting end piece 18 is connected to the outer end of the guide rod 17. A second electromagnet 20 is disposed inside the auxiliary telescopic rod 19, and a second tension spring 21 is connected between the second electromagnet 20 and the second limiting end piece 18.

[0035] The operating principle of the auxiliary telescopic rod 19 is the same as that of the connecting seat 7. The push plate 13 is ejected outward by magnetic force. When the spring to be tested is ejected from the inside of the testing chamber, it moves to one side of the push plate 13, and then the push plate 13 pushes the spring outward to complete the unloading.

[0036] like Figure 4 As shown, the number of pressure blocks 5 is the same as the number of limiting push blocks 2, and in the top view, the pressure blocks 5 and the limiting push blocks 2 are arranged alternately.

[0037] The number of pressure blocks 5 is at least 3, and multiple pressure blocks 5 are arranged in an array around the axis of the telescopic pressure rod 4.

[0038] In practical use, this device Place the spring to be tested into the testing chamber. The limiting push block 2 moves toward the spring to be tested under the drive of the limiting push rod 14. After automatically clamping the spring, it loosens outward by 1-2mm. The vibration motor 16 assists in centering. During the feeding process, the vibrating motor 16 always runs to prevent the spring to be tested from getting stuck on the upper end of the limit push block 2.

[0039] The telescopic pressure rod 4 drives the pressure block 5 to press down. The pressure sensor collects the spring compression data and, combined with the pressing height of the telescopic pressure rod 4, determines whether the spring is qualified.

[0040] When the bottom pop-out component is activated, the pop-out rod 8 pops out upward, causing the spring to pop out upward along the detection cavity. When the upper pop-out component is activated, the spring is pushed laterally to the recycling box by the pusher plate 13. After the inspection is completed, all components are returned to their initial positions, awaiting the next cycle.

[0041] An infrared ranging sensor or other sensor for measuring the compression height of the spring to be tested can also be installed inside the detection base 1, and a controller can be set up to coordinate the actions of the electromagnet, sensor and other structures.

[0042] The above-described specific embodiments are merely specific examples of this utility model. The patent protection scope of this utility model includes, but is not limited to, the product form and style of the above-described specific embodiments. Any automatic spring detection device that conforms to the claims of this utility model and any appropriate changes or modifications made to it by a person skilled in the art should fall within the patent protection scope of this utility model.
