Description

Technical Field

[0001] This utility model relates to the field of spring production equipment, specifically to a clamping fixture for spring testing. Background Technology

[0002] Springs are mechanical parts that utilize the elastic deformation of metals. They are mainly divided into compression springs, tension springs, torsion springs, and clockwork springs. Their core function is to store energy through deformation. They are widely used in automobiles, home appliances, medical devices, and other fields. Larger springs are commonly used in heavy machinery, military equipment, aerospace, and energy equipment. After the production of large-size springs is completed, the surface quality of the springs needs to be monitored. During the inspection process, clamping fixtures are required to hold the springs. Existing clamping fixtures are dedicated to specific machines and have poor adaptability. Therefore, it is necessary to design a clamping fixture that can adapt to the inspection of springs of different sizes and lengths. Utility Model Content

[0003] The purpose of this invention is to provide a clamping fixture for spring testing, which has the advantages of being able to adapt to springs of different sizes and lengths and having strong adaptability.

[0004] The technical solution adopted is as follows: A clamping fixture for spring testing includes a base and a lifting platform. The base has two upright plates. A slider is slidably mounted on the inner side of one of the upright plates. A first support shaft is rotatably mounted on the inner side of the slider. A second support shaft is rotatably mounted on the opposite upright plate. Both the first and second support shafts have conical portions at their ends. A first telescopic mechanism is provided between the upright plates and the slider. The lifting platform is located between the two conical portions. A driving mechanism is provided on the base, which drives the first and second support shafts to rotate at the same speed and in the same direction.

[0005] Preferably, the lifting platform is a manual hydraulic lift.

[0006] Preferably, the upper surface of the lifting platform is provided with a U-shaped groove.

[0007] Preferably, the first telescopic mechanism includes a manual hydraulic telescopic cylinder and several guide shafts. The guide shafts are fixedly connected to the slider and slidably connected to the corresponding vertical plate. The two ends of the manual hydraulic telescopic cylinder are fixedly connected to the vertical plate and the slider.

[0008] Preferably, the driving mechanism includes a rotating handle and a transmission mechanism. The rotating handle is coaxially and fixedly connected to the second support shaft. Both the column and the base are provided with cavities. The transmission mechanism is set in the cavity. The transmission mechanism includes two vertical first transmission shafts and one horizontal second transmission shaft. The first transmission shafts are connected to the second transmission shafts by bevel gears. The first support shaft and the second support shaft are connected to the corresponding first transmission shafts by bevel gears.

[0009] Preferably, the cavity is provided with lubricating grease.

[0010] Compared to existing technologies, the advantages are: This invention uses a lifting platform to raise the spring to a height corresponding to the two conical parts, controls the movement of the slider to fix the spring by inserting the two conical parts into the two ends of the spring, and drives the spring to rotate to detect the spring. It can adapt to springs of different lengths and inner diameters and has strong adaptability. Attached Figure Description

[0013] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 3 As shown: Example 1: A clamping fixture for spring detection includes a base 1 and a lifting platform 2. Two upright plates 3 are provided on the base 1. A slider 4 is slidably provided on the inner side of one of the upright plates 3. The slider 4 is located between the two upright plates 3. A first support shaft 5 is rotatably provided on the inner side of the slider 4. A second support shaft 6 is rotatably provided on the opposite upright plate 3. Both the first support shaft 5 and the second support shaft 6 are provided with a conical part 7 at their ends. The first support shaft 5 and the second support shaft 6 are coaxially arranged.

[0014] A first telescopic mechanism 8 is provided between the upright plate 3 and the slider 4. The first telescopic mechanism 8 extends and retracts to control the slider 4 to move between the two upright plates 3. The lifting platform 2 is provided between the two conical parts 7. The lifting platform 2 is used to lift and lower the spring. A drive mechanism is provided on the base 1. The drive mechanism drives the first support shaft 5 and the second support shaft 6 to rotate at the same speed and in the same direction.

[0015] During operation, the spring is placed on the lifting platform 2, and the spring is raised to the height corresponding to the two conical parts 7 by the lifting platform 2. The slider 4 is controlled to move so that the two conical parts 7 are inserted into the two ends of the spring to fix the spring. Then the lifting platform 2 descends and disengages from the spring, and the drive mechanism drives the spring to rotate so as to detect the spring.

[0016] Example 2: A clamping fixture for spring detection includes a base 1 and a lifting platform 2. Two upright plates 3 are provided on the base 1. A slider 4 is slidably provided on the inner side of one of the upright plates 3. The slider 4 is located between the two upright plates 3. A first support shaft 5 is rotatably provided on the inner side of the slider 4. A second support shaft 6 is rotatably provided on the opposite upright plate 3. Both the first support shaft 5 and the second support shaft 6 are provided with a conical part 7 at their ends. The first support shaft 5 and the second support shaft 6 are coaxially arranged.

[0017] A first telescopic mechanism 8 is provided between the upright plate 3 and the slider 4. The first telescopic mechanism 8 includes a manual hydraulic telescopic cylinder and several guide shafts. The guide shafts are fixedly connected to the slider 4 and slidably connected to the corresponding upright plate 3. The two ends of the manual hydraulic telescopic cylinder are fixedly connected to the upright plate 3 and the slider 4. The first telescopic mechanism 8 extends and retracts to control the slider 4 to move between the two upright plates 3. The lifting platform 2 is provided between the two conical parts 7. The lifting platform 2 is a manual hydraulic lift. The lifting platform 2 is used to lift and lower the spring. The upper end face of the lifting platform 2 is provided with a U-shaped groove 9. The spring is placed in the U-shaped groove to limit the spring and prevent it from rolling off.

[0018] A drive mechanism is provided on the base 1. The drive mechanism drives the first support shaft 5 and the second support shaft 6 to rotate at the same speed and in the same direction. The drive mechanism includes a rotating handle 10 and a transmission mechanism. The rotating handle 10 is coaxially and fixedly connected to the second support shaft 6. A cavity 14 is provided in both the column and the base 1. The transmission mechanism is located in the cavity 14. The transmission mechanism includes two vertical first transmission shafts 11 and one horizontal second transmission shaft 12. The first transmission shafts 11 are connected to the second transmission shafts 12 by bevel gears 13. The first support shaft 5 and the second support shaft 6 are connected to the corresponding first transmission shafts 11 by bevel gears 13. Lubricating grease is provided in the cavity 14 to make the meshing of the bevel gears 13 smoother.

[0019] The working principle is as follows: When monitoring the spring, the spring is placed on the lifting platform 2. The lifting platform 2 lifts the spring to the height corresponding to the two conical parts 7. The slider 4 is moved by extending and retracting the manual hydraulic telescopic cylinder, so that the two conical parts 7 are inserted into the two ends of the spring to fix the spring. Then the lifting platform 2 descends and disengages from the spring. The second support shaft 6 is driven to rotate by turning the handle 10. The meshing of the first transmission shaft 11 and the second transmission shaft 12 realizes that the first support shaft 5 and the second support shaft 6 rotate at the same speed and in the same direction, thereby realizing the detection of the spring.
