Description

Technical Field

[0001] This utility model relates to the field of compression spring processing technology, specifically a compression spring perpendicularity correction and fixing device. Background Technology

[0002] Compression springs, as key components widely used in the industrial field, play a crucial role, much like the "elastic heart" of a mechanical system. From automotive suspension systems, where their damping properties effectively reduce the impact of uneven road surfaces and create a comfortable driving experience; to sophisticated electronic devices, where they maintain close contact between components and ensure stable signal transmission; and to large mechanical equipment, where they balance pressure and control motion, compression springs are ubiquitous. Their performance directly affects the stable operation and efficiency of the entire system. Among the many performance indicators of compression springs, perpendicularity is considered one of the core elements. Ideally, a spring should maintain a perfect perpendicular relationship with the horizontal plane when naturally standing.

[0003] When fixing compression springs for perpendicularity, traditional manual methods rely heavily on the experience and feel of workers. The accuracy depends entirely on individual skill levels, resulting in extremely low efficiency, making it difficult to meet the demands of large-scale industrial production. Furthermore, inconsistent accuracy leads to inconsistent product quality. While some highly automated calibration equipment improves efficiency, it often has a complex structure, integrating numerous electronic components and control systems. This significantly increases equipment purchase costs and maintenance difficulty. In case of malfunction, repairs are lengthy and costly, and the equipment is susceptible to electromagnetic interference, causing fluctuations in calibration accuracy and greatly reducing its applicability. Both manual and automated methods only position the bottom of the compression spring. However, when fixing larger compression springs, a high tilt angle can exert significant pressure on the fixing device, potentially damaging it and reducing the fixing effect.

[0004] To address this, a compression spring verticality correction and fixing device is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a compression spring verticality correction and fixing device to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A compression spring verticality correction and fixing device includes a fixing frame and a support plate, and further includes a servo motor, a connecting mechanism, a connecting plate, a secondary gear, a correction mechanism, and a top block. The servo motor is fixedly installed at the bottom end of the support plate. The connecting mechanism is connected to the servo motor. The connecting plate and the secondary gear are both connected to the connecting mechanism. The correction mechanism is connected to the secondary gear. The top block is connected to the correction mechanism. When the servo motor is started, the connecting mechanism controls the extension of the connecting plate to fit against the inner wall of the compression spring. When the compression spring tilts and presses against the connecting plate, the secondary gear runs and drives the top block to rise through the correction mechanism to correct the compression spring.

[0007] Preferably, the connecting mechanism includes a main gear, a connecting rack, a mounting base, a vertical rod, a driving rack, a limiting block, and a pressure plate. The main gear is fixedly installed at the output end of the servo motor, the connecting rack meshes with the main gear, the mounting base is fixedly installed at the top of the connecting rack, the vertical rod is installed at the top of the mounting base, the driving rack is slidably connected to the vertical rod, the limiting block is fixedly installed at one end of the connecting rack, and the pressure plate is fixedly installed at one end of the driving rack.

[0008] Preferably, the connecting racks are arranged in three sets around the axis of the main gear, and the support plate has a rotating groove and a moving groove inside, which are connected. The main gear is rotatably installed in the rotating groove, and the connecting racks are slidably installed in the moving groove.

[0009] Preferably, one end of the vertical rod is provided with an inclined portion, which is flush with one end of the pressure plate, and a groove is provided in the inclined portion, which is engaged with the pressure plate.

[0010] Preferably, the connecting plate includes a flexible part and a rigid part, the flexible part is fixedly installed at one end of the vertical rod, and the rigid part corresponds to the pressure plate.

[0011] Preferably, a limiting groove is formed inside the vertical rod, and the limiting block cooperates with the limiting groove.

[0012] Preferably, the calibration mechanism includes a screw, a movable rod, a fixed rod, and a base. The screw is fixedly installed at the bottom end of the secondary gear. The vertical rod is threadedly connected to the screw. The movable rod is fixedly installed at the bottom end of the vertical rod. The fixed rod is slidably connected to the movable rod. The base is fixedly installed at the bottom end of the fixed rod and at the top end of the mounting base.

[0013] Preferably, the movable rod and the fixed rod are each arranged in two sets symmetrically with the fixed rod as the center.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The three sets of vertical rods are controlled by servo motors to extend outwards to fit against the inner wall of the compression spring, thereby positioning the compression spring. While positioning the compression spring, pressure is applied to the connecting plate. Under the action of pressure, the vertical rods and the top block are controlled to rise, thereby correcting the bottom end of the compression spring and increasing the fixed height of the compression spring. This ensures that the compression spring remains stable during correction and guarantees the smooth progress of the compression spring correction. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the embodiments described below are only some embodiments of the present utility model, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0018] Reference Figures 1 to 6A compression spring verticality correction and fixing device includes a fixing frame 1 and a support plate 2. Two support plates 2 are symmetrically arranged around the center line of the fixing frame 1. A correction device is installed at the bottom of the upper support plate 2, and the center point of the correction device coincides with the center point of the support plate 2. Through the above arrangement, the verticality of the fixed compression spring can be easily corrected. An adjustment device is provided inside the fixing frame 1. Through the setting of the adjustment device, a servo motor 3, a connecting mechanism 4, a connecting plate 5, a secondary gear 6, a correction mechanism 7, and a top block 8 are also included. The servo motor 3 is fixedly installed at the bottom of the support plate 2. The connecting mechanism 4 is connected to the servo motor 3. The connecting plate 5 and the secondary gear 6 are both connected to the connecting mechanism 4. The correction mechanism 7 is connected to the secondary gear 6. The top block 8 is connected to the correction mechanism 7. When the servo motor 3 is started, the connecting mechanism 4 controls the extension of the connecting plate 5 to fit against the inner wall of the compression spring. When the compression spring tilts and squeezes the connecting plate 5, the secondary gear 6 runs and drives the top block 8 to rise through the correction mechanism 7 to correct the compression spring.

[0019] As one embodiment of this utility model, refer to Figures 3 to 6The connecting mechanism 4 includes a main gear 41, a connecting rack 42, a mounting base 43, a vertical rod 44, a driving rack 45, a limiting block 46, and a pressure plate 47. The main gear 41 is fixedly mounted on the output end of the servo motor 3. The connecting rack 42 meshes with the main gear 41. The mounting base 43 is fixedly mounted on the top of the connecting rack 42. The vertical rod 44 is mounted on the top of the mounting base 43. The driving rack 45 is slidably connected to the vertical rod 44. The limiting block 46 is fixedly mounted on one end of the connecting rack 42. The pressure plate 47 is fixedly mounted on one end of the driving rack 45. The connecting rack 42 is connected to the main gear 41. The support plate 2 has three sets of circumferentially arranged shafts. The support plate 2 has a rotating groove 48 and a moving groove 49 inside, which are connected. The main gear 41 is rotatably mounted in the rotating groove 48, providing space for its rotation. The connecting rack 42 is slidably mounted in the moving groove 49, providing space for its movement. One end of the vertical rod 44 has an inclined portion 410, which is flush with one end of the pressure plate 47. This arrangement allows for the adjustment of the inclined... The compression spring cooperates with the inclined part 410, which has a groove 411. The pressure plate 47 cooperates with the groove 411. The groove 411 allows the pressure plate 47 to be retracted when it is compressed, thereby increasing the travel distance of the drive rack 45. This allows the screw 71 to rotate more times, increasing the height of the vertical rod 44. The connecting plate 5 includes a flexible part 51 and a rigid part 52. The flexible part 51 is fixedly installed at one end of the vertical rod 44. The flexible part 51 allows the connecting plate 5 to be controlled when it is subjected to the pressure of the compression spring. Deformation occurs to prevent damage to the connecting plate 5. The rigid part 52 corresponds to the pressure plate 47. The rigid part 52 enables the connecting plate 5 to withstand the pressure of the compression spring, preventing damage to the rigid part 52. A limiting groove 412 is provided inside the vertical rod 44. The limiting block 46 cooperates with the limiting groove 412. The limiting groove 412 provides space for the movement of the limiting block 46. The limiting block 46 and the limiting groove 412 limit the movement path of the connecting rack 42 when it moves, preventing the connecting rack 42 from deflecting when it moves.

[0020] As one embodiment of this utility model, refer to Figure 5 and Figure 6The correction mechanism 7 includes a screw 71, a movable rod 72, a fixed rod 73, and a base 74. The screw 71 is fixedly installed at the bottom end of the secondary gear 6. The vertical rod 44 is threadedly connected to the screw 71. The movable rod 72 is fixedly installed at the bottom end of the vertical rod 44. The fixed rod 73 is slidably connected to the movable rod 72. The base 74 is fixedly installed at the bottom end of the fixed rod 73 and at the top end of the mounting base 43. The movable rod 72 and the fixed rod 73 are symmetrically arranged in two sets around the fixed rod 73. Through the above arrangement, the vertical rod 44 can maintain the balance at both ends when it is raised and lowered, and can avoid the vertical rod 44 from tilting when it is under force, so that the vertical rod 44 can stably support the compression spring.

[0021] Working principle: In use, the user places the compression spring on the support plate 2 below and fits it on the outside of the vertical rod 44. Then, the servo motor 3 is started. The servo motor 3 drives the main gear 41 to rotate. When the main gear 41 rotates, it drives the three connecting racks 42 to move synchronously. When the connecting racks 42 move, they drive the mounting base 43 to move synchronously. When the mounting base 43 moves, it drives the vertical rod 44 to move. When the vertical rod 44 moves, it drives the connecting plate 5 to move synchronously and fit against the inner wall of the compression spring. Once the compression spring tilts, it will squeeze the connecting plate 5 on the tilted side. The pressure will push the connecting plate 5 under the action of pressure. When the connecting plate 5 is pushed, it can drive the bearing plate 47 to move synchronously. When the bearing plate 47 moves, it can drive the secondary gear 6 to rotate through the drive rack 45. When the secondary gear 6 rotates, it can drive the screw 71 to rotate. When the screw 71 rotates, it can drive the vertical rod 44 to rise. When the vertical rod 44 rises, it can drive the movable rod 72 to move within the fixed rod 73, thereby driving the top block 8 to rise. When the top block 8 rises, it can lift the bottom end of the compression spring upward to correct the bottom end of the compression spring, thereby making the bottom end of the compression spring more stable.

The appended claims and their equivalents define the scope of this utility model.
