Description

Technical Field

[0001] This utility model relates to the field of spring processing technology, and in particular to a spring positioning mechanism. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. It is a part made of elastic material that deforms under the action of external force and returns to its original shape after the external force is removed. It is also called a "spring". It is generally made of spring steel. There are many types of springs. According to their shape, the main types are helical springs, spiral springs, leaf springs, and special-shaped springs. At the same time, after the spring is produced, it needs to be stretched and oiled.

[0003] Chinese Patent Publication No. CN215656158U discloses a spring positioning mechanism, including a support plate. A rotating tube is horizontally mounted on the support plate via a bearing seat. A connecting ring is coaxially welded to one end of the rotating tube. Several expansion blocks are slidably connected to the end face of the connecting ring away from the rotating tube. The expansion blocks slide radially along the connecting ring. The inner walls of all the expansion blocks combine to form a conical cavity. The large-diameter end of the conical cavity faces the connecting ring. A moving rod is coaxially and movably arranged inside the rotating tube. One end of the moving rod is rotatably connected to a frustum head. The moving rod can move toward the connecting ring, thereby causing the side wall of the frustum head to abut against the inner wall of the expansion block, so that the expansion block slides outward radially along the connecting ring. The support plate is equipped with a first driving mechanism for driving the moving rod to move axially along the rotating tube and a second driving mechanism for driving the rotating tube to rotate.

[0004] However, the aforementioned positioning structure can only position one end of the spring when positioning it, and it cannot spread the spring to the appropriate distance for even oiling as needed. This results in uneven oiling of some parts of the spring, affecting subsequent processing and reducing the effectiveness of use. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a spring positioning mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a spring positioning mechanism, including a processing table, an assembly bracket fixedly connected to the top of the processing table, an assembly groove opened at the bottom of the assembly bracket, an assembly tooth groove opened on the inner wall of the assembly groove, two symmetrical assembly blocks movably sleeved on the outer wall of the assembly bracket, an assembly support plate fixedly connected to the top of the assembly blocks, and an assembly component connected to the bottom of the assembly blocks. Two of the assembly support plates are symmetrically connected to a fixed hollow rod on one side. One end of the fixed hollow rod is fixed and connected to a fixed outer shell. Four fixed push rods are provided through the outer wall of the fixed outer shell. Fixed abutments and fixed protrusions are fixedly connected to both ends of the fixed push rods respectively. Fixed springs are movably sleeved on the outer wall of the fixed push rods. The two ends of the fixed springs are fixedly connected to the side wall of the fixed protrusion and the inner wall of the fixed outer shell respectively. A drive assembly is connected to the other end of the fixed hollow rod. One of the fixed hollow rods has a first synchronous wheel fixedly sleeved on its outer side wall, and one of the assembly support plates has a movable component connected to its side wall to adjust the rotation of the first synchronous wheel. A coating component is provided between the front and rear sides of the processing table.

[0007] As a further description of the above technical solution: the assembly component includes an assembly housing fixedly connected to the bottom of the assembly block, an assembly self-locking motor is fixedly connected between the two sides of the inner wall of the assembly housing, and an assembly rod is fixedly connected to the output end of the assembly self-locking motor, so as to drive the assembly rod to rotate.

[0008] As a further description of the above technical solution: the end of the assembly rod penetrates the assembly housing and the assembly block and extends into the assembly groove. An assembly gear is fixedly connected to the end of the assembly rod. The assembly gear meshes with the assembly tooth groove. The assembly rod drives the assembly gear to rotate. At the same time, the assembly gear meshes with the assembly tooth groove, so that the assembly gear moves inside the assembly groove.

[0009] As a further description of the above technical solution: the driving assembly includes a self-locking motor fixedly connected to the other end of the fixed hollow rod, a driving rod fixedly connected to the output end of the self-locking motor, the end of the driving rod passing through the fixed hollow rod and extending into the interior of the fixed housing, and a driving cam fixedly connected to the end of the driving rod, thereby driving the driving rod to rotate through the self-locking motor.

[0010] As a further description of the above technical solution: the movable component includes a movable motor fixedly connected to the side wall of one of the mounting support plates. The output shaft of the movable motor passes through the mounting support plate and is fixedly connected to a second synchronous pulley. The second synchronous pulley is driven by a synchronous toothed belt meshing with the first synchronous pulley. The movable motor drives the second synchronous pulley to rotate.

[0011] As a further description of the above technical solution: the coating component includes movable grooves opened on the front and rear sides of the processing table, movable sliders are slidably connected inside the movable grooves, and movable brackets are fixedly connected between the two movable sliders. A movable cylinder is fixedly connected to the top of the movable bracket, and a movable oil nozzle is fixedly connected to the piston end of the movable cylinder through the movable bracket. The movable cylinder is used to push the movable oil nozzle to move.

[0012] As a further description of the above technical solution: multiple movable bristles are fixedly connected to the bottom of the movable oil injector, two movable motors are fixedly connected to the surface of the processing table, and a movable screw is fixedly connected to the output end of the movable motor. The end of the movable screw passes through the processing table and is rotatably connected to the inner wall of its corresponding movable groove. The outer wall of the movable screw is threadedly connected to its corresponding movable slider. The movable motors are used to drive the movable screw to rotate.

[0013] This utility model has the following beneficial effects: The drive assembly enables the self-locking motor to rotate the drive cam, which in turn applies a pushing force to the corresponding fixed protrusion. This causes the fixed protrusion to move the fixed push rod and the fixed spring along the direction of the fixed housing. The fixed push rod then moves the fixed clamping member, which then clamps the spring material at both ends. The assembly assembly enables the self-locking motor to rotate the assembly gear, which meshes with the assembly tooth groove, moving within the groove. This moves the assembly block along the direction of the assembly bracket, which in turn moves the fixed hollow rod on the assembly support plate. This causes the fixed housing on the fixed hollow rod to spread the clamped spring material to the sides to a suitable distance. The movable component allows the movable motor to drive the second synchronous pulley to rotate. The second synchronous pulley, via a synchronous toothed belt, drives the fixed hollow rod on the first synchronous pulley to rotate, as well as the fixed outer shell. The fixed outer shell then rotates, pressing against the spring material. The coating component allows the movable cylinder to push multiple movable brushes on the movable spray head to contact the spring material. Simultaneously, the movable motor drives the movable screw to rotate in both directions. The movable slider then moves along the direction on the movable screw, sliding and guiding itself within the movable groove. The movable slider also drives the movable spray head and multiple movable brushes on the movable bracket to evenly spray and coat the spring material, ensuring stable positioning at both ends of the spring material. This unfolds the spring material and evenly coats it with oil, thereby improving the performance. Attached Figure Description

[0021] Working principle: In use, first, both ends of the spring material are fitted with multiple fixed abutments 12. Then, the drive self-locking motor 14 is started. The drive self-locking motor 14 drives the drive rod 15 and drive cam 16 to rotate. At the same time, the drive cam 16 gives its corresponding fixed protrusion 13 a pushing force. Then, the fixed protrusion 13 drives the fixed push rod 11 and the fixed spring to move along the direction on the fixed housing 10. Then, the fixed push rod 11 also drives the fixed abutment 12 to move, so that the fixed abutment 12 abuts against the inside of both ends of the spring material.

[0022] Then, the self-locking assembly motor 5 on the assembly housing is started. The self-locking assembly motor 5 drives the assembly rod 6 and the assembly gear 7 to rotate. At the same time, the assembly gear 7 meshes with the assembly tooth groove 8, causing the assembly gear 7 to move inside the assembly groove. Then, the assembly housing on the self-locking assembly motor 5 drives the assembly block 3 to move along the direction on the assembly bracket 2. Then, the assembly block 3 drives the fixed hollow rod 9 on the assembly support plate 4 to move, so that the fixed housing 10 on the fixed hollow rod 9 drives the two ends of the pressed spring material to unfold to the sides to a suitable distance.

[0023] Next, the movable motor 18 on the movable component is started, which drives the second synchronous pulley 19 to rotate. Then, the second synchronous pulley 19 drives the fixed hollow rod 9 on the first synchronous pulley 17 to rotate via the synchronous toothed belt 20. Then, the fixed hollow rod 9 also drives the fixed housing 10 to rotate, and then the anti-spring material on the fixed housing 10 also rotates.

[0024] Next, the hose connector on the oil pump is fixedly installed to the movable oil nozzle 24. Then, the movable cylinder 23 is started, which pushes the movable oil nozzle 24 down to a suitable height. At the same time, the multiple movable bristles 25 on the movable oil nozzle 24 come into contact with the spring material. Then, the external oil pump is started, which drives the oil pump to spray and apply lubricating oil through the movable oil nozzle 24 on the hose.

[0025] Simultaneously, two moving motors 26 are started, which drive the moving screw 27 to rotate in the same direction. Then, the moving slider 21 moves along the direction on the moving screw 27. At the same time, the moving slider 21 is slidably installed and guided inside the moving groove. Then, the moving slider 21 also drives the moving bracket 22 to move left and right. Then, the moving bracket 22 also drives the multiple moving bristles 25 on the moving oil spray head 24 to spray and coat the spring material evenly.
