Description

Technical Field

[0001] This utility model relates to the technical field of crown spring production, and in particular to a gripping mechanism for picking up and narrowing the crown spring material. Background Technology

[0002] During the sleeve production process, the crown spring needs to be placed inside the sleeve. In order to ensure that the crown spring can deform radially, a forming groove is formed on the crown spring along the length direction. When the crown spring is placed into the sleeve, the radial dimension of the crown spring needs to be reduced to better fit into the inside of the sleeve and form an elastic structure. When the crown spring is radially compressed, the two sides of the forming groove are easily squeezed and damaged. If irreversible deformation occurs, the sleeve will be unusable.

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 7 As shown in this embodiment, a gripping mechanism for a crown spring with a narrowed opening includes a flipping structure and a narrowing structure. The flipping structure includes a flipping stand 1, on which a flipping cylinder 2 is mounted. A steering module 3 is mounted on the drive end of the flipping cylinder 2. A temporary storage cavity 4 is provided at the outer end of the steering module 3. A push rod 5 is installed inside the steering module 3, and one end of the push rod 5 is inserted into the temporary storage cavity 4. The narrowing structure includes a material-grabbing bracket 6, on which a horizontal material-grabbing part and a vertical material-grabbing part are provided. The vertical material-grabbing part is installed on the horizontal material-grabbing part. On the drive end, a pneumatic gripper 7 is provided on the vertical material handling part. One end of the pneumatic gripper 7 is connected to a first mounting rod 8. A first spring 9 and a first groove 10 are installed on the first mounting rod 8. A first spring block 11 is connected to the first spring 9. The other end of the pneumatic gripper 7 is connected to a second mounting rod 12. A second spring 13, a second groove 14 and a swing rod 15 are installed on the second mounting rod 12. A second spring block 16 is connected to the second spring 13. One end of the swing rod 15 is connected to the second spring block 16. The other end of the swing rod 15 is connected to an inner push rod 17.

[0027] The front equipment moves the crown spring 34 into the temporary storage cavity 4. The tilting cylinder 2 controls the steering module 3 to rotate 90°, causing the crown spring 34 to change from a horizontal to an upward vertical position. Then, the push rod 5 lifts the crown spring 34 out of the temporary storage cavity 4. The horizontal and vertical material picking parts on the material picking bracket 6 simultaneously control the pneumatic gripper 7 to align with the crown spring 34. The pneumatic gripper 7 controls the first mounting rod 8 and the second mounting rod 12 to move from both sides of the crown spring 34 towards the middle. First, the inner push rod 17 will contact one side of the forming groove 35 in the crown spring 34, causing it to be recessed inward a little distance, so that the two sides of the forming groove 35 can be staggered and wound. Under the action of the swing rod 15, the second spring block 16 is extended by the force of the second spring 13. The first mounting rod 8 and the second mounting rod As the process continues, the first spring block 11 pushes the second spring block 16 outward, and the second spring 13 begins to contract. At this time, the first groove 10 and the second groove 14 begin to clamp the outer side of the crown spring 34, causing the crown spring 34 to shrink in size. Then, the first spring 9 also begins to contract, and the first groove 10 and the second groove 14 further clamp the crown spring 34. At this time, the inner push rod 17 contacts the inner side of the first mounting rod 8. The inner push rod 17 is restricted in position after being squeezed. Under the action of the swing rod 15, the second spring block 16 extends and pushes the first spring block 11 inward. The first spring 9 begins to contract. When the first spring 9 contracts to the bottom, the first groove 10 and the second groove 14 complete the radial shrinkage of the crown spring 34, making it easy to put the current crown spring 34 into the sleeve.

[0028] An ejector cylinder 18 is installed below the steering module 3. The drive end of the ejector cylinder 18 is connected to the outer end of the ejector rod 5. A vertical plate 19 is installed in the temporary storage cavity 4. A limit strip 20 is fixed in the middle of the steering module 3. A limit groove 21 is provided in the middle of the ejector rod 5 along the length direction. The limit strip 20 passes through the limit groove 21.

[0029] The ejector cylinder 18 controls the ejector rod 5 to push the crown spring 34 to the constricted structure, and uses the limit bar 20 to limit the position of the ejection.

[0030] The transverse material handling section includes a transverse cylinder 22, a transverse slide rail 23, and a transverse support 24. The transverse slide rail 23 is fixed on the material handling bracket 6, the transverse cylinder 22 is fixed on one side of the material handling bracket 6, the drive end of the transverse cylinder 22 is connected to the transverse support 24, the lower end of the transverse support 24 slides on the transverse slide rail 23, and the vertical material handling section is connected to the transverse support 24.

[0031] During the lateral movement, the lateral movement cylinder 22 controls the lateral movement support 24 to drive the vertical material picking part to move laterally, specifically by sliding on the lateral movement slide rail 23.

[0032] The vertical moving material handling part includes a vertical moving cylinder 25 and a material handling component 26. The vertical moving cylinder 25 is fixed on the horizontal moving support 24. The drive end of the vertical moving cylinder 25 is connected to a guide shaft 27. The guide shaft 27 passes through the horizontal moving support 24 and is connected to the material handling component 26.

[0033] During longitudinal movement, the vertical movement cylinder 25 controls the material handling assembly 26 to move longitudinally, and the direction of movement is ensured by the guidance of the guide shaft 27.

[0034] The material handling assembly 26 is equipped with a mandrel cylinder 28. The driving end of the mandrel cylinder 28 is connected to a mandrel slider 29. A movable mandrel 30 is fixed at the front end of the mandrel slider 29. A limit stop bar 31 is provided on one side of the material handling assembly 26. The front end of the limit stop bar 31 is located in the vertical moving groove 32 on one side of the mandrel slider 29.

[0035] Before the radial dimension of the crown spring 34 is reduced, the mandrel cylinder 28 controls the mandrel slider 29 to move downward, so that the movable mandrel 30 is inserted into the crown spring 34 from top to bottom. The vertical movement is limited by the limit stop 31 blocking the vertical movement groove 32. When the movable mandrel 30 is inside the crown spring 34, it can be ensured that the reduction dimension is not too large, and the crown spring 34 can spring back to its original shape in the sleeve.

[0036] An auxiliary cylinder 33 is mounted on the outer end of the first mounting rod 8, and the drive end of the auxiliary cylinder 33 is fixed to the outer end of the second mounting rod 12.

[0037] The crown spring 34 shrinks in size, and the force on both sides is uneven under the action of the pneumatic gripper 7. To ensure uniform force, an auxiliary cylinder 33 is added to synchronously control the opening and closing between the first mounting rod 8 and the second mounting rod 12.

[0038] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
