Description

Technical Field

[0001] This invention relates to edge-rolling technology, and more particularly to an edge-rolling machine for satellite antennas. Background Technology

[0002] A satellite antenna is a parabolic metal surface responsible for reflecting satellite signals to the feedhorn and LNB located at the focal point. The function of a satellite antenna is to collect weak signals from satellites and remove as much noise as possible. Most antennas are parabolic, while some multifocal antennas are a combination of spherical and parabolic surfaces. Satellite signals are concentrated at the focal point after reflection by the parabolic antenna. During the manufacturing process, a flat disc needs to be edged and then rolled into a parabolic shape. This edge rolling requires a rotatable winding head. Currently, the winding heads are directly fixed with bolts, which is inconvenient for quick replacement based on the actual edge of the satellite antenna being rolled. Therefore, a winding machine is needed. Summary of the Invention

The mounting base is disposed on the arc-shaped track, and the cylinder is disposed on the mounting base. The mounting base also has a slide rail with a slide block mounted on it. The cylinder is connected to the slide block.

[0009] A crimping assembly disposed on the slide block, the crimping assembly comprising:

[0010] A fixing base has a hollowed-out center forming a fixing chamber. An opening at the top of the fixing base communicates with the fixing chamber. One end of the fixing base has a mounting hole and a through hole, while the other end has a rotating hole. The mounting hole communicates with the fixing chamber through the through hole, and the rotating hole also communicates with the fixing chamber.

[0012] A locking member is installed inside the fixed chamber. The locking member is inserted into the opening, keeping its lower end positioned within the fixed chamber and in contact with the retaining member. When the locking member slides within the opening toward the mounting hole, it pushes the limiting portion downwards, reducing the height of the limiting area.

[0013] And a take-up head for curling the edge of a workpiece, one end of the take-up head is provided with a rotating shaft, the rotating shaft is provided with a bearing, the bearing is provided in a mounting hole, and the rotating shaft passes through a through hole and a limiting area and is placed in the rotating hole.

[0014] In this invention, the length of the opening is greater than the length of the locking element.

[0015] In this invention, the fixing part consists of a symmetrically arranged fixing part, a raising part, an inclined part, and a deformable part, and the connecting part is located on the raising part.

[0016] In this invention, the deformable part is provided with a through hole, and a limiting protrusion that is raised upward is provided in the through hole, and the limiting protrusion extends into the limiting area.

[0017] In this invention, the limiting protrusion is provided with a guide slope and a vertical surface, the guide slope facing one end of the mounting hole and the vertical surface facing one end of the rotating hole.

[0018] In this invention, the limiting part is composed of a mounting part, an elastic arm, an arc-shaped arm, and a pressing arm. The arc-shaped arms are symmetrically arranged, and a limiting opening is formed between the arc-shaped arms. The elastic arm is inclined, and the width of the elastic arm is greater than the width of the mounting part.

[0019] In this invention, the pressing arm is provided with a limiting arm that extends into the elastic arm, so that when the pressing arm is subjected to an external force, the limiting arm remains in contact with the elastic arm.

Detailed Implementation

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0039] like Figures 1 to 13 As shown, this invention, a crimping machine for satellite antennas, includes a support plate 1, a pressure plate 2, a drive assembly 3, and a crimping assembly 4. A motor can be installed at the lower end of the support plate 1. The motor drives the support plate 1 to rotate, and the workpiece 5 to be crimped is placed on the support plate 1. The diameter of the workpiece 5 is larger than the diameter of the support plate 1. The pressure plate 2 is used to hold the workpiece 5 stationary, and when applying pressure to the support plate 1, the pressure plate 2 can rotate along with the support plate 1. The pressure plate 2 is located above the workpiece 5, and its diameter is smaller than the diameter of the workpiece 5. The drive assembly 3 is used to move the crimping assembly 4, allowing for changes in the forward / backward movement and angle of the crimping assembly 4, facilitating the crimping of the workpiece 5 to different angles.

[0040] The drive assembly 3 for edge curling of workpiece 5 includes an arc-shaped track 6, a mounting base 7, and a cylinder 8. The mounting base 7 is mounted on the arc-shaped track 6, and the cylinder 8 is mounted on the mounting base 7. The mounting base 7 also has a slide rail 9, on which a slide block 10 is mounted. The cylinder 8 is connected to the slide block 10. The arc-shaped track 6 can utilize existing technology and will not be elaborated upon here. The mounting base 7 is designed to move along the arc-shaped track 6, allowing the edge curling head to perform circular motion around the centerline of the arc-shaped track 6. This enables the movement of the edge curling assembly 4, ensuring that the edge of workpiece 5 can be curled at different angles according to actual needs.

[0041] The edge-rolling assembly 4 is mounted on the slide 10. The edge-rolling assembly 4 includes a fixed base 11, a retainer 12, a locking member 13, and a take-up head 14. The retainer 12 is installed in the middle of the fixed base 11, while the lower end of the locking member 13 is installed inside the fixed base 11, applying pressure to the retainer 12 and causing the limiting portion 15 to deform. The take-up head 14 is mounted in the middle of the retainer 12 via a rotating shaft 16. This not only limits its position in the middle of the retainer 12, preventing it from falling off during take-up, but also ensures that the rotating shaft 16 rotates around the centerline of the workpiece 5 within the middle of the retainer 12.

[0042] The fixing base 11 has a hollowed-out center to form a fixing chamber 17, and the retaining member 12 is installed inside the fixing chamber 17. The fixing base 11 is mounted on the slide 10. The upper end of the fixing base 11 has an opening 18, the length of which is greater than the length of the locking member 13, ensuring that the locking member 13 can slide within the opening 18 to press the limiting portion 15 on the retaining member 12, thereby reducing the limiting area 19. The opening 18 communicates with the fixing chamber 17. One end of the fixing base 11 has a mounting hole 20 and a through hole 21, and the other end has a rotating hole 22. The mounting hole 20 communicates with the fixing chamber 17 through the through hole 21, and the rotating hole 22 communicates with the fixing chamber 17.

[0043] The retainer 12 consists of a fixed part 23 and a limiting part 15. The fixed part 23 and the limiting part 15 are connected by symmetrically arranged connecting parts 24. A movable opening 25 is formed in the middle of the symmetrically arranged connecting parts 24. The rotating shaft 16 passes through the movable opening 25 and is limited in the limiting area 19.

[0044] The limiting part 15 is located at the upper end of the fixing part 23, and the retaining member 12 is installed from the bottom of the fixing base 11 into the fixing chamber 17, forming a limiting area 19 between the fixing part 23 and the limiting part 15.

[0045] The fixing part 23 consists of a symmetrically arranged fixing part 26, a raising part 27, an inclined part 28, and a deformable part 29, with the connecting part 24 located on the raising part 27. The raising part 27 is used to make the deformable part 29 have a certain elasticity, so that the inclined part 28 can be subjected to the pressure of the deformable part 29, thereby causing the deformable part 29 to deform slightly downward, so that the limiting protrusion 30 can be placed in the locking port 31.

[0046] A through hole 32 is provided on the deformable part 29, and a limiting protrusion 30 that is raised upward is provided inside the through hole 32. The limiting protrusion 30 extends into the limiting area 19. The limiting protrusion 30 is provided with a guide slope 33 and a vertical surface 34. The guide slope 33 faces one end of the mounting hole 20, and the vertical surface 34 faces one end of the rotating hole 22.

[0047] The limiting part 15 consists of a mounting part 35, an elastic arm 36, an arc-shaped arm 37, and a pressing arm 38. The arc-shaped arms 37 are symmetrically arranged, and a limiting opening 39 is formed between the arc-shaped arms 37. The limiting opening 39 can be used to open the elastic arm 36. Figure 13 As shown, when a rod 40 is inserted at an angle through the opening 18, and the lower end of the rod 40 is kept within the limiting opening 39, the lower end of the rod 40 is in contact with the linear a of the first wall surface 41 and the linear b of the second wall surface 42, while the middle of the rod 40 is in contact with the linear c of the opening 18. When the upper end of the rod 40 is pressed down, the pressing arm 38 can be tilted upwards using the linear c as a fulcrum. Then, the lower end of the elastic arm 36 is lifted by the arc arm 37, thereby allowing the second wall surface 42 to disengage from the blocking surface 43, and the rotating shaft 16 to be removed from the limiting area 19.

[0048] Although the locking port 31 is no longer restricted by the second wall surface 42, it is still restricted by the limiting protrusion 30. Therefore, it is only necessary to press the limiting protrusion 30 down to keep it also from the locking port 31. The width of the limiting protrusion 30 is greater than the diameter of the rotating shaft 16.

[0049] The elastic arm 36 is inclined, and its width is greater than that of the mounting portion 35. Since the arc-shaped arm 37 is connected to the elastic arm 36, the widths of the arc-shaped arm 37, the pressing arm 38, and the limiting arm 44 are equal to the width of the elastic arm 36. This facilitates contact between the locking arm 49 and the arc-shaped arm 37, thereby limiting the position of the locking member 13 and preventing it from disengaging from the opening 18. A passage area 53 is formed between the locking arms 49 for the rotating shaft 16 to pass through.

[0050] Additionally, a limiting arm 44 extending towards the elastic arm 36 is provided on the lower pressing arm 38. When the lower pressing arm 38 is subjected to external force, the limiting arm 44 remains in contact with the elastic arm 36. The limiting port 39 is provided with a first wall surface 41 and a second wall surface 42. The first wall surface 41 is perpendicular to the lower pressing arm 38, and the second wall surface 42 is located at the connection between the elastic arm 36 and the arc-shaped arm 37 and is inclined.

[0051] The bottom of the locking member 13 is provided with a pushing protrusion 45. One end of the pushing protrusion 45 is provided with a first pushing slope 46, and the other end is provided with a second pushing slope 47. An arc-shaped surface 48 is formed between the first pushing slope 46 and the second pushing slope 47. The bottom of the locking member 13 is also provided with symmetrically arranged locking arms 49. The locking arms 49 are provided with locking slopes 50. When the locking member 13 slides toward the mounting hole 20, the arc-shaped surface 48 pushes the pressing arm 38 down, and keeps the locking slope 50 in contact with the arc-shaped arm 37.

[0052] like Figure 12 As shown, the locking member 13 is close to the rotating hole 22 at this time, and the pressing arm 38 will be lifted upward under the elastic force of the arc arm 37 (not shown in the figure). Through the contact between the pressing arm 38 and the arc surface 48, a certain gap will be formed between the limiting arm 44 and the elastic arm 36. When the locking member 13 is pushed to slide towards the through hole 21, the arc surface 48 can be kept sliding on the pressing arm 38, so that the gap disappears, the limiting arm 44 contacts the elastic arm 36, and when it continues to slide, the elastic arm 36 can be pressed down into the locking port 31, so that the arc surface 48 passes through the connection point d of the limiting arm 44 and the pressing arm 38, and the locking member 13 locks and fixes the limiting part 15, keeping the limiting part 15 in a fixed position for the rotating shaft 16.

[0053] The locking member 13 is inserted into the opening 18, keeping its lower end within the fixing chamber 17 and in contact with the retainer 12. As the locking member 13 slides within the opening 18 toward the mounting hole 20, it pushes the limiting portion 15 downward, reducing the height of the limiting area 19.

[0054] The take-up head 14 is used to curl the edge of the workpiece 5. One end of the take-up head 14 is provided with a rotating shaft 16. The rotating shaft 16 is provided with a bearing 51. The bearing 51 is set in the mounting hole 20. The rotating shaft 16 passes through the through hole 21 and the limiting area 19 and is placed in the rotating hole 22.

[0055] The rotating shaft 16 is provided with a locking port 31. The cross-section of the locking port 31 is a right-angled triangle. The locking port 31 is provided with an inclined mating surface 52 and a vertically arranged blocking surface 43. The second wall surface 42 and the vertical surface 34 are in contact with the blocking surface 43.

[0056] When the rotating shaft 16 is inserted, it pushes the elastic arm 36 and the limiting protrusion 30, and then keeps the second wall surface 42 and the vertical surface 34 in contact with the blocking surface 43, thus confining the rotating shaft 16 within the limiting area 19.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
