Description

Technical Field

[0001] The invention relates to the technical field of aluminum plate processing, and in particular to a positioning and trimming device for aluminum plate processing. Background Art

[0002] Aluminum plate refers to a rectangular plate made by rolling aluminum ingots. With the development of science and technology, aluminum plate is widely used in hardware devices. It not only has good plasticity, but also has beautiful appearance. Due to the production process of aluminum plate, its edges and corners will produce a lot of burrs, which does not meet the product requirements. At this time, the burrs of the plate need to be trimmed to make the plate meet the required specifications.

[0003] The Chinese patent application number 202222645256.0 provides an aluminum plate trimming device, including: a placement table, a fixing mechanism, and a trimming mechanism. The upper surface of the placement table is provided with a mounting groove, and a rotating roller is installed in the mounting groove; the fixing mechanism includes a clamping member, and the clamping member is arranged on both sides of the placement table; the trimming mechanism includes a processing table and at least one cutting motor, the processing table is located at the lower part of the placement table, and the cutting motor is symmetrically arranged on both sides of the placement table. This technical solution is suitable for fixing aluminum materials of different widths by adjusting the telescopic rod to change the position of the first clamp block and the second clamp block; by adjusting the first clamp block and the second clamp block in the opposite or relative direction, the distance between the first clamp block and the second clamp block is changed, so that it is suitable for fixing aluminum plates of different thicknesses. The above-mentioned mechanism is suitable for trimming aluminum plates of various specifications, but the following problems still exist in practical applications, specifically: 1. In this scheme, the aluminum plate is manually pushed to cut the edges, and the aluminum plate moves and cuts automatically under the rotation of the rotating roller. The degree of automation is not high and the work intensity of the staff will be increased during the pushing process. 2. In this solution, multiple telescopic rods are used separately, and the telescopic length of each telescopic rod needs to be adjusted to the same length and then positioned by a locking piece, which is cumbersome to operate; 3. The two cutting motors need to be adjusted individually through the hydraulic cylinders, which is inconvenient to arrange the cutting motors symmetrically with the central axis of the placement table as the symmetry axis; Therefore, the present invention provides a positioning and trimming device for aluminum plate processing to solve the above problems.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the technical scheme in the specific implementation mode of the present invention is clearly and completely described below to further illustrate the present invention. Obviously, the specific implementation mode described is only a part of the implementation mode of the present invention, rather than all styles.

[0021] The following is combined with Figure 1-16 The present invention is described in further detail.

[0022] Embodiment 1: A positioning and trimming device for aluminum plate processing, comprising a supporting leg 1, a placing table 2 is installed on the upper end of the supporting leg 1, an active roller 3 and a driven roller assembly are embedded and rotatably arranged on the placing table 2, and the active roller 3 and the driven roller assembly are driven by a transmission belt 4, a mounting block 5 is installed on the upper end of the placing table 2, a bearing seat 6 is installed on the upper end of the mounting block 5, a bidirectional screw rod 7 is rotatably connected in the bearing seat 6, a movable block 8 is sleeved on the thread of the bidirectional screw rod 7, supporting plates 9 are installed on both sides of the placing table 2, the bottom of the movable block 8 is slidably connected to the upper surface of the supporting plate 9, a first matching block 10 is fixedly installed on the side of the movable block 8, a second matching block 11 is fixedly installed on the side of the first matching block 10, a mounting seat 12 is fixedly installed on the upper end of the second matching block 11, and a cutting motor 13 is installed on the mounting seat 12; When in use, the active roller 3 is connected to an external driving motor, and the driving motor drives the active roller 3 to rotate. With the cooperation of the driven roller and the transmission belt 4, the aluminum plate is placed on the transmission belt 4 to transport the transmission belt 4, which solves the problem of manually pushing the aluminum plate for edge trimming, the low degree of automation and the increased work intensity of the staff during the plate pushing process. It can effectively improve the degree of automation and reduce the work intensity of the staff. The staff rotates the two-way screw rod 7 by hand. Since the bottom of the movable block 8 is slidingly connected to the upper surface of the support plate 9, the movable block 8 undergoes relative displacement under the cooperation of the threaded connection. Since the threads at both ends of the two-way screw rod 7 rotate in opposite directions, the two movable blocks 8 will move away from or approach each other, thereby driving the first matching block 10, the second matching block 11 and the mounting seat 12 to move synchronously, that is, adjusting the position of the cutting motor 13 according to actual application requirements, so that the cutting motor 13 can be easily arranged symmetrically with the central axis of the placement table 2 as the symmetry axis, thereby improving work efficiency and the symmetrical edge trimming effect of the aluminum plate.

[0023] A positioning pin 14 is embedded in the placement table 2, and a rotating member 15 is rotatably connected to the outside of the positioning pin 14. A connecting member 16 is provided on the outer sleeve of the rotating member 15, and a first fixing pin 17 is fixedly installed at both ends of the connecting member 16. L-shaped movable plates 21 are provided on both sides of the placement table 2, and a second fixing pin 18 is fixedly installed on the L-shaped movable plate 21. A connecting rod 19 is movably connected between the first fixing pin 17 and the second fixing pin 18. A guide rod 20 is provided on the side wall of the placement table 2, and the L-shaped movable plate 21 is penetrated by the guide rod 20 and movably connected to the guide rod 20. A positioning component is detachably installed on the upper end of the L-shaped movable plate 21.

[0024] like Figure 5 As shown, when in use, the staff manually twists the rotating member 15, and the connecting member 16 undergoes a synchronous angle change. With the center of the positioning pin 14 as the axis, the upper end of the connecting member 16 moves to the left and the lower end moves to the right under the action of the hinge, that is, the two L-shaped movable plates 21 will move away from each other at this time. According to the above steps, the rotating member 15 is twisted in the opposite direction to adjust the two L-shaped movable plates 21 to be closer to each other. The guide rod 20 supports and guides the L-shaped movable plate 21. The position of the L-shaped movable plate 21 is flexible and changeable, so it is suitable for aluminum plates of different widths, so that the positioning components installed on the upper end of the L-shaped movable plate 21 can be adapted and adjusted according to the aluminum plate, which solves the problem that the original multiple telescopic rods are used separately and the telescopic length of each telescopic rod needs to be adjusted to a consistent cumbersome operation.

[0025] In this embodiment, a ring 22 is fixedly connected to the outside of the bidirectional screw rod 7, and a gripping protrusion 23 is fixedly connected to the side of the ring 22. The staff can drive the ring 22 to rotate synchronously by twisting the gripping protrusion 23, and the ring 22 drives the bidirectional screw rod 7 to rotate synchronously, which makes the operation more convenient.

[0026] The L-shaped movable plate 21 includes a vertical portion 35 and a horizontal portion 36 . The guide rod 20 passes through the vertical portion 35 , and the second fixing pin 18 is installed on the lower surface of the horizontal portion 36 .

[0027] In this embodiment, after the position of the L-shaped movable plate 21 is determined, a locking assembly can be added to limit the L-shaped movable plate 21 to prevent the L-shaped movable plate 21 from sliding along the guide rod 20 due to misoperation. The specific preferred scheme is: the outer wall of the vertical portion 35 is connected to a locking plate 37, the locking plate 37 is penetrated by the guide rod 20 and is movably connected to the guide rod 20, the side wall of the support plate 9 is provided with a sliding groove 38 that slidably cooperates with the locking plate 37, the lower end surface of the sliding groove 38 is provided with an extension groove 39 inwardly, and a locking tooth 40 is provided in the extension groove 39, and a second cavity 41, a third cavity 43 and a fourth cavity 44 are provided inside the locking plate 37, and the second cavity 41, the third cavity 43 and the fourth cavity 44 are provided inside. The four cavities 44 are connected to each other. A first locking rod 45 is slidably arranged in the second cavity 41. Two parallel protrusions 46 are installed at the end of the first locking rod 45. A third fixing pin 47 is connected between the two protrusions 46. A locking matching block 48 is movably arranged in the third cavity 43. The locking matching block 48 is located in the gap between the two protrusions 46. The third fixing pin 47 passes through the locking matching block 48. The locking matching block 48 is provided with a matching through groove 42. The third fixing pin 47 is slidably arranged in the matching through groove 42. A second locking rod 49 is slidably arranged in the fourth cavity 44. One end of the second locking rod 49 is connected to the locking matching block 48, and the other end is embedded in the gap of the locking tooth 40.

[0028] like Figure 9-11 As shown, Fig. 9 In locked state, Fig.10 It is in the unlocked state. When unlocking, the first locking rod 45 is pushed to the left, and the third fixing pin 47 slides along the setting direction of the matching through groove 42, which will push the locking matching block 48 to move upward, and the locking matching block 48 drives the second locking rod 49 to move upward and away from the locking tooth 40 simultaneously. At this time, the position of the locking plate 37 can be changed. After the adjustment is completed, follow the above steps in reverse order to make the second locking rod 49 embed into the gap of the locking tooth 40 under its own gravity, so as to limit the L-shaped movable plate 21 to prevent the L-shaped movable plate 21 from sliding along the guide rod 20 due to misoperation, thereby affecting the use effect.

[0029] In this embodiment, the positioning assembly includes a positioning plate 24 arranged at the upper end of the L-shaped movable plate 21, a clamping plate 25 is provided above the positioning plate 24, and an adjustment assembly for changing the distance between the positioning plate 24 and the clamping plate 25 is provided between the positioning plate 24 and the clamping plate 25. The adjustment assembly includes an outer adjusting rod 26 fixedly installed on the upper surface of the positioning plate 24, a first cavity 27 is provided in the outer adjusting rod 26, and an inner adjusting rod 28 is rotatably connected to the upper surface, a threaded countersunk hole 29 is provided on the lower surface of the clamping plate 25, and the upper end of the inner adjusting rod 28 is threadedly connected to the threaded countersunk hole 29, and a matching countersunk hole 30 is also provided on the lower surface of the clamping plate 25, and a vertical matching rod 31 is fixedly installed on the upper surface of the positioning plate 24, and the upper end of the vertical matching rod 31 is embedded in the matching countersunk hole 30.

[0030] When using the adjustment assembly, rotate the inner adjustment rod 28, and under the threaded connection with the threaded countersunk hole 29 and the guiding action of the vertical matching rod 31, the clamping plate 25 will undergo relative displacement, that is, the vertical height position will change, so as to adapt to aluminum plates of different thicknesses, that is, the lower surface of the aluminum plate is slidingly connected to the upper surface of the placement table 2, and the upper surface of the aluminum plate is slidingly connected to the lower surface of the clamping plate 25.

[0031] The lower end surface of the clamping plate 25 may preferably be provided with a stepped surface 32 to improve the clamping stability effect of the clamping plate 25, and the stepped surface 32 produces a slight abutment height difference, which can be fine-tuned according to actual thickness requirements without using an adjustment component.

[0032] The driven roller assembly includes a first driven roller 33 and a second driven roller 34. The L-shaped movable plate 21 is located between the active roller 3 and the first driven roller 33. The mounting seat 12 is located between the first driven roller 33 and the second driven roller 34. The installation position is reasonable and convenient for the staff to operate, and the aluminum plate transmission effect is achieved at a low and reasonable use cost. The guide rods 20 are two parallel sets, the upper end surface level of the mounting seat 12 is higher than the upper end surface level of the placement table 2, and the upper end surface level of the positioning plate 24 is equal to the upper end surface level of the placement table 2.

[0033] Embodiment 2: In this embodiment, a grinding component is also installed on the front side of the placement table 2 by bolt connection or other detachable connection methods. The grinding component can be used to grind the surface of the cut aluminum plate to remove the burrs on the surface to make it smoother. The installation position of the grinding component is not fixed and can be adaptively adjusted according to the actual width of the aluminum plate. The grinding component includes a C-shaped grinding seat 50, and the side wall of the C-shaped grinding seat 50 is detachably connected to the front side wall of the placement table 2. A deformable connecting bag body 51 is installed on the inner side of the opening of the C-shaped grinding seat 50. The connecting bag body 51 A grinding belt 52 is installed on the inner side of the opening. The material of the grinding belt 52 is a flexible material, such as nylon, which can be deformed. The C-shaped grinding seat 50 and the connecting bag body 51 are both hollow structures. A plurality of air bags 53 are arranged in the connecting bag body 51. In this embodiment, the preferred arrangement of the air bags 53 is as follows: 4 rows are arranged in the horizontal direction of the connecting bag body 51, and 3 columns are arranged in each row. 6 rows are arranged in the vertical direction of the connecting bag body 51, and 3 columns are arranged in each row. The two horizontal and vertical corners are set as combined air bags. The air bags 53 in the combined air bags are arranged in a 2x2 staggered manner. The shape of the whole assembly is approximately rhombus, and an arc plate 61 is provided at the end of the combined airbag, and the other side of the arc plate 61 abuts against the back side of the grinding belt. The material of the arc plate 61 is a flexible material such as rubber, which can be deformed. When used, the airbags 53 at different positions are inflated, and the curvature of the arc plate 61 will change differently. For example, when the two middle airbags 53 are inflated, the curvature of the middle part of the arc plate 61 will be deeper, and when the two side airbags 53 are inflated, the middle part remains unchanged, and the depth of the middle part of the arc plate 61 will be shallower, and the depth of the two sides will be deeper. According to the grinding requirements of the aluminum plate and the specifications of the aluminum plate The flexible adjustment of the grid makes its application range wider. The side surface of the airbag 53 in the length direction is corrugated. The advantage of the corrugation is that when the airbag 53 is squeezed to deform it, the gas filled inside the airbag 53 will only flow along the length direction, that is, the shape in the length direction is changed. Each airbag 53 is connected to an air pump, and the air pump is connected to an external electronic control device. The advantage of using the airbag 53 is that the internal air pressure can be changed and adjusted, which is suitable for grinding aluminum plates of different thicknesses. For example, when the thickness of the aluminum plate is lower, the internal air pressure of the airbag 53 is adjusted to be large, and when the thickness of the aluminum plate is higher, the internal air pressure of the airbag 53 is adjusted to be small.

[0034] It can be used to adapt to at least two situations, such as Fig.13 The first case shown is: when corner edges are required between the upper surface, side surface and lower surface of the cut aluminum plate, the internal air pressure of each airbag is controlled to be equal by an external air pump, so that the connected bag body 51 is in a relatively balanced state at all locations.

[0035] If the pressure P is too large, the air pressure F inside the airbag 53 will be too large, and intermittent irregular bulges will appear on the surface of the connecting bag body 51. If the length of L is too small and the value of d is too small, the air pressure F inside the airbag will be too small, and intermittent depressions will appear on the surface of the connecting bag body 51, affecting the support effect of the C-shaped grinding seat 50. In order to prevent the air pressure inside the airbag 53 from being too large or too small, the air pressure F inside the airbag 53 satisfies: F=ζ3 / 5P·(πr2)2·d·(L-2r)1 / 2; where: F is the air pressure inside the airbag, in pa; ζ is the adjustment coefficient, with a value range of 0.67-0.85; P is the filling pressure, in pa; r is the radius of the airbag cross section, in mm; L is the length of the airbag, in mm; and d is the number of airbags.

[0036] like Fig.14 The second situation shown: when there is no need for edges and corners between the upper surface, side surface and lower surface of the aluminum plate after cutting, that is, the cross-section is a rounded side with an arc, by inflating the combined airbags at the two horizontal and vertical corners, the arc plate 61 is deformed and abuts against the grinding belt 52, thereby pushing and changing the shape of the grinding belt 52. The corners of the grinding belt 52 are rounded, which is easy to operate and increases the scope of application. At the same time, the inflation amount and the internal air pressure of the airbag 53 can be adjusted to adjust the curvature of the grinding belt 52 accordingly.

[0037] When the surface of the aluminum plate is polished, heat is generated due to friction. In order to achieve a cooling effect and extend the use effect and service life of the polishing belt 52, a accommodating box 54 is installed in the C-shaped polishing seat 50. Ventilation pipes 60 are provided at the upper and lower ends of the C-shaped polishing seat 50. Evaporative liquid is stored in the accommodating box 54. The evaporative liquid used in this scheme is preferably acetic acid. Acetic acid will evaporate from liquid to gas at 20°C. First blades 55 are arranged opposite to each other on the upper and lower sides of the accommodating box 54. Heat dissipation teeth 56 are installed on the outside of the C-shaped polishing seat 50. The upper and lower ends of the heat dissipation teeth 56 are connected to the accommodating box 54 and are provided with transmission pipes 57. Hot air enters the C-shaped polishing seat 50 and contacts with the liquid medium. When the liquid evaporates, it absorbs heat to achieve a cooling effect. The heat dissipation teeth 56 installed on the outside 6 and a transmission pipe 57 connected to the accommodating box 54, wherein a second blade 58 is rotatably connected in the transmission pipe, and a synchronization rod 59 is connected between the first blade 55 and the second blade 58.
