Description

Technical Field

[0001] This utility model relates to the technical field of aluminum profile processing equipment, and in particular to a punch adjustment device for drilling holes in aluminum profiles. Background Technology

[0002] When connecting the ends of aluminum profile door and window frames, corner brackets are commonly used for fixation. Before installing the corner brackets, holes need to be drilled at the ends of the two aluminum profiles to be joined, including mounting holes and glue injection holes. The diameter of the glue injection hole is generally smaller than the mounting hole, and only one end of the profile needs to be drilled. Therefore, existing aluminum profile drilling equipment has an adjustment device to determine whether to drill the glue injection hole. This adjustment device is achieved by pulling a lever, but during use, workers may inadvertently trigger the lever, leading to accidental drilling. Therefore, designing an adjustment device that is less prone to accidental operation is essential. Utility Model Content

The center of the semi-circular punch clearance hole is located inside the circular adjustment blind hole. A glue injection punch mounting hole extends downward from the bottom of the semi-circular punch clearance hole. An adjustment opening extends from the outer circumference of the circular adjustment blind hole onto the side of the punch adjustment seat. A rotating shaft is fixedly installed at the center of the circular adjustment blind hole, and a limiting shaft is fixedly installed on the outer circumference of the circular adjustment blind hole. The glue injection punch mounting hole and the riveting... All punch mounting holes are stepped holes. A glue-injecting punch is movably mounted in the glue-injecting punch mounting hole, and a riveting punch is movably mounted in the riveting punch mounting hole. A cylindrical adjusting block is rotatably mounted in the circular adjusting blind hole. The center of the adjusting block has a rotating hole that rotates around the rotating shaft. The outer circumference of the adjusting block has a limiting notch that cooperates with the limiting shaft. The limiting notch includes an open end and a closed end. The outer circumference of the adjusting block also has a semi-circular punch clearance notch that cooperates with the semi-circular punch clearance hole. When the limiting shaft abuts against the open end of the limiting notch, the glue-injecting punch can pass through the semi-circular punch clearance hole and move upwards. When the limiting shaft abuts against the closed end of the limiting notch, the glue-injecting punch cannot pass through the semi-circular punch clearance hole and move upwards.

[0005] As a preferred technical solution, both the open end and the closed end of the limiting notch are arc-shaped notches, the diameter of the arc-shaped notch is the same as the diameter of the limiting shaft, and the angle between the two lines connecting the center of the open end and the closed end to the center of the rotating shaft is 45°.

[0006] As a preferred technical solution, the stepped hole of the glue injection punch mounting hole includes an upper glue injection hole and a lower glue injection hole. The diameter of the upper glue injection hole is larger than the diameter of the lower glue injection hole. The top of the glue injection hole punch is provided with a cylindrical boss. The diameter of the upper glue injection hole is the same as the diameter of the cylindrical boss, and the diameter of the lower glue injection hole is the same as the diameter of the glue injection hole punch.

[0007] As a preferred technical solution, the diameter of the semi-circular punch clearance hole is larger than the diameter of the glue injection hole, and the diameter of the semi-circular punch clearance hole is equal to the diameter of the semi-circular punch clearance notch. When the limiting shaft abuts against the open end of the limiting notch, the semi-circular punch clearance notch and the semi-circular punch clearance hole are coaxial.

[0008] As a preferred technical solution, the stepped hole of the riveting punch mounting hole includes an upper riveting hole and a lower riveting hole. The diameter of the upper riveting hole is larger than the diameter of the lower riveting hole. The top of the riveting punch is provided with a cylindrical boss. The diameter of the upper riveting hole is the same as the diameter of the cylindrical boss. The depth of the upper riveting hole is the same as the height of the cylindrical boss. The diameter of the lower riveting hole is the same as the diameter of the riveting punch.

[0009] As a preferred technical solution, there are two elongated through holes, the two elongated through holes are the same size, and their center lines are located on the same straight line.

[0010] As a preferred technical solution, the heights of the rotating shaft and the limiting shaft are consistent with the depth of the circular adjustment blind hole.

[0011] As a preferred technical solution, the thickness of the adjusting block is consistent with the depth of the circular adjusting blind hole.

[0012] Due to the adoption of the above technical solution, the punch adjustment device for drilling aluminum profiles includes a cuboid-shaped punch adjustment seat. One side of the punch adjustment seat has a long slotted through hole, and the other side of the punch adjustment seat has, in sequence, a riveting punch mounting hole, a circular adjustment blind hole, and a semi-circular punch clearance hole. The circular adjustment blind hole and the semi-circular punch clearance hole intersect and have the same depth. The center of the semi-circular punch clearance hole is located inside the circular adjustment blind hole. A glue injection punch mounting hole extends downwards from the bottom of the semi-circular punch clearance hole. The outer periphery of the circular adjustment blind hole extends out of the side of the punch adjustment seat. It has an adjustment opening, a rotating shaft is fixedly installed at the center of the circular adjustment blind hole, and a limit shaft is fixedly installed on the outer circumference of the circular adjustment blind hole. Both the glue injection punch mounting hole and the riveting punch mounting hole are stepped holes. A glue injection punch is movably installed in the glue injection punch mounting hole, and a riveting punch is movably installed in the riveting punch mounting hole. A cylindrical adjustment block is rotatably installed inside the circular adjustment blind hole. The center of the adjustment block has a rotating hole that rotates around the rotating shaft, and the outer circumference of the adjustment block has a limit notch for use with the limit shaft. The limit notch includes an open end and a closed end. The outer circumference of the adjustment block also... The device includes a semi-circular punch clearance notch for use with a semi-circular punch clearance hole. When the limiting shaft abuts against the open end of the limiting notch, the injection hole punch can pass through the semi-circular punch clearance hole and move upward. When the limiting shaft abuts against the closed end of the limiting notch, the injection hole punch cannot pass through the semi-circular punch clearance hole and move upward. The beneficial effect of this invention is that when drilling holes in aluminum profiles, and when only one corner bracket mounting hole needs to be drilled in the aluminum profile, the opening or closing end of the limiting notch in contact with the limiting shaft can be adjusted by rotating the adjusting block. The rotating hole of the adjusting block rotates around the rotating shaft. The rotation stroke is located between the open and closed ends of the limiting notch, with a rotation angle of 45°. When the open end contacts the limiting shaft, the semi-circular punch clearance hole and the semi-circular punch clearance notch form a complete circular hole, allowing the tip of the glue injection hole punch to pass through this hole and move upward when the top plate is pressed down. At this time, no hole is drilled on the profile. When the closed end contacts the limiting shaft, the semi-circular punch clearance hole and the semi-circular punch clearance notch are exactly misaligned, preventing the tip of the glue injection hole punch from passing through the adjusting block and preventing upward movement when the top plate is pressed down. At this time, the hole is drilled on the profile. Therefore, rotating the adjusting block allows for a very convenient decision on whether to drill a glue injection hole in the aluminum profile. This utility model has a simple structure, is easy to adjust, convenient to operate, effectively prevents misoperation, and well meets the drilling requirements of different aluminum profiles and different angle brackets.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0027] like Figures 1 to 11 As shown, the punch adjustment device for drilling aluminum profiles includes a rectangular punch adjustment seat 1. One side of the punch adjustment seat 1 has a long slotted through hole 2. The other side of the punch adjustment seat 1 has a riveting punch mounting hole 3, a circular adjustment blind hole 4, and a semi-circular punch clearance hole 5. The circular adjustment blind hole 4 intersects with the semi-circular punch clearance hole 5, and both have the same depth. The center of the semi-circular punch clearance hole 5 is located inside the circular adjustment blind hole 4. A glue injection punch mounting hole 6 extends downwards from the bottom of the semi-circular punch clearance hole 5. An adjustment opening 9 extends from the outer circumference of the circular adjustment blind hole 4 onto the side of the punch adjustment seat 1. A rotating shaft 10 is fixedly installed at the center of the circular adjustment blind hole 4, and a limiting shaft 11 is fixedly installed on the outer circumference of the circular adjustment blind hole 4. Both the glue injection punch mounting hole 6 and the riveting punch mounting hole 3 are stepped holes. A glue injection hole punch 7 is installed vertically within the 6-hole, and a riveting hole punch 8 is installed vertically within the 3-hole. A cylindrical adjusting block 12 is rotatably installed within the circular adjusting blind hole 4. The center of the adjusting block 12 has a rotating hole 13 that rotates around the rotating shaft 10. The outer circumferential surface of the adjusting block 12 has a limiting notch 14 that cooperates with the limiting shaft 11. The limiting notch 14 includes an open end 1401 and a closed end 1402. The outer circumferential surface of the adjusting block 12 also has a semi-circular punch clearance notch 15 that cooperates with the semi-circular punch clearance hole 5. When the limiting shaft 11 abuts against the open end 1401 of the limiting notch 14, the glue injection hole punch 7 can pass through the semi-circular punch clearance hole 5 and move upward. When the limiting shaft 11 abuts against the closed end 1402 of the limiting notch 14, the glue injection hole punch 7 cannot pass through the semi-circular punch clearance hole 5 and move upward.

[0028] When drilling holes in aluminum profiles is required, and when only one corner bracket mounting hole is needed, the open end 1401 or the closed end 1402 of the limiting notch 14 can be adjusted to contact the limiting shaft 11 by rotating the adjusting block 12. The rotating hole 13 of the adjusting block 12 rotates around the rotating shaft 10, and the rotation stroke is between the open end 1401 and the closed end 1402 of the limiting notch 14, with a rotation angle of 45°. When the open end 1401 is rotated to contact the limiting shaft 11, the semi-circular punch clearance hole 5 and the semi-circular punch clearance notch 15 form a complete circular hole. The tip of the glue injection hole punch 7 can pass through this circular hole and can move upward when the top plate 16 is pressed down. At this time, no hole is drilled on the profile. When the closed end 1402 is rotated to contact the limiting shaft 11, the semi-circular punch clearance hole 5 and the semi-circular punch clearance notch 15 are exactly misaligned. The tip of the glue injection hole punch 7 cannot pass through the adjusting block 12 and cannot move upward when the top plate 16 is pressed down. At this time, the hole is drilled on the profile. Therefore, by rotating the adjusting block 12, it is very convenient to determine whether to drill a glue injection hole on the aluminum profile. This utility model has a simple structure, is easy to adjust, is convenient to operate, effectively prevents misoperation, and well meets the drilling needs of different aluminum profiles and different corner brackets.

[0029] like Figure 9 As shown, both the open end 1401 and the closed end 1402 of the limiting notch 14 are arc-shaped notches. The diameter of the arc-shaped notches is the same as the diameter of the limiting shaft 11. The angle between the two lines connecting the centers of the open end 1401 and the closed end 1402 to the center of the rotating shaft 10 is 45°. The arc-shaped notches of the open end 1401 and the closed end 1402 are designed to fit against the outer circumferential surface of the limiting shaft 11. The surface connecting the open end 1401 and the closed end 1402 is also an arc surface, which remains in contact with the limiting post during the displacement around the limiting shaft 11.

[0030] like Figure 3 , Figure 5 and Figure 8 As shown, the stepped hole of the glue injection punch mounting hole 6 includes an upper glue injection hole 601 and a lower glue injection hole 602. The diameter of the upper glue injection hole 601 is larger than the diameter of the lower glue injection hole 602. The top of the glue injection hole punch 7 is provided with a cylindrical boss. The diameter of the upper glue injection hole 601 is the same as the diameter of the cylindrical boss, and the diameter of the lower glue injection hole 602 is the same as the diameter of the glue injection hole punch 7. After the glue injection hole punch 7 is inserted into the glue injection punch mounting hole 6, the cylindrical boss is stuck in the upper glue injection hole 601 to prevent the glue injection hole punch 7 from falling downward. Whether it can move upward depends on the rotation direction of the adjusting block 12. When the adjusting block 12 blocks the semi-circular punch clearance hole 5, the glue injection hole punch 7 cannot move upward and is in the drilling state.

[0031] like Figure 2 , Figure 3 and Figure 7 As shown, the diameter of the semi-circular punch clearance hole 5 is larger than the diameter of the glue injection hole 601, and the diameter of the semi-circular punch clearance hole 5 is equal to the diameter of the semi-circular punch clearance notch 15. When the limiting shaft 11 abuts against the open end 1401 of the limiting notch 14, the semi-circular punch clearance notch 15 and the semi-circular punch clearance hole 5 are coaxial. The diameter of the semi-circular punch clearance hole 5 is larger than the diameter of the glue injection hole 601 to facilitate the installation of the glue injection hole punch 7. When the limiting shaft 11 abuts against the open end 1401 of the limiting notch 14, the glue injection hole punch 7 has sufficient clearance space to move upward and avoid the hole, thus remaining in a non-drilling state.

[0032] like Figure 3 , Figure 5 and Figure 8As shown, the stepped hole of the riveting punch mounting hole 3 includes an upper riveting hole 301 and a lower riveting hole 302. The diameter of the upper riveting hole 301 is larger than the diameter of the lower riveting hole 302. The top of the riveting hole punch 8 is provided with a cylindrical boss. The diameter of the upper riveting hole 301 is the same as the diameter of the cylindrical boss, and the depth of the upper riveting hole 301 is the same as the height of the cylindrical boss. The diameter of the lower riveting hole 302 is the same as the diameter of the riveting hole punch 8. After the punch adjusting seat 1 is installed, its upper surface abuts against the upper adjusting seat 17. Therefore, the riveting hole punch 8 will not move upward during punching, thus completing the punching process.

[0033] like Figure 1 and Figure 2 As shown, there are two elongated through holes 2, both of the same size, and their center lines are on the same straight line. The elongated through holes 2 are used to mate with the threaded blind holes on the upper adjusting seat 17 to adjust the front and rear positions of the punch adjusting seat 1, adapting to the processing requirements of different profiles. The elongated through holes 2 are located on the same straight line to facilitate bidirectional adjustment; when two adjacent punch adjusting seats 1 move forward and backward respectively, they can be offset by the length of the two elongated through holes 2.

[0034] like Figures 1 to 4 As shown, the heights of the rotating shaft 10 and the limiting shaft 11 are consistent with the depth of the circular adjustment blind hole 4. This ensures that the rotating shaft 10 and the limiting shaft 11 do not protrude from the outer surface of the punch adjustment seat 1, preventing interference during installation.

[0035] like Figure 1 and Figure 3 As shown, the thickness of the adjusting block 12 is consistent with the depth of the circular adjusting blind hole 4. This is so that when the limiting shaft 11 abuts against the closed end 1402 of the limiting notch 14, the top of the injection hole punch 7 is the adjusting block 12. If the thickness of the adjusting block 12 is less than the depth of the circular adjusting blind hole 4, the injection hole punch 7 will push against the adjusting block 12 and move upward when the hydraulic cylinder is pressed down, thus failing to achieve the drilling function. Therefore, the thickness of the adjusting block 12 must be consistent with the depth of the circular adjusting blind hole 4 to achieve normal drilling. Small protrusions can be provided on the side of the adjusting block 12 for anti-slip during operation.

[0036] The usage process of this utility model is as follows:

[0037] Adjust the adjusting block 12 of the punch adjusting seat 1 according to whether the profile needs to be punched with glue injection holes, and determine the rotation position of the adjusting block 12. When punching glue injection holes, control the adjusting block 12 to rotate to the desired position. Figure 4 and Figure 5In the state shown, the limiting shaft 11 abuts against the closed end 1402 of the limiting notch 14. At this time, the adjusting block 12 partially blocks the glue injection punch mounting hole 6. Thus, when the hydraulic cylinder applies pressure to the top plate 16, and the top plate 16 is pressed down, the glue injection punch 7, under the blocking effect of the adjusting block 12, cannot move upward and will contact the aluminum profile to complete the glue injection hole. At this time, the upper surface of the riveting hole punch 8 cannot move upward under the abutment of the upper adjusting seat 17, thus completing the riveting hole. When not drilling the glue injection hole, the adjusting block 12 is rotated to the position shown. Figure 2 and Figure 3 In the state shown, the limiting shaft 11 and the opening end 1401 of the limiting notch 14 are in contact. At this time, the semi-circular punch clearance hole 5 and the semi-circular punch clearance notch 15 are coaxial. When the top plate 16 is pressed down, the glue injection hole punch 7 can move upward and will not contact the aluminum profile, so it will not make a glue injection hole. At this time, the upper surface of the riveting hole punch 8 cannot move upward under the abutment of the upper adjusting seat 17, thus completing the riveting hole.

[0038] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
