Description

Technical Field

[0001] This utility model relates to the field of flange machine drilling technology, and in particular to a flange machine 45-degree side punch riveting drilling mechanism. Background Technology

[0002] The side-punch riveting and drilling mechanism is a special equipment component designed for processing non-front-facing rivet holes. Its core function is to process rivet holes at an inclined angle on the surface of workpieces (such as flanges, steel structure connecting plates, and automobile chassis brackets) to meet the spatial interlacing connection requirements of components. The spacing between the pressure rollers can be adjusted to adapt to the drilling requirements of plates of different thicknesses.

[0003] Adjust the spacing between the pressure rollers according to the thickness of the sheet material, and then adjust the spacing between the tightening rollers according to the width of the sheet material. Pass the sheet material through the pressure rollers and into the drilling part for drilling. Finally, it is sent out from between the tightening rollers. Continue drilling the sheet material.

[0004] The existing side-punch riveting and drilling mechanism requires the use of a wrench to adjust the bolts when adjusting the distance between the pressure roller and the tightening wheel. This is not only time-consuming and labor-intensive, but also makes it impossible to accurately control the downward adjustment distance at both ends of the pressure roller. The same applies to the tightening wheel, making it impossible to accurately adjust the two tightening wheels to always be symmetrical along the mechanism, which affects the drilling efficiency of the sheet metal. Therefore, a 45-degree side-punch riveting and drilling mechanism for flange machines is proposed. Utility Model Content

The inner toothed plate is removed from the two loop frames. When the bidirectional lead screw is driven to rotate, with the assistance of the two T-shaped plates, the two T-shaped plates move towards each other, causing each pair of symmetrical tightening wheels to move towards each other, while adjusting the distance between each pair of tightening wheels. This facilitates the adjustment of the distance between each pair of tightening wheels and adapts to the processing of sheet metal of different widths. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention, which provides a flange machine 45-degree side punching rivet drilling mechanism, comprising: Support frame 1, with a perforated component installed at the center of support frame 1; Adjustment mechanism 2 is located inside the support frame 1. Adjustment mechanism 2 includes a force-bearing roller 201 that is movably installed inside the support frame 1 via a bearing seat. A pressure roller 202 is provided on the top of the two force-bearing rollers 201 on opposite sides. A protective cover 207 is provided on the top of the support frame 1. A rotating rod 205 is movably installed inside the protective cover 207. A driving bevel gear 206 is symmetrically installed on the outer surface of the rotating rod 205. A one-way screw 203 is symmetrically arranged inside the support frame 1. A driven bevel gear 204 adapted to the driving bevel gear 206 is installed on the top of the one-way screw 203.

[0024] like Figure 3 As shown, in this embodiment, the outer surface of the shaft of the lower pressure roller 202 is provided with a threaded hole adapted to the one-way lead screw 203. The one-way lead screw 203 meshes with the threaded hole. The outer surface of the support frame 1 is symmetrically provided with straight slots adapted to the lower pressure roller 202. The two ends of the lower pressure roller 202 are slidably connected inside the straight slots. The driven bevel gear 204 meshes with the driving bevel gear 206. The driven bevel gear 204 is located in the inner cavity of the protective cover 207. When the rotating rod 205 is driven to rotate, the driven bevel gear 204 can be driven to rotate through the driving bevel gear 206. With the cooperation of the one-way lead screw 203 and the threaded hole of the lower pressure roller 202, the two ends of the lower pressure roller 202 move up and down in the straight slot at the same time, so that the lower pressure roller 202 and the two force rollers 201 always remain parallel to each other, which is suitable for the flattening operation of plates of different thicknesses.

[0025] like Figure 3As shown, in this embodiment, a perforated plate 208 is movably installed inside the rotating rod 205. A plurality of limiting blocks 209 adapted to the perforated plate 208 are arranged circumferentially on one side of the protective cover 207. A first spring 210 is provided on one side of the perforated plate 208. Under the action of the first spring 210, a pushing force is applied to the perforated plate 208 in the direction of the protective cover 207, so that the perforated plate 208 is located on the opposite side of every two limiting blocks 209, thus restricting the rotation of the first spring 210.

[0026] like Figure 3 As shown, in this embodiment, the outer surface of the rotating rod 205 is provided with a double-opening slide groove adapted to the hollow plate 208. The hollow plate 208 is slidably connected inside the double-opening slide groove. The hollow plate 208 is located on the opposite side of each pair of limiting blocks 209 and contacts the protective cover 207. Under the action of the double-opening slide groove, the hollow plate 208 will not fall off the rotating rod 205 during the movement of the hollow plate 208. Furthermore, the rotation of the hollow plate 208 can drive the rotating rod 205 to rotate.

[0027] Furthermore, the punching component belongs to a conventional punching method well known to those skilled in the art, and its specific parameters can be selected according to actual needs. When adjusting the distance between the pressure roller 202 and the two force rollers 201, the perforated plate 208 is manually pulled outward inside the first spring 210, causing the perforated plate 208 to break free from the restriction of the limiting block 209. The perforated plate 208 compresses the first spring 210 and deforms. At this time, a rotational force is applied to the perforated plate 208, which drives the rotating rod 205 to rotate inside the protective cover 207. The rotating rod 205 drives the two active bevel teeth. When wheel 206 rotates, the two active bevel gears 206 drive the corresponding one-way lead screws 203 to rotate. The two one-way lead screws 203 move the two ends of the pressing roller 202 upward in the corresponding straight grooves of the support frame 1, adjusting the distance between the pressing roller 202 and the two force-bearing rollers 201. After the adjustment is completed, the force applied to the hollow plate 208 is removed. Under the action of the first spring 210, a pushing force is applied to the hollow plate 208 in the direction of the protective cover 207, so that the hollow plate 208 is stuck on the opposite side of the two limit blocks 209, thus completing the adjustment of the spacing of the pressing roller 202.

[0028] Example 2 Reference Figures 4-6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The tightening mechanism 3 is set inside the support frame 1. The tightening mechanism 3 includes a spiral frame 301 symmetrically installed inside the support frame 1. Tightening wheels 303 are symmetrically and movably installed inside the spiral frame 301. A T-shaped plate 302 is provided on one side of the two tightening wheels 303. A bidirectional lead screw 304 adapted to the T-shaped plate 302 is movably installed inside the support frame 1 through a bearing seat.

[0029] like Figure 5 As shown, in this embodiment, two T-shaped plates 302 are symmetrically and movably installed on the outside of the bidirectional lead screw 304 through threaded sleeves. One end of the bidirectional lead screw 304 extends to the outside of the support frame 1 and is equipped with a motor 305. The other end of the bidirectional lead screw 304 extends to the outside of the support frame 1 and is provided with an external gear ring 306. An internal gear plate 307 adapted to the external gear ring 306 is movably installed inside the loop frame 301. The internal gear plate 307 is movably engaged with the outside of the external gear ring 306. After the bidirectional lead screw 304 stops rotating, the internal gear plate 307 is sleeved on the outside of the external gear ring 306 and the internal gear plate 307 is locked in the two loop frames 301 to restrict the rotation of the bidirectional lead screw 304 and apply a certain self-locking force to the bidirectional lead screw 304.

[0030] like Figure 5 and Figure 6 As shown in this embodiment, each of the two loop frames 301 has a slot on its opposite side that is adapted to the inner toothed plate 307. The inner toothed plate 307 is movably installed inside the slot. A limiting groove is opened at the bottom of the inner surface of the slot. A stop block 309 adapted to the inner toothed plate 307 is movably installed inside the limiting groove. A second spring 308 is installed at the bottom of the stop block 309. Under the action of the second spring 308, an upward pushing force is applied to the stop block 309. After the inner toothed plate 307 is completely pushed into the slot, the stop block 309 is locked on the outside of the inner toothed plate 307, fixing the inner toothed plate 307 in the slot.

[0031] Furthermore, the inner gear plate 307 is manually pulled out from the opposite side of the two loop frames 301. During the pulling process, the inner gear plate 307 applies a downward squeezing force to the stop block 309. The stop block 309 compresses and deforms the second spring 308. After the inner gear plate 307 is removed from the outer gear ring 306, the motor 305 is controlled to run. The motor 305 drives the bidirectional lead screw 304 to rotate. The bidirectional lead screw 304 drives the two T-shaped plates 302 to move simultaneously. The T-shaped plates 302 drive the corresponding two tensioning wheels 3 03. Movement: Under the action of the two T-shaped plates 302, move each pair of symmetrical tightening wheels 303 toward each other, adjusting the distance between each pair of tightening wheels 303 to match the width of the plate. After adjustment, place the outer gear ring 306 parallel to the outer gear ring 306, and lock the inner gear plate 307 on the outside of the outer gear ring 306. At this time, under the action of the two second springs 308, push the corresponding stop block 309 upward, so that the stop block 309 is locked on the outside of the inner gear plate 307, thus restricting the rotation of the bidirectional lead screw 304.

[0032] Working principle: The punching mechanism is installed at a 45-degree angle on the flange machine. A wiring harness connects the mechanism to an external power supply and controller. The fitting distance between the lower pressure roller 202 and the two force-bearing rollers 201 is adjusted according to the required thickness of the sheet material to be punched. The perforated plate 208 is manually pulled outward from inside the first spring 210, causing it to disengage from the limiting block 209. The perforated plate 208 deforms by compressing the first spring 210. At this point, a rotational force is applied to the perforated plate 208, causing it to drive the rotating rod 205 to rotate within the protective cover 207. The rotating rod 205 then drives the two active bevel gears 206 to rotate. Two active bevel gears 206 drive the corresponding one-way lead screws 203 to rotate. The two one-way lead screws 203 move the two ends of the lower pressure roller 202 upward in the corresponding straight grooves of the support frame 1, adjusting the distance between the lower pressure roller 202 and the two force-bearing rollers 201. After the adjustment is completed, the force applied to the hollow plate 208 is removed. Under the action of the first spring 210, a pushing force is applied to the hollow plate 208 in the direction of the protective cover 207, so that the hollow plate 208 is stuck on the opposite side of the two limit blocks 209, thus completing the adjustment of the spacing of the lower pressure roller 202. Then, the spacing between each pair of tightening rollers 303 is adjusted according to the width of the plate. At this point, manually pull the inner toothed plate 307 out from the opposite side of the two loop frames 301. During the pulling process, the inner toothed plate 307 applies a downward squeezing force to the stop block 309, which compresses and deforms the second spring 308. After removing the inner toothed plate 307 from the outer toothed ring 306, control the motor 305 to run. The motor 305 drives the bidirectional lead screw 304 to rotate, and the bidirectional lead screw 304 drives the two T-shaped plates 302 to move simultaneously. The T-shaped plates 302 drive the corresponding two tensioning wheels 303 to move. Under the action of the two T-shaped plates 302, each pair of symmetrical tensioning wheels 303 moves towards each other. Move the plate and adjust the distance between each pair of tightening rollers 303 to match the width of the plate. After adjustment, place the outer gear ring 306 parallel to the outer gear ring 306 and clamp the inner gear plate 307 on the outside of the outer gear ring 306. At this time, under the action of the two second springs 308, push the corresponding stop block 309 upward so that the stop block 309 is clamped on the outside of the inner gear plate 307, thus restricting the rotation of the bidirectional lead screw 304. After adjustment, insert one end of the plate through the top of the two force rollers 201, pass the other end of the plate through the punching component, and finally pass between each pair of tightening rollers 303. Finally, punch holes in the plate in an orderly manner through the punching component.
