Description

Technical Field

[0001] This utility model belongs to the field of screw and fastener processing technology, and specifically relates to a screw and fastener processing pressing device. Background Technology

[0002] Screws are one of the most common fasteners. Fasteners are widely used in the mechanical field and have a wide range of applications in the market. Fasteners come in many varieties and specifications, with a wide range of performance and uses. They are also highly standardized, serialized, and universalized, and are used in various industries. When processing fasteners, it is necessary to clamp them to prevent them from shifting. However, when cutting screws, since screw heads are often composed of polygons, rotation often occurs when clamping and pressing the screw. Therefore, during the cutting length processing, the clamping and pressing device is often not stable enough, resulting in cutting deviations and affecting the process.

[0003] To address this, a screw fastener production pressing device, with announcement number "CN214080300U", includes a base, a housing fixedly connected to the base, a power chamber fixedly connected inside the housing, a drive shaft rotatably connected inside the power chamber, and one end of the drive shaft away from the power chamber rotatably connected to the housing. A first helical gear is fixedly connected to the drive shaft, and multiple second helical gears are arranged in an equidistant array on the first helical gear. The first helical gear meshes with the second helical gears. Each second helical gear is fixedly connected to a lead screw, and one end of the lead screw away from the second helical gear is rotatably connected to the power chamber. A clamping component is provided on one side of the power chamber, and the clamping component includes multiple connecting rods. Each connecting rod passes through the power chamber and is fixedly connected to a screw cap. The screw cap is secured by multiple clamping rods to achieve rotation, and movement is prevented by the squeezing of a pusher block, thus enabling stable cutting.

[0004] However, although the aforementioned clamping device for producing screw fasteners reverses the rotation of the first rotating handle to drive the drive shaft to rotate in reverse, thereby converging multiple connecting rods and clamping rods, and clamping the screw cap by moving the clamping rods in the center, and because the clamping rods are inclined and have toothed stripes, they can achieve a stable clamping effect on the screw cap, there are still the following obvious defects in use: Although the aforementioned clamping device can clamp and fix the screw fasteners for cutting, it can only clamp and cut a single number of fasteners, and cannot simultaneously cut and process multiple screw fasteners and clamping blocks of different shapes, thus affecting the processing progress of the screw fasteners.

At the same time, the servo motor drives the workpiece positioning and placement seat to rotate and use the cutting disc for cutting, thereby realizing continuous cutting of a corresponding number of screw fasteners and further improving the screw fastener processing progress.

[0015] By combining the transverse sliding block, slider, guide bar, telescopic cylinder, slide groove, and base, after cutting the screw fastener, the telescopic cylinder uses the slider to move the transverse sliding block to one side.

[0023] The base 1 has a sliding block 2 at one end that provides a transverse seat 3 for loading and unloading screw fasteners. A servo motor 20 is installed in the inner cavity at the end of the transverse seat 3 to drive the workpiece positioning seat 4 to rotate. The workpiece positioning seat 4 is rotated at the end of the transverse seat 3 to position and press the screw fasteners, so that the screw fasteners are positioned on each side of the end of the workpiece positioning seat 4. Each side of the end of the workpiece positioning seat 4 is uniformly provided with workpiece positioning holes and slots 5 with different shapes and inner diameters, so that the screw fasteners remain stable during movement and cutting.

[0024] L-shaped fixing bracket 6 is installed on one side of the end of the base 1, and the upper part of the L-shaped fixing bracket 6 extends to the vertical upper end of the workpiece positioning and placement seat 4. The lower end face of the top of the L-shaped fixing bracket 6 is provided with a pressure plate 8 for vertically positioning and pressing the screw fastener after rotation by the cylinder 7. The pressure plate 8 is provided with a workpiece positioning through hole 9 that is vertically corresponding to the workpiece positioning slot 5 and passes through it, so that the screw end of the screw fastener can pass through for pressing, so as to facilitate cutting processing.

[0025] A groove 10 is provided on one side of the end of the base 1, allowing the slider 2 to slide in the groove 10. Guide bars 11 are provided on both sides inside the groove 10 to maintain the lateral stability of the slider 2 during sliding. A telescopic cylinder 12 is provided at the center of one side of the groove 10 to push the slider 2 to move inside the groove 10. The slider 2 is slidably positioned inside the groove 10, and the guide bars 11 move through both sides of the slider 2 to guide the slide, allowing the workpiece positioning seat 4 to move laterally. The middle of one side of the slider 2 is fixedly connected to one end of the telescopic cylinder 12. The top of the cylinder 7 is fixed to the upper inside of the L-shaped fixing frame 6, and the bottom of the piston rod of the cylinder 7 is fixedly connected to the center of the end of the pressure plate 8 through a bearing seat. A positioning cylinder 19 is provided through the center of the pressure plate 8, and the top of the positioning cylinder 19 is fixed to the end of the bearing seat, allowing the pressure plate 8 to rotate with the workpiece positioning seat 4 to cut the screw fasteners one by one.

[0026] The workpiece positioning and placement seat 4 has a vertically positioned pressure positioning column 13 at the center of its end, which keeps the pressure plate 8 in a pressed and positioned state during rotation. The workpiece positioning and placement seat 4 has a circular workpiece positioning hole groove 5 with uniform anti-slip protrusions on the inner side to prevent the screw fasteners of the circular brick from sliding. The L-shaped fixing frame 6 has a horizontal cylinder 14 in the middle of its inner side, which pushes the mounting plate 15 to move laterally.

The operator places the corresponding number of rotating block screws of different shapes and inner diameters to be cut and processed into the workpiece positioning slots 5 at the end of the workpiece positioning seat 4, each with a different shape and inner diameter, for vertical positioning. Then, the telescopic cylinder 12 pushes the slider 2 to move towards one side of the base 1 within the slide groove 10, and the workpiece positioning seat 4 moves to one side accordingly. When the slider 2 stops at the end of the slide groove, the workpiece positioning seat 4 is positioned at the vertical bottom of the pressure plate 8. At this time, the cylinder 7 pushes the positioning cylinder 19 downward, and the pressure plate 8 moves downward accordingly, so that the positioning cylinder 19 is positioned on the pressure positioning post 13. At the same time, the fastening screw passes through the workpiece positioning through hole 9 to tighten the screw.

Finally, the transverse cylinder 14 pushes the mounting plate 15 to one side, while simultaneously causing the cutting motor 17 and cutting disc 18 to move down to one side of the screw fastener. The cutting motor 17 drives the cutting disc 18 to rotate, and the servo motor 20 drives the workpiece positioning seat 4 to rotate, using the cutting disc 18 to cut, thereby achieving continuous cutting processing of the fastener. Furthermore, by using the cutting telescopic cylinder 16 to push the cutting motor 17 to adjust its height, fastening screws of different lengths can be processed. After the fastening screws are processed, the telescopic cylinder 12 retracts, causing the transverse moving seat 3 to move to the right on the base 1 to a safe area, so that workers can safely pick up and put away the fastening screws.
