Description

Technical Field

[0001] The utility model relates to the technical field of gasket processing, in particular to a gasket drilling and forming device. Background Art

[0002] Washers are parts placed between the connected parts and nuts. They are usually flat metal rings that protect the surface of the connected parts from being scratched by the nuts and disperse the pressure of the nuts on the connected parts. Washers are usually made of metal and have a hole in the middle that matches the size of the stud. Therefore, it is necessary to drill holes inside the washers during processing.

[0003] In the existing technology, when processing holes on washers, when the washers are moved to the processing position, they need to be driven by electric push rods or hydraulic cylinders to be positioned at the specified position before the drilling process is carried out. During this process, additional driving equipment is required to clamp the workpiece, which increases the cost of the equipment. Utility Model Content

[0004] The utility model aims to provide a drilling and forming device for a gasket to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a gasket drilling and forming device, comprising a machine platform,

[0006] A stand is installed on the top of the machine platform, and a hydraulic cylinder is installed on the top of the stand. The output shaft of the hydraulic cylinder is connected to a lifting plate downward, and a drilling portion is installed at the bottom of the lifting plate. Both sides of the lifting plate penetrate to the outside of the stand, and both sides of the lifting plate are respectively inserted into a lifting frame. A rack is fixedly connected to the bottom of the lifting frame, and the bottom of the rack penetrates to the bottom of the machine platform.

[0007] Four mounting seats are installed at the same horizontal position on both sides of the bottom of the machine, and a screw rod is rotatably installed between the mounting seats on the same side. A gear is installed at the end of the mounting seat away from the middle, and the gear is meshed with the rack. A slider is threadedly connected to the screw rod, and the top of the slider passes through the top of the machine and is connected to the clamping plate.

[0008] By adopting the above technical solution, when in use, after the workpiece moves to the bottom of the drilling part, the hydraulic cylinder drives the lifting plate and the drilling part to descend as a whole, and when the lifting plate descends, it drives the lifting frame and the rack to move downward, and the rack drives the gear to rotate, so that the screw rod drives the slider to move horizontally, thereby driving the clamping plate to clamp the workpiece. After clamping, the lifting plate and the drilling part continue to move downward to drill the workpiece.

[0009] As a further solution of the utility model: the machine platform includes a through hole 1, a through hole 1 is opened on both sides of the machine platform at positions aligned with the rack, a through groove is opened on both sides of the machine platform at positions aligned with the screw rod, a through hole 2 is opened on the machine platform at a position aligned with the drilling part, and two forward and backward conveyor belts are installed on the top of the machine platform, and the conveyor belts are respectively located on both sides of through hole 2.

[0010] By adopting the above technical solution, the design of through hole one facilitates the lifting and lowering of the rack, the design of the through slot facilitates the lateral movement of the slider and the clamping plate, the design of through hole two facilitates the drilling of the workpiece, and the conveyor belt can transport the workpiece to the specified position.

[0011] As a further solution of the utility model: the cross-section of the second through hole is an inverted isosceles trapezoid, and a collecting box is installed at the bottom of the machine in a position aligned with the second through hole.

[0012] By adopting the above technical solution, when in use, the drilling part can drill a hole in the workpiece through the second through hole, and the collection box can cooperate with the second through hole to collect the debris drilled during processing.

[0013] As a further solution of the utility model: the lifting frame includes a lifting slot, a lifting slot matching the lifting plate is opened in the lifting frame, and a vertical spring 1 is installed at the bottom of the lifting slot, and the top of the spring 1 is connected to the bottom of the lifting plate.

[0014] By adopting the above technical solution, when in use, after the clamp has clamped the workpiece, the sliders and clamps on both sides cannot continue to approach each other, so the screw rod and the gear cannot continue to rotate, and then the lifting frame and the rack cannot continue to move downward. At this time, the lifting plate continues to move downward in the lifting frame to squeeze the spring 1, so as to facilitate the continued downward movement of the drilling part and drill the clamped and positioned workpiece.

[0015] As a further solution of the utility model: a telescopic slot is provided at the upper position of the inner wall of the lifting slot, and a clamping block is installed in the telescopic slot through a second spring, and a clamping slot matching the clamping block is provided on the side wall of the lifting plate.

[0016] By adopting the above technical solution, when not clamped, the card block is located in the card slot, so that the lifting plate and the lifting frame can be lifted and lowered synchronously. After clamping, the card block in the lifting plate is separated from the card slot, and the lifting plate is lifted and lowered in the lifting frame.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the drilling and forming device of the gasket is

[0018] A lifting frame, a rack, a lead screw and a gear are provided. When the hydraulic cylinder drives the lifting plate and the drilling part to move downward, the lifting plate drives the lifting frame and the rack to move downward. When the rack moves downward, it drives the gear to rotate, and then the lead screw rotates synchronously to drive the slider and the clamping plate to move horizontally to clamp the workpiece, thereby clamping the workpiece before processing, reducing the use of output equipment and reducing the cost of equipment;

[0019] In addition, the drilling and forming device of the gasket is also provided with a lifting frame. When the workpiece is clamped, the sliders and clamping plates on both sides cannot continue to approach each other, resulting in the screw rod and the gear being unable to continue to rotate, and then the lifting frame and the rack being unable to continue to move downward. At this time, the lifting plate continues to move downward in the lifting frame to squeeze spring one, and causes the clamping block to disengage from the clamping slot and squeeze spring two. This design enables the device to still clamp well when clamping workpieces of different widths, and the downward movement of the drilling part will not be affected by the clamping.

[0028] Specifically, a control panel is installed on the outside of the machine 1 for controlling the coordination of components in the device. The clamping plate 12 is designed in an arc shape to facilitate guiding the workpiece to the middle position.

[0029] See also Figure 3 Furthermore, the machine 1 includes a through hole 101, a through hole 101 is opened on both sides of the machine 1 at positions aligned with the rack 7, a through groove 102 is opened on both sides of the machine 1 at positions aligned with the screw rod 9, a through hole 2 103 is opened on the machine 1 at a position aligned with the drilling part 5, and two forward and backward conveyor belts 13 are installed on the top of the machine 1, and the conveyor belts 13 are respectively located on both sides of the through hole 2 103.

[0030] See also Figure 1 and Figure 3 , further, the cross section of the second through hole 103 is an inverted isosceles trapezoid, and a collection box is installed at the bottom of the machine 1 in alignment with the second through hole 103;

[0031] Specifically, a negative pressure generating mechanism may be installed on the collection box to attract the entry of debris, and a filter is designed at the connection between the collection box and the negative pressure generating mechanism to prevent debris from entering the negative pressure generating mechanism.

[0034] Working principle: When the drilling and forming device of the gasket is used, when the hydraulic cylinder 3 drives the lifting plate 4 and the drilling part 5 to move downward, the lifting plate 4 drives the lifting frame 6 and the rack 7 to move downward. When the rack 7 moves downward, it drives the gear 11 to rotate, and then the screw rod 9 rotates synchronously to drive the slider 10 and the clamping plate 12 to move horizontally to clamp the workpiece, thereby achieving the clamping of the workpiece before processing, reducing the use of output equipment, and reducing the cost of equipment. When the workpiece is clamped, the sliders 10 and the clamping plates 12 on both sides cannot continue to approach each other, resulting in the screw rod 9 and the gear 11 being unable to continue to rotate, and then the lifting frame 6 and the rack 7 being unable to continue to move downward. At this time, the lifting plate 4 continues to move downward in the lifting frame 6 to squeeze the spring 1 602, and the block 605 is disengaged from the slot 401 and squeezes the spring 2 604. This design enables the device to still be able to clamp workpieces of different widths well, and the downward movement of the drilling part 5 will not be affected by the clamping.
