Description

Technical Field

[0001] This invention belongs to the technical field of automotive parts processing, specifically a hole-opening device for the production and processing of car door slide rails. Background Technology

[0002] The door slide rail is a core load-bearing and guiding component in the automotive door system. It is used for door opening and closing operations. Several mounting holes need to be machined on its surface for assembly with the door frame, window lifting mechanism and other components. The machining accuracy and positional consistency of the mounting holes directly affect the smoothness of the door opening and closing and its service life.

[0003] Currently, the industry mostly uses traditional single-station drilling equipment for drilling holes in car door slide rails. The process is usually as follows: a person manually clamps a single slide rail onto a fixture, starts the equipment to complete a single drilling operation, and after stopping the machine, the person manually disassembles the processed slide rail and then clamps the next slide rail to repeat the above operation. This processing method has low processing efficiency and consumes a lot of manpower, which restricts the improvement of overall production capacity. Summary of the Invention

[0004] This invention provides a hole-opening device for manufacturing and processing car door slide rails, which can solve the technical problem that existing hole-opening devices require manual assistance for loading and unloading, resulting in low processing efficiency.

[0005] A hole-opening device for manufacturing and processing car door slide rails includes a base box, a fixed frame is fixedly installed on one side of the top of the base box, a drive mechanism is fixedly installed on one side of the fixed frame, a hole-opening mechanism is connected to the bottom of the drive mechanism, and a through groove is opened inside the base box, and a rotating feeding mechanism is rotatably connected in the through groove. The rotary feeding mechanism includes a roller, and several positioning mechanisms are fixedly installed at equal intervals on the outside of the roller.

[0006] As a further technical solution of the present invention, a rotary motor housing is fixedly installed on the side of the base box away from the fixed frame, and a rotary motor is installed inside the rotary motor housing.

[0007] As a further technical solution of the present invention, a connecting seat is fixedly installed at one end of the roller, the drive shaft of the rotary motor is fixedly connected to the connecting seat, and both ends of the roller are rotatably connected to the two side walls of the through groove.

[0008] As a further technical solution of the present invention, the positioning mechanism includes a fixed box fixedly connected to the roller, a lead screw motor fixedly installed at one end of the fixed box, and a fixed plate fixedly installed at the top of the fixed box away from its end. A lead screw is rotatably installed inside the fixed box, and a transverse plate is fixedly connected to the outside of the lead screw through a ball slider. The lead screw is driven by the lead screw motor. A transverse groove is opened on the fixed box, and multiple folded dustproof curtains are connected between the two sides of the transverse plate and the transverse groove.

[0009] As a further technical solution of the present invention, the driving mechanism includes a vertical driving rail, a horizontal driving rail connected to the outside of the vertical driving rail via a vertical sliding slider, a horizontal sliding slider slidably connected to the outside of the horizontal driving rail, and an opening mechanism fixedly connected to the bottom surface of the horizontal sliding slider.

[0010] As a further technical solution of the present invention, the hole-opening mechanism includes an extension plate fixedly connected to the transverse slider, and a hole-opening motor box is fixedly installed on the bottom surface of the extension plate. Horizontal plates are fixedly installed on both sides of the hole-opening motor box. U-shaped frames are slidably installed on both sides of the hole-opening motor box. The U-shaped frames are located below the horizontal plates, and support plates are fixedly installed on both sides of the U-shaped frames. A spring telescopic rod is fixedly connected between the top of the support plate and the bottom of the horizontal plate. A hole-opening drill rod is fixedly connected to the bottom of the hole-opening motor box, and a through hole is opened through the bottom of the U-shaped frame.

[0011] As a further technical solution of the present invention, the drilling rod is located directly above the through hole, and fixed rails are fixedly installed on both sides of the drilling motor box, with the U-shaped frame slidably connected to the fixed rails.

[0012] As a further technical solution of the present invention, the spring telescopic rod includes a movable end and a fixed end, the movable end is sleeved inside the fixed end, and a spring is connected between the bottom of the movable end and the inner bottom end of the fixed end.

[0013] As a further technical solution of the present invention, a feeding mechanism is also installed in the bottom box. The feeding mechanism includes a telescopic cylinder. A connecting plate is fixedly connected to the end of the telescopic cylinder. An electromagnetic suction plate is provided at the bottom of the connecting plate. An electric push rod is embedded inside the connecting plate. The driving end of the electric push rod faces downward and is fixedly connected to the top surface of the electromagnetic suction plate.

[0014] As a further technical solution of the present invention, the telescopic cylinder is fixedly installed at the front of the bottom box, the connecting plate is located below the roller, the rear of the bottom box is provided with a discharge chute communicating with the through groove, and a conveyor belt is fixedly installed in the discharge chute. One end of the conveyor belt is located inside the bottom box and directly below the electromagnetic suction plate.

[0015] The beneficial effects of the present invention are as follows: The present invention sets up a rotary feeding mechanism and sets up multiple positioning mechanisms on the roller. By utilizing the rotation of the roller, after the hole is opened on one slide rail, the next slide rail can be quickly moved to the bottom of the hole opening mechanism for hole opening through the rotation of the roller. There is no need to stop the machine, saving the manual continuous feeding operation and effectively improving the processing efficiency. Furthermore, after the slide rail is fixed by the positioning mechanism, when the hole is drilled, as the drilling mechanism moves downward, the U-shaped frame contacts the top surface of the slide rail. After it continues to move downward, the spring telescopic rod is compressed, and the U-shaped frame presses the end face of the hole, thereby further reinforcing the slide rail. This allows the slide rail to maintain good stability during the drilling process and effectively ensures the drilling quality. By setting up a feeding mechanism, the telescopic cylinder extends through its telescopic end, causing the electromagnetic suction plate to contact and adhere to the perforated slide rail. At this point, the transverse plate is moved away, so that the slide rail is no longer clamped. Then, the electric push rod is moved down to place the slide rail on the conveyor belt, thereby realizing the discharge operation. By continuously rotating the roller, multiple perforated slide rails are transferred to the conveyor belt and transported out, eliminating manual feeding operations, realizing batch feeding processing, and further improving processing efficiency.

[0018] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-5 As shown, a hole-opening device for manufacturing and processing car door slide rails includes a base box 1. A fixing frame 7 is fixedly installed on one side of the top of the base box 1. A drive mechanism is fixedly installed on one side of the fixing frame 7. A hole-opening mechanism 10 is connected to the bottom of the drive mechanism. A through groove 2 is opened inside the base box 1, and a rotating feeding mechanism 3 is rotatably connected inside the through groove 2. The rotary feeding mechanism 3 includes a roller 31, and several positioning mechanisms 33 are fixedly installed at equal intervals on the outside of the roller 31.

[0020] Specifically, multiple slide rails are positioned and fixed by several positioning mechanisms 33, and the rotation of the roller 31 is used to rotate different slide rails to the top of the opening mechanism 10 for opening operation, thereby realizing the rapid switching operation when opening multiple slide rails.

[0021] A rotary motor housing 4 is fixedly installed on the side of the base box 1 away from the fixed frame 7. A rotary motor is installed inside the rotary motor housing 4. A connecting seat 32 is fixedly installed on one end of the roller 31. The drive shaft of the rotary motor is fixedly connected to the connecting seat 32, and both ends of the roller 31 are rotatably connected to the two side walls of the through groove 2.

[0022] Specifically, the rotation of the roller 31 is achieved by driving the rotary motor to rotate, thereby enabling the switching of the orientation of multiple fixed slide rails and thus enabling the opening operation of multiple slide rails.

[0023] The positioning mechanism 33 includes a fixed box 331 fixedly connected to the roller 31. A lead screw motor 332 is fixedly installed at one end of the fixed box 331, and a fixed plate 333 is fixedly installed at the top of the fixed box 331 away from its end. A lead screw is rotatably installed inside the fixed box 331. A transverse plate 334 is fixedly connected to the outside of the lead screw through a ball slider. The lead screw is driven by the lead screw motor 332. A transverse groove is opened on the fixed box 331. Multiple folded dustproof curtains 335 are connected between the two sides of the transverse plate 334 and the transverse groove.

[0024] Specifically, the slide rail is placed on top of the fixed box 331, with one end attached to the fixed plate 333. The lead screw motor 332 drives the lead screw to rotate, and then the ball slider moves on its surface to move the transverse plate 334 to abut against the other end of the slide rail, thereby fixing the slide rail on top of the fixed box 331 and realizing the positioning operation of the slide rail. This ensures that the slide rail remains stable when the hole is opened, thus facilitating the opening operation. As the transverse plate 334 moves, the dust curtain 335 adaptively retracts, always blocking the surface of the transverse groove, thereby preventing debris generated during the opening from entering the fixed box 331 and damaging the lead screw.

[0025] The driving mechanism includes a vertical driving rail 8, a horizontal driving rail 9 connected to the outside of the vertical driving rail 8 via a vertical sliding slider, a horizontal sliding slider slidably connected to the outside of the horizontal driving rail 9, and an opening mechanism 10 fixedly connected to the bottom surface of the horizontal sliding slider.

[0026] Specifically, by setting the vertical drive rail 8, the horizontal drive rail 9 can be moved up and down, thereby adjusting the height of the opening mechanism 10. The horizontal drive rail 9 can also drive the opening mechanism 10 to move laterally, thereby adjusting its lateral position.

[0027] The drilling mechanism 10 includes an extension plate 102 fixedly connected to a horizontal sliding block. A drilling motor housing 101 is fixedly mounted on the bottom surface of the extension plate 102. Horizontal plates 103 are fixedly mounted on both sides of the drilling motor housing 101. U-shaped frames 104 are slidably mounted on both sides of the drilling motor housing 101, located below the horizontal plates 103. Support plates 108 are fixedly mounted on both sides of the U-shaped frames 104. A spring telescopic rod 105 is fixedly connected between the top of the support plate 108 and the bottom of the horizontal plate 103. A drilling drill rod 106 is fixedly connected to the bottom of the drilling motor housing 101. A through hole 107 is drilled through the bottom of the U-shaped frame 104. The drilling drill rod 106 is located directly above the through hole 107. Fixed rails are fixedly mounted on both sides of the drilling motor housing 101, and the U-shaped frame 104 is slidably connected to the fixed rails. Specifically, as the hole-opening mechanism 10 moves downward, the U-shaped frame 104 first contacts the top surface of the slide rail. After it continues to move downward, the spring telescopic rod 105 is compressed, and the U-shaped frame 104 presses the hole-opening end face. Then, the hole-opening drill rod 106 continues to rotate and contacts the surface of the slide rail to realize the hole-opening operation.

[0028] The spring telescopic rod 105 includes a movable end and a fixed end. The movable end is sleeved inside the fixed end, and a spring is connected between the bottom of the movable end and the bottom of the fixed end.

[0029] Specifically, after the spring telescopic rod 105 is compressed, the spring contracts. After the entire opening mechanism 10 is reset, the U-shaped frame 104 can also be reset under the action of the spring's rebound force.

[0030] The bottom box 1 is also equipped with a feeding mechanism 6. The feeding mechanism 6 includes a telescopic cylinder 61. The end of the telescopic end 62 of the telescopic cylinder 61 is fixedly connected to a connecting plate 63. An electromagnetic suction plate 64 is provided at the bottom of the connecting plate 63. An electric push rod 65 is embedded inside the connecting plate 63. The driving end of the electric push rod 65 faces downward and is fixedly connected to the top surface of the electromagnetic suction plate 64.

[0031] Telescopic cylinder 61 is fixedly installed at the front of the base box 1, connecting plate 63 is located below roller 31, and a discharge chute communicating with through groove 2 is opened at the rear of the base box 1. A conveyor belt 5 is fixedly installed in the discharge chute, and one end of the conveyor belt 5 is located inside the base box 1 and directly below the electromagnetic suction plate 64.

[0032] Specifically, the telescopic cylinder 61 extends through the telescopic end 62, causing the electromagnetic suction plate 64 to contact and adhere to the slide rail after the opening. Then, the electric push rod 65 moves down to place the slide rail on the conveyor belt 5, thereby realizing the material discharge operation.

[0033] This invention discloses a hole-opening device for manufacturing and processing car door slide rails. In use, multiple car door slide rails are first assembled sequentially with each positioning mechanism 33. A rotary motor drives a roller 31 to rotate continuously, switching the position of the positioning mechanism 33. During assembly, the car door slide rail is placed on a fixed box 331, with one end of it in contact with a fixed plate 333. A lead screw motor 332 drives a lead screw to rotate, and then a ball bearing slider moves on its surface, causing a transverse plate 334 to move until it abuts against the other end of the slide rail, thereby fixing the slide rail to the top of the fixed box 331 and realizing the positioning operation of the slide rail.

[0034] Next, the assembled door slide rail is drilled. Driven by the vertical drive rail 8, the horizontal drive rail 9 can move up and down, thereby adjusting the height of the drilling mechanism 10. After the horizontal drive rail 9 is driven, the drilling mechanism 10 can move laterally, thereby adjusting the lateral position, so that the drilling rod 106 can drill holes at different positions of the slide rail.

[0035] As the drilling mechanism 10 moves downward, the U-shaped frame 104 first contacts the top surface of the slide rail. After moving downward, the spring telescopic rod 105 is compressed, and the U-shaped frame 104 presses the drilling end face tightly. Then, the drilling rod 106 rotates continuously and contacts the surface of the slide rail to realize the drilling operation. After the drilling is completed, the drilling mechanism 10 is moved upward, and the U-shaped frame 104 is reset under the action of the spring rebound force, so that the drilling operation at the next position can continue.

[0036] After all the slide rail opening operations are completed, the roller 31 is rotated to keep the slide rail continuously aligned with the feeding mechanism 6. The telescopic cylinder 61 extends through the telescopic end 62, causing the electromagnetic suction plate 64 to contact and attract the opened slide rail. At this time, the transverse plate 334 is moved away so that the slide rail is no longer clamped. Then, the electric push rod 65 is moved down to place the slide rail on the conveyor belt 5, thereby realizing the discharge operation. By continuously rotating the roller 31, multiple opened slide rails are transferred to the conveyor belt 5 and transported outward.

[0037] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
