Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to an automatic tapping device for plate parts. Background Technology

[0002] In the mass production of parts, manufacturers generally produce parts by means of molds or stamping, especially for parts such as metal sheets, which are usually produced in batches by stamping. After being stamped, these parts will undergo multiple post-processing operations, such as drilling, tapping, and grinding.

[0003] During the tapping process, workers typically place the stamped sheet on the worktable of a vertical tapping machine. The worktable is equipped with a positioning device to position the sheet. Then, the tapping machine is started, and the tapping machine taps the sheet. After tapping is complete, the worker puts the tapped sheet on the worktable into the material box and then places a new sheet on it. Because the tapping process is very short, workers need to continuously load and unload materials during the work process, resulting in extremely high labor intensity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic tapping device for sheet metal, which solves the problems of short tapping processes, constant loading and unloading of materials, and extremely high labor intensity in existing technologies.

[0005] According to an embodiment of this utility model, an automatic tapping device for plates includes a machine base, a mounting frame, a positioning block, and a discharge shell. A tapping machine is provided on the top of the machine base. The mounting frame is fixedly installed on the top of the machine base. A fixed seat is fixedly installed at one end of the top of the mounting frame, and a guide rail is provided at the other end of the top of the mounting frame. A sliding seat is slidably installed on the guide rail. The mounting frame is also provided with a driving component for driving the sliding seat to move. Several support rods for supporting plates are provided on the opposite sides of the fixed seat and the sliding seat. Mounting slots are provided on both the fixed seat and the sliding seat. A cylinder is provided in each mounting slot. A clamping block is provided on the output end of each cylinder. The positioning block is provided on the opposite sides of the fixed seat and the movable seat. The discharge shell is inclinedly installed on the mounting frame, and the high end of the discharge shell is located between the fixed seat and the movable seat.

[0006] Compared with the prior art, this utility model has the following advantages: By setting a mounting frame on one side of the tapping machine, the drive component on the mounting frame drives the sliding seat to move and change the distance between the sliding seat and the fixed seat. After the plate placed on the support rod is clamped and fixed by the clamping block driven by the cylinder, the tapping machine can perform tapping operation on it. After the plate is processed, the drive component drives the sliding seat away from the fixed seat, so that the plate falls from the support rod into the discharge shell and is discharged to the predetermined position for collection. By adjusting the distance between the sliding seat and the fixed seat, the support and unloading of the plate can be realized. During the operation, the worker only needs to perform the loading operation of the plate and does not need to manually unload the plate, which reduces the labor intensity.

[0007] Furthermore, several threaded holes are provided on the opposite sides of the fixed seat and the sliding seat, and each support rod is screwed into the threaded hole.

[0008] Furthermore, the drive assembly includes: a motor, which is fixedly mounted on the top of the mounting bracket at one end away from the fixed seat; a lead screw is horizontally and rotatably mounted on the mounting bracket, the lead screw is threadedly connected to the sliding seat, and one end of the lead screw is fixedly connected to the output end of the motor.

[0009] Furthermore, it also includes a material collection frame, which is set at the lower end of the discharge shell. The discharge shell includes an outer frame and an inner frame, with the inner frame set inside the outer frame. Several slag discharge holes are opened at the bottom of the inner frame.

[0010] Furthermore, the outer frame has symmetrical slots on its side walls, and the inner frame has two symmetrical lugs on its outer walls, with the slots for the lugs to engage.

[0011] Furthermore, protective pads are provided on the inner wall of the inner frame.

[0012] Furthermore, a limiting plate is provided at the bottom of the discharge shell, and one side of the limiting plate abuts against the outer wall of the outer frame.

[0013] Furthermore, the mounting frame includes: a base plate, with columns at the four corners of the top of the base plate, a top plate on the top of the columns, and a material drop chute on the top plate. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 4As shown in the figure, this utility model embodiment proposes an automatic tapping device for plates, including a machine base 1, a mounting frame 3, a positioning block 10, and a discharge shell 11. A tapping machine 2 is provided on the top of the machine base 1. The mounting frame 3 is fixedly installed on the top of the machine base 1. A fixed seat 4 is fixedly installed at one end of the top of the mounting frame 3. A guide rail 5 is provided on the other end of the top of the mounting frame 3. A sliding seat 6 is slidably installed on the guide rail 5. The mounting frame 3 is also provided with a driving component for driving the sliding seat 6 to move. Several support rods 7 for supporting plates are provided on the opposite sides of the fixed seat 4 and the sliding seat 6. Mounting slots are opened on both the fixed seat 4 and the sliding seat 6. A cylinder 8 is provided in each mounting slot. A clamping block 9 is provided on the output end of each cylinder 8. The positioning block 10 is provided on the opposite sides of the fixed seat 4 and the movable seat. The discharge shell 11 is inclinedly installed on the mounting frame 3. The high end of the discharge shell 11 is located between the fixed seat 4 and the movable seat. Specifically, the mounting frame 3 is located on one side of the machine base 1, and the middle of the mounting frame 3 is connected to the discharge shell 11. The tapping machine 2 is existing technology. The tap at the output end of the tapping machine 2 can be adjusted in height, distance, and other directions to adapt to the tapping requirements of different positions on the plate. When tapping a predetermined position on the plate, the device is first debugged. According to the size of the plate, the drive assembly is started. The drive assembly drives the sliding seat 6 to move. The distance between the fixed seat 4 and the sliding seat 6 is adjusted so that the support rod 7 on the fixed seat 4 and the movable seat can support both ends of the plate respectively. In this embodiment, the positioning block 10 is located on the side of the fixed seat 4 and the sliding seat 6 away from the worker, so the plate The side of the workpiece away from the worker abuts against the side wall of the positioning block 10, which facilitates the positioning requirements in batch processing. When tapping, the cylinders 8 on the fixed seat 4 and the movable seat are activated at the same time. The two cylinders 8 push the clamping block 9 closer to each other to clamp the workpiece. Then the tapping machine 2 is activated. The tapping machine 2 taps the predetermined position of the workpiece. After tapping is completed, the tapping machine 2 returns to the zero position, and the two cylinders 8 release the workpiece. At this time, the sliding seat 6 moves away from the fixed seat 4. Since the sliding seat 6 will drive the support rod 7 on it to move, when the workpiece loses its support, the workpiece falls into the discharge shell 11 and is guided to the predetermined position by the tilted discharge shell 11. In a preferred embodiment, the clamping block 9 is located within the mounting groove. When the sliding seat 6 moves away from the fixed seat 4, the cylinder 8 on the fixed seat 4 and / or the sliding seat 6 is activated again, pushing the clamping block 9 out of the mounting groove. This prevents the plate from falling into the discharge shell 11 when the plate is small, as the support rod 7 on one side can support the plate. With this device, when tapping the plate, the worker only needs to perform the loading action, and the plate can be automatically unloaded after processing, significantly reducing the labor intensity of the worker.

[0022] Furthermore, the fixed seat 4 and the sliding seat 6 are provided with several threaded holes on their opposite sides, and each support rod 7 is screwed into the threaded hole. The support rod 7 is detachably connected to the corresponding fixed seat 4 or sliding seat 6 by means of screwing. In actual production, the positions on the plate that need to be tapped are generally located at both ends of the plate. Due to the detachability of the support rod 7, by installing any number of support rods 7 and removing the support rod 7 directly below the position that needs to be tapped, the plate can be supported while preventing the tap on the tapping machine 2 from drilling into the support rod 7.

[0023] like Figure 5 As shown, the driving component further includes: a motor 12, which is fixedly mounted on the top of the mounting frame 3 at the end away from the fixed seat 4; a lead screw 13 is horizontally and rotatably mounted on the mounting frame 3, and the lead screw 13 is threadedly connected to the sliding seat 6; one end of the lead screw 13 is fixedly connected to the output end of the motor 12. Specifically, in this embodiment, two mounting plates are symmetrically arranged on the mounting frame 3, and the lead screw 13 is rotatably mounted between the two mounting plates. The bottom of the sliding seat 6 protrudes downward to form a slider, which is slidably mounted on the mounting frame 3 and threadedly connected to the lead screw 13. By starting the motor 12, the lead screw 13 is driven to rotate, and the lead screw 13 drives the sliding seat 6, which is threadedly connected to it, to move, thereby adjusting the distance between the sliding seat 6 and the fixed seat 4. This allows the two to support the plate when they are close together and to unload the plate when they are far apart.

[0024] like Figures 1 to 4 As shown, it further includes a collection frame, which is located at the lower end of the discharge shell 11. The discharge shell 11 includes an outer frame 14 and an inner frame 15, with the inner frame 15 located inside the outer frame 14. The bottom of the inner frame 15 has several slag discharge holes. By placing the collection frame at the lower end of the discharge shell 11, the processed plates slide from the discharge shell 11 into the inner frame 15. The debris generated during the tapping process enters the inner frame 15 and is then dropped from the slag discharge holes of the inner frame 15 into the outer frame 14 for separate processing, thereby avoiding the collection of too many impurities in the piles of plates.

[0025] like Figure 4 As shown, furthermore, the outer frame 14 has symmetrical slots on its side walls, and the inner frame 15 has two symmetrical lugs 16 on its outer walls. The slots allow the lugs 16 to engage. The inner frame 15 is engaged with the outer frame 14 via the lugs 16, forming a space between the bottom of the outer frame 14 and the inner frame 15 for holding debris. After the inner frame 15 has stored a certain number of plates, the worker can use both hands to hold the two lugs 16 and move the inner frame 15 to a predetermined position.

[0026] like Figure 4As shown, a protective pad 17 is further provided on the inner wall of the inner frame 15. By providing the protective pad 17, when the plate slides down from the high end of the discharge shell 11 and impacts the inner wall of the inner frame 15, the protective pad 17 plays a protective role, preventing the plate from deforming during the impact.

[0027] like Figure 1 and Figure 2 As shown, furthermore, a limiting plate 18 is provided at the bottom of the discharge shell 11, and one side of the limiting plate 18 abuts against the outer wall of the outer frame 14. One end of the discharge shell 11 rests on the mounting bracket 3, and the other end abuts against the outer wall of the outer frame 14 through the limiting plate 18, which can prevent the discharge shell 11 from sliding down. The discharge shell 11 can also be connected to the mounting bracket 3 by screws.

[0028] like Figure 1 and Figure 2 As shown, the mounting frame 3 further includes: a base plate 301, with columns 302 at each of the four corners of the top of the base plate 301, and a top plate 303 mounted on the top of the columns 302. A material drop chute is provided on the top plate 303. In this embodiment, the structure of the mounting frame 3 is specifically disclosed. The base plate 301 is fixed to the machine base 1, the fixed seat 4 is fixedly mounted on the top plate 303, the guide rail 5 is also mounted on the top plate 303, the sliding seat 6 slides on the guide rail 5, and the plate can fall into the discharge shell 11 through the material drop chute.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
