Description

Technical Field

[0001] This invention relates to the field of sheet metal processing equipment technology, and more specifically to a drilling device for sheet metal parts. Background Technology

[0002] During the assembly process, sheet metal can be connected to other parts in various ways. Among them, the most common methods are welding and bolting. Since welding is a non-removable connection method, bolting is more widely used than welding.

[0003] In the manufacturing process of some equipment, the assembly precision requirements between sheet metal parts are relatively high. Therefore, the precision requirements for holes on sheet metal parts are also relatively high during sheet metal processing.

[0004] Because sheet metal has a large surface area, ordinary drilling machines cannot meet production requirements. For example, it is difficult to drill holes in the center of the sheet metal, and when drilling holes on different sides of the sheet metal, the sheet metal needs to be moved. Summary of the Invention

[0005] To address the technical problem that conventional drilling machines are insufficient for processing large-area sheet metal, this invention provides a drilling device for sheet metal parts, which has the advantage of being able to precisely drill holes at any position after the sheet metal is fixed.

[0009] Two support rods are vertically slidably mounted on the lower track.

[0010] The suspension is slidably mounted on the upper track, and the suspension is located above the two support rods;

[0011] The top of the suspended basket is slidably connected to the suspension frame, and a drill bit is provided at the bottom of the suspended basket, with the drill bit facing the gap between the two support rods.

[0012] A drive mechanism having an output end connected to the support rod and the suspension for driving the support rod and the suspension to slide on the carriage;

[0013] The lower track has an L-shaped positioning plate at one end.

[0016] A connecting plate, the top end of which is fixedly connected to one end of the suspension, the bottom end of which is fixedly connected to one end of the support rod, and a threaded hole in the middle of the connecting plate;

[0017] A drive motor, the output shaft of which is coaxially connected to the end of a drive screw, and the drive screw engages with a threaded hole on the connecting plate;

[0018] The drive screw is parallel to the upper track, and the drive motor is located at one end of the carriage.

[0019] Optionally, the carriage includes two parallel lower rails, and a through groove is provided in the middle of the lower rails, the through groove being arranged along the length direction of the lower rails;

[0020] The two ends of the support rod pass through the through slots on the two lower tracks respectively, and the middle part of the support rod protrudes and is flush with the top surface of the two lower tracks.

[0021] Optionally, two suspensions are arranged parallel to each other, and a groove is provided in the middle of the suspension along its length. The basket is slidably disposed in the two grooves, and a power mechanism for driving the basket to slide is provided on the suspension.

[0022] Optionally, the power mechanism includes:

[0023] Two guide wheels are respectively located at both ends of the suspension;

[0024] A drive chain is fitted onto the two guide wheels, and the drive chain is fixedly connected to the suspended platform.

[0025] The power motor has its output shaft connected to the drive chain.

[0026] Optionally, it also includes:

[0027] A pressing component is located at the end of the basket away from the suspension, and the bottom of the pressing component has a movable pressing end.

[0028] Optionally, the pressing component includes:

[0029] A support plate, located below the suspended basket, has one end connected to a drilling device for driving the drill bit down, and has a sliding hole in the middle of the support plate;

[0030] A sliding rod is slidably disposed within the sliding hole;

[0031] Two limiting plates are respectively installed at both ends of the slide rod;

[0032] A spring is sleeved on the slide rod and located between the limiting plate and the support plate, with the spring positioned below the support plate.

[0033] Optionally, a pressing component is provided on each side of the drilling equipment, and the pressing ends of the two pressing components are directly opposite the gap between the two support rods.

A drive mechanism drives the support rods and suspension to move synchronously, ensuring that the stamping end is always aligned with the gap between the two support rods.

[0037] Because the basket is slidably mounted on the suspension, the position of the drill bit above the entire lower track can be adjusted arbitrarily.

[0038] Additionally, an L-shaped positioning plate is installed at the end of the lower track. When the sheet metal to be processed is placed on the lower track, one corner can be positioned inside the positioning plate for positioning. Furthermore, the support rod and the lower track form a support structure for the sheet metal, preventing it from collapsing in the middle.

[0039] In this technical solution, once the sheet metal to be processed is positioned, the purpose of drilling holes at any position can be achieved. Attached Figure Description

[0055] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

They are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0057] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Example

[0058] See Figures 1-3 A drilling device for sheet metal parts includes a frame 10, a carriage, a support rod 21, a suspension 31, a basket 32, a drill bit 33, and a drive mechanism 40. The carriage includes two parallel upper rails 34 and two parallel lower rails 22.

[0059] Specifically, the upper track 34 is located above the lower track 22, and the upper track 34 and the lower track 22 are parallel to each other. The two upper tracks 34 are on the same plane, and the two lower tracks 22 are on another plane, with the distance between the two upper tracks 34 being greater than the distance between the two lower tracks 22. Both the upper track 34 and the lower track 22 are mounted on the frame 10, which is a frame structure.

[0060] One end of one of the lower tracks 22 has an L-shaped positioning plate 23. The positioning plate 23 protrudes relative to the top surface of the lower track 22, and one end of the positioning plate 23 points to the other end of the lower track 22, while the other end of the positioning plate 23 points to another lower track 22.

[0061] There are two support rods 21, with each end of the support rod 21 slidably connected to one of the two lower rails 22. The two support rods 21 are arranged parallel to each other, and there is a gap between them. In addition, the top surface of the support rod 21 is on the same plane as the top surface of the lower rail 22.

[0062] Two suspensions 31 are provided between the two upper rails 34, and the two suspensions 31 are located directly above the two support rods 21.

[0063] The top of the suspended basket 32 ​​is slidably disposed between two suspensions 31, and the bottom of the suspended basket 32 ​​is vertically downward disposed, with a drill bit 33 disposed at the bottom, wherein the drill bit 33 is directly opposite the gap between the two support rods 21.

[0064] The drive mechanism 40 has an output end that connects two support rods 21 and two suspensions 31 simultaneously. The output end of the drive mechanism 40 is used to drive the support rods 21 to slide on the lower track 22 and to drive the two suspensions 31 to slide on the upper track 34.

[0065] The working principle of this embodiment is as follows: two support rods 21 are slidably arranged on the lower track 22, and a suspension 31 is slidably arranged on the upper track 34. The drill bit 33 is arranged at the bottom of the basket 32, and the basket 32 ​​is slidably arranged on the suspension 31. The support rods 21 and the suspension 31 are driven to move synchronously by the drive mechanism 40, so that the stamping end is always aligned with the gap between the two support rods 21.

[0066] Since the basket 32 ​​is slidably mounted on the suspension 31, the position of the drill bit 33 above the entire lower track 22 can be adjusted arbitrarily.

[0067] In addition, an L-shaped positioning plate 23 is provided at the end of the lower track 22. When the sheet metal to be processed is placed on the lower track 22, one corner of the sheet metal can be placed inside the positioning plate 23 for positioning. Furthermore, the support rod 21 and the lower track 22 can form a support structure for the sheet metal, preventing the middle part from collapsing.

[0068] In this technical solution, once the sheet metal to be processed is positioned, the purpose of drilling holes at any position can be achieved.

[0069] In one specific embodiment:

[0070] The drive mechanism 40 includes a connecting plate 41, a drive motor 42, and a drive screw 43. The connecting plate 41 is vertically disposed on the side of the suspension 31. The top end of the connecting plate 41 is fixedly connected to one end of the two suspensions 31, and the bottom end of the connecting plate 41 is fixedly connected to one end of the two support rods 21. The connecting plate 41 has a threaded hole in the middle.

[0071] The drive motor 42 is located at one end of the carriage and is mounted on the frame 10. The output shaft of the drive motor 42 is fixedly connected to one end of the drive screw 43, the drive screw 43 matches the threaded hole on the connecting plate 41, and the other end of the drive screw 43 is rotatably connected to the frame 10.

[0072] The connecting plate 41 is the output end of the drive mechanism 40.

[0073] In this embodiment, the drive screw 43 is rotated by the drive motor 42, and the drive screw 43 causes the suspension 31 and the support rod 21 to move in the carriage through the connecting plate 41.

[0074] In another specific embodiment:

[0075] See Figure 6 The lower track 22 has a through groove 24 in the middle, which is arranged along its length. The through grooves 24 on the two lower tracks 22 are arranged opposite to each other. The two ends of the support rod 21 pass through the channels on the two lower tracks 22 respectively, and the middle part of the support rod 21 protrudes upward, so that the top surface of the middle part of the support rod 21 is flush with the top surface of the lower track 22.

[0076] The suspension 31 has a groove 35 in its middle section, which runs along its length. The grooves 35 on the two suspensions 31 are arranged opposite each other. The top sides of the basket 32 ​​are slidably disposed within the two grooves 35. A base plate 36 is disposed between the two suspensions 31 above the grooves 35. A power mechanism 50 is disposed on the base plate 36, which is used to drive the basket 32 ​​to move back and forth within the grooves 35.

[0077] In this embodiment, by setting the middle part of the support rod 21 as a protruding structure, the bottom surface of the sheet metal to be processed can be supported by the support rod 21.

[0078] In another specific embodiment:

[0079] See Figures 1-4 The power mechanism 50 includes a guide wheel 51, a drive chain 52, and a power motor 53. Specifically, the power motor 53 is fixedly mounted on the base plate 36, and a drive wheel 54 is provided at each end of the power motor 53, with the two drive wheels 54 located above the two suspensions 31 respectively.

[0080] Each of the two suspensions 31 has a guide wheel 51 rotatably mounted at both ends, the diameter of which is larger than the thickness of the suspension 31. A drive chain 52 is fitted onto the two guide wheels 51 located on the same suspension 31, and the drive chain 52 is also wound around a drive wheel 54 above the suspension 31. Each of the two suspensions 31 has a drive chain 52.

[0081] Among them, the drive wheel 54 and the guide wheel 51 are sprockets.

[0082] The aforementioned basket 32 ​​has a rectangular frame structure at its top. The upper half of the frame structure passes through the grooves 35 on the two suspensions 31, and the lower half is fixed to a section of the drive chain 52 located below the suspension 31.

[0083] In this embodiment, drive wheels 54 are fixed on the two output shafts of the power motor 53, so that the drive chain 52 rotates on the guide wheel 51, thereby driving the basket 32 ​​to slide under the suspension 31.

[0084] In another specific embodiment:

[0085] See Figures 1-6 The device also includes pressing assemblies 60 disposed on both sides of the end of the basket 32 ​​away from the suspension 31. The pressing assembly 60 includes a support plate 61, a slide rod 62, a limiting plate 63, and a spring 64. A drilling device for drilling is mounted on the basket 32, and this drilling device is similar to the drilling mechanism on a conventional drilling machine, capable of driving the drill bit 33 downwards and allowing for the replacement of the drill bit 33.

[0086] The support plate 61 is installed on the drilling equipment and can descend together with the drill bit 33. The surface of the support plate 61 is on a horizontal plane. The support plate 61 has a sliding hole in the middle. The extension direction of the support plate 61 is consistent with the extension direction of the two support rods 21.

[0087] The slide rod 62 passes through the sliding hole, and its length is perpendicular to the surface of the support plate 61. A limiting plate 63 is fixedly installed at each end of the slide rod 62, and the area of ​​the limiting plate 63 is larger than the area of ​​the sliding hole. A gap exists between the limiting plate 63 located below the support plate 61 and the top surface of the support rod 21 to facilitate the placement of sheet metal.

[0088] Spring 64 is sleeved on slide rod 62. Spring 64 is located below support plate 61, and both ends of spring 64 are fixedly set on the top surface of limit plate 63 and the lower side surface of support plate 61, respectively.

[0089] In this embodiment, during the drilling process, the drilling equipment drives the drill bit 33 to move downwards and causes the support plate 61 to move downwards, thereby causing the limiting plate 63 at the bottom of the slide rod 62 to move downwards and press down the sheet metal on the support rod 21, preventing the rotation of the drill bit 33 from causing displacement of the sheet metal.

[0090] In another specific embodiment:

[0091] See Figures 1-5 The device also includes a handle 71 that drives the two support rods 21 to move in different directions, a drive block 72, a guide plate 73, a bevel gear set, and a sliding screw 74.

[0092] Each of the two support rods 21 has two through holes at one end of the same lower rail 22, and a threaded hole is provided between the two through holes. The through holes and the threaded hole on the two support rods 21 are aligned with each other.

[0093] The drive block 72 is located between the two support rods 21 and on one side of the lower track 22. A guide plate 73 is fixed at each end of the drive block 72, and the two ends of the two guide plates 73 pass through the through holes located on the two support rods 21.

[0094] The drive block 72 has a hollow structure in the middle, and the aforementioned bevel gear set is located inside the drive block 72. The bevel gear set consists of three meshing bevel gears, with two bevel gears arranged opposite each other and fixedly connected to one end of a sliding screw 74. The other ends of the two sliding screws 74 extend in a direction away from each other, and the other ends of the two sliding screws 74 pass through threaded holes on the two support rods 21 and engage with them. The other bevel gear in the bevel gear set is located on a handle 71. The handle 71 is Z-shaped, and one end of the handle 71 passes through one end of the drive block 72 and connects to the bevel gear.

[0095] In this embodiment, by rotating the bevel gear set with handle 71, the two sliding screws 74 rotate in opposite directions, causing the two support rods 21 to move in opposite directions at the same speed. By adjusting the distance between the two support rods 21, the risk of the drill bit 33 colliding with the support rods 21 when drilling large holes is avoided.

[0096] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
