Description

Technical Field

[0001] The utility model relates to the field of sheet metal drilling, and specifically relates to a fine adjustment mechanism for sheet metal drilling. Background Technique

[0002] Sheet metal is a comprehensive cold processing technology for metal thin plates, including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as automobile body), etc.; its remarkable feature is that the thickness of the same part is consistent; the products processed by sheet metal technology are called sheet metal parts, and when drilling sheet metal parts, it is necessary to adjust the position of the workpiece so that the drilling mechanism can drill different positions of the workpiece. Therefore, a fine adjustment mechanism is required to adjust the position of the workpiece, and the adjustment mechanism generally consists of an electric slide table, a slide seat and a placement plate.

[0003] In the existing fine adjustment mechanism for sheet metal drilling, after the position of the sheet metal part is adjusted, the sheet metal part is drilled by a drilling device. During the drilling process, a large amount of debris is generated, and some debris will fall onto the electric slide table. When the debris accumulates on the electric slide table, the electric slide table can drive the slide seat to move, and then push the debris to move, so that the debris will rub against the top of the electric slide table, thereby increasing the frictional resistance. If the debris gets stuck in the gap between the electric slide table and the slide seat, it may affect the moving efficiency of the slide seat, and at the same time scratch the top surface of the electric slide table, thus causing wear on the top surface of the electric slide table, reducing the service life of the electric slide table, and reducing the protection effect on the electric slide table. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a fine adjustment mechanism for sheet metal drilling to solve the technical problem of poor protection effect on the top surface of the electric slide table.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a fine adjustment mechanism for sheet metal drilling, including a first electric slide table, the output end of the first electric slide table is provided with a first slide seat, and the top of the first slide seat is installed with a second electric slide table, the output end of the second electric slide table is provided with a second slide seat, fixed plates are fixed on both sides of the first electric slide table and on the outer surface and back of the second electric slide table, a second side plate is installed on the fixed plate through a second bolt, first side plates are installed on both sides of the first slide seat and on the outer surface and back of the second slide seat through a first bolt, and a shielding cloth is installed between each first side plate and the second side plate.

[0006] By adopting the above technical scheme, when the first electric slide table works, it can drive the first slide seat to move, and then带动 the second electric slide table to move, and then带动 the placement plate to move.

[0007] Further, the shielding cloth is made of nylon composite fabric, and the shielding cloth is in a "冂" shape.

[0008] By adopting the above technical solution, the covering cloth can be folded or unfolded so that it can continuously cover the top of the first and second electric slides.

[0009] Furthermore, the nylon composite fabric used in the shielding cloth consists of a top layer, a middle layer, and a bottom layer. The top layer is made of polyester industrial yarn, the middle layer is made of nylon mesh fabric, and the nylon mesh fabric is woven from warp and weft. The bottom layer is made of PVC film.

[0010] By adopting the above technical solution, the surface of the polyester industrial yarn has a low coefficient of friction, a smooth surface, and is not easily worn when in contact with metal shavings, and can withstand the scraping of shavings for a long time.

[0011] Furthermore, the shielding cloth is provided in four pieces, with each pair of shielding cloths forming a group, and each group of shielding cloths is located on the outer wall of the first electric slide.

[0012] By adopting the above technical solution, the shielding cloth can shield the top of the first electric slide, thereby preventing the debris generated during the drilling process from falling directly onto the top of the first electric slide.

[0013] Furthermore, another set of the shielding cloth is located on the outer wall of the second electric slide.

[0014] By adopting the above technical solution, the shielding cloth can cover the top of the second electric slide, preventing debris from falling directly onto the top of the second electric slide.

[0015] Furthermore, both the first and second electric slides are enclosed electric slides.

[0016] By adopting the above technical solution, the enclosed electric slide table can prevent debris from falling onto the lead screw inside the electric slide table.

[0017] Furthermore, the shielding cloth and the second side plate are detachably connected to the fixing plate.

[0018] By adopting the above technical solution, the covering cloth can be disassembled and replaced.

[0019] Furthermore, a placement plate is mounted on the top of the second slide.

[0020] By adopting the above technical solution, the placement plate facilitates the placement of sheet metal parts.

[0021] Furthermore, the first and second electric slides are electrically connected to the control panel of the drilling equipment.

[0022] By adopting the above technical solution, the first electric slide or the second electric slide can be started or stopped through the control panel of the drilling equipment.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model is provided with a shielding cloth, a first bolt, a second bolt, a first side plate, and a second side plate. The shielding cloth can cover the top of the first electric slide and the second electric slide, preventing debris from falling directly to the top of the first electric slide and the second electric slide. This prevents hard debris (such as metal shavings) from getting stuck in the gap between the electric slide and the slide block, causing the slide block to jam and affecting the movement of the slide block. This ensures that the slide block can move smoothly. At the same time, it prevents the slide block from pushing the debris to move, causing the debris to rub against the top of the electric slide and scratch the top surface of the electric slide, thereby extending the service life of the electric slide.

[0025] 2. The nylon composite fabric used in the shielding cloth of this utility model consists of a surface layer, a middle layer, and a bottom layer. The surface layer is made of polyester industrial yarn, the middle layer is made of nylon mesh cloth, and the bottom layer is made of PVC film. The surface layer made of polyester industrial yarn has a low coefficient of friction and a smooth surface, making it less prone to wear when in contact with metal shavings and able to withstand the scratches of shavings for a long time. The nylon mesh cloth uses a warp and weft interwoven mesh structure as its skeleton, which can disperse external forces. When the shielding cloth is impacted by shavings or folded and stretched, the mesh structure can evenly transmit stress to the whole, improving tear resistance and making the shielding cloth less prone to deformation after frequent folding and unfolding, maintaining a flat covering state. In addition, the PVC film has the characteristics of being completely waterproof and dustproof, which can prevent fine debris (such as metal powder and plastic particles) from leaking into the electric slide through the shielding cloth.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1:

[0037] A sheet metal part drilling fine-tuning mechanism, such as Figures 1-7 As shown, it includes a first electric slide table, the output end of which is provided with a first slide block, and a second electric slide table is installed on the top of the first slide block. Both the first and second electric slide tables are enclosed electric slide tables. Enclosed electric slide tables can prevent debris from falling onto the lead screw inside the electric slide table. The output end of the second electric slide table is provided with a second slide block. Fixing plates are fixed on both sides of the first electric slide table and on the outer surface and back of the second electric slide table. Second side plates are installed on the fixing plates by second bolts.

[0038] See Figures 1-5 The first slide block has first side plates installed on both sides and the outer surface and back of the second slide block by first bolts. A shielding cloth is installed between each first side plate and the second side plate. The operation of the first electric slide block can drive the first slide block to move, thereby driving the second electric slide block to move, and then driving the placement plate to move. There are four shielding cloths, with two shielding cloths forming a group. One group of shielding cloths is located on the outer wall of the first electric slide block and can shield the top of the first electric slide block, thereby preventing the debris generated during drilling from falling directly to the top of the first electric slide block. The other group of shielding cloths is located on the outer wall of the second electric slide block and can shield the top of the second electric slide block, preventing the debris from falling directly to the top of the second electric slide block.

[0039] Specifically, the shielding cloth and the second side plate are detachably connected to the fixing plate so that the shielding cloth can be removed and replaced. A placement plate is installed on the top of the second slide, which facilitates the placement of sheet metal parts. The first electric slide and the second electric slide are electrically connected to the control panel of the drilling equipment so that the first electric slide or the second electric slide can be started or stopped through the control panel of the drilling equipment.

[0040] Example Two:

[0041] On the basis of the above Example One, in order to enable the shielding cloth 8 to be folded or unfolded, the following materials are used to make the shielding cloth 8.

[0042] Specifically, the shielding cloth 8 is made of nylon composite fabric. The shielding cloth 8 is in the shape of "冂" so that the shielding cloth 8 can be folded or unfolded, enabling the shielding cloth 8 to always shield the tops of the first electric slide table 1 and the second electric slide table 3.

[0043] Example Three:

[0044] On the basis of the above Example Two, in order to improve the scratch resistance of the shielding cloth 8, the following structure is set up.

[0045] Refer to Figures 1-6 , the nylon composite fabric used for the shielding cloth 8 is composed of a surface layer, an intermediate layer and a bottom layer. The surface layer is made of polyester industrial yarn, the intermediate layer is made of nylon mesh cloth, and the nylon mesh cloth is woven by warp and weft. The bottom layer is made of PVC film. The surface layer made of polyester industrial yarn has a low coefficient of friction and a smooth surface, and is not easily worn when contacting metal debris, and can withstand the scratching of debris for a long time.

[0046] The working principle of the present utility model is as follows: First, the staff can first install this mechanism on the drilling device. After installation, the power supply is connected. Then, the placing plate 5 is installed on the second slide seat 4, and the fixture for clamping the sheet metal part is installed on the placing plate 5 (the fixture is not shown in the figure because the fixture is prior art and not the technical problem to be solved in this application, so it is not shown in the figure and not described in detail in the specification). When it is necessary to adjust the position of the sheet metal part, the staff can start the first electric slide table 1 or the second electric slide table 3, so that the placing plate 5 moves, and the sheet metal part placed on the placing plate 5 is moved, thereby adjusting the position of the sheet metal part;

[0047] And because the shielding cloth 8 can shield the tops of the first electric slide table 1 and the second electric slide table 3, preventing debris from directly falling onto the tops of the first electric slide table 1 and the second electric slide table 3, thereby preventing hard debris (such as metal chips) from getting stuck in the gap between the electric slide table and the slide seat, causing the slide seat to be stuck, so as to ensure that the slide seat can move smoothly. At the same time, it prevents the slide seat from pushing the debris to move, causing the debris to rub against the top of the electric slide table and scratch the top of the electric slide table;

[0048] Furthermore, the nylon composite fabric used in the shielding cloth 8 consists of a surface layer, a middle layer, and a bottom layer. The surface layer is made of polyester industrial yarn, the middle layer is made of nylon mesh fabric, and the bottom layer is made of PVC film. The surface layer made of polyester industrial yarn has a low coefficient of friction and a smooth surface, making it less prone to wear when in contact with metal shavings and able to withstand the scratches of shavings for a long time. The nylon mesh fabric uses a woven grid structure as its skeleton, which can disperse external forces. When the shielding cloth 8 is impacted by shavings or folded and stretched, the grid structure can evenly transmit stress to the whole, improving tear resistance and making the shielding cloth 8 less prone to deformation after frequent folding and unfolding, maintaining a flat covering state. In addition, the PVC film has the characteristics of being completely waterproof and dustproof, which can prevent fine debris (such as metal powder and plastic particles) from leaking into the electric slide table through the shielding cloth 8.
