Description

Technical Field

[0001] This utility model relates to the field of container processing technology, specifically to a clamping device for processing container steel plates. Background Technology

[0002] Drilling equipment refers to a collective term for machinery and equipment that uses tools harder and sharper than the target object to leave cylindrical holes or openings in the target object through rotary cutting or rotary extrusion. It plays a vital role in industrial production. Containers are used to transport packaged or unpackaged goods and are easily loaded and unloaded by mechanical equipment. Drilling equipment is required to drill holes in the steel plates of containers during their manufacturing process.

[0003] A search revealed Chinese patent application number CN202223120687.1, which discloses a drilling device for processing container steel plates, including a drilling unit and a chip collection unit. The drilling unit includes a drilling assembly, a clamping worktable assembly, and a lifting assembly. The container steel plate is placed on the clamping worktable assembly and clamped by the clamping worktable. The lifting assembly drives the drilling assembly to move relative to the clamping worktable assembly. The chip collection unit includes a wind box and a fan duct assembly. The fan duct assembly sucks the drilling chips into the wind box.

[0004] In the process of implementing this utility model, the inventors discovered the following problems with the existing technology:

[0005] The existing clamping table can only clamp and fix both ends of the same type of workpiece, leaving the bottom of the workpiece unsupported and suspended. This causes the workpiece to deform at the stress point during drilling due to the lack of support, thus reducing the quality of the workpiece.

[0006] Therefore, this utility model urgently needs to solve the problem of providing a clamping device for processing container steel plates that can clamp and fix workpieces of different sizes during use, and can support the workpieces by means of a support plate composed of multiple liftable support units. On the one hand, it prevents the workpieces from being suspended in the air, thus avoiding deformation of the workpiece at the drilling point during the drilling process and affecting the quality of the workpiece. On the other hand, it drives one or two corresponding support units on the lifting support plate to move downward according to the processing position to form a clearance groove, so as to prevent damage to the support plate during processing and extend its service life. Utility Model Content

[0007] To address the aforementioned technical problems, the purpose of this utility model is to overcome the limitation that existing clamping worktables can only clamp and fix both ends of workpieces of the same type, leaving the bottom of the workpiece unsupported and suspended. This causes deformation at the stress point during drilling, reducing workpiece quality. The present invention provides a clamping device for container steel plate processing that can clamp and fix workpieces of different sizes. The device uses a support plate composed of multiple liftable support units to support the workpiece, preventing it from being suspended and thus avoiding deformation at the drilling point during drilling, which would affect workpiece quality. Furthermore, the device moves one or two corresponding support units on the lifting support plate downwards according to the processing position to form a clearance groove, preventing damage to the support plate during processing and extending its service life.

[0008] To achieve the above objectives, this utility model provides a clamping device for processing container steel plates, the device comprising: a workbench, a support plate, a clamping plate, and a pressure plate;

[0009] The upper part of the workbench is recessed inward to form an assembly groove.

The support plate is spliced ​​together from several support units that can be raised and lowered. Vertical plates are respectively fixedly installed on the workbench on both sides of the support plate. Clamping plates are vertically and movably installed between the two plates, which can move close to each other on the support plate to clamp and fix the workpiece. Pressure plates that can abut against the workpiece are horizontally and raised and lowered on the facing surfaces of the two clamping plates.

[0010] Preferably, the lower part of the workbench is recessed inward to form an operating groove, and at least two screws are provided at the bottom of each support unit in a vertically rotatable manner with a gap between them. Two threaded holes are provided at a gap between them and vertically through the mounting groove of each support unit to cooperate with the two screws on each support unit. The bottom end of each screw passes through the corresponding threaded hole and extends into the operating groove.

[0011] Preferably, the bottom ends of the two screws on each support unit are respectively coaxially fixed with sprockets, and the two sprockets are connected together by chain drive, and the bottom end of any one of the screws is coaxially fixed with a knob.

[0028] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0029] like Figure 1-6 As shown, the present invention provides a clamping device for processing container steel plates, the device comprising: a workbench 1, a support plate, a clamping plate 5, and a pressure plate 6;

[0030] The upper part of the workbench 1 is recessed inward to form an assembly groove 2. The opening of the assembly groove 2 is horizontally provided with a support plate that is flush with the upper surface of the workbench 1 and is used to support the workpiece. The support plate is spliced ​​together from several support units 3 that can be raised and lowered. Vertical plates 4 are respectively fixedly installed on the workbench 1 on both sides of the support plate. Clamping plates 5 are vertically and movably installed between the two plates, which can move close to each other on the support plate to clamp and fix the workpiece. Pressure plates 6 that can abut against the workpiece are respectively horizontally and raised and lowered on the facing surfaces of the two clamping plates 5.

[0031] In the above scheme, such as Figure 2 As shown, the workpiece to be processed is placed horizontally on the support plate on the worktable 1, and the two clamping plates 5 are driven to move towards the workpiece until the two clamping plates 5 abut against the workpiece. The two pressure plates 6 on the two clamping plates 5 are then driven to descend vertically until the two pressure plates 6 abut against the workpiece, thus completing the clamping and fixing operation of the workpiece, thereby firmly clamping and fixing the workpiece on the worktable 1. The worktable 1 is moved to a prior art drilling device, for example, patent application number CN202223120687.1 cited in the background art, which discloses a drilling unit (wherein, the drilling unit includes: a drilling assembly and a lifting assembly, the lifting assembly driving the drilling assembly to move relative to the clamping worktable assembly, the drilling assembly further including a frame assembly, the frame assembly including a base, two support plates, two slide rails and a top plate, the two support plates being vertically arranged at both ends of the base, the top plate being connected to the top of the two support plates, and the two slide rails being... The drilling assembly is vertically mounted on the support plate. Both ends of the drilling assembly move along the two slide rails. The connecting pipe passes through the top plate. The lifting assembly includes two electric push rods. The fixed ends of the two electric push rods are spaced apart on the lower side of the top plate. The output ends of the two electric push rods are connected to both sides of the drilling assembly. Alternatively, the workpiece can be drilled using a handheld electric drill. The workpiece can be firmly fixed on the support plate on the worktable 1 by two clamping plates 5 and two pressure plates 6 to prevent the workpiece from shifting during processing and affecting the quality of the workpiece.

[0032] like Figure 4 As shown in the figure, the arrow indicates the drilling position. When drilling the fixed workpiece at the position indicated by the arrow, before drilling, the support unit 3 directly opposite the arrow position is moved downward in the vertical direction so that the lowered support unit 3 forms a clearance groove with the side walls of the two adjacent support units 3. During the drilling process, the drill bit will pass through the workpiece and extend into the formed clearance groove, thus avoiding the drill bit from touching the support unit 3. The remaining support units 3 can support the area outside the workpiece drilling area, preventing the workpiece from being suspended in the air and avoiding deformation of the workpiece at the drilling point during the drilling process, which would affect the quality of the workpiece.

[0033] like Figure 5As shown in the figure, the arrows indicate the drilling positions. When the drilling position of the workpiece is at the junction of two support units 3, the two support units 3 can be moved downwards in the vertical direction to form a clearance groove between the two descending support units 3 and the two adjacent support units 3. During the drilling process, this prevents the drill bit from touching the two support units 3. The remaining support units 3 can support the area outside the workpiece drilling, preventing the workpiece from being suspended and avoiding deformation of the workpiece at the drilling point during the drilling process, which would affect the quality of the workpiece.

[0034] Furthermore, since the two clamping plates 5 can approach each other on the support plate, and the two pressure plates 6 on them can move up and down vertically, the distance between the two clamping plates 5 can be changed or adjusted to control the spacing between them, making it suitable for clamping workpieces of different widths or lengths on the support plate. Similarly, by changing or adjusting the descent height of the two pressure plates 6, workpieces of different thicknesses can be clamped and fixed on the support plate. Therefore, through the combined use of the two pressure plates 6 and the two clamping plates 5, workpieces of different sizes can be clamped and fixed on the worktable 1.

[0035] In summary, this utility model can clamp and fix workpieces of different sizes through clamping plates, pressure plates, and support plates. During processing, the support plate, which is composed of multiple liftable support units 3, can support the workpiece. On the one hand, it prevents the workpiece from being suspended in the air, thus avoiding deformation at the drilling point and affecting the quality of the workpiece. On the other hand, according to the processing position, one or two corresponding support units 3 on the lifting support plate can be driven to move downward to form a clearance groove, thereby preventing damage to the support plate during processing and extending its service life.

[0036] In a preferred embodiment of this utility model, the lower end of the workbench 1 is recessed inward to form an operating groove, and at least two screws 11 are provided at the bottom of each support unit 3 at intervals and vertically rotatably. Two threaded holes are respectively opened at intervals and vertically through the mounting groove 2 of each support unit 3 to cooperate with the two screws 11 on each support unit 3. The bottom end of each screw 11 passes through the corresponding threaded hole and extends into the operating groove.

[0037] In the above scheme, since the two screws 11 on each support unit 3 are rotatably connected to the support unit 3, the support unit 3 will not rotate during the synchronous rotation of the two screws 11.

[0038] In use, the two screws 11 on each support unit 3 and the two threaded holes on the corresponding mounting groove 2 work together to drive the support unit 3 to move up and down in the vertical direction during the synchronous rotation of the two screws 11.

[0039] In a preferred embodiment of this utility model, the bottom ends of the two screws 11 on each support unit 3 are respectively coaxially fixed with sprockets, and the two sprockets are connected together by a chain 12. A knob is coaxially fixed at the bottom end of any one of the screws 11.

[0040] In the above scheme, since the two screws 11 on each support unit 3 are connected together by the chain 12, the other screw 11 can be rotated synchronously by the knob on the screw 11. This makes the two screws 11 on each support unit 3 rotate synchronously. During the synchronous rotation of the screws 11, the two threaded holes on the corresponding mounting grooves 2 can drive the support unit 3 to descend, so that the descended support unit 3 is lower than the two adjacent support units 3. This allows the descended support unit 3 to form a clearance groove with the side walls of the two adjacent support units 3. During the drilling of the part of the workpiece located on the support unit 3, the drill bit will pass through the workpiece and extend into the formed clearance groove, thus avoiding the drill bit touching the support unit 3.

[0041] In a preferred embodiment of this utility model, the device further includes: a first electric telescopic rod 7, used to drive the two clamping plates 5 to move closer together; wherein,

[0042] Each of the upright plates 4 is horizontally fixed with a first electric telescopic rod 7, and the telescopic ends of the two first electric telescopic rods 7 are respectively fixed on the two clamping plates 5.

[0043] In the above scheme, by driving the telescopic end of the first electric telescopic rod 7 to extend from or retract into its cylinder, the two clamping plates 5 can be driven to move closer to each other to clamp the workpiece or move away from each other to release the clamping operation on the workpiece, so as to remove the processed workpiece.

[0044] In a preferred embodiment of this utility model, at least two guide rods 9 are fixedly and horizontally at intervals on each clamping plate 5 facing away from the pressure plate 6, and each upright plate 4 is provided with guide holes at intervals and horizontally through which the two guide rods 9 on each clamping plate 5 connected thereto pass, and the free end of each guide rod 9 passes through the corresponding guide hole.

[0045] In the above scheme, through the cooperation of the guide rod and the guide hole, the telescopic end of the first electric telescopic rod 7 can extend from its cylinder or retract into its cylinder, thereby driving the two clamping plates 5 to move closer to each other to clamp the workpiece or move away from each other to release the clamping operation of the workpiece, so as to remove the processed workpiece.

[0046] In a preferred embodiment of this utility model, the device further includes: a second electric telescopic rod 8, used to drive each of the pressure plates 6 to rise and fall vertically; wherein,

[0047] Each clamping plate 5 has a hollow interior and a lifting plate 13 is horizontally and vertically mounted inside it. A second electric telescopic rod 8 is vertically fixed at the upper end of each clamping plate 5. The telescopic end of the second electric telescopic rod 8 extends from the top of the clamping plate 5 into its interior and is fixed to the lifting plate 13. At least two n-shaped connecting rods 10 are vertically fixed at the upper end of each pressure plate 6 at intervals. The other end of each connecting rod 10 extends from the top of the corresponding clamping plate 5 into its interior and is fixed to the lifting plate 13.

[0048] In the above scheme, during use, by driving the extension end of the second electric telescopic rod 8 to extend from or retract into its cylinder, the lifting plate 13 can be driven to rise and fall smoothly and reliably in the vertical direction within the clamping plate 5. During the rising and falling process, the lifting plate 13 drives the pressure plate 6 to rise and fall together in the vertical direction through the connecting rod 10, so that the pressure plate 6 can either descend and abut against the workpiece to fix it, or rise and leave the workpiece to release the fixing operation.

[0049] Furthermore, both the first electric telescopic rod 7 and the second electric telescopic rod 8 are servo electric cylinders, and their models can be appropriately selected according to actual usage. Servo electric cylinders are modular products that integrate a servo motor and a lead screw, with a speed of 0.1–2 m / s. Due to closed-loop servo control, they offer high control accuracy. They are characterized by low cost and flexible configuration, making them the best alternative to hydraulic and pneumatic cylinders.

[0050] In summary, the clamping device for processing container steel plates provided by this utility model overcomes the problem that the existing clamping worktable can only clamp and fix both ends of the same type of workpiece, leaving the bottom of the workpiece unsupported and suspended. This causes the workpiece to deform at the stress point during drilling due to the lack of support, thereby reducing the quality of the workpiece.

[0051] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0052] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0053] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
