Description

Technical Field

[0001] The utility model belongs to the technical field of metal plate processing, and more specifically, particularly relates to a plate processing clamping device. Background Art

[0002] Sheet metal processing refers to the process of turning sheet metal into products or parts of the required shape and size through a series of processing techniques. Sheet metal processing is an important part of the manufacturing industry and is widely used in the fields of automobiles, aviation, home appliances, construction, etc. Existing sheet metal processing equipment usually consists of a machine tool work surface, a clamping device, and a processing tool.

[0003] The utility model with the existing application number 2022212339401 discloses a hydraulic clamping device for machine tool plate processing, including a machine tool, a hydraulic assembly is arranged outside the machine tool, one end of the hydraulic assembly is fixedly connected with a clamping plate, a first slide groove is provided inside the clamping plate, a buffer cover is slidably connected to the outside of the slide groove, and a spring is fixedly connected to the outside of the clamping plate. The advantages of the utility model are: the device is convenient for playing a buffering and protective role when clamping the plate by arranging the buffer cover and the spring, and has a buffering effect between the clamping plate and the plate, protecting both sides of the plate, avoiding hard contact between the clamping plate and the plate, preventing damage to the plate, ensuring the quality of the plate, and reducing economic losses; by arranging the rotating rod and the shovel block, it is convenient to place the plate on the machine tool instead of placing it by hand, thereby avoiding squeezing the worker's fingers and reducing the danger, and at the same time, it is convenient to take out the processed plate and convenient for the worker to carry the plate.

[0004] Based on the above, although the shovel block can lift the plate placed on the machine tool, the shovel block cannot remain in the raised state for a long time. Therefore, the worker needs to step on the block with his feet while using both hands to move the plate. Not only is the operation inconvenient, but the workers are also prone to lose balance and fall due to the heavy plates, resulting in injuries. Utility Model Content

[0059] The lifting components include:

[0060] A first rack 601, which is fixedly connected to the back of the drawer 6;

[0061] A first rotating shaft 7, the first rotating shaft 7 is rotatably connected to the inner sides of the two fixing plates 5;

[0062] The first gear 701 is coaxially fixedly connected to the outside of the first rotating shaft 7, and the first gear 701 is meshed with the first rack 601. The effect brought about is that when the drawer 6 is pulled forward, the first gear 701 and the first rotating shaft 7 can be driven to rotate through the gear-rack transmission mechanism jointly formed by the meshing of the first gear 701 and the first rack 601.

[0063] Among them, the lifting components also include:

[0064] A second rack 8, which is slidably connected to the bottom of the workbench 101 and meshes with the first gear 701;

[0065] The connecting member 801 is fixedly connected behind the second rack 8, so that the first gear 701 drives the connecting member 801 to move backward through the gear-rack transmission mechanism formed by meshing with the second rack 8.

[0066] Among them, the lifting components also include:

[0067] Sliding block 9, two sliding blocks 9 are provided, and the two sliding blocks 9 are slidably connected inside the two fixing plates 5 respectively;

[0068] A first connecting rod 901, wherein two first connecting rods 901 are provided, and the two first connecting rods 901 are separately fixedly connected to the inner sides of the two sliding blocks 9;

The effect brought about is that the connecting member 801 will drive the first connecting rod 901, the second connecting rod 10 and the supporting block 4 to move backward at the same time through the second rotating shaft 11.

[0071] Among them, the lifting components also include:

[0072] A guide rail 12, the guide rail 12 is fixedly connected under the workbench 101;

[0073] The roller 13 is rotatably connected to the bottom of the support block 4 , so that when the support block 4 moves to the point where the roller 13 contacts the guide rail 12 , the second connecting rod 10 climbs upward to lift the support block 4 .
