Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a clamping device for numerically controlled lathes. Background Art

[0002] A CNC machine tool, short for digitally controlled machine tool, is an automated machine tool equipped with a program control system. This control system logically processes programs specified by control codes or other symbolic instructions, decodes them, and represents them as coded numbers, which are then input into the CNC device via an information carrier. After computational processing, the CNC device issues various control signals, controlling the machine's movements and automatically producing parts to the shape and size specified in the drawings.

[0003] The existing Chinese patent with announcement number CN215546929U discloses a clamping device for a CNC lathe. The above-mentioned existing technical solution has the following defects. Although the above-mentioned technical solution is convenient for quantitative spraying of cutting fluid, reduces the waste of cutting fluid, and improves the efficiency of cutting fluid use, in the above-mentioned technical solution, when clamping and fixing the parts, a second spring and a clamping plate are used to clamp the parts. Due to the elasticity of the spring, potential energy is generated when the parts are processed, which will cause the second spring to deform, so the clamping plate will be tilted and offset, which can easily reduce the clamping and fixing effect of the parts.

[0004] To this end, we proposed a clamping device for CNC lathes to solve the above-mentioned drawbacks. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a clamping device for a CNC lathe.

[0006] The transmission mechanism is constituted by a toothed plate and a toothed plate, and the toothed plate is fixed with a toothed plate so as to prevent the toothed plate from sliding out of the gear train.

[0007] Preferably, the top surface of the support box is provided with a frame on the outside of the workbench, and a connecting groove is opened around the inner wall of the frame. Connecting blocks are provided on both side surfaces of the workbench, and one end of the connecting block extends to the inside of the connecting groove.

[0008] Preferably, the connecting block is movably connected to the connecting groove.

[0009] Preferably, there are a plurality of fixed boxes, and the plurality of fixed boxes are evenly distributed around the top surface of the workbench.

[0010] Preferably, the limiting block is movably connected to the limiting rod.

[0011] Preferably, there are a plurality of anti-slip teeth, and the plurality of anti-slip teeth are evenly distributed on one side surface of the clamping plate.

[0012] Preferably, a partition is provided inside the supporting box, and a storage box is provided below the partition. A handle is provided on the front end surface of the storage box, and the storage box is movably connected to the supporting box.

[0013] Preferably, the front end surface of the support box is fixedly connected to a movable plate by screws, and a through opening is penetrated through the front end surface of the movable plate. The front end surface of the support box is located below the movable plate and is hinged with a box door by a hinge.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) In the present invention, the part to be processed is placed on the top surface of the workbench, and the second motor on the side of the lower surface of the top of the fixed box is turned on. The second motor drives the gear to rotate, and the gear drives the rack to move while rotating. The rack moves while driving the clamping plate to move. When the anti-slip teeth on the surface of one side of the clamping plate abut against the part, it can be automatically clamped and fixed to prevent the part from tilting and shifting during processing, thereby facilitating the maintenance of the stability of the part during processing. After clamping and fixing, the part can be processed by a CNC lathe, which is beneficial to improving its processing effect.

[0016] (2) The present invention can clamp parts in multiple directions by using multiple clamping plates to prevent the parts from loosening during processing, thereby facilitating the improvement of the clamping and fixing effect of the parts. The use of anti-slip teeth on the clamping plates can effectively improve the anti-slip effect of the clamping plates, increase the friction between the clamping plates and the parts, and further improve the firmness of the clamping of the parts. The use of connecting blocks and connecting grooves can limit the workbench, facilitate maintaining the stability of the workbench during rotation, and facilitate the processing of parts by CNC lathes.
