Description

Technical Field

[0001] This utility model relates to the field of CNC machining equipment technology, and in particular to a CNC machining equipment with clamping function. Background Technology

[0002] CNC machining equipment mainly includes CNC lathes, CNC milling machines, stamping machines, etc. Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube and profile, causing plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the required shape and size.

[0003] When stamping workpieces, most processing equipment is equipped with clamping components to hold and fix the workpieces to be stamped, ensuring the stability of the stamping process. However, for some workpieces that need to be punched with holes, and multiple holes need to be punched, the workpieces need to be removed from the clamping components, adjusted in position, and then clamped again. This process needs to be repeated many times to complete the punching operation, which is quite troublesome. Utility Model Content

[0004] The purpose of this utility model is to provide a CNC machining equipment with clamping function in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A CNC machining equipment with clamping function includes a machine body and a stamping device disposed on the upper end of the machine body. A controller is disposed on one side of the machine body, and a worktable is disposed on the upper end of the machine body. A buffer clamping assembly is disposed on the upper end of the worktable. The worktable includes a fixed plate fixedly disposed on the upper end of the machine body and a sliding plate slidably disposed on the upper end of the fixed plate. The sliding plate and the fixed plate are slidably connected by a connecting assembly.

[0007] The buffer clamping assembly includes two clamping plates and a movable plate symmetrically slidably disposed on the upper surface of the sliding plate. Electric push rods for driving the movable plate to move are respectively provided on both sides of the upper surface of the sliding plate. The two movable plates are respectively connected to the clamping plates on opposite sides by connecting springs.

[0008] As a further description of the above technical solution:

[0009] The connecting assembly includes a first slider slidably disposed on the lower end face of the sliding plate and a second slider slidably disposed on the upper end face of the fixed plate. The first slider and the second slider are fixedly connected and both are T-shaped. The lower end face of the sliding plate and the upper end face of the fixed plate are respectively provided with a first groove for sliding of the first slider and the second slider. A limiting member is provided in the middle of the first slider and the second slider.

[0010] As a further description of the above technical solution:

[0011] The limiting component includes a first groove on the upper end face of the first slider and a second groove on the lower end face of the second slider. A pressure block is slidably disposed in the first groove, and a pressing plate is slidably disposed in the second groove. The pressing plate is connected to the bottom surface of the first groove by a compression spring. A sliding rod is fixedly disposed at the lower end of the pressure block, and the lower end of the sliding rod movably penetrates into the second groove and is fixedly connected to the upper end face of the pressing plate.

[0012] As a further description of the above technical solution:

[0013] The sliding plate has a first groove for pressing a pressure plate to compress the pressure block. The lower end of the moving plate has an installation groove, and a rotating rod for pressing the pressure plate is rotatably installed in the installation groove.

[0019] The upper end face of the first slider and the lower end face of the extrusion plate are serrated.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] In this invention, by setting a fixed plate, a sliding plate, a clamping plate, a moving plate, a connecting spring, a rotating rod, a pressure plate, and a connecting assembly, after the two clamping plates clamp the workpiece, the sliding plate can slide to adjust the position of the clamped workpiece. When the electric push rod further drives the moving plate to move, it will cause the rotating rod to be deflected by pressure, thereby squeezing the pressure plate downward.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-4 As shown, a CNC machining equipment with clamping function includes a body 1 and a stamping device 2 located on the upper end of the body 1. A controller 3 is provided on one side of the body 1, and a worktable is provided on the upper end of the body 1. A buffer clamping assembly is provided on the upper end of the worktable. The worktable includes a fixed plate 4 fixedly located on the upper end of the body 1 and a sliding plate 5 slidably located on the upper end of the fixed plate 4. The sliding plate 5 and the fixed plate 4 are slidably connected by a connecting assembly.

[0029] The buffer clamping assembly includes two clamping plates 8 and a movable plate 9 symmetrically slidably disposed on the upper end face of the sliding plate 5. Electric push rods 7 for driving the movable plate 9 to move are respectively provided on both sides of the upper end of the sliding plate 5. The two movable plates 9 are respectively connected to the clamping plates 8 through connecting springs 10 on opposite sides. The electric push rods 7 drive the two movable plates 9 to move relative to each other, so that the two clamping plates 8 move relative to each other, thereby achieving the effect of clamping the workpiece.

[0030] Furthermore, the connecting assembly includes a first slider 15 slidably disposed on the lower end face of the sliding plate 5 and a second slider 16 slidably disposed on the upper end face of the fixed plate 4. The first slider 15 and the second slider 16 are fixedly connected and both are T-shaped. The lower end face of the sliding plate 5 and the upper end face of the fixed plate 4 are respectively provided with a first groove 6 for sliding of the first slider 15 and the second slider 16. A limiting member is provided in the middle of the first slider 15 and the second slider 16. The sliding plate 5 can move laterally and longitudinally on the upper end face of the fixed plate 4, thereby driving the clamped workpiece to adjust its position.

[0031] Furthermore, the limiting component includes a first groove on the upper end face of the first slider 15 and a second groove on the lower end face of the second slider 16. A pressure block 17 is slidably provided in the first groove, and a pressing plate 20 is slidably provided in the second groove. The pressing plate 20 is connected to the bottom surface of the first groove through a compression spring 18. A sliding rod 19 is fixedly provided at the lower end of the pressure block 17. The lower end of the sliding rod 19 moves through the second groove and is fixedly connected to the upper end face of the pressing plate 20.

[0032] Furthermore, the first groove 6 of the sliding plate 5 is provided with a pressure plate 14 for pressing the pressure block 17. The lower end of the moving plate 9 is provided with an installation groove, in which a rotating rod 13 for pressing the pressure plate 14 is rotatably provided. The upper surface of the sliding plate 5 is provided with a second groove 12 that cooperates with the rotating rod 13. When the clamping plate 8 holds the workpiece, the electric push rod 7 further drives the moving plate 9 to move, which will cause the rotating rod 13 to be squeezed and rotated, thereby squeezing the pressure plate 14 to move downward. The pressure plate 14 squeezes the pressure block 17, causing the pressure block 17 and the pressing plate 20 to move downward. Therefore, the sliding limit effect of the first slider 15 and the second slider 16 is achieved, that is, the stability of the sliding plate 5 on the fixed plate 4 is ensured. When the position of the workpiece needs to be adjusted, the operator only needs to retract the electric push rod 7, so that the pressure block 17 and the pressing plate 20 move upward under the reset action of the compression spring 18, releasing the limiting constraint on the first slider 15 and the second slider 16. Then the operator can adjust the position of the workpiece without removing the workpiece from the clamping assembly.

[0033] Furthermore, guide rods 11 are fixedly provided on opposite sides of the two clamping plates 8, and guide holes that cooperate with guide rods 11 are provided on the movable plate 9.

[0034] Furthermore, the upper end face of the pressure block 17 is rotatably fitted with ball bearings 21 that cooperate with the lower end face of the pressure plate 14.

[0035] Furthermore, the upper end face of the first slider 15 and the lower end face of the extrusion plate 20 are serrated, which effectively ensures the friction of the contact surfaces of the upper end face of the first slider 15 and the lower end face of the extrusion plate 20.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
