Description

Technical Field

[0001] The utility model relates to the technical field of CNC lathes, in particular to a hardware clamping fixture based on CNC lathe processing. Background Art

[0002] Hardware refers to tools made by processing and casting metals such as gold, silver, copper, iron, and tin. Hardware needs to be processed by CNC lathes. CNC lathes are high-performance machine tools that use digital control programs to automatically process workpieces. When hardware is processed on CNC lathes, it needs to be clamped and fixed by fixtures to maintain the stability of the hardware during the processing process.

[0003] The prior art publication number CN213258267U discloses a CNC machine tool processing fixture, which belongs to the field of fixtures. Through the set rotating seat, the clamping mechanism can be rotated as needed, thereby causing the workpiece to rotate to a certain extent, thereby improving the flexibility of the fixture during use. An adjusting rod is used and a connecting structure is used to connect the movable splint. While ensuring normal clamping and increasing the spacing between the splints, the screw can be used to directly move the movable splint. Manual operation is not required by the staff, and the operation is flexible and convenient.

[0004] Although the existing technology has many benefits during use, it still has the following problems: it lacks a structure to raise the workpiece, which results in the clamping plate being unable to adapt to workpieces of different thicknesses. Workers are required to manually place a pad on the lower end of the workpiece to increase the height, affecting the clamping efficiency of the workpiece. Utility Model Content

[0005] The purpose of the utility model is to provide a hardware clamping jig based on CNC lathe processing to solve the problems raised in the above background technology.

[0007] When using a clamping fixture for hardware parts based on numerical control lathe processing in this technical solution, the operator places the workpiece on the upper end of the bottom plate and between the movable clamping plate and the fixed clamping plate. The electric push rod drives the connecting plate and the support plate to move vertically, so that the support plate drives the workpiece to move vertically until the infrared sensor detects the position of the workpiece, achieving the purpose of lifting the workpiece and making the upper end face of the workpiece protrude from the upper end of the fixed clamping plate. The operator manually rotates the screw rod, and the screw rod drives the movable clamping plate to move relatively, and the workpiece is clamped and fixed by the movable clamping plate, the fixed clamping plate and the anti-slip blocks.

[0008] Preferably, fixing blocks are installed on the outer wall of the bottom plate in a rectangular array distribution, and fixing holes are opened inside the fixing blocks. The external bolts fix the bottom plate through the fixing blocks and the fixing holes to ensure the connection between the bottom plate and the machine tool.

[0009] Preferably, anti-slip blocks are installed on the outer walls of the opposite sides of the movable clamping plate and the fixed clamping plate, and anti-slip lines are opened on the outer walls of the anti-slip blocks. The movable clamping plate and the fixed clamping plate improve the friction force with the workpiece through the anti-slip blocks, and the workpiece is clamped and fixed by the movable clamping plate, the fixed clamping plate and the anti-slip blocks.

[0010] Preferably, a support rod is installed on one side of the outer wall of the upper end of the fixed clamping plate, and an infrared sensor is arranged on one side of the outer wall of the support rod. The infrared sensor can detect the position of the workpiece protruding from the fixed clamping plate.

[0011] Preferably, through holes are opened in the bottom plate and the movable clamping plate in an equidistant and parallel distribution, and the through holes are designed in a rectangular shape. The support plate moves inside the through holes.

[0012] Preferably, support plates are installed on the outer wall of the upper end of the connecting plate in an equidistant and parallel distribution. The size of the support plate is smaller than the size of the through hole, and the support plate is located inside the through hole. The support plate can lift the workpiece and adjust the clamping height of the workpiece.

[0013] Preferably, the connecting plate is designed in a rectangular shape and is located at the lower end of the bottom plate. The connecting plate supports the support plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention achieves the effect of adjusting the clamping height of the workpiece by arranging an electric push rod, an infrared sensor and a support plate. The staff places the workpiece on the upper end of the base plate and between the movable clamping plate and the fixed clamping plate. The electric push rod drives the connecting plate and the support plate to move vertically, thereby causing the support plate to drive the workpiece to move vertically until the infrared sensor detects the position of the workpiece, thereby achieving the purpose of lifting the workpiece and making the upper end surface of the workpiece protrude from the upper end of the fixed clamping plate. The staff manually rotates the screw, and the screw drives the movable clamping plate to move relative to the upper end of the fixed clamping plate. The workpiece is clamped and fixed by the movable clamping plate, the fixed clamping plate and the anti-sliding plate, thereby maintaining the position stability of the workpiece and being able to lift the workpiece by itself, avoiding the staff from placing pads, thereby improving the clamping efficiency of the workpiece.
