Detailed Implementation

[0014] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0015] Please see Figures 1 to 4The present invention provides a processing fixture for a notch on the edge of a workpiece, comprising a base 1 and a pressure plate 2. The base 1 is provided with several sets of slots, which are arranged sequentially along the length of the base 1. The spacing between adjacent sets of slots is set. Each set of slots includes a first groove 101, several second grooves 102 and several blanking holes 103. Several second grooves 102 are arranged sequentially along the length direction of the slot, and the first groove 101 connects two adjacent second grooves 102. The first groove 101 is located in the middle of the second groove 102. The material discharge hole 103 penetrates the base 1 along the thickness direction of the base 1, and one material discharge hole 103 is provided between two adjacent second grooves 102; The pressure plate 2 is provided with a plurality of through holes 201 and a plurality of clamping members 202. The through holes 201 penetrate the pressure plate 2 along the thickness direction of the pressure plate 2. The clamping members 202 are provided on the pressure plate 2 and are positioned towards the base 1. One through hole 201 is located directly above a material discharge hole 103, and one clamping member 202 is located directly above a second groove 102.

[0016] Specifically, in this embodiment, several locking positions are machined along the length of the base 1, and each locking position fixes several external blanks 301. The locking position structure is as follows: each locking position includes several second grooves 102, two adjacent second grooves 102 are connected through a first groove 101, and a material drop hole 103 is provided between two adjacent second grooves 102. The first groove 101 is located in the middle of the length of the second groove 102. One second groove 102 is used to accommodate one external blank 301. This structure pre-fixes the external blanks 301 to prevent the external blanks 301 from deflecting or shifting. The material drop hole 103 penetrates the base 1 along the thickness direction of the base 1. Several through holes 201 are machined in the pressure plate 2. The number of blanks 301 is the same as the number of blanking holes 103, and the number of clamping fasteners 202 is the same as the number of second grooves 102. After several external blanks 301 are fixed in several second grooves 102 of the base 1, the pressure plate 2 is pressed on the base 1. First, one clamping fastener 202 on the pressure plate 2 abuts against the surface of one external blank 301. The setting of the clamping fastener 202 fixes the external blank 301 again, so that the process of locking the pressure plate 2 and the base 1 ensures that the blank 301 is in a stationary state, thereby ensuring the stability of the processing quality of the blank 301. The external punch cutter passes through the through hole 201 and punches the edges of two adjacent blanks 301 at the same time. The scrap after punching is discharged through the blanking hole 103, thus completing the purpose of blank production.

[0017] By setting a first groove 101, several second grooves 102, and several blanking holes 103 on the base 1, the first groove 101 connects two adjacent second grooves 102. The pressure plate 2 is provided with several through holes 201 and several clamping fasteners 202. One second groove 102 pre-fixes one external blank 301, and one clamping fastener 202 fixes one external blank 301 for a second time. This ensures that the blank 301 is in a stationary state during the locking process between the pressure plate 2 and the base 1, thereby ensuring the stability of the processing quality of the blank 301. The external punch cutter passes through the through holes 201 to punch and cut the edges of two adjacent blanks 301. The waste is discharged through the blanking holes 103, achieving the purpose of mass production and improving the stability of processing quality.

[0018] The first groove 101 extends through the base 1 along the width direction of the base 1, which facilitates the processing of the base 1.

[0019] The width of the discharge hole 103 is smaller than the distance between two adjacent second grooves 102. The waste material on the edge of the external blank 301 that has been cut off is discharged through the discharge hole 103, and the waste material is removed in time.

[0020] Each of the clamping components 202 includes a connecting piece 2a and a suction cup 2b disposed on the connecting piece 2a. The pressure plate 2 is provided with a plurality of receiving grooves 203, and one connecting piece 2a is disposed in one of the receiving grooves 203. The suction cup 2b is disposed facing the base 1 and adopts a rubber ring structure. When the pressure plate 2 presses the surface of the external blank 301 fixed by the base 1, the suction cup 2b first contacts the blank 301. Under the action of the plurality of suction cups 2b, the blank 301 is fixed again, thereby completely avoiding the deflection phenomenon of the blank 301 during the locking process of the pressure plate 2 and the base 1, and further improving the controllability of processing quality.

[0021] Each of the clamping components 202 also includes a buffer component 2c, which is connected to the connecting piece 2a. The suction cup 2b and the buffer component 2c are located on opposite sides of the connecting piece 2a. The buffer component 2c is provided to prevent external pressure from being applied instantaneously to the surface of the external blank 301 and causing impact force on the blank 301, thus protecting the external blank 301.

[0022] The buffer 2c is a rubber component, which utilizes the elasticity of the rubber component to achieve a buffering effect.

[0023] The buffer 2c is provided with a plurality of protrusions, which are located on the side surface of the buffer 2c. The protrusions abut against the inner wall of the receiving groove 203, increasing the frictional resistance between the buffer 2c and the receiving groove 203, so that the buffer 2c has hysteresis during the compression process.

[0024] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
