[0034] Please also read Figures 1 to 5, the copper plate punching auxiliary tooling provided by the utility model is now described. The copper plate punching auxiliary tooling includes two brackets 10, two clamping blocks 20, two drag plates and two first driving components. The two brackets 10 are arranged on both sides of the copper plate, and the two brackets 10 are provided with horizontally extending mounting grooves on the sides facing each other; the two clamping blocks 20 are symmetrically arranged on both sides of the copper plate and slide with the brackets 10, and have the freedom to move up and down, and are used to clamp the copper plate; the lower side of the clamping block 20 is provided with an adsorption structure, which is used to adsorb the copper plate; the two support plates 30 are elastically arranged in the two mounting grooves, respectively, and have the freedom to extend or retract into the mounting grooves, and the upper side edge of the support plate 30 facing away from the bracket 10 is chamfered, which is used to retract into the mounting groove under the push of the copper plate or the clamping block 20; the two first driving components are respectively connected to the two brackets 10, and the power output end is connected to the clamping block 20, which is used to drive the clamping block 20 to move up and down.

[0035] The first driving assembly drives the clamping block 20 to move upward, and when the clamping block 20 absorbs the copper plate and moves to the upper side of the support plate 30, the support plate 30 extends out to hold the edges of both sides of the copper plate.

[0036] The beneficial effect of the copper plate punching auxiliary tooling provided by the embodiment of the utility model is as follows: compared with the prior art, the copper plate punching auxiliary tooling provided by the embodiment of the utility model, when punching, the first driving component drives the clamping block 20 to move downward, clamps the copper plate, and performs the punching operation; when the copper plate needs to be moved, the copper plate is adsorbed by the adsorption structure on the clamping block 20, and then the copper plate is driven to move up to the upper side of the support plate 30, and the support plate 30 extends out of the installation slot after being no longer blocked by the clamping block 20 and the copper plate, and drags the copper plate. At this time, the inclined surface formed by the chamfer on the support plate 30 contacts the copper plate, so that the copper plate is separated from the table top of the punching equipment. At this time, pushing and pulling the copper plate can effectively avoid scratching the surface of the copper plate.

[0037] Specifically, when pushing and pulling the copper plate, the adsorption structure can be controlled to stop adsorbing the copper plate to reduce the resistance when moving the copper plate. After the movement is completed, the adsorption structure is controlled to suck the copper plate and lock the position of the copper plate on the horizontal plane. Then, the clamping block 20 is pressed down by the first driving component. The support plate 30 is provided with a chamfer, and the contact surface between the support plate 30 and the copper plate is an inclined surface. Therefore, the support plate 30 is retracted into the installation groove under the top push of the copper plate, and the clamping block 20 continues to move downward to fix the copper plate on the table top of the punching equipment.

[0038] A plurality of springs are installed in the installation grooves, and two ends of the springs are respectively connected to the bracket 10 and the support plate 30 to realize the elastic setting of the support plate 30 .

[0039] like Figure 4 and Figure 5As shown, in a specific implementation of the copper plate punching auxiliary tooling provided in the embodiment of the utility model, the adsorption structure includes a negative pressure chamber 21 provided in the clamping block 20 and a plurality of first adsorption holes provided at the bottom of the clamping block 20 and connected to the negative pressure chamber 21, and the negative pressure chamber 21 is suitable for being connected to a negative pressure source. By connecting the negative pressure chamber 21 to the negative pressure source, the copper plate can be adsorbed through the first adsorption holes.

[0040] Further, such as Figure 4 and Figure 5 As shown, in a specific implementation of the copper plate punching auxiliary tooling provided in an embodiment of the utility model, the adsorption structure also includes a buffer layer 22, the buffer layer 22 is arranged at the bottom of the clamping block 20, and a plurality of second adsorption holes 23 are opened on the buffer layer 22, the second adsorption holes 23 correspond to and are aligned with the first adsorption holes one by one; and the second adsorption holes 23 are conical, with the small end facing upward and the large end facing downward.

[0041] It should be noted that the buffer layer 22 is a wear-resistant rubber layer, which fits tightly with the bottom of the clamping block 20, and can effectively avoid crushing and scratching the copper plate; setting the second adsorption hole 23 into a cone can effectively increase the adsorption area and generate sufficient suction to suck up the copper plate.

[0042] like Figure 1 and Figure 2 As shown, in a specific implementation of the copper plate punching auxiliary tooling provided in an embodiment of the utility model, the upper end surface of the clamping block 20 is an inclined surface inclined downward from one side of the bracket 10, and the first driving assembly includes a driving block 42 and a cylinder 43. The driving block 42 is arranged on the upper side of the clamping block 20 and slides with the clamping block 20, and has the freedom to slide along the upper end surface of the clamping block 20; the cylinder 43 is horizontally arranged and connected to the bracket 10, and the piston rod of the cylinder 43 is connected to the driving block 42, which is used to drive the driving block 42 to move horizontally.

[0043] like Figure 1 and Figure 2 As shown, in a specific implementation of the copper plate punching auxiliary tooling provided in an embodiment of the utility model, the first driving component also includes a fixed block 41, which is arranged on the upper side of the driving block 42, and the lower end face of the fixed block 41 is an inclined surface inclined upward from one side of the bracket 10, and the bisector of the angle between the lower end face of the fixed block 41 and the upper end face of the clamping block 20 is parallel to the axis of the piston rod of the cylinder 43; the driving block 42 is slidably matched with the fixed block 41, and has the freedom to move along the lower end face of the fixed block 41.

[0044] It should be understood that the fixing block 41 is provided to offset the radial force on the piston rod when clamping the copper plate, so that the cylinder 43 is only subjected to axial force during operation, thereby ensuring the service life.

[0045] like Figure 1 and Figure 2As shown, in a specific implementation of the copper plate punching auxiliary tooling provided in an embodiment of the utility model, the upper end surface of the clamping block 20 and the lower end surface of the fixed block 41 are both provided with dovetail grooves, and the upper and lower end surfaces of the driving block 42 are both provided with trapezoidal guide rails that slide in cooperation with the dovetail grooves.

[0046] It should be noted that trapezoidal guide rails may be provided on the upper end surface of the clamping block 20 and the lower end surface of the fixing block 41 , and dovetail grooves may be provided on the upper and lower end surfaces of the driving block 42 .

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
