The air conditioner compressor valve plate is provided with a notch, and different air conditioner compressor valve plates have different notches. The traditional processing method is to first draw a reference line on the valve plate, then use a special clamp to clamp the valve plate, and finally punch the position on the machine tool. Different sizes of valve plates need to be clamped with corresponding clamps, which has high production cost and low production efficiency. SUMMARY

[0003] The present application discloses a punching tool, which solves the problem of high production cost and low production efficiency caused by different clamps for different notches in the prior art.

DETAILED DESCRIPTION

[0021] The present application will be further described below in combination with embodiments, but is not limited to the contents in the description.

[0022] For example, Figure 1 and Figure 2As shown, the present application discloses a punching tool, comprising: a workbench 1; at least two fixing blocks 2, the fixing blocks 2 are movably arranged on the workbench 1, at least one fixing block 2 is located on the first side of the structure to be punched 4, and at least one fixing block 2 is located on the second side of the structure to be punched 4; at least one clamping block 3, the clamping block 3 is rotatably arranged on the fixing block 2, and the clamping block 3 can be rotated to the third side of the structure to be punched 4. The fixing blocks 2 and the clamping blocks 3 are used to clamp and fix the structure to be punched 4 from three directions, so as to ensure the fixing effect. Since the fixing blocks 2 can move, the punching tool can be suitable for structures to be punched 4 of different sizes, overcoming the problem of needing to separately set clamps in the prior art.

[0023] Preferably, the fixing block 2 comprises a first fixing block 21 located on the first side of the structure to be punched 4 and a second fixing block 22 located on the second side of the structure to be punched 4. In use, the structure to be punched 4 is placed on the workbench 1, and the structure to be punched 4 is located between the first fixing block 2 and the second fixing block 2. The first fixing block 2 and / or the second fixing block 2 are moved, so that the first fixing block 2 abuts against the first side surface of the structure to be punched 4 facing the first side, and the second fixing block 2 abuts against the second side surface of the structure to be punched 4 facing the second side. Then the clamping block 3 is turned over, and the clamping block 3 abuts against the third side surface of the structure to be punched 4 facing the third side, that is, the structure to be punched 4 is fixed in three degrees of freedom. Since the punching direction is downward stamping, that is, the direction towards the workbench 1, and the workbench 1 can limit the downward movement of the structure to be punched 4, the fixing is reliable during the stamping process of the structure to be punched 4.

[0024] At least one protrusion 5 is arranged on the side surface of the fixing block 2, and the protrusion 5 can abut against the corresponding side surface of the structure to be punched 4. When the fixing block 2 is worn or damaged, the protrusion 5 can be directly replaced, and the size range of the clamping of the fixing block 2 is increased by arranging multiple protrusions 5, thereby improving the versatility of the punching tool.

[0025] In the direction away from the workbench 1, the length of the protrusion 5 gradually increases. That is, all the protrusions 5 form an inverted step shape. The fixing block 2 can also move away or close along the thickness direction of the workbench 1, so that the required protrusion 5 moves to the set position to clamp and fix the structure to be punched 4. Since the length of the protrusion 5 of the upper layer is greater than that of the protrusion 5 of the lower layer, when the protrusion 5 of the lower layer fixes the structure to be punched 4, the protrusion 5 of the upper layer can limit the structure to be punched 4 from above, further increasing the fixing effect of the structure to be punched 4.

[0026] As shown in the drawings, Figure 1As shown, the fixed block 2 is two, and is respectively arranged on the opposite sides of the to-be-punched structure 4, and each fixed block 2 is provided with a clamping block 3, and the clamping block 3 can move with the movement of the fixed block 2.

[0027] The punching tool further comprises a driving mechanism 6 arranged on the workbench 1, and the driving mechanism 6 can drive the fixed block 2 to approach or move away from the to-be-punched structure 4. The driving mechanism 6 can be a telescopic motor, and the telescopic rod of the telescopic motor is connected to the fixed block 2 and can drive the fixed block 2 to move in a manner parallel to the plane of the workbench 1.

[0028] The punching tool further comprises a rotating block 7 rotatably arranged on the fixed block 2, and the clamping block 3 is connected to the rotating block 7.

[0029] In order to enable the clamping block 3 to fix to-be-punched structures 4 of different sizes, the clamping block 3 can be arranged to move away from or approach the rotating block 7, and the size of the to-be-punched structure 4 matched by the clamping block 3 can be increased by adjusting the distance between the clamping block 3 and the rotating block 7.

[0030] Specifically, the punching tool further comprises a driving rod 8 rotatably arranged on the rotating block 7, and the clamping block 3 is movably arranged on the driving rod 8 to adjust the distance between the clamping block 3 and the rotating block 7. The rotation of the driving rod 8 can drive the clamping block 3 to move along the axis direction of the driving rod 8.

[0031] Optionally, the punching tool further comprises a guide rail 9 arranged on the rotating block 7, and the clamping block 3 is movably arranged on the guide rail 9 to adjust the distance between the clamping block 3 and the rotating block 7. The guide rail 9 limits the movement direction of the clamping block 3, and ensures the reliability of the clamping block 3 after movement.

[0032] The workbench 1 is provided with a groove 10, the to-be-punched structure 4 is placed in the groove 10, and the to-be-punched structure 4 has a fourth side surface facing the fourth side of the to-be-punched structure 4, and the fourth side surface can abut against the side wall of the groove 10. Through the fixation of the fixed block 2 and the clamping block 3, the to-be-punched structure 4 is fixed in full freedom, and the problem of movement of the to-be-punched structure 4 does not occur in the punching process, and the punching precision is ensured.

[0033] The bottom surface of the groove 10 is provided with a discharge hole 101. The waste generated after punching is separated from the workbench 1 through the discharge hole 101.

[0034] The punching tool further comprises a collecting mechanism 11 located below the discharge hole 101. The waste falling from the discharge hole 101 is directly collected in the collecting mechanism 11, facilitating the disposal of the waste by workers.

Based on the above-mentioned description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments cannot be enumerated.
