Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model discloses a location punching device, as shown in fig. 1, location punching device 3 includes tool 2, fixed bolster 31, first actuator 32, clamp plate 33, second actuator 34, first elastic component 35 and drift 36, and first actuator 32 sets up on fixed bolster 31, and the clamp plate setting is in the top of support 2 to be connected with first actuator 32, first actuator 32 can be the cylinder, and it drives the vertical removal of clamp plate 33. The punch 36 is arranged at one side of the jig 2 and corresponds to the opening arranged at one side of the product 7, the punch 36 is arranged in the punch sleeve 37, and the outer wall of the punch 36 is flexibly connected with the inner wall of the punch sleeve 37 through the first elastic piece 35, so that the punch 36 can be finely adjusted in the radial direction; the first elastic member 35 may be a spring or a rubber ring. Prevent to appear the dislocation when die-cut because the overall dimension changes is caused in the shrink of product 7, damage product 7. The punch sleeve 37 is connected to the second actuator 34, and the second actuator 34 may be an air cylinder, and the air cylinder drives the punch sleeve 37 to move horizontally, thereby driving the punch 36 to move toward the side hole of the product 7. The side holes of the product 7 are deburred.

Product 7 is placed on tool 2, can't guarantee that placing at every turn of product 7 is all in place, in order to make product 7 can carry out the accurate positioning when the burring, sets up two parallel locating pins 38 on clamp plate 33, and two through-holes phase-matchs on locating pin 38 and the product 7. During processing, the first actuator 32 drives the pressing plate 33 to press down, the positioning pin 38 is firstly contacted with the through hole, the product 7 is horizontally limited through the positioning pin 38, and then the product 7 is vertically limited through the pressing plate 33. The stability of the product 7 can be maintained during the deburring of the punched hole. Preferably, the lower end of the positioning pin 38 is provided with a 45 ° chamfer, and by this structure, when the product 7 is dislocated, the product 7 can enter the through hole through the end part first, and then the product 7 is corrected and positioned.

When the positioning and punching device 3 is used, a product 7 is placed into the jig 2, the positioning pin 38 is inserted into the through hole of the product 7 through the first actuator 32, and then the pressing plate 33 continues to press downwards to fix the product 7; then, the punch 36 is pushed by the second actuator 34 to move toward the side hole, the side hole is burred, and the punch 36 is finely adjusted by the first elastic member 35. After punching is completed, the second actuator 34 is reset, and then the first actuator 32 brings the pressing plate 33 to reset.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
