Description

Technical Field

[0001] The utility model relates to the technical field of plate hole punching equipment, in particular to a proofing and punching equipment. Background Art

[0002] During the production process, some holes cannot be drilled due to the limitation of the workpiece structure, so manual hole marking is usually used. First, the workpiece is positioned, and the hole position is marked with a stylus. After the workpiece is removed, the hole center is measured according to the marking line and a sample punching point is made, and the hole is drilled according to the sample punching point. Manual hole marking not only has poor accuracy but also low efficiency.

[0003] Through searching, we found the Chinese patent document with patent number CN215660223U. Although it solves the problem of difficulty in centering after large hole marking, improves the working efficiency and reduces the occurrence of punching errors, in actual application, the hand-held part is located directly below the hammer's strike, so the user's hand is easily hit by the hammer during use, and the hammer also shakes the user's hand during the strike. Another Chinese patent document with patent number CN216830727U has similar problems. Utility Model Content

[0021] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0022] See also Figure 1-7 The utility model provides an embodiment: a proofing and punching device, comprising a shell 1, a punching needle 2 is slidably installed inside the shell 1, and an impact piece 3 is also provided at the upper end of the shell 1; the impact piece 3 includes an impact hammer 30 sliding inside the shell 1 and an end cover 31 installed at the upper end of the shell 1, and an elastic piece 32 is provided between the impact hammer 30 and the end cover 31; a pull rod 33 is provided in the radial direction of the impact hammer 30, and both ends of the pull rod 33 are located outside the shell 1; the pull rod 33 is used to cause the impact hammer 30 to move upward along the shell 1 to compress the elastic piece 32, and when the external force of the pull rod 33 disappears, the impact hammer 30 quickly hits the punching needle 2 under the action of the elastic piece 32, so that the punching needle 2 forms a punching hole on the surface of the plate. Based on this, the device has a simpler structure while realizing punching, and the impact hammer hits the punching needle 2 inside the shell 1, which protects the user's hands and does not require the use of a hammer, so the vibration generated when the hammer strikes can be reduced. The elastic member 32 is preferably a coil spring.

[0023] Furthermore, since the impact hammer 30 is also provided with a linkage rod 36, and a stop ring 311 is provided at one end of the linkage rod 36; the end cover 31 is also provided with a switch 35, and a through hole 39 is provided in the middle of the switch 35, and a stop pin 38 is provided on the inner wall surface of the through hole 39. Therefore, when the impact hammer 30 slides upward until the stop ring 311 is exposed in the switch 35, and then the stop pin 38 on the switch 35 abuts against the bottom surface of the stop ring 311, the impact hammer 30 can be prevented from automatically hitting the punching needle 2; on the contrary, the stop pin 38 is separated from the stop ring 311, so that the impact hammer 30 can hit the punching needle 2 again.

[0024] Based on this, by utilizing the cooperation between the stop pin 38 and the stop ring 311, the impact hammer 30 can be controlled to hit the punch needle 2 or prevented from hitting the punch needle 2; thereby, the impact hammer 30 after accumulating power can hit the punch needle 2 as needed.

[0025] At the same time, since an avoidance groove 310 is also provided on the circumferential surface of the linkage rod 36, and the avoidance groove 310 is connected to the stop ring 311, when the stop pin 38 enters the avoidance groove 310, the stop pin 38 loses its braking effect. At this time, the elastic member 32 after storing force can prompt the impact hammer 30 to quickly hit the punch needle 2.

[0026] In order to facilitate the assembly of the impact hammer 30 and the housing 1, a connecting portion 312 is further provided at the lower end of the linkage rod 36, and the connecting portion 312 passes through the impact hammer 30 and is connected to the connecting hole 34 provided on the pull rod 33. When the connecting portion 312 passes through the impact hammer 30 and is connected to the connecting hole 34, it can be ensured that the pull rod 33 can stably and reliably cause the impact hammer 30 to slide, and at the same time, the problem that the impact hammer 30 and the pull rod 33 do not slide smoothly inside the housing 1 due to unstable positions can be avoided; wherein, the connecting portion 312 and the connecting hole 34 are preferably connected in a threaded matching manner, for example, the connecting portion 312 is a screw rod, and the connecting hole 34 is an internal threaded hole.

[0027] Furthermore, since the switch 35 is rotatably mounted on the end cover 31, the switch 35 is rotated to rotate the stop pin 38 into the avoidance groove 310. At this time, the stop pin 38 loses its braking ability, and the compressed elastic member 32 can prompt the impact hammer 30 to hit the punching needle 2 to complete the punching action. In addition, when the punching needle 2 is aligned with the punching point, the switch 35 rotates less, which facilitates the punching needle 2 to align with the punching point, thereby reducing the phenomenon of positional deviation of the punching needle 2 during operation due to external interference.

[0028] In addition, since the pull rod 33 is slidably matched with the mounting hole 37 provided in the radial direction of the impact hammer 30, it is convenient to extract the pull rod 33 from the impact hammer 30 or insert the pull rod 33 into the impact hammer 30; when the linkage rod 36 rotates counterclockwise, the connection portion 312 is separated from the connection hole 34, and at this time, the pull rod 33 is pulled outward to separate the impact hammer 30 from the pull rod 33, thereby facilitating the removal of the impact hammer 30 from the housing 1.

[0029] On the basis of the above scheme, since the housing 1 is also provided with a slide groove 4 in the radial direction to guide the sliding of the pull rod 33, the slide groove 4 can be used to guide the impact hammer 30 to slide in a directional manner, so that the stop pin 38 can smoothly contact the stop ring 311.

[0030] Furthermore, since the punch needle 2 contacts the impact hammer 30 through the provided pad 6, the contact surface can be enlarged to avoid the phenomenon that the end of the punch needle 2 is flanging after being hit due to its small diameter; thereby ensuring that the punch needle 2 can slide smoothly inside the shell 1.

[0031] In addition, since a reset member 5 is provided between the cushion block 6 and the facing surface of the housing 1 , the reset member 5 can be used to enable the punching needle 2 to quickly reset after being hit, so that the user can perform the next punching operation.

[0032] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
