[0036] Among them, the outer periphery of the screw member 152 is provided with an extension piece, so that the operator can conveniently rotate the screw member 152.

[0037] Please refer to Figure 1 In this embodiment, the side of the mounting table 11 is provided with a connecting plate 18, the positioning profile 14 is a profile to be punched, and the positioning mechanism for punching the profile further comprises a support frame 17, one end of the positioning profile 14 is fixedly connected with the connecting plate 18, and the other end of the positioning profile 14 is located on the support frame 17.

[0038] Specifically, the connecting plate 18 is an L-shaped structure, the connecting plate 18 comprises a first plate body 181 and a second plate body 182, the first plate body 181 is parallel to the side of the mounting table 11, and the second plate body 182 is perpendicular to the side of the mounting table 11, the second plate body 182 is provided with a threaded hole, the second plate body 182 is supported below the positioning profile 14, and a screw is threadedly connected with the threaded hole on the second plate body 182 through the hole 141 on the positioning profile 14, so as to form a fixed connection between the positioning profile 14 and the mounting table 11.

[0039] The first plate body 181 in the embodiment can be welded with the side of the mounting table 11.

[0040] Please refer to Figure 1 In the embodiment, the second positioning member 16 is a positioning block 161 and a plug post 162 arranged on one side of the positioning block 161, the plug post 162 is inserted into the hole 141 made in the positioning profile 14, and the positioning block 161 is located on the top surface of the positioning profile 14. By positioning the block 161 and the profile, the position of the block 161 is changed to change the positioning position of the profile.

[0041] Please refer to Figure 2 In the embodiment, the positioning mechanism for punching holes in the profile further includes a frame block 19 arranged on the mounting table 11, and the frame block 19 is located between the support guide rod 12 and the positioning profile 14.

[0042] The frame block 19 is provided with a fixing hole 191 for fixing the profile and an avoidance hole 192 for the punch 1A1 of the punching device 1A to pass through the fixing hole 191 and the external space, and the support guide rod 12 extends into the fixing hole 191 and is used for inserting into the profile. The profile can be stably fixed by the frame block 19, and higher punching quality can be obtained.

[0043] The fixing hole 191 is provided with a mounting groove 1911 on the inner wall surface of the two opposite walls, and a guide wheel 1C is arranged in the mounting groove 1911, and the circumferential surface of the guide wheel 1C protrudes from the inner wall surface of the fixing hole 191. The guide wheel 1C is in contact with the side surface of the profile, which can form extrusion fixation of the profile and facilitate the movement of the profile in the fixing hole 191.

[0044] In addition, the frame block 19 is provided with a connecting hole 193, and a scale rod 1B is slidably arranged in the connecting hole 193, one end of the scale rod 1B is rotatably provided with a scale head 1B1, and the scale head 1B1 feeds back the punching interval of the profile inserted into the fixing hole 191. The upward rotation of the scale head 1B1 can avoid interference with the movement of the profile, and the downward rotation of the scale head 1B1 can make it close to the profile to feed back the position of the profile movement, so that the profile can be punched after moving a set interval.

[0045] The extension size of the scale rod 1B relative to the frame block 19 can be measured by an external ruler, or a scale can be directly arranged on the scale rod 1B, and the extension size of the scale rod 1B relative to the frame block 19 can be used to feed back the distance of each movement of the profile.

[0046] Need to explain, when the profile is punched, the first positioning piece 15 or the second positioning piece 16 can be used to contact the profile for fine positioning and punching, or the ruler head 1B1 can be used to calibrate the position of the profile for punching, but the length of the ruler rod 1B is limited, and it is suitable for punching the profile of a shorter length specification.

[0047] The working principle of the utility model: when punching the shorter profile, the profile is inserted into the supporting guide rod 12, and the punching starts from the end of the profile away from the operator, the frame block 19 and the guide wheel 1C inside the frame block 19 can well form positioning and fixing of the profile, and also facilitate the movement of the profile. Then the position of the first positioning piece 15 is moved and adjusted, the profile is pushed to contact the first positioning piece 15 and stopped, and then the profile is punched by the stamping device.

[0048] After one-time pushing of the profile and punching, the position of the first positioning piece 15 is adjusted, the profile is pushed to contact the first positioning piece 15 and stopped for punching operation, and the above operation is repeated until the whole punching work is completed.

[0049] When punching the longer profile, the first positioning piece 15 is located on the side of the stamping device 1A away from the operator, and the profile is longer, so it is not convenient to adjust the position of the first positioning piece 15 and not convenient to position and punch by pushing the profile. At this time, the profile can be inserted into the supporting guide rod 12 for a long distance at one time, and the punching starts from the end of the profile close to the operator. The frame block 19 and the guide wheel inside the frame block 19 can well form positioning and fixing of the profile, and also facilitate the movement of the profile.

[0050] Then the position of the second positioning piece 16 is moved and adjusted, the profile is pulled to contact the second positioning piece 16 and stopped, and then the profile is punched by the stamping device. The suction tool such as the electric vacuum chuck can be used to suck the profile, and then the profile is pulled to move.

[0051] After one-time pulling of the profile and punching, the position of the second positioning piece 16 is adjusted, the profile is pulled to contact the second positioning piece 16 and stopped for punching operation, and the above operation is repeated until the whole punching work is completed.

[0052] The positioning mechanism for profile punching of the preferred embodiment can position the profile for multiple times by moving the position of the first positioning piece when pushing the shorter profile for punching at multiple positions. And the profile is shorter, and the operator does not need to move a long distance to move the first positioning piece.

[0053] By detachable setting the second positioning member on the positioning profile, when the longer profile is pulled to punch in multiple positions, the profile can be positioned multiple times by changing the position of the second positioning member on the positioning profile, the compatibility of the punching positioning is high, and the use cost of the equipment is low.

[0054] In summary, although the utility model has disclosed above with preferred embodiments, the above preferred embodiments are not used to limit the utility model, ordinary skilled in the art can make various changes and decorations without departing from the spirit and scope of the utility model, therefore the protection scope of the utility model is the range defined by the claims.
