[0021] See also Figure 1-3 The utility model discloses a steel plate processing punching mechanism, including a positioning mechanism 1, wherein a driving mechanism 2 is arranged on the top of the positioning mechanism 1; a sleeve 11 and a threaded cylinder 12 are fixedly connected to the bottom of the positioning mechanism 1, a sliding rod 13 is slidably connected to the inside of the sleeve 11, a first adjusting bolt 14 is threadedly connected to the inside of the threaded cylinder 12, a pressing plate 15 is fixedly connected to the top of the sliding rod 13, and a sliding groove 16 is opened in the middle of the positioning mechanism 1; a motor group 21 is arranged in the middle of the driving mechanism 2, and the output end of the motor group 21 is fixedly connected to the output end of the motor group 21. A transmission rod 22 is connected, the external thread of the transmission rod 22 is connected to a sliding sleeve 23, a drill bit 24 is inserted at the bottom of the transmission rod 22, a positioning pin 25 is inserted at the side of the transmission rod 22, a slider 26 is fixedly connected to the bottom of the driving mechanism 2, and a bracket 27 is slidably connected to the outside, a through groove 28 is opened on the side of the bracket 27, a second adjusting bolt 29 is arranged inside the through groove 28, a third adjusting bolt 210 is threadedly connected to the tail of the bracket 27, and a knob 211 is transmission-connected to the side of the third adjusting bolt 210.

[0022] Specifically, the sleeve 11 and the threaded cylinder 12 are symmetrically arranged in two groups on the left and right sides of the positioning mechanism 1, each group includes a threaded cylinder 12 and two sleeves 11, the first adjusting bolt 14 passes through the pressure plate 15 and the positioning mechanism 1 and a crank is arranged above the pressure plate 15, and the first adjusting bolt 14 is rotatably connected to the pressure plate 15.

[0023] In this embodiment, two sets of sleeves 11 and threaded tubes 12 are connected to two pressure plates 15 on both sides of the positioning mechanism 1, and cooperate with the table top below the positioning mechanism 1 to clamp and position the steel plate. The two sleeves 11 are respectively connected to two sliding rods 13, which play a directional role in the up and down movement of the pressure plate 15. The first adjusting bolt 14 is rotated by the crank at the top of the first adjusting bolt 14, and the pressure plate 15 is driven to move up and down by the action of the thread.

[0024] Specifically, the front end of the bracket 27 protrudes forward of the positioning mechanism 1, the second adjusting bolt 29 is threadedly connected to the slider 26, the bottom of the bracket 27 is slidably connected to the slide groove 16, and the bottom of the third adjusting bolt 210 is tightly fitted to the inner wall of the slide groove 16.

[0025] In this embodiment, the bracket 27 extends the driving mechanism 2 and its attached drill bit 24 structure toward the front of the positioning mechanism 1, and adjusts the forward extension of the drill bit 24 by sliding the slider 26, thereby adjusting the front and rear positions of the drilling point. During the adjustment process, the second adjusting bolt 29 slides in the through groove 28, and the second adjusting bolt 29 is screwed in so that its nut is in close contact with the side wall of the bracket 27 to increase the friction force, thereby fixing the position of the slider 26. The bracket 27 itself is slidably connected in the slide groove 16, and the left and right positions of the drilling site are adjusted by sliding the bracket 27. In conjunction with the rotation of the third adjusting bolt 210, the height of the third adjusting bolt 210 at the tail of the bracket 27 is changed by the threaded action. When the bottom of the third adjusting bolt 210 is in contact with the slide groove 16, the friction is increased, and vice versa when it is away, thereby positioning the left and right positions of the bracket 27.

[0026] Specifically, a square rod is coaxially connected to the top of the screw portion of the third adjusting bolt 210, the outside of the square rod is slidably connected to the first bevel gear 101, the end of the knob 211 is fixedly connected to the second bevel gear 102, the first bevel gear 101 and the knob 211 are respectively rotatably connected to the bracket 27, and the first bevel gear 101 and the second bevel gear 102 are meshed with each other.

[0027] In this embodiment, when the knob 211 is rotated, the second bevel gear 102 rotates accordingly, driving the first bevel gear 101 to rotate, and the first bevel gear 101 drives the third adjusting bolt 210 to rotate through the square rod. Since the third adjusting bolt 210 is threadedly connected to the bracket 27, the height of the third adjusting bolt 210 is changed.

[0028] Specifically, the motor group 21 includes an electric cylinder and a motor. The motor is arranged at the movable end of the electric cylinder. The transmission rod 22 is transmission-connected to the motor output shaft. The connection between the drill bit 24 and the transmission rod 22 is arranged in a square rod shape.

[0029] In this embodiment, the electric cylinder in the motor group 21 drives the motor and the transmission rod 22 connected to its output shaft to move up and down, providing downward pressure during drilling. The motor drives the transmission rod 22 to rotate, and then drives the drill bit 24 to rotate to achieve the drilling action. The specific structure and working principle of the motor group 21 are commonly found in various types of drilling equipment and belong to existing mature technologies, which will not be elaborated here.

[0030] Specifically, the positioning pin 25 passes through the transmission rod 22 and the drill bit 24 . The positioning pin 25 is arranged on the transmission rod 22 in an embedded structure. When the sliding sleeve 23 is at the lowest end, it is nested outside the positioning pin 25 .

[0031] In this embodiment, the transmission rod 22 and the drill bit 24 are connected by plugging, and the insertion of the positioning pin 25 plays a fixing role in the connection between the transmission rod 22 and the drill bit 24, and the sleeve 23 itself is threadedly connected to the transmission rod 22, and its up and down positions are changed by rotating the sleeve 23. When the sleeve 23 moves to the bottom, it plays a positioning role on the positioning pin 25, otherwise it releases the restriction on the positioning pin 25, making it convenient to pull out the positioning pin 25, thereby forming an anti-escape structure on the outside of the positioning pin 25.

[0032] When in use, the positioning mechanism 1 is installed on the desktop, the sleeve 11 and the threaded tube 12 are embedded in the desktop, and hollows corresponding to the sleeve 11 and the threaded tube 12 are set on the desktop. At the same time, the desktop is also hollowed out in the area between the pressure plate 15 in front of the positioning mechanism 1 to provide activity space for the drill bit 24. The steel plate to be processed is clamped between the pressure plate 15 and the desktop, and the first adjusting bolt 14 is turned to press the pressure plate 15 down to fix it. The left and right positions of the drilling holes are changed by sliding the bracket 27 left and right. The knob 211 is rotated to drive the third adjusting bolt 210 to rotate and move downward, and fit closely with the slide groove 16 to fix the position of the bracket 27. The slider 26 is slid forward and backward, and then the second adjusting bolt 29 is screwed in, so that the nut of the second adjusting bolt 29 fits closely with the bracket 27, and the front and rear positions of the driving mechanism 2 are fixed. The motor group 21 is started to drive the transmission rod 22 to rotate and move up and down, thereby driving the drill bit 24 to complete the drilling action.

[0033] When the drill bit 24 needs to be replaced, the motor group 21 drives the drill bit 24 to move to the highest point and stop, rotates the sleeve 23 to move it upward, exposes the positioning pin 25, pushes the positioning pin 25 from one side of the transmission rod 22 to push it out and pull it out, contacts the lock of the drill bit 24, pulls out and replaces the drill bit 24, re-bolts the positioning pin 25, rotates the sleeve 23 to move it downward, and tightens the sleeve 23 to complete the replacement work.

[0034] To sum up, the steel plate processing and punching mechanism, by setting the slide groove 16, the bracket 27 and the slider 26, constitutes two horizontal and vertical sliding structures, which play a role in adjusting the projection point position of the drill bit 24 on the steel plate, and the positioning pin 25 is set to fix the connection between the drill bit 24 and the transmission rod 22, and the sliding sleeve 23 is set to fix the position of the positioning pin 25. The drill bit 24 locking structure composed of the two is simple and easy to operate, which improves the convenience of replacing the drill bit 24. The combination of the two improves the convenience of adjusting the punching equipment.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
