DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figures 1 to 5 As shown, a duct rubber pad punching machine includes: a bracket 1, a drill 2, a connecting plate 3 and a positioning rod 4; the bracket 1 is detachably mounted on the convex edge of the duct; the bracket 1 includes a U-shaped plate 1.1 and an L-shaped plate 1.2, and the top end of the L-shaped plate 1.2 is fixedly connected to the bottom end of the U-shaped plate 1.1; the drill 2 is slidably mounted on the bracket 1 in the height direction; the connecting plate 3 and the drill 2 are slidably matched in the height direction, and the connecting plate 3 is slidably mounted in the bracket 1; the top end of the positioning rod 4 is fixedly mounted on the bottom surface of the right end of the connecting plate 3, and the positioning rod 4 can be inserted into the hole that has been punched in the rubber pad.

[0024] When drilling holes in the rubber pad, place the L-shaped plate 1.2 close to the ground of the convex edge, and place the U-shaped plate 1.1 on the top of the convex edge to complete the installation of the bracket 1. When drilling the first hole, manual positioning is required. After the first hole is drilled, pull the bracket 1 to move on the convex edge. When the positioning rod 4 moves to the hole that has been drilled on the rubber pad, the positioning rod 4 is inserted into the hole and drives the connecting plate 3 to move downward. The drill rig 2 is restricted by the connecting plate 3 and cannot continue to move. At this time, it means that there is a hole that needs to be drilled under the drill rig 2. At this time, the drill rig 2 is pressed down to drill the rubber pad. When the rubber pad is drilled, the drill rig 2 is lifted, and the positioning rod 4 is pulled out from the inside of a hole that has been drilled on the rubber pad, and the bracket 1 is moved as a whole, so that the drill rig 2 moves to the next position where a hole needs to be drilled.

[0025] A slider 5 is detachably mounted at the end of the drilling rig 2, and the slider 5 is slidably mounted on the bracket 1. A pressing cylinder 5.1 is provided below the slider 5, and the pressing cylinder 5.1 is sleeved outside the drill bit of the drilling rig 2. A spring 5.2 is fixedly connected between the pressing cylinder 5.1 and the slider 5, and the spring 5.2 is sleeved outside the drill bit of the drilling rig 2.

[0026] Before use, the drill 2 is installed on the slider 5. When the drill 2 moves downward as a whole, it can drive the slider 5 to move downward. The slider 5 drives the pressing cylinder 5.1 on the spring 1 5.2 to move downward. When the pressing cylinder 5.1 contacts the surface of the rubber pad, the drill 2 continues to be pressed down, so that the spring 1 5.2 is compressed. At this time, the pressing cylinder 5.1 is subjected to the elastic force of the spring 1 5.2, and will be close to the rubber pad, pressing the drilling position of the drill 2, so that the drill 2 can be more stable when drilling.

[0027] The slider 5 is arranged inside the U-shaped plate 1.1, and limit blocks 5.3 are fixedly installed at both ends of the slider 5 close to the inner wall of the U-shaped plate 1.1. A slide groove 1.3 is opened at both ends of the U-shaped plate 1.1, and two limit blocks 5.3 are slidably installed in the two slide grooves 1.3 respectively.

[0028] When the drilling rig 2 slides in the height direction, the limit block 5.3 slides in the slide groove 1.3, so that the drilling rig 2 as a whole remains stable when sliding, and the drilling rig 2 can always be kept in a vertical state for use.

[0029] Pressing plates 5.4 are provided at both left and right ends of the pressing cylinder 5.1, and the bottom surfaces of the two pressing plates 5.4 are at the same height as the bottom surface of the pressing cylinder 5.1.

[0030] When the pressing cylinder 5.1 moves, it can drive the pressing plate 5.4 to move. At the same time, when the pressing cylinder 5.1 presses the rubber pad, the pressing plate 5.4 can fit tightly against the rubber pad, so that the drilling rig 2 can be more stable when in use. When the pressing plate 5.4 moves, it can drive the positioning rod 4 to move in the height direction, so that the positioning rod 4 can be pulled out of the drilled hole.

[0031] The top surfaces of the two pressing plates 5.4 are slidably mounted with movable hooks 6, the hook heads of the two movable hooks 6 are facing the positioning rod 4, sliding rods 6.1 are fixedly mounted on both sides of the top of the movable hooks 6, both ends of the U-shaped plate 1.1 are provided with right-angled trapezoidal guide grooves 1.4, the bottom end of the guide groove 1.4 is connected with a straight groove 1.5 toward the side of the positioning rod 4, the sliding rod 6.1 is slidably mounted in the guide groove 1.4, and fixed plates 6.2 are fixedly mounted on both sides of the movable buckle, the fixed plate 6.2 fixes the two movable buckles in connection, and the right end of the fixed plate 6.2 is fixedly connected to the connecting plate 3.

[0032] The oblique groove of the guide groove 1.4 is parallel to the hook head of the movable hook 6, and the fixed plate 6.2 passes through both sides of the pressing cylinder 5.1. The movable hook 6 slides in the straight groove 1.5 through the sliding rod 6.1 and enters the guide groove 1.4, which can drive the fixed plate 6.2 to move in the vertical direction. When the fixed plate 6.2 moves, it can drive the connecting plate 3 to move, so that the positioning rod 4 can be pulled out of the punched hole. When the sliding rod 6.1 slides into the oblique groove of the guide groove 1.4, the positioning rod 4 can be displaced obliquely upward and away from the hole in the horizontal direction. When the sliding rod 6.1 moves to the top of the guide groove 1.4, since the positioning rod 4 is in a suspended state at this time, it will move downward under the action of gravity, and enable the positioning rod 4 to contact the rubber pad. At this time, the sliding rod 6.1 is in the vertical groove on the side of the guide groove 1.4 away from the positioning rod 4. When the positioning rod 4 moves to the top of the hole, it is affected by gravity and falls into the hole to achieve hole positioning. At this time, the sliding rod 6.1 is located at the bottom of the guide groove 1.4. When the drilling rig 2 is pressed down, the sliding rod 6.1 slides in the straight groove 1.5.

[0033] A limiting block 6.3 is fixedly installed at the bottom end of the two movable hooks 6, and a sliding groove 5.7 is opened on the two pressing plates 5.4. The two limiting blocks 6.3 are respectively slidably installed in the two sliding grooves 5.7. A fixing plate 6.4 is fixedly installed on the side of the movable hook 6 away from the positioning rod 4, and a mounting plate 5.5 is fixedly installed on the end of the fixing plate 6.4 away from the movable hook 6, and the bottom end of the mounting plate 5.5 is fixedly connected to the top surface of the pressing plate 5.4.

[0034] When the movable hook 6 slides in the second slide groove 5.7 through the second limit block 6.3, the fixed plate 6.4 will be compressed. When the fixed plate 6.4 is reset, the movable hook 6 can be reset.

[0035] The left and right ends of the sliding block 5 are fixedly mounted with fixed hooks 5.6, and the hook heads of the two fixed hooks 5.6 are away from the positioning rod 4, and the fixed hooks 5.6 located on the same side can be mutually engaged with each other.

[0036] When the drilling rig 2 is pressed down, the spring 1 5.2 is compressed and the fixed hook 5.6 is driven to move downward, so that the inclined surface of the fixed hook 5.6 contacts the inclined surface of the movable hook 6. Since the fixed hook 5.6 and the movable hook 6 are squeezed by the inclined surface, the movable hook 6 is moved away from the positioning plug rod 4 and the fixed plate 6.4 is compressed. When the fixed hook 5.6 is smaller than the movable hook 6 in the height direction, the fixed plate 6.4 is reset and the fixed hook 5.6 is engaged with the fixed hook 5.6. At this time, the spring 1 5.2 is in a compressed state.

[0037] When the drilling rig 2 is lifted, the fixed hook 5.6 drives the movable hook 6 to move upward, and drives the positioning rod 4 to move upward and be pulled out of the hole. At this time, the sliding rod 6.1 slides from the straight groove 1.5 into the guide groove 1.4. When the sliding rod 6.1 moves into the inclined groove of the guide groove 1.4, since the inclined groove of the guide groove 1.4 is parallel to the movable hook 6, the movable buckle moves along the inclined groove direction of the guide groove 1.4 and disengages from the fixed hook 5.6. At this time, the sliding rod 6.1 is at the top of the guide groove 1.4 and is acted upon by the spring 5.2 and gravity. The positioning rod 4 moves downward, and the positioning rod 4 contacts the rubber pad. When the bracket 1 is moved, the positioning rod 4 moves to the top of the hole, and the spring 5.2 continues to reset and inserts the positioning rod 4 into the already drilled hole to achieve the positioning effect of the drilling rig 2. At this time, the sliding rod 6.1 is at the bottom end of the guide groove 1.4, and the bracket 1 continues to be moved so that the sliding rod 6.1 slides to the connection between the straight groove 1.5 and the guide groove 1.4. At this time, the drilling rig 2 cannot move, indicating that the positioning of the drilling rig 2 is completed, and the drilling rig 2 is pressed down to make the drilling rig 2 perform a hole drilling operation on the rubber pad.

[0038] Rollers 1.6 are provided on both sides of the U-shaped plate 1.1, and the rollers 1.6 are used for rolling on the rubber pads.

[0039] The roller 1.6 can be provided to facilitate the bracket 1 to slide on the rubber pad and adjust the punching position at the same time.

[0040] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above implementation without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the scope of the present invention.
