Description

Technical Field

[0001] The utility model belongs to the technical field of construction equipment, and specifically relates to an ALC inner wall board wire box punching device. Background Art

[0002] Using ALC boards to construct building interior wall panels in a modular manner has the advantages of being lightweight, fireproof, soundproof, and heat-insulating. However, the integrated wiring of the room is designed and laid out based on the needs of the homeowner, and it is difficult to reserve wire ducts during the production of ALC boards. After the ALC board is installed, an electric water drill is generally used to drill holes as the installation slots for the wire boxes.

[0003] To prevent the ALC board from being drilled through, the drilling depth of the electric water drill needs to be limited. The limiting process is to pre-cut a shallow groove on the edge of the wire box slot, insert a positioning plate to support the positioning box, so that the drill bit is located inside the positioning box, and the drive shaft of the drill bit passes through the positioning box along the casing, and the drive shaft is driven to rotate by the external drilling rig. The outside of the positioning box uses a scale to monitor the drilling rig's advancement depth.

[0004] When the positioning box is used to limit the drill bit, a circular hole is opened in the middle of the positioning box to facilitate the transmission shaft to advance along the circular hole and rotate at the same time. However, the circular hole of the positioning box also limits the activity range of the drill bit. The drill bit can only advance or withdraw, so that the drill bit only drills a circle. The larger plate remaining in the punched circle is not easy to clean. For this reason, we propose an ALC inner wall panel box punching device. Utility Model Content

[0005] The purpose of the utility model is to provide an ALC inner wall panel wire box punching device, which changes the punching position along a circular path, can punch a plurality of mutually intersecting holes in the positioning box, and reduces the difficulty of cleaning the residual plate in the wire box installation groove.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A device for punching a wire box of an ALC inner wall panel comprises a positioning box, one end of the positioning box is an open structure, the other end of the positioning box is axially provided with a middle hole, a slider is slidably installed on the inner wall of the middle hole, a support bearing is fixed on the side of the slider away from the positioning box, the central axis of the support bearing is parallel to the central axis of the middle hole, a transmission shaft is axially inserted into the inner ring of the support bearing, one end of the transmission shaft extends into the interior of the positioning box, a drill bit is fixed on the end of the transmission shaft extending into the interior of the positioning box, the width of the drill bit is smaller than the depth of the positioning box, when punching a hole in the wire box, a cutting machine is used to cut shallow grooves at the edge of the punching position, and the opening of the positioning box is inserted into these grooves To get support, start the electric water drill and rotate the drill bit, push the transmission shaft and the drill bit along the axial direction of the support bearing until the drill bit begins to contact the ALC board, record the exposed length of the transmission shaft as the initial length HI, and then continue to advance. At this time, the exposed length of the transmission shaft is HII, and the drilling depth is △H=HI-HII. When △H reaches the specified range, the first hole is drilled, and the drilling can be stopped to drive the support bearing, transmission shaft and drill bit to stagger the first hole. Repeat the above process and change the drilling position along the circular path. Several intersecting holes can be drilled in the positioning box to cut the plates on the circular path into small pieces, reducing the difficulty of cleaning the residual plates in the installation groove of the wire box.

[0008] The inner edge of the positioning box opening is provided with a plurality of pins distributed in a circular array, the central axes of the pins are parallel to the central axis of the middle hole, and the pins are cylindrical. In this way, the card slot cutting by the cutting machine can be replaced by drilling with an electric drill, and the drilling must be adapted to the pins, making the operation less difficult.

[0009] A scale is fixed on the outside of the positioning box, and the central axis of the scale is parallel to the central axis of the transmission shaft. The scale can be used as a reference to compare with the length of the transmission shaft exposed outside, so as to conveniently measure ΔH, HI and HII.

[0010] The inner ring of the support bearing is also axially fixed with a guide tube, which is sleeved on the outside of the transmission shaft. The inner diameter of the guide tube is closer to the outer diameter of the transmission shaft, can rotate with the transmission shaft, and straighten the transmission shaft to reduce the degree of skewness of the transmission shaft.

[0011] Two baffles are sleeved on the outside of the transmission shaft at a position outside the positioning box. The two baffles are both fan-shaped. The two baffles slide along the outside of the transmission shaft to the specified position. The two ends of the two baffles are tightened with screws until the drill bit drills into △H. The two baffles just resist the guide tube for limiting, forcibly stopping the drill bit from advancing.

[0012] Oil-absorbing felt is fixed at both ends of the slider. Since a lot of sand and ash are blown away during the grinding process, the sand and ash gather in the middle hole and easily cause jamming. Sufficient lubricating oil can be dripped onto the oil-absorbing felt, and the slider is pushed to drive the oil-absorbing felt to rotate several circles in the middle hole, and the lubricating oil is applied to the inner wall of the middle hole for lubrication.

[0013] The technical effects achieved by this utility model are:

[0014] The utility model discloses a device for punching a wire box of an ALC inner wall plate. When punching a wire box, a cutting machine is used to cut shallow slots at the edge of the punching position, and the opening of the positioning box is inserted into the slots to obtain support. After starting the electric water drill, the drill bit is rotated to push the transmission shaft and the drill bit along the axial direction of the support bearing until the drill bit begins to contact the ALC board, and the length of the transmission shaft exposed to the outside is recorded as the initial length HI. Then the drill bit continues to advance. At this time, the length of the transmission shaft exposed to the outside is HII, and the punching depth is △H=HI-HII. When △H reaches a specified range, the first hole is drilled, and the punching can be stopped to drive the support bearing, the transmission shaft and the drill bit to stagger the first hole. The above process is repeated, and the punching position is changed along the circular path. A plurality of holes intersecting with each other can be punched in the positioning box, so that the plate on the circular path is cut into small pieces, thereby reducing the difficulty of cleaning the residual plate in the installation groove of the wire box.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-4As shown, a device for punching a box of an ALC inner wall panel includes a positioning box 1, one end of the positioning box 1 is an open structure, and the other end of the positioning box 1 is axially provided with a middle hole 2, a slider 3 is slidably installed on the inner wall of the middle hole 2, a support bearing 4 is fixed on the side of the slider 3 away from the positioning box 1, the central axis of the support bearing 4 is parallel to the central axis of the middle hole 2, a transmission shaft 5 is axially inserted into the inner ring of the support bearing 4, one end of the transmission shaft 5 extends into the interior of the positioning box 1, and a drill bit 6 is fixed on the end of the transmission shaft 5 extending into the interior of the positioning box 1, and the width of the drill bit 6 is smaller than the depth of the positioning box 1. Several ALC panels are assembled inside the building, and ink lines are drawn on the designated ALC panels according to the construction drawings to indicate the wiring. When punching the box, a cutting machine is used to cut shallow grooves on the edges of the punching positions, and the opening of the positioning box 1 is inserted into these grooves to obtain support, so that the middle hole 2 and the drill bit 6 are vertical. 4, and then the drill bit 6 is rotated to push the transmission shaft 5 and the drill bit 6 axially along the support bearing 4 until the drill bit 6 begins to contact the ALC board. The length of the transmission shaft 5 exposed to the outside is recorded as the initial length HI. Then the electric water drill is pushed to drive the drill bit 6 to continue to advance. At this time, the length of the transmission shaft 5 exposed to the outside is HII, and the drilling depth is △H=HI-HII. When △H reaches the specified range, the first hole is drilled. The drilling can be stopped, the drill bit 6 is removed, and the slider 3 is slid along the inner side of the middle hole 2 to drive the support bearing 4, the transmission shaft 5 and the drill bit 6 to stagger the first hole. Repeat the above process and change the drilling position along the circular path. A number of intersecting holes can be punched in the positioning box 1 to cut the plate on the circular path into small pieces, thereby reducing the difficulty of cleaning the residual plate in the installation groove of the wire box.

[0023] The shape of the positioning box 1 is not limited to a square shape, and a cylindrical shape can be selected. It is only necessary to limit the drill bit 6 to always be located inside the positioning box 1 when changing its position along the circular path. The drill bit 6 and the positioning box 1 will not contact each other, and even if the transmission shaft 5 contacts the inner ring of the support bearing 4, it will only drive the inner ring to rotate, and will not grind the support bearing 4.

[0024] like Figure 1 and Figure 2 As shown, the inner edge of the opening of the positioning box 1 is distributed with a plurality of pins 7 along a circular array, and the central axis of the pins 7 is parallel to the central axis of the middle hole 2, and the pins 7 can all be cylindrical, so that the card slot cutting by the cutting machine can be replaced by drilling with an electric drill, and the drilling must be adapted to the pins 7, which makes the operation less difficult and the depth controllable.

[0025] like Figure 1 and Figure 4As shown, a scale ruler 8 is fixed on the outside of the positioning box 1, and the central axis of the scale ruler 8 is parallel to the central axis of the transmission shaft 5. The scale ruler 8 can be used as a reference to compare with the length of the transmission shaft 5 exposed to the outside, so as to facilitate the measurement of △H, HI and HII. The scale ruler 8 is always staggered with the electric water drill to avoid collision between the two.

[0026] like Figure 1 , Figure 3 and Figure 4 As shown, the inner ring of the support bearing 4 is also axially fixed with a guide tube 9, which is sleeved on the outside of the transmission shaft 5. The inner diameter of the guide tube 9 is closer to the outer diameter of the transmission shaft 5, and can rotate with the transmission shaft 5 to straighten the transmission shaft 5 and reduce the degree of skewness of the transmission shaft 5.

[0027] like Figure 1 and Figure 3 As shown, two baffles 10 are sleeved on the outside of the transmission shaft 5 and located outside the positioning box 1. The two baffles 10 are both fan-shaped. The two baffles 10 slide along the outside of the transmission shaft 5 to the specified position. The two ends of the two baffles 10 are tightened with screws until the drill bit 6 drills into △H. The two baffles 10 just abut against the guide tube 9 for limiting, forcibly stopping the drill bit 6 from advancing.

[0028] like Figure 1 and Figure 4 As shown, oil-absorbing felt 11 is fixed at both ends of the slider 3. Since a lot of sand and ash are blown away during the grinding process, the sand and ash gather in the middle hole 2 and easily cause jamming. Sufficient lubricating oil can be dripped into the oil-absorbing felt 11, and the slider 3 is pushed to drive the oil-absorbing felt 11 to rotate several circles in the middle hole 2, and the lubricating oil is applied to the inner wall of the middle hole 2 for lubrication.

[0029] The working principle of the utility model is as follows: when punching holes in the wire box, a cutting machine is used to cut shallow grooves on the edge of the punching position, and the opening of the positioning box 1 is inserted into these grooves to obtain support, so that the middle hole 2 and the drill bit 6 are perpendicular to the ALC board, and then the exposed end of the transmission shaft 5 is connected to the electric water drill, and the drill bit 6 is rotated after the electric water drill is started, and the transmission shaft 5 and the drill bit 6 are pushed axially along the support bearing 4 until the drill bit 6 begins to contact the ALC board, and the exposed length of the transmission shaft 5 is recorded as the initial length HI, and then the electric water drill is pushed to drive the drill bit 6 to continue to advance. At this time, the exposed length of the transmission shaft 5 is HII, and the punching depth is △H=HI-HII, so that △H reaches the specified range, that is, the first hole is opened.

[0030] At this time, the drilling can be stopped, the drill bit 6 can be removed, and the slider 3 can be slid along the inner side of the middle hole 2 to drive the support bearing 4, the transmission shaft 5 and the drill bit 6 to stagger the first hole. The above process can be repeated, and the drilling position can be changed along the circular path. A number of intersecting holes can be punched in the positioning box 1, so as to cut the plates on the circular path into small pieces, reducing the difficulty of cleaning the residual plates in the installation groove of the wire box.

[0031] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
