[0005] The device uses friction to limit the aluminum row, and the positioning structure of the aluminum row needs to resist the torque brought by the drill rod during the drilling process. This application aims to provide a drilling positioning device for aluminum row to improve the positioning stability and thus improve the drilling accuracy. Summary of the invention

[0006] The utility model provides a drilling positioning device for an aluminum bar, which can improve the stability of positioning and thus enhance the accuracy of drilling.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A punching and positioning device for an aluminum bar comprises a positioning base plate, a fixed plate, a through-drilling hole and a movable plate. The movable plate is driven by a driving structure. The driving structure comprises a screw rod, a slider turntable and a motor. The driving shaft of the motor is connected to the slider turntable through transmission. The slider turntable and the screw rod are coaxially arranged and threadedly connected. The end of the screw rod is fixedly connected to the movable plate. The rotating slider turntable drives the screw rod to feed, thereby driving the movable plate to approach or move away from the fixed plate.

[0009] The positioning base plate carries the aluminum bar and the punching positioning components. The fixed plate is fixedly connected to the positioning base plate and is used to abut the aluminum bar. The movable plate is movable. When it abuts against the aluminum bar, the movable plate is arranged on the other side of the aluminum bar away from the fixed plate. Through the abutment between the fixed plate and the movable plate, the torque brought to the aluminum bar by the drill rod tool when drilling can be effectively resisted.

[0010] The driving structure of the present application adopts a screw-slider to realize the feeding of the movable plate. Specifically, since the movable plate and the positioning base plate are attached and cannot rotate relative to each other, when the motor drives the slider turntable, the slider turntable rotates relative to the screw. Since the position of the slider turntable itself is restricted, it cannot move axially along the screw. Because the movable plate is attached to the positioning base plate, when the slider turntable rotates, the screw feeds axially, driving the movable plate to approach or move away from the fixed plate, thereby loosening or fixing the aluminum bar and completing the positioning work of punching holes in the aluminum bar.

[0011] The fixed plate and the movable plate can fully abut against two opposite surfaces of the aluminum row, thereby being able to resist torque, improve positioning stability, and thus improve drilling accuracy.

[0012] Preferably, the positioning bottom plate is further provided with a guide plate, a guide rod is provided between the guide plate and the fixed plate, the guide rod is located on the left and right sides of the fixed plate, and the movable plate is slidably connected to the guide rod. The movable plate is guided and positioned by the guide rod to limit rotation.

[0013] As an advantage, it also includes a turntable positioning block, which is symmetrically arranged on both sides of the slider turntable, and the turntable positioning block is rotatably connected to the slider turntable. The structure is used to realize the positioning of the slider turntable and limit its movement along the axial direction of the screw rod.

[0014] Preferably, the through-drilling hole is an oblong hole. The structure is used to pass the drill rod and generate debris through the drilling hole.

[0015] Preferably, the driving shaft of the motor is fixedly connected with a driving gear, and the driving gear is meshed with the slider turntable, and the driving is achieved through the cooperation of the gear pair.

[0016] Preferably, the driving shaft of the motor is fixedly connected to a driving pulley, the driving pulley and the slider turntable are connected via a belt transmission, and the driving is achieved through the cooperation of the pulley and the belt.

[0017] Preferably, a dovetail strip opened along the length direction is provided on the surface of the positioning base plate, a guide groove is provided on the bottom of the movable plate, and the dovetail strip is inserted into the dovetail groove and slidably connected with the dovetail strip.

[0018] Preferably, the motor is a stepper motor to achieve precise control.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] (1) The torque generated by the drill pipe on the aluminum row is resisted by the movable plate and the fixed plate abutting against the side wall of the aluminum row;

[0021] (2) In addition to loosening and positioning the aluminum bars, the feed of the movable plate can also be used to adapt to aluminum bars of different specifications;

[0022] (3) The screw-slider pair formed by the screw-slider turntable has a self-locking ability to prevent the movable plate from loosening and releasing the positioning of the aluminum row under torque and vibration. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Example:

[0034] A punching and positioning device for aluminum bars, reference Figure 1 , 2 As shown, it includes a positioning base plate 1, a fixed plate 2, a through-drilling hole 3 and a movable plate 4. The movable plate 4 is driven by a driving structure. The driving structure includes a screw 5, a slider turntable 6 and a motor 7. The driving shaft of the motor 7 is connected to the slider turntable 6. The slider turntable 6 and the screw 5 are coaxially arranged and threadedly connected. The end of the screw 5 is fixedly connected to the movable plate 4. The rotating slider turntable 6 drives the screw 5 to feed, thereby driving the movable plate 4 to move closer to or away from the fixed plate 2.

[0035] A guide plate 8 is also provided on the positioning base plate 1, and a guide rod 9 is provided between the guide plate 8 and the fixed plate 2, and the guide rod 9 is located on the left and right sides of the fixed plate 2, and the movable plate 4 is slidably connected to the guide rod 9. The movable plate 4 is guided and positioned by the guide rod 9 to limit rotation. The movable plate 4 has a guide hole through which the guide rod 9 passes, and the guide rod 9 passes through the guide hole and is slidably connected to the guide hole.

[0036] In some possible embodiments, the surface of the positioning base plate is provided with a dovetail strip 12 opened along the length direction, and the bottom of the movable plate is provided with a guide groove 13, and the dovetail strip 12 is inserted into the guide groove 13 and slidably connected with the guide groove 13. The main function of the dovetail strip 12 is to facilitate the movable plate 4 to move on the positioning base plate 1.

[0037] The structure further includes a turntable positioning block 10, which is symmetrically arranged on both sides of the slider turntable 6, and the turntable positioning block 10 is rotatably connected to the slider turntable 6. The structure is used to realize the positioning of the slider turntable 6 and limit its movement along the axial direction of the screw rod 5. The turntable positioning block 10 is rotatably connected to the slider turntable 6 through a bearing and provides a limit in the axial direction.

[0038] The through-drill hole 3 is an oblong hole. The structure is used to generate debris through the drill rod and through the through-drill hole 3. The motor 7 is a stepping motor 7 to achieve precise control.

[0039] In some embodiments, the driving shaft of the motor 7 is fixedly connected to a driving gear, which meshes with the slider turntable 6, and the driving is achieved through the cooperation of the gear pair. In other embodiments, the driving shaft of the motor 7 is fixedly connected to a driving pulley 11, and the driving pulley 11 and the slider turntable 6 are connected through a belt drive, and the driving is achieved through the cooperation of the pulley and the belt.

[0040] The positioning base plate 1 carries the aluminum bar and the punching positioning components. The fixed plate 2 is fixedly connected to the positioning base plate 1 and is used to abut the aluminum bar. The movable plate 4 is movable. When it abuts against the aluminum bar, the movable plate 4 is arranged on the other side of the aluminum bar away from the fixed plate 2. Through the abutment between the fixed plate 2 and the movable plate 4, the torque brought to the aluminum bar by the drill rod tool when drilling can be effectively resisted.

[0041] The driving structure of the present application adopts a screw 5-slider to realize the feeding of the movable plate 4. Specifically, since the movable plate 4 is attached to the positioning base plate 1 and cannot rotate relative to each other, when the motor 7 drives the slider turntable 6, the slider turntable 6 rotates relative to the screw 5. Since the position of the slider turntable 6 itself is limited, it cannot be displaced axially along the screw 5. Because the movable plate 4 is attached to the positioning base plate 1, when the slider turntable 6 rotates, the screw 5 feeds axially, driving the movable plate 4 to approach or move away from the fixed plate 2, thereby loosening or fixing the aluminum bar and completing the positioning work of punching holes in the aluminum bar.

[0042] The fixed plate 2 and the movable plate 4 can fully abut against two opposite surfaces of the aluminum row, thereby being able to resist torque, improve positioning stability, and thus enhance drilling accuracy.

[0043] The use of this device is as follows:

[0044] The guide rod 9 is fixedly connected through the guide plate 8 and the fixed plate 2, so that the movable plate 4 is inserted into the guide rod 9 to achieve guidance.

[0045] The motor 7 is used to drive the driving pulley 11 or the driving gear to rotate, and then the transmission is connected to the slider turntable 6. The slider turntable 6 is positioned by the two turntable positioning blocks 10 and can only rotate. Since the screw rod 5 is fixed to the movable block and cannot rotate synchronously, the screw rod 5 rotates relative to the slider turntable 6, and the screw rod 5 moves forward or backward, thereby driving the movable plate 4 to move, thereby positioning the aluminum row close to the fixed plate 2, or releasing the aluminum row away from the fixed plate 2.

[0046] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
