Description

Technical Field

[0001] This invention belongs to the field of drilling equipment technology, specifically a drilling device for photovoltaic flexible brackets. Background Technology

[0002] Photovoltaic flexible brackets are mainly made of aluminum alloy, which has advantages such as strong corrosion resistance, light weight and low cost, making them most suitable as brackets for photovoltaic panels. In order to fix the photovoltaic panels and connect them to the installation, photovoltaic flexible brackets usually have multiple sets of mounting holes drilled at equal intervals on their surface. In the existing technology, drilling equipment is mainly used to drill holes in the formed photovoltaic flexible brackets. The working method is: the punching die impacts the bracket vertically downward under the action of the hydraulic cylinder, and the waste material is pushed down to complete the automatic unloading process. However, the drilling equipment generally does not have a simultaneous deburring function, and the bottom of the bracket after drilling will have burrs of varying degrees. These burrs are generally removed in the next independent process, which undoubtedly reduces production efficiency and increases the production cost of photovoltaic flexible brackets. Therefore, this invention designs a drilling equipment for photovoltaic flexible brackets. Summary of the Invention

[0003] The purpose of this invention is to provide a drilling device for photovoltaic flexible brackets to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a drilling device for a photovoltaic flexible bracket, comprising a base, two sets of pushing mechanisms installed on the top of the base for driving workpiece feeding, a top plate installed on the top of the base via a support column, a hydraulic cylinder installed on the top of the top plate, a movable plate fixedly installed on the telescopic end of the hydraulic cylinder, a fixed block fixedly installed on the bottom of the movable plate, a punching die fixedly installed on the bottom of the fixed block, and a grinding mechanism and a support block fixedly installed on the top of the base respectively;

[0005] The grinding mechanism includes a drive motor, the output shaft of which is fixedly mounted with a sleeve. A connecting column and a spring are movably connected inside the sleeve. The connecting column is elastically supported in the sleeve by the spring. A connecting block is fixedly mounted on the top of the connecting column. A grinding block is movably engaged on the top of the connecting block. A limit post is rotatably mounted inside the grinding block through a bearing. The outer surface of the grinding block abuts against the workpiece.

[0006] As a preferred embodiment of the present invention, the top of the support block is provided with a through groove, and the top of the base is also provided with a discharge port that coincides with the through groove. The top of the support block abuts against the workpiece, and the left and right sides of the top of the base are provided with limiting grooves. The two sets of pushing mechanisms are respectively located in the two sets of limiting grooves.

[0007] In a preferred embodiment of the present invention, the pushing mechanism includes a frame, wherein upper rollers and lower rollers are rotatably mounted inside the frame, and a driving assembly is fixedly mounted on the front of the frame. The driving assembly is used to drive the upper rollers and lower rollers to rotate, and the surface of the workpiece rotates and abuts against the upper rollers and lower rollers.

[0008] In a preferred embodiment of the present invention, the grinding mechanism is located between the pusher mechanism and the support block on the left side, and generates upward pressure on the workpiece.

[0009] As a preferred embodiment of the present invention, the top of the sleeve is provided with multiple sets of slots, and the outer surface of the connecting column is fixedly installed with multiple sets of limiting plates, the limiting plates being engaged and adapted with the slots.

[0010] As a preferred embodiment of the present invention, the grinding block has a placement hole at its top, the bearing is fixedly installed at the top inside the placement hole, and the connecting block is interference-fitted with the bottom of the inner wall of the placement hole.

[0011] As a preferred embodiment of the present invention, the punching die moves downward to punch multiple sets of equidistant holes on the upper surface of the workpiece, and the outer surface of the grinding block abuts against the bottom of the inner wall of the hole.

[0012] As a preferred embodiment of the present invention, the inclined angles of the limiting post and the outer surface of the grinding block are the same, the cross-sectional shape of the limiting post is "T" shaped, and a gap is left between the outer edge of the bottom of the limiting post and the top of the grinding block.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. This device incorporates a grinding mechanism, enabling the workpiece to be ground and deburred simultaneously with drilling. Two sets of pushing mechanisms clamp the workpiece and precisely control its movement at each distance. A hydraulic cylinder drives the die downwards to punch holes on the upper surface of the workpiece. When the holes are moved above the grinding mechanism, compressed springs push the connecting column, connecting block, and limiting column upwards through the inner wall of the holes. A drive motor drives the grinding block to rotate at high speed, cleaning the burrs on the inner wall of the holes, thus improving the device's practicality.

[0015] 2. Simultaneously, by fixing a bearing to the top of the inner wall of the placement hole and rotating a limit post, when the drive motor continuously drives the connecting block and grinding block to rotate, the limit post is prevented from being rigidly rotated and causing rotation of the bottom of the workpiece. When the workpiece moves and forces the grinding block and the limit post to leave the inner wall of the hole, so that the top of the limit post abuts against the bottom of the workpiece, the spring's downward rebound force generates friction between the limit post and the solid part of the bottom of the workpiece. In conjunction with the bearing, when the grinding block is driven by the drive motor to rotate at high speed, only the bearing rotates, while the limit post, due to its rotating installation design, is prevented from being rotated along with it, thus avoiding wear on the bottom of the workpiece.

[0016] 3. Finally, by using the top of the support block to provide rigid support for the workpiece, the stress generated by the compression of the solid part around the hole is reduced. In addition, by setting the fixing block, not only can the installation of the die be made threaded and detachable, but also the hydraulic cylinder can drive the fixing block and the die to the height where the bottom of the die can abut against the workpiece. The compression of the workpiece by the die and the support block further helps to eliminate some of the stress in the solid part around the hole. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 9 As shown, this embodiment of the invention provides a drilling device for photovoltaic flexible brackets, including a base 1. Two sets of pushing mechanisms 12 are installed on the top of the base 1. The pushing mechanisms 12 are used to drive the workpiece 11 to feed. A top plate 3 is installed on the top of the base 1 through a support column 2. A hydraulic cylinder 4 is installed on the top of the top plate 3. A movable plate 5 is fixedly installed on the telescopic end of the hydraulic cylinder 4. A fixing block 7 is fixedly installed on the bottom of the movable plate 5. A punch 8 is fixedly installed on the bottom of the fixing block 7. A grinding mechanism 9 and a support block 10 are fixedly installed on the top of the base 1 respectively.

[0029] The grinding mechanism 9 includes a drive motor 91. The output shaft of the drive motor 91 is fixedly mounted with a sleeve 92. A connecting post 93 and a spring 95 are movably connected inside the sleeve 92. The connecting post 93 is elastically supported in the sleeve 92 by the spring 95. A connecting block 96 is fixedly mounted on the top of the connecting post 93. A grinding block 97 is movably engaged on the top of the connecting block 96. A limit post 99 is rotatably mounted inside the grinding block 97 through a bearing 98. The outer surface of the grinding block 97 abuts against the workpiece 11.

[0030] This device incorporates a grinding mechanism 9, enabling the workpiece 11 to be ground and deburred simultaneously while being drilled. Two sets of pushing mechanisms 12 clamp the workpiece 11 and control its precise movement over each distance. A hydraulic cylinder 4 drives the die 8 to punch downwards, creating holes 110 on the upper surface of the workpiece 11. When the holes 110 are moved above the grinding mechanism 9, a compressed spring 95 pushes the connecting column 93, connecting block 96, and limiting column 99 upwards through the inner wall of the holes 110. A drive motor 91 drives the grinding block 97 to rotate at high speed, cleaning the burrs on the inner wall of the holes 110, thus improving the device's practicality.

[0031] Meanwhile, by fixing a bearing 98 to the top of the inner wall of the placement hole 910 and rotating a limiting post 99, when the drive motor 91 continuously drives the connecting block 96 and the grinding block 97 to rotate, the limiting post 99 is prevented from being rigidly rotated and causing rotation of the bottom of the workpiece 11. When the workpiece 11 moves and forces the grinding block 97 and the limiting post 99 to leave the inner wall of the hole 110, so that the top of the limiting post 99 abuts against the bottom of the workpiece 11, the spring 95 generates a downward rebound force to create friction between the limiting post 99 and the solid part of the bottom of the workpiece 11. With the bearing 98, when the grinding block 97 is driven by the drive motor 91 to rotate at high speed, it only drives the bearing 98 to rotate. The limiting post 99, due to its rotating installation design, is prevented from being driven to rotate as well, thus avoiding wear on the bottom of the workpiece 11.

[0032] Among them, the top of the support block 10 is provided with a through groove 13, and the top of the base 1 is also provided with a discharge port 6 that overlaps with the through groove 13. The top of the support block 10 abuts against the workpiece 11. Limiting grooves 14 are provided on both the left and right sides of the top of the base 1. Two sets of pushing mechanisms 12 are respectively located in the two sets of limiting grooves 14.

[0033] The through groove 13 coincides with the hole 110 produced by the punching and has a larger area than the latter. By opening the discharge port 6 on the top of the base 1 and the through groove 13 on the top of the support block 10, when the hydraulic cylinder 4 drives the moving plate 5, the fixed block 7 and the punch 8 to punch and drill the upper surface of the workpiece 11, the top of the support block 10 provides rigid support for the workpiece 11, thereby reducing the stress generated by the compression of the solid part around the hole 110. The fixed block 7 not only makes the installation of the punch 8 threaded and detachable, but also allows the fixed block 7 and the punch 8 to be moved by the hydraulic cylinder 4 to a height where the bottom of the punch 8 can abut against the workpiece 11. The compression of the workpiece 11 by the punch 8 and the support block 10 further helps to eliminate some of the stress in the solid part around the hole 110.

[0034] The feeding mechanism 12 includes a frame 121, with upper rollers 122 and lower rollers 123 rotatably mounted inside the frame 121. A drive assembly 124 is fixedly mounted on the front of the frame 121. The drive assembly 124 is used to drive the upper rollers 122 and lower rollers 123 to rotate, and the surface of the workpiece 11 rotates and abuts against the upper rollers 122 and lower rollers 123.

[0035] The drive assembly 124 consists of a servo motor and a gear transmission mechanism, which are respectively connected to the upper roller 122 and the lower roller 123. The servo motor drives the upper roller 122 and the lower roller 123 to achieve synchronous reverse rotation, thereby pushing the workpiece 11 to move along the transport direction and realizing the precise feeding function of the workpiece 11.

[0036] The grinding mechanism 9 is located between the pusher mechanism 12 and the support block 10 on the left side, and generates upward pressure on the workpiece 11.

[0037] The grinding mechanism 9 is located on the left side of the support block 10, so that the part of the workpiece 11 to be processed just passes through the grinding mechanism 9, thereby facilitating a series of subsequent grinding operations.

[0038] Among them, the top of the sleeve 92 is provided with multiple sets of slots 921, and multiple sets of limiting plates 94 are fixedly installed on the outer surface of the connecting column 93. The limiting plates 94 are engaged and matched with the slots 921.

[0039] The sleeve 92 and the connecting post 93 are rotated synchronously through the limiting plate 94 and the slot 921, and can move relative to each other along their axis. When the grinding block 97 and the limiting post 99 pass through the hole 110, the connecting post 93 is pushed upward by the spring 95, and at the same time, the rotation of the connecting post 93 is not affected.

[0040] The grinding block 97 has a placement hole 910 at its top, the bearing 98 is fixedly installed at the top inside the placement hole 910, and the connecting block 96 is in an interference fit with the bottom of the inner wall of the placement hole 910.

[0041] The placement hole 910 is responsible for placing the bearing 98, so that the limiting post 99 and the grinding block 97 can achieve relative rotation. The bearing 98 can ensure that the power of the drive motor 91 is rigidly transmitted to the limiting post 99, preventing excessive rotational wear of the solid part at the bottom of the workpiece 11 by the limiting post 99.

[0042] Among them, the downward movement of the punch 8 can punch multiple sets of equally spaced holes 110 on the upper surface of the workpiece 11, and the outer surface of the grinding block 97 abuts against the bottom of the inner wall of the hole 110.

[0043] After the holes 110 are punched out, they are linearly and equidistantly distributed on the upper surface of the workpiece 11. The die 8 punches downward and breaks through the surface of the workpiece 11 to achieve the punching and drilling function.

[0044] Among them, the inclined angles of the outer surfaces of the limiting post 99 and the grinding block 97 are the same, the cross-sectional shape of the limiting post 99 is "T" shaped, and there is a gap between the outer edge of the bottom of the limiting post 99 and the top of the grinding block 97.

[0045] The limiting post 99 and the grinding block 97 are combined with each other, and their inclined surfaces are adapted to each other. When entering and exiting the interior of the hole 110, they can smoothly pass through the rotational grinding position of the hole 110 through the integrally formed combined inclined surface.

[0046] Working principle:

[0047] When the device is in operation, the workpiece 11 is inserted along the right-side pushing mechanism 12 and fixed by the upper roller 122 and the lower roller 123. The drive assembly 124 is started and the lower roller 123 and the upper roller 122 are driven to rotate, causing the workpiece 11 to move horizontally along the transport direction. After passing the top of the support block 10, it is supported by the support block 10. When the workpiece 11 is driven to the designated position by the pushing mechanism 12, the pushing mechanism 12 is stopped and the workpiece 11 is put into a stationary state.

[0048] Then, the hydraulic cylinder 4 is activated, which drives the moving plate 5, the fixed block 7 and the punch 8 to move downward, so that the punch 8 penetrates the upper surface of the workpiece 11 and punches out the hole 110 on the upper surface of the workpiece 11. The punched blank is discharged downward along the through groove 13 and the discharge port 6. Subsequently, the punch 8 automatically resets up and down under the contraction of the hydraulic cylinder 4. At this time, the pushing mechanism 12 is activated again and pushes the workpiece 11 along the transport direction. At this time, the grinding mechanism 9 is located below the workpiece 11. During the movement, the workpiece 11 abuts against the outer surface of the limiting post 99 and the grinding block 97, and presses the grinding block 97 downward, which drives the connecting post 93 to move down and compresses the spring 95 to obtain the upward rebound force, ensuring that the limiting post 99 and the bottom of the workpiece 11 can always fit tightly.

[0049] Then, start the drive motor 91 and drive the sleeve 92, limit plate 94, connecting post 93, connecting block 96, grinding block 97 and limit post 99 to rotate. When the limit post 99 is at the bottom of the workpiece 11, the upward abutting pressure generated by the spring 95 causes friction between the limit post 99 and the bottom of the workpiece 11. When the connecting post 93 drives the grinding block 97 to rotate as a whole, the rotation support of the bearing 98 can prevent the limit post 99 and the grinding block 97 from rotating at the same time, reducing the wear and tear on the bottom of the workpiece 11. When the limit post 99 and the grinding block 97 enter the interior of the hole 110, the grinding block 97 uses its outer inclined surface and high-speed rotation to grind and eliminate the burrs located inside and at the bottom of the hole 110.

[0050] Finally, as the pushing mechanism 12 drives the workpiece 11 to continue moving, the grinding block 97 and the limiting post 99 enter the right side of the hole 110 through relative movement, and then disengage from the inside of the hole 110, so that the grinding block 97 abuts against the bottom of the workpiece 11, and so on.
