Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and specifically to a housing drilling equipment for the production and processing of electronic devices. Background Art

[0002] With the rapid development of technologies such as 5G communication, artificial intelligence, and the Internet of Things, the integration degree of electronic devices has been continuously improved, and the requirements for the accuracy, sealing performance, and light weight of their housings have become increasingly stringent. Drilling, as a key process in housing processing, requires the aperture accuracy to be controlled at the micron level to meet the installation and signal transmission requirements of internal precision components. At the same time, the mass production mode requires the equipment to have high-efficiency automation capabilities to reduce costs and improve production efficiency. In addition, to ensure the waterproof and dustproof performance of electronic products, the quality of the hole wall after drilling, including indicators such as surface roughness and perpendicularity, is also crucial.

[0003] Traditional drilling equipment mostly adopts a rigid mechanical structure and a simple manual or semi-automatic control method. Workers need to position the workpiece four times repeatedly, and then the machine tool drills holes. This process not only takes a lot of time, but also reduces the machining accuracy due to the repeated positioning of the workpiece, thus reducing the qualification rate of the workpiece and making it difficult to meet the processing requirements of high precision and high efficiency. Summary of the Invention

[0005] A drilling assembly, the drilling assembly is fixedly installed inside the protective shell, the drilling assembly is located above the fixing assembly, and on the outside of the protective shell, a motor is fixedly connected, and the output end of the motor is fixedly connected to the drilling assembly;

[0006] A fixing assembly, the fixing assembly is slidably installed on the top of the slide rail;

[0007] Among them, the fixing assembly includes a fixing plate, at the bottom of the fixing plate, a slider is fixedly connected, the slider is slidably connected to the slide rail, and on the top of the fixing plate, a fixing member is fixedly connected;

[0008] The fixing member includes a circular plate, which is fixedly connected to the fixing plate. A through groove is formed at the top of the circular plate, and a screw rod is rotatably connected inside the through groove. The housing to be processed is inverted on the top plate on the top of the circular plate, so that the bottom of the inner wall of the housing contacts the top of the top plate. Subsequently, the driving motor is externally powered to work, so that the driving motor drives the screw rod to rotate. Thus, the screw rod drives the fixing block to move inside the through groove towards the inner wall of the housing, and then the outer sides of the sides of the contact plate are respectively in contact with the side and the bottom edge of the inner wall of the housing. By setting the L-shaped contact plate, the vertical and horizontal planes of the contact plate limit multiple degrees of freedom of the housing to fix the housing, thereby ensuring the position accuracy of the holes. Moreover, the contact area is larger and the clamping force distribution is more uniform, which can effectively prevent the deformation of the housing caused by local stress concentration during drilling. A driving motor is fixedly connected to the outer side surface of the circular plate, the output end of the driving motor is fixedly connected to the screw rod, a fixing block is threadedly connected to the outer side of the screw rod, and a contact plate is fixedly connected to the top of the fixing block.

[0009] A control box is fixedly connected to the end of the protective housing close to the side plate. The control box is located above the side plate. The number of side plates is two, and the two side plates are symmetrically arranged with the fixing component as the center. The number of slide rails is two. After the housing is fixed, the slider moves on the top of the slide rail towards the direction of the drilling component, so that the slider drives the fixing plate and the housing on the top to move to the designated processing position for processing. The two slide rails are symmetrically arranged at both ends of the top of the platform, and the output end of the motor penetrates the protective housing.

[0010] Second Embodiment. On the basis of the first embodiment, please refer to the figures shown. A ring is fixedly connected to the top of the fixing plate. There are two sliders. The ring is sleeved on the outside of the circular plate. A ring groove is formed at the top of the ring. An arc-shaped block is fixedly connected to the inner wall of the ring. The arc-shaped block is located at the interval between the ring and the circular plate. There are three arc-shaped blocks, and the three arc-shaped blocks are evenly distributed on the ring. The housing is inverted on the top of the top plate. At this time, the side of the housing is sleeved on the outside of the top plate. The driving motor works to drive the screw to rotate, so that the screw drives the contact plate through the fixing block to support and fix the inside of the housing. After fixing, the motor is externally powered to work. The motor works to drive the gear to rotate, so that the gear drives the ring to rotate through the tooth block. The ring drives the internal arc-shaped block to rotate, so that the arc-shaped block contacts and squeezes the moving block, so that the moving block moves along the fixed rod inside the square hole towards the top plate. Furthermore, the moving block drives the connecting plate and the arc plate to move. By utilizing the elastic properties of the compression spring and the return spring, the clamping block and the square block are in close contact with the outside of the housing. By setting the internal contact plate and the external clamping block, the internal clamping component fits with the inner wall of the housing to form a stable internal positioning reference to determine the internal position of the housing. The external clamping device applies pressure from the outside and cooperates with the internal clamping force to further fix the position of the housing in space, restrict the movement and rotation of its various degrees of freedom, achieve the all-round positioning of the housing, ensure that the position of the housing is unique and fixed during drilling, meet the processing requirements of high-precision hole positions. A clamping component is arranged on one side of the fixing part close to the ring. A gear is fixedly connected to the top of the fixing plate. A motor is fixedly connected to the bottom of the fixing plate. The output end of the motor penetrates through the fixing plate and extends to be fixedly connected to the middle of the gear. A tooth block is fixedly connected to the outside of the ring close to the gear. The gear is in gear engagement with the ring through the tooth block.

[0011] A top plate is fixedly connected to the middle of the top of the circular plate. The edge of the top of the top plate is inclined. The contact plate is L-shaped. A round hole is formed in the middle of the top of the top plate. There are three through grooves, and the three through grooves are evenly distributed around the top plate. An extension plate is fixedly connected to the top of the outer side of the circular plate. There are three extension plates, and the three extension plates are alternately and evenly arranged with the driving motor. A square hole is formed in the extension plate close to the inside of the circular plate. The clamping component is located inside the square hole. A fixed rod is fixedly connected to the inside of the square hole. The fixed rod is slidably connected to the clamping component. A cylinder is fixedly connected to the bottom of the extension plate close to the ring groove. The motor is externally powered to work. The motor works to drive the gear to rotate, so that the gear drives the ring to rotate through the tooth block, so that the cylinder slides inside the ring groove. By setting the cylinder and the ring groove, the ring groove forms a circumferential and radial constraint on the cylinder. When the cylinder slides along the groove, the movement track can be strictly limited to achieve high-precision linear or circumferential guidance and ensure the accurate relative position of the components. The cylinder is located inside the ring groove.

[0012] The clamping member includes a moving block which is slidably connected to the square hole. The fixed rod passes through the moving block. One side of the moving block close to the circular plate is fixedly connected with an elastic plate, and one end of the elastic plate away from the moving block is fixedly connected with the circular plate. The top of the moving block on the side close to the elastic plate is fixedly connected with a connecting plate. One end of the connecting plate away from the moving block is fixedly connected with an arc plate. The middle part of the side of the arc plate away from the connecting plate is slidably connected with a sliding rod. One end of the sliding rod away from the arc plate is fixedly connected with a clamping block. The clamping block is made of rubber. A return spring is sleeved on the outer side of the sliding rod. By setting the return spring and the compression spring, when the workpiece expands or contracts due to temperature change or the shape of the workpiece slightly changes due to material removal during the processing, the clamping force can be automatically adjusted to avoid the loosening of the workpiece caused by the increase of the gap in the traditional rigid clamping. And during the drilling process, the return spring and the compression spring can attenuate the transmission of the equipment vibration to the workpiece and reduce the machining accuracy deviation caused by the vibration. The two ends of the return spring are respectively fixedly connected with the arc plate and the clamping block. The end face of the arc plate is fixedly connected with a fixed cylinder. A positioning rod is arranged inside the fixed cylinder. One end of the positioning rod is fixedly connected with a square block. The square block is made of rubber. The square block and the clamping block are in contact with the housing. At this time, the flexible contact replaces the rigid extrusion to prevent the clamping marks, scratches or indentations from being left on the surface of the workpiece and meet the high surface quality requirements of the appearance parts. The positioning rod passes through the fixed cylinder, and a compression spring is sleeved on the outer side of the positioning rod. The two ends of the compression spring are respectively fixedly connected with the fixed cylinder and the square block. The number of the fixed cylinders is two, and the two fixed cylinders are symmetrically arranged at both ends of the arc plate.

[0013] Third Embodiment. On the basis of the first and second embodiments, please refer to the figures shown in the figures. The drilling assembly includes a threaded rod, both ends of the threaded rod are rotatably connected to both sides of the inner wall of the protective shell, the output end of the motor is fixedly connected to the threaded rod, a guide rod is fixedly connected inside the protective shell, the number of guide rods is two, and the two guide rods are symmetrically arranged with the threaded rod as the center. A guide block is threadedly connected to the outside of the threaded rod. The slider moves in the upper direction of the slide rail towards the drilling assembly, so that the fixing assembly drives the housing to move to a specified position. The motor is externally powered to work. The motor drives the threaded rod to rotate, and the threaded rod drives the guide block to move along the direction of the guide rod, so that the guide block drives the positioning block to move to the top of the housing. Subsequently, the positioning block slides down on the outside of the guide block, so that the drilling part at the bottom approaches the housing. At the same time, the DC motor is externally powered to work. The DC motor drives the connecting block to rotate, so that the connecting block drives the cylinder to rotate through the mutual engagement between the bottom block and the convex block. The cylinder drives the round block and the drill bit to rotate. The drill bit contacts and presses against the housing, and the L-shaped plate is compressed by the force. Utilizing the elastic performance of the L-shaped plate, the instantaneous impact force caused by uneven workpiece material or drill bit deviation during drilling can be absorbed, preventing the drill bit from damaging the workpiece due to excessive rigid feed pressure, avoiding hole depth out-of-tolerance, hole wall tearing or drill bit breakage. Thus, the drill bit drills the housing. The guide block is slidably connected to the guide rod, and a positioning block is slidably connected to the outside of the guide block. The positioning block is perpendicular to the guide block. A DC motor is fixedly connected to the top of the positioning block, and a drilling part is fixedly connected to the bottom of the positioning block. The output end of the DC motor penetrates the positioning block and is fixedly connected to the drilling part.

[0014] The drilling part includes a connecting block, the connecting block is fixedly connected to the bottom of the positioning block, an elastic plate is fixedly connected to the outside of the end of the connecting block away from the positioning block, a cylinder is fixedly connected to the end of the elastic plate away from the connecting block, a round block is slidably connected to the inside of the cylinder, a drill bit is fixedly connected to the middle of the bottom of the round block, a square groove is formed in the axial outer side of the round block, a limiting block is arranged on the inner wall of the cylinder near the square groove, and the limiting block is located inside the square groove. The DC motor is externally powered to work. The DC motor drives the connecting block to rotate, so that the connecting block drives the drill bit at the bottom to rotate. When the drill bit gets stuck, the block at the bottom of the connecting block and the convex block on the top of the circular plate are squeezed, so that the elastic plate is stretched by the force. Thus, the convex block is driven by the squeezing force to drive the cylinder to move downward on the outside of the round block through the circular plate. At this time, the drill bit stops rotating. An L-shaped plate is fixedly connected to the inner wall of the cylinder near the round block. The number of L-shaped plates is multiple, and the multiple L-shaped plates are evenly distributed inside the cylinder. The end of the L-shaped plate away from the cylinder is fixedly connected to the round block. A circular plate is fixedly connected to the inner wall of the cylinder, a convex block is fixedly connected to the side of the circular plate away from the round block, the number of convex blocks is multiple, a block is fixedly connected to the bottom edge of the connecting block near the cylinder, the number of blocks is multiple, and the multiple blocks and convex blocks are arranged alternately.

[0015] The present invention provides a shell drilling device for the production and processing of electronic devices. It has the following beneficial effects:

[0016] First, in the shell drilling device for the production and processing of electronic devices, by setting an L-shaped contact plate, the vertical and horizontal planes of the contact plate restrict multiple degrees of freedom of the shell to fix the shell, thereby ensuring the positional accuracy of the holes.

[0017] Second, in the shell drilling device for the production and processing of electronic devices, by setting an internal contact plate and an external clamping block, the internal clamping component fits with the inner wall of the shell to form a stable internal positioning reference to determine the internal position of the shell. The external clamping device applies pressure from the outside and cooperates with the internal clamping force to further fix the position of the shell in space, restricting the movement and rotation of its various degrees of freedom, achieving the full-range positioning of the shell, ensuring that the position of the shell is unique and fixed during drilling, and meeting the processing requirements of high-precision hole positions.

[0018] Third, in the shell drilling device for the production and processing of electronic devices, by setting a return spring and a compression spring, when the workpiece expands and contracts due to temperature changes or the shape slightly changes due to material removal during the processing, the clamping force can be automatically adjusted to avoid the loosening of the workpiece caused by the increased gap in traditional rigid clamping. Moreover, during the drilling process, the return spring and the compression spring can attenuate the transmission of the equipment vibration to the workpiece, reducing the machining accuracy deviation caused by vibration.

[0019] Fourth, in the shell drilling device for the production and processing of electronic devices, by utilizing the elastic properties of the L-shaped plate, the instantaneous impact force caused by uneven workpiece material or drill bit deviation during the drilling process can be absorbed, preventing the drill bit from being damaged by excessive rigid feeding pressure on the workpiece, avoiding over-depth holes, torn hole walls or drill bit breakage.

Inside the through groove 322, a screw 323 is rotatably connected. The housing to be processed is inverted on the top plate 327 on the top of the circular plate 321, so that the bottom of the inner wall of the housing contacts the top of the top plate 327. Subsequently, the driving motor 324 is powered on to work, so that the driving motor 324 drives the screw 323 to rotate. Thus, the screw 323 drives the fixing block 325 to move inside the through groove 322 towards the inner wall of the housing. Furthermore, the outer sides of the sides of the contact plate 326 respectively contact the side and the bottom edge of the inner wall of the housing. By setting the L-shaped contact plate 326, the vertical and horizontal planes of the contact plate 326 restrict multiple degrees of freedom of the housing to fix the housing, so as to ensure the position accuracy of the hole. Moreover, the contact area is larger and the clamping force is more evenly distributed, which can effectively prevent the deformation of the housing caused by local stress concentration during drilling.

Furthermore, the moving block 371 drives the connecting plate 372 and the arc plate 373 to move. By utilizing the elastic properties of the compression spring 379 and the return spring 3711, the clamping block 375 and the square block 378 are in close contact with the outside of the housing. By arranging the internal contact plate 326 and the external clamping block 375, the internal clamping component fits with the inner wall of the housing to form a stable internal positioning reference to determine the internal position of the housing.

A return spring 3711 is sleeved on the outer side of the sliding rod 374. By providing the return spring 3711 and the compression spring 379, when the workpiece expands or contracts due to temperature changes or the shape slightly changes due to material removal during the processing, the clamping force can be automatically adjusted, avoiding the loosening of the workpiece caused by the increased gap in traditional rigid clamping.

The slider 39 moves in the upper direction of the slide rail 2 towards the drilling assembly 7, so that the fixing assembly 3 drives the housing to move to the designated position. The motor 8 is powered by an external power supply. When the motor 8 works, it drives the threaded rod 72 to rotate. The threaded rod 72 drives the guide block 73 to move along the direction of the guide rod 71, so that the guide block 73 drives the positioning block 74 to move to the top of the housing. Subsequently, the positioning block 74 slides downward on the outside of the guide block 73, so that the drilling part 76 at the bottom approaches the housing. At the same time, the DC motor 75 is powered by an external power supply. When the DC motor 75 works, it drives the connecting block 761 to rotate, so that the connecting block 761 drives the cylinder 763 to rotate through the mutual engagement between the bottom block 7610 and the convex block 769. The cylinder 763 drives the round block 764 and the drill bit 765 to rotate. The drill bit 765 contacts and presses against the housing, and the L-shaped plate 767 is compressed under force. By using the elastic performance of the L-shaped plate 767, the instantaneous impact force caused by uneven workpiece material or drill bit deviation during drilling can be absorbed, preventing the drill bit from damaging the workpiece due to excessive rigid feed pressure, avoiding hole depth over-tolerance, hole wall tearing or drill bit breakage. Thus, the drill bit 765 drills the housing. The guide block 73 is slidably connected to the guide rod 71. A positioning block 74 is slidably connected to the outside of the guide block 73. The positioning block 74 is perpendicular to the guide block 73. A DC motor 75 is fixedly connected to the top of the positioning block 74. A drilling part 76 is fixedly connected to the bottom of the positioning block 74. The output end of the DC motor 75 penetrates through the positioning block 74 and is fixedly connected to the drilling part 76.

[0043] The drilling component 76 includes a connecting block 761. The connecting block 761 is fixedly connected to the bottom of the positioning block 74. An elastic plate 762 is fixedly connected to the outer side of one end of the connecting block 761 away from the positioning block 74. A cylinder 763 is fixedly connected to one end of the elastic plate 762 away from the connecting block 761. A round block 764 is slidably connected inside the cylinder 763. A drill bit 765 is fixedly connected to the middle of the bottom of the round block 764. A square groove 766 is formed in the axial outer side of the round block 764. A limiting block is provided on the inner wall of the cylinder 763 close to the square groove 766, and the limiting block is located inside the square groove 766. The DC motor 75 operates with an external power supply. The operation of the DC motor 75 drives the connecting block 761 to rotate, so that the connecting block 761 drives the drill bit 765 at the bottom to rotate. When the drill bit 765 gets stuck, the block 7610 at the bottom of the connecting block 761 is squeezed between the convex block 769 at the top of the circular plate 768, causing the elastic plate 762 to be stretched under force. Thus, the convex block 769 drives the cylinder 763 to move downward on the outer side of the round block 764 through the circular plate 768 under the squeezing force. At this time, the drill bit 765 stops rotating. An L-shaped plate 767 is fixedly connected to the inner wall of the cylinder 763 close to the round block 764. The number of L-shaped plates 767 is multiple, and the multiple L-shaped plates 767 are evenly distributed inside the cylinder 763. One end of the L-shaped plate 767 away from the cylinder 763 is fixedly connected to the round block 764. A circular plate 768 is fixedly connected to the inner wall of the cylinder 763. A convex block 769 is fixedly connected to one side of the circular plate 768 away from the round block 764. The number of convex blocks 769 is multiple. A block 7610 is fixedly connected to the bottom edge of the connecting block 761 close to the cylinder 763. The number of blocks 7610 is multiple, and the multiple blocks 7610 and convex blocks 769 are arranged alternately.

[0044] During use, the housing to be processed is inverted on the top plate 327 on the top of the circular plate 321, so that the bottom of the inner wall of the housing contacts the top of the top plate 327. Subsequently, the driving motor 324 operates with an external power supply, so that the driving motor 324 drives the screw 323 to rotate. Thus, the screw 323 drives the fixed block 325 to move inside the through groove 322 towards the inner wall of the housing, and further makes the outer sides of the sides of the contact plate 326 contact the side and the bottom edge of the inner wall of the housing respectively.

[0045] The housing is inverted on top of the top plate 327. At this time, the side of the housing is sleeved outside the top plate 327. The driving motor 324 operates to drive the screw rod 323 to rotate, so that the screw rod 323 drives the contact plate 326 through the fixing block 325 to support and fix the inside of the housing. After being fixed, the motor 38 is externally powered to operate. The motor 38 operates to drive the gear 310 to rotate, so that the gear 310 drives the ring 33 through the tooth block 36. The ring 33 drives the inner arc block 35 to rotate, so that the arc block 35 contacts and squeezes the moving block 371, thereby causing the moving block 371 to move along the fixed rod 3211 inside the square hole 3210 towards the direction of the top plate 327. Furthermore, the moving block 371 drives the connecting plate 372 and the arc plate 373 to move. By utilizing the elastic properties of the compression spring 379 and the return spring 3711, the clamping block 375 and the square block 378 are in close contact with the outside of the housing. By arranging the internal contact plate 326 and the external clamping block 375, the internal clamping component fits with the inner wall of the housing to form a stable internal positioning reference to determine the internal position of the housing. The external clamping device applies pressure from the outside and cooperates with the internal clamping force to further fix the position of the housing in space, restricting the movement and rotation of its various degrees of freedom, realizing the all-round positioning of the housing, and ensuring that the position of the housing is unique and fixed during drilling.

[0046] The motor 8 is externally powered to operate. The motor 8 operates to drive the threaded rod 72 to rotate. The threaded rod 72 drives the guide block 73 to move along the direction of the guide rod 71, so that the guide block 73 drives the positioning block 74 to move to the top of the housing. Subsequently, the positioning block 74 slides down outside the guide block 73, so that the drilling component 76 at the bottom approaches the housing. At the same time, the DC motor 75 is externally powered to operate. The DC motor 75 operates to drive the connecting block 761 to rotate, so that the connecting block 761 drives the cylinder 763 to rotate through the mutual engagement between the bottom block 7610 and the convex block 769. The cylinder 763 drives the round block 764 and the drill bit 765 to rotate, thereby drilling the housing with the drill bit 765.
