Description

Technical Field

[0001] The invention belongs to the technical field of carbon fiber shell punching, in particular to a punching device for producing a carbon fiber electronic shell. Background Art

[0002] Carbon fiber electronic shell is an electronic product shell made of carbon fiber material, which has the characteristics of high strength, light weight, high hardness, good heat dissipation and fashion simplicity. Carbon fiber is well known for its high strength and light weight, which makes it an ideal material for manufacturing electronic product shells. Carbon fiber electronic shells can effectively resist external impact and wear, and provide comprehensive protection for internal electronic components. At the same time, due to the low density of carbon fiber, the overall weight of electronic products can be significantly reduced, making them easy to carry and use. In addition, the hardness of carbon fiber electronic shells is very high, which can resist daily scratches and collisions, making electronic products safer during use. Its stylish and simple appearance design and high-grade texture also add a lot of charm to electronic products. Carbon fiber materials also have excellent heat dissipation performance, which can quickly dissipate the heat generated by electronic products and maintain the stable operation of the products. In the process of drilling holes in carbon fiber electronic housings in the prior art, since the carbon fiber layer has no binding force, it will be subjected to the axial force pushed outward by the drill bit, resulting in uncut fiber edges on the housing, forming burrs. In addition, due to the poor thermal conductivity of carbon fiber composite materials, the heat generated during the drilling process cannot be released quickly, resulting in a high temperature in the hole making area. After drilling is completed, shrinkage will occur, affecting the hole size accuracy. Summary of the invention

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0018] like Figures 1 to 9As shown, the present invention provides a punching device for producing a carbon fiber electronic housing, comprising a working machine 1, a T-shaped plate groove 11 is provided on a plate body on one side of the working machine 1, and a carbon fiber electronic housing body 12 can be fitted and connected in the top inner wall of the T-shaped plate groove 11, a table frame 13 is provided on one side of the working machine 1, and an electric cylinder 14 and an elastic telescopic rod 15 are respectively fixedly connected to the plate body at one end of the table frame 13, and the electric cylinder 14 and the elastic telescopic rod 15 are fixedly connected through a connecting rod, and a rubber pad 16 is fixedly connected to the bottom end of the elastic telescopic rod 15, and the bottom end of the rubber pad 16 can be intermittently fitted and connected with the top side wall of the carbon fiber electronic housing body 12, and a drill rod 17 is provided directly below the electric cylinder 14, and the drill rod 17 and the carbon fiber electronic housing body 12 can be fitted and rotatably connected, and a punching protection part 2 is provided between the electric cylinder 14 and the drill rod 17; The drilling protection part 2 includes a motor 21 fixedly connected to the outer wall of the bottom end of the electric cylinder 14 and capable of forward and reverse rotation. A pipe rod 22 is fixedly connected to the rotating shaft of the motor 21. The drill rod 17 is specifically composed of two parts, the upper half is a smooth rod, and the lower half is a threaded rod. A magnetic ring is fixedly connected to the top of the threaded rod. A ring groove that can be magnetically rotatably connected to the magnetic ring is provided in the bottom end of the smooth rod. The bottom end of the pipe rod 22 is fixedly connected to the top end of the threaded rod of the drill rod 17, and a rod groove for holding water is provided through the top end of the drill rod 17. A sleeve 23 is also movably sleeved on the rotating shaft of the motor 21, and a hopper pipe 24 for placing saltpeter is fixedly connected through one end of the sleeve 23 near the bottom. A spur gear 28 is movably sleeved on the rod body of the tube rod 22, and four arc grooves 29 are circumferentially opened on the spur gear 28. A slide rod 230 is slidably connected to the inner wall of each arc groove 29, and a grinding block 232 is fixedly connected to the bottom end of each slide rod 230. The outer wall of each grinding block 232 can be intermittently fitted and rotatably connected to the drilled hole on the carbon fiber electronic housing body 12.

[0019] The above scheme is adopted: by placing the carbon fiber electronic housing body 12 in the T-shaped plate groove 11 on the working machine 1, and then the workers uniformly turn on the electric cylinder 14 and the motor 21, so that the electric cylinder 14 will automatically drive the elastic telescopic rod 15 and the rubber pad 16 to move downward, at this time, the drill rod 17 will be indirectly driven downward by the electric cylinder 14, and indirectly driven to rotate by the motor 21, the rubber pad 16 will first move downward to contact the outer wall of the carbon fiber electronic housing body 12, and further fix it. Then, the drill rod 17 rotates downward to punch holes in the shell of the carbon fiber electronic housing body 12. When the drill rod 17 is rotated downward, the outer wall of the carbon fiber electronic housing body 12 is further fixed and limited. After the rod 17 moves down to drill through the carbon fiber electronic housing body 12, the grinding block 232 connected to the drill rod 17 is also located on the inner and outer walls of the hole, and the tooth plate 241 and the spur gear 28 are meshed. The subsequent passively rotating spur gear 28 will drive the slide bar 230 in real time under the limit of the rectangular groove plate 231, and guide and slide in the arc groove 29, thereby driving the grinding block 232 to separate from the outer wall of the drill rod 17 and instead fit with the inner wall of the hole drilled on the carbon fiber electronic housing body 12. As a result, the grinding block 232 is subsequently rotated to grind the inner wall of the hole and the outer walls at the upper and lower ends at the same time to solve the problem of burrs generated during drilling.

[0020] The punching protection part 2 specifically also includes a semi-arc plate 25 fixedly connected to the outer wall of one end of the pipe rod 22, and a material trough is specifically opened at the rod body where the pipe rod 22 is connected to the semi-arc plate 25. The bottom outer wall of the sleeve 23 and the top outer wall of the spur gear 28 are fitted and connected, and a Y-shaped rod is fixedly connected between the hopper tube 24, the smooth rod, and the elastic telescopic rod 15. A ball rod 26 can be intermittently clamped on the material trough. The spherical body at one end of the ball rod 26 is specifically made of natural rubber. A spring 27 is fixedly connected between the rod body of the ball rod 26 and the inner wall of one end of the sleeve 23. A rectangular groove plate 231 is also fitted and slidably connected to the rod body of each sliding rod 230, and a ring plate 233 is fixedly connected to the outer wall of one end of the plurality of rectangular groove plates 231. The inner wall of the ring plate 233 and the outer wall of the drill rod 17 near the top are fitted and connected.

[0021] The above scheme is adopted: the operation of the motor 21 will first drive the pipe rod 22 connected to the top of the drill rod 17 to rotate, and the rotating pipe rod 22 will drive the semi-arc plate 25 to rotate in real time, and then repeatedly squeeze the ball rod 26, so that it is forced to squeeze the spring 27. The existence of the spring 27 will cause the ball rod 26 to retract under force, and automatically reset by elastic force in the absence of external force. The intermittent extension and contraction of the ball rod 26 can make the saltpeter particles falling in the hopper tube 24 be discharged from the material trough through the rotation of the semi-arc plate 25, directly It falls into the rod groove of the drill rod 17, thereby mixing with the water introduced in advance in the rod groove, absorbing the heat of the water, cooling it quickly, and transmitting the low temperature to the drill rod 17, avoiding the drilling process between the drill rod 17 and the carbon fiber electronic housing body 12. The heat generated by the friction of drilling cannot be dissipated quickly, and the higher the friction, the higher the heat, causing shrinkage at the hole mouth. When the drill rod 17 moves down to drill through the carbon fiber electronic housing body 12, the grinding block 232 connected to the drill rod 17 is also located on the inner and outer walls of the hole mouth.

[0022] Block grooves are provided on the inner walls at both ends of the ring plate 233 and the outer walls at both ends of the drill rod 17 near the top. Springs 235 are fixedly connected to the inner walls of the block grooves at both ends of the ring plate 233. The other ends of the two springs 235 are fixedly connected to blocks 234. The two blocks 234 can be intermittently and tightly engaged with the inner walls of the block grooves at both ends of the drill rod 17. A pressure plate 236 is fixedly connected to the outer wall of the other end of the sleeve 23 near the bottom, and a sensor 237 can be intermittently fitted on the outer wall of the bottom end of the pressure plate 236.

[0023] The above scheme is adopted: the grinding block 232 connected to the drill rod 17 is located at the inner and outer walls of the hole, the tooth plate 241 and the spur gear 28 are meshed, and at the same time, the pressure plate 236 on the outer wall of the sleeve 23 contacts and presses the sensor 237, and the rotating spur gear 28 will drive the slide bar 230 in real time under the limit of the rectangular groove plate 231, and guide and slide in the arc groove 29, thereby driving the grinding block 232 to separate from the outer wall of the drill rod 17, and instead fit with the inner wall of the hole drilled on the carbon fiber electronic housing body 12, and in the straight When the gear 28 is in a continuous passive rotation state, the force passively borne by the ring plate 233 will increase, thereby driving the block 234 to disengage from the block groove on the pipe rod 22, and synchronously squeezing the spring 235 on the block 234 to deform it and slide on the outer wall of the pipe rod 22. The sliding process will cause the sliding rod 230, the rectangular groove plate 231, the grinding block 232, and the ring plate 233 to rotate synchronously, thereby causing the grinding block 232 to rotate and grind the inner wall of the hole and the outer walls at the upper and lower ends at the same time, thereby solving the problem of burrs generated during drilling.

[0024] A slide plate is fixedly connected to the bottom end of the sensor 237, a forward and reverse rotating motor 238 is fixedly connected to the side wall of one end of the table frame 13, a screw 239 is fixedly connected to the rotating shaft of the motor 238, the screw 239 is threadedly connected to the plate body on one side of the slide plate, a guide rod 240 is also slidably connected to the plate body on the other side of the slide plate, a tooth plate 241 is fixedly connected to the outer wall of one end of the slide plate, and the tooth plate 241 and the spur gear 28 can be intermittently meshed.

[0025] The above scheme is adopted: the pressure plate 236 on the outer wall of the sleeve 23 contacts and presses the sensor 237, so that its transmission motor 238 drives the screw 239 to rotate, thereby driving the slide plate and the tooth plate 241 to move horizontally under the limit of the guide rod 240, so that the passively horizontally moving tooth plate 241 will drive the meshing spur gear 28 to rotate.

[0026] One point that needs to be added is that the sensor 237 mainly plays the role of detection and feedback in the automation system. It can sense certain physical quantities in the environment, such as light, temperature, position, etc., and convert such physical quantities into electrical signals or other recognizable forms. These signals are then transmitted to the controller. After receiving these signals, the controller will determine how to control the motor 238 according to the preset program or algorithm. For example, if the sensor 237 detects that the object has reached a certain position, the controller can issue a command to let the motor 238 operate. The control of the motor 238 is realized through the "intermediary" of the controller. The reciprocating operation of the pressure plate 236 indirectly conveys the operation process of the forward and reverse rotation to the sensor 237. The passive rotation of the drill rod 17 specifically refers to the rotation of the threaded rod, and the connection means between the threaded rod and the smooth rod and the condition that the smooth rod is limited will only cause the threaded rod to rotate passively, which is convenient for the subsequent separation of the hollow threaded rod from the smooth rod, so as to clean the mixed substance between the saltpeter and the water in the screw rod, and also convenient for the immediate replacement or maintenance of the threaded rod after long-term use.

[0027] The working principle and use process of the present invention are as follows: by placing the carbon fiber electronic housing body 12 in the T-shaped plate groove 11 on the working machine 1, and then the workers uniformly turn on the electric cylinder 14 and the motor 21, so that the electric cylinder 14 will automatically drive the elastic telescopic rod 15 and the rubber pad 16 to move downward, at this time, the drill rod 17 will be indirectly driven downward by the electric cylinder 14, and indirectly driven to rotate by the motor 21, the rubber pad 16 will first move downward to contact the outer wall of the carbon fiber electronic housing body 12, and further fix it. Then, the drill rod 17 rotates and moves downward to punch the shell of the carbon fiber electronic housing body 12. As the drill rod 17 gradually rotates and moves downward, the rod body of the elastic telescopic rod 15 will also retract in real time. The operation of the motor 21 will specifically drive the top of the drill rod 17 to rotate. The connected pipe rod 22 rotates, and the rotating pipe rod 22 will drive the semi-arc plate 25 to rotate in real time, and then repeatedly squeeze the ball rod 26, so that it is forced to squeeze the spring 1 27. The existence of the spring 1 27 will cause the ball rod 26 to retract under force, and automatically reset by elastic force without external force. The intermittent expansion and contraction of the ball rod 26 can make the saltpeter particles falling in the hopper tube 24 be discharged from the material trough through the rotation of the semi-arc plate 25, and directly fall into the rod groove of the drill rod 17, so as to mix with the water body introduced in advance in the rod groove, so as to absorb the heat of the water body, make it cool quickly, and transmit the low temperature to the drill rod 17, so as to avoid the drilling process between the drill rod 17 and the carbon fiber electronic housing body 12. The heat generated by the drilling friction cannot be quickly dissipated, and the higher the friction heat, the shrinkage hole will be generated at the hole mouth; When the drill rod 17 moves down to drill through the carbon fiber electronic housing body 12, the grinding block 232 connected to the drill rod 17 is also located on the inner and outer walls of the hole, and the tooth plate 241 and the spur gear 28 are meshed. At the same time, the pressure plate 236 on the outer wall of the sleeve 23 contacts and presses the sensor 237, so that its transmission motor 238 drives the screw 239 to rotate, thereby driving the slide plate and the tooth plate 241 to move horizontally under the limit of the guide rod 240, so that the passively horizontally moving tooth plate 241 will drive the meshing spur gear 28 to rotate, and the rotating spur gear 28 will drive the slide bar 230 to slide in the arc groove 29 under the limit of the rectangular groove plate 231 in real time, thereby The grinding block 232 is driven to separate from the outer wall of the drill rod 17 and to fit with the inner wall of the hole drilled on the carbon fiber electronic housing body 12. When the spur gear 28 is in a continuous passive rotation state, the passive force on the ring plate 233 is increased, thereby driving the clamping block 234 to separate from the block groove on the pipe rod 22, and synchronously squeezing the spring 235 on the clamping block 234 to deform it and fit and slide on the outer wall of the pipe rod 22. The sliding process will cause the sliding rod 230, the rectangular groove plate 231, the grinding block 232, and the ring plate 233 to rotate synchronously, thereby causing the grinding block 232 to rotate and grind the inner wall of the hole and the outer walls at the upper and lower ends at the same time, thereby solving the problem of burrs generated during drilling.
