Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of lock accessory processing equipment, and particularly relates to a multi-station automatic equipment for lever handle processing and assembly. BACKGROUND

[0002] In the lock industry, the lever handle (also known as the lever handle) is an important accessory of the door lock, mainly used for controlling the opening and closing of the lock tongue, and simultaneously serving as the operating part of the door handle. During the production and processing of the lever handle, after the rough blank is completed, it needs to be punched by a punching equipment to remove the burrs on the rough blank, then threaded holes are tapped in the corresponding holes by a tapping equipment, and finally the generation of the lever handle is completed by automatically screwing the screws into the holes through an automatic screwing equipment;

[0003] This existing lever handle production process requires multiple devices to process the lever handle rough blank, and the lever handle needs to be transported multiple times during the production process, which greatly reduces the work efficiency and occupies a large space area in the generation workshop, thus it is necessary to make improvements. SUMMARY

[0065] Overall structure and layout of the device

[0066] The handle head processing assembly in the embodiment adopts high-strength steel material welding to form a rectangular frame structure, and a shock-absorbing caster wheel can be installed at the bottom to facilitate the movement and positioning of the equipment. The disc-shaped workbench 8 is rotatably installed at the top central position of the main body 7 through a high-precision annular slide rail, which can provide stable support and smooth rotation performance. The stepping motor selects a stepping motor with a model number of 57BYGH250B. The motor has high torque and precision, and can meet the frequent stepping rotation requirements of the disc-shaped workbench 8. The stepping motor is arranged at the bottom of the main body 7, and is connected to the center of the bottom of the disc-shaped workbench 8 through a synchronous belt transmission mechanism to drive the disc-shaped workbench 8.

[0067] Six material tables 9 are evenly distributed at the edges of the disc-shaped workbench 8. The material tables 9 are made of aluminum alloy material and have good wear resistance and corrosion resistance after anodizing treatment. Each material table 9 has a handle head placing groove 90 on the surface, which is matched with the shape of the handle head rough blank. The size accuracy of the placing groove is controlled within ±0.1 mm to ensure that the handle head rough blank can be accurately placed and will not shake.

[0068] The positions of the stamping mechanism 1, the upper bolt mechanism 3, the feeding and discharging mechanism, the scrap blowing mechanism and the tapping mechanism 2 correspond to one material table 9. The disc-shaped workbench 8 switches the positions of several material tables 9 by rotating to move the position of the previous material table 9 to the position of the next material table 9, thereby switching the work station.

[0069] The disc-shaped workbench 8 is rotatably installed on the main body 7 in a conventional manner, such as through a bearing or an annular slide rail. The stepping motor is arranged in the main body 7 and is drivingly connected to the center of the bottom of the disc-shaped workbench 8.

[0070] The stamping mechanism 1, the upper bolt mechanism 3, the feeding and discharging mechanism, and the vibration feeding mechanism 6 are all prior art. Specifically, the impact mechanism can include a stamping head matched with the shape of the handle head, which can remove burrs on the handle head rough blank during the pressing process. The stamping head is driven by a hydraulic cylinder driving system, and a guide column and a linear bearing are used to ensure the vertical stability of the stamping process. Preferably, a pressure sensor can be further arranged to monitor the stamping force in real time to prevent overload.

[0071] The upper bolt mechanism 3 can include a bolt vibration disc and a straight vibration track for directional conveying of bolts, as well as a pneumatic or electric screwdriver with a magnetic head capable of attracting bolts. Through a three-axis mechanical arm (XYZ linear module), it can be precisely positioned to the screw hole of the handle head. It can also include a conventional pressure feedback system and a visual detection camera.

[0072] The upper feeding manipulator 4 and the lower feeding manipulator 5 include a conventional six-axis articulated robot or a SCARA manipulator or a two-axis manipulator (horizontal and vertical linear modules), the end effector is a pneumatic gripper, the positioning system is a machine vision positioning (CCD camera + light source), and the driving is realized through a servo motor;

[0073] The vibration feeding mechanism 6 includes a conventional vibration disc, a spiral track and a directional arrangement mechanism, and is used for screening the posture of the handle head rough blank.

[0074] The waste blowing mechanism is arranged on the main body 7, and the waste blowing mechanism includes a compressed air source and an adjustable air outlet pipe.

[0075] The stamping mechanism 1, the tapping mechanism 2 and the upper bolt mechanism 3 in the processing mechanism, and the upper feeding manipulator 4 and the lower feeding manipulator 5 in the feeding mechanism are uniformly and spacedly distributed on the main body 7 along the circumference of the disc-shaped workbench 8. The vibration feeding mechanism 6 is arranged on the left side of the main body 7, the vibration disc thereof is a vibration disc with a model number of ZDP-100, the spiral track and the directional arrangement mechanism are customized and designed according to the shape and size of the handle head rough blank, and the handle head rough blank can be stably and efficiently conveyed to the upper feeding manipulator 4. The waste blowing mechanism is arranged on the rear side of the main body 7, the compressed air source is an air compressor with a model number of V-1.0 / 7, the air outlet pipe is a bendable PVC air pipe, and the angle and position of the air pipe can be adjusted to blow the waste generated by tapping the handle head.

[0076] The stamping mechanism

[0077] The stamping head of the stamping mechanism 1 is made of 45 steel and is subjected to quenching and grinding processing, the outer shape thereof is accurately matched with the outer shape of the handle head rough blank, and it can ensure that burrs are accurately punched off in the stamping process. The hydraulic cylinder driving system selects a hydraulic cylinder with a model number of HOB63x100, the hydraulic cylinder has sufficient thrust and stroke, and can meet the needs of stamping operation. The guide column is a cylindrical light shaft with a diameter of 20 mm, and the linear bearing selects a linear bearing with a model number of LM20UU, the guide column is used in cooperation with the linear bearing, the vertical accuracy of the stamping head in the up-down movement process can be ensured, and the vertical error is controlled to be within ±0.05 mm. The pressure sensor selects a high-precision pressure sensor with a model number of HBM U10M, is installed at the end of the piston rod of the hydraulic cylinder, can monitor the stamping force in real time, and transmits the pressure signal to the control system of the equipment. When the stamping force exceeds the set threshold value, the control system will immediately issue an alarm and stop the stamping operation to prevent overload damage.

[0078] The tapping mechanism

[0079] The lifting driving part 20 of the tapping mechanism 2 adopts a type JIF-63x50 air cylinder, which is fixedly installed on the main body 7 through a support frame. The piston rod end of the air cylinder is connected with the shell 210 of the tapping head driving part 21, and the shell 210 can be driven to move up and down. The shell 210 of the tapping head driving part 21 is made of aluminum alloy, and a driving motor 211 of type 5IK120GN-C is installed inside. The driving motor 211 is in transmission connection with the clamping body 212 through a set of bevel gears, which includes a driving bevel gear arranged at the driving end of the driving motor 211, a driven bevel gear arranged at the top end of the clamping body 212, and two intermediate bevel gears arranged between the driving bevel gear and the driven bevel gear, which are connected with the shell 210 through a gear shaft. The clamping body 212 is made of high-strength stainless steel, and the clamp is a conventional mechanical fixed clamp. The clamp body is in a cylindrical structure, and a hole matched with the connecting end of the tapping head body 22 is arranged inside. On the outside of the clamp, there are adjusting bolt holes, and an adjusting bolt is installed in each hole. Two heat-conducting copper pipes 214 are arranged on the clamping surface of the clamp. One end of the heat-conducting copper pipe 214 extends into the heat-conducting medium cavity 213 inside the clamping body 212. The heat-conducting medium cavity 213 is filled with heat-conducting medium, which can be heat-conducting oil, deionized water, glycol solution or liquid metal, and has good heat-conducting performance. The tapping head body 22 and the clamping surface can be coated with heat-conducting silicone grease. Preferably, the tapping head body 22 can be a conventional internal cooling cutter, that is, the tapping head body 22 also has heat-conducting copper pipes 214 arranged inside. Compared with the traditional dry cooling, the cooperation of the heat-conducting copper pipes 214 and the heat dissipation part 23 can effectively improve the heat dissipation effect of the tapping head body 22 and avoid chemical pollution caused by cutting fluid.

[0080] The shell 230 of the heat dissipation part 23 is made of aluminum alloy, and a set of heat dissipation fins 231 is arranged inside. The heat dissipation fins 231 have a large surface area, which can effectively increase the heat dissipation area. One air blowing part 232 is installed on each side of the shell 230. The air blowing part 232 can provide strong air flow, and the air blowing part 232 includes a conventional fan driven by a motor. The heat-conducting pipe 233 is made of red copper pipe, one end of which is inserted into the heat-conducting medium cavity 213, and the other end extends through the top space of the clamping body 212 to the shell 230 and passes through the heat dissipation fin set 231. The design of the bevel gear transmission facilitates the arrangement of the heat-conducting pipe 233.

[0081] The fan support frame 12 is made of metal and arranged in the annular fan frame 16 to support the fan shaft 100. A plurality of wind blocking boxes 13 are uniformly and spacedly arranged on the outer wall of the annular fan frame 16 along the circumferential direction of the annular fan frame 16. The air guide pipe 14 is made of PVC and arranged on the shell 230. Two air guide pipes 14 are arranged corresponding to the air blowing member 232. The air inlet end of the air guide pipe 14 is located at the air outlet side of the air blowing member 232. The air outlet end extends to the side of the annular fan frame 16 and is tangent to the radial direction of the annular fan frame 16. The air guide pipe 14 can accurately blow the air flow generated by the air blowing member 232 to the wind blocking box 13 to drive the driven fan 10 to rotate. The driven fan 10 does not need to be additionally configured with an independent driving motor 211 and a complex transmission device. The driven fan 10 directly converts the wind energy generated by the air blowing member 232 into the kinetic energy of its own rotation. During the operation of the hand processing and assembly equipment, the air blowing member 232 originally needs to work to accelerate the air flow between the heat dissipation fin groups 231. The driven fan 10 ingeniously utilizes the part of the surplus wind energy to realize the operation of “zero additional energy consumption”. Compared with the traditional independent driving fan, the driven fan 10 can save a large amount of electric energy and reduce the overall operation cost of the equipment.

[0082] The driven fan 10 is rotatably installed inside the bottom side of the shell 230 through the annular fan frame 16 made of plastic material, which has the characteristics of light weight and high strength. The driven fan 10 includes a fan shaft 100 and a plurality of fan blades 101, and the fan shaft 100 is provided with a plurality of torsion grooves 102 corresponding to the fan blades 101, which extend from the inside to the outside along the radial direction of the fan shaft 100. The root of the fan blade 101 cooperates with the torsion groove 102 to form a twisted shape, and the root of the fan blade 101 is movably arranged in the torsion groove 102 and can move along the length direction of the torsion groove 102. The inner side of the torsion groove 102 is further provided with a cylindrical groove 103, and a limiting block 104 is movably arranged in the cylindrical groove 103. The limiting block 104 is connected with the root of the fan blade 101 through a connecting shaft, and a spring 105 is also installed in the cylindrical groove 103 (the spring 105 is sleeved on the connecting shaft, and one end of the spring 105 is connected with the limiting block 104, and the other end is connected with the end face of the cylindrical groove 103). The diameter size of the cylindrical groove 103 is greater than the thickness of the torsion groove 102. When the rotating speed of the fan shaft 100 is low, the spring 105 pulls the fan blade 101 inward, and the windward area of the fan blade 101 is small, so that the air resistance of the driven fan 10 is greatly reduced when starting. The smaller windward area allows the driven fan 10 to start rotating more easily under the action of weak air flow, avoiding the situation that the fan cannot respond in time and starting difficulty due to too large starting resistance, so as to ensure that the heat dissipation system can quickly enter the working state at the beginning of the equipment operation, and provide timely heat dissipation protection for the tapping head main body 22. With the operation of the equipment, the air flow generated by the air blowing part 232 gradually increases, and the rotating speed of the fan shaft 100 also increases. Under the action of centrifugal force, the fan blade 101 moves outward along the torsion groove 102. Due to the special matching structure of the root of the fan blade 101 and the torsion groove 102, the fan blade 101 is twisted around the connecting shaft during the outward movement, so that the windward area of the fan blade 101 gradually increases. This process realizes the self-adaptive adjustment of the ventilation quantity. When a large amount of heat is generated during the tapping operation, and stronger heat dissipation capacity is required, the increased windward area allows the driven fan 10 to suck in more external air, accelerate the flow of air between the heat dissipation fin groups 231, and thus carry away more heat.

[0083] The filter pipe 150 of the filter 15 is made of plastic material, covers the air inlet side of the corresponding air blowing part 232 and the air inlet 11, and is provided with a filter layer 151 composed of activated carbon and fiber filter screen inside, which can effectively filter the external air entering the inside of the shell 230. The cleaning roller 152 is made of rubber material, and is provided with bristles on the surface. The cleaning roller 152 is arranged in the filter pipe 150 and located at the front side of the filter surface of the filter layer 151. The roller driving unit 153 includes two sliding blocks 1530, a lead screw transmission structure 1531, a support arm 1532, a linear driving device 1533 and a cleaning roller driving motor 1534. The two sliding blocks 1530 are respectively slidably installed on the two first guide rails 1535 on the inner wall of the cavity. One of the sliding blocks 1530 is driven by the lead screw transmission structure 1531 to actively move back and forth along the first guide rail 1535. The two sliding blocks 1530 are slidably installed with the support arm 1532 perpendicular to the first guide rail 1535. The end of the cleaning roller 152 is rotatably connected with the support arm 1532. The second guide rail 1536 is also arranged on the inner wall of the cavity, and the sliding table is slidably installed on the second guide rail 1536. The linear driving device 1533 is fixedly installed on the sliding table, and the driving end of the linear driving device 1533 is connected with the support arm 1532 for driving the support arm 1532 to move. The support arm 1532 is installed with the cleaning roller driving motor 1534, which is in transmission connection with the end of the cleaning roller 152 for driving the cleaning roller 152 to rotate. The lead screw transmission structure 1531 is composed of a servo motor (which can be linked with the equipment control system), a lead screw and a nut. Specifically, taking the air blowing part 232 as an example, during the one-way repeated cleaning process of the cleaning roller 152, the servo motor rotates to drive the lead screw to rotate, and the nut moves linearly on the lead screw to drive the sliding block 1530 connected therewith to move back and forth on the first guide rail 1535. Initially, the cleaning roller 152 is in contact with the filter surface of the filter layer 151, the cleaning roller driving motor 1534 drives the cleaning roller 152 to rotate to clean the filter surface of the filter layer 151, and at the same time, the cleaning roller 152 moves downward. When the cleaning roller 152 moves to the lowest end, the linear driving device 1533 drives the support wall to move, thereby separating the cleaning roller 152 from the filter surface of the filter layer 151, and at the same time, the cleaning roller 152 moves upward for resetting under the driving of the lead screw transmission structure 1531, so that the cleaning roller 152 is reset in the separated state from the filter surface, thereby cleaning the filter surface of the filter pool repeatedly, thereby effectively avoiding the secondary pollution of the cleaning roller 152 when cleaning the filter layer 151.

[0084] The arrangement of the filter 15 can effectively prevent the phenomenon that the heat dissipation fin group 231 is attached with dust to reduce the heat dissipation effect, ensure the heat dissipation effect of the tapping head main body 22, and the cleaning roller 152 can further keep the filter layer 151 clean to ensure the ventilation effect.

[0085] Upper bolt mechanism

[0086] The bolt vibration plate of the upper bolt mechanism 3 can be a vibration plate of model ZDP-80, and the straight vibration track is made of stainless steel, which can stably direct the bolt to the designated position. The pneumatic screwdriver with a magnetic head can be a pneumatic screwdriver of model WR-8100, which is accurately positioned to the handle head screw hole through a three-axis mechanical arm (composed of an XYZ linear module of model THK KR20). The pressure feedback system adopts a pressure sensor of model HBM U2B, which can monitor the pressure in the bolt installation process in real time to ensure that the bolt installation force is appropriate.
