Description

Technical Field

[0001] The invention relates to the technical field of shaft processing equipment, in particular to a shaft drilling and grooving equipment. Background Art

[0002] The slotting and drilling process of shaft products requires the use of production equipment with slotting and drilling functions. The production equipment will drill and slot the ends of the shaft products under the control of CNC programming and PLC systems.

[0003] At present, in the prior art, in a Chinese patent document with the authorization announcement number CN209062540U, a screw cross groove cutting and drilling device is recorded, including a workbench, a vibration plate, a first guide rail, a feeding device, a vertical groove cutting machine, a processing device and a clamping device. The nail blanks are placed in the vibration plate, sorted by the vibration plate, and the nail blanks are fed into the feeding device one by one through the first guide rail, and the nail blanks that slide down are blocked by the limit plate. The second actuator drives the top block to send the nail blank into the gripper cylinder, and one end of the nail blank is directly fitted with one side of the gripper cylinder. Then, the gripper cylinder clamps the nail blank, and the third actuator drives the lifting mechanism to drive the connecting plate to move downward to the same horizontal plane as the processing device and stops. The first actuator drives the drilling device and the cutting device to move toward the nail blank, drill holes in the nail blank and horizontally groove it. After the processing is completed, the processing device is reset. The third actuator continues to drive the gripper cylinder to move downward, and the vertical groove cutting device vertically grooves the nail blank. The gripper cylinder continues to move downward to the bottom, and the unloading device starts to work. The cylinder drives the push block to move toward the nail blank and pushes the nail blank away from the gripper cylinder.

[0004] The above-mentioned prior art solutions have the following defects: the unloading device on the drilling device only pushes the nail blank away from the gripper cylinder, and cannot transfer the unloaded workpiece to the next process station, which requires manual transportation between process stations, which is very troublesome and inefficient. Summary of the invention

[0005] In view of the deficiencies in the prior art, one of the purposes of the present invention is to provide a drilling and grooving device for shaft parts, which can more efficiently and automatically transfer the processed workpiece to the next process station.

[0006] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0007] A drilling and grooving device for shaft parts comprises a frame, the frame is provided with a loading mechanism, a clamping mechanism, a feeding mechanism for pushing the workpiece from the loading mechanism to the clamping mechanism, a hole punching device for drilling holes in the workpiece on the clamping mechanism and a groove punching device for slotting the workpiece on the clamping mechanism, the frame is provided with a unloading mechanism for pushing the processed workpiece out from one side of the clamping mechanism, the frame is provided with a gear mechanism, a material shifting member and a conveyor belt mechanism, the gear mechanism is rotatably arranged on the frame, the gear mechanism is provided with a unloading trough for receiving the workpiece pushed out from one side of the clamping mechanism, the material shifting member is located on one side of the gear mechanism and has an inclined surface, the material shifting member shifts the workpiece out of the unloading trough and sends the workpiece to the conveyor belt mechanism through the inclined surface, and the conveyor belt mechanism transports the workpiece to the next process station.

[0008] By adopting the above technical scheme, the workpiece after processing enters the next process station through the unloading chute, the material shifting piece and the conveyor belt mechanism on the gear mechanism. The unloading mechanism can push the workpiece on the clamping mechanism, and then use the gear mechanism and the material shifting piece to transfer the workpiece to the conveyor belt mechanism. The entire unloading and material transfer process is realized by an automated mechanism with a high level of automation, making it more efficient and convenient to transfer the workpiece after processing to the next process station.

[0009] In a preferred example, the present invention can be further configured as follows: the gear mechanism includes a gear part and a gear driving source for driving the gear part to rotate, a suction hole for adsorbing the workpiece is provided in the discharge chute, an air suction source connected to the suction hole, and a baffle plate extending along the circumference of the gear part are provided on the frame, and the spacing between the baffle plate and the circumferential surface of the gear part is smaller than the diameter of the shaft part to prevent the workpiece from falling out of the discharge chute.

[0010] By adopting the above technical scheme, the suction hole plays a role of adsorbing and fixing the workpiece in the discharge chute, and the workpiece is transported stably and efficiently. The baffle plate can prevent the workpiece from escaping from the notch of the discharge chute, and the area between the baffle plate and the discharge chute forms a negative pressure area under the suction action of the suction hole. The pressure in this area is lower than the atmospheric pressure outside the baffle, so that the workpiece is subjected to a greater fixing pressure in the discharge chute, thereby improving the fixing effect of the workpiece.

[0011] In a preferred example, the present invention can be further configured as follows: the bottom surface of the material baffle plate is higher than the top surface of one end of the material-digging member, and one end of the material-digging member is integrally formed with an arc-shaped dipping piece for dipping materials.

[0012] By adopting the above technical solution, the arc-shaped pick makes it easy to push the workpiece out of the discharge chute, making it more convenient and quicker to separate the workpiece from the discharge chute, and also allows the workpiece to enter the conveying mechanism along the inclined surface of the material-pickup piece, making material-pickup more convenient and quick.

[0013] In a preferred example, the present invention can be further configured as follows: the unloading mechanism includes a unloading push rod and a unloading driving source for driving the unloading push rod to push the material, and the unloading driving source is installed on the frame.

[0014] By adopting the above technical solution, the unloading drive source drives the unloading push rod to work, and the unloading push rod pushes the workpiece out of the clamping mechanism. The setting of the unloading drive source and the unloading push rod makes unloading more automated and the production and processing efficiency of the workpiece is higher.

[0015] In a preferred example, the present invention can be further configured as follows: the frame is provided with a trigger switch that abuts against one end of the workpiece entering the discharge chute, and a controller electrically connected to the trigger switch and the gear drive source; the trigger switch is arranged opposite to the discharge push rod and are respectively located on both sides of the gear part.

[0016] By adopting the above technical solution, one end of the workpiece entering the unloading chute contacts the trigger switch, the trigger switch receives the contact signal, and controls the gear drive source through the controller, and the gear drive source drives the gear part to rotate, making the gear mechanism more efficient and energy-saving.

[0017] In a preferred example, the present invention can be further configured as follows: the slotting device includes cutting knives relatively arranged on two sides of the clamping mechanism, and a slotting driving source for driving the cutting knives to rotate.

[0018] By adopting the above technical solution, cutting knives are arranged on both sides of the clamping mechanism, and radial grooves are made on both ends of the shaft by the cutting knives. The grooves are made at both ends at the same time, which saves half of the groove processing time and greatly improves the groove efficiency.

[0019] In a preferred example, the present invention can be further configured as follows: the clamping mechanism includes an upper clamping arm, a lower clamping arm, a clamping drive, a lifting mounting plate and a lifting drive, the clamping drive drives the upper clamping arm and the lower clamping arm to clamp the workpiece, the upper clamping arm, the lower clamping arm and the clamping drive are installed on the lifting mounting plate, and the lifting drive drives the lifting mounting plate to rise and fall.

[0020] By adopting the above technical scheme, the clamping drive component realizes automatic clamping of the upper clamping arm and the lower clamping arm, and has the effect of automatically fixing the workpiece. The lifting drive component drives the lifting mounting plate to lift and lower, and realizes the lifting and lowering of the clamping mechanism, so that the workpiece on the clamping mechanism is sent to the slotting device and the unloading mechanism respectively, and the slotting action and the unloading action are performed respectively, thereby realizing the entire automated process of hole opening, grooving and unloading, and achieving high efficiency and low energy consumption in workpiece processing.

[0021] In a preferred example, the present invention can be further configured as follows: the feeding mechanism includes a feeding push rod and a feeding drive source, and the feeding drive rod source drives the feeding push rod to push the workpiece onto the clamping mechanism.

[0022] By adopting the above technical solution, the feed push rod, driven by the feed drive source, pushes the workpiece onto the clamping mechanism, completes the automatic pushing of the workpiece, realizes automatic loading of the workpiece before processing, and greatly improves efficiency.

[0023] In a preferred example, the present invention can be further configured as follows: a limiting component for limiting the workpiece from flying out of one end of the clamping mechanism is provided on the frame.

[0024] By adopting the above technical solution, the limit assembly restricts the workpiece from flying out from one end of the clamping mechanism, so that the workpiece can accurately fall on the clamping mechanism after coming out of the feeding mechanism, ensuring that the workpiece is accurately clamped and the accuracy of the connection between the feeding mechanism and the clamping mechanism is ensured.

[0025] In a preferred example, the present invention can be further configured as follows: the limit assembly includes a limit block that abuts against one end of the workpiece, and the limit block is arranged opposite to the feeding trough and is respectively located on both sides of the clamping mechanism.

[0026] By adopting the above technical solution, the limit block is opposite to the feeding trough, and the workpiece is easy to fly out of the clamping mechanism under the action of inertia after coming out of the feeding trough. The limit block contacts one end of the workpiece, and the moving stroke of the workpiece is well limited through the contact, ensuring that the workpiece is accurately clamped.

[0027] In summary, the present invention includes at least one of the following beneficial technical effects:

The workpiece rolling down from the lower end of the material-diverting piece 18 falls onto the conveyor belt 19.1, and is driven by the conveyor motor 19.3 to be transmitted to the next process station.

[0055] The implementation principle of this embodiment is as follows: the shaft workpiece enters the feeding trough 4.1 through the material placement trough 3.1, the feeding drive cylinder works to drive the feeding push rod to telescopically move in the feeding trough 4.1, and when the piston rod of the feeding drive cylinder is extended, the workpiece is pushed to the clamping mechanism 8 through the discharge hole 4.3 by the feeding push rod, and the workpiece coming out of the discharge hole 4.3 falls into the lower clamping groove 5.4, and the limit block 9.2 conflicts with one end of the workpiece to prevent the workpiece from flying out of the clamping mechanism 8, and the clamping drive cylinder works to drive the upper clamping arm 5.1 to approach the lower clamping arm 5.2, and the upper clamping arm 5.1 and the lower clamping arm 5.2 cooperate to clamp the workpiece, and the upper clamping groove 5.3 and the lower clamping groove 5.4 position the clamped workpiece, and the two ends of the clamped workpiece protrude from the two ends of the clamping mechanism 8.

[0056] The axial drive cylinder 10.4 works to drive the hole drill 10.1 to move in the axial direction of the workpiece, so that the hole drill 10.1 corresponds to the two end circumferential surfaces of the workpiece protruding from the clamping mechanism 8. The radial drive cylinder 10.5 works again to drive the hole drill 10.1 to approach the two ends of the workpiece. The hole driving rod motor works to drive the hole drill 10.1 to rotate through the pulley assembly 10.9, and the hole drill 10.1 drills the circumferential surface of the shaft.

[0057] After the drilling is completed, the lifting drive cylinder works to drive the lifting mounting plate 7 to descend to a certain height. During the descent, the slotting drive motor works to drive the cutting knife 13.1 to rotate, and the cutting knife 13.1 radially slots the two ends of the workpiece. After the slotting is completed, the lifting drive cylinder works to drive the lifting mounting plate 7 to continue to descend to a certain height until one end of the unloading push rod 15.1 corresponds to one end of the workpiece. The unloading drive cylinder works to push the workpiece out of one side of the clamping mechanism 8 through the unloading push rod 15.1. The pushed workpiece enters the unloading chute 14.4, and in the process of moving, the workpiece conflicts with the trigger switch 20 due to the inertial force of the push, and the trigger switch 20 transmits the contact signal to the controller 21, and the gear drive is controlled by the controller 21. The motor works, thereby driving the gear member 14.1 to rotate, and the gear member 14.1 drives the workpiece to move in the direction close to the material-pickup piece, and the suction hole 14.3 adsorbs the workpiece into the discharge chute 14.4, and the suction hole 14.3 quickly absorbs the air in the area between the baffle plate 16 and the discharge chute 14.4, so that the area becomes a negative pressure area 22, so that the workpiece is more firmly placed in the discharge chute 14.4 to prevent it from falling out of the discharge chute 14.4. When the workpiece moves to the arc-shaped paddle 18.1, the arc-shaped paddle 18.1 pulls the workpiece out of the discharge chute 14.4, and the pulled-out workpiece slides along the inclined surface of the material-pickup piece 18 to the conveyor belt mechanism 19, and the conveyor belt mechanism 19 conveys the processed workpiece to the next process station.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
