Abstract
Description
Technical Field
[0001] This invention relates to a machining equipment for grooving the surface of a shaft core. Background Technology
[0002] Existing shaft core surface grooving equipment typically requires machine downtime for loading or unloading operations during mass production. For example, after a workpiece is processed, the spindle or grooving mechanism must be stopped first, and then the finished product must be removed manually or by an auxiliary mechanism before the next workpiece is placed in for clamping and processing. This intermittent operation method results in long waiting times during loading and unloading, preventing the spindle and grooving mechanism from continuously operating, leading to low equipment utilization and difficulty in meeting the demands of large-scale, continuous production.
[0003] Therefore, it is necessary to make further improvements. Summary of the Invention
[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a processing equipment for slotting the surface of a shaft core, which can achieve continuous feeding, unloading and processing without stopping the machine.
[0005] To achieve the above objectives, the present invention provides a machining apparatus for grooving the surface of a shaft core, comprising: The main spindle has a channel extending along the axial direction in its middle part. The two ends of the channel correspond to the feed end and the discharge end of the main spindle, respectively. The feed end is equipped with a pneumatic clamp for holding the workpiece. At least one grooving mechanism is provided on one side of the feed end, and the grooving mechanism includes a movable table and a cutting tool fixed on the movable table. The feeding mechanism includes a feeding seat, a vibratory feeder, and a feeding cylinder. The feeding seat is located in front of the feed end and has a material groove that can accommodate a single workpiece. The material groove corresponds to the clamping port of the pneumatic fixture. The discharge end of the vibratory feeder is connected to the material groove. The feeding cylinder is located on the other end of the material groove relative to the pneumatic fixture, and the cylinder shaft of the feeding cylinder extends into the material groove. The discharge mechanism is located on the discharge end of the main shaft. The discharge mechanism includes a discharge seat, a discharge cylinder, and a fixed material seat. The discharge seat and the fixed material seat are slidably connected. The discharge seat has a fixed material port corresponding to the discharge end, and the fixed material port is open at the bottom. The cylinder shaft of the discharge cylinder is connected to the discharge seat. The discharge cylinder is used to drive the discharge seat to slide outward relative to the fixed material seat, so that the fixed material port is misaligned with the fixed material seat.
[0006] In one or more embodiments, a sensing mechanism is further included, the sensing mechanism including a fixed base, a piston rod and a sensor, the piston rod being telescopically connected to the fixed base, the end of the piston rod abutting against the feed inlet, and the sensor being disposed on the tail of the piston rod.
[0007] In one or more embodiments, a return spring is sleeved on the piston rod, and the two ends of the return spring abut against the end of the piston rod and the fixed seat, respectively.
[0008] In one or more embodiments, the sensor is a proximity switch or a touch switch.
[0009] In one or more embodiments, the fixed base is provided with a bracket, the bracket has a mounting slot extending along the extension and retraction direction of the piston rod, the mounting slot is provided with a fastening screw connected to the fixed base, and the sensor is mounted on the bracket.
[0010] In one or more embodiments, the discharge mechanism further includes a discharge channel, which is inclined and one end of the discharge channel extends in the sliding direction of the discharge seat.
[0011] In one or more embodiments, the number of grooving mechanisms is two, and the two grooving mechanisms are respectively arranged on the left and right sides of the feed end.
[0012] In one or more embodiments, the grooving mechanism further includes a drive cylinder for driving the moving platform to move.
[0013] In one or more embodiments, the discharge end of the vibratory feeder is connected to a universal bamboo tube, and the output end of the universal bamboo tube is provided with a discharge head, which is connected to the feeding seat.
[0014] Compared with the prior art, the advantages of this invention are as follows: This solution sets a channel in the middle of the main shaft and configures a pneumatic clamp at the feeding end, which, together with the vibratory plate and the feeding cylinder, realizes automatic continuous feeding. At the same time, the discharge cylinder drives the discharge seat to slide, so that the fixed material port and the fixed material seat are misaligned to realize automatic unloading. This allows the equipment to complete the entire process of feeding, clamping, processing and unloading without stopping the main shaft and the grooving mechanism. This effectively eliminates the waiting time for feeding and unloading, significantly improves the equipment utilization rate and production efficiency, meets the needs of large-scale continuous production, and has the advantages of high automation, compact structure, smooth unloading and reliable sensing and monitoring.

[0016] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.
[0017] See appendix Figure 1-3 This application provides a machining device for grooving the surface of a shaft core, comprising a spindle, at least one grooving mechanism, a feeding mechanism, and a discharging mechanism. A channel 1 extending along the axial direction is formed in the middle of the spindle, with the two ends of the channel 1 corresponding to the feed end and discharge end of the spindle, respectively. The workpiece enters the channel 1 from the feed end and is discharged from the discharge end after machining. A pneumatic clamp 2 is provided on the feed end for holding the workpiece. The pneumatic clamp 2 is used to clamp and fix the workpiece during machining, ensuring the accuracy and stability of the grooving process. The pneumatic clamp 2 can adopt a pneumatic gripper structure commonly used in the art, and the clamping and release of the workpiece is achieved by driving the gripper to open and close via a cylinder.
[0018] The grooving mechanism is located on one side of the feed end. The grooving mechanism includes a movable table 3 and a cutting tool 4 fixed on the movable table 3. The movable table 3 can move relative to the spindle, thereby driving the cutting tool 4 closer to or further away from the workpiece surface to achieve grooving. The cutting tool 4 can be a milling cutter, grinding wheel, or other cutting tools, depending on the processing requirements. In this embodiment, there are two grooving mechanisms, respectively located on the left and right sides of the feed end, allowing simultaneous grooving of both sides of the workpiece and improving processing efficiency. The grooving mechanism also includes a drive cylinder 20, which drives the movable table 3 to move, thereby achieving the feed and retraction of the cutting tool 4. The drive cylinder 20 can adopt a commonly used cylinder structure in the art, with its cylinder shaft connected to the movable table 3. The extension and retraction of the cylinder drives the movable table 3 to move along a set direction.
[0019] The feeding mechanism includes a feeding seat 5, a vibratory feeder 6, and a feeding cylinder 7. The feeding seat 5 is located in front of the feed end and has a trough that can accommodate a single workpiece, corresponding to the clamping opening of the pneumatic clamp 2. The discharge end of the vibratory feeder 6 is connected to the trough, and the vibratory feeder 6 is used to sort and transport the workpieces one by one into the trough. The feeding cylinder 7 is located on the other end of the trough relative to the pneumatic clamp 2, and the cylinder shaft 71 of the feeding cylinder 7 extends into the trough. When a workpiece enters the trough, the cylinder shaft 71 of the feeding cylinder 7 extends out, pushing the workpiece from the trough into the clamping opening of the pneumatic clamp 2, thus achieving automatic feeding.
[0020] Specifically, the discharge end of the vibratory feeder 6 is connected to a universal bamboo tube 21, and the output end of the universal bamboo tube 21 is provided with a discharge head 22, which is connected to the loading seat 5. The universal bamboo tube 21 can be bent and adjusted according to the actual installation position, so as to conveniently connect the discharge end of the vibratory feeder 6 to the material trough of the loading seat 5, ensuring smooth conveying of the workpiece.
[0021] The discharge mechanism is located on the discharge end of the main shaft. The discharge mechanism includes a discharge seat 8, a discharge cylinder 9, and a fixed seat 10. The discharge seat 8 is slidably connected to the fixed seat 10. The discharge seat 8 has a fixed port 11 corresponding to the discharge end, and the fixed port 11 opens downwards. After the workpiece is discharged from the discharge end of the main shaft, it enters the fixed port 11, which positions and accommodates the workpiece. The cylinder shaft 91 of the discharge cylinder 9 is connected to the discharge seat 8. The discharge cylinder 9 drives the discharge seat 8 to slide outwards relative to the fixed seat 10, causing the fixed port 11 to misalign with the fixed seat 10. When the discharge seat 8 slides outwards, misalignment occurs between the fixed port 11 and the fixed seat 10. The workpiece in the fixed port 11 loses the support of the fixed seat 10 and falls from the downward opening of the fixed port 11, thus achieving automatic unloading.
[0022] The discharge mechanism also includes a discharge channel 19, which is inclined and one end extends to the sliding direction of the discharge seat 8. When the workpiece falls from the fixed discharge port 11, the workpiece falls into the discharge channel 19 and slides out along the inclined discharge channel 19, achieving orderly collection.
[0023] The processing equipment in this embodiment also includes a sensing mechanism. The sensing mechanism includes a fixed base 12, a piston rod 13, and a sensor 14. The piston rod 13 is telescopically connected to the fixed base 12, and its end abuts against the feed inlet 11. When there is a workpiece in the feed inlet 11, the workpiece will press against the end of the piston rod 13, causing the piston rod 13 to retract towards the fixed base 12. The sensor 14 is located on the end of the piston rod 13 and is used to sense changes in the position of the piston rod 13, thereby determining whether there is a workpiece in the feed inlet 11. When there is a workpiece in the feed inlet 11, the piston rod 13 is pressed back by the workpiece, the sensor 14 senses the change in the position of the piston rod 13 and sends a signal, which the control system uses to control the discharge cylinder 9 to achieve automatic feeding.
[0024] A return spring 15 is sleeved on the piston rod 13, with its two ends abutting against the end of the piston rod 13 and the fixed seat 12, respectively. The return spring 15 is used to return the piston rod 13 to the extended state after the workpiece leaves the feed port 11, ensuring that the sensing mechanism can accurately detect whether the workpiece is in place for the next operation.
[0025] The sensor 14 is either a proximity switch or a touch switch. When the sensor 14 is a proximity switch, it senses the position change of the piston rod 13 tail in a non-contact manner; when the sensor 14 is a touch switch, it senses the position change of the piston rod 13 tail in a contact manner. The appropriate sensor type can be selected based on actual needs.
[0026] The mounting base 12 is equipped with a bracket 16, which has a mounting slot 17 extending along the extension direction of the piston rod 13. A fastening screw 18, connected to the mounting base 12, is located in the mounting slot 17. The sensor 14 is mounted on the bracket 16. By loosening the fastening screw 18, the position of the bracket 16 can be adjusted along the extension direction of the mounting slot 17, thereby adjusting the distance of the sensor 14 relative to the end of the piston rod 13 to accommodate different sensing sensitivities and installation requirements. After adjustment, the fastening screw 18 is tightened to fix the bracket 16 to the mounting base 12.
[0027] The above description is only a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present invention should be included within the scope of protection set forth in the claims.
