Description

Technical Field

[0001] This invention belongs to the field of automated conveying equipment technology, and specifically relates to an automatic feeding and conveying device for cylindrical parts. Background Technology

[0002] In the manufacturing of precision drill bits, the continuous and precise feeding and conveying of cylindrical metal raw materials is the core process to ensure processing efficiency and product accuracy. This process requires avoiding scratches on the surface of the metal raw materials during feeding and conveying, ensuring stable connection between the clamping fixture and the conveying structure and convenient assembly and disassembly, accurate positioning and smooth release of the fixture at the processing station, and efficient separation and classified collection of the fixture and the processed parts at the unloading end.

[0003] Currently, the industry mostly uses a vibratory feeder combined with a direct vibratory feeder for feeding cylindrical parts used in precision drill bit machining. The high-frequency vibration of the vibratory feeder can easily cause scratches on the surface of the metal raw material, affecting the precision of subsequent processing. The connection between the clamping fixture and the conveyor line is mostly fixed with bolts or simple clamps. Bolt fixing has low disassembly and assembly efficiency, and simple clamps lack anti-loosening structures, which can easily lead to fixture falling off and raw material deviation during the conveying process. The positioning and release of fixtures at the machining station mostly rely on electronic components and pneumatic components such as sensors, cylinders, and solenoid valves. The structure is complex and has a high failure rate in the dusty and oily environment of the machining workshop, resulting in high maintenance costs. The separation of fixtures and parts at the unloading end is mostly done manually or by electric push rods. Manual assistance is inefficient, and electric push rods also suffer from the problem of easy failure of electronic components.

[0004] The existing technology has at least the following problems in use: During the feeding and conveying of cylindrical metal raw materials for precision drill bit processing, the existing device is prone to scratching the surface of the raw material; the connection between the clamping tool and the conveyor line is poor and the anti-loosening effect is poor; the positioning and release of the tooling at the processing station relies on electronic and pneumatic components, resulting in complex structure and high failure rate; the separation efficiency of the tooling and parts at the unloading end is low, which affects the overall processing efficiency and product quality of precision drill bits. Summary of the Invention

[0005] This invention provides an automatic feeding and conveying device for cylindrical parts, which solves the technical problems of easy scratching of cylindrical metal raw materials during the feeding and conveying of precision drill bit processing, poor anti-loosening effect of tooling and conveyor line connection, high failure rate of tooling positioning and release at the processing station relying on electronic and pneumatic components, and low separation efficiency of tooling and parts at the unloading end.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: An automatic feeding and conveying device for cylindrical parts includes: a frame; a stacking and feeding assembly installed at the feeding end of the frame, the stacking and feeding assembly including a stacking unit and a pushing unit, the stacking unit having a funnel-shaped structure adapted for stacking cylindrical metal raw materials, the pushing unit being arranged along the discharge direction of the stacking unit for continuously pushing the cylindrical parts to a subsequent conveying structure; a conveyor line assembly installed on the frame along the length direction of the frame, the conveyor line assembly including a conveying track and connecting units, the connecting units being evenly arranged on the conveying track and having connecting parts and anti-loosening parts for achieving detachable connection with tooling; and a clamping tooling. The tooling is adapted and installed on the connecting unit, and has a clamping part and an adapter part. The clamping part is used to engage and fix the cylindrical parts, and the adapter part is adapted to the connecting part of the connecting unit to realize linkage with the conveyor line assembly. The station positioning assembly is installed on the frame corresponding to the processing station. The station positioning assembly includes an engaging part and a releasing part to realize the positioning, clamping and releasing of the clamping tooling. The unloading and collecting assembly is installed at the unloading end of the frame. The unloading and collecting assembly includes a stripping part and a collecting unit.

[0007] Furthermore, the stacking unit is a funnel-shaped stacking trough, with a feeding port at the bottom. The width of the feeding port is slightly larger than the outer diameter of the cylindrical component. The pushing unit includes a push plate, a guide rod, and a linear drive. The guide rod is mounted on the frame along the discharge direction of the stacking trough. The push plate is slidably fitted on the guide rod, and the surface of the push plate is in contact with the inner wall of the stacking trough. The output end of the linear drive is connected to the push plate, driving the push plate to reciprocate linearly along the guide rod to achieve continuous pushing of the cylindrical component.

[0008] Furthermore, the conveying track is a chain plate guide rail, and the conveying line assembly also includes a transmission component and a drive motor. The transmission component is mounted on the transmission end of the chain plate guide rail, and the connecting unit is uniformly fixed on the transmission component. The drive motor is connected to the transmission component and drives the connecting unit to perform continuous cyclic movement along the chain plate guide rail. The connecting part is a boss-shaped locking protrusion, and the anti-loosening part is an elastic latch. The elastic latches are symmetrically distributed on both sides of the locking protrusion, and the elastic latches have an elastic tendency to open outward.

[0009] Furthermore, the adapter is a groove-shaped snap-fit ​​groove that matches the snap-fit ​​protrusion. The inner wall of the snap-fit ​​groove is provided with an anti-loosening groove that cooperates with the elastic snap tongue. The clamping part is an arc-shaped groove. The arc-shaped groove is opened on the top of the clamping fixture. Its curvature matches the outer diameter of the cylindrical part. The inner wall of the arc-shaped groove is provided with anti-slip protrusions to enhance the friction with the cylindrical part.

[0010] Furthermore, the engaging part includes a positioning base, an inclined clamping block, and a reset elastic element. The positioning base is fixed on the frame, and its inner wall is an arc-shaped structure adapted to the outer wall of the clamping fixture. The inclined clamping block is slidably installed on both sides of the positioning base, and its end facing the clamping fixture is an inclined structure. The reset elastic element is fitted on the outer side of the inclined clamping block, and its two ends abut against the positioning base and the inclined clamping block respectively, driving the inclined clamping block to press against the clamping fixture, thereby realizing the positioning and engaging of the clamping fixture.

[0011] Furthermore, the release part is a cam push rod assembly, which includes a linkage cam and a push rod. The linkage cam is linked to the transmission component of the conveyor assembly. One end of the push rod is in rolling contact with the wheel surface of the linkage cam, and the other end abuts against the inclined surface clamping block. The linkage cam rotates with the transmission component, pushing the push rod to make linear motion, thereby pushing the inclined surface clamping block to compress and retract the reset elastic element, thus realizing the release of the clamping fixture.

[0012] Furthermore, the unloading section includes a wedge-shaped unloading block, which is fixed to the unloading end of the frame; a guide plate is provided between the wedge-shaped unloading block and the conveyor assembly, and a guide groove is provided on the guide plate. The guide groove is used to accommodate and engage the push rod, and to limit and guide the movement of the push rod.

[0013] Furthermore, the stripping section also includes an external pneumatic gripper and a pneumatic clamping seat. The pneumatic clamping seat is installed at the bottom of the wedge-shaped stripping block and is used to abut against the clamping fixture from the side. The pneumatic gripper grips and transfers the processed parts.

[0014] Furthermore, the material collection unit includes a component collection trough and a tooling collection bin. The outlet end of the guide plate corresponds to the component collection trough. The tooling collection bin is located below the side of the wedge-shaped stripper block, corresponding to the detachment trajectory of the clamping tool, and is used for collecting the clamping tool.

[0015] Furthermore, it also includes multiple pressure sensors and photoelectric sensors. The photoelectric sensors are installed in the processing area of ​​the conveyor assembly to collect the position signal of the clamping fixture. The pressure sensors are installed in the processing areas of the wedge-shaped stripper block and the conveyor assembly to collect the position signal of the clamping fixture.

[0016] This invention provides an automatic feeding and conveying device for cylindrical parts, with the following advantages: By using a funnel-shaped material trough combined with a polyurethane pusher plate, it replaces the traditional vibratory feeder, achieving continuous, vibration-free feeding of cylindrical metal raw materials, effectively avoiding surface scratches and ensuring the precision of raw materials for precision drill bit processing; Through the engaging engagement of the snap-fit ​​protrusion and snap-fit ​​groove, combined with the anti-loosening structure of the elastic latch and anti-loosening groove, a detachable and stable connection between the clamping fixture and the conveyor line is achieved, ensuring connection reliability during conveying and facilitating fixture disassembly and replacement; The mechanical engagement and positioning of the clamping fixture is achieved through the cooperation of the inclined clamping block and the reset elastic element, combined with the cam push rod assembly linked to the conveyor line drive to achieve electro-mechanical release of the fixture, eliminating electronic and pneumatic components, resulting in a simple structure and... Adaptable to dusty and oily workshop environments, it boasts a low failure rate and low maintenance costs. The wedge-shaped stripper block's inclined surface extrusion enables the elastic tongue to retract, achieving purely mechanical separation between the clamping fixture and the connecting unit. Combined with an inclined guide plate and a categorized material collection structure, it achieves efficient separation and categorized collection of processed parts from the fixture, improving overall material handling efficiency. The plastic clamping fixture, coupled with an arc-shaped anti-slip groove, avoids scratching cylindrical raw materials by metal fixtures while ensuring clamping stability and preventing material deviation and rotation during transport and processing. The closed-loop conveyor track design enables continuous cyclic transport of the clamping fixture. Combined with an integrated structure for loading, processing, and unloading, it significantly improves the loading and conveying efficiency of cylindrical parts, meeting the continuous processing needs of precision drill bits.

[0024] Example: like Figures 1 to 6 As shown, this embodiment provides an automatic feeding and conveying device for cylindrical parts, including: a frame 1; a stacking and feeding assembly 2, installed at the feeding end of the frame 1, the stacking and feeding assembly 2 including a stacking unit and a pushing unit, the stacking unit having a funnel-shaped structure adapted for stacking and storing cylindrical metal raw materials, the pushing unit being arranged along the discharge direction of the stacking unit for continuously pushing the cylindrical parts to the subsequent conveying structure; a conveyor line assembly 3, installed on the frame 1 along the length direction of the frame 1, the conveyor line assembly 3 including a conveying track and a connecting unit, the connecting units being evenly arranged on the conveying track and having a connecting part and an anti-loosening part for achieving a detachable connection with the tooling; and a clamping tooling 4, the clamping tooling 4 being adapted to be installed on the connecting unit, having a clamping part and an anti-loosening part. The fitting part and clamping part are used to lock and fix the cylindrical parts. The adapter part is adapted to the connecting part of the connecting unit to realize the linkage with the conveyor assembly 3. The station positioning assembly 5 is installed on the frame 1 corresponding to the processing station. The station positioning assembly 5 includes a locking part and a releasing part to realize the positioning, clamping and releasing of the clamping fixture 4. The unloading and collecting assembly 6 is installed at the unloading end of the frame 1. The unloading and collecting assembly 6 includes a stripping part and a collecting unit. The stripping part is used to separate the clamping fixture 4 from the connecting unit. The collecting unit realizes the classified collection of the processed cylindrical parts and the detached clamping fixture 4. The photoelectric sensor and the pressure sensor are respectively arranged in the processing area of ​​the conveyor line and the position of the wedge stripping block 61 to collect the fixture position signal in real time to complete the automatic linkage of the whole machine.

[0025] In this embodiment, the frame 1 is made of industrial aluminum profile splicing and is equipped with adjustable support pads at the bottom to adapt to uneven workshop floors; the whole machine is arranged in a straight line with loading, processing and unloading stations, and the processing station is set in the middle of the conveyor line, which can be directly connected to precision machining equipment for cylindrical parts such as lathes and milling machines; the workpiece to be processed is stainless steel cylindrical bar stock, and the device can be compatible with various cylindrical parts with different outer diameters and lengths by changing different specifications of clamping fixtures 4. All functional modules of the whole machine are modularly assembled, which facilitates individual disassembly and maintenance and the addition of auxiliary mechanisms in the later expansion.

[0026] Furthermore, the stacking unit is a funnel-shaped stacking trough 21, with a feeding port 22 at the bottom of the stacking trough 21. The width of the feeding port 22 is slightly larger than the outer diameter of the cylindrical component. The pushing unit includes a push plate 23, a guide rod 24, and a linear drive component 25. The guide rod 24 is installed on the frame 1 along the discharge direction of the stacking trough 21. The push plate 23 is slidably fitted on the guide rod 24, and the surface of the push plate 23 is in contact with the inner wall of the stacking trough 21. The output end of the linear drive component 25 is connected to the push plate 23, driving the push plate 23 to reciprocate linearly along the guide rod 24 to realize the continuous pushing of the cylindrical component.

[0027] In this embodiment, the material stacking trough 21 is made of stainless steel welded as a whole, and the inner wall is mirror polished to reduce the sliding friction of the raw materials; the width of the feeding port 22 is only 1~2mm larger than the outer diameter of the workpiece, allowing only a single cylindrical raw material to pass through at a time, eliminating the failure of stacked material jamming; the guide rod 24 adopts a double parallel stainless steel optical shaft with linear bearing to support the push plate 23, and a supply structure is added to the guide rod 24. The existing spring clip type feeding device is used to intermittently supply the clamping fixture 4, and the clamping fixture 4 is added in front of the guide rod 24. The drive optical shaft moves along the distribution direction of the guide rod 24, thereby pushing the raw material to be processed into the clamping fixture 4; the push plate 23 is made of polyurethane soft material to avoid scratching the surface of the metal workpiece during the pushing process; the linear drive component 25 is a lead screw stepper motor, and the controller can freely adjust the pushing reciprocating speed and stroke. The motor has a dustproof protection structure, and an assembly device is set between the pushing unit and the conveying track. The assembly device adopts a crawler type transmission structure to move the assembled clamping fixture 4 with the raw material pressed into the conveying track.

[0028] Furthermore, the conveying track is a chain plate guide rail 31, and the conveying line assembly 3 also includes a transmission component 32 and a drive motor 33. The transmission component 32 is fitted on the transmission end of the chain plate guide rail 31, and the connecting unit is evenly fixed on the transmission component 32. The drive motor 33 is connected to the transmission component 32, and the drive connecting unit is driven to make continuous cyclic movement along the chain plate guide rail 31. The connecting part is a boss-shaped locking protrusion 34, and the anti-loosening part is an elastic latch 35. The elastic latch 35 is symmetrically distributed on both sides of the locking protrusion 34, and the elastic latch 35 has an elastic tendency to open outward.

[0029] In this embodiment, the chain guide rail 31 is a closed-loop circulating synchronous belt guide rail, the transmission component 32 is a toothed synchronous belt, and the tensioning wheel can adjust the tension of the synchronous belt to ensure conveying accuracy; the drive motor 33 is a reduction stepper motor, which supports stepless speed regulation of the conveyor line to match the processing cycle of different equipment; the locking protrusion 34 is a cylindrical boss, and the elastic latches 35 on both sides are made of stainless steel springs. By setting a linear electromagnetic drive structure, the elastic latches 35 are driven to retract into the locking protrusion 34. When the clamping fixture 4 reaches the processing position, the constraint of the electromagnetic drive structure is released, and the elastic latches 35 extend to assist in the positioning of the clamping fixture 4, connecting the single... The original design employs an electromagnetic structure. A signal-controlled electromagnetic device is installed directly below the chain guide rail 31 to fix the installation and connection posture of the push rod 542. Correspondingly, after adopting electromagnetic control, a permanent magnet is installed at the bottom of the push rod 542, and guide rods 36 are symmetrically arranged on both sides of the chain plate along the movement direction of the chain plate. These guide rods 36 are used to limit the movement of parts during the transport process and prevent tools in the processing area from intruding into the chain plate transport area. Specifically, in actual use, the distribution height of the guide rod 36 is changed by adjusting the distribution height of the threaded rod of the mounting seat of the guide rod 36 to adapt to clamping fixtures 4 of different heights.

[0030] Furthermore, the adapter is a groove-shaped locking groove 41 that matches the locking protrusion 34. The inner wall of the locking groove 41 is provided with an anti-loosening groove 42 that cooperates with the elastic locking tongue 35. The clamping part is an arc-shaped groove 43. The arc-shaped groove 43 is opened on the top of the clamping fixture 4. Its curvature matches the outer diameter of the cylindrical part. The inner wall of the arc-shaped groove 43 is provided with anti-slip protrusions 44 to enhance the friction with the cylindrical part.

[0031] In this embodiment, the clamping fixture 4 is injection molded from lightweight and wear-resistant PP plastic; the snap-fit ​​groove 41 and the snap-fit ​​protrusion 34 are fitted with a clearance fit for easy and quick assembly and disassembly; the anti-loosening snap-fit ​​groove 42 is completely fitted with the contour of the elastic snap-fit ​​tongue 35, which can simultaneously limit the axial and radial sway of the fixture; the arc-shaped snap-fit ​​groove 43 has a semi-circular arc structure, and the anti-slip protrusion 44 on the inner wall is integrally injection molded from rubber protrusions, which increases the workpiece clamping friction, prevents the cylindrical part from rotating and slipping during processing, and does not leave indentations on the outer wall of the workpiece.

[0032] Furthermore, the engaging part includes a positioning base 51, an inclined clamping block 52, and a reset elastic member 53. The positioning base 51 is fixed on the frame 1, and its inner wall is an arc-shaped structure that matches the outer wall of the clamping fixture 4. The inclined clamping block 52 is slidably installed on both sides of the positioning base 51, and its end facing the clamping fixture 4 is an inclined structure. The reset elastic member 53 is fitted on the outer side of the inclined clamping block 52, and its two ends abut against the positioning base 51 and the inclined clamping block 52 respectively, driving the inclined clamping block 52 to press against the clamping fixture 4, thereby realizing the positioning and engaging of the clamping fixture 4.

[0033] In this embodiment, the positioning bracket 51 is made of a hard material to reduce frictional wear with the plastic tooling; the end slopes of the inclined clamping blocks 52 on both sides form an inlet guide structure; the reset elastic element 53 is a miniature compression spring, which can automatically push the clamping blocks open when the tooling enters the bracket, and the spring assists in rebounding and clamping the tooling after it is in place.

[0034] Furthermore, the release part is a cam push rod assembly 54, which includes a linkage cam 541 and a push rod 542. The linkage cam 541 is linked to the transmission component 32 of the conveyor assembly 3. One end of the push rod 542 rolls in contact with the wheel surface of the linkage cam 541, and the other end abuts against the inclined surface clamping block 52. The linkage cam 541 rotates with the transmission component 32, pushing the push rod 542 to make linear motion, thereby pushing the inclined surface clamping block 52, retracting the reset elastic element 53, and realizing the release of the clamping fixture 4.

[0035] In this embodiment, the linkage cam 541 is synchronously linked with the conveyor transmission component 32 through the synchronous wheel, and the rotation of the cam is completely synchronized with the tooling conveying action; the bottom of the push rod is provided with a drive plate, and there are two eccentric cams. The two eccentric cams act on the same drive plate at the same time, thereby pushing the push rod on the drive plate. Because there is a fixed structure for the positioning bracket, when the cam rotates eccentrically, the push rod 542 pushes the two side clamping blocks in a straight line to retract synchronously, completely releasing the tooling, and relying on the power of the conveyor line itself to complete the release of the workstation.

[0036] Furthermore, the unloading section includes a wedge-shaped unloading block 61, which is fixed to the unloading end of the frame 1; a guide plate 64 is provided between the wedge-shaped unloading block 61 and the conveyor assembly 3, and a guide groove is provided on the guide plate 64. The guide groove is used to accommodate and engage the push rod 542, and to limit and guide the movement of the push rod 542.

[0037] In this embodiment, the wedge-shaped stripper block 61 is made of low-friction polytetrafluoroethylene, with its inclined surface facing directly upward. The retracting spring assists in the clamping fixture 4 to exit the positioning bracket 51, releasing the locking between the fixture and the connecting unit. The guide plate 64 is arranged at the front end of the unloading station, with a long guide groove on its surface. The push rod 542 slides inside the guide groove throughout its entire movement. The guide groove constrains the push rod 542 to shift left and right, ensuring that the push rod 542 is always directly facing the inclined clamping block 52, thus preventing misalignment during pushing and causing the fixture to fail to release properly.

[0038] Furthermore, the stripping section also includes an external pneumatic gripper and a pneumatic clamping seat. The pneumatic clamping seat is installed at the bottom of the wedge-shaped stripping block 61 and is used to abut against the clamping fixture 4 from the side. The pneumatic gripper grabs and transfers the processed parts.

[0039] In this embodiment, the pneumatic clamping seat is fixed below the wedge-shaped stripper block 61. When the tooling moves to the unloading position, the clamping seat abuts against the tooling body from both sides to prevent the tooling from tipping over or shifting when it is detached. The pneumatic gripper is installed on the side of the unloading station. After the mechanical stripping releases the tooling lock, the gripper extends precisely to grab the finished workpiece in the arc-shaped slot 43. The double unloading improves the tooling detachment and realizes the automatic transfer of the finished workpiece, thereby improving the degree of automation of unloading.

[0040] Furthermore, the material collection unit includes a component collection trough 62 and a tooling collection bin 63. The outlet end of the guide plate 64 corresponds to the component collection trough 62. The tooling collection bin 63 is located on the side and below the wedge-shaped stripping block 61, corresponding to the falling trajectory of the clamping tool 4, and is used to clamp and collect the tool 4.

[0041] In this embodiment, the component collection trough 62 is equipped with a buffer structure to prevent precision cylindrical workpieces from falling and being damaged. The trough outlet can be connected to subsequent storage equipment. The tooling collection bin 63 is a drawer-type plastic bin with a sponge buffer layer inside. After the tooling falls off, it falls directly into the bin for centralized recycling. The drawer-type structure can be pulled out directly, making it convenient for operators to collect the tooling for recycling without stopping the machine to clean the tooling.

[0042] Furthermore, it also includes multiple pressure sensors and photoelectric sensors. The photoelectric sensors are set in the processing area of ​​the conveyor assembly 3 to collect the position signal of the clamping fixture 4, and the pressure sensors are set in the processing area of ​​the wedge-shaped stripper block 61 and the conveyor assembly 3 to collect the position signal of the clamping fixture 4.

[0043] In this embodiment, photoelectric sensors are arranged in pairs before and after the processing station. When the tooling enters or leaves the processing area, a position signal is triggered in real time. After receiving the signal, the controller controls the start and stop of the processing equipment. Pressure sensors are respectively installed at the contact positions of the positioning bracket 51 and the wedge-shaped stripper block 61. After the tooling is in place, the sensor is pressed and generates a signal to verify whether the tooling is accurately engaged and completely stripped. The sensor signal is connected to the whole machine controller to form a closed-loop control. When tooling misalignment or jamming occurs, the machine will automatically stop and alarm to avoid equipment collision damage.

[0044] In summary, this invention utilizes a funnel-shaped material trough 21 paired with a reciprocating pushing unit, relying on a linear drive component 25 to smoothly push raw materials, replacing the vibratory feeder and avoiding scratches on the surface of cylindrical metal workpieces, thus ensuring the surface accuracy of the workpiece before processing. The snap-fit ​​protrusion 34, in conjunction with a detachable clamping fixture 4 with an elastic latch 35, enables rapid disassembly and replacement of the fixture. The elastic latch 35, in conjunction with the anti-loosening groove 42, prevents conveying swaying and is suitable for continuous conveying of various specifications of cylindrical parts. Furthermore, the inclined plane clamping block 52 provides mechanical positioning and... The conveyor line linkage cam 541 and push rod 542 release mechanism reduce the probability of equipment failure in dusty and oily environments; the push rod 542 is limited by the guide plate 64 with guide groove, and together with the wedge-shaped stripping block 61, pneumatic clamping seat and pneumatic gripper, a double stripping and unloading structure is formed, which not only ensures the precise and non-deviational movement of the push rod 542, but also helps to realize the automatic separation and gripping of tooling and finished workpieces, improving unloading efficiency; the sorting and collection unit realizes the partitioned recycling of workpieces and tooling, and the tooling position is monitored in a closed loop by photoelectric and pressure sensors.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope described in the present invention should be included within the scope of protection of the present invention.
