[0022] like Figures 1 to 4As shown, it is the structure schematic diagram of the diaphragm pump connecting rod shaft processing special line provided by the utility model. The diaphragm pump connecting rod shaft processing special line includes one feeding mechanism 10, one numerical control lathe 20 arranged in the logistics direction of the feeding mechanism 10, one double-end processing equipment 30 arranged at one side of the numerical control lathe 20, one centerless grinding machine 40 arranged at one side of the double-end processing equipment 30, one material moving mechanism 50 erected above the numerical control lathe 20, the double-end processing equipment 30 and the centerless grinding machine 40, and one discharging mechanism 60 arranged in the logistics direction of the centerless grinding machine 40. It can be conceived that the diaphragm pump connecting rod shaft processing special line also includes other functional modules such as a waste chip collecting box, an electrical control cabinet and the like, which are the technology known to the person skilled in the art and will not be described one by one here.

[0023] The feeding mechanism 10 is a feeding device for transporting shaft products and includes a rack 11 arranged on the equipment plane, a feeding flow channel 12 erected on the rack 11, and a feeding rod 13 connecting the feeding mechanism 10 and the numerical control lathe 20.

[0024] The rack 11 is two vertical columns fixed on the equipment plane by fasteners, used for supporting the feeding flow channel and can be provided with a lifting structure to facilitate adjusting the equipment height.

[0025] The feeding flow channel 12 is a logistics channel for transporting products, which can be driven by a conveying belt to move along the feeding flow channel 12, and is a common technology widely used in the mechanical production technical field and not the main content of the present application, so only a brief description is made here.

[0026] One end of the feeding rod 13 is arranged in the feeding flow channel 12, and the other end is inserted into the numerical control lathe 20, so that the cylindrical product is sleeved on the feeding rod 13 and transported along the feeding rod 13 to the numerical control lathe 20 for machining. Specifically, a pushing turntable can be arranged in the feeding flow channel 12, which makes the product move along the feeding rod 13 by rotating and rubbing the surface of the product, and a plurality of products are transported forward by being pushed one by one. The feeding rod 13 can also be connected to a straight vibration feeder for feeding by vibration, which is not limited specifically here.

[0027] The CNC lathe 20 is one of the most widely used CNC machine tools, mainly used for cutting the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. It can also perform grooving, drilling, reaming, boring, and other machining operations. CNC machine tools automatically process parts according to pre-programmed machining procedures. This is an existing technology widely used in industrial production and should be well-known to those skilled in the art; therefore, only a brief description is provided here. The CNC lathe 20 includes a working port 21, a chuck 22 located at the working port 21, and a movable cutting head 23 located within the CNC lathe 20. The working port 21 is located in the center of the CNC lathe 20, allowing the machined product to be clamped from the working port 21. The chuck 22 is located within the CNC lathe 20 and is used to clamp the product for machining operations. The free end of the feed bar 13 passes through the center of the chuck 22 so that the product can be transported along the feed bar 13 to the chuck 22. After being clamped by the chuck 22, the moving cutter head 23 approaches and performs the operation.

[0028] The CNC lathe 20 is also equipped with a number of other components, including but not limited to CNC devices, bed, spindle box, tool post feed system, tailstock, hydraulic system, cooling system, lubrication system, chip conveyor, etc. These are all commonly used technologies in industrial production equipment, and therefore are not listed one by one in the instruction manual and accompanying drawings.

[0029] The dual-head machining equipment 30 includes a double-end bed 31, two dual-axis displacement assemblies 32 disposed on the double-end bed 31, a pusher assembly 33 disposed on the dual-axis displacement assembly 32, a clamping assembly 34 disposed between the two dual-axis displacement assemblies 32, two rotary turret assemblies 35 respectively disposed on the two dual-axis displacement assemblies 32, and a fly cutter disc 36 disposed on one of the dual-axis displacement assemblies 32.

[0030] The double-ended bed 31 serves as a base for supporting the various functional modules of the aforementioned double-head machining equipment 30, and may be made of stainless steel or alloy. The table surface of the double-ended bed 31 is inclined, including two chip-collecting inclined surfaces 311 located at both ends of the double-ended bed 31, and a chip-discharging inclined surface 312 located in the center of the double-ended bed 31. Both chip-collecting inclined surfaces 311 are inclined towards the chip-discharging inclined surface 312 and are symmetrical to each other, so that waste chips falling on the chip-collecting inclined surfaces 311 will slide into the chip-discharging inclined surface 312. The chip-discharging inclined surface 312 is located between the two chip-collecting inclined surfaces 311, and its inclination direction is towards one side of the double-ended bed 31. Specifically, the sliding direction of waste chips in the chip-discharging inclined surface 312 is perpendicular to the sliding direction in the two chip-collecting inclined surfaces 311, so as to discharge waste chips from the double-ended bed 31, and can be quickly collected by setting a chip collection box.

[0031] The two dual-axis displacement components 32 are symmetrically arranged on both sides of the pusher component 33, and each includes two sets of vertically arranged slide rail structures, thereby realizing movement along the two vertical directions of the X-axis and Y-axis on the same plane. Its structure and working principle should be existing technology. Each set of slide rail structures includes components such as servo motor, slide rail, slider and connecting plate, which will not be described in detail here.

[0032] The pushing assembly 33 includes a pushing placement block 331 disposed on one of the dual-axis displacement assemblies 32, a loading cylinder 332 disposed on the pushing placement block 331, and a unloading cylinder 333 disposed on the other dual-axis displacement assembly 32. The pushing placement block 331 is fixed to the connecting plate of the dual-axis displacement assembly 32 and is provided with a circular placement groove, the groove extending towards the clamping assembly 34 for placing the product. The loading cylinder 332 is disposed on the side of the pushing placement block 331 away from the clamping assembly 34, and has a pushing block on its driving end, the driving direction being towards the clamping assembly 34, so that after the product is placed on the pushing placement block 331, it is pushed and inserted into the clamping assembly 34 by the loading cylinder 332. The feeding cylinder 333 is mounted on the dual-axis displacement assembly 32 on the other side of the clamping assembly 34. A push block is mounted on the driving end, and the driving direction is toward the clamping assembly 34 to push out the product clamped in the clamping assembly 34.

[0033] The clamping assembly 34 includes a spindle clamp 341 mounted on the double-ended bed 31, a clamping turntable 342 mounted on the spindle clamp 341, and a drive motor 343 connected to the clamping turntable 342. The spindle clamp 341 is fixed to the double-ended bed 31 by fasteners and is located at the center of the double-ended bed 31, on the axis of symmetry of the two dual-axis displacement assemblies 32. The clamping turntable 342 is a turntable mounted on the spindle clamp 341, and its rotation direction is the same as the axial direction of the clamping turntable 342 and the driving direction of the pushing assembly 33. A clamping plate is provided in the middle of the clamping turntable 342 for clamping the product. The rotation of the clamping turntable 342 drives the product to rotate. The drive motor 343 can be a servo motor, which is located on one side of the spindle clamp 341 and connected to the clamping turntable 342 via a belt, and is used to provide driving force for the rotation of the clamping turntable 342.

[0034] The rotary turret assembly 35 is a tool magazine with a rotary table. The tool magazine system is a device that provides the tool storage and changing capabilities required in automated machining processes. Its automatic tool changing mechanism and tool magazine, capable of storing multiple tools, change the traditional manual production method. Through computer program control, various machining requirements can be met, such as milling, drilling, boring, and tapping, significantly shortening machining time and reducing production costs. Its structure and working principle are existing technology and well-known to those skilled in the art, therefore, they will not be described in detail here. In this embodiment, each rotary turret assembly 35 is equipped with four cutting heads: a face tool, a center drill, a drill bit, and a tap. The rotary table is rotated by hydraulic or pneumatic pressure, causing the corresponding cutting head to rotate towards the clamping assembly 34 to perform the machining operation on the product.

[0035] The fly cutter head 36 is a CNC fly cutter head, a type of cutting tool used on CNC machine tools, mainly for machining planes and contours. Its working principle involves the synchronous rotation of the fly cutter head's power head and the spindle to achieve cutting of the workpiece. Its structure and working principle are existing technology and well-known to those skilled in the art, therefore they will not be described in detail here. In this embodiment, the fly cutter head 36 is mounted on the dual-axis displacement assembly 32. The fly cutter head 36 moves closer to the product via the movement on the dual-axis displacement assembly 32 and cuts one end of the product.

[0036] The centerless grinder 40 described above is a type of grinder that performs grinding without requiring a workpiece axis for positioning. It mainly consists of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece support. In a centerless cylindrical grinder, the workpiece is not centered or supported by a center; instead, it is placed between the grinding wheel and the guide wheel, supported by a support plate and the guide wheel. The centerless grinder can automatically dress and compensate. The machine tool is equipped with an automatic loading and unloading mechanism and can perform automatic cyclic grinding. Its structure and working principle are existing technologies, such as the detailed description of a special CNC centerless grinder disclosed in Chinese patent CN202411252224.1. Therefore, only a brief description is provided here. The centerless grinder 40 is also provided with a belt conveyor 41 that passes through the middle of the centerless grinder 40. One end is located on one side of the double-head processing equipment 30, and the other end is located on one side of the unloading mechanism 60. Specifically, after the product is processed on the double-head processing equipment 30, it is moved to the belt conveyor 41 by the clamping of the transfer mechanism 50. Driven by the belt, it passes through the centerless grinder 40 and grinds the surface of the product. After grinding, it continues to move along the belt conveyor 41 to the side of the unloading mechanism 60, where the unloading operation is performed.

[0037] The material transfer mechanism 50 includes a frame 51, a three-axis crane 52 mounted on the frame 51, a gripper connecting block 53 mounted on the three-axis crane 52, a rotating assembly 54 mounted on the gripper connecting block 53, an L-shaped connecting plate 55 mounted on the rotating assembly 54, and two gripper assemblies 56 mounted on the rotating assembly 54.

[0038] The truss 51 spans above the CNC lathe 20, the double-head machining equipment 30, and the centerless grinder 40. The three-axis crane 52 includes a track arranged along the length of the truss 51 and a crane mounted on the track. A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range; it is also called an overhead crane, gantry crane, or hoist. The three-axis crane 52 can move in three vertical planes: the X-axis, Y-axis, and Z-axis. Both the truss 51 and the three-axis crane 52 are existing technologies in the field of manufacturing processes and should be well known to those skilled in the art; therefore, only a brief description is provided here.

[0039] The gripper connecting block 53 is mounted on the three-axis crane 52 and located at the end of the vertical lifting end for setting grippers to pick up products.

[0040] The rotating assembly 54 can be a pneumatic turntable, and its rotation direction is inclined at a 45° angle to the lifting direction of the three-axis crane 52. The pneumatic turntable is a rotating device driven by a pneumatic device; its working principle is based on the mechanical principles of aerodynamics and rotational motion, and it is existing technology, so it will not be elaborated further here. By rotating the rotating assembly 54, the two gripper assemblies 56 are rotated to vertically downward gripping positions, enabling the material transfer mechanism 50 to grip multiple sets of products at once, thus improving the efficiency of material transfer.

[0041] The L-shaped connecting plate 55 is disposed on the rotating end of the rotating assembly 54, and the axial direction of the rotating assembly 54 is disposed toward the right-angle connection of the L-shaped connecting plate 55, so that both plate surfaces of the L-shaped connecting plate 55 are inclined at a 45° angle to the rotating plane of the rotating assembly 54, so that when the rotating assembly 54 rotates, the plate surfaces of the L-shaped connecting plate 55 are facing the vertical and horizontal directions.

[0042] Each of the gripper assemblies 56 is a structure consisting of multiple pneumatic grippers stacked together for gripping products of longer length. Alternatively, grippers with a certain length can be used; no specific limitation is made here. The gripper assembly 56 is rotated to face the product via the rotating assembly 54, thereby gripping the product.

[0043] The feeding mechanism 60 includes a frame 61, a tray 62 disposed on the frame 61, a three-axis moving assembly 63 disposed on one side of the tray 62, and a feeding assembly 64 disposed on the three-axis moving assembly 63.

[0044] The frame 61 can be a frame structure constructed from stainless steel pipes or aluminum profiles, used to support the various structures of the unloading mechanism 60, and is equipped with multiple other components, including but not limited to equipment planes, cabinet door side panels, and fixed supports, all of which are common technologies used in industrial production equipment, and therefore will not be described in detail here. The frame 61 is located on one side of the end of the belt conveyor 41 to facilitate the unloading assembly 64 to unload products that have completed grinding operations in the centerless grinder 40.

[0045] The tray 62 is a rectangular tray located on the frame 61. It can be placed on a roller conveyor line to facilitate the transport of the tray 62 filled with products. The roller conveyor line and the corresponding transport structure are existing technologies in the field of process production and are not the main content of this application. Therefore, they are only briefly described here and are not illustrated in the accompanying drawings.

[0046] The three-axis moving component 63 achieves movement on three vertical planes—X-axis, Y-axis, and Z-axis—by setting three sets of mutually perpendicular moving mechanisms, such as servo slides or linear guides. Its structure and working principle should be existing technology and well known to those skilled in the art, so they will not be described in detail here.

[0047] The feeding assembly 64 includes a set of connecting structures 641 and a plurality of sponge suction cups 642 disposed on the connecting structures 641. The connecting structures 641 are disposed on the three-axis moving assembly 63 and include a connecting plate and guide posts for mounting the sponge suction cups 642. The sponge suction cups 642 are disposed on the connecting structures 641, with one end connected to an air pump and the other end facing the product. After moving close to the product via the three-axis moving assembly 63, the product is fed by adsorbing it onto the feeding assembly 64. Using the sponge suction cups 642 effectively avoids damage to the product surface.

[0048] Compared with existing technologies, the diaphragm pump connecting rod shaft processing line provided by this utility model, through the setting of the feeding mechanism 10, quickly feeds products. Simultaneously, through the setting of the feeding rod 13, which is directly connected to the inside of the CNC lathe 20, the product feeding to the processing point of the CNC lathe 20 is fully automated without manual intervention. Furthermore, through the setting of the transfer mechanism 50, the products are sequentially moved from the CNC lathe 20 to the double-head processing equipment 30 and the centerless grinder 40 for processing. Simultaneously, through the setting of the rotating component 54 rotating the gripper component 56, the transfer mechanism 50 can move multiple sets of products at once, improving transfer efficiency and reducing the time and cost of equipment reciprocating motion. Finally, through the setting of the unloading mechanism 60, a suction cup is used to replace conventional robotic arms and grippers, effectively protecting the surface of the processed products from damage. This invention enables automated processing at each workstation, allowing products to flow automatically between workstations. This high efficiency effectively increases production capacity while minimizing manual intervention and saving labor costs. At the same time, it ensures product precision and yield, justifying the streamlined and intelligent production of diaphragm pump connecting rod shafts.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
