[0018] The following specifically describes the technical solution protected by the present invention in conjunction with the accompanying drawings
[0019] As Figure 1-2 shown, according to one aspect of the present application, a valve seat handling manipulator 1 is provided, which includes a clamping mechanism 110 and a robotic arm 120 that drives the multi-directional movement of the clamping mechanism 110. The clamping mechanism 110 includes a mounting substrate 11, a loading clamping module 12 and an unloading clamping module 13 provided on the mounting substrate 11. The loading clamping module 12 is movably connected to the mounting substrate 11 through a Z-direction floating mechanism 15, and is used to handle and place the valve seat to be processed in the machine tool material tray to realize the loading action; the unloading clamping module 13 is fixedly connected to the mounting substrate 11, and is used to take out the valve seat that has been processed in the machine tool material tray to realize the unloading action
[0020] As Figure 1-2 shown, each clamping module includes a number of clamping unit groups arranged at equal intervals along the X-axis. Each group includes a number of clamping components 121 distributed at equal intervals along the Y-axis. The clamping components 121 are used to clamp the valve seat. The loading clamping module 12 further includes an angle compensation member 14. The angle compensation member 14 is connected to the clamping components 121 in the same group and drives them to rotate horizontally synchronously, so as to realize that the clamping components 121 drive the valve seat to rotate synchronously, and place the valve seat according to the angle defined by the loading position of the machine tool material tray
[0021] In this embodiment, the loading clamping module 12 and the unloading clamping module 13 are arranged in parallel along the X-axis direction. The arrangement intervals and quantities of the clamping components 121 in each clamping module are the same as those of the loading positions of the machine tool material tray, and multiple valve seats can be loaded and unloaded at one time. After the clamping components 121 unload the valve seat, the loading of another group of valve seats can be realized, effectively improving the working efficiency
[0022] As Figure 2-5As shown, the clamping assembly 121 includes an XY-direction floating adjustment module 1212, a pneumatic gripper 1211, and a profiling clamping head 1213. The profiling clamping head 1213 is configured at the output end of the pneumatic gripper 1211, and the pneumatic gripper 1211 drives the profiling clamping head 1213 to complete the clamping and loosening actions; the pneumatic gripper 1211 is configured on the moving end of the XY-direction floating adjustment module 1212 to achieve the adjustment of the micro-displacement of the profiling clamping head 1213 in the X and Y directions within the plane, compensating for the plane positioning deviation. In a specific embodiment, the XY-direction floating adjustment module 1212 is composed of a crossed roller guide and an elastic element, which belongs to the existing publicly disclosed conventional technology in the technical field, and its specific structure will not be elaborated here.
[0023] As Figure 4-5 shown, wherein, in this embodiment, a stepped limit structure is provided on the inner side of the clamping end of the profiling clamping head 1213, which includes a supporting flange 12131 for supporting the step surface of the valve seat, a limiting flange 12132 for pressing against the upper end surface of the valve seat, and a profile matching groove 12133 formed between the two. When the profiling clamping head 1213 clamps the valve seat, the supporting flange 12131 correspondingly supports at the bottom of the step surface of the valve seat, and the stepped side end surface is appropriately arranged in the profile matching groove 12133.
[0024] As Figure 2-3 shown, the angle compensation member 14 includes a transmission link 141. The transmission link 141 has a first end and a second end that are axially opposite. The first end is fixedly connected to the clamping assembly 121, and the second end has an adjustment hole 1411 that penetrates in the Z direction. The adjustment hole 1411 is an elongated hole with a long axis, and a transmission main shaft 142 is inserted therein. The transmission main shaft 142 is connected to a displacement adjustment module.
[0025] As Figure 2-3 shown, the displacement adjustment module includes a Y-axis guiding slide rail 143, a guiding slide block 144, and a transverse moving cylinder 145. The Y-axis guiding slide rail 143 is fixed on the mounting substrate 11 and is parallel to the X-direction horizontal side of the clamping unit group. The guiding slide block 144 is slidably arranged on the Y-axis guiding slide rail 143, and the transverse moving cylinder 145 drives the guiding slide block 144 to reciprocate. The transmission main shaft 142 is fixedly connected to the guiding slide block 144. By driving the guiding slide block 144 to slide with the transverse moving cylinder 145, the transmission main shaft 142 connected to the guiding slide block 144 is displaced, driving the second end of the transmission link 141 to swing, and the transmission link 141 drives the clamping assembly 121 to rotate horizontally. A plurality of transmission main shafts 142 in the same displacement adjustment module are fixedly arranged on the same guiding slide block 144 to achieve the synchronous swing of multiple transmission links 141, that is, the synchronous rotation of multiple clamping assemblies 121 in the same clamping unit group. Preferably, the long axis extension direction of the adjustment hole 1411 forms an angle of 10° - 45° with the axis of the transmission link 141, so that the transmission main shaft 142 can be displaced along the adjustment hole 1411.
[0026] Preferably, in one embodiment, a set of displacement adjustment modules can be shared between two adjacent sets of clamping unit groups. The displacement adjustment module is placed between the two sets of clamping unit groups and drives multiple drive spindles in the two sets of clamping unit groups on both sides to move synchronously, so that the two sets of clamping unit groups on both sides can be synchronously adjusted in angle. This can reduce the driving elements required in the equipment, lower costs, save the structural occupied space, and improve the space utilization rate. Further, there are two sets of clamping components 121 arranged oppositely along the X direction in the two adjacent sets of clamping unit groups. The second ends of the two drive linkages 141 on the two sets of clamping components 121 can share one drive spindle 142, and the two drive linkages 142 are arranged offset in the Z-axis direction, so that one drive spindle 142 can pass through two adjustment holes in sequence, effectively improving the space utilization rate in the horizontal direction and avoiding mutual interference.
[0027] As Figure 2-3 shown, in this embodiment, the loading clamping module 12 includes two sets of clamping unit groups arranged at equal intervals along the X axis and a set of displacement adjustment modules placed between the two sets of clamping unit groups. The clamping components 121 in the two sets of clamping unit groups are symmetrically arranged along the X direction. Drive linkages 141 are respectively connected to the symmetric clamping components 121 on both sides. The two drive linkages 141 are arranged offset in the Z direction. The second ends of the two sets of drive linkages 141 pass through the same drive spindle 142, and the drive spindle 142 is fixed on the guide slide 144. In this embodiment, each drive spindle 142 is respectively configured with a corresponding guide slide 144. Multiple guide slides 144 are all slidably arranged on the Y-axis guide rail 143 and are sequentially connected in series through a linkage plate 146. The traverse cylinder 145 correspondingly drives the linkage plate 146 to reciprocate along the Y-axis direction, so that multiple guide slides 144 can slide synchronously. Further, in this embodiment, side end plates 111 are arranged on both sides of the mounting substrate 11 along the Y-axis direction. The cylinder body of the traverse cylinder 145 is fixedly arranged on the linkage plate 146, and the end of the push rod of the traverse cylinder 145 is fixed on the side end plate 111. The traverse cylinder 145 drives the push rod to extend and retract. The end of the push rod is fixed on the side end plate 111 and remains stationary, and the reverse action pushes the cylinder body to move, thereby correspondingly driving the linkage plate 146 to move.
[0028] During the loading process, the loading clamping module 12 drives the valve seat to be placed at the machine tool unloading position, and drives multiple sets of clamping components 121 to rotate synchronously through the angle compensation member 14. During the rotation of the valve seat, there is a position angle such that the gap between the valve seat pins is adapted to the positioning boss at the machine tool unloading position. After the valve seat is clamped and placed in the unloading position, the profiling clamping head of the clamping component no longer drives the valve seat to rotate.
[0029] As Figure 2-3As shown in the figure, the Z-direction floating mechanism 15 includes a linear bearing 151 provided on the mounting substrate 11. A Z-direction floating guide rod 152 is slidably arranged in the linear bearing 151, so that the Z-direction floating guide rod 152 can move axially and rotate circumferentially along the linear bearing 151. The lower end of the Z-direction floating guide rod 152 is connected to the clamping assembly 121. A reference plate 154 is arranged at the upper end of the Z-direction floating guide rod 152, and the upper end of the Z-direction floating guide rod 152 movably penetrates through the reference plate 154. A floating spring 153 is sleeved on the circumference of the Z-direction floating guide rod 152, with one end abutting against the reference plate 154 and the other end acting on the linear bearing 151.
[0030] As Figure 3 shown, preferably, a position detection sensor 155 is arranged on the reference plate 154 for detecting the position of the end of the Z-direction floating guide rod 152. Once the valve seat is not placed in place, the lower end of the valve seat abuts against the convex platform at the feeding position, the floating spring 153 is compressed, the Z-direction floating guide rod 152 floats upward, and when the position detection sensor 155 detects the end of the Z-direction floating guide rod 152, a prompt alarm is issued, and the angle compensation member 14 acts, and the clamping assembly 121 rotates horizontally until all the valve seats fall into the feeding position, that is, the feeding of the valve seats is completed.
[0031] In a specific embodiment, the position detection sensor 155 is a photoelectric sensor or a proximity switch, and its detection surface faces the upper end surface of the Z-direction floating guide rod 152, and an alarm signal is generated when detecting the displacement of the end of the guide rod.
[0032] As Figure 6 shown, according to another aspect of the present application, a valve seat feeding device is provided, which includes a feeding module 2, a temporary storage module 3, a transfer module 4 and the above-mentioned valve seat handling manipulator 1. The feeding module 2 is used for continuously feeding the valve seats. The transfer module 4 sequentially transports and transfers the valve seats to the temporary storage module 3, and then the feeding clamping module 12 of the valve seat handling manipulator 1 clamps multiple valve seats at a time and synchronously transports them to the processing machine tool. The discharging clamping module 13 of the handling manipulator 1 first takes out the valve seats that have been processed in the machine tool, and then places the valve seats clamped by the feeding clamping module 12 into the machine tool, effectively improving the working efficiency.
[0033] As Figure 6 shown, the feeding module 2 includes a vibrating bowl 21, a straight material channel 22 connected to the discharging end of the vibrating bowl 21, and a material dividing member 23 arranged at the discharging end of the straight material channel 22. A linear vibrator is provided below the straight material channel 22, and the valve seats in the straight material channel 22 are vibrated and conveyed to the material dividing member 23 through the linear vibrator.
[0034] As Figure 6-7As shown in the figure, the material distributing member 23 includes a material distributing support 231, on which a rotatable turntable 232 and a rotary driving member 233 for driving the horizontal rotation of the turntable 232 are provided. The material distributing support 231 has a transition channel 235 communicating with the straight material channel 22. At least two spaced notches 234 are formed at the edge of the turntable 232, and the size of the notch 234 is defined to accommodate only a single valve seat. In the rotation path of the turntable 232, the notch 234 can communicate with the transition channel 235 to receive the valve seats vibrationally conveyed from the straight material channel 22. A sensor (not labeled) is provided on the side of the notch 234 to detect whether there is a valve seat in the notch 234. Once it is detected that the valve seat is in place, the rotary driving member 233 drives the turntable 232 to rotate, so that the notch 234 is misaligned with the transition channel 235, realizing the material distribution of the valve seats.
[0035] As Figure 7 shown, further, a clamping strip 236 is provided in the straight material channel 22, and the clamping strip 236 extends into the transition channel 235. The width of the clamping strip 236 is smaller than the pin gap of the valve seat, which is used to preliminarily define the discharging direction of the valve seat and prevent hard contact between the clamping strip 236 and the valve seat pins, causing damage to the valve seat. A clamping block 237 adapted to the clamping strip 236 is provided in the notch 234 of the turntable 232. When the notch 234 corresponds to and communicates with the transition channel 235, the clamping block 237 is located in the extending direction of the clamping strip 236, so that the valve seat enters the notch 234 at an angle defined by the clamping strip 236.
[0036] As Figure 8 shown, the temporary storage module 3 includes a temporarily stored placement plate 31 that can rotate around an axis and a rotary driving module 34 for driving the rotation of the temporarily stored placement plate. Two groups of temporarily stored material plates 32 are symmetrically arranged on the temporarily stored placement plate 31, and a number of temporarily stored positions 33 adapted to the shape of the valve seat are arranged on the temporarily stored material plates 32. The arrangement order and quantity of the temporarily stored positions 33 correspond to the feeding positions on the subsequent processing machine tool. Preferably, positioning bosses adapted to the pin spacing of the valve seat are arranged in the temporarily stored positions 33 to define the placement angle of the valve seat.
[0037] The transfer module 4 is arranged between the material distributing member 23 and the temporary storage module 3, and is used to transfer the valve seats output by the material distributing member 23 to the temporarily stored positions 33 of a temporarily stored material plate one by one. Preferably, the transfer module 4 includes a material taking gripper and a moving driving module for driving the material taking gripper between the material distributing member 23 and the temporary storage module 3. In a specific embodiment, the moving driving module can be a robotic arm or a fast handling mechanism, and its specific structure is not limited herein.
[0038] After the temporary storage position 33 of the temporary storage plate is filled, the rotation drive module 34 drives the temporary storage and placement plate 31 to rotate. The loading clamping module 12 of the handling manipulator 1 is used to synchronously transfer a plurality of valve seats on the above-mentioned temporary storage plate 32 to the corresponding discharging positions of the processing machine tool. At the same time, the transfer module 4 performs individual feeding of valve seats to the temporary storage positions of another temporary storage plate. The temporary storage, feeding, and discharging of valve seats on the two groups of temporary storage plates are carried out simultaneously, effectively improving the working efficiency and accelerating the working rhythm.
[0039] In this embodiment, the rotation drive member and the rotation drive module can be selected from structures such as a stepping motor, a servo motor, and a reducer, and no specific limitation is made here.
[0040] Working principle: The vibrating disk 21 vibrates for feeding. The straight material channel 22 guides the valve seats to the notch 234 of the material distributing member 23. The turntable 232 rotates to displace the notch 234 from the straight material channel 22. The transfer module 4 transfers and transports the valve seats discharged from the material distribution one by one to the temporary storage position 33 of the temporary storage plate 32. After the temporary storage plate 32 is filled, the temporary storage and placement plate 31 rotates, and another temporary storage plate 32 continues to receive the materials. The valve seat handling manipulator 1 synchronously grabs and transfers the valve seats on the full temporary storage plate to the machine tool.
[0041] The unloading clamping module 13 first takes out the valve seats in the discharging position of the machine tool. The loading clamping module 12 clamps the valve seats and moves them above the discharging position, and places the valve seats in the discharging position. The XY-direction floating adjustment module 1212 can adaptively adjust the horizontal placement position of the valve seats. Since the discharging angle of the valve seats does not match the discharging position, the pins of the valve seats correspondingly abut against the convex platforms in the discharging position, and the entire clamping assembly 121 floats upward along the Z direction to avoid damage to the pins of the valve seats. The angle compensation member 14 drives the clamping assembly 121 to rotate horizontally synchronously. During the rotation, the valve seats rotate to a position point where the pin gaps of the valve seats match the convex platforms. The clamping assembly 121 drives the valve seats to fall downward into the discharging position. The angle adjustment member continues to drive the clamping assembly to rotate to complete the slipping between the adapted valve seats and the clamping assembly and stop rotating. The unadapted valve seats continue to rotate synchronously until all the valve seats fall into the discharging position, thereby completing the feeding of the valve seats.
