Description

Technical Field

[0001] This utility model belongs to the field of plunger pump assembly technology, and in particular relates to a plunger spring feeding mechanism. Background Technology

[0002] Currently, piston pumps are key actuators in hydraulic systems, and their performance stability directly affects the overall efficiency and reliability of the hydraulic system. As one of the core components of a piston pump, the piston spring primarily undertakes important functions such as providing return force, ensuring a tight fit between the piston and the slipper, damping vibrations, and maintaining smooth operation. The quality and precision of the spring assembly directly determine the piston pump's lifespan, noise level, and overall performance.

[0003] In the spring assembly process of plunger pumps, most manufacturers still rely primarily on manual operation, or supplemented by a simple combination of vibratory feeders and pneumatic robots for semi-automatic feeding. This manual method is not only inefficient and labor-intensive, but also prone to spring omissions, reverse installations, or deformation and damage due to operator fatigue and individual differences, making it difficult to guarantee consistency and reliability. While existing semi-automatic equipment alleviates the burden of manpower to some extent, it still generally suffers from poor material distribution stability, low positioning accuracy, and low spring posture consistency.

[0004] To solve the above-mentioned technical problems, this utility model designs a plunger spring feeding mechanism. Utility Model Content

[0005] This utility model provides a plunger spring feeding mechanism, which aims to solve the problem of how to improve the feeding efficiency and feeding accuracy of plunger springs in plunger pumps.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plunger spring feeding mechanism, comprising a distributing mechanism and a gripping mechanism. The distributing mechanism includes a vibratory feeder, a distributing assembly, and a rotary positioning assembly. The vibratory feeder and the distributing assembly are connected via a transport pipe. The rotary positioning assembly includes a rotating seat and a fixed seat surrounding the rotating seat. The rotating seat is rotatable relative to the fixed seat. Multiple plunger spring placement slots are evenly distributed around the rotating seat. The fixed seat has a feed inlet. The distributing assembly has a push plate corresponding to the feed inlet. The push plate is movable in a direction close to or away from the feed inlet to push the plunger spring from the feed inlet into the plunger spring placement slot. The gripping mechanism is used to move the plunger springs in the multiple plunger spring placement slots to the plunger seat to be assembled.

[0007] Based on the above technical solution, the material distribution assembly includes a material distribution seat, a first cylinder, and a second cylinder. The material distribution seat has a material distribution channel inside. The top end of the material distribution channel is connected to the transport pipe, and the bottom end of the material distribution channel has a discharge port. The discharge port is correspondingly arranged with the inlet. The first cylinder and the second cylinder are sequentially inserted into the side wall of the material distribution seat in the vertical direction. Both the first cylinder and the second cylinder can move in the direction perpendicular to the extension of the material distribution channel.

[0008] Furthermore, the plunger seat is provided with multiple mounting holes, the distribution of which corresponds to the distribution of multiple plunger spring placement slots.

[0009] Based on the above technical solution, the material distribution assembly further includes a third cylinder, which is located on one side of the material distribution seat and passes through the side wall of the material distribution seat. A push rod is connected to the end of the third cylinder.

[0010] Furthermore, the rotary positioning assembly also includes a first sensor, which is disposed through the side wall of the fixed base, with the end of the first sensor facing the plunger spring placement groove.

[0011] Based on the above technical solution, the rotary positioning assembly further includes a drive motor, which is connected to the rotary seat to drive the rotary seat to rotate. Based on the above technical solution, the gripping mechanism includes a horizontal drive mechanism, a vertical drive mechanism, and a gripping member. The vertical drive mechanism is located within the horizontal drive mechanism, and the gripping member is located within the vertical drive mechanism. The gripping member is correspondingly positioned to correspond with the rotary positioning assembly.

[0012] Furthermore, the gripping component includes a fixing part and an airbag part. The airbag part is located at the center of the fixing part. The fixing part is provided with multiple gripping grooves. The airbag part can expand or contract in the direction of approaching or moving away from the multiple gripping grooves to grip and release multiple plunger springs.

[0013] Based on the above technical solution, the plunger spring feeding mechanism also includes a guide mechanism, which is located above the plunger seat and has multiple guide holes, the distribution of which corresponds to the distribution of multiple mounting holes.

[0014] Furthermore, the guiding mechanism includes multiple adjustable support legs and a guide plate, with the multiple adjustable support legs supported on the guide plate and multiple guide holes provided on the guide plate.

[0015] Compared with related technologies, the beneficial effects of this utility model are as follows: In this invention, the plunger spring is fed into the material distribution assembly via a conveying pipe from a vibratory plate. After being distributed by the material distribution assembly, the pusher plate moves along the direction close to the feed inlet, pushing the plunger spring into the plunger spring placement slot of the rotating seat. The rotating seat rotates relative to the fixed seat until the next plunger spring placement slot corresponds to the feed inlet. The pusher plate pushes the next plunger spring into the plunger spring placement slot until all the plunger spring placement slots in the rotating seat are filled. The gripping mechanism then moves the multiple plunger springs into the plunger seat to be assembled.

[0016] By combining a vibratory feeder with a material distribution assembly, the automatic sorting and conveying of plunger springs is achieved, avoiding the chaos and errors that may occur in traditional manual operations. The design of the rotary positioning assembly allows the plunger springs to be placed and gripped in precise positions, thereby improving the overall assembly accuracy. The flexibility and efficiency of the gripping mechanism further optimize the feeding process. This plunger spring feeding mechanism can effectively improve the feeding efficiency of plunger springs, reduce manual intervention, and ensure the stability and consistency of the assembly process.

[0023] Combination Figure 1 and Figure 2 As shown, this embodiment of the disclosure provides a plunger spring feeding mechanism, including a material distribution mechanism 21 and a gripping mechanism 22. The material distribution mechanism 21 includes a vibratory feeder 211, a material distribution assembly 212, and a rotary positioning assembly 213. The vibratory feeder 211 and the material distribution assembly 212 are connected by a transport pipe 214. The rotary positioning assembly 213 includes a rotating seat 2131 and a fixed seat 2132 surrounding the rotating seat 2131. The rotating seat 2131 is rotatable relative to the fixed seat 2132. Multiple plunger spring placement slots 2133 are evenly distributed around the periphery of the 131. The fixed seat 2132 is provided with a feed inlet 2134. The material distribution component 212 is provided with a push plate 2121 corresponding to the feed inlet 2134. The push plate 2121 can move in a direction close to or away from the feed inlet 2134 to push the plunger spring from the feed inlet 2134 into the plunger spring placement slot 2133. The gripping mechanism 22 is used to move the plunger springs in the multiple plunger spring placement slots 2133 to the plunger seat to be assembled.

[0024] Using the plunger spring feeding mechanism provided in this embodiment, the plunger springs are fed into the material distribution assembly 212 via the conveying pipe 214 from the vibrating plate 211. After being distributed by the material distribution assembly 212, the push plate 2121 moves along the direction close to the feed port 2134, pushing the plunger springs into the plunger spring placement slot 2133 of the rotating seat 2131. The rotating seat 2131 rotates relative to the fixed seat 2132 until the next plunger spring placement slot 2133 corresponds to the feed port 2134. The push plate 2121 pushes the next plunger spring into the plunger spring placement slot 2133 until all the plunger spring placement slots 2133 in the rotating seat 2131 are filled. The gripping mechanism 22 moves the multiple plunger springs into the plunger seat to be assembled.

[0025] The automatic sorting and conveying of plunger springs is achieved through the cooperation of the vibratory feeder 211 and the material distribution component 212, avoiding the chaos and errors that may occur in traditional manual operations. The design of the rotary positioning component 213 allows the plunger springs to be placed and grasped in precise positions, thereby improving the overall assembly accuracy. The flexibility and efficiency of the grasping mechanism 22 further optimize the feeding process. This plunger spring feeding mechanism can effectively improve the feeding efficiency of plunger springs, reduce manual intervention, and ensure the stability and consistency of the assembly process.

[0026] Based on the above technical solutions, such as Figure 2 and Figure 5-6 As shown, the material distribution assembly 212 includes a material distribution seat 2122, a first cylinder 2123, and a second cylinder 2124. The material distribution seat 2122 has a material distribution channel 2125 inside. The top end of the material distribution channel 2125 is connected to the transport pipe 214, and the bottom end of the material distribution channel 2125 has a discharge port 2126. The discharge port 2126 is correspondingly arranged with the inlet port 2134. The first cylinder 2123 and the second cylinder 2124 are sequentially inserted into the side wall of the material distribution seat 2122 in the vertical direction. Both the first cylinder 2123 and the second cylinder 2124 can move in a direction perpendicular to the extension of the material distribution channel 2125.

[0027] Furthermore, the free height of the plunger spring is Hf, and the height between the first cylinder 2123 and the second cylinder 2124 is H, where Hf < H < 2Hf.

[0028] like Figure 6As shown, when multiple plunger springs enter the distribution channel 2125 from the vibratory plate 211 through the transport pipe 214, the initial state of the first cylinder 2123 is that it extends to the inner wall of the distribution channel 2125 to block all the plunger springs falling into the distribution channel 2125. When the plunger springs fall to contact the extended first cylinder 2123, the second cylinder 2124 extends. When the height H between the first cylinder 2123 and the second cylinder 2124 is in the range of Hf < H < 2Hf, the second cylinder 2124 extends. When cylinder 24 extends, it presses down on the second plunger spring counted from bottom to top. Cylinder 2123 retracts, and the first plunger spring counted from bottom to top, which is also the lowest plunger spring, falls to the bottom of the distribution seat 2122. Push plate 2121 is located on the side of the plunger spring away from the discharge port 2126. Push plate 2121 moves in the direction close to the discharge port 2126, pushing the plunger spring out of the discharge port 2126 and into the corresponding plunger spring placement slot 2133 through the feed port 2134. Push plate 2121 retracts. At this time, cylinder 2123 extends, cylinder 2124 retracts, and the plunger spring falls to cylinder 2123. Cylinder 2124 extends, pressing down on the plunger spring at the corresponding height. Cylinder 2123 retracts, and the lowest plunger spring falls. Push plate 2121 pushes it into the plunger spring placement slot 2133. This process is repeated to complete the distribution of subsequent plunger springs.

[0029] Optionally, there are multiple material distribution components 212, which can simultaneously distribute multiple sets of plunger springs.

[0030] Optionally, the vibratory feeder 211 is provided with a spirally ascending guide rail, the end of which is connected to the transport pipe 214 for orderly conveying the plunger gaskets to the push rod 2128 assembly. This design not only enables automatic sorting of the plunger springs but also avoids conveying failures caused by accumulation or jamming.

[0031] Furthermore, the plunger seat is provided with multiple mounting holes, the distribution of which corresponds to the distribution of multiple plunger spring placement slots 2133.

[0032] Once the multiple plunger spring placement slots 2133 in the rotating seat 2131 are full, the gripping mechanism 22 grips multiple plunger springs and moves them simultaneously into the plunger seat, ensuring that each plunger spring falls precisely into the corresponding mounting hole, thereby achieving efficient and accurate assembly operations.

[0033] Based on the above technical solutions, such as Figure 2 and Figure 7 As shown, the material distribution assembly 212 also includes a third cylinder 2127, which is located on one side of the material distribution seat 2122 and passes through the side wall of the material distribution seat 2122. A push rod 2128 is connected to the end of the third cylinder 2127.

[0034] Furthermore, the height HT at the end of the push rod 2128 is higher than the height H1 of the first cylinder 2123, and the height HT at the end of the push rod 2128 is less than H1 + Hf.

[0035] When multiple plunger springs enter the material distribution channel 2125, the first cylinder 2123 extends to block them, and the second cylinder 2124 extends to press down the plunger spring at the corresponding height. The first cylinder 2123 retracts. At this point, it is expected that the lowest plunger spring will fall to the bottom of the material distribution seat 2122. If the lowest plunger spring gets stuck with the plunger spring above it, the third cylinder 2127 drives the push rod 2128 to push the lowest plunger spring down, ensuring the smooth progress of the material distribution process. The height HT of the end of the push rod 2128 is designed to be higher than the height H1 of the first cylinder 2123, but lower than the sum of H1 and the free height Hf of the plunger spring. This setting can effectively avoid interference with the upper plunger spring, while ensuring that the push rod 2128 can accurately act on the lowest plunger spring. Through the auxiliary action of the third cylinder 2127, the reliability and efficiency of material distribution are further improved, and the risk of equipment downtime or failure due to spring jamming is reduced.

[0036] In addition, the material distribution assembly 212 has a compact overall structure, and the cooperation between each cylinder can quickly complete a material distribution operation. This efficient material distribution method not only improves the feeding efficiency, but also reduces the possibility of damage to the plunger spring during the conveying process, thereby ensuring the stability of product quality.

[0037] The push plate 2121 is provided with a fourth cylinder 2129, which is connected to the push plate 2121 and is used to drive the push plate 2121 to move in a direction close to the fixed seat 2132.

[0038] Furthermore, such as Figure 2 As shown, the rotary positioning assembly 213 also includes a first sensor 2135, which is disposed through the side wall of the fixed base 2132, and the end of the first sensor 2135 is disposed toward the plunger spring placement groove 2133.

[0039] After a spring is placed in the plunger spring placement slot 2133, the rotating seat 2131 rotates relative to the fixed seat 2132, rotating the plunger spring placement slot 2133 to correspond with the first sensor 2135. The first sensor 2135 detects whether there is a spring in the plunger spring placement slot 2133. If a spring is detected in the plunger spring placement slot 2133, the material distribution process continues to the next plunger spring placement slot 2133. If no spring is detected, the first sensor 2135 sends a signal, the rotating seat 2131 rotates back, and the material distribution component 212 re-performs the material distribution operation, ensuring that a plunger spring can be accurately placed in each plunger spring placement slot 2133, further improving the reliability and accuracy of the entire material feeding process.

[0040] Based on the above technical solutions, such as Figure 2 As shown, the rotary positioning assembly 213 also includes a drive motor 2136, which is connected to the rotary seat 2131 to drive the rotary seat 2131 to rotate.

[0041] In this embodiment, as Figure 2 As shown, the material distribution mechanism 21 also includes a base 215, which is provided with a fixed platform 216. The material distribution component 212 and the rotary positioning component 213 are fixed on the fixed platform 216. Specifically, the material distribution seat 2122 is provided on the fixed platform 216, the fixed seat 2132 is provided on the fixed platform 216, the rotary motor is provided below the fixed platform 216, and the rotary motor is fixed to a fixed plate 2161. The fixed plate 2161 is connected to the fixed platform 216 through multiple connecting legs 2162. The rotary seat 2131 is provided with a rotary shaft 2163, and the drive motor 2136 is connected to the rotary shaft 2163 through a coupling 2164.

[0042] Furthermore, such as Figure 3 and Figure 4 As shown, the rotating shaft 2163 is provided with an extension plate 2165, and the rotating positioning assembly 213 also includes a second sensor 2166. The second sensor 2166 is provided with a detection groove, which is set towards the extension plate 2165. The second sensor 2166 is used to detect whether the rotating seat 2131 has rotated one revolution. When the extension plate 2165 rotates with the rotating shaft 2163, it starts to pass through the detection groove for the first time. It continues to rotate until it passes through the detection groove for the second time, indicating that the rotating seat 2131 has completed one revolution and the multiple plunger spring placement slots 2133 of the rotating seat 2131 have been placed.

[0043] Optionally, there may be multiple rotary positioning components 213, which cooperate with multiple material dispensing components 212.

[0044] Based on the above technical solutions, such as Figure 8 As shown, the gripping mechanism 22 includes a horizontal drive mechanism 221, a vertical drive mechanism 222, and a gripping member 223. The vertical drive mechanism 222 is disposed on the horizontal drive mechanism 221, and the gripping member 223 is disposed on the vertical drive mechanism 222. The gripping member 223 is correspondingly disposed with the rotary positioning component 213.

[0045] Specifically, the horizontal drive mechanism 221 drives the vertical drive mechanism 222 and the gripper 223 to move horizontally, enabling the gripper 223 to switch positions between the rotary positioning assembly 213 and the plunger seat. The vertical drive mechanism 222 controls the lifting and lowering of the gripper 223. The horizontal drive mechanism 221 and the vertical drive mechanism 222 work together to ensure that the gripper 223 can accurately remove the plunger spring from the plunger spring placement slot 2133 on the rotary seat 2131 and place it into the mounting hole of the plunger seat. Both the horizontal drive mechanism 221 and the vertical drive mechanism 222 are driven by high-precision servo motors in conjunction with slide rails to ensure stability and positioning accuracy during the gripping process. Through the coordinated work of the horizontal drive mechanism 221, the vertical drive mechanism 222, and the gripper 223, the gripping mechanism 22 can efficiently complete the synchronous transfer of multiple plunger springs, significantly improving the overall feeding efficiency.

[0046] Furthermore, such as Figure 9 As shown, the gripper 223 includes a fixing part 2231 and an airbag part 2232. The airbag part 2232 is located at the center of the fixing part 2231. The fixing part 2231 is provided with a plurality of gripping grooves 2233. The airbag part 2232 can expand or shrink in the direction of approaching or moving away from the plurality of gripping grooves 2233 in order to grip and release a plurality of plunger springs.

[0047] Specifically, the vertical drive mechanism 222 is provided with a fixing plate 2161, the fixing part 2231 is fixed to the fixing plate 2161, the fixing part 2231 of the gripping member 223 is arranged opposite to the fixing seat 2132 of the rotary positioning assembly 213, and the distribution positions of the multiple gripping slots 2233 correspond to the distribution positions of the multiple plunger spring placement slots 2133.

[0048] When the airbag 2232 is in an uninflated state, the gripping slot 2233 remains open, facilitating the entry and exit of the plunger springs. During the gripping process, the horizontal drive mechanism 221 adjusts the gripper 223 to move above the plunger spring placement slot 2133 of the rotating seat 2131, aligning the plunger spring placement slot 2133 with the gripping slot 2233. The vertical drive mechanism 222 lowers the gripper 223 until the top portion of the plunger spring enters the gripping slot 2233, and the airbag 2232 begins to inflate, applying pressure to multiple gripping slots 2233, thereby firmly securing multiple plunger springs. After the gripping is complete, the vertical drive mechanism 222 lifts the gripper 223, and the horizontal drive mechanism 221 moves it above the mounting hole of the plunger seat. The vertical drive mechanism 222 then descends, the airbag 2232 deflates and shrinks, releasing the plunger springs so that they accurately fall into the corresponding mounting holes. Through the elastic deformation of the air bladder 2232 and the controllable pressure adjustment, this design effectively avoids damage to the surface of the plunger spring while ensuring stability during gripping and placement. Furthermore, the structural design of the gripper 223 enables the simultaneous gripping of multiple plunger springs in a single operation, further improving assembly efficiency and precision.

[0049] Optionally, there are multiple gripping members 223, which cooperate with multiple rotary positioning components 213 to simultaneously grip multiple sets of plunger springs.

[0050] Based on the above technical solutions, such as Figure 10 As shown, the plunger spring feeding mechanism also includes a guide mechanism 23, which is located above the plunger seat. The guide mechanism 23 has multiple guide holes 231, and the distribution positions of the multiple guide holes 231 correspond to the distribution positions of the multiple mounting holes.

[0051] The guide mechanism 23 is designed to effectively guide the plunger spring to accurately fall into the mounting hole of the plunger seat, avoiding assembly failure or damage due to positional deviation. Specifically, the inner diameter of the guide hole 231 is slightly larger than the outer diameter of the plunger spring, forming a certain clearance fit to ensure that the plunger spring is properly constrained and guided during its descent. By setting up the guide mechanism 23, the stability and reliability of the entire feeding process are further improved, while reducing the need for manual intervention and significantly improving assembly efficiency and product quality consistency.

[0052] Furthermore, such as Figure 10 As shown, the guiding mechanism 23 includes multiple adjustable support legs 232 and a guide plate 233. The multiple adjustable support legs 232 are supported on the guide plate 233, and multiple guide holes 231 are provided on the guide plate 233.

[0053] The adjustable support legs 232 allow the guide plate 233 to be flexibly adjusted in height and angle according to actual needs, thus adapting to plunger seats of different sizes and specifications. Adjusting the support legs ensures that the guide hole 231 and the mounting hole of the plunger seat remain precisely aligned, further improving the accuracy and adaptability of the assembly process. The adjustable support legs 232 also enhance the equipment's versatility, enabling quick switching to different production tasks without the need for additional replacement of the guide mechanism 23, thereby reducing production costs and improving work efficiency. In actual operation, the adjustment device of the guide mechanism 23 is equipped with a locking function to ensure secure fixation after adjustment, preventing positional displacement due to vibration or external forces, further guaranteeing the stability and reliability of the feeding process.

[0054] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
