Description

Technical Field

[0001] This utility model belongs to the field of compressor technology, specifically relating to a compressor rotor pump gripper mechanism. Background Technology

[0002] Currently, during the process of transporting the compressor from the rotor cooling furnace to the main line, the rotor and pump are connected together by a shaft. To prevent relative rotation of the rotor and pump during transport, the industry uses a dual-cylinder power source to unload the rotor and pump. The dual-cylinder power source includes a gripper cylinder and a lifting cylinder. The gripper cylinder is used to hold the rotor, and the lifting cylinder is used to drive the positioning shaft to extend and position it in the positioning hole on the cylinder body, so that the rotor and pump will not be displaced relative to each other.

[0003] However, in practical applications, it has been found that when the lifting cylinder drives the positioning shaft to extend, it is easy to cause oblique insertion, which cannot ensure the stability of the rotor pump. In addition, the whole process requires two power sources to drive it, resulting in a large power source loss. Summary of the Invention

[0004] To address the shortcomings of the prior art, this utility model provides a compressor rotor pump gripper mechanism that can stably clamp and position the connected rotor and pump using only one power source, preventing relative displacement between the rotor and pump. This reduces power source losses and improves operational stability.

[0005] The technical effects to be achieved by this utility model are realized through the following technical aspects: This utility model provides a compressor rotor pump gripper mechanism for clamping and positioning the rotor and the pump. The gripper mechanism includes a first mounting plate, a gripper cylinder, multiple gripper assemblies, and multiple clamping assemblies. The gripper cylinder is mounted on the first mounting plate, and the plurality of gripper assemblies are connected to the drive end of the gripper cylinder; The gripper cylinder is provided with a second mounting plate, and a plurality of the clamping components are connected to the second mounting plate at intervals; The first mounting plate is used to connect to an external power source. Under the action of the external power source, the first mounting plate drives the gripper cylinder to move to the upper end of the rotor and presses the clamping assembly against the upper end face of the pump. The gripper cylinder drives multiple gripper assemblies to clamp the rotor.

[0006] In some implementations, the gripper assembly includes a gripper body and a clamping block; The mounting end of the gripper body is connected to the driving end of the gripper cylinder, and the clamping end of the gripper body is connected to the clamping block. The clamping block has a first contour groove that is adapted to the clamping position on the rotor. The first contour groove can improve the clamping fit of the rotor and ensure the stability of the rotor pumping and transporting process.

[0007] In some implementations, the first contouring groove is an arc-shaped groove whose shape is adapted to the curvature of the rotor side.

[0008] In some implementations, the clamping block is a silicone clamping block. The silicone clamping block can avoid hard contact with the outer peripheral surface of the rotor, thus preventing damage to the rotor surface and ensuring product quality.

[0009] In some implementations, the clamping block has a second contoured groove formed on it for adapting to the clamping end of the gripper body; The clamping end of the gripper body is embedded in the second contour groove and is locked to the clamping block by screws to prevent positional movement between the clamping end of the gripper body and the clamping block during the clamping process, thus ensuring the connection stability between the clamping end of the gripper body and the clamping block.

[0010] In some implementations, the number of gripper assemblies is three, and the gripper cylinder is a three-grip cylinder. The three-grip cylinder drives the three gripper assemblies to clamp the rotor, ensuring the clamping force on the rotor.

[0011] In some implementations, the number of clamping components is three, and the three clamping components are distributed at intervals along the circumferential direction to achieve a uniform clamping effect on the upper end face of the pump.

[0012] In some implementations, each of the clamping components is located in the middle of two adjacent gripper components. The staggered arrangement of the clamping components and gripper components can not only avoid mutual interference, but also ensure uniform force distribution in different directions and improve handling stability.

[0013] In some implementations, the clamping assembly includes a limiting rod, a spring, and a clamping shaft; The spring is sleeved on the limiting rod, the upper end of the limiting rod is connected to the second mounting plate, and the lower end of the limiting rod is slidably connected to the pressing shaft. The two ends of the spring abut against the upper ends of the second mounting plate and the clamping shaft, respectively. The spring acts as a buffer, ensuring the clamping force of the clamping shaft on the upper surface of the pump while avoiding damage caused by hard contact.

[0014] In some implementations, the clamping shaft has a first through hole and a second through hole that are connected along the axial direction, and the diameter of the first through hole is smaller than the diameter of the second through hole; The lower end of the limiting rod passes through the first through hole, and the lower end of the limiting rod is connected to a limiting piece. The diameter of the limiting piece is larger than the diameter of the first through hole and smaller than the diameter of the second through hole.

[0015] In summary, this utility model has at least the following advantages: 1. The compressor rotor pump gripper mechanism provided by this utility model uses an external power source to drive the first mounting plate to move the gripper cylinder to the upper end of the rotor, while pressing the clamping component onto the upper end surface of the pump. This eliminates the need for a separate power source to drive the clamping component, thus reducing power source losses.

[0016] 2. The compressor rotor pump gripper mechanism provided by this utility model presses the rotor rotor on the upper surface of the pump through a clamping assembly, and at the same time, the gripper cylinder drives the gripper assembly to clamp the rotor, so that the rotor and the pump will not be displaced relative to each other, thereby improving the stability of operation.

The drawings illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] Example 1: Please see Figures 1-3 A compressor rotor pump gripper mechanism for clamping and positioning the rotor 700 and the pump 800, as known, such as Figure 2 As shown, during the process of transporting the compressor from the rotor cooling furnace to the main line, the rotor 700 and the pump 800 are connected together by a shaft. If they are not limited and fixed during the transport process, the relative displacement between the rotor 700 and the pump 800 will change based on the shaft. Therefore, the compressor rotor pump gripper mechanism provided in this embodiment is used to clamp and position the rotor and the pump. Specifically, it clamps the rotor 700 and presses the upper end face of the pump 800.

[0023] Specifically, the gripper mechanism includes a first mounting plate 100, a gripper cylinder 200, multiple gripper assemblies 300, and multiple clamping assemblies 400. The gripper cylinder 200 is mounted on the first mounting plate 100, and the multiple gripper assemblies 300 are connected to the drive end of the gripper cylinder 200. A second mounting plate 500 is mounted on the gripper cylinder 200, and the multiple clamping assemblies 400 are spaced apart and connected to the second mounting plate 500.

[0024] The first mounting plate 100 is used to connect to an external power source. Under the action of the external power source, the first mounting plate 100 drives the gripper cylinder 200 to move to the upper end of the rotor and causes the clamping assembly 400 to press against the upper end face of the pump. The gripper cylinder 200 drives multiple gripper assemblies 300 to clamp the rotor.

[0025] It should be noted that the gripper mechanism is used to clamp the rotor and press the pump. However, the overall positional movement of the gripper mechanism requires an external power source. For example, the first mounting plate 100 is connected to the drive end of the multi-axis robot. After the multi-axis robot drives the gripper mechanism to move above the rotor, the multi-axis robot continues to drive the gripper mechanism to move downward until the pressing component 400 presses against the upper surface of the pump. Then, the multi-axis robot stops working, the gripper cylinder 200 drives the gripper component 300 to clamp the rotor, and then the multi-axis robot drives the gripper mechanism to move the rotor pump, thereby realizing the transport of the rotor pump.

[0026] Understandably, a pump typically includes an upper support, a cylinder, and a lower support, which are connected sequentially from top to bottom. Therefore, the upper surface of the pump is the upper surface of the upper support.

[0027] In this embodiment, the external power source can also be a drive module that is used to realize lifting and lateral movement respectively. The drive module drives the gripper mechanism to perform lifting and lateral movement, thereby realizing the handling operation of the rotor pump.

[0028] In this embodiment, a single power source is sufficient to achieve stable clamping and positioning of the connected rotor and pump. This means that after the gripper mechanism moves to the set position under the action of an external power source, only one power source, namely the gripper cylinder 200, is needed to cooperate with the external power source to complete the transport operation of the rotor and pump. In other words, the pressing action on the upper surface of the pump is actually achieved by the pressing action of the external power source. In the traditional method, after the overall position of the gripper mechanism is moved by the external power source, an additional power source is still required to drive the extension of the positioning shaft.

[0029] This embodiment provides a compressor rotor pump gripper mechanism. By using an external power source to drive the first mounting plate 100 to move the gripper cylinder 200 to the upper end of the rotor, the clamping assembly 400 is pressed against the upper end surface of the pump. This eliminates the need for a separate power source to drive the clamping assembly 400, reducing power source losses. By pressing the clamping assembly 400 against the upper end surface of the pump, and simultaneously using the gripper cylinder 200 to drive the gripper assembly 300 to clamp the rotor, the rotor and pump will not experience relative displacement, thus improving operational stability.

[0030] Example 2: This embodiment makes further structural optimizations based on Embodiment 1. Please refer to... Figures 1-3 Based on the above, refer to Figure 4 and Figure 5 .

[0031] In some embodiments, the gripper assembly 300 includes a gripper body 310 and a clamping block 320; the mounting end of the gripper body 310 is connected to the driving end of the gripper cylinder 200, and the clamping end of the gripper body 310 is connected to the clamping block 320. Under the driving action of the gripper cylinder 200, the gripper body 310 drives the clamping block 320 to clamp the rotor.

[0032] The clamping block 320 has a first contour groove 321 that is adapted to the clamping position on the rotor. By forming the first contour groove 321 on the clamping block 320, the clamping fit of the rotor can be improved, ensuring the stability of the rotor pumping and handling process.

[0033] As is known, during the process of transporting the compressor from the rotor cooling furnace to the main line, the rotor and the pump are connected together by a shaft. At this time, the rotor presents a cylindrical structure with a curved side. Therefore, in order to adapt to the curvature of the rotor side, in one example, the first contouring groove 321 is designed as an arc groove to achieve a complete fit with the side of the rotor.

[0034] The clamping block 320 is a silicone clamping block 320. Using silicone material avoids hard contact with the outer circumference of the rotor, preventing damage to the rotor surface and ensuring product quality. Furthermore, the silicone material facilitates processing, making it easier to form the first contour groove 321. Of course, the clamping block 320 can also be made of other elastic materials, as long as they provide a certain degree of elastic cushioning when clamping the rotor.

[0035] In some embodiments, the clamping block 320 has a second contoured groove 322 adapted to the clamping end of the gripper body 310; the clamping end of the gripper body 310 is embedded in the second contoured groove 322 and is locked to the clamping block 320 by screws to prevent positional movement between the clamping end of the gripper body 310 and the clamping block 320 during the clamping process, thereby ensuring the connection stability between the clamping end of the gripper body 310 and the clamping block 320.

[0036] For example, the clamping end of the gripper body 310 has a rectangular protrusion at the connection position with the clamping block 320. Correspondingly, a rectangular second contour groove 322 is formed on the clamping block 320, so that the clamping end of the gripper body 310 is embedded in the second contour groove 322. Then, the clamping end and the clamping block 320 are locked together by screws. In this way, the positional changes such as rotation between the clamping end and the clamping block 320 can be avoided.

[0037] In some embodiments, the number of gripper assemblies 300 is three, and the gripper cylinder 200 is a three-grip cylinder 200. The three-grip cylinder 200 drives the three gripper assemblies 300 to clamp the rotor, ensuring the clamping force on the rotor.

[0038] There are three clamping components 400, which are distributed at intervals along the circumferential direction to achieve a uniform clamping effect on the upper end face of the pump.

[0039] Specifically, each clamping component 400 is located in the middle of two adjacent gripper components 300. The clamping components 400 and gripper components 300 are staggered, which not only avoids mutual interference between them, but also ensures uniform force in different directions and improves handling stability.

[0040] It should be noted that in this embodiment, there is no specific limit to the number of gripper assembly 300 and clamping assembly 400. The number can be adjusted according to the actual operation requirements for handling the rotor pump.

[0041] Example 3: This embodiment further optimizes the structure based on embodiment 1. Please refer to section 1- Figure 3 Refer to the diagram. Figure 6 .

[0042] In some embodiments, the clamping assembly 400 includes a limiting rod 410, a spring 420, and a clamping shaft 430; the spring 420 is sleeved on the limiting rod 410, the upper end of the limiting rod 410 is connected to the second mounting plate 500, and the lower end of the limiting rod 410 is slidably connected to the clamping shaft 430; the two ends of the spring 420 abut against the upper ends of the second mounting plate 500 and the clamping shaft 430 respectively, and the spring 420 plays a buffering role, ensuring the clamping force of the clamping shaft 430 on the upper end face of the pump while avoiding damage caused by hard contact.

[0043] Specifically, under the action of external driving force, after the clamping shaft 430 descends to contact the upper end face of the pump, under the continued action of external driving force, the clamping shaft 430 will press against the upper end face of the pump. Correspondingly, a reverse force will be generated, causing the clamping shaft 430 to change position relative to the limit rod 410, that is, the clamping shaft 430 slides upward, which will squeeze the spring 420 to avoid damage to the pump due to excessive clamping force.

[0044] In some embodiments, the clamping shaft 430 has a first through hole 431 and a second through hole 432 connected in the axial direction. The diameter of the first through hole 431 is smaller than the diameter of the second through hole 432. The lower end of the limiting rod 410 passes through the first through hole 431, and the lower end of the limiting rod 410 is connected to a limiting piece 600. The diameter of the limiting piece 600 is larger than the diameter of the first through hole 431 and smaller than the diameter of the second through hole 432.

[0045] The first through hole 431 is located at the upper end of the second through hole 432, and both the first through hole 431 and the second through hole 432 are circular through holes. In one example, the lower end of the limiting rod 410 passes through the first through hole 431, and its lower end is connected to a limiting piece 600, which is located in the second through hole 432.

[0046] In practical applications, when the pressing shaft 430 presses the spring 420 upward, the pressing shaft 430 moves upward relative to the limiting rod 410. At this time, the lower end of the limiting rod 410 gradually enters the second through hole 432. That is, it is necessary to ensure that the pressing shaft 430 can move upward relative to the limiting rod 410. Under normal conditions, the pressing shaft 430 moves downward relative to the limiting rod 410 due to its own gravity and the elastic force of the spring 420. The pressing shaft 430 stops moving downward when the limiting piece 600 at the lower end of the limiting rod 410 is limited to the lower end of the first through hole 431. That is, the limiting piece 600 is used to limit the downward movement distance of the pressing shaft 430.

[0047] In this embodiment, the spring acts as a buffer, ensuring the clamping force of the clamping shaft on the upper surface of the pump while avoiding damage caused by hard contact.

[0048] The above description is merely an example and illustration of the structure of this invention, and while the description is specific and detailed, it should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these obvious substitutions all fall within the protection scope of this invention.
