Description

Technical Field

[0001] This utility model relates to the field of three-dimensional flow impeller technology, specifically a clamping auxiliary structure for installing a cast high-speed three-dimensional flow impeller. Background Technology

[0002] The three-dimensional flow impeller is a relatively advanced type of impeller. Its advanced nature stems from its energy-saving and consumption-reducing working principle. The impeller is the heart of a water pump, and its design directly determines the pump's head, flow rate, and efficiency, making the three-dimensional flow impeller popular in the market. The three-dimensional flow theory of jet wakes involves continuously and infinitely dividing the three-dimensional space within the impeller to establish a complete dynamic model. This model is more efficient, reducing energy loss during flow and making the pump more efficient.

[0003] CN222608810U discloses a fixture for machining a cast high-speed three-dimensional impeller. The fixture has a worktable fixedly connected to the upper surface of a base plate, and a fixing device fixedly connected to the upper surface of the worktable. The fixing device includes a chuck, a slide movably connected to the side surface of the chuck, and jaws fixedly connected to the upper surface of the slide. First, the clamping size of the jaws is adjusted according to the impeller's model and size. The motor is started, driving a lead screw to rotate, which in turn rotates a movable block, causing the jaws on the upper surface of the slide to slide in a groove. Next, the sliding arm on the lower surface of the slide extends and retracts via a telescopic rod, thereby adjusting the clamping size of the jaws to hold the impeller to be machined.

[0004] The existing fixture for machining a high-speed three-dimensional impeller with integral casting has the following disadvantages: the device cannot clamp according to the shape of the three-dimensional impeller, and if the jaws are forcibly pressed against the surface of the three-dimensional impeller, it is easy to damage the surface of the three-dimensional impeller.

[0005] Therefore, a clamping auxiliary structure for installing a cast high-speed three-dimensional flow impeller is proposed to solve the problems mentioned above. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a clamping auxiliary structure for installing a cast high-speed three-dimensional flow impeller, which can solve the problem that forcibly pressing the claws against the surface of the three-dimensional flow impeller can easily damage the surface of the three-dimensional flow impeller.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a clamping auxiliary structure for installing a cast high-speed three-dimensional impeller, comprising a support frame, two support plates fixedly connected to the inner wall of the support frame, a worktable fixedly connected to one side of the two support plates, through holes on both sides of the worktable, a rotating rod rotatably sleeved inside the worktable, a sleeve rotatably sleeved on the surface of the rotating rod, a first movable plate fixedly connected to the surface of the sleeve, a first rotating shaft fixedly connected to one side of the first movable plate, a second movable plate rotatably sleeved on the surface of the first rotating shaft, a second rotating shaft fixedly installed on the surface of the second movable plate, a fixing block rotatably sleeved on the surface of the second rotating shaft, an expansion ball fixedly installed on the inner wall of the worktable, an air pipe fixedly connected to the lower end of the expansion ball, an air cylinder fixedly installed at the bottom end of the air pipe, a piston slidably sleeved on the inner wall of the air cylinder, and a pressure plate fixedly installed on the surface of the rotating rod.

[0009] Preferably, a first telescopic cylinder is fixedly installed inside the support frame, and the telescopic end of the first telescopic cylinder is fixedly installed on the lower end face of the fixed block.

[0013] Preferably, a second protective pad is fixedly installed on the upper surface of the workbench, and the expansion ball is fixedly installed at the center of the upper surface of the workbench.

[0014] Compared with the prior art, this utility model provides a clamping auxiliary structure for mounting a cast high-speed three-dimensional flow impeller, which has the following advantages:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1 - Figure 4This embodiment of a clamping auxiliary structure for installing a cast high-speed three-dimensional flow impeller includes a support frame 1. Two support plates 2 are fixedly connected to the inner wall of the support frame 1. A workbench 3 is fixedly connected to the opposite side of the two support plates 2. Through holes 5 are opened on both the left and right sides of the workbench 3. A rotating rod 6 is rotatably sleeved inside the workbench 3. A sleeve 9 is rotatably sleeved on the surface of the rotating rod 6. A first movable plate 10 is fixedly connected to the surface of the sleeve 9. A first rotating shaft 12 is fixedly connected to one side of the first movable plate 10. A second movable plate 11 is rotatably sleeved on the surface of the first rotating shaft 12. A second rotating shaft 13 is fixedly installed on the surface of the second movable plate 11. A fixing block 14 is rotatably sleeved on the surface of the second rotating shaft 13. An expansion ball 22 is fixedly installed on the inner wall of the workbench 3. An air pipe 21 is fixedly connected to the lower end face of the expansion ball 22. An air cylinder 16 is fixedly installed at the bottom end of the air pipe 21. A piston 17 is slidably sleeved on the inner wall of the air cylinder 16. A pressure plate 7 is fixedly installed on the surface of the rotating rod 6.

[0026] The workbench 3 is fixedly installed by the support plate 2, so that the workbench 3 can be stably fitted into the support frame 1. The workbench 3 is used to place and hold the three-dimensional impeller and to press against the clamping structure. In order to improve the stability of the three-dimensional impeller above the workbench 3, the purpose can be achieved by internal and external clamping.

[0027] Among them, the pressure plate 7 is set as two pieces, and the first protective pad 8 is fixedly installed on the opposite side of the two pressure plates 7;

[0028] By setting the first protective pad 8, when the first protective pad 8 abuts against the surface of the three-dimensional impeller, the friction between it and the three-dimensional impeller can be increased, thereby improving protection and stability.

[0029] The first telescopic cylinder 15 is fixedly installed inside the support frame 1, and the telescopic end of the first telescopic cylinder 15 is fixedly installed on the lower end face of the fixed block 14.

[0030] The first telescopic cylinder 15 can control the fixed block 14 to move downward, and the fixed block 14 drives the second movable plate 11 and the first movable plate 10 to move. The model of the first telescopic cylinder 15 is set as MXQ.

[0031] The top end of the air pipe 21 penetrates the inner wall of the workbench 3 and is connected to the inside of the expansion ball 22, while the bottom end of the air pipe 21 is connected to the air cylinder 16.

[0032] By setting up the air pipe 21, the gas in the air cylinder 16 is transported into the expansion ball 22, causing it to inflate.

[0033] Among them, a fixing rod 18 is fixedly connected to one side of the piston 17, and one end of the fixing rod 18 is fixedly connected to the center of one side of the piston 17.

[0034] By setting a fixed rod 18, when the fixed rod 18 is driven, the piston 17 can be controlled to slide in the air cylinder 16, pushing the gas in the air cylinder 16 into the air pipe 21.

[0035] Among them, a second telescopic cylinder 19 is fixedly installed inside the support frame 1, and the telescopic end of the second telescopic cylinder 19 is fixedly installed at one end of the fixed rod 18.

[0036] By setting a second telescopic cylinder 19, the movement direction of the fixed rod 18 and the piston 17 can be controlled, and the model is set as FNQ;

[0037] The upper surface of the workbench 3 is fixedly equipped with a second protective pad 4, and the expansion ball 22 is fixedly installed at the center of the upper surface of the workbench 3.

[0038] The working principle of the above embodiments is as follows:

[0039] In use, firstly, the operator places the three-dimensional impeller to be clamped downwards onto the workbench 3, and then fits the inside of the three-dimensional impeller onto the surface of the expansion ball 22. At this time, the second telescopic cylinder 19 is driven to control the fixed rod 18 to move towards the air cylinder 16, and controls the piston 17 to slide along the inner wall of the air cylinder 16, pushing the gas in the air cylinder 16 into the air pipe 21. Then, the air pipe 21 delivers the gas to the inner wall of the expansion ball 22, causing it to expand and increase its volume. Through the expansion of the expansion ball 22, its surface can abut against the inner wall of the three-dimensional impeller, completing the internal clamping. Then, the first telescopic cylinder is driven to control the fixed block 14 to move downwards, causing the fixed block 14 to drive the second rotating shaft 13 to rotate. Simultaneously, the second movable plate 11 is pulled downwards, and the second movable plate 11 pulls the first movable plate 10, causing the first movable plate 10 to use the sleeve 9 to control the rotating rod 6 to drive the pressure plate 7 to flip towards the three-dimensional impeller, and control the first protective pad 8 to press against the surface of the three-dimensional impeller, thereby achieving external clamping of the three-dimensional impeller. This device improves the stability of the three-dimensional impeller on the worktable 3 by clamping the three-dimensional impeller from both inside and outside. Through the flat setting of the pressure plate 7 and the first protective pad 8, one side of the first protective pad 8 can be stably pressed against the flat surface of the three-dimensional impeller, preventing damage caused by contact with the protruding part of the three-dimensional impeller, while also ensuring the stability of the pressure on the three-dimensional impeller.

[0040] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
