Description

Technical Field

[0001] This utility model relates to a pulling device, specifically a pulling device for a micro water pump umbrella-shaped seal. Background Technology

[0002] In the manufacturing process of miniature water pumps, the umbrella-shaped seal is a key component, and its installation quality plays a decisive role in the pump's sealing performance, waterproofing, and overall service life. Currently, traditional methods for installing umbrella-shaped seals in miniature water pumps mostly involve manual assembly or simple mechanical assistance. Manual assembly has many drawbacks. On the one hand, manual operation is inefficient and cannot meet the needs of large-scale production; on the other hand, the accuracy of manual operation is greatly affected by the operator's skill level and working condition, easily leading to problems such as seal installation position deviation and uneven pressure. This results in insecure seal installation, which in turn causes pump leakage, seal failure, and other malfunctions, increasing product defect rates and after-sales maintenance costs.

[0003] While some companies use simple mechanical installation equipment that improves installation efficiency to a certain extent, its inadequate structural design and lack of precise positioning and pressure control mechanisms make it difficult to guarantee the stability of the seal during its movement, especially during the clamping and pulling process. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a micro water pump umbrella-shaped seal pull-in device, which effectively solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model includes:

[0006] The machine casing has a worktable on it, and a turntable is installed on the worktable. The turntable is used to convey the umbrella-shaped seal of the water pump.

[0007] The mounting bracket is fixed to the worktable surface of the chassis;

[0008] The slide rail is vertically fixed to one side of the fixing frame;

[0009] The slider is slidably connected to the slide rail;

[0010] The first cylinder is installed at the bottom end of the fixed frame, and its piston rod is connected to the slider;

[0014] Multiple pneumatic clamps are mounted on the mounting bracket and are positioned corresponding to the water pump umbrella-shaped seal on the turntable;

[0015] The first cylinder drives the slider to rise and fall to move the pneumatic clamp to grip, pull in or release the seal, and the second cylinder drives the pressure block to apply pressure to the top of the seal.

[0016] Preferably, the turntable is a rotary conveyor disc with multiple circumferentially arranged stations for positioning the seals.

[0017] Preferably, the pneumatic clamps are circumferentially equidistantly distributed on the mounting frame, and the number is three.

[0018] Preferably, the slide rail is a linear guide rail, and the slider is a guide block that matches the linear guide rail.

[0031] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0032] Example 1, by Figure 1-4 This utility model provides a micro water pump umbrella-shaped seal pull-in device, comprising:

[0033] The chassis 1 has a worktable on it, and a turntable is installed on the worktable. The turntable is used to convey the umbrella-shaped seal of the water pump.

[0034] The mounting bracket 2 is fixed to the worktable surface of the chassis 1;

[0035] The slide rail 3 is vertically fixed to one side of the fixing frame 2;

[0036] Slider 4 is slidably connected to the slide rail 3;

[0037] The first cylinder 5 is installed at the bottom end of the fixed frame 2, and its piston rod is connected to the slider 4;

[0038] The second cylinder 6 is mounted on the top of the fixed frame 2;

[0039] The pressure block 7 is connected to the bottom end of the piston rod of the second cylinder 6;

[0040] Mounting bracket 8 is fixed to one side of the slider 4;

[0041] Multiple pneumatic clamps 9 are mounted on the mounting bracket 8 and are positioned corresponding to the water pump umbrella-shaped seal on the turntable;

[0042] The first cylinder 5 drives the slider 4 to rise and fall, thereby causing the pneumatic clamp 9 to clamp, pull in or release the seal, and the second cylinder 6 drives the pressure block 7 to apply pressure to the top of the seal.

[0043] The chassis 1 is the basic support structure of the entire device, and a worktable is provided on it. A rotary conveyor plate (turntable) is installed on the worktable. Multiple stations for positioning the seals are set around the turntable, which can realize the continuous and orderly conveying of the seals and provide a stable working platform for subsequent processing operations.

[0044] Fixed frame 2: It is firmly fixed on the worktable of the machine box 1 to support and fix important components such as slide rail 3, first cylinder 5, and second cylinder 6, to ensure the stability of the entire device structure and to ensure the accuracy and reliability of each component during operation.

[0045] Slide rail 3: A linear guide rail, vertically fixed to one side of the fixed frame 2. Slider 4 is a guide block that matches the linear guide rail, and the two form a sliding connection structure. The sliding of slider 4 on slide rail 3 provides guidance and support for the lifting and lowering movement of pneumatic clamp 9, ensuring that pneumatic clamp 9 is stable and accurate during the lifting and lowering process.

[0046] First cylinder 5: The first cylinder 5 is installed at the bottom of the fixed frame 2, and its piston rod is connected to the slider 4. As the power source for driving the slider 4 to rise and fall, the first cylinder 5 drives the slider 4 to move up and down along the slide rail 3 through telescopic movement, thereby controlling the pneumatic clamp 9 installed on one side of the slider 4 to perform clamping, pulling in or releasing operations on the seal.

[0047] Second cylinder 6: The second cylinder 6 is installed at the top of the fixed frame 2, and the bottom end of its piston rod is connected to the pressure block 7. The function of the second cylinder 6 is to drive the pressure block 7 to apply pressure to the top of the seal that has been pulled into place, so as to ensure that the seal is installed firmly and meets the specified installation standards.

[0048] Pressure block 7: The lower surface of pressure block 7 is provided with a groove that matches the shape of the top of the seal. This design can achieve a tight fit when pressure is applied to the top of the seal, ensuring uniform pressure and avoiding damage to the seal, while ensuring accurate installation of the seal.

[0049] Mounting bracket 8: Mounting bracket 8 is fixed to one side of slider 4, and three circumferentially equidistant pneumatic clamps 9 are mounted on it. The positions of the pneumatic clamps 9 correspond to the umbrella-shaped seal of the water pump on the turntable. The pneumatic clamps 9 are used to precisely clamp the seal on the turntable station and, driven by the first cylinder 5, complete the pulling action to accurately install the seal to the target position.

[0050] Both cylinder 5 and cylinder 6 are double-acting cylinders, controlled by an independent pneumatic control system. This system can precisely adjust parameters such as the cylinder's extension and retraction speed and pressure, achieving accurate control of the pneumatic clamp 9 and pressure block 7, meeting the needs of different working conditions.

[0051] Working principle: When this utility model is in use, the micro water pump umbrella-shaped seal pulling device operates by a turntable mounted on the workbench of the housing 1, which transports the water pump umbrella-shaped seal to the corresponding workstation (this is existing technology). Then, the first cylinder 5, mounted at the bottom of the fixed frame 2, drives the slider 4 to rise along the slide rail 3, causing the pneumatic clamp 9, mounted on the mounting bracket 8 on one side of the slider 4, to move upward and precisely clamp the seal. Next, the piston rod of the first cylinder 5 retracts, driving the slider 4 to move upward, and the pneumatic clamp 9 pulls the seal to the target position. Finally, the second cylinder 6, mounted at the top of the fixed frame 2, drives the pressure block 7 to apply pressure to the top of the seal, ensuring a secure installation. The specific process is as follows:

[0052] Seal clamping: The first cylinder 5 serves as the power source, with its piston rod extending to push the slider 4 upward along the slide rail 3, which is vertically fixed to one side of the mounting frame 2. Since the mounting frame 8 is fixed to one side of the slider 4, the pneumatic clamp 9 on the mounting frame 8 also rises accordingly. When the pneumatic clamp 9 rises to correspond to the position of the seal on the turntable station, the pneumatic clamp 9 is activated to precisely clamp the seal.

[0053] Seal Pull-in: After clamping is completed, the piston rod of the first cylinder 5 retracts, causing the slider 4 to slide downwards along the slide rail 3. At this time, the mounting bracket 8 and pneumatic clamp 9 connected to the slider 4 move down synchronously, and the pneumatic clamp 9 accurately pulls the clamped seal from the turntable station to the target installation position.

[0054] Sealing element pressure fixation: After the sealing element is pulled into place, the second cylinder 6 starts to work, its piston rod extends, driving the pressure block 7 connected to the bottom end to move downward. Because the lower surface of the pressure block 7 has a groove that matches the shape of the top of the sealing element, the pressure block 7 can fit tightly against the top of the sealing element, apply pressure evenly, and ensure that the sealing element is installed firmly, meeting the specified installation standards.

[0055] Beneficial effects: Dual-cylinder collaborative operation: The first cylinder 5 drives the slider 4 to rise and fall, which in turn drives the pneumatic clamp 9 to complete the action of "rising and clamping → falling and pulling", realizing the automated transfer of the seal from the turntable station to the target position.

[0056] The second cylinder 6 drives the pressure block 7 to apply pressure to the top of the pulled-in seal, ensuring a firm installation. The entire process requires no manual adjustment, shortening the processing cycle.

[0057] Pressure block and clamp matching design: The lower surface of pressure block 7 has a groove that matches the shape of the top of the seal. When pressure is applied, it can fit tightly against the seal, ensuring uniform pressure distribution, avoiding damage caused by excessive local force, and ensuring accurate installation position.

[0058] Multiple pneumatic clamps 9 on the mounting bracket 8 (such as 3 circumferentially equidistantly distributed clamps) correspond to the positions of the turntable station, enabling multi-point synchronous clamping of the seals and improving clamping stability and positional accuracy during the pulling process.

[0059] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
