Description

Technical Field

[0001] This utility model relates to the technical field of swashplate pump assembly equipment for high-pressure cleaners, and in particular to an integrated press-fit device for the water seal valve of a swashplate pump used in high-pressure cleaners. Background Technology

[0002] The swashplate pump is one of the core components of a high-pressure washer, and the assembly accuracy of its internal water seal and water valve directly affects the pump's sealing performance and operating efficiency. Currently, the assembly of the water seal and water valve in a swashplate pump is usually done in a step-by-step press-fit manner, first pressing the water seal and then pressing the water valve separately. This method is not only cumbersome and inefficient, but also makes it difficult to guarantee the relative positional accuracy between the water seal and the water valve, which can easily lead to leakage problems.

[0003] In addition, different models of swashplate pumps have different sizes and shapes of water seals and water valves. Existing press-fitting equipment can often only be adapted to specific models of products, which has poor adaptability and cannot meet diverse production needs.

[0004] To address this issue, we propose an integrated press-fit device for the water seal valve of a swashplate pump used in high-pressure cleaners. Utility Model Content

[0005] In order to overcome the problems existing in the prior art, this application provides an integrated press-fit device for the water seal valve of a swashplate pump for a high-pressure cleaner.

[0006] The integrated press-fitting device for the water seal valve of a swashplate pump used in a high-pressure washer, as provided in this application, adopts the following technical solution:

[0007] An integrated press-fit device for a water seal valve of a swashplate pump used in a high-pressure washer includes a workbench, a support platform fixed to the top surface of the workbench, a pump body placement seat lifted and installed directly above the support platform, a pump body positioning component on the top surface of the pump body placement seat, and several mounting ports penetrating the pump body placement seat inside the pump body positioning component; a water seal valve placement seat is provided on the top surface of the support platform corresponding to the pump body positioning component, wherein the water seal valve placement seat is integrally formed, and the top of the water seal valve placement seat has work positions for placing the water seal and the water valve respectively, and the seat penetrates the pump body mounting seat and corresponds to the pump head on the pump body placement seat.

[0008] By adopting the above technical solution, the swashplate pump body is first placed on the pump body positioning component on the top surface of the pump body mounting base. The positioning component precisely positions the pump body, aligning the mounting holes of the pump body with the mounting ports on the pump body mounting base. Next, the water seal and water valve are placed in their corresponding positions on the top of the water seal and water valve mounting base. Then, the pump body mounting base is driven to descend. At this time, the water seal and water valve are pressed into their corresponding positions on the pump body through the mounting ports on the pump body mounting base under downward pressure, completing the integrated press-fit of the water seal and water valve. Because the water seal and water valve mounting base is integrally formed and precisely corresponds to the pump body mounting base, the relative positional accuracy of the water seal and water valve can be guaranteed, improving the press-fit quality and production efficiency, while also adapting to the press-fit requirements of different models of swashplate pumps.

[0009] Preferably, the water seal valve placement seat has an upper limit seat and a lower limit seat on its top, wherein the upper limit seat is higher than the lower limit seat, the upper limit seat is located on the top of the water seal valve placement seat, and the lower limit seats are distributed in a ring on the water seal valve placement seat.

[0010] Preferably, the pump body mounting base is connected to the support platform via a lifting spring, and a guide rod passes through the center of the lifting spring. The top of the guide rod passes through the pump body mounting base and is limited by a limiting block.

[0011] Preferably, the limiting block is fitted onto the top of the guide rod, wherein the inner diameter of the limiting block is adapted to the guide rod, the outer diameter is smaller than the outer diameter of the pump body mounting seat, and the limiting block is fixedly connected by locking bolts.

[0012] Preferably, a limiting platform is also installed on the support platform, wherein the limiting platform does not contact the bottom surface of the pump body mounting base, and there is no less than one set of limiting platforms.

[0013] By adopting the above technical solution, the water seal is first placed on the upper limit seat at the top of the water seal valve placement seat, and the water valve is placed on the ring-shaped lower limit seat, achieving precise pre-positioning of both. Next, the pump head is placed on the pump body placement seat and positioned by the pump body positioning assembly. Then, the pump body placement seat descends along the guide rod under the driving force, the lifting spring is compressed, and the guide rod ensures stable descent. When the pump body placement seat descends to a certain position, it is restricted from further descent by the limit plate on the support platform, ensuring accurate pressing stroke. After pressing, the pump body placement seat returns to its original position under the elastic force of the lifting spring. If it is necessary to adjust the lifting range of the pump body placement seat, the locking bolts can be loosened, the limit block at the top of the guide rod can be moved to a suitable position, and then locked. The size design of the limit block avoids interference with other components.

[0014] Preferably, a support is vertically fixed to the top surface of the workbench, a lifting cylinder is fixed to the top surface of the support, a pressure plate is fixed to the bottom of the cylinder output end, and the pressure plate is located directly above the mounting plate.

[0015] Preferably, a start button is installed on the front of the workbench, and the start button includes two switches, one on the left and one on the right. Pressing the two switches simultaneously starts the lifting cylinder.

[0016] Preferably, a controller is provided on the front of the workbench, and the controller is connected to the lifting cylinder and the start button.

[0017] By adopting the above technical solution, the operating parameters of the lifting cylinder are first preset via the controller. When the device needs to be started, the operator must simultaneously press the two start buttons on the left and right sides of the worktable. The signal is transmitted to the lifting cylinder via the controller, causing the cylinder output end to extend, driving the pressure plate downwards to press the component located on the mounting plate directly below it. After pressing is completed, the controller controls the lifting cylinder output end to retract, and the pressure plate rises and resets, awaiting the next operation. This dual-switch synchronous start design effectively improves operational safety and avoids accidents caused by accidental activation.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This application enables one-time press-fitting of the water seal and water valve by means of an integrally molded water seal and water valve placement seat and pump body positioning assembly, which effectively simplifies the operation process, improves production efficiency, helps to ensure the relative positional accuracy between the water seal and water valve, thereby improving the sealing performance of the pump body and reducing the occurrence of leakage problems;

[0020] 2. The pump body placement seat in this application is installed by lifting springs and guide rods, which can adapt to pump bodies of different heights within a certain range, and the limiting block and limiting platform and other components can ensure the stability and accuracy of the pressing process;

[0021] 3. This application requires two switches to be pressed simultaneously to start the lifting cylinder via the start button on the front of the workbench, which increases the safety of operation. The controller can achieve precise control of the pressing process. The overall device can meet diverse production needs and has strong adaptability. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0026] This application discloses an integrated press-fit device for the water seal valve of a swashplate pump used in a high-pressure cleaner.

[0027] Reference Figure 1 and Figure 2 An integrated press-fit device for a water seal and water valve of a swashplate pump used in a high-pressure washer is disclosed. The device includes a workbench 1, a support platform 2 fixedly connected to the top surface of the workbench 1, a pump body placement seat 3 mounted flexibly above the support platform 2, a pump body positioning component 4 on the top surface of the pump body placement seat 3, and several mounting holes 41 penetrating the pump body placement seat 3 within the pump body positioning component 4. A water seal and water valve placement seat 5 is integrally formed on the top surface of the support platform 2, with positions on the top for placing the water seal and water valve respectively. The seat penetrates the pump body mounting seat and corresponds to the pump head on the pump body placement seat 3. First, the swashplate pump body is placed on the pump body positioning component 4 on the top surface of the pump body placement seat 3. The positioning component precisely positions the pump body, aligning the mounting holes of the pump body with the mounting holes 41 on the pump body placement seat 3. Then, the water seal and water valve are placed on their respective positions on the top of the water seal and water valve placement seat 5. Then, the pump body mounting base 3 is lowered. At this time, the water seal and water valve will be pressed into the corresponding positions of the pump body through the mounting port 41 on the pump body mounting base 3 under the downward pressure, completing the integrated press-fit of the water seal and water valve. Since the water seal and water valve mounting base 5 is integrally formed and precisely corresponds to the pump body mounting base 3, the relative positional accuracy of the water seal and water valve can be guaranteed, improving the press-fit quality and production efficiency, while also adapting to the press-fit requirements of different models of swashplate pumps.

[0028] Reference Figure 1 and Figure 2The water seal valve mounting base 5 has an upper limit seat 51 and a lower limit seat 52 on its top, with the upper limit seat 51 higher than the lower limit seat 52. The upper limit seat 51 is located on top of the water seal valve mounting base 5, and the lower limit seats 52 are distributed in a ring on the water seal valve mounting base 5. The pump body mounting base 3 is connected to the support platform 2 via a lifting spring 31, and a guide rod 32 passes through the center of the lifting spring 31. The top of the guide rod 32 passes through the pump body mounting base and is limited by a limiting block 33. The limiting block 33 is fitted onto the top of the guide rod 32, with its inner diameter matching that of the guide rod 32 and its outer diameter smaller than that of the pump body mounting base 3. The limiting block 33 is fixedly connected by a locking bolt 331. The support platform 2 is also equipped with a limiting platform 21, which does not contact the bottom surface of the pump body mounting base, and there is at least one such platform. First, place the water seal on the upper limit seat 51 at the top of the water seal valve placement seat 5, and place the water valve on the annularly distributed lower limit seat 52 to achieve precise pre-positioning of both. Next, place the pump head on the pump body placement seat 3, which is positioned by the pump body positioning assembly 4. Then, the pump body placement seat 3 descends along the guide rod 32 under the action of driving force, the lifting spring 31 is compressed, and the guide rod 32 ensures stability during the descent. When the pump body placement seat 3 descends to a certain position, it is restricted from further descent by the limit plate 21 on the support platform 2 to ensure accurate pressing stroke. After pressing is completed, the pump body placement seat 3 returns to its original position under the elastic force of the lifting spring 31. If it is necessary to adjust the lifting range of the pump body placement seat 3, the locking bolt 331 can be loosened, the limit block 33 at the top of the guide rod 32 can be moved to a suitable position and then locked. The size design of the limit block 33 can prevent it from interfering with other components.

[0029] Reference Figure 1 and Figure 2 A support bracket 11 is vertically fixed to the top surface of the workbench 1. A lifting cylinder 12 is fixed to the top surface of the support bracket, and a pressure plate 13 is fixed to the bottom end of the cylinder's output end. The pressure plate is located directly above the mounting plate. A start button 14 is installed on the front of the workbench 1, and the start button 14 includes two switches, left and right. Pressing the two switches simultaneously starts the lifting cylinder 12. A controller 15 is located on the front of the workbench 1, and the controller 15 is connected to the lifting cylinder 12 and the start button 14. The operating parameters of the lifting cylinder 12 are preset by the controller 15. When the device needs to be started, the operator must press the two start buttons 14 on the front of the workbench 1 simultaneously. The signal is transmitted to the lifting cylinder 12 through the controller 15, the cylinder output end extends, and the pressure plate moves downward to press the component located on the mounting plate directly below it. After pressing is completed, the controller 15 controls the output end of the lifting cylinder 12 to retract, and the pressure plate rises and resets, waiting for the next operation. This design of simultaneous start with two switches can effectively improve operational safety and avoid accidents caused by accidental touch.

[0030] Working process: First, place the swashplate pump body on the pump body positioning component 4 on the top surface of the pump body mounting base 3. The positioning component positions the pump body. Simultaneously, place the water seal and water valve on their respective positions on the top of the water seal and water valve mounting base 5, where they are fixed by the upper limit seat 51 and lower limit seat 52. Then, press the start button 14 on the front of the workbench 1 simultaneously with both hands. Upon receiving the signal, the controller 15 controls the lifting cylinder 12 to start, and the cylinder output drives the pressure plate to descend. The pressure plate presses down on the pump body mounting base 3, which moves downward along the guide rod 32 via the lifting spring 31 until the pump head on the pump body is aligned with the water seal and water valve mounting base 5. At this point, the water seal and water valve are aligned with their installation positions on the pump body. Next, the pressure plate continues to press down, simultaneously pressing the water seal and water valve into the corresponding installation port 41 on the pump body, completing the integrated press-fit. After the pressing is completed, the lifting cylinder 12 drives the pressure plate to rise, and the pump body placement seat 3 is reset under the action of the lifting spring 31. Finally, the swashplate pump body with the water seal valve pressed in can be removed.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
