Description

Technical Field

[0001] This utility model relates to the field of constant flow pump assembly technology, specifically to a constant flow pump positioning fixture. Background Technology

[0002] A constant flow pump is a type of pump that achieves a constant flow rate of liquid delivery by controlling the current or automatically adjusting the pump speed and changing the pump outlet valve. In the assembly process of a constant flow pump, positioning fixtures play a crucial role. Positioning fixtures can quickly and firmly clamp the constant flow pump housing. This function not only ensures the stability and accuracy of the pump housing during installation, but also greatly reduces the time required for installers to manually adjust the position of the pump housing, significantly improving assembly efficiency.

[0003] Currently, the positioning fixtures for constant flow pumps on the market have relatively simple functions, mainly focusing on fixing the pump housing. During the process of installing parts into the constant flow pump housing, installers usually need to continuously rotate the pump housing to make the installation position closer to their side, so as to facilitate smoother installation of parts. However, the existing positioning fixtures for constant flow pumps limit the flexibility and efficiency of assembly to a certain extent in this regard. Therefore, a new positioning fixture for constant flow pumps is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the existing constant flow pump positioning fixtures have relatively simple functions, which limit the flexibility and efficiency of assembly. This utility model provides a constant flow pump positioning fixture.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A constant flow pump positioning fixture includes four right-angled blocks arranged in a rectangle. The bottoms of every two adjacent right-angled blocks are fixedly connected by a U-shaped frame. A rotating plate is set in the middle of the four right-angled blocks. Each right-angled block has an arc-shaped groove on the side near the rotating plate. An arc-shaped rod is movably installed inside each arc-shaped groove. Each arc-shaped rod is fixedly connected to the rotating plate. The top of the rotating plate has four notches. An adjustable vertical plate is set inside each notch. A hydraulic rod is fixedly installed on the side wall of each vertical plate. A clamping plate is fixedly installed at the output end of each hydraulic rod. A drive assembly for rotating the rotating plate is set at the bottom of the rotating plate.

[0007] Furthermore, the drive assembly includes an arc-shaped rack, four arc-shaped racks arranged in a circle are fixedly installed at the bottom of the rotating plate, and two servo motors are fixedly installed at the top of the right-angle block on the right rear side. The output end of each servo motor is fixedly connected to a gear through the corresponding right-angle block, and each gear is meshed with the adjacent arc-shaped rack.

[0008] Furthermore, a rectangular block is fixedly installed at the top of the rotating plate corresponding to the edge of each notch, and a bolt is threaded onto each rectangular block. A threaded groove is opened on the side wall of each vertical plate, and the tail end of each bolt is threaded into the interior of the adjacent threaded groove. Several longitudinally equidistant limiting rods are fixedly installed on the side wall of each rectangular block.

[0009] Furthermore, the top of the rotating plate has a square opening, and the inner two side walls of the square opening have sliding grooves respectively. Several bearing rods are arranged inside the square opening, and sliders are fixedly installed at both ends of each bearing rod. Each slider is movably installed inside the adjacent sliding groove.

[0010] Furthermore, a C-shaped rod is provided on the rear side of the two right-angled blocks. The two right-angled blocks are movably installed inside the C-shaped rod. A T-shaped plate with an inverted T-shaped structure is fixedly installed at the bottom of the C-shaped rod. Support rods are provided on the opposite sides of the U-shaped frames on both sides. Circular holes are opened on the opposite sides of the U-shaped frames on both sides. A lead screw is movably installed inside each circular hole. Each lead screw is fixedly connected to the adjacent support rod. A nut is threaded onto each lead screw.

[0011] Furthermore, trapezoidal blocks are fixedly installed on the sides of the U-shaped frames that are far apart from each other, and limit blocks are fixedly installed on the sides of the U-shaped frames that are far apart from each other.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model first places the pump housing on top of the rotating plate, then activates each hydraulic rod to move the clamping plate closer to the pump housing to complete the clamping. Then, the parts are installed into the pump housing in sequence. When installing the parts, in order to ensure that the installation position is closer to the side, the installer can control the drive component to drive the rotating plate to rotate. When the rotating plate rotates to a suitable angle, it stops, so that the pump housing on the top of the rotating plate adjusts the angle synchronously, making it easier for the installer to install the parts more smoothly. When the four notches are aligned with the middle of the two adjacent right-angle blocks, the angle of the four vertical plates can also be adjusted to prevent the clamping plate from blocking the part to be operated.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] like Figures 1 to 5As shown, the device includes four right-angled blocks 1 arranged in a rectangle. The bottoms of every two adjacent right-angled blocks 1 are fixedly connected by a U-shaped frame 2. A rotating plate 3 is set in the middle of the four right-angled blocks 1. Each right-angled block 1 has an arc-shaped groove 4 on the side near the rotating plate 3. An arc-shaped rod 5 is movably installed inside each arc-shaped groove 4. Each arc-shaped rod 5 is fixedly connected to the rotating plate 3. The top of the rotating plate 3 has four notches 6. An adjustable vertical plate 7 is set inside each notch 6. A hydraulic rod 8 is fixedly installed on the side wall of each vertical plate 7. A clamping plate 9 is fixedly installed at the output end of each hydraulic rod 8. A drive assembly 10 for rotating the rotating plate 3 is set at the bottom of the rotating plate 3. It should be noted that, first, the pump housing is placed on top of the rotating plate 3, and then each hydraulic rod 8 is activated, causing each hydraulic rod 8 to drive the clamping plate 9 closer to the pump housing to complete the clamping. Then, the parts are installed into the pump housing in sequence. When installing the parts, in order to ensure that the installation position is closer to the side, the installer can control the drive assembly 10 to drive the rotating plate 3 to rotate. When the rotating plate 3 rotates to a suitable angle, it stops, so that the pump housing on top of the rotating plate 3 adjusts the angle synchronously, making it easier for the installer to install the parts more smoothly. When the four notches 6 are aligned with the middle of the two adjacent right-angle blocks 1, the angles of the four vertical plates 7 can also be adjusted to prevent the clamping plate 9 from blocking the part that needs to be operated.

[0025] like Figure 1 , Figure 2 As shown, the drive assembly 10 includes an arc-shaped rack 1001. Four arc-shaped racks 1001 arranged in a circle are fixedly installed at the bottom of the rotating plate 3. Two servo motors 1003 are fixedly installed at the top of the right-angle block 1 on the right rear side. The output end of each servo motor 1003 is fixedly connected to a gear 1002 through the corresponding right-angle block 1. Each gear 1002 is meshed with the adjacent arc-shaped rack 1001. It should be noted that when the two servo motors 1003 start together, they drive the corresponding gears 1002 to rotate. The two gears 1002 drive the four arc-shaped racks 1001 to rotate around the central axis in sequence, thereby causing the rotating plate 3 to rotate.

[0026] like Figures 1 to 3As shown, a rectangular block 11 is fixedly installed at the top of the rotating plate 3 corresponding to the edge of each notch 6. Each rectangular block 11 is threaded with a bolt 12. Each vertical plate 7 has a threaded groove 13 on its side wall. The tail end of each bolt 12 is threaded into the interior of the adjacent threaded groove 13. Several longitudinally equidistant limiting rods 14 are fixedly installed on the side wall of each rectangular block 11. It should be noted that when the four notches 6 are aligned with the middle of the two adjacent right-angle blocks 1, when the tail end of the bolt 12 is threaded into the interior of the adjacent threaded groove 13, the corresponding vertical plate 7 will be in a vertically upward state. When the tail end of the bolt 12 rotates out from the interior of the adjacent threaded groove 13, the vertical plate 7 can rotate to a vertically downward state. The vertical plate 7 will drive the hydraulic rod 8 and clamping plate 9 connected to it to rotate synchronously. The function of the limiting rod 14 is to facilitate positioning when the vertical plate 7 rotates back to the vertically upward state.

[0027] like Figure 5 As shown, the top of the rotating plate 3 has a square opening 21. The inner two side walls of the square opening 21 are respectively provided with sliding grooves 22. Several bearing rods 24 are arranged inside the square opening 21. Each bearing rod 24 has a slider 23 fixedly installed at both ends. Each slider 23 is movably installed inside the adjacent sliding groove 22. It should be noted that by moving the bearing rod 24 to the left or right, the bearing rod 24 will drive the corresponding two sliders 23 to slide inside the corresponding sliding groove 22. By changing the position of the bearing rod 24, the part of the pump housing that needs to be operated can be exposed, thereby facilitating operation.

[0028] like Figure 1 , Figure 4 As shown, C-shaped rods 15 are provided on the rear sides of the two right-angled blocks 1. The two right-angled blocks 1 are movably installed inside the C-shaped rods 15. A T-shaped plate 16 with an inverted T-shape structure is fixedly installed at the bottom of the C-shaped rods 15. Support rods 17 are provided on the opposite sides of the left and right U-shaped frames 2. Circular holes 18 are opened on the opposite sides of the left and right U-shaped frames 2. A screw rod 19 is movably installed inside each circular hole 18. Each screw rod 19 is fixedly connected to the adjacent support rod 17. A nut 20 is threaded onto each screw rod 19. It should be noted that when the two support rods 17 are rotated to a vertical position with respect to the ground, the two right-angled blocks 1 on the rear sides also rotate synchronously inside the C-shaped rods 15. After the angle of the support rods 17 is adjusted, the two nuts 20 are rotated to fix the current angle of the two support rods 17, so that the rotating plate 3 and the pump housing at the top of the rotating plate 3 are in an inclined state, which makes it easier to operate from the bottom of the pump housing.

[0029] like Figure 1 , Figure 4As shown, trapezoidal blocks 25 are fixedly installed on the side of the U-shaped frame 2 that is far apart from each other on both sides, and limit blocks 26 are fixedly installed on the side of the U-shaped frame 2 that is far apart from each other on both sides. It should be noted that both trapezoidal blocks 25 and limit blocks 26 play an auxiliary limiting role when the support rod 17 is rotated back to its original position.

[0030] In summary:

[0031] First, place the pump housing on top of the rotating plate 3. Then, activate each hydraulic rod 8 to move the clamping plate 9 closer to the pump housing for clamping. Next, install the components into the pump housing in sequence. To ensure the installation position is closer to the user, the installer can control the drive assembly 10 to rotate the rotating plate 3. Stop the rotating plate 3 when it rotates to the appropriate angle, so that the pump housing on top of the rotating plate 3 can be adjusted synchronously, making it easier for the installer to install the components. When the four notches 6 are aligned with the middle of the two adjacent right-angle blocks 1, the angles of the four vertical plates 7 can also be adjusted to prevent the clamping plate 9 from obstructing the part to be operated.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
