Technical Field

[0001] The present application relates to the technical field of water valve assembly, and in particular to a water valve assembly device and an assembly process. Background Art

[0002] As an important component for controlling liquid flow in pipelines, water valves are becoming more and more popular in urban pipelines, household pipelines and industrial pipelines with the rapid development of cities and industries.

[0003] In the prior art, such as Figure 1 The structure of the water valve includes a valve body 1, a check valve plastic nut 11, a piston 12, a spring 13, and a check valve cover 14. A mounting hole 16 is opened on the valve body 1, and the check valve cover 14 is threadedly connected to the mounting hole 16 and is provided with a twisting portion 15 that is convenient for twisting with a tool. At the same time, the check valve plastic nut 11 and the check valve cover 14 are also provided with O-rings. During assembly, it is necessary to first sleeve and install the O-rings on the check valve plastic nut 11 and the check valve cover 14, and then install the check valve plastic nut 11, the piston 12, the spring 13, and the check valve cover 14 into the mounting hole 16 in sequence, and finally the check valve cover 14 is threadedly connected to the mounting hole 16.

[0004] During the assembly process of the water valve, whether the installation hole position and the subsequent parts installation position are aligned is an important factor affecting the assembly quality. Due to the precision of the injection molding production process, there will be deviations in the position of the installation holes on the produced valve body, and there will also be certain deviations when the staff clamps the valve body to the tooling, which will reduce the quality of the water valve after assembly. Summary of the invention

[0005] In order to improve the quality of water valves after assembly, the present application provides a water valve assembly device and an assembly process.

[0006] In the first aspect, the present application provides a water valve assembly device, which adopts the following technical solution:

[0007] A water valve assembly device comprises a body, a tool, an alignment mechanism and an assembly mechanism, wherein the assembly mechanism is used to assemble water valve parts, and the alignment mechanism comprises:

[0008] A movable seat is slidably arranged on the machine body, and the tooling is movably arranged on the movable seat in a horizontal plane and is used to clamp the valve body;

[0009] A moving assembly, arranged on the machine body and used for driving the moving seat to move;

[0010] The alignment piece is slidably arranged on the machine body in a direction close to or away from the mounting hole and is provided with a truncated cone-shaped alignment front surface that is convenient for extending into the mounting hole;

[0011] The positioning assembly is arranged on the movable seat and is used to position the tooling. After the alignment surface is abutted against the mounting hole and used to align the valve body, the positioning assembly positions the tooling. The movable assembly drives the movable seat and the valve body to move to the assembly mechanism for assembly and moves back to the original position after the assembly is completed.

[0012] By adopting the above technical solution, the valve body is installed on the tooling, and the positioning assembly is unlocked, so that the tooling is in an active state in the horizontal plane. The alignment piece is close to the mounting hole and extends into the mounting hole under the guidance of the alignment surface, so that the guide surface is pressed against the mounting hole to achieve alignment. During the alignment process, the valve body and the tooling are pushed to move in the horizontal plane. After the alignment is completed, the positioning assembly positions the tooling and the valve body, and the moving assembly is started to drive the moving seat and the tooling to move, so that the valve body is moved to the assembly mechanism, and the assembly mechanism sequentially installs multiple parts into the mounting hole.

[0013] The valve body is aligned through the cooperation of movable tooling and alignment parts, and finally the positioning assembly positions the tooling and the valve body so that the subsequently installed parts are aligned with the installation holes, thereby improving the quality of the water valve after assembly.

[0014] Optionally, the positioning component includes:

[0015] A plurality of balls are rotatably arranged on the upper surface of the movable seat and are used to support and position the lower surface of the tooling;

[0016] The pressing member is arranged on the movable seat and is pressed against the tooling for positioning or is moved away from the tooling for unlocking.

[0017] By adopting the above technical solution, the tooling moves on multiple ball bearings, so that the resistance is small when the alignment piece is inserted into the installation hole for alignment, thereby making the alignment more accurate; before alignment, the pressing piece is separated from the tooling to unlock the tooling, so that the tooling can move freely in the horizontal plane; after the alignment is completed, the pressing piece presses on the tooling for positioning, thereby improving the convenience of positioning the tooling, the structure is simple and stable, and the quality of the water valve after assembly is improved.

[0018] Optionally, the bottom of the tooling is detachably provided with a base that abuts against the positioning assembly through a connecting assembly, and a plurality of vertically downward guide rods are horizontally spaced apart on the base, and a plurality of guide holes are provided on the movable seat. The guide rods extend into the guide holes and have a diameter smaller than the diameter of the guide holes, and a limit plate is provided on the guide rod that protrudes outside the guide rod and is used to prevent the base from detaching from the movable seat.

[0019] By adopting the above technical scheme, different tooling can be replaced according to the size of the valve body to match it, thereby improving the adaptability of the assembly equipment; at the same time, multiple guide rods pass through multiple guide holes respectively, and the guide rods can slide on the guide holes. At the same time, the limit plate prevents the base from disengaging from the movable seat, thereby improving the stability of the pressing part when it is pressed on the base for positioning. At the same time, the guide rods cooperate with the guide rods and make the deviation between the mounting hole and the alignment part smaller when the tooling is installed on the base, thereby reducing the probability of the alignment front face being located outside the mounting hole during alignment, making it easier for the alignment front face to extend into the mounting hole, thereby improving the convenience and stability during alignment, and further improving the quality of the water valve after assembly.

[0020] Optionally, the connection component includes:

[0021] A plurality of connecting screws passing through the tooling and being threadedly connected to the base, wherein the connecting screws are provided with rotating columns for easy rotation;

[0022] A plurality of handles are provided on the tooling and are convenient for lifting and moving the tooling.

[0023] By adopting the above technical solution, the connecting screw is rotated by twisting the rotating column, thereby connecting or disconnecting with the base, and the handle is convenient for leveraging when moving the tooling, so that water valves of different sizes can be assembled, thereby improving the applicability of the structure.

[0024] Optionally, the assembly mechanism includes:

[0025] A lifting seat is vertically slidably arranged on the machine body and is used to clamp the plastic nut of the check valve and to install the plastic nut of the check valve into the installation hole;

[0026] A placing table, which is arranged on the machine body and is used to place the piston and the spring on the piston;

[0027] A clamping assembly is arranged on the machine body and passes through the spring to clamp the piston, and the clamping assembly is used to install the piston and the spring into the installation hole of the plastic nut of the check valve;

[0028] The rotating assembly is arranged on the machine body and clamps the check valve cover and is used to drive the check valve cover to rotate and then be threadedly connected to the mounting hole.

[0029] By adopting the above technical scheme, the plastic nut of the check valve is installed on the lifting seat, the piston is placed on the placement table, and then the spring is sleeved on the piston for positioning, the check valve cover is installed on the rotating assembly, and the moving assembly is started to drive the moving seat, the tooling and the valve body to move; the valve body is moved to the lifting seat, the lifting seat moves down to install the plastic nut of the check valve into the mounting hole, the lifting seat moves up, the valve body is moved to the clamping assembly, the clamping assembly clamps the piston through the spring, and then the clamping assembly installs the piston and the spring into the mounting hole, the clamping assembly moves up away from the valve body, the tooling continues to move to the rotating assembly, and the rotating assembly starts to thread the check valve cover to the mounting hole for positioning, thereby completing the assembly of the water valve.

[0030] The lifting seat, the placing table, the clamping assembly and the rotating assembly can be used to position multiple parts, and the structure is simple and compact, the operation is stable, and the quality of the water valve after assembly is improved. At the same time, the piston is clamped by the clamping assembly through the spring, thereby reducing the probability of the spring detaching from the piston, further improving the quality of the water valve after assembly.

[0031] Optionally, a sliding seat is provided on the upper edge of the machine body for sliding perpendicular to the sliding direction of the moving seat, a sliding plate is provided on the upper edge of the sliding seat for sliding parallel to the sliding direction of the moving seat, the rotating component is provided on the sliding seat and the clamping component is provided on the sliding plate, the clamping component is located on the side of the rotating component close to the placement table, and when the rotating component is aligned with the mounting hole, the placement table is located directly below the clamping component and on the outside of the valve body; when the moving seat drives the tooling to move, three workstations are formed at the alignment part, the lifting seat and the rotating component and movement between the three workstations is achieved.

[0032] By adopting the above technical solution, the moving assembly is started to drive the moving seat to move, so that the moving seat forms three workstations, which are respectively located at the alignment part, the lifting seat and the rotating assembly. The moving seat moves between the three workstations. When the moving seat moves to the second assembly position, the rotating assembly is aligned with the mounting hole, and the placement table is located directly below the clamping assembly and outside the valve body, so that it is convenient for the staff to place the piston and the spring on the placement table.

[0033] When the clamping assembly moves downward, the piston can be clamped through the spring. When the clamping assembly moves upward, the piston and the spring are moved upward. The sliding seat drives the clamping assembly close to the mounting hole and the rotating assembly is away from the mounting hole. Then the sliding plate drives the clamping assembly close to the mounting hole. The clamping assembly moves downward to place the piston and the spring into the mounting hole. After the clamping assembly moves upward, the sliding plate drives the clamping assembly away from the mounting hole, so that the clamping assembly and the rotating assembly are misaligned. Then the sliding seat drives the rotating assembly to move directly above the mounting hole, and the clamping assembly moves above the placement table, so that the placement table and the rotating assembly can be closer to the staff. At the same time, the placement table and the rotating assembly are misaligned with each other, so that there is no interference when placing parts on the placement table and the rotating assembly, and the distance moved during the assembly of the clamping assembly, the rotating assembly and the moving seat is shortened, thereby improving the quality and efficiency of the assembly.

[0034] Optionally, the clamping assembly comprises:

[0035] A clamping seat is vertically slidably arranged on a sliding plate;

[0036] A moving part, used for driving the clamping seat to move;

[0037] Two clamping sheets are slidably arranged on the clamping seat and pass through the spring and are used to clamp the piston;

[0038] The driving member is used to drive the two clamping pieces to approach each other to clamp the piston, or to drive the two clamping pieces to move away from each other to unlock the piston.

[0039] By adopting the above technical solution, the moving part drives the clamping seat and the two clamping plates to move downward, so that the two clamping plates pass through the spring and extend to the piston. The driving part drives the two clamping plates to approach each other to clamp the piston. The moving part starts to drive the clamping seat, the two clamping plates, the piston and the spring to move upward away from the placement table, and then the piston and the spring are installed in the mounting hole, thereby realizing the assembly of the piston and the spring.

[0040] At the same time, the two clamping pieces are in a state of being away from each other when passing through the spring, so the two clamping pieces can also limit the spring to a certain extent, making the spring position more correct, thereby improving the quality after assembly.

[0041] Optionally, the rotating assembly includes:

[0042] A rotating seat is vertically slidably arranged on the sliding seat;

[0043] A lifting member, used for driving the rotating seat to move;

[0044] A mounting seat, the mounting seat being arranged on the rotating seat;

[0045] A mounting ring, which is arranged on the mounting seat and is engaged with the check valve cover;

[0046] A rotating member, arranged on a rotating seat;

[0047] The rotating rod is arranged on the rotating member and passes through the mounting ring to be plugged into the screwing part to make the check valve cover and the rotating rod rotate simultaneously. The rotating member drives the rotating rod to rotate and move up and down at the same time and is used to thread the check valve cover to the mounting hole.

[0048] By adopting the above technical scheme, the check valve cover is snap-fitted and installed on the mounting ring, the screwing part is plug-fitted with the rotating rod, the lifting member drives the rotating seat, the mounting seat, the mounting ring, the rotating rod, the rotating member and the check valve cover to move downward at the same time, so that the check valve cover abuts against the mounting hole, the rotating member drives the rotating rod and the check valve cover to rotate and move downward at the same time, so that the check valve cover is threadedly connected to the mounting hole, the lifting member drives the rotating seat, the mounting seat, the rotating rod and the rotating member to move upward at the same time, so that the screwing part is disengaged from the rotating rod, and the rotating member drives the rotating rod to move upward and rotate, thereby improving the convenience of the assembly process and improving the assembly efficiency.

[0049] Optionally, the mounting seat abuts against the rotating seat and is fixed by two fixing components located on both sides of the mounting seat, and the fixing components include:

[0050] A fixed tube is arranged on the rotating seat, and an inclined guide surface is provided at one end of the fixed tube away from the mounting seat, and the distance from the top of the guide surface to the mounting seat is smaller than the distance from the bottom of the guide surface to the mounting seat;

[0051] A plug-in rod, which is slidably arranged and rotated on the fixed tube;

[0052] A paddle is arranged on one end of the plug-in rod away from the mounting seat. When the paddle rotates to contact with the top of the guide surface, the plug-in rod is plugged and installed on the mounting seat for positioning; when the paddle rotates to contact with the bottom of the guide surface, the guide surface pushes the paddle and the plug-in rod away from the mounting seat and causes the plug-in rod to disengage from the mounting seat.

[0053] By adopting the above technical solution, during installation, the mounting seat is pressed against the rotating seat, and the two paddles are rotated upward at the same time and the two connecting rods are pushed close to the mounting seat, so that the two fixing rods are plugged and installed on the opposite side walls of the mounting seat, and the paddles are in contact with the top of the guide surface. At this time, the inclined guide surface can position the paddles, and the paddles are pressed against the guide surface by gravity. The gravity between the connecting rods and the mounting seat will prevent the fixing plate from rotating, so that the fixing effect is better, thereby fixing the mounting seat.

[0054] If it needs to be removed, the two paddles rotate downward, and the two paddles act on the guide surface to drive the plug-in rod away from the mounting seat until the paddles rotate to contact the bottom of the guide surface, so that the plug-in rod is disengaged from the mounting seat, so that the mounting seat can be removed. Therefore, the assembly of check valve covers of different sizes can be realized, and the installation structure is simple and stable, which improves the applicability of the structure and the convenience of installation.

[0055] In the second aspect, the present application provides a water valve assembly device and assembly process, which adopts the following technical solutions:

[0056] A water valve assembly process comprises the following steps:

[0057] Install the O-ring: Install the O-ring onto the plastic nut and piston of the check valve, then apply lubricating oil;

[0058] Place accessories: Install the plastic nut of the check valve with the O-ring installed on the lifting seat, place the piston with the O-ring installed on the placement table, then put the spring sleeve on the piston for positioning, and install the check valve cover with the O-ring installed on the rotating assembly;

[0077] The present application is further described in detail below in conjunction with the accompanying drawings 2-10.

[0078] The embodiment of the present application discloses a water valve assembly device.

[0079] Reference Figure 2 and Figure 3 The water valve assembly equipment includes a body 2, a tooling 17, an alignment mechanism 3 and an assembly mechanism 5. The tooling 17 is arranged on the alignment mechanism 3. The tooling 17 is used to clamp and fix the valve body 1. The alignment mechanism 3 is used to align the mounting hole 16 on the water valve. Then the assembly mechanism 5 sequentially installs multiple parts into the mounting hole 16, so that the assembly mechanism 5 can align with the mounting hole 16 when assembling the parts, thereby improving the quality of the water valve after assembly.

[0080] The alignment mechanism 3 includes a moving seat 31, a moving assembly 32, an alignment piece 33, and a positioning assembly 34. The moving seat 31 is slidably installed on the upper surface of the body 2 along the length direction of the body 2; the moving assembly 32 is arranged on the body 2 and is used to drive the moving seat 31 to move. The moving assembly 32 adopts a motor nut screw structure. This structure is a prior art and will not be repeated here.

[0081] Reference Figure 3 and Figure 4The tooling 17 is designed according to the size and shape of the valve body 1. The tooling 17 is used to clamp the valve body 1 by using a screw and a clamping plate for positioning. The screw and clamping plate of different sizes of valve bodies 1 are different in size. At the same time, the mounting hole 16 is placed vertically upward when the valve body 1 is installed on the tooling 17. One or two valve bodies 1 can be clamped and installed on the tooling 17 at one time for assembly; the bottom of the tooling 17 is detachably mounted with a horizontal base 18 through a connecting component 4, and a horizontal mounting plate 171 is fixedly mounted on the bottom of the tooling 17. The mounting plate 171 and the base 18 are both rectangular and their length directions are parallel to the length direction of the body 2. A detector for detecting whether the valve body 1 on the tooling 17 is installed is fixedly mounted on the mounting frame 1 21.

[0082] The connecting assembly 4 includes a plurality of connecting screws 41 and a plurality of handles 42. There are four connecting screws 41 and they are located at the four corners of the mounting plate 171. The connecting screws 41 vertically pass through the mounting plate 171 and are threadedly connected to the base 18. A rotating column is coaxially fixedly installed on the top of the connecting screw 41. A protective plate 43 is sleeved on the connecting screw 41.

A mounting plate 1 23 and a mounting plate 24 are fixedly installed at intervals on the upper surface of the conveying seat 26 along the sliding direction of the moving seat 31. An electric push rod or a cylinder for driving the conveying seat 26 to move is fixedly installed on the mounting frame 1 21, thereby realizing the movement of the conveying seat 26, so that the conveying seat 26 is close to or away from the tooling 17.

[0084] The alignment piece 33 is vertically slidably mounted on the side wall of the mounting plate 1 23 near the tooling 17, and two alignment pieces 33 are arranged at intervals and are arranged one by one with the two valve bodies 1. The tooling 17 is movably arranged on the moving seat 31 in the horizontal plane, so that the tooling 17 can move in multiple directions in the horizontal plane; an electric push rod or a cylinder that simultaneously drives multiple alignment pieces 33 to move vertically is fixedly mounted on the mounting plate 1 23.

[0085] Reference Figure 3 , Figure 4 and Figure 5 The alignment part 33 is disc-shaped and has a truncated cone-shaped alignment surface 331 coaxially opened at the bottom. The bottom diameter of the alignment surface 331 is smaller than the top diameter. The bottom of the alignment surface 331 can extend into the mounting hole 16, and the alignment surface 331 is against the top of the mounting hole 16 for positioning, thereby realizing alignment of multiple valve bodies 1, so that the subsequent assembly mechanism 5 is aligned with the mounting hole 16 when assembling multiple parts.

[0086] Reference Figure 4 and Figure 6 The positioning assembly 34 is arranged on the moving seat 31 and is used to position the tooling 17. Before the tooling 17 needs to be aligned, the positioning assembly 34 is unlocked so that the tooling 17 can move freely in the horizontal plane; after the alignment is completed, the positioning assembly 34 positions the tooling 17. The positioning assembly 34 includes a plurality of balls 35 and a pressing member 36. A plurality of spherical seats are fixedly mounted on the upper surface of the moving seat 31, and a plurality of balls 35 are rotatably mounted on the upper surfaces of the plurality of spherical seats respectively; the base 18 is placed on the plurality of balls 35 for support, and a plurality of pressing members 36 are arranged at intervals, and the pressing members 36 are electric push rods or cylinders; the pressing member 36 is fixedly mounted on the lower surface of the moving seat 31 and the piston rod passes through the base 18 and extends to the top of the base 18, and the piston rod of the pressing member 36 presses on the lower surface of the base 18 for positioning, or the piston rod of the pressing member 36 is unlocked away from the tooling 17.

[0087] A plurality of guide holes 181 are provided on the base 18 at intervals and vertically penetrate the upper and lower surfaces of the base 18. A limiting hole 182 with a diameter larger than that of the guide hole 181 is coaxially provided at the bottom of the guide hole 181. A guide rod 183 is fixedly installed on the base 18 and located at the guide hole 181, and passes through the guide hole 181 vertically downward. A limiting disk 184 is coaxially provided at the bottom of the guide rod 183. The diameter of the limiting disk 184 is smaller than the diameter of the limiting hole 182 and larger than the diameter of the guide rod 183. The diameter of the guide rod 183 is smaller than the diameter of the guide hole 181.

[0088] Reference Figure 3 , Figure 4 and Figure 6 In the initial state, the axes of the multiple guide rods 183 and the multiple guide holes 181 coincide. The guide rods 183 and the limit plate 184 cooperate to position the base 18, the tooling 17 and the valve body 1, so that the error between the mounting hole 16 on the valve body 1 and the alignment piece 33 is within a certain range, reducing the probability that the alignment face 331 and the mounting hole 16 are too misaligned and cannot be inserted.

[0089] Reference Figure 3 , Figure 5The assembly mechanism 5 includes a lifting seat 51 and a placing platform 52. The lifting seats 51 are arranged on the mounting plate 24 at intervals along the sliding direction of the moving seat 31. Two lifting seats 51 are arranged at intervals and correspond to the two valve bodies 1 one by one. The lifting seat 51 includes a sliding portion 511 and a mounting portion 512.

A pushing member is fixedly installed on the side wall of the mounting plate 24 and on one side of each sliding portion 511. The pushing member can be an electric push rod or a cylinder, etc. The piston rod of the pushing member is connected to the sliding portion 511 and is used to drive the sliding portion 511 to move vertically.

[0090] The mounting portion 512 is detachably mounted on the bottom of the sliding portion 511 by means of screws, and the bottom of the mounting portion 512 extends to the bottom of the mounting plate 24. The mounting portion 512 is in the shape of a circular tube and is in a vertical state and has a certain elasticity. A plurality of avoidance holes 53 are spaced apart on the outer wall of the mounting portion 512. The avoidance holes 53 are connected to the bottom of the mounting portion 512 and to the inner and outer side walls of the mounting portion 512.
