Description

Technical Field

[0001] The present invention relates to the technical field related to water meter assembly, and in particular to a water meter press-fitting device and method and a water meter assembly line. Background Art

[0002] During the assembly process of the water meter, the press-fitting of the ring cover and the meter body is an important step. Traditionally, this step is generally completed manually. The worker places the ring cover and the meter body in the tooling at a specific angle, and uses a press to press the products in the tooling to complete the assembly. This method is inefficient. The existing automated assembly equipment rarely involves positioning and adjustment of the meter body during the press-fitting process.

[0003] The accuracy of the position of the meter body is related to whether it can be correctly matched with the ring cover and pressed into place. The commonly used meter body positioning currently generally only adopts the clamping method. If there is a deviation in the initial placement of the meter body, the meter body will collide and scratch with the clamping claws or the surrounding support structure to a large extent, which may easily lead to scratches and other problems on the surface, which has a great impact on the assembly efficiency and quality of the product. In addition, if a clamping drive and other structures are set on each tooling, it will lead to increased equipment costs and increased control difficulty. In view of the above problems, this application is proposed. Summary of the invention

[0004] The purpose of the present invention is to provide a water meter press-fitting device and method and a water meter assembly line for realizing automated water meter press-fitting operations and achieving efficient and lossless meter body positioning effects so that the meter body can correctly cooperate with the ring cover.

[0005] The present invention is achieved through the following technical solutions.

[0006] A water meter press-fitting device of the present invention comprises a feeding module, a transfer module, a press-fitting module and a meter body positioning module, wherein the transfer module comprises a transfer body and a tool, wherein the tool comprises a meter body clamping body and a clamping drive, wherein at least two groups of the meter body clamping bodies are provided, respectively used to clamp two sides of the meter body, wherein the meter body positioning module comprises an initial positioning mechanism, wherein the initial positioning mechanism is used to initially return the meter body to a correct position so that the meter body approaches or reaches a correct position, thereby avoiding a large-scale scratching problem during a subsequent clamping process, wherein the initial positioning mechanism comprises a rotating body and an initial positioning clamping plate connected to the rotating body, wherein the rotating body is At least two groups are set, and two groups of corresponding initial positioning clamps are also set. The two groups of rotating bodies switch the separation and clamping states of the two groups of initial positioning clamps by rotating. The initial positioning clamps are not on the transfer route of the tooling when they are in the separation state, and do not affect the movement of the tooling. The loading module is used for loading parts and accessories. When positioning the parts, the parts are first clamped by the initial positioning clamps to make the initial adjustment of the position of the parts in the tooling, and then the parts are clamped by the surface body clamping body, and the parts and accessories are transferred to the press-fitting module by the transfer body, and the press-fitting module is used for press-fitting.

[0007] Furthermore, the initial positioning mechanism also includes a rack drive assembly and a rack, the rack drive assembly is used to drive the rack to move, and the rotating body is provided with a gear meshing with the rack, and the rotation of the rotating body is controlled by the action of the rack.

[0008] Furthermore, the clamping drive includes a driving rod, a sliding body, a base plate and a table body support plate, the sliding body is connected to the table body clamping body, the sliding body is installed on the base plate, the driving rod and the sliding body are transmitted to each other, and the spacing between the sliding bodies is adjusted by the action of the driving rod, and the table body support plate is arranged on the upper side of the sliding body to support the parts, and the table body positioning module also includes a clamping positioning driving mechanism, the clamping positioning driving mechanism is the power of the driving rod, and the clamping positioning driving mechanism is separately arranged from the driving rod. After the table body is clamped by the table body clamping body, the fixing effect of the table body is guaranteed during the subsequent transfer process. At the same time, since the clamping positioning driving mechanism and the tooling are separately arranged, there is no need to set a clamping drive on each tooling, which saves costs and reduces the control difficulty. When the subsequent pressing is completed and reaches the unloading station, a clamping positioning driving mechanism can also be arranged at the unloading station to control the release of the table body.

[0009] Furthermore, the press-fitting module comprises a press-fitting driving mechanism and a press-fitting body, and the surface contour of the press-fitting body matches the contour of the ring cover.

[0010] Furthermore, the transfer body is a turntable, and a plurality of toolings are evenly arranged on the turntable to achieve high-efficiency production.

[0011] Furthermore, the press-fitting module also includes a bottom support mechanism, which is arranged correspondingly to the press-fitting body and is respectively arranged on the upper and lower sides of the turntable. The bottom support mechanism is used to support the bottom of the turntable to avoid structural deformation caused by downward pressure.

[0012] Furthermore, the bottom support mechanism includes a support roller and a movable support assembly, the support roller is in rolling contact with the bottom of the turntable, and the movable support assembly uses a spring or a pneumatic cylinder to ensure that the support roller has a certain degree of floating distance.

[0013] Furthermore, the bottom plate is connected to the contact body, and the contact body is installed in a mounting hole on the turntable. During press-fitting, the bottom support mechanism directly supports the contact body of the tooling, thereby reducing the influence of pressure on the turntable.

[0014] A water meter press-fitting method, based on the water meter press-fitting device, comprises the following steps:

[0017] Press-fitting step: the loading module places the ring cover on the meter body, uses the transfer body to transfer the tooling to the press-fitting station, and uses the press-fitting module to perform press-fitting;

[0018] Unloading steps: Use the transfer body to transfer the tooling to the unloading station, and use the unloading module to grab the product to complete the unloading.

[0019] A water meter assembly line comprises the water meter pressing device mentioned above.

[0020] Beneficial effects of the present invention: This scheme realizes the automated assembly of water meters and improves efficiency. By setting an initial positioning mechanism, before the meter body is clamped and positioned, the initial positioning mechanism is used to initially return the meter body to its correct position or approach or reach the correct position. Then the meter body clamping body is used to clamp the meter body to avoid large scratches between the meter body and surrounding structures caused by direct clamping due to improper placement of the meter body. This ensures that the ring cover can cooperate with the meter body at the correct angle to ensure product quality. In addition, the initial positioning mechanism is not on the transfer route of the tooling when in a separated state and does not affect the movement of the tooling. In this scheme, since the clamping positioning drive mechanism and the tooling are separately arranged, there is no need to set a clamping drive on each tooling, which saves costs and reduces the difficulty of control.

DETAILED DESCRIPTION

[0029] Combine the following Figure 1-Figure 5 The present invention is described in detail.

[0030] Embodiment 1:

[0031] A water meter press-fitting device of the present invention, such as Figure 1 , including a loading module 4, a transfer module 6, a press-fitting module 8 and a meter body positioning module 9.

[0032] The loading module 4 generally adopts a robot arm to grab the ring cover 5 and the table body 10 for loading.

[0033] The transfer module 6 includes a transfer body and a tool 62, such as Figure 2 The transfer body is a circular turntable 61, which is connected to a transfer driving mechanism 64. A plurality of tooling 62 are evenly arranged on the turntable 61. In this embodiment, five groups of tooling 62 are provided to realize multi-station synchronous operation and achieve high-efficiency production effects.

[0034] like Figure 4 , Figure 5 The tooling 62 includes a watch body clamping body 621 and a clamping drive. The watch body clamping body 621 is provided with at least two groups, which are respectively used to clamp the two sides of the watch body 10. The clamping drive includes a driving rod 622, a sliding body 623, a bottom plate 624 and a watch body support plate 625. The bottom plate 624 is connected to the turntable 61. The sliding bodies 623 and the watch body clamping bodies 621 are provided with the same number and are connected to each other. The sliding bodies 623 are slidably installed on the bottom plate 624. The driving rod 622 and the sliding bodies 623 are connected by transmission. The distance between the sliding bodies 623 is adjusted by the action of the driving rod 622.

[0035] Optionally, a transmission structure such as a crank rocker structure, an inclined plane transmission mechanism, etc. can be used between the driving rod 622 and the sliding body 623 to control the movement of the sliding body 623 through the left and right movement of the driving rod 622 .

[0036] In this embodiment, Figure 5 The sliding body 623 is provided with an inclined hole structure, and the driving rod 622 is provided with a transmission pin. When the driving rod 622 moves, the transmission pin transmits the inclined hole structure to make the sliding bodies 623 approach or move away from each other.

[0037] The watch body support plate 625 is disposed on the upper side of the sliding body 623 for supporting components. The contour of the watch body clamping body 621 preferably matches the contour of the watch body 10 to achieve a better clamping effect.

[0038] like Figure 4 The watch body positioning module 9 includes a clamping positioning drive mechanism 92, which is the power of the driving rod 622. The clamping positioning drive mechanism 92 is separately arranged from the driving rod 622. After the watch body 10 is clamped by the watch body clamping body 621, the fixing effect of the watch body 10 is guaranteed in the subsequent transfer process. At the same time, since the clamping positioning drive mechanism 92 and the tooling 62 are separately arranged, there is no need to set a clamping drive on each tooling 62, which saves costs and reduces the control difficulty. When the subsequent press-fitting is completed and reaches the unloading station, a clamping positioning drive mechanism 92 can also be set at the unloading station to control the release of the watch body 10.

[0039] The clamping and positioning drive mechanism 92 can adopt a cylinder, and the piston rod of the cylinder completes the clamping action by pushing or pulling the drive rod 622. When pulling is used to achieve clamping, an electromagnet or a suction cup needs to be set at the end of the piston rod to achieve connection with the drive rod 622.

[0040] The watch body positioning module 9 includes an initial positioning mechanism 91, which is used to initially return the watch body 10 to a correct position or to make it approach or reach a correct position, thereby avoiding a large scratch problem during the subsequent clamping process.

[0041] like Figure 4 The initial positioning mechanism 91 includes a rotating body 914 and an initial positioning clamping plate 915 connected to the rotating body 914. At least two groups of rotating bodies 914 are arranged and installed on a rotating base. Two groups of corresponding initial positioning clamping plates 915 are also arranged. The two groups of rotating bodies 914 adjust the separation and clamping state switching of the two groups of initial positioning clamping plates 915 by rotation. When the initial positioning clamping plates 915 are in the separated state, they are not on the transfer route of the tooling 62 and do not affect the movement of the tooling 62.

[0042] Specifically, the initial positioning mechanism 91 also includes a rack drive assembly 912 and a rack 913. The rack drive assembly 912 can use a cylinder. The rack drive assembly 912 is used to drive the rack 913 to move up and down. A gear 916 meshing with the rack 913 is provided on the rotating body 914. The rotation of the rotating body 914 is controlled by the action of the rack 913. When not clamped, the rotating body 914 is in an unfolded state, and the tooling 62 can be transferred to this workstation.

[0043] The initial positioning mechanism 91 further includes a supporting connecting body 911 , which is connected to the mounting support 81 , and a rack driving assembly 912 and a rotating base in the initial positioning mechanism 91 are mounted on the supporting connecting body 911 .

[0044] When positioning the parts, the parts are first clamped by the initial positioning clamp 915 to make the initial adjustment of the position of the parts in the tooling 62, and then the parts are clamped by the watch body clamping body 621. The parts and accessories are transferred to the press-fitting module 8 by the transfer body and press-fitted by the press-fitting module 8.

[0045] like Figure 2 The press-fitting module 8 includes a press-fitting driving mechanism 82 and a press-fitting body 83 , both of which are mounted on the mounting support portion 81 . The press-fitting driving mechanism 82 can be a cylinder or a hydraulic cylinder, and the surface contour of the press-fitting body 83 matches the contour of the ring cover 5 .

[0046] The press-fitting module 8 also includes a bottom support mechanism 84 , which is correspondingly arranged to the press-fitting body 83 and respectively arranged on the upper and lower sides of the turntable 61 . The bottom support mechanism 84 is used to support the bottom of the turntable 61 to prevent structural deformation caused by downward pressure.

[0047] Embodiment 2:

[0048] On the basis of Example 1, the bottom support mechanism 84 includes a support roller 841 and a movable support assembly 842. The movable support assembly 842 uses a spring or a pneumatic cylinder to ensure that the support roller 841 has a certain degree of floating distance.

[0049] The bottom plate 624 is connected to the contact body 63, and the contact body 63 is installed in the installation hole on the turntable 61. The bottom of the contact body 63 protrudes from the bottom surface of the turntable 61, and the support roller 841 rolls in contact with the bottom of the turntable 61. When in contact with the bottom surface of the contact body 63, the support roller 841 drops to a certain height, and the dropped height is slightly less than the height of the bottom of the contact body 63 protruding from the bottom surface of the turntable 61, so that the bottom support mechanism 84 can withstand most of the downward pressure and reduce the force on the turntable 61. In order to ensure that the tooling 62 can remain stable when the bottom support mechanism 84 supports the contact body 63, a floating support or an elastic support can be provided on the upper end surface of the turntable 61.

[0050] A water meter press-fitting method, based on the water meter press-fitting device in any of the above embodiments, comprises the following steps:

[0051] Loading step: using the loading module 4 to place the meter body 10 between the meter body clamping bodies 621 of the tooling 62, and using the transfer body to transfer the tooling 62 to the meter body positioning station;

[0052] The step of positioning the watch body: driving the rotating body 914 to rotate, so that the initial positioning clamping plate 915 clamps the end position of the watch body 10, so that the watch body 10 is as close to the correct position as possible in the tooling 62, and the watch body clamping body 621 is used to clamp the watch body 10 to complete the positioning of the watch body 10, and ensure that the position of the watch body 10 in the tooling 62 is fixed during the subsequent transfer process;

[0053] Press-fitting step: the loading module 4 places the ring cover 5 on the meter body 10, uses the transfer body to transfer the tool 62 to the press-fitting station, and uses the press-fitting module 8 to perform press-fitting;

[0054] Unloading step: Use the transfer body to transfer the tooling 62 to the unloading station, and use the unloading module 7 to grab the product to complete the unloading.
