Description

Technical Field

[0001] This utility model relates to the field of assembly equipment, and more specifically, to a double-joint ball valve assembly machine and assembly production line. Background Technology

[0002] Double-joint ball valves are a common type of valve used in piping systems. Their core feature is that both ends are designed with unions, which facilitates installation, disassembly, and maintenance. They are often used in household piping, HVAC systems, or industrial systems.

[0003] The assembly of existing double-joint ball valves is mostly done manually, requiring manual installation of the socket and nut onto the semi-finished workpiece. This method of operation is inefficient and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to overcome the problem of slow assembly efficiency of double-joint ball valves by manual assembly in the existing technology, and to provide a double-joint ball valve assembly machine that replaces the traditional manual assembly mode, which is more time-saving and labor-saving.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A double-joint ball valve assembly machine is provided, including a chassis and a frame disposed on the top of the chassis, a semi-finished product feeding device, a socket feeding device, a nut feeding device, and a workpiece displacement device respectively disposed on the frame. The top of the chassis is provided with a first station, a second station, and a third station. The semi-finished product feeding device is used to transfer semi-finished workpieces to the first station, the socket feeding device is used to transfer sockets to the second station, the nut feeding device is used to transfer nuts to the third station for installation, and the workpiece displacement device is used to transfer workpieces from the first station to the second station and from the second station to the third station.

[0007] In the assembly of a double-joint ball valve, a socket needs to be placed on the semi-finished workpiece before a nut is screwed in to complete the assembly. This invention provides a double-joint ball valve assembly machine. A semi-finished product feeding device picks up the semi-finished workpiece and transfers it to a first station. A workpiece displacement device transfers the semi-finished workpiece from the first station to a second station. A socket feeding device picks up the socket and transfers it to the second station, placing the socket on top of the semi-finished workpiece. Subsequently, the workpiece displacement device transfers the semi-finished workpiece and socket together from the second station to a third station. A nut feeding device transfers the nut to the third station and screws it in, fixing the semi-finished workpiece and socket, thus completing the assembly. This assembly machine design replaces the traditional manual assembly of double-joint ball valves, saving time and labor, reducing labor costs, and improving production efficiency.

[0008] Furthermore, the first, second, and third workstations are arranged sequentially along a first direction. The workpiece displacement device includes a translation mechanism connected to the frame, and a first and second driving mechanisms disposed at the output end of the translation mechanism and arranged along the first direction. The output end of the first driving mechanism is connected to the first clamping mechanism, and the output end of the second driving mechanism is connected to the second clamping mechanism. The first and second clamping mechanisms operate synchronously, allowing the workpiece at the first workstation to be transferred to the second workstation while simultaneously transferring the workpiece at the second workstation to the third workstation. This eliminates the need for multiple robotic arms, resulting in a simpler structure and eliminating the need for complex programs to ensure coordinated operation between the robotic arms, making operation more convenient.

[0009] Furthermore, the first driving mechanism includes a first driving member connected to the translation plate and a first driving plate connected to the output end of the first driving member, and the first clamping mechanism is connected to the first driving plate; the second driving mechanism includes a second driving member connected to the translation plate, a first lead screw connected to the output end of the second driving member, a connecting member threadedly connected to the first lead screw, and a second driving plate connected to the connecting member, and the second clamping mechanism is connected to the second driving plate. The second driving mechanism uses a lead screw, which is more stable than other driving members and can prevent the socket placed on the semi-finished part from falling off during transfer.

[0010] Furthermore, the first clamping mechanism includes a first clamping drive member fixed to the first drive plate and at least two first grippers connected to the output end of the first clamping drive member; the second clamping mechanism includes a second clamping drive member fixed to the second drive plate and at least two second grippers connected to the output end of the second clamping drive member; the translation mechanism includes a translation drive member fixed to the frame and a second lead screw installed at the output end of the translation drive member; the translation plate is provided with a lead screw seat; the second lead screw is threadedly connected to the lead screw seat; and the translation plate is slidably connected to the frame. The first clamping drive member and the second clamping drive member are respectively used to drive the first gripper and the second gripper to clamp the workpiece. The gripper generates a clamping force on the workpiece to grasp it. The translation drive member drives the lead screw to rotate, thereby driving the translation plate to move along the first direction, resulting in better stability of the lead screw transmission.

[0011] Furthermore, the semi-finished product feeding device includes a third driving member fixed to the frame, a fourth driving member connected to the output end of the third driving member, a third clamping driving member connected to the output end of the fourth driving member, and at least two third grippers disposed at the output end of the clamping driving member; the socket feeding device includes a fifth driving member fixed to the frame, a sixth driving member connected to the output end of the fifth driving member, a fourth clamping driving member connected to the output end of the sixth driving member, and at least two fourth grippers disposed at the output end of the fourth clamping driving member. Both the semi-finished product feeding device and the socket feeding device achieve movement of the clamping driving member in different directions through the mutual cooperation of the two driving members, and the clamping driving member can drive the grippers to clamp the workpiece.

[0012] Furthermore, the nut feeding device includes a seventh driving member fixed to the frame, an eighth driving member connected to the output end of the seventh driving member, a rotary driving member connected to the output end of the eighth driving member, a fifth clamping driving member connected to the output end of the rotary driving member, and at least two fifth grippers disposed at the output end of the fifth clamping driving member. The nut feeding device moves in two directions via the seventh and eighth driving members, causing the fifth clamping driving member to drive the fifth grippers to clamp the nut. When it moves to the third station, the rotary driving member is activated, screwing the nut into the semi-finished workpiece.

[0013] Furthermore, the device includes a feeding device for transferring the assembled double-joint ball valve to a feeding port located on the top of the machine housing. The feeding device includes a ninth drive member fixed to the frame, a tenth drive member connected to the output end of the ninth drive member, a sixth clamping drive member connected to the output end of the tenth drive member, and at least two sixth grippers located at the output end of the sixth clamping drive member. The feeding device, through the movement of the ninth and tenth drive members in two directions, causes the sixth clamping drive member to drive the sixth grippers to clamp the assembled double-joint ball valve and transfer it to the feeding port, thus inserting the double-joint ball valve into the feeding port.

[0014] An assembly line for a double-joint ball valve includes a double-joint ball valve assembly machine, a socket vibratory feeder device, a nut vibratory feeder device, a semi-finished product conveying device, a socket conveying device, and a nut conveying device. The inlet end of the socket conveying device is located at the outlet end of the socket vibratory feeder device, and the inlet end of the nut conveying device is located at the outlet end of the nut vibratory feeder device.

[0015] Furthermore, the semi-finished product conveying device includes a support fixed to the ground, a semi-finished product conveyor belt disposed on the support, and a semi-finished product driving component disposed on the support and used to drive the semi-finished product conveyor belt. A baffle plate is provided at the output end of the semi-finished product conveyor belt.

In addition, the above-mentioned driving components can also be electrically driven or hydraulically driven, etc.

[0037] The working principle of this embodiment is as follows:

[0038] In the assembly of a double-joint ball valve, a socket needs to be placed on the semi-finished workpiece before a nut is screwed in to complete the assembly. This invention provides a double-joint ball valve assembly machine. A semi-finished product feeding device 300 picks up the semi-finished workpiece and transfers it to the first station 110. A workpiece displacement device 600 transfers the semi-finished workpiece from the first station 110 to the second station 120. A socket feeding device 400 picks up the socket and transfers it to the second station 120, placing the socket on top of the semi-finished workpiece. Then, the workpiece displacement device 600 transfers the semi-finished workpiece and the socket together from the second station 120 to the third station 130. A nut feeding device 500 transfers the nut to the third station 130 and screws it in, fixing the semi-finished workpiece and the socket, thus completing the assembly of the semi-finished workpiece. This assembly machine design replaces the traditional manual assembly of double-joint ball valves, saving time and labor, reducing labor costs, and improving production efficiency.

[0039] The beneficial effects of this embodiment are as follows:

[0040] The first and second clamping mechanisms 660 operate synchronously, transferring workpieces from the first station 110 to the second station 120 while simultaneously transferring workpieces from the second station 120 to the third station 130. This eliminates the need for multiple robotic arms, simplifying the structure and eliminating the need for complex programming to ensure coordinated operation between robotic arms, making operation easier. The second drive mechanism 640 uses a lead screw, which is more stable than other drive components, preventing the sockets placed on the semi-finished parts from falling off during transfer. The first clamping drive 651 and the second clamping drive 661 drive the first and second grippers 652 to clamp the workpieces, respectively. The grippers exert clamping force on the workpieces to grasp them. The translation drive 611 drives the lead screw to rotate, thereby moving the translation plate 620 along the X-axis, resulting in better stability of the lead screw transmission. Both the semi-finished product loading device 300 and the socket loading device 400 utilize the cooperation of two drive components to enable the clamping drive to move in different directions, allowing the clamping drive to drive the grippers to clamp the workpieces.
