Description

Technical Field

[0001] This invention relates to the field of automated tooling technology, specifically to a tooling and method for installing a stop rod into a magnetic rotor during the installation process of an electronic expansion valve. Background Technology

[0002] The electronic expansion valve is a crucial component of an automotive air conditioning system. Referring to Chinese patent publication number CN211344062U (titled "Electronic Expansion Valve and its Stop Rod"), as per its patent appendix... Figure 1 The structure shown requires inserting the stop rod downwards to engage the magnetic rotor, in conjunction with its... Figure 2 , 3 As shown, the stop rod has two opposing arc-shaped arms and a central rod. During assembly, the central rod precisely inserts into the magnetic rotor in the vertical direction. Since the assembly operation of the stop rod and the magnetic rotor requires precision, it is necessary to design a fixture to install the stop rod into the magnetic rotor in order to ensure that the relative positions of the stop rod and the magnetic rotor are in the required state. Summary of the Invention

[0003] The purpose of this invention is to provide a tooling and method for installing a stop rod into a magnetic rotor, so as to automatically and accurately install the stop rod into the magnetic rotor.

[0004] The object of this invention is achieved as follows: a tooling for inserting a stop rod into a magnetic rotor, which automatically inserts the stop rod downward into the magnetic rotor, comprising:

[0005] A transverse main seat is horizontally slidably connected to a fixed frame. The transverse main seat is equipped with a transfer cylinder that drives it to move horizontally. The cylinder barrel of the transfer cylinder is fixedly connected to the fixed frame, and the piston rod of the transfer cylinder is connected to the transverse main seat.

[0006] The first lifting clamping mechanism and the second lifting clamping mechanism are installed side by side on one side of the transverse main seat. Both have clamping ends that automatically lift and hold the stop rod. In the initial state, the first lifting clamping mechanism and the second lifting clamping mechanism are located above the loading station and the stop rod positioning station, respectively. In the assembly state, the first lifting clamping mechanism and the second lifting clamping mechanism are located above the stop rod positioning station and the stop rod insertion station, respectively.

[0007] A stop rod positioning seat is fixedly installed at the stop rod positioning station for positioning the stop rod. The stop rod positioning seat has an upward-facing positioning groove for inserting and positioning the stop rod.

[0008] A magnetic rotor positioning seat that is fixedly installed at the stop rod insertion station for positioning the magnetic rotor.

[0009] The second lifting clamping mechanism is equipped with a stop rod positioning component for positioning the stop rod when clamping it.

[0010] As another aspect of this application, a method for inserting a stop bar into a magnetic rotor is proposed, comprising at least the following steps in sequence:

[0011] S1. Loading Step: In the initial state, the first lifting clamping mechanism and the second lifting clamping mechanism are located above the loading station and the stop rod positioning station, respectively. The stop rod is transported to the loading station and the first lifting clamping mechanism clamps the stop rod.

[0012] S2, Stop rod positioning step: Under the push of the transfer cylinder, the transverse main seat moves horizontally to the next station, so that the first lifting clamping mechanism and the second lifting clamping mechanism are respectively positioned above the stop rod positioning station and the stop rod insertion station. The first lifting clamping mechanism is directly facing the positioning groove of the stop rod positioning seat, and the stop rod is placed into the positioning groove of the stop rod positioning seat.

[0013] S3, Stop rod transfer step: When the second lifting clamping mechanism is aligned with the positioning groove of the stop rod positioning seat of the stop rod positioning station again, the second lifting clamping mechanism clamps the stop rod and pulls the stop rod out of the positioning groove of the stop rod positioning seat, and at the same time uses the stop rod positioning component to position the stop rod.

[0014] S4. Stop rod assembly steps: When the second lifting clamping mechanism is aligned with the magnetic rotor positioning seat of the stop rod insertion station again, the second lifting clamping mechanism drives the stop rod downward to insert the magnetic rotor.

[0015] The beneficial effects of this invention are as follows:

[0016] Driven by the transfer cylinder, the transverse main seat reciprocates horizontally, allowing the first lifting and clamping mechanism to switch back and forth between the loading station and the stop rod positioning station. Simultaneously, the second lifting and clamping mechanism can switch back and forth between the stop rod positioning station and the stop rod insertion station. The stop rod is transferred from the loading station to the stop rod positioning station for positioning, and then transferred from the stop rod positioning station to the stop rod insertion station. The magnetic rotor is positioned using the magnetic rotor positioning seat, allowing the stop rod to automatically insert into the magnetic rotor. The entire process can be automated, with high efficiency and guaranteed assembly accuracy. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-5 The present invention will be further illustrated by specific embodiments.

[0023] like Figure 1 , 2 As shown, a tooling for inserting a stop rod into a magnetic rotor, used to automatically insert the stop rod 24 downward into the magnetic rotor 25, includes:

[0024] The transverse main seat 7 is horizontally slidably connected to the fixed frame 8. The transverse main seat 7 is equipped with a transfer cylinder 6 that drives it to move horizontally. The cylinder barrel of the transfer cylinder 6 is fixedly connected to the fixed frame 8, and the piston rod of the transfer cylinder 6 is connected to the transverse main seat 7.

[0025] The first lifting clamping mechanism and the second lifting clamping mechanism are installed side by side on one side of the transverse main seat 7. Both have clamping ends that automatically lift and hold the stop rod 24. In the initial state, the first lifting clamping mechanism and the second lifting clamping mechanism are located above the loading station and the stop rod positioning station, respectively. In the assembly state, the first lifting clamping mechanism and the second lifting clamping mechanism are located above the stop rod positioning station and the stop rod insertion station, respectively.

[0026] A stop rod positioning seat 19 is fixedly installed at the stop rod positioning station for positioning the stop rod 24. The stop rod positioning seat 19 has an upward-facing positioning groove for inserting and positioning the stop rod 24. The stop rod positioning seat 19 is fixedly installed on the upper platform of the positioning bracket 21.

[0027] A magnetic rotor positioning seat 23 for positioning the magnetic rotor 25 is fixedly installed at the stop rod insertion station. The magnetic rotor positioning seat 23 is fixedly installed on the upper platform of the press-fitting station bracket 22. The magnetic rotor positioning seat 23 has an inner positioning groove, and the magnetic rotor 25 is inserted into the inner positioning groove of the magnetic rotor positioning seat 23.

[0028] The vibratory feeder 1 has a linear conveying track 2 that extends horizontally to the feeding station at its output end, so that several stop rods 24 are arranged in a horizontal straight line along the conveying track 2.

[0029] The second lifting clamping mechanism is equipped with a stop rod positioning component for positioning the stop rod 24 when clamping the stop rod 24.

[0030] like Figure 1, 4 As shown, the second lifting clamping mechanism includes a second lifting cylinder 12, a second lifting slide 13, and a second gripper cylinder 18 for clamping the stop rod 24. The second lifting slide 13 is slidably connected to the fixed frame 8. The stop rod positioning assembly is installed on the second lifting slide 13. The cylinder of the second lifting cylinder 12 is fixedly connected to the fixed frame 8. The piston rod of the second lifting cylinder 12 is connected to the second lifting slide 13. The second gripper cylinder 18 is installed on the lower side of the second lifting slide 13.

[0031] Combination Figure 2 , 3 As shown, the above-mentioned stop rod positioning assembly includes:

[0032] The cylinder of the stop rod positioning cylinder 14 is fixedly connected to the second lifting slide block 13.

[0033] A secondary lifting slide 15 is slidably connected to a second lifting slide 13.

[0034] A vertical lower extension column 16 is fixedly connected to the lower side of the auxiliary lifting slide 15, and the piston rod of the stop rod positioning cylinder 14 is connected downward to the auxiliary lifting slide 15.

[0035] A stop rod positioning sleeve 17 is detachably inserted into the lower extension post 16. The lower end of the stop rod positioning sleeve 17 protrudes from the lower end of the lower extension post 16, so that the stop rod 24 can be movably fitted with the stop rod positioning sleeve 17. Figure 3 As shown, the cross-sectional structure of the stop rod positioning sleeve shaft 17 is irregular, which matches the two arc-shaped arms of the stop rod 24, so that the two arc-shaped arms of the stop rod 24 can hold the stop rod positioning sleeve shaft 17 and slide along the axial length direction of the stop rod positioning sleeve shaft 17.

[0036] The clamping end of the second gripper cylinder 18 is close to the stop rod positioning sleeve shaft 17.

[0037] like Figure 3 As shown, the aforementioned stop rod positioning seat 19 is fixedly connected to a protruding shaft 20 on its upper side. When positioning the stop rod 24, the stop rod 24 is movably fitted with the protruding shaft 20 and inserted into the positioning groove of the stop rod positioning seat 19.

[0038] The automated tooling also includes:

[0039] The stop rod positioning seat 4 is located at the loading station. The stop rod positioning seat 4 is horizontally slidably set on the upper side of the positioning bracket 21. The stop rod positioning seat 4 is set side by side with the conveying track 2.

[0040] A side-pulling cylinder 3 is installed on the upper side of the positioning bracket 21 to drive the stop rod positioning seat 4 to slide horizontally.

[0041] Among them, such as Figure 1 , 5 As shown, the stop rod positioning seat 4 has a horizontal extension that is perpendicular to the conveying track 2 and faces the outlet of the conveying track 2. A positioning groove 4a with an opening facing the outlet of the conveying track 2 is provided on the horizontal extension to accommodate a stop rod 24 inserted horizontally. During the feeding stage, the stop rod positioning seat 4 is moved to the direct below the first lifting clamping mechanism by the side pull cylinder 3, so that the first lifting clamping mechanism faces the positioning groove 4a to clamp the stop rod 24.

[0042] The automated tooling also includes a material receiving sensor 5 installed on the horizontal extension of the stop rod positioning seat 4, which triggers a sensing signal when the stop rod 24 enters the positioning groove 4a.

[0043] The aforementioned first lifting and clamping mechanism includes:

[0044] The first lifting cylinder 9 has its cylinder barrel mounted on the fixed frame 8.

[0045] The first lifting slide 10 is slidably connected to the fixed frame 8, and the piston rod of the first lifting cylinder 9 faces downward and is connected to the upper side of the first lifting slide 10.

[0046] The first gripper cylinder 11 is used to hold the stop rod 24 and is connected to the first lifting slide 10.

[0047] Combination Figure 1-5 As shown in the figure, this embodiment proposes a method for installing a stop rod into a magnetic rotor using the above-mentioned automated tooling, which includes the following core steps in sequence.

[0048] S1. Loading Step: In the initial state, the first lifting clamping mechanism and the second lifting clamping mechanism are located above the loading station and the stop rod positioning station, respectively, and the stop rod 24 is transported to the loading station and the stop rod 24 is clamped by the first lifting clamping mechanism.

[0049] In step S1, the vibratory feeder 1 continuously outputs several stop rods 24 arranged in a straight line through the conveyor rail 2. The stop rods 24 are set upright, with their two arc-shaped arms on the upper side. The stop rod positioning seat 4 is close to the outlet of the conveyor rail 2, so that one stop rod 24 moves through the outlet of the conveyor rail 2 into the positioning groove 4a. The two arc-shaped arms of the stop rod 24 are above the positioning groove 4a so that it can be clamped. At the same time, the stop rod 24 triggers the incoming material sensor 5 to generate a sensing signal, giving the electronic control system a position feedback so as to proceed to the next step.

[0050] Then, the side-pulling cylinder 3 pushes the stop rod positioning seat 4 to the position directly below the first gripper cylinder 11 (loading station), and the first lifting cylinder 9 drives the first gripper cylinder 11 to move down, so that the first gripper cylinder 11 grips the stop rod 24.

[0051] S2. Stop Rod Positioning Step: Under the push of the transfer cylinder 6, the transverse main seat 7 moves horizontally to the next working position, so that the first lifting clamping mechanism and the second lifting clamping mechanism are respectively positioned above the stop rod positioning position and the stop rod insertion position. The first lifting clamping mechanism is directly aligned with the positioning groove of the stop rod positioning seat 19, and the stop rod 24 is placed into the positioning groove of the stop rod positioning seat 19. At the same time, as... Figure 3 As shown, the two arc-shaped arms of the stop rod 24 fit around the convex shaft 20 and are mounted on the upper side of the stop rod positioning seat 19, thereby adjusting the position of the stop rod 24 into place for subsequent assembly.

[0052] S3, Stop rod transfer step: When the second lifting clamping mechanism is aligned with the positioning groove of the stop rod positioning seat 19 of the stop rod positioning station again, the second lifting clamping mechanism clamps the stop rod 24 and pulls the stop rod 24 out of the positioning groove of the stop rod positioning seat 19, and at the same time uses the stop rod positioning assembly to position the stop rod 24.

[0053] In step S3, driven by the second lifting cylinder 12, the second gripper cylinder 18 moves downward so that its gripper can grasp the stop rod 24. Then, driven by the second lifting cylinder 12, it rises. The stop rod positioning cylinder 14 drives the extension column 16 and the stop rod positioning sleeve shaft 17 to move downward, so that the two arc-shaped arms of the stop rod 24 are movable and fit into the stop rod positioning sleeve shaft 17, thus completing the clamping and positioning operation of the stop rod 24 to prevent the stop rod 24 from shifting position when it is transferred to the assembly station.

[0054] S4. Stop rod assembly steps: When the second lifting clamping mechanism is aligned with the magnetic rotor positioning seat 23 of the stop rod insertion station again, the second lifting clamping mechanism drives the stop rod 24 downward to insert the magnetic rotor 25.

[0055] In step S4, combined Figure 1 As shown, the stop rod 24 is aligned downwards with the magnetic rotor 25. Driven by the second lifting cylinder 12, the second gripper cylinder 18 moves downwards to insert the stop rod 24 into the mounting hole of the magnetic rotor 25. Then, the second gripper cylinder 18 is released. Driven by the stop rod positioning cylinder 14, the lower extension column 16 presses the stop rod 24 into the mounting hole of the magnetic rotor 25, completing the assembly operation of the stop rod 24 and the magnetic rotor 25.

[0056] The above are preferred embodiments of the present invention. Those skilled in the art can make various modifications or improvements based on these embodiments. Without departing from the overall concept of the present invention, such modifications or improvements should fall within the scope of protection claimed by the present invention.
