[0020] like Figure 1 As shown, this utility model provides a high-voltage testing mechanism for a ring-shaped product 12, including: a base plate 1, a positive electrode wire 8, and a negative electrode wire 9; a support frame 2 is provided on the base plate 1; the support frame 2 is provided with: an inner support module 3 for supporting and fixing the inner side of the ring-shaped product 12, a first drive module 4 for driving the inner support module 3, an outer clamping module 5 for clamping and fixing the ring-shaped product 12 in cooperation with the inner support module 3, a support platform 6, a second drive module 7, and a control module (not shown in the figure); the control module (not shown in the figure) is electrically connected to the first drive module 4, the second drive module 7, the positive electrode wire 8, and the negative electrode wire 9 respectively; the positive electrode wire 8 is electrically connected to the support end of the inner support module 3; the negative electrode wire 9 is electrically connected to the clamping end of the outer clamping module 5.

[0021] In this embodiment, as Figure 1-3 As shown, the positive wire 8 and the negative wire are respectively connected to the positive and negative terminals of the external power supply. The external power supply is electrically connected to the control module (not shown in the attached figure), and the power supply is switched on and off through the control module (not shown in the attached figure). The control module (not shown in the attached figure) includes an electrical control cabinet and a controller, etc., wherein the controller can be a microcontroller, MCU, PLC, etc., which can control the orderly operation of various electrical components. In this embodiment, an MCU is selected. During operation, when the inner support module 3 and the external module clamp and fix the ring product 12, the control module (not shown in the attached figure) controls the external power supply to be turned on so that the ring product 12 in the clamped and fixed state can be subjected to high-voltage testing through the positive wire 8 and the negative wire 9. After the test is completed, the product is pushed out of the test position through the cooperation of the second drive module 7 and the support platform 6. The overall structure is stable and easy to install, which can realize the automated clamping and high-voltage testing of the ring product 12, effectively improving work efficiency and saving labor costs.

[0022] Further, the inner support module 3 includes: a first support arm 31, a second support arm 32, a first tension spring 33, a first inner support member 34, and a second inner support member 35 adapted to the first inner support member 34; a first slide rail 10 is provided on one side of the support frame 2; the first support arm 31 and the second support plate are respectively slidably mounted on both ends of the first slide rail 10; both ends of the first tension spring 33 are respectively fixedly connected to the first support arm 31 and the second support arm 32; the first inner support member 34 is fixedly connected to the first support arm 31; the second inner support member 35 is fixedly connected to the second support arm 32 and is arranged opposite to the first support member; the outer walls of the first inner support member 34 and the second inner support member 35 are both coated with conductive adhesive that can be electrically connected to the positive electrode wire 8; the output end of the first drive module 4 can be transmittedly connected to the first support arm 31 and the second support arm 32 respectively.

[0023] In this embodiment, the first inner support member 34 and the second inner support member 35 are semi-circular main structures, and are respectively installed at the top of the first support arm 31 and the second support arm 32 in a relative state. Under normal conditions, the first support arm 31 and the second support arm 32 are in a close-fitting state under the pull of the first pull rope spring. At this time, the first inner support member 34 and the second inner support member 35 are also in a close-fitting state to form a columnar structure so that the annular product 12 can be fitted onto the columnar structure. When the annular product 12 is fitted onto the first inner support member 34 and the second inner support member 35 and an inner support operation is required, the first drive module 4 works, and its output end pushes the first support arm 31 and the second support arm 32 to move in opposite directions on the first slide rail 10, thereby driving the first inner support member 34 and the second inner support member 35 to move in opposite directions to realize the support and fixation operation of the annular product 12. The overall structure is stable and easy to install.

[0024] Further, the first drive module 4 includes: a drive cylinder 41, a push arm 42, and a cam bearing 43; the drive cylinder 41 is installed on one side of the support frame 2, and its output end is fixedly connected to the push arm 42; the cam bearing 43 is installed on the push arm 42; the first support plate and the second support plate are provided with slots adapted to the cam bearing 43 on their sides that are close to each other; the cam bearing 43 can abut against the first support arm 31 and the second support arm 32 respectively; the drive cylinder 41 is electrically connected to the control module (not shown in the figure).

[0025] In this embodiment, the drive cylinder 41 is a mature technology product on the market and belongs to the prior art, so it will not be described in detail here. During assembly, the cam bearing 43 is installed in the lower middle part between the two support arms, and the slots on the two support arms cooperate to form a slot that matches the cam bearing 43. During operation, the drive cylinder 41 performs a pushing action, which in turn drives the cam bearing 43 to push upward through the push arm 42. During the upward pushing process, the cam bearing 43 abuts against the first support arm 31 and the second support arm 32 respectively, so as to drive the first support arm 31 and the second support arm 32 to move in opposite directions on the first slide rail 10 to realize its internal support operation.

[0026] Furthermore, the support platform 6 has a through hole; the first inner support member 34 and the second inner support member 35 pass through the through hole; the support platform 6 can be fitted with the first support arm 31 and the second support arm 32 respectively; the support platform 6 is coated with conductive adhesive that is electrically connected to the positive electrode wire 8.

[0027] In this embodiment, the support platform 6 has an L-shaped structure. The diameter of the through hole on the support platform 6 is larger than the inner diameter of the annular product 12 so that the product can be placed on the support platform. Then, the product is fixed by the cooperation of the first inner support member 34 and the second inner support member 35. After the product completes the high-pressure test, the second drive module 7 performs an ejection action, which in turn causes the support platform to perform an ejection action, so that it can lift the product.

[0028] Further, the second drive module 7 includes: a drive motor 71, a push rod 72, a push plate 73, and two pusher bearings 74; the push plate 73 is slidably mounted on the side of the support frame 2 away from the drive cylinder 41, and is fixedly connected to the lifting block 62; one end of the push rod 72 is fixedly connected to the push plate 73; the drive motor 71 is mounted on the bottom of the bottom, and its output end passes through the bottom plate 1 and is connected to the input end of the push rod 72; the two pusher bearings 74 are rotatably mounted on both sides of the top of the push plate 73, and can respectively abut against the input end of the outer clamping module 5; the drive motor 71 is electrically connected to the control module (not shown in the figure).

[0029] In this embodiment, the drive motor 71 is a stepper motor, which is a mature technology product on the market and will not be described in detail here. During operation, the drive motor 71 drives the push plate 73 to push out through the push rod 72. During the push-out process, the two pusher bearings 74 respectively abut against the outer clamping module 5 so as to drive the outer clamping module 5 to open up, so that the outer clamp can loosen the ring product 12 held by the outer clamp. At the same time, the push plate 73 drives the lifting block 62 and the support block 61 to push out, thereby pushing the loosened ring product 12 out of the test station.

[0030] Further, the outer clamping module 5 includes: a first clamping arm 51, a second clamping arm 52, a first clamping block 53, a second clamping block 54, and a second tension spring 55; a second slide rail 11 is provided on the side of the support frame 2 near the push block; the first clamping arm 51 and the second clamping arm 52 are slidably mounted on both ends of the second slide rail 11; the first clamping block 53 and the second clamping block 54 are respectively mounted on the first clamping arm 51 and the second clamping arm 52 in a relatively opposite manner; the first clamping block 53 and the second clamping block 54 are both coated with conductive adhesive; the two ends of the tension spring are respectively fixedly connected to the first clamping arm 51 and the second clamping arm 52; two curved arms 56 are respectively provided on the opposing surfaces of the first clamping arm 51 and the second clamping arm 52, which can respectively abut against the two pusher bearings 74 one-to-one.

[0031] In this embodiment, the surfaces of the first clamping block 53 and the second clamping block 54 facing each other are provided with openings that are adapted to the annular product 12, so as to clamp and fix the reversing product. When the outer clamping module 5 is in the clamping state, the first clamping arm 51 and the second clamping arm 52 move closer to each other under the tension of the second pull rope spring, thereby driving the first clamping block 53 and the second clamping block 54 to cooperate to realize the outer clamping operation of the annular product 12. When it is necessary to release the annular product 12, the drive motor 71 works, driving the push plate 73 and the two push bearings 74 on the push plate 73 to perform a lifting action. During the lifting process, the two push bearings 74 respectively abut against the first clamping arm 51 and the second clamping arm 52, thereby driving the first clamping arm 51 and the second clamping arm 52 to move in opposite directions, realizing the release operation of the annular product 12.

[0032] Further, the support frame 2 includes: a vertical plate 21, a V-shaped support seat 22, and a fixed seat 23; the fixed seat 23 is installed on the side of the vertical plate 21 near the push plate 73; the second slide rail 11 is installed on the fixed seat; the fixed seat 23 has a through groove for the push plate 73 and the push-pull bearing to pass through; the push plate 73 is slidably connected to the vertical plate 21; the V-shaped support seat 22 is installed on the side of the vertical plate 21 away from the push plate 73; the V-shaped support seat 22 is provided with a receiving groove for receiving the push arm 42 and the drive cylinder 41; the first clamping block 53 and the second clamping block 54 are provided with sliding grooves on their opposite sides; the top of both ends of the V-shaped support seat 22 is provided with guide bearings 24 corresponding to the sliding grooves; the guide bearings 24 are received in the sliding grooves.

[0033] In the specific implementation process, the positive wire 8 and the negative wire 9 are connected to the positive and negative terminals of the external power supply, respectively. A layer of conductive adhesive is wrapped around the two clamping blocks of the outer clamping module 5, the two inner support components of the inner support module 3, and the support block 61, covering the inner and outer rings of the annular product 12 and other contact parts. This conductive adhesive is conductive. When the outer clamping module 5, the inner support module 3, and the support block 61 cooperate to cover the entire product, the external power supply releases high voltage to test the product. If the insulation layer of the product is intact and the product is undamaged, the circuit is not conductive. The presence of defects in the product's appearance is determined by testing for open and open circuits. The control module (not shown in the attached diagram) synchronously controls the drive motor 71 to work in the forward direction (i.e., the drive motor 71 axially lifts upward) and the drive cylinder 41 to retract (the cylinder rod descends). At this time, the first support arm 31 and the second support arm 32 in the inner support module 3 are tensioned by the tension spring. In the state of the outer clamping module 5, the first clamping arm 51 and the second clamping arm 52 are pushed out by the bearing and slide in opposite directions. At the same time, the lifting block 62 and the support block 61 are lifted by the pushing action of the push plate 73. At this time, the mechanism is in the state of waiting to release material or the state of loosening material. When it is necessary to perform a high-pressure coating test on the product, the ring product 12 is placed on the support block 61 and the inner ring is fitted into the first inner support member 34 and the second inner support member 35. The drive cylinder 41 is started. The drive cylinder 41 drives the first support arm 31 and the second support plate seat to move in opposite directions on the first slide rail 10 through the push arm 42 to support the inner ring of the product. At the same time, the drive motor 71 works in the opposite direction (the drive motor 71 descends axially). The first clamping block 53 and the second clamping block 54 of the outer clamping module 5 move relative to each other under the action of the second pull rope spring to realize the outer clamping operation of the product. Then, the positive wire 8 and the negative guide are energized to perform a high-pressure coating test on the ring.

[0034] This utility model discloses a ring-shaped product high-pressure testing mechanism with a stable overall structure and convenient installation. It can realize the automated clamping and high-pressure testing of ring-shaped products, effectively improving work efficiency and saving labor costs.
