Description

Technical Field

[0001] This utility model relates to a tooling for disassembling motor terminals, belonging to the technical field of compressor or motor tooling equipment. Background Technology

[0002] After installation, the compressor motor terminals may be damaged and need to be replaced. During terminal removal, other compressor components must be protected from damage. Therefore, current technology typically uses manual disassembly. However, the lack of suitable tools for manual disassembly leads to low efficiency. Furthermore, inexperienced operators can easily damage other components. Utility Model Content

[0003] The purpose of this utility model is to provide a tooling for disassembling motor terminals, which aims to reduce the impact damage to other compressor components during the disassembly process and improve disassembly efficiency.

[0004] The first technical solution of this utility model is: a motor terminal disassembly fixture, including a connector and a limiting member. The connector is located above the limiting member, and a vertically arranged collet is fixedly connected to the connector. The limiting member has a limiting hole for the collet to pass through. The upper end of the collet is fixedly connected to the connector, and the lower end of the collet is used to clamp the terminal. The lower end of the collet adopts a petal-shaped structure that gradually expands from top to bottom. When the connector is lifted upward, the collet moves upward, and the lower end of the collet is compressed by the limiting hole, thereby tightening the petal-shaped structure inward and clamping the terminal inside. A handle with an inverted U-shaped structure is provided above the connector. The two sides of the limiting member are respectively provided with upwardly extending connecting rods. The handle and the connector are both located between the two connecting rods. A guide seat is fixed inside each connecting rod. A guide hole is opened in the guide seat. The two vertical ends of the handle pass through the two guide holes and are fixedly connected to the two ends of the limiting member. Springs are respectively sleeved on the two vertical ends of the handle at the position between the guide seat and the connector.

[0005] A crossbar is connected between the upper ends of the two connecting rods, and there is a gap between the crossbar and the handle. The limiting member, the two connecting rods and the crossbar form a frame structure.

[0006] The limiting component, the two connecting rods, and the crossbar are integrated into a single structure.

[0007] After the handle drives the connector to fall, the connector and the limiting member fit together vertically.

[0008] The limiting member has at least two limiting holes, and the distance between adjacent limiting holes is equal to the distance between adjacent terminals.

[0009] The upper end of the collet has an internal threaded hole, and a tightening bolt is fixed inside the connector. The lower end of the tightening bolt is threaded into the internal threaded hole of the collet.

[0010] The second technical solution of this utility model is: a motor terminal disassembly fixture, including a connector and a limiting member. The connector is located above the limiting member, and a vertically arranged collet is fixedly connected to the connector. The limiting member has a limiting hole for the collet to pass through. The upper end of the collet is fixedly connected to the connector, and the lower end of the collet is used to clamp the terminal. The lower end of the collet adopts a petal-shaped structure that gradually expands from top to bottom. When the connector is lifted upward, the collet moves upward, and the lower end of the collet is compressed by the limiting hole, so that the petal-shaped structure tightens inward and clamps the terminal. A rear fixing plate is fixed behind the limiting member. The limiting member and the connector are both located in front of the rear fixing plate. A tensioning cylinder is provided in front of the rear fixing plate for driving the connector to move up and down, and a sliding cylinder is provided in rear of the rear fixing plate for driving the rear fixing plate to move up and down.

[0011] The cylinder body of the tensioning cylinder is located above the connecting piece, and the piston rod of the tensioning cylinder is set downward and fixedly connected to the connecting piece.

[0012] The slide cylinder includes a sliding seat, which is fixed to the back of the rear fixed plate. The sliding seat has a vertical groove that slides with the cylinder body of the slide cylinder. The piston rod of the slide cylinder is arranged downward and fixedly connected to the sliding seat.

[0013] The upper end of the collet has an internal threaded hole, and a tightening bolt is fixed inside the connector. The lower end of the tightening bolt is threaded into the internal threaded hole of the collet.

[0014] The beneficial effects of this utility model are as follows: This utility model is equipped with a collet. When in use, the collet is placed on the terminal to be removed, keeping the limiting member stationary. The connecting member is lifted upward to move the collet upward. The lower end of the collet is compressed by the limiting member, thereby contracting the inner hole of the collet to clamp the terminal. Then, an upward pulling force is applied to the limiting member as a whole to disassemble the terminal. The connecting member and the limiting member are reset, thereby resetting the collet and the terminal is released from the collet.

[0015] The first embodiment of this utility model is a manual tool. In use, the connecting piece is lifted by the handle, causing the collet to move upwards. The limiting piece is then manually moved upwards to disassemble the terminal. After releasing the handle, the connecting piece moves the collet downwards under the spring force, achieving a reset, and the terminal is removed from the collet. The second embodiment of this utility model uses a cylinder as the power mechanism. A tensioning cylinder lifts the connecting piece, causing the collet to move upwards. The lower end of the collet is compressed by the limiting piece, and the terminal is clamped inside the collet. Then, a sliding cylinder moves the rear fixing plate upwards, causing the limiting piece to move upwards and disassemble the terminal. The tensioning cylinder and the sliding cylinder then reset, thus resetting the collet.

[0016] This utility model is equipped with limiting components and connecting components, and uses collets to clamp the terminal block. During the disassembly process, the terminal block is subjected to uniform force, making disassembly convenient and stable. It is less likely to damage other parts of the compressor and improves disassembly efficiency.

[0017] In the preferred embodiment, the limiting member, two connecting rods, and crossbar form a frame structure, which facilitates gripping the limiting member and makes it easy to keep the limiting member stationary or to pull the limiting member upward.

[0018] In a preferred embodiment, multiple limiting holes are provided on the limiting member, allowing multiple collets to pass through simultaneously, thereby enabling the simultaneous disassembly of multiple terminals.

[0019] In the preferred embodiment, the collet is fixedly connected to the connector by tightening bolts. The overall structure is simple and the collet is easy to replace and disassemble. Attached Figure Description

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0030] Example 1: The structure of the motor terminal disassembly fixture in Example 1 of this utility model is as follows: Figures 1 to 3 As shown, the motor terminal disassembly fixture of this embodiment includes a connector 3 and a limiting member 2. The connector 3 is located above the limiting member 2. A vertically arranged collet 1 is fixedly connected to the connector 3. The limiting member 2 has a limiting hole for the collet 1 to pass through. The upper end of the collet 1 is fixedly connected to the connector 3. The lower end of the collet 1 is used to clamp the terminal. The lower end of the collet 1 adopts a petal-shaped structure that gradually expands from top to bottom. When the connector 3 is lifted upward, the collet 1 moves upward. The lower end of the collet 1 is compressed by the limiting hole, so that the petal-shaped structure tightens inward and clamps the terminal inside. The upper end of the collet 1 has an internal threaded hole. A tightening bolt 9 is fixed inside the connector 3. The lower end of the tightening bolt 9 is threadedly connected to the internal threaded hole of the collet 1.

[0031] The connector 3 is provided with an inverted U-shaped handle 4 above it. The limiting member 2 is provided with upwardly extending connecting rods 8 on both sides. The handle 4 and the connector 3 are both located between the two connecting rods 8. A guide seat 6 is fixed inside each connecting rod 8. A guide hole is opened in the guide seat 6. The two vertical ends of the handle 4 pass through the two guide holes and are then fixedly connected to the two ends of the limiting member 2. Springs 5 ​​are respectively sleeved on the two vertical ends of the handle 4 at the position between the guide seat 6 and the connector 3.

[0032] A crossbar 7 is connected between the upper ends of the two connecting rods 8. There is a gap between the crossbar 7 and the handle 4. The limiting member 2, the two connecting rods 8, and the crossbar 7 form a frame structure. The limiting member 2, the two connecting rods 8, and the crossbar 7 are integrally connected. After the handle 4 drives the connecting member 3 to fall, the connecting member 3 and the limiting member 2 fit together vertically.

[0033] The limiting member 2 has at least two limiting holes, and the distance between adjacent limiting holes is equal to the distance between adjacent terminals. The attached diagram only shows three limiting holes; the number of limiting holes can be flexibly set according to actual needs during actual use.

[0034] This embodiment is a manual disassembly tool. A handle 5 is installed on the connector. When in use, the collet is placed on the terminal to be removed. Hold the frame structure with one hand to keep the limiting member 2 stationary. Pull the handle 5 upward to lift the connector 3 upward, thereby moving the collet 1 upward. The limiting member 2 compresses the lower end of the collet 1, causing the inner hole of the collet 1 to contract and clamp the terminal. Then, apply an upward pulling force to the limiting member as a whole to disassemble the terminal. Release the handle, and under the elastic force of the spring 5, the connector 3 drives the collet 1 to reset, and the terminal is removed from the collet 1.

[0035] Example 2: The structure of the motor terminal disassembly fixture in Example 2 of this utility model is as follows: Figures 4 to 8As shown, the motor terminal disassembly fixture of this embodiment includes a connector 3 and a limiting member 2. The connector 3 is located above the limiting member 2. A vertically arranged collet 1 is fixedly connected to the connector 3. The limiting member 2 has a limiting hole for the collet 1 to pass through. The upper end of the collet 1 is fixedly connected to the connector 3. The lower end of the collet 1 is used to clamp the terminal. The lower end of the collet 1 adopts a petal-shaped structure that gradually expands from top to bottom. When the connector 3 is lifted upward, the collet 1 moves upward. The lower end of the collet 1 is compressed by the limiting hole, so that the petal-shaped structure tightens inward and clamps the terminal inside. The upper end of the collet 1 has an internal threaded hole. A tightening bolt is fixed inside the connector 3. The lower end of the tightening bolt is threaded into the internal threaded hole of the collet 1.

[0036] The limiting member 2 is fixed to the back of the rear fixing plate 10. The limiting member 2 and the connecting member 3 are both located on the front side of the rear fixing plate 10. The front side of the rear fixing plate 10 is provided with a tensioning cylinder 11 for driving the connecting member 3 to move up and down. The rear side of the rear fixing plate 10 is provided with a slide cylinder 12 for driving the rear fixing plate 10 to move up and down.

[0037] The cylinder body of the tensioning cylinder 11 is located above the connecting member 3, and the piston rod of the tensioning cylinder 11 is arranged downward and fixedly connected to the connecting member 2. The slide cylinder 12 includes a sliding seat 13, which is fixed to the back of the rear fixing plate 10. The sliding seat 13 is provided with a vertical groove that slides and engages with the cylinder body of the slide cylinder 12. The piston rod of the slide cylinder 12 is arranged downward and fixedly connected to the sliding seat 13.

[0038] Unlike Embodiment 1, this embodiment uses a cylinder as the power mechanism. The tensioning cylinder 11 pulls the connecting piece 3 upward, thereby driving the collet 1 upward. Under the action of the limiting piece 2, the space at the lower end of the collet 1 is compressed, causing the inner hole of the collet 1 shaft to shrink and clamp the terminal. The sliding table cylinder 16 drives the sliding seat upward, thereby moving the entire component on the rear fixing plate 10 upward. When the limiting piece 2 moves upward, the terminal is disassembled. The sliding table cylinder 16 resets, driving the sliding seat 13 to reset. The tensioning cylinder 11 resets, driving the connecting piece 3 to reset. The terminal falls out of the collet 1.

[0039] This utility model is equipped with limiting components and connecting components, and uses collets to clamp the terminal block. During the disassembly process, the terminal block is subjected to uniform force, making disassembly convenient and stable. It is less likely to damage other parts of the compressor and improves disassembly efficiency.

[0040] The embodiments and descriptions above are merely illustrative of the principles of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
