Description

Technical Field

[0001] This utility model relates to a motor terminal rolling fixture, belonging to the field of tooling bending technology. Background Technology

[0002] A motor is a device that converts energy forms such as electrical, pneumatic, or hydraulic energy into mechanical energy. It is widely used in industrial manufacturing, transportation, and home appliances. Its main function is to drive the operation of mechanical equipment, generating rotational force through electromagnetic induction or pressure changes, thereby realizing the conversion and transfer of energy.

[0003] Motors typically require soldered terminal wires to their terminals for external power connection. However, some motor terminals cannot be directly soldered to secure external leads. This is because: firstly, motor terminals may experience additional mechanical stress during operation, leading to fatigue and breakage of the solder between the terminal and the wire; secondly, the solder may creep under the high temperature radiation generated by motor rotation, causing tiny gaps between the wire and the terminal, resulting in poor contact. Therefore, current non-soldering connection methods in the industry typically use terminal deformation to clamp the wire and form an effective electrical connection. This requires the terminal to form a channel through which the wire can pass, and this channel to clamp the wire under external force. Existing terminals are usually straight plates integrated with the motor cover. Therefore, a low-cost method to form this channel is manual bending, but manual bending is inefficient and produces inconsistent quality. There is an urgent need for a terminal rolling fixture to improve terminal bending efficiency. Utility Model Content

[0004] To address the shortcomings of the existing technology, the purpose of this utility model is to provide a motor terminal rolling fixture that improves terminal bending efficiency. The base has a positioning and mounting window that can accommodate the bottom of the motor cover, allowing the terminal at the top of the motor cover to protrude through the positioning and mounting window. A power component applies power to the bending component, causing it to fall along the support component towards the terminal until the U-shaped groove contacts the terminal. Initially, the terminal contacts the terminal via a chamfered inner edge of the U-shaped groove. Under continuous pressure, the terminal bends along the chamfered inner edge of the U-shaped groove to the chamfered inner edge of the other side of the U-shaped groove, continuing the bending process. This results in the terminal forming a channel through which a wire can pass. The operator can use tools to clamp the bent outer wall of the terminal, deforming it to engage with the wire, thus forming an effective electrical connection. This fixture can replace manual bending, improving work efficiency and ensuring consistent terminal bending quality.

[0038] Example

[0039] This embodiment aims to address the current industry-standard non-welded manual connection method used for motor terminal 101 connection, which requires the terminal 101 to form a channel 300 for the wire to pass through. However, existing terminal blocks 101 are typically straight plates integrated with the motor cover. Therefore, to form this channel 300, a low-cost method currently used is manual bending; however, manual bending is inefficient and results in inconsistent forming quality. Therefore, referring to… Figure 1-4 As shown, a motor terminal rolling fixture for improving the bending efficiency of terminal 101 is disclosed. The positioning and mounting window 11 of the base 1 can accommodate the bottom of the motor cover 100, so that the terminal 101 located at the top of the motor cover 100 is exposed through the positioning and mounting window 11. Power is applied to the bending member 2 through the power component, so that the bending member 2 can fall along the support member 3 towards the terminal 101 until the U-shaped groove 21 contacts the terminal 101. First, the inner side arc chamfer of the U-shaped groove 21 contacts the terminal 101. Under continuous pressure, the terminal 101 will bend along the inner side arc chamfer of the U-shaped groove 21 to the inner other side arc chamfer of the U-shaped groove 21 to continue bending, so that the terminal 101 bends to form a channel 300 through which the wire can pass. The operator can use a tool to clamp the outer wall of the bent terminal 101 to deform it and bite the wire to form an effective electrical connection. This fixture can replace manual bending, improve work efficiency and uniformly bend the terminal 101.

[0040] Reference Figure 1As shown, a motor terminal rolling fixture includes: a base 1, a bending member 2, a support member 3, and a power member. The top surface of the base 1 has a positioning mounting window 11 for placing a motor cover 100, allowing the terminals 101 on the motor cover 100 to protrude beyond the positioning mounting window 11. It should be noted that the positioning mounting window 11 is located in the middle of the top surface of the base 1, and its shape is adapted to the motor cover 100, allowing the motor cover 100 to be inserted into the positioning mounting window 11. For example, both the motor cover 100 and the base 1 are circular cylindrical components, and both are arranged in a circular shape. The bending member 2 is positioned directly above the positioning and mounting window 11. The bottom surface of the bending member 2 is provided with at least one U-shaped groove 21, which corresponds to the position of the terminal 101 on the motor cover 100. The inner chamfer of the at least one U-shaped groove 21 is rounded. For example, if there are two terminals 101 on the motor cover 100, distributed on both sides of the surface of the motor cover 100, then there are two corresponding U-shaped grooves 21. The terminal 101 may be inserted into the U-shaped groove 21 and first contact the inner side of the U-shaped groove 21 away from the center of the motor cover 100, so that both terminals 101 are bent towards the center of the motor cover 100. In this design, the support member 3 is slidably connected to the bending member 2, and the bending member 2 can move vertically along the support member 3. It should be noted that the support member 3 can be directly supported and fixed to the ground, and there will be no relative displacement between the support member 3 and the base 1 when the power member outputs power. In some embodiments, the support member 3 can also be a U-frame, with the U-shaped opening facing horizontally. The bending member 2 and the power member are arranged on the top inner side of the U-shape, and the base 1 is arranged on the bottom inner side of the U-shape. The power member is mounted on the support member 3, and its power output end is detachably connected to the bending member 2. The power output end of the power member can drive the bending member 2 to rise and fall along the support member 3, so that at least one U-shaped groove 21 can be inserted into one side of its interior until the bottom of at least one U-shaped groove 21 is bent and pushed out around the other side of its interior. The bending principle of the terminal 101 is achieved by guiding and pressing the terminal 101, which has metallic plasticity and deforms under force.

[0041] Reference Figure 1-4As shown, the positioning mounting window 11 is provided with a first positioning slot 12 adapted to the lug 102 of the motor cover 100. The first positioning slot 12 can engage with the lug 102 of the motor cover 100 so that the terminal 101 can be positioned directly below at least one U-shaped groove 21. In some embodiments, the opening of the first positioning slot 12 is V-shaped, and the first positioning slot 12 can limit the rotation of the motor cover 100 when accommodating the lug 102 of the motor cover 100. In some embodiments, the positioning mounting window 11 is provided with a second positioning slot 13, which is adapted to the pin 103 of the motor cover 100. When the positioning mounting window 11 is used to insert the motor cover 100, the pin 103 of the motor cover 100 is simultaneously inserted into the second positioning slot 13 to limit the rotation of the motor cover 100.

[0042] Reference Figure 1-4As shown, the motor terminal rolling fixture also includes a positioning component 5, which includes a turntable 51, a laser pointer 52 mounted on the bending member 2, and a limiting member 53. The top center of the turntable 51 is rotatably connected to the bottom of the base 1. The base 1 can rotate around the center of the positioning mounting window 11. The top of the turntable 51 is provided with a positioning scale 511, and one side of the base 1 is provided with an alignment scale that matches the positioning scale 511. When the positioning scale 511 is aligned with the alignment scale, the base 1 is aligned with the bending member 2, and the positioning and installation are completed. For example, the middle part of the turntable 51 is provided with a smooth concave part that matches the bottom of the base 1. The bottom of the turntable 51 can be inserted into the smooth concave part and rotate. To reduce the friction between the two, lubricating oil can be added to the smooth concave part, or a ball bearing can be used for indirect connection. In this configuration, the laser pointer 52's emitting end can illuminate the positioning scale 511; the limiting member 53 is movably connected to one side of the turntable 51, and one end of the limiting member 53 can abut against the base 1 under external force to limit the rotation of the base 1. For example, the limiting member 53 can be a screw, and one side of the turntable 51 is provided with a smooth, concave screw hole, with the screw and screw hole fitting together; the turntable 51 can rotate until the positioning scale 511 corresponds to the emitting end of the laser pointer 52, and the turntable 51 is locked by the limiting member 53. At this time, at least one U-shaped groove 21 corresponds to the position of the terminal 101. In some embodiments, the positioning assembly 5 further includes a rotating ring and a rocker arm disposed in the middle of the base 1. The rotating ring is evenly distributed with transmission teeth; for example, the transmission teeth are oriented vertically downwards. The rocking member is rotatably connected to the turntable 51. For example, a protrusion is provided on the top outer edge of the turntable 51, and the rocking member passes through the protrusion. The rocking member can rotate relative to the protrusion. The rocking member can be a horizontally arranged rod. One end of the rocking member is provided with a gear, the top of which meshes with the transmission teeth. The other end of the rocking member can rotate under the action of external force and drive the gear to rotate, thereby driving the base 1 to rotate relative to the turntable 51. The purpose is that when the entire fixture is installed on the workbench, the position of its base 1, specifically the position of the positioning mounting window 11, can be quickly aligned with the bending member 2.

[0043] Reference Figure 1-4 As shown, in some embodiments, the top of the bending member 2 is provided with a guide shaft 22, and the support member 3 is provided with a guide rail adapted to the guide shaft 22, so that the guide shaft 22 can slide along the guide rail; the end of the guide shaft 22 is provided with a shoulder, which can limit the guide shaft 22 from falling off the guide rail; the power member includes a hydraulic cylinder, which can drive the bending member 2 to move.

[0044] Reference Figure 1-4As shown, the motor terminal rounding fixture also includes at least one protective pin 6. The top of the base 1 is provided with a socket for inserting at least one protective pin 6, and the bottom of the bending member 2 is provided with a passage hole 14 that matches the protective pin 6. When the protective pin 6 is not aligned with the passage hole 14, the bending member 2 will first press against the protective pin 6 and will not be able to descend to the terminal 101 to perform the bending action.

[0045] Reference Figure 1-4 As shown, it also includes a connecting plate 7 that is detachably disposed at the bottom of the turntable 51. The connecting plate 7 is provided with at least one connecting hole, and the at least one connecting hole can be fixed to the worktable by a screw.
