Description

Technical Field

[0001] The utility model relates to the technical field of graphite bases, in particular to a base connecting piece. Background Art

[0002] The graphite base is a material mixed with graphite material and binder. It has excellent thermal stability and electrical conductivity and is often used in various industrial fields. In order to ensure that the servo motor can drive the graphite base to rotate, a square connector is usually set between the servo motor and the graphite base.

[0003] However, the square structure of the existing connecting piece has certain defects: the connecting piece is easy to damage the graphite base during the clockwise or counterclockwise rotation or switching process, resulting in damage to the base or uneven force at the center of the base and cracking. It is necessary to improve the existing base connecting piece to reduce the damage to the base without affecting the function of driving the base to rotate; therefore, a base connecting piece is proposed to address the above problems. Utility Model Content

[0004] In order to make up for the shortcomings of the prior art, the square connector is prone to damage the graphite base during clockwise or counterclockwise rotation or switching, resulting in base damage or uneven force at the center of the base causing cracking. The utility model provides a base connector.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a base connector described in the utility model includes a base connector body; a pin is fixedly connected to the surface of the base connector body, a convex ring is fixedly connected to the surface of the base connector body, a mounting hole is opened in the convex ring, the mounting hole passes through the convex ring and the base connector body, a quick release mechanism is arranged in the pin, the base connector body is installed on the output shaft surface of the servo motor, and the base connector body is positioned by four pins on the surface of the base connector body to prevent slipping when the output shaft of the servo motor rotates, and at the same time, the existing base connector body is redesigned to change the base connector body from square to round to prevent damage to the graphite base caused by impact.

[0006] Preferably, the quick-release mechanism includes a through slot, which passes through the pin and the base connector body and connects them.

A pair of the squeeze blocks are symmetrically distributed about the central axis of the through slot, and a spring sheet is fixedly connected between the pair of squeeze blocks. After the base connector body is installed, the squeeze block in the pin will fit on the surface of the servo motor output shaft, and then the base is fit on the surface of the base connector body, and the base connector body is squeezed by the base, so that the two squeeze blocks rotate in a direction approaching each other and squeeze the spring sheet at the same time. After the base is separated from the base connector body, the spring sheet drives the squeeze block to reset, so that the base connector body is separated from the output shaft of the servo motor, and a gap appears to facilitate disassembly by the staff, so as to avoid the base connector body being too close to the output shaft of the servo motor after being squeezed.

[0007] Preferably, the spring sheet is of a "V" shape, and a bracket is fixedly connected in the through groove, and a sliding rod is slidably connected in the bracket, and a push plate is fixedly connected to one side of the sliding rod, and the side of the sliding rod away from the pushing plate is in contact with the spring sheet, and a spring is fixedly connected to one side of the pushing plate, and the other end of the spring is fixedly connected to the surface of the bracket.

[0009] Preferably, a slide groove is provided on the surface of the pin, and a protective cover is slidably connected to the slide groove through a spring. The surface of the pin, the side wall of the mounting hole and the surface of the base connector body are all chamfered. The chamfering can make it easier to install the base connector body. The protective cover can prevent impurities from entering the through groove and affecting the sliding effect of the slide rod when the base connector body is not in use.

[0010] Preferably, a groove is provided on the inner wall of the mounting hole, and the groove is an open spherical groove.

[0011] Preferably, the opening diameter of the groove is smaller than the diameter of the ball, and there are at least three balls, which are evenly distributed. The balls that are larger than the opening diameter of the groove can achieve the effect of embedding the balls into the groove to prevent them from falling off.

[0025] The quick-release mechanism includes a through slot 13, which passes through the pin 2 and the base connector body 1 and connects them.

[0026] The spring piece 11 is of a "V" shape, and a bracket 10 is fixedly connected in the through groove 13, and a sliding rod 9 is slidably connected in the bracket 10. A push plate 8 is fixedly connected to one side of the sliding rod 9, and the side of the sliding rod 9 away from the push plate 8 is in contact with the spring piece 11.

[0031] The opening diameter of the groove 15 is smaller than the diameter of the ball 16. At least three balls 16 are provided and are evenly distributed. When working, the ball 16 larger than the opening diameter of the groove 15 can achieve the effect of embedding the ball 16 into the groove 15 to avoid falling off. The design of more than three balls 16 can improve the stability of the base connector body 1 during installation and ensure centering.

[0032] Working principle: the base connector body 1 is installed on the output shaft surface of the servo motor, and the base connector body 1 is positioned by four pins 2 on the surface of the base connector body 1 to prevent slipping when the output shaft of the servo motor rotates. At the same time, the existing base connector body 1 is redesigned to change the base connector body 1 from a square to a round shape to prevent damage to the graphite base caused by impact. After the base connector body 1 is installed, the extrusion block 12 in the pin 2 will fit on the output shaft surface of the servo motor. Then, after the base is fitted on the surface of the base connector body 1, the base connector body 1 is squeezed by the base to make the two extrusion blocks 12 rotate in a direction close to each other, and at the same time, the spring sheet 11 is squeezed. After the base is separated from the base connector body 1, the spring sheet 11 drives the extrusion block 12 to reset, so that the base connector body 1 is separated from the output shaft of the servo motor, and a gap appears to facilitate disassembly by the staff, so as to avoid the base connector body 1 being too close to the output shaft of the servo motor after being squeezed.

[0033] When the extrusion block 12 rotates in the direction of approaching each other, the spring piece 11 will be squeezed to produce deformation, and the spring piece 11 will move in the direction close to the slide rod 9. The slide rod 9 is squeezed by the spring piece 11 to slide in the bracket 10, and at the same time, the push plate 8 is driven to move in the direction away from the through groove 13. Then, when the base is attached to the surface of the base connector body 1, the push plate 8 will be squeezed.

The chamfer 4 can make it easier to install the base connector body 1. The protective cover 3 can prevent impurities from entering the through groove 13 when the base connector body 1 is not in use, thereby affecting the sliding effect of the slide rod 9. The ball 16 can change the sliding friction into rolling friction, thereby reducing the friction between the mounting hole 5 and the motor output shaft, thereby reducing wear and improving the service life.
