Description

Technical Field

[0001] The utility model relates to the technical field of reduction motors, in particular to a reduction motor component. Background Art

[0002] A reduction motor is an integration of a reducer and a motor. This integration is also commonly called a gear motor or gear motor. It is usually assembled by a professional reducer manufacturer and supplied as a complete set with a motor. The reduction motor is widely used in the steel industry, machinery industry, etc. The advantages of using a reduction motor are simplified design and space saving. The characteristics of the reduction motor are high efficiency and reliability, long service life, easy maintenance, and wide application. Its stages can be divided into single-stage, two-stage and three-stage gear reduction motors, and the main installation arrangements are expansion, coaxial and split-flow.

[0003] However, the current junction box of the reduction motor is generally bolted with small screws. Over time, the internal screws will rust. When using a screwdriver to disassemble, the groove on the top of the screw for disassembly will also be damaged under the torsional force of the screwdriver, resulting in the junction box cannot be opened smoothly.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 The utility model provides a technical solution: a reduction motor assembly, comprising a main body 1, a motor 2 is installed inside the main body 1, a reduction box 21 is installed on the right side of the motor 2, a junction box 3 is installed on the outer wall of the motor 2, the junction box 3 is divided into a top cover 31 and a base 32, a protrusion 33 and a recess 34 are provided in the top cover 31 and the base 32, an inner cavity 4 is provided inside the protrusion 33, an inner frame 5 is movably installed in the inner cavity 4, an inner bevel 51 is provided at the bottom of the inner frame 5, and a rectangular groove 52 is provided on the inner side of the inner frame 5, a groove 53 penetrating the outer wall is opened on the inner bevel 51, a spring 6 is installed in the middle of the inner frame 5, a plastic block 61 is installed at the bottom of the spring 6, an iron bead 62 is movably installed at the location of the groove 53, and a thimble 7 is provided at the recess 34.

[0024] The protrusion 33 and the recess 34 are symmetrically arranged at the four corners of the top cover 31 and the base 32, respectively, and the size of the protrusion 33 is smaller than the recess 34. The bottom of the inner cavity 4 is symmetrically provided with an outer bevel 41, and the outer bevel 41 and the inner bevel 51 are not arranged parallel to each other, and the rectangular groove 52 is symmetrically arranged on the inner wall of the inner frame 5. The top of the spring 6 is fixedly connected to the inner wall of the inner cavity 4, and the two ends of the plastic block 61 are embedded in the rectangular grooves 52 on the left and right sides. The iron bead 62 is symmetrically arranged between the plastic block 61 and the bottom of the inner frame 5, and the diameter of the iron bead 62 is greater than the inner diameter of the groove 53. The material of the inner frame 5, the spring 6 and the iron bead 62 are all iron, and the protrusion 33, the inner frame 5 and the plastic block 61 are all provided with a through hole 71 that penetrates the outer wall. The protrusion 33 and the through holes 71 in the inner frame 5 and the plastic block 61 are located on the same vertical line, and the top of the ejector pin 7 is set as a spherical arc surface. A slot 72 penetrating the outer wall is provided in the middle of the ejector pin 7 , and the diameter of the ejector pin 7 is smaller than the through hole 71 .

[0025] Working principle: When the top cover 31 and the base 32 in the junction box 3 are removed, the utility model places a strong magnet on the top cover 31. Since the inner frame 5, the iron bead 62 and the spring 6 are all made of iron, the magnet can absorb objects made of materials such as iron, cobalt and nickel. Therefore, the strong magnet will move the inner frame 5 and the iron bead 62 upward along the inner cavity 4 as a whole through absorption, and then the internal spring 6 will deform and compress to generate deformation force. The outer bevel 41 and the inner bevel 51 are designed to be non-parallel. During the upward movement of the inner frame 5, the gap between the outer bevel 41 and the inner bevel 51 will become larger and larger, and then the iron bead 62 in the middle will have enough space to move and become active. The iron bead 62, the outer bevel 41 and the slot 72 are separated, and the interaction force between the three can smoothly lift the slot 72 upward, and the ejector pin 7 can be smoothly pulled out of the inner cavity 4.

[0026] When installing the top cover 31, since the strong magnet is removed after disassembling the top cover 31, the inner frame 5 loses the magnetic adsorption effect of the magnet, and the inner frame 5 is subjected to the reverse deformation force of the spring 6, thereby moving to the bottom of the inner cavity 4, and aligning the protrusion 33 on the top cover 31 with the recessed part 34 and inserting it, and then the ejector pin 7 passes through the through hole 71 into the inner cavity 4. At the beginning, the ejector pin 7 is subjected to the force from the iron beads 62 on both sides, and the upper spring 6 will undergo a short deformation process. When the iron beads 62 move to the slot 72, the ejector pin 7 is restricted therein by the elastic force of the top spring 6 and the force of the iron beads 62 on both sides and the outer bevel 41, thereby fixing the top cover 31.
