[0002] Reducers are a vital component widely used in mechanical transmission systems, primarily used to reduce speed and increase torque. Due to their complex structure and high precision requirements, the design and application of assembly fixtures are particularly important during the production and assembly of reducers. During assembly, existing reducers typically require fixtures to secure the reducer housing from both sides. However, subsequent assembly operations cannot be performed on these two clamped sides. The clamping must be released, the reducer housing must be adjusted, and the housing must be re-secured. This requires repeated disassembly and assembly, which in turn affects the assembly efficiency of the reducer. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] A speed reducer typically consists of multiple components, including gears, bearings, a housing, and input and output terminals. The precision and fit of each component directly impact the performance of the entire speed reducer. Therefore, during assembly, it is crucial to ensure that each component is accurately and stably positioned to achieve the desired assembly accuracy.

[0023] Example 1:

[0024] Based on the technical defects of low assembly efficiency in existing technology, please refer to Figure 1-Figure 4 The utility model provides an assembly fixture for a reducer, which can be used to assemble each side of the reducer casing. There is no need to disassemble and assemble the reducer casing back and forth, which improves the assembly efficiency of the reducer. The fixture includes a mounting plate 1, which is a three-dimensional structure. Both side walls inside the mounting plate 1 are equipped with clamping mechanisms 2 for fixing the reducer casing from four directions. The two groups of clamping mechanisms 2 are arranged in an upper and lower staggered manner; through the setting of the two groups of clamping mechanisms 2, first use one group of clamping mechanisms 2 to clamp and fix the two side walls of the reducer casing, and then assemble the four sides of the reducer casing. After assembly, release the clamping mechanism 2, and then use another group of clamping mechanisms 2 to clamp and fix the reducer casing, and then assemble the remaining two sides of the reducer casing.

[0025] To achieve the clamping and fixing of the reducer housing, please refer to Figure 3 The clamping mechanism 2 includes a mounting base 201 mounted on the inner wall of the mounting plate 1, and a motor 202 is sleeved on the mounting base 201. A gear 203 is fixed on the output shaft of the motor 202. The gear 203 is located between the two tooth plates 204 and meshes with them. A flip assembly 205 for rotating the reducer housing and performing assembly operations on each surface of the reducer is provided at one end of the two tooth plates 204 away from the gear 203. The motor 202 is used to drive the gear 203 to rotate, and the gear 203 is driven to move relative to the two tooth plates 204 through the meshing action, thereby clamping and fixing the reducer housing.

[0026] To facilitate the assembly of multiple surfaces of the reducer housing, please refer to Figure 3The flip assembly 205 includes a rotating shaft 2051 rotatably connected to the two tooth plates 204, and a splint 2052 is fixed at one end of the two rotating shafts 2051. The other end of one of the rotating shafts 2051 is fixedly connected to the output shaft of motor 2 2053. Motor 2 2053 is installed on a bracket 2054, and the bracket 2054 is fixed on the side wall of the tooth plate 204; the rotating shaft 2051 is driven to rotate by motor 2 2053, and the rotating shaft 2051 drives the splint 2052 to rotate, so that the fixed reducer housing can be rotated, and then the assembly side of the reducer housing can be switched.

[0027] To ensure the stability of the reducer housing, the four clamping plates 2052 are at the same level.

[0028] In order to improve the movement stability of the two tooth plates 204, a sliding sleeve 206 is embedded on the side walls of the two tooth plates 204, and the sliding sleeve 206 is mounted on the guide frame 207. The other end of the guide frame 207 is fixed to the inner wall of the mounting plate 1, and the other end is fixed to the side support plate 208. The side support plate 208 is fixed to the inner wall of the mounting plate 1; through the action of the sliding sleeve 206 and the guide frame 207, the tooth plate 204 will not shake when used horizontally, and the setting of the side bracket 2054 can fix the guide frame 207.

[0029] In order to facilitate the installation of the whole, a plurality of mounting holes are provided at the bottom of the mounting plate 1; the whole can be installed and fixed by means of bolts and other components.

[0030] Example 2:

[0031] When the reducer housing is being assembled, the parts need to be pressed into the interior of the reducer housing, which will generate downward pressure on the reducer housing. If the fixing force of the splint 2052 on the reducer housing is relied upon alone, a good fixing effect cannot be achieved. To solve this problem, a base 3 is installed at the bottom of the mounting plate, and four symmetrically distributed cylinders 4 are embedded on the base 3. A support plate 5 is fixed to the telescopic shafts of the four cylinders 4. When the reducer housing is being assembled, the cylinder 4 is used to drive the support plate 5 to move upward so that the support plate 5 contacts the bottom of the reducer housing, thereby providing support thereto, making the reducer more stable during assembly.

[0032] Through the above embodiment, it can be known that: under the action of the clamping mechanism 2, one group of clamping mechanisms 2 is first controlled to work, at this time, motor 1 202 drives gear 203 to rotate, and gear 203 drives the two tooth plates 204 to move relative to each other through meshing, thereby clamping and fixing the reducer housing, and then under the action of the flip assembly 205, motor 2 2053 is used to drive the rotating shaft 2051 to rotate, and the rotating shaft 2051 drives the clamping plate 2052 to rotate, so that the fixed reducer housing can be rotated, and then the assembly side of the reducer housing can be switched. During assembly, the cylinder 4 is used to drive the support plate 5 to move upward so that the support plate 5 contacts the bottom of the reducer housing, thereby providing support for it. After the four sides of the reducer housing are assembled, the clamping mechanism 2 is released, and another group of clamping mechanisms 2 is used to clamp and fix the reducer housing, and the remaining two sides of the reducer housing can be assembled.
