DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0028] The specific embodiment of the utility model provides an assembled static platform of a large-scale heavy-load parallel robot, combined with the attached Figure 1 As shown, it mainly includes a first platform 1, a motor assembly mounting plate 2 and a second platform 3.

[0029] Among them, the first platform 1, the motor assembly mounting plate 2 and the second platform 3 are all plate-like structures. The various components of the plate-like structures can be stacked in a separated state, so that they only occupy a small transportation and storage space, thereby reducing transportation costs. One end of the motor assembly mounting plate 2 is detachably connected to the first platform 1, and the other end is detachably connected to the second platform 3. The various components are assembled in a detachable connection manner to form the main structure of the assembled static platform of the large heavy-load parallel robot. This structure is the main load-bearing structure. Therefore, the first platform 1, the motor assembly mounting plate 2 and the second platform 3 are all made of high-strength metal. The design method of each component being separated makes it easier for operators to transport and assemble the independent components, as compared with the entire main structure.

[0030] In another embodiment of the present application, Figure 2 As shown, the first platen 1 has at least two first mounting protrusions 4 in the circumferential direction, and the at least two first mounting protrusions 4 are centrally symmetrical with the center of the first platen 1. The first mounting protrusion 4 is used to connect with the motor assembly mounting plate 2. In this way, the first mounting protrusion 4 is arranged, and under the condition of ensuring the structural strength, a larger area of ​​the first platen 1 is not required. It should be noted that if the first platen 1 is designed to be circular, the first mounting protrusion 4 for connecting the motor assembly mounting plate 2 is set in the circular structure as a whole. At this time, the area of ​​the circular structure is larger than that of the attached Figure 2 The area in the middle is larger, the volume is larger, and the weight is heavier. Such a configuration indirectly reduces the volume of the first platform 1, thereby reducing its weight.

[0031] The second platen 3, which is the same as the first platen 1, has at least two second mounting protrusions 5 in the circumferential direction, and the at least two second mounting protrusions 5 are centrally symmetrical about the center of the second platen 3. The second mounting protrusions 5 are used to connect with the motor assembly mounting plate 2, and the same setting method is also to reduce the volume of the second platen 3, thereby reducing the weight.

[0032] It should be noted that the main load in this application is at the position of the motor assembly 6. The motor assembly 6 is arranged on the motor assembly mounting plate 2. The specific motor assembly 6 includes a motor and a reducer. The reducer is connected to the output shaft of the motor, and the reducer is connected to the motor assembly mounting plate 2. The motor assembly mounting plate 2 is arranged on the first platform 1, and the first platform 1 is the main load-bearing part. Therefore, the width of the first mounting protrusion 4 is larger and the connection strength is greater, and the second platform 3 can be designed to be narrower, which not only ensures the connection but also reduces the weight to a certain extent.

[0033] In another embodiment of the present application, the number of motor assembly mounting plates 2 is designed to be at least two, and the number can also be three, four, five, six, seven, eight, etc., and the corresponding first mounting protrusions 4 and second mounting protrusions 5 also correspond thereto.

[0034] In the specific embodiments of the present application, Figure 4 As shown, a portion of the end surface of the motor assembly mounting plate 2 for connecting the motor assembly 6 is concave, and the concave design can also reduce weight. The thickness of the end of the motor assembly mounting plate 2 connected to the first platform 1 is greater than the local thickness, so that the connection structure strength between the first platform 1 and the motor assembly mounting plate 2 is greater, thereby ensuring that the structural strength of the assembled static platform of the large heavy-load parallel robot is greater. The thickness of the two side ends of the motor assembly mounting plate 2 gradually decreases from the end close to the first platform 1 to the end close to the second platform 3. While ensuring the connection strength, the volume is further reduced, thereby reducing the weight.

[0035] In a specific embodiment of the present application, both the first platform 1 and the second platform 3 are perpendicular to the motor assembly mounting plate 2 and are connected by bolts 7. The number of bolts 7 connecting the first platform 1 and the motor assembly mounting plate 2 is greater than the number of bolts 7 connecting the second platform 3 and the motor assembly mounting plate 2, so that the connection strength between the first platform 1 and the motor assembly mounting plate 2 is greater, ensuring that the assembled static platform of the large heavy-load parallel robot can carry a larger load.

[0036] Specifically, threaded holes 8 are provided at both ends of the motor assembly mounting plate 2 for connecting with the first platform 1 and the second platform 3 respectively. For this purpose, mounting holes 9 are provided at the positions corresponding to the threaded holes 8 on the first platform 1 and the second platform 3, and bolts 7 pass through the mounting holes 9 and are threadedly connected with the threaded holes 8; a positioning pin 10 is provided on the end surface where the motor assembly mounting plate 2 is connected to the first platform 1, a positioning pin 10 is provided on the motor assembly mounting plate 2, and a positioning hole 11 is provided on the first platform 1, and the positioning pin 10 is passed through the positioning hole 11. The positioning pin 10 and the positioning hole 11 are arranged in such a manner that preliminary positioning can be performed before tightening the bolt, so as to ensure that the subsequent bolt installation is smoother. The number of the positioning pins 10 is at least two, so that it can be ensured that the first platform 1 and the motor assembly mounting plate 2 will not move relative to each other during installation.

[0037] In the specific embodiment of the present application, it also includes a motor assembly 6, a motor assembly shell 12 and a table shell 13. The motor assembly 6 is a driving component of the manipulator. The motor assembly mounting plate 2 has a setting hole 14. The reducer output end of the motor assembly 6 is partially located in the setting hole 14 and can be used to connect the manipulator. The motor assembly 6 is fixed to the motor assembly mounting plate 2 by bolts 7. The motor assembly shell 12 is covered on the motor assembly 6 and snapped onto the motor assembly mounting plate 2. The motor assembly shell 12 protects and decorates the motor assembly 6. The table shell 13 is arranged between the first table 1 and the second table 3. The table shell 13 is a plurality of shells arranged around the first table 1 and the second table 3. The motor assembly shell 12 and the table shell 13 are used to cover the external leakage structure, making the structure more integrated and beautiful.

[0038] The specific motor assembly shell 12 includes an upper shell 15 and a lower shell 16. The upper shell 15 is covered above the motor assembly 6. The top surface of the upper shell 15 is flush with the top surface of the first platform 1. The lower shell 16 is covered below the motor assembly 6. The lower shell 16 is covered on the second platform 3. The upper shell 15 and the lower shell 16 are interlocked to form an overall shell structure that wraps the motor assembly 6. The upper shell 15 and the lower shell 16 are connected in a detachable manner to facilitate later maintenance or repair of the motor assembly 6 inside. The upper shell 15 and the lower shell 16 can be connected by bolts or snap-on connections.

[0039] The motor assembly shell 12 and the table shell 13 are both plastic shells, which makes the overall structure lighter and more convenient to transport.
