Abstract
Description
Technical Field
[0001] The utility model relates to a joint module production device, in particular to a joint module assembly test device. Background Art
[0002] Joint modules are mostly used in the joints of robots, especially collaborative robots. Due to their structural and shape limitations, the shell of the joint module is generally designed as a rotating body structure, which mainly has two shapes: straight cylinder and T-type. Therefore, in the production process of the joint module, it is difficult to clamp and fix its shell, and the clamping and fixing of the shell directly affects the assembly quality of the joint module, because the shell, as a key connecting part, is the mounting base for reducers, motors, brakes, control panels and other parts. There is also an external connection structure on it for external installation of the joint module. There are also multiple installation benchmarks inside, which are important parts to ensure the installation quality of the joint module and the accuracy of test data. Therefore, the clamping and fixing of the shell of the joint module in the assembly process is particularly important.
[0003] like Figure 1 and Figure 2 As shown, the T-shaped shell 1 of the joint module includes a first straight-through end 11 and a second straight-through end 12 whose center lines are located in the same straight line, and a connecting end 13 whose center line is perpendicular to the straight line and is located in the middle between the first straight-through end 11 and the second straight-through end 12, and the connecting end 13 is provided with a plurality of screw holes evenly distributed along the circumference.
[0004] In the process of assembling the joint module using the above-mentioned T-shaped shell 2, the traditional method of clamping the T-shaped shell 1 is to fix it on the workbench with a clamping component so that the center line of the first straight end 11 and the center line of the second straight end 12 are both on the same horizontal straight line. This method has the following defects: during the assembly process, it is necessary to load the parts from the first straight end 11 and the second straight end 12 respectively, and there are certain requirements for their installation accuracy, so the assembly operation is inconvenient and the assembly efficiency is low. If the first straight end 11 or the second straight end 12 is upward, the assembly efficiency and accuracy can be improved, but the staff needs to use different clamping and fixing components to re-clamp and fix the shell for many times, which is not only time-consuming and labor-intensive, but also has greater positioning difficulty and lower efficiency. And the test work after assembly requires the joint module to remain in a horizontal state. Therefore, the traditional method of clamping the T-shaped shell 1 cannot achieve the effect of efficient and accurate assembly and testing, which reduces the production efficiency and quality of the joint module. Utility Model Content
[0005] The purpose of the utility model is to provide a joint module assembly and testing device that can be assembled and tested efficiently and accurately in order to solve the above-mentioned problems.

The two parallel cross bars of the horizontal "C"-shaped positioning rod can be respectively placed on the horizontal planes of the two "L"-shaped steps and are respectively in contact with the vertical planes of the two "L"-shaped steps. The vertical plane of the "L"-shaped step, the mounting seat vertical plane and the center line of the mounting hole of the mounting seat are parallel to each other. The rotating connector further includes a limiting plate. The planes where the two limiting plates are located are in the same virtual plane. The two limiting plates are respectively arranged on the opposite sides of the rotating seat and are parallel to the connecting plate. The distance between the limiting plate and the connecting plate is greater than the vertical height of the two parallel cross bars of the "C"-shaped positioning rod and satisfies the following conditions: when the two parallel cross bars of the "C"-shaped positioning rod respectively pass through the gaps between the two limiting plates and the connecting plate and are in contact with each other, the plane where the connecting plate is located is horizontal. When the plane where the connecting plate is located rotates with the rotating seat and is in the vertical direction, the corresponding surface of the connecting plate is simultaneously in contact with the mounting seat vertical planes on the same side of the two mounting seats.
[0009] Preferably, in order to facilitate the application of the device to the assembly and testing of joint modules of different sizes, the joint module assembly and testing device further includes an adapter plate.

[0027] As Figure 1-Figure 7 shown, the present utility model also discloses the following various more optimized specific structures:
[0028] In order to more accurately implement the function of the rotating seat 43 being in three temporary stable states, on the outer walls of the opposite sides of the mounting seat 23, there are respectively provided a pair of parallel mounting seat vertical planes 24.

The two limiting plates 44 are respectively arranged on the opposite sides of the rotating seat 43 and are parallel to the connecting plate 42. The distance between the limiting plate 44 and the connecting plate 42 is greater than the vertical height of the two parallel cross bars of the "C"-shaped positioning rod 3 and satisfies the following condition: when the two parallel cross bars of the "C"-shaped positioning rod 3 respectively pass through the gaps between the two limiting plates 44 and the connecting plate 42 and are in contact with each other, the plane where the connecting plate 42 is located is horizontal. When the plane where the connecting plate 42 is located is vertical as the rotating seat 43 rotates, the corresponding surface of the connecting plate 42 is simultaneously in contact with the mounting seat vertical planes 24 on the same side of the two mounting seats 23.

At this time, the corresponding surface plane of the connecting plate 42 is simultaneously in contact with the mounting seat vertical plane 24 on one side of the two mounting seats 23, and the T-shaped housing 1 is in a temporarily stable state, as Figure 8 shown. At this time, the parts in the T-shaped housing 1 close to the second straight-through end 12 can be assembled; after the parts in the T-shaped housing 1 close to the second straight-through end 12 are assembled, rotate the T-shaped housing 1 so that its first straight-through end 11 is vertically upward. At this time, the corresponding surface plane of the connecting plate 42 is simultaneously in contact with the mounting seat vertical plane 24 on the other side of the two mounting seats 23, and the T-shaped housing 1 is in a temporarily stable state, as Fig. 9 shown. At this time, the parts in the T-shaped housing 1 close to the first straight-through end 11 can be assembled; after the parts in the T-shaped housing 1 close to the first straight-through end 11 are assembled, the entire assembly process is completed. Then rotate the T-shaped housing 1 so that the center lines of its first straight-through end 11 and second straight-through end 12 are both horizontal, and then place the two mutually parallel cross bars of the "C"-shaped positioning rod 3 on the horizontal planes of the two "L"-shaped steps 22 and be in contact with the vertical planes of the two "L"-shaped steps 22 respectively. At the same time, make the two mutually parallel cross bars of the "C"-shaped positioning rod 3 pass through the gaps between the two limiting plates 44 and the connecting plate 42 and be in contact with each other.
