[0027] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] like Figure 1-Figure 6 As shown, this embodiment provides a frame accessory assembly tool, including an assembly tool body and an installation component, the assembly tool body is detachably installed on the frame through the installation component, and a plurality of accessory assembly positions 1 are provided on the assembly tool body, and the accessory assembly positions 1 are arranged in a one-to-one correspondence with the accessories to be assembled; the installation component includes a connecting member and a positioning member, the connecting member is used for detachably connecting the assembly tool body to the frame, and the positioning member is used for positioning the installation position of the assembly tool body on the frame, so that the position of the accessory assembly position 1 matches the installation position of the corresponding accessory to be assembled on the frame.

[0029] When in use, first install the assembling tool body on the frame through the connecting parts, and locate the installation position of the assembling tool body on the frame through the positioning parts, so that the accessory assembly position 1 on the assembling tool body matches the installation position of the corresponding accessory to be assembled on the frame, and then, assemble the accessory to be assembled according to the accessory assembly position 1 on the assembling tool body. After the accessories to be assembled on the frame are assembled, the assembling tool body can be removed.

[0030] It should be noted that the specific structure of the assembly tool body needs to be designed by those skilled in the art according to the actual frame structure. Since the frame usually includes a crossbeam and a side beam, the assembly tool body in this embodiment includes a crossbeam assembly tool and a side beam assembly tool. The crossbeam assembly tool is used to be set on the crossbeam of the frame to assemble the crossbeam accessories of the frame; the side beam assembly tool is used to be set on the side beam of the frame to assemble the side beam accessories of the frame.

[0031] It should be noted that, for the accessories to be assembled of the frame, such as pipe clamps, wire clamps, grounding sockets, wire pull sockets, etc., the design idea of ​​this embodiment is to use an assembly template to assemble the frame accessories. The assembly template is mainly for assembling two or more accessories distributed on the same plane of the frame. At the same time, the existing X-axis center line, Y-axis center line, Z-axis center line and hat tube center line on the frame are used as the alignment lines of the assembly template; specifically, the positioning part in this embodiment includes a positioning line (that is, the alignment line of the assembly template). When the positioning line coincides with the corresponding identification line on the frame, the assembly tool body (that is, the assembly template) completes the positioning on the frame.

[0032] It should be noted that, since the parts on the crossbeam of the frame where accessories need to be installed are mainly divided into the upper part of the crossbeam, the lower part of the crossbeam and the side part of the crossbeam, and the parts on the side beams of the frame where accessories need to be installed are mainly divided into the upper part of the side beam, the upper end surface of the side beam and the outer surface of the side beam, therefore, the crossbeam assembly tooling and the longitudinal beam assembly tooling in this embodiment are designed as assembly templates for partitioned production.

[0033] Specifically, in the present embodiment, the beam assembly tooling includes a first beam assembly template 2, a second beam assembly template 3 and a third beam assembly template 4, and the first beam assembly template 2, the second beam assembly template 3 and the third beam assembly template 4 are respectively detachably installed on the upper beam portion, the lower beam portion and the side beam portion of the frame through a group of installation components, and a plurality of accessory assembly spaces 1 are provided on the first beam assembly template 2, the second beam assembly template 3 and the third beam assembly template 4.

When in use, line A and line B are respectively aligned with the X-direction center line and the Y-direction center line of the frame to align the position of the first beam group to the template 2 on the beam of the frame, thereby completing the positioning of the first beam group to the template 2 on the beam of the frame.

[0035] The second beam group is for sample 3. Figure 2 As shown, Figure 2 Line A and line B in the figure serve as positioning lines for the second beam group to the template 3. Line A and line B are formed by a plurality of V-shaped grooves provided on the second beam group to the template 3. When in use, line A and line B are respectively aligned with the X-direction center line and the Y-direction center line of the frame to align the position of the second beam group to the template 3 under the beam of the frame, thereby completing the positioning of the second beam group to the template 3 under the beam of the frame.

[0036] The third beam group is for sample 4. Figure 3 As shown, Figure 3 Line A and line B in the figure are used as positioning lines for the third beam group to the template 4, wherein line A is the bottom edge line of the third beam group to the template 4, and line B is the middle docking line of the third beam group to the template 4. When in use, line A and line B are respectively aligned with the X-direction center line and the Y-direction center line of the side surface of the frame beam, and assisted by planes such as beam supports, the position of the third beam group to the template 4 on the side surface of the frame beam is aligned to complete the positioning of the third beam group to the template 4 on the side surface of the frame beam.

[0037] In the present embodiment, the side beam assembly tooling includes a first side beam assembly template 5, a second side beam assembly template 6 and a third side beam assembly template 7; the first side beam assembly template 5, the second side beam assembly template 6 and the third side beam assembly template 7 are respectively detachably installed on the upper side beam portion, the upper end portion of the side beam and the outer side portion of the side beam of the frame through a group of installation components, and a plurality of accessory assembly spaces 1 are provided on the first side beam assembly template 5, the second side beam assembly template 6 and the third side beam assembly template 7.

[0038] The first side beam assembly is for the template 5 as shown in Figure 4 As shown, Figure 4 Line A and line B in the figure serve as positioning lines for the first side beam assembly template 5, and line A and line B are formed by a plurality of V-shaped grooves provided on the first side beam assembly template 5. When in use, line A and line B are respectively aligned with the Y-direction center line and the center line of the cap tube on the side beam of the frame, and the position of the first side beam assembly template 5 on the upper part of the side beam of the frame is aligned, thereby completing the positioning of the first side beam assembly template 5 on the upper part of the side beam of the frame.

[0039] The second side beam group is for sample 6. Figure 5 As shown, Figure 5 Line A and line B in the figure are used as positioning lines for the second side beam assembly template 6, wherein line A is the bottom edge line of the second side beam assembly template 6, and line B is the right side edge line of the second side beam assembly template 6. When in use, line A and line B are respectively aligned with the Y-direction center line on the frame side beam and the edge line of the side beam end, and the circular hole on the second side beam assembly template 6 is aligned with the center hole of the side beam cap tube as an auxiliary alignment reference to align the position of the second side beam assembly template 6 on the upper end surface of the frame side beam, thereby completing the positioning of the second side beam assembly template 6 on the upper end surface of the frame side beam.

[0040] The third side beam assembly is for sample 7.
