Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooling bracket technology, and in particular to a bracket for final assembly. Background Technology
[0002] A gearbox is a transmission device based on a planetary gear train structure. It achieves a reduction in transmission ratio and an amplification of torque through the meshing of the sun gear, planet gears, and internal gear ring.
[0003] Typically, all bolts on a gearbox need to be marked with anti-loosening marks. If a bolt becomes loose, the mark will break, allowing workers to quickly identify and tighten the loose bolt, minimizing the potential risk. Previously, marking anti-loosening marks required using an overhead crane and slings to lift the gearbox. Operators had to work at the bottom of the gearbox, posing a risk of head injuries from head injuries. A broken sling could also damage the gearbox and cause serious injury to the operator. Furthermore, an overhead crane could only lift one gearbox at a time, preventing simultaneous operation of multiple gearboxes. Compared to a final assembly bracket, an overhead crane is significantly more expensive. Adding an overhead crane to allow simultaneous operation of multiple gearboxes would increase the cost per gearbox by approximately 20 times compared to a final assembly bracket.
[0004] Therefore, it is necessary to design a completely new final assembly bracket to facilitate support when marking the gearbox bolts with anti-loosening marks. Utility Model Content
[0005] The purpose of this invention is to provide a final mounting bracket.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A final assembly bracket includes a left support and a right support, both of which are isosceles triangles. Each of the left and right supports has two symmetrically distributed adjustable support seats on its base beam. Two parallel left support crossbeam inserts are fixed to the inner side of the base beam of the left support, and two parallel right support crossbeam inserts are fixed to the inner side of the base beam of the right support. The opposing left and right support crossbeam inserts are inserted from the left and right ends of a hollow crossbeam, respectively. The left and right support crossbeam inserts are fixed to the crossbeam using fasteners. A gearbox safety stop support rod is located next to the crossbeam.
[0008] Furthermore, one left support beam insert is fixedly connected to one end of the bottom beam of the left support, and the other left support beam insert is fixedly connected to the middle of the bottom beam of the left support.
[0009] Furthermore, one right support beam insert is fixedly connected to one end of the bottom beam of the right support, and the other right support beam insert is fixedly connected to the middle of the bottom beam of the right support.
[0010] Furthermore, the height of the gearbox safety stop support rod is adjustable.
[0011] Furthermore, the top of the gearbox safety stop support rod is provided with a tray with a U-shaped longitudinal section for supporting the gearbox safety stop.
[0012] Furthermore, both the left and right supports are provided with brackets at their tops, and two support rollers are symmetrically arranged on the brackets. The axial direction of the support rollers is parallel to the length direction of the crossbeam.
[0013] Furthermore, rectangular through holes are provided on the sides of the left and right support beam inserts, and rectangular through holes are also provided on the side of the beam. At least one fastener passes through the rectangular through holes on the left and right support beam inserts and the beam to fix them together, and at least one fastener passes through the rectangular through holes on the right and right support beam inserts and the beam to fix them together.
[0014] Furthermore, the insertion depth of the left and right support beam inserts in the beam can be adjusted by adjusting the fixing position of the fasteners.
[0015] Compared with the prior art, the outstanding advantages of this utility model are:
[0016] The final assembly bracket of this utility model can provide support when marking anti-loosening marks on gearbox bolts. Moreover, the bracket can be adjusted in both height and length directions, making it suitable for various types of gearboxes and operators of all heights. It is safe and convenient to use.
[0017] The final assembly bracket of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0021] like Figure 1As shown, a final assembly bracket includes a left support 1 and a right support 2, both of which are isosceles triangles. Each of the bottom beams of the left support 1 and the right support 2 has two symmetrically distributed adjustable support seats 3. Two parallel left support beam inserts 11 are fixed to the inner side of the bottom beam of the left support 1, and two parallel right support beam inserts 21 are fixed to the inner side of the bottom beam of the right support 2. The opposing left and right support beam inserts 11 and 21 are inserted from the left and right ends of a hollow beam 4, respectively, and are fixed to the beam 4 by fasteners 5. Specifically, one beam 4 is used to fix the support beam inserts at the ends of the bottom beams of the two supports, and the other beam 4 is used to fix the support beam inserts in the middle of the bottom beams of the two supports. A gearbox safety stop support rod 6 is provided next to the beam 4 connecting the support beam inserts in the middle of the bottom beams of the two supports.
[0022] One left support beam insert 11 is fixedly connected to one end of the bottom beam of the left support 1, and the other left support beam insert 11 is fixedly connected to the middle of the bottom beam of the left support 1. One right support beam insert 21 is fixedly connected to one end of the bottom beam of the right support 2, and the other right support beam insert 21 is fixedly connected to the middle of the bottom beam of the right support 2.
[0023] The height of the gearbox safety stop support rod 6 is adjustable. The top of the gearbox safety stop support rod 6 is equipped with a U-shaped tray to support the gearbox safety stop.
[0024] Both the left support 1 and the right support 2 are equipped with brackets at their tops, and two support rollers 7 are symmetrically arranged on the brackets. The axial direction of the support rollers 7 is parallel to the length direction of the crossbeam 4. The support rollers 7 are made of nylon.
[0025] The left support beam insert 11 and the right support beam insert 21 have rectangular through holes on their sides, and the side of the beam 4 also has a rectangular through hole. Two fasteners 5 pass through the rectangular through holes on the left support beam insert 11 and the beam 4 to fix them together, and two fasteners 5 pass through the rectangular through holes on the right support beam insert 21 and the beam 4 to fix them together. By adjusting the fixing position of the fasteners 5, the insertion depth of the left support beam insert 11 and the right support beam insert 21 in the beam 4 can be adjusted, thereby accommodating gearbox shafts of different lengths.
[0026] The height of each of the four adjustable support bases 3 is adjustable, which can be used to adjust the overall height of the tooling to accommodate different gearboxes and users of different heights.
[0027] The final assembly bracket is in use as follows: Figure 2As shown, the two support rollers 7 of the left support 1 and the two support rollers 7 of the right support 2 respectively support the two ends of the gearbox shaft 8, and the top tray of the gearbox safety stop support rod 6 supports the safety stop of the gearbox 9.
