[0039] In this embodiment, as Figure 3 shown, the lifting member 2 includes a lifting rod 21 passing through the lifting bracket 11, and mounting plates 22 and connecting plates 23 are respectively connected to both ends of the lifting rod 21.

[0040] In this embodiment, as Figure 5 shown, the tool adapter 3 is fixed to the mounting plate 22 and includes a fixing plate 31 and a clamping plate 32 connected to the fixing plate 31 by fasteners (not shown).

[0041] In this embodiment, as Figure 4 shown, the transmission counterweight portion 4 includes a counterweight block 41, a pulley 42 and a transmission rope 43. The counterweight block 41 is sleeved in the counterweight rod 13, the pulley 42 is rotatably connected to the transmission rod 12, and both ends of the transmission rope 43 are respectively fixed to the counterweight block 41 and the connecting plate 23 and sleeved on the pulley 42 so that the counterweight block 41 drives the lifting member 2 to rise through the pulley 42 and the transmission rope 43 during the descending process.

[0042] In this embodiment, the weight of the counterweight block 41 is greater than the sum of the weights of the lifting member 2, the tool adapter 3 and the assembly tool 6 in the initial state.

[0043] In this embodiment, when the weight of the counterweight 41 increases or decreases, the lifting member 2 is driven to rise or fall in the lifting bracket 11 through the cooperation of the transmission rope 43 and the pulley 42.

[0044] In this embodiment, during the rising or falling process of the lifting member 2, it moves away from or enters the lifting groove.

[0045] In this embodiment, avoidance grooves 15 for avoiding the pulley 42 and the transmission rope 43 are provided on the same side of the lifting bracket 11 and the fixing plate 22.

[0046] In this embodiment, the traveling part 5 is a plurality of traveling wheels provided at various corner positions at the bottom of the base plate 1.

[0047] The characteristics and functions of the present utility model are further understood through the following description.

[0048] This embodiment provides an auxiliary device for improving assembly efficiency, which mainly includes: a base mechanism, a lifting mechanism, a transmission and counterweight mechanism, a traveling mechanism, a tool adapter mechanism, a tightening tool, etc. The main materials used for manufacturing are: common materials such as plates, round steel, and casters. The entire auxiliary device is made through processes such as welding and assembly.

[0049] The base mechanism (i.e., the base 1 and the lifting bracket 11, the transmission rod 12, and the counterweight rod 13 integrated on the base 1) designs the most reasonable base structure and design dimensions according to the environment of the assembly site and the characteristics of the purpose to be achieved by the entire auxiliary device. After ingenious design, the base mechanism is finally designed. The base mechanism should be able to carry other mechanisms, enable other mechanisms to operate organically, and ultimately enable the entire auxiliary device to achieve its purpose.

[0050] The lifting mechanism (i.e., the lifting member 2 and the lifting bracket 11). During the tightening process of the bolts assembled from bottom to top, the tightening tool (i.e., the assembly tool 6) needs to move up and down. The tightening tool is fixed to the lifting mechanism to meet the need for the up and down movement of the tightening tool.

[0051] The transmission and counterweight mechanism (i.e., the transmission counterweight part 4). The transmission and counterweight mechanism can balance the weight of the tightening tool and change the movement direction of the tightening tool when no external force is applied. Thereby improving the man-machine engineering of the worker's operation and reducing the force on the worker during operation.

[0052] The traveling mechanism (i.e., the traveling part 5). During the tightening process of the bolts, it is often necessary to tighten a group of bolts, and the auxiliary device needs to continuously change the operation position. The traveling mechanism solves the need for tightening bolts at different positions. Greatly expanding the use area of this auxiliary device.

[0053] Tool adapter and fixing mechanism (i.e., tool adapter 3). For different tightening tools, different adapter and fixing mechanisms are designed so that the tightening tools can form an organic whole with the entire auxiliary device.

[0054] The working method of the auxiliary device in this embodiment is as follows:

[0055] Step 1: Before operation, first adjust the counterweight so that the weight of the counterweight is slightly greater than the weight of the tool. In this way, without external force, the tool is always at the highest point. (This step only needs to be adjusted once for each).

[0056] Step 2: When tightening the bolt, first use your hand to press down the tool, and then align the first bolt with the socket and the bolt. After alignment, start the tool to tighten. (During the tightening process, as long as the hand keeps the tool in the starting state, there is no need to overcome the weight of the tool)

[0057] Step 3: After tightening the first bolt, move the entire device under the second bolt and repeat Step 2.

[0058] Step 4: Repeat Steps 2 and 3 in this way until the 4 bolts are tightened.

[0059] Step 5: Enter the process of tightening the next set of bolts.

[0060] The specific operation method of the auxiliary device in this embodiment is actually to drive the lifting member 2 to descend or ascend through the cooperation of the pulley 42 and the transmission rope 43 by reducing or increasing the weight of the counterweight block 41. During the ascending process of the lifting member 2, the assembly tool 6 is aligned with the position to be assembled until the assembly tool 6 is docked with the part to be assembled, and then the assembly tool 6 can be operated to install the part to be assembled. The assembly position is changed through the traveling wheels.

[0061] In summary, the auxiliary device of the present invention is composed of the combination of the base, the lifting member and the transmission counterweight part, constituting a reliable, practical and simple auxiliary device for assembly. The main application scenario is for the bottom of the vehicle frame, where the bolts are tightened from bottom to top and the operation space is extremely limited. Using this device can improve the ergonomics of workers, reduce the labor intensity of workers, and thus improve the assembly efficiency.
