[0002] At present, new energy vehicles are developing rapidly. The battery pack in the power battery is the core of new energy vehicles. The battery pack provides power drive for the whole vehicle through the envelope of the upper and lower shells. The upper and lower battery box shells achieve installation sealing through the internal bushings and ensure the sealing safety of the internal core group. Most of the installation tools for the bushings on the upper shell of existing new energy battery boxes are manual tools such as rubber hammers. For example, the installation tool for the C-shaped bushing in the existing technology at present includes structures such as an upper handle, a lower handle, a handle bolt, a guide rod, an upper positioning pin, a lower positioning pin, and a magnetic rod. Among them, the upper and lower handles are connected in a cross form by bolts, and a guide rod is installed above the upper and lower positioning pins. Its working principle is to place the C-shaped bushing on the upper positioning pin, the magnetic rod adsorbs the bushing, place the lower positioning pin into the flange hole of the electric vehicle shell, and manually hold the upper and lower handles tightly, so that the top end of the lower handle contacts and presses down the guide rod, driving the upper positioning pin to press the bushing into the flange hole.

[0003] This kind of tool has certain disadvantages. The main problem is that there is only one bolt (and it is the stress point) connecting the two components of the upper and lower handles, the connection strength is weak, it is easy to loosen and damage during use, there is also a risk of pinching hands during the movement of the upper and lower handles, and the installation tool is manually operated, resulting in high labor intensity and low labor efficiency of personnel. On this basis, although an installation tool with a slightly higher degree of automation has been developed, there are problems of unstable installation and inflexible movement of the upper positioning pin during its use.

[0004] The main purpose of the utility model is to provide an installation tool for installing a C-shaped bushing, which adopts a pneumatic mode to improve work efficiency, and is a split-structured part with convenient replacement of components, a relatively stable working process, and a relatively high qualified rate of product installation.

[0005] To achieve the above object, the utility model provides an installation tool for installing a C-shaped bushing, which includes a cylinder, an upper positioning pin mechanism, a lower positioning pin mechanism, a first inverted U-shaped bracket, a second inverted U-shaped bracket, a third inverted U-shaped bracket, a pneumatic valve body, and a handle. The upper positioning pin mechanism includes an upper positioning pin, a magnetic rod, an upper spring, an internal and external thread nut bushing, an upper copper sleeve, and a guide tube. The lower positioning pin mechanism includes a lower positioning pin, a lower spring, a spring pressing plate, a lower copper sleeve, and a fixing bolt. The first inverted U-shaped bracket, the second inverted U-shaped bracket, and the third inverted U-shaped bracket are connected by fixing bolts to form a C-shaped structure, and the cylinder is fixed on the upper end surface of the second inverted U-shaped bracket.

[0006] Further, a pneumatic button is provided above the upper end of the pneumatic valve body and above the second inverted U-shaped bracket.

[0007] Furthermore, two valve body fixing hoops are provided at the upper end of the pneumatic valve body, and the pneumatic valve body is mounted on the lower end surface of the second inverted U bracket through the valve body fixing hoops.

[0008] Furthermore, a plurality of weight-reducing holes are provided on the lower end surface of the second inverted U bracket.

[0009] Furthermore, the handle is connected to the rear end of the second inverted U bracket through bolts.

[0010] Furthermore, the spring pressure plate is installed on the lower end surface of the third inverted U bracket through a pressure plate bolt.

[0011] Furthermore, the piston rod at the lower end of the cylinder passes through the second inverted U bracket, and a copper sleeve is provided between the two.

[0012] Furthermore, the upper spring is fixed between the inner and outer nut sleeves and the upper copper sleeve, and the inner and outer nut sleeves, the upper spring and the upper copper sleeve are placed in the guide tube in sequence from top to bottom.

[0013] Through the above technical solution, the beneficial effects of the utility model include: the installation tool of the utility model is more stable when installing the C-type bushing during use, the movement between the upper and lower locating pins is more flexible, and a copper sleeve structure is embedded between the second inverted U bracket and the cylinder, as well as in the upper locating pin mechanism and the lower locating pin mechanism, which can effectively reduce the friction resistance of movement between components. In addition, the upper locating pin mechanism and the lower locating pin mechanism are respectively provided with an upper spring and a lower spring, which effectively buffer the thrust generated during the operation of the cylinder, thereby reducing the impact force on the flange hole of the battery shell and reducing the risk of hole cracking.

[0042] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] like Figure 1As shown in the figure, it is a schematic structural diagram of the product of the present utility model. The present utility model is an installation tool for installing a C-shaped bushing, which is provided with a cylinder 1, an upper positioning pin mechanism, a lower positioning pin mechanism, a first inverted U-shaped bracket 4, a second inverted U-shaped bracket 5, a third inverted U-shaped bracket 6, a pneumatic valve body 7 and a handle 8. The first inverted U-shaped bracket 4, the second inverted U-shaped bracket 5 and the third inverted U-shaped bracket 6 are connected by fixing bolts 35 to form a U-shaped structure. The cylinder 1 is fixed on the upper end face of the second inverted U-shaped bracket 5. Specifically, as Figure 3 described, the piston rod 11 at the lower end of the cylinder 1 passes through the second inverted U-shaped bracket 5, and a copper bushing 12 is provided between the two, that is, the copper bushing 12 is located inside the second inverted U-shaped bracket 5. Then, the outer end of the piston rod 11 of the cylinder 1 passes through the copper bushing 12 and is fixed on the second inverted U-shaped bracket 5. The lower end face of the second inverted U-shaped bracket 5 is provided with a number of weight-reducing holes (not shown in the figure). In addition, a pneumatic button 71 is provided at the upper end of the pneumatic valve body 7 and above the second inverted U-shaped bracket 5. Two valve body fixing hoops 72 are provided at the upper end of the pneumatic valve body 7. The pneumatic valve body 7 is installed on the lower end face of the second inverted U-shaped bracket 5 through the two valve body fixing hoops 72. Pressing the pneumatic button 71 can control the start and stop of the cylinder 1. The handle 8 is connected to the rear end of the second inverted U-shaped bracket 5 by bolts.

[0044] As Figure 2 shown, the upper positioning pin mechanism of the present utility model is provided with an upper positioning pin 21, a magnetic rod 22, an upper spring 23, an internal and external thread nut sleeve 24, an upper copper sleeve 25 and a guide tube 26. Among them, the magnetic rod 22 passes through the upper positioning pin 21 horizontally. The upper spring 23 is fixed between the internal and external thread nut sleeve 24 and the upper copper sleeve 25. The internal and external thread nut sleeve 24, the upper spring 23 and the upper copper sleeve 25 are sequentially fixed in the guide tube 26 from top to bottom. The upper positioning pin 21 is located below the upper copper sleeve 25. Combining Figure 1 shown, the upper end of the upper positioning pin mechanism of the present utility model is fixedly connected to the piston rod 11 of the cylinder 1 by a nut. After starting the cylinder 1, the piston rod 11 extends out, and then presses the upper positioning pin mechanism to move downward (please refer to this process in Figure 4 and Figure 5 shown). A C-shaped bushing 9 is sleeved on the upper positioning pin 21 of the upper positioning pin mechanism. The C-shaped bushing 9 is attracted by the magnetic rod 22 and will not fall off.

[0045] Please also refer to Figure 1 、 Figure 4 and Figure 5As shown, the lower positioning pin 31 mechanism of the utility model is provided with a lower positioning pin 31, a lower spring, a spring pressure plate 33, a lower copper sleeve and a fixing bolt 35, wherein the lower spring and the lower copper sleeve are not indicated in the figure. Specifically, the lower end of the lower positioning pin 31 is connected to the lower spring, the lower copper sleeve is sleeved on the third inverted U bracket 6, and the lower positioning pin 31 passes through the lower copper sleeve and is connected to the lower spring, and the lower end of the lower spring abuts against the inner side surface of the spring pressure plate 33, and the spring pressure plate 33 is installed on the lower end surface of the third inverted U bracket 6 through the pressure plate bolt 331.

[0046] During use of the installation tool of the present invention, first place the C-type bushing 9 on the upper positioning pin 21, use the adsorption force of the magnetic rod 22 to prevent the C-type bushing 9 from falling, place the lower positioning pin 21 at the bushing mounting hole position of the battery upper shell, press the pneumatic button 71, and the cylinder valve body 7 controls the piston rod 11 of the cylinder 1 to move downward. Through the push of the piston rod 11, the upper and lower positioning pins 21 and 31 cooperate to install the C-type bushing 9 into the bushing mounting hole of the upper shell. After the fixation is completed, release the pneumatic button 71, the piston rod 11 of the cylinder 1 retracts, and the upper positioning pin 21 withdraws, and the installation of the C-type bushing 9 is completed safely and smoothly.

[0047] In addition, the existing C-type bushing installation tool has a main body made of cast iron, which is a split type and is prone to rust due to the properties of the material. The tightness of the connection and the effective service life are difficult to guarantee. If the main body is divided into two parts, due to its special shape, the entire part needs to be scrapped after damage, and the processing is difficult, and the investment cost becomes high. The C-type bushing installation tool of the present invention has a main body made of aluminum structure, which is lighter. The locking structure is connected by multiple bolts, and the tightness is guaranteed. The main body is split, the parts are easy to replace, and the subsequent maintenance is more convenient.

[0048] Through the above technical solution, the beneficial effects of the utility model include: the installation tool of the utility model is more stable in installing the C-type bushing 9 during use, the movement between the upper and lower locating pins 31 is more flexible, and a copper sleeve structure is embedded between the second inverted U bracket 5 and the cylinder 1, as well as in the upper locating pin mechanism and the lower locating pin 31 mechanism, which can effectively reduce the friction resistance of movement between components. In addition, an upper spring 23 and a lower spring are respectively provided in the upper locating pin mechanism and the lower locating pin 31 mechanism, which effectively buffer the thrust generated during the operation of the cylinder 1, thereby reducing the impact force on the flange hole of the battery shell and reducing the risk of hole cracking.

[0049] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
