Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts production, in particular to an auxiliary tightening mechanism for automobile parts production. Background Art

[0002] Auto parts are the various units that constitute the overall auto parts processing, as well as the products that serve the auto parts processing. They are necessary factors to support the sustainable and healthy development of the automobile industry. In the processing and production of auto parts, it is necessary to connect and assemble multiple components, which are generally fixed by bolts, welding, clamping, etc., and when fixed by bolts, they are generally fixed by twisting with an electric wrench.

[0003] When tightening bolts between automobile parts, the existing electric wrench provides rotational power through the driving motor of the electric wrench, and selects different sleeves at one end according to the different sizes of the bolts, so that the sleeves are sleeved on the surface of the bolts to tighten the bolts. However, different sleeves need to be selected when rotating bolts of different sizes, and the sleeves need to be constantly replaced, which affects the tightening and assembly efficiency of automobile parts.

[0004] Therefore, it is urgent to provide an auxiliary tightening mechanism for automobile parts production to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the disadvantages of the prior art and provide an auxiliary tightening mechanism for automobile parts production.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an auxiliary tightening mechanism for automobile parts production, including a mounting tank, a pushing assembly is installed on the outer wall of the mounting tank, a rotating handle is fixedly connected to the pushing assembly, and protective sleeves are fixedly connected on both sides of the outer wall of the rotating handle, a switching assembly is arranged on the outer wall of the mounting tank, a fixing assembly is arranged at the bottom of the inner wall of the mounting tank, and a plurality of second racks are fixedly connected to the bottom of the inner wall of the mounting tank.

[0007] The utility model is further configured as follows: the pushing assembly includes two connecting rods fixedly connected to the outer wall of the mounting tank, the inner sides of the two connecting rods are provided with mounting grooves, the inner walls of the two mounting grooves are fixedly connected with guide rods, the outer walls of the two guide rods are slidably connected with a first spring, the tops of the outer walls of the two guide rods are slidably connected with guide blocks, a pressing rod is fixedly connected between the inner walls of the two guide blocks, the bottom of the pressing rod is fixedly connected with a linkage rod, and the bottom of the linkage rod is fixedly connected with a pushing block.

[0008] Through the above technical solution, the pressing rod is first pressed so that the pressing rod drives the two guide blocks to slide downward. At the same time, the two guide blocks will squeeze the corresponding first springs, and the pressing rod will also drive the linkage rod to move downward, and then the linkage rod will drive the pushing block to move synchronously, thereby achieving the purpose of pushing.

[0009] The utility model is further configured as follows: the outer walls of the two guide rods are matched with the corresponding inner walls of the guide blocks, and the outer walls of the two guide blocks are matched with the corresponding inner walls of the installation grooves.

[0010] Through the above technical solution, the outer wall of the guide rod matches the inner wall of the guide block, so that the guide block can only slide along the axial direction of the guide rod, effectively avoiding lateral deviation or shaking of the guide block during movement. Similarly, the outer wall of the guide block fits with the inner wall of the installation groove, further constraining the movement of the guide block and ensuring that it moves in a straight line in the installation groove.

[0011] The utility model is further configured as follows: the switching assembly includes two mounting rings fixedly connected to the outer wall of the mounting tank, a replacement box is rotatably connected between the inner walls of the two mounting rings, a plurality of deep hole sleeves are rotatably connected to the inner wall of the replacement box, a plurality of first racks are fixedly connected to the outer walls of the plurality of deep hole sleeves, and an entrance is opened on the outer wall of the mounting tank.

[0012] Through the above technical solution, the replacement box is first rotated along the mounting ring so that the replacement box can drive the matching deep hole sleeve to move to the entrance, and then the mounting tank is appropriately tilted so that the deep hole sleeve can slide into the inner wall of the mounting tank through the entrance. When replacement is required, it is only necessary to slide the deep hole sleeve on the inner wall of the mounting tank into the replacement box through the entrance.

[0013] The utility model is further configured as follows: the first racks fixedly connected to the outer walls of the plurality of deep hole sleeves are all meshed with the second racks.

[0014] Through the above technical solution, the rotation angle of the deep hole sleeve can be accurately controlled. During the process of tightening the bolt, according to different tightening process requirements, the rotation angle of the deep hole sleeve can be accurately controlled through the movement of the second rack to ensure that the bolt reaches the specified tightening torque and tightening angle, thereby improving the tightening quality.

[0015] The utility model is further configured as follows: the fixing assembly includes two connecting grooves opened on the inner wall of the mounting tank, two sliding rods are slidably connected to one side of the inner wall of the two connecting grooves, the corresponding surfaces of the two groups of sliding rods are fixedly connected to fixing blocks, the opposite surfaces of the two groups of sliding rods are fixedly connected to pulling blocks, and the outer walls of multiple sliding rods are slidably connected to second springs.

[0016] Through the above technical solution, first pull the two pulling blocks so that the two pulling blocks drive the corresponding sliding rods to move outward. At the same time, the two sets of sliding rods will drive the corresponding fixed blocks to move inside the connecting groove until the deep hole sleeve fits with the second rack. Then, the two fixed blocks are reset by the second spring to achieve the purpose of fixation.

[0017] The utility model is further configured as follows: a plurality of the slide bars all penetrate the inner wall of the installation tank, and the tops of the two fixing blocks are both provided with bevel angles.

[0018] The above technical solution can be used as a track for the sliding rod to ensure that the sliding rod maintains linear motion during movement and avoids deviation or shaking. At the same time, the angled slope will decompose the downward pressure of the deep hole sleeve into a horizontal component force, so that the fixed block can automatically move into the connecting groove without the operator having to pull the pull block additionally. This simplifies the installation process of the deep hole sleeve and improves the installation efficiency.

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The utility model provides a replacement component, which enables the auxiliary tightening mechanism to quickly replace different tightening heads or adapters to meet the tightening requirements of different parts. The tightening head suitable for the corresponding cylinder head bolt can be quickly replaced, avoiding a lot of time spent on replacing equipment or adjusting parameters, greatly shortening the production preparation time, and enabling the production line to operate efficiently and continuously;

[0021] 2. The utility model can provide power support for the replacement process by setting a pushing component, so that different tightening parts can be quickly pushed to the working position, reducing the time for replacing components, thereby improving the efficiency of the entire production process.
