Description

A pin sleeve tooling

technical field

The utility model relates to the field of automobile engines, in particular to a pin sleeve frock. 

Background technique

At present, a hammer is often used to knock the pin sleeve into the hole by continuously tapping the fixed pin sleeve. During the installation process, due to the uneven force of the hammer, it is prone to deformation, stuck in the hole and cannot enter the hole smoothly, and cannot meet the positioning requirements. Therefore, the pin sleeve must be taken out and a new pin sleeve must be installed. The loss is large, and the repetitive work of the workers is greatly increased, which reduces the production efficiency.

Chinese Patent Authorization Announcement No.: CN 102501061A, authorized announcement date on June 20, 2012, discloses a vehicle frame positioning pin sleeve press-fitting device, which relates to equipment for assembling vehicle frame positioning pin sleeves. The invention includes a support composed of a panel and two side support plates, a power cylinder with a piston rod, a push rod connected to the front end of the piston rod, a front fixing plate and a rear fixing plate respectively connected to both ends of the power cylinder, the The front fixing plate and the rear fixing plate are respectively fixed on the underside of the panel and the inner side of a side support plate. The disadvantage is that the press is driven by a cylinder, has a complex structure, and has high production and use costs. the

Utility model content

The utility model aims to overcome the disadvantages of the existing technology that the pin sleeve is easily deformed when the pin sleeve is installed, resulting in the waste of the pin sleeve due to inaccurate positioning, and provides a device that can make the pin sleeve receive uniform force, accurate positioning, and has a relatively simple structure. Pin sets tooling. the

In order to achieve the above object, the utility model adopts the following technical solutions:

A pin sleeve tooling of the utility model comprises a guide sleeve, a through hole is provided in the center of the guide sleeve, and an impact rod and a pressure rod that can slide up and down relative to the through hole are arranged in the through hole, and the impact rod The lower end of the lower end is fixedly connected with the upper end of the pressure rod, and the lower end of the pressure rod is covered with a pin sleeve. The impact rod and the pressure rod are in clearance fit with the through hole of the guide sleeve, and the impact rod and the pressure rod can slide in the through hole. The impact rod and the pressure rod are fixedly connected to ensure that both are fastened. The pin sleeve is located at the lower end of the pressure rod. When the impact rod is pushed, the impact rod pushes the pressure rod to move downwards, thereby pressing the pin sleeve at the lower end of the pressure rod into the positioning pin hole. The lower end of the pressure rod can ensure that the pin sleeve is more evenly stressed, so that the pin sleeve can smoothly and accurately enter the positioning pin hole, and the tooling structure is simple, the operation is also more convenient, and the production efficiency of workers is improved.

Preferably, a bush is provided at the lower end of the through hole, and the lower end of the bush protrudes from the lower end surface of the pressure rod. The lower end of the bush protrudes from the lower end surface of the guide sleeve, so as to prevent the guide sleeve from directly contacting with the mounting surface, thereby being affected by knocking and damaging the mounting surface. The bushing is made of nylon, which has good elasticity, can absorb vibration, and has a good protection effect on the mounting surface.

Preferably, the bush is provided with several grooves, the lower end of the guide sleeve is provided with a threaded through hole communicating with the grooves, and the bush and the guide sleeve are fixedly connected by bolts. The bushing and the guide sleeve are connected by bolts, and the bolts are pushed into the groove of the bushing, so that the bushing and the guide bushing are relatively fixed, the bushing is not easy to fall, and it is also more convenient to install.

Preferably, the upper end of the impact rod is a circular arc surface. In this way, the impact resistance of the upper end of the impact rod is enhanced, the upper end of the impact rod is not easily deformed, and the durability of the tooling is improved.

Preferably, a spring is provided between the impact rod and the guide sleeve. After the pressing rod presses the pin sleeve into the positioning pin hole, the spring is compressed, and the impact rod moves upward under the action of the spring, driving the pressing rod to return to the original position, thereby separating the pressing rod and the pin sleeve.

Preferably, the lower end of the pressing rod is provided with a magnet. When the pin sleeve is sheathed at the lower end of the depression bar, the magnet can absorb the pin sleeve to prevent the pin sleeve from slipping off from the lower end of the depression bar before installation.

Therefore, the utility model has the following beneficial effects: during installation, the pin sleeve is evenly stressed, the installation process is relatively quick, the positioning is accurate, the waste of the pin sleeve is avoided, and the production efficiency of workers is improved.

Among the figure, impact rod 1, guide sleeve 2, pressure rod 3, bushing 4, pin sleeve 5, magnet 6, spring 7.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

In the embodiment shown in FIG. 1 , a pin sleeve tooling includes a guide sleeve 2 , a through hole is provided in the center of the guide sleeve 2 , and an impact rod 1 and a pressure rod 3 are provided in the through hole. A spring 7 is arranged between the impact rod 1 and the guide sleeve 2. The upper end of the impact rod 1 is an arc surface, and the lower end of the impact rod 1 is threadedly connected with the upper end of the pressure rod 3, and the two can slide up and down relative to the through hole. A bushing 4 is provided at the lower end of the through hole, and the bushing 4 is made of nylon. The lower end of the bushing 4 protrudes from the lower end surface of the guide sleeve 2 to ensure smooth contact of the bushing 4 with the mounting surface. The bushing 4 is provided with several grooves, and the lower end of the guide sleeve 2 is provided with a threaded through hole communicating with the grooves. The bushing 4 and the guide sleeve 2 are connected by bolts to ensure that the two are relatively fixed, and the bushing 4 will not be separated from the guide sleeve. 2. The lower end of the depression bar 3 is also provided with a magnet 6 .

During actual use, the pin sleeve 5 is sleeved on the lower end of the depression bar 3 earlier, and the magnet 6 at the lower end of the depression bar 3 can hold the pin sleeve 5 to prevent the pin sleeve 5 from slipping off easily. Then align the pin sleeve 5 with the positioning pin hole on the installation surface, make the bush 4 contact with the installation surface, keep the guide sleeve 2 perpendicular to the installation surface, and then knock the arc surface at the top of the impact rod 1 to press the pin sleeve 5 Insert it into the positioning pin hole to complete the installation and fixing of the pin sleeve 5. Finally, the impact rod 1 drives the pressure rod 3 to return together under the action of the spring 7, so that the next pin sleeve can be installed.
