Description

A fastening tool for oil port cover

technical field

The utility model relates to a tool, in particular to a fastening tool for an oil port cover that ensures that the oil port cover is installed in place and meets the tightening torque requirements.

Background technique

The oil port cover of a car engine is in the shape of an irregular petal. Due to the lack of suitable tools, it is generally installed and tightened directly by hand. The assembly is time-consuming and laborious and cannot meet the required tightening torque. When the tightening torque is too large, the oil port cover is easily damaged. , If the tightening torque is too small, the seal will not be tight, so that the assembly quality of the engine will be poor, and the safety of the car will be difficult to guarantee.

Utility model content

The utility model mainly solves the technical problem that the manual tightening of the oil port cover is time-consuming and laborious and cannot meet the tightening torque requirement; it provides a fastening tool for the oil port cover that ensures that the oil port cover is installed in place and meets the tightening torque requirement.

In order to solve the above-mentioned technical problems, the utility model mainly adopts the following technical solutions:

An oil port cover fastening tool of the utility model is used for tightening and installing the oil port cover of an automobile engine, and comprises a sleeve. The surface of the other end is provided with a connecting piece matched with the fixed button force wrench. The groove of the sleeve coincident with the oil port cover covers and clamps the oil hole cover. The corresponding fixed button force wrench is inserted into the connecting piece and drives the sleeve to rotate. Then tighten or loosen the oil port cover, the tightening torque can meet the specified installation process requirements and the tightening process is constant, eliminating the disadvantages of manual operation intensity and assembly quality can not be guaranteed, so that the safety of the engine is effectively improved, fixed button force wrench Optional manual or pneumatic.

Preferably, the connecting piece is a cylinder or a square cylinder or an outer hexagonal cylinder, the bottom of the connecting piece is set at the center of the surface of the sleeve and fixed to the surface of the sleeve, and the top of the connecting piece is provided with a concave The hole, the concave hole coincides with the head of the fixed button force wrench, and the fixed button force wrench is inserted into the concave hole of the connector to pull the sleeve to rotate.

Preferably, the connecting piece is in the shape of a cylinder with reduced diameter, the diameter of the upper section of the connecting piece is larger than the diameter of the lower section of the connecting piece, and the thinner lower section structure can reduce weight and save materials.

Preferably, the bottom of the connector is welded to the surface of the sleeve, and the tooling is easy to manufacture and low in cost.

As a preference, the bottom of the connector is provided with a foot integrated with the connector, the foot is provided with a through hole, the surface of the sleeve is provided with a mounting screw hole matching the through hole, and the connection The parts are threadedly connected with the sleeve by fixing bolts, and the sleeve and connecting parts of the split structure design can reduce the overall height of the tooling, improve portability and storage, and have a wide range of applications.

Preferably, the surface of the sleeve is provided with a number of uniformly distributed process holes, which can reduce the weight of the sleeve, save materials and costs, and correspondingly reduce the work intensity of assembly.

The beneficial effects of the utility model are as follows: cover and clamp the oil port cover with a sleeve matching the oil port cover, insert the corresponding fixed button force wrench into the connecting piece and pull it to drive the sleeve to rotate, and then tighten or loosen it For the oil port cover, the tightening torque can meet the specified installation process requirements and the tightening process is constant, which eliminates the disadvantages of heavy manual operation and unguaranteed assembly quality, and effectively improves the safety of the engine.

Detailed ways

The technical solutions of the present utility model will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

Embodiment 1: A kind of oil port cap fastening tool of this embodiment 1 is used for tightening and installing the oil port cap of an automobile engine, as shown in FIG. The shape of the cover coincides, and a connecting piece 2 is welded at the center of the surface of the other end of the sleeve. The connecting piece is in the shape of a variable-diameter cylinder. The hole matches the head of the pneumatic torque wrench.

When in use, cover the sleeve directly and block the oil port cap, insert the head of the pneumatic fixed button force wrench into the top concave hole of the connecting piece and rotate, the connecting piece drives the sleeve under the pull of the fixed button force wrench Rotate, correspondingly the oil port cover is also tightened with a constant button force and reaches the tightness required by the process.

Embodiment 2: An engine oil port cover fastening tool in this embodiment 2, as shown in Figure 2, includes a sleeve, and a connecting piece is designed at the center of the surface of the other end of the sleeve, and the bottom of the connecting piece is designed with a connecting piece. The foot 22 of the integral structure is designed with a through hole 23 on the foot, and a mounting screw hole matched with the through hole is opened on the surface of the sleeve. A number of uniformly distributed process holes 12 are also designed on the surface of the sleeve, and the process holes are used to reduce the weight of fastening tooling. The other parts of this embodiment 2 are similar to the corresponding parts of embodiment 1, and will not be repeated here.

The above descriptions do not limit the utility model, and the utility model is not limited to the examples described above, any changes, modifications, additions or replacements made by those skilled in the art within the essential scope of the utility model are all It should be regarded as the protection scope of the present utility model.
