Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention relates to an air compressor having an improved mounting seat, and in particular Motors with different capacities can be replaced and mounted on one mounting seat. Therefore, for manufacturers, it has the same capacity as the conventional air compressor. Production and assembly costs, etc. compared to those that can only be fitted with a motor Air compressor with excellent economical and practical effects Concerned.

[0002]

[Prior art]

  Small air compressors are currently used to fill various everyday items with air. It is widely used every day, such as automobile tires, life preservers, inflatable boats for marine accidents, etc. It is used for filling air.   However, the volume of a small air compressor is commonly used as a power source. Determined according to the capacity (output) of the motor There will be some restrictions. The output of current air compressors is Each is set within a certain range, and the motor of a specific output responds accordingly. It is designed to be mounted on the same standard mounting seat. Therefore, different outputs When a force air compressor is needed, the manufacturer It is necessary to design and manufacture a mounting seat of another standard according to the cost and materials for that. It was uneconomical because it required a fee.

[0003]   Here, regarding the structure of a conventionally known air compressor, first, referring to FIG. While explaining. This air compressor uses a mounting seat fixing screw 82 to The mounting seat 80 is connected and fixed to the binder 81. To be described later Thus, the cylinder 81 and the mounting seat 80 may be integrally formed.

[0004]   Conventional small air compressors come in two different operating modes. One of them has a structure as shown in FIGS. 14, 15 and 16. It That is, the first mounting hole 83 and the second mounting hole 84 are formed in the mounting seat 80, A pair of motor fixing screw holes 85 are formed at opposite positions on both sides of the first mounting hole 83. Has been. The output shaft 861 of the motor 86 is inserted into the first mounting hole 83, The connector 86 itself is attached by a mounting screw 87 that is screwed into the motor fixing screw hole 85. Is fixed. The ball bearing 8 is provided in the second mounting hole 84. 8 (or a plain bearing (not shown)) is attached.

[0005]   In this case, the power from the motor 86 is the drive gear 862 at the tip of the output shaft 861. Is transmitted from the driven wheel 89 mounted on the flywheel 890 to the flywheel. Is transmitted to the piston rod 892 via an eccentric pin 891 provided on the As a result, the piston in the cylinder 81 reciprocates and compressed air is obtained. It has become.   In this type of air compressor, the screw hole 85 for fixing the motor is used. The power of the small capacity (small output) motor 86 attached to the first attachment hole 83 Via a power transmission mechanism including an intermediate gear such as a drive gear 862 and a driven gear 89 It is transmitted to the piston.

[0006]   Another type of conventionally known small air compressor is shown in FIG. 18 and a structure as shown in FIG. That is, the mounting seat 90 Is attached to the cylinder 91 with a mounting seat fixing screw 92. Mounting seat 90 Has a single mounting hole 93 formed in the lower half thereof. A pair of screw holes 94 for fixing the motor are opened at the facing positions. Motor 95 Output shaft 951 is inserted into the mounting hole 93, and the motor 95 itself is fixed to the motor. It is fixed by a mounting screw 96 screwed into the screw hole 94 for It

[0007]   In this case, the power of the large-capacity motor 95 is supplied to the output shaft 951. Eccentric pin 971 directly transmitted to the lie wheel 97 and provided on the flywheel 97 Is transmitted to the piston rod 98 via the The compressed air is obtained by the reciprocating movement of the engine.

[0008]   In the conventionally known air compressors with these two types of different operation systems, For two different types of mounting seats, that is, small capacity motor 86 Mounting seat 80 and other mounting seats for large capacity motors 95. A 90-like configuration is needed and the third of the intermediate capacity of these motors is required. When using a type 3 motor, design and manufacture a type 3 mounting seat for that purpose. Need to That is, if the capacity of the motor is different, the outer diameter of the motor Also changes, and therefore the pair of motor fixing screw holes that are opened on both sides of the mounting hole. This is because the interval also increases or decreases.   Therefore, in the conventional air compressor, each time the output changes, Since it is necessary to manufacture mounting seats of different standards, development and manufacturing costs are high. However, there is a problem that it is difficult to reduce the cost.

[0009]

[Problems to be solved by the device]

  The inventor solves the above problems based on his many years of practical experience and constant research. Therefore, the present invention was completed.   That is, the present invention replaces motors with different capacities with a single mounting seat as needed. Can be attached, thus keeping production and assembly costs low It is intended to provide an air compressor.

[0010]

[Means for Solving the Problems]

  The purpose of the above is   The piston is parallel to the cylinder of the air compressor and more than the side of the cylinder. It is a flat plate-like member that is provided so as to project to the rod side, and A power transmission mechanism that converts motion to reciprocating motion and transmits it to the piston rod is installed. In an air compressor with a mounting seat for   A first mounting hole made of a simple cylindrical surface is provided near the cylinder of the mounting seat, At the position separated from the cylinder, inward at the opening end on the cylinder side. A second mounting hole having an overhanging annular flange bottom is provided, and the first and second mounting holes are provided. Provide at least one pair of motor fixing screw holes near the mounting holes,   When using a small capacity motor, mount the motor coaxially with the first mounting hole. The drive gear attached to the mounting seat and the second attachment hole to the output shaft of the motor. Driven gear meshing with, flywheel, eccentric pin connected to piston rod, and Set the center axis of the power transmission mechanism consisting of the center axis to the ball bearing or plain bearing. So that it can be attached rotatably   When using a large capacity motor, mount the motor coaxially with the second mounting hole. Attach the eccentric pin that is attached to the mounting seat and directly connected to the output shaft to the piston rod. I have attached a flywheel that I have,   The above-mentioned mounting seat that can be used for both small capacity and large capacity motors Can be achieved by an air compressor having

[0011]   In that case, each of the first mounting hole and the second mounting hole of the mounting seat has two sets of motors. It is also possible to have a fixing screw hole.   Cylinder and mounting seat are made individually, and both are connected and fixed to each other. Alternatively, it is also possible to integrally form the cylinder and the mounting seat.   If necessary, the opening on the cylinder side in which the flange bottom of the second mounting hole is formed. At the opening end opposite to the end, a ring-shaped ridge protruding outwards is formed. It is also recommended to do.
