Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a machining mechanism for a crankshaft hole of a cylinder seat. Background Art

[0002] The compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas and is the heart of the refrigeration system. It draws in low-temperature, low-pressure refrigerant gas from the intake pipe, compresses it through the piston driven by the motor, and then discharges high-temperature, high-pressure refrigerant gas to the exhaust pipe, providing power for refrigeration. It is widely used in energy-saving refrigerators, freezers, air conditioners, or dehumidifiers. The cylinder seat is an important component of the compressor. After the cylinder seat is formed, it needs to be drilled and polished. The drilling requires vertical drilling of the crankshaft mounting part of the cylinder seat.

[0015] The present invention will be described in detail below with reference to the accompanying drawings.

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0017] See Figures 1 to 4The utility model provides a machining mechanism for a crankshaft hole of a cylinder seat, which comprises a base plate 1. A positioning seat 2 and a stabilizing block 3 for the cylinder seat to abut against are provided at the upper end of the base plate 1. A movable groove is provided at the top of the stabilizing block 3. A tilting piece 4 is rotatably and elastically provided in the movable groove. A pressing platform 5 is provided on the lower side of the front end of the tilting piece 4. A cylinder 6 for pressing down the tilting piece 4 is provided downwardly above the stabilizing block 3. A pressing column is provided at the end of the piston rod of the cylinder 6. The cylinder drives the pressing column to press down the tilting piece, so that the tilting piece tilts up to loosen the cylinder seat. A drilling rig 8 is provided above the base plate 1 and is located above the tilting piece 4. Circular holes for the drill bit of the drilling rig 8 to pass through are provided on the tilting piece 4 and the pressing platform 5. The cylinder drives the pressure column to press down the lift piece, causing it to lift up to loosen the cylinder seat. The staff places the cylinder seat on the positioning seat and positions it. The piston seat of the cylinder seat is against the stabilizing block. The crankshaft mounting part of the cylinder seat remains vertical. The cylinder drives the pressure column to rise and reset. The lift piece drives the pressure platform to press down the crankshaft seat of the cylinder seat under the action of elasticity. The circular hole and the crankshaft mounting part of the cylinder seat are on the same axis. The drill bit of the drilling rig drills a hole in the cylinder seat through the circular hole to complete the processing of the crankshaft hole of the cylinder seat.

[0018] The upper end of the positioning base 2 is provided with a central cylindrical portion 2.2 and two horizontal portions 2.1 at the front and rear. A positioning hole is provided in the center of the cylindrical portion 2.2. The crankshaft mounting portion of the cylinder base is positioned in the positioning hole, with the three legs of the cylinder base resting against the horizontal portions and the piston seat of the cylinder base resting against the stabilizing block. The crankshaft mounting portion of the cylinder base remains vertical, thus positioning the cylinder base. The cylinder then presses against the crankshaft seat of the cylinder base to secure the cylinder base.

[0019] See Figure 1 、 Figure 4 The tilting member 4 is composed of a flat plate 4.1 and a protrusion 4.2. The upper side of the rear end of the flat plate 4.1 extends upward to form the protrusion 4.2, and the top of the protrusion is provided with a rounded corner. The protrusion and the flat plate form an L-shape, and the upward-extending protrusion makes it easier to press down to tilt the tilting member.

[0020] The top of the stabilizing block 3 is provided with a frame block, and the cylinder 6 is installed on the frame block. The protrusion 4.2 has notches symmetrically provided on the left and right sides, and an elastic member 7 is connected between the notches and the frame block. After the pressure column of the cylinder is separated from the tilting member, the elastic member drives the tilting member to elastically press down the cylinder seat.

[0021] The material of the pressing platform 5 is plastic. The pressing platform of plastic material can reliably press the crankshaft seat of the cylinder block, and plastic can avoid damaging the cylinder block.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention.
