Description

Technical Field

[0001] This utility model belongs to the field of compressor alloy crankshaft technology, and in particular relates to a precision drilling device for compressor alloy crankshaft. Background Technology

[0002] The compressor alloy crankshaft is the core transmission component of the compressor. It is mostly made of high-strength alloy materials and is installed in the compressor crankcase. Through linkage with the motor rotor, it converts the rotational motion output by the motor into the reciprocating linear motion of the compressor piston. At the same time, it bears gas pressure and mechanical load. It must have high wear resistance, fatigue resistance and impact resistance to ensure the compressor can stably compress refrigerant. It is a key component for maintaining the normal operation of the compressor.

[0003] In the machining of compressor alloy crankshafts, precision holes need to be drilled in parts such as the main journal and connecting rod journal. The accuracy of the hole depth affects the crankshaft performance. Currently, the drilling machines we use lack precise depth control mechanisms due to the crankshaft alloy material, irregular columnar and curved surface structure, which easily leads to uneven drilling depth and some holes exceeding the standard depth. Therefore, it is necessary to design a precision drilling device for compressor alloy crankshafts. The sensor and induction plate precisely control the depth to ensure consistent hole depth, avoid deviations, guarantee the hole position accuracy of the compressor alloy crankshaft, and prevent excessive hole depth from affecting the crankshaft life. The flip-movable tooling fixture allows the crankshaft to be flipped and repositioned without disassembly after fixing, and the other side can be drilled, which greatly reduces secondary positioning errors and improves machining accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a precision drilling device for compressor alloy crankshafts, which features sensors and induction plates to accurately control the depth, ensuring the accuracy of the crankshaft hole position and avoiding excessive hole depth from affecting the crankshaft life. Its flip-movable tooling fixture allows the crankshaft to be flipped and adjusted without disassembly after fixing, thus improving the processing accuracy and solving the aforementioned technical problems.

[0013] In the following description, embodiments of the precision drilling equipment for compressor alloy crankshafts of this utility model will be described with reference to the accompanying drawings.

[0014] Figures 1-5This invention illustrates a precision drilling device for a compressor alloy crankshaft according to an embodiment of the present invention. It includes a base 1, a lifting column module 2 mounted on the rear side of the top of the base 1, a drilling machine 3 slidably connected to the front side of the lifting column module 2, a sensor bracket 5 disposed on the right side of the lifting column module 2, and connecting blocks 4 fixedly connected to both the upper and lower sides of the right side of the lifting column module 2. The two connecting blocks 4 are fixedly connected to the sensor bracket 5. Through the setting of the connecting blocks 4, when the sensor bracket 5 is fixed to one side of the lifting column module 2, the connecting blocks 4 provide support for the sensor bracket 5. The support structure ensures that the sensor bracket 5 does not tilt when installed on one side of the lifting column module 2, improving the stability of the sensor bracket 5. A sensor 6 is installed below the surface of the sensor bracket 5, and a sensing element 7 is installed on the right side of the surface of the drilling machine 3. The sensing element 7 is electrically connected to the sensor 6 via a control box. A sliding groove 8 is fixedly connected to the top of the base 1, and a sliding seat 9 is slidably connected to the top of the sliding groove 8. Two symmetrical fasteners 10 are fixedly installed on the top of the sliding seat 9. The right-side fastener 10 is fixedly connected to the sliding seat 9 by bolts. A pulley 12 is rotatably connected to the lower left side of the sliding seat 9 via a circular block. A pulley 23 is rotatably connected to the left side of the left-side fastener 10. A belt 14 drives the connection between pulley 12 and pulley 23. A protective shell 11 is fixedly connected to the left side of the sliding seat 9. Pulley 12, pulley 12, and belt 14 are all located inside the protective shell 11. The protective shell 11 protects the driving component when installed on the left side of the left-side fastener 10, preventing drilling debris from entering the air and contaminating the drive unit. The interior of wheel 12, pulley 13, and belt 14 improves the service life of the drive components. A cylinder 15 is installed in the inner cavity of the base 1. A linkage rod 16 is fixedly connected to the output end of the cylinder 15. The end of the linkage rod 16 away from the cylinder 15 passes through to the top of the base 1 and is fixedly connected to the inner side of the sliding seat 9. A rectangular groove for sliding the linkage rod 16 is opened on the top of the base 1. A motor 17 is installed in the inner side of the sliding seat 9. The output shaft of the motor 17 is fixedly connected to pulley 13. A connecting pipe is rotatably connected to the inner cavity of the left sliding seat 9 through a rotating shaft.

[0015] Working principle: When using this utility model, first loosen the fixing bolt of the right-side clamp 10 and temporarily move it from the top of the sliding seat 9. Pass one end of the compressor alloy crankshaft through the inner cavity of the connecting pipe of the left-side clamp 10, and then fit the right-side clamp 10 into the other end of the crankshaft. Secure the right-side clamp 10 to the sliding seat 9 with bolts. The cooperation between the two clamps 10 and the connecting pipe achieves a stable clamping of the crankshaft, ensuring that the crankshaft will not shift during processing. After activation, the lifting column module 2 drives the drilling machine 3 to move downward and drill holes in the preset position of the crankshaft. When the drilling machine 3 descends to the set depth, the sensing plate 7 on its right side interacts with the sensor 6 on the sensor bracket 5. The sensor 6 commands the drilling machine 3 to stop through the control box. To prevent downward movement and ensure precise control of hole depth consistency, avoiding depth deviation, after drilling on one side, the motor 17 inside the sliding seat 9 is started. The output shaft of the motor 17 drives the pulley 13 to rotate, which is then driven by the belt 14 to make the pulley 12 rotate synchronously. This drives the crankshaft to flip with the connecting pipe to the other side to be processed. Then, the cylinder 15 inside the base 1 pushes the linkage rod 16, which drives the sliding seat 9 to slide along the slide groove 8 to the preset drilling position. The drilling machine 3 starts again to complete the drilling operation on the other side. Throughout the process, the protective shell 11 protects the pulley 12, pulley 13 and belt 14 to prevent processing debris from affecting the operation of the transmission components. The connecting block 4 ensures that the sensor bracket 5 is installed firmly and ensures accurate transmission of the depth control signal.

[0016] In summary, this precision drilling equipment for compressor alloy crankshafts uses a bolt-on fastener 10 to fix the right-side fastener 10 to the top of the sliding seat 9. One end of the compressor alloy crankshaft passes through the connecting pipe of the left-side fastener 10, and the other end is fitted into the right-side fastener 10 and bolted in place. When the drilling machine 3 is working, it descends to the sensor 6, and the sensing plate 7 sends a signal to stop its movement, ensuring a specific hole depth. Subsequently, the pulley 13 drives the crankshaft to rotate, and the linkage rod 16 pushes the sliding seat 9 to continue drilling on the other side of the crankshaft. This achieves precise depth control by the sensor and sensing plate, ensuring the hole position accuracy of the compressor alloy crankshaft and preventing excessive hole depth from affecting the crankshaft's lifespan. Its flip-movable tooling fixture allows the crankshaft to be flipped and adjusted without disassembly after fixing, thus improving processing accuracy.
