Description

Technical Field

[0001] This utility model relates to the field of cylinder processing technology, specifically a compressor cylinder drilling machine tool. Background Technology

[0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, often referred to as the heart of a refrigeration system. Its core working principle involves drawing in low-temperature, low-pressure refrigerant gas through the suction pipe, compressing the gas using internal mechanisms, and finally discharging high-temperature, high-pressure refrigerant gas through the discharge pipe, thus providing continuous power for the entire refrigeration cycle. Among the key components of a compressor, the cylinder plays a crucial role in containing and compressing the gas. To ensure the stable assembly and reliable operation of the compressor's overall structure, mounting holes for fastening must be precisely machined at specific locations on the cylinder before it is installed onto the compressor body. The precision and efficiency of machining these mounting holes directly affect the compressor's assembly quality, sealing performance, and final operational efficiency.

[0003] Drilling is an indispensable and crucial process in the manufacturing of compressor cylinders. Currently, operators primarily rely on general-purpose or specialized drilling machines to machine mounting holes on the cylinder body. However, a significant technical challenge lies in the fact that compressor cylinder bodies typically require mounting holes to be machined on multiple surfaces in different directions. Under existing methods, operators must first fix the cylinder body on the machine tool, complete drilling on one surface, manually remove the entire cylinder body from the fixture, physically flip it to align the machined surface with the spindle, and then re-clamp and reposition it before drilling the next surface. This cyclical operation of "machining-disassembly-flipping-reassembly-remachining" is not only cumbersome and physically demanding, but each disassembly and reassembly inevitably introduces positioning errors, affecting the relative positional accuracy of the multiple facets. The entire process significantly increases auxiliary work time, resulting in low overall processing efficiency and consuming substantial manpower and time, becoming one of the bottlenecks restricting the production efficiency and machining accuracy of compressor cylinder bodies.

[0004] Based on this, a compressor cylinder drilling machine tool is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-8 As shown, a compressor cylinder drilling machine tool includes a drilling component 12 and a rotating frame 22. Support plates 25 are rotatably mounted at both ends of the rotating frame 22. The support plates 25 are fixedly mounted on the upper end of a base 26. The base 26 is installed inside the bottom of the machine tool body 11. Several clamping components are provided inside the rotating frame 22. A lifting plate 31 is slidably mounted between two support plates 25. A lifting mechanism for moving the lifting plate 31 is provided at the upper end of the base 26. An adjustment mechanism for adjusting the working position of the drilling component 12 is provided inside the upper end of the machine tool body 11. A flipping mechanism for rotating the cylinder is provided inside the machine tool body 11. The lifting mechanism moves the lifting plate 31, supporting the cylinder. The adjustment mechanism adjusts the working position of the drilling component 12, allowing drilling of multiple cylinders. The flipping mechanism facilitates rotating the cylinder, enabling double-sided processing of the cylinder.

[0027] The clamping assembly includes clamping blocks 20. A plurality of clamping assemblies are arranged in an equally spaced array. Each clamping assembly consists of two symmetrically arranged clamping blocks 20. The two clamping blocks 20 are respectively mounted on two mounting rods 21. The mounting rods 21 are slidably mounted on two fixed rods, both of which are fixedly mounted inside the rotating frame 22. One end of each of the two mounting rods 21 is hinged to a first connecting rod 23. The two first connecting rods 23 are respectively hinged to both ends of a hinge rod 24. A sliding rod is fixedly mounted on one side of the hinge rod 24. The sliding rod is slidably mounted in the middle of the rotating shaft at the end of the rotating frame 22. One end of the sliding rod is rotatably mounted on a rotating shaft. The rotary joint 29 is fixed to the output end of the second electric cylinder 30, which is fixed inside the machine tool body 11. The second electric cylinder 30 is electrically connected to the control component 36, which is fixed to the machine tool body 11. In use, when it is necessary to clamp and fix the cylinder, the lifting plate 31 is raised to a fixed height, and the two clamping blocks 20 are in the middle of the cylinder. Then, the output end of the second electric cylinder 30 drives the hinge rod 24 to move. The hinge rod 24 drives the mounting rod 21 to slide through the first connecting rod 23. The mounting rod 21 drives several clamping blocks 20 to move, so that the clamping blocks 20 clamp and fix the cylinder.

[0028] The lifting mechanism includes a lifting plate 31. Several second connecting rods 32 are hinged to the bottom end of the lifting plate 31. These second connecting rods 32 are arranged in pairs, with each pair of second connecting rods 32 on the same side hinged to a third sliding plate 33. The two second connecting rods 32 are symmetrically arranged. Each second connecting rod 32 is mounted on a bidirectional screw 34. Rotating plates are rotatably mounted at both ends of the bidirectional screw 34, and these rotating plates are fixedly mounted on the upper end of the base 26. One end of the bidirectional screw 34 is fixedly connected to the output end of a fourth motor 35, which is also fixedly mounted on the upper end of the base 26. When the working height of the lifting plate 31 needs to be adjusted, the control component 36 controls the fourth motor 35 to start. The output end of the fourth motor 35 drives the bidirectional screw 34 to rotate. The third sliding plate 33 and the bidirectional screw 34 are threaded together, causing the two third sliding plates 33 to move simultaneously in opposite directions. Each third sliding plate 33 moves the lifting plate 31 via the two second connecting rods 32.

[0029] A baffle plate is fixed between the two rotating plates. The baffle plate is located between the two second connecting rods 32, which facilitates the protection of the bidirectional screw 34 during use.

[0030] The adjusting mechanism includes a first sliding plate 13 and a second sliding plate 16. The first sliding plate 13 is fixedly mounted on the upper end of the drilling component 12. The first sliding plate 13 is slidably disposed inside the first fixed box. A first threaded rod 14 is fitted into a threaded hole in the middle of the first sliding plate 13. The first threaded rod 14 is rotatably disposed inside the first fixed box. One end of the first threaded rod 14 is fixedly connected to the output end of a first motor 15. The first motor 15 is fixedly disposed at one end of the first fixed box. The second sliding plate 16 is fixedly mounted on the upper end of the first fixed box. A second threaded rod 17 is fitted into a threaded hole in the middle of the second sliding plate 16. The second threaded rod 17 is rotatably disposed inside the second fixed box. One end of the second threaded rod 17 is fixedly connected to the output end of a second motor 18. The machine tool 18 is fixedly mounted at one end of the second fixed box. Guide slide rods are symmetrically slidably mounted on the second sliding plate 16. The guide slide rods are all fixedly mounted inside the second fixed box. The second fixed box is fixedly connected to the output ends of two first electric cylinders 19. The first electric cylinders 19 are fixedly mounted on the upper end of the machine tool body 11. When it is necessary to adjust the lateral working position of the drilling component 12 during use, the second motor 18 drives the second threaded rod 17 to rotate, so that the drilling component 12 moves along the axis of the second threaded rod 17 under the action of the thread. Similarly, the drilling component 12 moves along the axis of the first threaded rod 14, so that the longitudinal working position of the drilling component 12 can be adjusted. When drilling is required, the output end of the first electric cylinder 19 drives the second fixed box to move, so that the drilling component 12 descends.

[0031] The flipping mechanism includes an external spline shaft fixedly mounted on the rotating shaft at the other end of the rotating frame 22, an internal spline shaft sleeved on the external spline shaft, a fixing block fixedly mounted on the external spline shaft, a threaded hole in the middle of the fixing block, and the fixing block fixedly connected to one end of the connecting pipe 27 by screws. The connecting pipe 27 is slidably mounted at the output end of the third motor 28, and the third motor 28 is fixedly mounted inside the machine tool body 11. In use, when it is necessary to flip the cylinder, the lifting plate 31 descends, and then the output end of the third motor 28 drives the rotating frame 22 to rotate 180 degrees through the connecting pipe 27, thereby flipping the cylinder.

[0032] The above embodiment discloses a compressor cylinder drilling machine tool. When the cylinder needs to be clamped and fixed, the control component 36 controls the fourth motor 35 to start. The output end of the fourth motor 35 drives the bidirectional screw 34 to rotate. The third sliding plate 33 and the bidirectional screw 34 are threaded together, so that the two third sliding plates 33 move simultaneously and in opposite directions. The third sliding plates 33 drive the lifting plate 31 to move through the two second connecting rods 32, so that the lifting plate 31 rises to a fixed height. The two clamping blocks 20 are located in the middle of the cylinder. Then, the output end of the second electric cylinder 30 drives the hinge rod 24 to move. The hinge rod 24 drives the mounting rod 21 to slide through the first connecting rod 23. The mounting rod 21 drives several clamping blocks 20 to move, so that the clamping blocks 20 clamp and fix the cylinder.

[0033] When the lateral working position of the drilling component 12 needs to be adjusted, the second motor 18 drives the second threaded rod 17 to rotate, so that the drilling component 12 moves along the axis of the second threaded rod 17 under the action of the thread. Similarly, the drilling component 12 moves along the axis of the first threaded rod 14, so that the longitudinal working position of the drilling component 12 can be adjusted. When drilling is required, the output end of the first electric cylinder 19 drives the second fixed box to move, so that the drilling component 12 is lowered. When the cylinder needs to be flipped, the lifting plate 31 is lowered, and then the output end of the third motor 28 drives the rotating frame 22 to rotate 180 degrees through the connecting pipe 27, thereby flipping the cylinder.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
