Description

Technical Field

[0001] This utility model relates to the field of piston machining, and in particular to a drilling and cutting device for piston machining. Background Technology

[0002] The piston is a key component of an engine. Through its reciprocating motion within the cylinder, it converts the energy of fuel into mechanical energy, driving the machine. Pistons are typically made of high-temperature, high-pressure resistant materials such as cast iron, forged steel, or aluminum alloys, and come in various shapes to suit the needs of different engines.

[0003] Currently, when manufacturing pistons, drilling and cutting operations are often required. Since most pistons are cylindrical, both ends are usually fixed before drilling and cutting the outer wall using a cutting tool.

[0004] Although the current fixing method can effectively ensure that drilling and cutting operations on the outer surface of the piston are not affected while fixing the piston, in actual use, since only the left and right ends of the piston are fixed, the middle part is often subjected to the cutting force generated by the cutter during the machining process. Since the piston is in a suspended state without support directly below the cutting position, even if the two ends are fixed, the piston is still prone to falling off or deforming downwards under the force. Therefore, a drilling and cutting device for piston machining is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a drilling and cutting device for piston processing, which aims to improve the problem of the lack of support at the bottom of the piston when performing drilling and cutting operations in the prior art.

[0009] As a further description of the above technical solution:

[0010] The inner wall of the inclined plate penetrates the outer wall of the connecting rod, and a drawer slides on the inner wall of the mounting frame.

[0011] As a further description of the above technical solution:

[0012] A fixed column is fixedly connected to the inner wall of the mounting frame located below the inclined plate. A rotating tube is rotatably connected to the outer wall of the fixed column. A push rod is fixedly connected to the outer wall of the rotating tube. The outer wall of the fixed column and the inner wall of the rotating tube are elastically connected by a torsion spring.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up the mounting frame, control plate, spring, connecting rod, support column, rack and tooth groove, it is ensured that after the piston is fixed, the height of the support column can be determined by the combined action of the spring and the outer wall of the piston, and then fixed after determination.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 6 This utility model provides an embodiment of a drilling and cutting device for piston processing, comprising a body 1, which is a drilling and cutting machine for piston processing. The body 1 contains a clamp for fixing the piston and a cutting tool for processing the piston. A support mechanism 2 is provided inside the body 1. The support mechanism 2 includes a mounting frame 21, which is shaped like two connected cuboids. An opening is provided at the top of the upper cuboid. The upper and lower cuboids have the same width and their rear surfaces are on the same plane, but the front end of the upper cuboid is positioned in front of the lower cuboid. The outer wall of the mounting frame 21 is fixedly connected to the inner wall of the body 1. Next, the inner wall of the mounting frame 21 is provided with a sliding groove 22. The number of sliding grooves 22 is set to multiple, and the multiple sliding grooves 22 are arranged in a linear array in the front-back direction. A control plate 23 is slidably connected to the inner wall of the sliding groove 22. The bottom end of the control plate 23 is elastically connected to the inner wall of the sliding groove 22 by a spring 24. One end of the spring 24 is fixedly connected to the bottom end of the control plate 23, and the other end of the spring 24 is fixedly connected to the inner wall of the sliding groove 22. A connecting rod 25 is fixedly connected to the top end of the control plate 23. The connecting rod 25 is cylindrical in shape, and the outer wall of the connecting rod 25 is smooth. A support column 26 is fixedly connected to the top end of the connecting rod 25. The support column 26 is cylindrical in shape.

[0034] Reference Figure 3 , Figure 5 and Figure 6The mounting frame 21 has a positioning component 27 inside, which includes a moving groove 271. The length of the moving groove 271 is longer than the length of the slide groove 22. The left and right sides of the moving groove 271 have areas communicating with the slide groove 22. The moving groove 271 is located on the inner wall of the mounting frame 21 below the slide groove 22. A motor 272 is fixedly connected to the inner wall of the moving groove 271. The output shaft of the motor 272 is fixedly connected to a bidirectional threaded rod 273. The outer side of the bidirectional threaded rod 273 has two threaded sections. The domain is symmetrically arranged with its middle surface in the left and right directions as the symmetrical plane. The end of the bidirectional threaded rod 273 away from the motor 272 is rotatably connected to the inner wall of the moving groove 271. The outer wall of the bidirectional threaded rod 273 is threaded through and connected to the slider 274. The top of the slider 274 is fixedly connected to the rack 275. The number of racks 275 is twice the number of grooves 22. The teeth of the racks 275 are set as sharp teeth. The left and right ends of the control plate 23 are provided with toothed grooves 276. The shape of the toothed grooves 276 matches the shape of the teeth of the racks 275.

[0035] Reference Figure 2 - Figure 4 The mounting frame 21 contains a cleaning component 28, which includes an inclined plate 281. The front end of the inclined plate 281 is lower than its rear end, and the movable distance of the inclined plate 281 is less than its thickness. By comparing the thickness and the movable distance, it is ensured that impurities will not fall through the gap at the front end of the inclined plate 281 as it moves upward. The inner wall of the inclined plate 281 penetrates the outer wall of the connecting rod 25. A fixing post 282 is fixedly connected to the inner wall of the mounting frame 21 below the inclined plate 281. The fixing post 282 is cylindrical, and a rotating tube 283 is rotatably connected to the outer wall of the fixing post 282. The rotating tube 283 is cylindrical and concentrically arranged with the fixing post 282. A cylindrical opening is formed in the middle of the rotating tube 283. The groove ensures that other items can be installed between the rotating tube 283 and the fixed post 282. A push rod 284 is fixedly connected to the outer wall of the rotating tube 283. The outer wall of the fixed post 282 and the inner wall of the rotating tube 283 are elastically connected by a torsion spring 287. One end of the torsion spring 287 is fixedly connected to the outer wall of the fixed post 282, and the other end of the torsion spring 287 is fixedly connected to the inner wall of the rotating tube 283. The torsion spring 287 is located in the groove in the middle of the rotating tube 283. A pull rope 285 is fixedly connected to the outer wall of the rotating tube 283. The pull rope 285 is inelastic. The outer wall of the pull rope 285 penetrates the inner wall of the mounting frame 21. The front end of the pull rope 285 is located at the front side of the mounting frame 21. A drawer 286 slides on the inner wall of the mounting frame 21. The drawer 286 can be removed from the inside of the mounting frame 21.

[0036] Working principle: When in use, the operator first drives the bidirectional threaded rod 273 to rotate through the motor 272, so that the slider 274 moves away from the control board 23 under the drive of the bidirectional threaded rod 273.

[0037] After the movement is complete, the staff manually presses down on the support column 26, causing the support column 26 to move downward, ensuring that the space used to clamp the piston is released, and ensuring that the piston installation process is smooth.

[0038] During the downward pressing of the support column 26, the operator starts the motor 272 and causes it to drive the bidirectional threaded rod 273 to rotate in the opposite direction, thereby causing the slider 274 to drive the rack 275 to move towards the tooth groove 276.

[0039] When the teeth of the rack 275 are precisely engaged in the gap of the tooth groove 276, the height of the connecting rod 25 and the support column 26 is fixed because the control plate 23 cannot move up or down.

[0040] At this time, the worker installs the piston that needs to be drilled into the fixture, and then starts the motor 272 again. When the motor 272 drives the bidirectional threaded rod 273 to rotate, the limit of the control plate 23 is released, and under the action of the spring force of the spring 24, there is an upward force.

[0041] Since the piston is in the installed state at this time, when the support column 26 moves upward with the connecting rod 25 and the control plate 23, it can just move to the position that contacts the lower surface of the piston. Therefore, when the motor 272 is started again to fix the vertical height of the support column 26, it can just play the role of supporting the piston.

[0042] After the cutting was completed, the workers released the limit on the support column 26, removed the piston, and then pulled the rope 285.

[0043] When the rope 285 is pulled, its rear end moves forward, thus pulling the rotating tube 283 to rotate, which in turn causes the push rod 284 to rotate under the drive of the rotating tube 283, thereby pushing the inclined plate 281 during the rotation process.

[0044] Afterwards, the staff released the pull rope 285. At this time, the rotating tube 283 was reset under the action of the torsion spring 287, and the push rod 284 was also reset, so that the push rod 284 did not contact the bottom end of the inclined plate 281. At this time, the inclined plate 281 moved downward under the action of gravity.

[0045] By repeating the above operation, the tilting plate 281 can be moved up and down continuously, thereby generating vibration. Since the tilting plate 281 is tilted, during the vibration process, the debris enters the drawer 286 through the inclined surface of the tilting plate 281, thereby completing the collection of debris and facilitating cleaning by the staff.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
