Description

Technical Field

[0001] This utility model relates to the field of production and processing, and in particular to a processing device for piston oil holes. Background Technology

[0002] Piston oil holes are a key structure in the internal design of engine pistons, mainly used to achieve lubrication and cooling functions, ensuring reliable operation of the piston under high temperature and high pressure environments.

[0003] To ensure proper lubrication of the piston, multiple oil holes are often made on the same piston to ensure that the lubricating oil can make good contact with different positions of the piston during use. Therefore, during the production process, after the same piston has been drilled once, its position is adjusted and then drilled again.

[0004] Currently, in order to create multiple holes, workers often need to remove the piston from the fixing assembly after the piston has been drilled once, adjust it to the appropriate position, fix it again, and then perform the drilling operation. Although the drilling operation can be completed through the above steps, it takes a lot of time to fix and disassemble the piston, which is quite troublesome. Therefore, a processing device for piston oil holes is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a processing device for piston oil holes, which aims to improve the problem in the prior art that it is inconvenient to adjust the position of the piston and then drill again after the piston has completed a drilling operation.

[0010] The starting component includes an installation compartment, which is located on the inner wall of the machine body. A cylinder is fixedly connected to the inner wall of the installation compartment. The output shaft of the cylinder passes through the inner wall of the machine body at the lower end of the installation compartment and is fixedly connected to an installation plate. A motor is fixedly connected to the lower end of the installation plate, and a drill rod is fixedly connected to the output shaft of the motor.

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

[0012] The steering groove is spiral in shape, and there are multiple steering grooves. The total number of spiral turns of the multiple steering grooves is one turn, and the number of spiral turns of each steering groove is the same.

[0019] As a further description of the above technical solution:

[0020] The control ring is circular in shape, and the inner diameter of the push block matches the outer diameter of the rotating column.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 3 This utility model provides an embodiment of a processing device for piston oil holes, including a machine body 1, which is a drilling machine for processing piston oil holes. The machine body 1 is equipped with a starting component 2, which includes a mounting chamber 21. The mounting chamber 21 is opened on the inner wall of the machine body 1. A cylinder 22 is fixedly connected to the inner wall of the mounting chamber 21. The output shaft of the cylinder 22 can be moved up and down by a starting control valve. The output shaft of the cylinder 22 passes through the inner wall of the lower end of the mounting chamber 21 of the machine body 1 and is fixedly connected to a mounting plate 23. The mounting plate 23 is cuboid in shape. A motor 24 is fixedly connected to the lower end of the mounting plate 23. A drill rod 25 is fixedly connected to the output shaft of the motor 24. A spiral groove is opened on the outer wall of the drill rod 25. The groove ensures that the waste generated after drilling can be discharged through the groove.

[0034] Reference Figure 2 - Figure 4 The inner wall of the machine body 1 is rotatably connected to a rotating rod 3. The rotating rod 3 is cylindrical in shape, and there are two rotating rods 3. The two rotating rods 3 are fixedly connected to a clamp 4 at one end that is close to each other. The clamp 4 can clamp the left and right ends of the piston to be processed, thereby ensuring that the piston cannot move during the drilling process.

[0035] Reference Figure 3 - Figure 5 The left end of the left rotating rod 3 and the interior of the body 1 are jointly provided with a rotating mechanism 5. The rotating mechanism 5 includes a pneumatic pipe 51. The inner wall of the pneumatic pipe 51 is connected to a piston-connected starting block 52. The top end of the starting block 52 is elastically connected to the inner wall of the pneumatic pipe 51 by a spring 53. One end of the spring 53 is fixedly connected to the top end of the starting block 52, and the other end of the spring 53 is fixedly connected to the inner wall of the pneumatic pipe 51. The inner wall of the pneumatic pipe 51 is connected to a piston-connected pushing block 54. The width of the starting block 52 is wider than the width of the pushing block 54. By setting the width comparison, it is ensured that even if the starting block 52 moves a small distance, the pushing block 54 can move a long distance. The right end of the pushing block 54 is fixedly connected to a control ring 55.

[0036] Reference Figure 6The control ring 55 is provided with a locking component 56. The locking component 56 includes a sliding groove 561, which is formed on the inner wall of the control ring 55. A sliding plate 562 is slidably connected to the inner wall of the sliding groove 561. The sliding plate 562 can only slide along the inner wall of the sliding groove 561 and cannot rotate. A control rod 563 is fixedly connected to one end of the sliding plate 562 near the middle of the control ring 55. The other end of the sliding plate 562 away from the control rod 563 is elastically connected to the inner wall of the sliding groove 561 by a spring 564.

[0037] Reference Figure 3 - Figure 5 The rotating mechanism 5 also includes a rotating column 57. The control ring 55 is circular in shape, and the inner diameter of the push block 54 matches the outer diameter of the rotating column 57. The right end of the rotating column 57 is fixedly connected to the left end of the left rotating rod 3. The outer wall of the rotating column 57 has a turning groove 58, which is spiral in shape. There are multiple turning grooves 58, and the total number of spiral turns of the multiple turning grooves 58 is one turn. The number of spiral turns of each turning groove 58 is the same. This setting ensures that the angle of rotation of the rotating column 57 is consistent each time. The left end of the turning groove 58 is deeper than the right end. The outer wall of the rotating column 57 has a reset groove 59, which is horizontal in shape. The right end of the reset groove 59 is deeper than the left end. The length of the control rod 563 is longer than... The deepest point of the steering groove 58 and the length of the control rod 563 are greater than the deepest point of the reset groove 59. By setting the depth, it is ensured that when the control ring 55 moves from left to right, the control rod 563 moves from inside the steering groove 58, and when the control ring 55 moves from right to left, the control rod 563 moves from inside the reset groove 59. The left and right ends of the reset groove 59 are connected to the left and right ends of each pair of adjacent steering grooves 58, respectively. The right side of the reset groove 59 is deeper than the right side of the steering groove 58, and the left side of the steering groove 58 is deeper than the left side of the reset groove 59. The final shape formed by connecting all the steering grooves 58 and all the reset grooves 59 is interconnected. By setting the shape to be interconnected, it is ensured that the control rod 563 is always in the groove formed by connecting the steering groove 58 and the reset groove 59.

[0038] Working principle: When in use, the operator fixes the piston that needs to be opened for oil holes inside the machine body 1 using the clamp 4. Then, the cylinder 22 and the motor 24 are started, so that the mounting plate 23 drives the motor 24 and the drill rod 25 to move downward together. During the downward movement, the drill rod 25 rotates under the drive of the motor 24, thereby ensuring that when the drill rod 25 moves to the position of contact with the piston, it can drill smoothly.

[0039] After a drilling operation is completed, the worker uses cylinder 22 to move the mounting plate 23 upward.

[0040] When the mounting plate 23 moves upward to contact the bottom end of the starting block 52, the mounting plate 23 continues to move upward, which can drive the starting block 52 to move upward synchronously. This causes the starting block 52 to occupy the internal space of the air pressure pipe 51, thereby reducing the internal space of the air pressure pipe 51 and increasing the internal air pressure. When the internal air pressure of the air pressure pipe 51 increases, the push block 54 moves to the right under the push of the air pressure, and pushes the control ring 55 to move to the right.

[0041] When the control ring 55 moves to the right, the control ring 55 drives the control lever 563 to move to the right.

[0042] Since the right end of the steering groove 58 is deeper than the left end, when the control lever 563 is on the left side, at the junction of the steering groove 58 and the reset groove 59, it can exist in the groove deeper than the other end under the elastic force of the spring 564. Therefore, when the control lever 563 moves from left to right, it can only move along the trajectory of the steering groove 58, thereby pushing the inner wall of the steering groove 58 to make the rotating column 57 rotate, thereby driving the rotating rod 3 and the clamp 4 to rotate, thus making the piston rotate.

[0043] When the mounting plate 23 moves downward again with the cylinder 22, the starting block 52 is able to move downward during the downward movement of the mounting plate 23 due to the elastic force of the spring 53, until it stops after reaching the lowest point.

[0044] As the starting block 52 moves downward, the internal space of the air pressure pipe 51 increases, so the air pressure inside the air pressure pipe 51 decreases. Therefore, the pushing block 54 can be reset under the action of air pressure, and drive the control ring 55 to reset.

[0045] At this time, because the control ring 55 drives the control lever 563 to move from right to left, and when the control lever 563 is at the rightmost end, under the elastic force of the second spring 564, it is in the deeper part of the turning groove 58 and the reset groove 59. Therefore, during the movement from right to left, the control lever 563 can only be reset through the reset groove 59, so the rotating column 57 will not rotate at this time.

[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.
