Description

Technical Field

[0001] This utility model relates to the technical field of reaming and burnishing machines, specifically to an integrated reaming and burnishing machine. Background Technology

[0002] The reaming and burnishing integrated machine is a composite processing equipment that can complete the two processes of reaming and burnishing at the same time. Reaming is the process of finishing a drilled, cast, or forged hole with a reamer, usually as the last process of hole processing. Burnishing is the process of applying pressure to the surface of the workpiece with a high-hardness rolling tool to cause plastic deformation, thereby improving surface roughness, increasing dimensional accuracy, and enhancing surface hardness.

[0003] Some existing reaming and burnishing integrated machines generally use a threaded shaft to drive the base plate to move the fixture to adjust the position of the workpiece, thereby completing the reaming and burnishing processes in sequence. However, after the device has been used for a long time, due to thread wear, base plate wear, or other reasons such as reaming and burnishing, a strong lateral force is applied to the side wall of the workpiece hole, which may cause the fixture position to deviate after adjustment, thereby reducing the processing accuracy of the reaming and burnishing integrated machine. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to provide a reaming and burnishing integrated machine that can effectively avoid positional deviations in the base plate after adjustment and improve the processing accuracy of the reaming and burnishing integrated machine.

[0005] To solve the above problems, this utility model provides an integrated boring and polishing machine, comprising: a slide rail with several conical grooves on its inner wall, a base plate slidably mounted in the slide rail, a piston groove on the base plate corresponding to the position of the conical groove, a piston rod slidably mounted in the piston groove, and the end of the piston rod near the conical groove being frustoconical; a water storage tank is provided in the base plate and is located between the several piston grooves; the interior of the water storage tank is connected to the interior of the corresponding piston groove through an electrically controlled valve and a connecting pipe; and a piston plate is slidably mounted in the water storage tank. The drive mechanism, which is located on the base plate, is used to drive the base plate to slide back and forth within the slide rail.

[0006] Preferably, the driving mechanism includes a threaded rod that passes through a piston plate, with one end of the threaded rod rotatably connected to one end of a slide rail. The other end of the slide rail is provided with a driver, and the driving end of the driver is fixedly connected to the other end of the threaded rod through a connecting mechanism.

[0007] Preferably, a round tube is threaded onto the outer periphery of the threaded rod, and the round tube is fixedly inserted through the piston plate and slidably connected to the base plate.

[0008] Preferably, the connecting mechanism includes an air storage tank, which is opened at the other end of the threaded rod. A piston plate is slidably installed in the air storage tank. A threaded tube is slidably installed in the opening of the air storage tank, and one end of the threaded tube is fixedly connected to the piston plate. The other end of the threaded tube is provided with a threaded shaft. One end of the threaded shaft is threaded into the threaded tube, and the other end of the threaded shaft is fixedly connected to the driving end of the driving mechanism and rotatably connected to the slide rail.

[0009] Preferably, the cross-section of the gas storage tank opening is square, the threaded tube is a square tube, and the outer peripheral wall of the threaded tube is in contact with the inner wall of the gas storage tank opening.

[0010] Preferably, a plurality of receiving grooves are symmetrically opened on the inner wall of the opening of the gas storage tank, and a limiting groove is opened on the outer wall of the threaded tube at the position corresponding to the receiving groove. A spring is provided in the receiving groove, and both ends of the spring are fixedly connected to the inner wall of the corresponding receiving groove, and the middle part of the spring is inserted into the corresponding limiting groove.

[0011] This utility model has the following beneficial effects: When using this improved reaming and burnishing integrated machine, after the position of the base plate is adjusted, the position of the base plate can be locked by the extension and retraction of the piston rod, and the position of the base plate is automatically calibrated at the same time. This ensures that the workpiece on the fixture is always located in the reaming mechanism or the burnishing mechanism, avoiding positional deviation of the base plate after adjustment and reducing the processing accuracy of the reaming and burnishing integrated machine.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] See also Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, according to an embodiment of the present invention, a reaming and polishing integrated machine is provided, comprising: a slide rail 1, on which a plurality of conical grooves 5 are provided opposite to each other on its inner wall, a base plate 2 is slidably mounted in the slide rail, a piston groove 6 is provided on the base plate 2 at a position corresponding to the conical grooves 5, a piston rod 7 is slidably mounted in the piston groove 6, and the end of the piston rod 7 near the conical groove 5 is truncated cone-shaped, a water storage tank 8 is provided in the base plate 2, and the water storage tank 8 is located between the plurality of piston grooves 6, the interior of the water storage tank 8 is connected to the interior of the corresponding piston groove 6 through an electrically controlled valve and a connecting pipe, and a piston plate is slidably mounted in the water storage tank 8; The drive mechanism 3 is located on the base plate 2 and is used to drive the base plate 2 to slide back and forth within the slide rail 1.

[0020] In this embodiment, (please refer to...) Figure 1 and Figure 2 As shown, the slide 1 is fixedly mounted on the platform of the reaming and burnishing machine by bolts, and several conical grooves 5 are divided into two groups and respectively located directly below the reaming mechanism and the burnishing mechanism of the reaming and burnishing machine. The base plate 2 has threaded holes for the installation of fixtures. When this improved reaming and burnishing machine is in use, the drive mechanism 3 is started, and the base plate 2 is driven to slide in the slide 1, thereby driving the workpiece to be aligned with the reaming mechanism and the burnishing mechanism in sequence through the fixture, so as to complete the reaming and burnishing of the workpiece. When the drive mechanism 3 drives the base plate 2 to slide forward, the electric control valve opens, first driving the piston plate 9 to slide forward in the water storage tank 8 (piston plate 9 is a square plate) until the piston plate 9 and the inner wall of the water storage tank 8 come into contact with each other. During this process, some hydraulic oil in the piston groove 6 can be drawn into the water storage tank 8 through the electric control valve and connecting pipe, thereby completely drawing the piston rod 7 into the piston groove 6 and pulling the piston rod 7 out of the conical groove 5 to release the positioning constraint state of the base plate 2. At this time, the mutual contact between the piston plate 9 and the inner wall of the water storage tank 8 pushes the base plate 2 to slide forward in the slide rail 1. After the base plate 2 moves directly below the reaming mechanism or the burnishing mechanism, the drive mechanism 3 drives the piston plate 9 to slide in the reverse direction within the water storage tank 8, thereby pressing the hydraulic oil in the water storage tank 8 into the piston groove 6 through the electronically controlled valve and connecting pipe, so as to push the piston rod 7 out of the piston groove 6 and insert the frustum end of the piston rod 7 into the conical groove 5. The constraint and limitation of the base plate 2 are completed by the mutual contact between the frustum end of the piston rod 7 and the inner wall of the conical groove 5. Please refer to Figure 3 As shown, if the position of the base plate 2 deviates during the process of inserting the frustum end of the piston rod 7 into the conical groove 5, the position of the base plate 2 can be automatically adjusted by the mutual contact between the frustum end of the piston rod 7 and the inner wall of the conical groove 5, so that the workpiece is always located in the fixed position of the reaming mechanism or the burnishing mechanism, and the position of the base plate 2 is calibrated. When the base plate 2 moves in reverse to reset, the drive mechanism 3 first drives the piston plate 9 to draw the hydraulic oil in the piston groove 6 back into the water tank 8 to release the locked state of the base plate 2. Then the electric control valve is closed, and the piston plate 9 slides in reverse in the water tank 8. Since the hydraulic oil cannot flow into the piston groove 6, the piston plate 9 moves in reverse to reset the base plate 2 together with the hydraulic oil due to the mutual contact between the hydraulic oil and the piston plate 9 and the inner wall of the water tank 8. Then the replacement of the workpiece on the base plate 2 is completed according to the existing fixture usage method. When using this improved reaming and burnishing integrated machine, after the position adjustment of the base plate 2 is completed, the position of the base plate 2 can be locked by the extension and retraction of the piston rod 7, and the position of the base plate 2 is automatically calibrated at the same time, so that the workpiece on the fixture is always located in the reaming mechanism or the burnishing mechanism, avoiding positional deviation of the base plate 2 after adjustment and reducing the processing accuracy of the reaming and burnishing integrated machine.

[0021] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the drive mechanism 3 includes a threaded rod 31, which passes through the piston plate 9, and one end of the threaded rod 31 is rotatably connected to one end of the slide rail 1. The other end of the slide rail 1 is provided with a driver 32, and the drive end of the driver 32 is fixedly connected to the other end of the threaded rod 31 through the connecting mechanism 4. In this embodiment, please refer to Figure 2 and Figure 4 As shown, when the piston plate 9 slides, the driver 32 drives the threaded rod 31 to rotate in the forward or reverse direction through the connecting mechanism 4. (The driver 32 is mainly composed of a housing, a servo motor, a gear transmission structure, and a drive shaft.) Due to the mutual contact between the piston plate 9 and the inner wall of the water tank 8 and the mutual contact between the bottom plate 2 and the inner wall of the slide groove 1, the rotating threaded rod 31 drives the piston plate 9 to move in the forward or reverse direction.

[0022] In a further preferred embodiment of this utility model, such as Figure 4 As shown, a round tube 33 is threaded on the outer periphery of the threaded rod 31, and the round tube 33 is fixedly inserted through the piston plate 9 and slidably connected to the bottom plate 2. In this embodiment, please refer to Figure 4As shown, (a circular hole is provided on the base plate 2 for the installation of the circular tube 33, and a sealing ring is installed on the inner wall of the circular hole to seal the gap between the circular rod and the base plate 2). The piston plate 9 is threadedly connected to the threaded rod 31 through the circular tube 33, thereby preventing the hydraulic oil from flowing out from the gap between the threaded rod 31 and the base plate 2 when the piston plate 9 presses the hydraulic oil in the water storage tank 8 into the piston groove 6. When the piston plate moves forward, the interior of the water storage tank 8 exchanges air with the outside through the gap between the circular rod and the inner wall of the circular hole, so as to prevent the appearance of a high pressure chamber or a negative pressure chamber in the water storage tank 8 during the sliding process of the piston plate 9 in the water storage tank 8, which would affect the sliding of the piston plate 9 in the water storage tank 8. It should be noted that a connecting hole may also be provided on the side of the base plate 2 away from the internal filling liquid, and the interior of the water storage tank 8 may exchange gas with the outside through the connecting hole.

[0023] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 4 and Figure 5 As shown, the connecting mechanism 4 includes an air storage tank 41, which is opened at the other end of the threaded rod 31. A piston plate 42 is slidably installed in the air storage tank 41. A threaded tube 43 is slidably installed in the opening of the air storage tank 41. One end of the threaded tube 43 is fixedly connected to the piston plate 42. The other end of the threaded tube 43 is provided with a threaded shaft 44. One end of the threaded shaft 44 is threaded into the threaded tube 43. The other end of the threaded shaft 44 is fixedly connected to the driving end of the driving mechanism 3 and rotatably connected to the slide rail 1. In this embodiment, please refer to Figure 2 , Figure 4 and Figure 5 As shown, after the bottom plate 2 is locked and positioned by the mutual contact between the piston rod 7 and the inner wall of the cone, the drive mechanism 3 continues to drive the threaded rod 31 to rotate in the opposite direction, thereby pulling part of the threaded rod 31 out of the air storage tank 41 and driving the piston plate 42 to slide together in the air storage tank 41, so that a negative pressure chamber of corresponding strength is formed in the air storage tank 41. Thus, the threaded rod 31 applies a corresponding pulling force to the filling liquid in the water outlet tank through the piston plate 9, and applies a corresponding thrust to the piston rod 7 through the hydraulic oil, so that the piston rod 7 and the inner wall of the conical groove 5 generate a corresponding contact force, making the locked state of the bottom plate 2 more stable.

[0024] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 4 and Figure 5 As shown, the cross-section of the opening of the gas storage tank 41 is square, the threaded pipe 43 is a square pipe, and the outer peripheral wall of the threaded pipe 43 is in contact with the inner wall of the opening of the gas storage tank 41. In this embodiment, please refer to Figure 2 , Figure 4 and Figure 5 As shown, when the driver 32 drives the threaded rod 31 to rotate in the forward direction through the connecting mechanism 4, the driving mechanism 3 drives the threaded shaft 44 to rotate in the forward direction. Due to the mutual contact between the threaded tube 43 and the inner wall of the opening of the air storage tank 41, the forward-rotating threaded shaft 44 first drives the threaded tube 43 to retract into the air storage tank 41 until the piston plate 42 and the inner wall of the air storage tank 41 come into contact with each other. At this time, the threaded tube 43 and the inner wall of the air storage tank 41 are stuck together, and the forward-rotating threaded shaft 44 drives the threaded rod 31 to rotate synchronously.

[0025] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, several receiving grooves 45 are symmetrically opened on the inner wall of the opening of the gas storage tank 41. A limiting groove 46 is opened on the outer wall of the threaded pipe 43 at the position corresponding to the receiving groove 45. A spring piece 47 is provided in the receiving groove 45. Both ends of the spring piece 47 are fixedly connected to the inner wall of the corresponding receiving groove 45, and the middle part of the spring piece 47 is inserted into the corresponding limiting groove 46. In this embodiment, please refer to Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, when the driver 32 drives the threaded rod 31 to rotate in the reverse direction through the connecting mechanism 4, the threaded shaft 44 first drives the threaded rod 31 to rotate in the reverse direction due to the mutual contact between the spring piece 47 and the inner wall of the limiting groove 46 and the mutual contact between the threaded tube 43 and the inner wall of the air storage tank 41. This continues until the frustum end of the piston rod 7 contacts the inner wall of the conical groove 5. At this time, the piston plate 9 can no longer press the hydraulic oil into the piston groove 6, that is, the position between the threaded rod 31, the piston plate 9 and the bottom plate 2 is fixed. At this time, due to the increased contact force between the outer arc surface of the spring piece 47 and the inner arc wall of the limiting groove 46, the spring piece 47 is pressed into the receiving groove 45 along the outer arc wall of the spring piece 47 to release the constraint and limiting state between the threaded tube 43 and the threaded rod 31. This allows the threaded shaft 44 to pull part of the threaded tube 43 out of the air storage tank 41. The device has a high degree of automation.

[0026] Working principle: When this improved reaming and burnishing integrated machine is in use, the base plate 2 is driven to slide in the slide rail 1 by the drive mechanism 3, thereby driving the workpiece to align with the reaming mechanism and the burnishing mechanism in sequence through the fixture, so as to complete the reaming and burnishing of the workpiece. After the position of the base plate 2 is adjusted, the piston rod 7 and the inner wall of the conical groove 5 abut against each other, and the position of the base plate 2 is automatically calibrated at the same time, and the position between the base plate 2 and the slide rail 1 is locked.

[0027] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
