Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and in particular to a positioning device for deburring the inner wall of a cylinder. Background Technology

[0002] As a key component in a mechanical system, the precision of the cylinder's internal structure directly affects the performance and lifespan of the entire system. The core component of a cylinder is a central shaft, which typically has multiple holes punched on it. The size and location of these holes are determined by specific design requirements. The presence of these holes enables the cylinder to perform functions such as fluid control and pressure regulation; therefore, the machining quality of these holes is of paramount importance.

[0003] Punching is a crucial step in shaft manufacturing. Because punching is done from the outside in, burrs remain on the inner wall of the hole. These burrs not only affect the fit between the shaft and other components but can also cause uneven fluid flow, thus impacting cylinder performance. Removing these burrs typically requires grinding or other post-processing steps. For larger holes, burr removal is relatively easy because the larger space allows tools to enter and process them more easily. However, for smaller holes, burr removal is more difficult because the limited space makes traditional mechanical grinding methods ineffective. Currently, the industry commonly uses electrolytic flushing to remove burrs from small holes. Through the action of the electrolyte, the burrs are gradually melted and removed.

[0004] However, existing deburring processes have some significant drawbacks. First, to ensure alignment between the small holes and the electrolytic rinsing positions, a large hole is typically used as a reference for positioning. This process requires manually rotating the central shaft of the cylinder to ensure that each small hole is accurately aligned with the rinsing position. Manual operation is not only inefficient but also makes it difficult to guarantee the accuracy of alignment each time, resulting in inconsistent processing quality. Furthermore, manual operation is prone to introducing human error, further affecting the deburring effect. Utility Model Content

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0024] This embodiment mainly describes the structure of the positioning device, as follows:

[0025] A positioning device for deburring the inner wall of a cylinder, such as Figures 1-5 As shown, the system includes a worktable 1, a protective cover 2, molds 3, a baffle 4, a mounting bracket 5, an electric push rod 6, a motor 7, a turntable 8, a push rod 9, a first elastic element 10, a pressure sensor 11, and a controller 111. The protective cover 2 is mounted on the worktable 1. Six molds 3 are mounted on the worktable 1, with a central shaft sleeved on each mold 3. An electric push rod 6 is mounted on the worktable 1. The piston rod of the electric push rod 6 faces rearward and is fixedly connected to the mounting bracket 5. A baffle 4 is fixedly connected to the rear side of the mounting bracket 5. The baffle 4 is slidably connected to the worktable 1. Six push rods 9 are slidably connected inside the baffle 4. A first elastic element 10 is sleeved on each push rod 9. One end of the rod 0 is fixedly connected to the push rod 9, and the other end is fixedly connected to the baffle 4. The first elastic element 10 is in a stretched state, and a pressure sensor 11 is installed inside the mounting bracket 5. The push rod 9 passes through the pressure sensor 11, and the push rod 9 and the pressure sensor 11 are pressed together. A controller 111 is installed on the front side of the mounting bracket 5. The electric push rod 6 is wired to the controller 111. Six motors 7 are installed at the bottom of the mounting bracket 5. The output shaft of the motor 7 faces downward and is fixedly connected to a turntable 8. The turntable 8 passes through the baffle 4 and contacts the side of the central shaft. The controller 111 is wired to the motor 7 and the pressure sensor 11. Each pressure sensor 11 is matched with the motor 7 at its bottom.

[0026] like Figure 3 and Figure 4 As shown, it also includes a fixed plate 12, an extrusion member 13, and a second elastic member 14. The fixed plate 12 is fixedly connected to the top of the baffle 4, and the extrusion member 13 is slidably connected below the fixed plate 12. The extrusion member 13 is extruded and fitted with the top of the central shaft. The second elastic member 14 is sleeved on the extrusion member 13. One end of the second elastic member 14 is fixedly connected to the fixed plate 12, and the other end is fixedly connected to the extrusion member 13.

[0027] like Figure 3 and Figure 4 As shown, it also includes a sponge pad 15, which is connected to the bottom side of the extruder 13. The sponge pad 15 contacts the top of the central shaft during the extrusion process, playing a buffering and protective role, preventing damage to the surface of the central shaft due to extrusion, and ensuring uniform pressure distribution.

[0028] like Figure 5As shown, it also includes a protective ball 16. The rear end of the push rod 9 is rotatably connected to the protective ball 16. When the push rod 9 is inserted into the large hole, the protective ball 16 can adapt to the inner wall shape of the large hole, reduce the friction between the push rod 9 and the inner wall of the large hole, avoid scratching the inner wall of the central shaft, and improve the positioning accuracy.

[0029] like Figure 5 As shown, it also includes buffer balls 17. Six buffer balls 17 are rotatably connected to the bottom of the baffle 4. The buffer balls 17 contact the worktable 1 during the movement of the baffle 4, playing a role in buffering and shock absorption, reducing the impact force when the baffle 4 moves, and ensuring the smooth operation of the device.

[0030] like Figure 3 As shown, it also includes a rubber pad 18. The outer ring of the turntable 8 is fitted with a rubber pad 18. When the turntable 8 contacts the central shaft, the rubber pad 18 increases the friction, ensuring that the turntable 8 can effectively drive the central shaft to rotate, while avoiding direct contact between the turntable 8 and the central shaft, which would cause surface damage.

[0031] like Figure 1 As shown, it also includes a housing 19, which is fixedly attached to the worktable 1. The housing 19 covers the electric push rod 6 and the mounting bracket 5 to prevent external dust or foreign objects from entering the device, protect the operating environment of the electric push rod 6 and the mounting bracket 5, and extend the service life of the device.

[0032] like Figure 1 As shown, it also includes a placement rack 20. The placement rack 20 is fixed to the front side of the workbench 1. The placement rack 20 is used to temporarily store the central shaft that is to be processed or has been processed, so as to facilitate the staff to pick up and put it away and improve work efficiency.

[0033] The operator places the central shaft onto mold 3, which then slides down. After the device is activated via controller 111, the electric push rod 6 pushes the mounting bracket 5 and baffle 4 backward. Baffle 4 moves the push rod 9 closer to the central shaft. When the push rod 9 is not aligned with the large hole, the first elastic element 10 is further stretched, and the front end of the push rod 9 moves away from the pressure sensor 11. The pressure sensor 11 does not detect the compression signal from the push rod 9, thus determining that the rear end of the push rod 9 is not inserted into the large hole. Controller 111 receives the signal and activates motor 7. Motor 7 drives turntable 8 to rotate, increasing the contact friction through rubber pad 18, thereby causing turntable 8 to rotate the central shaft until the push rod 9 is aligned with the large hole. At this time, the first elastic element 10 contracts, pulling the push rod 9 into the large hole to complete the positioning. During the backward movement of the push rod 9, it is squeezed against the pressure sensor 11. The controller 111 shuts down the motor 7 corresponding to the pressure sensor 11. Subsequently, the electrolytic flushing device is started, and the liquid of the electrolytic flushing device enters the central shaft to remove the burrs on the inner side of the central shaft. After completion, the electric push rod 6 retracts, driving the mounting bracket 5 and the baffle 4 to reset. The staff then take out the processed central shaft.

[0034] As the electric push rod 6 pushes the mounting bracket 5 and the baffle 4 backward, the fixing plate 12 moves backward along with the baffle 4. The extrusion member 13 contacts the top edge of the central shaft through its bottom slope, applying downward pressure to ensure that the central shaft is firmly attached to the mold 3. The second elastic member 14 is compressed during the extrusion process. When the electric push rod 6 retracts, the second elastic member 14 pushes the extrusion member 13 back to its original position, relieving the pressure on the central shaft and making it easier for the operator to remove the central shaft.
