Description

Technical Field

[0001] This application relates to the technical field of bolt processing devices, and in particular to a rust removal and polishing device for hydraulic torque converter bolts. Background Technology

[0002] The torque converter is a crucial component of an automatic transmission in automobiles. Its functions are twofold: first, to transmit speed and torque; and second, to make the connection between the engine and the automatic transmission non-rigid, facilitating automatic gear shifting. During use, the external bolts of the torque converter can corrode due to daily wear and tear.

[0003] When cleaning the rust on the bolts of a hydraulic torque converter, the rusted areas inside the bolt thread grooves are not easy to clean. Workers usually need to manually remove the rust one by one. After a long time of polishing, this method causes great hand fatigue and makes it impossible to continuously provide the pressure required for polishing with sandpaper.

[0004] Therefore, those skilled in the art have provided a rust removal and polishing device for hydraulic torque converter bolts to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a rust removal and polishing device for hydraulic torque converter bolts.

[0006] The rust removal and polishing device for hydraulic torque converter bolts provided in this application adopts the following technical solution:

[0007] A rust removal and polishing device for hydraulic torque converter bolts includes a base plate. Two inner vertical plates are symmetrically installed on both sides of the upper surface of the base plate. A first limiting post and a second limiting post are rotatably installed on opposite sides of the two inner vertical plates. The end face of the first limiting post is provided with a hexagonal slot. A second motor is installed on the side of the inner vertical plate on the same side as the first limiting post. The output end of the second motor is fixed to the corresponding end of the first limiting post. Outer vertical plates are installed on both sides of the upper part of the base plate. A drive mechanism is provided between the tops of the two outer vertical plates to control the movement of the two inner vertical plates towards each other or away from each other.

[0008] A support plate is fixedly connected between the bottom of the two outer uprights, and the support plate passes through the bottom of the two inner uprights. Two adjusting plates are sleeved on the outside of the support plate, and a polishing mechanism is installed between the tops of the two adjusting plates.

[0009] Preferably, the polishing mechanism includes a pad installed between the tops of two adjusting plates, with a sponge pad adhered to the upper surface of the pad and sandpaper adhered to the upper surface of the sponge pad.

[0010] Preferably, a fixing plate is fixedly connected between the two sides of the adjusting plates, and a limit bolt is threadedly connected at the center of the fixing plate, with one end of the limit bolt inserted into the side of the support plate.

[0011] Preferably, the support plate has multiple insertion holes equidistantly spaced on its side.

[0012] Preferably, the driving mechanism includes a bidirectional lead screw rotatably mounted between the tops of the two outer panels, with both inner panels being helically driven by both sides of the bidirectional lead screw, and a No. 1 motor mounted on the side of one of the outer panels, the output end of which is fixed to the corresponding end of the bidirectional lead screw.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] The No. 1 motor drives the bidirectional lead screw to rotate, which in turn moves the two inner vertical plates, causing the No. 1 and No. 2 limit posts to move. This clamps and limits the bolt between the No. 1 and No. 2 limit posts. In conjunction with the No. 2 motor, the rotating No. 1 limit post works with the No. 2 limit post to continuously rotate the clamped bolt, causing the bolt thread end to continuously contact the sandpaper, thus achieving automatic polishing of the bolt. Compared to manual polishing, this method can effectively reduce the fatigue of the operator's hands during polishing, continuously provide the sandpaper with the necessary force during polishing, and ensure the polishing effect.

[0019] 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.

[0020] refer to Figures 1-3 As shown, this application discloses a rust removal and polishing device for hydraulic torque converter bolts, including a base plate 1, which is mounted on a processing table. Two inner vertical plates 4 are symmetrically installed on both sides of the upper surface of the base plate 1. A first limiting post 5 and a second limiting post 7 are rotatably installed on opposite sides of the two inner vertical plates 4. The end face of the first limiting post 5 has a hexagonal slot to facilitate the engagement of bolt nuts in the hexagonal slot. The rotatable first limiting post 5 can drive the bolt to rotate. A second limiting post 7 is installed on the side of the inner vertical plate 4 on the same side as the first limiting post 5. Motor 15, and the output end of the second motor 15 is fixed to the corresponding end of the first limit post 5. Both sides of the upper part of the base plate 1 are equipped with outer plates 3. A drive mechanism is provided between the top of the two outer plates 3 to control the movement of the two inner plates 4 towards each other or away from each other. The two inner plates 4 move towards each other through the drive mechanism. Then, the two inner plates 4 moving towards each other drive the first limit post 5 and the second limit post 7 to move synchronously, clamping and limiting the bolt between the first limit post 5 and the second limit post 7, which facilitates the limiting of the bolt before polishing.

[0021] refer to Figure 1 and Figure 2 As shown, the polishing mechanism includes a pad 14 installed between the tops of two adjusting plates 13. A sponge pad 10 is adhered to the upper surface of the pad 14, and sandpaper 9 is adhered to the upper surface of the sponge pad 10, so that the sandpaper 9 can be elastically squeezed with the bolt, increasing the friction on the bolt and ensuring the polishing effect on the bolt.

[0022] refer to Figure 1 and Figure 2 As shown, a fixed plate 12 is fixedly connected between the two sides of the adjusting plates 13. A limit bolt 11 is threadedly connected at the center of the fixed plate 12, and one end of the limit bolt 11 is inserted into the side of the support plate 8 to facilitate the position adjustment of the sandpaper 9, change the grinding position of the bolt, and avoid the occurrence of dead angles in the polishing of the bolt.

[0023] refer to Figure 1 and Figure 2 As shown, the support plate 8 has multiple insertion holes equidistantly arranged on its side, which facilitates the sandpaper 9 to be inserted into the corresponding insertion hole after its position is adjusted by the limiting bolt 11, thereby limiting the position of the sandpaper 9 after adjustment.

[0024] refer to Figure 1 As shown, the drive mechanism includes a bidirectional lead screw 6 rotatably mounted between the tops of the two outer vertical plates 3, and both inner vertical plates 4 are screwed to both sides of the bidirectional lead screw 6. A No. 1 motor 2 is mounted on the side of one outer vertical plate 3, and the output end of the No. 1 motor 2 is fixed to the corresponding end of the bidirectional lead screw 6.

[0025] By starting motor 2, the bidirectional lead screw 6 is driven to rotate, causing the inner plates 4 on both sides to move towards each other. Then, the two inner plates 4 moving towards each other drive the first limiting post 5 and the second limiting post 7 to move synchronously, clamping and limiting the bolt between the first limiting post 5 and the second limiting post 7, which facilitates the subsequent polishing of the bolt.

[0026] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] The implementation principle of the hydraulic torque converter bolt rust removal and polishing device in this application embodiment is as follows:

[0029] During processing, the bolt nut end is engaged in the hexagonal slot on the end face of the first limiting post 5. Then, the first motor 2 is started, driving the bidirectional lead screw 6 to rotate, causing the two inner vertical plates 4 to move towards each other. The two inner vertical plates 4 moving towards each other then drive the first limiting post 5 and the second limiting post 7 to move synchronously, clamping and limiting the bolt between the first limiting post 5 and the second limiting post 7. Next, the adjusting plate 13 is moved to the position outside the support plate 8, so that the lower part of the bolt is pressed against the sandpaper 9. This works in conjunction with the rotation of the limiting bolt 11, which is inserted into the side of the support plate 8, limiting the adjusting plate 13. Finally, the second motor 15 is started, driving the first limiting post 5 to rotate. The rotating first limiting post 5 then works with the second limiting post 7 to continuously rotate the clamped and limited bolt, causing the bolt thread end to continuously contact the sandpaper 9, thus polishing the bolt. Compared with manual polishing, this method can effectively reduce the fatigue of the operator's hands during polishing, while ensuring the polishing effect.
