Description

Technical Field

[0001] This utility model relates to the field of grinding device technology, specifically a grinding device for processing internal gear rings with anti-splash function. Background Technology

[0002] The internal gear ring refers to the internal gear on the same axis as the planet carrier in a planetary gear transmission.

[0003] Application number CN202021053502.8 relates to a grinding device, particularly a splash-proof grinding device for train wheel surfaces, including a worktable and a splash-proof box. This utility model uses a splash-proof box to solve the problem that in general grinding devices, friction between the grinder and the wheel hub causes a large amount of iron filings to fly out, significantly impacting workers and the surrounding environment. In practical use, this application often results in a situation where, when two splash-proof boxes are combined, the grinding plate that moves with the splash-proof boxes cannot contact the object to be ground, making grinding impossible. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A grinding device for machining internal gear rings with anti-splash function includes an anti-splash mechanism, a grinding mechanism, and a rotating mechanism. The anti-splash mechanism includes a top plate, two side plates installed on both sides of the top plate, a threaded rod movably connected between the two side plates, a motor connected between one side plate and the threaded rod, and two housings connected to the threaded rod. The two housings are arranged opposite each other and fit against the top of the top plate. The grinding mechanism includes a U-shaped plate installed on the outside of the housing, a horizontal plate slidably connected between the housing and the U-shaped plate, a plug detachably connected between the U-shaped plate and the horizontal plate, two springs embedded in the inner end of the horizontal plate, a T-shaped rod connected to the outer end of the spring, and a grinding block connected between the two T-shaped rods. The T-shaped rod slides through the inner end of the horizontal plate, and the horizontal plate has multiple slots suitable for plug insertion. The rotating mechanism includes a tightening sleeve fitted against the top of the top plate and a motor connected between the top plate and the tightening sleeve.

[0007] By adopting the above technical solution, the insert can be removed, allowing the horizontal plate to be moved horizontally. The horizontal plate then moves the grinding block via springs and T-shaped rods. When the grinding block is closer to the object to be ground than the cross-section of the housing, the insert is reinserted, and then motor one is started. The threaded rod causes the two housings to move closer together. After the two housings are closed, the grinding block, under the pressure of the T-shaped rod and springs, fits tightly against the object to be ground. Then motor two is started, rotating the expansion sleeve with a fixed internal gear ring, thus realizing the grinding operation. Because the position of the grinding block can be flexibly adjusted, the grinding block can contact the object to be ground before the two housings are closed. This effectively enables the device to grind items of any size, improving the applicability of the device.

[0008] In a preferred embodiment, the present invention can be further configured such that the threads on the threaded rod are set in two segments with opposite directions of rotation.

[0009] In a preferred embodiment, the present invention can be further configured such that: multiple sockets on the horizontal plate are equally spaced and arranged in a row, and the distance between two adjacent sockets is equal to the width of the top of the U-shaped plate.

[0010] In a preferred embodiment, the present invention can be further configured such that: a short shaft is integrally formed on the top of the U-shaped plate, and the short shaft slides through the top of the plug-in.

[0011] In a preferred embodiment, the present invention can be further configured such that a guide rod is connected between the two side plates, and the cover is slidably sleeved on the outside of the guide rod.

[0012] In a preferred embodiment, this invention can be further configured such that bearings are sleeved at both ends of the threaded rod, and the bearings are embedded inside the side plate.

[0013] In a preferred embodiment, the present invention can be further configured such that: a base frame is installed at the bottom of the top plate, and the motor body is fixedly connected to the top of the base frame.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this utility model, by removing the insert, the horizontal plate can be moved horizontally. Then, the horizontal plate moves the grinding block via springs and T-shaped rods. When the grinding block is closer to the object to be ground than the cross-section of the housing, the insert is reinserted, and then motor one is started. The threaded rod affects the two housings to move closer together. After the two housings are closed, the grinding block, under the compression of the T-shaped rod and springs, fits tightly against the object to be ground. Then, motor two is started, and motor two rotates the expansion sleeve with the fixed internal gear ring, thereby realizing the grinding operation. Because the position of the grinding block can be flexibly adjusted, the grinding block can contact the object to be ground before the two housings are closed. This effectively enables this device to grind items of any size, improving the applicability of this device.

[0016] 2. In this utility model, after the inner toothed ring is fitted on the outer side of the expansion sleeve, the motor is started, and then the threaded rod affects the translation of the two housings. Under the guidance of the guide rod, the two housings close smoothly, which can block the iron filings generated when the inner toothed ring is polished, thus improving the safety of the device.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0030] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0031] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a grinding device for machining internal gear rings with anti-splash function.

[0032] Example 1:

[0033] Combination Figure 1-5 As shown, the present invention provides a grinding device for processing internal gear rings with anti-splash function, including an anti-splash mechanism 100, a grinding mechanism 200 and a rotating mechanism 300. The anti-splash mechanism 100 includes a top plate 110, two side plates 120 installed on both sides of the top plate 110, a threaded rod 130 movably connected between the two side plates 120, a motor 140 connected between one side plate 120 and the threaded rod 130, and two housings 150 connected to the threaded rod 130. The two housings 150 are arranged opposite each other and fit against the top of the top plate 110.

[0034] A polishing mechanism 200 includes a U-shaped plate 210 installed on the outside of the housing 150, a horizontal plate 220 slidably connected between the housing 150 and the U-shaped plate 210, an insert 230 detachably connected between the U-shaped plate 210 and the horizontal plate 220, two springs 240 embedded in the inner end of the horizontal plate 220, a T-shaped rod 250 connected to the outer end of the springs 240, and a polishing block 260 connected between the two T-shaped rods 250. The T-shaped rod 250 slides through the inner end of the horizontal plate 220, and the horizontal plate 220 has multiple slots suitable for inserting the insert 230.

[0035] The rotating mechanism 300 includes an expansion sleeve 310 that fits against the top of the top plate 110 and a motor 320 connected between the top plate 110 and the expansion sleeve 310.

[0036] Furthermore, the threads on the threaded rod 130 are configured as two segments with opposite directions of rotation. The structural design of the threaded rod 130 provides the conditions for the two housings 150 to close together, thus providing the conditions for realizing the splash-proof function.

[0037] Furthermore, the multiple sockets on the horizontal plate 220 are equally spaced and arranged in a row, with the distance between two adjacent sockets being equal to the width of the top of the U-shaped plate 210. The socket layout design allows the horizontal plate 220 to be flexibly fixed after translation.

[0038] Furthermore, the top of the U-shaped plate 210 is integrally formed with a short shaft, which slides through the top of the plug-in 230. The short shaft can fix the plug-in 230 and prevent the plug-in 230 from loosening at will.

[0039] Furthermore, a base frame 600 is installed at the bottom of the top plate 110, and the body of the second motor 320 is fixedly connected to the top of the base frame 600. The base frame 600 can lift the device and also fix the second motor 320, so that the second motor 320 can smoothly rotate with the expansion sleeve 310.

[0040] Example 2:

[0041] Combination Figure 1 As shown, based on Embodiment 1, a guide rod 400 is connected between the two side plates 120, and the housing 150 is slidably sleeved on the outside of the guide rod 400. The guide rod 400 is provided to guide the housing 150 and ensure that the two housings 150 can be closed smoothly.

[0042] Example 3:

[0043] Combination Figure 1 and Figure 5 As shown, in the above embodiment, bearings 500 are sleeved at both ends of the threaded rod 130. The bearings 500 are embedded inside the side plate 120. The bearings 500 can improve the stability of the threaded rod 130 when it rotates.

[0044] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the internal gear ring is placed on the outside of the expansion sleeve 310, then the insert 230 is removed, and the horizontal plate 220 is moved horizontally. Then, the horizontal plate 220 moves the grinding blocks 260 through the spring 240 and the T-shaped rod 250. When the distance between the two grinding blocks 260 is less than the distance between the two housings 150, the insert 230 is reinserted, and then the horizontal plate 220 is fixed. Then, the motor 140 is started, and the threaded rod 130 affects the two housings 150 to move closer together. During the process, the two grinding blocks 260 move together and first come into contact with the inner gear ring. Then the threaded rod 130 continues to rotate. When the two covers 150 close, the grinding blocks 260 will squeeze the T-shaped rod 250, and then the spring 240 will contract. This allows the grinding blocks 260 to come into close contact with the inner gear ring. Then the motor 220 is started. The motor 220 rotates the inner gear ring through the expansion sleeve 310, thereby completing the grinding of the outer wall of the inner gear ring. The iron filings generated during the grinding operation are blocked by the cover 150, achieving the function of preventing splashing.

[0045] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
