[0002] The internal gear ring is an internal gear on the same axis as the planet carrier in a planetary gear transmission. As an important transmission component in a planetary gear transmission system, the internal gear ring is responsible for transmitting rotational power from the planetary gears to the external gears, thereby realizing the transformation of speed and the transmission of torque.

[0003] In existing internal gear ring machining, the internal gear ring is fixed by a clamping device on the worktable. After fixing, the gear ring is machined. However, the gear ring machining generates a large amount of iron filings and cutting oil. The iron filings accumulate on the worktable, causing them to embed into the workpiece surface, resulting in surface scratches or machining defects, reducing the machining quality of the workpiece. In addition, the machine needs to be stopped to clean the iron filings, which increases auxiliary time and reduces the overall machining efficiency.

[0004] Therefore, it is necessary to provide a new clamping device for internal gear ring gear shaping to solve the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of a preferred embodiment of a clamping device for inserting internal gear rings provided by this utility model; Figure 2 for Figure 1 The diagram shows the front structure. Figure 3 for Figure 1 The diagram shows a top view of the structure. A clamping device for inserting internal gear rings includes a separation chamber 1. Each of the four side walls of the separation chamber 1 is provided with an L-shaped support plate 2. A first support plate 3 is slidably and laterally arranged on the top of each L-shaped support plate 2. A vertical plate 5 is provided on the front side of the top of each first support plate 3. A fixing plate 4 for fixing the internal gear ring is provided on the inner side of each vertical plate 5.

[0021] The four first support plates 3 and each fixed plate 4 form a clamping device for fixing the internal gear ring.

[0022] The first support plate 3 is movable and can be used to process internal gear rings of different sizes.

[0023] A filter screen 7 is horizontally arranged above the inner cavity of the separation chamber 1. A push plate 8 is movably arranged on one side of the separation chamber 1 to push out iron filings from the surface of the filter screen 7. A slag discharge port 9 is opened on the other side of the separation chamber 1 and is flush with the push plate 8. A sealing plate 10 for sealing the slag discharge port 9 is removably arranged inside the slag discharge port 9.

[0024] Filter 7 is used to separate iron filings and cutting oil that occur during the gear hobbing of internal gear rings.

[0025] The push plate 8 is used to push out iron filings from the surface of the filter screen 7 to prevent iron filings from accumulating too high and interfering with the normal operation of the internal gear ring.

[0026] The sealing plate 10 is used to seal the slag discharge port 9 to prevent cutting oil from flowing out of the slag discharge port 9 during operation.

[0027] When it is necessary to remove iron filings from the surface of the filter screen 7, the iron filings can be removed from the filter screen 7 by driving the sealing plate 10 away from the slag discharge port 9 and driving the push plate 8 again, thus avoiding accumulation.

[0028] Each of the vertical plates 5 has a vertically opening receiving groove 6, and a lead screw 22 is rotatably installed in the receiving groove 6. A threaded sleeve 18 is threadedly connected to the surface of the lead screw 22, and the fixing plate 4 is fixedly connected to the surface of the threaded sleeve 18.

[0029] A handle is fixedly connected to the top of the lead screw 22 and extending to the top of the vertical plate 5.

[0030] When it is necessary to fix or release the internal gear ring, the handle is rotated to drive the lead screw 22 to rotate. Since the threaded sleeve 18 is threadedly engaged with the lead screw 22, rotating the lead screw 22 will drive the threaded sleeve 18 to move up and down on the lead screw 22. The movement of the threaded sleeve 18 will drive the fixing plate 4 to move up and down, thereby fixing or releasing the internal gear ring.

[0031] A second support plate 12 is horizontally arranged on one side of the separation chamber 1, and a first electric telescopic rod 13 is horizontally arranged on the upper surface of the second support plate 12. The push plate 8 is fixedly connected to one end of the first electric telescopic rod 13.

[0032] When it is necessary to push out the iron filings on the surface of the filter screen 7, the first electric telescopic rod 13 is activated to extend, thereby driving the push plate 8 to move along the surface of the filter screen 7, thus pushing the iron filings on the surface of the filter screen 7 to the outside of the slag discharge port 9.

[0033] A third support plate 14 is arranged laterally on the other side of the separation chamber 1. A bracket is provided on the rear side of the upper surface of the third support plate 14. A second electric telescopic rod 15 is provided on the bracket. The sealing plate 10 is fixedly connected to one end of the second electric telescopic rod 15.

[0034] When it is necessary to remove iron filings from the surface of the filter screen 7, the second electric telescopic rod 15 is activated to move the sealing plate 10 away from the slag discharge port 9.

[0035] After the iron filings are discharged, the blocking plate 10 is moved by driving it until it fits against the slag discharge port 9, ensuring that the slag discharge port 9 is blocked and preventing cutting oil from flowing out of the slag discharge port 9.

[0036] The upper surface of the third support plate 14 is detachably provided with a collection frame 16 for collecting iron filings, and a second guide plate 20 is provided on the side wall of the separation chamber 1 and below the slag discharge port 9. The bottom of the separation chamber 1 is provided with a discharge port 11.

[0037] The separated cutting oil is discharged through outlet 11 and enters an external collection or treatment system.

[0038] The second guide plate 20 is used to guide the iron filings to fall smoothly into the collection frame 16.

[0039] The first support plate 3 is hinged to the top of the separation chamber 1 with a first guide plate 17 at its front end. The bottom of the first support plate 3 is fixedly connected with a connecting plate 21. The inner end of each L-shaped support plate 2 is fixedly connected with a third electric telescopic rod 19. The surface of the connecting plate 21 is fixedly connected to one end of the third electric telescopic rod 19.

[0040] The first guide plate 17 is a telescopic plate. When the first support plate 3 moves, the tilt angle of the first guide plate 17 can be changed to ensure that the iron filings can fall into the separation chamber 1 for separation.

[0041] The first guide plate 17 is used to guide the iron filings and cutting oil generated during the machining of the internal gear ring, ensuring that they fall into the separation chamber 1.

[0042] When it is necessary to process internal gear rings of different sizes, the third electric telescopic rod 19 is activated to extend or shorten, thereby driving the connecting plate 21 to move. Since the connecting plate 21 is fixedly connected to the first support plate 3, the first support plate 3 is driven to move, thus allowing internal gear rings of different sizes to be placed.

[0043] The working principle of the clamping device for internal gear ring gear fitting provided by this utility model is as follows:

[0044] When it is necessary to perform gear shaping on the internal gear ring, first adjust the position of the four first support plates 3 to ensure the size of the internal gear ring to be used. Then place the internal gear ring on the four first support plates 3 and fix it by driving the fixing plate 4. After fixing, start the gear shaping equipment to process it. A large amount of iron filings and cutting oil will be generated during the processing. The iron filings and cutting oil will fall into the separation chamber 1 for separation by the first guide plate 17. After accumulating to a certain height on the filter screen 7, the iron filings will flow into the collection frame 16 for collection by the cooperation of the drive push plate 8 and the sealing plate 10, so as to avoid the iron filings accumulating on the worktable and causing unnecessary impact. After processing is completed, the fixing plate 4 can be released from fixing the internal gear ring.

[0045] Compared with related technologies, the clamping device for internal gear ring gear fitting provided by this utility model has the following advantages:

[0046] This utility model provides a clamping device for internal gear ring gear shaping. The internal gear ring is fixed by a drive fixing plate 4. After fixing, the gear shaping equipment is started to process it. During the processing, a large amount of iron filings and cutting oil are generated. The iron filings and cutting oil fall into the separation chamber 1 for separation by the first guide plate 17. After accumulating to a certain height on the filter screen 7, the iron filings flow into the collection frame 16 for collection by the cooperation of the drive push plate 8 and the sealing plate 10. There is no need to stop the machine to clean the iron filings, thereby reducing processing interruptions, improving overall production efficiency, reducing workpiece surface scratches or processing defects caused by iron filings, and improving workpiece quality.
