Description

Technical Field

[0001] The utility model relates to the technical field of guide roller processing, and particularly relates to an auxiliary fixing fixture for guide roller processing. Background Technique

[0002] During the processing of guide rollers, polishing treatment is required. Before polishing, a fixture is needed to clamp it for convenient processing. At present, the auxiliary fixing fixture for guide roller processing is usually a four-jaw chuck. When in use, the four-jaw chuck is stuck on the end of the guide roller, and the fixture carried by the instrument for polishing the guide roller is used to clamp the four-jaw chuck, so as to realize the clamping and fixing of the guide roller. However, during the use of the four-jaw chuck, it is necessary to adjust it multiple times to find the center point of the guide roller, which affects the clamping efficiency of the guide roller. When the four-jaw chuck tightens the guide roller, it is easy to damage the workpiece. Moreover, during the processing of the guide roller, due to the resistance of the tool, the guide roller may rotate automatically, affecting the processing of the guide roller. Based on this, this application proposes an auxiliary fixing fixture for guide roller processing. Content of the Utility Model

[0003] The utility model provides an auxiliary fixing fixture for guide roller processing, which solves the problems of multiple adjustments to find the center point, easy damage to the workpiece, time-consuming and laborious, and the automatic rotation of the guide roller due to the tool resistance when using a four-jaw chuck to assist in fixing the guide roller as mentioned in the above background technique.

A slot is provided in the middle of one end of the fixture body, and the slot is communicated with the inner cavity of the card hole. Both ends of the slot are fastened by bolts. A stop rod is fixedly connected to the other end of the fixture body.

[0005] Preferably, the direction of the stop rod is parallel to the straight line where the center of the card hole is located.

[0006] Preferably, the corners of the fixture body are provided with rounded corners. The fixture body and the stop rod are of an integrally formed structure, and the connecting part of the fixture body and the stop rod is provided with rounded corners.

[0007] Preferably, one end of the bolt is located outside the fixture body, and a screwing cap is connected to one end of the bolt.

[0008] Preferably, isolation pads are provided on the inner wall of the card hole and the outer surface of the stop rod.

[0009] Preferably, the thickness value of the fixture body is not less than the length value of the end of the guide roller.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Refer to Figures 1 to 4 , the present utility model provides an auxiliary fixing fixture for guide roller processing, including a fixture body 1. A clamping hole 4 adapted to the end of the guide roller is provided in the middle of the fixture body 1. A slot is provided in the middle of one end of the fixture body 1. The slot is communicated with the inner cavity of the clamping hole 4, and both ends of the slot are fastened by bolts 3. When the auxiliary fixing fixture is in use, the fixture body 1 can be sleeved on the end of the guide roller. After the fixture body 1 is sleeved on the end of the guide roller, the fixture is fastened by using the bolt 3, so that the fixture is fixed together with the end of the guide roller, as Figure 3 shown. One end of the bolt 3 is located outside the fixture body 1, and a screwing cap 5 is connected to one end of the bolt 3, which is convenient for the user to screw the bolt 3.

[0020] An isolation pad is fixed to the inner wall of the clamping hole 4. The isolation pad can be made of rubber. By setting the isolation pad, the clamp body 1 can be separated from the guide roller end, increasing the friction between the clamp body 1 and the guide roller end, preventing the guide roller from rotating during the processing, and protecting the guide roller end to avoid damage to the guide roller end.

[0021] The thickness of the clamp body 1 is not less than the length of the guide roller end. Preferably, the thickness of the clamp body 1 is the same as the length of the guide roller end. The thickness of the clamp body 1 can be set according to demand and is not limited here.

[0022] From the above description, it can be seen that when the auxiliary fixing clamp is used, the clamp body 1 is directly put on the end of the guide roller without finding the center point of the guide roller, which can greatly improve the clamping efficiency of the guide roller.

[0023] The other end of the fixture body 1 is fixedly connected to a stop rod 2, and the direction of the stop rod 2 is parallel to the straight line where the center of the clamping hole 4 is located. When the fixture is in use, the guide roller and the stop rod 2 are respectively located on both sides of the fixture body 1. During the polishing process of the guide roller, the stop rod 2 can be inserted into the chuck gap of the guide roller polishing lathe, such as Figure 4 As shown, the stop rod 2 can position the guide roller at this time, further preventing the workpiece from rotating due to the resistance of the tool during rotation processing, and maintaining the center stable while processing smoothly.

[0024] The clamp body 1 and the stop rod 2 are an integrally formed structure, which improves the strength of the fixing clamp. The corners of the clamp body 1 are provided with rounded corners, and the connection part between the clamp body 1 and the stop rod 2 is provided with rounded corners to reduce stress concentration and improve the strength of the fixing clamp.

[0025] The outer surface of the stop rod 2 is provided with an isolation pad, and the isolation pad can be made of rubber. By setting the isolation pad, the impact force when the stop rod 2 contacts the chuck can be reduced.

[0026] To sum up: when the auxiliary fixing fixture for guide roller processing is used, the user directly puts the fixture body 1 on the end of the guide roller and tightens it with the bolt 3, so that the fixture body 1 is fixed to the end of the guide roller. The staff moves the guide roller so that the stop rod 2 is placed in the chuck gap of the lathe. The center point of the guide roller is facing the top rod of the chuck of the guide roller polishing lathe. The other end of the guide roller is supported by the top rod of the tailstock of the rear lathe. The guide roller is fixed on the guide roller polishing lathe. When the chuck drives the guide roller to rotate, the stop rod 2 can limit the guide roller so that the guide roller will not rotate due to the resistance of the tool during rotation processing, keeping the center stable while processing smoothly.

[0027] All standard parts used in this utility model can be purchased from the market. Special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, which will not be elaborated here. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art. Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
