Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a flange broach fixing frame. Background Art

[0002] The flange broach holder is a device used to fix flange broaches. The main function of the flange broach holder is to provide stable support and fixation for the broach during the broach sharpening process to ensure the accuracy and quality of sharpening. The design of the flange broach holder usually takes into account the operator's convenience of use and can improve work efficiency.

[0003] The flange broach fixing frame in the prior art has a simple structure, and the flange broach is basically connected by a clamping connection: the broach is fixed to the fixing frame by a clamping device, and the clamping device can be a bolt, a nut, a pressure plate, etc. There is also a welding connection: the handle or the shank of the broach is welded together with the fixing frame. This connection method is relatively strong, but it is not convenient for disassembling and replacing the broach. The clamping connection requires frequent operation and tightening of bolts, nuts and other clamping devices during disassembly and assembly, which is rather cumbersome, especially when the broach needs to be replaced frequently, which will consume a lot of time and energy. After the welding connection, it is basically non-removable. Once the broach needs to be replaced or other adjustments need to be made to the broach, it is very difficult, and it may even be necessary to destroy the welded part. In order to address this problem, a flange broach fixing frame is proposed herein. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A flange broach fixing frame includes a fixing block 1 connected to a hydraulic cylinder, a plurality of connecting holes 2 are arranged on the fixing block 1, a broach body 4 is installed in each connecting hole 2, a transmission chamber 7 and a rotating chamber 10 are arranged inside the fixing block 1, a driving motor 8 is installed in the transmission chamber 7, a screw rod 11 extending into the transmission chamber 7 is arranged for rotation in the rotating chamber 10, and only a portion of the screw rod 11 in the rotating chamber 10 is provided with threads, and the direction of the threads is arranged correspondingly according to the direction of the screw rod 11, so as to ensure that three nuts 13 are approached or moved away at the same time.

[0021] The screw rod 11 is connected to the driving motor 8 through a transmission mechanism, and a nut 13 is threadedly sleeved on the screw rod 11, and the nut 13 is connected to the broach body 4 through an insertion mechanism. The main components of the flange broach fixing frame include a fixing block 1, a connecting hole 2, the broach body 4, a transmission chamber 7, a rotating chamber 10, a driving motor 8, a screw rod 11, a nut 13 and an insertion mechanism. The fixing block 1 is connected to the hydraulic cylinder for fixing. The connecting hole 2 is used to install the broach body 4, and the driving motor 8 in the transmission chamber 7 drives the screw rod 11 to rotate through the transmission mechanism, so that the nut 13 moves on the screw rod 11, and the nut 13 is connected to the broach body 4 through the insertion mechanism to achieve the fixing and movement of the broach body 4.

[0022] The transmission mechanism includes a driving gear 9 installed on the output shaft of the driving motor 8, and a transmission gear 12 is installed on the screw 11. The driving gear 9 is meshed with the transmission gear 12. When the driving motor 8 rotates, the driving gear 9 drives the transmission gear 12 to rotate, thereby rotating the screw 11.

[0023] The plug-in mechanism includes a positioning rod 3 installed on the nut 13, and a positioning hole 5 corresponding to the positioning rod 3 is provided on the broach body 4. The positioning hole 5 is set on the broach body 4. When the nut 13 moves on the screw 11, the positioning rod 3 moves accordingly. When the positioning rod 3 is inserted into the positioning hole 5, the broach body 4 is fixed on the fixed block 1. The positioning rod 3 slides through the inner wall of the rotating cavity 10 and extends into the connecting hole 2. Therefore, it has its own limit to prevent the nut 13 from rotating with the screw 11.

[0024] The driving gear 9 and the transmission gear 12 are both bevel gears, and the driving gear 9 and the transmission gear 12 are vertically meshed, which can realize vertical transmission. The driving gear 9 and the transmission gear 12 are vertically meshed, and this meshing method can make the transmission more stable.

[0025] The positioning rod 3 slides through the inner wall of the rotating cavity 10 and extends into the connecting hole 2. A slot 6 corresponding to the positioning rod 3 is also provided on the inner wall of the connecting hole 2. When the positioning rod 3 is inserted into the slot 6, the fixing effect of the broach body 4 can be further enhanced. At the same time, three equipment components corresponding to the connecting hole 2 are arranged and are evenly spaced circumferentially.

[0026] The number of the connecting holes 2 is three, and the three connecting holes 2 are evenly spaced around the circumference, which can meet the use requirements in most cases. The three connecting holes 2 are evenly spaced around the circumference, and this distribution method can make the broach body 4 evenly stressed on the fixing block 1, avoiding local deformation or damage caused by uneven stress.

[0027] When the utility model is used, when the driving motor 8 is working, the driving gear 9 on its output shaft drives the transmission gear 12 meshing therewith to rotate. Since the transmission gear 12 is installed on the screw 11, the screw 11 is rotated in the rotating chamber 10. The rotation of the screw 11 will move the nut 13 threaded thereon, and the positioning rod 3 on the nut 13 will move accordingly. When it is necessary to fix the broach body 4, the positioning rod 3 is inserted into the positioning hole 5 on the broach body 4 and the slot 6 on the inner wall of the connecting hole 2 to fix the broach body 4 in the connecting hole 2. In this way, the broach body 4 can be easily installed and fixed, and the three connecting holes 2 are evenly spaced circumferentially, which ensures that the broach body 4 is subjected to uniform and stable force. The vertical meshing mode of the driving gear 9 and the transmission gear 12 and the design of the bevel gear also ensure the smoothness of the transmission.

[0028] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
