Embodiment 1

[0023] Embodiment one: refer to Figure 1~3 , in an embodiment of the present invention, a casting finishing machine tool speed change gear structure, including a base 20 and a transmission shaft 8 connected to the output end of the motor, a speed change mechanism 1 is placed on the upper part of the base 20, to achieve multi-speed adjustment, control processing, close to The upper part of the base 20 of the transmission mechanism 1 is equipped with a cooling water tank 19, and the side end of the cooling water tank 19 is connected with a cooling water pipe 18, which is convenient for cooling the cutting part, and the cooling water can be recycled to save resources. 8 is provided with a driving bevel gear 9, the driving bevel gear 9 meshes with a driven bevel gear 10, the output end of the driven bevel gear 10 is connected to a crank shaft 11, and the crank shaft 11 is connected to a transmission rod 12 for rotation, and the transmission rod 12 is fixed. Connected on the conne...

Embodiment 2

[0030] Embodiment 2: The invention also provides another embodiment, which is improved on the basis of the above-mentioned embodiment. The support frame 7 is provided with a through groove 13, and the width of the through groove 13 is larger than that of the transmission The thickness of the rod 12 avoids interfering with the movement of the transmission rod 12.

[0031] In summary, when the invention works, the casting 21 is clamped and fixed by the fixed support one 3 and the fixed support two 14, which is convenient to operate and is suitable for castings 21 of different sizes. At this time, the transmission shaft 8 under the motor drive Under the transmission of the driving gear 5, the driven gear 6 and the gear ring 22, the rotation direction of the casting 21 and the grinding knife 4 is opposite, greatly improving the machining efficiency and quality of the grinding knife 4 cutting the inner wall of the casting 21, and, by Under the transmission of the active bevel gear ...

Abstract

The invention discloses a variable-speed gear structure of a casting finishing machine tool, and relates to the technical field of casting machining. The variable-speed gear structure comprises a baseand a transmission shaft connected to an output end of a motor, wherein a variable-speed mechanism is arranged on the upper part of the base, a driving bevel gear is arranged on the transmission shaft, a driven bevel gear is engaged with the driving bevel gear in a transmission mode, a crankshaft is connected to an output end of the driving bevel gear, a transmission rod is rotatably connected tothe crankshaft, the transmission rod is fixedly connected to a connecting part, the connecting part is connected with a connecting shaft through a bearing, a grinding cutter is arranged at the otherend of the connecting shaft, and a driving gear is connected to the transmission shaft through a key. Under the transmission of the transmission shaft, the driving gear, a driven gear and a gear ring,the rotation direction of a casting and the grinding cutter is opposite, the machining efficiency and quality of the grinding cutter for casting inner wall cutting are greatly improved, the left andright reciprocating movement of the grinding cutter is achieved through the transmission of the crankshaft and other assemblies, the grinding and machining quality of the casting is greatly improved by multi-group movement combination, and the machining accuracy is ensured.

Description

technical field [0001] The invention relates to the technical field of casting processing, in particular to a speed change gear structure of a casting finishing machine tool. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into the pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is polished and other subsequent processing methods Finally, the obtained object has a certain shape, size and performance. Castings have a long history of application. As early as 5,000 years ago, our ancestors were able to cast copper and bronze products. Casting is the most widely used metal liquid forming process. With the continuous development and progress of science and technology, today's casting technology pursues greater flexibility and wide adaptability, and is better applied to the processing and manufacturing of various mechanical parts. ...
