Problems solved by technology
[0002] The existing shield hobs and pipe jacking hobs are divided into alloy tooth hobs and non-insert hobs. The production of tooth hobs generally adopts interference fit between alloy teeth and tooth holes, and the interference is generally 0.04-0.06 mm, there is a certain difficulty in pressing alloy teeth. At present, press tooth pressing and hammer pressing are generally used. It is difficult to control the verticality of alloy teeth and holes when pressing in, and it is easy to cause alloy teeth and hammering due to pressure deviation. The method is more likely to cause cracking of the alloy teeth, and the existing gear pressing machine is not stable enough when it is used, and it is easy to shake from side to side, which has certain potential safety hazards

The invention relates to the technical field of tooth pressing machines, and discloses an inserted hob ring tooth pressing machine which comprises a bottom plate, a stand column is fixedly connected to the upper surface of the bottom plate, supporting assemblies are installed at the positions, close to the two sides of the stand column, of the upper surface of the bottom plate, and a limiting groove penetrates through the front surface of the stand column. A cutter ring fixing tool is slidably connected into the limiting groove, the cutter ring fixing tool is sleeved with a cutter ring, a sliding plate rail is fixedly connected to the upper surface of the stand column, a guide sleeve is installed on the lower surface of the sliding plate rail, and an oil cylinder sliding plate is slidably connected into the sliding plate rail. According to the inserted hob ring tooth pressing machine, the stability of the inserted hob ring tooth pressing machine in the working process can be improved through the supporting assemblies, the left-right shaking phenomenon of the tooth pressing machine is prevented, potential safety hazards are reduced, the tooth pressing machine can be stored after being used, surrounding space cannot be occupied, and the tooth pressing machine is easy to manufacture and low in cost. Operation is simple, and maintenance is easy. The tooth pressing machine is convenient to use and can be suitable for inserted cutter rings of various sizes.
Description
technical field [0001] The invention relates to the technical field of gear pressing machines, in particular to a gear pressing machine for insert hob cutter rings. Background technique [0002] The existing shield hobs and pipe jacking hobs are divided into alloy tooth hobs and non-insert hobs. The production of insert tooth hobs generally adopts interference fit between alloy teeth and tooth holes, and the interference is generally 0.04-0.06 mm, the alloy teeth are difficult to press in. At present, press teeth and hammering are generally used. It is difficult to control the verticality of the alloy teeth and the hole when the press is pressed, and it is easy to cause alloy teeth and hammering. The method is more likely to cause cracking of the alloy teeth, and the existing gear pressing machine is not stable enough, and it is easy to shake from side to side, and there is a certain potential safety hazard. Therefore, those skilled in the art provide a gear pressing machin...
