Description

Machining tool for cutting hydraulic cylinder accessories Technical Field The application relates to the technical field of equipment machining, in particular to a machining tool for cutting hydraulic cylinder accessories. Background In the field of machining and manufacturing of hydraulic cylinder accessories, cutting machining is one of key procedures, and machining precision and efficiency of the cutting machining are directly influenced on quality and subsequent use performance of the accessories. However, the existing hydraulic cylinder accessory cutting tool has a plurality of problems in practical application, and the improvement of the processing quality and the production efficiency is restricted. The traditional cutting tool has poor universality, and hydraulic cylinder accessories with different sizes and shapes are required to be frequently replaced or subjected to complex adjustment. For example, for cylindrical fittings with different lengths and diameters, the original fixture is difficult to adapt through simple adjustment, so that the time consumption of clamping is increased, and the production cost is increased. Meanwhile, the clamping mode of the traditional tool is mostly limited in a single direction, if only the outer wall or the bottom of the workpiece is fixed, in the cutting process, the workpiece is easy to displace or shake due to cutting force and vibration, the cutting precision is affected, and even the rejection rate is increased, the clamping efficiency is low, and the requirement of mass production is difficult to meet. Disclosure of utility model The utility model aims to provide a processing tool for cutting hydraulic cylinder accessories, which is used for solving the problems in the background technology. A processing frock for hydraulic cylinder accessory cutting includes: the device comprises a placing platform, a bearing assembly and a limiting assembly, wherein the bearing assembly is arranged on the placing platform, one end of the limiting assembly is arranged on the placing platform, and the other end of the limiting assembly extends to the position right above the bearing assembly; The bearing assembly comprises a placing rail and two bearing pieces used for placing workpieces, wherein the two bearing pieces can slide on the placing rail, and each bearing piece comprises two bearing plates which are obliquely arranged; The limiting assembly comprises an outer wall limiting part and an inner wall limiting part, the inner wall limiting part is arranged on the placing track, one end of the inner wall limiting part can extend into the workpiece, the outer wall limiting part comprises a driving cylinder, a limiting clamping plate and a pushing part, and one end of the pushing part is arranged at the output end of the driving cylinder, and the other end of the pushing part is fixedly connected with the limiting clamping plate. Through above-mentioned technical scheme, adopt place platform, bearing subassembly and spacing subassembly collaborative structure, realize the omnidirectional to the hydraulic cylinder accessory from bottom bearing to the spacing accuse in top, work piece gesture is stable when the guarantee cutting, and spacing division of worker of the interior outer wall of spacing subassembly is applyed from accessory inner wall, outer wall respectively, forms three-dimensional spacing system, lets the work piece also be difficult for the displacement under the cutting force effect. Further, the side of actuating cylinder is equipped with the mount that is used for supporting it, the vertical setting of actuating cylinder and actuating cylinder's output extends to outside the mount, the mount below is equipped with the push plate with actuating cylinder output fixed connection, the push piece includes the push rod that two intervals set up, all overlaps on every push rod and is equipped with fixed sleeve, be equipped with push spring in fixed sleeve and push plate fixed connection and the fixed sleeve, spacing cardboard bottom and two push rod fixed connection. Through above-mentioned technical scheme, the vibration of work piece transmission when the cutting can be absorbed to the spring that sets up, prevents that vibration reverse transmission from damaging the cylinder, and on the other hand, the elastic structure lets spacing cardboard more flexible to the centre gripping of work piece outer wall, adapts to the accessory of different outer wall roughness, has both guaranteed spacing power, avoids rigidity extrusion damage work piece surface again. Further, the inner wall locating part includes the fixed plate and holds a section of thick bamboo, hold a section of thick bamboo level setting and hold and be equipped with a plurality of conflict piece on the section of thick bamboo lateral wall, every all be equipped with on the conflict piece and extend to the connecting block that holds in the section of thick bamboo, every all be equipped with first w
