Description
Technical field
This utility model relates to a kind of long inner bore machining device, especially relates to a kind of processing device with many places step, is applied in helicoid hydraulic motor process of manufacture, mainly realizes the function of housing class endoporus machine-shaping.Belong to petroleum machinery equipment manufacturing technology field.
Background technology
General helicoid hydraulic motor is divided into five big assemblies: by-pass valve assembly, anti-lost assembly, motor assembly, universal drive shaft assembly and driving-shaft assembly.Containing transmission shaft shell, TC bearing, string bearing, power transmission shaft in driving-shaft assembly, during for ensureing to assemble, the axiality of 4 parts, need to strictly control the axiality of transmission shaft shell endoporus.Owing to propeller shaft length is longer, and have many places step, current boring bar cannot utilize clamped one time operation to complete interior hole machined, and the size and dimension of boring bar is subjected to certain restriction, the rigidity causing cutter is relatively low, especially when cutting, it is easy to cause cutting vibration in the case of rigidity is relatively low, more it cannot be guaranteed that inner hole precision.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of scalable long endoporus step processing unit (plant) for above-mentioned prior art, and it is simple to operate, it is possible to product quality is effectively ensured.
The technical scheme in the invention for solving the above technical problem is: a kind of scalable long endoporus step processing unit (plant), it includes cutter bridge, described cutter bridge center offer one in elongated hole, described interior elongated hole front end is provided with a circle square hole, it is provided with wiper block in described square hole, described cutter bridge rear end is provided with fixing nut, it is coated with push rod in described interior elongated hole, described push rod includes sinciput apical segment and thread segment, described thread segment rear end is stretched out outside fixing nut, being provided with locking nut on described thread segment, described locking nut is positioned on rear side of fixing nut.
Described wiper block includes skewback, and described skewback is fixedly installed wear-resistant block by screw.
Match with the inclined-plane of skewback in described top section of front end.
Described cutter bridge front end is fixedly installed cutter by lock-screw.
Compared with prior art, the utility model has the advantage of:
This utility model one scalable long endoporus step processing unit (plant), it is simple to operate, substantially improves the axiality of hole machined in the length of step, product quality has been effectively ensured.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As shown in Fig. 1 ~ Fig. 3, a kind of scalable long endoporus step processing unit (plant) in the present embodiment, it includes cutter bridge 3, described cutter bridge 3 center offer one in elongated hole 3.1, described interior elongated hole 3.1 front end is provided with a circle square hole 3.2, it is provided with wiper block 2 in described square hole 3.2, described cutter bridge 3 rear end is provided with fixing nut 5, it is coated with push rod 4 in described interior elongated hole 3.1, described push rod 4 includes sinciput apical segment 4.1 and thread segment 4.2, described thread segment 4.2 rear end is stretched out outside fixing nut 5, it is provided with locking nut 6 on described thread segment 4.2, described locking nut 6 is positioned on rear side of fixing nut 5.
Described wiper block 2 includes skewback 2.1, and described skewback 2.1 is fixedly installed wear-resistant block 2.3 by screw 2.2.
Match with the inclined-plane 2.4 of skewback 2.1 in described top section of 4.1 front ends.
Described cutter bridge 3 front end is fixedly installed cutter by lock-screw 1.
Add man-hour, wiper block 2 is put into cutter bridge 3, adjust position of tool tip and determine allowance, cutter bridge 3 is put into inner hole of workpiece, pulls push rod 4 with spanner, make wiper block be close to work piece inner surface, now can be processed, this just makes the long coaxiality of inner hole being machined with step be substantially improved.
In addition to the implementation, this utility model also includes the technical scheme that other embodiments, all employing equivalents or equivalence substitute mode are formed, within all should falling into this utility model scope of the claims.
