Description

A kind of tiny hollow pipe deep hole of workpiece cools down abrasive machining device automatically

Technical field

The utility model relates to hard brittle material deep processing equipment fields, more particularly, to a kind of tiny hollow pipe deep hole of workpiece Automatic cooling abrasive machining device.

Background technique

It is well known, full-automatic grinding process equipment, automatic grinding part, because its relevant item is few and movement is simple, according to Appliance circuit System design technology level is easier to realize at present, but very multiple for automatic loading/unloading and automatic card-loading material It is miscellaneous, for different workpieces, by the way of or letter or numerous；A kind of mode is to utilize magnetism, such as the inner hole grinding machine of bearing lantern ring The structure that is loaded, be exactly by magnetic patch be mounted in bistrique opposite certain position, the center of magnetic patch and the center of bistrique are consistent, under magnetic patch Side and vertically and magnetic patch, such as electromagnetism or permanent magnetism, fills a small supporting plate, and the size of supporting plate is that processed bearing lantern ring size determines, The orderly discharge of processed bearing lantern ring is placed in the device between magnet ring and bistrique, when bearing lantern ring enters the device Corresponding position is just sucked by the magnetic force of magnetic patch, and then bistrique can be to tools for inner bores of workpieces, and operator takes out after grinding Workpiece is packed into next workpiece, which is sucked by magnetic force is ground, reciprocation cycle；It is this be loaded mode mainly due to Limited by magnetic force size, it is often all very thin to be sucked ground workpiece, thickness between 3~5 millimeters, so using it is magnetic for Tiny and long round tube part can not axial restraint；

Another way adds a gravity pinch roller card pressure workpiece using two support rollers；The structure that is loaded is that have small one and large one Two support rollers and a pinch roller composition corresponding with big supporting wheel, three wheels are mutually 120 degree, have motor to drive and rotate synchronously, on The pinch roller in face can move up and down certain distance, allow workpiece to be machined to pass in and out in order that opening；Processed workpiece is placed on three In the square box of a funnel shaped above a wheel left side or the right；It is open above square box, workpiece is conveniently put, here is One and the close discharge port of workpiece to be machined size, discharge port are directed at three wheel subcenters；When filling workpiece, pinch roller is lifted upwards Rise, workpiece is pushed between two following support rollers, workpiece in place after, pinch wheel descending is simultaneously using the gravity of device on pinch roller to work Part pressurizes while workpiece being driven to rotate；Then bistrique can carry out inner hole grinding to workpiece；Grinding terminates, and pinch roller opens, operation Member take out workpiece, next workpiece by self gravity enter, pinch wheel descending, into it is next back and forth；The patent structure is excessively multiple It is miscellaneous, although capableing of the workpiece of the tiny big L/D ratio of clamping, this structure in the feeding process, since workpiece is long and thin small, It is easy to shake when discharging, so as to cause the fluency that not can guarantee self-emptying；

It can be seen that existing full-automatic grinding process equipment is in structure and use, it is clear that there are still have it is inconvenient with it is scarce It falls into, and needs to be further improved；Therefore it is deep how to found a kind of new structural tiny hollow tube workpiece of big L/D ratio Hole full-automatic grinding process equipment, also becoming current industry pole needs improved target；

It is complete certainly that Chinese patent (notification number CN203993400U) discloses a kind of tiny big L/D ratio hollow pipe deep hole of workpiece Dynamic grinding equipment；The place though patent makes progress compared with traditional equipment, patent structure is complicated, assembly precision require compared with Height, the frequent Caton of automatic loading/unloading, elastic collet cannot be rotated synchronously with main shaft in actual use, need operator frequent Maintenance, it is time-consuming and laborious.
