Description

Drilling part cleaning plant
Technical field
The invention belongs to part processing technique field more particularly to a kind of drilling part cleaning plants.
Background technique
In general, people often have after carrying out corresponding drilling processing to part using traditional mechanical equipment Many clasts remain in hole, before carrying out following process to drilling, need to clean out these clasts, subsequent to improve The efficiency and quality of processing.It is all manually to be cleared up manually part blind hole, but clear up manually in traditional method for cleaning Mode clears up slow speed, a large amount of labours of consuming and is difficult to clean out.
To solve the above-mentioned problems, the patent of Publication No. CN105619164A discloses in a kind of processing of drilling part uses Hole automatic cleaning apparatus, including workbench, first motor is fixedly installed on workbench, and first motor utilizes screw-driven connection There is after sleeve, after sleeve front end is equipped with front sleeve, and front sleeve is connected with hairbrush;Second motor is installed inside after sleeve, the Two motors are connected with main shaft, and main shaft is connected with front sleeve sliding, drive front sleeve rotation and movement.The device is using hairbrush blind It is rotated in and out in hole, the clast in blind hole is taken out of automatically, but part clast can be extruded in blind when entering blind hole by hairbrush in this way Hole bottom, makes to clear up difficulty and increases, while when hairbrush takes clast out of, not carrying out centralized collection to clast, being scattered in clast In working environment, it is easy the injury exposed skin of worker, is fallen into equipment, long-term accumulation may block equipment;Simultaneously Hairbrush size is fixed, and can not be cleared up the blind hole of different pore size size.
Summary of the invention
The purpose of the present invention is to provide a kind of drilling part cleaning plants, inside the blind hole to solve different pore size size The cleaning problem of clast, while centralized collection is carried out to the clast cleaned out.
In order to achieve the above object, base case of the invention are as follows: a kind of drilling part cleaning plant, including wash-up tray, Filing sucking machine structure and discharging mechanism is arranged inside in wash-up tray bottom opening;
The connection that the filing sucking machine structure includes the piston plate being slidably connected in wash-up tray, is fixedly connected with piston plate bottom The cleaning board that bar, the hollow pipe being fixedly connected with connecting rod bottom and hollow pipe outer wall are circumferentially arranged, be inside connecting rod it is hollow, Hollow tube base is equipped with the suction bits mouth being connected to connecting rod, and cleaning board is equipped with hairbrush layer far from the side of hollow pipe, and piston plate connects It is connected to and controls its power source moved up and down;
The discharging mechanism includes being built in the skewback of wash-up tray, the opening in connecting rod and set on wash-up tray side wall Crumb mouth, skewback is slidably connected with connecting rod, and skewback is tilted towards the side for being equipped with crumb mouth, and skewback side is provided with through-hole, Through-hole is located between connecting rod outer wall and cleaning chamber interior wall, and interior sealing slidably connects two pieces of fixed blocks, fixes between fixed block It is connected with compressed spring, the side wall of wash-up tray and connecting rod is respectively equipped with the groove that can be engaged with fixed block, is full of liquid in through-hole Body.
The working principle and beneficial effect of this base case are: the space between wash-up tray inner piston plate and skewback is close Space is closed, the groove of fixed block and wash-up tray in skewback is fixed, when piston plate is controlled by power source and is moved down, The confined space is positive pressure, and when moving up, become negative pressure in space;In addition, connecting rod is equipped with opening, and and hollow pipe Connection, hollow pipe is equipped with suction bits mouth again, then when positive pressure, the air draft into connecting rod, and then clast is blown, keep it not viscous with blind pore wall Even, when negative pressure, by connecting rod air-breathing, clast self-priming bits mouth is entered in wash-up tray, then falls on skewback.
The hairbrush layer of cleaning board can be prevented when connecting rod is blown in blind hole, and clast flies out blind hole, while cleaning blind The clast of hole side wall attachment, makes clast fall into blind via bottom, convenient for drawing;Close to the fixed block of wash-up tray side and clear in skewback Manage the engaging of case upper groove, fixed position seals wash-up tray, make clast will not self-cleaning bottom portion leak out, and when in connecting rod Shifting keeps groove thereon opposite with cavity, the compressed spring effect of the fixed block close to connecting rod side, into connecting rod Groove, makes hydraulic unbalance in cavity, drives and is retracted into cavity close to the fixed block of wash-up tray, at this time skewback and connecting rod is fixed connects It connects, connecting rod drives skewback to move up, and until skewback inclined upward face and crumb mouth are mutually neat, clast is concentrated from crumb mouth and is discharged.
Further, cleaning board includes several fanning strips, and fanning strip is divided into rotor plate and fixed plate along its centre of surface line, Gu Fixed board is provided with cavity close to rotor plate side, and rotor plate is slidably connected with cavity, is fixedly connected between rotor plate and cavity bottom There is first back-moving spring, second back-moving spring is fixedly connected between fixed plate and connecting rod.
Such structure protrude into cleaning board can in the blind hole of different pore size to be cleaned, when into small-bore blind hole, Fixed plate, which is squeezed, compresses second back-moving spring, bounces back into hollow pipe, while fixed plate retraction can apply pressure to rotor plate, First back-moving spring is compressed, rotor plate bounces back into cavity, reduces the area of entire cleaning board, can smoothly enter into cleaning board blind Hole, while when cleaning board leaves blind hole, first back-moving spring and second back-moving spring can also make to clean sheet reset.
Further, fixed plate is provided with blowing mouth close to hairbrush layer side, and blowing mouth side wall is downward and inclined oblique inwardly Face, and tracheae is communicated between blowing mouth and connecting rod, the junction of tracheae and connecting rod is equipped with check valve.
When pushing piston plate in this way, the gas in connecting rod first flows into blowing mouth, and the clast of surrounding in blind hole is blown to centre It is dynamic, while when piston plate moves up, check valve makes blowing mouth not generate suction to clast, prevents clast from entering tracheae, by gas Blockage.
Further, workbench is equipped with below wash-up tray, workbench is equipped with several limiting slots.It in this way can be same to different parts Shi Dingwei clear up wash-up tray can disposably to multiple parts, not have to repeatedly starting and stopping device, saves the time.
Further, the bottom of crumb mouth can utilize the gravitional force of clast in this way, be convenient for clast downwards and towards outer incline Discharge.
Further, wash-up tray is externally provided with collecting box, and collecting box is connected to crumb mouth, centralized collection clast, is convenient for subsequent place Reason.
