Abstract
The utility model relates to a fluid pressure type sleeve remove device mainly includes buckle, pull rod, main part frame, jack and hydraulic pump, its characterized in that: the cylindrical shape structure is made to the buckle, and threaded hole is bored to the lower part, and the buckle claw is greater than telescopic internal diameter, the pull rod both ends are all threaded, and the upper end links to each other with the buckle, and the lower extreme is connected with the main part frame, the main part frame is used for fixing three miniature jack. During the use filling in the buckle and getting a section of thick bamboo, make the buckle claw left -hand thread at the sleeve edge, the jack ejector pin withstands the milling machine head, the manually operation hydraulic pump, and jack ejector pin upward movement, the downstream of whole main part frame then can drive the buckle and pull out the sleeve. The present invention has simple structure and convenient operation.
Description
Technical field
The utility model is the instrument that the stirring-head sleeve in agitating friction welding takes out, and is specifically related to a kind of fluid pressure type sleeve withdrawing device.
Background technology
In engineer applied, milling head can be connected by sleeve with milling machine.Milling head and sleeve, the tightening state being reached the best between sleeve and the main shaft of milling machine by certain coordinating, just not easily being produced vibration when carrying out heavy cut like this, enhancing steadiness.The same friction stir welding machine converted by milling machine also uses sleeve, while being convenient for changing stirring-head, also makes welding comparatively steady.
But in actual production, due to the mismachining tolerance of stirring-head grip shank, usually make stirring-head coordinate with sleeve too tight, stirring-head can produce a large amount of heats, sleeve expanded by heating in welding process, and after making welding, sleeve is difficult to take out from milling machine head simultaneously.For this problem, we are ticked with the reinforcing bar that band hooks usually, and sometimes sleeve coordinates too tight with main shaft, and its hook also cannot go out by hook, extremely loses time and manpower.Sometimes be only the time that taking-up sleeve will waste several hours.
Summary of the invention
In order to overcome above problem, now provide a kind of fluid pressure type sleeve withdrawing device, be mainly and stir weldering middle sleeve taking-up instrument, this instrument, for the sleeve being difficult to take out, can save a lot of time.
The technical solution adopted in the utility model is: a kind of fluid pressure type sleeve withdrawing device, mainly comprise buckle, pull bar, main frame, jack and hydraulic pump, it is characterized in that: buckle makes cylinder barrel shaped structure, top is buckle pawl, bottom is drilled with screwed hole, and described buckle pawl is greater than the internal diameter of sleeve; There is screw thread at pull bar two ends, and upper end is connected with buckle, and lower end is connected with main frame; Main frame is fixed wtih three Minitype jacks, jack is connected with hydraulic pump.
Buckle described in the utility model is made up of spring steel, and buckle and pull bar change different size according to the size of sleeve, and be buckled in after entering sleeve inner, buckle pawl can return to the original form, and meet repeatedly use indeformable.
Principle of the present utility model is such: first filled in by buckle in the sleeve of needs taking-up.Because buckle has elasticity, buckle pawl can shrink when entering sleeve and enter, and after entering completely, buckle pawl tips upside down on sleeve.At this time, the push rod of jack withstands milling machine head, primer fluid press pump, and mandril of lifting jack upwards pushes up, and drive main frame to pull down together with pull bar, pull bar is ined succession buckle, will be drawn out together with sleeve simultaneously.
The beneficial effects of the utility model are: for the sleeve being difficult to take out, can save a lot of time.Simultaneously buckle and pull bar can be changed at any time, not only may be used for the taking-up of friction stir welding machine stirring-head sleeve, and the sleeve that also can be used for milling machine milling head takes out, can usage range wide.Hydraulic pressure pulling off device is simple to operate, very laborsaving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is operating diagram of the present utility model.
In the drawings, 1 is buckle, and 2 is pull bar, and 3 is main frame, and 4 is jack, and 5 is hydraulic pump; 6 is milling machine head; 7 is sleeve.
Detailed description of the invention
Detailed description of the invention of the present utility model is further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model is achieved like this, a kind of fluid pressure type sleeve takes out instrument, mainly comprise buckle 1, pull bar 2, main frame 3, jack 4 and hydraulic pump 5, it is characterized in that: buckle 1 makes cylindrical structural, and bottom is drilled with screwed hole, buckle pawl is greater than the internal diameter of sleeve; There is screw thread at pull bar 2 two ends, and upper end is connected with buckle 1, and lower end is connected with main frame 3; Main frame is uniformly distributed three Minitype jacks 4.As shown in Figure 2, during use, buckle is filled in the sleeve 7 that will get, because buckle is made up of spring steel, when entering, buckle shrinks and enters, and enters rear reinstatement completely, buckle pawl left-hand thread is in sleeve edges, now buckle pawl outer most edge should be less than the external diameter of sleeve, and mandril of lifting jack withstands milling machine head 6, manual operation hydraulic pump 5 simultaneously, mandril of lifting jack moves upward, then buckle can be driven to be pulled out by sleeve.
The above is only a specific embodiment of the present utility model, the protection domain be not intended to limit the present invention, all do with principle according to the present invention's spirit any amendment, be equal to and replace, to improve etc. the row all belonging to protection scope of the present invention.
Claims (2)
