The two-way top of rod-pulling type
Technical field
This utility model relates to machining frock technical field, more specifically a kind of two-way top of rod-pulling type.
Background technology
Existing two-way ejection device is all level due to top ends, and the scope of application is very limited, and can only be supported on two parallel faces.When processing object is the parts having certain angle of inclination, top ends only has the least area and component contact to be processed, with the deformation or the damage of two-way ejection device that easily cause parts to be processed;When being machined with given shape parts, often cannot find force application location, and affect work efficiency.
Summary of the invention
For solving the problems referred to above, the deficiencies in the prior art, this utility model are overcome to provide a kind of simple in construction, easy to operate, it is possible to the two-way top of rod-pulling type for multi-angle, given shape parts.
For achieving the above object, the two-way top of rod-pulling type that this utility model provides, including turning handle, thread, movable sleeve, upper support handle, connecting plate, inserting groove, universal joint, lower support handle, fixed cover, anti-back pin, movable sleeve female thread, also include the top cap that can change, it is characterized in that: thread outer surface is provided with screw thread, one end of described thread is provided with turning handle, described thread is equipped with movable sleeve near one end of turning handle, and two flat edges of movable sleeve are connected by bolt and one upper support handle respectively;Thread is provided with, away from one end of turning handle, the fixed cover that can only rotate around thread centrage, the middle cylinder of described fixed cover is set on thread, two flat edges of fixed cover are respectively by supportting handle connection under bolt and one, thread is provided with through hole near the top of fixed cover, is inserted with anti-back pin in through hole;The upper support handle of homonymy is connected with connecting plate by bolt respectively with lower support handle, and described connecting plate is connected with the universal joint being provided with inserting groove also by bolt;Connection-peg on described inserting groove and top cap matches.
Further, it is provided with, in described movable sleeve middle cylinder, the female thread matched with thread outer surface thread.
Further, the inserting mode that described top cap and universal joint use connection-peg and inserting groove to coordinate connects, and top cap can be replaced according to the structure of workpiece to be processed.
The beneficial effects of the utility model are: this utility model simple in construction, easy to operate, the setting of universal joint, and it can be nonparallel for making workpiece to be processed work surface;Top cap and universal joint use the socket connection that connection-peg and inserting groove coordinate, the convenient shape according to workpiece to be processed to select the shape of top cap.

Detailed description of the invention:
Clearer for the purpose making this utility model implement, technical scheme and advantage, below in conjunction with accompanying drawing of the present utility model, this utility model is further described in more detail.
To in description of the present utility model; it will be appreciated that; indicating position or position relationship be described as based on orientation shown in the drawings or position relationship; it is for only for ease of description this utility model and simplifies description; rather than instruction or the hint device of indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that restriction to this utility model protection domain.
In attached Figure 16, the two-way top of rod-pulling type that this utility model provides, including turning handle 1, thread 2, movable sleeve 3, upper support handle 4, connecting plate 5, inserting groove 6, universal joint 7, lower support handle 8, fixed cover 9, anti-back pin 10, movable sleeve female thread 11, also include the top cap that can change, it is characterized in that: thread 2 outer surface is provided with screw thread, one end of described thread 2 is provided with turning handle 1, described thread 2 is equipped with movable sleeve 3 near one end of turning handle 1, it is provided with, in described movable sleeve 3 middle cylinder, the female thread matched with thread 2 outer surface thread;Two flat edges of movable sleeve 3 are connected by bolt and one upper support handle 4 respectively;Thread 2 is provided with, away from one end of turning handle 1, the fixed cover 9 that can only rotate around thread 2 centrage, and the middle cylinder of described fixed cover 9 is set on thread 2, and two flat edges of fixed cover 9 are connected by support handle 8 under bolt and respectively;Thread 2 is provided with through hole near the top of fixed cover 9, is inserted with anti-back pin 10 in through hole;The upper support handle 4 of homonymy is connected with connecting plate 5 by bolt respectively with lower support handle 8, and described connecting plate 5 is connected with the universal joint 7 being provided with inserting groove 6 also by bolt;Connection-peg on described inserting groove 6 and top cap matches, and the inserting mode that described top cap and universal joint 7 use connection-peg and inserting groove 6 to coordinate connects, and top cap can be replaced according to the structure of workpiece to be processed.
During application, the top cap matched according to member profile structure choice flat board top cap 12 to be processed, V-arrangement top cap 13 or other and member profile structure to be processed, connection-peg in top cap is inserted inserting groove 6, regulation universal joint 7 is fitted with both sides top cap to parts surface to be processed simultaneously, rotate turning handle 1, it is achieved two-way support.
