Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to the telescopic clamping device of a kind of pressing plate.
Background technology
In machine tooling, conventionally after need to using clamping device that workpiece is fixing, carry out again follow-up processing, so clamping device is widely used in workpiece manufacture field, and existing clamping device shortcoming is: the pressing plate of holding workpiece can only be made holding action, and pressing plate holding action is less, therefore the gap of pressing plate clamping head and workpiece to be clamped is less, so that the clip position of appointment is put into or taken out to workpiece is just more time-consuming.
Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of pressing plate telescopic clamping device, and the pressing plate of this clamping device is scalable, thus put into and to take out workpiece easier, thus the efficiency clamping can be improved.
For achieving the above object, the technical solution of the utility model is: the telescopic clamping device of pressing plate, comprise pedestal, cam, fulcrum post, the bolt that pressing plate with clamping head is fixedly connected with pedestal with lower end, described pressing plate middle part is provided with the strip hole that described bolt inserts, sheathed Compress Spring on bolt between described pressing plate and pedestal, bolt upper end and cam are hinged, described fulcrum post is positioned on the pedestal of clamping head far away one end, wherein, described cam is provided with cam pin, described pressing plate is provided with the backing pin that described cam pin promotes, pressing plate clamping head far away one end is provided with blind hole, described pressing plate clamping head far away one end is provided with resetting-mechanism, and described resetting-mechanism comprises bearing, and release link is connected with bearing with release link described in back-moving spring, and in described insertion blind hole, described back-moving spring is sheathed in release link.
While adopting technique scheme, when the nearly heart side that cam radius is less goes to pressing plate upper surface, pressing plate is spring thrust upwards by compression, workpiece is unclamped, now, cam pin on cam is towards the pressing plate backing pin clamping on first thruster dynamic pressure plate far away, and pressing plate is retracted towards the first side of clamping far away, can go out workpiece by fast fetching; Put after workpiece, eccentric side larger cam radius is gone in pressing plate upper surface process, back-moving spring in release link is towards clamping first thruster dynamic pressure plate, pressing plate clamping head extend out to workpiece to be clamped top, cam is executed at pressing plate upper surface and is applied downward component simultaneously, the supported pin in pressing plate clamping head far away one end supports, so pressing plate clamping head one end bottom by piece-holder.The utility model utilizes cam pin and backing pin to promote pressing plate and retracts, and utilizes bearing, release link and back-moving spring to promote pressing plate and stretches out, and the pressing plate of clamping device is scalable, thus put into and to take out workpiece easier, thus can improve the efficiency clamping.
Further, cam is provided with handle, and cam handle one side far away is nearly heart side, and handle is vertically upward time, cam is in unclamping pressing plate state, and when handle goes to level, cam is in clamping platen state, from vertically pulling handle to level, the gravity of handle can be used as the power applying, so more laborsaving.
Further, the first side of described pressing plate clamping far away is provided with the chute coordinating with fulcrum post, and in pressing plate telescopic process, fulcrum post slides in chute, can limit the skew of pressing plate vertical telescopic direction, pressing plate is moved more stable.
Further, between the upper surface of described cam and pressing plate, be provided with spheric washer, the friction of cam rotation process is larger, and spheric washer can avoid cam directly to contact with pressing plate, thus not only can reduce the wearing and tearing of pressing plate, and it is convenient to change spheric washer.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the telescopic clamping device embodiment of the utility model pressing plate.
The specific embodiment
As shown in Figure 1, the telescopic clamping device of a kind of pressing plate, comprise pedestal 1, cam 5, fulcrum post 8, the bolt 3 that pressing plate 2 with clamping head is fixedly connected with pedestal 1 with lower end, described pressing plate 2 middle parts are provided with the strip hole that described bolt 3 inserts, sheathed Compress Spring 4 on bolt 3 between described pressing plate 2 and pedestal 1, bolt 3 upper ends and cam 5 are hinged, described fulcrum post 8 is positioned on the pedestal 1 of clamping head far away one end, wherein, described cam 5 is provided with cam pin 6, described pressing plate 2 is provided with the backing pin 7 that described cam pin 6 promotes, pressing plate 2 clamping head far away one end are provided with blind hole, described pressing plate 2 clamping head far away one end are provided with resetting-mechanism, and described resetting-mechanism comprises bearing 11, and release link 10 is connected with bearing 11 with release link 10 described in back-moving spring 9, and in described insertion blind hole, described back-moving spring 9 is sheathed in release link 10.In the present embodiment, cam 5 is provided with handle, and cam 5 handle one side far away is nearly heart side; The first side of described pressing plate 2 clamping far away is provided with the chute coordinating with fulcrum post 8; Between the upper surface of described cam 5 and pressing plate 2, be provided with spheric washer.
Concrete using method:
As shown in Figure 1, be illustrated as pressing plate 2 and unclamp workpiece 12 states.Workpiece to be clamped 12 is positioned on pedestal 1, pull handle downwards, the larger eccentric side of cam 5 radiuses goes to pressing plate 2 upper surfaces, the back-moving spring 9 that is arranged in blind hole in release link 10 promotes pressing plate 2 left, pressing plate 2 clamping heads extend out to workpiece to be clamped 12 tops left, simultaneously cam 5 is executed at pressing plate 2 upper surfaces and is applied downward component, and the pressing plate 2 supported pins 8 in clamping head far away one end support, so pressing plate 2 clamping head one end bottoms workpiece 12 is clamped; Upwards pull handle, the nearly heart side that cam 5 radiuses are less goes to pressing plate 2 upper surfaces, and pressing plate 2 is spring 4 thrust upwards by compression, workpiece 12 is unclamped, and now, the cam pin 6 on cam 5 promotes the backing pin 7 on pressing plate 2 to the right, pressing plate 2 is retracted to the right, can go out workpiece 12 by fast fetching.
