Abstract
The utility model discloses a guiding clamping device. The problems that according to an existing clamping device, the surface of a workpiece is prone to damage and clamping is unstable are solved. The clamping device comprises a guide rod. A strip-shaped guide groove is formed in the guide rod in the length direction of the guide rod. A pressing block is arranged in the side direction of the guide rod. A clamping table is arranged below the pressing block. A guide pin is arranged in the middle of the pressing block. The guide pin is placed in the guide groove and can slide along the guide groove. The two ends of the upper portion of the pressing block are respectively hinged to a first drive rod. The ends of the two first drive rods are respectively hinged to a second drive rod. The ends of the two second drive rods are respectively hinged to the top end of the guide rod. The hinged points of the two first drive rods and the second drive rods are respectively provided with a push block. The overall length of each first drive rod and the corresponding second drive rod is larger than the distance from the hinged point at the top ends of the second drive rods to the bottom of the guide groove. When the clamping device is used for clamping the workpiece, the workpiece is not prone to damage and clamping is stable.
Description
Technical field
The utility model relates to the fixture for machine tooling, is specifically related to a kind of guiding clamping device.
Background technology
clamping device is widely used in the processing of machine tool element, at present, in the production and processing of small batch workpiece, General Requirements clamping device convenient operation simple in structure, therefore existing clamping device generally adopts cylinder or oil cylinder direct tape splicing dynamic pressure plate clamping work pieces, often there is following problem in the clamping device of this structure: 1. without indirect transmission mechanism, and adopt piston rod to be directly with dynamic pressure plate holding workpiece, in clamping moment, tend to that workpiece is impacted to dynamics larger, the workpiece that has specific (special) requirements for surface flatness etc., can cause damage; 2. fluctuation of service in holding workpiece process, easily produces small rocking, and affects positioning precision.
Utility model content
The utility model provides a kind of guiding clamping device, to solve the easy damaged surface of the work that existing clamping device exists, the problem of clamping fluctuation of service.
Guiding clamping device, comprise guide rod, on guide rod, have the strip guide groove along guide rod length direction, the side direction of guide rod is provided with briquetting, the below of briquetting is provided with grain-clamping table, briquetting middle part is provided with pilot pin, pilot pin is placed in guide groove and can slides along guide groove, briquetting both upper ends thereof is hinged with respectively the first drive rod, the end of two first drive rods is hinged the second drive rod all, the end of two second drive rods is all hinged on the top of guide rod, the pin joint place of two first drive rods and the second drive rod is equipped with pushing block, the total length of the first drive rod and the second drive rod is greater than the second drive rod top hinge to the distance of guide groove bottom.
The beneficial effects of the utility model: two pushing blocks inwardly promote in opposite directions, and the first drive rod and the second drive rod are opened gradually, under the driving of the first drive rod, pressing plate will move until workpiece pressing downwards gradually.Because first this clamping device forces in two drive rods by pushing block; then via the drive rod that is symmetricly set on briquetting both sides, drive briquetting motion gradually downwards; therefore; during clamping, can reduce the impact to workpiece, protection workpiece, simultaneously; in the guide groove of pilot pin on briquetting on guide rod, slide; play the effect of guiding, briquetting can be offset, motion stabilization and accurate positioning.
Further, between the second drive rod top hinge and pilot pin, be provided with extension spring.In the time of need to unclamping workpiece, remove the power that two pushing blocks are bestowed two drive rods, like this, under the effect of extension spring restoring force, briquetting automatically resets and unclamps workpiece.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model guiding clamping device embodiment.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Guiding clamping device as shown in Figure 1, comprise guide rod 1, on guide rod 1, have the strip guide groove 11 along guide rod length direction, the side direction of guide rod 1 is provided with briquetting 2, the below of briquetting 2 is provided with grain-clamping table 3, briquetting 2 middle parts are provided with pilot pin 21, pilot pin 21 is placed in guide groove 11 and can slides along guide groove 11, briquetting 2 both upper ends thereof are hinged with respectively the first drive rod 4, the end of two first drive rods is hinged the second drive rod 5 all, the end of two second drive rods is all hinged on the top of guide rod 1, the pin joint place of two first drive rods and the second drive rod is equipped with pushing block 6, pushing block 6 is connected with cylinder piston rod, the total length of the first drive rod 4 and the second drive rod 5 is greater than the second drive rod 5 top hinges to the distance of guide groove 11 bottoms, between the second drive rod 5 top hinges and pilot pin 21, be provided with extension spring 7.
