Abstract
The invention discloses a quick clamping device of a cam, comprising a base [1], a fixed block [10], a pressure lever [3] and a cam device, wherein the fixed block [10] is fixed on the base [1]; the pressure lever [3] is hinged at one end of the fixed block [10] to from a left end and a right end; the cam device is connected with the other end of the fixed block [10] and comprises a pressure shaft [5], a rotating shaft [9] and a handle [7]; the pressure shaft [5] is provided with an eccentric hole the diameter of which is matched with that of the rotating shaft [9]; the rotating shaft [9] is sleeved and fixed in the eccentric hole; two ends of the rotating shaft [9] are movably connected with the fixed block [10]; and the handle [7] is fixedly connected with the pressure shaft [5]. The invention can realize the quick clamping of the workpieces at high clamping efficiency.
Description
Technical field
The present invention relates to a kind of clamping device, especially a kind of device of realizing quick clamping with cam.
Background technology
On the machining, clamping device is a kind of important processing aid.Workpiece is fixing on clamping device, just can carry out turnning and milling and cut processing.The clamping device commonly used such as rotating disk, the fraise jig of lathe all are to realize clamping by nut and connecting of bolt.The shortcoming of above-mentioned clamping device is: clamping and unclamping needs the more time of cost to carry out clamp nut or unclamp nut, and operating efficiency is lower.
Summary of the invention
Purpose of the present invention is exactly to solve clamping device inefficiency and problem commonly used, and a kind of device that utilizes cam to realize and clamping fast is provided.
The present invention adopts technical scheme to be: a kind of cam fast fixture, it is characterized in that it comprises base, is fixed on fixed block on the base, is hinged on the cam gear that fixed block one end forms the depression bar at two ends, the left and right sides and is connected in the fixed block other end, described cam gear comprises last item, rotating shaft and handle, last item is provided with diameter and the adaptive eccentric orfice of rotating shaft diameter, shaft set also is fixed in the eccentric orfice, the two ends of rotating shaft are actively connected on the fixed block, and handle and last item are affixed.
For making things convenient for the roof pressure of last item and depression bar, the right-hand member of described depression bar and last item contact site are connected with bolt.Can make squeezing effect more obvious by the contacting of bolt end and last item like this.
Adopt technique scheme, when need when carrying out clamping work pieces, workpiece is placed the below of base one side pressure bar one end, do the turning handle of will exerting oneself, handle will drive last item and rotate, rotate with rotating shaft because last item is an off-centre, therefore, last item is with the other end of pressure ram, depression bar is risen, the other end of depression bar descends and pushes workpiece, workpiece is fixed, thereby reached the purpose of clamping.
In sum, the invention has the beneficial effects as follows: because the present invention can realize quick clamping by cam mechanism, so the present invention clamp convenient and swift, the efficient height.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
Among the figure, 1, base, 2, workpiece, 3, depression bar, 4, pivot pin, 5, last item, 6, bolt, 7, handle, 8, key, 9, rotating shaft, 10, fixed block.
The specific embodiment
Cam fast fixture of the present invention as shown in Figure 1, comprises base 1, is fixed on fixed block 10 on the base 1, is hinged on the cam gear that fixed block 10 1 ends form the depression bar 3 at two ends, the left and right sides and are connected in fixed block 10 other ends.Depression bar 3 is realized with fixed block 10 hinged by pivot pin 4.
Cam gear comprises last item 5, rotating shaft 9 and handle 7, and last item 5 is provided with diameter and the adaptive eccentric orfice of rotating shaft 9 diameters, and rotating shaft 9 suits also are fixed in the eccentric orfice, and present embodiment rotating shaft 9 realizes with last item 5 fixing by key 8.The two ends of rotating shaft 9 are actively connected on the fixed block 10, and handle 7 is affixed with last item 5.The right-hand member of described depression bar 3 and last item contact site are connected with bolt 6.
Claims (2)
1. cam fast fixture, it is characterized in that it comprises base [1], is fixed on fixed block [10] on the base [1], is hinged on the cam gear that fixed block [10] one ends form the depression bar [3] at two ends, the left and right sides and are connected in fixed block [10] other end, described cam gear comprises last item [5], rotating shaft [9] and handle [7], last item [5] is provided with diameter and the adaptive eccentric orfice of rotating shaft [9] diameter, rotating shaft [9] suit also is fixed in the eccentric orfice, the two ends of rotating shaft [9] are actively connected on the fixed block [10], and handle [7] is affixed with last item [5].
