Abstract
The invention discloses a cam compression clamp and aims to solve the problem that a boss horizontally extending out on a workpiece cannot be well fixed in the prior art. According to the scheme disclosed by the invention, the cam compression clamp comprises an engine bed, a fixed supporting part, a clamping jaw, a cam and a guide rod, wherein the fixed supporting part is used for lifting up the workpiece; the clamping jaw is used for compressing the upper surface of the workpiece; the cam is located below the clamping jaw and serves as a force application device; the guide rod is connected onto the clamp body; the clamping jaw has a freedom of vertical motion under the restraint of the guide rod; a reset spring is also arranged between the clamping jaw and the guide rod; the clamping jaw comprises an upper driven end and a lower driving end, wherein the upper driven end plays a clamping role, and the lower driving end plays a force application role. The cam compression clamp is characterized in that the cam is abutted with the lower driving end, and the geometric center of a clamping part of the upper driven end and the geometric center of the part, contacted with the cam, of the lower driving end are located on the same plumb line. The technical scheme disclosed by the invention has the characteristic that the boss horizontally extending out on the workpiece can be well fixed.
Description
Technical field
The present invention relates to a kind of anchor clamps.
Background technology
Jig is important process equipment indispensable in the machinery manufacturing industry, can guarantee mechanical processing quality, enhances productivity, reduces production costs, reduce labor intensity.
In the process of reality, the shape and structure of workpiece is ever-changing, for heteroid workpiece designs corresponding with it anchor clamps, is mechanical field staff's long-range mission.And the clamping of horizontal ledge on the workpiece is exactly one.
Summary of the invention
The invention is intended to provide a kind of cam pressing anchor clamps, to solve the fixation problem of the boss that level is stretched out on the workpiece in the prior art.
Cam pressing anchor clamps in this programme, comprise support, be used for to hold up workpiece fixed support portion, be used for the workpiece pressing upper surface jaw, be positioned at the jaw below and as the cam of force application apparatus; Be connected to the guide post on the clamp body; Described jaw has upper and lower freedom of motion under described guide post constraint; Also be provided with back-moving spring between described jaw and the described guide post; Described jaw has comprised the top driven end of clamping action and has played the bottom drive end of application of force effect, it is characterized in that cam and bottom drive end offset; The geometric center at the clamping position of top driven end is positioned at same plumb line with the geometric center at the position that the bottom drive end contacts with cam.
The characteristics of technique scheme are: can well finish the boss that level on the workpiece is stretched out and be fixed.
Further, a side at workpiece place is provided with the Level tune piece on the fixed support portion, and the Level tune piece is connected with fixed support portion by bolt, and the jaw drive end is provided with the vertical adjusting bolt, and the edge offsets under the afterbody of vertical adjusting bolt and the cam.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the schematic diagram of the embodiment of the invention.
The specific embodiment
As shown in Figure 1: the cam pressing anchor clamps in this enforcement comprise fixed support portion 1 and activity compressed part 2, the supporting surface 11 of fixed support portion 1 cooperates with the lower surface of workpiece convex platform, activity compressed part 2 is the C font of hollow, fixed support portion 1 is provided with guide post, activity compressed part 2 is slidingly socketed with guide post, also is provided with the Compress Spring 12 that is connected with guide post in the activity compressed part 2.
The upper end 21 of the C font of activity compressed part 2 cooperates with workpiece boss upper surface, be provided with rotating cam 3 under the supporting surface 11 of fixed support portion 1, the termination of the C font below of activity compressed part 2 is vertical adjusting bolt 22, vertical adjusting bolt 22 is connected with activity compressed part 2 by screw thread, the afterbody of vertical adjusting bolt 22 and cam 3 offset, and are used for the vertical height of adjusting activity compressed part 2.
Fixed support portion 1 is provided with Level tune piece 4 in a side at workpiece place, and Level tune piece 4 is connected with fixed support portion 1 by bolt, is used for regulating the horizontal level of workpiece.
The using method of above-mentioned anchor clamps is: first rotating cam, the one side that radius is less on the cam is contacted with vertical adjusting bolt 22, this moment, upper end 21 was in a higher position under the effect of Compress Spring 12, can put into the horizontal ledge on the workpiece between the supporting surface 11 of upper end 21 and fixed support portion 1 this moment, the right side of workpiece pushes against Level tune piece 4, the workpiece rear rotating cam 3 that puts in place, the change in radius of in the rotation process because cam below so that activity compressed part 2 slowly descend, upper end 21 is close to upper end 21 with workpiece surface afterwards, supporting surface 11 and Level tune piece 4 cooperate realizes gripping workpiece.
Above-described only is embodiments of the invention, and the general knowledge such as known concrete structure and characteristic are not done too much description at this in the scheme.Should be understood that; for a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
