The specific embodiment
By particular specific embodiment, embodiment of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this description.
Refer to Fig. 1,2.Notice, appended graphic the illustrated structure of this description, ratio, size etc., all contents in order to coordinate description to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this description, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
As shown in Figure 2, the utility model provides a kind of pipe clamp to grip mechanism, and this pipe clamp grips mechanism and comprises an arc back-up block 1, workpiece depression bar 2, push-and-pull guide rod 4, linkage and cam 9.Arc back-up block 1 is fixed on support 8, and the outer peripheral face of arc back-up block 1 is arc, adapts with the inner peripheral surface shape of pipe clamp, and pipe clamp can directly be stuck on this arc back-up block.The middle part dumpling of workpiece depression bar 2 props up on support 8, one end of workpiece depression bar 2 is provided with hold-down head 3, the position of hold-down head 3 is relative with the position of arc back-up block outer peripheral face, the other end of workpiece depression bar 2 is connected with one end of push-and-pull guide rod 4 by linkage, and the other end of push-and-pull guide rod 4 is resisted against on cam 9.When push-and-pull guide rod 4 moves along cam 9 outer peripheral faces, push-and-pull guide rod 4 itself can moving linearly, and by linkage drive hold-down head 3 along near or move around away from the direction of arc back-up block 1.
As a kind of optimal way, linkage comprises first connecting rod 5, second connecting rod 7 and third connecting rod 6, one end of first connecting rod 5 and push-and-pull guide rod 4 are hinged, one end of the other end and second connecting rod 7, third connecting rod 6 is hinged by same bearing pin, the other end of second connecting rod 7 is hinged on support 8, and the other end of third connecting rod 6 and workpiece depression bar 2 are hinged away from one end of hold-down head 3.Like this in the time that push-and-pull guide rod 4 moves down, promotion first connecting rod 5 is moved down, due to the mutual support of second connecting rod 7, third connecting rod 6,5 of first connecting rods can move down, can not rotate, so just can drive two connecting rods 7, third connecting rod 6 outwards to strut, third connecting rod 6 drives one end of workpiece depression bar 2 to move up, and then move towards the direction near arc back-up block 1 one end that makes workpiece depression bar 2 be provided with hold-down head.In like manner, in the time that push-and-pull guide rod 4 moves up, one end court that drives workpiece depression bar 2 to be provided with hold-down head is moved away from the direction of arc back-up block 1.
Can be in the ganoid movement of cam 9 in order to make push-and-pull guide rod 4 be resisted against one end of cam 9, one end that push-and-pull guide rod 4 is resisted against cam 9 is provided with rolling bearing 10, and rolling bearing 10 is arranged in bearing block.
In order to make the push-and-pull guide rod 4 can smooth and easy movement, on push-and-pull guide rod 4, be also provided with a guide pin bushing assembly 11, guide pin bushing assembly 11 is fixed on base, push-and-pull guide rod 4 is through this guide pin bushing assembly 11, guide pin bushing assembly 11 can play certain guide effect to push-and-pull guide rod 4, can move around along straight line smoothly.
For being resisted against on cam 9 of making that one end of push-and-pull guide rod 4 can be real-time, push-and-pull guide rod 4 is also connected with a back-moving spring 12, back-moving spring 12 is enclosed within on push-and-pull guide rod 4, push-and-pull guide rod 4 is provided with a baffle plate 13 in the side near cam 9, back-moving spring 12 is between baffle plate 13 and guide pin bushing assembly 11, back-moving spring 12 just can provide thrust to push-and-pull guide rod 4 by baffle plate like this, can be real-time be resisted against on cam 9, so just can control the degree of depth that hold-down head 3 presses down by controlling the position of push-and-pull guide rod 4 on cam 9.
This pipe clamp grips mechanism in use, first pipe clamp is placed on arc back-up block, make the inner peripheral surface of pipe clamp and the laminating of the outer peripheral face of arc back-up block, then make the other end of push-and-pull guide rod move along cam face, make the rectilinear movement of push-and-pull guide rod, in the time that push-and-pull guide rod moves to one end of cam, push-and-pull guide rod drives hold-down head to press down by linkage, make hold-down head push down pipe clamp, so just pipe clamp can be fixed on arc back-up block and polish; After pipe clamp has been polished, then make the other end of push-and-pull guide rod move along cam face, in the time that push-and-pull guide rod moves to the other end of cam, push-and-pull guide rod is mobile backward unclamps hold-down head, so just can very easily pipe clamp be taken off from arc back-up block.It is simple that this pipe clamp grips mechanism structure, easy to use, can effectively improve the polishing speed of pipe clamp, enhances productivity.So the utility model has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under such as and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
