Abstract
The utility model relates to the technical field of workpiece positioning fixtures, in particular to a clamping fixture. The clamping fixture comprises a worm, a left worm gear, a right worm gear, a hand-cranking wrench, two swing rods and two pressure blocks. The worm is connected with the hand-cranking wrench and respectively in transmission connection with the left worm gear and the right worm gear, one ends of the two swing rods are rotatably connected with the two pressure blocks respectively, and the other ends of the two swing rods are rotatably connected with the left worm gear and the right worm gear respectively. Compared with the prior art, the clamping fixture has the advantages of simple structure, low production cost and a self-locking function.
Description
Technical field
The utility model relates to the technical field of workpiece positioning clamp, particularly a kind of clamping device.
Background technology
Machine-building be unable to do without Metal Cutting Machine Tool, and jig is to ensure mechanical processing quality, enhance productivity, reduce labor intensity, reduce excessive demand to workman's technology, realize one of indispensable important process equipment of Automation of Manufacturing Process.Jig is widely used in manufacturing industry, and the use of a large amount of special jigs provides necessary condition for producing in enormous quantities.In the past, when workpiece is finished after line, installed by line with chuck, reprocessed endoporus.In the process of proofreading and correct, to adjust while being clipped in two pawl on the face of cylinder, workpiece can roll, and the center line in the hole that makes to rule produces angle displacement, is difficult to workpiece correction, easily produces waste product.People have manufactured and designed fixture for this reason, and still, the structure of fixture is more complicated at present, and production cost is higher.
Utility model content
The utility model object is to provide a kind of clamping device, more complicated to solve the structure of fixture of the prior art, the technical matters that production cost is higher.
The utility model object realizes by following skill scheme:
A kind of clamping device, comprise worm screw, left worm gear, right worm gear, hand spanner, two forks and two briquettings, described worm screw is connected with described hand spanner, described worm screw is connected with described left worm gear, described right worm-drive respectively, one end of two forks is rotatably connected with two briquettings respectively, and the other end of two forks is rotatably connected with described left worm gear and described right worm gear respectively.
Preferably, also comprise casing, described worm screw, described left worm gear and described right worm gear are arranged in described casing, and the downside of described casing is provided with and can holds the slotted eye that described fork passes.
Preferably, also comprise limit body, described briquetting is arranged in the spacing hole of described limit body.
Preferably, one end of described fork is connected by pin with described briquetting.
Compared with prior art, the utility model has following beneficial effect:
Clamp structure of the present utility model is simple, and production cost is low, also has auto-lock function.
Brief description of the drawings
Structural representation when Fig. 1 is clamping device use of the present utility model.
Detailed description of the invention
Describe the utility model in detail below in conjunction with drawings and Examples.
Refer to Fig. 1, a kind of clamping device of the present utility model, comprise worm screw 3, left worm gear 2, right worm gear 4, hand spanner 1, casing 5, two forks 6 and two briquettings 7, worm screw 3 is connected with hand spanner 1, worm screw 3 is in transmission connection with left worm gear 2, right worm gear 4 respectively, one end of two forks 6 is rotatably connected by pin with two briquettings 7 respectively, and the other end of two forks is rotatably connected with left worm gear 2 and right worm gear 4 respectively.Worm screw 3, left worm gear 2 and right worm gear 4 are arranged in casing 5, and the downside of casing 5 is provided with and can holds the slotted eye that fork 6 passes.
In the present embodiment, also comprise limit body 9, briquetting 7 is arranged in the spacing hole of limit body 9, and briquetting 7 can only be moved up and down, and can not before and after and move left and right.
When use, first workpiece 8 is placed on table top, fixes the position of limit body 9, briquetting 7 is arranged in the spacing hole of limit body 9, briquetting 7 is pressed on workpiece 8, rotate hand spanner 1, drive worm screw 3 to rotate, thereby drive left worm gear 2 and right worm gear 4 to rotate dorsad simultaneously, and then drive briquetting 7 to move downward, thereby workpiece 8 is compressed, now, can carry out process operation to workpiece.After process operation, the hand spanner 1 of counter-rotation, can take out workpiece 8.
Clamp structure of the present utility model is simple, and production cost is low, also has auto-lock function.
Disclosed is above only several specific embodiments of the application, but the application is not limited thereto, and the changes that any person skilled in the art can think of, all should drop in the application's protection domain.
