Abstract
The utility model provides a connecting rod formula clamping device, includes fixing base, swing hydro-cylinder, briquetting subassembly and the digging arm that is connected with them, the digging arm comprises rotation scute, pitman arm, pressure plate arm, becomes the rotary type by the round pin axle each other and connects, the briquetting subassembly is adjustable briquetting mechanism, comprises regulation pole, lock nut, briquetting. The utility model is used for press from both sides tight work piece in the machining, when pressing from both sides tightly, the fulcrum that the pitman arm both ends fulcrum is connected in the fixing base with rotatory scute is located same straight line, is in the auto-lock state, and hydro-cylinder hydrovalve valve position control in addition realizes the dual locking function, therefore not only the clamp force is big, presss from both sides tight good reliability moreover, is particularly useful for the cutting force big, and the tight occasion of processing clamp that the amplitude is big.
Description
Technical field
The utility model relates to a kind of clamping device that is used for machining, especially contains the link-type clamping device of oil cylinder, lever arm.
Background technology
In field of machining, varied to the clamp mechanism of workpiece, lever, Wedge type, screw, the various clamp mechanism of eccentric wheel type are arranged, but they are big for cutting force, the clamping occasion that amplitude is big also is not suitable for.A kind of link-type clamping mechanism that is driven by hydraulic jack is arranged, though clamping force is bigger, mechanism itself can not self-locking, and clamped position only has single lock function by the valve position control of hydraulic valve, and clamping reliability is relatively poor.
The utility model content
It is big that the technical problems to be solved in the utility model provides a kind of clamping force, the link-type clamping device that clamping reliability is good.
The technical solution of the utility model is: the link-type clamping device, comprise holder, oscillating oil cylinder, briquetting assembly and the lever arm that is connected with them, improvements are that described lever arm is by the rotation gusset, pitman arm, platen arm constitutes, the rotation gusset by 3 on same straight line not respectively with holder, one end of oscillating oil cylinder piston rod and pitman arm is connected, the other end of pitman arm is connected with platen arm, one end of platen arm is connected with holder, the above connecting portion is equipped with bearing pin, constituting rotary type connects, described briquetting assembly is adjustable forming machanism, is arranged on the other end of platen arm.
Above-mentioned adjustable forming machanism is made of adjusting rod, locking nut, briquetting, and adjusting rod is threaded with platen arm, and adjusting rod head and briquetting cooperation place are sphere.
When the utility model uses, the rotation gusset rotates under hydraulic oil cylinder driving, the drivening rod arm rotates, by platen arm, forming machanism workpiece pressing, when being in clamped condition, the fulcrum at pitman arm two ends is located along the same line with the fulcrum that the rotation gusset is connected in holder, make this linkage be in self-locking state, add the valve position control of hydraulic valve, realize double locking function, therefore, this installs, and not only clamping force is big, and clamping reliability is good, is particularly useful for the machined that cutting force is big, amplitude is big and clamps occasion.
Description of drawings
Structural representation when Fig. 1 is the utility model clamped condition;
Structural representation when Fig. 2 is the utility model releasing orientation.
The specific embodiment
Referring to accompanying drawing, rotation gusset 3 is by 3 A, E on same straight line, B are not connected with the piston rod of holder 1, oscillating oil cylinder 2 and an end of pitman arm 4 respectively, the other end of pitman arm 4 is connected with platen arm 5 by fulcrum C, one end of platen arm 5 is connected with holder by fulcrum D, each connecting portion all has bearing pin, constitutes rotary type and connects, and the other end of platen arm 5 is threaded with adjusting rod 6, and locking nut 7 is arranged, adjusting rod head and briquetting 8 cooperation places are sphere.During clamping, the oil cylinder piston bar protracts, and drives the rotation gusset and is rotated counterclockwise around the A point, drivening rod arm, platen arm rotate around B, D point respectively, and briquetting presses down, and regulates the adjusting rod position and tightens locking nut, when workpiece 9 was clamped, A, B, C were positioned at same straight line; When unclamping, piston rod retreats, and rotation gusset, pitman arm, platen arm backward rotation are lifted to eminence briquetting.
Claims (2)
1, a kind of link-type clamping device, comprise holder, oscillating oil cylinder, briquetting assembly and the lever arm that is connected with them, it is characterized in that described lever arm is by the rotation gusset, pitman arm, platen arm constitutes, the rotation gusset by 3 on same straight line not respectively with holder, one end of oscillating oil cylinder piston rod and pitman arm is connected, the other end of pitman arm is connected with platen arm, one end of platen arm is connected with holder, the above connecting portion is equipped with bearing pin, constituting rotary type connects, described briquetting assembly is adjustable forming machanism, is arranged on the other end of platen arm.
2, by the described link-type clamping device of claim 1, it is characterized in that described adjustable forming machanism is made of adjusting rod, locking nut, briquetting, adjusting rod is threaded with platen arm, and adjusting rod head and briquetting cooperation place are sphere.
