Abstract
The utility model discloses a clamping device and particularly relates to a pneumatic-type raised head clamping device. The pneumatic-type raised head clamping device comprises a clamp body, a toggle lever mechanism, a cylinder body which can move left and right in a back-and-forth mode on the clamp body, a supporting block which supports a workpiece, and a clamping jaw which tightly clamps the workpiece. The clamping jaw comprises a driven end and a driving end, wherein the driven end plays a clamping role, and the driving end plays a force application role. The driven end of the clamping jaw is connected with a raised head which is used for tightly pressing the upper surface of the workpiece. The middle portion of the clamping jaw is hinged with the clamp body. The supporting block is connected with the clamp body through a locating pin. The cylinder body is connected with the clamp body through a strong spring. The toggle lever mechanism comprises an upper toggle lever and a lower toggle lever, wherein the upper toggle lever and the lower toggle lever are connected with the cylinder body through pin rollers and pins, and the top end of the upper toggle lever is hinged with the driving end of the clamping jaw. According to the pneumatic-type raised head clamping device, a pneumatic device is used for providing motive power, and the pneumatic-type raised head clamping device has the basic advantages that the clamping force is constant, the clamping action is fast, and the technical problems that an existing clamping device is slow in clamping action and inconstant in clamping force are solved.
Description
Technical field
The utility model relates to a kind of clamping device, especially a kind of pneumatic type plush copper clamping device.
Background technology
The lathe clamping device be on lathe in order to a kind of device of clamping workpiece, its effect is with the workpiece location, so that workpiece obtains the tram of relative lathe or cutter, and workpiece is clamped reliably.Can not destroy the tram that workpiece occupies during clamping in anchor clamps, clamping force is wanted suitably, should guarantee that workpiece is not mobile in process, does not rotate, do not vibrate, do not make surface of the work damage, distortion again because clamping force is excessive, structure should be tried one's best simply, makes, keeps in repair and will make things convenient for, the operation of clamp mechanism should safety, convenient, rapidly, laborsaving.Therefore, the raising of clamping device and operating personnel's improvement and machine tool capability has close relationship.Usually use vice to clamp in the prior art, the power of clamping by workman's experience, clamps slow motion entirely, clamping force is non-constant, and therefore, the workpiece accuracy that processes is relatively poor.
The utility model content
Technical problem to be solved in the utility model provides the clamping device that a kind of clamping force is constant, clamping is swift in motion.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of pneumatic type plush copper clamping device, comprise chuck body, elbow-bar mechanism, can be on chuck body the left and right cylinder block that moves around, play the jaw of clamping action to the passive back-up block of workpiece, to workpiece; Described jaw has comprised the driven end of clamping action and has played the drive end of application of force effect, the driven end of jaw connects the plush copper that is used for the workpiece pressing upper surface, the jaw middle part is hinged with chuck body, back-up block is connected with chuck body by alignment pin, and cylinder block is connected with chuck body by brute spring; Described elbow-bar mechanism comprises upper elbow lever and lower elbow lever, and upper and lower toggle link is connected with cylinder block with pin by roller, and the top of upper elbow lever and the drive end of jaw are hinged.
The course of work of the present utility model:
During cylinder activation, cylinder block is to left movement, and cylinder block promotes upper elbow lever and clockwise rotates around the center of upper elbow lever, and the drive end that upper elbow lever drives jaw moves upward, thereby makes the plush copper clamping work pieces that links to each other with the jaw driven end.
When cylinder disconnected, cylinder block moved right under the effect of brute spring, and cylinder block drives upper elbow lever and rotates counterclockwise around the center of upper elbow lever, and the drive end that upper elbow lever drives jaw moves downward, thereby makes the plush copper that is connected with the driven end of jaw unclamp workpiece.
Adopt the utility model that following technique effect is arranged:
1, adopt pneumatic means as power source, clamping is swift in motion, and clamping force is constant.
2, the shape of back-up block and big I are regulated according to shape and the size of workpiece, and therefore, this clamping device can be used for processing the workpiece of difformity and size.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model pneumatic type plush copper clamping device.
The specific embodiment
As shown in Figure 1, pneumatic type plush copper clamping device of the present utility model, comprise chuck body 1, elbow-bar mechanism, can be on chuck body 1 the left and right cylinder block that moves around 2, play the jaw 3 of clamping action to the passive back-up block 42 of workpiece, to workpiece; Described jaw 3 has comprised the driven end 32 of clamping action and has played the drive end 31 of application of force effect, the driven end 32 of jaw 3 connects the plush copper 41 that is used for the workpiece pressing upper surface, jaw 3 middle parts and chuck body 1 are hinged, back-up block 42 is connected with chuck body 1 by alignment pin 43, and cylinder block 2 is connected with chuck body 1 by brute spring 8; Described elbow-bar mechanism comprises upper elbow lever 51 and lower elbow lever 52, upper elbow lever 51 is connected with cylinder block 2 with pin 7 by roller 6 with lower elbow lever 52, the drive end 31 of the top of upper elbow lever 51 and jaw 3 is hinged, makes the plush copper clamping or unclamps workpiece thereby cylinder block 2 left and right motions drive upper elbow lever 51 upper and lower motions.The shape of back-up block 42 and big I are regulated according to shape and the size of workpiece.
Above-described only is preferred embodiment of the present utility model, should be pointed out that for a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement.These also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
Claims (1)
