Abstract
The utility model relates to a clamping device, in particular to a two-arm clamping device. The two-arm clamping device comprises a base provided with a clamping platform, clamping arms with clamping heads, bolts and compression springs. The upper end of each bolt is connected with the base. The middle portion of each clamping arm is provided with an arc-shaped long hole. The clamping arms and shaft pins matched with the long holes in the clamping arms are arranged on the two sides of the base. The two-arm clamping device further comprises a sliding sleeve and two supporting rods. The bolts penetrate through the sliding sleeve, one end of each supporting rod is connected with the sliding sleeve, and the other end of each supporting rod is hinged to one end, far from the clamping head, of each clamping arm. The compression springs are arranged on the bolts between the sliding sleeve and the base in a sleeved mode, and gland nuts are arranged at the lower ends of the bolts. The two-arm clamping device can reduce extrusion acting force between workpieces and the clamping platform in the process of clamping the workpieces, thereby effectively protecting the workpieces.
Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of both arms clamping device.
Background technology
In machine tooling, conventionally after need to using clamp mechanism that workpiece is fixing, carry out again follow-up processing, so clamp mechanism is widely used in workpiece manufacture field, and existing clamp mechanism shortcoming is: workpiece is positioned on grain-clamping table, pressing plate is exerted pressure at surface of the work, and the power that workpiece and grain-clamping table contact-making surface push is mutually larger, a facial disfigurement that easily makes workpiece contact with grain-clamping table.
Utility model content
The defect existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of both arms clamping device, and this clamping device, in the process of holding workpiece, can reduce the squeezing action power between workpiece and grain-clamping table, so can effectively protect workpiece.
For achieving the above object, the technical solution of the utility model is: both arms clamping device, comprise the pedestal with grain-clamping table, clamping limb, bolt and the Compress Spring with clamping head, described bolt upper end is connected with pedestal, wherein, described clamping limb middle part is provided with the slotted hole of arc, the pivot pin that described pedestal both sides are equipped with clamping limb and coordinate with the slotted hole of clamping limb; Also be provided with sliding sleeve and two struts, described sliding sleeve is by bolt-through, and two strut one end are all connected with sliding sleeve, and the other end is hinged with two clamping limb clamping head far away one end respectively; Described Compress Spring is sheathed on the bolt between sliding sleeve and pedestal, and bolt lower end is provided with clamp nut.
While adopting technique scheme, tighten clamp nut, clamp nut upwards promotes sliding sleeve, and meanwhile, the strut being connected on sliding sleeve moves up, now with on the hinged clamping limb in strut clamping head far away one end move, and clamping head one end inwardly swings, thus from both sides by piece-holder, in addition, two clamping limbs are also applied with component upwards on workpiece, have so just reduced the active force mutually pushing between workpiece and grain-clamping table.The utility model, in the process of holding workpiece, can reduce the squeezing action power between workpiece and grain-clamping table, so can effectively protect workpiece.
Further, the hinged end of described strut is higher than the one end being connected with sliding sleeve, when strut is upwards propped up clamping limb, larger power is born in strut and sliding sleeve junction, when the hinged end of strut is when with sliding sleeve link, clamping limb puts on a power part on the strut direction along strut, so can reduce the power of strut and sliding sleeve junction, is not easy rhegma.
Further, between described clamp nut and sliding sleeve, be provided with spheric washer, tighten or unscrew in clamp nut process, spheric washer can be avoided clamp nut and pressing plate direct friction, thus not only can reduce the wearing and tearing of pressing plate, and it is convenient to change spheric washer.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model both arms clamping device embodiment.
The specific embodiment
As shown in Figure 1, a kind of both arms clamping device, comprise the pedestal 1 with grain-clamping table, the clamping limb 7 with clamping head, bolt 2 and Compress Spring 6, bolt 2 upper ends are connected with pedestal 1, wherein, clamping limb 7 middle parts are provided with the slotted hole 71 of arc, the pivot pin that pedestal 1 both sides are equipped with clamping limb 7 and coordinate with the slotted hole 71 of clamping limb 7; Also be provided with sliding sleeve 4 and two struts 5, sliding sleeve 4 is run through by bolt 2, and two strut 5 one end are all connected with sliding sleeve 4, and the other end is hinged with two clamping limbs, 7 clamping head far away one end respectively; Compress Spring 6 is sheathed on the bolt 2 between sliding sleeve 4 and pedestal 1, and bolt 2 lower ends are provided with clamp nut 3, between clamp nut 3 and sliding sleeve 4, is provided with spheric washer.
Specific works flow process:
As shown in Figure 1, be illustrated as the state that clamping limb 7 clamps workpiece 8.Upwards tighten clamp nut 3, clamp nut 3 upwards promotes sliding sleeve 4, simultaneously, the strut 5 being connected on sliding sleeve 4 moves up, and now with on the hinged clamping limb 7 in strut 5 clamping head far away one end move, and clamping head one end inwardly swings, thereby clamp from both sides by workpiece 8, in addition, two clamping limbs 7 are also applied with component upwards on workpiece 8, have so just reduced the active force mutually pushing between workpiece 8 and grain-clamping table.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of 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 affect effect and practical applicability that the utility model is implemented.
