One clamping device 3, comprise shaft-like the first clamp 311, the second clamp 312 be located in 2 liang of horizontal guide grooves 22 of described workbench, and be located at the 3rd clamp 313, the 4th clamp 314 in two vertical guide grooves 23, the height of the first clamp 311, the second clamp 312, the 3rd clamp 313, the 4th clamp 314 protrudes from one section suitable spacing of workbench 2 upper surfaces, and this equidistantly jointly is enclosed to form one and is available for determinand and places this place to be subjected between the positioning area of the first clamp 311, the second clamp 312, the 3rd clamp 313, the 4th clamp 314 common sandwiched location 31;

One driving mechanism 4, the actuator 41 that is made of a vapour pressure cylinder of being located on the base 1 drives, make described the first clamp 311, the second clamp 312, the 3rd clamp 313, the 4th clamp 314 can be synchronously to 31 moving by the clamping determinand or separate to loosen the clamping to determinand between described positioning area.

See also Fig. 2, be positioned at described the first clamp 311 transversely, the second clamp 312 is on synchronous shift, the first moving part 42 is vertically being drawn or promoted in system by this actuator 41 with connecting rod 411, make and be fixedly arranged on that the first moving part 42 and base 1 vertically arrange the first slide 321 on the first slide rail 32 and before also doing vertically with the transverse axis actuator 43 of its interlock, rear displacement, because the first clamp 311, the second clamp 312 is located at respectively can be on the second slide 331 of slippage on the second slide rail 33 of base 1 horizontally set, and be located on the 3rd slide 341 of slippage on the 3rd slide rail 34 of base 1 horizontally set, and the first clamp 311, the second clamp 312 is the pivot oblique closure of offering first guide channel 431 on this transverse axis actuator 43 respectively, the second guide channel 432, at the first guide channel 431, the two is shorter in vertical rear side spacing for the second guide channel 432, and the two is wider in vertical front side spacing, and under the design of gradient correspondence identical (being all 45 degree with longitudinal axis angle), therefore, the first moving part 42 interlock transverse axis actuators 43 vertically move forward, to make the first guide channel 431, the second guide channel 432 orders about the first clamp 311, the second clamp 312 outward synchronously away from, on the contrary, when the first moving part 42 interlock transverse axis actuators 43 move after vertically, will make the first guide channel 431, the second guide channel 432 orders about the first clamp 311, the second clamp 312 is close toward inter-sync.

See also Fig. 3, described the 3rd clamp 313 on being positioned at vertically, the 4th clamp 314 are on synchronous shift, wherein the 4th clamp 314 is vertically to draw or promoting the first moving part 42 by this actuator 41 with connecting rod 411, make the base 1 that sets firmly with the first moving part 42 that the 4th slide 322 vertically is set on the first slide rail 32 and also do vertical forward and backward displacement, and make the 4th clamp 314 synchronous length travels that are fixedly arranged on the 4th slide 322;

The displacement of the 3rd clamp 313, system by this actuator 41 with connecting rod 411 when vertically drawing or promoting the first moving part 42, because the base 1 in the first moving part 42 the place aheads is provided with the swing arm 5 that can do swing take pivot 51 as rotating shaft, and swing arm 5 more offers the first pivot groove 52 and the second pivot groove 53 in both sides, pivot 51 axle center equidistant; Wherein, the first pivot groove 52 is pivoted wherein for described the first moving part 42 front sides one projection seat, 421 upper bearing (metal)s 422, and the second pivot groove 53 then provides is located at that the 3rd clamp 313 of the 5th slide 323 is pivoted wherein on the first slide rail 32; Therefore, during the first moving part 42 displacement forward, projection seat 421 upper bearing (metal)s 422 will be stirred swing arm 5 and be rotated counterclockwise rotation centered by pivot 51, make the swing arm opposite side do oppositely to pass with the second pivot groove 53 the 3rd clamp 313 of wherein being located on the first slide rail 32 the 5th slide 323 that will be pivoted, even the 3rd clamp 313 carries out the operation of clamping determinand backward; Otherwise, during the first backward displacement of moving part 42, projection seat 421 upper bearing (metal)s 422 will be stirred swing arm 5 rotation that turns clockwise centered by pivot 51, make the swing arm opposite side do oppositely to pass with the second pivot groove 53 the 3rd clamp 313 of wherein being located on the first slide rail 32 the 5th slide 323 that will be pivoted forward, even the 3rd clamp 313 unclasps the operation of determinand.

Because the first pivot groove 52 and the second pivot groove 53 are in both sides, pivot 51 axle center equidistant in the swing arm 5, and make in the design upper bearing (metal) 422 and the 3rd clamp 313 in both sides, distance pivot 51 axle center also for equidistantly, therefore, the distance of the first moving part 42 interlocks the 3rd clamp 313 displacements is consistent with the distance of interlock the 4th clamp 314 displacements; Certainly the distance that also is equal to the first clamp 311,312 displacements of the second clamp.

Design of the present utility model, provide the clamping fixture of checkout equipment can be only with the driving of an actuator 41, it is the operation that simultaneous linkage the first clamp 311, the second clamp 312, the 3rd clamp 313, the 4th clamp 314 carry out clamping synchronously, unclasp, fully reach and make each determinand when inserting tested district each time, can (1) locate immediately; (2) be positioned at the function of same accurate fixed point so that can reduce in the process that measures each time, not even with adjusting again test measuring device, to cooperate the requirement such as a large amount of auto-measurings of automation of hand set machine shell etc.

The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in the scope of patent protection of the present utility model.
