Constant defeat on chip with one, chip is contacted completely with SOCKET, and allowing the transmission of signal not be interrupted is that manually pressure surveys an application principle of device.In existing design as shown in Figure 1, it is by rotary screw that the pressure of chip is surveyed, and utilizes the pretightning force of screw thread that chip is pressed on the test position of SOCKET.This design Problems existing is, when rotary screw touches chip to be measured and compressed by chip time, chip can be made to relatively rotate on position to be measured, the friction of generation can scratch the surface of chip, reduce the serviceable life of chip, the some position of test is offset.Unclamp rotary screw, can make chip and SOCKET that relative rotation occurs equally, cause the scuffing of chip, reduce the serviceable life of chip and the some position of impact test.
Utility model content
Utility model object: for the problems referred to above, the purpose of this utility model is to provide a kind of manual pressure that be easy to operation, that do not damage chip and surveys device.
Technical scheme: a kind of manual chip pressure surveys device, comprise screw, locating piece, SOCKET, test board, limited block, pressure gauge head, spring, described locating piece is provided with square slideway, described pressure gauge head is arranged in described square slideway, described pressure gauge head is connected with described locating piece by described spring, described limited block is connected with described locating piece, described locating piece is connected with described test board, described SOCKET to be arranged on immediately below described square slideway and to be connected with described test board, and described limited block is provided with hole, and described screw is arranged in described hole.
Further, described pressure gauge head is square stepped, and with described square slideway clearance fit, make pressure gauge head can be freely movable and there will not be stuck phenomenon in square slideway.
Further, described square slideway inwall offers counterbore one, and described pressure gauge head is provided with counterbore two, and described counterbore one and described counterbore two position, quantity are corresponding, and diameter is identical; Be provided with spring in corresponding described counterbore one, described counterbore two, counterbore arrange can restraining spring motion time bullet fly, to ensure to press the straight line of gauge head to press down and resilience, make pressure gauge head and chip not produce relative motion.
Further, described counterbore one, described counterbore two have two at least.
Further, described locating piece, described limited block, described pressure gauge head all adopt insulation aluminum alloy material and anodized has been carried out on surface, to ensure that pressure survey device meets corresponding hardness requirement and smooth surface does not scratch chip.
Beneficial effect: compared with prior art, the utility model has the advantages that achieving pressure surveys device from the screw type progress being depressed into straight line and pressing down, chip is well prevented to produce scuffing because of friction, and the skew of test point position can be prevented, extend the serviceable life of chip, and do not affect the degree of accuracy of test, be easy to operation.

Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As illustrated in figs. 2 through 8, a kind of manual chip pressure surveys device, comprises screw 1, locating piece 2, SOCKET3, test board 4, limited block 5, pressure gauge head 6.In order to make pressure gauge head 6 press down in a linear fashion and resilience, establish a square slideway 7 in locating piece 2 central authorities, square slideway 7 inwall relative position offers two counterbores 1.
Measuring head 6 aluminium alloy makes, and anodized has been carried out on surface, and what be designed to match with square slideway 7 gap is square stepped, establishes two counterbores 2 10 in the both sides of measuring head 6 ground floor ladder with the corresponding position of counterbore 1 in square slideway 7.Counterbore 1 is identical with counterbore 2 10 diameter, in order to lay spring 11.For ensureing that spring 11 is not flown by bullet or moves in compression process, its upper and lower side is placed in corresponding counterbore 1, counterbore 2 10 respectively, connects pressure gauge head 6 and locating piece 2.
Limited block 5 is arranged on above pressure gauge head 6, hole 8 and pressure gauge head 6 central alignment of limited block 5 central authorities.Limited block 5 four jiaos is fixed with bolt and locating piece, and hole 8 is threaded, and matches with screw 1.SOCKET3 is arranged on test board 4, and its position is positioned at immediately below square slideway, and SOCKET3 central authorities align with the tip of pressure gauge head 6.Four pin of locating piece 2 are fixed on position corresponding on test board 4.In order to not have an impact to test result, keep due hardness, locating piece 2, limited block 5 are all made with insulation aluminum alloy material, and anodized has been carried out on surface.
Pressure surveys device in use, say that locating piece 2 four pin is fixed on test board 4, chip 12 is positioned in the central socket of SOCKET3, rotate forward screw 1, screw 1 extrudes pressure gauge head 6, and spring 11 is compressed, and pressure gauge head 6 straight line is pressed down, until pressure gauge head 6 tip contacts the constant power of applying one with chip, test.End to be tested, only needs Negative selection screw 1, and the resilience under the effect of spring 11 of pressure gauge head 6, leaves chip 12.Survey compared with device with original pressure, what apply pressure gauge head 6 is only power in vertical direction, does not produce relative motion, avoids the loss to chip 12 surface, extend its life-span with chip 12.
