Description

Tool for realizing repeated positioning of machining

[ technical field ] A method for producing a semiconductor device

The utility model relates to a machine tooling location technical field, specific saying so, a realize frock of machine tooling repeated location.

[ background of the invention ]

When the trial processing of the sample piece is carried out on the processing center, because the machining process and the processing parameters are not completely determined, the sample piece is often processed on a machine tool according to the preset parameters, then the sample piece is disassembled for size detection, if the measurement result is unqualified, the machining process and the processing parameters need to be changed for re-processing, and thus the cyclic work of processing, detection, debugging and re-processing is formed until the processed sample piece is qualified. During secondary and repeated processing, re-clamping, tool setting, meter printing correction and the like are needed, long time is consumed during each clamping, the precision of re-clamping is difficult to guarantee, and finally high rejection rate of sample pieces is caused.

[ Utility model ] content

An object of the utility model is to overcome prior art's is not enough, provide a frock that realizes machine tooling repeated location. The tool can effectively reduce clamping time, guarantee clamping precision and effectively reduce the debugging rejection rate of the sample, thereby reducing the comprehensive processing cost.

The purpose of the utility model is realized through the following technical scheme:

a tool for realizing repeated positioning of machining comprises a handle, a lead screw, a guide rail, a sliding clamping block, a transition plate, a pin and a fixed clamping block; the handle is arranged at the end part of the screw rod through a key; the guide rail is fixedly connected with the horizontal table through a bolt; the sliding clamping block is connected with the guide rail through a bottom sliding chute and is connected with the screw rod through a middle threaded hole; the transition plate is connected with the fixed clamping block through a pin.

The sample piece is connected and fixed with the transition plate.

The two ends of the screw rod are respectively connected with the fixed clamping blocks of the supporting frame through bearings, the middle of the screw rod is connected with the sliding clamping block through threads, and the screw rod can drive the sliding clamping block to move back and forth by rotating.

The locking knob is arranged on the support frame through a bolt

The sliding clamping block is connected with the guide rail through a bottom sliding groove and connected with the screw rod through a middle threaded hole, and the sliding clamping block moves back and forth along the guide rail under the driving of the screw rod.

Compared with the prior art, the utility model has the positive effects that:

when the tool is used for clamping, tool setting, meter printing correction and the like are not needed again, so that the clamping time is obviously reduced, the clamping precision can be effectively guaranteed, and the qualification rate of sample pieces is improved.

[ detailed description ] embodiments

The following provides the utility model relates to a realize the concrete implementation mode of frock of machine tooling repeated positioning.

Example 1

Referring to fig. 1 and fig. 2, a tool for realizing repeated positioning in machining includes a handle, a screw, a rail slide clamp block, a transition plate, a pin and a fixed clamp block; the handle 10 is arranged at the end part of the screw rod through a key; the guide rail is fixedly connected with the horizontal table through a bolt; the sliding clamping block 5 is connected with the guide rail 6 through a bottom sliding chute and is connected with the screw rod 9 through a middle threaded hole; the transition plate 2 is connected with the fixed clamping block 3 through a pin 4.

The sample piece 1 is fixedly connected with the transition plate 2.

Two ends of the screw rod are respectively connected with the fixed clamping blocks of the supporting frame 7 through bearings, the middle of the screw rod is connected with the sliding clamping blocks through threads, and the screw rod can drive the sliding clamping blocks to move back and forth by rotating.

The locking knob 8 is arranged on the support frame through a bolt

When the tool is used for machining, the sample piece and the transition plate are connected and fixed, wherein the part of the sample piece to be machined needs to be staggered with the transition plate according to specific conditions, and the interference of the transition plate during machining is avoided. For example, if a plane is milled on the upper surface of the middle boss of the sample and a hole is machined at the center position of the middle boss (as shown in fig. 1), the middle boss of the sample needs to be staggered from the transition plate to prevent the milling cutter from interfering with the transition plate when the plane is milled. For different sample pieces and processing parts, the size and the structure of the transition plate are different, but the transition plate is provided with two pin holes which are mainly used for positioning through two pins (a cylindrical pin 12 and a diamond pin 11) and a fixed clamping block on the tool. After the transition plate and the fixed clamping block are positioned through the pin, the handle is rotated, the sliding clamping block is driven to slide along the guide rail through the lead screw until the workpiece and the transition plate are clamped on the fixed clamping block, and finally clamping and positioning of the sample piece are achieved. After the sample piece is cut, the handle is rotated reversely, so that the two clamping blocks are loosened, and the sample piece and the transition plate are taken down together for detection. If the sample piece is unqualified after detection, the sample piece can be directly installed according to the installation method for processing, and the sample piece is clamped and processed for many times until the sample piece is qualified. When the tool is used for clamping, tool setting, meter printing correction and the like are not needed again, so that the clamping time is obviously reduced, the clamping precision can be effectively guaranteed, and the qualification rate of sample pieces is improved.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the concept of the present invention, and these improvements and decorations should also be considered as within the protection scope of the present invention.
