[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0016] According to the positioning device for processing the paving machine screed support according to the embodiment of the utility model, Figure 1As shown, the fixture includes a fixture body 10, a first vertical positioning block 20, a second vertical positioning block 30 and a horizontal fixing stud 40; a connecting surface 11 and four working surfaces 12 are provided on the fixture body 10; the connecting surface 11 is connected to the upper surface of the machine tool worktable; there are four first vertical positioning blocks 20, and the four first vertical positioning blocks 20 are respectively arranged at the first upper side ends of the four working surfaces 12; there are four second vertical positioning blocks 30, and the four second vertical positioning blocks 30 are respectively arranged at the first lower side ends of the four working surfaces 12; there are twelve horizontal fixing studs 40, and the twelve horizontal fixing studs 40 are respectively arranged at the second upper side ends, the third upper side ends and the second lower side ends of the four working surfaces 12 and are respectively connected to both sides of the upper portion of the workpiece 50 Abutting against the lower surface; wherein, a first vertical positioning block 20 and a second vertical positioning block 30 are used to fix the workpiece 50 on a working surface 12; three horizontal fixing studs 40 are used to prevent the workpiece 50 from shifting in the horizontal and vertical directions; during operation, the workpiece 50 is directly fixed on the positioning device for processing, which is more convenient, and because there are four working surfaces 12, four first vertical positioning blocks 20, four second vertical positioning blocks 30 and twelve horizontal fixing studs 40, four workpieces 50 can be directly processed in one processing, which makes the processing efficiency higher. At the same time, manual operation is less involved, the operation is more standardized, and the occurrence of shape and size deformation during the processing is also reduced.

[0017] When implementing it, Figure 2 As shown, the outer shape of the working surface 12 corresponds to the outer shape of the workpiece 50 .

[0018] When implementing it, Figure 2 As shown, a chip removal hole 13 is opened in the middle of the fixture working surface 12 to discharge the chips generated by the processing of the workpiece 50. During the processing, the workpiece 50 will generate a large amount of chips. If they are not cleaned in time, the chips will accumulate and affect the normal processing of the workpiece 50, which may easily cause damage to the device and processing equipment, and even affect the safety of the operator. Therefore, the chip removal hole 13 is designed to allow the processing chips to be discharged in time to avoid various adverse effects.

[0019] When implementing it, Figure 1 As shown, the four first vertical positioning blocks 20, the four second vertical positioning blocks 30 and the twelve horizontal fixing studs 40 are all detachable.

[0020] When implementing it, Figure 1 As shown, the upper surface of the clamp body 10 is provided with an expansion surface 14. Since the four second vertical positioning blocks 30 are detachable, after the four second vertical positioning blocks 30 are disassembled, a pressure plate is added to the expansion surface 14. The positioning and clamping method of the entire positioning device is changed, and it can be used to process other components, thereby expanding the application scope of the device.

[0021] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
