Description

Tensioning and positioning device for turbocharger housing

technical field

The utility model relates to a process equipment, in particular to a tensioning and positioning device for a casing of a turbocharger.

Background technique

For special-shaped workpieces such as turbocharger shells, when they are processed on the machining center, they are usually compressed by moving the pressure plate, which is cumbersome to operate. It takes a lot of time to adjust the positioning and compress the workpiece each time. Due to the long processing preparation time, the production efficiency is reduced, and due to the poor uniformity of the clamping, the positioning accuracy is difficult to guarantee, which also affects the processing accuracy to a certain extent. In addition, some workpieces also have the problem of being difficult to find a suitable pressing point, which brings inconvenience to the processing.

Utility model content

Aiming at the above problems, the applicant made research and improvement, and provided a tensioning and positioning device for the turbocharger housing, which has a simple and compact structure, convenient and fast operation, can quickly position and compress workpieces, has high repeat positioning accuracy, and improves production. Efficiency, to ensure the processing accuracy of the product.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A tensioning and positioning device for a turbocharger housing, comprising a base plate, a base, a jacket and a pull rod, a heightening pad is provided under the base plate, the jacket includes a positioning part and an expansion sleeve part, and the base The jacket is positioned and pressed on the bottom plate through the positioning part of the jacket; the expansion part of the jacket is cylindrical, and the jacket is provided with an inner tapered hole and at least three symmetrically arranged radial through groove; the tie rod includes a truncated cone part and a screw part, the truncated cone part of the tie rod is in the shape of an inverted truncated cone and cooperates with the inner taper hole of the expansion sleeve part of the jacket, and the screw part of the tie rod is set It has an external thread and passes through the jacket and the bottom plate, and the nut is threadedly connected to the screw part of the pull rod and pressed against the bottom surface of the bottom plate.

further:

The nut is a shoulder nut.

The technical effect of the utility model is:

The utility model discloses a tensioning and positioning device for a turbocharger housing, which has a simple and compact structure, adopts a structure in which a jacket and a pull rod are matched, is convenient and quick to operate, can quickly position and compress a workpiece, has high repeat positioning accuracy, and improves Production efficiency, to ensure the processing accuracy of the product.

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.

As shown in Figures 1, 2, and 3, the utility model includes a base plate 6, a base 4, a jacket 5 and a pull rod 1. There are 4 heightening pads 3 under the base plate 6, and the jacket 5 includes a positioning part 502 and an expansion sleeve. part 501, the base 4 positions and presses the jacket 5 on the bottom plate 6 through the positioning part 502 of the jacket 5, the expanding part 501 of the jacket 5 is cylindrical, and the expanding part 501 is provided with inner tapered holes 504 and 4 There are three radial through-slots 503 arranged symmetrically, and the number of through-slots 503 can be determined according to actual needs. Usually, at least three radial through-slots 503 need to be arranged symmetrically. The tie rod 1 includes a truncated cone part 101 and a screw part 102. The truncated cone part 101 of the tie rod 1 is in the shape of an inverted truncated cone. The screw part 102 of the pull rod 1 is provided with external threads, the screw part 102 of the tie rod 1 passes through the jacket 5 and the bottom plate 6, the nut 2 is threadedly connected to the screw part 102 of the pull rod 1 and pressed against the bottom surface of the bottom plate 6, in this embodiment, Nut 2 is a shoulder nut, which can play the role of anti-loosening.

In actual use, the utility model is placed on the workbench of the machining center, and is positioned and pressed with a moving platen; the nut 2 is loosened, and the hole at the bottom of the turbocharger housing 7 is placed on the expansion sleeve part 501 of the jacket 5 Above, the bottom surface of the turbocharger housing 7 is attached to the top surface of the base 4, and the nut 2 is tightened, the frustum part 101 of the tie rod 1 moves downward, and the expansion sleeve between the frustum part 101 of the tie rod 1 and the jacket 5 Under the cooperation of the inner tapered hole 504 of the jacket part 501, the expansion sleeve part 501 of the jacket 5 expands outwards and tightens in the hole at the lower part of the turbocharger housing 7, so that the turbocharger housing 7 is positioned Press tight. When using it for the first time, adjust and position the tightening and positioning device of the present utility model. After each processing, loosen the nut 2 to take out the processed workpiece conveniently, and then position and compress according to the above operation steps. The workpiece to be processed is convenient and quick to operate, which improves production efficiency and ensures processing accuracy.
