The utility model relates to the field of machining clamps, in particular to a left box cover assembly machining clamp.
Background
A left box cover assembly of a gearbox is formed by die casting of aluminum alloy, and after die casting, a combination surface and a connecting hole of a product are required to be machined, so that the installation and matching precision of the product is improved. Therefore, a machining clamp is required to be independently designed, the existing machining clamp adopts two taper pins and three positioning bosses to position and clamp, and because the product structure is special, the large-surface machining beat time of the product joint surface is long, and the hidden quality trouble of unstable product machining quality exists, the production development progress and the product quality requirement of a user on the new product can not be met.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides the left box cover assembly machining clamp which is more reasonable in structural design and better in supporting rigidity, and can meet the requirement of large-surface machining of a product joint surface.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the utility model provides a left case lid assembly machine adds anchor clamps which characterized in that: including the anchor clamps bottom plate, two clamp stations that have side by side on the anchor clamps bottom plate, be provided with a set of cylindric lock and a set of taper pin on every clamp station and be used for the left case lid assembly of location, it has a plurality of support columns that support left case lid assembly bottom edge to distribute on every clamp station, and three clamping device distributes on every clamp station, and three clamping device is triangle-shaped and distributes, and every clamping device's compression work below corresponds one the support column, is provided with two on every clamp station and floats the support cylinder at least, two it supports left case lid assembly back of waiting the processing region to float the support cylinder correspondence.
Further, the pressing device is a lever pressing cylinder, and an oil way communicated with the lever pressing cylinder is arranged in the clamp bottom plate.
Further, two bottom plate locating pins are detachably arranged on the clamp bottom plate, and the lower ends of the bottom plate locating pins penetrate out of the bottom surface of the clamp bottom plate.
Further, the four corners of the clamp bottom plate are provided with mounting grooves.
The beneficial effects of the utility model include: the fixture is convenient to position on the machine tool, the fixture adopts two groups of positioning pins to position, the fixture can adapt to a complex back structure, the fixture is provided with the support column and the floating support cylinder, the support strength is improved, the machining of a large product joint surface can be met, the deformation of the product is possibly small, and the machining quality of the product is remarkably improved.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Detailed Description
The utility model will be described in further detail with reference to specific embodiments and drawings.
A left box cover assembly machining clamp shown in figure 1 is used for machining, clamping and fixing a left box cover joint surface of a gear shifting box and all hole sites. The structure of the fixture comprises a fixture bottom plate 1, wherein two parallel clamping stations are arranged on the fixture bottom plate 1, so that two products can be clamped simultaneously for machining, the number of replacement times is reduced, and the machining efficiency is improved. A group of cylindrical pins 2 and a group of taper pins 3 are arranged on each clamping station and used for positioning the left box cover assembly, the group of cylindrical pins 2 are divided into two groups of diagonal distribution along the left box cover assembly respectively, the same number of the group of taper pins 3 is also two, and the adjacent two cylindrical pins 2 are distributed on a group of diagonal angles of the left box cover assembly, so that the left box cover assembly is completely positioned. Each clamping station is provided with a plurality of support columns 4 for supporting the bottom edge of the left box cover assembly, each clamping station is provided with three pressing devices 5, the three pressing devices 5 are distributed in a triangular shape, one support column 4 corresponds to the lower part of a pressing working part of each pressing device 5, the support columns 4 and the pressing devices 5 form a pressing structure to press the left box cover assembly, the pressing devices 5 are lever pressing cylinders, and pressing plates of the lever pressing cylinders press the edge of the left box cover assembly and avoid a joint surface to be added.
Two floating support cylinders 6 are arranged on each clamping station, the left side and the right side of each floating support cylinder 6 correspondingly support the back surface of the left box cover assembly to be processed, the support on the back surface of the left box cover assembly can be well met through the self-adaptability of the floating support cylinders 6, and the support effect cannot be influenced by dimensional errors, so that the machining is that the weak link on the product is not easy to deform.
The compressing device 5 is a lever compressing cylinder and is directly installed and fixed on the clamp bottom plate 1, and an oil way for communicating the lever compressing cylinder is arranged in the clamp bottom plate 1.
In order to realize the quick positioning and mounting of the clamp on the machine tool, two bottom plate positioning pins 7 are detachably arranged on the clamp bottom plate 1, and the lower ends of the bottom plate positioning pins 7 penetrate out of the bottom surface of the clamp bottom plate 1 to be matched and positioned in positioning holes on the machine tool. Four corners of the clamp bottom plate 1 are provided with mounting grooves, and are fixedly connected with a machine tool base through bolts.
The foregoing has described in detail the technical solutions provided by the embodiments of the present utility model, and specific examples have been applied to illustrate the principles and implementations of the embodiments of the present utility model, where the above description of the embodiments is only suitable for helping to understand the principles of the embodiments of the present utility model; meanwhile, as for those skilled in the art, according to the embodiments of the present utility model, there are variations in the specific embodiments and the application scope, and the present description should not be construed as limiting the present utility model.
