Description
Technical Field
The invention relates to a clamp, in particular to a clamp for correcting a processing position of a die module, which can accurately and quickly position a surface to be processed on the die module.
Background
At the present that the demand of automobile wheel hubs is increasing continuously, wheel hub manufacturers continuously require shortening the delivery period of wheel hub moulds. This places very high demands on the hub mould manufacturer. In order to meet the requirement, a hub die manufacturer wants to improve the production efficiency of each link in die production by all methods. Through long-term research by the inventor, it is found that one of the processing links of the hub side module is considered seriously. The existing low-pressure casting hub die comprises an upper die, a lower die and a side die, wherein the side die generally comprises a plurality of hub side modules, and all hub side modules are spliced together to form an annular side die. In order to facilitate heat dissipation and reduce material consumption, a back cavity needs to be machined on the back side of each hub-side module. During the machining process, the hub-side module is first calibrated in the milling machine, for which purpose side-form clamps are generally provided. In order to avoid shielding the back side surface (the back side surface is the surface to be processed) of the hub side module, it is currently conventional to perform calibration positioning on the left and right side surfaces and the front side surface of the hub side module. However, since the hub-side module itself has a manufacturing error, when the hub-side module is corrected and positioned with reference to the left and right side surfaces and the front side surface of the hub-side module, the back side surface of the hub-side module is necessarily deviated from the correct machining reference position, which results in inaccurate machining.

According to the technical scheme, the second correcting working surface is fixed, and the first correcting working surface can be used for assisting the first correcting working surface in correcting the machining position of the die module in specific application.
In order to fix the processing position of the die module, the further technical scheme may further include a vertical column disposed on the bottom plate and a top pressing block disposed on the vertical column in a manner of moving up and down, wherein the top pressing block is used for pressing and fixing the die module.
In order to adapt to the mold modules with different dimensions, a further technical scheme can be that the vertical columns are arranged on the bottom plate in a sliding mode. This allows the position of the vertical posts to be flexibly adjusted to the size of the mould module.
In order to enable the fixture to fix four mold modules simultaneously, a further technical scheme may be that the bottom plate is square so as to have four bottom plate edges perpendicular to each other, and four vertical columns are further configured, and each vertical column is arranged corresponding to one bottom plate edge and offset to one side of the bottom plate edge. According to the technical scheme, two die modules which are vertically arranged can be arranged at the position corresponding to each bottom plate edge, and each die module can be pressed and fixed by the pressing blocks on the adjacent vertical columns. So four mould modules can be fixed simultaneously to anchor clamps, are favorable to improving mould module's machining efficiency.
