Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mold detection, in particular to a detection device for cold upsetting mold. BACKGROUND

[0002] The existing file with the publication number CN218937368U discloses a detection device for cold upsetting mold, which comprises a bottom plate, a rotating platform and replaceable vertical supports. The rotating platform is installed on the middle of the upper end surface of the bottom plate. Two replaceable vertical supports are symmetrically installed on the left and right of the middle rear of the upper end surface of the bottom plate. A horizontal support is installed between the upper ends of the two replaceable vertical supports. A horizontal through hole is opened on the front side of the horizontal support. A horizontal screw is rotatably installed in the middle of the horizontal through hole. A translation seat with the rear end inserted into the horizontal through hole is installed on the horizontal screw. An indicating table moving up and down is installed on the front side of the translation seat.

[0003] Under the existing technology, the profile detection of small cold upsetting molds is generally carried out by using a profile instrument. For example, the existing file with the publication number CN109813203A discloses a profile instrument, which comprises a base and a mold seat arranged on the base. The mold seat is used to fix the roller mold. It also comprises a laser probe assembly for contact detection of the mold profile surface. A rotating drive shaft is arranged on the mold seat to drive the roller mold to rotate. The probe assembly is used to maintain contact with the profile surface during the rotation of the mold. The design of the profile instrument improves the traditional measurement degree of freedom control design. The rotating drive shaft is arranged on the mold seat for fixing small roller molds. The rotation is output during measurement. In this process, the probe assembly maintains contact with the surface of the mold. Therefore, the complete profile of the three-dimensional surface of the mold can be measured and recorded by the probe assembly. Moreover, the measurement process does not require disassembly of the roller mold, which ensures the integrity of the surface structure.

[0004] When the detection probe of the above-mentioned profile instrument for mold detection contacts the profile surface of the cylindrical mold, if there are particles or other impurities adhered to the surface of the mold, it will affect the detection work. Especially when using a laser probe for detection work, the adhered impurities are very easy to cause measurement deviation. When the rotating drive mechanism drives the cylindrical mold part to rotate and then realizes the profile measurement work, the connection between the mold and the rotating drive mechanism is either to detect the mold of fixed specifications, or the clamping and fixing mechanism of the rotating drive mechanism is only suitable for molds of the same specifications, which has low work flexibility. Moreover, in the fastening operation, there is a lack of suitable auxiliary components to correct the position of the mold, so as to ensure that the axis of the cylindrical mold and the rotating axis of the driving rotating mechanism are on the same straight line. This not only brings inconvenience to the operator, but also has a certain influence on the detection quality.
