Roller contour projector

Abstract

The invention discloses a roller contour projector which comprises a bottom plate, a lifting device, a measuring platform, a fastening device, positioning columns, a light source projection device anda projection bearing device. The measuring platform is connected with the lifting device; the lifting device is used for adjusting the distance between the measuring platform and the bottom plate; the number of the positioning columns is three, and the positioning columns are arranged in the vertical direction and penetrate through the measuring platform and are connected with the fastening device. The fastening device is used for adjusting the positioning columns to enable the positioning columns to move horizontally; the light source projection device is used for projecting light sources towards the measuring platform; and the projection bearing device is used for bearing the projection projected to the measuring platform by the light source projection device. According to the invention, a to-be-tested piece is clamped and fixed in a three-point positioning type stand column clamping manner; measurement can be completed through direct projection after the position of the to-be-measured piece is adjusted through the fastening device and the lifting device, positioning, adjustment and detection of the roller or a pressing head are simply and rapidly achieved, the abrasion condition of the roller or the pressing head can be judged, operation is convenient, measurement precision is high, and efficiency is high.

Description

technical field [0001] The invention relates to the technical field of precision parts detection, and more specifically relates to a roller profile projector. Background technique [0002] Roller and pressure head are mechanical spare parts that must be used on can sealing machinery and equipment. They are used to evenly seal the bottom or lid of three-piece cans and two-piece cans on the can body to achieve the final use purpose. It is the can body An important part that is rolled up with the can lid. The size of the roller and pressure head is selected according to the diameter of the can, and the specification parameters should be standardized, and the size cannot be changed arbitrarily, so as to ensure the standard of the inner diameter of the can and the can lid. For example, if the pressure head is too large, the empty cans will not fall easily after sealing; if the pressure head is too small, it will cause defects such as friction and slippage of the can lid, which w...

Problems solved by technology

[0003] However, although this replacement method can avoid the impact of wear on the production of the rollers and indenters to a certain extent, there are usually situations where the rollers and indenters do not meet the scrap standard, that is, they are abandoned in a repairable state. Due to the high cost of rollers and indenters, it causes great waste; at the same time, there are also cases where rollers and indenters are not replaced in time, which has a bad impact on production quality and production progress.
