Description

TECHNICAL FIELD

[0001] The utility model relates to mechanical equipment technical field more particularly, it is a kind of positioning clamping device of groove wheel. BACKGROUND

[0002] In the field of building construction, wall grooving machine is a common power tool, which is mainly used for setting out grooves along the wall to facilitate the layout of pipelines and lines. The existing wall grooving machine is mainly composed of a machine body, a motor, a motor housing, a gear box, a bracket, a switch box, a cutter cover, a gear pair, an output shaft, a cutter and a handle, wherein the cutter is composed of a plurality of wind blade type multi-tooth blades arranged side by side. During construction, the operator holds the handle and operates the wall grooving machine to move along the wall in a predetermined path to set out the required groove. The cutter needs to be positioned before cutting the wall during the cutting process. The existing grooving machine does not have a positioning function, and the worker needs to position it in advance before cutting. As a result, it is time-consuming and labor-intensive. In addition, during cutting, the groove wheel rotates at high speed, so the groove wheel is provided with a tensioning device. The existing tensioning device is not convenient to adjust, which often causes cutting deviation and becomes a problem that needs to be solved during use. In view of this, the present inventors propose a positioning and clamping device for groove wheel, which can adjust the tensioning of the groove wheel by setting an adjusting button on the groove wheel, and can more conveniently position the grooving machine by setting an infrared positioning instrument on the groove wheel frame to achieve precise cutting.

[0003] In order to improve the grooving efficiency of the wall and collect the dust generated during grooving to avoid environmental pollution, Chinese patent (grant announcement number: CN220972903U) discloses a wall grooving machine for building construction, which comprises a machine body, a cutter cover and a cutter. The bottom of the inner wall of the cutter cover is fixedly connected with a left dust collecting box and a right dust collecting box, respectively. The left and right dust collecting boxes are provided with a first slit on one side of the lower edge facing the cutter. The bottom of the inner wall of the cutter cover is fixedly connected with a rear dust collecting box. The rear dust collecting box is connected with the left and right dust collecting boxes and communicates with them. The rear dust collecting box is provided with a second slit on the rear side of the lower edge facing the cutter. One side of the rear dust collecting box is connected with a dust leading-out mechanism. The utility model sets dust collecting boxes corresponding to the left, right and rear sides of the cutter cover in the cutter cover, and connects a dust leading-out mechanism, which can collect dust raised from the left, right and rear sides of the cutter cover in time, thereby effectively preventing dust from escaping and avoiding environmental pollution.
