Description

Technical Field

[0001] The utility model belongs to the field of pipe grinding devices, in particular to a device for leveling linear welds of round pipes. Background Art

[0002] Before use, round tubes need to be connected and fixed by welding, and there will usually be protruding parts on the outside of the round tubes after welding. In order to ensure the normal use of the round tubes, the protruding parts on the outer ends of the tubes need to be ground flat by a grinding device before assembly to make them meet the use requirements. However, there are some shortcomings in the existing round tube weld grinding devices. First, the grinding device lacks a structure to assist in detecting the grinding quality of the round tubes. After the leveling process is completed, it is impossible to determine whether the round tube meets the processing requirements, and it needs to be disassembled and measured. Secondly, after the grinding device has installed the round tube, it is impossible to detect whether the round tube is parallel to the grinding roller. Once tilted, it will affect the accuracy of the leveling process. Summary of the Invention

[0003] In view of this, the utility model aims to propose a leveling device for linear welds of round tubes to solve the problem that it is impossible to judge whether the round tubes are qualified after grinding and it is impossible to detect whether the installation of the round tubes meets the processing requirements.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:

[0005] The device for leveling the linear weld of a circular tube includes a base plate, a fixed frame is provided at the left end of the rear side of the base plate, and the connecting plate at the outer end of the fixed frame is plugged into and matched with the rectangular groove in the base plate; a movable frame is plugged into the left end of the base plate, and the movable frame is plugged into and matched with the slot in the base plate, and the side rod at the outer end of the movable frame is plugged into and matched with the guide groove in the slot.

[0006] Furthermore, the base plate is a rectangular structure, and a rectangular groove is opened at the left end of the rear side of the base plate, and an adjustment groove is opened inside the base plate; the adjustment groove is opened on the right side inside the base plate, and a screw is rotatably installed inside the adjustment groove.

[0007] Furthermore, a slot is provided in the base plate; the slot is provided inside the left side of the base plate, and a guide groove is provided in the slot; the guide grooves are symmetrically provided on both sides of the slot.

[0008] Furthermore, a movable plate is provided on the adjustment slot; the movable plate is slidably installed on the upper end of the adjustment slot, and the movable plate is threadedly connected to the screw in the adjustment slot, and a chuck is installed on the movable plate; the chuck is rotatably installed on the outside of the movable plate, and the chuck is connected to a motor.

[0009] Furthermore, a screw is rotatably installed inside the fixing frame, and a connecting plate is provided on the fixing frame; the connecting plate is provided at the lower end of the front side of the fixing frame.

[0010] Furthermore, a lifting frame is slidably installed on the fixed frame; a grinding roller connected to a motor is rotatably installed at the front end of the lifting frame, and the lifting frame is threadedly connected to the screw in the fixed frame, and a slide groove is provided inside the lifting frame; the slide groove is vertically symmetrically opened on both sides of the interior of the lifting frame.

[0011] Furthermore, a base rod is slidably installed on the slide groove; both sides of the base rod extend from the slide groove, and scale grooves are opened on both sides of the outside of the base rod, a rectangular groove is opened at the bottom side end of the base rod, and a pressure plate is provided at the lower end of the base rod; the pressure plate is rotatably installed in the rectangular groove at the lower end of the base rod.

[0012] Furthermore, a rectangular through slot is provided inside the movable frame, and side rods are provided at the outer ends of the movable frame; the side rods are symmetrically arranged on both sides of the outer portion of the movable frame.

[0013] Furthermore, a pull rod is slidably installed in the movable frame; the round rod at the left end of the pull rod passes through the movable frame, and a telescopic rod is movably installed in the pull rod; the telescopic rod is vertically slidably installed on the pull rod through an elastic member.

[0014] Compared with the prior art, the device for leveling the linear weld of a circular tube described in the present invention has the following beneficial effects:

[0015] (1) This application slides the base rod in the slide groove in the lifting frame, and sets scale grooves at both ends of the base rod, and rotates the pressure plate to be installed in the rectangular groove at the lower end of the base rod, so that the pressure plate can be flipped at the bottom of the base rod. When in use, the pressure plate is flipped to the front end of the base rod, and then the lifting frame is moved downward until the pressure plate is overlapped on the round tube, and the base rod is pushed out from the upper end of the slide groove. By observing the height of the base rods on both sides extending from the slide groove, it is judged whether the round tube is tilted, thereby ensuring that the installation of the round tube meets the installation requirements of the leveling process.

[0016] (2) The present application inserts a movable frame into a slot, slides a pull-out rod in the movable frame, and slides the Y-shaped telescopic rod onto the pull-out rod through an elastic member. When the round tube is leveled, the Y-shaped telescopic rod is pressed against the bottom edge of the round tube, and then the pull-out rod is pushed, so that the pull-out rod drives the telescopic rod to slide along the bottom side of the round tube. If no protruding part is encountered during the sliding process and the tube moves all the way to the other end, it proves that the leveling quality of the round tube is good. If an obstruction is encountered during the sliding process, it proves that the leveling process of the round tube is not perfect. This makes it convenient for staff to quickly detect the leveling quality of the round tube. BRIEF DESCRIPTION OF THE DRAWINGS
