Description

Technical Field

[0001] The utility model relates to the field of assembly auxiliary jigs, and particularly relates to a semi-circular part leveling device. Background Technique

[0002] A semi-circular workpiece is a workpiece with a semi-circular outer diameter cross-section, which can be divided into metal workpieces and non-metal workpieces. The semi-circular workpiece can withstand greater pressure and bending moment and is suitable for rotating assemblies. For some products, various electronic components, induction probes, etc. need to be installed on the semi-circular workpiece in advance. Before assembly, the workpiece needs to be clamped and positioned. However, due to the arc-shaped outer wall of the semi-circular workpiece, it brings difficulties to clamping and positioning. Especially when high precision is required, it is necessary to align the reference and fix it precisely, and the difficulty is even higher. Therefore, it is necessary to make a semi-circular part leveling device to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to provide a semi-circular part leveling device to solve the problems mentioned in the background technique.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A semi-circular part leveling device includes a plurality of leveling jigs arranged in the front-back direction. The leveling jig includes an installation base, a guiding component, a positioning stage component, a supporting column, a leveling pressing plate, an upper locking screw and a lower locking screw. The lower end of the guiding component is fixed on the installation base. The positioning stage component includes a stage base, an elastic component and a placing stage. The stage base is slidably connected with the guiding component. An installation hole is opened at the lower end of the stage base. The elastic component is fixed in the installation hole and its elastic telescopic end contacts the installation base. The lower end of the placing stage is fixed on the upper end of the stage base. A placing groove is provided at the upper end of the placing stage. The bottom of the placing groove is a horizontal plane, and both sides of the placing groove are inclined planes, and the inclined planes are inclined outward from bottom to top. The supporting column is fixed above the installation base through the lower locking screw and corresponds to the left and right sides of the guiding component. The two ends of the leveling pressing plate correspond to the upper ends of the two groups of supporting columns. The upper locking screw passes through the leveling pressing plate and is threadedly connected with the supporting column.

[0006] Further description of the utility model: The elastic component adopts a spring. The spring is placed in the installation hole. The upper end of the spring contacts the upper end of the installation hole, and the lower end of the spring contacts the installation base.

[0007] Further description of the utility model: A guiding groove vertically penetrating the guiding component is provided in the middle of the guiding component. The stage base is slidably connected with the guiding groove.

[0008] Further description of the present utility model: A limiting groove is provided on one side of the stage base, the length direction of the limiting groove is arranged along the vertical direction, a limiting screw is provided on the guiding component, the limiting screw is threadedly connected with the guiding component, and the inner side of the limiting screw corresponds to the inside of the limiting groove.

[0009] Further description of the present utility model: Four groups of leveling jigs are arranged evenly in the front - rear direction.

[0010] The beneficial effects of the present utility model are as follows: At least two groups of leveling jigs are provided, which are respectively used to fix the two ends of the semi - circular arc workpiece. The lower side of the semi - circular arc workpiece is an arc surface, and the upper side is a plane or a partial plane. Before clamping the workpiece, first loosen or completely remove the upper locking screw, place the lower side of the workpiece on the placement stage. The horizontal plane and the inclined plane on the placement stage form three contact positions with the arc surface of the workpiece, so that the center of the workpiece is positioned. At this time, the workpiece can still rotate, so leveling is still required. Then connect the leveling pressing plate to the upper end of the support column through the upper locking screw, and gradually tighten the upper locking screw. The positioning stage assembly descends and the elastic component is compressed. As the elastic pressure of the elastic component becomes greater and greater, the distance between the leveling pressing plate and the placement stage becomes smaller and smaller, so that the workpiece rotates and its upper - side plane fits with the bottom surface of the leveling pressing plate. At this time, the leveling operation of the workpiece is completed, but its height still needs to be positioned. Continue to tighten the upper locking screw until the lower end surface of the leveling pressing plate contacts the upper end surface of the support column. The same operation is performed for each leveling jig, thus completing the leveling and positioning of the semi - circular arc workpiece. The advantage of this design is that it can quickly position and level the semi - circular arc workpiece, and has high positioning accuracy and leveling accuracy. Description of the Drawings

Detailed Description of the Invention

[0016] The present utility model will be further described in conjunction with the accompanying drawings as follows:

[0017] As Figures 1 to 3 shown, a semi-circular part leveling device includes a plurality of leveling fixtures 001 arranged in the front-back direction. The leveling fixture 001 includes a mounting base 01, a guiding component 02, a positioning carrier component 03, a supporting column 04, a leveling pressing plate 05, an upper locking screw 06, and a lower locking screw 07. The lower end of the guiding component 02 is fixed on the mounting base 01. The positioning carrier component 03 includes a carrier base 031, an elastic member 032, and a placing carrier 033. The carrier base 031 is slidably connected to the guiding component 02. The lower end of the carrier base 031 is provided with a mounting hole 0311. The elastic member 032 is fixed in the mounting hole 0311 and its elastic telescopic end contacts the mounting base 01. The lower end of the placing carrier 033 is fixed on the upper end of the carrier base 031. The upper end of the placing carrier 033 is provided with a placing groove. The bottom of the placing groove is a horizontal plane 0331, and both sides of the placing groove are inclined planes 0332. The inclined planes 0332 are inclined outward from bottom to top. The supporting column 04 is fixed above the mounting base 01 through the lower locking screw 07 and corresponds to the left and right sides of the guiding component 02. The two ends of the leveling pressing plate 05 correspond to the upper ends of the two groups of supporting columns 04. The upper locking screw 06 passes through the leveling pressing plate 05 and is threadedly connected to the supporting column 04.

[0018] At least two groups of leveling fixtures 001 are provided, which are respectively used to fix the two ends of the semi-circular workpiece. The lower side of the semi-circular workpiece is an arc surface, and the upper side is a plane or a partial plane. Before clamping the workpiece, first loosen or completely remove the upper locking screw 06, place the lower side of the workpiece on the placing carrier 033. The horizontal plane 0331 and the inclined planes 0332 on the placing carrier 033 form three contact positions with the arc surface of the workpiece, so that the center of the workpiece is positioned. At this time, the workpiece can still rotate, so leveling is still required. Then connect the leveling pressing plate 05 to the upper end of the supporting column 04 through the upper locking screw 06, and gradually tighten the upper locking screw 06. The positioning carrier component 03 descends and the elastic member 032 is compressed. As the elastic pressure of the elastic member 032 becomes greater and greater, the distance between the leveling pressing plate 05 and the placing carrier 033 becomes smaller and smaller, so that the workpiece rotates and its upper side plane fits with the bottom surface of the leveling pressing plate 05. At this time, the leveling operation of the workpiece is completed, but its height still needs to be positioned. Continue to tighten the upper locking screw 06 until the lower end surface of the leveling pressing plate 05 contacts the upper end surface of the supporting column 04. Each leveling fixture 001 adopts the same operation, so as to complete the leveling and positioning of the semi-circular workpiece. The advantage of this design is that it can quickly position and level the semi-circular workpiece, and has high positioning accuracy and leveling accuracy.

[0019] The elastic component 032 is a spring, which is placed in the mounting hole 0311. The upper end of the spring contacts the upper end of the mounting hole 0311, and the lower end of the spring contacts the mounting base 01. The spring has a low cost and is convenient to replace.

[0020] A guiding groove 021 vertically penetrating through the guiding component 02 is provided in the middle of the guiding component 02. The stage base 031 is slidably connected to the guiding groove 021, and the outer contour of the stage base 031 matches the contour of the guiding groove 021, so that the placement stage 033 can be lifted and lowered smoothly.

[0021] A limiting groove 0312 is formed on one side of the stage base 031. The length direction of the limiting groove 0312 is arranged in the vertical direction. A limiting screw 022 is provided on the guiding component 02. The limiting screw 022 is threadedly connected to the guiding component 02, and the inner side of the limiting screw 022 corresponds to the inside of the limiting groove 0312. The limiting screw 022 cooperates with the limiting groove 0312. When no workpiece is installed, the placement stage 033 stops rising a certain distance under the action of the elastic component 032, avoiding the placement stage 033 rising too high, so as to facilitate the placement of the workpiece and the installation of the upper locking screw 06.

[0022] Four groups of leveling jigs 001 are arranged evenly in the front-rear direction, which can fix and level longer workpieces.

[0023] The above does not impose any limitation on the technical scope of the present invention. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
