Description

Technical Field

[0001] The utility model relates to the technical field of hardware precision processing, in particular to a concentricity testing tool for welding copper sheets. Background Art

[0002] Welding copper sheet is a welding material, usually used to connect copper and copper alloys. Welding copper sheet is mainly composed of metals such as copper, nickel and zinc. It has good conductivity, plasticity and corrosion resistance. Welding copper sheet is widely used in the manufacture of household appliances, electronic equipment, auto parts, architectural decoration and other fields. Welding copper sheet can also be used to make handicrafts and decorations. There are many shapes of welding copper sheet, among which welding copper sheet with two round holes in the middle is particularly common.

[0003] In order to ensure the accuracy of welding copper sheets, it is necessary to test the concentricity of the two circular holes and the flatness of the welding sheets, and a concentricity testing tool for welding copper sheets is needed. The existing welding copper sheets are mostly tested for concentricity and flatness manually, with the needle of a dial indicator touching the inner wall of the circular hole and the surface of the copper sheet, and the various data of the welding copper sheet are judged by observing the dial indicator readings. In the traditional concentricity and flatness test of welding copper sheets, since the welding copper sheets are special-shaped parts with different sizes, the center of the circular hole on the copper sheet cannot be quickly determined, the manual test has a large error, and the concentricity and flatness tests cannot be taken into account at the same time. The test efficiency of welding copper sheets is low. Therefore, a concentricity testing tool for welding copper sheets is proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a concentricity testing tool for welding copper sheets, which can quickly determine the center position of circular holes on welding copper sheets of different sizes, automatically test with high test accuracy, and can also take into account the tests of concentricity and flatness at the same time, thereby improving the test efficiency of welding copper sheets and effectively solving the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concentricity test tool for welding copper sheets, comprising a base and a rapid testing mechanism;

[0006] The rear end of the base is slidably connected to a moving seat, the inner upper end of the moving seat is rotatably connected to a connecting shaft, and the front end of the connecting shaft is provided with a mounting plate;

[0007] The quick testing mechanism includes a sliding column, a fixed block, a pressure plate, a tension spring and a screw rod. The sliding columns are all arranged at the front end of the mounting plate. A fixed block is provided at the front end of two vertically adjacent sliding columns. The pressure plates are slidably connected between the two vertically adjacent sliding columns. A tension spring is provided between the rear end of the fixed block and the front end of the pressure plate. The tension spring is sleeved on the outer surface of the sliding column. The screw rod is threadedly connected to the middle of the inner part of the fixed block. The rear end of the screw rod is fitted with the front end of the longitudinally adjacent pressure plate. The front end of the screw rod is provided with a knob, which can quickly fix and release the welding copper sheet.

[0008] Furthermore, the rapid testing mechanism also includes a positionable rotating component, which includes a limit block and an electric push rod. The limit block is slidably connected to the middle of the inner front side of the fixed block, and the electric push rod is arranged on the inner rear side of the fixed block. The input end of the electric push rod is electrically connected to the output end of the single-chip microcomputer, and the front end of the telescopic end of the electric push rod is fixedly connected to the rear end of the limit block, so as to quickly locate the center position of the circular hole on the welding copper sheet.

[0009] Furthermore, the positionable rotating component also includes a motor and gears. An end cover is provided on the rear side of the upper end of the movable seat. The motor is arranged inside the end cover. The input end of the motor is electrically connected to the output end of the single-chip microcomputer. The gears are respectively arranged at the rear ends of the connecting shaft and the output shaft of the motor. The two gears are meshed and connected and rotate automatically, which is convenient for testing the concentricity of the circular holes on the welding copper sheet.

[0010] Furthermore, the rapid testing mechanism also includes a moving component, which includes a guide column and a screw rod. The guide columns are arranged between the left and right inner walls of the base. The outer surface of the guide column is slidingly connected to the inner middle of the moving seat. The screw rod is rotatably connected to the upper rear side of the base. The outer surface of the screw rod is threadedly connected to the inner center of the moving seat, providing a basis for testing the flatness of the welded copper sheet.

[0011] Furthermore, the moving component also includes a handwheel, which is arranged at the right end of the screw rod. The outer surface of the handwheel is provided with evenly distributed anti-slip stripes, which can quickly drive the moving seat to move left and right to achieve flatness testing.

[0012] Furthermore, the rapid testing mechanism also includes a universal bracket and a dial indicator. The universal bracket is arranged at the middle of the upper front side of the base, and the dial indicator is arranged at the upper rear side of the universal bracket.

[0013] Furthermore, the single chip microcomputer is arranged at the right rear end of the base, and the input end of the single chip microcomputer is electrically connected to an external power supply to provide a control effect for the test of welding copper sheets.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. Turn the knob, and the screw will rotate accordingly. As the knob turns, the screw moves down and continuously presses the pressure plate, causing the pressure plate to move down synchronously. The tension spring is expanded under force until the pressure plate lightly contacts the surface of the welding copper sheet. At this time, the pressure plate forms a preliminary fixation on the welding copper sheet, and the fixing effect is not high. At this time, if the pressure plate is subjected to force, it will move longitudinally. Due to the limitation of the pressure plate, no vertical displacement will occur. The single-chip microcomputer controls the electric push rod to work, and the telescopic end of the electric push rod extends forward, driving the limit block to move forward until the outer edge of the limit block contacts the inner wall of the circular hole on the welding copper sheet. At this time, as the limit block moves forward, the welding copper sheet moves, causing the inner wall of the circular hole to be close to the outer edge of the limit block. At this time, the position of the circular hole on the welding copper sheet coincides with the center of the circle of the limit block and the connecting shaft, and the center position is determined. Then turn the knob again to make the pressure plate and the welding copper sheet contact more closely, and the fixing effect is maximized. The center position of the circular hole on welding copper sheets of different sizes can be quickly determined.

[0016] 2. Adjust the universal bracket so that the probe of the dial indicator contacts the inner wall of the circular hole. The single-chip computer controls the operation of the motor. The output shaft of the motor drives the gear below to rotate, and the connecting shaft also rotates synchronously, driving the mounting plate and the welding copper sheet to rotate. As the welding copper sheet rotates, the probe of the dial indicator contacts the inner wall of the circular hole to obtain a reading, and the concentricity data of the circular hole on the welding copper sheet can be obtained. When it is necessary to test the flatness of the welding copper sheet, adjust the universal bracket so that the probe of the dial indicator contacts the surface of the welding copper sheet, turn the handwheel, and the screw rod also rotates synchronously, driving the moving assembly to move longitudinally along the guide column. At this time, the probe of the dial indicator contacts the surface of the welding copper sheet to obtain a reading, and the flatness data of the welding copper sheet can be obtained. Automatic testing has high testing accuracy and can also take into account the testing of concentricity and flatness at the same time, thereby improving the testing efficiency of the welding copper sheet.

The test is automatic with high test accuracy, and can also take into account the concentricity and flatness tests at the same time, thereby improving the test efficiency of the welding copper sheet.

[0026] The working principle of the utility model is as follows:

[0027] When testing the concentricity of the welding copper sheet, first locate the center position of the circular hole on the welding copper sheet, stick the welding copper sheet to the front end of the mounting plate 4, align the circular hole to be tested with the limit block 561, and then turn the knob, and the screw 55 will rotate accordingly. Because the screw 55 is threadedly connected to the middle of the inner part of the fixing block 52, the rear end of the screw 55 is in contact with the front end of the longitudinally adjacent pressing piece 53. Therefore, as the knob is turned, the screw 55 moves downward and continuously presses the pressing piece 53, so that the pressing piece 53 moves downward synchronously, and the tension spring 54 is expanded by force until the pressing piece 53 lightly contacts the surface of the welding copper sheet. At this time, the pressing piece 53 forms a preliminary fixation on the welding copper sheet, and the fixing effect is not high. At this time, if the pressing piece 53 is subjected to force, it will move longitudinally, but due to the limitation of the pressing piece 53, no vertical displacement will occur.

[0028] The single chip computer 6 controls the electric push rod 562 to work, and the telescopic end of the electric push rod 562 extends forward, driving the limit block 561 to move forward until the outer edge of the limit block 561 contacts the inner wall of the circular hole on the welding copper sheet. At this time, as the limit block 561 moves forward, the welding copper sheet is displaced, so that the inner wall of the circular hole is close to the outer edge of the limit block 561. At this time, the position of the circular hole on the welding copper sheet coincides with the center of the circle of the limit block 561 and the connecting shaft 3, and the center position is determined. Then, the knob is turned again to make the pressing sheet 53 and the welding copper sheet contact more closely, and the fixing effect is maximized. The universal bracket 58 is adjusted to make the measuring needle of the dial indicator 59 contact the inner wall of the circular hole.

[0029] The single chip computer 6 controls the operation of the motor 563, and the output shaft of the motor 563 drives the gear 564 below to rotate. Because the two gears 564 are meshed and connected, the connecting shaft 3 also rotates synchronously, driving the mounting plate 4 and the welding copper sheet to rotate. As the welding copper sheet rotates, the probe of the dial indicator 59 contacts the inner wall of the circular hole to obtain a reading, and the concentricity data of the circular hole on the welding copper sheet can be obtained. When it is necessary to test the flatness of the welding copper sheet, adjust the universal bracket 58 so that the probe of the dial indicator 59 contacts the surface of the welding copper sheet, turn the hand wheel 573, and the screw rod 572 also rotates synchronously, driving the moving assembly 57 to move longitudinally along the guide column 571. At this time, the probe of the dial indicator 59 contacts the surface of the welding copper sheet to obtain a reading, and the flatness data of the welding copper sheet can be obtained. The center position of the circular hole on the welding copper sheet of different sizes can be quickly determined, and the automatic test has high test accuracy. It can also take into account the tests of concentricity and flatness at the same time, thereby improving the test efficiency of the welding copper sheet.
