Description

Technical Field

[0001] The utility model relates to a vertical bracket for a dial gauge, belonging to the field of dial gauge installation structures. Background Art

[0002] A micrometer is a length measuring instrument that uses gears or levers to convert linear displacement (linear motion) into the rotational motion of a pointer, which is then read on a graduated dial. A micrometer is a widely used indicating measuring tool in precision measurement. It is a comparative measuring instrument that can only measure relative values, not absolute values. It is primarily used to check workpiece shape and positional errors (such as roundness, flatness, perpendicularity, and circular runout), and is also commonly used for precise alignment of workpieces.

[0003] At present, a dial indicator stand is generally used in the use of a dial indicator to reduce measurement errors.

[0004] The Chinese utility model patent application number CN201921366864.X provides a micrometer with a bracket. When adjusting the height of the micrometer, two screws need to be loosened, and then the staff needs to hold the entire micrometer to achieve the lifting and lowering of the micrometer, which is more troublesome to operate.

[0029] Furthermore, the terms "first," "second," "third," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0030] At the same time, in the description of this utility model, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean fixed connection, detachable connection, or integral connection; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0031] See Figure 1-5 This is an embodiment of a vertical bracket for a dial indicator of the utility model.

[0032] It includes two symmetrically arranged vertical plates 1, each vertical plate 1 is provided with a lifting structure 2;

[0033] The lifting structure 2 of the device includes guide grooves 3 arranged on both sides of the vertical plate 1, wherein one guide groove 3 is provided with a roller 4, and the other guide groove 3 is provided with two rollers 4. The rollers 4 are provided with rubber sleeves to provide good friction. The three rollers 4 are connected by their axes to form an isosceles triangle.

[0034] A rotating shaft 5 is provided in the middle of the roller 4, and two ends of the rotating shaft 5 are provided with triangular plates 6, and the rotating shaft 5 is rotatably provided on the triangular plates 6;

[0035] A mounting plate 7 is provided between the triangular plates 6 , and a threaded hole is provided on the mounting plate 7 , in which a pressing screw 8 is threadedly connected, and an operating handle 9 is provided at one end of the pressing screw 8 .

[0036] The dial indicator of this device moves up and down along with the lifting structure 2. In the locked state, the pressing screw 8 is pressed on the groove surface of the guide rail groove 3. At this time, the two rollers 4 on the same side of the pressing screw 8 do not contact the guide rail groove 3, and only the roller 4 on the other side presses on the guide rail groove 3.

[0037] When the lifting structure 2 is being lifted or lowered, the staff can rotate the clamping screw 8 through the operating handle 9. At this time, the clamping screw 8 no longer provides force to the guide rail groove 3. The rubber sleeves on the surfaces of the three rollers 4 will be pressed on the groove surface of the guide rail groove 3. Then the staff only needs to gently move the entire lifting structure 2 to make the lifting structure 2 move up and down, thereby driving the micrometer dial to move up and down, which is very convenient to use.

[0038] When the rollers 4 in this device move in the guide groove 3, they rely on the rotating shaft 5. At the same time, the triangular plate 6 in this device is equivalent to a constraint on the position of the three rollers 4. Without using the tightening screw 8, the three rollers 4 can be clamped on the vertical plate 1.

[0039] An arc plate 10 is also provided between the triangle plates 6 , and a mounting block 11 is provided on the end surface of the arc plate 10 . A transverse guide rod 12 is provided on the mounting block 11 , and a mounting structure 13 is slidably provided on the transverse guide rod 12 , and the micrometer dial is fixed on the mounting structure 13 .

[0040] The micrometer dial in the device can not only be lifted vertically, but also be moved horizontally through the horizontal guide rod 12 and the mounting structure 13, thereby improving the convenience of using the micrometer dial.

[0041] When moving horizontally, the staff can just push the entire installation structure 13;

[0042] The transverse guide rod 12 in the present device is provided with a scale, and the staff can move very conveniently with reference to the scale, so that the subsequent measurement results are more accurate.

[0043] The mounting structure 13 includes a transverse clamping member 14, a vertical clamping member 15, and a mounting member 16 disposed between the transverse clamping member 14 and the vertical clamping member 15. The transverse clamping member 14 includes a first semicircular ring 141, and a first clamping plate 142 is disposed at the end of the first semicircular ring 141. A first clamping gap 143 is formed between the two first clamping plates 142, and the ends of the two first clamping plates 142 are inclined toward the middle.

[0044] The vertical clamping member 15 includes a second semicircular ring 151 , and a second clamping plate 152 is provided at the end of the second semicircular ring 151 . The ends of the two second clamping plates 152 face toward the middle, forming a second clamping gap 153 between the two second clamping plates 152 , and the ends of the two second clamping plates 152 are inclined toward the middle.

[0045] The mounting member 16 is integrally formed with the transverse clamping member 14 and the vertical clamping member 15 , and one side of the mounting member 16 is configured as a plane, on which the micrometer dial is mounted.

[0046] There are two transverse guide rods 12 in this device, and they are arranged one above the other. Therefore, a special mounting structure 13 is designed for the transverse guide rods 12. When in use, first clamp the vertical clamping piece 15 on the transverse guide rod 12 at the bottom, and then push the transverse clamping piece 14 toward the transverse guide rod 12 at the top. At this time, the mounting structure 13 can be installed. The operation is very convenient. After the installation is completed, the staff only needs to push the mounting structure 13 to move the micrometer dial.

[0047] The arrangement of the two transverse guide rods 12, combined with the transverse clamping member 14 and the vertical clamping member 15, can realize the overall constraint of the mounting structure 13, so that the entire mounting structure 13 can slide easily while having the advantage of being very stable, which can increase the accuracy of subsequent micrometer dial measurements.

[0048] The horizontal clamping member 14 and the vertical clamping member 15 in this device have the same structure, except that the first clamping gap 143 in the horizontal clamping member 14 is oriented horizontally, while the second clamping gap 153 in the vertical clamping member 15 is oriented vertically.

[0049] The first semicircular ring 141 on the transverse clamping member 14 and the second semicircular ring 151 on the vertical clamping member 15 are both convenient for sliding in the transverse guide rod 12 .

[0050] A laser transmitter 17 is provided on the end surface of one of the triangular plates 6 , and a laser receiver 18 is provided on the end surface of the other triangular plate 6 .

[0051] The laser emitter 17 in this device is used to emit laser, and the laser receiver 18 is used to receive laser. After adjusting the vertical position of the micrometer, the laser emitter 17 can be turned on to see whether the emitted laser accurately hits the laser receiver 18. If not, it is necessary to adjust the positions of the two lifting structures 2 so that the two lifting structures 2 reach a balanced state.

[0052] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
