Description

Technical Field

[0001] The invention relates to the field of motor measurement, and in particular to a laser positioning tape measure head used for measuring motor dimensions. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy. It can convert the thermal, chemical or electromagnetic effects of electric current into the movement of an object. The core of the motor is the electromagnet, which consists of an iron core and a coil. When electricity is passed through the coil, a magnetic field is generated, which generates a force in the iron core, causing the motor to rotate.

[0003] When installing a motor, you need to first determine the size of the motor, calculate the position of the opening on the carrier based on the size of the motor, and then install the motor using bolts, etc. When existing conventional measuring tools measure the size of a motor, many dimensions are often not in the same plane. For example, the C dimension of the motor, that is, the distance from the shoulder of the motor shaft extension to the axis of the nearest foot bolt hole, is a spatial dimension, which is difficult to measure directly. The commonly used method is to use a straight object with one end attached to the end face of the shaft head and the other end pointing diagonally downward to the foot hole position, and use a tape measure to measure the distance from the foot hole, and then use the measured size to subtract the shaft extension size to calculate the installation size. It is difficult for one person to operate and the error is large, resulting in large errors in the measurement of the installation size.

[0004] Therefore, it is necessary to provide a new laser positioning tape measure head for measuring motor size to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0035] See also Figures 1 to 7 The embodiment of the present invention provides a laser positioning tape measure head for measuring the size of a motor. The laser positioning tape measure head for measuring the size of a motor includes a tape measure body 1, a right-angled steel hook is fixed at the tape measure head in the tape measure body 1, and a positioning device is arranged at the tape measure head through the steel hook;

[0036] The positioning device comprises a mounting seat 2, a locking assembly 6 and a positioning assembly 8 mounted on the mounting seat 2. The mounting seat 2 has a positioning groove 3 at the upper end thereof, and an embedding groove 4 is also provided at the bottom of the positioning groove 3 near the center thereof. The measuring tape head is placed inside the positioning groove 3, and the steel hook on the measuring tape head is inserted into the embedding groove 4.

[0037] The positioning assembly 8 includes a laser generator 89 and an adjustment mechanism. The point irradiated by the light beam of the laser generator 89 is located on the motor, and the irradiated point belongs to the base point. The light beam of the laser generator 89 and the zero scale line in the tape measure body 1 are in the same vertical plane.

[0038] It should be noted that: in the device, the light emitted by the laser generator 89 is irradiated on the motor, and the light is used to replace the traditional wooden board used for positioning. Therefore, when measuring the size of the motor, the process of supporting the wooden board is omitted, and the light beam of the laser generator 89 and the zero scale line in the tape measure body 1 are in the same vertical plane. In this state, the position of the laser generator 89 can be used as the base point for accurate positioning, and it will be more convenient in actual use, and the operation difficulty is low, and it is easy to use;

[0039] When installing the tape measure head, the tape measure is directly pulled out, and the tape measure head is placed in the positioning groove 3, and the steel hook is inserted into the embedded groove 4 to achieve preliminary fixation, and then the tape measure head is squeezed and fixed by the locking component 6 to ensure the stability of the connection between the two. Therefore, the disassembly and assembly process is very convenient, and the tape measure and the positioning device are both small-volume devices, which are also very convenient to carry;

[0040] The laser generator 89 is mounted on the adjustment mechanism, and the irradiation angle of the laser generator 89 can be changed by the adjustment mechanism, so that targeted adjustments can be made according to different measurement positions or distances, ensuring that the point where the laser generator 89 irradiates the motor belongs to the measurement base point, so that its use range will be wider and its practicality will be higher;

[0041] It should be noted that: when taking measurements, it is preferred to adjust the irradiation position of the laser generator 89. After determining the irradiation position, the tape head of the tape measure body 1 is fixed to the mounting base 2. Because when adjusting the irradiation position of the laser generator 89, it may be necessary to adjust the position of the mounting base 2. If the tape measure is fixed in advance, the staff will also need to hold the tape measure body 1, which will have a certain impact on the subsequent point finding.

[0042] In the embodiments of the present invention, please refer to Figure 3 and Figure 5 The locking assembly 6 includes two slides 61 sliding on the inner side wall of the positioning groove 3, and the upper ends of the two slides 61 are fixed with a positioning frame 62 in an inverted U shape and mounted at the notch of the upper end of the positioning groove 3, and a penetrating positioning cylinder 63 is fixed at the center of the upper end of the positioning frame 62. The positioning cylinder 63 is penetrated by a screw rod 64, and the upper end of the screw rod 64 has a first knob 65, and the lower end is rotatably connected to a squeeze disk 66, and the lower end of the squeeze disk 66 is bonded with a rubber pad 67;

[0043] A first slide 5 is further provided on the inner side wall of the positioning groove 3, and a first slide rail 68 is provided on the side of the slide seat 61 for sliding inside the first slide 5. The sliding of the slide seat 61 enables the extrusion plate 66 and the tape measure head to be in a completely corresponding or completely staggered state. When the two are in a completely corresponding state, the tape measure head can be squeezed and fixed by the extrusion plate 66.

[0044] It should be noted that: when the tape measure head is fixed by the locking assembly 6, the screw rod 64 is driven to rotate by the first knob 65, and the screw rod 64 and the positioning cylinder 63 are threadedly connected, so the feeding of the screw rod 64 can drive the extrusion plate 66 to move together until the tape measure head is squeezed and fixed, and in order to prevent the tape measure head from being deformed by the extrusion plate 66, a rubber pad 67 is also provided at the lower end of the extrusion plate 66, so that the tape measure head will not be damaged when the tape measure head is fixed;

[0045] The position of the locking assembly 6 itself is adjustable, because the slide 61 slides inside the positioning groove 3. Its position is manually adjusted so that the squeezing plate 66 can be opposite to or staggered with the tape measure head. In the relative state, the squeezing plate 66 can be used to squeeze the tape measure head to fix the tape measure head; in the staggered state, it is more convenient to place the tape measure head in the positioning groove 3 or take it out of the positioning groove 3.

[0046] In the embodiments of the present invention, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 The upper end of the mounting seat 2 is provided with a first bin 7 near the positioning groove 3. A sealing plate is fixed with screws at the bin opening of the first bin 7, and a through hole is opened on the sealing plate. The adjustment mechanism is installed inside the first bin 7 and extends along the through hole to the top of the first bin 7.

[0047] The adjustment mechanism includes a transmission rod 81 located inside the first bin 7, one end of the transmission rod 81 is extended to the outside of the mounting seat 2, and a second knob 82 is fixed thereto. The transmission rod 81 is also rotatably connected to a support frame 83 fixed to the bottom of the first bin 7, and a coaxial worm 84 is also fixed to the transmission rod 81.

[0048] A support arm 85 is also provided above the transmission rod 81. A worm wheel 86 meshing with the worm 84 is fixed to the lower end of the support arm 85 through a positioning shaft, and the positioning shaft is rotatably connected to the inner wall of the first bin 7. The upper end of the transmission rod 81 is extended to the top of the first bin 7 along the through hole.

[0049] An L-shaped bracket 87 is also fixed to the upper end of the support arm 85, a slot is formed between the bracket 87 and the support arm 85, and a second slideway 88 is vertically arranged on the inner side wall of the slot;

[0050] A socket 810 is also fixed on the outer wall of the circumference of the laser generator 89 , and the laser generator 89 is fixed inside the slot by plugging the socket 810 . The side of the socket 810 also has a second sliding block 811 adapted to the second slideway 88 .

[0051] It should be noted that: the laser generator 89 can be turned on and off by a switch outside the laser generator 89, and the light beam emitted by the laser generator 89 can be used for positioning;

[0052] When the irradiation point of the laser generator 89 is adjusted by using the adjustment mechanism, the transmission rod 81 is driven to rotate by the second knob 82, thereby driving the worm 84 to rotate, and the worm 84 is meshed with the worm wheel 86, thereby driving the worm wheel 86 to rotate, and the worm wheel 86 and the support arm 85 are fixed on the same positioning shaft, and the positioning shaft rotates on the inner wall of the first bin 7, so the positioning shaft can drive the support arm 85 to rotate, and the laser generator 89 is installed at the other end of the support arm 85, so that the laser generator 89 can be driven to rotate together, so as to achieve the adjustment of the irradiation point of the laser generator 89;

[0053] To facilitate the inspection and replacement of the laser generator 89, the socket 810 on the side of the laser generator 89 can be directly plugged into the slot formed between the support arm 85 and the bracket 87, and can be directly pulled out during disassembly. At the same time, the second slide 88 and the second slider 811 can further improve the stability of the laser generator 89.

[0054] In the embodiments of the present invention, please refer to Figure 4 A second compartment 9 is provided at the upper end of the mounting base 2 near the first compartment 7 , and a battery 10 for powering the laser generator 89 is arranged inside the second compartment 9 . An interface for charging the battery 10 is also provided on the side of the mounting base 2 .

[0055] It should be noted that the battery 10 is used to supply power to the laser generator 89 to ensure the normal operation of the laser generator 89 , and can be connected to a charger through an interface to supply power to the battery 10 .

[0056] In the embodiments of the present invention, please refer to Figure 4 A third compartment 11 is provided on one side of the mounting seat 2 near the bottom, and a counterweight 12 is provided inside the third compartment 11 .

[0057] It should be noted that a counterweight block 12 is arranged inside the third compartment 11, which can further increase the weight of the entire mounting base 2. Therefore, when the tape measure head is fixed to the mounting base 2, the stability of the entire mounting base 2 will be higher and less likely to deviate, thereby ensuring the measurement accuracy.

[0058] The specific use process of the device is as follows:

[0059] (1) Positioning;

[0060] First, turn on the laser generator 89, and then adjust the adjustment mechanism according to the position to be measured on the motor or the distance between the mounting seat 2 and the motor. The transmission rod 81 is driven to rotate by the second knob 82, and then the worm 84 is driven to rotate. The worm 84 is meshed with the worm wheel 86, so that the worm wheel 86 can be driven to rotate. The worm wheel 86 and the support arm 85 are fixed on the same positioning shaft, and the positioning shaft rotates on the inner wall of the first bin 7. Therefore, the support arm 85 can be driven to rotate through the positioning shaft, and the laser generator 89 is installed at the other end of the support arm 85, so that the laser generator 89 can be driven to rotate together, so as to adjust the irradiation point of the laser generator 89, so that the irradiation position of the laser generator 89 is at the base point of the measurement position to ensure the accuracy of positioning;

[0061] (2) Fixing the tape measure head;

[0062] When installing the tape measure head, directly pull out the tape measure, place the tape measure head in the positioning groove 3, and insert the steel hook into the embedded groove 4 to achieve preliminary fixation;

[0063] When the tape measure head is fixed by the locking assembly 6, the screw 64 is driven to rotate by the first knob 65, and the screw 64 and the positioning cylinder 63 are threadedly connected, so the feeding of the screw 64 can drive the extrusion plate 66 to move together until the tape measure head is squeezed and fixed;

[0064] (3) Measurement;

[0065] Continue to pull out the tape measure until the extended length is equal to or greater than the size of the location being measured, then calibrate it to know the exact size of the area being measured.

[0066] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
