Description

Technical Field

[0001] This invention belongs to the field of motor housing size measurement technology, specifically a laser measurement device and method for motor housing size. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. During processing and installation, the dimensions of the motor housing need to be inspected. Previously, the dimensions of the motor housing were generally measured by workers using measuring tools such as rulers. With continuous equipment improvements, laser measuring equipment, such as laser profile measuring instruments, is now commonly used. These instruments operate on the principle of triangular reflection or white light interference, irradiating a strip of laser light onto the surface of the target object. By receiving changes in the reflected light, they measure contours such as height, height difference, and width in a non-contact manner. Then, by processing the continuously acquired contour data, they obtain the 3D shape of the target object. This method is suitable for surface contour inspection, dimensional measurement, and appearance inspection of motor housings. However, during measurement, the motor housing generally needs to be clamped and fixed to ensure measurement accuracy. But this method has the following drawbacks:

[0003] Because the motor housing has a multi-faceted structure, if the motor housing and the clamping component are rotated together during the clamping process, the clamping component may move above the motor housing, thus obstructing the laser scanning. If the motor housing is disassembled, rotated, and then reinstalled for measurement, the disassembly and assembly are troublesome and the measurement efficiency is low. Summary of the Invention

[0006] The motor clamping assembly includes two annular frames symmetrically arranged above the base. The annular frames are fixedly installed on the base. A toothed ring is rotatably installed on the inner side of the annular frame. A connecting ring is provided on the inner side of the toothed ring. Four side boxes are installed at equal angles between the connecting ring and the toothed ring. An internal block is movably installed inside the side box.

[0012] As a further optimization, the exhaust control assembly includes two contacts mounted on the internal block, which are electrically connected.

[0013] As a further optimization, the first contact block is composed of a conductive substrate electrically connected to the first contact base and two elastic contact pieces, forming a U-shape.

[0014] As a further optimization, the disconnecting power-off component includes a fixed box disposed on the side of the first contact block away from the contact point. The fixed box is fixedly installed on the side box. A guide groove is opened on the side of the fixed box near the first contact block. Two push arms are symmetrically slidably installed on the inner side of the guide groove. The two push arms are located between two elastic contact plates. A sliding plate is slidably installed inside the fixed box. Two first connecting rods are symmetrically hinged on the side of the sliding plate near the guide groove. The ends of the two first connecting rods are respectively hinged to the two push arms. A rod groove is opened on one side of the fixed box. The opening surface of the rod groove is perpendicular to the opening surface of the guide groove. A movable rod is movably installed inside the rod groove. A connecting block is installed at one end of the movable rod. A second connecting rod is hinged on one side of the connecting block. The other end of the second connecting rod is hinged to the sliding plate. A second spring is installed on the side of the connecting block near the movable rod. One end of the second spring is fixedly connected to the inner wall of the fixed box. A counterweight is installed at the other end of the movable rod.

[0015] As a further optimization, the intake control assembly includes an inner cavity opened inside the pressure head. Second electrical blocks are symmetrically installed on both sides of the inner wall of the inner cavity, and second electrical sockets are symmetrically installed on the outer wall of the pressure head. The second electrical blocks and second electrical sockets are electrically connected. An insulating plate is movably installed inside the inner cavity, and a conductive strip is installed on the insulating plate. The conductive strip is located on the side of the second electrical block near the side box. A push rod is symmetrically installed on the side of the insulating plate near the side box, with one end of the push rod penetrating to the side of the pressure head near the side box. A third spring is symmetrically installed on the side of the insulating plate near the side box, with one end of the third spring fixedly connected to the inner wall of the end of the inner cavity.

[0016] As a further optimization, the laser measurement position adjustment assembly includes a rotating platform fixedly installed on the top of the base, a rotating mounting frame rotatably installed on the inner side of the rotating platform, a rotation drive mechanism for driving the rotating mounting frame to rotate on the rotating platform, a lateral movement mechanism installed on the top of the rotating mounting frame, a side movement mechanism installed on the lateral movement mechanism, and a laser measuring instrument installed on the side movement mechanism.

[0017] As a further optimization, a measurement method for a laser measuring device for motor housing dimensions is provided, the measurement method being as follows:

[0018] S1. Installation: Install the motor between the two connecting rings, drive the two extrusion parts to move closer to each other, drive the side box outside the upper side box to work, move the mounting plate to the position corresponding to the motor, and the clamping parts perform clamping work.

[0019] S2, Circumferential Measurement: The upper surface is measured by laser measurement using a laser measuring instrument. Then, the connecting ring rotates, driving the motor to rotate. The upper surface of the motor housing is measured by laser measurement using the laser measuring instrument.

[0020] S3. End Measurement: The rotating drive mechanism drives the rotating mounting bracket to rotate, so that the laser measuring instrument rotates sequentially to the position corresponding to the two connecting rings, and passes through the connecting rings to perform laser measurement of the dimensions of both ends of the motor housing.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1) During operation, the motor is installed between two connecting rings. When the laser measuring instrument is above the motor, the motor rotates and the circumferential surface of the motor housing is measured by laser. When the rotating mounting bracket rotates, the laser measuring instrument passes through the two connecting rings and can measure the dimensions of both ends of the motor housing by laser, thus improving the convenience of laser measurement.

[0023] 2) During operation, the pressure heads corresponding to the three side boxes at the bottom contact the C-shaped plates on the extrusion parts, so that the three side surfaces of the motor housing, except for the top wall, coincide with the corresponding mounting plate positions. This allows the other three sides to be clamped by the clamping parts, and there are no obstructions above the motor housing. This facilitates the laser measuring instrument to perform laser measurement on the upper surface of the motor housing. The side box that was originally located at the top can be directly clamped after rotating downwards, improving the stability of the motor's dimensional measurement.

[0024] 3) During operation, when the pressure head is subjected to the pressure of the C-shaped plate, the contact point contacts the first electrical block, and the second electrical block contacts the conductive strip, which connects the circuits of the first and second solenoid valves, causing the clamping parts to perform clamping work. When the side box rotates to the position corresponding to the empty slot, the corresponding cylinder exhausts air, which facilitates the relocation of the mounting plate.

[0025] 4) During operation, when the side box is rotated to the top position, the counterweight is in a vertical downward state, which makes it overcome the resistance and move downward, thereby pushing the two push arms away from each other. The two push arms are located between the two elastic contact plates of the first contact block, so that the two elastic contact plates open and separate from the contacts, which facilitates the venting of the clamping parts before the mounting plate moves back, and avoids the impact of the mounting plate moving back on the motor.

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Depend on Figure 1-10 The present invention relates to a laser measuring device for motor housing dimensions, comprising a base 1 and a laser measuring instrument 205 for laser measuring the dimensions of the motor housing, characterized in that: a motor clamping assembly 3 is provided at the top of the base 1 for clamping the motor, and a laser measuring position adjustment assembly 2 for driving the laser measuring instrument 205 to adjust its position is also installed on the base 1.

[0041] The motor clamping assembly 3 includes two annular frames 301 symmetrically arranged above the base 1. The annular frames 301 are fixedly installed on the base 1. A toothed ring 304 is rotatably mounted on the inner side of the annular frame 301. A connecting ring 305 is provided on the inner side of the toothed ring 304. Four side boxes 306 are installed at equal angles between the connecting ring 305 and the toothed ring 304. An internal block 307 is movably installed inside the side box 306. A first connecting rod 308 is symmetrically installed on the side of the internal block 307 near the connecting ring 305. A mounting plate 309 is fixedly installed on the end of the first connecting rod 308. A clamping member 310 is installed on the mounting plate 309. The other side of the internal block 307... A second connecting rod 312 is installed, and a pressure head 313 is installed at one end of the second connecting rod 312. A pressing member 314 is provided on the side of the pressure head 313 away from the connecting ring 305. The pressing member 314 is used to generate pressure on each pressure head 313 except for the upper pressure head 313. The motor is installed between the two connecting rings 305. When the laser measuring instrument 205 is above the motor, the motor rotates and performs dimensional laser measurement on the circumferential surface of the motor housing. When the rotating mounting bracket 202 rotates, the laser measuring instrument 205 passes through the two connecting rings 305, which can realize the dimensional laser measurement of both ends of the motor housing, improving the convenience of laser measurement.

[0042] The end of the pressure head 313 is hemispherical. A first spring 311 is fixedly installed on the side of the internal block 307 near the mounting plate 309. One end of the first spring 311 is fixedly connected to the inner wall of the end of the side box 306. An exhaust control component 4 is installed inside the side box 306. An intake control component 5 is installed inside the pressure head 313. A connecting groove is opened on one side of the ring frame 301. A gear 302 is installed inside the connecting groove. The gear 302 meshes with a gear ring 304. The gear ring 304 is fixedly connected to the output shaft of the drive motor 303. The drive motor 303 is fixedly installed on the motor mounting bracket. The motor mounting bracket is fixedly installed on the ring frame 301.

[0043] The extrusion member 314 includes a C-shaped plate 3141 disposed on the side of the pressure head 313 away from the connecting ring 305. A slot 3143 is provided at the center of the top of the C-shaped plate 3141, the position of which corresponds to the uppermost pressure head 313 among the four pressure heads 313. Bending portions 3142 are provided at both ends of the C-shaped plate 3141, the ends of which are located on the side of the C-shaped plate 3141 away from the connecting ring 305. A support base 315 is fixedly installed at the bottom of the C-shaped plate 3141. A relative movement drive mechanism 316 is provided at the top of the base 1. 316 is used to drive the two support seats 315 to move relative to each other. The pressure heads 313 corresponding to the three side boxes 306 below contact the C-shaped plates 3141 on the extrusion piece 314, so that the three side surfaces of the motor housing except the top wall coincide with the corresponding mounting plates 309. This allows the other three sides to be clamped by the clamping pieces 310, and there are no obstructions above the motor housing. This makes it convenient for the laser measuring instrument 205 to perform laser measurement on the upper surface of the motor housing. The side box 306, which was originally located at the top, can be directly clamped after rotating downwards, improving the stability of the motor's dimensional measurement.

[0044] The clamping member 310 includes a cylinder body 3101, on which an air intake pipe 3102 and an exhaust pipe 3103 are installed. One end of the air intake pipe 3102 is connected to an air pump 3104. A first solenoid valve 3105 and a one-way valve are installed on the air intake pipe 3102. A second solenoid valve 3106 is installed on the exhaust pipe 3103. When the pressure head 313 is subjected to the pressure of the C-shaped plate 3141, the contact 403 contacts the first contact block 401, and the second contact block 502 contacts the conductive strip 505, so that the circuits of the first solenoid valve 3105 and the second solenoid valve 3106 are connected, so that the clamping member 310 performs the clamping work. When the side box 306 rotates to the position corresponding to the empty slot 3143, the corresponding cylinder body 3101 exhausts, which facilitates the retraction of the mounting plate 309.

[0045] The exhaust control assembly 4 includes two contacts 403 mounted on the internal block 307, which are electrically connected. First electrical blocks 401 are symmetrically mounted on the inner walls of both sides of the side box 306. The first electrical blocks 401 are located on the side of the contacts 403 near the clamping member 310. First electrical sockets 402 are symmetrically mounted on the outer side of the side box 306. The first electrical blocks 401 and the first electrical sockets 402 are electrically connected. A disconnecting element 404 is provided on the side of the first electrical blocks 401 away from the contacts 403. A second solenoid valve 3106 and a power supply are connected in series between the two first electrical sockets 402. The first electrical block 401 is composed of a conductive substrate electrically connected to the first electrical socket 402 and two elastic electrical contacts, forming a U-shape.

[0046] The disconnecting power-off component 404 includes a fixed housing 4041 disposed on the side of the first contact block 401 away from the contact 403. The fixed housing 4041 is fixedly installed on the side housing 306. A guide groove 4042 is provided on the side of the fixed housing 4041 near the first contact block 401. Two push arms 4043 are symmetrically and slidably installed on the inner side of the guide groove 4042. The two push arms 4043 are located between two elastic contact pieces. A sliding plate 4044 is slidably installed inside the fixed housing 4041. Two first connecting rods 4045 are symmetrically hinged on the side of the sliding plate 4044 near the guide groove 4042. The ends of the two first connecting rods 4045 are respectively hinged to the two push arms 4043. A rod groove 4046 is provided on one side of the fixed housing 4041. The opening surface of the rod groove 4046 is perpendicular to the opening surface of the guide groove 4042. A movable rod 4047 is movably installed inside the rod groove 4046. A connecting block 4048 is installed at one end of the 7. A second connecting rod 4049 is hinged to one side of the connecting block 4048. The other end of the second connecting rod 4049 is hinged to the sliding plate 4044. A second spring 40410 is installed on the side of the connecting block 4048 near the movable rod 4047. One end of the second spring 40410 is fixedly connected to the inner wall of the fixed box 4041. A counterweight 40411 is installed at the other end of the movable rod 4047. When the side box 306 rotates to the uppermost position, the counterweight 40411 is in a vertically downward state, allowing it to overcome resistance and move downward, thereby pushing the two push arms 4043 away from each other. The two push arms 4043 are located between the two elastic contact plates of the first contact block 401, allowing the two elastic contact plates to open and separate from the contact 403. This facilitates the venting of the clamping member 310 before the mounting plate 309 moves back, preventing the mounting plate 309 from affecting the motor.

[0047] The intake control assembly 5 includes an inner cavity 501 formed inside the pressure receiving head 313. Second electrical contact blocks 502 are symmetrically mounted on both sides of the inner wall of the inner cavity 501, and second electrical contact sockets 503 are symmetrically mounted on the outer wall of the pressure receiving head 313. The second electrical contact blocks 502 and second electrical contact sockets 503 are electrically connected. An insulating plate 504 is movably mounted inside the inner cavity 501, and a conductive strip 505 is mounted on the insulating plate 504, located near the second electrical contact blocks 502. On one side of the side box 306, a push rod 507 is symmetrically installed on the side of the insulating plate 504 near the side box 306. One end of the push rod 507 extends through to the side of the pressure head 313 near the side box 306. A third spring 506 is symmetrically installed on the side of the insulating plate 504 near the side box 306. One end of the third spring 506 is fixedly connected to the inner wall of the end of the inner cavity 501. A first solenoid valve 3105 and a second power supply are connected in series between the two second electrical terminals 503.

[0048] The laser measurement position adjustment assembly 2 includes a rotating platform 201 fixedly installed on the top of the base 1. A rotating mounting bracket 202 is rotatably installed on the inner side of the rotating platform 201. A rotation drive mechanism for driving the rotating mounting bracket 202 to rotate is installed on the rotating platform 201. A lateral movement mechanism 203 is installed on the top of the rotating mounting bracket 202. A side movement mechanism 204 is installed on the lateral movement mechanism 203. The laser measuring instrument 205 is installed on the side movement mechanism 204.

[0049] Working principle: During operation, the motor for which laser measurement is required is first placed between the two connecting rings 305. Then, the relative movement drive mechanism 316 is activated, driving the two extrusion pieces 314 to move closer together, so that the C-shaped plate 3141 contacts the three pressure heads 313. The uppermost pressure head 313 corresponds to the slot 3143, causing the C-shaped plate 3141 to push the three pressure heads 313 to move, which in turn pushes the mounting plate 309 to move to the position coinciding with the motor. At this time, the two contacts 403 on the internal block 307 are respectively inserted into the inside of the two first energizing blocks 401, so that the circuit of the second solenoid valve 3106 is connected. This causes the second solenoid valve 3106 to be energized and closed. At the same time, when the pressure head 313 approaches the side box 306, the push rod 507 is limited by the side box 306, causing the conductive strip 505 to move toward the second contact block 502 until it contacts the two second contact blocks 502, thus connecting the circuit of the first solenoid valve 3105 and energizing and opening the first solenoid valve 3105. At the same time, a one-way valve is provided on the air intake pipe 3102, causing the air pump 3104 to continuously input air into the cylinder 3101, pushing the output rod in the cylinder 3101 to extend outward until one end of the output rod contacts the motor, and multiple output rods clamp and fix the motor.

[0050] Then, the dimensions are measured by laser. The laser measuring instrument 205 is moved and its position is adjusted by the transverse moving mechanism 203 and the lateral moving mechanism 204. The laser measuring instrument 205 emits a laser beam toward the surface of the motor below, and the dimensions of the motor are measured by the laser beam.

[0051] After measuring the surface dimensions on one side of the motor, the drive motor 303 is turned on, driving the gear 302 to rotate. The gear 302 meshes with the gear ring 304 on the inner side of the ring frame 301, thereby causing the gear ring 304 to rotate 90 degrees. During the rotation, the original uppermost part moves downward. During the transfer, the end of the pressure head 313 first contacts the end of the bending part 3142, and under the action of the bending part 3142, the pressure head 313 moves towards the side box 306 until the mounting plate 309 moves to the position overlapping with the motor. At this time, the output rod in the cylinder 3101 moves outward to clamp the motor, while the other side box 306 rotates to the uppermost position, so that the pressure head 313 corresponds to the empty slot 3143. At this time, the internal block 307 moves back under the elastic force of the first spring 311, causing the mounting plate 309 to move back, so that the mounting plate 309 will not obstruct the top of the motor, which is convenient for laser measurement.

[0052] When the side box 306 is rotated to its highest position, the counterweight 40411 on the fixed box 4041 is in a vertically downward position. At this time, the counterweight 40411 moves downward under the action of gravity, overcoming the elastic force of the second spring 40410. This pushes the sliding plate 4044 towards the guide groove 4042 via the second connecting rod 4049. Subsequently, the two first connecting rods 4045 push the two push arms 4043 away from each other along the guide groove 4042, thereby exerting pressure on the two elastic conductive plates on the first contact block 401. This causes the two elastic conductive plates to open and separate from the contact 403, thus allowing the side box to... When the housing 306 rotates to the top, the circuits of the second solenoid valve 3106 and the first solenoid valve 3105 are completely disconnected, causing the first solenoid valve 3105 to close and the second solenoid valve 3106 to open. At this time, the air inside the cylinder 3101 is directly discharged from the exhaust pipe 3103, causing the output rod to move back, so that the output rod will not cause obstruction during the retraction of the mounting plate 309. The cylinder 3101 is equipped with an output rod and a spring connected to the output rod. After the air is introduced, the air pressure increases and pushes the output rod to move outward, while the spring is stretched. When the air is discharged, the output rod retracts under the action of the spring force.

[0053] Repeat the above steps to inspect the four sides of the motor.

[0054] Then, the rotating drive mechanism on the rotating table 201 drives the rotating mounting bracket 202 to rotate 90 degrees clockwise, so that the laser measuring instrument 205 performs laser measurement of the dimensions of one end of the motor from the connecting ring 305 on one side. Then, the rotating drive mechanism drives the rotating mounting bracket 202 to rotate 180 degrees counterclockwise, so that the laser measuring instrument 205 performs laser measurement of the dimensions of the other end of the motor from the connecting ring 305 on the other side, thereby completing the measurement of the dimensions of each surface of the motor.
