Description

Technical Field

[0001] The present invention relates to the technical field of reducer housing detection, and particularly to a detection device and a usage method for machining hole positions of a reducer housing. Background Art

[0002] The reducer housing is an important part of the reducer. As an external protection structure, it not only provides support and assembly space for internal components such as gears and bearings, but also plays roles in sealing, protection, and heat dissipation. During the production process of the reducer housing, holes need to be drilled. This process involves drilling holes for the installation and assembly of the reducer. After the drilling is completed, it is necessary to check whether the hole positions meet the requirements and whether they can be assembled or fixed well.

[0003] If the method of corresponding pairing of one side of the reducer housing with the other side is used to detect whether the hole positions are qualified, it will greatly increase the detection time and significantly reduce the production efficiency. While the hole position detection device for the reducer housing can perform corresponding detection on the hole positions of the reducer housing, which can avoid the drawbacks of pairing the reducer housings. However, most of these detection methods can only detect the positions of the hole positions and cannot detect the accuracy of the hole positions, and it is difficult to visually display the shape changes of the hole positions during the detection process, which may affect the assembly accuracy of the subsequent reducer housing.

[0004] Therefore, it is necessary to provide a detection device and a usage method for machining hole positions of a reducer housing to solve the above problems. Summary of the Invention

The laser sensors are located on the connecting line between the center of the supporting turntable and the corresponding infrared receivers. An infrared emitter is provided at one end of the workbench close to the adjusting assembly. The infrared emitter is movably corresponding to the infrared receiver.

[0009] As a further solution of the present invention, the rotating assembly includes a driven bevel gear arranged at one end of the rotating column passing through the workbench. A rotating motor is installed at the bottom of the workbench. The output end of the rotating motor is connected with a driving bevel gear meshing with the driven bevel gear.

[0010] As a further solution of the present invention, the adjusting assembly includes a vertical plate installed at the end of the workbench. On one side of the top of the vertical plate close to the positioning assembly, a horizontal frame is installed. Support chutes are opened on both side walls of the horizontal frame. A sliding threaded plate that is slidably matched with the support chutes is movably arranged inside the horizontal frame. A screw rod is rotatably connected between the outer end of the horizontal frame and the vertical plate. The screw rod is in threaded cooperation with the sliding threaded plate. One end of the screw rod is connected with an adjusting motor.

[0011] As a further solution of the present invention, the lifting assembly includes an electric cylinder and a guide tube installed at the bottom of the sliding threaded plate. A spiral chute is arranged inside the guide tube. A lifting rod is movably arranged inside the guide tube. A spiral piece that is slidably matched with the spiral chute is spirally arranged on the outer side of the lifting rod. The bottom of the lifting rod is rotatably connected with a connecting plate connected to the extending end of the electric cylinder. The bottom end of the lifting rod is connected with the detection assembly.

[0012] As a further solution of the present invention, the detection assembly includes a laser displacement sensor installed at the bottom of the lifting rod. A connecting cylinder is connected to the bottom of the laser displacement sensor. A side groove is opened on the side wall of the connecting cylinder.

[0016] A method for using a machining hole position detection device for a reducer housing, applicable to the machining hole position detection device for a reducer housing described above, is characterized by including the following steps:

[0017] Step S1: The positioning component fixes the position of the reducer housing and confirms the hole positions to be measured on the reducer housing. If the positions of the holes to be measured are correct, the subsequent detection stage is entered; if the positions of the holes to be measured are incorrect, the subsequent detection stage is not entered.

[0018] Step S2: The rotating component drives the reducer housing to rotate synchronously by driving the positioning component to rotate. When the reducer housing rotates to the corresponding position, the adjusting component drives the lifting component and the detection component to move to directly above the hole to be measured.

[0019] Step S3: The lifting component performs a primary detection on the shape change of the hole to be measured by pushing the detection component downward through the hole to be measured, and the lifting component performs a secondary detection on the shape change of the hole to be measured by pulling the detection component upward through the hole to be measured again, and the controller displays the two detection data.

[0020] In summary, the embodiments of the present invention have the following beneficial effects compared with the prior art:

[0021] 1. In the present invention, according to the distribution positions of several L-shaped positioning rods and laser sensors, the reducer housing is placed between several L-shaped positioning rods, so that the L-shaped positioning rods are in contact with the outer wall of the reducer housing, thereby fixing the angle of the reducer housing. When the reducer housing moves downward to contact the electric suction cup, the bottom of the reducer housing is adsorbed through the electric suction cup to fix the position of the reducer housing; at the same time, through several laser sensors, the hole positions to be measured of the reducer housing can be confirmed. When the result detected by the laser sensor cannot correspond to the hole positions to be measured of the reducer housing, it means that the machining hole positions of the reducer housing are incorrect, that is, there is no need to perform subsequent shape change detection on the hole positions.

[0022] 2. In the present invention, when the infrared emitter corresponds to one of the infrared receivers, the adjusting motor is driven to rotate the screw rod, so that the sliding threaded plate moves to directly above the corresponding hole to be measured; then, the electric cylinder extends downward and drives the connecting plate to move downward. The connecting plate drives the lifting rod to spiral downward by means of rotational cooperation with the lifting rod and sliding cooperation between the spiral piece and the spiral chute. The lifting rod drives the detection assembly to spiral downward synchronously to detect the shape of the corresponding hole to be measured; after one detection is completed, the electric cylinder contracts upward and drives the connecting plate to move upward. The connecting plate drives the lifting rod to spiral upward by means of rotational cooperation with the lifting rod and sliding cooperation between the spiral piece and the spiral chute. The lifting rod drives the detection assembly to spiral upward synchronously to perform a secondary detection on the shape of the corresponding hole to be measured. By driving the detection assembly to spiral downward and upward, the shape of the hole to be measured can be double-detected, improving the detection accuracy and avoiding errors that may occur in single detection;

[0023] 3. In the present invention, during the process of the outer end of the abutting rod contacting the inner wall of the hole to be measured, if the shape of the hole to be measured does not change, the distance from the outer end of the abutting rod to the connecting cylinder is fixed. At this time, the pressure or tension received by the strain gauge sensor remains unchanged. If the shape of the hole to be measured changes, the distance from the outer end of the abutting rod to the connecting cylinder changes. The abutting rod drives the gear part to rotate correspondingly. The gear part drives the lifting slide plate to rise or fall correspondingly by meshing with the sliding rack and the sliding cooperation between the sliding rack and the connecting cylinder, so that the spring reduces or increases the deformation amount. The pressure or tension received by the strain gauge sensor will change accordingly, and this change will be intuitively reflected on the controller, facilitating the staff to quickly and intuitively observe the shape change of the hole to be measured.

[0039] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to 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 used to limit the present invention.

[0040] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0041] In an embodiment of the present invention, refer to Figures 1-3, a machining hole position detection device for a reducer housing, comprising a bracket assembly 1. The bracket assembly 1 includes a workbench 101. A positioning assembly 2 for fixing the reducer housing 8 is rotatably provided on the workbench 101. A rotating assembly 3 connected to the positioning assembly 2 is provided at the bottom of the workbench 101. An adjusting assembly 4 is installed at one end of the workbench 101. A lifting assembly 5 is provided on the adjusting assembly 4. A detection assembly 6 for detecting the hole position is provided at the bottom of the lifting assembly 5. A controller 7 electrically connected to the electrical equipment inside the device is provided on the adjusting assembly 4.

[0042] In this embodiment, through the positioning assembly 2, the reducer housing 8 can be positioned, and at the same time, it can be confirmed whether the hole positions of the holes to be measured on the reducer housing 8 are correct. The rotating assembly 3 drives the reducer housing 8 to rotate synchronously by driving the positioning assembly 2 to rotate. When the hole position rotates to the corresponding position, the adjusting assembly 4 drives the detection assembly 6 to move synchronously by driving the lifting assembly 5 to move synchronously, so that the detection assembly 6 corresponds to the hole position. The lifting assembly 5 drives the detection assembly 6 to move downward, so that the detection assembly 6 passes through the hole to be measured, and the shape change of the hole to be measured can be detected. Through the controller 7, the staff can control the start and stop of the electrical equipment inside the device, and at the same time, the detection results can be displayed, which is convenient for the staff to directly observe the shape change of the hole to be measured. It has the effects of stable positioning, flexible rotation, hole position confirmation, meeting the hole position detection requirements of different positions, flexible and efficient detection, reliable structure and convenient operation;

[0043] Among them, support frames 102 are symmetrically installed at the bottom of the workbench 101. The support frames 102 can be set as U-shaped plates, which can stably support the workbench 101.

[0044] In an embodiment of the present invention, see Figures 1-3 , the positioning assembly 2 includes a support turntable 201 rotatably provided on the workbench 101. A rotating column 202 is installed on the support turntable 201. A plurality of brackets 203 are circumferentially installed at the top of the rotating column 202. Electric suction cups 204 that fit the bottom of the reducer housing 8 are connected to the outer ends of the brackets 203. A plurality of L-shaped positioning rods 205 are circumferentially installed at the top of the rotating column 202. The outer ends of the L-shaped positioning rods 205 are in contact with the outer edge of the reducer housing 8. A plurality of laser sensors 206 corresponding to the hole positions of the reducer housing 8 are distributed on the support turntable 201. A plurality of infrared receivers 207 corresponding to the laser sensors 206 are distributed on the outer edge of the support turntable 201. The laser sensors 206 are located on the connection line between the center of the support turntable 201 and the corresponding infrared receivers 207. An infrared emitter 208 is provided at one end of the workbench 101 close to the adjusting assembly 4. The infrared emitter 208 is movably corresponding to the infrared receivers 207.

[0045] In this embodiment, according to the distribution positions of a plurality of L-shaped positioning rods 205 and laser sensors 206, the reducer housing 8 is placed between the plurality of L-shaped positioning rods 205, so that the L-shaped positioning rods 205 are in contact with the outer wall of the reducer housing 8, thereby fixing the angle of the reducer housing 8. When the reducer housing 8 moves down to contact the electric suction cup 204, the bottom of the reducer housing 8 is adsorbed by the electric suction cup 204 to fix the position of the reducer housing 8;

[0046] Meanwhile, through a plurality of laser sensors 206, the to-be-measured hole positions of the reducer housing 8 can be confirmed. When the result detected by the laser sensor 206 cannot correspond to the to-be-measured hole positions of the reducer housing 8, it means that the processed hole positions of the reducer housing 8 are incorrect, that is, there is no need to perform subsequent shape change detection on the hole positions;

[0047] When the result detected by the laser sensor 206 corresponds to the to-be-measured hole positions of the reducer housing 8, the rotation assembly 3 drives the reducer housing 8 to rotate synchronously by driving the support turntable 201 to rotate. During the rotation process, when one of the infrared receivers 207 corresponds to the infrared emitter 208, the rotation assembly 3 stops working. Through the cooperation of the adjustment assembly 4, the lifting assembly 5 and the detection assembly 6, the shape change of the corresponding to-be-measured hole can be detected. After the detection is completed, the adjustment assembly 4, the lifting assembly 5 and the detection assembly 6 are reset. The controller 7 can display the detection data. Meanwhile, the rotation assembly 3 drives the positioning assembly 2 to continue rotating. When the next infrared receiver 207 corresponds to the infrared emitter 208, the rotation assembly 3 stops working. Through the cooperation of the adjustment assembly 4, the lifting assembly 5 and the detection assembly 6, the shape change of the to-be-measured hole can be detected. By corresponding the infrared emitter 208 to different infrared receivers 207 respectively, the shape change of the to-be-measured holes on the reducer housing 8 can be comprehensively and quickly detected, improving the practicability of the device.

[0048] In one embodiment of the present invention, refer to Figures 1-3 , the rotation assembly 3 includes a driven bevel gear 303 disposed at one end of the rotating column 202 passing through the workbench 101. A rotation motor 301 is installed at the bottom of the workbench 101, and an output end of the rotation motor 301 is connected to a driving bevel gear 302 that meshes with the driven bevel gear 303.

[0049] In this embodiment, the rotary motor 301 drives the driving bevel gear 302 to rotate. The driving bevel gear 302 drives the rotating column 202 and the supporting turntable 201 to rotate synchronously by engaging with the driven bevel gear 303, thereby driving the reducer housing 8 and the infrared receiver 207 to rotate synchronously. When the infrared emitter 208 corresponds to one of the infrared receivers 207, the rotary motor 301 stops working, facilitating the shape change detection of the to-be-detected hole by the detection assembly 6. After the detection is completed, the rotary motor 301 drives the driving bevel gear 302 to continue rotating. When the infrared emitter 208 corresponds to the next infrared receiver 207, the rotary motor 301 stops working again, and the shape change detection of the to-be-detected hole is carried out by the detection assembly 6. When the infrared emitter 208 corresponds to the infrared receiver 207, the rotary motor 301 stops working. After the shape detection of the to-be-detected hole is completed, the rotary motor 301 resumes operation. By continuously starting and stopping the rotary motor 301, a comprehensive detection of the to-be-detected holes located on the reducer housing 8 can be achieved.

[0050] In one embodiment of the present invention, referring to Figures 1-5 , the adjusting assembly 4 includes a vertical plate 401 installed at the end of the workbench 101. A cross frame 402 is installed on the top of the vertical plate 401 near one side of the positioning assembly 2. Support sliding grooves 403 are formed on both side walls of the cross frame 402. A sliding threaded plate 404 that is slidably matched with the support sliding grooves 403 is movably arranged in the cross frame 402. A screw rod 405 is rotatably connected between the outer end of the cross frame 402 and the vertical plate 401. The screw rod 405 is in threaded cooperation with the sliding threaded plate 404. One end of the screw rod 405 is connected to an adjusting motor 406;

[0051] The lifting assembly 5 includes an electric cylinder 501 and a guide tube 502 installed at the bottom of the sliding threaded plate 404. A spiral sliding groove 505 is formed inside the guide tube 502. A lifting rod 503 is movably arranged inside the guide tube 502. A spiral piece 504 that is slidably matched with the spiral sliding groove 505 is spirally arranged on the outer side of the lifting rod 503. The bottom of the lifting rod 503 is rotatably connected to a connecting plate 506 connected to the extending end of the electric cylinder 501. The bottom end of the lifting rod 503 is connected to the detection assembly 6.

[0052] In this embodiment, in the initial state, the sliding threaded plate 404 is close to the vertical plate 401. At this time, the connecting plate 506 is at the highest point, and the detection assembly 6 is located at the uppermost position;

[0053] When the infrared emitter 208 corresponds to one of the infrared receivers 207, the adjustment motor 406 drives the screw 405 to rotate. The screw 405 drives the sliding threaded plate 404 away from the vertical plate 401 by means of being threadedly connected to the sliding threaded plate 404 and the sliding threaded plate 404 being slidably fitted with the support chute 403, so that the sliding threaded plate 404 moves to directly above the corresponding hole to be measured. Then, the electric cylinder 501 extends downward and drives the connecting plate 506 to move downward. The connecting plate 506 drives the lifting rod 503 to spiral downward by means of being rotatably fitted with the lifting rod 503 and the spiral piece 504 being slidably fitted with the spiral chute 505. The lifting rod 503 drives the detection assembly 6 to spiral downward synchronously to detect the shape of the corresponding hole to be measured.

[0054] After one detection is completed, the electric cylinder 501 contracts upward and drives the connecting plate 506 to move upward. The connecting plate 506 drives the lifting rod 503 to spiral upward by means of being rotatably fitted with the lifting rod 503 and the spiral piece 504 being slidably fitted with the spiral chute 505. The lifting rod 503 drives the detection assembly 6 to spiral upward synchronously to perform a secondary detection on the shape of the corresponding hole to be measured.

[0055] Finally, the electric cylinder 501 returns to its original length, and the connecting plate 506 resets to the highest point, facilitating the subsequent hole position detection of the reducer housing 8.

[0056] By driving the detection assembly 6 to spiral downward and upward, the shape of the hole to be measured can be double-detected, improving the detection accuracy and avoiding errors that may occur in single detection.

[0057] In an embodiment of the present invention, referring to Figures 1-6 , the detection assembly 6 includes a laser displacement sensor 601 installed at the bottom of the lifting rod 503. The bottom of the laser displacement sensor 601 is connected to a connecting cylinder 602. A side groove 603 is opened on the side wall of the connecting cylinder 602. A fixed rod 605 is installed inside the connecting cylinder 602. A gear portion 606 is rotatably provided on the outer side of the fixed rod 605. The outer end of the gear portion 606 is connected to an abutting rod 604 that is movably fitted with the side groove 603. A sliding rack 607 that meshes with the gear portion 606 is slidably provided inside the connecting cylinder 602. The end of the sliding rack 607 is connected to a lifting sliding plate 608. A strain gauge sensor 610 is installed at the inner bottom of the connecting cylinder 602. A spring 609 is connected between the strain gauge sensor 610 and the lifting sliding plate 608.

[0058] In this embodiment, in the initial state, the abutting rod 604 is in a horizontal state. The distances from both ends of the sliding rack 607 to the fixed rod 605 are equal. The spring 609 is in its original length. The distance from the outer end of the abutting rod 604 to the connecting cylinder 602 is at its maximum value.

[0059] After the sliding threaded plate 404 moves to directly above the hole to be measured, the electric cylinder 501 extends downward and drives the connecting plate 506 to move downward. The connecting plate 506 drives the lifting rod 503 to move downward in a spiral manner through the rotational cooperation with the lifting rod 503 and the sliding cooperation between the spiral piece 504 and the spiral chute 505. The lifting rod 503 drives the laser displacement sensor 601 and the connecting cylinder 602 to move downward in a spiral synchronously, so that the connecting cylinder 602 extends into the interior of the hole to be measured;

[0060] After the abutting rod 604 starts to contact the top of the hole to be measured, the laser displacement sensor 601 and the connecting cylinder 602 continue to move downward in a spiral. The abutting rod 604 rotates upward around the fixed rod 605 under the reaction force of the top of the hole to be measured. The distance from the outer end of the abutting rod 604 to the connecting cylinder 602 becomes smaller. During this process, the abutting rod 604 drives the gear part 606 to rotate synchronously. The gear part 606 drives the lifting slide plate 608 to move downward through the meshing with the sliding rack 607 and the sliding cooperation between the sliding rack 607 and the connecting cylinder 602. Since the position of the strain gauge sensor 610 is fixed, the lifting slide plate 608 pushes the spring 609 downward, making the spring 609 in a compressed state. The pressure received by the strain gauge sensor 610 increases, and the strain gauge sensor 610 transmits the pressure data received to the controller 7 for display through the controller 7;

[0061] When the abutting rod 604 rotates upward to a certain angle, the outer end of the abutting rod 604 contacts the inner wall of the hole to be measured. At this time, the distance from the outer end of the abutting rod 604 to the connecting cylinder 602 is at the minimum value. When the laser displacement sensor 601 and the connecting cylinder 602 continue to move downward in a spiral, during the process of the outer end of the abutting rod 604 contacting the inner wall of the hole to be measured, if the shape of the hole to be measured does not change, the distance from the outer end of the abutting rod 604 to the connecting cylinder 602 is fixed. At this time, the pressure received by the strain gauge sensor 610 remains unchanged. If the shape of the hole to be measured changes, the distance from the outer end of the abutting rod 604 to the connecting cylinder 602 changes, and the abutting rod 604 will drive the gear part 606 to rotate correspondingly. The gear part 606 drives the lifting slide plate 608 to rise or fall correspondingly through the meshing with the sliding rack 607 and the sliding cooperation between the sliding rack 607 and the connecting cylinder 602, so that the spring 609 reduces or increases the compression amount, and the pressure received by the strain gauge sensor 610 will decrease or increase correspondingly. This change will be intuitively reflected on the controller 7, facilitating the staff to intuitively observe the shape change of the hole to be measured;

[0062] When the abutting rod 604 passes through the hole to be measured, the abutting rod 604 returns to the horizontal state under the elastic action of the spring 609. At this time, the pressure received by the strain gauge sensor 610 is zero. Through the laser displacement sensor 601, the aperture of the hole to be measured can be detected;

[0063] Then, the electric cylinder 501 receives an upward force and drives the lifting rod 503 to move upward in a spiral manner. The lifting rod 503 drives the laser displacement sensor 601 and the connecting cylinder 602 to move upward synchronously in a spiral manner. The abutting rod 604 rotates downward around the fixed rod 605 under the reaction force at the bottom of the hole to be measured. The distance from the outer end of the abutting rod 604 to the connecting cylinder 602 becomes smaller. During this process, the abutting rod 604 drives the gear part 606 to rotate synchronously. The gear part 606 drives the lifting slide plate 608 to move upward by meshing with the sliding rack 607 and the sliding cooperation between the sliding rack 607 and the connecting cylinder 602. Since the position of the strain gauge sensor 610 is fixed, the lifting slide plate 608 pulls the spring 609 upward, causing the spring 609 to be in a stretched state. The pulling force received by the strain gauge sensor 610 increases, and the strain gauge sensor 610 transmits the received pulling force data to the controller 7 for display by the controller 7;

[0064] When the abutting rod 604 rotates downward to a certain angle, the outer end of the abutting rod 604 contacts the inner wall of the hole to be measured. At this time, the distance from the outer end of the abutting rod 604 to the connecting cylinder 602 is at a minimum value. When the laser displacement sensor 601 and the connecting cylinder 602 continue to move upward in a spiral manner, during the process of the outer end of the abutting rod 604 contacting the inner wall of the hole to be measured, if the shape of the hole to be measured does not change, the distance from the outer end of the abutting rod 604 to the connecting cylinder 602 is fixed. At this time, the pulling force received by the strain gauge sensor 610 remains unchanged. If the shape of the hole to be measured changes, the distance from the outer end of the abutting rod 604 to the connecting cylinder 602 changes, and the abutting rod 604 will drive the gear part 606 to rotate correspondingly. The gear part 606 drives the lifting slide plate 608 to rise or fall correspondingly by meshing with the sliding rack 607 and the sliding cooperation between the sliding rack 607 and the connecting cylinder 602, causing the spring 609 to increase or decrease the stretching amount. The pulling force received by the strain gauge sensor 610 will increase or decrease accordingly, and this change will be intuitively reflected on the controller 7, facilitating the staff to intuitively observe the shape change of the hole to be measured;

[0065] By detecting the shape of the hole to be measured twice, the possible errors in a single detection can be reduced, and the detection accuracy can be improved;

[0066] Among them, the length of the side groove 603 is not less than twice the length of the abutting rod 604, and the number of teeth of the fixed rod 605 is the same as that of the sliding rack 607.

[0067] In an embodiment of the present invention, refer to Figures 1-6 , a method for using a detection device for machining hole positions of a reducer housing, including the following steps:

[0068] Step S1: The positioning component 2 fixes the position of the reducer housing 8 and confirms the hole positions to be measured on the reducer housing 8. If the positions of the holes to be measured are correct, proceed to the subsequent detection stage; if the positions of the holes to be measured are incorrect, do not proceed to the subsequent detection stage.

[0069] Step S2: The rotation component 3 drives the reducer housing 8 to rotate synchronously by driving the positioning component 2 to rotate. When the reducer housing 8 rotates to the corresponding position, the adjustment component 4 drives the lifting component 5 and the detection component 6 to move to directly above the hole to be measured.

[0070] Step S3: The lifting component 5 performs a first detection of the shape change of the hole to be measured by pushing the detection component 6 downward through the hole to be measured, and performs a second detection of the shape change of the hole to be measured by pulling the detection component 6 upward through the hole to be measured again, and the controller 7 displays the two detection data.

[0071] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
