Description

Technical Field

[0001] This invention relates to the field of automatic gear inspection technology, and specifically to a gear internal bore inspection, grading and sorting device. Background Technology

[0002] Currently, many small and medium-sized manufacturers in the industry still rely on manual measurement for gear diameter. The methods for inspecting the inner ring diameter of gears include inspection with an inside micrometer and inspection with a dedicated go / no-go gauge. An inside micrometer can directly measure the inner ring diameter. Inspection with a dedicated go / no-go gauge involves machining the go gauge size to the lower limit of the inner ring diameter and the no-go gauge size to the upper limit of the inner ring diameter. During inspection, if the go gauge can pass through the hole and the no-go gauge cannot pass through the hole, the inner ring diameter is considered to be qualified. However, the current inspection process is not highly automated and has low work efficiency, which cannot meet people's needs.

[0003] In addition, the gears that have been inspected need to be classified and stored according to the inspection results. However, the current method is to inspect the gears manually by operators and separate the gears of different grades according to the inspection results. This method has poor inspection accuracy, high labor intensity and low efficiency. Summary of the Invention

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. In the technical solution of the present invention, an internal hole detection component and a robot arm component are provided on the lathe bed used for machining. This facilitates the transfer of the gear to be tested after rough machining by the robot arm component, which clamps and transfers the gear to be tested onto the internal hole detection component for internal hole detection. The internal hole detection component includes a base plate, a first lifting structure, and a detection table. The base plate is used to fix the gear on the lathe bed, and the first lifting structure is used to adjust the height. The gear to be tested can be pressed onto the internal hole detection component according to the gear height. Then, the probe on the detection table abuts against the inner wall of the hole of the gear to be tested. The probe on the detection table moves and detects in all directions, and transmits the detected displacement information to the display component. The display component analyzes and calculates the roundness value of the gear to be tested, thereby realizing the detection of the roundness, diameter, and coaxiality dimensions of the gear to be tested. After the gears have been inspected, in order to achieve graded sorting and storage of the inspected gears, a discharge bracket assembly is connected to one side of the lathe bed, and a storage assembly is installed on the discharge bracket assembly. The storage assembly is supported by a pusher base plate connected to the discharge bracket assembly. Multiple parallel material groove mechanisms and corresponding pusher mechanisms are set on one side of the material groove mechanisms on the pusher base plate. In this way, the robot arm assembly can horizontally clamp the gears to be inspected from the lathe bed and transfer them to the inspection table. Then, the first lifting structure lifts and presses against the upper end face of the gears to be inspected. The inspection table inspects the inner diameter of the gears to be inspected. Then, the robot arm assembly moves to horizontally clamp the inspected gears and transfer them to the corresponding material groove mechanism of the storage assembly.

[0063] Please see Figure 1-13 As shown, the present invention provides a gear inner hole detection, grading, and sorting device. This device is used to detect the inner hole size of the gear 6 being tested. The device includes a discharge support assembly 1, an inner hole detection assembly 2, a robotic arm assembly 3, and a storage assembly 4, wherein:

[0064] In order to achieve the fixed installation of the storage component 4, in this embodiment, the discharge bracket assembly 1 is connected to one side of the lathe bed. After the processed gear 6 is quickly inspected by the inner hole detection assembly 2, it can be transferred to the storage component 4 by the robot arm assembly 3.

[0065] To facilitate the inspection and storage of the machined gear 6, the robotic arm assembly 3 in this embodiment is mounted above the lathe bed. The robotic arm assembly 3 can horizontally clamp and transfer the gear 6 to the inner hole inspection assembly 2 and the storage assembly 4.

[0066] The gear 6 that has been preliminarily processed still needs to be inspected for size. For this purpose, the inner hole inspection component 2 is installed between the lathe bed and the robot arm component 3. In this embodiment, the inner hole inspection component 2 includes a base plate 21, a first lifting structure 22 and an inspection table 23. The base plate 21 is connected to the lathe bed, and the first lifting structure 22 and the inspection table 23 are installed on the upper surface of the base plate 21.

[0067] To facilitate the grading and storage of the batch of tested gears 6 after inspection based on the inspection results, this gear inner hole inspection and grading sorting device is also equipped with a storage component 4. The storage component 4 is connected to the discharge bracket assembly 1. The storage component 4 includes a pusher base plate 41, a pusher mechanism 42, and a material trough mechanism 43. The pusher base plate 41 is connected to the discharge bracket assembly 1. Multiple parallel material trough mechanisms 43 are installed on the pusher base plate 41. A pusher mechanism 42 is also provided on the inlet side of the material trough mechanism 43. The test gears 6 placed horizontally at the corresponding inlet can be pushed into the material trough mechanism 43 by the pusher mechanism 42.

[0068] The robotic arm assembly 3 can horizontally clamp the gear 6 to be tested from the lathe bed and transfer it to the testing table 23. Then, the first lifting structure 22 lifts and presses against the upper end face of the gear 6 to be tested. The testing table 23 tests the inner hole size of the gear 6 to be tested. The robotic arm assembly 3 moves to horizontally clamp the tested gear 6 and transfer it to the storage assembly 4. The pushing mechanism 42 is adapted to move to push the corresponding tested gear 6 into the corresponding material trough mechanism 43 for storage.

[0069] In the technical solution of the present invention, by setting the first lifting structure 22 and the detection platform 23 of the inner hole detection component 2, the gear 6 to be tested can be positioned. Then, the probe in the detection platform 23 abuts against the inner hole sidewall of the gear 6 to be tested. When the probe performs all-round detection on the inner hole of the gear 6 to be tested, the detected displacement information is transmitted to the display component. The display component analyzes and calculates to obtain the roundness value of the gear 6 to be tested, thereby realizing the detection of the roundness dimension and coaxiality of the gear 6 to be tested.

[0070] The gear inner hole detection, grading and sorting device provided by the present invention can simultaneously detect multiple dimensions such as roundness, coaxiality and diameter of the gear 6 being tested, which greatly saves detection time and improves production efficiency.

[0071] In addition, the robotic arm component 3 moves horizontally to pick up the tested gear 6 and transfer it to the corresponding material trough mechanism 43 of the storage component 4. The corresponding pushing mechanism 42 is adapted to move to push the tested gear 6 into the corresponding material trough mechanism 43 for storage, so as to realize the hierarchical and classified storage of batch tested gears 6.

[0072] Furthermore, in this invention, the gear inner hole detection and sorting device also includes a display component 5 installed on one side of the robotic arm assembly 3. The display component 5 includes a display bracket 51 and a display 52. ​​The display bracket 51 is connected to the robotic arm assembly 3, while the display 52 is embedded in the display bracket 51.

[0073] Therefore, by setting the display component 5, on the one hand, the operation process can be controlled according to the process, and on the other hand, the measurement classification standard of the gear 6 to be tested and the corresponding material trough setting of the storage component 4 can be stored in advance. When the gear 6 to be tested is internally judged, it will be sent into the corresponding material trough mechanism 43 under the driving action of the robot component 3.

[0074] Further, please refer to Figure 4 As shown, in this embodiment, the first lifting structure 22 includes a pad 221, a lifting cylinder bracket 222, a slide rail structure 223, and a three-axis cylinder 224, wherein:

[0075] The shim 221 is located on the base plate 21 and is used to adjust the level of the base plate 21. The lifting cylinder bracket 222 is installed on the shim 221 and is used to install the three-axis cylinder 224 according to the height of the gear 6 being tested. In order to vertically install and fix the three-axis cylinder 224 on the lifting cylinder bracket 222, in this embodiment, the slide rail structure 223 is provided on the surface of the lifting cylinder bracket 222 and the three-axis cylinder 224 on the opposite side. The three-axis cylinder 224 can slide up and down on the lifting cylinder bracket 222 through the slide rail structure 223.

[0076] For details, please refer to Figure 4 As shown, in this embodiment, the testing platform 23 includes a raising block 231, a measuring sleeve 232, a lower pressure plate 233, and a measuring head 234, wherein:

[0077] The shim block 231 is connected to the base plate 21 and is used to adjust the level of the measuring sleeve 232. The measuring sleeve 232 is installed on the shim block 231. A drivable measuring head 234 is provided inside the measuring sleeve 232. One end of the lower pressure plate 233 is horizontally connected to the top of the three-axis cylinder 224. In this way, the lower pressure plate 233 can move up and down under the up and down driving action of the three-axis cylinder 224. The measuring head 234 is located between the measuring sleeve 232 and the lower pressure plate 233. The lower pressure plate 233 has a measuring hole that allows the gear 6 to be measured to be placed in the position directly opposite the measuring head 234. The measuring hole is located at the center of the measuring sleeve 232. The measuring head 234 can be inserted into the interior of the gear 6 under the action of the measuring sleeve 232 and measure the inner hole of the gear 6.

[0078] Please see Figure 12 , Figure 13As shown, in this embodiment of the invention, the measuring head 234 includes a gas source 2341, a regulating valve 2342, a pressure gauge 2343, a first control valve 2344, a second control valve 2345, a differential pressure sensor 2346, a gear 6 to be tested (i.e., the gear to be detected), and a standard gear (reference standard gear). The gas supplied by the gas source 2341 passes through the regulating valve 2342, the pressure gauge 2343, and the first control valve 2344 to the gear 6 to be tested. The gas supplied by the gas source 2341 passes through the regulating valve 2342, the pressure gauge 2343, and the second control valve 2345 to the standard gear. The pressure difference between the two gears is measured by the differential pressure sensor 2346 connected between them to obtain the differential pressure between the gear 6 to be tested and the standard gear, and the pressure difference information is converted into information such as the diameter error of the actual gear 6 to be tested.

[0079] In order to enable the air pressure measurement of the measuring head 234, multiple internal air channels 2341 are provided inside the measuring head 234, and the measurement is driven by the delivery of gas in the air channels 2341.

[0080] It should be noted that the measuring head 234 can obtain the diameter of the gear 6 being measured by using trigonometric formulas and based on the differential pressure information detected by the differential pressure sensor, thus saving inspection time and improving production efficiency.

[0081] Further, please refer to Figure 2 and Figure 7 The testing platform 23 also includes an upper pressure plate 235 and a first drive cylinder 236, wherein:

[0082] The upper pressure plate 235 is located above the measuring sleeve 232 and the lower pressure plate 233. The first driving cylinder 236 is vertically embedded in the lower pressure plate 233. The first driving cylinder 236 is located between the first lifting structure 22 and the detection table 23. The upper pressure plate 235 is adapted to be rotatably connected to the top of the output shaft of the first driving cylinder 236.

[0083] Therefore, by setting the upper pressure plate 235, when the robot arm assembly 3 horizontally clamps the gear 6 to be tested onto the lower pressure plate 233, the first drive cylinder 236 drives the upper pressure plate 235 to move up and down and press it against the upper end face of the gear 6 to be tested. After the test is completed, the upper pressure plate 235 can be rotated at a certain angle, which facilitates the gripping operation of the robot arm assembly 3.

[0084] For more details, please see Figure 4As shown, the lower pressure plate 233 includes a first support plate 2331 and a lower pressure head 2332. One end of the first support plate 2331 is horizontally connected to the top surface of the three-axis cylinder 224. The lower pressure head 2332 is installed at the measuring hole of the first support plate 2331. The three-axis cylinder 224 is adapted to drive the first support plate 2331 to move up and down, so as to move the lower pressure head 2332 to the top center position of the measuring sleeve 232. This improves the pressing stability of the gear 6 under test, which is beneficial to improving the detection accuracy of the measuring head 234, and the operating noise is low.

[0085] Further, please refer to Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the pushing mechanism 42 includes a cylinder support 421, a second drive cylinder 422, and a third drive cylinder 423, wherein:

[0086] The cylinder bracket 421 is connected to the upper surface of the pusher base plate 41 and is used to support and install the second drive cylinder 422 and the third drive cylinder 423. The second drive cylinder 422 is horizontally mounted on the cylinder bracket 421, and the third drive cylinder 423 is connected to the upper surface of the pusher base plate 41. The output shaft of the second drive cylinder 422 is provided with a gear push block 4221, and the output shaft of the third drive cylinder 423 is provided with an upper push plate 4231. The upper push plate 4231 is provided with a V-shaped groove on the side near the material trough mechanism 43. The V-shaped groove is suitable for accommodating the gear 6 to be tested. The lower end of the gear push block 4221 is suitable for matching the outer circumference of the gear 6 to be tested.

[0087] When the robotic arm assembly 3 horizontally grips the gear 6 to be tested and places it on the inlet side of the trough mechanism 43, the second drive cylinder 422 and the third drive cylinder 423 push the gear 6 to be tested from a horizontal state to a vertical state. The bottom of the gear 6 to be tested is adapted to the shape of the V-shaped groove of the trough mechanism 43, so that the gear 6 to be tested can be smoothly guided into the V-shaped groove.

[0088] For details, please refer to Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the material trough mechanism 43 includes multiple material troughs 431 horizontally mounted on the pusher base plate 41, a baffle frame 432 horizontally spanning above the material troughs 431, and a guide structure 433. The guide structure 433 includes a guide handle 4331, a guide rod 4332, and a rear positioning plate 4333. One end of the guide handle 4331 is fixedly connected to the rear positioning plate 4333, and the other end is fixedly connected to the guide rod 4332.

[0089] Thus, the number of material troughs 431 is matched with the classification standard of the gears 6 being tested. The number of different levels corresponds to the number of material troughs 431. The baffle frame 432 is used to limit the final number of gears 6 being tested when the second drive cylinder 422 pushes the gears 6 being tested onto the guide rod 4332, based on the length of the guide rod 4332 and the number of gears 6 being tested on the guide rod 4332.

[0090] Further, please refer to Figure 8 and Figure 9 As shown, the storage component 4 also includes a placement bracket 44 and a retraction limit seat 45 that are vertically connected to one end face of the material tank 431. The placement bracket 44 has a through hole facing the material tank 431, and the retraction limit seat 45 is suitable for placing the gear 6 to be tested that is horizontally gripped by the robot arm component 3.

[0091] In this embodiment, the placement bracket 44 is located at the inlet end of the material tank 431, and a matching through hole is provided on the placement bracket 44 directly opposite the material tank 431, allowing the gear 6 to be tested to be pushed into the material tank 431 through the through hole. The retraction limit seat 45 is used to place the tested gear 6 that has been gripped by the robotic arm assembly 3. Since the robotic arm assembly 3 has three degrees of freedom in the X, Y, and Z axes, the gripped gear 6 is placed horizontally on the retraction limit seat 45.

[0092] Specifically, please refer to Figure 10 As shown, the robotic arm assembly 3 includes a three-axis robotic arm 31 and a gripper structure 32. The gripper structure 32 is mounted on the three-axis robotic arm 31. The gripper structure 32 consists of a chuck 322 and a gripper 321. The top of the gripper 321 is mounted on the chuck 322 and can be adjusted according to the outer diameter of the gear 6 being measured.

[0093] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
