Description

Technical Field

[0001] This invention relates to the field of industrial automation equipment design, and more specifically, to an automated dust cover press-fitting and testing device and its operation method. Background Technology

[0002] In many fields such as automobiles and machinery, the driveshaft is a key transmission component, and its performance and service life directly affect the operation of the entire equipment. The dust cover, as an important component protecting the driveshaft from external factors such as dust and moisture, is crucial to its installation quality.

[0003] Traditional dust cover press-fitting is mostly done manually. Operators need to manually slip the dust cover onto the drive shaft and then use simple tools to ensure a tight fit. However, the speed of manual operation is limited by the operator's skill level and physical strength, making it difficult to meet the demands of high-efficiency production in mass production.

[0004] With increasing production demands, simple mechanical pressing equipment has gradually been applied to dust cover pressing. These simple mechanical pressing devices typically only perform basic pressing actions and lack the ability to detect and monitor the installation process of the drive shaft and dust cover. They cannot confirm the correct specifications and orientation of the drive shaft before pressing, nor can they check if the clamps are pre-installed. This means that operators still need to confirm various pressing conditions during the pressing process. This not only increases labor costs but also easily leads to operational errors due to human factors, reducing production efficiency and product quality. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides an automated dust cover press-fitting and testing equipment and its operation method that is simple in structure, reasonable in design, more efficient in production, higher in product quality, and reduces labor costs.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: An automated dust cover press-fitting and testing device includes a press-fitting module, a positioning component, a conveying module, a clamping module, and a mistake-proofing module; its operation specifically includes the following steps: S1: Install the auxiliary tooling of the pressing module onto the pressing mechanism of the pressing module, install the dust cover onto the auxiliary tooling, and then pre-install the clamps onto the dust cover; S2: Place the drive shaft on the tooling stand of the transport module; the weighing mechanism of the error prevention module weighs the tooling stand and determines whether there is a drive shaft and whether the model of the drive shaft is correct based on the weight. S3: After the weighing mechanism confirms that the weight is correct, the conveying mechanism of the conveying module drives the tooling seat and the drive shaft on the tooling seat to the location of the pressing module and positioning component. S4: The clamp detection mechanism of the error prevention module detects whether the dust cover on the auxiliary tooling has pre-installed clamps and whether the clamps are correctly pre-installed; S5: After the clamp inspection mechanism confirms that the clamp is correct, the left and right positioning mechanisms of the positioning assembly work. The positioning cylinders of the left and right positioning mechanisms drive the positioning rods of the left and right positioning mechanisms to abut against the two ends of the transmission shaft respectively; and the length of the transmission shaft is confirmed by the length detection mechanism of the error prevention module. S6: The orientation confirmation mechanism of the error prevention module scans and identifies the drive shaft on the tooling base to determine whether there is a drive shaft and whether the direction of the drive shaft is correct. S7: After the length detection mechanism and the direction confirmation mechanism confirm that the drive shaft is correct, the pressing mechanism drives the auxiliary tooling to move, and then presses the dust cover on the auxiliary tooling onto the drive shaft. S8: The operator uses the electronic clamping pliers of the clamping module to clamp the snap ring; S9: The force sensor of the error prevention module detects the clamping force of the electronic clamp caliper, and the position sensor of the error prevention module detects the position of the electronic clamp caliper; S10: After the force sensor and position sensor do not report any errors, the pressing mechanism drives the auxiliary tooling to reset, the positioning cylinder drives the positioning rods of the left and right positioning mechanisms to reset, and the conveying mechanism drives the tooling seat to reset; the drive shaft is then removed from the tooling seat.

Beneficial effects

[0016] In this invention, the entire operation process is automatically completed by each module of the equipment, reducing the time and steps of manual operation, achieving continuous and rapid production, greatly improving production efficiency, and meeting the needs of mass production; it also reduces the number of operators, thereby lowering the company's labor costs. During operation, multiple inspection steps are performed in parallel with other operations; through these inspections, pressing failures or product quality degradation caused by problems such as incorrect drive shaft specifications or direction, or improper pre-installation of clamps are avoided, thus improving the product qualification rate.

[0017] In this invention, the positioning rod passes through the auxiliary tooling and abuts against the end of the drive shaft. This design not only applies a limiting force to the drive shaft, but also does not affect the auxiliary tooling's pressing of the dust cover. As a result, during the pressing of the dust cover, a stable force can be continuously applied to the drive shaft, improving the stability of the dust cover during pressing.

[0018] In this invention, the auxiliary tooling is detachably mounted on the push plate, enabling the equipment to quickly replace the corresponding auxiliary tooling according to different models and specifications of dust covers. When production requires changing to dust covers of different sizes or shapes, simply remove the original auxiliary tooling from the push plate and install the matching new auxiliary tooling to achieve accurate pressing of the dust cover. Combined with the length detection mechanism to confirm the model of the drive shaft, the adaptability of this equipment to different production needs is greatly improved, and the versatility of this equipment is enhanced.

[0019] In this invention, since the positioning rod is fixed on the positioning bracket and the pressing mechanism is also mounted on the positioning bracket, when the positioning cylinder pushes the positioning rod on the positioning bracket to abut the end of the transmission shaft, the push plate also moves toward the transmission shaft in sync, thereby improving the overall assembly efficiency of the equipment.

[0020] In modern production, enterprises often need to quickly switch between producing different models of equipment according to market demands, and the drive shaft lengths of different models of equipment vary. In this invention, since the positioning rod abuts against both ends of the drive shaft, its movement distance is directly related to the length of the drive shaft; therefore, the movement distance of the positioning rod can be detected by a displacement sensor to determine whether the length of the drive shaft meets the current requirements for dust cover pressing; thus, this equipment can not only be used for pressing dust covers for different models of drive shafts, but also reduce pressing errors caused by model switching through the length detection mechanism.

[0021] In this invention, the clamp detection mechanism, through the combination of horizontal and vertical adjustment devices, ensures that the detection rod accurately points to the clamp, avoiding detection errors caused by detection position deviations and greatly improving detection accuracy; and it can adapt to the clamp detection needs of various dust covers of different specifications to the greatest extent.

[0022] In this invention, the exposed hole at the bottom of the mounting block allows the bottom of the detection rod to accurately face the area where the dust cover pre-installed clamp is located on the auxiliary fixture; and the detection device is located on the movement path of the detection rod, making whether the detection rod can touch the detection device a condition for evaluating the pre-installation qualification of the clamp. When the vertical adjustment device drives the mounting block to fall close to the clamp, the detection rod will first abut against the clamp, and due to the obstruction of the clamp, the detection rod will rise relative to the mounting block, thereby abutting against and triggering the detection device to indicate that the clamp pre-installation is qualified; if there is no pre-installed clamp on the dust cover or the clamp is not pre-installed properly, the detection rod cannot rise relative to the mounting block, or even if the detection rod can rise relative to the mounting block, it cannot reach the level of triggering the detection device.

[0023] In some cases, different dust covers of different specifications need to be installed at both ends of the drive shaft, which requires distinguishing the direction of the drive shaft and the specifications of the dust cover during installation. In this invention, at least one end of the drive shaft is provided with a confirmation mark, and the vision camera of the direction confirmation mechanism faces one end of the drive shaft. By identifying whether there is a confirmation mark, it can be confirmed whether the drive shaft is in place and whether the installation direction of the drive shaft is correct, thereby reducing the possibility of errors during the press-fitting of the dust cover.

[0024] In this invention, a weighing sensor is fixed to a first transport mounting plate, and a second transport mounting plate is fixed to the weighing sensor; this allows the weight of the drive shaft placed in the tooling seat on the second transport mounting plate to be accurately measured, thereby determining the current model of the drive shaft based on its weight.

[0025] In this invention, the second transport mounting plate is provided with a movable groove, and the bottom of the tooling base is provided with an adjusting block, which is movably mounted in the movable groove; so that the tooling base can be adjusted in the horizontal direction to adapt to drive shafts of different specifications and sizes.

[0026] In this invention, the combined design of the horizontal and vertical adjustment mechanisms enables the electronic clamp pliers to precisely move to the designated position of the clamp on the dust cover for clamping, greatly improving the reliability of clamp installation. A force sensor is installed on the electronic clamp pliers to detect the clamping force, allowing for real-time and accurate measurement of the force applied by the pliers during clamping. This enables precise control of the clamping force; when the clamping force reaches the set value, the system automatically stops the clamping action to prevent damage to the dust cover or clamp due to excessive clamping force, while also avoiding the problem of clamp loosening due to insufficient clamping force. A position sensor monitors the position information of the electronic clamp pliers in real time; if the position of the electronic clamp pliers becomes abnormal and deviates from the preset pressing position, the position sensor immediately feeds a signal back to the control system, which promptly issues an alarm and stops the equipment operation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0044] like Figure 1-13 As shown, an automated dust cover press-fitting and testing device and its operation method are disclosed. This device is used for installing a dust cover 103 on a drive shaft 101. The dust cover 103 is installed on the drive shaft 101 by a clamp 102. The automated dust cover press-fitting and testing device includes a press-fitting module 1, a conveying module 2, and a fault-prevention module 3. The conveying module 2 includes a tooling seat 21 for placing the drive shaft 101 and a conveying mechanism 22 for moving the tooling seat 21. The press-fitting module 1 includes an auxiliary tooling 11 for supporting the dust cover 103 and a press-fitting mechanism 12 for moving the auxiliary tooling 11 toward the tooling seat 21, thereby press-fitting the dust cover 103 onto the drive shaft 101. This automated operation eliminates the limitations of manual operation speed due to skill level and physical strength. In mass production, it can quickly and continuously complete the installation of the dust cover 103, significantly improving production efficiency while reducing labor costs and meeting the needs of high-efficiency production. The error prevention module 3 includes a weighing mechanism 31 for confirming the condition of the drive shaft 101 and a direction confirmation mechanism 32. The weighing mechanism 31 includes a weighing sensor 311 disposed below the tooling base 21. At least one end of the drive shaft 101 is provided with a confirmation mark. The direction confirmation mechanism 32 includes a vision camera 321, which faces the end of the drive shaft 101. The error prevention module 3 also includes a clamp detection mechanism 33 for confirming the condition of the clamp 102. The clamp detection mechanism 33 includes a movable detection rod 330 and a detection device 331 that cooperates with the detection rod 330. Through multiple error prevention detections, errors can be detected and corrected in a timely manner during the production process, greatly reducing the possibility of product errors during the pressing process and improving the production quality of the product.

[0045] In this invention, the weighing mechanism 31 of the error prevention module 3 can weigh the drive shaft 101 before pressing by a weighing sensor 311 set below the tooling base 21. The weight information is used to determine whether the drive shaft 101 is installed and whether the specifications of the drive shaft 101 are correct, thus preventing production errors caused by using a drive shaft 101 with incorrect specifications.

[0046] In some cases, dust covers 103 of different specifications need to be installed at both ends of the drive shaft 101. Therefore, it is necessary to distinguish the direction of the drive shaft 101 and the specifications of the dust cover 103 when installing the dust cover 103. In this invention, at least one end of the drive shaft 101 is provided with a confirmation mark. The vision camera 321 of the direction confirmation mechanism 32 faces one end of the drive shaft 101. By identifying whether there is a confirmation mark, it can confirm whether the drive shaft 101 is in place and whether the installation direction of the drive shaft 101 is correct, thereby reducing the possibility of errors during the pressing process of the dust cover 103.

[0047] In this embodiment, a confirmation mark is provided at one end of the drive shaft 101, and the vision camera 321 faces the end of the drive shaft 101 without the confirmation mark. After the vision camera 321 identifies the presence of the drive shaft 101 on the tooling base 21, it determines the orientation of the drive shaft 101 by scanning for the presence or absence of the confirmation mark. In this embodiment, the correct state is defined as the vision camera 321 not scanning the confirmation mark. In other embodiments, the correct state can be defined as the vision camera 321 scanning the confirmation mark; or multiple vision cameras 321 can be used to confirm the confirmation marks at both ends of the drive shaft 101, etc.

[0048] In this invention, through the cooperation between the detection rod 330 and the detection device 331 in the clamp detection mechanism 33, the length of the movement path of the detection rod 330 can be used to detect whether the clamp 102 is pre-installed and whether it is pre-installed in place. This facilitates the subsequent tightening of the clamp 102 by the electronic clamp clamp 54, improving assembly efficiency and reducing product error rate. It is worth noting that the clamp 102 is provided with a tightening part. After the electronic clamp clamp 54 clamps the tightening part, the entire clamp 102 is tightened to fix the dust cover 103. During the operation of this equipment, the tightening part of the clamp 102 is required to face upwards, which facilitates the clamping by the electronic clamp clamp 54 and also facilitates the detection rod 330 to detect whether the clamp 102 is pre-installed and whether it is pre-installed in place.

[0049] In this invention, the automated dust cover press-fitting and testing equipment includes a positioning component 4, which includes a left positioning mechanism 41 and a right positioning mechanism 42. The transport module 2 is disposed between the left positioning mechanism 41 and the right positioning mechanism 42. Both the left positioning mechanism 41 and the right positioning mechanism 42 include a positioning rod 43 and a positioning cylinder 44 that pushes the positioning rod 43 to move. The axial direction of the positioning rod 43 is consistent with the axial direction of the drive shaft 101 on the tooling seat 21. The positioning cylinder 44 drives the positioning rods 43 of the left and right positioning mechanisms 42 to abut against both ends of the drive shaft 101. This precise positioning method can ensure the stable position of the drive shaft 101 during the press-fitting process and avoid axial or radial displacement of the drive shaft 101. This effectively prevents problems such as skewed or loose dust cover 103 installation caused by positional deviation of the drive shaft 101, and improves the installation quality of the dust cover 103.

[0050] In this invention, the error prevention module 3 includes a length detection mechanism 34 for confirming the status of the drive shaft 101. The length detection mechanism 34 includes a displacement sensor 341 for detecting the movement distance of the positioning rod 43. In modern production, enterprises often need to quickly switch between producing different models of equipment according to market demands, and the lengths of the drive shafts 101 vary for different models. In this invention, since the positioning rod 43 abuts against both ends of the drive shaft 101, its movement distance is directly related to the length of the drive shaft 101. Therefore, the displacement sensor 341 can detect the movement distance of the positioning rod 43 to determine whether the length of the drive shaft 101 meets the current requirements for pressing the dust cover 103. This allows the device to not only be applicable to pressing the dust cover 103 of different models of drive shafts 101, but also reduce pressing errors caused by model switching through the length detection mechanism 34.

[0051] In this invention, both the left positioning mechanism 41 and the right positioning mechanism 42 include a positioning bracket 45, and a positioning rod 43 is fixed on the positioning bracket 45; a positioning cylinder 44 cooperates with the positioning bracket 45 and drives the positioning bracket 45 and the positioning rod 43 to move; the pressing module 1 is assembled on the positioning bracket 45; the pressing mechanism 12 includes a pressing cylinder 121 and a push plate 122, the pressing cylinder 121 is fixed on the positioning bracket 45, and the piston rod of the pressing cylinder 121 is connected to the push plate 122, driving the push plate 122 to move; the auxiliary tooling The positioning rod 43 is mounted on the push plate 122. The push plate 122 is located between the positioning bracket 45 and the tooling seat 21. The positioning rod 43 passes through the push plate 122 and the auxiliary tooling 11 and abuts against the end of the drive shaft 101. This design not only applies a limiting force to the drive shaft 101, but also does not affect the movement of the push plate 122 to drive the auxiliary tooling 11 to press the dust cover 103. Therefore, during the pressing of the dust cover 103, a stable force can be continuously applied to the drive shaft 101, improving the stability of the dust cover 103 during pressing. At the same time, since the positioning rod 43 is fixed on the positioning bracket 45, and the pressing mechanism 12 is also mounted on the positioning bracket 45, when the positioning cylinder 44 pushes the positioning rod 43 on the positioning bracket 45 to abut against the end of the drive shaft 101, the push plate 122 also moves towards the drive shaft 101 in sync, thereby improving the overall assembly efficiency of the equipment.

[0052] In this invention, the auxiliary tooling 11 is detachably mounted on the push plate 122, and the push plate 122 has an assembly space 123 for assembling the auxiliary tooling 11. The auxiliary tooling 11 has tooling through holes 111 through which the positioning rod 43 passes, and the positioning rod 43 passes through the tooling through holes 111 and abuts against the end of the drive shaft 101. The auxiliary tooling 11 includes an assembly part 112 and a bearing part 113, which are located at opposite ends of the auxiliary tooling 11. The bearing part 113 is annularly stepped and matches the internal space of the dust cover 103, and the dust cover 103 is detachably fitted onto the bearing part 113. The assembly part 112 is located within the assembly space 123. The assembly part 112 is provided with an assembly groove 114 arranged circumferentially along the auxiliary tooling 11. The push plate 122 is provided with an assembly hole 124 communicating with the assembly space 123. The push plate 122 is also provided with an assembly rod 125 that is threadedly engaged with the assembly hole 124 and can extend into the assembly space 123. When the assembly part 112 is located within the assembly space 123, the assembly groove 114 is located on the movement path of the assembly rod 125. When the assembly part 112 of the auxiliary tooling 11 is located within the assembly space 123, the assembly rod 125 is screwed in so that its end is located within the assembly groove 114, thereby realizing the assembly of the auxiliary tooling 11. The surface of the push plate 122 facing the tooling seat 21 is provided with an assembly opening 126 for the assembly part 112 to enter the assembly space 123; the cylinder arm of the press cylinder 121 is connected to the surface of the push plate 122 facing the positioning bracket 45; the surface of the push plate 122 facing the positioning bracket 45 is also provided with a through hole 127 communicating with the assembly space 123, and the positioning rod 43 passes through the through hole 127 and the tooling through hole 111 and abuts against the end of the drive shaft 101. The auxiliary tooling 11 is detachably mounted on the push plate 122, allowing the equipment to quickly replace the corresponding auxiliary tooling 11 according to different models and specifications of dust covers 103. When production requires the replacement of dust covers 103 of different sizes or shapes, simply remove the original auxiliary tooling 11 from the push plate 122 and install the matching new auxiliary tooling 11 to achieve accurate pressing of the dust cover 103. Combined with the length detection mechanism 34 to confirm the model of the drive shaft 101, the adaptability of this equipment to different production needs is greatly improved, and the versatility of this equipment is enhanced.

[0053] In this embodiment, the inner diameter of the assembly opening 126 is larger than the inner diameter of the through hole 127, and the inner diameter of the assembly opening 126 corresponds to the inner diameter of the assembly space 123, thereby making it more convenient to install the auxiliary tooling 11.

[0054] It is worth noting that the diameter of the tooling through hole 111 is greater than or equal to the diameter of the drive shaft 101 and the positioning rod 43; thus, when the pressing cylinder 121 pushes the push plate 122 and the auxiliary tooling 11 to move, the auxiliary tooling 11 can transition from the positioning rod 43 to the drive shaft 101, thereby driving the dust cover 103 onto the drive shaft 101, and realizing the pressing of the dust cover 103.

[0055] In this embodiment, the center points of the auxiliary tooling 11, tooling through hole 111, assembly opening 126, assembly space 123 and through hole 127 are on the same straight line, which makes the overall structure more stable and can drive the auxiliary tooling 11 to press the dust cover 103 without affecting the application of the limiting force to the drive shaft 101.

[0056] In this invention, the clamp detection mechanism 33 includes a detection mounting plate 332, a horizontal adjustment device 333, and a vertical adjustment device 334. The detection mounting plate 332 is fixedly connected to the push plate 122, and the horizontal adjustment device 333 is mounted on the detection mounting plate 332. The horizontal adjustment device 333 includes a horizontal movable part, and the vertical adjustment device 334 is fixed on the horizontal movable part. The movement paths of the horizontal movable part, the movement paths of the cylinder arm of the pressing cylinder 121, and the movement paths of the cylinder arm of the positioning cylinder 44 are parallel to each other. The vertical adjustment device 334 includes a vertical movable part, on which a mounting block 335 is provided. The detection rod 330 is movably mounted on the mounting block 335, and the detection device 331 is provided on the mounting block 335. The clamp detection mechanism 33, through the combined adjustment of the horizontal adjustment device 333 and the vertical adjustment device 334, ensures that the detection rod 330 accurately points to the clamp 102, avoiding detection errors caused by detection position deviations and greatly improving detection accuracy. Furthermore, it can maximally adapt to the detection needs of clamps 102 on dust covers 103 of various specifications. In this embodiment, the horizontal adjustment device 333 is a cylinder, with its horizontal moving part being the cylinder piston; the vertical adjustment device 334 is a slide table, with its vertical movement being the slide table moving block.

[0057] In this embodiment, the pressing mechanism 12 further includes a guide rod 128 and an assembly plate 129; a bearing is provided on the positioning bracket 45, and the guide rod 128 cooperates with the bearing; both ends of the guide rod 128 are fixedly connected to the push plate 122 and the assembly plate 129 respectively; thereby improving the movement stability of the push plate 122. The front and rear ends of the detection mounting plate 332 are fixed to the push plate 122 and the assembly plate 129 respectively, further improving the installation stability of the detection mounting plate.

[0058] In this invention, a vertically arranged mounting space 336 is provided within the mounting block 335, and the detection rod 330 is movably disposed within the mounting space 336. An exposure hole 337 is provided at the bottom of the mounting block 335, through which the bottom end of the detection rod 330 protrudes and faces the area where the dust cover 103 pre-installs the clamp 102 on the auxiliary tooling 11. The detection device 331 is fixed to the mounting block 335 and is positioned on the movement path of the top end of the detection rod 330. In this invention, the exposure hole 337 at the bottom of the mounting block 335 allows the bottom end of the detection rod 330 to accurately face the area where the dust cover 103 pre-installs the clamp 102 on the auxiliary tooling 11; and the detection device 331 is positioned on the movement path of the detection rod 330, making whether the detection rod 330 can touch the detection device 331 a condition for evaluating the pre-installation qualification of the clamp 102. When the vertical adjustment device 334 drives the mounting block 335 to fall close to the clamp 102, the detection rod 330 will first abut against the clamp 102. Due to the obstruction of the clamp 102, the detection rod 330 will rise relative to the mounting block 335, thereby abutting against and triggering the detection device 331, indicating that the clamp 102 is pre-installed successfully. However, if the clamp 102 is not pre-installed on the dust cover 103 or the clamp 102 is not pre-installed properly, the detection rod 330 cannot rise relative to the mounting block 335, or even if the detection rod 330 can rise relative to the mounting block 335, it cannot reach the level of triggering the detection device 331.

[0059] It is worth noting that the area where the dust cover 103 is pre-installed with the clamp 102 extends beyond the auxiliary tooling 11, so that the dust cover 103 can be firmly installed on the drive shaft 101 after the clamp 102 is tightened.

[0060] In this embodiment, a horizontally positioned limiting space 338 is also provided within the mounting block 335, and the limiting space 338 communicates with the mounting space 336. A limiting rod 339 is provided on the detection rod 330, and the limiting rod 339 is located within the limiting space 338 and moves with the detection rod 330. The detection rod 330 and the limiting rod 339 are combined to form a cross shape. When the top of the detection rod 330 abuts against the trigger detection device 331, the limiting rod 339 abuts against the top of the limiting space 338. When the bottom of the detection rod 330 is not in contact with other objects, the limiting rod 339 abuts against the bottom of the limiting space 338, thereby preventing the detection rod 330 from falling out of the mounting space 336.

[0061] In this embodiment, the detection rod 330 is detachably and replaceably assembled in the installation space 336; the limiting space 338 communicates with the outside, and the detection rod 330 is provided with a limiting through hole arranged radially thereon. The limiting rod 339 is detachably passed through the limiting through hole and fixed by a snap ring; thus, the detection rod 330 can be replaced according to different models of clamps 102, making the applicability of this device more extensive.

[0062] In this embodiment, the top end of the detection rod 330 is the trigger end 330a, and the bottom end of the detection rod 330 is the contact end 330b. The diameter of the trigger end 330a is smaller than the diameter of the contact end 330b. A spring 340 is sleeved on the trigger end 330a, and the two ends of the spring 340 abut against the inner wall of the mounting space 336 and the contact end 330b, respectively. Under the action of the spring 340, the detection rod 330 is always exposed from the exposure hole 337 before contacting the surface of the clamp 102 or the surface of the dust cover 103. After the detection rod 330 moves to trigger the detection device 331, it can be reset and exposed from the exposure hole 337 under the action of the spring 340.

[0063] In this invention, the conveying mechanism 22 includes a conveying motor 221, a first conveying mounting plate 222, and a second conveying mounting plate 223. The conveying motor 221 cooperates with the first conveying mounting plate 222 and drives its movement. The weighing sensor 311 is fixed on the first conveying mounting plate 222, and the second conveying mounting plate 223 is fixed on the weighing sensor 311. The tooling seat 21 is movably mounted on the second conveying mounting plate 223, so that the weight of the drive shaft 101 placed in the tooling seat 21 on the second conveying mounting plate 223 can be accurately measured, and the model of the drive shaft 101 can be determined by the weight of the drive shaft 101. The movement path of the tooling seat 21 intersects with the movement path of the first conveying mounting plate 222. The second conveying mounting plate 223 is provided with a movable groove 224, and the bottom of the tooling seat 21 is provided with an adjusting block 213, which is movably mounted in the movable groove 224. This allows the tooling seat 21 to be adjusted in the horizontal direction to accommodate drive shafts 101 of different specifications and sizes. The tooling base 21 is provided with a placement space 211 for placing the drive shaft 101, and the top of the tooling base 21 is provided with a placement opening 212 for the drive shaft 101 to enter the placement space 211.

[0064] In this embodiment, the length direction of the movable groove 224 is consistent with the axial direction of the transmission shaft 101, and the number of tooling seats 21 is at least two, so that the tooling seats 21 can be adjusted according to the transmission shaft 101 of different lengths to achieve a uniform and stable support effect.

[0065] In this embodiment, the inner diameter of the placement space 211 gradually decreases from the placement opening 212 to the bottom of the placement space 211; the placement space 211 is triangular in shape, thereby achieving a good limiting effect on the drive shaft 101.

[0066] In this invention, the automated dust cover press-fitting and testing equipment includes a clamping module 5 for clamping the clamp 102; the clamping module 5 includes a clamping mounting bracket 51, a horizontal adjustment mechanism 52, a vertical adjustment mechanism 53, and an electronic clamp clamp 54; the horizontal adjustment mechanism 52 is fixed on the clamping mounting bracket 51, and includes a horizontal adjustment plate 521 and a horizontal adjustment part 522 that drives the horizontal adjustment plate 521 to move horizontally; the vertical adjustment mechanism 53 includes a vertical adjustment plate 531, which can be vertically adjusted by the cooperation of a slide rail and a slider. The movable assembly is mounted on the horizontal adjustment plate 521, and the electronic clamp pliers 54 is mounted on the vertical adjustment plate 531. The error prevention module 3 includes a force sensor 35 installed on the electronic clamp pliers 54 to detect the clamping force; the error prevention module 3 also includes a position sensor 36 installed on the electronic clamp pliers 54 to detect the position of the electronic clamp pliers 54. The combined design of the horizontal adjustment mechanism 52 and the vertical adjustment mechanism 53 enables the electronic clamp pliers 54 to move precisely to the designated position of the clamp 102 on the dust cover 103 for clamping, greatly improving the reliability of the clamp 102 installation. The force sensor 35 installed on the electronic clamp pliers 54 can measure the force applied by the electronic clamp pliers 54 when clamping the clamp 102 in real time and accurately; it realizes precise control of the clamping force. When the clamping force reaches the set value, the system automatically stops the clamping action to prevent damage to the dust cover 103 or the clamp 102 due to excessive clamping force, and also avoids the problem of the clamp 102 loosening due to insufficient clamping force. The position sensor 36 can monitor the position information of the electronic clamp 54 in real time. Once the position of the electronic clamp 54 is abnormal and deviates from the preset pressing position, the position sensor 36 will immediately feed the signal back to the control system, and the system will issue an alarm and stop the equipment operation in time.

[0067] In this embodiment, the clamping module 5 also includes an automatic reel 55 that is fixed on the clamping mounting bracket 51. The automatic reel 55 cooperates with the vertical adjustment plate 531 to drive the vertical adjustment plate 531 to reset.

[0068] In this invention, the electronic clamp pliers 54 are detachably mounted on a vertical adjustment plate 531. A mounting base 532 is fixedly mounted on the vertical adjustment plate 531, and the mounting base 532 has a fixing groove. A limit block 533 is detachably mounted at the groove of the mounting base 532, forming a fixed space to fix the position of the electronic clamp pliers 54. The detachable mounting of the electronic clamp pliers 54 on the vertical adjustment plate 531 provides the equipment with extremely high flexibility. In actual production, different models of dust covers 103 may require different specifications or types of electronic clamp pliers 54 for pressing operations. Through the detachable assembly method, operators can quickly and easily replace the electronic clamp pliers 54 to adapt to the pressing requirements of various specifications of dust covers 103. The limit block 533 is also equipped with a control handle 534, a user-friendly design that greatly improves the operator's ease of use.

[0069] In this invention, the automated dust cover press-fit testing equipment includes a control system. The control system is connected to the weighing sensor 311 of the weighing mechanism 31, the vision camera 321 of the direction confirmation mechanism 32, the detection device 331 of the clamp detection mechanism 33, the displacement sensor 341 of the length detection mechanism 34, the force sensor 35 of the electronic clamp clamp 54, and the position sensor 36 of the electronic clamp clamp 54. The control system has different parameters configured for the installation of dust covers 103 on different models of drive shafts 101. When installing a dust cover 103 on a specific model of drive shaft 101, the corresponding parameter can be selected. Through cooperation with the sensors, detection device 331, and vision camera 321, the control system can not only determine whether various components are in place and whether there are any errors during the assembly process, but also further determine whether the selected parameters meet the production conditions by comparing the read parameters. When parameters do not meet the requirements, the control system promptly issues an alarm and stops the equipment, thereby ensuring the quality and stability of each assembly stage and greatly improving the product qualification rate and production efficiency.

[0070] In this embodiment, the detection device 331 adopts a contact switch. When the contact end 330b of the detection rod 330 abuts against the tightening part of the clamp 102, causing the detection rod 330 to rise relative to the mounting block 335, the trigger end 330a of the detection rod 330 triggers the detection device 331.

[0071] In this invention, the automated dust cover pressing and testing equipment also includes a platform 6. The clamping mounting bracket 51, the conveying module 2, and the pressing module 1 are all mounted on the platform 6. The first conveying mounting plate 222 is movably mounted on the platform 6 through the cooperation of a slide rail and a slider. The left positioning mechanism 41 and the right positioning mechanism 42 both include a positioning mounting plate 46, which is mounted on the platform 6. The positioning bracket 45 is movably mounted on the positioning mounting plate 46 through the cooperation of a slide rail and a slider. The displacement sensor 341 is a grating ruler, which is mounted on the positioning mounting plate 46 and cooperates with the positioning bracket 45, thereby facilitating the detection of the movement distance of the positioning rod 43.

[0072] In this embodiment, a slider is provided on the lower surface of the positioning mounting plate 46 of the left positioning mechanism 41, and a slide rail that cooperates with the slider is provided on the platform 6. The positioning mounting plate 46 of the left positioning mechanism 41 moves closer to or further away from the right positioning mechanism 42 through the cooperation of the slide rail and the slider; thereby, the distance between the left positioning mechanism 41 and the right positioning mechanism 42 can be further adjusted, which facilitates the assembly of dust covers 103 on different models of drive shafts 101. Generally, a push cylinder is also provided, which drives the positioning mounting plate 46 of the left positioning mechanism 41 to move.

[0073] In this embodiment, a mounting rod 511 is provided on the clamping mounting bracket 51. The mounting rod 511 is at the horizontal height of the corresponding tooling base 21. The length direction of the mounting rod 511 corresponds to the length direction of the drive shaft 101. The vision camera 321 is mounted on the mounting rod 511 and can be adjusted along the mounting rod 511.

[0074] In this embodiment, the direction confirmation mechanism 32 further includes a visual light source 322 and a light source adjustment cylinder 323. The light source adjustment cylinder 323 is fixed on the platform 6, and the visual light source 322 cooperates with the piston rod of the light source adjustment cylinder 323. The visual light source 322 is set to correspond to the position of the visual camera 321, thereby assisting the visual camera 321 in confirming the confirmation mark of the transmission shaft 101.

[0075] The operating procedure for this equipment is as follows: 1. According to the requirements of this pressing operation, the operator assembles the corresponding auxiliary tooling 11 onto the push plate 122, the electronic clamp 54 onto the vertical adjustment plate 531, and the automatic reel 55 into contact with the vertical adjustment plate 531; adjusts the position of the vision light source 322 on the table panel 6, the position of the vision camera 321 on the mounting rod 511, the position of the tooling base 21 on the second transport mounting plate 223, and the horizontal position of the vertical adjustment plate 531 on the clamping mounting bracket 51; then, selects the installation parameters of the drive shaft 101 and the dust cover 103 in the control system.

[0076] 2. The drive shaft 101 is placed in the placement space 211 of the tooling seat 21 by manual labor or a robotic arm; the dust cover 103 is installed on the auxiliary tooling 11 by manual labor or a robotic arm, and the clamp 102 is pre-installed.

[0077] 3. After the weighing sensor 311 under the tooling base 21 confirms that the weight of the drive shaft 101 is correct, the conveying motor 221 works to send the tooling base 21 and the drive shaft 101 on the tooling base 21 between the left and right positioning mechanisms 42.

[0078] 4. The horizontal adjustment device 333 and the vertical adjustment device 334 of the clamp detection mechanism 33 work to make the detection rod 330 accurately point to the clamp 102, and through the detection rod 330 and the detection device 331, detect whether the clamp 102 is pre-installed and whether it is pre-installed in place.

[0079] 5. After the clamp detection mechanism 33 detects that the clamp 102 is in good condition, the positioning cylinders 44 of the left and right positioning mechanisms 42 work to push the positioning brackets 45 of the two mechanisms respectively, so that the positioning rods 43 on the positioning brackets 45 of the left and right positioning mechanisms 42 abut against the two ends of the transmission shaft 101; and the length of the transmission shaft 101 is confirmed again by the length detection mechanism 34.

[0080] 6. The vision camera 321 and vision light source 322 of the direction confirmation mechanism 32 work to determine the presence or absence of the drive shaft 101 and its direction by recognizing the confirmation mark of the drive shaft 101.

[0081] 7. After the length detection mechanism 34 and the direction confirmation mechanism 32 confirm that there is no error, the pressing cylinder 121 drives the push plate 122 and the auxiliary tooling 11 on the push plate 122 to move, thereby pressing the dust cover 103 on the auxiliary tooling 11 onto the drive shaft 101.

[0082] 8. The operator grips the control handle 534 to move the vertical adjustment plate 531 and the electronic clamp 54 of the vertical adjustment plate 531 toward the clamp 102, and clamps the clamp with the electronic clamp 54.

[0083] 9. When the force sensor 35 and position sensor 36 on the electronic clamp 54 do not report any errors, the automatic reel 55 drives the vertical adjustment plate 531 and the electronic clamp 54 to reset, the pressing cylinder 121 drives the push plate 122 and the auxiliary tooling 11 on the push plate 122 to reset, the positioning cylinders 44 of the left and right positioning mechanisms 42 work to push their positioning brackets 45 to reset respectively, and the conveying motor 221 works to drive the tooling seat 21 to reset; the drive shaft 101 is removed from the tooling seat 21 by manual labor or a robotic arm.

[0084] It is worth noting that the other technical solutions of this invention are all prior art, and therefore will not be described in detail.

[0085] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the concept of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
