[0015] In this invention, the auxiliary fixture in the press-fit assembly can support the dust cover. Operators only need to place the dust cover on the auxiliary fixture, eliminating the need for complex installation operations by directly holding the dust cover. This significantly improves the convenience and efficiency of installation, especially in mass production, effectively reducing the labor intensity and operation time of operators. Simultaneously, the press-fit mechanism in the press-fit assembly can drive the auxiliary fixture towards the drive shaft, realizing an automated dust cover installation process. Compared to traditional manual operation, automated installation is not limited by the operator's skill level or physical strength, maintaining a stable installation speed and force, improving installation consistency and reliability, and meeting the needs of high-efficiency production.

[0016] In this invention, the design of the positioning rod abutting against the end of the drive shaft provides a precise positioning reference for the installation of the dust cover, improving the stability of the drive shaft during press-fitting. The auxiliary tooling is movably fitted onto the positioning rod. Driven by the press-fitting mechanism, the auxiliary tooling moves towards the drive shaft along the axial direction of the positioning rod. The positioning rod acts as a guide, ensuring the straightness of the auxiliary tooling during movement, allowing the dust cover to be accurately fitted onto the drive shaft, thereby improving product quality.

[0017] In this invention, the stability of the drive shaft during dust cover installation is improved by setting positioning components; when multiple positioning components are used, the drive shaft can be kept in a stable position during the pressing process, so as to avoid inaccurate dust cover installation due to drive shaft shaking or displacement, thereby improving installation quality.

[0018] In this invention, the positioning cylinder can move the positioning rod closer to or further away from the end of the drive shaft; compared with the traditional manual adjustment, positioning is more convenient, and it is also easier to remove the drive shaft after installation.

[0019] In this invention, a press-fit cylinder is used as the power source for press-fitting the dust cover, which can stably output and precisely control the force, ensuring the stability and accuracy of the dust cover press-fitting process. At the same time, the speed and stroke of the auxiliary tooling approaching the drive shaft can be precisely controlled by adjusting the press-fit cylinder to meet the installation requirements of dust covers and drive shafts of different specifications.

[0020] In this invention, since the positioning rod is fixed on the positioning bracket and the pressing assembly is also assembled 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.

[0021] In this invention, the tooling through hole and the positioning rod cooperate to provide precise guidance for the auxiliary tooling during the pressing process; this allows the auxiliary tooling to move stably along the axial direction of the positioning rod, minimizing the risk of the auxiliary tooling shifting during movement, thereby improving the positional accuracy of the dust cover installation.

[0022] In this invention, the diameter of the through hole of the tooling is greater than or equal to the diameter of the drive shaft and the positioning rod; thus, when the pressing cylinder pushes the push plate and the auxiliary tooling to move, the auxiliary tooling can transition from the positioning rod to the drive shaft, thereby driving the dust cover to the drive shaft and realizing the pressing of the dust cover.

[0023] In this invention, the supporting part is in the shape of an annular step and matches the internal space of the dust cover. This design allows the dust cover to be accurately fitted onto the supporting part.

[0024] 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 the replacement of 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. This greatly improves the adaptability of the equipment to different production needs and enhances its versatility.

[0025] In this invention, the positioning rod passes through the push plate and 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 push plate's movement to move the auxiliary tooling for pressing 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.

[0026] In this invention, by cooperating with the detection rod and the detection device in the clamp detection mechanism, the length of the detection rod's moving path can be used to detect whether the clamp is pre-installed and whether it is pre-installed in place; thus facilitating the subsequent tightening of the clamp; improving assembly efficiency and reducing product error rate.

[0027] 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.

[0028] 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 positioned on the moving path of the top 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 lowers the mounting block 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, indicating that the clamp pre-installation is qualified; if the dust cover does not have a pre-installed clamp 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.

[0029] In this invention, when the top of the detection rod abuts against the trigger detection device, the limiting rod abuts against the top of the limiting space; when the bottom of the detection rod does not contact other objects, the limiting rod abuts against the bottom of the limiting space, thereby preventing the detection rod from falling out of the installation space.

[0030] In this invention, the detachable and replaceable detection rod allows the device to be replaced according to different clamp models, making the device more widely applicable. Attached Figure Description

[0044] like Figure 1-9As shown, a dust cover press-fit module is used to install a dust cover 103 onto a drive shaft 101. This device includes a press-fit assembly 1 and a positioning assembly 2. The positioning assembly 2 includes a positioning rod 21 that abuts against the end of the drive shaft 101, the positioning rod 21 corresponding to the axial direction of the drive shaft 101. The press-fit assembly 1 includes an auxiliary tooling 11 that can support the dust cover 103, the auxiliary tooling 11 being movably sleeved on the positioning rod 21. The press-fit assembly 1 also includes a press-fit mechanism 12 that drives the auxiliary tooling 11 toward the drive shaft 101. The auxiliary tooling 11 in the press-fit assembly 1 can support the dust cover 103. Operators only need to place the dust cover 103 on the auxiliary tooling 11, eliminating the need for complex installation operations by directly holding the dust cover 103, greatly improving the convenience and efficiency of installation. Especially in mass production, it can effectively reduce the labor intensity and operation time of operators. Meanwhile, the pressing mechanism 12 in the pressing assembly 1 can drive the auxiliary tooling 11 to move towards the drive shaft 101, realizing the automated installation process of the dust cover 103. Compared with the traditional manual operation method, automated installation is not limited by the operator's skill level and physical strength, can maintain a stable installation speed and force, improve the consistency and reliability of installation, and also meet the needs of high-efficiency production.

[0045] In this invention, the design of the positioning rod 21 abutting against the end of the drive shaft 101 provides a precise positioning reference for the installation of the dust cover 103, improving the stability of the drive shaft 101 during press-fitting. The auxiliary tooling 11 is movably fitted onto the positioning rod 21. Driven by the press-fitting mechanism 12, the auxiliary tooling 11 moves towards the drive shaft 101 along the axial direction of the positioning rod 21. The positioning rod 21 acts as a guide, ensuring the straightness of the auxiliary tooling 11 during movement, so that the dust cover 103 can be accurately fitted onto the drive shaft 101, thereby improving the production quality of the product.

[0046] In this invention, at least one positioning component 2 is provided, corresponding to the end of the drive shaft 101. The positioning component 2 includes a positioning cylinder 22 that moves the positioning rod 21 closer to or further away from the end of the drive shaft 101. The positioning cylinder 22 can move the positioning rod 21 closer to or further away from the end of the drive shaft 101. Compared to traditional manual adjustment, this makes positioning more convenient and also facilitates the removal of the drive shaft 101 after installation. In this invention, the positioning component 2 enhances the stability of the drive shaft 101 during the installation of the dust cover 103. When multiple positioning components 2 are used, the drive shaft 101 can be further kept in a stable position during the pressing process, minimizing the risk of inaccurate installation of the dust cover 103 due to shaking or displacement of the drive shaft 101, thus improving installation quality.

[0047] In this embodiment, the device further includes a tooling base 3 for placing the drive shaft 101; there are two positioning components 2, which are respectively disposed on the left and right sides of the tooling base 3, corresponding to the two ends of the drive shaft 101.

[0048] In this utility model, the pressing mechanism 12 includes a pressing cylinder 13 and a push plate 14 that drive the auxiliary tooling 11 to move toward the transmission shaft 101; the auxiliary tooling 11 is mounted on the push plate 14, and the pressing cylinder 13 cooperates with the push plate 14 to drive the push plate 14 and the auxiliary tooling 11 to move closer to or away from the transmission shaft 101.

[0049] In this invention, the positioning component 2 includes a positioning bracket 23, with the positioning rod 21 mounted on the positioning bracket 23. A positioning cylinder 22 cooperates with the positioning bracket 23 and drives its movement. The pressing cylinder 13 is fixed on the positioning bracket 23, and the piston rod of the pressing cylinder 13 is connected to the push plate 14. In this invention, the pressing cylinder 13 serves as the power source for pressing the dust cover 103, enabling stable output and precise control of the force. This ensures the stability and accuracy of the pressing process of the dust cover 103. Furthermore, the speed and stroke of the auxiliary tooling 11 approaching the drive shaft 101 can be precisely controlled by adjusting the pressing cylinder 13 to meet the installation requirements of dust covers 103 and drive shafts 101 of different specifications.

[0050] In this utility model, since the positioning rod 21 is fixed on the positioning bracket 23 and the pressing assembly 1 is also assembled on the positioning bracket 23, when the positioning cylinder 22 pushes the positioning rod 21 on the positioning bracket 23 to abut the end of the transmission shaft 101, the push plate 14 also moves towards the transmission shaft 101 in sync, thereby improving the overall assembly efficiency of the equipment.

[0051] In this embodiment, a length detection mechanism 4 is included to confirm the condition of the drive shaft 101. The length detection mechanism 4 includes a displacement sensor 41 for detecting the movement distance of the positioning rod 21. The device includes a platform 5, and the positioning assembly 2 includes a positioning mounting plate 24, which is mounted on the platform 5. The positioning bracket 23 is movably mounted on the positioning mounting plate 24 through the cooperation of a slide rail and a slider. The displacement sensor 41 is a grating ruler, which is mounted on the positioning mounting plate 24 and cooperates with the positioning bracket 23, thereby facilitating the detection of the movement distance of the positioning rod 21. In this utility model, since the positioning rod 21 abuts against the end of the drive shaft 101, its movement distance is directly related to the length of the drive shaft 101. Therefore, the movement distance of the positioning rod 21 can be detected by the displacement sensor 41 to determine whether the length of the drive shaft 101 meets the requirements for pressing the dust cover 103. This allows the device to not only be applicable to the pressing of dust covers 103 for different models of drive shafts 101, but also to reduce pressing errors caused by incorrect models through the setting of the length detection mechanism 4.

[0052] In this utility model, the auxiliary tooling 11 is provided with tooling through holes 111 through which the positioning rod 21 passes. Through the cooperation between the tooling through holes 111 and the positioning rod 21, the auxiliary tooling 11 is provided with precise guidance during the pressing process. This allows the auxiliary tooling 11 to move stably along the axial direction of the positioning rod 21, and avoids the auxiliary tooling 11 from shifting during the movement as much as possible, thereby improving the positional accuracy of the dust cover 103 installation.

[0053] In this invention, 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 21; thus, when the pressing cylinder 13 pushes the push plate 14 and the auxiliary tooling 11 to move, the auxiliary tooling 11 can transition from the positioning rod 21 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.

[0054] In this utility model, the auxiliary tooling 11 includes a support part 112, which is located at one end of the auxiliary tooling 11 facing the drive shaft 101. The support part 112 is in the shape of an annular step and matches the internal space of the dust cover 103. The dust cover 103 is detachably fitted onto the support part 112. The design of the support part 112 being in the shape of an annular step and matching the internal space of the dust cover 103 enables the dust cover 103 to be accurately fitted onto the support part 112.

[0055] In this invention, the auxiliary tooling 11 is detachably mounted on the push plate 14, and the push plate 14 has an assembly space 141 for assembling the auxiliary tooling 11. The auxiliary tooling 11 also includes an assembly part 113, which is located at the end of the auxiliary tooling 11 away from the drive shaft 101. The assembly part 113 has an assembly groove 114 arranged circumferentially along the auxiliary tooling 11. The push plate 14 has an assembly hole 142 communicating with the assembly space 141. The push plate 14 also has an assembly rod 143 that is threaded into the assembly hole 142 and can extend into the assembly space 141. When the assembly part 113 is in the assembly space 141, the assembly groove 114 is on the movement path of the assembly rod 143. The assembly rod 143 is screwed in so that its end is in the assembly groove 114, thereby realizing the assembly of the auxiliary tooling 11. The surface of the push plate 14 facing the drive shaft 101 is provided with an assembly opening 144 for the assembly part 113 to enter the assembly space 141; the surface of the push plate 14 facing the positioning bracket 23 is also provided with a through hole 145 communicating with the assembly space 141, and the positioning rod 21 passes through the through hole 145 and the tooling through hole 111 to abut 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 push plate 14 driving the auxiliary tooling 11 to move for pressing the dust cover 103; thus, 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.

[0056] In this invention, the auxiliary tooling 11 is detachably mounted on the push plate 14, enabling 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, the original auxiliary tooling 11 can be removed from the push plate 14 and a new matching auxiliary tooling 11 can be installed to achieve accurate pressing of the dust cover 103. Combined with the length detection mechanism 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.

[0057] In this embodiment, the inner diameter of the assembly opening 144 is larger than the inner diameter of the through hole 145, and the inner diameter of the assembly opening 144 corresponds to the inner diameter of the assembly space 141, which makes it more convenient to install the auxiliary tooling 11.

[0058] This utility model also includes a clamp detection mechanism 6, which includes a detection rod 61, a detection device 62, a detection mounting plate 63, a horizontal adjustment device 64, and a vertical adjustment device 65. The detection mounting plate 63 is fixedly connected to the push plate 14, and the horizontal adjustment device 64 is mounted on the detection mounting plate 63. The horizontal adjustment device 64 includes a horizontal movable part, and the vertical adjustment device 65 is fixed on the horizontal movable part. The vertical adjustment device 65 includes a vertical movable part, and a mounting block 66 is provided on the vertical movable part. The detection rod 61 is movably mounted on the mounting block 66. The detection device 62 is fixed on the mounting block 66 and is located on the movement path of the detection rod 61. In this embodiment, the horizontal adjustment device 64 is a cylinder, and its horizontal movable part is its cylinder piston; the vertical adjustment device 65 is a slide, and its vertical movement is its slide movable block.

[0059] In this embodiment, the pressing mechanism 12 further includes a guide rod 15 and an assembly plate 16; a bearing is provided on the positioning bracket 23, and the guide rod 15 cooperates with the bearing; both ends of the guide rod 15 are fixedly connected to the push plate 14 and the assembly plate 16 respectively; thereby improving the movement stability of the push plate 14. The front and rear ends of the detection mounting plate 63 are fixed to the push plate 14 and the assembly plate 16 respectively, further improving the installation stability of the detection mounting plate.

[0060] In this invention, the detection rod 61 and the detection device 62 in the clamp detection mechanism 6 cooperate to detect whether the clamp 102 is pre-installed and whether it is pre-installed in place, based on the length of the movement path of the detection rod 61. This facilitates the subsequent tightening of the clamp 102, improves assembly efficiency, and reduces product error rate. It is worth noting that the clamp 102 is provided with a tightening part. After the clamp 102 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 clamping by the clamp 102 clamp and also facilitates the detection rod 61 in detecting whether the clamp 102 is pre-installed and whether it is pre-installed in place.

[0061] In this utility model, the clamp detection mechanism 6 is adjusted by a combination of horizontal adjustment device 64 and vertical adjustment device 65, which can ensure that the detection rod 61 accurately points to the clamp 102, avoid detection errors caused by detection position deviation, and greatly improve the detection accuracy; and can adapt to the clamp 102 detection needs of various dust covers 103 of different specifications to the greatest extent.

[0062] In this invention, a vertically arranged mounting space 661 is provided within the mounting block 66, and the detection rod 61 is movably disposed within the mounting space 661. An exposure hole 662 is provided at the bottom of the mounting block 66, through which the bottom end of the detection rod 61 protrudes and faces the area where the dust cover 103 is pre-installed with the clamp 102 on the auxiliary tooling 11. The detection device 62 is located on the movement path of the top end of the detection rod 61. The exposure hole 662 at the bottom of the mounting block 66 ensures that the bottom end of the detection rod 61 accurately faces the area where the dust cover 103 is pre-installed with the clamp 102 on the auxiliary tooling 11. Furthermore, the fact that the detection device 62 is located on the movement path of the top end of the detection rod 61 makes it possible for the detection rod 61 to touch the detection device 62 a condition for evaluating the pre-installation qualification of the clamp 102. When the vertical adjustment device 65 lowers the mounting block 66 to approach the clamp 102, the detection rod 61 will first abut against the clamp 102. Due to the obstruction of the clamp 102, the detection rod 61 will rise relative to the mounting block 66, thereby abutting against and triggering the detection device 62, 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 61 cannot rise relative to the mounting block 66, or even if the detection rod 61 can rise relative to the mounting block 66, it cannot reach the level of triggering the detection device 62.

[0063] 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.

[0064] In this invention, a horizontally positioned limiting space 663 is also provided within the mounting block 66, which communicates with the mounting space 661. A limiting rod 67 is provided on the detection rod 61, which is located within the limiting space 663 and moves with the detection rod 61. The detection rod 61 and the limiting rod 67 are combined in a cross shape. When the top of the detection rod 61 abuts against the trigger detection device 62, the limiting rod 67 abuts against the top of the limiting space 663. When the bottom of the detection rod 61 is not in contact with any other object, the limiting rod 67 abuts against the bottom of the limiting space 663, thereby preventing the detection rod 61 from falling out of the mounting space 661.

[0065] In this invention, the detection rod 61 is detachably and replaceably assembled within the installation space 661; the limiting space 663 communicates with the outside, and the detection rod 61 is provided with a limiting through hole arranged radially thereon. The limiting rod 67 is detachably passed through the limiting through hole and fixed by a snap ring; the detachable and replaceable detection rod 61 allows the device to replace the detection rod 61 according to different clamp 102 models, making the device more widely applicable.

[0066] In this embodiment, the top end of the detection rod 61 is the trigger end 611, and the bottom end of the detection rod 61 is the contact end 612. The diameter of the trigger end 611 is smaller than the diameter of the contact end 612. A spring 68 is sleeved on the trigger end 611, and the two ends of the spring 68 abut against the inner wall of the mounting space 661 and the contact end 612, respectively. Under the action of the spring 68, the detection rod 61 is always exposed from the exposure hole 662 before contacting the surface of the clamp 102 or the surface of the dust cover 103. After the detection rod 61 moves to trigger the detection device 62, it can be reset and exposed from the exposure hole 662 under the action of the spring 68.

[0067] The operating procedure for this equipment is as follows: 1. According to the requirements of this pressing work, assemble the corresponding auxiliary tooling 11 onto the push plate 14; use manual labor or a robotic arm to install the dust cover 103 onto the auxiliary tooling 11 and pre-install the clamp 102; use manual labor or a robotic arm to place the drive shaft 101 onto the tooling seat 3.

[0068] 2. The horizontal adjustment device 64 and the vertical adjustment device 65 of the clamp detection mechanism 6 work to make the detection rod 61 accurately point to the clamp 102, and the detection rod 61 cooperates with the detection device 62 to detect whether the clamp 102 is pre-installed and whether it is pre-installed in place.

[0069] 3. After the clamp inspection mechanism 6 detects that the clamp 102 is in good condition, the positioning cylinders 22 of the positioning components 2 on the left and right sides of the tooling base 3 work to push the positioning brackets 23 of the two respectively, so that the positioning rods 21 of the two abut against the two ends of the transmission shaft 101; and the length of the transmission shaft 101 is confirmed again by the length inspection mechanism 4.

[0070] 4. After the length detection mechanism 4 confirms that there is no error, the pressing cylinder 13 drives the push plate 14 and the auxiliary tooling 11 on the push plate 14 to move, thereby pressing the dust cover 103 on the auxiliary tooling 11 onto the drive shaft 101.

[0071] 5. The operator then performs the subsequent clamping process using clamp 102.

[0072] 6. After clamping by clamp 102, pressing cylinder 13 drives push plate 14 and auxiliary tooling 11 on push plate 14 to reset, positioning cylinder 22 works to drive positioning bracket 23 to reset; the drive shaft 101 is removed from tooling seat 3 by manual labor or mechanical arm.

[0073] It is worth noting that the other technical solutions of this utility model are all existing technologies, and therefore will not be described in detail.

[0074] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the concept of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
