Description

Technical Field

[0001] The invention relates to the field of clutch actuator assembly, and in particular to a clutch actuator assembly system and process. Background Art

[0002] Our company has developed a clutch actuator, patent number CN220204636U, as shown in the attached figure of the specification Figure 1 , Figure 2 As shown, the clutch actuator includes a front housing and a rear housing (not shown in the figure), the front housing includes a worm gear chamber and a worm shaft chamber, a fan-shaped worm gear is provided in the worm gear chamber, a worm shaft is provided in the worm shaft chamber, the fan-shaped worm gear and the worm shaft are meshed, the end of the worm shaft is connected to the motor power, and the fan-shaped worm gear is connected to the gearbox power, so as to realize the purpose of controlling the gearbox through the motor, the worm gear and the worm shaft in sequence;

[0003] A connecting arc surface is formed at the connecting position of the worm wheel chamber and the worm shaft chamber, the worm shaft passes through the connecting arc surface and partially extends into the worm wheel chamber, the projection of the connecting arc surface on the bottom of the worm wheel chamber is an arc (that is, the connecting arc surface and the bottom of the worm wheel chamber are perpendicular), and the vertical plane projection of the connecting arc surface on the bottom of the worm wheel chamber is an ellipse; when the shell is placed horizontally, the opening of the worm wheel chamber faces upward, which is convenient for placing the fan-shaped worm wheel, the bottom of the worm wheel chamber is horizontal, and the central axis of the worm shaft is horizontal.

[0004] In order to extend the life of the machinery, a large amount of grease is usually applied to the meshing position of the worm gear, otherwise the later demand for grease cannot be met. However, a large amount of grease is not conducive to cost control on the one hand, and on the other hand, it will not only fill the meshing position, but also be brought to the side wall of the worm gear cavity, the side wall of the worm cavity and other positions that do not require meshing, increasing the weight and rotation resistance of the worm, and reducing the operating efficiency of the mechanism. In order to ensure the response speed of the clutch actuator and complete the shifting function in time, it is necessary to design an assembly system that can accurately apply glue to control the grease near the meshing position. Summary of the invention

[0005] The present invention aims to provide a clutch actuator assembly system, which can not only accurately apply glue, but also meet the long-term demand of the mechanism for grease.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a clutch actuator assembly system and process, including an assembly system, the assembly system includes a grease coating mechanism, a grease coating tool and a weighing mechanism, the grease coating tool includes a first front shell tool, the first front shell tool is used to fix the front shell so that the front shell is tilted, the grease coating mechanism is used to grease the connecting arc edge of the front shell, and the weighing mechanism is used to measure the total weight of the clutch actuator after assembly.

[0007] The beneficial effects of this program are:

[0008] 1. If the grease is dripped directly onto the worm, it is usually necessary to apply an excessive amount of grease to ensure long-term lubrication. However, the grease is easy to fall into the worm cavity under the action of gravity, which reduces the lubrication efficiency and is not conducive to cost control. In this solution, the grease application position is set at the edge of the connecting arc surface. Compared with adhering to the screw, the grease is more likely to adhere to the flat horizontal arc surface edge after dripping, thereby accommodating more grease. Then, when installing the fan-shaped worm gear, the excess grease is pressed under the fan-shaped turbine for storage. Therefore, it can not only apply the glue accurately, but also meet the long-term demand of the mechanism for grease.

[0009] 2. When applying grease, if the housing is placed horizontally, the connecting arc surface and the horizontal plane are perpendicular. After the grease drips, it is difficult to adhere to the edge of the connecting arc surface and can only fall directly on the worm;

[0010] Therefore, in this solution, the housing is tilted by the first housing tooling, so that the connecting arc surface is also tilted to a certain extent, so that the grease can fall on the connecting arc surface and is not easy to fall off, that is, the grease is applied around the connecting arc surface in a circle, rather than directly applying the grease on the worm;

[0011] Then remove the housing and place it horizontally. Then put the fan-shaped worm wheel into the worm wheel cavity to mesh with the worm. At the same time, scrape the grease on the edge of the connecting arc surface downward into the meshing position of the worm wheel and worm and the worm wheel cavity. Since the connecting arc surface is no longer inclined at this time, excess grease will not be transferred into the worm cavity, and most of the grease is pressed into the worm wheel cavity by the lower side of the fan-shaped worm wheel.

[0012] 3. When the lubricating oil consumption at the meshing position of the worm gear decreases, the grease in the worm gear cavity will overflow to the meshing position, replenishing the grease at that position to a certain extent.

[0013] 4. In the worm gear mechanism, the worm needs to rotate 360°, while the fan-shaped worm wheel only needs to swing back and forth within a certain range. The range of activity is small, and the resistance formed by excess grease on the fan-shaped worm wheel is small. Storing excess grease between the bottom of the worm wheel cavity and the fan-shaped worm wheel can minimize the impact of grease on mechanical movement compared to storing it in the worm gear cavity.

[0014] Furthermore, the grease coating tool also includes a worm gear tool, the worm gear tool is used to fix the sector-shaped worm gear, and the grease coating mechanism is used to grease the side of the sector-shaped worm gear tooth surface close to the bottom of the worm gear cavity.

[0015] Furthermore, the assembly system also includes a platform, which includes a shell area and a grease coating area. The grease coating mechanism is arranged in the grease coating area. The platform is provided with a first track and a second track spanning the shell area and the grease coating area. A first walking mechanism is slidably provided on the first track, and a second walking mechanism is provided on the second track. A first front shell tooling and a worm gear tooling are arranged on the first walking mechanism, and a second front shell tooling is provided on the second walking mechanism. The second front shell tooling is used to fix the front shell so that the end of the worm of the front shell close to the motor faces upward.

[0016] Furthermore, the assembly system also includes a pad selection device, which includes a guide sleeve, a support part, a first probe and a measuring device. The support part is provided on the lower side of the guide sleeve, and the lower surface of the support part is a plane. The lower surface of the support part is used to support the upper surface of the front shell. The first probe is vertically slidably arranged in the guide sleeve, and the lower surface of the first probe is used to support the upper surface of the part in the shell. The measuring device is used to measure the height difference between the upper surface of the guide sleeve of the front shell and the upper surface of the first probe. A threaded hole is vertically provided in the middle of the upper surface of the first probe, and an anti-detachment bolt is threadedly connected in the threaded hole, and the upper end of the anti-detachment bolt protrudes relative to the upper surface of the first probe.

[0017] Furthermore, it also includes an airtight detection system, which includes a linear pressing unit, the linear pressing unit includes an auxiliary pressing assembly and a linear pressing assembly, the linear pressing assembly includes a track, a sliding support, a short-range pressing arm and a horizontal driving member, the sliding support is slidably arranged on the track, the horizontal driving member is used to drive the sliding support to slide on the track, the sliding support is provided with a short-range vertical driving member, the upper end of the output shaft of the short-range vertical driving member is connected to the end of the short-range pressing arm, and the other end of the pressing part is used to block the hole on the upper side of the shell;

[0018] The auxiliary pressing assembly is installed on one side of the track. The auxiliary pressing assembly includes an auxiliary driving member and an auxiliary pressing arm. The upper end of the output shaft of the auxiliary driving member is connected to the end of the auxiliary pressing arm. The output shaft of the auxiliary driving member is used to drive the auxiliary pressing arm to lift and rotate. The other end of the auxiliary pressing arm is used to press the short-range pressing arm.

[0019] The present invention is also intended to provide a clutch actuator assembly process that can accurately apply glue and meet the long-term demand of the mechanism for grease.

[0020] To achieve the above object, the present invention adopts the following technical solution: a clutch actuator assembly process, comprising the following steps:

[0021] Step 1: Grease the inside of the front shell: place the front shell on the first front shell fixture at an angle, and use a grease coating mechanism to grease the edge of the connected arc surface of the front shell. The grease coating mechanism applies grease to the same amount of grease per time.

[0022] Step 2: Place the fan-shaped worm wheel connected with the transmission shaft key on the worm wheel fixture, and apply grease to one side of the fan-shaped worm wheel tooth surface by the grease-applying mechanism, so that the greased side of the fan-shaped worm wheel is close to the bottom of the worm wheel cavity, and push the fan-shaped worm wheel into the worm wheel cavity along the connecting arc surface. The fan-shaped worm wheel scrapes the grease on the edge of the connecting arc surface onto the worm and meshes with the worm;

[0023] Step 3: Use a weighing device to weigh the front shell to check whether the weight is equal to the designed weight.

[0024] Furthermore, in step three, before weighing, the bearing sleeve is mounted on the transmission shaft, the lower surface of the support part of the gasket device is supported on the upper surface of the front shell, the lower surface of the first probe is supported on the upper surface of the part in the shell, and the height difference between the guide sleeve and the first probe is measured, and the gasket thickness is selected according to the measured height difference. The gasket is installed on the bearing sleeve, and the rear shell and the front shell are assembled to form a shell, and the gasket and the rear shell are fit together.

[0025] Furthermore, in step three, when measuring the height difference between the guide sleeve and the first probe, the staff member picks up the guide sleeve with one hand and uses the upper index finger to hook the anti-drop bolt, so that the first probe has a tendency to tilt, and the first probe and the inner side of the guide sleeve are pressed tightly; after placing the support part below the guide sleeve on the front shell, the staff member releases the first probe with his fingers, so that the first probe falls and contacts the upper surface of the part inside the shell.

[0026] Furthermore, step 4 is also included:

[0027] 4.1 In the initial state, the auxiliary driving member drives the auxiliary pressing arm to rotate to the side away from the track, and the horizontal driving member drives the sliding support to move toward the side of the track away from the placement area of ​​the shell;

[0028] 4.2 Place the shell in the designated placement area, the horizontal drive member drives the sliding support to move toward the track close to one end of the shell, the short-range vertical drive member drives the short-range pressing arm to move downward, and the end of the short-range pressing arm blocks the hole on the shell;

[0029] 4.3 The auxiliary driving member drives the auxiliary pressing arm to rotate and descend, and the end of the auxiliary pressing arm presses on the short-stroke pressing arm, and the auxiliary short-stroke pressing arm applies a downward force to the hole.

[0030] This solution also has the following effects:

[0031] 1. The grease application position of the sector worm gear is on the side of the tooth surface close to the bottom of the worm gear cavity, that is, the lower side of the tooth surface of the sector worm gear. The grease on the lower side is hung on the upper side of the tooth surface by utilizing the friction between the sector worm gear and the edge of the connecting arc surface when installing the sector worm gear, so that the grease evenly covers the tooth surface. If the grease on the tooth surface is evenly applied in advance, the grease on the lower side of the tooth surface will be scraped away during installation, resulting in insufficient grease on the lower side of the tooth surface.

[0032] 2. The greasing speed of the greasing mechanism is usually fixed. In this scheme, the total weight of the greasing is fixed. That is, by measuring the total weight after greasing and installing the fan-shaped worm gear, it can be determined whether the greasing speed is too fast or too slow, so as to adjust the greasing speed in time to maximize the greasing efficiency.

[0033] 3. Place the housing on the first or second travel mechanism in the workpiece area, and then move the first or second travel mechanism to the grease application area for grease application. Grease application and placement of tooling are divided into different areas to avoid mutual interference. The second housing tooling is used to fix the housing, and the housing is greased at the end close to the motor through the grease application mechanism.

[0034] 4. When using the pad selection equipment, support the lower surface of the support part on the upper surface of the front shell, and transfer the height of the upper surface of the front shell to the support part and the guide sleeve; support the lower surface of the first probe on the upper surface of the part inside the shell, and transfer the height of the upper surface of the part inside the shell to the first probe; then measure the height difference between the guide sleeve and the first probe to reflect the height difference between the upper surface of the front shell and the upper surface of the part inside the shell; compared with directly measuring the height difference between the upper surface of the front shell and the upper surface of the part inside the shell, the guide sleeve and the first probe in this solution are slidably matched and the distance is short, which is convenient for measurement, and thus it is convenient to measure the height difference between the upper surface of the front shell and the upper surface of the part inside the shell. When the front shell is placed horizontally, the upper surface of the front shell is used as a reference surface with high precision. Therefore, supporting the lower surface of the support part on the upper surface of the front shell can ensure that the lower surface of the support part is also horizontal, thereby ensuring that the guide cylinder is vertically arranged, and further ensuring that the first probe can smoothly fall on the upper surface of the parts in the shell under the action of gravity. If the fan-shaped worm gear is not firmly installed at this time, the pressure of the gravity of the first probe on the fan-shaped worm gear can press the fan-shaped worm gear into the correct position, thereby ensuring that the position of the fan-shaped turbine is consistent with the position after the installation of the gasket and the rear shell.

[0035] 5. In order to facilitate regular inspection of the accuracy of the first probe, it is necessary to take it down for inspection frequently. Therefore, no limit device is set between the guide sleeve and the first probe, and the first probe can slide out of the guide sleeve; in actual use, in order to facilitate one-handed picking up and prevent the first probe from slipping out of the guide sleeve, this scheme provides an anti-slip bolt on the upper surface of the first probe. When the staff picks up the guide sleeve with one hand, they only need to use the upper index finger to hook the anti-slip bolt to make the first probe tend to tilt, so that the first probe and the inner side of the guide sleeve are pressed tightly, thereby preventing the first probe from slipping out of the guide sleeve; after placing the support part below the guide sleeve on the front shell, the finger can release the first probe, so that the first probe falls and contacts the upper surface of the parts in the shell, so as to measure the height difference.

[0036] Compared with setting the anti-drop bolt, if the limiting structure is directly set on the first probe or the guide sleeve to prevent the first probe from sliding out of the guide sleeve, the first probe will constantly collide with the limiting structure during continuous use, and the sliding between the first side head and the guide sleeve will no longer be vertical and smooth, thereby affecting the accuracy of the measurement result. The anti-drop bolt moves up and down relative to the upper surface of the first probe by rotating, so as to adapt to the height difference between different front shells and parts inside the shell, thereby increasing the scope of application.

[0037] 6. When using the airtight detection system, the length of the short-stroke pressing arm is adjusted according to the position from the hole on the upper surface of the workpiece to the edge. However, when the short-stroke pressing arm is relatively long, the vertical force applied by the short-stroke vertical driving member cannot be completely transmitted to the free end of the short-stroke pressing arm, and part of the vertical force is offset by the deformation of the short-stroke pressing arm itself; therefore, the main function of the short-stroke vertical driving member is to make the free end of the short-stroke pressing arm close to the hole on the upper surface of the workpiece; and the vertical force is mainly provided by the auxiliary driving member.

[0038] 7. Since the function of the auxiliary driving component is to press the short-range pressing arm, the length of the auxiliary pressing arm does not need to be too long. During installation, the distance between the auxiliary driving component and the track can be shortened as much as possible, so that the cantilever length of the short-range pressing arm is smaller and the structural deformation is smaller. In addition, the auxiliary driving component can effectively transmit the vertical force to the short-range pressing arm, so that the blocked hole is tight. BRIEF DESCRIPTION OF THE DRAWINGS

[0073] Step 2: Place the fan-shaped worm wheel 12 keyed to the transmission shaft 19 on the worm wheel fixture 43, and the grease coating mechanism 6 greases one side of the tooth surface of the fan-shaped worm wheel 12, so that the greased side of the fan-shaped worm wheel is close to the bottom of the worm wheel cavity 14, and push the fan-shaped worm wheel 12 into the worm wheel cavity 14 along the connecting arc surface. The fan-shaped worm wheel scrapes the grease on the edge of the connecting arc surface onto the worm and meshes with the worm, and rotates the worm so that the grease at the meshing position of the worm and the fan-shaped worm wheel is scraped onto the entire circumference of the worm;

[0074] The third step is to fit the bearing sleeve 18 onto the transmission shaft 19, support the lower surface of the support portion 72 of the gasket device on the upper surface of the front shell 11, support the lower surface of the first probe 73 on the upper surface of the parts in the shell, measure the height difference between the guide sleeve 71 and the first probe 73, select the gasket thickness according to the measured height difference, install the gasket on the bearing sleeve 18, and assemble the rear shell and the front shell 11 to form a shell, and fit the gasket and the rear shell; when measuring the height difference between the guide sleeve 71 and the first probe 73, the staff picks up the guide sleeve 71 with one hand, and uses the upper index finger to hook the anti-drop bolt 74, so that the first probe 73 tends to tilt, and the first probe 73 and the inner side of the guide sleeve 71 are pressed tightly; after placing the support portion 72 below the guide sleeve 71 on the front shell 11, release the first probe 73 with your fingers, so that the first probe 73 falls and contacts the upper surface of the parts in the shell;

[0075] Use a weighing device to weigh the front shell 11 to check whether the weight is equal to the designed weight. If not, it means that the output dosage of the grease coating mechanism 6 is inaccurate and needs to be adjusted in time.

[0076] Step 4: Airtightness test:

[0077] 4.1 In the initial state, the auxiliary driving member a61 drives the auxiliary pressing arm a62 to rotate to the side away from the track a41, and the horizontal driving member a42 drives the sliding support to move toward the side of the track a41 away from the placement area of ​​the shell;

[0078] 4.2 Place the shell in the designated placement area, the horizontal driving member a42 drives the sliding support to move toward the track a41 close to one end of the shell, the short-range vertical driving member a51 drives the short-range pressing arm a52 to move downward, and the end of the short-range pressing arm a52 blocks the hole on the shell;

[0079] 4.3 The auxiliary driving member a61 drives the auxiliary pressing arm a62 to rotate and descend, and the end of the auxiliary pressing arm a62 presses on the short-stroke pressing arm a52, and the auxiliary short-stroke pressing arm a52 applies a downward force to the hole.
