Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing technology for automotive parts, and in particular to a flexible automated production line for automotive differential housing robots. Background Technology

[0002] The differential housing is the core transmission base of the drive axle differential assembly. It houses and positions the planetary gears, half-shaft gears, and planetary gear shafts, and is rigidly connected to the main reduction gear ring to achieve torque transmission and power distribution. The structural strength and machining accuracy of the housing directly affect the reliability of the differential. Currently, differential housings are generally made of ductile iron through integral casting or a split-type assembly structure. These technologies are mature, cost-effective, and widely used in passenger and commercial vehicles.

[0003] Automotive differential housings are mostly made of ductile iron castings. The blanks have characteristics such as flash, large dimensional deviations, and high surface roughness. After precision machining, the flange face and hole end face of the housing have strict precision requirements and the surface is extremely easy to scratch. Traditional robot gripping mechanisms generally adopt an integrated fixed gripper structure, with a simple overall structure and fixed clamping mode. This makes it impossible to meet the working conditions of rough gripping of blanks and stable gripping of precision parts at the same time, which greatly reduces the overall practicality. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides a flexible automated production line for automotive differential housing robots, aiming to solve the problems in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a main body, a replacement mechanism is installed at the upper end of the main body, and a translation mechanism is installed at the lower end of the main body; The replacement mechanism includes a claw body, a square groove on the upper surface of the claw body, a fixing bolt fixedly connected to the inner bottom of the square groove, a fixing nut threadedly connected to the upper end of the fixing bolt, a limit block slidably connected to the outer surface of the fixing bolt, a movable groove on the upper surface of the limit block, the interior of the movable groove slidably connected to the outer surface of the fixing bolt, a locking groove on the inner bottom of the square groove, a locking block slidably connected to the interior of the locking groove, and a gripper assembly installed on the surface of the claw body.

[0006] As a further description of the above technical solution: The number of claw body, square groove, fixing bolt, fixing nut, limiting block and movable groove is two, and they are mirror symmetrical along the vertical central axis of the main body.

[0007] As a further description of the above technical solution: The gripper assembly includes gripper blocks, the surface of which is fixedly connected to one end of the clamping block, and there are two gripper blocks.

[0008] As a further description of the above technical solution: A rigid clamping block is fixedly connected to the side surface of one of the gripper blocks, and a flexible clamping block is fixedly connected to the side surface of the other gripper block.

[0009] As a further description of the above technical solution: The translation mechanism includes a base, and a protective cover is fixedly connected to the inner top of the base.

[0010] As a further description of the above technical solution: A servo motor is fixedly connected to the side surface of the protective cover, and the drive end of the servo motor passes through the inside of the protective cover and extends into the inside of the protective cover.

[0011] As a further description of the above technical solution: The drive end of the servo motor is fixedly connected to an active tooth. The outer side of the active tooth passes through the interior of the base and extends to the top of the base. A rack is fixedly connected to the lower surface of the main body. The rack meshes with the active tooth. A support assembly is installed below the main body.

[0012] As a further description of the above technical solution: The support assembly includes a sliding seat, the upper surface of which is fixedly connected to the lower surface of the main body. A groove is formed on the lower surface of the sliding seat. A support block is fixedly connected to the upper surface of the base, and the upper end of the support block is slidably connected to the inside of the groove.

[0013] The present invention has the following beneficial effects: 1. In this invention, by setting a replacement mechanism, after the fixing nut releases the restriction on the limiting block, the limiting block moves backward, releasing the restriction on the clamping block. The gripper assembly can then be removed and replaced to adapt to the usage requirements under different working conditions. After the new clamping block is inserted into the slot, the limiting block is moved back to the top of the slot, and the fixing nut is tightened to restrict the clamping block. That is, the new gripper assembly is fixed. Thus, the gripper assembly that can be replaced to adapt to the rough gripping of blanks and the stable gripping of precision parts according to different working conditions can be improved, thereby improving the adaptability of the device and greatly enhancing its overall practicality.

[0014] 2. In this invention, the translation mechanism controls the start of the servo motor according to the needs of different processing positions. With the cooperation of the active gear and the rack, the main body is driven to move along the length direction of the support block, so that the processing position of the main body can be adjusted at will according to the needs. This allows the processing position of the device to be adjusted in real time, greatly expanding the effective working range of the device and facilitating the sequential connection of multiple processing areas to meet the needs of large-span production lines.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see the appendix Figure 1 - Appendix Figure 7One embodiment of the present invention includes a main body 1, a replacement mechanism 2 mounted on the upper end of the main body 1, and a translation mechanism 3 mounted on the lower end of the main body 1. The replacement mechanism 2 includes a claw body 202, a square groove 203 formed on the upper surface of the claw body 202, a fixing bolt 204 fixedly connected to the inner bottom of the square groove 203, a fixing nut 205 threadedly connected to the upper end of the fixing bolt 204, a limit block 206 slidably connected to the outer surface of the fixing bolt 204, a movable groove 207 formed on the upper surface of the limit block 206, the interior of the movable groove 207 slidably connected to the outer surface of the fixing bolt 204, and a slot 208 formed at the inner bottom of the square groove 203. The slot 208 has a sliding connection to a locking block 209. The surface of the claw body 202 is equipped with a gripper assembly 201. There are two claw bodies 202, square slots 203, fixing bolts 204, fixing nuts 205, limiting blocks 206 and movable slots 207, which are mirror-symmetrical along the vertical central axis of the main body 1. The gripper assembly 201 includes a gripper block 2011. The surface of the gripper block 2011 is fixedly connected to one end of the locking block 209. There are two gripper blocks 2011. A rigid clamping block 2012 is fixedly connected to the side surface of one gripper block 2011, and a flexible clamping block 2013 is fixedly connected to the side surface of the other gripper block 2011. Specifically, there are four slots 208 and four blocks 209, arranged in pairs, located at the bottom of the inner sides of two square slots 203, allowing the gripper block 2011 to be stably mounted on the gripper body 202. The limiting block 206 is T-shaped. The lateral position of the limiting block 206 can simultaneously restrict the two blocks 209, facilitating the fixation of the blocks 209. The vertical position of the limiting block 206 can pass through the interior of the square slot 203 and extend to the outside of the gripper body 202. The vertical position of the limiting block 206 allows it to be pulled to move after the restriction of the limiting block 206 is released, facilitating the release of the restriction on the blocks 209. The movable slot 207 can... The limiting block 206 is designed to facilitate linear movement on the fixing bolt 204. The fixing nut 205 can apply downward pressure to the limiting block 206, thereby fixing the limiting block 206. This allows for the restriction and fixation of the clamping block 209 after its installation. The two gripper blocks 2011 can be fitted with a rigid clamping block 2012 and a flexible clamping block 2013, respectively. The flexible clamping block 2013 is a non-metallic buffer pad. When the rigid clamping block 2012 is installed on the surface of the two gripper blocks 2011, it can coarsely grip the blank. When the flexible clamping block 2013 is installed on the surface of the gripper blocks 2011, it can stably grip the precision part, meeting the clamping requirements of different working conditions.

[0019] Please see the appendix Figure 1 -Appendix Figure 7The translation mechanism 3 includes a base 302, a protective cover 303 is fixedly connected to the inner top of the base 302, a servo motor 304 is fixedly connected to the side surface of the protective cover 303, the transmission end of the servo motor 304 passes through the interior of the protective cover 303 and extends into the interior of the protective cover 303, an active tooth 305 is fixedly connected to the transmission end of the servo motor 304, the outer side of the active tooth 305 passes through the interior of the base 302 and extends to the top of the base 302, a rack 306 is fixedly connected to the lower surface of the main body 1, the rack 306 meshes with the active tooth 305, a support assembly 301 is installed below the main body 1, the support assembly 301 includes a sliding seat 3011, the upper surface of the sliding seat 3011 is fixedly connected to the lower surface of the main body 1, a groove 3012 is opened on the lower surface of the sliding seat 3011, a support block 3013 is fixedly connected to the upper surface of the base 302, and the upper end of the support block 3013 is slidably connected to the interior of the groove 3012; Specifically, there are two support components 301, which are mirror-symmetrical along the vertical central axis of the base 302, so that the base 302 can provide stable support for the main body 1 and enable the main body 1 to move smoothly in a straight line. By starting the servo motor 304, the rotation of the active gear 305 can be controlled, so that the rack 306 moves in a straight line, which can drive the main body 1 to move in a straight line, thereby changing the processing range of the main body 1 and meeting the needs of large-span production lines.

[0020] Working principle: When in use, according to the processing range requirements of the main body 1, the servo motor 304 is started, which makes the active gear 305 rotate, and the rack 306 that meshes with it moves linearly, thereby controlling the main body 1 to move linearly under the support of the support block 3013, so that the main body 1 moves to the predetermined processing position. When the gripper assembly 201 needs to be replaced, rotate the fixing nut 205 to release the pressure on the limiting block 206, then pull the limiting block 206 to move it and release the restriction on the locking block 209. The locking block 209 can then be moved upwards and removed, thereby removing the rigid clamping block 2012 and the gripper block 2011. Then, install the new gripper block 2011 with the flexible clamping block 2013 installed. Align the locking block 209 with the slot 208 and insert it. Then, push the limiting block 206 toward the locking block 209 and turn the fixing nut 205 to apply downward pressure to the limiting block 206, pressing the limiting block 206 down and fixing it. This completes the switching between the rigid clamping block 2012 and the flexible clamping block 2013, meeting the clamping requirements of different working conditions.
