Description
Technical fields:
[0001] This invention belongs to the technical field of tire assembly equipment, specifically referring to an automatic disc brake disc locking device. Background technology:
[0002] Currently, in the wheel manufacturing process, disc brake discs need to be installed on the wheel hub so that they can cooperate with the braking components to brake the wheel. The existing installation structure between the disc brake disc and the wheel hub consists of several mounting screw holes on both the disc brake disc and the wheel hub. Screws are passed through two corresponding mounting screw holes to connect the disc brake disc and the wheel hub. However, the current method involves manually screwing the disc brake disc and the wheel hub one by one, which is not only time-consuming and labor-intensive, but also prone to inconsistent torque during manual tightening, leading to unstable connections between the disc brake disc and the wheel hub. Summary of the Invention:
[0003] The purpose of this invention is to provide an automatic disc brake disc mounting device with a high degree of automation and high assembly efficiency. Simply place the wheel hub and disc brake disc at the loading station, and the loading component will transport them to the assembly station. Multiple screw tightening devices will then tighten the screws to the corresponding mounting screw holes with a rated torque.
[0004] This invention is implemented as follows:
[0005] An automatic disc brake disc locking device includes a frame, a locking column and an assembly station located in front of the locking column, a feeding station and a feeding assembly that can transport wheel hubs with disc brake discs mounted on the feeding station to the assembly station, a locking movable seat that is slidably connected vertically to the locking column, the locking movable seat being driven to move up and down by a lifting and adjusting cylinder fixed on the locking column, and a plurality of screw locking devices on the locking movable seat, the locking ends of which correspond one-to-one with the assembly screw holes of the disc brake disc at the assembly station.
[0006] In the aforementioned automatic disc brake disc locking device, the feeding assembly includes an annular conveyor track mounted on a frame. Several assembly movable seats are slidably connected to the annular conveyor track in a clockwise or counterclockwise direction. The assembly movable seats have assembly slots for placing wheel hubs. The assembly station and the feeding station are two positions on the annular conveyor track, respectively.
[0007] In the aforementioned automatic disc brake mounting device, the feeding assembly includes a linear conveying track mounted on a frame, an assembly moving seat slidably connected to the linear conveying track, and an assembly slot for placing the wheel hub on the assembly moving seat. The assembly station and the feeding station are two end positions on the linear conveying track, respectively.
[0008] In the aforementioned automatic disc brake disc locking device, a repositioning bracket is provided on the frame located on the conveying path between the loading station and the assembly station. A repositioning seat is lifted and connected to the repositioning bracket, and a positioning pin is provided at the bottom of the repositioning seat, penetrating one of the assembly screw holes on the disc brake disc.
[0009] In the aforementioned automatic disc brake disc locking device, the screw locking device includes an upper lifting support that is vertically slidably connected to the locking moving base, and a lower lifting support located below the lower lifting support. The upper lifting support is equipped with several locking servo motors, and the lower lifting support is equipped with a wire feeding chuck corresponding to each locking servo motor. The wire feeding chuck has a wire feeding cavity with a lower port corresponding to the assembly screw hole of the disc brake disc at the assembly station. The output end of the locking servo motor is connected to a pneumatic screwdriver shaft that rotates and lifts on the lower lifting support via a universal joint. The bottom end of the pneumatic screwdriver shaft is located inside the upper end of the wire feeding cavity, and a bypass wire feeding port is provided on one side of the wire feeding cavity. The bypass wire feeding port is connected to the discharge end of the wire feeding assembly via a negative pressure pipe. A wire clamping assembly that can restrict the screw from falling is provided at the lower port of the wire feeding cavity. The screw is separated from the wire clamping assembly by the downward movement of the pneumatic screwdriver shaft.
[0010] In the aforementioned automatic disc brake mounting device, an upper actuator is provided directly below the upper lifting support, an upper actuator cylinder is fixed on the upper actuator, and the upper actuator moves up and down synchronously with the upper lifting support through the telescopic end of the upper actuator cylinder. The mounting servo motor is fixed on the upper actuator. A lower actuator is provided directly below the lower lifting support, a lower actuator cylinder is fixed on the lower actuator, and the lower actuator moves up and down synchronously with the lower lifting support through the telescopic end of the lower actuator cylinder. The wire feeding chuck is provided on the lower actuator.
[0011] In the aforementioned automatic disc brake mounting device, the lower actuator has radially spaced slots corresponding to the wire feed chucks. A variable diameter turntable is horizontally rotatably connected to the lower actuator. The variable diameter turntable has arc-shaped adjustment holes corresponding to the wire feed chucks. The wire feed chucks are slidably connected to the corresponding radial slots and arc-shaped adjustment holes through bushings. The inner hole of the bushing allows the corresponding air screwdriver shaft to pass through into the wire feed cavity. The rotation of the variable diameter turntable drives the bushing and the wire feed chucks to move radially along the radial slots.
[0012] In the aforementioned automatic disc brake disc locking device, the wire clamping assembly includes wire clamping claws that are arranged opposite each other and hinged in the middle to the wire supply chuck. A compression spring is provided between the upper end of each wire clamping claw and the wire supply chuck. A clamping ring is formed between the lower ends of the two wire clamping claws for clamping the screw head end, and the inner ring wall of the clamping ring is a conical structure with a larger upper part and a smaller lower part.
[0013] In the aforementioned automatic disc brake mounting device, the wire feeding assembly includes a feeding container corresponding to the wire feeding chucks and mounted on a frame, and a vibrating conveyor motor. The vibrating end of the vibrating conveyor motor has a vibrating conveyor rail arranged longitudinally. The feeding end of the vibrating conveyor rail extends into the feeding container. A sorting cylinder and a sorting slide plate are arranged laterally on the frame at the discharge end of the vibrating conveyor rail. The side wall of the sorting slide plate near the vibrating conveyor rail has a section that communicates with the feeding end of the vibrating conveyor rail and allows the screws to freely descend. The feed gap is located below the negative pressure pipe. The top surface of the sorting slide plate is longitudinally connected to the limiting slide plate. The limiting slide plate has a U-shaped notch on its side wall near the vibrating conveyor rail that can be supported directly below the screw head. The limiting slide plate is slidably engaged with the strip-shaped oblique hole on the frame through a pin. When the sorting cylinder extends outward, the limiting slide plate slides near the vibrating conveyor rail and supports the screw at the feed gap. When the sorting cylinder extends inward, the limiting slide plate slides away from the vibrating conveyor rail and separates from the screw at the feed gap.
[0014] In the aforementioned automatic disc brake mounting device, an inclined slide rail is provided in the feeding container located at the feeding end of the vibrating conveyor slide rail. The inclined slide rail is driven by a lifting cylinder fixed on the frame to move vertically up and down. When the inclined slide rail moves upward to its extreme value, the lower end of the inclined slide rail is connected to the feeding end of the vibrating conveyor slide rail. A scraper is provided on the feeding container. The lower edge of the scraper has a discharge notch for the feeding end of the vibrating conveyor slide rail to pass through. The discharge cylinder fixed on the frame drives the scraper to move back and forth along the feeding end of the vibrating conveyor slide rail.
[0015] The outstanding advantages of this invention compared to the prior art are:
[0016] This invention features a high degree of automation and high assembly efficiency. Simply place the wheel hub and disc brake disc at the loading station, and the loading component will transport them to the assembly station.

[0027] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —9:
[0028] Example 1:
[0029] An automatic disc brake disc locking device includes a frame 1, on which a locking column 2 and an assembly station located in front of the locking column 2 are provided. The frame 1 is provided with a feeding station and a feeding component that can transport the wheel hub 4 with the disc brake disc 3 mounted on the feeding station to the assembly station. A locking moving seat 5 is slidably connected vertically to the locking column 2. The locking moving seat 5 is driven to move up and down by a lifting and adjusting cylinder 6 fixed on the locking column 2. The locking moving seat 5 is provided with a plurality of screw locking devices 7, the locking ends of which correspond one-to-one with the assembly screw holes of the disc brake disc 3 at the assembly station.
[0030] This invention features a high degree of automation and high assembly efficiency. Simply place the wheel hub 4 and disc brake disc 3 at the loading station, and the loading component will transport them to the assembly station. Multiple screw tightening devices 7 will then tighten the screws to the corresponding assembly screw holes with the rated torque, ensuring that the disc brake disc 3 can be stably, firmly, and reliably connected to the wheel hub 4.
[0031] To ensure the continuous and uninterrupted transport of the wheel hub 4 and disc brake disc 3 to the assembly station by the loading assembly, in this embodiment, the loading assembly includes an annular conveyor track 8 mounted on the frame 1. Several assembly moving seats 9 are slidably connected to the annular conveyor track 8 in a clockwise or counterclockwise direction. Each assembly moving seat 9 has an assembly slot for placing the wheel hub 4. The assembly station and the loading station are two locations on the annular conveyor track 8, respectively. Furthermore, a material return station is provided on the conveying path between the assembly station and the loading station to transfer the wheel hub 4 to the next station. An annular conveyor chain is installed within the annular conveyor track 8, which drives each assembly moving seat 9 to move together.
[0032] Since the wheel hub 4 is placed manually at the loading station and then the disc brake disc 3 is placed on the wheel hub 4, a repositioning bracket 11 is installed on the frame 1 along the conveying path between the loading station and the assembly station to ensure that the disc brake disc 3 is circumferentially positioned on the wheel hub 4. A repositioning seat 12 is connected to the repositioning bracket 11, and a positioning pin 13 is provided at the bottom of the repositioning seat 12, penetrating one of the mounting screw holes on the disc brake disc 3. That is, after the assembly moving seat 9 is conveyed and moved to directly below the repositioning seat 12, the repositioning cylinder 43 fixed on the repositioning bracket 11 drives the repositioning seat 12 and the positioning pin 13 to descend together, so that the positioning pin 13 can be inserted into the mounting screw holes on the disc brake disc 3 and the wheel hub 4, thereby achieving the positional positioning between the disc brake disc 3 and the wheel hub 4.
[0033] Furthermore, in order to effectively screw the screws into the mounting screw holes of the disc brake disc 3 and the wheel hub 4, the screw locking device 7 has the following specific structure: The screw locking device 7 includes an upper lifting support 14 that is vertically slidably connected to the locking moving base 5, and a lower lifting support 15 located below the lower lifting support 15. The upper lifting support 14 is provided with a plurality of locking servo motors 16, and the lower lifting support 15 is provided with wire feeding chucks 17 that correspond one-to-one with the locking servo motors 16. The wire feeding chucks 17 have a lower port and an assembly station inside. The screw feed cavity corresponding to the mounting screw hole of the disc brake disc 3 is connected to the output end of the locking servo motor 16 via a universal joint 18. The air screw shaft 19 rotates and is engaged with the lower lifting support 15. The bottom end of the air screw shaft 19 is located in the upper end of the screw feed cavity. A bypass screw feed port is provided on one side of the screw feed cavity. The bypass screw feed port is connected to the discharge end of the screw feed assembly 20 via a negative pressure pipe. A screw clamping assembly is provided at the lower port of the screw feed cavity to limit the screw from falling. The screw is separated from the screw clamping assembly by the downward movement of the air screw shaft 19.
[0034] The locking moving seat 5, driven by the lifting adjustment cylinder 6, adjusts its height according to the actual size of the wheel hub 4 being assembled. The upper lifting support 14 and the lower lifting support 15 are driven independently by corresponding servo motors via screws and nuts. During actual operation, the upper lifting support 14 and the lower lifting support 15 descend together to a designated height, aligning the lower port of the wire feeding cavity with its corresponding mounting screw hole. Subsequently, the upper lifting support 14 moves downward relative to the lower lifting support 15, allowing the air screwdriver shaft 19 to push the screw downward to separate from the wire clamping assembly. The locking servo motor 16 drives the air screwdriver shaft 19 to rotate, enabling the screw to be screwed into the mounting screw hole of the disc brake 3 and the wheel hub 4. Simultaneously, the wire feeding assembly 20 uses a negative pressure pipe to feed screws one by one into the lower port of the wire feeding cavity, where they are clamped by the wire clamping assembly.
[0035] Furthermore, since the upper lifting support 14 and the lower lifting support 15 bear a large load, it is cumbersome and inefficient to drive the upper lifting support 14 or the lower lifting support 15 to move up and down for screw tightening operations using a servo motor. Moreover, it cannot effectively coordinate with the tightening drive of the locking servo motor 16. Therefore, in this embodiment, an upper actuator 21 is provided directly below the upper lifting support 14. An upper actuator cylinder 22 is fixed on the upper actuator 21, and the upper actuator 21 is connected to the upper lifting support 14 via the telescopic end of the upper actuator cylinder 22. The support 14 moves up and down synchronously. The locking servo motor 16 is fixed on the upper actuator 21. The lower actuator 23 is located directly below the lower lifting support 15. The lower actuator 23 is fixed with a lower actuator cylinder 24. The lower actuator 23 moves up and down synchronously with the lower lifting support 15 through the telescopic end of the lower actuator cylinder 24. The wire feeding chuck 17 is located on the lower actuator 23. The upper actuator cylinder 22 and the lower actuator cylinder 24 cooperate with the locking servo motor 16 to rotate, so as to effectively ensure the screw is tightened and fixed.
[0036] Furthermore, considering that the radial positions of the mounting screw holes are different for hubs of different sizes 4, the lower actuator 23 is provided with radial strip holes 25 corresponding to the wire feed chucks 17. A variable diameter turntable 26 is horizontally rotatably connected to the lower actuator 23. The variable diameter turntable 26 is provided with arc-shaped adjustment holes 27 corresponding to the wire feed chucks 17. The wire feed chucks 17 are slidably connected to the corresponding radial strip holes 25 and arc-shaped adjustment holes 27 through bushings 28. The inner hole of the bushing 28 allows the corresponding air screwdriver shaft 19 to pass through into the wire feed cavity. The rotation of the variable diameter turntable 26 drives the bushing 28 and the wire feed chucks 17 to move radially along the radial strip holes 25.
[0037] Meanwhile, the wire clamping assembly is directly an elastic baffle. In this embodiment, the specific structure adopted by the wire clamping assembly is as follows: the wire clamping assembly includes wire clamping claws 29 that are arranged opposite to each other and hinged in the middle to the wire feeding chuck 17. A compression spring 30 is provided between the upper end of each of the two wire clamping claws 29 and the wire feeding chuck 17. A clamping ring for clamping the screw head is formed between the lower ends of the two wire clamping claws 29, and the inner ring wall of the clamping ring is a conical structure with a larger upper part and a smaller lower part.
[0038] The wire feeding assembly 20 can be a common vibrating conveyor device. In this embodiment, the specific structure of the wire feeding assembly 20 is as follows: The wire feeding assembly 20 includes a feeding container 31 corresponding to the wire feeding chuck 17 and mounted on the frame 1, and a vibrating conveyor motor 32. The vibrating end of the vibrating conveyor motor 32 is provided with a vibrating conveyor slide rail 33 along the longitudinal direction. The feeding end of the vibrating conveyor slide rail 33 extends into the feeding container 31. A sorting cylinder 34 and a sorting slide plate 35 are provided on the frame 1 at the discharge end of the vibrating conveyor track along the transverse direction. The sorting slide plate 35 has a side wall near the vibrating conveyor slide rail 33 that can interact with the vibrating conveyor track. The feed end of the channel is connected to a feed notch that allows the screw to fall freely. The corresponding end of the negative pressure pipe is located directly below the feed notch. The top surface of the sorting slide plate 35 is longitudinally slidably connected to a limiting slide plate 36. The limiting slide plate 36 has a U-shaped notch 37 on its side wall near the vibrating conveyor rail 33 that can be supported directly below the screw head. The limiting slide plate 36 is slidably engaged with the strip-shaped oblique hole 38 on the frame 1 through a pin. When the sorting cylinder 34 extends and retracts outward, the limiting slide plate 36 slides close to the vibrating conveyor rail 33 and supports the screw at the feed notch. When the sorting cylinder 34 extends and retracts inward, the limiting slide plate 36 slides away from the vibrating conveyor rail 33 and separates from the screw at the feed notch. Under the vibration drive of the vibrating conveyor motor 32, the screws in the feed container 31 will move along the vibrating conveyor track to the feed gap of the sorting slide plate 35, and be supported by the U-shaped gap 37 of the limiting slide plate 36. The sorting cylinder 34 extends and retracts inward, so that the screws are separated from the limiting slide plate 36 and fall into the negative pressure pipe.
[0039] Furthermore, in order to ensure that the screws in the feed container 31 can effectively enter the vibrating conveyor rail 33, and to ensure that the screws entering the vibrating conveyor rail 33 are in the position of head up and tail down, an inclined rail 39 is provided in the feed container 31 located at the feed end of the vibrating conveyor rail 33. The inclined rail 39 is driven to move vertically up and down by a lifting cylinder 40 fixed on the frame 1. When the inclined rail 39 moves upward to its extreme value, the lower end of the inclined rail 39 is connected to the feed end of the vibrating conveyor rail 33. A scraper 41 is provided on the feed container 31. The lower edge of the scraper 41 has a discharge notch for the feed end of the vibrating conveyor rail 33 to pass through. The discharge cylinder 42 fixed on the frame 1 drives the scraper 41 to move back and forth along the feed end of the vibrating conveyor rail 33.
[0040] Example 2:
[0041] This embodiment is basically the same in structure as the first embodiment described above. The main difference is that in the above-described automatic disc brake disc 3 locking device, the feeding component includes a linear conveying track 10 mounted on the frame 1. An assembly moving seat 9 is slidably connected to the linear conveying track 10. The assembly moving seat 9 has an assembly slot for placing the wheel hub 4. The assembly station and the feeding station are two end positions on the linear conveying track 10, respectively. That is, only the assembly moving seat 9 moves back and forth on the linear conveying track 10 to realize the feeding and unloading of the wheel hub 4 at the feeding station, and the tightening and locking of the wheel hub 4 and the disc brake disc 3 at the assembly station.
[0042] The above embodiments are merely one of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes made in accordance with the shape, structure and principle of the present invention should be covered within the protection scope of the present invention.
