Description

Technical Field

[0001] This utility model relates to the field of caster bracket assembly technology, specifically a caster bracket positioning device. Background Technology

[0002] Caster brackets are devices used to support and secure casters, typically installed on equipment or furniture that needs to be moved. Taking a swivel caster bracket structure as an example, it mainly includes a support plate, a turntable, and a mounting frame. The turntable is mounted on the lower end face of the support plate via bearings, allowing the caster to rotate freely. The mounting frame is fixed to the lower end face of the turntable and is used to mount the wheel. Riveting and assembling caster brackets is a core process in caster production. Mechanical force deforms the rivets (or riveted parts), achieving a permanent connection between components such as the support plate, turntable, and mounting frame. The quality of this assembly directly determines the caster's load-bearing capacity, rotational flexibility, and service life. The essence of caster bracket riveting is utilizing the plastic deformation of metal (rivets / riveting areas), using pressure or impact to cause morphological changes such as "upsetting" and "flanging" in the riveted parts. This creates a "mechanical locking structure" at the junction of the bracket and mating components (such as roller shafts and bearing sleeves), thus replacing welding and bolt connections to achieve permanent fixation without threads or welds.

[0003] During the riveting process, the support plate, turntable, mounting frame and rivets need to be assembled and positioned. Then, the assembled components are moved to the stamping area by the feeding turntable of the riveting machine for stamping. During the rotation and conveying process of the feeding turntable, the components need to be positioned to avoid deviation.

[0004] To address the aforementioned problems, we propose a caster bracket positioning device. Utility Model Content

The support plate has screw holes on all four sides of its inner side. A positioning assembly includes a mounting base plate with a support column at its upper center. The support column has a positioning hole at its top center and four sets of positioning rods around its perimeter. A clamping assembly is located on both sides of the positioning assembly and includes two sets of clamping pressure plates located on the upper sides of both ends of the support column. These clamping pressure plates are used to press and clamp the support plate at both ends.

[0007] Preferably, the bottom of the clamping plate is provided with an electric push rod, which is fixedly installed on both sides of the upper end of the mounting base plate. The electric push rod is used to drive the clamping plate to move up and down.

[0009] Preferably, the diameter of the positioning hole matches the diameter of the rivet, and the bottom of the rivet is inserted into the positioning hole during installation.

[0010] Preferably, the four sets of positioning rods surround the periphery of the support column and are respectively inserted into the screw holes around the support plate.

[0011] Preferably, mounting holes are provided on all four sides of the inner side of the mounting base plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The positioning device proposed in this utility model can position and clamp the caster frame assembly during use.

[0015] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example: Refer to Figure 1 - Figure 3As shown, a caster bracket positioning device of this embodiment includes a caster bracket assembly, which includes a mounting frame 1, a rotating turntable 2, a support plate 3, and rivets 4. The support plate 3 has screw holes 31 on all four sides of its inner side. During installation, the rivets 4 need to be passed through the center holes of the mounting frame 1, the rotating turntable 2, and the support plate 3 in sequence. Then, the rivets 4 are stamped and embossed by a riveting machine to form a riveting structure, so that the mounting frame 1, the rotating turntable 2, and the support plate 3 are combined into a whole.

[0016] The positioning component includes a mounting base plate 5, a support column 7 is provided at the upper center of the mounting base plate 5, a positioning hole 8 is provided at the top center of the support column 7, and four sets of positioning rods 10 are provided around the support column 7; the clamping component is located on both sides of the positioning component, and the clamping component includes two sets of clamping pressure plates 12, which are located on the upper sides of both ends of the support column 7, and are used to press and clamp the support plate 3 at both ends.

[0017] Four sets of positioning rods 10 surround the support column 7 and are respectively inserted into the screw holes 31 around the support plate 3 to limit and fix the support plate 3. Then, the clamping pressure plates 12 on both sides press and fix the two ends of the support plate 3, so that the combination of mounting bracket 1, rotating turntable 2, support plate 3 and rivet 4 is firmly pressed on the top of the support column 7, avoiding loosening and displacement during the feeding process.

[0018] An electric push rod 11 is provided at the bottom of the clamping pressure plate 12. The electric push rod 11 is fixedly installed on both sides of the upper end of the mounting base plate 5. The electric push rod 11 is used to drive the clamping pressure plate 12 to move up and down. When it rises, it is convenient for the staff to install each component. When it falls, it can press and clamp the two ends of the support plate 3 to enhance the stability of the assembly.

[0019] In some examples, a support seat 9 is provided at the bottom of the support column 7. The support seat 9 is fixedly installed at the upper middle part of the mounting base plate 5. The provision of the support seat 9 enhances the rigidity of the support column 7, thereby increasing the pressure that the support column 7 can withstand and enhancing the stability during the stamping process.

[0020] In some examples, the diameter of the locating hole 8 matches the diameter of the rivet 4, and the bottom of the rivet 4 is inserted into the locating hole 8 during installation.

[0021] In some examples, mounting holes 6 are provided around the inner perimeter of the mounting base plate 5. Fixing bolts are installed in the mounting holes 6 to fix the entire positioning device on the feeding turntable of the riveting machine for use.

[0022] The working principle of this utility model is as follows: When in use, the mounting base plate 5 must first be fixedly installed on the feeding turntable of the riveting machine. When the caster frame assembly needs to be riveted and assembled, the operator first needs to insert the bottom of the rivet 4 into the positioning hole 8 at the top of the support column 7, and then put on the mounting bracket 1, the rotating turntable 2 and the support plate 3, so that the rivet 4 passes through the center hole of the mounting bracket 1, the rotating turntable 2 and the support plate 3. When installing the support plate 3, it is necessary to align the four sets of positioning rods 10 so that the four sets of positioning rods 10 can be inserted into the four sets of screw holes 31 respectively, thereby limiting and positioning the support plate 3. Then, the electric push rods 11 on both sides are activated, driving the clamping pressure plate 12 to descend until it presses and clamps both ends of the support plate 3, thereby clamping and positioning the entire caster frame assembly, enhancing the stability during installation, and effectively preventing the caster frame assembly from shifting during the rotation of the feeding turntable of the riveting machine.

[0023] After clamping and fixing, the feeding turntable will rotate to move the assembly to the stamping area of ​​the riveting machine to stamp the rivet 4 and form a riveting structure.
