Description

Technical Field

[0001] This utility model relates to the field of caster manufacturing technology, and more specifically, to a bracket for caster manufacturing. Background Technology

[0002] Casters are a general term that includes swivel casters, fixed casters, and swivel casters with brakes. Swivel casters, also known as universal wheels, have a structure that allows them to rotate 360 ​​degrees. Fixed casters, also called directional casters, do not have a rotating structure and cannot be rotated. In order to facilitate the production and assembly of casters, they need to be equipped with special brackets.

[0003] However, in the existing technology, caster bracket fixtures are generally fixed by pressing from top to bottom, and the position cannot be adjusted, which causes inconvenience to the assembly of casters and makes it difficult to switch the caster bracket fixture between multiple workstations, thus reducing the production and assembly efficiency of casters. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a caster manufacturing bracket that is suitable for clamping and assembling casters of different sizes and maintaining assembly stability, thereby solving the problems mentioned in the background technology.

[0006] (II) Technical Solution

[0007] To achieve the advantages of clamping, assembling, and maintaining assembly stability of casters of different sizes, the specific technical solution adopted by this utility model is as follows: A caster production bracket includes a base and an assembly turntable above it. A rotating shaft is rotatably mounted on the top of the base via a bearing seat, and an assembly turntable is fixed on the top of the rotating shaft. Several unit bearing plates are arranged around the side of the assembly turntable, and a positioning seat is installed on the top of each unit bearing plate. A threaded post is fixed to the bottom of the positioning seat, and a nut is threaded through the unit bearing plate. Protruding posts are welded to the four corners of the top surface of the positioning seat. A support block is fixed to the surface of the unit bearing plate corresponding to the positioning seat, and a swivel knob is threaded onto the surface of the support block.

[0008] Furthermore, each of the unit support plates has a positioning hole on its surface, a mounting base is welded to the inner side of the base, and an electric push rod is fixed to the top surface of the mounting base. The top of the electric push rod passes through the base and is fixed with a positioning post, and the positioning post corresponds to the positioning hole of one of the unit support plates.

[0009] Furthermore, the base is an inverted U-shaped structure, and a circular clearance hole is provided on the top surface of the base corresponding to the electric push rod.

[0010] Furthermore, the protrusions of the positioning seat are all cylindrical in shape, and the surface of each protrusion is covered with a rubber sleeve.

[0011] Furthermore, the support block is located at half the width of the unit bearing plate, and the surface of the support block has screw holes corresponding to the plum blossom knob.

[0012] Furthermore, each unit bearing plate has a handle welded to both its left and right sides, and each unit bearing plate has mounting holes corresponding to the threaded posts on its surface.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a bracket for caster production, which has the following advantages:

[0015] (1) This utility model adopts an assembly turntable that is rotatably installed on the base via a rotating shaft, and several unit bearing plates are arranged around the side of the assembly turntable. By rotating the assembly turntable, the several unit bearing plates are switched sequentially at the caster assembly station, loading station and unloading station. On this basis, a positioning seat with several protrusions is detachably installed on each unit bearing plate. By placing the caster between the protrusions and rotating the plum blossom knob on the support block, the plum blossom knob abuts against the caster on the positioning seat.

[0016] (2) In this utility model, an installation seat, an electric push rod and a positioning column are provided on the inner side of the inverted U-shaped base. As the rotating shaft drives the assembly turntable to adjust the position of several unit bearing plates, when any unit bearing plate is parallel to the base, the electric push rod is activated to extend, causing the electric push rod to push the positioning column to insert into the positioning hole on the surface of the unit bearing plate, thereby locking the position of the unit bearing plate and preventing the unit bearing plate from shifting on its own. This is beneficial to increasing the stability of the casters during the assembly stage. Attached Figure Description

These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a bracket for caster production is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, a caster production support according to an embodiment of the present invention includes a base 1 and an assembly turntable 2 above it. A rotating shaft 11 is rotatably mounted on the top of the base 1 via a bearing seat, and the assembly turntable 2 is fixed on the top of the rotating shaft 11. Several unit bearing plates 3 are arranged around the side of the assembly turntable 2, and a positioning seat 4 is installed on the top of each unit bearing plate 3. A threaded post 6 is fixed on the bottom of the positioning seat 4, and the threaded post 6 is threaded through the unit bearing plate 3 and connected to a nut 7. The four corners of the top surface of the positioning seat 4 are welded with protruding posts 5. A support block 8 is fixed on the surface of the unit bearing plate 3 corresponding to the positioning seat 4, and a plum blossom knob 9 is threaded on the surface of the support block 8. In order to fit the assembly turntable 2, the caster assembly station, the loading station and the unloading station are arranged around the assembly turntable 2. The rotation of the assembly turntable 2 is mainly manually adjusted by a lever 10.

[0027] In one embodiment, each unit support plate 3 has a positioning hole 15 on its surface. A mounting base 12 is welded to the inner side of the base 1, and an electric push rod 13 is fixed to the top surface of the mounting base 12. The top of the electric push rod 13 passes through the base 1 and is fixed with a positioning post 14. The positioning post 14 corresponds to the positioning hole 15 of one of the unit support plates 3. This structure prevents the unit support plate 3 from shifting on its own and helps to increase the stability of the casters during the assembly stage. The electric push rod 13 is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring arrangement will not be explained in detail.

[0028] In one embodiment, the base 1 is an inverted U-shaped structure, and the top surface of the base 1 is provided with a circular clearance hole corresponding to the electric actuator 13. This structure makes it easy to provide installation space for the electric actuator 13 and make way for it.

[0029] In one embodiment, the protrusions 5 of the positioning seat 4 are all cylindrical in shape, and the surface of each protrusion 5 is covered with a rubber sleeve. This structure increases the elasticity of the protrusion 5 in contact with the caster and prevents damage.

[0030] In one embodiment, the support block 8 is located at half the width of the unit bearing plate 3, and the surface of the support block 8 has a screw hole corresponding to the plum blossom knob 9. With this structure, it is easy for the plum blossom knob 9 to extend between several protrusions 5 of the positioning seat 4, so as to satisfy the clamping and fixing of the caster.

[0031] In one embodiment, each unit support plate 3 is welded with a handle 10 on both the left and right sides, and each unit support plate 3 has a mounting hole corresponding to the threaded post 6 on its surface. The handle 10 facilitates manual rotation of the unit support plate 3, and the mounting hole facilitates the installation and removal of the positioning seat 4.

[0032] Working principle: First, the device is installed at the caster assembly position. By rotating the assembly turntable 2 above the base 1, several unit bearing plates 3 are sequentially switched between the caster assembly station, the loading station, and the unloading station. On this basis, each unit bearing plate 3 is detachably installed with a positioning seat 4 with several protrusions 5. By placing the caster between the protrusions 5 and rotating the plum blossom knob 9 on the support block 8, the plum blossom knob 9 abuts against the caster on the positioning seat 4, which can satisfy the clamping of casters of different sizes and facilitate the quick assembly of casters. At the same time, as the rotating shaft 11 drives the assembly turntable 2 to adjust the position of several unit bearing plates 3, when any unit bearing plate 3 is parallel to the base 1, the electric push rod 13 is activated to extend, causing the electric push rod 13 to push the positioning column 14 to insert into the positioning hole 15 on the surface of the unit bearing plate 3, thereby locking the position of the unit bearing plate 3 and preventing the unit bearing plate 3 from shifting, which helps to increase the stability of the caster during the assembly stage.
