[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0025] Depend on Figure 1 As shown, it is a structural schematic diagram of the caster screw locking device in this embodiment, including a base 1, a control box 2, a screw locking body 3 and a placement mold 4. The control box 2 is installed on the surface of the base 1, and the screw locking body 3 for reinforcing the screw is installed on the side of the control box 2. The placement mold 4 is provided on the surface of the base 1, and a moving mechanism 5 is installed on the surface of the base 1 on the side of the placement mold 4.

[0026] During use, the casters that need to be reinforced are placed on the surface of the placement mold 4, and the locking screw body 3 and the control box 2 are used to tighten the casters. At this time, the other set of casters are placed on the other side of the placement mold 4 to realize double-station switching, shorten the waiting time when tightening the casters, and speed up the overall work efficiency. The moving mechanism 5 can assist the placement mold 4 to move stably and assist in switching the double stations.

[0027] By the attached Figure 2 As shown, the placement mold 4 includes a mold body 41 and a baffle 42. The mold body 41 is arranged on the upper surface of the base 1, and there are two groups of mold bodies 41. Connecting rods are installed between the mold bodies 41, and the baffle 42 is installed on one side of the upper surface of the mold body 41.

[0028] During use, the screw for subsequent reinforcement is first placed on the surface of the mold body 41, and then the caster is placed on the upper surface of the mold body 41 using the structure and shape of the mold body 41 itself. At this time, the screw penetrates the caster itself, and then the reinforced nut is installed on the outside of the screw by using the locking screw body 3 to realize the installation of the caster and ensure the stability of the caster itself.

[0029] By the attached Figure 2 As shown, a positioning groove 43 is provided inside the mold body 41 for sliding with the threaded rod passing through the caster. During use, the hexagonal rotating block at the bottom end of the screw is installed inside the positioning groove 43. The structure and shape of the positioning groove 43 itself are used to limit and support the bottom end of the screw to complete the positioning of the screw. Then, the caster is installed on the screw and positioned using the mold body 41 to complete the placement of the component.

[0030] By the attached Figure 3 As shown, it is a structural diagram of the placing mold 4 in this embodiment. The placing mold 4 also includes a pushing rack 44 and a blocking block 45. The pushing rack 44 is fixedly installed on the side of the baffle 42, and the blocking block 45 is symmetrically arranged on the upper surface of the base 1, and the side of the blocking block 45 is in contact with the pushing rack 44.

[0031] During use, the pushing rack 44 is pushed so that the two groups of mold bodies 41 can slide stably on the upper surface of the base 1. When the pushing rack 44 moves to the target position, the bottom end of the pushing rack 44 contacts the surface of the blocking block 45 to lock the position of the pushing rack 44, ensuring that one group of mold bodies 41 moves to the bottom of the locking screw body 3, which is convenient for the subsequent locking screw body 3 to tighten the bolt.

[0032] By the attached Figure 2 As shown, the moving mechanism 5 includes a moving frame 51 and a slide rail 52. The moving frame 51 is installed on the side of the mold 4, and the slide rail 52 is fixedly installed on the upper surface of the base 1. The slide rail 52 is slidably connected to the moving frame 51. During use, the mold body 41 drives the side moving frame 51 to slide outside the slide rail 52 through the push of the pushing frame 44, which is used to flexibly adjust the positions of the two groups of mold bodies 41. When the casters on the surface of one group of mold bodies 41 are receiving processing, the other group of mold bodies 41 is in an idle state, and the auxiliary equipment operates efficiently.

[0033] By the attached Figure 2 As shown, the moving mechanism 5 also includes a blocking plate 53, which is symmetrically installed on both sides of the slide rail 52. There are two groups of blocking plates 53. During use, the two groups of blocking plates 53 can limit the moving distance of the moving frame 51, preventing the moving frame 51 from sliding out from the outside of the slide rail 52, thereby ensuring the stability of the equipment during operation.

[0034] By the attached Figure 5As shown, it is a structural schematic diagram of the pushing mechanism 6 in this embodiment. The pushing mechanism 6 includes an electric push rod 61, a pushing rod 62 and a pushing plate 63. The electric push rod 61 is installed on the side of the control box 2, and the output end of the electric push rod 61 passes through the control box 2. The pushing rod 62 is installed at the output end of the electric push rod 61, and the pushing plate 63 is fixedly installed on the side of the pushing rod 62.

[0035] During use, when the locking screw body 3 is tightened for the caster, the control box 2 will send a signal to the electric push rod 61, the electric push rod 61 will start immediately, and the push rod 62 will push the push plate 63 to move to the side close to the mold body 41, and directly push out the processed caster to complete automatic unloading without the need for manual transportation and movement by staff.

[0036] By the attached Figure 5 As shown, a calibration plate is installed on the side of the control box 2 at the bottom of the pushing plate 63. The calibration plate is on the same horizontal line as the placed mold 4, and the pushing plate 63 is slidingly connected to the calibration plate. During use, the calibration plate can assist the pushing plate 63 in moving, ensuring that the pushing plate 63 can stably push the casters that have been processed on the surface of the mold body 41 when it moves.

[0037] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
