Description
Technical Field
[0001] The utility model belongs to the field of runout detection equipment, and in particular relates to a caster runout detection device. Background Art
[0002] In the production and assembly process of casters, since casters are composed of four parts: wheel frame, bearing, shaft core and wheel, defective products are inevitable in the process of separate production. Since these parts are mass-produced, it is difficult to check whether they are good products one by one during the production process. Therefore, these parts will be gathered together for centralized assembly. Due to the existence of defective products, various problems will definitely arise during the use of the assembled casters. The purpose of using casters is to ensure that the chairs or cabinets installed on them can maintain balance after several casters are assembled. Therefore, as long as the runout of the assembled casters is within a controllable range, the use requirements of the casters can be met. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides a caster runout detection device, which makes the caster to be detected abut against the conveyor belt on the upper end of the detection plate, and the conveyor belt drives the wheel on the caster to rotate. When the wheel is an eccentric wheel, the detection plate will be pushed open, so that the detection head can detect the runout of the detection plate, thereby knowing whether the caster to be detected meets the requirements.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A caster runout detection device comprises a detection platform and a mounting platform, wherein a detection assembly and a transmission assembly are provided on the detection platform, wherein the detection assembly comprises a fixed plate, a detection plate and a detection head, wherein the fixed plate is fixedly connected to the detection platform, a limit plate is provided on the upper end surface of the fixed plate, a counterweight is provided at one end of the detection plate, the other end of the detection plate abuts against the lower end of the limit plate, the middle part of the detection plate is rotatably connected to the fixed plate, the upper end surfaces of the fixed plate and the detection plate are flush, the detection head is connected to the detection platform and points to the detection plate abutting against one end of the limit plate; the transmission assembly comprises a motor, a transmission wheel and a conveyor belt, wherein the motor drives the transmission wheel to rotate, and the transmission wheel drives the conveyor belt to slide on the upper end surfaces of the fixed plate and the detection plate; the caster to be detected is detachably connected to the mounting platform, and the caster to be detected abuts against the conveyor belt located at the upper end of the detection plate.
[0006] A feeding assembly and a mounting assembly are provided on the mounting platform, and the feeding assembly includes a propulsion seat, a fixed seat and a lifting seat. The propulsion seat is connected to the mounting platform through the lifting seat, and the propulsion seat can be movably connected to the lifting seat. The fixed seat is a disc-shaped structure, and the end of the propulsion seat is connected to the center of the fixed seat. The fixed seat is provided with a plurality of fixing holes in a circular array; the mounting assembly includes a support rod, a mounting seat and an adjusting rod, one end of the support rod is connected to the mounting seat through the adjusting rod, and the other end of the support rod is detachably connected to the fixing hole, and the caster to be detected is detachably connected to the mounting seat.
[0007] In the caster jump detection device adopting this structure, the transmission component on the detection platform drives the transmission wheel through the motor, and the transmission wheel drives the conveyor belt for transmission, so that the conveyor belt slides on the upper end surface of the fixed plate and the detection plate, and the caster to be detected is abutted on the conveyor belt located at the upper end of the detection plate, and the conveyor belt drives the caster to be detected to rotate. When the caster to be detected is an eccentric wheel, jumping will occur during the rotation process, and the jumping caster to be detected will be pushed on the detection plate. Since the middle part of the detection plate is rotatably connected to the fixed plate, a counterweight block is provided at one end of the detection plate, and the other end of the detection plate is abutted on the lower end of the limit plate, the caster to be detected abuts on the rotating part of the detection plate and the area between the limit plates. Therefore, the jumping caster to be detected pushes the detection plate, and the detection plate will move When pressed down, the end of the detection plate at the limit plate will move downward, and a distance sensor is set in the detection head. After detecting the movement of the detection plate, the runout degree of the caster to be detected can be learned. The farther the position where the caster to be detected abuts against the detection plate is from the position indicated by the detection head, the slight runout will be magnified, and the detection head can more easily obtain the runout degree of the caster to be detected. The purpose of setting the counterweight block is to provide continuous upward supporting force for the detection plate, keeping one end of the detection plate continuously abutting against the limit plate. After the eccentric caster to be detected pushes the detection plate, the detection plate can still return to its original position. In order to detect the runout degree of the caster, the caster needs to be fixed in a specific position and remain motionless. Only when the wheel is driven to rotate on the conveyor belt can the runout degree be effectively detected.
[0008] In order to fix the casters, a feed assembly and a mounting assembly are set on the mounting table. The lifting seat on the feed assembly is used to lift the propulsion seat thereon up and down in the z-axis direction, while the propulsion seat pushes the fixed seat to adjust in the x-axis direction. The fixing holes on the fixed seat are used to install the support rod extending to the conveyor belt. The support rod is connected to the mounting seat through an adjusting rod. The caster to be detected is connected to the mounting seat. Because the models and sizes of the casters are inconsistent, it is necessary to adjust the abutment between the installed caster and the support plate. The setting of the adjusting rod is precisely used to adjust the abutment distance between the caster and the support plate. In order to be suitable for caster runout detection at various angles, a number of circular array fixing holes are set on the fixed seat. The support rod is installed on different fixing holes. The casters can be detected at different angles. At the same time, it can also be adapted to casters of various heights. The propulsion seat can adjust the distance between the caster and the position indicated by the detection head.
[0009] Furthermore, the detection assembly also includes a C-shaped seat, which is detachably connected to the detection table, the detection head is arranged at the upper end of the C-shaped seat, and the lower end of the C-shaped seat is arranged below the detection plate and does not contact the detection plate.
[0010] Compared with the prior art, the advantages of the utility model are: the runout of the caster to be detected is detected by a rotatable detection plate, the farther the position where the caster to be detected abuts against the detection plate is from the position indicated by the detection head, the slight runout will be magnified, and the detection head can more easily obtain the runout of the caster to be detected, and the arrangement of the feed assembly and the mounting assembly on the mounting table can be adapted to the installation of casters of different models and sizes, so that the caster runout detection device can detect casters of different models.
