Description

Technical Field

[0001] The utility model relates to the technical field of caster production, in particular to a feeding and assembling device for caster shaft sleeves and middle sleeves. Background Technique

[0002] Casters are a general term, including swivel casters, fixed casters and swivel casters with brakes. Swivel casters, also known as universal wheels, have a structure that allows 360-degree rotation; fixed casters, also called directional casters, have no rotating structure and cannot rotate. Usually, these two types of casters are generally used in combination. For example, the structure of a handcart is two directional wheels in the front and two universal wheels near the pushing armrest in the back. Casters are available in various materials, such as pp casters, PVC casters, PU casters, cast iron casters, nylon casters, TPR casters, iron core nylon casters, iron core PU casters, etc.

[0003] According to a feeding and assembling device for caster shaft sleeves and middle sleeves disclosed in the patent publication number CN 211966537 U, this device realizes the automatic feeding and assembling of the middle sleeve and the shaft sleeve, thus greatly saving manpower and improving production efficiency. However, when clamping and fixing the middle sleeve, the fixing effect is poor, and the middle sleeve may slide after being fixed, thus affecting the subsequent assembling operation.

[0004] Therefore, we propose a feeding and assembling device for caster shaft sleeves and middle sleeves to solve the problem. Content of the Utility Model

[0027] Embodiment 1

[0028] As Figures 1-5 shown, the present utility model provides a technical solution: a caster sleeve and middle sleeve feeding and assembling device, including a conveyor device 1, a mounting frame 2 fixedly installed on the upper part of the conveyor device 1, a vibration disk 4 fixedly installed on the upper part of the mounting frame 2, a first hydraulic cylinder 5 fixedly installed on the side wall of the conveyor device 1, and a connecting component 3 arranged on the upper part of the conveyor device 1. The connecting component 3 includes a fixing mechanism 31 arranged on the upper part of the conveyor device 1, and an alignment mechanism 32 arranged on the upper part of the conveyor device 1. The fixing mechanism 31 includes a cylinder 311 fixedly installed on the upper part of the mounting frame 2. The output end of the cylinder 311 is fixedly connected with a rectangular plate 312. A connecting column 313 is movably connected inside the rectangular plate 312. The top end of the connecting column 313 is fixedly connected with a first limiting block 314. The bottom end of the first limiting block 314 is fixedly connected with a first spring 315. The bottom end of the connecting column 313 is fixedly connected with a mounting plate 316. A discharge box 317 is fixedly installed at the bottom of the mounting plate 316. A sleeve feeding cylinder 318 is communicated with the upper part of the discharge box 317. The output end of the first hydraulic cylinder 5 is fixedly connected with a fixing plate 319. A convex groove 3110 is opened on the inner side of the fixing plate 319. A convex column 3111 is slidably connected to the inner wall of the convex groove 3110. A connecting plate 3112 is fixedly connected to the outside of the convex column 3111. An anti-slip plate 3113 is fixedly connected to the outside of the connecting plate 3112. The upper part of the fixing plate 319 is rotatably connected with a rotating rod 3114 through a bearing. One end of the rotating rod 3114 is movably connected with a clamping rod 3115. The top end of the clamping rod 3115 is fixedly connected with a second limiting block. A second spring 3116 is fixedly connected to the upper part of the rotating rod 3114. A clamping groove 3117 is opened on the upper part of the fixing plate 319. A discharge hole is opened at the bottom of the discharge box 317.

[0029] In this embodiment, the top end of the first spring 315 is fixedly connected to the first limiting block 314, and the top of the bushing feeding cylinder 318 is movably connected to the mounting bracket 2. Through the cooperation of the connecting column 313, the first limiting block 314, the first spring 315, the rectangular plate 312, and the mounting plate 316, when assembling the workpiece, a buffering effect can be achieved, thereby preventing excessive pressure from damaging the workpiece.

[0030] Furthermore, the top end of the second spring 3116 is fixedly connected to the second limiting block, and the clamping rod 3115 is clamped with the clamping groove 3117. The middle sleeve can be clamped and fixed by the fixing plate 319 and the first hydraulic cylinder 5. And by setting the anti-slip plate 3113, the workpiece can be made not to slide easily after being fixed, thus making the subsequent assembly operation more convenient. At the same time, through the cooperation of the convex groove 3110, the convex column 3111, the connecting plate 3112, the rotating rod 3114, the clamping rod 3115, the second spring 3116, and the clamping groove 3117, it is convenient for manual replacement of the anti-slip plate 3113 with larger wear, so as to achieve a better fixing effect on the middle sleeve.

[0031] When the device is in use, the bushing is placed in the vibrating bowl 4, and the vibrating bowl 4 is used for feeding, so that the bushings slide one by one to the bushing feeding cylinder 318. The bushing slides down along the bushing feeding cylinder 318 into the discharge box 317, and then can be discharged through the discharge hole of the discharge box 317. The first hydraulic cylinder 5 drives the fixing plate 319 to clamp and fix the middle sleeve. Thus, when the bushing falls into the middle sleeve, the first hydraulic cylinders 5 on both sides drive the middle sleeve to move relatively, so that the middle sleeve and the bushing are far away from the discharge hole provided at the bottom of the discharge box 317. Then, the cylinder 311 drives the rectangular plate 312 to move downward. Under the action of the connecting column 313 and the first limiting block 314, the mounting plate 316 fixedly connected to the bottom end of the connecting column 313 can move downward synchronously, so that the discharge box 317 can be pressed downward, and then the assembly operation of the workpiece can be carried out. Furthermore, when it is necessary to disassemble the anti-slip plate 3113, only need to manually pull the clamping rod 3115 outward to make the clamping rod 3115 away from the clamping groove 3117. Then, manually rotate the rotating rod 3114 to make the rotating rod 3114 away from the upper part of the convex column 3111. Then, the connecting plate 3112 can be taken out upward manually, so as to facilitate the manual replacement of the anti-slip plate 3113 with larger wear in time, so as to achieve a better fixing effect on the middle sleeve.

An installation block 321 is fixedly connected to the inner wall of the conveying device 1. A alignment plate 322 is movably connected to the inside of the installation block 321 through a pin. A chute 323 is provided on one side of the alignment plate 322. A slide bar 324 is fixedly connected to the inner wall of the chute 323. A slider 325 is slidably connected to the outer wall of the slide bar 324. A fixed block 326 is fixedly connected to the outside of the slider 325. A connecting block 327 is movably connected to the inside of the fixed block 326 through a pin.

[0034] In this embodiment, the output end of the second hydraulic cylinder 328 is fixedly connected to the connecting block 327.

[0035] Furthermore, there are two alignment plates 322, which are symmetrically distributed inside the conveying device 1.

[0036] When it is necessary to adjust the alignment plate 322, the second hydraulic cylinder 328 drives the connecting block 327 to move inward, so that the connecting block 327 can press the fixed block 326 inward. Since the connecting block 327 is rotatably connected to the fixed block 326 through a pin and under the action of the slide bar 324 and the slider 325, the fixed block 326 can press the alignment plate 322 inward. At the same time, since the alignment plate 322 is rotatably connected to the installation block 321 through a pin, the angle of the alignment plate 322 can be adjusted, and the distance between the two alignment plates 322 can be adjusted, so that workpieces of different sizes can be aligned, and the subsequent assembly operation of the workpieces is made more convenient.
