Description

TECHNICAL FIELD

[0001] The utility model relates to a device for assembling bushings in a wide range. BACKGROUND

[0002] The use of bushings can reduce the wear, vibration and noise of equipment. With the development of the mechanical manufacturing industry, bushings are widely used in aerospace, shipbuilding engineering, automobile manufacturing and other fields. When assembling bushings, the pressing tool used for bushings requires high precision.

[0003] A device and method for assembling bushings by a bench worker are disclosed in a Chinese patent (Grant Announcement No. CN 220074584U). The patented technology can install bushings at low cost without manual installation. However, the installation method is still hammering, which is not effective and cannot effectively control the installation position of the bushing. Therefore, a device for assembling bushings by a bench worker is provided by a person skilled in the art to solve the problems raised in the above background technology. SUMMARY

[0004] The purpose of the utility model is to provide a device for assembling bushings by a bench worker to solve the problems raised in the above background technology.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] A device for assembling bushings by a bench worker, comprising a device body, the device body comprising a workbench, a processing device and a hydraulic propelling machine, the workbench comprising a workbench body, the workbench body bottom side being provided with a plurality of workbench support columns, the workbench body top being provided with a screw rod, the screw rod being gap fitted with the workbench body, the screw rod two sides being provided with a fixed rod, the screw rod edge side near the workbench body being provided with a distance control wheel, the screw rod other side being gap fitted with a screw rod support rod, the screw rod being provided with a fixed washer on both sides of the screw rod support rod, the screw rod being internally threadedly engaged with a carrier sliding block, the carrier sliding block being gap fitted with the fixed rod, the distance control wheel being rotated, the carrier sliding block being internally engaged with the screw rod, but due to the action of the fixed rod, the distance between the two carrier sliding blocks will be contracted or expanded, thereby achieving the effect of controlling the distance between the two processing devices.

[0007] Preferably: the carrier slider is equipped with a processing device, the processing device including a motor, the motor having wires connected to a power source, and a drive gear at the other end of the motor. The drive gear meshes with a driven gear, and the driven gear is clearance-fitted with a gear groove on the processing device housing. The processing device housing is fixedly connected to a support plate. The processing device housing and the support plate have a coarse mounting hole at the center of the processing device housing. The processing device housing is equipped with several structural rods, both ends of which are fixedly connected to two parts of the processing device housing. The structural rods are clearance-fitted with slots on a driven disc. The driven disc is fixedly connected to a driven gear and rotatably connected to one end of several connecting rods. The other end of the connecting rod is rotatably connected to the biting blade. The biting blade is rotatably connected to the outer shell of the processing device through the blade rotation shaft. The bushing, which is slightly larger in diameter than the object to be bushed, is installed in the coarse mounting hole of the right processing device. The right motor is started, the drive gear rotates and drives the driven gear to rotate. The driven gear drives the driven disc to rotate, and the slot and the structural rod move relative to each other. Under the transmission action of the connecting rod, the biting blade will shrink accordingly, so that the bushing and the biting blade are in transition fit. The object to be bushed is coarsely installed to the left processing device in the same way. When it is in the right position, the object to be bushed is inserted into the push hole of the hydraulic pusher. The left motor is started again, so that the biting blade and the object to be bushed are in clearance fit.

[0008] Preferably, the processing device has a hydraulic propeller on the left side, the hydraulic propeller has a hydraulic rod, and the hydraulic rod has a propulsion hole at its center. The propulsion hole is coaxial with the coarse mounting hole of the processing device. When the hydraulic propeller is started, the hydraulic rod pushes the workpiece closer to the processing device on the right. When it reaches the appropriate position, the hydraulic propeller is turned off and the power of the right motor is increased so that the biting blades and the bushing are interference-fitted, pressing the bushing onto the workpiece. This completes the bushing installation.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model uses a clamping method to install the bushing onto the object. This installation method can make the bushing more evenly stressed and avoid damage to the object or bushing caused by hammering.

[0011] 2. This utility model adopts a positioning method of manual coarse positioning and hydraulic precision positioning, which can accurately install the bushing to the designated position of the object. Attached Figure Description

[0022] Please see Figures 1-8In this embodiment of the utility model, a device for fitter to assemble bushings includes a device body 1. The device body 1 includes a workbench 2, a processing device 3, and a hydraulic propulsion machine 4. The workbench 2 includes a workbench body 212. The bottom side of the workbench body 212 is provided with a plurality of workbench support columns 211. A screw 213 is provided on the top of the workbench body 212. The screw 213 is clearance-fitted with the workbench body 212. Fixing rods 214 are provided on both sides of the screw 213. A distance control wheel 215 is provided on one side of the screw 213 near the edge of the workbench body 212. The other side of the screw 213 is clearance-fitted with a screw support rod 217. Fixing washers 218 are provided on both sides of the screw 213 and the screw 213 is threadedly engaged with a carrier slider 216. The carrier slider 216 is clearance-fitted with the fixing rods 214.

[0023] The carrier slider 216 is equipped with a processing device 3, which includes a motor 311. The motor 311 is equipped with a wire 313 connected to a power source. The other end of the motor 311 is equipped with a drive gear 312, which meshes with a driven gear 319. The driven gear 319 is clearance-fitted with a gear groove 324 on the processing device housing 315. The processing device housing 315 is fixedly connected to a support plate 314. The processing device housing 315 and the support plate 314 are provided with a central position on the processing device housing 315. The coarse mounting hole 317 is provided. The processing device housing 315 is provided with a plurality of structural rods 316. The two ends of the structural rods 316 are fixedly connected to two parts of the processing device housing 315 respectively. The structural rods 316 are clearance-fitted with the slots 321 on the driven disk 320. The driven disk 320 is fixedly connected to the driven gear 319. The driven disk 320 is rotatably connected to one end of a plurality of connecting rods 322. The other end of the connecting rod 322 is rotatably connected to the biting blade 323.

When the appropriate position is reached, the hydraulic pusher 4 is turned off and the power of the right motor 311 is increased to make the biting blade 323 fit with the bushing with interference fit, pressing the bushing onto the object. The bushing installation is thus completed.
