Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinder assembly equipment, in particular to a hydraulic oil cylinder assembly work platform. Background Art

[0002] The assembly of the hydraulic cylinder piston rod is a key process in the production of hydraulic cylinders. Currently, there is no special tooling suitable for guiding and positioning the piston rod during the assembly process. Operators use manual positioning. A slight deviation or bump during the assembly process will cause scratches or damage to the hydraulic cylinder barrel or piston rod seal, affecting the air tightness of the hydraulic cylinder sealing chamber, causing hydraulic oil leakage and the hydraulic cylinder to be scrapped.

[0003] In order to facilitate the assembly of the hydraulic rod, the patent authorization announcement number CN218169375U was published. By setting the guide sleeve and the sleeve mouth to be a cylindrical structure, the inner walls of the guide sleeve and the sleeve mouth are on the same plane. When in use, firstly, the end of the guide sleeve away from the sleeve mouth is abutted against the inlet end of the cylinder barrel, and the inner wall diameter of the guide sleeve matches the inner wall diameter of the cylinder barrel. At this time, the fixing plates on both sides are covered on the outer wall of the cylinder barrel, and two locking bolts are moved to fix the two fixing plates to the outer wall of the cylinder barrel, which is convenient for positioning and fixing the guide sleeve and the sleeve mouth, and then one end of the piston rod is removed from The sleeve enters through the guide sleeve and finally enters the cylinder barrel to complete the assembly. The inner wall of the sleeve end away from the guide sleeve is a smooth chamfer, which makes it easier for the piston rod to enter the sleeve, making the piston rod assembly smoother and more convenient, and avoiding damage to the piston rod. Because it is fixed and positioned by two fixing plates, the fixing effect is good, which is convenient for piston rod assembly and improves assembly efficiency. There is no need to have excessively high requirements on the overall accuracy of the guide sleeve, which reduces the processing cost. Therefore, it can be seen that the current hydraulic cylinder assembly work platform basically meets people's needs, but there are still some problems.

[0004] However, during the assembly of the hydraulic cylinder, firstly, it is limited by the threads on both sides. In this way, it is difficult to ensure that the workpiece is in the center position. Secondly, the bolts on both sides need to be rotated separately, so that it is relatively stable during use. In addition, the contact area is small due to the limitation of the bolts, which makes it difficult to clamp stably, resulting in low overall stability of the device. Therefore, a hydraulic cylinder assembly work platform is urgently needed to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 The utility model provides an embodiment: a hydraulic cylinder assembly work platform, including a base 111, the top of the base 111 is fixedly connected with four groups of connecting rods 112, and the top of the connecting rods 112 is fixedly connected with a guide sleeve 113, and a clamping mechanism is provided on the base 111, and the clamping mechanism includes a clamping plate 211, and the clamping plates 211 are provided on both sides of the inside of the base 111, and the clamping plates 211 are fixedly connected on both sides of the outside of the clamping plates 211. The clamping blocks 212 are clamped in the inside of the base 111. This design can make the movement of the clamping plate 211 It can be more stable, and the instability of clamping will not be caused by uneven force during clamping. A limiting groove 216 that cooperates with the clamping block 212 is provided on the base 111, and the left and right sides of the top of the base 111 are movably connected with a threaded rod 213 through a bearing, and the two sides of the outside of the threaded rod 213 are provided with symmetrically distributed threads. The two groups of clamping plates 211 are respectively connected to the two sides of the outside of the threaded rod 213 through threads. This design makes it easy to rotate the threaded rod 213 to make the clamping plates 211 on both sides move synchronously, thereby clamping and limiting.

[0024] Furthermore, one end of the threaded rod 213 extends outside the fixing block 215 , and a rotating handle 214 is fixedly connected to the end of the fixing block 215 . This design makes it easier to rotate the threaded rod 213 .

[0025] Furthermore, a limiting mechanism is provided on the clamping plate 211, and the limiting mechanism includes an arc plate 311, and the arc plate 311 is fixedly connected to the ends of the two groups of clamping plates 211 that are close to each other, and a main clamping plate 315 is provided in the middle of the side where the two groups of arc plates 311 are close to each other, and the two sides of the two groups of main clamping plates 315 that are far away from each other are fixedly connected with a plug rod 318, and the plug rod 318 extends into the interior of the arc plate 311, and a slot 317 that cooperates with the plug rod 318 is opened inside the arc plate 311. This design allows the plug rod 318 to be engaged when it is engaged. The clamping is more compact and stable after being inserted into the slot 317, a first spring 316 is welded on the end of the two sets of main splints 315 away from each other, and the other end of the movable support rod 312 is welded on the arc plate 311, and the two sides of the two sets of arc plates 311 close to each other are movably connected with the movable support rod 312 through a hinge axis, and the end of the movable support rod 312 away from the arc plate 311 is fixedly connected to the auxiliary splint 313. This design makes it easy to perform synchronous clamping through the main splint 315 and the auxiliary splint 313, thereby making it more stable when clamping.

[0026] Furthermore, three groups of first springs 316 are respectively provided on both sides, and the three groups of first springs 316 are evenly distributed on the main splint 315. This design makes it easy to assist in limiting the main splint 315 through the first springs 316, so that its position is more stable.

[0027] Furthermore, a limiting rod 319 is fixedly connected to one side of the auxiliary splint 313 close to one end of the arc plate 311, and a second spring 320 is welded to the other side of the auxiliary splint 313 close to one end of the arc plate 311, and the other end of the second spring 320 is welded to the arc plate 311.

This design can make the anti-skid effect better and make the clamping more stable.

[0029] Working principle: when the oil cylinder needs to be assembled, first place the workpiece in the middle of the device so that it is placed between the two sets of clamping plates 211, and then turn the rotating handle 214. When the rotating handle 214 is turned, the threaded rod 213 will be driven to rotate. When the threaded rod 213 rotates, the clamping plate 211 is threadedly connected to the threaded rod 213, and the threads on both sides of the threaded rod 213 rotate in opposite directions. At the same time, the clamping plate 211 is limited by the block 212, so that the clamping plates 211 on both sides are close to each other. When the clamping plates 211 on both sides are close to each other, the workpiece can be clamped and limited, and the workpiece is placed in the middle of the top of the base 111. When it needs to be taken out, the rotating handle 214 can be rotated in the opposite direction.

[0030] When clamping a larger cylinder, the outer wall of the cylinder will abut against the main clamping plates 315 on both sides, thereby causing the first spring 316 to deform, causing the main clamping plates 315 to move toward the side close to the arc plate 311. At this time, the two sides of the outer wall of the cylinder will respectively abut against one side of the anti-slip pads 314 on both sides, thereby causing the anti-slip pads 314 to rotate around the end of the movable support rod 312, thereby causing one side of the anti-slip pad 314 to abut against the outer wall of the workpiece, thereby limiting the position again and completing the clamping.
