Description

Technical Field

[0001] This utility model belongs to the field of hydraulic cylinder assembly technology, specifically relating to an assembly device for rapid positioning of hydraulic cylinders. Background Technology

[0002] Hydraulic cylinders are the core actuators in hydraulic systems. Their core function is to convert the pressure energy of hydraulic oil into mechanical energy to drive the load to achieve linear motion or generate thrust.

[0003] Hydraulic cylinder assembly is the process of gradually assembling the core components of a hydraulic cylinder, such as the cylinder barrel, piston, piston rod, seals, end caps, and buffer devices, into a complete and normally functioning hydraulic actuator according to design process and precision requirements.

[0004] During the assembly process, the workers need to place the cylinder body on the fixture first. The existing support method is to support the cylinder body with the rollers below and then clamp the cylinder body. However, the support of the cylinder body by the rollers is not stable enough and the cylinder body is prone to slipping. Utility Model Content

[0005] The purpose of this invention is to provide an assembly device for rapid positioning of hydraulic cylinders, so as to solve the problem that existing hydraulic cylinders are not stable enough during installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An assembly device for rapid positioning of a hydraulic cylinder includes a worktable. The end face of the worktable is provided with a clamp, a cylinder body, a placement platform, and a pressing plate. The end face of the placement platform is provided with a shaft. The end face of the worktable is provided with an auxiliary mechanism, which includes a telescopic mechanism mounted on the end face of the worktable. The output end of the telescopic mechanism is fixedly connected to a fixed plate. The end face of the fixed plate is fixedly connected to a stop rod and two support rods. The top ends of the two support rods are fixedly connected to a first arc plate. One end of the first arc plate is fixedly connected to a rectangular plate. A rotating rod is rotatably connected to the surface of the rectangular plate. Two connecting plates are fixedly connected to the arc surface of the rotating rod. A second arc plate is fixedly connected to the side of the two connecting plates that are close to each other.

[0008] Preferably, both the arc surfaces of the first and second arc plates are provided with grooves, and the inner walls of the grooves are rotatably connected to multiple rollers.

[0009] Preferably, the rectangular plate has two grooves on its end face, and the inner walls of the two grooves are slidably connected to sliders. The end faces of the two sliders are fixedly connected to baffles. A rack is provided below the baffles, and the teeth of the rack mesh with gears. The gears are fixedly connected to the arc surface of the rotating rod.

[0010] Preferably, the rectangular plate has a rectangular hole on its surface, the gear is located inside the rectangular hole, the bottom surface of the baffle is fixedly connected to a vertical plate, and the rack is fixedly connected to the bottom end of the vertical plate.

[0011] Preferably, a spring is fixedly connected to the surface of the slider, and the other end of the spring is fixedly connected to the inner wall of the groove.

[0012] Preferably, the cross-sectional shape of the baffle is trapezoidal.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses a first arc plate to support the cylinder body. The first arc plate is designed in an arc shape to better fit the curved surface of the cylinder body, thereby improving the stability of the cylinder body support. By setting an expandable second arc plate on the first arc plate, the stability of the cylinder body is further improved. By setting multiple rollers inside the first and second arc plates, the friction can be reduced when the cylinder body rotates.

[0015] This invention, by setting a baffle, allows the baffle to retract when the cylinder is placed, and then, through the cooperation of gears and racks, the second arc plate automatically covers the first arc plate, making operation more convenient. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-5 As shown, this utility model provides an assembly device for rapid positioning of hydraulic cylinders, including a workbench 1. The end face of the workbench 1 is provided with a clamp 101, a cylinder body 102, a placement platform 103, and an extrusion plate 105. The end face of the placement platform 103 is provided with a shaft 104.

[0024] In this embodiment, the clamp 101 is prior art, consisting of a motor, a threaded rod, and clamping blocks. The clamping blocks are threadedly connected to the threaded rod. The motor drives the threaded rod to rotate, causing the two clamping blocks to move closer together to achieve the clamping effect. This is a technology well-known to those skilled in the art and will not be described in detail here. The extrusion plate 105 is prior art. Specifically, its movement is achieved by another motor driving another screw to rotate. The extrusion plate 105 is threadedly connected to the screw, thus moving the extrusion plate 105. This is a technology well-known to those skilled in the art and will not be described in detail here.

[0025] An auxiliary mechanism 2 is provided on the end face of the workbench 1. The auxiliary mechanism 2 includes a telescopic mechanism 201 installed on the end face of the workbench 1. A fixed plate 202 is fixedly connected to the output end of the telescopic mechanism 201. A stop bar 2021 and two support rods 203 are fixedly connected to the end face of the fixed plate 202. A first arc plate 204 is fixedly connected to the top of the two support rods 203. A rectangular plate 205 is fixedly connected to one end of the first arc plate 204. A rotating rod 206 is rotatably connected to the surface of the rectangular plate 205. Two connecting plates 207 are fixedly connected to the arc surface of the rotating rod 206. A second arc plate 208 is fixedly connected to the side of the two connecting plates 207 that are close to each other.

[0026] In this embodiment, the telescopic mechanism 201 is existing technology, which is an electric telescopic rod and is well known to those skilled in the art. It will not be described in detail here. The stop bar 2021 has the effect of limiting and blocking the second arc plate 208. That is, after the second arc plate 208 is flipped open, the second arc plate 208 will be blocked by the stop bar 2021, thereby limiting the position of the second arc plate 208.

[0027] In an optional embodiment: both the arc surface of the first arc plate 204 and the arc surface of the second arc plate 208 are provided with grooves 209, and the inner wall of the grooves 209 is rotatably connected to a plurality of rollers 210.

[0028] It should be noted that roller 210 serves to reduce friction.

[0029] In an optional embodiment: two grooves 213 are formed on the end face of the rectangular plate 205, and sliders 214 are slidably connected to the inner walls of the two grooves 213. Baffles 215 are fixedly connected to the end faces of the two sliders 214. A rack 218 is provided below the baffle 215. A gear 212 is meshed on the tooth surface of the rack 218. The gear 212 is fixedly connected to the arc surface of the rotating rod 206. A rectangular hole 211 is formed on the surface of the rectangular plate 205. The gear 212 is located inside the rectangular hole 211. A vertical plate 217 is fixedly connected to the bottom surface of the baffle 215. The rack 218 is fixedly connected to the bottom end of the vertical plate 217. A spring 216 is fixedly connected to the surface of the slider 214. The other end of the spring 216 is fixedly connected to the inner wall of the groove 213.

[0030] It should be noted that the cross-sectional shape of the baffle 215 is trapezoidal, and the side of the baffle 215 that is being squeezed is inclined and will slide. That is, in the initial state, before the cylinder 102 is placed into the first arc plate 204, the baffle 215 protrudes a section, which can block the cylinder 102. By pressing the baffle 215 down on the cylinder 102, the gear 212 and the rack 218 are driven to achieve the function of automatically flipping the second arc plate 208.

[0031] The working principle of this utility model is as follows: In use, the operator first clamps the cylinder 102 with the clamp 101 and places the cylinder 102 on the first arc plate 204. The cylinder 102 will press against the baffle 215. The side of the baffle 215 that is pressed is inclined and will slide. The spring 216 is in a deformed state, and the rack 218 will move with the movement of the baffle 215 and mesh with the gear 212, causing the gear 212 to drive the rotating rod 206 to rotate. Then the second arc plate 208 will flip until the cylinder 102 falls completely into the first arc plate 204. At this time, the baffle 215 stops moving. Under the influence of gravity, the arc plate 208 will continue to rotate. At this time, the rack 218 will not mesh with the gear 212. The gear 212 will continue to rotate without affecting the rack 218 until the roller 210 on the second arc plate 208 contacts the cylinder 102. Then, the clamp 101 can be started by the external controller to clamp the cylinder 102. After clamping, the extrusion plate 105 is moved by the external controller to extrude the shaft 104, causing the shaft 104 to move into the cylinder 102. After the shaft 104 is inserted into the cylinder 102, the clamp 101 is rotated to make the cylinder 102 rotate, thus achieving the effects of hole alignment and interface positioning.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
