Description
Technical Field
[0001] This utility model relates to the field of electric cylinder technology, specifically a multi-stage dual-speed electric cylinder. Background Technology
[0002] Electric cylinders are products specifically designed for continuous motion, low to high loads (usually high speed), and can be used multiple times during their service life. These products have extremely high positioning accuracy and controllability, and can achieve precise motion control under loads ranging from a few kilograms to 50 tons. Multi-stage dual-speed electric cylinders are one of the most widely used types of electric cylinders, with the advantages of multi-stage extension and speed change.
[0003] The existing multi-stage dual-speed electric cylinders have the following drawbacks during use: When connecting and fixing the end of the electric cylinder to the end of the target, there is usually an angle difference, resulting in a low fit between the electric cylinder and the target during installation. This makes them prone to wear and damage during subsequent production. In addition, when installing the electric cylinder, the connecting parts on the electric cylinder are inconsistent with the hole diameter of the target, causing loosening during fixing. Therefore, it is necessary to replace the connecting parts on the electric cylinder. However, the replacement of the connecting parts involves many procedures and is troublesome. Utility Model Content
[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0005] Therefore, the technical solution adopted by this utility model is as follows: a multi-stage dual-speed electric cylinder, comprising: a main body module and an adapter module, wherein the adapter module includes an annular component fitted on the main body module, a base fixed on the outer surface of the annular component, a limiting component movably mounted on the main body module and extending into the main body module, a fixing component slidably mounted on the base, a fixing block fitted on the base, and a fixing bolt extending through the fixing block into the base.
[0006] Preferably, the main module includes an electric cylinder body and a telescopic rod with one end disposed inside the electric cylinder body and the other end extending out of the electric cylinder body.
[0007] Preferably, an annular groove is formed on the end of the telescopic rod, and a T-shaped groove is formed on the outer side of the telescopic rod, with the bottom end of the T-shaped groove communicating with the annular groove.
[0008] Preferably, the annular component is fitted into the annular groove, and the limiting component is installed in the T-groove.
[0009] Preferably, the limiting component includes a T-shaped piece movably disposed within the T-slot, a spring connecting the bottom end of the T-shaped piece to the bottom wall of the T-slot, and a lifting rod hinged at the top end of the T-shaped piece.
[0010] Preferably, the outer surface of the annular component has slots arranged in a circular array, and the slots are interlocked with the T-shaped component.
[0011] Preferably, a groove is formed on the outer side of the base, and a screw hole is formed on the inner wall of the groove.
[0012] Preferably, the fixing component includes a slider that is slidably fitted into a groove and a connector integrally fixed to the end of the slider.
[0013] Preferably, the fixing block and the sliding groove are fitted together, and the fixing bolt passes through the fixing block and engages in the screw hole.
[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:
[0015] 1. In this utility model, an annular groove is opened on the end of the telescopic rod, and an annular component is embedded in the annular groove. The annular component is fixed to the base, so that the connecting part can rotate at any angle. At the same time, a T-shaped groove communicating with the annular groove is opened on the outer side of the telescopic rod, and a limiting component is set in the T-shaped groove. The limiting component and the slot on the annular component are interlocked to fix the annular component, thereby maintaining the stability of the connecting part after rotation. When the telescopic rod of the electric cylinder is connected and fixed to the target, the installation angle can be adjusted, so that the telescopic rod and the target fit more tightly, avoiding damage caused by poor fit, and increasing practical performance.
[0016] 2. In this utility model, a sliding groove is opened on the outer side of the base, and a slider is fixed at the end of the connector. The slider and the sliding groove are interlocked. At the same time, a fixing member is provided that is interlocked with the sliding groove and fixed in the sliding groove by fixing bolts. When the electric cylinder is replaced, the fixing bolts are simply unscrewed and the fixing member is removed, and the connector can be slid out of the base to replace the connector with a connector of a different diameter. This increases the convenience of the electric cylinder connector during installation and disassembly, reduces the operation process, shortens the replacement time, and increases the practicality.

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0024] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0025] Some embodiments of the present invention are described below with reference to the accompanying drawings. Figure 1-3 A multi-stage dual-speed electric cylinder includes a main module 100 and an adapter module 200. The main module 100 includes an electric cylinder body 110 and a telescopic rod 120 with one end disposed in the inner cavity of the electric cylinder body 110 and the other end extending out of the electric cylinder body 110. The electric cylinder body 110 is used to drive the telescopic rod 120 to perform telescopic movement. The telescopic rod 120 is used to connect with a target, thereby driving the target to perform telescopic movement. At the same time, the telescopic rod 120 is used to install the adapter module 200. An annular groove 121 is opened on the end of the telescopic rod 120, and a T-shaped groove 122 is opened on the outer surface of the telescopic rod 120. The bottom end of the T-shaped groove 122 communicates with the annular groove 121 for the installation of the adapter module 200.
[0026] The adapter module 200 is used to facilitate the adjustment of the angle of the connector 242 and its quick replacement. It includes an annular component 210 fitted onto the main module 100, a base 220 fixed to the outer surface of the annular component 210, a limiting component 230 movably mounted on the main module 100 and extending into the main module 100, a fixing component 240 slidably mounted on the base 220, a fixing block 250 fitted onto the base 220, and a fixing bolt 260 extending through the fixing block 250 into the base 220. The annular component 210 is fitted into the annular groove 121, allowing the annular component 210 to rotate within the annular groove 121, meaning the base 220 can rotate at any angle. The limiting component 230 is installed in the T-slot 122, including components movably mounted in the T-slot. The T-shaped component 231 in the groove 122, the spring 232 connecting the bottom end of the T-shaped component 231 to the bottom wall of the groove 122, and the lifting rod 233 hinged to the top of the T-shaped component 231 are arranged in a ring array on the outer surface of the ring component 210. The T-shaped component 231 and the slot 211 are interlocked, so that the T-shaped component 231 can limit the ring component 210 and keep the ring component 210 stable at a fixed angle. The spring 232 is used to keep the T-shaped component 231 in a contracted state, so that the T-shaped component 231 is always interlocked in the slot 211. The lifting rod 233 is used to facilitate the operator to lift the T-shaped component 231, so that the T-shaped component 231 is disengaged from the slot 211 and loses its limiting effect on the ring component 210, which facilitates operation.
[0027] The base 220 is used to install the connector 242. A groove 221 is formed on the outer surface of the base 220 for fixing the assembly 240. The fixing assembly 240 includes a slider 241 that slides within the groove 221 and a connector 242 integrally fixed to the end of the slider 241. The slider 241 and the groove 221 engage with each other, ensuring the stability of the slider 241 and facilitating its sliding in and out, thus increasing convenience. The connector 242 has a round hole for a bolt to pass through for connection to the target. (Fixing block 250) The slide 241 is fitted into the groove 221 to limit the up and down movement of the slider 241 and maintain its stability. The inner wall of the groove 221 has a screw hole 222. The fixing bolt 260 passes through the fixing block 250 and engages in the screw hole 222, thereby fixing the fixing block 250 to the base 220 and maintaining the stability of the fixing block 250, that is, maintaining the stability of the slider 241 and the connecting piece 242. The end of the fixing bolt 260 has an internal hexagonal groove, which makes it convenient for workers to tighten the fixing bolt 260 with a hexagonal wrench, increasing convenience.
[0028] The working principle and usage process of this utility model are as follows: When in use, bring the connector 242 close to the target and check if the diameter of the connector 242's hole matches the target's hole diameter. If they do not match and replacement is required, rotate the fixing bolt 260 to disengage it from the screw hole 222, thus losing its fixing effect on the fastener. Remove the fastener, then slide the slider 241 and connector 242 out of the groove 221. Select an appropriate connector 242, slide the slider 241 into the groove 221, and then fit the fastener into the groove 221 and position it above the slider 241. Pass the fixing bolt 260 through the fastener. Engagement within the screw hole 222 secures the fastener, thereby fixing the connector 242. When there is an angular difference between the connector 242 and the target, the lifting rod 233 pulls the T-shaped rod outward, causing the T-shaped rod to disengage from the slot 211 and lose its restraint on the annular part 210. Rotating the base 220 adjusts the angle of the connector 242. When the angle of the connector 242 is parallel to the target angle, the lifting rod 233 is released. At this time, the lifting rod 233 retracts under the action of the spring 232 and engages within the slot 211, restraining the annular part 210 and maintaining its stability.
