Description

Technical Field

[0001] The utility model relates to the technical field of lathe protection, in particular to a protective device for a vertical lathe crossbeam lifting structure. Background Art

[0002] Vertical lathe is abbreviated as "vertical lathe". It is mainly used to process large and heavy workpieces with large diameter and short length, and workpieces that are not easy to clamp on horizontal lathes. When the rotation diameter is met, workpieces that are too heavy are not easy to clamp on horizontal lathes. Due to their own weight, the processing accuracy is affected. The use of vertical lathes can solve the above problems.

[0003] When machining a workpiece, the vertical lathe controls the height and horizontal position of the tool through the crossbeam, and in order for the tool holder to move normally, one side of the crossbeam is exposed;

[0004] First, in order to protect the internal moving components, the existing crossbeams will install protective components on the surface, but these protective components are all sleeved metal plates. Since the tool holder has a large movement range, multiple tool holders need to be installed to always cover the crossbeam. This requires a lot of time to remove the metal plates when inspecting the device, resulting in low loading and unloading efficiency and reduced practicality of the device.

[0005] Second, in order to protect the crossbeam of the lathe, a large number of retractable metal plates will be installed outside the crossbeam. However, due to the large number of metal plates installed, a certain production cost is required during the production of the lathe, thereby increasing the production cost of the device.

[0006] The utility model aims to provide a protective device for a vertical lathe crossbeam lifting structure to solve the problems raised in the above-mentioned background technology.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a protective device for a vertical lathe crossbeam lifting structure, comprising a lathe body; protective sleeves located on both sides of the lathe body, the protective sleeves are used to protect the crossbeam body; a connecting frame located on one side of the protective sleeve, the connecting frame is used to fix the protective sleeve; a crossbeam body is slidably connected to the lathe body, a side of the crossbeam body away from the lathe body is slidably connected to a tool holder, two sides of the tool holder are bolted to a fixing frame, a side of the fixing frame away from the tool holder is tightly attached to the connecting frame, a side of the connecting frame away from the tool holder body is bolted to the protective sleeve, an end of the protective sleeve away from the connecting frame is bolted to an edge sealing block, a plug plate is welded on a side of the connecting frame close to the tool holder, the plug plate is movably embedded in the fixing frame, a movable groove is opened on a side of the fixing frame away from the lathe body, a movable rod runs through the movable groove, and a limit block is provided on a side of the movable rod close to the crossbeam body.

[0008] Preferably, a baffle is closely attached to a side of the edge sealing block away from the protective sleeve, a fixing plate is welded to one side of the baffle, and a side of the fixing plate close to the lathe body is bolted to the outside of the lathe body.

[0009] Preferably, the connecting frame, the protective sleeve and the edge sealing block all cover the outside of the beam body, and a penetrating positioning groove is opened on the plug plate.

[0010] Preferably, a connecting slot is formed on a side of the movable groove close to the beam body, the plug plate is inserted into the slot, and a side of the limit block close to the movable rod is closely attached to a side of the plug plate away from the movable rod.

[0011] Preferably, a connecting rotation groove is formed on a side of the slot away from the movable groove, a connecting contraction groove is formed on the other side of the rotation groove, and an elastic member is bolted to the contraction groove on a side away from the rotation groove.

[0012] Preferably, a push plate is bolted to one end of the elastic member close to the rotation groove, and the push plate abuts against a side of the limit block away from the movable rod.

[0013] Preferably, the limit block is located in the rotation groove, an adjustment rod is movably penetrated through the movable rod, and one end of the adjustment rod close to the limit block is bolted to the surface of the limit block.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, rotate the adjustment rod ninety degrees to drive the limit block to rotate to a horizontal state with the positioning groove. At this time, pull the movable rod outward, and the movable rod will pull the limit block out along the positioning groove and the movable groove. At this time, the plug board can be taken out of the slot, and then the protective cover can be taken off. When the limit block is located in the rotating groove, the push plate will press the limit block tightly against the surface of the plug board through the elasticity of the elastic part itself. Multiple components cooperate with each other to realize the rapid loading and unloading of the protective cover, thereby improving the practicality of the device.

[0016] Second, when the tool holder moves horizontally on the beam body, it will pull the connecting frame, and then pull the protective cover on both sides. When the tool holder moves back and forth, the protective cover will fold or stretch according to its own creases and elasticity, but it will always cover the outside of the beam body. The rubber protective cover can reduce the production cost of the beam body protection device, thereby reducing the production cost of the device. BRIEF DESCRIPTION OF THE DRAWINGS

When the stop block 14 is located in the rotating groove 17, the push plate 20 will press the stop block 14 tightly against the surface of the plug plate 10 through the elasticity of the elastic member 19 itself. Multiple components cooperate with each other to realize the rapid assembly and disassembly of the protective cover 5, thereby improving the practicality of the device.

[0025] Specifically, a baffle plate 7 is closely attached to a side of the edge sealing block 6 away from the protective sleeve 5 , a fixing plate 8 is welded to one side of the baffle plate 7 , and a side of the fixing plate 8 close to the lathe body 1 is bolted to the outside of the lathe body 1 .

[0026] Through the above technical solution, when the edge sealing block 6 contacts the baffle plate 7, the protective sleeve 5 will be blocked from moving further.
