Description

Technical Field

[0001] The utility model relates to the technical field of screw disassembly and assembly, and particularly relates to a screw clamping device for screw machine disassembly and assembly. Background Technique

[0002] In the field of industrial production, as an important mechanical equipment, screw machines are widely used in the process links such as material conveying, mixing, and plasticizing. Among them, the double-screw structure plays a key role in many industries due to its unique working characteristics. However, after long-term use, the double screw inevitably needs to be repaired, maintained, or its parts replaced, etc.

[0003] Currently, when disassembling and assembling small double screws, a relatively traditional and simple method is generally adopted. Workers usually place two wooden board pads on the operation table and place the double screw on the pads as a preliminary support. However, this method has some defects: when disassembling the threaded elements on one screw shaft core, the other screw, relying only on simple wooden board pads for support and lacking effective limiting means, is extremely prone to rolling. This will not only interfere with the ongoing disassembly operation but also lead to low disassembly efficiency.

[0004] Therefore, in view of the above situation, a screw clamping device for screw machine disassembly and assembly is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a screw clamping device for screw machine disassembly and assembly. By fixing the bottom plate on the table and opening an arc groove in the support seat, the arc groove can fit the outer contour of the screw to provide clamping restraint for the screw, effectively avoiding the rolling phenomenon of the screw, and solving the problem that the existing device lacks effective limiting means and is extremely prone to rolling, which will interfere with the ongoing disassembly operation.

[0006] The utility model is realized through the following technical solutions:

[0007] The utility model is a screw clamping device for screw machine disassembly and assembly, including a bottom plate and a placement plate. At both ends of the top of the bottom plate, support seats are respectively fixed. Arc grooves for limiting the screw are respectively opened on the two support seats. There are two placement plates, and both ends of the two placement plates are respectively fixed on the support seats. A row of placement grooves for placing threaded elements are opened on the placement plate.

[0008] Furthermore, the shape of the support seat is "I"-shaped, and the number of arc grooves on each support seat is two.

[0009] Furthermore, a rubber pad fitting the surface of the arc groove is arranged on the arc groove, and anti-slip lines are opened on the rubber pad.

[0010] Furthermore, the bottom of the placement plate has a through hole that connects to the placement groove, and an ejector rod is fitted into the through hole with clearance. The insertion end of the ejector rod is connected to an ejector plate, and the ejector plate is fitted into the placement groove with clearance.

[0011] Furthermore, the insertion end of the ejector rod has a threaded portion, and the bottom of the ejector plate has a threaded hole, with the threaded portion and the threaded hole engaging in a threaded fit.

[0012] This utility model has the following beneficial effects:

[0013] This invention fixes the base plate to the table and creates an arc-shaped groove in the support base. The arc-shaped groove conforms to the outer contour of the screw, providing clamping constraint for the screw. When disassembling the threaded components on one screw shaft, the other screw is securely confined within the arc-shaped groove, effectively preventing the screw from rolling. This ensures that the disassembly operation can be carried out smoothly in a stable environment, greatly improving disassembly efficiency and eliminating potential safety hazards caused by accidental screw rolling.

[0014] This utility model, through the structural design of the placement plate and placement slot, provides an orderly storage space for disassembled threaded components during use. Compared with the existing technology where threaded components are placed directly on the table, it can avoid accidental collisions that could lead to the threaded components being confused, thus facilitating subsequent assembly work, shortening the time cost required to find and identify components, and reducing the risk of incorrect installation due to component confusion.

[0015] This utility model, through the structural design of through hole, ejector rod and ejector plate, can facilitate the removal of threaded components when they are small in size and difficult to remove after being placed in the placement slot, by operating the ejector rod, thus reducing the difficulty for workers to handle them.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. 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] Please see Figure 1-4 This utility model provides a technical solution: a screw clamping device for disassembling and assembling a screw compressor, including a base plate 1 and a placement plate 3. The top two ends of the base plate 1 are respectively fixed with "I"-shaped support seats 2 by bolts. The two support seats 2 are respectively provided with arc-shaped grooves 201 for limiting the screw. Each support seat 2 has two arc-shaped grooves 201. Rubber pads 202 that fit against the surface of the arc-shaped grooves 201 are provided on the arc-shaped grooves 201. Anti-slip textures are provided on the rubber pads 202. The two ends of the screw are respectively clamped in the arc-shaped grooves 201. Through the elastic properties of the rubber pads 202, the two ends of the screw can be clamped and limited, preventing the screw from sliding after placement.

[0024] There are two placement plates 3, and the two ends of the two placement plates 3 are fixed on the support base 2 respectively. A row of placement slots 301 for placing threaded components is opened on the placement plate 3. The side of the placement plate 3 can be marked with the numerical labels corresponding to the placement slots 301, so as to further help the staff distinguish the disassembly and assembly sequence of the threaded components during disassembly and assembly operations and reduce the occurrence of confusion during disassembly and assembly.

[0025] As a further description of the above embodiment, the bottom of the placement plate 3 is provided with a through hole 302 that communicates with the placement groove 301. An ejector rod 303 is fitted with the through hole 302 with clearance. The insertion end of the ejector rod 303 is connected to an ejector plate 304. The ejector plate 304 is fitted with the placement groove 301 with clearance. When the threaded element is placed in the placement groove 301 and is inconvenient to remove, the worker can lift the ejector rod 303 upwards, which will cause the ejector rod 303 to move upwards and drive the ejector plate 304 to move upwards, thereby ejecting the threaded element located in the placement groove 301, so that the worker can quickly pick it up.

[0026] The ejector rod 303 has a threaded end, and the bottom of the ejector plate 304 has a threaded hole. The threaded part is threadedly engaged with the threaded hole. The threaded part is an external thread structure formed on the ejector rod 303 by machining. The ejector rod 303 and the ejector plate 304 are detachably connected to facilitate their assembly.

[0027] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
