Description

Technical Field

[0001] The utility model belongs to the technical field of dial disassembly and assembly, in particular to a grinding machine headstock dial disassembly and assembly tool. Background Art

[0002] Grinders are commonly used for precision machining, particularly in the heavy equipment processing and manufacturing industries. Disassembly and assembly of the grinder headstock dial is a crucial maintenance task. Traditionally, disassembly and assembly of grinder headstock dials requires the collaboration of multiple operators, often using tools such as crowbars and copper rods. This traditional method is not only inefficient but also poses significant safety risks.

[0003] First, traditional disassembly and assembly methods often require the coordinated efforts of three to four workers. Because dials are often large and heavy, the tooling can easily wobble or shift during disassembly and installation, leading to operational errors. Furthermore, rough manual manipulation, such as using a crowbar or striking with a copper rod, can easily damage the dial and related components, increasing the equipment's failure rate. Especially during striking and prying, uneven force distribution can cause the dial to become stuck, further increasing the difficulty and time required for repairs.

[0004] Secondly, safety is another major issue with traditional operation methods. Without a safe and reliable lifting point, operators often need to manually push or remove the dial during the disassembly process, which greatly increases the risk of accidents such as crushing and falling injuries.

[0005] At the same time, when using lifting equipment, due to the lack of dedicated lifting tools, lifting injuries are very likely to occur. This non-standard operation method brings huge safety hazards to workers and affects the safety and efficiency of operations. Utility Model Content

[0006] The present utility model aims to address the problems existing in the prior art by providing a tool for disassembling and assembling the dial of a grinding machine headstock. Through its rational design, the tool significantly simplifies the assembly and disassembly process of the dial. The synergistic action of the nut and screw allows for effective ejection of the dial. This tool not only evenly distributes force on the dial, preventing it from getting stuck due to uneven force during assembly and disassembly, but also eliminates the potential damage and safety risks associated with traditional tools such as crowbars and copper rods by using a screw to rotate and eject the dial.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a grinding machine headstock dial disassembly and assembly tool, including a hanging frame and a screw, a first mounting groove is provided on both sides of the hanging frame, a nut is provided in the first mounting groove, a screw connected to the dial is installed in the nut, a nut is provided on one side of the screw, the nut is installed in the groove of the dial, and the screw is installed in the screw hole of the first mounting groove and pushes the dial out.

[0008] Preferably, four nuts are provided, and the first mounting groove on each side is provided with two symmetrically distributed nuts.

[0009] Preferably, four screw rods are provided, and the first mounting groove on each side is provided with two symmetrically distributed screw rods.

[0010] Preferably, the upper screw is located above the upper nut and does not contact the dial.

[0011] Preferably, the screw rod on the lower side is located at the lower part of the nut on the lower side and does not contact the dial.

[0012] Preferably, a second mounting slot is provided on the upper portion of the hanging bracket, and a lifting lug is provided on the upper portion of the second mounting slot.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The fixture effectively ejects the dial. It not only evenly distributes force on the dial, preventing it from getting stuck during assembly and disassembly due to uneven force, but also eliminates the potential damage and safety risks associated with traditional tools like crowbars and copper rods by using a screw to rotate and eject the dial.

[0015] In addition, the screw rod ensures a firm connection between the tooling and the dial, preventing the tooling from sliding or shifting during operation, further improving the safety of the operation.

[0016] The second mounting slot and lifting eye on the upper part provide additional lifting functions for the tooling, enabling the tooling to be used flexibly in complex vertical or suspended operating environments.

[0017] After using this fixture, a task that once required three to four workers can now be completed by just two. The fixture's rigid structure and stability ensure safe and efficient operation. Furthermore, the fixture has reduced the time required for grinding headstock maintenance from 48 hours to just eight, significantly improving work efficiency and reducing equipment downtime, resulting in significant economic benefits and safety improvements.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] refer to Figure 1-2 As shown, the utility model discloses a tool for disassembling and assembling the dial of the grinding machine head frame, including a hanging frame 1 and a screw 5. A first mounting groove 2 is provided on both sides of the hanging frame 1, a nut 3 is provided in the first mounting groove 2, a screw 4 connected to the dial is installed in the nut 3, a nut is provided in the screw 4, the nut is installed in the groove of the dial, and the screw 5 is installed in the screw hole of the first mounting groove 2 and pushes the dial out; the hanging frame 1 ensures that the tool will not be deformed or shaken during the disassembly and assembly of the dial by providing rigidity and stability. In addition, the hanging frame 1 also provides a basis for the installation and positioning of other functional components. When in use, the hanging frame 1 is first installed to the appropriate position, and then the nut of the screw 4 is connected to the groove on the dial, and the screw 5 is rotated to push the dial out. At the same time, the nut 3 provides a fixed point for the screw 4. Due to the rotation of the screw 5, it moves axially relative to the hanging frame 1, thereby pushing the dial 4 outward.

[0023] There are four nuts 3, and two symmetrically distributed nuts 3 are provided on each side of the first mounting groove 2. The four nuts 3 are distributed on both sides of the first mounting groove 2 to form a uniform ejection force, so that the dial can be fixed smoothly and steadily.

[0024] The screw rods 5 are used to push out the dial and displace it. The four screw rods 5 push out the upper and lower parts of the dial, ensuring that the tooling does not slip or shift during operation. At the same time, symmetrical first mounting slots 2 are provided on both sides of the hanging frame 1 to ensure the proper distribution of the screw rods 4 and connecting screw rods 5. This ensures that the dial is evenly stressed during removal, preventing the dial from getting stuck or damaged due to uneven force.

[0025] Four screw rods 5 are provided, with two symmetrically distributed screw rods 5 provided in each first mounting slot 2. The upper screw rod 5 is located above the upper nut 3 and does not contact the dial, while the lower screw rod 5 is located below the lower nut 3 and does not contact the dial. Rotating the screw rods can generate a driving force through their threaded structure and interaction with the hanging bracket 1, thereby ejecting the dial.

[0026] The upper portion of the lifting frame 1 is provided with a second mounting slot 6, and a lifting lug 7 is provided above the second mounting slot 6. The second mounting slot 6 and the lifting lug 7 provide additional fixing and lifting functions. Especially when the tooling needs to be moved or suspended, the lifting lug 7, installed on the top of the lifting frame 1, enables stable lifting of the tooling. This design allows the tooling to be operated not only on the ground but also in applications requiring suspension or vertical space.

[0027] In summary, the present application enables the work that originally required 3-4 people to work together to be completed by 2 people by using the grinding machine headstock dial disassembly and assembly tooling.

[0028] Before the fixture was installed, maintenance and inspection of the grinding machine headstock took a long time, averaging around 48 hours. After the fixture was installed, this time was reduced to around 8 hours, improving operational efficiency.

[0029] Before the tooling is used, there is no safe and reliable lifting point, and lifting injuries are very likely to occur. After the tooling is used, the safety of the lifting operation is improved and the very likely lifting injuries are eliminated!

[0030] Before using the tooling, use a crowbar to prevent tilting or a copper rod to knock it apart, which may cause safety hazards such as squeezing and hitting. After using the tooling, a screw rod is used to push it out, which improves the safety of the operation and eliminates the safety hazards caused by knocking with a sledgehammer or a copper rod.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
