Description

Technical Field

[0001] The utility model relates to the technical field of parts heat treatment, in particular to a top for heat treatment equipment. Background Art

[0002] In the process of heat treatment of parts, a center is usually needed. Generally, an upper center is used to drive the part to rotate. The upper center is installed on the inner sleeve of the rotating cylinder on the machine tool, and the upper center is driven to rotate as a whole by the rotating cylinder. Due to the large mass of the center itself, the inner sleeve of the cylinder will be worn out after long-term use, and as time changes, the part will cause large vibrations, which will affect the product quality. Therefore, the center needs to be tracked and replaced regularly, which is not suitable for use in large-scale production lines. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the present application provides a top tip for heat treatment equipment, including a top tip rod and a top tip head. The top tip head and the top tip rod are matched with a Morse taper to achieve a rotational connection between the top tip and the top tip rod. A disassembly assembly is provided at the connection between the top tip and the top tip rod for removing the top tip from the top tip rod.

[0004] Furthermore, the top rod is a cylindrical structure, including a main body and a mounting portion, a sliding cavity is provided in the mounting portion along its axial direction, and the top head is arranged in the sliding cavity.

[0005] Furthermore, the tip head includes a cone portion and a tip portion, the cone portion and the sliding cavity form a Morse taper fit, and a gap is formed between the tip portion and the mounting portion.

[0006] Furthermore, the disassembly assembly includes a locking nut and a disassembly plate, the locking nut is threadedly connected to the mounting portion, and the disassembly plate can be movably inserted into the gap.

[0007] Furthermore, the mounting portion is provided with an external thread inwardly along its end portion, and the disassembly plate is a U-shaped plate so that it can be inserted into the gap.

[0008] Further, the plane where the disassembly plate is located is defined as a projection plane, and in a direction perpendicular to the projection plane, the projection interval of the locking nut falls within the projection plane of the disassembly plate.

[0009] Furthermore, a limit block is provided at the free end of the main body, and the limit block is fixedly connected to the main body by bolts.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] See also Figure 1-5 The present embodiment provides a top tip for heat treatment equipment, including a top tip rod 10 and a top tip head 11 arranged at the bottom of the top tip rod. The top tip head 11 and the top tip rod 10 are matched with each other using a Morse taper to realize a rotational connection between the top tip head and the top tip rod. A disassembly assembly is provided at the connection between the top tip head and the top tip rod for removing the top tip from the top tip rod.

[0024] Specifically, the top rod 10 is a cylindrical structure as a whole, including a main body 101 and a mounting portion 102. The diameter of the mounting portion 102 is larger than the diameter of the main body 101. A sliding cavity 103 is opened in the mounting portion 102 along its axial direction, and the top head 11 is arranged in the sliding cavity 103.

[0025] More specifically, the tip head 11 includes a cone portion 111 and a tip portion 112. The cone portion 111 and the sliding cavity 103 form a Morse taper, so the shape and size of the sliding cavity must be compatible with the shape and size of the cone portion 111. A disassembly gap 16 is formed between the top of the tip portion 112 and the bottom of the mounting portion 102.

[0026] The disassembly assembly includes a locking nut 13 and a disassembly plate 12. The mounting portion 102 is provided with an external thread (not shown in the figure) upwardly along its bottom end. The locking nut 13 is sleeved on the external thread. The disassembly plate 12 is a rectangular plate and a U-shaped groove 121 is provided along one side thereof so that it can be inserted into the disassembly gap 16.

[0027] Since the top head needs to be removed by the lock nut 13 and the disassembly plate 12, the length or width of the disassembly plate 12 is greater than the outer diameter of the lock nut 13. A limit block 14 is provided at the free end of the main body 101, and a threaded hole is provided inwardly at the free end of the main body 101. The limit block 14 is connected to the threaded hole through a ball bolt 15, wherein the limit block 14 is also a cylindrical structure, and its diameter is greater than the diameter of the mounting portion 102, and a through hole is provided inside the limit block 14 for the ball bolt to pass through.

[0028] Working principle: During installation, first put the top rod 10 into the rotating cylinder sleeve of the machine tool. Since there are no parts under the top at this time, the top is easy to slip, so the limit block 14 is fixed to the top rod through the ball bolt 15, so that when the top slides down, the limit block 14 abuts against the cylinder sleeve to prevent slipping, and then insert the top head 11 into the sliding cavity 103 of the top rod. During use, only the top head 11 rotates, and the top rod 10 does not rotate. When the top head needs to be disassembled, screw the locking nut onto the mounting part, insert the disassembly plate 14 into the disassembly gap 16, and then screw out the locking nut 13, thereby driving the disassembly plate to bring the top head out.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
