Description

Technical Field

[0001] This utility model relates to processing equipment for workpieces such as shafts and discs, specifically a turntable structure with rotation and revolution functions. Background Technology

[0002] Shafts and discs are key components in mechanical equipment. In the heat treatment of these workpieces, high rotational speeds are required to ensure more uniform layer depth and a more stable metallographic structure. The processing cycle time is often a critical factor determining output, and a rotary table structure effectively improves this, increasing production capacity. Depending on customer needs, rotary tables can have 4, 6, or 8 stations, each with different functions. For example, a 6-station table might include loading / unloading, material height detection, heating, tempering (station 1 and station 2), and auxiliary cooling. This necessitates a rotating rotary table to allow the workpiece to complete six functions sequentially from loading. The heating and tempering stations also require rotation to ensure more uniform layer depth and a more stable metallographic structure during heat treatment. Currently, there is no such processing equipment. Therefore, inventing a rotary table structure with both rotation and revolution functions would be highly beneficial to meet these requirements. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing workpiece processing equipment by providing a turntable structure with both rotation and revolution functions. This structure can facilitate heat treatment processing of shaft and disc workpieces, thereby improving work efficiency.

[0007] The rotary worktable (2) is fixed with a rotary detection bracket (A9), the rotary detection bracket (A9) is fixed with a rotary detection switch (A10), and the rotary detection block (A11) is installed on the turntable (4).

[0008] A better technical solution of this utility model is as follows: the lower center component (5) includes a seat (C7), a (C1) that meshes with the male connector (B11) in the lifting component (6), and a rotating shaft (C4) that is hexagonally fitted with the female connector (C1). A spring (C3) is fitted on the rotating shaft (C4). A washer (C2) is provided between the female connector (C1) and the rotating shaft (C4). A round nut (C5) and a stop washer (C6) are sequentially provided on the upper part of the spring (C3). The body (C7) contains a deep groove ball bearing (B16) and a thrust ball bearing (C11). The bottom of the deep groove ball bearing (B16) is provided with a hole clip (C8). The seat body (C7) is fixed with a seat body O-ring seal (C10). The thrust ball bearing (C11) is provided with a rotating seal ring (C12). The top of the rotating shaft (C4) is equipped with a lower center sleeve (C14) and a limiting waterproof cover (C13).

An external hexagonal screw (D9) is fixed on one side of the tensioning fixing plate (D1), and an internal hexagonal nut (D10) is fixed on the other side of the external hexagonal screw (D9).

[0010] The working principle of this utility model is as follows: The rotary assembly is mounted on the turntable (4), and the turntable (4) is fixed on the divider (3). Driven by the divider (3), the turntable (4) rotates one division. After the turntable (4) completes one division, the rotary detection switch (A10) mounted on the detection bracket (A9) detects the rotary detection block (A11) mounted on the turntable (4) and transmits the action signal of completing one division, realizing the revolution of the turntable.

[0011] After the slewing assembly completes one indexing, the cylinder (B3) extends the lifting rod (B10) and the male connector (B11) under the action of air. The male connector (B11) engages with the female connector (C1) in the lower center assembly. After the lifting detection switch (B14) detects the detection block (B13), it transmits the position signal of the cylinder (B3). At this time, the geared motor (B19) receives the command and starts to move, driving the male connector (B11) to rotate. The male connector (B11) drives the female connector in the lower center assembly to rotate, thereby realizing the rotation of the workstation. After the workpiece is heated, the cylinder (B3) retracts the lifting rod (B10) and the male connector (B11) under the action of air. The male connector (B11) disengages from the female connector (C1) in the lower center assembly. After the lower detection switch (B14) detects the detection block (B13), it transmits the position signal of the cylinder (B3). The turntable (A8) starts to revolve under the drive of the divider (A3). In the lifting assembly, the male connector (B11) extends under the action of the cylinder (B3) and engages with the female connector (C1). Driven by the geared motor (B19), the female connector (C1) drives the rotating shaft (C4) and the clamp (C15) to rotate, thus achieving self-rotation.

[0012] If the chain (B21) is too long or stretched during installation or use, it will cause transmission to be jerky and inflexible. First, loosen the screw in the U-shaped groove on the tension adjustment plate (D2), and then turn the external hex screw (D9) to make the tension sprocket (D5) and the chain (B21) mesh tightly, eliminating the problem of the chain (B21) being too long and making the transmission smooth.

[0013] This utility model has the advantages of robust structure and long service life. It can conveniently perform heat treatment processing on shaft and disc workpieces, thereby improving work efficiency. Attached Figure Description
