DETAILED DESCRIPTION

[0021] like Figure 1-3 As shown, the present invention proposes a positioning device for rotor body processing, which cooperates with the rotor body 5; both ends of the rotor body 5 are provided with connecting rods 501, and a plurality of grooves 502 are provided on the side wall. The positioning device for rotor body processing comprises a base 1, a clamping assembly 3, a driving assembly 2 and a positioning assembly 4. The clamping assembly 3 is arranged on the base 1 to clamp the connecting rods 501 at both ends of the rotor body 5. The driving assembly 2 is arranged on the base 1 to drive the clamping assembly 3 to rotate so as to drive the rotor body 5 to rotate. The positioning assembly 4 is arranged on the base 1, and cooperates with the grooves 502 provided on the rotor body 5 to prevent the rotor body 5 from further rotating.

[0022] Further explanation, the driving assembly 2 includes a fixing seat 1 21 symmetrically arranged on the base 1; a rotating shaft 22 is rotatably connected between the two fixing seats 1 21; one end of the rotating shaft 22 is connected to a driving mechanism 1 23, and a gear 1 24 is symmetrically arranged on the side wall; one end of the two gears 1 24 is respectively meshed and connected to a gear 2 25, and the two gears 25 are coaxial; the two gears 25 are respectively rotatably connected to the fixing seat 2 26 arranged on the base 1. The two clamping assemblies 3 can be driven to rotate synchronously, thereby driving the rotor body 5 to rotate stably, facilitating the processing of different surfaces of the rotor, and preventing the rotor body 5 from slipping during processing, thereby improving the processing quality.

[0023] Further explanation: the clamping assembly 3 is respectively arranged at the opposite end of the two gears 25; the clamping assembly 3 includes a fixing seat 31 symmetrically arranged at the side wall of the gear 25; a bidirectional screw 32 is rotatably connected between the two fixing seats 31; one end of the bidirectional screw 32 is connected to a driving mechanism 2 33, on which a slide 34 is symmetrically threaded; the opposite ends of the two slides 34 are respectively connected to a clamping plate 35, and the two slides 34 are also respectively connected to a slide bar 36; the two slide bars 36 are both slidably connected to a slide groove 37 provided at the side wall of the gear 2 25. By clamping the connecting rod 501, the rotor body 5 is clamped, so that the rotor body 5 remains stable during the processing and does not shake back and forth to affect the processing. At the same time, the position of the rotor body 5 can be kept constant, so that the rotor body 5 corresponds accurately to the processing tool, etc., thereby improving the processing accuracy.

[0024] To further explain, the clamping plate 35 is an arc-shaped plate, so that the clamping plate 35 and the connecting rod 501 are more compatible, thereby reducing the probability of slipping.

[0025] Further explanation, two groups of positioning components 4 are symmetrically arranged on the base 1, and the positioning components 4 are arranged in an inclined manner, so that the positioning components 4 can position the rotor body 5 more stably.

[0026] Further explanation, the positioning assembly 4 includes a fixed frame 41 arranged on the base 1; the upper end of the fixed frame 41 is open, and a sliding plate 42 is slidably connected to the opening; a spring 43 is connected between one end of the sliding plate 42 and the fixed frame 41, and the other end is engaged with the groove 502, and an adjustment arc surface is provided; both sides of the adjustment arc surface are provided with limit plates 44 that abut against the side walls of the rotor body 5. When the rotor body 5 is processed and the rotor body 5 needs to remain stable, the spring 43 will push the sliding plate 42 to be inserted into the groove 502, limit the rotor body 5, and prevent the rotor body 5 from slipping and affecting the processing quality. The setting of the limit plate 44 can prevent the sliding plate 42 from penetrating into the groove 502, and cooperate with the adjustment arc surface to make the sliding plate 42 be pushed back into the fixed frame 41 when the rotor body 5 rotates.

[0027] The working principle of the utility model is as follows: when working, the rotor body 5 is first placed between the two gears 25, so that the connecting rod 501 is located between the two clamping plates 35. Then the driving mechanism 2 33 is started to drive the bidirectional screw 32 to rotate, thereby driving the two slide plates 34 and the clamping plates 35 to move relative to each other, so that the clamping plates 35 clamp the connecting rod 501. When the rotor body 5 needs to be rotated, the driving mechanism 1 23 is started to drive the rotating shaft 22 and the gear 1 24 to rotate, thereby driving the gear 2 25 and the clamping assembly 3 to rotate, and then driving the rotor body 5 to rotate. After the rotation is completed, the spring 43 will push the sliding plate 42 to engage in the corresponding groove 502, position the rotor body 5, and prevent the rotor body 5 from slipping and affecting the processing quality.

[0028] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
