Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, in particular to a special clamp for casing processing. Background Art

[0002] The three-phase asynchronous motor is a type of induction motor. It is a type of motor that is powered by a 380V three-phase alternating current. Since the rotor and stator rotating magnetic field of the three-phase asynchronous motor rotate in the same direction and at different speeds, there is a slip rate, so it is called a three-phase asynchronous motor. The speed of the rotor of the three-phase asynchronous motor is lower than the speed of the rotating magnetic field. The rotor winding generates electromotive force and current due to the relative motion between the rotor and the magnetic field, and interacts with the magnetic field to generate electromagnetic torque to achieve energy conversion. When the casing of the three-phase asynchronous motor is inspected and repaired, it needs to be positioned and fixed using a special fixture.

[0003] In a positioning fixture for processing a motor housing in a Chinese patent (patent number: CN220481448U), the device includes a support frame, one side of the support frame is rotatably connected with a rotating mechanism, one side of the rotating mechanism is fixedly connected with a first mounting plate through multiple groups of support columns, one side of the first mounting plate is fixedly installed with a clamping mechanism for clamping the housing, and one side of the first mounting plate and located above the clamping mechanism is fixedly installed with a placement mechanism. The device can clamp and position the housing to be detected by setting the clamping mechanism, and when the housing is placed, it can first contact the placement mechanism, and then the clamping mechanism can be used for clamping and positioning, so that the clamping mechanism can be conveniently positioned. Subsequently, when observing and inspecting, the setting of the rotating mechanism can enable the user to observe the housing in all directions, and the positioning structure set can position the rotating mechanism when it is not rotated for observation. However, the device can only position one end of the housing of the three-phase asynchronous motor, the fixation is not reliable enough, and the rotation positioning adjustment operation of the housing is not convenient enough, and it is inconvenient to use.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] See also Figures 1 to 4 In the practical embodiment, a special fixture for processing a casing is provided. The casing refers to the casing of a three-phase asynchronous motor, which is generally cylindrical and includes a base bar shell 1. A spacing adjustment mechanism is provided in the base bar shell 1. Two upper ends of the spacing adjustment mechanism are fixedly connected to two symmetrically arranged clamping mechanisms, which can provide more stable and reliable positioning support for the casing. A lifting mechanism is fixedly connected to the upper side wall of the base bar shell 1, and a control switch 2 is fixedly connected to the front side wall of the base bar shell 1.

[0025] Specifically, the clamping mechanism includes a fixed shell 3 fixed to the upper end of the spacing adjustment mechanism, one end of the fixed shell 3 is fixedly connected to the first telescopic cylinder 4, one end of the fixed shell 3 away from the first telescopic cylinder 4 is inserted and rotatably connected to a round cover shell 5, one end of the first telescopic cylinder 4 is rotatably connected to a rotating block 6 through a rotating member, one side of the rotating block 6 is hingedly connected to two rocker rods 7, the inner wall of the round cover shell 5 is fixedly connected to a support rod 8, a sliding sleeve 9 is sleeved on the support rod 8 and slidably connected, the two sliding sleeves 9 are respectively hingedly connected to one end of the two rocker rods 7, one end of the two sliding sleeves 9 are fixedly connected to a connecting block 10, a sliding opening 11 is opened on one side of the round cover shell 5, one end of the two connecting blocks 10 Both pass through the sliding opening 11 and are fixedly connected with two symmetrically arranged arc-shaped abutment plates 12. A rotating mechanism is provided on the fixed shell 3, and one end of the rotating mechanism is fixedly connected to the round cover shell 5. When the casing needs to be clamped and fixed, the two arc-shaped abutment plates 12 are inserted into the interior of the casing, and the first telescopic cylinder 4 is started to work and extend to push the rotating block 6 to move. At this time, the two rocker arms 7 swing, thereby pushing the two sliding sleeves 9 to move in opposite directions on the support rod 8, thereby pushing the arc-shaped abutment plates 12 fixed to the connecting block 10 to move, until the two arc-shaped abutment plates 12 are pressed against the inner walls on both sides of the casing, thereby realizing the tight positioning of the casing, which is firmly fixed and easy to operate.

[0026] like Figure 2 and Figure 3As shown: the rotating mechanism includes a first motor 13 fixed on one side of the fixed shell 3, and the two first motors 13 work synchronously to keep the rotation speed consistent. The main shaft end of the first motor 13 passes through the fixed shell 3 and is fixedly connected to a worm 14. The outer wall of the circular cover shell 5 is fixedly connected to a worm wheel ring 15 meshing with the worm 14. Starting the first motor 13 can drive the worm 14 to rotate. Since the worm 14 is meshing with the worm wheel ring 15, the circular cover shell 5 can be driven to rotate, and then the casing pressed against the two arc-shaped abutment plates 12 can be driven to rotate. The rotation adjustment is convenient, the positioning is accurate and stable, and it is convenient to process the casing.

[0027] like Figure 3 As shown, the outer wall of the circular cover shell 5 and the inner wall of the through hole of the worm wheel ring 15 are fixedly connected by welding, and the connection is firm.

[0028] like Figure 4 As shown: the spacing adjustment mechanism includes a second motor 16 fixed to one end of the base strip shell 1, the main shaft end of the second motor 16 passes through the base strip shell 1 and is fixedly connected to a bidirectional screw rod 17, and two symmetrically arranged nut blocks 18 are threadedly connected to the bidirectional screw rod 17. The upper ends of the two nut blocks 18 are fixedly connected to a moving frame 19, and the upper side wall of the base strip shell 1 is provided with two openings 20. The upper ends of the two moving frames 19 pass through the two openings 20 respectively and are fixedly connected to the two fixed shells 3 respectively. The second motor 16 is started to work, driving the bidirectional screw rod 17 to rotate. Since the bidirectional screw rod 17 is threadedly connected to the two nut blocks 18 respectively, at this time, the two nut blocks 18 are forced to move in opposite directions, thereby driving the two clamping mechanisms fixed to the two moving frames 19 to move in opposite directions to achieve spacing adjustment.

[0031] like Figure 1 As shown: the four corners at both ends of the base strip shell 1 are fixedly connected with support floors 23 to provide stable support.

[0032] The working principle of the utility model is as follows: when the device is used to position and clamp the casing of the three-phase asynchronous motor, the casing is placed on 22, 21 is started to work and extend, and the casing on 22 is lifted to the height corresponding to 12, and then the second motor 16 is started to work, driving the bidirectional screw rod 17 to rotate. Since the bidirectional screw rod 17 is threadedly connected with the two nut blocks 18 respectively, at this time, the two nut blocks 18 are forced to move in opposite directions, thereby driving the two clamping mechanisms fixed with the two moving frames 19 to move in opposite directions and insert into the two ends of the casing, and then, the first telescopic cylinder 4 is started to work and extend, pushing the rotating block 6 to move, at this time, the two swing rods 7 swing, thereby pushing the two sliding sleeves 9 to move in opposite directions on the support rod 8, and then pushing the arc-shaped abutment plate 12 fixed with the connecting block 10 to move, until the two arc-shaped abutment plates 12 are tightly pressed against the inner walls of the two sides of the casing, thereby realizing the tight positioning of the casing, firm fixation, and convenient operation, and then, 21 is started to work and retract, driving 22 to move down and separate from the casing.

[0033] Secondly, when the casing needs to be rotated and adjusted during the processing, the two 13 are started to work synchronously, which can drive the worm 14 to rotate. Since the worm 14 is engaged with the worm wheel ring 15, the circular cover shell 5 can be driven to rotate, and then the casing pressed against the two arc-shaped abutment plates 12 can be driven to rotate. The rotation adjustment is convenient, the positioning is accurate and stable, and it is convenient to process the casing.
