Description

Technical Field

[0001] The utility model relates to the technical field of disassembly equipment, in particular to a motor disassembly device for a twisting machine. Background Art

[0002] A twisting machine is a device that twists fibers into yarns. It is generally composed of a motor, a twisting disk, and a bearing. The bearing is connected to the motor shaft, and the twisting disk is rotatably connected to the motor shaft. The motor needs to be regularly disassembled for maintenance during use. Since the motor of the twisting machine is installed in a small space, it is not convenient to use large equipment to disassemble and remove it. Currently, the motor is extracted by manually applying force to both sides of the twisting disk. During the lifting process, the motor and the twisting disk are prone to shaking due to uneven force on both sides, and the twisting disk is easily deformed, which affects the subsequent twisting quality, making the motor difficult to disassemble and inconvenient to disassemble.

At the same time, since the two supporting jaws are slidably connected to the cross bar, the two supporting jaws move close to each other to abut the bottom of the bearing. The supporting jaws support and drive the bearing to rise, so that the motor rises together with the bearing, thereby completing the lifting and disassembly of the motor. The positioning sleeve assists the position adjustment of the two supporting jaws to improve the clamping position accuracy of the two supporting jaws, so that the forces on both sides of the bearing are balanced, and the shaking of the motor and the twisting disk is reduced, thereby improving the stability of the motor disassembly. The positioning and lifting and disassembly processes are controlled by the screw above the motor, which is easy to operate and suitable for motor disassembly in a small space.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] It is understandable that, referring to Figures 1 to 6The utility model discloses a motor disassembly device for a twisting machine, comprising a bracket 100, a screw rod 200, a cross bar 300 and two supporting jaws 400. The screw rod 200 is threadedly connected to the bracket 100, and the screw rod 200 is arranged in the vertical direction; the cross bar 300 is slidably connected to the bracket 100, and the cross bar 300 is arranged in the horizontal direction. The cross bar 300 is rotatably connected to one end of the screw rod 200, and the screw rod 200 can drive the cross bar 300 to move up and down. A positioning sleeve 310 is fixedly connected to the bottom of the cross bar 300, and the positioning sleeve 310 can be sleeved on the outside of the bearing 800 to locate the position of the positioning sleeve 310; the two supporting jaws 400 are slidably connected to the cross bar 300, and the two supporting jaws 400 are symmetrically distributed on the opposite sides of the positioning sleeve 310, and the two supporting jaws 400 can move close to each other to abut the bottom of the bearing 800.

[0030] When in use, the bracket 100 is placed on the platform so that the positioning sleeve 310 is located above the bearing 800, and then the screw rod 200 is rotated to make the screw rod 200 drive the cross bar 300 to descend, and drive the positioning sleeve 310 to descend, so that the positioning sleeve 310 is sleeved on the outside of the bearing 800, and the position of the positioning sleeve 310 is adjusted by the reaction force of the bearing 800 on the positioning sleeve 310. The bracket 100, the cross bar 300 and the supporting jaws 400 are also adjusted along with the positioning sleeve 310 so that the positioning sleeve 310 can be positioned coaxially with the bearing 800. Since the two supporting jaws 400 are symmetrically distributed on the opposite sides of the positioning sleeve 310, the bearing 800 can be located in the middle of the two supporting jaws 400, and then the screw rod 200 is rotated in the opposite direction to make the screw rod 200 drive the cross bar 300 to rise, and drive the positioning sleeve 310 and the two The supporting jaws 400 rise, causing the positioning sleeve 310 to separate from the bearing 800. At the same time, since the two supporting jaws 400 are slidably connected to the cross bar 300, the two supporting jaws 400 move closer to each other to abut against the bottom of the bearing 800. The supporting jaws 400 support and drive the bearing 800 to rise, causing the motor 700 to rise together with the bearing 800, thereby completing the lifting and disassembly of the motor 700. The positioning sleeve 310 assists the position adjustment of the two supporting jaws 400, and the clamping position accuracy of the two supporting jaws 400 can be improved, so that the forces on both sides of the bearing 800 are balanced, and the shaking of the motor 700 and the twisting disk 900 are reduced, thereby improving the stability of the disassembly of the motor 700. In addition, the positioning and lifting and disassembly processes are controlled by the screw 200 above the motor 700, which is easy to operate and suitable for the disassembly of the motor 700 in a narrow space.

[0031] It should be noted that the positioning sleeve 310 can be provided with a positioning groove whose shape matches the bearing 800. The positioning sleeve 310 is sleeved on the outer side of the bearing 800 through the positioning groove, and the position of the positioning sleeve 310 is adjusted by utilizing the reaction force of the bearing 800 on the wall of the positioning groove.

[0032] The two supporting jaws 400 may be driven to move toward each other by a magnetic driving mechanism, or by an elastic telescopic mechanism, or by manually pushing the two supporting jaws 400 toward each other.

[0033] It is understandable that, referring to Figure 1 and Figure 3 The positioning sleeve 310 is provided with a tapered positioning hole 311, the aperture of which gradually decreases from bottom to top, and the bearing 800 can penetrate the tapered positioning hole 311 and abut against the wall of the tapered positioning hole 311 to locate the position of the positioning sleeve 310. When the cross bar 300 and the positioning sleeve 310 are driven down by the screw rod 200, since the aperture of the tapered positioning hole 311 gradually decreases from bottom to top, it is convenient for the bearing 800 to gradually penetrate the tapered positioning hole 311 along the inner wall of the positioning hole to gradually adjust the position of the positioning sleeve 310 until the bearing 800 abuts against the inner wall of the positioning hole circumferentially, thereby locating the position of the positioning sleeve 310, which can improve the stability of the adjustment and positioning process, and can be applicable to the sleeve connection and positioning of bearings 800 of different outer diameters, so as to improve the applicability of the motor disassembly device for the twisting machine.

[0034] It is understandable that, referring to Figure 1 , Figure 3 and Figure 5 The bracket 100 is provided with two vertical rods 110, and the vertical rods 110 are provided with slide grooves 111, which are arranged in the vertical direction, and the two ends of the cross bar 300 are respectively slidably connected to the slide grooves 111 of the two vertical rods 110. The slide grooves 111 are arranged in the vertical direction, and the two ends of the cross bar 300 are respectively slidably connected to the slide grooves 111 of the two vertical rods 110. The slide grooves 111 are used to guide and limit the lifting and lowering movement of the cross bar 300, which can reduce the shaking and deviation of the cross bar 300 during the lifting and lowering process, thereby improving the stability of the lifting and lowering movement of the cross bar 300, and further improving the stability of the lifting and lowering process of the motor 700.

[0035] Specifically, refer to Figure 1 , Figure 3 and Figure 5 The two ends of the cross bar 300 are respectively fixedly connected to the limit blocks 320, and the two limit blocks 320 respectively abut the sides of the two vertical rods 110 that are away from each other to limit the horizontal movement of the cross bar 300. By the two limit blocks 320 respectively abutting the sides of the two vertical rods 110 that are away from each other, the movement of the cross bar 300 is limited along the length direction of the cross bar 300 to limit the horizontal movement of the cross bar 300, which can reduce the possibility of horizontal shaking during the lifting process of the cross bar 300, so as to improve the stability of the lifting movement of the cross bar 300, and further improve the stability of the lifting and disassembly process of the motor 700.

[0036] It should be noted that rollers can be respectively provided on the sides of the two limit blocks 320 facing each other. The limit blocks 320 abut against one side of the vertical rod 110 through the rollers, which can reduce the friction resistance between the limit blocks 320 and the vertical rod 110 to improve the smoothness of the lifting and lowering movement of the cross bar 300.

[0037] It is understandable that, referring to Figure 3 The cross bar 300 is provided with a positioning through hole 330, the screw rod 200 is inserted in the positioning through hole 330, and one end of the screw rod 200 close to the cross bar 300 is fixedly connected with two support blocks 340, and the two support blocks 340 respectively abut the upper and lower sides of the cross bar 300. The cross bar 300 is provided with a positioning through hole 330, and the screw rod 200 is inserted in the positioning through hole 330, so that the screw rod 200 can be radially positioned, and the possibility of shaking and tilting of the screw rod 200 can be reduced, so as to improve the stability of the motor 700 during the lifting and disassembly process. Moreover, because the two support blocks 340 fixedly connected to the cross bar 300 respectively abut the upper and lower sides of the cross bar 300, the cross bar 300 can be limited up and down to locate the height position of the cross bar 300 on the screw rod 200, and the possibility of shaking up and down or tilting and shaking of the cross bar 300 during the lifting and lowering process can be reduced, so as to improve the stability of the lifting and lowering movement of the cross bar 300, thereby improving the stability of the motor 700 during the lifting and disassembly process.

[0038] It should be noted that the lifting and lowering movement of the cross bar 300 is driven by the support block 340 abutting against the cross bar 300 . The support block 340 rotates with the screw rod 200 , while the cross bar 300 does not rotate with the screw rod 200 .

[0039] It is understandable that, referring to Figure 1 , Figure 3 and Figure 4 The crossbar 300 is provided with two guide grooves 350, which are symmetrically distributed on opposite sides of the positioning sleeve 310, and the two guide grooves 350 are inclined downward in a horizontal direction close to each other. The support jaws 400 are provided with guide rods 410, and the guide rods 410 are slidably connected to the guide grooves 350. Since the guide grooves 350 are symmetrically distributed on opposite sides of the positioning sleeve 310, and the two guide grooves 350 are inclined downward in a horizontal direction close to each other, the guide rods 410 slide along the guide grooves 350, so that the two support jaws 400 move downward and approach each other, and move upward and move away from each other. When the support jaws 400 support and drive the bearing 800 to rise, the bearing 800 applies downward pressure to the support jaws 400, so that the support jaws 400 move downward and approach each other, and prevent the bearing 800 from slipping and falling due to the two support jaws 400 moving away from each other, thereby improving the reliability of the motor 700 rising and disassembling process.

[0040] It is understandable that, referring to Figure 1 , Figure 3 and Figure 4 The two supporting jaws 400 are provided with abutting portions 420 on the sides facing each other. The abutting portions 420 are used to abut the bottom of the bearing 800. The bottom surfaces of the two abutting portions 420 are inclined upward in a horizontal direction close to each other. Since the bottom surfaces of the two abutting portions 420 are inclined upward in a horizontal direction close to each other, when the screw rod 200 drives the cross bar 300 to descend, the bottom surface of the abutting portion 420 abuts against the top of the bearing 800. The bearing 800 applies a reverse force to the abutting portion 420, and drives the two supporting jaws 400 to move away from each other and open through the inclined surface, so that the positioning sleeve 310 is conveniently sleeved on the outside of the bearing 800 to locate the position of the positioning sleeve 310, and there is no need to manually open the two supporting jaws 400, thereby improving the convenience of using the motor disassembly device for the twisting machine.

[0041] Specifically, refer to Figure 1 , Figure 3 and Figure 4 The abutting portion 420 is used to abut against the bearing 800. A plurality of raised strips 421 are evenly spaced on one side thereof, and the raised strips 421 can abut against the bottom of the bearing 800. By evenly spaced on one side thereof, and by abutting against the bottom of the bearing 800 by the raised strips 421, the friction resistance between the abutting portion 420 and the bearing 800 can be increased, and the bearing 800 can be prevented from slipping and falling due to the two supporting jaws 400 moving away from each other, thereby improving the reliability of the lifting and disassembly process of the motor 700.

[0042] It is understandable that, referring to Figure 1 , Figure 2 and Figure 5 The bottom of the bracket 100 is fixedly connected with two arc-shaped support seats 500, which are arranged on opposite sides of the bracket 100, and the support seats are used to support the bracket 100. By fixing the arc-shaped support seats 500 on opposite sides of the bracket 100, the arc-shaped support seats 500 are evenly stressed along the arc surface, and the friction resistance between the arc-shaped support seats 500 and the platform is increased, which can reduce the possibility of shaking of the bracket 100, thereby improving the stability of the motor 700 during the lifting and disassembly process.

[0043] It should be noted that an anti-sliding block 510 can be provided at the bottom of the arc-shaped support seat 500 to increase the friction resistance between the arc-shaped support seat 500 and the platform, further reducing the possibility of shaking of the bracket 100, thereby improving the stability of the motor 700 during the lifting and disassembly process.

[0044] It is understandable that, referring to Figures 1 to 3The end of the screw rod 200 away from the cross bar 300 is connected with a handle 600. By connecting the end of the screw rod 200 away from the cross bar 300 with the handle 600, it is convenient for the user to apply force to rotate the screw rod 200, thereby improving the convenience of use of the motor disassembly device for the twisting machine.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
