Description

Technical Field

[0001] This utility model belongs to the field of disassembly technology, and specifically relates to a manual disassembly device for disassembling glued parts of an electric motor. Background Technology

[0002] As the motor industry has developed, customers have increasingly higher requirements for motor performance, and waterproofing has become more and more important. Currently, the mainstream waterproofing method is to apply glue to the joint surfaces between components. However, after the glue has cured, the components cannot be separated even after the fastening screws are removed, which makes it very difficult to repair the motor. Using machinery to forcibly disassemble the components will damage them and increase costs. Utility Model Content

[0003] This utility model addresses the problems in the prior art by providing a manual disassembly tool for removing glued parts of a motor. The specific technical solution is as follows:

[0004] A manual disassembly tool for removing glued parts of an electric motor, used to separate the motor end cover and the motor housing, includes a fixing frame, one end of which is connected to four screws. In the installed state, the other ends of the four screws are screwed into the four screw holes of the motor end cover.

[0005] The other end of the fixed frame is connected to a sliding rod, and a sliding cylinder is slidably connected to the sliding rod. The other end of the sliding rod has a plug that restricts the sliding cylinder. The sliding cylinder is driven by an external force to slide on the sliding rod and hit the plug to separate the motor end cover and the motor housing.

[0006] As a further technical solution of this utility model, the fixing frame is a rectangular structure, which includes four "L"-shaped frames. The four "L"-shaped frames are respectively connected to four screws. The four "L"-shaped frames are distributed at the four corners of the rectangular structure with the corners facing outwards. A sleeve is connected between two adjacent "L"-shaped frames, and the "L"-shaped frames and the sleeves are slidably connected.

[0007] As a further technical solution of this utility model, the sliding rod and the fixing frame are detachably connected.

[0008] As a further technical solution of this utility model, a through hole is provided at the corner of the "L"-shaped frame along the thickness direction, and the end of the screw away from the motor end cover passes through the through hole and is rotatably connected to a nut.

[0009] As a further technical solution of this utility model, the fixing frame also includes a cross bracket, which is placed at the center of the rectangular structure. The four extensions of the cross bracket pass through four sleeves respectively, and the sliding rod is connected to the center of the cross bracket.

[0010] As a further technical solution of this utility model, a pressing bolt is provided between the sleeve and the "L"-shaped frame. The pressing bolt is rotatably connected to the sleeve and presses against the "L"-shaped frame.

[0011] The beneficial effects of this utility model are as follows:

[0012] (1) In this application, the device can be connected to the motor end cover by a screw. After the two are connected, the drive slide cylinder slides back and forth on the slide rod and intermittently hits the plug, thereby driving the entire device and the motor end cover to move away from the motor housing, thereby separating the motor end cover and the motor housing.

[0013] (2) In this application, the fixing frame is also set as a relatively sliding rectangular structure, which can adjust the length of the four sides of the rectangular structure, that is, can adjust the distribution position of the four screws, so that it can be applied to motor end caps of different specifications, thereby improving the applicability of the device.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Figure 1 A schematic diagram of the overall structure of a manual disassembly tool for removing glued parts of an electric motor is shown. Figure 1This invention discloses a manual disassembly device for removing adhesive-coated parts from a motor, used to separate a motor end cover 200 and a motor housing 300. It includes a fixing frame 110, one end of which is connected to four screws 120. In the installed state, the other ends of the four screws 120 are screwed into the four screw holes of the motor end cover 200. The other end of the fixing frame 110 is connected to a sliding rod 130, on which a sliding cylinder 140 is slidably connected. The other end of the sliding rod 130 has a plug 131 that restricts the sliding cylinder 140. The sliding cylinder 140 is driven by an external force to slide on the sliding rod 130 and impact the plug 131 to separate the motor end cover 200 and the motor housing 300. In this application, the end face of the motor end cover 200 has screw holes for connection with the motor housing 300. This device can connect the screws 120 to the motor end cover 200. After connection, the sliding cylinder 140 is driven to slide on the sliding rod 130. The sliding rod 140 reciprocates and intermittently impacts the plug 131, thereby driving the entire device and the motor end cover 200 away from the motor housing 300, thus separating the motor end cover 200 from the motor housing 300. It should be noted that in this embodiment, the slide cylinder 140 is manually driven, that is, the slide cylinder 140 is manually held and external force is applied. However, in some other embodiments, the slide cylinder 140 can adopt other driving methods, such as hydraulic push rod drive, motor drive, etc., which will not be described in detail in this application. The slide rod 130 is detachably connected to the fixing frame 110. That is to say, the slide rod 130 and the fixing frame 110 can be stored separately, which is beneficial to saving storage space and also to replacing parts. For example, the slide rod 130 and the fixing frame 110 are threadedly connected, and the two can be connected and separated by relative rotation; or they can be connected by bolts, snap-fit, etc., which will not be limited in this application.

[0021] Figure 2 A schematic diagram of the structure of the fixing frame 110 is shown; Figure 3 An exploded view of the fixture 110 is shown; Figure 2 and Figure 3 In the middle, the fixing frame 110 is a rectangular structure, including four "L"-shaped frames 111. The four "L"-shaped frames 111 are respectively connected to four screws 120. The four "L"-shaped frames 111 are distributed at the four corners of the rectangular structure with the corners facing outwards. A sleeve 112 connects adjacent "L"-shaped frames 111, and the "L"-shaped frames 111 and sleeves 112 are slidably connected. Through this structure, the four side lengths of the rectangular structure can be adjusted, that is, the distribution position of the four screws 120 can be adjusted, thereby enabling its application to motor end covers 200 of different specifications, improving the applicability of the lifting device; for details, see... Figure 3The rectangular structure is composed of two sides L1 and two sides L2 connected alternately. Adjusting the length of side L2 involves driving the two sides L1 to slide along the X direction within the sleeve 112 of L2, thus adjusting the length of side L2. Adjusting the length of side L1 involves driving the two sides L2 to slide along the Y direction within the sleeve 112 of L1, thus adjusting the length of side L1. A through hole 114 is provided at the corner of the "L"-shaped frame 111 along the thickness direction. The end of the screw 120 away from the motor end cover 200 passes through the through hole 114 and is rotatably connected to a nut 121. This allows the fixing frame 110 and the screw 120 to be detachably connected. When the nut 121 is screwed onto the screw 120, it prevents the screw 120 from detaching from the fixing frame 110. When the nut 121 is unscrewed from the screw 120, the screw 120 can detach from the fixing frame 110 through the through hole 114, achieving a detachable connection. The fixing frame 110 also includes a "+" The "+" bracket 113 is placed at the center of the rectangular structure. The four extensions of the "+" bracket 113 pass through the four sleeves 112 respectively. The sliding rod 130 is connected to the center of the "+" bracket 113. The "+" bracket 113 can connect the entire fixed frame 110 and the sliding rod 130. The center of the "+" bracket 113 is also the center of the rectangular structure. When the sliding rod 130 applies a pulling force to the screw 120, it can make the pulling force on the motor end cover 200 uniform, which is conducive to the parallel movement of the motor end cover 200 and is not easy to tilt. A pressing bolt 115 is provided between the sleeve 112 and the "L" shaped frame 111. The pressing bolt 115 is rotatably connected to the sleeve 112 and presses against the "L" shaped frame 111. After the rectangular structure is adjusted, the pressing bolt 115 is rotated to press the "L" shaped frame 111, which can ensure the stability of the rectangular structure.

[0022] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
