Description

Technical Field

[0001] This application relates to the field of motor assembly positioning fixture technology, and in particular to a motor end cover assembly fixture. Background Technology

[0002] Fixtures are a type of process equipment primarily used in manufacturing processes to fix and position workpieces, ensuring precise positioning during machining and reducing machining difficulty. Fixtures play a crucial role in machining, significantly improving production efficiency and product quality.

[0003] The related technology discloses a servo motor, with reference to Figure 1 The device includes a stator 01 and a rotor 02. A coil 03 is provided on the stator 01. A front cover 04 and a rear cover 05 are respectively provided at both ends of the stator 01. The coil 03 is located on the same sides of the front cover 04 and the rear cover 05. Bolts 06 are slidably passed through both ends of the stator 01. The front cover 04 and the rear cover 05 are slidably sleeved on the bolts 06. Nuts 07 are threadedly connected to the bolts 06. The nuts 07 are used to abut against the rear cover 05. A brush 08 is bolted to the rear cover 05. The terminal of the brush 08 is close to the nut 07 on the bolt 06.

[0004] During the assembly of the aforementioned motor, due to the structural design of the servo motor, the installation position of the brush terminal is designed to be close to the nut. Since the nut is not large, the workers will find it difficult to tighten the nut onto the bolt due to the influence of the brush terminal, which greatly affects the assembly efficiency of the motor and has shortcomings. Utility Model Content

[0005] To address the problem of nuts on motors being difficult to tighten onto bolts, this application provides a motor end cover assembly fixture.

[0006] The technical solution for a motor end cover assembly fixture provided in this application is as follows:

[0007] A motor end cover assembly fixture includes a base plate, a positioning block provided on the base plate, a positioning groove for inserting a rear end cover of the motor on the positioning block, clamping plates slidably provided on the base plate and on both sides of the positioning block, the clamping plates having placement grooves for accommodating nuts, and a driving assembly for driving the clamping plates to slide on the base plate.

[0008] By adopting the above technical solution, the worker first places the nut in the placement slot on the clamping plate, then inserts the rear end cover of the motor into the positioning slot on the positioning block. Then, the drive component causes the clamping plates on both sides of the positioning block to move the nut closer to the rear end cover of the motor until the clamping plates stop moving. At this time, the nut is located at the installation position of the rear end cover of the motor. Finally, the worker inserts and tightens the bolt to screw the nut onto the bolt, thereby realizing the rapid assembly of the motor.

[0009] Optionally, the driving assembly includes a first guide rail symmetrically arranged on both sides of the positioning block, a first slider slidably arranged on the first guide rail, a driving plate arranged on the first slider, a clamping plate arranged on the driving plate, and an opening and closing member arranged on the base plate. The opening and closing member is used to control the driving plates on both sides of the positioning block to move closer to each other or further apart.

[0010] By adopting the above technical solution, under the guidance of the first slider and the first guide rail, the drive plates on both sides of the opening and closing component drive the positioning block to move closer to each other, thereby causing the drive plates to move the nuts on the clamps closer to the positioning block, thus moving the nuts to the installation position of the motor's rear end cover, thereby reducing the difficulty for workers to tighten the nuts.

[0011] Optionally, the opening and closing component includes a push-pull quick clamp disposed on the base plate. The base plate is provided with a second guide rail perpendicular to the first guide rail. A push plate is slidably disposed on the second guide rail. The push plate is disposed on the push rod of the push-pull quick clamp. A linkage rod with an L-shaped cross-section is rotatably disposed on the base plate. A first sleeve and a second sleeve are respectively disposed at both ends of the linkage rod. A first waist-shaped hole is opened on the drive plate along the length direction of the second guide rail. The first waist-shaped hole slides with the first sleeve. A second waist-shaped hole is opened on the push plate along the length direction of the first guide rail. The second waist-shaped hole slides with the second sleeve.

[0012] By adopting the above technical solution, the worker pushes the push-pull quick clamp. Under the guidance of the second guide rail, the push rod of the push-pull quick clamp drives the push plate to approach the positioning block. The second oblong hole on the push plate pushes the second sleeve on the linkage rod. The linkage rod rotates around its rotation center, thereby causing the first sleeve on the linkage rod to push the first oblong hole. Due to the guiding effect of the first guide rail and the first slider, the drive plate moves closer to the positioning block, thereby causing the drive plates on both sides of the positioning block to drive the nuts on the clamps to move closer to each other towards the positioning block.

[0013] Optionally, a handle is provided on the base plate.

[0014] By adopting the above technical solution, it is easier for workers to move the base plate and the difficulty of moving the base plate is reduced.

[0015] Optionally, the opening and closing component includes an intermediate plate disposed on the base plate and located between the two drive plates. A compression spring supports the intermediate plate and the drive plates. A winding wheel is rotatably disposed on the intermediate plate. A pull rope is disposed between the winding wheel and the drive plate. A locking rod is vertically slidably disposed on the winding wheel. The intermediate plate has multiple slots for the locking rod to be inserted into. The multiple slots are circumferentially distributed along the axis of the winding wheel.

[0016] By adopting the above technical solution, the worker pulls up the locking rod and rotates the winding wheel. The winding wheel winds the pull rope, and the pull rope drives the drive plates on both sides of the positioning block to move closer to each other. During this process, the compression spring is continuously compressed until the drive plate stops moving. Then the worker inserts the locking rod into the slot on the middle plate, so that the drive plates on both sides of the positioning block simultaneously drive the nuts on the clamping plate to move closer to each other.

[0017] Optionally, a reversing wheel is rotatably mounted on the intermediate plate, and the pull rope passes around the reversing wheel.

[0018] By adopting the above technical solution, during the winding process of the winding wheel, the reversing wheel facilitates the direction of the rope to transmit tension, thereby facilitating the simultaneous approach of the drive plates on both sides of the positioning block.

[0019] Optionally, a handle is slidably mounted coaxially on the locking rod.

[0020] By adopting the above technical solution, it is convenient for workers to rotate the winding wheel, and at the same time, workers can pull out or insert the locking rod.

[0021] Optionally, a tension spring is provided between the locking rod and the winding wheel.

[0022] By adopting the above technical solution, when the worker pulls the handle and disengages the locking rod from the slot on the middle plate, the tension spring is stretched. The worker then rotates the handle to cause the winding wheel to wind up the rope. During the rotation of the winding wheel, the worker gradually lowers the handle. When the locking rod slides back above the slot on the middle plate, the tension spring returns to its original shape and drives the locking rod to re-insert into the slot on the middle plate. This reduces the possibility of the rope being damaged due to the worker over-winding the rope.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The worker first places the nut in the placement slot on the clamping plate, then inserts the rear end cover of the motor into the positioning slot on the positioning block. Then, the drive assembly causes the clamping plates on both sides of the positioning block to move the nut closer to the rear end cover of the motor until the clamping plates stop moving. At this time, the nut is located at the installation position of the rear end cover of the motor. Finally, the worker inserts and tightens the bolt to screw the nut onto the bolt, thus achieving rapid assembly of the motor.

[0025] 2. The worker pushes the push-pull quick clamp. Under the guidance of the second guide rail, the push rod of the push-pull quick clamp drives the push plate to approach the positioning block. The second oblong hole on the push plate pushes the second sleeve on the linkage rod. The linkage rod rotates around its rotation center, thereby causing the first sleeve on the linkage rod to push the first oblong hole. Due to the guiding effect of the first guide rail and the first slider, the drive plate moves closer to the positioning block, thereby causing the drive plates on both sides of the positioning block to drive the nuts on the clamp plate to move closer to each other towards the positioning block.

[0026] 3. The worker pulls up the locking rod and rotates the winding wheel. The winding wheel winds the pull rope, which causes the drive plates on both sides of the positioning block to move closer to each other. During this process, the compression spring is continuously compressed until the drive plates stop moving. Then the worker inserts the locking rod into the slot on the middle plate, so that the drive plates on both sides of the positioning block simultaneously drive the nuts on the clamps to move closer to each other.

Detailed Implementation

[0033] The following is in conjunction with the appendix Figures 2-5 This application will be described in further detail.

[0034] This application discloses a motor end cover assembly fixture.

[0035] Example 1

[0036] Reference Figure 2 A motor end cover assembly fixture includes a base plate 1, a positioning block 2 welded on the base plate 1, handles 8 bolted to the base plate 1 on both sides of the positioning block 2, a positioning groove 3 for inserting the rear end cover 05 of the motor on the positioning block 2, clamping plates 4 slidably arranged on the base plate 1 and on both sides of the positioning block 2, a placement groove 5 for accommodating nuts 07 on the clamping plates 4, and a drive assembly 6 for driving the clamping plates 4 to slide on the base plate 1.

[0037] Reference Figure 2 and Figure 3 The drive assembly 6 includes a first guide rail 61 symmetrically bolted to both sides of the positioning block 2, a first slider 62 slidably arranged on the first guide rail 61, a drive plate 63 bolted to the first slider 62, a clamping plate 4 bolted to the drive plate 63, and an opening and closing member 7 arranged on the base plate 1. The opening and closing member 7 is used to control the drive plates 63 on both sides of the positioning block 2 to move closer to each other or further away from each other.

[0038] The worker first places the nut 07 in the placement groove 5 on the clamping plate 4, and then inserts the rear end cover 05 of the motor into the positioning groove 3 on the positioning block 2 for fixation. Under the guidance of the first guide rail 61 and the first slider 62, the drive plates 63 on both sides of the positioning block 2 are brought closer to each other through the opening and closing piece 7.

[0039] This causes the drive plate 63 to move the nut 07 on the clamping plate 4 to the installation position of the rear end cover 05 of the motor. Then, the worker inserts the bolt 06 and tightens the bolt 06 with a tool, so that the nut 07 is tightened on the bolt 06, and then the nut 07 is pressed against the rear end cover 05 of the motor, thus completing the assembly of the motor.

[0040] Reference Figure 2 and Figure 3 The opening and closing component 7 includes a push-pull quick clamp 701 bolted to the base plate 1. A second guide rail 702 perpendicular to the length direction of the first guide rail 61 is bolted to the base plate 1. A push plate 703 is slidably arranged on the second guide rail 702. The push plate 703 is bolted to the push rod of the push-pull quick clamp 701. A linkage rod 704 with an L-shaped cross section is rotatably connected to the base plate 1.

[0041] Reference Figure 2 and Figure 3The two ends of the linkage rod 704 are respectively welded with a first sleeve 705 and a second sleeve 706. A first waist-shaped hole 707 is opened on the drive plate 63 along the length direction of the second guide rail 702. The first waist-shaped hole 707 is slidably engaged with the first sleeve 705. A second waist-shaped hole 708 is opened on the push plate 703 along the length direction of the first guide rail 61. The second waist-shaped hole 708 is slidably engaged with the second sleeve 706.

[0042] The worker pushes the push-pull quick clamp 701, and under the guidance of the second guide rail 702, the push rod of the push-pull quick clamp 701 drives the push plate 703 to gradually approach the positioning block 2. The second oblong hole 708 on the push plate 703 pushes the second sleeve 706 on the linkage rod 704. The second sleeve 706 and the second oblong hole 708 slide relative to each other, thereby causing the linkage rod 704 to rotate around its rotation center.

[0043] This causes the first sleeve 705 on the linkage rod 704 to rotate around the rotation center of the linkage rod 704. Due to the guiding effect of the first guide rail 61 and the first slider 62, the first sleeve 705 slides relative to the first oblong hole 707, causing the drive plate 63 to move closer to the positioning block 2. This causes the drive plates 63 on both sides of the positioning block 2 to simultaneously drive the nuts 07 on the clamping plate 4 to move closer to each other in the positioning block 2.

[0044] The implementation principle of Example 1 is as follows: The worker first places the nut 07 in the placement groove 5 on the clamping plate 4, and then inserts the rear end cover 05 of the motor into the positioning groove 3 on the positioning block 2 for fixation. Under the guidance of the first guide rail 61 and the first slider 62, the drive plates 63 on both sides of the positioning block 2 are brought closer to each other through the opening and closing part 7.

[0045] This causes the drive plate 63 to move the nut 07 on the clamping plate 4 to the installation position of the rear end cover 05 of the motor. Then, the worker inserts the bolt 06 and tightens the bolt 06 with a tool, so that the nut 07 is tightened on the bolt 06, and then the nut 07 is pressed against the rear end cover 05 of the motor, thus completing the assembly of the motor.

[0046] The worker pushes the push-pull quick clamp 701, and under the guidance of the second guide rail 702, the push rod of the push-pull quick clamp 701 drives the push plate 703 to gradually approach the positioning block 2. The second oblong hole 708 on the push plate 703 pushes the second sleeve 706 on the linkage rod 704. The second sleeve 706 and the second oblong hole 708 slide relative to each other, thereby causing the linkage rod 704 to rotate around its rotation center.

[0047] This causes the first sleeve 705 on the linkage rod 704 to rotate around the rotation center of the linkage rod 704. Due to the guiding effect of the first guide rail 61 and the first slider 62, the first sleeve 705 slides relative to the first oblong hole 707, causing the drive plate 63 to move closer to the positioning block 2. This causes the drive plates 63 on both sides of the positioning block 2 to simultaneously drive the nuts 07 on the clamping plate 4 to move closer to each other in the positioning block 2.

[0048] Example 2

[0049] refer to Figure 4 and Figure 5 The difference between this embodiment and embodiment 1 is that the opening and closing component 7 includes an intermediate plate 709 bolted to the base plate 1 and located between two drive plates 63. A compression spring 710 supports the intermediate plate 709 and the drive plate 63. A winding wheel 711 is rotatably connected to the intermediate plate 709. A pull rope 712 is attached between the winding wheel 711 and the drive plate 63.

[0050] refer to Figure 4 and Figure 5 A reversing wheel 9 is symmetrically connected to the positioning block 2 on the intermediate plate 709. A pull rope 712 passes around the reversing wheel 9. A locking rod 713 is vertically slidably arranged on the winding wheel 711. A handle 10 is coaxially slidably arranged on the locking rod 713. A tension spring 11 is arranged between the locking rod 713 and the winding wheel 711. Two slots 714 are provided on the intermediate plate 709 for the locking rod 713 to be inserted. The two slots 714 are circumferentially distributed along the axis of the winding wheel 711.

[0051] The implementation principle of Example 2 is as follows: the worker pulls up the handle 10, the handle 10 drives the locking rod 713 to continuously disengage from the slot 714 on the intermediate plate 709, the tension spring 11 is continuously stretched, and then the worker rotates the winding wheel 711 through the handle 10, the winding wheel 711 winds the pull rope 712, and under the reversing action of the reversing wheel 9, the pull rope 712 drives the drive plates 63 on both sides of the positioning block 2 to move closer to each other.

[0052] During this process, the compression spring 710 is continuously compressed until the locking rod 713 moves above the slot 714. Then the tension spring 11 restores its deformation and drives the locking rod 713 to insert into the slot 714 on the intermediate plate 709. At this time, the drive plate 63 stops moving, and at the same time, the drive plates 63 on both sides of the positioning block 2 drive the nuts 07 on the clamping plate 4 to move closer to each other in the positioning block 2.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
