The bottom of the housing 1 on the side away from the opening in the width direction is bent inward to form a flange 6, and the bottom of the housing 1 on the side away from the opening in the width direction is located at both ends of the flange 6 and integrally formed with limit blocks 8.

[0028] Two fixing members 4 are installed on the side plate 22. In the present application, the fixing members 4 can be bolts. The fixing members 4 pass through the side plate 22 and are threadedly fixed in the housing 1. When installing the housing 1, first place the flange 6 of the housing 1 under the convex strip 5 of the bottom plate 21, then place the two limit blocks 8 of the housing 1 in the two limit grooves 7 of the bottom plate 21, and finally rotate and install the two fixing members 4 to fix the side plate 22 and the housing 1.

[0029] The flange 6 is in contact with the convex strip 5, and the two limit blocks 8 are located in the two limit grooves 7, so that the bottom plate 21 and the shell 1 can be connected. The side wall of the open end in the width direction of the shell 1 is pressed against the side wall of the side plate 22 close to the bottom plate 21, and the bottom wall of the shell 1 is pressed against the top wall of the bottom plate 21, so that the shell 1 and the base 2 can be tightly connected.

[0030] The housing 1 and the base 2 can be fixedly connected by using two fixing members 4. When the housing 1 needs to be disassembled, only the two fixing members 4 need to be disassembled to quickly remove the housing 1 from the base 2, thereby facilitating the maintenance of the motion controller by the staff.

[0031] The housing 1 and the bottom plate 21 are assembled to form a rectangular outer cover structure, and the circuit board assembly 3 is mounted on the bottom plate 21 and is located inside the outer cover structure. Ventilation holes 10 are provided at both ends of the housing 1 in the length direction, and the vents 10 can dissipate heat from the motion controller when the motion controller is in use.

[0032] Reference Figure 4 The circuit board assembly 3 includes a power board 31, a signal board 32, six first fasteners 33 and second fasteners 34, and three mounting seats 9 are fixedly installed on the bottom of the side wall of the side plate 22 close to the bottom plate 21 and the top wall of the bottom plate 21, and the power board 31 is placed on multiple mounting seats 9.

[0033] The first fastener 33 is in the shape of a hexagonal column, the bottom end of the first fastener 33 is a threaded column, and a thread groove is formed at the top end of the first fastener 33. The threaded column at the bottom end of the first fastener 33 passes through the power board 31 and is threadedly fixedly installed on the mounting seat 9, so that the power board 31 can be fixedly installed on the base 2. Three hexagonal connecting columns 11 are fixedly installed on the top wall of the power board 31, and a thread groove is formed at the top end of the hexagonal connecting columns 11. The signal board 32 is placed on the six first fasteners 33 and the three hexagonal connecting columns 11.

At the same time, the second fastener 34 passes through the signal plate 32 and is threadedly fixed in the thread groove at the top of the hexagonal connecting column 11, so that the signal plate 32 can be fixedly installed on the base 2.

[0035] The implementation principle of a motion controller in Example 1 of the present application is as follows: when assembling the shell 1 and the base 2, first place the flange 6 of the shell 1 under the convex strip 5 of the bottom plate 21, then place the two limit blocks 8 of the shell 1 in the two limit grooves 7 of the bottom plate 21, and finally rotate and install the two fixings 4 to fix the side plate 22 and the shell 1. The flange 6 abuts against the convex strip 5, and the two limit blocks 8 are located in the two limit grooves 7, so that the bottom plate 21 and the shell 1 can be connected. The two fixings 4 can be used to fix the shell 1 and the base 2. When the shell 1 needs to be disassembled, only the two fixings 4 need to be disassembled to quickly remove the shell 1 from the base 2, so that it is convenient for the staff to repair the motion controller.

[0036] Embodiment 2: Reference Figure 5 and Figure 6 The difference between this embodiment and the first embodiment is that the fixing member 4 includes a rotating ring 41 and a fixing column 42, the fixing column 42 passes through the side plate 22 and is threadedly fixed in the housing 1, and the rotating ring 41 is rotatably installed at the end of the fixing column 42 away from the housing 1 with the diameter direction of the fixing column 42 as the rotation axis. A receiving groove 25 is provided on the side wall of the side plate 22 away from the housing 1, and two limit clips 26 are installed in the side plate 22 in the receiving groove 25.

[0037] When the housing 1 and the base 2 are assembled, the fixing column 42 is passed through the side plate 22 and inserted into the housing 1, and the fixing column 42 is driven to rotate by the rotating ring 41. The fixing column 42 is fixedly connected to the side plate 22 and the housing 1, and the housing 1 and the base 2 can be fixedly connected. Then, the rotating ring 41 is rotated into the receiving groove 25, and the limiting clamp 26 clamps the rotating ring 41.

[0038] When the signal board 32 needs to be disassembled for maintenance, the swivel 41 is removed from the limit clamp 26, and the swivel 41 is rotated out of the receiving groove 25. The swivel 41 is used to drive the fixing column 42 to rotate. After the fixing column 42 rotates out of the housing 1, the housing 1 can be quickly removed from the base 2.

[0039] Reference Figure 7 , Figure 8 and Fig. 9 The first fastener 33 and the top of the hexagonal connecting column 11 are integrally formed with the connecting column 11, and the connecting column 11 passes through the signal plate 32. A first slide groove 12 is provided on the side wall of the connecting column 11 along its own axial direction, and the top of the first slide groove 12 extends to the top of the connecting column 11 and is openly arranged. A second slide groove 13 is provided on the side wall of the connecting column 11 at the bottom of the first slide groove 12, and the second slide groove 13 is provided along the circumference of the connecting column 11.

[0040] A first guide groove 14 is obliquely provided on the side wall of the connecting column 11 between the bottom end of the first slide groove 12 and the end of the second slide groove 13. The first guide groove 14 connects the first slide groove 12 and the second slide groove 13, and the first guide groove 14 gradually tilts downward from the first slide groove 12 to the second slide groove 13.

[0041] A first locking groove 16 and a second locking groove 17 are provided on the side wall of the connecting column 11 at the end of the second slide groove 13 away from the first guide groove 14. The first locking groove 16 and the second locking groove 17 are both provided along the axial direction of the connecting column 11. The first locking groove 16 is located above the second slide groove 13, and the second locking groove 17 is located below the second slide groove 13. In addition, two first slide grooves 12, the first guide groove 14, the second slide groove 13, the first locking groove 16 and the second locking groove 17 are symmetrically provided along the radial direction of the connecting column 11.

[0042] Reference Fig. 9 and Fig.10 The second fastener 34 includes a fastening ring 341, an elastic washer 343 and two locking blocks 342. The elastic washer 343 is installed on the bottom wall of the fastening ring 341. In the present application, the elastic washer 343 can be selected as a rubber pad. The two locking blocks 342 are fixedly installed on the inner side wall of the fastening ring 341 along the radial direction of the fastening ring 341 symmetrically. The fastening ring 341 and the elastic washer 343 are both slidably sleeved on the connecting column 11. The fastening ring 341 can drive the locking blocks 342 to slide in the first slide groove 12, the first guide groove 14, the second slide groove 13, the first locking groove 16 and the second locking groove 17.

[0043] When the second fastener 34 is used to fix the signal plate 32, the fastening ring 341 is slidably mounted on the connecting column 11, and the fastening ring 341 drives the elastic gasket 343 and the two locking blocks 342 to move. The two locking blocks 342 slide downward in the two first slide grooves 12. When the elastic gasket 343 slides downward and abuts the signal plate 32, the locking block 342 moves to the end of the first guide groove 14 close to the first slide groove 12.

[0044] Then, the fastening ring 341 is rotated, and the fastening ring 341 drives the locking block 342 to slide in the first guide groove 14. The first guide groove 14 guides the movement of the locking block 342, so that the locking block 342 moves downward at an angle. The locking block 342 drives the fastening ring 341 to move slightly downward, so that the fastening ring 341 squeezes the elastic gasket 343.

[0045] The locking block 342 moves through the first guide groove 14 to the second slide groove 13. When the locking block 342 moves to the end of the second slide groove 13 away from the first guide groove 14, the elastic gasket 343 releases its elastic potential energy and pushes the fastening ring 341 to slide upward. The fastening ring 341 drives the locking block 342 to slide upward. The locking block 342 rises from the second slide groove 13 and moves to the first locking groove 16, thereby being able to preliminarily lock the signal board 32.

[0046] Reference Fig.10 , Fig.11 and Fig.12 Two push rods 20 are symmetrically installed in the fastening ring 341 along its radial direction. The push rods 20 are slidably installed in the fastening ring 341 along the axial direction of the fastening ring 341, and the top ends of the push rods 20 extend out of the top wall of the fastening ring 341. Two locking rods 19 are symmetrically installed in the fastening ring 341 along its radial direction. The locking rods 19 are slidably installed in the fastening ring 341 along the radial direction of the fastening ring 341.

[0047] Reference Fig. 9 , Fig.10 and Fig.12 The ends of the two locking rods 19 that are away from each other and the bottom ends of the two push rods 20 are both set in a wedge shape and abut against each other. The ends of the two locking rods 19 that are away from each other pass through the two locking blocks 342, and the ends of the two locking rods 19 that are close to each other are rotatably installed with rollers 24. The inner wall of the connecting column 11 located at the second locking groove 17 is provided with a third locking groove 18 along its own radial direction. The two locking rods 19 in the fastening ring 341 are sleeved with elastic members 23, and a push ring 27 is fixedly installed on the locking rod 19. The end of the elastic member 23 away from the connecting column 11 abuts against the side wall of the push ring 27 close to the connecting column 11. In this application, the elastic member 23 can be selected as a spring.

[0048] After the signal board 32 is initially locked, the housing 1 and the base 2 are assembled. During the assembly of the housing 1, the top wall of the inner cavity of the housing 1 first abuts against the tops of the two push rods 20 extending from the top of the fastening ring 341. The push rods 20 drive the rollers 24 to abut against the connecting column 11 through the locking rods 19. Under the action of the rollers 24, the push rods 20 drive the fastening ring 341 to slide downward, and the fastening ring 341 drives the locking block 342 to slide downward, and the locking block 342 slides from the first locking groove 16 to the second locking groove 17.

[0049] When the locking block 342 slides into the second locking groove 17, the locking block 342 drives the locking rod 19 to move to the third locking groove 18, and the push rod 20 slides downward and pushes the locking rod 19 to insert into the third locking groove 18. The locking block 342 and the second locking groove 17 are first locked, and the locking rod 19 and the third locking groove 18 are second locked, so that the locking effect of the second fastener 34 is better.

[0050] The connecting column 11 is located at the top wall of the third locking groove 18 near the second locking groove 17, and the second guide groove 15 is inclined upward from the third locking groove 18 to the first locking groove 16. The connecting column 11 is located at the connection of the second slide groove 13 and the first locking groove 16, and the third guide groove 28 is inclined downward from the first locking groove 16 to the second slide groove 13.

[0051] When the shell 1 is disassembled and removed, the elastic member 23 pushes the locking rod 19 to slide toward the push rod 20 through the push ring 27, and the locking rod 19 drives the roller 24 to slide out of the third locking groove 18. When the roller 24 enters the second guide groove 15, the roller 24 abuts against the inclined inner wall of the second guide groove 15, thereby facilitating the locking rod 19 to quickly withdraw from the third locking groove 18 and return to the locking block 342. When the locking rod 19 withdraws from the third locking groove 18, the elastic washer 343 drives the locking block 342 to slide upward through the fastening ring 341, and the locking block 342 slides upward from the second locking groove 17 to the first locking groove 16, and then the fastening ring 341 is rotated. Under the action of the third guide groove 28, the locking block 342 slides from the second locking groove 17 to the second slide groove 13. Under the action of the first guide groove 14, the locking block 342 slides from the second slide groove 13 to the first slide groove 12, and then the fastening ring 341 is slid upward to disassemble and remove the second fastener 34, thereby facilitating the quick disassembly and removal of the signal board 32.

[0052] The implementation principle of Example 2 of the present application is as follows: after the signal board 32 is placed on the first fastener 33, the fastening ring 341 is sleeved on the connecting column 11, and the fastening ring 341 is first slid downward. When the elastic gasket 343 abuts against the signal board 32, the fastening ring 341 is rotated to quickly fix the signal board 32. When the signal board 32 needs to be removed, the fastening ring 341 is first rotated, and then the fastening ring 341 is slid upward to quickly unlock the signal board 32, thereby making the disassembly and assembly of the signal board 32 more convenient and quick.

[0053] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.
