Description

Technical Field

[0001] The utility model belongs to the technical field of tooling fixtures, and in particular relates to an electromagnetic compatible tooling fixture. Background Art

[0002] Electromagnetic compatibility refers to the ability of a device or system to operate in compliance with requirements in its electromagnetic environment and not cause intolerable electromagnetic interference to any device in its environment. During the robot detection process, the drive wheel needs to be tested for electromagnetic compatibility and fixed with a fixture during the test.

[0003] In the Chinese patent with publication number CN217860836U, a belt-loaded fixture for electromagnetic compatibility testing of a mobile service robot is mentioned, which includes a front base, a rear base, a lifting platform assembly, a telescopic assembly, a resistance roller, a free roller and a damper. The left and right sides of the front and rear bases are respectively connected by a telescopic assembly, and the telescopic assembly can adjust the distance between the front base and the rear base.

The resistance roller and the free roller are arranged in parallel between the telescopic assemblies on the left and right sides to support the driving wheel of the service robot, and the resistance roller is connected to the damper for loading the driving wheel. However, when the fixture is in use, the base support of the robot is unstable. When in use, it can only support the driven wheel of the robot and cannot fix it, thereby affecting the electromagnetic compatibility test stability of the driving wheel of the robot.

[0004] In addition, although the fixture can be adjusted according to the needs of different robots when in use, the adjustment process is relatively cumbersome, thereby affecting the electromagnetic compatibility test efficiency of the robot's driving wheel. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1 - Figure 4 As shown, an electromagnetic compatibility fixture includes a connecting frame 1, a first through slot 3 and a second through slot 4: there are two first through slots 3 and two second through slots 4, and the two first through slots 3 and the two second through slots 4 are respectively opened around the outer wall of the connecting frame 1, and a limiting device 5 is movably inserted and connected between the first through slots 3 and the second through slots 4. Two mounting blocks 2 are fixedly connected at both ends of the connecting frame 1, a connecting plate 6 is fixedly connected between the two sides of the inner wall of the connecting frame 1, a connecting groove 7 is opened on one side of the top of the connecting plate 6, a stabilizing rod 8 is fixedly connected between the two sides of the inner wall of the connecting groove 7, a sliding block 10 is movably inserted and connected to the outer surface of the stabilizing rod 8, and a supporting mechanism 9 is fixedly connected to the top of the sliding block 10.

[0024] Depend on Figure 1 - Figure 3 It can be seen that the limiting device 5 includes a longitudinal sliding frame 51, a transverse sliding frame 52, a clamping mechanism 53 and a limiting plate 54. There are two longitudinal sliding frames 51 and two transverse sliding frames 52, four clamping mechanisms 53, and the four clamping mechanisms 53 are movably connected to the longitudinal sliding frame 51 and the transverse sliding frame 52. There are eight limiting plates 54, and the eight limiting plates 54 are respectively fixedly connected to the two ends of the longitudinal sliding frame 51 and the two ends of the transverse sliding frame 52. The longitudinal sliding frames 51 are movably connected to the two first through grooves 3, and the transverse sliding frames 52 are movably connected to the two second through grooves 4.

[0025] The clamping mechanism 53 includes a displacement block 531, a fixed plate 532, a movable rod 533, a first spring 534, a clamping plate 535 and a limit block 536. There are two movable rods 533, first springs 534 and limit blocks 536 in total, and the two movable rods 533 are movably connected to both sides of the fixed plate 532. The clamping plate 535 is fixedly connected to one end of the two movable rods 533. The two limit blocks 536 are respectively fixedly connected to the other ends of the two movable rods 533. The two first springs 534 are respectively sleeved on the outer surfaces of the two movable rods 533. The fixed plate 532 is fixedly connected to one side of the top of the displacement block 531. The displacement block 531 is movably connected to the longitudinal sliding frame 51 and the transverse sliding frame 52.

[0026] As can be seen from the above, the device is fixed by four mounting blocks 2, and the limit plate 54 is pulled. The limit plate 54 drives the longitudinal sliding frame 51 or the transverse sliding frame 52 to slide in the first through groove 3 or the second through groove 4. The movement of the longitudinal sliding frame 51 and the transverse sliding frame 52 can drive the clamping mechanism 53 movably connected thereto to be displaced, so that the distance between the four clamping mechanisms 53 can be adjusted, so that the device is suitable for different robot bases, and the driven wheel of the robot is inserted between the fixed plate 532 and the clamping plate 535, and the robot base is pressed down so that the driven wheel of the robot moves downward, so that the driven wheel of the robot squeezes the clamping plate 535, and the clamping plate 535 moves and drives the movable rod 533 fixedly connected thereto to slide in the fixed plate 532, and the movable rod 533 pulls the limit block 536 fixedly connected thereto to move, so that the limit block 536 squeezes the first spring 534, so that the first spring 534 contracts, so that the driven wheel of the robot can be clamped according to its size, thereby improving the stability of the robot fixation and the stability of the electromagnetic compatibility detection of the robot's driving wheel.

[0027] Preferably, the first spring 534 is fixedly connected between the limiting block 536 and the fixing plate 532 , and the bottom end of the clamping plate 535 is in close contact with the top end of the displacement block 531 but not connected.

[0028] As can be seen from the above, the resilience of the first spring 534 is utilized to facilitate the resetting of the clamping plate 535 , and to facilitate the movement of the clamping plate 535 when the clamping plate 535 is not connected to the displacement block 531 .

[0029] Embodiment 2:

[0030] refer to Figure 1 and Figure 4 As shown, the supporting mechanism 9 includes a supporting plate 91, a movable groove 92, a limiting rod 93, a movable frame 94, a second spring 95 and a supporting roller 96. There are two movable grooves 92, limiting rods 93, movable frame 94, second spring 95 and supporting roller 96 in total, and the two movable grooves 92 are respectively opened at one end of the supporting plate 91, the two limiting rods 93 are respectively fixedly connected between the two sides of the inner walls of the two movable grooves 92, the two movable frames 94 are respectively movably connected to the outer surfaces of the two limiting rods 93, the two second springs 95 are respectively sleeved on the outer surfaces of the two limiting rods 93, the two supporting rollers 96 are respectively movably connected to one end of the two movable frames 94, and the support plate 91 is fixedly connected to the sliding block 10.

[0031] As can be seen from the above, by pulling the supporting mechanism 9, the supporting mechanism 9 drives the sliding block 10 to slide on the outer surface of the stabilizing rod 8, so that the position of the supporting mechanism 9 can be adjusted according to the position of the driving wheel. When the robot base and the device are installed, the driving wheel is in close contact with the top outer surfaces of the two supporting rollers 96. The robot base moves downward, so that the driving wheel presses down the supporting rollers 96. The supporting rollers 96 drive the movable frame 94 movably connected to it to slide on the outer surface of the limiting rod 93. When the movable frame 94 moves, it squeezes the second spring 95, causing the second spring 95 to contract, so that the supporting rollers 96 support the driving wheel, which is beneficial to the detection of the driving wheel.

[0032] Preferably, the second spring 95 is fixedly connected between the movable frame 94 and one side of the inner wall of the movable groove 92 .

[0033] As can be seen from the above, the supporting roller 96 can stably support the driving wheel by utilizing the force of the second spring 95 .
