Detailed Description

In order to clearly understand the technical features, objects and effects of the present invention, the embodiments of the present invention will be described with reference to the accompanying drawings, in which the same reference numerals in the drawings denote the same or similar components.

"exemplary" means "serving as an example, instance, or illustration" herein, and any illustration, embodiment, or steps described as "exemplary" herein should not be construed as a preferred or advantageous alternative.

In this document, "first", "second", etc. do not mean importance or order thereof, but are used to distinguish one from another so as to facilitate description of the document.

For the sake of simplicity, only the parts relevant to the present invention are schematically shown in the drawings, and they do not represent the actual structure as a product.

Fig. 1 is a perspective view of one illustrative embodiment of a lateral positioning mechanism for circuit breaker testing. As shown in fig. 1, a lateral positioning mechanism 10 for testing a circuit breaker includes a supporting base 11 and two jaw assemblies 12. The two jaw assemblies 12 are oppositely disposed along the first direction D1.

Each jaw assembly 12 includes a base 121 and a tab 122. The base 121 is movably connected to the support base 11 in the first direction D1 to be able to abut against the circuit breaker by movement in a direction parallel to the first direction D1. The base 121 is movably connected to the supporting base 11 by, for example, a linear guide pair, but is not limited thereto. Thereby, the two bases 121 can abut against the circuit breaker in opposite directions to achieve positioning of the circuit breaker in the first direction D1.

Figure 2 is a perspective view of the jaw assembly 12 shown in figure 1. As shown in fig. 2, the flip 122 is rotatably connected to the base 121 about a first axis X1, wherein the first axis X1 is, for example, perpendicular to the first direction D1, but not limited thereto. The flipper 122 can be flipped against the circuit breaker for limiting the circuit breaker movement in a direction perpendicular to the first direction D1. Fig. 3 is a schematic view illustrating an operation state of the jaw assembly shown in fig. 1 for positioning the circuit breaker, in which the jaw assembly on the right side of fig. 1 is shown. Specifically, as shown in fig. 3, in the present exemplary embodiment, after the base 121 moves in the direction opposite to the first direction D1 to the position required for positioning (i.e., the position shown in fig. 3), the turnover 122 can be turned over counterclockwise from the position shown by the solid line to the position shown by the dotted line, and tightly grips the turnover of the circuit breaker 60 in the vertical downward direction, so as to limit the movement of the circuit breaker in the vertical direction (at this time, the lower side of the circuit breaker has a supporting plane for supporting the circuit breaker by default).

The transverse positioning mechanism 10 limits the circuit breaker to a position to be positioned through the movement of the base 121 of the jaw assembly 12, and then turns over and fastens the circuit breaker through the turning buckle 122 of the jaw assembly 12, thereby being beneficial to stably fixing the circuit breaker. Since the base 121 can change its position with respect to the support base 11, the lateral positioning mechanism can be used to fix various types of circuit breakers.

In the present exemplary embodiment, the lateral positioning mechanism 10 is provided with two jaw assemblies 12. Thereby facilitating more stable fixation of the circuit breaker. Without limitation, in other exemplary embodiments, the lateral positioning mechanism 10 may also be provided with only one latch assembly 12, and the latch assembly 12 may cooperate with other structures to fix the position of the circuit breaker along the first direction D1, for example, any structure capable of changing the position relative to the supporting seat 11 along the first direction D1, which is not described herein again.

As shown in fig. 1 and 2, in the illustrated embodiment, each jaw assembly 12 further includes a telescopic cylinder 123. The cylinder body of the telescopic cylinder 123 is rotatably connected with the base 121 and the rotation axis is parallel to the first axis X1, and the piston rod of the telescopic cylinder 123 is rotatably connected with the turnbuckle 122 and the rotation axis is parallel to the first axis X1. Two states of change of the telescopic cylinder 123 during operation are shown in fig. 3. Thereby automatically controlling the flip 122 to flip.

As shown in fig. 2, in the exemplary embodiment, each jaw assembly 12 also includes a bumper 124. The buffer 124 is a conventional buffer, and includes, for example, a telescopic rod and a buffer head, and the buffer head is connected to the telescopic rod. When the buffering head is pressed, the telescopic rod contracts and compresses the spring inside the telescopic rod, so that the buffering effect is achieved. In the present exemplary embodiment, the buffer 124 is disposed on the base 121 and the axial direction of the telescopic rod thereof is parallel to the first direction D1. The position of the bumper 124 is configured such that its bumper head can abut the circuit breaker prior to the base 121 during movement of the jaw assembly 12 toward the circuit breaker. Borrow this to play the cushioning effect, speed when reducing the base contact circuit breaker does benefit to the protection circuit breaker.

As shown in fig. 1, in the illustrated embodiment, the lateral positioning mechanism 10 further includes a first drive mechanism 13 and a second drive mechanism 14. A first drive mechanism 13 is connected to one of the jaw assemblies 12 to urge the jaw assembly 12 connected thereto to move relative to the support base 11. A second drive mechanism 14 is connected to the other of the jaw assemblies 12 to urge the jaw assembly 12 connected thereto to move relative to the support base 11. Therefore, the automatic control of the transverse positioning mechanism is realized, and the fixed position of the circuit breaker is accurately controlled. The first drive mechanism 13 is provided, for example, as a servomotor, which drives the jaw assembly 12 connected thereto, for example, by means of a spindle-nut mechanism. The second drive mechanism 14 is provided as, for example, an air cylinder, and further, as, for example, a rodless air cylinder. Therefore, compared with the method that the servo motor is used completely, the method is favorable for saving the cost on the premise of ensuring the positioning precision.

As shown in fig. 3, in the process that the jaw assembly 12 is driven to move toward the circuit breaker 60, the buffer head of the buffer 124 first abuts against the circuit breaker 60, the jaw assembly 12 continues to move toward the circuit breaker 60, the buffer head of the buffer 124 is pressed, the telescopic rod contracts and performs a buffering function, and after the jaw assembly 12 continues to move toward the circuit breaker 60 to a position required by the positioning, the jaw assembly 12 stops moving. Then, the telescopic cylinder 123 acts to drive the turnbuckle 122 to turn over by about 90 degrees counterclockwise, and tightly buckle the turnbuckle of the circuit breaker 60. Thereby stably fixing the circuit breaker 60 at a position where positioning is required.

Fig. 4 is a schematic top view of one illustrative embodiment of a positioning device for circuit breaker testing. Fig. 5 is a perspective view for explaining the positioning device shown in fig. 4. Referring to fig. 4 and 5, the positioning device includes a base 20, a support member 30, and a lateral positioning mechanism 10 as shown in fig. 1. The supporting member 30 is disposed on the base 20 and is used to support the circuit breaker 60. The supporting seat 11 of the transverse positioning mechanism 10 is fixedly connected with the base 20.

Specifically, in the present exemplary embodiment, the support 30 includes two roller groups 31. Each roller group 31 includes a plurality of rollers arranged along the first direction D1, the axes of the rollers are perpendicular to the first direction D1, and the two roller groups 31 are arranged at intervals along the axial direction of the rollers. Jaw assembly 12 is disposed between two roller sets 31. Therefore, the resistance of the circuit breaker to move along the first direction can be reduced, and the position of the circuit breaker can be conveniently adjusted along the first direction, but the circuit breaker is not limited to the first direction.

In the illustrated embodiment, the positioning device further comprises a first longitudinal abutment 41 and a second longitudinal abutment 51. The first longitudinal abutting member 41 is movably disposed on the base 20 along a second direction D2, and the second direction D2 is perpendicular to the first direction D1. The second longitudinal abutting piece 51 is movably disposed to the base 20 in the second direction D2. The first longitudinal abutting piece 41 and the second longitudinal abutting piece 51 are oppositely disposed in the second direction D2 to be capable of abutting against the circuit breaker 60 in opposite directions. Thereby stably fixing the circuit breaker 60 in the second direction D2.

Specifically, as shown in fig. 4 and 5, in the present exemplary embodiment, the second longitudinal abutting piece 51 has two abutting arms 511 distributed in the first direction D1. The two abutting arms 511 are used for abutting against the circuit breaker 60, and a yielding gap 512 is formed between the two abutting arms 511 and used for accommodating the test function area 61 of the circuit breaker 60. Thereby bypassing the test function zone 61 of the circuit breaker 60 for functional testing.

As shown in fig. 4 and 5, in the exemplary embodiment, the positioning device also includes a third drive mechanism 42 and a fourth drive mechanism 52. The third driving mechanism 42 is connected to the first longitudinal abutment 41 to drive the first longitudinal abutment 41 to move relative to the base 20. The fourth driving mechanism 52 is connected to the second longitudinal abutting member 51 to drive the second longitudinal abutting member 51 to move relative to the base 20. In the exemplary embodiment, the third driving mechanism 42 is, for example, a cylinder, and the first longitudinal abutting member 41 is movably connected to the base 20, for example, by a piston rod of the cylinder, and moves to the circuit breaker 60 under the push of the piston rod of the cylinder, thereby fixing the circuit breaker 60. The fourth driving mechanism 52 is, for example, an air cylinder, the second longitudinal abutting member 51 is movably connected to the base 20, for example, through a linear guide pair, under the pushing of a piston rod of the air cylinder, the two abutting arms 511 of the second longitudinal abutting member 51 move to the circuit breaker 60, and abut against the circuit breaker 60 through the two abutting arms 511, so that the circuit breaker 60 is fixed, and the testing functional area 61 is avoided for performing a subsequent functional test.
