[0025] In addition, the technical features involved in different embodiments of the utility model described below can be combined with each other as long as there is no conflict.

[0026] Please see Figure 1 And Figure 2The utility model discloses a brake device for fixing the carrier plate 103 at the preset position on the sliding rail, and the brake device comprises a clamping mechanism and a power piece 21, the clamping mechanism comprises two oppositely arranged push assembly 1, and the push assembly 1 comprises the brake pad 13 corresponding to the side face of the carrier plate 103, and the power piece 21 drives the synchronous movement of the two oppositely arranged brake pads 13 towards the direction close to or away from the carrier plate 103.

[0027] The carrier plate 103 slides on the sliding rail under the action of inertia, and the oppositely arranged brake pads 13 abut against the side walls of the carrier plate 103 from both sides, and the friction between the brake pads 13 and the carrier plate 103 prevents the carrier plate 103 from continuing to slide. In this braking mode, the friction between the brake pads 13 and the carrier plate 103 gradually increases, so that the sliding speed of the carrier plate 103 gradually decreases, and the process of the carrier plate 103 from sliding to stationary is relatively stable, which helps to reduce the reaction force of the workpiece in the carrier plate 103, and can be suitable for the carrier plate 103 with large mass. Since the two brake pads 13 operate synchronously, it is helpful to keep the carrier plate 103 in the central position, and it is helpful to improve the accuracy of the position of the carrier plate 103.

[0028] Specifically, please refer to the following examples.

[0029] Example 1:

[0030] Please refer to Figure 1 and Figure 2 The brake device shown in a preferred embodiment of the present application is used for fixing the carrier plate 103 at the preset position on the sliding rail. The sliding rail comprises two groups of oppositely arranged support frames 101. The horizontal direction parallel to the support frame 101 is the first direction, and the horizontal direction perpendicular to the first direction is the second direction. The support frame 101 is provided with a plurality of rows of horizontally arranged pulley blocks 102 which are free to rotate towards the first direction. The pulley block 102 is arranged between the support frames 101 and is used for supporting the carrier plate 103. The carrier plate 103 is supported on the pulley and slides along the first direction under the action of inertia. In this embodiment, the carrier plate 103 is configured in the shape of a rectangle, and the total mass of the carrier plate 103 filled with workpieces is about 800 kg.

[0031] The brake device comprises three groups of clamping mechanisms and connecting pieces 2. Each group of clamping mechanisms comprises two push assembly 1s which are axisymmetric along the first direction, and the push assembly 1 comprises the brake pad 13 which is arranged vertically and parallel to the first direction. The connecting piece 2 is connected between the two push assembly 1s in the corresponding clamping mechanism, and is controllably telescopic along the second direction, drives the two brake pads 13 of the corresponding group of clamping mechanisms to move along the second direction close to the side face of the carrier plate 103, so as to clamp the carrier plate 103 and prevent the carrier plate 103 from continuing to slide. When the carrier plate 103 is located at the preset position, the brake pads 13 of the three groups of clamping mechanisms abut against the two side faces of the carrier plate 103 parallel to the first direction.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 , the pushing assembly 1 further comprises a fixing member 11, a pushing arm 12 and a sliding rod 14.

[0033] The fixing member 11 is fixedly connected to the support frame 101 of the sliding rail in the vertical direction, and the thickness of the fixing member 11 in the second direction is large. The lower half of the fixing member 11 is fixedly connected with a rotating frame 111, which extends downward away from the side of the fixing member 11 away from the carrier disc 103. The rotating frame 111 is used to support a rotating shaft 112 parallel to the first direction. The upper half of the fixing member 11 is provided with a sliding passage penetrating through the fixing member 11 in the second direction, and the sliding passage is configured in a rectangular shape.

[0034] The structure of the sliding rod 14 matches the sliding passage and is slidingly connected to the sliding passage. The two ends of the sliding rod 14 are expanded to form limiting portions 141 that cannot pass through the sliding passage, preventing the sliding rod 14 from falling off. The middle of the side of the sliding rod 14 close to the carrier disc 103 is formed with a mounting groove, and the brake pad 13 is mounted in the mounting groove and protrudes from the surface of the sliding rod 14, so that the brake pad 13 away from the side of the carrier disc 103 is completely embedded in the limiting portion 141 of the sliding rod 14, preventing the brake pad 13 from falling off under the action of friction. The brake pad 13 is detachably connected to the sliding rod 14, facilitating the replacement of the brake pad 13.

[0035] The pushing arm 12 has opposite abutting ends 121 and moving ends 122, and a rotating portion 123 disposed between the abutting ends 121 and the moving ends 122. The rotating portion 123 of the pushing arm 12 is rotationally connected to the rotating shaft 112, so that the pushing arm 12 as a whole rotates in the second direction. The abutting end 121 of the pushing arm 12 is offset relative to the moving end 122 towards the direction close to the carrier disc 103, so that the pushing arm 12 as a whole forms an obtuse angle, and the rotating portion 123 is disposed at the turning point of the pushing arm 12. The abutting end 121 of the pushing arm 12 is rotationally connected to a group of rollers 124 arranged in the first direction and freely rotating in the second direction. The position of the roller 124 corresponds to the side of the sliding rod 14 away from the carrier disc 103, and is used to abut the sliding rod 14 to slide in the second direction, so that the brake pad 13 abuts the carrier disc 103. Since the side of the sliding rod 14 away from the carrier disc 103 is a plane, and the roller 124 can freely rotate, the friction between the abutting end 121 of the pushing arm 12 and the sliding rod 14 is small, preventing structural interference caused by the inconsistent movement directions of the two.

[0036] The connecting member 2 is arranged along the second direction, and two ends of the connecting member 2 are rotationally connected to the moving ends 122 of the two push arms 12 of the same set of clamping mechanisms, respectively. The connecting member 2 is controllably telescopic, and drives the brake pad 13 to move synchronously, which helps to clamp the carrier 103 and position the carrier 103 in the middle of the sliding track. In the embodiment, the connecting member 2 comprises a power member 21 and a connecting rod 22 connected to one end of the power member 21, and the power member 21 is an oil cylinder. In other embodiments, the connecting member 2 may, for example, also be a structure in which the same connecting rod 22 is connected to two ends of the power member 21.

[0037] In the embodiment, the push assembly 1 further comprises a spring member 15. The spring member 15 is sleeved on the middle part of the sliding rod 14 and cannot pass through the sliding passage. One end of the spring member 15 abuts against the side of the fixed member 11 away from the carrier 103, and the other end of the spring member 15 abuts against the limiting part 141 of the sliding rod 14. When the brake pad 13 abuts against the carrier 103, the spring member 15 is compressed under force. When the connecting member 2 is retracted to drive the push arms 12 to rotate, so that the abutting ends 121 of the push arms 12 are away from the carrier 103 and no longer apply a pushing force to the sliding rod 14 towards the carrier 103, the spring member 15 restores to push the sliding rod 14 to slide, and drives the brake pad 13 to move away from the carrier 103.

[0038] In the embodiment, the structures of the three sets of clamping mechanisms and the connecting member 2 have slight differences in time and speed of operation, so that the carrier 103 is first decelerated and then completely stopped and positioned in the preset position.

[0039] The utility model discloses the beneficial effect lies in, the carrier 103 of the quality of being convenient for is positioned in the preset position stably and accurately, and the whole structure is simple, and the cost is lower.

[0040] Embodiment two:

[0041] The difference between the embodiment and the embodiment one is that in the embodiment, the multiple sets of clamping mechanisms are connected to the same connecting member 2, the connecting member 2 is horizontally arranged, and is a plate-shaped structure that is controllably telescopic along the second direction under the drive of the oil cylinder.
