By providing the first elastic member 510, the first elastic member 510 exerts an elastic force on the first sliding rod 314 to force the first sliding rod 314 to slide relative to the base 100, so as to drive the first movable clamping block 312 to approach the first fixed clamping block 311 and elastically clamp two sides of the workpiece along the first direction together.

Specifically, the first sliding rod 314 penetrates through the two vertical plates 120 of the base 100 along the first direction, and the linear bearing 130 is disposed on the vertical plate 120, so as to realize the sliding connection between the first sliding rod 314 and the vertical plate 120. In addition, the first movable clamp block 312 is located at one end of the first sliding rod 314, and extends toward the fixed plate 200 to protrude out of the fixed plate 200, so that a workpiece placed on the fixed plate 200 can be clamped. In addition, the first elastic element 510 is sleeved on the first sliding rod 314, and one end of the first elastic element elastically acts on the linear bearing 130 or directly acts on the vertical plate 120, and the other end of the first elastic element elastically acts on the first sliding rod 314 to force the first sliding rod 314 to move. In addition, the first elastic member 510 is specifically a spring, and the first elastic member 510 and the first movable clamping block 312 are respectively located at two sides of the vertical plate 120. In other embodiments, the first elastic member 510 may also be a tension spring, and in this case, the first elastic member 510 and the first movable clamping block 312 are located on the same side of the vertical plate 120. In addition, the first fixed clamping block 311 plays a role of reference, and the first movable clamping block 312 can be matched with the first fixed clamping block 311 to clamp two side edges of the workpiece along the first direction only by moving towards the first fixed clamping block 311.

In one embodiment, the elastic member 500 includes a second elastic member 520, the second clamping assembly 320 includes a second fixed clamping block 321, a second movable clamping block 322, and a second sliding rod 324, the second fixed clamping block 321 is fixed on one side of the fixed plate 200 along the second direction, the second sliding rod 324 is slidably connected to the base 100 along the second direction, the second movable clamping block 322 is connected to the second sliding rod 324, and the second elastic member 520 can elastically act on the second sliding rod 324, so that the second movable clamping block 322 is close to the second fixed clamping block 321 along the second direction. By providing the second elastic member 520, the second elastic member 520 exerts an elastic force on the second sliding rod 324 to force the second sliding rod 324 to slide relative to the base 100, so as to drive the second movable clamping block 322 to approach the second fixed clamping block 321 and elastically clamp two sides of the workpiece along the second direction together.

Specifically, the second sliding rod 324 penetrates through the vertical plate 120 of the base 100 along the second direction and away from the second fixing clamp 321, and the linear bearing 130 is disposed on the vertical plate 120, so that the sliding connection between the second sliding rod 324 and the vertical plate 120 is realized. In addition, the second movable clamp 322 is located at one end of the second slide bar 324, and extends toward the fixed plate 200 to protrude out of the fixed plate 200, so that the workpiece placed on the fixed plate 200 can be clamped. In addition, the second elastic element 520 is sleeved on the second sliding rod 324, and one end of the second elastic element elastically acts on the linear bearing 130 or directly acts on the vertical plate 120, and the other end of the second elastic element elastically acts on the second sliding rod 324 to force the second sliding rod 324 to move. In addition, the second elastic element 520 is specifically a spring, and the second elastic element 520 and the second movable clamping block 322 are respectively located at two sides of the vertical plate 120. In other embodiments, the second elastic member 520 may also be a tension spring, and in this case, the second elastic member 520 and the second movable clamping block 322 are located on the same side of the vertical plate 120. In addition, the second fixed clamping block 321 plays a role of reference, and the second movable clamping block 322 can be matched with the second fixed clamping block 321 to clamp two side edges of the workpiece along the second direction only by moving towards the second fixed clamping block 321.

Specifically, the first clamping assembly 310 includes a first connecting block 315 connected to the first sliding rod 314, the second clamping assembly 320 includes a second connecting block 325 connected to the second sliding rod 324, and one end of the connecting rod 330 is rotatably connected to the first connecting block 315 and the other end is rotatably connected to the second connecting block 325. The two ends of the connecting rod 330 realize the linkage of the first sliding rod 314 and the second sliding rod 324 through the first connecting block 315 and the second connecting block 325, respectively, thereby constituting the linkage between the first clamping assembly 310 and the second clamping assembly 320.

Further, the first connecting block 315 is disposed on the first sliding rod 314 on a side close to the first fixing clamp 311, and the connecting rod 330 is inclined toward the first fixing clamp 311. Thus, when the first elastic member 510 elastically acts on the first sliding rod 314 to force the first sliding rod 314 to drive the first movable clamping block 312 to approach the first fixed clamping block 311, the first sliding rod 314 drives the connecting rod 330 to move through the first connecting block 315, so that the connecting rod 330 further drives the second sliding rod 324 to move through the second connecting block 325, and thus, in cooperation with the elastic action of the second elastic member 520, the second sliding rod 324 drives the second movable clamping block 322 to approach the second fixed clamping block 321, and thus, the workpiece can be clamped in the first direction and the second direction simultaneously through the linkage action of the first clamping assembly 310 and the second clamping assembly 320. On the contrary, the same technical effects can be achieved by starting from the elastic action of the second elastic member 520.

In addition, when a pushing force capable of overcoming the elastic force of the first elastic member 510 is applied to the first clamping assembly 310, the first sliding rod 314 drives the first movable clamping block 312 to be away from the first fixed clamping block 311, the first sliding rod 314 pushes the connecting rod 330 to move through the first connecting block 315, so that the connecting rod 330 further pushes the second connecting block 325 and the second sliding rod 324 to overcome the elastic force of the second elastic member 520, and further, the second sliding rod 324 drives the second movable clamping block 322 to be away from the second fixed clamping block 321.

In one of the embodiments, the position of the first connection block 315 on the first slide bar 314 is adjustable along the first direction. In the second direction, the position of the second connecting block 325 on the second slide bar 324 is adjustable. By changing the positions of the first connecting block 315 and the second connecting block 325, the connecting state of the connecting rod 330 can be changed, and the strength of the linkage between the first clamping assembly 310 and the second clamping assembly 320 can be adjusted. It should be noted that in other embodiments, only one of the first connection block 315 and the second connection block 325 may be made adjustable.

Specifically, the first connecting block 315 is tightly held to the first sliding rod 314, and the strength of the first connecting block 315 tightly holding to the first sliding rod 314 can be adjusted by loosening or screwing the adjusting screw. When the adjusting screw is unscrewed, the force of the first connecting block 315 holding the first sliding rod 314 is the smallest, and the first connecting block 315 can be moved along the axial direction of the first sliding rod 314, thereby realizing the change of the position of the first connecting block 315 on the first sliding rod 314. Further, the first elastic member 510 abuts against the first connection block 315 to indirectly act on the first slide bar 314 through the first connection block 315. The position of the first connecting block 315 on the first sliding rod 314 is changed to adjust the elastic force of the first elastic member 510, so as to adjust the clamping force of the first movable clamping block 312 and the first fixed clamping block 311 on the workpiece, so as to meet the clamping requirements of workpieces with different sizes.

The second connecting block 325 is tightly held on the second sliding rod 324, and the force for tightly holding the second sliding rod 324 by the second connecting block 325 can be adjusted by loosening or screwing the adjusting screw. When the adjusting screw is unscrewed, the force of the second connecting block 325 holding the second slide bar 324 is the smallest, and the second connecting block 325 can be moved along the axial direction of the second slide bar 324, so that the position of the second connecting block 325 on the second slide bar 324 can be changed. Further, the second elastic member 520 abuts against the second connecting block 325 to indirectly act on the second slide bar 324 through the second connecting block 325. The position of the second connecting block 325 on the second sliding rod 324 is changed, so that the elastic force of the second elastic member 520 can be adjusted, and the purpose of adjusting the clamping force of the second movable clamping block 322 and the second fixed clamping block 321 on the workpiece is achieved, so as to meet the clamping requirements of workpieces with different sizes.

Furthermore, by adjusting the first connecting block 315 and the second connecting block 325 at the same time, the clamping acting force in the first direction can be matched with the clamping acting force in the second direction, so as to achieve a better clamping and positioning effect.

Specifically, the number of the first fixing clip blocks 311 is two, and the two first fixing clip blocks 311 are arranged at intervals in the second direction. The two first fixed clamping blocks 311 cooperate to form a datum surface, thereby forming a datum along the first direction when the workpiece is placed on the fixed plate 200. The number of the first fixing clip blocks 311 is two, and the two second fixing clip blocks 321 are spaced apart in the first direction. The two second fixing blocks 321 cooperate to form a reference surface, thereby constituting a reference in the second direction when the workpiece is placed on the fixing plate 200.

Specifically, the first clamping assembly 310 includes a first connecting plate 316, two first sliding rods 314, two first movable clamping blocks 312 and two first elastic members 510, the first connecting plate 316 connects the two first sliding rods 314, the two first movable clamping blocks 312 are disposed on the first connecting plate 316 at intervals along the second direction, and the two first sliding rods 314 are both sleeved with the first elastic members 510. Through the arrangement of the two first sliding rods 314, the two first movable clamping blocks 312 are driven to move stably, so that the workpiece is clamped stably, and the stability of positioning and clamping is improved.

The second clamping assembly 320 includes a second connecting plate 326, two second sliding rods 324, two second movable clamping blocks 322, and two second elastic members 520, the second connecting plate 326 connects the two second sliding rods 324, the two second movable clamping blocks 322 are disposed on the second connecting plate 326 at intervals along the first direction, the two second sliding rods 324 are respectively sleeved with one second elastic member 520, and the second connecting block 325 connects the two second sliding rods 324. Through the arrangement of the two second sliding rods 324, the two second movable clamping blocks 322 are driven to move stably, so that the workpiece is clamped stably, and the stability of positioning and clamping is improved.

In one embodiment, the first clamping assembly 310 includes a thrust rod 317, and the thrust rod 317 is disposed at an end of the first sliding rod 314 away from the first movable clamping block 312. Thus, by applying a pushing force to the pushing rod 317, the first sliding rod 314 can be pushed to drive the first movable clamping block 312 to be away from the first fixed clamping block 311, so as to release the workpiece along the first direction, and in addition, the movement of the first sliding rod 314 can drive the connecting rod 330 to move, so as to push the second sliding rod 324 to drive the second movable clamping block 322 to be away from the second fixed clamping block 321, so as to release the workpiece along the second direction, so as to enable the positioning apparatus 10 to present an open state.

Specifically, in the embodiment where there are two first sliding bars 314, a thrust bar 317 connects the two first sliding bars 314 to make the two first sliding bars 314 slide synchronously with a small thrust.

In one embodiment, the positioning device 10 further includes four positioning pins 400, and the four positioning pins 400 are distributed on the fixing plate 200 in a rectangular shape. The positioning pin 400 can be matched with the positioning hole on the workpiece, thereby realizing accurate positioning on the fixing plate 200.
