[0087] At present, during the inspection process of workpieces, it is often necessary to change multiple fixtures to fix the workpieces so that the workpieces have different spatial positions during inspection. Operators need to repeatedly install and disassemble the workpieces, which reduces the inspection efficiency.

[0088] In view of this, an embodiment of the present application provides a detection fixture for adjusting the spatial position of a workpiece, so as to reduce the number of times an operator installs and removes the workpiece and improve detection efficiency.

[0091] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0092] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the detection fixture 100 includes a mounting frame 10 , a dividing plate 20 , a flip member 30 , a rotating member 40 , a fixing assembly 50 , a positioning assembly 60 and a clamping assembly 70 .

[0093] The mounting frame 10 has a work surface 111, and the indexing plate 20 is vertically connected to the work surface 111. The flip member 30 is hingedly arranged on the mounting frame 10, and the flip angle can be adjusted relative to the mounting frame 10. The indexing plate 20 is used to display the flip angle of the flip member 30, and the rotation center line of the flip member 30 is perpendicular to the indexing plate 20. The flip member 30 includes a mounting surface 31, and the mounting surface 31 is arranged at a certain angle with the work surface 111. As the flip member 30 rotates relative to the mounting frame 10, the angle between the mounting surface 31 and the work surface 111 also changes accordingly. The fixing component 50 is arranged on the flip member 30 and connected to the indexing plate 20 to fix the flip member 30 relative to the indexing plate 20. In this way, after the flip member 30 rotates a certain angle, it can be fixed relative to the indexing plate 20, so that the angle between the mounting surface 31 and the work surface 111 is maintained at a certain angle. The rotating member 40 is disposed on the mounting surface 31 and is rotatably connected to the flip member 30. The rotation centerline of the rotating member 40 is perpendicular to the mounting surface 31. The rotating member 40 has a connecting surface 41, which is located on the side of the rotating member 40 facing away from the flip member 30. The positioning assembly 60 is disposed on the flip member 30. The positioning assembly 60 is used to connect the rotating member 40 to fix the rotating member 40 relative to the flip member 30, so that after the rotating member 40 rotates a certain angle, the rotating member 40 is fixed relative to the flip member 30, thereby limiting the rotation of the rotating member 40. The clamping assembly 70 is disposed on the connecting surface 41, and is used to detachably fix the workpiece 200 to the rotating member 40.

[0094] In this detection fixture 100, the clamping assembly 70 can detachably fix the workpiece 200 to the rotating member 40, so that the workpiece 200 can rotate in two directions following the flip member 30 and the rotating member 40. The operator can adjust the spatial position of the workpiece 200 by adjusting the position state of the flip member 30 and the rotating member 40 as needed; the fixing assembly 50 can fix the flip member 30 relative to the dividing plate 20 after the flip member 30 rotates a certain angle, and the positioning assembly 60 can fix the rotating member 40 relative to the flip member 30 after the rotating member 40 rotates a certain angle, thereby reducing the possibility of movement of the workpiece 200 during the detection process, so as to facilitate the external detection device to detect the workpiece 200; in this way, without changing the fixture, the detection device can detect different positions of the workpiece 200, which is beneficial to reduce the number of operations for the operator to disassemble and assemble the workpiece 200 and improve the detection efficiency.

[0095] In one embodiment, if Figure 1 As shown, the mounting frame 10 includes a base 11 and a support leg 12, the flip member 30 is hinged to the base 11, a work surface 111 is formed on the upper surface of the base 11, and the support leg 12 is provided on the lower surface of the base 11. By providing the support leg 12, it is helpful to support the base 11 at a height suitable for operation.

[0096] In one embodiment, if Figure 3 and Figure 4 As shown, the fixing assembly 50 includes a positioning pin 51, which is slidably connected to the flip member 30. The indexing plate 20 is provided with at least two positioning holes 21, and the positioning pin 51 is used to be inserted into the positioning holes 21 to fix the flip member 30 relative to the indexing plate 20. In this way, the indexing plate 20 and the flip member 30 can be fixed to each other by the cooperation of the positioning pin 51 and the positioning hole 21, which has a simple structure and is easy to operate.

[0097] In one embodiment, if Figure 1 As shown, the indexing plate 20 is set to be semicircular, and the semicircular surface of the indexing plate 20 is provided with angle scale lines, the 0° scale line coincides with the work surface 111, and the rotation center line of the flip member 30 passes through the center of the indexing plate 20. In this way, by reading the value displayed by the angle scale line, the angle between the mounting surface 31 and the work surface 111 can be known.

[0098] In one embodiment, if Figure 1 As shown, the positioning hole 21 is provided on the arc surface of the dividing plate 20 , and the positioning pin 51 is located above the positioning hole 21 , so that the positioning pin 51 is conveniently connected to the positioning hole 21 , which is conducive to simplifying the structure.

[0099] In one embodiment, if Figure 3 and Figure 4As shown, the fixing assembly 50 further includes a limiting rod 52 and a mounting member 53. The mounting member 53 is disposed on the flip member 30, and the mounting member 53 has a mounting hole 531, a limiting groove 532 and a slide groove 533 that are interconnected, the extension direction of the slide groove 533 is the same as the extension direction of the mounting hole 531, and the extension direction of the limiting groove 532 is perpendicular to the extension direction of the slide groove 533. The limiting rod 52 is vertically connected to the positioning pin 51, the positioning pin 51 is slidably disposed in the mounting hole 531, the limiting rod 52 is slidably disposed in the slide groove 533, the positioning pin 51 is used to move along the mounting hole 531 to fall into or exit the positioning hole 21, and during the movement of the positioning pin 51, the limiting rod 52 moves along the slide groove 533 driven by the positioning pin 51. The distance from the limit groove 532 to the positioning hole 21 is greater than the distance from the limit rod 52 to the end of the positioning pin 51 facing the positioning hole 21, so that when the limit rod 52 is transferred from the slide groove 533 into the limit groove 532, the positioning pin 51 is separated from the positioning hole 21, and the limit groove 532 limits the movement of the positioning pin 51 toward the positioning hole 21 by limiting the movement of the limit rod 52.

[0100] In the above embodiment, the limit rod 52 can be grasped by the operator to facilitate the operator to change the position of the positioning pin 51; through the cooperation between the limit rod 52 and the limit groove 532, the position of the positioning pin 51 can be limited, thereby reducing the possibility that the positioning pin 51 moves toward the dividing plate 20 due to external disturbance during the rotation of the flip member 30, thereby hindering the movement of the flip member 30, which is beneficial to improving the operator's operation fluency and improving the operating experience.

[0101] In one embodiment, if Figure 3 As shown, the fixing assembly 50 further includes a first elastic member 54, the first elastic member 54 connects the positioning pin 51 and the mounting member 53, and the first elastic member 54 is used to generate an elastic force acting on the positioning pin 51, and the elastic force is used to maintain the positioning pin 51 in the positioning hole 21. Maintaining the positioning pin 51 in the positioning hole 21 by the first elastic member 54 is conducive to improving the stability of the relative fixation of the indexing plate 20 and the flip member 30, so that the detection device can detect the workpiece 200.

[0102] In some embodiments, the first elastic member 54 can be selected from various types of springs and elastic elements made of silicone or rubber. Figure 3 As shown, the first elastic member 54 is configured as a spring.

[0103] In one embodiment, the indexing plate 20 is provided with at least two limiting holes, the limiting holes are located on the surface of the indexing plate 20 facing the flip member 30, the fixing assembly 50 includes a convex portion, the convex portion is convexly provided on the surface of the flip member 30 facing the indexing plate 20, and the surrounding wall of the convex portion and / or the limiting hole is elastic, so that the convex portion can enter or exit the limiting hole. The position of the flip member 30 is limited by the cooperation of the convex portion and the limiting hole, the structure is simple, easy to manufacture, and is conducive to saving production costs.

[0104] In one embodiment, if Figure 3 As shown, the fixing assembly 50 includes a first bolt 55, and the first bolt 55 includes a bolt rod 551 and a bolt cap 552. The indexing plate 20 is provided with a guide groove 22, and the guide groove 22 extends in an arc shape. The bolt rod 551 is inserted into the guide groove 22 and is threadedly connected with the flip member 30. The bolt cap 552 is located on the side of the indexing plate 20 away from the flip member 30. The first bolt 55 is used to move toward the flip member 30 so that the bolt cap 552 presses the indexing plate 20, thereby limiting the rotation of the flip member 30 relative to the indexing plate 20. By pressing the bolt cap 552 of the first bolt 55 against the indexing plate 20, the possibility of the flip member 30 moving relative to the indexing plate 20 is reduced, so that the detection device can detect the workpiece 200. In addition, the guide groove 22 can guide the movement of the flip member 30 by cooperating with the first bolt 55, so that the rotation process of the flip member 30 is more stable.

[0105] In one embodiment, if Figure 2 , Figure 5 and Figure 6 As shown, the positioning assembly 60 includes a positioning bead 61 and a second elastic member 62. The second elastic member 62 is arranged on the mounting surface 31 of the flip member 30. The positioning bead 61 is connected to the second elastic member 62. The second elastic member 62 is used to generate an elastic force acting on the positioning bead 61 so that the positioning bead 61 presses the rotating member 40. A positioning groove 42 is provided on the surface of the rotating member 40 facing the flip member 30. The positioning bead 61 can enter or exit the positioning groove 42 through the rotation of the rotating member 40. When the positioning bead 61 is located in the positioning groove 42, the elastic force generated by the second elastic member 62 maintains the positioning bead 61 in the positioning groove 42, thereby limiting the rotation of the rotating member 40 relative to the flip member 30. The mutual fixation of the flip member 30 and the rotating member 40 can be achieved by the second elastic member 62 pushing the positioning bead 61 to cooperate with the positioning groove 42. The positioning bead 61 can exit from the positioning groove 42 through the deformation of the second elastic member 62. The structure is simple and easy to operate.

At least a portion of the positioning bead 61 is disposed in the guide hole 631 and is used to slide along the guide hole 631. By disposing at least a portion of the second elastic member 62 and the positioning bead 61 in the guide hole 631, the movement direction of the positioning bead 61 can be guided, and the possibility of the positioning bead 61 being deviated along the surface of the rotating member 40 due to gravity or friction of the rotating member 40 is reduced, thereby reducing the possibility of the positioning bead 61 and the positioning groove 42 failing to form a match at the correct position, so that the rotating member 40 can be fixed to the flip member 30 after rotating at a preset angle, so as to facilitate the detection of the workpiece 200.

The third elastic member 73 connects the fixing member 71 and the handle 74 to maintain the contact surface 741 in contact with the fixing member 71. The contact surface 741 has a first contact area 7411 and a second contact area 7412, and the distance from the first contact area 7411 to the rotation center of the handle 74 is smaller than the distance from the second contact area 7412 to the rotation center of the handle 74. The handle 74 can be switched between the first state and the second state by rotating, and drive the pushing member 72 to slide. When the handle 74 is in the first state (such as Figure 8 ), the first contact area 7411 contacts the fixing member 71, the pushing member 72 can clamp the workpiece 200 together with the limiting member 75, and when the handle 74 is in the second state (as shown in FIG. Fig. 9 As shown in FIG. 4 , the second contact area 7412 contacts the fixing member 71, and the pushing member 72 separates from the workpiece 200 to release the clamping of the workpiece 200. In this way, the pushing member 72 can be driven to move by rotating the handle 74 to clamp or release the workpiece 200, thereby achieving the fixing and release of the workpiece 200 relative to the rotating member 40. The structure is simple, the operation is convenient, the work is reliable, and the efficiency of installing and removing the workpiece 200 is improved.

The limiting pins 751 are simple in structure and easy to obtain, which is conducive to reducing production costs.

[0114] In one embodiment, if Figure 8 As shown, the clamping assembly 70 includes a support block 76, which is disposed on the rotating member 40 and is used to penetrate the workpiece 200 to support the workpiece 200. This is beneficial to improve the stability of the workpiece 200, so that the detection device can detect the workpiece 200.

[0115] In one embodiment, if Figure 8 and Fig. 9 As shown, the clamping assembly 70 includes a clamping member 77, the clamping member 77 is rotatably connected to the rotating member 40, the clamping member 77 and the rotating member 40 are spaced apart, and the gap between the clamping member 77 and the rotating member 40 is used to accommodate the workpiece 200. The clamping member 77 is used to press the workpiece 200, so that the clamping member 77 can clamp the workpiece 200 together with the rotating member 40. Specifically, the clamping member 77 is used to switch between the third state and the fourth state through rotational motion. When the clamping member 77 is in the third state (such as Figure 8 As shown), the clamping member 77 presses the workpiece 200, so that the clamping member 77 can clamp the workpiece 200 together with the rotating member 40. When the clamping member 77 is in the fourth state (as shown Fig. 9 As shown in FIG. 1 , the clamping member 77 is separated from the workpiece 200. The clamping member 77 and the rotating member 40 are used to clamp the workpiece 200 together, which is beneficial to improve the stability of the workpiece 200, so that the detection device can detect the workpiece 200.

[0116] In one embodiment, the detection fixture 100 further includes a bearing, and the rotating member 40 is connected to the flip member 30 via the bearing, which is beneficial to improve the smoothness of the rotation of the rotating member 40 and improve the user experience.
