[0030] refer to Figures 1-5 This utility model provides a positioning fixture, which includes a fixture body 1, a positioning block 2, and a buffer assembly 3. The fixture body 1 includes a top plate 11, a bottom plate 12, two side plates 13, and a connecting plate 14. The side plates 13 are disposed between the top plate 11 and the bottom plate 12, and the two side plates 13 are respectively disposed at both ends of the top plate 11. The top plate 11, the bottom plate 12, and the side plates 13 form a cuboid shape. The connecting plate 14 is disposed on the bottom surface of the top plate 11. The fixture body 1 has a first through hole 15, which passes through the top plate 11 and the connecting plate 14. The positioning block 2 is disposed on the top surface of the fixture body 1. The positioning block 2 and the five-position positioning block 1 are connected to the top plate 11 and the connecting plate 14. The hardware product is designed to mimic its shape, and the positioning block 2 is used to place the hardware product. The buffer assembly 3 is set on the main body 1 of the fixture. The buffer assembly 3 includes a guide sleeve 31, a guide post 32 and a spring. Part of the guide sleeve 31 is fixedly set in the first through hole 15 of the connecting plate 14, and the other part is exposed at the bottom of the connecting plate 14. The guide post 32 is sleeved with the guide sleeve 31. The spring is located in the first through hole 15 of the top plate 11. The spring is sleeved on the outside of the guide post 32, and one end of the spring abuts against the top surface of the guide sleeve 31, and the other end of the spring abuts against the bottom surface of the positioning block 2. The positioning block 2 can drive the guide post 32 to move back and forth along the axial direction of the guide sleeve 31 and compress or release the spring.

[0031] This utility model provides a positioning fixture with a buffer component 3. When the robotic arm presses down to pick up the material, the positioning block 2 moves downward along with the guide post 32, compressing the spring. The spring acts as a buffer, allowing the positioning block 2 to dissipate force along the direction of the applied force, thus protecting the hardware product. By sleeved on the outside of the guide post 32, this application also ensures the stability of the buffer. Therefore, this application can ensure that the hardware product is not damaged and that the positioning fixture remains intact even after multiple failed picking attempts, reducing fixture maintenance costs. In addition, the positioning fixture with the buffer component 3 ensures the stability of picking up the material and improves production efficiency.

[0032] This application is used in injection molding projects that require the implantation of a large number of small hardware products or nuts, ensuring that the hardware products remain intact and are not damaged or scratched, thus enabling the robotic arm to handle materials stably.

[0033] refer to Figures 2-6 The positioning fixture also includes a limiting component 4, which is connected to the fixture body 1 and the positioning block 2 respectively. The limiting component 4 is used to limit the release displacement of the positioning block 2.

[0034] refer to Figures 3-6 The fixture body 1 also includes a limiting hole 16, which is provided through the top plate 11 and the connecting plate 14. The limiting hole 16 and the first through hole 15 are spaced apart. The limiting component 4 includes a connector 41 and a limiting head 42. One end of the connector 41 is fixedly connected to the positioning block 2, and the other end of the connector 41 passes through the limiting hole 16 and is connected to the limiting head 42. The limiting head 42 is provided on the bottom surface of the connecting plate 14. The connector 41 can reciprocate along the axial direction of the limiting hole 16. The limiting head 42 is used to limit the release displacement of the positioning block 2.

[0035] In the initial state, there is a gap between the limiting head 42 and the connecting plate 14. When the robot presses down on the positioning block 2, it drives the connecting piece 41 and the limiting head 42 to move downward. When the robot disengages from the positioning block 2, the positioning block 2 moves upward due to the elastic force. By setting the limiting component 4, it can prevent the positioning block 2 from flying out of the fixture body 1 due to the elasticity of the spring, thus limiting the position of the positioning block 2.

[0036] Specifically, the limiting component 4 is a limiting pin, and both the limiting head 42 and the connecting piece 41 are cylindrical, with the diameter of the limiting head 42 being larger than the diameter of the connecting piece 41.

[0037] Specifically, there are multiple limiting components 4. In this embodiment, each positioning block 2 is connected to two limiting components 4.

[0038] refer to Figure 3 and Figure 4 The top surface of the top plate 11 of the fixture body 1 is provided with a mounting groove 17, the positioning block 2 is disposed in the mounting groove 17, and the first through hole 15 is located in the mounting groove 17. In the initial state, there is a gap between the bottom surface of the positioning block 2 and the bottom wall of the mounting groove 17, so that there is space for the spring to be compressed, thereby providing a buffering effect for the positioning block 2.

[0039] Specifically, the mounting slot 17 matches the positioning block 2.

[0040] refer to Figure 3 The positioning block 2 has a second through hole 21, which passes through the positioning block 2. The second through hole 21 is connected to the first through hole 15, and the first through hole 15 and the second through hole 21 are coaxially arranged. The guide post 32 is fixedly arranged in the second through hole 21.

[0041] refer to Figure 3 The bottom surface of the base plate 12 is provided with a clearance hole 18 to avoid the guide post 32.

[0042] refer to Figure 1 There are multiple positioning blocks 2, which are spaced apart on the top surface of the fixture body 1.

[0043] In this embodiment, there are four positioning blocks 2, which are arranged in an array. Correspondingly, there are also four mounting slots 17.

[0044] refer to Figure 1 The fixture body 1 has multiple first through holes 15, and multiple buffer components 3 are respectively disposed in the first through holes 15. Correspondingly, the number of second through holes 21 is the same as that of the first through holes 15, and the number of second through holes 21 is also multiple.

[0045] In this embodiment, there are four first through holes and four second through holes, and four buffer components.
