Description

Technical Field

[0001] This utility model relates to the field of product positioning technology, and in particular to a flexible positioning mechanism. Background Technology

[0002] A flexible positioning mechanism is a support device for product positioning. Its function is to perform secondary positioning of the product before assembly, ensuring the accuracy of the subsequent pressing position and facilitating better product positioning. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of flexible positioning mechanisms.

[0003] Existing positioning mechanisms have certain drawbacks. First, they cannot effectively achieve flexible control of product positioning, and may cause damage to the product during positioning, which is not conducive to user experience. Second, existing positioning mechanisms do not use mechanical unlocking, which is cumbersome and has a negative impact on actual use. Therefore, we propose a flexible positioning mechanism. Utility Model Content

[0004] Technical problem solved: To address the shortcomings of existing technologies, this utility model provides a flexible positioning mechanism composed of two independent positioning mechanisms. Depending on the type and quantity of products being manufactured, the positioning mechanisms can be controlled individually or simultaneously to complete the positioning function, achieving flexible control of product positioning. The product undergoes a pre-pressure function before positioning to prevent movement during production. Product positioning is achieved by a spring pushing a positioning plate to move the product positioning feature. The spring's thrust can be controlled by adjusting the position of the limit screw, effectively solving the problems in the prior art.

[0009] Preferably, the product pressure plate in the Z direction first uses the force of the positioning plate spring to pre-press the product. The spring force is relatively small to avoid damage to the product. Then, the four reset cylinders on both sides of the product pressure plate are de-pressed, and the product is repositioned by the thrust of the positioning plate spring. The thrust of the positioning plate spring can be adjusted by adjusting the position of the limit screw.

[0010] Preferably, the positioning mechanism body is fixed to the mechanical unlocking bracket by bolts, the mechanical unlocking bracket is fixed to the bearing bracket by bolts, and a rectangular spring is provided between the mechanical unlocking bracket and the bearing bracket.

[0021] like Figure 1-5 As shown, a flexible positioning mechanism includes a lower fixing member 2, a support shaft 1 fixedly mounted on the upper end of the lower fixing member 2, an upper fixing member 3 fixedly mounted on the top of the support shaft 1, a fixing seat 4 mounted on the inner side of the upper fixing member 3, a Z-axis slide cylinder 5 fixedly mounted on the inner side of the fixing seat 4, a connecting seat 6 provided at the bottom of the Z-axis slide cylinder 5, and a positioning mechanism body 7 mounted at the bottom of the connecting seat 6. The positioning mechanism body 7 includes a product pressure plate 9 and a product positioning plate 8, a positioning plate spring 10 installed between the product pressure plate 9 and the product positioning plate 8, and a limit screw 15 installed at the end of the positioning plate spring 10. Two sets of reset cylinders 12 are installed on both outer sides of the product pressure plate 9. A pressure plate assembly 17 is installed at the bottom of the product pressure plate 9. A pressure plate spring 16 is connected between the product pressure plate 9 and the pressure plate assembly 17. It consists of two independent positioning mechanisms. According to the type and quantity of the products being produced, the positioning mechanism can be controlled to complete the positioning function individually or simultaneously, realizing flexible control of the product positioning function. The product has a pre-pressing function before positioning, which can prevent the product from moving during the production process. The product positioning is achieved by the spring pushing the positioning plate to push the product positioning feature. The spring force can be controlled by adjusting the position of the limit screw.

[0022] Furthermore, X-axis adjusting components 11 are installed on both sides of the upper end of the product pressure plate 9, and mechanical unlocking brackets 13 are fixed on the inner sides of both ends of the product pressure plate 9. A bearing bracket 18 is installed at the bottom of the mechanical unlocking bracket 13, and an unlocking bearing 14 is movably installed at the end of the bearing bracket 18.

[0023] Furthermore, the upper fixing member 3 and the lower fixing member 2 are supported by a support shaft 1, and the support shaft 1 is fixed to both the lower fixing member 2 and the upper fixing member 3 by bolts.

[0024] Furthermore, the upper fixing member 3 is fixed to the Z-axis slide cylinder 5 through the fixing bracket 4. The Z-axis slide cylinder 5 drives the connecting seat 6 to move up and down, and the connecting seat 6 drives the positioning mechanism body 7 to move up and down.

[0025] Furthermore, the product pressure plate 9 in the Z direction first uses the force of the positioning plate spring 10 to pre-press the product. The spring force is relatively small to avoid damage to the product. Then, the four reset cylinders 12 on both sides of the product pressure plate 9 are de-pressed, and the product is repositioned by the thrust of the positioning plate spring 10. The thrust of the positioning plate spring 10 can be adjusted by adjusting the position of the limit screw 15.

[0026] Furthermore, the positioning mechanism body 7 is fixed to the mechanical unlocking bracket 13 by bolts, the mechanical unlocking bracket 13 is fixed to the bearing bracket 18 by bolts, and a rectangular spring is provided between the mechanical unlocking bracket 13 and the bearing bracket 18. The unlocking bearing 14 on the inner side of the bearing bracket 18 presses the internal parts of the tooling and unlocks the mechanic.

[0027] The function of this mechanism is to perform secondary positioning of the product before assembly, ensuring the accuracy of the subsequent press-fitting position.

[0028] This mechanism utilizes four bearings on both sides for mechanical unlocking. Four telescopic cylinders on both sides of the fixture ensure the secondary positioning plate is initially in its starting position. The unlocking cylinders and the secondary positioning plate are designed as separate parts, allowing for secondary positioning of products of varying lengths within the production fixture. During operation, the Z-axis pressure plate pre-presses the product using a relatively small spring force to avoid damage. Then, the four telescopic cylinders on both sides of the fixture are de-aired, and the product is repositioned using the spring's thrust. The spring's thrust can be adjusted by changing the position of the set screw.

[0029] Working principle: This utility model includes a support shaft 1, a lower fixing part 2, an upper fixing part 3, a fixing bracket 4, a Z-axis slide cylinder 5, a connecting seat 6, a positioning mechanism body 7, a product positioning plate 8, a product pressure plate 9, a positioning plate spring 10, an X-axis adjusting part 11, a reset cylinder 12, a mechanical unlocking bracket 13, an unlocking bearing 14, a limit screw 15, a pressure plate spring 16, a pressure plate assembly 17, and a bearing bracket 18. It consists of two independent positioning mechanisms. According to the type and quantity of products being produced, the positioning mechanisms can be controlled to complete the positioning function individually or simultaneously, realizing flexible control of the product positioning function. The product has a pre-pressing function before positioning, which can prevent the product from moving during production. The product positioning is achieved by the spring pushing the positioning plate to push the product positioning feature. The spring force can be controlled by adjusting the position of the limit screw.

[0030] The unlocking mechanism of this device uses a rolling mechanism with four bearings, making it a mechanical unlocking device. This mechanism is adjustable in both the Z and Y directions. The linear bearing fixing plate for unlocking is supported by rectangular springs. This design ensures that the unlocking function will not fail due to differences in the position of the tooling being unlocked, and it is compatible with dimensional differences between tooling components.
