However, due to the consistency problem of tooling, products of different specifications are prone to poor positioning accuracy, and the high cost of tooling processing will greatly increase the cost of product production.

[0003] In view of this, the applicant filed this application after studying the existing technology. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantages of the implementation mode of the utility model clearer, the technical scheme in the implementation mode of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation mode of the utility model. Obviously, the described implementation mode is a part of the implementation mode of the utility model, not all of the implementation modes. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the implementation mode of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected implementation mode of the utility model. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Depend on Figures 1 to 3As shown, an embodiment of the utility model provides a positioning mechanism, including a workbench 1 and a product tooling 2 and a product 3 located on the workbench 1, and also including a driving member 4, a first positioning assembly 5, a second positioning assembly 6 and a guiding assembly 7; the driving member 4 and the first positioning assembly 5 are arranged below the workbench 1, the input end of the first positioning assembly 5 is connected to the output end of the driving member 4, and the output end of the first positioning assembly 5 is driven by the driving member 4 to pass through the workbench 1 and approach or move away from the product tooling 2 for positioning; the second positioning assembly 6 is symmetrically arranged on both sides of the workbench 1, and the guiding assembly 7 is connected and arranged between the output end of the driving member 4 and the input end of the second positioning assembly 6, and the second positioning assembly 6 is guided by the guiding assembly 7 so that the output end of the second positioning assembly 6 moves from both sides of the workbench 1 to approach or move away from the product 3 for positioning. The positioning mechanism of the present application uses the driving member 4 to drive the first positioning component 5 to position the product tooling 2, and uses the second positioning component 6 which is also driven by the driving member 4 to position the product 3, so that the product tooling 2 and the product 3 are positioned synchronously. Since the positioning of the product 3 is completed by the second positioning component 6, there is no need to accurately set the pins of the corresponding specifications of the product 3 on the product tooling 2. A set of product tooling 2 can correspond to more products 3 of different specifications, which is particularly suitable for magnetic circuit positioning, greatly reducing the cost during the production process.

[0022] The workbench 1 is a tabletop suitable for placing product tooling 2, and the lateral mobility of the product tooling 2 is restricted so as to better position it. The workbench 1 may also be provided with a transmission mechanism to facilitate use in the next process.

[0023] It can be known that the driving member 4 in the present application is a driving cylinder 8 vertically arranged below the workbench 1, and a connecting plate 9 is installed at the end of the driving rod as an output end to facilitate the connection of the first positioning component 5 and the guide component 7.

[0024] Preferably, the first positioning assembly 5 includes a positioning pin 10, the end of which is installed on the output end of the driving member 4. A through hole 11 suitable for the positioning pin 10 to pass through is provided on the workbench 1, and a pin hole 12 suitable for the positioning pin 10 to be inserted is provided at the bottom end of the product tooling 2. The positioning pin 10 is driven by the driving member 4 to reciprocate up and down, thereby passing through the pin hole 12 on the workbench 1 and extending into the pin hole 12 at the bottom of the product tooling 2, thereby completing the positioning of the product tooling 2, and then ensuring that when the product 3 is positioned, the position of the product tooling 2 can match and correspond.

[0025] Furthermore, two positioning pins 10 are provided, and positioning the product tooling 2 by using the two positioning pins 10 can better ensure the positioning accuracy of the product tooling 2 .

[0026] A tooling protection block 13 is provided on the workbench 1, and one side end of the tooling protection block 13 extends above the tooling. There are two tooling protection blocks 13, which are symmetrically arranged on the workbench 1. By arranging the tooling protection block 13 above the product tooling 2, it can be prevented that when the positioning pin 10 rises, the product tooling 2 is lifted up and flew away and damaged when it is not accurately inserted into the pin hole 12.

[0027] Preferably, the second positioning assembly 6 includes two sets of slide rails 14, two sets of sliders 15 and two product positioning blocks 16. The two sets of slide rails 14 are symmetrically arranged on both sides of the workbench 1. The sliders 15 are connected to the slide rails 14. The product positioning blocks 16 are installed on the upper ends of the sliders 15. The ends of the product positioning blocks 16 face the product 3 located above the workbench 1. The second positioning assembly 6 reciprocates on the slide rails 14 perpendicular to the workbench 1 through the sliders 15, so that the product positioning blocks 16 on both sides are simultaneously close to or away from the product 3 at the center position, so as to realize the positioning of the product 3. Furthermore, only the product positioning blocks 16 installed on the sliders 15 need to be replaced to be applicable to more product jigs 2, which is very convenient, and there is no need to process and configure the entire product jig 2, which greatly reduces the production cost.

[0028] Preferably, the guide assembly 7 includes two groups of connection blocks 17, two groups of guide blocks 18 and two followers 19. The connection blocks 17 are symmetrically mounted on the output end of the driving member 4, and the guide blocks 18 are fixedly mounted on the connection blocks 17. A guide rail 20 is arranged on the guide block 18, and one end of the follower 19 is fixedly connected to the slider 15, and the other end is adapted to extend into the guide rail 20. Driven by the driving member 4, the connection block 17 drives the guide block 18 to rise or fall, and at this time, the follower 19 located in the guide rail 20 will receive the limit guide of the guide rail 20, and then when the follower moves along the guide rail 20, it drives the slider 15 to move left and right, thereby converting the up and down reciprocating motion of the guide block 18 into the left and right reciprocating motion of the slider 15, and then driving the positioning block of the product 3 for positioning.

[0029] Furthermore, a bearing member 21 is provided at one end of the follower 19 located in the guide rail 20, and the bearing member 21 is rollingly connected to the guide rail 20. By providing the bearing member 21 on the follower 19, the follower 19 can move more smoothly relative to the guide rail 20, so that the guide block 18 drives the slider 15 to move more smoothly.

[0030] As an implementation method, both sides of the workbench 1 can extend outwards partially, and then the guide block 18 passes through this part, so that the guide block 18 is limited in the radial direction, so that it is more stable when performing reciprocating motion in the axial direction.

[0031] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
