Therefore, the requirements for tooling design are becoming more and more stringent, and appropriate positioning methods play a very important role in current development.

[0003] In existing technologies, positioning devices typically lock the parts after placement and then manually remove them after processing. However, for parts with complex surface shapes, high-precision positioning structures with corresponding shapes are often required. When manually handling the parts, friction increases the difficulty of operation. At the same time, the parts need to be pressed continuously during placement, which does not allow for convenient pre-locking to free the operator's hands. Utility Model Content

Detailed Implementation

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1 Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a special high-precision positioning device, which includes a positioning component 1, a product body 2, and a pre-clamping component 3. By setting the positioning component 1 and the pre-clamping component 3, the product body 2 can be positioned and locked in multiple positions, ensuring the processing stability of the product body 2. Compared with traditional mold positioning, the cost of use is lower, and the contact friction of the product body 2 during disassembly and assembly is smaller. At the same time, with the cooperation of the pre-clamping component 3, the pressed product body 2 can be pre-tightened to prevent it from falling off. There is no need to apply pressure to the product body 2 all the time. This not only frees the operator's hands, but also improves safety and avoids scratches caused by incorrect hand pressing position during locking action.

[0032] Specifically, the positioning component 1 includes a support plate 11, a corner cylinder 12 fixed to the top of the support plate 11, a cylindrical positioning component 13 provided on the top of the support plate 11, a first support block 14 fixed to the top of the support plate 11, and a contour positioning component 15 provided on the top of the support plate 11.

[0033] By setting the cylindrical positioning component 13 and the contour positioning component 15, positioning and energy storage can be performed when the product body 2 is pressed down, so as to automatically support the movement of the product body 2 when it moves up and resets.

[0034] The rotary cylinder 12 is a spiral hydraulic rotary cylinder, model DKX-M-40-900, with a maximum torque of 900 N·m and a rotation angle of 90° / 180° / 270°. In this application, the rotary cylinder 12 is adjusted to a 90° rotation angle setting.

[0035] Specifically, the product body 2 is located on the top of the support plate 11, including a base 21 located above the support plate 11, and a second support block 21-1 is fixed on the base 21.

[0036] Specifically, the pre-clamping component 3 is set on the support plate 11, including a storage sleeve 31 fixed inside the support plate 11, a sliding rod 32 slidably connected inside the storage sleeve 31, and an anti-slip airbag 33 is provided on the top of the sliding rod 32.

[0037] By setting the anti-slip airbag 33, it can make anti-slip contact with the base 21 in the inflated state, increasing the friction force that the base 21 needs to overcome to detach, thus achieving the purpose of pre-tightening and preventing detachment.

[0038] Example 2 Reference Figures 2-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0039] Specifically, the cylindrical positioning component 13 includes a fixed seat 13-1 fixed to the top of the bearing plate 11, an auxiliary block 13-2 fixed to one side of the fixed seat 13-1, and a sliding column 13-3 slidably connected inside the fixed seat 13-1.

[0040] A positioning head 13-4 is fixed to the top of the sliding column 13-3, and a first spring 13-5 is fixed to the bottom of the sliding column 13-3.

[0041] The first support block 14 and the auxiliary block 13-2 are both located at the bottom of the upper pressure plate of the corner cylinder 12. They are used to support the product body 2 and, after the corner cylinder 12 has completed its operation, they work together with the upper pressure plate of the corner cylinder 12 to lock the product body 2.

[0042] The top of the bearing plate 11 has a recessed hole and is slidably connected to the sliding column 13-3. The bottom end of the first spring 13-5 contacts the bottom of the inner cavity of the recessed hole. This design not only meets the installation requirements of the first spring 13-5, but also meets the storage requirements of the sliding column 13-3, ensuring the stability of the sliding column 13-3 in its up and down movement.

[0043] The contour positioning component 15 includes a sleeve 15-1 fixed inside the support plate 11, and a contour positioning head 15-2 is slidably connected inside the sleeve 15-1.

[0044] In practical applications, one end of the contour positioning head 15-2 is fixed with a fourth spring, and the other end of the fourth spring is fixed inside the sleeve 15-1. The fourth spring provides elastic support for the contour positioning head 15-2, so that after the corner cylinder 12 is unlocked, it is convenient to detach the top of the product body 2.

[0045] The bottom of the base 21 has a cylindrical positioning groove 21-2, which is slidably connected to the sliding column 13-3.

[0046] The cylindrical positioning groove 21-2 and the sliding column 13-3 are used to provide positioning support, ensuring the accuracy and stability of the base 21.

[0047] The bottom of the base 21 is provided with a contour positioning groove 21-3. The connection between the first support block 14 and the contour positioning groove 21-3, and the connection between the contour positioning head 15-2 and the contour positioning groove 21-3 are slidably connected.

[0048] With the cooperation of the first support block 14, the contour positioning head 15-2 and the contour positioning groove 21-3, the first support block 14 and the contour positioning head 15-2 can support the two sides of the inner cavity of the contour positioning groove 21-3, thereby helping to improve the placement stability of the base 21.

[0049] The storage sleeve 31 has a storage cavity 31-1 inside, which is slidably connected to the slide rod 32 and sealed. A second spring 34 is fixed inside the storage cavity 31-1, and the other end of the second spring 34 is fixed to the slide rod 32.

[0050] The second spring 34 provides elastic support for the slide bar 32, maintaining the slide bar 32 in a high position without external force.

[0051] A ventilation groove 32-1 is provided at the center of the slide rod 32, an installation groove 32-2 is provided at the top of the slide rod 32, an anti-slip airbag 33 is fixed in the installation groove 32-2, and a damping arc groove 32-3 is provided on the outer surface of the slide rod 32.

[0052] The inner cavity of the anti-slip airbag 33, the inner cavity of the slide bar 32, and the inner cavity of the storage cavity 31-1 are connected in sequence, and the top of the anti-slip airbag 33 protrudes from the mounting groove 32-2.

[0053] By setting up the storage cavity 31-1, the ventilation groove 32-1 and the anti-slip airbag 33, when the slide bar 32 moves downward, the space inside the storage cavity 31-1 decreases, allowing gas to flow into the anti-slip airbag 33 through the ventilation groove 32-1. The anti-slip airbag 33 will then gradually expand and fill the middle position of the contour positioning groove 21-3, effectively increasing the friction between the base 21 and the base 21, and preventing the base 21 from moving upward and detaching from the anti-slip airbag 33.

[0054] The outer ring of the storage sleeve 31 is provided with an anti-slip component 35, including a crossbar 35-1 slidably connected to the storage sleeve 31. One end of the crossbar 35-1 is fixed with a damping ball head 35-2 and slidably connected to the damping arc groove 32-3.

[0055] A third spring 35-3 is fitted on the crossbar 35-1. One end of the third spring 35-3 is fixed to the crossbar 35-1, and the other end of the third spring 35-3 is fixed to the outer ring of the storage sleeve 31.

[0056] The diameter of the damping ball head 35-2 is set to 8mm (radius of curvature 4mm), and the radius of curvature of the damping arc groove 32-3 is set to 4.1mm to ensure clearance fit and reliable contact.

[0057] By using the damping ball head 35-2 and the damping groove 32-3, the damping ball head 35-2 can be aligned and engaged, and the elastic support force of the third spring 35-3 can effectively increase the friction force that the slide rod 32 needs to overcome to move, thereby keeping the slide rod 32 in a low position and preventing the slide rod 32 from moving upward at will. Similarly, when it is necessary to move the slide rod 32 upward, simply pull the crossbar 35-1 to disengage the damping ball head 35-2 from the damping groove 32-3, and under the elastic support of the second spring 34, the slide rod 32 will automatically move upward and reset.

[0058] In practical applications, the corner cylinder 12, fixed seat 13-1, first support block 14, sleeve 15-1, and storage sleeve 31 are all fixed to the bearing plate 11 by bolts. They can be flexibly assembled according to the actual shape of the base 21 and processing requirements, as shown in the attached diagram of the instruction manual. Figure 9 As shown.

[0059] In use, first move the product body 2 down. With the cooperation of the first support block 14 and the contour positioning groove 21-3, the contour positioning head 15-2 and the contour positioning groove 21-3, and the sliding column 13-3 and the cylindrical positioning groove 21-2, the base 21 is accurately moved down. The sliding column 13-3 moves down synchronously, and the first spring 13-5 is compressed.

[0060] As the base 21 gradually moves downward, it contacts the slide bar 32 and applies pressure to it, causing the slide bar 32 to gradually move downward. The second spring 34 is compressed, and the gas in the receiving cavity 31-1 is placed into the anti-slip airbag 33 through the ventilation groove 32-1. The anti-slip airbag 33 gradually expands and makes anti-slip contact with the middle section of the contour positioning groove 21-3, preventing the base 21 from detaching from the slide bar 32 at will. At this time, under the elastic support of the third spring 35-3, the crossbar 35-1 drives the damping ball head 35-2 to be placed into the damping arc groove 32-3 to maintain the slide bar 32 in a low position. In this state, the operator's hands can be freed, and there is no need to apply continuous pressure to the base 21.

[0061] Then, control the rotation cylinder 12 to move 90° to lock the base 21, which meets the requirements for subsequent stable processing of the base 21. When it is necessary to remove the base 21, simply pull the crossbar 35-1 to move the damping ball head 35-2 out of the damping arc groove 32-3. Under the elastic support of the second spring 34 and the first spring 13-5, the base 21 can be driven to move upward easily, which is conducive to the operator removing the base 21.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
