Technical Field

[0001] This utility model relates to the field of positioning parts technology, specifically a precision adjustment positioning part. Background Technology

[0002] In the process of using stamping dies, positioning parts are often used to ensure that the two dies can be accurately closed. Guide pins are usually installed on the punch. When the strip passes through the guide pin, its hole fits tightly with the guide pin to achieve precise positioning.

[0003] A search revealed a utility model patent with Chinese patent publication number CN110216198B, which discloses a stamping die, including an upper die base and a lower die base. The upper die base is located directly above the lower die base. A punch is provided on the bottom surface of the upper die base, and a lower template is provided on the top surface of the lower template. A pad is provided on the top surface of the lower template. A connecting mechanism is evenly provided between the pad and the lower template. A guide and buffer mechanism is provided between the upper die base and the pad. A die cavity is opened on the top surface of the lower template, and a through hole is opened on the pad, and the through hole and the die cavity are interconnected.

[0004] The aforementioned device achieves its positioning function through the cooperation of guide posts and guide slots. However, with the increase of usage time, both will inevitably experience wear or slight deformation, which may lead to inaccurate positioning. Therefore, it needs to be replaced. It is generally connected by welding, which makes it inconvenient to adjust when fixed, and there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a precision adjustment positioning part to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precision adjustable positioning part, including a positioning head and a mounting base. The positioning head is located directly above the mounting base and is shaped like a frustum of a cone. Both the positioning head and the mounting base are equipped with connecting components. The connecting components include two sliding grooves inside the positioning head, and a horizontally positioned limiting block is slidably inserted into each of the two sliding grooves. An inclined groove is formed at one end of each of the two limiting blocks that are close to each other. A screw is threadedly connected inside the positioning head, and one end of the screw is located between the two inclined grooves.

[0007] As a further preferred embodiment of this technical solution, an extension block is provided on the side of the top outer wall of the two limiting blocks that are close to each other, and a spring is fixedly connected to the side of the two extension blocks that are far from each other. Both springs are fixedly connected to the slide groove.

[0008] It allows for free assembly and disassembly of positioning parts according to requirements, making the parts modularly adjustable, more convenient to use, and offering advantages such as high flexibility and easy maintenance. The positioning head and mounting base are installed in two separate mounting slots. After the positioning head is fully inserted into the mounting slot, the screw is rotated with a screwdriver, and the screw moves upward along the positioning head. The linear movement of the screw is converted into the lateral movement of the limiting block through the inclined groove. Then, the limiting block moves out of the slide groove and into the outer annular groove, firmly fixing the position of the positioning head. The above operation is repeated to fix the mounting base in the other mounting slot. Conversely, driving the screw away from the limiting block causes the spring to drive the limiting block back into the slide groove, thus achieving quick disassembly.

[0009] As a further preferred embodiment of this technical solution, a positioning component is installed on the top of the mounting base. The positioning component includes several dampers fixedly connected to the outer wall of the top of the mounting base, and the several dampers are distributed at equal distances. One end of the top of each of the several dampers is fixedly connected to the same threaded sleeve, and a spring is fitted on the outside of each of the several dampers.

[0010] As a further preferred embodiment of this technical solution, the screw sleeve is internally threaded with a positioning sleeve, and the positioning sleeve has a positioning hole that is adapted to the positioning head.

[0011] When the positioning head and positioning sleeve are combined, the positioning sleeve extends out of the mounting groove, and the die will drive the positioning head and positioning sleeve to continue to move downward. Spring 2 can buffer the impact force to a certain extent, and the damper inside spring 2 can reduce and absorb the impact force, so as to avoid the product processed by the mold due to excessive impact force. As the usage time increases, spring 2 will shorten in length due to spring fatigue, the movable distance of the positioning sleeve will become shorter, and the buffering effect will become insufficient. At this time, the rod can be stuck inside the drive groove, and then the positioning sleeve can be rotated. The positioning sleeve will move upward along the threaded sleeve, which helps to ensure the performance of the parts.

[0012] As a further preferred embodiment of this technical solution, the top outer wall of the positioning sleeve has two equally spaced drive slots.

[0013] As a further preferred embodiment of this technical solution, a stabilizing ring is slidably fitted on the outside of the screw sleeve, and several clearance grooves are provided on the outer circumferential wall of the mounting base. A bolt is slidably inserted into the inner wall of the top of each of the clearance grooves, and the bolts are threaded into the inside of the stabilizing ring.

[0014] As a further preferred embodiment of this technical solution, both of the limiting blocks have rounded corners on their opposite edges.

[0015] This utility model provides a precision adjustable positioning part, which has the following advantages:

[0016] (1) By setting up a connecting component, this utility model can realize the free assembly and disassembly of positioning parts according to needs, so that the parts have the characteristics of modular adjustment, making them more convenient to use, and having the advantages of high flexibility and convenient maintenance. The positioning head and the mounting base are installed in two mounting slots respectively. When the positioning head is fully inserted into the mounting slot, the screw is rotated by a screwdriver, and the screw moves upward along the positioning head. The linear movement of the screw is converted into the lateral movement of the limiting block through the inclined groove. Then the limiting block moves out of the slide groove and enters the outer annular slot. The limiting block firmly fixes the position of the positioning head. Then the above operation is repeated to fix the mounting base in another mounting slot. Conversely, the screw is driven away from the limiting block, and the spring can drive the limiting block back into the slide groove, thus realizing quick disassembly.

[0017] (2) By setting up a positioning component, when the positioning head and the positioning sleeve are combined, the positioning sleeve extends out of the mounting groove, and the die will drive the positioning head and the positioning sleeve to continue to move down. The second spring can buffer the impact force to a certain extent, and the damper inside the second spring can reduce and absorb the impact force, so as to avoid the impact force being too large and causing cracks in the product processed by the mold. As the usage time increases, the second spring will shorten in length due to spring fatigue, the movable distance of the positioning sleeve will become shorter, and the buffering effect will become insufficient. At this time, the rod can be stuck inside the drive groove, and then the positioning sleeve can be rotated. The positioning sleeve will move upward along the threaded sleeve, which is beneficial to ensure the performance of the parts. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 2 and Figure 3 As shown in this embodiment, a precision adjustable positioning part includes a positioning head 1 and a mounting base 2. The positioning head 1 is located directly above the mounting base 2 and is shaped like a frustum. Both the positioning head 1 and the mounting base 2 are equipped with a connecting component 6. The connecting component 6 includes two sliding grooves 601 inside the positioning head 1. A horizontally positioned limiting block 602 is slidably inserted into each of the two sliding grooves 601. An inclined groove 603 is opened at one end of each of the two limiting blocks 602 that are close to each other. A screw 604 is threadedly connected inside the positioning head 1, and one end of the screw 604 is located between the two inclined grooves 603.

[0025] An extension block 605 is provided on the side of the top outer wall of the two limiting blocks 602 that is close to each other, and a spring 606 is fixedly connected to the side of the two extension blocks 605 that is far from each other. Both springs 606 are fixedly connected to the slide groove 601.

[0026] The positioning head 1 and the mounting base 2 are installed in the two mounting slots respectively. After the positioning head 1 is fully inserted into the mounting slot, the screw 604 is rotated with a screwdriver. The screw 604 moves upward along the positioning head 1. The linear movement of the screw 604 is converted into the lateral movement of the limiting block 602 through the inclined groove 603. Then the limiting block 602 moves out of the slide groove 601 and into the outer annular groove. The limiting block 602 firmly fixes the position of the positioning head 1. Then the above operation is repeated to fix the mounting base 2 in the other mounting slot. Conversely, the screw 604 is driven away from the limiting block 602. The spring 606 can drive the limiting block 602 to enter the slide groove 601 again, so as to achieve quick disassembly.

[0027] like Figure 2 and Figure 4 As shown, a positioning component 7 is installed on the top of the mounting base 2. The positioning component 7 includes several dampers 701 fixedly connected to the outer wall of the top of the mounting base 2. The several dampers 701 are distributed at equal distances. The top end of the several dampers 701 is fixedly connected to the same screw sleeve 703. A spring 702 is fitted on the outside of each of the several dampers 701.

[0028] The threaded sleeve 703 has a positioning sleeve 704 internally connected to it. The positioning sleeve 704 has a positioning hole that matches the positioning head 1. The punch drives the positioning head 1 to move downward, and then the positioning head 1 will be inserted into the positioning sleeve 704. Its tapered design allows it to automatically adjust its position when inserted into the positioning hole inside the positioning sleeve 704, achieving high-precision positioning.

[0029] When the positioning head 1 and the positioning sleeve 704 are combined, the positioning sleeve 704 extends out of the mounting groove, and the die will drive the positioning head 1 and the positioning sleeve 704 to continue to move downward. The second spring 702 can buffer the impact force to a certain extent, and the damper 701 inside the second spring 702 can reduce and absorb the impact force, so as to avoid the product processed by the mold being cracked due to excessive impact force. As the usage time increases, the second spring 702 will shorten in length due to spring fatigue, the movable distance of the positioning sleeve 704 will become shorter, and the buffering effect will become insufficient. At this time, the rod can be stuck inside the drive slot 705, and then the positioning sleeve 704 can be rotated. The positioning sleeve 704 will then move upward along the threaded sleeve 703, which helps to ensure the performance of the parts.

[0030] like Figure 1 and Figure 2 As shown, the top outer wall of the positioning sleeve 704 has two equally spaced drive slots 705, which make the driving process of driving the positioning sleeve 704 more efficient.

[0031] like Figure 1 and Figure 2 As shown, the outer sliding sleeve of the threaded sleeve 703 is provided with a stabilizing ring 5. The outer circumferential wall of the mounting base 2 is provided with several clearance grooves 3. A bolt 4 is slidably inserted into the inner wall of the top of each clearance groove 3. The bolts 4 are threadedly connected inside the stabilizing ring 5. The stabilizing ring 5 can further limit the position of the threaded sleeve 703, which is beneficial to ensuring the positioning effect. The stabilizing ring 5 can be disassembled by removing the bolts 4.

[0032] like Figure 3 As shown, both limiting blocks 602 have rounded corners 607 on their opposite edges, which makes the insertion process of the limiting blocks 602 toward the outer annular groove more fault-tolerant.

[0033] This utility model provides a precision adjustment positioning part, the specific working principle of which is as follows:

[0034] When the device is working, cylindrical mounting slots are made in the punch and die of the stamping die, and a larger-radius annular groove is made inside the mounting slot. Then, the positioning head 1 and the mounting base 2 are installed in the two mounting slots respectively. After the positioning head 1 is fully inserted into the mounting slot, the screw 604 is rotated by a screwdriver. The screw 604 moves upward along the positioning head 1. The linear movement of the screw 604 is converted into the lateral movement of the limiting block 602 through the inclined groove 603. Then, the limiting block 602 moves out of the slide groove 601 and into the outer annular groove. The limiting block 602 firmly fixes the position of the positioning head 1. Then, the above operation is repeated to fix the mounting base 2 in the other mounting slot. Conversely, the screw 604 is driven away from the limiting block 602, and the spring 606 can drive the limiting block 602 back into the slide groove 601, thus achieving quick disassembly. The positioning principle is: the punch drives the positioning head 1 to move downward, and then the positioning... The head 1 is inserted into the positioning sleeve 704. Its tapered design allows it to automatically adjust its position when inserted into the positioning hole inside the positioning sleeve 704, achieving high-precision positioning. When the positioning head 1 and the positioning sleeve 704 are combined, the positioning sleeve 704 extends out of the mounting groove, and the die will drive the positioning head 1 and the positioning sleeve 704 to continue to move downward. The second spring 702 can buffer the impact force to a certain extent, and the damper 701 inside the second spring 702 can reduce and absorb the impact force, avoiding excessive impact force that may cause cracks in the product processed by the mold. As the usage time increases, the second spring 702 will shorten in length due to spring fatigue, the movable distance of the positioning sleeve 704 will become shorter, and the buffering effect will become insufficient. At this time, the rod can be stuck inside the drive slot 705, and then the positioning sleeve 704 can be rotated. The positioning sleeve 704 will then move upward along the threaded sleeve 703, which helps to ensure the performance of the parts.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
