[0001] This utility model relates to the technical field of auxiliary positioning of mechanical equipment, and in particular to an auxiliary plate positioning device and a forming machine. Background Technology

[0002] In many industrial manufacturing processes, such as molding machine processing and PCB drilling, it is often necessary to precisely fix auxiliary boards to ensure the accuracy and stability of processing or operation. Traditional positioning methods often suffer from problems such as inaccurate positioning, unstable fixing, and cumbersome operation. For example, in some molding machines, the installation of auxiliary boards relies solely on simple bolt connections, which not only consumes a lot of time for adjusting the position but is also prone to displacement due to vibration during processing. In the field of PCB drilling, if the auxiliary board is not positioned well, the positional accuracy of drilling will be greatly reduced, seriously affecting the quality of the PCB board and the performance of subsequent electronic products. Therefore, there is an urgent need for an efficient, accurate, and stable auxiliary board positioning device. Utility Model Content

[0003] This invention aims to at least partially solve one of the problems in related technologies. Therefore, one objective of this invention is to provide an auxiliary plate positioning device to improve the accuracy and stability of auxiliary plate positioning.

[0004] An auxiliary plate positioning device, the auxiliary plate positioning device comprising:

[0005] An auxiliary plate, wherein at least two guide posts are protruding from the auxiliary plate and the at least two guide posts are spaced apart;

[0006] The machine tool includes a table panel, the table panel having at least two guide post holes, the at least two guide post holes being spaced apart, and one guide post hole corresponding to one guide post.

[0007] At least two fixing components are provided on the machine base and are spaced apart, and each fixing component corresponds to one guide post hole.

[0008] When one of the guide posts is inserted through a guide post hole, a fixing component is clamped to one of the guide posts.

[0009] Furthermore, the auxiliary plate is provided with four guide pillars, which are distributed in a rectangular shape at the four corners of the auxiliary plate.

When the guide post is inserted into the guide post hole, the limiting block is inserted into the groove.

[0012] Furthermore, the guide post is made of alloy steel.

[0013] Furthermore, the wall of the guide post hole is plated with hard chrome.

[0014] Furthermore, the fixing component includes a cylinder and a gripper, the cylinder being driven to connect to the gripper to drive the gripper to clamp or release.

[0015] Furthermore, a snap-fit ​​groove is radially formed on one side wall of the guide post near its end. When the gripper is clamped in the snap-fit ​​groove, the gripper is engaged within the snap-fit ​​groove.

[0030] like Figure 1 - Figure 3 As shown, the auxiliary plate positioning device provided in this application includes:

[0031] Auxiliary plate 10, at least two guide posts 11 are provided on the auxiliary plate 10, and the at least two guide posts 11 are spaced apart;

[0032] The machine includes a table panel 30, which has at least two guide post holes 31. The at least two guide post holes 31 are spaced apart, and one guide post hole 31 corresponds to one guide post 11.

[0033] At least two fixing components 50 are provided on the machine and are spaced apart. Each fixing component 50 corresponds to a guide post hole 31.

[0034] When a guide post 11 is inserted through a guide post hole 31, a fixing component 50 is clamped to the guide post 11.

[0035] The auxiliary plate 10 is provided with at least two guide posts 11, which are spaced apart. These guide posts 11 are designed to ensure the precise positioning of the auxiliary plate 10 on the machine tool.

[0036] The machine tool includes a table panel 30, which has at least two guide post holes 31. The at least two guide post holes 31 are spaced apart, and one guide post hole 31 corresponds to one guide post 11. The guide post holes 31 on the table panel 30 are designed to cooperate with the guide posts 11 on the auxiliary plate 10. Their precise position and size ensure that the auxiliary plate 10 can be stably installed on the machine tool.

[0037] At least two fixing components 50 are provided on the machine base and spaced apart. Each fixing component 50 corresponds to a guide post hole 31. The function of these fixing components 50 is to fix the guide post 11 on the auxiliary plate 10 in the guide post hole 31 of the machine base, preventing it from shifting during operation, thereby ensuring the stability and operational accuracy of the entire device. The fixing components 50 can be the cooperation between the gripper 53 and the cylinder 51, the cooperation between the gripper 53 of the motor, or the cooperation between the cylinder 51 and the pressure block. By using two oppositely arranged pressure blocks to press against each other, the guide post 11 is held and clamped, limiting its position and displacement.

[0038] When a guide post 11 is inserted through a guide post hole 31, and a fixing component 50 is clamped to a guide post 11, a stable connection is formed, which enables the auxiliary plate 10 to be accurately positioned on the machine tool, providing a reliable reference for subsequent operations.

[0039] The auxiliary plate positioning device also includes a positioning component, which comprises a positioning block and a positioning groove. The positioning block is disposed on the edge of the auxiliary plate 10, and the positioning groove is disposed on the edge of the table panel 30. The positioning block and the positioning groove cooperate to achieve precise positioning of the auxiliary plate 10 on the machine. With the above structure, the auxiliary plate positioning device of this application can ensure the stability and accuracy of the auxiliary plate 10 on the forming machine, thereby improving production efficiency and product quality.

[0040] Taking the application of molding machine equipment as an example, the fixing component 50 is the fixing cylinder 51. Before processing plastic products, the auxiliary plate 10 with molding process auxiliary structures (such as ejection devices for product demolding, heat conduction structures to improve molding temperature distribution, etc.) is prepared, ensuring that the guide post 11 is clean and free of foreign objects. The auxiliary plate 10 is moved to the top of the machine table panel 30. The operator, with visual observation and simple positioning tools, aligns the guide post 11 with the guide post hole 31 and slowly lowers the auxiliary plate 10. The guide post 11 is smoothly inserted into the guide post hole 31, completing the initial positioning. At this time, the control system automatically triggers the action of the fixing cylinder 51. The clamp of the fixing cylinder 51 extends according to the preset program and tightly clamps the guide post 11. The clamping status and pressure data of the fixing cylinder 51 can be viewed in real time on the display screen to ensure that the auxiliary plate 10 is fixed in place. Subsequently, the molding machine can be started for normal plastic product molding. During the processing, the auxiliary plate 10 remains stable, ensuring the quality and precision of the molded product.

[0041] Furthermore, the auxiliary plate 10 is provided with four guide pillars 11, which are distributed in a rectangular shape at the four corners of the auxiliary plate 10. The table panel 30 is provided with four guide pillar holes 31, which are distributed in a rectangular shape at the four corners of the table panel 30. The number of fixing components 50 is four, which are all distributed in a rectangular shape at the four corners of the machine.

[0042] In this invention, the auxiliary plate 10 is designed to be equipped with four guide posts 11. These guide posts 11 are evenly distributed at the four corners of the auxiliary plate 10, forming a rectangular layout. Simultaneously, four guide post holes 31 are correspondingly formed on the table panel 30. These guide post holes 31 are also distributed at the four corners of the rectangle, corresponding one-to-one with the positions of the guide posts 11 on the auxiliary plate 10. Furthermore, to ensure the stability and reliability of the structure, the number of fixing components 50 is also set to four. These fixing components 50 are also distributed at the corresponding positions on the machine tool according to the four corners of the rectangle, matching the layout of the guide posts 11 and guide post holes 31, thereby ensuring the stability and precise alignment of the entire structure.

[0043] In practical applications, each fixing component 50 includes a cylinder 51 and a chuck. The cylinder 51 pneumatically controls the extension and retraction of the chuck. The chuck is designed to tightly fit the outer diameter of the guide post 11, ensuring that the auxiliary plate 10 does not shift during clamping. Furthermore, to accommodate auxiliary plates 10 of different sizes, the clamping part of the chuck is designed to be adjustable, allowing for simple mechanical adjustments to accommodate guide posts 11 of different diameters.

[0044] The control system employs advanced sensor technology to monitor the clamping status and pressure data in real time, ensuring the stability of the auxiliary plate 10 during the molding process. Once the auxiliary plate 10 is positioned, the control system automatically records the current clamping pressure value and continuously monitors it during subsequent production. If an abnormal pressure value is detected, the system will immediately issue an alarm and stop the molding machine to prevent production defects caused by the displacement of the auxiliary plate 10.

[0045] Furthermore, the end of the guide post 11 is hemispherical.

[0046] Specifically, the end of the guide post 11 is hemispherical, facilitating initial guidance when inserted into the guide post hole 31 and reducing collisions and scratches during insertion. Furthermore, the hemispherical end design of the guide post 11 also helps provide a certain degree of self-alignment during the positioning of the auxiliary plate 10, allowing the auxiliary plate 10 to be more accurately aligned with the center line of the molding machine during clamping. This design not only improves the positioning accuracy of the auxiliary plate 10 but also reduces the risk of damage to the auxiliary plate 10 due to inaccurate positioning. In actual operation, this self-alignment function greatly simplifies the installation process of the auxiliary plate 10 and improves production efficiency.

[0047] To further improve the performance of the auxiliary plate positioning device, this embodiment also includes a positioning assistance system for the auxiliary plate 10. This system includes a set of precision guiding devices that work in conjunction with the guide post 11 and the chuck to ensure the accuracy of the auxiliary plate 10 during insertion and positioning. The guiding devices are made of highly wear-resistant materials, capable of withstanding prolonged use without losing their accuracy. During the insertion of the auxiliary plate 10, the guiding devices guide the auxiliary plate 10 along a predetermined path, thereby preventing damage to the auxiliary plate 10 or positioning deviations caused by improper operation.

[0048] Furthermore, to accommodate auxiliary plates 10 of varying thicknesses, this device is equipped with an adjustable clamping force control system. This system automatically adjusts the clamping force according to the thickness of the auxiliary plate 10, ensuring uniform and stable clamping on auxiliary plates 10 of different thicknesses. The clamping force is adjusted via a precision hydraulic system that accurately controls the pressure of the hydraulic cylinder, thereby achieving fine-tuning of the clamping force.

[0049] Furthermore, the side wall of the guide post 11 is provided with a groove 111 along the axial direction, and the hole wall of the guide post hole 31 is provided with a limiting block 311 along the axial direction. When the guide post 11 passes through the guide post hole 31, the limiting block 311 is inserted into the groove 111.

[0050] The design of the groove 111, in conjunction with the limiting block 311, ensures that when the guide post 11 is inserted into the guide post hole 31, the limiting block 311 is inserted into the groove 111. This serves two purposes: first, it increases the amount of lubricating oil stored between the guide post 11 and the guide post hole 31, reducing the coefficient of friction and facilitating insertion and removal; second, it can play a role in preventing rotation to a certain extent, ensuring the consistency of the installation angle of the auxiliary plate 10.

[0051] To further enhance the stability and durability of the device, this embodiment also employs a special surface treatment technique. The contact surfaces of the guide post 11 and the guide post hole 31 are hardened, improving surface hardness and wear resistance, thereby extending the service life of the device. Simultaneously, the surface treatment also provides excellent self-lubricating properties, reducing reliance on lubricating oil during frequent operation and lowering maintenance costs.

[0052] Furthermore, to accommodate auxiliary plates 10 of different sizes and shapes, this device is designed with a flexible adjustment mechanism. Through this mechanism, users can adjust the positions of the guide posts 11 and the clamps according to actual needs to accommodate auxiliary plates 10 of different specifications. This design not only improves the versatility of the device but also makes operation simpler and faster.

[0053] Furthermore, the guide post 11 is made of alloy steel.

[0054] Specifically, the guide post 11 is made of high-strength alloy steel and undergoes heat treatment processes such as quenching and tempering to achieve a surface hardness of HRC55-60, while maintaining good toughness in the core, ensuring that it does not deform or wear under long-term insertion and removal and load-bearing conditions.

[0055] Furthermore, the hole wall of the guide post hole 31 is plated with hard chrome.

[0056] Specifically, the surface of the guide post 11 undergoes a special plating treatment to further enhance its wear resistance and corrosion resistance. The plating uses a hard chrome plating with excellent wear resistance, which not only effectively prevents wear on the guide post 11 during use but also resists the erosion of various chemicals, thus ensuring the long-term stability and reliability of the guide post 11. Furthermore, the hard chrome plating also has good self-lubricating properties, reducing friction and making the insertion and removal of the guide post 11 smoother, extending the maintenance cycle of the device.

[0057] Furthermore, the fixing component 50 includes a cylinder 51 and a gripper 53, with the cylinder 51 driving the gripper 53 to clamp or release.

[0058] Specifically, the described fixing assembly 50 consists of a cylinder 51 and a gripper 53, which work together through a drive connection. Specifically, the cylinder 51 is connected to the gripper 53 via its internal mechanical structure. When the cylinder 51 receives a control signal and begins operation, it enables the gripper 53 to perform precise clamping or releasing actions through this drive connection. This design allows the entire fixing assembly 50 to securely fix or release workpieces as needed, thus playing an important role in automated production lines.

[0059] Furthermore, a snap-fit ​​groove 113 is radially provided on one side wall of the guide post 11 near the end. When the gripper 53 is clamped in the snap-fit ​​groove 113, the gripper 53 is engaged in the snap-fit ​​groove 113.

[0060] Specifically, a locking groove 113 is specially designed on one side wall near the end of the guide post 11 in the radial direction. This design allows the gripper 53 to be clamped and fixed in the locking groove 113. When the gripper 53 is correctly engaged in the locking groove 113, it will be firmly locked in a specific position on the guide post 11, thereby ensuring a stable connection between the gripper 53 and the guide post 11.

[0061] Furthermore, the end of the gripper 53 has a protrusion on the opposite side, and the locking groove 113 has a recessed slot 115. When the gripper 53 is clamped on the guide post 11, the protrusion is inserted into the slot 115.

[0062] Specifically, the ends of the grippers 53 have protrusions on opposite sides. These protrusions are designed to mate with specific structures on the guide post 11 when the grippers 53 are clamped. Specifically, the locking groove 113 has recessed slots 115, the shape and size of which match the protrusions at the ends of the grippers 53. When the grippers 53 are clamped on the guide post 11, the protrusions at the ends of the grippers 53 can be inserted into the slots 115, thereby achieving a secure connection between the grippers 53 and the guide post 11.

[0063] Furthermore, the inner side of the chuck is designed with a protruding structure that matches the annular groove 111 of the guide post 11. The purpose of this design is to allow the protrusion to embed into the annular groove 111 on the guide post 11 when clamping the guide post 11. This embedding method can further enhance the stability of clamping, effectively prevent unnecessary rotation of the guide post 11 during use, and ensure the stability and reliability of the entire clamping system.

[0064] This utility model also proposes a molding machine, which includes an auxiliary plate positioning device. The specific structure of the auxiliary plate positioning device is as described in the above embodiments. Since this molding machine adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0065] The auxiliary board positioning device in this application can be applied to molding machines, but is not limited to molding machines. It can also be applied to PCB drilling equipment, PCB etching equipment, PCB electroplating equipment, PCB testing equipment, etc., without limitation.
