Description

Technical Field

[0001] This invention belongs to the field of automated positioning and installation in engineering, specifically an automated positioning and installation device for engineering. Background Technology

[0002] Automated positioning and installation in engineering, as a crucial link in modern industrial production, deeply integrates knowledge from multiple disciplines such as mechanical engineering, automation control, and computer science. It plays an irreplaceable role in numerous industries, including automobile manufacturing, aerospace, and electronic equipment production. It aims to achieve precise installation and fixation of workpieces in designated positions using automation technology and equipment, thereby improving production efficiency, ensuring product quality, reducing labor costs, and minimizing errors caused by human factors.

[0003] At the automation control level, programmable logic controllers (PLCs), industrial computers, and other equipment serve as core control units, precisely regulating various actions during the installation process according to pre-set programs. Taking an automotive engine assembly line as an example, a PLC can accurately control the gripping, moving, and placing actions of robotic arms, ensuring that each engine component is assembled in a predetermined order and with the required precision.

[0004] In terms of mechanical design, high-precision fixtures, guide rails, transmission mechanisms, and other components are the hardware foundation for automated positioning and installation. For example, in semiconductor manufacturing equipment, the precision and rigidity of the mechanical structure directly determine the accuracy of chip installation; any slight deviation can lead to a decrease in chip performance or even render the chip unusable.

[0005] Sensor technology provides real-time and accurate information feedback for automated positioning and installation. Pressure sensors can monitor the clamping force during the installation process in real time, preventing damage to the workpiece due to excessive clamping force or loosening due to insufficient clamping force; displacement sensors can accurately measure the position and movement trajectory of the workpiece, providing key data for the control system to adjust the installation actions in a timely manner.

[0006] Currently, many companies use customized clamping devices based on the specific shape of the workpiece for clamping polygonal workpieces. While this method can meet the clamping accuracy requirements to a certain extent, it incurs extremely high costs. Customized clamping devices require specialized design and manufacturing processes, involving multiple stages such as mold development, material procurement, and processing, each with its own costs. Moreover, different shapes of polygonal workpieces require redesign and remanufacturing, further increasing costs. For example, in the aerospace field, the customized cost of clamping devices for some complex polygonal components can reach hundreds of thousands of yuan or even higher. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides an automated positioning and installation device for engineering applications. This solves the problems of existing technologies that require customized clamping devices based on the specific shape of polygons, resulting in high costs, long production preparation times, poor versatility, complex production, and technical difficulties and talent shortages for small enterprises and research institutions.

[0008] An automated positioning and installation device for engineering includes a clamping table mechanism, several clamping head mechanisms, several connecting mechanisms, and a gas compression assembly.

[0009] The clamping platform mechanism includes a clamping platform body, a support base fixed to the lower end of the clamping platform body, a clamping groove on the upper side of the clamping platform body, several movable grooves on the outer side of the clamping platform body, several guide rods fixed to the bottom of the clamping platform body, several piston chambers inside the clamping platform body, and piston chambers inside the support base. A sealing connecting pipe is fixed between the clamping platform body and the support base, and the piston chambers are connected through the sealing connecting pipe.

[0010] The clamping head mechanism includes a round rod and a spring. A retaining ring is fixed at the middle of the outer side of the round rod. A rubber head is fixed at one end of the round rod, and a square slider is fixed at the other end of the round rod. A trapezoidal groove is opened in the square slider. The round rod is inserted and fitted into the clamping table body. The spring is sleeved on the outer side of the round rod. The spring and the retaining ring are limited and slidably fitted into the movable groove. The rubber head is located in the clamping groove, and the square slider is located on the outer side of the clamping table body.

[0011] The connecting mechanism includes a U-shaped bracket, one end of which is fixed with a trapezoidal slider, and the other end of which is fixed with a small piston. A guide hole is provided in the middle of the U-shaped bracket. The U-shaped bracket is limited and slidably embedded in a guide rod through the guide hole. The trapezoidal slider is slidably embedded in a trapezoidal groove, and the small piston is slidably embedded in a piston chamber.

[0012] Preferably, a guide rod is also fixed to the outer side of the square slider;

[0013] The outer side of the clamping platform body is also provided with a guide groove;

[0014] The guide rod is fitted into the guide groove by a limiting sliding clip.

[0015] Preferably, the gas compression assembly includes a drive component, and a large piston is fixed to the upper end of the drive component.

[0016] Preferably, the large piston is one of a pneumatic cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0017] Preferably, the outer surface of the rubber head is provided with anti-slip texture, which is wavy or striped, to increase the friction when the rubber head contacts the polygonal workpiece and prevent the workpiece from sliding during subsequent installation.

[0018] Preferably, it also includes a control system, which includes a sensor module, a controller, and a drive control circuit;

[0019] The sensor module includes a pressure sensor, which is installed at the contact point between the rubber head and the polygonal workpiece. The pressure sensor is used to detect the clamping force in real time and transmit the detected pressure signal to the controller.

[0020] The controller receives signals from the pressure sensor and makes judgments based on the preset clamping force range. When the detected clamping force exceeds the preset range, the controller sends a control signal to the drive component through the drive control circuit to adjust the output of the drive component, thereby changing the movement of the large piston and ultimately adjusting the clamping force of the clamping head mechanism on the polygonal workpiece to keep it within the preset range.

[0021] Preferably, it also includes a human-computer interaction system, which includes a display module and an input module;

[0022] The display module is connected to the controller and is used to display the current working status information of the polygonal workpiece, including the clamping force and the working parameters of the gas compression component;

[0023] The input module is used to receive instructions from the operator. The operator sets the clamping force preset range and the working mode of the gas compression component through the input module. The input module transmits the instructions input by the operator to the controller, and the controller adjusts and controls the system accordingly based on the received instructions.

[0024] Preferably, a limiting groove is also provided on the adjacent rubber head;

[0025] Several of the aforementioned limiting slots are also jointly embedded in an elastic band, and several elastic positioning balls are fixed on the elastic band.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The large piston is driven by a drive component, changing the gas pressure in piston chamber two. This pressure change in piston chamber one is then synchronized via a sealed connecting pipe, pushing the small piston to slide. The small piston drives a U-shaped bracket to move precisely along guide rod one. A trapezoidal slider at one end of the U-shaped bracket slides within the trapezoidal groove of a square slider, pushing the square slider to move. Ultimately, the rubber head at one end of the round rod approaches and clamps the polygonal workpiece in the clamping groove. Through the linkage design of pneumatic transmission and mechanical structure, the clamping action is automated and precise, eliminating the need for manual operation, greatly improving clamping efficiency, reducing errors that may be caused by manual operation, and providing a stable and reliable clamping foundation for subsequent installation.

[0028] By creating limiting grooves on adjacent rubber heads and embedding an elastic band within these grooves, while simultaneously fixing several elastic positioning balls on the elastic band, the elastic band and positioning balls effectively restrain potentially movable parts on the polygonal workpiece when the rubber heads abut against it. This device utilizes the characteristics of elastic elements, achieving precise positioning and fixation of moving parts without the need for additional complex mechanical structures. It avoids interference with installation operations caused by shaking or displacement of moving parts, providing a stable and reliable working environment for the installation process.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figures 1 to 8 As shown:

[0042] Example 1: The present invention provides an automated positioning and installation device for engineering, including a clamping platform mechanism 1, a plurality of clamping head mechanisms 2, a plurality of connecting mechanisms 3 and a gas compression assembly 4;

[0043] The clamping platform mechanism 1 includes a clamping platform body 11, a support base 12 fixed at the lower end of the clamping platform body 11, a clamping groove 13 opened on the upper side of the clamping platform body 11, a number of movable grooves 14 opened on the outer side of the clamping platform body 11, a number of guide rods 15 fixed at the bottom of the clamping platform body 11, a number of piston chambers 16 opened inside the clamping platform body 11, a piston chamber 17 opened inside the support base 12, and a sealing connecting pipe 18 fixed between the clamping platform body 11 and the support base 12. The piston chambers 16 and 17 are connected through the sealing connecting pipe 18.

[0044] The clamping head mechanism 2 includes a round rod 21 and a spring 22. A retaining ring 23 is fixed at the middle position of the outer side of the round rod 21. A rubber head 24 is fixed at one end of the round rod 21, and a square slider 25 is fixed at the other end of the round rod 21. A trapezoidal groove 26 is opened in the square slider 25. The round rod 21 is inserted through and embedded in the clamping table body 11. The spring 22 is sleeved on the outer side of the round rod 21. The spring 22 and the retaining ring 23 are limited and slidably embedded in the movable groove 14. The rubber head 24 is located in the clamping groove 13, and the square slider 25 is located on the outer side of the clamping table body 11.

[0045] The connecting mechanism 3 includes a U-shaped bracket 31, a trapezoidal slider 32 fixed at one end of the U-shaped bracket 31, a small piston 33 fixed at the other end of the U-shaped bracket 31, a guide hole 34 in the middle of the U-shaped bracket 31, the U-shaped bracket 31 is limited and slidably embedded in the guide rod 15 through the guide hole 34, the trapezoidal slider 32 is slidably embedded in the trapezoidal groove 26, and the small piston 33 is slidably embedded in the piston chamber 16.

[0046] As can be seen from the above, when the polygonal workpiece is subsequently installed and clamped, the gas compression assembly 4 starts to work. Its drive component 41 drives the large piston 42 to move, causing a change in the gas pressure in piston chamber 2 17. Since piston chamber 1 16 and piston chamber 2 17 are connected by a sealed connecting pipe 18, the gas pressure in piston chamber 1 16 also changes accordingly. This pressure change pushes the small piston 33 to slide in piston chamber 1 16, and the small piston 33 drives the U-shaped bracket 31 connected to it to move along the guide rod 1 15.

[0047] When the U-shaped bracket 31 moves, the trapezoidal slider 32 at one end slides in the trapezoidal groove 26 within the square slider 25, thereby pushing the square slider 25 to move. The square slider 25 drives the round rod 21 to move on the clamping table body 11, and the rubber head 24 at one end of the round rod 21 moves closer to the polygonal workpiece in the clamping groove 13. During this process, the spring 22 and the retaining ring 23 slide within the movable groove 14, and the spring 22 plays a reset role, so that when the driving force is removed, the round rod 21 can automatically reset, which is convenient for the next clamping and fixing.

[0048] like Figure 4 , 6 and Figure 8 As shown:

[0049] Example 2: This example is basically the same as the previous example, except that a guide rod 27 is also fixed on the outside of the square slider 25;

[0050] A guide groove 19 is also provided on the outer side of the clamping platform body 11;

[0051] The guide rod 27 is limited and slidably embedded in the guide groove 19.

[0052] Specifically, the gas compression assembly 4 includes a drive component 41, and a large piston 42 is fixed to the upper end of the drive component 41.

[0053] Specifically, the large piston 42 is one of a cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0054] Specifically, the outer surface of the rubber head 24 is provided with anti-slip texture 241, which is wavy or striped to increase the friction between the rubber head 24 and the polygonal workpiece and prevent the workpiece from sliding during subsequent installation.

[0055] As can be seen from the above, the sliding of the small piston 33 drives the U-shaped bracket 31 to move along the guide rod 15. The trapezoidal slider 32 at one end of the U-shaped bracket 31 slides in the trapezoidal groove 26 of the square slider 25, pushing the square slider 25 to move. At this time, the guide rod 27 fixed on the outside of the square slider 25 slides in the guide groove 19 on the outside of the clamping table body 11, thereby providing more precise guidance for the movement of the square slider 25, making its movement more stable and straight, and avoiding the influence of movement deviation on the clamping effect.

[0056] The anti-slip texture 241 on the outer surface of the rubber head 24, whether wavy or striped, can greatly increase the friction between the rubber head 24 and the polygonal workpiece, effectively preventing the workpiece from sliding during installation, ensuring the accuracy and quality of installation, and improving the stability and reliability of the entire clamping and installation process.

[0057] Example 3: This example is basically the same as the previous example, except that it also includes a control system, which includes a sensor module, a controller, and a drive control circuit;

[0058] The sensor module includes a pressure sensor, which is located at the contact point between the rubber head 24 and the polygonal workpiece. The pressure sensor is used to detect the clamping force in real time and transmit the detected pressure signal to the controller.

[0059] The controller receives the signal from the pressure sensor and makes a judgment based on the preset clamping force range. When the detected clamping force exceeds the preset range, the controller sends a control signal to the drive component 41 through the drive control circuit, adjusts the output of the drive component 41, and then changes the movement of the large piston 42, ultimately adjusting the clamping force of the clamping head mechanism 2 on the polygonal workpiece so that it remains within the preset range.

[0060] Specifically, it also includes human-computer interaction systems, which include display modules and input modules;

[0061] The display module is connected to the controller and is used to display the current working status information of the polygonal workpiece, including the clamping force and the working parameters of the gas compression component 4.

[0062] The input module is used to receive instructions from the operator. The operator sets the clamping force preset range and the working mode of the gas compression component 4 through the input module. The input module transmits the instructions input by the operator to the controller, and the controller adjusts and controls the system accordingly based on the received instructions.

[0063] As can be seen from the above, during operation, the pressure sensor located at the contact point between the rubber head 24 and the polygonal workpiece detects the clamping force in real time and transmits the signal to the controller.

[0064] After receiving the signal from the pressure sensor, the controller makes a judgment based on the preset clamping force range. If the detected clamping force exceeds the preset range, the controller will send a control signal to the drive component 41 through the drive control circuit to adjust the output of the drive component 41 and change the movement of the large piston 42, thereby accurately adjusting the clamping force of the clamping head mechanism 2 on the polygonal workpiece, ensuring that it is always stable within the preset range. This effectively avoids the problem of the workpiece being damaged due to excessive clamping force or the workpiece sliding during subsequent installation due to insufficient clamping force, thus ensuring the reliability and stability of clamping.

[0065] Meanwhile, the human-machine interface system's display module shows the current system's operating status information in real time, such as the clamping force and the operating parameters of the gas compression component 4, allowing operators to monitor the system's operation at any time. Operators can input commands to set the preset range of the clamping force and the operating mode of the gas compression component 4, and the controller will adjust and control the system accordingly.

[0066] like Figure 9 and Figure 10 As shown:

[0067] Example 4: This example is basically the same as the previous example, except that a limiting groove 28 is also provided on the adjacent rubber head 24;

[0068] Several limiting slots 28 are also embedded in the elastic band 51, and several elastic positioning balls 52 are fixed on the elastic band 51.

[0069] As can be seen from the above, when the rubber head 24 is pressed against the polygonal workpiece, if there are still movable parts on the outside of the polygonal workpiece, the elastic band 51 is inserted into the limiting groove 28. Through several elastic positioning balls 52 and the elastic band 51, the movable parts on the outside of the polygonal workpiece can be restrained, thereby avoiding the influence of the movable parts on the installation process. This greatly enhances the stability of the clamping, especially for polygonal workpieces with complex shapes that are prone to displacement during installation. It can effectively ensure the installation accuracy, reduce the error caused by workpiece movement, improve the quality and consistency of the product, and enable the entire system to complete the task more efficiently and accurately.

[0070] The embodiments of the present invention are given for the purposes of illustration and description. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions and variations made by those skilled in the art to the above embodiments within the scope of the present invention should be included within the protection scope of the present invention.
