[0001] This invention relates to the field of automatic pressing technology, and in particular to a single-station multi-head pressing device and its pressing method. Background Technology

[0002] In the field of mechanical assembly, various components, such as oil seals and bushings, need to be press-fitted into housing parts.

[0014] Furthermore, the end of the drive rod of the first cylinder is provided with an I-beam retaining sleeve;

[0015] The drive plate is provided with a U-shaped groove for the snap-fit ​​sleeve to slide into. In addition, the side of the U-shaped groove away from the first cylinder is provided with a force-bearing step surface.

[0016] Furthermore, end limiting members are provided at both ends of the mounting bracket.

[0017] Furthermore, at least one intermediate limiting member is provided at the middle position of the mounting bracket, and the intermediate limiting member is correspondingly provided with the pressure rod at the middle position;

[0020] The telescopic shaft is provided with a T-slot at the end near the second cylinder, and the drive rod end of the second cylinder is provided with a T-block that mates with the T-slot.

[0021] The telescopic shaft extends out of the outer sleeve and has an abutting surface on the side facing the limiting block;

[0022] The outer sleeve is provided with a guide shaft perpendicular to the telescopic shaft.

[0023] Furthermore, the downward driving assembly includes a third cylinder and an alignment block. The third cylinder is disposed above the gantry, and the driving rod of the third cylinder extends into the driving area and connects to the alignment block.

[0024] The alignment block is provided with a groove at the end away from the third cylinder for the pressure rod to enter, and the groove is provided through the pressure rod along the sliding direction;

[0025] Wherein, a pressure table correction assembly is provided at the connection position between the pressure rod and the alignment block. The pressure table correction assembly includes a guide block and a connecting column group. The guide block is fixed on the gantry frame through the connecting column group.

[0026] The guide block has a through hole in the middle for the alignment block to pass through, and the bottom surface of the guide block facing the pressure rod has a guide groove. The guide groove extends through the pressure rod in the sliding direction, and the sliding groove of the alignment block is flush with the edge of the guide groove to form a smooth channel.

[0027] Furthermore, the pressure table correction assembly also includes a guide component;

[0028] The guide component includes a pressure plate located directly below the guide block and a guide sleeve fixedly mounted on the gantry frame. The slide rod inside the guide sleeve extends into the drive area and is connected to the pressure plate.

[0029] The alignment block passes through the guide block and is fixed on the pressure plate. The pressure plate is provided with a strip groove for sliding of multiple pressure rods.

[0033] Step 1: Place the workpiece in the pressing station of the worktable;

[0034] Step 2: Start the first driving component to drive the translational slide to slide in the horizontal direction. When the pressure rod corresponding to the first process moves above the pressing station, the first driving component stops moving. The pressing drive assembly presses down on the pressure rod corresponding to the first process to realize the pressing of the part to be pressed in the first process.

[0035] Step 3: After completing the first pressing process, the pressing drive assembly drives the pressing rod to return to its initial height. Repeat step 2 to press the parts to be pressed on the pressing rod of the next process until all pressing operations are completed.

[0036] The beneficial effects of this invention are as follows: The gantry frame and mounting frame provide stable support for the replacement and pressing of the pressure rod, ensuring the stability of the pressure rod during pressing.

Furthermore, by connecting the pressing drive component with different pressure rods, multiple pressing heads can be pressed at the same station, improving production efficiency, effectively ensuring pressing accuracy, and further guaranteeing product quality.

[0037] This invention, through the setting of guide blocks and guide components, prevents the pressure rod from shifting during replacement, ensuring the positioning accuracy of the pressure rod. During the pressing process, the pressure plate moves downward synchronously with the pressure rod, effectively ensuring the stability of the center of gravity of the pressure rod during pressing and improving the pressing accuracy.

[0053] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0054] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0056] like Figures 1 to 13 The single-station multi-head pressing device shown includes: a worktable 1, a gantry frame 2, a mounting frame 3, a pressing assembly 4, and a pressing drive assembly 5. The worktable 1 has a pressing station; the gantry frame 2 is mounted on the worktable 1; the mounting frame 3 is suspended on the gantry frame 2 so that the area between the gantry frame 2 and the worktable 1 is vertically divided into a driving area and a pressing area; the pressing assembly 4 is mounted on the mounting frame 3 and includes a translational slide 41, and multiple pressing rods 42 arranged side by side on the translational slide 41 and moving vertically, and a first driving member 43 that drives the translational slide 41 to translate horizontally. One end of the multiple pressing rods 42 passes through the mounting frame 3 and extends into the driving area, and the pressing head corresponding to the part to be pressed is installed at the end located in the pressing area; the pressing drive assembly 5 is mounted on the gantry frame 2 and is used to press down the pressing rods 42 that have been translated to the pressing station.

[0057] like Figures 1-2 As shown, in this invention, both the gantry frame 2 and the mounting frame 3 consist of a plate and four support columns set on the plate. The mounting frame 3 is suspended at the center of the gantry frame 2 and forms an area for installing the workpiece between it and the worktable 1. The plate of the mounting frame 3 divides the distance between the plate of the gantry frame 2 and the table surface of the worktable 1 into a driving area and a pressing area. The plate of the mounting frame 3 is provided with a clearance groove along the sliding direction. Multiple pressure rods 42 in the pressing assembly 4 pass through the clearance groove into the driving area, while the other end is located in the pressing area. In addition, the distance between the multiple pressure rods 42 arranged side by side is determined according to the size of the workpiece to be pressed.

[0058] Before pressing, according to the pressing procedure, the worker sequentially loads the parts to be pressed onto the corresponding pressing heads, and activates the first drive unit 43 to drive the translational slide 41 to move horizontally. Figures 9-10 As shown, when the first-process pressure rod 42 is moved to directly above the press-fitting station, the axis of the pressure rod 42 is collinear with the axis of the mounting cavity of the workpiece. The first drive component 43 stops moving, and the downward drive component presses down on the first pressure rod 42 to press the workpiece to be pressed into the mounting cavity of the workpiece. After the first-process press-fitting operation is completed, the downward drive component 5 drives the first-process pressure rod 42 to move upward and return to the initial height position. At this time, the first drive component 43 drives the translation slide 41 to move again, as shown. Figure 11As shown, the second-stage pressing rod 42 is moved above the pressing station. The pressing drive unit presses down on the second-stage pressing rod 42 to press the workpiece on the pressing head into the mounting cavity of the workpiece. After the second-stage pressing operation is completed, the pressing drive assembly 5 drives the second-stage pressing rod 42 to move upward and return to the initial height position. Figure 12 As shown, the above steps are repeated sequentially to press the third-process pressure rod 42 until all the parts to be pressed on all the pressure heads are pressed into the workpiece, thus completing the assembly of the workpiece. In this invention, by arranging multiple pressure rods 42 side by side on the translation slide 41, the first driving component 43 drives the translation slide 41 to translate, which can move the pressure rods 42 one by one to the pressing station. The downward pressing drive component 5 is connected to different pressure rods 42, which can realize the pressing operation of multiple pressure heads at the same station, improve production efficiency, effectively ensure pressing accuracy, and further ensure product quality.

[0059] In a preferred embodiment of the present invention, such as Figures 3-4 As shown, the translational slide 41 includes a support plate 411 and a sliding assembly 412. The sliding assembly 412 is disposed between the support plate 411 and the mounting frame 3. Specifically, the sliding assembly 412 includes a guide rail assembly and multiple sliders that cooperate with the guide rail assembly. The guide rail assembly is fixed below the mounting frame 3. The support plate 411 is slidably disposed relative to the mounting frame 3 through multiple sliders. This enables the support plate 411 to achieve stable horizontal translational movement with high accuracy and reliability. The first driving component 43 includes a first cylinder 431 and a driving plate 432. The first cylinder 431 is fixed on the mounting frame 3, and the driving plate 432 is fixed on the support plate 411. The driving rod of the first cylinder 431 is connected to the driving plate 432 to drive multiple pressure rods 42 to slide sequentially to the pressing position. Through the arrangement of the translational slide 41 and the first driving component 43, accurate positioning and pressing operations can be achieved for parts to be pressed at different positions.

[0060] To facilitate the installation of the first drive component 43 on the mounting bracket 3 and the translational slide 41, such as Figure 5 As shown, the drive rod end of the first cylinder 431 is provided with an I-shaped retaining sleeve; the drive plate 432 is provided with a U-shaped groove 521 for the retaining sleeve to slide into, allowing the retaining sleeve to slide smoothly into the groove 521 for quick connection, effectively preventing the drive rod from shifting or disengaging during movement, ensuring the stability and accuracy of the pressure rod 42. In addition, the side of the U-shaped groove 521 away from the first cylinder 431 is provided with a force-bearing stepped surface. When the drive rod applies pressure, the force is concentrated on the stepped surface, increasing the stability and strength of the connection, avoiding deformation or breakage of the drive plate 432, and ensuring the reliability and safety of the device.

[0061] like Figures 6-7As shown, end limiting members 6 are provided at both ends of the mounting bracket 3, which can accurately limit the movement distance of the translation slide 41 and prevent the translation slide 41 from exceeding the predetermined range, so that the pressure rod 42 at the edge position can be accurately translated to the predetermined position, thereby ensuring the accuracy and consistency of the pressing.

[0062] In this invention, multiple pressure rods 42 need to stop accurately at the pressing station one by one during the translation process. To improve the positioning accuracy of the pressure rods 42, preferably, at least one intermediate limiting member 7 is provided at the middle position of the mounting frame 3, and the intermediate limiting member 7 is correspondingly set with the pressure rods 42 at the middle position. The intermediate limiting member 7 includes a limiting block 71 fixed on the translation slide 41 and a baffle assembly 72 set on the mounting frame 3. By blocking the limiting block 71 with the baffle assembly 72, the displacement distance of the translation slide 41 is limited, avoiding instability caused by excessive movement or exceeding the range of the translation slide 41, and ensuring the stability and accuracy of the pressing process. In addition, since the baffle assembly 72 is fixed on the mounting frame 3, the baffle assembly 72 is always set corresponding to the pressing station when the translation slide 41 moves. Therefore, when there are multiple intermediate limiting members 7, by adding the limiting block 71, multiple preset positions can be restricted, improving the applicability and diversified production capacity of the device.

[0063] As a preferred embodiment of the above, such as Figure 8 As shown, the baffle assembly 72 includes an outer sleeve 721, a telescopic shaft 722, and a second cylinder 723. The telescopic shaft 722 is coaxially disposed inside the outer sleeve 721, and the second cylinder 723 is disposed on the outer sleeve 721. By controlling the telescopic movement of the second cylinder 723, the telescopic shaft 722 can be reciprocated within the outer sleeve 721, thereby adjusting the length of the baffle. A T-slot is provided at the end of the telescopic shaft 722 near the second cylinder 723, and the end of the drive rod of the second cylinder 723 is provided with a groove that matches the T-slot. The T-shaped block is designed to ensure a stable connection between the telescopic shaft 722 and the second cylinder 723, allowing the driving force to be transmitted smoothly and ensuring the accurate position and stability of the baffle. The telescopic shaft 722 has an abutment surface on the side facing the limiting block 71, which provides stable support during the blocking process of the limiting block 71. In order to ensure that the abutment surface remains perpendicular during the telescopic process, the outer sleeve 721 has a guide shaft 724 perpendicular to the telescopic shaft 722.

[0064] In a preferred embodiment of the present invention, such as Figure 10As shown, the downward pressure drive assembly 5 includes a third cylinder 51 and an alignment block 52. The third cylinder 51 is positioned above the gantry 2, and its drive rod extends into the drive area and connects to the alignment block 52. The alignment block 52 has a groove 521 at its end away from the third cylinder 51 for the pressure rod 42 to enter. The groove 521 extends through the pressure rod 42 along its sliding direction. When the pressure rod 42 moves to the pressing position, its end slides into the groove 521, and the third cylinder 51 applies appropriate downward pressure to the pressure rod 42 to achieve a precise pressing effect. However, before the pressure rod 42 enters the groove 521, its end extending into the drive area is in a free state. Therefore, to ensure the pressure rod can smoothly enter the alignment block 52, the third cylinder 51 applies appropriate downward pressure to the pressure rod 42. A pressure table correction assembly 53 is provided at the connection position with the alignment block 52. The pressure table correction assembly 53 includes a guide block 531 and a connecting column assembly 532. The guide block 531 is fixed to the gantry frame 2 through the connecting column assembly 532. A through hole 531a for the alignment block 52 to pass through is provided in the middle position of the guide block 531, and a guide groove 531b is provided on the bottom surface of the guide block 531 facing the pressure rod 42. The guide groove 531b is provided through the sliding direction of the pressure rod 42. The sliding groove 521 of the alignment block 52 is flush with the edge of the guide groove 531b, forming a smooth channel. This allows multiple pressure rods 42 to smoothly enter the sliding groove 521 under the guidance of the guide groove 531b, ensuring the alignment accuracy of the pressure rod 42 and the pressing station during the pressing process.

[0065] In this invention, during the downward pressing of the pressure rod 42 by the third cylinder 51, the alignment block 52 will experience a downward displacement. When the alignment block 52 moves downward and disengages from the guide block 531, the upward thrust generated by the pressure rod 42 during pressing will cause horizontal misalignment at the connection point of the alignment block 52. This can easily lead to a deviation in the downward force of the pressure rod 42, resulting in bending of the rod body and severely affecting the pressing accuracy. Therefore, the pressure table correction assembly 53 also includes a guide component. The guide component includes a pressure plate 533 located directly below the guide block 531 and a guide sleeve 534 fixedly mounted on the gantry frame 2. The inner slide rod of sleeve 534 extends into the drive area and connects to the pressure plate 533; wherein, the alignment block 52 passes through the guide block 531 and is fixed on the pressure plate 533, and the pressure plate 533 is provided with a strip groove 533a for sliding multiple pressure rods 42. When the third cylinder 51 drives the pressure rod 42 located at the pressing station to move downward through the alignment block 52, the pressure plate 533 moves downward synchronously with the alignment block 52, so that the alignment block 52 generates circumferential support during the downward movement, reducing offset and vibration, realizing the stability of the driving force of the pressure rod 42, and ensuring the alignment accuracy of the pressure rod 42 during the pressing process.

[0066] Since the required pressing heights for the components to be pressed on the multiple pressure rods 42 are different, in order to ensure that the components to be pressed can be installed in place, based on the above embodiment, as follows: Figure 9 and Figure 13As shown, a pressing depth detection component 8 is installed on the mounting frame 3, which can automatically adapt to the parts to be pressed at different heights and control the pressing pressure and stroke of the pressure plate 533 to achieve the predetermined pressing effect. Specifically, the pressing depth detection component 8 includes a displacement sensor 81 installed on the mounting frame 3 and a sensing plate 82 installed on the pressure plate 533 corresponding to the displacement sensor 81. The displacement sensor 81 is installed on the mounting frame 3 to detect the pressing depth of the parts to be pressed, while the sensing plate 82 is installed on the pressure plate 533 and cooperates with the displacement sensor 81 to receive and transmit the position information of the pressing height. When the parts to be pressed reach the set pressing depth, the displacement sensor 81 sends a signal, and the pressure plate 533 stops pressing to prevent over-pressing or damage. It can also provide feedback on the pressing distance after pressing is completed to facilitate the detection of whether the pressing is in place.

[0067] The present invention also provides a pressing method for a single-station multi-head pressing device, comprising the following steps:

[0068] Step 1: Place the workpiece in the pressing station of workbench 1;

[0069] Step 2: Start the first driving component 43 to drive the translational slide 41 to slide in the horizontal direction. When the pressure rod 42 corresponding to the first process moves to the top of the pressing station, the first driving component 43 stops moving. The pressing drive assembly 5 presses down the pressure rod 42 corresponding to the first process to realize the pressing of the part to be pressed in the first process.

[0070] Step 3: After the first pressing process is completed, the pressing drive assembly 5 drives the pressing rod 42 to return to its initial height. Step 2 is repeated to press the parts to be pressed on the pressing rod 42 of the next process until all pressing operations are completed.

[0071] This invention uses a first driving component 43 and a pressing driving assembly 5 to move and press down the pressure rod 42, thereby achieving automated pressing control of multiple processes at the same workstation. This reduces the need for manual operation, saves human resources, and ensures the pressing accuracy of the parts to be pressed in each process by precisely controlling the pressing position and pressure through the driving component. This improves the stability and reliability of pressing and thus improves the quality of the product.

[0072] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed.
