Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing technology, and in particular relates to an adjustable press device. Background Technology

[0002] In the field of machining, presses are widely used in processes such as riveting and stamping. Traditional presses typically employ a fixed structure with an adjustable pressure position, requiring manual repetitive movement of the workpiece to align with the pressure point. This method is not only inefficient but also prone to positioning deviations due to human factors, making it difficult to meet the requirements of high-precision machining.

[0003] To address this issue, some existing technologies have proposed presses with adjustable pressure positions. However, their adjustment mechanisms often rely on electric drives, resulting in complex structures and high costs, limiting their applicability in environments without power supply. Manual adjustment methods suffer from drawbacks such as operational lag and insufficient adjustment precision, affecting processing quality. For example, existing patent CN222968064U, "A Manual Riveting Gemstone Machine," proposes a semi-automatic riveting device that achieves automated riveting operations through the cooperation of an adjustment mechanism, a limiting mechanism, and a press. However, this solution is only suitable for single-station processing and cannot adapt to the needs of multi-station continuous operation, resulting in still low processing efficiency.

[0004] Therefore, there is an urgent need to develop a press with a simple structure, convenient adjustment, and suitable for multi-station processing, so as to improve the accuracy and efficiency of riveting operations, while reducing equipment costs and dependence on electric drive. Utility Model Content

[0005] The purpose of this invention is to solve the aforementioned problems in the prior art and to provide an adjustable press device.

[0006] The objective of this utility model is achieved through the following technical solution: An adjustable press device is mounted on a worktable. It includes a transfer mechanism that moves along the length of the worktable, and a riveting mechanism mounted on the transfer mechanism via a connecting plate. The riveting mechanism includes at least a column suspended vertically on the connecting plate, a connecting rod pivotally mounted on the top of the column, a pressure rod with its top end on the connecting rod, a pressure block located at the bottom of the pressure rod, and a guide seat suspended vertically on the column. The pressure rod passes through the guide seat, and a spring-loaded adjustment mechanism is fitted around the outer periphery of the pressure rod. The spring-loaded adjustment mechanism is located above the guide seat and includes at least a spring. The transfer mechanism moves the riveting mechanism horizontally to a processing position. The connecting rod rotates, causing the pressure rod to rise and fall relative to the guide seat, while simultaneously causing the spring in the spring-loaded adjustment mechanism to extend and retract, adjusting the pressure applied by the pressure block to the workpiece.

[0007] Preferably, a limiting hole is formed on the worktable along its length direction, and the transfer mechanism moves within the limiting range of the limiting hole along its setting direction; a scale line marking the moving distance is provided on the surface of the worktable, and the scale line is located on one side of the limiting hole.

[0008] Preferably, the transfer mechanism includes a guide rail disposed on the bottom surface of the worktable and a slider slidably disposed on the guide rail; there are two guide rails arranged in parallel; each guide rail corresponds to one slider; the connecting plate is fixed to the two sliders.

[0009] Preferably, the bottom end of the column is fixed to the connecting plate by bolts, and its top end passes through the limiting hole; and the top end of the column is formed with a notch for accommodating the pivot end of the connecting rod, and a pivot passes through the column and the connecting rod, so that the connecting rod can rotate relative to the column.

[0010] Preferably, the middle section of the connecting rod has a waist-shaped hole, and the top end of the pressure rod is pivotally connected to the waist-shaped hole; when the connecting rod is rotated, the top end of the pressure rod slides within the waist-shaped hole.

[0011] Preferably, the guide seat has a through hole for the pressure rod to pass through and a mounting hole for accommodating the column; a sleeve is embedded in the through hole, the sleeve is hollow T-shaped, the bottom end of the pressure rod and the pressure block pass through the sleeve and move relative to the sleeve; the bottom end of the spring abuts against the sleeve; a deformation notch is opened at the end of the guide seat away from the through hole, the notch communicates with the mounting hole; and the guide seat is provided with bolts to control the closing size of the notch and the mounting hole.

[0012] Preferably, the elastic adjustment mechanism includes the spring, a stop washer abutting against the top end of the spring, and a pin disposed on the upper surface of the stop washer; the pin passes through the pressure rod to limit the compression position of the spring.

[0013] Preferably, the pressure rod is provided with a set of through holes to facilitate the insertion of the pin, so as to adjust the height of the pressure block and the spring force.

[0014] Preferably, the worktable is mounted on a support; at least two sets of lasers are mounted on the support; the moving position of the transfer mechanism is monitored by the lasers.

[0015] The advantages of this utility model's technical solution are mainly reflected in: The riveting mechanism is moved on the worktable by the transfer device to meet the processing needs of multiple stations. This allows other work to be loaded while one station is riveting, or to meet the processing needs of multiple points on the same workpiece, thereby improving processing efficiency and ensuring processing quality. The pressure is adjusted by using springs and stop shims on the elastic adjustment mechanism to meet the processing requirements of different heights and pressures, thereby improving the flexibility of use; A laser is installed on the transfer device to detect the movement position of the transfer mechanism, ensuring the accuracy of the pressure bar movement and processing position.

[0017] The purpose, advantages, and features of this utility model will be illustrated and explained through the following non-limiting description of preferred embodiments. These embodiments are merely typical examples of applying the technical solutions of this utility model, and all technical solutions formed by equivalent substitutions or equivalent transformations fall within the scope of protection claimed by this utility model.

[0018] In the description of the solution, it should be noted that the terms "center," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience and simplification of description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Also, in the description of the solution, with the operator as a reference, the direction closer to the operator is the proximal end, and the direction farther from the operator is the distal end.

[0019] like Figure 1As shown, this utility model discloses an adjustable press device, mounted on a worktable 1. The worktable 1 has a limiting hole 10 formed along its length, preferably oblong in shape. A transfer mechanism 2 moves within the limiting range of the limiting hole 10 along its direction. Further, the worktable 1 has a scale line 12, which determines the moving distance of the transfer mechanism 2. Even further, the worktable 1 is mounted on a support 11, which has at least two sets of lasers 101; the lasers 101 monitor the moving position of the transfer mechanism 2. The number of lasers 101 can be adjusted according to usage requirements. When there are two lasers 101, the transfer mechanism 2 moves to the first laser 101 and stops, performing a riveting operation at that position; simultaneously, the workpiece to be riveted is loaded at the position of the second laser 101. After the workpiece at the first position is riveted, the transfer mechanism 2 moves to the position of the second laser 101 and stops, and performs the riveting operation at the second laser 101. At the same time, the workpiece to be riveted is loaded at the position of the first laser 101. It can be seen that setting the laser 101 on the bracket 11 can determine the processing and transfer endpoint position, thereby improving processing efficiency.

[0020] Specifically, an adjustable press device includes a transfer mechanism 2 that moves along the length of the worktable 1, and a riveting mechanism 3 mounted on the transfer mechanism 2 via a connecting plate 203. The transfer mechanism 2 drives the riveting mechanism 3 to move horizontally to the processing position, that is, by moving the riveting mechanism 3 through the transfer mechanism 2, the processing requirements of different positions can be met, the number of riveting mechanisms 3 can be reduced, and work efficiency and processing quality can be guaranteed at the same time.

[0021] like Figure 2 As shown, the transfer mechanism 2 includes a guide rail 21 disposed on the bottom surface of the worktable 1 and a slider 22 slidably disposed on the guide rail 21. There are two guide rails 21 arranged in parallel; each guide rail 21 corresponds to one slider 22; the connecting plate 203 is fixed to the two sliders 22. The guide rails 21 are disposed on both sides of the limiting hole 10. The sliders 22 drive the connecting plate 203 and the transfer mechanism 2 to slide within the limiting range of the limiting hole 10, thereby performing riveting processing on workpieces at different positions.

[0022] like Figure 1 As shown, the riveting mechanism 3 includes at least a column 31 vertically mounted on the connecting plate 203, a connecting rod 32 pivotally mounted on the top of the column 31, a pressure rod 33 with its top end mounted on the connecting rod 32, a pressure block 34 located at the bottom end of the pressure rod 33, and a guide seat 35 vertically mounted on the column 31.

[0023] The bottom end of the column 31 is fixed to the connecting plate 203 by bolts, and its top end passes through the limiting hole 10. That is, the width of the limiting hole 10 is approximately equal to the diameter of the column 31. Furthermore, the top end of the column 31 has a notch for accommodating the pivot end of the connecting rod 32, and a pivot passes through the column 31 and the connecting rod 32, allowing the connecting rod 32 to rotate relative to the column 31. Thus, the transfer mechanism 2 can move the column 31 and the connecting rod 32 along the direction of the limiting hole 10. Further, the middle section of the connecting rod 32 has a waist-shaped hole 320, and the top end of the pressure rod 33 is pivotally connected to the waist-shaped hole 320; when the connecting rod 32 is rotated, the top end of the pressure rod 33 slides within the waist-shaped hole 320. The free end of the connecting rod 32 is provided with a spherical handle. By applying force to the spherical handle, the connecting rod 32 rotates, thereby driving the pressure rod 33 to rise and fall. During the rising and falling process, due to the restriction of the guide seat 35, the top end of the pressure rod 33 slides within the oblong hole 320, while ensuring the verticality of the pressure rod 33. In addition, the spherical handle is more ergonomic and convenient to operate during use.

[0024] Furthermore, the pressure rod 33 penetrates the guide seat 35, meaning that the guide seat 35 has a through hole for the pressure rod 33 to pass through; a sleeve 4 is embedded in the through hole, and the sleeve 4 is hollow in the shape of a T. The bottom end of the pressure rod 33 and the pressure block 34 penetrate the sleeve 4 and move relative to the sleeve 4.

[0025] A spring force adjustment mechanism 36 is sleeved around the outer periphery of the pressure rod 33, and the spring force adjustment mechanism 36 is located above the guide seat 35. The spring force adjustment mechanism 36 includes at least a spring 361, the bottom end of which abuts against the sleeve 4. Further, the spring force adjustment mechanism 36 also includes a stop washer 362 that abuts against the top end of the spring 361, and a pin 363 disposed on the upper surface of the stop washer 362. The pin 363 passes through the pressure rod 33 to limit the compression position of the spring 361. The pressure rod 33 is provided with a set of through holes for easy insertion of the pin 363, so as to adjust the height of the pressure block 34 and the spring force. By providing a set of through holes on the pressure rod for easy pin insertion, the initial height and elastic force of the spring can be adjusted in a timely manner according to usage requirements.

[0026] The rotation of the connecting rod 32 causes the pressure rod 33 to rise and fall relative to the guide seat 35, and at the same time causes the spring 361 in the elasticity adjustment mechanism 36 to extend and retract, adjusting the pressure applied by the pressure block 34 to the workpiece.

[0027] Furthermore, the guide seat 35 also has a mounting hole for accommodating the column 31. A deformation notch is provided at the end of the guide seat 35 away from the through hole, and this notch communicates with the mounting hole; and a bolt is provided on the guide seat 35 to control the closed size of the notch and the mounting hole. The notch makes the mounting hole an open hole, accommodating columns of different diameters, meeting different assembly requirements, and improving equipment flexibility.

[0028] This utility model has many other embodiments. All technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of this utility model.
