Abstract
Description
Technical Field
[0001] This utility model relates to the field of press fitting machine technology, and in particular to a workpiece fastening structure for a press fitting machine. Background Technology
[0002] Press fitting machines are used to assemble or fix workpieces in a designated position by pressure. They are commonly used for component installation in industries such as automobiles, electronics, and machinery. Traditional fastening structures usually rely on mechanical clamps or fixing devices, but these methods are often not stable or flexible enough under the requirements of high-precision and high-efficiency production, and are prone to workpiece deformation or damage. Therefore, developing more precise and reliable fastening structures has become an important issue for improving production efficiency and product quality.
[0003] However, in actual use, the following shortcomings still exist. For example, the workpiece fastening structure used in existing press-fitting machines cannot stably fix the workpiece for press-fitting. If the workpiece moves or vibrates during the press-fitting process, it may lead to inaccurate press-fitting position, thereby affecting the overall quality and performance of the product. Since the position of the workpiece needs to be manually adjusted, this will increase the operation time and reduce production efficiency. The instability of the workpiece may lead to excessive wear of the press-fitting equipment, thereby shortening its service life. The instability of the workpiece may lead to accidents during operation, such as the workpiece flying out, which increases the safety hazards for operators.
[0004] Therefore, this utility model proposes a workpiece fastening structure for a press fitting machine to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a workpiece fastening structure for a press fitting machine.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a workpiece fastening structure for a press fitting machine, comprising:
[0007] Cabinet;
[0008] A press-fitting assembly is placed inside the cabinet. The press-fitting assembly includes a hydraulic push rod installed on the top of the cabinet. The output end of the hydraulic push rod is fixed with a mounting base. A support base is fixed inside the cabinet on the side near the hydraulic push rod. The output end of the hydraulic push rod is slidably connected in the support base. A display screen is installed on one side of the cabinet. A control button is provided on the side of the cabinet near the display screen. A start button is provided on the cabinet.
[0009] A fastening assembly is placed on a support base. The fastening assembly includes a first support plate fixed on the support base, a connecting block fixed on the first support plate, a first electric push rod mounted on the first support plate, a pressure plate rotatably connected to the output end of the first electric push rod, a support block fixed on the side of the first support plate near the pressure plate, a rotating block rotatably connected to the support block, and the pressure plate rotatably connected to the rotating block.
[0010] Furthermore, an emergency stop button is provided on the cabinet.
[0011] The beneficial effects of adopting the above-mentioned further solutions are as follows: The emergency stop button is a key safety control device designed to ensure that in the event of an abnormal situation or when the operator needs to stop the device immediately during equipment operation, the power supply can be quickly disconnected and all working actions can be stopped. It provides the operator with a means to stop operation in an emergency, avoiding safety hazards caused by equipment failure or operational errors.
[0012] Furthermore, a pressure block is fixed on the side of the pressure plate away from the output end of the first electric push rod.
[0013] The beneficial effects of adopting the above-mentioned further solution are: the pressure block is used to increase the contact area or pressure between the pressure plate and the workpiece to ensure that sufficient clamping force or pressing force is generated between the pressure plate and the workpiece. It can help to achieve uniform pressure distribution and ensure that the workpiece is stable and not easily displaced.
[0014] Furthermore, a support component is provided on the side of the support base near the fastening component. The support component includes a limiting block fixed on the support base near the fastening component, and a second electric push rod is installed on the limiting block.
[0015] The beneficial effects of adopting the above-mentioned further solution are: the support assembly, through the coordinated work of the limit block and the second electric push rod, provides precise control and restriction of the position of the relevant components. The main function of the limit block is to restrict and position, ensuring that the components are stably fixed during fastening or processing. The second electric push rod provides electric adjustment capability for this process, realizing high-precision and automated control.
[0016] Furthermore, a slider is fixed to the output end of the second electric push rod, and a groove is provided on the limiting block, with the slider slidably connected in the groove.
[0017] The beneficial effect of adopting the above-mentioned further solution is that the groove restricts the sliding trajectory of the slider within the limit block, thereby preventing excessive movement or irregular movement of the slider.
[0018] Furthermore, a second support plate is fixed to the top of the slider, a drive motor is mounted on the second support plate, a bidirectional lead screw is fixed to the output end of the drive motor, and a first rotating rod is threaded onto the bidirectional lead screw.
[0019] The beneficial effect of adopting the above-mentioned further solution is that the first rotating rod receives power from the transmission motor and moves by means of a threaded connection with the bidirectional lead screw, and then transmits this power to other mechanical components. Depending on the position and angle of the rotating rod, complex mechanical actions can be realized.
[0020] Furthermore, a second rotating rod is rotatably connected to the first rotating rod, the other end of the second rotating rod is rotatably connected to the second support plate, and a rubber pad is rotatably connected to the end of the first rotating rod away from the bidirectional lead screw.
[0021] The beneficial effects of adopting the above-mentioned further solution are: by connecting the first rotating rod and the second rotating rod and rotatably supporting them on the second support plate, the system is provided with greater flexibility and adjustability. The addition of the rubber pad enhances the vibration reduction performance of the system, enabling the transmission system to operate stably in environments with high precision requirements.
[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0023] In this invention, firstly, the workpiece to be pressed is placed on the connecting block. Then, the first electric push rod starts working, pushing the pressure plate to rotate. The output end of the electric push rod is connected to the pressure plate by rotation, achieving precise control. Since the pressure plate is connected to the support block through the rotating block, the pressure plate can perform accurate rotation under the action of the rotating block, thereby applying the necessary pressure to ensure the workpiece is fastened. The hydraulic push rod is installed on the top of the cabinet and is slidably connected to the support base. The power is turned on by the control button, and the hydraulic push rod is started by the start button. Under the action of the hydraulic system, the thrust of the hydraulic push rod output end is transmitted to the mounting base, pushing the pressing assembly to slide along the support base to achieve the pressing action. At this time, the linear thrust generated by the hydraulic push rod enables the pressing assembly to apply pressure precisely to meet the fastening requirements of the workpiece, thereby achieving stable fixing of the workpiece for pressing.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a workpiece fastening structure for a press fitting machine, comprising:
[0035] Cabinet 1;
[0036] Pressing assembly 2 is placed inside cabinet 1. Pressing assembly 2 includes a hydraulic push rod 21 installed on the top of cabinet 1. The output end of hydraulic push rod 21 is fixed with mounting base 22. A support base 23 is fixed inside cabinet 1 on the side near hydraulic push rod 21. The output end of hydraulic push rod 21 is slidably connected in support base 23. A display screen 24 is installed on one side of cabinet 1. A control button 25 is provided on the side of cabinet 1 near display screen 24. A start button 26 is provided on cabinet 1.
[0037] Fastening assembly 3 is placed on support base 23. Fastening assembly 3 includes a first support plate 31 fixed to support base 23, a connecting block 32 fixed to the first support plate 31, a first electric push rod 33 mounted on the first support plate 31, and a pressure plate 34 rotatably connected to the output end of the first electric push rod 33. A support block 35 is fixed to the side of the first support plate 31 near the pressure plate 34, and a rotating block 36 is rotatably connected to the support block 35. The pressure plate 34 is rotatably connected to the rotating block 36. First, the workpiece to be pressed is placed on the connecting block 32. Then, the first electric push rod 33 starts working, pushing the pressure plate 34 to rotate. The output end of the electric push rod is rotatably connected to the pressure plate 34, achieving precise control. Since the pressure plate 34 is connected to the support block 35 through the rotating block 36, the pressure plate 34 can perform accurate rotation under the action of the rotating block 36, thereby applying the necessary pressure to ensure the fastening of the workpiece. Hydraulic push rod 21 is installed on the top of cabinet 1 and is slidably connected to support base 23. Power is turned on by control button 25, and hydraulic push rod 21 is activated by start button 26. Under the action of the hydraulic system, the thrust at the output end of hydraulic push rod 21 is transmitted to mounting base 22, pushing pressing assembly 2 to slide along support base 23 to realize pressing action. At this time, the linear thrust generated by hydraulic push rod 21 enables pressing assembly 2 to apply pressure precisely to meet the fastening requirements of workpiece, thereby realizing stable fixing of workpiece for pressing. The user monitors the entire working process through display screen 24 on cabinet 1. Display screen 24 provides real-time feedback on system status, helping operators adjust and control various parameters. At the same time, the entire system is activated by start button 26, and operators can start hydraulic push rod 21 and electric push rod for operation. Display screen 24 can also display important parameters such as current pressure and displacement for monitoring and adjustment of working status.
[0038] The above solutions also have the problem of failing to provide stable support for the workpiece during press-fitting operations, such as... Figure 1 As shown: Cabinet 1 is equipped with an emergency stop button 27. The emergency stop button 27 is a key safety control device designed to ensure that if an abnormal situation occurs during equipment operation or if the operator needs to stop the device immediately, the power supply can be quickly disconnected and all working actions can be stopped. It provides the operator with an emergency means to stop the operation and avoid safety hazards caused by equipment failure or operational errors.
[0039] like Figure 2 - Figure 3 As shown, a pressure block 37 is fixed on the side of the pressure plate 34 away from the output end of the first electric push rod 33. The pressure block 37 is used to increase the contact area or pressure between the pressure plate 34 and the workpiece to be processed, so as to ensure that sufficient clamping force or pressing force is generated between the pressure plate 34 and the workpiece. It can help to achieve uniform pressure distribution and ensure that the workpiece is stable and not easily displaced.
[0040] like Figure 1 - Figure 2 as well as Figure 4 As shown, a support component 4 is provided on the support base 23 near the fastening component 3. The support component 4 includes a limiting block 41 fixed on the support base 23 near the fastening component 3. A second electric push rod 42 is installed on the limiting block 41. The support component 4, through the coordinated operation of the limiting block 41 and the second electric push rod 42, provides precise control and restriction of the position of related components. The main function of the limiting block 41 is to restrict and position, ensuring that the components are stably fixed during fastening or processing. The second electric push rod 42 provides electric adjustment capability for this process, achieving high-precision and automated control. A slider 43 is fixed to the output end of the second electric push rod 42. A groove 44 is provided on the limiting block 41, and the slider 43 is slidably connected in the groove 44. The groove 44 restricts the sliding trajectory of the slider 43 in the limiting block 41, thereby preventing excessive movement or irregular movement of the slider 43. A second support plate 45 is fixed to the top of the slider 43. A drive motor 46 is mounted on plate 45. A bidirectional lead screw 47 is fixed to the output end of the drive motor 46. A first rotating rod 48 is threadedly connected to the bidirectional lead screw 47. The first rotating rod 48 receives power from the drive motor 46 and moves through the threaded connection with the bidirectional lead screw 47, thereby transmitting this power to other mechanical components. Complex mechanical actions can be achieved according to the position and angle of the rotating rod. A second rotating rod 49 is rotatably connected to the first rotating rod 48. The other end of the second rotating rod 49 is rotatably connected to the second support plate 45. A rubber pad 410 is rotatably connected to the end of the first rotating rod 48 away from the bidirectional lead screw 47. By connecting the first rotating rod 48 and the second rotating rod 49 and rotatably supporting them on the second support plate 45, the system is provided with greater flexibility and adjustability. The addition of the rubber pad 410 enhances the vibration reduction performance of the system, enabling the transmission system to operate stably in environments with high precision requirements.
[0041] like Figure 1 - Figure 4As shown, firstly, the workpiece to be pressed is placed on the connecting block 32. Then, the first electric push rod 33 starts working, pushing the pressure plate 34 to rotate. The output end of the electric push rod is rotatably connected to the pressure plate 34 to achieve precise control. Since the pressure plate 34 is connected to the support block 35 through the rotating block 36, the pressure plate 34 can perform accurate rotation under the action of the rotating block 36, thereby applying the necessary pressure to ensure the workpiece is secure. When the second electric push rod 42 works, it pushes the slider 43 to slide in the slide groove 44, thereby driving the second support plate 45 to move along the slide groove 44. The drive motor 46 drives the bidirectional lead screw 47 to rotate, driving the first rotating rod 48 to rotate. Then, through the rotatable connection with the second rotating rod 49, the position of the second support plate 45 is adjusted, so that it can support the workpiece to be pressed. The hydraulic push rod 21 is installed on the top of the cabinet 1 and is slidably connected to the support base 23. The power is turned on by the control button 25, and the hydraulic push rod 21 is started by the start button 26. Under the action of the hydraulic system... The thrust from the output end of the hydraulic push rod 21 is transmitted to the mounting base 22, pushing the pressing assembly 2 to slide along the support base 23 to achieve the pressing action. At this time, the linear thrust generated by the hydraulic push rod 21 enables the pressing assembly 2 to apply pressure precisely to meet the fastening requirements of the workpiece, thereby achieving stable fixing of the workpiece for pressing. The user monitors the entire working process through the display screen 24 on the cabinet 1. The display screen 24 provides real-time feedback on the system status, helping the operator to adjust and control various parameters. At the same time, the entire system can be activated by the start button 26, allowing the operator to start the hydraulic push rod 21 and the electric push rod for operation. The display screen 24 can also display important parameters such as current pressure and displacement for monitoring and adjustment of the working status. The emergency stop button 27 is a key safety control device designed to ensure that if an abnormal situation occurs during equipment operation or the operator needs to stop the device immediately, the power supply can be quickly disconnected and all working actions can be stopped. It provides the operator with an emergency stop operation method to avoid safety hazards caused by equipment failure or operational errors.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
