Description

Technical Field

[0001] This utility model belongs to the field of mechanical assembly technology, and in particular relates to a machine tool support assembly device. Background Technology

[0002] Machine tool support components, as essential basic components of machine tool equipment, function to provide stable support for the machine tool lead screw, reduce vibration of long-distance lead screws during operation, and maintain their accuracy. In existing technology, conventional machine tools are usually equipped with multiple independent support components to form a distributed support system.

[0003] The support components of this machine tool generally adopt a multi-component assembly structure, such as Figure 1 As shown, the machine tool support generally includes core components such as part A 101, part B 102, spring C 103, part D 104, locating post E 105, base F 106, and nut G 107. Part A 101 and part B 102 form a sleeve structure. Spring C 103 is installed inside part B 102 and sleeved on the outer edge of locating post E 105. Locating post E 105 is locked to base F 106 by nut G 107. Part D 104 is sleeved on the outside of part B 102, and the bottom of part D 104 is connected to base F 106. Connecting ears H108 are provided at both ends of part D 104 to form assembly interfaces.

[0004] Before the machine tool support component is assembled, spring C 103 is in an extended state, and positioning column E 105 has not yet contacted base F 106 and nut G 107. In the current assembly process, U-shaped clamping devices are generally used to temporarily fix the spring assembly on the machine tool support component. This process has the following significant defects: (1) There is a mechanical imbalance between the effective clamping area of ​​the U-shaped clamp and the spring preload. When the spring preload exceeds the critical value, the clamping interface is prone to slippage and detachment; (2) The assembly operation requires two people to work together, one person to maintain the positioning of the component and the other person to tighten it, resulting in low work efficiency and the risk of coordination error; (3) When the clamp fails suddenly, the elastic potential energy stored in the spring is released instantaneously, causing the component to be ejected at high speed, which poses a serious risk of personal injury; (4) Due to the limitation of the clamp structure, it is difficult to achieve precise alignment control in the assembly process, which affects the coaxiality accuracy of the final component. Utility Model Content

[0005] The purpose of this utility model is to provide a machine tool support assembly device to solve the problems of low assembly efficiency and operational risks in the assembly process of existing machine tool support components.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A machine tool support assembly device, comprising:

[0008] Support base plate;

[0009] The support column is provided in four parts, which are vertically installed at the four corners of the top of the support base plate.

[0010] The base is located above the supporting base plate. The four corners of the bottom surface of the base are provided with through holes that cooperate with the column. The top of the base is provided with two pads, and an operating cavity is formed between the two pads. An operating hole two is opened on the top surface of the base corresponding to the position of the operating cavity. The operating cavity and the operating hole two are connected.

[0011] A top cover plate is located above the base. The upper end of the column is connected to the top cover plate after passing through a hole. A threaded hole is opened in the center of the top of the top cover plate. A stud is threaded into the threaded hole. A crank handle is provided on the top of the stud. A pressure plate is provided at the bottom of the stud.

[0012] Furthermore, the support base plate is provided with feet at all four corners of its bottom surface.

[0013] Furthermore, the foot includes a fixing screw and a support foot threaded to the lower end of the fixing screw, and the top of the fixing screw is connected to the support base plate.

[0014] Furthermore, the bottom surface of the support foot is provided with an anti-slip pad.

[0015] Furthermore, the pad is fixed to the top surface of the base by bolt connection.

[0016] Furthermore, each of the four corners of the top surface of the top cover plate is provided with a lifting ring.

[0017] Furthermore, the crank handle includes a connecting plate and a hand handle, one end of the connecting plate is connected to a stud, and the other end of the connecting plate is connected to the hand handle.

[0018] Furthermore, the connecting plate and the hand handle are vertically connected in an L-shape.

[0022] Furthermore, the handle is provided with an anti-slip sleeve.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. This utility model provides a machine tool support assembly device, which includes a base and two pads. The pads support the connecting ears H at both ends of part D in the machine tool support assembly and work with a pressure plate to achieve overall clamping of the components. The assembly process is as follows: First, after the initial assembly of parts A, B, spring C, and positioning post E of the machine tool support, they are placed into the device, so that the connecting ears H of part D are accurately positioned on the two pads. Second, the crank handle drives the stud to rotate, and the pressure plate is pressed downward through the threaded transmission. The pressure is transmitted to part B and spring C in sequence, forcing the spring to compress to a preset deformation. Third, during the compression of spring C, the positioning post E moves automatically downward along the inner cavity of part A under the action of gravity until its end passes through the assembly hole of the base F. Finally, when the spring compression reaches the process requirements, the nut G is immediately tightened to complete the rigid locking of the positioning post E and the base F, forming a stable preload retention structure.

[0025] 2. This utility model has the following advantages through the linkage design of the pad, pressure plate and stud: First, a single crank rotation synchronously completes spring compression, positioning post guidance and assembly space maintenance, allowing a single person to smoothly complete the entire process; Second, the threaded transmission mechanism linearly converts the operator's input torque into controllable pressure, avoiding component rebound caused by sudden changes in preload in traditional U-clamping; Third, the surface contact constraint system formed by the pressure plate and pad can suppress part displacement throughout the spring compression process, completely eliminating the risk of ejection during assembly.

[0026] 3. The machine tool support assembly device provided by this utility model can not only reduce manufacturing costs and improve assembly efficiency compared with traditional processes, but also completely avoid the safety hazards that exist in the process of multi-person collaboration, and has significant industrial application value.

Detailed Implementation

[0036] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements 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.

[0038] Machine tool support components, as essential basic components of machine tool equipment, function to provide stable support and precise positioning for the machine tool body. In existing technologies, conventional machine tools typically employ multiple independent support components to form a distributed support system.

[0039] The support components of this machine tool generally adopt a multi-component assembly structure, such as Figure 1As shown, the machine tool support generally includes core components such as part A 101, part B 102, spring C 103, part D 104, locating post E 105, base F 106, and nut G 107. Part A 101 and part B 102 form a sleeve structure. Part D 104 is sleeved on the outside of part B 102, and its bottom is connected to base F 106. Spring C 103 is installed inside part B 102 and sleeved on the outer edge of locating post E 105. Locating post E 105 is locked to base F 106 by nut G 107. Connecting ears H108 are provided at both ends of part D 104 to form assembly interfaces.

[0040] Before the machine tool support component is assembled, spring C 103 is in an extended state, and positioning column E 105 has not yet contacted base F 106 and nut G 107. In the current assembly process, U-shaped clamping devices are generally used to temporarily fix the spring assembly on the machine tool support component. This process has the following significant defects: (1) There is a mechanical imbalance between the effective clamping area of ​​the U-shaped clamp and the spring preload. When the spring preload exceeds the critical value, the clamping interface is prone to slippage and detachment; (2) The assembly operation requires two people to work together, one person to maintain the positioning of the component and the other person to tighten it, resulting in low work efficiency and the risk of coordination error; (3) When the clamp fails suddenly, the elastic potential energy stored in the spring is released instantaneously, causing the component to be ejected at high speed, which poses a serious risk of personal injury; (4) Due to the limitation of the clamp structure, it is difficult to achieve precise alignment control in the assembly process, which affects the coaxiality accuracy of the final component.

[0041] like Figures 1 to 7 As shown, a machine tool support assembly device includes a support base plate 12, a column 13, a base 6, and a top cover plate 2.

[0042] Specifically, there are four columns 13, which are vertically installed at the four corners of the top of the support base plate 12; the four columns 13 are fixedly installed at the four corners of the top of the support base plate 12.

[0043] The base 6 is located above the support base plate 12. The four corners of the bottom surface of the base 6 are provided with through holes 61 that cooperate with the column 13. The column 13 passes through the through holes 61. Specifically, the column 13 is fixedly installed in the through holes 61.

[0044] The top of the base 6 is provided with two pads 7, and an operating cavity 71 is formed between the two pads 7. An operating hole 62 is opened on the top surface of the base 6 at the position corresponding to the operating cavity 71, and the operating cavity 71 is connected to the operating hole 62.

[0045] The top cover plate 2 is located above the base 6. The upper end of the column 13 passes through the through hole 61 and is fixedly connected to the top cover plate 2. A threaded hole is opened in the center of the top of the top cover plate 2. A stud 4 is threadedly connected in the threaded hole. A crank 1 is provided on the top of the stud 4. A pressure plate 5 is provided at the bottom of the stud 4.

[0046] The assembly process for the machine tool support components in this machine tool support assembly device is as follows:

[0047] Note: This machine tool support generally includes core components such as part A 101, part B 102, spring C 103, part D 104, locating post E 105, base F 106, and nut G 107. Part A 101 and part B 102 form a sleeve structure. Spring C 103 is installed inside part B 102 and sleeved on the outer edge of locating post E 105. Locating post E 105 is locked to base F 106 via nut G 107. Part D 104 is sleeved on the outside of part B 102, and the bottom of part D 104 is connected to base F 106. Connecting ears H 108 are provided at both ends of part D 104 to form assembly interfaces.

[0048] The assembly process is as follows: First, after the initial assembly of parts A, B, spring C, and positioning pin E of the machine tool support component, place them into the machine tool support assembly device, so that the connecting lug H of part D is accurately positioned on the two pads 7; Second, turn the crank handle 1 to drive the stud 4 to rotate, and through the threaded transmission, the pressure plate 5 applies downward pressure, which is transmitted to part B and spring C in sequence, forcing the spring to compress to the preset deformation; Third, during the compression of spring C, the positioning pin E moves automatically downward along the inner cavity of part A under the action of gravity until its end passes through the assembly hole of the base F; Finally, when the spring compression reaches the process requirements, immediately tighten the nut G to complete the rigid locking of the positioning pin E and the base F, forming a stable preload retention structure.

[0049] like Figures 2 to 6 As shown, in some embodiments of this utility model, the pressure plate 5 has an annular protrusion 51 that protrudes upward from the center of its top, and the height of the annular protrusion 51 is 20-30mm. The bottom of the stud 4 has a 30-60mm unthreaded area, and the unthreaded area of ​​the stud 4 is rotatably mounted in the annular protrusion 51.

[0050] Specifically, since the bottom of the stud 4 is rotatably installed in the annular protrusion 51, the pressure plate 5 does not rotate with the stud 4 when the stud 4 rotates, thus avoiding displacement or loosening caused by the rotation of the pressure plate 5 and ensuring the stability of the position of the pressed machine tool support. In addition, since the stud 4 can rotate independently, there is no need to overcome the resistance of the pressure plate 5, making it easier to turn the crank handle 1 and improving the adjustment efficiency.

[0051] like Figures 2 to 6As shown, in some embodiments of this utility model, the column 13 can be fixed in the through hole 61 by welding or screw connection.

[0052] Specifically, the column 13 can be fixed in the through hole 61 by screws. A threaded hole connected to the through hole 61 is opened on the base 6 near the through hole 61. A screw is installed in the threaded hole. The screw passes through the threaded hole and is screwed into the column 13 in the through hole 61, so that the column 13 is fixed in the through hole 61.

[0053] During actual installation, first place the column 13 into the through hole 61, then screw the screw into the threaded hole and through the through hole 61, and finally tighten it inside the column 13, thereby achieving reliable fixation of the column 13 in the through hole 61.

[0054] This detachable connection method facilitates the assembly of the column 13 and the base 6. At the same time, when the column 13 or the base 6 is damaged, the damaged parts can be disassembled and replaced individually, avoiding the scrapping of the entire structure and reducing maintenance costs.

[0055] like Figures 2 to 6 As shown, in some embodiments of this utility model, the four corners of the bottom surface of the support base plate 12 are provided with feet 8; each foot 8 consists of a fixing screw 81 and a support foot 82, wherein the top of the fixing screw 81 is fixedly connected to the support base plate 12, and its lower outer end is connected to the support foot 82 by a thread. The bottom surface of the support foot 82 is also provided with an anti-slip pad;

[0056] This structure has the following advantages:

[0057] First, the use of a threaded connection structure between the fixing screw 81 and the support foot 82 allows the support foot 82 to be height-adjusted on the fixing screw 81, which facilitates equipment leveling and adapts to different ground conditions.

[0058] Secondly, the four-point symmetrical layout (i.e., the arrangement of four feet) combined with the anti-slip pad design effectively improves equipment stability and prevents slippage. The anti-slip pad also has shock absorption and noise reduction functions.

[0059] Third, the detachable foot assembly simplifies the installation and maintenance process, and the separate structure of the fixing screw 81 and the support foot 82 facilitates the replacement and maintenance of individual components.

[0060] Fourth, by setting up support points (i.e., foot 8) at the corners, the equipment load can be effectively transferred to the ground, avoiding stress concentration in the middle area of ​​the support base plate 12;

[0061] Fifth, the metal-to-metal contact at the threaded connection, combined with the cushioning protection of the anti-slip pad, ensures structural strength while reducing thread wear caused by vibration.

[0062] like Figures 2 to 6 As shown, in some embodiments of this utility model, the pad 7 is fixed to the top surface of the base 6 by bolt connection;

[0063] This detachable connection method allows for flexible adjustment of the spacing between the two pads 7 according to the size and specifications of the machine tool support. In other words, multiple threaded holes at different positions are provided on the base 6 to change the position of the pads 7 on the base 6.

[0064] Specifically, by adjusting the distance between the two pads 7, it can be compatible with machine tool support components of different specifications, effectively improving the equipment's adaptability to different workpieces. In addition, the bolt connection method allows the pads 7 to be disassembled and replaced individually. When wear occurs or upgrades are needed, maintenance operations can be performed without disassembling the entire base system, significantly reducing maintenance costs and downtime.

[0065] like Figures 2 to 6 As shown, in some embodiments of this utility model, lifting rings 3 are provided at the four corners of the top surface of the top cover plate 2;

[0066] The device is equipped with lifting rings 3, which are designed for lifting operations of machine tool support assembly devices, enabling smooth transfer and flexible relocation of the device between different workstations.

[0067] Specifically, by symmetrically distributing four lifting rings 3 at the four corners of the top cover plate 2, which is rectangular in shape, the distribution of the four lifting rings 3 conforms to the principle of mechanical balance, ensuring uniform force distribution during the lifting process. The four-point lifting design effectively prevents the device from tilting or rotating during lifting, ensuring operational safety. The standardized lifting interface enables quick hooking operations, significantly improving equipment transfer efficiency. In addition, this design allows the use of lifting equipment of different specifications, making it suitable for various operating environments such as workshops and installation sites.

[0068] like Figures 2 to 6 As shown, in some embodiments of this utility model, the crank handle 1 is composed of a connecting plate 14 and a hand handle 15. Specifically, the connecting plate 14 and the hand handle 15 are vertically connected to form an L-shaped structure.

[0069] One end of the connecting plate 14 is provided with a mounting hole. The stud 4 passes through the mounting hole and is connected to the connecting plate 14 and the stud 4 by thread. To ensure the reliability of the connection, two fastening nuts 41 are provided on the outside of the stud 4 to lock and fix the connecting plate 14.

[0070] The handle 15 is covered with an anti-slip sleeve, which significantly improves grip friction and enhances the safety and comfort of manual operation.

[0071] The crank handle 1 is designed to form a lever structure by vertically connecting the connecting plate 14 and the hand handle 15, which facilitates torque transmission and saves installation space. The connection between the connecting plate 14 and the stud 4 enables precise alignment and adjustable fixation of the stud 4, ensuring connection stability. In addition, the double locking mechanism of double fastening nuts 41 effectively prevents loosening caused by vibration.

[0072] The detachable connection design of the crank handle 1 and stud 4 facilitates maintenance, replacement, and size adjustment.

[0073] This utility model provides a machine tool support assembly device. Compared with traditional processes, this device can not only reduce manufacturing costs and improve assembly efficiency, but also completely avoid the safety hazards that exist in the process of multiple people working together, and has significant industrial application value.
