Description

Technical Field

[0001] This utility model belongs to the field of machine tool component support technology, specifically relating to a shockproof and stable support structure for machine tool functional components. Background Technology

[0002] In modern manufacturing equipment, the functional components of machine tools (such as control boxes and operation panels) serve as key nodes in human-machine interaction. Their stability, adjustability, and vibration resistance are crucial for operational safety and accuracy. Especially in medium and large-sized CNC machine tools or machining scenarios requiring high precision, machine tool control boxes typically need to be adjustable in terms of rotation and height to accommodate the needs of different operators. However, most existing structures only achieve adjustment through simple bolt fastening, pin limiting, or gas spring support, resulting in limited structural stability and angle fixation performance.

[0003] Common problems in existing technologies include: the machine tool control box is prone to loosening at the angle under vibration, and cannot maintain stability after the rotation angle is adjusted; the lack of good coordination between the shock absorption structure and the lifting structure leads to a decrease in the shock absorption effect after height adjustment; the limit fixing structure often fails after multiple adjustments due to wear or insufficient fitting precision, which in turn causes the control box to vibrate or even rotate out of control during operation. In addition, the lack of stable and synchronized structural coordination when operators adjust the angle or height of the control box easily leads to angle errors or difficulty in adjustment, affecting overall processing efficiency and safety. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a shockproof and stable support structure for machine tool functional components. This structure can achieve a stable structure, precise height and angle adjustment, good shock absorption function, and long-term rotational positioning stability, thereby solving problems such as unstable support, weak positioning, inconsistent shock absorption, and inconvenient adjustment operation in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A shockproof and stable support structure for a machine tool functional component includes a machine body, on one side of the front surface of the machine body a threaded rod is vertically rotatably mounted; a lifting sleeve is screwed onto the surface of the threaded rod, and a machine tool control box is rotatably mounted on the surface of the lifting sleeve;

[0007] The upper and lower surfaces of the machine tool control box are equipped with shock absorption mechanisms, and two sets of limiting grooves are opened at both ends of the surface of the lifting sleeve. Each set of limiting grooves is distributed in a fan shape with the threaded rod as the center.

[0008] The machine tool control box has mounting platforms on both the upper and lower surfaces near the lifting sleeve, and a movable rod is rotatably mounted on the surface of the mounting platform.

[0009] One end of the movable rod is provided with a locking head, which cooperates with the inside of the limiting groove to fix the position of the machine tool control box.

[0010] Furthermore, the front surface of the machine body is symmetrically provided with protruding plates, with two protruding plates distributed vertically, and a threaded rod is rotatably installed between the two protruding plates, with a knob installed at the end of the threaded rod.

[0011] Furthermore, the upper and lower ends of the lifting sleeve are provided with sliders, one side of the slider is in contact with the front surface of the machine body, the shock absorption mechanism is sleeved on the surface end of the lifting sleeve, and the shock absorption mechanism is placed between the slider and the machine tool control box.

[0012] Furthermore, a pressure plate is provided at the end of the movable rod away from the chuck, and a return spring is installed at the bottom of the pressure plate. The end of the return spring away from the pressure plate is in contact with the surface of the machine tool control box, and the return spring applies an outward force to the pressure plate.

[0013] Furthermore, a pressing inclined plate is provided at the end of the pressure plate away from the movable rod, and protrusions are provided on both the upper and lower surfaces of the machine tool control box. Fixed track rods are symmetrically provided on both the upper and lower surfaces of the machine tool control box, and the pressing inclined plate is placed between the two fixed track rods.

[0014] Furthermore, a U-shaped control frame is slidably installed on the side of the machine tool control box away from the lifting sleeve. Two protrusions pass through both ends of the U-shaped control frame, and a pressing slide is provided at the end of the U-shaped control frame.

[0015] Furthermore, the extrusion slide plate slides on the surfaces of the two fixed track rods on the same side, and the end of the extrusion slide plate is provided with an arc surface, and the arc surface of the end of the extrusion slide plate is in contact with the inclined surface of the extrusion inclined plate.

[0016] Furthermore, the damping mechanism includes an upper ring and a lower ring, with connecting bolts symmetrically screwed onto the surface of the lower ring, and the lower ring is fixed to the surface of the machine tool control box by the connecting bolts.

[0017] Furthermore, the upper ring abuts against the inner side of the slider, and damping springs are symmetrically arranged between the upper ring and the lower ring, with the two damping springs respectively placed on both sides of the lifting sleeve.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The machine tool control box forms a vibration isolation connection with the slider through the shock absorption mechanism located at both ends of the lifting sleeve. The shock absorption mechanism is equipped with symmetrically distributed damping springs. The upper ring cooperates with the slider to achieve buffer contact, and the lower ring is rigidly fixed to the machine tool control box with bolts. It can effectively absorb the periodic impact generated during the operation of the machine tool, avoid the vibration from being directly transmitted to the control box, improve the overall stability of the control box operation, and solve the problem of loosening and resonance of the control box under long-term operation or high-frequency operation in traditional structures.

[0020] The lifting sleeve is screwed onto the front of the machine body via a threaded rod, and a knob is provided at the end of the threaded rod for height adjustment. Limiting sliders are provided at both the upper and lower ends of the lifting sleeve. The sliders fit against the front surface of the machine body to ensure accurate structural guidance and no rotational deviation during the lifting process. This makes the height adjustment process of the control box controllable and precise. The shock absorption mechanism can still fit the working part at different heights and continuously provide shock absorption function, thereby solving the problem of decreased shock absorption performance caused by lifting in the existing support structure.

[0021] The machine tool control box has limit grooves on its surface for angle positioning. Each set of limit grooves is distributed in a fan shape with the lifting shaft as the center. The chuck structure can be accurately embedded into the limit groove to fix the rotation angle. Together with the movable rod, pressure plate and return spring, it forms a self-locking limit mechanism. The chuck can automatically position itself when no force is applied, ensuring that the angle of the control box does not shift due to environmental vibration or misoperation. This solves the problem of angle slippage caused by vibration after the angle of the control box is adjusted in the traditional structure.

[0022] A U-shaped control frame is set on one side of the control box to form a linkage mechanism with the extrusion slide plate and the extrusion ramp plate. Linear guidance can be achieved through the cooperation of the slide plate and the fixed track rod. The extrusion structure can release the limit with the movable rod, realizing the rapid adjustment of the angle of the control box. The arc surface of the extrusion slide plate and the slope of the ramp plate can stably release the chuck structure, thereby improving the adjustment accuracy and operation convenience, effectively overcoming the problems of complex rotary unlocking structure and difficult adjustment by the operator in the existing device.

[0023] After the angle adjustment is completed, the machine tool control box can rely on the action of the return spring to quickly return the chuck to the limit groove, thereby realizing the self-locking position again. The chuck and the limit groove can have a moderate sliding fit, and can still maintain the angle stability without loosening when small vibrations occur. This improves the dynamic holding ability of the control box after the rotation angle is adjusted, avoids repeated positioning during operation, and improves the operating efficiency and the overall stability of the machine tool operation.

[0032] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0033] refer to Figures 1-6As shown, a vibration-damping and stabilizing support structure for a machine tool functional component includes a machine body 1. Two convex plates 11 are symmetrically arranged on one side of the front surface of the machine body 1, distributed vertically. A threaded rod 12 is rotatably mounted between the two convex plates 11. A knob 13 is installed at the end of the threaded rod 12. A lifting sleeve 2 is screwed onto the surface of the threaded rod 12. Slider blocks 21 are provided at both the upper and lower ends of the lifting sleeve 2. One side of the slider 21 contacts the front surface of the machine body 1. A machine tool control box 4 is rotatably mounted on the surface of the lifting sleeve 2. Vibration damping mechanisms 3 are installed on both the upper and lower surfaces of the machine tool control box 4. The vibration damping mechanisms 3 are fitted onto the surface ends of the lifting sleeve 2 and are positioned between the slider 21 and the machine tool control box 4. The vibration damping mechanisms 3 are used to mitigate vibration and impact caused by machine tool operation or environmental factors. To improve the structural stability of the machine tool control box 4, two sets of limiting grooves 22 are provided at both ends of the surface of the lifting sleeve 2. Each set of limiting grooves 22 is distributed in a fan shape with the threaded rod 12 as the center. The limiting grooves 22 are used to precisely limit the rotation angle in conjunction with the chuck structure to ensure that the machine tool control box 4 can remain stable and not deviate after the angle is adjusted. The upper and lower surfaces of the machine tool control box 4 are provided with mounting platforms 42 on the side near the lifting sleeve 2. A movable rod 5 is rotatably mounted on the surface of the mounting platform 42. A chuck 51 is provided at one end of the movable rod 5, and a pressure plate 52 is provided at the other end of the movable rod 5. The chuck 51 is adapted to the internal size of the limiting groove 22. The chuck 51 rotates and fixes the machine tool control box 4 by limiting the rotation, thereby avoiding problems such as angle loosening during operation or vibration.

[0034] refer to Figure 3 and Figure 6 As shown, a return spring 53 is installed at the bottom of the pressure plate 52. The end of the return spring 53 away from the pressure plate 52 is in contact with the surface of the machine tool control box 4. The return spring 53 applies an outward force to the pressure plate 52. The presence of the return spring 53 ensures that the movable rod 5 can maintain its original position when it is not under force, and causes the chuck 51 to naturally embed into the corresponding limit groove 22 to achieve automatic positioning. In actual use, the elastic force of the return spring 53 can quickly reset the chuck 51 and maintain the angle stability. Even if the machine tool operation causes slight vibration, it will not deviate, thereby improving the structural reliability of the machine tool control box 4 after the angle is adjusted.

[0035] refer to Figure 3 and Figure 6As shown, a pressing plate 52 is provided with a pressing inclined plate 54 at the end opposite to the movable rod 5. Both the upper and lower surfaces of the machine tool control box 4 are provided with protrusions 41, and both the upper and lower surfaces of the machine tool control box 4 are symmetrically provided with fixed track rods 43. The pressing inclined plate 54 is placed between two fixed track rods 43. A linkage structure is formed between the pressing inclined plate 54 and the movable rod 5. When an external force pushes the pressing inclined plate 54 to move, it will force the pressing plate 52 to move in the opposite direction along the reset direction, thereby causing the chuck 51 to pry out and disengage from the limiting groove 22, allowing the machine tool control box 4 to be rotated and adjusted. The two fixed track rods 43 limit and guide the movement direction of the pressing inclined plate 54, ensuring that the pressing inclined plate 54 maintains linear and controlled movement when subjected to external force, without shaking or slipping, effectively improving the reliability and response efficiency of the entire adjustment system.

[0036] refer to Figure 3 As shown, a U-shaped control frame 6 is slidably installed on the side of the machine tool control box 4 away from the lifting sleeve 2. Two protrusions 41 pass through both ends of the U-shaped control frame 6, and a pressing slide plate 61 is provided at the end of the U-shaped control frame 6. The U-shaped control frame 6 is the operation trigger component of the machine tool control box 4. Its position is convenient for the operator to apply external force to achieve angle unlocking operation. The protrusions 41 are used to limit the lateral displacement of the U-shaped control frame 6 during the sliding process, ensuring that it moves linearly in the set direction. The pressing slide plate 61 is the end-acting component of the U-shaped control frame 6. When the operator pushes the U-shaped control frame 6 to move, the pressing slide plate 61 can effectively cooperate with the pressing inclined plate 54 to complete the release action of the movable rod 5, thereby realizing the unlocking control of the angle adjustment of the machine tool control box 4.

[0037] refer to Figure 3 and Figure 5 As shown, the extrusion slide plate 61 slides on the surfaces of two fixed track rods 43 on the same side. The end of the extrusion slide plate 61 is provided with an arc surface, and the arc surface at the end of the extrusion slide plate 61 contacts the inclined surface of the extrusion inclined plate 54. The arc surface structure can form a surface contact relationship with the inclined surface during the application of force, thereby obtaining a more uniform and stable force transmission path when interacting, avoiding structural wear or sliding failure caused by point contact. The sliding mode of the extrusion slide plate 61 on the fixed track rod 43 can precisely control its movement trajectory. Combined with the oblique interaction relationship between the arc surface and the inclined surface, the rotation of the movable rod 5 is more sensitive and smooth, ultimately ensuring that the chuck 51 can accurately and quickly disengage from or insert into the limiting groove 22, thereby ensuring the controllability and reliability of the angle adjustment of the machine tool control box 4.

[0038] refer to Figure 4 and Figure 5As shown, the vibration damping mechanism 3 includes an upper ring 31 and a lower ring 32. The lower ring 32 has connecting bolts 33 symmetrically screwed onto its surface, and the lower ring 32 is fixed to the surface of the machine tool control box 4 by the connecting bolts 33. The vibration damping mechanism 3 achieves the vibration buffering function through the elastic connection between the upper ring 31 and the slider 21. At the same time, the lower ring 32 is stably fixed to the surface of the machine tool control box 4 by the connecting bolts 33, realizing the rigid connection and vibration isolation between the vibration damping component and the control box. This structure allows the vibration damping mechanism 3 to not only always fit the surface end of the lifting sleeve 2 during use, but also to ensure that it continues to perform the vibration damping function under different height or angle adjustment states.

[0039] refer to Figure 5 As shown, the upper ring 31 abuts against the inner side of the slider 21, and damping springs 34 are symmetrically arranged between the upper ring 31 and the lower ring 32. The two damping springs 34 are respectively placed on both sides of the lifting sleeve 2. The damping springs 34 can absorb the periodic impact force from the machine tool operation and dissipate energy through elastic deformation, thereby reducing the instantaneous impact transmission to the machine tool control box 4. The symmetrical arrangement of the damping springs 34 not only improves the overall force balance of the damping mechanism 3, but also ensures that the support effect on both sides is consistent when the control box rotates, and does not cause structural tilting or damping failure due to rotation, thereby further enhancing the safety and stability of the machine tool functional components.

[0040] The working principle of this utility model is as follows: During use, the two shock-absorbing mechanisms 3 on the upper and lower parts of the machine tool control box 4 are used to position the machine tool control box 4 at the center of the two sliders 21. The shock-absorbing mechanisms 3 are fixed to the machine tool control box 4 by connecting bolts 33. Therefore, the rotation of the machine tool control box 4 can drive the shock-absorbing mechanism 3 to rotate as a whole. The shock-absorbing mechanism 3 can always maintain the shock-absorbing work of the machine tool control box 4. When there is no force, due to the presence of the return spring 53, the pressure plate 52 always has a force away from the direction of the machine tool control box 4, which in turn pushes the movable rod 5 to rotate, so that the chuck 51 can cooperate with the corresponding limit groove 22 to achieve fixation. Since the movable rod 5 is installed on the mounting table 42, the movable rod 5 only It can rotate around its axis, so the cooperation between the chuck 51 and the corresponding limiting groove 22 can fix the angle of the machine tool control box 4. When it is necessary to adjust the angle of the machine tool control box 4 for user operation, the U-shaped control frame 6 can be pressed to move the U-shaped control frame 6 towards the lifting sleeve 2. The U-shaped control frame 6 is fixed by two protrusions 41 to maintain its stable movement. The movement of the U-shaped control frame 6 can synchronously drive the upper and lower extrusion slide plates 61 to move, and then the arc surface at the end of the extrusion slide plate 61 extrudes the inclined surface of the extrusion inclined plate 54, causing the movable rod 5 to rotate. At this time, the chuck 51 is no longer engaged with the limiting groove 22. At this time, the machine tool control box 4 can rotate at any angle.

[0041] Conversely, after adjustment, the return spring 53 can be used to return the movable rod 5 and the U-shaped control frame 6 to their original positions. After the chuck 51 is engaged, it can also slide up and down within the limiting groove 22. Therefore, even if vibration occurs, it will not affect the fixation of the angle. At the same time, the height of the machine tool control box 4 can be adjusted according to the user's height. During adjustment, the knob 13 is rotated to control the rotation of the threaded rod 12. Then, the rotation of the threaded rod 12 drives the lifting sleeve 2 to move up and down. Since one side of the slider 21 is in contact with the front surface of the machine body 1, the lifting sleeve 2 can only move axially and cannot rotate. This structure can adjust the height of the machine tool control box 4 and keep the upper and lower shock-absorbing mechanisms 3 always having a shock-absorbing effect on the machine tool control box 4, unaffected by height changes. At the same time, the angles of the two movable rods 5 can be synchronously controlled to improve the stability of the angle of the machine tool control box 4 after rotation, and there will be no mutual influence between them and the shock-absorbing mechanism 3.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
