Description

Technical Field

[0001] This utility model relates to the field of parts processing, and in particular to a movable floating support structure for machining fixtures. Background Technology

[0002] During machining, parts need to be clamped using fixtures. Floating support cylinders are a common auxiliary support component, typically fixedly mounted on the machine tool. They generate support force through pneumatic or hydraulic cylinders, providing bottom or lateral support for the part. For large or irregularly shaped parts, using fixed floating support cylinders often leads to interference with the part, clamping device, or cutting tool, restricting the support position. Furthermore, insufficient or improperly positioned support and clamping points can cause machining instability. Utility Model Content

[0003] Therefore, it is necessary to provide a movable floating support structure for machining fixtures to solve the problem of instability when fixed floating support cylinders support irregularly shaped parts.

[0004] To achieve the above objectives, the inventors provide a movable floating support structure for machining fixtures, comprising: a machine tool and a floating support cylinder, wherein the floating support cylinder is disposed on the machine tool. The movable floating support structure further comprises: a linear movement device, wherein the linear movement device includes a linear telescopic mechanism and a linear sliding mechanism. The linear telescopic mechanism includes a body and a telescopic component, wherein the body is disposed on the machine tool, and the telescopic component can move linearly relative to the body. The floating support cylinder is connected to the telescopic component and disposed on the machine tool through the linear sliding mechanism. Under the drive of the linear telescopic mechanism, the floating support cylinder moves along a linear direction through the linear sliding mechanism.

[0005] Furthermore, it also includes a limiting mechanism, which is used to limit the floating support cylinder.

[0006] Furthermore, the limiting mechanism includes a first limiting block and a second limiting block. The first limiting block is disposed on the machine tool and located on one side of the linear sliding mechanism. The second limiting block is disposed on the floating support cylinder and moves with the movement of the floating support cylinder. The first limiting block is located on the movement path of the second limiting block. When the first limiting block blocks the second limiting block, the limiting mechanism limits the floating support cylinder.

[0007] Furthermore: the first limiting block has a first inclined surface, and the second limiting block has a second inclined surface. The first inclined surface matches the second inclined surface so that the second limiting block stops and fits on the first inclined surface of the first limiting block via the second inclined surface.

[0008] Furthermore, the limiting mechanism is located at one end of the linear sliding mechanism near the linear telescopic mechanism.

[0009] Furthermore: the linear telescopic mechanism is a cylinder, the body is the cylinder body, the telescopic component includes the piston rod of the cylinder and a connector sleeved on the piston rod, and the telescopic component is connected to the floating support cylinder through the connector.

[0010] Furthermore: the joint is sleeved with the floating support cylinder.

[0011] Furthermore, the linear telescopic mechanism is a hydraulic cylinder.

[0012] Furthermore, the linear sliding mechanism is a linear guide rail.

[0013] Furthermore, it also includes a fixing block, through which the body is mounted on the machine tool.

[0014] Unlike existing technologies, the above technical solution has the following beneficial effects:

[0015] The movable floating support structure optimizes the application conditions of existing fixed floating support cylinders, making their application more diverse in location and occasion. It enables the use of floating support cylinders even in more complex or confined spaces. With this structure, the position of the floating support cylinder can be moved during processing, avoiding interference. Similarly, during product clamping, the floating support cylinder can be manually moved to a more convenient position for the operator, reducing their workload.

[0033] Please see Figures 1 to 4This embodiment provides a movable floating support structure for machining fixtures, including: a machine tool 5 and a floating support cylinder 2. The floating support cylinder 2 is mounted on the machine tool 5 and is used to provide auxiliary support for the workpiece during machining to ensure the stability of machining.

[0034] The movable floating support structure also includes a linear movement device 3, which comprises a linear telescopic mechanism 31 and a linear sliding mechanism 32. The linear telescopic mechanism 31 includes a body 311 and a telescopic member 312. The body 311 is mounted on the machine tool 5, and the telescopic member 312 can move linearly relative to the body 311. The floating support cylinder 2 is connected to the telescopic member 312 and is mounted on the machine tool 5 via the linear sliding mechanism 32. Driven by the linear telescopic mechanism 31, the floating support cylinder 2 moves in a straight line via the linear sliding mechanism 32. The linear telescopic mechanism 31 achieves linear telescopic movement through the telescopic member 312. When the telescopic member 312 moves, it can drive the floating support cylinder 2 to translate. The linear sliding mechanism 32 guides the movement of the floating support cylinder 2, allowing it to slide smoothly in a predetermined direction, thereby avoiding deviation or tilting.

[0035] When the telescopic component 312 moves linearly in one direction, the floating support cylinder 2 moves forward in a linear direction under the guidance of the linear sliding mechanism 32; when the telescopic component 312 moves linearly in the opposite direction, the floating support cylinder 2 retracts accordingly. By controlling the extension and retraction stroke of the telescopic component 312, the position of the floating support cylinder 2 on the machine tool 5 can be flexibly adjusted to adapt to workpieces of different shapes and sizes.

[0036] The movable floating support structure can optimize the application conditions of the existing fixed floating support cylinder 2, making its application location and occasions more diversified. It can also be used in more complex or narrower spaces. With this structure, the position of the floating support cylinder 2 can be moved during processing to avoid interference. Similarly, during product clamping, the floating support cylinder 2 can be manually moved to a more convenient position for the operator, reducing the operator's workload.

[0037] Please see Figure 1 In some embodiments, the movable floating support structure further includes a limiting mechanism 4, which is used to limit the movement of the floating support cylinder 2. The position of the limiting mechanism 4 corresponds to the movement path of the floating support cylinder 2, effectively preventing the floating support cylinder 2 from exceeding the predetermined working range under the drive of the linear telescopic mechanism 31. This protects the linear sliding mechanism 32 and the telescopic member 312 from mechanical damage caused by over-travel impact, and also ensures that the floating support cylinder 2 remains within a safe range during the adjustment of the support position.

[0038] Please see Figure 1 and Figure 2In some embodiments, the limiting mechanism 4 includes a first limiting block 41 and a second limiting block 42. The first limiting block 41 is mounted on the machine tool 5 and located on one side of the linear sliding mechanism 32. The second limiting block 42 is mounted on the floating support cylinder 2 and moves with the floating support cylinder 2. The first limiting block 41 is located on the moving path of the second limiting block 42. When the first limiting block 41 blocks the second limiting block 42, the limiting mechanism 4 limits the floating support cylinder 2. When the floating support cylinder 2 moves to a predetermined limiting position (extreme position), the second limiting block 42 contacts the first limiting block 41. After they contact each other, a mechanical limit is formed, preventing the floating support cylinder 2 from continuing to move, thereby realizing the control of the movement range of the floating support cylinder 2. With this structural arrangement, the stroke range of the floating support cylinder 2 is determined by the relative position between the two limiting blocks, and the position of the limiting blocks can be adjusted according to actual needs to change the movable range of the floating support cylinder 2.

[0039] Please see Figure 2 In some embodiments, the first limiting block 41 has a first inclined surface 411, and the second limiting block 42 has a second inclined surface 421. The first inclined surface 411 and the second inclined surface 421 are matched so that the second limiting block 42 stops and abuts against the first inclined surface 411 of the first limiting block 41 via the second inclined surface 421. The first inclined surface 411 and the second inclined surface 421 are arranged opposite each other with the same inclination angle. During limiting, the two inclined surfaces contact and abut against each other, forming a stable contact limiting state, which can effectively reduce the limiting impact force, reduce mechanical wear, and extend the service life of the mechanism.

[0040] Please see Figure 1 In some embodiments, the limiting mechanism 4 is located at the end of the linear sliding mechanism 32 near the linear telescopic mechanism 31 to prevent interference or collision between the floating support cylinder 2 and the linear telescopic mechanism 31. In other embodiments, the limiting mechanism 4 can limit the floating support cylinder 2 at the end away from the linear telescopic mechanism 31.

[0041] Please see Figure 4 In a preferred embodiment, two first limiting blocks 41 and two second limiting blocks 42 are provided, respectively located on both sides of the linear sliding mechanism 32, and are symmetrically distributed. Through the symmetrical cooperation of the limiting blocks on both sides, the floating support cylinder 2 can be limited from both sides at the end of its stroke, ensuring balanced limiting force and avoiding limiting failure caused by abnormal cooperation between a single first limiting block 41 and second limiting block 42.

[0042] In the above embodiments, the limiting mechanism 4 adopts a structure in which the first limiting block 41 and the second limiting block 42 cooperate to limit the floating support cylinder 2. Alternatively, in another embodiment, the limiting mechanism has only one limiting block, which is fixed to the machine tool and located at the end of the floating support cylinder's movement path. The floating support cylinder directly contacts this limiting block, thereby achieving the limiting effect. This structure is simple and easy to install, but because the contact between the floating support cylinder and the limiting block is rigid, long-term operation can easily cause surface wear on the floating support cylinder, which is detrimental to extending its service life. In yet another embodiment, the limiting mechanism can install a proximity switch at the end of the floating support cylinder's movement path. When the floating support cylinder moves to a predetermined position, it sends an electrical signal to control a limiting arm to stop the floating support cylinder from continuing to move.

[0043] Please see Figure 1 and Figure 3 In some embodiments, the linear telescopic mechanism 31 is a cylinder, the body 311 is the cylinder body, and the telescopic component 312 is the piston rod of the cylinder. The cylinder uses compressed air as a power source, and the reciprocating linear motion of the piston rod is achieved by controlling the air intake and exhaust directions. When compressed air is introduced into the cylinder, the piston rod pushes outward, driving the floating support cylinder 2 to move along the linear sliding mechanism 32; when the cylinder exhausts or reverses direction, the piston rod retracts, and the floating support cylinder 2 moves in the opposite direction.

[0044] Please see Figure 1 and Figure 3 In some embodiments, the telescopic member 312 includes a piston rod of a cylinder and a connector 313 sleeved on the piston rod. The telescopic member 312 is connected to the floating support cylinder 2 through the connector 313. Preferably, the connector 313 is sleeved with the floating support cylinder 2, and the floating support cylinder 2 is provided with a slot 21. The connector 313 can be sleeved in the slot 21 in a direction perpendicular to the movement of the telescopic member 312. Alternatively, the connector 313 can be fastened to the floating support cylinder 2 by bolts.

[0045] In some embodiments, the linear telescopic mechanism 31 is a hydraulic cylinder. The hydraulic cylinder also includes a cylinder body and a piston rod, with the piston rod acting as a telescopic member 312 connected to the floating support cylinder 2. The hydraulic cylinder uses hydraulic oil as a medium, and by controlling the hydraulic pressure in the oil circuit, the extension and retraction of the piston rod are achieved.

[0046] Preferably, both the linear telescopic mechanism 31 and the floating support cylinder 2 are in the form of cylinders.

[0047] Please see Figure 1 In some embodiments, the linear sliding mechanism 32 is a linear guide rail. The linear guide rail includes a guide rail body and a slider. The guide rail body plays a precise guiding role, and the slider can slide along the guide rail body and support the floating support cylinder 2 above it to reduce frictional resistance and ensure smooth and stable movement.

[0048] In some other embodiments, the linear sliding mechanism 32 adopts a sliding rod and sliding sleeve cooperation form. Two parallel sliding rods are fixed on the machine tool, and a sliding sleeve is provided on the floating support cylinder. The sliding sleeve is sleeved on the outside of the sliding rod and can slide along the direction of the sliding rod.

[0049] Please see Figure 1 and Figure 4 In some embodiments, the movable floating support structure further includes a fixing block 1, and the main body 311 is mounted on the machine tool 5 via the fixing block 1. The fixing block 1 can be installed by screw connection, pressure plate fixation or embedding method, so that the linear telescopic mechanism 31 maintains a stable position during operation and prevents displacement or vibration.

[0050] Please see Figure 4 The machine tool 5 is equipped with several positioning fixtures 6 to clamp and fix the parts.

[0051] The working principle of a movable floating support structure is described here:

[0052] The linear telescopic mechanism uses a cylinder. When the cylinder is vented, it extends, and the linear guide rail drives the floating support cylinder to move, thereby changing the position of the floating support cylinder. When resetting, the cylinder retracts after being vented, and the linear guide rail drives the floating support cylinder to move to complete the reset.

[0053] This is suitable for products with large and irregular shapes. In practical applications of machining fixtures, unstable machining is often encountered. This is often due to insufficient support and clamping points for fixing the product. However, if a fixed floating support is used in the traditional way, it will interfere with the machining or the installation of the product, affecting the machining cycle and manual operation.

[0054] The advantages of this structure are its simplicity and low manufacturing cost, which allows for a wide range of applications. It effectively optimizes the space occupied by the fixture while ensuring processing quality, thus ensuring effective control over product quality. Furthermore, it can be integrated with automated applications, allowing the position of the floating support to be adjusted rationally during processing according to changes in the processing content. This enables a single floating support to assist processing at multiple locations, maximizing functionality.

[0055] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
