Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to an auxiliary support device based on two-point linkage. Background Technology

[0002] In the field of machining, after a workpiece is fixed and clamped by a fixture or other device, it is not entirely in a stable state. During the machining process where the cutting tool is in contact with the workpiece, vibration can easily occur due to fluctuations in cutting force. This vibration not only damages the surface finish of the workpiece but may also affect the tool's lifespan and even pose a machining safety hazard. Therefore, it is usually necessary to use a manual auxiliary support structure to provide reverse support and locking for the workpiece. By supplementing the support force, the adverse effects of vibration are offset, thereby ensuring the stability of the workpiece throughout the cutting process and guaranteeing machining quality and efficiency.

[0003] However, the manual auxiliary support structures widely used in the industry currently have significant technical limitations: their operation mode is singular, and a single operation can only lock and fix one auxiliary support point. This characteristic, in scenarios requiring multiple support points to work together, leads to operators having to perform multiple operations repeatedly, which not only increases the complexity and time cost of the operation process, but also makes it difficult to efficiently complete auxiliary support tasks in locations with narrow internal space and where hand dexterity is limited. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary support device based on two-point linkage to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An auxiliary support device based on two-point linkage includes: The base is hollow inside to provide installation space; The first support base and the second support base are installed at an interval on the top of the base; The first inclined pin and the second inclined pin are respectively movably disposed in the central holes of the first support base and the second support base in the vertical direction, and both of them are equipped with support columns for supporting the workpiece at their top ends. A screw, rotatably connected at both ends to the side walls of the base, located at the lower part of the base, with a protruding reference portion in its middle; and A left-hand threaded block and a right-hand threaded block are both threaded onto the screw and located on both sides of the protruding reference portion, and the top of both have a bevel that matches the first bevel pin and the second bevel pin. The first inclined pin and the second inclined pin both achieve elastic displacement within a preset vertical stroke through an elastic component and a limiting component.

[0006] In one possible implementation, the left-hand threaded block has the opposite thread direction to the right-hand threaded block; When the screw is rotating, the left-hand threaded block and the right-hand threaded block move toward or away from each other.

[0007] In one possible implementation, the bottom slopes of the first and second inclined pins are inclined in opposite directions, with the bottom slopes of both inclined in a downward direction from their opposite sides.

[0008] In one possible implementation, the limiting component includes: A limiting groove, which is vertically formed on the upper sidewall of the first inclined pin and the second inclined pin; and A limiting post is horizontally disposed in the sidewalls of the first support base and the second support base; One end of the limiting post is located inside the limiting groove.

[0009] In one possible implementation, the resilient component includes: A convex ring, disposed at the middle of the first beveled pin and the second beveled pin; and The return spring has its top end connected to the convex ring and its bottom end connected to the bottom of the first support and the second support.

[0010] In one possible implementation, the support column is fixed to the top of the first and second beveled pins by a dust cap.

[0011] In one possible implementation, one end of the screw extends to the outside of the base and is fitted with a rotating handle.

[0012] In one possible implementation, the bottom bevels of the first beveled pin and the second beveled pin, as well as the top bevels of the left-hand threaded block and the right-hand threaded block, all have micro-tooth-like surface structures.

[0013] The beneficial effects of the technical solution provided by this utility model include at least the following: This technical solution can simultaneously lock two auxiliary support points in a single operation, significantly reducing operation steps and repetitive actions compared to traditional structures that lock only one support point at a time. This lowers operator workload, shortens support setup time, and effectively improves overall processing efficiency. Furthermore, it overcomes the limitations of traditional structures, enabling support fixation in confined spaces and difficult-to-handle environments without requiring multiple posture adjustments, significantly enhancing ease of operation and adaptability. In addition, its inherent locking characteristics generate continuous and stable support force, resisting external forces such as cutting vibration and impact, preventing support point loosening and displacement. It requires no additional power source, simplifying the structure while reducing the risk of failure and ensuring stable and reliable support performance over long-term use.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Figure 1 This illustration shows an axonometric view of an auxiliary support device based on two-point linkage, provided in an exemplary embodiment of the present invention. Figure 2 This illustration shows a front cross-sectional view of an auxiliary support device based on two-point linkage, provided by an exemplary embodiment of the present invention. The auxiliary support device includes: a base 1, which is hollow inside to provide installation space; a first support seat 2 and a second support seat 3, which are spaced apart and mounted on the top of the base 1; a first inclined pin 4 and a second inclined pin 5, which are movably disposed vertically within the central holes of the first support seat 2 and the second support seat 3, respectively, and both have support columns 6 for supporting workpieces mounted at their top ends; a screw 7, whose two ends are rotatably connected to the two side walls of the base 1, located at the lower part of the base 1, and having a raised reference portion 71 in its middle; and a left-hand threaded block 8 and a right-hand threaded block 9, both threadedly connected to the screw 7 and located on both sides of the raised reference portion 71, with inclined surfaces at their tops adapted to the first inclined pin 4 and the second inclined pin 5; wherein the first inclined pin 4 and the second inclined pin 5 each achieve elastic displacement within a preset vertical stroke through an elastic component 10 and a limiting component 11.

[0022] In this embodiment, the first support base 2 and the second support base 3 are spaced apart and installed on the top of the base 1 to position and support the first inclined pin 4 and the second inclined pin 5, ensuring the stability of the first inclined pin 4 and the second inclined pin 5 when they move in the vertical direction. The first inclined pin 4 and the second inclined pin 5 can move vertically along the central holes of the first support base 2 and the second support base 3. The support column 6 at the top of the first inclined pin 4 and the second inclined pin 5 directly contacts the workpiece to support it. The screw 7 separates the left-hand threaded block 8 and the right-hand threaded block 9 through the protruding reference part 71 in its middle. When the screw 7 rotates, it can drive the left-hand threaded block 8 and the right-hand threaded block 9 to move towards or away from each other. The inclined surface at the top of the left-hand threaded block 8 and the right-hand threaded block 9 is adapted to the inclined surface of the first inclined pin 4 and the second inclined pin 5, thereby locking the first inclined pin 4 and the second inclined pin 5. The elastic component 10 and the limiting component 11 cooperate with each other to enable the first inclined pin 4 and the second inclined pin 5 to achieve elastic displacement within a preset stroke in the vertical direction.

[0023] For details, please refer to Figure 2 The left-hand threaded block 8 and the right-hand threaded block 9 have opposite thread directions; when the screw 7 is rotating, the left-hand threaded block 8 and the right-hand threaded block 9 move towards or away from each other. In addition, the left-hand threaded block 8 and the right-hand threaded block 9 are clearance-fitted with the inner bottom of the base 1, so that the threaded blocks will not be overturned to the side without affecting their movement.

[0024] For more details, see [link to relevant documentation]. Figure 2 The bottom inclined surfaces of the first inclined pin 4 and the second inclined pin 5 are inclined in opposite directions, and the bottom inclined surfaces of the two are inclined downward from the opposite side to the opposite side.

[0025] It is worth mentioning that, see Figure 2 The bottom bevels of the first bevel pin 4 and the second bevel pin 5, as well as the top bevels of the left-hand threaded block 8 and the right-hand threaded block 9, all adopt a micro-tooth-like structure surface.

[0026] In this embodiment, the bottom inclined surfaces of the first inclined pin 4 and the second inclined pin 5 are inclined in opposite directions to adapt to the inclined surfaces of the left-hand threaded block 8 and the right-hand threaded block 9; each inclined surface is provided with a micro-tooth-like structure surface to enhance locking stability and ensure efficient and reliable two-point linkage support.

[0027] Specifically, see Figure 2 The limiting component 11 includes: a limiting groove 111, which is vertically opened on the upper side wall of the first inclined pin 4 and the second inclined pin 5; and a limiting post 112, which is horizontally disposed in the side wall of the first support seat 2 and the second support seat 3; wherein one end of the limiting post 112 is located in the limiting groove 111.

[0028] In this embodiment, the limiting groove 111 and the limiting post 112 cooperate to limit the vertical displacement range of the first inclined pin 4 and the second inclined pin 5, preventing them from detaching from the first support seat 2 and the second support seat 3, and ensuring the stability of elastic displacement.

[0029] More specifically, see Figure 2 The elastic component 10 includes: a convex ring 101 disposed in the middle of the first inclined pin 4 and the second inclined pin 5; and a return spring 102, the top end of which is connected to the convex ring 101, and the bottom end of which is connected to the bottom of the first support seat 2 and the second support seat 3.

[0030] In this embodiment, the top end of the return spring 102 is connected to the protruding ring 101, and the bottom end is connected to the bottom of the first support seat 2 and the second support seat 3. The two work together to provide elastic support for the first inclined pin 4 and the second inclined pin 5, so that the support column 6 always fits the workpiece. It can also assist the first inclined pin 4 and the second inclined pin 5 in resetting, ensuring the adaptability and ease of operation of the two-point linkage support.

[0031] Further, see Figure 1 and Figure 2 The support column 6 is fixed to the top of the first inclined pin 4 and the second inclined pin 5 by a dust cap 12. One end of the screw 7 extends to the outside of the base 1 and is equipped with a rotating handle 13.

[0032] In this embodiment, the dust cap 12 can prevent dust and impurities from entering the gap between the support and the inclined pin, thus avoiding affecting the accuracy of the component's movement.

[0033] Next, the working principle of an auxiliary support device based on two-point linkage involved in the embodiments of this utility model will be explained.

[0034] In the initial state, both the left-hand threaded block 8 and the right-hand threaded block 9 are tightly fitted with the protruding reference part 71 of the screw 7, and neither of them is in contact with the first inclined pin 4 or the second inclined pin 5. When the workpiece is placed on the two support columns 6, the return spring 102 in the elastic component 10 provides elastic support, so that the two support columns 6 always keep in contact with the workpiece support point. The operator then drives the screw 7 to rotate by turning the rotating handle 13 on the outside of the screw 7, causing the left-hand threaded block 8 and the right-hand threaded block 9 to move in opposite directions along the screw 7. When either of them contacts the first inclined pin 4 or the second inclined pin 5, the operator continues to turn the rotating handle 13. The screw 7 will perform position compensation along the axial direction until the left-hand threaded block 8 and the right-hand threaded block 9 are fully in contact with the first inclined pin 4 and the second inclined pin 5 and locked. At this time, the entire auxiliary support device completes the locking operation. When released, simply rotate the handle 13 in the opposite direction, and the left-hand threaded block 8 and the right-hand threaded block 9 will move towards each other along the screw 7, gradually disengaging completely from the first inclined pin 4 and the second inclined pin 5, until they re-engage with the protruding reference part 71 of the screw 7, and the auxiliary support device returns to its initial state.

[0035] In summary, this technical solution can simultaneously lock two auxiliary support points in a single operation. Compared to the traditional structure that locks only one support point at a time, it significantly reduces operation steps and repetitive actions, lowers the labor intensity of operators, shortens support setup time, and effectively improves overall processing efficiency. Furthermore, it overcomes the limitations of traditional structures, enabling support fixation in inconvenient working conditions such as narrow spaces and difficult hand positions without multiple posture adjustments, significantly improving operational convenience and adaptability. In addition, relying on its own locking characteristics to form a continuous and stable support force, it can resist external forces such as cutting vibration and impact, preventing support point loosening and displacement. It requires no additional power source, simplifies the structure, reduces the risk of failure, and ensures stable and reliable support performance during long-term use.

[0036] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
