Description

Technical Field

[0001] This invention relates to the field of tooling and fixture technology, and in particular to a fixing fixture for a rectangular ring product. Background Technology

[0002] In the CNC machining of rectangular ring products (such as sealing rings, gaskets, rectangular frame parts, etc.), the preceding process is usually stamping. Due to factors such as material springback, die wear, and batch differences of raw materials in the stamping process, there are unavoidable batch fluctuations in the dimensions of the incoming rectangular rings (such as side length, flatness, parallelism, diagonal length, etc.).

[0003] In existing technologies, clamping structures are typically used to hold and fix rectangular ring products to ensure their stability. However, existing fixtures can only clamp and fix rectangular ring products from the outside. If the rectangular ring product is large, a larger fixture is required, increasing spare parts costs and reducing efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a fixing fixture for rectangular ring products, which can be selected to fix the product on the inside or outside of the rectangular ring product according to its size, thereby adapting to rectangular ring products of different sizes, reducing spare parts requirements, reducing costs, and improving efficiency.

[0005] To achieve this objective, the embodiments of the present invention adopt the following technical solutions: A fixture for fixing a rectangular ring product includes: The base is used to support the rectangular ring product. The fixing mechanism includes two sets of fixing components, which are slidably disposed on the base along a first direction. Each fixing component includes a guide housing and a pusher, which is slidably disposed on the guide housing. The fixing components can be switched to have an inner fixing state and an outer fixing state. When the fixing component is in the inner fixing state, it is located inside the rectangular ring product and the pusher abuts against the inner side of the rectangular ring product. When the fixing component is in the outer fixing state, it is located outside the rectangular ring product and the pusher abuts against the outer side of the rectangular ring product, so that the two sets of fixing components fix the rectangular ring product in the first direction.

[0006] Preferably, the fixing component further includes a first locking member, which passes through the guide housing and abuts against the pusher to lock the position of the pusher.

[0007] Preferably, the fixing component further includes a second locking member, which passes through the guide housing and abuts against the base to lock the position of the guide housing.

[0008] Preferably, the fixing component further includes an elastic buffer, which is disposed at the end of the pusher to elastically abut against the rectangular ring product.

[0009] Preferably, the fixing component further includes an elastic element disposed within the guide housing, the elastic element elastically driving the pusher to abut against the rectangular ring product.

[0010] Preferably, the guide housing includes a sliding seat and a rotating housing. The rotating housing is rotatably disposed on the sliding seat, and the pusher is slidably disposed on the rotating housing. When the pusher extends inward from the rotating housing, the fixing component is in an externally fixed state, and when the pusher extends outward from the rotating housing, the fixing component is in an internally fixed state.

[0011] Preferably, the sliding seat includes a locking part and a rotating platform. The locking part is provided with a second locking member, which is configured to lock the position of the sliding seat. The top surface of the rotating platform is higher than the second locking member, and the rotating shell is rotatably disposed on the rotating platform.

[0012] Preferably, the guide housing is slidably disposed on the base, and the pusher passes through the guide housing with both ends of the pusher extending out of the guide housing.

[0013] Preferably, the side wall of the pusher is provided with a driving part, and elastic members are provided on both sides of the driving part. The elastic members on both sides of the driving part elastically abut against the driving part to keep the pusher in a balanced position.

[0014] Preferably, a limiting groove is formed inside the guide housing, and along the sliding direction of the pusher, the limiting groove has two limiting surfaces spaced apart, and the drive part is located inside the limiting groove and between the two limiting surfaces.

[0015] The beneficial effects of this invention are: This invention provides a fixing fixture for a rectangular ring product. In this fixture, a base supports the rectangular ring product, and two sets of fixing components are slidably disposed on the base. The distance between the two sets of fixing components can be adjusted according to the size of the rectangular ring product, and a sliding pusher is slidable according to the position of the rectangular ring product, allowing the pusher to abut against the rectangular ring product to ensure its stability. Since the fixing components can be switched to have an inner fixing state and an outer fixing state, when fixing a large-sized rectangular ring product, the fixing components can be switched to the inner fixing state, reducing the distance between the two sets of fixing components, and the rectangular ring product is fitted over the two sets of fixing components. In this case, the pusher abuts against the inner side of the rectangular ring product. When fixing a small-sized rectangular ring product, the fixing components can be switched to the outer fixing state, increasing the distance between the two sets of fixing components, and the rectangular ring product is placed inside the two sets of fixing components. In this case, the pusher abuts against the outer side of the rectangular ring product.

[0016] This fixture can be selected to fix the rectangular ring product on the inside or outside of the product, depending on the size of the product. This allows it to be adapted to rectangular ring products of different sizes, reducing spare parts requirements, lowering costs, and improving efficiency. Attached Figure Description

[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," "combined," "coupled," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a direct connection or an indirect connection via an intermediate medium; or the internal communication of two components or the interaction between two components. As examples, a direct connection refers to two parts or components being connected together without the need for an intermediate medium, while an indirect connection refers to two parts or components each being connected to at least one intermediate medium, with the connection achieved through the intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Furthermore, "connected" and "coupled" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0021] In the description of this invention, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationships shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, in the context, it should be understood that when an element is mentioned as being "upper" or "lower" of another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "above," "on top of," "upper side of," and "above" of the first feature and the second feature include the first feature being directly above, to the upper left, to the upper right, to the upper front, and to the upper rear of the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. The terms "below," "under," "below," and "below" for "first feature" and "second feature" include situations where the first feature is directly below, to the lower left, to the lower right, in front of, or behind the second feature, or simply indicate that the first feature is at a lower horizontal level than the second feature. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1 In the CNC machining of rectangular ring products (such as sealing rings, gaskets, rectangular frame parts, etc.), the preceding process is usually stamping. Due to factors such as material springback, die wear, and batch differences of raw materials in the stamping process, there are unavoidable batch fluctuations in the dimensions of the incoming rectangular rings (such as side length, flatness, parallelism, diagonal length, etc.).

[0024] To ensure the stability of rectangular ring products, clamping structures are typically used to hold and secure them. However, existing fixtures can only clamp and secure the rectangular ring products from the outside. If the rectangular ring products are large, larger fixtures are required, increasing spare parts costs and reducing efficiency.

[0025] To address the above problems, this invention provides a fixing fixture (hereinafter referred to as the fixing fixture) for a rectangular ring product 100. For example... Figures 1-4As shown, the fixing fixture includes a base 1 and a fixing mechanism. The base 1 supports the rectangular ring product 100. The fixing mechanism includes two sets of fixing components 2, which are slidably disposed on the base 1 along a first direction (X direction in the figure). Each fixing component 2 includes a guide housing 21 and a pusher 22, which is slidably disposed on the guide housing 21. The fixing components 2 can be switched to have an internal fixing state and an external fixing state. When the fixing components 2 are in the internal fixing state (e.g., ...), the external fixing state is as follows: Figure 1 When (as shown), the fixing component 2 is located inside the rectangular ring product 100 and the pushing member 22 abuts against the inside of the rectangular ring product 100, the fixing component 2 is in an externally fixed state (as shown). Figure 2 When (as shown), the fixing component 2 is located outside the rectangular ring product 100 and the pusher 22 abuts against the outside of the rectangular ring product 100, so that the two sets of fixing components 2 fix the rectangular ring product 100 in the first direction.

[0026] In this fixture, the base 1 supports the rectangular ring product 100. Two sets of fixing components 2 are slidably disposed on the base 1. The distance between the two sets of fixing components 2 can be adjusted according to the size of the rectangular ring product 100. The pusher 22 slides according to the position of the rectangular ring product 100, so that the pusher 22 can abut against the rectangular ring product 100 to ensure the stability of the rectangular ring product 100. Since the fixing components 2 can be switched to have an inner fixing state and an outer fixing state, when fixing a large-sized rectangular ring product 100, the fixing components 2 can be switched to the inner fixing state, reducing the distance between the two sets of fixing components 2, and the rectangular ring product 100 is placed outside the two sets of fixing components 2. At this time, the pusher 22 abuts against the inner side of the rectangular ring product 100. When fixing a small-sized rectangular ring product 100, the fixing components 2 can be switched to the outer fixing state, increasing the distance between the two sets of fixing components 2, and the rectangular ring product 100 is placed inside the two sets of fixing components 2. At this time, the pusher 22 abuts against the outer side of the rectangular ring product 100.

[0027] This fixing fixture can be selected to fix the rectangular ring product 100 on the inside or outside of the rectangular ring product 100 according to its size, thus adapting to rectangular ring products 100 of different sizes, reducing spare parts requirements, reducing costs, and improving efficiency.

[0028] like Figures 1-4 As shown, the guide housing 21 is slidably disposed on the base 1, and the pusher 22 passes through the guide housing 21 with both ends of the pusher 22 extending out of the guide housing 21. The pusher 22 can move in both directions along the first direction to abut against the rectangular ring product 100 inward or outward.

[0029] In other words, when the size of the rectangular ring product 100 is small, the rectangular ring product 100 can be placed between the two sets of fixing components 2. At this time, the fixing components 2 are in an external fixing state. By adjusting the position of the two fixing components 2, the pushing parts 22 of the two sets of fixing components 2 can abut against the rectangular ring product 100 on the outside. When the size of the rectangular ring product 100 is large, the rectangular ring product 100 can be sleeved outside the two sets of fixing components 2. At this time, the fixing components 2 are in an internal fixing state. By adjusting the position of the two fixing components 2, the pushing parts 22 of the two sets of fixing components 2 can abut against the rectangular ring product 100 on the inside.

[0030] like Figure 3 and Figure 4 As shown, the fixing component 2 also includes an elastic buffer 23, which is disposed at the end of the pusher 22 to elastically abut against the rectangular ring product 100. That is, elastic buffers 23 are provided at both ends of the pusher 22 along the first direction, so that the pusher 22 makes flexible contact with the rectangular ring product 100, thereby protecting the rectangular ring product 100 and avoiding affecting its appearance.

[0031] In this embodiment, the fixing component 2 further includes an elastic element 26, which is disposed within the guide housing 21. The elastic element 26 elastically drives the pusher 22 to abut against the rectangular ring product 100. On the one hand, the elastic element 26 can push the pusher 22 against the rectangular ring product 100 and maintain a certain preload, thereby ensuring the stability of the rectangular ring product 100. On the other hand, the elastic element 26 can make the preload of the pusher 22 on the rectangular ring product 100 continuously change, avoiding the instantaneous increase of preload caused by the displacement of the fixing component 2 leading to rigid contact between the pusher 22 and the rectangular ring product 100, thus protecting the rectangular ring product 100.

[0032] It is worth noting that if the size of the rectangular ring product 100 is small, the operator moves the pusher 22 outward, then places the rectangular ring product 100 between the two sets of fixing components 2 and releases the pusher 22. The pusher 22 can then move inward under the drive of the elastic element 26 and abut against the outer side of the rectangular ring product 100. If the size of the rectangular ring product 100 is large, the operator moves the pusher 22 inward, then places the rectangular ring product 100 outside the two sets of fixing components 2 and releases the pusher 22. The pusher 22 can then move outward under the drive of the elastic element 26 and abut against the outer side of the rectangular ring product 100.

[0033] It is worth noting that, in this embodiment, the inward movement of the pusher 22 refers to the pusher 22 of the fixing component 2 moving towards the fixing component 2 of the same fixing mechanism, that is, the pushers 22 of the two sets of fixing components 2 move closer to each other so that the pusher 22 abuts against the outer side of the rectangular ring product 100 located between the two sets of fixing components 2; the outward movement of the pusher 22 refers to the pusher 22 of the fixing component 2 moving away from the fixing component 2 of the same fixing mechanism, that is, the pushers 22 of the two sets of fixing components 2 move away from each other so that the pusher 22 abuts against the inner side of the rectangular ring product 100 located outside the two sets of fixing components 2.

[0034] like Figure 3 and Figure 4 As shown, the pusher 22 has a protruding drive section 221 on its side wall. Elastic members 26 are provided on both sides of the drive section 221. The elastic members 26 on both sides of the drive section 221 elastically abut against the drive section 221 to keep the pusher 22 in a balanced position. When the pusher 22 is in the balanced position, it can move inward or outward under the operator's drive. When the fixing assembly 2 is in the internal fixed state, the operator pushes the pusher 22 inward, compressing the elastic member 26 on the inner side of the drive section 221 and releasing the elastic member 26 on the outer side. After the rectangular ring product 100 is fitted over the two sets of fixing assemblies 2, the operator releases the pusher 22, and the pusher 22 moves outward under the drive of the elastic member 26 on the inner side of the drive section 221. The pusher 22 moves outward, thereby abutting the inner side of the rectangular ring product 100. Similarly, when the fixing component 2 is in the external fixing state, the operator pushes the pusher 22 outward. The elastic element 26 on the outer side of the drive part 221 of the pusher 22 is compressed, and the elastic element 26 on the inner side is released. When the rectangular ring product 100 is placed between the two sets of fixing components 2, the operator releases the pusher 22. The pusher 22 will move inward under the drive of the elastic element 26 on the outer side of the drive part 221, thereby abutting the outer side of the rectangular ring product 100.

[0035] In this embodiment, a limiting groove 213 is formed inside the guide housing 21. Along the sliding direction of the pusher 22, the limiting groove 213 has two spaced-apart limiting surfaces 214. The drive unit 221 is partially located inside the limiting groove 213 and between the two limiting surfaces 214. When the pusher 22 is in the equilibrium position, the drive unit 221 is located in the middle position of the limiting groove 213. As the pusher 22 moves inward or outward, the drive unit 221 gradually approaches the limiting surface 214 located on the inner side or the limiting surface 214 located on the outer side of the limiting groove 213. When the drive unit 221 abuts against the limiting surface 214 on the corresponding side, the pusher 22 is limited and stops moving.

[0036] To ensure the pusher 22 is subjected to balanced forces, each sidewall of the pusher 22 along the second direction is provided with a drive portion 221, and each drive portion 221 along the first direction is provided with an elastic member 26. To maintain stability between the elastic member 26 and the drive portion 221, the drive portion 221 is provided with a first limiting post, and one end of the elastic member 26 is sleeved on the first limiting post; similarly, to maintain stability between the elastic member 26 and the guide housing 21, the guide housing 21 is provided with a second limiting post, and the other end of the elastic member 26 is sleeved on the second limiting post.

[0037] In this embodiment, the fixing component 2 further includes a first locking member 24, which passes through the guide housing 21 and abuts against the pusher 22 to lock the position of the pusher 22. When the pusher 22 abuts against the rectangular ring product 100, the first locking member 24 can be used to lock the pusher 22, so as to prevent the rectangular ring product 100 from moving due to overcoming the elastic force of the elastic member 26 during CNC machining, thereby improving stability.

[0038] Specifically, the first locking element 24 can be a locking screw, which passes through the guide housing 21 and is threadedly connected to the guide housing 21. The operator can lock the position of the pusher 22 by rotating the locking screw so that the end of the locking screw abuts against the pusher 22.

[0039] In some embodiments, the first locking member 24 may also be an elastic gripper disposed on the guide housing 21, which locks the position of the pusher 22 by elastically abutting against the pusher 22.

[0040] In this embodiment, the fixing component 2 further includes a second locking member 25, which passes through the guide housing 21 and abuts against the base 1 to lock the position of the guide housing 21. When the fixing component 2 is adjusted to a suitable position so that the pusher 22 can elastically abut against the rectangular ring product 100, the second locking member 25 can be used to lock the guide housing 21. This allows the operator to move only the pusher 22 when changing the rectangular ring product 100, without frequently moving the guide housing 21, improving efficiency and ensuring the accuracy of the guide housing 21's position during CNC machining, thus improving stability.

[0041] Specifically, the second locking element 25 can be a locking screw, which passes through the guide housing 21 and is threadedly connected to it. The operator can lock the position of the guide housing 21 by rotating the locking screw so that the end of the locking screw abuts against the base 1.

[0042] In some embodiments, the second locking member 25 may also be an elastic gripper disposed on the guide housing 21, which locks the position of the guide housing 21 by elastically abutting against the guide housing 21.

[0043] In this embodiment, a slider 27 is provided at the bottom of the guide housing 21, and a guide groove 11 is provided on the base 1 along the first direction. The slider 27 is slidably disposed in the guide groove 11 to ensure the stability of the fixing component 2 during the movement process, and also to ensure the stability of the relative position of the two sets of fixing components 2, so as to avoid misalignment that causes the rectangular ring product 100 to be shifted by force and affect stability.

[0044] Preferably, the slider 27 is a trapezoidal block, the guide groove 11 is a trapezoidal groove, and the opening width of the guide groove 11 is smaller than the bottom width of the guide groove 11. This structure can prevent the slider 27 from disengaging from the guide groove 11, thus improving the stability of the guide housing 21 during movement.

[0045] Preferably, the slider 27 is a T-shaped block and the guide groove 11 is a T-shaped groove. This structure can also prevent the slider 27 from disengaging from the guide groove 11, thus improving the stability of the guide housing 21 during movement.

[0046] To facilitate the assembly of the fixing component 2, the guide housing 21 includes an upper cover 212 and a bottom housing 211. The upper cover 212 and the bottom housing 211 are detachably connected. The pusher 22 and the elastic member 26 are both disposed between the upper cover 212 and the bottom housing 211. The first locking member 24 is disposed on the upper cover 212 and the second locking member 25 is disposed on the bottom housing 211.

[0047] like Figure 1 and Figure 2 As shown, the fixing fixture includes two fixing mechanisms. One fixing mechanism has two sets of fixing components 2 that fix the rectangular ring product 100 in the first direction, and the other fixing mechanism has two sets of fixing components 2 that fix the rectangular ring product 100 in the second direction (Y direction in the figure). The first direction and the second direction are perpendicular to each other to ensure the stability of the rectangular ring product.

[0048] Example 2 This embodiment is based on Embodiment 1, and the structure of the fixing component 2 has been improved.

[0049] like Figures 5-8 As shown, in this embodiment, the guide housing 21 includes a sliding seat 215 and a rotating housing 216. The rotating housing 216 is rotatably disposed on the sliding seat 215, and the pusher 22 is slidably disposed on the rotating housing 216. When the pusher 22 extends outward from the rotating housing 216, the fixing component 2 is in an internally fixed state (e.g., ...). Figure 5 As shown), when the pusher 22 extends inward from the rotating housing 216, the fixing component 2 is in an externally fixed state (as shown). Figure 6 (As shown).

[0050] In other words, the fixing component 2 uses the rotation of the rotating shell 216 on the sliding seat 215 to change the orientation of the pusher 22, thereby switching the fixing component 2 between the inner fixing state and the outer fixing state. Specifically, when fixing a large-sized rectangular ring product 100, the rotating shell 216 can be rotated to make the pusher 22 extend outward, switching the fixing component 2 to the inner fixing state, then the distance between the two sets of fixing components 2 is reduced, and the rectangular ring product 100 is fitted outside the two sets of fixing components 2. At this time, the pusher 22 abuts against the inner side of the rectangular ring product 100. When fixing a small-sized rectangular ring product 100, the rotating shell 216 can be rotated to make the pusher 22 extend inward, switching the fixing component 2 to the outer fixing state, then the distance between the two sets of fixing components 2 is increased, and the rectangular ring product 100 is placed inside the two sets of fixing components 2. At this time, the pusher 22 abuts against the outer side of the rectangular ring product 100.

[0051] In this embodiment, the rotating shell 216 includes an upper cover 212 and a bottom shell 211, which are detachably connected. The pushing member 22 and the elastic member 26 are both disposed between the upper cover 212 and the bottom shell 211. The first locking member 24 is disposed on the upper cover 212, and the second locking member 25 is disposed on the sliding seat 215.

[0052] like Figure 7 and Figure 8 As shown, the sliding seat 215 includes a locking part 2151 and a rotating platform 2152. The locking part 2151 is provided with a second locking member 25, which is configured to lock the position of the sliding seat 215. The top surface of the rotating platform 2152 is higher than the second locking member 25, and the rotating shell 216 is rotatably mounted on the rotating platform 2152. It is understood that the height of the second locking member 25 may interfere with the rotation of the rotating shell 216. However, by using the rotating platform 2152 to raise the rotating shell 216, interference can be avoided, making it easier for the operator to smoothly rotate the rotating shell 216 to switch the state of the fixed component 2.

[0053] In this embodiment, since the pusher 22 extends from the guide housing 21 in a single direction, it is only necessary to provide an elastic member 26 on one side of the pusher 22, and the driving part 221 of the pusher 22 only serves as a limit.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
