Description

Technical Field

[0001] This utility model belongs to the field of tooling and fixture technology, specifically relating to a clamping tooling for pressing parts during the bonding and curing process, with adjustable pressure. Background Technology

[0002] In some equipment manufacturing processes, there is an assembly process where two parts, such as bushings (or shafts), are bonded to a housing part using epoxy resin. Specifically, the housing part has a cylindrical section, and the bushing (or shaft) part is fitted into this cylindrical section. Epoxy resin adhesive is applied to the circumferential outer wall of the bushing (or shaft) part, bonding it to the housing part after insertion. During the bonding process, continuous pressure is required to keep the two bonded parts in place, ensuring they remain in a fixed position and preventing axial displacement due to volume changes during adhesive curing, which could affect assembly accuracy.

[0003] For the two parts that need to be bonded together, there is a lack of dedicated clamping fixtures during the bonding assembly. Spring clamps are often used for clamping and fixing. However, with the increase of usage time and the inconsistency of personnel operation, there are often cases where the clamping is not in place, resulting in poor stability. This is not suitable for bonding and assembling two parts with high assembly precision requirements.

[0004] Therefore, there is an urgent need for a special tooling fixture that can reliably and stably clamp two bonded parts, ensuring that the relative positions of the two bonded parts are stable during bonding and curing, without any skew or displacement, and that the pressure is adjustable and can guarantee stable pressure. Summary of the Invention

[0005] This invention provides a pressure-adjustable bonding and curing clamping fixture, which can solve the problems of inadequate clamping and poor reliability in the existing technology that uses spring clamps for holding and fixing.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is a pressure-adjustable bonding and curing clamping tool, comprising: The base is a vertical cylindrical shape that runs through the top, including a bottom plate and circumferential side plates; A top support block is disposed on the inner top of the base and slides in the vertical direction with the circumferential side plate of the base; A locking component for locking the top support block when the top support block slides into place; An elastic clamping assembly is disposed inside the base and below the top support block; the elastic clamping assembly includes a clamping block and a vertically retractable elastic component; the clamping block is located below the elastic component, forming a clamping space between it and the bottom plate of the base for accommodating the adhesive parts assembly to be cured; the elastic component is clamped between the top support block and the clamping block.

[0007] The base, the top support block, the locking component, the pressure block, and the elastic component are all independent components and can be detached from each other.

[0008] The elastic clamping component is coaxially arranged with the top support block.

[0009] The upper positioning part and the lower positioning part of the elastic component are respectively formed on the center of the bottom surface of the top support block and the center of the top surface of the pressure block for positioning the elastic component.

[0010] A part positioning part is formed on the center of the bottom surface of the pressure block, and a part positioning part is formed on the bottom plate of the base for positioning the adhesive part assembly to be cured. The positioned adhesive part assembly to be cured is coaxial with the top support block.

[0011] The locking component is a shoulder screw. A horizontal threaded hole is formed on the side of the top support block, and a vertically extending adjustment elongated hole is formed on the circumferential side plate of the base. The shoulder screw passes through the adjustment elongated hole and is threaded into the horizontal threaded hole to fasten the top support block and the circumferential side plate of the base to achieve locking.

[0012] A through portion is formed on the circumferential side plate of the base for placing the assembly of adhesive parts to be cured into the clamping space through the through portion.

[0013] The top support block is a cylinder, and the circumferential side plate of the base is an arc-shaped side plate adapted to the top support block.

[0014] Compared with the prior art, the present invention has the following advantages and positive effects: This utility model relates to an adjustable pressure bonding and curing clamping fixture. In use, the assembly of parts to be cured is placed in the clamping space within the base. A pressure source is used to press down on the top support block, causing it to slide downwards relative to the base. This, in turn, presses down on the lower elastic clamping component, compressing the elastic element and clamping the assembly of parts to be cured. Once the target pressure is reached, the top support block can be locked using a locking component. This ensures that the elastic clamping component maintains the target pressure even after the pressure source is removed, achieving stable and reliable clamping of the assembly of parts to be cured and improving the bonding and assembly accuracy of the assembly. Simultaneously, the clamping force is adjustable, enhancing the fixture's versatility and flexibility of use. Attached Figure Description

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Reference Figures 1 to 6 In some embodiments of this utility model, a pressure-adjustable bonding and curing clamping fixture 1 is proposed to clamp the two parts during the adhesive curing stage after they are bonded together, until the adhesive is completely cured. For ease of description, the whole consisting of the two parts in this stage is referred to as the bonded parts group 2 to be cured.

[0021] by Figure 5 and Figure 6 As shown in the example, the bonding parts group 2 to be cured includes a bushing (or shaft) part 2.1 and a housing part 2.2. A cylindrical part 2.3 is formed on the housing part 2.2. The bushing (or shaft) part 2.1 is adapted to be inserted into the cylindrical part 2.3 of the housing part 2.2. Epoxy resin adhesive is coated on the circumferential outer wall of the bushing (or shaft) part 2.1 to achieve bonding between the bushing (or shaft) part 2.1 and the housing part 2.2 after the bushing (or shaft) part 2.1 is inserted into place.

[0022] In some embodiments of this utility model, such as Figures 1 to 6 As shown, the pressure-adjustable adhesive includes a base 10, a top support block 20, a locking component 30, and an elastic clamping assembly 40.

[0023] Among them, the base 10 is the basic part of the entire pressure adjustable bonding and curing clamping fixture 1. It is a vertical cylinder with the upper end through, including a base plate 11 and a circumferential side plate 12. The inner wall of the circumferential side plate 12 is a vertical inner wall.

[0024] The top support block 20 is located at the inner top of the base 10 and slides vertically with the circumferential side plate 12 of the base 10. That is, the top support block 20 can slide up and down relative to the base 10 in the vertical direction. The circumferential side plate 12 of the base 10 guides the sliding of the top support block 20 to ensure the verticality of the sliding of the top support block 20 and avoid skewing.

[0025] The locking component 30 is used to lock the top support block 20 when it slides into place, so that the top support block 20 remains in the position after sliding into place.

[0026] The elastic clamping assembly 40 is disposed inside the base 10 and located below the top support block 20. The elastic clamping assembly 40 includes a pressure block 41 and an elastic member 42 that can be vertically extended and deformed. The pressure block 41 is located below the elastic member 42, and a clamping space 50 is formed between it and the bottom plate 11 of the base 10. The clamping space 50 is used to accommodate the adhesive parts assembly 2 to be cured. The elastic member 42 is clamped between the top support block 20 and the pressure block 41. The pressure on the top support block 20 is transmitted to the adhesive parts assembly 2 to be cured through the elastic clamping assembly 40, thereby clamping the adhesive parts assembly 2 to be cured.

[0027] In some embodiments of this utility model, the pressure-adjustable bonding and curing clamping fixture 1 is used such that the bonding parts assembly 2 to be cured is placed in the clamping space 50 within the base 10, the elastic clamping component 40 is positioned above the bonding parts assembly 2 to be cured, and the top support block 20 is positioned above the elastic clamping component 40. A pressure source (such as a press, with a digital display pressure gauge) is used to vertically press down on the top support block 20, causing it to slide downward relative to the base 10, thereby pressing down on the elastic clamping component 40, compressing the elastic component 42, and pressing the clamping block 41 against the bonding parts to be cured. Assembly 2; After reaching the target pressure, the top support block 20 can be locked by the locking component 30, so that the elastic clamping component 40 can still maintain the target pressure after the pressure source is removed, so as to achieve stable and reliable clamping of the bonding parts assembly 2 to be cured, and improve the assembly accuracy of the bonding parts assembly; by pressing down the top support block 20 to different positions, the locking component 30 can be adjusted to different locking positions accordingly, so as to achieve different pre-tightening pressures, realize pressure adjustment, meet the different curing pressure requirements of different bonding parts assemblies 2 to be cured, and improve the versatility and flexibility of tooling.

[0028] In some embodiments of this utility model, the top support block 20 is a cylinder, and the circumferential side plate 12 of the base 10 is an arc-shaped side plate adapted to the top support block 20 or a cylindrical side plate.

[0029] In some embodiments of this utility model, the pressure-adjustable bonding and curing clamping fixture 1 has a split structure. The base 10, top support block 20, locking component 30, pressure block 41, and elastic component 42 are all independent components that can be disassembled and replaced. For example, before locking, the top support block 20 is simply placed inside the base 10 and has only a sliding fit with the circumferential side plate 12 of the base 10, without any interconnection structure; the top support block 20 and the elastic clamping component 40 are simply stacked on top of each other and also have no interconnection structure; in use, the bonding parts group 2 to be cured is first placed in the clamping space 50 inside the base 10, and then the elastic clamping component 40 and the top support block 20 are stacked in sequence.

[0030] By setting the pressure-adjustable bonding and curing clamping fixture 1 to the aforementioned split structure, it can meet the bonding and curing assembly requirements of parts of different sizes, offering multiple uses and good adaptability. For example, for bonding parts assemblies 2 of different heights to be cured, matching can be achieved by replacing the elastic components 42 with different strokes; for bonding parts assemblies 2 of different diameters to be cured, matching can be achieved by replacing the base 10 and top support block 20 with different diameters.

[0031] In some embodiments of this utility model, a pressure source positioning part (not shown) is formed at the center of the top surface of the top support block 20. By providing a pressure source positioning part on the top support block 20, and with the pressure source positioning part located at the center of the top surface of the top support block 20, the pressure point of the pressure source can be positioned at the center of the top support block 20. This facilitates uniform pressure application to the top support block 20, ensures vertical pressure on the bonding parts 2 to be cured, and avoids relative displacement or skewness of the two bonded parts.

[0032] Specifically, the pressure source positioning part can be a positioning groove, etc.

[0033] In some embodiments of this utility model, the elastic pressing component 40 and the top support block 20 are coaxially arranged. This coaxial arrangement of the elastic pressing component 40 and the top support block 20 also helps to ensure that the bonding parts 2 to be cured are subjected to vertical pressure, thus avoiding relative displacement and skewness of the two bonded parts.

[0034] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, an upper positioning part 21 of the elastic component is formed on the center of the bottom surface of the top support block 20, and a lower positioning part 43 of the elastic component is formed on the center of the top surface of the pressure block 41. This part can be used to position the elastic component 42 and, correspondingly, the pressure block 41. This helps to ensure that the elastic pressing assembly 40 and the top support block 20 remain coaxial. In addition, the top support block 20 slides with the circumferential side plate 12 of the base 10, and the circumferential side plate 12 of the base 10 positions the top support block 20. Thus, both the top support block 20 and the elastic pressing assembly 40 can be well positioned, improving the pressing stability of the adhesive parts assembly 2 to be cured, and thereby improving the assembly accuracy of the adhesive parts assembly.

[0035] The upper positioning part 21 and the lower positioning part 43 of the elastic component can be positioning protrusions or positioning grooves. The elastic component 42 is a straight spring, and its two ends are respectively sleeved on the upper positioning part 21 and the lower positioning part 43 of the elastic component to achieve positioning.

[0036] In some embodiments of this utility model, such as Figures 2 to 4As shown, an upper positioning part 44 is formed on the center of the bottom surface of the pressure block 41, and a lower positioning part 13 is formed on the bottom plate 11 of the base 10. The upper positioning part 44 and the lower positioning part 13 are used to jointly position the adhesive part group 2 to be cured. After positioning, the adhesive part group 2 to be cured is coaxial with the top support block 20 to achieve stable and precise pressing.

[0037] The upper positioning part 44 and the lower positioning part 13 of the part can be positioning protrusions or positioning grooves, and no specific restrictions are imposed here.

[0038] In some embodiments of this utility model, such as Figures 2 to 4 As shown, the locking component 30 is a shoulder screw. A horizontal threaded hole 22 is formed on the side of the top support block 20, and a vertically extending adjustment elongated hole 14 is formed on the circumferential side plate 12 of the base 10. The shoulder screw passes through the adjustment elongated hole 14 and engages with the horizontal threaded hole 22, thus securing the top support block 20 to the circumferential side plate 12 of the base 10. That is, when the target pressure is reached, tightening the shoulder screw secures the top support block 20 to the circumferential side plate 12 of the base 10, thus locking it in place.

[0039] Specifically, the adjusting elongated hole 14 is located on the upper part of the circumferential side plate 12 of the base 10. It can be a rectangular hole with a width that matches the outer diameter of the stud of the shoulder screw, so as to limit the shoulder screw in the left and right directions. The top end of the adjusting elongated hole 14 can extend through the top edge of the circumferential side plate 12 of the base 10. This allows the shoulder screw to be inserted into or removed from the adjusting elongated hole 14 from the top through end. When not locked, the shoulder screw and the top support block 20 can be kept in a relatively loose threaded connection state. The shoulder screw slides down with the top support block 20 until the target pressure is reached, and then it is tightened and locked. This is convenient to operate and does not require separate placement of the shoulder screw, thus preventing its loss.

[0040] In some embodiments of this utility model, such as Figures 1 to 4 As shown, a through portion 15 is formed on the circumferential side plate 12 of the base 10, which is used to place the adhesive parts 2 to be cured into the clamping space 50 through the through portion 15, thereby facilitating the placement of the adhesive parts 2 to be cured and also facilitating the observation of the pressing and curing state.

[0041] Similarly, the top of the through section 15 can penetrate the top edge of the circumferential side plate 12 of the base 10, which not only facilitates the placement of the bonding parts group 2 with a smaller height to be cured, but also facilitates the placement of the bonding parts group 2 with a larger height to be cured, further improving the tooling versatility and flexibility of use.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
