Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, specifically to an embedded support anti-vibration fixture. Background Technology

[0002] In the machinery manufacturing industry, the rapid development of modern technology has driven the continuous progress and improvement of the industry. Traditional machinery manufacturing processes can no longer meet the development needs of the modern machinery manufacturing industry, so it is necessary to apply the latest modern machinery manufacturing technologies and equipment.

[0003] In the field of IC equipment, there are a large number of small, thin-walled cavity parts with high product value and diverse types. These parts have relatively weak overall rigidity and are prone to deformation during processing. Their top and bottom surfaces are thin, but the parts are relatively large in size. This structural feature causes the cutting tool to vibrate during processing, resulting in the phenomenon of tool chatter.

[0004] Without proper fixture reinforcement, the machining feed rate for these parts will be extremely low, making high-efficiency machining impossible. Furthermore, the tremor phenomenon not only causes part deformation but also leads to dimensional deviations exceeding permissible tolerances, severely impacting machining quality and product yield. Therefore, there is an urgent need to develop a fixture that effectively addresses the tremor and deformation issues during machining of these parts, thereby improving machining efficiency and part quality. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an embedded support anti-vibration fixture. This embedded support anti-vibration fixture provides support by having wedge plate A and wedge plate B contact the top and bottom surfaces of the inner cavity of the thin-walled part, respectively. The vertical distance between the upper and lower surfaces is adjusted by a wedge plate relative position adjustment mechanism, thereby providing stable support for the part during processing, significantly reducing or eliminating the vibration phenomenon caused by the weak rigidity of the part, and improving the stability and accuracy of processing.

[0006] The technical solution of this utility model is as follows:

[0007] An embedded support anti-vibration device includes a wedge plate A, a wedge plate B, and a wedge plate relative position adjustment mechanism. Wedge plate A has an upper plane and an inclined surface A arranged opposite to each other. The upper plane is used to contact the top surface of the inner cavity of a thin-walled part to provide support. Wedge plate B has a lower plane and an inclined surface B arranged opposite to each other. The lower plane is used to contact the bottom surface of the inner cavity of the thin-walled part to provide support. Inclined surface A and inclined surface B have the same slope, and inclined surface B is tightly fitted onto inclined surface A. The wedge plate relative position adjustment mechanism is used to drive or restrict the relative sliding between wedge plate A and wedge plate B to adjust the vertical distance between the upper and lower planes.

[0008] A pad is provided between the lower plane of the wedge plate B and the bottom surface of the inner cavity of the thin-walled part.

[0009] The wedge plate A, wedge plate B, and pad are made of plastic.

[0010] Alternatively, the plastic material may be any one of polyphenylene sulfide, polyimide, polyetheretherketone, or polyetherketoneketone.

[0011] The relative position adjustment mechanism of the inclined wedge plate includes lugs on both sides of the inclined wedge plate A, fixing blocks on both sides of the inclined wedge plate B, and screws. The lugs are provided with through holes, and the fixing blocks are provided with threaded holes corresponding to the through holes. The screws pass through the through holes and engage with the threaded holes.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model discloses an embedded support anti-vibration fixture, which effectively prevents the tremor phenomenon. It provides support by having inclined wedge plate A and inclined wedge plate B contact the top and bottom surfaces of the inner cavity of the thin-walled part, respectively. The vertical distance between the upper and lower surfaces is adjusted by the relative position adjustment mechanism of the inclined wedge plates, thereby providing stable support for the part during the processing, significantly reducing or eliminating the tremor phenomenon caused by the weak rigidity of the part, and improving the stability and accuracy of the processing.

[0014] 2. The present invention discloses an embedded support anti-vibration fixture, which improves processing efficiency. Since the fixture can effectively prevent the trembling of the cutting tool, the processing feed speed can be increased without reducing the speed due to the trembling of the cutting tool, thereby achieving high-efficiency processing and meeting the needs of modern machinery manufacturing industry for high-efficiency production.

[0015] 3. The present invention discloses an embedded support anti-vibration fixture, which improves the processing quality of parts. By reducing the vibration phenomenon, the fixture can significantly reduce the deformation risk of parts during processing, ensure that the part size is within the allowable error range, improve the processing quality and product qualification rate of parts, and meet the requirements of the IC equipment field for high-precision processing of small cavity thin-walled parts.

[0016] 4. The embedded support anti-shock device disclosed in this utility model has strong adaptability. Through the design of the relative position adjustment mechanism of the inclined wedges, it can adapt to thin-walled parts of different sizes and shapes. By adjusting the relative position between the inclined wedges, it can effectively support different parts and has strong versatility and flexibility.

[0017] 5. The embedded support anti-shock device disclosed in this utility model has a reasonable material selection. The inclined wedge plate A, inclined wedge plate B and pad are made of plastic material (such as polyphenylene sulfide, polyimide, polyether ether ketone or polyether ketone ketone). These materials have good wear resistance, heat resistance and chemical stability, and can maintain stable performance during processing. At the same time, the weight of the device is reduced, which makes it easy to operate and install and does not easily scratch the parts. Attached Figure Description

[0028] like Figure 1 and Figure 2 As shown, the embedded support defibrillator includes the following components:

[0029] Wedge plate A1: Made of special plastic materials such as polyphenylene sulfide, for example Figure 4 As shown, it has an upper plane 11 and an inclined plane A12 arranged opposite to each other; the upper plane 11 is used to contact the top surface of the inner cavity of the thin-walled part 5 to provide stable support; the inclined wedge plate A1 is provided with ear blocks 13 on both sides, and the ear blocks 13 are provided with through holes 131; the slope angle design of the inclined plane A12 is based on the friction coefficient calculation between the material of the inclined wedge plate and the contact surface inclined plane B, to ensure that the fixture has a self-locking effect during the tension adjustment and processing force process, and will not slip due to gravity or cutting force.

[0030] Wedge plate B2: Made of special plastic materials such as polyimide, for example... Figure 5 As shown, it has a lower plane 21 and an inclined plane B22 arranged opposite to each other. The lower plane 21 is used to contact the bottom surface of the inner cavity of the thin-walled part 5, or to indirectly contact it through the pad 3 to provide support. The slope of the inclined plane B22 is the same as that of the inclined plane A12, and it fits tightly against the inclined plane A12 to form a mating wedge surface. The inclination angle of the inclined plane B22 corresponds strictly to that of the inclined plane A12. The friction coefficient is calculated to ensure that there is sufficient static friction when the two inclined planes are in contact, so as to prevent the fixture from being displaced or slipping due to vibration or external force during the processing.

[0031] Pad 3: Made of special plastic material such as polyetheretherketone (PEEK), machined according to the internal cavity dimensions of the part, such as... Figure 6 As shown, it is placed between the lower plane 21 of the inclined wedge plate B2 and the bottom surface of the inner cavity of the thin-walled part 5, in order to increase the contact area between the fixture and the part, improve the support stability, and enhance the versatility of the fixture.

[0032] Screw 4: It is used to pass through the through hole 131 on the ear block 13 and engage with the threaded hole 231 on the fixing block 23 to drive or restrict the relative sliding between the wedge plate A1 and the wedge plate B2, thereby adjusting the thickness of the fixture.

[0033] This fixture is designed based on the principle of relative motion of wedge plates. By rotating screw 4, the inclined wedge plate A1 and the inclined wedge plate B2 slide relative to each other along the inclined surface, thereby changing the overall thickness of the fixture.

[0034] The slopes of inclined planes A12 and B22 are designed reasonably, as follows:

[0035] The calculation basis for the inclined plane angle is as follows: Based on the static friction coefficient μ of the inclined wedge plate material such as polyphenylene sulfide or polyimide, the inclined plane angle θ is designed to make tanθ < μ, so as to ensure that the inclined wedge plate will not fail to self-lock due to gravity or cutting force components under stress.

[0036] The method of using this embedded support anti-gastrointestinal device is as follows:

[0037] 1. Assemble the fixture: Assemble the wedge plate A1, wedge plate B2 and pad 3 together according to the design requirements, ensuring that the inclined surface A12 and the inclined surface B22 fit tightly without gaps or misalignment.

[0038] 2. Place the fixture into the cavity of the part: Place the assembled fixture into the cavity of the thin-walled part 5 to be processed, ensuring that the upper plane 11 is in contact with the top surface of the cavity and the lower plane 21 or the lower surface of the pad 3 is in contact with the bottom surface of the cavity.

[0039] 3. Adjust the thickness of the fixture: Use a screwdriver or other tools to rotate screw 4 so that the wedge plate A1 and the wedge plate B2 slide relative to each other along the inclined plane, gradually increasing the thickness of the fixture until the fixture tightens the inner cavity of the part. At this time, the self-locking effect of the inclined plane takes effect, and the fixture and the inner cavity of the part form a stable support.

[0040] 4. Machining: After the fixture tightens the inner cavity of the part, the part can be machined. Since the fixture provides stable support through the inclined plane self-locking and the pad support, the occurrence of tool chatter can be effectively avoided during the machining process, thereby improving machining efficiency and part quality.

[0041] 5. Disassembling the fixture: After machining, rotate screw 4 in the opposite direction to reduce the thickness of the fixture, release the self-locking effect of the inclined plane, and make it easier to remove the fixture from the inner cavity of the part.

[0042] This embedded support anti-vibration fixture significantly suppresses tremor: the fixture strengthens the overall strength of the part by tightening the inner cavity of the part, effectively avoiding the problem of tremor deformation during processing, and improving the part dimensional qualification rate to over 98%; it is convenient and efficient to operate: the fixture is easy to clamp, simple to use, and requires low operator skills, making it suitable for batch processing; it has enhanced versatility: the pad can be customized according to the inner cavity size of the part, and combined with the self-locking design of the inclined angle, the fixture can be adapted to small cavity thin-walled parts of various sizes.
