Description

Technical Field

[0001] This utility model relates to the field of vacuum coating technology, and in particular to a coating fixture. Background Technology

[0002] Coating is the process of covering the surface of an object with a thin film of metal or other materials. It is widely used to improve the surface hardness, wear resistance, corrosion resistance, or decorative effect of products. The main function of coating fixtures is to fix and support the workpiece to be coated, ensuring its accurate and stable position during the coating process, and helping to improve production efficiency and coating quality.

[0003] Chinese Patent Publication No. CN214218848U, published on 20210917, discloses a coating fixture. The coating fixture includes a fixture body, which forms a coating space extending from the front to the back of the fixture body. Grooves are respectively formed on the two opposite sides of the front of the fixture body. The inner wall of the groove forms a placement area for placing the chip to be coated, and the cross-sectional shape of the inner wall of the groove is V-shaped.

[0004] Existing coating fixtures, such as the one described above, use grooves arranged with opposite sides to form a placement area on the inner wall of the groove. This placement area is used to place the chip to be coated. However, in practice, due to the small contact area between the upper and lower horizontal seats, it is not easy to quickly align the upper and lower horizontal seats. This makes it inconvenient to lock the main frame using the locking rod. Therefore, there is an urgent need to propose a corresponding coating fixture to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a coating fixture in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A coating fixture includes a main frame, the main frame including two sets of upper and lower horizontal seats, each set of upper and lower horizontal seats having a side frame assembly integrated between them, each set of upper and lower horizontal seats having a right-angled groove on its opposite surface, each set of upper and lower horizontal seats having a locking assembly integrated between them, and the upper and lower horizontal seats being fixedly connected by a locking rod.

[0008] Preferably, the side frame assembly includes an inner strip and an outer strip, the outer strip being fitted over the outer side of the inner strip, and the outer wall of the outer strip having an integrated locking part for locking the position of the inner strip.

[0009] Preferably, the locking part includes a positioning rod that is screwed onto the outer wall of the outer sleeve, and the open end of the positioning rod abuts against the outer wall of the inner strip.

[0010] Preferably, a protrusion is fixedly connected to the open end of the inner strip, and both the protrusion and the outer wall of the inner strip are slidably connected to the inner wall of the outer sleeve.

[0011] Preferably, the engaging assembly includes a rectangular sleeve fixedly connected to the bottom of the upper horizontal seat, and a retaining sleeve fixedly connected to the top of the lower horizontal seat, wherein the outer wall of the rectangular sleeve engages with the inner wall of the retaining sleeve.

[0012] Preferably, a sealing gasket is fixedly connected to the bottom of the rectangular sleeve.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. In this application, the rectangular sleeve at the bottom of the upper horizontal seat is inserted into the sleeve at the top of the lower horizontal seat, thus aligning the upper and lower horizontal seats. The locking rod is then passed through the upper horizontal seat and fixed to the lower horizontal seat via screw holes, thereby assembling the main frame as a whole. The right-angled grooves on the upper and lower horizontal seats form a placement space, where the coated chip is placed, ensuring stable subsequent coating processes. The rectangular sleeve and sleeve cooperate to achieve pre-alignment of the upper and lower horizontal seats, improving the ease of assembly and disassembly of the coating fixture.

[0015] 2. In this application, after the upper and lower horizontal seats are fixed, one of the two sets of upper horizontal seats or one set of lower horizontal seats is pulled horizontally. The inner strip slides along the outer sleeve until the coating space in the middle of the coating fixture is adjusted to a suitable size. Then, the positioning rod is rotated to screw it into the outer sleeve. The inner strip is fixed to the outer sleeve through the contact friction between the positioning rod and the inner strip, so that the coating space of the coating fixture can be conveniently adjusted according to the usage requirements.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A coating fixture includes a main frame 1, which includes two sets of upper horizontal seats 101 and lower horizontal seats 102. Side frame assemblies are integrated between the two sets of upper horizontal seats 101 and lower horizontal seats 102. Right-angled grooves 2 are provided on the opposite surfaces of the upper horizontal seats 101 and lower horizontal seats 102. A locking assembly is integrated between the upper horizontal seats 101 and lower horizontal seats 102, and the upper horizontal seats 101 and lower horizontal seats 102 are fixedly connected by a locking rod 3.

[0025] Insert the rectangular sleeve 8 at the bottom of the upper horizontal seat 101 into the retaining sleeve 9 at the top of the lower horizontal seat 102. At this point, the upper horizontal seat 101 and the lower horizontal seat 102 are aligned. Then, pass the locking rod 3 through the upper horizontal seat 101 and fix it to the lower horizontal seat 102 through the screw hole, thus completing the overall assembly of the main frame 1. The right-angled grooves 2 on the upper horizontal seat 101 and the lower horizontal seat 102 form a placement space. The coating chip is placed in this placement space, which ensures the stable progress of the subsequent coating process. The upper horizontal seat 101 and the lower horizontal seat 102 are pre-aligned through the cooperation of the rectangular sleeve 8 and the retaining sleeve 9. This improves the convenience of the overall assembly and disassembly of the coating fixture.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, the side frame assembly includes an inner strip 4 and an outer sleeve 5. The outer sleeve 5 is fitted over the inner strip 4, and the outer wall of the outer sleeve 5 integrates a locking part for locking the position of the inner strip 4. The locking part includes a positioning rod 6 that is screwed into the outer wall of the outer sleeve 5, and the open end of the positioning rod 6 abuts against the outer wall of the inner strip 4. A protrusion 7 is fixedly connected to the open end of the inner strip 4. The protrusion 7 and the outer wall of the inner strip 4 are slidably connected to the inner wall of the outer sleeve 5, which can prevent the inner strip 4 from completely separating from the outer sleeve 5. After the upper horizontal seat 101 and the lower horizontal seat 102 are fixed, one of the two sets of upper horizontal seats 101 or lower horizontal seats 102 is pulled horizontally, and the inner strip 4 slides along the outer sleeve 5 until the coating space in the middle of the coating fixture is adjusted to a suitable size. Then, the positioning rod 6 is rotated to screw into the outer sleeve 5. The inner strip 4 and the outer sleeve 5 are fixed through the contact friction between the positioning rod 6 and the inner strip 4, so that the coating space of the coating fixture can be conveniently adjusted according to the usage requirements.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the engaging assembly includes a rectangular sleeve 8 fixedly connected to the bottom of the upper horizontal seat 101, and a retaining sleeve 9 fixedly connected to the top of the lower horizontal seat 102. The outer wall of the rectangular sleeve 8 engages with the inner wall of the retaining sleeve 9. When the rectangular sleeve 8 at the bottom of the upper horizontal seat 101 is inserted into the retaining sleeve 9 at the top of the lower horizontal seat 102, the upper horizontal seat 101 and the lower horizontal seat 102 are aligned. The rectangular sleeve 8 and the retaining sleeve 9 can form a closed chamber, effectively protecting the locking rod 3.

[0028] Working principle: Insert the rectangular sleeve 8 at the bottom of the upper horizontal seat 101 into the sleeve 9 at the top of the lower horizontal seat 102. At this time, the upper horizontal seat 101 and the lower horizontal seat 102 are aligned. Then, pass the locking rod 3 through the upper horizontal seat 101 and fix it to the lower horizontal seat 102 through the screw hole. This completes the overall assembly of the main frame 1. The right-angled grooves 2 on the upper horizontal seat 101 and the lower horizontal seat 102 form a placement space. The coated chip is combined in this placement space, which can ensure the stable progress of the subsequent coating process of the coated chip. The upper horizontal seat 101 and the lower horizontal seat 102 are pre-aligned by the cooperation of the rectangular sleeve 8 and the sleeve 9. The ease of assembly and disassembly of the coating fixture is improved. After fixing the upper horizontal seat 101 and the lower horizontal seat 102, pull one of the two sets of upper horizontal seats 101 or lower horizontal seats 102 horizontally. The inner strip 4 slides along the outer sleeve 5 until the coating space in the middle of the coating fixture is adjusted to a suitable size. Then, rotate the positioning rod 6 to screw it into the outer sleeve 5. The inner strip 4 is fixed to the outer sleeve 5 through the contact friction between the positioning rod 6 and the inner strip 4. This allows the coating space of the coating fixture to be easily adjusted according to the usage requirements.
