Description

Technical Field

[0001] This utility model relates to the field of mounting equipment, specifically a pretreatment mounting bracket for PVD. Background Technology

[0002] In the field of physical vapor deposition (PVD) technology, the pretreatment process plays a decisive role in the final coating quality of the workpiece. PVD pretreatment fixtures are mainly used to fix the hangers on the workpieces during the physical vapor deposition pretreatment process, so that the workpieces maintain accurate position and posture during the processing and prevent them from moving, shaking or tipping over. By using fixtures, multiple workpieces can be pretreated at the same time (such as grinding or spray coating), which is convenient for batch processing, thereby reducing the time and cost of processing a single workpiece and improving the overall production efficiency.

[0003] Given the relatively large number of coated products that need to be mounted on the racks, the racks are often designed to be tall and long in order to accommodate and process these products. When these tall and vertically mounted racks are placed on conventional fixed racks for physical vapor deposition pretreatment steps, the products located at the top of the racks become difficult to pretreatment effectively. When fine grinding or coating spraying is required on these products, the operator's operating range is limited, making it difficult to ensure the processing quality of the products at the top.

[0004] Therefore, we provide a pretreatment fixture for PVD. Utility Model Content

[0005] The main purpose of this utility model is to provide a pretreatment fixture for PVD, which can effectively solve the problem mentioned in the background art that products located at the top of the bracket are difficult to pre-treat effectively. When these products need to be finely polished or coated, the operator's operating range is limited, making it difficult to ensure the treatment quality of the top products.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A pretreatment fixture for PVD includes a fixture frame. Each upper side of the fixture frame has a retaining ring fixedly connected to it, and the other upper side of the fixture frame has a rotating mechanism. The rotating mechanism includes a fixed plate fixedly mounted on the fixture frame. Each fixed plate has a rotating disk nested and movably connected to one side, and a ball bearing for reducing friction is fitted between the rotating disk and the fixed plate. Each rotating disk has a rotating shaft fixedly mounted on one side, and the rotating shaft is movably connected through the upper part of the fixture frame. Each rotating shaft has a chuck for locking and fixing on one side. Each rotating disk has a fixed rod fixedly mounted in the middle, and each fixed rod has a telescopic rod movably fitted inside it. The telescopic rod has equidistant locking holes for locking and fixing. Each fixed rod has an adjusting bolt fitted on one side, and the adjusting bolt and the locking holes are aligned and fitted together.

[0008] In the above scheme, preferably, support rods are fixedly installed at both ends of the lower part of the fixed frame, casters with locking mechanisms are installed at the four lower corners of the fixed frame, and connecting rods are fixedly installed between the fixed frames.

[0009] In the above scheme, preferably, one end of the telescopic rod and the fixed rod are provided with a movable groove for providing sliding space, and the movable groove is provided with equidistant teeth. Multiple fixing mechanisms are movably installed on the inner side of the movable groove.

[0010] In the above scheme, preferably, the fixing mechanism includes a slider that is fitted and movably installed in the movable groove, and fixing plates are attached to both sides of the slider, and the fixing plates are engaged with the locking teeth on the movable groove.

[0011] In the above scheme, preferably, a symmetrically arranged fixed clamping plate is fitted and movably installed on one side of the slider, and a mounting frame is fitted and installed on the inner side of each fixed clamping plate, and a clamp for fixing the coated product is installed at equal intervals on each mounting frame.

[0012] In the above scheme, preferably, a fixing bolt is movably installed on one of the fixing clamps, and a wing nut is movably installed on the fixing bolt, and the fixing bolt is fixedly connected to the other fixing clamp through the wing nut.

[0013] In the above scheme, preferably, one side of the rotating shaft is polygonal, and the inner side of the chuck is fitted to one side of the rotating shaft, and the chuck and the retaining ring are engaged.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This type of PVD pretreatment mounting bracket is equipped with a rotating mechanism, telescopic rod, and fixed rod. When the mounting bracket is too high and inconvenient for pretreatment, the telescopic rod or fixed rod can be manually pushed to rotate the rotating disk and adjust it to a horizontal position before lowering the mounting bracket, which facilitates the physical vapor deposition pretreatment of the product. If different length mounting brackets need to be installed, the adjusting bolts can be removed, the telescopic rod can be adjusted within the range of the fixed rod, and then the fixed rod can be re-embedded and locked to adapt to different length mounting brackets, facilitating the physical vapor deposition pretreatment of the product.

[0016] This type of PVD pretreatment fixture has a structure with a movable groove and a fixing mechanism. When it is necessary to adjust the position of the fixing mechanism on the telescopic rod and the fixed rod, the fixing plates on both sides of the slider are pulled out from the locking teeth on the movable groove. Then, the position of the fixing mechanism on the telescopic rod and the fixed rod is adjusted. After the fixing mechanism is adjusted to the appropriate position, the fixing plates are reinserted into the movable groove and fit against both sides of the slider. The fixing plates are then engaged with the locking teeth to fix the fixing mechanism on the telescopic rod and the fixed rod after adjustment, so as to facilitate the adjustment of the distance between the mounting brackets.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-6 As shown, in this embodiment, a pretreatment fixture for PVD is provided. Each side of the fixture 1 has a retaining ring 101 fixedly connected to its upper side. A rotating mechanism 5 is installed on the other side of the fixture 1. The rotating mechanism 5 includes a fixed disk 503 fixedly mounted on the fixture 1. A rotating disk 504 for rotation is nested and movably connected to one side of the fixed disk 503. A ball bearing 505 for reducing friction is fitted between the rotating disk 504 and the fixed disk 503. A rotating shaft 501 is fixedly mounted to one side of the rotating disk 504, and the rotating shaft 501 is movably connected through and fitted to the upper part of the fixture 1. One side of 01 is fitted with a chuck 502 for locking and fixing. The middle of the rotating disk 504 is fixedly installed with a fixing rod 7. The fixing rod 7 is fitted with a telescopic rod 6 inside it. The telescopic rod 6 is provided with equidistant locking holes 601 for locking and fixing. One side of the fixing rod 7 is fitted with an adjusting bolt 701. The adjusting bolt 701 and the locking hole 601 are aligned and fitted. One side of the rotating shaft 501 is polygonal. The inner side of the chuck 502 is in contact with one side of the rotating shaft 501. The chuck 502 and the retaining ring 101 are engaged.

[0027] Specifically, with this configuration, during use, the rotating mechanism 5 is mounted on the fixed frame 1 via the rotating shaft 501 and the fixed plate 503. The ball bearing 505 reduces the friction between the fixed plate 503 and the rotating plate 504 during rotation. By sliding the chuck 502 outwards, the chuck 502 is released from engagement with the retaining ring 101, thereby releasing the fixing of the rotating shaft 501 to the fixed frame 1 via the chuck 502 and retaining ring 101. This allows the rotating shaft 501 to be engaged within the fixed frame 1 for limited rotation under external force. When the mounting frame 8 is too high to facilitate pre-processing of the product, the telescopic rod 6 or the fixed rod 7 can be manually pushed to allow the rotating plate 504 to rotate around the rotating shaft 501. The mounting bracket 1 is rotated to adjust the telescopic rod 6 and the fixed rod 7 from a vertical state to a horizontal state. Then, the hanger 8 installed between the telescopic rod 6 and the fixed rod 7 is lowered horizontally to perform physical vapor deposition pretreatment on the product on the fixture 9. When hangers 8 of different lengths are installed between the telescopic rod 6 and the fixed rod 7, the range of the telescopic rod 6 within the fixed rod 7 is adjusted by removing the adjusting bolt 701 from the fixed rod 7. After adjustment, the adjusting bolt 701 is re-embedded into the fixed rod 7 and fitted through the locking hole 601 to fix the telescopic rod 6 in place, thereby adapting to hangers 8 of different lengths to facilitate product pretreatment before physical vapor deposition.

[0028] like Figure 1 and Figure 2 As shown, in this embodiment, support rods 2 are fixedly installed at both ends of the lower part of the fixed frame 1, casters 3 with locking mechanisms are installed at the four corners of the lower part of the fixed frame 1, and connecting rods 4 are fixedly installed between the fixed frames 1.

[0029] Specifically, through this configuration, the support rod 2 can enhance the bottom support stability of the fixed frame 1 to prevent the fixed frame 1 from tilting when bearing weight. The casters 3 with locking mechanisms facilitate the movement of the fixed frame 1 in the workshop. After locking, the position of the fixed frame 1 can be kept stable during the pre-processing process. The connecting rod 4 connects the two side structures of the fixed frame 1, further improving the rigidity of the overall frame.

[0030] like Figures 2-6 As shown, in this embodiment, one end of the telescopic rod 6 and the fixed rod 7 are provided with a movable groove 10 for providing sliding space, and the movable groove 10 is provided with equidistant teeth. Multiple fixing mechanisms 11 are fitted and movably installed on the inner side of the movable groove 10. The fixing mechanism 11 includes a slider 1101 fitted and movably installed in the movable groove 10. Fixing plates 1102 are attached to both sides of the slider 1101, and the fixing plates 1102 are engaged with the teeth on the movable groove 10.

[0031] Specifically, with this configuration, the movable groove 10 provides a guide track and sliding space for the slider 1101. The locking teeth form an engaging and locking structure with the fixing plates 1102 on both sides of the slider 1101. When it is necessary to adjust the position of the fixing mechanism 11 on the telescopic rod 6 and the fixing rod 7, the fixing plates 1102 on both sides of the slider 1101 are pulled out from the locking teeth on the movable groove 10. Then, the position of the fixing mechanism 11 on the telescopic rod 6 and the fixing rod 7 is adjusted. After the fixing mechanism 11 is adjusted to a suitable position, the fixing plates 1102 are reinserted into the movable groove 10 and fit against both sides of the slider 1101. The engagement of the fixing plates 1102 with the locking teeth fixes the fixing mechanism 11 after adjustment on the telescopic rod 6 and the fixing rod 7.

[0032] like Figures 1-6 As shown, in this embodiment, a symmetrically arranged fixed clamping plate 1103 is fitted and movably installed on one side of the slider 1101. A mounting frame 8 is fitted and installed on the inner side of each fixed clamping plate 1103, and a clamp 9 for fixing the coated product is installed at equal intervals on each mounting frame 8. A fixing bolt 1104 is fitted and movably installed on one of the fixed clamping plates 1103, and a wing nut 1105 is nested and movably installed on the fixing bolt 1104. The fixing bolt 1104 is fitted and fixedly connected to the other fixed clamping plate 1103 through the wing nut 1105.

[0033] Specifically, with this configuration, during use, the symmetrical fixed clamps 1103 form an openable connection structure through the fixed bolts 1104 and the wing nuts 1105. By twisting the wing nuts 1105 on the fixed bolts 1104, the engagement and fixation of the other fixed clamp 1103 can be released. Then, by rotating the fixed bolts 1104, one of the fixed clamps 1103 and the other fixed clamp 1103 can be rotated open on the slider 1101, so that the two ends of the hanger 8 can be put in or taken out. When the product needs to be pre-treated, the product is fixed by the clamps 9 to ensure that the product will not fall off during processing or movement. The hanger 8 is placed in the two fixed clamps 1103 and fixed by the fixed bolts 1104 and the wing nuts 1105. Then, the two ends of the hanger 8 are installed in the fixing mechanism 11 on the telescopic rod 6 and the fixing rod 7.

[0034] Working principle: The use of support rod 2 enhances the support stability of the bottom of the fixed frame 1. The universal wheels 3 equipped with locking mechanism facilitate the movement of the fixed frame 1 in the workshop. Connecting rod 4 connects the two sides of the fixed frame 1, further improving the rigidity of the overall frame. The symmetrical fixed clamps 1103 form an openable connection structure through fixing bolts 1104 and wing nuts 1105. By twisting the wing nuts 1105 on the fixing bolts 1104, the engagement and fixation of the other fixed clamp 1103 can be released. Subsequently, by rotating the fixing bolts 1104, one of the fixed clamps 1103 can be rotated open relative to the other fixed clamp 1103 on the slider 1101, facilitating the insertion or removal of both ends of the hanging frame 8. When it is necessary to perform product inspection... During pre-processing, the product is fixed by clamp 9, and the mounting bracket 8 is placed in two fixing clamps 1103 and fixed by fixing bolts 1104 and wing nuts 1105. Then, the two ends of the mounting bracket 8 are installed in the fixing mechanism 11 on the telescopic rod 6 and the fixing rod 7. The movable groove 10 provides a guide track and sliding space for the slider 1101. The set locking teeth form an engaging locking structure with the fixing plates 1102 on both sides of the slider 1101. When it is necessary to adjust the position of the fixing mechanism 11 on the telescopic rod 6 and the fixing rod 7, the fixing plates 1102 on both sides of the slider 1101 are pulled out from the locking teeth on the movable groove 10, and then the position of the fixing mechanism 11 on the telescopic rod 6 and the fixing rod 7 is adjusted. After positioning, the fixing plate 1102 is reinserted into the movable slot 10 and abuts against both sides of the slider 1101. The fixing plate 1102 engages with the locking teeth to fix the fixing mechanism 11 after adjustment on the telescopic rod 6 and the fixing rod 7. The rotating mechanism 5 is mounted on the fixed frame 1 via the rotating shaft 501 and the fixing plate 503. The ball bearing 505 reduces the friction between the fixing plate 503 and the rotating plate 504 during rotation. By sliding the chuck 502 outwards, the engagement between the chuck 502 and the retaining ring 101 is released, thus releasing the fixing of the rotating shaft 501 to the fixed frame 1 via the chuck 502 and retaining ring 101. This allows the rotating shaft 501 to be engaged within the fixed frame 1 under external force for limited rotation. When the load is mounted... When the height of the frame 8 is too high to facilitate product pretreatment, the telescopic rod 6 or the fixed rod 7 can be manually pushed to rotate the rotating disk 504 around the rotating shaft 501 on the fixed frame 1. This adjusts the telescopic rod 6 and the fixed rod 7 from a vertical to a horizontal state, allowing the hanger 8 installed between the telescopic rod 6 and the fixed rod 7 to be lowered horizontally for physical vapor deposition pretreatment of the product on the fixture 9. When hangers 8 of different lengths are installed between the telescopic rod 6 and the fixed rod 7, the range of the telescopic rod 6 within the fixed rod 7 can be adjusted by removing the adjusting bolt 701 from the fixed rod 7. After adjustment, the adjusting bolt 701 is re-embedded into the fixed rod 7 and fitted through the locking hole 601 to secure the telescopic rod 6 in place.This allows for the adaptation of mounting frames 8 of varying lengths, facilitating product processing prior to physical vapor deposition.
