Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically to an electrophoretic coating lifting equipment. Background Technology

[0002] Electrophoretic coating is a coating method that uses an external electric field to cause pigments and resin particles suspended in an electrophoretic solution to migrate directionally and deposit onto the surface of a substrate, which is one of the electrodes. During the electrophoretic coating process, a coating hanger is used to place the parts to be coated into the electrophoretic pool, and the parts are removed after electrophoresis is complete.

[0003] Based on the above, the inventors have discovered the following problems: In the current electrophoretic coating hangers, the distance between adjacent hangers for placing parts is fixed and cannot be adjusted. When the part size is large, the parts on adjacent hangers may be too close together, resulting in uneven electric field distribution, which in turn causes uneven coating thickness on the part surface, thereby reducing the electrophoretic effect of the part.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an electrophoretic coating hanger in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide an electrophoretic coating hanger to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] An electrophoretic coating hanger includes a lifting bracket body and an adjustment mechanism. The adjustment mechanism includes a square box, the top surface of which is fixedly connected to the inner top surface of the lifting bracket body. A rack plate is provided on the back of the square box, and the top surface of the rack plate is fixedly connected to the inner top surface of the lifting bracket body. A smooth rod is installed inside the square box, and several slide blocks are slidably connected to the outside of the smooth rod. A cavity is opened inside the slide block, and a first sliding groove is opened on both sides of the cavity. A sliding block is slidably connected between a pair of first sliding grooves. One end of the sliding block is toothed and extends through the slide block to the outside, engaging with the rack plate. A pull rod is installed at the end of the sliding block away from the rack plate, and the pull rod extends through the slide block to the outside, engaging with a through hole in the slide block. Furthermore, both the pull rod and the sliding block have a "T" shaped cross-section. A first spring is sleeved on the outside of the pull rod, and the two ends of the first spring are fixedly connected to the end of the sliding block away from the rack plate and the inner wall of the cavity, respectively.

[0008] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperation of the pull rod and the first spring, when the pull rod is pulled outward, the sliding block retracts into the interior of the slide block, causing the toothed end of the sliding block to separate from the rack plate, thereby facilitating the subsequent sliding of the slide block, allowing it to slide on the smooth rod, and adjusting the position of the slide block. By setting the first spring, the sliding block returns to its original position under the elastic force of the first spring.

[0009] Furthermore, the bottom end of the slide is provided with a placement assembly, which includes a mounting rod. The upper end of the mounting rod is fixedly connected to the bottom end of the slide, and the interior of the mounting rod is hollow. Four mounting seats are installed on the outer side wall of the mounting rod near the upper end, and an adjusting rod is rotatably connected inside each of the four mounting seats.

[0010] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the mounting base and the adjusting rod, there are four mounting bases and four adjusting rods. Since the mounting base and the adjusting rod are rotatably connected, it is convenient to adjust the angle of the adjusting rod.

[0011] Furthermore, each of the adjusting rods has a first connecting seat installed on the side near the mounting rod. The outer wall of the mounting rod has four square grooves near the bottom end, and each of the four square grooves has a second connecting seat inside. The outer wall of the second connecting seat fits into the inner wall of the square groove, and a connecting rod is hinged between the second connecting seat and the first connecting seat. An electric telescopic rod is installed at the upper inner end of the mounting rod, and a connecting plate is installed at the movable end of the electric telescopic rod. The outer wall of the connecting plate fits into the inner wall of the mounting rod, and the outer side of the connecting plate has four grooves, in which the four second connecting seats are respectively installed.

[0012] The beneficial effect of adopting the above-mentioned further solution is that by installing an electric telescopic rod, when the electric telescopic rod works and its movable end retracts, it will drive the connecting plate to move upward inside the mounting rod, so that the second connecting seat in the groove of the connecting plate moves upward inside the square groove, and under the action of the second connecting seat, the connecting rod and the first connecting seat, the four adjusting rods are opened, thereby adjusting the spacing between the parts subsequently hung on the adjusting rod fixing assembly, thereby improving the electrophoresis effect on the parts.

[0013] Furthermore, a fixing component is installed on the side of the adjusting rod away from the mounting rod near the bottom. The fixing component includes a hook seat, one side of which is fixedly connected to the side of the adjusting rod away from the mounting rod. The hook seat has an internal mounting groove, and second sliding grooves are formed on both sides of the internal mounting groove. A blocking seat is slidably connected between a pair of second sliding grooves. The blocking seat has a U-shaped longitudinal section, and the end of the blocking seat away from the mounting groove engages with the end of the hook seat away from the mounting groove. The beneficial effect of this further solution is that by setting the blocking seat, when the blocking seat is pulled upwards, it moves steadily upwards in a straight line within the mounting groove under the action of the two second sliding grooves. This causes the end of the blocking seat away from the mounting groove to no longer engage with the end of the hook seat away from the mounting groove. At this point, the part is hung on the hook seat, and then the blocking seat is released, causing the end away from the mounting groove to re-engage with the end of the hook seat away from the mounting groove, thus blocking the opening at the top of the hook seat and preventing the part from falling off the hook seat during electrophoresis.

[0014] Furthermore, a pair of second springs are installed on one side of the upper end of the shielding seat, and the pair of second springs are fixedly connected to the upper end of the mounting groove at the end away from the shielding seat.

[0015] The advantage of adopting the above-mentioned further solution is that by installing a second spring, it is easier to reset the shield seat under the elastic force of the second spring.

[0016] Furthermore, lifting rings are installed on both sides of the upper end of the hoisting bracket body.

[0017] The beneficial effect of adopting the above-mentioned further solution is that by installing lifting rings at the upper end of the lifting support body, the hooks of the lifting equipment can be connected to the lifting support body through the lifting rings.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This electrophoretic coating hanger has three slides. Through the cooperation of the smooth rod and several slides, when the pull rod is pulled outward, the sliding block retracts into the slide, causing the toothed end of the sliding block to separate from the rack plate. The slide can slide outside the smooth rod, which facilitates the subsequent sliding of the slide on the smooth rod, adjusting the distance between two adjacent slides, and thus adjusting the distance between two adjacent placement components. This avoids the parts on adjacent placement components being too close together, resulting in uneven electric field distribution and uneven coating thickness on the surface of the parts. After the position of the slide is adjusted, a first spring is set. When the pull rod is released, the sliding block returns to its original position under the elastic force of the first spring and the sliding action with the first sliding groove. This causes the rack plate to re-engage with the toothed end of the sliding block inside the slide, so as to lock the position of the slide and prevent the slide from sliding randomly on the smooth rod.

Detailed Implementation

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5This utility model provides a technical solution: an electrophoretic coating hanger, including a hanger body 100 and an adjustment mechanism 200. The adjustment mechanism 200 includes a square box 2001, the top surface of which is fixedly connected to the inner top surface of the hanger body 100. A rack plate 2004 is provided on the back of the square box 2001, the top surface of which is fixedly connected to the inner top surface of the hanger body 100. A smooth rod 2002 is installed inside the square box 2001, and several slide blocks 2003 are slidably connected to the outside of the smooth rod 2002. The interior of component 3 has a cavity, and both sides of the cavity have first sliding grooves. A sliding block 2005 is slidably connected between a pair of first sliding grooves. One end of the sliding block 2005 is toothed and extends through the slide block 2003 to the outside, engaging with the rack plate 2004. A pull rod 2006 is installed at the end of the sliding block 2005 away from the rack plate 2004. The pull rod 2006 extends through the slide block 2003 to the outside and is clearance-fitted with the through hole of the slide block 2003. Both the sliding block 2005 and the pull rod 2006 have a "T" shaped cross-section. A first spring 2007 is sleeved on the outside of the pull rod 2006. The two ends of the first spring 2007 are fixedly connected to the end of the sliding block 2005 away from the rack plate 2004 and the inner wall of the cavity, respectively. Pulling the pull rod 2006 outward causes the sliding block 2005 to retract into the slide block 2003, causing the toothed end of the sliding block 2005 to separate from the rack plate 2004. The slide block 2003 can slide outside the smooth rod 2002, thus facilitating subsequent sliding of the slide block 2003 and allowing it to slide in the smooth rod 2002. Slide the rod 2002 to adjust the distance between two adjacent slide blocks 2003, and then adjust the distance between two adjacent placement components 300. After the position of the slide block 2003 is adjusted, release the pull rod 2006 to allow the sliding block 2005 to return to its original position under the elastic force of the first spring 2007 and the sliding action with the first slide groove. This allows the rack plate 2004 to re-engage with the toothed end of the sliding block 2005 in the slide block 2003, so as to lock the position of the slide block 2003 and prevent the slide block 2003 from sliding freely on the rod 2002.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model provides a technical solution: A placement assembly 300 is provided at the bottom of the slide block 2003. The placement assembly 300 includes a mounting rod 3001. The upper end of the mounting rod 3001 is fixedly connected to the bottom end of the slide block 2003. The interior of the mounting rod 3001 is hollow. Four mounting seats 3002 are installed on the outer wall of the mounting rod 3001 near the upper end. An adjusting rod 3003 is rotatably connected inside each of the four mounting seats 3002. A first connecting seat 3004 is installed on the side of the adjusting rod 3003 near the mounting rod 3001. Four square grooves 3005 are formed on the outer wall of the mounting rod 3001 near the bottom end. A second connecting seat 3006 is provided inside each of the four square grooves 3005. The outer wall of the second connecting seat 3006 fits against the inner wall of the square groove 3005. A connecting rod 3007 is hinged between the second connecting seat 3006 and the first connecting seat 3004. An electric... The movable telescopic rod 3008 has a connecting plate 3009 installed at its movable end. The outer wall of the connecting plate 3009 fits against the inner wall of the mounting rod 3001. The outer side of the connecting plate 3009 has four grooves, and four second connecting seats 3006 are respectively installed in the four grooves. When the movable end of the electric telescopic rod 3008 is retracted, it will drive the connecting plate 3009 to move upward inside the mounting rod 3001. This causes the second connecting seats 3006 in the grooves of the connecting plate 3009 to move upward inside the square grooves 3005. Since the mounting seat 3002 is rotatably connected to the adjusting rod 3003, the four adjusting rods 3003 are opened under the action of the second connecting seats 3006, the connecting rod 3007, and the first connecting seat 3004. This allows for adjustment of the spacing between the parts that are subsequently hung on the fixing assembly 400 on one side of the adjusting rod 3003, thereby improving the electrophoretic effect on the parts.

[0029] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5This utility model provides a technical solution: a fixing component 400 is installed on the side of the adjusting rod 3003 away from the mounting rod 3001 near the bottom. The fixing component 400 includes a hook seat 4001, one side of which is fixedly connected to the side of the adjusting rod 3003 away from the mounting rod 3001. The hook seat 4001 has an installation groove inside, and second sliding grooves are provided on both sides of the installation groove. A blocking seat 4002 is slidably connected between the pair of second sliding grooves. The blocking seat 4002 has a U-shaped longitudinal section, and the end of the blocking seat 4002 away from the installation groove engages with the end of the hook seat 4001 away from the installation groove. A pair of second springs 4003 are installed on one side of the upper end of the blocking seat 4002, and the ends of the pair of second springs 4003 away from the blocking seat 4002 are respectively fixedly connected to the upper end of the installation groove. The lifting bracket body 1... Both sides of the upper end of the 00 are equipped with lifting rings. Pulling the shield 4002 upwards causes it to move steadily upwards in a straight line within the mounting groove under the action of the two second sliding grooves. This causes the end of the shield 4002 away from the mounting groove to no longer engage with the end of the hook seat 4001 away from the mounting groove. At this time, the part is hung on the hook seat 4001. Then, the shield 4002 is released, allowing it to return to its original position under the elastic force of the second spring 4003 and the sliding limit action of the second sliding groove. This causes the end of the shield 4002 away from the mounting groove to re-engage with the end of the hook seat 4001 away from the mounting groove, thus shielding the opening at the upper end of the hook seat 4001 and preventing the part from falling off the hook seat 4001 during electrophoresis. By installing lifting rings at the upper end of the lifting bracket body 100, the hooks of the lifting equipment are connected to the lifting bracket body 100 through the lifting rings.

[0031] Specifically, the working principle of this electrophoretic coating hanger is as follows: During use, adjust the position of the slide block 2003 on the guide rod 2002 according to the size of the part to be electrophoretically coated. Pull the pull rod 2006 outwards, causing the sliding block 2005 to retract inwards from the slide block 2003. Simultaneously, the toothed end of the sliding block 2005 separates from the rack plate 2004, adjusting the distance between two adjacent slide blocks 2003, and thus adjusting the distance between two adjacent placement components 300. Once the position of the slide block 2003 is adjusted, release the pull rod 2006. 6. The sliding block 2005 returns to its original position under the elastic force of the first spring 2007. The rack plate 2004 re-engages with the toothed end of the sliding block 2005 inside the slide block 2003, locking the position of the slide block 2003. Pull the blocking seat 4002 upward, causing it to move steadily upward in a straight line within the mounting groove under the action of the two second sliding grooves. This causes the end of the blocking seat 4002 away from the mounting groove to no longer engage with the end of the hook seat 4001 away from the mounting groove. At this point, the part is hung on the hook seat 4001. Then, the cover seat 4002 is released, allowing it to return to its original position under the elastic force of the second spring 4003. This causes the end of the cover seat 4002 away from the mounting groove to re-engage with the end of the hook seat 4001 away from the mounting groove, thus covering the upper opening of the hook seat 4001 and preventing parts from falling off. When the electric telescopic rod 3008 operates and its movable end retracts, it drives the connecting plate 3009 to move upward inside the mounting rod 3001, causing the second connecting seat in the groove of the connecting plate 3009 to... 3006 moves upward inside the square groove 3005. Under the action of the second connecting seat 3006, the connecting rod 3007 and the first connecting seat 3004, the four adjusting rods 3003 are opened, thereby adjusting the spacing between the parts that are subsequently hung on the fixing assembly 400 on one side of the adjusting rod 3003, thereby improving the electrophoresis effect on the parts. Then, the hook of the hoisting equipment is used to connect to the hoisting bracket body 100 through the lifting ring, so that the hoisting device can be placed into the electrophoresis pool for electrophoresis treatment of the parts.
