Description

Technical Field

[0001] The utility model relates to the technical field of gantry type electrophoretic coating, in particular to a lifting device for processing gantry type electrophoretic coating equipment. Background Art

[0002] Electrophoretic coating is a common coating process. It uses electrochemical principles to form a uniform, dense, and well-adhesive organic film on the metal surface. It is usually used for surface protection and beautification of metal parts to enhance their corrosion resistance, wear resistance, and appearance quality. During the electrophoretic coating process, the height of the workpiece is adjusted by a lifting device to ensure that the workpiece is in a suitable position during the coating process, thereby ensuring the coating quality of the workpiece.

[0003] The Chinese patent "A stable, anti-falling gantry electrophoretic coating equipment" authorization announcement number "CN 216663270U" cooperates with the lifting plate through the threaded rod, and realizes the up and down movement of the lifting plate under the drive of the driving motor. The lifting process of the placement slot is smoother by pulling the vertical pull rod; the setting of the placement slot solves the problem of insufficient clamping of the workpiece during electrophoresis; through the cooperation of the limit hole and the lifting part, the lifting connection of the placement slot is more stable.

[0004] In the above scheme, a lifting plate and a vertical pull rod are used to realize the up and down movement of the placement trough. When the workpiece is painted and the placement trough is pulled upward, the paint in the placement trough will be discharged quickly, which will instantly increase the resistance to the upward movement of the placement trough, thereby increasing the resistance of the lifting rod to pull the placement trough upward. When the resistance is too large, the lifting rod may be damaged, posing a certain safety hazard.

[0005] Therefore, a gantry type electrophoretic coating equipment processing lifting device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a lifting device for gantry-type electrophoretic coating equipment in order to solve the above-mentioned problem. The utility model improves the problem that when the workpiece is finished painting and the placement slot is pulled upward, the paint in the placement slot will be discharged quickly, which will instantly increase the resistance of the placement slot to move upward, thereby increasing the resistance of the lifting rod to pull the placement slot upward. When the resistance is too large, the lifting rod may be damaged, posing a certain safety hazard.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a lifting device for gantry-type electrophoretic coating equipment processing, comprising: a gantry and a placement frame, the inner side of the gantry is slidably connected to a sliding plate, the inner wall of the gantry is rotatably connected to a screw rod, the top of the gantry is fixedly connected to a motor, the top of the screw rod passes through the gantry and is fixedly connected to the output shaft of the motor, the inner wall of the sliding plate is threadedly connected to the surface of the screw rod, and a protective mechanism is arranged at the bottom end of the sliding plate; wherein, the protective mechanism comprises two moving blocks slidably connected to the bottom end of the sliding plate, the bottom end of the moving block is fixedly connected to a fixed frame, the inner wall of the fixed frame is slidably connected to a piston plate, the bottom end of the piston plate is fixedly connected to a fixed rod, one side of the fixed frame is fixedly connected to a round tube, and the other side of the fixed frame is provided with a locking assembly.

[0008] Preferably, the locking assembly includes a mounting frame fixedly connected to the other side of the fixing frame, a moving plate is slidably connected to the inner wall of the mounting frame, a locking block is fixedly connected to one side of the moving plate, a locking groove is provided on one side of the fixing rod, and a first spring is fixedly connected between the other side of the moving plate and the inner wall of the mounting frame. When the device is in normal use, the locking block is engaged with the locking groove, which is conducive to fixing the fixing rod and ensuring the stability of the fixing rod in normal use.

[0009] Preferably, the vertical cross section of the locking block is a right triangle, and the shape of the locking groove matches the shape of the locking block. When the fixing rod is subjected to an instant downward pulling force, the inclined surface of the locking block and the inclined surface of the locking groove are effective to ensure that the fixing rod can move downward normally when subjected to an instant downward pulling force.

[0010] Preferably, the top of the piston plate is fixedly connected to a second spring, and the top of the second spring is fixedly connected to the inner top wall of the fixed frame. When the momentary downward pulling force applied to the fixing rod gradually weakens, the second spring facilitates the fixing rod to reset the locking block and reengage the locking groove, making it easier to use the device again and improving the practicality of the device.

[0011] Preferably, a protective frame is fixedly connected to the inner wall of the fixed frame to prevent the piston plate from moving excessively when the fixed rod drives it to move downward, thereby ensuring the stability of the device during operation.

[0012] Preferably, both sides of the placement frame are fixedly connected with fixing blocks, the other side of the fixing block is provided with a card slot, and the bottom end of the fixing rod passes through the fixing frame and is fixedly connected with the card block, which is beneficial to improving the stability of fixing the placement frame.

[0013] Preferably, the card block and the card slot are in a cross shape.

[0014] Preferably, a contact pad is fixedly connected to the top of the protection frame, and the contact pad is a rubber component. When the piston plate contacts the protection frame downward, the contact pad is beneficial to protecting the piston plate.

[0015] The beneficial effects of the utility model are:

[0016] 1. When the workpiece is subjected to electrophoretic coating, the placement frame can be used to drive the workpiece to be lifted or lowered by using a motor, a screw rod and a sliding plate. When the device is in normal use, the fixing rod is fixed by a locking block and a locking groove for clamping, thereby ensuring the stability of the fixing rod in normal use. The fixing frame and the fixing rod are set to be retractable, so that the fixing rod can move within a certain range when subjected to a sudden downward pulling force, which is conducive to dispersing the instantaneous downward pulling force, reducing stress concentration, and effectively protecting the fixing frame and the fixing rod, thereby improving the stability of the fixing frame and the fixing rod pulling the placement frame downward. At the same time, when the fixing rod moves downward, the locking block and the round tube inhale the external gas, thereby preventing the fixing rod from being pulled downward quickly, thereby ensuring the stability of the fixing rod moving downward, thereby increasing the safety of the device during operation;

[0017] 2. When the momentary downward pulling force on the fixing rod gradually weakens, the second spring helps the fixing rod to reset and the locking block to engage with the locking groove again, which makes it easier to use the device again and improves the practicability of the device.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, a lifting device for gantry-type electrophoretic coating equipment processing includes: a gantry 1 and a placement frame 2, the inner side of the gantry 1 is slidably connected to a sliding plate 3, the inner wall of the gantry 1 is rotatably connected to a screw rod 4, the top of the gantry 1 is fixedly connected to a motor 5, the top of the screw rod 4 passes through the gantry 1 and is fixedly connected to the output shaft of the motor 5, the inner wall of the sliding plate 3 is threadedly connected to the surface of the screw rod 4, and a protective mechanism 6 is arranged at the bottom end of the sliding plate 3; wherein the protective mechanism 6 includes two moving blocks 601 slidably connected to the bottom end of the sliding plate 3, the bottom end of the moving block 601 is fixedly connected to a fixed frame 602, the inner wall of the fixed frame 602 is slidably connected to a piston plate 603, the bottom end of the piston plate 603 is fixedly connected to a fixed rod 604, one side of the fixed frame 602 is fixedly connected to a round tube 605, and the other side of the fixed frame 602 is provided with a locking assembly 606.

[0026] When the workpiece is subjected to electrophoretic coating, the workpiece is placed in a placement frame 2 , and a bottom end of the placement frame 2 is provided with through holes distributed in a rectangular array.

[0027] When the sliding plate 3 needs to be moved downward, the motor 5 is started, and the output shaft of the motor 5 drives the screw rod 4 to rotate. When the screw rod 4 rotates, the sliding plate 3 can be moved downward.

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, the locking assembly 606 includes an installation frame 6061 fixedly connected to the other side of the fixed frame 602, the inner wall of the installation frame 6061 is slidably connected with a movable plate 6062, one side of the movable plate 6062 is fixedly connected with a locking block 6063, one side of the fixed rod 604 is provided with a locking groove 6065, and a first spring 6064 is fixedly connected between the other side of the movable plate 6062 and the inner wall of the installation frame 6061.

[0029] When the device is in the initial state, under the action of the first spring 6064, the locking block 6063 enters the locking groove 6065 and engages with the locking groove 6065 to fix the fixing rod 604. The first spring 6064 is a strong spring with a relatively high elastic coefficient and load-bearing capacity, which will give the locking block 6063 a strong resistance. When the first spring 6064 is squeezed with a large force, it will deform.

[0030] The vertical cross section of the locking block 6063 is a right triangle, and the shape of the locking groove 6065 matches the shape of the locking block 6063 .

[0031] When the resistance to the upward movement of the placement frame 2 increases instantaneously, the downward pulling force given to the fixing rod 604 by the placement frame 2 will increase instantaneously, and the instantly increased pulling force will pull the fixing rod 604 downward. At this time, under the action of the inclined surfaces of the locking groove 6065 and the locking block 6063, the downward movement of the fixing rod 604 will squeeze the locking block 6063, causing the locking block 6063 to move to the side away from the locking groove 6065. When the locking block 6063 moves, it will push the movable plate 6062 to move into the installation frame 6061 and squeeze the first spring 6064.

[0032] When the downward pulling force of the fixed rod 604 given by the placement frame 2 increases instantly, the fixed rod 604 moves downward, and under the action of the piston plate 603, the external gas is sucked through the round tube 605. At this time, the resistance to the sudden downward movement of the fixed rod 604 is increased, and the instantaneous downward pulling force of the fixed rod 604 is buffered to prevent the fixed rod 604 from moving downward quickly.

[0033] like Figure 3 and Figure 4 As shown, the top end of the piston plate 603 is fixedly connected to a second spring 607 , and the top end of the second spring 607 is fixedly connected to the inner top wall of the fixed frame 602 .

[0034] When the fixing rod 604 moves downward, the second spring 607 will be pulled up. When the instantaneous downward pulling force applied to the fixing rod 604 gradually weakens, the second spring 607 will drive the piston plate 603 to move upward. When the piston plate 603 moves upward, the gas entering the fixing frame 602 will be discharged through the circular tube 605. At the same time, under the action of the first spring 6064, the locking block 6063 enters the locking groove 6065.

[0035] like Figure 3 and Figure 4 As shown, the inner wall of the fixing frame 602 is fixedly connected with the protection frame 608. The surface of the fixing rod 604 does not contact the inner wall of the protection frame 608, and the level of the bottom end of the protection frame 608 is higher than the level of the top end of the locking block 6063.

[0036] like Figure 5As shown, both sides of the placement frame 2 are fixedly connected with a fixing block 201, and the other side of the fixing block 201 is provided with a card slot 202. The bottom end of the fixing rod 604 passes through the fixing frame 602 and is fixedly connected with a card block 609. The card block 609 and the card slot 202 are in a "cross" shape.

[0037] When the placement frame 2 is installed, the moving block 601 is driven to move, thereby driving the fixed frame 602 and the fixed rod 604 to move, and driving the clamping block 609 to enter the clamping slot 202 .

[0038] Two electric push rods are fixedly connected to the bottom end of the sliding plate 3, and the telescopic ends of the two electric push rods are respectively fixedly connected to one side of the corresponding moving block 601, so that when the moving block 601 moves, the electric push rod is started by the controller, and the telescopic end of the electric push rod can push the moving block 601 to move.

[0039] like Figure 3 and Figure 4 As shown, a contact pad 6081 is fixedly connected to the top of the protection frame 608 , and the contact pad 6081 is a rubber component. The shape of the contact pad 6081 is the same as that of the protection frame 608 .

[0040] When the utility model is in use, when the workpiece is subjected to electrophoretic coating, the workpiece is placed in the placement frame 2, and the moving block 601 is driven to drive the fixed frame 602 and the fixed rod 604 to move, so that the clamping block 609 enters the clamping slot 202, and the placement frame 2 is fixed. The motor 5 is started to drive the screw rod 4 to rotate, and the sliding plate 3 moves downward, so that the placement frame 2 can drive the workpiece into the coating.

[0041] When the workpiece is finished painting and the resistance to pulling the placement frame 2 upward increases instantaneously, the instantly increased pulling force will pull the fixed rod 604 downward. At this time, the fixed rod 604 drives the piston plate 603 to move downward, the second spring 607 is pulled up, and the external gas enters the fixed frame 602 through the circular tube 605. Under the action of the inclined surfaces of the locking groove 6065 and the inclined surfaces of the locking block 6063, the downward movement of the fixed rod 604 will squeeze the locking block 6063, causing the locking block 6063 to move to the side away from the locking groove 6065. When the locking block 6063 moves, it will push the movable plate 6062 to move into the installation frame 6061 and squeeze the first spring 6064. The instantaneous downward pulling force is dispersed by the downward movement of the fixed rod 604.

[0042] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
