Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dip coating machine technology, specifically relating to a high-efficiency workpiece clamping device for dip coating machines. Background Technology
[0002] A dip coating machine is a processing device that immerses a workpiece heated to a certain temperature into a dip coating solution, then bakes the dip-coated workpiece in an oven to solidify the solution, and finally removes it from the oven and cools it. A clamping device is needed to move the workpiece before and after dip coating. Existing clamping devices can only clamp one type of workpiece, lacking versatility and unable to clamp different types of workpieces. Clamping different types of workpieces requires changing to fixtures suitable for that type, which is costly, time-consuming, and labor-intensive. Furthermore, current clamping structures can only clamp one workpiece at a time, severely impacting dip coating efficiency. Therefore, improvements are necessary to address these issues. Utility Model Content
[0003] The technical problem solved by this utility model is to provide a high-efficiency workpiece clamping device for a dip coating machine. By optimizing the clamping structure, a lateral adjustment device is set on the fixed frame and connected to multiple movable clamping plates. This device drives the movable clamping plates to move towards or in the opposite direction to the fixed clamping plates at the bottom of the fixed frame. The movable clamping plates cooperate with the fixed clamping plates to clamp and fix the workpiece. Multiple workpieces can be clamped or released at one time, increasing the number of workpieces that can be clamped. This provides conditions for improving the efficiency of workpiece dip coating. The structure is simple, the design is novel, the adjustment is convenient and quick, and the application value is high.
[0004] The technical solution adopted by this utility model is: a high-efficiency workpiece clamping device for a dip coating machine, including a fixed frame fixed on the lifting frame of the dip coating machine. Multiple fixed clamping plates are evenly distributed on the bottom of the fixed frame, and multiple movable clamping plates corresponding to the positions of the fixed clamping plates pass through the guide elongated holes at the bottom of the fixed frame and are fixedly and adjustablely connected to the movable part of the transverse adjustment device located inside the fixed frame. When the transverse adjustment device drives the movable clamping plates to move left and right along the length direction of the guide elongated holes through the movable part, the workpiece located between the movable clamping plates and the fixed clamping plates at the top is clamped or released.
[0005] The transverse adjustment device includes a lead screw and a long threaded sleeve. The two ends of the lead screw are rotatably mounted on the two side walls of the fixed frame, and the long threaded sleeve is adapted to be connected to the lead screw. The upper end of the movable clamp is adjustablely fixed to the long threaded sleeve. One end of the lead screw passes through the fixed frame and is fixedly connected to the handle on its outside. By rotating the lead screw through the handle, the long threaded sleeve moves left and right along the length of the lead screw, and the movable clamp and the fixed clamp clamp clamp or release the workpiece.
[0006] Furthermore, the through hole fitting at the upper end of the movable clamping plate is adapted to the long threaded sleeve. A positioning groove is formed on one side wall of the long threaded sleeve, and the handwheel bolt threaded to the upper end of the movable clamping plate corresponds to and is adapted to the positioning groove. The fixed position of the movable clamping plate on the long threaded sleeve is adjusted by the handwheel bolt.
[0007] Furthermore, a baffle is fixed to the end of the long threaded sleeve.
[0008] Furthermore, the movable clamping plate is an L-shaped plate with a lower end thickness greater than the upper end thickness that protrudes outward toward the fixed clamping plate side.
[0009] Furthermore, a fixing sleeve is provided on the side wall of the fixing frame on the same side as the handle, which is fitted onto the lead screw. When the position of the long screw sleeve is adjusted to the correct position, the lead screw is tightened and fixed by a handwheel bolt threaded to the outer wall of the fixing sleeve.
[0010] Furthermore, the fixing frame includes a U-shaped frame with the slot facing downward and a horizontal plate fixed at the slot of the U-shaped frame. The horizontal adjustment device is located above the horizontal plate and installed in the U-shaped slot of the U-shaped frame. The upper end of the fixing clamp is fixed to the bottom surface of the horizontal plate, and the guide elongated hole is provided on the horizontal plate.
[0011] Advantages of this utility model compared to the prior art:
[0012] 1. This technical solution optimizes the clamping structure by using a transverse adjustment device that connects to multiple movable clamping plates on a fixed frame and drives the movable clamping plates to move toward or in the opposite direction to the corresponding fixed clamping plates at the bottom of the fixed frame. This allows the movable clamping plates to work together with the fixed clamping plates to clamp and fix the workpiece. Multiple workpieces can be clamped or released at once, increasing the number of workpieces that can be clamped and providing conditions for improving the efficiency of workpiece dip coating.
[0013] 2. The upper part of the movable clamping plate in this technical solution adopts an adjustable structure and is installed on the long threaded sleeve, which provides adjustment conditions for clamping and fixing workpieces with different clamping thicknesses. It can not only clamp and fix workpieces of the same type, but also workpieces with different clamping thicknesses, and has good clamping flexibility.
[0014] 3. This technical solution uses a fixed sleeve that is fixedly mounted on the screw rod on one side of the fixed frame and has a handwheel bolt installed radially. When the long screw sleeve moves into place, it locks and fixes the position of the long screw rod, thereby ensuring the position of the moving clamping plate and avoiding the problem of the workpiece falling due to the operator's accidental operation or contact with the handle. This ensures the safety and reliability of the workpiece clamping.
[0015] 4. This technical solution has a simple structure, novel design, and convenient and quick adjustment. It increases the number of workpieces of the same or different types that can be clamped, has strong versatility, and meets the dip coating requirements of different types of workpieces.

[0020] High-efficiency workpiece clamping devices for dip coating machines, such as Figure 1As shown, the device includes a fixed frame 1 fixed to the lifting frame of the dip coating machine. Multiple fixed clamping plates 2 are evenly distributed at the bottom of the fixed frame 1. Multiple movable clamping plates 3, corresponding to the positions of the fixed clamping plates 2, pass through guide holes 4 at the bottom of the fixed frame 1 and are fixedly and adjustablely connected to the movable part of a lateral adjustment device located inside the fixed frame 1. The lateral adjustment device drives the movable clamping plates 3 to move left and right along the length of the guide holes 4 via the movable part, thus clamping or releasing the workpiece located between the movable clamping plates 3 and the fixed clamping plates 2. In this structure, by optimizing the clamping structure and using a lateral adjustment device connected to multiple movable clamping plates 3 on the fixed frame 1, and driving the movable clamping plates 3 to move towards or away from the corresponding fixed clamping plates 2 at the bottom of the fixed frame 1, the movable clamping plates 3 cooperate with the fixed clamping plates 2 to clamp and fix the workpiece. This allows for the clamping or releasing of multiple workpieces at once, increasing the number of workpieces that can be clamped and providing conditions for improving the efficiency of dip coating.
[0021] The specific structure of the transverse adjustment device is as follows: The transverse adjustment device includes a lead screw 5 and a long threaded sleeve 6. The two ends of the lead screw 5 are rotatably mounted on the two side walls of the fixed frame 1, and the long threaded sleeve 6 is adapted to be connected to the lead screw 5. Rotating the lead screw 5 allows the long threaded sleeve 6 to move left and right along the length direction of the lead screw 5. The upper end of the movable clamping plate 3 is adjustablely fixed to the long threaded sleeve 6, so that the movable clamping plate 3 can be adjusted to a fixed position on the long threaded sleeve 6. One end of the lead screw 5 passes through the fixed frame 1 and is fixedly connected to the handle 7 on its outer side. By rotating the lead screw 5 through the handle 7, the long threaded sleeve 6 moves left and right along the length direction of the lead screw 5, and the movable clamping plate 3 and the fixed clamping plate 2 clamp or release the workpiece. Specifically, the through hole at the upper end of the movable clamping plate 3 is fitted onto the long threaded sleeve 6. The long threaded sleeve 6 has a positioning groove 8 on one side wall, and the handwheel bolt 9, which is threaded to the upper end of the movable clamping plate 3, corresponds to and is adapted to the positioning groove 8. The fixed position of the movable clamping plate 3 on the long threaded sleeve 6 is adjusted by the handwheel bolt 9. The positioning groove 8 not only ensures the circumferential orientation of the movable clamping plate 3 when it moves along the length of the long threaded sleeve 6, but also ensures the circumferential orientation of the movable clamping plate 3 when the handwheel bolt 9 is pressed against the positioning groove 8. In the above structure, the upper end of the movable clamping plate 3 is installed on the long threaded sleeve 6 with an adjustable position structure, which provides adjustment conditions for clamping and fixing workpieces with different clamping thicknesses. It can not only achieve clamping and fixing of the same type of workpieces, but also clamping and fixing of workpieces with different clamping thicknesses, and has good clamping flexibility.
[0022] The long threaded sleeve 6 is fixed with a baffle 10 at its end. The baffle 10 can be fixed to the end of the long threaded sleeve 6 with screws. The baffle 10 can prevent the long threaded sleeve 6 from slipping out when adjusting the position of the movable clamping plate 3. Specifically, the movable clamping plate 3 is an L-shaped plate with a lower end thickness greater than the upper end thickness that protrudes outward toward the fixed clamping plate 2. Alternatively, the movable clamping plate 3 can be processed into a flat plate with a uniform thickness as needed.
[0023] The locking structure after the long threaded sleeve 6 is adjusted is as follows: The fixed sleeve 11, which is fitted onto the lead screw 5, is provided on the side wall of the fixed frame 1 on the same side as the handle 7. When the position of the long threaded sleeve 6 is adjusted to the correct position, the lead screw 5 is tightened and fixed by the handwheel bolt 12 threaded to the outer wall of the fixed sleeve 11. With the above structure, after the long threaded sleeve 6 drives multiple movable clamping plates 3 to clamp and fix the workpiece on the corresponding fixed clamping plate 2, the reliability of the position of the long threaded sleeve 6 is ensured, thereby ensuring the position of the movable clamping plate 3. This avoids the problem of the workpiece being loosened and falling due to the operator's accidental operation or contact with the handle 7, and ensures the safety and reliability of the workpiece clamping.
[0024] The specific structure of the fixing frame 1 is as follows: The fixing frame 1 includes a U-shaped frame 1-1 with the slot facing downward and a horizontal plate 1-2 fixed at the slot position of the U-shaped frame 1-1. The horizontal adjustment device is located above the horizontal plate 1-2 and installed in the U-shaped slot of the U-shaped frame 1-1. The upper end of the fixing clamp 2 is fixed to the bottom surface of the horizontal plate 1-2, and the guide elongated hole 4 is provided on the horizontal plate 1-2.
[0025] This technical solution has a simple structure, novel design, and convenient and quick adjustment. It increases the number of workpieces of the same or different types that can be clamped, has strong versatility, and meets the dip coating requirements of different types of workpieces.
