[0020] Embodiment 1:

[0021] A dipping plastic rapid positioning and clamping device, as Figure 1 shown, includes a base 1 and a clamping assembly 2. The number of clamping assemblies 2 is multiple groups and they are arranged at intervals. Each clamping assembly 2 is provided with a plurality of loose joint bolts 3 penetrating through the base 1. Between two adjacent loose joint bolts 3, there is a clamping seat 4 for fixing the workpiece to be dipped in plastic. In order to make the dipping positions of the workpieces to be dipped in plastic uniform and neat and beautiful after dipping, all the clamping seats 4 and the loose joint bolts 3 are connected into a whole through a first positioning rod 5. A fastening nut is provided on the back of the loose joint bolt 3. By adjusting the meshing position of the loose joint bolt 3 and the fastening nut, the bottom surface of the clamping seat 4 is always in contact with the base 1, and the heights of the clamping seats 4 are unified. By adjusting the meshing position of the loose joint bolt 3 and the fastening nut, the device can also be applicable to clamping seats 4 with different height dimensions.

[0022] As Figure 3 shown, in this embodiment, the clamping seat 4 includes a fixed joint 6 and a locking joint 7. The middle part of the fixed joint 6 is provided with an external thread 8. The upper part of the external thread 8 is provided with a clamping head 9, and the lower part of the external thread 8 is provided with a limit seat 10. The clamping head 9 is provided with a plurality of expansion grooves 12, and the expansion grooves 12 divide the clamping head 9 into a plurality of clamping pieces 13. In order to prevent the workpiece to be dipped in plastic from falling off during the dipping process, the locking joint 7 is sleeved outside the clamping head 9, and its inner cavity is provided with a tapered hole and an internal thread 11 matching with the external thread 8. When the workpiece to be dipped in plastic has a cylindrical structure, the cylindrical structure of the workpiece to be dipped in plastic is directly inserted into the clamping head 9, and the clamping pieces 13 generate a small amount of elastic deformation to hold the workpiece to be dipped in plastic tightly. The locking joint 7 is tightened through a thread pair, and the tapered hole of the locking joint 7 further tightens the clamping pieces 13 to prevent loosening. When the locking joint 7 is loosened, the workpiece to be dipped in plastic can be smoothly pulled out, which is convenient for loading and unloading.

[0023] The limit seat 10 is provided with a through hole 14, and the diameter of the through hole 14 is equal to the diameter of the hole 15 of the loose joint bolt 3. The first positioning rod 5 penetrates through the through hole 14 and the hole 15 to connect the clamping seat 4 and the loose joint bolt 3. The first positioning rod 5 is a smooth round rod.

[0024] In order to facilitate the manual tightening and loosening of the locking joint 7, a plurality of anti-slip grooves 16 are provided on the outside of both the limit seat 10 and the locking joint 7.

[0025] Embodiment 2:

[0026] The difference from Embodiment 1 is that in this embodiment, asFigure 2 and Figure 4 As shown, in order to fix workpieces to be dip-molded of different types, when the workpiece to be dip-molded is in a sheet structure, the clamping seat 4 is in the form of a clip, including a clamping body 17 and clamping plates 18 symmetrically arranged on both sides of the clamping body 17. A clamping area 19 is provided between the two groups of clamping plates 18. A limiting area 20 for the first positioning rod 5 to pass through is provided in the clamping body 17. The first positioning rod 5 can pass through the limiting area 20 and the hole 15 of the loose bolt 3 to connect the clamping seat 4 with the loose bolt 3, so that the dipping liquid height of the workpiece to be dip-molded is the same after dipping. The workpiece to be dip-molded is inserted into the clamping area 19, and the two groups of clamping plates 18 can hold the workpiece to be dip-molded tightly to avoid loosening, realizing the quick loading and unloading of the workpiece to be dip-molded. In order to prevent the clamping seat 4 from tilting, a second positioning rod 21 passes through all the clamping assemblies 2. The second positioning rod 21 is located between the clamping body 17 and the base 1. By adjusting the meshing position of the loose bolt 3 and the fastening nut, the position of the second positioning rod 21 is fixed. By adjusting the meshing position of the loose bolt 3 and the fastening nut, the device can also be applied to clamping seats 4 of different height dimensions.

[0027] The working principle of this device is as follows: all the loose bolts 3 are installed on the base 1, and fastening nuts are screwed on the backs of the loose bolts 3. Clamping seats 4 are provided between every two loose bolts 3, and the loose bolts 3 and the clamping seats 4 are penetrated by the first positioning rods 5. By adjusting the meshing position of the fastening nuts, the clamping seats 4 are at the same height. The workpiece to be dip-molded is connected to the clamping seat 4, and the device is suspended on the dip-molding sling, and then the dip-molding operation can be carried out. This device can keep all the workpieces to be dip-molded at the same height position all the time, so as to ensure that after the dip-molding operation, the dipping liquid positions of the workpieces to be dip-molded of the same model are unified, neat and beautiful, meeting the higher process requirements of the dip-molding operation. And this device can meet the dip-molding requirements of different types of workpieces to be dip-molded only by replacing the clamping seat 4, with a wider application range and stronger versatility.

[0028] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
