Description

Technical Field

[0001] The present application relates to the technical field of welding equipment, and in particular to a welding equipment for a hand mold base used in the production of infiltration products. Background Art

[0002] At present, the hand molds for the production of PVC nitrile latex dipped gloves are all made of stainless steel. The hand mold is a hollow structure of metal sheet as a whole, with a wall thickness of 0.3-2.0 mm and a continuous streamline shape.

[0003] The hand mold includes a palm, a wrist tube and a base in sequence. The wrist tube is a columnar hollow structure with openings at both ends. The palm is welded and fixed to one end of the wrist tube, and the base is inserted into the other end of the wrist tube and welded and fixed. Except for a positioning port on the base, the other parts of the hand mold are sealed to prevent liquid leakage and air permeability. The positioning port at the bottom of the base facilitates the hand mold to be fixed on the positioning seat of the production line.

[0004] With respect to the above-mentioned related technologies, the inventor believes that in the welding process of the above-mentioned base and wrist tube, it is necessary to first align the wrist tube and the base, and then embed the base into the opening of the wrist tube by applying a certain pressure, and then weld the connection between the wrist tube and the base separately. The welding work of the above-mentioned base and wrist tube is all done manually, resulting in low welding efficiency, so there is room for certain improvements. Utility Model Content

[0033] The following is combined with Figure 1-7 This application is described in further detail.

[0034] A welding device for hand mold base used in the production of wet products, referring to Figure 1 and Figure 2 As shown, it includes a frame 1, a left bracket 2 arranged on the frame 1, and a right bracket 3 arranged on the frame 1, a left rotating shaft 4 is rotatably mounted on the left bracket 2, a right rotating shaft 5 is rotatably mounted on the right bracket 3, the left rotating shaft 4 and the right rotating shaft 5 are located at the same horizontal height, the axial directions of the left rotating shaft 4 and the right rotating shaft 5 are aligned, and a synchronous driving mechanism 6 for driving the left rotating shaft 4 and the right rotating shaft 5 to rotate synchronously is arranged on the frame 1.

[0035] The synchronous drive mechanism 6 includes a synchronous drive motor 61 and a synchronous shaft 62. The synchronous shaft 62 is rotatably mounted on the frame 1. The synchronous drive motor 61 is fixed on the frame 1 and connected to the synchronous shaft 62. That is, a first sprocket is coaxially mounted on the synchronous shaft 62, and a second sprocket is mounted on the output shaft of the synchronous drive motor 61. The first sprocket and the second sprocket are connected by a chain.

[0036] The left rotating shaft 4 is connected to the synchronous shaft 62 through the first synchronous belt assembly 63, and the right rotating shaft 5 is connected to the synchronous shaft 62 through the second synchronous belt assembly 64. The first synchronous belt assembly 63 and the second synchronous belt assembly 64 have the same structure, and this embodiment is described by taking the first synchronous belt assembly 63 as an example. The first synchronous belt assembly 63 includes a first synchronous belt pulley, a second synchronous belt pulley and a synchronous belt body, the first synchronous belt pulley is coaxially mounted on the left rotating shaft 4, the second synchronous belt pulley is coaxially mounted on the synchronous shaft 62, and the first synchronous belt pulley and the second synchronous belt pulley are connected by the synchronous belt body. Therefore, the synchronous drive motor 61 drives the synchronous shaft 62 to rotate, and the synchronous shaft 62 can drive the left rotating shaft 4 and the right rotating shaft 5 to rotate synchronously through the first synchronous belt assembly 63 and the second synchronous belt assembly 64.

[0037] Reference Figure 3 As shown, an assembly cylinder 7 is provided at the end of the left rotating shaft 4, and a hand model positioning fixture 8 is installed on the output rod of the assembly cylinder 7, that is, a mounting plate 9 is fixedly provided at the end of the left rotating shaft 4, and the center of the mounting plate 9 is located on the axial direction line of the left rotating shaft 4. The cylinder body of the assembly cylinder 7 is fixed on the mounting plate 9, and a mounting plate 10 is provided on the output rod of the assembly cylinder 7. The hand model positioning fixture 8 is fixed on the mounting plate 10. The hand model positioning fixture 8 is used for installing the hand model in a horizontal direction. The hand model installed on the hand model positioning fixture 8 is not installed with a base, and the hand model is welded by the palm and the wrist tube.

[0038] A number of hand model positioning holes 11 are spaced apart on the hand model positioning jig 8, and the hand model positioning holes 11 are used for inserting the fingers of the hand model. The center of the hand model positioning jig 8 is located on the axial direction line of the left rotating shaft 4. When the hand model is inserted and fixed in the hand model positioning jig 8, the axial direction of the hand model is the same as the axial direction of the left rotating shaft 4. Thus, the left rotating shaft 4 can drive the hand model to rotate coaxially.

[0039] Reference Figure 5 and Figure 6 As shown, a base positioning fixture 12 is provided at the end of the right rotating shaft 5. The base positioning fixture 12 and the hand model positioning fixture 8 are arranged opposite to each other. The base positioning fixture 12 is used for the installation of the base. The base positioning fixture 12 includes a positioning plate 121 fixed on the right rotating shaft 5, and a positioning sleeve 122 fixed on the positioning plate 121. Two positioning blocks 123 are arranged at intervals at the end of the positioning sleeve 122. The two positioning blocks 123 are used to be embedded in the positioning opening of the base, and the base fits on the end of the positioning sleeve 122.

[0040] Among them, an assembly groove is formed between the two positioning blocks 123, and two locking blocks 124 are rotatably installed on the positioning sleeve 122. The two locking blocks 124 are accommodated in the assembly groove, and a telescopic driving mechanism 13 is provided on the right rotating shaft 5 for driving the two locking blocks 124 to rotate to tighten or loosen the base on the end of the positioning sleeve 122.

[0041] Reference Figure 6 and Figure 7 As shown, the telescopic drive mechanism 13 includes a rotary cylinder 131, a pull rod 132 and a connecting rod 133. The rotary cylinder 131 is fixed to the end of the right rotating shaft 5. The right rotating shaft 5 is provided with an assembly cavity 134 along its axial direction. The positioning sleeve 122 is provided with an installation cavity 135. The pull rod 132 is arranged in the assembly cavity 134 of the right rotating shaft 5.

The connecting rod 133 is located in the installation cavity 135 and is sleeved and fixed on the other end of the pull rod 132. One end of the locking block 124 is hingedly mounted on the positioning sleeve 122. The other end of the locking block 124 is hingedly mounted on the end of the connecting rod 133. The hinge groove where the locking block 124 is hinged to the connecting rod 133 is arranged in a long strip shape to provide the locking block 124 with a movable space during the rotation process.

[0042] Therefore, when the base is fitted on the end of the positioning sleeve 122, the rotary cylinder 131 is used to provide the telescopic force for the pull rod 132 to move forward and backward. The pull rod 132 drives the connecting rod 133 to move, and the connecting rod 133 can drive the locking block 124 to rotate, so that the end of the locking block 124 can be pressed against the surface of the base, or the end of the locking block 124 is detached from the surface of the base, which is convenient for the base to be taken away from the positioning sleeve 122.

[0043] The structure of the rotary cylinder 131 belongs to the prior art and will not be elaborated in detail in this embodiment. The rotary cylinder 131 is fixed on the right rotating shaft 5, and the front shell of the rotary cylinder 131 can rotate along with the right rotating shaft 5, but the rotary cylinder 131 does not rotate to drive the pull rod 132 to extend and retract forward and backward.

[0045] The first rotating part 15 includes a supporting disk 151 fixed on the supporting plate 14. The supporting disk 151 is arranged around the base positioning fixture 12. A plurality of first rotating wheels 152 are circumferentially arranged on the disk surface of the supporting disk 151. The first rotating wheels 152 are in contact with the surface of the base, so that the first rotating wheels 152 can not only provide support force for the base but also facilitate the rotation of the base.

[0046] The second rotating part 16 includes a support frame 161 fixed on the support plate 14. The support frame 161 is provided with an arc groove 162 for accommodating the wrist tube of the hand model. The second rotating wheels 163 are rotatably mounted on the notches on both sides of the arc groove 162. The second rotating wheels 163 are in contact with the side walls of the wrist tube of the hand model.

[0047] Reference Figure 4 As shown, a support frame 17 is provided on the frame 1, a support cylinder 18 is provided on the support frame 17, a support plate 19 is installed on the output rod of the support cylinder 18, and an arc-shaped support groove 20 for supporting the side wall of the wrist tube of the hand model is provided on the support plate 19.

The welding gun 22 is located at one side of the base positioning fixture 12 , and the muzzle of the welding gun 22 is aligned with the base edge of the base positioning fixture 12 .

[0049] Thus, by installing the hand model (without the base installed) on the hand model installation jig, and the base installed on the base installation jig, the assembly cylinder 7 is used to drive the hand model positioning jig 8 to move toward the side of the base positioning jig 12, and the base on the base positioning jig 12 will be embedded in the opening of the hand model wrist barrel, and the second rotating part 16 will contact the side wall of the hand model wrist barrel;

[0050] The supporting cylinder 18 drives the supporting plate 19 to move upward, and the arc-shaped supporting groove 20 supports the side wall of the hand model wrist tube, and the hand model and the base are driven to rotate through the synchronous driving mechanism 6, and the welding gun 22 is aimed at the edge of the base to weld the base to the hand model wrist tube.

[0051] The present application solves the problem of manually assembling the base on the hand mold and welding it through welding equipment, thereby improving the efficiency of welding.
