[0024] Embodiment
[0025] Such asFigures 1-4 As shown in the figure, a contact welding fixture proposed by the present utility model includes a welding table 1 and contacts, and further includes: an installation groove 11 opened on the welding table 1 for the contacts to be inserted, and a placement plate 2 for placing the contacts is slidably connected inside the installation groove 11; a pair of clamping mechanisms, which are symmetrically arranged on both sides of the sliding groove 3 and are arranged in the installation groove 11 to clamp the contacts after pressing the placement plate 2; a sliding groove 3 opened on the welding table 1 on one side of the clamping mechanism, and a block mechanism for restricting the placement plate 2 from popping up the contacts upward is arranged inside the sliding groove 3.
[0026] Further, the clamping mechanism includes a plurality of telescopic grooves 12 opened in the installation groove 11, a first L-shaped rod 13 is slidably connected inside each telescopic groove 12, a pulling spring 14 is arranged at the proximal end of each pair of first L-shaped rods 13 close to each other, a cross bar 17 is fixedly connected to the top end of the first L-shaped rod 13, a pair of triangular abutting frames 22 for abutting against the cross bar 17 are fixedly connected to the lower surface of the placement plate 2, and a second L-shaped rod 15 for clamping the contacts on the placement plate 2 is fixedly connected to the end of the cross bar 17 away from the triangular abutting frame 22.
[0027] Among them, the block mechanism includes a push button 31 slidably connected in the sliding groove 3, a plurality of stripe protrusions 34 are arranged linearly at the top end of the push button 31, and the function of the stripe protrusions 34 is to increase the friction between the finger and the top end of the push button 31 to prevent the finger from pushing the stripe protrusions 34 to slide. A plug rod 33 is fixedly connected to the bottom end of the push button 31, and a hemispherical block that automatically retracts into the sliding groove 3 after being abutted by the placement plate 2 is arranged at one end of the plug rod 33 close to the placement plate 2. The function of the hemispherical block is to prevent one end of the plug rod 33 from interfering with the clamping when the placement plate 2 moves downward. A pushing spring 32 is fixedly connected to one end of the plug rod 33, and the function of the pushing spring 32 is to keep the hemispherical block of the plug rod 33 in a state of being stuck in the card slot 21 all the time. The end of the pushing spring 32 away from the plug rod 33 is fixedly connected to the inner wall of the sliding groove 3, and a card slot 21 for the plug rod 33 to be inserted is opened on the placement plate 2.
[0028] Furthermore, the block mechanism further includes a pair of limit clamping rods 16 on the inner top of the installation groove 11 for restricting the placement plate 2 from sliding downward, and a reset spring 18 for pushing the placement plate 2 to restore its original position in the installation groove 11 is arranged on the upper surface of the limit clamping rod 16. The function of the reset spring 18 is that when the placement plate 2 is not stuck, the placement plate 2 can be restored to its original position again and reused through the elastic thrust of the reset spring 18.
[0029] In this embodiment, when the contact welding fixture needs to be used, the contact is placed on the upper surface of the placing plate 2 and pressed downwards. At this time, the placing plate 2 drives a pair of triangular abutment frames 22 to move downwards along the installation groove 11 until the bottom of the placing plate 2 abuts against a pair of limit clamping rods 16 in the installation groove 11. At the same time, the first L-shaped rods 13 in the installation grooves 11 on both sides of each triangular abutment frame 22 drive the cross bars 17 to move towards the triangular abutment frames 22 due to the elastic tension of the pulling springs 14. The cross bars 17 drive the second L-shaped rods 15 to move towards the placing plate 2. Since the placing plate 2 moves downwards in the installation groove 11, the end of the second L-shaped rod 15 far from the cross bar 17 clamps the contact on the placing plate 2. Finally, when the placing plate 2 abuts against the limit clamping rod 16 along the installation groove 11 downwards, the bottom of the placing plate 2 will first abut against one end of the insertion rod 33, causing the insertion rod 33 to retract into the sliding groove 3. When the card slot 21 at the bottom of the placing plate 2 coincides with one end of the insertion rod 33, the insertion rod 33 can insert the end with the hemispherical block into the card slot 21 through the elastic thrust of the pushing spring 32 in the sliding groove 3, thereby restricting the upward movement of the placing plate 2, so that a plurality of second L-shaped rods 15 firmly clamp the contact on the placing plate 2. When the welded contact needs to be removed from the placing plate 2, the push button 31 can be slid in the sliding groove 3 in a direction away from the placing plate 2. At this time, one end of the insertion rod 33 is not inserted into the card slot 21 at the bottom of the placing plate 2, and the placing plate 2 will be elastically pushed by the reset spring 18 on the upper surface of the limit clamping rod 16, so that the placing plate 2 returns to its original position for repeated use.
