Detailed Implementation
[0024] The present invention will now be described in conjunction with specific embodiments.
[0025] Example 1, as Figures 1 to 3 As shown, a novel quick-clamping welding fixture includes a fixture base 1, on which two quick clamps 2 are arranged facing each other and spaced apart. Each quick clamp 2 has a clamp arm 21 with a pressure rod 3.
[0026] Among them, such as Figures 1 to 3 As shown, a replaceable mold core 4 is installed between two quick clamps 2 on the fixture base 1. The upper surface of the replaceable mold core 4 is provided with a product placement area, which includes a first product placement position 41 and a second product placement position 42. The upper surface of the positioning mold core is provided with a plurality of first positioning protrusions 43 arranged at intervals and protruding upwards on the side of the first product placement position 41. The upper surface of the positioning mold core is provided with a plurality of second positioning protrusions 44 arranged at intervals and protruding upwards on the side of the second product placement position 42.
[0027] Furthermore, such as Figures 1 to 3 As shown, each quick clamp 2 has a vertically penetrating elongated hole 211 in its clamping arm 21, and each pressure rod 3 has a vertically arranged screw part 31. The screw part 31 of each pressure rod 3 passes vertically through the elongated hole 211 of the corresponding quick clamp 2's clamping arm 21. Each pressure rod 3's screw part 31 is screwed with an upper locking nut 32 and a lower locking nut 33. The upper locking nut 32 is located on the upper end side of the corresponding quick clamp 2's clamping arm 21, and the lower locking nut 33 is located on the lower end side of the corresponding quick clamp 2's clamping arm 21.
[0028] When using the novel quick-clamping welding fixture of this embodiment to assist in the welding of the first hardware product 61 and the second hardware product 62, the operation steps include:
[0029] Step a: The first hardware product 61 is placed in the first product placement position 41 of the replaceable mold core 4, and the second hardware product 62 is placed in the second product placement position 42 of the replaceable mold core 4. The first hardware product 61 is side-positioned by a number of first positioning protrusions 43, and the second hardware product 62 is side-positioned by a number of second positioning protrusions 44. In this embodiment, the first positioning protrusions 43 and the second positioning protrusions 44 can ensure that the first hardware product 61 and the second hardware product 62 are accurately placed in the corresponding first product placement position 41 and second product placement position 42.
[0030] Step b: After the first hardware product 61 and the second hardware product 62 are positioned on the replaceable mold core 4, operate each quick clamp 2 and adjust each quick clamp 2 to the clamping state. The clamping arm 21 of one quick clamp 2 presses down on the first hardware product 61 through the corresponding pressure rod 3 and presses the first hardware product 61 to be pressed and fixed. The clamping arm 21 of the other quick clamp 2 presses down on the second hardware product 62 through the corresponding pressure rod 3 and presses the second hardware product 62 to be pressed and fixed.
[0031] Step c: After the first hardware product 61 and the second hardware product 62 are pressed and fixed, they can be welded by welding equipment to complete the welding process of the first hardware product 61 and the second hardware product 62.
[0032] Step d: After the first hardware product 61 and the second hardware product 62 have completed the welding process, operate each quick clamp 2 and adjust each quick clamp 2 to the loose state. Then, remove the welded first hardware product 61 and the second hardware product 62 from the replaceable mold core 4.
[0033] It should be emphasized that the replaceable mold core 4 in this embodiment adopts a replaceable structure design. For different hardware product welding processes, the staff only needs to replace the replaceable mold core 4 that is suitable for it. This allows for quick adjustment according to different hardware product welding processes. It has strong versatility and does not require replacing the entire fixture, which can effectively reduce the fixture manufacturing cost.
[0034] It should be further noted that each pressure rod 3 is locked and fixed to the clamping arm 21 of the corresponding quick clamp 2 by the upper locking nut 32 and the lower locking nut 33 respectively. In use, the operator can adaptably adjust the lateral position of the pressure rod 3 along the elongated hole 211 according to the needs of the clamping and fixing position of the hardware product. The clamping height of the pressure rod 3 can be adjusted by adjusting the vertical position of the upper locking nut 32 and the lower locking nut 33 relative to the screw part 31. The above-mentioned adjustable structure design of the pressure rod 3 can effectively improve the versatility of the fixture.
[0035] In summary, the novel quick-clamping welding fixture of this embodiment has the advantages of novel structural design and strong versatility through the above structural design. It can also be quickly adjusted according to the welding processing of different hardware products to reduce the manufacturing cost of the fixture.
[0036] Example 2, as Figures 1 to 3 As shown, the difference between this embodiment 2 and embodiment 1 is that the lower end of the screw part 31 of each pressure rod 3 is respectively equipped with a urethane pressure block 34.
[0037] When the pressure rod 3 is pressed down to fix the corresponding hardware product, the pressure rod 3 contacts and presses against the surface of the hardware product through the urethane pressure block 34 to avoid the hardware product being crushed.
[0038] Example 3, as Figures 1 to 3 As shown, the difference between this embodiment 3 and embodiment 1 is that the first positioning protrusion 43, the second positioning protrusion 44 and the replaceable mold core 4 are integrated into one structure.
[0039] Example 4, as Figure 2 and Figure 3 As shown, the difference between this embodiment 4 and embodiment 1 is that: the replaceable mold core 4 is equipped with a first positioning pin 51 at the first product placement position 41, and the replaceable mold core 4 is equipped with a second positioning pin 52 at the second product placement position 42. The first positioning pin 51 and the second positioning pin 52 protrude from the upper surface of the replaceable mold core 4 respectively.
[0040] When the first hardware product 61 is positioned in the first product placement position 41 of the replaceable mold core 4, the first positioning pin 51 is inserted into the structural hole of the first hardware product 61. That is, by cooperating with the structural hole of the first hardware product 61 through the first positioning pin 51, this embodiment 4 can realize the rapid positioning and placement of the first hardware product 61.
[0041] Similarly, when the second hardware product 62 is positioned in the second product placement position 42 of the replaceable mold core 4, the second positioning pin 52 is inserted into the structural hole of the second hardware product 62. That is, by cooperating with the structural hole of the second hardware product 62 through the second positioning pin 52, this embodiment 4 can realize the rapid positioning and placement of the second hardware product 62.
[0042] Example 5 differs from Example 1 in that: the upper surface of the fixture base 1 is equipped with a number of spaced positioning pins (not shown in the figure) corresponding to the replaceable mold core 4, and the replaceable mold core 4 is provided with positioning pin holes (not shown in the figure) for each positioning pin, and each positioning pin is inserted into the corresponding positioning pin hole.
[0043] When the replaceable mold core 4 is installed on the fixture base 1, each positioning pin of the fixture base 1 is inserted into the corresponding positioning pin hole of the replaceable mold core 4 to achieve quick positioning and placement of the replaceable mold core 4.
[0044] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
