Description

Technical Field

[0001] The utility model relates to the technical field of welding jigs, in particular to a welding jig locking clamp. Background Art

[0002] A fixture is a large category of tools used in carpentry, ironwork, fitter, machinery, electronic control and some other handicrafts. It is mainly used as a tool to assist in controlling position or movement (or both). Fixtures can be divided into three categories: process assembly fixtures, project testing fixtures and circuit board testing fixtures. In the process of welding hardware, it is generally necessary to clamp and fix the hardware with the clips on the fixture.

[0003] Most of the existing welding jig locking clamps use spring pressure clamps. For some larger products that need to be welded, the clamping force of the spring pressure clamp is not enough, and the product cannot be fixed well. It is not firm enough and is prone to displacement during the welding process of the product. At the same time, after welding, the existing clamps require many operation steps to remove the product from the clamp, which affects work efficiency. Therefore, it is necessary to design a welding jig locking clamp to solve the above problems. Utility Model Content

[0004] The utility model proposes a welding jig locking clamp, which aims to solve the problem that the existing clamps in the prior art use spring pressure clamps, and the clamping force is insufficient for some larger products that need to be welded. After the welding is completed, many operation steps are required to remove the product from the clamp, which affects the work efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The top end of the screw rod is provided with a connecting rod, and the bottom end of the screw rod is provided with a connecting rod, and the connecting rod has a contact plate, and the contact plate has a contact plate, and the contact plate has a contact plate.

[0007] Preferably, the spring abuts against the baffle plate and the push plate respectively.

[0008] Preferably, when the lower surface of the limit block contacts the upper surface of the inverted L-shaped vertical frame, the distance between the pressing plate and the workbench is 1 cm.

[0009] Preferably, the lower surface of the pressing plate is a rough surface.

[0010] Preferably, a bearing embedded in the connecting block is sleeved on the lower end of the screw rod. A limit ring is fixedly connected above the bearing at the lower end of the screw rod, and the bottom end of the screw rod abuts against the support seat.

[0011] Preferably, the screw rod is threadedly connected to the upper horizontal plate of the inverted L-shaped vertical frame.

[0012] The beneficial effects of the present utility model are as follows: When in use, first pull the handle outwards, pull the push plate to one side of the baffle, place the product to be welded on the workbench, release the handle, and under the action of the spring reset, push the product towards the U-shaped baffle for preliminary fixation. Then, rotate the annular knob to drive the screw rod to rotate, drive the pressing plate to move downwards, perform secondary fixation on the product, increase the clamping force on the product, and prevent it from shifting during the welding process. After the welding is completed, rotate the annular knob to drive the screw rod to rotate, drive the pressing plate to move upwards, then pull the handle outwards, and take out the product.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] Refer to Figure 1-4 , a welding fixture locking clamp, comprising a horizontally arranged workbench 1 and a clamping device mounted on the workbench 1. On the upper surface of the workbench 1, there are a baffle 11 and a U-shaped baffle 12. The baffle 11 and the U-shaped baffle 12 are respectively located on the front and rear sides of the upper surface of the workbench 1. There are two connecting rods 14 penetrating through the baffle 11 on the baffle 11. A handle 13 is arranged on the two connecting rods 14. A push plate 16 is arranged at the other ends of the two connecting rods 14. Springs 15 are sleeved on one side of the two connecting rods 14 close to the push plate 16. On the upper surface of the workbench 1 close to the U-shaped baffle 12, there is an inverted L-shaped vertical frame 17. A clamping device is arranged on the horizontal plate at the upper end of the inverted L-shaped vertical frame 17. The clamping device includes an annular knob 3, a screw rod 32 vertically penetrating through the inverted L-shaped vertical frame 17, and a pressing plate 2. A limit block 31 is arranged on one side of the screw rod 32 close to the annular knob 3. A connecting block 21 is arranged at the lower end of the screw rod 32. Positioning rings 22 are arranged at the bottom ends of the two side walls of the connecting block 21. A pressing plate 2 is arranged on the lower surface of the connecting block 21. The pressing plate 2 is installed on the connecting block 21 through bolts 23.

[0020] When in use, first pull the handle 13 outwards, pull the push plate 16 to one side of the baffle 11, place the product to be welded on the workbench 1, release the handle 13, and under the action of the spring 15 resetting, push the product towards the U-shaped baffle 12 for preliminary fixation. Then rotate the annular knob 3 to drive the screw rod 32 to rotate, drive the pressing plate 2 to move downwards, perform secondary fixation on the product, increase the clamping force on the product, and prevent it from shifting during the welding process. After the welding is completed, rotate the annular knob 3 to drive the screw rod 32 to rotate, drive the pressing plate 2 to move upwards, then pull the handle 13 outwards, take out the product, and different pressing plates 2 can also be replaced according to different products.

[0021] The springs 15 are respectively in mutual contact with the baffle 11 and the push plate 16. When the handle 13 is released, under the action of the springs 15, the product is pushed towards one side of the U-shaped baffle 12 for preliminary fixation.

[0022] When the lower surface of the limit block 31 contacts the upper surface of the inverted L-shaped vertical frame 17, the distance between the pressing plate 2 and the workbench 1 is 1 cm. When rotating the annular knob 3 to move the pressing plate 2 downwards, it prevents the pressing plate 2 from contacting the workbench 1.

[0023] The lower surface of the pressing plate 2 is a rough surface, which improves the friction between the pressing plate 2 and the product when the pressing plate 2 clamps downwards, and prevents the product from shifting and rotating during the welding process.

[0024] The lower end of the screw rod 32 is sleeved with a bearing embedded in the connecting block 21, and a limiting ring 25 is fixedly connected to the lower end of the screw rod 32 and above the bearing. The bottom end of the screw rod 32 abuts against the supporting seat 24. When the annular knob 3 is rotated to drive the screw rod 32 to rotate, the limiting ring 25 can drive the connecting block 21 to rise.

[0025] The screw rod 32 is threadedly connected to the upper end horizontal plate of the inverted L-shaped frame 17 .

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
