Description

TECHNICAL FIELD

[0001] The utility model belongs to welding tool technical field, concretely relates to a high reliability welding tool. BACKGROUND

[0002] Welding, also known as soldering, is a manufacturing process and technique that joins metals or other thermoplastic materials such as plastics by heating, high temperature, or high pressure.

[0003] There are many energy sources for modern welding, including gas flame, electric arc, laser, electron beam, friction, and ultrasonic wave, etc. Welding can be dangerous to operators, so appropriate protective measures must be taken when welding. The injuries that welding can cause to human body include burn, electric shock, vision impairment, inhalation of toxic gas, and excessive ultraviolet radiation, etc.

[0004] When welding workpiece products, welding tool needs to be used, and the existing welding tool has poor stability when being used, and the welding clamping plate is prone to shaking when moving, so that the workpiece is deviated when the clamping plate shakes slightly, and the welding precision is reduced after welding. To solve the above problems, we provide a high reliability welding tool. UTILITY MODEL CONTENTS

[0005] The utility model discloses a high reliability welding tool, and solves the problems of poor stability of the existing welding tool when being used, the phenomenon that the welding clamping plate is prone to shaking when moving, the workpiece is deviated when the clamping plate shakes slightly, and the welding precision is reduced after welding.

[0006] To achieve the above object, the utility model provides the following technical scheme: a high reliability welding tool, including support seat, four corner positions of support seat are all screw -threaded and are installed with bolt, the upper surface of support seat is fixedly installed with support and branch, the support is screw -threaded and is installed with threaded rod, one end of threaded rod is fixedly installed with hand wheel, the left and right sides of support are all fixedly installed with fixed block, two fixed blocks are rotatably installed with pivot no.

[0007] The above solution utilizes a threaded rod in conjunction with a pressure plate and a rotating arm. The rotation of the threaded rod drives the pressure plate downwards, which in turn drives the bottom of the rotating arm to swing outwards. This, in turn, works with the second rotating shaft to drive the top of the rotating arm to swing the jaws inwards, thus achieving workpiece clamping and fixing. The overall structure is simple, less prone to loosening, and the overall clamping reliability is greatly improved, ensuring the accuracy of subsequent welding operations. By using spring one in conjunction with the pressure plate and spring two in conjunction with the rotating arm, both springs provide a quick reset effect, allowing the pressure plate and rotating arm to quickly reset after the threaded rod rotates and resets, improving the ease of unlocking operations.

[0008] In a preferred embodiment, an anti-slip pad is attached to the lower surface of the support base, and the anti-slip pad has a through hole for the bolt to pass through.

[0009] By adopting the above solution, the direct contact between the support base and the mounting surface can be avoided by setting anti-slip rubber pads. Under the premise that the bolts are screwed into the mounting surface for installation and fixation, the tightening force of the bolts is prevented from causing squeezing damage to the support base and the contact area of ​​the mounting surface, thus achieving a certain protective effect.

[0010] In a preferred embodiment, guide blocks are rotatably mounted on the left and right sides of the support and the left and right sides of the pressure plate, and a spring is fixedly installed between the two guide blocks on the same side.

[0011] Using the above solution, the guide block is used in conjunction with spring one. When the threaded rod rotates and squeezes the pressure plate, causing the pressure plate to rotate downward, spring one will deform and limit the movement. Then, when the threaded rod rotates to reset, the elastic force of spring one is used to quickly pull the pressure plate to reset, improving the ease of operation and use.

[0012] In a preferred embodiment, the spring is provided with a telescopic rod inside, and the two ends of the telescopic rod are fixedly connected to two guide blocks at the same side.

[0013] By adopting the above scheme, the telescopic rod can be used to connect and support the two guide blocks on the same side, thereby supporting and guiding the movement of the pressure plate, improving the stability of the movement, and avoiding swaying.

[0014] In a preferred embodiment, a second spring is fixedly installed on the side of the rotating arm, and the end of the second spring away from the rotating arm is fixedly installed on the inner wall of the support.

[0015] By using the above scheme, the elastic force of spring two is used in conjunction with the rotation of the two rotating arms. When the two rotating arms rotate relative to each other, spring two deforms, thus using the elastic force of spring two to achieve a quick reset effect and improve the ease of operation.

[0016] In a preferred embodiment, the gripper is fitted with a rubber sleeve, which is attached to the outer surface of the gripper.

[0017] By adopting the above solution, the rubber sleeve can protect the surface of the workpiece and prevent damage to the workpiece surface during compression and fixing.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This high-reliability welding fixture uses a threaded rod in conjunction with a pressure plate and a rotating arm. The rotation of the threaded rod drives the pressure plate to rotate downwards, which in turn drives the bottom of the rotating arm to swing outwards. This, in conjunction with the rotating shaft, drives the top of the rotating arm to swing the jaws inwards, thereby clamping and fixing the workpiece. The overall structure is simple and not prone to loosening, greatly improving the overall clamping reliability and ensuring the accuracy of subsequent welding operations.

[0020] This high-reliability welding fixture uses a spring 1 in conjunction with a pressure plate and a spring 2 in conjunction with a rotating arm. Both spring 1 and spring 2 provide a quick reset effect, allowing the pressure plate and rotating arm to quickly reset after the threaded rod rotates and resets, thus improving the ease of unlocking the product.

Detailed Implementation

[0026] Please see Figures 1-4This utility model provides a high-reliability welding fixture, including a support base 1, with bolts 2 threaded at each of the four corners of the support base 1. A support 3 and a support body 4 are fixedly installed on the upper surface of the support base 1. A threaded rod 5 is threaded on the support 3, and a hand crank 6 is fixedly installed at one end of the threaded rod 5. Fixing blocks 7 are fixedly installed on the left and right sides of the support 3. A rotating shaft 8 is rotatably installed between the two fixing blocks 7. A pressure plate 9 is fixedly installed on the outer surface of the rotating shaft 8. The other end of the threaded rod 5 is used in conjunction with the top end of the pressure plate 9. An opening 10 is opened on the front of the support body 4. The bottom end of the pressure plate 9 extends into the interior of the support body 4 through the opening 10. Two openings 11 are opened on the upper surface of the support body 4. A rotating shaft 12 is rotatably installed on the support body 4 opposite to the opening 11. A rotating arm 13 is fixedly installed on the outer surface of the rotating shaft 12. The bottom end of the rotating arm 13 is used in conjunction with the bottom end of the pressure plate 9. A claw 14 is fixedly installed at the top end of the rotating arm 13. The two claws 14 are arranged opposite each other.

[0027] By using a threaded rod 5 in conjunction with a pressure plate 9 and a rotating arm 13, the rotation of the threaded rod 5 drives the pressure plate 9 to rotate downwards, which in turn drives the bottom end of the rotating arm 13 to swing outwards. This, in conjunction with the second rotating shaft 12, drives the top end of the rotating arm 13 to swing the jaws 14 inwards, thereby achieving the clamping and fixing of the workpiece. The overall structure is simple and not prone to loosening, greatly improving the overall clamping reliability and ensuring the accuracy of subsequent welding operations. By using a first spring 17 in conjunction with the pressure plate 9 and a second spring 19 in conjunction with the rotating arm 13, both springs 17 and 19 provide a quick reset effect, allowing the pressure plate 9 and the rotating arm 13 to quickly rotate and reset after the threaded rod 5 rotates and resets, improving the ease of unlocking operations.

[0028] An anti-slip pad 15 is attached to the lower surface of the support base 1. The anti-slip pad 15 has a through hole for the bolt 2 to pass through. By setting the anti-slip pad 15, direct contact between the support base 1 and the mounting surface can be avoided. Under the premise that the bolt 2 is screwed into the mounting surface for installation and fixation, the tightening force of the bolt 2 is prevented from causing squeezing damage to the support base 1 and the mounting surface contact area, thus playing a certain protective role.

[0029] Guide blocks 16 are rotatably installed on the left and right sides of the support 3 and the left and right sides of the pressure plate 9. A spring 17 is fixedly installed between the two guide blocks 16 on the same side. When the guide blocks 16 work in conjunction with the spring 17, the spring 17 will deform and limit the pressure plate 9 when the threaded rod 5 rotates and squeezes the pressure plate 9, thus the spring 17 will quickly pull the pressure plate 9 back to its original position when the threaded rod 5 rotates back to its original position, thereby improving the ease of operation.

[0030] The spring 17 has a telescopic rod 18 inside. The two ends of the telescopic rod 18 are fixedly connected to two guide blocks 16 on the same side. The telescopic rod 18 can connect and support the two guide blocks 16 on the same side, thereby supporting and guiding the movement of the pressure plate 9, improving the stability of the movement and avoiding shaking.

[0031] A second spring 19 is fixedly installed on the side of the rotating arm 13. The end of the second spring 19 away from the rotating arm 13 is fixedly installed on the inner wall of the support 4. The second spring 19 is used in conjunction with the elastic force. When the two rotating arms 13 rotate relative to each other, the second spring 19 deforms. Therefore, the elastic force of the second spring 19 achieves a quick reset effect, improving the ease of operation.

[0032] A rubber sleeve 20 is fitted on the jaw clamp 14. The rubber sleeve 20 is attached to the outer surface of the jaw clamp 14. The rubber sleeve 20 can protect the surface of the workpiece and prevent damage to the surface of the workpiece when it is squeezed and fixed.

[0033] In use, the support base 1 is fixedly installed using bolts 2. When welding is required, the product is placed on the surface of the support 4 and positioned between the two jaw clamps 14. The hand crank 6 is turned, which drives the threaded rod 5 to rotate. The rotation of the threaded rod 5 will abut against the surface of the pressure plate 9 and drive the pressure plate 9 to rotate downward through the first rotating shaft 8. When the pressure plate 9 rotates downward, it will drive the bottom ends of the two rotating arms 13 to rotate outward. The rotating arms 13 rotate through the second rotating shaft 12, and the top ends of the two rotating arms 13 rotate inward. At the same time, the two jaw clamps 14 rotate inward, thereby clamping and fixing the product workpiece. At this time, the first spring 17 and the second spring 19 will deform simultaneously, and then welding can be performed. After the welding operation is completed, the hand crank 6 is turned in the opposite direction, which drives the threaded rod 5 to rotate and reset. At this time, the elastic force of the first spring 17 will stretch the pressure plate 9 to rotate and reset, and the elastic force of the second spring 19 will stretch the rotating arm 13 to rotate and reset, thereby releasing the product workpiece clamping and locking.
