Description

Technical Field

[0001] This utility model relates to the field of cylinder technology for welding equipment, specifically a cylinder assembly for resistance welding equipment used for welding aluminum plates. Background Technology

[0002] Resistance welding equipment utilizes the resistance heat generated by the current passing through the contact points of the workpieces to achieve welding. Its basic principle is that the workpieces to be welded are clamped by electrodes, and pressure is applied while current is passed through them. When current flows between two metals, the resistance of the metals themselves and the resistance of the contact area generate heat, known as Joule heating. This heat and pressure are used to weld the metals together. In resistance welding equipment, the movement of the electrodes is often driven by a cylinder, thereby applying pressure to the metal plate; therefore, a cylinder needs to be installed on the equipment.

[0003] Traditional cylinders are often installed directly on top of the equipment. Since different devices require different strokes to drive the electrodes downward, different cylinders need to be customized for each device. This results in the need for custom-made cylinders during equipment installation, and the extension and retraction distance of the cylinders cannot be adjusted, which leads to certain limitations in the installation of traditional equipment cylinders. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cylinder assembly for resistance welding equipment used for welding aluminum plates, which has the advantages of adjustable cylinder extension distance and ease of use, thus solving the problems mentioned in the background art.

[0006] As a preferred technical solution of this utility model: the inner wall shape of the connecting seat is equal to the outer wall shape of the cylinder body, and there are two support rods, which are respectively installed on both sides of the outer wall of the fixing plate.

[0007] As a preferred technical solution of this utility model: the two ends of the outer wall of the reset spring are respectively connected to the outer walls of the moving rod and the limiting rod, and the reset spring is made of high carbon steel.

[0009] As a preferred technical solution of this utility model: the outer wall of the locking rod passes through the inner cavity of the driving block, and the outer wall of the connecting rod is movably sleeved in the inner cavity of the limiting plate.

[0010] As a preferred technical solution of this utility model: the outer wall of the driving block passes through the inner cavity of the connecting seat and contacts the outer wall of the locking block, and the outer wall of the telescopic shaft passes through the inner cavity of the fixed seat.

[0021] Please see Figure 1 - Figure 5 A cylinder assembly for resistance welding equipment for welding aluminum plates includes a fixed base 1, a fixed plate 2 fixedly mounted on the top of the fixed base 1, a support rod 3 fixedly mounted on the top of the fixed plate 2, a connecting seat 5 movably sleeved on the outer wall of the support rod 3, a cylinder body 4 fixedly mounted on the inner wall of the connecting seat 5, a locking hole 6 opened on the outer wall of the support rod 3, a limit rod 7 fixedly mounted on the outer wall of the connecting seat 5, a return spring 8 movably sleeved on the outer wall of the limit rod 7, a moving rod 9 movably sleeved on the outer wall of the return spring 8, a locking block 10 fixedly mounted on the outer wall of the moving rod 9, a driving block 11 movably sleeved on the inner cavity of the connecting seat 5, a limit plate 12 fixedly mounted on the outer wall of the connecting seat 5, a connecting rod 13 fixedly mounted on the outer wall of the driving block 11, a locking rod 14 movably sleeved on the outer wall of the connecting seat 5, and a telescopic shaft 15 movably sleeved on the inner cavity of the cylinder body 4.

[0022] In the above structure, by setting the fixed plate 2 and the connecting seat 5, by installing the connecting seat 5 on the outer wall of the fixed plate 2, and by adjusting the position of the connecting seat 5 on the outer wall of the support rod 3, the installation position of the cylinder body 4 is adjusted, thereby adjusting the distance between the cylinder body 4 and the fixed seat 1, so as to adjust the length of the telescopic shaft 15 extending downward from the inner cavity of the fixed seat 1, so as to better drive the resistance welding head to move downward.

[0023] In a preferred embodiment: the inner wall shape of the connecting seat 5 is equal to the outer wall shape of the cylinder body 4, and there are two support rods 3, which are respectively installed on both sides of the outer wall of the fixing plate 2.

[0024] In the above structure, the connecting seat 5 is sleeved on the outer wall of the support rod 3 installed on both sides of the outer wall of the fixed plate 2. When it is necessary to adjust the working height of the cylinder body 4, the position of the connecting seat 5 on the outer wall of the support rod 3 is adjusted, so that the height of the cylinder body 4 can be adjusted up and down.

[0025] In a preferred embodiment, the two ends of the outer wall of the reset spring 8 are connected to the outer walls of the moving rod 9 and the limiting rod 7, respectively, and the reset spring 8 is made of high carbon steel.

[0026] In the above structure, the reset spring 8 provided on the outer wall of the limiting rod 7 resets the locking block 10 under the action of the reset spring 8, so that the locking block 10 can enter the inner cavity of the locking hole 6, thereby fixing the position of the connecting seat 5 and thus fixing the position of the cylinder body 4.

[0027] In a preferred embodiment: the outer wall shape of the drive block 11 near the locking block 10 matches the outer wall shape of the locking block 10, and the outer wall shape of the locking block 10 matches the inner wall shape of the locking hole 6.

[0028] In the above structure, the driving block 11 provided in the inner cavity of the connecting seat 5 can drive the locking block 10 when the driving block 11 is pushed to move downward, so that the outer wall of the locking block 10 enters the inner cavity of the locking hole 6, thereby fixing the position of the connecting seat 5 and so that the connecting seat 5 can be stably installed on the outer wall of the support rod 3.

[0029] In a preferred embodiment: the outer wall of the locking rod 14 passes through the inner cavity of the drive block 11, and the outer wall of the connecting rod 13 is movably sleeved in the inner cavity of the limiting plate 12.

[0030] In the above structure, by installing a locking rod 14 on the top of the connecting seat 5, the driving block 11 is pushed downward to drive the locking block 10, so that the outer wall of the locking block 10 enters the inner cavity of the locking hole 6. Then, the outer wall of the locking rod 14 is inserted into the inner cavity of the driving block 11 to lock the driving block 11, thereby making the locking block 10 stably enter the inner cavity of the locking hole 6 and lock the connecting seat 5.

[0031] In a preferred embodiment: the outer wall of the drive block 11 passes through the inner cavity of the connecting seat 5 and contacts the outer wall of the locking block 10, and the outer wall of the telescopic shaft 15 passes through the inner cavity of the fixed seat 1.

[0032] In the above structure, the driving block 11 provided in the inner cavity of the connecting seat 5 can drive the locking block 10 to move under the action of the outer wall of the driving block 11 when the driving block 11 is pushed to move downward, so that the outer wall of the locking block 10 enters the inner cavity of the locking hole 6, thereby fixing the connecting seat 5 and ensuring that the connecting seat 5 can be stably installed on the outer wall of the support rod 3.

[0033] Working principle: During use, the above equipment is installed on the top of the fixed base 1 by installing the fixed plate 2. When the installation position of the cylinder body 4 needs to be adjusted, the distance of the telescopic shaft 15 extending outward from the inner cavity of the fixed base 1 can be adjusted. Only the installation position of the connecting seat 5 needs to be adjusted. By pulling the locking rod 14 outward, the locking rod 14 is disengaged from the inner cavity of the drive block 11. Then, the drive block 11 can be pulled upward, and the drive of the locking block 10 is released. The locking block 10 will move out of the inner cavity of the locking hole 6 under the traction of the limit rod 7. At this time, the fixing of the connecting seat 5 can be released. The installation position of the connecting seat 5 on the outer wall of the support rod 3 is adjusted. After the adjustment is completed, the drive block 11 is pushed downward to drive the locking block 10, so that the locking block 10 re-enters the inner cavity of the support rod 3, thereby fixing the connecting seat 5. This ensures that the connecting seat 5 is stably installed on the outer wall of the support rod 3, ensuring the stable fixing of the cylinder body 4, and thus allowing the working distance of the telescopic shaft 15 to be adjusted.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
