Description

Technical Field

[0001] This utility model relates to a positioning welding device, and in particular to a rapid positioning device for a drip tray. Background Technology

[0002] Welding is a common method in machining to connect several independent workpieces. However, without a proper positioning fixture, the welding quality is extremely unstable, the workpieces are difficult to position, and they are prone to falling off.

[0003] A drip tray typically consists of a rectangular tray and L-shaped bends at both ends. During the manufacturing process, it's crucial to ensure the flatness of the two bends to control the aesthetics and size of the weld scars after welding. Traditionally, this method involves manually clamping the tray with pliers and then aligning it manually before welding. This method has significant drawbacks: firstly, manual operation is inconvenient and leads to high manufacturing costs; secondly, it's difficult to ensure the two bends are on the same plane, failing to meet the parallelism and dimensional requirements of the product. Furthermore, additional shaping is required after welding, further increasing the production cost of the drip tray. From both a precision and labor cost perspective, this method is unfavorable for mass production. Utility Model Content

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0028] Please see Figures 1-3This utility model provides a quick positioning device for a drip tray, including a base plate 1 for placing the drip tray 7; the base plate 1 is provided with a positioning block 2 for initially positioning the drip tray 7 and a clamping assembly 3 for clamping the drip tray 7. The base plate 1 is mounted on a base 6, and the bottom of the base 6 is provided with a support foot 61.

[0029] Furthermore, the base plate 1 is provided with positioning blocks 2 on the rear, left, and right sides of the drip tray 7. The positioning blocks 2 are arranged around the outer periphery of the drip tray 7 to position the drip tray 7 on the base plate 1. The front edge of the drip tray 7 is provided with a downwardly extending extension piece, and the base plate 1 is provided with a positioning groove 11 that matches the extension piece.

[0030] Furthermore, the base plate 1 is also provided with two clamping components 3, which are respectively located at the corners of the drip tray 7, for pressing the two bent ends 71 ​​of the drip tray 7 respectively. (Reference) Figures 4-6 The clamping assembly 3 includes a fixed base 31, a hinge base 32, a cylinder 33, a first connecting rod 34, a second connecting rod 35, a pressure rod 36, and a pressure head 37. The hinge base 32 is fixed to the front end of the fixed base 31, and the cylinder 33 is obliquely mounted on the fixed base 31 with its telescopic end facing upwards. One end of the first connecting rod 34 and the second connecting rod 35 is hinged to the telescopic end of the cylinder 33, and the other end of the first connecting rod 34 is hinged to the hinge base 32. The other end of the second connecting rod 35 is hinged to the middle of the pressure rod 36, and one end of the pressure rod 36 is hinged to the hinge base 32. The length of the second connecting rod 35 is less than the length of the first connecting rod 34. The hinge point between the first connecting rod 34 and the hinge base 32 is located obliquely below the hinge point between the pressure rod 36 and the hinge base 32.

[0031] Furthermore, the pressure head 37 is detachably mounted on the pressure rod 36. The pressure rod 36 has a groove 361 extending along its length; a connecting rod 371 is fixed to the pressure head 37, and the connecting rod 371 is slidably disposed within the groove 361. The connecting rod 371 is equipped with a locking element 372 for locking the height and position of the pressure head 37 relative to the pressure rod 36. The locking element 372 consists of a clamping plate and a bolt arranged vertically opposite each other.

[0032] Furthermore, at least one manual quick clamp 4 is also provided on the base plate 1.

[0033] Furthermore, the base plate 1 is also provided with a reversing valve for controlling the cylinder 33.

[0035] Instructions for use: The operator first inserts the drip tray 7 between the positioning blocks 2 on the back, left and right sides of the base plate 1, ensuring that the two bent ends of the drip tray 7 are tightly fitted with the positioning blocks 2 on both sides, thus completing the initial placement of the drip tray 7. Then, by controlling the reversing valve, the cylinder 33 is started, which drives the first connecting rod 34 and the second connecting rod 35 to move, thereby driving the pressure head 37 on the pressure rod 36 to press down, so that the pressure head 37 presses the bent ends 71 ​​at both ends of the drip tray 7, thus achieving a stable clamping of the corners of the drip tray 7. Then operate the manual quick clamp 4 to press it against the middle top surface of the drip tray 7 to further fix the drip tray 7. At the same time, turn on the welding shielding gas introduction device 5 to allow the welding shielding gas to be delivered to the welding area of ​​the drip tray 7 through the manifold block single row three-branch five-way connector and gas pipe to protect the welding area. After completing all the above steps, welding can be performed on the drip tray 7. During the welding process, each positioning component keeps the drip tray 7 clamped, and the welding shielding gas continues to act to ensure the welding quality.

[0036] In summary, this invention uses two clamping components to precisely position the two bent ends of the drip tray, ensuring they are on the same plane and meeting the processing requirements for product parallelism and dimensions. Furthermore, the clamping components have a simple and ingenious structure, high space utilization, and can be synchronously clamped or released by controlling the two cylinders. The height and position of the clamping heads are adjustable, ensuring synchronous pressing of the two bent ends. Therefore, this invention effectively overcomes the various shortcomings of existing technologies and has high industrial application value.
