Description

Technical Field

[0001] The present application relates to the technical field of instrument production, and in particular to a combined tooling for laser welding. Background Art

[0002] Instruments are devices used to measure and display parameters such as temperature, air pressure, electricity, blood pressure and flow, and are widely used in industrial automation control, process monitoring, quality inspection and scientific research. In the production process of instruments, laser welding technology is required to connect the components used to make up the instrument. In the laser welding process, it is often necessary to use professional fixtures to fix the product before the laser can be used to complete the welding.

[0003] However, traditional welding tools generally have the defects of large size and poor adaptability. Each product requires a set of dedicated welding tools. As the number of products continues to increase, the number of tools required will also increase, and the storage and production costs are high, which needs to be improved. Utility Model Content

[0004] In order to improve adaptability and reduce storage and production costs, the present application provides a combined tooling for laser welding.

[0005] The combined tooling for laser welding provided in this application adopts the following technical solution:

[0006] A combined tooling for laser welding comprises a mounting seat, a lining plate detachably connected to the mounting seat, a positioning plate for mounting a product to be welded, and a pressing piece for pressing the product to be welded and the positioning plate against the lining plate. A fixing block is detachably provided on the mounting seat, and the pressing piece is mounted on the fixing block.

[0007] By adopting the above technical solution, during processing, the product to be welded is fixedly mounted on the positioning plate, and the pressing piece can press the product to be welded tightly to improve the stability of the product during welding. When welding products of different models or sizes, the present application only needs to replace the positioning plate and the lining plate accordingly, so that a set of tooling can be adapted to multiple products, which not only has the advantage of high product adaptability, but also can effectively reduce the storage and production costs of tooling.

[0008] In addition, when positioning different products to be welded, different pressing pieces can be selected to be connected to the mounting seat to adjust the contact position between the pressing piece and the product to be welded and improve the positioning effect.

[0009] Optionally, the mounting seat is provided with an elongated fixing hole, a fixing bolt is passed through the fixing hole, and the fixing block is provided with a fixing screw hole that matches with the thread of the fixing bolt.

[0010] By adopting the above technical solution, the fixing block and the mounting seat are connected by fixing bolts, which has the effect of high connection strength and good stability. The fixing hole is designed in a long strip shape, so that the connection position of the fixing block and the mounting seat can be adjusted, so as to fine-tune the position of the pressing piece.

[0011] Optionally, the pressure member includes a base arranged on the fixed block, a first linkage block and a second linkage block rotatably connected to the base, a handle hinged to the first linkage block and the second linkage block, a connecting block fixedly connected to the first linkage block, and a pressure rod arranged on the connecting block, wherein the pressure rod is located on the side of the product to be welded away from the lining plate.

[0012] By adopting the above technical solution, when the handle is rotated, the first linkage block and the second linkage block will be linked accordingly, so that the connecting block drives the pressure rod to rotate toward or away from the side of the product to be welded, so as to tighten or loosen the product to be welded. The structure is simple and the operation is convenient.

[0013] Optionally, an elastic block is provided on the side of the pressure rod facing the product to be welded.

[0014] By adopting the above technical solution, the elastic block is separated between the pressure rod and the product to be welded, which not only protects the product to be welded from being squeezed and deformed by the pressure rod, but also enhances the pressing effect of the pressure piece on the product to be welded.

[0015] Optionally, the connecting block is provided with a plurality of connecting holes, one of which is passed through a connecting bolt, a connecting nut is threadedly connected to the connecting bolt, and the first linkage block is provided with an adjustment hole for the connecting bolt to pass through, and the adjustment hole extends along the length direction of the first linkage block.

[0016] By adopting the above technical solution, when installing the connecting block, first place the connecting block against the first linkage block and align one of the connecting holes with the adjustment hole; then pass the connecting bolt through the above connecting hole and the adjustment hole, and then connect the connecting nut to the connecting bolt. The connecting block can be fixed using the connecting bolt and the connecting nut, with a simple structure and high connection strength.

[0017] When positioning the product to be welded, people can also change the position of the connecting bolt through the adjustment hole to change the connection position between the connecting block and the first linkage block, so that the pressure rod is closer to the central axis of the product to be welded, which helps to improve the uniformity of force on the product.

[0018] Optionally, the connection block is provided with a plurality of through holes, the pressure rod is inserted into one of the through holes, and a first nut and a second nut are threadedly connected to the pressure rod, and the first nut and the second nut are respectively provided on both sides of the connection block.

[0019] By adopting the above technical solution, people can change the length of the pressure rod passing through the connecting block by changing the screwing positions of the first nut and the second nut to adapt to the pressure on products to be welded of different thicknesses, which is highly practical.

[0020] Optionally, a gasket is provided between the first nut and the connecting block, and between the second nut and the connecting block, and the gasket is sleeved on the outside of the pressure rod.

[0021] By adopting the above technical solution, the gasket is separated between the first nut, the second nut and the connecting block, which plays a role in dispersing the pressure of the first nut and the second nut on the connecting block, so that the connecting block is not easily broken due to excessive local force.

[0022] Optionally, the mounting base includes a base plate and a vertical plate detachably arranged on the base plate, the lining plate is installed on the vertical plate, and the base plate is provided with a plurality of through holes for bolts to pass through at intervals.

[0023] By adopting the above technical solution, bolts adapted to the through holes can pass through the through holes, so that the bottom plate can be fixedly installed at a desired position by means of the bolts, thereby improving the stability of the tooling itself.

[0024] Optionally, the vertical plate is provided with a mounting groove for the lining plate to extend into, and the lining plate is connected to the vertical plate by mounting bolts.

[0025] By adopting the above technical solution, the installation groove plays a role of indicating the position when the lining plate is installed, which is conducive to accurately controlling the installation position of the lining plate. The lining plate and the vertical plate are connected by installing bolts, which has the advantage of high connection strength.

[0026] Optionally, the lining plate is provided with a positioning groove for the positioning plate to extend into, the groove wall of the positioning groove is provided with a plurality of first limiting grooves, the positioning plate is provided with second limiting grooves which are equal in number to and correspond to the first limiting grooves one by one, the second limiting grooves and the corresponding first limiting grooves are jointly provided with limiting pins, and the limiting pins are used to prevent the positioning plate from rotating relative to the lining plate.

[0027] By adopting the above technical solution, when installing the positioning plate, first extend the positioning plate into the positioning groove, and align each second limiting groove with the first limiting groove one by one, and then insert the limiting pin into the first limiting groove and the corresponding second limiting groove in turn. The limiting pin can be used to prevent the relative rotation of the positioning plate and the lining plate, which helps to improve the stability of the positioning plate and the product to be welded.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:
