Description

Technical Field

[0001] This utility model relates to the field of laser cutting feeding accessories technology, specifically a three-station hand clamp. Background Technology

[0002] Laser processing is a processing technology that uses a high-power laser beam to cut, weld, surface treat, drill, and micro-machine workpieces. Due to its advantages such as small spot size, concentrated energy, small heat-affected zone, and non-contact with the workpiece, laser processing has been widely used as an advanced manufacturing technology in the fields of automobiles, electronics, electrical appliances, aerospace, metallurgy, and machinery manufacturing.

[0003] Laser cutting machines are high-precision processing equipment. They can process very small wedge angles, high aspect ratio cuts, irregular shapes, etc., with small kerfs, smooth cut surfaces, and high cutting accuracy.

[0004] Currently, laser cutting machines mainly process sheet metal and long tubes. When processing irregularly shaped short tubes, there is no automated feeding equipment yet. Raw materials can only be put in one by one for laser cutting. Manual feeding is very time-consuming and results in low processing efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of low processing efficiency when laser processing irregularly shaped short tubes by feeding them one by one, and to design a three-station hand clamp.

[0006] This utility model provides the following technical solution: a three-station hand chuck fixture, including a base, a drive motor, a reducer, a manual chuck, a fixture bracket, and product fixtures. Multiple reducers are installed on one side of the base, the drive motor is installed at the bottom of the reducer and is connected to the reducer in a transmission manner, the manual chuck is installed on the output shaft of the reducer, the fixture bracket is installed on the manual chuck, and multiple product fixtures are installed on the fixture bracket.

[0007] Preferably, a dust baffle is installed on the base.

[0008] Preferably, the speed reducer is equipped with a speed sensor.

[0009] Preferably, the fixture support includes a support body, a fixing rod, and a positioning groove. The fixing rod is located on one side of the support body and is fixed by a manual chuck. Multiple positioning grooves are formed on the support body, and the product fixture is fixed in the positioning grooves.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by setting multiple driving devices at the same time, and setting multiple product fixtures on each driving device, multiple raw materials can be loaded and laser processed in one go, which greatly improves the processing speed of small-sized irregular raw materials.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] like Figures 1-6 As shown, this utility model provides a technical solution: a three-station hand chuck fixture, including a base 1, a drive motor 2, a reducer 3, a manual chuck 4, a fixture bracket 5, and product fixtures 6. The base 1 is fixed at the processing position of the laser cutting machine. Multiple reducers 3 are installed on one side of the base 1. The drive motor 2 is installed at the bottom of the reducer 3 and is connected to the reducer 3 in a transmission manner. The manual chuck 4 is installed on the output shaft of the reducer 3. The fixture bracket 5 is installed on the manual chuck. Multiple product fixtures 6 are installed on the fixture bracket 5. The material to be processed is manually placed on the product fixture 6, and finally processed by the laser.

[0015] A dust baffle 7 is installed on the base 1. The dust baffle 7 is located in front of the drive motor 2 to prevent the waste generated by laser processing from damaging the drive motor.

[0016] Specifically, the fixture bracket 5 includes a bracket body 51, a fixing rod 52, and a positioning groove 53. The fixing rod 52 is located on one side of the bracket body 51 and is fixed by a manual chuck 4. Multiple positioning grooves 53 are formed on the bracket body 51, and the product fixture 6 is fixed in the positioning groove 53. The product fixture 6 is fixed in the positioning groove 53 by bolts, so that the product fixture 6 can be easily replaced to adapt to products of different shapes.

[0017] A rotation sensor 31 is provided on the top of the reducer 3, and a light-blocking rod is provided on the output shaft turntable of the reducer 3. When the output shaft turntable rotates, the light-blocking rod periodically blocks the rotation sensor 31, thereby accurately counting the rotation of the fixture support 5.

[0018] In use: First, manually place the raw material onto the product fixture 6. Then, start the drive motor 2, which drives the fixture support 5 to rotate via the reducer 3 to adjust the posture of the raw material on the product fixture 6. Then, the three-axis module and laser of the laser cutting machine move to process the raw material, and process multiple raw materials on the product fixture 6 at one time. After processing, the material can be reloaded and processed at once. In this way, multiple materials can be loaded and processed at one time, which improves processing efficiency.

[0019] 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 embodiments and their equivalents.
