Description

A retractable slider automatic polishing fixture Technical Fields

[0001] This utility model relates to the field of polishing equipment technology, specifically to an automatic polishing fixture with a retractable slider. Background Technology:

[0002] With the increasing demand for high-precision and high-efficiency surface treatment in the manufacturing industry, automated polishing technology has become an important development direction. Traditional polishing fixtures are mostly of fixed size, making it difficult to adapt to the needs of diverse workpieces, and they rely on manual operation, resulting in low efficiency and high cost. To meet the demands of modern manufacturing for flexibility, automation, and intelligence, there is an urgent need for a retractable automated polishing fixture. Invention content and utility model content:

[0003] The technical problem to be solved by this utility model is to provide a retractable slider automatic polishing fixture, which can improve polishing efficiency and is suitable for various bathroom product workpieces.

[0004] The technical solution of this utility model is to provide a retractable slider automatic polishing fixture, including a fixture body, wherein...

[0005] A mandrel is inserted at the front end of the fixture body. The mandrel can slide back and forth along the axial direction of the fixture body. The front end of the mandrel is conical and has a tapered structure towards the rear.

[0006] The front part of the fixture body is also provided with a movable slider, which cooperates with the mandrel and can slide radially along the fixture body;

[0007] A cylinder is connected to the rear end of the mandrel. When the mandrel moves backward under the drive of the cylinder, the outer diameter of the part of the mandrel that contacts the slider gradually increases, thereby driving the slider to move outward. In this way, after the workpiece is placed on the front end of the fixture body, the slider will tighten the workpiece for positioning.

[0008] Preferably, the rear end of the mandrel is cylindrical, and a limiting groove is recessed circumferentially at the rear end of the mandrel. The limiting groove has a specific length along the length of the mandrel. Correspondingly, a limiting member is provided radially on the fixture body, which extends into the limiting groove of the mandrel to limit its movement. Since continuous expansion of the slider may damage the parts, the limiting member can be used to limit the distance the mandrel moves.

[0009] Preferably, the limiting component is an internal hexagon screw, and there are two limiting components symmetrically distributed on the fixture body.

[0010] Preferably, there are two sliders symmetrically distributed at the front of the fixture body.

[0011] Preferably, the front part of the fixture body is provided with an I-shaped slide groove arranged radially, and the slider is slidably disposed in the I-shaped slide groove.

[0012] Preferably, the fixture body also has a mounting block at the rear end, which is connected to the robotic arm.

[0013] Preferably, the length of the limiting groove is 100-500mm.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model has a simple structure, enabling automatic adjustment and positioning of the fixture, reducing manual intervention; it can adapt to bathroom workpieces of different sizes, shapes and materials; it maintains high precision during automatic extension and retraction to ensure polishing quality; it maintains the stability of the fixture during high-speed polishing to avoid vibration or displacement; and it shortens adjustment time and improves production efficiency.

[0018] In the diagram: 1. Fixture body; 2. Mounting block; 3. Slider; 4. Mandrel; 5. Limiting component. Detailed implementation method:

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0020] As shown in Figures 1-2, a retractable slider automatic polishing fixture includes a fixture body 1, wherein...

[0021] A mandrel 4 is inserted at the front end of the fixture body 1. The mandrel 4 can slide back and forth along the axial direction of the fixture body 1. In this embodiment, the front end of the mandrel 4 is fully inserted into the fixture body 1 and remains flush with the front end face of the fixture body 1 before sliding. The front end of the mandrel 4 is conical and gradually narrows towards the rear. The rear end of the mandrel 4 is connected to the cylinder of the polishing equipment.

[0022] The front part of the clamp body 1 is also provided with a movable slider 3, which cooperates with the spindle 4 and can slide radially along the clamp body 1;

[0023] When the mandrel 4 is connected to the cylinder at the rear end, it moves backward under the drive of the cylinder. The outer diameter of the part of the mandrel 4 that contacts the slider 3 gradually increases, thereby driving the slider 3 to move outward. In this way, after the workpiece is placed on the front end of the fixture body 1, the slider 3 will tighten the workpiece for positioning.

[0024] In this embodiment, there are two sliders 3 symmetrically distributed at the front of the fixture body 1. The front of the fixture body 1 is provided with an I-shaped groove arranged radially, and the sliders 3 are slidably disposed in the I-shaped groove.

[0025] Since the continuous expansion of the slider 3 may damage the parts, as an implementation method, the rear end of the mandrel 4 is cylindrical, and a limiting groove is recessed along the circumference of the rear end of the mandrel 4. The limiting groove 4 has a specific length along the length of the mandrel. Correspondingly, a limiting member 5 is provided radially on the fixture body 1. The limiting member 5 extends into the limiting groove of the mandrel 4 to limit its movement. In this embodiment, the limiting member 5 is an internal hexagon screw. There are two limiting members 5, symmetrically distributed on the fixture body 1. The length of the limiting groove is 100-500mm, and different limiting groove lengths can be adapted to different bathroom fixture parts.

[0026] In one embodiment, the fixture body 1 is further provided with a mounting block 2 at its rear end, which is connected to the robotic arm of the polishing equipment.

[0027] The mounting block is installed on the robotic arm, and the fixture body is installed on the mounting block, so that the robotic arm can move and the fixture can move together. The mandrel is mounted on a cylinder, and the extension and retraction of the cylinder can drive the mandrel to extend and retract together. Because the mandrel has a reduced diameter structure when it moves backward, the slider will expand outward until it expands to the inner wall of the workpiece at the front end of the fixture body. Since the slider expands continuously, it may damage the workpiece. This utility model uses an internal hex screw to limit the distance of the mandrel movement, thereby realizing a polishing method of self-rotation and rotation, which can improve polishing efficiency and ensure polishing quality.

[0028] The above description only illustrates preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. Any equivalent structural or procedural modifications made using this specification are included within the patent protection scope of this invention.
