Description

Technical Field

[0001] This utility model relates to the field of laser engraving processing technology, specifically to an end face support and a four-in-one clamp. Background Technology

[0002] In the field of laser engraving, a rotary motor is often used to drive a fixture to rotate the workpiece. However, current end-face supports have significant limitations in workpiece support methods. Most existing end-face supports use rollers to roll and support the workpiece. This method is only suitable for some conventionally shaped workpieces. When dealing with spherical, easily sliding, or special workpieces that are thicker at one end than the other, its drawbacks become apparent. For spherical or easily sliding workpieces, the lack of an effective positioning and constraint mechanism makes them prone to displacement during processing, resulting in a significant reduction in processing accuracy. For workpieces that are thicker at one end than the other, rollers cannot provide uniform and stable support, which also fails to meet the requirements of high-precision processing. This severely limits the types of workpieces that can be processed and greatly reduces processing flexibility.

[0003] Furthermore, existing end face supports cannot be adaptively adjusted according to the size of the workpiece, and the fixed structure of traditional end face supports cannot meet this requirement. In actual production, if workpieces of various sizes need to be processed, it is necessary to frequently change end face supports of different specifications, which not only increases production costs, but also consumes a lot of time and manpower, seriously affecting production efficiency.

[0020] 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.

[0021] Please see Figure 1-3 In this embodiment, an end face bracket includes a locking plate 7. A pair of protruding plates are installed on the top side of the locking plate 7. A grooved rod 10 is connected between the protruding plates by a rotating shaft. The back of the bottom of the grooved rod 10 is arc-shaped, and the right protruding plate extends to the side hole of the grooved rod 10 by a screw to achieve rotation locking and positioning. At the same time, the grooved rod can be erected and lowered.

[0022] The grooved rod 10 has a lifting assembly installed inside. The lifting assembly includes a lead screw nut 11 installed inside the grooved rod 10 and a drive component that drives the lead screw nut 11 to run. The drive component is a handle 12 fixed to the top of the lead screw of the lead screw nut 11, or a motor installed on the top of the grooved rod 10 to drive the lead screw to rotate. Rotating the handle 12 can drive the lead screw nut 11 to rotate. The nut end of the lead screw nut 11 is fixed with a T-shaped moving block 13. When the handle or the motor drives the lead screw to rotate, it can drive the moving block 13 to rise and fall.

[0023] In addition, the movable block 13 is provided with an arc-shaped groove 14. The tail end of the dial plate 15 is rotatably mounted on the movable block 13 by a screw. The tail end of the dial plate 15 is also provided with an adjusting screw, and the end of the adjusting screw is located in the arc-shaped groove 14. Loosening the adjusting screw can adjust the dial plate 15 so that the dial plate is horizontal or vertical. The head end of the dial plate 15 is rotatably mounted with a detachable suction cup 16 or multiple rollers 18. The suction cup 16 is used to adsorb spherical and easily sliding workpieces, and the rollers 18 are used for rolling support of conventional workpieces.

[0024] In Embodiment 1, the locking plate 7 of the end face bracket is installed on the base 1. The base 1 is fixed with a support 17 by screws. A drive motor 2 is installed on the support 17. The drive end of the drive motor 2 is provided with a workpiece clamping assembly, which is a pneumatic gripper 3 or an electric gripper. The inner side of the gripper is provided with an anti-slip pad. When the workpiece length is appropriate, the workpiece can be directly clamped and fixed by the pneumatic gripper or the electric gripper. The drive motor drives the pneumatic gripper or the electric gripper to rotate, thereby causing the workpiece to rotate.

[0025] In Embodiment Two, combined with Embodiment One, the bottom of the locking plate 7 is equipped with two pairs of bearings 8 or rollers that slide together on both sides of the base 1. Simultaneously, a hole block 9 is fixed between the left pair of bearings 8 at the bottom of the locking plate 7. The hole block 9 is locked to the base 1 by screws. At this time, a suction cup 16 is installed on the lever plate 15. Therefore, when the tail end of the workpiece is spherical or easily sliding, the workpiece is first clamped and fixed using Embodiment One. Then, the locking plate is moved so that the suction cup approaches the tail end of the workpiece and adheres to it, thus providing support and improving the stability of the workpiece rotation driven by the gripper via the drive motor.

[0026] In Example 3, combining Examples 2 and 1, the suction cup 16 on the dial plate 15 is removed and replaced with multiple rollers 18. First, the gripper clamps and fixes the head end of the workpiece. The rollers are installed on the dial plate. The sliding screw of the locking plate is loosened, so that the rollers move to a position below the tail end of the workpiece. The rotating handle is rotated to raise the moving block, so that the rollers contact the workpiece and provide support. The drive motor drives the workpiece to rotate, and the rollers cooperate to provide rolling support.

[0027] In Example 4, combined with Examples 1, 2, and 3, the base 1 has two rows of positioning holes, each with two pairs of bearing seats 4 secured by screws. Rollers 5 are rotatably connected between opposing bearing seats 4. A belt drive device 6 is connected between the shaft end of the drive motor 2 and the two sets of rollers 5. The support 17 has an adjustable tension wheel 19, and also has an elongated adjustment hole. The tension wheel 19 is installed in the elongated adjustment hole by a locking element and can slide along it for adjustment. In this configuration, when a workpiece is clamped and fixed by a pneumatic gripper and supported by a suction cup or roller, if the workpiece is heavy, its bottom can be brought into contact with the two rollers, improving bottom support. When the gripper is driven to rotate by the drive motor, the belt drive device also drives the rollers to rotate, thereby assisting in the rotation of the workpiece and improving rotational stability.
