DETAILED DESCRIPTION

[0023] In order to make the purpose and advantages of the utility model more clear and apparent, the utility model is specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model and does not strictly limit the specific protection scope requested by the utility model.

[0024] As Figures 1-4 shown, the technical scheme adopted by the utility model is specifically as follows: a clamp for laser marking accessories, comprising a workbench 1, a plurality of rectangular grooves 2 are formed on the top of the workbench 1 at four positions of left, right, front and back, a sliding fixing assembly is arranged in each rectangular groove 2, a sliding limit rod 3 is arranged on the sliding fixing assembly, a sliding groove 4 is formed on the top of the sliding limit rod 3, a moving assembly is arranged in the sliding groove 4, a clamping block 5 is arranged on the moving assembly, an elastic assembly is arranged on the clamping block 5, and a contact ball 6 is arranged on the elastic assembly.

[0025] The working principle is: first, the operator places the accessory that needs to be laser marked on the tabletop of the workbench 1. At this time, carefully observe the shape, size and contour features of the accessory, then according to the specific shape of the accessory, select the most suitable rectangular groove 2 from the multiple rectangular grooves 2 opened on the top left and right of the workbench 1, and make the sliding fixing assembly ascend and fix along the rectangular groove 2, then push the clamping block 5 towards the direction of the marking accessory through the moving assembly. In the initial stage of movement, the clamping block 5 gradually approaches the marking accessory. When the clamping block 5 contacts the accessory, continue to apply a pushing force, at which time the elastic assembly begins to play a role, as the pressure applied by the clamping block 5 increases, the elastic assembly is gradually compressed, generating a reverse spring force. This spring force enables the contact ball 6 to be in close contact with the surface of the marking accessory at an appropriate pressure. Due to the presence of the elastic assembly, even if the surface of the marking accessory is uneven or has local protrusions and depressions, the contact ball 6 can adaptively adjust the position and angle to achieve full adhesion with the surface of the accessory. In the entire clamping process, through the coordinated action of multiple clamping blocks 5, clamping force is applied to the marking accessory from different directions, so that the accessory is stably fixed in all directions. This all-around clamping and fixing method effectively prevents the accessory from moving, deflecting or loosening during laser marking due to external forces, vibrations or thermal deformation and other factors. In this way, no matter what complex shape the marking accessory presents, such as a circular, square, irregular or irregularly contoured shape, it can be stably and effectively clamped and fixed, thereby providing reliable protection for precise laser marking.

[0026] The sliding fixing assembly includes a sliding block 7 fixedly arranged on the inner wall of the rectangular groove 2 and a sliding groove 4 opened on the outer side of the sliding limiting rod 3, the sliding block 7 is arranged inside the sliding groove 4, and the bottom of the sliding limiting rod 3 is provided with a limiting disc 9, the limiting disc 9 is provided with a first magnetic surface, and the bottom of the workbench 1 is provided with a second magnetic surface which is attracted to the first magnetic surface.

[0027] When operating, people select the appropriate rectangular groove 2, then manually push the limiting disc 9, the limiting disc 9 drives the sliding limiting rod 3 to move and rise inside the sliding groove 4, and when the limiting disc 9 and the workbench 1 are in close contact, the first magnetic surface and the second magnetic surface are attracted and fixed.

[0028] At the same time, the area of the limiting disc 9 is larger than the area of the rectangular groove 2, so that the limiting disc 9 can be limited.

[0029] The moving assembly comprises a threaded rod 10 arranged inside the sliding groove 4, a threaded block 11 sleeved on the threaded rod 10, the clamping block 5 mounted on the top of the threaded block 11, and the threaded rod 10 penetrating out of the sliding groove 4 and being provided with a rotating disc 12 at one end, the rotating disc 12 driving the threaded rod 10 to rotate, the threaded rod 10 driving the sliding block 7 to move inside the sliding groove 4, so that the clamping block 5 moves to be fixed.

[0030] The elastic assembly comprises a plurality of circular grooves 13 arranged on the clamping block 5, a spring 14 arranged inside each circular groove 13, a piston disc 15 arranged on one side of the spring 14, a movable rod 16 arranged on one side of the piston disc 15, and the movable rod 16 penetrating out of the circular groove 13 at the end away from the piston disc 15 and being connected with the contact ball 6, when clamping, the contact ball 6 drives the movable rod 16 to make the piston disc 15 extrude the spring 14, so that the self-adaptive shape change is completed, and different shaped accessories can be fixed.

[0031] The contact ball 6 is provided with anti-skid lines, and the clamping and fixing effect is improved through the anti-skid lines.

[0032] The working principle of the utility model is as follows: firstly, the operator places the accessory needing laser marking on the table top of the workbench 1. At this time, the shape, size and contour features of the accessory are observed carefully, then, according to the specific shape of the accessory, the most suitable rectangular groove 2 is selected from the multiple rectangular grooves 2 arranged on the top of the workbench 1 at four positions of left, right, front and back, the sliding fixing assembly is fixed by ascending along the rectangular groove 2, and then the clamping block 5 is moved towards the direction of the marking accessory by the moving assembly. In the initial stage of movement, the clamping block 5 gradually approaches the marking accessory. When the clamping block 5 contacts the accessory, the pushing force is continuously applied, at this time, the elastic assembly starts to play a role, along with the increase of the pressure applied by the clamping block 5, the elastic assembly is gradually compressed, and the reverse elastic force is generated. The elastic force makes the contact ball 6 tightly adhere to the surface of the marking accessory with appropriate pressure. Due to the existence of the elastic assembly, even if the surface of the marking accessory is uneven or locally protruding or recessed, the contact ball 6 can also adaptively adjust the position and angle, so that the full adhesion to the surface of the accessory is realized. In the whole clamping process, through the synergistic effect of the multiple clamping blocks 5, the clamping force is applied to the marking accessory from different directions, so that the accessory is stably fixed in all directions. The omnibearing clamping and fixing mode effectively prevents the displacement, deflection or loosening of the accessory in the laser marking process due to the influence of factors such as external force, vibration or thermal deformation, so that no matter what complex shape the marking accessory presents, for example, circular, square, special-shaped or irregular contour shape, the marking accessory can be stably and effectively clamped and fixed, thereby providing reliable guarantee for the accurate laser marking.

[0033] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application. Structures, devices and operation methods not specifically described and explained in the present application are implemented according to conventional means in the art, unless otherwise specified and limited.
