[0023] See also Figure 1-5 The utility model provides an embodiment: a clamping mechanism for a honing machine, comprising a housing 1, two sliders 4 movably arranged inside the housing 1, and a linear drive mechanism 3 for adjusting the distance between the two sliders 4, and a plurality of mounting portions 7 are arranged on the housing 1, which can be fixed on the honing machine by bolts;

[0024] Specifically, the linear drive mechanism 3 includes a screw rod 301 rotatably mounted inside the housing 1 and a driving member 302 driving the screw rod 301 to rotate. The external threads at both ends of the screw rod 301 are opposite, and the two sliders 4 are respectively threadedly connected to the screw rod 301. In this embodiment, the driving member 302 is specifically a hand wheel, which is mounted on the outside of the housing 1. The screw rod 301 can be driven to rotate by rotating the hand wheel, and then the two sliders 4 can be driven to move toward the middle or to both sides on the screw rod 301 at the same time, so as to achieve the clamping and loosening of the workpiece. Further, the driving member 302 can be set as a motor as needed;

[0025] Furthermore, a guide module 303 slidably connected to the slider 4 is provided inside the housing 1. The guide module 303 is specifically two slide bars horizontally fixed inside the housing 1. The slide bars are parallel to the screw rod 301. The slider 4 is slidably connected to the slide bars. Further, the guide module 303 can also be set as a slide rail fixed to the inner wall of the housing 1 as needed. The slider 4 is slidably connected to the slide rail, which can improve the stability of the horizontal movement of the slider 4.

[0026] The top of the slider 4 is installed with a baffle 5 through a connecting block 401, and a clamping plate 2 is fixed on one side of the top of the baffle 5. Slide holes 101 for accommodating the horizontal sliding of the connecting block 401 are provided on both sides of the top of the shell 1. The baffle 5 is used to block and close the slide hole 101. Specifically, the connecting block 401 is located in the middle of the bottom end of the baffle 5. The length of the baffle 5 is at least twice the length of the slide hole 101. When the connecting block 401 slides inside the slide hole 101, the baffle 5 is always located at the top of the slide hole 101 to block it, so as to prevent metal debris generated by the honing machine from entering the interior of the shell 1. In this embodiment, the clamping plate 2 is a vertical plate-like structure, and the clamping plate 2 can also be set to other shapes such as an arc as needed, or a protrusion or groove matching the surface of the workpiece can be set on the surface of the clamping plate 2 to achieve positioning of the workpiece.

[0027] In this embodiment, the connecting blocks 401 at the top of the two sliders 4 are not on the same straight line. Since the two baffles 5 have a certain length, the connecting blocks 401 and the baffles 5 fixed on the top of the connecting blocks 401 are arranged on two lines, so that the distance between the two clamping plates 2 can be minimized, and space for the baffles 5 to move can be reserved.

[0028] The top of the housing 1 is provided with a slide groove 102 for accommodating the baffle 5 to slide back and forth along the driving direction of the linear drive mechanism 3. The baffle 5 is slidably arranged inside the slide groove 102, which can limit the width direction of the baffle 5. The baffle 5 is movably arranged on the top of the connecting block 401 through the connecting member 6. The top of the connecting block 401 is provided with a connecting groove 402. Figure 4The connecting member 6 includes a connecting rod 601 fixed to the bottom end of the baffle 5 and a limit block 602 fixed to the bottom end of the connecting rod 601. The limit block 602 is slidably arranged inside the connecting groove 402, and the limit block 602 can rotate freely inside the connecting groove 402. An elastic reset member 603 is arranged inside the connecting groove 402 to push the baffle 5 to reset downward. Specifically, the cross-sectional size of the connecting rod 601 is smaller than the cross-sectional size of the limit block 602. A through hole matching the connecting rod 601 is provided at the top of the connecting groove 402. The elastic reset member 603 is a compression spring, the bottom end of which abuts against the limit block 602, and the top end abuts against the top end of the inner wall of the connecting groove 402. When the baffle 5 is pulled upward, the elastic reset member 603 can be compressed by the limit block 602. Further, the elastic reset member 603 can also be set as a tension spring as needed, which is set at the bottom end of the limit block 602. Figure 5 , rotate the baffle 5 180 degrees, and the limit block 602 rotates inside the connecting groove 402, so as to adjust the minimum value of the distance between the two clamping plates 2, which is suitable for clamping large-sized workpieces, meets different usage requirements, and is simple and convenient to adjust.

[0029] Working principle: When working, the screw rod 301 is driven to rotate by the driving member 302, and then the two sliders 4 are driven to move simultaneously to the middle or to both sides inside the shell 1, and then the distance between the two clamping plates 2 is adjusted to achieve the clamping and release of the workpiece. The baffle 5 always covers the top of the sliding hole 101 to block the sliding hole 101 to prevent external debris from entering the interior of the shell 1. When it is necessary to clamp and fix a large-sized workpiece, the clamping plate 2 is pulled upward, and the limit block 602 compresses the elastic reset member 603 upward to disengage the baffle 5 from the inside of the slide groove 102 and then rotate 180 degrees. Then the clamping plate 2 is released, and the elastic reset member 603 pushes the limit block 602 and the baffle 5 to reset downward. The baffle 5 is inserted into the inside of the slide groove 102. When in use, the distance between the two clamping plates 2 can be extended.
