Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 8 The present invention provides a technical solution: a grinding limit device for a surgical blade, comprising a clamping seat 1, a positioning plate 2 arranged at the top of the clamping seat 1, a pair of limit end blocks 3 located at the upper end of the positioning plate 2, both ends of the clamping seat 1 are provided with limit grooves, both ends of the positioning plate 2 are provided with positioning frames 21, the positioning frames 21 are symmetrically arranged at the top of the clamping seat 1, and support plates 25 are installed on the positioning frames 21, and the support plates 25 are provided with card slots, and both ends of the support plates 25 are provided with rotating disks 22, and a straight rod is fixedly connected between the rotating disks 22, and the straight rod is rotatably carded in the card slot, and the positioning plate 2 is installed on the straight rod;

[0033] The limiting end blocks 3 are all arranged at the upper end of the positioning plate 2, and a pair of arc grooves are opened on the surface of the positioning plate 2. A telescopic rod is installed at the bottom of the limiting end block 3, and the telescopic rod is clamped in the arc groove. A supporting pad 4 is installed at the bottom of the limiting end block 3. When the blade needs to be ground, the surgical blade can be clamped and positioned with the help of the limiting end block 3 and the supporting pad 4, and the clamping seat 1 can be clamped on the grinder, and the surface of the surgical blade can be quickly ground and polished with the help of the grinder. The offset can be adjusted with the help of the positioning plate 2 angle, and it can be adjusted according to different inclination angles of the surface of the surgical blade to ensure the processing quality of the equipment.

[0034] like Figure 2 As shown, in order to improve the overall processing efficiency, a welding plate 211 is provided on the side of the positioning frame 21 away from the support plate 25, and a rectangular groove is provided on the welding plate 211. Scale lines are provided on the outer wall of the rotating disk 22, and the position of the rectangular groove corresponds to the scale lines. With the help of the scale lines, the angle of the positioning plate 2 can be quickly adjusted to perform processing according to the inclination angles of different surgical blades;

[0035] The support plates 25 are all provided with limit rods, and the limit rods are against the outer wall of the straight rods for auxiliary positioning. The limit rods can be against the straight rods to ensure stability during tilting.

[0036] like Figure 2 As shown, when the processing is completed and the fixture is cleaned, a fixing groove begins to appear on the positioning plate 2, and docking grooves 23 are provided at both ends of the fixing groove, and the docking grooves 23 are inclined. Separation screen plates 24 are provided on both sides of the positioning plate 2, and the separation screen plates 24 are stuck in the docking grooves 23. The separation screen plates 24 are grid-shaped, and the cross-section of the separation screen plates 24 is stepped.

[0037] like Figure 3 As shown, during the clamping process, the surface of the surgical blade is easily damaged due to excessive holding force, a sliding groove is provided on the surface of the limiting end block 3, and a push pressure plate 31 is movably provided inside the sliding groove, a positioning bolt is inserted at one end of the push pressure plate 31, and a straight groove is provided inside the sliding groove for cooperating with the positioning bolt for limiting, a pair of buffer end blocks 32 are inserted at the bottom of one end of the limiting end block 3, the buffer end block 32 is used for auxiliary clamping, and the buffer end block 32 can increase the contact area with the blade during the clamping process with the help of its own elasticity, thereby ensuring the stability of the clamping, and also avoiding the accidental situation that the blade surface has clamping marks or even bending due to rigid contact.

[0038] In order to prevent displacement during the clamping process, a positioning ring 33 is movable inside the limiting end block 3, and a limiting rod is inserted inside the positioning ring 33. The limiting rod is used to abut against the through hole of the surgical blade to assist in limiting. The limiting rod can be quickly positioned to determine the approximate clamping position and angle, thereby improving processing efficiency.

[0039] like Figure 4 As shown, the debris generated during the grinding process is prone to accumulation, and a plurality of support blocks 42 are installed at the bottom of the support pad 4. The support blocks 42 are symmetrically arranged at the bottom of the support pad 4, and a dust shield 43 is clamped between the support blocks 42. The dust shield 43 is used for debris recovery;

[0040] A plurality of support shafts 46 are fixedly connected to the surface of the dust shield 43, and a plurality of toggle rods 461 are clamped on the top of the support shaft 46. The toggle rods 461 and the support shaft 46 are vertically staggered. The toggle rods 461 are elastic, and the staggered support shafts 46 and toggle rods 461 can facilitate the accumulation of metal chips for subsequent unified processing.

[0041] like Figure 5 As shown, since the debris generated by grinding is not cleaned up in time, it will affect the subsequent clamping and processing. Fixed grooves are opened on both sides of the support pad 4, and the top of the fixed groove is installed with a clamping plate 41. A pair of reset shafts 412 are fixedly connected to the clamping plate 41. The reset shafts 412 are symmetrically arranged and a transmission shaft 44 is installed at the bottom. A bolt hole is opened on the top of the clamping plate 41, and a bolt shaft 411 is inserted into the contour bolt hole. The bottom of the bolt shaft 411 is against the top of the transmission shaft 44. A welding frame 45 is installed at the bottom of the transmission shaft 44. The position of the bolt shaft 411 is adjusted to push the transmission shaft 44 to a suitable angle, which can not only ensure the stability of the subsequent clamping, but also leave a gap for chip removal.

[0042] A conveyor belt 451 is movably provided inside the welding frame 45, and a conveyor tooth is provided on the inner wall of one side of the conveyor belt 451. A rotating shaft 47 is rotatably provided inside the conveyor belt 451, and a gear groove is opened on the rotating shaft 47, and the gear groove corresponds to the position of the conveyor tooth. A storage tube 471 is installed between the rotating shafts 47. The generated debris can be quickly transmitted to the dust shield 43 and the storage tube 471 under the action of the airflow generated by the operation of the machine tool, and the metal chips can be diverted and separated to prevent them from accumulating near the blade and affecting the subsequent clamping and positioning.

[0043] like Figure 7As shown, in order to recycle precious metal scraps, an arc plate 472 is provided inside the storage tube 471. The arc plate 472 is arc-shaped and installed between the rotating shafts 47. The cross section of the storage tube 471 is "C"-shaped. The position of the arc plate 472 corresponds to the notch of the storage tube 471. A plurality of conical holes are opened on the top of the arc plate 472, and a blocking cover is provided on the conical hole. A plurality of elastic ropes are fixedly connected to the inner wall of the arc plate 472, and the elastic ropes are connected to both ends of the blocking cover, which can move the rotating shaft 47 on one side. Rotation can move the internal conveyor belt 451, thereby moving the entire rotating shaft 47 and making one side of the arc plate 472 face downward, so that the blocking cover can fall between the toggle rods 461 under the action of gravity, and the residual metal chips inside can fall off. Continuously pulling the rotating shaft 47 to rotate can shake off the accumulated metal chips on the dust shield plate 43, and can be collected and cleaned in a unified manner. After the chip removal is completed, the storage tube 471 is reset, and the blocking cover can be reset to the inside of the tapered hole under the action of the elastic rope.

[0044] Working principle: first, when it is necessary to grind the blade, the surgical blade can be clamped and positioned with the help of the limiting end block 3 and the supporting pad 4, and the clamping seat 1 can be clamped on the grinding machine, and the surface of the surgical blade can be quickly ground and polished with the help of the grinding machine, and the offset can be adjusted with the help of the positioning plate 2, and it can be adjusted according to the different inclination angles of the surface of the surgical blade to ensure the processing quality of the equipment, and during the clamping process, the angle of the rotating shaft 47 can be adjusted according to the material of the surgical blade and the grinding feed amount, so that the storage tube 471 is offset and can be against the bottom of the surgical blade, so that the metal chips generated by grinding enter the interior of the storage tube 471 along the arc plate 472, which is convenient for subsequent separation and cleaning, and reduces the mixing of metal chips of different materials inside the machine tool;

[0045] Then, during the clamping process, the position of the positioning ring 33 can be adjusted during clamping, and the limiting rod inside the positioning ring 33 is inserted into the connection hole of the blade to assist in positioning. At the same time, the buffer end block 32 is pressed against one end of the blade to assist in clamping and ensure the stability of the clamping. The straight rod between the rotating disks 22 can be adjusted according to the grinding angle, so that the positioning plate 2 can be offset as a whole, without the need for additional pads, etc., which is convenient for operators to perform clamping and positioning;

[0046] Finally, when the debris that falls into the storage tube 471 needs to be cleaned, the rotating shaft 47 on one side can be rotated to move the internal conveyor belt 451, thereby moving all the rotating shafts 47 and making one side of the arc plate 472 face downward. The blocking cover can fall between the toggle rods 461 under the action of gravity, and the residual metal chips inside can fall off. The rotating shaft 47 can be continuously pulled to rotate, and the accumulated metal chips inside can be shaken off onto the dust shield 43, so that they can be collected and cleaned together. After the chip removal is completed, the storage tube 471 is reset, and the blocking cover can be reset to the inside of the tapered hole under the action of the elastic rope.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
