DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figure 1 As shown, the utility model provides an internal gear grinding structure for machine tools, including a transition plate 1 installed on the machine tool equipment, so as to transform the old ordinary machine tools, and the top of the transition plate 1 is provided with a base 5 and a magnetic powder brake 2 through bolts. The magnetic powder brake 2 is arranged at the rear side of the base 5. A clamp 6 is provided on the top of the transition plate 1. The clamp 6 includes an end body 601, and a shaft body 603 is fixedly provided at the rear end of the end body 601. The base 5 is sleeved on the shaft rod of the shaft body 603 through two single-row tapered roller bearings 10. The middle part of the shaft body 603 is provided with a thread for installation and fixing. A fixing nut 8 is provided on the rear side of the base 5, and the fixing nut 8 is threadedly sleeved on the middle part of the shaft body 603 through a threaded connection, and is used to axially position the shaft body 603 on the base 5. The rear end of the shaft body 603 is connected to the magnetic powder brake 2 through a cross slider coupling 4. Under the action of the cross slider coupling 4, the magnetic powder brake 2 and the clamp 6 can rotate synchronously even if they are not coaxial.

[0027] The front end of the end body 601 is provided with a plurality of pressing plates 7 by bolts, and the parts are fixed to the end body 601 by the pressing plates 7. The front and rear sides of the base 5 are provided with step holes for installing a single-row tapered roller bearing 10. A skeleton-type sealing ring 9 is provided inside the step hole.

[0028] The transition plate 1 is detachably mounted on the machine tool equipment to transform the old ordinary machine tool. After the transformation, the inner gear ring part is fixed to the end body 601 through the pressure plate 7, so that the inner gear parts can be ground. After the processing is completed, the magnetic powder brake 2 is used to complete the rotation brake of the workpiece. In this way, without increasing the existing machine tool equipment, the ordinary machine tool is transformed into a tooth grinding processing equipment that can perform internal gear parts, which effectively improves the processing range of the existing machine tool equipment, avoids the waste of resources of the old machine tool, and reduces the production cost of such parts. In addition, the grinding structure is simple to clamp, which greatly improves the processing efficiency.

[0029] The grinding process produces debris that is difficult to clean. Figure 1 , 2 As shown in FIGS. 5 and 6, a blind hole 602 for mounting parts is provided at the front end of the end body 601. Six through holes 604 penetrating the end body 601 are provided on the rear wall inside the blind hole 602. The through holes 604 are used for weight reduction of parts and chip removal.

[0030] The rear side of the base 5 is provided with a fan assembly 12, and the fan assembly 12 includes a mounting sleeve 1201 sleeved on the outer end of the shaft body 603. The outer end of the mounting sleeve 1201 is provided with a fastening bolt through a thread, so that the fan assembly 12 can be installed or removed. A plurality of blades 1202 are fixedly provided at the outer end of the mounting sleeve 1201, and the rotation of the blades 1202 can drive air flow.

[0031] The parts are fixed inside the blind hole 602, and the debris generated during the grinding process will fall into the blind hole 602. During the grinding process, the fixture 6 will rotate as a whole and drive the fan blade assembly 12 fixed on the outer end of the shaft body 603 to rotate. The fan blade assembly 12 is detachably mounted on the outer end of the shaft body 603 through the mounting sleeve 1201. After the blades 1202 rotate, they will drive the air to flow. Under the guidance of the airflow, the debris will pass through the through hole 604 and move backwards, so as to deal with the generated debris, avoid the debris from staying inside the blind hole 602, and avoid the debris from clogging the through hole 604.

[0032] In order to collect the debris generated during the grinding process, such as Figure 1 , 2 As shown in FIG. 4 , two air guide channels 11 are provided on the base 5 , and the two air guide channels 11 are symmetrically arranged on both sides of the shaft 603 . The air guide channels 11 penetrate the base 5 , and the air driven by the fan blade assembly 12 can flow through the air guide channels 11 .

[0033] A net bag 3 is provided at the rear end exit of the air guide channel 11. A connecting ring 13 is fixedly provided at the open end of the net bag 3. The connecting ring 13 is detachably connected to the rear side of the base 5, and the net bag 3 can filter the grinding debris carried in the air.

[0034] The operation of the fan blade assembly 12 drives the air flow, so that suction is generated at the front end of the air guide channel 11. Under the action of the suction, the debris generated during the grinding process will be sucked into the air guide channel 11 and flow along the air guide channel 11 to the net bag 3. After reaching the net bag 3, the air is discharged to the outside, and the debris carried in the air remains in the net bag 3 for subsequent unified treatment to avoid the debris splashing and being difficult to handle.
