Description

Technical Field

[0001] The utility model relates to the technical field of multi-jaw chucks, in particular to an inner gasket flange of a multi-jaw chuck. Background Art

[0002] Graphite packing rings are a type of seal. Some graphite packing rings have metal discs inside to enhance the strength of the graphite packing rings. In order to achieve a better combination of the metal disc and graphite, grooves are machined on the metal disc. During the grooving process, a six-jaw chuck is used to clamp the metal disc. However, in actual applications, it is found that since the metal disc itself is relatively thin, it is easy to deform during the grooving process if the metal disc is clamped only by a six-jaw chuck. The deformed metal disc may even fly out of the six-jaw chuck. Therefore, a suitable technical solution is needed to solve the above problems. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides an inner pad flange of a multi-jaw chuck, wherein the flange body is padded in the jaw gap of the multi-jaw chuck, so that the sheet clamped in the multi-jaw chuck is not easily deformed during processing.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides an inner pad flange of a multi-jaw chuck, comprising a multi-jaw chuck and a flange body. The multi-jaw chuck comprises a base and a plurality of jaws. There are a plurality of radial slots on the flange body. The flange body is fixedly connected to one side of the base where the jaws are provided. The plurality of slots are respectively buckled on each jaw, so that each jaw can open and close along each slot. There is an inner pad plane on the disk surface of the flange body on the side facing away from the base. The inner pad plane is perpendicular to the central axis of the multi-jaw chuck, and the front end of the jaw extends from the slot to the inner pad plane, so that the front end of each jaw can cooperate for grasping.

[0005] Furthermore, the claws are separated from the inner wall of the slots by a gap, and a plurality of radial slots are connected at the center of the flange body.

[0006] Furthermore, a pick-up slot is provided on a side of the flange body facing away from the base; when the sheet to be processed is clamped between the claws, the outer edge of the sheet half covers the pick-up slot.

[0007] Furthermore, a slider is provided on the disk surface of the flange body facing away from the base, and one side surface of the slider is flush with the inner pad plane; a picking slot is correspondingly opened on the slider, and the slider can slide on the flange body to change the position of the picking slot.

[0008] Furthermore, a guide rail groove is provided on the disk surface on one side of the flange body facing away from the base, and the slider is slidably matched with the guide rail groove; a screw hole is provided in the slider, and a rotatable adjusting screw is provided in the flange body, and the adjusting screw is threadably matched with the screw hole. When the adjusting screw rotates, it drives the slider to slide along the guide rail groove.

[0009] Furthermore, the extending direction of the guide rail groove is the radial direction of the flange body.

[0010] Beneficial effects: The inner flange of the multi-jaw chuck of the utility model has the following beneficial effects:

[0011] 1) Place the flange body in the gap between the jaws of the multi-jaw chuck. When the multi-jaw chuck clamps the sheet, one side of the sheet fits against the flange body. Under the support of the flange body, the sheet is not easily deformed during processing, so that the multi-jaw chuck can stably clamp the sheet.

[0012] 2) A picking groove is provided on the flange body, and the picking groove can slide to the edge of the sheet body along with the slider. After the multi-claw chuck releases the sheet body, the sheet body that is closely attached to the flange body can be removed through the picking groove. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Attached Figure 1 Schematic diagram of the flange body installed on the multi-jaw chuck. DETAILED DESCRIPTION

[0014] The utility model is further described below in conjunction with the accompanying drawings.

[0015] As attached Figure 1 The inner flange of a multi-jaw chuck comprises a multi-jaw chuck 1 and a flange body 2. The multi-jaw chuck 1 comprises a base 3 and a plurality of jaws 4. The plurality of jaws 4 can be opened and closed on the base 3 to clamp an object. The flange body 2 has a plurality of radial slots 5, and the number of the slots 5 is the same as the number of the jaws 4 on the multi-jaw chuck 1. The flange body 2 is fixedly connected to one side of the base 3 where the jaws 4 are provided. Figure 1 As shown in the figure, the flange body 2 is fixed to the base 3 by multiple fixing bolts 11, that is, a threaded groove is opened on the base 3, and a through hole is opened on the flange body 2. The fixing bolts 11 pass through the through hole and are tightened in the threaded groove to fix the flange body 2 on the base 3.

[0016] When the flange body 2 is fixed on the base 3, the multiple slots 5 are buckled on each claw 4, so that each claw 4 can open and close along each slot 5. There is an inner pad plane 6 on the side of the flange body 2 facing away from the base 3. The inner pad plane 6 is perpendicular to the central axis of the multi-claw chuck 1, and the front end of the claw 4 extends from the slot to the inner pad plane 6, so that the front end of each claw 4 can cooperate to grasp. When it is necessary to clamp the sheet body by the multi-claw chuck 1, due to the existence of the flange body 2, the inner pad plane 6 of the flange body 2 can support one side surface of the sheet body, so that the sheet body is not easily deformed during processing. For example, when the metal disc in the graphite packing ring is being grooved, the multi-claw chuck 1 with the flange body 2 installed can be used to clamp and fix the metal disc.

[0017] The claws 4 are separated from the inner wall of the slots 5 by a gap, that is, the width of the slots 5 is slightly larger than the width of the claws 4, so that the inner pad plane 6 on the flange body 2 has a larger area and a better support effect on the sheet. The radially arranged slots 5 are connected at the center of the flange body 2, so that the claws 4 can be gripped together.

[0018] The flange body 2 is provided with a take-out groove 7 on the side of the disk facing away from the base 3. When the sheet to be processed is clamped between the claws 4, the outer edge of the sheet half covers the take-out groove 7. When processing the sheet, the sheet will be tightly attached to the inner pad plane 6 of the flange body 2. After the processing is completed, even if the claws 4 release the sheet, the sheet may still be attached to the inner pad plane 6 of the flange body 2. After the claws 4 release the sheet, the gap between the claws 4 and the sheet is not large, and it is not convenient to grab the edge of the sheet from the gap between the claws 4 and the sheet. Therefore, the take-out groove 7 is provided, and the edge of the sheet is directly grabbed from the take-out groove 7, and then the sheet is taken out.

[0019] In practical applications, depending on the shape of the claws 4, the disk surface of the flange body 2 facing away from the base 3 may be a whole circular plane or may be a plurality of annular planes arranged in a stepped manner.

[0020] As attached Figure 1 As shown in , when the disk surface of the flange body 2 facing away from the base 3 is a whole circular plane, a slider 8 is provided on the disk surface of the flange body 2 facing away from the base 3, and one side surface of the slider 8 is flush with the inner pad plane 6, so that the slider 8 can also support the sheet. The extraction groove 7 is correspondingly opened on the slider 8, and the slider 8 can slide on the flange body 2 to change the position of the extraction groove 7. Since the extraction groove 7 is opened on the slider 8, and one side surface of the slider 8 can support the sheet, the supported area of ​​the sheet can be increased, and the sheet is less likely to deform.

[0021] In one embodiment, a guide groove 9 is provided on the side of the flange body 2 facing away from the base 3, and the slider 8 is slidably matched with the guide groove 9, and the slider 8 is clamped in the guide groove 9, so that the slider 8 will not fall out of the guide groove 9 when sliding along the guide groove 9. A screw hole is provided in the slider 8, and a rotatable adjusting screw 10 is provided in the flange body 2. A rotating hole is provided on the flange body 2, and the adjusting screw 10 is rotatably matched with the rotating hole, and the rotating hole limits the axial position of the adjusting screw 10. When the adjusting screw 10 rotates, the position of the adjusting screw 10 on the flange body 2 remains unchanged, and the adjusting screw 10 is threadedly matched with the screw hole. Therefore, when the adjusting screw 10 rotates, the adjusting screw 10 can drive the slider 8 to slide along the guide groove 9, thereby adjusting the position of the picking slot 7 to adapt to sheets of different sizes, so that the picking slot 7 is just located at the edge of the sheet. The extension direction of the guide groove 9 is the radial direction of the flange body 2.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
