Description

Technical Field

[0001] The invention belongs to an inner side arc surface grooving device for shaft sleeve processing, and in particular relates to the field of shaft sleeve processing. Background Art

[0002] Mechanical workpieces are single parts that are inseparable from machinery and machines. They play an important role in the automation industry. Mechanical workpieces include the connection of parts, supporting parts, lubrication systems and sealing parts for lubrication, and parts of the transmission system that transmit motion and energy. Shaft-type workpieces are the main type of workpieces. Shaft-type workpieces are suitable for one or more CNC machine tools. Shaft-type workpieces are one of the typical workpieces often encountered in hardware accessories. They are mainly used to support transmission parts, transmit torque and bear loads. According to the different structural forms of shaft-type workpieces, shaft-type workpieces can be divided into three categories: smooth shafts, stepped shafts and anisotropic shafts. They can also be divided into solid shafts and hollow shafts. The shaft sleeve workpiece is a main type of shaft-type workpiece. The shaft sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft and is a component of the sliding bearing. In the process of producing and processing the shaft sleeve mechanical workpiece, the shaft sleeve workpiece needs to undergo die-casting, grinding and punching processing in sequence. The shaft sleeve workpiece has various types of sizes and shapes. Especially when grooving the inner arc surface of the shaft sleeve with a hemispherical structure, the existing processing equipment is difficult to meet the needs of shaft sleeve processing. Since the end of the shaft sleeve is a circular structure, the existing clamping mechanism is difficult to clamp and fix the shaft sleeve conveniently and efficiently. The shaft sleeve often falls off during the shaft sleeve processing process due to the lack of firm clamping and fixing. In addition, the existing clamping mechanism is difficult to apply to the clamping and fixing of shaft sleeve workpieces of various sizes and specifications, and has a narrow scope of application. In the process of processing the shaft sleeve, the existing shaft sleeve processing mechanism mainly adopts the method of clamping and fixing the shaft sleeve and adjusting the processing head to the work position as needed to realize the processing of the shaft sleeve.

[0003] However, due to the complex structure of the processing head and the large number of drive mechanisms, it is difficult for the processing head to rotate and translate smoothly according to the needs of the shaft sleeve processing. The existing shaft sleeve processing mechanism is difficult to quickly clamp and fix the shaft sleeve and automatically remove the workpiece after processing. Therefore, in the existing processing of the shaft sleeve workpiece, the processing process is extremely cumbersome, which delays production efficiency and leads to a long processing cycle, which cannot meet the needs of large-scale production of shaft sleeve workpieces. The existing grooving processing mechanism has a complex structure and is cumbersome to operate. It is difficult to smoothly and stably perform grooving on the arc surface, the processing head is troublesome to adjust, and the processing head is difficult to quickly and conveniently move. The present inventors propose an inner arc surface grooving device for shaft sleeve processing that can quickly install and automatically eject workpieces, and can quickly and stably adjust the tool position, so as to improve processing efficiency and processing accuracy.

[0040] In this setting, the sliding push rod 12 slides and pushes the clamping push rod 13 to retract inward, driving the anti-slip pad 15 to clamp and fix the sleeve processing part 5. At this time, the sleeve processing part 5 is released, and the inner end of the rotating push rod 11 is stuck in the slot 17 and cannot be reset.

At this time, the sleeve workpiece 5 is released. Since the inner end of the rotating push rod 11 is stuck in the groove 17 and cannot be reset, during the processing, the cutting fluid is sprayed on the guide cone head 601, and the cutting fluid is rebounded by the conical surface and sprayed to the surroundings to cool the workpiece and the cutter head 611; when the processing is completed, the guide cone head 601 pushes the water pipe 27 to shrink inward, and the water pipe 27 drives the transmission gear 20 to rotate through the tooth groove 19 on its surface, and drives the release push rod 10 to slide through the rack 21, so that the other end of the release push rod 10 pushes the rotating push rod 11 to continue to rotate until the inner end of the rotating push rod 11 is disengaged from the groove 17, causing the rebound ring 16 to rebound and reset, and the sleeve workpiece 5 is pushed out.
