[0001] The invention relates to the technical field of anti-slipping devices, and in particular to an anti-slipping device for a chuck and a connecting rod used in a honing machine. Background Art

[0002] A honing machine is a grinding machine that uses a honing head to hone the workpiece's fine-machined surface. It is mainly used to hone the holes of workpieces in the manufacturing industries of automobiles, tractors, hydraulic parts, bearings, aviation, etc. There are two types of honing machines: vertical and horizontal. The vertical honing machine has a shorter spindle working stroke and is suitable for honing cylinder blocks and box holes. The honing head inlaid with oilstone is driven to rotate by the vertically placed spindle, and at the same time, it performs vertical reciprocating feed motion under the drive of the hydraulic device. The horizontal honing machine has a longer working stroke and is suitable for honing deep holes. The horizontally placed honing head does not rotate, but only performs axial reciprocating motion. The workpiece is driven to rotate by the spindle. A center frame supporting the workpiece and a guide frame supporting the honing rod are provided in the middle of the bed. During the processing, the oilstone of the honing head is radially fed under the action of the expansion and contraction mechanism, and the workpiece is gradually processed to the required size.

[0003] The honing head of the honing machine is directly connected to the main shaft through a chuck and a connecting rod, and then fixed with a jackscrew or a screw to prevent the connecting rod from partially detaching. After the honing machine has been operating for a long time, the jackscrew or the screw used for fixing is easy to loosen, making the connection between the honing head and the main shaft unstable, and there is a greater risk of the honing head falling off.

[0004] Therefore, it is necessary to provide a chuck and connecting rod anti-dropping device for a honing machine to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The embodiments of the present invention include but are not limited to the following embodiments.

[0034] Embodiment 1:

[0035] like Figure 1-11 As shown, the clamping head and connecting rod anti-dropping device for a honing machine provided by the present invention comprises: a clamping head mechanism 3 for connecting the main shaft 1 of the honing machine and the connecting rod 2 of the honing head; the clamping head mechanism 3 comprises a connecting tube 5, one end of the connecting tube 5 is connected to the main shaft 1 of the honing machine, and the other end is connected to the connecting rod 2 of the honing head by a hanging pin. Specifically, two L-shaped clamping grooves 8 are provided in a circular array at the end of the connecting tube 5, and a stop position 9 and an inner entrance 10 are provided on the clamping groove 8. The hanging pin 4 on the end of the connecting rod 2 of the honing head is inserted into the outer opening of the clamping groove 8, and the end of the connecting rod 2 of the honing head is inserted into the connecting tube 5, and then the honing head is axially rotated. The honing head is made to engage with the hanging pin 4 by snapping it into the stop position 9, thereby realizing the hanging pin connection between the connecting tube 5 and the honing head connecting rod 2. A stop ring 7 and an elastic component 6 are sleeved and installed on the connecting tube 5. Two limit heads 11 are arranged on the stop ring 7. Under the stress of the elastic component 6, the stop ring 7 moves the thrust ring 7 toward the slot 8. The limit head 11 is inserted into the slot 8 from the inner entrance 10 and abuts against the side of the hanging pin 4, so that the hanging pin 4 cannot rotate, thereby preventing the hanging pin 4 of the honing head connecting rod 2 from escaping from the slot 8, thereby preventing the axial reversal and falling off of the honing head, so that the honing head connecting rod 2 can be stably connected to the connecting tube 5.

[0036] By setting up a clamping head mechanism 3 including a connecting tube 5, an elastic component 6, a stop ring 7, and a clamping groove 8, after the honing head connecting rod 2 is connected to the connecting tube 5 by a hanging pin, the elastic force of the elastic component 6 can be used to drive the stop ring 7 to move on the connecting tube 5, and the limit head 11 is inserted into the clamping groove 8 to limit the hanging pin 4, thereby preventing the honing head from falling off.

[0037] Embodiment 2:

[0038] like Figure 1-4 As shown, an annular groove 15 is provided on the connecting pipe 5, and a clamping ring 16 is installed in the annular groove 15. One end of the clamping ring 16 abuts against one end of the elastic component 6 to limit the side of the elastic component 6 close to the main shaft.

[0039] By providing an annular groove 15 on the connecting pipe 5 and installing a clamping ring 16 in the annular groove 15 , the side of the elastic component 6 close to the honing machine spindle 1 can be limited.

[0040] Embodiment 3:

[0041] like Figure 1-3 As shown, in this embodiment, the elastic component 6 is a first spring, and the first spring is sleeved and installed on the connecting tube 5, one end of which is fixed, and the other end is against the stop ring 7, and the first spring is always in a compressed state. The compressed first spring drives the limit head 11 at the end of the stop ring 7 to be stuck in the slot 8 and will not withdraw.

[0042] By setting the elastic component 6 as the first spring, the elasticity of the first spring can be conveniently utilized to ensure that the limiting head 11 is inserted into the slot 8 and will not come out.

[0043] Embodiment 4:

[0044] like Figure 10-11 As shown, in this embodiment, the elastic component 6 includes a first mounting ring 20 and a second mounting ring 21, and a plurality of connecting rods 22 are installed between the second mounting ring 21 and the first mounting ring 20. One end of the connecting rod 22 is fixedly connected to the second mounting ring 21, and the other end passes through the first mounting ring 20. The first mounting ring 20 and the second mounting ring 21 are sleeved on the connecting pipe 5, one side of the first mounting ring 20 abuts against the clamping ring 16, and one side of the second mounting ring 21 abuts against the stop ring 7, and a second spring 23 is sleeved and installed on the connecting rod 22, and the second spring 23 is in a compressed state. The compressed second spring 23 drives the second mounting ring 21 away from the first mounting ring 20 and makes the connecting rod 22 move axially, thereby driving the thrust ring 7 to move, so that the limit head 11 is stuck in the slot 8.

[0045] By providing an elastic component 6 including a first mounting ring 20 , a second mounting ring 21 , a connecting rod 22 and a second spring 23 , the second mounting ring 21 is driven away from the first mounting ring 20 by utilizing the elastic force of the plurality of second springs 23 , so that the thrust ring 7 moves on the connecting pipe 5 .

[0046] Embodiment 5:

[0047] like Figure 10-11 As shown, the first mounting ring 20 is composed of two hinged first half rings 24, and the second mounting ring 21 is composed of two hinged second half rings 25. The two first half rings 24 and the two second half rings 25 are both equipped with a plug-in rod 26. When installing, the plug-in rod 26 is pulled out from the hole plugged therein so that it is as shown in FIG. Fig.11 The state shown is opened, so that it can be easily clamped on the connecting pipe 5 from the side, and then the distal ends of the two first half rings 24 and the two second half rings 25 are connected by the plug rod 26, so that it is as shown in FIG. Fig.10 state, thereby completing the installation of the elastic component 6. This method can complete the disassembly and assembly of the elastic component 6 without removing the connecting pipe 5 from the honing machine spindle 1, thereby making it more convenient and quick to use.

[0048] By providing an elastic component 6 that can be opened and closed, the elastic component 6 can be easily installed and removed, making it more convenient to use.

[0049] Embodiment 6:

[0050] like Figure 5-7As shown, a contact surface 12 and an arc-shaped guide head 13 are provided on one side of the limit head 11, wherein the contact surface 12 is the side in contact with the hanging pin 4, and the contact surface 12 is inclined so that the width of the end of the limit head 11 close to the guide head 13 becomes smaller. Therefore, the limit head 11 as a whole is a trapezoid with a narrow outside and a wide inside (the side close to the guide head 13 is narrow, and the side away from the guide head 13 is wide). Therefore, after the limit head 11 is inserted into the slot 8 under the guidance of the guide head 13, its contact surface 12 gradually approaches the hanging pin 4 until it completely resists and presses the hanging pin 4.

[0051] By providing an inclined contact surface 12 and an arc-shaped guide head 13 on the limit head 11 , the limit head 11 can be easily guided into the slot 8 to gradually approach and press the hook pin 4 .

When in use, the limit head 11 presses the hanging pin 4 tightly, and under the action of the elastic component 6, the two become tighter and tighter. It is possible that the limit head 11 cannot be disengaged from the slot 8. At this time, a sharp tool can be inserted into the knocking hole 14 and the tail of the tool can be knocked to move the retaining ring 7, thereby making the limit head 11 disengage from the slot 8.

[0054] By providing the knocking hole 14 on the stop ring 7 , the limiting head 11 can be easily removed from the slot 8 .

[0055] Embodiment 8:

[0056] like Fig. 9 As shown, the clamping ring 16 includes an unclosed clamping ring 18, and two connecting ear holes 19 are provided on the clamping ring 18. When in use, a special tool is used to insert the two connecting ear holes 19 respectively, and expand outward to make the clamping ring 18 open and deform, so as to facilitate the clamping ring 18 to be inserted into the annular groove 15, and then the clamping ring 16 is restored under the action of its own stress to complete the installation.

[0057] By providing the clamping ring 16 including the clamping ring 18 and the connecting ear hole 19 , the installation and removal of the clamping ring 16 can be facilitated.

[0058] Embodiment 9:

[0059] like Figure 1-4 As shown, two connecting parts 17 are provided on the connecting pipe 5 , and the connecting parts 17 are connected to the honing machine spindle 1 through pins or bolts, thereby connecting the connecting pipe 5 to the honing machine spindle 1 .

[0060] By providing two connection parts 17 on the connection pipe 5 , the connection between the connection pipe 5 and the honing machine spindle 1 can be facilitated.

[0061] Working principle: When in use, the hanging pin 4 on the end of the honing head connecting rod 2 is aligned with the outer opening of the slot 8 and inserted, the end of the honing head connecting rod 2 is inserted into the connecting tube 5, and then the honing head is axially rotated to make the hanging pin 4 snap into the stop position 9. Under the stress of the elastic member 6, the thrust ring 7 moves toward the slot 8, and the inner entrance 10 of the limit head 11 is inserted into the slot 8 and abuts against the side of the hanging pin 4, so that the hanging pin 4 cannot rotate, thereby preventing the hanging pin 4 of the honing head connecting rod 2 from falling out of the slot 8, thereby preventing the axial reversal and falling off of the honing head, so that the honing head connecting rod 2 can be stably connected to the connecting tube 5.
