Description

Technical Field

[0001] The utility model relates to the technical field of groove rolling processing, and more specifically to a clamping mechanism of a groove rolling machine. Background Art

[0002] The groove rolling machine is a mechanical equipment used to process metal pipes or bars. It is mainly used to roll out threads or grooves on the surface of the pipe. The clamping mechanism is an important part of the groove rolling machine, which is used to clamp and fix the pipe to be processed.

[0003] The prior art discloses a clamping mechanism of a grooving machine, which is a utility model patent with application number CN202322705959.2. The clamping mechanism increases the supporting force on the pipe by utilizing a plurality of pressing blocks to abut against the inner wall of the pipe, so that the pipe is not easily offset when grooving the pipe, thereby improving the grooving accuracy of the grooving machine on the pipe and reducing unnecessary material waste.

[0004] When in use, it is necessary to insert the pipe into the fixed column and then rotate and move the pressure block to fix the pipe. Although the labor intensity of workers is reduced by setting a rotating disk, the method of inserting the pipe into the fixed column and then rotating the rotating disk is relatively time-consuming and affects efficiency if a large number of pipes need to be processed. Utility Model Content

This process does not require special operation and is simple and convenient with high fixing efficiency. After the grooving is completed, the fixing effect of the fixing part on the pipe can be canceled by simply rotating the pipe.

[0007] Preferably, a plurality of evenly arranged fixing plates are fixedly connected to the inner wall of the storage bin, and the fixing plates are penetrated by the limiting ring and fixedly connected thereto, a spring is fixedly connected to the outer wall of the fixing plate, and the spring sleeves the limiting ring therein, and the other end of the spring abuts against the outer wall of the limiting block; through the elastic force of the spring, after the grooving of the pipe is completed and the grooving roller stops, the spring rebounds so that the fixing part automatically releases the fixing effect on the pipe, without the need for the user to rotate the pipe, thereby increasing the convenience of taking out the pipe after the grooving of the pipe is completed, thereby reducing the labor intensity of the user and increasing the efficiency of the pipe grooving.

[0008] Preferably, a rubber ring is provided at one end of the fixing member away from the limit block; by providing the rubber ring, the pipe is fixed by the rubber ring directly contacting the pipe, and the rubber ring can fit with the inner wall of the pipe over a larger area due to its own elasticity, thereby increasing the fixing effect of the pipe.

[0009] Preferably, one end of the fixing member away from the limiting block is fixedly connected to a ratchet, and the rubber ring is sleeved on the outer ring of the ratchet; the provision of the ratchet can prevent the rubber wheel from reversing, which may reduce the fixing effect on the pipe.

[0010] Preferably, the outer wall of the fixing member is rotatably connected with an anti-carding sleeve, and the outer wall of the anti-carding sleeve can fit with the inner wall of the inclined part of the slot under the support of the fixing member; by arranging the anti-carding sleeve, the fixing member is not in direct contact with the slot, reducing the probability of wear and jamming between the two.

[0011] Preferably, the rubber ring is gradually tilted upward from one side close to the fixing member to the other side; the tilted rubber ring can reduce the probability of getting stuck between the rubber ring and the pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model inserts one end of the pipe to be grooved directly into the grooving roller, and grooves the pipe by driving the grooving roller and the pressure roller to rotate through the grooving machine body. In this process, the fixing part can be automatically lifted up to fix the pipes with different inner diameters under the action of the rotating force of the grooving roller and the friction between the fixing part and the inner wall of the pipe. The process does not require special operation, is simple and convenient, and has high fixing efficiency.

[0014] 2. The utility model uses the elastic force of the spring. After the pipe grooving is completed and the grooving roller stops, the spring rebounds so that the fixing part automatically releases the fixing effect on the pipe, thereby increasing the convenience of taking out the pipe after the pipe grooving is completed, thereby reducing the labor intensity of the users and increasing the efficiency of the pipe grooving.

[0022] like Figures 1 to 5As shown, the utility model relates to a clamping mechanism of a groove rolling machine, comprising a groove rolling machine body 1 and a pressure roller 2 and a groove rolling roller 3 arranged at the ends thereof, a storage bin 4 is provided inside the groove rolling roller 3, a limiting ring 5 is provided inside the storage bin 4, an outer ring of the limiting ring 5 is evenly slidably connected to a limiting block 6, an outer wall of the limiting block 6 is hinged with a fixing member 7 through a torsion spring, an outer wall of the groove rolling roller 3 is evenly provided with a movable groove 8 connected with the inside of the storage bin 4, one end of the fixing member 7 passes through the movable groove 8 to the outside of the groove rolling roller 3, and a plurality of card slots are evenly provided on the inner wall of the movable groove 8 9. The inner wall of the card groove 9 is inclined; by directly inserting one end of the pipe to be grooved into the groove rolling roller 3, the groove rolling roller 3 and the pressure roller 2 are driven by the groove rolling machine body 1 to rotate to groove the pipe, and in this process, the fixing part 7 can be automatically lifted up to fix the pipes with different inner diameters under the action of the rotating force of the groove rolling roller 3 and the friction force generated between the fixing part 7 and the inner wall of the pipe. This process does not require special operation and is simple and convenient with high fixing efficiency. After the grooving is completed, the fixing effect of the fixing part 7 on the pipe can be canceled by simply rotating the pipe.

[0023] Furthermore, a plurality of evenly arranged fixing plates 10 are fixedly connected to the inner wall of the storage bin 4, and the fixing plates 10 are penetrated by the limiting ring 5 and fixedly connected thereto, a spring 11 is fixedly connected to the outer wall of the fixing plate 10, and the spring 11 sleeves the limiting ring 5 therein, and the other end of the spring 11 abuts against the outer wall of the limiting block 6; through the elastic force of the spring 11, after the grooving of the pipe is completed and the grooving roller 3 stops, the spring 11 rebounds so that the fixing part 7 automatically releases the fixing effect on the pipe, and the user does not need to rotate the pipe, thereby increasing the convenience of taking out the pipe after the grooving of the pipe is completed, thereby reducing the labor intensity of the user and increasing the efficiency of the pipe grooving.

[0024] Furthermore, a rubber ring 12 is provided at one end of the fixing member 7 away from the limit block 6; by providing the rubber ring 12, the rubber ring 12 directly contacts the pipe to fix the pipe, and the rubber ring 12 can fit with the inner wall of the pipe over a larger area due to its own elasticity, thereby increasing the fixing effect on the pipe.

[0025] Furthermore, one end of the fixing member 7 away from the limiting block 6 is fixedly connected to a ratchet 13, and the rubber ring 12 is sleeved on the outer ring of the ratchet 13; the setting of the ratchet 13 can prevent the rubber wheel from reversing and thus reducing the fixing effect on the pipe.

[0026] Furthermore, the outer wall of the fixing member 7 is rotatably connected with an anti-stuck sleeve 14, and the outer wall of the anti-stuck sleeve 14 can fit with the inner wall of the inclined part of the slot 9 under the support of the fixing member 7; by providing the anti-stuck sleeve 14, the fixing member 7 is not in direct contact with the slot 9, reducing the probability of wear and jamming between the two.

[0027] Furthermore, the side of the rubber ring 12 close to the fixing member 7 gradually tilts upward toward the other side; the tilted rubber ring 12 can reduce the probability of getting stuck between the rubber ring 12 and the pipe.

[0028] Working principle: This embodiment provides a clamping mechanism frame of a groove rolling machine. When in use, one end of the pipe to be grooved is directly inserted into the groove rolling roller 3. When the pipe is inserted into the groove rolling roller 3, the inner wall of the pipe will push the outer wall of the fixing member 7, so that the fixing member 7 begins to twist, and as the pipe is gradually inserted into the groove rolling roller 3, the rubber ring 12 on the fixing member 7 will gradually fit with the inner wall of the pipe, and then the groove rolling roller 3 and the pressure roller 2 are driven to rotate through the groove rolling machine body 1 to roll the groove on the pipe. When the groove rolling roller 3 rotates, the limiting ring 5 is driven to rotate through the fixing plate 10. When the limiting ring 5 rotates, because the rubber ring 12 on the fixing member 7 fits with the inner wall of the pipe, The wall is fitted, so there is friction, and at this time, as the limit ring 5 rotates, the fixing piece 7 and the limit block 6 will not move, but the groove 9 on the groove roller 3 will rotate with the groove roller 3, so that the fixing piece 7 enters the groove 9, and the inclined inner wall of the groove 9 will push the fixing piece 7, so that the fixing piece 7 is twisted toward the inner wall of the pipe, so that it is tightly pressed against the pipe through the rubber ring 12 to fix it, and due to the rotation of the groove roller 3, the fixing piece 7 is tightly pressed against the pipe through the rubber ring 12, and the fixing piece 7 cannot be twisted. At this time, the rotation of the groove roller 3 will drive the pipe to rotate through the fixing piece 7, so that the pressure roller 2 and the groove roller 3 cooperate to groove the pipe;

[0029] After the processing is completed, it should be noted that the rubber ring 12 is connected to the fixing piece 7 through the ratchet 13, and the ratchet 13 is a one-way transmission, so when the rubber ring 12 is pressed against the inner wall of the pipe and drives the pipe to rotate, the rubber ring 12 cannot rotate, thereby ensuring the stability of the pipe when it is fixed. After the groove roller 3 stops rotating, the rubber ring 12 can start to rotate under the action of the spring 11 pushing the limit block 6 and the limit block 6 pushing the fixing piece 7, so that the rubber ring 12 rotates to reduce the force between it and the inner wall of the pipe to fix the pipe, so that the pipe can be removed at this time.

A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
