Description

Technical Field

[0001] The utility model relates to the technical field of processing of fire hydrant socket machines, and particularly relates to a clamping and positioning mechanism for processing fire hydrant socket machines. Background Technique

[0002] A fire hydrant is a fixed fire-fighting facility, and its main functions are to control combustibles, isolate combustion-supporting substances, and eliminate ignition sources. A fire hydrant socket machine is one of the components of a fire hydrant.

[0003] When processing a fire hydrant socket machine, it needs to be clamped. However, general clamping mechanisms are difficult to quickly clamp and position the fire hydrant socket machine, which easily causes it to loosen during the processing, affecting the processing accuracy, and it is also difficult to adapt to fire hydrant socket machines of different sizes. Therefore, we propose a clamping and positioning mechanism for processing fire hydrant socket machines. Content of the Utility Model

[0004] The purpose of the utility model is to provide a clamping and positioning mechanism for processing fire hydrant socket machines to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A clamping and positioning mechanism for processing fire hydrant socket machines includes a base, a clamping seat, clamping arms, arc-shaped clamping blocks, and a positioning support. The clamping seat is installed at the top end of the base through a bearing, and a second bidirectional lead screw is installed inside the clamping seat. Sliders are threadedly connected to the outer walls on both sides of the second bidirectional lead screw. A second rotation driving member is installed at one end of the clamping seat, and the output end of the second rotation driving member is fixedly connected to the second bidirectional lead screw. The clamping arms are all arranged above the clamping seat, and the bottom ends of the clamping arms are fixedly connected to the sliders. A first bidirectional lead screw is installed inside the clamping arms, and a first rotation driving member is installed at the top end of the clamping arms. The output end of the first rotation driving member is fixedly connected to the first bidirectional lead screw. The arc-shaped clamping blocks are all sleeved on the outer wall of the first bidirectional lead screw, and the arc-shaped clamping blocks are threadedly connected to the first bidirectional lead screw. A socket machine body is arranged above the clamping seat between the clamping arms. The positioning support is fixed at the center position of the top end of the clamping seat, and telescopic driving members are installed on both sides inside the positioning support. The output ends of the telescopic driving members extend into the positioning support and are fixedly connected with positioning blocks.

[0006] Preferably, a third rotation driving member is installed inside the base, and the output end of the third rotation driving member is fixedly connected to the clamping seat, which is convenient for driving the clamping seat to rotate so as to change the orientation of the socket machine body.

[0007] Preferably, rubber friction sheets are adhered to the inner walls of the arc-shaped clamping blocks, which not only plays a role in increasing the friction force but also can prevent the surface of the socket machine body from being worn.

[0008] Preferably, the bottom end of the clamping arm is communicated with the slider through an oil drain hole, facilitating the lubricating oil to flow into the slider to lubricate the second bidirectional lead screw.

[0009] Preferably, an oil box is installed on one side of the top end of the clamping arm, and an oil outlet hole is provided at the bottom end of the oil box, facilitating the storage of lubricating oil.

[0010] Preferably, a drip oil pipe is installed at the bottom end of the oil outlet hole, and one end of the drip oil pipe extends into the clamping arm, facilitating the dripping of lubricating oil.

[0011] Preferably, a pull rod is arranged inside the oil box, and a sealing plug is fixed at the bottom end of the pull rod. The sealing plug is tightly clamped with the oil outlet hole, and the top end of the pull rod extends above the oil box, facilitating the control of the communication state of the oil outlet hole.

[0012] Preferably, a spring is installed on the outer wall of the top of the pull rod, and the bottom end of the spring is fixedly connected with the oil box.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1) Place the card seat machine body between the clamping arms, start the first rotation driving member and the second rotation driving member. The second rotation driving member drives the second bidirectional lead screw to rotate, so that the slider drives the clamping arms to translate synchronously towards the card seat machine body in the left-right direction. At the same time, the first rotation driving member drives the first bidirectional lead screw to rotate, so that the arc-shaped clamping blocks translate synchronously towards the card seat machine body in the up-down direction until the arc-shaped clamping blocks clamp the card seat machine body. Then, start the telescopic driving member inside the positioning support to drive the positioning block to translate, and the positioning block abuts against the inner walls of the flanges on both sides of the card seat machine body, playing a role in positioning the card seat machine body, thereby quickly clamping and positioning the card seat machine, preventing it from loosening during the processing, and further improving the processing accuracy. Since the left-right distance between the clamping arms and the up-down distance between the arc-shaped clamping blocks are both adjustable, the clamping and positioning requirements of card seat machine bodies with different sizes can be met;

[0015] (2) Pull up the pull rod to make the sealing plug disengage from the oil outlet hole, and the oil outlet hole is opened, so that the lubricating oil in the oil box drips out through the drip oil pipe to lubricate the first bidirectional lead screw inside the clamping arm. Then release the pull rod to make it return to its original position under the elastic action of the spring. The pull rod drives the sealing plug to plug into the oil outlet hole to seal it. The excess lubricating oil on the surface of the first bidirectional lead screw flows into the slider through the oil drain hole to lubricate the second bidirectional lead screw. This design realizes the self-lubrication function, prevents the mechanism from getting stuck and worn during operation, and prolongs the service life of the mechanism.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , an embodiment provided by the present utility model: a clamping and positioning mechanism for processing a fire hydrant card seat machine, including a base 1, a clamping seat 2, a clamping arm 3, an arc-shaped clamping block 5 and a positioning support 20. The clamping seat 2 is installed at the top of the base 1 through a bearing, and a second bidirectional lead screw 9 is installed inside the clamping seat 2. Sliders 8 are threadedly connected to the outer walls on both sides of the second bidirectional lead screw 9. A second rotary driving member 10 is installed at one end of the clamping seat 2, and the output end of the second rotary driving member 10 is fixedly connected to the second bidirectional lead screw 9;

[0024] The clamping arms 3 are all arranged above the clamping seat 2. The bottom end of the clamping arm 3 is fixedly connected to the slider 8. A first bidirectional lead screw 4 is installed inside the clamping arm 3. A first rotary driving member 6 is installed at the top end of the clamping arm 3. The output end of the first rotary driving member 6 is fixedly connected to the first bidirectional lead screw 4. The arc-shaped clamping blocks 5 are all sleeved on the outer wall of the first bidirectional lead screw 4, and the arc-shaped clamping blocks 5 are threadedly connected to the first bidirectional lead screw 4;

[0025] Above the clamping seat 2 between the clamping arms 3, a card seat machine body 7 is provided. The positioning support 20 is fixed at the center position of the top end of the clamping seat 2, and telescopic driving members 21 are installed on both sides inside the positioning support 20. The output ends of the telescopic driving members 21 extend into the positioning support 20 and are fixed with positioning blocks 22;

[0026] Specifically, place the card seat machine body 7 between the clamping arms 3, start the first rotary driving member 6 and the second rotary driving member 10. The second rotary driving member 10 drives the second bidirectional lead screw 9 to rotate, so that the slider 8 drives the clamping arms 3 to translate synchronously from the left and right directions towards the card seat machine body 7. At the same time, the first rotary driving member 6 drives the first bidirectional lead screw 4 to rotate, so that the arc-shaped clamping blocks 5 translate synchronously from the up and down directions towards the card seat machine body 7 until the arc-shaped clamping blocks 5 clamp the card seat machine body 7;

[0027] Start the telescopic driving member 21 inside the positioning support 20 to drive the positioning block 22 to translate. The positioning block 22 abuts against the flange inner walls on both sides of the card seat machine body 7, playing a role in positioning the card seat machine body 7, so that the card seat machine can be quickly clamped and positioned, preventing it from loosening during the processing, and thus improving the processing accuracy;

[0028] A third rotary driving member 11 is installed inside the base 1, and the output end of the third rotary driving member 11 is fixedly connected to the clamping seat 2;

[0029] A rubber friction plate 13 is adhered to the inner wall of the arc-shaped clamping block 5;

[0030] The bottom end of the clamping arm 3 is communicated with the slider 8 through an oil drain hole 12;

[0031] On one side of the top end of the clamping arm 3, an oil box 14 is installed, and an oil outlet hole 18 is provided at the bottom end of the oil box 14;

[0032] At the bottom end of the oil outlet hole 18, a drip oil pipe 19 is installed, and one end of the drip oil pipe 19 extends into the clamping arm 3;

[0033] A pull rod 15 is arranged inside the oil box 14, and a sealing plug 17 is fixed at the bottom end of the pull rod 15. The sealing plug 17 is tightly clamped with the oil outlet hole 18, and the top end of the pull rod 15 extends above the oil box 14;

[0034] A spring 16 is installed on the outer wall of the top of the pull rod 15, and the bottom end of the spring 16 is fixedly connected to the oil box 14;

[0035] Specifically, after using for a period of time, pull the pull rod 15 upward to make the sealing plug 17 disengage from the oil outlet hole 18, and the oil outlet hole 18 is opened, so that the lubricating oil in the oil box 14 drips out through the drip oil pipe 19 to lubricate the first bidirectional lead screw 4 inside the clamping arm 3. Then release the pull rod 15 to make it return to its original position under the elastic action of the spring 16. The pull rod 15 drives the sealing plug 17 to plug into the oil outlet hole 18 to seal it. The excess lubricating oil on the surface of the first bidirectional lead screw 4 flows into the slider 8 through the oil drain hole 12 to lubricate the second bidirectional lead screw 9. This design realizes the self-lubrication function, prevents the mechanism from jamming and wearing during operation, and prolongs the service life of the mechanism.

[0036] When the embodiment of the present application is in use: First, place the card seat machine body 7 between the clamping arms 3, and start the first rotation driving member 6 and the second rotation driving member 10 by operating the external control panel. The second rotation driving member 10 drives the second bidirectional lead screw 9 to rotate, so that the slider 8 drives the clamping arms 3 to translate synchronously from the left and right directions towards the card seat machine body 7. At the same time, the first rotation driving member 6 drives the first bidirectional lead screw 4 to rotate, so that the arc-shaped clamping block 5 translates synchronously from the up and down directions towards the card seat machine body 7 until the arc-shaped clamping block 5 clamps the card seat machine body 7. Then, start the telescopic driving member 21 inside the positioning support 20 to drive the positioning block 22 to translate. The positioning block 22 abuts against the inner wall of the flange on both sides of the card seat machine body 7, playing a role in positioning the card seat machine body 7, so that the card seat machine can be quickly clamped and positioned, preventing it from loosening during the processing, thereby improving the processing accuracy. Moreover, the setting of the rubber friction plate 13 not only plays a role in increasing the friction force, but also can prevent the surface of the card seat machine body 7 from being worn. Since the left and right spacing of the clamping arms 3 and the up and down spacing of the arc-shaped clamping block 5 are adjustable, the clamping and positioning requirements of card seat machine bodies 7 of different sizes can be met. Then, after using for a period of time, pull the pull rod 15 upward to make the sealing plug 17 disengage from the oil outlet hole 18, and the oil outlet hole 18 is opened, so that the lubricating oil in the oil box 14 drips out through the drip oil pipe 19 to lubricate the first bidirectional lead screw 4 inside the clamping arm 3. Then release the pull rod 15 to make it return to its original position under the elastic action of the spring 16. The pull rod 15 drives the sealing plug 17 to plug into the oil outlet hole 18 to seal it. The excess lubricating oil on the surface of the first bidirectional lead screw 4 flows into the slider 8 through the oil drain hole 12 to lubricate the second bidirectional lead screw 9. This design realizes the self-lubrication function, prevents the mechanism from jamming and wearing during operation, and prolongs the service life of the mechanism.
