DETAILED DESCRIPTION

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0020] Reference Figure 1-3 As shown, a finger-preventing pipe clamping mechanism includes a desktop panel 1 and a mounting base 2 which is hollow inside and detachably fixed to one side of the bottom surface of the desktop panel 1 by bolts. One end of the mounting base 2 protrudes from the desktop panel 1. A self-weight-dropping type clamping piece for clamping the pipe is provided on the mounting base 2. A power piece that cooperates with the self-weight-dropping type clamping piece is provided on the other side of the bottom surface of the desktop panel 1. A measuring piece for detecting the fixing effect of the self-weight-dropping type clamping piece on the pipe is provided on one side wall of the mounting base 2.

[0021] By setting up the self-weight falling type clamping parts, measuring parts and power parts, after the pipe fittings are placed, the gravity of the self-weight falling type clamping parts is used to quickly pre-clamp the pipe fittings, and the measuring parts detect whether there are foreign objects after the self-weight falling type clamping parts clamp the pipe. If there are abnormalities, it is determined that there are foreign objects or the operator's fingers are clamped, and then the power parts are opened to open the self-weight falling type clamping parts to facilitate the removal of foreign objects. The pressure brought by the self-weight falling type clamping parts to foreign objects is also relatively small to avoid squeezing the operator's fingers, thereby realizing the anti-finger pinching function. If there are no abnormalities, it is determined that there are no foreign objects or the operator's fingers are clamped, and the power parts are opened again to act on the self-weight falling type clamping parts to improve the clamping effect on the pipe fittings, and further clamp the pipe fittings.

[0022] Specifically, refer to Figure 1-3 As shown, it is worth noting that the deadweight falling type clamping member includes a slide rail 4 vertically slidably arranged on the inner side of the protruding end of the mounting seat 2, and a clamping arm 5 is installed on the top of the slide rail 4. A clamping head corresponding to the clamping arm 5 is fixed on the end surface of the mounting seat 2, and a clamping block 6 is installed on the corresponding side of the clamping head and the clamping arm 5. The corresponding side of the two clamping blocks 6 is provided with a pipe clamping groove;

[0023] The measuring component includes a KTR self-resetting sensor 12 vertically mounted on a side wall of the mounting base 2. The end of the self-resetting telescopic rod of the KTR self-resetting sensor 12 is sleeved with a connecting column 13, and the connecting column 13 is vertically fixed to the bottom end of the slide rail 4;

[0024] The power part includes a cylinder 7 provided at the bottom of the table top 1, a push-pull sleeve 8 threadedly mounted on the telescopic end of the cylinder 7, and a first hinged seat 10 fixed to the bottom end of the slide rail 4. A swinging member 9 is also hingedly connected to the inner side of the mounting seat 2. The bottom of the inner side of the swinging member 9 is hingedly connected to the push-pull sleeve 8, and a connecting rod 11 is hingedly connected between the upper inner side of the swinging member 9 and the first hinged seat 10.

[0025] When processing pipe fittings, the pipe fitting to be processed is placed in the pipe clamping groove of the lower clamping block 6 in advance, and then the cylinder 7 is closed. At this time, no air is taken into the cylinder 7, and then the upper clamping arm 5 and the clamping block 6 as a whole fall rapidly under the gravity of the slide rail 4, close to the lower clamping block 6 and the chuck as a whole. In this way, the two sets of clamping blocks 6 cooperate to achieve the pre-clamping effect of the pipe fitting;

[0026] During this process, the falling slide rail 4 synchronously stretches the self-resetting telescopic rod of the KTR self-resetting sensor 12, causing it to continue to extend downward, and the first hinge seat 10 synchronously moves down the slide rail 4, and the connecting rod 11 pulls the swing member 9 to deflect to one side, causing the push-pull sleeve 8 to be pulled by the tension and stretch the telescopic rod of the cylinder 7 to extend outward;

[0027] After pre-clamping, the KTR self-reset sensor 12 sets the stretching length of the self-reset telescopic rod. If the stretching length is greater than the set value, it is determined that there is a foreign object or the operator's finger between the two clamping blocks 6, so the cylinder 7 is opened and air is ventilated into the cylinder 7. The telescopic rod of the cylinder 7 pulls the push-pull sleeve 8 to contract, causing the swing member 9 to deflect to one side and the first hinge seat 10 to be pulled up by the connecting rod 11, so that the slide rail 4 carries the upper clamping pressure arm 5 and the clamping block 6 to slide up quickly, thereby opening the two clamping blocks 6, making it convenient to remove foreign objects and realize the anti-pinch finger function;

[0028] On the contrary, if the stretching length is less than the set value, it is determined that there is no foreign object or operator's finger between the two clamping blocks 6, so the cylinder 7 is turned on, causing the telescopic rod of the cylinder 7 to extend outward, further pressing down the slide rail 4, and strengthening the clamping effect of the two clamping blocks 6 on the pipe fitting;

[0029] After the clamped pipe is processed, the cylinder 7 is further opened in the same way, so that the telescopic rod of the cylinder 7 is contracted, causing the slide rail 4 to carry the upper clamping pressure arm 5 and the clamping block 6 to slide up quickly, and then the two clamping blocks 6 are opened to facilitate manual replacement of the pipe. Then the cylinder 7 is closed again so that no air is taken in, and the slide rail 4 slides down again under gravity to pre-clamp the pipe.

[0030] Further, refer to Figure 3 As shown, it is worth noting that the power member also includes a second hinged seat 16 installed on the end of the cylinder 7 away from the push-pull sleeve 8, and an hinged arm 15 is hinged on the inner side of the second hinged seat 16. A connecting seat 14 is fixed between the top end of the hinged arm 15 and the bottom surface of the desktop panel 1;

[0031] During the extension and retraction of the telescopic rod of the cylinder 7, while the swing member 9 is pushed and pulled and deflected, the cylinder 7 can still deflect synchronously under the hinged action of the second hinge seat 16 and the hinge arm 15, so that the swing member 9 can rotate freely and avoid jamming.

[0032] Further, refer to Figure 3 As shown, it is worth noting that a movable plate 17 is tightly sleeved on the rod of the push-pull sleeve 8, and both ends of the movable plate 17 slide through a guide rod 18 fixedly connected to the cylinder 7, and a compression spring 19 is sleeved on the rod of the guide rod 18, and the two ends of the compression spring 19 are fixedly connected to the movable plate 17 and the cylinder 7 respectively;

[0033] By setting the movable plate 17, guide rod 18 and compression spring 19, when the cylinder 7 is opened to retract its telescopic rod, the push-pull sleeve 8 can synchronously carry the movable plate 17 on the rod body of the guide rod 18 to slide toward the cylinder 7, thereby compressing the compression spring 19 to deform. In this way, by utilizing the elastic force of the compression spring 19, when the cylinder 7 is closed and no air is taken in, the slide rail 4 falls under its own gravity, and the compression spring 19 rebounds the movable plate 17, accelerating the extension rate of the telescopic rod of the cylinder 7, and then, as shown above, synchronously and quickly pulls down the first hinged seat 10, increases the descending rate of the slide rail 4, and makes the two sets of clamps 6 quickly merge and pre-clamp.

[0034] Further, refer to Figure 1-3 As shown, it is worth noting that a clamping sleeve 3 is provided on the other side of the slide rail 4, and the clamping sleeve 3 is fixed to the bottom surface of the mounting seat 2;

[0035] By setting the clamping sleeve 3, during the lifting and lowering movement of the slide rail 4, the clamping sleeve 3 can effectively limit the trajectory of the slide rail 4, thereby ensuring the stability of the lifting and lowering movement of the slide rail 4.

[0036] Further, refer to Figure 1 As shown, it is worth noting that a soft rubber pad is glued on the inner wall of the pipe clamp groove;

[0037] By setting the soft rubber pad, if there is foreign matter between the two groups of clamping blocks 6, when the two groups of clamping blocks 6 are combined to clamp the pipe, the soft rubber pad can appropriately reduce the squeezing force of the upper clamping block 6 on the foreign matter, thereby reducing the squeezing on the operator's fingers.
