Description

Technical Field

[0001] The utility model relates to the technical field of numerical control sawing machines, in particular to a gantry type numerical control sawing machine servo mechanism. Background Art

[0002] The fully automatic gantry CNC sawing machine is generally divided into a cutting mechanism and an automatic feeding mechanism. In the prior art, the servo feeding structure of the sawing machine usually adopts two sets of clamps. One set of clamps plays a positioning role when the cutting mechanism is cutting, and the other set of clamps plays a role of clamping the pipe and pushing it forward, thereby realizing automatic feeding and cutting of the pipe.

[0003] Chinese patent CN203437987U discloses a servo screw automatic feeding mechanism for a fully automatic horizontal band saw, including a guide rail seat, a planetary reducer mounted on the screw mounting seat, and a servo motor equipped with a pulse signal sending device and an encoder feedback signal device. The utility model is easy to use, has accurate feeding length and precision, high feeding efficiency, good feeding effect, and is conducive to promotion.

[0004] The device can improve the accuracy of feeding length by adopting a screw rod and a servo motor to drive the feeding mechanism, but the device still needs two sets of clamps to feed the pipe. When the clamps in the rear group are displaced in the left and right directions during use, the distance between the two clamps in the rear group will be greater than the distance between the two clamps in the front group. At this time, if the clamps in the rear group clamp the pipe forward, one end of the pipe will rub against one side of the clamps in the front group. The friction force causes the feeding length of the pipe to be different each time, thereby affecting the cutting accuracy of the pipe length. Utility Model Content

[0005] The utility model aims to provide a gantry type numerical control sawing machine servo mechanism to solve the problem that when two sets of clamps have different widths, the pipe length error is large and the length does not meet the standard because it cannot be discovered in time.

[0007] The feeding mechanism comprises a front clamp and a feeding clamp, two of each of the front clamp and the feeding clamp are provided, a horizontal driving mechanism of the front clamp is provided in the frame, and an alignment detection component is provided between the front clamp and the feeding clamp;

[0008] The alignment detection component includes an active infrared transmitter and a passive infrared receiver, and one side of the front clamp and the feeding clamp is respectively provided with a mounting structure for installing the active infrared transmitter and the passive infrared receiver;

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a gantry type CNC sawing machine servo mechanism, comprising a frame 1, a gantry frame 2 is installed at one end of the frame 1, a saw blade 3 and a cutting drive 4 of the saw blade 3 are arranged on one side of the gantry frame 2, a discharge port 5 is arranged below the saw blade 3, a feeding trough 6 is arranged on the upper surface of the frame 1, a feeding mechanism 7 and a feeding drive 8 of the feeding mechanism 7 are arranged in the feeding trough 6;

[0023] The feeding mechanism 7 feeds the pipe to the feeding trough 6, and the saw blade 3 and the saw blade 3 cutting drive 4 are arranged to drive the saw blade 3 to move, thereby cutting the pipe.

[0024] The feeding mechanism 7 includes a front clamp 701 and a feeding clamp 702, two of which are provided, a horizontal driving mechanism of the front clamp 701 is provided in the frame 1, and an alignment detection component 9 is provided between the front clamp 701 and the feeding clamp 702. By providing the front clamp 701, when the saw blade 3 is cutting, the front clamp 701 clamps both sides of the pipe, and the two front clamps are driven to approach each other by providing the horizontal driving mechanism.

[0025] The alignment detection component 9 includes an active infrared transmitter 901 and a passive infrared receiver 902 . One side of the front clamp 701 and the feeding clamp 702 is respectively provided with a mounting structure for installing the active infrared transmitter 901 and the passive infrared receiver 902 .

[0026] By setting the detection component, the active infrared transmitter 901 and the passive infrared receiver 902 are operated. When the front clamp 701 and the feeding clamp 702 are misaligned, it can be displayed on the control panel terminal of the CNC sawing machine so that the operator can find it in time.

[0027] The alignment detection assembly 9 also includes a pressure sensor 903 . A limit plate 10 is fixed in the feeding trough 6 . The pressure sensor 903 is installed on one side of the limit plate 10 close to the feeding clamp 702 .

[0028] The mounting structure includes a fixing seat 904, a groove 905 is formed on one side of the fixing seat 904, a first magnetic sheet 906 is fixed in the groove 905, a second magnetic sheet 907 is fixed on one side of the active infrared transmitter 901 and the passive infrared receiver 902, and the first magnetic sheet 906 and the second magnetic sheet 907 are attracted to each other.

[0029] By providing the installation structure, the active infrared transmitter 901 and the passive infrared receiver 902 can be quickly installed, and can be easily disassembled, replaced, and maintained.

[0030] The feeding drive 8 includes a longitudinal electric slide 801, which is installed on both sides of the frame 1. A guide frame 802 is installed on the movable platform of the longitudinal electric slide 801, a horizontal electric slide 803 is installed above the guide frame 802, and the feeding clamp 702 is installed on the movable platform of the horizontal electric slide 803.

[0031] Start the horizontal electric slide 803 to make the feeding clamps 702 on both sides move closer to each other and clamp the pipe. When the longitudinal electric slide 801 is started again, the guide frame 802 moves towards or away from the front clamp 701, and the pipe is transported forward by clamping the feeding clamp 702.

[0032] A fixing frame 12 is fixed in the feeding trough 6 . Two fixing frames 12 are provided. A rolling roller 11 is rotatably connected between the two fixing frames 12 . A sprocket 13 is fixed to one end of the rolling roller 11 . A transmission chain 14 of the sprocket 13 is provided between adjacent sprockets 13 .

[0033] By setting the rolling roller 11, the friction of the pipe on the machine tool is reduced. A driving motor for driving one of the sprockets 13 to rotate is set on one side of the fixed frame 12. After the driving motor is started, the sprocket 13 drives the multiple rolling rollers 11 to rotate synchronously through the transmission chain 14.

[0034] The horizontal driving mechanism includes a screw rod 703, which is rotatably connected in the frame 1, and a front clamp 701 is threadedly connected to the outer wall of the screw rod 703. The front clamp 701 is slidably connected to one side of the limit plate 10, and a servo motor 704 for driving the screw rod 703 to rotate is installed on one side of the frame 1; after starting the servo motor 704, the screw rod 703 rotates, and when the limit plate 10 limits the front clamp 701, the front clamp 701 moves to clamp the pipe.

[0035] When in use, the horizontal electric slide 803 is started to make the feeding clamps 702 on both sides approach each other to clamp the pipe, and then the longitudinal electric slide 801 is started to make the guide frame 802 move in the direction close to the front clamp 701 to transport the pipe forward. When the longitudinal electric slide 801 reaches the preset stroke, one side of the feeding clamp 702 presses the pressure sensor 903, and the pipe is transported to the feeding trough 6. The saw blade 3 and the saw blade 3 cutting drive 4 are set to drive the saw blade 3 to move and cut the pipe, wherein the cutting drive 4 is the same as the prior art;

[0036] When the front clamp 701 and the feeding clamp 702 are misaligned, the active infrared transmitter 901 and the passive infrared receiver 902 cannot be aligned while the pressure sensor 903 is squeezed. At this time, the control panel terminal of the CNC sawing machine displays the misalignment, so that the operator can find out in time and correct the position of the feeding clamp 702.

[0037] This method can prevent the misalignment of the front and rear sets of clamps during pipe feeding, which would increase the friction between one end of the pipe and one side of the front clamp 701, leading to problems such as misfeeding and inaccurate cutting length.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
