[0020] First embodiment

[0021] See also Figure 1-2 , Figure 1 It is a schematic diagram of the overall structure of the rectangular tube fixing and clamping device of the first embodiment of the utility model. Figure 2 It is a cross-sectional schematic diagram along the latch pin 103 of the rectangular tube fixing and clamping device of the first embodiment of the utility model.

[0022] The utility model provides a rectangular tube fixing and clamping device: comprising a bracket 101 and an adjustment component, the adjustment component comprising a clamp 102, a latch 103, a tension spring 104, a drive block, a clamp plate 105, a moving block and a clamp block 106, the drive block comprising a hydraulic cylinder 107 and a first telescopic rod 108, the moving block comprising an electric cylinder 109 and a second telescopic rod 110, and the bracket 101 having four clamping slots 111. The above-mentioned scheme solves the problem that the depth of the clamp 102 inserted into the clamping slot 111 is fixed, resulting in the clamp 102 being able to limit and fix rectangular tubes of a single size, and being unable to limit and fix rectangular tubes of different sizes. It can be understood that the above-mentioned scheme can be used in the scenario where the depth of the clamp 102 inserted into the clamping slot 111 needs to be adjusted when limiting and fixing rectangular tubes of different sizes, and can also be used to solve the problem that the existing fixing and clamping device cannot rotate the rectangular tube, thereby being unable to realize the bending resistance detection of different ends of the rectangular tube.

[0023] In this embodiment, the adjustment component is located above the bracket 101, and is used to adjust the width and height dimensions inside the clamp 102, so that the clamp 102 can limit and fix rectangular tubes of different sizes, thereby eliminating the need to replace the clamp 102, thereby reducing the use cost of the clamp 102.

[0024] The slots 111 are respectively located at the four corners of the top of the bracket 101, the clamp 102 is arranged on the bracket 101, and the bottom end of the clamp 102 is inserted into the slot 111, the latch 103 is slidably connected with the clamp 102 and the bracket 101 respectively, the latch 103 passes through the clamp 102 and the bracket 101, the tension spring 104 is fixed between the latch 103 and the bracket 101, and the driving block is used to drive the clamp 105 to move. The clamping plate 105 is located on the side of the driving block away from the clamp 102, the moving block is used to move the clamping block 106, the clamping block 106 is located on the side of the moving block away from the clamp 102, the clamp 102 is in a U-shape, the bottom end of the clamp 102 cooperates with the clamping groove 111, so that the bottom end of the clamp 102 can be inserted into the clamping groove 111, the bottom end of the clamp 102 and the bracket 101 both have through holes, and the through holes of the bracket 101 are connected to the clamping groove 111. The latch 103 can be inserted into the through holes of the clamp 102 and the bracket 101, so that the latch 103 can lock the clamp 102 in the through hole of the bracket 101, thereby limiting and fixing the clamp 102 in the bracket 101. The tension spring 104 has a damper. When the tension spring 104 generates telescopic shaking, the damper of the tension spring 104 generates a damping force to prevent the tension spring 104 from telescopic shaking, thereby making the tension spring The expansion and contraction shaking of the spring 104 will eventually stop and will not keep shaking. A clamp 105 is provided in each of the clamps 102, and the clamp 105 can move up and down in the clamp 102, so that the clamp 105 can clamp and fix the height dimension of the rectangular tube. Two clamp blocks 106 are provided in each of the clamps 102, and the two clamp blocks 106 can move relative to or away from each other in the clamp 102, so that the clamp blocks 106 can clamp and fix the width dimension of the rectangular tube.

[0025] Secondly, the hydraulic cylinder 107 is fixed on the inner side of the clamp 102; the two ends of the first telescopic rod 108 are respectively connected to the output end of the hydraulic cylinder 107 and the clamp 105, the first telescopic rod 108 is located between the hydraulic cylinder 107 and the clamp 105, the output end of the hydraulic cylinder 107 is connected to the first telescopic rod 108, and drives the first telescopic rod 108 to extend and retract, thereby driving the clamp 105 to move up and down in the clamp 102, so that the clamp 105 can clamp and fix the height size of the rectangular tube.

[0026] Finally, the electric cylinder 109 is fixed on the inner side of the clamp 102; the two ends of the second telescopic rod 110 are respectively connected to the output end of the electric cylinder 109 and the clamp block 106, the second telescopic rod 110 is located between the electric cylinder 109 and the clamp block 106, the output end of the electric cylinder 109 is connected to the second telescopic rod 110, and drives the second telescopic rod 110 to extend and retract, thereby driving the two clamp blocks 106 to move relative to or away from each other in the clamp 102, so that the clamp block 106 can clamp and fix the width size of the rectangular tube.

[0027] When using the utility model, when it is necessary to test the bending resistance of the rectangular tube, the rectangular tube is placed on the bracket 101, and then the latch 103 is pulled outward to allow the latch 103 to move out of the slot 111, so that the tension spring 104 is stretched. When the latch 103 is completely moved out of the slot 111 into the through hole of the bracket 101, the latch 103 will not hinder the insertion of the clamp 102 into the slot 111. At this time, the bottom end of the clamp 102 is aligned with the slot 111 and the clamp is inserted into the slot 111. The hoop 102 is inserted into the slot 111. When the bottom end of the hoop 102 is fully inserted into the slot 111, the through hole of the hoop 102 is fully aligned with the through hole of the bracket 101.

Since the tension spring 104 has a self-restoring effect, the tension spring 104 drives the latch 103 to move in the direction of restoring to the original position, so that the latch 103 is gradually inserted into the through hole of the hoop 102. When the latch 103 is fully inserted into the through hole of the clamp 102, the clamp 102 is limited and fixed in the bracket 101, so that the clamp 102 is installed and fixed, and then the hydraulic cylinder 107 is started, so that the power output from the output end of the hydraulic cylinder 107 drives the first telescopic rod 108 to extend and retract, thereby driving the clamp 105 to move up and down in the clamp 102, so that the clamp 105 can clamp and fix the height size of the rectangular tube, and the electric cylinder 109 is started, so that the electric cylinder The power output from the output end of 109 drives the second telescopic rod 110 to extend and retract, thereby driving the two clamping blocks 106 to move relative to or away from each other in the clamp 102, so that the clamping blocks 106 can clamp and fix the width dimension of the rectangular tube, and the height dimension and width dimension of the rectangular tube are clamped and fixed by the clamp plate 105 and the clamping blocks 106 respectively, so that the clamp 102 can limit and fix rectangular tubes of different sizes, thereby eliminating the need to replace the clamp 102, thereby reducing the use cost of the clamp 102.

[0028] Second embodiment

[0029] See also Figure 3-4 , Figure 3 This is a schematic structural diagram of a rotating assembly of a rectangular tube fixing and clamping device according to a second embodiment of the utility model. Figure 4 FIG. 2 is a cross-sectional schematic diagram of a rectangular tube fixing and clamping device of the second embodiment of the utility model along the rotating shaft 204. Based on the first embodiment, a rectangular tube fixing and clamping device of the utility model further includes a rotating assembly, and the rotating assembly includes a rotating plate 201, a base 202, a control motor 203 and a rotating shaft 204.

[0030] The rotating assembly is arranged below the bracket 101. By arranging the rotating assembly, the rotating assembly can drive the bracket 101 to rotate, so that the bending resistance of the two end faces of the rectangular tube can be tested without disassembling the rectangular tube, thereby improving the testing efficiency of the rectangular tube.

[0031] The rotating plate 201 is fixed on the lower surface of the bracket 101; the base 202 is rotatably connected to the rotating plate 201 and is located on the outside of the rotating plate 201 and below the bracket 101. The base 202 has a rotating groove, and the rotating plate 201 cooperates with the rotating groove of the base 202 and can rotate along its own axis in the rotating groove of the base 202.

[0032] The control motor 203 is fixed on the inner side of the base 202; the two sides of the rotating shaft 204 are respectively connected to the output end of the control motor 203 and the rotating plate 201, and the rotating shaft 204 is located between the control motor 203 and the rotating plate 201. The output end of the control motor 203 is connected to the rotating shaft 204 and drives the rotating shaft 204 to rotate along its own axis, thereby driving the rotating plate 201 to rotate along its own axis in the rotating groove of the base 202.

[0033] After the bending resistance performance test is performed on one end face of the rectangular tube, the control motor 203 is started, so that the power output from the output end of the control motor 203 drives the rotating shaft 204 to rotate along its own axis, thereby driving the rotating plate 201 to rotate along its own axis in the rotating groove of the base 202, and then driving the bracket 101 to rotate along the axis of the rotating plate 201 above the base 202. Through the rotation of the bracket 101 above the base 202 along the axis of the rotating plate 201, the rectangular tube clamped and fixed above the bracket 101 can be driven to rotate above the base 202 along the axis of the rotating plate 201, and then the other end face of the rectangular tube can be moved to the detection device for detection. By rotating the rectangular tube after the bending resistance performance test is performed on one end face of the rectangular tube, so as to facilitate moving the other end face of the rectangular tube to the detection device for detection, the bending resistance performance test can be performed on the two end faces of the rectangular tube without disassembling the rectangular tube, thereby improving the detection efficiency of the rectangular tube.

Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope covered by the utility model.
