Description

Technical Field

[0001] The invention belongs to the technical field of heat treatment equipment, and in particular relates to a supporting and pressing mechanism of an induction quenching machine tool for a straight delivery pipe of a concrete pump truck. Background Art

[0002] The concrete pump truck conveying straight pipe quenching machine mainly drives the inner hole and outer circle sensors to move through the movement of the transformer to scan and heat the supported and compressed pump pipe workpiece. It has strong applicability and can be compatible with the quenching of various types of pump pipe workpieces, but supporting and compressing the workpiece has always been a difficulty.

[0003] In the existing technology, the traditional support is to support the workpiece by forming a V-shape upward with two sets of rollers with a fixed center distance, while the clamping is to prevent the workpiece from jumping around on the circumference by flipping the two sets of rollers with a fixed center distance through a cylinder. The disadvantages are: first, because the center height of the workpiece heated in the pump tube quenching machine is certain, if the workpiece diameter changes, the center distance of the roller group needs to be adjusted, and the rollers need to be repeatedly disassembled and replaced with different roller bases. Second, the outer circle induction heating coil of this structure can only be made into a semicircular structure, resulting in low induction heating efficiency.

[0004] Therefore, it is necessary to invent a new type of support and clamping mechanism to support and clamp different types of pump pipe workpieces, and this mechanism can quickly change and adapt to the entire circle of outer circle sensors to save time and thus improve the workpiece quenching efficiency. Summary of the Invention

[0005] In order to overcome the above shortcomings, the present invention provides an online detection device for a quenching machine tool for pump pipe parts.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A support and clamping mechanism for a straight pipe induction quenching machine tool for a concrete pump truck comprises a base plate, a guide slider, a lead screw, a cylinder mounting plate, a bearing seat, a positioning and centering device, a roller assembly base, a cylinder, a positive and negative thread nut, a dial handwheel, a locking block, a support roller assembly, a clamping roller assembly, two sets of guide rails, and a rolling wheel. The two sets of guide rails are arranged in parallel on the left and right sides of the base plate. The positive and negative thread lead screw nuts are fixed to the end faces of the guide slider on both sides through threads, and are used to adjust the position of the guide slider, thereby controlling the roller assembly base to meet the needs of workpieces with different diameters.

[0008] The locking block is at the front end of the dial handwheel, and a hole for connecting the screw is provided on the locking block. The screw is constrained from rotating by changing the tight fit of the hole to the shaft. The dial handwheel is fixed to the input end of the screw through the hole-shaft matching screw. The positioning and centering device is installed in the middle position of the base plate. The supporting roller group and the clamping roller group are both installed in parallel on the roller group base through threaded connections.

[0009] Further optimization is that the guide rail and the bearing seat are installed on the base plate, and after the rolling wheel is connected to the roller group base, the whole is pushed into the guide rail from the V-shaped parts on both sides of the guide rail end face.

[0010] Further optimization is carried out, in which the cylinder is fixed in the middle position of a set of guide rails by installing a cylinder mounting plate on a guide slider, and the output end of the cylinder is connected to the base of the roller group and then the positive and negative threaded screw nut is installed.

[0011] Further optimization is that the cylinder is threadedly connected and installed on the cylinder mounting plate, the cylinder mounting plate is threadedly connected to the guide slider, both sides of the guide slider are V-shaped structures, and the guide rail is a V-shaped groove corresponding to the guide slider.

[0012] Further optimized, the positioning and centering device can be of any size.

[0013] Further optimization is that a positioning and centering device of different widths is provided between the supporting roller group and the pressing roller group.

[0014] The beneficial effects of the present invention are:

[0015] The present invention changes the number and distance of the support and clamping mechanism distributed in the axial direction of the workpiece according to the workpiece length and workpiece diameter required by the quenching machine to meet the needs of workpieces of different lengths, and at the same time changes the length of the lead screw and the guide rail to meet the needs of workpieces of different diameters. The support and clamping mechanism of the present invention can be modified according to the type of workpiece actually quenched by the machine tool, and has the characteristics of strong adaptability.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings of the present invention.

[0021] A support and clamping mechanism for a straight pipe induction quenching machine tool for a concrete pump truck includes a base plate 1, a guide slider 2, a lead screw 3, a cylinder mounting plate 4, a bearing seat 5, a positioning and centering device 6, a roller assembly base 7, a cylinder 8, a positive and negative thread nut 9, a dial handwheel 10, a locking block 11, a support roller assembly 12, a clamping roller assembly 13, two sets of guide rails 14, and a rolling wheel 15. The guide rails 14 and the bearing seat 5 are mounted on the base plate 1, and the rolling wheel 15 is installed into the guide rails 14 from the end faces of the guide rails 14. The two sets of guide rails 14 are arranged parallel to the left and right sides of the base plate 1. The positive and negative thread lead screw nuts 9 are fixed to the end faces of the guide slider 2 on both sides by threads, and are used to adjust the position of the guide slider 2, thereby controlling the roller assembly base 7 to meet the needs of workpieces with different diameters.

[0022] The locking block 11 is at the front end of the dial handwheel 10. A hole for connecting the screw 3 is set on the locking block 11. The screw 3 is constrained from rotating by changing the tight fit of the hole to the shaft. The dial handwheel 10 is fixed to the input end of the screw 3 through the hole-shaft matching screw. The positioning and centering device 6 is installed in the middle position of the base plate 1. The supporting roller group 12 and the pressing roller group 13 are both installed in parallel on the roller group base 7 through threaded connections.

[0023] The cylinder 8 is fixed to the middle position of the guide rail 14 by installing the cylinder mounting plate 4 on the guide slider 2. The output end of the cylinder is connected to the roller group base 7 and then installed with the positive and negative threaded screw nut 9. The cylinder 8 is threadedly connected and installed on the cylinder mounting plate 4. The cylinder mounting plate 4 is threadedly connected to the guide slider 2. Both sides of the guide slider 2 are V-shaped structures, and the guide rail 14 is a V-shaped groove corresponding to the guide slider 2.

[0024] In the present invention, there is a positioning and centering device 6 of different widths in the middle position of the supporting roller group 12 and the pressing roller group 13 to meet the needs of workpieces with different diameters. The positioning and centering device 6 can be of any size, and the length of the guide rail 14 and the screw 3 is determined according to actual processing needs.

[0025] The present invention realizes support and compression of the workpiece by connecting the cylinder rod of the cylinder 8 to the roller assembly base 7 to move and drive the support roller assembly 12 and the pressure roller assembly 13 to move inward. When the diameter of the workpiece of the quenching machine tool changes, the positioning and centering device 6 is replaced first, and then the torque of the screw 3 is transmitted to the positive and negative thread nut 9 by rotating the dial handwheel 10 to drive the support roller assembly 12 and the pressure roller assembly 13 threaded on the roller assembly base 7 to move, thereby realizing support and compression of the new workpiece. When the outer cylindrical sensor moves axially along the pump pipe and approaches the mechanism, the cylinder rod of the cylinder 8 is connected to the roller assembly base 7 to move and drive the support roller assembly 12 and the pressure roller assembly 13 to move outward to avoid the outer cylindrical sensor. After the outer cylindrical sensor passes through the mechanism, the cylinder rod of the cylinder 8 is connected to the roller assembly base 7 to move and drive the support roller assembly 12 and the pressure roller assembly 13 to move inward to continue to support and compress the workpiece, thereby realizing continuous support and compression of the pump pipe workpiece during quenching.

[0026] The main functions of the present invention's support and clamping mechanism for a concrete pump truck's conveying straight pipe are described above. Furthermore, the number and spacing of these support and clamping mechanisms along the workpiece axis can be adjusted to accommodate workpieces of varying lengths and diameters, depending on the workpiece length and diameter of the quenching machine. Furthermore, the lengths of the lead screw 3 and guide rail 14 can be varied to accommodate workpieces of varying diameters. Therefore, the present invention's support and clamping mechanism can be modified based on the type of workpiece being quenched by the machine, demonstrating its high adaptability.

[0027] The above shows and describes the main features, methods of use, basic principles, and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
