Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of machining, in particular to a fixture for polishing and machining steel pipes. Background Art
[0002] During the machining of steel pipes, burrs and the like on their surfaces need to be polished first. When polishing a steel pipe, it is necessary to clamp and fix the steel pipe to prevent deviation during polishing, which affects the polishing effect. Generally, common fixtures adopt hand-held pliers. This clamping method requires manual clamping and fixing of the steel pipe, and the steel pipe is prone to looseness. Moreover, when a person clamps the steel pipe, only after the steel pipe is polished can another steel pipe be moved in for clamping and polishing. The working efficiency is low, and continuous feeding cannot be achieved, which affects the production efficiency of the enterprise. Summary of the Utility Model
[0003] The purpose of the utility model is to provide a fixture for polishing and machining steel pipes in view of the defects and deficiencies of the prior art.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a fixture for polishing and machining steel pipes, including a base. The innovation lies in that: a storage box with a J-shaped structure is arranged on the base, the top of which is a feeding port and the bottom is a discharging port. A J-shaped accommodating cavity is arranged inside the storage box, and steel pipes are arranged in the accommodating cavity in a row, and the accommodating cavity is in clearance fit with the steel pipes. A supporting plate is arranged at the bottom of the discharging port of the storage box, a baffle is arranged on the side of the supporting plate, and a lifting cylinder is arranged at the bottom of the supporting plate. Slide rails are respectively arranged on the left and right sides outside the discharging port, sliders are arranged inside the slide rails, the sliders are of an L-shaped structure, and a moving slide plate is arranged at the top of the sliders. Clamping cylinders are respectively arranged on the moving slide plates, and an arc-shaped clamping plate is arranged at the end of the piston rod of the clamping cylinder. A rack is arranged along the length direction of the storage box at the turning point of the storage box, and a traveling motor is arranged below the moving slide plate at this position. A gear is arranged on the output shaft of the traveling motor, and the gear is in meshing transmission connection with the rack.
[0005] Further, the supporting plate rises to be flush with the discharging port under the action of the lifting cylinder.
[0006] Further, the clamping plate is made of rubber material, and anti-slip lines are arranged on the inner side.
[0007] Further, a connecting rod is arranged between the moving slide plates for synchronous movement.
[0008] After adopting the above structure, the beneficial effects of the utility model are as follows:
[0009] The utility model can realize automatic material storage and feeding through the setting of a storage bin, achieve continuous blanking, then lift the steel pipe by a supporting plate, clamp the steel pipe by a clamping cylinder and a clamping plate, and then drive the steel pipe to be transported by a traveling motor, so that a polishing machine can polish the steel pipe.

[0015] The following further describes the utility model with reference to the drawings.
[0016] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further details the utility model with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.
[0017] Refer to Figures 1-3A fixture for polishing steel pipes comprises a base 1, a J-shaped material storage box 2 is arranged on the base 1, the top of which is a material feed port and the bottom is a material discharge port, a J-shaped accommodating chamber 3 is arranged inside the material storage box 2, steel pipes are arranged in the accommodating chamber 3, and the accommodating chamber and the steel pipes are matched with each other, a support plate 4 is arranged at the bottom of the material discharge port of the material storage box 2, a baffle 5 is arranged on the side of the support plate 4, a lifting cylinder 6 is arranged at the bottom of the support plate 4, slide rails 7 are arranged on the left and right sides of the outer side of the material discharge port, and sliders 8 are arranged in the slide rails 7, the sliders 8 are L-shaped, and a moving slide plate 9 is arranged on the top of the slide plate 8, a clamping cylinder 10 is arranged on the moving slide plate 9, and an arc-shaped clamping plate 11 is arranged at the end of the piston rod of the clamping cylinder 10, a rack 12 is arranged at the turning point of the material storage box 2 along the length direction of the material storage box, and a travel motor 13 is arranged under the moving slide plate located there, a gear 14 is arranged on the output shaft of the travel motor 13, and the gear 14 is meshed and driven with the rack 12. Specifically, the steel pipes are sequentially placed in the accommodating chamber 3 of the storage box 2, and the steel pipe at the bottom is located at the discharge port. At this time, the lifting cylinder 6 is turned on, and the steel pipe is lifted up by the support plate 4. After it rises to the right position, the clamping cylinder 10 is started at the same time, so that the clamping plate 11 can clamp the steel pipe, and the support plate 4 is lowered and reset. Then the travel motor 13 is turned on to drive the gear 14 to move along the rack 12, that is, the steel pipe is driven to move under the auxiliary action of the slide rail 7 and the slider 8, so that the polishing machine can polish the surface of the steel pipe (see Figure 3 ); The function of the baffle 5 is to block the next steel pipe when the support plate 4 is lifted, so as to prevent the steel pipe from rolling down to the bottom of the support plate during the rising process, thereby affecting the normal unloading.
[0018] In this embodiment, the support plate 4 rises to be flush with the discharge port under the action of the lifting cylinder, that is, the steel pipe is completely lifted to the accommodating cavity 3, which is beneficial to clamping the steel pipe and also beneficial to the movement of the steel pipe.
[0019] In this embodiment, the clamping plate 11 is made of rubber and has anti-slip grooves on the inner side to increase friction and improve the clamping effect.
[0020] In this embodiment, connecting rods 15 are arranged between the moving slides 9 for synchronous movement, so as to ensure that the moving slides 9 on both sides can operate synchronously, thereby facilitating the transportation of the steel pipes.
[0021] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
