[0001] The utility model relates to the technical field of clamping tooling for processing flange covers, in particular to a matching clamping tooling for processing flange covers. Background Art

[0002] Flange cover refers to a connecting component that connects pipes, valves and equipment. The installation and disassembly of flange cover are relatively convenient and it is widely used in the oil, natural gas, chemical, pharmaceutical and other industries. Flange cover is mostly made of metal. In order to improve the aesthetics and corrosion resistance of the product, the surface of the flange cover will be polished. At this time, a matching clamping tooling is needed for flange cover processing.

This process is time-consuming and the flexibility of the clamping tooling is poor, which affects the progress and efficiency of the polishing process. Therefore, a matching clamping tooling for flange cover processing is proposed to solve the above-mentioned problems. Utility Model Content

[0008] The beneficial effects of the present invention are as follows: through the cooperation between the first bidirectional threaded connecting rod, the transverse wall, the rotating rod and the clamping arm, the flange cover can be clamped under the drive of the driving mechanism, and the positioning of the rotating rod by the positioning component is released, and the clamped flange cover is rotated under the action of force. When it is rotated to a suitable polishing processing position, the rotating rod is positioned by the positioning component again, so that when the flange cover is clamped at different angles for polishing operations, there is no need to repeatedly disassemble and assemble the flange cover, making the clamping tooling more convenient and flexible, thereby improving the progress and efficiency of the polishing process.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0031] The driving mechanism 3 is composed of a stepping motor 31 and a worm gear reducer 32. The right side of the carrying seat 1 is fixedly provided with a worm gear reducer 32 whose output end is transmission-connected to the end of the first bidirectional threaded connecting rod 2. The top of the worm gear reducer 32 is fixedly provided with a stepping motor 31 whose output end is transmission-connected to the input end of the worm gear reducer 32.

[0032] Wherein: a limiting groove 101 is provided on the surface of the supporting seat 1, and the two transverse walls 4 pass through the limiting groove 101;

[0033] After the stepper motor 31 is powered on and started, the kinetic energy is transmitted to the worm gear reducer 32 through its output end, and the output end of the worm gear reducer 32 drives the first bidirectional threaded connecting rod 2 to rotate. At the same time, after the worm gear reducer 32 stops working, it can realize a self-locking function. Under the push of the threads and the limit of the limit groove 101, the two transverse walls 4, which are threadedly connected to the first bidirectional threaded connecting rod 2, indirectly drive the two clamping arms 6 to move to opposite sides, thereby achieving the support of the flange cover;

[0034] Among them, one of the rotating rods 5 has an outer surface with annular positioning grooves 51 distributed at equal distances;

After the stepping motor 31 is powered on and started, its output end transmits kinetic energy to the worm gear reducer 32. The output end of the worm gear reducer 32 drives the first bidirectional threaded connecting rod 2 to rotate. Driven by the threads and limited by the limiting grooves 101, the two transverse walls 4 move toward opposite sides, thereby driving the two clamping arms 6 to clamp and fix the flange cover, and the upper surface of the flange cover can be polished.

[0041] When the locking cam 73 is in the unlocked position, the locking cam 72 is released, and the locking cam 73 is in the unlocked position ...

[0042] Example 2, by Figure 1 Provided is a cooperating clamping tool for flange cover processing. The utility model includes a load-bearing seat 1, a first bidirectional threaded connecting rod 2, a driving mechanism 3, two transverse walls 4 and two clamping arms 6. The first bidirectional threaded connecting rod 2 is rotatably arranged inside the load-bearing seat 1 through a bearing.

The two rotating rods 5 are both fixedly provided with a clamping arm 6 on one side, and a positioning component 7 for limiting one of the rotating rods 5 is provided on one of the transverse walls 4.

[0043] The support frame includes a base 9, a second bidirectional threaded screw 10, two threaded rings 11, and two hinge assemblies 12. The second bidirectional threaded screw 10 is rotatably arranged inside the base 9 through a bearing. The outer surface of the second bidirectional threaded screw 10 is threadedly connected with the threaded rings 11 that are symmetrically distributed. The outer surface of the threaded ring 11 is hinged to the support seat 1 through the hinge assembly 12.

[0044] The hinge assembly 12 is composed of two hinged seats 121 and a connecting rod 122. The two hinged seats 121 are respectively fixed to the bottom end of the supporting seat 1 and the outer surface of the threaded ring 11. The two hinged seats 121 on the same side are hingedly connected by the connecting rod 122.

[0045] During the rotation of the second bidirectional threaded screw 10, the two threaded rings 11 threadedly connected thereto will move to the opposite side. With the cooperation of the hinge assembly 12, the distance between the load-bearing seat 1 and the base 9 can be indirectly changed, so that the clamping tool can be adapted to people of different heights during use, thereby improving its applicability.

[0048] Working principle:

[0049] First: by turning the handle, the second bidirectional threaded screw 10 is rotated with the help of the bearing. At this time, the two threaded rings 11 threadedly connected to the second bidirectional threaded screw 10 cooperate with the anti-drift groove 91 and the anti-drift wheel 111. The threaded ring 11 moves laterally to the opposite side stably, and the articulated seat 121 connected to the two threaded rings 11 drives the connecting rod 122 to move, which can change the distance between the load-bearing seat 1 and the base 9, so that the clamping tooling can be adapted to people of different heights during use, thereby improving its applicability.
