Problems solved by technology

[0003] When processing the ribbed tube, the ribbed tube blank is clamped on the fixture of the machine tool, and the slider at the lower part of the fixture is slidingly connected with the slide rail on the machine tool. The rod drives the fixture to slide along the slide rail; when the lead screw stops rotating, the fixture stops at a certain place on the slide rail, and the tool processes the ribbed tube blank. Since the connection and cooperation precision between the lead screw and the fixture is not high, the fixture will be broken during tool processing. Twisting at a small angle or moving in a small range, and the processing accuracy of the rib tube itself is relatively high, which will cause the processed rib tube to fail to meet the requirements

Embodiment 1

[0014] Such as figure 1 As shown, the locking mechanism for processing the external teeth of the rib tube, the locking mechanism for processing the external teeth of the rib tube, includes the boss 4 arranged in the slide rail and the slider 2 arranged at the lower part of the fixture 1 to cooperate with the slide rail track, and It includes a pressure block 3 that can be pressed against the boss 4 under the inner boss 4 of the slide rail, a cylinder 20 arranged on the slider 2, and a spring 5 connecting the pressure block 3 and the slider 2; the cylinder 20 is connected There is a sliding rod 21, and a through hole is provided on the pressing block 3 corresponding to the channel of the sliding block 2, and a connecting rod 31 is arranged in the through hole, one end of the connecting rod 31 is threadedly connected with the sliding rod 21, and the other end of the connecting rod 31 is provided with an anti-off The stopper 32 is convenient to disassemble and install, and the st...

Embodiment 2

[0017] The difference from the first embodiment is that the pressing block and the sliding rod are integrated, the pressing block is provided with a spring seat, one end of the spring is located on the spring seat, and the other end is fixed on the sealing cover.

Embodiment 3

[0019] The difference from Embodiment 1 is: the slider is fixed with a pressure block that can be pressed against the lower part of the boss, the bottom end of the slider is pressed on the boss, the spring is sleeved on the slider, and one end of the spring is against the bottom of the slider. The other end of the spring is against the top surface of the boss.

Abstract

The invention discloses a locking mechanism for machining outer teeth of a rib pipe. The locking mechanism comprises a slide block fitting a slide rail, and further comprises a pressing block fitting and butted against a boss at the upper end of the slide rail and a cylinder barrel arranged on the slide block, wherein a slide rod is connected into the cylinder barrel; and one end of the slide rod extends outside the cylinder barrel, and penetrates through the slide block to be arranged in the pressing block. The mechanism is simple in structure, and is convenient and practical.

Description

technical field [0001] The invention relates to a fixture for processing rib tubes, in particular to a locking mechanism for processing external teeth of rib tubes. Background technique [0002] The finned tube is a tubular heat exchange element with a very good heat exchange effect in electrical equipment, which can achieve the purpose of energy saving and environmental protection. The main structural features of the ribbed tube include the smooth tube, and the outer teeth are plowed on the outer surface of the smooth tube, thereby forming a three-dimensional structure as a whole, which effectively improves the convective heat transfer of the single-phase fluid in the tube and the phase conversion heat in the tube. [0003] When processing the ribbed tube, the ribbed tube blank is clamped on the fixture of the machine tool, and the slider at the lower part of the fixture is slidingly connected with the slide rail on the machine tool. The rod drives the fixture to slide alo...
