Description

Technical Field

[0001] The utility model relates to the technical field of compressor copper tubes, in particular to a stripping mechanism used for expanding the compressor copper tubes. Background Art

[0002] Compressor copper tubes are common components in air conditioning and refrigeration equipment. In order to meet the requirements of installation and air tightness, a structure with a large aperture at one end and a small aperture at another end is usually adopted, and three points are punched on the compressor copper tube as a joint. The original parts are usually straight copper tubes with uniform diameters. The two ends of the cut copper tubes are rough, and they need to be polished at both ends, followed by expansion processing, and then the joint processing. After the expansion of one end of the copper tube is completed by the expansion machine, the expansion head of the expansion machine will bring out the copper tube, and another power needs to be installed to make the copper tube separate from the expansion head, which is costly and requires the cooperation of the two powers.

[0015] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0016] See also Figures 1 to 4The utility model provides a stripping mechanism for expanding the copper tube of a compressor, which is installed on a expanding machine 1. A chuck and a linear rail are respectively arranged on the left and right sides of the upper end of the expanding machine. A slide that moves left and right at the linear rail is equipped with a power-driven slider. The left end of the slider is equipped with an expanding head for expanding the copper tube at the chuck. The chuck includes a slide rail 2 that is horizontally arranged on the upper end of the slider of the expanding machine 1. The slide rail 2 is equipped with a slide 3 that is elastically connected to the expanding machine 1 and moves left and right. The slide 3 is concave. The slide 3 is a type of expansion machine, and a T-shaped slide groove that is slidably matched to the slide rail 2 is arranged in the middle of the lower end of the slide 3. The slide can adapt to the expansion machine. The front and rear sides of the left end of the slide 3 are horizontally and symmetrically provided with connecting rods. The left ends of the two connecting rods are longitudinally provided with mounting plates 5. The middle of the mounting plate 5 is provided with a stopper sleeve 6 that is sleeved on the expansion head of the expansion machine 1. The front and rear sides of the upper end of the linear rail of the expansion machine 1 are symmetrically provided with limit blocks 7 that limit the slide 3. The right end of the slide rail 2 is provided with a push block 8 for pushing the slide 3. The slider drives the expansion head to move left, and the push block on the slider pushes the slider to move left together. The slider moves left with the stopper sleeve through the connecting rod and the mounting plate. After the expansion is completed, the slider drives the expansion head with the copper tube to move right and reset. The slide and the stopper sleeve move right with the push block under the action of elasticity. The slide and the stopper sleeve are blocked by the limit block in the middle, so that the expansion head moves right relative to the stopper sleeve, and the copper tube on the expansion head is blocked by the stopper sleeve and detached.

[0017] Stabilizing plates 9 are symmetrically arranged on the front and rear sides of the right end of the linear rail of the expanding machine 1, and an elastic member is connected between the slide 3 and the stabilizing plate 9. Under the action of the elastic member, the slide and the stopper move with the push block and are stopped by the stopper and then abut against the stopper, so that the expanding head moves rightward relative to the stopper, and the copper tube on the expanding head is stopped by the stopper and detached.

[0018] The connecting rod is a screw rod 4, and the mounting plate 5 is passed through the screw rod 4 and locked by a nut. The screw rod is simple and convenient to obtain, and the mounting plate can be adjusted to the left and right position by the nut, thereby adjusting the left and right position of the stopper, so as to adapt to copper pipes of different lengths.

[0019] See also Figure 1 , Figure 4 The mounting plate 5 is composed of a middle square plate connected to long plates at both sides, and the retaining sleeve 6 is locked to the square plate by a locking bolt. The above arrangement can reduce the weight of the mounting plate, thereby stabilizing the structure and reducing the burden.

[0020] The bottom of the square plate extends obliquely from the upper right to the lower left to form a guide plate. The copper pipes that fall off can be guided to other places for collection through the guide plate.

[0021] The utility model discloses a material stripping mechanism for expanding a copper tube of a compressor: the copper tube can be automatically separated from the expanding head by the power of an expanding machine, and the utility model has the advantages of low cost, simplicity and effectiveness.

[0022] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
